摘要:
A safety control system (10) for an electromagnetic door lock (1) of an electric household appliance, wherein a blocking pawl (3) is controlled by the movement of a core (12) of an electromagnet (11), including a supplying circuit (18) of a coil (15) of the electromagnet, power supplying means (20) to supply electric pulses in the circuit for energizing the coil and a PTC element (21) arranged in series in the circuit; wherein power supplying means are of the type adapted to generate first pulses (51 ) for taking the pawl to a blocking position and second pulses (52), having a polarity opposite to the first, for taking the pawl to a releasing position; and including means (22) for determining, according to the parameters of an operating cycle of the electric household appliance, the emission of at least one train (53) of first pulses by the power supplying means.
