HOUSEHOLD DEVICE WITH A DRYING FUNCTION AND WITH A DEVICE FOR RECORDING A HUMIDITY LEVEL AND METHOD FOR RECORDING A HUMIDITY LEVEL

摘要

The present invention relates to a domestic appliance (10) having a drying function and to a device for detecting a humidity H of objects (20) which can be arranged in the domestic appliance (10), the household appliance (10) comprising: a container (18) for Receiving the objects to be dried (20), at least one sensor (12) for detecting at least one measuring signal in the form of a light intensity (I, I 02, I 03) reflected by the objects to be dried (20)), and a controller (16) which is connected to the at least one sensor (12) and in which at least one reference characteristic (30) is stored, wherein the sensor (12) is configured to generate a first measurement signal (I) in a water absorption band corresponding to a wavelength range in which water is light absorbed to detect, and to detect at least a second measurement signal in another wavelength range, which has a reflected light intensity (I 0) a and to the controller (16), wherein the controller (16) is configured to determine the humidity (H) of the objects to be dried based on the first and at least one second measurement signals and based on the stored reference characteristic (30) (20) in the container (18). Furthermore, the invention relates to a household appliance (10) with a drying function and with a device for detecting a kind of in the household appliance (10) can be arranged to be dried objects (20) and a method for detecting a humidity and / or detecting a kind of in a household appliance (10) can be arranged to be dried objects.
