Abstract

Abstract A combination tub-wash basket for a vertical axis washing machine is an imperforate structure formed generally in the shape of a frustum of a cone mounted upon a concave base portion so as to provide an enlarged annulus chamber around the bottom of the basket. A perforate divider member is secured within the basket and is formed to provide an annular depression so as to define in the basket a clothes retaining area and a lower, washing medium retaining area. This perforate divider member is provided with vanes for imparting washing action to the clothes and a coaxial shaft for preventing large items being washed from lying across the basket. The base of the basket is provided with an axially concentric drain. When the wash basket is mounted within a machine providing a shifting nodal point, gyratory suspension system, during the centrifugal water extraction process, the annulus chamber provided at the bottom of the basket will contain water which, postcritically, will position itself therein to counter any unbalance in the basket resulting, for example, from the bunching of clothes.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 198 words
In a vertical axis washing machine, a combination tub-wash basket for receiving both items to be washed and a washing medium, and means for alternatively providing oscillatory motion and rotatable motion of the basket continuously in one direction for successive revolutions about its vertical axis, said basket comprising: a generally circular, imperforate, concave base having a drain opening at the center thereof; a generally annular, upturned edge extending upwardly from said base; a generally cylindrical, imperforate side wall portion located above said base and said edge; a perforate divider member secured within the basket above the base and below said side wall to provide an upper, item-retaining area and a lower, washing medium retaining and draining area; an annular chamber formed by said base, said edge, and said perforate divider member, said annular chamber being radially outward of the side wall portion and providing a passageway for the washing medium therearound whereby the washing liquid will position itself postcritically in the annular chamber opposite any unbalance weight caused by the items being washed; and a plurality of vanes within said upper itemretaining area for effecting washing action upon the items being washed during oscillatory motion of the basket.
Claim 2
Dependent Claim 198 words
In a vertical axis washing machine, a combination tub-wash basket for receiving both items to be washed and a washing medium, and means for alternatively providing oscillatory motion and rotatable motion of the basket continuously in one direction for successive revolutions about its vertical axis, said basket comprising: a generally circular, imperforate, concave base having a drain opening at the center thereof; a generally annular, upturned edge extending upwardly from said base; a generally cylindrical, imperforate side wall portion located above said base and said edge; a perforate divider member secured within the basket above the base and below said side wall to provide an upper, item-retaining area and a lower, washing medium retaining and draining area; an annular chamber formed by said base, said edge, and said perforate divider member, said annular chamber being radially outward of the side wall portion and providing a passageway for the washing medium therearound whereby the washing liquid will position itself postcritically in the annular chamber opposite any unbalance weight caused by the items being washed; and a plurality of vanes within said upper itemretaining area for effecting washing action upon the items being washed during oscillatory motion of the basket.
Claim 3
Dependent Claim 25 words
The wash basket of Claim 1 wherein the wash basket is mounted upon a shifting nodal point, gyratory suspension system secured within the washing machine.
Claim 4
Dependent Claim 45 words
The wash basket of Claim 2 wherein a plurality of radial fins are provided on the inside of the annular chamber of the basket and secured to the concave base for effecting a damping anti-surge action upon the washing medium when the basket is rotated.
Claim 5
Dependent Claim 40 words
The wash basket of Claim 1 wherein the imperforate side wall portion has a slightly smaller diameter at the top than at the bottom for hindering the washing medium from traveling up the side wall when the basket is rotated.
Claim 6
Dependent Claim 35 words
The wash basket of Claim 1 wherein the top of the imperforate side wall has an annular, inturned flange to define an opening in the basket for the placement therein of items to be washed.
Claim 7
Dependent Claim 50 words
The wash basket of Claim 1 wherein the perforate divider member is formed to provide an annular depression within which items to be washed will gravitate, the divider being provided with a plurality of radial vanes extending into the upper item-retaining area for effecting washing action upon items being washed.
