Detecting device of the angular position of a rotating member of an electric household appliance, in particular the drum of a washing machine

A detecting device for detecting the angular position of an electric household appliance rotating member, typically the drum of a top-load washing machine or dryer, comprising generating means of a magnetic field arrangeable in a fixed position with respect to the rotating member, for example integrally mounted on the frame of the electric household appliance;

• interaction means with the magnetic field generating means, integrally arrangeable in use on the rotating member in a position so as to periodically transit in front of the magnetic field generating means and in position adjacent to the same;
• and means adapted to generate an electrical signal when they are crossed by flux lines of the magnetic field, integrally arranged with the magnetic field generating means;
• characterised in that said magnetic field generating means are shaped so as that said periodic transit of the interaction means causes a spatial variation of arrangement of the magnetic field flux lines between a first and a second field configuration;
• and in that, in combination, said signal generating means are arranged, with respect to the interaction means, on the same side as the magnetic field generating means, but in a position so as to be crossed by the flux lines only in said second field configuration.
