GAS-TIGHT DEVICE Russian patent published in 2014 - IPC F24C3/12 

FIELD: electricity.

SUBSTANCE: gas-tight device includes an ignition plug, a burner located in the surface area, a thermocouple having a possibility of generating a thermoelectromotive force at spark ignition in the burner, an electronic valve unit, to which the thermocouple is electrically connected via multiple connecting lines and which opens and closes for control of gas supply to the burner according to transfer of the thermoelectromotive force generated in the thermocouple, a bimetallic switch connected in series to one of the multiple connecting lines and located in the other surface area different from that in which the burner is located. The bimetallic switch has a possibility of responding to variation in temperature of thermal emission on the vessel surface, deactivation for switching off transfer of the thermoelectromotive force to the electronic valve unit when thermal emission temperature exceeds the pre-set temperature level, and activation for transfer of the thermoelectromotive force to the electronic valve when the thermal emission temperature is lower than the pre-set temperature level.

EFFECT: preventing risk of overheating and fire as a result of negligence of a user at preparation of food.
