本発明は、灯芯式等の石油燃焼器の吸臭制御装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an odor absorption control device for a wick-type oil combustor or the like.
従来の技術
一般に灯芯式石油燃焼器は、灯芯を降下させて消火する
と、この灯芯から気化し続ける石油蒸気が、いままでの
燃焼で高温になっている燃焼筒内に入り、ここで熱分解
されて強い臭気を発生するという問題があった。Conventional technology In general, in a wick-type oil combustor, when the wick is lowered to extinguish the fire, the petroleum vapor that continues to vaporize from the wick enters the combustion cylinder, which has become hot due to previous combustion, where it is thermally decomposed. There was a problem in that it generated a strong odor.
そこで最、近では、この消火時の臭気を低減するために
消火と同時にファン等の吸臭装置を作動させ、灯芯から
気化し続ける石油蒸気をタンク内に吸い込んだ後、外部
へ放出するものが提案されている。Recently, a proposal has been made to reduce the odor caused by extinguishing a fire by activating an odor absorbing device such as a fan at the same time as the extinguishment, sucking the petroleum vapor that continues to evaporate from the wick into the tank, and then releasing it to the outside. has been done.
第４図、第５図は、このような装置を右する灯芯式石油
燃焼器で、灯芯ｌを降下させて消火すると吸臭装置２の
ファン３が回転を始め、灯芯１上部から気化し続ける石
油蒸気をタンク４内へと、吸引し排出口５より外部へと
放出する。Figures 4 and 5 show a wick-type oil combustor that uses such a device. When the wick l is lowered to extinguish the fire, the fan 3 of the odor absorbing device 2 starts rotating, and the oil continues to vaporize from the top of the wick 1. Steam is sucked into the tank 4 and released to the outside from the outlet 5.
この吸臭装置付きの灯芯式石油燃焼器によれば消火後に
灯芯から気化し続ける石油蒸気が高温の燃焼筒６へと流
れ込まず、タンク４内を介して大気中へ放出されるので
石油蒸気が熱分解されることによって生じる臭気を低減
することができる。According to this wick-type oil combustor with an odor absorbing device, the oil vapor that continues to vaporize from the wick after extinguishing does not flow into the high-temperature combustion tube 6, but is released into the atmosphere through the tank 4, so the oil vapor heats up. Odors caused by decomposition can be reduced.
このような灯芯式石油燃焼器の吸臭装置の制御装置は従
来第６図のように構成されていた。A control device for such an odor absorbing device for a wick-type oil combustor has conventionally been constructed as shown in FIG.
以下その構成と動作を説明する。先ず灯芯上下ツマミ７
を操作して灯芯１を上昇させて点火すると、灯芯上下ツ
マミ７と連動するスイッチ８の常閉接点８ｂを通して、
コンデンサ２６は充電される。The configuration and operation will be explained below. First, turn the wick upper and lower knobs 7.
When the lamp wick 1 is raised and ignited by operating the wick 1, the light passes through the normally closed contact 8b of the switch 8 which is linked to the wick upper and lower knobs 7.
Capacitor 26 is charged.

になる。Next, from this state, operate the wick upper and lower knobs 7 to
When the switch 8 is lowered and extinguished, the normally closed contact 8c of the switch 8 becomes O.
NL, the capacitor 26 is discharged via the transistor 13, the resistor 9, and the switch 8. This discharge current causes transistor 13 to ONL, and transistor 2 to ONL via resistor 21.
3 turns on. As a result, the motor 24 operates, the fan 3 starts rotating, and petroleum vapor is sucked into the tank 4.

ている。Further, when the transistor 13 is turned on, a base current is supplied to the transistor 14 via the resistor 17.16, and the transistor 14 is turned on. As a result, transistor 1
3, the base current continues to flow through the transistor 14 even when the discharge current of the capacitor 26 disappears. At the same time, charging of the capacitor 19 is started via the resistor 18, and when the charging voltage reaches the emitter potential of the transistor 20 or higher, the transistor 20 is turned on. As a result, the transistor 14 becomes 0FFL, and the transistor 13
is also turned off. Further, the power supply to the transistor 23 is also stopped, so it is turned off. Further, since the power supply to the transistor 23 is also stopped, the transistor 23 is in an OFF state, and the operation of the motor 24 is stopped and the rotation of the fan is stopped. That is, the motor 24 rotates to perform the odor absorbing operation while the capacitor 19 is charged to a certain voltage, and then automatically stops.

In order to obtain a sufficient odor absorption effect, the optimal motor rotation speed for odor absorption must be set at the lower limit of the battery voltage, and while the battery voltage is higher than this, the motor must be driven at a higher rotation speed than necessary. This poses the problem of wasting battery energy and increasing noise.

The purpose is to reduce noise and extend battery life by controlling the motor rotation speed to remain constant even when battery voltage changes, and by always driving the motor at the optimum rotation speed for odor absorption. It is.
