<p>PURPOSE:To shorten a high voltage wiring by providing a pair of power source connection terminals in the positions near a high voltage power source of a filter frame and also providing the lead-out terminals of electrodes of the respective high/low electric potential sides in the air cleaning filters adjacent thereto and connecting the electrodes to the respective power source connection terminals. CONSTITUTION:A pair of respective electrodes 3a, 3b; 4a, 4b of the high/low electric potential sides for imparting potential difference and a pair of respective lead-out terminals 5a, 5b; 6a, 6b thereof are provided respectively in the insides of left and right filters 1, 2. On the other hand, the respective connection terminals 8a, 8b are provided in a filter frame 7 which freely detachably holds the left and right filters 1, 2. The lead-out terminals 5a, 5b; 6a, 6b are connected to the connection terminals 8a, 8b in common. DC high voltage is supplied to the respective connection terminals 8a, 8b via a high voltage electric wire 1Oa and an earth electric wire 10b from a high voltage power source 9. In the above constitution, a pair of power source connection terminals 15a, 15b are provided in the vicinity of the high voltage power source 9 in the filter frame 7. Further, a second lead-out terminals 16a, 16b of electrodes of high/low electric potential sides are provided in the right filter 2 adjacent to the respective connection terminals 15a, 15b. The electrodes are connected to the connection terminals 15a, 15b.</p> |
