Abstract:

A dishwasher tub includes a bottom wall having a sump basin formed therein for containing a reservoir of washing fluid. The sump basin has an upper rim having a rear portion spaced inwardly from the rear edge of the bottom wall, opposite side portions spaced inwardly from the opposite side edges of the bottom wall, and a front portion spaced inwardly from the front edge of the bottom wall. The rim of the sump forms two spaced apart leg portions of the basin which extend forwardly into close proximity to the front spaced apart corners of the front wall of the tub. In addition to the sump basin, the bottom wall includes front, rear, and opposite side margins sloping upwardly from the rim of the sump basin to the rear, side, and front walls of the dishwasher tub.

Abstract:

A pump mount is provided for a dishwasher having a tub with an opening in the sump defined by a radially inwardly directed annular flange. A pump housing includes a plurality of ramp members spaced around its periphery and a seal is located between the pump housing and the flange for retaining washing fluid in the tub when the pump housing is assembled to the tub. A locking member is engageable with the pump housing ramp members for assembling the pump housing to the tub. In the preferred embodiment a locking member is rotatable relative to the pump for effecting axial movement of the pump housing relative to the tube to compress the seal and form a fluid tight joint.
