Title: Device for controlling odor-absorption for kerosene burner
Inventor: TAKIGUCHI MASAHIRO
IPC: F23D3/18
Filed: 1989-07-28
Abstract: PURPOSE:To reduce the noise and extend the life of a battery by controlling a motor at a constant number of revolutions independent of changes in the voltage of the battery so as to run the motor constantly at an optimum rate for absorption of the odor. CONSTITUTION:An extinguishment switch 32 detects extinguishment of fire; a motor thereupon is started and continuously run for a time set by a timer circuit 55 and then stopped by the control. By means of a duty-control circuit 57 the application of the voltage of a battery to the motor 46 is turned on and, every time the potential of a capacitor 47 reaches a specified voltage, the voltage of the battery is withheld from application to the motor 46 for a certain period. The time required for the potential of the capacitor 47 to reach the specified voltage is shorter when the battery voltage is higher and longer when the battery voltage is lower. This method keeps the number of revolutions of the motor unaffected by changes in the voltage of the battery. The revolution of the motor 46 is automatically stopped when the potential of the capacitor 35 falls to the threshold of a NOR gate circuit 33a.
