ABSTRACT:
A wash/rinse system for a drawer-type dishwasher includes a wash mechanism having a paddlewheel and a spray bar mounted in a washing chamber of the dishwasher. The spray bar includes at least one nozzle that is positioned so as to deliver a jet of washing fluid onto a deflector member provided on the paddlewheel. Upon impacting the deflector member, the jet of washing fluid diverges into streams of washing fluid which are sprayed onto articles positioned in the washing chamber. Preferably, the spray bar includes a plurality of nozzles which direct multiple jets of washing fluid onto a corresponding plurality of deflector members. The paddlewheel is mounted so as to create random streams of washing fluid that are sprayed into the washing chamber to combine with washing fluid emanating from a lower wash arm to clean articles in the washing chamber.
