Description

Technical Field

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

[0002] Household washing machines are essential appliances, but they generate significant vibrations during operation, which can severely impact the user experience. Most washing machines are equipped with shock absorbers, which can offset most of the vibrations, but not completely. Small-amplitude, high-frequency vibrations still act on the machine casing. The support structure of a conventional washing machine is usually fixedly connected to the casing, allowing these vibrations to be further transmitted to the support structure. This causes frequent collisions between the support structure and the ground, still resulting in a noticeable noise impact. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a washing machine cabinet support component to solve the problem of noise caused by frequent collisions between the corners of the washing machine cabinet and the ground due to vibration.

[0004] Technical solution: To achieve the above objectives, the present invention provides a washing machine cabinet support assembly, including a connecting plate, wherein the connecting plate is attached to and fixedly connected to the inclined mounting surface of the bottom corner of the washing machine cabinet;

[0005] The connecting plate has a raised structure formed in the middle area away from the box body, and the raised structure is provided with an assembly hole, the axis of which is perpendicular to the inclined mounting surface.

[0006] A support rod is inserted into the assembly hole, and the support rod slides in the assembly hole. A support accessory is fixedly connected to the bottom end of the support rod, and an elastic element is fixedly connected to the top end of the support rod. The elastic element fits against the inclined mounting surface.

[0007] Furthermore, a cavity is formed between the protruding structure and the inclined mounting surface. A limiting surface is provided in the cavity, and the limiting surface is parallel to the inclined mounting surface. A limiting plate is provided at the top of the support rod. The elastic element is connected to the upper side of the limiting plate. When the limiting plate is in contact with the limiting surface, the limiting plate and the inclined mounting surface clamp and compress the elastic element.

[0008] Furthermore, the protruding structure includes a first-order boss and a second-order convex hull. The outline shape of the first-order boss is consistent with the outline shape of the connecting plate. The second-order convex hull is disposed in the middle of the first-order boss, and the assembly hole is provided on the second-order convex hull.

[0009] Furthermore, the second-order convex hull is a circular arc convex hull structure.

[0010] Furthermore, the edge of the connecting plate is provided with a positioning lug, which fits against the wall of the washing machine. The positioning lug is provided with a limiting hole, and the positioning bolt passes through the limiting hole and is screwed into the positioning screw hole on the wall of the washing machine.

[0011] Furthermore, an elastic washer is fixedly sleeved at the bottom end of the support rod.

[0012] Beneficial effects: The washing machine cabinet support component of this utility model is fixedly connected to the cabinet by a stamped metal sheet, and the support structure is elastically connected to the cabinet and the metal sheet. This achieves absorption and cancellation of vibration transmitted from the cabinet to the support structure. At the same time, the supporting force and limiting force of the metal sheet on the support structure enhance the support strength of the support component, thereby ensuring the stability of the washing machine support and achieving the effect of noise reduction. Attached Figure Description

[0013] Figure 1 This is a schematic cross-sectional view of one embodiment of the present invention;

[0014] Figure 2 This is a schematic diagram of the connecting plate and protrusion structure according to an embodiment of the present invention. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figure 1-2 The washing machine cabinet support assembly includes a connecting plate 1, which is attached to and fixedly connected to the inclined mounting surface 10 at the bottom corner of the washing machine cabinet. The inclined mounting surface 10 is a beveled surface of a right-angled corner, which has a triangular profile structure. Its three edges are the intersection lines with the three adjacent cabinet walls of the washing machine. Each of the four corners of the bottom of the washing machine is provided with an inclined mounting surface, and a support assembly is installed on each inclined mounting surface. The cabinet is supported by the four support assemblies.

[0017] The connecting plate 1 has a raised structure 2 formed in the middle area away from the box body. The raised structure 2 is provided with an assembly hole 3. The axis of the assembly hole 3 is perpendicular to the inclined mounting surface 10. A support rod 4 is inserted into the assembly hole 3. The support rod 4 is slidably engaged with the assembly hole 3. A support accessory 5 is fixedly connected to the bottom end of the support rod 4. An elastic element 6 is fixedly connected to the top end of the support rod 4. The elastic element 6 is in contact with the inclined mounting surface 10.

[0018] The supporting accessories can be functional components such as telescopic support feet or wheels to enable functions such as chassis height adjustment or washing machine movement. The supporting accessories are connected to elastic elements via support rods to form an elastic support structure. The elastic elements then contact the inclined mounting surface on the bottom side of the casing, achieving the effect of supporting the four corners of the washing machine from four upward inclined directions through four elastic support structures. When the washing machine vibrates during operation, the compression and release of the elastic elements counteracts the transmission of vibration from the casing to the support structure, thereby preventing frequent lifting and falling of the washing machine corners and thus avoiding noise generation. The connecting plate is used to fix the mounting hole relative to the inclined mounting surface 10. The mounting hole constrains the relative position and relative movement of the support rod and the corresponding inclined mounting surface, minimizing the relative movement amplitude between the casing and the support structure. Preferably, an elastic sleeve is fitted between the mounting hole and the support rod. The presence of the elastic element and the elastic sleeve provides the casing with a certain amount of movement space, and the generated elastic restoring force conversely restricts the movement amplitude of the casing, fundamentally achieving noise reduction through vibration damping.

[0019] Preferably, the support components on the four corners of the machine are symmetrically arranged about the left and right sides of the machine body. For washing machines with vertical drums, the structure of the support components on the four corners can be completely identical, and they can be arranged symmetrically about the front and back, left and right sides or center of the machine body.

[0020] A cavity 7 is formed between the protruding structure 2 and the inclined mounting surface 10. A limiting surface 71 is provided within the cavity 7, and the limiting surface 71 is parallel to the inclined mounting surface 10. A limiting plate 41 is provided at the top of the support rod 4. The upper side of the limiting plate 41 is connected to the elastic member 6. When the limiting plate 41 is in contact with the limiting surface 71, the limiting plate 41 and the inclined mounting surface 10 clamp and compress the elastic member 6. The elastic member 6 is composed of multiple springs or rubber pads, while the connecting plate and the protruding structure are integral sheet metal parts. The protruding structure is formed by stamping pre-cut metal material, and its concave surface is fitted to the inclined mounting surface of the chassis, thereby forming a cavity on the inner side.

[0021] In the non-operating state, when only the weight of the machine body is applied, the elastic force generated by the slight compression of the elastic element presses the limiting plate against the limiting surface, ensuring the machine body is balanced. When clothes are loaded into the inner drum, the center of gravity of the machine body lowers, further compressing the elastic element and causing the limiting plates at the four corners to move away from the limiting surface, creating a gap. At this time, the metal connecting plate with the raised structure is a relatively fixed unit with the machine body, and the support rod and its corresponding support accessories are also relatively fixed units, connected by elastic structural supports or pads. When the washing machine starts operating, the internal shock absorbers absorb a large amount of vibration, and a small amount of vibration is transmitted to the machine body, causing slight vibrations. These vibrations are transmitted to the support rod through the elastic element and elastic pads, where they are absorbed and canceled out by the elastic force. This prevents the support rod from being affected by vibration, thus preventing relative movement between the four support structures in contact with the ground and avoiding noise generation. Preferably, an elastic washer 8 is fixedly sleeved at the bottom end of the support rod 4. The elastic washer 8 and the elastic sleeve are integrally set. When the weight of the clothing is large, the relative displacement between the support rod and the mounting hole is large, so that the port of the mounting hole directly presses on the elastic washer 8, thereby enhancing the elastic force, improving the shock absorption effect, and increasing the pressure-bearing area, thus improving the pressure-bearing capacity.

[0022] The protruding structure 2 includes a first-order boss 21 and a second-order convex hull 22. The outline shape of the first-order boss 21 is consistent with the outline shape of the connecting plate 1. The second-order convex hull 22 is disposed in the middle of the first-order boss 21, and the mounting hole 3 is provided on the second-order convex hull 22. The second-order convex hull 22 is a circular arc-shaped convex hull structure. The double-order protruding structure is beneficial to enhance the support strength. The circular arc-shaped convex hull structure has a strong load-bearing capacity. The position of the mounting hole is set off-center to the downward side relative to the center of the circular convex hull, thereby enhancing the limiting support effect of the metal parts on the support rod and improving the support strength and stability of the support structure.

[0023] The connecting plate 1 has positioning lugs 11 on its edge, which fit snugly against the washing machine casing wall. Each positioning lug 11 has a limiting hole 12, through which a positioning bolt passes and engages with a positioning screw hole on the casing wall. During installation, first, simultaneously lift the positioning lugs and connecting plate against the corresponding casing wall surfaces, aligning the limiting hole 12 with the positioning screw hole on the casing wall. Then, install the positioning bolts, ensuring the positioning lugs are securely fitted against the corresponding casing wall. Finally, tighten each of the fastening screws on the connecting plate. The positioning lugs ensure accurate positioning of the support assembly relative to the machine body, guaranteeing the aforementioned desired effect after installation.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
