【０００２】[0002]
従来、石油ファンヒーター等の炎の検知は、炎の上下間いわゆるバーナーと炎 の内部との２点間の電気抵抗値で炎の有無検知を行っていました。 しかし、センサー部や、バーナー部表面に酸化シリコン等の絶縁物が燃焼によっ て付着した場合には、２点間の電気抵抗値が増大し感度が低下し正常な燃焼中に もかかわらず炎を無し、と判定し、燃焼をストップさせるような誤動作をおこし たりして不適当であった。 Conventionally, the detection of flames in oil fan heaters, etc. has been performed by detecting the presence / absence of flames by the electrical resistance between the upper and lower sides of the flame, the so-called burner, and the inside of the flame. However, if an insulator such as silicon oxide adheres to the surface of the sensor or burner due to combustion, the electrical resistance between the two points will increase and the sensitivity will decrease, resulting in a flame even during normal combustion. It was not appropriate because it was judged to be no, and a malfunction such as stopping the combustion occurred.

本案は、その欠点を除いて、炎の有無検知を確実に行い周囲の環境に左右され ることもなく正確に判定できるようにしたシステムを開発しようとするものであ る。 This proposal aims to develop a system that can detect the presence or absence of flames reliably and make accurate judgments without being affected by the surrounding environment.

いまその解決手段を図面に追いながら説明すれば、 （イ）バーナー（２）上部に炎検知センサー（１）を一定距離をおいて固定す る （ロ）炎検知センサー（１）である発電素子は、炎（４）の熱により起電力が 生じる。炎検知センサー（１）から発生した起電力は、判定回路（３）に送られ 判定回路（３）は、起電力値で炎の有無を判定する。 The solution means will be described with reference to the drawings. (A) The flame detection sensor (1) is fixed to the upper part of the burner (2) at a certain distance. (B) The power generation element that is the flame detection sensor (1). Generates electromotive force due to the heat of the flame (4). The electromotive force generated from the flame detection sensor (1) is sent to the determination circuit (3), and the determination circuit (3) determines the presence or absence of flame based on the electromotive force value.

本案は、以上のような構造であるからこれを使用するときは、燃焼と同時にバ ーナー（２）上部に炎（４）が現れ熱により発電素子である炎検知センサー（１ ）に起電力が生じ、この起電力は、判定回路（３）に入力され炎（４）を有りと 判定する。又、燃焼していないときは、もちろん炎（４）も無い状態なのでバー ナー（２）上部にある発電素子である炎検知センサー（１）には、起電力は生じ ず、したがって判定回路（３）には何も入力はなく炎を無しと判定する。 Since this plan has the structure as described above, when using it, a flame (4) appears at the top of the burner (2) at the same time as the combustion, and an electromotive force is generated in the flame detection sensor (1) which is a power generation element due to heat. This electromotive force is input to the determination circuit (3) and the flame (4) is determined to be present. When the combustion is not in progress, of course, there is no flame (4), so no electromotive force is generated in the flame detection sensor (1), which is the power generation element above the burner (2), and therefore the judgment circuit (3) There is no input to) and it is judged that there is no flame.
【０００６】[0006]
したがって、燃焼に際し炎の有無を周囲の環境に関係なく確実に正確に判定で き機器の動作を安定に保ち誤動作をなくすことが出来る。 Therefore, it is possible to reliably and accurately determine the presence or absence of a flame during combustion regardless of the surrounding environment, and to keep the operation of the equipment stable and prevent malfunctions.
