らの汚染を未然に防止するものである。(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 sashes, etc., houses have become airtight, and if 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. For example, when a ventilation fan in a kitchen or the like is turned on, a negative pressure is created in the room, and exhaust gas flows back into the room and contaminates the room. In such a case, the present invention immediately and automatically stops combustion in the combustion appliance, thereby preventing pollution from indoor exhaust gas.

断する構戒である。８は邪魔板である。(Structure of the Invention) Reference numeral 1 denotes an exhaust flue near the backwind prevention device 3 of the combustion appliance 2, and a flapper 4 is provided in this flue 1, and when a headwind occurs, the flapper 4 is operated by the headwind. The proximity switch 5 is operated by the operation of the flapper 4 to obtain a detection signal, and this detection signal turns off the circuit of the solenoid valve 6 and cuts off the supply of fuel gas to the burner 7. be. 8 is a baffle plate.

である。At this time, air is flowing in from the backflow outlet 9 as shown by the arrow. FIG. 2(B) shows a state in which exhaust gas flows backward. If there is a backflow of exhaust gas, the flapper 4 rotates as shown by the arrow in the figure, turning on the proximity switch 5. As a result, a detection signal is obtained, and this detection signal turns off the electric circuit of the solenoid valve 6, thereby cutting off the supply of fuel gas.

できる一大利点がある。(Effects of the Invention) As described above, the present invention installs a flapper in the flue near the backwind prevention device, obtains an exhaust gas detection signal by the operation of the flapper, and closes the solenoid valve based on the detection signal. This configuration has the great advantage of being able to instantly stop the flow of fuel gas at the same time as the backflow of exhaust gas, thereby preventing danger.
