Washing machine detergent feed

摘要

The invention relates to a method for controlling the dosing of detergent in multiple stage washing machines having at least one separate detergent tank per washing stage. The entry of water into a detergent tank of the washing machine releases, without intervention in the washing machine control system, the single dosing of a predetermined amount of detergent into this detergent tank, the release of further dosages being prevented until a renewed activation. Furthermore, the invention relates to a control device for dosing detergents in washing machines (1) in accordance with one of the above methods. In at least one detergent tank (2) of the washing machine (1), a humidity sensor (7) is fitted and linked with a dosing system (10) without connection to the washing machine control system, via a signal line (8). Upon entry of the water (5) into a detergent tank (2) equipped with a humidity sensor (7), a signal is produced which is processed internally in the dosage control system, thus releasing the dosage of a predetermined amount of detergent into this detergent tank (2).
