When the detected internal temperature T _1i of the drum 31 reaches the set temperature T _1S (S120), the drum 31 is rotated in a state in which the steam supply is stopped, so that the laundry is cooled and dried. The power of the heater 53 is turned off so that the so-called cold air drying may proceed (S130).

When a predetermined time elapses in the state in which the steam supply is stopped, the control unit 61 causes the timer 67 to calculate a driving time t _2i of the drum 31, that is, a cold air drying time (S140). When the driving time t _2i of the 31 reaches the set time t _2S (S150), the drum driving motor 33 is controlled to stop the driving of the drum 31 (S160). ) Is terminated.

Here, in a state in which the power supply of the heater 53 is turned off so that the supply of steam is stopped (S130), as shown in FIG. 5, the temperature T _2i inside the drum 31 by the temperature sensor 63. If (S135), the detected temperature (T _2i ) reaches the set temperature (T _2S ) (S145), the drive of the drum 31 is stopped (S150) may be configured to end the wrinkle removal process. .
