Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and more particularly to a clothing processing device. Background Technology

[0002] Taking a pulsator-type garment processing equipment as an example, with the external dimensions of the cabinet remaining unchanged, as the washing volume increases, the gap between the drum assembly and the cabinet becomes smaller and smaller. During the washing or spin-drying process, the drum assembly will vibrate and sway, and is prone to impacting the cabinet, affecting the safety of the garment processing equipment. Summary of the Invention

[0003] In view of this, embodiments of this application aim to provide a garment processing device that can reduce the vibration energy transmitted from the drum assembly to the box.

[0004] This application provides a garment processing device, including:

[0005] Box;

[0006] A barrel assembly is disposed within the box body;

[0007] A vibration damping device connects the bucket assembly and the box body. The vibration damping device includes a first rod, a second rod, and a vibration damping component. The vibration damping component includes a first moving part and a second moving part. The first moving part and the second moving part are rotatably connected and define a first rotation axis. The end of the first moving part away from the first rotation axis is directly or indirectly connected to the box body through the first rod. The end of the second moving part away from the first rotation axis is connected to the bucket assembly through the second rod.

[0008] Wherein, 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.

[0009] In some embodiments, the distance from the first rotation axis to the axis of the second rod is 1 to 1.3 times the distance from the first rotation axis to the axis of the first rod.

[0010] In some implementations, the first rotation axis is substantially parallel to the axis of the barrel assembly.

[0011] In some implementations, the angle between the first rotation axis and the axis of the barrel assembly does not exceed 15°.

[0012] In some implementations, the included angle between the first moving member and the second moving member does not exceed 180°.

[0013] In some embodiments, the first moving member and the second moving member enclose an annular cavity, and the vibration damping assembly includes a damping member disposed in the annular cavity for providing damping force during relative rotation of the first moving member and the second moving member.

[0014] In some embodiments, the first moving member includes a first annular portion, the second moving member includes a second annular portion, the first annular portion and the second annular portion are nested together and define the first rotation axis, and the first annular portion and the second annular portion are radially spaced to define the annular cavity.

[0015] In some implementations, the first moving member is provided with a first through hole at one end near the first rod, the first rod passes through the first through hole, and the first moving member can at least rotate circumferentially around the first rod;

[0016] And / or, the second moving member is provided with a second through hole at one end near the second rod, the second rod passes through the second through hole, and the second moving member can at least rotate circumferentially around the second rod.

[0017] In some embodiments, the sidewall structure of the first through hole is further provided with a first through groove, the first through groove penetrating the end faces of the opposite ends of the first through hole in the axial direction; and / or, the sidewall structure of the second through hole is further provided with a second through groove, the second through groove penetrating the end faces of the opposite ends of the second through hole in the axial direction.

[0018] In some embodiments, the garment handling equipment includes a plurality of hanging rods, one end of each hanging rod being connected to the tub assembly and the other end being connected to the housing, the tub assembly being suspended from the housing by the plurality of hanging rods, the first rod being part of the hanging rod, or the first rod being connected to the hanging rod;

[0019] Alternatively, the garment processing equipment includes a workbench, which is located at the top of the box, with one end of the first rod connected to the workbench and the other end extending downward from the workbench;

[0020] Alternatively, the garment processing device may include a mounting base disposed on the housing, with at least one end of the first rod disposed on the mounting base.

[0021] 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.

[0038] 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.

[0039] This application provides a garment processing device 100. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The garment processing equipment 100 includes a box 1, a drum assembly 2, and a vibration damping device 300.

[0040] 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.

[0041] 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.

[0042] In this embodiment, the bucket assembly 2, which includes an inner bucket and an outer bucket, is used as an example for explanation.

[0043] 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.

[0044] Please see 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.

[0045] Please see Figure 1 The vibration damping device 300 includes a first rod 4, a second rod 5, and a vibration damping component 3. The vibration damping component 3 includes a first moving part 31 and a second moving part 32. The first moving part 31 and the second moving part 32 are rotatably connected and define a first rotation axis L2. The end of the first moving part 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 part 32 away from the first rotation axis L2 is connected to the barrel assembly 2 through the second rod 5.

[0046] 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.

[0047] 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 by the mounting base of the housing 1 described below, or it can be indirectly connected to the housing 1 by the hanger 6 described below, or it can be indirectly connected to the housing 1 by 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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, as projected onto the plane perpendicular to the axis L1 of the barrel assembly 2, to the center of the second through hole 323a mentioned below. Figure 7 The distance shown in 'a'; 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 313a mentioned below, as projected onto the plane perpendicular to the axis L1 of the barrel assembly 2. Figure 7 The distance shown in b is a, and a ≥ b.

[0052] 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.

[0053] 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.

[0054] In some embodiments, please refer to Figure 1 and Figure 8 The first rotation axis L2 is basically parallel to the axis L1 of the barrel assembly 2.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] For example, the height direction is Figure 1 and Figure 11 The directions shown include both top-down and bottom-up directions.

[0059] 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.

[0060] 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°.

[0061] Please see Figure 1 and Figure 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.

[0062] 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.

[0063] 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°.

[0064] It is understood that the included 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 included 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, please refer to... Figure 7 Taking the first moving member 31 as a reference, the line A1 connecting the centers of the first end and the second end of the first moving member 31 and the line A2 connecting the centers of the first end and the second end of the second moving member 32 are along... Figure 7 The angle between the clockwise directions shown always does not exceed 180°.

[0065] 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.

[0066] For 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.

[0067] 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.

[0068] 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.

[0069] The annular cavity is the space between the first annular portion 311 and the second annular portion 321. The damping member is disposed in the annular cavity, that is, the damping member 33 is disposed between the first annular portion 311 and the second annular portion 321. The annular cavity can provide installation space for the damping member 33 and can also limit the position of the damping member 33.

[0070] 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 can generate elastic deformation while rubbing against the first moving element 31 and the second moving element 32.

[0071] 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.

[0072] 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.

[0073] It is understandable that the formation of the annular cavity is not limited. For example, the first moving member 31 includes a first annular portion 311, and the second moving member 32 includes a second annular portion 321. The first annular portion 311 and the second annular portion 321 are nested together, and the first annular portion 311 and the second annular portion 321 are arranged radially spaced to define the annular cavity. In this case, the annular cavity is the space between the first annular portion 311 and the second annular portion 321.

[0074] The first annular portion 311 and the second annular portion 321 are nested together, meaning that either the first annular portion 311 is embedded within the second annular portion 321, or the second annular portion 321 is embedded within the first annular portion 311.

[0075] Please see Figure 8 In some embodiments, the first annular portion 311 is sleeved on the outer periphery of the second annular portion 321.

[0076] In some embodiments, please refer to Figure 6 The first annular portion 311 and the second annular portion 321 are nested together to define the first rotation axis L2.

[0077] The nested arrangement of the first annular portion 311 and the second annular portion 321 defines the first rotation axis L2, that is, the first annular portion 311 and the second annular portion 321 are coaxially arranged, which helps to ensure the relative motion stability between the first annular portion 311 and the second annular portion 321 and helps to reduce additional vibration and wear caused by eccentricity.

[0078] In some embodiments, such as Figure 6 and Figure 8 As shown, the first moving member 31 includes a first end plate 312 connected to the first annular portion 311, and the second moving member 32 includes a second end plate 322 connected to the second annular portion 321. The first annular portion 311 and the second annular portion 321 are located between the first end plate 312 and the second end plate 322.

[0079] In this embodiment, the first end plate 312 and the second end plate 322 can provide support for the first annular portion 311 and the second annular portion 321, and the first annular portion 311 and the second annular portion 321 are defined between the first end plate 312 and the second end plate 322. This can increase the docking stability of the first annular portion 311 and the second annular portion 321, reduce the probability of loosening at the docking point of the first annular portion 311 and the second annular portion 321, 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.

[0080] In some embodiments, the first end plate 312 and the second end plate 322 are arranged in parallel. This further increases the smoothness of the first moving member 31 and the second moving member 32 when they rotate relative to each other.

[0081] Please see Figure 6 and Figure 8 The vibration damping component 3 also includes a connector 35, which passes through the first end plate 312 and the second end plate 322.

[0082] Specifically, the connector 35 can connect the first end plate 312 and the second end plate 322, thereby fixing the first annular portion 311 and the second annular portion 321 along the direction of the first rotation axis L2, reducing the probability of the first annular portion 311 dislodging from the second annular portion 321 or the second annular portion 321 dislodging from the first annular portion 311. 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.

[0083] The specific structure of the connector 35 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 35 can be a rivet.

[0084] It is understood that the garment handling equipment 100 may also include a gasket 34, see [link / reference]. Figure 6 and Figure 8 When the first annular portion 311 surrounds the outer periphery of the second annular portion 321, the gasket 34 is disposed on the first end plate 312, and the connector 35 passes through the gasket 34, the first end plate 312, and the second end plate 322 in sequence. The gasket 34 can protect the first end plate 312 and reduce the probability of damage to the first end plate 312.

[0085] When the second annular portion 321 surrounds the outer periphery of the first annular portion 311, the gasket 34 is disposed on the second end plate 322, and the connector 35 passes through the gasket 34, the second end plate 322, and the first end plate 312 in sequence.

[0086] In some embodiments, the second annular portion 321 surrounds the outer periphery of the first annular portion 311, and the inner surface of the second annular portion 321 is provided with a rib 3111 protruding toward the first annular portion 311. The sidewall of the damping member 33 has a notch 33a, and the rib 3111 is inserted into the notch 33a.

[0087] Alternatively, please see Figure 9 and Figure 10 The first annular portion 311 surrounds the outer periphery of the second annular portion 321. The inner surface of the first annular portion 311 has a rib 3111 protruding toward the second annular portion 321. The side wall of the damping member 33 has a notch 33a, and the rib 3111 is inserted into the notch 33a.

[0088] In this embodiment, the cooperation between the rib 3111 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.

[0089] It should be noted that in the embodiment where the second annular portion 321 surrounds the outer periphery of the first annular portion 311, 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.

[0090] Similarly, in the embodiment where the first annular portion 311 surrounds the outer periphery of the second annular portion 321, 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.

[0091] In some embodiments, please refer to Figure 5 The first moving member 31 has a first through hole 313a at one end near the first rod 4, and the first rod 4 passes through the first through hole 313a. The first moving member 31 can rotate at least around the first rod 4 in the circumferential direction.

[0092] That is, the first rod 4 is movably disposed in the first through hole 313a, thereby realizing the connection between the first rod 4 and the first moving part 31.

[0093] The first moving part 31 can rotate at least around the circumference of the first rod 4, including at least two cases:

[0094] 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.

[0095] 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.

[0096] 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.

[0097] For example, such as Figure 5As shown, the sidewall structure of the first through hole 313a is also provided with a first through groove 313b, which penetrates the end faces of the two opposite ends of the first through hole 313a along the axial direction.

[0098] It should be noted that the first through groove 313b penetrates the axial end faces of the first through hole 313a, meaning that the hole wall of the first through hole 313a is disconnected in the circumferential direction, and the first through hole 313a and the first through groove 313b have a certain elastic deformation capability.

[0099] In this embodiment, during the process of the first rod 4 passing through the first through hole 313a, or when the first moving member 31 moves relative to the first rod 4, the first through hole 313a and the first through groove 313b can undergo elastic deformation to adapt to the size of the first through hole 313a required when the first rod 4 is installed or when the first moving member 31 moves relative to the first rod 4.

[0100] In some embodiments, please refer to Figure 5 The second moving member 32 is provided with a second through hole 323a at one end near the second rod 5, and the second rod 5 passes through the second through hole 323a. The second moving member 32 can at least rotate around the second rod 5 in the circumferential direction.

[0101] The second rod 5 is movably disposed in the second through hole 323a, thereby realizing the connection between the second rod 5 and the second moving part 32.

[0102] The second moving part 32 can rotate at least around the circumference of the second rod 5, including at least two cases:

[0103] 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.

[0104] 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.

[0105] 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.

[0106] For example, the sidewall structure of the second through hole 323a is further provided with a second through groove, which penetrates the end faces of the two opposite ends of the second through hole 323a in the axial direction.

[0107] It should be noted that the second through groove penetrates the axial end faces of the second through hole 323a at both ends, meaning that the hole wall of the second through hole 323a is disconnected in the circumferential direction, and the second through hole 323a and the second through groove have a certain elastic deformation capacity.

[0108] Thus, during the process of the second rod 5 passing through the second through hole 323a, or when the second moving member 32 moves relative to the second rod 5, the second through hole 323a and the second through groove can undergo elastic deformation to adapt to the size of the second through hole 323a required when the second rod 5 is installed or when the second moving member 32 moves relative to the second rod 5.

[0109] In some embodiments, such as Figure 6 As shown, the side wall 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 inward at least partially, so that the second rod 5 passes through the second through hole 323a, and the second moving member 32 can rotate around the circumference of the second rod 5. In this embodiment, the second through groove 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 323a.

[0110] In some embodiments, please refer to Figure 6 The garment processing equipment 100 includes a bushing 7, which is disposed in a second through hole 323a, and a second rod 5 passes through the bushing 7 and contacts the bushing 7.

[0111] In this embodiment, the bushing 7 serves two purposes: firstly, it facilitates the insertion of the second rod 5 into the second through hole 323a; secondly, when the second moving part 32 rotates around the second rod 5, the inner wall of the second through hole 323a 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.

[0112] In some embodiments, please refer to Figure 6 The garment processing equipment 100 also includes a vibration damping sleeve 8, with a bushing 7 inserted inside the vibration damping sleeve 8, and the outer periphery of the vibration damping sleeve 8 contacting the wall of the second through hole 323a.

[0113] It is understandable that the bushing 7 can be made of metal. The bushing 7 is set in the second through hole 323a, and the second rod 5 passes through the second through hole 323a. 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.

[0114] In this embodiment, the damping sleeve 8 can isolate the second through hole 323a from the bushing 7, reducing the contact wear between the inner wall of the second through hole 323a 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.

[0115] 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 323a, 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 323a, 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 323a.

[0116] In some embodiments, please refer to Figure 6 The bushing 7 has a second deformation groove 7a on its side wall. The second deformation groove 7a passes through the opposite ends of the side wall of the bushing 7 along the axial direction, so that the bushing 7 can generate radial elastic deformation.

[0117] 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.

[0118] Understandably, the placement of the first rod 4 is not limited.

[0119] For example, in some embodiments, please refer to Figures 1 to 4 The garment processing equipment 100 includes multiple hanging rods 6, one end of each hanging rod 6 is connected to the bucket assembly 2, and the other end is connected to the box 1. The bucket assembly 2 is suspended on the box 1 by the multiple hanging rods 6.

[0120] 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.

[0121] Please see Figure 1 The first rod 4 is part of the hanging rod 6.

[0122] 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.

[0123] 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.

[0124] Understandably, the boom 6 can also be equipped with a vibration damping structure to buffer the vibration of the bucket assembly 2. For example, please refer to... Figure 1 The garment processing equipment 100 includes a damping cylinder 63, a base support 64 disposed at the bottom end of the hanging rod 6, and a vibration damping spring 62. The vibration damping spring 62 passes through the hanging rod 6 and is clamped 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 hanging 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. In this way, when the tub assembly 2 vibrates during washing or spin-drying, the vibration damping spring 62 slides up and down along the hanging rod 6 to absorb the longitudinal vibration energy of the tub assembly 2, thereby reducing the vibration noise of the cabinet 1 and increasing the operational stability of the garment processing equipment 100.

[0125] The number of vibration damping devices 300 is unlimited; for example, please refer to [link to relevant documentation]. 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 barrel assembly 2, and the other end is connected to the hanging rod 6. Thus, the vibration damping components 3 can evenly and fully buffer the vibration of the barrel assembly 2 from different directions, increase the vibration damping effect, and improve the operational safety of the clothing processing equipment 100.

[0126] In other embodiments, please refer to Figure 11 The garment processing equipment 100 includes a workbench 9, which is located 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 connects to the lower part or bottom plate of the housing 1.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] In some embodiments, the garment handling device 100 includes a mounting base disposed on the housing 1, and at least one end of the first rod 4 is disposed on the mounting base.

[0131] 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 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.

[0132] The following combination Figures 1 to 11 The movement mode of the vibration damping component 3 according to an embodiment of this application will be briefly described.

[0133] The first rod 4 is part of the hanger 6, which passes through the first through hole 313a.

[0134] The first moving part 31 is capable of rotating around the circumference of the boom 6, sliding along the extension direction of the boom 6, and swinging up and down relative to the boom 6. The first through hole 313a and the first through groove 313b are capable of providing elastic deformation.

[0135] The second moving member 32 has a second through hole 323a at the end away from the first moving member 31. The second rod 5 passes through the second through hole 323a. The second rod 5 is hollow and has a first deformation groove 5a. The bushing 7 has a second deformation groove 7a. The second rod 5 is stably engaged with the second through hole 323a through the damping sleeve 8 and the bushing 7. The second moving member 32 can rotate around the circumference of the second rod 5.

[0136] The first moving part 31 and the second moving part 32 can rotate relative to each other about their connection point.

[0137] In this embodiment, the vibration damping component 3 has five degrees of freedom of motion: rotational degree of freedom to rotate around the first rod 4, sliding degree of freedom to slide along the extension direction of the first rod 4, degree of freedom to swing up and down relative to the first rod 4, degree of freedom to rotate around the second rod 5, and degree of freedom of relative rotation of the first moving part 31 and the second moving part 32. The vibration damping component 3 has a low probability of motion jamming and can adapt to the vibration displacement of the barrel component 2 in different vibration directions.

[0138] Furthermore, 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. The relatively long lever arm of the force exerted by the second rod 5 on the first rotation axis L2 allows the vibration damping component 3 to move within a larger range, facilitating better absorption of the vibration energy of the barrel assembly 2, that is, reducing the vibration energy transmitted from the barrel assembly 2 to the box 1. In addition, the relatively short distance between the first rod 4 and the first rotation axis L2 helps to reduce the swing space required for the first moving part 31 in the swing plane, resulting in a more compact structure.
