DISH WASHING MACHINE Russian patent published in 2003 - IPC

FIELD: domestic equipment. SUBSTANCE: dish washing machine has tank with overflow vessel, curved drain pipe having curved portion positioned at level higher than overflow level, supersonic emitters, overflow channel of increased section, overflow channel of reduced section, nozzles for supplying of small amounts of water, nozzles for supplying of increased amounts of water, electric hydraulic valves, dish receiving container, hydraulic cylinder, control unit, detergent hopper, filter, connecting pipelines, and drain hose. Detergent containing hot water is supplied from above via nozzles into tank and supersonic emitters are actuated. Then water is supplied from below by means of nozzles in order to remove light fat contaminants through overflow vessel and channel. Upon filling up of overflow vessel, liquid is automatically drained through curved drain pipe and simultaneously heavy contaminant particles are removed from tank. Rinsing operation is provided by repeating the process with the only difference that cold water is supplied into tank. Upon draining of water, hydraulic cylinder raises container with clean dishes. EFFECT: increased efficiency by reduced concentration of detergent solution contaminants and high automation level. 1 dwg
