Washing and rinsing agents dispensing device, particularly for a dishwasher machine

An integrated dispensing device (1) for a rotatable door of a washing machine, in particular a dishwasher machine, comprising

• a support body (2) wherein there are provided first and second dispensers (5-10;
• 13-18), adjacent one another, for a washing agent and a rinsing agent, respectively;
• and
• an electrically-controlled actuator device (12), coupled to the first dispenser (5-10) such that when the door is closed a first energisation of the actuator device (12) causes the dispensing of the washing agent, and coupled to the second dispenser (13-18) through a transmission mechanism (40;
• 61-65) predisposed to become enabled to operate after a first energisation of the actuator device (12) after the door is closed, to allow the dispensing of the rinsing agent as a consequence of at least one subsequent energisation of the actuator device (12);
• the second dispenser (13-18) comprises
• a main chamber (13) adapted to contain a plurality of doses of rinsing agent,
• a dosing chamber (14) having a predetermined volume, corresponding to that of a dose, and having an inlet opening (14a) and an outlet opening (14b) to be coupled with the main chamber (13) and with a discharge conduit (15), respectively, and
• a valve device (16) including an obturator (18) mounted movable in the dosing chamber (14) and controlled by said actuator device (12) such that
• when the actuator device (12) is energised, after the transmission mechanism (40;
• 61-65) has been enabled for operation, the obturator (18) passes from a rest position in which it uncouples the dosing chamber (14) from the main chamber (13), to a loading position, opening the inlet (14a) and keeping constantly closed the outlet (14b) of the dosing chamber (14), to allow a flow of rinsing agent from the main chamber (13) to the dosing chamber (14) through said inlet (14a);
• and
• when the actuator device (12) is subsequently de-energised, the obturator (18) returns from the loading position to the rest position, opening the outlet opening (14b) and still closing the inlet opening (14a) of the dosing chamber (14);
• the arrangement being such that during the displacement of said obturator (18) between the rest position and the loading position, the main chamber (13) remains permanently uncoupled from the discharge conduit (15).
