Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically relating to an outer tub, tub assembly, and clothing processing equipment for clothing processing. Background Technology

[0002] Clothing processing equipment generally includes an outer tub and an inner tub. The outer tub is mainly used to hold the washing water and connect to the drain pipe for drainage, while the inner tub is mainly used to hold the clothes and work with the impeller or agitator to wash and spin-dry the clothes.

[0003] In existing garment processing equipment designs, the outer tub is typically equipped with an overflow chamber to drain excess water during operation, preventing water from overflowing from the top edge of the tub and damaging electrical components. For example, Chinese invention patent application number CN202010185367.0 discloses a washing machine.

[0004] However, the overflow port at the bottom of the overflow chamber on the outer tub is usually circular. To ensure sufficient overflow flow, the overflow chamber needs to protrude outwards by a sufficient distance. When the washing machine is unbalanced or overloaded, the end of the overflow chamber is prone to colliding with the side wall of the casing. In particular, as washing machines have become increasingly larger in capacity, the distance between the outer tub and the casing has decreased to achieve a more compact structure, making the collision even more severe.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] This invention provides an outer tub for a garment processing device. By setting the width of the overflow outlet in the convex direction of the overflow cavity to be smaller than the width of the overflow outlet in the convex direction perpendicular to the overflow cavity, the outward protrusion distance of the overflow cavity can be reduced without reducing the flow area of ​​the overflow outlet, thus solving the problem that the overflow cavity on the existing outer tub is prone to colliding with the box body.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] An outer tub of a garment processing device, wherein an overflow cavity protruding outward is provided on the outer tub, and an overflow port is provided at the bottom of the overflow cavity;

[0009] The width of the overflow outlet in the convex direction of the overflow cavity is smaller than the width of the overflow outlet in the convex direction perpendicular to the overflow cavity.

[0010] Furthermore, the overflow cavity protrudes outward along the radial direction of the outer barrel, and the maximum width direction of the overflow port is perpendicular to the protrusion direction of the overflow cavity;

[0011] Preferably, the overflow outlet is elliptical, and the direction of the maximum width of the overflow outlet is the direction of the extension of the major axis of the ellipse; or, the overflow outlet is rhomboid, and the direction of the maximum width of the overflow outlet is the direction of the extension of the longer diagonal of the rhomboid.

[0012] Furthermore, the end face of the overflow cavity extends along the edge of the overflow port on the side away from the outer barrel axis;

[0013] Preferably, the overflow port is elliptical, and the end face of the overflow cavity is a curved surface extending along the side of the overflow port away from the axis of the outer barrel.

[0014] Furthermore, the width of the overflow cavity gradually decreases in the direction away from the axis of the outer barrel, and the left and right sidewalls of the overflow cavity are set as inclined surfaces that smoothly transition to the two ends of the overflow cavity end face. The angle between the left and right sidewalls of the overflow cavity and the convex direction of the overflow cavity is greater than or equal to 45°.

[0015] Furthermore, the width of the overflow outlet in the protruding direction perpendicular to the overflow cavity is 1.2 to 2 times the width of the overflow outlet in the protruding direction of the overflow cavity.

[0016] Furthermore, the bottom of the overflow chamber is provided with an overflow connector extending downward from the edge of the overflow port, and the overflow connector is spaced apart from the outer side wall of the outer barrel.

[0017] Preferably, the overflow port and the cavity wall near the outer barrel axis are spaced apart, and the overflow connector extends vertically downward from the edge of the overflow port.

[0018] Furthermore, the cavity wall of the overflow cavity on the side near the axis of the outer barrel extends vertically upward from the bottom of the overflow cavity on the side near the axis of the outer barrel, and the top of the cavity wall of the overflow cavity on the side near the axis of the outer barrel is lower than the top of the outer barrel; multiple upward-extending baffles are provided on the top of the cavity wall of the overflow cavity on the side near the axis of the outer barrel, and the multiple baffles are arranged at intervals along the circumference of the outer barrel.

[0019] Preferably, a reinforcing rib is provided on the side of the baffle away from the axis of the outer barrel, and the lower end of the reinforcing rib extends to the bottom of the overflow cavity.

[0020] The present invention also provides a tub assembly for a garment processing device, including an outer tub of the garment processing device, an outer tub cover installed on the top of the outer tub, and a shielding part provided on the outer tub cover corresponding to the top of the overflow chamber.

[0021] Preferably, the lower end of the outer barrel cover is inserted into the top of the outer barrel, and the bottom of the shielding part is inserted into the upper end of the overflow cavity.

[0022] Furthermore, the outer barrel cover is provided with multiple sets of first snap-fit ​​structures arranged circumferentially, each set of first snap-fit ​​structures including two that are close to each other, and the blocking part is disposed between the two first snap-fit ​​structures in one set of first snap-fit ​​structures;

[0023] The outer barrel is equipped with a second snap-fit ​​structure that snaps into the first snap-fit ​​structure one by one.

[0024] The present invention also provides a garment processing device, wherein a drum assembly of the above-mentioned garment processing device is installed;

[0025] Preferably, the overflow pipe of the garment processing equipment is fitted onto the overflow connector at the bottom of the overflow chamber.

[0026] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0027] 1. By setting the width of the overflow port in the convex direction of the overflow cavity to be smaller than the width of the overflow port in the convex direction perpendicular to the overflow cavity, the present invention can reduce the outward protrusion distance of the overflow cavity without reducing the flow area of ​​the overflow port. This is beneficial to improving the compactness of the garment processing equipment structure and reducing the occurrence of barrel collisions.

[0028] 2. By setting the overflow port to an ellipse and making the end face of the overflow cavity a curved surface extending along the side of the overflow port away from the outer barrel axis, the present invention can further reduce the distance of the overflow cavity protruding outward.

[0029] 3. By setting the width of the overflow port to 1.2 to 2 times that of the overflow cavity in the convex direction, the present invention can avoid excessive curvature at both ends of the elliptical overflow port, that is, it can avoid the elliptical overflow port being too flat, and can ensure the connection effect between the overflow pipe and the overflow connector, and prevent water from leaking from the gap between the overflow pipe and the overflow connector.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] This invention provides a garment processing device, specifically a pulsator-type garment processing device, which includes a housing, an inner tub, and an outer tub coaxially sleeved outside the inner tub. The outer tub is suspended in the housing by a shock-absorbing device.

[0049] In this embodiment, the clothing processing equipment can be a pulsator washing machine or a pulsator washer-dryer combo.

[0050] Example 1

[0051] like Figures 1 to 5 As shown in the figure, an outer tub 1 of a garment processing device is disclosed in an embodiment of the present invention. The outer tub 1 is provided with an overflow cavity 101. The overflow cavity 101 protrudes outward from the top of the side wall of the outer tub 1. The bottom of the overflow cavity 101 is provided with an overflow port 1014. The overflow port 1014 is used to connect to the overflow pipe of the garment processing device.

[0052] In some specific embodiments, the overflow cavity 101 includes a first cavity wall 1011 disposed on the side of the overflow cavity 1 away from the axis of the outer barrel 1, a second cavity wall 1012 disposed on the side of the overflow cavity 101 close to the axis of the outer barrel 1, and a third cavity wall 1013 connected to the bottom of the first cavity wall 1011 and the second cavity wall 1012, which closes the bottom of the overflow cavity 101. The overflow port 1014 is disposed at the bottom of the overflow cavity 101, that is, the overflow port 1014 is opened on the third cavity wall 1013 of the overflow cavity 101.

[0053] Specifically, such as Figure 2 and Figure 3As shown, in this embodiment, the overflow cavity 101 protrudes horizontally from the top of the side wall of the outer barrel 1 in a direction away from the axis of the outer barrel 1, forming the first cavity wall 1011 and the third cavity wall 1013 of the overflow cavity 101. The second cavity wall 1012 of the overflow cavity 101 protrudes upward from the side of the third cavity wall 1013 near the axis of the outer barrel 1. The left and right sides of the third cavity wall 1013 are connected to the left and right sides of the first cavity wall 1011, forming an overflow cavity 101 with an open top.

[0054] Preferably, in this embodiment, the inner wall of the second cavity wall 1012 is coplanar with the inner walls of the outer barrel 1 on both sides of the overflow cavity 101.

[0055] Preferably, in this embodiment, the width of the overflow port 1014 in the protruding direction of the overflow cavity 101 is smaller than the width of the overflow port 1014 in the protruding direction perpendicular to the overflow cavity 101. Therefore, while ensuring that the flow area of ​​the overflow port 1014 is not reduced, the outward protrusion distance of the overflow cavity 101 can be reduced, which is beneficial to improving the compactness of the garment processing equipment structure and reducing the occurrence of collisions with the drum.

[0056] In this embodiment, the first cavity wall 1011 of the overflow cavity 101 protrudes outward along the radial direction of the outer barrel 1, and the width of the first cavity wall 1011 of the overflow cavity 101 gradually decreases along the direction away from the axis of the outer barrel 1.

[0057] The statement that "the width of the overflow port 1014 in the convex direction of the overflow cavity 101 is less than the width of the overflow port 1014 in the convex direction perpendicular to the overflow cavity 101" specifically means that the width of the overflow port 1014 in the convex direction of the first cavity wall 1011 is less than the width of the overflow port 1014 in the convex direction perpendicular to the first cavity wall 1011.

[0058] With the above settings, the shape of the overflow port 1014 is more adapted to the shape of the third cavity wall 1013 of the overflow cavity 101, that is, the shape of the bottom of the overflow cavity 101. Thus, the area of ​​the overflow port 1014 can be guaranteed, and the size of the first cavity wall 1011 of the overflow port 1014 protruding away from the axis of the outer tub 1 can be reduced, thereby reducing the overall size of the outer tub 1 and improving the compactness of the assembly between the housing and the outer tub 1 of the clothing processing equipment.

[0059] In this embodiment, the overflow port 1014 can be polygonal or elliptical.

[0060] Preferably, in this embodiment, the maximum width direction of the overflow port 1014 is perpendicular to the protrusion direction of the overflow cavity 101, and the minimum width direction of the overflow port 1014 is consistent with the protrusion direction of the overflow cavity 101.

[0061] Preferably, the third cavity wall 1013 of the overflow cavity 101 is axially symmetric. In the horizontal direction, the axis of symmetry of the third cavity wall 1013 intersects the axis of the outer barrel 1, and the minimum width direction of the overflow port 1014 coincides with the axis of symmetry of the third cavity wall 1013.

[0062] In some possible embodiments, the overflow port 1014 is configured as a rhombus, with the maximum width direction of the overflow port 1014 being the extension direction of the longer diagonal of the rhombus, and the minimum width direction of the overflow port 1014 being the extension direction of the shorter diagonal of the rhombus.

[0063] In some other possible embodiments, the overflow port 1014 is elliptical, with the maximum width direction of the overflow port 1014 being the extension direction of the major axis of the ellipse, the minimum width direction of the overflow port 1014 being the extension direction of the minor axis of the ellipse, and the minor axis of the ellipse perpendicularly bisecting the major axis of the ellipse.

[0064] Preferably, in this embodiment, the overflow port 1014 is set to an elliptical shape, which facilitates the connection of the overflow port 1014 to the overflow pipe of the clothing processing equipment and helps to improve the sealing performance.

[0065] Specifically, in this embodiment, the bottom of the overflow cavity 101 is provided with an overflow connector 1015 extending downward from the edge of the overflow port 1014, and the overflow connector 1015 is spaced apart from the outer side wall of the outer barrel 1. Therefore, when connecting the overflow pipe, the end of the overflow pipe can be sleeved on the overflow connector 1015, and then fixed by pipe clamps, buckles, or other structures. At the same time, changing the overflow port 1014 from a circle to an ellipse ensures the compatibility between the overflow pipe and the overflow connector 1015. Specifically, even if the cross-section of the overflow pipe is circular, a stable connection with the overflow connector 1015 can still be achieved.

[0066] In this embodiment, the cross-sectional area of ​​the overflow connector 1015 can be the same as the area of ​​the overflow port 1014, or it can be smaller than the area of ​​the overflow port 1014.

[0067] Preferably, in this embodiment, the overflow port 1014 and the cavity wall of the overflow chamber 101 near the axis of the outer barrel 1 are spaced apart, and the overflow connector 1015 extends vertically downward from the edge of the overflow port 1014. The cross-sectional area of ​​the overflow connector 1015 is the same as the area of ​​the overflow port 1014, thereby ensuring the consistency of the cross-sectional area of ​​the overflow connector 1015 and ensuring the drainage performance of the overflow connector 1015.

[0068] In this embodiment, the overflow port 1014 can be located in the middle of the third cavity wall 1013 of the overflow cavity 101.

[0069] In some preferred embodiments, the end face of the overflow cavity 101 extends along the edge of the overflow port 1014 away from the axis of the outer barrel 1. Specifically, the overflow port 1014 is elliptical, and the end face of the overflow cavity 101 is a curved surface extending along the overflow port 1014 away from the axis of the outer barrel 1.

[0070] like Figure 2 As shown, in this embodiment, the third cavity wall 1013 is configured as a triangular structure, and the overflow port 1014 is opened on the third cavity wall 1013 and located at one end of the third cavity wall 1013 away from the axis of the outer barrel 1. The overflow port 1014 is elliptical, and there is a gap between the side of the overflow port 1014 near the axis of the outer barrel 1 and the edge of the third cavity wall 1013 near the axis of the outer barrel 1, so that the operator can connect the overflow pipe to the overflow connector 1015.

[0071] The long axis of the overflow port 1014 extends perpendicularly to the protruding direction of the overflow cavity 101. The end of the third cavity wall 1013, i.e., the end of the third cavity wall 1013 away from the axis of the outer barrel 1, extends along the side of the overflow port 1014 away from the axis of the outer barrel 1, and is curved. The first cavity wall 1011 extends vertically upward from the edge of the outer side wall of the outer barrel 1, protruding from the third cavity wall 1013.

[0072] Preferably, in this embodiment, the third cavity wall 1013 extends in the horizontal direction.

[0073] In this embodiment, the left and right sidewalls of the overflow cavity 101 are configured as inclined surfaces that smoothly transition to both ends of the end face of the overflow cavity 101. That is, the first cavity wall 1011 of the overflow cavity 101 includes a curved surface corresponding to the end of the third cavity wall 1013 and inclined surfaces corresponding to the left and right sides of the third cavity wall 1013. The inclined surfaces smoothly transition to the curved surfaces from both ends of the curved surfaces, and the ends of the inclined surfaces are integrated with the outer barrel 1 walls on both sides of the overflow cavity 101.

[0074] Preferably, in this embodiment, the angle between the left and right sidewalls of the overflow cavity 101 and the protruding direction of the overflow cavity 101 is greater than or equal to 45°, thereby ensuring that there is sufficient area on the third cavity wall 1013 for the overflow port 1014 to be arranged.

[0075] Preferably, in this embodiment, the width of the overflow port 1014 in the protruding direction perpendicular to the overflow cavity 101 is 1.2 to 2 times the width of the overflow port 1014 in the protruding direction of the overflow cavity 101. That is, the ratio between the length of the major axis and the length of the minor axis of the elliptical overflow port 1014 is 1.2 to 2. This avoids excessive curvature at both ends of the elliptical overflow port 1014, that is, it avoids the elliptical overflow port 1014 from being too flat, and ensures the connection effect between the overflow pipe and the overflow connector 1015, preventing water from leaking from the gap between the overflow pipe and the overflow connector 1015.

[0076] In this embodiment, the cavity wall of the overflow cavity 101 near the axis of the outer tub 1 extends vertically upward from the bottom of the overflow cavity 101 near the axis of the outer tub 1, and the top of the cavity wall of the overflow cavity 101 near the axis of the outer tub 1 is lower than the top of the outer tub 1. That is, the second cavity wall 1012 of the overflow cavity 101 extends vertically upward from the edge of the third cavity wall 1013 near the axis of the outer tub 1, and the upper edge of the second cavity wall 1012 is lower than the upper edge of the outer tub 1.

[0077] The top of the second cavity wall 1012 of the overflow cavity 101 is provided with a plurality of upwardly extending baffles 1016, which are arranged at intervals along the circumference of the outer barrel 1.

[0078] Preferably, the baffle 1016 is disposed in the middle of the top of the second cavity wall 1012, and an opening for water to flow out is formed at the interval between two adjacent baffles 1016 and between the baffle 1016 and the end of the first cavity wall 1011 of the overflow cavity 101.

[0079] In this embodiment, when the water level in the outer tub 1 continuously rises due to abnormal conditions such as a malfunction of the inlet valve in the clothing processing equipment, the water in the outer tub 1 can overflow from the top of the second cavity wall 1012 into the overflow chamber 101. Preferably, the end of the overflow pipe away from the overflow connector 1015 is connected to the drain pipe of the clothing processing equipment. The water flowing into the overflow chamber 101 can be discharged to the drain pipe through the overflow port 1014 and the overflow pipe, preventing the overflowing water from splashing onto the electrical components installed on the base of the clothing processing equipment, thus improving the safety of the clothing processing equipment.

[0080] Preferably, in this embodiment, a reinforcing rib 1017 is provided on the side of the baffle 1016 away from the axis of the outer barrel 1, and the lower end of the reinforcing rib 1017 extends to the bottom of the overflow cavity 101.

[0081] Specifically, the baffle 1016 is a plate with a certain width and thickness. The width direction of the baffle 1016 corresponds to the circumferential direction of the outer barrel 1, and the thickness direction of the baffle 1016 corresponds to the radial direction of the outer barrel 1. Preferably, the thickness of the baffle 1016 and the thickness of the second cavity wall 1012 are consistent with the thickness of the outer barrel 1 wall.

[0082] The reinforcing rib 1017 protrudes outward from the center of the side of the baffle 1016 away from the axis of the outer barrel 1. The upper end of the reinforcing rib 1017 extends to be flush with the top of the baffle 1016, and the lower end of the reinforcing rib 1017 extends vertically downward along the second cavity wall 1012, connecting to the top of the third cavity wall 1013. This ensures the strength of the second cavity wall 1012 and the baffle 1016, preventing the baffle 1016 from breaking.

[0083] Preferably, in this embodiment, the cross-sectional area of ​​the reinforcing rib 1017 gradually increases from top to bottom.

[0084] Preferably, in this embodiment, the upper edge of the first cavity wall 1011 is flush with the upper edge of the outer barrel 1.

[0085] In this embodiment, an outer bucket cover 2 is installed on the top of the outer bucket 1. The outer bucket cover 2 is provided with a shielding part 1018 corresponding to the top of the overflow cavity 101. The shielding part 1018 corresponds to the top opening of the overflow cavity 101 and is used to close the top opening of the overflow cavity 101.

[0086] Preferably, the lower end of the outer barrel cover 2 is inserted into the top of the outer barrel 1, and the bottom of the shielding part 1018 is inserted into the upper end of the overflow cavity 101. Thus, the operator can quickly determine the installation angle of the outer barrel cover 2 on the outer barrel 1 based on the relative positions of the shielding part 1018 and the overflow cavity 101, improving assembly efficiency and accuracy.

[0087] Specifically, the outer barrel cover 2 includes a cover body 20 and a support rib 22. The lower end of the cover body 20 is inserted into the top of the outer barrel 1, and the support rib 22 is provided on the outer side wall of the cover body 20 for abutting and limiting the position with the top of the outer barrel 1.

[0088] The support rib 22 is a ring structure. The support rib 22 protrudes outward at the position corresponding to the overflow cavity 101. The outward protruding part of the support rib 22 abuts against the top of the first cavity wall 1011. The shielding part 1018 is arranged above the support rib 22 and protrudes outward relative to the cover 20.

[0089] The bottom of the support rib 22 is provided with a downwardly extending insertion part, which is inserted into the top of the first cavity wall 1011.

[0090] Preferably, in this embodiment, the side of the baffle 1016 near the axis of the outer barrel 1 is coplanar with the inner wall of the outer barrel 1, and the lower end of the cover 20 extends below the upper end of the baffle 1016.

[0091] In this embodiment, the outer barrel cover 2 is provided with a plurality of first snap-fit ​​structures 21 arranged at intervals along the circumference, and the outer barrel 1 is provided with second snap-fit ​​structures 190 that snap-fit ​​one-to-one with the first snap-fit ​​structures 21. The snap-fit ​​of the first snap-fit ​​structures 21 and the second snap-fit ​​structures 190 realizes the pre-installation positioning of the outer barrel cover 2, and then the outer barrel cover 2 can be further fixed by screws or other structures.

[0092] In some preferred embodiments, the outer barrel cover 2 is provided with multiple sets of first snap-fit ​​structures 21 arranged circumferentially, each set of first snap-fit ​​structures 21 including two that are close to each other, and the blocking part 1018 is disposed between the two first snap-fit ​​structures 21 of one set of first snap-fit ​​structures 21.

[0093] In this embodiment, an inner bucket is coaxially sleeved inside the outer bucket 1, and the outer bucket cover 2 is used to cover the gap between the outer bucket 1 and the inner bucket.

[0094] Preferably, in this embodiment, the upper end of the overflow pipe of the clothing processing device is sleeved on the overflow connector 1015 at the bottom of the overflow chamber 101, and the lower end of the overflow pipe extends downward along the outer side wall of the outer tub 1 and communicates with the drain pipe of the clothing processing device. The overflow pipe is preferably a corrugated hose.

[0095] In some preferred embodiments, a limiting part 1019 is provided on the outer side wall of the outer barrel 1. The limiting part 1019 is C-shaped and extends radially along the outer barrel 1, and is provided near the bottom of the outer barrel 1. The limiting part 1019 is used to limit the lower end of the overflow pipe.

[0096] Example 2

[0097] The embodiments of the present invention are used to further describe the outer barrel cover 2 in the above embodiment one.

[0098] like Figures 6 to 10 The present invention discloses an outer tub cover 2, which is assembled with the outer tub 1 to cover the gap between the inner tub and the outer tub 1, thereby improving the overall aesthetics of the clothing processing equipment and preventing users from accidentally touching the high-speed rotating inner tub.

[0099] The outer barrel cover 2 includes a cover body 20, and the side wall of the cover body 20 is provided with a first snap-fit ​​structure 21 for snapping with the outer barrel 1.

[0100] In some specific embodiments, the outer barrel 1 is provided with a second snap-fit ​​structure 190 for cooperating with the first snap-fit ​​structure 21. When the outer barrel cover 2 is assembled with the outer barrel 1, the outer barrel cover 2 abuts against the top of the outer barrel 1, and the first snap-fit ​​structure 21 on the cover body 20 snaps with the second snap-fit ​​structure 190 on the side wall of the outer barrel 1, thereby fixing the outer barrel cover 2 to the outer barrel 1.

[0101] In this embodiment, the first snap-fit ​​structure 21 can be disposed on the inner side wall of the cover 20 or on the outer side wall of the cover 20. Preferably, in order to avoid mutual interference between the first snap-fit ​​structure 21 and the inner tub, the first snap-fit ​​structure 21 is disposed on the outer side wall of the cover 20, and the second snap-fit ​​structure 190 is disposed on the outer side wall of the outer tub 1, corresponding to the first snap-fit ​​structure 21.

[0102] Preferably, in this embodiment, the cover 20 is provided with a support surface 2220 for abutting against the top of the outer barrel 1. The first snap-fit ​​structure 21 is connected above the support surface 2220 and has a gap between it and the support surface 2220. Furthermore, the connection between the first snap-fit ​​structure 21 and the side wall of the cover 20 is offset from the support surface 2220 in the circumferential direction of the cover 20, so that the first snap-fit ​​structure 21 can undergo elastic deformation in the vertical direction.

[0103] By setting the connection between the first snap-fit ​​structure 21 and the side wall of the cover 20 above the support surface 2220 and providing a gap between them, it is beneficial to increase the deformation of the first snap-fit ​​structure 21 in the vertical direction during the snap-fit ​​process between the first snap-fit ​​structure 21 and the outer barrel 1, thus preventing the outer barrel cover 2 from wobbling up and down relative to the outer barrel 1 after installation.

[0104] Specifically, in existing technology, during the installation of the outer bucket lid, the first snap-fit ​​structure generally only undergoes deformation in a direction away from the lid's axis. When the support surface 2220 on the lid contacts the top of the outer bucket, the first snap-fit ​​structure springs back and snaps onto the second snap-fit ​​structure. This solution requires a margin for the first snap-fit ​​structure to mate with the second snap-fit ​​structure on the outer bucket. The vertical distance between the snap-fit ​​surface of the first snap-fit ​​structure and the support surface 2220 needs to be set to be greater than the vertical distance between the top surface of the outer bucket and the snap-fit ​​surface of the second snap-fit ​​structure.

[0105] Specifically, the engaging surface of the first engaging structure is the bottom of the card interface on the first engaging structure, and the engaging surface of the second engaging structure is the lower end face of the second engaging structure.

[0106] Because the deformation of the first snap-fit ​​structure under the pressure of the second snap-fit ​​structure is a rotational deformation in a direction away from the axis of the lid, the bottom of the snap-fit ​​interface on the first snap-fit ​​structure will move upward relative to the outer lid. Therefore, a certain margin needs to be set to ensure that when the support surface 2220 abuts against the top of the outer bucket, the bottom of the snap-fit ​​interface is flush with the lower end face of the second snap-fit ​​structure. However, after the first snap-fit ​​structure rebounds, the bottom of the snap-fit ​​interface of the first snap-fit ​​structure will be lower than the lower end face of the second snap-fit ​​structure, causing the outer lid to sway up and down relative to the outer bucket.

[0107] This application, by placing the connection between the first snap-fit ​​structure 21 and the side wall of the cover 20 above the support surface 2220 and providing a gap between them, facilitates increasing the vertical deformation of the first snap-fit ​​structure 21 during the snap-fit ​​process with the outer barrel 1. Specifically, when the support surface 2220 on the cover 20 abuts against the top of the outer barrel 1, there is a gap between the connection between the first snap-fit ​​structure 21 and the side wall of the cover 20 and the top of the outer barrel 1. Therefore, by pulling down the first snap-fit ​​structure 21... The lower end of the first snap-fit ​​structure 21 is deformed in the vertical direction, so that the snap-fit ​​interface 213 of the first snap-fit ​​structure 21 snaps into the bottom of the second snap-fit ​​structure 190. It is not necessary to set the vertical distance between the snap-fit ​​surface of the first snap-fit ​​structure 21 and the support surface 2220 to be greater than the vertical distance between the top surface of the outer barrel 1 and the snap-fit ​​surface of the second snap-fit ​​structure 190. This can prevent the outer barrel cover 2 from shaking up and down relative to the outer barrel 1 after installation, increase the tightness of the fit between the outer barrel cover 2 and the outer barrel 1, and improve the positioning effect of the outer barrel cover 2.

[0108] Preferably, in this embodiment, the vertical distance between the engaging surface of the first engaging structure 21 and the supporting surface 2220 is less than or equal to the vertical distance between the top surface of the outer barrel 1 and the engaging surface of the second engaging structure 190.

[0109] In this embodiment, when the vertical distance between the engaging surface of the first engaging structure 21 and the supporting surface 2220 is less than the vertical distance between the top surface of the outer barrel 1 and the engaging surface of the second engaging structure 190, the difference between the vertical distance between the top surface of the outer barrel 1 and the engaging surface of the second engaging structure 190, and the vertical distance between the engaging surface of the first engaging structure 21 and the supporting surface 2220, is less than or equal to the vertical distance between the connection point of the first engaging structure 21 and the side wall of the cover 20 and the supporting surface 2220.

[0110] In some specific embodiments, the side wall of the cover 20 is provided with a support rib 22 for abutting against the top of the outer barrel 1, and the bottom surface of the support rib 22 forms a support surface 2220.

[0111] In this embodiment, the cover 20 extends axially along the outer barrel cover 2, and the cover 20 is inserted into or sleeved with the top of the outer barrel 1. When the cover 20 is inserted into the top of the outer barrel 1, a supporting rib 22 for abutting against the top of the outer barrel 1 is provided on the outer peripheral wall of the cover 20; when the cover 20 is sleeved with the top of the outer barrel 1, a supporting rib 22 for abutting against the top of the outer barrel 1 is provided on the inner peripheral wall of the cover 20.

[0112] Preferably, in this embodiment, in order to facilitate the layout of the first snap-fit ​​structure 21 and the second snap-fit ​​structure 190, and to increase the installation stability of the outer barrel cover 2, the outer diameter of the cover body 20 is adapted to the inner diameter of the opening of the outer barrel 1, and a support rib 22 protruding outward along the radial direction of the cover body 20 is provided on the outer peripheral wall of the cover body 20.

[0113] In some possible embodiments, the first snap-fit ​​structure 21 and the support rib 22 are offset in the circumferential direction of the cover 20. That is, the support rib 22 is provided with a plurality of ribs arranged at intervals along the circumferential direction of the cover 20, and the first snap-fit ​​structure 21 is provided at the interval between two adjacent support ribs 22. The bottom surface of the support rib 22 is the support surface 2220.

[0114] In some other possible embodiments, the support rib 22 is an annular structure extending circumferentially along the cover 20, with at least a portion of the support rib 22 protruding upwards, and a first snap-fit ​​structure 21 connected to the upwardly protruding portion of the support rib 22. The bottom surface of the non-protruding portion of the support rib 22 forms the support surface 2220.

[0115] like Figure 6 and Figure 7 As shown, in this embodiment, the supporting rib 22 is an annular structure that protrudes radially outward from the outer wall of the cover 20 and extends circumferentially along the cover 20. The supporting rib 22 has an upwardly protruding portion 221. The first snap-fit ​​structure 21 is connected to the middle of the protruding portion 221, and a gap is formed between the bottom of the protruding portion 221 and the top of the outer barrel 1. Therefore, during the process of installing the outer barrel cover 2 onto the outer barrel 1, the protruding portion 221 can provide deformation of the first snap-fit ​​structure 21 in the vertical direction, allowing the first snap-fit ​​structure 21 to smoothly engage with the second snap-fit ​​structure 190. Furthermore, after the first snap-fit ​​structure 21 and the second snap-fit ​​structure 190 are engaged, the outer barrel cover 2 is prevented from wobbling up and down relative to the outer barrel 1, improving the positioning effect of the outer barrel cover 2.

[0116] Specifically, in this embodiment, the supporting rib 22 includes a supporting rib body 222 and a protrusion 221, which together form a ring-shaped supporting rib 22. The protrusion 221 includes a first protruding segment 2211 and a second protruding segment 2212. The first protruding segment 2211 extends horizontally and is higher than the supporting rib body 222. The second protruding segment 2212 extends downward at an angle from both ends of the first protruding segment 2211 and connects to the supporting rib body 222.

[0117] In the circumferential direction of the cover 20, the size of the first snap-fit ​​structure 21 is smaller than the size of the first protrusion 2211, and the first snap-fit ​​structure 21 is connected to the middle of the first protrusion 2211.

[0118] In some specific embodiments, the first snap-fit ​​structure 21 includes a main body portion 211 extending downward from the end of the first protruding section 2211, and a reinforcing portion 212 disposed at the left and right edges of the main body portion 211.

[0119] The main body 211 extends downward from the end of the first protruding section 2211 and is plate-shaped. A snap-fit ​​interface 213 is provided in the middle of the main body 211, and the second snap-fit ​​structure 190 snaps into the snap-fit ​​interface 213. The reinforcing part 212 protrudes from the left and right edges of the main body 211 in a direction away from the side wall of the cover 20 and is prismatic.

[0120] Preferably, the card interface 213 extends downward from the top of the main body 211.

[0121] In this embodiment, the second snap-fit ​​structure 190 protrudes outward from the outer side wall of the outer barrel 1, and the lower end of the main body 211 bends downward and extends away from the axis of the cover 20, improving the smoothness of the snap-fit. Preferably, the bend at the lower end of the main body 211 is located below the snap-fit ​​interface 213.

[0122] In some preferred embodiments, the top of the second snap-fit ​​structure 190 is configured as a slope extending downward in a direction away from the axis of the outer tub 1 to further improve the smoothness of the snap-fit. Preferably, the bottom of the second snap-fit ​​structure 190 is configured as a flat plane extending radially along the outer tub 1.

[0123] In some preferred embodiments, the angle between the reinforcing part 212 and the main body 211 is acute. This ensures that the protruding direction of the reinforcing part 212 is not perpendicular to the extending direction of the main body 211, making the first snap-fit ​​structure 21 more prone to elastic deformation. This improves the smoothness of installing the outer lid 2 and prevents the reinforcing part 212 from breaking during the assembly and disassembly of the outer lid 2.

[0124] In this embodiment, the "protrusion direction of the first snap-fit ​​structure 21 relative to the side wall of the cover 20" specifically refers to the protrusion direction of the reinforcing part 212 on the first snap-fit ​​structure 21.

[0125] Preferably, in this embodiment, the upper end of the reinforcing part 212 extends above the supporting rib 22 and is connected to the top of the supporting rib 22 and / or the side wall of the cover 20 above the supporting rib 22.

[0126] like Figure 7 As shown, in this embodiment, the reinforcing part 212 is disposed near the left and right edges of the main body part 211 and extends along the left and right edges of the main body part 211. The reinforcing part 212 is a protruding ridge that protrudes away from the outer barrel 1. The lower end of the reinforcing part 212 extends to be close to the lower end of the main body part 211. The upper end of the reinforcing part 212 bends and extends from the connection between the main body part 211 and the support rib 22 toward the outer barrel 1. The lower side of the portion of the reinforcing part 212 extending above the support rib 22 is connected to the top of the support rib 22. The end of the portion of the reinforcing part 212 extending above the support rib 22 is connected to the outer side wall of the outer barrel 1. Thus, the strength of the first snap-fit ​​structure 21 can be improved, and the first snap-fit ​​structure 21 can be prevented from breaking.

[0127] In this embodiment, the protrusions 221 are provided with a plurality of protrusions arranged at intervals along the circumference of the cover 20. Each protrusion 221 is connected to a first snap-fit ​​structure 21. The outer side wall of the outer barrel 1 is provided with the same number of second snap-fit ​​structures 190, and the second snap-fit ​​structures 190 correspond one-to-one with the first snap-fit ​​structures 21.

[0128] Preferably, at least two protrusions 221 are close to each other as a group, and the cover 20 is provided with multiple groups of protrusions 221 arranged at intervals along the circumference.

[0129] In this embodiment, in the circumferential direction of the cover 20, the distance between two adjacent protrusions 221 located in the same group is smaller than the distance between two adjacent groups of protrusions 221.

[0130] Specifically, in this embodiment, every two protrusions 221 are close to each other as a group, and an ear plate 23 is provided between the two protrusions 221 in the same group. The ear plate 23 protrudes radially along the cover 20.

[0131] Screw posts 191 are provided on the outer side wall of the outer barrel 1. Each screw post 191 corresponds to a lug portion 23 on the cover 20. The screw posts 191 are located at the top of the outer side wall of the outer barrel 1, and the bottom of the lug portion 23 abuts against the top of the screw post 191. By placing the lug portion 23 between two protrusions 221 in the same group, the positioning effect of the lug portion 23 can be improved, aligning the lug portion 23 with the screw post 191.

[0132] Preferably, in this embodiment, the ear plate portion 23 protrudes radially from the end of the support rib body 222 along the cover 20, and the top of the ear plate portion 23 is coplanar with the top of the support rib body 222. This ensures the connection strength of the ear plate portion 23 and improves the overall integrity and aesthetics of the outer barrel cover 2.

[0133] Preferably, four sets of the first locking structure 21 are provided, and the four sets of the first locking structure 21 are evenly arranged around the circumference of the cover 20, with each set corresponding to one of the four corners of the garment processing equipment's housing. Thus, the four corners of the housing provide space for the outer tub cover 2 to be disassembled and reassembled, facilitating assembly, maintenance, and replacement by the operator. Furthermore, during use, when the outer tub 1 becomes eccentric, the first locking structure 21, the second locking structure 190, and the ear plate 23 can be prevented from impacting the housing.

[0134] Preferably, the vertical line connecting the axis of the ear plate portion 23 and the axis of the outer barrel cover 2 coincides with the angle bisector of the corner of the box body, that is, the protruding direction of the ear plate portion 23 corresponds to the corner of the box body.

[0135] Preferably, the width of the ear plate portion 23 gradually decreases along the direction away from the axis of the outer barrel cover 2.

[0136] In some preferred embodiments, the first snap-fit ​​structure 21 connected to the same set of protrusions 221 is parallel to each other in the protrusion direction relative to the sidewall of the cover 20.

[0137] Preferably, the protruding direction of the reinforcing portion 212 on the first snap-fit ​​structure 21 on the protrusions 221 on both sides of the ear plate portion 23 is parallel to the protruding direction of the ear plate portion 23. This further improves the convenience of assembling and disassembling the outer lid 2. Specifically, the operator can easily remove the outer lid 2 from the four corners of the top of the box.

[0138] Preferably, in this embodiment, the extending direction of the two second snap-fit ​​structures 190 corresponding to the two first snap-fit ​​structures 21 in the same group is parallel to the extending direction of the ear plate portion 23 between the two first snap-fit ​​structures 21 in the same group.

[0139] Preferred, such as Figure 10 As shown, in this embodiment, the end of the support rib 22 located between two adjacent protrusions 221 is bent downwards, that is, the end of the support rib body 222 is bent downwards to form a limiting wall 2221 for fitting with the top of the outer tub 1. Therefore, on the one hand, the positioning effect between the outer tub cover 2 and the outer tub 1 can be improved; on the other hand, the strength of the support rib 22 can be increased, thereby improving the service life of the outer tub cover 2.

[0140] Preferably, the end of the support rib 22 located between two adjacent protrusions 221 is at least partially set as a plane, that is, the end of the support rib body 222 is at least partially set as a plane, and the top of the outer side wall of the outer barrel 1 is provided with a plane opposite to it. When the outer barrel cover 2 is installed on the top of the outer barrel 1, the end of the support rib body 222 and the downwardly extending limiting wall 2221 are in contact with the plane of the top of the outer side wall of the outer barrel 1, thereby ensuring the accuracy of the installation angle of the outer barrel cover 2.

[0141] In some preferred embodiments, the first snap-fit ​​structure 21 extends vertically downward from the middle of the protrusion 221, or the first snap-fit ​​structure 21 extends downward toward the axis of the cover 20. The lower end of the first snap-fit ​​structure 21 clamps the wall of the outer barrel 1 to further improve the stability between the outer barrel cover 2 and the outer barrel 1.
