Abstract (en)
Water supply and treatment system (2) for household appliances (1), comprising: a backflow prevention device (3), of the type with outlet at atmospheric pressure, comprising an outlet (32); a first tank (5) defining a first volume (V1) containing a decalcifying substance in the form of granules.The water supply and treatment system (2) is designed to operate at atmospheric pressure.The water supply and treatment system (2) comprises an element (32A), wherein a part of said element (32A) being adapted to receive the water exiting through said outlet (32) of the backflow prevention device (3) and being under atmospheric pressure, having a hydraulic head with respect to an outlet (52) of the first tank (5) towards a wash chamber (12) of the household appliance (1) such as to allow the passage of a water flow into said first tank (5).The ratio between a volume of the decalcifying substance (V2) and the volume (V1) of the first tank (5), adapted to contain said volume (V2) of decalcifying substance, is such as to: allow the decalcifying substance to move in different operating configurations of the water supply and treatment system (2); and prevent said granules from getting compacted during the life of the system.
