An integrated washing agent dispenser, in particular for a dishwasher. The dispensing device (1) for a pivotable door of a dishwasher, comprises a support body (2) having an elongate shape, wherein there are provided first and second, longitudinally adjacent, dispensers (5-7; 9, 10), for a washing agent and a rinse agent, respectively; and an electrically controlled actuator device (13), comprising a stationary structure (15) and a mobile member (18), coupled to the first dispenser (5-7) such that when the door is closed a first energisation of the actuator device (13) causes the dispensing of the washing agent, and coupled to the second dispenser (9, 10) through a transmission mechanism (9, 30, 31) including a pivotable interconnecting member (30) acting to make said mechanism operative after a first energisation of the actuator device (13) after the door has been closed, to allow the dispensing of the rinse agent by at least one subsequent energisation of the actuator device (13). The interconnecting member (30) is adapted to assume by gravity an inactive position in which it makes said mechanism inoperative, as a consequence of opening the door. The movable member (18) of the actuator device (13) is a slider displaceable relative to said structure (15) along the longitudinal direction of the body (2), between a rest position and a working position. The actuator device (13) comprising a wire (20) of a shape-memory material, having its ends connected to said structure (15), and extending along a U-shaped path which passes around one portion (18a) of the slider (18). The arrangement is such that when the wire (20) is energised, it shortens and causes a displacement of the slider (18) from the rest position toward the working position, against the action of a contrast spring (21), and when the wire (20) is de-energised it re-elongates allowing the displacement of the slider (18) toward the rest position. The interconnecting member (30) is carried by and connected pivotably to the slider (18). |
