Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben eines elektrischen Schalters (2), insbesondere eines Relais, in einem Haushaltsgerät (1). Der Schalter (2) umfasst ein bewegliches Element (3) und einen Elektromagneten (5) zum Bewegen des beweglichen Elements (3) aus einer ersten Stellung in eine zweite Stellung. Es wird eine elektrische Spannung (UR) an eine Spule (6) des Elektromagneten (5) angelegt, und hierdurch wird das bewegliche Element (3) aus der ersten Stellung in die zweite Stellung bewegt. Dann wird ein Mittelwert der elektrischen Spannung (UR) auf einen Wert größer als Null reduziert, bei welchem das bewegliche Element (3) in der zweiten Stellung verbleibt. Es wird eine Temperatur (T) einer Umgebung des Schalters (2) gemessen, und in der zweiten Stellung des beweglichen Elements (3) wird der Mittelwert der elektrischen Spannung (UR) in Abhängigkeit von der Temperatur (T) derart eingestellt, dass der Mittelwert bei einer höheren Temperatur (T) größer als bei einer geringeren Temperatur (T) ist. Die Erfindung betrifft auch ein Haushaltsgerät (1).

The invention relates to a method for operating an electrical switch (2), in particular a relay, in a household appliance (1). The switch (2) comprises a movable element (3) and an electromagnet (5) for moving the movable element (3) from a first position to a second position. An electric voltage (U R ) is applied to a coil (6) of the electromagnet (5), and thereby the movable member (3) is moved from the first position to the second position. Then, an average value of the electric voltage (U R ) is reduced to a value greater than zero, at which the movable element (3) remains in the second position. A temperature (T) of an environment of the switch (2) is measured, and in the second position of the movable element (3), the mean value of the electrical voltage (U R ) is adjusted as a function of the temperature (T) such that the Mean value at a higher temperature (T) is greater than at a lower temperature (T). The invention also relates to a household appliance (1).
