1. A laundry machine comprising:
- a cabinet;
a wash tub supported within the cabinet;
a motor suspended beneath the wash tub;
a wash basket rotatably supported within the wash tub and drivingly connected to the motor;
a wash plate disposed in a bottom of the wash basket and defining an outer periphery and comprising;
a central hub encircled by the outer periphery;
a plurality of vanes extending substantially radially from the central hub toward the outer periphery, the vanes comprising a pair of side walls diverging as they extend away from the hub, the vanes having a continuously increasing width as they extend radially away from the hub; and
apertures through the wash plate and immediately adjacent the vanes; and
wherein the wash plate is rotatably supported in the wash basket and drivingly connected to the motor to oscillate the wash plate such that cloth items directly above the wash plate are frictionally dragged in an oscillatory manner and the cloth items rollover within the wash basket along an inverse toroidal rollover path, the cloth items are drawn against the vanes by a suction induced through the apertures.

Abstract
A laundry machine configured to supply a first amount of water to the wash tub wherein a wash plate can be oscillated such that clothes items directly above and in contact with the impeller are frictionally dragged in a oscillatory manner with the wash chamber while continuing to oscillate said wash plate, an additional supply of water is added to said wash tub such that as cloth items lost frictional engagement with the wash plate, the cloth items continue to move along an inverse toroidal rollover path at higher water levels.
