PURPOSE:To smoothly perform the deodorizing treatment by ozone by combining an ozone generator and a catalyst to form an ozone generating cassette, and replaceably arranging the cassette in an ozone treatment passage. CONSTITUTION:An ozone generator 15 is arranged near the lower side of a fan passage case 13 in an ozone passage case 14, and a catalyst 16 is arranged on the lower side of an ozone treatment passage S. The ozone generator 15 is constituted of an ozonizer 17 and a heater 18, the ozonizer 17 is connected to a high-voltage generator 19 provided on the outside face of the ozone passage case 14, the generator 19 is connected to a controller I, and high voltage is applied to the ozonizer 17 from the high-voltage generator 19 based on the drive output from the controller I to generate ozone. When the ozone generating cassette C of the ozone passage case 14 provided with the ozonizer 17 and the catalyst 16 is to be replaced, the ozone passage case 14 connected to a fan passage case 13 is removed, a new ozone generating cassette C is fitted to the case 14, and the replacement can easily be performed with only a one push operation. |
