Since the discharge occurs strongly near this exposed electrode,
The electrodes are easily corroded by plasma etching, oxidation, etc. caused by discharge. When such corrosion occurs, the discharge becomes uneven, resulting in uneven charge removal and charging effects, which poses a problem in practical durability.

案出した。Therefore, with the aim of improving the above-mentioned durability, the applicant has
It has a dielectric material, at least two electrodes buried in the dielectric material, and an exposed electrode, and the buried electrode has a predetermined discharge starting voltage when an alternating current voltage is applied between them, and the dielectric The bare electrode is placed at a position near a part of the surface of the body where a discharge occurs, while the exposed electrode is located at or near a part of the surface and has a discharge starting voltage between it and any buried electrode. In Japanese Patent Application No. 61-18954, a discharge device was devised in which the discharge device was installed at a position higher than the predetermined discharge starting voltage.

常に難しい。Although the above-mentioned proposal significantly improves the durability against electrode corrosion due to discharge, there is a problem that the surface absorbs moisture. In other words, if the discharge device is not in use, moisture in the air will adhere to the surfaces of the dielectric and electrodes, so even if the power is turned on, discharge will not occur unless the humidity on the surfaces of the electrodes and dielectric decreases. have. For this reason, when the atmospheric humidity is high,
When a device forms condensation in cold weather, it is very difficult to discharge the device.

Since we decided to generate heat by applying a voltage, the heat is quickly and efficiently transferred to the dielectric, making it possible to instantly raise the surface temperature of the discharge device, quickly evaporating moisture adhering to the surface, and discharging. The effect is that the action can be started easily.
