Abstract: A drum-type washer/dryer having an evaporator for performing dehumidification by cooling air drawn from the inner space of a drum and also having condenser for heating the air dehumidified by the evaporator, wherein the air heated by the condenser is made to sequentially pass through a duct and a blowhole and blown as dry air to clothes in the drum. A backflow preventing portion is provided in the duct, and when bubbles flow back into the duct from the inner space of the drum through the blowhole, the backflow preventing portion functions as resistance for preventing the back flow of the bubbles.

Abstract: A drum-type washer/dryer having an evaporator (34) for performing dehumidification by cooling air drawn from the inner space of a drum (24) and also having condenser (35) for heating the air dehumidified by the evaporator (34), wherein the air heated by the condenser (35) is made to sequentially pass through a duct (40) and a blowhole (47) and blown as dry air to clothes in the drum (24). A backflow preventing portion (52) is provided in the duct (40), and when bubbles flow back into the duct (40) from the inner space of the drum (24) through the blowhole (47), the backflow preventing portion (52) functions as resistance for preventing the back flow of the bubbles.

Abstract: A drum washing machine includes a water tub (10), a rotating tub (14) mounted in the water tub (10) to be rotated about a transverse axis, an elastic support (11) for elastically supporting the water tub (14), and an auxiliary baffle (23) formed on the inner peripheral wall of the rotating tub (14) so as to be close to one of the end plates of the rotating tub and away from the other end plate of the rotating tub (14). The auxiliary baffle (23) extends in a direction of axis of the rotating tub (14). The auxiliary baffle (23) moves laundry in the rotating tub (14) near a center of gravity of a member of vibration system applying load to the elastic support (11).

Abstract: A washing machine with a drying function includes a water tub, a rotating tub mounted in the water tub so as to be rotatable, a driver rotating the rotating tub, a circulation passage defined so as to communicate with the water tub, a warm-air supply unit circularly supplying warm air through the circulation passage into the water tub and the rotating tub, a water-supply unit supplying water into the water tub, a control unit controlling the driver, the warm-air supply unit and the water-supply unit thereby to be capable of controlling wash, rinse, dehydration and drying steps, and a preheating unit executing a preheating operation in which warm air is supplied into the water tub and the rotating tub during rotation of the rotating tub before the wash step is executed.
