The invention provides a washing drying machine which can utilize the condenser of the heat pump to generate hot water and prevent icing in the condition that the water remains in the feed line for through the hot water generated in the condenser. The washing drying machine comprises a condenser (21) guiding the water to flow from the feed valve to the heat pump, a feed line supplying the sink (2)from the affusion tank (38) after heat exchange. An air open pipe (49) opening for air is set between the feed line (42) and the feed valve (39). If the second drain valve is open, the air can flow into the feed line (42) through the air open pipe (49) and the water remaining in the feed line (42) can be drained to the third drain pipe (45) easily.
