Abstract
The system () for controlling the combustion () of a cooking oven burner (), comprises in combination a thermostat valve () with a rotary hand knob () and a non-electric temperature sensor () for modulating the burner flame (), and an electromagnetic safety valve kept open for ignition, and a electronic module () supplying in a first moment a DC power supply to the safety valve (), which is then maintained open by a thermocouple () heated by the main flame (). A common electrode () is provided both for electronic flame detection and ignition. During the burner pre-ignition step, the absence of flame detection signal (If) permits the gas flow (G) to be cut off after a short timed interval, irrespective of the thermocouple response. In the event of the AC power supply being cut off, the thermocouple () and the thermostat valve () keep the burner modulated independently.
