Spiral vane clothes mover

An automatic washer for washing garments, comprising:

• a wash basket with an open top defining a wash chamber and having a substantially vertical axis of rotation;
• and
• a clothes mover mounted in the washer for reciprocal movement about the substantially vertical axis of rotation within the wash chamber, the clothes mover comprising:
• an apron;
• 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;
• wherein the working surface is shaped such that 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 move the garments along the working surface at a substantially instantaneously uniform speed.

An automatic washer for washing garments, comprising:

• a wash basket with an open top defining a wash chamber;
• a clothes mover provided within the wash chamber, the clothes mover comprising:
• an apron having a perimeter mounted for rotation about an axis of rotation and having an upper surface with a parabolic cross section in a plane containing the axis of rotation;
• 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;
• wherein the upper surface and the working surface are shaped to move the garments between the perimeter and the axis of rotation to reduce the force acting on the working surface.
