ABSTRACT:
In a clothes washer, liquid pulses are delivered to a bucket or tank of water to create continuously re-circulating flow therein in a vertical plane. Air is introduced into the water pulses and forms air bubbles in the tank which attract dirt particles and carry them to the surface where they are removed as part of a continuous surface overflow. In a preferred embodiment the liquid pulses are delivered by a novel fluidic oscillator of the feedback type in which air is continuously entrained by the power stream from each feedback passage in alternation. In one form, the oscillator utilizes scoop-type feedback passages between respective outlet passages and control ports, each feedback passage communicating with an air passage. In a second form of oscillator the feedback passages are of the suction type which are aspirated by the liquid outflow through respective oscillator outlet passages.
