Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of household appliances, and particularly relates to a clothes treatment apparatus. BACKGROUND

[0002] The clothes treatment apparatus is a clothes treatment apparatus which converts electric energy into mechanical energy to wash or dry clothes, and has now entered thousands of households and is very popular.

[0003] At present, the clothes treatment apparatus adopts a motor as a driving component to work, the motor is generally installed on an outer tub of the clothes treatment apparatus, and a damping pad is arranged at a connecting position of the motor and the outer tub; however, the traditional damping pad is easy to cause the relative position of the motor and the outer tub to be unstable, thereby affecting the installation stability of the motor. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the purpose of the present disclosure is to provide a clothes treatment apparatus to solve the technical problem that the relative position of the motor and the outer tub is unstable in the prior art, thereby affecting the installation stability of the motor.

[0005] To achieve at least one of the above purposes, the present disclosure provides the following technical solutions:

[0006] A clothes treatment apparatus is provided, comprising:

[0007] a cabinet, a tub assembly and a motor arranged inside the cabinet;

[0008] The tub assembly comprises:

[0009] an outer tub connected with the cabinet;

[0010] an inner tub rotatably arranged inside the outer tub;

[0011] the motor is arranged at the outer periphery of the outer tub, and the motor is configured to drive the inner tub to rotate;

[0012] The clothes treatment apparatus further comprises:

[0013] a connecting assembly configured to connect the motor and the outer tub;

[0014] The connecting assembly comprises:

[0015] a support arm arranged on the shell of the motor;

[0016] a first connecting portion arranged on the support arm;

[0017] a second connecting portion arranged on the outer tub;

[0018] One of the first connecting portion and the second connecting portion is a column structure, and the other is a cavity structure, and the column structure and the cavity structure are inserted and matched;

[0019] The connecting assembly further comprises:

[0020] The damping pad is provided with a plug-in hole matched with the column structure, so that at least part of the damping pad is clamped between the column structure and the inner wall of the cavity structure;

[0021] The damping pad comprises:

[0022] The body is in a cylindrical shape;

[0023] The reinforcing portion is arranged on the outer periphery of the body;

[0024] In the plug-in direction, the thickness of the reinforcing portion is configured to be larger in the middle and smaller at both ends;

[0025] The plug-in direction is the direction in which the column structure is inserted into the plug-in hole;

[0026] The thickness of the reinforcing portion is the dimension of the reinforcing portion in the radial direction of the body.

[0027] In the above technical solution, the damping pad is clamped between the column structure and the inner wall of the cavity structure, and the force between the column structure and the cavity structure mainly exists in a plane perpendicular to the plug-in direction; that is, the damping pad is subjected to a force in the radial direction when the damping pad as a whole is in a cylindrical or drum-like structure. The thickness of the reinforcing portion is designed to be larger in the middle and smaller at both ends, so that the radial dimension of the middle part of the damping pad in the plug-in direction is larger, the static stiffness of the damping pad is enhanced, especially the static stiffness in the radial direction. Therefore, a larger force needs to be overcome to cause the radial deformation of the damping pad, that is, the damping pad can resist a larger force in the radial direction, can more effectively suppress the radial deformation, and can improve the stability of the motor and the outer cylinder connection.

[0028] In some embodiments, in the plug-in direction, the thickness of the reinforcing portion is configured to decrease from the middle to both ends.

[0029] In the above technical solution, the thickness of the reinforcing portion is gradually changed. On the one hand, when the thickness of the reinforcing portion is changed in steps, stress concentration occurs at the position where the thickness changes, which reduces the static stiffness of the damping pad and maintains the uniformity of the force change of each part of the damping pad. The damping pad has stronger resistance to radial deformation; on the other hand, the thickness of the reinforcing portion gradually changes from the middle to both ends, the cavity structure and the damping pad structure are matched, the damping pad is inserted into the cavity structure more conveniently, and the insertion process is not prone to jamming.

[0030] In some embodiments, the surface of the reinforcing portion away from the body is a curved surface, and the curvature of the curved surface in the plug-in direction is K;

[0031] K satisfies: 0.03 rad / mm < K < 0.12 rad / mm.

[0032] In the technical solution, the outer circumferential surface of the damping pad is a smooth curved surface, and the curvature of the curved surface is in the above range, so that the static stiffness of the damping pad is enhanced, the problem of stress concentration is reduced, and the radial deformation amount is more effectively inhibited.

[0033] In some embodiments, an anti-rotation fit is provided between the column structure and the insertion hole to limit the rotation of the damping pad relative to the column structure around the insertion direction.

[0034] In the technical solution, the anti-rotation fit is provided to limit the rotation of the damping pad, and the damping pad is clamped between the column structure and the cavity structure, so that the damping pad is not easy to deflect and remains stationary with the column structure and the cavity structure, the risk of wear between the damping pad and the inner walls of the column structure and the cavity structure due to deflection of the damping pad is reduced, component damage is reduced, and the stability of the motor connected to the outer cylinder is improved.

[0035] In some embodiments, the insertion hole has a third cross section perpendicular to the insertion direction, the maximum dimension of the third cross section in the first direction is a first dimension, and the maximum dimension of the third cross section in the height direction of the cabinet is a second dimension.

[0036] The first dimension is smaller than the second dimension.

[0037] The first direction is perpendicular to the insertion direction and does not coincide with the height direction of the cabinet.

[0038] In the technical solution, the height direction of the cabinet is generally vertical in the normal working state of the laundry treatment apparatus, and the gravity of the motor acts on the column structure to exert a force on the column structure in the height direction of the cabinet. The third cross section of the insertion hole is designed to have the maximum dimension in the height direction of the cabinet, and the column structure is shaped to fit the insertion hole, i.e., the cross section of the column structure in the specified plane also has the maximum dimension in the height direction of the cabinet. It should be understood that the damping pad is clamped between the column structure and the inner wall of the cavity structure and mainly functions to absorb the vibration of the column structure, so the hardness of the damping pad is generally less than that of the column structure. Therefore, in combination with the design that the cross section of the column structure in the specified plane has the maximum dimension in the height direction of the cabinet, the overall column structure and damping pad can better withstand the load in the height direction of the cabinet, and the firmness of the motor connected to the outer cylinder is improved.

[0039] In some embodiments, the cross section of the insertion hole perpendicular to the insertion direction is elliptical.

[0040] In the technical solution, the cross section of the insertion hole is designed to be elliptical, and the rotation of the damping pad relative to the column structure is limited by the cooperation between the column structure and the side wall of the insertion hole, so that a limiting structure is not needed to limit the rotation of the damping pad, and the operation is more convenient during production or subsequent assembly.

[0041] In some embodiments, the two ends of the insertion hole facing away from each other are a first end and a second end, and the column structure is inserted into the insertion hole from the first end;

[0042] The opening of the insertion hole at the first end is flared.

[0043] In the above technical solution, when the damping pad is sleeved on the column structure, the column structure is inserted into the insertion hole from the flared end of the insertion hole, without the need for special alignment operation of the column structure and the insertion hole, and the alignment and insertion can be conveniently realized.

[0044] In some embodiments, the cylinder assembly further comprises a support structure configured to support the outer cylinder and connect the outer cylinder to the box through the support structure;

[0045] The second connecting part is provided on the outer cylinder through the support structure.

[0046] In the above technical solution, the motor is directly connected to the support structure through the connection assembly. Since the rigidity of the support structure is much greater than that of the outer cylinder with a thin wall structure, connecting the motor to the support structure can improve the installation strength of the motor and ensure the stability of the motor after assembly. Moreover, the motor is connected to the outer cylinder through the support structure, so that the vibration force generated by the motor during operation needs to be transmitted to the outer cylinder through the support structure, prolonging the vibration transmission path, reducing the force transmitted from the motor to the outer cylinder, and thus reducing the vibration of the outer cylinder and improving the damping effect.

[0047] In some embodiments, the number of connection assemblies is at least two, and fasteners are provided on at least part of the connection assemblies.

[0048] The fastener is configured to lock the first connecting part and the second connecting part.

[0049] In the above technical solution, the connection assembly is used to connect the motor and the outer cylinder through insertion, which is convenient to operate. Fasteners are provided on at least part of the connection assemblies to assist in fixing, which can ensure the firmness of the connection between the motor and the outer cylinder.

[0050] In some embodiments, the number of connection assemblies is three, and the three connection assemblies are divided into a middle connection assembly and two side connection assemblies, and the two side connection assemblies are distributed on both sides of the middle connection assembly along the horizontal direction.

[0051] The number of fasteners is one, and the fastener is connected to the middle connection assembly.

[0052] In the technical solution, the two connecting assemblies are directly connected through plug-in connection, and only the fastener is arranged on the middle connecting assembly to fix, so that the installation process is convenient to operate and the motor connected to the outer cylinder has sufficient stability; when the motor vibrates, the motor swings along the horizontal direction with the middle connecting assembly as the midpoint, has good vibration absorption effect, and can effectively isolate the motor vibration.

It should be understood that the thickness, length, and other dimensions of various components in the embodiments of this disclosure shown in the drawings, as well as the overall thickness, length, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this disclosure.

[0081] As part of the inventive concept of this disclosure, before describing the embodiments of this disclosure, it is necessary to analyze the reasons for the problems of low vibration absorption efficiency and poor vibration reduction effect of vibration damping pads in related technologies, and obtain the technical solutions of the embodiments of this disclosure through reasonable analysis.

[0082] In related technologies, clothing processing equipment is a device that converts electrical energy into mechanical energy to wash or dry clothes. It is now widely used in households. Currently, clothing processing equipment uses a motor as the drive component. The motor is generally mounted on the outer drum of the equipment, connected to it via a plug-in structure. Specifically, the plug-in structure includes a connecting post on the motor and a connecting cavity on the outer drum, with the connecting post inserted into the cavity. The equipment also includes vibration damping pads with insertion holes for the connecting post, sandwiched between the connecting post and the inner wall of the connecting cavity. The connecting post is horizontally positioned, and the weight of the motor acts on the damping pad through it, causing radial deformation. This leads to a misalignment of the motor relative to the outer drum, compromising the stability of the motor's relative position and affecting the stability of the motor installation.

[0083] To address this issue, this disclosure provides a garment processing device that solves the technical problem in the prior art where the relative position between the motor and the outer cylinder is not secure, affecting the stability of motor installation, by changing the shape, structure, and installation method of the vibration damping pad.

[0084] The technical solutions of the embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0085] Clothing processing equipment can be a drum washing machine, a washer-dryer combo, etc. For ease of description, the following explanation will use a drum washing machine as an example.

[0086] Please refer to the above. Figures 1 to 5 , Figure 1 A schematic diagram of the overall structure of a garment processing device is provided, showing the basic components of the garment processing device. Figure 2 A schematic diagram of a garment processing device is provided, showing the connection between a motor and an outer cylinder via a support structure; the diagram illustrates the relative positions of the motor and the outer cylinder. Figure 3A schematic view of a connection structure of a motor and an outer cylinder support is provided. Figure 4 A schematic view of a structure of a connection assembly is provided; wherein the main components of the connection assembly are shown. Figure 5 A schematic view of a structure of a damping pad is provided.

[0087] In an embodiment of the present disclosure, a laundry treating apparatus is provided, as shown in the figure. Figures 1 to 3 The laundry treating apparatus includes a cabinet 1, a cylinder assembly 2, and a motor 3. The cylinder assembly 2 is arranged in the interior of the cabinet 1, and the motor 3 is arranged in the interior of the cabinet 1 and located at the outer periphery of the cylinder assembly 2. The motor 3 can drive the cylinder assembly 2 to work to complete washing or drying and the like.

[0088] In the embodiment, the cabinet 1 forms the shell of the laundry treating apparatus, which is generally a rectangular hollow structure. The appearance shape of the cabinet 1 can be designed as required, which is not limited herein. The cabinet 1 is internally provided with a receiving cavity, which can provide installation space for components such as the cylinder assembly 2 and the motor 3.

[0089] The cabinet 1 is provided with a dropping port 11, which can be substantially circular and arranged on the front end face of the cabinet 1. The dropping port 11 communicates with the receiving cavity. Of course, the dropping port can also be arranged on other end faces of the cabinet 1, which is not limited herein. However, for a conventional drum washing machine, the dropping port is generally arranged on the front end face of the cabinet 1.

[0090] The cabinet 1 is further provided with a door body 12, which is movably connected to the cabinet 1 near the dropping port 11 through a hinge shaft to open or close the dropping port 111.

[0091] In the embodiment, the cylinder assembly 2 is arranged in the receiving cavity of the cabinet 1 and can be used for washing, rinsing, dewatering, and drying of laundry.

[0092] The cylinder assembly 2 is provided with a cylinder port, which can be substantially circular and arranged on the front end face of the cylinder assembly 2. The cylinder port is arranged opposite to the dropping port.

[0093] The cylinder assembly 2 further has a washing cavity, which can hold laundry. After the door body is opened, laundry can be put into or taken out of the washing cavity through the dropping port and the cylinder port.

[0094] The cylinder assembly 2 includes an outer cylinder 21 and an inner cylinder 22. The outer cylinder 21 is arranged in the receiving cavity of the cabinet 1, and the inner cylinder 22 is rotatably arranged in the interior of the outer cylinder 21 through a rotating shaft. The washing cavity is formed in the interior of the inner cylinder 22, so that the inner cylinder 22 can drive the laundry to rotate relative to the outer cylinder, thereby improving the uniformity of laundry washing and laundry dewatering. The outer cylinder 21 and the inner cylinder 22 can be coaxially arranged inside and outside. The front end of the outer cylinder 21 and the front end of the inner cylinder 22 are both provided with oppositely arranged openings, and the front end opening of the outer cylinder 21 can serve as the cylinder port of the cylinder assembly 2.

[0095] In the embodiment, the motor 3 is arranged on the outer periphery of the outer cylinder 21 as a driving component for driving the inner cylinder 22.

[0096] As shown in Figure 3 With Figure 4 shown, the laundry treatment apparatus further comprises a connecting assembly 4 configured to connect the cylinder assembly 2 and the motor 3.

[0097] Specifically, the connecting assembly 4 comprises a support arm 41, a first connecting part 42 and a second connecting part 43. The support arm 41 is arranged on the housing of the motor 3, the first connecting part 42 is arranged on the support arm 41, and the second connecting part 43 is arranged on the outer cylinder 21. One of the first connecting part 42 and the second connecting part 43 is a column structure, and the other is a cavity structure, and the column structure and the cavity structure are inserted and matched.

[0098] Specifically, in the first case, the first connecting part 42 is a column structure connected to the support arm 41, and the second connecting part 43 is a cavity structure arranged on the outer cylinder 21, and the first connecting part 42 is inserted into the second connecting part 43. In the second case, the first connecting part 42 is a cavity structure arranged on the support arm 41, and the second connecting part 43 is a column structure connected to the outer cylinder 21, and the second connecting part 43 is inserted into the first connecting part 42. The first case is taken as an example for description in the embodiment.

[0099] Optionally, the support arm 41 and the housing of the motor 3 are integrally formed, and the first connecting part 42 and the support arm 41 are also integrally formed. The integrally formed structure has higher overall rigidity, improves the stability of the motor 3 installation, and reduces the assembly time and assembly error, improves the work efficiency and assembly quality.

[0100] Further, as shown in Figure 4 and Figure 5 , the connecting assembly 4 further comprises a damping pad 44, the damping pad 44 is provided with an insertion hole 441 matched with the column structure, and the damping pad 44 is sleeved on the column structure, so that at least part of the damping pad 44 is clamped between the inner wall of the column structure and the cavity structure.

[0101] For ease of description, in the embodiment, the direction in which the column structure is inserted into the insertion hole 441 is defined as the insertion direction.

[0102] The damping pad 44 can be made of damping material, which can be rubber, EVA (ethylene vinyl acetate copolymer), ACF (artificial cartilage foam), PU (polyurethane), etc.

[0103] The motor 3 is mounted on the outer cylinder 21 in a hanging state, and the insertion direction is along the horizontal direction. Alternatively, the insertion direction can be adjusted according to actual needs, so that the insertion direction has a certain angle with the horizontal direction, for example, the insertion direction is upward and obliquely upward.

[0104] Referring to Figure 5 and Figure 6 , Figure 5 A schematic diagram of the overall structure of the damping pad is provided, showing the main structure of the damping pad. Figure 6 A schematic diagram of the cross-sectional structure of the damping pad is provided, showing the shape of the outer periphery of the damping pad and the shape of the insertion hole.

[0105] As Figure 5 and Figure 6 shown, the damping pad 44 includes a body 442 and a reinforcing portion 443. The body 442 is cylindrical, and the insertion hole 441 is arranged on the body 442. The reinforcing portion 443 is arranged on the outer periphery of the body 442, and the outer periphery of the reinforcing portion 443 is a surface of revolution coaxial with the outer periphery of the body 442. In the insertion direction, the thickness of the reinforcing portion 443 is configured to be large in the middle and small at both ends.

[0106] Specifically, the reinforcing portion 443 has two ends arranged in the insertion direction, referred to as A end and B end. The large in the middle and small at both ends means that the thickness of the reinforcing portion 443 at the middle position between the A end and the B end is greater than the thickness of the two end positions of the A end and the B end.

[0107] The thickness of the reinforcing portion 443 refers to the dimension of the reinforcing portion 443 in the radial direction of the body 442. For ease of description, the radial direction referred to in this embodiment refers to the radial direction of the body 442.

[0108] In this way, the damping pad 44 has a cylindrical structure or a drum-like structure as a whole. The radial dimension of the damping pad 44 is larger in the middle part in the insertion direction, which can enhance the static stiffness of the damping pad 44, especially the static stiffness in the radial direction. This makes the damping pad 44 more effectively suppress the radial deformation, and the position of the motor 3 relative to the outer cylinder 21 is more stable, which improves the stability of the connection between the motor 3 and the outer cylinder 21.

[0109] Optionally, the body 442 and the reinforcing portion 443 are integrally formed. With the integrally formed structure, the structural integrity of the damping pad 44 is maintained, and the structural strength is higher. Compared with the structure formed in parts and then connected, the damping pad 44 is more stable under external load, and the assembly steps can be simplified and the work efficiency is improved.

[0110] Further, in the plug-in direction, the thickness of the reinforcing portion 443 gradually decreases from the middle to the two ends.

[0111] Specifically, the reinforcing portion 443 has two ends arranged in the plug-in direction, referred to as A end and B end. The above-mentioned gradual decrease from the middle to the two ends means that the thickness of the reinforcing portion 443 gradually decreases from the middle part of the A end and the B end to the A end and the B end in two directions.

[0112] The thickness of the reinforcing portion 443 is gradually changed. On the one hand, if the thickness of the reinforcing portion 443 is changed in steps, stress concentration occurs at the position where the thickness of the damping pad 44 changes, which reduces the static stiffness of the damping pad 44. The uniformity of the stress change of each part of the damping pad 44 is maintained, and the damping pad 44 has stronger resistance to radial deformation. On the other hand, the thickness of the reinforcing portion 443 gradually changes from the middle to the two ends. The cavity structure is matched with the structure of the damping pad 44, which makes it more convenient to insert the damping pad 44 into the cavity structure, and the insertion process is not prone to jamming.

[0113] Optionally, the surface of the reinforcing portion 443 away from the body 442 is a curved surface, and the curvature of the curved surface in the plug-in direction is K, and K satisfies: 0.03 rad / mm < K < 0.12 rad / mm.

[0114] The surface of the reinforcing portion 443 away from the body 442 is provided with a curvature in the plug-in direction, so that the outer circumferential surface of the damping pad 44 is a spherical surface. Through the above-mentioned setting, the damping pad 44 is not prone to stress concentration, and the static stiffness of the damping pad 44 is improved. In addition, the curvature of the curved surface is set in the above-mentioned range, which enhances the static stiffness of the damping pad 44 and more effectively suppresses the radial deformation.

[0115] If the curvature of the curved surface is not greater than 0.03, it indicates that the outer circumferential surface of the reinforcing portion 443 is too flat in the plug-in direction. In the plug-in direction, the thickness of the middle part increases less than the thickness of the two end parts, and it is difficult to greatly improve the static stiffness of the damping pad 44.

[0116] If the curvature of the curved surface is not less than 0.12, the outer circumferential surface of the surface reinforcing portion 443 is too bent in the plug-in direction. When the damping pad 44 is subjected to external force, stress concentration is prone to occur, which reduces the static stiffness of the damping pad 44.

[0117] Optionally, the curvature K of the above-mentioned curved surface in the insertion direction is 0.06 rad / mm, and in addition, the value of K can be set to 0.04, 0.05, 0.07, 0.08, 0.09, 0.1, 0.11, etc., and the unit of K is rad / mm.

[0118] Referring to Figures 6 to 8 wherein, Figure 6 A cross-sectional view of the damping pad is provided, showing the outer peripheral surface of the damping pad and the shape of the insertion hole. Figure 7 A cross-sectional view of the damping pad is provided, showing the insertion hole and a schematic view of one of the cross sections of the damping pad perpendicular to the insertion direction. Figure 8 A schematic view of the damping pad along the insertion direction is provided.

[0119] Exemplarily, as Figure 6 shown, the two ends of the insertion hole 441 facing away from each other are respectively a first end 441a and a second end 441b, and the column structure is inserted into the insertion hole 441 from the first end 441a, and the opening of the insertion hole 441 at the first end 441a is flared.

[0120] In this way, when the damping pad 44 is fitted on the column structure, the column structure is inserted from one end of the flared insertion hole 441, without the need for special alignment operation of the column structure and the insertion hole 441, and the alignment and insertion can be conveniently achieved, and the operation is convenient.

[0121] Further, the extension trend of the flared portion extends from the first end 441a to the second end 441b, i.e., the cross-sectional dimension of the insertion hole 441 perpendicular to the insertion direction decreases along the insertion direction, i.e., the insertion hole 441 and the column structure are a matching table structure.

[0122] Through the above-mentioned arrangement, while improving the convenience of inserting the column structure into the insertion hole 441, the stability of the connection between the damping pad 44 and the column structure is also improved.

[0123] Specifically, when the damping pad 44 is subjected to a force in the opposite direction of the insertion direction, the column structure surface and the inner wall of the insertion hole 441 remain in a tightly abutting state, which can ensure the stability of the relative position of the damping pad 44 and the column structure. If the cross-sectional dimension of the insertion hole 441 is the same in the insertion direction, a gap will exist between the column structure and the inner wall of the insertion hole 441 due to processing errors, which will cause the damping pad 44 to easily shake relative to the column structure, thereby affecting the stability of the connection between the motor 3 and the outer cylinder 21.

[0124] In addition, the column structure connected to one end of the support arm 41 has a larger cross-sectional size, which is beneficial to improve the firmness of the column structure connected to the support arm 41, that is, the motor 3 is more stable and firm in connection with the outer cylinder.

[0125] In some embodiments, with reference to Figure 7 and Figure 8 , the column structure and the insertion hole 441 are provided with anti-rotation matching to limit the rotation of the damping pad 44 relative to the column structure around the insertion direction. Wherein, the anti-rotation matching can be achieved by setting the cross-sectional shape of the column structure and the insertion hole 441 to limit the rotation of the damping pad 44, or a limiting structure can be provided between the column structure and the insertion hole 441 to limit the rotation of the damping pad 44.

[0126] By setting the anti-rotation matching to limit the rotation of the damping pad 44, the damping pad 44 is clamped between the column structure and the cavity structure, and is not easy to deflect, reducing the problem of wear between the damping pad 44 and the inner wall of the column structure and the cavity structure due to the rotation of the damping pad 44, reducing the problem of deformation of the components due to wear over time, improving the stability of the connection between the motor 3 and the outer cylinder 21, and reducing the problem of unstable connection between the motor 3 and the outer cylinder 21 due to wear of the damping pad 44.

[0127] Optionally, as shown in Figure 7 and 8 , the cross section of the insertion hole 441 perpendicular to the insertion direction is elliptical, and correspondingly, the cross section of the column structure perpendicular to the insertion direction is also elliptical, and the column structure and the insertion hole 441 are matched. By matching the cross-sectional shape of the insertion hole 441 and the column structure, the function of limiting the rotation of the damping pad 44 relative to the column structure and the cavity structure can be achieved.

[0128] In addition, the shape of the cross section of the insertion hole 441 perpendicular to the insertion direction can also be set to a non-circular shape such as a triangle, a quadrilateral, a pentagon, etc., and the column structure and the insertion hole 441 are matched, which can achieve the function of limiting the deflection of the damping pad 44 relative to the column structure.

[0129] Optionally, a limiting structure can also be provided between the column structure and the insertion hole 441 to limit the rotation of the damping pad 44. For example, a limiting protrusion extending in the insertion direction is provided on the outer circumferential surface of the column structure, and a limiting groove matched with the limiting protrusion is formed on the inner wall of the insertion hole 441, the limiting protrusion is embedded in the limiting groove, and the rotation of the damping pad 44 relative to the column structure is limited.

[0130] As shown in Figure 7 , the insertion hole 441 has a third cross section perpendicular to the insertion direction, the maximum size of the third cross section in the first direction is a first size, and the maximum size of the third cross section in the height direction of the cabinet 1 is a second size, and the first size is smaller than the second size. Wherein, the first direction is perpendicular to the insertion direction and does not coincide with the height direction of the cabinet 1.

[0131] In the normal working state of the laundry treatment apparatus, the height direction of the cabinet 1 is generally a vertical direction, and the gravity of the motor 3 acts on the column structure to exert a force on the column structure in the height direction of the cabinet 1. The third cross section in which the insertion hole 441 is arranged has the largest dimension in the height direction of the cabinet 1, and the column structure is shaped to fit the insertion hole 441, that is, the cross section of the column structure in the set plane also has the largest dimension in the height direction of the cabinet 1.

[0132] At the same time, it should be understood that the damping pad 44 is clamped between the column structure and the inner wall of the cavity structure, and mainly plays a role in absorbing the vibration of the column structure, so the hardness of the damping pad 44 is generally less than the hardness of the column structure. Therefore, in combination with the design that the cross section of the column structure in the set plane has the largest dimension in the height direction of the cabinet 1, the overall column structure and damping pad 44 can bear a load more strongly in the height direction of the cabinet 1, and the firmness of the motor 3 connected to the outer cylinder 21 can be improved.

[0133] Exemplarily, in the case where the cross section of the insertion hole 441 is in an oval shape, the long diameter of the oval shape is arranged along the height direction of the cabinet 1.

[0134] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 2 A structural diagram of the connection between the motor and the cylinder assembly is provided. Figure 3 and Figure 4 A schematic diagram of the connection between the motor and the support structure through the connection assembly is provided, which shows the specific structure of the connection assembly and the connection relationship with the motor and the outer cylinder support. Figure 9 A structural diagram of the connection between the fastener and the first connection part and the second connection part is provided, which shows the specific structure of the fastener and the cooperation relationship with the connection assembly. Figure 10 A structural diagram of the assembly of the fastener is provided, which shows that three connection assemblies are arranged, and the fastener is connected to the middle connection assembly.

[0135] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , the cylinder assembly 2 further includes a support structure 23 configured to support the outer cylinder 21 and connect the outer cylinder 21 to the cabinet 1 through the support structure 23. The second connection part 43 is arranged on the outer cylinder 21 through the support structure 23. Taking the second connection part 43 as an example, the second connection part 43 is arranged on the support structure 23.

[0136] By setting the support structure 23, the second connecting structure 43 is set on the support structure 23 instead of being directly set on the outer cylinder 21; the structural strength of the support structure 23 is much greater than that of the outer cylinder 21 in a thin-walled structure, so that the stability of the motor 3 installation can be improved. And by setting the support structure 23, the transmission path of the vibration generated by the motor 3 to the outer cylinder 21 and the cabinet 1 can be extended, the amount of vibration transmitted to the outside can be reduced, and the vibration reduction effect can be improved.

[0137] As shown in Figure 9 The clothes treatment apparatus also includes a fastener 5 configured to be connected to the connecting assembly 4 to lock the first connecting part 42 and the second connecting part 43; in this embodiment, the number of connecting assemblies 4 is at least two, and at least part of the connecting assemblies 4 are provided with the fastener 5 to ensure the firmness of the connection between the motor 3 and the outer cylinder 21.

[0138] Specifically, the fastener 5 includes a fastening bolt 51 and a gasket 52, wherein the gasket 52 is a metal gasket or made of other hard materials. The gasket 52 is attached to the side of the support structure 23 away from the support arm 41, and the fastening bolt 51 penetrates the gasket 52 and is threadedly connected with the column structure; by tightening the fastening bolt 51, a pressure is applied to the support structure 23 in the direction of the support arm 41, the support structure 23 is relatively locked with the support arm 41, and the locking of the first connecting part 42 and the second connecting part 43 is realized.

[0139] In addition, the fastener 5 can also include a rubber pad arranged between the gasket 52 and the support structure 23. When the support structure 23 and the support arm 41 are locked by the fastening bolt 51, the stability of the abutment between the gasket 52 and the support structure 23 is ensured, the stress is more uniform, the problem of deformation of the gasket 52 affecting the stability of the connection between the support structure 23 and the support arm 41 can be reduced, and the firmness of the connection between the motor 3 and the outer cylinder 21 can be improved.

[0140] Alternatively, the connecting assembly 4 is provided with two, and correspondingly, the two column structures are arranged in a horizontal direction; the fastener 5 can be provided with one or two. In this embodiment, the fastener 5 is also provided with two, and the two fasteners 5 are connected to the two column structures, respectively.

[0141] In this way, the motor 3 is connected to the outer cylinder 21, the uniformity of the constraint force applied to the motor 3 can be ensured, the problem of stress concentration at the connection position caused by uneven stress can be avoided, and the stability of the connection between the motor 3 and the outer cylinder 21 can be improved.

[0142] Alternatively, as shown in Figure 10As shown, the number of connecting assemblies 4 is three, one of which is a middle connecting assembly 4 and the other two are side connecting assemblies 4, which are distributed on both sides of the middle connecting assembly 4 along the horizontal direction. The number of fasteners 5 is one, which is connected to the middle connecting assembly 4.

[0143] The middle connecting assembly 4 is locked by insertion and bolting, and the side connecting assembly 4 is locked by insertion. When the motor 3 vibrates, it will swing along the horizontal direction with the middle connecting assembly 4 as the midpoint, improving the effect of vibration absorption and energy absorption, and more effectively isolating the vibration of the motor 3.

[0144] In addition, the two side connecting assemblies 4 are directly connected by insertion, and only the middle connecting assembly 4 is fixed by the fastener 5, so the installation process is more convenient.

[0145] Optionally, when the number of connecting assemblies 4 is three, the number of fasteners 5 is two. The two fasteners 5 are arranged on the two side connecting assemblies 4, which can ensure the uniformity of force on the connecting part of the multiple connecting assemblies 4, avoid stress concentration caused by uneven force, and improve the stability of the connection.

[0146] Optionally, when the number of connecting assemblies 4 is three, the number of fasteners 5 is three. The three fasteners 5 are arranged on the three connecting assemblies 4, which can ensure the firmness of the motor 3 installation.

[0147] It should be noted that the two side connecting assemblies 4 in the embodiment are distributed on both sides of the middle connecting assembly 4 along the horizontal direction, which means that the arrangement direction of any side connecting assembly 4 and the middle connecting assembly 4 has at least a component in the horizontal direction.

[0148] For example, a spatial rectangular coordinate system is constructed, in which the X-axis is along the horizontal direction, so that the arrangement direction of any side connecting assembly 4 and the middle connecting assembly 4 has at least a component in the X-axis; and the components in the Y-axis and the Z-axis can be determined as needed.

[0149] In addition, as shown in the figure, Figure 8 The outer circumferential surface of the damping pad 44 is provided with a protrusion 444, which is located at one end of the damping pad 44 close to the support arm 41.

[0150] When the fastener 5 is used for locking, the support structure 23 is extruded in the direction of the support arm 41, and the support structure 23 and the support arm 41 are clamped together to clamp the protrusion 444. By setting the protrusion 444, the support structure 23 and the support arm 41 can be buffered and damped in the insertion direction.

[0151] In addition, through the convex edge 444 provided, the support structure 23 compresses the convex edge 444 to the support arm 41, the convex edge 444 provides stable support for the support structure 23 and the support arm 41, and ensures the stability of the position of the support structure 23 relative to the support arm 41. Compared with the direct abutment of the support structure 23 and the support arm 41, through the convex edge 444 provided, the support structure 23 and the support arm 41 have a certain assembly allowance, which can ensure that the cylindrical structure and the cavity structure inner wall clamp the damping pad 44, the relative position of the motor 3 and the outer cylinder 21 is more stable, and the stability of the connection between the motor 3 and the outer cylinder 21 is improved.
