This heat input conducts heat to the thermoelectric generator 4 and naturally dissipates heat from the radiation fins 6, and the thermoelectric generator unit 8 generated according to the resulting temperature difference between the heating portion and the heat radiating portion of the thermoelectric generator 4 is generated. The electric power causes the fan 13 to start driving. By the air blown from the driven fan 13, the heat radiation fins 6 are cooled, the amount of heat radiation is increased, the temperature of the heat radiation portion of the thermoelectric generator 4 is lowered, and the electromotive force of the thermoelectric generator unit 8 is increased, so that the fan 13 The rotation speed becomes faster. Eventually, steady operation was performed with the heat balance of the entire combustion device balanced.

うという問題点を有していた。Problems to be Solved by the Invention It is necessary to adjust the combustion amount strongly according to the heating load in the room. However, in the above-mentioned configuration, the heating portion temperature of the thermoelectric generator 4 is low when the combustion amount is weak. As a result, a sufficient electromotive force cannot be obtained, and the rotation speed of the fan 13 decreases. Therefore, the temperature of the heat radiation portion of the thermoelectric generator 4 rises, and the electromotive force of the thermoelectric generator unit 8 decreases. After all, the heat balance is performed in the same steady state as in the strong combustion, but the electromotive force of the thermoelectric generator unit 8 is not obtained, the rotation speed of the fan 13 is low, and the convection heating is performed as compared with the strong combustion. There is a problem that the outer frame 10 is overheated at the same time when the effect is remarkably deteriorated.

る。Action The present invention has the above-described configuration, so that the cooling unit of the thermoelectric generator is forcibly cooled by the air flowing into the intake port.
The temperature of the heat radiating portion of the thermoelectric generator is stable without being affected by the ambient temperature of the heat radiating portion of the thermoelectric generator or the temperature of the entire combustion device. Further, since the temperature of the outer cylinder does not change even if the combustion amount is adjusted to be strong or weak, the temperature of the heat radiating portion of the thermoelectric generator is stable. Therefore, since the temperature difference between the heating portion and the heat radiating portion of the thermoelectric generator is constant, the electromotive force of the thermoelectric generator is also constant.

In FIG. 1 and FIG. 2, the thermoelectric generator element 4 is brought into close contact with the outer peripheral surface of the outer cylinder 3 and the heat radiation fins 6 are brought into close contact to form a thermoelectric generator element unit 8. An intake port 14 is formed in the reflecting plate 9 so as to face each other. A blower port 15 is formed above the reflection plate 9 and a fan 13 is installed.

起電力が得られる。In the above configuration, the outer combustion tube 2 is directly heated to a high temperature by the primary combustion flame 16 formed between the inner combustion tube 1 and the outer combustion tube 2, and the outer tube 3 is also heated by the radiant heat of the outer combustion tube 2. It gets hot. Then, the heating portion of the thermoelectric generator unit 8 is heated by heat conduction from the outer cylinder 3, while the heat radiation fins 6 naturally radiate heat. Due to the electromotive force of the thermoelectric generator unit 8 resulting from this, the fan 13 starts driving. The driven fan 13 sucks the air 17 from the intake port 14, and the heat radiation fins 6 are forcibly cooled by the air 17 to lower the temperature of the heat radiation portion of the thermoelectric power generating element 4 and further increase the electromotive force of the thermoelectric power generating element unit 8. However, the rotation speed of the fan 13 becomes faster. Eventually, the thermoelectric generation element unit 8 becomes steady in a state where the heat balance of the entire combustion device is balanced, and sufficient electromotive force is obtained.

ある。Next, the case where the amount of strong combustion is adjusted to the amount of weak combustion will be described. Due to the decrease in the amount of combustion, the temperature of the outer flame tube 2 drops,
Since the amount of radiant heat from the outer flame cylinder 2 to the outer flame cylinder 3 also decreases, the temperature of the outer cylinder 3 decreases. However, the amount of heat taken from the outer cylinder 3 by the air flowing inside or outside the outer cylinder 3 by cooling also decreases, so that the temperature of the outer cylinder 3 does not decrease so much. Therefore, the temperature of the heating portion of the thermoelectric generator element unit 8 heated by heat conduction from the outer cylinder 3 does not decrease so much. On the other hand, since the heat radiating portion of the thermoelectric generator is forcibly cooled, the temperature of the heat radiating portion is stable without being influenced by the ambient temperature of the thermoelectric generator and the temperature of the entire combustion apparatus. As a result, the temperature difference between the heating portion and the heat radiating portion of the thermoelectric generator is constant, so that the electromotive force of the thermoelectric generator unit 8 is constant. Therefore,
The electromotive force of the thermoelectric generator unit 8 is constant irrespective of the amount of combustion, and has the effect of always obtaining a stable air flow rate.
