Abstract: A drum type washing and drying machine has a water tank (4), a rotary drum rotatably provided in the water tank (5), a dehumidifying heat exchanger for dehumidifying air introduced from inside of the rotary drum (5), a heater unit for heating the air dehumidified by the dehumidifying heat exchanger, and a blower (131) for introducing the air in the rotary drum (5) into the dehumidifying heat exchanger and delivering into the rotary drum (5) the air heated by the heater unit. A filter (160) is placed in a suction-side channel between the rotary drum (5) and the blower and on an upstream side of air flow produced by the blower (131) in a drying process. The filter (160) is placed so as to be soaked in water supplied into the water tank in a washing process or in a rinsing process.

Abstract: A washer-dryer apparatus has a blower for sucking air from a water tank and blowing the air into a washing and dewatering tub. At an inlet of the blower is provided a filter, which is cleaned by a cleaning device (300). The cleaning device (300) has a main body (301) pivotable about one end thereof relative to an outer bottom surface of the water tank, a brush (302) provided on the other end of the main body, and a bias spring (303) for biasing the main body toward an opening direction. The main body (301) is subjected to a dynamic pressure of water in the water tank and thereby pivots in an opening direction. When the main body (301) has the pivoting angle of 90°, the brush (302) is in contact with the filter.
