In this embodiment, the door lock acceptance time is set to 1 minute, and door lock acceptance is limited to the period from the start of the drying operation to the elapse of the door lock acceptance time. When the control unit 60 determines that the door lock acceptance time has not elapsed, the process returns to step S5. When the control unit 60 determines that the door lock acceptance time has elapsed, the process proceeds to step S8.

In step S8, since the door lock acceptance time has elapsed since the start of the drying operation, the control unit 60 ends the door lock acceptance and turns off the LED 54 to indicate that the door lock acceptance has been completed. In this embodiment, if the user does not lock the door until the door lock acceptance time has elapsed, the drying operation is continued in a state where the door is not locked (a state where the door 12 can be opened).

In step S9, the control unit 60 determines whether the drying operation time corresponding to the fee invested by the user has elapsed since the start of the drying operation. When the control unit 60 determines that the drying operation time has not elapsed, the process of step S9 is repeated. When the control unit 60 determines that the drying operation time has elapsed, the process proceeds to step S10.

In step S10, since the drying operation time has elapsed, the control unit 60 controls the motor driving unit 64 to stop the rotational driving of the drum 5, and ends the drying operation.

In step S11, the control unit 60 determines whether the user has locked the door lock when the drying operation is started. When the control unit 60 determines that the door lock is locked when the drying operation is started, the process proceeds to step S12. At this time, the door 12 is locked by the door lock device 50. In order to open the door 12, it is necessary to use the password set by the user to unlock.

In step S11, when it is determined by the control unit 60 that the door lock is not locked when the drying operation is started, the process proceeds to step S15.

In step S12, the control unit 60 determines whether the unlocking of the door lock by the user has been completed. When the control unit 60 determines that door lock unlocking has been completed, the process proceeds to step S13. When the control unit 60 determines that door lock unlocking has not been completed, the process proceeds to step S14.

It should be noted that "door lock unlocking completion" means that the user operates the password setting dial 55 of the door lock device 50 to display the password set at the start of the drying operation, and operates the door lock device 50 53 to move the lock hook 52 from the locking position to the unlocking position.

In step S13, since the user has unlocked the door lock, the control unit 60 unlocks the door lock and makes the door 12 openable. At this time, the control unit 60 turns off the LED 54 .

In step S14, the user has not unlocked the door lock. Therefore, the control unit 60 does not unlock the door lock and maintains the state that prevents the door 12 from opening. At this time, the control unit 60 maintains the LED 54 in the lighting state.
