[0049] The clothing processing equipment 100 provided in this application embodiment can be a dryer or a washer-dryer combo. When the clothing processing equipment 100 is a washer-dryer combo, it can wash and dry clothing.

[0050] Please see Figure 2 The clothing processing device 100 provided in this application embodiment includes an outer shell 10 and a tubular part 20. The tubular part 20 is disposed inside the outer shell 10, and the clothing to be cleaned can be put into the tubular part 20 for cleaning.

[0051] See some examples. Figure 2 The garment processing equipment 100 also includes a shock absorber 30. The tubular part 20 is supported inside the outer shell 10 by the shock absorber 30. The shock absorber 30 can alleviate the severe vibration and impact generated by the garment processing equipment 100 during washing and dehydration, ensure the stable operation of the garment processing equipment 100, and reduce noise and extend service life.

[0052] See some examples. Figure 2 The garment processing equipment 100 also includes a drying device 40, which provides hot air into the tubular section 20 to dry the garments inside. Specifically, a drying duct is formed between the tubular section 20 and the drying device 40. The hot air generated by the drying device 40 can flow into the tubular section 20 through the drying duct, and the humid air inside the tubular section 20 can flow into the drying device 40 through the drying duct.

[0053] See some examples. Figure 2 The garment processing equipment 100 also includes an air duct housing 50, which is disposed on the rear side of the tubular section 20 and connected to the tubular section 20. Please refer to [link to relevant documentation]. Figure 5 A guiding drying air duct 90 is formed between the air duct shell 50 and the cylindrical part 20. The guiding drying air duct 90 can be understood as a section of the aforementioned drying air duct.

[0054] Regarding the formation of a flow-guiding drying air duct 90 between the air duct housing 50 and the cylindrical part 20, please refer to some examples. Figure 3 A cavity 58 is formed inside the duct housing 50, and an opening 59 is provided on the side of the duct housing 50 that connects to the cylindrical part 20. Please refer to [link / reference]. Figure 3 The diagram illustrates the opening 59 of the air duct housing 50. The opening 59 extends along the length of the air duct housing 50 and communicates with the cavity 58. One end of the air duct housing 50 with the opening 59 is connected to the cylindrical portion 20, forming a guiding drying air duct 90 between the air duct housing 50 and the cylindrical portion 20. (See also...) Figure 5 This illustrates the formation of the airflow guiding and drying duct 90.

[0055] It should be noted that the example above describes the formation of a flow-guiding drying air duct 90 between the air duct housing 50 and the cylindrical part 20. In other examples, the air duct housing 50 may also be cylindrical, with the flow-guiding drying air duct 90 formed inside the air duct housing 50. The following description mainly uses the formation of a flow-guiding drying air duct 90 between the air duct housing 50 and the cylindrical part 20 as an example to further describe various embodiments.

[0056] Please see Figure 3 The diagram illustrates the filter device 60, which is typically installed inside the airflow drying duct 90. When the clothing processing equipment 100 dries the clothes, the air inside the drum section 20 flows into the airflow drying duct 90 and is filtered by the filter device 60 before flowing into the drying device 40. The filter device 60 can intercept impurities such as lint and fibers generated during the clothes drying process, ensuring the normal operation of the equipment, improving drying efficiency, and reducing safety risks.

[0057] See some examples. Figure 3 The filter device 60 can be installed on the air duct housing 50, for example, the filter device 60 can be detachably connected to the air duct housing 50.

[0058] Please see Figure 3 The clothing processing device 100 provided in this application embodiment also includes a spray structure 70, which is connected to the tubular part 20 and is disposed above the filter device 60.

[0059] See some examples. Figure 3 A connecting joint 51 is formed on the air duct housing 50, and the interior of the connecting joint 51 is connected to the interior of the spray structure 70. The clothing processing equipment 100 also includes a first water inlet pipe, and the connecting joint 51 is connected to the first water inlet pipe; or, in other examples, the spray structure 70 may be directly connected to the first water inlet pipe.

[0060] It should be noted that the clean water entering the spray structure 70 through the first water inlet pipe can rinse the filter screen device 60 and the guide drying air duct 90 through the spray structure 70. The rinsed water can flow into the cylindrical part 20. The cylindrical part 20 is connected to the drain pipe, and a drain pump is installed on the drain pipe. When the drain pump is in working condition, the water in the cylindrical part 20 can be discharged out of the cylindrical part 20 through the drain pipe.

[0061] In some examples, the garment processing device 100 also includes a water inlet valve, a second water inlet pipe, a third water inlet pipe, and a fourth water inlet pipe. The water inlet valve is fixed on the inner side of the outer casing 10. The first, second, third, and fourth water inlet pipes are all connected to the water inlet valve. The second water inlet pipe is connected to the condenser in the drying device 40 to provide condensation water to the condenser. The third and fourth water inlet pipes are both connected to the automatic cleaning liquid dispensing device of the garment processing device 100.

[0062] Please see Figure 3 The spray structure 70 includes a spray head 71, which is located within the guide drying air duct 90. The spray head 71 has water outlet holes 711. For details, please refer to [link to relevant documentation]. Figure 3 The outer surface of the spray head 71 includes a main area surface 715 and a filter screen facing surface 712. The filter screen facing surface 712 faces the filter screen device 60 and is provided with a water outlet hole 711. The main area surface 715 faces the duct wall of the guide drying air duct 90 and is provided with a water outlet hole 711.

[0063] In this embodiment, by setting the spray head 71 to face the filter screen facing surface 712 of the filter screen device 60 and providing water outlet holes 711, the water discharged from the water outlet holes 711 on the filter screen facing surface 712 can directly rinse the filter screen device 60, thereby improving the cleaning effect on the filter screen device 60. By setting the water outlet holes 711 to face the main area surface 715 of the guide drying air duct 90, the channel wall of the guide drying air duct 90 can also be cleaned to minimize the lint residue in the guide drying air duct 90 and to avoid the occurrence of odors caused by lint residue in the filter screen device 60 and the guide drying air duct 90.

[0064] In some embodiments, see Figure 4 The main area surface 715 includes a cylinder facing surface 713 facing the cylinder part 20 and a housing facing surface 714 facing the air duct housing 50, and a water outlet hole 711 is provided on at least one of the cylinder facing surface 713 and the housing facing surface 714.

[0065] Regarding the provision of a water outlet 711 on at least one of the cylinder facing surface 713 and the shell facing surface 714, it can be understood that, among the cylinder facing surface 713 and the shell facing surface 714, a water outlet 711 may be provided only on the cylinder facing surface 713, or a water outlet 711 may be provided only on the shell facing surface 714, or a water outlet 711 may be provided on both the cylinder facing surface 713 and the shell facing surface 714.

[0066] When a water outlet 711 is provided on the cylindrical facing surface 713, the water discharged from the water outlet 711 on the cylindrical facing surface 713 directly washes the side surface of the cylindrical part 20 because the cylindrical facing surface 713 faces the cylindrical part 20; when a water outlet 711 is provided on the shell facing surface 714, the water discharged from the water outlet 711 on the shell facing surface 714 directly washes the inner side surface of the air duct shell 50 because the shell facing surface 714 faces the air duct shell 50.

[0067] In this embodiment, by providing a water outlet 711 on at least one of the cylinder facing surface 713 of the spray head 71 facing the cylinder part 20 and the housing facing surface 714 of the air duct housing 50, the channel wall of the air duct 90 is cleaned to minimize the lint residue in the air duct 90 and to avoid odors caused by the filter device 60 and the lint residue in the air duct 90.

[0068] In some embodiments, the filter facing surface 712 can be set to a plane or a curved surface. For example, when the filter facing surface 712 is a curved surface, it can be set to an arc surface or a wavy surface.
