である。FIG. 2 is a specific embodiment of the ignition confirmation device of the present invention. In the figure, A is a control circuit block corresponding to the thermoelectromotive force detection unit 1 and the reference value setting unit 2 in FIG. 1, B is a comparator corresponding to the voltage comparison unit 3, and C is a time detection unit 4 and the reference value setting unit. Reference numeral 5 denotes a control circuit block corresponding to the time comparison unit 6, and reference numeral D denotes a display lamp using an LED corresponding to the display unit 7.
第２図を用い動作を説明する。 The operation will be described with reference to FIG.
先ず、熱電対Ｔに熱起電力がない場合、抵抗8,9,10に
よりコンパレータ34の出力はＨレべルとなっている。し
かし、熱起電力がある一定以上発生するとコンパレータ
34の入力電圧が低下し、出力はＬレベルに反転する。
それにより、トランジスタ27,31,30が動作しLED32が点
灯する。又、LED32が点灯すると同時に、トランジスタ2
6,29が動作するためコンデンサ35からの電荷の放出が始
まり、その電圧が抵抗19,20で設定されている電圧以下
になる（一定時間ｔ秒後）とコンパレータ33の出力がＨ
レベルになり、LED32は消灯する。First, when there is no thermoelectromotive force in the thermocouple T, the output of the comparator 34 is at the H level by the resistors 8, 9, and 10. However, when the thermo-electromotive force is over a certain level, the comparator
The input voltage at 34 drops, and the output is inverted to L level.
As a result, the transistors 27, 31, and 30 operate to turn on the LED 32. Also, at the same time when the LED 32 lights up, the transistor 2
Since the capacitors 6 and 29 operate, the discharge of the electric charge from the capacitor 35 starts. When the voltage becomes equal to or lower than the voltage set by the resistors 19 and 20 (after a certain time t seconds), the output of the comparator 33 becomes H
Level, and the LED 32 goes out.

ものでも寿命が差ほど気にならない。Effect of the Invention As described above, according to the present invention, if the ignition lamp is provided, the ignition part where the combustion part such as the grill cannot be directly observed can be visually observed, though indirectly, while standing the ignition part where it cannot be directly observed. In addition, the lighting time of the display lamp is determined to be a certain fixed time, so that even a small-capacity battery such as a battery does not care much about the life.
