Claims

[Claims for Utility Model Registration] ■ A thermocouple 4 that is heated by the combustion flame of the burners 1 and 2 and generates a thermoelectromotive force, and an electromagnetic device interposed in the middle of the fuel supply path 8 to the burners 1 and 2. An electromagnet M for actuating the safety shutoff valve 9 is connected in series, and during combustion in the burners 1 and 2, the electromagnet M is excited by the electromotive force of the thermocouple 4 to keep the safety shutoff valve 9 open. A fire extinguishing safety control circuit B is configured to automatically close the safety shutoff valve 9 by deenergizing the electromagnet M due to a decrease in the electromotive force of the thermocouple 4 as the burners 1 and 2 are extinguished. is a combustion appliance, in which a power source E that generates a reverse activation force in a direction to cancel the thermoelectromotive force generated by the thermocouple 4 is connected in parallel to the fire extinguishing safety control circuit B, and A combustion appliance characterized in that a switch R5 is provided which can switch between supplying and not supplying the back electromotive force of the power source E to the fire safety control circuit B. (2) The power source E is composed of a battery E□ and a capacitor C1 that is charged by the battery E□ when no back electromotive force is supplied to the fire safety control circuit B, as set forth in claim 0 of the utility model registration claim. combustion appliances. (2) The combustion appliance according to claim 0, wherein the power source E is a battery E2. (2) The combustion appliance according to claim 0, wherein the power source E is a thermocouple 4A that is heated by the combustion flames of the burners 1 and 2 and generates the back electromotive force.
