ELECTRICAL HOUSEHOLD APPLIANCE SYSTEM

A control device for an electrical appliance operatively set between an electrical supply line of the electrical appliance and a corresponding alternating current (AC) voltage supply source, the control device having a digital control system that encodes information via controlled interruptions of the AC voltage of supply of the electrical appliance and has a first controllable switch managing in an ON-OFF mode the AC voltage from the supply source to the electrical appliance, wherein the encoding comprises carrying out a coding of information as sequences of interruptions having fixed duration of the AC voltage of supply of the electrical appliance, said interruptions having fixed duration being separated by a corresponding interval having variable duration, wherein the information to be transmitted is associated to the variable duration of the interval and the fixed duration of the interruptions is such as not to perturb operation of the electrical appliance.
