Spray assembly and replaceable detergent container for dishwasher

A dishwasher comprising:

• a dishwashing chamber and an L-shaped spray assembly that is rotated about a vertical axis so that a horizontal leg of the L-shaped spray assembly sweeps across a lower surface of the dishwashing chamber and a vertical leg of the L-shaped spray assembly sweeps across a side wall of the dishwashing chamber,
• the spray assembly having channels for conveying detergent and water and further having multiple nozzles disposed along the horizontal and vertical legs of the L-shaped spray assembly for directing detergent and water on to the utensils inside the dishwashing chamber from multiple different directions as the spray assembly rotates, and
• a fluid inlet coupler at an end of the horizontal leg of the L-shaped spray assembly adapted for coupling to a rotatable hub of the type having duct connectors projecting downwardly parallel to an axis of rotation of the hub and fluidly coupled to respective channels of the spray assembly;
• wherein the fluid inlet coupler is integrally molded with the horizontal leg of the spray assembly and comprises for each channel thereof a respective downwardly projecting inlet integrally formed with said channel, each of said inlets being adapted to couple and to seal to respective ones of the duct connectors.

• and
• at least one detergent reservoir each fluidly connected via a respective filler tube to a respective trough at an upper end of the dishwasher, there being further provided in fluid communication with said trough a bottle mount dimensioned to accommodate a neck of a detergent bottle of the type having a one-way valve in a side thereof toward a base of the bottle, the one-way valve allowing for free entry of air when the bottle is emptied of detergent, the bottle mount having an upwardly projecting tube adapted to pierce a seal in said neck thereby allowing detergent to flow under gravity alone from the bottle to the reservoir.
