It was a shame that they did not check to see if the fire had been extinguished, as it would have been a nuisance. Although rare, embers can cause the combustor to overheat abnormally, causing an explosion and a fire. Therefore, it is necessary to confirm that the fire has been extinguished, and a fire extinguish confirmation device is important for safe use. It is expected that various devices will be installed in the future.

is the core, and 6 and 7 are the outer flame tube and inner flame tube that make up the burner. The upper end of the wick 1 protrudes from the wick guide path 4 during a combustion operation and burns the oil sucked up by capillary force, while it sinks into the wick guide path 4 during a fire extinguishing operation to cut off the air supply and prevent the combustion of oil. extinguish the fire. The embers after the extinguishing operation are present at the upper end of the wick 1 submerged in the wick guide path 4, and slowly burn at the upper end of the wick 1 during the extinguishing operation shown in FIG. In order to detect the slowly burning flames of the embers, a peephole 8 is provided in the wick outer cylinder 2 at the upper end of the wick 1 during extinguishing operation, and a peephole 8 is provided in the wick outer tube 2 to block the peephole 8. For example, the patent application in 1983-
Color sensor 10 as disclosed in No. 73868
, the light receiving surface of the color sensor 10 is located at the peep hole 8.
It is placed so as to face the 11,11...
These holes supply combustion air to the upper end of the core during combustion operation, and are provided at equal intervals on the upper peripheral wall of the outer core cylinder 2. 12 is a sensor cover that prevents the color sensor 10 from malfunctioning due to external light, and a sensor cooling cover that cools the sensor 10 with combustion air supplied to the upper end of the wick through the hole 11 during combustion operation. It forms an air passage 13.

DC is a direct current power source, and the ignition battery of the oil combustor is also used as a power source. Light emitting element LED and comparator IC with compensation resistor R3 on DC power supply DC
Further, the input terminal of the comparator IC is connected to the color sensor output terminal of the circuit including the color sensor 10 connected to the DC power supply DC and the load resistors R 1 and R 2 . In this circuit, the short circuit currents I 1 and I 2 obtained from the two photodiodes PD 1 and PD 2 constituting the color sensor 10 are
The voltages are converted into voltages V 1 and V 2 by load resistors R 1 and R 2 connected in series with PD 2 . These voltages V 1 and V 2 are
These are input to the input terminal and input terminal of the comparator IC, respectively. When the color sensor 10 receives light from the flame of the ember that has sunk into the wick guide path 4 and is slowly burning at the upper end of the wick 1 due to lack of oxygen,
The relationship of V 1 > V 2 is established depending on the settings of the load resistances R 1 and R 2 . When the comparator IC receives an input of V 1 >V 2 , the output changes from a "high" level to a "low" level, forming a circuit that lights up the light emitting element LED.

を確認することができる。 Next, the operation of extinguishing detection will be explained. When you operate the fire extinguishing lever etc. to extinguish the fire, wick 1
The core 1 is sunk into the core guide path 4 as shown in FIG.
The embers start to burn slowly at the top end. The color sensor 10 detects the flame of this ember and changes the output of the comparator 10 shown in FIG. 2 from the "high" level to the "low" level to light up the light emitting element LED. When the embers are extinguished, the output of the comparator 10 changes from "low" level to "high" level, turning off the light emitting element LED.
Also, during combustion operation, the wick 1 rises and closes the peephole 8, so that almost no light enters the color sensor 10, and the visible light from the burner is blocked by the sensor cover 12 and does not enter the light emitting element LED. remains off. Therefore, the light emitting element turned on after the fire extinguishing operation
Extinguishing of the embers at the upper end of the wick 1 can be confirmed by turning off the LED.

により有効である。 In addition, when the DC power source is also used as an ignition battery (for example) 3V, the battery voltage is the ignition limit voltage (for example
The above circuit can also be used as a battery checker by setting the compensation resistor R3 so that the light emitting element LED does not light up when the voltage drops to 2.4 v ). On the other hand, if another battery checker is incorporated into the above circuit, malfunctions of the color sensor 10 due to battery consumption can be discovered before they occur, which is more effective for safe use.
