One burner may be provided with one. 22 and 23 are transformers for applying high voltage to the spark plugs; in this embodiment, two spark plugs are connected to one transformer, and the spark plugs are respectively arranged in different gas burners. Further, the transformers 22 and 23 are simultaneously energized by the operation of an ignition circuit, which will be described later. Next, the electric circuit will be described. It has an ignition circuit 27 consisting of a relay 25 that opens and closes a switch 24 that controls energization to the transformers 22 and 23, and a driving transistor 26 for the relay 25. The input circuit, that is, the input circuit of the transistor 26 is connected to a parallel circuit of combustion command circuits 30 and 31, which are outputted by turning on, for example, an operation switch (not shown) via diodes 28 and 29, and at least one of the command circuits is connected to the input circuit of the transistor 26. The output from the transistor 26 turns on, and the relay 25 is activated to energize the transformers 22 and 23. Further, the command circuits 30, 31 are connected to flame detection circuits 34, 35 via diodes 32, 33, and each flame detection circuit 34, 35 is connected to the flame detection paths 16, 17, which are connected to the gas burners 13, 1.
When the combustion flame No. 4 is detected, the circuit is activated and the circuit including the diodes 32 and 33 is grounded.

するのである。 The present invention has the above-described configuration, and when one combustion is performed, for example, combustion in the heater 11, the command output from the combustion command circuit 30 is transmitted to the input circuit of the transistor 26 of the ignition circuit 27 by turning on the operation switch (not shown). The transistor 26 is turned on, the relay 25 is activated, the switch 24 is closed, the transformers 22 and 23 are connected, and the gas ejected from the gas burner 13 is discharged and ignited, and the heater 11 is heated. It will be done. and gas burner 13
ignites and the flame detector 16 detects the combustion flame,
Since the flame detection circuit 34 is activated and the circuit via the diode 32 is grounded, the command output is cut off, the transistor 26 is cut off, and the relay 25 stops operating, stopping the discharge from the transformers 22 and 23. be.

7 is activated, and the ignition circuit 27 is deactivated because both gas burners 13 and 14 are ignited together, and both flame detection circuits 3 and 3 are activated.
4 and 35 are activated together.

火制御装置を提供できるのである。 Therefore, according to the present invention, the ignition circuit 27 can be used both for discharging to the gas burners 13 and 14 that heat the heaters 11 and 12, and for controlling the discontinuation of the discharging.
The circuit configuration of this type of composite combustion appliance can be extremely simplified, and an ignition control device that is less likely to malfunction and easier to maintain and inspect can be provided.

危険性はなくなり、この種器具の点火時の安全性
に大きく寄与できる利点がある。 In the present invention, when the ignition circuit 27 is activated, discharge occurs even when one of the gas burners does not perform combustion. If one transformer were to fail, sparks would still be generated in both burners, so even if one transformer were to fail, ignition would not occur and there would be a risk of raw gas being released and causing an explosion. This has the advantage of greatly contributing to safety when igniting this type of appliance.
