消耗し、寿命が短かいと云う欠点があった。However, burners that require continuous generation of sparks even after ignition have the disadvantage that the sparks wear out the electrodes of the spark plug, resulting in a short lifespan.

低減するようにしたことを特徴とする。Even in burners that require continuous generation of sparks even after ignition, the present invention requires the greatest amount of spark energy and number of sparks only during initial ignition.
Focusing on the fact that once the temperature of the combustion chamber has risen, the spark does not have to be the same as the initial one, we have provided a means to detect ignition and a means to reduce the spark energy and number of sparks using this detection means. It is characterized by automatically reducing the spark energy and the number of sparks.

する。By detecting the temperature caused by this combustion as, for example, the wall temperature of the combustion chamber by the temperature detecting element 8, the contact force probe of the temperature detecting element 8 is opened, and current flows through the short-circuited resistor I. As a result, the resistance value of this part increases.

トランジスタ１Ｄのベース電流は小さくなり、トランジ
スタ１０は閉から開となる。Due to this light detection, the resistance of the light detection circuit 11 increases,
The base current of transistor 1D becomes small, and transistor 10 changes from closed to open.
従って短絡されていた抵抗Ｉを通り電流が流れるように
なる。Therefore, current begins to flow through the short-circuited resistor I.
そこで火花エネルギ、火花回数が低減することになる。Therefore, the spark energy and the number of sparks are reduced.
