Abstract
An automatic washer for washing garments comprises a wash basket with an open top defining a wash chamber, and a clothes mover mounted in the washer for reciprocal movement about an axis of rotation within the wash chamber. The clothes mover comprises an apron, and at least one vane extending from the apron and defining a working surface having an upper edge and a lower edge, the upper edge and the lower edge extending from an outer end to an inner end. At least one line lying along the working surface and extending between the outer end and the inner end defines a constant angle of attack relative to the direction of movement of the clothes mover. The working surface is configured to move the garments along the working surface at a substantially instantaneously uniform speed. The configurations of the upper surface and the working surface are optimized to move the garments between the perimeter and the axis of rotation while minimizing force acting on the working surface. The working surface defines a local draft angle that increases from the outer end to the inner end.
