[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following is for reference. Figures 1-29 Description of a clothing processing device 100 according to an embodiment of the present invention.

[0027] like Figures 1-6As shown, the clothing processing device 100 according to an embodiment of the present utility model includes an outer cylinder assembly 10 and an inner cylinder (not shown in the figure). The outer cylinder assembly 10 includes an outer cylinder 11 and a heat exchange plate 12. The heat exchange plate 12 is disposed inside the outer cylinder 11, and a water passage cavity 101 is defined between the heat exchange plate 12 and the outer cylinder 11. The inner cylinder is rotatably disposed inside the outer cylinder 11.

[0028] like Figure 7 As shown, the water passage cavity 101 is located between the inner cylinder and the outer cylinder 11. The water passage cavity 101 has a water inlet 102 for water inlet and / or water outlet. The water passage cavity 101 also has an overflow outlet 1012, which is higher than the water inlet 102.

[0029] When water enters the water passage cavity 101 through the water inlet 102, that is, at this time the water inlet 102 is used as the water inlet 1011. Water enters the water passage cavity 101 through the water inlet 102 and the water flow will naturally flow upward. When the water level in the water passage cavity 101 rises to the overflow outlet 1012, the water overflows from the overflow outlet 1012. In this way, water is continuously introduced into the water passage cavity 101, so that the water in the water passage cavity 101 can fully exchange heat with the heat exchange plate 12.

[0030] Specifically, clothes can be placed in the inner drum. When the clothes handling device 100 executes the drying program, the inner drum rotates inside the outer drum 11, which can cause the clothes to tumble. At the same time, hot air can be introduced into the outer drum 11 to dry the clothes in the inner drum.

[0031] During the drying process, cooler water can be introduced into the water passage 101 through the water inlet 101. After entering the water passage 101, the cooler water will naturally flow upward. Specifically, the cooler water that just enters the water passage 101 is at the bottom, while the cooler water that has undergone heat exchange in the water passage 101 rises. When the water level in the water passage 101 rises to the overflow outlet 1012, the cooler water overflows from the overflow outlet 1012 first. In this way, cooler water is continuously introduced into the water passage 101, so that the water in the water passage 101 can fully exchange heat with the heat exchange plate 12, thereby reducing the temperature of the heat exchange plate 12. The heat exchange plate 12 can condense the hot air in the outer drum 11, causing the water vapor in the hot air to condense into liquid water and be discharged from the outer drum 11, thereby quickly drying the clothes in the inner drum.

[0032] According to the clothing processing device 100 of this utility model embodiment, by setting the overflow port 1012 higher than the water inlet 102, when water enters the water passage chamber 101 through the water inlet 102, the water entering the water passage chamber 101 can flow from bottom to top. In this way, the water with higher temperature overflows from the overflow port 1012 first, and the water with lower temperature can fully exchange heat with the heat exchange plate 12 during the process of flowing from bottom to top, thereby improving the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11, and thus improving the drying efficiency and drying effect of the clothing processing device 100.

[0033] It should be noted that the water inlet 102 can be selected to either fill or drain water when the clothing handling device 100 is in different working states.

[0034] For example, when the clothes handling device 100 is in the drying state, the water outlet 102 is the water inlet 1011 of the water passage chamber 101; when the clothes handling device 100 is in the draining state, the water outlet 102 is the drain outlet of the water passage chamber 101. In other words, the clothes handling device 100 here is a washer-dryer combo.

[0035] When the garment handling device 100 executes the washing program, the inner drum rotates inside the outer drum 11, which can carry the clothes to a certain height. When it exceeds a certain height, the clothes can fall freely under the action of gravity, thereby generating an impact force on the clothes and achieving the washing of the clothes.

[0036] When the clothes handling device 100 executes the drying program, hot air can be introduced into the outer drum 11 to dry the clothes in the inner drum. During the drying process, the water inlet 102 can be used as a water inlet 1011, through which cool water can be introduced into the water passage chamber 101. The water exchanges heat with the heat exchange plate 12, which can lower the temperature of the heat exchange plate 12. The heat exchange plate 12 can condense the hot air in the outer drum 11, causing the water vapor in the hot air to condense into liquid water and be discharged from the outer drum 11, thereby quickly drying the clothes in the inner drum.

[0037] When the water level in the water passage 101 rises to the overflow port 1012, the higher temperature water overflows from the overflow port 1012 first, and the lower temperature water is continuously introduced into the water passage 101, so that the heat exchange between the water in the water passage 101 and the heat exchange plate 12, and between the heat exchange plate 12 and the hot air in the outer cylinder 11 is more complete.

[0038] After the clothes handling device 100 finishes drying the clothes, the water outlet 102 can be used as a drain outlet so that the water in the water passage 101 can be discharged from the outer drum 11 through the water outlet 102.

[0039] In the above technical solution, the water inlet 102 can switch to different functions according to the actual use status. That is, the water inlet 102 can be used as an inlet 1011 when it is necessary to supply water to the water passage cavity 101, and as a drain outlet when it is necessary to drain the water in the water passage cavity 101. This avoids the growth of bacteria in the water passage cavity 101 due to residual water. The two-in-one hole helps to reduce the number of openings on the outer cylinder 11, simplify the structure of the outer cylinder 11, and ensure the structural strength of the outer cylinder 11.

[0040] like Figure 6 and Figure 7As shown, according to some embodiments of the present invention, when the clothing processing device 100 is in a dry state, the water inlet 102 is lower than the middle part of the outer cylinder 11 in the vertical direction, and the overflow outlet 1012 is higher than the middle part of the outer cylinder 11 in the vertical direction.

[0041] In the above technical solution, by setting the overflow port 1012 higher than the middle of the outer cylinder 11 in the vertical direction, the water capacity and distribution area of ​​the water passage cavity 101 can be increased. This can increase the contact area between the water in the water passage cavity 101 and the heat exchange plate 12, prolong the heat exchange time between the water in the water passage cavity 101 and the heat exchange plate 12, thereby improving the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11, and thus greatly improving the drying efficiency and drying effect of the clothes handling device 100.

[0042] like Figure 6 and Figure 8 As shown, according to some embodiments of the present invention, the axial direction of the outer cylinder assembly 10 is along the horizontal direction (e.g., Figure 6 and Figure 8 (As shown in the front-to-back direction) it extends or is inclined relative to the horizontal direction. The outer cylinder 11 includes an end wall 111 and a surrounding wall 112, the axial direction of the surrounding wall 112 being the axial direction of the outer cylinder assembly 10. The surrounding wall 112 surrounds the end wall 111, one end of the surrounding wall 112 is connected to the end wall 111, and the middle part of the end wall 111 has a shaft hole 11101, the shaft hole 11101 for the inner cylinder's rotating shaft to pass through.

[0043] Specifically, the garment handling device 100 also includes a drive device (not shown in the figure). The drive device is connected to one end of a rotating shaft, and the other end of the rotating shaft is connected to the inner drum. The rotating shaft can be rotatably supported on the end wall 111 by bearings. When the drive device is working, it can drive the inner drum to rotate inside the outer drum 11 through the rotating shaft, so that the garments can tumble inside the inner drum.

[0044] A water passage cavity 101 is defined between the heat exchange plate 12 and the end wall 111. That is, the heat exchange plate 12 is located on the side of the end wall 111 facing the inner drum, and the water passage cavity 101 is defined between the heat exchange plate 12 and the side of the end wall 111 facing the inner drum. By placing the heat exchange plate 12 on the side of the end wall 111 facing the inner drum, it does not occupy the circumferential space inside the outer drum 11, thus not changing the front dimensions of the clothing handling device 100.

[0045] like Figure 7 As shown, the water outlet 102 is lower than the shaft hole 11101, and the overflow outlet 1012 is higher than the shaft hole 11101.

[0046] For example, the vertical distance between the water inlet 102 and the shaft hole 11101 can be 1 / 2, 2 / 3, 3 / 4, etc., of the radius of the outer cylinder 11. The vertical distance between the overflow outlet 1012 and the shaft hole 11101 can also be 1 / 2, 2 / 3, 3 / 4, etc., of the radius of the outer cylinder 11.

[0047] In the above technical solution, by limiting the water inlet 102 to be lower than the shaft hole 11101 and the overflow outlet 1012 to be higher than the shaft hole 11101, the highest water level in the water passage 101 can exceed the shaft hole 11101. This increases the water capacity of the water passage 101, increases the contact area between the water in the water passage 101 and the heat exchange plate 12, and prolongs the heat exchange time between the water in the water passage 101 and the heat exchange plate 12. This improves the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11, thereby significantly improving the drying efficiency and drying effect of the clothes handling device 100.

[0048] In some embodiments, in a plane perpendicular to the axial direction of the outer cylinder assembly 10, the projected area of ​​the water passage cavity 101 in the plane is S1, and the projected area of ​​the end wall 111 in the plane is S, and the ratio of S1 to S is less than or equal to 0.9. For example, the ratio of S1 to S can be 0.1, 0.3, 0.5, 0.7, 0.9, etc.

[0049] This configuration ensures the connection area between the end wall 111 and the heat exchange plate 12, thereby guaranteeing the reliability of the connection between the outer cylinder 11 and the heat exchange plate 12. On the other hand, it improves the sealing performance of the connection between the end wall 111 and the heat exchange plate 12, thereby preventing water leakage in the water passage 101 and ensuring the heat exchange effect of the heat exchange plate 12.

[0050] like Figures 8-10 As shown, in some embodiments, the heat exchange plate 12 has a clearance hole 1201 in the middle, the clearance hole 1201 corresponds to the shaft hole 11101, and the water passage cavity 101 is an annular cavity surrounding the clearance hole 1201.

[0051] Setting the water passage cavity 101 as an annular cavity surrounding the avoidance hole 1201 can increase the distribution area of ​​the water passage cavity 101, which is beneficial to increase the contact area between the water in the water passage cavity 101 and the heat exchange plate 12, and prolong the heat exchange time between the water in the water passage cavity 101 and the heat exchange plate 12. This can improve the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11, thereby significantly improving the drying efficiency and drying effect of the clothes handling device 100.

[0052] like Figures 8-10As shown, in some embodiments, the outer cylinder assembly 10 further includes a first seal 141 and a second seal 142. The first seal 141 and the second seal 142 are both disposed between the end wall 111 and the heat exchange plate 12. The second seal 142 surrounds the outside of the clearance hole 1201, and the first seal 141 surrounds the outside of the second seal 142. The water passage cavity 101 is located between the first seal 141 and the second seal 142.

[0053] Therefore, by setting the first sealing element 141 and the second sealing element 142, the gap between the end wall 111 of the outer cylinder 11 and the heat exchange plate 12 can be sealed, ensuring the sealing of the water passage cavity 101 and preventing water leakage in the water passage cavity 101.

[0054] In some examples, the end wall 111 has a first mounting groove 11102 on the side facing the heat exchange plate 12, and a first seal 141 is disposed in the first mounting groove 11102. The heat exchange plate 12 has a first stop protrusion 1202 on the side facing the end wall 111, and the first stop protrusion 1202 stops the first seal 141.

[0055] Therefore, by providing a first stop protrusion 1202 on the side of the heat exchange plate 12 facing the end wall 111, the first stop protrusion 1202 presses against the first sealing member 141, thereby ensuring the sealing between the end wall 111 of the outer cylinder 11 and the heat exchange plate 12, further ensuring the sealing of the water passage cavity 101, and preventing water leakage in the water passage cavity 101.

[0056] In some examples, the end wall 111 has a second mounting groove 11103 on the side facing the heat exchange plate 12, and the second seal 142 is disposed in the second mounting groove 11103. The heat exchange plate 12 has a second stop protrusion 1203 on the side facing the end wall 111, and the second stop protrusion 1203 stops the second seal 142.

[0057] Therefore, by providing a second stop protrusion 1203 on the side of the heat exchange plate 12 facing the end wall 111, the second stop protrusion 1203 presses against the second sealing member 142, thereby ensuring the sealing between the end wall 111 of the outer cylinder 11 and the heat exchange plate 12, further ensuring the sealing of the water passage cavity 101, and preventing water leakage in the water passage cavity 101.

[0058] like Figure 2 , Figures 11-12 As shown, in some examples, the heat exchange plate 12 is fixed to the end wall 111 by a plurality of first fasteners 151, which are located on the outside of the first seal 141 and arranged circumferentially around the first seal 141. The heat exchange plate 12 is fixed to the end wall 111 by a plurality of second fasteners 152, which are located between the clearance hole 1201 and the second seal 142 and arranged circumferentially around the clearance hole 1201.

[0059] In the above technical solution, the use of multiple first fasteners 151 and multiple second fasteners 152 can improve the connection reliability between the end wall 111 of the outer cylinder 11 and the heat exchange plate 12, thereby ensuring the sealing between the end wall 111 of the outer cylinder 11 and the heat exchange plate 12, further ensuring the sealing of the water passage cavity 101, and preventing water leakage in the water passage cavity 101.

[0060] like Figure 3 As shown, in some embodiments, the end wall 111 has a positioning part, and the heat exchange plate 12 has a positioning mating part that cooperates with the positioning part. This arrangement allows for pre-positioning before connecting the end wall 111 and the heat exchange plate 12, facilitating subsequent connection of the end wall 111 and the heat exchange plate 12, thereby improving the production efficiency of the garment processing device 100.

[0061] In some examples, the positioning part is a positioning protrusion 11141, and the positioning mating part is a positioning notch 1204 provided on the edge of the clearance hole 1201. The structure is simple and easy to form.

[0062] like Figures 8-12 As shown, in some embodiments, the end wall 111 includes a first connecting wall 1111, a second connecting wall 1114, and a transition wall. In the radial direction of the end wall 111, the first connecting wall 1111 is located outside the second connecting wall 1114, and the transition wall is located between the first connecting wall 1111 and the second connecting wall 1114.

[0063] like Figure 19 and Figure 20 As shown, the heat exchange plate 12 includes a first mating wall 1251, a second mating wall 1252 and a heat exchange wall. In the radial direction of the heat exchange plate 12, the first mating wall 1251 is located outside the second mating wall 1252, and the heat exchange wall is located between the first mating wall 1251 and the second mating wall 1252.

[0064] The first mating wall 1251 is connected to the first connecting wall 1111, the second mating wall 1252 is connected to the second connecting wall 1114, and the water passage cavity 101 is located between the transition wall and the heat exchange wall.

[0065] Specifically, the first connecting wall 1111 is provided with a plurality of first connecting holes 11111, which are arranged at intervals along the extending direction of the first connecting wall 1111. The first mating wall 1251 is provided with a plurality of first mating holes 1206, which are also arranged at intervals along the extending direction of the first mating wall 1251. The positions of the plurality of first mating holes 1206 and the plurality of first connecting holes 11111 correspond one-to-one. The first connecting wall 1111 and the first mating wall 1251 are connected by a plurality of first fasteners 151, which pass through the corresponding first connecting holes 11111 and first mating holes 1206.

[0066] The second connecting wall 1114 is provided with a plurality of second connecting holes 11142, which are arranged at intervals in the extending direction of the second connecting wall 1114. The second mating wall 1252 is provided with a plurality of second mating holes 1207, which are also arranged at intervals in the extending direction of the second mating wall 1252. The positions of the plurality of second mating holes 1207 and the plurality of second connecting holes 11142 correspond one-to-one. The second connecting wall 1114 and the second mating wall 1252 are connected by a plurality of second fasteners 152, which pass through the corresponding second connecting holes 11142 and second mating holes 1207.

[0067] In the above technical solution, by connecting the first connecting wall 1111 and the first mating wall 1251 together, and connecting the second connecting wall 1114 and the second mating wall 1252 together, the sealing of the water passage cavity 101 can be guaranteed, water leakage in the water passage cavity 101 can be avoided, and the heat exchange effect of the heat exchange plate 12 can be guaranteed.

[0068] In some examples, the planes containing the first connecting wall 1111, the second connecting wall 1114, the first mating wall 1251, and the second mating wall 1252 are perpendicular to the axial direction of the outer cylinder 11. This arrangement facilitates the connection of the first connecting wall 1111 and the first mating wall 1251, as well as the connection of the second connecting wall 1114 and the second mating wall 1252.

[0069] like Figures 8-10 As shown, in some examples, the outer cylinder 11 has a cylinder opening, and the transition wall includes a first transition wall 1112, which extends axially away from the cylinder opening along the outer cylinder 11 to form a water-passing recess 11120 on the side of the first transition wall 1112 facing the cylinder opening.

[0070] like Figure 19 and Figure 20 As shown, the heat exchange wall includes a first heat exchange wall 124, which extends radially from the outside to the inside of the end wall 111 towards the direction of the cylinder opening.

[0071] The first heat exchange wall 124 and the water passage recess 11120 are arranged axially opposite to each other in the outer cylinder 11 to define a part of the water passage cavity 101.

[0072] In the above technical solution, by defining the water passage recess 11120 by the first transition wall 1112, a part of the water passage cavity 101 can be defined by the first heat exchange wall 124 and the water passage recess 11120, and the water capacity of the water passage cavity 101 can be increased, thereby accelerating the condensation efficiency of the heat exchange plate 12 on the hot air inside the outer cylinder 11.

[0073] like Figures 8-10 As shown, in some specific examples, the transition wall also includes a second transition wall 1113, which is located radially between the first transition wall 1112 and the second connecting wall 1114.

[0074] like Figure 19 and Figure 20 As shown, the heat exchange wall also includes a second heat exchange wall 121, which is located between the first heat exchange wall 124 and the second mating wall 1252 in the radial direction of the heat exchange plate 12.

[0075] The second transition wall 1113 and the second heat exchange wall 121 extend radially from the outside to the inside of the end wall 111 towards the cylinder opening, and the inclination angles are different. The first transition wall 1112 and the second heat exchange wall 121 are arranged opposite each other in the axial direction of the outer cylinder 11, and a portion of the water passage cavity 101 is defined between them.

[0076] In the above technical solution, by extending the second transition wall 1113 and the second heat exchange wall 121 in a radial direction from the outside to the inside towards the cylinder opening, and with different inclination angles, a portion of the water passage cavity 101 can be defined by the second transition wall 1113 and the second heat exchange wall 121, and the water capacity of the water passage cavity 101 can be increased, further accelerating the condensation efficiency of the heat exchange plate 12 on the hot air inside the outer cylinder 11.

[0077] like Figure 19 and Figure 20 As shown, the outer cylinder 11 has a cylinder opening, and the middle part of the heat exchange plate 12 extends along the axial direction of the outer cylinder 11 towards the cylinder opening to form a flow guiding protrusion on the side of the heat exchange plate 12 facing the cylinder opening, and a clearance groove 1208 is formed on the side of the heat exchange plate 12 facing the end wall 111 to avoid the end wall 111.

[0078] The heat exchange wall is at least a portion of the peripheral wall of the clearance groove 1208, and the second connecting wall 1114 is at least a portion of the bottom wall of the clearance groove 1208.

[0079] Therefore, by forming guide protrusions on the heat exchange plate 12, the flow direction of water can be changed during the washing process, which helps to improve the washing effect. During the drying process, the flow direction of hot air can be changed, which helps to improve the drying effect. Furthermore, the avoidance grooves 1208 formed on the heat exchange plate 12 can avoid the structure of the end wall 111. In addition, this arrangement of the heat exchange plate 12 can also improve its structural strength, thereby enhancing the reliability of the clothing handling device 100.

[0080] like Figure 7 , Figure 11 and Figure 12 As shown, in some examples, the outer cylinder assembly 10 also has an overflow channel 103, which is connected to the overflow outlet 1012.

[0081] Specifically, when the clothing processing device 100 is in the drying state, the cooler water enters the water passage chamber 101 from the water inlet 102 and the water will flow upward naturally. When the water level in the water passage chamber 101 rises to the overflow outlet 1012, the warmer water flows out of the water passage chamber 101 from the overflow outlet 1012 and is guided to a specific area through the overflow channel 103.

[0082] Therefore, by setting the overflow channel 103, the highest water level in the water passage 101 can be controlled, avoiding the pressure increase in the water passage 101 due to excessive water accumulation, reducing the probability of damage to the outer cylinder assembly 10, and ensuring that the clothing handling device 100 can work normally.

[0083] In some specific examples, an overflow channel 103 is defined between the heat exchange plate 12 and the end wall 111.

[0084] Therefore, by using the heat exchange plate 12 and the end wall 111 to define the overflow channel 103, on the one hand, it is convenient to process channels in the heat exchange plate 12 and / or the end wall 111, so that the parameters of the overflow channel 103 can be precisely controlled. On the other hand, the water in the overflow channel 103 can contact the heat exchange plate 12, so that the water flowing out of the overflow port 1012 of the water passage 101 can continue to exchange heat with the heat exchange plate 12, thereby further improving the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11, and greatly improving the drying efficiency and drying effect of the clothes handling device 100.

[0085] like Figure 11As shown, in some specific examples, the overflow channel 103 includes a first extension 1031 and a second extension 1032. The first extension 1031 is located outside the water passage cavity 101 and extends circumferentially along the water passage cavity 101. One end of the second extension 1032 is connected to the overflow port 1012 of the water passage cavity 101, and the other end of the second extension 1032 is connected to the first extension 1031.

[0086] In the above technical solution, by setting the overflow channel 103 to include a first extension section 1031 and a second extension section 1032, and placing the overflow channel 103 in the outer area of ​​the water passage cavity 101, the length of the overflow channel 103 can be extended, the flow time of water in the overflow channel 103 can be extended, and the water can fully exchange heat with the heat exchange plate 12, thereby further improving the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11, and thus improving the drying efficiency and drying effect of the clothes handling device 100.

[0087] In some specific examples, the first extension 1031 is an arc-shaped segment extending circumferentially along the water passage 101, and the second extension 1032 is a straight segment extending radially along the heat exchange plate 12.

[0088] This configuration extends the length of the overflow channel 103, allowing the water to fully exchange heat with the heat exchange plate 12, thereby further enhancing the condensation effect of the heat exchange plate 12 on the hot air inside the outer cylinder 11, and thus improving the drying efficiency and drying effect of the clothes handling device 100.

[0089] like Figure 11 As shown, in some optional embodiments, the number of overflow channels 103 and overflow outlets 1012 of water passage 101 is one. The overflow channel 103 is located on one side of the centerline extending vertically along the end wall 111.

[0090] like Figure 12 As shown, in some alternative embodiments, the number of overflow channels 103 and overflow ports 1012 of water passage 101 is two. The two overflow channels 103 and the two overflow ports 1012 of water passage 101 are connected in a one-to-one correspondence. The two overflow channels 103 are located on both sides of the center line extending in the vertical direction of the end wall 111, and the two overflow channels 103 are symmetrically arranged about the center line extending in the vertical direction of the end wall 111.

[0091] In the above technical solution, by setting two overflow channels 103 and symmetrically arranging the two overflow channels 103 about the center line extending in the vertical direction about the end wall 111, on the one hand, the distribution area of ​​the overflow channels 103 can be increased, and the condensation efficiency of the heat exchange plate 12 on the hot air in the outer cylinder 11 can be accelerated. On the other hand, the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11 can be more uniform, thereby further improving the drying efficiency and drying effect of the clothes handling device 100.

[0092] like Figures 11-14 As shown, in some embodiments, the enclosure 112 has a drainage cavity 1121 at the lower part, and the drainage cavity 1121 and the overflow channel 103 are connected by a water outlet channel 104, which is at least partially located on the end wall 111.

[0093] For example, a portion of the enclosure 112 is recessed downwards to form a drainage groove 1122 at the lower part of the enclosure 112, the drainage groove 1122 defining a drainage chamber 1121. The outer cylinder 11 may be equipped with a drainage pump (not shown in the figure), which can be used to drain water from the drainage chamber 1121.

[0094] Specifically, when the garment handling device 100 is in the washing state, the outer drum 11 can be used to hold water. After the washing is finished, the drain pump can drain the washing water in the outer drum 11 until the washing water in the drain chamber 1121 is completely drained.

[0095] When the clothes handling device 100 is in the drying state, the cooler water enters the water passage chamber 101 from the water inlet 102 and flows upward naturally. When the water level in the water passage chamber 101 rises to the overflow outlet 1012, the water flows out of the water passage chamber 101 from the overflow outlet 1012 and flows into the drain chamber 1121 through the overflow channel 103 and the outlet channel 104 in sequence. Finally, the water in the drain chamber 1121 is discharged by the drain pump.

[0096] In the above technical solution, by setting a drainage chamber 1121 at the lower part of the enclosure 112, the drainage chamber 1121 can store water overflowing from the water passage chamber 101, facilitating the centralized discharge of water overflowing from the water passage chamber 101. This allows for a continuous supply of water to the water passage chamber 101, improving the condensation effect of the heat exchange plate 12 on the hot air inside the outer cylinder 11, and enhancing the drying efficiency and effect of the clothes handling device 100. Furthermore, since the drainage chamber 1121 is located at the lower part of the enclosure 112, it facilitates the complete drainage of water inside the outer cylinder 11, reducing water residue.

[0097] The following is in conjunction with the appendix Figures 1-29 Describes a garment processing apparatus 100 according to some embodiments of the present invention.

[0098] like Figures 1-3As shown, a garment handling device 100 according to some embodiments of the present invention includes an outer cylinder assembly 10 and an inner cylinder (not shown in the figure). The outer cylinder assembly 10 includes an outer cylinder 11 and a heat exchange plate 12, the heat exchange plate 12 being disposed inside the outer cylinder 11.

[0099] like Figure 6 As shown, the outer cylinder 11 extends along the front-to-back direction or is inclined relative to the front-to-back direction. The outer cylinder 11 includes an end wall 111 and a surrounding wall 112. The surrounding wall 112 is arranged around the end wall 111. The rear end of the surrounding wall 112 is connected to the end wall 111 and the front end of the surrounding wall 112 defines the cylinder outlet.

[0100] In some embodiments, the end wall 111 has a shaft hole 11101 in the middle and the inner tube has a clearance hole 1201 in the middle, the clearance hole 1201 being positioned corresponding to the shaft hole 11101. The garment handling device 100 also includes a driving device, which is connected to the inner tube via a rotating shaft to drive the inner tube to rotate within the outer tube 11, the rotating shaft passing through the shaft hole 11101.

[0101] The clothing handling device 100 also includes a drying module (not shown in the figure), which generates hot air and introduces the hot air into the outer drum 11 to dry the clothes in the inner drum.

[0102] like Figures 6-9 As shown, in some embodiments, the heat exchange plate 12 and the end wall 111 of the outer cylinder 11 define a water passage cavity 101. The water passage cavity 101 has a water inlet 102 and an overflow outlet 1012. The water inlet 102 is located on the end wall 111 of the outer cylinder 11, below the shaft hole 11101, and the overflow outlet 1012 is located above the shaft hole 11101.

[0103] When water enters the water passage 101, the water passage 102 can be used as the water inlet 1011. When the water level in the water passage 101 rises to the overflow outlet 1012, the water in the water passage 101 can overflow from the overflow outlet 1012. When the water passage 101 needs to be drained, the water passage 102 can be used as the drain outlet.

[0104] In some examples, a portion of the end wall 111 is recessed in a direction away from the cylinder opening to form a water-passing recess 11120 on the side surface of the end wall 111 facing the cylinder opening. The water-passing recess 11120 extends circumferentially along the shaft hole 11101. The heat exchange plate 12 covers the water-passing recess 11120 to define a portion of the water-passing cavity 101 with the water-passing recess 11120.

[0105] The water-passing recess 11120 has a platform portion 11121 at a lower position. The water-passing cavity 101 is located above the platform portion 11121. The water-passing outlet 102 is provided in the water-passing recess 11120 and is positioned close to the platform portion 11121. By providing the platform portion 11121 at a lower position in the water-passing recess 11120 and positioning the water-passing outlet 102 close to the platform portion 11121, it is ensured that water in the water-passing cavity 101 can be drained through the water-passing outlet 102, preventing bacteria from growing in the water-passing cavity 101 due to residual water.

[0106] like Figure 13 , Figures 15-16 As shown, the end wall 111 includes a first connecting wall 1111, a first transition wall 1112, a second transition wall 1113, and a second connecting wall 1114. The first connecting wall 1111, the first transition wall 1112, the second transition wall 1113, and the second connecting wall 1114 are all annular structures and are arranged from the outside to the inside in the radial direction of the end wall 111. The second connecting wall 1114 surrounds the outside of the shaft hole 11101. The water passage recess 11120 is defined by the first transition wall 1112 and is located between the second connecting wall 1114 and the second transition wall 1113. The second transition wall 1113 extends obliquely from the outside to the inside in the radial direction of the end wall 111 towards the cylinder opening.

[0107] like Figures 17-19 As shown, the heat exchange plate 12 includes a first mating wall 1251, a first heat exchange wall 124, a second heat exchange wall 121, and a second mating wall 1252. The first mating wall 1251, the first heat exchange wall 124, the second heat exchange wall 121, and the second mating wall 1252 are all annular structures and are arranged from the outside to the inside in the radial direction of the heat exchange plate 12. The second mating wall 1252 surrounds the outside of the clearance hole 1201. The first heat exchange wall 124 and the second heat exchange wall 121 extend obliquely from the outside to the inside in the radial direction of the heat exchange plate 12 toward the cylinder opening.

[0108] The first heat exchange wall 124 and the first transition wall 1112 are arranged opposite each other in the axial direction of the outer cylinder 11, and a part of the water passage cavity 101 is defined between the first heat exchange wall 124 and the water passage recess 11120. The second heat exchange wall 121 and the second transition wall 1113 are arranged opposite each other in the axial direction of the outer cylinder 11, and have different inclination angles. The other part of the water passage cavity 101 is defined between the second heat exchange wall 121 and the second transition wall 1113.

[0109] In some examples, the middle portion of the heat exchange plate 12 extends along the axial direction of the outer cylinder 11 towards the cylinder opening, forming a flow-guiding protrusion on the side of the heat exchange plate 12 facing the cylinder opening, and a clearance groove 1208 is formed on the side of the heat exchange plate 12 facing the end wall 111 to avoid the end wall 111. The heat exchange wall is at least a portion of the peripheral wall of the clearance groove 1208, and the second connecting wall 1114 is at least a portion of the bottom wall of the clearance groove 1208.

[0110] like Figure 3 As shown, in some examples, the end wall 111 has a positioning portion and the heat exchange plate 12 has a positioning mating portion. The positioning mating portion mates with the positioning portion, allowing for pre-positioning before connecting the end wall 111 and the heat exchange plate 12. Specifically, the positioning portion is a positioning protrusion 11141, and the positioning mating portion is a positioning notch 1204 provided on the edge of the clearance hole 1201.

[0111] like Figures 8-10 As shown, in some examples, the first connecting wall 1111 has a plurality of first connecting holes 11111 arranged in its extending direction, and the second connecting wall 1114 has a plurality of second connecting holes 11142 arranged in its extending direction. Correspondingly, the heat exchange plate 12 has a plurality of first mating holes 1206 and a plurality of second mating holes 1207, the plurality of first mating holes 1206 corresponding one-to-one with the plurality of first connecting holes 11111, and the plurality of second mating holes 1207 corresponding one-to-one with the plurality of second connecting holes 11142.

[0112] The heat exchange plate 12 is fixed to the end wall 111 of the outer cylinder 11 by a plurality of first fasteners 151 and a plurality of second fasteners 152. The plurality of first fasteners 151 correspond one-to-one with the positions of a plurality of first connecting holes 11111, and each first fastener 151 passes through the corresponding first connecting hole 11111 and the first mating hole 1206. The plurality of second fasteners 152 correspond one-to-one with the positions of a plurality of second connecting holes 11142, and each second fastener 152 passes through the corresponding second connecting hole 11142 and the second mating hole 1207.

[0113] In some examples, the first connecting wall 1111 is provided with a first mounting groove 11102, and an annular first seal 141 is provided in the first mounting groove 11102. The heat exchange plate 12 is provided with a first abutment protrusion 1202 on the side facing the first connecting wall 1111. The first abutment protrusion 1202 abuts against the first seal 141, thereby ensuring the sealing between the first connecting wall 1111 and the heat exchange plate 12. A plurality of first fasteners 151 are located on the outer periphery of the first seal 141.

[0114] In some examples, the second connecting wall 1114 is provided with a second mounting groove 11103, and an annular second seal 142 is provided in the second mounting groove 11103. The heat exchange plate 12 is provided with a second stop protrusion 1203 on the side facing the second connecting wall 1114. The second stop protrusion 1203 abuts against the second seal 142, thereby ensuring the sealing between the second connecting wall 1114 and the heat exchange plate 12. The second seal 142 is located on the outer periphery of a plurality of second fasteners 152.

[0115] like Figure 13 As shown, in some examples, the cavity wall of the water passage 101 has a turbulence structure 13. Specifically, the turbulence structure 13 includes a turbulence protrusion 131 and / or a turbulence recess 132.

[0116] like Figure 13 , Figure 15 and Figure 16 As shown, a portion of the end wall 111 extends toward the cylinder opening to form a first turbulence protrusion 1311 and a second turbulence protrusion 1312 on the side surface of the end wall 111 facing the cylinder opening. The first turbulence protrusion 1311 is located on the right side of the shaft hole 11101 and extends from the water passage recess 11120 to the second transition wall 1113. The second turbulence protrusion 1312 is located above the shaft hole 11101 and is located in the water passage recess 11120.

[0117] like Figures 17-20 As shown, a portion of the heat exchange plate 12 extends toward the cylinder opening to form a turbulence recess 132 on the side surface of the heat exchange plate 12 facing the end wall 111. The turbulence recess 132 is located on the second heat exchange wall 121 and is axially opposite to the first turbulence protrusion 1311 in the outer cylinder 11.

[0118] In some examples, the outer periphery of the heat exchange plate 12 has a reinforcing flange 123, and the heat exchange plate 12 also has a reinforcing structure 122. At least a portion of the reinforcing structure 122 is located on the first heat exchange wall 124 and is disposed opposite to the water-passing recess 11120, and / or, at least a portion of the reinforcing structure 122 is located on the first mating wall 1251. The reinforcing structure 122 can be a reinforcing recess and / or a reinforcing protrusion. The reinforcing flange 123 and the reinforcing structure 122 can improve the structural strength of the heat exchange plate 12, enhance the deformation resistance of the heat exchange plate 12, and ensure the roundness of the heat exchange plate 12.

[0119] like Figure 7 , Figures 11-12 As shown, in some embodiments, an overflow channel 103 is further defined between the heat exchange plate 12 and the end wall 111. The overflow channel 103 is connected to the water passage cavity 101, specifically, the overflow channel 103 is connected to the overflow port 1012 of the water passage cavity 101.

[0120] In some examples, the first connecting wall 1111 is provided with an overflow groove 11112, and the heat exchange plate 12 and the overflow groove 11112 define an overflow channel 103. The first mating wall 1251 is provided with a reinforcing structure 122, which is axially opposite to the overflow groove 11112 in the outer cylinder 11.

[0121] In some examples, the overflow channel 103 includes a first extension 1031 and a second extension 1032. The first extension 1031 is located outside the water passage cavity 101 and can be formed as an arc-shaped segment extending circumferentially along the water passage cavity 101. The second extension 1032 is located above the shaft hole 11101 and is formed as a straight segment extending radially along the heat exchange plate 12. The lower end of the second extension 1032 communicates with the overflow port 1012 of the water passage cavity 101, and the upper end of the second extension 1032 communicates with the upper end of the first extension 1031.

[0122] like Figure 11 As shown, in some optional embodiments, the number of overflow channels 103 is one. The overflow channel 103 is located on one side of the centerline extending vertically along the end wall 111.

[0123] like Figure 12 As shown, in some alternative embodiments, there are two overflow channels 103, which are located on both sides of the center line extending in the vertical direction of the end wall 111, and the two overflow channels 103 are symmetrically arranged about the center line extending in the vertical direction of the end wall 111.

[0124] like Figures 11-13 As shown, in some embodiments, a portion of the outer cylinder 11's surrounding wall 112 is recessed downwards to form a drainage groove 1122 at the lower part of the surrounding wall 112. The drainage groove 1122 defines a drainage cavity 1121, and the overflow channel 103 communicates with the drainage cavity 1121 through the water outlet channel 104.

[0125] Specifically, the drainage groove 1122 includes a first groove sidewall 11221, a second groove sidewall 11222, and a third groove sidewall 11223. The first groove sidewall 11221 and the second groove sidewall 11222 are arranged opposite to each other in the left-right direction. The third groove sidewall 11223 is arranged opposite to the cylinder opening in the axial direction of the outer cylinder 11, and the third groove sidewall 11223 connects the first groove sidewall 11221 and the second groove sidewall 11222.

[0126] like Figure 14 and Figure 29As shown, the first tank sidewall 11221 is provided with a mounting hole 11224. The clothing handling device 100 also includes a mounting base 51, a temperature detection element 52, and a heating element 53. The temperature detection element 52 and the heating element 53 are both disposed on the mounting base 51, which is located at the mounting hole 11224, and the temperature detection element 52 and the heating element 53 are disposed within the drain cavity 1121. By setting the temperature detection element 52, the overflow temperature of the water flowing out from the overflow channel 103 can be detected. This allows for the determination of the drying degree of the clothes in the inner drum based on the overflow temperature, improving the accuracy of the detection of the drying degree of the clothes, facilitating the control of the working state of the drying module, and reducing energy waste and damage to clothes due to continuous high temperature.

[0127] The clothing handling device 100 also includes a temperature and humidity detector, which can detect the inlet air temperature and humidity, and the outlet air temperature and humidity of the outer drum 11, thereby determining the degree of drying of the clothes in the inner drum. The temperature and humidity detector and the temperature detector 52 work together to improve the accuracy of detecting the degree of drying of the clothes and facilitate the control of the working status of the drying module.

[0128] The garment handling device 100 is adapted to heat the water in the outer drum 11 by heating element 53 during the washing process to increase the water temperature and improve washing efficiency. It also uses temperature detection element 52 to detect the water temperature in the outer drum 11 and controls the working state of heating element 53 based on the detection results. Specifically, it can control heating element 53 to start working, stop working, reduce power working, or increase power working.

[0129] The clothing handling device 100 is adapted to detect the temperature of the water flowing out of the overflow channel 103 through the temperature detection element 52 when the clothes are dry, so as to control the working state of the drying module according to the detection result. Specifically, it may include controlling the drying module to start working, stop working, reduce power working, and increase power working.

[0130] Specifically, if the clothes in the inner drum are damp, the evaporation of moisture will absorb heat, and the air temperature inside the inner drum and outer drum 11 will rise slowly; if the clothes in the inner drum are dry, the evaporation of moisture will decrease, and the air temperature inside the inner drum and outer drum 11 will rise rapidly.

[0131] Therefore, when the temperature sensor 52 detects that the temperature of the water flowing out of the overflow channel 103 is less than or equal to the preset temperature, it can be determined that the clothes in the inner drum are still relatively damp. By controlling the drying module to continue working or to increase its power, hot air can continue to be introduced into the outer drum 11 to continue drying the clothes. When the temperature sensor 52 detects that the temperature of the water flowing out of the overflow channel 103 is greater than the preset temperature, it can be determined that the clothes in the inner drum have been dried. By controlling the drying module to stop working or to reduce its power, energy waste can be reduced, and damage to the clothes due to high temperature can be avoided.

[0132] like Figure 13 and Figure 14 , Figure 28 and Figure 29 As shown, in some embodiments, the water outlet channel 104 includes a first channel 1041 and a second channel 1042. The first channel 1041 is disposed on the end wall 111, and one end of the first channel 1041 is connected to the overflow channel 103. The second channel 1042 is disposed on the surrounding wall 112, and one end of the second channel 1042 is connected to the other end of the first channel 1041. The other end of the second channel 1042 extends towards the cylinder opening and extends above the temperature detection element 52, so that the water flowing out of the second channel 1042 can fall onto the temperature detection element 52, thereby directly detecting the temperature of the water flowing out of the second channel 1042 using the temperature detection element 52.

[0133] The bottom wall of the second channel 1042 gradually extends downward from the end wall 111 to the cylinder opening. An extension plate 113 is provided at the opening of the drainage groove 1122. The extension plate 113 extends axially along the outer cylinder 11 and connects to the first channel side wall 11221 and the third channel side wall 11223. The second channel 1042 is at least partially formed on the extension plate 113. The bottom wall of the second channel 1042 gradually extends downward from the first channel side wall 11221 to the second channel side wall 11222.

[0134] like Figures 22-23 As shown, in some embodiments, the garment handling device 100 further includes a water valve 30, which can be fixed to the outer surface of the end wall 111 of the outer cylinder 11 by a fastener.

[0135] like Figures 24-27 As shown, the water valve 30 includes a valve body 31, which has an inlet port 3111, a water passage port 3112, a drain port 3113, and an overflow port 3114. The inlet port 3111 can be connected to an inlet structure (e.g., an inlet pipe), the water passage port 3112 can be connected to the water passage 102 via a water passage pipe 40, the drain port 3113 can be connected to a drain structure (e.g., a drain pipe), and the overflow port 3114 can be connected to the overflow hole of the outer cylinder 11 via an overflow pipe.

[0136] The valve body 31 defines an inlet channel 3121, a water passage 3122, a drain channel 3123, and an overflow channel 3124. One end of the inlet channel 3121 is connected to the inlet port 3111, one end of the water passage 3122 is connected to the water passage port 3112, the drain channel 3123 extends in the vertical direction, the lower end of the drain channel 3123 is connected to the drain port 3113, and one end of the overflow channel 3124 is connected to the overflow port 3114.

[0137] like Figure 24 and Figure 25As shown, in some optional examples, the other end of the water inlet channel 3121 is connected to the upper end of the drain channel 3123. The water inlet channel 3121 has a tapering section 31211 at a position away from the water inlet interface 3111. The flow area of ​​the tapering section 31211 gradually decreases in the direction away from the water inlet interface 3111. The other end of the water passage 3122 is connected to the middle of the water inlet channel 3121. The connection position between the water passage 3122 and the water inlet channel 3121 is located between the water inlet interface 3111 and the tapering section 31211. The other end of the overflow channel 3124 is connected to the middle of the drain channel 3123.

[0138] The water valve 30 also includes a sealing element 32, which is a spherical structure and is movably disposed in the water inlet channel 3121. When the sealing element 32 moves to the water inlet interface 3111, it can close the water inlet interface 3111, so that the drainage channel 3123 and the water passage channel 3122 are connected through the water inlet channel 3121. When the sealing element 32 moves to the tapered section 31211, it can cut off the water inlet channel 3121 and the drainage channel 3123, and connect the water inlet channel 3121 and the water passage channel 3122.

[0139] like Figure 26 and Figure 27 As shown, in some alternative examples, the other end of the water inlet channel 3121 and the other end of the water passage 3122 are both connected to the upper end of the drainage channel 3123 through the water passage 3125, and the flow area of ​​the water passage 3125 is smaller than the flow area of ​​the water passage 3122.

[0140] When the garment handling device 100 executes the washing program, water can be injected into the outer drum 11. After water injection is completed or during the water injection process, the drive device drives the inner drum to rotate inside the outer drum 11. The inner drum can lift the clothes to a certain height. When it exceeds a certain height, the clothes can fall freely under the action of gravity, thereby generating an impact force on the clothes and achieving the washing effect. Since an overflow hole is provided at the top of the outer drum 11, when the water level in the outer drum 11 rises to the overflow hole, the water in the outer drum 11 can be discharged from the overflow hole, flowing through the overflow pipe and the water valve 30, and finally discharged to a specific area. After the washing is completed, the washing water in the outer drum 11 can be discharged using a drain pump.

[0141] When the clothing handling device 100 executes the drying program, the drive device drives the inner drum to rotate inside the outer drum 11. The inner drum can cause the clothes to tumble, and the drying module can introduce hot air into the outer drum 11 to dry the clothes in the inner drum.

[0142] During the drying process, the water inlet pipe can supply water to the water outlet 102 through the water valve 30 and the water pipe 40. At this time, the water outlet 102 is used as the water inlet 1011. The water outlet 102 can supply water at a lower temperature into the water outlet cavity 101. The water exchanges heat with the heat exchange plate 12, which can reduce the temperature of the heat exchange plate 12. The heat exchange plate 12 can condense the hot air in the outer drum 11, so that the water vapor in the hot air condenses into liquid water and is discharged from the outer drum 11, thereby quickly drying the clothes in the inner drum.

[0143] When the water level in the water passage 101 rises to the overflow port 1012, the higher temperature water overflows from the overflow port 1012 and is guided to the drain chamber 1121 through the overflow channel 103. Finally, the water in the drain chamber 1121 is discharged by the drain pump. By continuously introducing lower temperature water into the water passage 101, the heat exchange between the water in the water passage 101 and the heat exchange plate 12, and between the heat exchange plate 12 and the hot air in the outer cylinder 11, is more complete.

[0144] During this process, the first turbulence protrusion 1311, the second turbulence protrusion 1312, and the turbulence recess 132 can extend the flow path of water in the water passage cavity 101, so that the water and the heat exchange plate 12 can exchange heat fully, and the water can be distributed more evenly in the water passage cavity 101, avoiding local overheating or undercooling of the heat exchange plate 12. This is beneficial to improving the temperature uniformity of the heat exchange plate 12, thereby improving the condensation effect of the heat exchange plate 12 on the hot air in the outer cylinder 11, and thus improving the drying efficiency and drying effect of the clothes handling device 100.

[0145] After the clothes handling device 100 finishes drying the clothes, the water outlet 102 is used as a drain outlet. The water in the water passage chamber 101 can be discharged from the water outlet 102 through the water pipe 40 to the water valve 30, and finally discharged to a specific area through the drain pipe. Since the water outlet 102 is located at the lower part of the outer drum assembly 10, the water in the water passage chamber 101 can be completely drained, reducing water residue.
