[0017] In some embodiments, the adapter includes two bases, each base having a positioning portion and a fixing buckle. The positioning portions of the two bases pass through the positioning holes from both sides in a first direction, and the fixing buckles of the two bases are fixedly connected.

[0021] In some embodiments, the sleeve has a receiving cavity and a sliding channel extending axially along the friction rod.

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.

[0039] Please see Figures 2 to 4 This application provides a vibration damping device 100 for use in clothing processing equipment. The vibration damping device 100 includes a vibration isolation assembly 110, a sleeve 120, a friction rod 130, and an adapter 140.

[0040] Please continue reading. Figures 2 to 4 The first end of the friction rod 130 along its axial direction is slidably inserted into the sleeve 120. The second end of the friction rod 130 along its axial direction is connected to the adapter 140, and a vibration isolation component 110 is provided at the connection between the second end of the friction rod 130 and the adapter 140.

[0041] The vibration damping device 100 can connect to two components of the garment processing equipment that require vibration damping. The sleeve 120 and the adapter 140 are respectively used to connect to the two components of the garment processing equipment.

[0042] The first end of the friction rod 130 is inserted into the sleeve 120 and can slide along the axial direction of the friction rod 130 within the sleeve 120. That is, the friction rod 130 can perform linear reciprocating motion along the axial direction of the friction rod 130 within the sleeve 120. In this way, the frictional damping between the friction rod 130 and the sleeve 120 converts the vibration energy from the component into internal energy, thereby achieving the purpose of vibration reduction.

[0043] 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.

[0044] One of the sleeve 120 and the adapter 140 is connected to the barrel assembly 200, and the other of the sleeve 120 and the adapter 140 is connected to the box body. Exemplarily, in some embodiments, if the sleeve 120 is connected to the barrel assembly 200, then the adapter 140 is connected to the box body. In other embodiments, if the adapter 140 is connected to the barrel assembly 200, then the sleeve 120 is connected to the box body.

[0045] During operation, such as when the garment processing equipment 200 is processing garments, the 200 vibrates due to shaking. The magnitude of this vibration is primarily determined by the total system mass, the system's balance, and the damping force of the vibration damping device 100. To achieve optimal vibration reduction while keeping the total system mass and balance constant, the damping force of the vibration damping device 100 is often increased. However, increasing the damping force of the vibration damping device 100 increases the impact force it exerts on the internal system and the housing, ultimately leading to increased noise.

[0046] The vibration damping device 100 provided in this application embodiment uses vibrations generated during the operation of the tub assembly 200 to drive the sleeve 120 and friction rod 130 to slide relative to each other. This relative sliding of the sleeve 120 and friction rod 130 generates frictional damping force, achieving vibration reduction. The damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 is transmitted through the vibration isolation component 110 to the adapter 140, and then through the adapter 140 to either the tub assembly 200 or the housing. In this way, the adapter 140 extends the transmission path of the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120. After being damped and buffered by the vibration isolation component 110, the damping force is transmitted to the adapter 140. The impact energy of the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 is attenuated, thereby effectively reducing the vibration of the entire machine during operation, ultimately reducing overall machine noise, reducing noise pollution to the surrounding environment, and improving user comfort.

[0047] In one embodiment, please refer to Figures 2 to 4 The vibration isolation assembly 110 includes a first vibration isolator 111, and a sleeve 120 has a first connecting portion 121, on which the first vibration isolator 111 is disposed. The first connecting portion 121 is used to connect with components of the garment processing equipment. For example, the first connecting portion 121 is used to connect with the tub assembly 200 or the box. The first vibration isolator 111 is located on the transmission path of the friction damping force between the friction rod 130 and the sleeve 120. The friction damping force between the friction rod 130 and the sleeve 120 is transmitted to the tub assembly 200 or the box after being damped and buffered by the first vibration isolator 111. The first vibration isolator 111 can play a vibration damping role through its own deformation, thereby reducing the vibration noise at the connection between the first connecting portion 121 and the component.

[0048] In one embodiment, please refer to Figures 2 to 4 The vibration isolation assembly 110 includes a second vibration isolator 112, and the adapter 140 has a second connecting portion 141, on which the second vibration isolator 112 is disposed. The second connecting portion 141 is used to connect with components of the garment processing equipment. For example, the second connecting portion 141 is used to connect with the tub assembly 200 or the housing. The second vibration isolator 112 is located on the transmission path of the friction damping force between the friction rod 130 and the sleeve 120. The damping force from the adapter 140 is transmitted to the tub assembly 200 or the housing after being damped and buffered by the second vibration isolator 112. The second vibration isolator 112 can play a vibration damping role through its own deformation, thereby reducing the vibration noise at the connection between the second connecting portion 141 and the component. The damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 is transmitted to the adapter 140 through the vibration isolation component 110, and then to the second vibration isolation component 112 through the adapter 140, and finally to one of the barrel assembly 200 and the box, thus playing a secondary vibration isolation role.

[0049] In one embodiment, please refer to Figures 2 to 4 The vibration isolation assembly 110 includes a third vibration isolation element 113. The third vibration isolation element 113 is disposed at the connection between the second end of the friction rod 130 and the adapter 140. The third vibration isolation element 113 is located on the transmission path of the friction damping force between the friction rod 130 and the sleeve 120. The friction damping force is transmitted to the adapter 140 after being isolated and buffered by the third vibration isolation element 113. The third vibration isolation element 113 can play a vibration isolation and buffering role through its own deformation.

[0050] In some embodiments, please refer to Figures 2 to 4The first vibration isolator 111, the second vibration isolator 112, and the third vibration isolator 113 are all located on the transmission path of the friction damping force between the friction rod 130 and the sleeve 120. That is, the friction damping force between the friction rod 130 and the sleeve 120 is transmitted after being damped by the first vibration isolator 111, the second vibration isolator 112, and the third vibration isolator 113. The first vibration isolator 111, the second vibration isolator 112, and the third vibration isolator 113 can all dissipate vibration energy through their own deformation, thus playing a buffering and damping role. The damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 is transmitted through the third vibration isolator 113 to the adapter 140, then through the adapter 140 to the second vibration isolator 112, and finally to one of the barrel assembly 200 and the box body, thus achieving a secondary vibration isolation effect. In this way, through multiple buffering and vibration isolation by the first vibration isolation component 111, the second vibration isolation component 112 and the third vibration isolation component 113, the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 is absorbed and buffered multiple times, and the impact energy from the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 will be greatly attenuated, thereby effectively reducing the vibration of the whole machine when the garment processing equipment is working.

[0051] One of the first connecting portion 121 and the second connecting portion 141 is connected to the barrel assembly 200, and the other of the first connecting portion 121 and the second connecting portion 141 is connected to the box body. Exemplarily, in some embodiments, if the first connecting portion 121 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 121 is connected to the box body.

[0052] 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.

[0053] 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.

[0054] In some embodiments, the adapter 140, for example, the second connecting portion 141, is connected to the component with the greater vibration response among the two components. For example, if the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 has a greater impact on the housing, resulting in more noticeable noise from the housing, then the sleeve 120, for example, the first connecting portion 121, is connected to the barrel assembly 200, and the adapter 140, for example, the second connecting portion 141, is connected to the housing. In this way, the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 is transmitted to the housing after two stages of vibration damping by the second vibration isolator 112 and the third vibration isolator 113, which can reduce the impact of the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 on the housing and significantly improve the overall noise level. Conversely, if the damping force generated by the sliding of the friction rod 130 relative to the sleeve 120 has a greater impact on the barrel assembly 200, then the sleeve 120, for example, the first connecting part 121, is connected to the box body, and the adapter 140, for example, the second connecting part 141, is connected to the barrel assembly 200.

[0055] In one embodiment, please refer to Figure 2 and Figure 4 The first connecting portion 121 has a first hinge hole 121a extending along a first direction. At least a portion of the first vibration damping member 111 is disposed within the first hinge hole 121a, wherein the first direction is perpendicular to the axial direction of the friction rod 130. The first hinge hole 121a 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 first hinge hole 121a, 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.

[0056] As an example, in one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The first vibration isolator 111 has a first pin hole 111a extending in the first direction. Both the barrel assembly 200 and the box are provided with mounting bases 300. The mounting bases 300 have mounting holes extending in the first direction. The first connecting part 121 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 111a.

[0057] In some embodiments, the first hinge hole 121a penetrates both ends of the first end of the sleeve 120 along the first direction. The first vibration isolator 111 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 111a penetrates both ends of the mounting post along the first direction. The mounting post passes through the first hinge hole 121a, and the two annular protrusions are located at both ends of the first hinge hole 121a along the first direction. For example, the mounting post can be a circular post. Thus, the two annular protrusions prevent the first vibration isolator 111 from dislodging from the first hinge hole 121a.

[0058] In one embodiment, please refer to Figure 1 , Figure 4 and Figure 6 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 112 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.

[0059] As an example, in one embodiment, please refer to Figure 1 and Figure 4 The second vibration isolator 112 has a second pin hole 112a 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 112a.

[0060] In one embodiment, please refer to Figure 4 and Figure 6 The vibration damping device includes a wear-resistant bushing 160, which is sleeved on the connecting pin 400 and passes through the second pin hole 112a. The wear-resistant bushing 160 has good wear resistance, which can reduce the wear of the connecting pin 400 on the second vibration isolator 112, thereby improving the service life of the vibration damping device 100.

[0061] In some embodiments, the second hinge hole 141a penetrates both ends of the adapter 140 along the first direction. The second vibration isolator 112 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 112a 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 the two 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 112 from dislodging from the second hinge hole 141a.

[0062] 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 111a to prevent the connecting pin 400 from falling off.

[0063] 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 111a as an example, during the process of the tapered head passing through the mounting hole and the first pin hole 111a, the hole wall of the mounting hole and the hole wall of the first pin hole 111a force the resilient boss to retract from the groove, so that the resilient boss moves to the side of the first connecting part 121 away from the screw head. The force applied to the hole wall of the mounting hole and the hole wall of the first pin hole 111a is removed, the resilient boss protrudes from the groove, and the mounting seat 300 and the first connecting part 121 are clamped between the screw head and the resilient boss.

[0064] In one embodiment, the second end of the friction rod 130 is fixed to the adapter 140. That is, the friction rod 130 and the adapter 140 do not rotate relative to each other. Thus, during the operation of the barrel assembly 200, there will be no relative rotation between the second end of the friction rod 130 and the adapter 140, so as to avoid the connection between the second end of the friction rod 130 and the adapter 140 impacting the box.

[0065] In one embodiment, please refer to Figures 4 to 6The second end of the friction rod 130 has a connecting hole 130a extending in the first direction. The adapter 140 has a positioning part 142, and the third vibration isolator 113 has a positioning hole 113a extending in the first direction. At least a portion of the third vibration isolator 113 is disposed within the connecting hole 130a, and the positioning part 142 passes through the positioning hole 113a. By using the connection method of the positioning part 142 and the positioning hole 113a, the connection method between the second end of the friction rod 130 and the adapter 140 is simple. This not only facilitates the assembly of the friction rod 130, the third vibration isolator 113, and the adapter 140, but also facilitates the transmission of force between the friction rod 130 and the adapter 140. The third vibration isolator 113 is disposed between the positioning part 142 and the hole wall of the connecting hole 130a. The damping force is absorbed by the third vibration isolator 113 and then transmitted to the positioning part 142.

[0066] In some embodiments, the connecting hole 130a penetrates both ends of the second end of the friction rod 130 along the first direction. The third vibration isolator 113 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 113a penetrates both ends of the column along the first direction. The column passes through the connecting hole 130a, and 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 third vibration isolator 113 from coming out of the connecting hole 130a.

[0067] In some embodiments, the positioning part 142 is interference-fitted with the positioning hole 113a. This reduces the movement of the positioning part 142 within the positioning hole 113a to a certain extent.

[0068] In one embodiment, please refer to Figures 4 to 7 The adapter 140 has two limiting portions 143, which are spaced apart along a second direction. At least a portion of the second end of the friction rod 130 is located between the two limiting portions 143, wherein the first direction, the second direction, and the axial direction of the friction rod 130 are perpendicular to each other. The two limiting portions 143 can limit the rotation angle of the friction rod 130 about the positioning portion 142, and can prevent the second end of the friction rod 130 from hitting the housing at the connection between the adapter 140 and the adapter. In this way, by limiting the rotation of the friction rod 130 relative to the adapter 140 by the two limiting portions 143 on the adapter 140, it is not necessary to constrain the second end of the adapter 140 and the friction rod 130 by other components.

[0069] In one embodiment, please refer to Figures 5 to 7The second end of the friction rod 130 includes a connector 131 and a protrusion 132. The protrusion 132 is connected to the end of the connector 131 away from the sleeve 120. The connector 131 has a connecting hole 130a. The limiting part 143 includes limiting ribs 1431, and the limiting ribs 1431 of the two limiting parts 143 are located on both sides of the protrusion 132 along the second direction. The protrusion 132 is located on the outer periphery of the connector 131 away from the positioning part 142. If the connector 131 deflects around the positioning part 142, the rotation arc of the protrusion 132 is larger than that of other parts of the connector 131. Therefore, by using the two limiting ribs 1431 to clamp the protrusion 132 to limit the deflection of the protrusion 132 around the positioning part 142, the deflection of the connector 131 around the positioning part 142 can be better limited, so that the possible deflection angle of the second end of the friction rod 130 is as small as possible.

[0070] The shapes of the two sides of the protrusion 132 along the second direction are adapted to the sides of the limiting rib 1431 facing the connector 131. In one embodiment, please refer to... Figure 7 The protrusion 132 has two concave arc-shaped sides along the second direction, and the limiting rib 1431 has a convex arc-shaped side facing the protrusion 132. Thus, the distance between the side of the protrusion 132 along the second direction and the side of the limiting rib 1431 facing the connector 131 is consistent; for example, the distance between the side of the protrusion 132 along the second direction and the side of the limiting rib 1431 facing the connector 131 is between 0.1 mm and 0.2 mm. In this way, the protrusion 132 can be fitted between the two limiting ribs 1431, and the two sides of the protrusion 132 along the second direction cooperate with the limiting ribs 1431 to limit the second end of the friction rod 130 from deflecting around the positioning part 142.

[0071] In one embodiment, please refer to Figures 5 to 7 The limiting part 143 includes a side rib 1432, which is connected to the end of the limiting rib 1431 near the sleeve 120. The side ribs 1432 of the two limiting parts 143 are located on both sides of the connector 131 along the second direction. The side ribs 1432 are used to provide auxiliary limiting constraints on the connector 131, further improving the constraint on the deflection of the second end of the friction rod 130 around the positioning part 142.

[0072] The shapes of the two sides of the connector 131 along the second direction are adapted to the sides of the side rib 1432 facing the connector 131. In one embodiment, please refer to... Figure 7The connector 131 has two outwardly protruding convex arc shapes on its two sides along the second direction, while the side ribs 1432 have concave arc shapes on their sides facing the connector 131. The distance between the sides of the connector 131 along the second direction and the sides of the side ribs 1432 facing the connector 131 is consistent; for example, the distance between the sides of the connector 131 along the second direction and the sides of the side ribs 1432 facing the connector 131 is between 0.1 mm and 0.2 mm. In this way, the connector 131 can be fitted between the two side ribs 1432, and the two sides of the connector 131 along the second direction cooperate with the side ribs 1432 to limit the deflection of the second end of the limiting friction rod 130 around the positioning part 142.

[0073] In one embodiment, please refer to Figures 4 to 7 The adapter 140 includes two bases 140', each base 140' having a positioning part 142 and a fixing buckle 144. The positioning parts 142 of the two bases 140' are respectively inserted into the positioning holes 113a from both sides in the first direction, and the fixing buckles 144 of the two bases 140' are fixedly connected. On the one hand, the two bases 140' have the same structural shape, making them easy to manufacture as standard parts and reducing costs. On the other hand, the positioning parts 142 of the two bases 140' are inserted into the positioning holes 113a from both sides in the first direction, and the fixing buckles 144 of the two bases 140' are fixedly connected. In this way, both the two bases 140' can be fixed, and the adapter 140 and the friction rod 130 can be assembled. The assembly method is simple and easy to operate.

[0074] In one embodiment, please refer to Figures 4 to 7 The base 140' has a second connecting portion 141. The second hinge hole 141a of the second connecting portion 141 is aligned and connected.

[0075] In one embodiment, the positioning part 142 is formed with a clearance hole, a portion of the fixing buckle 144 is located in the clearance hole and the other portion of the fixing buckle 144 extends out of the clearance hole. In this way, the space inside the positioning part 142 is used to accommodate the fixing buckle 144, resulting in a compact structure, while the other portion of the fixing buckle 144 extending out of the clearance hole can prevent the fixing buckle 144 from interfering with the positioning part 142 of the two bases 140' passing through the positioning hole 113a.

[0076] In one embodiment, the fastener 144 includes an arm body and a fastening portion. The fastening portion extends from one side of the arm body in a second direction, and the fastening portions of the two bases 140' are stacked and engaged along a first direction. That is, the fastener 144 is approximately L-shaped. Exemplarily, the two bases 140' move towards each other along the first direction, and the contact of the two fastening portions forces the arm body to undergo elastic deformation. This elastic deformation allows the fastening portion of one base 140' to move from one side to the other. The stacking of the fastening portions of the two bases 140' along the first direction allows the arm body to regain its elastic deformation, and the opposing end faces of the two bases 140' abut against each other along the first direction. Thus, the fastening portions of the two bases 140' are stacked and engaged along the first direction. The fastener 144 has a simple structure and a simple assembly method.

[0077] In one embodiment, please refer to Figures 6 to 7 The substrate 140' forms a limiting hole 1401 and a limiting protrusion 1402, and the limiting protrusions 1402 and limiting holes 1401 of the two substrates 140' are inserted into each other in a one-to-one correspondence. Specifically, the limiting hole 1401 of one substrate 140' and the limiting protrusion 1402 of the other substrate 140' together form a limiting pair, and the limiting hole 1401 and the limiting protrusion 1402 of the limiting pair are inserted into each other. That is to say, the limiting hole 1401 of one substrate 140' is inserted into the limiting protrusion 1402 of the other substrate 140', and the two substrates 140' include at least two limiting pairs. On the one hand, the limiting protrusion 1402 and the limiting hole 1401 play a positioning and assembly role during the assembly of the two bases 140'; on the other hand, the limiting protrusion 1402 and the limiting hole 1401 of each base 140' are not on a straight line extending along the first direction, and the limiting protrusion 1402 and the limiting hole 1401 of the two bases 140' are inserted one-to-one, which can further restrict the relative rotation of the two bases 140', making the connection between the two bases 140' more stable.

[0078] In one embodiment, please refer to Figures 6 to 7 The limiting holes 1401 and limiting protrusions 1402 of each substrate 140' are arranged at intervals along the second direction. In this way, the multiple limiting pairs are arranged at intervals along the second direction, which can restrict the relative rotation of the two substrates 140'.

[0079] The shapes of the limiting hole 1401 and the limiting protrusion 1402 are not limited. In one embodiment, please refer to [reference needed]. Figures 6 to 7 The limiting hole 1401 is circular in shape, and the limiting protrusion 1402 is cylindrical.

[0080] In one embodiment, please refer to Figures 6 to 7The base 140' includes an adapter plate 1403, which has a second hinge hole 141a. Two limiting portions 143 are connected to the side of the adapter plate 1403 along the first direction to jointly define a mounting groove 1403a that opens toward the axial side of the friction rod 130. A positioning portion 142 is connected to the adapter plate 1403 and located between the two limiting portions 143. A connector 131 is located within the mounting groove 1403a. Thus, the structure of the base 140' is simple, and the adapter plates 1403 of the two bases 140' can prevent the friction rod 130 from dislodging from the mounting groove 1403a along the first direction.

[0081] In one embodiment, the second vibration isolator 112 and the third vibration isolator 113 have at least one different vibration isolation parameter, which includes stiffness, damping characteristics, and thickness. The rate of attenuation of vibration energy in structures with different thicknesses, stiffness, and / or damping characteristics is greater than that in structures with uniform thickness, stiffness, and damping characteristics. Therefore, the fact that the first vibration isolator 111 and the second vibration isolator 112 have at least one different vibration isolation parameter can achieve attenuation of vibration transmission. During use, clothing and / or water entering the tank assembly 200 causes changes in the weight of the tank assembly 200. The tank assembly 200 vibrates in multiple directions, including left-right and up-down, during operation. These weight and positional changes can alter the vibration frequency. Furthermore, the use of different vibration isolation parameters in the third and second vibration isolation components 113 and 112 can absorb more vibration energy, increasing energy loss during transmission. Therefore, by designing different vibration isolation parameters for the third and second vibration isolation components 113 and 112, they can absorb vibrations of different frequencies, effectively reducing vibration over a wider frequency range to accommodate the vibrations generated by the tank assembly 200 and the housing.

[0082] In one embodiment, the thickness of the second vibration isolator 112 is greater than the thickness of the third vibration isolator 113. Thus, the second vibration isolator 112 has a stronger vibration absorption capacity than the third vibration isolator 113, further reducing the damping force transmitted to the component connected to the second connection portion 141.

[0083] In one embodiment, the hardness of the second vibration isolator 112 is less than that of the third vibration isolator 113. The third vibration isolator 113 and the second vibration isolator 112 are connected in series in the vibration transmission path. The second vibration isolator 112 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 third vibration isolator 113 and the second vibration isolator 112 in sequence. The second vibration isolator 112 has a relatively lower hardness and a lower vibration transmission rate than the third vibration isolator 113. In this way, the situation where the compression of one of the third vibration isolator 113 and the second vibration isolator 112 is too large can be avoided. This 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 third vibration isolator 113 and the second vibration isolator 112.

[0084] In one embodiment, the second vibration isolator 112 is a damped vibration isolator, and the third vibration isolator 113 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 112 is a damped vibration isolator, which can further absorb more vibration energy and reduce noise.

[0085] In one embodiment, at least one vibration isolation parameter is the same for both the first vibration isolator 111 and the third vibration isolator 113, including stiffness, damping characteristics, and thickness. This facilitates the even transmission of the damping force generated by the sleeve 120 and the friction rod 130 to the first vibration isolator 111 and the third vibration isolator 113.

[0086] In one exemplary embodiment, the first vibration isolator 111 and the third vibration isolator 113 have the same structure and vibration isolation parameters. The third vibration isolator 113 has a thickness of 3 mm and a hardness of 70 A, and is an undamped vibration isolator. The second vibration isolator 112 has a thickness of 5 mm and a hardness of 55 A, and is a damped vibration isolator. Using this vibration isolation component 110, the noise reduction effect on different platforms can reach more than 1.2 dB.

[0087] In one embodiment, please refer to Figure 4 The vibration damping device 100 includes a friction damping element 150, which is disposed between the friction rod 130 and the sleeve 120. The friction damping element 150 and the friction rod 130 slide relative to each other. That is, the friction damping element 150 and the sleeve 120 remain relatively stationary, and the friction between the friction rod 130 and the friction damping element 150 generates a damping force. The friction damping element 150 can increase the damping coefficient of the sleeve 120, thereby increasing the damping force between the friction rod 130 and the sleeve 120.

[0088] In one embodiment, please refer to Figure 4 The friction damping element 150 is disposed inside the sleeve 120. The friction damping element 150 has through holes extending through its two end faces along the first direction, and the friction rod 130 is slidably inserted into the through holes. The friction damping element 150 has a generally annular structure, which is simple in structure and easy to manufacture.

[0089] For example, in some embodiments, the friction damper 150 is generally annular and the friction rod 130 is a circular rod.

[0090] In one embodiment, please refer to Figure 4 The sleeve 120 has a receiving cavity 120a and a sliding channel 120b extending axially along the friction rod 130. The receiving cavity 120a surrounds the outer periphery of the sliding channel 120b. The second end of the sleeve 120 has an insertion port 120c communicating with the sliding channel 120b. The first end of the friction rod 130 is inserted into the sliding channel 120b through the insertion port 120c. The friction damping element 150 is sleeved on the friction rod 130 and accommodated in the receiving cavity 120a. The cavity wall of the receiving cavity 120a restricts the movement of the friction damping element 150 along the axial direction of the friction rod 130.

[0091] In one embodiment, please refer to Figure 3 and Figure 4 The first end of the sleeve 120 has a first connecting portion 121. The receiving cavity 120a is located at the second end of the sleeve 120. With this design, the length of the sleeve 120 in the first direction can be relatively short while satisfying the sliding stroke of the friction rod 130 in the first direction, so as to facilitate the assembly of the vibration damping device 100 in the limited installation space inside the housing.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] In some embodiments, the clothes container is generally cylindrical.

[0097] In some embodiments, the outer barrel is generally cylindrical.

[0098] 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.

[0099] 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.

[0100] 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 121 connects to the bottom of 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.

[0101] In some embodiments, the sleeve 120, friction rod 130, and adapter 140 are all rigid structures. That is, the sleeve 120, friction rod 130, and adapter 140 do not deform significantly under the forces generated during the operation of the barrel assembly 200.

[0102] For example, the sleeve 120, friction rod 130 and adapter 140 can all be made of metal or steel with high rigidity.

[0103] The first vibration isolation member 111, the second vibration isolation member 112, and the third vibration isolation member 113 can all be flexible structures. That is to say, the first vibration isolation member 111, the second vibration isolation member 112, and the third vibration isolation member 113 can all deform under the force generated during the operation of the barrel assembly 200, thereby consuming vibration energy.

[0104] Both the first vibration isolator 111 and the third vibration isolator 113 can be made of nitrile rubber.

[0105] The second vibration isolator 112 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.

[0106] 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.
