[0001] The present invention belongs to the technical field of washing machines, and in particular relates to a damping mechanism of a washing machine and the washing machine. Background Art
[0002] The rapid development of technologies related to laundry treatment equipment has brought great convenience to users. Most families need to purchase multiple laundry treatment equipment. At this time, the user's recognition of laundry treatment equipment directly determines the user's purchase target for replacement laundry treatment equipment.
[0003] When a washing machine starts spinning, the inner drum is affected by multiple factors, including motor acceleration, rotational speed, and load eccentricity. This can cause the drum components to collide with the washing machine casing, generating significant vibration and noise, which can even damage the machine. Existing washing machines generally use suspension rods for vibration damping, but these rods have a limited range and are unable to effectively suppress many abnormal startup events, resulting in a poor washing experience for users.
[0004] Chinese patent application number 201110067211.3 discloses a shock-absorbing suspension rod for a washing machine. The invention relates to the field of washing machines, and more specifically, to a shock-absorbing suspension rod for securing the outer tub of a small washing machine. The suspension rod comprises a suspension rod, an upper ball seat, a spring, and a spring seat serially connected to the suspension rod, with a fixing block installed between the upper ball seat and the spring.
[0005] The above-mentioned washing machine still has a hanging rod on the outer drum to maintain the stability of the washing machine. However, due to the small suppression range of the hanging rod itself, it cannot completely suppress the shaking caused by abnormal startup of the washing machine, and the user experience is still poor.

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as limiting the present invention.
[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0037] At present, when the washing machine starts to spin, the washing tub parts often collide with the washing machine body due to the influence of multiple factors such as the acceleration, rotation speed, load eccentricity of the motor drive, etc., causing large vibration and noise, and even damaging the washing machine.
[0038] Example 1
[0039] To solve the above problems, Figures 1 to 4 As shown, this embodiment provides a damping mechanism for a washing machine, comprising:
[0040] Angle support frame 2, arranged at the top of the connection between the two side walls of the box body 1;
[0041] A damping device 3, one end of which is movably connected to the corner support frame 2, and the other end of which is movably connected to the outer wall of the outer barrel 11;
[0042] The damping device 3 is tilted toward the direction close to the outer tub 11 , and the tilting direction of the damping device 3 is consistent with the rotation direction of the inner tub 12 during dehydration.
[0043] In this embodiment, the washing machine includes an inner tub 12 and an outer tub 11. The inner tub 12 is disposed within the outer tub 11 and is used to hold laundry. The washing machine includes a suspension rod 4 disposed on the washing machine housing 1. One end of the suspension rod 4 is fixed to a corner of the top of the housing 1, and the other end is fixed to the outer tub 11 to mitigate vibrations caused by the washing machine during washing or startup.
[0044] In this embodiment, the washing machine also includes a damping mechanism, which is arranged on the outer barrel 11 and is used to suppress the speed of the washing machine's dehydration start-up, prevent the barrel components from colliding with the box body 1, slow down the vibration of the washing machine and reduce noise, thereby improving user experience.
[0045] In a further solution of this embodiment, the damping mechanism includes a corner support frame 2, which is arranged at the connection between the two side walls of the box body 1, that is, the corner support frame 2 is arranged at the corner of the box body 1, providing a position for the installation of the damping device 3 to ensure the stability of the damping device 3.
[0046] Furthermore, the corner support 2 is mounted on the top of the connection between the two side walls of the washing machine 1, that is, the corner support 2 is mounted on the top of the corner of the washing machine 1. One end of the suspension rod 4 is mounted on the corner support 2, and the other end is fixedly connected to the outer tub 11, which is used to maintain the stability of the washing machine during startup or dehydration and to prevent collision between the outer tub 11 and the washing machine 1.
[0047] like Figure 2 As shown, in a further solution of this embodiment, the damping mechanism includes a damping device 3, which is arranged on one side of the suspension rod device 4 and cooperates with the suspension rod device 4 to further suppress the starting speed of the washing machine during dehydration and improve stability.
[0048] Specifically, one end of the damping device 3 is fixed to the bottom of the corner support 2, and the other end is fixed to the outer peripheral side wall of the outer tub 11. The damping device 3 can move between the cabinet 1 and the outer tub 11 to support the cabinet 1 and the outer tub 11, thereby suppressing the startup speed of the washing machine and preventing collision between the cabinet 1 and the outer tub 11.
[0049] Furthermore, the damping device 3 is tilted toward the outer tub 11, that is, the damping device 3 is tilted between the cabinet 1 and the outer tub 11. When the inner tub 12 shakes during the spin start, the damping device 3 can support the shaking of the inner tub 12 and the outer tub 11, thereby suppressing the start-up speed of the spin of the inner tub 12 and maintaining the stability of the spin cycle of the washing machine.
[0050] Furthermore, the inclination direction of the damping device 3 is consistent with the rotation direction of the inner tub 12 during dehydration. Specifically, the inclination direction of the damping device 3 is along the rotation direction of the inner tub 12 during dehydration. When the inner tub 12 starts to dehydrate, the damping device 3 can suppress the speed of the inner tub 12 and prevent the inner tub 12 from shaking, thereby providing a damping effect on the inner tub 12.
[0051] Example 2
[0052] This embodiment is a further description of the above embodiment 1.
[0053] like Figures 2 to 3As shown, in this embodiment, it also includes an upper ball cover 31 and a lower ball cover 32. The upper ball cover 31 is fixedly set at the bottom of the corner support frame 2, and the lower ball cover 32 is set on the outer peripheral side wall of the outer barrel 11. The two ends of the damping device 3 are respectively embedded in the upper ball cover 31 and the lower ball cover 32.
[0054] Specifically, the damping device 3 further includes an upper spherical cover 31, which is disposed at the bottom of the corner support frame 2. The end of the damping device 3 adjacent to the corner support frame 2 is embedded in the corner support frame 2, thereby enabling a movable connection between the damping device 3 and the corner support frame 2. The damping device 3 further includes a lower spherical cover 32, which is fixedly disposed on the outer peripheral side wall of the outer barrel 11. The end of the damping device 3 adjacent to the outer barrel 11 is embedded in the lower spherical cover 32, thereby enabling a movable connection between the damping device 3 and the outer barrel 11.
[0055] Furthermore, the upper and lower spherical covers 31, 32 are spherical in shape, each having a cavity therein. The ends of the damping device 3 are respectively embedded in the cavities of the upper and lower spherical covers 31, 32, thereby movably connecting the damping device 3 with the upper and lower spherical covers 31, 32, thereby suppressing the startup speed of the inner and outer tubs 12, 11 and improving the stability of the washing machine's dehydration process.
[0056] In this embodiment, the damping device 3 is arranged to be tilted downward from one side of the upper spherical cover 31 toward one side of the lower spherical cover 32 , and the horizontal height of the upper spherical cover 31 is higher than the horizontal height of the lower spherical cover 32 .
[0057] Specifically, the damping device 3 is tilted between the box body 1 and the outer barrel 11, and the damping device 3 is tilted downward from one side of the upper ball cover 31 toward one side of the lower ball cover 32, so that the shaking generated when the inner barrel 12 starts can be suppressed by the tilted damping device 3, thereby limiting the shaking of the inner barrel 12 and further suppressing the starting speed of the inner barrel 12.
[0058] Furthermore, the horizontal height of the upper ball cover 31 is higher than the horizontal height of the lower ball cover 32, that is, the damping device 3 is arranged at one end of the corner support frame 2 higher than the other end of the outer barrel 11, thereby forming a structure that is inclined downward from the side of the upper ball cover 31 toward the side of the lower ball cover 32, which is conducive to restricting the inner barrel 12.
[0059] like Figure 3 As shown, in a further solution of this embodiment, a through hole 33 is provided in the middle area of the upper ball cover 31 and the lower ball cover 32, and the two ends of the damping device 3 pass through the through holes 33 on both sides and are slidably connected to the upper ball cover 31 and the lower ball cover 32.
[0060] Specifically, the upper ball cover 31 and the lower ball cover 32 are provided with a through hole 33, and the through hole 33 is opened in the middle area of the upper ball cover 31 and the lower ball cover 32. The two ends of the damping device 3 pass through the through hole 33 respectively and are connected to the upper ball cover 31 and the lower ball cover 32. The damping device 3 can move in the upper ball cover 31 and the lower ball cover 32 to enable the damping device 3 to suppress the shaking of the inner barrel 12 and improve the stability of the dehydration of the washing machine.
[0061] Furthermore, the inner diameter of the through hole 33 is larger than the outer diameter of the damping device 3 .
[0062] Specifically, a through hole 33 is provided in the middle area of the upper ball cover 31 and the lower ball cover 32. The inner diameter of the through hole 33 is larger than the outer diameter of the damping device 3, so that the damping device 3 can slide left and right or front and back through the through hole 33, thereby achieving the effect of suppressing the shaking of the inner barrel 12.
[0063] Example 3
[0064] This embodiment is a further description of the above embodiments 1 and 2.
[0065] like Figure 4 As shown, in this embodiment, the damping device 3 includes a housing 34 and a rod core 35 . The rod core 35 is disposed inside the housing 34 and can slide along the axial direction of the housing 34 .
[0066] Specifically, the damping device 3 includes a shell 34 and a rod core 35. One end of the rod core 35 extends into the shell 34. The rod core 35 can slide along its axial direction in the shell 34 to achieve a damping adjustment effect on the shaking of the inner barrel 12, thereby limiting the dehydration start-up speed of the inner barrel 12.
[0067] In a further solution of this embodiment, one side of the shell 34 is spherical and movably connected to the upper spherical cover 31 ; the other side of the shell 34 extends along the axial direction of the shell 34 to form a channel 36 .
[0068] Specifically, the housing 34 is spherically configured on the side proximal to the corner support 2 and is embedded within the upper spherical cover 31, thereby achieving a movable connection between the housing 34 and the upper spherical cover 31. The housing 34 extends along its axial direction on the side proximal to the outer barrel 11 to form a channel 36, into which the rod core 35 can be inserted.
[0069] Furthermore, a cavity is provided in the spherical structure of the housing 34 , and the cavity is communicated with the channel 36 , so as to facilitate the sliding process of the rod core 35 therein.
[0070] In this embodiment, the end of the rod core 35 away from the housing 34 is spherical and movably connected to the lower spherical cover 32 .
[0071] Specifically, the end of the rod core 35 close to the shell 34 extends into the channel 36 of the shell 34, and the end of the rod core 35 away from the shell 34 is arranged in a spherical structure. The spherical rod core 35 is embedded in the lower ball cover 32 to achieve a movable connection between the rod core 35 and the lower ball cover 32, so that the rod core 35 can move in the lower ball cover 32, thereby suppressing the shaking of the inner barrel 12 and improving the stability of the inner barrel 12 during washing or dehydration.
[0072] like Figure 4 As shown, in a further solution of this embodiment, the damping device 3 further includes a damping ring 37 and a compression spring 38 . The damping ring 37 is embedded on the outer periphery of the top end of the rod core 35 extending into the channel 36 .
[0073] Specifically, the damping device 3 includes a damping ring 37, which is sleeved on the end of the rod core 35 extending into the channel 36. Furthermore, the damping ring 37 is sleeved on the outer periphery of the end of the rod core 35 extending into the channel 36, and the damping ring 37 is movable in the channel 36 to suppress the start-up speed of the dehydration of the inner tub 12.
[0074] In a further solution of this embodiment, the compression spring 38 is arranged below the damping ring 37 and sleeved on the outer peripheral side wall of the end of the rod core 35 extending into the channel 36 .
[0075] Specifically, the damping device 3 also includes a compression spring 38, which is disposed below the damping ring 37 and sleeved around the outer circumference of the end of the rod core 35 that extends into the channel 36. Furthermore, one end of the compression spring 38 is fixedly connected to the bottom of the damping ring 37, and the other end is fixedly connected to the inner wall of the channel 36. When the rod core 35 moves within the channel 36, the compression spring 38 is squeezed and deformed, and the damping ring 37 moves synchronously, suppressing the swaying of the inner tub 12 and limiting the dehydration speed of the inner tub 12. This improves the dehydration stability of the washing machine and enhances the user experience.
[0076] In this embodiment, when the washing machine is not running, the compression spring 38 is not subjected to force, that is, the compression spring 38 does not deform. The damping force of the damping ring 37 can be determined according to the load and operating speed of the washing machine.
[0077] In this embodiment, the movable distance of the rod core 35 in the channel 36 is greater than the maximum downward movement distance of the outer barrel 11 and the inner barrel 12 .
[0078] Specifically, the movement distance of the rod core 35 in the channel 36 in the shell 34 is greater than the maximum downward movement distance of the outer barrel 11 or the inner barrel 12, so that the movement distance of the outer barrel 11 is within the adjustable range of the rod core 35, thereby ensuring that the damping device 3 suppresses the shaking of the outer barrel 11 and the inner barrel 12, and improves the adjustment effect of the damping device 3.
