Abstract: An air conditioner having an interior casing in which an air filter is provided along an inner face of an air suction inlet, includes a filter cleaning part, a cleaning time drive member for moving the air filter and the filter cleaning part with respect to each other, and an ultraviolet light irradiation unit which irradiates the air filter with ultraviolet rays. The air filter and the filter cleaning part are relatively moved by the cleaning time drive member to remove dust adhered to the air filter, and the ultraviolet light irradiation unit irradiates an uncleaned face of the air filter with the ultraviolet rays.

Abstract: In drying the interior of an indoor unit, room humidity (Rh) is detected by a humidity sensor, and a drying operation cycle, in which after first heating operation, which is weak heating operation in which a compressor included in a refrigerating cycle is operated at a low rotational speed, has been performed for a predetermined period of time, second heating operation, which is heating operation close to air blowing operation in which the compressor is stopped, is performed for a predetermined period of time, is repeated a predetermined number of times according to the room humidity (Rh). Thus, the indoor unit's interior can be dried properly without occurrence of dew condensation therein.
