Dishwasher with food particle macerator and mincer

Abstract

A dishwasher sump is divided into a collection chamber and a pump chamber by a filter. Food particles collect in the collection chamber while filtered wash liquid collects in the pump chamber. A pump has an inlet located in the pump chamber. The filtered wash liquid is recycled and sprayed on objects in the dishwasher by the pump. The impeller is driven by a shaft extending through the collection chamber and a wall separates the pump chamber from the collection chamber. Food particles in the collection chamber are minced by a rotating blade on the pump shaft. Balancing vanes on a rear face of the impeller prevent food particles and dirty water from flowing into the filtered liquid from the collection chamber. At the end of a wash cycle, the minced food particles are pumped to a drain with the wash liquid.
