[0047] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] In the description of this utility model, it should be understood that the terms "thickness", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In the description of this utility model, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "first feature above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "first feature above", "above" and "over" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0050] The following description, with reference to the accompanying drawings, describes a garment processing device 1000 and an air duct system 100 according to embodiments of the present invention.

[0051] Reference Figures 1-13 As shown, the garment processing device 1000 according to an embodiment of the present invention includes an air duct system 100, and the air duct system 100 according to an embodiment of the present invention may include an air duct component 11.

[0052] Specifically, the air duct component 11 defines an air duct cavity 101, which has an inlet 1111. The inlet 1111 of the air duct cavity 101 allows airflow to enter the air duct cavity 101, and the air duct cavity 101 has an outlet for allowing airflow in the air duct cavity 101 to exit the air duct cavity 101, thereby achieving airflow circulation in the garment handling equipment 1000.

[0053] For example, in some embodiments, such as Figures 1-5As shown, the garment processing device 1000 also includes a garment processing cylinder assembly 200. The inlet 1111 and outlet of the air duct cavity 101 are both connected to the garment processing cylinder assembly 200, so that the airflow in the garment processing cylinder assembly 200 can enter the air duct cavity 101 through the inlet 1111, and the airflow in the air duct cavity 101 can enter the garment processing cylinder assembly 200 through the outlet of the air duct cavity 101, thereby realizing the circulation of airflow between the garment processing cylinder assembly 200 and the air duct cavity 101.

[0054] The air duct system 100 also includes a filter element 20, which is located at the inlet 1111 of the air duct cavity 101. The filter element 20 is used to filter impurities such as lint and hair adhering to the airflow. Specifically, during the garment processing process of the garment processing equipment 1000, lint and hair on the garments will enter the air duct cavity 101 with the circulating airflow. Lint and hair easily adhere to the working components (such as the evaporator and condenser) in the air duct cavity 101, resulting in low efficiency of the air duct system 100. Lint and hair are also easily and repeatedly adhered to the garments with the circulating airflow, resulting in low cleanliness of the processed garments. By filtering the airflow through the filter element 20 at the inlet 1111, the lint and hair adhering to the airflow can be filtered, reducing the impurity content in the airflow entering the air duct cavity 101 and in the circulating airflow, thereby improving the efficiency of the air duct system 100 and making the garments cleaner.

[0055] However, when airflow is filtered by filter element 20, impurities such as lint attached to the airflow will accumulate on filter element 20, which will reduce the filtration efficiency of filter element 20. Therefore, filter element 20 needs to be cleaned to remove the impurities accumulated on filter element 20, thereby improving the filtration efficiency of filter element 20.

[0056] In some related technologies, the air duct system needs to be disassembled to expose the filter to the outside environment, and then the filter needs to be removed from the air duct system before it can be cleaned. This process is complicated, time-consuming, and has low cleaning efficiency.

[0057] In this application, the air duct system 100 also includes a water spray assembly 12116, which is disposed on the air duct component 11 and has a water spray hole 1219 and a water spray chamber 1218. The water spray hole 1219 connects the water spray chamber 1218 and the air duct chamber 101, and sprays water toward the filter element 20.

[0058] By setting the water spray hole 1219, water from the water spray chamber 1218 can be sprayed into the air duct chamber 101 to clean the filter element 20. This allows impurities accumulated on the filter element 20 to leave the filter element 20 with the water, achieving self-cleaning of the filter element 20 and improving its filtration efficiency. Furthermore, the water spray hole 1219 is located above the filter element 20, spraying water towards it, allowing impurities to fall off the filter element 20 under gravity, resulting in a better cleaning effect.

[0059] The filter element 20 can be cleaned without removing it from the filter device 100. This is convenient, reduces the time required to disassemble the filter element 20, shortens the cleaning time, and improves cleaning efficiency.

[0060] In addition, compared with the prior art, which introduces a separate water spray component structure in the air duct component, the water spray assembly 12116 is set in the air duct component 11, and the water spray chamber 1218 is set in the air duct component 11. This solves the problems of opening holes in the air duct component 11 and installing the water spray component. In this application, the structure of the water spray assembly 12116 is simpler and the reliability is higher.

[0061] According to the embodiment of the present utility model, the air duct system 100 of the clothing treatment device 1000 can remove the impurities accumulated on the filter element 20 by spraying water toward the filter element 20 through the water spraying component 12116 located above the filter element 20, thereby realizing the self-cleaning of the filter element 20, improving the filtration efficiency of the filter element 20, and is easy to operate and has high cleaning efficiency.

[0062] Airflow enters the air duct cavity 101 after passing through the filter element 20 from the air inlet side. More impurities accumulated on the filter element 20 remain on its air inlet side surface. However, in some embodiments of this invention, such as... Figures 4-5 As shown, the water spray hole 1219 is located on the air outlet side of the filter element 20. Water can be sprayed from the air outlet side of the filter element 20 to the air inlet side of the filter element 20 through the water spray hole 1219, so that the impurities on the air inlet side of the filter element 20 are washed away by the water, thereby cleaning the impurities accumulated on the filter element 20.

[0063] Furthermore, the airflow within the duct component 11 passes through the filter element 20 from bottom to top, causing the water spray hole 1219 to be located on the air outlet side of the filter element 20, i.e., the upper side of the filter element 20. This allows the water spray hole 1219 to spray water downwards onto the filter element 20, enabling impurities accumulated on the filter element 20 to fall directly off with the water under gravity rather than remaining on the filter element 20, resulting in a better cleaning effect on the filter element 20.

[0064] Impurities falling from the filter element 20 can be handled in various ways. For example, in some embodiments, the impurities can be allowed to fall downwards into the outer tub of the clothing treatment drum assembly 200 and be discharged with the water. In other embodiments, a filter bag can be installed below the filter element 20 to collect the impurities for unified processing.

[0065] In some embodiments of this utility model, such as Figure 2 and Figures 4-5 As shown, the air duct cavity 101 includes a first chamber 1011 and a second chamber 1012 arranged and connected in a first direction. In the airflow direction, the first chamber 1011 is located between the inlet 1111 and the second chamber 1012. The first direction refers to the arrangement direction of the first chamber 1011 and the second chamber 1012. For example, in some specific embodiments, such as... Figure 5 As shown, the first direction is the front-to-back direction, and the first chamber 1011 and the second chamber 1012 are arranged along the front-to-back direction.

[0066] The first direction is set at an angle (e.g., acute, right, or obtuse) to the vertical direction, that is, the first chamber 1011 and the second chamber 1012 are not arranged in the vertical direction, but the airflow will flow from the first chamber 1011 to the second chamber 1012, which helps to shorten the flow path of the airflow in the vertical direction, thereby reducing the size of the air duct system 100 in the vertical direction and improving the spatial compactness of the air duct system 100.

[0067] In some embodiments, such as Figure 5 As shown, the water spray assembly 12116 participates in forming the first chamber 1011. The side surface of the water spray assembly 12116 facing the first chamber 1011 includes a guide surface 12115. The guide surface 12115 is located above the inlet 1111 and extends from bottom to top towards the second chamber 1012, so that the guide surface 12115 can guide the airflow in the first chamber 1011 to reduce wind resistance. Under the guidance of the guide surface 12115, the airflow can flow upward and more smoothly towards the second chamber 1012, which is beneficial to increase the airflow velocity in the duct cavity 101 and improve the working efficiency of the duct system 100.

[0068] For example, in some specific embodiments, such as Figure 5 As shown, the second chamber 1012 is located in front of the first chamber 1011. The lower surface of the water spray assembly 12116 is formed as a guide surface 12115. The guide surface 12115 is located above the inlet 1111 and extends from bottom to top and forward toward the second chamber 1012, so that the airflow of the first chamber 1011 flows more smoothly upward and forward toward the second chamber 1012 under the guidance of the guide surface 12115.

[0069] In some embodiments of this utility model, such as Figures 4-6As shown, the water spray assembly 12116 includes an inner cover 1213 and an outer cover 1215, with a water spray hole 1219 disposed on the inner cover 1213. The outer cover 1215 is disposed above the inner cover 1213 and defines a water spray cavity 1218 between the outer cover 1213 and the inner cover 1213.

[0070] The inner cover 1213 and the outer cover 1215 achieve at least double-layer sound insulation, resulting in better noise reduction. Specifically, as... Figure 5 As shown, there is a cavity, namely a water spray cavity 1218, between the inner cover 1213 and the outer cover 1215. The cavity forms an air sound insulation layer, which has a better noise reduction effect.

[0071] In some embodiments, such as Figures 4-6 As shown, the inner cover 1213 at least partially surrounds the filter element 20 and extends along the axial direction of the filter element 20, so that the water spray cavity 1218 defined by the inner cover 1213 and the outer cover 1215 is arranged around the filter element 20, which is conducive to the water sprayed from the water spray hole 1219 being sprayed onto the entire filter element 20, resulting in a better cleaning effect on the filter element 20.

[0072] In some embodiments of this utility model, such as Figure 6 As shown, there are multiple water spray holes 1219, which are arranged at intervals on the inner cover 1213. This allows the water sprayed onto the filter element 20 through the multiple water spray holes 1219 to form multiple water streams, so that the water is sprayed onto different parts of the filter element 20 more evenly, thus cleaning different parts of the filter element 20 and achieving a better cleaning effect on the filter element 20.

[0073] The penetration direction of the water spray hole 1219 can be flexibly set. For example, in some embodiments, the penetration direction of the water spray hole 1219 is perpendicular to the thickness direction of the inner cover 1213, which facilitates the control of the water spray direction of the water spray hole 1219 to control the angle of cleaning the filter element 20. In other embodiments, the penetration direction of the water spray hole 1219 extends vertically downward, which is beneficial to combine the water's own gravity to spray it vertically downward toward the filter element 20, thereby increasing the cleaning force on the filter element 20.

[0074] In some embodiments, such as Figure 5 and Figure 13 As shown, the inner cover 1213 has a guide arc surface 12115 on the side facing the filter element 20 to guide the airflow entering the air duct cavity 101 through the filter element 20 at the inlet 1111, reduce wind resistance, make the airflow flow more smoothly under the guidance of the guide arc surface 12115, and increase the airflow velocity to improve the working efficiency of the air duct system 100.

[0075] For example, in some embodiments, such as Figure 2 and Figures 4-5As shown, the air duct cavity 101 includes a first chamber 1011 and a second chamber 1012 arranged and connected in a first direction. The first chamber 1011 is located upstream of the second chamber 1012 in the airflow direction. The first direction refers to the arrangement direction of the first chamber 1011 and the second chamber 1012. For example, in some specific embodiments, such as... Figure 5 As shown, the first direction is the front-to-back direction, and the first chamber 1011 and the second chamber 1012 are arranged along the front-to-back direction.

[0076] The first direction is set at an angle (e.g., acute, right, or obtuse) to the vertical direction, that is, the first chamber 1011 and the second chamber 1012 are not arranged in the vertical direction, but the airflow will flow from the first chamber 1011 to the second chamber 1012, which helps to shorten the flow path of the airflow in the vertical direction, thereby reducing the size of the air duct system 100 in the vertical direction and improving the spatial compactness of the air duct system 100.

[0077] like Figure 5 As shown, the inner cover 1213 participates in forming the first chamber 1011. The side surface of the inner cover 1213 facing the first chamber 1011 includes a guide arc surface 12115. The guide arc surface 12115 is located above the inlet 1111 and extends from bottom to top towards the second chamber 1012, so that the guide arc surface 12115 can guide the airflow in the first chamber 1011 to reduce wind resistance. Under the guidance of the guide arc surface 12115, the airflow can flow more smoothly upward and towards the second chamber 1012, which is beneficial to increase the airflow velocity in the air duct cavity 101 and improve the working efficiency of the air duct system 100.

[0078] For example, in some specific embodiments, such as Figure 5 As shown, the second chamber 1012 is located in front of the first chamber 1011. The lower surface of the inner cover 1213 is formed as a guide arc surface 12115. The guide arc surface 12115 is located above the inlet 1111 and extends from bottom to top and forward toward the second chamber 1012, so that the airflow of the first chamber 1011 flows more smoothly upward and forward to the second chamber 1012 under the guidance of the guide arc surface 12115.

[0079] In some embodiments of this utility model, such as Figures 2-5 and Figure 7As shown, the outer cover 1215 has a water inlet connector 12110 for connecting to a water source on the side opposite to the inner cover 1213. The water inlet connector 12110 is connected to the spray chamber 1218. A certain amount of water is introduced into the spray chamber 1218 through the water inlet connector 12110, so that the water volume in the spray chamber 1218 is controllable. By controlling the water volume in the spray chamber 1218, the amount of water sprayed onto the filter element 20 can be controlled, thereby controlling the cleaning intensity of the filter element 20. Different cleaning intensities are considered as different levels, which facilitates multi-level cleaning of the filter element 20 and improves the cleaning effect.

[0080] In some embodiments of this utility model, the outer cover 1215 and the inner cover 1213 are integrally formed, making the outer cover 1215 and the inner cover 1213 more robust and durable in overall structure, for example, less prone to relative movement or even separation, and more practical.

[0081] In some embodiments of this utility model, such as Figures 5-7 As shown, the outer cover 1215 and the inner cover 1213 are connected together by welding, snap-fitting, or fasteners, so that the outer cover 1215 and the inner cover 1213 can be formed separately, which helps to reduce the manufacturing difficulty of the outer cover 1215 and the inner cover 1213 and facilitates their widespread use.

[0082] The fastener can be one or more of bolts, screws, rivets, etc. For example, in some embodiments where the fastener is a screw, not only can the outer cover 1215 and the inner cover 1213 be firmly connected, but the bolt is also easy to install and remove, which facilitates the subsequent disassembly and assembly of the outer cover 1215 and the inner cover 1213 for maintenance, replacement and other work.

[0083] In some embodiments of this utility model, such as Figures 5-6 As shown, one of the outer cover 1215 and the inner cover 1213 has a slot 12111 and the other has a plug part 12112 that mates with the slot 12111. The mate between the slot 12111 and the plug part 12112 can position the installation of the outer cover 1215 and the inner cover 1213, reducing the possibility of misalignment between the outer cover 1215 and the inner cover 1213, thereby reducing the risk of air leakage in the air duct cavity 101 and water leakage in the water spray cavity 1218, which helps to improve the working stability of the air duct system 100.

[0084] In some embodiments, such as Figure 5As shown, the outer cover 1215 has a first snap-fit ​​portion 12113, the inner cover 1213 has a second snap-fit ​​portion 12114, the duct base 111 has a first snap-fit ​​mating portion 1112 and a third snap-fit ​​portion 1113, and the connecting pipe 300 has a second snap-fit ​​mating portion 310 and a third snap-fit ​​mating portion 320. The outer cover 1215 and the duct base 111 are connected through the first snap-fit ​​portion 12113 and the first snap-fit ​​mating portion 1112, the inner cover 1213 and the connecting pipe 300 are connected through the second snap-fit ​​portion 12114 and the second snap-fit ​​mating portion 310, and the duct base 111 and the connecting pipe 300 are connected through the third snap-fit ​​portion 1113 and the third snap-fit ​​mating portion 320, making disassembly and assembly convenient.

[0085] In some embodiments of this utility model, such as Figures 4-5 and Figures 8-11 As shown, the air duct system 100 also includes a cleaning component 31, which is rotatably disposed at the filter element 20 to clean the filter element 20 during rotation. By continuously cleaning the filter element 20 through the rotating cleaning component 31, accumulated impurities on the filter element 20 can be agglomerated and peeled off from the surface of the filter element 20, achieving self-cleaning of the filter element 20 and improving its filtration efficiency. Furthermore, the filter element 20 can be cleaned without removing it from the air duct system 100, making operation convenient, reducing the time required for disassembling the filter element 20, and thus shortening cleaning time and improving cleaning efficiency. Combining the outer cover 1215 and the inner cover 1213 to clean the filter element 20 provides diverse self-cleaning methods, which helps to improve the cleaning effect of the filter element 20.

[0086] The air duct system 100 also includes a drive component 32, which is connected to the cleaning component 31 and is used to drive the cleaning component 31 to rotate. The drive component 32 can drive the cleaning component 31 to rotate by means of electric drive or mechanical drive, and the driving method is diverse.

[0087] For example, in some embodiments, the drive element 32 is a motor, and the output shaft of the motor is directly or indirectly connected to the cleaning element 31, so that the cleaning element 31 rotates synchronously with the output shaft 321. In other embodiments, the drive element 32 includes a portion connected to the cleaning element 31 and a handheld portion extending out of the air duct system 100, so that the user can drive the cleaning element 31 to rotate through the handheld portion.

[0088] In some embodiments of this utility model, such as Figures 4-5 and Figures 8-10 As shown, the filter element 20 has a circular structure, and the center of the filter element 20 is located on the rotation axis of the cleaning element 31. This allows the rotating cleaning element 31 to clean the filter element 20 more thoroughly, covering all areas from the center outwards, reducing cleaning dead spots and improving the cleaning effect on the filter element 20.

[0089] In particular, in some embodiments, such as Figure 7 As shown, in the direction perpendicular to the rotation axis of the cleaning component 31, the size of the cleaning component 31 is equal to the radius of the filter component 20, so that the rotating cleaning component 31 can clean all areas of the filter component 20 from the center to the outer periphery, reduce the missed brushing area, and achieve a better cleaning effect on the filter component 20.

[0090] In some embodiments, such as Figure 5 As shown, the cleaning component 31 and the driving component 32 are located on opposite sides of the filter element 20. This prevents lint and other impurities cleaned by the cleaning component 31 from falling onto the driving component 32 and clogging it. This also facilitates smoother rotation of the cleaning component 31, reducing the likelihood of jamming or even stuck, thus improving the reliability of the cleaning component 31 in cleaning the filter element 20. Furthermore, it allows for full utilization of the space on both sides of the filter element 20 along the arrangement direction of the cleaning component 31 and the driving component 32, resulting in a more compact arrangement of the filter element 20 and cleaning component 31 within the air duct system 100 and improving the utilization rate of the installation space within the air duct system 100.

[0091] Airflow enters the air duct cavity 101 after passing through the filter element 20 from the air inlet side. More impurities accumulated on the filter element 20 will remain on the air inlet side surface. However, in some embodiments of this invention, such as... Figure 5 As shown, the cleaning component 31 is located on the air inlet side of the filter element 20. The cleaning component 31 can clean the air inlet side surface of the filter element 20 to directly clean the impurities accumulated on the filter element 20, resulting in a better cleaning effect on the filter element 20.

[0092] After being filtered by the filter element 20, the airflow enters the air duct cavity 101 from the air outlet side of the filter element 20, resulting in a low impurity content in the airflow at the air outlet side of the filter element 20. The drive element 32 is located on the air outlet side of the filter element 20, which not only facilitates subsequent disassembly and replacement of the drive element 32, but also reduces the amount of impurities adhering to the airflow flowing through the drive element 32, lowers the risk of the drive element 32 being blocked by impurities, and helps protect the drive element 32.

[0093] In some embodiments, such as Figure 5 As shown, the cleaning component 31 is located on the lower side of the filter component 20, so that the impurities accumulated on the filter component 20 after the cleaning component 31 cleans the filter component 20 can fall directly and are not easy to stay on the filter component 20. In addition, the airflow flows upward through the filter component 20, so that the cleaning component 31 is located on the air inlet side of the filter component 20, which makes the cleaning effect of the filter component 20 better.

[0094] In some embodiments, such as Figure 5 and Figures 8-9As shown, the drive component 32 is connected to the cleaning component 31 via the connecting shaft 33, so that the drive component 32 and the cleaning component 31 are connected via the connecting shaft 33. The distance between the drive component 32 and the cleaning component 31 can be adjusted via the connecting shaft 33, so that the relative positions of the drive component 32 and the cleaning component 31 can be flexibly set.

[0095] The filter element 20 can be sleeved on the connecting shaft 33, and the connecting shaft 33 can limit the filter element 20, making it difficult for the filter element 20 to move relative to the connecting shaft 33 in the radial direction, thereby reducing the possibility of airflow entering the air duct cavity 101 from the edge of the filter element 20, and making the filter element 20 filter the airflow at the inlet 1111 better.

[0096] In some embodiments, such as Figures 9-10 As shown, the peripheral wall of the connecting shaft 33 has a limiting protrusion 331, and the filter element 20 is sleeved on the connecting shaft 33 and the filter element 20 is located between the limiting protrusion 331 and the cleaning element 31.

[0097] The filter element 20 can be limited along the axial direction of the connecting shaft 33 by the limiting protrusion 331 and the cleaning element 31, and the filter element 20 can be limited along the radial direction of the connecting shaft 33 by the filter element 20 being sleeved on the connecting shaft 33, thereby reducing the possibility of relative movement between the filter element 20 and the connecting shaft 33, so as to reduce the risk of airflow entering the air duct cavity 101 from the edge of the filter element 20, and making the filter element 20 have a better filtration effect on the airflow at the inlet 1111.

[0098] In some embodiments, such as Figure 5 and Figures 8-11 As shown, the cleaning component 31 includes a connecting part 311, which is sleeved on and connected to the connecting shaft 33 so that the cleaning component 31 is securely installed on the connecting shaft 33.

[0099] The connection between the connecting part 311 and the connecting shaft 33 can be one or a combination of screw connection, snap-fit, adhesive bonding, welding, etc.

[0100] For example, in some embodiments, the connecting part 311 has a special-shaped hole, one end of the connecting shaft 33 is engaged with the special-shaped hole, and the connecting part 311 and the connecting shaft 33 are tightly connected by inserting one end of the connecting shaft 33 into the special-shaped hole. Then, the connecting shaft 33 and the connecting part 311 are fixed by screws, so that the cleaning part 31 and the connecting shaft 33 are firmly connected.

[0101] The filter element 20 is located between the limiting protrusion 331 and the connecting portion 311 of the cleaning element 31, so that the filter element 20 is axially limited by the limiting protrusion 331 and the connecting portion 311, and the limiting effect of the filter element 20 is better.

[0102] In some examples, the cleaning component 31 includes a flexible brush portion 312 connected to the connecting portion 311. The flexible brush portion 312 abuts against the filter element 20. The deformation of the flexible brush portion 312 allows it to continuously abut against the filter element 20 during the rotation of the cleaning component 31, thereby continuously cleaning the filter element 20. This results in a better cleaning effect on the filter element 20, and the flexible brush portion 312 is deformable, making it less likely to damage the filter element 20.

[0103] The flexible brush part 312 can be a bristle brush, which is inexpensive and economical. The flexible brush part 312 can also be made of rubber, which can deform to clean the filter element 20 without shedding bristles, making it easy to use.

[0104] The flexible brush portion 312 can be a single unit or comprise multiple parts. For example, in some embodiments, such as... Figures 8-9 As shown, the flexible brush part 312 includes a flexible brush head 313 and a rigid limiting part 314. The flexible brush head 313 is inserted into the limiting part 314. The rigid limiting part 314 is not easily deformed. The limiting part 314 can limit the flexible brush head 313, so that the flexible brush head 313 is not easily deformed and cannot press the filter element 20. This is beneficial to ensure that the flexible brush head 313 always presses the filter element 20 during rotation, so as to achieve powerful cleaning of the filter element 20 and better cleaning effect.

[0105] In some embodiments of this utility model, such as Figures 1-5 As shown, the inlet 1111 and the outlet are located on the air duct component 11, with the inlet 1111 located at the bottom of the air duct component 11. This allows the airflow to flow upward from the bottom of the air duct component 11 into the air duct cavity 101. Impurities such as lint attached to the airflow are more likely to fall off under their own gravity and are less likely to enter the air duct cavity 101, which helps to improve the filtration effect of the filter element 20 at the inlet 1111 on the airflow.

[0106] like Figure 1 , Figure 5 and Figures 10-13 As shown, the inner cover 1213 and the outer cover 1215 are detachably disposed on the air duct component 11. The cleaning component 31 and the driving component 32 are installed on the inner cover 1213 and the outer cover 1215. After the cleaning component 31, the driving component 32, the inner cover 1213 and the outer cover 1215 are integrated into one unit, they can be detachably installed on the air duct component 11. This makes it easy to remove the inner cover 1213 and the outer cover 1215 from the air duct component 11 for cleaning, maintenance or replacement of the cleaning component 31 and the driving component 32.

[0107] In some embodiments where the filter element 20 is installed in the inner cover 1213 and the outer cover 1215, the filter element 20, the inner cover 1213, and the outer cover 1215 can be integrated into one unit and then detachably installed in the air duct component 11. This facilitates the removal of the inner cover 1213 and the outer cover 1215 from the air duct component 11 for manual cleaning or replacement of the filter element 20. For example, the filter element 20 can be removed from the inner cover 1213 and the outer cover 1215 for cleaning or replacement, or the filter element 20, the inner cover 1213, and the outer cover 1215 can be cleaned and replaced as a whole. The filter element 20 can be self-cleaned and manually cleaned, offering a variety of cleaning methods.

[0108] In some embodiments, the inner circumference of the inner cover 1213 is provided with an annular groove that matches the outer circumference of the filter element 20, so that the filter element 20 is firmly installed in the inner cover 1213 and is not easy to shake, resulting in better filtration effect.

[0109] In some embodiments, the inner cover 1213 and the outer cover 1215 can be made of plastic, alloy or other materials, and the filter element 20 can be made of metal or polyester, etc. The inner cover 1213, the outer cover 1215 and the filter element 20 can be integrally formed or separately formed, etc., which can be flexibly selected according to the needs.

[0110] In some embodiments, such as Figures 4-5 As shown, the wall of the air duct component 11 at the inlet 1111 is flush with the filter element 20, which enables the filter element 20 to intercept most of the impurities at the inlet 1111 and makes it less likely for the filter element 20 to occupy the space of the air duct cavity 101. This makes it easier to make full use of the space at the inlet 1111 to increase the space of the air duct cavity 101, so that the airflow is smoother after entering the air duct cavity 101 from the inlet 1111, and reduces the risk of impurities such as lint remaining on the bottom wall of the air duct cavity 101.

[0111] For example, in some specific embodiments, such as Figure 5 As shown, on the horizontal plane, the wall of the air duct component 11 at the inlet 1111 is flush with the filter element 20.

[0112] It is understandable that there is a certain error in the flushing between the wall of the air duct component 11 at the inlet 1111 and the filter element 20, so that the two are roughly flush, in order to reduce the manufacturing difficulty of the air duct system 100.

[0113] In some embodiments, such as Figure 6 As shown, the inner cover 1213 defines a mounting cavity 1211 for mounting the drive member 32. The cavity wall of the mounting cavity 1211 is provided with a through hole 1217 for the output shaft 321 of the drive member 32 to pass through, so that the output shaft 321 passes through the through hole 1217 and connects with the cleaning member 31, thereby driving the cleaning member 31 to rotate so that the cleaning member 31 cleans the filter element 20.

[0114] The mounting cavity 1211 can also be defined by the outer cover 1215, or it can be defined by the outer cover 1215 and the inner cover 1213 together. The defining structure of the mounting cavity 1211 is diverse.

[0115] In some embodiments, such as Figure 6 As shown, there are multiple water spray holes 1219, which are spaced apart on the outer periphery of the mounting cavity 1211 to rationally arrange the drive component 32 and the water spray holes 1219, reducing the risk of damage to the drive component 32 due to water ingress. Furthermore, spraying water onto the filter element 20 through the multiple water spray holes 1219 can clean the cleaning component 31 on the filter element 20, thus improving the cleaning effect of the cleaning component 31.

[0116] In some embodiments of this utility model, such as Figures 5-7 As shown, the outer cover 1215 has a clearance hole 1216, and the inner cover 1213 includes a mounting part 1214, which is inserted into the clearance hole 1216. The mounting part 1214 defines a mounting cavity 1211.

[0117] By inserting the mounting portion 1214 of the inner cover 1213 into the clearance hole 1216 of the outer cover 1215, it is only necessary to provide a through hole 1217 in the mounting cavity 1211 of the inner cover 1213 to connect the mounting cavity 1211 and the air duct cavity 101. It is not necessary to provide small through holes 1217 for the output shaft 321 to pass through in both the inner cover 1213 and the outer cover 1215, which helps to reduce the manufacturing difficulty of the inner cover 1213 and the outer cover 1215.

[0118] In some embodiments, such as Figures 5-7 and Figures 10-13 As shown, the mounting portion 1214 has an opening on the side away from the air duct cavity 101, which communicates with the mounting cavity 1211. The outer cover 1215 has a cover 122 on the side opposite to the inner cover 1213, which is used to open and close the clearance hole 1216 and the opening. The opening is opened by the cover 122 to install the drive component 32, and the opening is closed by the cover 122 to isolate the mounting cavity 1211 from the outside, which helps to protect the drive component 32 inside the mounting cavity 1211.

[0119] In some embodiments, such as Figure 1 and Figure 13 As shown, at least one of the inner cover 1213 and the outer cover 1215 is connected to the air duct component 11 by a plurality of fasteners, and the outer cover 1215 is disposed on the inner cover 1213, so that the inner cover 1213, the outer cover 1215 and the air duct component 11 are firmly connected, so that the inner cover 1213 and the outer cover 1215 are not easy to shake relative to the air duct component 11, thereby making the cleaning effect of the inner cover 1213 and the outer cover 1215 on the filter element 20 more stable.

[0120] In some embodiments, such as Figures 1-3 and Figures 12-13 As shown, the outer cover 1215 is provided with multiple mounting lugs 1212. The multiple mounting lugs 1212 are arranged circumferentially on the outer cover 1215. Each mounting lug 1212 is connected to the air duct component 11 by fasteners, so that multiple parts of the outer cover 1215 are connected to the air duct component 11 by fasteners at circumferential intervals, and the connection between the outer cover 1215 and the air duct component 11 is more secure.

[0121] In some embodiments of this utility model, such as Figures 1-6 and Figure 13 As shown, the air duct component 11 includes an air duct base 111 and an inlet 1111 is located on the air duct base 111, so that the inlet 1111 is located at the bottom of the air duct component 11, which makes it easier for impurities attached to the airflow entering the inlet 1111 to fall off under their own gravity and not easily enter the air duct cavity 101, thus improving the filtration effect of the airflow.

[0122] The air duct component 11 also includes an air duct cover plate 112, which is located on the top of the air duct base 111 and defines at least a portion of the air duct cavity 101 between the air duct cover plate 112 and the air duct base 111 to isolate the air duct cavity 101 from the outside, thereby protecting the relative airtightness of the air duct cavity 101.

[0123] In some embodiments, the duct cover 112 itself defines a mounting opening 1101, for example, by having an opening in the duct cover 112 to define the mounting opening 1101. In other embodiments, the mounting opening 1101 is defined between the duct cover 112 and the duct base 111, for example... Figure 1 and Figure 13 As shown, an installation port 1101 is defined on the upper side of the air duct base 111, which is not opposite to the air duct cover 112. The defining structure of the installation port 1101 is varied.

[0124] The outer cover 1215 is located at the mounting port 1101, which facilitates the connection with the outside world through the outer cover 1215 to allow water to be supplied to the water spray chamber 1218, and then water is sprayed onto the filter element 20 through the water spray hole 1219 to clean the filter element 20.

[0125] The inner cover 1213 is connected to the air duct base 111, the outer cover 1215 is connected to the air duct base 111, and the outer cover 1215 is connected to the air duct cover 112. The outer cover 1215 is located on the inner cover 1213, that is, the outer cover 1215 is connected to the inner cover 1213 or is an integral part, so that the inner cover 1213, the outer cover 1215, the air duct base 111 and the air duct cover 112 are firmly connected, which helps to improve the working stability of the air duct system 100.

[0126] The duct cover 112 can be a single piece, which improves the relative sealing between the entire duct cover 112 and the duct cavity 101 defined by the duct base 111. The duct cover 112 can also consist of multiple parts. These multiple parts can be formed into different shapes to match different parts of the duct base 111, which helps to make the connection between the duct base 111 and the duct cover 112 more secure. It also facilitates the maintenance or replacement of parts of the duct cover 112 rather than the entire duct cover 112, resulting in better economic efficiency.

[0127] For example, in some embodiments, such as Figures 1-4 and Figure 13 As shown, the duct cover 112 includes a first cover 1121 and a second cover 1122. The duct cavity 101 includes a first chamber 1011, a second chamber 1012 and a heat exchange cavity 1013. The first chamber 1011 is located behind the second chamber 1012, and the heat exchange cavity 1013 is located to the right of the first chamber 1011 and the second chamber 1012. The heat exchange cavity 1013 is provided with heat exchange components such as an evaporator and a condenser (not shown in the figure). The airflow flows through the first chamber 1011, the second chamber 1012 and the heat exchange cavity 1013 in sequence. The outer cover 1215 and the inner cover 1213 are used to cover the first chamber 1011, the first cover plate 1121 is used to cover the second chamber 1012, and the second cover plate 1122 is used to cover the heat exchange chamber 1013, so as to match the shapes of the first chamber 1011, the second chamber 1012, and the heat exchange chamber 1013, making the connection between the outer cover 1215 and the inner cover 1213 and the first chamber 1011, the first cover plate 1121 and the second chamber 1012, and the second cover plate 1122 and the heat exchange chamber 1013 more secure.

[0128] In some embodiments, such as Figure 5 As shown, the mounting port 1101 is located at the top of the air duct component 11, and the mounting port 1101 and the inlet 1111 are arranged opposite each other in the vertical direction. The cleaning component 31, the inner cover 1213 and the outer cover 1215 are integrated into one unit and are located at the mounting port 1101. The filter element 20 is located at the inlet 1111, so that the cleaning component 31 and the filter element 20 are arranged opposite each other in the vertical direction, which facilitates the cleaning component 31 to clean the filter element 20.

[0129] In some embodiments, such as Figure 3 and Figure 13 As shown, at least a portion of the outer cover 1215 is pressed onto the duct cover 112 and the two are connected by fasteners, so that the outer cover 1215 and the duct cover 112 are firmly connected and the airflow is not easy to flow out from the gap between the outer cover 1215 and the duct cover 112, which helps to ensure the relative sealing of the duct cavity 101.

[0130] For example, in some specific embodiments, such as Figure 3 and Figure 13As shown, a mounting lug 1212 of the outer cover 1215 is pressed onto the air duct cover 112. The mounting lug 1212 and the air duct cover 112 are connected by fasteners, so that the outer cover 1215 and the air duct cover 112 are firmly connected.

[0131] The clothing processing device 1000 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0132] like Figure 1 and Figures 3-4 As shown, the clothing processing device 1000 according to an embodiment of the present invention includes a clothing processing drum assembly 200 and an air duct system 100 according to an embodiment of the present invention. The air outlet of the clothing processing drum assembly 200 is connected to the air inlet 1111, and the air inlet of the clothing processing drum assembly 200 is connected to the air outlet, so as to realize the circulation of airflow between the clothing processing drum assembly 200 and the air duct cavity 101.

[0133] Since the air duct system 100 according to the present utility model embodiment has the above-mentioned beneficial technical effects, the clothing treatment device 1000 according to the present utility model embodiment can remove the impurities accumulated on the filter element 20 by spraying water toward the filter element 20 through the water spraying assembly 12116 located above the filter element 20, thereby realizing the self-cleaning of the filter element 20, improving the filtration efficiency of the filter element 20, and is easy to operate and has high cleaning efficiency.

[0134] The garment processing equipment 1000 can be used for operations such as drying clothes. For example, the garment processing equipment 1000 can be a dryer or a washer-dryer combo.

[0135] In some embodiments, the clothing processing device 1000 is a dryer. The working process and drying principle of the dryer are as follows: Dry hot airflow in the air duct cavity 101 enters the clothing processing drum assembly 200 through the outlet of the air duct cavity 101. The dry hot airflow flows over the surface of the wet clothing within the clothing processing drum assembly 200 to exchange heat and moisture with the wet clothing, absorbing moisture from the clothing and transforming the dry hot airflow into a humid airflow. The humid airflow in the clothing processing drum assembly 200 enters the air duct cavity 101 through the inlet 1111. The air duct system 100 includes heat exchange components such as an evaporator and a condenser. The humid airflow exchanges heat with the heat exchange components within the air duct cavity 101 to form a dry hot airflow. The dry hot airflow in the air duct cavity 101 enters the clothing processing drum assembly 200 through the outlet of the air duct cavity 101. The above process is repeated cyclically, causing the airflow to circulate and achieving the drying function. The drying airflow includes airflows in different states circulating between the clothing processing drum assembly 200 and the air duct cavity 101, such as dry hot airflow and humid airflow.

[0136] The garment handling drum assembly 200 may include a double-drum structure, such as an inner drum and an outer drum, wherein the outer drum is stationary and the inner drum rotates relative to the outer drum to agitate the garments inside the inner drum. The garment handling drum assembly 200 may also include a single-drum structure, such as a stationary single drum with an agitator suspended above it to agitate the garments inside the single drum. The type of garment handling drum assembly 200 can be flexibly selected.

[0137] In some embodiments of this utility model, such as Figure 1 and Figures 4-5 As shown, the garment processing device 1000 also includes a connecting pipe 300, which connects the air outlet and the inlet 1111. The cleaning component 31 extends into the connecting pipe 300. The connecting pipe 300 connects the inlet 1111 of the ventilation duct cavity 101 and the air outlet of the garment processing drum assembly 200, allowing the airflow in the garment processing drum assembly 200 to flow through the connecting pipe 300 into the ventilation duct cavity 101, which helps to ensure the relative sealing of the ventilation duct cavity 101 and the inner cavity of the garment processing drum assembly 200.

[0138] The cleaning component 31 extends into the connecting pipe 300 to utilize the space within the connecting pipe 300 for installation of the cleaning component 31, without occupying the space within the air duct cavity 101 and the clothing handling cylinder assembly 200, thus improving the space compactness of the clothing handling equipment 1000.

[0139] In some embodiments, such as Figures 4-5 As shown, one end of the connecting pipe 300 has a connecting flange (e.g. Figure 5 The third snap-fit ​​part 320 in the middle, the connecting flange extends into the air duct cavity 101 through the inlet 1111, the mounting base 12 is located above the connecting flange, so that the connecting flange is clamped between the mounting base 12 and the structure that defines the inlet 1111 in the air duct component 11, so that the connecting pipe 300 is more firmly installed between the mounting base 12 and the air duct component 11, and gaps are less likely to occur between the connecting pipe 300 and the mounting base 12, and between the connecting pipe 300 and the air duct component 11, so that the airflow in the clothing handling drum assembly 200 can smoothly enter the air duct cavity 101 through the connecting pipe 300, reduce the risk of airflow leakage, and improve the working stability of the clothing handling equipment 100.

[0140] For example, in some specific embodiments, such as Figure 5 As shown, the third snap-fit ​​part 320 of the connecting pipe 300 is sandwiched between the second snap-fit ​​part 12114 of the mounting base 12 and the air duct base 111 of the air duct component 11.

[0141] The following describes in detail, with reference to the accompanying drawings, a specific embodiment of the air duct system 100 and a clothing processing device 1000 according to the present invention. It should be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0142] like Figures 1-13 As shown, a clothing processing device 1000 according to a specific embodiment of the present utility model includes an air duct system 100, a clothing processing cylinder assembly 200 and a connecting pipe 300. The air duct system 100 includes an air duct assembly 10, a filter element 20, a water spray assembly 12116 and a cleaning assembly 30. The air duct assembly 10 includes an air duct component 11 and a mounting base 12.

[0143] The air duct component 11 defines an air duct cavity 101, which has an inlet 1111 and an outlet. The inlet 1111 is connected to the air outlet of the clothes handling drum assembly 200 through a connecting pipe 300, and the outlet is connected to the air inlet of the clothes handling drum assembly 200, so that the airflow circulates between the clothes handling drum assembly 200 and the air duct cavity 101.

[0144] The air duct cavity 101 includes a first chamber 1011, a second chamber 1012, and a heat exchange cavity 1013. The first chamber 1011 is located behind the second chamber 1012, and the heat exchange cavity 1013 is located to the right of the first chamber 1011 and the second chamber 1012. The heat exchange cavity 1013 is provided with heat exchange components such as an evaporator and a condenser. The airflow flows through the first chamber 1011, the second chamber 1012, and the heat exchange cavity 1013 in sequence.

[0145] The air duct component 11 includes a connected air duct base 111 and an air duct cover 112. The air duct cover 112 is located on top of the air duct base 111.
