Description
Technical field
The utility model relates to the suspension arrangement that is applied 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.
Vibration during laundry machine dehydration mainly is that the motion of dehydration barrel causes, dehydration barrel is coupling mutually with the motion of outer bucket assembly.The motion of desirable dehydration barrel can be approximately the motion of the heavy rigid body high speed time rotational of symmetry, comprise precession and nutating, and the amplitude of precession is more much bigger than the amplitude of nutating.And the size of precession amplitude depends on primary condition, the verticality that also promptly depends on the dehydration barrel rotating shaft, dehydration barrel is consolidated with nut with outer bucket assembly, so the suspension of bucket assembly is extremely important to the control of levelness outside hanging, directly influences the vibration of washing machine.
Dispose no matter be 1 to 3 combination or 2 to 2 combinations for the suspension rod of washing capacity at the type below six kilograms, because motor weight is relatively light, outer bucket relative diameter is smaller, overcoming the out-of-level state that motor biasing causes is easier to realize that the difference of two kinds of allocation plans aspect vibration of washing machine is little by the shock-absorbing spring number of turns ratio of adjusting on the suspension rod.But to closed, noise reduces the vibration-proof structure mode of ball-type seat successively from full open model, semi open model, and cost raises successively, and the assembly technology complexity raises successively.
In the configuration of the suspension rod of the type more than six kilograms, take 1 to 3 to make up that to be combined in the difference of vibration aspect apparent in view with taking 2 to 2 for washing capacity.Because motor weight is relatively heavy, outer bucket relative diameter is bigger, and it is difficult to realize by the shock-absorbing spring number of turns of adjusting on the suspension rod to overcome the out-of-level state that the motor biasing causes, takes 2 to 2 combinations to be better than and takes 1 to 3 to make up.
The shock-absorbing spring coefficient of elasticity of four suspension rods is the same in the suspension arrangement that prior art adopts, the number of turns of motor side and non-motor side shock-absorbing spring is different, because motor is heavier and outer bucket diameter is bigger, cause the number of turns of shock-absorbing spring difference bigger, so, washtub tilted when the shock-absorbing spring of washtub four suspension rods when full load was compressed to the limit, the clothing that washs after washtub washing and rinsing finish arrange water tilts, and setovers and causes that washtub precession amplitude is big owing to clothing during laundry machine dehydration, vibration Da Yi collides casing or hits the safety switch that stops setovering and makes washing machine not stop the moisturizing rest and reorganization.
