Abstract
A rotary nozzle device is described. The device includes plural rotatable hollow links which are mutually passable through, a pump for feeding a pressurized fluid into the hollow links, and at least one fluid injection port in at least one hollow link of the nozzle. Moreover, the fluid is injected from the injection port while the hollow link is rotated by the force of the fluid pressurized by the pump, and the motion of the injection port is set in chaotic state by adjusting a structural characteristic of the nozzle.
Claims7
A dishwasher comprising
- a 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.
In a dishwasher having a rotary nozzle including at least two hollow links, each link rotatable about a center and having at least one fluid port for receiving fluid and distributing the fluid, the method comprising the steps of:
- (a) supplying pressurized fluid to the fluid ports;
- (b) distributing the pressurized fluid from the ports into the dishwasher in a chaotic trajectory;
- (c) controlling pressure in step (a);
- (d) detecting at each link the angular position of the link with respect to its respective center as the link rotates;
- (e) calculating if the chaotic trajectory is present in response to step (d);
- and
- (f) if step (e) calculates that the chaotic trajectory is not present, adjusting the control of the pressure in step (c) to maintain the chaotic trajectory of step (b).
