Abstract: A water dispensing device for a washing appliance has a body and a lid defining an internal cavity and, within the internal cavity, a flow conduit for water from an inlet to an outlet. On the flow conduit an air-break is provided. One or more non-return valves are arranged on the flow conduit within the internal cavity and upstream of the air-break.

Abstract: An integrated component for supplying and treating water for a dishwashing machine having a washing tank includes a monolithic body of plastics material, within which an inlet conduit for water, a chamber containing substances with water-softening properties, into which the inlet conduit leads, a salt-containing reservoir arranged in the lowermost portion of the body and having a filler tube for loading the salt and to be connected to the washing tank, a compartment for blowing out vapours having an inlet opening to be connected to the washing tank and an outlet opening, an outlet conduit of water, a conduit for supplying water to the reservoir to produce the brine, and a conduit connecting the reservoir to the chamber are defined. The monolithic body has at least one protrusion, to which a sealing gasket is associated, for the direct connection within an opening of corresponding shape of the washing tank.

Abstract: A pump for regenerating a decalcifying device of a dishwasher. The pump brings about a flow of regenerating brine in a chamber containing substances with water-softening properties of a decalcifying device of a dishwashing machine. The pump includes: a body (10) in which a brine inflow conduit (16) provided with a one-way valve (18) and a brine outflow conduit (12) provided with a one-way valve (14) are defined; a solenoid (20) having a longitudinal axis (24) and arranged within the body (10); and a core controlled by the solenoid (20), mobile along the axis (24), provided with return elastic means and having an upper end associated to the body (10) and a lower end connected to a centre portion of a membrane (44), whose peripheral portion is fixed to the body (10).

Abstract: A system for supplying and treating water for a dishwasher. The system includes electronic control unit (ECU) and an indicator adapted to provide signals or data indicative of the hardness of the water. The control unit controls, and if necessary selectively varies, in predetermined ways, as a function of the water hardness indicated by the indicator, and at least two of the following parameters of the regeneration of the water-softening substances: the quantity of water used for forming the brine used for each operation of regenerating the softening substances contained in said first tank (24), the quantity of water used for washing the softening substances after each regeneration operation, and the frequency of the operations of regenerating and washing said softening substances.

Abstract: A dishwasher system having an electronic control unit (ECU). The control unit is designed to control selectively, in predetermined ways, as a function of the hardness of the water, and through the electric valves: the quantity of water used for forming the brine used for each operation of regenerating the softening substances contained in the first tank; and the frequency of the operations of regenerating and washing the softening substances.

Abstract: A diverter valve device (10) including a body (12), in which a chamber (14) is defined, which is able to be flown through by a pressurized fluid flow; a rotatory plug (16), which is mounted on the body (12) and is adapted to rotate about a rotation axis (X-X); at least one inlet (18), which is provided in the body (12) and is fluidly arranged upstream of the chamber (14); and a pair of outlets (20a, 20b), which stem from the body (12) and are fluidly arranged downstream of the chamber (14). The body (12) has a substantially axial seat (22a) and a substantially radial seat (22b), which are fluidly arranged between the chamber (14) and one outlet (20a) and the other outlet (20b), respectively. The plug (16) is suited to assume a first and a second operating condition, in which it (16) respectively frees and obstructs the substantially axial seat (22a) as well as respectively obstructs and frees the substantially radial seat (22b).
