Apparatus for dispersing washing water of a dishwasher

An apparatus for dispersing a washing water of a dishwasher comprising:

• a dispersing nozzle arm including a connecting conduit rotatably connected to a pump for supplying a washing water, a plurality of dispersing apertures which are formed on an outer circumference surface thereof and arranged in a longitudinal direction thereof, both ends of said dispersing nozzle arm being opened so that the washing water is dispersed through the dispersing apertures;
• a first nozzle body, into which an end of said dispersing nozzle arm is inserted, including a plurality of first assistance spray apertures formed on an outer circumference surface thereof, a first connecting protrusion opposite to the first assistance spray apertures, and a first jet aperture formed on the outer circumference surface between the first assistance spray apertures so that the washing water is ejected from the first jet aperture and the ejection of the washing water rotates said dispersing nozzle arm, said first nozzle body sliding on the outer circumference surface of said dispersing nozzle arm;
• a second nozzle body, into which other end of said dispersing nozzle arm is inserted, including a plurality of second assistance spray apertures formed on an outer circumference surface thereof, a second connecting protrusion opposite to the second assistance spray apertures, and a second jet aperture formed on the outer circumference surface between the second assistance spray apertures so that the washing water is ejected from the second jet aperture and the ejection of the washing water from the second jet aperture rotates said dispersing nozzle arm in cooperation with the ejection of the washing water from the first jet aperture, said second nozzle body sliding along on the outer circumference surface of said dispersing nozzle arm, the first and second jet apertures being formed in opposite directions with respect to each other as to spray the washing water in opposite directions;
• a guiding part for sliding said first and second nozzle bodies along the outer circumference surface in the lengthwise direction of said dispersing nozzle arm when said dispersing nozzle arm rotates, said means being installed on a bottom wall of said dishwasher and including:
• a guide rail installed on the bottom wall of said dishwasher;
• a pair of followers for sliding said first and second nozzle bodies along the outer circumference surface of said dispersing nozzle arm while moving along said guide rail, and having a guide slit into which said guide rail is inserted and a connecting groove into which said first and second nozzle bodies are respectively inserted, the guide slits being formed at an upper portion of said followers and the connecting grooves being formed at a lower portion of said followers;
• and
• a plurality of balls for reducing friction between the guide slit and the guide rail while said balls move along said guide rail.
