The suspension device includes a first bracket, a second bracket, an elastic support assembly, a bending-resistant load-bearing member, and at least two reinforcing members. The reinforcing members act on the second end of the elastic support assembly to provide a force to the second end of the elastic support assembly in the opposite direction to the deformation of the first end of the elastic support assembly. At least one of the reinforcing members has a through hole, and the area of ​​the through hole is not less than half the area of ​​the reinforcing member.

Description

Technical Field

[0001] This utility model relates to the field of washing machines, and in particular to a hanging 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) Fixed stiffness and damping parameters cannot meet dynamic requirements. During the washing stage, the drum contains clothes and water, resulting in a large overall mass. At this time, the suspension springs need to have high stiffness to support the weight and prevent significant drum displacement. During the spin-drying stage, only clothes remain in the drum, and the moisture content of the clothes gradually decreases, reducing the drum's mass. Simultaneously, the rotational speed increases, intensifying vibration. At this point, the suspension springs need to have relatively low stiffness to improve the vibration isolation rate of the suspension system. However, existing shock absorbers and suspension springs, once designed, have fixed stiffness and damping parameters that cannot be adjusted according to changes in operating conditions, making it difficult to meet ideal control requirements.

[0005] 2) The structure is not compact enough and occupies a large amount of space. The suspension springs and vibration dampers are distributed at the upper and lower ends of the cylinder, respectively, and connected to the housing. This layout makes the overall structure not compact enough, occupies a large amount of internal space in the housing, and affects the arrangement of other components.

[0006] 3) Existing technologies have the problem of low stiffness on the bearing side, which leads to excessive deformation on the vibration isolation bearing side and loss of bearing function.

[0007] 4) Existing technology has a problem of mismatch between the front and rear rigidity of the washing machine body, which causes the front of the drum to sink when installed, resulting in increased tensile stress on the front door seal and easy damage to the door seal. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the problem of low stiffness on the bearing side of the suspension device in the prior art, which leads to excessive deformation on the vibration isolation bearing side and loss of bearing function, as well as the problem of mismatch between the front and rear stiffness of the washing machine body, which causes the front of the drum to sink in the installation state, resulting in increased tensile stress on the front door seal and easy damage to the door seal. The present invention provides a suspension device and a washing machine containing the same.

[0009] The present invention solves the above-mentioned technical problems through the following technical solution:

[0010] A suspension device for suspending the drum of a washing machine from the casing of the washing machine, the suspension device comprising:

[0011] The first bracket, the first end of the first bracket is used to connect to the box body;

[0012] The second support, the first end of which is used to connect to the cylinder;

[0013] An elastic support assembly, the first end of which is connected to the second end of the first bracket, and the second end of which is connected to the second end of the second bracket, wherein the deformation of the second end of the elastic support assembly is configured to change with the gravity of the cylinder, so as to move closer to or further away from the first end of the elastic support assembly.

[0014] A bending-resistant bearing member is disposed at the second end of an elastic support assembly, wherein the bending-resistant bearing member is configured to act on the elastic support assembly and compress the second end of the elastic support assembly when the elastic support assembly deforms; and

[0015] At least two reinforcing members are provided, which act on the second end of the elastic support assembly to provide a force to the second end of the elastic support assembly in the opposite direction to the deformation of the first end of the elastic support assembly. At least one of the reinforcing members has a through hole, and the area of ​​the through hole is not less than half the area of ​​the reinforcing member.

[0016] In this design, the elastic support component provides support and cushioning for the drum. The bending load-bearing component converts the bending of the second end of the elastic support component into a compressive load on the second end of the elastic support component, thereby improving the bending load-bearing capacity of the second end of the elastic support component. This helps prevent excessive deformation of the elastic support component on the load-bearing side of the washing machine, which could lead to loss of load-bearing function. Furthermore, the second end of the elastic support component moves closer to or further away from the first end as the weight of the drum changes. This design can support the drum when it becomes heavier and provide good vibration isolation when it becomes lighter. At least one reinforcing member has a through hole, and the area of ​​the through hole is not less than half the area of ​​the reinforcing member. This makes the reinforcing member lighter and the increase in stiffness limited, preventing poor vibration isolation of the suspension device. Since the increase in stiffness of a single reinforcing member is limited, setting at least two reinforcing members can compensate for the required stiffness, increase the load-bearing capacity of the suspension device, prevent the front of the drum from sinking in the installed state, which would increase the tensile stress on the front door seal and make the door seal easily damaged. This also ensures that the suspension device maintains a good vibration isolation effect.

[0017] Preferably, the elastic support assembly includes a first vibration isolation support part, a connecting part, and a second vibration isolation support part connected end to end. The first vibration isolation support part, the connecting part, and the second vibration isolation support part are made of elastic material. The first vibration isolation support part is connected to the first bracket, and the second vibration isolation support part is connected to the second bracket.

[0018] The bending bearing member is located on the side of the second vibration isolation support facing the first vibration isolation support.

[0019] In this design, the elastic support assembly includes a first vibration isolation support, a connecting part, and a second vibration isolation support made of elastic material. This arrangement helps to reduce the vibration transmitted from the cylinder to the box and provides flexible buffering for the cylinder's vibration. Furthermore, the placement of the bending load-bearing member can first prevent the second vibration isolation support from deforming excessively, and then prevent the first vibration isolation support and the connecting part from deforming excessively. If the bending load-bearing member is placed on the first vibration isolation support or the connecting part, the second vibration isolation support may still easily deform excessively on the bearing side of the cylinder.

[0020] Preferably, the second vibration isolation support has a first end connected to the second bracket and a second end away from the second bracket along the extending direction. Along the extending direction of the second vibration isolation support, the bending load-bearing member includes a first pressure plate, which is attached to the second vibration isolation support to press the second vibration isolation support from the side.

[0021] In this scheme, along the extension direction of the second vibration isolation support, the bending load-bearing member includes a first pressure plate, which is attached to the second vibration isolation support. The above arrangement makes the connection between the first plate and the second vibration isolation support relatively tight, the connection area is large, and the force is relatively sufficient, so the first plate can better restrict the deformation of the second vibration isolation support.

[0022] Preferably, the first vibration isolation support, the connecting part, and the second vibration isolation support form a first accommodating space, and at least two reinforcing members are located within the first accommodating space and are connected between the first vibration isolation support and the second vibration isolation support.

[0023] And / or, the second vibration isolation support and at least two reinforcing members form a second receiving space, and the bending load-bearing member is located within the second receiving space.

[0024] In this design, at least two reinforcing members are located within the first accommodating space and connected between the first vibration isolation support and the second vibration isolation support. This arrangement makes the components of the suspension device more compact, saving space. Due to the compact position of the components of the suspension device, the load-bearing capacity of the suspension device is stronger and more stable. In addition, the second vibration isolation support and at least two reinforcing members form the second accommodating space, and the bending load-bearing member is located within the second accommodating space, further making the components of the suspension device more compact, saving space, and also making the bending load-bearing member more stable and less prone to falling off.

[0025] Preferably, there are two reinforcing members, and both reinforcing members have through holes;

[0026] In this case, for any reinforcing member, the through holes are configured such that the stiffness of the reinforcing member gradually decreases in the front-rear direction of the cylinder.

[0027] In this design, since the center of gravity of the cylinder is at the front and the weight at the front is large, the above-mentioned arrangement makes the elastic support component at the front of the cylinder have high stiffness and can bear a large weight, preventing the front of the cylinder from sinking during installation, which would increase the tensile stress on the front door seal and make the door seal easy to damage. Moreover, the weight at the rear of the cylinder is small, and the corresponding suspension device has low stiffness, resulting in good vibration isolation effect. In addition, both reinforcing members have through holes, which can further improve the vibration isolation effect of the suspension device.

[0028] Preferably, the through hole is a trapezoidal through hole, with the long side of the trapezoidal through hole located at the front of the cylinder and the short side of the trapezoidal through hole located at the rear of the cylinder in the front-back direction.

[0029] In this design, the longer side of the trapezoidal through-hole is located at the front of the cylinder, and the shorter side is located at the rear. This means the area of ​​the through-hole supporting the front of the cylinder is smaller than the area supporting the rear, and the supporting area at the front is larger than the supporting area at the rear. This arrangement prevents the front of the cylinder from sinking during installation, which would increase the tensile stress on the front door seal and make it more susceptible to damage. Furthermore, by using the trapezoidal through-hole, the stiffness variation in the front-to-back direction of the cylinder can be achieved with a relatively simple structure, which helps simplify the structure of the suspension device.

[0030] Preferably, the first bracket includes a first mounting plate and a crossbeam, the two ends of which are used to be mounted on the casing of the washing machine, and the first end of the elastic support assembly is located between the first mounting plate and the crossbeam; wherein the first mounting plate has a first mounting hole, and a reinforcing member is a first reinforcing member, the first end of which passes through the first mounting hole and is connected to the first end of the elastic support assembly.

[0031] In this design, the first end of the elastic support component is located between the first mounting plate and the crossbeam, so that the elastic support component is stably installed on the housing. In addition, the first end of the first reinforcing member passes through the first mounting hole and is connected to the first end of the elastic support component. The above arrangement makes the first reinforcing member also restricted by the first mounting hole, so it is not easy to deform and is not easy to detach from the elastic support component.

[0032] Preferably, the second bracket includes a second mounting plate and a mounting member, and the second end of the elastic support assembly is located between the second mounting plate and the mounting member; the second mounting plate is used to thread the second end of the elastic support assembly onto the mounting member, and the mounting member is used to be mounted on the outer peripheral wall of the cylinder;

[0033] Wherein, along the extending direction of the elastic support assembly, the second end of the first reinforcing member is connected to the end face of the second end of the elastic support assembly near the end of the second end of the elastic support assembly, and the connection position between the second end of the first reinforcing member and the second end of the elastic support assembly is located above the second mounting plate; or,

[0034] The second mounting plate has a second mounting hole, and the second end of the first reinforcing member passes through the second mounting hole and is connected to the second end of the elastic support assembly.

[0035] In this design, the second end of the elastic support assembly is located between the second mounting plate and the mounting member. The second mounting plate is used to thread the second end of the elastic support assembly onto the mounting member, and the mounting member is used to install it onto the outer peripheral wall of the cylinder. This arrangement allows the elastic support assembly to be stably installed on the cylinder. Furthermore, the connection position between the second end of the first reinforcing member and the second end of the elastic support assembly is located above the second mounting plate, so that the effective range of the first reinforcing member is larger and the range of stiffness reinforcement of the suspension device is larger.

[0036] The second mounting plate has a second mounting hole, and the second end of the first reinforcing member passes through the second mounting hole and is connected to the second end of the elastic support assembly. The above arrangement makes the second end of the first reinforcing member restricted by the second mounting hole, so that it is not easy to deform and is not easy to detach from the elastic support assembly.

[0037] Preferably, the reinforcement is made of an elastic material, and the reinforcement and the elastic support assembly can be integrally formed.

[0038] In this design, the reinforcing member is made of elastic material. This design increases the stiffness of the suspension device without making the stiffness too large and affecting the vibration isolation effect. In addition, the one-piece design saves space occupied by the suspension device. Furthermore, the one-piece component is generally not easily damaged or broken into several parts when subjected to gravity, and it is also easy to process.

[0039] This utility model also provides a washing machine, which includes a cabinet, a drum, and the aforementioned suspension device; wherein, there are multiple drums, each of which is suspended from the cabinet by the suspension device; or, there are multiple drums, adjacent drums are connected to each other, and the two drums at both ends are suspended from the cabinet by the suspension device.

[0040] In this design, adjacent cylinders are interconnected, and both cylinders at both ends are suspended from the box body by a suspension device, meaning that the suspension device can withstand a large amount of gravity.

[0041] The positive and progressive effects of this utility model are as follows: the elastic support component is beneficial for supporting and buffering the drum; the anti-bending load-bearing component can convert the bending of the second end of the elastic support component into a compressive load on the second end of the elastic support component, thereby improving the anti-bending load-bearing capacity of the second end of the elastic support component and preventing excessive deformation of the elastic support component on the load-bearing side of the washing machine, thus losing its load-bearing function; in addition, the second end of the elastic support component is closer to or further away from the first end of the drum due to changes in gravity. The above arrangement can support the drum when it becomes heavier and has a good vibration isolation effect when it becomes lighter; at least one reinforcing member has a through hole, and the area of ​​the through hole is not less than half the area of ​​the reinforcing member, making the reinforcing member lighter and increasing the stiffness by a limited amount, thus preventing poor vibration isolation effect of the suspension device. Moreover, since the stiffness increase of a single reinforcing member is limited, setting at least two reinforcing members can compensate for the required stiffness, increase the load-bearing capacity of the suspension device, prevent the front of the drum from sinking in the installed state, which would lead to increased tensile stress on the front door seal and easy damage to the door seal, and maintain a good vibration isolation effect of the suspension device.

[0066] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0067] 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.

[0068] like Figure 1-4As shown, this embodiment provides a suspension device 100 for suspending the drum 400 of a washing machine 200 from the casing 300 of the washing machine 200. The suspension device 100 includes: a first bracket 1, a second bracket 2, an elastic support assembly 3, a bending-resistant load-bearing member 4, and at least two reinforcing members (please refer to the first reinforcing member 5 and the second reinforcing member 6 below); the first end of the first bracket 1 is used to connect to the casing 300; the first end of the second bracket 2 is used to connect to the drum 400; the first end of the elastic support assembly 3 is connected to the second end of the first bracket 1, and the second end of the elastic support assembly 3 is connected to the second end of the second bracket 2. The deformation at one end is configured to change with the gravity of the cylinder 400, moving closer to or further away from the first end of the elastic support assembly 3; a bending bearing member 4 is disposed at the second end of the elastic support assembly 3, wherein the bending bearing member 4 is configured to act on the elastic support assembly 3 and compress the second end of the elastic support assembly 3 when the elastic support assembly 3 deforms; a reinforcing member acts on the second end of the elastic support assembly 3 to provide a force to the second end of the elastic support assembly 3 in the opposite direction to the deformation of the first end of the elastic support assembly 3, and at least one of the reinforcing members has a through hole 7, and the area of ​​the through hole 7 is not less than half the area of ​​the reinforcing member.

[0069] In this embodiment, the elastic support component 3 provides support and cushioning for the drum 400. The bending-resistant bearing component 4 converts the bending of the second end of the elastic support component 3 into a compressive load on the second end of the elastic support component 3, thereby improving the bending-resistant bearing capacity of the second end of the elastic support component 3. This helps prevent excessive deformation of the elastic support component 3 on the bearing side of the washing machine 200, thus preventing it from losing its bearing function. Furthermore, the second end of the elastic support component 3 moves closer to or further away from the first end of the drum 400 as the weight changes. The above arrangement can support the drum 400 when it becomes heavier. It can achieve a good vibration isolation effect when the cylinder 400 becomes lighter; at least one reinforcing member has a through hole 7, and the area of ​​the through hole 7 is not less than half the area of ​​the reinforcing member, so that the weight of the reinforcing member is lighter and the increase in stiffness is limited, so as to prevent the suspension device 100 from having a poor vibration isolation effect. Moreover, since the increase in stiffness of a single reinforcing member is limited, setting at least two reinforcing members can compensate for the required stiffness, increase the load-bearing capacity of the suspension device 100, prevent the front of the cylinder 400 from sinking in the installed state, which would lead to an increase in the tensile stress of the front door seal and the door seal being easily damaged, and also make the suspension device 100 maintain a good vibration isolation effect.

[0070] It should be noted that when the washing machine 200 is in the washing mode, the drum 400 is very heavy, and the second end of the elastic support component 3 is far away from the first end of the elastic support component 3; when the washing machine 200 is in the washing mode, the drum 400 is light, and the second end of the elastic support component 3 is closer to the first end of the elastic support component 3 relative to the washing mode; in addition, multiple reinforcing members can also be provided.

[0071] It should also be noted that the first bracket 1 includes a first mounting plate 11 and a crossbeam 12. The two ends of the crossbeam 12 are used to connect to the housing 300. The first end of the elastic support component 3 is located between the crossbeam 12 and the first mounting plate 11. The first mounting plate 11 threadedly connects the elastic support component 3 to the crossbeam 12. In addition, both the first mounting plate 11 and the second mounting plate 21 have a third mounting hole 34 for threaded connection.

[0072] The second bracket 2 includes a second mounting plate 21 and a mounting component 22. The second end of the elastic support component 3 is located between the second mounting plate 21 and the mounting component 22. The second mounting plate 21 is used to thread the second end of the elastic support component 3 onto the mounting component 22. The mounting component 22 is installed on the outer peripheral wall of the cylinder 400.

[0073] like Figure 2 and Figure 4 As shown, the elastic support assembly 3 includes a first vibration isolation support part 31, a connecting part 33, and a second vibration isolation support part 32 connected end to end. The first vibration isolation support part 31, the connecting part 33, and the second vibration isolation support part 32 are made of elastic material. The first vibration isolation support part 31 is connected to the first bracket 1, and the second vibration isolation support part 32 is connected to the second bracket 2.

[0074] Among them, the bending bearing member 4 is disposed in the second vibration isolation support 32 on the side facing the first vibration isolation support 31.

[0075] In this embodiment, the elastic support assembly 3 includes a first vibration isolation support 31, a connecting part 33, and a second vibration isolation support 32 made of elastic material. This arrangement helps to reduce the vibration transmitted from the cylinder 400 to the box 300 and can provide flexible buffering for the vibration of the cylinder 400. In addition, the position of the bending bearing member 4 can first prevent the second vibration isolation support 32 from deforming too much, and then prevent the first vibration isolation support 31 and the connecting part 33 from deforming too much. If the bending bearing member 4 is provided on the first vibration isolation support 31 or the connecting part 33, the second vibration isolation support 32 will still easily deform too much on the bearing side of the cylinder 400.

[0076] It should be noted that the bending bearing member 4 can cover the entire side of the second vibration isolation support 32; in addition, the bending bearing member 4 can also be provided on the side of the first vibration isolation support 31 facing the second vibration isolation support 32; the bending bearing member 4 applies force in the opposite direction to the deformation direction of the second vibration isolation support 32.

[0077] like Figure 2 As shown, the second vibration isolation support 32 has a first end connected to the second bracket 2 and a second end away from the second bracket 2 along the extending direction. Along the extending direction of the second vibration isolation support 32, the bending bearing member 4 includes a first pressure plate, which is attached to the second vibration isolation support 32 to press the second vibration isolation support 32 from the side.

[0078] In this embodiment, along the extending direction of the second vibration isolation support 32, the bending bearing member 4 includes a first pressure plate. The first pressure plate is attached to the second vibration isolation support 32. The above arrangement makes the connection between the first plate and the second vibration isolation support 32 relatively tight, the connection area is large, and the force is relatively sufficient. The first plate can also better restrict the deformation of the second vibration isolation support 32.

[0079] It should be noted that the first pressure plate and the second bracket 2 can be made as a single piece.

[0080] like Figure 2 As shown, the first vibration isolation support 31, the connecting part 33 and the second vibration isolation support 32 form a first accommodating space, and at least two reinforcing members are located in the first accommodating space and are connected between the first vibration isolation support 31 and the second vibration isolation support 32.

[0081] And / or, the second vibration isolation support 32 and at least two reinforcing members form a second receiving space, and the bending load-bearing member 4 is located within the second receiving space. In this embodiment, at least two reinforcing members are located within the first receiving space and connected between the first vibration isolation support 31 and the second vibration isolation support 32. This arrangement makes the positions of the components of the suspension device 100 more compact, saving space. Because the positions of the components of the suspension device 100 are more compact, the load-bearing capacity of the suspension device 100 is stronger and more stable. In addition, the second vibration isolation support 32 and at least two reinforcing members form a second receiving space, and the bending load-bearing member 4 is located within the second receiving space, which further makes the positions of the components of the suspension device 100 more compact, saving space, and also makes the bending load-bearing member 4 more stable and less prone to falling off.

[0082] It should be noted that the reinforcing member can be a rubber part; in addition, the second receiving space is inside the first receiving space.

[0083] like Figure 4 As shown, there are two reinforcing members, and both reinforcing members have through holes 7;

[0084] In this case, for any reinforcing member, the through hole 7 is configured such that the stiffness of the reinforcing member gradually decreases in the front-rear direction of the cylinder 400.

[0085] In this embodiment, since the center of gravity of the cylinder 400 is at the front and the front part is heavy, the above-mentioned arrangement makes the elastic support component 3 have high stiffness at the front of the cylinder 400 and bear a large weight, preventing the front of the cylinder 400 from sinking in the installed state, which would increase the tensile stress on the front door seal and make the door seal easy to be damaged. Moreover, the rear part of the cylinder 400 has low gravity, and the corresponding suspension device 100 has low stiffness and good vibration isolation effect. In addition, both reinforcing members have through holes 7 to improve the vibration isolation effect of the suspension device 100.

[0086] It should be noted that the two reinforcing members and the elastic support component 3 form a triangular structure, which is relatively stable.

[0087] like Figure 1 and Figure 4 As shown, the through hole 7 is a trapezoidal through hole 7. In the front-rear direction of the cylinder 400, the long side of the trapezoidal through hole 7 is located in front of the cylinder 400, and the short side of the trapezoidal through hole 7 is located in rear of the cylinder 400.

[0088] In this embodiment, the long side of the trapezoidal through hole 7 is located in front of the cylinder 400, and the short side of the trapezoidal through hole 7 is located in rear of the cylinder 400. That is to say, the area of ​​the through hole 7 in front of the reinforcing member supporting the cylinder 400 is smaller than the area of ​​the through hole 7 in rear of the cylinder 400. In other words, the supporting area in front of the reinforcing member supporting the cylinder 400 is larger than the supporting area in rear of the cylinder 400. The above arrangement prevents the front of the cylinder 400 from sinking in the installed state, which would increase the tensile stress on the front door seal and make the door seal easy to be damaged.

[0089] It should be noted that the positions of the short and long sides of the trapezoidal through hole 7 can be set according to the position of the center of gravity of different cylinders 400, so that the short side of the trapezoidal through hole 7 supports the center position of the cylinder 400.

[0090] The first mounting plate 11 has a first mounting hole, and a reinforcing member is a first reinforcing member 5. The first end of the first reinforcing member 5 passes through the first mounting hole and is connected to the first end of the elastic support assembly 3.

[0091] In this embodiment, the first end of the elastic support component 3 is located between the first mounting plate 11 and the crossbeam 12, so that the elastic support component 3 is stably installed on the housing 300; in addition, the first end of the first reinforcing member 5 passes through the first mounting hole and is connected to the first end of the elastic support component 3. The above arrangement makes the first reinforcing member 5 also restricted by the first mounting hole, so that it is not easy to deform and is not easy to detach from the elastic support component 3.

[0092] It should be noted that when there are two reinforcing members, one of the reinforcing members is the second reinforcing member 6. The second reinforcing member 6 is connected between the first vibration isolation support 31 and the second vibration isolation support 32. The first end of the second reinforcing member 6 is located below the first bracket 1 and abuts against the first bracket 1. The second end of the second reinforcing member 6 is located below the bending load-bearing member 4 and abuts against the bending load-bearing member 4.

[0093] like Figure 1-2 As shown, the second bracket 2 includes a second mounting plate 21 and a mounting member 22. The second end of the elastic support assembly 3 is located between the second mounting plate 21 and the mounting member 22. The second mounting plate 21 is used to thread the second end of the elastic support assembly 3 onto the mounting member 22. The mounting member 22 is used to install on the outer peripheral wall of the cylinder 400.

[0094] Wherein, along the extending direction of the elastic support component 3, the second end of the first reinforcing member 5 is connected to the end face of the second end of the elastic support component 3 near the end face of the second end of the elastic support component 3, and the connection position between the second end of the first reinforcing member 5 and the second end of the elastic support component 3 is located above the second mounting plate 21; or,

[0095] The second mounting plate 21 has a second mounting hole, and the second end of the first reinforcing member 5 passes through the second mounting hole and is connected to the second end of the elastic support assembly 3.

[0096] In this embodiment, the second end of the elastic support component 3 is located between the second mounting plate 21 and the mounting member 22. The second mounting plate 21 is used to thread the second end of the elastic support component 3 onto the mounting member 22, and the mounting member 22 is used to install on the outer peripheral wall of the cylinder 400. The above arrangement enables the elastic support component 3 to be stably installed on the cylinder 400. In addition, the connection position between the second end of the first reinforcing member 5 and the second end of the elastic support component 3 is located above the second mounting plate 21, so that the effective range of the first reinforcing member 5 is larger and the range of stiffness reinforcement of the suspension device 100 is larger.

[0097] The second mounting plate 21 has a second mounting hole, and the second end of the first reinforcing member 5 passes through the second mounting hole and is connected to the second end of the elastic support assembly 3. The above arrangement makes the second end of the first reinforcing member 5 restricted by the second mounting hole, so that it is not easy to deform and is not easy to detach from the elastic support assembly 3.

[0098] like Figure 4 As shown, the reinforcing member is made of elastic material, and the reinforcing member and the elastic support component 3 can be integrally molded.

[0099] In this embodiment, the reinforcing member is made of an elastic material. This arrangement increases the stiffness of the suspension device 100 without making the stiffness of the suspension device 100 too large and affecting the vibration isolation effect. In addition, the above-mentioned one-piece design saves the space occupied by the suspension device 100. Furthermore, the one-piece component is generally not easily damaged or broken into several parts when subjected to gravity, and it is also convenient to process.

[0100] This utility model also provides a washing machine 200, which includes a cabinet 300, a drum 400 and the aforementioned suspension device 100; wherein, there are multiple drums 400, and each drum 400 is suspended from the cabinet 300 by the suspension device 100; or, there are multiple drums 400, adjacent drums 400 are connected to each other, and the two drums 400 at both ends are suspended from the cabinet 300 by the suspension device 100.

[0101] In this embodiment, adjacent cylinders 400 are connected to each other, and both cylinders 400 at both ends are suspended from the box 300 by the suspension device 100, which means that the suspension device 100 can withstand a large amount of gravity.

[0102] In this embodiment, as shown in the figure, the washing machine 200 has two drums 400 connected together, and each drum 400 is suspended from the housing 300 by a suspension device 100. Specifically, the sidewalls of the drums 400 are suspended from the inner wall of the housing 300 by the suspension device 100.

[0103] In other embodiments, the washing machine 200 may have three or more drums 400; adjacent drums 400 are connected to each other, and the two drums 400 at both ends are suspended from the cabinet 300 by the suspension device 100, that is to say, the suspension device 100 can withstand a large amount of gravity.

[0104] 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.
