Definitions
- the invention relates to a reversing device, in particular for a dishwasher with a washing container with a hydraulic arrangement with at least two spray devices which act on the items to be cleaned which are arranged in the washing container by means of a liquid conveyed by a circulating pump, the conveyed liquid flowing through a reversing device, and wherein the reversing device has at least two outputs for supplying the liquid to different spray devices, which can be opened or closed by means of an actuating element such that either one of the outputs or a number of outputs or all outputs alternately in succession and / or continuously are open or closed.
- control element is a rotary valve arranged in a continuous-flow heater, which in the direction of circulation alternately has a closed area after an open area, between which there is an empty space ,
- the aforementioned open area is a circular opening.
- the rotary slide valve from DE-198 57 103-A1 can be controlled, for example, using an actuator device known from DE-10065571.8 (DE-100 65 571-A1), which includes a motor-driven cam disk that is firmly connected to the rotary slide valve.
- the object of the invention is to provide a reversing device in a simple manner with which the possibilities of influencing the course of the cleaning program are improved and thus optimally achieve a cleaning effect in accordance with the degree of soiling of the items to be cleaned.
- This object is achieved in that the characteristic of the hydraulic arrangement and the characteristic of the circulation pump are changed simultaneously or alternately.
- a combination of the influencing of the characteristics on the one hand of the hydraulic arrangement and on the other hand of the circulation pump results in a much greater variability in the program control, e.g. a dishwasher, and thus much greater possible variations in the loading of the items to be cleaned, with which a reversing device was created in a simple manner with which the possibilities of influencing the course of the cleaning program are improved and thus a cleaning effect in accordance with the degree of soiling of the items to be cleaned optimally achieved.
- the characteristic of the hydraulic arrangement is changed by changing the flow of the liquid through the reversing device and the characteristic of the circulating pump by regulating the rotational speed of the circulating pump, with which the combination according to the invention of influencing the characteristic on the one hand of the hydraulic arrangement and on the other hand the circulation pump has succeeded in a simple way.
- the adjusting element of the hydraulic arrangement has at least one opening with different cross sections compared to at least one further opening. Through at least one smaller opening, it is possible to convey a smaller amount of liquid to a desired spray device, thus creating the simplest possible way of influencing the characteristics of the hydraulic arrangement.
- the at least one opening with different cross sections advantageously has a substantially smaller cross section than the at least one further opening, which further simplifies the possibility of influencing the characteristics of the hydraulic arrangement.
- the opening with the substantially smaller cross-section than the at least one further opening for supplying the liquid to an upper spraying device is used so that it can be operated with the amount of liquid available for circulation without running dry. Due to the opening associated with the supply of the liquid to an upper spray device with the substantially smaller cross-section compared to the at least one further opening, the amount of liquid - the so-called dead water amount - due to the longer supply of the liquid to the upper spray device is reduced ,
- the actuating element is preferably a disk which has at least one opening with the substantially smaller cross section than the at least one further opening.
- the design of the control element as a disk is the simplest way of implementing the hydraulic arrangement of the reversing device according to the invention.
- the at least one larger opening expediently serves essentially to supply the liquid to a lower spray device, but alternatively it can also serve to supply the liquid to the upper spray device.
- the opening associated with the supply of the liquid to a lower spray device with the substantially larger cross-section compared to the at least one smaller opening makes it possible in a simple manner to deliver significantly larger amounts of cleaning liquid.
- the possibility of delivering substantially larger amounts of cleaning fluid to the upper spray device is also created in a simple manner.
- two larger openings on the disc opposite one another are preferably used for simultaneously supplying the liquid to a lower and an upper spray device.
- the variability in the washing program control is increased by the use of differently large quantities of liquid for the different operations of the spray device - only upper spray device - only lower spray device - both spray devices.
- closed areas of the actuating element which lie in the closed positions in a sealing manner at the corresponding exits, each have a circumferential sealing edge which protrudes in the direction of the exits.
- the smaller opening is also surrounded by a sealing edge which rises in the direction of the exits. This measure ensures a complete sealing system at the corresponding outputs in a simple manner.
- the speed of the circulating pump is reduced or increased in predetermined sub-program sections of the washing program sequence or over the entire washing program sequence, whereby the number of program types can be increased further and a particularly good adaptation of the program course to the types of contamination of the objects to be cleaned, e.g. of the dishes in a dishwasher.
