The water supply valve 6, the circulating water pump 7, the condenser 2, the compressor 1 and the evaporator 4 form a water heating circulation loop. When the heat pump clothes dryer enters the washing stage, hot water is supplied by means of the air source heat pump, sharing the compressor 1 and the evaporator 4 with the refrigerant circuit. Introducing high-temperature refrigerant of the compressor 1 into the condenser 2 to condense and release heat, flushing cold water into the condenser 2 through the circulating water pump 7 and the water supply valve 6, exchanging heat with high-temperature refrigerant steam, heating water temperature, and providing the water temperature for washing clothes; meanwhile, the inner circulation air valve 8 is closed, the outer circulation air valve 9 is opened, and the air channel of the evaporator 4 is switched, so that the evaporator 4 works in an outer circulation mode, and the normal operation of the heat pump system and the washing system is ensured.

otherwise, judging whether the monitored clothes temperature reaches the temperature corresponding to the current period of the drying stage;
if yes, reducing the opening degree of the throttle valve to maintain the exhaust temperature of the compressor in the current state;
otherwise the throttle opening is maintained or increased.
8. The control method of a heat pump clothes dryer system of claim 7, wherein: the method for switching the air duct of the evaporator by controlling the electric air valve to enable the evaporator to work in an internal circulation mode comprises the following steps of:
the method comprises the steps of switching an air duct of an evaporator by controlling an outer circulation air valve to be closed and an inner circulation air valve to be opened, so that the evaporator works in an inner circulation mode;
when the monitored humidity of the clothes reaches the humidity corresponding to the current period of the drying stage, the opening degree of the internal circulation air valve is kept or reduced;
when the monitored humidity of the clothes does not reach the humidity corresponding to the current period of the drying stage, if the monitored temperature of the clothes reaches the temperature corresponding to the current period of the drying stage, the opening degree of the internal circulation air valve is kept or reduced; and if the monitored temperature of the clothes does not reach the temperature corresponding to the current period of the drying stage, increasing the opening degree of the internal circulation air valve.
