Abstract
A tub for a laundry appliance, includes a rear wall having a bearing hub for receiving a drive shaft. A plurality of inner radial walls extend from the bearing hub to a convergence wall. A circumferential wall extends concentrically about the bearing hub to engage one of the inner radial walls and the convergence wall. A plurality of outer diverging walls extends from the convergence wall to an outer edge of the rear wall.

A tub for a laundry appliance, the tub comprising:
- a rear wall having a bearing hub for receiving a drive shaft;
- a plurality of inner radial walls that extend from the bearing hub to a corresponding convergence wall of a plurality of convergence walls;
- a circumferential wall that extends concentrically about the bearing hub to engage one of the inner radial walls and the plurality of convergence walls;
- and
- a plurality of outer diverging walls that extends from the plurality of convergence walls to an outer edge of the rear wall.
A tub for a laundry appliance, the tub comprising:
- a rear wall having a bearing hub for receiving a drive shaft;
- a plurality of inner radial walls that extend between the bearing hub and a circumferential wall;
- and
- a plurality of outer diverging walls that extend between the circumferential wall and an outer edge of the rear wall, wherein each of the inner radial walls are positioned out of alignment with each of the outer diverging walls.
A tub for a laundry appliance, the tub comprising:
- a rear wall having a bearing hub for receiving a drive shaft;
- a plurality of inner radial walls that extend outward from the bearing hub to respective T-shaped reinforcements, each of the respective T-shaped reinforcements having a concentrically extending wall with opposing ends;
- and
- outer diverging walls that extend outward from each opposing end of each T-shaped reinforcement to an outer edge of the rear wall.
