Abstract: A dishwasher comprising: a cleaning tank; a plurality of dish containers disposed vertically in the cleaning tank; cleaning means having a plurality of jetting openings for jetting cleaning water. The cleaning means comprises: a first arm nozzle disposed in a space below an upper dish container and rotating substantially horizontally; a second arm nozzle disposed in a space below a lower dish container and rotating substantially horizontally; and a third arm nozzle having a rotation axis eccentric in a predetermined distance from the rotation axis of the second arm nozzle and rotating on the second arm nozzle. The first arm nozzle jets cleaning water toward the upper dish container. The second and third arm nozzles jet cleaning water toward the lower dish container. The third arm nozzle eccentric from the rotation axis of the second arm nozzle jets cleaning water in a wide angle.

Abstract: A dishwasher has a cleaning tank, a plurality of dish containers disposed vertically in the cleaning tank, and cleaning nozzles defining a plurality of jetting openings for jetting cleaning water. The cleaning nozzles include an upper arm nozzle disposed in a space below an upper dish container and rotating substantially horizontal, a first arm nozzle disposed in a space below a lower dish container and rotating substantially horizontal, and a second arm nozzle having a rotational axis spaced a predetermined distance from the rotational axis of the first arm nozzle and rotating on the first arm nozzle. The upper arm nozzle jets cleaning water toward the upper dish container. The first and second arm nozzles jet cleaning water toward the lower dish container. The second arm nozzle eccentric to the rotational axis of the first arm nozzle jets cleaning water over a wide angle.
