Abstract (en)
A washing and/or drying appliance (100) is proposed. The appliance comprises: an electric load (205), a driving arrangement (210,215,C) for driving the electric load (205), the driving arrangement (210,215,C) having first (T 205,IN1 ) and second (T 205,IN2 ) terminals coupleable, respectively, to a line terminal (T L ) and to a neutral terminal (T N ) providing a reference voltage ( V CC ), an inrush current limiting device (R FUSE ;R NTC ) and a switching device (RL;RL 1 ) between the reference terminal (T N ) and the second terminal (T 205,IN2 ) of the driving arrangement (210,215,C), the switching device (RL;RL 1 ) being operable in first or second states preventing or allowing, respectively, an electric current to flow through the inrush current limiting device (R FUSE ,R NTC ), and a sensing network (R PD ) for sensing the first or second states of the switching device (RL;RL 1 ) and for providing a corresponding state signal ( S STATE ;S* STATE ), the sensing network (R PD ) having a first terminal (T RPD,1 ), and a second terminal (T RPD,2 ) coupled to a reference terminal providing a further reference voltage ( GND ) lower than the reference voltage ( V CC ), wherein, during sensing: in the first state of the switching device (RL;RL 1 ) the reference terminal (T N ) and the first terminal (T RPD,1 ) of the sensing network (R PD ) being coupled to each other such that the first terminal (T RPD,1 ) of the sensing network (R PD ) receives the reference voltage ( V CC ) and the state signal ( S STATE ;S* STATE ) takes a first level (S STATE,H ) equal to the reference voltage ( V CC ), in the second state the state signal ( S STATE , S* STATE ) taking a second level (S STATE,I ;S STATE,L ) lower than the first level (S STATE,H ).
