[0051] Hereinafter, the exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0052] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order described or illustrated, unless explicitly stated as the order of performance. It should also be understood that additional or alternative steps may be used.

[0053] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first", "second", and other numerical terms when used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0054] For ease of description, spatial relative relationship terms may be used herein to describe the relationship of one element or feature shown in the figures to another element or feature, such as "inner", "outer", "inside", "outside", "below", "beneath", "above", "over", etc. Such spatial relative relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "beneath" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the example term "below" can include both an orientation above and below. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are to be interpreted accordingly.

[0055] As Figures 1 to 7 shown, according to an embodiment of the present application, a drive mechanism 40 for a laundry treatment device 100 is provided, and the drive mechanism 40 includes a motor assembly 41 and a vibration damping assembly 42.

[0056] Specifically, the motor assembly 41 includes a rotating shaft 416 and a housing 411. The rotating shaft 416 passes through the housing 411 and can rotate relative to the housing 411. At least one of the rotating shaft 416 and the housing 411 is mounted on the base 11 of the laundry treating apparatus 100 through a vibration damping assembly 42. Among them, the vibration damping assembly 42 can at least elastically deform in the radial direction of the rotating shaft 416.

[0057] It should be understood that the elastic deformation of the vibration damping assembly 42 in the radial direction of the rotating shaft 416 means that the vibration damping assembly 42 can generate deformation under the action of an external force in the axial direction of the rotating shaft 416, and this deformation is an elastic deformation. When the external force decreases or disappears, the elastic deformation can recover.

[0058] In this application, the vibration damping assembly 42 is connected to at least one of the housing 411 and the rotating shaft 416 of the motor assembly 41. When the motor assembly 41 is running, the motor assembly 41 will generate displacement in the radial direction of the rotating shaft 416, and vibration will be generated due to the displacement, thereby generating vibration noise. The motor assembly 41 is arranged to be connected to the base 11 through the vibration damping assembly 42. When the motor assembly 41 vibrates during operation, the displacement generated by the vibration is absorbed by the vibration damping assembly 42, thereby reducing the possibility of transmission to the base 11, and further reducing the generation of vibration noise, so that the possibility of generating the resonance frequency is reduced.

[0059] During the operation of the drive mechanism 40, the rotating shaft 416 rotates relative to the housing 411. By connecting at least one of the rotating shaft 416 and the housing 411 to the base 11 through the vibration damping assembly 42, the vibration generated by the motor assembly 41 in the radial direction of the rotating shaft 416 is at least reduced by the vibration damping assembly 42, thereby reducing the vibration transmitted from the motor assembly 41 to the base 11 during operation, and further reducing the generation of vibration noise and resonance frequency.

[0060] It should be noted that in this application, the vibration damping assembly 42 can absorb the vibration generated by the motor assembly 41 through elastic deformation. Among them, during the operation of the motor assembly 41, the vibration damping assembly 42 can not only absorb the displacement generated by the motor assembly 41 in the radial direction along the rotating shaft 416, but also absorb the displacement generated by the motor assembly 41 in other directions, thereby blocking the vibration generated by the motor assembly 41 during operation, so as to reduce the situation that the motor assembly 41 transmits the vibration to the base 11, which in turn causes the entire laundry treating apparatus 100 to vibrate and generate vibration noise, effectively improving the comfort of the user during use.

[0061] In the present application, the motor assembly 41 further includes a rotor 414 and a stator. The stator is disposed in the housing 411, the rotor 414 is disposed on the rotating shaft 416, and there is a gap between the rotor 414 and the stator. When the motor assembly 41 is operating, the stator generates a magnetic torque on the rotor 414. Driven by the magnetic torque, the rotor 414 drives the rotating shaft 416 to rotate, so as to output power by using the rotation of the rotating shaft 416.

[0062] In addition, in the present application, the motor assembly 41 further includes a first wheel 412 and a second wheel 419. The first wheel 412 is disposed outside the housing 411 and sleeved on the rotating shaft 416. The second wheel 419 is rotatably disposed on the housing 411 and is in transmission connection with the drum assembly 20. The first wheel 412 and the second wheel 419 are in transmission connection through a transmission member. Among them, the diameter of the first wheel 412 is smaller than the diameter of the second wheel 419. By providing the first wheel 412 and the second wheel 419, the speed reduction of the motor assembly 41 is realized, so that the rotational speed output by the motor assembly 41 can meet the driving requirements of the drum assembly 20, and then the drum assembly 20 is effectively utilized to process clothes.

[0063] In addition, the first wheel 412 and the second wheel 419 can both be sprockets. In this case, the transmission member is a transmission chain. The first wheel 412 and the second wheel 419 can both be belt pulleys. In this case, the transmission member is a transmission belt.

[0064] In some embodiments of the present application, as Figures 2 to 4 shown, in the motor assembly 41, there is also a first bearing 418. The first bearing 418 includes an inner ring and an outer ring arranged coaxially. There are a plurality of rolling elements between the outer ring and the inner ring, and the outer ring and the inner ring can rotate relative to each other. In the vibration damping assembly 42, there is also a first vibration damping ring 421. Among them, the inner ring is sleeved on the rotating shaft 416, and the first vibration damping ring 421 is sleeved on the outer ring.

[0065] Specifically, when the driving mechanism 40 is used for the clothes processing device 100, the rotating shaft 416 is installed on the base 11 of the cabinet 10 of the clothes processing device 100 through the first bearing 418 and the first vibration damping ring 421. Among them, the first vibration damping ring 421 is fixed relative to the base 11, and the rotating shaft 416 can rotate relative to the base 11. When the motor assembly 41 is operating, the rotating shaft 416 rotates. During the rotation of the rotating shaft 416, if a displacement occurs in the radial direction of the rotating shaft 416, the displacement is transmitted to the first vibration damping ring 421 through the bearing. The first vibration damping ring absorbs the displacement by elastic deformation, thereby reducing the transmission of vibration to the base 11, and further reducing the generation of noise caused by vibration, achieving the purpose of vibration damping and noise reduction.

[0066] It should be understood that along the axial direction of the rotating shaft 416, the lengths of the inner ring and the outer ring are equal. At the same time, along the axial direction of the rotating shaft 416, the length of the first damping ring 421 is greater than or equal to the length of the outer ring. By setting the first damping ring 421, the contact area between the first damping ring 421 and the first bearing 418 can be increased, so as to effectively reduce the axial vibration of the rotating shaft 416, and further reduce the vibration noise during the use of the driving mechanism 40.

[0067] In the present application, after the inner ring is sleeved on the rotating shaft 416, the inner ring and the rotating shaft 416 are fixedly connected. This fixed connection can be achieved by interference fit or by key fit.

[0068] At the same time, after the first damping ring 421 is sleeved and fitted with the outer ring, the outer ring and the first damping ring 421 are fixedly connected. This fixed connection can be achieved by interference fit or by key fit.

[0069] It should be noted that in the present application, the first damping ring 421 has a certain elastic deformation ability. Among them, the first damping ring 421 has a certain elastic deformation ability in the radial direction of the rotating shaft 416, and at the same time, the first damping ring 421 also has a certain elastic deformation ability in the axial direction of the rotating shaft 416. Therefore, when the rotating shaft 416 generates displacement in its radial or axial direction, the first damping ring 421 can absorb the displacement generated by the rotating shaft 416 through its own elastic deformation, so as to reduce the transmission of vibration during the rotation of the rotating shaft 416, thereby effectively reducing the vibration noise during the operation of the driving mechanism 40 and effectively improving the user experience.

[0070] In addition, the first damping ring 421 is a non-metallic material part. Among them, the first damping ring 421 can specifically be a plastic part or a nylon part, etc.

[0071] In some embodiments of the present application, the first damping ring 421 is a plastic part. Setting the first damping ring 421 as a plastic part is convenient for processing and improves the processing efficiency. At the same time, setting the first damping ring 421 as a plastic part, the cost of the plastic part is relatively low, which can effectively reduce the overall manufacturing cost of the driving mechanism 40.

[0072] In some embodiments of the present application, such as Figures 2 to 4 , and Figure 6 shown, in the damping assembly 42 of the present application, there is also a second damping ring 422 sleeved on the first damping ring 421. When the driving mechanism 40 is used for the laundry treatment device 100, the second damping ring 422 is connected to the base 11 of the cabinet 10 of the laundry treatment device 100.

[0073] Specifically, the second vibration damping ring 422 is coaxially sleeved outside the first vibration damping ring 421. When the driving mechanism 40 is used for the laundry treatment device 100, the second vibration damping ring 422 is installed on the base 11 of the cabinet 10 of the laundry treatment device 100. Among them, both the first vibration damping ring 421 and the second vibration damping ring are fixed relative to the base 11, and the rotating shaft 416 can rotate relative to the base 11.

[0074] When the motor assembly 41 operates, the rotating shaft 416 rotates. During the rotation of the rotating shaft 416, if a displacement occurs in the radial direction of the rotating shaft 416, the displacement is transmitted to the first vibration damping ring 421 through the bearing. The first vibration damping ring absorbs the displacement by undergoing elastic deformation. The vibration that cannot be absorbed by the first vibration damping ring is transmitted to the second vibration damping ring 422, and the second vibration damping ring 422 absorbs the displacement by undergoing elastic deformation. By using the double-layer structure formed by the first vibration damping ring 421 and the second vibration damping ring 422, the situation of vibration being transmitted to the base 11 is further reduced, and thus the situation of vibration generating noise is reduced, achieving the purpose of vibration reduction and noise reduction.

[0075] It should be understood that along the axial direction of the rotating shaft 416, the length of the second vibration damping ring 422 is greater than or equal to the length of the second vibration damping ring 422. By setting the first vibration damping ring 421 and the second vibration damping ring 422, the contact area between the first vibration damping ring 421 and the second vibration damping ring 422 is increased, so as to effectively reduce the axial vibration of the rotating shaft 416, and further reduce the vibration noise of the driving mechanism 40 during use.

[0076] In this application, after the first vibration damping ring 421 is sleeved with the first vibration damping ring 421, the first vibration damping ring 421 and the first vibration damping ring 421 are fixedly connected. The way of this fixed connection can be achieved by interference fit, or can also be achieved by bonding or welding.

[0077] It should be noted that in this application, the second vibration damping ring 422 has a certain elastic deformation ability. Among them, the second vibration damping ring 422 has a certain elastic deformation ability in the radial direction of the rotating shaft 416, and at the same time the second vibration damping ring 422 also has a certain elastic deformation ability in the axial direction of the rotating shaft 416. Therefore, when a displacement occurs in the radial or axial direction of the rotating shaft 416, the second vibration damping ring 422 can absorb the displacement generated by the rotating shaft 416 through its own elastic deformation, so as to reduce the transmission of vibration during the rotation of the rotating shaft 416, and thus effectively reduce the vibration noise during the operation of the driving mechanism 40, effectively improving the user experience.

[0078] In addition, in this application, the second vibration damping ring 422 is a non-metallic material part. Among them, the second vibration damping ring 422 can specifically be a rubber part or a silicone part.

[0079] In addition, a first support structure 111 is provided on the base 11 of the box body 10. A first installation space is provided on the first support structure 111 (such as a first support seat or a first support frame, etc.). Opposite ends of the first installation space are open structures. The second damping ring 422 is received and installed in the first installation space (the first damping ring 421, the first bearing 418, and the rotating shaft 416 are not in contact with the first support structure 111). The rotating shaft 416 extends to the outside of the first installation space through the opening of the first installation space. The first support structure 111 can limit the axial and radial directions of the second damping ring 422, so that the second damping ring 422 is fixed in the first installation space, thereby realizing the connection and fixation between the second damping ring 422 and the base 11.

[0080] In some embodiments of the present application, the second damping ring 422 is a rubber part. By setting the second damping ring 422 as a rubber part, the rubber part has better elastic deformation performance, can effectively absorb the displacement of the rotating shaft 416 through its own elastic deformation, and improves the damping and noise reduction effect. In addition, the rubber part is easy to process, improves the processing efficiency, and at the same time, the cost of the rubber part is low, which can effectively reduce the overall manufacturing cost of the drive mechanism 40.

[0081] It should be noted that in order to make the second damping ring 422, which is a rubber part, have a certain rigidity, auxiliary support components such as elastic steel sheets can be provided inside the rubber part.

[0082] In some embodiments of the present application, as Figure 4 and Figure 6 shown, a first matching structure 4211 is provided on the first damping ring 421. The first matching structure 4211 is provided on the outer peripheral surface of the first damping ring 421. A second matching structure 4221 is provided on the second damping ring 422. The second matching structure 4221 is provided on the inner peripheral surface of the second damping ring 422.

[0083] Specifically, when the second damping ring 422 cooperates with the first damping ring 421, the second damping ring 422 is sleeved on the radial outside of the first damping ring 421. The first matching structure 4211 and the second matching structure 4221 cooperate with each other and are in a concave-convex fit. The outer peripheral surface of the first damping ring 421 abuts against the inner peripheral surface of the second damping ring 422 to realize the connection and fixation between the first damping ring 421 and the second damping ring 422.

[0084] By providing the first matching structure 4211 and the second matching structure 4221 that are in concave-convex fit with each other, the contact area between the first damping ring 421 and the second damping ring 422 can be increased, so that the second damping ring 422 can be fully utilized to absorb vibration, and further, the vibration of the drive mechanism 40 in the axial direction of the rotating shaft 416 can be reduced, so that the damping and noise reduction effect can be further improved.

[0085] In addition, after the concave-convex fit between the first mating structure 4211 and the second mating structure 4221, at least in the circumferential direction of the rotating shaft 416, the first damping ring 421 and the second damping ring 422 can be limited, so that the second damping ring 422 is effectively sleeved on the first damping ring 421, and the combined structure formed by the second damping ring 422 and the second damping ring 422 is used to absorb vibration, so that the effect of vibration reduction and noise reduction is effectively improved.

[0086] It should be noted that the first mating structure 4211 and the second mating structure 4221 are in a concave-convex fit, wherein one of the first mating structure 4211 and the second mating structure 4221 is a convex structure and the other is a concave structure, and the convex structure is embedded in the concave structure to achieve the concave-convex fit between the first mating structure 4211 and the second mating structure 4221.

[0087] In addition, the convex structure can be a convex bump or a convex block structure, and the concave structure can be a concave pit or a concave groove structure.

[0088] In some embodiments of the present application, one of the first mating structure 4211 and the second mating structure 4221 is a groove (such as a rectangular groove or a C-shaped groove), and the other of the first mating structure 4211 and the second mating structure 4221 is a convex block (the shape of the convex block is adapted to the shape of the groove).

[0089] For example, the first mating structure 4211 is a groove provided on the outer peripheral surface of the first damping ring 421, wherein the groove penetrates through opposite ends of the first damping ring 421 in the axial direction of the rotating shaft 416, and the second mating structure 4221 is a convex block provided on the inner peripheral surface of the second damping ring 422. When the first damping ring 421 and the second damping ring 422 are assembled, the second damping ring 422 is coaxially arranged at one end of the first damping ring 421, so that the convex block and the groove are correspondingly arranged, and the second damping ring 422 is driven to be sleeved on the first damping ring 421 in the axial direction of the rotating shaft 416, so that the convex block enters the groove from one end of the groove. The structure of the groove and the convex ring is provided to facilitate the assembly between the second damping ring 422 and the first damping ring 421.

[0090] It should be noted that the groove formed on the outer peripheral surface of the first damping ring 421 can be manufactured by integral machining with the first damping ring 421, or can be formed by machining and opening on the outer surface of the first damping ring 421. At the same time, the convex block formed on the inner peripheral surface of the second damping ring 422 can be manufactured by integral machining with the second damping ring 422, or can be fixed on the inner peripheral surface of the second damping ring 422 by bonding or welding after being separately machined.

[0091] For another example, the second mating structure 4221 is a groove provided on the outer peripheral surface of the second damping ring 422. The groove penetrates through opposite ends of the second damping ring 422 in the axial direction of the rotating shaft 416. The first mating structure 4211 is a protrusion provided on the inner peripheral surface of the first damping ring 421. When assembling the first damping ring 421 and the second damping ring 422, the second damping ring 422 is coaxially arranged at one end of the first damping ring 421, such that the protrusion and the groove are correspondingly arranged. The second damping ring 422 is driven in the axial direction of the rotating shaft 416 to be sleeved on the first damping ring 421, so that the protrusion enters the groove from one end of the groove. The structure of the groove and the protrusion facilitates the assembly between the second damping ring 422 and the first damping ring 421.

[0092] It should be noted that the groove formed on the outer peripheral surface of the second damping ring 422 can be manufactured by integral machining with the second damping ring 422, or can be formed by machining on the outer surface of the second damping ring 422. At the same time, the protrusion formed on the inner peripheral surface of the first damping ring 421 can be manufactured by integral machining with the first damping ring 421, or can be fixed on the inner peripheral surface of the first damping ring 421 by bonding or welding after being separately machined.

[0093] In some embodiments of the present application, such as Figure 4 and Figure 6 shown, the number of the first mating structures 4211 is set to be multiple, the number of the second mating structures 4221 is also set to be multiple, and the number of the second mating structures 4221 is equal to the number of the first mating structures 4211.

[0094] Specifically, along the circumferential direction of the first damping ring 421, the multiple first mating structures 4211 are arranged at intervals. Along the axial direction of the second damping ring 422, the multiple second mating structures 4221 are arranged at intervals. Among them, the second mating structures 4221 and the first mating structures 4211 are arranged in one-to-one correspondence.

[0095] By providing multiple first mating structures 4211 and multiple second mating structures 4221, the contact area between the first damping ring 421 and the second damping ring 422 can be further increased, so that the vibration between the first damping ring 421 and the second damping ring 422 can be effectively transmitted to absorb the vibration in the axial direction of the rotating shaft 416, thereby further improving the vibration reduction and noise reduction effect and effectively enhancing the user experience.

[0096] It should be noted that the interval mode of the first mating structures 4211 along the circumferential direction of the first damping ring 421 can be equally spaced or non-equally spaced.

[0097] In some embodiments of the present application, such asFigures 1 to 4 As shown, in the housing 411 of the motor assembly 41, there is an end cover 4111, and the rotating shaft 416 passes through the end cover 4111 and is arranged outside. In the damping assembly 42, there is also a damping member 423. When the driving mechanism 40 is used for the laundry treatment device 100, the base 11 is connected to the end cover 4111 through the damping member 423.

[0098] Specifically, in the present application, the first damping ring 421 and the second damping ring 422 form a first damping structure, which is connected to the rotating shaft 416 of the motor assembly 41 through the first bearing 418. The damping member 423 is connected to the end cover 4111 of the housing 411 and forms a second damping structure. Among them, the first damping structure and the second damping structure are arranged at intervals along the axial direction of the rotating shaft 416. The first damping structure absorbs the vibration of the rotating shaft 416 to reduce the vibration of the rotating shaft 416, and the second damping structure absorbs the vibration of the housing 411 to reduce the vibration of the housing 411.

[0099] By arranging the damping member 423, the vibration and noise reduction of the motor assembly 41 can be carried out at multiple positions, and further the effect of vibration and noise reduction can be improved, so that the user experience is effectively improved.

[0100] It should be noted that in the present application, the damping member 423 has a certain elastic deformation ability. The end cover 4111 is connected to the base 11 through the damping member 423. The damping member 423 has a certain elastic deformation ability in the radial direction of the rotating shaft 416, and at the same time, the damping member 423 also has a certain elastic deformation ability in the axial direction of the rotating shaft 416. Therefore, when the housing 411 generates displacement in the radial or axial direction of the rotating shaft 416, the damping member 423 can absorb the displacement generated by the rotating shaft 416 through its own elastic deformation to reduce the transmission of the vibration during the rotation of the rotating shaft 416, thereby effectively reducing the vibration noise during the operation of the driving mechanism 40, and effectively improving the user experience.

[0101] In addition, in the present application, as Figure 4As shown in the figure, the motor assembly 41 further includes a second bearing 413 and a third bearing 415. The housing 411 further includes a housing body and a rear cover 417. The housing body has two openings arranged oppositely along the axial direction of the rotating shaft 416. The end cover 4111 is connected to the housing body and closes one opening, and the rear cover 417 is connected to the housing body and closes the other opening. Opposite ends of the rotating shaft 416 respectively pass through the end cover 4111 and the rear cover 417. One end passing through the rear cover 417 is sleeved with a first bearing 418 and is connected to the base 11 through a first damping ring 421 and a second damping ring 422. One end passing through the end cover 4111 is installed with a first wheel 412. The second bearing 413 is installed on the end cover 4111, and the rotating shaft 416 passes through the second bearing 413. The third bearing 415 is installed on the rear cover 417, and the rotating shaft 416 passes through the third bearing 415.

[0102] In addition, the end cover 4111, the housing body and the rear cover 417 can be fixedly connected by bonding, welding or fasteners (such as bolts, etc.).

[0103] In some embodiments of the present application, as Figures 1 to 4 shown, the damping member 423 is arranged as a ring structure, and this ring structure is sleeved on the sleeved structure of the end cover 4111.

[0104] Specifically, the sleeved structure is arranged on the end cover 4111 and is arranged around the axial direction of the rotating shaft 416, and the sleeved structure is coaxially arranged with the rotating shaft 416. The damping structure of the ring structure is sleeved on the sleeved structure, which can make the circumferential direction of the end cover 4111 fully contact with the damping member 423. Thus, the vibration generated by the housing 411 can be absorbed by the damping member 423, and further the effect of damping and noise reduction of the electrode assembly can be improved.

[0105] It should be noted that in the present application, the sleeved structure can be an annular groove opened on the end cover 4111 or an annular rib formed on the end cover 4111.

[0106] In addition, a second support structure 112 is provided on the base 11 of the box body 10. A second installation space is provided on the second support structure 112 (such as a second support seat or a second support frame, etc.). Opposite ends of the second installation space are open structures. The damping member 423 in the shape of a ring structure is received and installed in the second installation space (the end cover 4111 and the rotating shaft 416 do not contact the second support structure 112). The rotating shaft 416 extends to the outside of the second installation space through the opening of the second installation space. The second support structure 112 can limit the axial and radial directions of the damping member 423 in the shape of a ring structure, so that the damping member 423 in the shape of a ring structure is fixed in the second installation space, thereby realizing the connection and fixation of the damping member 423 and the base 11.

[0107] In some embodiments of the present application, the vibration damping member 423 is a rubber member. By setting the vibration damping member 423 as a rubber member, the rubber member has better elastic deformation performance and can effectively absorb the displacement of the housing 411 through its own elastic deformation, improving the vibration damping and noise reduction effect. In addition, the rubber member is easy to process, improving the processing efficiency. At the same time, the cost of the rubber member is low, which can effectively reduce the overall manufacturing cost of the drive mechanism 40.

[0108] It should be noted that in order to endow the vibration damping member 423, which is a rubber member, with certain rigidity, auxiliary support components such as elastic steel sheets can be arranged inside the rubber member.

[0109] In some embodiments of the present application, as Figure 1 , Figure 2 and up to Figure 5 shown, the motor assembly 41 further includes an electrical connection device 43 installed on the end cover 4111. Among them, the electrical connection device 43 is installed on the connection structure of the end cover 4111. By installing the electrical connection device 43 on the end cover 4111, it is convenient for the installation of the electrical connection device 43, thereby improving the assembly efficiency and the reliability of installation and fixation.

[0110] In addition, by installing the electrical connection device 43 on the end cover 4111, it is convenient for wiring the motor assembly 41 and fixing components such as wire materials, thereby reducing the vibration caused by the scattering of wire materials.

[0111] It should be noted that the connection structure is arranged on the end cover 4111 and can be a connection hole. The electrical connection device 43 passes through the connection hole with components such as bolts to connect and fix the electrical connection piece to the end cover 4111.

[0112] As Figures 1 to 7 shown, a second aspect of the present invention also proposes a laundry treatment device 100.

[0113] According to the laundry treatment device 100 of the present application, at least one of the rotating shaft 416 and the housing 411 of the motor assembly 41 is connected to the base 11 of the laundry treatment device 100. During the operation of the drive mechanism 40, the rotating shaft 416 rotates. By connecting at least one of the rotating shaft 416 and the housing 411 to the base 11 through the vibration damping assembly 42, at least the vibration generated by the motor assembly 41 in the radial direction of the rotating shaft 416 is reduced by the vibration damping assembly 42, reducing the vibration transmitted from the motor assembly 41 to the base 11 during operation, thereby reducing the generation of vibration noise and resonance frequency.

[0114] In addition, a feeding port is provided on the cabinet 10. The feeding port is communicated with the laundry treatment cavity in the drum assembly 20. A door body 30 is provided on the cabinet 10, and the feeding port is opened or closed by using the door body 30.

[0115] In addition, the drum assembly 20 includes an outer drum 21 and an inner drum 22. The inner drum 22 is rotatably arranged in the outer drum 21. The inside of the inner drum 22 is a laundry treatment cavity for treating laundry. The rotating shaft of the motor assembly 41 is in transmission connection with the inner drum 22 of the drum assembly 20 through a belt pulley and a transmission belt 50 to drive the inner drum 22 to rotate in the outer drum 21.

[0116] In this application, the above-mentioned laundry treatment device can be an all-in-one washing and drying machine, a washing machine and / or a dryer. For the convenience of description, the attached drawings of the specification of this application only take the laundry treatment device as an example of a dryer with a drying function for illustration.
