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] In the prior art, it is well known that needle-shaped discharge electrodes are provided in the existing electric precipitating unit (for example, Japanese Patent Publication, Unexamined Patent Publication No. 2003-10731, refer to figure 1 ).

[0003] Below, refer to Figure 31 This electric dust collecting unit will be described.

[0004] Such as Figure 31 As shown, 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 wi...
