Description

Technical Field

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

[0002] Traditional washing machine drums are connected to the cabinet 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 drum to the cabinet, while also reducing and attenuating the amplitude of drum vibrations. These components are core parts of the washing machine.

[0003] However, traditional support systems have the following problems:

[0004] Existing technologies support structural noise caused by the relative motion of multiple structures with various motion amplitudes in the support system, and cannot provide sufficient damping force while avoiding the impact of excessive stiffness on the system's dynamic performance. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the structural noise caused by various relative movements of multiple structures in the existing support system, and the shortcomings of not being able to provide sufficient damping force while avoiding the influence of excessive stiffness on the dynamic performance of the system. The present invention provides a support device and a washing machine containing the device.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A support device for supporting the drum of a washing machine within the casing of the washing machine, the support device comprising:

[0008] The first support, the first end of the first support is used to connect the cylinder;

[0009] The second bracket has its first end connected to the housing.

[0010] An elastic support assembly, wherein a first end of the elastic support assembly is connected to a second end of a first bracket, and a second end of the elastic support assembly is connected to a second end of a second bracket, the elastic support assembly includes a vibration isolation support part made of elastic material, the vibration isolation support part extends from the first bracket to the second bracket and has multiple bends;

[0011] The deformation of the elastic support component is configured to change as the weight of the cylinder decreases or increases.

[0012] In this design, the elastic support assembly includes a vibration isolation support section made of elastic material. This arrangement helps to reduce the vibration transmitted from the cylinder to the box and provides flexible buffering for the cylinder's vibration. The vibration isolation support section extends from the first support to the second support and has multiple bends. These bends increase the total length of the elastic material in the vibration isolation support section, allowing the elastic material to have a relatively large strain when the overall elastic support assembly undergoes small deformation, thereby generating more energy loss and providing greater resistance. Compared to the overall block structure, the vibration isolation support section has a very small load-bearing and deformation resistance capacity, i.e., it has low stiffness.

[0013] In addition, the individual support device provides system damping force through the elastic material in the process of elastic support components, avoiding structural noise caused by various relative movements of multiple structures.

[0014] Preferably, the elastic support assembly further includes a first vibration isolation mounting part and a second vibration isolation mounting part, wherein the first vibration isolation mounting part is used to connect the cylinder and the second vibration isolation mounting part is used to connect the box body;

[0015] The first vibration isolation mounting part, the vibration isolation support part, and the second vibration isolation mounting part are connected in sequence, and the first vibration isolation mounting part and the second vibration isolation mounting part are made of elastic material.

[0016] In this solution, the first vibration isolation mounting part and the second vibration isolation support part further improve the vibration isolation effect of the support device. In addition, the first vibration isolation mounting part and the second vibration isolation mounting part also increase the installation area of ​​the support device, the cylinder and the box, making the installation more stable.

[0017] Preferably, the elastic support assembly includes multiple vibration isolation support parts, which are spaced apart between the first vibration isolation mounting part and the second vibration isolation mounting part.

[0018] In this design, the addition of multiple vibration isolation supports further enhances the ability of the support device to provide resistance.

[0019] Preferably, the degree of curvature of the portion of the vibration isolation support closer to the cylinder is less than the degree of curvature of the portion of the vibration isolation support closer to the box.

[0020] In this scheme, the above-mentioned arrangement results in increasing resistance as the cylinder becomes heavier. This is because the total length of the curved section near the box in the vibration isolation support is longer, and the greater the gravity it experiences, the greater the degree and area of ​​deformation of the curved section, thus providing greater resistance. Moreover, since the deformation area of ​​the vibration isolation support is relatively large, the degree of deformation can be relatively small, thereby relatively reducing the stiffness of the vibration isolation support after deformation and improving the vibration isolation effect.

[0021] Preferably, the vibration isolation support includes a first curved portion and a second curved portion, wherein a first end of the first curved portion is connected to the first vibration isolation mounting portion and a second end extends toward the second vibration isolation mounting portion, and a first end of the second curved portion is connected to the second vibration isolation mounting portion and a second end extends toward the first vibration isolation mounting portion.

[0022] The vibration isolation support also includes an intermediate connecting part, the two ends of which are respectively connected to the second end of the first curved part and the second end of the second curved part, and the intermediate connecting part has multiple curved portions;

[0023] In the horizontal direction, the intermediate connecting portion, excluding the two ends, is spaced apart from the first curved portion and the second curved portion.

[0024] In this scheme, the above-mentioned arrangement allows the vibration isolation support to have more bends and curved sections within a limited space, resulting in a longer total length of the vibration isolation support.

[0025] Preferably, the cylinder includes a cylinder body and a first mounting portion, a first end of the first mounting portion is connected to the cylinder body, a second end of the first mounting portion faces the first bracket and has a first step portion, and the end of the first bracket facing the first mounting portion has a first vibration isolation step portion that can be adapted to be installed with the first step portion.

[0026] The end face of the first bracket away from the first mounting part is configured to be fitted and installed to match the end face of the first vibration isolation support part facing the first bracket.

[0027] In this design, the first and second steps allow the cylinder and the first support to be installed through two stepped surfaces, resulting in a large installation area and relatively stable installation.

[0028] In addition, the end face of the first bracket away from the first mounting part is configured to be adapted to the end face of the first vibration isolation support part facing the first bracket, so that the first bracket is stably connected to the elastic support assembly.

[0029] Preferably, the second support includes a first plate and a second plate, the first plate and the second plate are connected and form an "L" shape, the box includes a crossbeam, the two ends of the crossbeam are used to connect to the box, the first plate is installed on the crossbeam and extends into the box along the height direction of the box, and the second plate extends into the box along the width direction of the box.

[0030] The end face of the second plate facing the second vibration isolation mounting part is configured to be adapted to the end face of the second vibration isolation mounting part facing the second plate.

[0031] In this design, the first plate is mounted on the crossbeam and extends into the box along the height direction, while the second plate extends into the box along the width direction. This arrangement allows the second bracket to be close to the cylinder, facilitating the installation of the cylinder on the box.

[0032] Furthermore, the end face of the second plate facing the second vibration isolation mounting part is configured to be adapted to the end face of the second vibration isolation mounting part facing the second plate; the above configuration enables the second bracket to be stably connected to the elastic support assembly.

[0033] Preferably, the elastic support component is a one-piece molded structure.

[0034] In this solution, the aforementioned one-piece molding design saves space occupied by the suspension device; in addition, the one-piece molding component is generally not easily damaged or broken into several parts when subjected to gravity.

[0035] This utility model also provides a washing machine, which includes a cabinet, a drum and the aforementioned support device, wherein the drum is supported in the cabinet by multiple support devices.

[0036] Preferably, the washing machine also includes multiple suspension springs for suspending the drum from the cabinet.

[0037] In this design, the aforementioned suspension springs can reduce the vibration transmitted from the cylinder to the housing.

[0038] The positive and progressive effects of this utility model are as follows: The elastic support assembly includes a vibration isolation support part made of elastic material. This arrangement is beneficial for reducing the vibration transmitted from the cylinder to the box body and for providing flexible buffering of the cylinder's vibration. The vibration isolation support part extends from the first support to the second support and has multiple bends. These bends increase the total length of the elastic material in the vibration isolation support part, allowing the elastic material to have a relatively large strain when the overall elastic support assembly undergoes small deformation, thereby generating more energy loss and providing greater resistance. However, compared to the overall block structure, the vibration isolation support part has a very small load-bearing and deformation resistance capacity, i.e., it has low stiffness. In addition, the individual support device provides system damping force through the elastic material in the process of elastic support assembly, avoiding structural noise caused by various relative movements of multiple structures.

[0066] 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.

[0067] like Figure 1-5As shown, this embodiment provides a support device 100 for supporting the drum 400 of a washing machine 200 on the housing 300 of the washing machine 200. The support device 100 includes: a first bracket 1, the first end of which is connected to the drum 400; a second bracket 2, the first end of which is connected to the housing 300; and an elastic support assembly 3, the first end of which is connected to the second end of the first bracket 1, and the second end of which is connected to the second end of the second bracket 2. The elastic support assembly 3 includes a vibration-damping support portion 31 made of elastic material, which extends from the first bracket 1 to the second bracket 2 and has multiple bends. The deformation of the elastic support assembly 3 is configured to change with the decrease or increase of the weight of the drum 400.

[0068] In this embodiment, the elastic support assembly 3 includes a vibration isolation support portion 31 made of elastic material. This arrangement is beneficial for reducing the vibration transmitted from the cylinder 400 to the box 300 and for providing flexible buffering of the vibration of the cylinder 400. The vibration isolation support portion 31 extends from the first bracket 1 to the second bracket 2 and has multiple bends. The bends increase the total length of the elastic material of the vibration isolation support portion 31, so that the elastic material of the elastic support assembly 3 has a relatively large strain when the overall deformation is small, thereby generating more energy loss, that is, providing greater resistance. However, the vibration isolation support portion 31 has a very small load-bearing and deformation resistance capacity compared to the overall block structure, that is, it has a small stiffness.

[0069] In addition, the individual support device 100 provides system damping force through the elastic material in the process of elastic support component 3, avoiding structural noise caused by various relative movements of multiple structures.

[0070] It should be noted that the rubber material or other polymer damping material used in this embodiment is mainly used to provide damping force and can replace conventional dampers (vibration dampers). The stiffness of the entire suspension system of the washing machine 200 is still provided by conventional suspension springs 500.

[0071] like Figure 2-5 As shown, the elastic support assembly 3 also includes a first vibration isolation mounting part 32 and a second vibration isolation mounting part 33. The first vibration isolation mounting part 32 is used to connect the cylinder 400, and the second vibration isolation mounting part 33 is used to connect the box 300. The first vibration isolation mounting part 32, the vibration isolation support part 31, and the second vibration isolation mounting part 33 are connected in sequence. The first vibration isolation mounting part 32 and the second vibration isolation mounting part 33 are made of elastic material.

[0072] In this embodiment, the provision of the first vibration isolation mounting part 32 and the second vibration isolation support part 31 further improves the vibration isolation effect of the support device 100. In addition, the first vibration isolation mounting part 32 and the second vibration isolation mounting part 33 also increase the installation area of ​​the support device 100, the cylinder 400 and the box 300, making the installation more stable.

[0073] It should be noted that, in the absence of the first vibration isolation mounting part 32 and the second vibration isolation mounting part 33, the support device 100 can be mounted on the cylinder 400 and the box 300 through both ends of the vibration isolation support part 31.

[0074] like Figure 4 As shown, the elastic support assembly 3 includes a plurality of vibration isolation support parts 31, which are spaced apart between the first vibration isolation mounting part 32 and the second vibration isolation mounting part 33.

[0075] In this embodiment, the provision of multiple vibration isolation supports 31 further enhances the ability of the support device 100 to provide resistance.

[0076] like Figure 5 As shown, the degree of bending of the portion of the vibration isolation support 31 near the cylinder 400 is less than the degree of bending of the portion of the vibration isolation support 31 near the box 300.

[0077] In this embodiment, the above-mentioned arrangement results in increasing resistance as the cylinder 400 becomes heavier. This is because the total length of the curved portion of the vibration isolation support 31 near the box 300 is longer, resulting in greater gravity and a larger degree and area of ​​deformation of the curved portion, thus providing greater resistance. Furthermore, since the deformation area of ​​the vibration isolation support 31 is relatively large, the degree of deformation can be relatively small, thereby relatively reducing the stiffness of the vibration isolation support 31 after deformation and improving the vibration isolation effect.

[0078] It should be noted that the aforementioned weight change of the drum 400 is due to the fact that when the washing machine 200 is in the spin-drying state, most of the water in the drum 400 is drained, making the overall weight of the drum 400 lighter. When the suspension device is in the second position, the washing machine 200 is in the washing state, and at this time, the water in the drum 400 has not yet been drained, making the overall weight of the drum 400 heavier. Furthermore, the stiffness of the support device 100 varies depending on the degree of deformation; the greater the degree of deformation, the greater the stiffness of the support device 100, and vice versa.

[0079] like Figure 4 and Figure 5As shown, the vibration isolation support 31 includes a first curved portion 34 and a second curved portion 35. The first end of the first curved portion 34 is connected to the first vibration isolation mounting portion 32, and the second end extends toward the second vibration isolation mounting portion 33. The first end of the second curved portion 35 is connected to the second vibration isolation mounting portion 33, and the second end extends toward the first vibration isolation mounting portion 32. The vibration isolation support 31 also includes an intermediate connecting portion 36. The two ends of the intermediate connecting portion 36 are respectively connected to the second ends of the first curved portion 34 and the second curved portion 35. The intermediate connecting portion 36 has multiple curved sections. In the horizontal direction, the portions of the intermediate connecting portion 36 other than the two ends are spaced apart from the first curved portion 34 and the second curved portion 35.

[0080] As an example, the structure consisting of the first curved portion 34, the intermediate connecting portion 36, and the second curved portion 35, when viewed from the side, is basically in the shape of an "8".

[0081] In this embodiment, the above-mentioned arrangement makes the vibration isolation support 31 have more bends and bends within a limited space, resulting in a longer total length of the vibration isolation support 31.

[0082] like Figure 2 As shown, the cylinder 400 includes a cylinder body 410 and a first mounting portion 420. The first end of the first mounting portion 420 is connected to the cylinder body 410. The second end of the first mounting portion 420 faces the first bracket 1 and has a first step portion 430. The end of the first bracket 1 facing the first mounting portion 420 has a first vibration isolation step portion 11 that can be adapted to be installed with the first step portion 430. The end face of the first bracket 1 away from the first mounting portion 420 is configured to be adapted to be installed with the end face of the first vibration isolation support portion 31 facing the first bracket 1.

[0083] In this embodiment, the arrangement of the first step portion 430 and the second step portion allows the cylinder 400 and the first bracket 1 to be installed through two stepped surfaces, resulting in a large installation area and relatively stable installation.

[0084] Furthermore, the end face of the first bracket 1 away from the first mounting portion 420 is configured to be adapted to the end face of the first vibration isolation support portion 31 facing the first bracket 1, so that the first bracket 1 is stably connected to the elastic support assembly 3.

[0085] It should be noted that the connection between the vibration isolation support 31 and the first vibration isolation mounting part 32 and the second vibration isolation mounting part 33 can be by bonding or bolting. The connection between the first bracket 1 and the cylinder 400, and the connection between the second bracket 2 and the box 300 can also be by bonding or bolting.

[0086] In addition, the end face of the first bracket 1 away from the first mounting part 420 and the end face of the first vibration isolation support part 31 facing the first bracket 1 are both flat plate surfaces, which can be fitted together for installation.

[0087] The step surface of the first step 430 faces the inside of the housing 300, and the step surface of the second step faces the outside of the housing 300. This arrangement makes the adapter installation point closer to the inside of the housing 300, and less susceptible to damage from the external environment.

[0088] like Figure 2 As shown, the second bracket 2 includes a first plate 21 and a second plate 22. The first plate 21 and the second plate 22 are connected and form an "L" shape. The box 300 includes a crossbeam 310. The two ends of the crossbeam 310 are used to connect to the box 300. The first plate 21 is installed on the crossbeam 310 and extends into the box 300 along the height direction of the box 300. The second plate 22 extends into the box 300 along the width direction of the box 300. The end face of the second plate 22 facing the second vibration isolation mounting part 33 is configured to be adapted to the end face of the second vibration isolation mounting part 33 facing the second plate 22.

[0089] In this embodiment, the first plate 21 is mounted on the crossbeam 310 and extends into the box 300 along the height direction of the box 300, and the second plate 22 extends into the box 300 along the width direction of the box 300. The above arrangement makes the second bracket 2 close to the cylinder 400, which facilitates the installation of the cylinder 400 on the box 300.

[0090] Furthermore, the end face of the second plate 22 facing the second vibration isolation mounting part 33 is configured to be adapted to the end face of the second vibration isolation mounting part 33 facing the second plate 22; the above arrangement enables the second bracket 2 to be stably connected to the elastic support assembly 3.

[0091] It should be noted that the end face of the second plate 22 facing the second vibration isolation mounting part 33 and the end face of the second vibration isolation mounting part 33 facing the second plate 22 are both flat plate surfaces, and the two can be fitted together for installation.

[0092] like Figure 4 As shown, the elastic support component 3 is a one-piece molded structure.

[0093] In this embodiment, the one-piece design saves space occupied by the suspension device; in addition, the one-piece component is generally not easily damaged or broken into several parts when subjected to gravity.

[0094] like Figure 1 As shown, the present invention also provides a washing machine 200, which includes a cabinet 300, a drum 400 and the aforementioned support device 100. The drum 400 is supported in the cabinet 300 by a plurality of support devices 100.

[0095] Preferably, the washing machine 200 also includes a plurality of suspension springs 500 for suspending the drum 400 from the cabinet 300.

[0096] In this embodiment, the suspension spring 500 can reduce the vibration transmitted from the cylinder 400 to the housing 300.

[0097] It should be noted that the aforementioned suspension spring 500 can also replace the support device 100 or other vibration-isolation components in this application.

[0098] The washing machine 200 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the washing machine 200 to perform corresponding operations, thereby realizing intelligent control of the washing machine 200 and improving the user experience.
