Abstract
A spray assembly for a dishwasher of the kind wherein utensils are disposed inside a dishwashing chamber and a generally L-shaped spray assembly is rotated to and fro so that a horizontal leg thereof sweeps across a lower surface of the dishwashing chamber and a vertical leg of the spray assembly sweeps across a side wall of the dishwashing chamber. The spray assembly has channels for conveying detergent and hot water and further has multiple nozzles disposed along the horizontal and vertical legs for directing detergent and hot water on to the utensils inside the dishwashing chamber from multiple different directions as the spray assembly rotates. A fluid inlet coupler at an end of the spray assembly is adapted for coupling to a rotatable hub having duct connectors projecting downwardly substantially parallel to an axis of rotation of the hub and fluidly coupled to respective channels of the spray assembly.
