体ケース、3はバーナ、4は燃焼筒である。This may result in an increase in concentration, which is unfavorable from a sanitary standpoint, and may even pose a threat to human life. Furthermore, kerosene stoves tend to generate odor and Co due to incomplete combustion, which poses a problem in terms of comfort. For this reason, we try to ventilate the room by driving the ventilation fan installed on the wall of the room or by periodically opening and closing windows and doors, but sometimes the ventilation is insufficient, and we have to operate the ventilation fan and combustor separately. There were problems with usage, such as the need for Furthermore, the ventilation fan is driven in conjunction with the operation of the combustor, but it is not controlled in accordance with the actual situation. The present invention aims to solve these problems, and one embodiment of the present invention will be described below with reference to the accompanying drawings. 1st

す一例である。Figure 2 shows the indoor 00% concentration of Co at the 4th outlet of the combustion tube when an open combustor is burned in a nearly sealed room.
This is an example showing changes in the amount of flame generated (PPM) and the flame resistance value (MΩ) as an output when a flame rod is used as the flame detector 8.

COの発生量が少なくてすむと言える。Therefore, in the present invention, as shown at point A in FIG. 2, the flame resistance value of the flame detector 8 is 10r! When the resistance reaches 4Ω, the controller 7 stops combustion in the burner 3 and starts driving the ventilation fan 17. Another method is to use the ventilation fan 17 when the flame resistance value is around Ω at point B.
The aim is to reduce indoor CO and increase 02 concentration through ventilation, thereby increasing flame resistance. When the value returns to around Ω, the ventilation fan 17 is stopped, and in the case of incomplete combustion where the flame resistance value continues to rise even with this operation, when the flame resistance value reaches, for example, 10 MΩ, the burner 3 control to stop. Also, from Figure 2, the flame resistance level at which burner 3 is stopped is set to normal (0220
It can be said that the amount of CO generated can be reduced by setting it to a value slightly higher than 21%), for example, 2 to Ω.

効果を奏する。However, as shown in FIG. 3, the flame resistance does not drop to the stable level instantaneously after the burner 3 is ignited at 2, and it takes 1 to 2 minutes. This is due to the instability of the flame during ignition and the delay in temperature rise of the flame rod. In reality, flame detection control is performed approximately seconds after ignition, so in order to prevent malfunction, the level of flame resistance value at which burner 3 is stopped should be given a considerable margin compared to the normal level. There is a need. As described above, the present invention uses a flame detector using a flame rod or the like to detect the burner of the combustor and the ventilation fan 3. The following effects can be achieved by interlocking and controlling the following.
(1)室内開放形燃焼器と換気扇を連動させ、しかもこ
れらを燃焼器の火炎検知器によつて停止、駆動制御する
ようにしたので密閉室内での使用時やバーナのトラブル
などによる不完全燃焼時には確実に換気が行なわれ人命
事故を防止できかつ操作も簡単になる。(1) The indoor open combustor and ventilation fan are linked, and these are stopped and driven by the combustor's flame detector, so incomplete combustion may occur when used in a closed room or due to burner trouble. Ventilation can sometimes be reliably performed, preventing accidents that could cause loss of life, and making operation easier.
(2)燃焼火炎の異常時、火炎検知器によつてバーナの
燃焼を停止すると同時に換気扇を駆動するようにすれば
すみやかに室内のCOなどの有害成分を排出し、02濃
度を高めることができる。(2) When there is an abnormality in the combustion flame, if a flame detector is used to stop combustion in the burner and at the same time drive a ventilation fan, harmful components such as CO in the room can be quickly exhausted and the 02 concentration can be increased. .
(3)火炎検知器の火炎抵抗値などの変化を2段階に分
けて検出し、バーナの燃焼停止制御よりも先に換気扇を
駆動させれば、著しい不完全燃焼状態に至る前に換気が
行なわれ安全性が高まると同時に安定した燃焼を継続す
ることができる。(3) By detecting changes in the flame resistance value etc. of the flame detector in two stages and driving the ventilation fan before the burner combustion stop control, ventilation can be performed before a state of extremely incomplete combustion occurs. This increases safety and at the same time allows stable combustion to continue.
また着火時火炎抵抗値が減少し定常レベルに達するのに
時間を要することを利用し着火してから約1分間換気扇

気やCOを室外に排出することから快適性を高めること
ができる。Furthermore, by taking advantage of the fact that the flame resistance value decreases upon ignition and takes time to reach a steady level, the ventilation fan can be driven for approximately one minute after ignition. Therefore, the odor and CO generated at the time of ignition are discharged outside, thereby improving comfort.
