摘要： PROBLEM TO BE SOLVED: To achieve early detection of improper installation environment of an instant water heater. SOLUTION: In this instant water heater in which a heat exchanger comprising a water tube and a fin is arranged above a burner 2 provided in an apparatus body 1 and a louvre-shaped air hole 7 for supply air is formed at lower parts of both sides of the apparatus body 1 while the top surface of the apparatus body 1 forms an exhaust gas port, a temperature sensor 8 is arranged near the inside of the louvre-shaped air hole 7 and the supply of a fuel to the burner 2 is cutoff by an output of the temperature sensor 8. This allows early detection that a flame flows rapidly from the louvre-shaped air hole on the side of the apparatus body in a gale because of improper installation environment of the water heater thereby stopping the supply of a fuel.

摘要： PURPOSE:To safely feed water during the feed of hot water through simple operation, by a method wherein the polarity of a power fed from a constant power source to a solenoid through a circuit for holding an initial opening valve is inverted. CONSTITUTION:In an instantaneous water boiler, a polarity inverting circuit 19A to feed a feed power from a built-in battery 15, being a constant power source, to a first solenoid 12A by inverting a polarity is situated in a circuit 16 for holding an initial opening valve. When, with the polarity inverting circuit 19A operated, the polarity of a feed power from a built-in battery 15 is inverted and the feed power is fed to the first solenoid 12A, the magnetic force of the first solenoid 12A excited by means of the feed power is offset with that of a second solenoid 12B excited by the thermoelectromotive force of a thermocouple 17. Since the self-closing energizing force of a fuel cutoff valve 10 is increased over a magnetic force for holding an opening valve being exerted against the self-closing energizing force, the cutoff valve 10 is closed. Thus, the feed of fuel to a burner 2 is shut off to stop combustion, and water prevented from being heated is fed through a hot water feed passage 5 from a heat exchanger 3.

摘要： PURPOSE:To prevent the generation of a fuel leak and a backfire phenomenon by the cutoff of fuel supply to a burner simple and completely in one operation from the condition of hot water supply by a method wherein at a safety controller delivering a cutoff signal to a fuel supply passage for the burner based on a malfunction detection signal from a malfunction detection sensor, an operation means for water supply delivering false a water supply signal corresponding to the malfunction detection signal is installed. CONSTITUTION:An operation means 19 for water supply is a switch placed in series in a safety circuit 18 connecting a thermocouple 17 with a secondary solenoid 12B. The switch 19 is closed in the condition of hot water supply. When water is required, the power supplied to the solenoid 12B is reduced by opening the switch 19, even if the thermoelectromotive force of the thermocouple 17 is sufficient, the closing operation of a fuel cutoff valve 10 is carried out just as in the occurring time of abnormal condition. The switch 19 is attached on the moving end of an operation device 21 for controlling hot water temp. which can be slided freely along a rail 20.

摘要： PROBLEM TO BE SOLVED: To detect the incomplete combustion of a gas burner more accurately. SOLUTION: This water heater is provided with a relatively high voltage output of thermocouple 3 which detects the combustion state of a gas burner 1, and a relatively low voltage output of heat exchanger 4 which detects the inside temperature of a heat exchanger 2. The output of both thermocouples 3 and 4 is inputted separately into filter circuits 21 and 22 so as to remove higher harmonic components. An operating part 24 seeks the difference being obtained by subtracting the output voltage of the filter circuit 22 from the output voltage of the filter circuit 21. A combustion state judger 24 judges that the gas burner 1 is in incomplete combustion when the output of the operating part 23 becomes smaller than the specified threshold, and shuts off the safety valve 15 supplying the gas burner with fuel gas.
