Abstract

PURPOSE:To make a fitting space unnecessary and save time for the replacement of a cassette by connecting a suction box equipped with a folding cassette-type dust collecting filter and a blow-out box by a duct tube, both boxes being buried in the ceiling. CONSTITUTION:An electrode fixing plate 8 is provided inside a suction box 1 whose bottom has an opening, a blowing fan 9 is fitted on this side of a duct hole 7, and a closed airing route is formed between the blowing fan 9 and the duct hole 7, the device thus formed being connected with a blow-out box 2 by a duct tube 3. In addition, an air cleaning device is accommodated in the suction box 1. This device is formed by erecting high-voltage points 12 each having an ionizing point 10 at its tip and thereby collecting charged corpuscles and arraging folding dust- collecting filters 11 between them. By this, the dirty air around the ceiling is electrified positively by the ionizing point 10 and set at the dust-collecting filter 11, and thus the cleaned air alone enters the box 2, being returned into a room.
