Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a vibration damping support device and a washing machine. Background Technology

[0002] Traditional washing machines suspend the drum from the cabinet using suspension springs and vibration dampers. The suspension springs act as elastic elements for vibration isolation, while the vibration dampers act as damping elements to attenuate vibrations. The suspension springs and vibration dampers are connected to the upper and lower ends of the outer drum and the cabinet, respectively. This structure is loose and not compact enough, taking up a lot of space inside the cabinet and affecting the arrangement of other components. At the same time, the traditional suspension system requires a separate component (suspension spring and vibration damper) to achieve the functions of vibration isolation and vibration attenuation, resulting in a large number of components and complexity. Traditional suspension systems, especially those that make up the vibration dampers, have many components, and both ends are connected to the drum and cabinet by pins. During the spin cycle, the relative movement of these components generates significant structural noise.

[0003] Existing technologies also use rubber materials as damping elements to play a damping role. However, rubber materials are prone to creep and permanent deformation under long-term loads, which leads to a smaller gap between the outer cylinder and nearby components, increasing the risk of impact between the outer cylinder and nearby components during operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of existing vibration damping devices, such as loose structure, large volume, and easy deformation of damping elements, and to provide a vibration damping support device and a washing machine.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides a vibration damping support device, which is used to connect the drum of a washing machine to the casing of the washing machine. The vibration damping support device is disposed on both sides of the drum and supports the drum. The vibration damping support device includes:

[0007] A damping support assembly, one end of which is connected to the cylinder and the other end of which is connected to the box, wherein the damping support assembly is configured to deform in response to changes in the weight of the cylinder;

[0008] A preload assembly, one end of which is connected to the housing and the other end of which is connected to the damping support assembly, wherein the preload assembly is capable of providing an upward tension to the damping support assembly.

[0009] In this design, the vibration damping support device includes a damping support assembly and a pre-tensioning assembly. The damping support assembly connects the washing machine's drum and cabinet, providing support and deforming with changes in the drum's weight, thus isolating and reducing vibrations. The pre-tensioning assembly connects the cabinet and the damping support assembly at both ends, providing upward tension. When the damping support assembly undergoes creep after long-term use, the pre-tensioning assembly pulls it upward, preventing permanent deformation and sinking of the drum that could reduce the gap between the drum and nearby components, thus minimizing the risk of impact during operation. Furthermore, the vibration damping support device achieves vibration isolation and reduction with only two components: the damping support assembly and the pre-tensioning assembly. This reduces the number of parts, eliminates the need for traditional shock absorbers and suspension springs, resulting in a more compact structure that significantly reduces space occupation within the cabinet. It also avoids the relative movement of traditional rigidly connected components, preventing structural noise generated during component operation.

[0010] Preferably, the pre-tightening assembly includes an elastic element and a connector. The elastic element has a pre-tightening force. One end of the elastic element is connected to the housing, and the other end of the elastic element is connected to the connector. The connector is connected to the damping support assembly, and the connector is shaped to match the damping support assembly.

[0011] In this solution, the elastic element provides preload. One end of the elastic element is connected to the housing, and the other end is connected to the connector. The connector is used to connect to the damping support assembly, and the connector and the damping support assembly are matched in shape. This allows the preload of the preload of the preload assembly to be applied to the damping support assembly more effectively, which in turn makes it easier to apply an upward pulling force to the damping support assembly.

[0012] Preferably, the damping support assembly has a through clearance groove, and the end of the elastic element away from the housing passes through the clearance groove and is connected to the connector. The connector fits into the damping support assembly, and the damping support assembly can move relative to the elastic element along the extension direction of the clearance groove.

[0013] In this solution, by allowing the damping support assembly to move relative to the elastic element along the extension direction of the clearance groove, the damping support assembly and the elastic element will move relative to each other when the washing machine is running. The clearance groove allows them to have enough space for relative movement, making the vibration damping support device more flexible and further improving the vibration damping effect.

[0014] Preferably, the connector is a crossbar, the elastic element is connected to the outer periphery of the crossbar, and the outer periphery of the crossbar is in contact with the damping support assembly.

[0015] In this solution, by setting the connector as a crossbar, the outer periphery of the crossbar is fitted with the damping support assembly, thereby increasing the contact area between the damping support assembly and the crossbar, making the force distribution more stable and uniform, making the connection between the damping support assembly and the elastic element more stable, and improving the application effect of the pre-tightening force, thus further enhancing the vibration reduction effect.

[0016] Preferably, the damping support assembly includes a first connecting part, a second connecting part, and a support body, wherein the first connecting part is used to connect the cylinder, and the second connecting part is used to connect the box body;

[0017] The first connecting part and the second connecting part are respectively connected to the two ends of the support body, and the pre-tightening component is connected to the support body. The first connecting part and the second connecting part are in a non-collinear state.

[0018] The connection positions of the pretensioning component and the damping support component are located above the first connection portion and the second connection portion.

[0019] In this design, by arranging the first and second connecting parts non-collinearly, the supporting body between them can better receive the tension from the pre-tightening assembly. This facilitates the second connecting part applying upward tension to the cylinder, resulting in better overall stress distribution of the damping support assembly. Simultaneously, it saves internal space within the housing, making the structure more compact. Furthermore, by positioning the pre-tightening assembly and the damping support assembly above the first and second connecting parts, it is easier for the pre-tightening assembly to provide upward pre-tightening force, while also saving internal space within the housing.

[0020] Preferably, the vibration damping support device further includes a first support frame for connection to the cylinder body, wherein the connecting surface of the first support frame to the cylinder body matches the shape of the outer side wall of the cylinder body, the first connecting part is connected to the first support frame, and the connection part of the first connecting part to the first support frame matches the shape of the first support frame.

[0021] In this solution, by setting a first support frame and matching the connecting surface of the first support frame to the cylinder with the shape of the outer wall of the cylinder, the first support frame can be more stably connected to the cylinder. The first connecting part is connected to the first support frame, and the connection part between the first connecting part and the first support frame is matched with the shape of the first support frame. This allows the weight change of the cylinder to be better transmitted to the first connecting part through the first support frame, making the overall structure more stable and further improving the vibration isolation and damping effect.

[0022] Preferably, the vibration damping support device further includes a second support frame for connecting to the housing, the second connecting part being connected to the second support frame, and the connection portion of the second connecting part and the second support frame matching the shape of the second support frame;

[0023] The second support frame includes a first part and a second part arranged sequentially in an upward direction. The lower end of the first part is used to connect to the box body, the upper end of the first part is connected to the lower end of the second part, and the upper end of the second part is used to connect to the box body. From the lower end to the upper end of the first part, the first part extends into the interior of the box body, and from the upper end to the lower end of the second part, the second part extends into the interior of the box body. The second connecting part is connected to the first part and fits against the first part.

[0024] And / or, the vibration damping support device further includes a third support frame, one end of which is used to connect to the housing, and the other end of which is used to connect to the end of the preload assembly away from the damping support assembly.

[0025] In this solution, by connecting the second connecting part to the second support frame and matching the shape of the connection between the second connecting part and the second support frame, the damping support assembly can be more stably connected to the box body. At the same time, it can extend the distance between the damping support assembly and the inner wall of the box body, so that the cylinder body is farther away from the inner wall of the box body, thus avoiding collision between the cylinder body and the box body when it moves.

[0026] From the lower end to the upper end of the first part, the first part extends into the interior of the housing, and simultaneously from the upper end to the lower end of the second part, the second part extends into the interior of the housing. This causes the entire second support frame to extend into the interior of the housing, thereby increasing the distance between the damping support assembly and the inner wall of the housing, and further distancing the cylinder from the inner wall. By connecting the second support frame to the first part and ensuring it fits snugly against the first part, the stability of the connection between the second connecting part and the second support frame is further enhanced.

[0027] Similarly, the vibration damping support device is also equipped with a third support frame for connecting the pretensioning component to the housing. By setting the third support frame, the distance between the pretensioning component and the inner wall of the housing can be extended, and the stability of the third support frame connecting to the housing can also be increased.

[0028] Preferably, the vibration damping support device further includes a mounting bracket, which is used to connect to the inner side wall of the housing and fits against the housing, and the second support frame and the third support frame are connected to the mounting bracket.

[0029] In this solution, by setting a mounting bracket that fits snugly against the inner wall of the enclosure, and connecting the second and third support brackets to the mounting bracket, the load-bearing area of ​​the enclosure is increased, making it easier for the forces of the second and third support brackets to be transmitted to the mounting bracket and then to the enclosure, thus making the connection between the second and third support brackets more stable.

[0030] This utility model also provides a washing machine, which includes a cabinet, a drum, and the aforementioned vibration damping support device.

[0031] Preferably, there are two cylinders, and the vibration damping support devices are symmetrically arranged on both sides of the cylinders; or,

[0032] There are at least three cylinders, and adjacent cylinders are connected to each other. The two cylinders at both ends are connected to the box body through the vibration damping support device.

[0033] In this design, when there are two cylinders, the vibration damping support devices are symmetrically arranged on both sides of the cylinder, allowing them to bear force evenly from both sides of the cylinder, further improving vibration isolation and damping effects. When there are at least three cylinders, adjacent cylinders are interconnected, with the two cylinders at each end connected to the housing via vibration damping support devices. The weight of multiple cylinders is applied to the vibration damping support devices at both ends, thus ensuring good vibration isolation and resistance even with multiple cylinders.

[0034] The positive and progressive effects of this utility model are as follows:

[0035] The vibration damping support device includes a damping support assembly and a pre-tensioning assembly. The damping support assembly connects the washing machine's drum and cabinet, providing support and deforming with changes in the drum's weight, thus isolating and reducing vibrations. The pre-tensioning assembly connects to the cabinet and the damping support assembly at both ends, providing upward tension. When the damping support assembly undergoes creep after long-term use, the pre-tensioning assembly pulls it upward, preventing permanent deformation and sinking of the drum that could reduce the gap between the drum and nearby components, thus reducing the risk of impact during operation. Furthermore, the vibration damping support device achieves vibration isolation and reduction with only two components: the damping support assembly and the pre-tensioning assembly. This reduces the number of parts, eliminates the need for traditional shock absorbers and suspension springs, resulting in a more compact structure that significantly reduces space occupied in the cabinet. It also avoids the relative movement of traditional rigidly connected components, preventing structural noise generated during component operation. Attached Figure Description

[0061] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0062] like Figure 1 and Figure 2 As shown, this embodiment provides a washing machine 100, which includes a cabinet 110, a drum 120, and a vibration damping support device 130.

[0063] like Figure 3 and Figure 4 As shown, the vibration damping support device 130 is used to connect the drum 120 of the washing machine 100 to the housing 110 of the washing machine 100. The vibration damping support device 130 is provided on both sides of the drum 120 and supports the drum 120. The vibration damping support device 130 includes a damping support assembly 230 and a pre-tightening assembly 240.

[0064] One end of the damping support assembly 230 is connected to the cylinder 120, and the other end is connected to the housing 110. The damping support assembly 230 is configured to deform in response to changes in the gravity of the cylinder 120. One end of the preload assembly 240 is connected to the housing 110, and the other end is connected to the damping support assembly 230. The preload assembly 240 provides an upward tension to the damping support assembly 230.

[0065] The vibration damping support device 130 connects the drum 120 and the cabinet 110 of the washing machine 100 via the damping support assembly 230. The damping support assembly 230 provides support and deforms with the weight of the drum 120, thus isolating and reducing vibration. The pre-tensioning assembly 240 connects the cabinet 110 and the damping support assembly 230 at both ends, providing an upward pulling force to the damping support assembly 230. When the damping support assembly 230 undergoes creep after long-term use, the pre-tensioning assembly 240 can pull it upward, preventing permanent deformation and sinking of the drum 120 that could reduce the gap between the drum 120 and nearby components, thereby reducing the risk of impact to the drum 120 during operation. Meanwhile, the vibration damping support device 130 achieves vibration isolation and damping effects with only two parts: the damping support component 230 and the pretensioning component 240. This reduces the number of parts, eliminates the traditional method of vibration damper and suspension spring, and makes the structure more compact. It significantly reduces the space occupied by the housing 110, avoids the relative movement of traditional hard-connected structural components, and avoids structural noise generated by component operation.

[0066] like Figure 3 and Figure 4As shown, the pretensioning assembly 240 includes an elastic element 241 and a connecting element 242. The elastic element 241 has a pretensioning force. One end of the elastic element 241 is connected to the housing 110, and the other end of the elastic element 241 is connected to the connecting element 242. The connecting element 242 is connected to the damping support assembly 230, and the connecting element 242 and the damping support assembly 230 are shaped to match. The elastic element 241 provides a pretensioning force. One end of the elastic element 241 is connected to the housing 110, and the other end is connected to the connecting element 242. The damping support assembly 230 is connected through the connecting element 242, and the shapes of the connecting element 242 and the damping support assembly 230 are matched, so that the pretensioning force of the pretensioning assembly 240 can be better applied to the damping support assembly 230, which is more conducive to applying an upward pulling force to the damping support assembly 230. In this embodiment, the elastic element 241 is a pretensioning spring. In other embodiments, other specific structures of the elastic element 241 that are considered suitable by those skilled in the art can also be selected.

[0067] The damping support assembly 230 has a through clearance groove 234. One end of the elastic member 241, away from the housing 110, passes through the clearance groove 234 and connects to the connector 242. The connector 242 fits against the damping support assembly 230, allowing the damping support assembly 230 to move relative to the elastic member 241 along the extension direction of the clearance groove 234. By configuring the damping support assembly 230 to move relative to the elastic member 241 along the extension direction of the clearance groove 234, when the washing machine 100 is running, the damping support assembly 230 and the elastic member 241 will move relative to each other. The clearance groove 234 provides sufficient space for this relative movement, increasing the flexibility of the vibration damping support device 130 and further improving the vibration damping effect. In this embodiment, the clearance groove 234 is a through hole penetrating the damping support assembly 230. In other embodiments, the clearance groove 234 can also be configured as other structures deemed suitable by those skilled in the art.

[0068] The connector 242 is a crossbar, and the elastic element 241 is connected to the outer periphery of the crossbar. The outer periphery of the crossbar is in contact with the damping support assembly 230. By setting the connector 242 as a crossbar, and the outer periphery of the crossbar being in contact with the damping support assembly 230, the contact surface between the damping support assembly 230 and the crossbar is larger, the force is more stable and even, the connection between the damping support assembly 230 and the elastic element 241 is more stable, the application effect of the pre-tightening force is better, and the vibration reduction effect is further improved.

[0069] The damping support assembly 230 includes a first connecting portion 231, a second connecting portion 232, and a support body 233. The first connecting portion 231 is used to connect the cylinder 120, and the second connecting portion 232 is used to connect the housing 110. The two ends of the support body 233 are respectively connected to the first connecting portion 231 and the second connecting portion 232. A pre-tensioning assembly 240 is connected to the support body 233. The first connecting portion 231 and the second connecting portion 232 are in a non-collinear state. By making the first connecting portion 231 and the second connecting portion 232 non-collinear, the support body 233 between the first connecting portion 231 and the second connecting portion 232 can be better subjected to the tension of the pre-tensioning assembly 240, which is more conducive to the second connecting portion 232 applying an upward tension to the cylinder 120. The overall stress-bearing effect of the damping support assembly 230 is better, and it can also save space inside the housing 110, making the structure more compact.

[0070] The connection points of the pretensioning assembly 240 and the damping support assembly 230 are located above the first connecting portion 231 and the second connecting portion 232. By placing the connection points of the pretensioning assembly 240 and the damping support assembly 230 above the first connecting portion 231 and the second connecting portion 232, it is easier for the pretensioning assembly 240 to provide upward pretensioning force, while saving space inside the housing 110.

[0071] In this embodiment, the damping support assembly 230 has a V-shaped structure, with the first connecting portion 231 and the second connecting portion 232 arranged opposite to each other, thereby facilitating the movement of the first connecting portion 231 and the second connecting portion 232 and improving the vibration reduction effect. In other embodiments, those skilled in the art can choose other suitable specific shapes for the damping support assembly 230.

[0072] The vibration damping support device 130 also includes a first support frame 300 for connection to the cylinder 120. The connecting surface of the first support frame 300 to the cylinder 120 matches the shape of the outer wall of the cylinder 120. A first connecting part 231 is connected to the first support frame 300, and the connection portion of the first connecting part 231 to the first support frame 300 matches the shape of the first support frame 300. By setting the first support frame 300 and matching the connecting surface of the first support frame 300 to the outer wall of the cylinder 120, the first support frame 300 can be more stably connected to the cylinder 120. By connecting the first connecting part 231 to the first support frame 300 and matching the connection portion of the first connecting part 231 to the first support frame 300, the weight change of the cylinder 120 can be better transmitted to the first connecting part 231 through the first support frame 300. The overall structure is more stable, further improving the vibration isolation and damping effect.

[0073] The vibration damping support device 130 also includes a second support frame 400 for connection to the housing 110. A second connecting portion 232 is connected to the second support frame 400, and the connection portion of the second connecting portion 232 to the second support frame 400 matches the shape of the second support frame 400. The second support frame 400 includes a first portion 410 and a second portion 420 arranged sequentially in an upward direction. The lower end of the first portion 410 is used to connect to the housing 110, the upper end of the first portion 410 is connected to the lower end of the second portion 420, and the upper end of the second portion 420 is used to connect to the housing 110. From the lower end to the upper end of the first portion 410, the first portion 410 extends into the housing 110. From the upper end to the lower end of the second portion 420, the second portion 420 extends into the housing 110. The second connecting portion 232 is connected to the first portion 410 and fits against the first portion 410. The vibration damping support device 130 also includes a third support frame 500, one end of which is used to connect to the housing 110, and the other end of which is used to connect to the end of the pretensioning assembly 240 away from the damping support assembly 230.

[0074] By connecting the second connecting part 232 to the second support frame 400 and matching the shape of the connection between the second connecting part 232 and the second support frame 400, the damping support assembly 230 can be more securely connected to the housing 110. Simultaneously, the distance between the damping support assembly 230 and the inner wall of the housing 110 is extended, making the cylinder 120 farther from the inner wall of the housing 110, thus preventing collisions between the cylinder 120 and the housing 110 during movement. Extending the first part 410 from its lower end to its upper end into the housing 110, and extending the second part 420 from its upper end to its lower end into the housing 110, the second support frame 400 extends entirely into the housing 110, further extending the distance between the damping support assembly 230 and the inner wall of the housing 110, making the cylinder 120 farther from the inner wall of the housing 110. By connecting the second support frame 400 to and fitting it into the first part 410, the stability of the connection between the second connecting part 232 and the second support frame 400 is further improved. Similarly, the vibration damping support device 130 is also provided with a third support frame 500 for connecting the pretensioning component 240 to the housing 110. By providing the third support frame 500, the distance between the pretensioning component 240 and the inner wall of the housing 110 can be extended, and the stability of the connection between the third support frame 500 and the housing 110 can also be increased.

[0075] In this embodiment, the first connecting portion 231 is provided with a first mounting hole 235, and the first connecting portion 231 is threadedly connected to the first support frame 300 through the first mounting hole 235. Similarly, the second connecting portion 232 is provided with a second mounting hole 236, and the second connecting portion 232 is threadedly connected to the second support frame 400 through the second mounting hole 236. In other embodiments, other connection methods deemed suitable by those skilled in the art may also be selected.

[0076] The first connecting part 231 bends toward the first support frame 300 at the position where it connects with the first support frame 300, and the second connecting part 232 bends toward the second support frame 400 at the position where it connects with the second support frame 400, which helps to extend the distance between the inner surfaces of the cylinder 120 and the box 110, and also increases the stability of the connection.

[0077] like Figure 3 and Figure 4 As shown, the shape of the third support frame 500 is similar to that of the second support frame 400, and its middle part also extends to the inside of the box 110. Similarly, it can extend the distance between the damping support assembly 230 and the inner wall of the box 110, so that the cylinder 120 is farther away from the inner wall of the box 110.

[0078] The vibration damping support device 130 also includes a mounting bracket 600, which is connected to and fits snugly against the inner wall of the housing 110. The second support frame 400 and the third support frame 500 are connected to the mounting bracket 600. By providing the mounting bracket 600, which fits snugly against the housing 110, on the inner wall of the housing 110, and connecting the second support frame 400 and the third support frame 500 to the mounting bracket 600, the load-bearing area of ​​the housing 110 is increased. This facilitates the transmission of force from the second support frame 400 and the third support frame 500 to the mounting bracket 600, and subsequently to the housing 110, making the connection between the second support frame 400 and the third support frame 500 more stable. The second support frame 400 and the third support frame 500 can be welded to the mounting bracket 600 or threaded onto it; those skilled in the art can choose according to actual needs. The mounting bracket 600 can be welded to the inner wall of the housing 110, or other connection methods deemed suitable by those skilled in the art can be selected.

[0079] In this embodiment, there are two cylinders 120, and the vibration damping support devices 130 are symmetrically arranged on both sides of the cylinders 120. When there are two cylinders 120, the vibration damping support devices 130 are symmetrically arranged on both sides of the cylinders 120, so that the vibration damping support devices 130 can be evenly subjected to force from both sides of the cylinders 120, thereby further improving the vibration isolation and damping effect.

[0080] In other embodiments, there may be one cylinder 120, with two vibration damping support devices 130 symmetrically arranged on both sides of the cylinder 120. The number of cylinders 120 may also be at least three, with adjacent cylinders 120 interconnected, and the two cylinders 120 at each end connected to the housing 110 via vibration damping support devices 130. When there are at least three cylinders 120, adjacent cylinders 120 are interconnected, and the two cylinders 120 at each end are connected to the housing 110 via vibration damping support devices 130. The weight of the multiple cylinders 120 is applied to the vibration damping support devices 130 at both ends, thereby achieving better vibration isolation and resistance even with multiple cylinders 120.

[0081] The vibration damping support device 130 in this embodiment can be used in ordinary washing machines or smart washing machines. The smart washing machine has a smart voice control module, which includes 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 of using the smart appliance.
