Abstract
A spiral outwardly facing surface, driving surface, of a dasher forces wash almost radially outwardly with little tendency for the wash to be whirled with the dasher. Therefore, the dasher can be driven unidirectionally by apparatus that is much simpler and more economical than the gearing used for reciprocating motion in conventional washing machines. Preferably, the height of the spiral surface is low, the change in rate of curvature is gradual, and a line normal to the tangent of the outer portion of the spiral is nearly radial to propel clothes radially while the dasher is being rotated at a speed within the range of speed normally used for drying by spinning. The use of the spinning rate further simplifies the rotative driving apparatus.
