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) Suspension springs and vibration dampers are generally distributed at the upper and lower ends of the cylinder and connected to the housing. Overall, the structure is not compact enough, occupies a large amount of internal space in the housing, and affects the arrangement of other components. At the same time, in traditional suspension systems, vibration isolation and vibration damping each require a component to achieve the function (suspension spring and vibration damper), resulting in a large number of components and complexity.

[0005] 2) Traditional suspension systems, especially those that make up the shock absorbers, have many components, and both ends are connected to the cylinder and box body by pins. The relative movement between the connecting parts under dehydration conditions will generate structural noise, which is not conducive to the noise reduction of the whole machine. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing suspension system, which has a complex structure and is not conducive to noise reduction of the whole machine, and to provide a suspension device and a washing machine containing 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, the first end of which is used to connect to the housing;

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

[0011] An elastic support assembly, the elastic support assembly being made of an elastic material, the elastic support assembly including a vibration isolation support part and a washing support part, the vibration isolation support part having a box end and a cylinder end along the direction from the box side to the cylinder side, the box end and the cylinder end being respectively connected to the second end of the first bracket and the second end of the second bracket, the vibration isolation support part having at least one bending part from the box end to the cylinder end;

[0012] The washing support is disposed on the vibration isolation support;

[0013] The cylindrical end of the vibration isolation support is configured to move closer to or further away from the box end of the vibration isolation support as the weight of the cylindrical body changes, and can switch between a first position state and a second position state.

[0014] When in the first position state, the washing support is separated from the second end of the first bracket and the second end of the second bracket;

[0015] When in the second position, the washing support abuts against the second end of the first bracket or / and the second end of the second bracket.

[0016] In this design, the elastic support assembly comprises a vibration-damping support and a washing support, both made of elastic material. This arrangement helps reduce vibrations transmitted from the drum to the cabinet, and the bends save space between the suspension unit and the drum. The drum end of the vibration-damping support is configured to move closer to or further away from the cabinet end of the vibration-damping support as the drum's weight changes. This means the suspension unit can flexibly buffer changes in the drum's weight, preventing rigid breakage. In the first position, the washing support is separated from the second ends of both the first and second supports. At this point, the drum load is relatively small. For example, during the spin cycle, the weight on the first and second supports decreases, the overall drum mass is smaller, and the rotation speed gradually increases, resulting in greater vibration. The separation of the first and second supports from the washing support reduces the stiffness of the suspension unit, thus achieving a good vibration isolation effect. In the second position, the drum is under greater load, such as during the washing cycle. The weight on the first and second supports increases, and the washing support abuts against the second end of the first and / or second support, increasing the stiffness of the suspension device to support the larger load and achieve better damping and vibration reduction. Furthermore, this suspension device achieves vibration isolation and reduction through the vibration isolation support and washing support, reducing the number of parts and eliminating the need for traditional shock absorbers and spring suspensions. The structure is more compact, significantly reducing the space occupied by the drum and avoiding the relative movement of traditional rigidly connected components, thus preventing structural noise generated during component operation.

[0017] Preferably, the vibration isolation support has an S-shaped structure and includes a first bent portion, an intermediate connecting portion, and a second bent portion connected in sequence;

[0018] The first bent portion is located at the end of the box body and is connected to the first bracket, and the second bent portion is located at the end of the cylinder body and is connected to the second bracket;

[0019] The washing support portion is provided on the side of the intermediate connecting portion facing the first bracket and / or on the side of the intermediate connecting portion facing the second bracket;

[0020] When in the second position, the washing support abuts against the corresponding first bracket and / or second bracket.

[0021] In this design, the vibration isolation support has an S-shaped structure, which is relatively simple and helps to simplify the overall structure of the suspension device. When in the second position, the washing support abuts against the corresponding first and / or second brackets, and both the vibration isolation support and the washing support function simultaneously. This results in greater stiffness of the suspension device, enabling it to reliably support larger loads. Furthermore, the washing support is positioned on the intermediate connecting part, utilizing the space between the intermediate connecting part and the first and / or second bending parts, improving space utilization and further enhancing the structural compactness of the elastic support assembly.

[0022] Preferably, a first washing support portion is provided on the side of the intermediate connecting portion facing the first bracket, and a second washing support portion is provided on the side of the intermediate connecting portion facing the second bracket;

[0023] When in the second position, the first washing support abuts against the second end of the first bracket, and the second washing support abuts against the second end of the second bracket; the first washing support and the second washing support are misaligned along the horizontal direction.

[0024] In this design, washing support parts are provided on both sides of the middle connecting part and are staggered. On the one hand, the staggered arrangement of the first and second washing support parts can reduce the space occupied in the horizontal direction, which can reduce the space requirements between the box and the drum. On the other hand, the two washing support parts can work simultaneously or only one of them needs to work, which helps to further ensure the reliability of the suspension device.

[0025] Preferably, the box end of the vibration isolation support is engaged with the first bracket, and the cylindrical end of the vibration isolation support is engaged with the second bracket.

[0026] In this solution, the connection between the vibration isolation support and the box and cylinder is achieved by engaging the two ends of the vibration isolation support with the first bracket and the second bracket respectively. The connection method is simple and reliable, and it also helps to simplify the overall structure of the suspension device.

[0027] Preferably, the first bracket has a first slot, and the box end of the vibration isolation support is adapted to the shape of the first slot and embedded in the first slot;

[0028] And / or, the second bracket has a second slot, and the cylindrical end of the vibration isolation support is adapted to the shape of the second slot and embedded in the second slot.

[0029] In this solution, the connection between the vibration isolation support and the box and cylinder is achieved by inserting the two ends of the vibration isolation support into the first slot and the second slot respectively. The connection method is simple and reliable, and it also helps to simplify the overall structure of the suspension device.

[0030] Preferably, the vibration isolation support is an S-shaped structure and includes a first bent part, an intermediate connecting part and a second bent part connected in sequence. The first bent part is located at the box end and the end of the first bent part is inserted into the first slot from top to bottom. The second bent part is located at the cylinder end and the end of the second bent part is inserted into the second slot from bottom to top.

[0031] In this design, the side where the second bend is located is the cylinder side, which is the side where the vibration isolation support is most affected by the load. The end of the second bend is inserted into the second slot from bottom to top. The greater the load on the cylinder, the closer the second bracket will be to the second bend, thus enabling a tighter and more reliable connection, which helps to ensure the reliability of the connection between the vibration isolation support and the cylinder.

[0032] Preferably, the first bracket has a first stress-relieving portion extending outward from the edge of the first slot, and the second bracket has a second stress-relieving portion extending outward from the edge of the second slot;

[0033] The first stress relief portion is attached to the inner side of the first bending portion, and the second stress relief portion is attached to the inner side of the second bending portion.

[0034] Preferably, the first stress relief portion extends at most to the end face of the first bent portion near the end of the intermediate connecting portion, and the second stress relief portion extends at most to the end face of the second bent portion near the end of the intermediate connecting portion.

[0035] In this design, the first stress-relieving part increases the contact area between the first bending part and the first slot, thus reducing stress concentration at the contact point between the vibration isolation support and the first slot. Correspondingly, the second stress-relieving part increases the contact area between the second bending part and the second slot, further reducing stress concentration at the contact point between the vibration isolation support and the second slot.

[0036] In this solution, the above-mentioned structural configuration ensures that neither the first stress relief part nor the second stress relief part extends beyond the corresponding bending part. This reduces stress concentration without excessively increasing the lateral stiffness of the elastic support component, which would hinder elastic deformation. As a result, the deformation reliability of the elastic support component is guaranteed, allowing the suspension device to function reliably.

[0037] Preferably, the vibration isolation support and the washing support are integrally formed.

[0038] In this design, the aforementioned structural configuration simplifies the structure of the suspension device through a one-piece molding, and also helps to reduce the space occupied by the suspension device. Furthermore, the one-piece molded component is generally less prone to damage or breakage into several parts when subjected to the significant gravity of the cylinder, thus ensuring the overall reliability of the suspension device.

[0039] This utility model also provides a washing machine, which includes a cabinet, a drum and the above-mentioned suspension device;

[0040] There are multiple cylindrical bodies, each of which is suspended from the box body by the suspension device; or,

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

[0042] In this scheme, depending on the actual layout requirements, each of the multiple cylinders can be connected to the box via a suspension device, or only the cylinders at both ends can be connected to the box via a suspension device. The layout is flexible, as long as the reliable suspension of the cylinders can be guaranteed.

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

[0044] In this application, the elastic support assembly includes a vibration-damping support and a washing support, both made of elastic material. This design helps reduce vibrations transmitted from the drum to the cabinet, and the bends save space between the suspension device and the cabinet. The drum end of the vibration-damping support is configured to move closer to or further away from the cabinet end of the vibration-damping support as the weight of the drum changes. This means the suspension device can flexibly buffer changes in the drum's weight, preventing rigid breakage. In the first position, the washing support is separated from the second ends of both the first and second supports. At this time, the load on the drum is relatively small. For example, when the washing machine is in spin-drying mode, the weight on the first and second supports decreases, the overall drum mass is smaller, and the rotation speed gradually increases, resulting in greater vibration. Since both the first and second supports are separated from the washing support, the stiffness of the suspension device is reduced, thus achieving a good vibration-damping effect. When in the second position, the load on the drum is relatively large, such as when the washing machine is in the washing state. The gravity on the first and second supports increases, and the washing support part abuts against the second end of the first support and / or the second end of the second support, which increases the stiffness of the suspension device to support the larger load and achieve a better damping and vibration reduction effect.

[0045] In addition, the suspension device achieves vibration isolation and damping effects through the vibration isolation support and the washing support, reducing the number of parts and eliminating the traditional method of suspension with shock absorbers and hanging springs. The structure is more compact, significantly reducing the space occupied by the housing, avoiding the relative movement of traditional rigid connection structural components, and avoiding structural noise generated by the operation of components.

[0075] 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.

[0076] like Figures 1 to 9As shown, this embodiment provides a hanging device 100 and a washing machine 200 including the hanging device 100. In addition to the hanging device 100, the washing machine 200 also includes a cabinet 300 and a drum 400. Figures 1 to 5 As shown, there are two cylinders 400 connected together by a cylinder connecting part 500, and each cylinder 400 is suspended from the box body 300 by a suspension device 100. In other alternative embodiments, there may be multiple cylinders 400, in which case each cylinder 400 may be suspended from the box body 300 by a suspension device 100. In other alternative embodiments, there may be multiple cylinders 400, in which case adjacent cylinders 400 are connected to each other, and the two cylinders 400 at both ends are suspended from the box body 300 by a suspension device 100.

[0077] In the washing machine 200, each of the multiple drums 400 can be connected to the cabinet 300 via the suspension device 100, or only the two drums 400 at both ends can be connected to the cabinet 300 via the suspension device 100, which is flexible and can be arranged as long as the reliable suspension of the drums 400 is met.

[0078] Specifically regarding the suspension device 100, such as Figures 1 to 9 As shown, the suspension device 100 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 a first bracket 10, a second bracket 20, and an elastic support assembly 30. The first end of the first bracket 10 is used to connect to the casing 300, and the first end of the second bracket 20 is used to connect to the drum 400. The elastic support assembly 30 is made of elastic material and includes a vibration-damping support portion 40 and a washing support portion 50. Along the direction from the casing 300 side to the drum 400 side, the vibration-damping support portion 40 has a casing 300 end and a drum 400 end, which are respectively connected to the second ends of the first bracket 10 and the second bracket 20. From the casing 300 end to the drum 400 end, the vibration-damping support portion 40 has at least one bent portion. A washing support 50 is disposed on a vibration isolation support 40. The drum 400 end of the vibration isolation support 40 is configured to move closer to or further away from the housing 300 end of the vibration isolation support 40 as the weight of the drum 400 changes, and can switch between a first position state and a second position state. In the first position state, the washing support 50 is separated from the second ends of both the first support 10 and the second support 20. In the second position state, the washing support 50 abuts against the second ends of the first support 10 and / or the second end of the second support 20.

[0079] In this embodiment, the elastic support assembly 30 includes a vibration-damping support portion 40 and a washing support portion 50, made of elastic material. This arrangement helps to reduce the vibration transmitted from the drum 400 to the housing 300, and the bending portion helps to save the space occupied by the suspension device 100 between the housing 300 and the drum 400. The drum 400 end of the vibration-damping support portion 40 is configured to move closer to or further away from the housing 300 end of the vibration-damping support portion 40 as the weight of the drum 400 changes. In other words, the suspension device 100 can flexibly buffer changes in the weight of the drum 400 to prevent rigid breakage. In the first position, the washing support 50 is separated from the second ends of the first bracket 10 and the second bracket 20. At this time, the load on the drum 400 is relatively small. For example, when the washing machine 200 is in spin-drying mode, the gravity on the first bracket 10 and the second bracket 20 decreases. The overall mass of the drum 400 is small, but the rotational speed gradually increases, resulting in greater vibration. Since the first bracket 10 and the second bracket 20 are separated from the washing support 50, the stiffness of the suspension device 100 decreases, thus achieving a good vibration isolation effect. In the second position, the load on the drum 400 is larger. For example, when the washing machine 200 is in washing mode, the gravity on the first bracket 10 and the second bracket 20 increases. The washing support 50 abuts against the second ends of the first bracket 10 and / or the second bracket 20, increasing the stiffness of the suspension device 100 to support the larger load and achieving a better damping and vibration reduction effect.

[0080] In addition, the suspension device 100 achieves vibration isolation and damping effects through the vibration isolation support part 40 and the washing support part 50, reducing the number of parts, eliminating the traditional method of vibration damper and suspension spring, making the structure more compact, significantly reducing the space occupied by the housing 300, avoiding the relative movement of traditional hard-connected structural components, and avoiding structural noise generated by component operation.

[0081] As a preferred setting, such as Figures 1 to 3 , Figures 6 to 8 As shown, there are two bending sections. Specifically, the vibration isolation support section 40 has an S-shaped structure and includes a first bending section 401, an intermediate connecting section 402, and a second bending section 403 connected in sequence. The first bending section 401 is located at the end of the housing 300 and is connected to the first bracket 10. The second bending section 403 is located at the end of the cylinder 400 and is connected to the second bracket 20. A washing support section 50 is provided on the side of the intermediate connecting section 402 facing the first bracket 10 and / or the side of the intermediate connecting section 402 facing the second bracket 20. When in the second position, the washing support section 50 abuts against the corresponding first bracket 10 and / or second bracket 20.

[0082] The vibration isolation support 40 has an S-shaped structure, which is relatively simple and helps to simplify the overall structure of the suspension device 100. In the second position, the washing support 50 abuts against the corresponding first bracket 10 and / or second bracket 20. Both the vibration isolation support 40 and the washing support 50 function simultaneously, resulting in greater stiffness of the suspension device 100, thus enabling it to reliably support larger loads. Furthermore, the washing support 50 is located on the intermediate connecting part 402, which utilizes the space between the intermediate connecting part 402 and the first bending part 401 and / or the second bending part 403, improving space utilization and further enhancing the structural compactness of the elastic support assembly 30.

[0083] It should be noted that in this embodiment, a washing support portion 50 is provided on the side of the intermediate connecting portion 402 facing the first bracket 10, and in the second position state, the washing support portion 50 abuts against the first bracket 10. In other alternative embodiments, the washing support portion 50 may only be provided on the side of the intermediate connecting portion 402 facing the second bracket 20, and in the second position state, the washing support portion 50 abuts against the second bracket 20.

[0084] Accordingly, in other alternative embodiments, washing support portions 50 may be provided on both the side of the intermediate connecting portion 402 facing the first bracket 10 and the side of the intermediate connecting portion 402 facing the second bracket 20. For ease of description, the washing support portion 50 on the side of the intermediate connecting portion 402 facing the first bracket 10 is referred to as the first washing support portion, and the washing support portion 50 on the side of the intermediate connecting portion 402 facing the second bracket 20 is referred to as the second washing support portion. The first and second washing support portions are staggered in the horizontal direction. In the second position state, the first washing support portion abuts against the second end of the first bracket 10, and the second washing support portion abuts against the second end of the second bracket 20.

[0085] In the above alternative embodiments, washing support parts 50 are provided on both sides of the intermediate connecting part 402 and are arranged in a staggered manner. On the one hand, the staggered arrangement of the first washing support part and the second washing support part can reduce the space occupied in the horizontal direction, that is, it can reduce the space requirement between the box 300 and the drum 400. On the other hand, by providing two washing support parts 50, both washing support parts 50 can work at the same time, or only one of them needs to work, which is conducive to further ensuring the reliability of the suspension device 100.

[0086] In other alternative embodiments, the bending portion can be one, three, or more. When there is only one bending portion, both ends of the vibration isolation support 40 can be inserted into the corresponding slots from top to bottom or from bottom to top. When there are three or more bending portions, the two ends of the vibration isolation support 40 can be inserted into the corresponding slots from top to bottom or from bottom to top, depending on the actual situation. Regarding the connection between the cylindrical end 400 of the vibration isolation support 40 and the second bracket 20, if the cylindrical end 400 is inserted into the corresponding slot from top to bottom, a corresponding threaded fastener must be added. In this case, the threaded fastener is the main load-bearing component. Specifically, corresponding connection holes are provided on the vibration isolation support 40 and the cylindrical end 400. For the connection between the second bending portion 403 and the cylindrical end 400, the threaded fastener simply passes through the connection holes on the second bending portion 403 and the cylindrical end 400.

[0087] Regarding the connection method between the vibration isolation support 40 and the housing 300 and the cylinder 400, as a preferred configuration, the housing 300 end of the vibration isolation support 40 can be configured to engage with the first bracket 10, and the cylinder 400 end of the vibration isolation support 40 can be configured to engage with the second bracket 20. This configuration achieves the connection between the vibration isolation support 40 and the housing 300 and the cylinder 400 by engaging both ends of the vibration isolation support 40 with the first bracket 10 and the second bracket 20 respectively. This connection method is simple and reliable, and also simplifies the overall structure of the suspension device 100.

[0088] As a preferred setting, such as Figures 1 to 5 , Figure 7 and Figure 9 As shown, the first bracket 10 has a first slot 103, and the box body 300 end of the vibration isolation support part 40 is adapted to the shape of the first slot 103 and embedded in the first slot 103. The second bracket 20 has a second slot 201, and the cylindrical body 400 end of the vibration isolation support part 40 is adapted to the shape of the second slot 201 and embedded in the second slot 201.

[0089] Here, the connection with the housing 300 and the cylinder 400 is achieved by inserting both ends of the vibration isolation support 40 into the first slot 103 and the second slot 201, respectively. The connection method is simple and reliable, and it also helps to simplify the overall structure of the suspension device 100. Of course, in other alternative embodiments, the slots can also be provided on the vibration isolation support 40, and corresponding protrusions for engaging with the slots can be provided on the housing 300 and the cylinder 400.

[0090] In the specific connection process, the end of the first bent portion 401 is inserted into the first slot 103 from top to bottom, and the end of the second bent portion 403 is inserted into the second slot 201 from bottom to top.

[0091] The side where the second bend 403 is located is the side of the cylinder 400, which is the side of the vibration isolation support 40 that is more affected by the load. The end of the second bend 403 is inserted into the second slot 201 from bottom to top. The greater the load on the cylinder 400, the closer the second bracket 20 will be to the second bend 403, so that the connection can be tighter and more reliable, which is conducive to ensuring the reliability of the connection between the vibration isolation support 40 and the cylinder 400.

[0092] It should be noted that, in order to further improve the reliability of the connection between the vibration isolation support 40 and the housing 300 and the cylinder 400, threaded fasteners can be further provided for reinforcement on the basis of the above-mentioned snap-fit ​​connection. Corresponding connection holes are provided on the vibration isolation support 40, housing 300, and cylinder 400. For the connection between the first bent portion 401 and the housing 300, the threaded fastener simply passes through the connection hole on the first bent portion 401 and the housing 300. For the connection between the second bent portion 403 and the cylinder 400, the threaded fastener simply passes through the connection hole on the second bent portion 403 and the cylinder 400. The threaded fasteners serve as auxiliary reinforcement components and are not primary load-bearing components.

[0093] Furthermore, the first bracket 10 has a first stress-relieving portion 104 extending outward from the edge of the first slot 103, and the second bracket 20 has a second stress-relieving portion 202 extending outward from the edge of the second slot 201. The first stress-relieving portion 104 is fitted with the inner side of the first bending portion 401, and the second stress-relieving portion 202 is fitted with the inner side of the second bending portion 403. Here, the provision of the first stress-relieving portion 104 increases the contact area at the contact point between the first bending portion 401 and the first slot 103, thereby reducing stress concentration at the contact point between the vibration-damping support portion 40 and the first slot 103. Correspondingly, the provision of the second stress-relieving portion 202 increases the contact area at the contact point between the second bending portion 403 and the second slot 201, thereby reducing stress concentration at the contact point between the vibration-damping support portion 40 and the second slot 201.

[0094] It should be noted that, as a preferred configuration, the first stress-relieving part 104 extends at most to the end face of the first bending part 401 near the intermediate connecting part 402, and the second stress-relieving part 202 extends at most to the end face of the second bending part 403 near the intermediate connecting part 402. Neither the first stress-relieving part 104 nor the second stress-relieving part 202 extends beyond their respective bending parts. This reduces stress concentration without excessively increasing the lateral stiffness of the elastic support assembly 30, which could hinder elastic deformation. Therefore, the deformation reliability of the elastic support assembly 30 is ensured, allowing the suspension device 100 to function reliably.

[0095] Furthermore, the vibration isolation support 40 and the washing support 50 are integrally formed. The integral design simplifies the structure of the suspension device 100 and also helps to reduce the space occupied by the suspension device 100. In addition, the integrally formed components are generally not easily damaged or broken into several parts when subjected to the large gravity of the cylinder 400, which helps to ensure the overall reliability of the suspension device 100.

[0096] As an example, both the vibration isolation support 40 and the washing support 50 are made of rubber. In other alternative embodiments, the vibration isolation support 40 and the washing support 50 may also be made of other elastic materials.

[0097] Furthermore, such as Figure 9 As shown, the first bracket 10 includes a first connecting plate 101 and a second connecting plate 102. The first connecting plate 101 is used to fit and connect to the inner wall of the housing 300. The second connecting plate 102 has a bent structure and forms a first slot 103 with the first connecting plate 101. A first stress-relieving part 104 extends outward from the edge of the second connecting plate 102. The first stress-relieving part 104 has a bent structure, and its shape is adapted to the shape of the first bent part 401.

[0098] To further simplify the structure, as a preferred configuration, the first stress relief part 104 and the second connecting plate 102 are configured as an integrally formed structure.

[0099] Correspondingly, the structure of the second support 20 can be basically the same as that of the first support 10. The main difference is that the specifications of the first connecting plate are different. The first connecting plate of the second support 20 is connected to the cylinder 400, and its specifications and shape can be adapted to the wall surface of the cylinder 400.

[0100] Specifically, in this embodiment, such as Figure 5 As shown, the second bracket 20 does not include the first connecting plate mentioned above, but instead forms a second slot 201 directly with the wall of the cylinder 400 through the second connecting plate.

[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 to perform corresponding operations, thereby realizing the intelligent control of the washing machine 200 and improving the user experience.
