PURPOSE:To alleviate an unpleasant feeling due to the re-release of rancidity even after a dust collecting filter is used for a long time by providing a fiber for sucking a liq. deodorant in a liq. deodorant tank to be supplied to the filter. CONSTITUTION:Indoor air is sucked from an air suction grill 1, passed through the dust collecting filter 2 of a filter set 8, and cleaned. The cleaned air is discharged from a blowoff grill 15 by the action of an impeller 13. In this case, the liq. deodorant 6 stored in the liq. deodorant tank 3 is sucked up by the capillarity of the sucking fiber 5, the dust collecting filter 2 is impregnated with the deodorant 6 by contact with the fiber 5, the rancidity in the sucked air is absorbed by the deodorant, fragrance is developed to mask the rancidity, and the re-release of the rancidity absorbed by the filter 2 is controlled. |
