PURPOSE:To make it possible to actuate an automatic aseismatic fire extinguisher to extinguish fire at the time of oxygen deficiency and to lock the same at the time of no-fuel burning by providing a thermal deformation element sensing a temperature fluctuation at the time of oxygen deficiency within the room and changing its position, and also providing a no-fuel burning locking knob pushing up and fixing an operating frame to the side of an interlocking member at the time of no-fuel burning. CONSTITUTION:When indoor air becomes oxygen deficient, the temperature on the surface or in the vicinity of a combustion cylinder 6 lowers. This displaces a bimetal 5 provided between an outer flame cylinder 26 of the combustion cylinder 6 and an outer cylinder 27. When an interlocking member 8 having an inverted L-shaped tip end is rotated in the direction indicated by arrow by utilizing this displacement force, the interlocking member 8 is dis engaged from an engaging part 13 and falls. As a result, an automatic aseismatic fire extin guisher 7 operates and extinguishes fire. Further, when an idle burning locking knob 18 is provided at the other end of a lock lever 14 provided below the interlocking member 8, and the lower 14 is set in the direction indicated by arrow along a slit 21 of a no-fuel burning lock guide 19, the interlocking member 8 is pushed up through the lever 14, and an automatic aseismatic fire extinguisher cannot operate even when the temperature lowers at the time of no-fuel burning. Therefore, complete no-fuel burning can be performed. |
