Description

Technical Field

[0001] The present application relates to the field of vibration reduction technology, and in particular to a support device, a base structure and a household appliance. Background Art

[0002] With the continuous advancement of technology, household appliances have entered more and more households and become an indispensable part of every household.

[0003] In the relevant technical field, many household appliances are prone to vibration and vibration noise during operation, which affects the user experience. Utility Model Content

[0004] The embodiments of the present application provide a support device, a base structure, and a household appliance, which are designed to enable the elastic member to generate compressive deformation or tensile deformation along a first direction when the appliance body generates vibration during operation to absorb the vibration generated by the appliance body, thereby reducing the vibration transmission from the appliance body to the placement surface, thereby reducing vibration noise, and improving the user experience.

[0005] An embodiment of the present application provides a support device suitable for a base structure, the base structure includes a chassis, the support device includes an elastic member, a connecting member and a hard support member, one end of the elastic member is used to connect to the chassis, and the elastic member is an energy-absorbing structural member made of a flexible material; the connecting member extends along a first direction, and one end of the connecting member passes through the elastic member and is used to connect to the chassis, the hard support member is connected to the other end of the elastic member, and the connecting member can move relative to the hard support member; wherein the elastic member can produce compression deformation and tensile deformation along the first direction to reduce vibration of the chassis.

[0006] Based on the above embodiment, when the appliance body generates vibration during operation, the elastic member can generate compressive and tensile deformation along a first direction to absorb the vibration generated by the appliance body, thereby reducing the transmission of vibration from the appliance body to the placement surface, and further reducing vibration noise. Furthermore, the connector can limit the deformation direction of the elastic member, allowing the elastic member to maintain deformation along the first direction, thereby reducing the probability of damage to the elastic member and extending the service life of the elastic member. This ensures that the elastic member can absorb the vibration generated by the appliance body, thereby reducing the vibration noise of the household appliance and improving the user experience.

[0007] In some embodiments, the hard support member has a receiving groove and an avoidance hole connected to the receiving groove, the connecting member is passed through the avoidance hole, and the end of the connecting member away from the chassis is located in the receiving groove.

[0008] Based on the above embodiment, the end of the connecting member away from the chassis is arranged in the accommodating groove, so that when the household appliance vibrates, the chassis can drive the connecting member to move, so that the end of the connecting member away from the chassis can move in the accommodating groove. Compared with the movement of the connecting member outside the hard support member, the end of the connecting member away from the chassis can move in the accommodating groove, thereby reducing the overall volume of the support device to reduce the space occupied by the support device.

[0009] In some embodiments, the hard support member has a support surface, which is arranged on a side of the hard support member away from the chassis. The support surface is used to support the support device. Along the first direction, there is a first dimension L1 between the end of the connecting member away from the chassis and the support surface, and L1 satisfies: 3mm≤L1≤5mm.

[0010] Based on the above embodiment, the support surface is provided on the placement surface. Since 3mm≤L1≤5mm, the probability of the connector colliding with the placement surface when the elastic member deforms can be reduced, thereby reducing the probability of collision noise generated by the connector colliding with the support surface, thereby improving the user experience. Furthermore, since the space occupied by the connector within the rigid support member can be reduced, the rigid support member can be made smaller, and the overall support device can be made smaller, which in turn reduces the space occupied by the household appliance, thereby improving the production, manufacturing, and transportation efficiency of the household appliance.

[0011] If L1 is less than 3 mm, when the elastic member is deformed, the connector may easily collide with the placement surface, which may easily generate collision noise, resulting in a louder overall noise in the household appliance and affecting the user experience.

[0012] If L1>5mm, the connecting part will occupy a larger space in the hard support part, which will cause the hard support part to be higher, resulting in a larger overall volume of the support device, and causing the household appliance to occupy a larger space, affecting the production and transportation efficiency of the household appliance.

[0013] In some embodiments, when the elastic member is deformed along the first direction, the deformation amount of the elastic member is greater than or equal to 15% and less than or equal to 30%.

[0014] Based on the above embodiment, when the elastic member is deformed along the first direction, the deformation of the elastic member is greater than or equal to 15% and less than or equal to 30%, ensuring that the elastic performance of the elastic member is good, thereby improving the vibration reduction effect of the elastic member on the chassis, and further improving the vibration reduction effect of the support device on the electrical appliance body.

[0015] If the deformation of the elastic part is less than 15% when the elastic part is deformed along the first direction, it indicates that the hardness of the elastic part is relatively large, and the deformation amount that the elastic part can continue to deform is relatively small, resulting in poor elastic performance of the elastic part, resulting in a smaller deformation amount that the elastic part can produce, resulting in poor vibration reduction effect of the elastic part on the chassis, resulting in poor vibration reduction effect of the support device on the electrical appliance body, and easy generation of vibration noise.

[0016] If the deformation of the elastic part is greater than 30% when the elastic part is deformed along the first direction, it indicates that the hardness of the elastic part is relatively small. When the deformation of the elastic part is greater than 30%, the deformation amount that the elastic part can continue to deform is relatively small, resulting in poor elastic performance of the elastic part, resulting in a smaller deformation amount that the elastic part can produce, resulting in poor vibration reduction effect of the elastic part on the chassis, resulting in poor vibration reduction effect of the support device on the electrical appliance body, and easy generation of vibration noise.

[0017] In some embodiments, the elastic member includes an elastic main body and a first limiting portion, one end of the elastic main body is connected to the hard support member, and the other end is used to connect to the chassis; the first limiting portion is arranged on the side of the elastic main body facing the hard support member; the hard support member includes a supporting main body and a second limiting portion, the second limiting portion is arranged on the side of the supporting main body facing the elastic main body, and is connected to the first limiting portion; wherein, one of the first limiting portion and the second limiting portion is a protrusion, and the other of the first limiting portion and the second limiting portion is a groove, the protrusion is protruded in the groove, and abuts against the groove wall of the groove.

[0018] Based on the above embodiment, by connecting the first limiting portion and the second limiting portion, the contact area between the elastic member and the hard supporting member can be increased, thereby improving the connection stability between the elastic member and the hard supporting member.

[0019] In some embodiments, the elastic member and the hard support member are formed as one piece.

[0020] Based on the above embodiments, the elastic part can be formed into one piece with the hard support part through a two-color injection molding process to improve the connection stability between the elastic part and the hard support part, and also to improve the assembly efficiency of the elastic part and the hard support part, thereby improving the assembly efficiency of the support device.

[0021] In some embodiments, the rigid support member is a damping rigid support member.

[0022] Based on the above embodiment, the hard support member can be a damping hard support member, which can reduce the probability of the hard support member displacing on the placement surface; and because it is a hard support member, it is also convenient to move the hard support member, thereby realizing the movement of household appliances, so as to facilitate the installation, maintenance and repair of household appliances.

[0023] An embodiment of the present application also provides a base structure, including a chassis and a supporting device, the chassis has a limiting structure; the elastic member is connected to the chassis, and the end of the connecting member away from the hard support member is connected to the chassis, and the hard support member cooperates with the limiting structure so that the hard support member drives the chassis to move along a second direction, and the second direction is perpendicular to the first direction.

[0024] Based on the above embodiment, when the rigid support member is moved in the second direction, the rigid support member cooperates with the limiting structure, enabling the rigid support member to drive the chassis to move in the second direction, thereby moving the household appliance. Furthermore, because the rigid support member can drive the chassis to move, the connector is protected from significant radial forces, thereby reducing the probability of damage to the connector. This extends the service life of the connector, and consequently, the service life of the base structure.

[0025] In some embodiments, the limiting structure includes a limiting groove, the elastic member is connected to the bottom of the limiting groove, and at least a portion of the hard support member can extend into the limiting groove.

[0026] Based on the above embodiment, at least a portion of the hard support member can extend into the limiting groove, so that when the hard support member is moved along the second direction, the hard support member can abut against the groove wall of the limiting groove to drive the chassis to move along the second direction, thereby allowing the household appliance as a whole to move along the second direction.

[0027] In some embodiments, along the first direction, the length of the hard support member extending into the limiting groove is a second dimension L2, and L2 satisfies: 3mm≤L2≤5mm.

[0028] Based on the above embodiment, L2 satisfies: 3mm≤L2≤5mm, indicating that the deformation of the elastic member is greater than or equal to 15% and less than or equal to 30%, thereby ensuring that the elastic performance of the elastic member is good, thereby improving the vibration reduction effect of the elastic member on the chassis, and further improving the vibration reduction effect of the support device on the main body of the appliance. In addition, L2 satisfies: 3mm≤L2≤5mm, which can reduce the probability of the hard support member disengaging from the limit groove when moving the hard support member in the second direction, thereby ensuring that the hard support member can drive the chassis to move in the second direction, thereby allowing the household appliance as a whole to move in the second direction; it can also prevent the connecting member from being subjected to large radial forces, thereby reducing the probability of damage to the connecting member, so that the connecting member can have a longer service life, and thereby the base structure can have a longer service life.

[0029] If L2 is less than 3mm, when the hard support part is moved along the second direction, the probability of the hard support part being easily disengaged from the limiting groove will result, resulting in the hard support part being unable to drive the chassis to move along the second direction. In addition, when the hard support part is disengaged from the limiting groove, the connecting part is subjected to a large radial force, resulting in a high probability of damage to the connecting part, affecting the service life of the connecting part and shortening the service life of the base structure. L2 less than 3mm can also indicate that the deformation of the elastic part is less than 15%, indicating that the hardness of the elastic part is large, and the deformation that the elastic part can continue to deform is small, resulting in poor elastic performance of the elastic part, resulting in a small deformation that the elastic part can produce, resulting in poor vibration reduction effect of the elastic part on the chassis, resulting in poor vibration reduction effect of the support device on the electrical main body, and easy generation of vibration noise.

[0030] If L2>5mm, it indicates that the deformation of the elastic part is greater than 30%, indicating that the hardness of the elastic part is relatively small. When the deformation of the elastic part is greater than 30%, the deformation that the elastic part can continue to deform is relatively small, resulting in poor elastic performance of the elastic part, resulting in a smaller deformation that the elastic part can produce, resulting in poor vibration reduction effect of the elastic part on the chassis, resulting in poor vibration reduction effect of the support device on the electrical body, and easy to generate vibration noise.

[0031] In some embodiments, the hard support member is spaced apart from the wall of the limiting groove.

[0032] Based on the above embodiment, the hard support part is spaced apart from the groove wall of the limiting groove so that when the household appliance generates vibration, the chassis can move relative to the hard support part, thereby preventing the vibration of the chassis from being transmitted to the hard support part, thereby reducing the probability of the hard support part generating vibration noise.

[0033] In some embodiments, along the second direction, the spacing dimension between the hard support member and the groove wall of the limiting groove is a third dimension L3, and L3 satisfies: 0.5mm≤L3≤5mm.

[0034] Based on the above embodiment, L3 satisfies the following condition: 0.5mm≤L3≤5mm. This reduces the probability of collision between the groove wall of the retaining groove and the hard support member when the household appliance vibrates, thereby reducing the probability of collision noise. Furthermore, when the chassis moves relative to the hard support member, the retaining groove and the hard support member cooperate to limit the distance the chassis moves relative to the hard support member, preventing the connector from being subjected to large radial forces and reducing the probability of damage to the connector. This extends the service life of the connector and, in turn, the service life of the base structure.

[0035] If L3 is less than 0.5 mm, the distance between the groove wall of the limit groove and the hard support member is closer. When the household appliance vibrates, the groove wall of the limit groove is likely to collide with the hard support member, resulting in a higher probability of generating collision noise.

[0036] If L3>5mm, the distance between the groove wall of the limit groove and the hard support part will be longer. When the household appliance vibrates, the chassis will move a longer distance relative to the hard support part, causing the connecting part to bear a larger radial force and a higher probability of damage to the connecting part.

[0037] In some embodiments, the chassis also includes a first positioning portion, which is arranged at the bottom of the limiting groove; the elastic member includes an elastic main body portion and a second positioning portion, and the elastic main body portion is connected to the chassis; the second positioning portion is connected to the elastic main body portion and is cooperatively connected to the first positioning portion; wherein, one of the first positioning portion and the second positioning portion is a protrusion, and the other of the first positioning portion and the second positioning portion is a groove, and the protrusion is protruded in the groove.

[0038] Based on the above embodiment, the first positioning portion is connected in cooperation with the second positioning portion, so that the contact area between the elastic member and the chassis can be increased, thereby improving the connection stability between the elastic member and the chassis.

[0039] An embodiment of the present application further provides a household appliance, comprising a base structure and an appliance body, wherein the appliance body is connected to a side of the chassis away from the supporting device.

[0040] Based on the above embodiment, when the electrical appliance body generates vibration during operation, the supporting device can reduce vibration for the electrical appliance body.

[0041] Based on the support device of the present application, when the main body of the appliance generates vibration during operation, the elastic member can generate compression deformation and tension deformation along a first direction to absorb the vibration generated by the main body of the appliance, thereby reducing the transmission of vibration from the main body of the appliance to the placement surface, and further reducing vibration noise. Furthermore, the connection member can limit the deformation direction of the elastic member, so that the elastic member can maintain deformation along the first direction, reducing the probability of damage to the elastic member, and thus extending the service life of the elastic member. This ensures that the elastic member can absorb the vibration generated by the main body of the appliance, thereby reducing the vibration noise of the household appliance and improving the user experience.

[0047] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0048] Please refer to Figure 1 An embodiment of the present application provides a household appliance 1, comprising an appliance body 11 and a base structure 2, wherein the base structure 2 is connected to the bottom of the appliance body 11 and is used to support the appliance body 11.

[0049] It is understandable that the electrical appliance body 11 is one of a dishwasher, a water purifier, a food processor, a refrigerator, and a clothes processing device. In the embodiment of the present application, the form of the electrical appliance body 11 is not limited.

[0050] Please refer to Figure 1 and Figure 2 In one embodiment, the base structure 2 includes a chassis 21 and a supporting device 3. The chassis 21 is connected to the electrical appliance body 11. The supporting device 3 is connected to the chassis 21 and is arranged on a side of the chassis 21 away from the electrical appliance body 11.

[0051] It is understood that the connection method between the chassis 21 and the appliance body 11 includes, but is not limited to, screwing, clamping, welding, or gluing. In the embodiment of the present application, there is no specific limitation on the connection method between the chassis 21 and the appliance body 11. It is understood that the chassis 21 can be circular, rectangular, or other polygonal, and in the embodiment of the present application, there is no specific limitation on the shape of the chassis 21. Considering the overall aesthetics of the household appliance 1, the shape of the chassis 21 can be adapted to the shape of the appliance body 11.

[0052] It is understandable that the support device 3 can be arranged at the corners of the chassis 21. Exemplarily, when the chassis 21 is rectangular, four support devices 3 can be provided, and the four support devices 3 are arranged at the four corners of the rectangle, so that the chassis 21 is evenly stressed, thereby reducing the probability of damage to the chassis 21, and can also uniformly absorb the vibrations generated by the electrical body 11, thereby improving the vibration absorption effect, and thus reducing vibration noise. It is understandable that the support devices 3 can also be provided with 3, 5, 6, or 8. In the embodiment of the present application, there is no specific limitation on the number of support devices 3 and the arrangement position on the chassis 21.

[0053] Please refer to Figure 1-3 Specifically, the supporting device 3 includes an elastic member 31 , a connecting member 32 and a hard supporting member 33 .

[0054] One end of the elastic member 31 is connected to the chassis 21. When the appliance body 11 generates vibration during operation, the elastic member 31 can deform to absorb the vibration generated by the appliance body 11, thereby reducing the transmission of vibration from the appliance body 11 to the placement surface, thereby reducing vibration noise. For example, the elastic member 31 can be a spring. In other embodiments, the elastic member 31 can also be an energy-absorbing structural member made of a flexible material, including but not limited to silicone or rubber.

[0055] The connecting member 32 extends along the first direction X, and one end of the connecting member 32 passes through the elastic member 31 and is connected to the chassis 21, so that the deformation direction of the elastic member 31 is limited by the connecting member 32, so that the elastic member 31 can be deformed along the first direction X, so as to reduce the probability of damage to the elastic member 31, so that the elastic member 31 can have a longer service life, ensure that the elastic member 31 can absorb the vibration generated by the electrical body 11, and reduce the vibration transmission from the electrical body 11 to the placement surface, thereby reducing vibration noise. Exemplarily, the connecting member 32 can be a bolt, and the threaded end of the bolt is threadedly connected to the chassis 21, which can improve the convenience of connecting the connecting member 32 to the chassis 21. In other embodiments, the connecting member 32 can also be in other forms. In the embodiment of the present application, the specific form of the connecting member 32 is not limited.

[0056] The hard support member 33 is connected to the other end of the elastic member 31 away from the chassis 21, and the hard support member 33 is placed on the placement surface, so as to support the electrical appliance body 11. The connecting member 32 can move relative to the hard support member 33, so that when the electrical appliance body 11 generates vibration during operation, the elastic member 31 can be deformed, thereby ensuring that the elastic member 31 can absorb the vibration of the electrical appliance body 11 to reduce the vibration noise of the electrical appliance body 11. It can be understood that the hard support member 33 can be at least one of a support seat or a pulley. In the embodiment of the present application, the hard support member 33 can be a damping hard support member, which can reduce the probability of the hard support member 33 being displaced on the placement surface. And because it is a hard support member 33, it is also convenient to move the hard support member 33, so that the household appliance 1 can be moved, so as to facilitate the installation, maintenance and repair of the household appliance 1.

[0057] In the embodiment of the present application, when the appliance body 11 is operating and vibrating, the elastic member 31 is capable of deforming along a first direction X. This deformation includes both compression and tension deformation to absorb the vibration generated by the appliance body 11, thereby reducing the transmission of vibration from the appliance body 11 to the placement surface, and further reducing vibration noise. Furthermore, the connector 32 is used to limit the deformation direction of the elastic member 31, allowing the elastic member 31 to maintain deformation along the first direction X, thereby reducing the probability of damage to the elastic member 31 and extending the service life of the elastic member 31. This ensures that the elastic member 31 can absorb the vibration generated by the appliance body 11, thereby reducing the vibration noise of the household appliance 1 and improving the user experience.

[0058] Please refer to Figure 1-3 In one embodiment, the hard support member 33 has a receiving groove 33A and an avoidance hole 33B connected to the receiving groove 33A. The connecting member 32 is inserted into the avoidance hole 33B, and the end of the connecting member 32 away from the chassis 21 is located in the receiving groove 33A. The end of the connecting member 32 away from the chassis 21 is arranged in the receiving groove 33A, so that when the household appliance 1 vibrates, the chassis 21 can drive the connecting member 32 to move, so that the end of the connecting member 32 away from the chassis 21 can move in the receiving groove 33A. Compared with the connecting member 32 moving outside the hard support member 33, the end of the connecting member 32 away from the chassis 21 moves in the receiving groove 33A, which can reduce the overall volume of the support device 3, thereby reducing the space occupied by the support device 3, and further reducing the overall volume of the household appliance 1, so as to facilitate the production and transportation of the household appliance 1.

[0059] Please refer to Figure 1-3In one embodiment, the rigid support member 33 has a support surface 33C, which is disposed on a side of the rigid support member 33 away from the chassis 21. The support surface 33C is disposed on the placement surface and is used to support the support device 3. Along the first direction X, a first dimension L1 is defined between the end of the connector 32 away from the chassis 21 and the support surface 33C. L1 satisfies the following conditions: 3mm≤L1≤5mm. When the elastic member 31 deforms, the probability of the connector 32 colliding with the placement surface can be reduced, thereby reducing the probability of collision noise generated by the connector 32 colliding with the support surface 33C, thereby improving the user experience. Furthermore, since the space occupied by the connector 32 within the rigid support member 33 can be reduced, the volume of the rigid support member 33 is reduced, the overall volume of the support device 3 is reduced, and the space occupied by the household appliance 1 is reduced, thereby improving the production, manufacturing, and transportation efficiency of the household appliance 1.

[0060] If L1 is less than 3 mm, when the elastic member 31 is deformed, the connecting member 32 is likely to collide with the placement surface, which is likely to generate collision noise, resulting in a louder overall noise in the household appliance 1 and affecting the user experience.

[0061] If L1>5mm, the connecting part 32 will occupy a larger space in the hard support part 33, which will cause the hard support part 33 to be higher, resulting in a larger overall volume of the support device 3, and causing the household appliance 1 to occupy a larger space, affecting the production and transportation efficiency of the household appliance 1.

[0062] Please refer to Figure 1-3 In one embodiment, when the elastic member 31 is deformed along the first direction X, the deformation of the elastic member 31 is greater than or equal to 15% and less than or equal to 30%, which can ensure that the elastic performance of the elastic member 31 is good, thereby improving the vibration reduction effect of the elastic member 31 on the chassis 21, and further improving the vibration reduction effect of the support device 3 on the electrical body 11, thereby reducing the vibration noise of the household appliance 1 and improving the user experience.

[0063] If the deformation of the elastic member 31 is less than 15% when the elastic member 31 is deformed along the first direction X, it indicates that the hardness of the elastic member 31 is relatively large, and the deformation amount that the elastic member 31 can continue to deform is relatively small, resulting in poor elastic performance of the elastic member 31, resulting in a small deformation amount that the elastic member 31 can produce, resulting in poor vibration reduction effect of the elastic member 31 on the chassis 21, resulting in poor vibration reduction effect of the support device 3 on the electrical body 11, and easy generation of vibration noise.

[0064] If the deformation of the elastic member 31 is greater than 30% when the elastic member 31 is deformed along the first direction X, it indicates that the hardness of the elastic member 31 is relatively small. When the deformation of the elastic member 31 is greater than 30%, the deformation that the elastic member 31 can continue to deform is relatively small, resulting in poor elastic performance of the elastic member 31, resulting in a small deformation that the elastic member 31 can produce, resulting in poor vibration reduction effect of the elastic member 31 on the chassis 21, resulting in poor vibration reduction effect of the support device 3 on the electrical body 11, and easy generation of vibration noise.

[0065] Please refer to Figure 1-3 In one embodiment, the elastic member 31 includes an elastic main body portion 311 and a first limiting portion 312. One end of the elastic main body portion 311 is connected to the hard support member 33, and the other end is used to connect to the chassis 21. The first limiting portion 312 is provided on the side of the elastic main body portion 311 facing the hard support member 33. The hard support member 33 includes a supporting main body portion 331 and a second limiting portion 332. The second limiting portion 332 is provided on the side of the supporting main body portion 331 facing the elastic main body portion 311. side, and is connected to the first limiting portion 312; wherein, one of the first limiting portion 312 and the second limiting portion 332 is a protrusion, and the other of the first limiting portion 312 and the second limiting portion 332 is a groove, the protrusion is protruding in the groove, and abuts against the groove wall of the groove. By connecting the first limiting portion 312 and the second limiting portion 332, the contact area between the elastic member 31 and the hard support member 33 can be increased to improve the connection stability between the elastic member 31 and the hard support member 33.

[0066] It can be understood that the elastic part 31 can be molded into one piece with the hard support part 33 through a two-color injection molding process to improve the connection stability between the elastic part 31 and the hard support part 33, and also to improve the assembly efficiency of the elastic part 31 and the hard support part 33, thereby improving the assembly efficiency of the support device 3.

[0067] Please refer to Figure 1-3 In one embodiment, the chassis 21 has a limiting structure 211, and the hard support member 33 cooperates with the limiting structure 211 so that the hard support member 33 drives the chassis 21 to move along a second direction Y, where the second direction Y is perpendicular to the first direction X. When the hard support member 33 is moved along the second direction Y, the hard support member 33 cooperates with the limiting structure 211, enabling the hard support member 33 to drive the chassis 21 to move along the second direction Y, thereby achieving movement of the household appliance 1 and facilitating installation, maintenance, and repair of the household appliance 1. Furthermore, because the hard support member 33 can drive the chassis 21 to move, it can prevent the connector 32 from being subjected to large radial forces, thereby reducing the probability of damage to the connector 32, thereby ensuring that the connector 32 has a longer service life, and thereby ensuring that the base structure 2 has a longer service life.

[0068] Please refer to Figure 1-3 In one embodiment, the limiting structure 211 includes a limiting groove 211A, the elastic member 31 is connected to the bottom of the limiting groove 211A, and at least a portion of the hard support member 33 can extend into the limiting groove 211A, so that when the hard support member 33 is moved along the second direction Y, the hard support member 33 can abut against the groove wall of the limiting groove 211A to drive the chassis 21 to move along the second direction Y, thereby allowing the household appliance 1 as a whole to move along the second direction Y, facilitating the installation, maintenance and repair of the household appliance 1. It is understandable that the limiting structure 211 can also be a limiting column or a limiting bolt, which can be used to abut against the peripheral side of the hard support member 33 by the limiting column or the limiting bolt, so that the hard support member 33 can also drive the chassis 21 to move, so that the household appliance 1 as a whole can move along the second direction Y. In the embodiment of the present application, the specific form of the limiting structure 211 is not limited.

[0069] Please refer to Figure 1-3 In one embodiment, along the first direction X, the length of the rigid support member 33 extending into the limiting groove 211A is a second dimension L2. L2 satisfies the following relationship: 3 mm ≤ L2 ≤ 5 mm, indicating that the deformation of the elastic member 31 is greater than or equal to 15% and less than or equal to 30%. This ensures that the elastic member 31 has good elastic properties, thereby improving the vibration reduction effect of the elastic member 31 on the chassis 21, and thereby improving the vibration reduction effect of the support device 3 on the appliance body 11. Furthermore, L2 satisfies the following relationship: 3 mm ≤ L2 ≤ 5 mm. This reduces the probability of the rigid support member 33 disengaging from the limiting groove 211A when moving along the second direction Y, ensuring that the rigid support member 33 can drive the chassis 21 in the second direction Y, thereby allowing the entire household appliance 1 to move in the second direction Y. This also prevents the connector 32 from being subjected to large radial forces, thereby reducing the probability of damage to the connector 32, thereby extending the service life of the connector 32 and, consequently, the service life of the base structure 2.

[0070] If L2 is less than 3mm, when the hard support member 33 is moved along the second direction Y, there is a probability that the hard support member 33 will easily disengage from the limiting groove 211A, resulting in the hard support member 33 being unable to drive the chassis 21 to move along the second direction Y. In addition, when the hard support member 33 disengages from the limiting groove 211A, the connecting member 32 is subjected to a large radial force, resulting in a high probability of damage to the connecting member 32, affecting the service life of the connecting member 32, and resulting in a shorter service life of the base structure 2. L2 < 3mm can also indicate that the deformation of the elastic member 31 is less than 15%, indicating that the hardness of the elastic member 31 is large, and the deformation that the elastic member 31 can continue to deform is small, resulting in poor elastic performance of the elastic member 31, resulting in a small deformation that the elastic member 31 can produce, resulting in poor vibration reduction effect of the elastic member 31 on the chassis 21, resulting in poor vibration reduction effect of the support device 3 on the electrical main body 11, and easy generation of vibration noise.

[0071] If L2>5mm, it indicates that the deformation of the elastic part 31 is greater than 30%, indicating that the hardness of the elastic part 31 is relatively small. When the deformation of the elastic part 31 is greater than 30%, the deformation that the elastic part 31 can continue to deform is relatively small, resulting in poor elastic performance of the elastic part 31, resulting in a small deformation that the elastic part 31 can produce, resulting in poor vibration reduction effect of the elastic part 31 on the chassis 21, resulting in poor vibration reduction effect of the support device 3 on the electrical body 11, and easy generation of vibration noise.

[0072] Please refer to Figure 1-3 In one embodiment, the hard support member 33 is spaced apart from the groove wall of the limiting groove 211A so that when the household appliance 1 vibrates, the chassis 21 can move relative to the hard support member 33, thereby preventing the vibration of the chassis 21 from being transmitted to the hard support member 33, thereby reducing the probability of the hard support member 33 generating vibration noise.

[0073] Please refer to Figure 1-3 In one embodiment, along the second direction Y, the spacing dimension between the hard support member 33 and the groove wall of the limiting groove 211A is a third dimension L3, where L3 satisfies the following: 0.5mm≤L3≤5mm. This can reduce the probability of collision between the groove wall of the limiting groove 211A and the hard support member 33 when the household appliance 1 vibrates, thereby reducing the probability of collision noise. Furthermore, when the chassis 21 moves relative to the hard support member 33, the cooperation between the limiting groove 211A and the hard support member 33 can be utilized to limit the movement distance of the chassis 21 relative to the hard support member 33, thereby preventing the connector 32 from being subjected to a large radial force, thereby reducing the probability of damage to the connector 32, and thus ensuring that the connector 32 has a longer service life, thereby ensuring that the base structure 2 has a longer service life.

[0074] If L3 is less than 0.5 mm, the distance between the groove wall of the limiting groove 211A and the hard support member 33 is relatively close. When the household appliance 1 vibrates, the groove wall of the limiting groove 211A is likely to collide with the hard support member 33, resulting in a high probability of generating collision noise.

[0075] If L3>5mm, the distance between the groove wall of the limiting groove 211A and the hard support part 33 will be longer. When the household appliance 1 vibrates, the chassis 21 will move a longer distance relative to the hard support part 33, causing the connecting part 32 to bear a larger radial force and a higher probability of damage to the connecting part 32.

[0076] Please refer to Figure 1-3 In one embodiment, the chassis 21 also includes a first positioning portion 212, which is arranged at the bottom of the limiting groove 211A; the elastic member 31 includes an elastic main body portion 311 and a second positioning portion 313, and the elastic main body portion 311 is connected to the chassis 21; the second positioning portion 313 is connected to the elastic main body portion 311 and is matched with the first positioning portion 212; wherein, one of the first positioning portion 212 and the second positioning portion 313 is a protrusion, and the other of the first positioning portion 212 and the second positioning portion 313 is a groove, and the protrusion is protruded in the groove. By using the first positioning and the second positioning portion 313 to match each other, the contact area between the elastic member 31 and the chassis 21 can be increased, thereby improving the connection stability of the elastic member 31 and the chassis 21.
