Abstract

Improved circuit for feeding water to washing machines, mainly dishwashers, comprising a water collection sump, into which a water inlet nozzle penetrates hermetically, which extends upwards and is connected to a decalcification device, being the latter is fed by a tube provided with a conduction switch that communicates with the environment at a level higher than the static level of the water contained in the bucket, said tube extending below the dynamic level of the water in the bucket, said circuit being characterized in that the outlet mouth (8) of the nozzle (7) is located at a level © lower than said static level (A), the end of the nozzle being inserted a certain distance into a bell-shaped element (10), the mouth of which is at a level (D) higher than said dynamic water level (B), delimiting the internal surface of the bell-shaped element and the external surface of the nozzle illa, in the aforementioned strait, a space that has a volume at least equal to the internal volume of the section of the supply tube (5) comprised between the static level of the water (A) and the level © of the mentioned supply or outlet mouth .
