Abstract:
1. A device for saving energy by eliminating electricity consumption on standby for a functional group of controlled appliances comprising at least one main appliance, the device comprising: a connection to the electricity network; a power supply; at least one connection for supplying power to said functional group of controlled appliances including said main appliance; a relay for switching on and for switching off the power supplied by the device to said functional group of controlled appliances; measurement function part implementing a measurement function in hardware and/or in software for providing an information representative of the power consumed by said functional group of controlled appliances; an integration and/or averaging function part implementing an integration and/or averaging function in hardware and/or in software, comprised in said measurement function, for making the information representative of the power consumed by said functional group of controlled appliances insensitive to the waveform of the current flowing in the controlled load involved in the measurement; a comparison function part implementing a comparison function in hardware and/or in software, for comparing said information representative of the power consumed by said functional group of controlled appliances with a predetermined threshold; means receptive to a command from the user, at least one of these means being dedicated exclusively to the device; and a control part implementing a control function, wherein a command from the user causes a supply of power to said functional group of controlled appliances for a first predetermined time, the supply of power being maintained so long as the information representative of the power consumed by said functional group of controlled appliances is greater than a predetermined threshold, and wherein the supply of power to said functional group of controlled appliances, including said main appliance, being automatically stopped by the control part when the information representative of the power consumed by said functional group of controlled appliances is less than the predetermined threshold for a second predetermined time.
