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

Drum type drying and washing machine

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 (). The cleaning device () has a main body () pivotable about one end thereof relative to an outer bottom surface of the water tank, a brush () provided on the other end of the main body, and a bias spring () for biasing the main body toward an opening direction. The main body () is subjected to a dynamic pressure of water in the water tank and thereby pivots in an opening direction. When the main body () has the pivoting angle of 90&#xb0;, the brush () is in contact with the filter.
