ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kerosene stove that burns oil using a lamp wick.In particular, it detects deterioration of the usage environment due to combustion, such as a decrease in oxygen concentration or an increase in carbon monoxide concentration, and detects the problem caused by oxygen deficiency. The purpose is to prevent accidents from occurring.

る。 Figure 1 is a perspective view of a general kerosene stove.
Inside the exterior 1 is a reflector 2, and in the center of its curved surface is a combustion tube 3. By burning the oil (kerosene) sucked up into the wick inside the reflection plate 2, the combustion tube 3 becomes red hot, and the heat is released. The reflector plate 2 applies radiant heat or reflected heat to the front of the stove for heating. The knob 4 is used to move the wick up and down, and when raised upward, a button 5 is pressed to ignite the wick and start combustion. Furthermore, when the other knob 25 is pushed downward, the knob 4 is unlocked, and when the knob 4 returns to its original position, the wick inside the combustion tube 3 also goes down and extinguishes the fire.

つて非常に危険である。 Oil stoves with this type of structure consume oxygen in the environment in which they are used, and if the supply of oxygen from each part is low, the oxygen concentration will gradually decrease, and as a result, carbon monoxide produced by combustion will also increase. . In such cases, it is necessary to sufficiently ventilate the room because it has a negative effect on the human body, and the user consciously opens the window at regular intervals to let in fresh air. However, if this ventilation is neglected, the oxygen concentration will decrease and carbon monoxide will increase, creating a so-called oxygen-deficient condition, which is extremely dangerous.

い。 Therefore, it is necessary to provide a kerosene stove that detects such a state and issues an alarm or automatically stops combustion. In order to provide such a kerosene stove, an oxygen deficiency sensor that detects the decrease in oxygen concentration or increase in carbon monoxide is required. Although various types of oxygen deficiency sensor can be considered, it is most preferable to use an element that detects the above-mentioned oxygen concentration, oxygen partial pressure, or carbon monoxide. This is because it detects oxygen deficiency conditions directly rather than indirectly, which has a significant advantage in terms of reliability. However, such an element does not exhibit its performance unless maintained at a certain temperature or higher, and has the characteristic that it also responds to temperature changes. Figures 2A and 2B show its characteristics. For example, when using a tin oxide-based element, when the temperature is held constant, the resistance value changes depending on the oxygen concentration and remains the same, as shown in Figure 2A. As shown in Figure B, even if the oxygen concentration is approximately constant, when the temperature changes, the resistance value changes as in the case of oxygen deficiency. Therefore, when installing an oxygen deficiency sensor in the above-mentioned kerosene stove, this point must be fully taken into consideration.

備えた石油ストーブを提供することができる。 The present invention is an oxygen deficiency sensor that satisfies the above conditions and has sufficient heat resistance, and in order to ensure a satisfactory lifespan, the oxygen deficiency sensor is first provided on the bottom surface of the top plate above the combustion cylinder, and The sensor is characterized by being placed in a container with a downward opening. With this configuration, the oxygen deficiency sensor is always maintained at a high temperature above a certain value, and because it is an open-air combustor, it is a highly reliable oxygen sensor that is almost unaffected by temperature changes caused by wind flow, etc. It is possible to provide a kerosene stove equipped with a safety function for detecting absence.

の説明を行う。 Additionally, kerosene heaters are generally easy to use because they do not have power cords, and therefore they are easy to carry anywhere. Of course, there are cases where a blower fan is attached to blow air and use it as hot air, but most of them are portable (hereinafter referred to as portable).
It is. Therefore, an embodiment of the present invention will be explained based on a case where a dry battery (direct current of several volts) is used as a power source.

圧を制御回路１７の全体に供給するものである。 In a portable stove with such a configuration, a well-known oxygen deficiency sensor 14 for detecting at least one of oxygen concentration, oxygen partial pressure, or carbon monoxide concentration is installed in the upper case 15 on the center line of the combustion tube 3.
The lead wire 16 reaches the control circuit 17 through a place where the temperature is not very high. A voltage is supplied to the control circuit 17 from the dry cell battery 7 through another lead wire 18 . On the other hand, when the rotary knob 4 is rotated and the lamp wick 6 is pushed upward, a cam 19 coaxial with the rotary knob 4 operates the micro switch 20 in conjunction with the operation of the knob 4. This microswitch 20 supplies the voltage of the dry battery 7 to the entire control circuit 17.

送る。 First, the general operation of the above configuration will be explained. First, turn the rotary knob 4 and lift the wick 6 upward. (FIG. 3 shows the state in which it has already been raised.) At the same time, the micro switch 20 is closed by the cam 19, and the control circuit 17 shown in FIG.
Apply voltage to enter the oxygen deficiency detection state. In this state, press the button 5 to bring the ignition heater 9 close to the lamp wick 6, and press the switch 8 to bring the dry battery 7
The voltage is passed through the heater 9 to ignite it. When you release your hand after ignition, button 5 returns to its original position. In this way, the petroleum (light wick) vaporized from the lamp wick 6 is normally combusted by the inner cylinder 12, outer cylinder 13, etc. The burned heat is reflected by the reflector plate 2 and transmitted to the front surface, and the increased amount is sent to the oxygen deficiency sensor 14.
The heat reaches the inside of the case 15 where there is heat, and heat is accumulated inside the case 15. At the same time, oxygen, carbon monoxide, etc. in the air contained in the combustion flame are also sent into the case 15, so the oxygen deficiency sensor 14, which operates at 500 to 600°C, constantly monitors the combustion state and sends a signal to the control circuit 17. send.

ことにより酸欠を未然に防止できる。 If the amount of oxygen in the air decreases to, for example, 18%, then carbon monoxide increases and the resistance value of the oxygen deficiency sensor 14 decreases, the transistor 23 becomes conductive via the comparator 22, and the fourth A buzzer 24 shown in the figure sounds to issue an alarm. At this point, the user can prevent oxygen deficiency by opening the window or stopping combustion.

ようになる。 Another 0.5 if you didn't notice it at this point.
When the oxygen concentration decreases by ~1.0%, the transistor 26 becomes conductive via the comparator 25, and the solenoid 27 operates, causing the pendulum (see Fig. 4) to operate in the same manner as when vibrating, and locking the knob gear 29. and return everything to its original position (extinguished state).
ここで上記ケース１５は燃焼により上昇する燃
焼ガスＢをそのまゝケース１５の中に受け入れ酸
欠センサ１４の温度をその動作が正しく動作する
温度約500〜600℃に保つ。 Here, the case 15 receives the combustion gas B rising due to combustion into the case 15 as it is, and maintains the temperature of the oxygen deficiency sensor 14 at about 500 to 600 DEG C. at which it can operate properly.
第５図はこの酸欠センサの収納するケース１５

ものとしてある。 Figure 5 shows case 15 in which this oxygen deficiency sensor is stored.
This is a detailed explanation of the state of oxygen deficiency sensor 14.
is located approximately at the center of the case 15, and the case wall is made of a metal material or the like to have as large a heat capacity as possible.

である。 The reason why such a case 15 is used is to keep the temperature of the oxygen deficiency sensor 14 constant using the high-temperature combustion gas B generated by the combustion flame.If such a case 15 does not exist, air from outside is used. When C enters the sensor, the temperature of the atmosphere around the oxygen deficiency sensor 14 fluctuates, causing malfunctions, but with the case 15, such occurrences are almost eliminated. In particular, in this embodiment, the maximum opening dimension of the case 15 is made smaller than the maximum diameter of the combustion tube 3, so that the opening of the case 15 is located in the rising region of the combustion gas B, as indicated by arrow C. This is effective because it prevents air from entering.

らに種々の形状のものが考えられるが、上記条件
を満足するものであれば特に限定されない。 Further, this case 15 is configured so that only the lower part facing the combustion tube 3 is opened and all other parts are closed, so that the combustion gas that enters as shown by arrow B is reversed as shown by arrow B' and continues to flow. They are starting to be replaced. In this case 15, it is sufficient that the combustion gas is accumulated for a certain period of time and replaced one after another. Therefore, even if there is a hole near the ceiling 21, the combustion gas B can be accumulated for a certain period of time. There is no problem if the hole is The speed of this exchange of combustion gas is affected by the size of the blockage other than the lower part, and according to experimental results, the most suitable one is the opening area of 2. A square case of about 2 to 2 cm2 (this may also be a round case) and a depth of about 2 to 4 cm is suitable. This is also effective in preventing air C from entering. Note that the case 15 may have various shapes, but is not particularly limited as long as it satisfies the above conditions.

る。 As is clear from the above description of the embodiments, according to the present invention, it is possible to detect a change in usage conditions, that is, an oxygen deficiency state, and issue an alarm or automatically stop combustion, thereby preventing accidents caused by oxygen deficiency. Not only can this be prevented, but even if the combustion part is open to the atmosphere and susceptible to cooling effects such as wind, it accurately detects oxygen deficiency conditions, so there is almost no risk of malfunction. . In particular, in the present invention, the combustion gas is retained in the container to maintain the oxygen deficiency detection element at a high temperature while preventing crosswinds from entering from the front, and to raise the oxygen concentration as the combustion gas rises from the combustion tube. Its effects include preventing indoor air from entering the room and preventing fluctuations in the oxygen deficiency level, and combined with the use of an element that directly detects oxygen deficiency conditions, the reliability is extremely high. There is something big about it.
