The air inlet 102 of the ventilation channel 101 is provided at the top of the drying housing 1, and the air outlet 103 of the ventilation channel 101 is provided on its front side wall. During the subsequent installation process of this drying channel assembly with the washing machine, both the air inlet 102 and the air outlet 103 are communicated with the inner drum of the washing machine. The heated air circulates between the ventilation channel 101 and the inner drum of the washing machine, and the lint in the air will be filtered and blocked by the filter screen 2 to achieve the cleaning of the lint in the washing machine. Among them, the filter screen 2 is vertically arranged in the ventilation channel 101 and is located between the air inlet 102 and the air outlet 103.

[0033] Specifically, both the air inlet 102 and the air outlet 103 are communicated with the inner drum of the washing machine. The moist air in the inner drum passes through the ventilation channel 101 of the drying housing 1 and then returns to the inner drum of the washing machine to achieve circulation for drying clothes. During the process of passing through the ventilation channel 101 of the drying housing 1, the lint in the air is filtered by the filter screen 2. After long-term use, the filter screen 2 is prone to blockage, affecting the drying effect. At this time, the filter screen 2 can be cleaned by the brush cleaning component 3 to always maintain the filtering effect of the filter screen 2, and the lint after being cleaned can be discharged out of the washing machine through the lint outlet 104, improving the problem that the traditional method requires frequent disassembly and cleaning of the filter screen, which is very time-consuming and laborious.

[0034] Combined with the first aspect, in an implementation manner, as Figure 2 and Figure 3As shown, the brush cleaning assembly 3 may include: a cleaning brush 301, the cleaning brush 301 is rotatably connected to the inside of the drying housing 1, and the cleaning brush 301 is disposed in contact with the filter net 2; a driving motor 302, the driving motor 302 is installed on the drying housing 1 and is connected to the cleaning brush 301.

Among them, the plane where the cleaning brush 301 rotates is parallel to the plane where the filter net 2 is located. The driving motor 302 is installed on the outer wall of the drying housing 1. The output end of the driving motor 302 can penetrate into the drying housing 1 and is fixedly connected to the cleaning brush 301. The driving motor 302 can drive the cleaning brush 301 to rotate 90 degrees clockwise and counterclockwise to clean the lint on the surface of the filter net 2, and the lint swept off will be discharged through the lint outlet 104.

[0036] Combined with the first aspect, in one implementation, as Figure 2 and Figure 3 As shown, the brush cleaning assembly 3 may further include: a first gear 303, the first gear 303 is sleeved on the outer wall of the driving motor 302; a second gear 304, the second gear 304 is coaxially fixed with the rotating shaft of the cleaning brush 301, the second gear 304 meshes with the first gear 303, and the diameter of the second gear 304 is larger than the diameter of the first gear 303.

[0037] Exemplarily, the driving motor 302 and the cleaning brush 301 can be driven by transmission through the first gear 303 and the second gear 304. Specifically, the outer wall of the output end of the driving motor 302 is sleeved with the first gear 303. The rotating shaft is rotatably installed on the drying housing 1, and one end of it penetrates into the inside of the drying housing 1. The cleaning brush 301 is sleeved on the outer wall of one end of the rotating shaft, and the outer wall of the other end of the rotating shaft is sleeved with the second gear 304. The first gear 303 meshes with the second gear 304, and the diameter of the first gear 303 is smaller than the diameter of the second gear 304, which can reduce the rotation speed of the cleaning brush 301, improve the cleaning effect of the cleaning brush 301, and reduce the wear degree of the cleaning brush 301, thereby improving the service life of the cleaning brush 301.

[0038] Combined with the first aspect, in one implementation, as Figure 2 and Figure 3As shown, the brush cleaning assembly 3 further includes: a third gear 305, the third gear 305 is rotatably connected to the drying housing 1, the third gear 305 is engaged between the first gear 303 and the second gear 304, and the diameter of the third gear 305 is greater than the diameter of the first gear 303 and less than the diameter of the second gear 304.

[0039] Exemplarily, on the basis of the first gear 303 and the second gear 304, a third gear 305 is added.

Each type of brush filament has its advantages and disadvantages and is suitable for different cleaning scenarios and applications. For example, the brush filaments made of PET have the characteristics of rich colors, durability, impact resistance, and resistance to acid and alkali corrosion, and are suitable for many fields such as industrial sanitation brushes and household cleaning brushes. PET plastics, also known as polyethylene terephthalate plastics, mainly include polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), which are thermoplastic polyesters or saturated polyesters. They are commonly used to make mineral water bottles, beverage bottles, etc. Their heat resistance reaches 70°C, and they are not suitable for containing hot water or being heated and exposed to the sun, but they have good chemical corrosion resistance and are very suitable for making the cleaning brush 301.

[0044] In combination with the first aspect, in one embodiment, the ventilation channel 101 is connected to a water inlet pipe 4, and the debris outlet 104 is connected to a water outlet pipe 5.

[0045] Exemplarily, during the process of cleaning the filter net 2 by the brush cleaning assembly 3, water can be passed into the water inlet pipe 4.

[0048] Exemplarily, the fan can suck the humid air in the inner drum of the washing machine into the ventilation channel 101, which is dried and heated by the heating component. The air is condensed into water by the condensation exchanger component, and the water is finally discharged through the water outlet pipe 5. The air flows back into the inner drum through the air outlet 103, and this process is repeated to achieve clothes drying.

[0049] Further, the ventilation channel 101 is connected to a water inlet pipe 4, the water inlet pipe 4 is connected to the water inlet valve of the washing machine, the debris outlet 104 is connected to a water outlet pipe 5, and the water outlet pipe 5 is connected to the drain pipe of the washing machine.
