Abstract
A water spray system for dishwasher with an upper dish rack and a lower dish rack, with each said dish rack being mounted for selective movement forwardly out the open front. A spray tube is rotatably mounted on the bottom of each lateral side portion of each said dish rack and has a plurality of spray outlets spaced along the tube and directed generally tangentially in the same direction for causing rotation of the tube. A water supply manifold extends up the rear wall of the dishwasher. A releasable water connection device and conduits mounted on each dish rack connect the manifold to the spray tubes for supplying the water from a pump. Spray spinners are centrally mounted below each dish rack. The spray tubes provide a thorough spray at the lateral sides that the spinners may not reach in a very wide dishwasher. Other rotating spray tube arrangements are also disclosed.
