Abstract:
1. A clothes drying apparatus comprising: a heat pump mechanism including a compressor, a heat radiator for radiating heat of a compressed coolant at a high pressure and a high temperature, a throttle unit for depressurizing the high-pressure coolant, and a heat absorber for absorbing heat from surroundings by using the depressurized low-pressure coolant, wherein the compressor, the heat radiator, the throttle unit and the heat absorber being connected to each other by a pipeline to allow the coolant to be circulated; a rotary drum rotatably driven by a motor; an air path for guiding drying air to the rotary drum, the heat radiator, and a drying drum having therein clothes; a blower for blowing the drying air to the air path by a separate motor which is different from the motor driving the rotary drum; a controller for controlling driving of the compressor; and a drying operation stop switch for resuming and suspending a drying operation, wherein the controller operates the blower, the rotary drum, and the compressor during the drying operation, and reduces an air draft of the blower or stops blowing and stops the rotary drum and the compressor in case the drying operation is suspended by manipulating the drying operation stop switch; and in case of resuming the drying operation by manipulating the drying operation stop switch, the controller enables the blower to increase its air draft or start blowing and operates the rotary drum, and enables the compressor to be operated only after a delay time period t
