Description

Technical Field

[0001] This utility model relates to the field of washing machines, and in particular to a support suspension device and a washing machine including the same. Background Technology

[0002] In traditional washing machines, the outer drum is connected to the casing via suspension springs and vibration dampers. The suspension springs act as elastic elements to isolate vibrations, while the vibration dampers primarily function as damping elements to attenuate vibrations. The combination of vibration dampers and suspension springs plays a significant role in isolating vibrations from the outer drum to the casing, while also reducing and attenuating the vibration amplitude of the outer drum. It is a core component of the washing machine.

[0003] However, the operating conditions of washing machines vary greatly at different stages of operation, and traditional suspension systems have the following problems:

[0004] 1) Suspension springs and vibration dampers are generally distributed at the upper and lower ends of the cylinder and connected to the housing. Overall, the structure is not compact enough, occupies a large amount of internal space in the housing, and affects the arrangement of other components. At the same time, in traditional suspension systems, vibration isolation and vibration damping each require a component to achieve the function (suspension spring and vibration damper), resulting in a large number of components and complexity.

[0005] 2) Traditional suspension systems, especially those that make up the shock absorbers, have many components, and both ends are connected to the cylinder and box body by pins. The relative movement between the connecting parts under dehydration conditions will generate structural noise, which is not conducive to the noise reduction of the whole machine. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology system, which has a complex structure and is not conducive to noise reduction of the whole machine, and to provide a support suspension device and a washing machine containing the same.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] A support and suspension device for suspending the drum of a washing machine from the casing of the washing machine, the support and suspension device comprising:

[0009] A first bracket, the first end of which is used to connect to the housing;

[0010] The second bracket, the first end of which is used to connect to the cylinder;

[0011] An elastic support assembly, made of elastic material, is a ring-shaped structure comprising, in sequence along the circumferential direction, an upper vibration isolation support, a left vibration isolation support, a lower vibration isolation support, and a right vibration isolation support. The upper vibration isolation support is used to connect to the second end of the second bracket, and the lower vibration isolation support is used to connect to the second end of the first bracket. The left and right vibration isolation supports extend vertically and are respectively connected between the upper and lower vibration isolation supports.

[0012] A rigid frame, the rigid frame being made of a rigid material, is embedded in the upper vibration isolation support and / or the lower vibration isolation support;

[0013] The upper vibration isolation support is configured to move closer to or further away from the lower vibration isolation support in the left-right direction as the weight of the cylinder changes.

[0014] In this design, the elastic support assembly includes an upper vibration-damping support, a left vibration-damping support, a lower vibration-damping support, and a right vibration-damping support, all made of elastic material and forming a ring structure. This arrangement helps reduce vibrations transmitted from the drum to the housing. The left and right vibration-damping supports enable variations in stiffness in the vertical or horizontal direction. When the drum is under heavy load, such as during washing, the left and right vibration-damping supports exhibit greater compression and stiffness in the vertical or horizontal direction, ensuring reliable load-bearing. When the drum is under light load, such as during spin-drying, the compression and stiffness of the first vibration-damping support decrease, improving the vibration isolation rate. In other words, this suspension support device provides good support stiffness in the vertical or horizontal direction, preventing the instability and deformation problems associated with compression suspensions. In addition, the lower vibration isolation support can move in the left and right directions relative to the upper vibration isolation support, thereby achieving stiffness changes in the left and right directions. It can achieve a high level of load-bearing capacity in the height or vertical direction, while achieving a smaller stiffness in the lateral or left and right directions, which is beneficial to improving the vibration isolation rate.

[0015] Furthermore, this suspension support device achieves good vibration isolation and damping effects through its upper, left, lower, and right vibration isolation supports, reducing the number of components and eliminating the traditional method of suspension with dampers and springs. This results in a more compact structure and significantly reduces the space occupied by the enclosure. Additionally, it avoids the relative movement of traditional rigidly connected structural components, thus preventing structural noise generated during component operation.

[0016] The rigid frame helps improve the reliability of the support suspension device. Furthermore, the upper and / or lower vibration isolation support parts with rigid frames do not require a large number of connection structures, which facilitates the realization of elastic support components and can further reduce the number of parts and further simplify the structure.

[0017] Preferably, the upper vibration isolation support portion and / or the top of the lower vibration isolation support portion are provided with mounting grooves, and the rigid frame is embedded in the mounting grooves;

[0018] The top surface of the rigid frame is aligned with the top surface of the corresponding upper vibration isolation support and / or the lower vibration isolation support.

[0019] In this solution, the rigid frame is installed in the mounting groove of the upper vibration isolation support and / or the lower vibration isolation support, which is convenient for installation and does not occupy additional space outside the upper vibration isolation support and / or the lower vibration isolation support, thus reducing the space occupied by the support suspension device.

[0020] Preferably, the rigid frame has multiple protruding engaging portions on both sides along the extending direction, and the mounting groove is correspondingly provided with multiple slot units; wherein, the multiple protruding engaging portions and the multiple slot units are engaged one-to-one.

[0021] And / or, the rigid frame is bonded to the upper vibration isolation support and / or the lower vibration isolation support and / or combined through a vulcanization process.

[0022] In this solution, the cooperation of multiple protruding engaging parts and multiple slot units allows the rigid frame to have more contact positions and connection surfaces with the upper vibration isolation support and / or the lower vibration isolation support, thus having a larger contact area, which is beneficial to improving the reliability of the connection between the rigid frame and the upper vibration isolation support and / or the lower vibration isolation support.

[0023] Preferably, both the left vibration isolation support and the right vibration isolation support have a bent portion along the extending direction, and the bent portion on either the left vibration isolation support or the right vibration isolation support is bent toward the other of the left vibration isolation support or the right vibration isolation support.

[0024] In this design, the bending section is more conducive to the elastic deformation of the left and right vibration isolation supports, improving the deformation capacity and further ensuring the load-bearing effect.

[0025] Preferably, for either the left vibration isolation support or the right vibration isolation support, the thickness at the bend is greater than the thickness of the rest.

[0026] In this design, the above-mentioned structural configuration is adopted, and the thickness of the bending section is set to be relatively large, which is beneficial to increase the stiffness when deforming in the height direction or vertical direction, thereby further improving the load-bearing capacity.

[0027] Preferably, for either the left vibration isolation support or the right vibration isolation support, the thickness decreases from the bent portion to the end near the upper vibration isolation support.

[0028] And / or, for either the left vibration isolation support or the right vibration isolation support, the thickness decreases from the bent portion to the end near the lower vibration isolation support.

[0029] In this solution, the above-mentioned structural method can significantly reduce material consumption while ensuring the overall load-bearing capacity, which is conducive to reducing costs.

[0030] Preferably, in the front-rear direction, the two ends of the lower vibration isolation support extend beyond the two ends of the upper vibration isolation support; and / or, the upper vibration isolation support, the left vibration isolation support, the lower vibration isolation support, and the right vibration isolation support are integrally formed.

[0031] In this design, the aforementioned structural arrangement extends from both ends of the lower vibration isolation support to the two ends of the upper vibration isolation support. This allows for a larger contact area between the lower vibration isolation support and the first bracket, improving connection reliability. Furthermore, the portion of the lower vibration isolation support extending into the upper vibration isolation support can serve as a carrier for the connection structure used to connect with the first bracket, facilitating installation. The one-piece molding design simplifies the structure of the support suspension device and reduces its space requirements. Additionally, the one-piece molded component is generally less prone to damage or breakage into parts under the significant weight of the cylinder, ensuring the overall reliability of the support suspension device.

[0032] Preferably, the first end of the first bracket is used to connect to the inner wall of the box, and the second end of the first bracket is attached to and connected to the side of the lower vibration isolation support that is away from the upper vibration isolation support.

[0033] And / or, the first end of the second bracket is used to connect to the outer wall of the cylinder, and the second end of the second bracket is attached to and connected to the side of the upper vibration isolation support that is away from the lower vibration isolation support.

[0034] In this solution, the above-mentioned structural configuration is adopted. The first bracket is attached to the lower vibration isolation support, and the contact area between the two is relatively large, thereby achieving a more reliable connection. The second bracket is attached to the upper vibration isolation support, and the contact area between the two is relatively large, thereby achieving a more reliable connection.

[0035] Preferably, an upper rigid frame is installed on the upper vibration isolation support, and a lower rigid frame is installed on the lower vibration isolation support;

[0036] The second end of the first bracket, the lower rigid frame, and the lower vibration isolation support are all provided with a plurality of first connection holes. The first bracket and the lower rigid frame are detachably connected by a plurality of first threaded fasteners passing through the plurality of first connection holes.

[0037] The second end of the second bracket, the upper rigid frame, and the upper vibration isolation support are all provided with multiple second connection holes. The second bracket and the upper rigid frame are detachably connected by multiple second threaded fasteners passing through the multiple second connection holes.

[0038] The horizontal projections of the plurality of first connecting holes are located outside the horizontal projections of the plurality of second connecting holes.

[0039] In this design, the first connecting hole is used to connect the lower vibration isolation support to the housing, and the second connecting hole is used to connect the upper vibration isolation support to the cylinder. The connection point between the upper vibration isolation support and the cylinder is located above the connection point between the lower vibration isolation support and the housing. The horizontal projections of the multiple first connecting holes are positioned outside the horizontal projections of the multiple second connecting holes, effectively placing the first connecting holes outside the second connecting holes. This staggered arrangement of the first and second connecting holes provides ample operating space for installing the first threaded fastener, facilitating the installation of the second threaded fastener. Furthermore, the lower rigid frame serves as the mounting carrier for the first connecting holes, and the upper rigid frame serves as the mounting carrier for the second connecting holes, ensuring convenient operation and guaranteeing the load-bearing and vibration isolation capabilities of the elastic support assembly.

[0040] This utility model also provides a washing machine, which includes a cabinet, a drum and the above-mentioned support and suspension device;

[0041] There are multiple cylindrical bodies, each of which is suspended from the box body by the support and suspension device; or,

[0042] There are multiple cylinders, and adjacent cylinders are connected to each other. The two cylinders at both ends are suspended from the box body by the support and suspension device.

[0043] In this scheme, depending on the actual layout requirements, each of the multiple cylinders can be connected to the box via a suspension device, or only the cylinders at both ends can be connected to the box via a suspension device. The layout is flexible, as long as the reliable suspension of the cylinders can be guaranteed.

[0044] The positive and progressive effects of this utility model are as follows:

[0045] In this application, the elastic support assembly includes an upper vibration isolation support, a left vibration isolation support, a lower vibration isolation support, and a right vibration isolation support, all made of elastic material and forming a ring structure. This arrangement helps to reduce vibrations transmitted from the drum to the housing. The left and right vibration isolation supports enable variations in stiffness in the height or vertical direction. When the drum load is high, such as during washing, the left and right vibration isolation supports exhibit greater compression and stiffness in the height or vertical direction, ensuring reliable load-bearing. When the drum load is low, such as during spin-drying, the compression and stiffness of the first vibration isolation support decrease in the height or vertical direction, improving the vibration isolation rate. In other words, this suspension support device provides good support stiffness in the height or vertical direction, avoiding the problem of instability and deformation in compression-type suspensions. In addition, the lower vibration isolation support can move in the left and right directions relative to the upper vibration isolation support, thereby achieving stiffness changes in the left and right directions. It can achieve a high level of load-bearing capacity in the height or vertical direction, while achieving a smaller stiffness in the lateral or left and right directions, which is beneficial to improving the vibration isolation rate.

[0046] Furthermore, this suspension support device achieves good vibration isolation and damping effects through its upper, left, lower, and right vibration isolation supports, reducing the number of components and eliminating the traditional method of suspension with dampers and springs. This results in a more compact structure and significantly reduces the space occupied by the enclosure. Additionally, it avoids the relative movement of traditional rigidly connected structural components, thus preventing structural noise generated during component operation.

[0047] The rigid frame helps improve the reliability of the support suspension device. Furthermore, the upper and / or lower vibration isolation support parts with rigid frames do not require a large number of connection structures, which facilitates the realization of elastic support components and can further reduce the number of parts and further simplify the structure.

[0082] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0083] like Figures 1 to 9 As shown, this embodiment provides a support and suspension device 100 and a washing machine 200 including the same. In addition to the support and suspension device 100, the washing machine 200 also includes a cabinet 300 and a drum 400. Figures 1 to 3 As shown, there are two cylinders 400 connected together by a cylinder connecting part 500, and each cylinder 400 is suspended from the box body 300 by a support suspension device 100. In other alternative embodiments, there may be multiple cylinders 400, in which case each cylinder 400 may be suspended from the box body 300 by a support suspension device 100. In other alternative embodiments, there may be multiple cylinders 400, in which case adjacent cylinders 400 are connected to each other, and the two cylinders 400 at both ends are suspended from the box body 300 by a support suspension device 100.

[0084] In the washing machine 200, each of the multiple drums 400 can be connected to the cabinet 300 through the support and suspension device 100 according to actual layout requirements, or only the two drums 400 at both ends can be connected to the cabinet 300 through the support and suspension device 100. The layout is flexible, as long as the reliable suspension of the drums 400 can be met.

[0085] It should be noted that the weight of cylinder 400 in this article includes the weight of cylinder 400 itself and the weight of its internal load, and not just the weight of cylinder 400 itself. Of course, when cylinder 400 is unloaded, the weight of cylinder 400 corresponds to the weight of cylinder 400 itself.

[0086] Specifically, regarding the support suspension device 100, such as Figures 1 to 9As shown, the support suspension device 100 is used to suspend the washing machine drum 400 from the washing machine housing 300. The support suspension device 100 includes a first bracket 10, a second bracket 20, an elastic support assembly 30, and a rigid frame (see the upper rigid frame 40 and lower rigid frame 50 below). The first end of the first bracket 10 is used to connect to the housing 300; the first end of the second bracket 20 is used to connect to the drum 400. The elastic support assembly 3030 is made of elastic material and has a ring-shaped structure. Along the circumferential direction, it includes an upper vibration isolation support 301, a left vibration isolation support 302, a lower vibration isolation support 303, and a right vibration isolation support 304. The upper vibration isolation support 301 is used to connect to the second end of the second bracket 20, and the lower vibration isolation support 303 is used to connect to the second end of the first bracket 10. The left vibration isolation support 302 and the right vibration isolation support 304 both extend vertically and are respectively connected between the upper vibration isolation support 301 and the lower vibration isolation support 303. The rigid frame is made of a rigid material and is embedded in the upper vibration isolation support 301 and / or the lower vibration isolation support 303. The upper vibration isolation support 301 is configured to move closer to or further away from the lower vibration isolation support 303 in the left-right direction as the weight of the cylinder changes.

[0087] In this embodiment, the elastic support assembly 30 includes an upper vibration isolation support 301, a left vibration isolation support 302, a lower vibration isolation support 303, and a right vibration isolation support 304, all made of elastic material and forming a ring structure. This arrangement helps to reduce vibrations transmitted from the drum to the housing. The left and right vibration isolation supports 302 and 304 can achieve varying stiffness in the height or vertical direction. When the drum load is high, such as during washing, the left and right vibration isolation supports 302 and 304 exhibit greater compression and stiffness in the height or vertical direction, ensuring reliable load-bearing. When the drum load is low, such as during spin-drying, the compression and stiffness of the first vibration isolation support decrease, improving the vibration isolation rate. In other words, this suspension support device provides good support stiffness in the height or vertical direction, avoiding the problem of instability and deformation in compression suspension systems. In addition, the lower vibration isolation support 303 can move in the left and right directions relative to the upper vibration isolation support 301, thereby achieving stiffness changes in the left and right directions. It can achieve a high level of load-bearing capacity in the height or vertical direction while achieving a smaller stiffness in the lateral or left and right directions, which is beneficial to improving the vibration isolation rate.

[0088] Furthermore, this suspension support device, through the upper vibration isolation support 301, left vibration isolation support 302, lower vibration isolation support 303, and right vibration isolation support 304, achieves good vibration isolation and damping effects, reduces the number of parts, eliminates the traditional method of vibration dampers and suspension springs, resulting in a more compact structure and significantly reducing the space occupied by the housing. Additionally, it avoids the relative movement of traditional rigidly connected structural components, thus preventing structural noise generated during component operation.

[0089] The rigid frame helps improve the reliability of the support suspension device 100. The upper vibration isolation support 301 and / or lower vibration isolation support 303 with rigid frames do not need to have many connection structures, which facilitates the realization of the elastic support assembly 30 and can further reduce the number of parts and further simplify the structure.

[0090] In specific configuration, depending on actual needs, a rigid frame can be embedded only on the upper vibration isolation support 301, or only on the lower vibration isolation support 303, or both the upper vibration isolation support 301 and the lower vibration isolation support 303 can be embedded simultaneously.

[0091] Specifically, in this embodiment, such as Figure 6 and Figure 7 As shown, both the upper vibration isolation support 301 and the lower vibration isolation support 303 are fitted with rigid frames.

[0092] Reference Figures 6 to 8 It is understood that mounting grooves 306 are provided inside the upper vibration isolation support 301 and at the top of the lower vibration isolation support 303, and the rigid frame is embedded in the mounting grooves 306. Preferably, the top surface of the rigid frame is aligned with the top surface of the corresponding upper vibration isolation support 301 and / or lower vibration isolation support 303. The rigid frame is positioned within the mounting grooves 306 of the upper vibration isolation support 301 and / or lower vibration isolation support 303, facilitating installation and not occupying additional space outside the upper vibration isolation support 301 and / or lower vibration isolation support 303, thus reducing the space occupied by the support suspension device 100.

[0093] As a preferred setting method, such as Figures 6 to 9As shown, the rigid frame has multiple protruding engaging portions 60 on both sides along the extending direction, and the mounting groove 306 is correspondingly provided with multiple slot units 307; wherein, the multiple protruding engaging portions 60 and the multiple slot units 307 engage one-to-one. The rigid frame adopts a fishbone-like structure. Through the cooperation of the multiple protruding engaging portions 60 and the multiple slot units 307, the rigid frame has more contact positions and connection surfaces with the upper vibration isolation support 301 and / or the lower vibration isolation support 303, thereby having a larger contact area, which is beneficial to improving the reliability of the connection between the rigid frame and the upper vibration isolation support 301 and / or the lower vibration isolation support 303.

[0094] As an example, five protruding engaging parts 60 are provided on each side of the rigid frame. The protruding engaging parts 60 are cuboid structures, and the protruding engaging parts 60 on both sides of the rigid frame are symmetrically arranged.

[0095] In other alternative embodiments, the number of protruding engagement portions 60 can be flexibly adjusted according to actual needs, and the protruding engagement portions 60 on both sides of the rigid frame can also be set in an asymmetrical form.

[0096] Based on the above-mentioned snap-fit ​​connection, the rigid frame can also be bonded to the upper vibration isolation support 301 and the lower vibration isolation support 303, and / or bonded through a vulcanization process to make the connection more reliable.

[0097] like Figures 4 to 8 As shown, both the left vibration isolation support 302 and the right vibration isolation support 304 have bent portions 305 along their extension direction. The bent portion 305 on either the left or right vibration isolation support 302 bends towards the other of the two supports. The bent portions 305 facilitate elastic deformation of the left and right vibration isolation supports 302 and 304, improving their deformation capacity and further ensuring load-bearing performance. In this embodiment, the two bent portions 305 are positioned facing each other, resulting in a more compact structure.

[0098] Reference Figures 4 to 8 It is understood that, for either the left vibration isolation support 302 or the right vibration isolation support 304, the thickness at the bend 305 is greater than the thickness of the rest. This design, with a larger thickness at the bend 305, increases stiffness during deformation in the height or vertical direction, thereby further improving load-bearing capacity.

[0099] As a preferred configuration, the thickness of either the left vibration isolation support 302 or the right vibration isolation support 304 decreases from the bending portion 305 to the end near the upper vibration isolation support 301. Further, or alternatively, the thickness of either the left vibration isolation support 302 or the right vibration isolation support 304 decreases from the bending portion 305 to the end near the lower vibration isolation support 303. This configuration can significantly reduce material consumption while maintaining overall load-bearing capacity, thus helping to lower costs.

[0100] Continue to refer to Figures 4 to 8 It is understood that, in the front-rear direction, the two ends of the lower vibration isolation support 303 extend out to the two ends of the upper vibration isolation support 301. Here, the two ends of the lower vibration isolation support 303 extending out to the two ends of the upper vibration isolation support 301, on the one hand, allows the lower vibration isolation support 303 and the first bracket 10 to have a larger contact area, which is beneficial to improving the connection reliability; on the other hand, the portion of the lower vibration isolation support 303 extending out to the upper vibration isolation support 301 can serve as a carrier for setting up a connection structure for connecting with the first bracket 10, facilitating the installation of the connection structure.

[0101] Furthermore, in this embodiment, as a preferred configuration, the upper vibration isolation support 301, the left vibration isolation support 302, the lower vibration isolation support 303, and the right vibration isolation support 304 are integrally formed structures. The integrally formed design simplifies the structure of the support suspension device 100 and also helps reduce the space occupied by the support suspension device 100. In addition, integrally formed components are generally less likely to be damaged or broken into several parts when subjected to the large gravity of the cylinder, which helps ensure the overall reliability of the support suspension device 100.

[0102] In other alternative embodiments, the upper vibration isolation support 301, the left vibration isolation support 302, the lower vibration isolation support 303, and the right vibration isolation support 304 may also be partially configured as an integral structure, or each may be independently formed and then connected together.

[0103] like Figure 4 and Figure 5 As shown, the first end of the first bracket 10 is connected to the inner wall of the housing, and the second end of the first bracket 10 is attached to and connected to the side of the lower vibration isolation support 303 opposite to the upper vibration isolation support 301. The first end of the second bracket 20 is connected to the outer wall of the cylinder, and the second end of the second bracket 20 is attached to and connected to the side of the upper vibration isolation support 301 opposite to the lower vibration isolation support 303. The first bracket 10 is attached to the lower vibration isolation support 303, and the contact area between them is relatively large, thus achieving a more reliable connection; the second bracket 20 is attached to the upper vibration isolation support 301, and the contact area between them is relatively large, thus achieving a more reliable connection.

[0104] The specific structures of the first support 10 and the second support 20 are not limited; for example, as shown below. Figure 4 and Figure 5 As shown, the first support 10 includes a first connecting portion 101 and a second connecting portion 102 connected together, and the second support 20 includes a third connecting portion 201 and a fourth connecting portion 202 connected together. The first connecting portion 101 is used to connect to the inner wall of the housing, and the second connecting portion 102 is used to fit against the lower vibration isolation support portion 303. The third connecting portion 201 is used to connect to the outer wall of the cylinder, and the fourth connecting portion 202 is used to fit against the upper vibration isolation support portion 301.

[0105] For ease of description, the rigid frame installed on the upper vibration isolation support 301 is referred to as the upper rigid frame 40, and the rigid frame installed on the lower vibration isolation support 303 is referred to as the lower rigid frame 50. Multiple first connecting holes 103 are provided on the second end of the first bracket 10, the lower rigid frame 50, and the lower vibration isolation support 303. The first bracket 10 and the lower rigid frame 50 are detachably connected by multiple first threaded fasteners passing through the multiple first connecting holes 103. Multiple second connecting holes 203 are provided on the second end of the second bracket 20, the upper rigid frame 40, and the upper vibration isolation support 301. The second bracket 20 and the upper rigid frame 40 are detachably connected by multiple second threaded fasteners passing through the multiple second connecting holes 203. The horizontal projection of the multiple first connecting holes 103 is located outside the horizontal projection of the multiple second connecting holes 203.

[0106] The first connecting hole 103 is used to connect the lower vibration isolation support 303 to the housing, and the second connecting hole 203 is used to connect the upper vibration isolation support 301 to the cylinder. The connection position of the upper vibration isolation support 301 to the cylinder is located above the connection position of the lower vibration isolation support 303 to the housing. The horizontal projection of the multiple first connecting holes 103 is set outside the horizontal projection of the multiple second connecting holes 203, which is equivalent to setting the first connecting holes 103 outside the second connecting holes 203. The first connecting holes 103 and the second connecting holes 203 are staggered to provide a larger operating space for the installation of the first threaded fastener, thus facilitating the installation of the second threaded fastener. In addition, the lower rigid frame 50 serves as the carrier for setting the first connecting holes 103, and the upper rigid frame 40 serves as the carrier for setting the second connecting holes 203. This convenient operation helps to ensure the load-bearing and vibration isolation capabilities of the elastic support assembly 30.

[0107] It should be noted that, in this embodiment, the thickness of the upper vibration isolation support 301 is basically the same as the thickness of the lower vibration isolation support 303, and is not much different from the thickness of the remaining parts of the left vibration isolation support 302 and the right vibration isolation support 304 except for the bending part 305.

[0108] As an example, the second connecting portion 102, the lower rigid frame 50, and the upper vibration isolation support portion 301 of the first bracket 10 are each provided with two first connecting holes 103, and the fourth connecting portion 202, the upper rigid frame 40, and the lower vibration isolation support portion 303 of the second bracket 20 are each provided with two second connecting holes 203. In other alternative embodiments, the specific number can be flexibly set according to actual needs.

[0109] As an example, the upper vibration isolation support 301, left vibration isolation support 302, lower vibration isolation support 303, and right vibration isolation support 304 are all made of rubber, while the first bracket 10 and the second bracket 20 are made of a rigid material, such as 45 steel. In other alternative embodiments, the upper vibration isolation support 301, left vibration isolation support 302, lower vibration isolation support 303, and right vibration isolation support 304 can be made of other elastic materials, in addition to rubber.

[0110] In this embodiment, the specific material of the rigid frame is not limited, but it is preferably made of metal. The specific material can be selected according to actual setup requirements and considerations such as cost.

[0111] The washing machine 200 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the washing machine 200 to perform corresponding operations, thereby realizing intelligent control of the washing machine 200 and improving the user experience.
