Embodiment approach 1

[0025] figure 1 It is an exploded perspective view of the structure of the electrostatic precipitator. figure 2 It is an exploded perspective view of the structure of the dust collecting member of the electric dust collector of this embodiment. Such as figure 1 As shown, the electrostatic precipitator 1 is composed of a dust collecting unit 2 and a main body 3, and the dust collecting unit 2 is accommodated in the main body 3, and installed on an indoor unit of an air conditioner or the like. The indoor air 4 passes through the dust collecting member 2 to collect dust particles contained in the indoor air 4 , and then passes through the heat exchanger of the indoor unit for heat exchange and is blown into the room. Such as figure 2 As shown, the dust collecting member 2 is composed of a casing 5 made of a molded resin material or the like, a discharge electrode 6 , a counter electrode 7 and a dust collecting filter 8 . The casing 5 is formed in a substantially rectangu...

Embodiment approach 2

[0042] Use below Figure 5 Embodiment 2 will be described. Components that are the same as those in Embodiment 1 are given the same symbols, and their descriptions are omitted. Figure 5 It is a perspective view showing the structure of the dust collecting member 2 of the electric dust collector according to Embodiment 2 of the present invention.

[0043] In order to take a large suction area of ​​indoor air in equipment such as air conditioners and improve the maintenance of dust collection parts such as cleaning, dust collection parts 2 are divided as shown in the figure and arranged in multiples.

[0044] In the second embodiment of the present invention, the sound wave can be irradiated by the sound wave generating means 14 to such a plurality of dust collecting members 2 . Such as Figure 5 As shown, the sound wave generating mechanism 14 is disposed between the two dust collecting members 2 so that the corona discharge of the both dust collecting members can be irradi...

Embodiment approach 3

[0047] Use below Figure 6 Embodiment 3 will be described. Components that are the same as those in Embodiments 1 and 2 are denoted by the same symbols, and descriptions thereof are omitted. Figure 6 An exploded perspective view showing the configuration of the dust collecting member 2 according to Embodiment 3 of the present invention.

[0048] The third embodiment differs from the first embodiment in that in the first embodiment, the corona discharge is irradiated with sound waves and diffused, but in the present embodiment, the vibration generating mechanism 20 is arranged so as to vibrate the discharge electrode 6 or the counter electrode 7, Vibration conditions are controlled by the vibration control device 21 . With such a configuration, the corona discharge can be diffused due to the vibration of the discharge electrode 6, and the discharge range can be expanded, that is, the dust collection efficiency can be improved. exist Figure 6 In this case, the support body...

Abstract

An electric dust collector of a high dust-collection rate is disclosed. The dust collector includes a charging section, a dust collecting section and acoustic wave generating means which irradiates acoustic waves to at least a part of a discharge portion of the charging section. The acoustic wave generating means irradiates the acoustic waves to a corona discharging area, so that an area where corona discharge is generated is enlarged, and at the same time, a probability of collision between particles is increased for accelerating cohesion of the particles. As a result, the dust collection rate is improved.

Description

[0001] This divisional application is a divisional application of the following application: [0002] Application number: 02126358.2; [0003] Application date: July 19, 2002; [0004] Applicant: Matsushita Electric Industrial Co., Ltd.; [0005] Title of Invention: Electric dust collection device, dust collection method, and air supply device using the same technical field [0006] The present invention relates to an electric dust collector for collecting dust in the air, and more specifically relates to an electric dust collector and a dust collector which can be used in an air conditioner or an air cleaner, have high dust collection efficiency, and use corona discharge. method. Background technique [0007] The electric dust collector is mainly composed of a charging part that generates corona discharge and charges the passing dust particles, and a dust collection part that captures the charged dust particles. It is composed of components and is installed in the air in...
