Abstract
An electrical appliance having at least one electrical load, and a digital control system managing flows of electric current of supply of the at least one electrical load, wherein the digital control system of the electrical appliance transmits information to an external control device, wherein said information comprises first information regarding authorization or non-authorization for an interruption of the supply of electric voltage to the electrical appliance by the external control device, the digital control system of the electrical appliance generating the first information of its own operating state.
Claims15
An electrical household appliance system that comprises:
- an electrical appliance, having at least one electrical load and a digital control system that manages flows of electric current of supply of the at least one electrical load;
- and
- a control device operatively set between an electrical-supply line of the electrical appliance and a corresponding electric voltage-supply source, the control device having a digital control system with a first controllable switch for managing in ON-OFF mode the electric voltage from the supply source to the electrical appliance;
- wherein the digital control system of the control device interfaces to a communication network and receives through said communication network instructions for switching the first controllable switch;
- wherein the digital control system of the electrical appliance transmits information spontaneously, and the digital control system of the control device receives said information;
- wherein said information comprises first information regarding authorization or non-authorization to an interruption of the supply of electric voltage to the electrical appliance by the control device, the digital control system of the electrical appliance generating the first information of its own operating state;
- and
- wherein the digital control system of the control device causes switching of the first controllable switch as a function of one said instruction for switching and said first information.

A method for control of power consumption in a domestic environment, the method comprising:
- providing an electrical appliance;
- providing a control device between an electrical-supply line of the electrical appliance and a corresponding electric voltage-supply source, the control device being able to cause an interruption of the supply of electric voltage from said supply source to said supply line via a first controllable switch;
- and
- coupling the control device to a communication network for receiving therefrom instructions for switching the first controllable switch;
- wherein the electrical appliance is capable of transmitting information to the control device spontaneously;
- wherein said information comprises first information regarding authorization or non-authorization for an interruption of the supply of electric voltage to the electrical appliance by the control device, the electrical appliance generating the first information of its own operating state;
- and
- wherein the control device provides for interrupting or not interrupting the supply of electric voltage to the electrical appliance of one said instruction for switching and said first information.

A control device for an electrical household appliance system operatively set between an electrical supply line of an electrical appliance and a corresponding electric voltage supply source, the control device having a digital control system with a first controllable switch for managing in an ON-OFF mode the electric voltage from the supply source to the electrical appliance:
- wherein the digital control system interfaces to a communication network and receives via said communication network instructions for switching of the first controllable switch;
- wherein the digital control system of the control device sets up a communication line with the electrical appliance;
- wherein said communication line is unidirectional and consists of a receiver;
- and
- wherein the digital control system causes switching of the first controllable switch as a function a first information transmitted spontaneously by the electrical appliance, relating to authorization or non-authorization to an interruption of the supply of electric voltage thereof.

An electrical household appliance system that comprises:
- an electrical appliance, having at least one electrical load and a digital control system that manages flows of electric current of supply of the at least one electrical load;
- and
- a control device operatively set between an electrical-supply line of the electrical appliance and a corresponding electric voltage-supply source, the control device having a digital control system with a first controllable switch for managing in ON-OFF mode the electric voltage from the supply source to the electrical appliance;
- wherein the digital control system of the control device interfaces to a communication network and receives through said communication network instructions for switching the first controllable switch;
- wherein the digital control system of the electrical appliance transmits information, and the digital control system of the control device receives said information, said information being encoded by controlled variations of said flows of electric current performed via the managing;
- wherein said information comprises first information regarding authorization or non-authorization to an interruption of the supply of electric voltage to the electrical appliance by the control device, the digital control system of the electrical appliance generating the first information of its own operating state;
- wherein the digital control system of the control device causes switching of the first controllable switch as a function of one said instruction for switching and said first information;
- and
- wherein encoding of said information includes at least:
- a first datum of start of transmission represented by a current pulse of a first duration, followed by a fixed pause;
- a second datum indicating the type of information represented by a current pulse having a duration depending upon a first value to be transmitted, followed by a fixed pause;
- a third datum indicating the contents of the information represented by a current pulse having a duration depending upon a second value to be transmitted, followed by a fixed pause;
- and
- a fourth datum that replicates the third datum and concludes the transmission.
