[0051] In the prior art, even if a filter device is arranged on the ventilation air duct, the lint cannot be completely removed, and a part of the extremely fine lint passes through the filter screen holes of the filter device, continues to flow with the airflow, and still affects the operation stability and service life of the heat pump system. In the present embodiment, the electrostatic filter 700 arranged at the downstream side of the lint filter assembly can adsorb the part of the fine lint leaked on the surface of the electrostatic filter 700, thereby more effectively eliminating the influence of the lint on the heat pump system compared with the prior art.

[0052] As one of the optional embodiments, the electrostatic filter 700 includes an electrostatic generator and an electrostatic adsorption structure, the electrostatic generator is connected with the electrostatic adsorption structure, and is used to make the electrostatic adsorption structure generate static electricity, and the electrostatic adsorption structure is arranged in the form of a grid in the air duct at the downstream side of the lint filter assembly. The electrostatic adsorption is simple and reliable, and can effectively remove the lint, and the electrostatic adsorption structure arranged in the form of a grid can effectively expand the influence range of the electrostatic adsorption, preferably, the electrostatic adsorption structure covers the cross section of the air duct, which makes all the hot air need to pass through the electrostatic adsorption structure, and in this process, the lint in the hot air is adsorbed on the electrostatic adsorption structure, thereby effectively removing the lint.

[0053] In another embodiment, as shown in Figures 1-11 The lint filter assembly includes a lint box, the lint box includes two or more filter parts, the filter parts are arranged in sequence to form a plurality of filter cavities, and optionally, a filter sponge is arranged at the downstream side of the lint box, and the filter sponge is used to filter the fine lint passing through the filter parts.

[0054] In the prior art, during the drying process, the hot air in the clothes dryer is recycled to reduce energy consumption and improve drying efficiency. However, a large amount of lint is generated during the drying process of the fabric, and the lint attached to the condenser and heat exchanger with the circulation of hot air seriously affects the heat exchange efficiency. It is also necessary to set corresponding cleaning devices for the condenser and heat exchanger, which affects the sealing performance of the air duct on the one hand, and makes the structure of the clothes dryer more complex and the equipment cost higher on the other hand. In the present application, by providing two or more filtering parts, the lint content in the hot air can be greatly reduced. By providing a filtering sponge with extremely small pore size and variable pore direction, the fine lint after passing through the two filtering parts can be effectively removed, significantly improving the lint removal efficiency, maintaining the cleanliness of the condenser and evaporator surface, and ensuring the air tightness of the drying air duct, thereby improving the drying efficiency. It should be noted that the filtering sponge is arranged downstream of the lint box, that is, the filtering sponge is arranged in the drying air duct downstream of the lint box and / or at the air outlet of the lint box.

A plurality of filter screens are arranged on the first filtering part 100 and the second filtering part 200, respectively. Through the above arrangement, the airflow passing through the fabric treatment cavity is directly introduced into the first filtering cavity, and then sequentially passes through the second filtering cavity and the third filtering cavity, and then enters the drying air duct, thereby forming a three-layer filtering structure to effectively collect the lint in the lint box. On this basis, the fine lint passing through the above filtering cavities can be filtered by the filtering sponge downstream, thereby effectively preventing the lint from escaping into the heat pump system, and significantly improving the working efficiency and service life of the heat pump system. It should be noted that the third filtering part 300 can be provided with a filter screen or not, which can be determined according to the subsequent arrangement of the filtering sponge, and is not limited herein.
