Zusammenfassung:The invention discloses a heat pump clothes dryer and a control method thereof. The control method of the heat pump clothes dryer comprises the following steps of: providing a drying cavity; controlling a gas leaving from the drying cavity to be discharged out of the heat pump clothes machine; judging whether the operation of the drying cavity accords with a preset condition or not; and if so, controlling the gas leaving from the drying cavity to return the drying cavity. In the invention, by using the switching of an opening duct and a closed duct, the energy utilization efficiency of the heat pump clothes machine is greatly improved.
