[0070] First, refer to figure 1 Turning to Fig. 3, the first embodiment is explained.

[0071] figure 1 , is an exploded perspective view of the 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.

[0072] 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.

[0073] 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 pu...

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

[0124] Figure 11 It is an exploded perspective view of the air cleaning device (10) according to the third embodiment; Fig. 12 is a diagram showing a state of seeing the inside of the air cleaning device (10) 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 indoo...

Abstract

In an electric discharge device (40) performing streamer discharge from the top of a discharge electrode (41) toward an opposing electrode (42), the discharge electrode (41) with a liner or bar-like shape is placed substantially parallel to the opposing electrode (42). The structure results that the shape of the top of the discharge electrode (41) does not change even if the top wears and the distance between the discharge electrode (41) and the opposing electrode (42) also does not change. This prevents stability of streamer discharge from lowering even if the top of the discharge electrode (41) wears.

Description

[0001] This application is a divisional application of an invention patent application with an application date of June 22, 2004, an application number of 200480023480.8, and an invention title of "discharge device and air purification device". technical field [0002] 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 [0003] 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 ...
