The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please see Figures 2 to 4 This application provides a vibration damping device 100 for clothing processing equipment. The vibration damping device 100 includes a vibration damper 110, a first vibration isolation member 120, and an adapter 130.

[0039] Please continue reading. Figures 4 to 6 The vibration damper 110 has a connecting hole 110a. The first vibration isolator 120 has a positioning hole 120a, and at least a portion of the first vibration isolator 120 is disposed within the connecting hole 110a. The adapter 130 has a positioning part 132, which passes through the positioning hole 120a.

[0040] The vibration damping device 100 can be connected to two components of the garment processing equipment that require vibration damping. The vibration damper 110 is capable of generating a damping force for damping vibration reduction.

[0041] As an example, in one embodiment, please refer to Figures 4 to 6The shock absorber 110 has a first connecting portion 111, and the adapter 130 has a second connecting portion 131. The first connecting portion 111 and the second connecting portion 131 are respectively used to connect to two components of the garment processing equipment.

[0042] For example, the damper 110 can generate a frictional damping force to reduce vibration through frictional damping.

[0043] Please see Figure 1 and Figure 2 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. One of the vibration damper 110 and the adapter 130 is connected to the drum assembly 200, and the other of the vibration damper 110 and the adapter 130 is connected to the housing.

[0044] For example, one of the first connecting portion 111 and the second connecting portion 131 is connected to the barrel assembly 200, and the other of the first connecting portion 111 and the second connecting portion 131 is connected to the box body. For example, in some embodiments, if the first connecting portion 111 is connected to the barrel assembly 200, then the second connecting portion 131 is connected to the box body. In other embodiments, if the second connecting portion 131 is connected to the barrel assembly 200, then the first connecting portion 111 is connected to the box body.

[0045] 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.

[0046] 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.

[0047] 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 damper 110. To achieve optimal vibration reduction while keeping the total system mass and balance constant, increasing the damping force of the vibration damper 110 is often used. However, increasing the damping force of the vibration damper 110 increases the impact force it exerts on the internal system and the housing, ultimately leading to increased noise.

[0048] The vibration damping device 100 provided in this application embodiment has several advantages. First, it uses a connection method between the positioning part 132 and the positioning hole 120a. The connection method between the vibration damper 110 and the adapter 130 is simple, which not only facilitates the assembly of the vibration damper 110, the first vibration isolation member 120, and the adapter 130, but also facilitates the transmission of force between the vibration damper 110 and the adapter 130. Second, it achieves damping vibration reduction by generating damping force through the vibration damper 110. The first vibration isolation member 120 is disposed between the positioning part 132 and the hole wall of the connecting hole 110a. The damping force generated by the vibration damper 110 is buffered and isolated by the first vibration isolation member 120 and then transmitted to the adapter 130, and then transmitted to the box or barrel assembly 200 through the adapter 130. In this way, the impact energy of the damping force from the vibration damper 110 will be attenuated, thereby 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.

[0049] In one embodiment, please refer to Figure 2 The vibration damping device 100 includes a second vibration isolation member 140 and a third vibration isolation member 150. The first connecting part 111 is provided with the third vibration isolation member 150, and the second connecting part 131 is provided with the second vibration isolation member 140.

[0050] The first vibration isolator 120, the second vibration isolator 140, and the third vibration isolator 150 are all located on the transmission path of the damping force of the vibration damper 110. That is, the damping force of the vibration damper 110 is transmitted after being damped by the first vibration isolator 120, the second vibration isolator 140, and the third vibration isolator 150. The first vibration isolator 120, the second vibration isolator 140, and the third vibration isolator 150 can all dissipate vibration energy through their own deformation, thus playing a buffering and damping role.

[0051] In this embodiment, the damping force generated by the vibration damper 110 is buffered and isolated by the third vibration isolator 150 and then transmitted to one of the tub assembly 200 and the housing. The damping force generated by the vibration damper 110 is transmitted to the adapter 130 through the first vibration isolator 120, then to the second vibration isolator 140 through the adapter 130, and finally to the other of the tub assembly 200 and the housing, thus achieving a secondary vibration isolation effect. In this way, through multiple buffering and vibration isolation by the third vibration isolator 150, the second vibration isolator 140, and the first vibration isolator 120, the damping force generated by the vibration damper 110 is absorbed and buffered multiple times, and the impact energy from the damping force is greatly attenuated, thereby effectively reducing the vibration of the entire machine when the clothing processing equipment is working, and ultimately reducing the overall machine noise.

[0052] In one embodiment, please refer to Figure 1 and Figure 2The first connecting portion 111 has a first hinge hole 111a, and at least a portion of the third vibration isolator 150 is disposed within the first hinge hole 111a. The first hinge hole 111a 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 will change. Therefore, the vibration damping device 100 is rotatably connected to the component through the first hinge hole 111a, 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.

[0053] In one embodiment, please refer to Figure 1 and Figure 6 The second connecting portion 131 has a second hinge hole 131a, and at least a portion of the second vibration isolator 140 is disposed within the second hinge hole 131a. The second hinge hole 131a is used for rotatable connection with a component, such as the bucket assembly 200 or the box. Because clothing and / or water entering the bucket assembly 200 causes a change in the weight of the bucket assembly 200, the position of the bucket assembly 200 in the vertical direction will change. Therefore, the vibration damping device 100 is rotatably connected to the component through the second hinge hole 131a, allowing the vibration damping device 100 and the component, such as the bucket 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 bucket assembly 200, and further absorbing vibration energy through rotation.

[0054] In some embodiments, the second connecting portion 131 is connected to the component with the greater vibration response of the two components. For example, if the damping force has a greater impact on the housing, resulting in more noticeable overall noise from the housing, then the first connecting portion 111 is connected to the barrel assembly 200, and the second connecting portion 131 is connected to the housing. In this way, the damping force is transmitted to the housing after two stages of vibration reduction via the first vibration isolator 120 and the second vibration isolator 140, which can reduce the impact of the damping force on the housing and significantly improve the overall noise level. Conversely, if the damping force has a greater impact on the barrel assembly 200, then the first connecting portion 111 is connected to the housing, and the second connecting portion 131 is connected to the barrel assembly 200.

[0055] In one embodiment, please refer to Figures 2 to 6The vibration damper 110 includes a sleeve 112 and a friction rod 113. The sleeve 112 has a first connecting portion 111. A first end of the friction rod 113 along its axial direction is slidably inserted into the sleeve 112, and a second end of the friction rod 113 along its axial direction has a connecting hole 110a extending along a first direction, which is perpendicular to the axial direction of the friction rod 113. The first end of the friction rod 113 is inserted into the sleeve 112 and can slide along its axial direction within the sleeve 112. That is, the friction rod 113 can perform linear reciprocating motion along its axial direction within the sleeve 112. Thus, the frictional damping between the friction rod 113 and the sleeve 112 converts the vibration energy from the component into internal energy, achieving vibration reduction.

[0056] In some embodiments, both the first hinge hole 111a and the second hinge hole 131a extend along a first direction.

[0057] As an example, in one embodiment, please refer to Figures 1 to 4 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 seats 300. The mounting seats 300 have mounting holes extending in the first direction. The first connecting part 111 is located in the mounting hole of one of the mounting seats 300 of the barrel assembly 200 and the mounting seats 300 of the box. The connecting pin 400 passes through the mounting hole and the first pin hole 150a.

[0058] In some embodiments, the first hinge hole 111a penetrates the first end of the sleeve 112 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 111a, and the two annular protrusions are located at the two ends of the first hinge hole 111a 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 111a.

[0059] As an example, in one embodiment, please refer to Figures 1 to 4 The second vibration isolator 140 has a second pin hole 140a extending in the first direction. The second connecting part 131 is located in the mounting hole of one of the mounting base 300 of the barrel assembly 200 and the mounting base 300 of the box body. The connecting pin 400 passes through the mounting hole and the second pin hole 140a.

[0060] In one embodiment, please refer to Figures 4 to 6The vibration damping device 100 includes a wear-resistant bushing 160, which is sleeved on the connecting pin 400 and passes through the second pin hole 140a. The wear-resistant bushing 160 has good wear resistance, which can reduce the wear of the connecting pin 400 on the second vibration isolator 140, thereby improving the service life of the vibration damping device 100.

[0061] In some embodiments, the second hinge hole 131a penetrates both ends of the adapter 130 along the first direction. The second vibration isolator 140 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 140a penetrates both ends of the cylindrical portion along the first direction. The cylindrical portion passes through the second hinge hole 131a, and the two annular protrusions are located at both ends of the second hinge hole 131a along the first direction. For example, the cylindrical portion is generally cylindrical. Thus, the two annular protrusions prevent the second vibration isolator 140 from dislodging from the second hinge hole 131a.

[0062] The connecting pin 400 can be a self-locking pin. For example, the connecting pin 400 can self-lock after being inserted into the first pin hole 150a or the second pin hole 140a, so as 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 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 portion 111 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 portion 111 are clamped between the screw head and the resilient boss.

[0064] In one embodiment, the second end of the friction rod 113 is fixed to the adapter 130. That is, the friction rod 113 and the adapter 130 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 113 and the adapter 130, so as to avoid the connection between the second end of the friction rod 113 and the adapter 130 impacting the box.

[0065] In some embodiments, the positioning part 132 is interference-fitted with the positioning hole 120a. This reduces the movement of the positioning part 132 within the positioning hole 120a to a certain extent.

[0066] In one embodiment, please refer to Figures 4 to 7 The adapter 130 has two limiting portions 133, which are spaced apart along a second direction. At least a portion of the second end of the friction rod 113 is located between the two limiting portions 133, wherein the first direction, the second direction, and the axial direction of the friction rod 113 are perpendicular to each other. The two limiting portions 133 can limit the rotation angle of the friction rod 113 about the positioning portion 132, and can prevent the second end of the friction rod 113 from hitting the housing at the connection between the adapter 130 and the adapter. In this way, by limiting the rotation of the friction rod 113 relative to the adapter 130 by the two limiting portions 133 on the adapter 130, it is not necessary to constrain the second end of the adapter 130 and the friction rod 113 by other components.

[0067] In one embodiment, please refer to Figures 4 to 7 The second end of the friction rod 113 includes a connector 1131 and a protrusion 1132. The protrusion 1132 is connected to the end of the connector 1131 away from the sleeve 112. The connector 1131 has a connecting hole 110a. The limiting part 133 includes a limiting rib 1331. The limiting ribs 1331 of the two limiting parts 133 are located on both sides of the protrusion 1132 along the second direction. The protrusion 1132 is located on the outer periphery of the connector 1131 away from the positioning part 132. If the connector 1131 deflects around the positioning part 132, the rotation arc of the protrusion 1132 is larger than that of other parts of the connector 1131. Therefore, by using two limiting ribs 1331 to clamp the protrusion 1132 to limit the deflection of the protrusion 1132 around the positioning part 132, the deflection of the connector 1131 around the positioning part 132 can be better limited, so that the deflection angle that the second end of the friction rod 113 may generate is as small as possible.

[0068] The shapes of the two sides of the protrusion 1132 along the second direction are adapted to the sides of the limiting rib 1331 facing the connector 1131. In one embodiment, the two sides of the protrusion 1132 along the second direction are concave arc shapes, and the sides of the limiting rib 1331 facing the protrusion 1132 are convex arc shapes. Thus, the distance between the sides of the protrusion 1132 along the second direction and the sides of the limiting rib 1331 facing the connector 1131 is consistent. For example, the distance between the sides of the protrusion 1132 along the second direction and the sides of the limiting rib 1331 facing the connector 1131 is between 0.1 mm and 0.2 mm. In this way, the protrusion 1132 can be fitted between the two limiting ribs 1331, and the two sides of the protrusion 1132 along the second direction cooperate with the limiting ribs 1331 to limit the second end of the friction rod 113 from deflecting around the positioning part 132.

[0069] In one embodiment, please refer to Figures 4 to 7The limiting part 133 includes a side rib 1332, which is connected to the end of the limiting rib 1331 near the sleeve 112. The side ribs 1332 of the two limiting parts 133 are located on both sides of the connector 1131 along the second direction. The side ribs 1332 are used to provide auxiliary limiting constraints on the connector 1131, further improving the constraint on the second end of the friction rod 113 deflecting around the positioning part 132.

[0070] The shapes of the two sides of the connector 1131 along the second direction are adapted to the sides of the side ribs 1332 facing the connector 1131. In one embodiment, the two sides of the connector 1131 along the second direction are convex arcs protruding outwards, and the sides of the side ribs 1332 facing the connector 1131 are concave arcs. The distance between the sides of the connector 1131 along the second direction and the sides of the side ribs 1332 facing the connector 1131 is consistent. For example, the distance between the sides of the connector 1131 along the second direction and the sides of the side ribs 1332 facing the connector 1131 is between 0.1 mm and 0.2 mm. In this way, the connector 1131 can be assembled between the two side ribs 1332, and the two sides of the connector 1131 along the second direction cooperate with the side ribs 1332 to limit the deflection of the second end of the friction rod 113 around the positioning part 132.

[0071] In one embodiment, please refer to Figures 4 to 7 The adapter 130 includes two bases 1300, each base 1300 having a positioning part 132 and a fixing buckle 134. Both the connecting hole 110a and the positioning hole 120a extend along a first direction. The positioning parts 132 of the two bases 1300 pass through the positioning holes 120a from both sides of the first direction, and the fixing buckles 134 of the two bases 1300 are fixedly connected. On one hand, the two bases 1300 have identical structural shapes, making them easy to manufacture as standard parts and reducing costs. On the other hand, the positioning parts 132 of the two bases 1300 are inserted into the positioning holes 120a from both sides of the first direction, and the fixing buckles 134 of the two bases 1300 are fixedly connected. Thus, both the two bases 1300 can be fixed, and the adapter 130 and the friction rod 113 can be assembled. The assembly method is simple and easy to operate.

[0072] As an example, in one embodiment, please refer to Figures 4 to 7 The base 1300 has a second connecting portion 131. The second hinge hole 131a of the second connecting portion 131 is aligned and connected.

[0073] In one embodiment, the positioning part 132 has a clearance hole, a portion of the fixing buckle 134 is located within the clearance hole, and the other portion of the fixing buckle 134 extends out of the clearance hole. In this way, the space within the positioning part 132 is used to accommodate the fixing buckle 134, resulting in a compact structure. Furthermore, the extension of the other portion of the fixing buckle 134 into the clearance hole prevents the fixing buckle 134 from interfering with the positioning parts 132 of the two bases 1300 passing through the positioning hole 120a.

[0074] In one embodiment, please refer to Figures 4 to 7 The fastener 134 includes an arm body 1341 and a fastening part 1342. The fastening part 1342 extends from the arm body 1341 towards the second direction. The fastening parts 1342 of the two bases 1300 are stacked and engaged along the first direction. That is to say, the fastener 134 is roughly L-shaped. For example, two bases 1300 move towards each other along a first direction. The contact of the two fastening portions 1342 forces the arm body 1341 to undergo elastic deformation. This elastic deformation allows the fastening portion 1342 of one base 1300 to move from one side of the fastening portion 1342 of the other base 1300 to the other side. The fastening portions 1342 of the two bases 1300 overlap along the first direction, causing the arm body 1341 to regain its elastic deformation. The end faces of the fastening portions 1342 of the two bases 1300 abut against each other along the first direction. Thus, the fastening portions 1342 of the two bases 1300 overlap and engage along the first direction. The fastening buckle 134 has a simple structure and a simple assembly method.

[0075] In one embodiment, please refer to Figures 6 to 7 The substrate 1300 forms a limiting hole 1300a and a limiting protrusion 1300b, and the limiting protrusions 1300b and limiting holes 1300a of the two substrates 1300 are inserted into each other in a one-to-one correspondence. Specifically, the limiting hole 1300a of one substrate 1300 and the limiting protrusion 1300b of the other substrate 1300 together form a limiting pair, and the limiting hole 1300a and the limiting protrusion 1300b of the limiting pair are inserted into each other. That is to say, the limiting hole 1300a of one substrate 1300 is inserted into the limiting protrusion 1300b of the other substrate 1300, and the two substrates 1300 include at least two limiting pairs. On the one hand, the limiting protrusion 1300b and the limiting hole 1300a play a positioning and assembly role during the assembly of the two bases 1300; on the other hand, the limiting protrusion 1300b and the limiting hole 1300a of each base 1300 are not on a straight line extending along the first direction, and the limiting protrusion 1300b and the limiting hole 1300a of the two bases 1300 are inserted one-to-one, which can further restrict the relative rotation of the two bases 1300, making the connection between the two bases 1300 more stable.

[0076] In one embodiment, please refer to Figures 6 to 7The limiting holes 1300a and limiting protrusions 1300b of each substrate 1300 are arranged at intervals along the second direction. In this way, the multiple limiting pairs arranged at intervals along the second direction can restrict the relative rotation of the two substrates 1300.

[0077] The shapes of the limiting hole 1300a and the limiting protrusion 1300b are not limited. In one embodiment, please refer to [reference needed]. Figures 6 to 7 The limiting hole 1300a is circular in shape, and the limiting protrusion 1300b is cylindrical.

[0078] In one embodiment, please refer to Figures 6 to 7 The base 1300 includes an adapter plate 135, which has a second hinge hole 131a. Two limiting portions 133 are connected to the side of the adapter plate 135 along the first direction to jointly define a mounting groove 135a that opens toward the axial side of the friction rod 113. A positioning portion 132 is connected to the adapter plate 135 and located between the two limiting portions 133. A connector 1131 is located within the mounting groove 135a. Thus, the structure of the base 1300 is simple, and the adapter plates 135 of the two bases 1300 can prevent the friction rod 113 from dislodging from the mounting groove 135a along the first direction.

[0079] In one embodiment, the first vibration isolator 120 and the second vibration isolator 140 have at least one different vibration isolation parameter, which includes stiffness, damping characteristics, and thickness. On the one hand, the rate of attenuation of vibration energy in structures with different thicknesses, stiffness, and / or damping characteristics is greater than the rate of attenuation in structures with uniform thickness, stiffness, and damping characteristics. Therefore, the fact that the first vibration isolator 120 and the second vibration isolator 140 have at least one different vibration isolation parameter can achieve attenuation of vibration transmission. On the other hand, during the use of the clothing processing equipment, the entry of clothing and / or water into the tub assembly 200 causes a change in the weight of the tub assembly 200. During operation, the tub assembly 200 will vibrate in multiple directions, such as left and right and up and down. The changes in the weight and position of the tub assembly 200 may cause changes in the vibration frequency. Moreover, in the vibration energy transmission path, the first vibration isolation component 120 and the second vibration isolation component 140 with different vibration isolation parameters can consume more vibration energy and increase the loss of vibration energy in the transmission path. Therefore, by designing different vibration isolation parameters for the first vibration isolation component 120 and the second vibration isolation component 140, the first vibration isolation component 120 and the second vibration isolation component 140 can absorb vibrations of different frequencies and effectively reduce vibrations over a wide frequency range in order to adapt to the vibrations generated by the tub assembly 200 and the box.

[0080] In one embodiment, at least one vibration isolation parameter is the same for both the third vibration isolator 150 and the first vibration isolator 120, including stiffness, damping characteristics, and thickness. This facilitates the even transmission of frictional damping force to the third vibration isolator 150 and the first vibration isolator 120.

[0081] In one exemplary embodiment, the third vibration isolator 150 and the first vibration isolator 120 have the same structure and vibration isolation parameters. The first vibration isolator 120 has a thickness of 3 mm and a stiffness of 70 A, and is an undamped vibration isolator. The second vibration isolator 140 has a thickness of 5 mm and a stiffness of 55 A, and is a damped vibration isolator. Using this vibration isolation assembly, the noise reduction effect on different platforms can reach more than 1.2 dB.

[0082] In one embodiment, please refer to Figure 4 The vibration damper 110 includes a friction damping element 114, which is disposed between the friction rod 113 and the sleeve 112. The friction damping element 114 and the friction rod 113 slide relative to each other. That is, the friction damping element 114 and the sleeve 112 remain relatively stationary, and the friction between the friction rod 113 and the friction damping element 114 generates a damping force. The friction damping element 114 can increase the damping coefficient of the sleeve 112, thereby increasing the damping force between the friction rod 113 and the sleeve 112.

[0083] In one embodiment, a friction damping element 114 is disposed within a sleeve 112. The friction damping element 114 has through holes extending through its two end faces along a first direction, and a friction rod 113 is slidably inserted into the through holes. The friction damping element 114 has a generally annular structure, which is simple in structure and easy to manufacture.

[0084] For example, in some embodiments, the friction damper 114 is generally annular and the friction rod 113 is a circular rod.

[0085] In one embodiment, please refer to Figure 4 The sleeve 112 has a receiving cavity and a sliding channel 112a extending axially along the friction rod 113. The receiving cavity surrounds the outer periphery of the sliding channel 112a. The second end of the sleeve 112 has an insertion port communicating with the sliding channel 112a. The first end of the friction rod 113 is inserted into the sliding channel 112a through the insertion port. The friction damping element 114 is sleeved on the outside of the friction rod 113 and accommodated in the receiving cavity. The cavity wall restricts the movement of the friction damping element 114 along the axial direction of the friction rod 113.

[0086] In one embodiment, please refer to Figure 4 The first end of the sleeve 112 has a first connecting portion 111, and the receiving cavity is located at the second end of the sleeve 112. With this design, the length of the sleeve 112 in the first direction can be relatively short while satisfying the sliding stroke of the friction rod 113 in the first direction, so as to facilitate the assembly of the vibration damping device 100 in the limited installation space inside the housing.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] In some embodiments, the clothes container is generally cylindrical.

[0092] In some embodiments, the outer barrel is generally cylindrical.

[0093] 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.

[0094] 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.

[0095] 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 111 connects to the bottom of the outer tub, and a second connecting part 131 connects to the reinforcing seat 500. For example, the first direction can be consistent with the front-to-back direction. The reinforcing seat 500 can enhance the structural strength of the container, improve its rigidity, and reduce vibrations generated by the container.

[0096] In some embodiments, the sleeve 112, friction rod 113, and adapter 130 are all rigid structures. That is, the sleeve 112, friction rod 113, and adapter 130 do not deform significantly under the forces generated during the operation of the barrel assembly 200.

[0097] For example, the sleeve 112, friction rod 113 and adapter 130 can all be made of metal or steel with high rigidity.

[0098] The third vibration isolator 150, the second vibration isolator 140, and the first vibration isolator 120 can all be flexible structures. That is to say, the third vibration isolator 150, the second vibration isolator 140, and the first vibration isolator 120 can all deform under the force generated during the operation of the barrel assembly 200, thereby consuming vibration energy.

[0099] Both the third vibration isolator 150 and the first vibration isolator 120 can be made of nitrile rubber.

[0100] The second vibration isolator 140 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.

[0101] 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.
