Vertical soil separator for dishwasher

摘要

A dishwasher structure having a centrifugal pump for providing dishwashing liquid to a spray arm thereof. The swirling motion of the dishwashing liquid effected by operation of the pump is utilized to divert a portion of the liquid to an accumulator wherein soil material is collected from the liquid. The cleansed liquid is returned to the pump chamber to be repumped with additional dishwashing liquid. The soil accumulating chamber is arranged concentrically about a guide chamber, in turn arranged concentrically about the pump chamber to provide a compact coaxial liquid cleansing structure. A drain is provided for draining the dishwashing liquid and collected soil at the end of the dishwashing cycle.
