DETAILED DESCRIPTION

[0034] At present, the drying channel assembly of the washing machine lacks a cleaning function, which makes it easy for lint, dust and other debris to accumulate at the impeller, making it difficult for the impeller to stir the airflow, reducing the gas flow efficiency in the drying channel space, thereby reducing the drying effect of the drying channel assembly. The present disclosure provides a drying channel assembly and a washing machine to solve the above problems.

[0035] like Figure 1 and Figure 2 As shown, the present disclosure provides a drying tunnel assembly, including a housing 2 and an impeller (not shown in the figure). The housing 2 is provided with a drying tunnel space (not shown in the figure) and a flow channel 200. The water inlet 201 of the flow channel 200 is connected to the outside of the housing 2. The water outlet 202 of the flow channel 200 is connected to the drying tunnel space. The water outlet 202 faces the impeller.

[0036] By providing the flow channel 200 on the housing 2, the drying tunnel assembly can clean the impeller, avoid the accumulation of lint, dust and other debris on the impeller, and keep the impeller clean. The clean impeller can stir to generate a larger airflow, and the air flow efficiency in the drying tunnel space is improved, thereby improving the drying effect of the drying tunnel assembly. The number of water outlets 202 can be multiple to further improve the cleaning effect of the drying tunnel assembly on the impeller. The water outlet 202 can achieve spraying on the impeller by means of pressure relief.

[0037] The present disclosure also provides a washing machine, comprising a drainage component and the above-mentioned drying tunnel assembly. The drying tunnel space is connected to the drainage component. Since the drying tunnel assembly of the present disclosure has a good drying effect, the washing machine of the present disclosure has a good user experience.

[0038] At the same time, since the drying tunnel space is connected to the drainage component, the water flow that has washed the impeller can be directly discharged through the drainage component of the washing machine itself, without the need to set up an additional drainage channel. The structure is simple, the cost is low, and it will not affect the existing structural platform. The washing machine disclosed in the present invention can be a condensing washing and drying machine, and the specific type of washing machine is not limited. The drainage component can be a washing tub 10 or a channel of a condenser. The washing tub 10 can be the outer barrel of the washing machine. The specific type of the drainage component is not limited.

[0039] The washing machine of the present disclosure can circulate hot air to further improve the drying efficiency of clothes. When the drainage component is a washing tub 10, the drying channel assembly generates hot air and blows it into the washing tub 10. Since the drying channel space is connected to the inside of the washing tub 10, the hot air in the washing tub 10 will pass through the drying channel assembly again, and then be blown into the washing tub 10 after being heated, so as to realize the circulation of hot air. When the drainage component is a channel of a condenser, the air in the washing tub 10 passes through the condenser to be heated, and then is heated by the drying channel assembly, and finally is blown back into the washing tub 10, so as to realize the circulation of hot air.

[0040] like Figure 1As shown, the washing tub 10 may include a tub body 11, a connecting column 12 and a reinforcing rib 13. The connecting column 12 extends from the tub body 11 in a vertical direction, and the reinforcing rib 13 connects the tub body 11 and the connecting column 12. The connecting column 12 is used to connect the housing 2. The reinforcing rib 13 is used to improve the strength of the connecting column 12, thereby improving the installation strength of the housing 2.

[0049] The buckle structure 224 can be disposed on the second wall 222, and the hook structure 235 can be disposed on the flange 232. The buckle structure 224 can be formed by a pair of claws. The hook structure 235 can be formed by extending from the flange 232 toward one end, and the hook structure 235 is installed between the pair of claws. The number of the buckle structures 224 can be three, which can be distributed at intervals along the circumferential direction. Correspondingly, the number of the hook structures 235 is also three, which are also distributed at intervals along the circumferential direction.

[0050] The flow channel portion 22 may be provided with a first fixing ear 225, and a fixing groove 2251 is provided on the first fixing ear 225.

[0051] like Figure 5As shown, in this embodiment, the inner wall of the housing 2 is provided with a water outlet nozzle 204. The water outlet nozzle 204 forms a water outlet 202. The water outlet nozzle 204 includes a guide plate 2041, and the extension direction of the guide plate 2041 is inclined toward the impeller relative to the axial direction of the drying tunnel space. By providing the guide plate 2041, the water flow can be more accurately guided to the impeller, thereby improving the cleaning effect of the drying tunnel assembly on the impeller.

[0052] In another embodiment, if Figures 6 to 8 As shown, the flow channel portion 22 may include a third wall 226 protruding from the outer surface of the bracket body 21 in a direction away from the bracket body 21.
