Integrated washing agent dispenser, in particular for a dishwasher

An integrated dispensing device for a pivotable door of a washing machine, comprising

• a support body having an elongate shape, wherein there are provided first and second, longitudinally adjacent, dispensers, for a washing agent and a rinse agent, respectively;
• and
• an electrically controlled actuator device, coupled to the first dispenser such that when the door is closed a first energization of the actuator device causes the dispensing of the washing agent, and coupled to the second dispenser through a transmission mechanism including a pivotable interconnecting member acting to make said mechanism operative after a first energization of the actuator device after the door has been closed, to allow the dispensing of the rinse agent by at least one subsequent energization of the actuator device;
• said interconnecting member being adapted to assume by gravity an inactive position in which it makes said mechanism inoperative, as a consequence of opening said door;
• the actuator device comprising a stationary structure and a movable member;
• wherein said movable member of the actuator device is a slider displaceable relative to said structure along the longitudinal direction of said body, between a rest position and a working position;
• the actuator device comprising a wire of a shape-memory material, having its ends connected to said structure, and extending along a U-shaped path which passes around one portion of the slider opposite said structure;
• wherein when said wire is energized by means of an electric current, it shortens and causes a displacement of the slider from the rest position toward the working position, against the action of resilient contrast means, and when said wire is de-energized it re-elongates allowing the displacement of the slider toward the rest position;
• said interconnecting member being carried by and connected pivotably to said slider;
• wherein said stationary structure carries a position sensor device adapted to generate an electric signal when the slider reaches its working position.
