The discharge line 103 and the parallel electrode plate 104 are sequentially arranged from the suction port 102.
The charging unit 105 including is installed. Charging part 10
In No. 5, a high voltage power source connects + to the discharge line 103 and − to the parallel electrode plate, and a voltage is applied to cause corona discharge in the charging unit 105. The air containing dust is charged by the charging unit 105.
The dust is charged to + by the corona discharge as it passes through. An electric field is generated in the electrode plate of the dust collecting portion 106 that is alternately connected to the electrode plate by + and − by the high voltage power source, and the dust charged to + is collected by the negative electrode plate.
The cleaned air is blown out from the air outlet 107.
