2. Background Art Generally, currently available ozone generators can be classified into three types, i. e. a gaseous discharge type, an ultraviolet-ray type and an electrolysis type. These types of ozone generators have problems and restrictions, such as large volume, heavy weight, high power consumption, low efficiency and the like.

Particularly, in case of the gaseous discharge type ozone generator, when ozone produced in a gaseous state is injected into water (H2O), it is extremely difficult for ozone not only to be dissolved in the water, but also to be uniformly dissolved in the water. Additionally, when ozone is injected into the water, a high percentage of the ozone, about 50 %, is released back from the water and dispersed into atmosphere. Since high concentrations of ozone are dangerous to the human body and the environment, it is necessary to provide a technology for disposing of the high concentration ozone exhausted to the atmosphere, causing restrictions in widespread use of the gaseous discharge type ozone generator.

Thus, as a more effective method for safely generating ozone, it may be suggested to provide a method for generating anions in

water. This technology can solve the problems of the troublesome and complicated process of generating ozone outside of the water and then injecting it into the water, non-uniform distribution of ozone in a container, danger caused by out-flow of ozone and the like.

5. Modes for Carrying out the Invention Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily understand and repeat the present invention.

An in-water discharging core according to the present invention must be designed such that even if an extremely low voltage is applied thereto, the in-water discharging core can induce in-water discharge and generate a large quantity of anions.

In order to generate the anions with the low voltage, a water

breakdown mechanism (which is also referred to as in-water discharging) must be employed. The in-water discharging is carried out by a bubble mechanism, based on the principle that when a voltage is applied to a cathode, impurities ionized in the water, OH-ions ionized by electrolysis of the water and the like form nucleation sites at sharp protrusions of the cathode, so that an extremely high localized electric field region is formed at the site and induces local heating, causing evaporation of water molecules (H2O) to generate the bubbles. Thus, when the bubbles are generated, the bubbles are expanded at a high speed in the direction from the cathode to an anode, forming a conduction channel between two electrodes. This is the in-water discharging based on the bubble mechanism. In this mechanism, as tips of the cathode and anode are made sharper, the discharging occurs with a lower voltage. Further, a quantity of active oxygen generated by the in-water discharging is proportional to the number of point electrodes (which is also referred to as in-water discharging cells), which enables the in-water discharging.

The inventors have paid attention to the fact that the in-water discharging core can be operated in the dielectrics provided in the form of water, and developed a completely new idea departing from the electrode structures having an etched-type platinum plate generally used in the prior art.

That is, as shown in Fig. 14, provided that switches SW powered by a power supply 40 are immersed in water contained in a container 30, the water itself acts as a switching medium for the switches and platinum wires 20 and 22 act as cathodes and anodes, respectively. If a voltage above a predetermined limit is applied to the switches, the switches, that is, the in-water discharging cells conduct a self-switching operation and are broken down due to the breakdown mechanism of water. The self switching-operation of the in-water discharging cells causes a conduction channel to be formed between the cathodes and the

anodes. When the voltage between the cathodes and the anodes of the in-water discharging cells is 0 V, the water in the barrel fills paths between the cathodes and the anodes, so that a voltage distribution is again generated between the anodes and the cathodes (what is referred to as self-recovery process of the water). That is, while the self-switching operation and the self-recovery process of the water are repeated, the in-water discharging occurs continuously, so that the anions are effectively generated.

An in-water discharging core 100 according to an embodiment of the invention employing the in-water discharging system described above is shown in Fig. 1. Constitution and an assembling method of the in-water discharging core 100 according to the embodiment of the invention will now be described in detail with reference to Figs. 2 to 11.

Figs. 2 and 3 are perspective views illustrating an example of a frame, which may be employed in the in-water discharging core of the present invention.

As shown in Figs. 2 and 3, a frame 10 comprises a square-shaped frame body defining a plurality of square shaped openings 16 at the center of the body, and legs 11A and 11B at opposite sides of the frame body. The frame 10 is made of an insulating material, such as polycarbonate.

Specifically, the frame 10 comprises a first side 12 to which the legs 11A and 11B are attached at opposite side of the first side. The first side 12 has extensions respectively extending in opposite directions from the frame body. The extensions are respectively formed with relatively large apertures 12D and 12E at outer portions thereof in the direction parallel to the frame body, and with relatively small apertures 12G and 12F in the direction parallel to the frame body at inner portions of the extensions where the relatively small apertures are matched to the frame body. The first side 12 is formed with ridges 12A and

12I on upper and lower surfaces thereof, respectively, such that the ridges are protruded from positions where the upper and lower surfaces of the first side 12 are roughly flush with upper and lower surfaces the frame body, respectively. The first side 12 of the frame 10 is formed with an elongated groove 12H between the apertures 12G and 12F. The elongated groove 12H is connected to the aperture 12G at one end of the groove, and at other end of the groove, the elongated groove 12H extends to a position slightly spaced from the aperture 12G and corresponding to the end of the ridges 12A and 121. At the other end of the elongated groove 12H, the first side 12 is provided with a protrusion 12J such that the protrusion is protruded through the groove in the direction perpendicular to the ridges 12A and 12I. The first side 12 of the frame 10 is formed with a mushroom-shaped protrusion 12B on the upper surface of the first side in the direction of the ridge 12A at a position corresponding to the leg 11A, and with another mushroom-shaped protrusion 12C on a surface opposite to the protruded direction of the leg 11B at a position corresponding to the leg 11B between the apertures 12E and 12F in the direction perpendicular to the ridges 12A and 121. Valleys between the ridges 12A and 12A ; 12I and 12I are preferably formed with a pitch of about 0. 5-1. 5 mm, respectively, and the pitch of the valleys must be determined in consideration of the heat expansion coefficient of the platinum wire to be wound around the valleys of the ridges. The pitch of the valleys can also be varied depending on the number of the openings 16 formed in the frame 10. As the number of the openings 16 is increased, the pitch of the valleys may be reduced.

The frame 10 further comprises a second side 13 contacting the first side 12 at the position corresponding to the leg 11A.

The second side 13 of the frame 10 is formed with ridges 13A and 13D on upper and lower surfaces of the second side 13, and with an elongated groove 13D on the outer surface thereof in the

lengthwise direction. The elongated groove 13C is connected to the aperture 12F at one end of the elongated groove 13C, and at other end of the elongated groove 13C, the elongated groove 13C extends to a position corresponding to the end of the ridges 13A and 13D. Further, at the other end of the elongated groove 13C, the second side 13 is provided with a protrusion 13B, such that the protrusion is protruded through the groove in the direction perpendicular to the ridges 13A and 13D. Meanwhile, a plane constituted by valleys formed between the ridges 13A and 13A; 13D and 13D of the second side 13 of the frame 10 is different from a plane constituted by the valleys formed between the ridges 12A and 12A; 12I and 121 of the first side 12. That is, the plane constituted by the valleys formed between the ridges 13A and 13A; 13D and 13D of the second side 13 is preferably about 0. 5-1. 5 mm higher than the plane constituted by the valleys formed between the ridges 12A and 12A; 12I and 12I of the first side 12. The height difference must be determined under consideration of the heat expansion coefficient of the platinum wire to be wound along the valleys of the ridges. Additionally, the height difference can also be varied depending on the number of the openings 16 formed in the frame 10. As the number of the openings 16 is increased, the height difference may be reduced. The valleys between the ridges 13A and 13A; 13D and 13D are preferably formed with a pitch of about 0. 5-1. 5 mm, respectively, and the pitch of the valleys must be determined under consideration of the heat expansion coefficient of the platinum wire to be wound around the valleys of the ridges. The pitch of the valleys can also be varied depending on the number of the openings 16 formed in the frame 10. As the number of the openings 16 is increased, the pitch of the valleys may be reduced.

The frame 10 further comprises a third side 14 contacting the second side 13 and parallel to the first side 12. The third side 14 of the frame 10 is formed with ridges 14A and 14B on upper

and lower surfaces of the third side 14. A plane constituted by valleys formed between the ridges 14A and 14A; 14B and 14B of the third side 14 of the frame 10 is the same as the plane constituted by the valleys formed between the ridges 12A and 12A; 12I and 12I of the first side 12. That is, the plane constituted by valleys formed between the ridges 14A and 14A; 14B and 14B of the third side 14 is also preferably about 0. 5-1. 5 mm higher than the plane constituted by the valleys formed between the ridges 13A and 13A; 13D and 13D of the second side 13. Further, the valleys between the ridges 14A and 14A; 14B and 14B are preferably formed with a pitch of about 0. 5-1. 5 mm, respectively, and the pitch of the valleys must be determined under consideration of the heat expansion coefficient of the platinum wire to be wound around the valleys of the ridges. The pitch of the valleys can also be varied depending on the number of the openings 16 formed in the frame 10. As the number of the openings 16 is increased, the pitch of the valleys may be reduced.

The frame 10 further comprises a fourth side 15 contacting both the third side 13 and the first side 12, while being parallel to the second side 13. The fourth side 15 of the frame 10 is formed with ridges 15A and 15B on upper and lower surfaces of the third side 15 (see Fig. 7). A plane constituted by valleys formed between the ridges 15A and 15A; 15B and 15B of the fourth side 15 of the frame 10 is the same as the plane constituted by the valleys formed between the ridges 13A and 13A; 13D and 13D of the second side 13. That is, the plane constituted by valleys formed between the ridges 15A and 15A; 15B and 15B of the fourth side 15 is also preferably about 0. 5-1. 5 mm higher than the plane constituted by the valleys formed between the ridges 12A and 12A; 121 and 121 of the first side 12. Further, the valleys formed between the ridges 15A and 15A; 15B and 15B are preferably formed with a pitch of about 0. 5 ~ 1. 5 mm, respectively, and the pitch of the valleys must be determined under consideration of the heat

expansion coefficient of the platinum wire to be wound around the valleys of the ridges. The pitch of the valleys can also be varied depending on the number of the openings 16 formed in the frame 10. As the number of the openings 16 is increased, the pitch of the valleys may be reduced.

The frame 10 further comprises a plurality of first compartments 17 and 17 formed between the first side 12 and the third side 14 in the direction parallel to the second and fourth sides 13 and 15 for separating the openings 16. The first compartments 17 are also formed with ridges 17A and 17B on their upper and lower surfaces. A plane constituted by valleys formed between the ridges 17A and 17A; 17B and 17B of each of the first compartments 17 is different from the plane constituted by the valleys formed between the ridges 13A and 13A ; 13D and 13D of the second side 13 or by the valleys formed between the ridges 15A and 15A; 15B and 15B of the fourth side 15. Thus, the valleys formed between the ridges 17A and 17A; 17B and 17B of each of the first compartments 17 are also preferably about 0. 5 ~ 1. 5 mm higher than the valleys formed between the ridges 12A and 12A ; 12I and 12I of the first side 12 and the valleys formed between the ridges 14A and 14A; 14B and 14B of the third side 14. Further, the valleys formed between the ridges 17A and 17A; 17B and 17B are preferably formed with a pitch of about 0. 5-1. 5 mm, respectively, and the pitch of the valleys must be determined under consideration of the heat expansion coefficient of the platinum wire to be wound around the valleys of the ridges. The pitch of the valleys can also be varied depending on the number of the openings 16 formed in the frame 10. As the number of the openings 16 is increased, the pitch of the valleys may be reduced.

The frame 10 further comprises a plurality of second compartments 18 and 18 formed between the second side 13 and the fourth side 15 in the direction parallel to the first and third sides 12 and 14 for separating the openings 16. The second

compartments 18 are also formed with ridges 18A on their upper and lower surfaces (not shown, however, the ridges on the lower surface are depicted by reference numeral 18B for convenience of the explanation). A plane constituted by valleys formed between the ridges 18A and 18A; 18B and 18B of each of the second compartments 18 is the same as the plane constituted by the valleys formed between the ridges 12A and 12A; 12I and 12I of the first side 12 or by the valleys formed between the ridges 14A and 14A; 14B and 14B of the third side 14. Thus, the valleys formed between the ridges 18A and 18A; 18B and 18B of each of the second compartments 18 are also preferably about 0. 5-1. 5 mm higher than the valleys formed between the ridges 13A and 13A; 13D and 13D of the second side 13 or the valleys formed between the ridges 15A and 15A ; 15B and 15B of the fourth side 15. Further, the valleys formed between the ridges 18A and 18A ; 18B and 18B are preferably formed with a pitch of about 0. 5-1. 5 mm, respectively, and the pitch of the valleys must be determined under consideration of the heat expansion coefficient of the platinum wire to be wound around the valleys of the ridges. The pitch of the valleys can also be varied depending on the number of the openings 16 formed in the frame 10. As the number of the openings 16 is increased, the pitch of the valleys may be reduced.

A method of winding the platinum wire around the frame 10 will now be described with reference to Figs. 4 to 11.

Fig. 4 is a perspective view of the frame of Figs. 2 and 3, around which the platinum wire acting as a first electrode is partially wound, illustrating a process for winding the platinum wire around the frame. Figs. 5 to 7 are perspective views of the frame of Figs. 2 and 3, around which the platinum wire acting as the first electrode is completely wound. Fig. 8 is a perspective view of the frame, around which another platinum wire acting as a second electrode is partially wound, illustrating a process for winding the platinum wire acting as the second electrode around

the frame completely wound with the platinum wire for the first electrode as shown in Fig. 7. Fig. 9 is a perspective view of the in-water discharging core according to the embodiment of the present invention, wherein the platinum wires acting as the first and second electrodes are wound around the frame by the processes of Figs. 5 to 8. Fig. 10 is a cross-sectional view of the in-water discharging core taken along line A-A of Fig. 9. Fig. 11 is a cross-sectional view of the in-water discharging core taken along line B-B of Fig. 9.

First, as shown in Fig. 4, a first platinum wire 20 acting as the first electrode is inserted into the aperture 12F formed at the first side 12 of the frame 10 and drawn out through the aperture 12E on the surface of the first side facing in the direction opposite to the leg 11B. Then, the first platinum wire 20 drawn out from the aperture 12E is inserted again into the aperture 12F and drawn out again through the aperture 12E. As such, the first platinum wire 20 is wound at least twice between the apertures 12F and 12E such that one end of the first platinum wire 20 is fixed thereto so as to provide a start portion of the first platinum wire 20, which will be tied with an end portion 20A of the first platinum wire 20 as shown in Fig. 7.

Then, while being maintained tightly inside the elongated groove 13C, the first platinum wire 20 is extended to the protrusion 13B along the elongated groove 13C formed on the second side 13, and wound at least once around the protrusion 13B. As such, since the first platinum wire 20 is wound at least once around the protrusion 13B, the first platinum wire 20 is fixed in a tight state along the elongated groove 13C.

Subsequently, while being maintained tightly, the first platinum wire 20 is extended along the valley formed between the outermost ridge 13A formed on one end of the upper surface of the second side 13 and the third side 14, the valleys formed between the outermost ridges 18A formed on the upper surfaces of the

plurality of compartments 18 and the third side 14, the valley formed between the outermost ridge 15A formed on one end of the upper surface of the fourth side 15 and the third side 14, the valley formed between the outermost ridge 15B formed on one end of the lower surface of the fourth side 15 and the third side 14, the valleys formed between the outermost ridges 18B formed on the lower surfaces of the plurality of compartments 18 and the third side 14, and the valley formed between the outermost ridge 13D formed on one end of the lower surface of the second side 13 and the third side 14.

Then, as shown in Figs. 4 and 5, while being maintained tightly, the first platinum wire 20 is extended along the next valley formed on the upper surface of the second side 13, the next valleys formed on the upper surfaces of the plurality of compartments 18, the next valley on the upper surface of the fourth side 14, the next valley formed on the lower surface of the fourth side 14, the next valleys formed on the lower surfaces of the plurality of compartments 18, and the next valley on one end of the lower surface of the second side 13. In such a manner, while being maintained tightly, the first platinum wire 20 is wound around the frame 10 along the last valleys formed between the first side 12 and the ridges of the second side 13, compartments 18 and fourth side 15.

Then, as shown in Fig. 6, the first platinum wire 20 is wound at least once around the mushroom-shaped protrusion 12C formed on the first side 12. As such, as the first platinum wire 20 is wound at least twice around the protrusion 12C, the first platinum wire 20 is fixed tightly.

Subsequently, The first platinum wire 20 is drawn out through the aperture 12E to provide the end portion 20A. The end portion 20A of the first platinum wire 20 drawn out through the aperture 12E is tied with the starting portion of the first platinum wire 20.

As such, when the first platinum wire 20 is wound around the frame 10, it is subsequently fixed at the apertures 12E and 12F, the protrusion 13B, the groove 13C and the mushroom-shaped protrusion 12F so that the entirety of the first platinum wire 20 can be tightly maintained.

Next, as shown in Fig. 8, a second platinum wire 22 acting as the second electrode is inserted into the aperture 12D formed at the first side 12 of the frame 10 and drawn out through the aperture 12G from the surface of the first side facing in the direction opposite to the leg 11A. The second platinum wire 22 drawn out from the aperture 12G is inserted again into the aperture 12D and is then drawn out again through the aperture 12G. The second platinum wire 22 is wound at least twice between the apertures 12D and 12G such that one end of the second platinum wire 22 is fixed thereto so as to provide an starting portion of the platinum wire 22 as shown in Fig. 9. Then, while being maintained tightly inside the elongated groove 12H, the second platinum wire 22 is extended to the protrusion 12J along the elongated groove 12H formed on the first side 12, and wound at least twice around the protrusion 12J. Subsequently, while being maintained tightly, the second platinum wire 22 is extended through the first valley formed between the outermost ridge 12A and the next ridge 12A formed on one end of the upper surface of the first side 12, the first valleys formed between the outermost ridges 17A and the second ridges 17A formed on the upper surfaces of the plurality of compartments 17, the first valley formed between the outermost ridge 14A and the second ridge 14A formed on one end of the upper surface of the third side 14, the first valley formed between the outermost ridge 14B and the second ridge 14B formed on one end of the lower surface of the third side 14, the first valleys formed between the outermost ridges 17B and the second ridges 17B formed on the lower surfaces of the plurality of compartments 17, and the first valley formed between the

outermost ridge 12I and the second ridge 12I formed on one end of the lower surface of the first side 12.

Then, as shown in Figs. 8 and 9, while being maintained tightly, the second platinum wire 22 is extended along the next valley on the upper surface of the first side 12, the next valleys formed on the upper surfaces of the plurality of compartments 17, the next valley on the upper surface of the third side 14, the next valley formed on the lower surface of the third side 13, the next valleys formed on the lower surfaces of the plurality of compartments 17, and the next valley on one end of the lower surface of the first side 12. In such a manner, while being maintained tightly, the second platinum wire 22 is wound around the frame 10 to the last valleys on the first side 12, the compartments 17 and third side 13.

Then, as shown in Fig. 9, after the second platinum wire 22 is wound at least once around the mushroom-shaped protrusion 12B formed on the first side 12, it is drawn out through the aperture 12G of the first side 12. The end portion 22A of the platinum wire drawn out through the aperture 12G is tied with the starting portion of the second platinum wire 22.

As such, when the second platinum wire 22 is wound around the frame 10, it is subsequently fixed at the apertures 12D and 12G, the protrusion 12J, the groove 12H and the mushroom-shaped protrusion 12B so that the entirety of the second platinum wire 22 can be tightly maintained.

Thus, as shown in Figs. 10 and 11, the first platinum wire 20 and the second platinum wire 22 are uniformly spaced (by a predetermined distance between about 0. 5-1. 5 mm) apart from each other. The first platinum wire 20 is maintained tightly by the apertures 12E and 12F, the protrusion 13B, the groove 13C and the mushroom-shaped protrusion 12F, while the second platinum wire 22 is maintained tightly by the apertures 12D and 12G, the protrusion 12J, the groove 12H and the mushroom-shaped protrusion

12B. Further, both the first platinum wire 20 and the second platinum wire 22 are prevented from being loosened by the valleys between the ridges 17A and 17B; 18A and 18B formed on the vertical and horizontal compartments 17 and 18, respectively. Thus, uniform tension can be applied to the platinum wires when winding the platinum wires around the frame, and at the same time, even though the platinum wire is expanded due to an increase in temperature of water during operation of the in-water discharging core, the short circuit of the first and second platinum wires 20 and 22 can be prevented.

Preferably, the distance between the first platinum wire 20 and the second platinum wire 22 is maintained with a predetermined distance selected between about 0. 5-1. 5 mm, and it is desirable that this distance is selected depending on the heat expansion coefficient of the platinum wires 20 and 22 and on distances between the compartments 17 and 17 ; 18 and 18 defining the openings 16. As the distances between the compartments 17 and 17; 18 and 18 are reduced, it is possible to reduce the distance between the first platinum wire 20 and the second platinum wire 22. As the distance between the first platinum wire 20 and the second platinum wire 22 is reduced, there is provided an advantageous effect of enabling low-power in-water discharging. It is desirable that the first and second platinum wires 20 and 22 have a thickness of 0. 1-1 mm.

Meanwhile, the structure of the frame for the in-water discharging core according to the present invention can be embodied with various modifications as well as the shape shown in Fig. 2, and an example thereof is shown in Fig. 12.

In the in-water discharging core 100 structured as described above, the first platinum wire 20 is arranged on a coplanar plane by a predetermined distance (x) to each other and the second platinum wire 22 is arranged on another coplanar plane with a predetermined distance (y) to each other, as shown in Fig. 14.

The in-water discharging occurs at numerous points A (that is, virtual mesh-shaped points) where the first and second platinum wires 20 and 22 overlap each other with a predetermined height h. Specifically, the points A are spaced apart from each other in the horizontal direction by x and in the lengthwise direction by y, each having predetermined distances between 0. 5-1 mm, and each of the points is formed with the first and second platinum wires 20 and 22 such that a vertical distance between the first and second platinum wires 20 and 22 is denoted by h of a predetermined distance selected from between 0. 5 ~ 1. 5 mm.

As described above, the in-water discharging core of the present invention can completely overcome the problem of the possibility of loosening the tension of the platinum wires, which can occur during the winding steps of the platinum wire for each side and during the finishing step for a power supply lead line.

Thus, if the platinum wires are wound uniformly with a certain tension, the in-water discharging core can be provided with uniform quality.

A sterilizing water generator according to the present invention will now be described in detail with reference to Figs.

15 and 17.

Fig. 5 is a schematic diagram of a sterilizing water generator according to an embodiment of the present invention.

Including the in-water discharging core 100 shown in Fig.

1 and the power supply 40 for supplying power of opposite polarities to the first platinum wire 20 and the second platinum wire 22, respectively, of the in-water discharging core 100, the sterilizing water generator of the present invention further comprises a barrel member 30 containing the water. Here, the points, where the first platinum wire 20 and the second platinum wire 22 overlap each other, respectively constitute in-water discharging cells as switches, in which the water itself acts as a switching media, and the first and second platinum wires 20 and

22 act as cathodes and anodes. When a voltage above a predetermined limit is applied to the switches, the switches used in the above system, that is, the in-water discharging cells conduct a self-switching operation and are broken down due to the breakdown mechanism of the water. As the in-water discharging cells conduct the self-switching operation, a conduction channel is formed between the cathode and the anode. Subsequently, when the voltage between the cathode and the anode of the in-water discharging cells is 0 V, the water in the barrel fills the path between the cathode and the anode, so that a voltage is applied between the anodes and the cathodes (that is,"self-recovery process of the water"). With the self-switching operation and the self-recovery process of the water repeated, the in-water discharging occurs continuously, thereby effectively generating the anions.

In such a construction, when the power is supplied to the first and second platinum wires 10 and 22 of the in-water discharging core 100, if a positive voltage is applied only to one of the wires and a negative voltage is applied only to the other, impurities ionized into anions adhere to the side to which the positive voltage is applied, thereby remarkably reducing efficiency of the in-water discharging core 100. In order to solve this problem, the positive voltage (+V) and the negative voltage (-V) are alternately supplied to the sterilizing water generator from the power supply 40 with a period of time of 0. 5 ~ 5 minutes as shown in Figs. 16a and 16b, such that the voltages with opposite polarities are applied to the first platinum wire 20 and the second platinum wire 22, respectively, at the same point of time. That is, the voltage shown in Fig. 16a is applied to the first platinum wire 20, and the voltage shown in Fig. 16b is applied to the second platinum wire 22. Thus, the impurities ionized with the negative polarity shift from the mesh-shaped points biased with the positive voltage to the mesh-shaped points biased with the

negative voltage, thereby preventing the reduction in efficiency of the in-water discharging core 100, which can occur when the impurities adhere only to one electrode.

By this, the ionized impurities are adhered to the virtual mesh-shaped points A of fig. 14 (SW of Fig. 16) in the in-water discharging core 100, forming the nucleation sites. The nucleation sites become localized electric field enhancement regions. Thus, a localized high electric field density is provided, so that local heating is performed to evaporate water molecules, forming bubbles. Once the bubbles are formed, the bubbles are expanded so that the conduction channel is formed between the cathode (+) electrode and the anode (-) electrode.

This is the in-water discharging due to the bubble mechanism. When the in-water discharging occurs, the water molecule is subjected to a chemical reaction as follows.

H2O + E # H, O <BR> <BR> <BR> <BR> <BR> O + O # O2<BR> H # H+ O2 # O2- H+, O2 + H2O # H2O2 (evaporation), OH (dissolved in water) Here, E is electric energy of the electric field applied to H20.

The generated anions are oxidized by heavy metals dissolved in the water and the ionized impurities, activating the impurities.

As to microbes in the water, such as viruses, bacteria and the like, since H+, acting to protect cell membranes of the microbe, is coupled to OH-to produce H2O, so that removal of hydrogen destroys the cell membranes, thereby sterilizing every kind of microbe.

Depending on the intended use of the water activated by the in-water discharging core 100, a method for treating active oxygen produced by the in-water discharging core 100 can be varied. If

the water is to be used in sterilization and insecticide, the water containing the active oxygen produced by the in-water discharging core 100 can be directly used as sterilizing water for that purpose.

That is, since the sterilizing water contains the anions as described above, not only can it sterilize viruses or bacterium remaining on vegetables, fruits, greens and dinner sets, but it can also activate the heavy metals and detrimental compounds on the vegetables, the fruits, the greens and the dinner sets through oxidation.

Fig. 17 is a schematic diagram of a sterilizing water generator according to another embodiment of the present invention. As shown in Fig. 17, including the in-water discharging core 100, a sterilizing water generator 300 of the present invention further comprises a barrel member 210, a base 220 and a power supply/control means (not shown).

The barrel member 210 is filled with water and mounted with the base 220 at one portion inside the barrel member 20. The base 220 is made of an insulating material, and previously subjected to treatment to water-proof its surface. With the legs fixed to the base 220, the in-water discharging core 100 stands upright on the base 220, such that the in-water discharging core 100 is perpendicular, or has a predetermined angle (e. g. 45 °), to the direction of the water flow. One or more in-water discharging cores 100 may be provided for the sterilizing water generator according to its capacity. When a plurality of in-water discharging cores 100 are provided on the base, these can be arranged in line or staggered in left and right directions on the base. The first and second platinum wires of the in-water discharging core 100 are drawn out from the bottom surface of the base, and supplied with direct current power having opposite polarities from the power supply/control means. Here, the base 220 is previously subjected to the treatment to water-proof its lower surface for preventing the water from permeating there

through.

The barrel member 210 may be a water container for containing the water or a water pipe through which the water flows. The barrel member 210 may be provided with a temperature sensor for detecting a temperature of the water. The barrel member 210 may be further provided with a means for controlling in-flow or out-flow of the water according to the power supply/control means, by which when the temperature detected by the temperature sensor is over a predetermined temperature, the water in the barrel member 210 flows out and new water flows to the barrel member 210. In this case, overheating of the in-water discharging core 100 can be prevented by a water-cooling method.

In order to further increase the capacity of the sterilizing water generator, as shown in Fig. 17, the base 220 provided with the plurality of in-water discharging cores 100 may be mounted not only on a lower side of the barrel member 210, but also on an upper side of the barrel member 210 at the same time such that the upper and lower bases face each other. In this case, without increasing the volume of the sterilizing water generator, the capacity of the sterilizing water generator can be doubled.

Next, a sterilizing water supply system according to the present invention will now be described in detail with reference to Fig. 18.

Fig. 18 is a schematic diagram of a sterilizing water supply system according to an embodiment of the present invention.

As shown in Fig. 18, the sterilizing water supply system of the present invention comprises: a sterilizing water generator 200 provided with at least one in-water discharging core 100 for in-water discharging, thereby making water inside thereof sterilized; a water tank 800 for containing the sterilizing water produced by the sterilizing water generator 200; a filter 400 for removing impurities in the water to be supplied to the sterilizing water generator 200; and a power supply/control means 600 for

supplying and controlling power to the in-water discharging core 100.

The system is further provided with water supply pipes LI and L2 for supplying the water in the water tank 800, and a pump 300 equipped between the filter 400 and the sterilizing water generator 200 for supplying the water to the sterilizing water generator 200.

Between the water supply pipes LI and L2, a solenoid valve 500 for controlling the supply of the water with the power supply/control means 600 is equipped. Between water supply pipes L5 and L6 arranged between the sterilizing water generator 200 and the water tank 800, a check valve for forcing the water to flow in one direction is equipped.

The sterilizing water generator 200 is equipped with a temperature sensor 250 therein. Depending on the temperature detected by the temperature sensor 250, the power supply/control means 600 controls the pump 300 and the solenoid valve 500, allowing the water to flow, so that overheating of the in-water discharging core 100 can be prevented. That is, when the temperature of the in-water discharging core 100 increases above a preset temperature, the power supply of the in-water discharging core 100 is cut-off, thereby preventing breakdown of the in-water discharging core 100.

The water tank 800 is provided with a water supply pipe L7 for supplying the water from the exterior of the water tank through a solenoid valve 840 controlled by the power supply/control means 600, and a water volume sensor 850 for detecting the volume of the water in the water tank 800. The power supply/control means 600 controls the solenoid valve 840 such that the water can be supplied to the water tank 840 through the solenoid valve 840 according to the water volume detected by the water volume sensor 850. Here, the power supply/control means 600 controls the pump 300 and the solenoid valve 840 according to the water volume

detected by the water volume sensor 850, such that the water can be circulated from the water tank 800, through the water supply pipe LI, solenoid valve 500, water supply pipe L2, filter 400, pump 300, sterilizing water generator 200, sterilizing water supply pipe L5, check valve 700 and sterilizing water supply pipe L6 to the water tank 800.

Meanwhile, according to the present invention, the water can be supplied from the exterior through an exterior water supply solenoid valve, which can be controlled by the power supply/control means 600, between the solenoid valve 500 and the filter 400, not by the structure wherein the water is supplied from the exterior to the water tank 800. In this case, the power supply/control means 600 controls the pump 300 and the solenoid valve according to the water volume detected by the water volume sensor 850, such that the water can be supplied from the exterior through the filter 400, pump 300 and sterilizing water generator 200 to the water tank 800. At this point, preferably, the power supply/control means 600 is adapted such that the water is not supplied to the filter 400 through the solenoid valve 500. Then, the power supply/control means 600 stops the supply of the water from the exterior through the exterior water supply solenoid valve according to the water volume detected by the water volume sensor 850. The power supply/control means 600 controls the pump 300 and the solenoid valve 500, so that the water can circulate from the water tank 800 through the filter 400, pump 300 and sterilizing water generator 200 to the water tank 800.

Meanwhile, it is desirable that the circulation of the water from the water tank 800 through the filter 400, pump 300 and sterilizing water generator 200 to the water tank 800, and operation of the in-water discharging core 100 are repetitively carried out with a predetermined period of time.

The water tank 800 is provided with a gas outlet 820 for guiding a gas contained in the sterilizing water to the exterior,

a sterilizing water discharge pipe 810 and a valve 830 for discharging the sterilizing water to the exterior.

Preferably, the power supply/control means 600 alternately applies a positive (+) voltage and a negative (-) voltage to the first and second platinum wires of the in-water discharging core, respectively, with a predetermined period of time. The predetermined period of time is preferably in the range of 0.5 - 5 minutes.

An in-water discharging core according to another embodiment of the invention will now be described in detail with reference to Figs. 19 to 25.

Fig. 19 is a perspective view of the in-water discharging core according to still another embodiment of the present invention. The in-water discharging core according to the embodiment of the present invention is structured such that a first electrode frame 40 and a second electrode frame 50 are fixed on a base member 60 with a predetermined distance to each other.

As shown in Fig. 20, the first electrode frame 40 of the in-water discharging core comprises a square-shaped frame body formed with first to fourth sides 41 to 44 to define an opening at the center of the frame body, and legs 45 and 46 at opposite sides of the frame body. The first electrode frame 40 is made of an insulating material, such as polycarbonate.

In the first electrode frame 40, the first and second sides 41 and 42 are respectively connected to opposite sides of the third and fourth sides 43 and 44, along which a platinum wire 47 is repetitively wound around the first electrode frame 40 in the direction of the X-axis with a predetermined distance. In order to guide the platinum wire 47 such that the platinum wire 47 is wound in the direction of the X-axis with the predetermined distance and maintained in its wound state, the third and fourth sides 43 and 44 are formed with front ridges 43A and 44A and with rear ridges 43B and 44B, respectively, along the lengthwise

direction of the third and fourth sides 43 and 44 with the predetermined distance.

The front ridges 43A and 44A and the rear ridges 43B and 44B formed on the front and rear surfaces of the third and fourth sides 43 and 44 along the vertical direction thereof allow the platinum wire 47 to be wound along valleys formed between the ridges. In order to make the platinum wire 47 gradually wind in the direction of the X-axis with the predetermined distance while allowing the platinum wire 47 wound along the front side and the platinum wire 47 wound along the rear side thereof to be spaced apart by a predetermined height from each other, the front ridges 43A and 44A and the rear ridges 43B and 44B are formed on the front and rear surfaces of the third and fourth sides, respectively, such that each of the front ridges 43A and 44A is formed at portion slightly deviated from a portion where each of the rear ridges 43B and 44B is formed, thereby providing a predetermined height between tips of the front and rear ridges.

Meanwhile, the valleys formed on the front ridges 43A and 44A and on the rear ridges 43B and 44B, respectively, are preferably formed with a pitch of about 0. 5 ~ 1. 5 mm, respectively, and the pitch of the valleys must be determined under consideration of the heat expansion coefficient of the platinum wire 47 to be wound around the valleys of the ridges. The height difference between the front ridges 43A and 44A and the rear ridges 43B and 44B is preferably in the range of about 0. 5-1. 5 mm, under consideration of the heat expansion coefficient of the platinum wire 47 to be wound around the valleys of the ridges.

The first electrode frame 40 is provided with the legs 45 and 46 at lower portions of the opposite sides thereof, respectively. Each of the legs 45 and 46 is formed with a fastening protrusion 45A (46A) for fixing the first electrode frame 40 to the base member 60.

Fig. 21 is a perspective view illustrating a process for

winding a second platinum wire around the second electrode frame according to another embodiment of the present invention. As shown in Fig. 21, the second electrode frame 50 comprises a square-shaped frame body formed with first to fourth sides 51 to 54 to provide an opening at the center of the frame body, and legs 55 and 56 at opposite sides of the frame body. It is made of an insulating material, such as polycarbonate.

In the second electrode frame 50, first and second sides 51 and 52 are respectively connected to opposite sides of third and fourth sides 53 and 54. Along the first and second sides 51 and 52, a platinum wire 57 is repetitively wound around the first electrode frame 50 in the direction of the Y-axis with a predetermined distance. In order to guide the platinum wire 57 such that the platinum wire 57 is wound in the direction of the Y-axis with the predetermined distance while being maintained in its wound state, the first and second sides 51 and 52 are formed with front ridges 51A and 52A and with rear ridges 51B and 52B, respectively, along the width of the first and second sides 51 and 52 with the predetermined distance.

The front ridges 51A and 52A and the rear ridges 51B formed on the front and rear surfaces of the first and second sides 51 and 52 along the lengthwise direction thereof allow the platinum wire 57 to be wound through valleys formed between the ridges.

In order to make the platinum wire 57 gradually wind with a predetermined distance in the direction of the Y-axis while allowing the platinum wire 57 wound along the front side and the platinum wire 57 wound along the rear side to be spaced apart by a predetermined height from each other, the front ridges 51A and 52A and the rear ridges 51B and 52B are formed on the front and rear surfaces of the first and second sides such that each of the front ridges 51A and 52A is formed at a portion slightly deviated from a portion where each of the rear ridges 51B and 52B is formed, thereby providing a predetermined width between tips of the front

and rear ridges.

Meanwhile, the valleys formed by the front ridges 51A and 52A and the rear ridges 51B and 52B, respectively, are preferably formed with a pitch of about 0. 5 ~ 1. 5 mm, respectively, and the pitch of the valleys must be determined under consideration of the heat expansion coefficient of the platinum wire 57 to be wound around the valleys of the ridges. The height difference between the front ridges 51A and 52A and the rear ridges 51B and 52B is preferably in the range of about 0. 5-1. 5 mm, under consideration of the heat expansion coefficient of the platinum wire 57 to be wound around the valleys of the ridges.

The second electrode frame 50 is provided with the legs 55 and 56 at lower portions of the opposite sides thereof, respectively. Each of the legs 55 and 56 is formed with a fastening protrusion 55A (56A) for fixing the second electrode frame 50 to the base member 60.

Fig. 22 is an exploded perspective view illustrating the state of the first and second electrode frames according to the embodiment of Fig. 21 mounted to the base member. As shown in Fig. 22, the base member 60 is formed with insertion holes 61 and 62 at opposite sides of one end of the base member 60 for fixing the first electrode frame 40 to the base, and with distance adjustment members comprising guide grooves 63 and 65 and latch recesses 64 and 66 on both sides of the base member 60 along the lengthwise direction thereof. The guide grooves 63 and 65 and the latch recesses 64 and 66 of the distance adjustment members enable the second electrode frame 50 to be freely adjusted in terms of its distance to the first electrode frame 40, and to be fixedly coupled to the base member according to a predetermined distance finally determined.

When the legs 45 and 46 are inserted into the insertion holes 61 and 62 formed at opposite sides of one end of the base member 60, the fastening protrusions 45A and 46A formed around the legs

act to fix the first electrode frame 40 so that it is not released from the base member 60, so that the first electrode frame 40 is fixed to the base member 60.

Here, the guide grooves 63 and 65 of the distance adjustment member formed on the base member 60 guide the second electrode frame 50 such that the second electrode frame 50 can be slidably moved in the lengthwise direction of the base member 60 in the state that the fastening protrusions 55A and 56A formed around the legs of the second electrode frame 50 are latched to the distance adjustment member. As the distance of the second electrode frame 50 to the first electrode frame 40 fixedly mounted on the end of the base member 60 is finally determined, the second electrode frame 50 is fixed to the base member 60 by latching the fastening protrusions 55A and 56A formed around the legs to the latch recess, corresponding to the finally determined distance, among the plurality of latch recesses 64 and 66 formed along the guide grooves 63.

Fig. 23 is a diagram illustrating the state of the first and second electrode frames according to the embodiment of fig. 21 alternately mounted in an array along the base member. According to Fig. 23, along the base member 60, formed to have a sufficient length, a plurality of first electrode frames wound with the platinum wire in the direction of the X-axis and a plurality of second electrode frames wound with the platinum wire in the direction of the Y-axis are alternately arranged in an array and fixed on the base member by a predetermined distance from each other.

The plurality of first electrode frames 40-1 to 40-n and the plurality of second electrode frames 50-1 to 50-n alternately arranged in an array on the base member 60 are preferably provided at a location where the pollution level of water is severe or the capacity for generating the sterilizing water must be doubled, for example, a sewage disposal plant and the like.

Fig. 24 is a representation depicting a relationship between electrolytic properties of water and the distance between the first and second electrode frames mounted on the base member according to the embodiment of Fig. 21. As shown in Fig. 24, the first electrode frame 40 wound with the platinum wire in the direction of the X-axis is fixedly mounted on the base member 60, and the second electrode frame 40 wound with the platinum wire in the direction of the Y-axis is mounted on the base member 60 to have the predetermined distance to the mounting position of the first electrode frame 40. The first electrode frame 40 wound with the platinum wire in the direction of the X-axis and the second electrode frame 50 wound with the platinum wire in the direction of the Y-axis constitute multi-point diodes using water as the media, which are formed with multiple line electrodes in the direction of the X-axis and in the direction of the Y-axis, respectively. The number of the diodes is equal to the number of virtual cross points, which the line wound in the direction of the X-axis and the line wound in the direction of the Y-axis constitute using water as the media.

Further, in the state that the first and second electrode frames 40 and 50 mounted with a predetermined distance L from each other, when a predetermined voltage V is applied to the first electrode frame 40 in the state that the second electrode frame 50 is grounded, plasma discharge is induced due to weak electrolysis property of water, analyzing the water molecules (H20).

Here, the distance L between the first and second electrode frames 40 and 50 is determined according to an electrolyzed amount of the water. Thus, when the electrolysis degree of the water is high, the distance between the second electrode frame and the first electrode frame 40 is increased. When the electrolysis degree of the water is low, the distance between the second electrode frame 50 and the first electrode frame 40 is decreased.

Meanwhile, a plasma discharge voltage property of the multi point diodes formed by the platinum wire of the first electrode frame 40 wound in the direction of the X-axis and the platinum wire of the second electrode frame 50 wound in the direction of the Y-axis is exhibited as shown in Fig. 25. As shown in Fig.

25, when a bias voltage V is applied to the first electrode frame 40, with the passage of time (t in Fig. 25), the water itself acts as the switching media, and the platinum wires of the first and second electrode frames 40 and 50 act as the cathodes and anodes.

Thus, at points to which a voltage of a predetermined limit or more is applied, the self-switching operation is proceeded by the breakdown mechanism of the water and the voltage between the cathodes and the anodes is 0 V. Then, the water fills the path between the cathodes and the anodes, generating the plasma discharge and the self-recovery process of the water wherein the voltage is generated between the anodes and the cathodes by the self-switching operation. Thus, with the voltage having the predetermined limit, the process for continuously causing the in-water discharge is repeated, thereby effectively generating the active oxygen and ozone.

With reference to Figs. 26 to 29, yet another embodiment of the present invention will now be described in detail.

Fig. 26 is a perspective view of an in-water discharge core according to yet another embodiment of the present invention. As shown in Fig. 26, the in-water discharge core according to the embodiment of the present invention comprises first and second protrusion stripe plates 70 and 80, each of which are plated with electrically conductive platinum, and a base member 90 on which the first and second protrusion stripe plates 70 and 80 are fixedly mounted a predetermined distance from each other.

In the in-water discharge core, the first protrusion stripe plate 70 comprises a square shaped plate 71. The plate 71 is provided with front and rear protrusion stripes 72 and 73

respectively protruded on front and rear surfaces thereof in the direction of the X-axis such that the front and rear protrusion stripes 72 and 73 correspond to each other, and with slots 76 adapted to allow water to flow between the protrusion stripes.

The plate is made of titanium and entirely plated with the electrically conductive platinum.

The first protrusion stripe plate 70 further comprises legs 74 and 75 at lower portions of the opposite sides thereof, respectively. Each of the legs 74 and 75 is formed with a fastening protrusion 74A (75A) for fixedly mounting the first protrusion stripe plate 70 to the base member 90.

Fig. 28 is a diagram illustrating the second protrusion stripe plate according to the embodiment of the present invention.

The second protrusion stripe plate 80 comprises a square shaped plate 81, which is provided with front and rear protrusion stripes 82 and 83 respectively protruded on front and rear surfaces thereof in the direction of the Y-axis such that the front and rear protrusion stripes 82 and 83 correspond to each other, and with slots 86 adapted to allow water to flow between the protrusion stripes. The plate is made of titanium and entirely plated with electrically conductive platinum or gold.

The second protrusion stripe plate 80 is further provided with legs 84 and 85 at lower portions of the opposite sides thereof, respectively. Each of the legs 84 and 85 is formed with a fastening protrusion 84A (85A) for fixedly mounting the first protrusion stripe plate 80 to the base member 90.

Fig. 29 is an exploded perspective view illustrating the state of the first and second protrusion stripe plates according to the present invention mounted on the base member. As shown in Fig. 29, the base member 90 is formed with insertion holes 91 and 92 at opposite sides of one end of the base member 90 for fixing the first protrusion stripe plate 70 to the base member, and with distance adjustment members comprising guide grooves 93 and 95

and latch recesses 94 and 96 on both sides of the base member 90 along the lengthwise direction thereof. The guide grooves 93 and 95 and the latch recesses 94 and 96 of the distance adjustment members allow the'distance between the second protrusion stripe plate 80 and the first protrusion stripe plate 70 to be freely adjusted, and to be fixedly coupled to the base member according to a predetermined distance.

When the legs 74 and 75 of the first protrusion stripe plate 70 are inserted into the insertion holes 91 and 92 formed at opposite sides of one end of the base member 90, the fastening protrusions 75A and 75A, formed around the legs, act to fix the first protrusion stripe plate 70 so that it is not released from the base member 90, so that the first protrusion stripe plate 70 is fixed to the base member 90.

Here, the guide grooves 93 and 95 of the distance adjustment member formed on the base member 90 guide the second protrusion stripe plate 80 such that the second protrusion stripe plate 80 can be moved in the lengthwise direction of the base member 90 in the state that the fastening protrusions 84A and 85A formed around the legs 84 and 85 of the second protrusion stripe plate 80 are latched to the distance adjustment member. As the distance of the second protrusion stripe plate 80 to the first protrusion stripe plate 70 fixedly mounted on the end of the base member 90 is finally determined, the second protrusion stripe plate 80 is fixed to the base member 90 by latching the fastening protrusion 84A and 85A to the latch recess, corresponding to the finally determined distance, among the plurality of latch recesses 94 and 96 formed along the guide grooves 93.

Meanwhile, the first and second protrusion stripe plates 70 and 80 are structured such that when a predetermined bias voltage is applied to one of the plates in the state that the other plate is grounded, the plasma discharge is induced due to a low electrolyzed amount of the water and analyzes the water molecules

(H2O). The first and second protrusion stripe plates 70 and 80 are adapted to adjust the distance between the ridges according to an electrolyzed amount of the water.

Further, a plurality of first and second protrusion stripe plates 70 and 80 may be alternately arranged in an array on the base member.

It should be understood that the embodiments and the accompanying drawings as described above have been described for illustrative purposes and the present invention is limited by the following claims. Further, those skilled in the art will appreciate that various modifications, additions and substitutions are allowed without departing from the scope and spirit of the invention as set forth in the accompanying claims.
