US 7,047,986 B2 · Movement reversal device, particularly for a dishwasher

Abstract

A movement reversal device is used in a dishwasher. The dishwasher has a washing receptacle and a hydraulic assembly provided with at least two spraying devices impinging upon goods to be washed with a fluid transported via a circulating pump. The transported fluid flows through the movement reversal device that contains at least two outlets for feeding different spraying devices. The outlets are opened or closed by a positioning element such that one or several or all outlets are open or closed one after another and/or continuously. In order to better influence the course of the wash cycle and to obtain an optimal washing effect corresponding to the degree of dirtiness of the goods to be washed, the characteristics of the hydraulic assembly and the characteristics of the circulating pump are simultaneously or alternately changed by the movement reversal device.

In combination with a dishwashing machine having a washing receptacle for receiving goods to be washed, a circulating pump for conveying a liquid and a hydraulic configuration with at least two spraying devices, a movement reversal device through which the liquid flows, the movement reversal device comprising:

a movement reversal device body having a positioning element and at least two outlets formed therein for supplying the liquid to different ones of the spraying devices, said two outlets being opened or closed by said positioning element, such that in each case either one of said two outlets or both of said two outlets being opened or closed alternately one after another and/or continuously, and a characteristic of the hydraulic configuration and a characteristic of the circulating pump being altered simultaneously or alternately, wherein the characteristic of the hydraulic configuration is altered by changing a through flow of the liquid through said movement reversal device body and the characteristic of the circulating pump is altered by regulating a speed of the circulating pump.

A dishwashing machine, comprising:

a washing receptacle for receiving goods to be washed;
a circulating pump for conveying a liquid;
a hydraulic configuration with at least two spraying devices;
and
a movement reversal device through which the liquid flows, said movement reversal device fluidically connected to said hydraulic configuration and receiving the liquid from the circulating pump, said movement reversal device having a positioning element and at least two outlets formed therein for supplying the liquid to different ones of said spraying devices, said two outlets being opened or closed by said positioning element, such that in each case either one of said two outlets or both of said outlets being opened or closed alternately one after another and/or continuously, and a characteristic of said hydraulic configuration and a characteristic of said circulating pump being altered simultaneously or alternately, wherein the characteristic of the hydraulic configuration is altered by changing a through flow of the liquid through said movement reversal device body and the characteristic of the circulating pump is altered by regulating a speed of the circulating pump.
