When the laundry is wet, the temperature does not easily rise. Therefore, the drying time can be reduced by increasing the input of the heater 16 and increasing the drying temperature in the inner tub 4. Conversely, in the latter half of drying, the laundry tends to dry and the temperature tends to rise. Therefore, by lowering the drying temperature, damage and shrinkage due to high temperature can be reduced.

Further, when hot air of approximately 60 ° C. is blown into the inner tank 4 in the drying process of the “drying course for heat-sensitive clothes”,
The degree of drying of the laundry in the inner tub 4 is detected by the drying detecting means 38, the drying step is divided into a plurality of steps, and the drying temperature is set to a high temperature (for example, about 75 ° C.) in the previous step.
