Abstract

PURPOSE: To prevent an oxygen deficiency accident from occurring by a method wherein a timer function for measuring the operating time of the water heater is provided so as to forcibly stop combustion when the heater has continuously been used for a predetermined period of time.
CONSTITUTION: When a hot-water supply cock is opend to allow water to flow, a water-pressure responsive valve closes a switch 2 to bring a controlling circuit into operation. That is, a capacitor 3 is first charged through a resistance 6, so that the voltage at an input 21b of a comparator 21 increases gradually and the output 21e changes from LOW to HIGH when the voltage surpasses that at an input 21a. As a resuslt, charging of a capacitor 4 is started, and then comparators 22, 23 are operated in a similar manner. In this case, when the voltage at an input 23a of a comparator 23 becomes higher than that at an input 23b, the output 23e of the comparator 23 changes from HIGH to LOW, thereby turning on a light-emitting diode 16 and operating a buzzer 17. A relay 18 opens a series circuit of a thermocouple 19 and a thermo-valve 20, thereby stopping the combustion operation.
