Abstract

Die Erfindung betrifft ein Verfahren zur Erkennung der Beladung eines Siebsystems einer Geschirrspülmaschine, die einen Umwälzkreis mit einem Siebsystem und eine Umwälzpumpe zum Umwälzen der Spülflüssigkeit umfasst, bei dem aus wenigstens einem, einem Niveau der Spülflüssigkeit zugeordneten ersten Wert einer Prozessgröße und wenigsten einem, einem Niveau der Spülflüssigkeit zugeordneten zweiten Wert der Prozessgröße oder aus wenigstens einem, einem ersten Wert einer Prozessgröße entsprechenden ersten Niveau der Spülflüssigkeit und/oder wenigsten einem, einem zweiten Wert der Prozessgröße entsprechenden zweiten Niveau der Spülflüssigkeit wenigstens ein Beladungskennwert ermittelt und als Maß für die Siebbeladung herangezogen wird. Die Prozessgröße steht dabei in eindeutigem Zusammenhang mit der Drehzahl der Umwälzpumpe, ist insbesondere eine Umwälzpumpendrehzahl, ein Umwälzpumpenförderdruck, eine elektrische Förderleistung der Umwälzpumpe, eine mechanischen Förderleistung der Umwälzpumpe, ein Volumen der Spülflüssigkeit oder ein Volumenstrom der Spülflüssigkeit oder eine Strömungsgeschwindigkeit der Spülflüssigkeit.

The invention relates to a method for detecting the loading of a sieve system of a dishwasher comprising a circulation circuit with a sieve system and a circulating pump for circulating the rinsing liquid, wherein at least one, a level of the rinsing liquid associated first value of a process variable and at least one, a level The second value of the process variable assigned to the rinsing liquid or at least one first level of the rinsing liquid corresponding to a first value of a process variable and / or at least one second level of the rinsing liquid corresponding to a second value of the process variable determines at least one loading characteristic value and is used as a measure of the sieve load , The process variable stands in clear connection with the rotational speed of the circulation pump, in particular a circulation pump speed, a circulation pump delivery pressure, an electrical delivery capacity of the circulation pump, a mechanical delivery rate of the circulation pump, a volume of the rinsing liquid or a volume flow of the rinsing liquid or a flow rate of the rinsing liquid.
