る。(Prior Art and Problems) There are various causes of backflow of exhaust gas, and one of them is the sealing of the house. That is, due to the development of sash, etc., houses have become airtight, and when a combustion appliance such as that shown in FIG. 1 is used under such airtight conditions, there is a risk that exhaust gas may flow back into the room from the exhaust stack. this is,
For example, by turning on the ventilation fan in the kitchen, etc.
This is an example of a negative pressure in the room and exhaust gas flowing back into the room and contaminating the room. In such a case, the present invention provides
This system immediately and automatically stops combustion in combustion appliances to prevent pollution from indoor exhaust gas.

ことができる。(Function) Figure 2A shows a state in which exhaust is normally exhausted.
The case of FIG. 2B shows a case where backflow occurs.
In the case of FIG. 2B, when a backflow occurs as shown by the arrow in the figure, the exhaust gas flows out from the backflow outflow section 8, but since a draft is acting on the exhaust pipe 4,
The box body 2 receives combustion air from the air supply section 9 below.
flow inside. In this case, a part of the exhaust gas flows directly to the pilot burner 10 via the backwind guide pipe 11, and immediately extinguishes the pilot flame. Therefore, the thermocouple ceases to act, closing the solenoid valve 13 and extinguishing the main burner 15. In this way, the combustion appliance 1 is housed in the box body 2, and the air supply cylinder 3 is provided on the ceiling part 14 of the box body 2, and the back wind outlet part 8 and the air supply part 9 are provided above and below the partition member 7. By virtue of the configuration in which a reverse wind guide pipe 11 is installed between the baffler 5 and the pilot burner 10, the supply of fuel gas can be immediately stopped even if air is blown.

感知消火できる最大の利点がある。(Effects of the Invention) As described above, the present invention prevents indoor air pollution by adopting a unique configuration that immediately guides the exhaust gas to the combustion appliance and stops the fuel gas even if a backflow occurs in the exhaust gas. It has an excellent preventive effect. In particular, since the supply section is arranged at a high position, the greatest advantage is that contamination of the room by exhaust gas can be detected and extinguished before it affects the human body.
