A base 30 for mounting the leg portions 101 and 102 is disposed on the surface of the cover.

Since the antistatic modules 1A, 1B, and 1C are identical except for the types of substrates to be described later, each of the antistatic modules 1A, 1B, and 1C will be generally referred to as "antistatic module 1" or "mode" hereinafter. Group 1". In addition, the configuration of the parts in module 1 will be shown by a common symbol. In addition, for the detailed description of the drawings, the symbols will only be given to the corresponding positions of any of the modules 1.

Therefore, in the module 1C, signals are transmitted from the screw electrodes 108 to the discharge pins 10 and 10 of the corresponding substrate 12 and through the pattern of the front electrode substrate 12 to the right bottom screw electrode 108. The high voltage signal transmitted to the right bottom screw electrode 108 is transmitted to the left bottom screw electrode 108 adjacent to the antistatic module 1B. As in the module 1B, the high voltage signal is transmitted from the left bottom screw electrode 108 to the discharge needle 10 of the corresponding substrate 12 and via the front electrode substrate 12 to the right bottom screw electrode 108. In addition, the high voltage signal is transmitted from the right bottom screw electrode 108 of the module 1B to the left bottom screw electrode 108 of the module 1A, so that the high voltage signal is transmitted to the electrode substrate 12 in the module 1A. Discharge needles 10 and 10.

As described above, the positive polarity high voltage is sequentially supplied to the discharge needles 10 of the respective electrode substrates 11 of the antistatic modules 1A, 1B, and 1C, and the negative polarity high voltage is sequentially supplied to the respective electrode substrates 12 of 1C, 1B, and 1A. Discharge needle 10. Therefore, the cations are generated by the discharge needles 10 and 10 of the upper electrode substrate 11 of the respective module 1, and the anions are generated by the discharge needles 10 and 10 of the lower electrode substrate 12.

The control circuit disposed on the main substrate S0 respectively supplies power or control signals and directly outputs a high voltage signal to the negative polarity high voltage circuit board in the cover 32, and is in the cover 31 via the relay substrates S1 _B and S1 _A The high voltage board outputs a high voltage signal. In addition, the control circuit directly inputs and outputs signals for the arrangement of the modules of the axial fan 13 or the limit switch 17 and the configuration of the antistatic module 1C, and the other modules 1A and 1B are via the relay substrates S1 _A and S1 _B. Input and output signals.

For example, the control circuit determines whether the ion balance is appropriate by detecting the voltage of the reference voltage line shared by the respective substrates, and adjusts the driving pulses supplied to the left and right high voltage circuit boards based on the determination result. In order to adjust the air volume of the axial fan 13, the control circuit sometimes changes the control signal for the axial fan 13. When the detection signal from the limit switch 17 of the respective module 1 is input and the detection signal is turned off (meaning the louver 15 is separated), the control circuit stops the supply of power to the high voltage circuit or to the axial fan 13.

According to the static eliminator of the above embodiment, the discharge needle 10, the axial flow fan 13 and the substrate S are housed in a casing 14 so that the antistatic module 1 can be made in a small size. Since the high voltage circuit is embedded in both of the end caps 31 and 32, space is saved to make a small size device.

Embodiments of the invention are not limited to the above, and the following types are contemplated.

First, in the above embodiment, the relay substrate is disposed in the modules 1A and 1B in addition to the module 1C having the main substrate S0, and includes various signals for signals of the high voltage circuit board. Connected in series to the main substrate S0. However, in addition to the main substrate S0, any substrate may have a control function in addition to the relay function of the signal, so that the substrate in each module 1 can be transmitted for signal processing or control under the centralized control of the main substrate S0. Configuration in the same module. The relay substrate does not need to relay all signals but can only relay the power supply for the drive, the reference voltage, and the control signals to the high voltage circuit board. In this case, only the wiring for the power supply and the reference voltage line can be connected for connection between the modules 1 and between the relay substrates.

In addition to the above lines, a transmission line for signals of any one of the axial fan 13 and the limit switch 17 is formed on the relay substrate, and the corresponding configuration in the module 1 is connected to the corresponding transmission line, and is used for another A configured signal can be transmitted to the control substrate S0 on another path.

When the number of modules 1 is increased, a given number of modules 1 to be connected are formed in groups, the entire connector of the module 1 is divided into a plurality of groups, and power circuits can be arranged for each group.

It is also possible to individually connect each of the module 1 or the high voltage circuit board to the main substrate S0 without the relay substrate being disposed. For example, it is possible to prepare a plurality of substrates having different numbers of apertures in advance, and select substrates having apertures equal to or greater than the number of modules 1 from the substrates. In this case, the substrate may not need to be placed in one of the modules 1 and a substrate having a width extending to the plurality of modules 1 may be used.

The high voltage signals of the discharge pins 10 of each of the modules 1 are not limited to series connection, but it is also possible to supply a high voltage signal to each of the modules 1 by parallel connection.

In addition, the high voltage circuit board is not necessarily disposed in both of the covers 31 and 32. For example, in the method of alternately applying a positive polarity voltage and a negative polarity voltage to each of the discharge needles 10, the high voltage circuit board may be disposed in any of the covers. Although the device can be made larger, the resin plate molded with a high voltage circuit board can be disposed at positions other than the covers 31 and 32 (for example, the connector body and the upper bracket 21 of the module 1) between).

In each of the modules 1 in the above embodiment, the four discharge needles 10 are arranged on the two electrode substrates 11 and 12 by dividing the discharge needle into two groups, but the number of the discharge needles 10 and the electrodes The number of substrates is not limited to this. Further, when the positive polarity voltage and the negative polarity voltage are alternately applied to the discharge needle 10, the plurality of discharge needles 10 may also be disposed on the one electrode substrate having the opening and along the circumference of the opening.

The method of connecting the electrode substrates between the modules 1 is not limited by the method shown in the above embodiments. For example, the male connectors are respectively disposed on one side of each of the housings and the female connectors are disposed on the other side, and the connectors are electrically connected to the electrode substrate, and thus may be connected between the modules 1 by the male connectors The electrical connection and the mechanical connection are simultaneously achieved adjacent to the female connector of the housing.

As a member of the connecting body of the antistatic module 1 mounted on the brackets 21 and 22, the guide rail 20 is used in the above embodiment, but is not limited thereto, and the method of introducing the rivet foot or screwing the housing to the bracket may be employed. method.

The frame supporting the connector of the antistatic module 1 is not limited to a pair of top and bottom plate brackets 21 and 22, but a metal body having a constant cross section and an open end face can be used as a single body of the bracket. For example, the top, bottom and back of the connector can be supported by a U-shaped bracket. In addition, if the module 1 is completely fixed by the brackets, the bracket can be formed into a plate-like frame, and the module 1 can be fixed to the frame.

If the antistatic module 1 is firmly supported by the bracket, the module 1 is not necessarily connected. If the module 1 is made non-removably, this does not matter, even if there is a small gap between the modules 1.

The discharge needle 10 and the axial fan 13 need not be housed in one housing; the following configuration can be used: each of the discharge needle and the axial fan is housed in a separate housing and the housings are connected or paired quasi. Further, a plurality of axial fans 13 are arranged at a given interval and fixed to a plate-shaped frame, and are mountable with support before the axial fans (the axial fans have openings at the front and the back) And the housing of the discharge needle afterwards.

All embodiments have such a configuration: an assembly of discharge needles serving as ion generating electrodes, an axial flow fan, and an open-ended housing to form an anti-static module, the necessary number of anti-static modules being arranged in one direction, and Each module is integrated by a method of connecting between modules or securing the modules to a bracket. According to such a configuration, it is possible to manufacture a static eliminator having a width that satisfies the needs of the field, so that the convenience is greatly improved as compared with the conventional product.
