Abstract
A method of washing clothes in an automatic washer having an imperforate wash tub, a perforate wash basket disposed within the tub and rotatable about a vertical axis and a bottom plate disposed within the lower portion of the wash basket and mounted for wobbling motion. The method of operation of the washer includes loading the clothes into the wash basket, adding water and detergent into the tub for forming wash liquid, recirculating the wash liquid over the clothes while driving the bottom plate in a nutating movement. Nutating movement describes the movement of the bottom plate wherein the bottom plate is slowly rotated within the wash basket while being driven in a rapid wobbling motion. In this fashion, the clothes are repeatedly moved under a spray pattern of wash liquid while being jostled and flexed for achieving he desired excellent soil removal.
