  • Patent number: 7493907
    Abstract: An improved nozzle assembly for a dishwasher is provided. The nozzle assembly includes first and second nozzles rotatably installed adjacent to corresponding first and second racks so as to selectively spray water in first and second directions. One of the nozzles includes a device for manually setting the spraying direction, including a fixed central piece and first and second nozzle sections. The fixed central piece is in communication with a water circulator, and supplies water to the first and second nozzle sections. An open end of each nozzle section is rotatably coupled to an open end of the fixed central piece, and the first and second nozzle sections may be rotated using a manual setting device so as to direct a spray of water in different directions.
