本発明はガス、石油等を燃料とする開放燃焼型温風暖房
器において、室内の排ガス濃度により燃焼を停止する制
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 a control device for stopping combustion depending on the indoor exhaust gas concentration in an open combustion hot air heater using gas, oil, etc. as fuel.
従来の技術
ファンヒータ等の燃焼式温風暖房器は室内で燃焼するた
め室内空気の換気は不可欠である。従来は酸素濃度の低
下によりネ完全燃焼知至った場合に、バーナ火炎に挿入
したフレームロッドにより、炎のイオン電流の変化を検
出して燃焼を停止するものが一般的であった。Conventional combustion type hot air heaters such as fan heaters burn inside the room, so ventilation of the indoor air is essential. Conventionally, when complete combustion was detected due to a decrease in oxygen concentration, a flame rod inserted into the burner flame was used to detect changes in the ionic current of the flame and stop combustion.

で検出する。For example, there is Japanese Patent Laid-Open No. 59-145422, and this configuration is explained in FIG. The fuel gas is ejected through a nozzle 1, mixed with air through a mixing tube 2, and is combusted by forming an inner flame 5 inside a combustion plate 3 formed of a wire mesh. 6 is flame 5
A DC power source 7 is applied between the flame rod inserted inside and the combustion plate 3, and the ionic current f of the flame is passed through a resistor 8.

Ｉｆが相対値で７以上となった時にバーナの燃焼を停止
し、Ｃ○による中毒事故等の危険を防ぐよって働く。The voltage drop across the resistor 80 is proportional to the flame current I, and when this output is below or below a certain threshold, it is determined that the burner is experiencing abnormal combustion, the fuel supply is stopped, and the fire is extinguished. This characteristic is shown in Figure 7.The horizontal axis shows the indoor oxygen concentration, and the vertical axis shows the flame current If and carbon monoxide (C○) generated from the burner in relative values. As the flame current 1i decreases, the flame current 1i increases. (It may decrease depending on the design of the burner.) At the same time, the burner becomes incompletely combusted and CO begins to be generated.Here, the flame current If becomes 7 in relative value. When this happens, the burner stops burning to prevent dangers such as accidents caused by C○ poisoning.
発明が解決しようとする問題点

炎電流Ｉｆが確実に変化する事を前提条件として成立す

となシＣＯが発生した場合は検出できない。また第７図
で炎電流Ｉｆが６付近で停滞している場合は異常燃焼で
はないがＣ○は室内に累積されていくことも考えられる
。Problems to be Solved by the Invention However, the conventional means as described above is established on the premise that the flame current If changes reliably during abnormal combustion.For example, in FIG.
Even if some parts of the rod 6 are in normal combustion, abnormal combustion occurs in parts other than the rod 6, and if CO is generated, it cannot be detected. In addition, if the flame current If is stagnant at around 6 in FIG. 7, it is not abnormal combustion, but it is possible that C○ is being accumulated in the room.
これ等最悪条件を考慮すると従来の方式のみでは万全と
いうことができないという問題点がある。Considering these worst-case conditions, there is a problem in that the conventional method alone cannot be completely reliable.

作の流れを第５図に示す。The room temperature slope detection unit 25 detects the room temperature T measured by the room temperature measurement unit 23.
The degree of change ΔT' per unit time is detected and stored in the room temperature slope storage section 26. The flame current slope detection section 27 detects the degree of change Δf in the flame current If measured by the flame current measurement section 28 per unit time. The exhaust gas concentration calculation unit 29 receives ΔT from the room temperature slope storage unit 26 and ΔT from the flame current slope detection unit 27.
If, from the timer section 24, the combustion amount Q is inputted from the combustion amount storage section 30 which stores the combustion amount during the elapsed time t1 from the start of combustion, and the indoor CO concentration 1cOft is calculated. An example of the calculation will be explained next. Assuming that the indoor area is f and the number of ventilations in R1 is N, the characteristics of time and room temperature have a larger slope as NXR becomes smaller, as shown in FIG. Therefore, the input ΔT and NXR from the room temperature gradient storage section 26 have the characteristics shown in FIG. Third
The characteristics in the figure change as the combustion amount Q changes, and N
XR is calculated using the function N X R = f 1 (ΔT, Q) of the input ΔT from the room temperature gradient storage unit 26 and the input Q from the combustion amount storage unit aO. As shown in Figure 4, the flame current 1 (and the oxygen concentration 02) have the characteristic that the current decreases almost linearly as the concentration decreases (it may increase depending on the design of the burner), so the oxygen concentration 02 It can be defined as -order number 02 = blXI, +b2 (bl, b2 are constants) of current 1. Therefore, the input ΔI from the flame current slope detection unit 27 (from which the degree of change in oxygen a change per unit time is defined as Δ02 = b1 It is calculated using the formula ×Δxl.It is known that the indoor oxygen concentration 02 can generally be approximated by a function of NXR, so the function can be given, and the inverse function of the NXR calculated earlier can be given.
and Δ02, the input Q from the combustion amount storage section 29, and the time t from the start of combustion input from the timer section 24, the number of ventilations N is calculated.
It is known that can be approximated by the function N=f2 (NXR, Q, t, Δ○2). k is a burner-specific constant. From the previously calculated NXR and N, the input Q from the combustion amount storage section 29, and the input t from the timer section 24, CO is calculated from the function C0=f3 (NxR, N, Q, t>.Exhaust gas concentration calculation section 29 The CO concentration in the room is calculated from the following calculations, and when the calculation result exceeds a predetermined value a (for example, 10,100 pp), the safety shutoff section 31 closes the safety valve 1.
0 to stop combustion in the burner 13. Further, when a value a slightly smaller than a (for example, 90 ppm)'z is exceeded, the notification section 32 issues two alarms to urge the user to ventilate. Figure 5 shows the flow of operations to the north.
以上、実施例ではガスファンヒータについて説明したが
、別の燃料、例えば石油ファンヒータにも全く同様の効
果を得るものであり、この場合は、安全弁１０の代わシ
に給油ポンプ等を動作してもよい。又、近似式は精度を
得るためにもっと複雑 。In the above embodiments, a gas fan heater has been described, but the same effect can be obtained with another fuel such as an oil fan heater. In this case, a fuel pump or the like is operated in place of the safety valve 10. Good too. Also, the approximation formula is more complicated to obtain accuracy.
な近似式、あるいは逆にもっと簡略化した近似式を用い
て同様の効果を得ることもできる。又、同様の近似式で
人体に有害なガスＮ○２の濃度を演算することもできる
。A similar effect can also be obtained using a simple approximation formula or, conversely, a more simplified approximation formula. Furthermore, the concentration of the gas N○2, which is harmful to the human body, can also be calculated using a similar approximate formula.
