Abstract (en)
[origin: EP2561790A1] The water-softening device for electrical household appliances comprises: a first tank (24) for containing substances with water-softening properties, having at least one inlet opening (26) for water to be softened and an outlet opening (28) for softened water; a second salt-containing tank (30), having at least one water inlet opening (32) and an outlet opening (34) for a regenerating brine formed following the dissolution of the salt in the water; a line (36) connecting the second tank (30) to the first tank (24) so that the brine formed in the second tank (30) can flow out towards the first tank (24); a water supply line (10) having a branch-off point (18) into a first branch (20) supplying the first tank (24) and into a second branch (22) which leads to the inlet opening (32) of the second tank (30); and a switching valve (38) with a shutter adapted to cause the water to flow into the first or second branch (20, 22). The valve (38) further comprises a passage (42) which puts into communication the water supply line (10) and the first branch (20) independently of the position of the shutter.
