Inner inclined suspension type vibration avoiding system for shell and barrel integrated full automatic impeller washing machine

Abstract

A fully automatic pulsator washing machine with shell and barrel integrated into one obliquely suspended vibration isolation system includes a shell barrel, a base, a dehydration barrel, a pulsator, a rubber corrugated water sealing plate, an elastic air resistance shock absorber, an electrical device, a sleeve shaft, Frame plate, machine base, large ring flange, small ring flange. The key of the present invention is: the cable end of the elastic air resistance shock absorber that is suspended on the machine base is obliquely hung in the four-corner hanging holes of the frame plate towards the inner side of the machine base. Therefore, this structure is called the inner inclined hanging type, and the angle α between the axis of the rope and the axis of the sleeve shaft is preferably 0-10°; at the same time, the elastic air resistance shock absorber adopts rope traction to make the whole system avoid The vibration effect is better. After the present invention adopts the inner inclined hanging structure, it better solves the problem of vibration avoidance during the operation of the full-automatic pulsator washing machine with shell and barrel in one, especially during dehydration; comparative experiments prove that even if the clothes are seriously eccentric during dehydration , the amplitude of rotation of the dehydration barrel of the inner inclined hanging type vibration-proof washing machine of the present invention is much smaller than that of the outer inclined hanging type and the lifting type vibration-proofing manner. The adoption of the inner inclined suspension type vibration isolation method makes it possible to realize the practical mass production of the fully automatic pulsator washing machine with the shell and bucket integrated into one.

Description

technical field [0001] The invention relates to a vibration isolation method, in particular to an oblique suspension type vibration isolation system applied in a full-automatic pulsator washing machine with a shell and barrel integrated into one. Background technique [0002] Existing full-automatic pulsator washing machine is to suspend the water tub (inner bucket) on the four corners of the shell by the shock absorber, therefore, this type of washing machine must have a shell to support the shock absorber to eliminate the vibration that the washing machine produces during work. The fully automatic pulsator washing machine with a shell and a barrel has eliminated the traditional shell parts, and combines the water tub and the shell into one, becoming a fully automatic pulsator washing machine with a new structure. Therefore, how to eliminate such The problem of vibration generated by the washing machine at work has been raised. Such as the patent number: Zhao 51-122000 Jap...

AI Technical Summary

Problems solved by technology

Among the above-mentioned representative two types of vibration isolation methods, the anti-vibration effect of the external inclined suspension type is better than that of the lifting type. In the slightly eccentric rotation of the center of gravity, it has the effect of amplifying the amplitude (experimental confirmation, this article will not repeat it); although the external inclined hanging type has a fairly good vibration-proof effect, if the eccentricity of the clothes in the dehydration bucket is slightly large, When the dehydration is rotated, the dehydration bucket collides with the shell ("knocking the cylinder"). If the gap between the dehydration bucket and the shell (barrel) is increased to improve, the overall size of the washing machine will become too large, which improves the washing machine. The manufacturing cost increases the washing water, and the noise is not reduced. The advantage of the new product is cheap and water-saving is lost. This is an important factor why the fully automatic pulsator washing machine with shell and bucket has not been mass-produced and practical for a long time.
