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 washing machine in the prior art, which easily leads to excessive deformation on the vibration isolation bearing side and loss of bearing function, and to provide a suspension device and a washing machine including the device.

[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, wherein a first end of the elastic support assembly is connected to a second end of a first bracket, and a second end of the elastic support assembly is connected to a second end of a second bracket; and

[0014] A bending load-bearing component is installed at the second end of the elastic support assembly;

[0015] The deformation of the second end of the elastic support assembly is configured to change with the decrease or increase of the weight of the cylinder, so as to move closer to or further away from the first end of the elastic support assembly.

[0016] The bending 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.

[0017] In this design, the elastic support component helps to support and buffer the drum, while the 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 bending load-bearing capacity of the second end of the elastic support component. This helps to prevent the elastic support component on the load-bearing side of the washing machine from deforming too much and 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 design can support the drum when it becomes heavier and has a good vibration isolation effect when the drum becomes lighter.

[0018] 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 in sequence. 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.

[0019] The bending bearing member is located on the side of the second vibration isolation support facing the first vibration isolation support.

[0020] In this solution, 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 can provide flexible buffering for the vibration of the cylinder. In addition, the placement of the bending load-bearing member can first prevent the second vibration isolation support from deforming too much, and then prevent the first vibration isolation support and the connecting part from deforming too much. 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 too much on the bearing side of the cylinder.

[0021] 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.

[0022] And / or,

[0023] The bending load-bearing component includes a second pressure plate. The second vibration isolation support has a vibration isolation support body and a bending moment load-bearing part. The two ends of the vibration isolation support body are respectively used to connect the second bracket and the connecting part. The bending moment load-bearing part is disposed on the side of the vibration isolation support body facing the first vibration isolation support. The second pressure plate extends from the side wall of the vibration isolation support body toward the direction close to the first vibration isolation support, and the second pressure plate presses on the bending moment load-bearing part to squeeze the bending moment load-bearing part from top to bottom.

[0024] In this design, along the extension direction of the second vibration isolation support, the bending load-bearing component includes a first pressure plate, which is attached to the second vibration isolation support. This arrangement ensures a tighter connection between the first plate and the second vibration isolation support, a larger connection area, and sufficient force distribution. The first plate can also better limit the deformation of the second vibration isolation support. Furthermore, the bending moment load-bearing component can improve the stiffness of the elastic support assembly to support a heavier cylinder. The connection between the bending moment load-bearing component and the second plate can also improve the bending resistance of the second vibration isolation support, thus preventing excessive deformation of the second vibration isolation support.

[0025] Preferably, the end of the moment-bearing portion away from the second support extends to the connecting portion.

[0026] In this solution, the above-mentioned configuration can increase the stiffness of the moment-bearing part, thereby further improving the stiffness and bending resistance of the elastic support assembly, and also making the connection between the connecting part and the moment-bearing part more stable.

[0027] Preferably, the thickness of the first vibration isolation support is not greater than the thickness of the vibration isolation support body.

[0028] In this scheme, the above-mentioned settings can, on the one hand, increase the stiffness of the elastic support component to increase its load-bearing capacity, and on the other hand, make the stiffness of the elastic support component less high to provide a relatively good vibration isolation effect.

[0029] Preferably, the second bracket includes a second mounting plate and a mounting member, with the second end of the elastic support assembly 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.

[0030] In this design, the second end of the elastic support assembly is located between the second mounting plate and the mounting component, which allows the elastic support assembly to be stably installed on the cylinder.

[0031] Preferably, the second bracket includes a second mounting plate and a mounting component, and the second end of the elastic support assembly is located between the second mounting plate and the mounting component; the second mounting plate is used to thread the second end of the elastic support assembly onto the mounting component, and the mounting component is mounted on the outer peripheral wall of the cylinder;

[0032] The first pressure plate and the second mounting plate can be integrally formed, or the second pressure plate and the second mounting plate can be integrally formed.

[0033] In this solution, the aforementioned one-piece molding design saves space occupied by the suspension device; in addition, the one-piece molding component is generally not easily damaged or broken into several parts when subjected to gravity.

[0034] Preferably, the connection portion is configured to be selected from any of the following configurations:

[0035] (1) The connecting part is configured such that the distance between the first vibration isolation support part and the second vibration isolation support part gradually increases or gradually decreases in the front-rear direction of the cylinder;

[0036] (2) The connecting part is configured such that the thickness gradually increases or decreases in the front-rear direction of the cylinder;

[0037] (3) In the front-rear direction of the cylinder, the distance between the first vibration isolation support and the second vibration isolation support gradually decreases, and the connecting part is configured such that the thickness of the connecting part gradually increases in the front-rear direction of the cylinder.

[0038] (4) In the front-rear direction of the cylinder, the distance between the first vibration isolation support and the second vibration isolation support gradually increases, and the connecting part is configured such that the thickness of the connecting part gradually decreases in the front-rear direction of the cylinder.

[0039] In this scheme, the above (1) setting method can be based on the fact that when the center of gravity of the cylinder is in front of the cylinder, the distance between the first vibration isolation support and the second vibration isolation support gradually increases, so that the elastic support component has a large stiffness and a large load-bearing capacity in front of the cylinder, preventing the front of the cylinder from sinking in the installation state, which would increase the tensile stress of the front door seal and make the door seal easy to be damaged. Moreover, the weight of the rear of the cylinder is small, and the corresponding distance between the first vibration isolation support and the second vibration isolation support is large, resulting in a good vibration isolation effect. Similarly, when the center of gravity of the cylinder is in the rear of the cylinder, the distance between the first vibration isolation support and the second vibration isolation support gradually decreases, so that the elastic support component has a large stiffness and a large load-bearing capacity in the rear of the cylinder, preventing the rear of the cylinder from sinking in the installation state, which would increase the tensile stress of the front door seal and make the door seal easy to be damaged. Moreover, the weight of the front of the cylinder is small, and the corresponding distance between the first vibration isolation support and the second vibration isolation support is large, resulting in a good vibration isolation effect. In other words, the above (1) setting method can be applied to cylinders with different center of gravity positions, achieving both good vibration isolation effect and good load-bearing effect.

[0040] The above (2) configuration makes the stiffness of the elastic support component different in different parts, so as to increase the overall stiffness variation range of the elastic support component to cope with different working states of the cylinder; in addition, when the center of gravity of the cylinder is in front of the cylinder, the connecting part is configured to gradually decrease in thickness in the front-rear direction of the cylinder, and when the center of gravity of the cylinder is in the rear of the cylinder, the connecting part is configured to gradually increase in thickness in the front-rear direction of the cylinder. The configuration of gradually increasing or decreasing thickness of the connecting part can also control the distance between the first vibration isolation support part and the second vibration isolation support part to achieve the effect in the above (1);

[0041] The above-mentioned (3) and (4) settings simultaneously increase or decrease the distance between the first vibration isolation support and the second vibration isolation support, as well as the thickness of the connecting part, so as to flexibly target the cylinder at different center of gravity positions, and achieve both good vibration isolation effect and good load-bearing effect.

[0042] This utility model also includes a washing machine, which comprises a cabinet, a drum, and the aforementioned suspension device.

[0043] Preferably, there are multiple cylinders, each of which is suspended from the box by a suspension device; or,

[0044] There are multiple cylinders, and adjacent cylinders are connected to each other. The two cylinders at both ends are suspended from the box by a suspension device.

[0045] 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.

[0046] The positive and progressive effects of this utility model are as follows: the setting of the elastic support component is conducive to supporting and buffering the drum body; the setting of the bending bearing member 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 by the bending bearing member, thereby improving the bending bearing capacity of the second end of the elastic support component and preventing the elastic support component on the bearing side of the washing machine from deforming too much and losing its 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 body when the weight changes, so as to achieve both the ability to support the drum body when the drum body becomes heavier and to have a better vibration isolation effect when the drum body becomes lighter.

[0070] 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.

[0071] like Figure 1-4 As 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, the first end of which is connected to the casing 300; a second bracket 2, the first end of which is connected to the drum 400; an elastic support assembly 3, the first end of which is connected to the second end of the first bracket 1, and the second end of which is connected to the second end of the second bracket 2; and a bending-resistant bearing member 4, disposed at the second end of the elastic support assembly 3. The deformation of the second end of the elastic support assembly 3 is configured to change with the decrease or increase of the weight of the drum 400, so as to move closer to or further away from the first end of the elastic support assembly 3. The bending-resistant 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.

[0072] In this embodiment, the elastic support component is beneficial for supporting and buffering the drum 400. The bending support member 4 can convert 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 by the bending support member 4, thereby improving the bending load capacity of the second end of the elastic support component 3. This helps to prevent the elastic support component 3 on the bearing side of the washing machine 200 from deforming too much and losing its bearing function. In addition, the second end of the elastic support component 3 is closer to or further away from the first end of the drum 400 due to gravity changes. The above arrangement can support the drum 400 when it becomes heavier and has a good vibration isolation effect when the drum 400 becomes lighter.

[0073] 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.

[0074] like Figure 1-4As 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 in sequence. 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.

[0075] 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.

[0076] 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 is beneficial for reducing the vibration transmitted from the cylinder 400 to the box 300 and for providing flexible buffering of 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 deform too much on the bearing side of the cylinder 400.

[0077] 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.

[0078] According to different setup requirements, the bending support member can be set as follows: 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 extension direction. Along the extension direction of the second vibration isolation support 32, the bending support member 4 includes a first pressure plate. The first pressure plate is attached to the second vibration isolation support 32 to press the second vibration isolation support 32 from the side.

[0079] And / or,

[0080] The bending load-bearing member 4 includes a second pressure plate. The second vibration isolation support part 32 has a vibration isolation support body 321 and a bending moment bearing part 322. The two ends of the vibration isolation support body 321 are respectively used to connect the second bracket 2 and the connecting part 33. The bending moment bearing part 322 is disposed on the side of the vibration isolation support body 321 facing the first vibration isolation support part 31. The second pressure plate extends from the side wall of the vibration isolation support body 321 toward the direction close to the first vibration isolation support part 31, and the second pressure plate presses on the bending moment bearing part 322 to squeeze the bending moment bearing part 322 from top to bottom.

[0081] Along the extension 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. This arrangement ensures a tighter connection between the first plate and the second vibration isolation support 32, a larger connection area, and sufficient force distribution, thus better limiting the deformation of the second vibration isolation support 32. Furthermore, the bending moment bearing member 322 increases the stiffness of the elastic support assembly 3 to support the heavier cylinder 400. The connection between the bending moment bearing member 322 and the second plate also improves the bending resistance of the second vibration isolation support 32, preventing excessive deformation. Additionally, the bending moment bearing member 322 effectively increases the thickness of the vibration isolation support body 321. In the installed state, the compressive load of the second pressure plate on the bending moment bearing member 322 converts the bending of the bending moment bearing member 322 into a compressive load on the area, thereby improving the bending resistance of the bending moment bearing member 322 and mitigating the problem of excessive deformation of the second vibration isolation support 32.

[0082] Specifically, in this embodiment, such as Figure 1-4 As shown, the bending support member 4 includes the aforementioned second pressure plate, i.e., the latter arrangement is adopted. In other alternative embodiments, the bending support member 4 may also include the aforementioned first pressure plate, or simultaneously include both the first pressure plate and the second pressure plate.

[0083] It should be noted that the moment bearing part 322 is equivalent to thickening the vibration isolation support body 321 to increase the stiffness of the second vibration isolation support part 32. In addition, the thickened second vibration isolation support part 32 is closer to the first vibration isolation support part 31, further increasing the overall stiffness of the elastic support assembly 3.

[0084] As a preferred configuration, the end of the moment-bearing portion 322 away from the second support 2 extends to the connecting portion 33.

[0085] In this embodiment, the above-mentioned arrangement can increase the stiffness of the moment-bearing part 322, thereby further improving the stiffness and bending resistance of the elastic support assembly 3, and also making the connection between the connecting part 33 and the moment-bearing part 322 more stable.

[0086] It should be noted that setting the moment bearing part 322 to extend to the entire elastic support component 3 is not a preferred setting, because this would make the entire elastic support component 3 too stiff and the vibration isolation effect poor.

[0087] like Figure 4 As shown, the thickness of the first vibration isolation support 31 is not greater than the thickness of the vibration isolation support body 321.

[0088] In this embodiment, the above-mentioned arrangement can, on the one hand, increase the stiffness of the elastic support component 3 so as to increase the load-bearing weight of the elastic support component 3, and on the other hand, make the stiffness of the elastic support component 3 not so high so as to provide a relatively good vibration isolation effect.

[0089] It should be noted that the first vibration isolation support 31 belongs to the low stiffness deformation bearing area.

[0090] like Figure 1-4 As shown, the second bracket 2 includes a second mounting plate 21 and a mounting member 22. 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. The mounting member 22 is used to install on the outer peripheral wall of the cylinder 400.

[0091] 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. This arrangement enables the elastic support component 3 to be stably installed on the cylinder 400.

[0092] It should 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 mounting holes 34 for threaded connection.

[0093] like Figure 3 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 installed on the outer peripheral wall of the cylinder 400.

[0094] The first pressure plate and the second mounting plate 21 can be integrally formed, or the second pressure plate and the second mounting plate 21 can be integrally formed.

[0095] In this embodiment, the one-piece design saves space occupied by the suspension device 100; in addition, the one-piece component is generally not easily damaged or broken into several parts when subjected to gravity.

[0096] like Figure 1-4 As shown, the connection part 33 is configured to be selected from any of the following configurations:

[0097] (1) The connecting part 33 is configured such that the distance between the first vibration isolation support part 31 and the second vibration isolation support part 32 gradually increases or gradually decreases in the front-rear direction of the cylinder 400.

[0098] (2) The connecting part 33 is configured such that its thickness gradually increases or decreases in the front-rear direction of the cylinder 400;

[0099] (3) In the front-rear direction of the cylinder, the distance between the first vibration isolation support 31 and the second vibration isolation support 32 gradually decreases, and the connecting part 33 is configured such that the thickness of the cylinder 400 gradually increases in the front-rear direction.

[0100] (4) In the front-rear direction of the cylinder, the distance between the first vibration isolation support 31 and the second vibration isolation support 32 gradually increases, and the connecting part 33 is configured such that the thickness of the cylinder 400 gradually decreases in the front-rear direction.

[0101] In this embodiment, the arrangement of (1) above can be based on the fact that when the center of gravity of the cylinder 400 is in front of the cylinder 400, the distance between the first vibration isolation support 31 and the second vibration isolation support 32 gradually increases, so that the elastic support assembly 3 has high rigidity and large load-bearing capacity at the front of the cylinder 400, 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 of the cylinder 400 has low gravity, and the corresponding distance between the first vibration isolation support 31 and the second vibration isolation support 32 is large, resulting in good vibration isolation effect. Similarly, when the center of gravity of the cylinder 400 is in front of the cylinder 400, the distance between the first vibration isolation support 31 and the second vibration isolation support 32 is large, resulting in good vibration isolation effect. When the cylinder 400 is in the rear, the distance between the first vibration isolation support 31 and the second vibration isolation support 32 gradually decreases, so that the elastic support assembly 3 has a large stiffness at the rear of the cylinder 400 and a large load-bearing capacity, preventing the rear of the cylinder 400 from sinking in the installation state, which would increase the tensile stress of the front door seal and make the door seal easy to be damaged. Moreover, the front of the cylinder 400 has a small weight, and the distance between the first vibration isolation support 31 and the second vibration isolation support 32 is large, resulting in a good vibration isolation effect. In other words, the above (1) setting method can be applied to cylinders 400 at different center of gravity positions, achieving both good vibration isolation effect and good load-bearing effect.

[0102] The above-mentioned (2) configuration makes the stiffness of the elastic support component 3 different in different parts, so as to increase the overall stiffness variation range of the elastic support component 3 to cope with different working states of the cylinder 400. In addition, when the center of gravity of the cylinder 400 is in front of the cylinder 400, the connecting part 33 is configured to gradually decrease in thickness in the front-rear direction of the cylinder 400, and when the center of gravity of the cylinder 400 is behind the cylinder 400, the connecting part 33 is configured to gradually increase in thickness in the front-rear direction of the cylinder 400. The configuration of gradually increasing or decreasing thickness of the connecting part 33 can also control the distance between the first vibration isolation support part 31 and the second vibration isolation support part 32 to achieve the effect mentioned above (1).

[0103] It should be noted that in the above (2), the stiffness is gradually increased from back to front or from front to back by the gradual change in the thickness of the connecting part 33.

[0104] The above-mentioned (3) and (4) settings simultaneously increase or decrease the distance between the first vibration isolation support and the second vibration isolation support, as well as the thickness of the connecting part, so as to flexibly target the cylinder at different center of gravity positions, and achieve both good vibration isolation effect and good load-bearing effect.

[0105] Specifically, in this embodiment, such as Figures 1-4 As shown, the third configuration is adopted, in which the distance between the first vibration isolation support 31 and the second vibration isolation support 32 gradually decreases, and the connecting part 33 is configured such that the thickness of the connecting part 33 gradually increases in the front-rear direction of the cylinder 400. As a preferred configuration, this is achieved by rounding the corners of the connecting part 33, with a larger radius of the rounded corner at the rear of the cylinder 400 and a smaller radius of the rounded corner at the front of the cylinder 400.

[0106] This utility model also includes a washing machine 200, which includes a cabinet 300, a drum 400, and the aforementioned hanging device 100.

[0107] There are multiple cylinders 400, each cylinder 400 is suspended from the box 300 by a suspension device 100; or,

[0108] There are multiple cylinders 400, and adjacent cylinders 400 are connected to each other. The two cylinders 400 at both ends are suspended from the box 300 by the suspension device 100.

[0109] In this embodiment, such as Figure 1 As shown, the washing machine 200 has two drums 400 connected together, and each drum 400 is suspended from the cabinet 300 by a suspension device 100. Specifically, the side walls of the drums 400 are suspended from the inner wall of the cabinet 300 by the suspension device 100.

[0110] 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.

[0111] This utility model also has the following advantages:

[0112] 1. The design features a simple and compact suspension structure that integrates vibration isolation (suspender spring function) and vibration attenuation (damper function) into a single component, eliminating the traditional method of suspending the housing 300 with dampers and suspension springs, thus reducing the space occupied by the suspension system in the housing 300.

[0113] 2. Reduce the number of connecting parts to avoid relative movement of traditional hard-connected structural components and eliminate the generation of such vibration and noise sources.

[0114] 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.
