  • several wash programs are provided, one of which can be selected and started by the operator. This makes it possible to adjust the course of a wash cycle, in particular to the load, to the type of loading, to the degree of contamination of the items to be washed and / or to the desired duration of the wash cycle, etc .., Adapt.
  • the stored washing programs may preferably be designed such that the respective wash cycle controlled by them in particular at least one pre-rinse for pre-cleaning items, at least one cleaning operation for thoroughly cleaning items, at least one intermediate rinse for removing soiled rinse liquid from the items to be washed, at least one rinse cycle to avoid of stains on the items to be washed and / or for preparing a drying step, and / or at least one drying course for drying the items to be washed.
  • Rinse cycle, cleaning cycle, intermediate rinse cycle and rinse cycle are referred to as water-carrying partial rinses, since during their implementation, the introduced into the rinsing chamber items to be treated with a rinsing liquid. During the drying cycle, a use of rinsing liquid is usually not provided.
  • the treatment of the items to be washed with rinsing liquid takes place in a substantially complete rinsing chamber, in particular a rinsing container, the dishwasher.
  • the flushing chamber is associated with an inlet valve, which allows to fill flushing liquid into the washing chamber.
  • the inlet valve openable and closable by the control device, so as to influence the inflow of Spülflüs- stechnik.
  • a rinsing liquid is understood here to mean, in particular, a liquid which is intended to be applied to the ware in order to clean it and / or to treat it in another way.
  • the rinsing liquid can also be provided for heating the items to be washed, which is customary, for example, during a rinsing step.
  • the rinsing liquid entering the rinsing chamber via the inlet valve is usually fresh water.
  • the rinsing liquid in the rinsing chamber can be enriched with cleaning agents, with cleaning aids, such as, for example, rinse aid and / or with dirt which has been removed from the items to be washed. But there are also cases conceivable in which already enriched water is filled as flushing liquid via the inlet valve in the washing chamber.
  • the rinsing chamber is associated with a circulating pump for circulating the filled rinsing liquid, which makes it possible, the rinsing liquid contained in the rinsing chamber, for. to be removed from a collecting device for rinsing liquid and applied to the dishes by means of a spray system associated with the rinsing chamber.
  • the speed of the circulating pump is variably controllable and / or controllable by the control device of the dishwasher.
  • the dishwasher further comprises a concentricity monitoring unit for performing a concentricity test in the circulation pump.
  • the concentricity monitoring unit may in particular be part of the control device, or be connected to the control device of the dishwasher for data exchange.
  • a circulating pump is generally in the concentricity when sufficient rinsing liquid is present in the collecting device of the rinsing chamber in order to prevent suction of air through the circulating pump. Whether or not air is sucked in a particular case depends, among other things, on the speed of the circulating pump. The reason for this is that with increasing speed the circulating pump is an ever smaller part of the total rinsing liquid present in the rinsing chamber in the collecting device, since it takes a certain amount of time before the rinsing liquid sprayed onto the ware returns to the collecting device. The speed at which a concentricity is just possible is also referred to as the maximum concentricity speed.
  • the dishwashing machine according to the invention is designed so that during the execution of a rinse cycle at least one filling sequence for filling the rinsing chamber is carried out with rinsing liquid, which comprises a filling phase, during which the inlet valve is opened and the circulation pump is turned on.
  • rinsing liquid which comprises a filling phase
  • the inlet valve is opened and the circulation pump is turned on.
  • Such a filling sequence can be provided, for example, at the beginning of one of the water-conducting partial rinses of the rinse cycle, in each case at the beginning of several of the water-carrying Part Touch réelle the rinse cycle or at the beginning of all the water-carrying Part Dahl réelle the rinse cycle.
  • an algorithm ie a sequence procedure or sequence sequence for varying the rotational speed of the circulating pump, is provided for the filling phase, which allows the rotational speed of the circulating pump to be adapted to the amount of flushing liquid increasing during the filling phase, on the one hand, the circulating pump always is operated at a relatively high speed, and that on the other hand, the circulating pump is operated at least for a substantial part of the duration of the filling phase in the concentricity.
  • the cleaning effect is increased during the filling phase by an optimized loading of the items to be washed with rinsing liquid and at the same time lowered the noise level of the dishwasher, since disturbing Schlürfgeakische can be largely avoided when sucking air through the circulation pump.
  • the algorithm or the sequence sequence can be controlled by the control device of the dishwasher.
  • the algorithm for varying the rotational speed comprises a varying step for stepwise variation of the rotational speed by a preset value.
  • the varying step is the actual adjustment of the speed of the circulating pump.
  • the default value may be a summand, so that the speed provided after the varying step results from the sum of the speed provided before the varying step and the default value.
  • the varying step can be carried out, for example, by the control device of the dishwasher.
  • the algorithm comprises at least one test step for performing a concentricity test.
  • the respective test step it can be determined whether or not the circulation pump is in the course of the rotational speed resulting in the previously performed variation step.
  • the respective test step can be carried out in particular by the concentricity monitoring unit.
  • This result can then be used in a subsequent change step to change the default value to adjust the default value so that in a further variation step with the new default value, an optimal adjustment of the speed of the circulation pump to the current amount of flushing liquid can be performed.
  • the result of the checking step can be transmitted from the concentricity monitoring unit to the control device, which can then carry out the modification step.
  • This sequence of steps which includes a varying step, a checking step and a changing step, may be repeated until a sufficient amount of rinsing liquid is filled in the rinsing chamber. In this way, it is possible to operate the circulation pump at a high speed during the entire filling phase, without the risk that the circulation pump is operated permanently out of the concentricity.
  • the algorithm comprises an aborting step for terminating the filling sequence upon reaching a final value provided for the rotational speed and in the case of a preferably circulating pump.
  • the final value can correspond to the speed with which the circulation pump is operated after the filling sequence.
  • the algorithm automatically compensates deviations of the filling flow, ie the inflow quantity of flushing liquid per unit of time, from a nominal filling flow.
  • the filling phase unlike a pure time control of the inlet valve, always continued until an optimized amount of flushing liquid is in the washing chamber.
  • a simple, switchable inlet valve can be used, which can only assume an open position and a closed position, since control or regulation of the filling flow of the rinsing liquid during filling into the rinsing chamber is not required.
  • the control device can also be designed simply, since it is provided only for the output of two control commands to the inlet valve, namely "open valve” and "close valve".
  • the algorithm rules out that in the rinsing chamber too low a level of rinsing liquid results, which is based on the fact that a significant part of the filled rinsing liquid collects in a wrong inserted hollow vessel, for example in a pot with upwardly facing opening. A measurement of the level with a separate level sensor is not required for this purpose.
  • the dishwashing machine according to the invention can consequently be of particularly simple design.
  • the algorithm does not require that the supply valve be temporarily closed during the feed sequence. In this way, the filling sequence can be completed much faster than in such filling method, which basically provide a multi-stage filling.
  • the default value is greater than or equal to zero, if the result of the test step is that the circulating pump is in the concentricity. In this way it can be prevented that the speed is lowered unnecessarily.
  • the results of successive test steps consist in that the circulation pump is in each case in the concentricity, provided an increase in the default value. In this way, it can be effected that the actual speed approaches faster that speed at which a concentricity is just possible.
  • the increase of the default value is omitted when a maximum value provided for the default value is reached.
  • the default value is less than or equal to zero, if the result of the checking step is that the circulating pump is not in the concentricity. This can be effected in a non-circular running of the circulation pump, that the speed is lowered, and so after one or more variation steps a concentricity of the circulation pump is achieved.
  • the results of successive test steps consist in that the circulation pump is not in each case in the concentricity, provided a reduction of the default value. In this way, the concentricity can be achieved faster.
  • the lowering of the default value is omitted if a minimum value provided for the default value is reached.
  • an excessive reduction of the default value can be avoided, which could lead to the rotational speed at which a concentricity is just still possible, is exceeded unduly with continued implementation of the algorithm, which could then lead to a rocking of the algorithm.
  • the default value is set to zero. In this way, a careful approach to that speed is effected when changing from concentricity to a non-circular run or from the non-circular run in the concentricity, in which a concentricity in the particular amount of flushing liquid is just possible. In particular, such an excessive change in the default value and consequently the speed can be avoided, which could lead to a build-up of the algorithm.
  • the inlet valve is opened and the circulating pump is switched off, the duration of the pre-filling phase being dependent on a time value.
  • the duration of the pre-filling phase being dependent on a time value.
  • such a starting value is provided at the beginning of the filling phase for the rotational speed that, in the case of a filling flow of rinsing fluid which is within a standard range, the circulating pump is concentric in the first checking step.
  • a standard range for the filling flow is defined in a dishwasher.
  • an upper limit may be provided for the standard range, which exceeds the Nenneinyogllstrom by a certain percentage, for example 10%.
  • a lower limit may be provided for the standard range, which falls below the Nenneinyogllstrom by a certain percentage, for example, 10%.
  • the starting value for the speed is set so that at a lying in a standard range filling the circulating pump is in the first test step in the concentricity, it is ensured in the practically relevant cases that the speed approaches from below to the optimum value , As a result, at least in the initial phase Schlürfgehoffsche be avoided.
  • the invention corresponds to the beginning of the filling phase of the default value its intended maximum value. In this way, the approach to the optimum value can be accelerated, which is particularly advantageous for a relatively large filling flow.
  • the inlet valve is opened and the circulating pump is switched on, the duration of the refilling phase being dependent on a time value.
  • a defined excess of rinsing liquid can be introduced into the rinsing chamber to ensure a concentricity of the circulating pump, even in unfavorable conditions, for example when the filling tube is rotating or overturning and flushed with rinsing liquid, which thus extracts the rinsing liquid.
  • the circulation pump comprises an electric motor, wherein the concentricity monitoring unit for monitoring Variations of at least one electrical operating parameter of the electric motor is formed. If the amount of rinsing liquid in the rinsing chamber is too low, the circulating pump sucks, as already described, not only rinsing liquid, but also air. The ratio of intake air and sucked rinsing fluid varies by a statistical average. These fluctuations in turn lead to fluctuations in the electrical operating parameter of the circulating pump, so that the evaluation of the fluctuations without detection of the absolute value of the operating parameter allow a statement as to whether the circulating pump is in concentricity or not. As a result, the quality of the concentricity test can be improved.
  • the concentricity monitoring unit can be designed to detect the electrical power of the circulating pump.
  • the concentricity monitoring unit may be designed for this purpose for detecting the electrical current consumption.
  • By an analysis of the detected power can then be determined by the concentricity monitoring unit, whether the circulating pump is in the concentricity or not. It can be concluded in particular in case of deviations of the actual performance of a planned performance and / or strong fluctuations in performance over time that the circulation pump is not in the concentricity.

  • the electromagnets are commutated via a control electronics. Compared to other possible engine concepts, this allows both the direction of rotation and the speed of the engine to be controlled in a simple manner.
  • the motor By operating the motor in exactly one direction of rotation, it is possible to optimize the fluid-carrying parts of the circulation pump. This results in a high flow rate with low energy consumption.
  • the capacity of the circulation pump can be controlled as needed, which further increases energy efficiency.

It can be checked as a termination condition, whether the rotational speed of the circulation pump 22 has reached a final value. If this is true, then it can be concluded that such an amount of rinsing liquid S is filled in the rinsing chamber 7, that in principle in the continuation of the rinse operation of the circulating pump in the concentricity is possible. On the other hand, if the termination conditions do not apply, the modification step VES is carried out, in which the default value for a renewed execution of the variation step VAS is adjusted.
  • the default value is adjusted as a function of the preceding test step PS.
  • the default value is typically increased, whereby the slope of a speed representing curve increases in the next VAS variation step, so that the speed approaches from below the value at the current amount at Rinsing liquid S just a round run is possible. It can be provided for the default value, a maximum value, when it reaches an intended increase does not occur.
  • the default value is typically lowered, and the slope of the curve representing the rotational speed is lowered in the next variation step VAS, so that the rotational speed approaches from above to the value at which in the current amount of flushing liquid S just a round run is possible.
  • a minimum value may be provided for the default value, upon reaching which a reduction which is provided per se is omitted.
  • a timed refilling phase NFP follows, the duration of which depends on a further time value, which may be contained in the washing program called by the operator, for example.
  • the timing value can be set so that during refilling NFP under standard conditions as reserve such an amount of flushing liquid S enters the washing chamber 7, which is for example 10% to 20% of the amount of Vorhellphase VFP.
  • the provision of reserves of rinsing liquid by means of the refill phase NFP is not absolutely necessary, but in many cases makes sense.
  • the inlet valve 18 is then closed in a step ZS and the end EN of the filling sequence F is reached.
  • filling sequence F ensures that at its end EN, the circulation pump 22 can be operated at its final speed in the concentricity.
  • the filling sequence F further allows a sparing use of rinsing liquid S. In this case neither a complex measurement of the filled amount of rinsing liquid S or the filling level of the rinsing liquid S in the rinsing chamber 7 nor a control of the filling of the rinsing liquid S is required.
  • the filling sequence F described ensures that the cleaning effect of a rinse cycle already begins during the filling sequence F.
  • Schlürfge syndrome the circulating pump 22 are minimized because they can be operated to a large extent the duration of the filling sequence F in the concentricity.
  • FIG. 4 1 shows a diagram for explaining filling sequences F, F ', F "of a dishwasher 1 according to the invention, in which the rotational speed of the circulation pump 22 is plotted on the vertical axis U.
  • the filling sequence F comprises a prefilling phase VFP, a filling phase FP and a refill phase NFP
  • the fill sequence F ' comprises a prefill phase VFP', a fill phase FP 'and a refill phase NFP'.
  • the filling sequence F “includes a prefill phase VFP", a fill phase FP "and a refill phase NFP".
  • a curve DZ shows the rotational speed DZ of the circulation pump 22 during the filling sequence F on the assumption that when the inlet valve 18 is open, a filling flow is established which corresponds to the nominal filling flow.
  • a curve RDZ shows that maximum concentric rotational speed RDZ, in which case a concentricity of the circulation pump 22 is just possible in this case.
  • a curve DZ ' shows the rotational speed DZ' of the circulation pump 22 during the filling sequence F ', it being assumed that when the inlet valve 18 is open, a filling flow is established which corresponds to the minimum filling flow of the standard range.
  • a curve RDZ ' shows the maximum rotational speed RDZ' associated therewith.
  • a curve DZ shows "the rotational speed DZ" of the circulation pump 22 during the filling sequence F ", at which a filling flow, which corresponds to the maximum filling flow of the standard range, is established when the inlet valve 18 is open
  • a curve RDZ" shows the corresponding maximum concentric rotational speed RDZ ".
  • the filling sequence F will be explained.
  • the inlet valve 18 is opened so that rinsing liquid S is filled into the rinsing chamber 7.
  • the maximum concentric rotational speed RDZ rises from zero over time.
  • the circulation pump 22 is turned on and initially operated at a speed DZ, which corresponds to a start value SDZ.
  • This speed SDZ lies below the maximum concentric rotation speed RDZ, so that in the context of the basis of the FIG. 3 Algorithm explained the speed DZ with a maximum provided default value, ie with maximum slope, is increased until the first time a non-circular run of the circulation pump is detected.
  • the default value is reduced so long, so the slope of the speed DZ reduced until again concentricity occurs.
  • the default value is then increased until a non-round run is detected again. In this way, it is ensured that the rotational speed DZ is substantially just below the maximum concentric rotational speed RDZ.
  • the filling phase FP is then terminated when the rotational speed DZ reaches a final value EDZ and the circulation pump 22 is thereby concentric. In this way, it is ensured that, at the end of the filling phase FP, there is a quantity of flushing liquid S in the flushing chamber 7, which in principle makes it possible for the circulating pump 22 to run in a concentric manner at its end speed EDZ can be.
  • the following time-controlled refilling phase NFP ensures that an additional amount of rinsing liquid S enters the rinsing chamber, so that a concentricity occurs even when rinsing liquid is withdrawn from the circulation, for example, by rinsing liquid S collects in an overturned hollow vessel to be cleaned.
  • FIG. 5 shows an enlarged section of the filling sequence F of FIG. 4 , wherein in addition the default value VW is shown over time. It can be seen that the speed DZ is adjusted stepwise over time.
  • the default value VW is set so that it corresponds to a predetermined maximum value VWM.
  • the maximum value VWM is selected such that the average gradient of the rotational speed DZ is initially greater than the slope of the maximum rotational rotational speed RDZ.
  • the rotational speed DZ approaches the maximum concentric rotational speed RDZ first and exceeds it, which is detected in a test step PS.
  • the default value VW is set to zero, so that the speed DZ remains unchanged for one pass of the algorithm. Since the maximum concentric rotation speed RDZ continues to increase during this time, in the example of FIG. 5 the circulation pump 22 immediately back into the concentricity. Therefore, the default value VW is increased again.
  • the default value VW is increased up to the maximum value VWM, since in this time window there is always a concentricity, so that the average slope of the speed DZ increases up to its maximum value.
  • a sufficient filling amount is determined by a dynamic speed increase with a concentricity detection.
  • a sufficient filling quantity can be recognized by the fact that the circulation pump continuously touches the boundary of the concentricity. This can, as shown in the figures, be done as follows: After filling a certain minimum amount of water, the pump is started and their speed increased continuously. In this case, the pump power or the pump current is detected. If a scattering or a deviation of the parameters is detected in the pump power or the pump current, the concentricity amount for the amount of water flowed in there is reached and the increase in the pump speed is reduced until the dispersion of the pump power or the pump current again reduces. This should be carried out in such a way that the increase in the pump speed adapts to the incoming water quantity.
  • the sufficient filling quantity can then be determined by means of the pump speed and the filling process can be ended when a predetermined speed is reached.
  • the pump runs mainly in the concentricity mode, whereby the pump noise is reduced compared to the non-run mode.
  • Another advantage is the variable capacity for incorrectly set dishes (eg bowl or pot). If the current bath volume is missing a certain amount of water, this amount is compensated by the run-round algorithm and sufficient water is replenished so that concentricity is guaranteed.
