Abstract (en)
[origin: US2002117187A1] The invention relates to a commercial dishwashing machine, where the detergent added to the first wash tank of the wash section is controlled by a regulator which controls a dosing device. The regulator is a fuzzy regulator, which in a learning phase determines characteristic influencing values of the system to be regulated. In the learning phase, detergent is continuously added to the first wash tank for a predefined period. The change in the water's conductivity over that period is determined. In the subsequent operating phase, the extent to which the conductivity measured deviates from a set value is determined. Dosing takes place by fuzzy regulation on the set value deviation, on the basis of the measured influencing values as fuzzy variables. Because in the learning phase all the influencing values of the dishwashing machine, dosage device and detergent are taken into account, dosing is automatically optimally adjusted to prevailing conditions.
