Abstract

Bei einer Einrichtung zur Zustandserfassung an einer Platte oder einer Wand eines Haushaltgerätes, insbesondere Küchengerätes, soll die Zustandserfassung vereinfacht und verbessert werden. Hierfür überträgt an wenigstens einer ersten Stelle der Platte 12 oder Wand 8 ein Schallwellensender 1 Schallwellen auf die Platte 12 oder die Wand 8. An einer vom Schallwellensender 1 entfernten zweiten Stelle der Platte 12 oder der Wand 8 ist ein Schallwellenempfänger 2 oder ein Schallwellen reflektierendes Element 3 angeordnet, wobei wenigstens ein Parameter der Schallwellen durch den zwischen der ersten Stelle und der zweiten Stelle herrschenden Zustand beeinflusst wird. Eine Auswerteschaltung 4 wertet die zustandsbedingte Beeinflussung der Schallwellen aus.

In a device for condition detection on a plate or a wall of a household appliance, in particular kitchen appliance, the state detection is to be simplified and improved. For this purpose transmits at least a first point of the plate 12 or wall 8, a sound wave transmitter 1 sound waves on the plate 12 or the wall 8. At a remote from the sound wave transmitter 1 second location of the plate 12 or the wall 8 is a sound wave receiver 2 or a sound wave reflecting element 3, wherein at least one parameter of the sound waves is influenced by the state prevailing between the first location and the second location. An evaluation circuit 4 evaluates the conditional influence of the sound waves.
