Patent ID: 8746261

Claim:
A dishwashing machine comprising: a spray arm, a sump positioned below the spray arm for collecting fluid and soil particles, a housing in fluid communication with the sump and the spray arm, the housing having an inner chamber, a filter enclosing a hollow interior and positioned in the inner chamber and fluidly dividing the inner chamber into a first part that contains filtered soil particles and a second part that excludes filtered soil particles and operable to rotate about a longitudinal axis, the filter having an outer surface, a wash pump including an impeller operably coupled to the filter, the impeller being operable to rotate about the axis, and a flow diverter positioned in the inner chamber, the flow diverter having a tip spaced apart from the outer surface of the filter so as to define a gap, wherein the rotation of the impeller advances fluid through the filter into the hollow interior and during rotation of the filter, an angular velocity of fluid advanced through the gap is increased relative to the angular velocity of the fluid prior to entering the gap.
