With the development of the washing machine industry and the improvement of people's living standards, drum washing machines have occupied an increasingly large proportion of the washing machine market.

[0003] The traditional shock absorber structure is directly installed on both sides of the outer barrel and then fixed with a pin. The head is made of TPE rubber for buffering. The principle of shock absorption is that the polyurethane sponge in the plastic sleeve and the steel sleeve generate damping force to achieve the effect of shock absorption.

[0004] When the washing machine rotates at a low speed and the clothes are too eccentrically heavy, the outer barrel and the hanging spring will vibrate, and even produce a "bang bang" sound.

However, no matter whether the outer barrel vibrates left and right or up and down, the direction of the damping force provided by the shock absorber is fixed, that is, the horizontal and vertical components of the damping force are fixed, and cannot be adjusted according to the actual vibration state of the outer barrel, which leads to poor shock absorption effect.

[0040] See also Figure 6The mounting plate 1 comprises a plate body 101, a first rotating seat 102 and a second rotating seat 103, both of which are composed of a U-shaped seat and a rotating shaft, the first rotating seat 102 is fixed to the upper surface of the plate body 101 away from the outer barrel end, and the center of the arc-shaped inner wall of the adjusting slide 51 is located on the axis of the first rotating seat 102, the bottom end of the fixed part of the shock absorber 2 is fixed to the rotating shaft of the first rotating seat 102, the second rotating seat 103 is fixed to the upper surface of the plate body 101 close to the outer barrel end, the bottom end of the fixed part of the electric push rod 6 is fixed to the rotating shaft of the second rotating seat 103, the four corners of the plate body 101 are provided with mounting holes 104, and the lower surface of the plate body 101 is provided with a shock-absorbing pad 105.

[0041] See also Figure 7 As shown, the present application provides a drum washing machine, including a box body 9, the outer barrel 10 is arranged in the box body 9, the mounting plate 1 of the shock absorber assembly is fixed to the inner wall of the bottom end of the box body 9, the outer barrel connecting seat 5 of the shock absorber assembly is fixed to the outer wall of the outer barrel 10, and the vibration monitor 11 is arranged on the inner wall of the box body 9. The vibration monitor 11 is used to monitor the vibration degree and vibration direction of the outer barrel 10. A plurality of vibration monitors 11 can be provided. The vibration monitor 11 transmits the detected vibration degree and vibration direction of the outer barrel 10 to a microprocessor. The microprocessor controls the extension and retraction of the electric push rod 6 through a controller according to the vibration degree and vibration direction of the outer barrel 10, thereby driving the shock absorber 2 to rotate, adjusting the direction of the damping force applied by the shock absorber 2 to the outer barrel 10, and improving the shock absorption effect by restraining the vibration direction of the outer barrel.

[0042] When the washing machine is running at a low speed and the outer drum vibrates due to the eccentricity of the clothes, there are three vibration states:

[0043] 1. The outer barrel 10 is tilted and vibrated, that is, the up-and-down vibration amplitude and the left-and-right vibration amplitude of the outer barrel are similar.

[0044] See also Figure 8 and Fig. 9 As shown, at this time, the electric push rod 6 rotates with the shock absorber 2 until the shock absorber 2 forms an angle of 45° with the horizontal direction. The damping force applied by the shock absorber 2 to the outer barrel is F1, the horizontal component of the damping force F1 is F1X, and the vertical component is F1Y. F1X is equal to F1Y, that is, the left and right vibration restraining force and the up and down vibration restraining force of the shock absorber 2 on the outer barrel are equal, thereby reducing the tilt vibration of the outer barrel 10.

[0045] 2. The outer barrel 10 vibrates left and right, that is, the amplitude of the left and right vibration of the outer barrel is much greater than the amplitude of the up and down vibration.

[0046] See also Fig.10 and Fig.11As shown, at this time, the electric push rod 6 rotates inward with the shock absorber 2 until the slide 4 reaches the innermost end of the adjustment slide 51. At this time, the shock absorber 2 forms an angle of 30° with the horizontal direction. The damping force applied by the shock absorber 2 to the outer barrel is F2, and the horizontal component of the damping force F2 is F2X, and the vertical component is F2Y. Because F2 is equal to F1, F2X is much larger than F1X, thereby increasing the restraining force of the shock absorber 2 on the left and right vibration of the outer barrel, thereby quickly reducing the left and right vibration of the outer barrel 10.

[0047] 3. The outer barrel 10 vibrates up and down, that is, the amplitude of the up and down vibration of the outer barrel is much greater than the amplitude of the left and right vibration.

[0048] See also Fig.12 and Fig.13 As shown, at this time, the electric push rod 6 rotates outward with the shock absorber 2 until the slide 4 reaches the outermost end of the adjustment slide 51. At this time, the shock absorber 2 forms an angle of 75° with the horizontal direction. The damping force applied by the shock absorber 2 to the outer barrel is F3, and the horizontal component of the damping force F3 is F3X, and the vertical component is F3Y. Because F3 is equal to F1 and equal to F2, F3Y is much larger than F1Y, and F3Y is much larger than F2Y, thereby increasing the restraining force of the shock absorber 2 on the up and down vibration of the outer barrel, thereby quickly reducing the up and down vibration of the outer barrel 10.

[0049] According to the above technical features, the working principle of the drum washing machine provided by the present application in the actual application scenario is as follows: when the drum washing machine is in a low-speed operation state, the outer barrel vibrates due to the eccentricity of the foreign object and the vibration monitor 11 monitors the vibration degree and vibration direction of the outer barrel 10, and transmits the detected vibration degree and vibration direction of the outer barrel 10 to the microprocessor; when the outer barrel vibrates at an angle, that is, when the up and down vibration amplitude and the left and right vibration amplitude of the outer barrel are similar, the microprocessor controls the electric push rod 6 to retract and retract through the controller to rotate the shock absorber 2 until the shock absorber 2 forms an angle of 45° with the horizontal direction. At this time, the up and down vibration restraint force and the left and right vibration restraint force applied by the shock absorber 2 to the outer barrel 10 are about The restraining forces are equal, thereby reducing shock to the outer barrel 10; when the outer barrel 10 vibrates up and down, that is, the up and down vibration amplitude of the outer barrel is much larger than the left and right vibration amplitude, the microprocessor controls the electric push rod 6 to extend through the controller, increases the angle between the shock absorber 2 and the horizontal direction, thereby increasing the up and down vibration restraining force applied by the shock absorber 2 to the outer barrel 10, and then quickly reduces shock to the outer barrel 10; similarly, when the outer barrel 10 vibrates left and right, that is, the left and right vibration amplitude is much larger than the up and down vibration amplitude of the outer barrel, the microprocessor controls the electric push rod 6 to shorten through the controller, reduces the angle between the shock absorber 2 and the horizontal direction, thereby increasing the left and right vibration restraining force applied by the shock absorber 2 to the outer barrel 10, and then quickly reduces shock to the outer barrel 10.

[0050] The drum washing machine provided in the present application has a shock absorber angle that can be adjusted according to the vibration conditions of the outer drum of the washing machine, thereby increasing the component of the damping force provided by the shock absorber in the vibration direction of the outer drum, thereby improving the shock absorption effect, and solving the problem that the shock absorbers of existing drum washing machines are all fixed, and the angle of the damping force provided by the shock absorber to the outer drum is fixed, that is, the horizontal component and the vertical component of the damping force are fixed, and cannot be adjusted according to the actual vibration state of the outer drum, which leads to poor shock absorption effect.
