Drying is carried out by sending it inside. The high-temperature and high-humidity air containing moisture evaporated from the wet laundry in the drum 2 passes through the exhaust port 32 of the water tub 4, passes through the exhaust duct 19, and enters the cooling duct 8. Moisture condenses due to heat exchange when the jet of cold water supplied through the water supply valve 7 for drying comes into contact with the moisture. The cooled dry air is sent to the blower fan 20 again, and is recirculated to the drum 2 reheated by the heater 29.

うものである。In the sixth embodiment of the drum type washing and washing machine of the present invention, as shown in the flow chart of FIG. 7, cold water is injected by the drying water supply valve 7 during the drying step. Since the drain path is closed by the drain valve 12, water gradually accumulates in the water tank 4. If a large amount of water accumulates, water is supplied to the clothes in the drum 2 or the drying performance is affected. Therefore, the drain valve 21 is opened to drain water appropriately. That is, the water level sensor 25 detects the water level and controls the operation of the drain valve 12 so that the opening of the water supply pipe 61 is kept closed by the water.

流入しないような抵抗が設けてある。In the second, third and fourth embodiments of the drum type washing machine according to the present invention, when the washing water supply valve 6 fails, water is supplied into the water tub 4 and the water level rises. Accordingly, the water surface in the water supply pipe 61 also rises and rises to the branch portion, and flows into the overflow pipe 64. Since the overflow pipe 64 is connected to the drain hose 13, it is drained directly to the outside of the machine. Further, in the third and fourth embodiments, a resistance is provided so that the water does not flow into the overflow pipe 64 except in the above-described state in normal water supply.
