[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] The embodiments of the present application provide a filtering device and a clothing processing device to solve the problem that the drying channel of the existing washing machine is easily clogged by impurities such as lint, which will be described below in conjunction with the accompanying drawings.

[0041] The filtering device provided in the embodiment of the present application is applied to a clothes processing device, the clothes processing device includes a drying channel, the drying channel includes an air outlet, see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the filtering device provided in the embodiment of the present application. Figure 2 The exploded view of the filtering device provided in the embodiment of the present application comprises a housing 1, a shower head 2 and a filter element 3. The housing 1 is provided with an air duct 11 along the first direction, the air duct 11 is connected to the air outlet, the housing 1 is provided with a flow channel 12 along the gravity direction, the flow channel 12 and the air duct 11 intersect to form a filtering space; the shower head 2 is arranged at the top of the flow channel 12 along the gravity direction; the filter element 3 is rotatably installed in the filtering space, the filter element 3 comprises a filtering surface 31, the filtering surface 31 comprises a filtering state in which the filter surface 31 is rotated to cover the air duct 11 to filter the fluff, and a cleaning state in which the filter surface 31 is rotated to cover the shower head 2 to be rinsed. It is understandable that the end of the shower head 2 facing away from the flow channel 12 is connected to a water source. The relative angle between the first direction and the gravity direction is not further limited here. In some examples, the first direction may be perpendicular to the gravity direction.

[0042] The filtering device provided in the embodiment of the present application has an air duct 11 connected to the air outlet end of the drying duct of the clothing processing equipment. When the air blown out from the drying duct passes through the filter element 3 in the air duct 11, impurities such as lint carried in the air flow are adsorbed on the filter surface 31. When the washing program is finished, the filter surface 31 rotates to the mask spray head 2, and the spray head 2 discharges water to the filter surface 31 to rinse the filter surface 31. There is no need to manually clean the filter element 3, so that the collection of lint in the drying duct and the self-cleaning of the filter element 3 are realized, thereby improving the automation performance of the clothing processing equipment.

[0043] Optionally, the air duct 11 includes an air inlet and an air outlet, the air inlet is communicated with the air outlet end of the drying duct, and the air flow in the drying duct flows from the water inlet of the air duct 11 to the air outlet.

[0044] Optionally, see Figure 3 , Figure 4 and Figure 5 , Figure 3 for Figure 1 A cross-sectional view at AA in one state. Figure 4 for Figure 1 The cross-sectional view at AA in another state, Figure 5 for Figure 1In another cross-sectional view at the middle BB in another state, the filter element 3 also includes a first shielding surface 32, which is connected to the filtering surface 31; wherein, when the filtering surface 31 rotates to cover the air duct 11, the first shielding surface 32 shields the spray head 2; when the filtering surface 31 rotates to cover the spray head 2, the first shielding surface 32 shields the air duct 11.

[0045] That is, when the filter element 3 rotates to the point where the filter surface 31 covers the air duct 11, the first shielding surface 32 covers the flow channel 12 to shield the spray head 2, thereby preventing the fluff from entering the spray head 2 and clogging the spray head 2 when the filter device collects fluff in the airflow through the filter surface 31. The spray head 2 is protected by the first shielding surface 32; when the filter element 3 rotates to the point where the filter surface 31 covers the flow channel 12, that is, covers the spray head 2, the first shielding surface 32 covers the air duct 11, so that when the spray head 2 discharges water to the filter surface 31 to rinse the filter surface 31, the first shielding surface protects the air duct 11 to prevent water from splashing into the air duct 11, thereby maintaining the cleanliness of the air duct 11 when the filter element 3 is clean.

[0046] In some examples, the first shielding surface 32 and the filtering surface 31 may both be arc surfaces, and the central angles of the arc surfaces are both 90°.

[0048] That is, the flow channel 12 or the air channel 11 is shielded and protected by the second shielding surface 33 and the first shielding surface 32. When the filter surface 31 is in a filtering state where fluff is collected, the first shielding surface 32 protects the shower head 2 to prevent the shower head 2 from being blocked by fluff, and the second shielding surface 33 protects the water outlet 121 to prevent the water outlet 121 from being blocked by fluff. When the filter surface 31 is in a cleaning state where the shower head 2 is flushed, the first shielding surface 32 and the second shielding surface 33 are relatively located in the air channel 11 to prevent water in the flow channel 12 from flowing into the air channel 11, thereby ensuring the cleanliness of the air channel 11.

[0054] By providing the retaining ribs 34 , fluff is prevented from entering the flow channel 12 through the gap between the filter element 3 and the flow channel 12 , or water is prevented from entering the air channel 11 through the gap between the filter element 3 and the air channel 11 .

[0055] Optionally, a drainage channel 13 is further provided in the housing 1, one end of the drainage channel 13 is connected to the water outlet 121, and the other end is used to drain water to the outside of the clothing processing device.

The waste liquid washed in the flow channel 12 is collected through the drainage channel 13.

[0056] Optionally, the cross section of the filter element 3 is arc-shaped, so the filter element 3 will not interfere with the flow channel 12 or the air duct 11 when rotating, and the corresponding cross section of the filter space is circular. It should be noted that the cross section is the cross section obtained by the plane perpendicular to the rotation direction of the filter element 3 and the filter element 3.
