Embodiment Construction
[0037] The invention has proven to be particularly advantageous, since it allows to keep the regeneration cycle to a minimum, so that the salt consumption is reduced, while guaranteeing the softening and the effectiveness of the entire washing process, without using additional instruments in the machine for measuring the hardness of the water. expensive sensor.
[0038] refer to figure 1 and figure 2 , numeral 1 designates the entire laundry machine, which comprises: an outer box casing 2, preferably (but not necessarily) parallelepiped-shaped, resting on the floor; a laundry treatment group, placed on said casing 2 and further preferably includes a substantially bell-shaped laundry tub 3 suspended in a floating manner inside the housing 2 via a suspension system comprising: a plurality of coil springs (not shown), preferably (but not necessarily ) is combined with one or more shock absorbers (not shown); and a substantially bell-shaped laundry drum 4 for accommodating laun...

The invention relates to a laundry treatment machine (1) comprising an external housing (2); a washing tub (3) arranged inside the housing (2); a rotatable drum (4) , the drum is arranged in the washing tub (3) in an axially rotating manner and is designed to receive the laundry to be washed; a softening device (10), which is provided with: an ion exchanger (11) and a regeneration device (12), the ion exchanger is designed to receive clean water from the water supply main (9) and reduce the hardness of the clean water in order to supply demineralized water to the washing tub (3), the regeneration device is designed to use performing a regeneration cycle to regenerate the ion exchanger device (11); a control panel (13) configured to allow the user to select a washing program comprising a plurality of washing stages; an electronic control unit (15), The electronic control unit is configured for controlling the regeneration device (12) in order to perform the regeneration cycle. The control panel (13) is further configured to allow the operator to enter first data indicative of said fresh water hardness and / or to enter second data indicative of a selected wash program during one or more wash stages Demineralized water or alternatively clean water is supplied to the washing tub (3). The electronic control unit (15) is further configured for: changing the total amount of demineralized water to be used during the selected washing program based on said first and / or second data, determined to have been supplied by the ion exchanger ( 11) The total amount of demineralized water supplied, and the regeneration device (12) is controlled so as to activate the regeneration cycle based on the determined demineralized water.
Description
[0001] The invention relates to the technical field of laundry washing. In particular, the present invention relates to a washing machine performing a water softening process. Background technique [0002] Today, laundry machines are widely used, including both "simple" washing machines (ie, washing machines that can only wash and rinse laundry) and wash-dryers (ie, washing machines that are also capable of drying laundry). [0003] In this regard, the term 'laundry machine' may indiscriminately refer to a washing machine, or a laundry washing and drying machine, or a laundry drying machine in this specification, which is not explained differently. [0004] As is well known, a laundry machine generally comprises a detergent dispenser located within a box-like housing directly above the wash tub and structured for use with a washing cycle manually selected by the user with water from a water supply A given total amount of detergent, softener and / or other cleaning agents, suita...
