Embodiment 1

[0044] see below image 3 , which is a front view structural diagram of Embodiment 1 of the suspension rod connection method of the shock absorption system of the present invention; The upper end of the rod hanging head 50 is connected and fixed. In this embodiment, the upper end of the suspender 5 is bent to form a suspender elbow 51, and the suspender elbow 51 is in contact with the upper end surface of the suspender head 50, and is connected by welding or other means to strengthen the connection between the suspender 5 and the The connection strength of the hanger 50 of the suspender prevents the hanger 5 from being separated from the hanger 50 when the suspender 5 is compressed or stretched.

[0045] In this embodiment, the suspender 5 and the suspender hanger 50 between the different shock absorbers are independently provided, and the two shock absorbers are connected through the connecting pipe 6 .

Embodiment 2

[0047] read on Figure 4 , which is a front view structural schematic diagram of Embodiment 2 of the suspension rod connection method of the shock absorber suspension rod device of the present invention; image 3 The first difference is that in this embodiment, at least two shock absorbers share a section of suspender 5 and suspender hanger 50, and a connecting piece 7 is connected between the independent sections of the two suspenders, and, The connecting piece 7 is connected with the common section of the two suspenders. like Figure 4 As shown, the upper end of the first shock absorber 211 is connected with the first suspension rod 54, the upper end of the second shock absorber 221 is connected with the second suspension rod 55, the first suspension rod 54 and the second suspension rod 55 are independently arranged, and The connecting piece 7 is connected with the common suspension rod 5 and is connected with the casing 10 of the washing machine through the suspension rod...

Embodiment 3

[0071] see below Figure 7 , which is a schematic cross-sectional structure diagram of the third embodiment of the shock absorbing system of the present invention; the difference between the third embodiment and the second embodiment above is that a static pressure hole 38 is provided on the outer wall circumference of the damping block 3, and the static pressure hole The diameter of 38 is smaller than the diameter of the damping hole 34; the liquid with pressure entering the interior of the damping block 3 will flow out along the static pressure hole 38 on the outer wall of the damping block, filling between the outer wall of the damping block 3 and the inner wall of the cylinder 2 In the gap, the effect of hydrostatic bearing is formed between the outer wall of the damping block 3 and the inner wall of the cylinder 2 . In this embodiment, the hydraulic oil in the first chamber 21 is pressurized by using the damping block 3 to move in the damper, especially moving upward, and...

Abstract

The invention relates to a washing machine, and specifically provides a shock absorber system and a washing machine including the shock absorber. The invention aims to solve the problem that the damping force of each shock absorber in the existing shock absorbing system is different, resulting in poor shock absorbing effect. For this purpose, the shock absorber system of the present invention comprises at least two shock absorbers, the cavity of each of which is filled with fluid, each of which is flow to generate shock absorption and damping, characterized in that the inner cavity of one of the at least two shock absorbers communicates with the inner cavity of the other shock absorber through a pipeline. In the case of adopting the above-mentioned technical features, the present invention connects at least two shock absorbers through connecting pipes, so that the damping liquid in each shock absorber can circulate, balance the damping force generated by each shock absorber, and enhance the shock absorption effect .

Description

technical field [0001] The invention belongs to the technical field of washing machines, and specifically provides a shock absorbing system and a washing machine including the shock absorbing system. Background technique [0002] Existing washing machines, whether they are pulsator washing machines or drum washing machines, always produce unpleasant vibrations and noises during operation, causing unnecessary disturbance and distress to consumers, and causing a series of complaints. How to optimize and reduce the vibration and noise of the washing machine is a very urgent problem for consumers. [0003] On solving the problem of excessive vibration and noise when the washing machine works, the invention patent application with the publication number CN1718902A discloses a "damper for washing machine". Specifically, the damper for a washing machine includes a cylinder and a piston rod inserted in the cylinder, the end of the piston rod is provided with a piston, and the pisto...
