<p>PROBLEM TO BE SOLVED: To eliminate a disadvantage that a gas appliance using a motor and an electromagnet operated with a power supply from an external commercial power cannot be worked at all at the time of its power failure, ability of cooking is desired in the gas cooking stove, for example, due to continuous supply of gas even under power failure of longer hours, and using a battery cell as an emergency power supply requires a severe consumption of the battery cell due to a continuous energization of electromagnet of a solenoid safety valve during ignition.SOLUTION: A motor is operated with an electrical power of a battery cell to cause a valve body to be opened and under a state of valve opened condition, the valve body is kept in its opened state without energizing an electromagnet.</p> |
