Drum Type Drying and Washing Machine

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.
