In recent years, houses have become more airtight, and for some reason, the air pressure indoors can become lower than outdoors, resulting in negative pressure, and outside air flows in through the exhaust stack, causing combustion. To avoid this, a backwind prevention section is installed to allow outside air to escape indoors.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a system in which outside air flowing back from outdoors between a combustion equipment main body installed indoors and an exhaust stack is directed to the combustion equipment main body. In a combustion apparatus in which a headwind outflow part is formed in a headwind prevention part for preventing inflow, a first temperature sensitive means is provided in the headwind prevention part, and a second temperature sensitive means is provided in the vicinity of the headwind outflow part. The detection signals from the first temperature sensitive means and the second temperature sensitive means are used to compare the temperatures in the vicinity of the headwind prevention section and the backwind outflow section, or the detection signals from the second temperature sensitive means are used to compare the temperatures near the backwind outflow section. The indoor exhaust gas leakage is monitored by determining whether the temperature exceeds a predetermined temperature, and if the exhaust gas is leaking indoors, the fuel supply is cut off.

(Function) When the exhaust gas from the combustion appliance is normally discharged, the exhaust gas is discharged outdoors through the backwind prevention section and the exhaust stack. Since the exhaust gas passes near the first temperature sensitive means, the detection signal from the first temperature sensitive means is larger than the detection signal from the second temperature sensitive means.

Now, when the indoor air pressure is lower than the outdoor air pressure and becomes negative pressure, the outside air flows in from the exhaust stack and flows indoors through the backwind outflow part of the backwind prevention part, and the exhaust gas flows indoors with the outside air. leaks to. Therefore, although the temperature near the first temperature sensitive means and the temperature near the second temperature sensitive means in the headflow outflow section are equal, the latter becomes higher in temperature. When such a state is determined to be an abnormal state and the time in this abnormal state reaches a predetermined time, the fuel supply is cut off and combustion is immediately stopped.

Furthermore, if the exhaust pipe is blocked for some reason, the exhaust gas flows indoors through the backflow outflow section because the exhaust path is blocked. In this case, the exhaust gas first stays in the vicinity of the exhaust stack and the headwind prevention part and flows out from the headwind outflow part indoors, so that the temperature in the vicinity of the headwind outflow part exceeds a predetermined temperature. This predetermined temperature is determined by the combustion performance of the combustion appliance and is obtained by measurement. Such a state is considered to be an abnormal state, and when the time in the abnormal state reaches a predetermined time, the fuel supply is cut off and combustion immediately stops.

Further, when the time in the abnormal state mentioned above cumulatively reaches a predetermined time within a certain period of time, the fuel supply is cut off and combustion immediately stops.

In other words, even if exhaust gas backflow occurs from time to time, incomplete combustion will not occur within a predetermined period of time, so there is no need to immediately stop combustion; Combustion is stopped only when it occurs continuously for a certain period of time or when a backflow condition cumulatively occurs for a predetermined amount of time within a certain period of time, making it possible to avoid unnecessary combustion stoppages and prevent practical problems. It becomes something without.

Ru. Therefore, the temperature near the first temperature sensor 14 becomes higher than that near the backflow outflow section 12, and the detection signal related to the exhaust gas temperature by the first temperature sensor 14 is larger than the detection signal by the second temperature sensor 15. When in normal condition,
Combustion continues as it is (see Figure 1).

Further, even if the secondary exhaust pipe 5 is blocked for some reason, the exhaust gas flows indoors through the backflow outflow section 2 because the exhaust path is blocked (see Fig. 3). In this case, the exhaust gas first stays in the vicinity of the secondary exhaust stack 5 and the headwind prevention part 6 and flows out indoors from the headwind outflow part 12, so that the temperature in the vicinity of the headwind outflow part 12 exceeds a predetermined temperature (for example, 100° C.). The control means determines that the exhaust gas is flowing back indoors due to blockage, and when this state reaches a predetermined time, the control means turns off the electric circuit of the solenoid valve 11 to cut off the supply of fuel gas, and immediately stops combustion. Do this.
