（産業上の利用分野）
本考案は、主として燃焼器具用の点火回路装置
に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to an ignition circuit device for a combustion appliance.
（従来の技術）
従来、この種の点火回路装置は、点火トランス
と直列に接続されたコンデンサを電源により充電
し、スイツチング素子を所定時間間隔で閉成して
該コンデンサの電荷を間歇的に放電し、この放電

電圧で電極間にスパークを発生させるように構成
するのが一般である（例えば実開昭55−64674号
公報参照。）。(Prior Art) Conventionally, this type of ignition circuit device charges a capacitor connected in series with an ignition transformer using a power source, and closes a switching element at predetermined time intervals to intermittently discharge the charge in the capacitor. However, it is common to use a voltage induced in the secondary coil of the ignition transformer by this discharge current to generate a spark between the electrodes (see, for example, Japanese Utility Model Application No. 55-64674).
（考案が解決しようとする問題点）
しかし、この回路装置は、回路を電源から切り
離さないかぎり永続的にスパークが断続して発生
するから、バーナの点火を確認した後回路を開成

電源に接続する必要があつて取扱いが不便である
不都合がある。(Problem that the invention seeks to solve) However, with this circuit device, sparks are generated intermittently unless the circuit is disconnected from the power supply, so it is necessary to open the circuit after confirming that the burner has ignited. Furthermore, when a misfire occurs after ignition, it is necessary to reconnect to the power source, which is inconvenient to handle.
また、この回路はスパークの発生間隔が室温に
関係なく一定であるから、室温が比較的高温時に
スパーク間隔を適当な時間に設定すると比較的低
温時にバーナになかなか点火しない不都合を生ず
る。 Further, in this circuit, the spark interval is constant regardless of the room temperature, so if the spark interval is set to an appropriate time when the room temperature is relatively high, the burner will not easily ignite when the room temperature is relatively low.
本考案は、従来のかかる不都合が無い点火回路
装置を得ることをその目的とするものである。 It is an object of the present invention to provide an ignition circuit device that does not have such disadvantages as the conventional one.

パークの回数は少なくなる。 When the power supply elements 1 1 , 1 2 are connected to the power supply, a DC voltage is applied to the DC voltage application terminals 11 1 , 11 2 ,
The first capacitor 5 is charged via the diode 2, and the second capacitor 6 is similarly charged at a predetermined time. When the voltage of the second capacitor 6 reaches a predetermined value, the element 10 such as a neon tube becomes conductive and the switching element 8 becomes conductive. This conduction forms a discharge circuit for the first capacitor 5, causing the capacitor 5 to discharge, and a voltage induced in the secondary coil 42 of the ignition transformer 4 by the discharge current causes a spark between the electrodes. Until the pilot burner is ignited by this spark, sparks are generated a predetermined number of times determined by the resistance value of the thermistor 9 and the resistance value of the resistor 7 according to the room temperature, and the capacitance value of the second capacitor 6. When the room temperature rises relatively, the resistance value of the thermistor 9 decreases, and accordingly, the charging time of the capacitor 6 becomes slower and the number of sparks per certain period of time decreases.

The resistance value further decreases significantly, and the charging voltage of the capacitor 6 is no longer sufficient to cause the element 8 to conduct. Thus, spark generation stops.

In addition, the spark generation automatically stops after ignition, making it easy to handle.
