Title:
WASHING MACHINE
Document Type and Number:
Japanese Patent JPS5563685
Kind Code:
A
Abstract:
A vane shape for producing optimum washing action in vertical axis clothes washing machines including vanes located in the bottom of the tub or basket and shaped with radially canted edges which cause the fabric articles to be pulled and slid outwardly as the edge is rotated into the articles to establish a toroidal circulation within the tub. In a preferred embodiment, an oscillated agitator is provided with a series of vane pairs joined at the lower side to form a V-shaped trough with either upper edge of the vane pairs inclined to produce a net outward movement of the washed articles by alternate engagement with a respective upper edge of either vane blades upon alternate rotation into the load. The vane shapes are either mounted to an oscillating agitator, a rotary impeller, or integrally formed in an oscillating basket. An arrangement for attenuating the action of the vane shapes is provided either by movable intermediate spoiler vanes or the combination of a reduced size vane agitator is used for gentle wash loads, with a slip-over agitator having vanes of normal size. Variations in the vane arrangement include asymmetrically sized vane pairs which balance torque variations in the agitator drive mechanism, and a snap-in lint filter occupying the space between vane pairs; additional radially extending vanes which augment the circulating effect by drawing the clothing articles downwardly along the agitator post and into engagement with the vane shapes; and a vane shape for agitators which simplifies molding of the agitator.
