Abstract
A drum type washing-drying machine includes an air supply opening and an air discharge opening both located in a water tub, a circulation path having both ends connected to the air supply opening and the air discharge opening respectively, and branch paths located between a part of the circulation path where the condenser is located and the air supply opening and/or extending in another part of the circulation path between the evaporator and the air discharge opening. Either air supply or discharge opening is located in an upper part of the water tub front. The circulation path includes a heat exchange section where a condenser and an evaporator are disposed so as to be located below the water tub. The branch paths extend from either air supply or air discharge opening, through a periphery of the opening of the water tub front to the heat exchange section.
