<p>A dispensing device for substances, particularly washing agents, for a domestic appliance, particularly a washing machine, comprises:
- a main body (20", 30"), arranged for being fixed in a stationary position with respect to a structure of the appliance,
- a support means (40) of a substance which is to be delivered,
- an actuation system (50") which is electrically controllable for causing delivery of the substance. The actuation system comprises at least one drive element (61 ") and one driven element (40), the driven element being adapted to cooperate with the drive element to allow said delivery. The dispensing device further comprises a position or movement transducer (70, A) having a detection unit (70) excitable by excitation means (A). The detection unit is associated with, or carried by, the main body (20", 30") and the excitation means are operatively associated to, or incorporated in, at least one of the drive element and the driven element. The transducer (70, A) is arranged for detecting a relative movement between the drive element or the driven element with respect to at least one part of the main body (20", 30").</p> |
