  • some predetermined rinses with predetermined sets of desired operating parameters are preprogrammed in a control device and selectable by the user.
  • the nominal operating parameter sets are designed for a specific standard load of items to be washed. For this purpose, a certain removal rate is provided.
  • More comfortable dishwashing machines comprise devices for determining the loading and for determining and setting load-dependent sets of desired operating parameters corresponding to a load-dependent removal rate, in order, for. B. to save time and energy at low load.
  • the removal rate (AE) provided for rinsing during a rinse cycle is a measure of the cleaning effect.

  • the filling quantity it is not necessary to calculate the filling quantity accurately, e.g. to dose or regulate to 3.5 ⁇ 0.1 liters. Instead, first the recessed actual filling quantity is measured, which is less technically complicated, and in step (b) determines the filling quantity deviation. Then, depending on the filling quantity deviation, a different operating parameter, different from the filling quantity, is determined and adapted such that, in spite of or with the actual filling quantity deviating from the nominal filling quantity, the removal rate and thus the desired cleaning performance are achieved.

  • the delivery rate of the circulating means is normally directly proportional to the speed of the circulating pump. Underfilling must reduce the flow rate or speed to prevent the circulation pump from "draining" and sucking in air due to the lower water pressure at its suction side, resulting in increased noise, speed fluctuations, and reduced flow rate Overfilling the increased water pressure on the suction side of the circulating pump exploited by the fact that the flow rate and the speed increases while the time is shortened, for example, at the same removal rate.

  • the circulation time (T) can be adjusted accordingly.
  • the regulation of the circulation time can be advantageously combined with the control of the flow rate or speed of the circulating means. Because in the case of an underfilling, the reduction of the delivery rate or the rotational speed, which corresponds to a reduction of the volume flow (dV / dt) and the pressure (p) in equation (AE), is compensated by an extension of the circulation time t, so that the removal rate decreases Equation (AE) remains constant. The energy consumption of the longer circulation time is compensated by the energy saving due to the smaller capacity.
  • the deviation (.DELTA.T) can be determined so that the relative deviation (.DELTA.T / T so n) of the circulation time with respect to the target circulation time (T soN ) equal to the relative deviation (.DELTA.V / V SO ⁇ ) of the fill in Reference to the desired filling quantity (V so n) is.

  • step (c) may comprise the following substeps:

  • the target speed (n S ⁇ ⁇ ) is a speed which is smaller than an operating point of the circulating means corresponding speed. Accordingly, the target circulation time (T so n) is a circulation time which is greater than a circulation time corresponding to the predetermined removal rate.
  • the circulation means can then be operated with a larger flow rate per unit of time, that is, at a higher speed (s). This is accompanied by an increase in the pressure (p) in the recirculation means and an increased energy consumption due to the larger filling quantity as well as an increase in the removal rate (see equation AE). The increased energy consumption and the increased removal rate are partially compensated by a corresponding shortening of the circulation time (t).
