[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application is based on the Chinese patent application with application number 202410254055.9 and application date of March 6, 2024, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field
[0003] The present application relates to the technical field of clothing processing, and in particular to a clothing processing device. Background Art
[0004] Taking a pulsator-type clothing processing device as an example, when the external dimensions of the cabinet remain unchanged, as the washing volume increases, the gap between the barrel assembly and the cabinet becomes smaller and smaller. During the washing or dehydration process, the barrel assembly will vibrate and deflect, and easily hit the cabinet, affecting the safety of the clothing processing device.
[0005] To reduce the vibration amplitude of the tub assembly, clothing processing equipment is equipped with a vibration damper. One end of the damper is connected to the tub assembly and the other end is connected to a suspension rod. The connected end of the damper rotates around the suspension rod or slides along the suspension rod. When the tub assembly vibrates, the damper moves with it to dissipate vibration energy. However, the damper has a high probability of getting stuck when moving with the tub assembly's vibration, affecting the vibration damping effect and potentially causing damage to the damper.

[0040] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the embodiments of the present application.
[0042] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.
[0043] An embodiment of the present application provides a clothing processing device 100 , as shown in FIG. 1 to FIG. 13 , which includes a housing 1 , a barrel assembly 2 , a first rod 4 and a vibration-damping assembly 3 .
[0044] It is understandable that the specific form of the clothing processing device 100 is not limited, and it can be an existing pulsator washing machine, drum washing machine and other equipment, and is not limited here; preferably, the vibration reduction component 3 described in the embodiment of the present application is more effective when used on a pulsator washing machine.
[0045] The barrel assembly 2 is disposed in the box body 1 .
[0046] It is understood that the tub assembly 2 may include an inner tub and an outer tub, with the inner tub disposed within the outer tub, and the space within the inner tub defining a laundry processing 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, the outer tub is used to hold water; when the inner tub is non-perforated, the inner tub itself holds water. In other words, the inner tub can hold both water and laundry, and during the washing process, water in the inner tub does not enter the outer tub. In some embodiments, the tub assembly 2 may consist of only an inner tub, without an outer tub; in this case, the inner tub is a non-perforated inner tub.
[0047] The box body 1 can provide accommodation space and protection for the barrel assembly 2, isolate the barrel assembly 2 from the outside world, and reduce the chance of external dust and other impurities coming into contact with the barrel assembly 2. When the clothing processing device 100 is impacted, the box body 1 can also effectively withstand external impacts and reduce the chance of damage to the barrel assembly 2.
[0048] It can be understood that when the barrel assembly 2 includes an inner barrel and an outer barrel, one end of the vibration-damping assembly 3 can be connected to the outer barrel, and when the clothing processing device 100 includes a suspension rod 6, one end of the suspension rod 6 is connected to the outer barrel, and the other end is connected to the box body 1 to bear the weight of the barrel assembly 2; when the barrel assembly 2 has only an inner barrel, the barrel assembly 2 can include a water receiving tray, and the water receiving tray is arranged outside the inner barrel, and one end of the vibration-damping assembly 3 can be connected to the water receiving tray. When the clothing processing device 100 includes a suspension rod 6, one end of the suspension rod 6 is connected to the water receiving tray, and the other end is connected to the box body 1 to bear the weight of the barrel assembly 2.
[0049] In this embodiment, the barrel assembly 2 including an inner barrel and an outer barrel is taken as an example for description.
[0050] It is understandable that when the clothing processing device is in washing or dehydration mode, the inner barrel rotates, and the clothes in the inner barrel will shift during the rotation of the inner barrel, causing the center of gravity of the inner barrel to shift, thereby causing the inner barrel to rotate eccentrically, resulting in vibration and deflection of the outer barrel. When the eccentricity of the inner barrel rotation increases, the amplitude of the outer barrel will also increase accordingly, making it easy for the barrel assembly to hit the box body, affecting the dehydration process.
[0051] The vibration damping component 3 is a structure with a vibration damping effect. The vibration damping component 3 provided in this embodiment is used to absorb the vibration energy of the barrel component 2 when the clothing processing device 100 is in the washing or dehydration condition, thereby reducing the vibration displacement of the barrel component 2 and reducing the probability of the barrel component 2 colliding with the box body 1.
[0052] Specifically, referring to Figures 1 and 5, the first rod body 4 is arranged outside the barrel assembly 2, and the shock absorbing assembly 3 includes a first connecting end and a second connecting end, the first connecting end is connected to the barrel assembly 2, and the second connecting end is connected to the first rod body 4.
[0053] That is, the vibration reduction assembly 3 is connected to the barrel assembly 2 through the first connection end, and is connected to the components outside the barrel assembly 2 through the second connection end. It is understandable that the barrel assembly 2 can also be provided with a rod to achieve connection with the first connection end through the rod.
[0054] It should be noted that the first rod body 4 is arranged outside the barrel assembly 2, which means that the first rod body 4 is independent of the barrel assembly 2 and is arranged outside the barrel assembly 2. For example, the first rod body 4 can be arranged on the boom 6, the workbench 7 or the box 1, and there is no restriction here.
[0055] At least one of the first connection end and the second connection end has a through hole 32a, and, referring to FIG9 , the hole wall of the through hole 32a extends toward the axis E of the through hole 32a from the axially opposite ends of the through hole 32a toward the middle position of the through hole 32a along its axial direction.
[0056] Specifically, the aperture of the through hole 32a gradually decreases from the opposite two ends along the axial direction to the middle position of the through hole 32a along the axial direction. The aperture of the through hole 32a at the middle position along the axial direction is smaller than the aperture of the through hole 32a at the two ends of the axial direction. The aperture of the through hole 32a is roughly larger at the two ends and smaller in the middle.
[0057] It should be noted that, under the action of the through hole 32 a , the vibration damping assembly 3 has at least the freedom of up and down movement, the freedom of up and down swinging, and the freedom of circumferential rotation.
[0058] When the through hole 32a is provided at the first connection end, the first connection end can move up and down, rotate circumferentially, and swing up and down relative to the tub assembly 2. Specifically, when the laundry processing apparatus 100 is in a washing or dehydration mode, the tub assembly 2 vibrates and deflects, and transmits the vibration energy to the vibration-damping assembly 3. Under the action of the vibration, the first connection end of the vibration-damping assembly 3 moves up and down, rotates circumferentially, and swings up and down relative to the tub assembly 2 to adapt to the changes in the different vibration directions of the tub assembly 2. The vibration of the tub assembly 2 forces the vibration-damping assembly 3 to absorb the vibration energy, thereby suppressing the vibration amplitude of the tub assembly 2.
[0059] When the through hole 32a is provided at the second connecting end, the second connecting end can move up and down along the first rod 4, rotate circumferentially around the first rod 4, and swing up and down relative to the first rod 4. Specifically, when the laundry processing apparatus 100 is in a washing or dehydration mode, the tub assembly 2 vibrates and deflects, and transmits the vibration energy to the vibration reduction assembly 3. Under the action of the vibration, the second connecting end of the vibration reduction assembly 3 moves up and down, rotates circumferentially, and swings up and down relative to the first rod 4 to adapt to the changes in the different vibration directions of the tub assembly 2. The vibration of the tub assembly 2 forces the vibration reduction assembly 3 to absorb the vibration energy, thereby suppressing the vibration amplitude of the tub assembly 2.
[0060] Taking the through hole 32a provided at the second connecting end as an example, the gap between the first rod body 4 and the hole wall of the through hole 32a gradually increases from the middle position of the through hole 32a along its axial direction toward the opposite ends of the through hole 32a along its axial direction. Therefore, when the barrel assembly 2 vibrates and deflects, the through hole 32a can realize the up and down movement of the second connecting end along the first rod body 4 and the circumferential rotation around the first rod body 4, while also providing the second connecting end with a space for up and down swinging. In this way, the second connecting end has multiple degrees of freedom of movement only through the through hole 32a, thereby increasing the working reliability of the vibration reduction assembly 3. In addition, the aperture of the through hole 32a is the smallest at the middle position of the axial direction, which is also convenient for increasing the assembly stability of the through hole 32a and the first rod body 4. It can be understood that in this embodiment, the first rod body 4 has a sufficient extension length to meet the up and down movement stroke of the second connecting end.
[0061] Taking a pulsator-type clothing processing device as an example, when the external dimensions of the cabinet remain unchanged, as the washing volume increases, the gap between the barrel assembly and the cabinet becomes smaller and smaller. During the washing or dehydration process, the barrel assembly will vibrate and deflect, and easily hit the cabinet, affecting the safety of the clothing processing device.
[0062] To reduce the vibration amplitude of the tub assembly, clothing processing equipment is equipped with a vibration damper. One end of the damper is connected to the tub assembly and the other end is connected to a suspension rod. The connected end of the damper rotates around the suspension rod or slides along the suspension rod. When the tub assembly vibrates, the damper moves with it to dissipate vibration energy. However, the damper has a high probability of getting stuck when moving with the tub assembly's vibration, affecting the vibration damping effect and potentially causing damage to the damper.
[0063] In the clothing processing device 100 provided in the embodiment of the present application, when the barrel assembly 2 vibrates and deflects, the vibration-damping assembly 3 achieves up and down movement, circumferential rotation, and up and down swing relative to the barrel assembly 2 or the first rod body 4 through the through hole 32a to adapt to the vibration displacement change of the barrel assembly 2. The end of the vibration-damping assembly 3 connected to the barrel assembly 2 or the end of the vibration-damping assembly 3 connected to a component other than the barrel assembly 2 has at least three degrees of freedom of movement. The vibration-damping assembly 3 has high movement smoothness and low probability of jamming, thereby facilitating the vibration-damping assembly 3 to buffer the vibration of the barrel assembly 2 and reducing the probability of the barrel assembly 2 colliding with the housing 1. In addition, the structure of the through hole 32a alone allows the vibration-damping assembly 3 to have at least three degrees of freedom of movement, which can also make the overall structure of the vibration-damping assembly 3 simpler and easier to manufacture.
[0064] In some embodiments, referring to FIG. 9 , the through hole 32 a is symmetrical about a first plane F, wherein the first plane F is a plane perpendicular to the axis E of the through hole 32 a and passing through the middle position of the through hole 32 a along its axial direction.
[0065] That is to say, the through hole 32a is symmetrical about its axis E and also symmetrical about the first plane F. The through hole 32a is a centrally symmetrical structure, and its center of symmetry is the intersection of the first plane F and its axis E.
[0066] In this embodiment, the structure of the through hole 32a can make the range of motion at different angles more uniform when the first connection end or the second connection end rotates circumferentially and swings up and down, thereby increasing the movement stability of the first connection end or the second connection end. When the barrel assembly 2 returns to a stationary state, it is also convenient for the shock absorbing assembly 3 to follow the barrel assembly 2 to return to its initial position, thereby increasing the movement reliability of the shock absorbing assembly 3.
[0067] In some embodiments, in a longitudinal section passing through the axis E of the through hole 32 a , at least a portion of the cross-section of the hole wall of the through hole 32 a is in an arc shape convex toward the axis E of the through hole 32 a .
[0068] In this embodiment, the cross-sectional shape of the hole wall of the through hole 32a is an arc convex toward the axis E of the through hole 32a. The shape can be entirely arc-shaped, or a figure formed by a combination of arc segments and straight segments or arc segments and curve segments, and there is no limitation here.
[0069] In this way, while allowing the first connection end or the second connection end to have sufficient space for movement, it is also convenient for the first connection end to be stably assembled with the barrel assembly 2 through the through hole 32a, or for the second connection end to be stably assembled with the first rod body 4 through the through hole 32a.
[0070] For example, in some embodiments, please refer to Figure 9, the cross-sectional shape of the hole wall of the through hole 32a is an arc convex toward the axis E of the through hole 32a. The arc can also reduce the movement resistance of the first connection end or the second connection end, making the movement of the first connection end smoother.
[0071] It can be understood that at least a partial cross section may be a partial cross section or a full cross section.
[0072] In some embodiments, as shown in FIG9 , at least a portion of the cross-section of the wall of the through hole 32 a is arc-shaped. This allows for smoother movement of the first or second connection end while also reducing the difficulty of forming the through hole 32 a and the manufacturing difficulty of the vibration damping assembly 3 .
[0073] In some embodiments, referring to Figure 9 , the through hole 32a is disposed at the second connection end. The arc shape is a semicircular arc, and the diameter D1 of the semicircular arc is equal to the thickness D2 of the second connection end, ie, D1 = D2.
[0074] In this embodiment, the diameter of the cross section of the through hole 32a is equal to the thickness of the second connecting end, which can also ensure that when the barrel assembly 2 vibrates and deflects, the second connecting end has a sufficient up and down swing range relative to the first rod body 4 to adapt to the vibration displacement of the barrel assembly 2 in different vibration directions, reduce the probability of movement stagnation of the second connecting end, increase the movement stability of the vibration damping assembly 3, and also reduce the manufacturing difficulty of the vibration damping assembly 3.
[0075] The specific structure of the vibration damping assembly 3 is not limited.
[0076] In some embodiments, please refer to Figures 5 and 6, the vibration reduction assembly 3 includes a first moving member 31, a second moving member 32 and a friction member 33. The first moving member 31 and the second moving member 32 are connected and can rotate relative to each other around the connection between the two. The friction member 33 is arranged at the rotation connection between the first moving member 31 and the second moving member 32, and is used to provide friction force to achieve vibration reduction when the first moving member 31 and the second moving member 32 rotate relative to each other. The end of the first moving member 31 away from the friction member 33 defines a first connection end, and the end of the second moving member 32 away from the friction member 33 defines a second connection end.
[0077] That is, the end of the first moving member 31 away from the friction member 33 is connected to the barrel assembly 2, and the end of the second moving member 32 away from the friction member 33 is connected to the first rod body 4. When the through hole 32a is provided at the first connection end, the first moving member 31 can move vertically, rotate circumferentially, and swing vertically through the through hole 32a; when the through hole 32a is provided at the second connection end, the second moving member 32 can move vertically, rotate circumferentially, and swing vertically through the through hole 32a.
[0078] It should be noted that the friction member 33 refers to a structure whose material itself has friction damping properties.
[0079] It should be noted that the first moving part 31 and the second moving part 32 can rotate relative to each other around the connection between the two, which means that at least one of the first moving part 31 and the second moving part 32 can rotate around the connection between the two, thereby causing the first moving part 31 and the second moving part 32 to rotate relative to each other.
[0080] Specifically, when the barrel assembly 2 vibrates and deflects, while the first moving member 31 or the second moving member 32 has the freedom of vertical movement, circumferential rotation, and vertical swing, the first moving member 31 and the second moving member 32 can also rotate relative to each other about their connection. This provides the vibration damping assembly 3 with at least four degrees of freedom, resulting in smoother movement and further reducing the chance of the vibration damping assembly 3 becoming stuck. Furthermore, when the first moving member 31 and the second moving member 32 rotate relative to each other, they rub against the friction member 33, generating frictional damping. This frictional damping acts as a damping force for the vibration damping assembly 3 to reduce the vibration of the barrel assembly 2, thereby effectively buffering the vibration of the barrel assembly 2.
[0081] In this embodiment, friction is generated by causing the first moving part 31 and the second moving part 32 to rotate relative to each other and rub against the friction part 33, thereby limiting the vibration amplitude of the barrel assembly 2 and reducing the vibration displacement of the barrel assembly 2. The friction part 33 is arranged between the first moving part 31 and the second moving part 32, that is, the friction part 33 does not directly contact the barrel assembly 2 or the first rod body 4, and the wear generated by the friction part 33 can be smaller. At the same time, when the first moving part 31 and the second moving part 32 rotate relative to each other, the friction part 33 can also isolate the first moving part 31 and the second moving part 32, reducing the wear generated by direct friction when the first moving part 31 and the second moving part 32 rotate, and the service life of the vibration damping assembly 3 can also be longer.
[0082] The material of the friction member 33 is not limited. For example, the friction member 33 can be made of a highly wear-resistant polyurethane foam material or a highly wear-resistant soft rubber material, with a high surface friction coefficient and the ability to deform to cooperate with the first moving member 31 and the second moving member 32. Of course, the friction member 33 can also be made of a semi-metallic friction material, etc., and this is not limited here.
[0083] 1 and 8 , the relative rotation axis L2 of the first moving member 31 and the second moving member 32 is substantially parallel to the axis L1 of the barrel assembly 2. That is, the relative rotation axis L2 of the first moving member 31 and the second moving member 32 is substantially parallel to the height direction.
[0084] The term "substantially parallel" means that the angle between the relative rotation axis L2 of the first moving member 31 and the second moving member 32 and the axis L1 of the barrel assembly 2 can be 0° or close to 0°, that is, a certain degree of processing and assembly error is allowed. For example, the angle between the relative rotation axis L2 of the first moving member 31 and the second moving member 32 and the axis L1 of the barrel assembly 2 is 0° to 5°, for example, 0°, 0.3°, 0.5°, 0.7°, 0.9°, 1°, 1.2°, 1.4°, 1.6°, 1.8°, 2°, 3°, 4°, 5°, etc.
[0085] It is understandable that during washing or dehydration, the tub assembly will vibrate both horizontally and vertically, with the horizontal vibration being predominant. The tub assembly's vertical vibration displacement is small and less likely to collide with the tub, while the horizontal vibration displacement is large and easily exceeds the horizontal gap between the housing and the tub assembly, causing collision with the housing. Therefore, it is necessary to effectively suppress the horizontal vibration of the tub assembly. The rotational axes of the first and second moving members of the vibration damping member provided in the related art are generally parallel to the horizontal direction, meaning that the first and second moving members primarily swing along the vertical plane. The damping force on vibration is primarily decomposed into a force along the vertical direction, with a small force component along the horizontal direction. Consequently, the horizontal vibration of the tub assembly cannot be effectively absorbed, resulting in a limited vibration damping effect.
[0086] It can be understood that the horizontal direction refers to the direction parallel to the horizontal plane after the clothes processing apparatus 100 is placed on the horizontal ground, for example, the left-right direction, the front-back direction and other horizontal directions intersecting the left-right direction and the front-back direction.
[0087] In this embodiment, when the barrel assembly 2 vibrates and deflects, the first moving part 31 and the second moving part 32 of the vibration damping assembly 3 can rotate relative to each other around the connection between the two. Since the relative rotation axis L2 of the first moving part 31 and the second moving part 32 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 roughly in the horizontal direction, the friction force generated by the friction part 33 is roughly in the horizontal direction, which can basically be used to reduce the horizontal vibration of the barrel assembly 2, effectively suppress the horizontal vibration of the barrel assembly 2, reduce the vibration displacement of the barrel assembly 2, and reduce the probability of the barrel assembly 2 colliding with the box body 1.
[0088] In some embodiments, please refer to Figure 1, the clothing processing device 100 includes a second rod body 5, the second rod body 5 extends in the height direction and is fixed to the circumferential outer side of the barrel assembly 2, and the end of the first moving part 31 away from the friction part 33 is sleeved on the outer periphery of the second rod body 5 and can rotate around the circumference of the second rod body 5, and the through hole 32a is set at the second connecting end.
[0089] In this embodiment, the through hole 32a is provided at the second connection end, that is, the second moving member 32 can have circumferential rotation freedom, up and down swing freedom, and up and down sliding freedom through the through hole 32a.
[0090] In this embodiment, when the barrel assembly 2 vibrates and deflects, when the vibration energy of the barrel assembly 2 is transmitted to the vibration damping assembly 3, the first moving part 31 is mounted on one end of the second rod body 5 and rotates around the circumference of the second rod body 5, and the second moving part 31 is away from the end of the first moving part 31 and rotates around the circumference of the first rod body 4, swings up and down relative to the first rod body 4, and moves up and down. In addition, the first moving part 31 and the second moving part 32 can rotate relative to each other around the connection between the two. The vibration damping assembly 3 has at least five degrees of freedom of movement, and the probability of movement jamming is low.
[0091] In some embodiments, the first moving member 31 is a rigid member in its entirety and has only one rotational degree of freedom; and / or the second moving member 32 is a rigid member in its entirety.
[0092] It should be noted that a rigid component is a single element of a mechanism, a rigid body that experiences considerable motion with respect to an adjacent component. In mechanics, rigid components are the basic units that comprise a mechanism and have defined relative motion relationships with each other. Degrees of freedom refer to the number of independent coordinates required to describe a mechanical system. One degree of freedom means that the first moving member 31 can move in only one direction; motion in other directions is constrained.
[0093] Specifically, the first moving part 31 has only one rotational degree of freedom, namely the circumferential rotational degree around the second rod body 5. While enabling the entire vibration damping assembly 3 to adapt to changes in the position of the barrel assembly 2 under the action of vibration, it also enables the entire vibration damping assembly 3 to have sufficient installation stability.
[0094] The first moving part 31 is a rigid component as a whole. When the end of the first moving part 31 away from the second moving part 32 rotates around the second rod body 5 in the circumferential direction, it can drive the first moving part 31 as a whole to rotate around the second rod body 5 in the circumferential direction. The second moving part 31 is a rigid component as a whole. When the end of the second moving part 32 away from the first moving part 31 rotates around the first rod body 4 in the circumferential direction, it can drive the second moving part 32 as a whole to move around the first rod body 4 in the circumferential direction, so that the first moving part 31 and the second moving part 32 can rotate relative to each other around the connection between the two.
[0095] The first moving part 31 and the second moving part 32 can be an integral component with a simple structure and are easy to manufacture.
[0096] The installation position of the first rod body 4 is not limited.
[0097] For example, in some examples, please refer to Figure 1, the clothing processing device 100 includes multiple suspension rods 6, one end of each suspension rod 6 is connected to the barrel assembly 2, and the other end is connected to the box body 1, and the barrel assembly 2 is suspended on the box body 1 through multiple suspension rods 6.
[0098] Specifically, the top end of the hanger 6 is fixed to the box body 1, and the bottom end of the hanger 6 is fixed to the barrel assembly 2. The number of hangers 6 can be four, and the top ends of the four hangers 6 correspond to the four corners of the top end of the box body 1, and the bottom ends of the four hangers 6 are fixed to the side walls of the barrel assembly 2 corresponding to the four corners of the box body 1. In this way, each hanger 6 can evenly share the weight of the barrel assembly 2, thereby increasing the installation stability of the clothing processing device 100.
[0099] Please refer to FIG. 1 , the first rod 4 is a part of the suspension rod 6 .
[0100] In this embodiment, the first moving part 31 is connected to the barrel assembly 2, and the second moving part 32 is connected to the suspension rod 6 through the through hole 32a. There is sufficient installation space between the barrel assembly 2 and the suspension rod 6 to arrange the vibration damping assembly 3. The suspension rod 6 has sufficient structural strength to provide sufficient movement support for the vibration damping assembly 3. The second moving part 32 will not fall off the suspension rod 6, thereby increasing the installation stability of the vibration damping assembly 3; in addition, the vibration damping assembly 3 will not be directly connected to the box body 1. The vibration energy of the barrel assembly 2 is transmitted to the box body 1 via the vibration damping assembly 3 and the suspension rod 6, which can reduce the vibration energy received by the box body 1 and increase the operation stability of the clothing processing device 100.
[0101] In this embodiment, the second moving part 32 is mounted on the suspension rod 6. When the barrel assembly 2 vibrates and deflects, under the action of vibration, the end of the second moving part 32 away from the first moving part 31 can slide along the extension direction of the suspension rod 6, rotate circumferentially around the suspension rod 6, and swing up and down relative to the suspension rod 6. The first moving part 31 rotates circumferentially around the second rod body 5, thereby adapting to the changes in different vibration positions of the barrel assembly 2, reducing the probability of movement jamming of the first moving part 31 and the second moving part 32, and the vibration reduction assembly 3 has high working reliability.
[0102] Of course, in other embodiments, the first rod body 4 may also be connected to the suspension rod 6. The suspension rod 6 can provide support for the first rod body 4, thereby providing sufficient support for the second moving member 32.
[0103] It is understood that the suspension rod 6 may also be provided with a vibration-damping structure to cushion the vibration of the tub assembly 2. For example, referring to FIG1 , the laundry processing apparatus 100 includes a damping cylinder 63, a base 64 disposed at the bottom end of the suspension rod 6, and a vibration-damping spring 62. The vibration-damping spring 62 is disposed through the suspension rod 6 and sandwiched between the damping cylinder 63 and the base 64. A connecting slot 2a is formed on the outer peripheral wall of the bottom end of the tub assembly 2, and the connecting slot 2a is mounted on the damping cylinder 63. Specifically, the damping cylinder 63 is mounted on the suspension rod 6, and the vibration-damping spring 62 is a compression spring, with one end of the vibration-damping spring 62 abutting the bottom end of the damping cylinder 63 and the other end abutting the base 64. In this way, when the tub assembly 2 vibrates during the washing or dehydration process, the vibration-damping spring 62 slides up and down along the suspension 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 laundry processing apparatus 100.
[0104] There is no limit to the number of vibration-damping components 3. For example, please refer to Figure 1. There are four vibration-damping components 3 and four second rod bodies 5. One end of the four vibration-damping components 3 is connected to the second rod body 5, and the other end is connected to the suspension rod 6. Therefore, the vibration-damping components 3 can evenly and fully buffer the vibration of the barrel component 2 from different directions, increase the vibration-damping effect, and improve the operating safety of the clothing processing device 100.
[0105] In other examples, please refer to Figure 10, the clothing processing device 100 includes a workbench 7, which is arranged at the top of the box body 1, one end of the first rod body 4 is connected to the workbench 7, and the other end extends downward from the workbench 7 to form a suspended free end, or, after extending downward, is connected to the lower part or bottom plate of the box body 1.
[0106] It can be understood that the workbench 7 is located on the top side of the box body 1, and the workbench 7 has a clothing loading port connected to the clothing processing chamber, that is, the clothes to be washed can be put into the clothing processing chamber from the top side through the clothing loading port, and the washed clothes can also be taken out from the clothing processing chamber through the clothing loading port.
[0107] In this embodiment, the second moving part 32 is connected to the workbench 7 through the first rod body 4, and the first moving part 31 is connected to the barrel assembly 2. The barrel assembly 2 and the workbench 7 jointly provide installation support for the vibration damping assembly 3 to increase the installation stability and movement stability of the vibration damping assembly 3; and the vibration damping assembly 3 is not directly connected to the box body 1. The vibration energy of the barrel assembly 2 is transmitted to the box body 1 through the vibration damping assembly 3 and the workbench 7. The workbench 7 can share part of the vibration energy for the box body 1, reduce the vibration noise of the box body 1, and increase the operation stability of the clothing processing device 100.
[0108] In addition, the first rod 4 extends downward from the workbench 7 , and the axis of the first rod 4 is along the height direction, which can reduce the resistance of the second moving member 32 moving around the first rod 4 .
[0109] In some further examples, referring to FIG. 11 to FIG. 13 , the laundry processing apparatus 100 includes a mounting base 11 , which is disposed on the housing 1 , and at least one end of the first rod 4 is disposed on the mounting base 11 .
[0110] In this embodiment, the first moving part 31 is connected to the box body 1, and the second moving part 32 is connected to the barrel assembly 2. The barrel assembly 2 and the box body 1 jointly provide support for the vibration damping assembly 3. In this way, the vibration damping assembly 3 has sufficient installation space and movement space to facilitate buffering the vibration of the barrel assembly 2.
[0111] There is no limitation on the manner of achieving that the first moving member 31 has only one rotational degree of freedom.
[0112] In some embodiments, referring to FIG. 1 , the barrel assembly 2 includes at least two mounting blocks 21 protruding from the circumferential outer wall of the barrel assembly 2. The two mounting blocks 21 are spaced apart in the height direction. Both ends of the second rod body 5 are fixed to the mounting blocks 21. The first moving part 31 is sleeved on the portion of the second rod body 5 located between the two mounting blocks 21 and abuts against the two mounting blocks 21 respectively.
[0113] In this way, on the one hand, the stability of the second rod body 5 fixed to the barrel assembly 2 can be increased, the probability of the second rod body 5 falling off the barrel assembly 2 can be reduced, and the probability of the first moving part 31 falling off the second rod body 5 can also be reduced. On the other hand, the two mounting blocks 21 constrain the sliding freedom of the first moving part 31 along the extension direction of the second rod body 5, so that the first moving part 31 only has the freedom of movement of circumferential rotation around the second rod body 5.
[0114] The specific structures of the first moving member 31 and the second moving member 32 are not limited.
[0115] In some embodiments, please refer to Figures 5 to 8, the first moving part 31 includes a first connecting seat 311, the second moving part 32 includes a second connecting seat 321, the first connecting seat 311 includes a first annular portion 3111, the second connecting seat 321 includes a second annular portion 3211, the first annular portion 3111 and the second annular portion 3211 are nested and have an annular space in the radial direction, and the friction part 33 is arranged in the annular space.
[0116] It should be noted that the first annular portion 3111 and the second annular portion 3211 are annular structures that are connected end to end and have no gaps in the circumferential direction. The nested arrangement of the first annular portion 3111 and the second annular portion 3211 means that the first annular portion 3111 is embedded in the second annular portion 3211, or the second annular portion 3211 is embedded in the first annular portion 3111; the annular space is the space between the first annular portion 3111 and the second annular portion 3211. The friction member 33 is disposed in the annular space, that is, the friction member 33 is disposed between the first annular portion 3111 and the second annular portion 3211. When the first moving member 31 and the second moving member 32 rotate relative to each other, the first annular portion 3111 and the second annular portion 3211 rotate relative to each other, thereby rubbing against the friction member 33 to generate friction force.
[0117] In this embodiment, the first moving part 31, the second moving part 32 and the friction part 33 are connected together by the nesting cooperation of the first annular part 3111 and the second annular part 3211. The overall structure of the vibration damping assembly 3 is simple and easy to install, and the probability of damage to the friction part 33 during the assembly process can also be reduced.
[0118] In some embodiments, please refer to Figures 5 to 8, the first connecting seat 311 includes a first end plate 3112 connected to the first annular portion 3111, and the second connecting seat 321 includes a second end plate 3212 connected to the second annular portion 3211. The first end plate 3112 and the second end plate 3212 are arranged in parallel, and 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.
[0119] It should be noted that the parallel arrangement of the first end plate 3112 and the second end plate 3212 refers to the positional relationship between the first end plate 3112 and the second end plate 3212 after the first moving part 31 and the second moving part 32 are connected.
[0120] 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. The first annular portion 3111 and the second annular portion 3211 are confined between the first end plate 3112 and the second end plate 3212, thereby increasing the docking stability of the first annular portion 3111 and the second annular portion 3211 and reducing the chance of loosening of the docking of the first annular portion 3111 and the second annular portion 3211. Furthermore, the probability of the friction member 33 escaping from the annular space is reduced, and the friction member 33 is isolated from other components outside the vibration damping assembly 3, thereby improving the installation stability of the vibration damping assembly 3. Furthermore, the first end plate 3112 and the second end plate 3212 are arranged in parallel, further increasing the smoothness of the relative rotation of the first moving member 31 and the second moving member 32.
[0121] In some embodiments, please refer to Figures 5 to 8, the second annular portion 3211 surrounds the outer circumference of the first annular portion 3111, the second end plate 3212 is provided with a through hole 3212a, and the first connecting seat 311 also includes one or more elastic hooks 3113 passing through the internal space of the first annular portion 3111, one end of the elastic hook 3113 is connected to the first end plate 3112, and the other end passes through the through hole 3212a and is connected to the surface of the second end plate 3212 away from the side of the first end plate 3112.
[0122] The elastic hook 3113 refers to a structure that has elasticity and can be deformed.
[0123] Specifically, when the first moving part 31 and the second moving part 32 are docked, the friction part 33 is first set on the outer periphery of the first annular part 3111, and then the through hole 3212a of the second annular part 3211 is passed through the elastic hook 3113 from top to bottom. During the insertion process, the elastic hook 3113 undergoes elastic deformation. When the second annular part 3211 completely surrounds the outer periphery of the first annular part 3111, the elastic hook 3113 extends out of the through hole 3212a, restores the deformation, and abuts against the side of the second end plate 3212 away from the first end plate 3112, thereby connecting the first connecting seat 311 and the second connecting seat 321 together, reducing the probability of the second connecting seat 321 falling off the first connecting seat 311, and increasing the installation stability of the vibration damping assembly 3.
[0124] The number of the elastic hooks 3113 is not limited, and can be one, two, or more than three. For example, referring to FIG. 6 , the number of the elastic hooks 3113 is three.
[0125] Of course, in other embodiments, the first annular portion 3111 surrounds the outer circumference of the second annular portion 3211, the first connecting seat 311 is provided with a through hole, and the second connecting seat 321 includes one or more elastic hooks passing through the internal space of the second annular portion 3211, one end of the elastic hook is connected to the second end plate 3212, and the other end passes through the through hole and is connected to the surface of the first end plate 3112 away from the second end plate 3212.
[0126] In some embodiments, please refer to Figures 5 to 8, the first connecting seat 311 also includes a limiting structure 3114, which is arranged on the first end plate 3112 and is located on the circumferential outside of the first annular portion 3111. The limiting structure 3114 is used to cooperate with the second moving part 32 along the circumferential stop to limit the maximum rotation angle of the second moving part 32 when it rotates relative to the first moving part 31.
[0127] It should be noted that, in the initial state, the angle between the first moving part 31 and the second moving part 32 is the first angle. The initial state is the position of the first moving part 31 and the second moving part 32 when the barrel assembly 2 is in a stationary state. When the barrel assembly 2 vibrates and deflects, the second moving part 32 rotates relative to the first moving part 31. When the second moving part 32 abuts against the limiting structure 3114, the angle between the second moving part 32 and the first moving part 31 is the second angle. The maximum rotation angle of the second moving part 32 relative to the first moving part 31 is the difference between the second angle and the first angle.
[0128] It is understood that the first end of the first moving member 31 is connected to the first end of the second moving member 32, and the angle between the first moving member 31 and the second moving member 32 is 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. The second end of the first moving member 31 is the end of the first moving member 31 away from the friction member 33, and the second end of the second moving member 32 is the end of the second moving member 32 away from the friction member 33.
[0129] It can be understood that when the barrel assembly vibrates and deflects, the first moving part and the second moving part rotate relative to each other under the action of vibration. When the rotation position of the second moving part relative to the first moving part exceeds the critical position, the resistance of the first moving part and the second moving part to return to the initial state is greatly increased, so that they cannot move adaptively according to the change of the vibration position of the barrel assembly, resulting in the inability to effectively suppress the vibration of the barrel assembly and reducing the vibration reduction reliability of the vibration reduction assembly.
[0130] In this embodiment, when the second moving part 32 rotates to the maximum rotation angle relative to the first moving part 31, the second moving part 32 cooperates with the limit structure 3114 to stop it, and the limit structure 3114 prevents the second moving part 32 from rotating in the direction of increasing the relative rotation angle, so as to control the rotation angle of the second moving part 32 relative to the first moving part 31 within an appropriate range, thereby reducing the resistance of the first moving part 31 and the second moving part 32 to return to their initial state, and increasing the vibration reduction reliability of the vibration reduction assembly 3.
[0131] Of course, in other embodiments, the limiting structure can be provided on the second connecting seat 321, and the limiting structure is provided on the second end plate 3212 and is located on the circumferential outside of the second annular portion 3211. The limiting structure is used to cooperate with the first moving part 31 along the circumferential stop to limit the maximum rotation angle of the first moving part 31 when it rotates relative to the second moving part 32.
[0132] In some examples, the angle between the first moving member 31 and the second moving member 32 does not exceed 180°. That is, the 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°.
[0133] 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, the 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 along the same direction, with one of the first moving member 31 and the second moving member 32 as a reference, does not exceed 180°. For example, referring to FIG7 , with the first moving member 31 as a reference, the 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 along the counterclockwise direction shown in the figure does not exceed 180°.
[0134] In this embodiment, the angle setting 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 adaptively move with the vibration position change of the barrel assembly 2, thereby increasing the vibration reduction reliability of the vibration reduction assembly 3.
[0135] In some examples, please refer to Figure 7, when the barrel assembly 2 is in a stationary state, the angle between the first moving part 31 and the second moving part 32, that is, the 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.
[0136] In this embodiment, when the barrel assembly 2 is in a stationary state, the angle between the first moving part 31 and the second moving part 32 is within an appropriate range. On the one hand, it facilitates the relative rotation of the first moving part 31 and the second moving part 32 under the vibration of the barrel assembly 2. On the other hand, it also allows the second moving part 32 to have a sufficient rotation range when rotating relative to the first moving part 31, thereby increasing the vibration reduction reliability of the vibration reduction assembly 3.
[0137] In some examples, the connection position between the first moving part 31 and the second rod body 5 is the first position 3a, and the connection position between the second moving part 32 and the first rod body 4 is the second position 3b. In the plane projection perpendicular to the height direction of the clothing processing device 100, when the barrel assembly 2 is in a stationary state, the line L3 connecting the centers of the projections of the first position 3a and the second position 3b is basically perpendicular to the tangent L4 of the barrel assembly 2 at the first position 3a.
[0138] The term "substantially perpendicular" means that the angle between the line L3 connecting the centers of the projections of the first position 3a and the second position 3b and the tangent line L4 of the barrel assembly 2 at the first position 3a can be 90° or close to 90°, that is, a certain degree of processing and assembly error is allowed. For example, the angle β between the line L3 connecting the centers of the projections of the first position 3a and the second position 3b and the tangent line L4 of the barrel assembly 2 at the first position 3a is 85° to 95°, that is, 85°≤β≤95°, for example, 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95°, etc.
[0139] Taking Figure 4 as an example, the second rod 5 is connected to the barrel assembly 2, the first rod 4 is part of the suspension rod 6, and the angle β is the angle between the line L3 connecting the centers of the projections of the first position 3a and the second position 3b and the tangent L4 of the barrel assembly 2 at the first position 3a.
[0140] In this embodiment, the range of the angle β can ensure that when the barrel assembly 2 is in a stationary state, the vibration damping assembly 3 can also be in a relatively stable state. When the barrel assembly 2 vibrates and deflects, the resistance of the vibration damping assembly 3 when it moves with the vibration of the barrel assembly 2 can also be small, which is convenient for increasing the working reliability of the vibration damping assembly 3.
[0141] The following briefly describes the motion of the vibration reduction assembly 3 according to an embodiment of the present application in conjunction with FIG. 1 .
[0142] The first moving part 31 is sleeved on the second rod body 5, the second rod body 5 is fixed to the barrel assembly 2, the first rod body 4 serves as a part of the suspension rod 6, the through hole 32a serves as a part of the second moving part 32, and the second moving part 32 is sleeved on the suspension rod 6 through the through hole 32a. When the barrel assembly 2 vibrates, the end of the second moving part 32 away from the first moving part 31 can rotate around the circumference of the suspension rod 6, swing up and down relative to the suspension rod 6, and slide along the extension direction of the suspension rod 6. The first moving part 31 can rotate around the circumference of the second rod body 5.
[0143] In this embodiment, the vibration damping assembly 3 has a total of five degrees of freedom of motion, namely, the degree of freedom of rotation around the circumferential rotation of the second rod body 5, the degree of freedom of rotation around the circumferential rotation of the suspension rod 6, the degree of freedom of swinging up and down relative to the suspension rod 6, the degree of freedom of sliding along the suspension rod 6, and the degree of freedom of relative rotation between the first moving part 31 and the second moving part 32. The probability of motion jamming of the vibration damping assembly 3 is low, it can adapt to the vibration displacement of the barrel assembly 2 in different vibration directions, and the vibration reduction reliability is high.
[0144] In the description of this application, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0145] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
