PURPOSE:To make it possible to safely extinguish fire under oxygen deficiency within the room and to open a door even when a bimetal comes into contact with an interlocking member during the temperature rise by providing the thermal deformation element (bimetal) sensing a temperature fluctuation under an oxygen deficiency and changing its position, and providing a one-way opening door riding over the interlocking member at the time of a temperature rise and pressing the interlocking member at the time of a temperature fall, at the tip end of the thermal deformation element. CONSTITUTION:When indoor air becomes oxygen deficient, the temperature on the inner surface or in the vicinity of a combustion cylinder 6 is lowered, and a bimetal 5 provided between an outer flame cylinder 26 and an outer cylinder 27 is displaced. 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 disengaged from an engaging part 13 and is lowered, and an automatic aseismatic fire extinguisher 7 operates through an operating frame 9 provided at the lower end of the interlocking member 8 and extinguishes fire. In this case, while the temperature is rising even when a one-way opening door 12 provided at the tip end of the bimetal 5 comes into contact with the interlocking member 8, the door 12 can be opened and easily clear the interlocking member. |
