ABSTRACT:
This invention includes apparatus that circulates and agitates a liquid cleansing solution in a sink by means of gas jet bubbles, in order to clean dirty articles therein. The basic device comprises a base structure, a pressurized gas supply, hollow jet nozzle means disposed in the sink, the jet nozzle means having a sealed end and a plurality of apertures thereon for gas ejection, so as to produce gas bubble jet streams which scrub and clean the articles by both article impact and agitation of the liquid cleansing solution. Preheating of the pressurized gas, coupled with a manifolded heat exchanger in the cleansing solution, provides the means for heating the cleansing solution. Temperature control means are then used to maintain the temperature of the cleansing solution against cooling. Alternately, the heat source may include a separate liquid heater. The warmed gas may also be used to dry the articles after washing.
