Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically relating to an outer tub of a garment processing device, a tub assembly on which the outer tub of the garment processing device is installed, and a garment processing device on which the tub assembly is installed. Background Technology

[0002] In existing technology, a pulsator washing machine includes an inner tub, an outer tub, and a casing. The inner tub and the outer tub are concentrically fitted together and can rotate relative to each other. A reduction clutch is installed at the bottom of the outer tub to drive the washing and spin-drying of clothes. The outer tub is movably installed in the casing via shock-absorbing devices such as suspension rods. Specifically, there is a hanging hole at each of the four corners of the washing machine casing, and four hanging parts on the outer tub corresponding to the four corners of the casing. The upper end of the suspension rod connects to the hanging hole on the casing, and the lower end of the suspension rod connects to the hanging part, suspending the outer tub in the casing.

[0003] However, the mounting portion on the outer tub of the washing machine is designed as a cuboid structure protruding radially outward along the outer tub, as disclosed in Chinese invention patent application number CN202010185367.0. When the washing machine is unbalanced or overloaded, the cuboid mounting portion is prone to colliding with the side wall of the casing. Specifically, the two corners at the ends of the cuboid mounting portion are prone to colliding with the side wall of the casing.

[0004] In particular, as washing machines gradually become larger in capacity, the distance between the outer tub and the casing tends to decrease in order to make the washing machine structure more compact, which makes the problem of tub collision more serious.

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

[0006] The present invention provides an outer tub for a garment processing device. By having the ends of the two side facades of the hanging part extend at an angle towards the center of the hanging part, it can avoid the side wall of the box and solve the problem that the hanging part on the existing outer tub is prone to collision with the box.

[0018] Preferably, the width of the end of the second part is substantially equal to the inner diameter of the mounting opening.

[0019] Furthermore, a limiting groove is provided at the bottom of the hanging part around the hanging opening, and the limiting groove extends inclinedly from bottom to top and away from the axis of the outer barrel;

[0020] Preferably, the limiting groove extends along the extension direction of the shock absorption device.

[0021] Furthermore, an avoidance groove is provided on the outer side wall of the outer tub, the avoidance groove is located below the hanging part and extends in the same direction as the limiting groove; and / or, the bottom of the outer side wall of the outer tub below the hanging part extends downward and in a direction close to the axis of the outer tub.

[0022] Furthermore, a third reinforcing rib extending along the axial direction of the outer tub is provided between the upper and lower sides of the hanging part and the outer side wall of the outer tub, and the third reinforcing rib is provided near the edge of the hanging part.

[0023] The third reinforcing rib on the lower side of the hanging part protrudes outward from the outer side wall of the outer barrel along the edges of the first and second parts;

[0024] Preferably, the third reinforcing rib on the lower side of the mounting part protrudes to the corner between the side facade and the end face of the second part;

[0025] Preferably, the third reinforcing rib on the upper side of the hanging part protrudes outward from the outer side wall of the outer barrel along the edge of the first part to correspond to the end of the side facade of the first part.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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] Specifically, the garment processing equipment has a hanging hole at each of the four corners of the box, and four hanging parts on the outer wall of the outer tub corresponding to the four corners of the box. The upper end of the shock-absorbing device is connected to the hanging hole on the box, and the lower end of the shock-absorbing device is connected to the hanging part on the outer wall of the outer tub.

[0050] In this embodiment, the clothing processing equipment can be a pulsator washing machine or a pulsator washer-dryer combo.

[0051] Example 1

[0052] like Figures 1 to 2 As shown, in this embodiment of the invention, an outer tub 1 of a garment processing device is provided, and a hanging part 11 for connecting to the shock absorption device of the garment processing device is provided on the outer side wall of the outer tub 1.

[0053] In this embodiment, the width of the end of the hanging part 11 gradually decreases along the direction away from the axis of the outer barrel 1.

[0054] Specifically, the ends of the two side facades of the hanging part 11 are configured as inclined surfaces extending towards the center of the hanging part 11 in a direction away from the axis of the outer barrel 1.

[0055] In this embodiment, the "two side surfaces of the hanging part 11" specifically refer to the vertical or approximately vertical surfaces located on the left and right sides of the hanging part 11 in the circumferential direction of the outer barrel 1, that is, the two side surfaces of the hanging part 11 in the left and right direction.

[0056] In some specific embodiments, the hanging part 11 is a cuboid structure that protrudes outward from the outer side wall of the outer barrel 1, and has a top surface, a bottom surface, an end face disposed on the side of the hanging part 11 away from the axis of the outer barrel 1, and side faces disposed on the left and right sides of the hanging part 11.

[0057] In this embodiment, by setting the ends of the two side facades of the hanging part 11 as inclined surfaces extending towards the center of the hanging part 11 in a direction away from the axis of the outer tub 1, the side wall of the box can be avoided, thereby increasing the distance between the hanging part 11 and the side wall of the box. Specifically, the hanging part 11 on the existing outer tub 1 is generally set as a cuboid structure. When the clothing processing equipment is unbalanced or overloaded, the corners of the hanging part 11 are prone to collide with the side wall of the box. In this embodiment, setting the ends of the two side facades of the hanging part 11 as inclined surfaces extending towards the center of the hanging part 11 in a direction away from the axis of the outer tub 1 reduces the probability of collision with the tub, improves the user experience, and at the same time, helps to reduce the distance between the outer tub 1 and the box, improves the structural compactness of the clothing processing equipment, helps to reduce the size of the box, or helps to increase the diameter of the outer tub 1 without increasing the size of the box, thereby increasing the capacity of the clothing processing equipment.

[0058] Preferably, in this embodiment, the hanging part 11 extends radially away from the axis of the outer tub 1, and the angle between the end of the side face of the hanging part 11 and the extension direction of the hanging part 11 is greater than or equal to 30° and less than or equal to 60°.

[0059] That is, the end of the side facade of the hanging part 11 is inclined at 30° to 60° relative to the extension direction of the hanging part 11 towards the middle of the hanging part 11. In this way, while ensuring the strength of the hanging part 11, the distance between the hanging part 11 and the side wall of the box is reasonably increased, which can ensure the service life of the outer barrel 1.

[0060] In some preferred embodiments, the angle between the end of the side facade of the mounting part 11 and the extending direction of the mounting part 11 is greater than or equal to 45° and less than or equal to 60°.

[0061] Since the mounting part 11 generally corresponds to the corner of the box, and the angle between the mounting part 11 and the side wall of the box that forms the corner is 45°, this embodiment sets the end of the side facade of the mounting part 11 to be inclined at 45° to 60° relative to the extension direction of the mounting part 11 towards the middle of the mounting part 11, so that the end of the side facade of the mounting part 11 is parallel to the side wall of the box on the corresponding side, or inclined inward relative to the side wall of the box on the corresponding side, thereby further reducing the probability of the mounting part 11 colliding with the box.

[0062] Preferably, in this embodiment, the angle between the end of the side facade of the mounting part 11 and the extending direction of the mounting part 11 is 50°.

[0063] In some specific embodiments, the hanging part 11 includes a first part 111 and a second part 112 arranged sequentially along a direction away from the axis of the outer tub 1. The side facade of the first part 111 is substantially parallel to the extension direction of the hanging part 11. The second part 112 is disposed at the end of the first part 111. The side facade of the second part 112 extends obliquely from the left and right sides of the end face of the first part 111 toward the middle of the hanging part 11. The side facades of the first part 111 and the second part 112 together constitute the side facade of the hanging part 11, and the side facade of the second part 112 constitutes the "end of the side facade of the hanging part 11".

[0064] In this embodiment, the phrase "the side elevation of the first part 111 is substantially parallel to the extension direction of the mounting part 11" specifically means that the side elevation of the first part 111 is parallel to the extension direction of the mounting part 11, or that the side elevation of the first part 111 has an angle of less than 10° with the extension direction of the mounting part 11. The side elevation of the first part 111 may be inclined towards the middle of the mounting part 11 relative to the extension direction of the mounting part 11, or it may be inclined towards both sides of the mounting part 11 relative to the extension direction of the mounting part 11.

[0065] Preferably, the side profile of the first part 111 is parallel to the extension direction of the hanging part 11, or the side profile of the first part 111 extends obliquely toward the middle of the hanging part 11 relative to the extension direction of the hanging part 11, and the angle between the side profile of the first part 111 and the extension direction of the hanging part 11 is less than or equal to 10°, thereby ensuring the connection strength between the hanging part 11 and the outer wall of the outer barrel 1.

[0066] Preferably, in this embodiment, the side facade of the first part 111 and the side facade of the second part 112 are smoothly connected by a rounded chamfer, and the side facade of the second part 112 and the end face of the second part 112 are smoothly connected by a rounded chamfer, so that the stress is distributed to the entire mounting part 11 and stress concentration is avoided.

[0067] In this embodiment, the end of the second part 112 near the axis of the outer tub 1 coincides with the end of the first part 111 away from the axis of the outer tub 1, and the end face of the second part 112 constitutes the end face of the hanging part 11.

[0068] In some preferred embodiments, the end face of the second portion 112 is configured as a plane perpendicular to the extension direction of the mounting portion 11.

[0069] In some preferred embodiments, the left and right sides of the hanging part 11 are provided with first reinforcing ribs 12 that protrude radially outward along the outer barrel 1 and extend circumferentially along the outer barrel 1. The ends of the first reinforcing ribs 12 are connected to the side facades of the hanging part 11, and the outer side surface of the first reinforcing ribs 12 is smoothly connected to the ends of the side facades of the hanging part 11.

[0070] The first reinforcing rib 12 can enhance the strength of the hanging part 11. By providing a smooth transition connection between the outer side of the first reinforcing rib 12 and the end of the side facade of the hanging part 11, stress can be dispersed to the first reinforcing rib 12, thereby improving the service life of the outer tub 1.

[0071] Preferably, in this embodiment, the outer side of the end of the first reinforcing rib 12 connected to the mounting part 11 is coplanar with the end of the side facade of the mounting part 11.

[0072] Specifically, such as Figure 2 As shown, in this embodiment, along the direction close to the mounting part 11, the width of the first reinforcing rib 12 protruding outward gradually increases, and the end of the first reinforcing rib 12 connected to the mounting part 11 protrudes outward to be flush with the end of the first part 111.

[0073] Preferably, the outer surface of the first reinforcing rib 12 is configured as an inclined surface coplanar with the side elevation of the second part 112, or the outer surface of the end of the first reinforcing rib 12 away from the hanging part 11 is configured as a curved surface bent in a direction away from the axis of the outer barrel 1, and the outer surface of the end of the first reinforcing rib 12 near the hanging part 11 is configured as an inclined surface coplanar with the side elevation of the second part 112.

[0074] In this embodiment, the outer side of the first reinforcing rib 12 is the side of the first reinforcing rib 12 away from the axis of the outer barrel 1.

[0075] Preferably, in this embodiment, the top surface of the first reinforcing rib 12 is flush with the top surface of the hanging part 11, and the thickness of the first reinforcing rib 12 is less than the thickness of the hanging part 11. The "thickness" refers to the dimension along the axial direction of the outer barrel 1.

[0076] Preferably, in this embodiment, the outer wall of the outer barrel 1 is provided with multiple reinforcing ribs extending circumferentially along the outer barrel 1 and spaced apart along the axial direction of the outer barrel 1. The first reinforcing rib 12 covers the reinforcing ribs, that is, the side of the first reinforcing rib 12 closest to the axis of the outer barrel 1 coincides with the reinforcing rib.

[0077] Preferably, the thickness of the first reinforcing rib 12 is greater than the thickness of the reinforcing rib.

[0078] In this embodiment, the mounting opening 113 on the mounting part 11 is located in the middle of the mounting part 11, corresponding to the junction of the first part 111 and the second part 112.

[0079] In some preferred embodiments, the protruding length of the first portion 111 is greater than or equal to the protruding length of the second portion 112. The diameter of the mounting opening 113, which is perpendicular to the mounting portion 11, substantially coincides with the boundary line between the first portion 111 and the second portion 112.

[0080] In this embodiment, the "basic overlap" specifically means that the diameter of the hanging opening 113 perpendicular to the hanging part 11 coincides with the dividing line between the first part 111 and the second part 112, or that it deviates from the dividing line between the first part 111 and the second part 112 by less than 2mm in a direction closer to or further away from the axis of the outer barrel 1.

[0081] In this embodiment, a second reinforcing rib 13 extending axially along the outer barrel 1 is provided on the upper side of the hanging part 11. The second reinforcing rib 13 is disposed on the left and right sides of the hanging opening 113, with the two second reinforcing ribs 13 arranged opposite to each other. The second reinforcing rib 13 protrudes outward from the outer side wall of the outer barrel 1 along the extending direction parallel to the hanging part 11 to correspond to the end of the side facade of the second part 112. This improves the strength of the hanging part 11 and prevents it from breaking.

[0082] Specifically, the length of the second reinforcing rib 13 protruding outward gradually decreases in the direction away from the hanging part 11, and the lower end of the second reinforcing rib 13 is integrally connected with the top surface of the hanging part 11. The lower end of the second reinforcing rib 13 extends to be substantially flush with the side of the hanging opening 113 away from the axis of the outer barrel 1.

[0083] In some possible embodiments, in the extending direction of the hanging part 11, the distance between the lower end of the second reinforcing rib 13 and the side of the hanging opening 113 away from the axis of the outer barrel 1 is less than or equal to 2 mm.

[0084] In some preferred embodiments, the lower end of the second reinforcing rib 13 is flush with the side of the hanging opening 113 away from the axis of the outer barrel 1.

[0085] Preferably, in this embodiment, the width of the end of the second part 112 is substantially equal to the inner diameter of the mounting opening 113.

[0086] like Figure 2 As shown, in this embodiment, a third reinforcing rib 14 extending along the axial direction of the outer barrel 1 is provided between the upper and lower sides of the hanging part 11 and the outer side wall of the outer barrel 1. The third reinforcing rib 14 is provided near the edge of the hanging part 11.

[0087] In this embodiment, the third reinforcing ribs 14 on the upper and lower sides of the hanging part 11 are all located near the left and right sides of the hanging part 11 and extend outward from the left and right sides of the hanging part 11 away from the axis of the outer tub 1. The third reinforcing rib 14 on the upper side of the hanging part 11 protrudes outward from the outer side wall of the outer tub 1 along the edge of the first part 111 to correspond to the end of the side facade of the first part 111. The third reinforcing rib 14 on the lower side of the hanging part 11 protrudes outward from the outer side wall of the outer tub 1 along the edges of the first part 111 and the second part 112.

[0088] Specifically, the lower end of the third reinforcing rib 14 on the upper side of the hanging part 11 is connected to the top surface of the hanging part 11. The lower end of the third reinforcing rib 14 on the upper side of the hanging part 11 extends to correspond to the end of the side facade of the first part 111. The upper end of the third reinforcing rib 14 on the upper side of the hanging part 11 extends to be close to the opening of the outer barrel 1. The width of the third reinforcing rib 14 protruding outward from the upper side of the hanging part 11 gradually decreases from bottom to top.

[0089] In this embodiment, two third reinforcing ribs 14 located on the upper side of the mounting part 11 are arranged opposite to each other, and a fourth reinforcing rib 15 extending circumferentially along the outer barrel 1 is provided between them. The fourth reinforcing rib 15 protrudes outward from the outer side wall of the outer barrel 1, and its two ends are respectively connected to the third reinforcing ribs 14 on both sides. Preferably, the width of the outward protrusion of the fourth reinforcing rib 15 gradually increases along the direction close to the third reinforcing rib 14.

[0090] Preferably, the fourth reinforcing rib 15 is provided with a plurality of ribs spaced apart along the axial direction of the outer barrel 1, and the upper end of the second reinforcing rib 13 is connected to the lower side of the fourth reinforcing rib 15 located at the bottom.

[0091] Preferably, in this embodiment, the third reinforcing rib 14 on the lower side of the mounting part 11 protrudes to the corner between the side facade and the end face of the second part 112.

[0092] Specifically, in this embodiment, the end of the hanging part 11 is provided with an opening 114 extending from the end of the hanging part 11 toward the axis of the outer barrel 1. The opening 114 is connected to the hanging port 113 and is used to allow the shock absorption device to be installed in the hanging port 113.

[0093] The width of the opening 114 is greater than or equal to the diameter of the suspension rod of the shock absorber, and the width of the opening 114 is less than the diameter of the mounting opening 113.

[0094] The upper end of the third reinforcing rib 14 on the lower side of the mounting part 11 is integrated with the bottom surface of the mounting part 11.

[0095] In this embodiment, the gap between the lower side of the mounting part 11 and the ends of the third reinforcing ribs 14 corresponding to the left and right edges gradually increases from top to bottom, which facilitates the installation and removal of the shock absorption device.

[0096] In some possible embodiments, the shock-absorbing device is any shock-absorbing rod assembly in the prior art. The upper end of the shock-absorbing rod assembly is connected to the housing, and the lower end of the shock-absorbing rod assembly is installed at the mounting port 113 through the opening 114.

[0097] In some specific embodiments, the shock-absorbing device includes a suspension rod, a shock-absorbing sleeve fitted onto the first end of the suspension rod, and a mating part disposed on the second end of the suspension rod. A base is fitted onto the end of the suspension rod inside the shock-absorbing sleeve, and the base slides in contact with the inner circumferential wall of the shock-absorbing sleeve. A buffer device is disposed inside the shock-absorbing sleeve, fitted onto the suspension rod, with one end of the buffer device abutting against the base and the other end abutting against the inner wall of the shock-absorbing sleeve. The buffer device may be a spring.

[0098] The housing is provided with a rod mounting seat, which has a hanging hole. The rod passes through the hanging hole and is matched with the rod mounting seat through a mating part.

[0099] In this embodiment, one end of the suspension rod with a shock-absorbing sleeve is hung on the mounting part 11. Specifically, the suspension rod enters the mounting opening 113 from the opening 114 of the mounting part 11, the outer diameter of the shock-absorbing sleeve is larger than the inner diameter of the mounting opening 113, and the shock-absorbing sleeve abuts against the bottom of the mounting part 11.

[0100] Preferably, the bottom of the mounting part 11 is provided with a limiting groove 1131 around the mounting opening 113, and the upper end of the shock-absorbing sleeve is disposed in the limiting groove 1131.

[0101] In some preferred embodiments, the top of the shock-absorbing sleeve is configured as a hemispherical surface, and the inner wall of the limiting groove 1131 is fitted with the upper end of the shock-absorbing sleeve.

[0102] Preferably, in this embodiment, the limiting groove 1131 extends obliquely from bottom to top in a direction away from the axis of the outer tub 1. On the one hand, since the extension direction of the shock-absorbing device is obliquely extended from bottom to top in a direction away from the axis of the outer tub 1, setting the limiting groove 1131 to extend obliquely from bottom to top in a direction away from the axis of the outer tub 1 can match the extension direction of the shock-absorbing device and ensure the limiting effect on the shock-absorbing sleeve. On the other hand, it can also reduce the recess depth of the limiting groove 1131 on the side away from the axis of the outer tub 1, so that the end of the hanging part 11 away from the axis of the outer tub 1 has sufficient wall thickness, thereby ensuring the strength of the end of the hanging part 11 away from the axis of the outer tub 1.

[0103] Preferably, in this embodiment, the limiting groove 1131 extends along the extending direction of the shock absorption device. Specifically, when the clothing processing equipment is not working, the extending direction of the hanging part 11 is consistent with the extending direction of the limiting groove 1131.

[0104] Preferably, an avoidance groove 16 is provided on the outer side wall of the outer tub 1. The avoidance groove 16 is located below the hanging part 11 and extends in the same direction as the limiting groove 1131; and / or, the bottom of the outer side wall of the outer tub 1 below the hanging part 11 extends downward and inclined towards the axis of the outer tub 1. This allows for avoidance of the shock-absorbing sleeve, ensuring the working stability of the shock-absorbing device on the one hand, and increasing the distance between the limiting groove 1131 and the end of the hanging part 11 on the other hand, thus ensuring the strength of the hanging part 11.

[0105] Preferably, in this embodiment, the width and / or depth of the clearance groove 16 gradually increase from top to bottom.

[0106] In some preferred embodiments, the hanging part 11 is disposed on the outer wall of the outer tub 1, close to the bottom of the outer tub 1.

[0107] Preferably, the third reinforcing rib 14 located on the lower side of the hanging part 11 and the part corresponding to the edge of the first part 111 extend downward to the bottom of the outer barrel 1.

[0108] Preferably, in this embodiment, the left and right sides of the third reinforcing rib 14 are provided with a sixth reinforcing rib 18 that protrudes outward from the outer side wall of the outer barrel 1 and extends along the circumference of the outer barrel 1. The width of the sixth reinforcing rib 18 protruding outward gradually decreases in the direction close to the third reinforcing rib 14, and one end of the sixth reinforcing rib 18 close to the third reinforcing rib 14 is connected to the outer side of the third reinforcing rib 14.

[0109] Preferably, at least one sixth reinforcing rib 18 is connected to the outer side of each third reinforcing rib 14 located on the upper side of the mounting part 11, and at least one sixth reinforcing rib 18 is connected to the outer side of each third reinforcing rib 14 located on the lower side of the mounting part 11.

[0110] Preferably, in this embodiment, a fifth reinforcing rib 17 is further provided on the upper side of the hanging part 11. The fifth reinforcing rib 17 is located on the side of the hanging opening 113 near the axis of the inner tub 3. The fifth reinforcing rib 17 protrudes outward from the outer side wall of the outer tub 1. The projection of the fifth reinforcing rib 17 on the horizontal plane coincides with the projection of the vertical line connecting the center of the hanging opening 113 and the axis of the outer tub 1 on the horizontal plane. The provision of the fifth reinforcing rib 17 can increase the strength of the hanging part 11 near the axis of the outer tub 1, and avoid the situation where the strength of the connection between the hanging part 11 and the outer tub 1 is reduced due to the inclined shape of the limiting groove 1131.

[0111] Preferably, the fifth reinforcing rib 17 has a cuboid structure, the lower end of the fifth reinforcing rib 17 is integrated with the top of the mounting part 11, and the upper end of the fifth reinforcing rib 17 is connected to the lower side of the fourth reinforcing rib 15 located at the bottom.

[0112] Preferably, in this embodiment, the outer wall of the outer tub 1 is provided with multiple rings of reinforcing ribs extending circumferentially and spaced apart axially along the outer tub 1. The first reinforcing rib 12, the fourth reinforcing rib 15, and the sixth reinforcing rib 18 are all disposed on the extension path of the reinforcing ribs. That is, the fourth reinforcing rib 15, disposed at different heights, is connected to a ring of reinforcing ribs, and the sixth reinforcing rib 18, disposed at different heights, is connected to a ring of reinforcing ribs, which helps to improve the overall strength of the outer tub 1 and enhances the integrity of the outer tub 1, facilitating the layout of other structures on the outer tub 1.

[0113] This invention also provides a bucket assembly, including the outer bucket 1 and an inner bucket 3 coaxially disposed within the outer bucket 1.

[0114] This invention also provides a clothing processing device. The aforementioned bucket assembly is installed inside the housing of the clothing processing device, and four hanging parts 11 are provided, corresponding to the four corners of the housing of the clothing processing device.

[0115] In some preferred embodiments, the inner tub 3 of the tub assembly is a large-capacity inner tub 3. Preferably, in this embodiment, the ratio between the axial dimension of the inner tub bottom 31 and the diameter of the inner tub 3 is 0.10 to 0.15. Thus, by reasonably reducing the ratio of the axial dimension of the inner tub bottom 31 to the outer diameter, the inner tub 3 can be expanded without increasing the overall axial dimension of the inner tub 3. At the same time, the center of gravity of the inner tub 3 is lowered, which helps to reduce the vibration amplitude caused by centrifugal force during high-speed spin-drying. Furthermore, the clothes are distributed closer to the inner tub bottom 31, which helps to improve the uniformity of centrifugal force distribution during spin-drying and reduce the risk of eccentricity.

[0116] Preferably, the large capacity specifically means that the capacity of the inner bucket 3 is greater than or equal to 10kg.

[0117] Preferably, in this embodiment, the four hanging parts 11 are arranged at the same height, and the hanging parts 11 are slightly higher than the bottom of the inner barrel 31.

[0118] In some possible embodiments, the dimension of the hanging part 11 in the axial direction of the outer barrel 1 is greater than or equal to 15 mm.

[0119] Example 2

[0120] This embodiment of the invention is used to describe the setting position of the mounting part 11 in the above embodiment one.

[0121] like Figure 3 and Figure 4 As shown, in this embodiment, the hanging part 11 is basically flush with the upper edge of the bottom 31 of the inner tub 3 in the horizontal direction, or the hanging part 11 is higher than the upper edge of the bottom 31 of the inner tub 3.

[0122] In existing technologies, the hanging part 11 is generally positioned close to the bottom of the outer tub 1, flush with the bottom of the outer tub 1, or even below the outer tub 1. With this installation method, the center of gravity of the tub assembly is relatively high, making it prone to significant swaying during operation. Especially for large-capacity garment processing equipment, during washing, rinsing, and spin-drying processes, the tub assembly contains water and clothes, resulting in a significant weight. During operation, the inner tub 3 generates a large rotational force, causing substantial swaying at the upper end of the tub assembly.

[0123] In this embodiment, by reasonably raising the height of the hanging part 11 to be basically flush with the upper edge of the inner tub bottom 31 of the inner tub 3 in the horizontal direction, or by raising the hanging part 11 higher than the upper edge of the inner tub bottom 31 of the inner tub 3, the installation position of the tub assembly can be lowered as a whole without the failure of the shock absorption device. That is, the center of gravity of the tub assembly is lowered relative to the clothing processing equipment. This improves the balancing effect of the shock absorption device on the rotational force of the inner tub 3, which helps to reduce the shaking of the tub assembly. At the same time, the weight of the tub assembly is closer to the bottom of the clothing processing equipment, which improves the compactness of the vertical layout and helps to increase capacity or reduce the overall size of the machine.

[0124] In this embodiment, the top of the hanging part 11 is higher than the upper edge of the inner bucket bottom 31, and the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31 is positively correlated with the capacity of the bucket assembly.

[0125] To prevent the shock absorption device from failing, the hanging part 11 is located near the bottom of the outer tub 1 and is installed on a portion of the side wall of the outer tub 1 that corresponds to the upper edge of the inner tub bottom 31.

[0126] In some possible embodiments, the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31 is proportional to the capacity of the bucket assembly. That is, the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31 is different for bucket assemblies of different capacities; the larger the capacity of the bucket assembly, the greater the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31.

[0127] In some specific embodiments, the capacity of the bucket assembly is 8kg to 12kg, and the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31 varies from -5mm to 45mm.

[0128] In some other possible embodiments, in order to reduce production costs, when the capacity of the bucket assembly is less than or equal to a set value, the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31 is set within a first range, and when the capacity of the bucket assembly is greater than the set value, the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31 is set within a second range.

[0129] In this embodiment, "the height difference between the bottom of the hanging part 11 and the upper edge of the inner tub bottom 31 is within a first range" specifically means that the bottom of the hanging part 11 is basically flush with the upper edge of the inner tub bottom 31. Specifically, the height difference between the bottom of the hanging part 11 and the upper edge of the inner tub bottom 31 is greater than or equal to -5mm and less than or equal to 5mm.

[0130] In some possible embodiments, the difference between the maximum value of the second range and the maximum value of the first range is m, and the difference between the minimum value of the second range and the minimum value of the first range is n, where m is less than or equal to 40 and n is less than or equal to 40. Preferably, m equals n.

[0131] In some specific embodiments, the capacity of the bucket assembly is 8kg to 12kg, and the capacity of the bucket assembly is the same as the capacity of the inner bucket 3. In this embodiment, the axial dimension of the inner bucket 3 is set to 480mm to 560mm.

[0132] In this embodiment, the height difference between the bottom of the hanging part 11 and the upper edge of the inner barrel bottom 31 is set between -5mm and 45mm.

[0133] Specifically, in this embodiment, the capacity of the bucket assembly is set to 10kg. Specifically, the bucket assembly is provided with two suspension schemes. For an inner bucket 3 with a capacity less than or equal to 10kg, the height difference between the bottom of the hanging part 11 and the upper edge of the inner bucket bottom 31 is within a first range, which is -5mm to 5mm.

[0134] For an inner tub 3 with a capacity greater than 10kg, the height difference between the bottom of the hanging part 11 and the upper edge of the bottom 31 of the inner tub is within a second range, which is 35mm to 45mm.

[0135] In this embodiment, by designing the relative position between the hanging part 11 and the bottom of the inner tub 31, the capacity of the tub assembly can be expanded without increasing the overall size of the clothing processing equipment, or with a slight increase in the overall size of the clothing processing equipment. Furthermore, the tub assembly has better stability, avoiding significant shaking of the expanded capacity tub assembly during operation.
