[0050] In the garment processing device provided in this application embodiment, the distance from the first rotation axis to the axis of the second rod is not less than the distance from the first rotation axis to the axis of the first rod. This means that the lever arm of the force exerted by the second rod on the first rotation axis is not less than the lever arm of the force exerted by the first rod on the first rotation axis. During operation or washing, the drum assembly wobbles, meaning the vibration generated by the drum assembly is transmitted through the second rod to the vibration damping component, then through the vibration damping component to the first rod, and finally to the housing. The relatively long lever arm of the force exerted by the second rod on the first rotation axis allows the vibration damping component to move within a larger range, facilitating better absorption of the drum assembly's vibration energy, thus reducing the vibration energy transmitted from the drum assembly to the housing. Furthermore, the relatively short distance between the first rod and the first rotation axis helps reduce the swing space required for the first moving part in the swing plane, resulting in a more compact structure.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0079] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0080] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0081] This application provides a garment processing device 100. Please refer to Figures 1, 2 and 3. The garment processing device 100 includes a housing 1, a drum assembly 2 and a vibration damping device 300.

[0082] It should be noted that barrel assembly 2 can also be referred to as barrel assembly.

[0083] The bucket assembly 2 is housed inside the housing 1. The housing 1 provides storage space and protection for the bucket assembly 2, isolating it from the outside world and reducing the chance of dust and other impurities coming into contact with it. When the garment processing equipment 100 is subjected to impact, the housing 1 can also effectively withstand the external impact, reducing the chance of damage to the bucket assembly 2.

[0084] It is understood that the tub assembly 2 may include an inner tub and an outer tub, with the inner tub disposed inside the outer tub, and the space within the inner tub defining the garment handling chamber. The inner tub may be a perforated inner tub or a non-perforated inner tub. When the inner tub is a perforated inner tub, it relies on the outer tub to hold water; when the inner tub is a non-perforated inner tub, it relies on the inner tub itself to hold water. That is, the inner tub can hold both water and clothes, and during the washing process, water from the inner tub will not enter the outer tub. In some embodiments, the tub assembly 2 may only have an inner tub without an outer tub; in this case, the inner tub is a non-perforated inner tub.

[0085] It should be noted that the inner tub can also be called the inner cylinder, and the outer tub can also be called the outer cylinder.

[0086] In this embodiment, the bucket assembly 2, which includes an inner bucket and an outer bucket, is used as an example for explanation.

[0087] Understandably, when the clothing processing equipment 100 is in the washing or spin-drying state, the inner tub rotates, and the clothes inside the inner tub will shift during the rotation of the inner tub, causing the center of gravity of the inner tub to shift, thus causing the inner tub to rotate eccentrically, resulting in the outer tub vibrating and swaying. When the degree of eccentricity of the inner tub rotation increases, the amplitude of the outer tub will also increase, making the tub assembly 2 prone to hitting the box body 1, affecting the spin-drying process.

[0088] Please refer to Figure 2. The vibration damping device 300 connects the tub assembly 2 and the housing 1. The vibration damping device 300 is used to absorb the vibration energy of the tub assembly 2 during washing or spin-drying, reduce the vibration displacement of the tub assembly 2, and reduce the probability of the tub assembly 2 hitting the housing 1.

[0089] Please refer to Figure 1. The vibration damping device 300 includes a first rod 4, a second rod 5, and a vibration damping assembly 3. The vibration damping assembly 3 includes a first moving member 31 and a second moving member 32. The first moving member 31 and the second moving member 32 are rotatably connected and define a first rotation axis L2. The end of the first moving member 31 away from the first rotation axis L2 is directly or indirectly connected to the box 1 through the first rod 4. The end of the second moving member 32 away from the first rotation axis L2 is connected to the barrel assembly 2 through the second rod 5.

[0090] In other words, the vibration damping device 300 is directly or indirectly connected to the box 1 through the first rod 4, and connected to the barrel assembly 2 through the second rod 5.

[0091] It should be noted that a rotating connection can also be called a pivot connection.

[0092] It should be noted that the vibration damping device 300 is directly or indirectly connected to the housing 1 through the first rod 4. This means that the location of the first rod 4 is not limited. For example, it can be directly connected to the housing 1 as part of the hanger 6 described below, or it can be directly connected to the housing 1 by setting the first mounting base of the housing 1 described below, or it can be indirectly connected to the housing 1 by connecting to the hanger 6 described below, or it can be indirectly connected to the housing 1 by connecting to the workbench 9 described below, or it can be other connection methods, as long as the housing 1 can provide support for the first rod 4.

[0093] It should be noted that the first moving part 31 and the second moving part 32 are rotatably connected and define the first rotation axis L2, which means that at least one of the first moving part 31 and the second moving part 32 can rotate around the first rotation axis L2, thereby causing the first moving part 31 and the second moving part 32 to rotate relative to each other.

[0094] When the garment processing equipment 100 is in washing or spin-drying mode, the vibration of the drum assembly 2 is transmitted to the housing 1 via the second rod 5, the second moving part 32, the first moving part 31, and the first rod 4. The first moving part 31 and the second moving part 32 are rotatably connected, that is, the vibration of the drum assembly 2 is transmitted through the relative rotation of the first moving part 31 and the second moving part 32. This facilitates the adaptive movement of the first moving part 31 and the second moving part 32 as the vibration position of the drum assembly 2 changes, increasing the vibration damping reliability of the damping component 3. At the same time, it also facilitates the vibration buffering of the drum assembly 2 by appropriately increasing the resistance to the relative rotation between the first moving part 31 and the second moving part 32.

[0095] In some embodiments, the distance from the first rotation axis L2 to the axis of the second rod 5 is not less than the distance from the first rotation axis L2 to the axis of the first rod 4.

[0096] It should be noted that the distance from the first rotation axis L2 to the axis of the second rod 5 refers to the distance from the center of the rotational connection between the first moving member 31 and the second moving member 32 to the center of the second through hole 3231 mentioned below, as shown in Figure 7a, when projected onto the plane perpendicular to the axis L1 of the barrel assembly 2; the distance from the first rotation axis L2 to the axis of the first rod 4 refers to the distance from the center of the rotational connection between the first moving member 31 and the second moving member 32 to the center of the first through hole 3131 mentioned below, as shown in Figure 7b, when projected onto the plane perpendicular to the axis L1 of the barrel assembly 2, and a≥b.

[0097] The distance from the first rotation axis L2 to the axis of the second rod 5 is not less than the distance from the first rotation axis L2 to the axis of the first rod 4, meaning that the lever arm of the force exerted by the second rod 5 on the first rotation axis L2 is not less than the lever arm of the force exerted by the first rod 4 on the first rotation axis L2. During operation or washing, the tub assembly 2 wobbles, meaning the vibration generated by the tub assembly 2 is transmitted through the second rod 5 to the vibration damping assembly 3, then through the vibration damping assembly 3 to the first rod 4, and finally to the housing 1. The relatively long lever arm of the force exerted by the second rod 5 on the first rotation axis L2 allows the vibration damping assembly 3 to move within a larger range, facilitating better absorption of the vibration energy of the tub assembly 2, thus reducing the vibration energy transmitted from the tub assembly 2 to the housing 1. Furthermore, the relatively short distance between the first rod 4 and the first rotation axis L2 helps reduce the swing space required for the first moving part 31 in the swing plane, resulting in a more compact structure.

[0098] In some embodiments, the distance from the first rotation axis L2 to the axis of the second rod 5 is 1 to 1.3 times the distance from the first rotation axis L2 to the axis of the first rod 4, i.e., 1 ≤ a / b ≤ 1.3. By controlling the relationship between the lever arm of the force exerted by the second rod 5 on the first rotation axis L2 and the lever arm of the force exerted by the first rod 4 on the first rotation axis L2, it is helpful to achieve a reasonable arrangement of the first rod 4, the first moving part 31, the second moving part 32, and the second rod 5 within the limited space between the box 1 and the barrel assembly 2, thereby achieving both a compact structure and a good vibration reduction effect.

[0099] In some embodiments, referring to Figures 1 and 8, the first rotation axis L2 is substantially parallel to the axis L1 of the barrel assembly 2.

[0100] It should be noted that the basic parallelism refers to the fact that the angle between the first rotation axis L2 and the axis L1 of the barrel assembly 2 can be 0° or close to 0°, that is, a certain amount of processing and assembly error is allowed.

[0101] Understandably, during washing or spin-drying, the tub assembly 2 vibrates in both the horizontal and vertical directions, with the horizontal vibration being dominant. The vertical vibration displacement of the tub assembly 2 is small and less likely to cause impact with the tub, while the horizontal vibration displacement is large and easily exceeds the horizontal gap between the casing 1 and the tub assembly 2, potentially causing impact with the casing 1. Therefore, it is necessary to effectively suppress the horizontal vibration of the tub assembly 2. In related technologies, the rotation axes of the first and second moving parts of the vibration damping components are approximately parallel to the horizontal direction, meaning that the first and second moving parts mainly oscillate along the vertical plane. The damping force on the vibration is mainly decomposed into a force along the vertical direction, with a small component along the horizontal direction. Therefore, it cannot effectively absorb the horizontal vibration of the tub assembly, resulting in limited vibration damping effect.

[0102] It is understood that the horizontal direction refers to the direction parallel to the horizontal plane after the garment processing equipment 100 is placed on a horizontal ground, such as the left-right direction, the front-back direction, and other horizontal directions that intersect with the left-right and front-back directions.

[0103] For example, the height direction is the direction shown in Figures 1 and 11, which includes both the top-down direction and the bottom-up direction.

[0104] In this embodiment, when the tub assembly 2 vibrates and wobbles, the first moving part 31 and the second moving part 32 of the vibration damping component 3 can rotate relative to each other around their connection point and define the first rotation axis L2. Since the first rotation axis L2 is basically parallel to the height direction, that is, the first moving part 31 and the second moving part 32 rotate relative to each other in a roughly horizontal direction. The resistance to the relative rotation between the first moving part 31 and the second moving part 32 is roughly in the horizontal direction, which is used to reduce the horizontal vibration of the tub assembly 2, effectively suppress the horizontal vibration of the tub assembly 2, reduce the vibration displacement of the tub assembly 2, reduce the probability of the tub assembly 2 hitting the box 1, and thus reduce the noise of the clothing processing equipment 100.

[0105] In some other embodiments, the included angle between the first rotation axis L2 and the axis L1 of the barrel assembly 2 does not exceed 15°.

[0106] Please refer to Figures 1 and 8. The axis L1 of the bucket assembly 2 and the first rotation axis L2 are two spatially skew lines. In this embodiment, the included angle refers to the angle formed between the first rotation axis L2 and the bucket assembly 2 in the same plane after the first rotation axis L2 is translated to intersect with the axis L1 of the bucket assembly 2.

[0107] In this embodiment, the first rotation axis L2 is inclined relative to the axis L1 of the barrel assembly 2, and the inclination angle is small, which helps to improve the vibration reduction effect on the circumferential vibration of the barrel assembly 2 and reduce the probability of jamming at the rotational connection of the first moving part 31 and the second moving part 32.

[0108] In some embodiments, the included angle between the first moving member 31 and the second moving member 32 does not exceed 180°. That is, the included angle between the line connecting the centers of the first end and the second end of the first moving member 31 and the line connecting the centers of the first end and the second end of the second moving member 32 does not exceed 180°.

[0109] It is understood that the angle not exceeding 180° means that, before or during the relative rotation of the first moving member 31 and the second moving member 32, taking one of the first moving member 31 and the second moving member 32 as a reference, the angle between the line connecting the centers of the first and second ends of the first moving member 31 and the line connecting the centers of the first and second ends of the second moving member 32 along the same direction does not exceed 180°. For example, referring to Figure 7, taking the first moving member 31 as a reference, the angle between the line A1 connecting the centers of the first and second ends of the first moving member 31 and the line A2 connecting the centers of the first and second ends of the second moving member 32 along the clockwise direction shown in Figure 7 never exceeds 180°.

[0110] In this embodiment, the included angle between the first moving part 31 and the second moving part 32 can limit the relative position change of the first moving part 31 and the second moving part 32 to a reasonable range, so that the first moving part 31 and the second moving part 32 can adapt to the vibration position change of the barrel assembly 2, thereby increasing the vibration damping reliability of the vibration damping assembly 3.

[0111] In some examples, please refer to Figure 7, when the barrel assembly 2 is in a stationary state, the included angle between the first moving part 31 and the second moving part 32, that is, the included angle α between the line A1 connecting the centers of the first end and the second end of the first moving part 31 and the line A2 connecting the centers of the first end and the second end of the second moving part 32, is not less than 50° and not more than 120°, that is, 50°≤α≤120°, for example, 50°, 55°, 60°, 63°, 69°, 72°, 75°, 86°, 90°, 95°, 100°, 110°, 120°, etc.

[0112] In this embodiment, when the bucket assembly 2 is in a stationary state, the included angle between the first moving part 31 and the second moving part 32 is within a suitable range. On the one hand, this facilitates the relative rotation of the first moving part 31 and the second moving part 32 under the vibration of the bucket assembly 2. On the other hand, it also ensures that the second moving part 32 has a sufficient range of rotation when rotating relative to the first moving part 31, thereby increasing the vibration damping reliability of the vibration damping assembly 3.

[0113] In some embodiments, the first moving member 31 and the second moving member 32 surround an annular cavity, and the vibration damping assembly 3 includes a damping member 33 disposed in the annular cavity. The damping member 33 is used to provide damping force during the relative rotation of the first moving member 31 and the second moving member 32.

[0114] The annular cavity is the space between the first annular portion 3111 and the second annular portion 3211. The damping member 33 is disposed in the annular cavity, that is, the damping member 33 is disposed between the first annular portion 3111 and the second annular portion 3211. The annular cavity can provide installation space for the damping member 33 and can also limit the position of the damping member 33.

[0115] It is understandable that the form in which the damping element 33 provides damping force is not limited. For example, it can generate frictional damping by rubbing against the first moving element 31 and the second moving element 32 respectively. It can also generate elastic damping by using the elastic deformation of the damping element 33 to compress the first moving element 31 and the second moving element 32. Alternatively, the damping element 33 can generate elastic deformation while rubbing against the first moving element 31 and the second moving element 32.

[0116] In this embodiment, when the bucket assembly 2 vibrates and wobbles, the first moving part 31 and the second moving part 32 rotate relative to each other. The damping part 33 provides damping force during the relative rotation of the first moving part 31 and the second moving part 32 to suppress the vibration of the bucket assembly 2. That is, the damping force reduces the vibration of the bucket assembly 2, so as to achieve vibration buffering of the bucket assembly 2 and thereby reduce the noise of the whole machine.

[0117] The material of the damping element 33 is not limited. For example, the damping element 33 can be made of polyurethane foam with high wear resistance or soft rubber with high wear resistance. It has a high coefficient of friction on its surface and can deform to cooperate with the first moving element 31 and the second moving element 32. Of course, the damping element 33 can also be made of semi-metallic friction materials, etc., and there are no restrictions here.

[0118] It is understandable that the formation of the annular cavity is not limited. For example, the first moving member 31 includes a first main body portion 311, the first main body portion 311 includes a first annular portion 3111, the second moving member 32 includes a second main body portion 321, the second main body portion 321 includes a second annular portion 3211, the first annular portion 3111 and the second annular portion 3211 are nested together, and the first annular portion 3111 and the second annular portion 3211 are radially spaced to define the annular cavity. In this case, the annular cavity is the space between the first annular portion 3111 and the second annular portion 3211.

[0119] The first annular portion 3111 and the second annular portion 3211 are nested together, meaning that either the first annular portion 3111 is embedded within the second annular portion 3211, or the second annular portion 3211 is embedded within the first annular portion 3111.

[0120] Please refer to Figure 8. In some embodiments, the first annular portion 3111 is sleeved on the outer periphery of the second annular portion 3211.

[0121] In some embodiments, referring to FIG6, the first annular portion 3111 and the second annular portion 3211 are nested together to define the first rotation axis L2.

[0122] The nested arrangement of the first annular portion 3111 and the second annular portion 3211 defines the first rotation axis L2, that is, the first annular portion 3111 and the second annular portion 3211 are coaxially arranged, which helps to ensure the relative motion stability between the first annular portion 3111 and the second annular portion 3211, and helps to reduce additional vibration and wear caused by eccentricity.

[0123] In some embodiments, as shown in Figures 6 and 8, the first main body 311 includes a first end plate 3112 connected to the first annular portion 3111, and the second main body 321 includes a second end plate 3212 connected to the second annular portion 3211. The first annular portion 3111 and the second annular portion 3211 are located between the first end plate 3112 and the second end plate 3212.

[0124] In this embodiment, the first end plate 3112 and the second end plate 3212 can provide support for the first annular portion 3111 and the second annular portion 3211, and the first annular portion 3111 and the second annular portion 3211 are defined between the first end plate 3112 and the second end plate 3212. This can increase the docking stability of the first annular portion 3111 and the second annular portion 3211, reduce the probability of loosening at the docking point of the first annular portion 3111 and the second annular portion 3211, and at the same time, reduce the probability of the damping member 33 coming out of the annular cavity, and isolate the damping member 33 from other components outside the vibration damping assembly 3, so that the installation stability of the vibration damping assembly 3 is good.

[0125] In some embodiments, the first end plate 3112 and the second end plate 3212 are arranged in parallel. This can further increase the smoothness of the first moving member 31 and the second moving member 32 when they rotate relative to each other.

[0126] Please refer to Figures 6 and 8. The vibration damping assembly 3 also includes a first fastening assembly 34, which includes a connector 342 that passes through a first end plate 3112 and a second end plate 3212.

[0127] Specifically, the connector 342 can connect the first end plate 3112 and the second end plate 3212, thereby fixing the first annular portion 3111 and the second annular portion 3211 along the direction of the first rotation axis L2, reducing the probability of the first annular portion 3111 dislodging from the second annular portion 3211 or the second annular portion 3211 dislodging from the first annular portion 3111. At the same time, it can also reduce the probability of the damping member 33 dislodging from the annular cavity, increase the installation stability of the vibration damping assembly 3, and also increase the stability of the first moving member 31 and the second moving member 32 when they rotate relative to each other.

[0128] The specific structure of the connector 342 is not limited, as long as it can connect the first moving part 31 and the second moving part 32 without affecting the relative rotation of the first moving part 31 and the second moving part 32. For example, the connector 342 can be a rivet.

[0129] It is understood that the first fastening assembly 34 may also include a gasket 341. Referring to Figures 6 and 8, when the first annular portion 3111 surrounds the outer periphery of the second annular portion 3211, the gasket 341 is disposed on the first end plate 3112, and the connector 342 passes through the gasket 341, the first end plate 3112, and the second end plate 3212 in sequence. The gasket 341 can protect the first end plate 3112 and reduce the probability of damage to the first end plate 3112.

[0130] When the second annular portion 3211 surrounds the outer periphery of the first annular portion 3111, the gasket 341 is disposed on the second end plate 3212, and the connector 342 passes through the gasket 341, the second end plate 3212, and the first end plate 3112 in sequence.

[0131] In some embodiments, the second annular portion 3211 surrounds the outer periphery of the first annular portion 3111, and the inner surface of the second annular portion 3211 is provided with a rib 3111a protruding toward the first annular portion 3111. The sidewall of the damping member 33 has a notch 33a, and the rib 3111a is inserted into the notch 33a.

[0132] Alternatively, please refer to Figures 9 and 10. The first annular portion 3111 surrounds the outer periphery of the second annular portion 3211. The inner surface of the first annular portion 3111 has a rib 3111a protruding toward the second annular portion 3211. The sidewall of the damping member 33 has a notch 33a, and the rib 3111a is inserted into the notch 33a.

[0133] In this embodiment, the cooperation between the rib 3111a and the notch 33a notches not only enables the installation and positioning of the damping component 33, but also reduces the probability of the damping component 33 rotating in the annular cavity when the first moving component 31 and the second moving component 32 do not rotate relative to each other after the damping component 33 is installed, thereby increasing the installation stability of the vibration damping assembly 3.

[0134] It should be noted that the protruding rib 3111a can also be called a stop rib.

[0135] It should be noted that in the embodiment where the second annular portion 3211 surrounds the outer periphery of the first annular portion 3111, when only the first moving member 31 rotates around the connection point between the two, causing the first moving member 31 and the second moving member 32 to rotate relative to each other, the second moving member 32 does not rotate around the connection point. In this case, the damping member 33 also does not rotate within the annular cavity. When the second moving member 32 rotates around the connection point, regardless of whether the first moving member 31 rotates around the connection point, the damping member 33 can rotate within the annular cavity under the influence of the second moving member 32.

[0136] Similarly, in the embodiment where the first annular portion 3111 surrounds the outer periphery of the second annular portion 3211, when only the second moving member 32 rotates around the connection point between the two, causing the first moving member 31 and the second moving member 32 to rotate relative to each other, the first moving member 31 does not rotate around the connection point. In this case, the damping member 33 also does not rotate within the annular cavity. When the first moving member 31 rotates around the connection point, regardless of whether the second moving member 32 rotates around the connection point, the damping member 33 can rotate within the annular cavity under the influence of the first moving member 31.

[0137] In some embodiments, referring to FIG5, the first moving member 31 includes a first connecting portion 313 connected to the first main body portion 311. The first connecting portion 313 is provided with a first through hole 3131, and the first rod 4 passes through the first through hole 3131. The first moving member 31 is at least circumferentially rotatable around the first rod 4. That is, the first rod 4 is adapted to pass through the first through hole 3131.

[0138] That is, the first rod 4 is movably disposed in the first through hole 3131, thereby realizing the connection between the first rod 4 and the first moving part 31.

[0139] The first moving part 31 can rotate at least around the circumference of the first rod 4, including at least two cases:

[0140] The first type: The first moving part 31 is able to rotate around the circumference of the first rod 4. Thus, the first moving part 31 has at least one rotational degree of freedom.

[0141] The second type: the first moving member 31 is capable of rotating around the circumference of the first rod 4 and sliding along the extension direction of the first rod 4. Thus, the first moving member 31 has at least one rotational degree of freedom and one sliding degree of freedom.

[0142] It should be noted that the structure of the first rod 4 is not limited, but refers to the structure that enables the first moving part 31 to rotate around the first rod 4 in the circumference. The first rod 4 can be a slender rod or a structure such as a pin.

[0143] For example, as shown in FIG5, the sidewall structure of the first through hole 3131 is further provided with an opening 3132, which penetrates the end faces of the opposite ends of the first through hole 3131 in the axial direction.

[0144] It should be noted that the opening 3132 penetrates the axially opposite end faces of the first through hole 3131, meaning that the hole wall of the first through hole 3131 is disconnected in the circumferential direction, and the first through hole 3131 and the opening 3132 have a certain elastic deformation capability.

[0145] In this embodiment, during the process of the first rod 4 passing through the first through hole 3131, or when the first moving member 31 moves relative to the first rod 4, the first through hole 3131 and the opening 3132 can undergo elastic deformation to adapt to the size of the first through hole 3131 required when the first rod 4 is installed or when the first moving member 31 moves relative to the first rod 4.

[0146] It should be noted that the opening 3132 can also be referred to as the first through groove 31334.

[0147] In some embodiments, please continue to refer to Figure 5, the second moving member 32 is provided with a second through hole 3231 at one end near the second rod 5, the second rod 5 passes through the second through hole 3231, and the second moving member 32 can at least rotate around the second rod 5 in the circumferential direction.

[0148] The second rod 5 is movably disposed in the second through hole 3231, thereby realizing the connection between the second rod 5 and the second moving part 32.

[0149] The second moving part 32 can rotate at least around the circumference of the second rod 5, including at least two cases:

[0150] The first type: The second moving member 32 is capable of rotating around the circumference of the second rod 5. Thus, the second moving member 32 has at least one rotational degree of freedom.

[0151] The second type: the second moving member 32 is capable of rotating around the circumference of the second rod 5 and sliding along the extension direction of the second rod 5. Thus, the second moving member 32 has at least one rotational degree of freedom and one sliding degree of freedom.

[0152] It should be noted that the structure of the second rod 5 is not limited, but refers to the structure that enables the second moving part 32 to rotate around the second rod 5 in the circumference. The second rod 5 can be a slender rod or a structure such as a pin.

[0153] For example, the sidewall structure of the second through hole 3231 is also provided with a second through groove 31334, which penetrates the end faces of the two opposite ends of the second through hole 3231 in the axial direction.

[0154] It should be noted that the second through groove 31334 penetrates the axially opposite end faces of the second through hole 3231, meaning that the hole wall of the second through hole 3231 is disconnected in the circumferential direction, and the second through hole 3231 and the second through groove 31334 have a certain elastic deformation capability.

[0155] Thus, during the process of the second rod 5 passing through the second through hole 3231, or when the second moving member 32 moves relative to the second rod 5, the second through hole 3231 and the second through groove 31334 can undergo elastic deformation to adapt to the size of the second through hole 3231 required when the second rod 5 is installed or when the second moving member 32 moves relative to the second rod 5.

[0156] In some embodiments, as shown in FIG6, the sidewall of the second rod 5 is provided with a first deformation groove 5a. The first deformation groove 5a allows the second rod 5 to contract at least partially inward so that the second rod 5 passes through the second through hole 3231, and the second moving member 32 can rotate around the circumference of the second rod 5. In this embodiment, the second through groove 31334 may not be provided, and the contraction capability of the first deformation groove 5a can be used to allow the second rod 5 to pass through the second through hole 3231.

[0157] In some embodiments, please refer to FIG6, the garment handling device 100 includes a bushing 7 disposed in a second through hole 3231, and a second rod 5 passing through and in contact with the bushing 7.

[0158] In this embodiment, the bushing 7 serves two purposes: firstly, it facilitates the insertion of the second rod 5 into the second through hole 3231; secondly, when the second moving part 32 rotates around the second rod 5, the inner wall of the second through hole 3231 does not directly contact or rub against the second rod 5, thus reducing the probability of damage to the vibration damping component 3 and further reducing the generation of impact noise.

[0159] It should be noted that bushing 7 can also be called pin bushing.

[0160] In some embodiments, please refer to FIG6, the garment processing device 100 further includes a damping sleeve 8, a bushing 7 passing through the damping sleeve 8, and the outer periphery of the damping sleeve 8 contacting the wall of the second through hole 3231.

[0161] It is understandable that the bushing 7 can be made of metal. The bushing 7 is set in the second through hole 3231, and the second rod 5 passes through the second through hole 3231. When the second moving part 32 rotates around the second rod 5, the friction with the bushing 7 will also damage the vibration damping component 3.

[0162] In this embodiment, the damping sleeve 8 can isolate the second through hole 3231 from the bushing 7, reducing the contact wear between the inner wall of the second through hole 3231 and the bushing 7. In addition, the damping sleeve 8 can also play a buffering and damping role, further reducing the probability of noise generation.

[0163] The damping sleeve 8 can be made of plastic or rubber. When the bushing 7 and the second rod 5 are inserted into the second through hole 3231, the damping sleeve 8 can undergo appropriate deformation, and the damping sleeve 8 is in close contact with the inner wall of the second through hole 3231, the bushing 7 is in close contact with the damping sleeve 8, and the second rod 5 is in close contact with the bushing 7, thereby achieving a stable fit between the second rod 5 and the second through hole 3231.

[0164] It should be noted that the vibration damping sleeve 8 can also be called a sleeve.

[0165] In some embodiments, referring to FIG6, the sidewall of the bushing 7 is provided with a second deformation groove 7a, which penetrates the opposite ends of the sidewall of the bushing 7 along the axial direction, so that the bushing 7 can generate radial elastic deformation.

[0166] In this embodiment, the second deformation groove 7a is provided so that the bushing 7 can undergo radial elastic deformation to press the damping sleeve 8 tightly. The second rod 5 then contracts inward under the action of the first deformation groove 5a to fit with the bushing 7. In this way, when the second moving part 32 adapts to the vibration displacement of the barrel assembly 2 by rotation, it can generate almost no impact noise or generate very little impact noise.

[0167] Understandably, the placement of the first rod 4 is not limited.

[0168] For example, in some embodiments, please refer to Figures 1 to 4, the garment processing device 100 includes a plurality of hanging rods 6, one end of each hanging rod 6 is connected to the tub assembly 2 and the other end is connected to the housing 1, and the tub assembly 2 is suspended on the housing 1 by the plurality of hanging rods 6.

[0169] Specifically, the top end of the hanging rod 6 is fixed to the housing 1, and the bottom end of the hanging rod 6 is fixed to the bucket assembly 2. There can be four hanging rods 6. The top ends of the four hanging rods 6 correspond to the four corners of the top of the housing 1, and the bottom ends of the four hanging rods 6 are fixed to the side walls of the bucket assembly 2 corresponding to the four corners of the housing 1. In this way, each hanging rod 6 can evenly distribute the weight of the bucket assembly 2, increasing the installation stability of the clothing processing equipment 100.

[0170] Please refer to Figure 1. The first rod 4 is part of the lifting rod 6.

[0171] In this embodiment, the first moving component 31 is connected to the hanging rod 6 via the first rod 4. There is sufficient installation space between the bucket assembly 2 and the hanging rod 6 to arrange the vibration damping component 3. The hanging rod 6 has sufficient structural strength to provide sufficient motion support for the vibration damping component 3. The end of the vibration damping component 3 connected to the hanging rod 6 will not detach from the hanging rod 6, increasing the installation stability of the vibration damping component 3. In addition, the other end of the vibration damping component 3 is not directly connected to the housing 1. The vibration energy of the bucket assembly 2 is transmitted to the housing 1 via the vibration damping component 3 and the hanging rod 6, which can reduce the vibration energy received by the housing 1 and increase the operational stability of the clothing processing equipment 100.

[0172] Of course, in other embodiments, the first rod 4 may also be connected to the boom 6. The boom 6 can provide support for the first rod 4, thereby providing sufficient support for the first moving member 31.

[0173] It is understandable that a vibration damping structure can also be provided on the hanger rod 6 to buffer the vibration of the tub assembly 2. For example, referring to Figure 1, the garment processing equipment 100 includes a damping cylinder 63, a base support 64 disposed at the bottom end of the hanger rod 6, and a vibration damping spring 62. The vibration damping spring 62 passes through the hanger rod 6 and is sandwiched between the damping cylinder 63 and the base support 64. A connecting groove 2a is formed on the outer peripheral wall of the bottom end of the tub assembly 2, and the connecting groove 2a is sleeved on the damping cylinder 63. Specifically, the damping cylinder 63 is sleeved on the hanger rod 6, and the vibration damping spring 62 is a compression spring. One end of the vibration damping spring 62 abuts against the bottom end of the damping cylinder 63, and the other end abuts against the base support 64. Thus, when the tub assembly 2 vibrates during washing or spin-drying, the vibration damping spring 62 slides up and down along the hanger rod 6 to absorb the longitudinal vibration energy of the tub assembly 2, thereby reducing the vibration noise of the housing 1 and increasing the operational stability of the garment processing equipment 100.

[0174] It should be noted that the damping spring 62 can also be referred to as a spring assembly. The base 64 can also be referred to as a spring seat.

[0175] The number of vibration damping devices 300 is unlimited. For example, please refer to Figure 2. There are four vibration damping devices 300, that is, there are four first rods 4 and four vibration damping components 3. One end of the four vibration damping components 3 is connected to the tub assembly 2, and the other end is connected to the hanging rod 6. Thus, the vibration damping components 3 can buffer the vibration of the tub assembly 2 evenly and fully from different directions, increase the vibration damping effect, and improve the operational safety of the clothing processing equipment 100.

[0176] For example, the four corner plates 11 of the housing 1 are respectively provided with vibration damping devices 300.

[0177] In some other embodiments, the number of vibration damping components 300 can be two. Among the four corner plates 11 of the housing 1, the two corner plates 11 located on the diagonal are respectively provided with vibration damping devices 300.

[0178] In other embodiments, please refer to FIG11, the garment processing device 100 includes a workbench 9, which is disposed at the top of the housing 1. One end of the first rod 4 is connected to the workbench 9, and the other end extends downward from the workbench 9 to form a suspended free end, or extends downward and is connected to the lower part or bottom plate of the housing 1.

[0179] It is understandable that the workbench 9 is located on the top side of the housing 1. The workbench 9 has a clothing inlet that communicates with the clothing processing chamber. In other words, the clothes to be washed can be put into the clothing processing chamber from the top side through the clothing inlet, and the washed clothes can also be taken out of the clothing processing chamber through the clothing inlet.

[0180] In this embodiment, the end of the vibration damping component 3 away from the first rod 4 is connected to the bucket component 2, and the other end is connected to the workbench 9 through the first rod 4. The bucket component 2 and the workbench 9 together provide installation support for the vibration damping device 300, thereby increasing the installation stability and motion stability of the vibration damping device 300. Furthermore, the vibration damping device 300 is not directly connected to the housing 1. The vibration energy of the bucket component 2 is transmitted to the housing 1 through the vibration damping device 300 and the workbench 9. The workbench 9 can share some of the vibration energy of the housing 1, thereby reducing the vibration noise of the housing 1 and increasing the operational stability of the clothing processing equipment 100.

[0181] In addition, the first rod 4 extends downward from the worktable 9, and the axis of the first rod 4 is along the height direction, which helps to reduce the motion resistance of the first moving part 31.

[0182] In some embodiments, the garment processing device 100 includes a first mounting base disposed on the housing 1, and at least one end of the first rod 4 is disposed on the first mounting base.

[0183] In this embodiment, one end of the vibration damping component 3 is connected to the barrel component 2, and the other end is connected to the first mounting base of the box 1 through the first rod 4, so that the vibration damping device 300 is connected to the barrel component 2 and the box 1 respectively. The barrel component 2 and the box 1 together provide support for the vibration damping device 300. In this way, the vibration damping device 300 has sufficient installation space and movement space, which is convenient for buffering the vibration of the barrel component 2.

[0184] For example, the first moving part 31 can be a plastic part, and the material can be wear-resistant materials such as nylon and polyoxymethylene. It is lightweight and easy to mass-produce.

[0185] For example, the second moving part 32 can be a plastic part, and the material can be wear-resistant materials such as nylon and polyoxymethylene. It is lightweight and easy to mass-produce.

[0186] Referring to Figures 15 and 16, in some embodiments, in the embodiment where the first rod 4 is part of the lifting rod 6, the first main body 311 is pivotally connected to the second main body 321, and the first connecting part 313 includes a body part 3133 having a first through hole 3131. The first elastic part 3514 and the second elastic part 3514 located on both sides of the center line connecting the first main body 311 and the first through hole 3131 of the body part 3133 are both capable of elastic deformation.

[0187] In this embodiment, the second main body 321 of the second moving member 32 is pivotally connected to the first main body 311 of the first moving member 31, so that the first moving member 31 and the second moving member 32 can rotate relative to each other within a preset angle to generate a damping force. The first connecting part 313 of the first moving member 31 is sleeved on the outer periphery of the hanging rod 6 through the first through hole 3131, and the hanging rod 6 is used to connect to the housing 1. In this way, when the garment processing equipment 100 is in the dehydration start-up stage, the drum assembly 2 swings significantly under the action of eccentric centrifugal force, generating vibration. The vibration damping device 300 absorbs and releases a portion of the vibration energy by generating a damping force through the relative rotation of the first moving member 31 and the second moving member 32 within the preset angle, thereby reducing the lateral vibration displacement of the drum assembly 2. Among them, the first connecting part 313 of the first moving member 31 is sleeved on the outer periphery of the hanging rod 6, and the first connecting part 313 is easily deformed by the force applied by the hanging rod 6.

[0188] Therefore, in this embodiment, the first connecting portion 313 includes a body portion 3133 with a first through hole 3131. The first connecting portion 313 is sleeved on the outer periphery of the suspension rod 6 through the first through hole 3131. The first elastic portion 3514 and the second elastic portion 3514 on both sides of the center line connecting the first main body portion 311 and the first through hole 3131 of the body portion 3133 can both undergo elastic deformation. The connection point between the suspension rod 6 and the first connecting portion 313, i.e., the position on both sides of the center line of the body portion 3133, is the stress area. The stress area is provided with the first elastic portion 3514 and the second elastic portion 3514 on both sides of the center line. When vibration occurs, the suspension rod 6 will repeatedly act on this stress area. Since the first elastic portion 3514 and the second elastic portion 3514 in this stress area can both undergo elastic deformation, they will not deform or even be damaged due to stress concentration. In this way, the first connecting portion 313 is not prone to fatigue failure, thus improving the service life of the vibration damping device 300.

[0189] According to the vibration damping device 300 of this application embodiment, the second main body 321 of the second moving member 32 is pivotally connected to the first main body 311 of the first moving member 31, so that the second moving member 32 and the first moving member 31 rotate relative to each other within a preset angle to generate damping force. This allows the device to absorb and release some vibration energy when the drum assembly 2 starts dehydrating, reducing the vibration displacement of the drum assembly 2 and preventing the drum assembly 2 from impacting the housing 1 with excessive amplitude. In addition, the first connecting part 313 includes a body part 3133 with a first through hole 3131. The first connecting part 313 is sleeved on the outer periphery of the hanger 6 through the first through hole 3131. The first elastic part 3514 and the second elastic part 3514 of the body part 3133, located on both sides of the center line connecting the first main body part 311 and the first through hole 3131, can both undergo elastic deformation and will not deform or even be damaged due to stress concentration. This reduces the possibility of fatigue failure of the first connecting part 313 and improves the service life of the vibration damping device 300.

[0190] In some embodiments, the body portion 3133 includes an inner peripheral structure 31331 and an outer peripheral structure 31332. The inner peripheral structure 31331 forms a first through hole 3131, and the outer peripheral structure 31332 is spaced apart on the outer peripheral side of the inner peripheral structure 31331. A plurality of reinforcing ribs 31333 are connected between the inner peripheral structure 31331 and the outer peripheral structure 31332, and a through groove 31334 is formed between two adjacent reinforcing ribs 31333.

[0191] Referring to Figures 18 and 19, if the wall thickness of the first through hole 3131 is too thick, elastic deformation is not easily achieved, and the lifting rod 6 is prone to jamming when moving within the first through hole 3131. If the wall thickness of the first through hole 3131 is too thin, the strength is insufficient, and the lifting rod 6 is prone to breaking the first through hole 3131 when moving within it. Therefore, a reinforcing rib 31333 is connected between the inner peripheral structure 31331 and the outer peripheral structure 31332 of the first connecting part 313. A through groove 31334 is formed between two adjacent reinforcing ribs 31333. The through groove 31334 can reduce the wall thickness of the first through hole 3131, increase the deformability of the periphery of the first through hole 3131, prevent the hanger 6 from being stuck when moving in the first through hole 3131, enhance the fatigue resistance of the periphery of the first through hole 3131 under long-term deformation, and the reinforcing rib 31333 can increase the structural strength of the periphery of the first through hole 3131, prevent the first through hole 3131 from being pulled apart by the hanger 6, and further extend the service life of the vibration damping device 300.

[0192] In some embodiments, a plurality of reinforcing ribs 31333 and a plurality of through grooves 31334 are located on both sides of the central line, and the first elastic portion 3514 and the second elastic portion 3514 both include through grooves 31334.

[0193] Referring again to Figure 19, the first connecting part 313 is sleeved on the outer periphery of the hanger 6 through the first through hole 3131. The connection between the hanger 6 and the first connecting part 313, i.e., the position on both sides of the center line of the main body 3133, is the stress area. The stress area is provided with a first elastic part 3514 and a second elastic part 3514 located on both sides of the center line. When vibration occurs, the hanger 6 will repeatedly act on the stress area. Multiple reinforcing ribs 31333 and multiple through grooves 31334 are located on both sides of the center line. Both the first elastic part 3514 and the second elastic part 3514 include through grooves 31334, which can make the first elastic part 3514 and the second elastic part 3514 on both sides of the center line elastically deform. This can increase the structural strength and deformability of the periphery of the first through hole 3131, thereby enhancing the fatigue resistance of the periphery of the first through hole 3131 under long-term deformation, preventing deformation or even damage due to stress concentration, and further improving the service life of the vibration damping device 300.

[0194] In some embodiments, a transition portion 3135 is connected between the first main body portion 311 and the outer peripheral structure 31332, and a portion of the outer peripheral structure 31332 corresponding to the through groove 31334 is indirectly connected to the transition portion 3135.

[0195] As shown in Figure 19, a transition portion 3135 connects the first main body 311 and the outer peripheral structure 31332. A part of the structure of the outer peripheral structure 31332 corresponding to the through groove 31334 is directly connected to the transition portion 3135 so that the first main body 311 and the outer peripheral structure 31332 meet the basic connection strength requirements. The other part of the structure is indirectly connected to the transition portion 3135, which can increase the elastic deformation capacity of the stress area on both sides of the center line and further enhance the fatigue resistance of the long-term deformation of the periphery of the first through hole 3131.

[0196] In some embodiments, the outer peripheral structure 31332, the plurality of reinforcing ribs 31333 and the plurality of through grooves 31334 are symmetrically arranged with respect to the center line.

[0197] Referring again to Figure 19, in one example, the outer contour of the body portion 3133 along the cross-section perpendicular to the central axis of the first through hole 3131 includes a semicircular arc, first straight line segments 3136a tangent to both ends of the semicircular arc, and a second straight line segment 3136a connecting the two first straight line segments 3136a. The length of the first straight line segment 3136a is greater than the radius of the first through hole 3131, and the first through hole 3131 is concentrically arranged with the semicircular arc. Compared with the technical solution where the body portion 3133 is a complete ring, this body portion 3133 occupies less space and is more compatible with the smaller garment processing device 100. The connection points of the semicircular arc, the first straight line segment 3136a, and the second straight line segment 3136a are respectively connected by rounded corners to prevent the edges from scratching the operator. In addition, the outer peripheral structure 31332, multiple reinforcing ribs 31333 and multiple through slots 31334 are symmetrically arranged relative to the center line, which can make the stress area on both sides of the center line uniform, that is, the part of the vibration damping device 300 connected to the hanger 6 is uniformly stressed, further enhancing the fatigue resistance of the periphery of the first through hole 3131 to long-term deformation.

[0198] In some embodiments, the plurality of through slots 31334 include a third through slot 31334a and a fourth through slot 31334b. The distance between the third through slot 31334a and the center line is greater than the distance between the fourth through slot 31334b and the center line, and the length of the third through slot 31334a along the circumferential direction is greater than the length of the fourth through slot 31334b along the circumferential direction. The transition portion 3135 is provided with the third through slot 31334a and the fourth through slot 31334b on both sides of the center line, wherein the portion of the outer peripheral structure 31332 corresponding to the third through slot 31334a is indirectly connected to the transition portion 3135.

[0199] As shown in Figure 19, the main body 3133 includes five reinforcing ribs 31333 spaced apart along its outer periphery, two third through slots 31334a and two fourth through slots 31334b. The distance between the third through slot 31334a and the center line refers to the distance between any point in the third through slot 31334a and the center line. The distance between the fourth through slot 31334b and the center line refers to the distance between any point in the fourth through slot 31334b and the center line. The distance between the third through slot 31334a and the center line is greater than the distance between the fourth through slot 31334b and the center line, that is, the length of the third through slot 31334a along the circumferential direction is greater than the length of the fourth through slot 31334b along the circumferential direction.

[0200] As shown in Figure 18, the transition section 3135, the outer peripheral structure 31332, multiple reinforcing ribs 31333, and multiple through slots 31334 are symmetrically arranged with respect to the center line. The transition section 3135 has a third through slot 31334a and a fourth through slot 31334b on each side of the center line. The portion of the outer peripheral structure 31332 corresponding to the fourth through slot 31334b is directly connected to the transition section 3135, while the portion of the outer peripheral structure 31332 corresponding to the third through slot 31334a is indirectly connected to the transition section 3135. This further increases the deformability of the portion of the main body 3133 located around the first through hole 3131, preventing the boom 6 from getting stuck when moving within the first through hole 3131 and enhancing the fatigue resistance of the periphery of the first through hole 3131 during long-term deformation.

[0201] In addition, grooves are provided on both sides of the transition portion 3135 along its own thickness direction, which can reduce the weight of the first moving part 31, while improving the structural strength and deformation resistance of the transition portion 3135.

[0202] In some embodiments, the body portion 3133 includes a first surface and a second surface that are opposite to each other along its own thickness direction, and the first through hole 3131 includes a first hole 3131a and a second hole 3131b that are sequentially arranged along the thickness direction of the body portion 3133. The first hole 3131a is arranged to gradually narrow along the axial direction from the first surface to the second surface, and the second hole 3131b is arranged to gradually narrow along the axial direction from the second surface to the first surface.

[0203] As shown in Figure 20, the first through hole 3131 includes a first hole 3131a and a second hole 3131b arranged sequentially along the thickness direction of the body portion 3133. Both the first hole 3131a and the second hole 3131b are conical holes, and the openings 3132 of the conical holes are in opposite directions, which facilitates the large-scale swing of the lifting rod 6 within the first through hole 3131 without jamming. The diameter of the hole at the connection between the first hole 3131a and the second hole 3131b is the smallest, and this diameter can be larger than the diameter of the lifting rod 6. The first through hole 3131 and the lifting rod 6 are clearance-fitted, allowing the first connecting part 313 to be slidably fitted onto the lifting rod 6. In this way, when the barrel assembly 2 vibrates in the vertical direction, the vibration damping device 300 can be in a horizontal or nearly horizontal state through the sliding of the first connecting part 313 on the lifting rod 6, so that the vibration damping device 30010 can generate a horizontal damping force, which is beneficial to increasing the horizontal damping effect and preventing the barrel assembly 2 from having an excessive lateral vibration displacement that could impact the housing 1.

[0204] In some embodiments, the walls of the first hole 3131a and the second hole 3131b are respectively provided with oil reservoirs. The oil reservoirs can hold lubricating oil or grease, which can reduce the friction of the hanger 6 during the swinging process, reduce the wear at the first through hole 3131, and further extend the service life of the vibration damping device 300.

[0205] In some embodiments, the first through hole 3131 is provided with an opening 3132 along the circumferential direction, and the opening 3132 is set at a preset angle between the center line and the center line along the circumferential direction; the first connecting part 313 also includes an anti-detachment part 3134 connected to the body part 3133, the anti-detachment part 3134 is disposed on the side of the body part 3133 away from the first main body part 311 and connected to the opening 3132, and the anti-detachment part 3134 forms a guide channel S communicating with the first through hole 3131.

[0206] As shown in Figures 18 and 19, the boom 6 passes through the first through hole 3131 of the body portion 3133 of the first connecting part 313. The first through hole 3131 has an opening 3132 along the circumferential direction, which can increase the deformation at the first through hole 3131 and prevent the boom 6 from getting stuck when moving in the first through hole 3131. In addition, the first connecting part 313 also includes an anti-detachment part 3134 connected to the body portion 3133. The anti-detachment part 3134 is connected to the opening 3132 to prevent the first through hole 3131 from deforming too much when the barrel assembly 2 vibrates too much, causing the boom 6 to damage the first through hole 3131.

[0207] In some embodiments, the preset angle between the centerline of the opening 3132 along the circumferential direction and the center line is 0°.

[0208] As shown in Figure 19, the main body 3133 is symmetrically arranged with respect to the center line. The preset angle between the center line of the opening 3132 along the circumferential direction and the center line is 0°. That is, the opening 3132 of the main body 3133 is symmetrically arranged with respect to the center line, which can make the force on the periphery of the first through hole 3131 of the main body 3133 uniform and prevent deformation or even damage due to stress concentration.

[0209] In some embodiments, the preset angle between the centerline of the opening 3132 along the circumferential direction and the center line is greater than -45° and less than 45°. The body part 3133 can be asymmetrically arranged relative to the center line. In this case, the preset angle between the centerline of the opening 3132 along the circumferential direction and the center line is greater than -45° and less than 45°. In this way, when the vibration of the barrel assembly 2 is too large, the lifting rod 6 can enter the anti-detachment part 3134 through the first through hole 3131 via the opening 3132, avoiding the lifting rod 6 from damaging the first through hole 3131 due to excessive deformation of the first through hole 3131. The preset angle of greater than -45° and less than 45° also ensures that there is a sufficient area for deformation in the circumferential direction along the counterclockwise or clockwise direction from the opening 3132, and deformation or even damage will not occur due to stress concentration.

[0210] In some embodiments, the anti-detachment part 3134 includes an extension 3134a and a bend 3134b spaced apart to form a guide channel S. The extension 3134a extends outward from one end of the opening 3132 in a direction parallel to the center line, and the bend 3134b is formed by bending around the extension 3134a from the other end of the opening 3132. The guide channel S includes a first channel S1, a second channel S2 and a third channel S3 arranged sequentially and formed in a U-shape. The first channel S1 is connected to the first through hole 3131, and the third channel S3 is gradually narrowed in a direction away from the second channel S2.

[0211] As shown in Figure 8, the guide channel S formed between the protruding portion 3134a and the bent portion 3134b of the anti-detachment part 3134 is a labyrinthine channel. This channel ensures sufficient deformation of the main body 3133 while preventing the lifting rod 6 from detaching from the main body 3133 of the first connecting portion 313. Specifically, the first channel S1 of the guide channel S is connected to the first through hole 3131 and is parallel to the center line; the second channel S2 is perpendicular to the center line; and the third channel S3 gradually narrows away from the second channel S2. The widths of both the first and second channels S1 and S2 are smaller than the diameter of the lifting rod 6, and the width at the end of the third channel S3 is smaller than the diameter of the lifting rod 6. Thus, when the boom 6 tends to slide from the opening 3132 side of the first through hole 3131 towards the guide channel S, since the widths of the first channel S1 and the second channel S2 are both smaller than the diameter of the boom 6, the boom 6 is not likely to slide into the first channel S1 and the second channel S2. Even if the body part 3133 is subjected to a large force, resulting in a large deformation at the first through hole 3131, and the boom 6 slides into the first channel S1 and the second channel S2, since the third channel S3 is gradually narrowed in the direction away from the second channel S2, the end of the third channel S3 can also restrict the boom 6 from falling out of the guide channel S, enhance the fatigue resistance of the anti-detachment part 3134 under long-term deformation, and improve the connection reliability between the first moving part 31 and the boom 6.

[0212] In some embodiments, the bent portion 3134b includes a first rib portion 3134c and a second rib portion 3134d disposed on the outer periphery of the first rib portion 3134c, wherein the first rib portion 3134c is bent around the protrusion portion 3134a, and the thickness of the second rib portion 3134d is less than the thickness of the first rib portion 3134c.

[0213] As shown in Figures 15 and 19, the first rib 3134c of the bent portion 3134b is formed by bending around the protruding portion 3134a. The thickness of the second rib 3134d is less than the thickness of the first rib 3134c. The second rib 3134d can make the overall thickness of the bent portion 3134b thinner, which not only meets the structural strength requirements of the anti-detachment portion 3134, but also improves the deformation resistance of the anti-detachment portion 3134, and further enhances the fatigue resistance of the first connecting portion 313 under long-term deformation.

[0214] In some embodiments, the outer periphery of the first main body 311 is provided with a first limiting platform 314 and a second limiting platform 315 respectively connected to the two sides of the transition portion 3135. The first limiting platform 314 is located on one side of the center line, and the second limiting platform 315 is located on the other side of the center line. The second moving member 32 also includes a second connecting portion 323 connected to the second main body 321. A third limiting platform 3213 extending in the circumferential direction is provided on the side of the second main body 321 away from the second connecting portion 323. A fourth limiting platform 3214 extending in a circumferential direction is provided on the side facing the second connecting part 323. When the first moving member 31 rotates relative to the second moving member 32 in the first direction by a first angle γ1, the first limiting platform 314 abuts against the third limiting platform 3213. When the first moving member 31 rotates relative to the second moving member 32 in the second direction by a second angle γ2, the second limiting platform 315 abuts against the fourth limiting platform 3214. The first direction is opposite to the second direction, and the sum of the first angle γ1 and the second angle γ2 is less than 180°.

[0215] As shown in Figures 17 and 18, the second connecting part 323 of the second moving member 32 can be used to connect with the bucket assembly 2. The first connecting part 313 of the first moving member 31 is sleeved on the outer periphery of the lifting rod 6 through the first through hole 3131. The lifting rod 6 is used to connect with the box body 1. The outer periphery of the first main body part 311 of the first moving member 31 is provided with a first limiting platform 314 and a second limiting platform 315. The outer periphery of the second main body part 321 of the second moving member 32 is provided with a third limiting platform 3213 and a fourth limiting platform 3214. Assuming that the second moving member 32 is stationary, when the first moving member 31 rotates counterclockwise by a first angle γ1 relative to the second moving member 32 to the limit position, the first limiting platform 314 abuts against the third limiting platform 3213; when the first moving member 31 rotates clockwise by a second angle γ2 relative to the second moving member 32 to the limit position, the first limiting platform 314 abuts against the fourth limiting platform 3214.

[0216] The second moving part 32 and the first moving part 31 are rotatable relative to each other within a preset angle, which is the sum of the first angle γ1 and the second angle γ2. Optionally, the first angle γ1 = 50° to 90° and the second angle γ2 = 40° to 90°. In one example, the first angle γ1 = 80° and the second angle γ2 = 45°. The magnitudes of the first angle γ1 and the second angle γ2 are determined according to the spatial layout of the vibration damping device 300. γ1 + γ2 < 180° to prevent the second moving part 32 and the first moving part 31 from failing to return to their initial positions due to excessive rotation angle during rotation, thereby losing their damping and vibration reduction function.

[0217] In some embodiments, a fifth limiting platform 316 connected to the second limiting platform 315 is also provided on the outer periphery of the first main body 311. The outer diameter of the fifth limiting platform 316 is smaller than the inner diameter of the fourth limiting platform 3214. A first anti-fool angle θ1 is formed between the first limiting platform 314 and the fifth limiting platform 316 on one side of the transition portion 3135. A second anti-fool angle θ2 is formed between the third limiting platform 3213 and the fourth limiting platform 3214, other than the rotation angle of the first moving member 31 relative to the second moving member 32. The first anti-fool angle θ1 is greater than the second anti-fool angle θ2.

[0218] As shown in Figure 17, the first anti-mistake angle θ1 of the first moving member 31 is the angle formed between the first limiting platform 314 and the fifth limiting platform 316 on one side of the transition portion 3135. The second anti-mistake angle θ2 of the second moving member 32 is the angle formed between the third limiting platform 3213 and the fourth limiting platform 3214, other than the rotation angle of the first moving member 31 relative to the second moving member 32. θ1 > θ2, which ensures that the position of the second moving member 32 and the first moving member 31 after assembly meets the spatial layout requirements and vibration reduction requirements of the garment processing equipment 100. For example, in Figures 12 and 17, the first moving members 31 of the four vibration damping devices 300 are all located to the right of the second moving member 32.

[0219] In an embodiment with a damping member 33, the damping member 33 is an annular structure. The damping member 33 has an opening 3132 along its circumference. The first annular portion 3111 has a receiving cavity 3113. The sidewall of the receiving cavity 3113 is provided with a protruding rib 3111a. The damping member 33 is accommodated in the receiving cavity 3113, and the notch 33a is snapped into the protruding rib 3111a. The second main body portion 321 is provided with a second annular portion 3211 that cooperates with the damping member 33. The second main body portion 321 is pivotally connected to the first main body portion 311 through the second annular portion 3211.

[0220] It should be noted that the second annular portion 3211 can also be referred to as a protruding post.

[0221] As shown in Figures 16 and 17, the first limiting platform 314 of the first main body 311 is located on the outer periphery of the receiving cavity 3113, which can prevent the deformation of the receiving cavity 3113 from affecting the magnitude of the damping force and ensure the consistency of damping. The notch 33a of the damping member 33 is engaged with the protruding rib 3111a provided on the side wall of the receiving cavity 3113, which can prevent the damping member 33 from rotating with the rotation of the first main body 311 and increase the friction between the damping member 33 and the first main body 311. At the same time, the second main body 321 is provided with a second annular part 3211 that cooperates with the damping member 33. The outer peripheral surface of the second annular part 3211 generates a damping force between the inner wall of the damping member 33. This damping force is used to absorb and release vibration energy and reduce the lateral vibration displacement of the barrel assembly 2.

[0222] In some embodiments, the ribs 3111a are symmetrically arranged with respect to the center line. When the body portion 3133 of the first connecting portion 313 is symmetrically arranged with respect to the center line, the portions of the body portion 3133 located on both sides of the center line are the stress-bearing areas. The symmetrical arrangement of the ribs 3111a with respect to the center line can ensure that the damping member 33 and the first connecting portion 313 have the same vibration direction, avoiding relative rotation between the damping member 33 and the ribs 3111a, which could cause the damping member 33 to be damaged due to stress concentration, and further extending the service life of the vibration damping device 300.

[0223] Referring to FIG22, in some embodiments, the vibration damping component 3 includes a locking member 35, and at least one opening 3132 is formed on the circumferential edge of the first through hole 3131. The locking member 35 is at least partially disposed outside the opening 3132. In a first state, the locking member 35 at least partially closes the opening 3132; in a second state, the locking member 35 opens the opening 3132.

[0224] In related technologies, a first rod is installed on the housing, and this first rod is connected to the vibration damping component. During actual assembly, the first rod must first pass through the first through-hole of the vibration damping component before being connected to the housing. This means the vibration damping component must be manufactured together with the first rod. If any component of the vibration damping component is damaged during handling, production line testing, or home use, the entire vibration damping component must be scrapped, requiring disassembly and replacement of the entire housing assembly. This is time-consuming, labor-intensive, and has high repair costs.

[0225] Therefore, in this embodiment, a first through hole 3131 is formed on the vibration damping component 3, and at least one opening 3132 is formed on the circumferential edge of the first through hole 3131. The number of openings 3132 can be one, two, or more. The openings 3132 can increase the elastic deformation of the first through hole 3131, preventing the first rod 4 from being jammed by the first through hole 3131 during vibration. The first rod 4 can be assembled with the housing 1 first, and then the first rod 4 can be installed into the first through hole 3131 through the opening 3132 to connect the vibration damping component 3 to the housing 1. In this way, the vibration damping component 3 can be manufactured separately from the first rod 4, making the assembly method more flexible, convenient, and quick. Even if a component of the vibration damping component 3 is damaged, it is only necessary to remove the first rod 4 from the first through hole 3131 along the opening 3132 and then replace the damaged component. It is not necessary to disassemble and replace the entire tank assembly 2, saving time and effort and reducing maintenance costs.

[0226] In this embodiment, the first rod 4 can also be referred to as a connecting rod.

[0227] In one example, one end of the first rod 4 is connected to the housing 1, and the other end of the first rod 4 is connected to the barrel assembly 2. The first rod 4 is installed into the first through hole 3131 through the opening 3132 of the vibration damping assembly 3. In this embodiment, one end of the first rod 4 is connected to the housing 1, and the other end is connected to the barrel assembly 2. One end of the vibration damping assembly 3 is connected to the first rod 4, and the other end is fixed to the barrel assembly 2. This achieves both a stable connection of the vibration damping assembly 3 and a vibration damping effect. In this embodiment, the first rod 4 is part of the suspension rod 6.

[0228] In another example, one end of the first rod 4 is connected to the housing 1, and the other end of the first rod 4 is a free end. The outer diameter of the free end is larger than the inner diameter of the first through hole 3131. The first rod 4 is installed into the first through hole 3131 through the opening 3132 of the vibration damping component 3. The barrel assembly 2 is connected to the vibration damping component 3 by fasteners to connect the vibration damping component 3 between the housing 1 and the barrel assembly 2. In this embodiment, the other end of the first rod 4 can be connected to the housing 1 along with one end of the first rod 4. In this case, both ends of the first rod 4 are connected to the housing 1, and the middle part of the first rod 4 passes through the first through hole 3131 of the vibration damping component 3 to achieve installation.

[0229] In addition, to reduce the possibility of the vibration damping component 3 coming loose from the first through hole 3131 along the opening 3132 during the vibration of the barrel assembly 2, the vibration damping component 3 also includes a locking member 35. The locking member 35 is disposed on the outside of the opening 3132 and is used to open or close the opening 3132. In the first state, the locking member 35 opens the opening 3132, and the first rod 4 is installed into the first through hole 3131 through the opening 3132 to complete the assembly of the vibration damping component 3 and the first rod 4, or the first rod 4 is taken out from the first through hole 3131 along the opening 3132 to separate the first rod 4 from the vibration damping component 3; in the second state, the locking member 35 closes the opening 3132 to reduce the possibility of the first rod 4 coming loose from the first through hole 3131 along the opening 3132 during use.

[0230] According to the embodiments of this application, the vibration damping component 3 can cooperate with the first rod 4 to be connected between the housing 1 and the tub assembly 2 of the clothing processing equipment 100. At least a portion of the first rod 4 is disposed on the housing 1. By forming a first through hole 3131 on the vibration damping component 3, and forming at least one opening 3132 on the circumferential edge of the first through hole 3131, the first rod 4 can be installed into the first through hole 3131 through the opening 3132 after the first rod 4 is assembled with the housing 1 and / or the tub assembly 2. Thus, the vibration damping component 3 and the first rod 4 can be manufactured separately, and the assembly is convenient and quick with low maintenance costs. In addition, the vibration damping component 3 also includes a locking member 35 disposed outside the opening 3132. When the locking member 35 opens the opening 3132, the first rod 4 can be installed into the first through hole 3131 through the opening 3132, or the first rod 4 can be taken out from the first through hole 3131 through the opening 3132. When the locking member 35 closes the opening 3132, it can reduce the possibility of the first rod 4 coming out of the first through hole 3131 during use and improve the reliability of the vibration damping component 3.

[0231] In some embodiments, a first through hole 3131 and a locking member 35 are disposed on a first connecting portion 313. Referring to FIG23, in this embodiment of the application, a first rod 4 is installed into the first through hole 3131 through an opening 3132 so that the first rod 4 is connected to the first connecting portion 313, thereby connecting the first connecting portion 313 to the housing 1.

[0232] In some embodiments, the first connecting portion 313 is further provided with a guide opening 3136, which extends from the opening 3132 in a direction away from the first through hole 3131, and at least a portion of the locking member 35 is provided on the outside of the guide opening 3136.

[0233] Referring to Figure 3, the guide opening 3136 of the first connecting portion 313 extends from the opening 3132 in a direction away from the first through hole 3131. The guide opening 3136 can increase the path of the first rod 4 vibrating back and forth within the first through hole 3131 of the first connecting portion 313, buffer the impact force received by the first rod 4 during vibration, and prevent the periphery of the first through hole 3131 from being damaged due to stress concentration when the impact force is too large. At the same time, it is used to guide the first rod 4 to be installed into the first through hole 3131 through the opening 3132. At least a portion of the locking member 35 is provided on the outside of the guide opening 3136 to close the guide opening 3136 and reduce the possibility of the first rod 4 coming out of the guide opening 3136.

[0234] In some embodiments, the guide opening 3136 includes a straight segment 3136a and an open segment 3136b, with the straight segment 3136a disposed between the opening 3132 and the open segment 3136b; the first connecting portion 313 includes a first rib 31361 and a second rib 31362 forming the guide opening 3136, with the straight segments 3136a of the first rib 31361 and the straight segments 3136a of the second rib 31362 arranged in parallel, and the open segments 3136b of the first rib 31361 and the open segments 3136b of the second rib 31362 gradually expanding in a direction away from the straight segment 3136a.

[0235] As shown in Figure 3, the straight segments 3136a of the first rib 31361 and the second rib 31362 are arranged in parallel, mainly to buffer the impact force on the first rod 4 during vibration, and to prevent the periphery of the first through hole 3131 from being damaged due to stress concentration when the impact force is too large. The open segments 3136b of the first rib 31361 and the second rib 31362 are gradually widened in the direction away from the straight segment 3136a, which is used to guide the first rod 4 to be installed into the first through hole 3131 through the opening 3132, thereby improving the assembly efficiency of the first rod 4 and the vibration damping component 3.

[0236] In some embodiments, the locking member 35 includes a first locking portion 351 and a second locking portion 352. The first locking portion 351 is disposed on the open section 3136b of the first rib 31361. The first locking portion 351 and the second locking portion 352 are located on both sides of the opening 3132 along the extension direction of the guide opening 3136. The first locking portion 351 and the second locking portion 352 are connected to at least partially close the opening 3132.

[0237] Optionally, the locking component 35 is a plastic part, and its material can be ABS or POM. Optionally, the locking component 35 and the first connecting part 313 are an integral structural component, and the two are formed by injection molding to improve the connection strength between the locking component 35 and the first connecting part 313. Optionally, the locking component 35 and the first connecting part 313 are separately provided, and the two are connected into one unit by means of bonding, threaded connection, etc. Optionally, the first locking part 351 and the second locking part 352 of the locking component 35 are detachably connected, which can realize multiple assembly and disassembly, saving time and effort, and further reducing maintenance costs.

[0238] In some embodiments, the first rib 31361 of the guide opening 3136 is connected to the end of the outer peripheral structure 31332. The "end of the outer peripheral structure 31332" refers to the fact that the outer peripheral structure 31332 of the first connecting part 313 is disconnected by the guide opening 3136 into a non-closed structure, so that the first rib 31361 forming the guide opening 3136 is connected to the end of the outer peripheral structure 31332, while the second rib 31362 is disconnected from the end of the outer peripheral structure 31332. The first rib 31361 can increase the structural strength of the periphery of the first through hole 3131 and prevent the first through hole 3131 from being pulled apart by the first rod 4.

[0239] In some embodiments, the outer peripheral structure 31332 includes recesses 3137 and protrusions 3138 that are alternately arranged in the circumferential direction, and a reinforcing rib 31333 is connected between the inner peripheral structure 31331 and the protrusions 3138.

[0240] As shown in Figure 24, the outer peripheral surface of the first connecting portion 313 includes alternating recesses 3137 and protrusions 3138 arranged circumferentially. Multiple reinforcing ribs 31333 are provided between the periphery of the first through hole 3131 and the protrusions 3138. The open section 3136b of the first rib 31361 is connected to the protrusion 3138, while the open section 3136b of the second rib 31362 is disconnected from the protrusion 3138. Through grooves 31334 are formed between the first rib 31361 and the reinforcing ribs 31333, and between two adjacent reinforcing ribs 31333. A blind groove is formed between the second rib 31362 and the reinforcing ribs 31333. The blind groove can improve the connection strength between the first connecting portion 313 and the first main body portion 311. The through groove 31334 can reduce the wall thickness of the first through hole 3131, increase the deformability of the periphery of the first through hole 3131, prevent the first rod 4 from getting stuck when moving in the first through hole 3131, and also facilitate the installation of the first rod 4 into the first through hole 3131 along the deformed guide opening 3136. In addition, the alternating concave portions 3137 and convex portions 3138 on the outer peripheral surface of the first connecting portion 313 have a compact structure, which can enhance the fatigue resistance of the first through hole 3131 under long-term deformation and extend the service life of the vibration damping assembly 3.

[0241] In some embodiments, the first locking part 351 includes a strip 3511 disposed on one side of the guide opening 3136 and a head 3512 connected to the strip 3511, and the second locking part 352 is connected to the head 3512.

[0242] As shown in Figures 23 and 24, when the locking member 35 closes the opening 3132, one end of the strip 3511 is connected to the open section 3136b of the first rib 31361, and the other end of the strip 3511 is detachably connected to the second locking part 352 on the outside of the open section 3136b of the second rib 31362 via the head 3512. Optionally, the head 3512 is a pin, and the second locking part 352 includes a mounting hole and a guide groove that communicates with the mounting hole and is gradually widened. The mounting hole is adapted to the pin, and the guide groove is used to guide the pin into the mounting hole, improving the assembly efficiency of the locking member 35. Optionally, the central axis of the mounting hole is approximately parallel to the central axis of the first through hole 3131. The mounting hole is adapted to the pin, and the opening 3132 can be closed by the friction between the two. Without external force, the pin is difficult to dislodge from the mounting hole, improving the reliability of the locking member 35.

[0243] In some embodiments, a sixth limiting platform 317 is provided on the outer periphery of the first connecting portion 313, and the sixth limiting platform 317 is located outside the second rib 31362. A second locking portion 352 is provided on the sixth limiting platform 317, and the second locking portion 352 is a groove and / or blind hole that cooperates with the head 3512.

[0244] As shown in Figure 3, the first rib 31361 of the guide opening 3136 is connected to the protrusion 3138, and the second rib 31362 is disconnected from the protrusion 3138. The side of the second rib 31362 facing the guide opening 3136 is the inner side, and the side away from the guide opening 3136 is the outer side. The sixth limiting platform 317 is located outside the second rib 31362. The strip 3511 is connected in an arc shape between the first rib 31361 and the sixth limiting platform 317, which can improve the structural strength of the first connecting part 313. At the same time, the second locking part 352 is provided on the sixth limiting platform 317. The second locking part 352 includes a mounting hole and a guide groove that communicates with the mounting hole and is gradually widened, which can prevent the locking member 35 from pulling off the second rib 31362 and improve the connection strength of the locking member 35.

[0245] Specifically, the first locking part 351 includes a strip 3511 disposed on one side of the first guide opening 3136 and a head 3512 connected to the strip 3511, and the second locking part 352 is connected to the head 3512.

[0246] The first locking part 351 also includes a wing part 3513 and / or an elastic part 3514 connected to the rear end of the head 3512 and connected to the head 3512. The cross-sectional area of ​​the rear end of the head 3512 is larger than the cross-sectional area of ​​the front end of the head 3512. The wing part 3513 adjusts the outer diameter of the head 3512 through the elastic part 3514. The second locking part 352 is a blind hole adapted to the head 3512.

[0247] As shown in Figure 26, in one example, the head 3512 is arranged in an arrow-shaped structure, and the wing 3513 is arranged in an arc-shaped thin-walled structure. The cross-sectional area of ​​the rear end of the head 3512 is larger than the cross-sectional area of ​​the front end of the head 3512. Here, "front end" refers to the end of the head 3512 away from the wing 3513, and "rear end" is arranged opposite to "front end". "Cross-section" refers to the plane that is cut off by the front end or rear end of the head 3512 by a plane perpendicular to the axis of the head 3512. Two symmetrically arranged elastic portions 3514 are provided between the rear end of the head 3512 and the wing portion 3513. The elastic portions 3514 have a thin-walled structure. The operator can manually or with a tool clamp the two ends of the wing portion 3513 to shorten the distance between the two elastic portions 3514, thereby reducing the outer diameter of the head 3512. This makes it easier to insert the head 3512 into the blind hole of the second locking portion 352. Loosening the two ends of the wing portion 3513 allows the head 3512 to be engaged in the blind hole, so that the locking member 35 can close the opening 3132. When it is necessary to open the opening 3132, the operator can manually or with a tool clamp the two ends of the wing portion 3513 again to reduce the outer diameter of the head 3512, and then remove the head 3512 from the blind hole.

[0248] In another example, the first locking part 351 includes a head 3512 and wings 3513 located at the rear end of the head 3512. There can be two wings 3513, symmetrically arranged and spaced apart. An operator manually or using a tool presses the first locking part 351 toward the second locking part 352. As the head 3512 gradually enters the blind hole of the second locking part 352, the outer diameter of the head 3512 gradually decreases, facilitating insertion of the head 3512 into the blind hole of the second locking part 352. This allows the locking member 35 to close the opening 3132. The two ends of the wings 3513 partially cover the blind hole. Alternatively, the wings 3513 can be connected to the rear end of the head 3512, allowing the head 3512 to enter the blind hole by clamping the two ends of the wings 3513.

[0249] In another embodiment, the first locking part 351 includes a head 3512 and an elastic part 3514 connected to the rear end of the head 3512. The operator can clamp and squeeze the elastic part 3514 to gradually reduce the outer diameter of the head 3512, thereby making it easier to insert the head 3512 into the blind hole of the second locking part 352, so as to achieve the effect of locking member 35 closing the opening 3132.

[0250] Optionally, the blind hole of the second locking part 352 is provided on the sixth limiting stage 317, and the central axis of the blind hole is perpendicular to the central axis of the first through hole 3131. In this way, part of the head 3512 of the first locking part 351 is inserted into the blind hole, making the locking member 35 structure compact and reducing the space occupied.
