PROBLEM TO BE SOLVED: To prevent room temperature from rising due to oxidation and combustion of an odor component and fine particles by providing a heat generating part which heats a dust collecting/deodorizing part and a blower for circulating an indoor air into the dust collecting/ deodorizing part, and blowing the indoor air again into the indoor side when the heat generating part is not energized, and exhausting the indoor air to the outdoor side when the heat generating part is energized. SOLUTION: An indoor air (a) is taken from a suction aperture 12 by operation of a blower 11 to enable the passage of the indoor air (a) through a dust collecting/deodorizing part 9. In this case, the odor component (b) and fine particles (c) contained in the indoor air (a) are adsorbed by a dust collecting electrode plate 7 bearing the deodorizing catalyst 8 of the dust collecting/deodorizing part 9. In addition, the cleaned indoor air (a) is again returned to the indoor side from a damper 13. Further, at the point of time which a specified amount of dust is collected by the dust collecting electrode plate 7, a high temperature radiation heater 10 is energized and the collected odor component (b) and the collected fine particles (c) are oxidized and burned by a high temperature radiant heat, and further, the gas is exhausted to the outdoor side by the damper 13. When the indoor is warmed during the winter time, the damper 13 is inverted to the indoor side and an indoor side exhaust aperture 14 is opened when the high temperature radiation heater 10 is energized without supplying power to the dust collecting/deodorizing part 9. |
