Abstract

Die Erfindung betrifft eine Vorrichtung und ein Verfahren für ein Haushaltsgerät, insbesondere eine Geschirrspülmaschine, mit einem Feuchtesensor (10, 30) zur Erfassung des Trockengrades innerhalb eines Behälters (1) oder Luftkanals (2) des Haushaltsgerätes. Erfindungsgemäß erfaßt der Feuchtesensor (10, 30) eine an einer Erfassungsfläche (11, 32) im Innern des Behälters (1) oder des Luftkanals (2) anhaftende Feuchtigkeit. Die Feuchtigkeitsbildung auf der Erfassungsfläche ist abhängig von der Luftfeuchtigkeit im Behälter, so daß das Ende einer Trockenphase sicher und berührungslos erfaßbar ist.

Figure imgaf001
The invention relates to a device and a method for a household appliance, in particular a dishwasher, with a humidity sensor (10, 30) for detecting the degree of dryness within a container (1) or air duct (2) of the household appliance. According to the invention, the humidity sensor (10, 30) detects a moisture adhering to a detection surface (11, 32) in the interior of the container (1) or the air channel (2). The formation of moisture on the detection surface is dependent on the humidity in the container, so that the end of a dry phase is detected safely and contactless.
