Problems solved by technology

[0005] However, since the existing dust collecting device is composed of parallel flat plates to form the dust collecting electrode and the high voltage electrode of the dust collecting part, there is a problem that it is difficult to reduce the size of the device and to improve the performance.
That is to say, since the dust collecting electrodes are only configured as flat plates and simply arranged in parallel, there is a problem that the dust collecting area in a certain space as a dust collecting device is small.
As a result, in order to ensure a certain dust collection capacity, the size of the device will increase and the performance will decrease.

no. 2 approach

[0107] Next, a second embodiment of the present invention will be described in detail with reference to the drawings.

[0108] like Figure 6 As shown, in this embodiment, the dust collecting electrode 40 is made of conductive metal instead of both the dust collecting electrode 40 and the high voltage electrode 50 being made of conductive resin in the first embodiment.

[0109] That is, the dust collecting electrode 40 is formed of a thin metal plate such as stainless steel, and the high voltage electrode 50 is formed of a conductive resin as in the first embodiment.

[0110] Like the first embodiment, the dust collecting electrode 40 is formed in a rectangular shape and includes a base part 41 and many protruding parts 42. Isolation part 45. Furthermore, the protruding member 42, the frame body 43, the vertical spacer 44, and the horizontal spacer 45 are each formed of a thin conductive metal plate.

[0111] As in the first embodiment, the protruding part 42 of the dust co...

no. 3 approach

[0115] Next, a third embodiment of the present invention will be described in detail with reference to the drawings.

[0116] like Figure 7 and Figure 8 As shown, in this embodiment, the corner portion of the tip of the protrusion member 52 of the high voltage electrode 50 is formed in an arc shape. Instead of forming the top corner of the protrusion member 52 of the high voltage electrode 50 at an acute angle in the first embodiment.

[0117] Specifically, the top corner of the protruding member 52 of the high voltage electrode 50 is formed in an arc shape when viewed from the end surface of the top end, and is also formed in an arc shape when viewed from the left and right sides, plan view, and bottom view, thereby forming a circular shape. Arc portion 52a.

[0118] According to this embodiment, since the tip corner portion of the protruding member 52 is configured as the arc portion 52a, residues such as burrs can be surely removed. As a result, abnormal discharge due...

no. 4 approach

[0121] Next, a fourth embodiment of the present invention will be described in detail with reference to the drawings.

[0122] like Figure 9 and Figure 10 As shown, in this embodiment, the charging unit 12 and the dust collecting unit 30 are integrally formed instead of the charging unit 12 and the dust collecting unit 30 being independently formed in the first embodiment.

[0123] Specifically, the charging unit 12 has a needle-shaped ionization electrode 12 a. The ionization electrode 12 a is integrally formed with the high voltage electrode 50 on the top end surface of the protrusion member 52 of the high voltage electrode 50 and extends forward. Moreover, the ionization electrode 12a is located inside the ventilation hole 46 of the dust collecting electrode 40, and is surrounded by the longitudinal spacer 44 and the transverse spacer 45 of the dust collection electrode 40, and a part of the longitudinal spacer 44 and the transverse spacer 45 constitute the opposite el...

Abstract

A dust collector includes a charging part (12) for charging dust with electricity and a dust collecting part (30). Each of a dust collecting electrode (40) and a high-voltage electrode (50) that constitute the dust collecting part (30) includes: a base (41, 51) with a rectangular grid structure having a large number of vent holes (46, 56) formed therein; and projections (42, 52) extending into the vent holes (56, 46) of the opposed electrode (50, 40). The dust collector collects dust by generating an electric field between the dust collecting electrode (40) and the high-voltage electrode (50).

Description

technical field [0001] The invention relates to a dust collecting device, in particular to an electrode structure. Background technique [0002] Conventionally, as disclosed in Patent Document 1, some of the dust collectors include a charging unit for charging dust, and a dust collecting unit having a dust collecting electrode and a high voltage electrode. The dust-collecting electrode and the high-voltage electrode of the dust-collecting part are composed of parallel plates, and the dust-collecting electrode is inserted between the high-voltage electrodes. [0003] The above-mentioned dust collecting device charges the dust in the air at the charging part, and generates an electric field between the dust collecting electrode and the high voltage electrode, and collects the dust charged at the charging part at the dust collecting part. [0004] Patent Document 1: Japanese Patent Laid-Open Publication No. 8-71451 [0005] However, since the dust collecting electrode and the...
