CROSS-REFERENCE OF RELATED APPLICATIONS[0001]This application is a Divisional, under 35 U.S.C. §121, of U.S. application Ser. No. 12 / 311,093, filed Jan. 6, 2012, which is a U.S. national stage application under 35U.S.C. §371 of PCT / EP2007 / 058994 filed Aug. 29, 2007, which designated the United States; this application also claims the priority, under 35 U.S.C. §119, of German Patent Application No. 10 2006 043 916.3 filed Sep. 19, 2006.BACKGROUND OF THE INVENTION[0002]The invention relates to a water-conducting domestic appliance.[0003]The majority of water-conducting domestic appliances currently in use, such as domestic dishwashers, have an adding device for receiving one or more detergent(s) which are added to the washing water during the course of a washing cycle to clean the items for washing that are shelved in the dishwasher. All of the detergent held in the adding device is conventionally dispensed into the washing compartment during the washing cycle and mixed into the washi...

AI Technical Summary

Benefits of technology

Ensures long-term stability of detergents, prevents wastage, and supports complex washing cycles by providing precise detergent dosing and temperature control, enhancing cleaning effectiveness while reducing environmental impact.

Problems solved by technology

This operation is not convenient for the user of the dishwasher.

Furthermore, with dishwashers of this kind there is the problem of the quantity of detergents poured into the adding device potentially varying from user to user and also from washing cycle to washing cycle.

An incorrectly dosed quantity of detergent can lead to unsatisfactory wash results on the one hand—if an inadequate dose of detergents has been added, and lead to wasting of detergents, and environmental pollution therefore, on the other hand—if an excessive quantity of detergents has been added.

Moreover, adding devices, which add the quantity of detergents stored therein to the washing water in one go, do not allow more complex washing programs to be carried out.

Thus for example in certain situations it may be expedient to add the detergent to the washing water at different times. Adding devices, which are designed to receive a single detergent dose, cannot support such complex washing cycles.

Holding a quantity of detergent which is larger than the quantity required for a washing cycle entails the problem of the portion of detergent not added to the washing water being exposed to high temperatures and high differences in temperature with each washing cycle.
