Description

Technical Field

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

[0002] In traditional washing machines, the outer drum is connected to the casing via suspension springs and vibration dampers. The suspension springs act as elastic elements to isolate vibrations, while the vibration dampers primarily function as damping elements to attenuate vibrations. The combination of vibration dampers and suspension springs plays a significant role in isolating vibrations from the outer drum to the casing, while also reducing and attenuating the vibration amplitude of the outer drum. It is a core component of the washing machine.

[0003] However, the operating conditions of washing machines vary greatly at different stages of operation, and traditional suspension systems have the following problems:

[0004] 1) Fixed stiffness and damping parameters cannot meet dynamic requirements. During the washing stage, the drum contains clothes and water, resulting in a large overall mass. At this time, the suspension springs need to have high stiffness to support the weight and prevent significant drum displacement. During the spin-drying stage, only clothes remain in the drum, and the moisture content of the clothes gradually decreases, reducing the drum's mass. Simultaneously, the rotational speed increases, intensifying vibration. At this point, the suspension springs need to have relatively low stiffness to improve the vibration isolation rate of the suspension system. However, existing shock absorbers and suspension springs, once designed, have fixed stiffness and damping parameters that cannot be adjusted according to changes in operating conditions, making it difficult to meet ideal control requirements.

[0005] 2) The structure is not compact enough and occupies a large amount of space. The suspension springs and vibration dampers are distributed at the upper and lower ends of the cylinder, respectively, and connected to the housing. This layout makes the overall structure not compact enough, occupies a large amount of internal space in the housing, and affects the arrangement of other components.

[0006] 3) Existing technologies have the problem of low stiffness on the bearing side, which leads to excessive deformation on the vibration isolation bearing side and loss of bearing function.

[0007] 4) Existing technology has a problem of mismatch between the front and rear rigidity of the washing machine body, which causes the front of the drum to sink when installed, resulting in increased tensile stress on the front door seal and easy damage to the door seal. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the problem of low stiffness on the bearing side of the suspension device in the prior art, which leads to excessive deformation on the vibration isolation bearing side and loss of bearing function, as well as the problem of mismatch between the front and rear stiffness of the washing machine body, which causes the front of the drum to sink in the installation state, resulting in increased tensile stress on the front door seal and easy damage to the door seal. The present invention provides a suspension device and a washing machine containing the same.

[0009] The present invention solves the above-mentioned technical problems through the following technical solution:

[0010] A suspension device for suspending the drum of a washing machine from the casing of the washing machine, the suspension device comprising:

[0011] The first bracket, the first end of the first bracket is used to connect to the box body;

[0012] The second support, the first end of which is used to connect to the cylinder;

[0013] An elastic support assembly, the first end of which is connected to the second end of the first bracket, and the second end of which is connected to the second end of the second bracket, wherein the deformation of the second end of the elastic support assembly is configured to change with the gravity of the cylinder, so as to move closer to or further away from the first end of the elastic support assembly.

[0014] A bending-resistant bearing member is disposed at the second end of an elastic support assembly, wherein the bending-resistant bearing member is configured to act on the elastic support assembly and compress the second end of the elastic support assembly when the elastic support assembly deforms; and

[0015] The reinforcing member acts on the second end of the elastic support assembly to provide a force to the second end of the elastic support assembly that is opposite to the deformation direction of the first end of the elastic support assembly.

[0016] In this design, the elastic support assembly provides support and cushioning for the drum. The bending load-bearing component converts the bending of the second end of the elastic support assembly into a compressive load on the second end of the elastic support assembly, thereby improving the bending load-bearing capacity of the second end of the elastic support assembly. This helps prevent excessive deformation of the elastic support assembly on the load-bearing side of the washing machine, which could lead to loss of load-bearing function. Furthermore, the second end of the elastic support assembly moves closer to or further away from the first end as the weight of the drum changes. This design not only supports the drum when it becomes heavier but also provides good vibration isolation when it becomes lighter. The reinforcement component increases the stiffness and load-bearing capacity of the suspension device, preventing the front of the drum from sinking during installation, which could increase the tensile stress on the front door seal and cause it to be easily damaged.

[0017] Preferably, the elastic support assembly includes a first vibration isolation support part, a connecting part, and a second vibration isolation support part connected end to end in sequence. The first vibration isolation support part, the connecting part, and the second vibration isolation support part are made of elastic material. The first vibration isolation support part is connected to the first bracket, and the second vibration isolation support part is connected to the second bracket.

[0018] The bending bearing member is located on the side of the second vibration isolation support facing the first vibration isolation support.

[0019] In this solution, the elastic support assembly includes a first vibration isolation support, a connecting part, and a second vibration isolation support made of elastic material. This arrangement helps to reduce the vibration transmitted from the cylinder to the box and can provide flexible buffering for the vibration of the cylinder. In addition, the placement of the bending load-bearing member can first prevent the second vibration isolation support from deforming too much, and then prevent the first vibration isolation support and the connecting part from deforming too much. If the bending load-bearing member is placed on the first vibration isolation support or the connecting part, the second vibration isolation support may still easily deform too much on the bearing side of the cylinder.

[0020] Preferably, the second vibration isolation support has a first end connected to the second bracket and a second end away from the second bracket along the extending direction. Along the extending direction of the second vibration isolation support, the bending load-bearing member includes a first pressure plate, which is attached to the second vibration isolation support to press the second vibration isolation support from the side.

[0021] In this scheme, along the extension direction of the second vibration isolation support, the bending load-bearing member includes a first pressure plate. The first pressure plate is attached to the second vibration isolation support. The above arrangement makes the connection between the first pressure plate and the second vibration isolation support relatively tight, the connection area is large, and the force is relatively sufficient. The first pressure plate can also better restrict the deformation of the second vibration isolation support.

[0022] Preferably, the reinforcing member is made of an elastic material;

[0023] And / or,

[0024] The elastic support assembly includes a first vibration isolation support, a connecting part, and a second vibration isolation support connected end to end in sequence. The first vibration isolation support, the connecting part, and the second vibration isolation support are made of elastic material. The first vibration isolation support is connected to a first bracket, and the second vibration isolation support is connected to a second bracket. The first vibration isolation support, the connecting part, and the second vibration isolation support form an accommodating space. A reinforcing member is located within the accommodating space and connected between the first vibration isolation support and the second vibration isolation support.

[0025] In this design, the reinforcing member is made of elastic material. This arrangement increases the stiffness of the suspension device without making the stiffness too large and affecting the vibration isolation effect. The reinforcing member is located in the accommodating space and connected between the first vibration isolation support and the second vibration isolation support. This arrangement makes the positions of the various components of the suspension device more compact and saves space. Because the positions of the various components of the suspension device are more compact, the load-bearing capacity of the suspension device is stronger and more stable.

[0026] Preferably, the first end of the reinforcing member is located below the first bracket and abuts against the first bracket; the second end of the reinforcing member is located below the bending load-bearing member and abuts against the bending load-bearing member.

[0027] In this design, the aforementioned arrangement ensures that the reinforcing member acts on the most easily deformable part of the elastic support assembly, thereby enhancing the rigidity of the suspension device. Furthermore, the reinforcing member abuts against the first bracket and against the bending load-bearing member, making the suspension device more stable.

[0028] Preferably, the stiffness of the reinforcing member gradually decreases in the front-rear direction of the cylinder.

[0029] In this design, since the center of gravity of the cylinder is at the front and the weight at the front is large, the above-mentioned arrangement makes the elastic support component at the front of the cylinder have high stiffness and can bear a large weight, preventing the front of the cylinder from sinking during installation, which would increase the tensile stress on the front door seal and make the door seal easy to be damaged. Moreover, the weight at the rear of the cylinder is small, and the corresponding suspension device has low stiffness, resulting in good vibration isolation effect.

[0030] Preferably, the reinforcing member is a reinforcing plate, and at least one of the first plate surface of the reinforcing member facing away from the connecting part and the second plate surface near the connecting part is provided with multiple holes;

[0031] In particular, the size of multiple holes in the front-to-back direction of the cylinder is configured to gradually increase.

[0032] In this design, the arrangement of the holes makes the stiffness of the elastic support component at the front of the cylinder greater than that at the rear of the cylinder. This arrangement is ingenious and simple, and can also reduce the weight of the reinforcing components.

[0033] Preferably, the dimensions of the hole include radial dimensions and / or axial dimensions;

[0034] The axial dimension can be increased to the point where the hole passes through the reinforcing plate to form a through hole.

[0035] In this scheme, the above-mentioned arrangement can greatly reduce the stiffness of the reinforcing member on the elastic support assembly at the rear of the cylinder, thereby improving the vibration isolation effect of the suspension device.

[0036] Preferably, the reinforcing member and the elastic support assembly can be integrally formed.

[0037] In this solution, the one-piece molding design saves space occupied by the suspension device; in addition, the one-piece molding component is generally not easily damaged or broken into several parts when subjected to gravity, and it is also convenient to process.

[0038] This utility model also provides a washing machine, which includes a cabinet, a drum, and the aforementioned suspension device; wherein, there are multiple drums, each of which is suspended from the cabinet by the suspension device; or, there are multiple drums, adjacent drums are connected to each other, and the two drums at both ends are suspended from the cabinet by the suspension device.

[0039] In this design, adjacent cylinders are interconnected, and both cylinders at both ends are suspended from the box body by a suspension device, meaning that the suspension device can withstand a large amount of gravity.

[0040] The positive and progressive effects of this utility model are as follows: the elastic support component helps to support and buffer the drum; the anti-bending load-bearing component can convert the bending of the second end of the elastic support component into a compressive load on the second end of the elastic support component, thereby improving the anti-bending load-bearing capacity of the second end of the elastic support component and preventing excessive deformation of the elastic support component on the load-bearing side of the washing machine, thus losing its load-bearing function; in addition, the second end of the elastic support component moves closer to or further away from the first end as the weight of the drum changes. The above arrangement can support the drum when it becomes heavier and has a good vibration isolation effect when the drum becomes lighter; the reinforcement component can increase the rigidity of the suspension device and increase the load-bearing capacity of the suspension device, preventing the front of the drum from sinking in the installed state, which would increase the tensile stress on the front door seal and make the door seal easily damaged.

[0063] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0064] 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.

[0065] like Figure 1-3 As shown, this embodiment provides a suspension device 100, which is used to suspend the drum 400 of the washing machine 200 from the casing 300 of the washing machine 200. The suspension device 100 includes:

[0066] First bracket 1, the first end of the first bracket 1 is used to connect the box 300;

[0067] The second bracket 2, the first end of the second bracket 2 is used to connect the cylinder 400;

[0068] The elastic support component 3 has a first end connected to the second end of the first bracket 1 and a second end connected to the second end of the second bracket 2. The deformation of the second end of the elastic support component 3 is configured to change with the gravity of the cylinder 400, so as to move closer to or further away from the first end of the elastic support component 3.

[0069] A bending bearing member 4 is disposed at the second end of the elastic support assembly 3, wherein the bending bearing member 4 is configured to act on the elastic support assembly 3 and compress the second end of the elastic support assembly 3 when the elastic support assembly 3 deforms; and

[0070] The reinforcing member 5 acts on the second end of the elastic support assembly 3 to provide a force to the second end of the elastic support assembly 3 in the opposite direction to the deformation of the first end of the elastic support assembly 3.

[0071] In this embodiment, the elastic support component 3 is beneficial for supporting and buffering the drum 400. The bending bearing component 4 can convert the bending of the second end of the elastic support component 3 into a compressive load on the second end of the elastic support component 3 by the bending bearing component, thereby improving the bending bearing capacity of the second end of the elastic support component 3. This helps to prevent the elastic support component 3 on the bearing side of the washing machine 200 from deforming too much and losing its bearing function. In addition, the second end of the elastic support component 3 is closer to or further away from the first end of the drum 400 due to gravity changes. The above-mentioned arrangement can support the drum 400 when it becomes heavier and has a good vibration isolation effect when the drum 400 becomes lighter. The reinforcement component 5 can increase the rigidity of the suspension device 100 and increase the load-bearing capacity of the suspension device 100, preventing the front of the drum 400 from sinking in the installed state, which would lead to increased tensile stress on the front door seal and easy damage to the door seal.

[0072] It should be noted that when the washing machine 200 is in the washing mode, the drum 400 is very heavy, and the second end of the elastic support component 3 is far away from the first end of the elastic support component 3; when the washing machine 200 is in the washing mode, the drum 400 is light, and the second end of the elastic support component 3 is closer to the first end of the elastic support component 3 relative to the washing mode; in addition, multiple reinforcing members 5 can also be provided.

[0073] It should also be noted that the first bracket 1 includes a first mounting plate 11 and a crossbeam 12. The two ends of the crossbeam 12 are used to connect to the housing 300. The first end of the elastic support component 3 is located between the crossbeam 12 and the first mounting plate 11. The first mounting plate 11 threadedly connects the elastic support component 3 to the crossbeam 12. In addition, both the first mounting plate 11 and the second mounting plate 21 have mounting holes 34 for threaded connection.

[0074] The second bracket 2 includes a second mounting plate 21 and a mounting component 22. The second end of the elastic support component 3 is located between the second mounting plate 21 and the mounting component 22. The second mounting plate 21 is used to thread the second end of the elastic support component 3 onto the mounting component 22. The mounting component 22 is installed on the outer peripheral wall of the cylinder 400.

[0075] like Figure 3 As shown, the elastic support assembly 3 includes a first vibration isolation support part 31, a connecting part 33, and a second vibration isolation support part 32 connected end to end in sequence. The first vibration isolation support part 31, the connecting part 33, and the second vibration isolation support part 32 are made of elastic material. The first vibration isolation support part 31 is connected to the first bracket 1, and the second vibration isolation support part 32 is connected to the second bracket 2.

[0076] Among them, the bending bearing member 4 is disposed in the second vibration isolation support 32 on the side facing the first vibration isolation support 31.

[0077] In this embodiment, the elastic support assembly 3 includes a first vibration isolation support 31, a connecting part 33, and a second vibration isolation support 32 made of elastic material. This arrangement helps to reduce the vibration transmitted from the cylinder 400 to the box 300 and can provide flexible buffering for the vibration of the cylinder 400. In addition, the position of the bending bearing member 4 can first prevent the second vibration isolation support 32 from deforming too much, and then prevent the first vibration isolation support 31 and the connecting part 33 from deforming too much. If the bending bearing member 4 is provided on the first vibration isolation support 31 or the connecting part 33, the second vibration isolation support 32 will still easily deform too much on the bearing side of the cylinder 400.

[0078] It should be noted that the bending bearing member 4 can cover the entire side of the second vibration isolation support 32; in addition, the bending bearing member 4 can also be provided on the side of the first vibration isolation support 31 facing the second vibration isolation support 32; the bending bearing member 4 applies force in the opposite direction to the deformation direction of the second vibration isolation support 32.

[0079] like Figure 2 As shown, the second vibration isolation support 32 has a first end connected to the second bracket 2 and a second end away from the second bracket 2 along the extending direction. Along the extending direction of the second vibration isolation support 32, the bending bearing member 4 includes a first pressure plate, which is attached to the second vibration isolation support 32 to press the second vibration isolation support 32 from the side.

[0080] In this embodiment, along the extending direction of the second vibration isolation support 32, the bending bearing member 4 includes a first pressure plate. The first pressure plate is attached to the second vibration isolation support 32. The above arrangement makes the connection between the first pressure plate and the second vibration isolation support 32 relatively tight, the connection area is large, and the force is relatively sufficient. The first pressure plate can also better restrict the deformation of the second vibration isolation support 32.

[0081] It should be noted that the first pressure plate and the second bracket 2 can be designed to be integrally formed.

[0082] The reinforcing member 5 is made of an elastic material; and / or, the elastic support assembly 3 includes a first vibration isolation support 31, a connecting part 33, and a second vibration isolation support 32 connected end to end in sequence. The first vibration isolation support 31, the connecting part 33, and the second vibration isolation support 32 are made of an elastic material. The first vibration isolation support 31 is connected to the first bracket 1, and the second vibration isolation support 32 is connected to the second bracket 2. The first vibration isolation support 31, the connecting part 33, and the second vibration isolation support 32 form an accommodating space. The reinforcing member 5 is located in the accommodating space and connected between the first vibration isolation support 31 and the second vibration isolation support 32.

[0083] In this embodiment, the reinforcing member 5 is made of an elastic material. This arrangement increases the stiffness of the suspension device 100 without making the stiffness of the suspension device 100 too large and affecting the vibration isolation effect. The reinforcing member 5 is located in the accommodating space and connected between the first vibration isolation support 31 and the second vibration isolation support 32. This arrangement makes the positions of the components of the suspension device 100 more compact and saves space. Because the positions of the components of the suspension device 100 are more compact, the load-bearing capacity of the suspension device 100 is stronger and more stable.

[0084] It should be noted that the reinforcing component 5 can be a rubber component.

[0085] like Figure 2 As shown, the first end of the reinforcing member 5 is located below the first bracket 1 and abuts against the first bracket 1; the second end of the reinforcing member 5 is located below the bending bearing member 4 and abuts against the bending bearing member 4.

[0086] In this embodiment, the above-mentioned arrangement causes the reinforcing member 5 to act on the part of the elastic support assembly 3 that is most prone to deformation, so as to enhance the rigidity of the suspension device 100; in addition, the reinforcing member 5 abuts against the first bracket 1 and the reinforcing member 5 abuts against the bending bearing member 4, making the suspension device 100 more stable.

[0087] The stiffness of the reinforcing member 5 gradually decreases in the front-rear direction of the cylinder 400.

[0088] In this embodiment, since the center of gravity of the cylinder 400 is at the front and the weight at the front is large, the above-mentioned arrangement makes the elastic support component 3 have high stiffness at the front of the cylinder 400 and bear a large weight, preventing the front of the cylinder 400 from sinking in the installed state, which would increase the tensile stress on the front door seal and make the door seal easy to be damaged. Moreover, the weight at the rear of the cylinder 400 is small, and the corresponding suspension device 100 has low stiffness and good vibration isolation effect.

[0089] like Figure 3 As shown, the reinforcing member 5 is a reinforcing plate, and at least one of the first pressure plate surface away from the connecting part 33 and the second plate surface near the connecting part 33 is provided with a plurality of holes 51; wherein, in the front-rear direction of the cylinder 400, the size of the plurality of holes 51 is configured to gradually increase.

[0090] In this embodiment, the arrangement of the hole 51 makes the stiffness of the elastic support component 3 at the front of the cylinder 400 greater than that at the rear of the cylinder 400. This arrangement is quite ingenious and can also reduce the weight of the reinforcing member 5.

[0091] It should be noted that, in the front-to-back direction of the cylinder 400, the reinforcing member 5 can also be thicker at the front and thinner at the back, in order to control the stiffness of the reinforcing member 5 at the front and back.

[0092] like Figure 3As shown, the dimensions of the hole 51 include radial and / or axial dimensions; wherein the axial dimension can be increased to the point that the hole 51 passes through the reinforcing plate to form a through hole 51.

[0093] In this embodiment, the above-mentioned arrangement can greatly reduce the stiffness of the reinforcing member 5 on the elastic support assembly 3 at the rear of the cylinder 400, thereby improving the vibration isolation effect of the suspension device 100.

[0094] It should be noted that hole 51 can be a square hole, a round hole, etc.

[0095] Specifically, in this embodiment, the hole 51 is a circular hole, which is provided on the first plate surface of the reinforcing member 5 away from the connecting part 33. In the front-rear direction of the cylinder 400, the radial and axial dimensions of the multiple holes 51 are configured to gradually increase, and the axial dimension can be increased to the point that the hole 51 passes through the reinforcing plate to form a through hole 51.

[0096] like Figure 3 As shown, the reinforcing member 5 and the elastic support component 3 can be integrally formed.

[0097] The aforementioned one-piece design saves space occupied by the suspension device 100; in addition, one-piece components are generally not easily damaged or broken into several parts when subjected to gravity, and are also easy to process.

[0098] This embodiment also provides a washing machine 200, which includes a cabinet 300, a drum 400, and the aforementioned suspension device 100; wherein there are multiple drums 400, each of which is suspended from the cabinet 300 by the suspension device 100; or, there are multiple drums 400, adjacent drums 400 are connected to each other, and the two drums 400 at both ends are suspended from the cabinet 300 by the suspension device 100.

[0099] In this embodiment, such as Figure 1 As shown, the washing machine 200 has two drums 400 connected together, and each drum 400 is suspended from the cabinet 300 by a suspension device 100. Specifically, the side walls of the drums 400 are suspended from the inner wall of the cabinet 300 by the suspension device 100.

[0100] In other embodiments, the washing machine 200 may have three or more drums 400; adjacent drums 400 are connected to each other, and the two drums 400 at both ends are suspended from the cabinet 300 by the suspension device 100, that is to say, the suspension device 100 can withstand a large amount of gravity.

[0101] The washing machine 200 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the washing machine 200 to perform corresponding operations, thereby realizing intelligent control of the washing machine 200 and improving the user experience.
