  • the dishwasher 1 may be equipped with a water hardness sensor (not shown).
  • the water hardness sensor may be configured to detect a water hardness of the water supplied to the dishwasher 1.
  • the water hardness corresponds, for example, to a concentration of alkaline earth ions in the water.
  • the dishwasher 1 may have a flow sensor (not shown).
  • the flow sensor may be configured to detect a volume of the water supplied to the dishwasher 1.
  • a determination unit can be set up to determine, depending on the volume and the water hardness of the supplied water, the amount of the softening component EK that is required to reduce the water hardness of the volume to a predefinable value. This includes in particular the case that the water hardness of the supplied water is so low that no softener component EK is needed. Thus, the certain amount of softener component EK would be zero and no softener component EK would be added.
  • FIG. 4 shows a detailed view of an embodiment of a metering device 100 with three metering units 1 10, 120, 130.
  • three metering units 1 10, 120, 130 are shown, wherein a first metering unit 1 10 for receiving a supply of a Detergent component RK is set up, a second metering unit 120 is adapted to receive a supply amount softener component EK and a third metering unit 130 is adapted to receive a supply amount of a rinse aid component KK.
  • the metering units 1 10, 120, 130 are each completely filled with their associated dishwashing detergent component.
  • the filling with the supply quantity makes it possible, in particular, to use a dishwasher 1 equipped with the dosing device 100 for a plurality of rinsing operations, without one of the dishwashing detergent components must be refilled.
  • a flushing process is, for example, the course of a wash program.
  • the plurality of rinsing operations is at least 15 rinses, preferably at least 25 rinses.
  • the stock quantity of a dishwashing detergent component is used up, while the stock quantities of the further dishwashing detergent components still have a residual stock which is sufficient for further rinsing operations. Then it may be provided that only the stock quantity of a dishwashing detergent component is filled. Alternatively, it may be provided that at least one additional or even all stocks of the various dishwashing detergent components are filled up.
  • An exemplary composition of the cleaner component is listed in Table 1
  • an exemplary composition of a softener component is listed in Table 2
  • an exemplary composition of a liquid rinse aid component is listed in Table 3.
  • the percentages given in the tables are to be understood as exemplary.
  • further substances can be provided which can be used additionally or alternatively to the specified substances.
  • Table 1 Exemplary composition of a cleaner component. The stated percentages are approximate.
  • Table 2 Exemplary composition of a softener component. The stated percentages are approximate.
  • Substance Function Proportion of anhydrous sodium citrate Builder and buffer 35% ⁇ 5%
  • FIG. 5 shows in three diagrams an example of a time sequence of a washing program of a dishwasher 1 with a dosing device 100.
  • the three diagrams are shown above one another and have a common time axis, which is denoted by t.
  • the upper diagram shows a temperature profile T of the rinsing liquor.
  • the vertical axis corresponds to the temperature, whereby no absolute values are given.
  • a temperature range covered by the axis may include, for example, 10 ° C-80 ° C.
  • the middle diagram shows the course of a volume of water supplied by the dishwasher 1 AQI and pumped volume of the rinsing AQO.
  • the vertical axis corresponds to the volume.
  • the lower diagram shows the course of the amount of the added dishwashing detergent component, the dishwashing detergent in the example having a cleaner component RK, a softener component EK and a rinse aid component KK.
  • the rinse program illustrated in FIG. 5 includes, for example, a pre-rinse cycle, a main rinse cycle, and a rinse cycle.
  • the pre-rinse cycle begins at a time t0 and ends at a time t1.
  • the main rinse cycle begins at time t1 and ends at time t3.
  • the rinse cycle begins at time t3 and ends at time t5.
  • the entire wash program thus begins at time t0 and ends at time t5.
  • water is supplied to the dishwasher 1.
  • a designated water hardness sensor detects the water hardness of the water. Furthermore, the volume supplied is recorded.
  • a quantity of softener component EK is metered in by a metering unit, for example the second metering unit 120 from the example of FIG. 1, of a metering device 100 having at least three metering units. Therefore, the time tO corresponds to a softener dosing time tEK.
  • the temperature T of the rinse liquor during this pre-rinse cycle corresponds to the temperature of the water supplied.
  • the pre-rinse cycle ends and the main rinse cycle begins.
  • Part of the rinsing liquor is pumped out.
  • further water is supplied and a heating device set up for this purpose starts to heat up the rinsing liquor.
  • a further amount of the softener component EK is metered in and an amount of the cleaner component RK is added. Therefore, the time t1 also corresponds to a further softener dosing time tEK and a detergent dosing time tRK.
  • the heating of the wash liquor takes a certain period of time, which is represented by a curved curve. Once a predetermined, for example, by the wash program temperature is reached, the heater stops heating the wash liquor. Then the temperature T starts slowly to sink again.
  • the time t2 also corresponds to a further detergent dosing time tRK.
  • the main rinse cycle ends and the rinse cycle begins.
  • Part of the rinsing liquor is pumped off and further water is supplied. This has the consequence that the temperature of the rinse liquor initially decreases rapidly.
  • the heater heats the wash liquor again to a predetermined temperature.
  • a third amount of the softener component EK and an amount of the rinse aid component KK are added. Therefore, the time t3 also corresponds to a further softener dosing time tEK and a rinse aid dosing time tKK.
