At the same time, the outer cylinder cylinder mouth 201 is connected with a clothes feeding port 20 opened on the shell 1 through an annular window gasket 6, so that a channel for taking and placing clothes is formed between the clothes feeding port 20 and the outer cylinder cylinder mouth 201 through the annular window gasket, which only connects the outer cylinder with the outside and isolates the space between the outer cylinder and the shell. In addition, a door body 7 which can be opened outward is installed at the front end of the washing machine shell 1, the door body 7 is arranged corresponding to the opening and closing of the clothes feeding port 20 of the shell 1, and is used to achieve the corresponding closing or opening of the outer cylinder cylinder mouth 201 by opening and closing the door body 7.

[0036] In the embodiment of the present application, the clothes treatment device further comprises: a drying system for drying treatment of the load in the drum to obtain dry clothes and the like, thereby achieving the effect of improving the quality of life of the user.

[0037] In the embodiment of the present application, the drying system comprises an air duct 5 which is communicated with the outer drum 2 at both ends to form a circulating air path; a fan 10 is installed in the air duct 5, so that the circulating air path formed by the outer drum 2 and the air duct 5 forms a circulating airflow flowing in a single direction; a dehumidifying unit for dehumidifying the circulating airflow flowing therethrough is also installed in the air duct 5 to achieve the effect of reducing the humidity of the airflow in the circulating air path and drying the load in the drum 3; at the same time, in order to improve the drying rate of the load in the drum 3 and accelerate the vaporization of the water adsorbed in the load, a heating unit 11 can be arranged in the air duct 5 to heat the circulating airflow flowing therethrough, thereby achieving the effect of improving the temperature in the outer drum 2 and accelerating the drying rate by heating the load in the drum 3.

The heat pump system consists of a compressor, evaporator, throttling device, and condenser connected sequentially to form a circulating flow channel for the cooling medium. A condenser and evaporator are installed sequentially along the direction of the circulating airflow in the air duct 5 of the clothes handling device. This allows the airflow from the outer drum 2 to first exchange heat with the evaporator, condensing and separating the water vapor it contains. Then, it exchanges heat with the condenser again to heat and form a high-temperature dry airflow. Finally, the high-temperature dry airflow flows back into the drum 3, thereby reducing the humidity in the drum and increasing the temperature in the outer drum 2, thus achieving the effect of drying the load in the drum 3. Therefore, the evaporator of the heat pump system is configured as a dehumidification unit 9, and the condenser as a heating unit 11, to achieve the effect of drying the load in the drum 3.
