<p>PROBLEM TO BE SOLVED: To eliminate the charge of a dust collection part when the dust collection part is taken out. SOLUTION: The first contact 55 connected to a float electrode and the second contact 75 connected to the electrode on the low voltage side of a dust collection part 21 are provided to be arranged in the attaching direction R of a deodorizing filter 103. The deodorizing filter 103 is brought into contact with the second contact 75 and the first contact 55 in this order to short-circuit the first and second contacts 55, 75. By this constitution, even if charge is accumulated between the high voltage electrode and low voltage electrode of the dust collection port 21, accumulated charge can be eliminated.</p> |
