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 shock absorbers are located at the top and bottom of the outer barrel, respectively, and are connected to the housing. This layout makes the overall structure not compact enough, occupies a large amount of internal space, 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 shortcomings of existing suspension devices, which have many components and cannot meet the different stiffness and damping requirements under washing and dehydration conditions, and to provide a suspension 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 suspension device for suspending the drum of a washing machine from the casing of the washing machine, the suspension device comprising: a first bracket, the first end of the first bracket being used to connect to the drum;

[0009] A second bracket is used to connect the housing, and the second bracket forms a receiving cavity, with the second end of the first bracket extending into the receiving cavity;

[0010] An elastic support assembly is disposed in the receiving cavity. The elastic support assembly includes a vibration isolation support unit and a washing support unit made of elastic material. The vibration isolation support unit is supported between the second end of the first bracket and the inner wall surface of the receiving cavity, and the washing support unit is disposed at the second end of the first bracket.

[0011] The second end of the first support is configured to move closer to or further away from the second support as the weight of the cylinder changes, and can switch between a first position state and a second position state;

[0012] When in the first position, the washing support unit is separated from the inner wall of the receiving cavity;

[0013] When in the second position, the washing support unit abuts against the inner wall of the receiving cavity.

[0014] In this technical solution, a washing support unit and a vibration isolation support unit made of elastic material are set up. The two ends of the vibration isolation support unit are connected to the inner wall of the first support and the receiving cavity to support between the inner wall of the first support and the receiving cavity. Under any working condition, the vibration isolation support unit has a buffering and vibration reduction effect on the cylinder. By connecting the washing support unit to the first bracket, the washing support unit can move closer to or further away from the inner wall of the receiving cavity, and can switch between a first position and a second position. When the weight of the drum is small and the center of gravity is located at a preset position, the deformation of the vibration isolation support unit is small, and the washing support unit is located in the first position separated from the inner wall of the receiving cavity. 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 washing support unit is located in the second position abutting against the inner wall of the receiving cavity. At this time, the stiffness of the elastic support component is high, and the support effect on the drum is better. The vibration isolation support unit and the washing support unit simultaneously have the buffering and vibration reduction effect on the drum, thereby realizing the dynamic adjustment of the stiffness of the suspension device with the change of the weight of the drum, improving the buffering and vibration reduction effect of the suspension device under different operating conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine.

[0015] Preferably, the vibration isolation support unit includes a first support portion and a second support portion that are connected to each other;

[0016] The first support portion is sleeved on the outside of the second end of the first bracket, and the second support portion is in contact with the inner wall of the receiving cavity.

[0017] In this technical solution, the first support portion is sleeved on the outside of the second end of the first bracket to increase the connection area, so that the first bracket is more stably installed on the first support portion; in addition, the second support portion fits against the inner wall surface of the receiving cavity. This arrangement makes the second support portion match the inner wall surface of the receiving cavity, with a large contact area, so that the inner wall surface of the receiving cavity can better bear the force. That is to say, the interaction area between the second support portion and the receiving cavity is large, the force on the receiving cavity is more uniform, and the pressure it receives is relatively small, while the gravity it bears is relatively large.

[0018] Preferably, the washing support unit is connected to the side of the first support portion facing the inner wall of the receiving cavity, and protrudes relative to the first support portion facing the inner wall of the receiving cavity.

[0019] In this technical solution, by connecting the washing support unit to the side of the first support portion facing the inner wall of the receiving cavity and protruding relative to the inner wall of the first support portion facing the receiving cavity, the travel distance between the position where the washing support unit does not provide a buffering effect and the position where it provides a buffering effect is shortened, thus avoiding the phenomenon that the vibration isolation support unit is severely deformed while the washing support unit has not yet played its role.

[0020] Preferably, there are two second support portions, and the two second support portions are symmetrically arranged about the first support portion;

[0021] An installation space is formed between the first support portion and the two second support portions, and the washing support unit is disposed within the installation space.

[0022] In this technical solution, by setting two second support parts on both sides of the washing support unit, the support reliability of the vibration isolation support unit is improved by increasing the number of second support parts. By setting the washing support unit in the installation space, the structure of the suspension device can be made more compact and the overall size of the suspension device can be reduced.

[0023] Preferably, the suspension device further includes a limiting member disposed on the inner wall of the receiving cavity and located on the movement path of the washing support unit when switching between the first position state and the second position state. The limiting member is used to cooperate with the washing support unit so that the washing support unit moves within a preset range.

[0024] In this technical solution, by setting a limiting component, the limiting component is located on the movement path of the washing support unit when switching between the first position state and the second position state. The limiting component is used to cooperate with the washing support unit. The limiting component can shorten the travel of the washing support unit from the position that does not provide a buffering effect to the position that provides a buffering effect, so as to avoid the phenomenon that the vibration isolation support unit is severely deformed while the washing support unit has not yet played its role. At the same time, the limiting component allows the washing support unit to move within a preset range, which can reduce the shaking amplitude of the drum.

[0025] Preferably, in the second position state, the washing support unit abuts against the limiting member.

[0026] In this technical solution, in the second position state, the washing support unit abuts against the limiting member, thereby relying on the limiting member to provide support force.

[0027] Preferably, the vibration isolation support unit includes a first support portion and a second support portion that are connected to each other;

[0028] The first support portion is sleeved on the outside of the second end of the first bracket, and the second support portion is in contact with the inner wall of the receiving cavity.

[0029] The washing support unit is connected to the side of the first support portion facing the inner wall of the receiving cavity and protrudes relative to the first support portion facing the inner wall of the receiving cavity. The limiting member has a limiting groove, and in the second position state, the washing support unit is embedded in the limiting groove.

[0030] In this technical solution, a limiting groove is provided on the limiting component to cooperate with the washing support unit. In the second position state, the washing support unit is embedded in the limiting groove. After the washing support unit abuts against the limiting component, better limiting effect can be achieved, which can further reduce the shaking amplitude of the drum.

[0031] Preferably, the vibration isolation support unit includes a first support portion and a second support portion that are connected to each other;

[0032] The first support portion is sleeved on the outside of the second end of the first bracket, and the second support portion is in contact with the inner wall of the receiving cavity.

[0033] The number of the second support parts is two, and the two second support parts are symmetrically arranged about the first support part;

[0034] An installation space is formed between the first support portion and the two second support portions, and the washing support unit is disposed within the installation space;

[0035] Two grooves are formed between the washing support unit and the two second support parts. The limiting member has two protrusions. When in the second position, the two protrusions respectively engage with the two grooves.

[0036] In this technical solution, by setting two second support parts, the support effect of the elastic support component can be improved. Two grooves are formed on the elastic support component, and protrusions that cooperate with the two grooves are set on the limiting part, which can further improve the limiting effect of the limiting part.

[0037] Preferably, the second support includes a crossbeam and an annular support, the two ends of the crossbeam being connected to the housing, and the annular support being an annular structure with an opening, the end of the annular support having the opening being connected to the crossbeam facing the side of the cylinder; wherein, the annular support and the crossbeam form the receiving cavity;

[0038] Alternatively, the second support includes a crossbeam and an annular support. The two ends of the crossbeam are used to connect to the housing. The annular support is an annular structure with an opening. One end of the annular support with the opening is connected to the crossbeam and faces the side of the cylinder. The annular support and the crossbeam form the receiving cavity. The vibration isolation support unit is attached to the inner wall of the annular support along the circumferential direction of the annular support.

[0039] In this technical solution, the two ends of the crossbeam are used to connect to the box body, so that the crossbeam can be stably connected to the box body; in addition, the open annular structure has two connection ends to the crossbeam, which makes the annular bracket more stably connected to the crossbeam; furthermore, the vibration isolation support unit is attached to the inner wall surface of the annular bracket along the circumferential direction of the annular bracket, so that the vibration isolation support unit can cover the entire inner wall surface of the annular bracket, and since it is an annular structure, the circumference of the inner wall surface of the annular bracket is relatively long. That is to say, the above-mentioned arrangement further increases the effective area of ​​the vibration isolation support unit and the annular bracket, thereby increasing the weight that the suspension device can support.

[0040] A washing machine includes a cabinet, a drum, and a suspension device as described above.

[0041] Preferably, there are multiple cylinders, and each cylinder is suspended from the box by the suspension device.

[0042] Preferably, there are multiple cylinders, adjacent cylinders are connected to each other, and the two cylinders at both ends are suspended from the box by the suspension device.

[0043] The positive and progressive effects of this utility model are as follows: by setting a washing support unit and a vibration isolation support unit made of elastic material, the two ends of the vibration isolation support unit are connected to the inner wall surface of the first support and the receiving cavity to support between the inner wall surface of the first support and the receiving cavity. Under any working condition, the vibration isolation support unit has a buffering and vibration reduction effect on the cylinder. By connecting the washing support unit to the first bracket, the washing support unit can move closer to or further away from the inner wall of the receiving cavity, and can switch between a first position and a second position. When the weight of the drum is small and the center of gravity is located at a preset position, the deformation of the vibration isolation support unit is small, and the washing support unit is located in the first position separated from the inner wall of the receiving cavity. 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 washing support unit is located in the second position abutting against the inner wall of the receiving cavity. At this time, the stiffness of the elastic support component is high, and the support effect on the drum is better. The vibration isolation support unit and the washing support unit simultaneously have the buffering and vibration reduction effect on the drum, thereby realizing the dynamic adjustment of the stiffness of the suspension device with the change of the weight of the drum, improving the buffering and vibration reduction effect of the suspension device under different operating conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine.

[0068] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0069] like Figures 1-6 As shown, this embodiment provides a suspension device 100 and a washing machine. The washing machine 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.

[0070] Specifically, such as Figures 1-3 As shown, the suspension device 100 includes a first bracket 1, a second bracket 2, and an elastic support assembly 3. The first end of the first bracket 1 is connected to the cylinder 300, and the second bracket 2 is connected to the housing 200. The second bracket 2 forms a receiving cavity 201, and the second end of the first bracket 1 extends into the receiving cavity 201. The elastic support assembly 3 is disposed in the receiving cavity 201 and includes a vibration-damping support unit 31 and a washing support unit 32 made of elastic material. The vibration-damping support unit 31 is supported between the second end of the first bracket 1 and the inner wall of the receiving cavity 201, and the washing support unit 32 is disposed at the second end of the first bracket 1. The second end of the first bracket 1 is configured to move closer to or further away from the second bracket 2 as the weight of the cylinder 300 changes, and can switch between a first position state and a second position state.

[0071] In the first position, the washing support unit 32 is separated from the inner wall of the receiving cavity 201; in the second position, the washing support unit 32 abuts against the inner wall of the receiving cavity 201. By providing the washing support unit 32 and the vibration isolation support unit 31, both ends of which are connected to the first support 1 and the inner wall of the receiving cavity 201, the vibration isolation support unit 31 provides cushioning and vibration reduction for the cylinder 300 under any operating condition. By connecting the washing support unit 32 to the first bracket 1, the washing support unit 32 can move closer to or further away from the inner wall of the receiving cavity 201, and can switch between a first position state and a second position state. When the weight of the drum 300 is small and the center of gravity is located at a preset position, the deformation of the vibration isolation support unit 31 is small, and the washing support unit 32 is located in the first position separated from the inner wall of the receiving cavity 201. At this time, the stiffness of the elastic support assembly 3 is low, and the drum 300 is only subjected to the buffering and vibration reduction effect of the vibration isolation support unit 31. When the weight of the drum 300 increases or the center of gravity shifts to a preset position, the deformation of the vibration isolation support unit 31 is large, and the washing support unit 32 is located in the second position that abuts against the inner wall of the receiving cavity 201. At this time, the elastic support component 3 has higher stiffness and better support for the drum 300. The vibration isolation support unit 31 and the washing support unit 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 operating conditions of the washing machine, and thus optimizing the vibration isolation rate of the washing machine.

[0072] In this embodiment, both the first position state and the second position state refer to position ranges. Specifically, the first position state occurs when the washing support unit 32 is separated from the second bracket 2 and supported above it; the second position state occurs when the washing support unit 32 is in contact with the second bracket 2. Figures 1-6 The washing support units 32 shown are all in the first position. Furthermore, the elastic support assembly 3 is made of rubber.

[0073] like Figures 3-5As shown, the vibration isolation support unit 31 includes a first support portion 311 and a second support portion 312 connected to each other. The first support portion 311 is sleeved on the outside of the second end of the first bracket 1, and the second support portion 312 is fitted against the inner wall of the receiving cavity 201. By sleeved on the outside of the second end of the first bracket 1, the connection area is increased, making the first bracket 1 more securely mounted on the first support portion 311. Furthermore, the fitting of the second support portion 312 against the inner wall of the receiving cavity 201 ensures a good match between the second support portion 312 and the inner wall of the receiving cavity 201, resulting in a large contact area. This allows the inner wall of the receiving cavity 201 to better bear the force, meaning the interaction area between the second support portion 312 and the receiving cavity 201 is large, resulting in more uniform force distribution on the receiving cavity 201, with relatively lower pressure and relatively greater weight bearing capacity.

[0074] It should be noted that the first support portion 311 and the second support portion 312 may be integrally formed or they may be separate from each other. The first support portion 311 has a hollow cylindrical structure, and the second end of the first bracket 1 also has a cylindrical structure to adapt to the first support portion 311. In addition, the width of the second support portion 312 along the axial direction of the receiving cavity 201 is not less than the width of the inner wall surface of the receiving cavity 201 along the axial direction of the receiving cavity 201. The width of the second end of the first bracket 1 along the axial direction of the receiving cavity 201 is not less than the width of the inner wall surface of the receiving cavity 201 along the axial direction of the receiving cavity 201, thereby increasing the connection area between the elastic support component 3 and the inner wall surface of the receiving cavity 201, and between the first bracket 1 and the support of the elastic support component 3, and improving the reliability of the connection.

[0075] In this embodiment, the washing support unit 32 is connected to the side of the first support portion 311 facing the inner wall of the receiving cavity 201, and protrudes relative to the inner wall of the first support portion 311 facing the receiving cavity 201. By connecting the washing support unit 32 to the side of the first support portion 311 facing the inner wall of the receiving cavity 201, and protruding relative to the inner wall of the first support portion 311 facing the receiving cavity 201, the travel distance between the position where the washing support unit 32 does not provide cushioning and the position where it provides cushioning is shortened, thus avoiding the phenomenon that the vibration isolation support unit 31 is severely deformed while the washing support unit 32 has not yet played its role.

[0076] Specifically, in this embodiment, there are two second support portions 312, which are symmetrically arranged about the first support portion 311. An installation space is formed between the first support portion 311 and the two second support portions 312, and the washing support unit 32 is disposed within this installation space. By providing two second support portions on both sides of the washing support unit 32, the support reliability of the vibration isolation support unit 31 is improved by increasing the number of second support portions. Furthermore, by placing the washing support unit 32 within the installation space, the structure of the suspension device 100 becomes more compact, reducing the overall size of the suspension device 100.

[0077] Of course, in other embodiments, the number of second support portions 312 may also be one or more. When there is only one second support portion 312, the second support portion 312 needs to comprehensively consider the components of its supporting force in the horizontal and vertical directions to determine the supporting angle, so as to improve the reliability of the support. When there are multiple second support portions 312, its supporting capacity is stronger, and it can be evenly arranged to make the force more balanced.

[0078] In this embodiment, as Figures 3-5 As shown, the suspension device 100 also includes a limiting member 4, which is disposed on the inner wall of the receiving cavity 201 and located on the movement path of the washing support unit 32 when switching between the first position state and the second position state. The limiting member 4 is used to cooperate with the washing support unit 32 so that the washing support unit 32 can move within a preset range. By setting the limiting member 4, which is located on the movement path of the washing support unit 32 when switching between the first position state and the second position state, and is used to cooperate with the washing support unit 32, the limiting member 4 can shorten the travel distance between the position of the washing support unit 32 that does not provide a buffering effect and the position that provides a buffering effect, thus avoiding the phenomenon that the vibration isolation support unit 31 is severely deformed while the washing support unit 32 has not yet played its role. At the same time, the limiting member 4 allows the washing support unit 32 to move within a preset range, thereby reducing the sway amplitude of the drum 300.

[0079] Specifically, in the second position state, the washing support unit 32 abuts against the limiting member 4. In the second position state, the washing support unit 32 abuts against the limiting member 4, thereby relying on the limiting member 4 to provide support.

[0080] In this embodiment, the limiting member 4 is also made of an elastic material, specifically rubber. By making the limiting member 4 also of an elastic material, the buffering and vibration damping capabilities of the suspension device 100 can be further improved. Furthermore, the elastic support assembly 3 and the limiting member 4 are integrally formed.

[0081] Of course, in other embodiments, the limiting member 4 can also be made of a rigid material, which also has the limiting effect, and will not be described in detail here.

[0082] In this embodiment, as Figure 3 As shown, the limiting member 4 has a limiting groove 402. In the second position state, the protruding washing support unit 32 is embedded in the limiting groove 402. By providing a limiting groove on the limiting member 4 to cooperate with the washing support unit 32, in the second position state, the washing support unit 32 is embedded in the limiting groove 402. After the washing support unit 32 abuts against the limiting member, better limiting can be achieved, the limiting effect is better, and the swaying amplitude of the drum can be further reduced.

[0083] Specifically in this embodiment, such as Figure 4 As shown, in this embodiment, there are two second support portions 312. The two second support portions 312 are configured such that the washing support unit 32 protruding relative to the first support portion 311 and the two second support portions 312 form two grooves 301. The limiting member 4 has two protrusions 401 on both sides of the limiting groove. When in the second position, the two protrusions 401 on both sides of the limiting member respectively engage with the two grooves 301. By providing two second support portions 312, the support effect of the elastic support assembly 3 can be improved. The formation of two grooves 301 on the elastic support assembly 3 and the provision of protrusions 401 on the limiting member 4 that engage with the two grooves 301 respectively further enhance the limiting effect of the limiting portion.

[0084] Of course, in other embodiments, when there is only one first support portion 311, the first support portion 311 can form a groove 301 with the washing support unit 32. In this case, the limiting member 4 only needs to be provided with one protrusion 401. Or in more embodiments, when multiple grooves 301 are formed between the first support portion 311 and the washing support unit 32, the limiting member 4 can also be provided with only one protrusion 401 to match any one of the grooves 301. This will not be elaborated here.

[0085] In this embodiment, as Figure 5 and Figure 6 As shown, the second support 2 includes a crossbeam 21 and an annular support 22. The two ends of the crossbeam 21 are connected to the housing 200. The annular support 22 is an annular structure with an opening. One end of the annular support 22 with the opening is connected to the crossbeam 21 and faces the housing 300. The annular support 22 and the crossbeam 21 form a receiving cavity 201. Furthermore, the vibration isolation support unit 31 is attached to the inner wall of the annular support 22 along its circumferential direction.

[0086] By connecting both ends of the crossbeam 21 to the housing 200, the crossbeam 21 can be stably connected to the housing 200. In addition, the open annular structure has two connection ends to the crossbeam 21, which makes the annular bracket 22 more stably connected to the crossbeam 21. Furthermore, the vibration isolation support unit 31 is attached to the inner wall of the annular bracket 22 along the circumferential direction, so that the vibration isolation support unit 31 can cover the entire inner wall of the annular bracket 22. Since it is an annular structure, the circumference of the inner wall of the annular bracket 22 is relatively long. That is to say, the above-mentioned arrangement further increases the working area of ​​the vibration isolation support unit 31 and the annular bracket 22, thereby increasing the weight that the suspension device 100 can support.

[0087] The two connecting ends of the open annular structure are connected to the crossbeam 21 by bolts.

[0088] In this embodiment, as Figures 1-2 As shown, the washing machine includes a drum connecting part 400 and two drums 300. The two ends of the drum connecting part 400 are respectively connected to the two drums 300. The drum connecting part 400 and the two drums 300 form a recessed portion. A hanging device 100 is disposed within the recessed portion. There is one hanging device 100. The connection point between the hanging device 100 and the drum connecting part 400 is located in the middle of the two drums 300, constituting a single-point central suspension. Specifically, as shown in the figure, the lower surface of the second part of the first bracket 1 is in close contact with the upper surface of the drum connecting part 400. The contact area between the two is relatively large, and two or more bolts can be used to connect the second part to the drum connecting part 400, thereby achieving a reliable connection between the first bracket 1 and the drums 300.

[0089] 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.

[0090] 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.

[0091] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. 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.
