Abstract

A laundry treating appliance having a tub with a tub ring and a drum located within the tub having a balance ring. The tub ring may extend radially inward and be spaced above the balance ring. The tub ring and balance ring may have an angled portion to provide for a generally constant space between the tub ring and balance ring during rotation of the drum within the tub.

First claim

What is claimed is:

1. A laundry treating appliance, comprising:
a cabinet defining an interior;
a tub comprising a peripheral wall terminating in a peripheral edge to form an opening to an interior of the tub for holding liquid;
a drum located within the interior of the tub, comprising a peripheral wall terminating in a peripheral edge to form an opening to an interior of the drum for receiving laundry for treatment, and rotatable about an axis;
a tub ring mounted to the peripheral edge of the tub defining a first arc as the tub deviates from the axis about a first point, the tub ring having a first angled portion extending inwardly and upwardly from the peripheral edge of the tub at a first angle; and
a balancing ring mounted on the peripheral edge of the drum defining a second arc as the drum deviates from the axis about a second point which is a common point with the first point, the balancing ring having a second angled portion extending inwardly and upwardly from the peripheral edge of the drum at substantially the first angle while the appliance is not operating,
wherein the first and second angled portions are separated by substantially a minimum distance that generally prevents contact of the first and second portions while the appliance operates, and
wherein the first and second arcs do not intersect while the appliance operates.

2. The laundry treating appliance of claim 1 wherein the angled portion of the tub ring overlies the peripheral edge of the drum.

3. The laundry treating appliance of claim 2 wherein the angled portion of the tub ring extends at an angle of about 35 degrees relative to a horizontal reference line.

4. The laundry treating appliance of claim 2 wherein the tub ring further comprises another portion that extends radially inward from the angled portion of the tub ring.

5. The laundry treating appliance of claim 4 wherein the tub ring further comprises a groove that receives the peripheral edge of the tub to mount the tub ring to the tub.

6. The laundry treating appliance of claim 1 wherein the first and second arcs never intersect.
