Detailed Implementation

[0025] 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.

[0026] The following is for reference. Figures 1-22This invention describes a garment processing device 100 according to an embodiment of the present invention. The garment processing device 100 can be a washing machine or a washer-dryer combo, such as a wall-mounted washing machine or a wall-mounted washer-dryer combo.

[0027] Reference Figures 1-5 According to an embodiment of the present utility model, the clothing processing device 100 includes an outer cylinder assembly 10 and an inner cylinder (not shown in the figure). The outer cylinder assembly 10 includes an outer cylinder 11 and an anti-overflow device 16. The outer cylinder 11 has an installation port 115. The anti-overflow device 16 is disposed at the installation port 115 and has a through hole 1621. The through hole 1621 connects the inner and outer spaces of the outer cylinder 11. The inner cylinder is rotatably disposed inside the outer cylinder 11.

[0028] Furthermore, the anti-overflow device 16 includes a sealing member 161, which is used to open and close the through hole 1621. When the sealing member 161 is in the open state of the through hole 1621, the through hole 1621 connects the inner and outer spaces of the outer cylinder 11. When the sealing member 161 is in the closed state of the through hole 1621, the sealing member 161 blocks the inner and outer spaces of the outer cylinder 11.

[0029] For example, in the initial or normal state, the sealing member 161 opens the through hole 1621 of the garment handling device 100, connecting the internal space of the outer drum 11 with the external space of the outer drum 11. When the garment handling device 100 executes the washing program and begins to fill water into the outer drum 11 and the inner drum, the connection between the internal and external spaces of the outer drum 11 ensures that the internal and external air pressures of the outer drum 11 are balanced, guaranteeing smooth water filling. During the washing process, when the water level or foam water level in the outer drum 11 rises, the sealing member 161 closes the through hole 1621, thereby preventing water or foam water in the outer drum 11 from flowing out through the through hole 1621.

[0030] According to the embodiment of the present invention, the clothing processing device 100 includes an anti-overflow device 16 comprising a sealing member 161. The sealing member 161 can open and close the through hole 1621. When the sealing member 161 opens the through hole 1621, the through hole 1621 can connect the inner and outer spaces of the outer cylinder 11, achieving pressure balance between the inner and outer sides of the outer cylinder 11. When the sealing member 161 closes the through hole 1621, it can prevent water or foam water in the outer cylinder 11 from flowing out through the through hole 1621. Compared with the clothing processing device 100 of the related technology, since the anti-overflow device 16 has the functions of air passage and anti-overflow, it is not necessary to separately open holes in the outer cylinder 11 to set up anti-overflow and air passage structures, which helps to simplify the structure of the clothing processing device 100 and improve the structural strength of the outer cylinder 11, thereby improving the reliability of the clothing processing device 100.

[0031] Reference Figure 1 , Figures 7-9According to some embodiments of this utility model, the outer cylinder 11 extends axially in the front-to-back direction or extends obliquely relative to the front-to-back direction. The outer cylinder 11 has a rear wall 111 and a side wall 112, with the side wall 112 surrounding the rear wall 111. The mounting port 115 is located on the upper part of the side wall 112. This arrangement helps to reduce the axial size of the outer cylinder assembly 10, enabling a miniaturized design of the clothing processing device 100, which is suitable for wall-mounted clothing processing devices.

[0032] Reference Figure 1 and further refer to Figures 12-14 In some embodiments, the upper part of the side wall 112 is provided with an air inlet 1101 and an air outlet 1102. The clothing processing device 100 also includes an air duct assembly 60, which is fixed to the outside of the outer cylinder 11 and defines the air outlet 601. The inlet 602 of the air duct 601 is connected to the air outlet 1102, and the outlet 603 of the air duct 601 is connected to the air inlet 1101.

[0033] In the circumferential direction of the outer cylinder 11, the air inlet 1101 and the main body of the air duct 601 are both located between the air outlet 1102 and the mounting port 115.

[0034] This arrangement ensures the structural strength of the side wall 112 of the outer cylinder 11 and extends the service life of the outer cylinder 11. On the other hand, it allows the air duct assembly 60 and the anti-overflow device 16 to be arranged circumferentially in the outer cylinder 11. This allows the shape of the housing assembly of the garment processing equipment 100 to be adapted to that of the outer cylinder assembly 10, thereby making the structure of the garment processing equipment 100 more compact and suitable for small wall-mounted garment processing equipment.

[0035] For example, the air outlet 1102 is located on the upper part of the outer cylinder 11 and is arranged in the left-right direction with the mounting port 115. For example, the outer cylinder 11 extends axially in the front-back direction or extends obliquely relative to the front-back direction. One of the air outlet 1102 and the mounting port 115 is located on the upper left part of the outer cylinder 11 and the other is located on the upper right part of the outer cylinder 11. The air inlet 1101 can be located in the middle of the outer cylinder 11 in the left-right direction.

[0036] According to some embodiments of this utility model, the outer cylinder assembly 10 has a vent hole, and the vent hole and the through hole 1621 are the same hole. That is to say, the through hole 1621 of the overflow prevention device 60 can be used for venting.

[0037] In some embodiments, the outer cylinder assembly 10 has a fresh air inlet, and the fresh air inlet and the vent hole are the same hole, that is, the vent hole 1621 of the overflow prevention device 60 can be used to vent fresh air.

[0038] Specifically, the air outside the outer cylinder 11 can flow towards the overflow prevention device 16 under the drive of aerodynamic components (such as a fan). The sealing member 161 opens the through hole 1621 under the action of airflow, that is, the sealing member 161 opens the fresh air hole under the action of airflow, so that the outside air can enter the outer cylinder 11 from the fresh air hole and regulate the temperature and humidity inside the outer cylinder 11.

[0039] Reference Figures 2-5 According to some embodiments of the present invention, the anti-overflow device 16 further includes a valve seat 162. That is, the anti-overflow device 16 includes a valve seat 162 and a sealing member 161. The valve seat 162 is disposed on the outer cylinder 11, and the through hole 1621 is disposed on the valve seat 162. The sealing member 161 is movably disposed on the side of the valve seat 162 facing the internal space of the outer cylinder 11. The sealing member 161 is configured to open the through hole 1621 under the action of gravity and close the through hole 1621 under the action of pressure inside the outer cylinder 11.

[0040] Specifically, in the initial or normal state, the sealing component 161 of the clothing treatment device 100 can open the through hole 1621 under the action of gravity, so that the internal space of the outer drum 11 and the external space of the outer drum 11 are connected, ensuring the balance of air pressure inside and outside the outer drum 11. In this way, when water is injected into the outer drum 11 and the inner drum, it can be guaranteed to be injected smoothly. During the washing process, when the water level or foam water level of the outer drum 11 rises, the sealing component 161 closes the through hole 1621 under the action of water pressure, thereby preventing water or foam water in the outer drum 11 from flowing out of the through hole 1621.

[0041] Therefore, by setting the valve seat 162, a through hole 1621 can be set on the valve seat 162, and the sealing component 161 can be installed on the valve seat 162, so that the valve seat 162, the sealing component 161 and other structures are combined to form a component, realizing a modular design of structure, which is convenient for assembly and disassembly. There is no need to process the fixing structure of the sealing component 161 on the outer cylinder 11, which helps to reduce the processing difficulty of the outer cylinder 11, simplify the structure of the outer cylinder 11, thereby reducing production costs and improving production efficiency.

[0042] Reference Figure 3 and Figure 4 In some embodiments, the sealing member 161 includes a connecting portion 1611 and a body portion 1612. The connecting portion 1611 is fixed to the side of the valve seat 162 facing the inner space of the outer cylinder 11, and the body portion 1612 is connected to one side of the connecting portion 1611. The body portion 1612 is deformable relative to the connecting portion 1611 to open and close the through hole 1621.

[0043] For example, the overall structure of the sealing element 161 can be made of a flexible material (such as rubber); or, the connecting portion 1611 of the sealing element 161 can be made of a flexible material. Of course, the sealing element 161 can also be made of other materials, which can be selected according to the actual situation.

[0044] In the above technical solution, by setting the sealing member 161 to include a connecting part 1611 and a body part 1612, and making the body part 1612 deformable relative to the connecting part 1611, the body part 1612 can open and close the through hole 1621. The structure is simple and the processing and manufacturing are relatively easy.

[0045] Reference Figure 5 In some examples, there are multiple vias 1621, which are arranged circumferentially at intervals in an imaginary circle. In the description of this utility model, "multiple" means two or more.

[0046] Furthermore, the body portion 1612 has a circular structure. When the sealing member 161 is in the state of closing the through hole 1621, the central axis of the body portion 1612 is perpendicular to the plane where the imaginary circle is located, and the center of the imaginary circle is located on the central axis of the body portion 1612.

[0047] Therefore, by setting multiple through holes 1621, the connection between the inner and outer spaces of the outer cylinder 11 can be ensured when the sealing member 161 opens the through holes 1621, so that the inner and outer spaces of the outer cylinder 11 can quickly achieve air pressure balance, thereby ensuring the water intake effect; by setting the body part 1612 as the above-mentioned circular structure, when the sealing member 161 closes the through holes 1621, the body part 1612 can completely cover the multiple through holes 1621, preventing water or foam water in the outer cylinder 11 from overflowing from the through holes 1621.

[0048] Reference Figure 6 In some examples, the body portion 1612 includes an end wall 16111 and a peripheral wall 16112. The peripheral wall 16112 of the body portion 1612 extends circumferentially along the end wall 16111 of the body portion 1612, and one end of the peripheral wall 16112 of the body portion 1612 is connected to the side of the end wall 16111 of the body portion 1612 away from the valve seat 162.

[0049] In some specific examples, the middle of the end wall 16111 of the body portion 1612 is recessed in a direction away from the valve seat 162, so that a cavity 16113 and an annular protrusion 16114 are formed on the side of the end wall 16111 of the body portion 1612 facing the valve seat 162. The annular protrusion 16114 extends circumferentially along the cavity 16113. When the sealing member 161 is in the state of closing the through hole 1621, the annular protrusion 16114 abuts against the valve seat 162, and the through hole 1621 is located in the area enclosed by the annular protrusion 16114.

[0050] In other words, when the sealing member 161 is in the state of closing the through hole 1621, the body part 1612 relies on the annular protrusion 16114 to stop and cooperate with the valve seat 162, so that the body part 1612 can cover the through hole 1621 and improve the overflow prevention effect.

[0051] Reference Figure 3 In some other specific examples, the end wall 16111 has a reinforcing rib 16115 on the side opposite to the valve seat 162, and both ends of the reinforcing rib 16115 are connected to the peripheral wall 16112.

[0052] For example, there can be multiple reinforcing ribs 16115, arranged in parallel and at intervals, with both ends of each reinforcing rib 16115 connected to the peripheral wall 16112 of the main body portion 1612; for example, one end of the reinforcing rib 16115 is close to the connecting portion 1611 and the other end extends away from the connecting portion 1611. Of course, the structure and number of reinforcing ribs 16115 can also be other, and can be selected according to the actual situation.

[0053] In the above technical solution, by providing a reinforcing rib 16115 on the side of the end wall 16111 away from the valve seat 162, the structural strength of the body part 1612 can be improved. In the example where one end of the reinforcing rib 16115 is close to the connecting part 1611 and the other end extends away from the connecting part 1611, the reinforcing rib 16115 can also support the body part 1612, so that the body part 1612 extends at an inclination relative to the plane where the through hole 1621 is located. Even if the through hole 1621 is slightly open, the body part 1612 is prevented from vertically downward, which would ultimately lead to the inability to close the through hole 1621.

[0054] Reference Figure 3 and Figure 6 In some specific examples, the middle part of the end wall 16111 of the body portion 1612 is recessed in a direction away from the valve seat 162, so that a cavity 16113 and an annular protrusion 16114 are formed on the side of the end wall 16111 of the body portion 1612 facing the valve seat 162. The annular protrusion 16114 extends circumferentially along the cavity 16113. When the sealing member 161 is in the state of closing the through hole 1621, the annular protrusion 16114 abuts against the valve seat 1622 and the through hole 1621 is located in the area enclosed by the annular protrusion 16114. The side of the end wall 16111 away from the valve seat 162 has a reinforcing rib 16115, and both ends of the reinforcing rib 16115 are connected to the peripheral wall 16112.

[0055] Reference Figure 3 and Figure 4In some embodiments, the anti-overflow device 16 further includes a fixing bracket 164, which is fixed to the side of the valve seat 162 facing the internal space of the outer cylinder 11.

[0056] In some examples, the sealing element 161 is snapped into connection with the fixing bracket 164. For instance, the sealing element 161 includes a connecting portion 1611 and a body portion 1612. The connecting portion 1611 is fixed to the side of the valve seat 162 facing the internal space of the outer cylinder 11, and the body portion 1612 is connected to one side of the connecting portion 1611. The body portion 1612 is deformable relative to the connecting portion 1611 to open and close the through hole 1621. The connecting portion 1611 is fixed to the side of the valve seat 162 facing the internal space of the outer cylinder 11 by the fixing bracket 164. One of the connecting portion 1611 and the fixing bracket 164 has a groove, and the other has a protrusion, which engages with the groove. Of course, the connection method between the sealing element 161 and the fixing bracket 164 is not limited to this; the specific method can be selected according to the actual situation.

[0057] In other examples, a portion of the plug 161 is sandwiched between the fixed bracket 164 and the valve seat 162. For example, the plug 161 includes a connecting portion 1611 and a body portion 1612. The connecting portion 1611 is fixed to the side of the valve seat 162 facing the internal space of the outer cylinder 11, and the body portion 1612 is connected to one side of the connecting portion 1611. The body portion 1612 is deformable relative to the connecting portion 1611 to open and close the through hole 1621. The connecting portion 1611 is at least partially sandwiched between the fixed bracket 164 and the valve seat 162, thereby securing the plug 161 to the valve seat 162.

[0058] In some other examples, the sealing element 161 is snapped into connection with the fixed bracket 164, with a portion of the sealing element 161 sandwiched between the fixed bracket 164 and the valve seat 162. This arrangement allows the fixed bracket 164 to secure the sealing element 161 to the side of the valve seat 162 facing the inner space of the outer cylinder 11, which improves the installation reliability of the sealing element 161. For example, the fixed bracket 164 is a strip structure. The two ends of the fixed bracket 164 in the length direction can be connected to the valve seat 162 by screws or other connectors. A part of the sealing member 161 is sandwiched between the middle part of the fixed bracket 164 in the length direction and the valve seat 162.

[0059] Reference Figures 4-6 In some embodiments, the anti-overflow device 16 further includes a valve cover 163, which is located on the side of the valve seat 162 away from the outer cylinder 11 and defines a cavity 1623 between the valve cover 163 and the valve seat 162. The through hole 1621 communicates with the external space of the outer cylinder 11 through the cavity 1623. The cavity 1623 is provided with a breathable and moisture-absorbing structure 1624.

[0060] Therefore, by setting a breathable and moisture-absorbing structure 1624 in the cavity 1623, on the one hand, when the sealing member 161 closes the through hole 1621, the breathable and moisture-absorbing structure 1624 can absorb the water or foam water entering the cavity 1623, further improving the overflow prevention effect of the overflow prevention device 16. On the other hand, since the breathable and moisture-absorbing structure 1624 is breathable, when the sealing member 161 opens the through hole 1621, the internal and external air pressure balance of the outer cylinder 11 can still be guaranteed, without affecting the water inlet.

[0061] Optionally, the breathable and moisture-wicking structure 1624 may include a sponge or other structure.

[0062] In some examples, one of the valve seat 162 and the valve cover 163 has a mounting post 1622 extending toward the other, and the breathable and moisture-absorbing structure 1624 is fitted onto the mounting post 1622. By providing the mounting post 1622, the breathable and moisture-absorbing structure 1624 can be positioned to prevent displacement within the cavity 1623, ensuring that the breathable and moisture-absorbing structure 1624 always covers the through hole 1621, further improving the overflow prevention effect of the anti-overflow device 16.

[0063] For example, mounting post 1622 is provided on valve seat 162 and extends toward valve cover 163, and breathable and moisture-absorbing structure 1624 is fitted on mounting post 1622.

[0064] For example, mounting post 1622 is provided on valve cover 163 and extends toward valve seat 162, and breathable and moisture-absorbing structure 1624 is fitted on mounting post 1622.

[0065] Reference Figure 5 In some examples, there are multiple vias 1621, which are arranged circumferentially at intervals in an imaginary circle, and the breathable and moisture-absorbing structure 1624 covers the multiple vias 1621. In the description of this utility model, "multiple" means two or more.

[0066] Therefore, by setting multiple through holes 1621, the connection between the inner and outer spaces of the outer cylinder 11 can be ensured when the sealing component 161 opens the through holes 1621, so that the inner and outer spaces of the outer cylinder 11 can quickly achieve air pressure balance, thereby ensuring the water intake effect.

[0067] Reference Figures 2-4 In some examples, the valve seat 162 has a plurality of connecting lugs 1625 and a plurality of connecting posts 1626, which are arranged alternately and at intervals in the circumference of the valve seat 162. Each connecting lug 1625 is connected to the outer cylinder 11 by a first fastener, and each connecting post 1626 is connected to the valve cover 163 by a second fastener.

[0068] Specifically, the valve seat 162 has a plurality of connecting lugs 1625, which are arranged at intervals around the circumference of the valve seat 162. The outer cylinder 11 has a plurality of mating posts 117, which correspond one-to-one with the positions of the plurality of connecting lugs 1625. Each connecting lug 1625 is connected to the mating post 117 at the corresponding position by a first fastener.

[0069] Furthermore, the valve seat 162 also has a plurality of connecting posts 1626, which are arranged at intervals in the circumference of the valve seat 162. The plurality of connecting posts 1626 and a plurality of connecting lugs 1625 are arranged alternately and at intervals in the circumference of the valve seat 162. The valve cover 163 has a plurality of mating lugs 1631, which correspond one-to-one with the positions of the plurality of connecting posts 1626. Each connecting post 1626 is connected to the mating lug 1631 at the corresponding position by a second fastener.

[0070] In the above technical solution, by setting multiple connecting lugs 1625, it is convenient to fix the valve seat 162 on the outer cylinder 11; by setting multiple connecting posts 1626, it is convenient to connect the valve seat 162 and the valve cover 163 together.

[0071] Reference Figures 2-5 The overflow prevention device 16 also includes a connecting pipe 166, one end of which is connected to the valve seat 162 and communicates with the cavity 1623, and the other end of which is adapted to be connected to the external space of the outer cylinder 11 or other pipelines.

[0072] When the laundry processing equipment 100 executes the washing program, it begins to fill water into the outer drum 11 and the inner drum. The air inside the outer drum 11 can pass through the through hole 1621 and be discharged to the external space of the outer drum 11 or other pipelines through the connecting pipe 166, so that the internal and external air pressure of the outer drum 11 is balanced, ensuring smooth water filling.

[0073] When the laundry processing equipment 100 is washing clothes, when the water level or foam water level of the outer drum 11 rises, the sealing member 161 closes the through hole 1621, thereby preventing water or foam water in the outer drum 11 from flowing out of the through hole 1621. Even if a small amount of water or foam water overflows, it can be discharged to the preset position through the connecting pipe 166.

[0074] Reference Figures 7-9 According to some embodiments of this utility model, the anti-overflow device 16 is detachably disposed at the mounting port 115. By installing the anti-overflow device 16 at the mounting port 115, both the air passage effect and the anti-overflow effect can be achieved by using the anti-overflow device 16. Since the anti-overflow device 16 is detachably connected to the outer cylinder 11, it is convenient for maintenance.

[0075] Reference Figure 9In some embodiments, the garment handling device 100 further includes a sealing ring 165 that extends circumferentially along the mounting opening 115 and is sandwiched between the outer cylinder 11 and the spill prevention device 16.

[0076] Therefore, by providing a sealing ring 165 between the outer cylinder 11 and the overflow prevention device 16, the connection sealing between the outer cylinder 11 and the overflow prevention device 16 can be improved, preventing water or foam water inside the outer cylinder 11 from flowing out from the gap between the outer cylinder 11 and the overflow prevention device 16.

[0077] Reference Figure 9 In some examples, one of the outer cylinder 11 and the spill prevention device 16 has an annular insertion portion 116 and the other has an annular slot 1627, with a sealing ring 165 disposed in the annular slot 1627. The annular insertion portion 116 is inserted into the annular slot 1627 and abuts against the sealing ring 165.

[0078] In the above technical solution, by setting an annular slot 1627 and an annular insertion part 116, the annular slot 1627 can be used to position the sealing ring 165, and the annular insertion part 116 can cooperate with the annular slot 1627 to realize the positioning and assembly of the overflow prevention device 16 and the outer cylinder 11, thereby improving the connection reliability and sealing performance between the overflow prevention device 16 and the outer cylinder 11. On the other hand, it can also press the sealing ring 165 to further improve the connection sealing performance between the overflow prevention device 16 and the outer cylinder 11.

[0079] Reference Figure 10 and Figure 11 In some embodiments, a limiting grille 1150 is provided inside the mounting port 115, and the sealing member 161 is located on the side of the limiting grille 1150 away from the internal space of the outer cylinder 11.

[0080] In the above technical solution, by setting a limiting grille 1150 inside the mounting port 115, the limiting grille 1150 can limit the sealing member 161, preventing it from extending vertically downwards and thus failing to properly close the through hole 1621. If the sealing member 161 falls off, it can also prevent it from falling between the outer cylinder 11 and the inner cylinder. Furthermore, it can improve the structural strength of the outer cylinder 11 and enhance its reliability. In addition, since the limiting grille 1150 has grille holes, it does not affect air passage.

[0081] For example, the limiting grille 1150 includes a plurality of horizontal ribs 1151 and a plurality of vertical ribs 1152, which are arranged in a cross pattern and define a plurality of through holes without affecting the air passage effect.

[0082] Reference Figures 18-20The garment processing equipment 100 also includes a filter element 64 and a rinsing assembly 63. The filter element 64 is located at the inlet 602 of the air duct 601. The rinsing assembly 63 is connected to the air duct assembly 60, and at least part of the rinsing assembly 63 is disposed in the air duct 601. The rinsing assembly 63 has a water spray section 6311 for spraying water toward the filter element 64.

[0083] Specifically, when the clothing processing equipment 100 dries clothes, the hot air in the air duct 601 can be discharged from the outlet 603 of the air duct 601 and enter the outer drum 11 through the air inlet 1101. After the hot air comes into contact with the wet clothes in the inner drum, the moisture in the clothes evaporates and forms humid air, which is then discharged from the air outlet 1102 of the outer drum 11 and enters the air duct 601 from the inlet 602. After being processed by the air duct assembly 60, it forms hot air again, and this cycle repeats. During this process, the filter element 64 can filter the airflow flowing through the inlet 602 of the air duct 601 to prevent impurities such as lint from entering the air duct 601. When it is necessary to clean the filter element 64, water can be passed through the rinsing assembly 64, so that the water spraying part 6311 can spray water towards the filter element 64 to clean the filter element 64. The water after cleaning the filter element 64 can enter the outer drum 11 and be discharged from the drain chamber of the outer drum 11 or through the external drain pipe.

[0084] Compared with the related technology that uses an air inlet ring to connect the air duct assembly and the outer cylinder, by directly connecting the inlet 602 of the air duct 601 to the outlet 1102 of the outer cylinder 11, and setting the filter element 64 at the inlet 602 of the air duct 601, the structure after the air duct assembly 60 and the outer cylinder 11 are connected can be more compact, which is conducive to improving the space utilization rate of the entire machine of the garment processing equipment 100. This allows for the miniaturization of the structure of the garment processing equipment 100. By setting at least part of the rinsing component 63 in the air duct 601, on the one hand, the rinsing component 63 can rinse the filter element 64 at the inlet 602 of the air duct 601, preventing impurities such as lint from entering the air duct 601 and the outer cylinder 11. On the other hand, it reduces the space occupied by the rinsing component 63, further improving the space utilization rate of the entire machine of the garment processing equipment 100.

[0085] Reference Figures 17-20 In some embodiments, the flushing assembly 63 includes a mounting bracket 631, which is located at the inlet 602 of the air duct 601, and the filter element 64 is mounted on the mounting bracket 631. Therefore, by including the mounting bracket 631 in the flushing assembly 631, the mounting bracket 631 can provide a mounting carrier for the filter element 64, allowing the filter element 64 to be installed at the inlet 602 of the air duct 601 via the mounting bracket 631. This makes installation and removal more convenient and improves the installation reliability and stability of the filter element 64.

[0086] The inner peripheral wall of the mounting bracket 631 is provided with a filter screen groove, and the periphery of the filter element 64 can be embedded in the filter screen groove.

[0087] In some embodiments, the water spray section 6311 is mounted on the mounting bracket 631. By mounting the water spray section 6311 on the mounting bracket 631, both the water spray section 6311 and the filter element 64 are located on the mounting bracket 631, that is, the water spray section 6311 and the filter element 64 are integrated into one unit. On the one hand, the structure can be more compact and the space utilization rate can be improved. On the other hand, modular design can be achieved, which is conducive to improving the assembly and disassembly efficiency.

[0088] Reference 17- Figure 21 In some examples, the mounting bracket 631 is a mounting ring, and the axial direction of the mounting ring is along a first direction (e.g., Figure 19 Extending in the F1 direction shown, the water spray section 6311 includes a water spray hole, and the water spray hole extends along the second direction (e.g., as shown in the F1 direction). Figure 19 The F2 direction (as shown) penetrates the peripheral wall of the mounting ring, and the second direction is set at an angle to the first direction. That is, the extension direction of the water spray part 6311 is set at an angle to the axial direction of the mounting ring. In the second direction, the water spray hole extends obliquely from the outside of the mounting ring to the inside of the mounting ring towards the filter element 64. In the above technical solution, by setting the water spray part 6311 on the mounting bracket 631, the relative position of the water spray part 6311 and the filter element 64 can be fixed. When installing the filter element 64, the positioning operation of the water spray part 6311 and the filter element 64 is eliminated, which helps to reduce the installation difficulty of the filter element 64, and also ensures the water spraying effect of the water spray part 6311 on the filter element 64, thereby ensuring the cleaning efficiency and cleaning effect of the filter element 64. In addition, by setting the water spray hole to extend obliquely from the outside of the mounting ring to the inside of the mounting ring towards the filter element 64, the water sprayed from the water spray hole can directly impact the filter element 64, thereby improving the cleaning efficiency and cleaning effect of the filter element 64.

[0089] Combined Figure 14 , Figures 19-20 The air duct assembly 60 is installed on the top of the outer cylinder 11. In this state, the first direction and the second direction are both inclined and extended in the vertical direction, and the water spray hole gradually extends from bottom to top towards the filter element 64. In this way, the water spray hole can spray water obliquely upward, so as to directly impact the filter element 64 and clean the filter element 64. The water on the filter element 64 can also extend the filter element 64 downward under the action of gravity, fully wet the filter element 64, and improve the cleaning effect of the filter element 64.

[0090] Reference Figures 15-21In some embodiments, the air duct assembly 60 includes an air duct seat 61 and an air duct cover 62. The air duct seat 61 is fixed to the outside of the outer cylinder 11, and the air duct cover 62 is located on the side of the air duct seat 61 away from the outer cylinder, defining an air duct 601 between the air duct cover 62 and the air duct seat 61. The inlet 602 of the air duct 601 is located on the air duct seat 61, and the mounting bracket 631 is located on the air duct seat 61. By configuring the air duct assembly 60 to include an air duct seat 61 and an air duct cover 62, the molding difficulty of the air duct assembly 60 can be simplified, production efficiency can be improved, and production costs can be reduced. On the other hand, it facilitates the installation of components such as the impeller.

[0091] Reference Figures 15-18 In some examples, the air duct assembly 60 is provided with a water inlet 632 communicating with the water spray section 6311. The water inlet 632 is located on the air duct seat 61 and is used to supply water to the water spray section 6311. By providing the water inlet 632, water can be supplied to the water spray section 6311, so that the water spray section 6311 can spray water toward the filter element 64, thereby cleaning the filter element 64 and preventing impurities such as lint from entering the air duct 601 and the outer cylinder 11.

[0092] In some specific examples, the water inlet 632 and the air duct seat 61 are integrally formed. By integrally forming the water inlet 632 and the air duct seat 61, on the one hand, the connection structure and connection operation between the water inlet 632 and the air duct seat 61 can be eliminated, thereby reducing production costs and improving the production efficiency of the garment processing equipment 100. On the other hand, it can improve the connection reliability between the water inlet 632 and the air duct seat 61, avoid water leakage at the connection point, reduce maintenance costs, and improve the user experience.

[0093] like Figures 17-19 As shown, in some examples, the air duct seat 61 has an air inlet ring 611 that defines the inlet 602 of the air duct 601, and the mounting bracket 631 is disposed inside the air inlet ring 611, that is, the air inlet ring 611 is sleeved on the outside of the mounting bracket 631.

[0094] The water inlet 632 is connected to the peripheral wall of the air inlet ring 611. The peripheral wall of the air inlet ring 611 is provided with a water passage hole 6111, which connects the water spray section 6311 and the water inlet 632. When it is necessary to clean the filter element 64, water can be supplied to the water inlet 632. The water in the water inlet 632 can flow through the water passage hole 6111 and finally be sprayed out from the water spray section 6311, thereby cleaning the filter element 64.

[0095] In the above technical solution, by placing the mounting bracket 631 inside the air inlet ring 611, it is convenient to connect the water spray section 6311 and the water inlet section 632, so that the water inlet section 632 can supply water to the water spray section 6311 to clean the filter element 64 and prevent impurities such as lint from entering the air duct 601 and the outer cylinder 11.

[0096] In some embodiments, the mounting bracket 631 is disposed in the inlet 602 of the air duct 601. The mounting bracket 631 is provided with a plurality of snap-fit ​​portions 6312 arranged circumferentially thereon. The inner peripheral wall of the inlet 602 of the air duct 601 is provided with a plurality of snap-fit ​​mating portions 6112 arranged circumferentially thereon. The plurality of snap-fit ​​portions 6312 are snap-fitted and connected to the plurality of snap-fit ​​mating portions 6112 in a one-to-one correspondence.

[0097] like Figure 17 and Figure 21 As shown, in this embodiment, the snap-fit ​​part 6312 can be an elastic buckle, and the snap-fit ​​mating part 6112 can be a slot. Multiple elastic buckles and multiple slots are snapped into each other in a one-to-one manner, thereby snapping the mounting bracket 631 into the inlet 602 of the air duct 601. Of course, the snap-fit ​​part 6312 and the snap-fit ​​mating part 6112 can also have other structural forms, which will not be listed here.

[0098] Therefore, by employing multiple snap-fit ​​parts 6312 and multiple snap-fit ​​mating parts 6112, the connection reliability between the mounting bracket 631 and the inner peripheral wall of the inlet 602 of the air duct 601 can be improved, ensuring the installation reliability and stability of the mounting bracket 631 within the inlet 602 of the air duct 601, preventing the filter element 64 from shifting under airflow impact, thus affecting the filtration effect of the filter element 64 and the cleaning effect of the filter element 64.

[0099] like Figure 17 , Figures 19-21 In some embodiments, one end of the mounting bracket 631 is provided with a mounting flange 6313, which extends circumferentially along the mounting bracket 631 and is supported on the inner surface of the air duct seat 61. In the above technical solution, by providing the mounting flange 6313, on the one hand, the mounting bracket 631 can be supported at the inlet 602 of the air duct seat 61, thereby achieving the positioning and installation of the filter element 64, preventing the filter element 64 from falling into the outer cylinder 11, and ensuring the filtration effect of the filter element 64. On the other hand, the mounting flange 6313 can improve the structural strength of the mounting bracket 631, prevent the mounting bracket 631 from deforming, and help improve the installation reliability and stability of the filter element 64, and further ensure the filtration effect of the filter element 64.

[0100] like Figure 21 and Figure 22As shown, in some examples, the inner surface of the duct seat 61 has a first positioning protrusion 612, and the mounting flange 6313 has a first positioning notch 6314, which engages with the first positioning protrusion 612. This allows for the positioning and installation of the filter element 64 at the inlet 602 of the duct 601, ensuring the reliability and stability of the filter element 64 installation and preventing the filter element 64 from rotating under airflow impact.

[0101] In the embodiment where the air duct seat 61 has a water passage hole 6111, the water passage hole 6111 can be provided on the first positioning protrusion 612. The water spray part 6311 and the first positioning notch 6314 are arranged opposite each other in the axial direction of the mounting bracket 631. When the filter element 64 is installed in the inlet 602 of the air duct 601, the positions of the water passage hole 6111, the water spray part 6311, the first positioning protrusion 612, and the first positioning notch 6314 correspond, so that the water passage hole 6111 and the water spray part 6311 can be connected when the first positioning protrusion 612 and the first positioning notch 6314 are engaged. Therefore, when installing the filter element 64, the engagement of the first positioning protrusion 612 and the first positioning notch 6314 can guide the installer, reducing the installation difficulty of the filter element 64.

[0102] In the embodiment where the water spray section 6311 is located on the mounting bracket 631, when the filter element 64 is installed in place in the inlet 602 of the air duct 601, the water spray section 6311 and the water inlet section 632 are in corresponding positions and connected. Therefore, in this embodiment, by providing the first positioning notch 6314 and the first positioning protrusion 612, it can be ensured that the water spray section 6311 and the water inlet section 632 are always in corresponding positions and connected, thereby ensuring the cleaning effect on the filter element 64.

[0103] like Figure 18 As shown, the water spray section 6311 includes spray holes, and the flow area of ​​the spray holes gradually increases in the water flow direction. For example, in a plane perpendicular to the flow surface of the water spray section 6311, the projected shape of the water spray section 6311 in that plane can be trapezoidal, fan-shaped, etc. This arrangement increases the spray range of the water spray section 6311, allowing the water sprayed from the water spray section 6311 to cover the filter element 64 as much as possible, reducing dead zones in the spray and improving the cleaning efficiency and effect of the filter element 64.

[0104] like Figure 19 As shown, the water spray unit 6311 includes water spray holes located on the air inlet or outlet side of the filter element 64. The extension direction of the water spray holes is inclined relative to the filter element 64 so that water is sprayed towards the filter element 64. By inclining the extension direction of the water spray unit 6311 relative to the filter element 64, the water sprayed from the water spray unit 6311 can directly impact the filter element 64, thereby improving the cleaning efficiency and cleaning effect of the filter element 64.

[0105] For example, the water spray section 6311 is located on the air inlet side of the filter element 64, that is, on the side of the filter element 64 facing the outer cylinder 11. The extending direction of the water spray section 6311 is inclined relative to the air inlet side of the filter element 64, and the water sprayed from the water spray section 6311 can clean the air inlet side of the filter element 64. For example, the water spray section 6311 is located on the air outlet side of the filter element 64, that is, on the side of the filter element 64 facing the air duct cover 62. The extending direction of the water spray section 6311 is inclined relative to the air outlet side of the filter element 64, and the water sprayed from the water spray section 6311 can clean the air outlet side of the filter element 64.

[0106] like Figure 17 , Figures 20-22 As shown, in some embodiments, a water guiding cavity 6113 is defined between the air duct seat 61 and the filter element 64. The water guiding cavity 6113 connects the air duct 601 and the inner cavity of the outer cylinder 11. Water in the air duct 601 (e.g., spray water, condensate water, washing water, etc.) can flow into the outer cylinder 11 through the water guiding cavity 6113 and eventually be discharged from the outer cylinder 11. By utilizing the water guiding cavity defined between the air duct seat 61 and the filter element 64, water in the air duct 601 can be guided to the outer cylinder 11 and eventually discharged to the outside, preventing bacteria from growing in the air duct 601 due to residual water.

[0107] In some examples, with the air duct assembly 60 installed on the outer cylinder 11, the water guide cavity 6113 is at the lowest position of the air duct 601, so that the water in the air duct 601 can be drained through the water guide cavity 6113.

[0108] In some examples, the water guiding cavity 6113 is located on the outer periphery of the inlet 602 of the air duct 601. The cavity wall of the water guiding cavity 6113 has a water guiding surface 6114. In the radial direction of the inlet 602 of the air duct 601, the water guiding surface 6114 gradually slopes downwards towards the inlet 602 of the air duct 601. Water in the air duct 601 can flow downwards under the guidance of the water guiding surface 6114, thereby entering the outer cylinder 11 and finally being discharged from the outer cylinder 11. In the above technical solution, by setting the water guiding surface 6114 on the cavity wall of the water guiding cavity 6113, a water guiding effect can be achieved, ensuring that the water in the air duct 601 can be completely drained through the water guiding cavity 6113, and preventing bacteria from growing in the air duct 601 due to residual water.

[0109] like Figure 12 , Figure 16 , Figures 19-20As shown, in some embodiments, the air duct assembly 60 includes a fan and a first heating element (not shown). The fan can be disposed within the air duct 601 near the inlet 602 of the air duct 601, and the first heating element can be disposed within the air duct 601 near the outlet 603 of the air duct 601. When drying clothes, the fan rotates, driving the airflow within the air duct 601 to form an airflow. The airflow is heated by the first heating element to form hot air.

[0110] In some examples, the duct assembly 60 includes a duct housing 604 that defines the duct 601. The duct housing 604 may include a volute 6041, a lateral extension 6042, and a longitudinal extension 6043. The lateral extension 6042 extends laterally or circumferentially along the outer cylinder 11, and the longitudinal extension 6043 extends axially along the outer cylinder 11. The lateral extension 6042 is disposed near the end wall of the outer cylinder 11 and is connected to one end of the volute 6041 and the longitudinal extension 6043 near the end wall of the outer cylinder 11.

[0111] The air duct 601 includes a fan cavity 60411, which is connected to the air outlet 1102 of the outer cylinder 11. The fan cavity 60411 is formed within the volute 6041, and the fan is rotatably disposed within the volute 6041. The first heating element can be disposed within the space defined by the longitudinal extension 6043. The air inlet 1101 of the outer cylinder 11 is located at the end of the outer cylinder 11 away from the end wall, and the end of the longitudinal extension 6043 away from the end wall of the outer cylinder 11 is connected to the air inlet 1101 of the outer cylinder 11.

[0112] Reference Figure 12 and Figure 13 In some specific examples, the outer cylinder 11 includes a cylinder body 1141 and a cylinder cover 1142. The cylinder cover 1142 is connected to the open end of the cylinder body 1141. The air inlet 1101 of the outer cylinder 11 is located on the cylinder cover 1142, and the air outlet 1102 of the outer cylinder 11 is located on the cylinder body 1141. The air duct assembly 60 is installed on the cylinder body 1141 and connected to the cylinder body 1141 and the cylinder cover 1142.

[0113] Reference Figure 12 and Figure 13The air inlet 1101 of the outer cylinder 11 has a circumferential dimension that gradually increases from the duct assembly 60 to the inner cavity of the outer cylinder 11. For example, the air inlet 1101 of the outer cylinder 11 is located above the outer cylinder 11, and the circumferential dimension of the air inlet 1101 of the outer cylinder 11 gradually increases from top to bottom. For example, the outer cylinder 11 includes a cylinder body 1141, a cylinder cover 1142, and an air inlet member. The air inlet member is connected to the upper part of the cylinder cover 1142 and defines the air inlet 1101. The air inlet member at least partially expands from top to bottom to define an air inlet 1101 with a flow area that gradually increases from top to bottom.

[0114] Because the mounting carrier of the air inlet 1101 (e.g., the cylinder cover 1141) has a small axial dimension in the outer cylinder 11, the axial dimension of the air inlet 1101 in the outer cylinder 11 is limited, meaning the distance between the two walls of the air inlet 1101 in the front-back direction is small, resulting in a small air intake volume of the air inlet 1101. Therefore, in the above technical solution, by setting the circumferential dimension of the air inlet 1101 of the outer cylinder 11 to gradually increase from the air duct assembly 60 to the inner cavity of the outer cylinder 11, even if the air inlet 1101 expands outward to both sides in the circumferential direction of the outer cylinder 11, the air intake volume of the air inlet 1101 can be increased, ensuring the drying efficiency of the garment processing equipment 100.

[0115] In some examples, the cylinder cover 1142 and the air inlet are integrally formed, which can eliminate the connection steps between the two, improve production efficiency, and also improve the reliability of the connection between the two.
