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.

Abstract:

A household laundry appliance is provided for washing and drying individual pieces of laundry. The appliance includes a bin for holding laundry, wash and dry stations, and a robotic feeder mechanism to automatically convey laundry from the bin to the processing stations. The wash stations include a spray station for spraying the garments with a cleaning solution, and an ultrasonic station for applying ultrasonic vibrations to the garments. Rinse and extraction stations are provided upstream from the drying station to rinse the garments and then extract water from the garments. The garments are continuously transported through the appliance by a series of mesh conveyor belts between which the garments are sandwiched. The drying station includes fans for blowing heated air past the clothing to drive moisture out of the clothing. The temperature and velocity of the air may be adjusted to accommodate different garment materials and dampness. A controller interacts with sensors and actuators to control the operation of the appliance.
