Method for operating a water-conducting household appliance with a spectrometer and suitable household appliance

摘要

The invention relates to a method for operating a water-conducting domestic appliance 10 having a drum 16 for receiving objects 5, 17 to be treated, a control device 18, at least one spectrometer 1, 32, 38, which has at least one radiation source 2, 29, 35, at least one Radiation detector 3, 30, 36 and a microcomputer 4, 31, 37, wherein it comprises the following steps: (b) emitting radiation from the at least one radiation source 2, 29, 35 of the at least one spectrometer 1, 32, 38 in one Wavelength range of λ to λ, so that at least one object 5, 17 is acted upon in the drum 16 with the radiation, and the at least one radiation detector 3, 30, 36, the radiation from the at least one object 5, 17 reflected radiation as a measuring signal and transmitting of the measurement signal registered by the at least one radiation detector 3, 30, 36 to the microcomputer 4, 31, 37; (c) evaluating the measurement signal Step (b) with an evaluation routine stored in the microcomputer 4, 31, 37 with regard to at least one property of the at least one article 5, 17 in the drum 16 and a distance x 6 between the at least one spectrometer 1, 32, 38 and the at least one article 5, 17 in the drum 16 and transmitting the at least one property to the controller 18 when the distance x 6 does not deviate from a predetermined threshold S; and (d) selecting and / or optionally adjusting a treatment by the controller 18 with respect to the at least one property transmitted in step (c), wherein the steps (b) to (d) are performed one or more times. The invention also relates to a suitable for carrying out the method water-conducting household appliance.
