Description

Suspension full automatic washing dewaterer

The utility model relates to a kind of washing machine, particularly a kind of have with holes can be along the rotating cylinder of X rotation, can wash and washing machine that can centrifugal dehydration.

At present, the suspension full automatic washing dewaterer that U.S. Metro company produces, it mainly comprises external frame, is installed in machine body in the external frame and the shock preventing device that is connected with external frame with machine body.Its shock preventing device adopts the air cushion anti-vibration structure, be about to the entire machine main body, comprise that washing drum, rotating cylinder and transmission mechanism thereof be satisfied with on several (being generally three) rubber pneumatic bag (being air cushion) shock absorbers, pneumatic buffer then is satisfied with on the external frame bottom, the relative external frame of machine body is in complete suspended state, without any rigid fulcrum.The energy overwhelming majority of washing machine when running machine body vibration is absorbed by air cushion, has only minimum part to be transferred on the external frame, makes external frame only produce slight vibration, so air cushion can produce and keeps away the effect of shaking preferably.But also there are three defectives in this air cushion shock preventing device: one, use rubber pneumatic bag shock absorber not only needs to increase the charger to air bag, and in washing, the uniform placement of fabric, dewater, get the blowing pressure that needs to regulate air bag in the different operating process such as clothing, in washing procedure control, increased trouble; Its two, air-bag shock absorber is located at the bottom of machine body, the strong point of machine body is far away from its center of gravity, makes machine body when running poor stability; Its three, air-bag shock absorber is under the surge for a long time works, and requires it to have good withstand voltage properties, its manufacture craft and production cost are very high, moreover at present still do not have this series products in China.

The purpose of this utility model provides a kind of shock preventing device good damping result, simple in structure, easy making, with low cost, durable suspension full automatic washing dewaterer.

For achieving the above object, the utility model is achieved in that a kind of suspension full automatic washing dewaterer, it comprises external frame, be installed in the machine body in the external frame, and the shock preventing device that is connected with external frame with machine body, wherein said shock preventing device is by being located at a machine and an external frame left side respectively, be the spring shock absorber of symmetric arrangement between the right side and be located at machine body respectively and external frame before and after be the hydraulic bjuffer that is symmetrically arranged between the side and form, the spring shock absorber is connected between external frame and the machine body, the dead load of machine body is supported on the external frame, the set engaging lug in the upper end of hydraulic bjuffer and machine body bottom is connected, and the set ear seat in its lower end and external frame bottom is connected.

In the utility model, the spring shock absorber holds up the static load of machine body and suspension relatively fully, when machine run, external frame is not produced rigid impulsive force like this, even machine body has bigger heavy curtain moving, its produce power major part is absorbed by the spring shock absorber, and is very slight to the external frame influence; Though hydraulic bjuffer itself does not bear the static load of machine body, when the load at its two ends produces relative motion, that is when producing vibrational loading, under the effect of the damping unit of buffer, vibration amplitude is subject to significant restrictions.So the shock preventing device of being made up of spring shock absorber and hydraulic bjuffer has the good effect of shaking of keeping away, and this shock preventing device also has simple in structurely, produces easily, and cost is few, long service life, and maintain and replace easily makes advantages such as the machine body running is stable.
