Because the kerosene that has risen due to the action is vaporized and burned by the heat of the combustion tube 4,
To stop combustion, move the lever 5 integrated with the wick 3 downward to move the wick 3 away from the combustion tube 4 and minimize the vaporization of kerosene, at the same time stopping the air supply to the wick 3. had achieved it.

の最大欠点とされるものである。Problems to be Solved by the Invention However, with the above configuration, even if the lamp wick 3 is lowered with the lever 5, the vaporization of the kerosene does not stop immediately due to the heat capacity of the surrounding area, and furthermore, the combustion tube is also heated. Because of this, the vaporized gas comes into contact with the combustion tube and heats it up, causing it to deteriorate and emit a foul odor, which is considered to be the biggest drawback of kerosene stoves.

It should be increased proportionately.
作 用
本発明は上記した構成によつて、灯油を気化素

快適な暖房を得られるようになるのである。Effects The present invention has the above-described configuration, which allows the amount of kerosene contained in the vaporization element to be extremely small because the kerosene is fed to the vaporization element using a fuel pump.
When the fuel pump is stopped, the supply of kerosene immediately stops, and combustion stops without changing the vaporization status of the vaporizing element, so there is no vaporization of kerosene after combustion stops like in the wick type, and therefore there is no foul odor. This means that you will be able to enjoy comfortable heating without causing any problems.

を高くするように設計されている。 FIG. 3 shows an embodiment of a refueling pump 7 using a bimorph element, which has a suction port 20 and a discharge port 21 provided in a pump body 19.
is connected to the oil pipe 8. A check valve 22 is provided at the suction port 21, and a check valve 23 is provided at the discharge port 21, and these are communicated with each other through a pump chamber 24.
A bimorph element 26 is installed facing the pump chamber 24 and fixed to the pump body 19 with a sealing material 25. By applying an alternating current voltage to the bimorph element 26, the volume of the pump chamber 24 is increased by the bending movement of the bimorph element 26. It increases and decreases, and this volume change is rectified by check valves 22 and 23 to perform a pumping action. The alternating current voltage is produced according to the principle shown in the block diagram of FIG. The voltage of the battery 27 is increased to a predetermined value by a booster circuit 28, converted into an AC voltage signal by an oscillator 29, and then adjusted by a voltage amplifier 30 to obtain a desired voltage value. The voltage value to be adjusted is commanded by the amplification rate regulator 31. The signal 32 from the temperature sensor 17 is sent to the amplification rate regulator 31.
The voltage applied to the bimorph element 26 is adjusted according to the temperature of the combustion tube 4. Although this may vary depending on the circuit settings, the present invention is designed to lower the voltage of the bimorph element 26 and reduce the pump flow rate when the temperature is low, and to increase the voltage when the temperature rises.
給油ポンプ７の流量と燃焼筒４の温度との関係
は、第５図で示すように設定される。 The relationship between the flow rate of the fuel pump 7 and the temperature of the combustion cylinder 4 is set as shown in FIG.

さないように設定されるのである。 When the switch 33 is turned on, the bimorph element 24
An alternating current voltage is applied to the fuel supply pump 7, which operates to suck up kerosene from the kerosene tank 1 and send it to the vaporizing element 10. Since the vaporizing element 10 is made of a material having pores, kerosene oozes out from the oil supply groove 12 over the entire circumference of the vaporizing element 10. When the vaporizing element 10 is heated by the igniter 16, the kerosene is vaporized and ignited, and the entire vaporizing element 10 is ignited and combustion begins. At this time, if the amount of kerosene from the fuel pump 7 is too large, unvaporized kerosene overflows and cools the vaporizing element 10, causing the fire to go out.
Therefore, when the temperature sensor 17 does not raise the temperature of the combustion cylinder 4, it instructs the fuel pump 7 to send the temperature T1 and the minimum flow rate G1 at the time of ignition, as shown in FIG. As combustion progresses, the temperature of the combustion tube 4 rises, and the temperature of the vaporizing element 10 itself also rises, so vaporization is promoted and vaporization progresses even if a large amount of kerosene is sent. Then, the temperature of the temperature sensor 17 also rises, so the flow rate of the oil supply pump 7 is increased proportionally as shown in FIG. 5 to match the vaporization flow rate. When the combustion cylinder temperature reaches the set temperature T2 , the oil supply pump 7
The flow rate is controlled by Q 2 and set to prevent abnormal temperature rise.

を完結する。すなわち灯油は気化を完了するまで
燃焼し、燃焼をしない気化灯油は発生しないので
ある。 In this state, when the switch 33 is turned off, the oil supply from the oil supply pump 7 is immediately stopped. Since the temperature of the combustion tube 4 has been sufficiently warmed, the kerosene contained in the vaporization element 10 is sufficiently vaporized and combustion is completed in a short time. In other words, kerosene burns until it completes vaporization, and vaporized kerosene that does not burn is not generated.

位置を変化して消火する必要がなく、燃焼を停止
する場合、灯油の気化が停止するまで燃焼が持続
し、燃焼しない未燃灯油ガスが出ることがないか
ら悪臭の発生が皆無になる。Effects of the invention: Since kerosene can be forcibly sent to and stopped from the vaporizing element using a fuel pump, there is no need to change the position of the vaporizing element to extinguish the fire, and when stopping combustion, the vaporization of kerosene is Combustion continues until it stops, and as no unburned kerosene gas is released, there is no odor.
さらに灯油を強制的に送る場合に発生する気化
量と送油量のアンバランスによる失化（火が消え
る）は、燃焼筒の温度に応じて送油量を変化させ
ているので、気化量が小さい着火時にも問題を発
生しない。 Furthermore, when kerosene is forcibly sent, the amount of vaporized oil is changed due to an imbalance between the amount of vaporized oil and the amount of oil sent (the flame goes out). No problems occur even when a small ignition occurs.

Portability can be ensured.
