Description

The pulsator washing machine suspended structure
Technical field
The present invention relates to be applied in the suspension arrangement in the pulsator washing machine, the suspension arrangement that carries out between the casing of the rotary drum washing machine of more specifically saying so and the outer bucket.
Background technology
At present, the outer bucket of full-automatic pulsator washing machine at the end part placement be: the rotating shaft on the clutch places the center of dehydration barrel and outer bucket, considers scrubbing space, generally motor is biased in one side of outer bucket assembly.Heavier part is exactly motor and clutch on the outer bucket assembly, and the motor biasing must cause outer bucket assembly to depart from level; Dehydration barrel is rotation at a high speed during the full-automatic pulsator washing machine dehydration, in order to keep dynamic equilibrium, need be to be hanging on the casing the inside and outside bucket of washing machine with a cover suspension arrangement, there is shock-absorbing spring at the outer bucket position that the suspension arrangement lower end connects, plays the effect of support, absorbing and reduction noise.The offset bit at the bottom of bucket of motor is equipped with two kinds: a kind of is to arrange along the suspension arrangement diagonal, four configurations that hanger rod part is 1 to 3 combination in the suspension arrangement, the parameter that promptly is in a suspension rod of motor one side is different from the parameter of each root suspension rod at other three corner locations place; Another kind is to be symmetrically arranged along suspension arrangement, four configurations that hanger rod part is 2 to 2 combinations in the suspension arrangement, and promptly the parameter of two suspension rods of motor side is different from the parameter of the suspension rod on other two corner locations.This suspension arrangements scheme compares: its common ground is: four length of boom unanimities, on casing with outside the position height unanimity that is connected on the bucket, shock-absorbing spring coefficient of elasticity unanimity, the number of turns of the shock-absorbing spring in the suspension rod of motor side is more than the shock-absorbing spring number of turns in the non-motor side suspension rod.Difference is: sharing the bucket portion that causes owing to motor biasing, to adorn one of out-of-level hanger rod part be one, and another is two.
At present, the vibration-proof structure of suspension arrangement lower end generally has following three kinds: the one, and full open model as shown in Figure 1, each formation is respectively among the figure: suspension rod 1, ball-type seat 2, shock-absorbing spring 3 and spring base 4; The 2nd, semi open model shown in Figure 2, each member is respectively among the figure: suspension rod 1, ball-type seat 2, shock-absorbing spring 3, spring base 4, tensioner spring 5 and packing ring 6; The 3rd, as shown in Figure 3 closed, each member is respectively among the figure: suspension rod 1, ball-type seat 2, shock-absorbing spring 3, spring base 4, felt pad 5, end cap 6, vibration isolation rubber 7, packing ring 8 and sealing strip 9.
