Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a damping component for reducing the swaying and twisting of a shock absorber and a washing machine. Background Technology

[0002] See Figure 1 As shown, the washing machine tub system 500 is suspended from the washing machine frame 100 by two (or more) suspension springs 600. Several vibration dampers 200 are connected between the bottom of the washing machine tub system 500 and the washing machine frame 100. The vibration dampers 200 are used to provide damping to reduce the vibration of the washing machine tub system 500.

[0003] For washing machines, especially those using dual-stage shock absorbers, the transient vibration of the drum system is relatively large during the low-speed (90rpm~400rpm) spin-drying stage because the dual-stage shock absorber provides almost no damping during one part of its stroke. When the washing machine drum system shakes a lot during the low-speed stage, it will collide with surrounding parts, causing noise, washing machine displacement and other problems.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] Reference Figures 1-11 As shown, this utility model embodiment provides a washing machine including: a washing machine frame 100, a shock absorber 200, and a damping component 300.

[0020] The shock absorber 200 is rotatably connected to the washing machine frame 100; the shock absorber 200 is rotatably connected to the washing machine frame 100 through the mounting bolt column 400. When the washing machine tub 500 is spinning and shaking, the end of the shock absorber 200 will swing and twist back and forth around the mounting bolt column 400.

[0021] The damping assembly 300 includes a damping base 310 and a damping plate 320. The damping base 310 is provided with a first arc surface 311; the first arc surface 311 is provided with a first groove 312 and a second groove 313 arranged in a crisscross pattern; the first groove 312 and the second groove 313 are filled with damping grease. The damping plate 320 has an arc-shaped structure and is elastic; the upper and lower surfaces of the damping plate 320 are the second arc surface 321 and the third arc surface 322, respectively; the damping plate 320 is connected to the damping base 310, and the third arc surface 322 is matched with the first arc surface 311; multiple micropores are distributed on the damping plate 320.

[0022] The damping assembly 300 is installed between the washing machine frame 100 and the shock absorber 200, and the arc end face 210 of the shock absorber 200 mates with the second arc surface 321. The first arc surface 311 needs to match the sweep trajectory of the swing at the end of the shock absorber 200.

[0023] Specifically, due to the first groove 312 and the second groove 313 and the damping grease filled in the first groove 312 and the second groove 313, a negative pressure is formed between the third arc surface 322 and the first arc surface 311, which helps the damping sheet 320 to be tightly adhered to the first arc surface 311, so that the third arc surface 322 and the first arc surface 311 remain in contact. Since the arc end face 210 of the shock absorber 200 mates with the second arc surface 321, when the arc end face 210 contacts the second arc surface 321 at a certain position, the arc end face 210 will radially compress the damping plate 320 at that position. In addition, the damping grease in the first groove 312 and the second groove 313 exhibits capillary action. Therefore, under the combined effect of the arc end face 210 compressing the damping plate 320 and the capillary action of the damping grease, the damping grease will overflow from the micropores to the mating surface between the arc end face 210 and the second arc surface 321, increasing the damping of the shock absorber 200. Therefore, when the washing machine vibrates during the spin-drying process, the vibration damper 200 will make a swaying and twisting reciprocating motion. This application adds a damping component 300 to the end of the vibration damper 200. The end of the vibration damper 200 and the damping plate 320 of the damping component 300 rub against each other to consume energy, which can generate damping that resists the twisting of the vibration damper 200, thereby reducing the vibration of the washing machine drum system 500 and extending its service life.

[0024] When the arc end face 210 contacts the second arc surface 321 at a certain position and squeezes the damping plate 320 at that position, the damping plate 320 deforms and falls into the first groove 312, thereby preventing the damping plate 320 from moving around in the circumferential direction and improving the stability of the damping assembly 300.

[0025] This design installs a damping structure between the vibration damper 200 and the washing machine frame 100. During the swaying and torsional movement of the vibration damper 200, the end of the vibration damper 200 rubs against the damping plate 320 in the damping assembly 300, increasing the swaying and torsional resistance of the vibration damper 200 and providing a certain degree of damping. Under the same load excitation of the washing machine tub system 500, the amplitude of the swaying and torsional movement of the vibration damper 200 around the mounting bolt column 400 is reduced, indirectly reducing the vibration of the washing machine tub system 500.

[0026] Furthermore, along the circumference of the first arc surface 311, the damping base 310 has mounting grooves 314 at both ends; the damping plate 320 has snap-fit ​​parts 323 at both ends; the snap-fit ​​parts 323 are inserted into the mounting grooves 314.

[0027] Specifically, in this embodiment, the damping base 310 and the damping plate 320 are connected and fixed by the cooperation of the snap-fit ​​part 323 and the mounting groove 314, which makes installation convenient.

[0028] Furthermore, the upper surface of the damping base 310 is recessed downward to form a groove body 315; the first arc surface 311 is provided on the bottom wall of the groove body 315; and the mounting groove 314 is provided at both ends of the groove body 315.

[0029] Specifically, in this embodiment, the mating surfaces of the damping base 310 and the damping plate 320 are set in the groove body 315. In this way, the side of the groove body 315 can axially limit the damping plate 320 and prevent the damping plate 320 from detaching from the damping base 310.

[0030] Furthermore, the angle α between the end face of the first groove 312 and the first arc surface 311 is an obtuse angle. In some embodiments, the angle α is 100°~120°.

[0031] Specifically, this embodiment can confine the damping grease within the first groove 312, preventing the damping grease from overflowing from the end of the first groove 312 onto the surface of the damping base 310, while also facilitating production.

[0032] Furthermore, both the first groove 312 and the second groove 313 are arc-shaped. The first groove 312 extends circumferentially on the first arc surface 311, and the second groove 313 extends axially on the first arc surface 311. The first groove 312 and the second groove 313 have the same depth; the depth of the first groove 312 is 0.3mm to 0.8mm.

[0033] Furthermore, the damping sheet 320 is made of polyurethane.

[0034] Specifically, this embodiment is more effective at reducing vibration and noise.

[0035] Furthermore, this application also includes a vibration isolation section disposed between the washing machine frame 100 and the damping base 310. In some embodiments, the vibration isolation section may be a vibration isolation pad.

[0036] Specifically, in this embodiment, a vibration isolation part is provided between the washing machine frame 100 and the damping component 300, which plays a role in shock absorption and noise reduction, and can achieve better vibration isolation performance.

[0037] Furthermore, the damping assembly 300 is detachably connected to the washing machine frame 100. In some embodiments, the damping assembly 300 is bolted to the washing machine frame 100. In other embodiments, the damping assembly 300 is snap-fitted to the washing machine frame 100.

[0038] Specifically, this embodiment adopts a detachable connection method, which facilitates the disassembly, replacement and maintenance of the damping component 300.

[0039] This application adds a damping component 300 to the end of the shock absorber 200. When the shock absorber 200 swings and twists, the end of the shock absorber 200 rubs against the damping plate 320 in the damping component 300 to consume energy, thereby generating damping that hinders the swinging and twisting of the shock absorber 200, reducing the shaking of the washing machine tub system 500, improving the vibration of the washing machine, and solving problems such as noise and displacement caused by shaking and impact of the washing machine tub system 500 during the low-speed spin-drying stage.

[0040] This application can effectively increase the resistance to the swaying and twisting of the vibration damper 200 and provide a certain amount of damping, thereby suppressing the vibration of the washing machine drum system 500 during the low-speed dehydration stage.

[0041] It should be noted that damping plates of different sizes (thickness / width) 320 can provide different damping forces.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
