とするものである。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a safe combustion device for a gas combustor in a water heater such as an instantaneous gas water heater, a heating water heater, and the like. In this type of conventional gas combustor, the solenoid valve that supplies gas to the main burner is opened after detecting that the pilot burner is ignited, so the solenoid valve is small even when the flame of the pilot burner is small and the main burner is not ignited. There was a case that the unsealed gas was released due to the opening. An object of the present invention is to provide a gas combustor for a water heater provided with a safe combustion device that does not cause such a dangerous state.

In a water heater comprising a main burner and a feed water heating pipe heated by the main burner, a water inlet temperature detector is provided on the water inlet side of the water heater and a hot water outlet temperature detector is provided on the water outlet side. The supply of the fuel gas supplied to the main burner is controlled by a controller for inputting the output of the reactor, and the detection output of the inlet water temperature detector and the detection output of the outlet water temperature detector are the same or different by the controller. When they are close to each other, the gas supply to the main burner is stopped.

Reference numeral 1 is a main burner, 2 is a pilot burner, 3 is a gas supply pipe, 4 is a main solenoid valve, 5 is a solenoid valve for controlling combustion, 6 is an igniter, and 7 is a flame detector. Reference numeral 8 denotes a heat exchanger, which is provided with a water supply heating pipe 9 for entering water in the direction of arrow a and discharging hot water in the direction of arrow b. A water inlet temperature detector 10 for detecting the temperature of the water inlet is provided on the water inlet side of the water supply heating pipe 9, and a hot water outlet temperature detector 11 for detecting the temperature of the hot water outlet is provided on the hot water outlet side. 12 is a flame detector 7, an inlet water temperature detector 10 and an outlet hot water temperature detector 11
Is a controller for controlling the combustion of the burner by inputting the output of. 13 is a power source and 14 is a power switch.

磁弁５のガス供給量を制御する。Next, the operation will be described. When the power switch 14 is turned on, the controller 12 operates to open the main solenoid valve 4 and the gas flows into the pilot burner 2. At the same time, the igniter 6 discharges by the action of the controller 12 and ignites the pilot burner 2. When the flame detector 7 detects the flame of the pilot burner 2, the controller
Reference numeral 12 supplies gas to the main burner 1 using the control solenoid valve 5, and the main burner 1 is ignited. The controller 12 inputs the temperature signals detected by the incoming water temperature detector 10 and the outgoing hot water temperature detector 11, and controls the gas supply amount of the control solenoid valve 5 so that the outgoing hot water temperature becomes constant.

るとメーンバーナ４を閉じてガスの供給を停止する。By the way, the main burner 1 may not be ignited when the pilot flame is short due to the clogging of the nozzle of the pilot burner 2 or the decrease of gas pressure, or due to other reasons, only a part of the main burner is ignited and normal combustion does not occur. It may not be done. In this case, the outlet heated water temperature becomes the same as or close to the inlet water temperature, and when the controller 12 detects this, the main burner 4 is closed and the gas supply is stopped.

効果を有する。As described above, in the safe combustion apparatus of the present invention, when gas is supplied to the main burner but the combustion of the main burner is not normally performed, gas supply is stopped and raw gas is released. It has an excellent effect of preventing the danger of being caused.
