Embodiment approach 1

[0127] 1 to 7 show an electric dust collecting unit according to Embodiment 1 of the present invention. As shown in FIGS. 1 to 7 , the electric dust collecting unit of the present invention has a plurality of needle-shaped electrodes 201 and needle-shaped electrode plates 202 arranged in parallel at equal intervals. Further, there are plate-shaped parallel electrodes 203 parallel to the needle-shaped electrode plate 202 and arranged at equal intervals; and plate-shaped apertured electrodes 204 supporting the parallel electrodes 203 ; Further, facing the tip portion 205 of the acicular electrode 201 , the apertured electrode 204 is provided on the downstream side, and the parallel electrode 203 and the apertured electrode 204 are arranged in a nearly U-shape so as to surround the acicular electrode 201 .

[0128] In addition, "U" itself has a straight line part and a curved line part. However, the "U-shape" described in the present invention is not necessarily limited to such ...

Embodiment approach 2

[0141] 8A and 8B show electrodes of the electric dust collecting unit related to the second embodiment. As shown in FIGS. 8A and 8B , a dust collecting filter 208A or a deodorizing filter 209A is provided on the downstream side in contact with the apertured electrode 204A.

[0142] As shown in FIG. 8A, when the dust collection filter 208A is provided in contact with the downstream side of the apertured electrode 204A, charged dust can be collected by discharging from the tip 205 of the needle electrode 201 to which a high voltage is applied. .

[0143] As shown in FIG. 8B , when a deodorizing filter 209A is provided in contact with the downstream side of the apertured electrode 204A, by discharging from the tip 205 of the needle-shaped electrode 201 to which a high voltage is applied, it is possible to collect charged At the same time as the dust, the odor components are captured, and the dust collection efficiency is improved while performing the deodorizing function.

Embodiment approach 3

[0145] 9A and 9B show electrodes of the electric dust collecting unit according to the third embodiment. As shown in FIGS. 9A and 9B , the dust collecting filter 208B or the deodorizing filter 209B provided on the downstream side of the apertured electrode 204B is configured to have conductivity.

[0146] In FIG. 9A , when a conductive dust collection filter 208B is provided in contact with the aperture electrode 204B, the entire surface of the dust collection filter 208B can be brought to a ground potential. As a result, charged dust is collected by the dust filter 208B by discharging from the tip portion 205 of the needle electrode 201 to which a high voltage is applied, and the dust collection efficiency is improved.

[0147] In FIG. 9B , a conductive deodorizing filter 209B is provided in contact with the apertured electrode 204B. In such a case, the entire surface of the deodorizing filter 209B can be grounded. Accordingly, charged dust and odor components contained in ...

Abstract

An electric dust-collecting unit having improved dust collecting performance and thinned. The electric dust-collecting unit has needle-like electrodes (201) each having a sharp tip section (205) in the downstream direction, parallel electrodes (203) arranged in parallel to the needle-like electrodes (201), and open electrodes (204) provided on the downstream side, facing the sharp tip sections (205) of the needle-like electrodes (201). The parallel electrodes (203) and the open electrodes (204) are disposed in a substantially U shape so as to surround the needle-like electrodes (201). Discharge from the needle-like electrodes (201) to the opposite electrodes is made in many directions, which improves dust-collecting performance. Further, the needle-like electrodes (201) can be placed close to the open electrodes (204), so that the electric dust-collecting unit can be thinned.

Description

technical field [0001] The present invention relates to an electric dust collector installed in an air flow path of an air conditioner or the like to remove dust and the like contained in the conditioned air. Background technique [0002] Conventionally, it is well known that needle-shaped discharge electrodes are provided in the conventional electric dust collecting unit of this type (for example, Japanese Patent Application Laid-Open No. 2003-10731, see FIG. 1 ). [0003] Hereinafter, this electric dust collecting unit will be described with reference to FIG. 31 . [0004] As shown in FIG. 31 , a needle-shaped discharge electrode 104 is provided on the suction port 101 side of the filter frame 103 in which the suction port 101 and the blowing port 102 are formed. Opposite to the discharge electrode 104, an air-permeable ground electrode 105 such as lath or punching metal is provided in the air outlet 102 of the filter frame 103. A filter 106 is provided on the wind downs...
