ことがあり、生ガスが出たままになり、非常に危険であ
るという欠点があった。Conventional configuration and its problems Conventional gas water heaters do not detect that the main burner has ignited, so if the pilot burner nozzle is clogged or the gas pressure is low, the flame in the pilot burner is small and the flame ignites. Although it is detected, the main burner may not ignite, leaving raw gas coming out, which is extremely dangerous.

る。Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks. By detecting with a thermistor that the outlet temperature does not rise, it detects that the main burner is not ignited, and closes the valve to supply gas to the main burner. The purpose is to prevent raw gas from continuing to come out by cutting off the supply of gas.

It has the effect of preventing.
実施例の説明
以下、本発明の一実施例について、図面に基づいて説明
する。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.
第２図に器具の構成を第３図に制御装置の構成を示す。FIG. 2 shows the configuration of the instrument, and FIG. 3 shows the configuration of the control device.

なるように電磁弁２の開度を調節し、メインバーナ３に
流れるガス流量を調節する。When the switch 4 is turned on, the solenoid valve 7 is opened by the microcomputer 6 inside the control device 5, and gas flows into the pilot burner 1. At the same time, the ignition device 8 is discharged by the microcomputer (hereinafter referred to as microcomputer) 6, and the pilot bar 1 is ignited. Then, the flame detection device 9 confirms that the pilot burner 1 has been ignited, and the microcomputer 6 opens the solenoid valve B2 to allow gas to flow into the main burner 3, thereby igniting the main burner 3. The heat exchanger 10 is then heated to warm the flowing water. Then, the temperature of the tapped water is detected by the thermistor 11, and the opening degree of the electromagnetic valve 2 is adjusted by the microcomputer 6 so that the tapped water temperature is constant, and the flow rate of gas flowing into the main burner 3 is adjusted.

現象があった。As shown in the operation flowchart of the conventional example in Fig. 1, in the conventional method, after detecting that the pilot burner 1 has been ignited, the solenoid valve 2 is opened and gas flows to the main burner 3, and the main burner 3 is actually ignited. It was not possible to detect whether it was done or not. Therefore, pilot burner 1
If there is a defect in the flame transfer from the main burner 3 to the main burner 3, there is a very dangerous phenomenon in which raw gas continues to come out from the main burner 3.

If not, close solenoid valve 7 and solenoid valve 2 and garbage.
