[0042] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] The embodiments of the present application relate to a clothing processing device. Currently, there are many types of clothing processing devices, which are generally divided into washing machines, dryers, dehydrators, etc. according to their functions. Among them, washing machines are divided into pulsator washing machines and drum washing machines according to their driving mode. Drum washing machines are widely popular in the market because they save water and energy, and have a high degree of care for clothes. Furthermore, since washing machines are usually designed for large-scale laundry in households, they are relatively large in size and are not very suitable for single people or users who need to wash small batches of clothes. In this case, a more flexible and space-saving option is a desktop drum washing machine.

[0044] A tabletop drum washing machine is a miniaturized version of a drum washing machine. Its compact size allows it to be placed on a table or countertop, making it ideal for studio apartments, dormitories, or small homes. Despite its size, this type of washing machine retains the gentle, water-saving benefits of a drum washing machine, while also being more convenient and energy-efficient due to its compact size.

[0045] The present embodiment is described below by taking a tabletop drum washing machine as an example of a clothes processing device, and other clothes processing devices can be considered similarly.

[0046] See also Figure 1The clothing processing device 100 includes a base 10 and a drum assembly 20. The base 10 is used to support the drum assembly 20 of the clothing processing device 100 to ensure that the drum assembly 20 does not fall over during operation. The drum assembly 20 is arranged above the base 10. The drum assembly 20 is the core component of the clothing processing device 100 and is used to hold and wash clothes. The drum assembly 20 is tilted upward from the back to the front and has a clothing access opening 20a on the front side. The clothing access opening 20a makes it convenient for users to put clothes into or take them out of the drum assembly 20. Because the tilted upward setting of the drum assembly 20 and the access opening on the front side provide better accessibility and vision, users can easily operate without bending over or squatting, making it more convenient to take clothes in and out.

[0047] The included angle between the central axis BB of the barrel assembly 20 and the horizontal plane may be between 20° and 30°, or may be an inclined angle greater than 30°, which is not limited in the present application.

[0048] The laundry treating apparatus 100 further includes a shock absorbing assembly 30 , which can absorb vibrations generated when the drum assembly 20 rotates at high speed, reduce noise generation, and prevent the laundry treating apparatus 100 from moving or being damaged due to vibrations.

[0049] Please continue reading Figure 1 Specifically, the shock absorbing assembly 30 includes a first damper 31, a second damper 32 and a third damper 33. The top ends of the first damper 31, the second damper 32 and the third damper 33 are all connected to the cylinder assembly 20, and the bottom ends of the first damper 31, the second damper 32 and the third damper 33 are all connected to the base 10 to form a triangular support for the cylinder assembly 20. The triangular support structure constructed by the first damper 31, the second damper 32 and the third damper 33 can more evenly disperse and absorb the vibration and eccentric force generated by the cylinder assembly 20 during high-speed rotation, thereby improving the shock absorption effect, reducing noise and machine movement, and providing stable support for the cylinder assembly 20.

[0050] Because the center of gravity of the drum assembly 20 is typically located in the middle or slightly below, and because clothes are piled at the bottom of the drum assembly 20, the center of gravity tends to be lower. Furthermore, when the laundry processing device 100 is in operation, the movement of the clothes within the drum assembly 20 generates an eccentric force. This force typically acts near the center of the drum, but due to the uneven distribution of clothes, the actual point of application of the eccentric force may be off-center. The clothing access opening 20a is located at the front of the drum. Therefore, when the eccentric force acts, it has a more direct impact on the clothing access opening 20a, causing the opening 20a to wobble more noticeably.

[0051] To this end, the first damper 31 in this embodiment is positioned closer to the clothing access opening 20a than the second damper 32 and the third damper 33. This allows it to more directly counteract the torque generated by the eccentric distribution of clothing. This torque tends to cause the drum assembly 20 to rotate about its support point, but the proximity of the first damper 31 helps counteract this rotational tendency, providing additional support and shock absorption, thereby reducing sway at the clothing access opening 20a. By providing an additional support point near the clothing access opening 20a, the clothing treatment device 100's resistance to eccentric forces is enhanced, improving the overall stability of the clothing treatment device 100.

[0052] Understandably, considering the small size and limited internal space of the tabletop drum washing machine 22, it is impossible to set more dampers or add too many counterweights. This embodiment optimizes the number and layout of the shock absorbing components 30 to achieve the purpose of improving the stability of the washing machine without adding too much weight and providing effective shock absorption in a limited space.

[0053] Furthermore, the first damper 31, the second damper 32, and the third damper 33 can be at least one of a hydraulic damper or a gas-liquid damper. Each damper is equipped with a PU (polyurethane) friction plate to increase the friction of the shock-absorbing assembly 30, thereby enhancing the damping effect. An internal airflow duct is also provided to control the flow of gas, thereby adjusting the damping force. This allows the first damper 31, the second damper 32, and the third damper 33 to provide a stable damping effect under different loads and speeds, making it ideal for applications requiring precise control of vibration and displacement, such as the shock-absorbing system of the laundry treatment device 100.

[0054] like Figure 1 As shown, in some embodiments, the drum assembly 20 includes an outer drum 21 and a drum 22. The drum 22 is rotatably disposed in the outer drum 21. The outer drum 21 can protect the internal drum 22 and the clothes from being affected by the external environment, while the clothes are washed and dehydrated in the drum 22. The rotation of the drum 22 can make the clothes evenly distributed during the washing process, and during dehydration, the water in the clothes can be thrown out by centrifugal force to achieve a dehydration effect.

[0055] In some embodiments, the extended central axes of the first damper 31, the second damper 32, and the third damper 33 intersect at the center of mass A of the cylinder assembly 20, which helps to more evenly distribute and balance the forces acting on the cylinder assembly 20 and reduce local stress. This allows the first damper 31, the second damper 32, and the third damper 33 to more effectively absorb and disperse the vibration of the cylinder assembly 20, thereby improving the shock absorption effect of the shock absorbing assembly 30.

[0056] See also Figure 1 and Figure 2In some embodiments, along the front-to-back direction EE, the drum assembly 20 can be divided into a front portion 20b and a rear portion 20c with the center of mass A of the drum assembly 20 as the boundary. The top end of the first damper 31 is connected to the front portion 20b. The first damper 31 can more effectively absorb and reduce the shaking of the front portion 20b caused by the eccentric distribution of clothes and the taking and placing action, which helps to enhance the stability of the drum assembly 20 at the clothing taking and placing port 20a.

[0057] The top end of the second damper 32 is connected to the rear portion 20c, absorbing and dispersing vibrations transmitted from the rear portion 20c, reducing the impact on the drum assembly 20. This connection also helps balance the weight distribution of the drum assembly 20, providing additional support when laundry is unevenly distributed. Furthermore, its location to the left of the third damper 33 helps disperse and balance torsional forces generated by eccentric forces, thereby improving the stability of the laundry treatment apparatus 100.

[0058] The top end of the third damper 33 is connected to the rear portion 20c and is located on the right side of the second damper 32. The third damper 33 cooperates with the second damper 32 to more evenly disperse the weight and eccentric force of the barrel assembly 20 and improve the torsional performance of the barrel assembly 20. The third damper 33 can offset the torsional force generated by the eccentric force and reduce the rotation or swing of the barrel assembly 20.

[0059] By connecting the first damper 31, the second damper 32 and the third damper 33 to the front 20b and the rear 20c of the drum assembly 20 respectively, and reasonably distributing them on the left and right sides, more uniform force distribution and more effective shock absorption can be achieved, thereby improving the service life of the clothing processing device 100.

[0060] In one configuration, along the front-rear direction EE, the first damper 31 can be tilted downward from the back to the front, that is, the first damper 31 is supported on the cylinder assembly 20 (eg, Figure 3 As shown in the figure, the top end of the first damper 31 is arranged closer to the rear than the bottom end, and it can absorb the shaking at the clothing access opening 20a more directly because this inclination angle helps to better align and absorb the force transmitted from the clothing access opening 20a.

[0061] In another arrangement, along the front-rear direction EE, the first damper 31 can be arranged upwardly and tilted from the back to the front, that is, the first damper 31 can be supported on the cylinder assembly 20 (eg, Figure 4 As shown, the bottom end of the first damper 31 is positioned closer to the rear than the top end, so that the first damper 31 occupies less space in front of the laundry processing apparatus 100, thereby achieving a more compact structure and facilitating the miniaturization of the tabletop drum washing machine 22. It is understood that the present application does not impose any restrictions on the configuration of the first damper 31.

[0062] Regardless of whether the first damper 31 is supported from front to back or from back to front, the force generated by the shaking of the clothing loading port acts on the first damper 31, and is decomposed into a force that causes the first damper 31 to rotate and a force that causes the first damper 31 to expand and contract, so that the first damper 31 rotates downward on the one hand and contracts on the other hand, which can absorb greater shaking and withstand greater force, thereby improving the reliability and shock absorption effect of the first damper 31.

[0063] See also Figure 1 and Figure 2 In some embodiments, the first damper 31 is located between the second damper 32 and the third damper 33 along the left-right direction (FF). Unlike the mutually coordinated arrangement of the second damper 32 and the third damper 33 along the left-right direction (FF), since the first damper 31 is close to the laundry inlet, this area may experience greater torsional forces during operation of the laundry treatment apparatus 100. The central arrangement helps provide additional torsional support, reduces torsional vibration of the drum, and reduces the individual pressure on the second damper 32 and the third damper 33 on either side, thereby improving the overall shock absorption effect.

[0064] Furthermore, the center axis CC of the first damper 31 lies within the vertical plane of the center axis BB of the drum assembly 20. This provides direct support along the center axis of the drum assembly 20, helping to reduce vibration caused by eccentric placement of clothing and resisting bending or twisting caused by eccentric forces. When the first damper 31 is aligned with the center axis BB of the drum assembly 20, it can more effectively absorb and offset eccentric forces.

[0065] The second damper 32 and the third damper 33 can be symmetrically arranged about the vertical plane where the central axis BB of the drum assembly 20 is located. The symmetrically arranged second damper 32 and the third damper 33 help to provide uniform support, can uniformly absorb and disperse the force acting on the drum assembly 20, and ensure the symmetry and balance of the clothing processing device 100 during operation. The symmetrical layout helps to absorb and reduce vibration more effectively, can respond to the unbalanced forces on both sides at the same time, provide better shock absorption effect, and reduce vibration and swing caused by load asymmetry.

[0066] Please continue reading Figure 1In some embodiments, the top end of the second damper 32 is inclined toward the third damper 33 relative to the bottom end, and the top end of the third damper 33 is inclined toward the second damper 32 relative to the bottom end, that is, along the left and right directions FF, the second damper 32 and the third damper 33 are supported on the cylinder assembly 20 in an "eight" shape, providing a wider support base, which can provide better shock absorption effect, and can effectively disperse and resist forces and vibrations in different directions, especially the forces along the left and right directions FF, which helps to improve the torsional performance of the cylinder assembly 20, provide support from both sides, and reduce torsion caused by eccentric loads.

[0067] like Figure 1 As shown, specifically, the second damper 32 satisfies one of the following conditions:

[0068] The bottom end of the second damper 32 is located outside the projection of the drum assembly 20 on the base 10. That is, the second damper 32 is arranged upwardly and obliquely from the bottom end of the second damper 32 toward the drum assembly 20. This can expand the support range of the second damper 32, provide a wider support base, and help improve the stability of the laundry processing apparatus 100.

[0069] The angle α between the central axis DD of the second damper 32 and the horizontal plane satisfies the following: 70°≤α≤80°. When the angle DD between the central axis DD of the second damper 32 and the horizontal plane is less than 70°, meaning the second damper 32 is tilted closer to the base 10, the force acting on the second damper 32 is more dispersed into downward force, placing a greater burden on the bottom end of the second damper 32 and increasing the risk of breakage. When the angle DD between the central axis DD of the second damper 32 and the horizontal plane is greater than 80°, meaning the second damper 32 is tilted closer to vertical, the angle with the horizontal plane increases, resulting in more force acting on the connection point between the second damper 32 and the cylinder assembly 20, leading to the risk of excessive swing or damage to the cylinder assembly 20. Therefore, setting α between 70° and 80° can more effectively balance the downward pressure and the force in the left-right direction (FF), ensuring that the second damper 32 can more effectively support the cylinder assembly 20 and provide good shock absorption.

[0070] The vertical plane where the central axis DD of the second damper 32 is located is perpendicular to the vertical plane where the central axis BB of the barrel assembly 20 is located, which can better withstand the lateral force of the barrel assembly 20 along the left and right directions FF, reducing safety hazards of the barrel assembly 20 during use, such as tipping over or excessive swinging.

[0071] It is understandable that the third damper 33 may be configured similarly to the second damper 32 , and details thereof will not be repeated herein.

[0072] like Figure 1 and Figure 2As shown, in actual application, the bottom ends of the second damper 32 and the third damper 33 are both located outside the projection of the barrel assembly 20 toward the base 10, and are symmetrically arranged about the vertical plane where the central axis BB of the barrel assembly 20 is located. The vertical planes where the central axes of the second damper 32 and the third damper 33 are located are both perpendicular to the vertical plane where the central axis BB of the barrel assembly 20 is located, and the angles between the central axes and the horizontal plane are both 75°. The top ends of the second damper 32 and the third damper 33 are both connected to the rear part 20c, specifically at a position 8 mm away from the center of mass A of the barrel assembly 20, so that the second damper 32 and the third damper 33 provide sufficient supporting force to resist the shaking caused by eccentric force, and the supporting force on both sides of the barrel assembly 20 is balanced, which helps to maintain the balance of the barrel assembly 20.

[0073] like Figure 3 and Figure 4 As shown, in some embodiments, the first damper 31 is movably connected to the front portion 20b and / or the base 10. The movable connection allows the connection between the first damper 31 and the front portion 20b and / or the base 10 to move within a certain range, providing additional flexibility, so that the first damper 31 can adapt to different load conditions and the operating conditions of the cylinder assembly 20, and the first damper 31 can dynamically adjust its position according to the force conditions, more effectively absorb and decompose vibrations, and improve the shock absorption effect of the first damper 31.

[0074] Specifically, the first damper 31 is rotatably connected to the front portion 20b and the base 10, allowing the first damper 31 to rotate appropriately, flexibly responding to vibrations and eccentric forces in different directions, and adaptively adjusting the operating state of the cylinder assembly 20 to maintain a better shock absorption effect.

[0075] It can be understood that in one setting, the second damper 32 is movably connected to the rear portion 20c and / or the base 10, that is, the second damper 32 is allowed to have a certain range of motion when absorbing vibrations, which helps to more effectively absorb and decompose vibrations, and can reduce stress concentration at the connection between the second damper 32 and the rear portion 20c and / or the base 10, thereby extending the service life of the second damper 32 and reducing fatigue damage caused by vibrations.

[0076] In another configuration, the third damper 33 is movably connected to the rear portion 20c and / or the base 10, and the effects are the same as described above, which will not be described again.

[0077] Specifically, the second damper 32 is rotatably connected to the rear portion 20c and the base 10, and the third damper 33 is rotatably connected to the rear portion 20c and the base 10, allowing the second damper 32 and the third damper 33 to rotate appropriately, flexibly responding to vibrations and eccentric forces in different directions, and adaptively adjusting the operating state of the cylinder assembly 20 to maintain a better shock absorption effect.

[0078] like Figure 1 As shown, in some embodiments, the barrel assembly 20 further includes a first lug 23, a second lug 24 and a third lug 25, all of which are connected to the side of the outer barrel 21 close to the base 10, wherein the top end of the first damper 31 is rotatably connected to the first lug 23, the top end of the second damper 32 is rotatably connected to the second lug 24, and the top end of the third damper 33 is rotatably connected to the third lug 25. The first lug 23, the second lug 24 and the third lug 25 are all arranged on the side of the outer barrel 21 close to the base 10. Compared with the first lug 23, the second lug 24 and the third lug 25 being arranged on the side of the outer barrel 21 away from the base 10, the connection path of the first damper 31, the second damper 32 and the third damper 33 is shortened, which can enhance the structural rigidity of the first damper 31, the second damper 32 and the third damper 33, more effectively support the barrel assembly 20, and reduce deformation and bending. Furthermore, the force transmission is more direct, so that the supporting and shock absorbing effects of the first damper 31 , the second damper 32 and the third damper 33 are more significant.

[0079] See also Figure 1 and Figure 5 Specifically, the first lug 23 has a first clamping space 23a and a first connecting hole 23b communicating with the first clamping space 23a. The top end of the first damper 31 is located in the first clamping space 23a and has a second connecting hole 31a. The clothing processing device 100 also includes a first pin shaft 40, which is passed through the first connecting hole 23b and the second connecting hole 31a, so that the first damper 31 is rotatably connected to the first lug 23, that is, the first damper 31 can rotate relative to the first lug 23 within a certain range, providing the necessary flexibility, so that the first damper 31 can respond to vibration forces in different directions, so that the vibration forces in all directions can increase the telescopic movement stroke of the first damper 31, thereby increasing the friction work done during the telescopic movement of the first damper 31, so that the first damper 31 can effectively consume and weaken the vibration kinetic energy in all directions, thereby improving the shock absorption effect.

[0080] It is understandable that the connection method between the top end of the second damper 32 and the second lug 24, and the connection method between the top end of the third damper 33 and the third lug 25 may be the same as or different from the connection method between the top end of the first damper 31 and the first lug 23 mentioned above, and this application does not impose any restrictions on this.

[0081] See also Figure 5 Furthermore, the base 10 includes a bottom plate 11 having a second clamping space 11a and a third connection hole 11b communicating with the second clamping space 11a. The bottom end of the first damper 31 is located within the second clamping space 11a and has a fourth connection hole 31b. The laundry processing device 100 also includes a second pin 50, which is inserted through the third connection hole 11b and the fourth connection hole 31b. The second clamping space 11a provides stable positioning for the bottom end of the first damper 31, maintaining it in the correct position. The second pin 50, which is inserted through the third connection hole 11b and the fourth connection hole 31b, allows the bottom end of the first damper 31 to rotate relative to the base 10, providing the necessary flexibility. The provision of the second pin 50 simplifies assembly and maintenance. When the first damper 31 needs to be replaced or maintained, only the second pin 50 needs to be removed.

[0082] Furthermore, the base 10 also includes a mounting seat 12, which is detachably connected to the bottom plate 11 and is located above the bottom plate 11, wherein the bottom plate 11 and the mounting seat 12 are made of different materials. The bottom plate 11 can be a steel plate bottom plate 11 or an aluminum alloy bottom plate 11, which has high strength and rigidity and can support the weight of the drum assembly 20, and the mounting seat 12 can be a PUM (polyurethane material) mounting seat 12, which can effectively absorb the vibration transmitted by the drum assembly 20 and improve the smooth operation of the clothing processing device 100.

[0083] Please continue reading Figure 5 The mounting base 12 has a third clamping space 12a and a fifth connection hole 12b connected to the third clamping space 12a. The bottom end of the second damper 32 is located in the third clamping space 12a and has a sixth connection hole. The laundry processing device 100 also includes a third pin 60, which is inserted into the fifth connection hole 12b and the sixth connection hole. The mounting base 12 provides a stable platform for fixing the second damper 32. The third clamping space 12a ensures that the bottom end of the second damper 32 is properly positioned, reducing displacement or shaking during the operation of the drum assembly 20 and improving the shock absorption effect. The insertion of the third pin 60 provides a simple and reliable connection method that can withstand large dynamic loads.

[0084] It is understandable that the connection method between the bottom end of the third damper 33 and the base 10 may be the same as or different from the connection method between the second damper 32 and the base 10, and this application does not impose any limitation on this.

[0085] In some embodiments, the clothing processing device 100 further includes a frame assembly (not shown), the frame assembly having a accommodating cavity, and the drum assembly 20 is disposed in the accommodating cavity. The frame assembly serves as a sturdy supporting structure to enhance the structural rigidity of the entire clothing processing device 100 and reduce deformation and vibration during high load or high-speed operation.

[0086] like Figure 4 and Figure 5 As shown, the shock absorbing assembly 30 also includes a first suspension spring 34 and a second suspension spring (not shown). One end of the first suspension spring 34 is connected to the side of the cylinder assembly 20 away from the base 10, understandably, specifically connected to the side of the outer cylinder 21 away from the base 10, and the other end is connected to the frame assembly. Similarly, one end of the second suspension spring is connected to the outer peripheral wall of the cylinder assembly 20 away from the base 10, specifically connected to the outer peripheral wall of the outer cylinder 21 away from the base 10, and the other end is connected to the frame assembly. Since the first suspension spring 34 and the second suspension spring can generate elastic deformation, the elastic deformation is used to offset the vibration energy, reduce the vibration generated by the cylinder assembly 20 during operation, and thereby reduce the force transmitted to the frame assembly.

[0087] The frame assembly includes an upper beam, which is arranged opposite the base 10. The other ends of the first and second suspension springs 34 and 33 are both connected to the upper beam. Specifically, the first and second suspension springs 34 and 33 provide suspension force for the barrel assembly 20, allowing the barrel assembly 20 to have a certain amount of vertical movement. The first and second suspension springs 34 and 34 are responsible for absorbing and buffering vertical vibration and impact forces, and provide flexible support to prevent the barrel assembly 20 from being damaged by excessive vibration. The first and second suspension springs 34 and 33 work in conjunction with the first, second, and third dampers 31, 32, and 33 to provide a comprehensive shock absorption effect.

[0088] The second suspension spring and the first suspension spring 34 are respectively arranged on the left and right sides of the vertical plane of the central axis BB of the drum assembly 20, which can more evenly absorb and disperse the vibration generated by the drum assembly 20 during operation, thereby improving the overall shock absorption effect. By arranging the first suspension spring 34 and the second suspension spring on both sides, a more stable support is provided for the drum assembly 20, reducing shaking caused by eccentric force or unbalanced load, thereby improving the stability of the laundry processing device 100.

[0089] Please continue reading Figure 4 and Figure 5Furthermore, the cylinder assembly 20 also includes a first hanging ear 26 and a second hanging ear (not shown). The first hanging ear 26 is arranged on the side of the cylinder assembly 20 away from the base 10 and is connected to the first suspension spring 34, while the second hanging ear is arranged on the side of the cylinder assembly 20 away from the base 10 and is connected to the second suspension spring. The first hanging ear 26 and the second hanging ear provide elastic support for the first suspension spring 34 and the second suspension spring respectively. The first hanging ear 26 and the second hanging ear are arranged on the outer peripheral wall of the cylinder assembly 20 away from the base 10, closer to the upper beam of the frame assembly, so that the suspension layout of the first suspension spring 34 and the second suspension spring is more compact, more directly absorbs the vertical vibration of the cylinder assembly 20, and reduces the direct pressure of the cylinder assembly 20 on the base 10, and cooperates with the first damper 31, the second damper 32 and the third damper 33 to more evenly distribute the load of the cylinder assembly 20.

[0090] Furthermore, both the first and second mounting ears 26 and 27 are located on the outer surface of the rear portion 20c, helping to more evenly distribute the load of the drum assembly 20. This, in particular, reduces vibration caused by uneven loading during high-speed rotation or dehydration. Specifically, the first and second mounting ears 26 and 27 are positioned 1 mm from the center of mass A. This, in conjunction with the first damper 31, provides support and shock absorption in various directions, thereby enhancing the overall stability of the drum assembly 20.
