Problems solved by technology

And, due to these factors, if the discharge characteristics of the discharge part change, sparks may be generated from the discharge part toward the opposite part.
As a result, streamer discharge cannot be performed, and the generation amount of low-temperature plasma is reduced, resulting in a problem of reduced air purification efficiency.
In addition, this spark is noise to the user, or electromagnetic waves are generated along with the spark to cause malfunction of electronic devices near the discharge device, which has become a problem.

Embodiment approach 1

[0091] First, with reference to Embodiment 1 image 3 and Figure 4 be explained.

[0092] image 3 , is an exploded perspective view of the air purification device (10) according to the first embodiment. This air purifying device (10) is a domestic air purifying device used in general households or small-scale shops. Also, this air purifying device (10) is an air purifying device that generates low-temperature plasma by streamer discharge to purify the air to be treated.

[0093] The air purification device (10) comprises a casing (20) formed by a box-shaped casing body (21) with one end open and a front panel (22) mounted on the open end. Two sides of one side of the front panel (22) of the casing (20) form suction ports (23). Also, in the casing body (21), the top plate is close to the back plate to form an outlet (24).

[0094] Inside the casing (20), an air passage (25) through which the indoor air to be treated flows is formed between the air suction port (23) and ...

Embodiment approach 2

[0129] Next, refer to the air purifier (10) according to the second embodiment Figure 7 be explained. The air purification device (10) according to the second embodiment is different from the discharge device (40) according to the first embodiment in configuration. Specifically, in contrast to the discharge device (40) of the first embodiment, the resistor (60) is provided on the conduction circuit between the power supply (45) and the discharge part (61), the discharge device (40) of the second embodiment , the resistor (60) is arranged between the power supply (45) and the opposite part (62).

[0130]In the discharge device (40) of the second embodiment, the discharge electrode (41) includes the discharge portion (61) serving as the base point of streamer discharge, and a discharge-side support member (43) supporting the discharge portion (61). The discharge-side support member (43) includes a plate-shaped support member (43a) extending up and down, and a fixing member (4...

Embodiment approach 3

[0145] Next, refer to the air purifying device (10) according to the third embodiment Figure 9 be explained. In the air purification device (10) according to the third embodiment, the configuration of the discharge device is different from that of the discharge device (40) in the first embodiment.

[0146] like Figure 9 As shown, in the discharge device (40) of the third embodiment, the resistor (60) is composed of an electrodiffusive material synthesized by adding carbon fiber to ABS resin (acrylonitrile-butadiene-styrene resin). Still, the volume resistivity of this electrodiffusive material, at 10 5 to 10 12 in the range of Ωcm.

[0147] In this example, the resistor (60) formed of the electrodiffusive material constitutes the support member (43a) of the discharge-side support member (43). Also, on this support member (43a), as in the first embodiment described above, a fixing member (43b) and a discharge needle (discharge portion) (61) are supported. On the other h...

Abstract

In a discharge device for performing streamer discharge between a discharge electrode (41) including a plurality of discharge parts (61) and a counter electrode (42) including a plurality of counter parts (62) confronting the discharge parts (61), a resistor (60) is provided in a current carrying path between power source means (45) and the discharge parts (61).

Description

technical field [0001] The present invention relates to a discharge device for streamer discharge between a discharge electrode and a counter electrode, and an air purification device including the discharge device, and in particular to the spark suppression technology of the discharge device. Background technique [0002] Heretofore, air purification devices including discharge devices utilize plasma generated by discharge as a method for decomposing and removing odorous components or harmful components in the air. Among the air purifiers, the streamer discharge type air purifier achieves a high air purifying effect by using lower electric power, and is a better technique for decomposing or deodorizing harmful components. [0003] For example, as shown in Patent Document 1 (Japanese Patent Laid-Open No. 2002-336689 ), a streamer discharge air purifying device includes, as a discharge device, a discharge electrode having a plurality of needle-shaped discharge parts, a discha...
