Laundry washing machine with a water softening device

摘要

Laundry washing machine (1) comprising an outer casing (2) and, inside said outer casing (2), a washing tub (3), a detergent dispensing assembly (9), a fresh-water supply circuit (10) for selectively channeling a flow of fresh water from the water mains towards the detergent dispensing assembly (9) and/or the washing tub (3), and a water softening device (11) interposed between the fresh-water supply circuit (10) and the detergent dispensing assembly (9) or the washing tub (3), and being structured for reducing the hardness degree of the fresh water supplied to the washing tub (3); the water softening device (11) comprising: a water-softening agent container (26) which is crossed by the fresh water arriving from the fresh-water supply circuit (10) and is filled with a water softening agent; a regeneration-agent reservoir (27) being structured to receive a salt or other regeneration agent for performing a regeneration of the water softening function of the water softening agent; and a water supply circuit (28) for selectively channeling a given amount of fresh water into the regeneration-agent reservoir (27) to form brine; and an electrically-powered brine-circulating pump assembly (29) interposed between the water-softening agent container (26) and the regeneration-agent reservoir (27), and being structured for transferring/moving the brine from the regeneration-agent reservoir (27) to the water-softening agent container (26) when activated, and for watertight sealing/isolating the regeneration-agent reservoir (27) from the water-softening agent container (26) when deactivated.
