Abstract (en)
A combination drain pump/disposer is used with a vessel such as a dishwasher and includes a housing (120) defining a pump chamber (126), an inlet (70) above the housing which communicates with the vessel, a pump outlet (131) extending through a side wall (128) of the chamber and communicating with a drain line, and a waste impeller (138) positioned within the chamber. The impeller (138) includes a disk-shaped base (139) substantially parallel to and spaced slightly above the floor (129) of the chamber, a plurality of soil-sizing holes (152), an upstanding rim (141) extending about a periphery of the base and including an inner wall (143) defining a plurality of radially-extending, substantially vertical pumping vanes (150,151), and at least one breaker tooth (153) extending upwardly from the base and positioned inwardly of the rim. The housing includes a cover plate (157) having an opening concentric with the impeller and at least one stationary tooth (161) providing a vertical cutting edge (162,163) extending downwardly adjacent the inner wall such that rotation of the impeller causes the cutting edges and breaker tooth to pass by the stationary tooth to perform a shearing and cutting function.
