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. 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 from the casing of the washing machine, the suspension device comprising:

[0009] The first support, the first end of the first support is used to connect the cylinder;

[0010] The second bracket has its first end connected to the housing.

[0011] An elastic support assembly is provided, with its first end connected to the second end of the first bracket and its second end connected to the second end of the 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 includes a first vibration isolation support part and a second vibration isolation support part supported between the first bracket and the second bracket. The first vibration isolation support part and the second vibration isolation support part are arranged opposite to each other and form a receiving cavity with the first bracket and the second bracket.

[0012] The washing support unit includes a first washing support and a second washing support respectively disposed in the first vibration isolation support and the second vibration isolation support. The first washing support and the second washing support are disposed opposite to each other and are both located in the receiving cavity.

[0013] The washing support unit is configured to switch between a first position state and a second position state as the weight of the drum changes.

[0014] When in the first position, the first washing support and the second washing support are separated.

[0015] When in the second position, the first washing support and the second washing support are in contact.

[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. Furthermore, the first and second vibration-damping support parts are positioned opposite each other and form a receiving cavity with the first and second supports. This arrangement increases the support area of ​​the vibration-damping support unit on the housing, improving its support effect and avoiding concentrated support at a single point, which could easily damage the vibration-damping support unit. The washing support unit is configured to change with the weight of the drum. The tension on the washing support unit from the first support changes positively with the weight of the drum, causing the first washing support part to move closer to or further away from the second washing support part, switching between a first position and a second position. In other words, the suspension device can flexibly isolate and buffer the drum's vibrations in response to changes in its weight. The tension on the vibration-damping support unit is less than a threshold value. When the first washing support is in a first position separated from the second washing support, the elastic support component has low stiffness, 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 vibration isolation support unit is large, and the tension on the vibration isolation support unit exceeds a threshold. In this second position, the first washing support is in a second position abutting against the second washing support. At this time, the elastic support component has high stiffness and provides better support for the drum. The vibration isolation support unit and the washing support unit simultaneously provide buffering and vibration reduction for the drum, thereby realizing the dynamic adjustment of the stiffness of the suspension device with the weight change of the drum, improving the buffering and vibration reduction effect of the suspension device under different operating conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine. In addition, the suspension device includes a washing support unit and a vibration isolation support unit, and the washing support unit is set on the vibration isolation support unit, making the suspension device more compact and saving its space.

[0017] Preferably, there are multiple first washing support portions and multiple second washing support portions, with each of the multiple first washing support portions and multiple second washing support portions corresponding one-to-one; and / or, the first washing support portion has a first arcuate protrusion extending toward the second washing support portion, and the second washing support portion has a second arcuate protrusion extending toward the first washing support portion.

[0018] 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.

[0019] 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 state to the second position state; in addition, the first and second arc-shaped protrusions can also increase the buffer distance between the first and second washing support parts, improving the vibration isolation effect.

[0020] Preferably, the width of the first arc-shaped protrusion along the axial direction of the receiving cavity is not less than the width of the first washing support portion along the axial direction of the receiving cavity; and / or,

[0021] The width of the second arc-shaped protrusion along the axial direction of the receiving cavity is not less than the width of the second washing support along the axial direction of the receiving cavity.

[0022] 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.

[0023] Preferably, the elastic support assembly further includes a first vibration isolation mounting portion, one end of the second vibration isolation mounting portion is connected to the first end of the first vibration isolation support portion near the first bracket, and the other end of the first vibration isolation mounting portion is connected to the first end of the second vibration isolation support portion near the first bracket. The elastic support assembly is mounted on the cylinder through the first vibration isolation mounting portion; or,

[0024] The first bracket includes a mounting component and a first mounting plate. The elastic support assembly also includes a first vibration isolation mounting part. One end of the first vibration isolation mounting part is connected to the first end of the first vibration isolation support part near the first bracket, and the other end of the first vibration isolation mounting part is connected to the first end of the second vibration isolation support part near the first bracket.

[0025] The first vibration isolation mounting part is located between the first mounting plate and the mounting component, and the first mounting plate threadedly connects the first vibration isolation mounting part to the mounting component.

[0026] In this design, the first vibration isolation mounting part further improves the vibration isolation effect of the suspension device. In addition, the first vibration isolation mounting part also increases the installation area between the suspension device and the cylinder, making the installation more stable. The mounting parts and the first mounting plate make the suspension device more firmly fixed to the cylinder.

[0027] Preferably, the second support includes a crossbeam with both ends for connection to the housing. The elastic support assembly further includes a second vibration isolation mounting portion, one end of which is connected to the second end of the first vibration isolation support portion near the crossbeam, and the other end of which is connected to the second end of the second vibration isolation support portion near the crossbeam. The elastic support assembly is mounted on the crossbeam via the vibration isolation mounting portion; or,

[0028] The second support includes a crossbeam and a second mounting plate. The two ends of the crossbeam are used to connect to the housing. The elastic support assembly also includes a second vibration isolation mounting part. One end of the second vibration isolation mounting part is connected to the second end of the first vibration isolation support part near the crossbeam, and the other end of the second vibration isolation mounting part is connected to the second end of the second vibration isolation support part near the crossbeam.

[0029] The second vibration isolation mounting part is located between the second mounting plate and the crossbeam, and the second mounting plate threadedly connects the second vibration isolation mounting part to the crossbeam.

[0030] In this design, the second vibration isolation mounting section further improves the vibration isolation effect of the suspension device. In addition, the second vibration isolation mounting section also increases the installation area between the suspension device and the crossbeam, making the installation more stable. The second mounting plate makes the suspension device more stably suspended on the crossbeam.

[0031] Preferably, the first mounting plate is adapted to the inner surface of the first vibration isolation mounting part; the end face of the mounting member connecting to the first vibration isolation mounting part is adapted to the outer surface of the first vibration isolation mounting part; and the end face of the mounting member connecting to the cylinder is adapted to the outer wall surface of the cylinder.

[0032] In this design, the inner surfaces of the first mounting plate and the first vibration isolation mounting part are adapted to each other, resulting in a large connection area and a more stable connection. In addition, the first mounting plate and the first vibration isolation mounting part are also easier to bear force and the force is more uniform. The limitation of the two end faces of the mounting part can also make the installation of the suspension device and the cylinder more stable.

[0033] Preferably, the second mounting plate is adapted to the inner surface of the second vibration isolation mounting part.

[0034] In this solution, the above-mentioned arrangement results in a large connection area between the second mounting plate and the second vibration isolation mounting part, making the connection more stable. In addition, the second mounting plate and the second vibration isolation mounting part are also easier to bear force, and the force is more even.

[0035] Preferably, the elastic support component is a one-piece molded structure.

[0036] 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.

[0037] This utility model also provides a washing machine, which includes a cabinet, a drum, and the aforementioned suspension device.

[0038] Preferably, there are multiple cylindrical bodies, each of which is suspended from the housing by a suspension device; or,

[0039] 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.

[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 assembly 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 to the housing and for providing flexible buffering of the drum's vibration. Furthermore, the first and second vibration isolation support parts are arranged opposite to each other and form a receiving cavity with the first and second supports. This arrangement increases the support area of ​​the vibration isolation support unit on the housing, improves its support effect, and avoids concentrated support at a single point, which can easily damage the vibration isolation support unit. The washing support unit is configured to change with the weight of the drum. The tension on the washing support unit from the first support changes positively with the weight of the drum, thereby moving the first washing support part 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 vibrations due to changes in its weight. The tension on the vibration isolation support unit... When the load is below a threshold, the first washing support is in a first position separated from the second washing support. At this time, the elastic support component has low stiffness, 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 vibration isolation support unit is large. When the tension on the vibration isolation support unit exceeds the threshold, the first washing support is in a second position abutting against the second washing support. At this time, the elastic support component has high stiffness and provides better support for the drum. The vibration isolation support unit and the washing support unit simultaneously provide buffering and vibration reduction for 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 operating conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine. In addition, the suspension device includes a washing support unit and a vibration isolation support unit, and the washing support unit is set on the vibration isolation support unit, making the suspension device more compact and saving its space.

[0066] 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.

[0067] 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, the first end of which is connected to the drum 400; a second bracket 2, the first end of which is connected to 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 which is connected to the second end of the second bracket 2. The elastic support assembly 3 includes a vibration isolation support unit and a washing support unit made of elastic material. The vibration isolation support unit includes a first vibration isolation support part 311 and a second vibration isolation support part 312 supported between the first bracket 1 and the second bracket 2. The support portion 311 and the second vibration isolation support portion 312 are disposed opposite to each other and form a receiving cavity 21 with the first bracket 1 and 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 isolation support portion 311 and the second vibration isolation support portion 312, the first washing support portion 321 and the second washing support portion 322 are disposed opposite to each other and are both located in the receiving cavity 21; the washing support unit is configured to switch between a first position state and a second position state as the gravity of the drum 400 changes; wherein, in the first position state, the first washing support portion 321 and the second washing support portion 322 are separated; in the second position state, the first washing support portion 321 and the second washing support portion 322 are abutted together.

[0068] 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. In addition, the first vibration isolation support part 311 and the second vibration isolation support part 312 are arranged opposite to each other and form a receiving cavity 21 with the first bracket 1 and the second bracket 2. This arrangement is beneficial for increasing the support area of ​​the vibration isolation support unit on the housing 300, improving its support effect, and avoiding concentrated support at one point, which can easily damage the vibration isolation support unit.

[0069] The washing support unit is configured to change with the weight of the drum 400. The tension on the washing support unit from the first bracket 1 changes positively with the weight of the drum 400, thereby causing the first washing support 321 to move closer to or further away from the second washing support 322, switching between a first position state and a second position state. In other words, the suspension device can flexibly isolate and buffer the vibration of the drum 400 in response to changes in its weight. When the tension on the washing support unit is less than a threshold, the first washing support 321 is located in a first position separated from the second washing support 322. At this time, the stiffness of the elastic support assembly 3 is low, and the drum 400 is only subjected to vibration isolation support. The support unit provides buffering and vibration reduction. When the weight of the drum increases or the center of gravity shifts to a preset position, the deformation of the vibration isolation support unit is large, and the tension on the washing support unit exceeds a threshold. At this time, the first washing support part 321 is located in the second position that abuts against the second washing support part 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 provide buffering and vibration reduction for 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 under different working conditions of the washing machine 200, and thus optimizing the vibration isolation rate of the washing machine 200.

[0070] It should be noted that when the suspension device 100 is in the first position, the washing machine 200 can be in spin-drying mode, at which point the water in the drum 400 is basically drained, and the overall weight of the drum 400 becomes lighter. When the suspension device 100 is in the second position, the washing machine 200 can be in washing mode, at which point the water in the drum 400 has not yet been drained, and the overall weight of the drum 400 is very heavy. Furthermore, the elastic support component 3 is made of rubber. Additionally, the stiffness of the suspension device 100 varies depending on the degree of contact between the first washing support part 321 and the second washing support part 322, i.e., the degree of compression. A greater degree of contact results in greater stiffness of the suspension device 100, and vice versa.

[0071] There are multiple first washing support portions 321 and multiple second washing support portions 322, with each of the multiple first washing support portions 321 and multiple second washing support portions 322 corresponding to one another; and / or, the first washing support portion 321 has a first arcuate protrusion extending toward the second washing support portion 322, and the second washing support portion 322 has a second arcuate protrusion extending toward the first washing support portion 321.

[0072] In this embodiment, there is one first washing support 321 and one corresponding second washing support 322, with one first washing support 321 and one second washing support 322 in a one-to-one correspondence.

[0073] In other embodiments, there are multiple first washing support portions 321 and multiple second washing support portions 322. The multiple first washing support portions 321 and multiple second washing support portions 322 are arranged in a one-to-one correspondence, which can further improve the rigidity of the suspension device 100 when the suspension device 100 is in the second position state, and further improve the gravity that the suspension device 100 can withstand.

[0074] Furthermore, the arrangement of the first arc-shaped protrusion and the second arc-shaped protrusion can shorten the distance between the first washing support 321 and the second washing support 322, thereby improving the efficiency of the suspension device 100 in switching from the first position state to the second position state. In addition, the first arc-shaped protrusion and the second arc-shaped protrusion can also increase the buffer distance between the first washing support 321 and the second washing support 322, thereby improving the vibration isolation effect.

[0075] It should be noted that a plurality of first washing support portions 321 are sequentially arranged on the first vibration isolation support portion 311 along the direction from the first end of the elastic support component 3 toward the second end of the elastic support component 3; and a plurality of second washing support portions 322 are sequentially arranged on the second vibration isolation support portion 312 along the direction from the first end of the elastic support component 3 toward the second end of the elastic support component 3.

[0076] like Figure 4 As shown, the width of the first arc-shaped protrusion along the axial direction of the receiving cavity 21 is not less than the width of the first washing support 321 along the axial direction of the receiving cavity 21; and / or, the width of the second arc-shaped protrusion along the axial direction of the receiving cavity 21 is not less than the width of the second washing support 322 along the axial direction of the receiving cavity 21.

[0077] 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.

[0078] It should be noted that, in its natural state, the first and second arc-shaped protrusions are as close as possible to each other, even with a gap between them.

[0079] like Figure 4As shown, the elastic support assembly 3 further includes a first vibration isolation mounting part 33, one end of the second vibration isolation mounting part 34 is connected to the first end of the first vibration isolation support part 311 near the first bracket 1, and the other end of the first vibration isolation mounting part 33 is connected to the first end of the second vibration isolation support part 312 near the first bracket 1. The elastic support assembly 3 is mounted on the cylinder 400 through the first vibration isolation mounting part 33; or, the first bracket 1 includes a mounting member 12 and a first mounting plate 11, and the elastic support assembly 3 further includes a first vibration isolation mounting part 33, one end of the first vibration isolation mounting part 33 is connected to the first end of the first vibration isolation support part 311 near the first bracket 1, and the other end of the first vibration isolation mounting part 33 is connected to the first end of the second vibration isolation support part 312 near the first bracket 1; wherein, the first vibration isolation mounting part 33 is located between the first mounting plate 11 and the mounting member 12, and the first mounting plate 11 threadedly connects the first vibration isolation mounting part 33 to the mounting member 12.

[0080] In this embodiment, the provision of the first vibration isolation mounting part 33 further improves the vibration isolation effect of the suspension device 100. In addition, the first vibration isolation mounting part 33 also increases the installation area of ​​the suspension device 100 and the cylinder 400, making the installation more stable. The provision of the mounting part 12 and the first mounting plate 11 makes the suspension device 100 more stably fixed on the cylinder 400.

[0081] In other embodiments, the first vibration isolation section and the second vibration isolation section may be omitted.

[0082] It should be noted that in embodiments without the first vibration isolation mounting part 33, mounting part 12 and first mounting plate 11, the suspension device 100 can be mounted on the cylinder 400 via the first vibration isolation support part 311 and the second vibration isolation support part 312.

[0083] like Figure 1-3 As shown, the second support 2 includes a crossbeam 22, with both ends of the crossbeam 22 connected to the housing 300. The elastic support assembly 3 also includes a second vibration isolation mounting part 34. One end of the second vibration isolation mounting part 34 is connected to the second end of the first vibration isolation support part 311 near the crossbeam 22, and the other end of the second vibration isolation mounting part 34 is connected to the second end of the second vibration isolation support part 312 near the crossbeam 22. The elastic support assembly 3 is mounted on the crossbeam 22 through the vibration isolation mounting part; or, the second support 2 includes a crossbeam 22 and a second mounting plate 2. 3. The two ends of the crossbeam 22 are used to connect to the housing 300. The elastic support assembly 3 also includes a second vibration isolation mounting part 34. One end of the second vibration isolation mounting part 34 is connected to the second end of the first vibration isolation support part 311 near the crossbeam 22, and the other end of the second vibration isolation mounting part 34 is connected to the second end of the second vibration isolation support part 312 near the crossbeam 22. The second vibration isolation mounting part 34 is located between the second mounting plate 23 and the crossbeam 22. The second mounting plate 23 threadedly connects the second vibration isolation mounting part 34 to the crossbeam 22.

[0084] In this embodiment, the provision of the second vibration isolation mounting part 34 further improves the vibration isolation effect of the suspension device 100. In addition, the second vibration isolation mounting part 34 also increases the mounting area of ​​the suspension device 100 and the crossbeam 22, making the installation more stable. The provision of the second mounting plate 23 makes the suspension device 100 more stably suspended on the crossbeam 22.

[0085] It should be noted that in embodiments without the second mounting plate 23 and the second vibration isolation mounting part 34, the suspension device 100 can be mounted on the crossbeam 22 via the first vibration isolation support part 311 and the second vibration isolation support part 312; furthermore, the cavity formed by the first vibration isolation mounting part 33, the second vibration isolation mounting part 34, the first vibration isolation support part 311, and the second vibration isolation support part 312 provides space for the first washing support part 321 and the second washing support part 322 to abut against each other; as Figure 4 As shown, the first vibration isolation mounting part and the second vibration isolation mounting part are each provided with corresponding mounting holes 35, and the elastic support assembly is threaded onto the first bracket and the second bracket through the mounting holes 35.

[0086] Mounting hole 35 Figure 1-3 As shown, the first mounting plate 11 is adapted to the inner surface of the first vibration isolation mounting part 33; the end face of the mounting member 12 connected to the first vibration isolation mounting part 33 is adapted to the outer surface of the first vibration isolation mounting part 33, and the end face of the mounting member 12 connected to the cylinder 400 is adapted to the outer wall surface of the cylinder 400.

[0087] In this embodiment, the inner surface of the first mounting plate 11 is adapted to the inner surface of the first vibration isolation mounting part 33, so that the connection area between the first mounting plate 11 and the first vibration isolation mounting part 33 is large and the connection is relatively stable. In addition, the first mounting plate 11 and the first vibration isolation mounting part 33 are also easier to bear force and the force is relatively uniform. The limitation of the two end faces of the mounting member 12 can also make the installation of the suspension device 100 and the cylinder 400 more stable.

[0088] It should be noted that the outer wall of the cylinder 400 is arc-shaped, and the end face of the mounting part 12 that connects to the cylinder 400 is also arc-shaped.

[0089] like Figure 1-3 As shown, the second mounting plate 23 is adapted to the inner surface of the second vibration isolation mounting part 34.

[0090] In this embodiment, the above-mentioned arrangement results in a large connection area between the second mounting plate 23 and the second vibration isolation mounting part 34, making the connection more stable. In addition, the second mounting plate 23 and the second vibration isolation mounting part 34 are also easier to bear force, and the force is more uniform.

[0091] like Figure 4 As shown, the elastic support component 3 is a one-piece molded structure.

[0092] 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.

[0093] This utility model also provides a washing machine 200, which includes a cabinet 300, a drum 400 and the aforementioned hanging device 100.

[0094] like Figure 1-2 As shown, there are multiple cylinders 400, each of which is suspended from the box 300 by a suspension device 100; or,

[0095] 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.

[0096] In this embodiment, the washing machine 200 has two drums connected together, and each drum is suspended from the cabinet by a suspension device.

[0097] In other embodiments, the washing machine 200 may have three or more drums; 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, which means that the suspension device 100 can withstand a large amount of gravity.

[0098] The advantages of this utility model are summarized as follows:

[0099] 1. This utility model takes into account the different stiffness, damping and limiting capabilities required for washing and dehydration under different working conditions by deforming rubber or other elastic damping components, and achieves the ideal control state under the above-mentioned different working conditions, with better load-bearing, vibration isolation and limiting capabilities of the lifting force suspension system.

[0100] 2. 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. This eliminates the traditional method of suspending the housing 300 with dampers and suspension springs, reducing the space occupied by the suspension system in the housing 300.

[0101] 3. Reduce the number of connecting parts to avoid relative movement of traditional hard-connected structural components and eliminate such vibration and noise sources.

[0102] The working mode of the suspension device 100 in this utility model under dehydration and washing conditions is as follows:

[0103] 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 in the drum 400, the elastic support component 3 is stretched. The first washing support part 321 and the second washing support part 322 abut against each other to increase the rigidity of the suspension device 100 to bear the weight. The elastic support component 3 subjected to the weight acts on the crossbeam 22.

[0104] Dehydration condition: Water in the drum 400 is discharged. The mass of the entire drum 400 is relatively small, but the rotation speed gradually increases, resulting in greater vibration. At this time, the elastic support component 3 recovers its deformation, the first washing support part 321 and the second washing support part 322 separate, the stiffness decreases, and a better dehydration vibration isolation effect is produced.

[0105] 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.
