Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing devices, and more specifically, to a damper, a vibration reduction structure and a wall-mounted washing machine. Background Art

[0002] In existing wall-mounted washing machines, the vibration of the inner drum is directly transmitted to the outer drum through bearings, and then to the wall. To reduce the vibration transmitted from the wall-mounted washing machine to the wall, ensure the reliability and safety of the connection between the wall-mounted washing machine and the wall, and reduce noise, the existing technology generally uses a program to control the inner drum speed. The speed is set based on the eccentricity of the inner drum rotation feedback to avoid excessive vibration and excessive vibration transmitted to the wall. However, this method of setting the speed by controlling the eccentricity of the inner drum feedback to avoid excessive vibration being transmitted to the wall results in clothes with large eccentricities being dehydrated only at low speeds, resulting in increased dehydration time and less than ideal dehydration results.

[0003] However, if a damper is used to reduce vibration in a wall-mounted washing machine, the conventional damper's expansion and contraction direction corresponds to the damping direction. This makes it unable to adapt to the vibrations generated by the shear, torsional, and bending forces generated by the rotating inner drum, thus affecting the vibration reduction effect. Furthermore, the conventional damper is arranged along the circumference of the inner and outer drums, making the overall circumferential dimensions of the wall-mounted washing machine excessively large, defeating the original purpose of saving space. Summary of the Invention

[0004] This application is based on the inventor's discovery and understanding of the following problems and facts: the telescopic direction of the existing damper is the vibration reduction direction of the damper, which cannot adapt to the vibration caused by the shear force, torsional force and bending force generated when the inner cylinder rotates, affecting the vibration reduction effect and occupying a large wall area.

[0005] The embodiments of the present application aim to solve at least one of the above technical problems to a certain extent.

[0006] According to a first aspect of an embodiment of the present application, a damper is provided, comprising: a first rod having a first end A and a second end A opposite to each other; an interior of the first rod having a sliding track extending in the same direction as the first rod and having an opening at the first end A;

[0007] a second rod body, the second rod body having a first end B and a second end B opposite to each other, the first end B of the second rod body passing through the opening and being slidably disposed in the sliding track;

[0008] a first connecting member, the first connecting member having a first end C and a second end C opposite to each other, the first end C of the first connecting member being used to connect to the vibration generating component, the second end C of the first connecting member being movably connected to the second end B of the second rod body with multiple degrees of freedom, so that the first connecting member can rotate circumferentially relative to the axis of the second rod body about the second end B;

[0009] a second connecting member, the second connecting member having a first end D and a second end D opposite to each other, the first end D of the second connecting member being used to connect to the vibration receiving component, the second end D of the second connecting member being movably connected to the second end A of the first rod body with multiple degrees of freedom, so that the second connecting member can rotate circumferentially relative to the axis of the first rod body about the second end A;

[0010] a spring disposed between the first connecting member and the second connecting member;

[0011] Wherein, when the first connecting member and the second connecting member have a movement tendency to move toward each other, the spring has a thrust force to push the first connecting member and the second connecting member away from each other;

[0012] When the first connecting member and the second connecting member have a tendency to move away from each other, the spring has a pulling force to pull the first connecting member and the second connecting member toward each other;

[0013] When the first connecting member and / or the second connecting member has a tendency to rotate circumferentially relative to the first rod body, the spring has an elastic force to drive the first connecting member and / or the second connecting member to restore to be coaxial with the first rod body.

[0014] The damper has tensile and compressive vibration reduction effects, bending vibration reduction effects, shear vibration reduction effects and torsional vibration reduction effects, which can achieve better vibration reduction and support effects. The damper can be applied to the vibration reduction structure to connect the inner and outer drums of the wall-mounted washing machine. When the inner drum rotates and generates vibration, the vibration transmitted from the inner drum to the outer drum can be effectively reduced, which not only makes the connection between the outer drum and the wall more stable and reliable, but also effectively reduces noise.

[0015] In some embodiments, the multi-degree-of-freedom movable connection between the second end C of the first connector and the second end B of the second rod body adopts a ball joint connection structure or a composite hinge connection structure;

[0016] The multi-degree-of-freedom movable connection between the second end D of the second connecting member and the second end A of the first rod body adopts a ball joint connection or a compound hinge connection.

[0017] The proposed multi-DOF articulation can be achieved using a ball joint. Alternatively, a composite hinge can be used instead. A composite hinge is a revolute pair consisting of three or more components connected to two or more coaxial axes. Using the same bearing structure as a ball joint, it offers the advantages of flexible and accurate control and a wide range of torsion angles.

[0018] In some embodiments, a first shell is provided on the periphery of the first connecting member, and a second shell is provided on the periphery of the second connecting member;

[0019] The spring is a linear stiffness spring, one end of the spring along the expansion and contraction direction is connected to the first shell, and the other end of the spring is connected to the second shell.

[0020] The spring is connected to the first connecting member and the second connecting member through the first shell and the second shell. The spring can enable the first connecting member and the second connecting member to quickly return to their original position after rotation, thereby absorbing vibration.

[0021] In some embodiments, the sliding track of the first rod body is filled with damping oil.

[0022] According to an embodiment of the second aspect of the present invention, there is provided a vibration damping structure, comprising:

[0023] Multiple dampers are arranged side by side in two groups along the axial direction, and each group of dampers has multiple dampers arranged at intervals along the circumferential direction. Each damper is extended radially, and the ends of each damper that are close to each other are used to connect with the vibration generating component, and the ends that are away from each other are used to connect with the vibration receiving component.

[0024] In some embodiments, one of the two groups of dampers arranged side by side is a front damper assembly, and the other group is a rear damper assembly. The front dampers are used to support the vibration generating component, and the rear dampers are used to form a torque at the connection point between them and the vibration generating component.

[0025] The front row damper close to the inner tube in the double-row damper can act as a fulcrum, while the rear row damper facing away from the inner tube will form a torque at the fulcrum, thereby balancing the torque formed by the centrifugal force of the inner tube, thereby achieving stable operation of the inner tube and achieving effective vibration reduction effect.

[0026] According to an embodiment of a third aspect of the present invention, there is provided a wall-mounted washing machine, comprising:

[0027] An inner cylinder, an outer cylinder, and a vibration-damping structure disposed between the inner cylinder and the outer cylinder;

[0028] The vibration reduction structure includes: the aforementioned damper;

[0029] A bearing seat is provided at the bottom of the inner cylinder, one end of the bearing seat along the axial direction of the inner cylinder is connected to the inner cylinder, and the other end passes through the rear wall of the outer cylinder;

[0030] The vibration-damping structure is arranged between the inner cylinder and the outer cylinder. The dampers of the vibration-damping structure are arranged side by side in two groups along the axial direction of the outer cylinder. The multiple dampers in each group are arranged around the inner cylinder and the outer cylinder along the circumferential direction of the outer cylinder. The two rows of dampers are arranged axially between the inner and outer cylinders, which reduces the circumferential size of the wall-mounted machine and saves wall space.

[0031] Each damper has one end close to the bearing seat along the radial direction of the outer cylinder connected to the bearing seat, and one end close to the outer cylinder connected to the outer cylinder.

[0032] The damper can absorb the vibration of the bearing seat, preventing the mounting seat from vibrating significantly along with the inner tube, affecting the stability of the connection between the mounting seat and the wall, and reducing noise.

[0033] In some embodiments, one of the two groups of dampers arranged side by side along the axial direction of the outer cylinder is a front damper assembly, and the other group is a rear damper assembly. The front damper assembly is closer to the front side of the inner cylinder than the rear damper assembly. The front dampers are used to support the inner cylinder, and the rear dampers are used to generate a torque at the connection point between the front dampers and the inner cylinder to balance the torque generated by centrifugal force when the inner cylinder rotates.

[0034] The front row of dampers close to the inner tube in the two rows of dampers can act as a fulcrum, while the rear row of dampers facing away from the inner tube will form a torque at the fulcrum, thereby balancing the torque formed by the centrifugal force of the inner tube, thereby achieving stable operation of the inner tube and achieving effective vibration reduction effect.

[0035] In some embodiments, a mounting seat is provided on the outer circumference of the bottom of the outer cylinder, and the mounting seat is used to connect to the external wall;

[0036] A bearing seat is provided at the bottom of the inner cylinder, one end of the bearing seat along the axial direction of the inner cylinder is connected to the inner cylinder, and the other end passes through the rear wall of the outer cylinder and is located on the inner side of the mounting seat;

[0037] The damper is arranged between the mounting seat and the bearing seat, one end of the damper is connected to the part of the bearing seat located inside the mounting seat, and the other end is connected to the mounting seat.

[0038] In some embodiments, a rubber seal is provided between the mounting seat and the rear wall of the outer tube, so that the mounting seat and the outer tube are flexibly connected;

[0039] The rubber seal is arranged side by side with the damper and is located at the front side of the damper along the axial direction of the inner cylinder.

[0040] Not only can it further reduce the vibration transmitted from the inner cylinder to the outer cylinder, but it can also disassemble and assemble the rubber seal when the internal space needs to be cleaned, which is convenient for later maintenance operations. The rubber seal can also provide certain support for the mounting seat.

[0041] In some embodiments, a pre-tightening screw is threadedly connected to the mounting seat along the radial direction of the outer cylinder, and the pre-tightening screw passes through the mounting seat and is connected to the damper.

[0042] In some embodiments, the spring preload force of the damper is greater than the gravity of the inner drum in a fully loaded static condition.

[0043] By using a pre-tightening screw, the spring of the damper can be stretched, thereby achieving damper pre-tightening, which can ensure that the damper displacement is small or even does not deform under the action of gravity. Moreover, the six-degree-of-freedom damper is always in a stretched state within the static working condition of the rated load of the inner tube, which can ensure the stability of the vibration reduction performance.

[0044] According to the damper of an embodiment of the present invention, the second rod body can telescope and slide in the sliding track of the first rod body, and the first connecting member is movably connected to the second rod body with multiple degrees of freedom, and the second connecting member is movably connected to the first rod body with multiple degrees of freedom, so that the first connecting member can rotate around the second rod body, and the second connecting member can rotate around the first rod body, so that the damper can not only have vibration reduction and support functions along the extension and contraction direction, but also have the ability of tension, compression, bending, shearing and torsion under a certain load, wherein the second rod body realizes tension and compression vibration reduction under the action of the sliding track resistance and the elastic force and pressure of the spring, and the multi-degree-of-freedom movably connection of the first connecting member and the second connecting member realizes bending vibration reduction, shear vibration reduction and torsional vibration reduction in cooperation with the elastic force of the spring, so that the damper can have a better vibration reduction effect, and a vibration reduction structure can be formed by the damper to effectively reduce the vibration of the wall-mounted washing machine, thereby preventing the vibration generated by the wall-mounted washing machine from being transmitted to the wall, and can improve the reliability and safety of the connection between the wall-mounted washing machine and the wall without reducing the rotation speed of the inner drum, and can also achieve noise reduction.

[0045] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The vibration of the inner drum of the existing wall-mounted washing machine is directly transmitted to the outer drum through the bearing, and then transmitted to the wall.

[0060] In order to reduce the vibration transmitted from the wall-mounted washing machine to the wall, ensure the reliability and safety of the connection between the washing machine and the wall, and reduce noise, the existing technology generally adopts a program to control the inner drum speed. The speed is set according to the eccentricity feedback of the inner drum rotation to avoid excessive vibration and avoid excessive vibration transmitted to the wall.

[0061] However, reducing vibration transmitted to the wall can also be achieved by optimizing the vibration transmission path. This optimization can effectively reduce the vibration transmitted to the wall under the same operating conditions. Furthermore, if the vibration transmitted to the wall is the same, a washing machine with an optimized vibration transmission path can run at a higher spin speed, thereby reducing spin time and improving spin performance.

[0062] Example 1

[0063] Based on this, Figures 1-4 As shown, the damper 1 according to an embodiment of the present invention includes:

[0064] A first rod 11 having a first end A and a second end A opposite to each other. The first rod 11 has a sliding track extending in the same direction as the first rod 11 and having an opening at the first end A.

[0065] A second rod 12 having a first end B and a second end B opposite to each other, wherein the first end B of the second rod 12 passes through the opening and is slidably disposed in the sliding track;

[0066] A first connecting member 13 having a first end C and a second end C opposite to each other. The first end C of the first connecting member 13 is used to connect to the vibration generating component. The second end C of the first connecting member 13 is movably connected to the second end B of the second rod 12 with multiple degrees of freedom, so that the first connecting member 13 can rotate circumferentially relative to the axis of the second rod 12 about the second end B.

[0067] A second connecting member 14 having a first end D and a second end D opposite to each other. The first end D of the second connecting member 14 is used to connect to the vibration receiving component. The second end D of the second connecting member 14 is movably connected to the second end A of the first rod 11 with multiple degrees of freedom, so that the second connecting member 14 can rotate circumferentially relative to the axis of the first rod 11 with the second end A as the center.

[0068] a spring 15 disposed between the first connecting member 13 and the second connecting member 14;

[0069] When the first connecting member 13 and the second connecting member 14 have a movement tendency to move toward each other, the spring 15 has a thrust force to push the first connecting member 13 and the second connecting member 14 away from each other;

[0070] When the first connecting member 13 and the second connecting member 14 have a tendency to move away from each other, the spring 15 has a pulling force to pull the first connecting member 13 and the second connecting member 14 toward each other;

[0071] When the first connecting member 13 and / or the second connecting member 14 has a tendency to rotate circumferentially relative to the first rod body 11 , the spring 15 has an elastic force to drive the first connecting member 13 and / or the second connecting member 14 to return to being coaxial with the first rod body 11 .

[0072] Specifically, in the first end A, the second end A, the first end B, the second end B, the first end C, the second end C, the first end D and the second end D, these letters A, B, C, and D do not have specific meanings, but are only for distinguishing different ends and for convenience of expression.

[0073] The spring 15 can be a linear stiffness spring. The linear stiffness spring 15 can be a standard rectangular spring, a standard coil spring, etc. The coil spring can have compression elastic force, tension elastic force and torsional elastic force, which can achieve the effect of causing the second rod body 12 to translate in the sliding track and restore the first connecting member 13 and the second connecting member 14 to be coaxial with the first rod body 11. The spring 15 can achieve an energy storage effect when subjected to force.

[0074] The first rod body 11 and the second rod body 12 can be two strip-shaped members extending in a direction. The sliding track in the first rod body 11 is adapted to the second rod body 12, so that the second rod body 12 can be slidably set in the first rod body 11. The sliding track can be filled with appropriate damping oil with specific properties, which can increase the damping force so that the first rod body 11 and the second rod body 12 have a vibration reduction effect along the extension direction.

[0075] The first connecting member 13 can connect the second rod body 12 and the external component, and the second connecting member 14 can connect the first rod body 11 and another external component. After the two external components are connected through the damper 1 proposed in this application, the vibration transmitted from the first external component to the second external component can be effectively reduced.

[0076] Specifically, in the process of reducing vibration, the first connecting member 13 can be connected with the second rod body 12 in a multi-degree-of-freedom manner, and the second connecting member 14 can be connected with the first rod body 11 in a multi-degree-of-freedom manner, and the spring 15 can be used to exert an elastic force on the first connecting member 13 and the second connecting member 14, so that the damper 1 not only has a tensile and compressive vibration reduction effect, but also has a bending vibration reduction effect, a shear vibration reduction effect, and a torsional vibration reduction effect.

[0077] Among them, when playing the bending vibration reduction role, the first connecting member 13 and / or the second connecting member 14 can rotate in the same direction relative to the extension and contraction direction of the first rod body 11 and the second rod body 12, generate bending, and then recover under the action of the spring 15, thereby achieving the bending vibration reduction effect.

[0078] When playing the role of shear vibration reduction, since the damper 1 of the present application is provided with two movable connecting structures, namely the first connecting member 13 and the second connecting member 14, the first connecting member 13 can rotate circumferentially relative to the axis of the second rod body 12, and the second connecting member 14 can rotate circumferentially relative to the axial direction of the first rod body 11. When the forces on the first connecting member 13 and the second connecting member 14 are opposite, they rotate in opposite directions, generate bending, and when shear force is generated, they can recover under the action of the spring 15, thereby achieving the shear vibration reduction effect.

[0079] When playing the role of torsional vibration reduction, since the damper 1 of the present application is provided with two movable connecting structures, namely the first connecting member 13 and the second connecting member 14, wherein the first connecting member 13 can be twisted relative to the axis of the second rod body 12, and the second connecting member 14 can be twisted relative to the axis of the first rod body 11, when the first connecting member 13 and / or the second connecting member 14 are twisted, they can be restored under the action of the spring 15, thereby achieving the torsional vibration reduction effect.

[0080] The damper 1 proposed in the application has tensile and compressive vibration reduction effects, bending vibration reduction effects, shear vibration reduction effects and torsional vibration reduction effects, and can achieve better vibration reduction and support effects. The damper 1 can be applied to the vibration reduction structure 100 to connect the inner drum 3 and the outer drum 4 of the wall-mounted washing machine. When the inner drum 3 rotates and generates vibration, the vibration transmitted from the inner drum 3 to the outer drum 4 can be effectively reduced, which not only makes the connection between the outer drum 4 and the wall more stable and reliable, but also effectively reduces noise.

[0081] Moreover, when the vibration reduction structure 100 formed by the damper 1 is used to reduce vibration of the wall-mounted washing machine, the vibration transmission path is optimized, so that the inner drum 3 of the wall-mounted washing machine can reach a higher speed when dehydrating, reducing the limitation of the vibration problem, thereby making the dehydration efficiency better, the dehydration performance better, the dehydration time shorter, and improving the user experience.

[0082] According to the damper 1 of the embodiment of the present invention, the second rod 12 can be telescopically slidable in the sliding track of the first rod 11, and the first connecting member 13 is movably connected to the second rod 12 with multiple degrees of freedom, and the second connecting member 14 is movably connected to the first rod 11 with multiple degrees of freedom, so that the first connecting member 13 can rotate around the second rod 12, and the second connecting member 14 can rotate around the first rod 11, so that the damper 1 can not only have the vibration reduction and support functions along the telescopic direction, but also can have a certain load tension, compression, bending, shearing and torsion, wherein the second rod 12 is in the sliding track resistance and Tensile and compressive vibration reduction is achieved under the action of the elastic force and pressure of the spring 15. The multi-degree-of-freedom movable connection of the first connecting member 13 and the second connecting member 14 cooperates with the elastic force of the spring 15 to achieve bending vibration reduction, shear vibration reduction and torsional vibration reduction, so that the damper 1 can have a better vibration reduction effect. The vibration reduction structure 100 can be formed through the damper 1 to effectively reduce the vibration of the wall-mounted washing machine, thereby preventing the vibration generated by the wall-mounted washing machine from being transmitted to the wall. It can affect the reliability and safety of the connection between the wall-mounted washing machine and the wall without reducing the rotation speed of the inner drum 3, and can also achieve a noise reduction effect.

[0083] In some embodiments, the multi-degree-of-freedom movable connection between the second end C of the first connecting member 13 and the second end B of the second rod body 12 adopts a ball joint connection matching structure or a composite hinge connection matching structure;

[0084] The multi-degree-of-freedom movable connection between the second end D of the second connecting member 14 and the second end A of the first rod body 11 adopts a ball joint connection or a compound hinge connection.

[0085] Specifically, the multi-DOF articulation proposed above can be achieved through a ball joint. Alternatively, a composite hinge can be used instead. A composite hinge is a revolute pair consisting of three or more components on two or more coaxial axes. Using the same bearing structure as a ball joint, it offers the advantages of flexible and accurate control and a large torsion angle.

[0086] In some embodiments, a first shell 16 is sleeved around the outer periphery of the first connecting member 13 , and a second shell 17 is sleeved around the outer periphery of the second connecting member 14 ;

[0087] The spring 15 is a linear stiffness spring 15 , one end of the spring 15 along its expansion and contraction direction is connected to the first housing 16 , and the other end of the spring 15 is connected to the second housing 17 .

[0088] Specifically, the spring 15 can be a linear stiffness spring 15, which is connected to the first connecting member 13 and the second connecting member 14 through the first shell and the second shell. The spring 15 can make the first connecting member 13 and the second connecting member 14 quickly reset after rotation, thereby absorbing vibration.

[0089] In some embodiments, the sliding track of the first rod body 11 is filled with damping oil.

[0090] Specifically, the properties of the damping oil depend on the required damping force of the damper 1 .

[0091] Assembly process of spring damper 1:

[0092] First, the spring 15 is fixedly connected to the first shell and the second shell, and welding or other fixing processes can be used.

[0093] Next, the first connecting member 13 is connected to the second rod body 12 by a ball joint, and the second connecting member 14 is connected to the first rod body 11 by a ball joint.

[0094] Then, the first rod 11 of the damper 1 is passed through the hole of the second housing, and the second connecting member 14 is threadedly connected to the second housing using a wrench.

[0095] Finally, the second rod 12 is passed through the first housing and inserted into the sliding track of the first rod 11, and the first connector 13 is screwed to the first housing using a wrench. A certain amount of damping oil is filled in the sliding track.

[0096] Example 2

[0097] The embodiment of the present application further provides a vibration damping structure 100, comprising:

[0098] a plurality of the aforementioned dampers 1;

[0099] Multiple dampers 1 are arranged side by side in two groups along the axial direction, and each group of dampers 1 is arranged with multiple dampers 1 at intervals along the circumferential direction. Each damper 1 is extended radially, and the ends of each damper 1 that are close to each other are used to connect with the vibration generating component, and the ends that are away from each other are used to connect with the vibration receiving component.

[0100] Specifically, the number of dampers 1 can be 8, and the 8 dampers 1 are divided into two groups, with 4 dampers in one group. The two groups of dampers 1 are arranged side by side, and the 4 dampers 1 in each group can form a 90° angle with each other to buffer the vibrations at various locations on the outer periphery of the inner drum 3 along the circumferential direction. The spacing between the two groups of dampers 1 can be calculated and determined based on the actual maximum load condition of the wall-mounted washing machine and the thickness of the entire machine. The two groups of dampers 1 are in a parallel relationship and are not connected to each other. Through this double-row multi-degree-of-freedom vibration damping structure 100, the transmission of vibration can be effectively reduced.

[0101] In some embodiments, one of the two groups of dampers arranged side by side is a front damper assembly, and the other group is a rear damper assembly. The front dampers are used to support the vibration generating components, and the rear dampers are used to form a torque at the connection point between them and the vibration generating components.

[0102] Specifically, the front damper assembly close to the inner tube 3 can act as a fulcrum, while the rear damper assembly away from the inner tube 3 will form a torque at the fulcrum, thereby balancing the torque formed by the centrifugal force of the inner tube 3, thereby achieving stable operation of the inner tube 3 and achieving an effective vibration reduction effect.

[0103] Example 3

[0104] The present application also provides a wall-mounted washing machine, comprising:

[0105] An inner cylinder 3, an outer cylinder 4, and a vibration damping structure 100 disposed between the inner cylinder 3 and the outer cylinder 4;

[0106] A bearing seat 31 is provided at the bottom of the inner cylinder 3. One end of the bearing seat 31 along the axial direction of the inner cylinder 3 is connected to the inner cylinder 3, and the other end passes through the rear wall of the outer cylinder 4.

[0107] The vibration reduction structure 100 comprises: the aforementioned damper 1;

[0108] The vibration-damping structure 2 is disposed between the inner cylinder 3 and the outer cylinder 4. The dampers 1 of the vibration-damping structure 2 are arranged side by side in two groups along the axial direction of the outer cylinder 4. The multiple dampers 1 in each group are arranged around the inner cylinder 3 and the outer cylinder 4 along the circumferential direction of the outer cylinder 4.

[0109] Each damper 1 has one end close to the bearing seat 31 along the radial direction of the outer cylinder 4 connected to the bearing seat 31 , and one end close to the outer cylinder 4 connected to the outer cylinder 4 .

[0110] In some embodiments, a mounting seat 41 is provided on the outer periphery of the bottom of the outer cylinder 4, and the mounting seat 41 is used to connect to the external wall;

[0111] One end of the bearing seat 31 passing through the rear wall of the outer cylinder 4 is located on the inner side of the mounting seat 41;

[0112] The damper 1 is disposed between the mounting seat 41 and the bearing seat 31 . One end of the damper 1 is connected to a portion of the bearing seat 31 located inside the mounting seat 41 , and the other end is connected to the mounting seat 41 .

[0113] Specifically, the wall-mounted washing machine includes an inner drum 3 and an outer drum 4. The inner drum 3 is pivotally arranged in the outer drum 4, and the rear side of the outer drum 4 is fixed to the wall. A bearing seat 31 is provided on the rear side of the inner drum 3. The bearing seat 31 is equipped with a drive motor. The drive motor drives the inner drum 3 so that the inner drum 3 can rotate in the outer drum 4, and the bearing seat 31 passes through the rear wall of the outer drum 4.

[0114] The mounting seat 41 can be an annular mounting seat 41 surrounding the outer side of the outer tube 4, or it can be four segmented mounting seats 41 evenly arranged on the circumference of the outer tube 4, and each mounting seat 41 corresponds to a damper 1 in each group.

[0115] When setting up the vibration reduction structure 100, two groups of dampers 1 can be set between the mounting seat 41 and the bearing seat 31. Each damper 1 extends along the radial direction of the outer tube 4. One end of the damper 1 along its extension direction is connected to the mounting seat 41, and the other end is connected to the bearing seat 31. The damper 1 can absorb the vibration of the bearing seat 31, thereby preventing the mounting seat 41 from vibrating significantly along with the inner tube 3, affecting the stability of the connection between the mounting seat 41 and the wall, and reducing noise.

[0116] In some embodiments, one of the two groups of dampers arranged side by side along the axial direction of the outer cylinder 4 is a front damper assembly, and the other is a rear damper assembly. The front damper assembly is closer to the front side 3 of the inner cylinder than the rear damper assembly. The front dampers are used to support the inner cylinder 3, and the rear dampers are used to generate a torque at the connection point between them and the inner cylinder 3 to balance the torque generated by the centrifugal force when the inner cylinder 3 rotates.

[0117] Specifically, the front damper assembly close to the inner tube 3 can act as a fulcrum, while the rear damper assembly away from the inner tube 3 will form a torque at the fulcrum, thereby balancing the torque formed by the centrifugal force of the inner tube 3, thereby achieving stable operation of the inner tube 3 and achieving an effective vibration reduction effect.

[0118] In some embodiments, a rubber seal 5 is provided between the mounting seat 41 and the rear wall of the outer tube 4 to provide a flexible connection between the mounting seat 41 and the outer tube 4.

[0119] The rubber seal 5 is arranged side by side with the damper 1 and is located at the front side of the damper along the axial direction of the inner tube 3 .

[0120] Specifically, the mounting seat 41 and the rear wall of the outer cylinder 4 are flexibly connected instead of being fixedly connected through a patina process. This not only further reduces the vibration transmitted from the inner cylinder 3 to the outer cylinder 4, but also allows the rubber seal 5 to be disassembled and assembled when the internal space needs to be cleaned, which is convenient for later maintenance operations. In addition, the rubber seal 5 can also provide a certain support for the mounting seat 41.

[0121] Specifically, when a wall-mounted washing machine is in operation, the vibration of the inner drum 3 is transmitted to the outer drum 4 through the damper 1 and rubber seal 5. Due to the relatively weak rigidity of the rubber seal 5, the transmitted vibration is much lower than that of the inner drum 3. Since the outer drum 4 is connected to the wall, the vibration transmitted to the wall is significantly reduced. During the operation of the inner drum 3, as the rotation speed increases, the centrifugal force generated by the eccentricity increases, and the damping force of the damper 1 also increases with the increase in rotation speed, thereby achieving torque balance. Because the damper 1 is an energy-absorbing element, it dissipates some of the vibration energy of the inner drum 3, reducing the energy transmitted to the wall and thus achieving vibration reduction.

[0122] In some embodiments, a pre-tightening screw 2 is screwed onto the mounting seat 41 along the radial direction of the outer cylinder 4 , and the pre-tightening screw 2 passes through the mounting seat 41 and is connected to the damper 1 .

[0123] In some embodiments, the preload force of the spring 15 of the damper 1 is greater than the gravity of the inner cylinder 3 under a fully loaded static working condition.

[0124] Specifically, by adopting the pre-tightening screw 2, the spring 15 of the damper 1 can be stretched, thereby realizing pre-tightening of the damper 1, which can ensure that the displacement of the damper 1 is small or even no deformation under the action of gravity of the inner cylinder 3. When the gravity load of the inner cylinder 3 is greater than the pre-tightening load of the spring 15, the spring 15 deforms, and the six-degree-of-freedom damper 1 is always in a stretched state within the rated static load condition of the inner cylinder 3, which can ensure the stability of the vibration reduction performance.
