The inner drum is arranged inside the outer drum. The inner drum is mainly used to hold clothes, and the outer drum is the main structure of the entire clothes processing device. In the process of drying clothes, hot air circulates between the inner drum and the outer drum to dry clothes. However, hair debris may be generated during the drying process, and may enter the drying module with the flow of air, resulting in a poor drying effect. In order to prevent hair debris from entering the drying module, a filter is set in the air outlet channel to intercept the hair debris, and the filter is rinsed after the drying is completed. During the rinsing process, some water may flow back into the inner drum, wetting the clothes in the inner drum and affecting the drying effect. Summary of the invention

[0045] Clothes processing devices are widely used in daily life for washing or drying clothes. The clothes processing devices mainly include an inner drum and an outer drum. The inner drum is arranged inside the outer drum. The inner drum is mainly used to hold clothes, and the outer drum is the main structure of the entire clothes processing device. In the process of drying clothes, hot air circulates between the inner drum and the outer drum to dry clothes. In the drying process, the dry hot airflow enters the inner drum, takes away the moisture in the clothes to form a humid hot airflow. The humid hot airflow may condense and produce reflux water in the process of passing through the air outlet channel, which flows back to the cylinder through the air outlet channel, thereby wetting the clothes in the inner drum and affecting the drying effect. The outer drum and clothes processing device provided in the embodiment of the present application can improve the above-mentioned problems to a certain extent. The outer drum and clothes processing device provided in the embodiment of the present application can avoid the reflux water from flowing back to the inner drum as much as possible, so that the reflux water can be directly discharged through the drain pipe on the outer drum, thereby improving the overall drying effect.

[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] See also Figure 1 The embodiment of the present application provides an outer drum 100. The outer drum 100 provided in the embodiment of the present application can prevent the reflux water from flowing back to the inner drum 11 as much as possible, so that the reflux water can be directly discharged through the drain pipe on the outer drum 100, thereby improving the overall drying effect.

[0048] The outer drum 100 provided in the embodiment of the present application is mainly used in the clothing processing device 10. The outer drum 100 is the main structure of the overall clothing processing device 10, and can provide an installation basis for other structures of the clothing processing device 10. The drying module can be installed on the clothing processing device 10, and the inner drum 11 can be arranged inside the outer drum 100. During the drying process, a circulating airflow is formed between the inner drum 11 and the drying module to achieve the purpose of drying clothes.

[0049] See also Figure 2 and Figure 3 In the embodiment of the present application, the outer cylinder 100 includes: a cylinder body 110 and an outer shell 120, the cylinder body 110 has a accommodating chamber 112 and an air outlet 113 connected to the accommodating chamber 112, and the air outlet 113 is used to discharge the hot and humid air in the accommodating chamber 112 to the outside of the accommodating chamber 112; the outer shell 120 is arranged outside the accommodating chamber 112 and connected to the cylinder body 110, and the outer shell 120 has an air outlet channel 121 connected to the air outlet 113; wherein the accommodating chamber 112 has an opening 112a and a bottom surface 112b opposite to the opening 112a, the air outlet 113 is at least arranged on the bottom surface 112b of the cylinder body 110, and the lowest point of the air outlet 113 is adjacent to or flush with the lowest point of the bottom surface 112b, and the door seal 150 is arranged at the opening 112a.

[0050] The cylinder body 110 is the main body of the entire outer cylinder 100 , and can provide a mounting base for other components of the entire outer cylinder 100 , can install and accommodate other components of the outer cylinder 100 , and can protect and safeguard other components of the outer cylinder 100 .

[0051] The housing 120 is mainly connected between the outer drum 100 and the drying module of the laundry processing device 10, and is used to guide the air in the outer drum 100 to the drying module through the air outlet channel 121. The shape of the housing 120 can be set relative to the drum 110 and the drying module, and can be connected to the air outlet 113 of the drum 110 and the drying module.

[0052] For example; if the air outlet 113 is set at the bottom of the outer cylinder 100, the drying module is set at the top of the cylinder 110, one end of the outer shell 120 is connected to the air outlet 113, and the other end is connected to the drying module. The outer shell 120 can be set vertically or along the contour of the outer cylinder 100, as long as it can connect the air outlet 113 and the drying module.

[0053] The directions such as above, below, top, and bottom mentioned in the embodiments of the present application all refer to the positional relationship of the outer cylinder 100 in the working state.

[0054] It should also be noted that the bottom surface 112b refers to the side opposite to the opening 112a, that is, the bottom surface 112b refers to the wall opposite to the opening 112a, which is the bottom surface 112b, and is not the lowest end of the cylinder 110 during use. The bottom surface 112b may be the lowest end of the entire cylinder 110, or it may not be the lowest end of the cylinder 110.

[0055] For example, when the axis of the cylinder 110 is in the vertical direction, the bottom surface 112b is arranged below the opening 112a. When the axis of the cylinder 110 is in the horizontal direction, the bottom surface 112b and the opening 112a are both arranged vertically. If the opening 112a is arranged in front of the cylinder 110, the bottom surface 112b is arranged behind the cylinder 110. In the embodiments of the present application, the cylinder 110 axis is arranged horizontally as an example. The inner cylinder 11 is arranged in the accommodating chamber 112 and is arranged coaxially with the cylinder 110, that is, there is a certain gap between the outer peripheral surface of the inner cylinder 11 and the inner wall of the accommodating chamber 112.

[0056] At least part of the air outlet 113 is arranged on the bottom surface 112b. The air outlet 113 can be completely arranged on the bottom surface 112b, or part of the air outlet 113 can be arranged on the bottom surface 112b. The air outlet 113 can be arranged at other positions to ensure that the air outlet 113 can connect the accommodating cavity 112 and the air outlet channel 121.

[0057] In the embodiment of the present application, the lowest point of the air outlet 113 is close to or flush with the lowest point of the bottom surface 112b, which means that the lowest point of the air outlet 113 is close to the lowest point of the bottom surface 112b. When the backflow water enters the interior of the accommodating chamber 112 through the air outlet 113, the lowest point of the air outlet 113 is close to the lowest point of the bottom surface 112b, so that the backflow water can directly flow back to the lowest point of the bottom surface 112b, and there is a certain gap between the inner drum 11 and the inner wall of the accommodating chamber 112, so that there is also a certain gap between the lowest point and the inner drum 11. When the backflow water flows back to the lowest point of the bottom surface 112b, there is a certain gap with the inner drum 11, which can reduce the flow of the backflow water into the inner drum 11, thereby reducing the wetting or contamination of clothes by the backflow water, thereby improving the drying and cleaning effect of the clothes.

[0058] It should be noted that the lowest point of the bottom surface 112b refers to the lowest point of the bottom surface 112b in the vertical direction, and similarly, the lowest point of the air outlet 113 is also the lowest point of the air outlet 113 in the vertical direction. The air flow direction is from bottom to top, and the water flow direction should be from top to bottom.

[0059] In addition, the lowest point of the air outlet 113 is close to the lowest point of the bottom surface 112b, which means that the lowest point of the air outlet is located between the lowest point of the bottom surface 112b and the lowest point of the inner tube 11. That is, the lowest point of the air outlet 113 is not higher than the lowest point of the inner tube 11.

[0060] The outer drum 100 further includes a door seal 150 disposed at the opening 112 a . The door seal 150 is mainly used to cooperate with the door body of the laundry processing device 10 to seal the accommodating chamber 112 .

[0061] In some embodiments, the accommodating cavity 112 further has a side surface 112 c communicating with the opening 112 a and the bottom surface 112 b , and the air outlet 113 is disposed on both the bottom surface 112 b and the side surface 112 c .

[0062] The air outlet 113 is simultaneously arranged on the bottom surface 112b and the side surface 112c. Compared with the case where the air outlet 113 is only arranged on the bottom surface 112b, the area of ​​the opening 112a of the air outlet 113 can be increased. During the drying process of the clothing processing device 10, more airflow can enter the air outlet channel 121 through the air outlet 113, which can speed up the airflow circulation speed in the clothing processing device 10, thereby reducing the drying time and improving the drying effect.

[0063] Similarly, when water flows back into the cylinder 110 through the air outlet channel 121, the air outlet 113 is simultaneously arranged on the bottom surface 112b and the side surface 112c so that the opening 112a of the air outlet 113 is larger, and water can enter the bottom of the cylinder 110 at a slower flow rate, reducing the splashing of water in the cylinder 110, thereby also being able to reduce the risk of water entering the inner cylinder 11 to a certain extent.

[0064] The opening 112a and the bottom surface 112b are substantially vertically arranged, and the side surface 112c is substantially an annular structure, and there are multiple positions with different heights on the same circle of the side surface 112c.

[0065] In some embodiments, the side surface 112c has a water receiving surface 112d, the water receiving surface 112d is disposed at the lowest point of the side surface 112c, and the air outlet 113 extends to the water receiving surface 112d.

[0066] The water receiving surface 112d is arranged below the side surface 112c and is the lowest point on the overall side surface 112c. The air outlet 113 extends to the water receiving surface 112d, that is, the lowest point of the air outlet 113 is close to or flush with the water receiving surface 112d, that is, the lowest point of the air outlet 113 is not higher than the water receiving surface 112d. In the process of flushing the filter 130, after water enters the accommodating chamber 112 from the water outlet 126, it can flow into the water receiving surface 112d. Since the water receiving surface 112d is located at the lowest point of the side surface 112c, there is a certain gap between the water receiving surface 112d and the inner cylinder 11. When the water flow enters the accommodating chamber 112, it can be discharged to the outside of the cylinder body 110 through the water receiving surface 112d, thereby reducing the risk of water flowing into the inner cylinder 11, reducing the risk of clothes getting wet after drying, and improving the drying effect.

[0067] The water receiving surface 112d may be a plane, an inclined surface, or an irregular surface, and the specific shape of the water receiving surface 112d is not limited.

[0068] See also Figure 3 and Figure 4 In some embodiments, the bottom surface 112 b of the cylinder 110 has a mounting portion 114 , and the air outlet 113 and the mounting portion 114 are staggered, wherein the mounting portion 114 is used to mount the inner cylinder 11 , and the projection of the inner cylinder 11 on the bottom surface 112 b coincides with the mounting portion 114 .

[0069] The inner cylinder 11 is installed in the accommodating cavity and is coaxially arranged with the cylinder body 110, that is, the radius of the inner cylinder 11 is smaller than the radius of the cylinder body 110. The projection of the inner cylinder 11 on the bottom surface 112b is all located on the bottom surface 112b, and the projection of the inner cylinder 11 on the bottom surface 112b coincides with the mounting portion 114, and it can be considered that the projection of the inner cylinder 11 on the bottom surface 112b is the mounting portion 114. The air outlet 113 is staggered with the mounting portion 114, which means that the air outlet 113 is arranged at a position outside the projection of the inner cylinder 11 on the bottom surface 112b, that is, it can be considered that the air outlet 113 is staggered with the inner cylinder 11.

[0070] The air outlet 113 is offset from the inner drum 11. When the backflow water flows back into the accommodating chamber 112, the risk of the backflow water splashing into the inner drum 11 can be further reduced due to the offset arrangement of the air outlet 113 and the inner drum 11, and the risk of the backflow water wetting or dirtying the clothes can be reduced.

[0071] The air outlet 113 and the inner tube 11 are staggered, which means that the entire air outlet 113 is staggered with the inner tube 11 , and there is no part of the air outlet 113 that overlaps with the inner tube 11 .

[0072] In some embodiments, the air outlet 113 has a first connection side 113a and a second connection side 113b that are arranged on the bottom surface 112b and connected to each other. The lowest point of the air outlet 113 is located at an end of the second connection side 113b away from the first connection side 113a, and the shape of the first connection side 113a is adapted to the shape of the mounting portion 114.

[0073] The first connection side 113a is arranged above the air outlet 113, and the second connection side 113b is arranged approximately vertically. In the entire air outlet 113, the first connection side 113a is arranged closest to the inner tube 11, and the shape of the first connection side 113a is adapted to the shape of the mounting portion 114, which means that the shape of the first connection side 113a is adapted to the shape of the inner tube 11.

[0074] The shape of the first connecting side 113a is adapted to the shape of the inner cylinder 11, and may be the same as the outer contour of the inner cylinder 11. Since the first connecting side 113a is the top of the entire air outlet 113, when water flows to the air outlet 113, it may flow along the extension direction of the first connecting side 113a. The shape of the first connecting side 113a is the same as the outer contour of the inner cylinder 11, so that the water flow can always flow within the range before the outer contour of the inner cylinder 11, which can further reduce the risk of water splashing into the inner cylinder 11 and the risk of backflow water wetting or dirtying clothes.

[0075] Since the air outlet 113 and the inner tube 11 are staggered, there is a certain gap between the first connecting side 113 a and the outer contour of the inner tube 11 . Of course, the first connecting side 113 a can also be infinitely close to the outer contour of the inner tube 11 .

[0076] See also Figure 5 and Figure 6 In some embodiments, a guide surface 121 a is provided in the air outlet channel 121 , and the guide surface 121 a is connected to the first connection side 113 a and is adapted to the shape of the first connection side 113 a .

[0077] The drainage surface 121a is arranged in the air outlet channel 121, and the shape of the drainage surface 121a is adapted to the shape of the first connection side 113a, which also means that the shape of the drainage surface 121a is the same as the shape of the first connection side 113a. The first connection side 113a is arranged above the air outlet 113, and the drainage surface 121a is also arranged above the air outlet 113. When the water flows from top to bottom, the drainage surface 121a can play a role in draining the water flow, and can drain the water flow to the bottom of the water outlet 126, so as to avoid splashing of the water flow when entering the water outlet 126, so that the water flow can smoothly enter the accommodating cavity from the water outlet 126, thereby reducing the risk of the backflow water wetting or dirtying the clothes.

[0078] In some embodiments, a stop surface 121 b is disposed in the air outlet channel 121 , and the stop surface 121 b is connected to the second connection side 113 b .

[0079] Among them, the second connecting side 113b is roughly vertically arranged, and the stop surface 121b is also roughly vertically arranged. When the water flows from top to bottom, the stop surface 121b can play a certain flow-limiting role on the water flow, which can slow down the flow of the water flow, so that the water flow can enter the accommodating chamber 112 from the air outlet 113 at a lower speed, and the water flow can smoothly enter the accommodating chamber from the water outlet 126, thereby reducing the risk of backflow water wetting or dirtying clothes.

[0080] See also Figure 2 In some embodiments, the cylinder 110 includes a surrounding plate 115 and a bottom plate 116. The surrounding plate 115 is arranged around the bottom plate 116 to form a accommodating cavity 112 together with the bottom plate 116. The bottom surface 112b is arranged on one side of the bottom plate 116 located at the accommodating cavity 112. The outer shell 120 is connected to the other side of the bottom plate 116 and forms an air outlet channel 121 together with the bottom plate 116.

[0081] The bottom plate 116 is roughly circular, and the surrounding plate 115 is roughly cylindrical. The surrounding plate 115 is arranged on the bottom plate 116, and together with the bottom plate 116, a accommodating chamber 112 is formed. The outer shell 120 is connected to the bottom plate 116, and together with the bottom plate 116, an air outlet channel 121 is formed. The air outlet channel 121 can be formed by utilizing part of the structure of the bottom plate 116, so that the shape of the entire outer tube 100 can be made more compact.

[0082] See also Figure 6 and Figure 7 In some embodiments, the housing 120 includes a rear panel 123 and a plurality of side panels 124 , wherein the plurality of side panels 124 are respectively connected to different sides of the rear panel 123 and are connected to the bottom panel 116 , and the bottom panel 116 , the rear panel 123 and the plurality of side panels 124 together form an air outlet channel 121 .

[0083] The number of the side panels 124 is the same as the number of the sides of the rear panel 123. For example, if the rear panel 123 is a quadrilateral, the rear panel 123 has four sides. Accordingly, four side panels 124 are also provided, and one side panel 124 is connected to one side of the rear panel 123 and the cylinder 110. Of course, the shape of the side panel 124 should be the same as the shape of the side of the rear panel 123, so that the entire housing 120 can form a relatively regular structure.

[0084] One of the side panels 124 is located at the lower part of the entire rear panel 123, and it can also be considered that the side panel 124 is arranged at the end below the rear panel 123. For the convenience of description, the side panel 124 can be defined as a stopper 128. The stopper 128 is arranged substantially vertically, and the stopper surface 121b is arranged on the stopper 128. The water flow direction is along the extension direction of the rear panel 123, and the air outlet 113 is arranged on the bottom plate 116, so that the water flow direction in the air outlet channel 121 is different from the water flow direction entering the accommodating chamber. The stopper 128 is arranged at the end of the rear panel 123, which can block the water flow in the direction of the water flow, slow down the flow rate of the backflow water entering the accommodating chamber 112, and enable the water flow to smoothly enter the accommodating chamber from the water outlet 126, thereby reducing the risk of the backflow water wetting or dirtying the clothes.

[0085] In some embodiments, a guide plate 129 is disposed in the air outlet channel 121 . The guide plate 129 is disposed at the air outlet 113 , and at least a portion of the shape of the guide plate 129 is adapted to the shape of the air outlet 113 .

[0086] The guide plate 129 is arranged in the air outlet channel 121, and at least part of the shape of the guide plate 129 is adapted to the shape of the air outlet 113, which means that at least part of the shape of the guide plate 129 is the same as at least part of the outer contour of the air outlet 113. The guide plate 129 is arranged at the air outlet 113. When the water flows in the air outlet channel 121 to the air outlet 113, the guide plate 129 can play a certain drainage role on the water flow, so that the water flow can enter the accommodating chamber 112 more smoothly, thereby reducing the risk of the backflow water wetting or dirtying the clothes.

[0087] The guide surface 121 a is disposed on the guide plate 129 . In addition, the guide plate 129 may not be provided, and the guide surface 121 a may be disposed on one of the side plates 124 .

[0088] Since the guide plate 129 is arranged in the air outlet channel 121, the guide plate 129 and the adjacent side plate 124 are spaced apart, so that there is an ineffective cavity where no water flows between the guide plate 129 and the side plate 124. Although no water flows through, the contact area between the entire outer shell 120 and the bottom plate 116 can be increased, thereby improving the fixing effect of the outer shell 120.

[0089] In some embodiments, the outer tube 100 further includes an end cover 140 and a filter 130 disposed in the outlet tube belt 121 , and an inspection port 122 is disposed on one end of the outer shell 120 close to the filter 130 . The end cover 140 is detachably connected to the outer shell 120 , and the inspection port 122 can be opened or closed.

[0090] The inspection port 122 is mainly used for disassembling and assembling the filter 130, so that the filter 130 can be removed from the air outlet channel 121 through the inspection port 122 or installed from the inspection port 122 to the air outlet channel 121. Therefore, the width of the inspection port 122 in at least one direction should be greater than the minimum width of the filter 130, so as to facilitate the disassembly and assembly of the filter 130 through the inspection port 122.

[0091] The filter 130 is arranged in the air outlet channel 121, that is, arranged on the path of the air flow in the air outlet channel 121, and is mainly used to filter the hair in the air flow. The filter 130 is arranged in the air outlet channel 121 in a transverse manner, and can fill the entire cross section of the air outlet channel 121 in the air flow direction, so that the air flow passing through the air outlet channel 121 can be filtered by the filter 130, and the hair is prevented from entering the drying module. After the drying is completed, the filter 130 is rinsed, and during the rinsing process, some water may flow back into the inner drum 11.

[0092] When flushing the filter 130, the clean water after flushing enters the interior of the accommodating chamber 112 through the air outlet 113. The lowest point of the air outlet 113 is not higher than the lowest point of the bottom surface 112b, so that the clean water can directly flow back to the lowest point of the bottom surface 112b, and there is a certain gap between the inner drum 11 and the inner wall of the accommodating chamber 112, so that there is also a certain gap between the lowest point and the inner drum 11. When the clean water flows back to the lowest point of the bottom surface 112b, there is a certain gap with the inner drum 11, which can reduce the flow of clean water into the inner drum 11, thereby reducing the wetting or contamination of clothes by the clean water, thereby improving the drying and cleaning effects of the clothes.

[0093] That is, the return water includes condensed water and clean water of the filter 130 .

[0094] The end cap 140 is arranged at the inspection port 122, and is mainly used to seal the inspection port 122, so as to prevent external impurities from entering the air outlet channel 121 and the drying module to affect the operation of the drying module. In addition, the problem of water leakage during the flushing of the filter screen 130 can be avoided as much as possible.

[0095] In the embodiment of the present application, the inspection port 122 is set at one end of the filter 130. When the filter 130 is removed, the inspection port 122 is exposed, and the hand can be inserted into the air outlet passage 121, holding one end of the filter 130, and the filter 130 can be directly pulled out from the inspection port 122. Similarly, when installing the filter 130, the other end of the filter 130 is first inserted into the air outlet passage 121 from the inspection port 122 until the filter 130 is completely installed in the air outlet passage 121. The inspection port 122 is set at one end of the filter 130. In the process of disassembling and assembling the filter 130, there is no need to connect the filter 130 and the inspection port 122, and the filter 130 can be directly disassembled and assembled, which can reduce the operation of the filter 130 during the disassembly and assembly process, making the disassembly and assembly operation faster and easier, and can reduce the time for disassembling and assembling the filter 130, thereby improving the disassembly and assembly efficiency.

[0096] In some embodiments, the housing 120 includes a rear panel 123 and a plurality of side panels 124 , the plurality of side panels 124 are respectively connected to different sides of the rear panel 123 , the rear panel 123 and the plurality of side panels 124 form an air outlet channel 121 , and an inspection port 122 is disposed on the rear panel 123 .

[0097] The side plate 124 connects the drum 110 and the rear plate 123, that is, the rear plate 123 and the drum 110 are arranged opposite to each other, that is, the rear plate 123 is the rearmost of the entire clothing processing device 10, and the inspection port 122 is arranged on the rear plate 123, which can facilitate the disassembly and assembly of the filter 130. At the same time, the surface area of ​​the rear plate 123 is larger than the surface area of ​​any side plate 124, and the inspection port 122 is arranged on the rear plate 123, so that the inspection port 122 can be arranged large enough to facilitate the disassembly and assembly of the filter 130.

[0098] In some embodiments, the filter 130 is tilted relative to the rear plate 123 , and the filter 130 has a first end 132 and a second end 134 that are relatively disposed, the first end 132 is disposed close to the rear plate 123 , the second end 134 is disposed away from the rear plate 123 , and the inspection port 122 is disposed close to the first end 132 .

[0099] The filter 130 is tilted relative to the rear plate 123, that is, the entire filter 130 is tilted in the air outlet channel 121. The tilted filter 130 can increase the setting area of ​​the filter 130 in the air outlet channel 121, increase the contact area between the filter 130 and the airflow, and can improve the filtering effect to a certain extent.

[0100] The side plate 124 is connected to the cylinder 110, that is, the first end 132 is arranged close to the rear plate 123, and the second end 134 is arranged close to the cylinder 110. In the first end 132 and the second end 134, the inspection port 122 is arranged closer to the first end 132. It can be considered that the inspection port 122 is arranged at the first end 132, so that the distance between the inspection port 122 and the filter 130 is closer. In the process of disassembling the filter 130, after the end cover 140 is removed from the inspection port 122, the filter 130 can be exposed from the inspection port 122. During disassembly, the maintenance personnel can put their fingers into the air outlet channel 121 to hold the filter 130, which can further reduce the difficulty of disassembling the filter 130 and improve the convenience of disassembling the filter 130, thereby reducing the disassembly time of the filter 130 and improving the disassembly and assembly efficiency of the filter 130.

[0101] See also Figure 8 In some embodiments, the housing 120 has a water flow channel 125 , the water flow channel 125 has a water outlet 126 connected to the air outlet channel 121 , and the inspection port 122 is disposed near the water outlet 126 .

[0102] After the clothes processing device 10 dries the clothes, water can be discharged from the water outlet 126 to clean the filter 130. It should be noted that the water flow direction is opposite to the air flow direction, so that the hair on the filter 130 can be cleaned and washed away. For example, in the working state, the air flow direction is from bottom to top, then the water flow direction should be from top to bottom, and the water outlet 126 should be set on the side of the filter 130 close to the drying module.

[0103] Among them, compared with other positions of the air outlet channel 121, the water pressure is smaller at a position closer to the water outlet 126, and the water pressure is greater at a position closer to the bottom of the air outlet channel 121. The inspection port 122 is arranged close to the water outlet 126, so that the water pressure at the inspection port 122 is smaller, which can reduce the sealing pressure of the end cover 140 on the inspection port 122, minimize the leakage of water from the inspection port 122 during the flushing process of the filter screen 130, and improve the sealing effect of the end cover 140 on the inspection port 122.

[0104] Of the first end 132 and the second end 134, the first end 132 is arranged closer to the water outlet 126. Since the inspection port 122 is arranged at the first end 132 of the filter 130, it means that the distance between the inspection port 122 and the water outlet 126 is relatively close. The inspection port 122 is roughly arranged at a position close to the top of the entire shell 120. In the air outlet channel 121, the direction of water flow is from the water outlet 126 to the air outlet 113 at the bottom. The inspection port 122 is arranged above the shell 120, so that the water pressure at the inspection port 122 is less than the water pressure at the air outlet 113, and the water pressure borne by the end cover 140 is also relatively small, which reduces the risk of water leakage from the inspection port 122, thereby improving the sealing effect of the end cover 140 on the inspection port 122.

[0105] In some embodiments, the inspection port 122 is disposed below the water outlet 126 .

[0106] It should be noted that the inspection port 122 is disposed below the water outlet 126, which means that when the clothes processing device 10 is in use or in working condition, the inspection port 122 is disposed below the water outlet 126. The inspection port 122 is disposed below the water outlet 126, and the inspection port 122 is disposed at the first end 132 of the filter 130, which means that the filter 130 is also disposed below the water outlet 126. The filter 130 is disposed below the water outlet 126, so that the water can flow to the filter 130 under the action of its own gravity, and the hair on the filter 130 can be flushed by the water pressure and its own gravity, which can improve the flushing effect.

[0107] Similarly, the entire water flow channel 125 and the inspection port 122 are arranged on the same side of the housing 120 , both arranged on the side of the rear plate 123 , which can provide more flow space for the water flow and improve the flushing effect on the filter 130 .

[0108] In some embodiments, the water flow channel 125 is tilted toward the filter 130 so that the water outlet 126 is disposed in the housing 120 , and at least a portion of the end cover 140 extends into the housing 120 to seal the gap between the water outlet 126 and the inspection port 122 .

[0109] The water flow channel 125 is inclined relative to the outer shell 120, so that the water flowing out of the water outlet 126 can have a certain inclined direction, so that the water flow can flow to a farther place, and can flush different positions of the filter 130, thereby reducing the dead corners of the water flow cleaning the filter 130 as much as possible, and improving the cleaning effect of the filter 130.

[0110] The filter 130 is tilted relative to the shell 120, and the water flow channel 125 is also tilted relative to the shell 120. The tilt directions of the two can be different or the same. The tilt angles of the filter 130 and the water flow channel 125 relative to the shell 120 can be set according to actual conditions.

[0111] Since the water flow channel 125 is inclined compared to the outer shell 120, there is a step surface 127 connected to the inspection port 122 below the water outlet 126. In addition, the water flow channel 125 is inclined compared to the outer shell 120, so that the water outlet 126 is at a certain distance from the back plate 123, and there is a certain distance between the water outlet 126 and the inspection port 122. In order to prevent water from leaking from the inspection port 122, part of the end cover 140 needs to extend into the air outlet channel 121 and be able to extend to the water outlet 126, that is, the end cover 140 needs to contact the step surface 127 below the water outlet 126, thereby increasing the contact area between the end cover 140 and the inner wall of the inspection port 122 and the step surface 127, and increasing the sealing distance of the end cover 140, thereby enhancing the sealing effect of the inspection port 122.

[0112] The above mainly describes the specific positions of the end cover 140 and the inspection port 122 on the housing 120, and the positional relationship between the inspection port 122 and the filter 130 and the water outlet 126. The specific structure of the end cover 140 and how the end cover 140 seals the inspection port 122 will be specifically introduced below.

[0113] See also Figure 3 and Fig. 9 In some embodiments, the end cover 140 includes a cover plate 142 and a plug 143, the plug 143 is connected to the cover plate 142, the cover plate 142 is arranged outside the shell 120, the plug 143 is passed through the inspection port 122, and the cover plate 142 is detachably connected to the shell 120.

[0114] The end cover 140 includes two parts, a cover plate 142 and a plug 143. The cover plate 142 is arranged outside the air outlet channel 121, and most of the structure of the plug 143 is arranged inside the air outlet channel 121. The cover plate 142 mainly plays a connecting and fixing role, while the plug 143 mainly plays a sealing role, sealing the gap between the water outlet 126 and the inspection port 122 to avoid water leakage of the inspection port 122 as much as possible.

[0115] As for the connection between the cover plate 142 and the rear plate 123 , the connection may be fixed by means of screws or by means of snap connections, and the specific structure is not limited.

[0116] For example: when the cover plate 142 and the rear plate 123 are fixed with screws, a first fixing hole 142a can be set on the cover plate 142, and a second fixing hole can be set on the rear plate 123. Screws, bolts or studs are inserted into the first fixing hole 142a and the second fixing hole to fix the cover plate 142 and the rear plate 123.

[0117] In addition, a disassembly hole 142b may be provided on the cover plate 142. When the cover plate 142 needs to be disassembled from the rear plate 123, a tool (such as a screwdriver, a rope, a pull ring, etc.) may be inserted into the disassembly hole 142b to disassemble the cover plate 123. The disassembly hole 142b is mainly pierced by a tool, and the diameter of the disassembly hole 142b may be set relatively large, and may be larger than the first fixing hole 142a.

[0118] In some embodiments, the plug portion 143 includes a sealing end 143 a and a connecting end 143 b that are oppositely disposed, the connecting end 143 b is engaged with the side wall of the inspection opening 122 , and the sealing end 143 a is in contact with the side wall of the inspection opening 122 .

[0119] The sealing end 143a abuts against the side wall of the inspection port 122, and the entire plug portion 143 can be made of an elastic material, which can be silicone, rubber or other materials. The sealing end 143a will be deformed during the abutment with the side wall of the inspection port 122, so that the sealing end 143a can be in close contact with the side wall of the inspection port 122, and the connecting end 143b is clamped with other positions of the inspection port 122. The connection is connected by clamping, which can facilitate the assembly of the plug portion 143 and the inspection port 122.

[0120] During the assembly process, the connection end 143b can be first engaged with the side wall, and then the entire plug 143 is pushed into the inspection port 122. During the pushing process, the sealing portion 143h contacts the inner wall of the inspection port 122 and the step surface 127, and deforms until the entire plug 143 is located in the air outlet channel 121, and then the cover plate 142 is fixed to the housing 120, so that the entire end cover 140 is installed on the housing 120. This installation method only requires first engaging the connection end 143b with the side wall of the inspection port 122, and then fixing the cover plate 142 and the housing 120, which is simple and convenient to operate.

[0121] In some embodiments, of the sealing end 143 a and the connecting end 143 b , the sealing end 143 a is disposed close to the water outlet 126 .

[0122] The sealing end 143a is arranged near the water outlet 126, and the connecting end 143b is arranged far away from the water outlet 126, that is, the sealing end 143a is arranged above the connecting end 143b, and the connecting end 143b is mainly used to connect with the inspection port 122, and the sealing end 143a is mainly used to seal the gap between the inspection port 122 and the water outlet 126. The entire plug portion 143 can be made of elastic material, and the elastic material can be materials such as silicone or rubber. The sealing end 143a will deform during the abutment process with the side wall of the inspection port 122 and the step surface 127, so that the sealing end 143a and the side wall of the inspection port 122 and the sealing portion 143h and the step surface 127 can be in close contact, thereby improving the sealing effect between the inspection port 122 and the water outlet 126.

[0123] In some embodiments, the thickness of the sealing end 143a is greater than the thickness of the connecting end 143b.

[0124] Since the water flow channel 125 is tilted inwardly relative to the rear plate 123, there is a certain distance between the water outlet 126 and the rear plate 123. The sealing end 143a mainly seals the gap between the water outlet 126 and the inspection port 122. The sealing end 143a should be set thicker and try to be the same as the distance between the water outlet 126 and the inspection port 122 outside the shell 120, so as to increase the sealing distance of the entire sealing part 143h and improve the sealing effect.

[0125] Since the connecting end 143b mainly fixes the plug portion 143, there is no need for sealing. It can ensure that the connecting end 143b is snap-fitted with the inspection port 122. The thickness of the connecting end 143b can be set relatively small, which can save the material of the plug portion 143 and reduce the manufacturing cost of the end cover 140 to a certain extent.

[0126] In some embodiments, the plug portion 143 has an inclined avoidance surface 143c, and the avoidance surface 143c connects the sealing end 143a and the connecting end 143b.

[0127] Since the thickness of the connecting end 143b is less than that of the sealing end 143a, in order to make the entire plug 143 have a smooth transition, the sealing end 143a and the connecting end 143b can be connected by the avoiding surface 143c. In addition, by avoiding the inclined surface setting, part of the air outlet channel 121 can be avoided, so that the space below the plug 143 is left for the air outlet channel 121, which is convenient for the airflow to pass from below, and can also reduce the influence of the plug 143 on the airflow to a certain extent.

[0128] It should be noted that, in some embodiments, the avoidance surface 143c is roughly rectangular, and the sealing end 143a and the connecting end 143b are respectively arranged on two opposite sides of the avoidance surface 143c, and the two opposite sides of the avoidance surface 143c can be defined as transition ends 143f, and the two transition ends 143f are respectively connected to the two ends of the sealing end 143a and the connecting end 143b.

[0129] In some embodiments, in the plug portion 143 , at least the connecting end 143 b has a flange 143 d , and a gap between the flange 143 d and the connecting end 143 b forms a slot 143 e , which is engaged with a side wall of the inspection opening 122 .

[0130] That is, there is a slot 143e at the connection end 143b, and when installing, the side wall of the inspection opening 122 is clamped in the slot 143e, which can play a certain role in limiting and fixing the plug 143. At the same time, the flange 143d overlaps with the rear plate 123 at the inspection opening 122, which can cover the gap between the plug 143 and the side wall of the inspection opening 122, and can also play a certain sealing role.

[0131] Among them, at least the connecting end 143b has the flange 143d, which means that only the connecting end 143b has the flange 143d, or the connecting end 143b and one of the transition ends 143f have the flange 143d at the same time, or the connecting end 143b and two transition ends 143f have the flange 143d at the same time.

[0132] In some embodiments, the outer peripheral surface of the plug portion 143 has a plurality of sealing portions 143 h (such as sealing ribs) disposed at intervals, and the sealing portions 143 h abut against the side wall of the inspection port 122 to form an interference fit to seal the inspection port 122 .

[0133] The sealing portion 143h is annularly arranged on the outer circumference of the plug portion 143, and the sealing end 143a is convexly arranged on the outer circumference of the plug portion 143, and can abut against the inner wall of the inspection port 122 to seal the inspection port 122. Multiple sealing portions 143h are sequentially arranged in a direction close to the cover plate 142. The multiple sealing portions 143h can form a multi-stage seal for the inspection port 122, further improving the sealing effect.

[0134] The protruding heights of the plurality of sealing portions 143 h relative to the plug portion 143 may be the same or different and may be set according to the shape between the step surface 127 below the air outlet 113 and the side wall of the inspection port 122 .

[0135] In summary, in the outer cylinder 100 provided in the embodiment of the present application, the lowest point of the air outlet 113 is close to or flush with the lowest point of the bottom surface 112b, which means that the lowest point of the air outlet 113 is not higher than the lowest point of the bottom surface 112b. When the backflow water enters the interior of the accommodating cavity 112 through the air outlet 113, the lowest point of the air outlet 113 is not higher than the lowest point of the bottom surface 112b, so that the backflow water can directly flow back to the lowest point of the bottom surface 112b, and there is a certain gap between the inner cylinder 11 and the inner wall of the accommodating cavity 112, so that there is also a certain gap between the lowest point and the inner cylinder 11. When the backflow water flows back to the lowest point of the bottom surface 112b, there is a certain gap with the inner cylinder 11, which can reduce the flow of the backflow water into the inner cylinder 11, thereby reducing the wetting or contamination of clothes by the backflow water, thereby improving the drying and cleaning effect of the clothes.

[0136] Based on the same inventive concept, the embodiment of the present application also provides a clothing processing device 10. The clothing processing device 10 provided in the embodiment of the present application can avoid the backflow water from flowing back to the inner drum 11 as much as possible, so that the water cleaning the filter 130 can be directly discharged through the drain pipe on the outer drum 100, thereby improving the overall drying effect.

[0137] In the embodiment of the present application, the clothes processing device 10 comprises an inner drum 11 and the outer drum 100, and the inner drum 11 is arranged in the accommodating chamber 112. The clothes processing device 10 may be a clothes dryer, a drying machine, or a washing and drying machine.
