Abstract
Official abstract text for this publication.
A washing machine includes an inner tub arranged in an outer tub and a rotatable wave wheel. As every 1 kg load is increased, the height difference h 1 between the clothes and water satisfies the formula h 1 =(πD 2 h−4V 1 )/(KπD 2 ), wherein D is the diameter of the inner tub, h is the height of the wave wheel, V 1 is the volume of the wave wheel, and K is the optimal clothes load between the wave wheel and the inner tub within the wave wheel height. The clothes overturn periodically while rotating along with the wave wheel. The clothes move towards the center of the wave wheel along the wave wheel while moving upward, overturn outwards in a uniform wobble way after reaching the climax of the wave wheel and fall to the bottom of the inner tub along the inner tub wall, and move towards the center of the wave wheel again.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pulsator-type washing machine utilizing a uniform washing force comprising: an outer tub for containing water, an inner tub arranged in the outer tub for containing clothes, a rotatable wave wheel, and a drive device for controlling the rotation of the inner tub and the wave wheel, wherein: the wave wheel is a disc-shaped structure gradually rising up towards the center from its edge, on which a projection for guiding the clothes to the cente…
