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, the elastic support assembly being made of an elastic material, the elastic support assembly including a first vibration isolation support part and a second vibration isolation support part;

[0012] The first vibration isolation support has a cylindrical end, a vibration isolation support body and a box end connected along the height direction. The cylindrical end is used to connect to the second end of the second bracket, the box end is used to connect to the second end of the first bracket, and the vibration isolation support body is supported between the cylindrical end and the box end.

[0013] The second vibration isolation support is disposed on the end of the cylinder and extends from the end of the cylinder toward the end of the box body;

[0014] The second vibration isolation support portion is configured such that one end facing the box end is able to move closer to or further away from the box end relative to the weight of the cylinder, and can move relative to the box end in the horizontal plane in a direction that approaches or moves away from the vibration isolation support body.

[0015] In this design, the elastic support assembly comprises a first vibration-damping support and a second vibration-damping support, both made of elastic material. This arrangement helps reduce vibrations transmitted from the drum to the housing. The first vibration-damping support allows for changes in stiffness in the vertical or height direction. When the drum is under heavy load, such as during washing, the first vibration-damping support exhibits greater compression and stiffness in the vertical or height direction, ensuring reliable load-bearing. Conversely, when the drum is under light load, such as during spin-drying, the compression and stiffness in the vertical or height direction decrease, improving the vibration isolation rate. In other words, this suspension support device provides good support stiffness in the vertical or height direction, preventing instability and deformation issues associated with compression suspensions. Furthermore, the second vibration-damping support can move horizontally relative to the housing end of the first vibration-damping support, enabling changes in stiffness in the horizontal plane. This allows for high load-bearing capacity in the vertical or height direction while maintaining lower stiffness in the lateral direction, further enhancing the vibration isolation rate.

[0016] Furthermore, this suspension support device achieves better vibration isolation and damping effects through the first and second vibration isolation support parts, reducing the number of parts and eliminating the traditional method of suspension with shock absorbers and springs. The structure is more compact, significantly reducing 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.

[0017] Preferably, one end of the second vibration isolation support facing the box end is configured to switch between a first position state and a second position state relative to the box end as the weight of the cylinder changes.

[0018] When in the first position, the end of the second vibration isolation support facing the box end is stationary relative to the box end and is located above or in contact with the box end;

[0019] When in the second position, one end of the second vibration isolation support facing the box end abuts against the box end and moves relative to the box end in the horizontal plane in a direction that approaches or moves away from the vibration isolation support body.

[0020] In this scheme, using the above-described structural configuration, in the first position state, when the load or gravity of the cylinder is relatively small or the cylinder is unloaded, the second vibration isolation support is basically stationary relative to the box end of the first vibration isolation support. The second vibration isolation support can be positioned above the box end of the first vibration isolation support or only in contact with the box end, depending on actual needs. When the load or gravity of the cylinder is relatively large, the cylinder moves left and right in the horizontal plane relative to the box. Correspondingly, the end of the second vibration isolation support facing the box end moves relative to the box end in a direction closer to or further away from the vibration isolation support body, thereby achieving a change in lateral stiffness.

[0021] Preferably, the end of the second vibration isolation support facing the box end is an arc-shaped structure. When in the second position, the arc-shaped structure can roll on the surface of the box end to move closer to or away from the vibration isolation support body.

[0022] In this solution, the above-mentioned structural configuration is adopted. The second vibration isolation support part moves relative to the box end by rolling relative to the box end. The movement is simple and the friction between the second vibration isolation support part and the box end is small, making it less likely to damage the second vibration isolation support part and the box end.

[0023] Preferably, in the horizontal plane, the second vibration isolation support portion is spaced apart from the vibration isolation support body.

[0024] In this solution, the above-mentioned structural arrangement ensures that there is always a gap between the second vibration isolation support and the vibration isolation support body, preventing the second vibration isolation support from touching the vibration isolation support body during the movement of the box end relative to the first vibration isolation support, thus preventing an increase in lateral stiffness.

[0025] Preferably, the cross-sectional dimensions of the second vibration isolation support decrease from the cylindrical end to the box end.

[0026] In this solution, the above-mentioned structural configuration has the advantages of reducing material usage. On the other hand, in order to realize the movement of the second vibration isolation support relative to the box end, there is no need to set up a large activity space, which helps to simplify the overall structure and reduce the overall space occupied by the support suspension device.

[0027] Preferably, the cylindrical end, the vibration isolation support body, and the box end are integrally formed structures;

[0028] Alternatively, the cylindrical end, the vibration isolation support body, the box end, and the second vibration isolation support part are integrally formed structures.

[0029] In this design, the aforementioned structural configuration simplifies the structure of the support and suspension device through a one-piece molding, and also helps to reduce the space occupied by the support and suspension device. Furthermore, the one-piece molded component is generally less prone to damage or breakage into several parts when subjected to the significant gravity of the cylinder, which helps ensure the overall reliability of the support and suspension device.

[0030] Preferably, the first bracket includes a first connecting frame, a first end of the first connecting frame is used to connect to the inner wall of the box, and a second end of the first connecting frame is attached to and connected to the side of the box that is away from the cylindrical end;

[0031] And / or, the second bracket includes a second connecting frame, the first end of which is connected to the outer wall of the cylinder, and the second end of which is attached to and connected to the side of the cylinder opposite to the box end.

[0032] In this solution, the above-mentioned structural configuration is adopted. The first connecting frame is attached to the end of the box, and the contact area between the two is relatively large, thereby achieving a more reliable connection; the second connecting frame is attached to the end of the cylinder, and the contact area between the two is relatively large, thereby achieving a more reliable connection.

[0033] Preferably, the first bracket further includes a first connecting plate, which is disposed opposite to the first connecting frame and located on both sides of the housing end. The first connecting frame, the housing end, and the first connecting plate are all provided with a plurality of first connecting holes. The first connecting frame, the housing end, and the first connecting plate are detachably connected by a plurality of first threaded fasteners passing through the plurality of first connecting holes. The first connecting plate is provided with an avoidance structure for avoiding the vibration isolation support body.

[0034] The second bracket also includes a second connecting plate, which is disposed opposite to the second connecting frame and located on both sides of the cylindrical end. The second connecting frame, the cylindrical end, and the second connecting plate are all provided with a plurality of second connecting holes. The second connecting frame, the cylindrical end, and the second connecting plate are detachably connected by a plurality of second threaded fasteners passing through the plurality of second connecting holes. The second connecting plate is provided with a clearance structure for avoiding the vibration isolation support body and the second vibration isolation support part.

[0035] In this solution, the above-mentioned structural configuration, including the first connecting plate and the second connecting plate, can further improve the reliability of the connection between the first vibration isolation support and the box and cylinder.

[0036] Preferably, in the height direction, the cylindrical end is located above the box end, and the horizontal projection of the plurality of first connecting holes is located outside the horizontal projection of the plurality of second connecting holes.

[0037] In this design, the first connecting hole is used to connect the first vibration isolation support to the housing, and the second connecting hole is used to connect the first vibration isolation support to the cylinder. The position where the cylinder end of the first vibration isolation support connects to the housing is located above the position where the housing end of the first vibration isolation support connects to the housing. The horizontal projection of the first connecting hole is set to be outside the horizontal projection of the multiple second connecting holes, which is equivalent to setting the first connecting hole outside the second connecting hole. The first connecting hole and the second connecting hole are staggered to reserve a larger operating space for the installation of the first threaded fastener, thus facilitating the installation of the first threaded fastener.

[0038] This utility model also provides a washing machine, which includes a cabinet, a drum and the above-mentioned support and suspension device;

[0039] There are multiple cylindrical bodies, each of which is suspended from the box body by the support and suspension device; or,

[0040] 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.

[0041] 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.

[0042] The positive and progressive effects of this utility model are as follows:

[0043] In this application, the elastic support assembly includes a first vibration-damping support and a second vibration-damping support, made of elastic material. This arrangement helps to reduce vibrations transmitted from the drum to the housing. The first vibration-damping support enables changes in stiffness in the vertical or height direction. When the drum is under heavy load, such as during washing, the first vibration-damping support exhibits greater compression and stiffness in the vertical or height 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 height direction, avoiding the instability and deformation problems associated with compression suspension. Furthermore, the second vibration-damping support can move horizontally relative to the housing end of the first vibration-damping support, thereby enabling changes in stiffness in the horizontal plane. This allows for high load-bearing capacity in the vertical or height direction while maintaining lower stiffness in the lateral direction, further enhancing the vibration isolation rate.

[0044] Furthermore, this suspension support device achieves better vibration isolation and damping effects through the first and second vibration isolation support parts, reducing the number of parts and eliminating the traditional method of suspension with shock absorbers and springs. The structure is more compact, significantly reducing 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.

[0079] 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.

[0080] like Figures 1 to 10 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.

[0081] 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.

[0082] Specifically, regarding the support suspension device 100, such as Figures 1 to 10As shown, the support and suspension device 100 is used to suspend the drum 400 of the washing machine from the casing 300 of the washing machine. The support and suspension device 100 includes a first bracket 10, a second bracket 20, and an elastic support assembly 30. The first end of the first bracket 10 is used to connect to the casing 300; the first end of the second bracket 20 is used to connect to the drum 400; the elastic support assembly 30 is made of elastic material and includes a first vibration isolation support portion 40 and a second vibration isolation support portion 50. The first vibration isolation support portion 40 has a drum end 403, a vibration isolation support body 402, and a casing end 401 connected along the height direction. The drum end 403 is used to connect to the second end of the second bracket 20, and the casing end 401 is used to connect to the second end of the first bracket 10. The vibration isolation support body 402 is supported between the drum end 403 and the casing end 401. The second vibration isolation support portion 50 is disposed on the drum end 403 and extends from the drum end 403 toward the casing end 401. The second vibration isolation support 50 is configured such that one end facing the box end 401 is able to move closer to or further away from the box end 401 as the weight of the cylinder 400 changes, and can move in the horizontal plane relative to the box end 401 in the direction of approaching or moving away from the vibration isolation support body 402.

[0083] 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.

[0084] In this embodiment, the elastic support assembly 30 includes a first vibration isolation support portion 40 and a second vibration isolation support portion 50, made of elastic material. This arrangement helps to reduce the vibration transmitted from the drum 400 to the housing 300. The first vibration isolation support portion 40 enables the function of varying stiffness in the height or vertical direction. When the load on the drum 400 is large, such as during washing, the first vibration isolation support portion 40 has a large compression amount and high stiffness in the height or vertical direction, achieving reliable load bearing. When the load on the drum 400 is small, such as during spin-drying, the compression amount and stiffness of the first vibration isolation support portion 40 in the height or vertical direction decrease, thereby improving the vibration isolation rate. In other words, this suspension support device can have good support stiffness in the height or vertical direction, avoiding the problem of instability and deformation of compression suspension.

[0085] The second vibration isolation support 50 can move horizontally relative to the box end 401 of the first vibration isolation support 40, thereby achieving stiffness variation in the horizontal plane. It can achieve a high level of load-bearing capacity in the height or vertical direction while maintaining a relatively low stiffness in the lateral direction, which is beneficial for improving the vibration isolation rate.

[0086] Furthermore, this suspension support device, through the first vibration isolation support part 40 and the second vibration isolation support part 50, can achieve better vibration isolation and damping effects, reducing the number of parts and eliminating the traditional method of suspension with shock absorbers and springs. The structure is more compact, significantly reducing the space occupied by the housing 300. Additionally, it avoids the relative movement of traditional rigidly connected structural components, thus preventing structural noise generated during component operation.

[0087] The position of the second vibration isolation support 50 relative to the housing end 401 of the first vibration isolation support 400 changes according to the change in the gravity of the cylinder 400. As an example, in this embodiment, the end of the second vibration isolation support 50 facing the housing end 401 is configured to switch between a first position state and a second position state relative to the housing end 401 as the gravity of the cylinder 400 changes. In the first position state, the end of the second vibration isolation support 50 facing the housing end 401 is stationary relative to the housing end 401 and is located above or in contact with the housing end 401; in the second position state, the end of the second vibration isolation support 50 facing the housing end 401 abuts against the housing end 401 and moves relative to the housing end 401 in the horizontal plane in a direction that approaches or moves away from the vibration isolation support body 402.

[0088] In the first position, when the load or weight on the cylinder 400 is relatively small or the cylinder 400 is unloaded, the second vibration isolation support 50 is basically stationary relative to the box end 401 of the first vibration isolation support 40. The second vibration isolation support 50 can be positioned above the box end 401 of the first vibration isolation support 40 or only in contact with the box end 401, depending on actual needs. When the load or weight on the cylinder 400 is relatively large, the cylinder 400 moves left and right in the horizontal plane relative to the box 300. Correspondingly, the end of the second vibration isolation support 50 facing the box end 401 moves relative to the box end 401 in a direction closer to or further away from the vibration isolation support body 402, thereby achieving a change in lateral stiffness.

[0089] like Figures 4 to 10 As shown, the end of the second vibration isolation support 50 facing the housing end 401 is an arc-shaped structure. When in the second position, the arc-shaped structure can roll on the surface of the housing end 401 to move closer to or away from the vibration isolation support body 402. That is, in this embodiment, the second vibration isolation support 50 moves relative to the housing end 401 by rolling relative to it. The movement is simple, and the friction between the second vibration isolation support 50 and the housing end 401 is small, making it less likely to damage the second vibration isolation support 50 and the housing end 401.

[0090] In other alternative embodiments, the end of the second vibration isolation support 50 facing the housing end 401 may be configured to slide relative to the housing end 401 to achieve movement, without specific limitations.

[0091] Reference Figures 4 to 10 It is understood that, in the horizontal plane, the second vibration isolation support 50 and the vibration isolation support body 402 are spaced apart.

[0092] This arrangement ensures that there is always a gap between the second vibration isolation support 50 and the vibration isolation support body 402, preventing the second vibration isolation support 50 from touching the vibration isolation support body 402 during the movement of the box end 401 of the first vibration isolation support 40, which would lead to an increase in lateral stiffness.

[0093] As for the gap range between the second vibration isolation support 50 and the vibration isolation support body 402, it is not specifically limited here, as long as it can meet the space requirements and enable the second vibration isolation support 50 to have sufficient travel.

[0094] Continue to refer to Figures 4 to 10 It is understood that the cross-sectional dimensions of the second vibration isolation support 50 decrease from the cylindrical end 403 to the box end 401. This arrangement has two advantages: firstly, it reduces the amount of material used; secondly, in order to enable the second vibration isolation support 50 to move relative to the box end 401, a large space is not required, which simplifies the overall structure and reduces the overall space occupied by the support suspension device 100.

[0095] As a preferred configuration, the cylindrical end 403, the vibration isolation support body 402, and the box end 401 are integrally formed structures. In fact, further, in this embodiment, the cylindrical end 403, the vibration isolation support body 402, the box end 401, and the second vibration isolation support part 50 are integrally formed structures, that is, the elastic support assembly 30 is an integrally formed structure.

[0096] Here, the one-piece design simplifies the structure of the support suspension device 100 and also helps to reduce the space occupied by the support suspension device 100. In addition, the one-piece molded component is generally not easily damaged or broken into several parts when subjected to the large gravity of the cylinder 400, which helps to ensure the overall reliability of the support suspension device 100.

[0097] like Figures 1 to 7As shown, the first support 10 includes a first connecting frame 101, the first end of which is connected to the inner wall of the housing 300, and the second end of which is attached to and connected to the side of the housing end 401 opposite to the cylindrical end 403. Correspondingly, the second support 20 includes a second connecting frame 201, the first end of which is connected to the outer wall of the cylindrical end 400, and the second end of which is attached to and connected to the side of the cylindrical end 403 opposite to the housing end 401.

[0098] In this embodiment, the first connecting bracket 101 is attached to the box end 401, and the contact area between the two is relatively large, thereby achieving a relatively reliable connection. The second connecting bracket 201 is attached to the cylinder end 403, and the contact area between the two is relatively large, thereby achieving a relatively reliable connection.

[0099] The specific structures of the first connecting frame 101 and the second connecting frame 201 are not limited; for example, such as... Figures 1 to 6 As shown, the first connecting frame 101 includes a first connecting portion 1011 and a second connecting portion 1012 connected together, and the second connecting frame 201 includes a third connecting portion 2011 and a fourth connecting portion 2012 connected together. The first connecting portion 1011 is used to connect to the inner wall of the housing 300, and the second connecting portion 1012 is used to fit against the housing end 401. The third connecting portion 2011 is used to connect to the outer wall of the cylinder 400, and the fourth connecting portion 2012 is used to fit against the cylinder end 403.

[0100] Furthermore, the first bracket 10 also includes a first connecting plate 102, which is disposed opposite to the first connecting frame 101 and located on both sides of the housing end 401. The first connecting frame 101, the housing end 401 and the first connecting plate 102 are all provided with a plurality of first connecting holes 103. The first connecting frame 101, the housing end 401 and the first connecting plate 102 are detachably connected by a plurality of first threaded fasteners passing through the plurality of first connecting holes 103. The first connecting plate 102 is provided with a clearance structure for clearance of the vibration isolation support body 402. The second support 20 also includes a second connecting plate 202, which is disposed opposite to the second connecting frame 201 and located on both sides of the cylindrical end 403. The second connecting frame 201, the cylindrical end 403 and the second connecting plate 202 are each provided with a plurality of second connecting holes 203. The second connecting frame 201, the cylindrical end 403 and the second connecting plate 202 are detachably connected by a plurality of second threaded fasteners passing through the plurality of second connecting holes 203. The second connecting plate 202 is provided with a clearance structure for avoiding the vibration isolation support body 402 and the second vibration isolation support part 50.

[0101] By setting the first connecting plate 102 and the second connecting plate 202, the reliability of the connection between the first vibration isolation support 40 and the box 300 and the cylinder 400 can be further improved.

[0102] In this embodiment, because a first connecting plate 102 is provided, the end of the second vibration isolation support 50 facing the housing end 401 rolls relative to the first connecting plate 102.

[0103] As an example, the first connecting frame 101, the box end 401, and the first connecting plate 102 are each provided with two first connecting holes 103, and the second connecting frame 201, the cylinder end 403, and the second connecting plate 202 are each provided with two second connecting holes 203. In other alternative embodiments, the specific number can be flexibly set according to actual needs.

[0104] As a preferred configuration, the first connecting plate 102 is aligned with the edge of the housing end 401, and the second connecting plate 202 is aligned with the edge of the cylinder end 403, so as to achieve the largest possible contact area and also to protect the housing end 401 and the cylinder end 403.

[0105] like Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, in the height direction, the cylindrical end 403 is located above the box end 401, and the horizontal projections of the multiple first connecting holes 103 are located outside the horizontal projections of the multiple second connecting holes 203. The first connecting holes 103 are used to connect the first vibration isolation support 40 to the box 300, and the second connecting holes 203 are used to connect the first vibration isolation support 40 to the cylindrical end 400. The connection position between the cylindrical end 403 and the cylindrical end 400 of the first vibration isolation support 40 is located above the connection position between the box end 401 and the box 300. Setting the horizontal projection of the first connecting hole 103 outside the horizontal projections of the multiple second connecting holes 203 is equivalent to setting the first connecting hole 103 outside the second connecting holes 203. The staggered arrangement of the first connecting holes 103 and the second connecting holes 203 provides a larger operating space for installing the first threaded fastener, thus facilitating the installation of the first threaded fastener.

[0106] As an example, both the first vibration isolation support 40 and the second vibration isolation support 50 are made of rubber.
