Abstract (en)
A washing machine is described, particularly a laundry washing machine of the domestic type, comprising a system for controlling the detergent consumption. The main feature of the described laundry washing machine is that it comprises means for detecting the detergent concentration in the washing liquid, means for estimating its optimal concentration and means for signalling the user with the result of the comparison between the detected detergent concentration and the optimal one, in order to educate him, wash after wash, in a more correct use of the detergent, so as to avoid useless waste and to reduce as far as possible the negative effects on the environment.
