Definitions
- the invention relates to a method for operating a dishwasher with at least one washing container, in which, by means of a circulating pump, a washing liquid is conveyed to at least one spray device for acting on items to be cleaned stored in the washing container, and with at least one of the sub-program steps of pre-washing, cleaning, intermediate washing , Rinsing and drying composable washing program.
- the invention also relates to a dishwasher in which a method with a variable washing program is provided for use.
- Dishwashers generally have at least one washing container and spray devices arranged therein, the spray devices being charged with the liquid conveyed by a circulating pump in order to apply washing liquid to the washware stored in the washing container.
- washing programs can usually be selected via a program control device, which can be assembled from the sub-program steps of pre-washing, cleaning, intermediate rinsing, rinsing and drying. Since the washing liquid accumulates with washing residues during the washing phases, filter systems are provided in the water circuit of the dishwasher, through which the washing water circulated by the circulating pump is constantly led.
- the known dishwashers have the disadvantage that the water jet acting on the washware through the spraying devices is relatively strong, and thus the food residues are detached relatively quickly, particularly during the pre-wash phase.
- the object of the present invention is therefore to provide a method with which it is possible to operate a dishwasher with a variable washing program in such a way that the occurrence of washing residues in the washing liquid is less concentrated or spread over a longer period of time so as not to overload the filter systems in the dishwasher.
- a method for operating a Ge dishwasher with at least one washing container in which a washing liquid is conveyed to at least one spray device for acting on items to be cleaned stored in the washing container, and with at least one, by means of a circulating pump the sub-program steps pre-rinsing, cleaning, intermediate rinsing, rinsing and drying composable rinsing program, the pressure with which the rinsing liquid is conveyed from the circulating pump to the at least one spraying device can be varied in order to remove food residues by predetermined hydraulic removal rate, e.g. B. spray pressure and spray quantity to be removed in small quantities and discharged from the dishwasher, which ensures the filter function in the rest of the washing program
- predetermined hydraulic removal rate e.g. B. spray pressure and spray quantity to be removed in small quantities and discharged from the dishwasher
- the method according to the invention makes it possible, for example, during the pre-rinse phase or at the beginning of the main cleaning phase, in which the occurrence of detergent residues detached from the wash ware is particularly high, to reduce the intensity of the water jet acting on the wash ware by the spraying devices. In this way, the detachment of the food residues can be spread over a longer period of time, especially during the pre-rinse phase.
- This has the advantage that peak amounts of washing residues in the washing liquid are reduced or flattened, so that the filter systems in the dishwasher are not overloaded and the cleaning effects are sufficient to maintain the functioning of the filter systems.
- the number of revolutions and thus also the output of the circulating pump for conveying rinsing fluid variable.
- the electric circulation pump is supplied, for example, with a drive current of different power, so that the circulation pump generates correspondingly different numbers of revolutions.
- the circulating pump conveys different amounts of rinsing liquid to the spray device and thus the intensity of the water jet acting on the washware through the spray devices can be varied.
- the circulation pump can be operated at a low number of revolutions, so that the water jet acting on the items to be washed by the spray device is less intensive.
- the detachment of the food residues from the items to be washed is distributed over a relatively long period of time, particularly during the pre-wash phase, since peak amounts of washing residues in the washing liquid are reduced or flattened, so that the filter systems in the dishwasher are not overloaded.
- the generation of a water jet with a lower intensity on the wash ware can also be desirable during the rinse cycle, since the wash ware is only to be wetted with rinse aid.
- a similar effect can be achieved if the circulation pump is operated, at least temporarily, while the washing liquid used for a washing cycle, in particular the pre-washing cycle or the rinsing cycle, is being introduced into the dishwasher. While the washing liquid is being introduced into the dishwasher, the washing liquid required for a wash cycle has not yet been completely introduced into the dishwasher, which means that the liquid level of the washing liquid is still at a low level. As a result, the circulation pump also partially draws in air in addition to the rinsing liquid while the washing liquid is being introduced into the dishwasher and consequently delivers a smaller volume of washing liquid than if the liquid level of the washing liquid in the dishwasher is at a higher or maximum level.
- the reduced delivery capacity of the circulation pump in turn has the consequence that the water jet acting on the wash items through the spray devices is less intensive and the detachment of the food residues from the wash items is distributed over a longer period of time, as a result of which peak amounts of washing residues in the washing liquid are reduced or flattened.
- a method can be provided in which the process for a rinse cycle, in particular
- the amount of washing liquid introduced into the dishwasher in the pre-rinse or rinse cycle corresponds only to part of the total rinse liquid that can be absorbed by the dishwasher.
- the rinsing liquid required for a rinse cycle is not completely introduced into the dishwasher, which means that the liquid level of the rinsing liquid in the dishwasher is at a low level during the entire relevant rinse cycle.
- the circulation pump also partially draws in air in addition to the rinsing liquid during the entire wash cycle and consequently conveys a smaller volume of rinsing liquid than if the liquid level of the rinsing liquid in the dishwasher is at a higher or maximum level.
- the circulation pump can be operated with a lower delivery rate, in particular in the pre-rinse cycle or in the rinse cycle, as a result of which the effects described above can be achieved.
- This mode of operation in which the circulation pump also partially draws in air in addition to the rinsing liquid, can also result in an impulsive course of the water jet or water pressure generated by the circulation pump and the spraying device, which likewise leads to the desired effect that the water jet acting on the wash ware is less intensive and the detachment of the food residues from the items to be washed is spread over a longer period of time, as a result of which peak amounts of washing residues in the washing liquid are reduced or flattened.
- the amount of rinsing liquid used for a rinse cycle is varied during the relevant rinse cycle. Due to the above-described effect that the circulation pump also partially draws in air in addition to the rinsing liquid when the washing liquid is low in the dishwasher and consequently conveys a smaller volume of washing liquid, the delivery rate of the circulation pump can be easily varied by varying the washing liquid level in the dishwasher and thus the intensity of the water jet generated by the circulation pump via the spray devices can be changed.
- the washing-up liquid level in the dishwasher can be varied, for example, by supplying fresh water, which causes an increase in the washing-liquid level.
- a drain pump is preferably used to pump out washing liquid from the dishes. Dishwasher operated at least temporarily during a wash cycle, especially during the pre-wash cycle.
- the drain pump and the circulation pump are operated alternately one after the other. This is preferably done in the end region of the washing-up liquid being pumped out of the washing-up tank by the drain pump, a small amount of washing-up liquid still being present. This allows the sieves in the area of the sump to be cleaned and food residues to be removed from the washing container.
- peak amounts of rinsing residues in the rinsing liquid can be processed particularly well by the dishwasher without impairing the cleaning action if they are in a dishwasher for a rinse cycle, in particular the pre-rinse cycle or the rinse cycle in a first section of the relevant rinse cycle the amount of washing liquid present corresponds approximately to between 30% and 60% of the total washing liquid that can be taken up by the dishwasher, in a second section of the relevant washing cycle the amount of washing liquid contained in the dishwasher corresponds to approximately between 50% and 100% of the total washing liquid that can be taken up by the dishwasher and in a third section of the relevant washing cycle, the amount of rinsing liquid in the dishwasher is approximately between 30% and 60% of the total amount of rinse that can be taken up by the dishwasher fluid corresponds.
- an essentially complete rinsing liquid change is carried out after each partial program step with the use of rinsing liquid.
- a particularly good washing result can be achieved if the washing liquid used for a washing cycle, in particular the pre-washing cycle, is preferably completely replaced at least once during the washing cycle.
- Figure 1 is a diagram showing the operation of the circulation pump and the occurrence of washing residues in the washing liquid in a washing program of a dishwasher according to the prior art
- Figure 2 is a diagram showing the operation of the circulation pump and the occurrence of rinsing residues in the rinsing liquid in a method for Operating a dishwasher according to the present invention according to a preferred embodiment
- FIG. 1 shows a diagram to illustrate the operation of the circulation pump and the occurrence of washing residues in the washing liquid in a washing program S of a dishwasher according to the prior art.
- the time t is plotted on the X axis and the intensity of the occurrence of rinsing residues in the rinsing liquid from 0% to 100% on the Y axis.
- the diagram contains a curve U to represent the operation or the performance of the circulation pump in a washing program of a dishwasher according to the prior art.
- the percentages plotted on the Y axis do not relate to the performance of the circulation pump, but only to the intensity of flushing residues in the flushing liquid.
- the method or washing program S for operating a dishwasher is composed of several partial program steps: pre-washing 1, cleaning 2, intermediate rinsing 3, rinsing 4 and drying 5.
- the dishwasher has a circulation pump, which promotes a rinsing liquid to a spray device for acting on items to be washed stored in the rinsing container and to be cleaned.
- the circulating pump according to the prior art is always operated with full or at least the same power U.
- the known dishwashers have the disadvantage that the action of the water jet acting on the items to be washed by the spray device takes place with maximum strength, and thus the detachment of the food residues is relatively intensive, particularly during the pre-wash phase.
- This can be seen in FIG. 1 by the very steeply falling curve R, which begins at 100%, which represents the intensity of the occurrence of washing residues in the washing liquid.
- R the very steeply falling curve
- up to 80% of the total rinsing residue can occur during the pre-rinsing phase alone, and there is a risk, particularly at the beginning of the pre-rinsing phase, that the rinsing residues cannot be removed in time or to the required extent.
- FIG. 2 shows a diagram to illustrate the operation of the circulation pump and the occurrence of washing residues in the washing liquid in a washing program E according to a preferred embodiment of the method for operating a dishwasher according to the present invention.
- the time t is plotted on the X axis and the intensity of the occurrence of rinsing residues in the rinsing liquid from 0% to 100% on the Y axis.
- the diagram in FIG. 2 also contains a curve U for representing 2 the operation or the output of the circulation pump in a washing program E of a dishwasher according to a preferred embodiment of the present invention.
- the percentages plotted on the Y axis do not relate to the performance of the circulation pump, but only to the intensity of the amount of rinsing residues in the rinsing liquid.
- the method for operating a dishwasher begins with the sub-program steps pre-rinse 1 and cleaning 2; further sub-program steps, e.g. Intermediate rinsing 3, rinsing 4 and drying 5 can follow.
- the dishwasher has a circulating pump which conveys the rinsing liquid to a spray device in order to apply rinsing liquid to the items to be washed stored in the washing container and to be cleaned.
- the circulation pump is operated with variable power U.
- the circulation pump is operated with less than the maximum output, in particular at the beginning of the pre-rinsing phase 1.
- the circulation pump is operated in a first section of the pre-washing phase 1 with approximately 50% of the maximum output, in a second section of the pre-washing phase 1 with approximately 100% of the maximum output and in a third Part of the pre-rinse phase 1 operated again with about 50% of the maximum power.
- This mode of operation of the circulating pump has the result that the washing residues are gradually removed from the items to be washed and thus peak amounts of washing residues in the washing liquid are reduced or flattened.
- the method according to the invention for operating dishwashers thus has the advantage that the action of the water jet acting on the items to be washed by the spray device is not always at maximum, but with reduced and variable strength.
- This can be seen in Figure 2 on the flatter than in Figure 1 recognize sloping curve R, which represents the intensity of the occurrence of 2 rinsing residues in the rinsing liquid.
- This has the advantage that peak amounts of rinsing residues in the rinsing liquid, especially during the pre-rinsing phase, are stretched over a longer period of time, so that the filter systems in the dishwasher are not overloaded and the cleaning effects are sufficient to maintain the functioning of the filter systems.
