Abstract (en)
A controlling method for controlling a solenoid valve that has a multi-stage valve, and the multi-stage valve takes a preset time to go from fully close to fully open. The controlling method including: proceeding with an ignition procedure for providing a power supply to the solenoid valve and counting up to a first default time. When the provision time of the power supply to the solenoid valve reaches the first default time, and a sensing signal indicates an extinguishing state, then interrupting the power supply to the solenoid valve. When the interruption time for the power supply reaches a second default time, then restore the power supply to the solenoid valve and re-count up to the first default time. Therein, the sum of the first default time and the second default time is smaller than the preset time. Therefore, a geyser that utilizes the solenoid valve may increase in safety.
