VOLTAGE

Technical Field

[1] This invention relates to an ionizer removing static electricity of charged bodies by corona discharge. More specifically this invention relates to a bartype ionizer in which by an adjustment button easily can be controlled the level of output voltage applied to discharge needles. Background Art

[2] A corona discharge-type ionizer is an apparatus removing static electricity of charged body by using positive ions and negative ions generated by corona discharge through applying voltage to discharge needles. In such a corona discharge-type ionizer as high voltage of several kV applied to discharge needles generates strong electric field at the end of discharge needles, particles floating in the air adhere to discharge needles and the effect of removing the static electricity falls as time passes. Generally as the output voltage applied to discharge needles increases, generated ions increase so that removing speed of static electricity becomes quicker and effective removing distance of static electricity increases. However there is a problem that the more output voltage increase, the stronger electric field is generated so that the quantity of dusts adhered to discharge needles increases more. Therefore according to the environment under which an ionizer is installed, it is necessary that the level of output voltage applied to the discharge needles is adjusted. For example, when an ionizer is installed in a circumstance under which dusts are generated much, it is necessary to set up output voltage relatively low compared to a circumstance under which dusts are not generated much.

[3] But an ionizer according to prior art is sent out with a state that the level of the output voltage is fixed in advance by manufacturer to fit to an environment under which the ionizer is installed first so that there is a problem that the level of the output voltage cannot be adjusted after installation.

[4] There is a Korean patent application no. 10-2005-0032534 "A bartype ionizer" filed on 19 April 2005 by the applicant of this invention as a prior art of this field of technology. This invention relates to a bartype ionizer removing static electricity of charged body by generating ions through corona discharge and makes it possible adjust network address, duty ratio of high voltage of pulsed AC, frequency in the bar itself and makes the ions for removing static electricity generated smoothly by improving an air injection socket.

[5] However, although the prior art of the applicant can adjust network address, frequency and duty ratio of an ionizer in a bar itself too, the problems about the output voltage adjustment as mentioned above has not been solved as usual. Disclosure of Invention

Technical Problem

[6] This invention was invented to solve the problems of prior art described above. The subject of this invention is to provide a bartype ionizer capable of controlling output voltage which makes the level of output voltage applied to discharge needles adjusted easily by using an adjusting means so that a user can adjust the level of output voltage according to his/her own decision free from the initial values set up by manufacturer.

[7] Other purposes and merits of this invention will become more apparent by reading the following detailed description of this invention and referring to the accompanied drawings. Technical Solution

[8] At the below with reference of the accompanied drawings a detailed technical means for solving problems is explained.

[9] To solve the subject of this invention an ionizer doesn't need to have a specific form but to help understanding of this invention we explain with reference to figures 1 and 5 about the external shape and the operational status of an ionizer which can be used in this invention.

[10] At the both ends of a bar (200) a slot hole (210) is formed so that a bar (200) can be fixed to wall etc by a bolt. At the center of a bar (200) a middle bracket (300) is installed so that although the bar (200) is long, its central part doesn't dip and a slot hole (310) is formed at the middle bracket (300) too for fixing it to wall etc. At the lower part of a bar (200) are installed plurality of tips (100) from which ions come out.

[11] At each tip (100) a discharge needle to which high voltage generated from a high voltage module (640) is applied is installed and static electricity of charged body is removed with positive ions and negative ions generated from discharge needles by corona discharge.

[12] As shown in figure 5 according to necessity a bar (200) may be rotated so that the direction of the tip (100) can be adjusted to suit the position of charged body. And as the bar (200) is connected to the middle bracket (300) via a hinge (400) and a ring(450), the bar can rotate at angles of 45 degree and 90 degree with the help of the hinge (400) and the ring(450).

[13] As shown in figures 6 to 11, in a bartype ionizer according to this invention a display unit(510) is installed in a bar to display the status of set-up and operation of an ionizer so that a user can check easily the status of an ionizer.

[14] And although we didn't illustrate, a display unit (510) may be installed in a bar itself as well as in an RMS (remote monitoring system) which is a system monitoring plurality of ionizers from remote places by using a remote controller in order to control ionizers remotely. An RMS itself corresponds to a prior art so that we don't explain about it separately.

[15]

[16] On one hand, the display unit(510) displays items of ionizer selected by a user as referred below and numeric values set up per each item by a user, and includes an RX/ TX light emitting part flickering in case of communication with PC or controller, an ION light emitting part lighted up in case remaining ion current quantity is lower than standard value, a H/V light emitting part lighted up in case voltage applied to discharged needles is lower than standard value, a POS light emitting part lighted up in case normally positive ions are generated, and an NEG light emitting part lighted up in case normally negative ions are generated. If dusts adheres to discharge needles, the quantity of ion current may become lower than the reference value, and the voltage applied to discharge needles may become lower than the reference value in case there is a fault in the high voltage module generating high voltage. Each light emitting part may be embodied by using LED (light emitted diode).

[17] At the left side of the display unit (510) there is installed an operation switch(520). If a user turns on this switch upward, the ionizer operates continuously too in case a fault occurs in a high voltage module (640). When an RMS collectively monitoring operation status of several ionizers is built, it is preferable to use the operation switch (520) after turning it on upward in order to check whether any ionizer has a fault. If a user turns off the switch downward, an ionizer stops its operation when a fault occurs in the high voltage module (640). If a fault occurs at a high voltage module (640), static electricity is not removed. So in case an ability to remove static electricity is lost and it is necessary to stop the operation of an ionizer, it is preferable to use the operation switch after turning it off downward.

[18] At the right side of the display unit (510) there is installed a control unit (530) so that it is possible to set up all sorts of numerical values necessary for operation of an ionizer. The control unit (530) consists of a remote controller selection button (531) selecting whether to control remotely by external remote controller or not, a selection button (532) selecting set-up items, a up button (533) setting up the numerical values of selected items, and a down button (534).

[19] Figure 7 illustrates a case of setting up network address, figure 8 a case of setting up frequency, figure 9 a case of setting up duty ratio, figure 10 a case of setting up positive output voltage, figure 11 a case of setting up negative output voltage.

[20] By pressing a selection button (532) several times a user makes an item appear on a

display unit (510) which he/she wishes to set up. "A" denotes address, "F" frequency, "d" duty ratio, "p" positive output voltage level, and "n" negative output voltage level. Next a user inputs desirable set-up values of corresponding items by pressing a up button (533) and a down button (534). With the pressing of a up button (533) and a down button (534) there appear varying numerical values on the display unit (510).

[21] As numerical values of each set-up item appear on the display unit (510), a user can check the set-up values of each item easily. The displayed part of items and set-up values on the display unit can be implemented by using FND (Flexible Numeric Display).

[22] For example, the positive output voltage and negative output voltage are set up in advance to 10 levels at interval of 0.5kV from 8kV to 12.5kV as shown in the following table 1, and the positive and negative output voltages may be set up differently each other so that according to the installment environment it is possible to adjust the ratio of generated positive ions and negative ions.

[23] Table 1 [Table 1] [Table ]

[24] Figure 12 is a block diagram of an output voltage set-up circuit (600). A regulator(620) adjusts the input voltage of a DC power source (610) appropriately and provides it to a high voltage module (640). For example, a regulator (620) lowers input voltage of 24V and provides it to a high voltage module (640), and a variable resistor (630) is inserted between the regulator (620) and the high voltage module (640), the value of the resistor varies according to the output voltage level set up by a user

through a control unit (530). According to the varied resistor values the output voltage of the regulator (520) is adjusted to 13-20 V and is provided to the high voltage module (640), and the high voltage module (640) generates pulsed AC high voltage of 8~12.5kV from it and applies it to discharge needles. At this time, if a user sets up a desirable level by using a level controller (650), the level controller commands to a variable resistor (630) to adjust the resistor value according to it in order to generate the in advance set up positive and negative output voltage according to each level as shown in table 1. If positive and negative output voltage are generated through such procedures, positive ions and negative ions corresponding to it are generated so that it is possible to adjust the quantity of two ions.

[25] Like this way, the present invention may be transformed variously and take several types of form and in the above detailed description of the invention only a specific embodiment according to it is described. However this invention should be understood not to be restricted to a specific form mentioned above and on the contrary it should be understood to include all the modifications, equivalents and substitutes existing in the spirit and scope of this invention

Advantageous Effects

[26] As through embodiment of this invention the level of output voltage applied to discharge needle can be controlled easily only by a control means installed in the bar itself, a user can get effective remove of static electricity by setting up the optimal level of the output voltage according to the environment under which an ionizer is installed. In addition, in the present invention a user can check the output voltage of an ionizer easily for the level of the set up output voltage is displayed on the bar itself.
