本考案はサーモカップルを用いた燃焼安全装置に関する
ものである。[Detailed Description of the Invention] The present invention relates to a combustion safety device using a thermocouple.
・従来この種安全装は第１図に示す構成となっていた。- Conventionally, this type of safety equipment had the configuration shown in Figure 1.
すなわち、１は電源、２はリレースイッチで、そのリレ
ーコイル３には点火スイッチ４が直列に接続しである。That is, 1 is a power supply, 2 is a relay switch, and an ignition switch 4 is connected in series to the relay coil 3.
また５はサーモカップル６の熱起電力によって附勢され

チ８に直列接続した始動用リレーコイル９と安全スイッ
チ１０とから構成した安全リレースイッチにして、上記
安全スイッチ１０には電磁弁１１が接続しである。Further, 5 is a safety relay switch composed of a safety relay coil 7 energized by the thermoelectromotive force of the thermocouple 6, a starting relay coil 9 connected in series to the switch 8 of the relay switch 2, and a safety switch 10. A solenoid valve 11 is connected to the safety switch 10.
今、点火スイッチ４を閉じるとリレースイッチ２のリレ
ーコイル３が附勢されてスイッチ８を閉じ、また安全リ
レースイッチ５の始動用リレーコイル９が附勢されて安
全スイッチ１０を閉じる。Now, when the ignition switch 4 is closed, the relay coil 3 of the relay switch 2 is energized to close the switch 8, and the starting relay coil 9 of the safety relay switch 5 is energized to close the safety switch 10.
しかるに電磁弁１１が開いて燃焼が開始される。However, the solenoid valve 11 opens and combustion begins.
そしてこの燃焼によってサーモカップル６が熱起電力を
生じ安全リレーコイル７を附勢すれば、後はこの安全リ
レーコイル７で安全スイッチ１０の閉成が保持されるも
のであり、したがってここで点火スイッチ４を開き、リ
レースイッチ２を開成することができる。When the thermocouple 6 generates a thermoelectromotive force due to this combustion and energizes the safety relay coil 7, the safety switch 10 is kept closed by the safety relay coil 7. Therefore, the ignition switch is activated at this point. 4 can be opened to open the relay switch 2.
もし何かの要因で燃焼立消えを起した場合はサーモカッ
プル６の熱起電力がなくなって安全スイッチ１０が開く
。If combustion goes out for some reason, the thermal electromotive force of the thermocouple 6 disappears and the safety switch 10 opens.
ところで上記従来の装置ではサーモカップル６の熱起電
力の立上がり特性によって点火動作時間が左右され、第
２図に示すように安全スイッチ１０を閉し得る安全リレ
ーコイル７の附勢力Ａまで時間りかかり不便であった。By the way, in the conventional device described above, the ignition operation time is affected by the rise characteristics of the thermoelectromotive force of the thermocouple 6, and as shown in FIG. It was inconvenient.
またサーモカップル６と安全リレーコイル７を結ぶリー
ド線が長くなったりして抵抗が大となると安全リレーコ
イル７の附勢力Ａまで熱起電力が達せず、安全動作が不
確実となるものであった。Furthermore, if the lead wire connecting the thermocouple 6 and the safety relay coil 7 becomes long and the resistance increases, the thermal electromotive force will not reach the auxiliary force A of the safety relay coil 7, making safe operation uncertain. Ta.
本考案は上記従来の欠点を除去したもので、すなち第３
図に示すごとくスイッチ８と並列に抵抗１２を接続し、
上記スイッチ８が開放していても抵抗１２を介して始動
用リレーコイル９に電流を流すようにしたものである。The present invention eliminates the above-mentioned conventional drawbacks, that is, the third
As shown in the figure, connect the resistor 12 in parallel with the switch 8,
Even if the switch 8 is open, current is caused to flow through the starting relay coil 9 via the resistor 12.
なお第３図において第１図と同一部分には同一符号を附
し、説明は省略する。Note that in FIG. 3, the same parts as in FIG. 1 are given the same reference numerals, and explanations thereof will be omitted.
上記抵抗１２の大きさはこれを介して流れる電流による
安全リレーコイル７の附勢力が第４図のＡよも低いＡ′
になるように設定されている。The size of the resistor 12 is A', which is lower than A in FIG.
is set to be.
上記第３図の構成によれば上記安全リレーコイル７の附
勢力Ａ′があるため点火後１２時間で点火スイッチ４を
開くことができ、第２図のｔｌより大巾に短縮できるも
のである。According to the configuration shown in FIG. 3, the ignition switch 4 can be opened 12 hours after ignition because of the auxiliary force A' of the safety relay coil 7, and the time can be greatly shortened compared to tl in FIG. 2. .
また安全リレーコイル７の抵抗１２を介しての電流によ
る附勢力Ａ′では安全スイッチ１０を閉成保持できない
ので、燃焼立消えによりサーモカップル６が熱起電力を
生じなくなったら上記安全スイッチ１０が開いて電磁弁
１１が閉成される。Further, the safety switch 10 cannot be kept closed by the force A' generated by the current through the resistor 12 of the safety relay coil 7, so when the thermocouple 6 stops generating thermoelectromotive force due to combustion extinction, the safety switch 10 opens. Solenoid valve 11 is closed.
このように本考案は、燃焼立消え時の安全性はもちろん
、点火動作時間の短縮化が図れ、またサーモカップルの
出力を小さくしても確実な安全動作が得られるものであ
り、さらにサーモカップルのリード線が長くできるので
装置の設置がしやすくなるものである。In this way, the present invention not only provides safety when combustion goes out, but also shortens the ignition operation time, and provides reliable safe operation even when the output of the thermocouple is reduced. The lead wire can be made longer, making it easier to install the device.
さらに本考案によれば出力の大きな電磁安全弁あるいは
安全リレースイッチを使えるという使用上の効果を奏す
る。Furthermore, the present invention has the advantage of being able to use a high-output electromagnetic safety valve or safety relay switch.
