[0003] This application publicly claims priority to Chinese patent application No. 202311340252.4 filed on October 16, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0004] The present disclosure relates to a laundry processing device, and in particular to an outer drum, a laundry processing device, a control method and device for the laundry processing device, and a readable storage medium. Background Art

[0005] Clothes processing devices are widely used in daily life for washing or drying clothes. Clothes processing devices mainly include an inner drum and an outer drum. The inner drum is arranged inside the outer drum and is mainly used to hold clothes. The outer drum is the main structure of the entire clothes processing device. During the process of drying clothes, hot air circulates between the inner drum and the outer drum to dry the clothes. However, lint may be generated during the drying process. With the flow of air, it may enter the drying module, resulting in a poor drying effect. To prevent lint from entering the drying module, a filter is installed in the air outlet channel to intercept the lint. After drying, the filter is rinsed. 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.

[0006] Summary of the Invention

[0007] The present disclosure aims to at least to some extent solve the technical problem of poor clothes drying effect. To this end, the present disclosure provides an outer drum and a clothes processing device.

[0008] In a first aspect, one or more embodiments of the present disclosure provide an outer cylinder, comprising:

[0012] In some embodiments, the air outlet is at least provided on the bottom surface of the cylinder, and the lowest point of the air outlet is adjacent to or flush with the lowest point of the bottom surface.

[0013] If the lowest point of the air outlet is close to or flush with the lowest point of the bottom surface, it means that the lowest point of the air outlet is close to or not higher than the lowest point of the bottom surface. When the return water enters the interior of the accommodating chamber through the air outlet, the lowest point of the air outlet is not higher than the lowest point of the bottom surface, so that the return water can directly return to the lowest point of the bottom surface. There is a certain gap between the inner drum and the inner wall of the accommodating chamber, so that there is also a certain gap between the lowest point of the bottom surface and the lowest point of the inner drum, with a certain height difference. When the return water flows back to the lowest point of the bottom surface, the height of the lowest point of the bottom surface is lower than the height of the lowest point of the inner drum, so that the return water can be discharged through the lowest point of the bottom surface, which can minimize the return water from flowing into the inner drum, thereby reducing the return water from wetting or contaminating clothes, thereby improving the drying and cleaning effect of clothes.

[0014] In a second aspect, one or more embodiments of the present disclosure provide a laundry processing device, comprising an inner drum and the outer drum provided in the first aspect, wherein the inner drum is disposed in the accommodating cavity.

[0071] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only for the purpose of illustrating the basic principles of the present invention and is not intended to limit the present invention.

[0072] Clothes processing devices are widely used in daily life for washing or drying clothes. 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. During the process of drying clothes, hot air circulates between the inner drum and the outer drum to dry the clothes. During the drying process, the dry hot air flow enters the inner drum, takes away the moisture in the clothes and forms a humid hot air flow out. The humid hot air flow may condense and produce reflux water in the process of passing through the air outlet channel, which flows back to the drum 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 disclosure can improve the above-mentioned problem to a certain extent. The outer drum and clothes processing device provided in the embodiment of the present disclosure can avoid the reflux water from flowing back to the inner drum as much as possible, so that the reflux water can be discharged directly through the drain pipe on the outer drum, thereby improving the overall drying effect.

[0073] The present disclosure is described below with reference to the accompanying drawings and specific embodiments:

[0074] Please refer to Figure 1. An embodiment of the present disclosure provides an outer drum 100. The outer drum 100 provided in the embodiment of the present disclosure can prevent the backflow water from flowing back to the inner drum 11 as much as possible, so that the backflow water can be directly discharged through the drain pipe on the outer drum 100, thereby improving the overall drying effect.

[0075] The outer drum 100 provided in the embodiment of the present disclosure is mainly used on the clothing processing device 10. The outer drum 100 is the main structure of the entire clothing processing device 10 and can provide an installation basis for other structures of the clothing processing device 10. The drying module 21 can be installed on the clothing processing device 10 and can be installed on the outer drum 100. 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 21, thereby achieving the purpose of drying clothes.

[0076] Please refer to Figures 2 and 3. In the embodiment of the present disclosure, 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. 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. The outer shell 120 has an air outlet channel 121 connected to the air outlet 113; in some embodiments, 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. The door seal 150 is arranged at the opening 112a.

[0077] In some embodiments, the barrel 110 is the main body of the entire outer barrel 100 and can provide a mounting base for other components of the entire outer barrel 100 , can install and accommodate other components of the outer barrel 100 , and can protect and safeguard other components of the outer barrel 100 .

[0078] The housing 120 is primarily connected between the outer tub 100 and the drying module 21 of the laundry processing device 10, and is used to guide the air in the outer tub 100 into the drying module 21 through the air outlet 121. The shape of the housing 120 can be adjusted based on the relative position between the tub 110 and the drying module 21, and can be connected to the air outlet 113 of the tub 110 and the drying module 21.

[0079] In some embodiments: if the air outlet 113 is set at the bottom of the outer cylinder 100, the drying module 21 is set at the top of the outer cylinder 100, one end of the shell 120 is connected to the air outlet 113, and the other end is connected to the drying module 21, the 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 21.

[0080] In some embodiments, the directions such as above, below, top, and bottom mentioned in the embodiments of the present disclosure all refer to the positional relationship of the outer cylinder 100 in the working state.

[0081] 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 can be the lowest end of the entire cylinder 110, or it may not be the lowest end of the cylinder 110.

[0082] In some embodiments, when the axis of the cylinder 110 is vertical, the bottom surface 112b is disposed below the opening 112a. When the axis of the cylinder 110 is horizontal, both the bottom surface 112b and the opening 112a are disposed vertically. If the opening 112a is disposed in front of the cylinder 110, the bottom surface 112b is disposed in the rear of the cylinder 110. In the embodiments disclosed herein, the cylinder 110 is horizontally disposed as an example (the opening 112a is disposed in front of the cylinder 110, and the bottom surface 112b is disposed in the rear of the cylinder 110). The inner cylinder 11 is disposed in the accommodating chamber 112 and is coaxial with the cylinder 110, i.e., a certain gap is provided between the outer circumference of the inner cylinder 11 and the inner wall of the accommodating chamber 112.

[0083] At least part of the air outlet 113 is set on the bottom surface 112b. The air outlet 113 can be completely set on the bottom surface 112b, or part of the air outlet 113 can be set on the bottom surface 112b and part of the air outlet 113 can be set at other positions, so as to ensure that the air outlet 113 can connect the accommodating cavity 112 and the air outlet channel 121.

[0084] In the embodiment of the present disclosure, the lowest point of the air outlet 113 is close to or flush with the lowest point of the bottom surface 112 b , which means that the lowest point of the air outlet 113 is close to the lowest point of the bottom surface 112 b . When the return 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 return water can directly return 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 of the bottom surface 112b and the lowest point of the inner drum 11, with a certain height difference. When the return water flows back to the lowest point of the bottom surface 112b, the height of the lowest point of the bottom surface 112b is lower than the height of the lowest point of the inner drum 11, so that the return water can be discharged through the lowest point of the bottom surface 112b, which can avoid the return water from flowing into the inner drum 11 as much as possible, thereby reducing the risk of the return water wetting or contaminating the clothes, thereby improving the drying and cleaning effect of the clothes.

[0085] In some embodiments, it should be noted that the lowest point of the bottom surface 112b refers to the point at the bottom of the bottom surface 112b in the vertical direction. Similarly, the lowest point of the air outlet 113 is also the point at the bottom 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.

[0086] 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.

[0087] 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 .

[0088] 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 may be provided on both the bottom surface 112 b and the side surface 112 c .

[0089] The air outlet 113 is arranged on the bottom surface 112b and the side surface 112c at the same time. Compared with the air outlet 113 being arranged only 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 air flow can enter the air outlet channel 121 through the air outlet 113, which can speed up the air flow circulation speed in the clothing processing device 10, thereby reducing the drying time and improving the drying effect.

[0090] When water flows back into the cylinder 110 through the air outlet channel 121, since the air outlet 113 is arranged on both the bottom surface 112b and the side surface 112c, the opening area of ​​the air outlet 113 is larger. When the water flow can pass through the air outlet 113 with a larger opening area, the flow rate can be slowed down, so that the water can enter the bottom of the cylinder 110 at a slower flow rate, reducing the splashing of water in the cylinder 110, thereby reducing the risk of water entering the inner cylinder 11 to a certain extent.

[0091] In some embodiments, the opening 112a and the bottom surface 112b are substantially vertically arranged, and the side surface 112c is substantially annular in structure, with multiple positions of different heights on the same circle of the side surface 112c.

[0092] In some embodiments, the side surface 112c has a water receiving surface 112d, which is disposed at the lowest point of the side surface 112c, and the air outlet 113 extends to the water receiving surface 112d.

[0093] The water receiving surface 112d is set below the side surface 112c and is the lowest point on the entire 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. During 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, the water receiving surface 112d is also lower than the lowest point of the inner drum 11. When the water flow enters the accommodating chamber 112, it can be discharged to the outside of the cylinder 110 through the water receiving surface 112d, reducing the risk of water flowing into the inner drum 11, reducing the risk of clothes getting wet after drying, and improving the drying effect.

[0094] In some embodiments, 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.

[0095] Please refer to Figures 3 and 4. In some embodiments, the bottom surface 112b of the cylinder 110 has a mounting portion 114, and the air outlet 113 and the mounting portion 114 are staggered. In some embodiments, the mounting portion 114 is used to mount the inner cylinder 11, and the projection of the inner cylinder 11 on the bottom surface 112b coincides with the mounting portion 114.

[0096] The inner cylinder 11 is installed within the accommodating cavity 112 and is coaxial with the cylindrical body 110. That is, the radius of the inner cylinder 111 is smaller than that of the cylindrical body 110. The projection of the inner cylinder 111 on the bottom surface 112b is entirely located on the bottom surface 112b. The projection of the inner cylinder 11 on the bottom surface 112b coincides with the mounting portion 114, and the projection of the inner cylinder 11 on the bottom surface 112b can be considered to be the mounting portion 114. The air outlet 113 is offset from the mounting portion 114, indicating that the air outlet 113 is located outside the projection of the inner cylinder 11 on the bottom surface 112b. In other words, the air outlet 113 can be considered to be offset from the inner cylinder 11.

[0097] The air outlet 113 is staggered with the inner drum 11. When the backflow water flows back into the accommodating chamber 112, the staggered arrangement of the air outlet 113 and the inner drum 11 can further reduce the risk of the backflow water splashing into the inner drum 11, and can reduce the risk of the backflow water wetting or dirtying the clothes.

[0098] In some embodiments, the air outlet 113 is staggered with the inner tube 11 , which means that the entire air outlet 113 is staggered with the inner tube 11 , and no portion of the air outlet 113 overlaps with the inner tube 11 .

[0099] 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.

[0100] 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. 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.

[0101] The shape of the first connecting side 113a is adapted to the shape of the inner tube 11, and may be the same as the outer contour of the inner tube 11. Since the first connecting side 113a is the uppermost part 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 tube 11, so that the water flow always flows within the range before the outer contour of the inner tube 11, which can further reduce the risk of water splashing into the inner tube 11 and the risk of backflow water wetting or dirtying clothes.

[0102] In some embodiments, since the air outlet 113 and the inner tube 11 are staggered, there is a certain gap between the first connecting side 113a and the outer contour of the inner tube 11. Of course, the first connecting side 113a can also be infinitely close to the outer contour of the inner tube 11.

[0103] Referring to FIG. 5 and FIG. 6 , in some embodiments, a guide surface 121 a is provided in the air outlet channel 121 . The guide surface 121 a is connected to the first connecting side 113 a and matches the shape of the first connecting side 113 a .

[0104] The drainage surface 121a is disposed within the air outlet channel 121. The shape of the drainage surface 121a matches the shape of the first connection side 113a, indicating that the drainage surface 121a has the same shape as the first connection side 113a. Since the first connection side 113a is disposed above the air outlet 113, the drainage surface 121a is also disposed above the air outlet 113. When water flows from top to bottom, the drainage surface 121a can guide the water flow and direct the water flow toward the bottom of the water outlet 126, thereby preventing the water from splashing when entering the water outlet 126. This allows the water flow to smoothly enter the accommodating chamber from the water outlet 126, thereby reducing the risk of backflow water wetting or soiling clothing.

[0105] In some embodiments, a stop surface 121 b is provided in the air outlet channel 121 , and the stop surface 121 b is connected to the second connection side 113 b .

[0106] In some embodiments, the second connecting side 113b is set roughly vertically, and the stop surface 121b is also set roughly vertically. When the water flows from top to bottom, the stop surface 121b can play a certain flow-limiting role on the water flow, slowing down the flow of the water flow, so that the water flow can enter the accommodating cavity 112 from the air outlet 113 at a lower speed, and the water flow can smoothly enter the accommodating cavity 112 from the water outlet 126, thereby reducing the risk of backflow water wetting or dirtying clothes.

[0107] Please refer to 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, and together with the bottom plate 116 forms a accommodating cavity 112. 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 together with the bottom plate 116 forms an air outlet channel 121.

[0108] 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 forms a accommodating chamber 112. The outer shell 120 is connected to the bottom plate 116, and together with the bottom plate 116 forms an air outlet channel 121. Part of the structure of the bottom plate 116 can be used to form the air outlet channel 121, which can make the shape of the entire outer tube 100 more compact.

[0109] Please refer to Figures 6 and 7. In some embodiments, the housing 120 includes a rear panel 123 and multiple side panels 124. The multiple side panels 124 are respectively connected to different sides of the rear panel 123 and are connected to the bottom panel 116. The bottom panel 116, the rear panel 123 and the multiple side panels 124 together form an air outlet channel 121.

[0110] In some embodiments, the number of side panels 124 is the same as the number of sides of the rear panel 123. For example, if the rear panel 123 is a quadrilateral, then the rear panel 123 has four sides, and accordingly, four side panels 124 are also provided, with one side panel 124 connected to one side of the rear panel 123 and the barrel 110. Of course, the shape of the side panels 124 should be the same as the shape of the sides of the rear panel 123, so that the entire housing 120 can form a relatively regular structure.

[0111] In some embodiments, a side panel 124 is located at a lower position of the entire rear panel 123, and it can also be considered that the side panel 124 is provided at the end below the rear panel 123. For the convenience of description, the side panel 124 can be defined as a stop panel 128. The stop panel 128 is provided substantially vertically, and the stop surface 121b is provided on the stop panel 128. The direction of water flow is along the extension direction of the rear panel 123, and the air outlet 113 is provided on the bottom plate 116, so that the direction of water flow in the air outlet channel 121 is different from the direction of water flow into the accommodating chamber 112. The stop panel 128 is provided at the end of the rear panel 123, which can block the water flow in the direction of water flow, slow down the flow rate of the backflow water entering the accommodating chamber 112, and allow the water flow to smoothly enter the accommodating chamber 112 from the water outlet 126, thereby reducing the risk of the backflow water wetting or soiling the clothes.

[0112] In some embodiments, a guide plate 129 is provided in the air outlet channel 121 . The guide plate 129 is provided at the air outlet 113 , and at least a portion of the shape of the guide plate 129 matches the shape of the air outlet 113 .

[0113] 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 backflow water wetting or dirtying clothes.

[0114] In some embodiments, the guide surface 121 a is provided on the guide plate 129 . In addition, the guide plate 129 may not be provided. In some embodiments, the guide surface 121 a may be provided on a side plate 124 .

[0115] 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 invalid cavity between the guide plate 129 and the side plate 124 where no water flows. Although no water flows through, the contact area between the entire shell 120 and the bottom plate 116 can be increased, thereby improving the fixing effect of the shell 120.

[0116] In some embodiments, the outer tube 100 further includes an end cover 140 and a filter 130 disposed within the outlet tube belt 121 . An inspection port 122 is provided on one end of the outer shell 120 near 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.

[0117] 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.

[0118] The filter 130 is disposed within the outlet passage 121, i.e., in the path of the airflow within the outlet passage 121. It is primarily used to filter debris from the airflow. The filter 130 is disposed transversely within the outlet passage 121, filling the entire cross-section of the outlet passage 121 in the direction of the airflow. This allows all airflow through the outlet passage 121 to be filtered by the filter 130, preventing debris from entering the drying module 21. The filter 130 is rinsed after drying, and during this process, some water may flow back into the inner drum 11.

[0119] When the filter 130 is flushed, 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. 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 of the bottom surface 112b and the lowest point of the inner drum 11 (the lowest point of the bottom surface 112b is located below the lowest point of the inner drum 11). When the clean water flows back to the lowest point of the bottom surface 112b, since the lowest point of the bottom surface 112b is lower than the lowest point of the inner drum 11, the clean water can be directly discharged from the air outlet 113 to the outside of the outer drum 100, which can reduce the situation where the clean water flows into the inner drum 11, thereby reducing the clean water from wetting or contaminating the clothes, thereby improving the drying and cleaning effect of the clothes.

[0120] That is, the return water includes condensed water and clean water of the filter 130 .

[0121] The end cap 140 is provided at the inspection port 122 and is mainly used to seal the inspection port 122, thereby preventing external impurities from entering the air outlet passage 121 or the drying module 21 and affecting the operation of the drying module 21. In addition, it can also prevent water leakage during the flushing process of the filter 130.

[0122] In some embodiments, the inspection port 122 can be provided at one end of the filter 130. When the filter 130 is removed, the inspection port 122 is exposed, and one can reach into the air outlet passage 121, grasp one end of the filter 130, and directly pull the filter 130 out of the inspection port 122. Similarly, when installing the filter 130, the other end of the filter 130 is first extended through the inspection port 122 into the air outlet passage 121 until the filter 130 is completely installed in the air outlet passage 121. Providing the inspection port 122 at one end of the filter 130 eliminates the need to connect the filter 130 and the inspection port 122 during assembly and disassembly of the filter 130, allowing for direct assembly and disassembly. This reduces the amount of manipulation required to assemble and disassemble the filter 130, making the assembly and disassembly process quicker and easier, and can reduce the time required to assemble and disassemble the filter 130, thereby improving assembly and disassembly efficiency.

[0123] In some embodiments, the housing 120 includes a rear panel 123 and multiple side panels 124 , the multiple side panels 124 are respectively connected to different sides of the rear panel 123 , the rear panel 123 and the multiple side panels 124 form an air outlet channel 121 , and the inspection port 122 is set on the rear panel 123 .

[0124] In some embodiments, the side panels 124 connect the drum 110 and the rear panel 123. That is, the rear panel 123 and the drum 110 are disposed opposite each other, and the rear panel 123 is located at the rearmost portion of the entire laundry processing apparatus 10. Providing the access opening 122 on the rear panel 123 facilitates the removal and installation of the filter 130. Furthermore, the surface area of ​​the rear panel 123 is greater than that of any of the side panels 124. Providing the access opening 122 on the rear panel 123 allows for a sufficiently large opening to facilitate the removal and installation of the filter 130.

[0125] 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 set. The first end 132 is set close to the rear plate 123, and the second end 134 is set away from the rear plate 123. The inspection port 122 is set close to the first end 132.

[0126] 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.

[0127] The side panel 124 is connected to the cylinder 110, that is, the first end 132 is arranged close to the rear panel 123, and the second end 134 is arranged close to the cylinder 110. Of 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. During the process of removing 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 directly insert their fingers into the air outlet channel 121 to grasp the filter 130, which can further reduce the difficulty of removing the filter 130 and improve the convenience of removing the filter 130, thereby reducing the removal time of the filter 130 and improving the efficiency of disassembly and assembly of the filter 130.

[0128] Please refer to FIG. 8 . In some embodiments, a water flow channel 125 is defined in the housing 120 . The water flow channel 125 has a water outlet 126 communicating with the air outlet channel 121 . The inspection port 122 is disposed near the water outlet 126 .

[0129] After the laundry processing device 10 has dried the laundry, water can be discharged from the water outlet 126 to clean the filter 130. It should be noted that the water flow direction and the air flow direction are opposite to each other in order to clean and flush away the lint on the filter 130. For example, in the operating state, if the air flow direction is from bottom to top, the water flow direction should be from top to bottom, and the water outlet 126 should be located on the side of the filter 130 close to the drying module 21.

[0130] In some embodiments, 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 larger 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.

[0131] 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 near 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.

[0132] In some embodiments, the inspection port 122 is disposed below the water outlet 126 .

[0133] It should be noted that the inspection port 122 is located below the water outlet 126, which means that when the laundry treatment device 10 is in use or operating, the inspection port 122 is located below the water outlet 126. The inspection port 122 is located below the water outlet 126, and the inspection port 122 is located at the first end 132 of the filter 130, which means that the filter 130 is also located below the water outlet 126. The filter 130 is located below the water outlet 126, allowing water to flow toward the filter 130 under the action of its own gravity. The water pressure and its own gravity can flush away debris from the filter 130, thereby improving the flushing effect.

[0134] In some embodiments, the entire water flow channel 125 and the inspection port 122 are arranged on the same side of the housing 120, both arranged on this 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.

[0135] In some embodiments, the water flow channel 125 is tilted toward the filter 130 so that the water outlet 126 is disposed within 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 .

[0136] In some embodiments, the water flow channel 125 can be tilted relative to the housing 120 so that the water flow flowing out of the water outlet 126 can have a certain tilt 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.

[0137] In some embodiments, the filter 130 can be tilted relative to the outer shell 120, and the water flow channel 125 can also be tilted relative to the outer 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 outer shell 120 can be set according to actual conditions.

[0138] Since the water flow channel 125 is tilted compared to the outer shell 120, there is a step surface 127 below the water outlet 126 connected to the inspection port 122. In addition, the water flow channel 125 is tilted 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 interior of 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.

[0139] The above mainly describes the specific positions of the end cover 140 and the inspection port 122 on the shell 120, as well as the positional relationship between the inspection port 122, the filter screen 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.

[0140] Please refer to Figures 3 and 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. The cover plate 142 is detachably connected to the shell 120.

[0141] 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 from the inspection port 122 as much as possible.

[0142] As for the connection between the cover plate 142 and the rear plate 123 , they can be fixedly connected by screws or by snap-fitting, and the specific structure is not limited.

[0143] In some embodiments, when the cover plate 142 and the back 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 back plate 123. Screws, bolts or studs are passed through the first fixing hole 142a and the second fixing hole to fix the cover plate 142 and the back plate 123.

[0144] In addition, a disassembly hole 142b can be provided on the cover plate 142. When the cover plate 142 needs to be removed from the rear plate 123, a tool (such as a screwdriver, a rope, a pull ring, etc.) can be inserted into the disassembly hole 142b to remove the cover plate 123. The disassembly hole 142b is mainly pierced by a tool, and the diameter of the disassembly hole 142b can be set relatively large, and can be larger than the first fixing hole 142a.

[0145] 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 abuts against the side wall of the inspection opening 122 .

[0146] 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 a material such as silicone or rubber. The sealing end 143a will be deformed during the abutment process against the side wall of the inspection port 122, which can make the sealing end 143a and the side wall of the inspection port 122 in close contact, and the connecting end 143b is clamped between other positions of the inspection port 122. The connection through the clamping method can facilitate the assembly between the plug portion 143 and the inspection port 122.

[0147] During the assembly process, the connecting end 143b can be first engaged with the side wall of the inspection port 122, and then the entire plug portion 143 can be pushed into the interior of the inspection port 122. During the pushing process, the sealing portion 143h contacts the inner wall of the inspection port 122 and the stepped surface 127, causing deformation until the entire plug portion 143 is located within the air outlet channel 121. The cover plate 142 is then fixed to the housing 120, thereby installing the entire end cap 140 on the housing 120. This installation method only requires engaging the connecting end 143b with the side wall of the inspection port 122 first, and then fixing the cover plate 142 to the housing 120. The operation is simple and convenient.

[0148] 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 .

[0149] In some embodiments, the sealing end 143a is disposed near the water outlet 126, and the connecting end 143b is disposed away from the water outlet 126, that is, the sealing end 143a is disposed above the connecting end 143b. The connecting end 143b is primarily used to connect to the inspection port 122, and the sealing end 143a is primarily used to seal the gap between the inspection port 122 and the water outlet 126. The entire plug portion 143 can be made of an elastic material, such as silicone or rubber. The sealing end 143a deforms during the contact process with the side wall of the inspection port 122 and the stepped surface 127, enabling close contact between the sealing end 143a and the side wall of the inspection port 122, and between the sealing portion 143h and the stepped surface 127, thereby improving the sealing effect between the inspection port 122 and the water outlet 126.

[0150] In some embodiments, the thickness of the sealing end 143a is greater than the thickness of the connecting end 143b.

[0151] Since the water flow channel 125 is tilted inward 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.

[0152] 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 to 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.

[0153] In some embodiments, the plug portion 143 has an inclined avoidance surface 143 c , and the avoidance surface 143 c connects the sealing end 143 a and the connecting end 143 b .

[0154] Since the thickness of the connecting end 143b is less than that of the sealing end 143a, the sealing end 143a and the connecting end 143b can be connected by the avoidance surface 143c to ensure a smooth transition of the entire plug portion 143. In addition, by avoiding the inclined surface, a portion of the air outlet channel 121 can be avoided, leaving space below the plug portion 143 for the air outlet channel 121, facilitating airflow from below and reducing the impact of the plug portion 143 on the airflow to a certain extent.

[0155] 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.

[0156] 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 port 122 .

[0157] That is, the connecting end 143b has a slot 143e, and during installation, the side wall of the inspection opening 122 is engaged with the slot 143e, which can limit and fix the plug 143. At the same time, the flange 143d overlaps with the rear plate 123 at the inspection opening 122, covering the gap between the plug 143 and the side wall of the inspection opening 122, and also providing a certain sealing effect.

[0158] In some embodiments, at least the connecting end 143b has a flange 143d, which means that only the connecting end 143b has the flange 143d, or the connecting end 143b and one transition end 143f in some embodiments 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.

[0159] In some embodiments, the outer circumference of the plug portion 143 has a plurality of spaced-apart sealing portions 143 h (eg, sealing ribs). The sealing portions 143 h abut against the sidewall of the inspection port 122 to form an interference fit, thereby sealing the inspection port 122 .

[0160] The sealing portion 143h is annularly disposed on the outer circumference of the plug portion 143, and the sealing end 143a is protruding from the outer circumference of the plug portion 143 and is capable of abutting against the inner wall of the inspection port 122 to seal the inspection port 122. Multiple sealing portions 143h are sequentially disposed in a direction approaching the cover plate 142. Providing multiple sealing portions 143h can form a multi-stage seal for the inspection port 122, further improving the sealing effect.

[0161] As for the protruding heights of the multiple sealing portions 143h relative to the plug portion 143, they can be the same or different, and can 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.

[0162] In summary, in the outer cylinder 100 provided in the embodiment of the present disclosure, the lowest point of the air outlet 113 is close to or flush with the lowest point of the bottom surface 112 b , which means that the lowest point of the air outlet 113 is not higher than the lowest point of the bottom surface 112 b . When the return water 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 return 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 (the lowest point of the bottom surface 112b is located below the lowest point of the inner drum 11). When the clean water flows back to the lowest point of the bottom surface 112b, since the lowest point of the bottom surface 112b is lower than the lowest point of the inner drum 11, the clean water can be directly discharged from the air outlet 113 to the outside of the outer drum 100, 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 effect of clothes.

[0163] Please refer to Figure 7. Based on the same inventive concept, the embodiment of the present disclosure also provides a clothing processing device 10. The clothing processing device 10 provided by the embodiment of the present disclosure 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.

[0164] In the disclosed embodiment, the laundry processing device 10 includes an inner drum 11 and the outer drum 100 described above, and the inner drum 11 is disposed within the accommodating chamber 112. In some embodiments, the laundry processing device 10 may be a clothes dryer, a clothes dryer, or a washer-dryer. The laundry processing device 10 may be applicable to any type of laundry processing device 10, including but not limited to side-loading drum washing machines, top-loading drum washing machines, pulsator washing machines, agitator washing machines, mini washing machines, and the like.

[0165] In some embodiments, the clothing processing device 10 may include a drum 30 and the above-mentioned air outlet structure 100 or the above-mentioned drying module 21. The cylinder 110 and the inner drum 11 constitute the above-mentioned drum 30. The outer shell 120 is connected to the drum 30, which is actually the outer shell 120 connected to the cylinder 110. And the air outlet channel 121 is connected to the air outlet 113 of the drum 30 (the air outlet 113 of the cylinder 110). In some embodiments, the outer shell 120 and the drum 11 jointly form the air outlet channel 121 (actually, the outer shell 120 and the cylinder 110 jointly form the air outlet channel 121). In addition, the outer shell 120 can also form the air outlet channel 121 alone and be connected only to the drum 11 (cylinder 110).

[0166] Based on the same inventive concept, the disclosed embodiments further provide a drying module 20, which includes a drying body 21, a fan, and the aforementioned air outlet structure 100. The fan is in fluid communication with an air outlet passage 121. The fan can be disposed within or outside the air outlet passage 121, primarily for directing air within the air outlet passage 121 into the drying body 21, where it is dehumidified and heated.

[0167] The housing 110 is connected between the outer tub 100 and the drying module 21, and is used to guide the air in the outer tub 100 into the drying module 21 through the air outlet channel. During the drying process, a circulating airflow is formed between the inner tub 11 and the drying module 21, which serves the purpose of drying clothes.

[0168] Based on the same inventive concept, the embodiment of the present disclosure provides a control method for a laundry processing device 10, which is applied to the above-mentioned laundry processing device 10. As for the specific structure of the laundry processing device 10, it has been described in detail above and will not be repeated here. For the specific structure of the laundry processing device 10, please refer to the above description.

[0169] The clothing treatment device 10 further includes a filtering structure, such as the filter 130 described above. The filtering structure (filter 130) is used to filter the drying airflow during the drying phase of the clothing treatment device 10. The filtering structure (filter 130) is disposed within the air outlet channel 121, i.e., on the path of the airflow in the air outlet channel 121, and is primarily used to filter lint in the airflow. The filtering structure (filter 130) is transversely disposed within the air outlet channel, and is capable of filling the entire cross-section of the air outlet channel in the airflow direction, so that all airflow passing through the air outlet channel can be filtered by the filtering structure (filter 130), thereby preventing lint from entering the drying module 21.

[0170] The housing 100 is provided with a water flow channel 125, through which water enters to flush the filter structure (filter screen 130), thereby preventing hair debris from being blown into the desiccant in the drying module 21 during the drying cycle, thereby clogging the desiccant and affecting the drying effect. In some embodiments, the desiccant can be a material with hygroscopic properties, such as zeolite, modified / synthetic zeolite, molecular sieve, polymer desiccant, alkali metal aluminosilicate, lithium chloride, silica gel, modified silica gel, activated alumina, etc.

[0171] As shown in FIG10 , the control method of the laundry processing device 10 includes:

[0172] Step 301: Obtain a laundry processing mode set by a user, and determine a rinsing mode of the filter structure (filter 130) corresponding to the laundry processing mode according to the laundry processing mode;

[0173] In addition, the laundry processing mode may also be the acquired current processing mode of the laundry processing device.

[0174] Step 302 : flushing the filter structure (filter screen 130 ) according to the flushing mode of the filter structure (filter screen 130 ).

[0175] In this embodiment, a user-selected laundry processing mode is obtained, and the laundry processing modes include a washing mode, a drying mode, a washer-dryer mode, etc. After obtaining the user-selected laundry processing mode, a filter structure (filter 130) flushing mode corresponding to the user-set laundry processing mode is determined from among a plurality of pre-stored filter structure (filter 130) flushing modes.

[0176] In some embodiments, the laundry is processed according to the laundry processing mode selected by the user. Specifically, if the laundry processing mode selected by the user is a washing mode, the washing stage of the washing mode includes a main wash stage, a rinsing stage, and other processing stages. The main wash stage and the rinsing stage both include a water intake step, a washing step, a dehydration step, and a drainage step to achieve laundry washing.

[0177] If the clothing processing mode selected by the user is the drying mode, the processing stages entered include a drying stage and a cooling stage in sequence to dry the clothes; in some embodiments, the drying stage includes a dehydration step and a drying step, and in addition, a drainage step may be included before or after the drying step; the cooling stage may also include a drainage step.

[0178] If the clothing processing mode selected by the user is the washing and drying mode, the machine first enters the washing part (same as the aforementioned washing mode) and then enters the drying part (same as the aforementioned drying mode) to wash and dry the clothes.

[0179] It should be noted that the number of rinsing stages in the washing mode and the wash-drying mode can be greater than or equal to 1 time, and there is no specific limitation.

[0180] After determining the corresponding rinsing mode for the filter structure (filter 130) based on the acquired laundry processing mode, the filter structure (filter 130) is rinsed according to the determined rinsing mode. The filter structure (filter 130) can be rinsed after the corresponding laundry processing mode is completed, or it can be rinsed during the laundry processing process to prevent lint from clogging the filter structure (filter 130).

[0181] In the disclosed embodiment, the provision of a filter structure (filter 130) within the air outlet passage can minimize the entry of hair debris into the drying module, preventing hair debris from affecting the drying effect. Furthermore, the filter structure (filter 130) can be rinsed during or after the operation of the laundry processing mode to remove hair debris attached to the filter structure (filter 130), thereby minimizing hair debris from clogging the filter structure (filter 130) and improving the filter structure's (filter 130) ability to filter hair debris.

[0182] In some embodiments, different filter structure (filter 130) flushing modes can be set according to different clothing processing modes. The filter structure (filter 130) is flushed according to the filter structure (filter 130) flushing mode corresponding to the clothing processing mode selected by the user, so that the flushing method of the filter structure (filter 130) is more flexible and more adapted to the current clothing processing mode, thereby improving the flushing effect and further ensuring the dander filtering effect and drying effect.

[0183] In one or more embodiments of the present disclosure, the filter structure (filter screen 130) flushing mode includes at least one of the following: flushing duration, flushing times, and timing of flushing the filter structure (filter screen 130).

[0184] The flushing timing of the filter structure (filter 130) refers to the processing stage of the clothing processing mode at which the filter structure (filter 130) is flushed, that is, the flushing stage is in which processing stage of the clothing processing mode.

[0185] Different clothing processing modes correspond to different flushing modes of the filter structure (filter 130), that is, in different clothing processing modes, at least one of the flushing duration, flushing times and flushing timing of the filter structure (filter 130) is different.

[0186] In the embodiment of the present disclosure, under different clothing processing modes, the duration, number of times or processing stages of flushing the filter structure (filter 130) are different. The filter structure (filter 130) can be flushed according to the flushing mode of the filter structure (filter 130) corresponding to the clothing processing mode selected by the user, which can better adapt to the current clothing processing mode, thereby improving the flushing effect of the filter structure.

[0187] In one embodiment of the present disclosure, determining a rinsing mode of the filter structure (filter 130) corresponding to the laundry processing mode includes:

[0188] If the clothing processing mode is a drying mode or a washing and drying mode, the filtering structure (filter 130) flushing mode includes flushing the filtering structure (filter 130) after the drying stage of the drying mode or the washing and drying mode is completed.

[0189] In this embodiment, when the user selects a drying mode or a washing and drying mode as the laundry processing mode, the filter structure (filter 130) can be rinsed after the drying phase of the drying mode or the washing and drying mode. That is, a rinsing phase is added after the drying phase to rinse the filter structure (filter 130).

[0190] In one or more embodiments of the present disclosure, rinsing the filter structure (filter 130) after drying is completed can promptly rinse away the lint generated by the drying process, thereby minimizing the need to wait until the next time the clothes are processed for rinsing, which can make lint even more difficult to rinse away. If lint attached to the filter structure (filter 130) is not promptly cleaned, the longer the lint remains attached, the more difficult it will be to clean. In order to clean the lint, the rinsing time or number of rinses will be increased, and an increase in the rinsing time or number of rinses can easily shorten the service life of the filter structure (filter 130).

[0191] In some embodiments, if the filter structure (filter screen 130) is flushed before drying (e.g., during the washing phase), if a large amount of water is flushed, a water film may easily form on the filter structure (filter screen 130), causing the drying airflow to not circulate normally, which may cause a false alarm of the drying module being overheated. However, the present disclosure flushes the filter structure (filter screen 130) after drying, so that no water film is formed on the filter structure (filter screen 130) before drying. While ensuring the flushing effect of the filter structure (filter screen 130), the above-mentioned false alarm of the drying module being overheated can be avoided. Moreover, the coating on the filter structure (filter screen 130) will not be damaged before drying, which can improve the filtering effect of lint.

[0192] It should be noted that the filter structure (filter screen 130) can be rinsed after the drying stage and before the cooling stage; the filter structure (filter screen 130) can also be rinsed after the cooling stage so that the hair debris generated on the filter structure (filter screen 130) during the cooling stage can also be cleaned off.

[0193] The flushing time may be greater than or equal to 2 seconds. In addition, to avoid the risk of drain pipe clogging caused by excessive flushing volume and excessive hair debris in a single flush, in some embodiments, the flushing time is less than or equal to 20 seconds, and in other embodiments, the flushing time may be less than or equal to 10 seconds, or the flushing time may be less than or equal to 4 seconds, or the flushing time may be 3 seconds.

[0194] The flushing duration is the total flushing duration of the filter structure (filter screen 130) in the same flushing mode. If the filter structure (filter screen 130) is flushed only once in the same flushing mode, the single flushing duration is also the total flushing duration. If the filter structure (filter screen 130) is flushed multiple times in the same flushing mode, the total flushing duration is the sum of the multiple flushing durations.

[0195] It is worth noting that after drying, the filter structure (filter screen 130) is flushed, and 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 return 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 return water can directly return 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 of the bottom surface 112b and the lowest point of the inner drum 11, with a certain height difference. When the return water flows back to the lowest point of the bottom surface 112b, the height of the lowest point of the bottom surface 112b is lower than the height of the lowest point of the inner drum 11, so that the return water can be discharged through the lowest point of the bottom surface 112b, which can avoid the return water from flowing into the inner drum 11 as much as possible, thereby reducing the risk of the return water wetting or contaminating the clothes, thereby improving the drying and cleaning effect of the clothes.

[0196] In one embodiment of the present disclosure, determining the rinsing mode of the filter structure (filter 130) corresponding to the laundry processing mode further includes:

[0197] If the laundry processing mode is the wash-and-dry mode, the filter structure (filter 130) rinsing mode further includes rinsing the filter structure (filter 130) before the draining step of the washing portion of the wash-and-dry mode is completed. Flushing the filter structure (filter 130) before the draining step of the washing portion of the dry-and-dry mode is the rinsing timing of the rinsing mode.

[0198] In this embodiment, when the user selects the wash-and-dry mode for laundry treatment, in addition to rinsing the filter structure (filter 130) during or after the drying process, the filter structure (filter 130) can also be rinsed before each or part of the draining steps in the washing process. That is, in the wash-and-dry mode, a rinsing step is added during the washing process and during or after the drying process, achieving at least two rinses of the filter structure (filter 130).

[0199] In the embodiment of the present disclosure, in the wash-drying mode, the filter structure (filter 130) is rinsed in the washing part, and in the drying part or after the drying part. In the same clothing processing mode (wash-drying mode), the filter structure (filter 130) can be rinsed multiple times, and can be cleaned in small amounts multiple times. The risk of clogging the drain pipe due to excessive amount of hair washed away in a single time can be avoided as much as possible. The increase in the number of rinses can also improve the flushing effect of the filter structure (filter 130).

[0200] In one embodiment of the present disclosure, before the end of a drainage step in the washing portion of the wash-drying mode, the filter structure (filter screen 130) is rinsed for a time period of less than or equal to 20 seconds. In some embodiments, the rinsing time period may be less than or equal to 10 seconds, or less than or equal to 6 seconds. Alternatively, before the end of all or some drainage steps in the washing portion, the filter structure (filter screen 130) may be rinsed for a time period of less than or equal to 20 seconds, or less than or equal to 10 seconds, or less than or equal to 6 seconds.

[0201] In addition, in this embodiment, the filter structure (filter 130) is flushed in the washing part of the wash and dry mode, and the flushing time of the filter structure (filter 130) in the washing part is less than or equal to the preset time. For example, the preset time is 6s and the flushing time is 5s. That is, the filter structure (filter 130) is flushed for a short time in the washing part, so that it is not easy to produce a water film and will not cause damage to the coating on the filter structure (filter 130). The false alarm problem of overheating of the drying module can be avoided, and the filtering effect of hair debris can be improved.

[0202] In one embodiment of the present disclosure, determining the rinsing mode of the filter structure (filter 130) corresponding to the laundry processing mode includes:

[0203] If the laundry treatment mode is a washing mode, the filtration structure (filter screen 130 ) flushing mode includes flushing the filtration structure (filter screen 130 ) before each or part of the drainage steps of the washing mode are completed.

[0204] In this embodiment, when the user selects the washing mode as the laundry treatment mode, the filter structure (filter 130) is rinsed before the drainage step of the washing mode is completed. That is, in the washing mode, a separate rinsing step is added during the washing phase, or the rinsing of the filter structure (filter 130) is achieved by each or part of the water intake step.

[0205] In the embodiment of the present disclosure, in the washing mode, the filter structure (filter screen 130) is flushed during the washing stage, thereby improving the flushing effect of the filter structure (filter screen 130).

[0206] It should be noted that washing mode does not require drying, that is, lint on the filter structure (filter 130) will not affect the washing mode. However, the filter structure (filter 130) can still be rinsed in washing mode to ensure the cleanliness of the filter structure (filter 130), thereby ensuring the drying effect of the clothes the next time they are dried.

[0207] In one embodiment of the present disclosure, the filter structure (filter 130) can be flushed before a drainage step of the washing mode ends, and the flushing time of the filter structure (filter 130) is less than or equal to 20 seconds, or the flushing time is less than or equal to 10 seconds. In other embodiments, the flushing time can also be less than or equal to 6 seconds; or before all or part of the drainage steps end, the filter structure can be flushed for less than or equal to 20 seconds. In other embodiments, the flushing time can also be less than or equal to 10 seconds, or the flushing time can be less than or equal to 6 seconds.

[0208] In this embodiment, the filter structure (filter 130) is flushed during the washing stage of the washing mode. The flushing time of the filter structure (filter 130) during the washing stage is less than or equal to the preset time. For example, the preset time is 6 seconds and the flushing time is 5 seconds. That is, the filter structure (filter 130) is flushed for a short time during the washing stage, so that water film is not easily generated and the coating on the filter structure (filter 130) is not damaged. The false alarm problem of overheating of the drying module can be avoided, and the filtering effect of hair debris can be improved.

[0209] In one embodiment of the present disclosure, before the drainage step is completed, the filter structure (filter screen 130) is flushed, including:

[0210] The filtering structure (filter screen 130 ) is flushed before, during, and after each of the water intake step and / or the dehydration step, and before and during each of the water drainage steps.

[0211] In this embodiment, in the washing mode or the washing and drying mode, the filter structure (filter screen 130) is rinsed before, during, and after the water filling step and / or the spin step, and before and during the drainage step. By rinsing the filter structure (filter screen 130) before drainage, it is ensured that hair debris adhering to the filter structure (filter screen 130) is rinsed out of the drum and discharged directly, without adhering to the clothes being washed again.

[0212] In another embodiment of the present disclosure, in the washing mode or the washing and drying mode, flushing can also be performed before the end of the water intake step or the drainage step of the main washing stage and / or the rinsing stage, so as to improve the water utilization efficiency or prevent the clothes from adhering to the lint on the filter again.

[0213] In some embodiments, as shown in FIG11 , a method for controlling the laundry treatment apparatus 10 includes:

[0214] Step 401: Obtain the clothing processing mode selected by the user.

[0215] Step 402 , determine the clothing processing mode selected by the user; if the clothing processing mode is the drying mode, proceed to step 406 ; if the clothing processing mode is the washing and drying mode, proceed to step 403 ; if the clothing processing mode is the washing mode, proceed to step 411 .

[0216] Step 403, main wash.

[0217] Step 404, rinse.

[0218] Step 405: flush the filter structure (filter screen 130) for 6 seconds.

[0219] Step 406, dehydration.

[0220] Step 407, draining.

[0221] Step 408, drying.

[0222] Step 409, cooling.

[0223] Step 410: flush the filter structure (filter screen 130) for 3 seconds, and then end.

[0224] Step 411, main wash.

[0225] Step 412, rinse.

[0226] Step 413, flush the filter structure (filter screen 130) for 6 seconds;

[0227] Step 414, dehydration.

[0228] Step 415, drain, end.

[0229] In the disclosed embodiment, the filter structure (filter 130) is flushed according to the flushing mode of the filter structure (filter 130) corresponding to the clothing processing mode selected by the user, so that the flushing method of the filter structure (filter 130) is more flexible and more adapted to the current clothing processing mode, thereby improving the flushing effect and further ensuring the dander filtering effect and drying effect.

[0230] It should be noted that one or more embodiments of the present disclosure can not only reduce the residual hair debris on the filter structure (filter screen 130), but also reduce the total flushing time of the filter structure (filter screen 130). Because the filter structure (filter screen 130) is flushed for a long time during the washing stage, and in the scheme of not flushing during the drying stage, the washing water all goes through the filter structure (filter screen 130), the total flushing time, that is, the washing water intake time, is greater than the actual time required to flush the filter structure (filter screen 130). The total flushing time of the filter structure (filter screen 130) in the embodiment of the present disclosure is the time that actually flushes the filter structure (filter screen 130). By reducing the total flushing time of the filter structure (filter screen 130), the service life of the filter structure (filter screen 130) can be guaranteed.

[0231] In one embodiment of the present disclosure, if the laundry processing mode is a washing mode or a washing and drying mode, before flushing the filter structure (filter 130) according to the filter structure (filter 130) flushing mode, the method further includes:

[0232] issuing a prompt message indicating whether to rinse the filter structure (filter 130) in the wash mode or the wash portion of the wash-dry mode;

[0233] The step of flushing the filter structure (filter screen 130) according to the flushing mode of the filter structure (filter screen 130) includes:

[0234] After obtaining confirmation information for flushing the filter structure (filter 130) in the washing mode or the washing part of the wash-drying mode, the filter structure (filter 130) is flushed according to the corresponding filter structure (filter 130) flushing mode.

[0235] In this embodiment, if the user selects the washing mode, since there is no drying requirement in this washing mode, the filtration structure (filter 130) may not be rinsed separately in the washing mode to save washing time. Instead, this process may be incorporated into the water intake step. Alternatively, to ensure the cleanliness of the filtration structure (filter 130), the filtration structure (filter 130) may still be rinsed separately in the washing mode. If the user selects the washing and drying mode, the filtration structure (filter 130) may not be rinsed separately in the washing mode to save washing time. Instead, this process may be incorporated into the water intake step to save washing time.

[0236] Therefore, the user is provided with prompt information to confirm whether to rinse the filter structure (filter screen 130) in this washing mode or in the washing and drying mode. After obtaining the user's confirmation information, the filter structure (filter screen 130) is rinsed.

[0237] The disclosed embodiment can determine whether to flush the filter structure (filter 130) in the washing mode or the washing and drying mode according to the actual needs of the user, thereby improving the flexibility of flushing the filter structure (filter 130).

[0238] In one embodiment of the present disclosure, the positional relationship between the air outlet of the clothing treatment device 10 and the bottom surface 112b of the accommodating chamber 112 of the outer drum 100 may not be changed, that is, there is no need to allow the clean water to flow directly below the inner drum 11. Instead, through image recognition, weighing, or other methods, it is determined whether there are still clothes in the inner drum after drying, that is, whether the user has removed the clothes. After it is determined that the user has removed the dried clothes, the filter structure (filter 130) can be rinsed. At this time, since there are no clothes in the inner drum 11, the problem of the dried clothes getting wet will not occur. Alternatively, after changing the positional relationship between the air outlet 113 of the clothing treatment device 10100 and the bottom surface 112b of the accommodating chamber 112 of the outer drum 100, the rinsing of the filter structure (filter 130) can also be controlled by determining whether there are still clothes in the inner drum 11.

[0239] As a specific implementation of the control method for the above-mentioned laundry processing device 10, the disclosed embodiments provide a control device for the laundry processing device 10, wherein the laundry processing device 10 includes a filtering structure (filter 130) configured to filter a drying airflow during the drying phase of the laundry processing device 10. As shown in FIG12 , the control device 500 of the laundry processing device includes an acquisition module 501, a determination module 502, and a control module 503.

[0240] In some embodiments, the acquisition module 501 is used to acquire the clothing processing mode set by the user;

[0241] A determination module 502 is configured to determine a rinsing mode of the filter structure (filter 130) corresponding to the laundry processing mode;

[0242] The control module 503 is configured to flush the filter structure (filter screen 130 ) according to the flushing mode of the filter structure (filter screen 130 ).

[0243] In this embodiment, a user-selected laundry treatment mode is obtained, including washing mode, drying mode, and washer-drying mode. After obtaining the user-selected laundry treatment mode, a filter structure (filter 130) flushing mode corresponding to the user-selected laundry treatment mode is determined from among multiple pre-stored filter structure (filter 130) flushing modes. Furthermore, the laundry is treated according to the user-selected laundry treatment mode, and the filter structure (filter 130) is flushed according to the determined filter structure (filter 130) flushing mode.

[0244] In the embodiment of the present disclosure, the filter structure (filter 130) can prevent hair debris from entering the drying module, preventing hair debris from affecting the drying effect, and can also be rinsed to prevent hair debris from clogging the filter structure (filter 130), thereby improving the filtering effect of the filter structure (filter 130) on hair debris.
