BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

The present invention relates to a water dispenser constructed in such way as to enable dispensation of cold water(drinking water) stored in a refrigerator at an external side of the refrigerator without opening and closing a door thereof, and more particularly to a water dispenser of a refrigerator for utilizing a plurality of magnetic members or magnetization means to open a valve plate disposed underneath a storage vessel, so that cold magnetized water good for user's health can be supplied.

DESCRIPTION OF THE PRIOR ART

A typically-used water dispenser of a refrigerator is constructed, as illustrated in Figure 1, to dispense cold water stored in the refrigerator at an external side of a refrigerator body 1, to which a freezing chamber door 2 and a refrigerating chamber door 3 are coupled by a hinge (not shown)in such way as to allow the doors 2 and 3 to be opened and closed freely.

The refrigerating chamber door 3 is disposed at one side thereof with a water dispenser 4.

As illustrated in Figure 2, the water dispenser 4 is releasably disposed at an inner side of the refrigerating chamber door 3 with

a water storage vessel 9 where cold water (w) is stored.

Furthermore, the water storage vessel 9 is disposed at an upper side thereof with a lid 10 in such way as to allow same to be opened and closed, and mounted at a lower side thereof with a lower cap 11.

The lower cap 11 is resiliently provided at an inner side thereof with a valve body 12 by a spring 8b so as to be vertically moved by a slide member 7.

The valve body 12 is arranged at an upper end thereof with a valve plate 13 for controlling flow of the cold water(w) by opening and closing an upper end of the lower cap 11 according to the vertical movement of the valve body 12.

Meanwhile, the refrigerating chamber door 3 is formed at an inner side thereof with a water discharge outlet 5a to allow the cold water(w) to be discharged out of the water storage vessel 9, and lengthwise and piercingly disposed at an upper side thereof with a cylinder 5 formed with a mounting part 5b thereon.

The cylinder 5 is provided therein with the slide member 7 resiliently disposed by a spring 8, where the slide member 7 is connected to a rod 7a and horizontally and sliding operated by operation of a water discharge lever 6 hingedly coupled to a front side thereof.

The mounting part 5b is mounted therein with the water storage vessel 9.

Now, operational relation of the water dispenser of the conventional refrigerator thus constructed will be described.

First of all, when the water storage vessel 9 where a predetermined quantity of cold water (w) is stored is placed in the mounting part 5b formed at an upper side of the cylinder 5, the valve body 12 coupled to an inner side of the lower cap 11 is lifted downward at a lower end thereof by elastic force of the spring 8a to thereby cause the valve plate 13 to close an upper end of the lower cap 11, so that the cold water (w) in the water storage vessel 9 can maintain a state of not being discharged, as illustrated in Figure 2.

When a vessel (c) such as cup and the like is placed underneath the water discharge outlet 5a as illustrated in Figure 2 in an alternate long and short dash line, and when the vessel (c) is pushed toward an arrow direction, the water discharge lever 6 is forwardly moved.

According to the forward operation of the water discharge lever 6, the slide member 7 connected to the rod 7a is backwardly moved and at the same time, the valve body 12 is upwardly operated.

Accordingly, the valve plate 13 coupled to the upper end of the valve body 12 is lifted upward to thereby open an upper end of the lower cap 11, so that the cold water (w) can be discharged into the vessel (c) through the lower cap 11, cylinder 5 and through the water discharge outlet 5a.

However, there is a problem in the conventional water dispenser in that same is made by numerous parts, making it difficult to be assembled and thereby increasing manufacturing cost.

There is another problem in that a cylinder and a slide member have to be separated for cleaning thereof, thereby causing lots of inconveniences.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Fig. 3 is an assembled sectional view of a water dispenser of a refrigerator according to a first embodiment of the present invention.

Reference number 15 in Figure 3 is a cylinder for being pierced through one side of the refrigerating chamber door 3 to be mounted tightly and insertedly thereat, and the cylinder 15 is formed at a tip end thereof with a water discharge outlet 32a for discharging cold water (W).

The cylinder 15 is resiliently disposed therein with a slide member 17 by a resilient member 18, and the slide member 17 is resiliently contacted at a tip end thereof to an inner side of a water discharge lever 26a hinge-coupled to a front surface of the refrigerating chamber door 3 for being rotated.

The slide member 17 is fixedly provided with a first valve plate, 18a for selectively opening and closing an inner side of the cylinder 15 according to a slide operation caused by an operation of the water discharge lever 26a, where the first valve plate 18a is insertedly disposed at one side thereof with a first magnetic member 28.

Furthermore, the cylinder 15 is screwed at an inner end thereof by a plug 19 to allow the slide member 17 and the resilient member 18 to be separated therefrom.

Meanwhile, a mounting part 20b formed at an upper side of the cylinder 15 is releasably disposed with a water storage vessel 34

for storing a predetermined quantity of cold water (W) therein.

The water storage vessel 34 is formed at an upper side thereof with an air hole 30a for air ventilation and at the same time is coupled at a predetermined spacing to a lid 30 for separation therefrom through the medium of a filter member 32a.

The water storage vessel 34 is separably coupled at a lower side thereof to a lower cap 42a for being resiliently disposed with an 10 operational axis 40 vertically operated according to operation of the slide member 17.

The operational axis 40 is resiliently disposed through the medium of a resilient member 8a a t an inner side of the lower cap 15 42a.

The operational axis 40 is fixedly arranged at an upper side thereof with a second valve plate 18b for selectively opening and closing an upper end of the lower cap 42a to thereby allow the cold

20 water (W) in the water storage vessel 34 to flow into the lower cap

42a.

Furthermore, the operational axis 40 is fixedly mounted at a lower side thereof with a second magnetic member 42 for raising the 25 operational axis 40 by way of magnetic force generated from the first magnetic member 30.

The operational axis 40 is so constructed as to prevent a lower end thereof from protruding from a lower end tip of the lower cap

30 42a, and the first and second magnetic members 28 and 42 are so

constructed as to cause the operational axis 40 to be raised when magnetic poles of the same polarity approach.

Unexplained reference numeral 16 in the drawing indicates a cover plate coupled to a front surface of the refrigerating chamber door 3, and reference numeral 43a represents a packing member for preventing leakage of the cold water (W) by being disposed between the water storage vessel 34 and the lower cap 42a.

Reference numeral 46a defines another packing member for preventing leakage of the cold water (W).

Now, operational effect of the water dispenser of a refrigerator according to the first embodiment of the present invention thus constructed will be described.

First of all, a predetermined quantity of cold water (W) is stored in the water storage vessel 34 under a state where the lid

30 is separated. Then, the water storage vessel 34 combined by the lid 30 is mounted into the mounting part 20b formed at an upper side of the cylinder 15.

At this time, when a vessel (C) such as cup and the like is placed in the water discharge lever 26a and when force is applied thereto as illustrated in Figure 4, the slide member 17 serves to compress the resilient member 18 to thereafter be retreated, and at the same time, the first valve plate 18a is moved to open an inner side of the cylinder 15 and to raise the operational axis 40 resiliently disposed in an inner side of the lower cap 42a.

In other words, the first magnetic member 28 which slides along the retreat operation of the slide member 17 approaches a lower side of the second magnetic member 42, so that repulsive force is worked by the magnetic poles of the same polarity between the first and second magnetic members 28 and 42, where the operational axis 40 is raised up by the repulsive force.

Accordingly, the operational axis 40 serves to compress the resilient member 18 and is raised up, so that the second valve plate 18b is detached from an upper end of the lower up 42a to thereby allow the cold water (W) to be infused into the lower cap 42a.

The cold water (W) infused into the lower cap 42a is discharged into the vessel (C) through the cylinder 15 and the water discharge outlet 32a to thereby allow the cold water (W) to be dispensed.

At this time, the cold water (W) discharged into the water discharge outlet 32a is magnetized by the first and the second magnetic members 28 and 42 when same is infused into the lower cap 42a and the cylinder 15, thereby enabling to obtain hexagonal water having a hexagonal ring structure which is good for the human body.

Meanwhile, when the force applied to the water discharge lever 26 is released, the slide member 17 is forwardly moved by the elastic force of the resilient member 18, and simultaneously the first valve plate 18a serves to block an inner passage of the cylinder 15 to thereby be stop ped supply of the cold water (W).

Furthermore, the repulsive force generated by the magnetic force

from the first and the second magnetic members 28 and 42 is lost when same returns to an original state, as illustrated in Figure 3, and the operational axis 40 is lifted downward by the elastic force of the resilient member 8a.

Therefore, the second valve plate 18b serves to close an upper end of the lower cap 42a to thereby cause the cold water (W) in the water storage vessel 34 to be discharged no longer.

Accordingly, once the discharge of the cold water (W) is completed, the cold water (W) is avoided from being supplied into the cylinder 15 by the first valve plate 18a. The cold water (W) is also prevented from being supplied to the lower cap 42a by the second valve plate 18b, so that the force applied to the water discharge lever 26a is released and at the same time, discharge of the cold water (W) is stopped to thereby enable a minimized generation of residual water.

Furthermore, if the cold water (W) is to be supplemented in the water storage vessel 34, the vessel 34 is separated from the mounting part 20b and the lid 30 is separated, which enables replenishment of the cold water (W).

As mentioned in the foregoing, there is an advantage in the water dispenser of a refrigerator according to the first embodiment of the present invention, in that cold water can be selectively discharged from a water storage vessel by way of first and second magnetic members, thereby making same in a simpler structure than that of the conventional water dispenser.

There is another advantage in that the cold water can be magnetized by the magnetic force from the first and second magnetic members, thereby enabling to obtain magnetization water useful for the human body.

Figure 5 is a sectional view for illustrating a water dispenser of a refrigerator according to a second embodiment of the present invention.

As illustrated in Figure 5, the refrigerating chamber door 3 is formed at an inner side thereof with a panel 3b and at an external side thereof with a case 3a.

The refrigerating chamber door 3 is also disposed at an inner side thereof with a mounting member 20.

The mounting member 20 is fixedly fastened at a lower side thereof to a guide member 22 at a predetermined spacing from the case 3a.

The guide member 22 is invertedly disposed at one end thereof with a water discharge lever 26 for horizontal sliding, where the lever 26 is resiliently arranged by a spring 3d in a case guide groove 3c formed at one side of the case 3a.

The lever 26 is insertedly and horizontally fixed at an upper side thereof, that is, at an inner side of the guide member 22 to the first magnetic member 28.

The water discharge lever 26 is constructed such that, as

lδ

illustrated in Figure 6, both ends thereof can be insertedly disposed to enable same to slide into a guide groove 22a formed at the guide member 22.

Meanwhile, the mounting unit 20 is disposed at an upper side thereof with the water storage vessel 34. The water storage vessel 34 is provided at an upper side thereof with the lid 30 formed with the air hole 30a thereof for air ventilation therethrough, and at a lower side thereof with a lower cap 32 having a water discharge outlet 32a for discharging the cold water (W) stored in the water storage vessel 34.

Furthermore, the lower cap 32 is coupled therein to valve means 36 for selectively discharging the cold water (W) stored in the water storage vessel 34 according to operation of the water discharge lever 26.

The valve means 36 includes a cold water pipe 38 screwed to an inner side of the lower cap 32 and the operational axis 40 resiliently disposed by resilient member 24a at an inner side of the cold water pipe 38.

The operational axis 40 is fixedly disposed at an upper end thereof with a valve plate 44 for opening and closing the cold water pipe 38 to thereby control supply of the cold water (W), and is lengthwise and fixedly disposed at a lower end thereof with the second magnetic member 42 having a magnetic pole of polarity opposite to that of the first magnetic member 38.

Unexplained reference numerals 46a, 46b and 46c in Figure 5 are

packing members for preventing leakage of the cold water (W).

Next, operational effect of the water dispenser of a refrigerator according to the second embodiment of the present invention thus constructed will be described.

When the water storage vessel 34 stored with a predetermined quantity of cold water (W) is mounted to the mounting member 20 formed at one side of the refrigerating chamber door 3, the valve means 36 is closed to thereby prevent the cold water (W) in the water storage vessel 34 from being discharged.

In other words, the operational axis 40 of the valve means 36 is activated downward by water pressure of the water storage vessel 34 and the elastic force of the elastic member 24a to thereby cause the valve plate 44 to close an upper end of the cold water pipe 38, so that the water discharge outlet 32a can maintain a close state.

At this time, when the vessel (C) is pushed to thereby apply force to the water discharge lever 26 under a state where the vessel (C) such as cup and the like is placed underneath the water discharge outlet 32a, the water discharge lever 26 slides and opens the valve means 36 to thereby discharge the cold water (W), as illustrated in Figure 7.

In other words, when the water discharge lever 26 starts to compress the elastic member 24 for advance movement, as illustrated in Figure 7, the first magnetic member 28 moves to approach the lower cap 32 and simultaneously, the second magnetic member 42 is repulsed by the magnetic force generated by the first magnetic

member 28 to thereby raise the operational axis 40.

At this time, the polarities of the first and second magnetic members 28 and 42 are the same and are designed to face each other.

When the operational axis 40 compresses the resilient member 24a to thereafter be raised, the valve plate 44 formed at an upper end thereof is detached from the cold water pipe 38 to thereby allow the cold water (W) to be infused into the cold water pipe 38.

The cold water (W) infused into the cold water pipe 38 is discharged into the vessel (C) through the lower cap 32 and the water discharge outlet 32a, thus enabling the water discharge.

The cold water (W) discharged into the water discharge outlet 32a is magnetized by the magnetic force generated from the first and the second magnetic members 28 and 42, and at the same time, ring structure of the water is changed to hexagonal ring structure, that is changed to magnetization water, which is good for the health.

Meanwhile, when the force applied to the water discharge lever 26 is released, the water discharge lever 26 is returned to an original position by the elastic force of the elastic member 24, as illustrated in Figure 5, and at the same time, the first magnetic member 28 is detached from the lower cap 32 to thereby lose the magnetic force working on the second magnetic member 42.

The operational axis 40 is therefore activated downward by the elastic force of the elastic member 24a and at the same time, the valve plate 44 is lowered to thereby close an upper end of the cold

water pipe 38, so that the cold water (W) is stopped of its discharge.

Meanwhile, when the water dispenser is to be cleaned, the water storage vessel 34 is detached from the mounting member 20.

After the water storage vessel 34 is detached from the mounting member 20, and then the lower cap 32, cold water pipe 38 and the operational axis 40 are sequentially separated and cleaned. After the cleaning thereof is finished parts are assembled in the reverse order as against the detachment thereof, which is very simple.

As mentioned in the above, there is an advantage in the water dispenser of a refrigerator according to the second embodiment of the present invention thus constructed, in that structure thereof is simple for easy dismantlement and assembly, and at the same time, it is easy to clean same for maintaining an everclean state thereof, and more particularly, magnetized hexagonal water useful for human body can be obtained because the discharged cold water is magnetized by the magnetic force generated from the first and the second magnetic members.

Now, the water dispenser of a refrigerator according to the third embodiment of the present invention will be described.

First of all, it should be noted that, in case of the second embodiment, there has been a matter of concern where an accurate rectilinear motion of the operational axis 40 might go wrong when the water dispenser is used for a long time because only the first and the second magnetic members 28 and 42 are used.

In other words, an accurate control can be difficult because the elastic member 24a, the operational axis 40, the packing members 46c and the like are controlled by the first and the second magnetic members 28 and 42 according to a two-point control method.

Meanwhile, a detailed description of the water dispenser according to the third embodiment of the present invention will be omitted because schematic construction thereof is the same as that of the second embodiment, so that only the difference therebetween will be described.

The water dispenser of a refrigerator according to the third embodiment of the present invention is attached at one side of the water discharge lever 26 with a third magnetic member 28a, as illustrated in Figure 8.

The third magnetic member 28a is disposed with its polarity opposite to that of the first and the second magnetic members 28 and 42, and is so designed as to possess a less strong magnetic force than that of the first magnetic member 28.

In other words, the magnetic force at the third magnetic member 28a is good enough in strength thereof as to remove an error (by way of example, an amount to compensate a clearance between the cold water pipe 38 and the valve plate 44 caused by a slight inclination of the operational axis 40) generated in small during the rectilinear motion of the second magnetic member 42.

In other words, the strength of the magnetic force at the third

magnetic member 28a should be within a scope of not causing an impediment to a reciprocating movement of the second magnetic member 42.

Now, operational effect of the water dispenser of a refrigerator according to the third embodiment of the present invention will be described.

As shown in Figure 9, once a pressure is applied to the water discharging lever 26, the first magnetic member 28 moves toward the second magnetic member 42.

The second magnetic member 42 is raised by the repulsive force generated from between the first magnetic member 28 and the second magnetic member 42.

At this time, the magnetic force of the third magnetic member 28a is applied to the second magnetic member 42 to enable same to perform an accurate rectilinear motion.

Accordingly, the water dispenser of a refrigerator according to the third embodiment of the present invention does not generate any errors even though the second magnetic member 42 repeats continuous up and down operations.

Now, the water dispenser of a refrigerator according to a fourth embodiment of the present invention will be described.

As illustrated in Figure 10, the water dispenser of a refrigerator according to the fourth embodiment of the present invention is

protrudingly disposed at an external side of the operational axis 40 with a plurality of outwardly directed ribs 36a in order to maintain stability and accurate guide of the operational axes described in the aforementioned embodiments.

The water storage vessel 34 is screwed thereunder to a lower cap 26c employing a cold water passage 26a for enabling circulation of the cold water (W). The lower cap 26c is screwed thereunder to a water discharge cap 32c having a water discharge outlet 32a at a tip end thereof, as illustrated in Figures 11 and 12.

Furthermore, the water discharge outlet 32a is protrudingly formed therein, as shown in Figure 13, with a plurality of guide protrusion 32b in order to guide flow of the cold water (W), so that the cold water (W) does not disperse in all directions.

Meanwhile, the lower cap 26c and the water discharge cap 32c are resiliently mounted therein with valve means 36 for being vertically operated to selectively discharge the cold water (W) in the water storage vessel 34.

The valve means 36 includes the operational axis 40 for being resiliently disposed in the lower cap 26c by resilient member 24a, a valve plate 44 for being fixedly arranged at an upper end of the operational axis 40 to thereby open and close the cold water passage 26a and a first magnetic member 28 for being mounted under the operational axis 40. The operational axis 40 is protrudingly formed at an external side thereof with a plurality of ribs 36a.

A guide member 22 fixedly provided under the refrigerating

chamber door 3 is resiliently disposed therein by a spring 3d with the water discharge lever 26 for being horizontally and slidingly operated.

Furthermore, the water discharge lever 26 is mounted at an upper side thereof with a second magnetic member 42 for approaching the first magnetic member 28 according to the sliding operation to vertically lift the operational axis 40.

A detailed description of structure and operational effect for the first and the second magnetic members 28 and 42 are omitted herein because it is similar to the aforementioned embodiments.

Meanwhile, unexplained reference numerals 48a and 48b are packing members for preventing leakage of the cold water (W).

Next, operational effect of the water dispenser of a refrigerator according to the fourth embodiment of the present invention will be described.

First of all, the water storage vessel 34 stored a predetermined quantity of cold water (W) therein is mounted to a mounting part 20a, so that the cold water (W) in the water storage vessel 34 is not discharged.

Meanwhile, in case of discharging the cold water (W), a vessel

(C) such as cup and the like is made to be placed under the water discharge outlet 32a and a force is applied to a water discharge lever 26 to allow same to be slidingly operated. The water discharge lever 26 is then forced to compress the spring 3d to slidingly and

horizontally be operated, and at the same time, the second magnetic member 42 is moved to approach one side surface of the water discharge cap 32c.

At this time, a repulsive force is generated on the second magnetic member 42 and the first magnetic 28 because of the same polarity being approached thereto, so that the valve means 36 resiliently disposed within the lower cap 26c is force to be opened.

In other words, the operational axis 40 compresses the resilient member 24a and is lifted upward by the repulsive force generated in accordance with the approach of the second magnetic member 42, and the valve plate 44 is raised along with the operational axis 40 to thereby detach the operational axis 40 from the upper end of the lower cap 62, so that the cold water (W) in the water storage vessel 34 is infused into the cold water passage 56a.

The cold water (W) infused into the cold water passage 26a is discharged into the vessel (C) through the water discharge outlet 32a formed at a lower end of the water discharge cap 32c, which enables discharge of the cold water (w).

At this time, the cold water (w) discharged into the vessel (c) passes through the water discharge cap 32c to thereafter be magnetized by the magnetic force generated from the first and the second magnetic members 28 and 42, and at the same time, a ring structure of the cold water changes into a hexagonal ring structure. In other words, the cold water (w) becomes hexagonal water which is good for the health. The cold water (w) is also discharged on the straight by the plurality of guide protrusion 32b

protrudingly formed on an inner periphery of the water discharge outlet 32a to thereby prevent same from being dispersed.

Meanwhile, when the force applied to the water discharge lever 26 is released, the lever 26 returns to an original state by way of the elastic force of the spring 3d and at the same time, the second magnetic member 42 is detached from the water discharge cap 32c to thereby lose the magnetic force generated from between the first magnetic member 28 and the second magnetic member 42. Accordingly, the operational axis 40 is activated downward by the elastic force of the elastic member 24a, and , at the same time, the valve plate 44 is lowered to close the upper end of the cold water passage 26a and to thereby stop discharge of the cold water (w).

As mentioned above, there is an advantage in the fourth embodiment of the water dispenser of a refrigerator according to the present invention in that structure thereof is simple and assembly and dismantlement thereof is easy and cleaning thereto is bandy for maintaining the water dispenser at all times, and more particularly, the discharged cold water (w) is magnetized by the magnetic force of the first and the second magnetic members to thereby enable to obtain magnetized hexagonal water useful for the health of a human body.

Now, the water dispenser of a refrigerator according to a fifth embodiment of the present invention will be described.

A water dispenser of a refrigerator according to the fifth embodiment of the present invention uses magnetization means

instead of the first magnetic member in the fourth embodiment.

As illustrated in Figure 15, the water dispenser of a refrigeration according to the fifth embodiment of the present invention is formed at an inner side of the refrigerating chambered 3 with a mountain part 20a for mounting the water storage vessel 34 thereto.

The mounting part 20a is releasably screwed to a lower cap 26c connected to the water storage vessel 34.

The water storage vessel 34 is the same in its structure as the above mentioned in the above embodiments, so that no further description thereof will be omitted.

Meanwhile, the refrigerator chamber door 3 is disposed at one side thereof with magnetization means 55 having the same polarity as that of the second magnetic member 42 connected to the operational axis 40.

The refrigerating chamber door 3 is formed at an external side thereof with a case guide groove 3c and at an inner side of the case guide groove 3c there is disposed manipulating means 57.

The manipulating means 57 is a push switch so constructed as to be connected to and detached from electrical contacts 70 and 75, and to be restored by an elastic member 80 according to movement of the swing member 73.

Now, operational effect of the water dispenser of a refrigerator

according to the fifth embodiment of the present invention thus constructed will be described.

Referring to Figure 16, when a user wants to discharge the cold

5 water (W) from the water storage vessel 34, a vessel (C) is positioned underneath a water discharge outlet 32a. Then the vessel (C) is pushed forward to thereby cause the swing member 73 to contact the electrical contacts 70 and 75.

10 At this time, the magnetization means 55 is applied by electric power to thereby perform a role of an electromagnet and to supply a repulsive force to the second magnetic member 42.

The operational axis 40 connected to the second magnetic member

15 42 serves to push upward the valve plate 44 disposed within the water storage vessel 34 according to the repulsive force.

In other words, a direct current flows in the magnetization means 55, whereby an tip end of the second magnetic member 42 and

20 another tip end of the magnetization means 55 situated nearby repulse each other due to the same polarity thereon.

When the valve plate 44 is raised, the cold water (w) stored in the water storage vessel 34 is infused into a cold water pipe 38 to „-. thereafter be discharged sequentially through the lower cap 26c and the water discharge outlet 32a for water dispensing .

Furthermore, the water discharge outlet 32a is formed at an inner side thereof with a guide protrusion 32b, so that the cold

_ water (w) is not dispersed, only to be easily contained in the

vessel (c)

Meanwhile, when the vessel (c) which has been pressing the swing member 73 is removed, the swing member 73 returns to an original state thereof by way of restoration force of the elastic member 80, as illustrated in Figure 15, hereby causing the electrical contacts 70 and 75 to be separated therefrom.

At this time, the magnetization means 55 is stopped of power supply to thereby lose a magnetizing force, so that the operational axis 40 is lifted downward.

In other words, the valve plate 44 serves to close the cold water pipe 38 to thereby cause the cold water (w) in the water storage vessel 34 not to be discharged any more.

Accordingly, there is an advantage in the water dispenser of a refrigerator according to the fifth embodiment of the present invention, in that a valve plate can be controlled in opening and closing thereof by way of magnetization means and magnetic member, thereby increasing reliability, thereof for prevention of erroneous operation and reducing manufacturing cost thereof because of less number of parts involved for manufacturing thereof compared with the conventional water dispenser. 5

As apparent from the foregoing , although the present invention has described about five embodiments, those skilled in the art will appreciate that various modifications, additions and substitution are possible, with departing from the scope and the spirit of the Q invention, as disclosed in the accompanying claims, and it should

be also noted that anything that serves to open and close the valve plate by activation of the operational axis according to electromagnet and magnetization means belong to the scope of the present invention as disclosed in the claims.
