[0003] Clothing handling equipment, such as laundry equipment, uses a drum assembly for washing clothes. During the washing process, the vibration generated by the drum assembly is transmitted to the cabinet of the clothing handling equipment, which can easily cause noise from the cabinet, resulting in noise pollution to the surrounding environment and seriously affecting the user's comfort. Utility Model Content

[0004] In view of this, this application aims to provide a vibration damping device and clothing treatment equipment that can improve the vibration reduction and noise reduction effect.

[0005] To achieve the above objectives, this application provides a vibration damping device for clothing processing equipment, comprising:

[0006] First vibration isolation component;

[0007] The second vibration isolator is provided, wherein the first vibration isolator and the second vibration isolator have at least one different vibration isolation parameter, the vibration isolation parameter including hardness, damping characteristics and / or thickness;

[0008] The shock absorber has a first connecting part;

[0009] An adapter is connected to the vibration damper. The adapter has a second connecting portion, and the second connecting portion is provided with a second vibration isolation component. The connection between the vibration damper and the adapter is provided with a first vibration isolation component.

[0010] In some embodiments, the thickness of the second vibration isolator is greater than the thickness of the first vibration isolator;

[0011] And / or, the hardness of the second vibration isolator is less than the hardness of the first vibration isolator.

[0012] In some embodiments, the second vibration isolation member is a damped vibration isolation member, and the first vibration isolation member is an undamped vibration isolation member.

[0013] In some embodiments, the vibration damper includes:

[0014] A sleeve having the first connecting portion;

[0015] A friction rod, wherein a first end of the friction rod along its axial direction is slidably inserted into the sleeve, and a second end of the friction rod along its axial direction is connected to the adapter, and the first vibration isolator is provided at the connection between the second end of the friction rod and the adapter.

[0016] In some embodiments, the vibration damping device includes a third vibration isolator, the first connection portion having a first hinge hole extending along a first direction, at least a portion of the third vibration isolator being disposed within the first hinge hole, wherein the first direction is perpendicular to the axial direction of the friction rod.

[0017] In some embodiments, the second connection portion has a second hinge hole extending along a first direction, and at least a portion of the second vibration isolator is disposed within the second hinge hole.

[0018] In some embodiments, the damper includes a friction damping element disposed between the friction rod and the sleeve, wherein the friction damping element and the friction rod slide relative to each other.

[0019] In some embodiments, the vibration damper has a connecting hole extending in a first direction, the adapter has a positioning portion, the first vibration isolator has a positioning hole extending in the first direction, at least a portion of the first vibration isolator is disposed in the connecting hole, and the positioning portion passes through the positioning hole.

[0020] In some embodiments, the adapter has two limiting portions, which are spaced apart along a second direction, and the portion of the damper with the connecting hole is located between the two limiting portions, wherein the first direction and the second direction are perpendicular to each other.

[0021] This application also provides a garment processing device, comprising:

[0022] Barrel body components;

[0023] Box;

[0024] In any of the above-mentioned vibration damping devices, one of the first connecting portion and the second connecting portion is connected to the barrel assembly, and the other of the first connecting portion and the second connecting portion is connected to the box body.

[0025] The vibration damping device provided in this application embodiment achieves frictional damping vibration reduction by generating damping force through a vibration damper. The frictional damping force generated by the vibration damper is transmitted to a first vibration isolator, then to a transition member, and finally to a second vibration isolator, and finally to another component in the barrel assembly and the box assembly, thus achieving a secondary vibration isolation effect. The rate of attenuation of vibration energy in structures with different thicknesses, hardnesses, and / or damping characteristics is greater than that in structures with uniform thicknesses, hardnesses, and damping characteristics. Therefore, the third vibration isolator and the second vibration isolator have at least one different vibration isolation parameter, which can achieve attenuation of vibration transmission. During operation, clothing and / or water entering the tank assembly of the garment processing equipment causes changes in its weight. This results in multi-directional vibrations within the tank assembly, and these weight and positional changes can alter the vibration frequency. Furthermore, different vibration isolation parameters in the first and second vibration isolation components can absorb more vibration energy, increasing energy loss along the transmission path. Therefore, designing different isolation parameters for the first and second vibration isolation components allows them to absorb vibrations of different frequencies, effectively reducing vibration over a wide frequency range to accommodate the vibrations generated by the tank assembly and housing. In this way, the frictional damping force generated by the damper is absorbed and buffered multiple times by the first and second vibration isolation components, significantly attenuating the impact energy. This effectively reduces the overall vibration of the garment processing equipment, ultimately lowering noise levels, reducing environmental noise pollution, and improving user comfort.

The detailed description in the specific implementation should be understood as an explanation of the purpose of this application and should not be regarded as an undue limitation on this application.

It should be understood that these orientational terms are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Please see Figures 2 to 5 This application provides a vibration damping device 100 for use in clothing processing equipment. The vibration damping device 100 includes a first vibration isolation member 110, a second vibration isolation member 120, a vibration damper 130, and an adapter 140.

[0036] The first vibration isolator 110 and the second vibration isolator 120 differ in at least one vibration isolation parameter, which includes hardness, damping characteristics, and / or thickness. The damper 130 has a first connecting portion 131, and a connector 140 is connected to the damper 130. The connector 140 also has a second connecting portion 141, where the second vibration isolator 120 is disposed. The first vibration isolator 110 is disposed at the connection between the damper 130 and the connector 140.

[0037] The vibration damping device 100 can connect to two components of the garment processing equipment that require vibration damping. The first connecting part 131 and the second connecting part 141 are respectively used to connect to the two components of the garment processing equipment.

[0038] Vibration damper 110 can generate damping force for damping and vibration reduction. For example, vibration damper 130 can generate frictional damping force for vibration reduction. Both the second vibration isolator 120 and the first vibration isolator 110 are on the damping force transmission path of vibration damper 130. Both the second vibration isolator 120 and the first vibration isolator 110 can dissipate vibration energy through their own deformation, thus playing a buffering and vibration reduction role.

[0039] Please see Figure 1 This application provides a garment processing device, which includes a drum assembly 200, a housing, and a vibration damping device 100 as described in any embodiment of this application. The drum assembly 200 is located inside the housing.

[0040] One of the first connecting portion 131 and the second connecting portion 141 is connected to the barrel assembly 200, and the other of the first connecting portion 131 and the second connecting portion 141 is connected to the box body. Exemplarily, in some embodiments, if the first connecting portion 131 is connected to the barrel assembly 200, then the second connecting portion 141 is connected to the box body. In other embodiments, if the second connecting portion 141 is connected to the barrel assembly 200, then the first connecting portion 131 is connected to the box body.

[0041] The clothing processing equipment provided in this application can have washing and / or drying functions, that is, the clothing processing equipment can be used to wash and / or dry clothes.

[0042] The container assembly 200 is used for placing and processing clothing. Exemplarily, in one embodiment, the container assembly 200 includes a clothes-holding tube and an outer tube, the clothes-holding tube being rotatably disposed within the outer tube, the clothes-holding tube having a clothing processing chamber. The outer tube can remain stationary. Clothing is placed within the clothing processing chamber.

[0043] During operation, such as when the garment processing equipment (e.g., the drum assembly 200) processes garments, the rotating drum causes the outer drum to vibrate. The magnitude of this vibration is primarily determined by the total system mass, the system's balance, and the damping force of the vibration damper 130. To achieve optimal vibration reduction while keeping the total system mass and balance constant, increasing the damping force of the vibration damper 130 is often used. However, increasing the damping force of the vibration damper 130 increases the impact force it exerts on the internal system and the housing, ultimately leading to increased noise.

[0044] The vibration damping device 100 provided in this embodiment achieves frictional damping vibration reduction by generating damping force through the vibration damper 130. The damping force generated by the vibration damper 130 is transmitted to the adapter 140 through the first vibration isolation member 110, and then to the second vibration isolation member 120 through the adapter 140, and finally to the barrel assembly 200 and another box in the box, thus achieving a secondary vibration isolation effect. The rate of attenuation of vibration energy in structures with different thicknesses, hardnesses and / or damping characteristics is greater than that in structures with uniform thicknesses, hardnesses and damping characteristics. Therefore, the third vibration isolation member 150 and the second vibration isolation member 120 have at least one different vibration isolation parameter, which can achieve attenuation of vibration transmission. During use, clothing and / or water enter the tank assembly 200, causing changes in its weight. This results in the tank assembly 200 vibrating in multiple directions during operation. Changes in both weight and position of the tank assembly 200 can alter the vibration frequency. Furthermore, in the vibration energy transmission path, the first vibration isolator 110 and the second vibration isolator 120, with different isolation parameters, can absorb more vibration energy, increasing energy loss in the transmission path. Therefore, by designing different isolation parameters for the first vibration isolator 110 and the second vibration isolator 120, they can absorb vibrations of different frequencies, effectively reducing vibration over a wider frequency range to adapt to the vibrations generated by the tank assembly 200 and the housing. In this way, the damping force generated by the damper 130 is absorbed and buffered multiple times by the second vibration isolation component 120 and the first vibration isolation component 110. The impact energy from the damping force will be greatly attenuated, thereby effectively reducing the vibration of the whole machine when the clothing processing equipment is working, ultimately reducing the noise of the whole machine, reducing noise pollution to the surrounding environment, and improving the user's comfort.

[0045] In some embodiments, the second connection 141 is connected to the component with the greater vibration response of the two components. For example, see [link to example]. Figure 1 If the damping force generated by the vibration damper 130 has a greater impact on the housing, resulting in more noticeable noise from the housing, then the first connecting part 131 is connected to the housing assembly 200, and the second connecting part 141 is connected to the housing. In this way, the damping force generated by the vibration damper 130 is transmitted to the housing after two stages of damping by the second vibration isolator 120 and the first vibration isolator 110, which can reduce the impact of the damping force generated by the vibration damper 130 on the housing and significantly improve the overall noise level. Conversely, if the damping force generated by the vibration damper 130 has a greater impact on the housing assembly 200, then the first connecting part 131 is connected to the housing, and the second connecting part 141 is connected to the housing assembly 200.

[0046] In one embodiment, the thickness of the second vibration isolator 120 is greater than the thickness of the first vibration isolator 110. Thus, the second vibration isolator 120 has a stronger vibration absorption capacity than the first vibration isolator 110, further reducing the damping force transmitted to the component connected to the second connection portion 141.

[0047] In one embodiment, the hardness of the second vibration isolator 120 is less than that of the first vibration isolator 110. The first vibration isolator 110 and the second vibration isolator 120 are connected in series in the vibration transmission path. The second vibration isolator 120 is in contact with the box or barrel assembly 200. The damping force is transmitted to the box or barrel assembly 200 after being isolated by the first vibration isolator 110 and the second vibration isolator 120 in sequence. The second vibration isolator 120 has a relatively lower hardness and a lower vibration transmission rate than the first vibration isolator 110. In this way, the situation where the compression of one of the first vibration isolator 110 and the second vibration isolator 120 is avoided, which not only reduces the overall vibration transmission rate of the vibration damping device 100 and improves the vibration isolation effect, but also improves the durability of the first vibration isolator 110 and the second vibration isolator 120.

[0048] In one embodiment, the second vibration isolator 120 is a damped vibration isolator, and the first vibration isolator 110 is an undamped vibration isolator. A damped vibration isolator can absorb more vibration energy than an undamped vibration isolator. Since the second connecting portion 141 is used to connect to the component with the greater vibration response of the two components, the second vibration isolator 120 is a damped vibration isolator, which can further absorb more vibration energy and reduce noise.

[0049] In one embodiment, please refer to Figures 2 to 4 The vibration damper 130 includes a sleeve 132 and a friction rod 133. The sleeve 132 has a first connecting portion 131. The first end of the friction rod 133 along its axial direction is slidably inserted into the sleeve 132. The second end of the friction rod 133 along its axial direction is connected to the adapter 140. A first vibration isolation member 110 is provided at the connection between the second end of the friction rod 133 and the adapter 140.

[0050] The first end of the friction rod 133 is inserted into the sleeve 132 and can slide along the axial direction of the friction rod 133 within the sleeve 132. That is, the friction rod 133 can make linear reciprocating motion along the axial direction of the friction rod 133 within the sleeve 132. In this way, the vibration energy from the component is converted into internal energy through the frictional damping between the friction rod 133 and the sleeve 132, thereby achieving the purpose of vibration reduction.

[0051] Both the second vibration isolator 120 and the first vibration isolator 110 are on the transmission path of the friction damping force between the friction rod 133 and the sleeve 132. That is to say, the friction damping force between the friction rod 133 and the sleeve 132 will be transmitted after being damped by the second vibration isolator 120 and the first vibration isolator 110.

[0052] In this embodiment, the vibration generated by the barrel assembly 200 during operation causes the sleeve 132 and the friction rod 133 to slide relative to each other. The relative sliding of the sleeve 132 and the friction rod 133 generates frictional damping force, thereby achieving damping and vibration reduction. The damping force generated by the sliding of the friction rod 133 relative to the sleeve 132 is transmitted to the adapter 140 through the first vibration isolator 110, and then to the second vibration isolator 120 through the adapter 140, and finally to one of the barrel assembly 200 and the box body, thus achieving a secondary vibration isolation effect.

[0053] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The vibration damping device 100 includes a third vibration isolator 150. A first connecting portion 131 has a first hinge hole 131a extending along a first direction. At least a portion of the third vibration isolator 150 is disposed within the first hinge hole 131a, wherein the first direction is perpendicular to the axial direction of the friction rod 133. The third vibration isolator 150 is disposed in the first connecting portion 131. The damping force generated by the sliding of the friction rod 133 relative to the sleeve 132 is buffered and transmitted to the barrel assembly 200 and another component in the box after being isolated by the third vibration isolator 150. The first hinge hole 131a is used for rotatable connection with components such as the barrel assembly 200 or the box. As clothing and / or water enter the tub assembly 200, the weight of the tub assembly 200 changes, and the position of the tub assembly 200 in the vertical direction changes. Therefore, the vibration damping device 100 is rotatably connected to the component through the first hinge hole 131a, so that the vibration damping device 100 and the component, such as the tub assembly 200 or the box, can rotate relative to each other, thereby ensuring a certain degree of freedom, avoiding the vibration damping device 100 from bearing the bending moment from the tub assembly 200, and can further absorb vibration energy through rotation.

[0054] As an example, in one embodiment, please refer to Figures 1 to 2 The third vibration isolator 150 has a first pin hole 150a extending in the first direction. Both the barrel assembly 200 and the box are equipped with mounting bases 300. The mounting bases 300 have mounting holes extending in the first direction. The first connecting part 131 is located in the mounting hole of one of the barrel assembly 200 and the box. The connecting pin 400 passes through the mounting hole and the first pin hole 150a.

[0055] In some embodiments, the first hinge hole 131a penetrates the first end of the sleeve 132 at both ends along the first direction. The third vibration isolator 150 includes a mounting post and two annular protrusions, both of which surround the outer periphery of the mounting post and are spaced apart along the first direction. The first pin hole 150a penetrates the two ends of the mounting post along the first direction. The mounting post passes through the first hinge hole 131a, and the two annular protrusions are located at the two ends of the first hinge hole 131a along the first direction. For example, the mounting post is generally cylindrical. Thus, the two annular protrusions prevent the third vibration isolator 150 from dislodging from the first hinge hole 131a.

[0056] In one embodiment, please refer to Figures 1 to 5 The second connecting portion 141 has a second hinge hole 141a extending along a first direction, and at least a portion of the second vibration damper 120 is disposed within the second hinge hole 141a. The second hinge hole 141a is used for rotatable connection with a component, such as the tub assembly 200 or the box. Because clothing and / or water entering the tub assembly 200 causes a change in the weight of the tub assembly 200, the position of the tub assembly 200 in the vertical direction changes. Therefore, the vibration damping device 100 is rotatably connected to the component through the second hinge hole 141a, allowing the vibration damping device 100 and the component, such as the tub assembly 200 or the box, to rotate relative to each other, thereby ensuring a certain degree of freedom, preventing the vibration damping device 100 from bearing bending moments from the tub assembly 200, and further absorbing vibration energy through rotation.

[0057] As an example, in one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The second vibration isolator 120 has a second pin hole 120a extending in the first direction, and the second connecting part 141 is located in the mounting hole of the other of the barrel assembly 200 and the box body. The connecting pin 400 passes through the mounting hole and the second pin hole 120a.

[0058] In some embodiments, the second hinge hole 141a penetrates both ends of the adapter 140 along the first direction. The second vibration isolator 120 includes a cylindrical portion and two annular protrusions, both of which surround the outer periphery of the cylindrical portion and are spaced apart along the first direction. The second pin hole 120a penetrates both ends of the cylindrical portion along the first direction. The cylindrical portion passes through the second hinge hole 141a, and the two annular protrusions are located at both ends of the second hinge hole 141a along the first direction. For example, the cylindrical portion is generally cylindrical. Thus, the two annular protrusions prevent the second vibration isolator 120 from dislodging from the second hinge hole 141a.

[0059] The connecting pin 400 can be a self-locking pin. For example, the connecting pin 400 can self-lock after passing through the mounting hole and the first pin hole 150a to prevent the connecting pin 400 from falling off.

[0060] In one embodiment, the connecting pin 400 includes a pin rod and a resilient boss. One end of the pin rod forms a screw head, and the diameter of the other end of the pin rod gradually decreases away from the screw head to form a tapered head. A groove is formed on the circumferential surface of the pin rod, and the resilient boss is disposed in the groove and can protrude or retract from the groove. The connecting pin 400 achieves self-locking through the resilient boss. For example, taking the connecting pin 400 installed into the first pin hole 150a as an example, during the process of the tapered head passing through the mounting hole and the first pin hole 150a, the hole wall surface of the mounting hole and the hole wall surface of the first pin hole 150a force the resilient boss to retract from the groove, so that the resilient boss moves to the side of the first connecting part 131 away from the screw head. The force applied to the hole wall surface of the mounting hole and the hole wall surface of the first pin hole 150a is removed, the resilient boss protrudes from the groove, and the mounting seat 300 and the first connecting part 131 are clamped between the screw head and the resilient boss.

[0061] In one embodiment, please refer to Figure 4 The vibration damper 130 includes a friction damping element 134, which is disposed between the friction rod 133 and the sleeve 132. The friction damping element 134 and the friction rod 133 slide relative to each other. That is, the friction damping element 134 and the sleeve 132 remain relatively stationary, and the friction between the friction rod 133 and the friction damping element 134 generates a damping force. The friction damping element 134 can increase the damping coefficient of the sleeve 132, thereby increasing the damping force between the friction rod 133 and the sleeve 132.

[0062] In one embodiment, a friction damping element 134 is disposed within a sleeve 132. The friction damping element 134 has through holes extending through its two end faces along a first direction, and a friction rod 133 is slidably inserted into the through holes. The friction damping element 134 has a generally annular structure, which is simple in structure and easy to manufacture.

[0063] In some exemplary embodiments, the friction damper 134 is generally annular, and the friction rod 133 is a circular rod.

[0064] In one embodiment, please refer to Figures 4 to 5The vibration damper 130 has a connecting hole 130a extending in a first direction, the adapter 140 has a positioning part 142, and the first vibration isolator 110 has a positioning hole 110a extending in the first direction. At least a portion of the first vibration isolator 110 is disposed within the connecting hole 130a, and the positioning part 142 passes through the positioning hole 110a. By using the connection method of the positioning part 142 and the positioning hole 110a, the connection between the vibration damper 130 and the adapter 140 is simple, facilitating the assembly of the vibration damper 130, the first vibration isolator 110, and the adapter 140, and also facilitating the transmission of force between the vibration damper 130 and the adapter 140. The first vibration isolator 110 is disposed between the positioning part 142 and the hole wall of the connecting hole 130a, and the damping force is absorbed by the first vibration isolator 110 and then transmitted to the positioning part 142.

[0065] In some embodiments, the connecting hole 130a penetrates both ends of the second end of the friction rod 133 along the first direction. The first vibration isolator 110 includes a column and two annular flanges, both of which surround the outer periphery of the column and are spaced apart along the first direction. The positioning hole 110a penetrates both ends of the column along the first direction, and the column passes through the connecting hole 130a. The two annular flanges are located at the two ends of the connecting hole 130a along the first direction. For example, the column is generally cylindrical. In this way, the two annular flanges can prevent the first vibration isolator 110 from coming out of the connecting hole 130a.

[0066] In some embodiments, the positioning part 142 is interference-fitted with the positioning hole 110a. This reduces the movement of the positioning part 142 within the positioning hole 110a to a certain extent.

[0067] In one embodiment, please refer to Figures 2 to 5 The adapter 140 has two limiting portions 143, which are spaced apart along a second direction. The portion of the damper 130 with the connecting hole 130a is located between the two limiting portions 143, wherein the first direction and the second direction are perpendicular to each other. The two limiting portions 143 can limit the rotation angle of the damper 130 around the positioning portion 142, thus preventing the connection between the damper 130 and the adapter 140 from impacting the housing. In this way, by limiting the rotation of the damper 130 relative to the adapter 140 through the two limiting portions 143 on the adapter 140, it is not necessary to constrain the adapter 140 and the damper 130 through other components.

[0068] It should be noted that the first direction, the second direction, and the axis of friction rod 133 are perpendicular to each other.

[0069] In one embodiment, at least one vibration isolation parameter is the same for both the third vibration isolator 150 and the first vibration isolator 110, including stiffness, damping characteristics, and thickness. This facilitates the even transmission of the damping force generated by the damper 130, such as the sleeve 132 and the friction rod 133, to the third vibration isolator 150 and the first vibration isolator 110.

[0070] In one exemplary embodiment, the third vibration isolator 150 and the first vibration isolator 110 have the same structure and vibration isolation parameters. The first vibration isolator 110 has a thickness of 3 mm and a stiffness of 70 A, and is an undamped vibration isolator. The second vibration isolator 120 has a thickness of 5 mm and a stiffness of 55 A, and is a damped vibration isolator. With this design, the noise reduction effect can reach more than 1.2 dB on different platforms.

[0071] In one embodiment, please refer to Figures 4 to 5 The adapter 140 includes two bases 1400. Each base 1400 has a positioning part 142, a limiting part 143, a fixing buckle 144, and a second connecting part 141. The positioning parts 142 of the two bases 1400 pass through positioning holes 110a from both sides in a first direction, and the fixing buckles 144 of the two bases 1400 are fixedly connected. On the one hand, the two bases 1400 have the same structural shape, making it easy to manufacture as standard parts and reducing costs. On the other hand, the positioning parts 142 of the two bases 1400 are inserted into the positioning holes 110a from both sides in the first direction, and the fixing buckles 144 of the two bases 1400 are fixedly connected. In this way, both the two bases 1400 can be fixed, and the adapter 140 and the shock absorber 130, such as the friction rod 133, can be assembled. The assembly method is simple and easy to operate.

[0072] For example, garment handling equipment includes, but is not limited to, dryers, laundry equipment, or washer-dryers. A dryer is a garment handling device with a drying function. A laundry equipment is a garment handling device with a washing function. A washer-dryer is a garment handling device with both drying and washing functions.

[0073] In one embodiment, the box can have a hexahedral structure, such as a cube or cuboid. The clothes container is located inside the box, and the box is the exterior component of the clothing processing equipment.

[0074] In one embodiment, a clothing inlet is formed on the front side of the housing, which communicates with the clothing processing chamber of the tub assembly 200. The clothing processing chamber is used to place and process clothing. Methods of processing clothing include, but are not limited to, washing and / or drying. The clothing inlet is used to retrieve and place clothing. For example, a user can place clothing into or retrieve clothing from the clothing processing chamber from the front through the clothing inlet.

[0075] It should be noted that "down" refers to the direction towards the ground, and "up" is the opposite direction of "down". "Front" refers to the direction towards the user, and "back" is the opposite direction of "front". "Left" refers to the side where the user's left hand is when the user is in front of the box, and "right" is the opposite direction of "left". The front-back, left-right, and up-down directions are perpendicular to each other.

[0076] In some embodiments, the clothes container is generally cylindrical.

[0077] In some embodiments, the outer barrel is generally cylindrical.

[0078] In some embodiments, the axis of rotation of the garment drum can be horizontal. That is, the garment handling equipment can be a drum-type garment handling equipment.

[0079] For example, the clothes drum may have an outlet, and there is a space between the clothes drum and the outer drum, with the outlet connecting the clothes processing chamber and the space. Taking a clothes processing device with a washing function as an example, the outer drum can be used to hold water, and the liquid can flow between the clothes processing chamber and the space through the outlet. Taking a clothes processing device with a drying function as an example, gas can flow between the clothes processing chamber and the space through the outlet.

[0080] In some embodiments, please refer to Figure 1 and Figure 2 The inner bottom surface of the container is equipped with a reinforcing seat 500. The rotation axis of the clothes tub extends horizontally. A first connecting part 131 connects to the bottom of the tub assembly 200, such as the outer tub, and a second connecting part 141 connects to the reinforcing seat 500. For example, a mounting base 300 is fixed to the reinforcing seat 500. The reinforcing seat 500 strengthens the structural strength of the container, increases its rigidity, and reduces vibrations.

[0081] In some embodiments, the sleeve 132, friction rod 133, and adapter 140 are all rigid structures. That is, the sleeve 132, friction rod 133, and adapter 140 do not deform significantly under the forces generated during the operation of the barrel assembly 200.

[0082] For example, the sleeve 132, friction rod 133 and adapter 140 can all be made of metal or steel with high rigidity.

[0083] The third vibration isolator 150, the second vibration isolator 120, and the first vibration isolator 110 can all be flexible structures. That is to say, the third vibration isolator 150, the second vibration isolator 120, and the first vibration isolator 110 can all deform under the force generated during the operation of the barrel assembly 200, thereby consuming vibration energy.

[0084] Both the third vibration isolator 150 and the first vibration isolator 110 can be made of nitrile rubber.

[0085] The second vibration isolator 120 can be made of high-damping rubber. For example, high-damping rubber is natural rubber with added compounding agents to improve the damping characteristics of the rubber. This can increase hysteresis loss and reduce storage modulus, thereby improving vibration absorption performance.

[0086] In some embodiments, please refer to Figure 1 The number of vibration damping devices 100 is even, and they are evenly distributed along the left-right direction at the bottom of the outer tub. For example, four vibration damping devices 100 are distributed in pairs along the left-right direction. This achieves uniform force distribution, maximizes the vibration damping effect, and reduces the vibration and noise generated by the garment processing equipment.
