[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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 57 is formed inside the duct housing 50, and an opening 58 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 shows the opening 58 of the air duct housing 50. The opening 58 extends along the length of the air duct housing 50 and is connected to the cavity 57. The end of the air duct housing 50 with the opening 58 is connected to the cylindrical part 20 so that a guiding drying air duct 90 is formed between the air duct housing 50 and the cylindrical part 20.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Please see Figure 4 The spray structure 70 provided in this application embodiment includes a mounting part 72 and a spray head 71, with the spray head 71 connected to the mounting part 72.

[0065] The mounting part 72 is installed on the duct wall of the airflow drying duct 90. Please refer to [link / reference]. Figure 4 The diagram shows that the mounting part 72 is mounted on the air duct housing 50. The mounting part 72 is used to form a first water outlet 120 and the first water outlet 120 faces the filter screen device 60. Water sprayed from the first water outlet 120 can be sprayed onto the filter screen device 60.

[0066] Regarding the mounting portion 72 for forming the first water outlet 120, in some examples, the first water outlet 120 may be formed between the mounting portion 72 and the air duct housing 50, that is, the first water outlet 120 may be formed together by the mounting portion 72 and the air duct housing 50; or in other examples, the first water outlet 120 may be formed on the mounting portion 72, that is, the first water outlet 120 may be independently provided on the mounting portion 72.

[0067] Please see Figure 4 The nozzle 71 is connected to the mounting part 72. The nozzle 71 is provided with a second water outlet 711 and there is at least a second water outlet 711 facing the wall of the air duct.

[0068] Regarding the existence of at least one second water outlet 711 facing the duct wall, it can be understood that the second water outlet 711 on the spray head 71 can be configured to face only the duct wall of the guide flow drying duct 90, or, some of the second water outlets 711 on the spray head 71 can be configured to face the duct wall of the guide flow drying duct 90, while the other second water outlets 711 on the spray head 71 face the filter screen device 60.

[0069] In this embodiment, by providing a first water outlet 120 on the mounting part 72 and having the first water outlet 120 facing the filter device 60, the water sprayed from the first water outlet 120 can directly rinse the filter device 60, thereby improving the cleaning effect on the filter device 60. By providing a second water outlet 711 on the spray head 71 and having the second water outlet 711 facing at least the duct wall of the guide drying air duct 90, the channel wall of the guide drying air duct 90 is also cleaned, thereby minimizing the amount of lint residue in the guide drying air duct 90. In this embodiment, the occurrence of odors caused by lint residue in the filter device 60 and the guide drying air duct 90 can be avoided as much as possible.

[0070] In some embodiments, see Figure 4 The nozzle 71 includes a first region surface 712 and a second region surface 713. The first region surface 712 and the second region surface 713 face the inner side of the cylindrical part and the air duct housing 50, respectively. A second water outlet hole 711 is provided on at least one of the first region surface 712 and the second region surface 713.

[0071] Regarding the provision of a second water outlet 711 on at least one of the first region surface 712 and the second region surface 713, it can be understood that, in the first region surface 712 and the second region surface 713, the second water outlet 711 can be provided only on the first region surface 712, or the second water outlet 711 can be provided only on the second region surface 713, or the second water outlet 711 can be provided on both the first region surface 712 and the second region surface 713.

[0072] When a second water outlet 711 is provided on the first area surface 712, since the first area surface 712 faces the cylindrical part, the water discharged from the second water outlet 711 on the first area surface 712 directly washes the side of the cylindrical part; when a second water outlet 711 is provided on the second area surface 713, since the second area surface 713 faces the air duct housing 50, the water discharged from the second water outlet 711 on the second area surface 713 directly washes the inner side of the air duct housing 50.

[0073] In this embodiment, a second water outlet 711 is provided on at least one of the first area surface 712 facing the cylindrical part and the second area surface 713 facing the air duct housing 50, so as to clean the channel wall of the air duct 90.

[0074] In some embodiments, see Figure 4 The spray head 71 also includes a third region surface 714, which faces the filter screen device 60 and has a second water outlet 711. Please refer to [link to relevant documentation]. Figure 4The spray head 71 is positioned above the filter device 60, and the bottom surface of the spray head 71 is the third region surface 714.

[0075] In this embodiment, by providing a second water outlet 711 on the third region surface 714, since the third region surface 714 faces the filter screen device 60, the water sprayed from the second water outlet 711 on the third region surface 714 can directly rinse the filter screen device 60, thereby improving the cleaning effect on the filter screen device 60.

[0076] It should be noted that since the first water outlet 120 is provided on the mounting part 72 and the first water outlet 120 faces the filter screen device 60, in other embodiments, it is not necessary to provide the second water outlet 711 on the third area surface 714.

[0077] In some embodiments, the first region surface 712 can be set as a plane or a curved surface. For example, when the first region surface 712 is a curved surface, it can be set as an arc surface or a wavy surface.

[0078] In some embodiments, there are multiple second water outlet holes 711 on the first region surface 712, and the second water outlet holes 711 on the first region surface 712 are evenly distributed on the first region surface 712. For example, three second water outlet holes 711 may be provided on the first region surface 712, and the three second water outlet holes 711 may be arranged along...

[0081] In some embodiments, see Figure 4 The second area surface 713 includes a first side surface 7131, a second side surface 7132 and a third side surface 7133. The first side surface 7131, the second side surface 7132 and the third side surface 7133 are respectively facing the sides of the air duct housing 50 in different directions. At least one of the first side surface 7131, the second side surface 7132 and the third side surface 7133 is provided with a second water outlet 711.

[0082] Please see Figure 3Typically, the inner surface of the duct housing 50 includes an upper inner surface 52, a lower inner surface 53, a left inner surface 54, a right inner surface 55, and a rear inner surface 56. The upper inner surface 52 is positioned above the lower inner surface 53. The left inner surface 54 and the right inner surface 55 are positioned opposite each other, with their upper and lower ends connected to the upper inner surface 52 and the lower inner surface 53, respectively. The rear inner surface 56 faces the cylindrical portion 20 and connects to the upper inner surface 52, the lower inner surface 53, the left inner surface 54, and the right inner surface 55. The upper inner surface 52, the lower inner surface 53, the left inner surface 54, the right inner surface 55, and the rear inner surface 56 are located in different directions on the duct housing 50. In this embodiment, the first side 7131, the second side 7132, and the third side 7133 may be positioned facing the upper inner surface 52, the right inner surface 55, and the left inner surface 54, respectively.

Figure 4 This shows that the first side 7131 faces the upper inner side 52, the second side 7132 faces the left inner side 54, and the third side 7133 faces the right inner side 55.

[0083] The second water outlet 711 is provided on at least one of the first side 7131, the second side 7132, and the third side 7133. That is, the second water outlet 711 can be provided on one of the first side 7131, the second side 7132, and the third side 7133, or the second water outlet 711 can be provided on two of the first side 7131, the second side 7132, and the third side 7133, or the second water outlet 711 can be provided on all of the first side 7131, the second side 7132, and the third side 7133.

[0084] In some examples, the first side 7131 can be set to a plane or a curved surface, the second side 7132 to a plane or a curved surface, and the second side 7132 to a plane or a curved surface.

[0085] In some embodiments, there are multiple second water outlet holes 711 on the first side surface 7131, and the second water outlet holes 711 are evenly distributed on the first side surface 7131.

[0100] In some embodiments, the spray head 71 is integrally formed on the mounting portion 72.

[0101] In this embodiment, by integrally molding the spray head 71 onto the mounting portion 72, the number of parts can be reduced.

[0102] The above embodiment describes the spray head 71 being integrally formed on the mounting part 72. In other embodiments, the spray head 71 may also be connected to the mounting part 72 by screws or bolts.

[0103] In some embodiments, see Figure 7A mounting surface 561 for mounting the mounting part 72 is formed on the duct housing 50. Please refer to [link / reference]. Figure 8 A flow channel 110 is formed between the mounting part 72 and the mounting surface 561, and the interior of the spray head 71 is connected to the flow channel 110.

[0104] See some examples. Figure 6 The mounting part 72 is mounted on the rear inner side 56 of the air duct housing 50, that is, a portion of the rear inner side 56 forms the mounting surface 561.

[0105] See some examples. Figure 7 A connecting joint 51 is formed on the top of the duct housing 50, see [link / reference]. Figure 11 The two ends of the connector 51 are the inlet 511 and the outlet 512, respectively. The outlet 512 is formed inside the air duct housing 50, and the flow channel 110 is connected to the outlet 512.

[0106] See some examples. Figure 10 The mounting portion 72 is plate-shaped and includes a first plate surface 729 and a second plate surface 7210 disposed opposite each other along the thickness direction. The spray head 71 is disposed on the second plate surface 7210. The first plate surface 729 is used to form a flow channel 110 between itself and the mounting surface 561. Please refer to [link to previous section]. Figure 10 The mounting part 72 is provided with a connecting hole 723, which connects the first plate surface 729 and the second plate surface 7210. The side of the nozzle 71 facing away from the first area surface 712 is an open end. The flow channel 110 is connected to the interior of the nozzle 71 through the connecting hole 723 and the open end of the nozzle 71.

[0107] In this embodiment, a flow channel 110 is formed between the mounting part 72 and the mounting surface 561 to make full use of the air duct housing 50 to guide the flow, which helps to simplify the structure of the mounting part 72.

[0108] It should be noted that, in the above embodiment, a flow channel 110 is formed between the mounting part 72 and the mounting surface 561. In other embodiments, the flow channel 110 may be formed independently on the mounting part 72, instead of being formed by the mounting part 72 and the mounting surface 561.

[0109] In some embodiments, see Figure 8 A first water outlet 120 can be formed between the mounting part 72 and the mounting surface 561, that is, the first water outlet 120 is formed by the first plate surface 729 of the mounting part 72 and the mounting surface 561 of the air duct housing 50 together.

[0110] In this embodiment, by setting a first water outlet 120 between the mounting part 72 and the mounting surface 561, the structure of the mounting part 72 is simplified.

[0111] It is worth noting that the above embodiment describes the formation of a first water outlet 120 between the mounting part 72 and the mounting surface 561. In other embodiments, the first water outlet 120 may also be formed on the mounting part 72, that is, the first water outlet 120 is independently provided on the mounting part 72.

[0112] In some embodiments, see Figure 7 and Figure 9 The mounting section 72 includes a first plate segment 721 and a second plate segment 722. The second plate segment 722 is disposed at one end of the first plate segment 721 and the two are connected. A first water outlet 120 is formed between the second plate segment 722 and the mounting surface 561. Please refer to [link to previous section]. Figure 9 From the end connected to the first plate segment 721 to the end away from the first plate segment 721, the second plate segment 722 is inclined in the direction away from the mounting surface 561.

[0113] Please see Figure 7 The mounting surface 561 includes an upper mounting surface region 5611 and a lower mounting surface region 5612. The upper mounting surface region 5611 is located above the lower mounting surface region 5612 and the two are connected. The lower mounting surface region 5612 is inclined towards the mounting part 72 along the side connected to the upper mounting surface region 5611 to the side away from the upper mounting surface region 5611. The second plate segment 722 is directly opposite the lower mounting surface region 5612.

[0114] Please see Figure 9 The two sides of the second plate segment 722 along the thickness direction are the inner side 7221 and the outer side 7222 of the second plate segment, respectively. The inner side 7221 of the second plate segment is close to the mounting surface 561. From the end connected to the first plate segment 721 to the end away from the first plate segment 721, the inner side 7221 of the second plate segment is inclined in the direction away from the mounting surface 561.

[0115] See some examples. Figure 9 The outer surface 7222 of the second plate segment includes an upper region surface 72221 and a lower region surface 72222. The upper region surface 72221 is closer to the first plate segment 721 relative to the lower region surface 72222. From the end connected to the first plate segment 721 to the end away from the first plate segment 721, the upper region surface 72221 is inclined in a direction away from the inner surface 7221 of the second plate segment, and the lower region surface 72222 is inclined in a direction closer to the inner surface 7221 of the second plate segment.

[0116] See some examples. Figure 9The upper region surface 72221 and the lower region surface 72222 are connected by a circular arc transition.

[0117] In this embodiment, the second plate segment 722 is tilted in the direction away from the mounting surface 561 so that the first water outlet 120 faces the filter screen device 60, which facilitates the water sprayed from the first water outlet 120 to directly wash the filter screen device 60.

[0118] In some embodiments, see Figure 10 The second plate segment 722 has several water guide grooves 724 on the side facing the mounting surface 561, with one end of each groove extending to the side of the second plate segment 722 opposite to the first plate segment 721. (See also...) Figure 8 A flow channel 110 is formed between the first plate segment 721 and the mounting surface 561, and the water guide groove 724 cooperates with the mounting surface 561 to form the first water outlet 120.

[0119] Please see Figure 10 Multiple water guide channels 724 are along the length direction of the second plate segment 722 (i.e. Figure 10 The water guide trough 724 is set at intervals along the X-axis direction and extends along the width direction of the second plate segment 722.

[0120] In this embodiment of the application, a plurality of water guide grooves 724 are provided on the side of the second plate segment 722 facing the mounting surface 561, so that the water guide grooves 724 cooperate with the mounting surface 561 to form the first water outlet 120.

[0121] In some embodiments, see Figure 10 The mounting part 72 is provided with a sealing groove 725 on the side facing the mounting surface 561. The sealing groove 725 is used to install the sealing element 130 of the sealing mounting part 72 and the mounting surface 561.

[0122] See some examples. Figure 11 A first sealing protrusion 510 and a second sealing protrusion 520 are formed on the inner side of the air duct housing 50. The section of the connecting joint 51 located inside the air duct housing 50 is the inner section 513 of the joint. The first sealing protrusion 510 and the second sealing protrusion 520 are arranged opposite each other on both sides of the inner section 513 of the joint. One end of the first sealing protrusion 510 and the second sealing protrusion 520 are connected to the inner section 513 of the joint. The end of the first sealing protrusion 510 away from the inner section 513 of the joint extends to the area 5612 below the mounting surface. The end of the second sealing protrusion 520 away from the inner section 513 of the joint extends to the area 5612 below the mounting surface. The sealing element 130 is disposed on the first sealing protrusion 510, the inner section 513 of the joint and the second sealing protrusion 520, that is, the sealing element 130 is pressed between the sealing groove 725 and the first sealing protrusion 510, the inner section 513 of the joint and the second sealing protrusion 520.

[0123] See some examples. Figure 10 An avoidance groove 727 is formed on the mounting part 72, which is recessed to the side away from the inner section 513 of the connector.

[0124] In this embodiment, a sealing groove 725 is provided on the side of the mounting part 72 facing the mounting surface 561 to facilitate the sealing of the mounting part 72 and the mounting surface 561.

[0125] In some embodiments, see Figure 11 Multiple connecting posts 59 are formed on the inner surface of the air duct housing 50. Please refer to [link / reference]. Figure 9 and Figure 10 The mounting part 72 is provided with mounting holes 726. A connector 80 passes through the mounting holes 726 and is inserted into the corresponding connector 59 to mount the mounting part 72 onto the air duct housing 50.

[0126] See some examples. Figure 11 The first sealing protrusion 510 has one or more connecting posts 59 on the side opposite to the second sealing protrusion 520; the second sealing protrusion 520 has one or more connecting posts 59 on the side opposite to the first sealing protrusion 510.

[0127] In some examples, the first sealing protrusion 510 is provided with two connecting posts 59 on the side opposite to the second sealing protrusion 520, and the two connecting posts 59 are spaced apart along the length direction of the first sealing protrusion 510; the second sealing protrusion 520 is provided with two connecting posts 59 on the side opposite to the first sealing protrusion 510, and the two connecting posts 59 are spaced apart along the length direction of the second sealing protrusion 520.

[0128] In some examples, the height of the connecting post 59 protruding from the inner side of the duct housing 50 may be greater than the height of the first sealing protrusion 510 and the second sealing protrusion 520 protruding from the inner side of the duct housing 50.

[0129] See some examples. Figure 10 The first plate 729 of the mounting part 72 is provided with positioning grooves 728. The number of positioning grooves 728 is the same as the number of connecting posts 59. Mounting holes 726 are opened in the corresponding positioning grooves 728. One end of the connecting post 59 is inserted into the corresponding positioning groove 728.

[0130] In this embodiment, multiple connecting posts 59 are formed on the inner side of the duct housing 50 and mounting holes 726 are provided on the mounting part 72 to facilitate the connection of the connector 80 to the mounting part 72 and the duct housing 50.
