Because they are located far apart from each other, it takes up a lot of installation space, and when changing the installation location, the positive electrode 2, negative electrode 3, and blower 4 must be installed and changed separately, which is very difficult. It was a hassle. The purpose of the present invention is to overcome these conventional drawbacks.

も構わない。Next, one embodiment of the present invention will be described in detail based on the drawings. In FIG. 1 (front view) and FIG. 2 (side view), the fan case 5 has a frame shape with a circular inner peripheral surface, and in the center thereof,
A circular motor accommodating portion 6 with an open front is integrally connected by a plurality of ribs 7. A motor for rotating a fan 8 is built in the motor storage part 6. The fan 8 rotates within the frame of the fan case 5 without protruding from the fan case 5, and sucks air from the intake port on the rear surface of the fan case 5 through the air outlet 9 on the front surface between the ribs 7.
It blows out. The fan case 5 is provided with a pair of stepped holes 10 as electrode mounting portions at opposing positions on its diameter line, and these stepped holes 10 are provided with positive and negative DC static elimination electrodes 11.
・12 is fitted. These static eliminating electrodes 11 and 12 have the same structure, with a collar 13 and a connecting hole 14 as shown in FIG.
An electrode needle 16 is implanted in an insulator 15 that has a . Then, the electrode needle 16 is crimped and connected to the core wire of the high-voltage cable 17 in the connection hole 14, and the connection part is sealed with resin. protrudes inward from the circular inner circumferential surface of the fan case 5, and faces plus and minus on the same diameter line. Therefore, when positive and negative DC high voltages are applied to the positive and negative static elimination electrodes 11 and 12 from a DC high voltage power supply (not shown), respectively, and a corona discharge is caused between the electrode needles 16, the ions produced thereby are transferred to the fan. Since it is blown away by the wind caused by 8, static electricity can be removed from distant charged objects and even in narrow spaces. The above example uses a DC static eliminator using a DC high voltage, but when performing AC static eliminator using an AC high voltage, the AC static eliminator shown in FIG. It is sufficient to attach the bridge 18 to the fan case 5. This static elimination electrode 18 is made by attaching a cylindrical earth electrode 19 that covers the periphery of the electrode needle 16 to an insulator 15 in which the electrode needle 16 is implanted in the same manner as described above. In both cases of FIG. 3V and FIG. 4, as the electrode needle 16, a stainless steel needle or a resistively conductive ceramic needle (conductive ceramic mixed with carbon, etc. and sintered to obtain a predetermined resistance value) is used. . When using a resistive conductive ceramic needle, there is no need for a separate current limiting element because the needle itself has a current limiting effect, but when using a stainless steel needle, a resistor or capacitor (AC ) to the high voltage power supply side. Although the above example shows an example in which the high voltage tS is installed separately from the fan case 5, it is also possible to install the high voltage power source in the motor storage part 6, which is not affected by the wind from the fan 8, so that a structure in which the high voltage power source is also integrated can be achieved. . Further, the static elimination electrode 8it1, 12 or 18 may be installed on the suction side of the fan 8, and the static elimination electrode is not limited to a needle-shaped one, but may be a wire-shaped one.
