Abstract

A laundry treating appliance for treating fabric according to a cycle of operation includes a cabinet defining an interior, a wash tub within the interior and having a peripheral wall with an upper portion and a bottom end closed by a base; a wash basket located within the wash tub for movement relative thereto and defining a laundry treating chamber; and a drive motor located within the cabinet for rotating or oscillating the wash basket. Prior to installation of the wash tub in the cabinet, the wash tub is oversized relative to the interior. After installation of the wash tub in the cabinet, the upper portion of the wash tub forms a press fit with the cabinet such that the upper portion of the wash tub exerts a force on the cabinet.

First claim

What is claimed is:

1. A laundry treating appliance for treating fabric according to a cycle of operation, comprising:
a cabinet defining an interior;
a wash tub within the interior and having a peripheral wall with an upper portion and a bottom end closed by a base, wherein the wash tub is oversized relative to the interior such that at least one first dimension of the upper portion of the wash tub is larger than at least one second dimension of the interior prior to installation of the wash tub in the cabinet;
a wash basket located within the wash tub for movement relative thereto and defining a laundry treating chamber; and
a drive motor located within the cabinet for rotating or oscillating the wash basket;
wherein the upper portion of the wash tub is press fit within the cabinet at the at least one first dimension and the at least one second dimension after installation of the wash tub in the cabinet.

2. The laundry treating appliance of claim 1 wherein the press fit includes a bearing interface that allows vertical translation of the wash tub with respect to the cabinet during the cycle of operation.

3. The laundry treating appliance of claim 2 wherein the bearing interface allows vertical translation ranging from 20 millimeters to 75 millimeters.

4. The laundry treating appliance of claim 1 further including a liner or a foam pad disposed between the cabinet and the wash tub.

5. The laundry treating appliance of claim 1 further including a plurality of suspension rods coupling the base of the wash tub to an upper portion of the cabinet.
