[0069] First, a first embodiment will be described with reference to FIGS. 1 to 3 .

[0070] Fig. 1 is an exploded perspective view of an air cleaning device (10) according to this embodiment. The air cleaning device (10) is a household air cleaning device used in general households, small-scale stores, and the like.

[0071] The air cleaning device (10) has a casing (20) composed of a box-shaped casing body (21) with one end open and a front panel (22) mounted on the open end surface of the casing body (21). Air suction ports (23) are formed on both side surfaces of the front panel (22) side of the casing (20). An air discharge port (24) is formed on the top plate of the housing main body (21) near the back plate.

[0072] In the casing (20), an air passage (25) is formed through which air to be processed, that is, room air, flows from the air suction port (23) to the air discharge port (24). In the air passage (25), various functional components (30) for air purification ...

[0123] Next, a third embodiment of the present invention will be described in detail with reference to the drawings.

[0124] Fig. 11 is an exploded perspective view of the air cleaning device (10) according to the third embodiment; Fig. 12 is a view showing the inside of the air cleaning device (10) viewed from above. This air cleaning device (10) is a household air cleaning device used in general households, small-scale stores, etc., and is the same as the air cleaning device of the first embodiment.

[0125] An air cleaning device (10) has a casing (20) composed of a box-shaped casing body (21) with one end open and a front panel (22) mounted on the open end surface of the casing body (21). An air suction port (23) for introducing the gas to be processed, that is, indoor air, is formed on the two side surfaces and the upper surface of the casing body (21) and the front central part of the front panel (22). An air discharge port (24) through which indoor air flows out is fo...

Abstract

Disclosed is a discharge device (40) for generating a streamer discharge from the tip of a discharge electrode (41) towards a counter electrode (42). The discharge electrode (41) in the shape of a wire or rod is disposed substantially parallel to the counter electrode (42), whereby, even when the tip of the discharge electrode (41) becomes worn out, the shape of the tip of the discharge electrode (41) remains unchanged and the distance between the discharge electrode (41) and the counter electrode (42) remains unchanged. As a result, even when the tip of the discharge electrode (41) becomes worn out, the streamer discharge stability will not fall.

Description

technical field [0001] The present invention relates to a discharge device for performing streamer discharge from a tip of a discharge electrode to a counter electrode, and an air cleaning device using the discharge device. Background technique [0002] Hitherto, a discharge device comprising a pointed needle-shaped discharge electrode and a planar counter electrode is known as a discharge device for performing streamer discharge (for example, Japanese Laid-Open Patent Publication No. 2002-361028). In this discharge device, the discharge electrodes are arranged in a direction at right angles to the surface of the counter electrode, and the front end is close to the counter electrode. In this discharge device, a discharge voltage is applied to two electrodes, and a streamer discharge is generated from the tip of the discharge electrode to the counter electrode. [0003] In the discharge device, cool plasma is generated by streamer discharge. Highly reactive substances (acti...
