Abstract

Device for feeding water into a washer machine, in particular a dishwasher equipped with an anti-calcium unit (11) comprising elements (14, 15) able to decalcify the washing water and elements (12, 13) able to regenerate the decalcification filtering elements, and a tank (17) for the execution, with clean water (28), of cycles to regenerate said filtering elements. The device comprises a group of load valves connected to the mains water supply and having two valves (22a, 22b), able to be selectively and independently activated, associated downstream with a crossed-flow distributor unit (18) having two inlets (19a, 19b) and three outlets (20a, 20b, 20c). A first outlet (20a) of said crossed-flow distributor unit (18) is connected to said anti-calcium unit (11) in order to feed washing water to be sent to said decalcification elements (14. 15), a second outlet (20b) of said distributor unit (18) is connected, by means of an outlet (37), to the washing chamber for mixing hard water with decalcified water, and a third outlet (20c) is connected with said tank (17) of the regeneration water, in order to send the water to said elements (12, 13) to regenerate the decalcification filtering elements.
