Abstract

See full text

A dishwasher with a spray agitator (1) rotating about an axis (2) in alternating opposite directions due to the effect of two nozzles with opposite thrusts (6,7). The nozzles are alternately fed with water under pressure by means of a rotating shutter (13). The shutter is made to rotate by reduction gears (12,14) and a rotor (11) activated by a nozzle (8) provided inside the agitator (1). The dishes are washed efficiently even if a mechanical obstruction interferes with the agitator.
