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 finalized, have fixed stiffness and damping parameters, making it impossible to adjust them according to changes in operating conditions and thus failing 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. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of existing washing machine vibration damping structures, such as the inability to dynamically adjust the stiffness and damping parameters and the non-compact structure, and to provide a suspension device and a washing machine including the same.

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

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

[0009] A first support, the first end of which is used to connect to the outer wall of the cylinder;

[0010] A second bracket, the first end of which is used to connect to the inner wall of the housing; and

[0011] An elastic support assembly is provided, 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. The elastic support assembly includes a vibration isolation support unit and a washing support unit made of elastic material. The vibration isolation support unit is connected between the first bracket and the second bracket. The vibration isolation support unit has a first vibration isolation support portion, a middle bending portion and a second vibration isolation support portion along the extending direction. The first vibration isolation support portion and the second vibration isolation support portion are connected to both ends of the middle bending portion, and the first vibration isolation support portion is used to connect to the first bracket and the second vibration isolation support portion is used to connect to the second bracket.

[0012] The washing support unit includes a first washing support and a second washing support respectively disposed on the first vibration isolation support and the second vibration isolation support, with the first washing support located above the second washing support in the height direction;

[0013] The deformation of the elastic support component is configured to change positively with the gravity of the drum, so that the first washing support and the second washing support move closer to or further away from each other in the height direction, switching between a first position state and a second position state.

[0014] When in the first position state, the first washing support part and the second washing support part are separated;

[0015] When in the second position, the first washing support abuts against the second washing support and is supported above the second washing support.

[0016] In this design, the elastic support assembly includes a vibration-damping support unit and a washing support unit made of elastic material. This arrangement helps reduce the vibration transmitted from the drum to the housing and provides flexible buffering for the drum's vibration. The deformation of the elastic support assembly changes positively with the weight of the drum, causing the first washing support to move closer to or further away from the second washing support, switching between a first position and a second position. In other words, the suspension device can flexibly isolate and buffer the drum from changes in its weight. When the deformation of the elastic support component is less than the threshold, the second washing support is in a first position separated from the first washing support, and the first washing support is above the second washing support. At this time, the stiffness of the elastic support component is low, and the drum is only subjected to the buffering and vibration reduction effect of the vibration isolation support unit. When the weight of the drum increases or the center of gravity shifts to a preset position, the deformation of the elastic support component is greater than the threshold. At this time, the first washing support is in a second position abutting against the second washing support, and the first washing support is supported on the second washing support. At this time, the stiffness of the elastic support component is high, and the support effect on the drum is better. The vibration isolation support unit and the washing support unit simultaneously have the buffering and vibration reduction effect on the drum, thereby realizing the dynamic adjustment of the stiffness of the suspension device with the change of the weight of the drum, improving the buffering and vibration reduction effect of the suspension device under different working conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine. The suspension system achieves vibration isolation and reduction through elastic support components, reducing the number of parts and eliminating the need for traditional shock absorbers and suspension springs. This results in a more compact structure, significantly reducing the space occupied by the enclosure and avoiding the relative movement of traditional rigidly connected structural components, thus preventing structural noise generated during component operation. Furthermore, the suspension system includes a washing support unit and a vibration isolation support unit, with the washing support unit positioned on top of the vibration isolation support unit, making the suspension system more compact and saving space.

[0017] Preferably, there are multiple first washing support parts and multiple second washing support parts, and the multiple first washing support parts and multiple second washing support parts are arranged in a one-to-one correspondence;

[0018] And / or, the first washing support has a first arcuate protrusion extending toward the second vibration isolation support, and the second washing support has a second arcuate protrusion extending toward the first vibration isolation support.

[0019] In this design, the one-to-one arrangement of multiple first washing support parts and multiple second washing support parts can further improve the rigidity of the suspension device when it is in the second position, and further improve the gravity that the suspension device can withstand.

[0020] Furthermore, the arrangement of the first and second arc-shaped protrusions can shorten the distance between the first and second washing support parts, improving the efficiency of the suspension device switching from the first position to the second position. In addition, the first and second arc-shaped protrusions can also increase the buffer distance between the first and second washing support parts, improving vibration isolation.

[0021] Preferably, along the width direction perpendicular to the extension direction, the width of the first arcuate protrusion is not less than the width of the first vibration isolation support; and / or,

[0022] Along the width direction perpendicular to the extension direction, the width of the second arc-shaped protrusion is not less than the width of the second vibration isolation support.

[0023] In this design, the widths of the first and second arc-shaped protrusions are designed to increase the contact area between the first and second arc-shaped protrusions when the suspension device is in the second position, thereby improving the stiffness of the suspension device.

[0024] Preferably, the first bracket includes a first mounting member and a first mounting plate. The end of the first vibration isolation support portion away from the middle bending portion is clamped between the first mounting plate and the first mounting member. The first mounting member is used to install on the outer wall surface of the cylinder. The first mounting plate threadedly connects the first vibration isolation support portion to the first mounting member.

[0025] In this solution, the first vibration isolation support is installed through the cooperation of the first mounting component and the first mounting plate. The contact area between the first vibration isolation support and the first mounting component and the first mounting plate is large, making the installation of the first vibration isolation support more stable and convenient.

[0026] Preferably, the second bracket includes a second mounting member and a second mounting plate. One end of the second vibration isolation support portion away from the central bending portion is clamped between the second mounting plate and the second mounting member. The second mounting member is used to install on the inner wall surface of the housing. The second mounting plate threadedly connects the second vibration isolation support portion to the second mounting member.

[0027] In this solution, the second vibration isolation support is installed through the cooperation of the second mounting component and the second mounting plate. The contact area between the second vibration isolation support and the second mounting component and the second mounting plate is large, making the installation of the second vibration isolation support more stable and convenient.

[0028] Preferably, the second bracket further includes a third mounting member for covering the inner wall of the housing. One end of the second mounting member is connected to the third mounting member, and the other end of the second mounting member extends downward at an angle toward the elastic support assembly. The second vibration isolation support is supported on the other end of the second mounting member. The second bracket also includes a support rib that supports the other end of the second mounting member and the third mounting member.

[0029] In this design, the inclusion of the third mounting component increases the contact area with the enclosure, facilitating connection and improving reliability. Furthermore, the support ribs provide reinforcement, enhancing the overall reliability of the second bracket and consequently improving the installation reliability of the elastic support assembly.

[0030] Preferably, in the second position state, the side of the first washing support facing the second vibration isolation support can abut against the second vibration isolation support;

[0031] And / or, in the second position state, the side of the second washing support facing the first vibration isolation support can abut against the first vibration isolation support.

[0032] In this design, as the weight of the drum increases, different degrees of contact can occur in the second position. Correspondingly, the proximity of the second washing support to the first vibration-damping support, and vice versa, also varies. When the weight of the drum reaches a certain level, the washing machine can reach its maximum washing capacity. By using this structural arrangement, and by having the washing support abut against the corresponding vibration-damping support, the vibration reduction and isolation effects are further improved. Furthermore, the contact also limits the displacement of the drum.

[0033] Preferably, the vibration isolation support unit is an integrally molded structure;

[0034] Alternatively, the elastic support component may be a one-piece molded structure.

[0035] 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.

[0036] This utility model also provides a washing machine, which includes a cabinet, a drum, and the aforementioned suspension device.

[0037] Preferably, there are multiple cylinders, adjacent cylinders are connected to each other, and the two cylinders at both ends are suspended in the box by a suspension device;

[0038] The vibration isolation support unit has gaps between any position and the outer wall of the cylinder and the inner wall of the box.

[0039] In this design, adjacent drums are interconnected, and both drums at both ends are suspended from the cabinet via suspension devices. This means that the suspension devices can withstand a large amount of gravity. Furthermore, the vibration isolation support unit has gaps between itself and both the outer wall of the drum and the inner wall of the cabinet, providing a buffer space for the transmission of forces from the drum to the inner wall of the cabinet. This ensures control over the drum's displacement under extreme eccentric displacement during the washing machine's spin-drying process, while also significantly reducing the transmission of vibration to the cabinet side.

[0040] The positive and progressive effects of this utility model are as follows:

[0041] In this application, the elastic support assembly includes a vibration isolation support unit and a washing support unit made of elastic material. This arrangement helps to reduce the vibration transmitted from the drum to the housing and provides flexible buffering of the drum's vibration. The deformation of the elastic support assembly changes positively with the weight of the drum, thereby causing the first washing support part to move closer to or further away from the second washing support part, switching between a first position state and a second position state. In other words, the suspension device can flexibly isolate and buffer the drum's vibration in response to changes in its weight. When the deformation of the elastic support component is less than the threshold, the second washing support is in a first position separated from the first washing support, and the first washing support is above the second washing support. At this time, the stiffness of the elastic support component is low, and the drum is only subjected to the buffering and vibration reduction effect of the vibration isolation support unit. When the weight of the drum increases or the center of gravity shifts to a preset position, the deformation of the elastic support component is greater than the threshold. At this time, the first washing support is in a second position abutting against the second washing support, and the first washing support is supported on the second washing support. At this time, the stiffness of the elastic support component is high, and the support effect on the drum is better. The vibration isolation support unit and the washing support unit simultaneously have the buffering and vibration reduction effect on the drum, thereby realizing the dynamic adjustment of the stiffness of the suspension device with the change of the weight of the drum, improving the buffering and vibration reduction effect of the suspension device under different working conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine. The suspension system achieves vibration isolation and reduction through elastic support components, reducing the number of parts and eliminating the need for traditional shock absorbers and suspension springs. This results in a more compact structure, significantly reducing the space occupied by the enclosure and avoiding the relative movement of traditional rigidly connected structural components, thus preventing structural noise generated during component operation. Furthermore, the suspension system includes a washing support unit and a vibration isolation support unit, with the washing support unit positioned on top of the vibration isolation support unit, making the suspension system more compact and saving space.

[0074] 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.

[0075] like Figures 1 to 8 As shown, this embodiment provides a suspension device 100 and a washing machine 200 including the same. The suspension device 100 is used to suspend the drum 400 of the washing machine 200 inside the casing 300 of the washing machine 200. The suspension device 100 includes: a first bracket 1, the first end of which is used to connect to the outer wall of the drum 400; a second bracket 2, the first end of which is used to connect to the inner wall of the casing 300; and 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 the elastic support assembly 3 is connected to the second end of the first bracket 1. At the second end of the second bracket 2, the elastic support assembly 3 includes a vibration-damping support unit and a washing support unit made of elastic material. The vibration-damping support unit is connected between the first bracket 1 and the second bracket 2. Along its extension direction, the vibration-damping support unit has a first vibration-damping support portion 311, a central bending portion 313, and a second vibration-damping support portion 312. The first vibration-damping support portion 311 and the second vibration-damping support portion 312 are connected to the two ends of the central bending portion 313. The first vibration-damping support portion 311 is used to connect to the first bracket 1, and the second vibration-damping support portion 312 is used to connect to the second bracket 2. The washing support unit includes a first washing support portion 321 and a second washing support portion 322 respectively disposed on the first vibration-damping support portion 311 and the second vibration-damping support portion 312. Along the height direction, the first washing support portion 321 is located above the second washing support portion 322. The deformation of the elastic support assembly 3 is configured to change positively with the gravity of the drum 400, so that the first washing support 321 and the second washing support 322 move closer to or further apart in the height direction, switching between a first position state and a second position state. In the first position state, the first washing support 321 and the second washing support 322 are separated; in the second position state, the first washing support 321 abuts against the second washing support 322 and is supported above the second washing support 322.

[0076] In this embodiment, the elastic support assembly 3 includes a vibration isolation support unit and a washing support unit made of elastic material. This arrangement is beneficial for reducing the vibration transmitted from the drum 400 to the housing 300 and for providing flexible buffering of the vibration of the drum 400.

[0077] The deformation of the elastic support component 3 is configured to change positively with the gravity of the drum 400, thereby allowing the first washing support 321 to move closer to or further away from the second washing support 322, switching between a first position and a second position. In other words, the suspension device can flexibly isolate and buffer the drum 400 in response to gravity changes. When the deformation of the elastic support component 3 is less than a threshold, the second washing support 322 is located in a first position separated from the first washing support 321, with the first washing support 321 positioned above the second washing support 322. At this time, the stiffness of the elastic support component 3 is low, and the drum 400 is only subjected to the buffering and vibration reduction effects of the vibration isolation support unit. When the weight of the drum increases or the center of gravity shifts to a preset position, and the deformation of the elastic support component 3 exceeds a threshold, the first washing support 321 is located at a second position abutting against the second washing support 322, and the first washing support 321 is supported on the second washing support 322. At this time, the elastic support component 3 has higher stiffness and better support for the drum 400. The vibration isolation support unit and the washing support unit simultaneously have buffering and vibration reduction effects on the drum, thereby realizing the dynamic adjustment of the stiffness of the suspension device 100 with the change of the weight of the drum 400, improving the buffering and vibration reduction effect of the suspension device 100 under different working conditions of the washing machine 200, and thus optimizing the vibration isolation rate of the washing machine 200.

[0078] The suspension device 100 achieves vibration isolation and damping effects through the elastic support component 3, reducing the number of parts and eliminating the traditional method of vibration damper and suspension spring. This results in a more compact structure, significantly reducing the space occupied by the housing 300. It also avoids the relative movement of traditional rigidly connected structural components, preventing structural noise generated during component operation. Furthermore, the suspension device 100 includes a washing support unit and a vibration isolation support unit, with the washing support unit mounted on the vibration isolation support unit, making the suspension device 100 more compact and saving space.

[0079] Combination Figures 1 to 8 As shown, the first vibration isolation support portion 311, the middle bending portion 313, and the second vibration isolation support portion 312 of the vibration isolation support unit form a receiving cavity 21, making the vibration isolation support unit as a whole present a U-shaped structure or a similar U-shaped structure. Correspondingly, the second washing support portion 322 and the first washing support portion 321 are located within the aforementioned receiving cavity 21.

[0080] It should be noted that the gravity of the cylinder 400 in this embodiment includes the gravity of the cylinder 400 itself and the gravity of the clothes and water contained inside. When the weight of the clothes and / or water inside the cylinder 400 is different, the gravity of the cylinder 400 is also different. That is to say, the gravity of the cylinder 400 will vary depending on whether the cylinder 400 contains clothes and / or water, and the weight of the clothes and / or water contained therein.

[0081] Additionally, it should be noted that when the hanging device 100 is in the first position, the washing machine 200 can be in spin-drying mode. At this time, most of the water in the drum 400 has been drained or is in the process of being drained, and the overall weight of the drum 400 is lighter. When the hanging device 100 is in the second position, the washing machine 200 can be in washing mode. At this time, the water in the drum 400 has not yet been drained, and the overall weight of the drum 400 is very heavy.

[0082] Furthermore, the material of the elastic support component 3 is rubber. When the degree of contact between the first washing support part 321 and the second washing support part 322 is different, that is, when the degree of compression is different, the stiffness of the suspension device 100 is also different. The greater the degree of contact, the greater the stiffness of the suspension device 100, and vice versa.

[0083] like Figures 1 to 8 As shown, in this embodiment, there is one first washing support 321 and one second washing support 322, with one first washing support 321 and one second washing support 322 being provided respectively.

[0084] In other alternative embodiments, the number of first washing support portions 321 and second washing support portions 322 can be multiple, with multiple first washing support portions 321 and multiple second washing support portions 322 arranged in a one-to-one correspondence. This arrangement can further increase the rigidity of the suspension device 100 when the suspension device 100 is in the second position state, and further increase the gravity that the suspension device 100 can withstand.

[0085] The aforementioned plurality of first washing support portions 321 may be sequentially arranged on the first vibration isolation support portion 311 along the direction from the first end of the elastic support assembly 3 toward the second end of the elastic support assembly 3. Correspondingly, a plurality of second washing support portions 322 may be sequentially arranged on the second vibration isolation support portion 312 along the direction from the first end of the elastic support assembly 3 toward the second end of the elastic support assembly 3.

[0086] The first washing support portion 321 has a first arcuate protrusion extending toward the second vibration isolation support portion 312, and the second washing support portion 322 has a second arcuate protrusion extending toward the first vibration isolation support portion 311.

[0087] Furthermore, the arrangement of the first and second arc-shaped protrusions can shorten the distance between the first washing support 321 and the second washing support 322, improving the efficiency of the suspension device 100 switching from the first position state to the second position state. In addition, the first and second arc-shaped protrusions can also increase the buffer distance between the first washing support 321 and the second washing support 322, improving the vibration isolation effect.

[0088] Furthermore, as a preferred configuration, the width of the first arcuate protrusion is not less than the width of the first vibration isolation support 311 in the width direction perpendicular to the extension direction (with respect to the axial direction of the aforementioned receiving cavity 21); and / or, the width of the second arcuate protrusion is not less than the width of the second vibration isolation support 312 in the width direction perpendicular to the extension direction.

[0089] In this embodiment, the widths of the first arc-shaped protrusion and the second arc-shaped protrusion are both set to increase the contact area of ​​the first arc-shaped protrusion and the second arc-shaped protrusion when the suspension device 100 is in the second position state, so as to improve the rigidity of the suspension device 100.

[0090] It should be noted that, based on actual setup requirements, in a natural state, the first and second arc-shaped protrusions can be as close as possible to each other in the height direction, even if there is a gap between them.

[0091] In this embodiment, the first bracket 1 includes a first mounting member 12 and a first mounting plate 11. The end of the first vibration isolation support 311 away from the middle bending part 313 is clamped between the first mounting plate 11 and the first mounting member 12. The first mounting member 12 is used to be installed on the outer wall surface of the cylinder 400. The first mounting plate 11 threadedly connects the first vibration isolation support 311 to the first mounting member 12.

[0092] In this embodiment, the first vibration isolation support 311 is installed by the cooperation of the first mounting member 12 and the first mounting plate 11. The contact area between the first vibration isolation support 311 and the first mounting member 12 and the first mounting plate 11 is large, making the installation of the first vibration isolation support 311 more stable and convenient.

[0093] As a preferred configuration, the second bracket 2 includes a second mounting member 22 and a second mounting plate 23. One end of the second vibration isolation support 312 away from the middle bending part 313 is clamped between the second mounting plate 23 and the second mounting member 22. The second mounting member 22 is used to be installed on the inner wall surface of the housing 300. The second mounting plate 23 threadedly connects the second vibration isolation support 312 to the second mounting member 22.

[0094] In this embodiment, the second vibration isolation support 312 is installed by the cooperation of the second mounting member 22 and the second mounting plate 23. The contact area between the second vibration isolation support 312 and the second mounting member 22 and the second mounting plate 23 is large, making the installation of the second vibration isolation support 312 more stable and convenient.

[0095] To achieve the connection, the second mounting plate 23 and the first mounting plate 11 are each provided with corresponding mounting holes 35, and the elastic support assembly is threaded onto the first bracket 1 and the second bracket 2 through the mounting holes 35.

[0096] At least as Figures 5 to 7 As shown, the second bracket 2 also includes a third mounting member 24, which is used to cover the inner wall of the housing 300. One end of the second mounting member 22 is connected to the third mounting member 24, and the other end of the second mounting member 22 extends downward at an angle toward the elastic support assembly 3. The second vibration isolation support 312 is supported on the other end of the second mounting member 22. The second bracket 2 also includes a support rib 25 that supports the other end of the second mounting member 22 and the third mounting member 24.

[0097] The third mounting component 24 increases the contact area with the housing 300, facilitating connection and improving reliability. Furthermore, the support rib 25 strengthens the structure, increasing the overall reliability of the second bracket 2 and consequently improving the installation reliability of the elastic support assembly 3.

[0098] The first mounting plate 11 is adapted to the inner surface of the first vibration isolation support 311. The end face of the first mounting member 12 connected to the first vibration isolation support 311 is adapted to the outer surface of the first vibration isolation support 311, and the end face of the first mounting member 12 connected to the cylinder 400 is adapted to the outer wall surface of the cylinder 400.

[0099] In this embodiment, the inner surface of the first mounting plate 11 is adapted to the inner surface of the first vibration isolation support 311, resulting in a large connection area between the first mounting plate 11 and the first vibration isolation mounting part 33, and a relatively stable connection. In addition, the first mounting plate 11 and the first vibration isolation support 311 are also easier to bear force, and the force is more evenly distributed. The limitation of the end face of the first mounting member 12 adapting to the outer wall surface of the cylinder 400 also makes the installation of the suspension device 100 and the cylinder 400 more stable.

[0100] It should be noted that the outer wall surface of the cylinder 400 is arc-shaped, and the end face of the first mounting component 12 connecting the cylinder 400 is also arc-shaped.

[0101] Furthermore, the second mounting plate 23 is adapted to the inner surface of the second vibration isolation support 312.

[0102] In this embodiment, the above-mentioned arrangement results in a large connection area between the second mounting plate 23 and the second vibration isolation support 312, making the connection more stable. In addition, the second mounting plate 23 and the second vibration isolation support 312 are also easier to bear force, and the force is more even.

[0103] Reference Figures 5 to 8 It is understood that, in the second position state, the side of the first washing support 321 facing the second vibration isolation support 312 can abut against the second vibration isolation support 312; and / or, in the second position state, the side of the second washing support 322 facing the first vibration isolation support 311 can abut against the first vibration isolation support 311.

[0104] In this embodiment, as the weight of the drum 400 increases, different degrees of contact can occur when it is in the second position. Correspondingly, the proximity of the second washing support 322 to the first vibration isolation support 311 is also different, as is the proximity of the first washing support 321 to the second vibration isolation support 312. When the weight of the drum 400 increases to a certain level, the washing machine 200 can reach its maximum washing capacity. Here, by abutting the washing support to the corresponding vibration isolation support, on the one hand, the vibration reduction and isolation effect can be further improved; on the other hand, the abutment can also limit the displacement of the drum 400.

[0105] At least as Figures 5 to 8 As shown, the vibration isolation support unit is a one-piece molded structure, or the elastic support component 3 is a one-piece molded structure.

[0106] In this embodiment, the one-piece design saves space occupied by the suspension device 100. Furthermore, one-piece components are generally less prone to damage or breakage into several parts when subjected to gravity.

[0107] As for the washing machine 200, there can be multiple drums 400, with adjacent drums 400 connected to each other, and the two drums 400 at both ends are suspended inside the cabinet 300 by the suspension device 100.

[0108] Specifically, in this embodiment, such as Figures 1 to 5 As shown, the washing machine 200 has two drums 400, which are connected together by a drum connecting part 500. The outer side wall of each drum 400 is suspended in the cabinet by a suspension device 100.

[0109] In other alternative embodiments, the washing machine may have three or more drums; adjacent drums 400 are interconnected, and the two drums 400 at both ends are suspended from the housing 300 by the suspension device 100, which means that the suspension device 100 can withstand a large amount of gravity.

[0110] like Figures 1 to 7 As shown, gaps are formed between any position of the vibration isolation support unit and the outer wall surface of the drum 400 and the inner wall surface of the housing 300. That is to say, gaps are formed between both sides of the elastic support assembly and the outer wall surface of the drum 400 and the inner wall surface of the housing 300. These gaps provide a buffer space for the transmission of force from the drum 400 to the inner wall of the housing 300, which can ensure the control of the displacement of the drum 400 under extreme eccentric large displacement during the washing machine's spin-drying operation, and at the same time can greatly reduce the transmission of vibration to the housing side.

[0111] The working mode of the suspension device 100 in this utility model under dehydration and washing conditions is as follows:

[0112] Washing condition: The drum 400 is suspended symmetrically on the left and right sides. During the washing condition, due to the weight of the drum 400 itself and the weight of the water or clothes in the drum 400, the elastic support component 3 undergoes a large deformation. The first washing support part 321 can abut against the second washing support part 322 and support itself on the second washing support part 322 to improve the rigidity of the suspension device 100 to bear the weight.

[0113] Dehydration condition: The water in the drum 400 is discharged. The mass of the entire drum 400 is small and the rotation speed gradually increases, resulting in greater vibration. At this time, the elastic support component 3 gradually recovers its deformation. The first washing support part 321 gradually separates from the second washing support part 322 and is located above the second washing support part 322. The stiffness is reduced, resulting in a better dehydration and vibration isolation effect.

[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 to perform corresponding operations, thereby realizing the intelligent control of the washing machine 200 and improving the user experience.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
