Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a hanging device and a washing machine including the same. Background Technology

[0002] In traditional washing machines, the outer tub is connected to the casing via suspension springs and vibration dampers. The suspension springs, as elastic elements, primarily function to isolate vibrations, while the vibration dampers, as damping elements, mainly attenuate vibrations. The combination of these two components plays a crucial role in isolating vibrations from the outer tub to the casing and reducing the amplitude of the outer tub's vibration; they are the core components 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, which 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] A first bracket is used to connect the cylinder;

[0010] The second bracket is used to connect the housing;

[0011] An elastic support assembly includes a washing support part and a vibration isolation support part made of elastic material. The washing support part is connected to the first bracket, and the two ends of the vibration isolation support part are respectively connected to the first bracket and the second bracket, so that the vibration isolation support part is supported between the first bracket and the second bracket.

[0012] The pressure exerted on the washing support by the first bracket changes positively with the gravity of the drum, so that the washing support moves closer to or further away from the second bracket and can switch between a first position state and a second position state.

[0013] When in the first position, the pressure on the washing support is less than a threshold, and the washing support is separated from the second bracket and supported above the second bracket.

[0014] When in the second position, the pressure on the washing support reaches the threshold, causing the washing support to abut against the second bracket.

[0015] In this technical solution, a washing support and a vibration isolation support made of elastic material are provided. The two ends of the vibration isolation support are connected to the first bracket and the second bracket to support between the first bracket and the second bracket. Under any working condition, the vibration isolation support has a buffering and vibration reduction effect on the cylinder. By connecting the washing support to the first bracket, and ensuring that the pressure on the washing support from the first bracket changes positively with the weight of the drum, the washing support can move closer to or further away from the second bracket, switching between a first position and a second position. Specifically, when the weight of the drum is low and the center of gravity is at a preset position, the deformation of the vibration isolation support is small, and the pressure on the washing support is less than a threshold, the washing support is in a first position separated from the second bracket. At this time, the stiffness of the elastic support assembly is low, and the drum only experiences buffering and vibration reduction from the vibration isolation support. When the weight of the drum increases or the center of gravity shifts from the preset position, the deformation of the vibration isolation support is large, and the pressure on the washing support exceeds a threshold, the washing support is in a second position abutting against the second bracket. At this time, the stiffness of the elastic support assembly is high, providing better support for the drum. Both the vibration isolation support and the washing support simultaneously buffer and reduce vibrations on the drum, thus achieving dynamic adjustment of the suspension device's stiffness according to the drum's weight. This improves the buffering and vibration reduction effect of the suspension device under different operating conditions of the washing machine, thereby optimizing the washing machine's vibration isolation rate.

[0016] Preferably, there are two vibration isolation supports, which are arranged on both sides of the washing support and are arranged gradually away from each other from top to bottom in the vertical direction.

[0017] In this technical solution, two vibration isolation supports are set on both sides of the washing support. The support reliability of the vibration isolation supports is improved by increasing the number of vibration isolation supports. The two vibration isolation supports are set to gradually move away from each other from top to bottom in the vertical direction. The support reliability of the vibration isolation supports is improved by optimizing the support angle of the vibration isolation supports.

[0018] Preferably, each of the vibration isolation supports gradually moves away from the washing support from top to bottom in a vertical direction.

[0019] In this technical solution, by setting each vibration isolation support to gradually move away from the washing support from top to bottom, each vibration isolation support is at an optimal support angle, further improving the support reliability of the vibration isolation support. At the same time, it improves the uniformity of force distribution between the two vibration isolation supports, preventing one of them from being damaged due to excessive load.

[0020] Preferably, there are two vibration isolation supports, which are disposed on both sides of the washing support, and the elastic support assembly is configured to satisfy at least one of the following conditions (1)-(5):

[0021] (1) The two vibration isolation support parts are symmetrically arranged about the washing support part;

[0022] (2) The washing support gradually shrinks in the direction close to the second bracket;

[0023] (3) The number of washing support parts is multiple, and the multiple washing support parts are distributed along the line connecting the two vibration isolation support parts or along the line perpendicular to the line connecting the two vibration isolation support parts;

[0024] (4) The bottom end of the washing support protrudes toward the second bracket relative to the bottom end of the vibration isolation support;

[0025] (5) The washing support and the vibration isolation support are integrally formed.

[0026] In this technical solution, by symmetrically designing the two vibration isolation supports with respect to the washing support, the stress on the two vibration isolation supports is made more uniform, avoiding localized damage due to uneven load. By designing the washing support to gradually taper towards the second bracket, the washing support has sufficient elastic deformation space, preventing it from being crushed. By setting multiple washing supports, the support capacity of the washing support is improved. By designing the bottom of the washing support to protrude towards the second bracket relative to the bottom of the vibration isolation support, the travel distance between the non-buffered and buffered positions of the washing support is shortened, avoiding the phenomenon where the vibration isolation support deforms severely while the washing support is still functioning. By integrating the washing support with the vibration isolation support, the connection reliability between the washing support and the vibration isolation support is higher, and assembly is more convenient.

[0027] Preferably, the first support includes a first part and a second part disposed opposite to each other, and a flexible connecting part connecting the first part and the second part. The second support is disposed between the first part and the second part, and an accommodating space is formed between the first part and the second support. The washing support and the vibration isolation support are both disposed within the accommodating space. The lower surface of the first part is connected to the upper surface of the washing support and the upper surface of the vibration isolation support. The second part is used to connect the drum body.

[0028] In this technical solution, by setting a flexible connecting part, when the first part of the first support shifts due to changes in the weight of the cylinder, the flexibility of the flexible connecting part can accommodate this displacement, preventing the entire first support from causing the cylinder to fall or move upward, and also preventing the first support from being crushed. By making the first part and the second support enclose a receiving space, and placing the elastic support component within this receiving space, the elastic support component is shielded and protected, preventing damage to the elastic support component.

[0029] Preferably, there is a gap between the second support and the flexible connection.

[0030] In this technical solution, by setting a gap between the second support and the flexible connection part, that is, by preventing the second support and the flexible connection part from contacting each other, friction and collision between the second support and the flexible connection part are avoided.

[0031] Preferably, the elastic support component is connected to the corresponding first bracket or second bracket by adhesive bonding.

[0032] A washing machine includes a cabinet, a drum, and a suspension device as described above, wherein the drum is connected to the cabinet via the suspension device.

[0033] Preferably, the washing machine includes a drum connecting part and two drums, with the two ends of the drum connecting part respectively connected to the two drums. The drum connecting part and the two drums form a recess, and the suspension device is disposed in the recess. The second bracket includes a crossbeam and a bracket body connected to each other. The crossbeam is used to connect the cabinet. The bracket body is connected to the vibration isolation support part, and the shape of the bracket body matches the shape of the recess.

[0034] In this technical solution, by setting the shape of the support body of the second bracket to match the shape of the recess, the space utilization rate inside the washing machine can be improved, making the structure of the washing machine more compact.

[0035] Preferably, there is a gap between the second support and the cylinder.

[0036] In this technical solution, by setting a gap between the second support and the cylinder, friction and collision between the second support and the cylinder are avoided.

[0037] The positive and progressive effects of this utility model are as follows: by setting a washing support part and a vibration isolation support part made of elastic material, the two ends of the vibration isolation support part are connected to the first bracket and the second bracket to support between the first bracket and the second bracket. Under any working condition, the vibration isolation support part has a buffering and vibration reduction effect on the cylinder. By connecting the washing support to the first bracket, and ensuring that the pressure on the washing support from the first bracket changes positively with the weight of the drum, the washing support can move closer to or further away from the second bracket, switching between a first position and a second position. Specifically, when the weight of the drum is low and the center of gravity is at a preset position, the deformation of the vibration isolation support is small, and the pressure on the washing support is less than a threshold, the washing support is in a first position separated from the second bracket. At this time, the stiffness of the elastic support assembly is low, and the drum only experiences buffering and vibration reduction from the vibration isolation support. When the weight of the drum increases or the center of gravity shifts from the preset position, the deformation of the vibration isolation support is large, and the pressure on the washing support exceeds a threshold, the washing support is in a second position abutting against the second bracket. At this time, the stiffness of the elastic support assembly is high, providing better support for the drum. Both the vibration isolation support and the washing support simultaneously buffer and reduce vibrations on the drum, thus achieving dynamic adjustment of the suspension device's stiffness according to the drum's weight. This improves the buffering and vibration reduction effect of the suspension device under different operating conditions of the washing machine, thereby optimizing the washing machine's vibration isolation rate.

[0064] Recess 302 Detailed Implementation

[0065] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0066] like Figures 1-10 As shown, this embodiment provides a washing machine, which includes a drum 300, a cabinet 200 and a suspension device 100. The drum 300 is connected to the cabinet 200 through the suspension device 100, and the suspension device 100 has a vibration damping effect on the drum 300.

[0067] Specifically, such as Figures 1-4 As shown, the suspension device 100 includes a first bracket 1, a second bracket 2, and an elastic support assembly 3. The first bracket 1 connects to the drum body 300, and the second bracket 2 connects to the housing 200. The elastic support assembly 3 includes a washing support portion 32 and a vibration-damping support portion 31 made of elastic material. The washing support portion 32 is connected to the first bracket 1, and the two ends of the vibration-damping support portion 31 are respectively connected to the first bracket 1 and the second bracket 2, so that the vibration-damping support portion 31 is supported between the first bracket 1 and the second bracket 2. The pressure on the washing support portion 32 from the first bracket 1 changes positively correlated with the weight of the drum body 300, so that the washing support portion 32 moves closer to or further away from the second bracket 2, and can switch between a first position state and a second position state.

[0068] In the first position, the pressure on the washing support 32 is less than a threshold, and the washing support 32 is separated from the second bracket 2 and supported above the second bracket 2. In the second position, the pressure on the washing support 32 reaches the threshold, causing the washing support 32 to abut against the second bracket 2. By providing a washing support 32 and a vibration-damping support 31 made of elastic material, with both ends of the vibration-damping support 31 connected to the first bracket 1 and the second bracket 2 to support between the first bracket 1 and the second bracket 2, the vibration-damping support 31 provides buffering and vibration reduction for the drum 300 under any operating condition. By connecting the washing support 32 to the first bracket 1, and ensuring that the pressure on the washing support 32 from the first bracket 1 changes positively with the weight of the drum 300, the washing support 32 can move closer to or further away from the second bracket 2, and can switch between the first and second position states.

[0069] Specifically, when the weight of the drum 300 is small and its center of gravity is located at a preset position, the deformation of the vibration isolation support 31 is small, and the pressure on the washing support 32 is less than a threshold, the washing support 32 is located at a first position separated from the second bracket 2. At this time, the stiffness of the elastic support component 3 is low, and the drum 300 is only subjected to the buffering and vibration reduction effect of the vibration isolation support 31. When the weight of the drum 300 increases or the center of gravity shifts to the preset position, the deformation of the vibration isolation support 31 is large, and the pressure on the washing support 32 is greater than a threshold, the washing support 32 is located at a second position abutting against the second bracket 2. At this time, the stiffness of the elastic support component 3 is high, and the support effect on the drum 300 is better. The vibration isolation support 31 and the washing support 32 simultaneously have buffering and vibration reduction effects on the drum 300, thereby realizing the dynamic adjustment of the stiffness of the suspension device 100 with the change of the weight of the drum 300, improving the buffering and vibration reduction effect of the suspension device 100 under different working conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine.

[0070] In this embodiment, both the first position state and the second position state refer to a position range. Specifically, the first position state occurs when the pressure on the washing support 32 is less than a threshold, meaning the washing support 32 is separated from the second bracket 2 and supported above it. The second position state occurs when the pressure on the washing support 32 reaches the threshold, causing it to contact the second bracket 2. Figures 1-10 The washing support shown is in the first position.

[0071] In this embodiment, as Figures 5-10 As shown, there are two vibration isolation supports 31, which are arranged on both sides of the washing support 32, and the two vibration isolation supports 31 are arranged gradually away from each other from top to bottom in the vertical direction. By providing two vibration isolation supports 31 on both sides of the washing support 32, the support reliability of the vibration isolation supports 31 is improved by increasing the number of vibration isolation supports 31, and by arranging the two vibration isolation supports 31 to be arranged gradually away from each other from top to bottom in the vertical direction, the support reliability of the vibration isolation supports 31 is improved by optimizing the support angle of the vibration isolation supports 31.

[0072] Specifically, such as Figure 7 As shown, the two vibration isolation supports 31 are set away from each other from top to bottom in the vertical direction, forming a support form that is narrow at the top and wide at the bottom, making the support more stable.

[0073] Of course, in other embodiments, only one vibration isolation support 31 can be provided, which can also play a supporting and vibration reduction role. Or in more embodiments, multiple vibration isolation support 31 can be provided to improve support stability, which will not be elaborated here.

[0074] In this embodiment, each vibration isolation support 31 gradually moves away from the washing support 32 from top to bottom in a vertical direction. That is, as... Figure 7 As shown, the two vibration isolation supports 31 form an "eight" shape. By setting each vibration isolation support 31 to gradually move away from the washing support 32 from top to bottom, each vibration isolation support 31 is at an optimal support angle, further improving the support reliability of the vibration isolation support 31. At the same time, it improves the uniformity of force distribution between the two vibration isolation supports 31, preventing one of the vibration isolation supports 31 from being damaged due to excessive load.

[0075] Furthermore, the two vibration isolation supports 31 are symmetrically arranged about the washing support 32. By making the two vibration isolation supports 31 symmetrical about the washing support 32, the force on the two vibration isolation supports 31 is more even, avoiding local damage caused by uneven load.

[0076] Of course, in other embodiments, the vibration isolation support 31 may also maintain the same distance from the washing support 32 from top to bottom, or partially maintain the same distance from the washing support 32 from top to bottom, with the remaining part gradually moving away from the washing support 32 from top to bottom, which will not be described in detail here.

[0077] In this embodiment, as Figure 7 , Figure 9 and Figure 10 As shown, the washing support portion 32 gradually tapers towards the second bracket 2. That is, in this embodiment, the bottom end of the washing support portion 32 is narrower than the top end. By setting the washing support portion 32 to gradually taper towards the second bracket 2, the washing support portion 32 has sufficient elastic deformation space to prevent the washing support portion 32 from being squeezed and damaged.

[0078] Meanwhile, the bottom end of the washing support protrudes towards the second bracket 2 relative to the bottom end of the vibration isolation support 31. By providing multiple washing support parts 32, the supporting capacity of the washing support part 32 is improved. By setting the washing support part 32 so that its bottom end protrudes towards the second bracket 2 relative to the bottom end of the vibration isolation support 31, the travel distance between the position where the washing support part 32 does not provide cushioning and the position where it does provide cushioning is shortened, thus avoiding the phenomenon that the vibration isolation support 31 is severely deformed while the washing support part 32 has not yet played its role.

[0079] Of course, in other embodiments, the bottom end of the washing support 32 is flush with the bottom end of the vibration isolation support 31, which can also have better support capabilities, and will not be described in detail here.

[0080] In this embodiment, as Figure 5 , Figures 8-10As shown, there is one washing support 32, and the washing support 32 extends a certain length along the line connecting the two vibration isolation supports 31 perpendicular to the line connecting the two vibration isolation supports 31.

[0081] Of course, in other embodiments, multiple washing support portions 32 can also be provided to improve the support effect of the washing support portions 32. Specifically, when there are multiple washing support portions 32, they can be distributed along the line connecting the two vibration isolation support portions 31 or along the line perpendicular to the line connecting the two vibration isolation support portions 31.

[0082] In this embodiment, the washing support 32 and the vibration isolation support 31 are integrally formed. By integrally forming the washing support 32 and the vibration isolation support 31, the connection reliability of the washing support 32 and the vibration isolation support 31 is higher, and the assembly is more convenient.

[0083] Of course, in other embodiments, the washing support 32 and the vibration isolation support 31 can also be set separately, which will not be described in detail here.

[0084] In this embodiment, as Figures 8-10 As shown, the first support 1 includes a first part 11 and a second part 12 disposed opposite to each other, and a flexible connecting part 13 connecting the first part 11 and the second part 12. The second support 2 is disposed between the first part 11 and the second part 12, forming a receiving space 201. A washing support part 32 and a vibration-damping support part 31 are both disposed within the receiving space 201. The lower surface of the first part 11 is connected to the upper surface of both the washing support part 32 and the vibration-damping support part 31. The second part 12 is used to connect to the drum body 300. By providing the flexible connecting part 13, when the first part of the first support 1 shifts due to changes in the gravity of the drum body 300, the flexibility of the flexible connecting part 13 can accommodate this displacement, preventing the entire first support 1 from causing the drum body 300 to fall or rise, and also preventing the first support 1 from being crushed. By having the first part 11 and the second support 2 form the receiving space 201, and placing the elastic support assembly 3 within this receiving space, the elastic support assembly 3 is shielded and protected, preventing damage to the elastic support assembly.

[0085] Specifically, both the washing support 32 and the vibration isolation support 31 are connected to their respective brackets by adhesive bonding. The washing support 32 is connected to the first bracket 1 by adhesive bonding, and the vibration isolation support 31 is connected to the first bracket 1 and the second bracket 2 by adhesive bonding. The first bracket 1 is then connected to the cylinder 300 by bolts. Specifically, the washing support 32 has a wide contact surface with the lower surface of the first part 11, resulting in a large bonding area. During the vulcanization process, the washing support 32 is fixed to the first part 11, ensuring a reliable connection. Furthermore, the vibration isolation support 31 also has a wide contact surface with the first part 11 of the first bracket 1 and with the second bracket 2, resulting in a large bonding area. These connections are also fixed using a vulcanization process, ensuring high reliability.

[0086] Among them, such as Figures 1-4 As shown, there is a gap between the second support 2 and the flexible connecting part 13. Simultaneously, there is a gap between the second support 2 and the cylinder 300. By providing gaps between the second support 2 and the flexible connecting part 13, and between the second support 2 and the cylinder 300, that is, the second support 2 and the flexible connecting part 13 do not contact each other, and the second support 2 and the cylinder 300 support do not contact each other, thus avoiding friction and collision between the second support 2 and the flexible connecting part 13, and between the second support 2 and the cylinder 300.

[0087] Of course, in other embodiments, the washing support 32 and the vibration isolation support 31 can be connected to the corresponding bracket using other connection methods of the prior art, or the bonding process can be done by using adhesive instead of vulcanization, etc., which will not be elaborated here.

[0088] In this embodiment, as Figures 1-7 As shown, the washing machine includes a drum connecting part 301 and two drums 300. The two ends of the drum connecting part 301 are respectively connected to the two drums 300. The drum connecting part 301 and the two drums 300 form a recess 302. A hanging device 100 is disposed within the recess 302. There is one hanging device 100, and the connection point between the hanging device 100 and the drum connecting part 301 is located in the middle of the two drums 300, constituting a single-point central suspension. Specifically, as... Figure 5 As shown, the lower surface of the second part 12 of the first bracket 1 is in close contact with the upper surface of the cylinder connection part. The contact area between the two is large, and two or more bolts can be used to connect the second part 12 to the cylinder connection part 301, thereby achieving a reliable connection between the first bracket 1 and the cylinder 300.

[0089] At the same time, there is also a gap between the second support 2 and the second part 12 of the first support 1 to avoid friction and collision between the second support 2 and the second part 12 of the first support 1.

[0090] In this embodiment, the second support 2 includes a crossbeam 22 and a support body 21 connected together. The crossbeam 22 is used to connect the housing 200, and the support body 21 is connected to the vibration isolation support 31. The shape of the support body 21 matches the shape of the recess 302. By setting the shape of the support body 21 of the second support 2 to match the shape of the recess 302, the drum 300 is suspended on the housing 200 by a single-point central suspension method, which can improve the space utilization inside the washing machine and make the structure of the washing machine more compact.

[0091] Of course, in other embodiments, two or more hanging devices 100 can be provided in the washing machine. The hanging method is not limited to central hanging. It can also be two-sided hanging, that is, two hanging devices 100 are symmetrically arranged on both sides of the drum 300 to connect the drum 300 and the cabinet 200. Alternatively, a combination of central hanging and two-sided hanging can be used to connect the drum 300 and the cabinet 200. These will not be elaborated further here.

[0092] The washing machine 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 intelligent control of the washing machine 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.
