Abstract

The invention relates to a method for operating a water-conducting domestic appliance and to a domestic appliance suitable therefor having a drum (16) for receiving items (5, 17) to be treated, a controller (18), and a spectrometer (1, 32, 38), which comprises a beam source (2, 29, 35), a beam detector (3, 30, 36) and a microcomputer (4, 31, 37), the method comprising the following steps: emittingradiation from the beam source (2, 29, 35) in a wavelength range such that the radiation impinges on at least one item (5, 17) in the drum (16), and the beam detector (3, 30, 36) registers the radiation reflected by the item as a measurement signal that is transmitted to the microcomputer (4, 31, 37); evaluating the measurement signal, by means of an evaluation routine, to find a characteristic of the item (5, 17) in the drum (16) and a distance (x 6) between the spectrometer (1, 32, 38) and the item (5, 17) in the drum, the characteristic being transmitted to the controller (18) if the distance does not deviate from a predefined threshold value (S); and selecting and / or adapting a treatment process using the controller (18) on the basis of the transmitted characteristic, the method stepsbeing carried out once or multiple times.

Description

technical field

[0001] The invention relates to a method for operating a water-conducting domestic appliance with a drum for receiving objects to be treated, a control device and at least one spectrometer comprising at least one radiation source, at least one radiation detector devices and microcomputers. Furthermore, the invention relates to a water-conducting household appliance suitable for carrying out the method. Background technique

[0002] In particular, in order to control the treatment program in a manner that is as optimal as possible and in harmony with the items to be treated in the household appliance, it is important that there are as many facts as possible about the properties of the items to be treated before and during the treatment process. Information is available. To obtain this information, domestic appliances generally have one or more sensors, which can also include spectrometers.

[0003] Thus, against the background mentioned above, household app...
