Abstract:
1. A washing machine comprising a support structure in which is suspended a washing chamber in which a laundry drum is mounted to be rotatable, and detector means for providing electrical signals indicating the level of the washing liquid in said chamber, said detector means comprising an inductive transducer including a coil and an associated core, the relative position of which is variable according to the level of the washing liquid in such a way that the inductance of said coil varies accordingly; said inductive transducer being coupled to the laundry drum so that the inductance of said coil is also variable according to the weight of the load contained in said drum; wherein the transducer has associated processing and control means for, in at least a first state, correlating the inductance of the coil of the transducer with the weight of the aforesaid load and, in at least a second state, correlating the inductance with the level of the liquid in the washing chamber.
