Description

Technical Field

[0001] This utility model relates to the field of washing machines, and in particular to a damping support 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 time, 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 damping support device and a washing machine including the device.

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

[0008] A damping support device is provided for supporting the drum of a washing machine within the washing machine's casing. The damping support device includes:

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

[0010] The second bracket, the first end of which is used to connect to the box body;

[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 on 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 compression of the elastic support component is configured to change positively with the gravity of the cylinder, so as to switch between a first position state and a second position state.

[0014] 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 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, forming 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 compression of the elastic support assembly 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 damping support device can flexibly isolate and buffer vibrations in response to changes in the drum's weight. When the compression of the elastic support component is less than the threshold, the first washing support is in a first position separated from 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 the preset position, the deformation of the vibration isolation support unit is large, and the compression of the elastic support component is greater than the threshold, the first washing support is in a second position abutting against 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 damping support device with the change of the weight of the drum, improving the buffering and vibration reduction effect of the damping support device under different operating conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine. The damping support device achieves vibration isolation and reduction through elastic support components, reducing the number of parts and eliminating the need for traditional vibration dampers and suspension springs. This results in a more compact structure, significantly reducing the space occupied by the enclosure. It also avoids the relative movement of traditional rigidly connected structural components, preventing structural noise generated during component operation. Furthermore, the damping support device includes a washing support unit and a vibration isolation support unit, with the washing support unit mounted on top of the vibration isolation support unit, making the damping support device 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 washing support, and the second washing support has a second arcuate protrusion extending toward the first washing support.

[0019] In this design, the one-to-one correspondence between multiple first washing support parts and multiple second washing support parts can further improve the stiffness of the damping support device when it is in the second position state, and further improve the gravity that the damping support 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 damping support 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 the vibration isolation effect.

[0021] 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,

[0022] 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.

[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 damping support device is in the second position, thereby improving the stiffness of the damping support device.

[0024] 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,

[0025] The first bracket includes a first 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.

[0026] The first vibration isolation mounting part is sandwiched between the first mounting plate and the first mounting component. The first mounting plate threadedly connects the first vibration isolation mounting part to the first mounting component, and the first mounting component is used to install on the bottom of the cylinder.

[0027] In this design, the first vibration isolation mounting part further improves the vibration isolation effect of the damping support device. In addition, the first vibration isolation mounting part also increases the installation area between the damping support device and the cylinder, making the installation more stable. The mounting parts and the first mounting plate make the damping support device more firmly fixed on the cylinder.

[0028] Preferably, the second bracket includes a second mounting member, one end of which is connected to the housing. The elastic support assembly further includes a second vibration-damping mounting portion, one end of which is connected to the second end of the first vibration-damping support portion near the second mounting member, and the other end of which is connected to the second end of the second vibration-damping support portion near the second mounting member. The elastic support assembly is mounted on the second mounting member via the second vibration-damping mounting portion; or,

[0029] The second bracket includes a second mounting component and a second mounting plate. One end of the second mounting component is 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 second mounting component, 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 second mounting component.

[0030] The second vibration isolation mounting part is sandwiched between the second mounting plate and the second mounting component, and the second mounting plate threadedly connects the second vibration isolation mounting part to the second mounting component.

[0031] In this design, the second vibration isolation mounting section further improves the vibration isolation effect of the damping support device. In addition, the second vibration isolation mounting section also increases the installation area between the damping support device and the crossbeam, making the installation more stable. The second mounting plate allows the damping support device to be installed more stably on the second mounting component.

[0032] 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, the other end of the second mounting member extends downward at an angle toward the elastic support assembly, the second vibration isolation mounting part is supported on the other end of the second mounting member, and the second bracket further includes a support rib supporting between the second mounting member and the third mounting member.

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

[0034] In this design, the third mounting component increases the contact area with the housing, 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. Matching the inner surfaces of the second mounting plate and the second vibration isolation mounting part results in a large connection area and a more stable connection. Additionally, the second mounting plate and the second vibration isolation mounting part are more easily and evenly stressed.

[0035] Preferably, the first mounting plate is adapted to the inner surface of the first vibration isolation mounting part; the end face of the first 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 first mounting member connecting to the cylinder is adapted to the outer wall surface of the cylinder.

[0036] In this design, the inner surface of the first mounting plate is adapted to the inner surface of the first vibration isolation mounting part, resulting in a large connection area and a more stable connection. Furthermore, the first mounting plate and the first vibration isolation mounting part are also easier to stress on, and the stress distribution is more uniform. Setting the end face of the first mounting component to fit the outer wall surface of the cylinder also makes the installation of the damping support device and the cylinder more stable.

[0037] Preferably, the elastic support component is a one-piece molded structure.

[0038] In this solution, the aforementioned one-piece design saves space occupied by the damping support device; in addition, the one-piece component is generally not easily damaged or broken into several parts when subjected to gravity.

[0039] This utility model also provides a washing machine, which includes a cabinet, a drum, and the aforementioned damping support device.

[0040] Preferably, there are multiple cylindrical bodies, each of which is suspended from the housing by a damping support device; or,

[0041] There are multiple cylinders, and adjacent cylinders are connected to each other. The two cylinders at both ends are suspended from the box body by damping support devices.

[0042] In this design, adjacent cylinders are interconnected, and both cylinders at both ends are suspended from the box body by damping support devices, meaning that the damping support devices can withstand a large amount of gravity.

[0043] The positive and progressive effects of this utility model are as follows:

[0044] In this application, 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 of the drum's vibration. Furthermore, the first and second vibration-damping support parts are arranged 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 compression of the washing support unit 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 damping support device can flexibly isolate and buffer vibrations from changes in the weight of the drum. When the compression of the vibration isolation support unit is less than the threshold, the first washing support is in a first position separated from 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 the preset position, the deformation of the vibration isolation support unit is large, and the compression of the vibration isolation support unit is greater than the threshold, the first washing support is in a second position abutting against 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 damping support device with the change of the weight of the drum, improving the buffering and vibration reduction effect of the damping support device under different operating conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine. The damping support device achieves vibration isolation and reduction through elastic support components, reducing the number of parts and eliminating the need for traditional vibration dampers and suspension springs. This results in a more compact structure, significantly reducing the space occupied by the enclosure. It also avoids the relative movement of traditional rigidly connected structural components, preventing structural noise generated during component operation. Furthermore, the damping support device includes a washing support unit and a vibration isolation support unit, with the washing support unit mounted on top of the vibration isolation support unit, making the damping support device 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 6 As shown, this embodiment provides a damping support device 100 and a washing machine 200 including the device. The damping support device 100 is used to support the drum 400 of the washing machine 200 within the casing 300 of the washing machine 200. The damping support device 100 includes: a first bracket 1, the first end of which is connected to the bottom of 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 portion 311 and a second vibration isolation support portion 312 supported between the first bracket 1 and the second bracket 2. The first vibration isolation support 311 and the second vibration isolation support 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 321 and a second washing support 322 respectively disposed on the first vibration isolation support 311 and the second vibration isolation support 312, the first washing support 321 and the second washing support 322 are disposed opposite to each other and are both located in the receiving cavity 21; the compression amount of the elastic support assembly 3 is configured to change positively with the change of gravity of the drum 400, so as to switch between a first position state and a second position state; wherein, 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 and the second washing support 322 are abutted.

[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 helps to reduce the vibration transmitted from the drum 400 to the housing 300 and provides flexible buffering for the vibration of the drum 400. Furthermore, 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 helps to increase the support area of ​​the vibration isolation support unit on the housing 300, improve its support effect, and avoid concentrated support at a single point, which could easily damage the vibration isolation support unit.

[0077] The compression of the elastic support assembly 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 damping support device can flexibly isolate and buffer the drum 400 from gravity changes. When the compression of the elastic support assembly 3 is less than a threshold, the first washing support 321 is 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 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, the deformation of the vibration isolation support unit is large, and the compression of the elastic support component 3 is greater than the threshold. At this time, the first washing support part 321 is located at 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 have buffering and vibration reduction effects on the drum, thereby realizing the dynamic adjustment of the stiffness of the damping support device 100 with the change of the weight of the drum 400, improving the buffering and vibration reduction effect of the damping support device 100 under different working conditions of the washing machine 200, thereby optimizing the vibration isolation rate of the washing machine 200.

[0078] The damping support device 100 achieves vibration isolation and reduction 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 damping support 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 damping support device 100 more compact and space-saving. It should be noted that the gravity of the drum 400 in this embodiment includes the gravity of the drum 400 itself and the gravity of the clothes and water contained within it. The gravity of the drum 400 varies depending on the weight of the clothes and / or water inside. In other words, the gravity of the drum 400 varies depending on whether it contains clothes and / or water, and the weight of the clothes and / or water contained within.

[0079] It should be noted that when the damping support device 100 is in the first position, the washing machine 200 can be in the spin-drying state. At this time, the water in the drum 400 has been mostly drained or is in the process of draining, and the overall weight of the drum 400 is lighter. When the damping support device 100 is in the second position, the washing machine 200 can be in the washing state. 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. In addition, the material of the elastic support component 3 is rubber. Furthermore, 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 damping support device 100 is also different. The greater the degree of contact, the greater the stiffness of the damping support device 100, and vice versa.

[0080] like Figures 1 to 6 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.

[0081] 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 stiffness of the damping support device 100 when it is in the second position state, and further increase the gravity that the damping support device 100 can withstand.

[0082] 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.

[0083] 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.

[0084] 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 damping support 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.

[0085] like Figure 4As 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.

[0086] 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 damping support device 100 is in the second position state, so as to improve the stiffness of the damping support device 100.

[0087] 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.

[0088] like Figure 6 As 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 first 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 sandwiched between the first mounting plate 11 and the first mounting member 12, and the first mounting plate 11 threadedly connects the first vibration isolation mounting part 33 to the first mounting member 12, and the first mounting member 12 is used to install on the bottom of the cylinder 400.

[0089] In this embodiment, the provision of the first vibration isolation mounting part 33 further improves the vibration isolation effect of the damping support device 100. In addition, the first vibration isolation mounting part 33 also increases the mounting area between the damping support device 100 and the cylinder 400, making the installation more stable. The provision of the first mounting member 12 and the first mounting plate 11 makes the damping support device 100 more firmly fixed on the cylinder 400.

[0090] In other alternative embodiments, the first vibration isolation mounting part 33 and the second vibration isolation mounting part 34 may be omitted.

[0091] It should be noted that in embodiments without the first vibration isolation mounting part 33, the first mounting part 12 and the first mounting plate 11, the damping support device 100 can be mounted on the cylinder 400 through the first vibration isolation support part 311 and the second vibration isolation support part 312.

[0092] like Figures 2 to 5 As shown, the second bracket 2 includes a second mounting member 22, one end of which is connected to the housing 300. The elastic support assembly 3 also includes a second vibration isolation mounting part 34, one end of which is connected to the second end of the first vibration isolation support part 311 near the second mounting member 22, and the other end of which is connected to the second end of the second vibration isolation support part 312 near the second mounting member 22. The elastic support assembly 3 is mounted on the second mounting member 22 via the vibration isolation mounting part; or, the second bracket 2 includes a second mounting member 22 and a second mounting plate. 23. One end of the second mounting member 22 is 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 second mounting member 22. 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 second mounting member 22. The second vibration isolation mounting part 34 is sandwiched between the second mounting plate 23 and the second mounting member 22. The second mounting plate 23 threadedly connects the second vibration isolation mounting part 34 to the second mounting member 22.

[0093] In this embodiment, the provision of the second vibration isolation mounting part 34 further improves the vibration isolation effect of the damping support device 100. In addition, the second vibration isolation mounting part 34 also increases the mounting area of ​​the damping support device 100 and the second mounting member 22, making the installation more stable. The provision of the second mounting plate 23 makes the damping support device 100 more stably mounted on the second mounting member 22.

[0094] like Figures 1 to 5 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 mounting part 34 is supported on the other end of the second mounting member 22. The second bracket 2 also includes a support rib 25 that supports between the second mounting member 22 and the third mounting member 24.

[0095] 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.

[0096] It should be noted that in embodiments without the second mounting plate 23 and the second vibration isolation mounting portion 34, the damping support device 100 can be mounted on the second mounting member 22 via the first vibration isolation support portion 311 and the second vibration isolation support portion 312; furthermore, the cavity formed by the first vibration isolation mounting portion 33, the second vibration isolation mounting portion 34, the first vibration isolation support portion 311, and the second vibration isolation support portion 312 provides space for the first washing support portion 321 and the second washing support portion 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 component is threaded onto the first bracket and the second bracket through the mounting holes 35.

[0097] The first mounting plate 11 is adapted to the inner surface of the first vibration isolation mounting part 33. The end face of the first 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 first mounting member 12 connected to the cylinder 400 is adapted to the outer wall surface of the cylinder 400.

[0098] 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 first mounting member 12 can also make the installation of the damping support device 100 and the cylinder 400 more stable.

[0099] 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 that connects to the cylinder 400 is also arc-shaped.

[0100] Furthermore, the second mounting plate 23 is adapted to the inner surface of the second vibration isolation mounting part 34.

[0101] 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.

[0102] At least as Figure 6 As shown, the elastic support component 3 is a one-piece molded structure.

[0103] In this embodiment, the one-piece design saves space occupied by the damping support device 100. Furthermore, one-piece components are generally less prone to damage or breakage into several parts when subjected to gravity.

[0104] As for the washing machine 200, there can be multiple drums 400, and each drum 400 is suspended from the cabinet 300 by a damping support device 100.

[0105] Alternatively, multiple cylinders 400 can be provided, with adjacent cylinders 400 connected to each other, and the two cylinders 400 at both ends suspended from the box 300 by a damping support device 100.

[0106] 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. Each drum 400 is supported in the cabinet by a damping support device 100.

[0107] 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 damping support devices 100, which means that the damping support devices 100 can withstand a large amount of gravity.

[0108] The working mode of the damping support device 100 in this utility model under dehydration and washing conditions is as follows:

[0109] 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 is compressed, and the first washing support part 321 and the second washing support part 322 abut against each other to increase the rigidity of the damping support device 100 to bear the weight.

[0110] 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.

[0111] 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.
