Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment, and in particular to a clothing processing device. Background Technology

[0002] In related technologies, such as those disclosed in JP2008167892A, clothing handling equipment, such as a washing machine, includes a clutch, an outer tub, and a sealing bracket 63. A gasket 63a is provided at the bottom of the outer tub, and the lower end of the sealing bracket 63 is clamped to the outer periphery of the gasket 63a, thereby completing the assembly of the sealing bracket 63. However, there are assembly errors in the assembly process of the first sealing bracket 63, and the gasket 63a has a strong stopping effect on the sealing bracket 63, which makes it impossible to eliminate the assembly error of the seal of this type of clothing handling device, thereby easily causing uneven wear of the first seal. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a garment processing device that can compensate for the problem of misalignment between the first seal and the clutch shaft caused by manufacturing precision and assembly errors of the first seal, thereby extending the service life of the first seal.

[0004] The garment processing device according to the present invention includes: an outer tub having a first connecting hole in its bottom wall; an inner tub rotatably disposed within the outer tub; and a water guiding assembly disposed between the bottom of the inner tub and the bottom wall of the outer tub to form at least a portion of a drainage channel, the water guiding assembly including a first sealing member, the first sealing member including a bottom ring portion connected to the bottom wall of the outer tub, the bottom ring portion having a second connecting hole, the second connecting hole being disposed opposite to the first connecting hole, a connecting member adapted to pass through the first connecting hole and the second connecting hole to assemble the first sealing member to the bottom wall of the outer tub; the diameter of the second connecting hole is larger than the diameter of the first connecting hole.

[0005] This invention directly connects the first sealing element to the bottom wall of the outer barrel, eliminating the gasket of the prior art and thus reducing the limiting effect on the first sealing element. At the same time, this invention sets the diameter of the second connecting hole to be larger than that of the first connecting hole, so that the connector still has a certain amount of room to move within the second connecting hole of the first sealing element, which can partially offset the error caused by assembly and reduce the uneven wear of the first sealing element.

[0006] According to the garment processing device of the present invention, by making the diameter of the second connecting hole larger than the diameter of the first connecting hole, the problem of misalignment between the first seal and the clutch shaft caused by manufacturing precision and assembly errors of the first seal can be offset, thereby extending the service life of the first seal.

[0007] In some examples of the present invention, the bottom ring and the first seal are integral.

[0014] In some examples of the present invention, the difference between the width of the sealing groove and the width of the sealing rib is 1.5mm ± 0.5mm.

[0015] In some examples of the present invention, there are multiple first connecting holes that are spaced apart circumferentially, and a first base circle is formed by connecting the center of each first connecting hole. The sealing groove includes a first concave section located inside the first base circle and a first convex section located at least partially outside the first base circle. There are multiple first concave sections and multiple first convex sections that are spaced apart. The multiple first connecting holes and the multiple first concave sections are arranged radially opposite to each other along the first base circle.

[0016] In some examples of the present invention, the drain hole is a single hole and is arranged radially opposite to one of the first convex segments along the first base circle.

[0017] In some examples of the present invention, the bottom ring portion includes a bottom ring skeleton and a bottom ring cladding. The bottom ring skeleton includes a plurality of support portions spaced apart circumferentially along the bottom ring portion. Each support portion is correspondingly formed with a second connecting hole. The bottom ring cladding covers the portion of the bottom ring skeleton other than the support portions.

[0018] In some examples of the present invention, the water guiding assembly further includes a sealing disc, and one end of the first seal is provided with a lip, the lip being sealed to the outer peripheral wall of the sealing disc to define the drainage channel between the sealing disc, the first seal, and the outer barrel.

[0062] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0063] The following is for reference. Figures 1-7 A garment processing apparatus 100 according to an embodiment of the present invention is described. The garment processing apparatus 100 may be a washing machine.

[0064] like Figures 1-3 As shown, the garment processing device 100 according to an embodiment of the present invention includes: an outer tub 10, an inner tub 20, a clutch 30, and a water guiding assembly.

[0065] like Figure 4 and Figure 7 As shown, the bottom wall of the outer barrel 10 has a first connecting hole 14 (i.e., the first connecting part 14), a drain hole 12, and a shaft hole 11. The bottom wall of the outer barrel 10 has a sealing groove 13, which is disposed on the upper surface of the bottom wall of the outer barrel 10. The sealing groove 13 is configured as an annular groove. The shaft hole 11 and the drain hole 12 are both located in the inner ring area of ​​the sealing groove 13. The first connecting hole 14 is located in the outer ring area of ​​the sealing groove 13. In the radial direction of the bottom wall of the outer barrel 10, the shaft hole 11 and the drain hole 12 are both located inside the sealing groove 13, and the first connecting hole 14 is located outside the sealing groove 13. The sealing groove 13 includes a first outer ring groove wall 132 and a first inner ring groove wall 131. In the radial direction of the bottom wall of the outer barrel 10, the drain hole 12 and the shaft hole 11 are both located inside the first inner ring groove wall 131.

[0066] The inner tub 20 is rotatably disposed inside the outer tub 10. The bottom wall of the inner tub 20 has a water outlet 21. Specifically, the inner tub 20 has a clothing storage space 22. The axial side of the inner tub 20 (e.g., Figure 1 The upper side (shown in the image) is open to define a clothing inlet 23 communicating with the holding space. The outer tub 10 has a receiving space 18, and one axial side of the outer tub 10 (e.g., Figure 1 The upper side (shown in the image) is open, and the inner tub 20 is rotatably disposed within the accommodating space 18 of the outer tub 10. Users can place clothes into the holding space of the inner tub 20 through the clothes inlet 23, or take clothes out of the holding space of the inner tub 20 through the clothes inlet 23, thus making it convenient for users to use.

[0067] like Figure 3 and Figure 4As shown, the clutch 30 includes a washing shaft 32 and a spin-drying shaft 31. The spin-drying shaft 31 passes through a shaft hole 11 and is used to drive the inner tub 20 to rotate. The spin-drying shaft 31 is hollow, and the washing shaft 32 can pass through it. The bottom wall of the outer tub 10 has a shaft hole 11 (for example, a shaft hole 11 is provided at the center of the bottom of the outer tub 10). The spin-drying shaft 31 and the washing shaft 32 located inside the spin-drying shaft 31 can extend from the outside of the outer tub 10 through the shaft hole 11 into the outer tub 10. The spin-drying shaft 31 is connected to the bottom wall of the inner tub 20, while the washing shaft 32 further passes through the bottom wall of the inner tub 20 and is connected to the impeller 24 located inside the inner tub 20. Therefore, the rotation of the spin-drying shaft 31 can drive the inner tub 20 to rotate, and the rotation of the washing shaft 32 can drive the impeller 24 to rotate, thereby realizing the washing and spin-drying functions of the clothing processing equipment 100. The washing and dehydration principles of the garment processing equipment 100 are well known to those skilled in the art, and will not be described in detail here.

[0068] like Figure 3 and Figure 4 As shown, the water guiding component is disposed between the bottom of the inner tub 20 and the bottom wall of the outer tub 10, defining a drainage channel 41 between the inner tub 20 and the outer tub 10, connecting the water outlet 21 and the drain hole 12. Further, the water guiding component is sleeved outside the dehydration shaft 31, and is located between the bottom wall of the outer tub 10 and the bottom wall of the inner tub 20. The water guiding component can define a drainage channel 41 between the inner tub 20, the outer tub 10, and the dehydration shaft 31, and the drainage channel 41 connects the drain hole 12 and the water outlet 21. Figure 12 As shown, the water guiding assembly includes a first seal 42, which includes a bottom ring portion 421 connected to the bottom wall of the outer tub 10. Further, the bottom ring portion 421 is disposed on the upper surface of the bottom wall of the outer tub 10, and the bottom ring portion 421 has a second connecting hole 423. The second connecting hole 423 is disposed opposite to the first connecting hole 14, and the diameter of the second connecting hole 423 is larger than the diameter of the first connecting hole 14. The outer tub 10 and the bottom ring portion 421 are adapted to be connected by fasteners passing through the second connecting hole 423 and the first connecting hole 14.

[0069] This invention directly connects the first seal to the bottom wall of the outer tub, eliminating the need for the gasket in existing technology and thus reducing the limiting effect on the first seal. Simultaneously, the invention sets the diameter of the second connecting hole to be larger than that of the first connecting hole, allowing the connector some room to move within the second connecting hole of the first seal. This provides the first seal with some room to move, partially offsetting assembly errors and reducing uneven wear on the first seal. Ensuring the assembly precision of the garment processing equipment 100 extends the service life of the first seal 42.

[0070] Furthermore, the bottom ring portion 421 is provided with an annular sealing rib 422. The sealing rib 422 is provided on the bottom surface of the bottom ring portion 421. The sealing rib 422 is set as an annular rib and is embedded between the first outer ring groove wall 132 and the first inner ring groove wall 131 of the sealing groove 13.

[0071] In some embodiments of the present invention, the bottom ring portion 421 and the first seal 42 are integral parts, that is, the bottom ring portion 421 is part of the first seal 42. This arrangement can improve the overall structural strength of the bottom ring portion 421 and the first seal 42, further reduce the wear of the first seal 42, and further solve the coaxiality problem caused by assembly errors.

[0072] In some embodiments of the present invention, such as Figure 11 and Figure 12 As shown, the first seal 42 is formed as an annular ring extending throughout the circumference of the dehydration shaft 31. A rotational seal can be formed between the first seal 42 and the sealing disc 44. This arrangement allows the outer periphery of the sealing disc, the first seal 42, the bottom of the outer tub 10, and the bottom of the inner tub 20 to define a drainage channel 41. The drainage channel 41 extends annularly in the circumference of the dehydration shaft 31. The drain hole 12 on the bottom wall of the outer tub 10 and the water outlet hole 21 on the bottom wall of the inner tub 20 are both connected to the drainage channel 41. With this arrangement, water in the inner tub 20 can enter the drainage channel 41 through the water outlet hole 21, and water in the drainage channel 41 can be further discharged through the drain hole 12 on the bottom wall of the outer tub 10.

[0073] In some embodiments of the present invention, the first sealing element 42 includes a first annular sealing ring and a second annular sealing ring, wherein the first annular sealing ring surrounds the outer periphery of the second annular sealing ring and is connected to the second annular sealing ring, the second annular sealing ring is in a stop-fitting engagement with the sealing disc 44, the first annular sealing ring is in a fit with the outer barrel 10, and the bottom ring portion 421 is disposed on the first annular sealing ring. Thus, the structure is simple and easy to manufacture.

[0074] In some specific examples of the present invention, the first annular sealing ring includes: an annular ring extending in an axial direction into a cylindrical shape on the dehydration shaft 31; a bottom ring portion 421 disposed on the outer peripheral wall of one end of the annular ring adjacent to the bottom wall of the outer tub 10; and the bottom ring portion 421 extending in an annular direction in the circumferential direction of the annular ring; the bottom ring portion 421 being detachably connected to the bottom wall of the outer tub 10. This detachable connection between the bottom ring portion 421 and the bottom wall of the outer tub 10 further improves the reliability of the installation of the first seal 42 and the outer tub 10. Furthermore, if the first seal 42 is damaged after long-term use, it is convenient to remove the first seal 42 from the outer tub 10 for repair and replacement.

[0075] In some specific examples of the present invention, the water guiding assembly may further include a sealing disc 44, and one end of the first sealing member 42 is provided with a lip, which seals against the outer peripheral wall of the sealing disc 44 to define a drainage channel 41 between the sealing disc 44, the first sealing member 42, and the outer tub 10. A second annular sealing ring forms the lip, is located at one end of the annular sealing ring near the bottom wall of the inner tub 20, and seals against the sealing disc 44, thereby achieving a seal between the first sealing member 42 and the sealing disc 44.

[0076] Specifically, the inner tub 20 is a perforated inner tub 20, which means that the water in the inner tub 20 can only enter the drainage channel 41 located in the outer tub 10 through the water outlet 21, and cannot enter other parts of the outer tub 10.

[0077] It should be noted that by embedding the sealing rib 422 between the first outer ring groove wall 132 and the first inner ring groove wall 131 of the sealing groove 13, the sealing rib 422 can be reliably installed in the sealing groove 13. The sealing rib 422 can effectively seal the gap between the first sealing member 42 and the bottom wall of the outer tub 10, thereby improving the sealing performance between the first sealing member 42 and the bottom wall of the outer tub 10. This can prevent liquid (e.g., water) in the drainage channel 41 from flowing from the gap between the first sealing member 42 and the bottom wall of the outer tub 10 to the space between the outer tub 10 and the inner tub 20, thereby preventing the clothing handling equipment 100 from leaking.

[0078] In related technologies, garment processing equipment generally uses a clutch with a drainage channel, and the clutch is assembled and connected with the inner tub and the outer tub to achieve the purpose of drainage. The clutch has a complex structure, and the overall assembly structure of the clutch with the inner tub and the outer tub is complex, which is not conducive to maintenance and replacement, and the cost is high.

[0079] In view of this, the garment processing device 100 according to the embodiment of the present invention, by providing a first sealing member 42, which is disposed between the bottom of the inner tub 20 and the bottom of the outer tub 10 and surrounds the outer periphery of the dehydration shaft 31, allows the dehydration shaft 31, the first sealing member 42, the bottom wall of the outer tub 10 and the bottom wall of the inner tub 20 to define a drainage channel 41. The drainage channel 41 is connected to the drainage hole 12 of the bottom wall of the outer tub 10 and the water outlet hole 21 of the bottom wall of the inner tub 20, respectively, thereby realizing the discharge of water in the inner tub 20. This not only has a simple structure and is easy to install, but also eliminates the need for a clutch 30 with a drainage channel, allowing the use of a common clutch 30, which facilitates maintenance and replacement and reduces costs.

[0080] Therefore, by embedding the sealing rib 422 in the sealing groove 13, the sealing performance between the first sealing element 42 and the bottom wall of the outer barrel 10 can be improved, which can effectively prevent liquid from flowing between the outer barrel 10 and the inner barrel 20.

[0081] In some embodiments of the present invention, the difference between the radius of the second connecting hole 423 and the radius of the first connecting hole 14 is greater than 0.5 mm. This can also be understood as the difference between the radius of the second connecting hole 423 and the radius of the first connecting hole 14 being greater than 0.5 mm. Further, the difference between the radius of the second connecting hole 423 and the radius of the first connecting hole 14 is 1.5 mm ± 0.5 mm. Preferably, the radius of the second connecting hole 423 is 1.5 mm larger than the radius of the first connecting hole 14. Further, the fastener can be a bolt or a screw. For example, taking a screw as an example, the inner diameter of the second connecting hole 423 is larger than the outer diameter of the screw. Preferably, the inner diameter of the second connecting hole 423 is 1.5 mm larger than the outer diameter of the screw. The gap between the inner diameter of the second connecting hole 423 and the outer diameter of the screw can compensate for the misalignment of the first seal 42 and the clutch 30 due to manufacturing precision and assembly errors. This can further ensure the assembly precision of the garment processing device 100 and further ensure the service life of the first seal 42. However, the present invention is not limited thereto, and the fastener can also be set as a rivet.

[0082] In some embodiments of the present invention, the first connecting hole 14 is configured as a threaded hole and the second connecting hole 423 is configured as a smooth hole. This configuration facilitates the fastener passing through the second connecting hole 423, which can improve the assembly efficiency of the first seal 42 and the bottom wall of the outer barrel 10. Furthermore, by connecting the fastener with the threaded connection of the first connecting hole 14, the first seal 42 can be securely installed on the bottom wall of the outer barrel 10, which can prevent the first seal 42 from separating from the outer barrel 10 and facilitate the disassembly and assembly of the first seal 42.

[0083] In some embodiments of the present invention, the second connecting hole 423 can be configured as a circular hole, the radius of which is larger than the radius of the first connecting hole 14. Of course, the second connecting hole 423 may not be circular; for example, it can be an oblong hole, where the minimum diameter of the center of the oblong hole is its diameter. This simplifies the structure of the second connecting hole 423, making it easier to install on the bottom ring portion 421 and improving the production efficiency of the first seal 42.

[0084] In some embodiments of the present invention, such as Figure 4 As shown, the drain hole 12 is located on the radial side of the dewatering shaft 31. Specifically, for example, as... Figure 7As shown, there is only one drain hole 12, and the drain hole 12 is located on one radial side of the dehydration shaft 31. Alternatively, there may be multiple drain holes 12, forming a group of drain holes located on one radial side of the dehydration shaft 31, with the multiple drain holes 12 spaced apart in the radial direction of the dehydration shaft 31. Of course, the invention is not limited to this; in other embodiments, there may be multiple drain holes 12, spaced apart in the circumferential direction of the dehydration shaft 31.

[0085] In some embodiments of the present invention, the width of the sealing groove 13 is greater than the width of the sealing rib 422, that is, the width of the sealing groove 13 is greater than the width of the sealing rib 422. Further, half of the difference between the width of the sealing groove 13 and the width of the sealing rib 422 is greater than 0.5 mm. More specifically, the difference between the width of the sealing groove 13 and the width of the sealing rib 422 is 1.5 mm ± 0.5 mm. Preferably, the difference between the width of the sealing groove 13 and the width of the sealing rib 422 is 1.5 mm. This arrangement facilitates the installation of the sealing rib 422 within the sealing groove 13, improves the assembly efficiency of the first sealing element 42 and the outer barrel 10, and ensures that the sealing rib 422 can be assembled into the sealing groove 13. Furthermore, after the sealing rib 422 is installed in the sealing groove 13, the gap between the sealing rib 422 and the sealing groove 13 can offset the problem of misalignment between the first seal 42 and the clutch 30 due to manufacturing precision and assembly errors. This can ensure the assembly precision of the garment processing equipment 100 and also ensure the service life of the first seal 42.

[0086] In some optional embodiments of the invention, the first seal 42 is detachably connected to the outer tub 10. This facilitates disassembly and assembly, allowing the first seal 42 to be easily removed from the outer tub 10 for repair and replacement should it become damaged after prolonged use.

[0087] In some embodiments of the present invention, such as Figure 7As shown, there are multiple first connecting holes 14, and the multiple first connecting holes 14 are spaced apart circumferentially. Further, the multiple first connecting holes 14 are arranged around the shaft hole 11. The bottom wall of the outer barrel 10 has multiple first connecting holes 14. The multiple first connecting parts 14 can be arranged around the shaft hole 11. The multiple first connecting parts 14 are arranged spaced apart circumferentially in the shaft hole 11. The outer barrel 10 can be connected to the bottom ring part 421 through the first connecting parts 14. In the radial direction of the bottom wall of the outer barrel 10, the first connecting parts 14 can be located outside the first outer ring groove wall 132 of the sealing groove 13. By connecting multiple first connecting parts 14 to the bottom ring part 421 simultaneously, the first sealing element 42 can be reliably installed on the bottom wall of the outer barrel 10, which can prevent the first sealing element 42 from separating from the bottom wall of the outer barrel 10. In addition, it can also ensure that the sealing rib 422 is firmly installed in the sealing groove 13, which can prevent the sealing rib 422 from moving out of the sealing groove 13, thereby ensuring the sealing between the first sealing element 42 and the bottom wall of the outer barrel 10.

[0088] In some embodiments of the present invention, such as Figure 7 As shown, a first base circle 15 is formed at the center of each first connecting part 14. The sealing groove 13 may include a first concave section 133 and a first convex section 134. In the radial direction of the bottom wall of the outer barrel 10, the first concave section 133 is located inside the first base circle 15, and at least a portion of the first convex section 134 is located outside the first base circle 15. The first connecting part 14 is arranged radially along the first base circle 15 corresponding to the first concave section 133, and the drain hole 12 is arranged radially along the first base circle 15 corresponding to the first convex section 134. Figure 7 As shown, this arrangement allows the sealing groove 13 to be configured as an irregular (i.e., lace-shaped) structure, which can make the sealing groove 13 and the drain hole 12 avoid each other. It can also make the first connecting part 14 and the sealing groove 13 avoid each other, which can prevent the first connecting part 14 and the sealing groove 13 from interfering with each other, thereby ensuring the assembly reliability between the first sealing member 42 and the bottom wall of the outer barrel 10.

[0089] In some embodiments of the present invention, such as Figure 7As shown, multiple first protruding sections 134 and multiple first concave sections 133 can be provided, and these multiple first protruding sections 134 and multiple first concave sections 133 are arranged alternately. Further, in the circumferential direction of the bottom wall of the outer barrel 10, multiple first protruding sections 134 and multiple first concave sections 133 are arranged alternately. A first concave section 133 can be connected between two adjacent first protruding sections 134, and a first protruding section 134 can be connected between two adjacent first concave sections 133. The shape of the sealing rib 422 matches the shape of the sealing groove 13. Multiple first connecting holes 14 and multiple first concave sections 133 are arranged radially opposite to each other along the first base circle 15. A first connecting part 14 and a first concave section 133 are arranged radially opposite to each other along the first base circle 15. A drain hole 12 can be provided, and the drain hole 12 and one of the first protruding sections 134 are arranged radially opposite to each other along the first base circle 15. This configuration allows the sealing groove 13 to be set as a regular lace-shaped structure. By matching the shape of the sealing rib 422 with the shape of the sealing groove 13, the sealing rib 422 can be assembled without directionality, and the sealing rib 422 can be quickly installed in the sealing groove 13.

[0090] In some embodiments of the present invention, such as Figure 7 As shown, Figure 11 As shown, the bottom ring portion 421 has a second connecting hole 423, which is opposite to the first connecting hole 14. The outer barrel 10 and the bottom ring portion 421 are adapted to be connected by fasteners passing through the second connecting hole 423 and the first connecting hole 14. Multiple second connecting holes 423 can also be provided, spaced apart in the circumferential direction of the bottom ring portion 421. Each second connecting hole 423 corresponds to a first connecting hole 14. By simultaneously inserting fasteners through the second connecting holes 423 and the first connecting holes 14, the first sealing element 42 can be securely installed on the bottom wall of the outer barrel 10, and the sealing rib 422 can be pressed against the sealing groove 13, thereby improving the sealing performance between the first sealing element 42 and the bottom wall of the outer barrel 10.

[0091] In some embodiments of the present invention, a plurality of second connecting holes 423 are evenly spaced apart in the circumferential direction of the bottom ring portion 421, and a plurality of fasteners, a plurality of second connecting holes 423, and a plurality of first connecting holes 14 are correspondingly fitted together. This helps to ensure the uniformity of the connection force and further improves the reliability of the fit between the bottom ring portion 421 and the outer barrel 10.

[0092] In some embodiments of the present invention, such as Figure 12 and Figure 16As shown, the bottom ring portion 421 may include a bottom ring sheath 425 and a bottom ring skeleton 424. The bottom ring skeleton 424 may be a metal skeleton, and the bottom ring sheath 425 may be a rubber sheath. The bottom ring skeleton 424 includes a plurality of support portions 426 spaced apart circumferentially along the bottom ring portion 421. Each support portion 426 corresponds to a second connecting hole 423. The bottom ring sheath 425 covers the portion of the bottom ring skeleton 424 excluding the support portions 426. By not providing the bottom ring sheath 425 on the support portions 426, and by installing the fasteners into the second connecting holes 423, a rigid fixed connection between the fasteners and the second connecting holes 423 can be ensured, thereby preventing the fasteners from loosening.

[0093] The clutch 30 can be installed and fixed on the outer barrel 10 first, and then the first seal 42 can be fitted onto the sealing disc 44. The sealing rib 422 of the first seal 42 is aligned and pressed onto the sealing groove 13 of the outer barrel 10. The first seal 42 is fixed to the outer barrel 10 with screws when it is not subjected to external force.

[0094] In some embodiments of the present invention, such as Figure 4 and Figure 17 As shown, the garment processing device 100 may further include a water receiving box 50, which may be located below the outer tub 10 and connected to the drain hole 12. The water receiving box 50 may be located on the bottom wall of the outer tub 10, and has a water inlet 52 that is sealed to the drain hole 12. This arrangement allows water discharged from the drain hole 12 to flow through the water inlet 52 into the water receiving box 50, thus improving the water flow guidance effect.

[0095] In some embodiments of the present invention, such as Figure 25 As shown, the water receiving box 50 includes: a water inlet 52, a water conveying section 58, and a drain section 59. The water inlet 52 extends axially along the outer tub 10, the water conveying section 58 extends radially along the outer tub 10, one end of the water conveying section 58 adjacent to the centerline of the outer tub 10 is connected to the other end of the water inlet 52 away from the outer tub 10, and one end of the drain section 59 is connected to the other end of the water conveying section 58 away from the centerline of the outer tub 10. The drain section 59 is provided with a drain port 57. Therefore, the water receiving box 50 has a simple structure and a reasonable structural layout.

[0096] In related technologies, the water collection box is not installed securely, and there is a risk that the water collection box will fall off during the transportation or long-term use of the garment processing equipment.

[0097] In view of this, such as Figure 4 , Figure 8 and Figure 21As shown, in the clothing processing device 100 according to an embodiment of the present invention, the bottom wall of the outer tub 10 has a first insertion portion 16, the water receiving box 50 has a second insertion portion 51, the drain hole 12 passes through the first insertion portion 16, the second insertion portion 51 has a water inlet hole 52, the second insertion portion 51 and the first insertion portion 16 are inserted and engaged, so that the drain hole 12 and the water inlet hole 52 can be connected, and a second sealing member 53 is provided between the peripheral wall surface of the second insertion portion 51 and the first insertion portion 16. Specifically, by providing a second sealing element 53 between the peripheral wall of the second insertion part 51 and the first insertion part 16, the second sealing element 53 can seal the gap between the peripheral wall of the second insertion part 51 and the first insertion part 16, preventing liquid from flowing out from between the peripheral wall of the second insertion part 51 and the first insertion part 16. Furthermore, by placing the second sealing element 53 between the peripheral wall of the second insertion part 51 and the first insertion part 16, space can be saved. When liquid flows to the drain hole 12 and the inlet hole 52, the liquid exerts a certain lateral pressure on the second insertion part 51. The first insertion part 16 and the second insertion part 51 squeeze the second sealing element 53, which can improve the sealing effect of the second sealing element 53 and reduce the risk of the water receiving box 50 falling off.

[0098] In some embodiments of the present invention, such as Figure 24 and Figure 25 As shown, the second insertion part 51 has a limiting groove 54, which can be disposed on the outer peripheral wall of the second insertion part 51. The second sealing member 53 can be sleeved on the outer peripheral wall of the second insertion part 51 and can be limited and fitted in the limiting groove 54. The second sealing member 53 can be configured as a sealing ring. This configuration allows the second sealing member 53 to be assembled in the limiting groove 54. Furthermore, part of the structure of the second sealing member 53 protrudes from the opening of the limiting groove 54. After the second insertion part 51 and the first insertion part 16 are inserted and fitted together, it can be ensured that the second sealing member 53 can seal the gap between the peripheral wall surface of the second insertion part 51 and the first insertion part 16.

[0099] Furthermore, the design depth of the limiting groove 54 is between 1 / 2 and 2 / 3 of the diameter of the second seal 53. After the second seal 53 is installed in the limiting groove 54, it can ensure that part of the structure of the second seal 53 protrudes out of the opening of the limiting groove 54.

[0100] Furthermore, such as Figure 25 As shown, the upper outer surface of the second insertion part 51 may be provided with a chamfer 56. When the second sealing member 53 is installed in the limiting groove 54, the chamfer 56 can guide the second insertion part 51 to be smoothly inserted into the insertion groove 17.

[0101] In some embodiments of the present invention, such as Figure 4 and Figure 8As shown, the first insertion part 16 can define an open insertion groove 17 at the bottom. The insertion groove 17 can be configured as an annular groove, and the insertion groove 17 includes a second outer annular groove wall 172 and a second inner annular groove wall 171. The second insertion part 51 is inserted between the second outer annular groove wall 172 and the second inner annular groove of the insertion groove 17. Wherein, after the second plug part 51 is inserted between the second outer ring groove wall 172 and the second inner ring groove of the plug groove 17, a second sealing element 53 is sandwiched between the second outer ring groove wall 172 and the second plug part 51. This arrangement can improve the sealing performance between the first plug part 16 and the second plug part 51, and improve the waterproof performance between the first plug part 16 and the second plug part 51, thereby better preventing liquid from flowing out between the first plug part 16 and the second plug part 51. In addition, when the liquid flows through the drain hole 12 and the water inlet hole 52, the liquid exerts a certain lateral pressure on the second plug part 51 and the side wall of the plug groove 17. The first plug part 16 and the second outer ring groove wall 172 squeeze the second sealing element 53, which can improve the sealing effect of the second sealing element 53 and further reduce the risk of the water receiving box 50 falling off.

[0102] Furthermore, a sealant can be provided between the inner surface of the insertion groove 17 and the second insertion part 51. This arrangement can further improve the sealing between the inner surface of the insertion groove 17 and the second insertion part 51, thereby effectively preventing water leakage between the inner surface of the insertion groove 17 and the second insertion part 51.

[0103] In some embodiments of the present invention, such as Figure 21 and Figure 22 As shown, the outer tub 10 has a second connecting portion, and the water receiving box 50 has a third connecting portion 55. The third connecting portion 55 is adapted to connect with the second connecting portion to fix the outer tub 10 and the water receiving box 50 together. The second connecting portion can be configured as a third connecting hole, and the third connecting portion 55 can be configured as a fourth connecting hole. Screws can be installed in the second connecting portion and the third connecting portion 55 to assemble the outer tub 10 and the water receiving box 50 together.

[0104] Furthermore, on the outer barrel 10, the sealing groove 13 is positioned diagonally above the second outer ring groove wall 172, and the distance between the sealing groove 13 and the top of the second outer ring groove wall 172 is preferably 1mm-3mm, and more preferably 2mm. Since the sealing groove 13 and the sealing rib 422 of the first sealing element 42 require the first sealing element 42 to have good strength and be resistant to deformation, and the second outer ring groove wall 172 of the insertion groove 17 can serve as a structural reinforcement, this arrangement can improve the structural strength of the first sealing element 42 and reduce the risk of deformation of the first sealing element 42.

[0105] In some embodiments of the present invention, the water guiding assembly may include: a third seal 45, a connecting plate 43, and a sealing plate 44. The connecting plate 43 is disposed below the bottom wall of the inner tub 20 and is fixedly connected to the inner tub 20. The sealing plate 44 is disposed below the connecting plate 43. The connecting plate 43 and the sealing plate 44 are connected to the dewatering shaft 31. The first seal 42 is sleeved on the sealing plate 44 and is sealed to the sealing plate 44. The third seal 45 is disposed between the connecting plate 43 and the sealing plate 44. The drainage channel 41 includes a first sub-channel, a second sub-channel, and a third sub-channel. The first sub-channel is formed on the connecting plate 43, the second sub-channel is formed on the third seal 45, and the third sub-channel is formed on the sealing plate 44. Multiple second sub-channels, first sub-channels, and third sub-channels are provided, and the multiple second sub-channels, multiple first sub-channels, and multiple third sub-channels are arranged opposite to each other. The liquid flowing out of the outlet 21 flows into the first sub-channel, then into the second sub-channel and the third sub-channel in sequence. The liquid flows from the third sub-channel into the drain outlet, and then from the drain outlet into the water collection box 50. The liquid is then discharged from the water collection box 50.

[0106] Specifically, the sealing disc 44 is disposed on the side surface of the connecting disc 43 facing the bottom wall of the outer tub 10. The sealing disc 44 protrudes from the bottom wall of the connecting disc 43. The first sealing member 42 abuts against the outer peripheral wall of the sealing disc 44. The sealing disc 44, the first sealing member 42, the bottom of the outer tub 10, and the outer peripheral wall of the dehydration shaft 31 define the drainage channel 41. The water outlet 21 penetrates the bottom wall of the inner tub 20, the sealing disc 44, and the connecting disc 43. Thus, by providing the connecting disc 43, the structural strength of the inner tub 20 is improved.

[0107] In some embodiments of the present invention, the connecting disc 43 and the inner tub 20 are integrally formed. Therefore, this integral structure not only ensures the structural and performance stability of the connecting disc 43 and the inner tub 20, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the connecting disc 43 and the inner tub 20 and ensuring the reliability of their connection. Moreover, the integrally formed structure has higher overall strength and stability, is easier to assemble, and has a longer service life.

[0108] In some embodiments of the present invention, the connecting disc 43, the inner barrel 20, and the sealing disc 44 are integrally formed. Therefore, this integral structure not only ensures the structural and performance stability of the connecting disc 43, the inner barrel 20, and the sealing disc 44, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the connecting disc 43, the inner barrel 20, and the sealing disc 44, and ensuring the reliability of their connection. Moreover, the integrally formed structure has higher overall strength and stability, is easier to assemble, and has a longer service life.

[0109] In some embodiments of the present invention, the connecting disc 43 and the sealing disc 44 are integrally formed parts, while the connecting disc 43 and the inner barrel 20 are separately processed parts. Thus, the integral structure not only ensures the structural and performance stability of the connecting disc 43 and the sealing disc 44, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the connecting disc 43 and the sealing disc 44 and ensuring the reliability of the connection between the connecting disc 43 and the sealing disc 44. Moreover, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0110] In some embodiments of the present invention, the connecting disc 43 and the sealing disc 44 are detachably connected. Since the sealing disc 44 is in a stop-fitting relationship with the first seal 42, there is a risk of wear on the sealing disc 44 after long-term use. By making the connecting disc 43 and the sealing disc 44 detachably connected, it is convenient to disassemble and assemble the sealing disc 44 to facilitate the maintenance and replacement of the sealing disc 44.

[0111] Specifically, for example, the sealing disc 44 includes a sealing disc peripheral wall and a sealing disc bottom wall. The sealing disc peripheral wall extends in the axial direction of the dehydration shaft 31 into a cylindrical shape and is arranged around the dehydration shaft 31. The sealing disc peripheral wall is spaced apart from the dehydration shaft 31. The sealing disc bottom wall is located on the side of the sealing disc peripheral wall adjacent to the inner tub 20. The sealing disc bottom wall has a through hole for the washing shaft 32 to pass through. The first sealing member 42 abuts against the outer peripheral surface of the sealing disc peripheral wall. A third sealing member 45 is provided between the sealing disc bottom wall and the connecting disc 43.

[0112] Optionally, the dehydration shaft 31 is connected to the bottom wall of the sealing disc, and the dehydration shaft 31 passes through the bottom wall of the sealing disc and is connected to the connecting disc 43.

[0113] In some embodiments of the present invention, the third sealing element 45 includes a flexible substrate and a metal sheet embedded within the flexible substrate. Therefore, not only can the sealing effect of the third sealing element 45 be improved by utilizing the flexible substrate, but the metal sheet embedded within the flexible substrate also helps to improve the structural strength of the third sealing element 45, thereby increasing the service life of the third sealing element 45.

[0114] The installation scheme of the garment processing device 100 in this embodiment of the invention is as follows: Using the outer tub 10 as the carrier and reference, firstly, the second sealing element 53 is installed on the limiting groove 54 of the water receiving box 50. Then, the water receiving box 50 and the second sealing element 53 are installed together in the insertion groove 17. The water receiving box 50 is fixed to the bottom of the outer tub 10 by screwing. Then, the clutch 30 is installed. Next, the sealing disc 44 and the third sealing element 45 are sequentially installed on the dehydration shaft 31 of the clutch 30. Then, the first sealing element 42 is first fitted onto the sealing disc 44. The sealing rib 422 of the first sealing element 42 is aligned and pressed into the sealing groove 13 of the outer tub 10. It is then fixed to the outer tub 10 by screwing. The sealing disc 44 and the first sealing element 42 form a moving seal. The sealing mechanism is as follows: (the sealing disc 44 rotates synchronously with the dehydration shaft 31, the connecting disc 43, and the inner tub 20, while the first sealing element 42 remains relatively stationary with respect to the outer tub 10). The connecting disc 43 is screwed into the inner tub 20, and the connecting disc 43, the third sealing element 45, the sealing disc 44, and the dehydration shaft 31 are also screwed into the connecting disc 43. Since the third sealing element 45 is made of a metal skeleton and rubber, with the rubber having an internal metal skeleton, there are sealing elements between the connecting disc 43 and the inner tub 20, and between the clutch 30 and the outer tub 10. Therefore, a sealed drainage channel 41 is formed between the inner tub 20, the connecting disc 43, the first sealing element 42, the sealing disc 44, the third sealing element 45, the outer tub 10, the water receiving tray, the clutch 30, and the drain valve 60.

[0115] In some embodiments of the present invention, such as Figure 26 As shown, a drain valve 60 is connected to the drain port 57 of the water receiving box 50. Specifically, when the clothes handling equipment 100 is in the washing process, the drain valve 60 can be controlled to be closed, and when the clothes handling equipment 100 is in the spin-drying state, the drain valve 60 can be controlled to be opened, thereby achieving the purpose of draining.

[0116] In some embodiments of the present invention, such as Figure 26 As shown, the garment handling device 100 may include a three-way pipe 61 and a water level detection device. The water level detection device includes an air chamber 62 and a pressure detection unit. The air chamber 62 may be located on the outer peripheral wall of the outer tub 10. The first port of the three-way pipe 61 is connected to the drain port 57, and the second port of the three-way pipe 61 is connected to a drain valve 60. The air chamber 62 is connected to the pressure detection unit via the third port of the three-way pipe 61. For example, the pressure detection unit can be a water level sensor. It is understood that when water from the drain channel 41 enters the third port of the three-way pipe 61, this water acts on the air chamber 62, and the pressure detection unit detects the presence of water, thus facilitating the detection of the water level in the inner tub 20.

[0117] In some embodiments of the present invention, the air chamber 62 is integrally formed on the outer peripheral wall of the outer barrel 10. This not only simplifies the structure but also eliminates the need for a separate air chamber 62, reducing installation costs and improving the connection strength between the air chamber 62 and the outer barrel 10.

[0118] In some embodiments of the present invention, the air chamber 62 is connected to the third port via a transfer pipe 63 and an intermediate pipe 64. This results in a simple structure.
