PURPOSE:To enhance safety in case that a person getting warmth from a stove happens to be absent from the kerosene stove when the kerosene stove of wick type is extinguished by the function of a vibration sensor, by sounding an alarm and by indicating extinguishment on an indicator. CONSTITUTION:Cam switches 5 and 6 are closed by the revolution of a motor 8 elevating a wick. A microcomputer 1 is provided with two programs: one of them drives the motor 8 in accordance with the states of cam switches 5 and 6, and the other program stops combustion when it receives a signal from a vibration sensor 7. In the state of steady combustion, the wick is at the top position of rise and the motor 8 is in the stopped state. When the vibration sensor is vibrated during combustion and an extinguishment signal is input in the microcomputer 1, the motor 8 in a halt is started again and the wick is lower by the motor until combustion is stopped, and at the same time an alarm 9 starts sounding, and extinguishment is indicated on an indicator 10. |
