Abstract:
A dishwasher comprisinga rotary nozzle having at least two hollow rotatable links, each link including at least one fluid port for receiving pressurized fluid and distributing the fluid in a chaotic trajectory;a fluid inlet port;a nozzle drive pump coupled between the fluid inlet port and the fluid port of each link for supplying the pressurizing fluid to the ports;a pressure control circuit coupled to the nozzle drive pump for controlling pressure of the nozzle drive pump;a sensor at each link for detecting angular positions between the link and the sensor as the link rotates;a chaos calculating circuit coupled between each sensor and the pressure control circuit for (a) determining if the chaotic trajectory is present in response to the angular positions detected by each sensor and (b) adjusting the pressure control circuit if the chaotic trajectory is not present to maintain distributing the fluid in the chaotic trajectory.
