く調整が難かしい欠点があつた。Problems that the invention aims to solve When conventional kerosene heaters are used for long periods of time, the rectifying plate of the inner flame tube installed at the top of the wick guide tube becomes oxidized and blackens depending on the frequency of use, and the degree of blackening is uneven. For example, the temperature at the top of the core guide tube (near the heat deformation element) becomes high as shown in the conventional product in Figure 4, and the displacement variation of the heat deformation element (bimetal) is large and the setting range of the heat deformation element (bimetal) is The disadvantage was that it was narrow and difficult to adjust.

げたものである。Means and Effects for Solving the Problems The present invention blackens the rectifying plate of the inner flame tube, which affects the temperature of the heat deformable element installed near the top of the wick guide tube. By setting the emissivity ε of the rectifying plate to a value equivalent to that after use, it is possible to reduce the temperature change near the heat deformable element (bimetal), thereby expanding the adjustment range of the heat deformable element (bimetal).

A combustion tube 4 is provided at the upper end of the core guide tube 2 and the core outer tube 3. A thermal deformable element (hereinafter explained using a bimetal) 5 is located near the upper end of the core guide tube 2.
is provided so as to be in contact with one end of an interlocking rod 8 which is interlocked with the earthquake-resistant automatic fire extinguishing system 7. This interlocking rod 8 is provided with compression springs 10 (the same effect can be obtained with a weight) as shown in FIG. 1, and the force of these springs 10 acts to push down the interlocking rod 8. An inner flame cylinder 11 is provided on the upper part of the bimetal 5, and a rectifying plate 12 is provided in the inner flame cylinder 11 so as to face the upper surface of the bimetal 5. The entire surface of the current plate 12 is subjected to blackening treatment (or the same effect can be obtained by annealing).

らず温度変化が少なくなる。 In the above configuration, during steady combustion, the temperature near the top surface of the core guide cylinder 2 is as shown in Figure 2.
When the temperature of T 1 is maintained in an oxygen-deficient state, there is a lack of air for combustion, and the combustion reaction near the tip of wick 1 slows down, causing the reaction temperature to drop. Therefore, the temperature near the core guide tube 2 decreases as shown at T2 .
Here, the bimetal 5 provided on the top surface of the core guide cylinder 2 is displaced by utilizing this temperature change, and the deformation force of this bimetal 5 is utilized to move the inverted L-shaped interlocking rod 8 to the bimetal 5 when oxygen is depleted. Rotate it by the deforming force of and remove the interlocking rod 8 from the locking part 14.
It is pushed down by the force of the compression spring 10. Therefore, the earthquake-resistant automatic fire extinguishing device 7, which is in contact with the other end of the interlocking rod 8, is pushed up by the lever 9 and activated to extinguish the fire. This operation reduces the temperature change in the vicinity of the bimetal because the blackened rectifier plate 12 is provided above the heat deformable element 5 even during long-term use. Temperature changes will remain the same.

その調整が安易となる等有益なものである。Effects of the invention According to this invention, in an indoor oxygen-deficient state, the interlocking rod can be rotated by the displacement due to the temperature of the bimetal, and the interlocking rod can be pushed down by the spring force to extinguish the fire using an earthquake-resistant automatic fire extinguishing system, thereby reducing the danger of oxygen depletion. This can be prevented, and even during long-term use, temperature changes near the bimetal can be reduced by blackening the rectifier plate, which reduces bimetal displacement variation, allows for a wide bimetal setting range, and makes adjustments easy. This is a useful thing.
