Title: Combustion controller
Inventor: MIYANAKA MOTOSHI
IPC: F23N5/26
Filed: 1982-03-10
Abstract: PURPOSE:To prevent the automatic reset of a combustion controller at the time of recovering an electric power source after the power source is interrupted by providing a magnetically holding type keep relay, energizing the coil of the keep relay at the OFF time of an operation switch and allowing the relay to be reset by the switch. CONSTITUTION:A transistor (Tr)14 is interrupted OFF at the normal time. When a combustion control circuit 8 detects the malfunction of a combustion device in this state, a warning circuit 9 will operate to energize the coil 10 of a keep relay, thereby opening a contact 6, and the circuit 8 becomes stopping state. Even if a power source 1 is interrupted at this time, the contact 6 is maintained at its open position. In order to reset the contact from this state, an operation switch 2 is opened, and is then closed. That is, when the switch 2 is shifted to an operation side terminal 3 to close the contact, the Tr14 is interrupted, and the coil 10 is not energized. However, when the switch 2 is shifted to the stop side 4, a base current will flow through the Tr14, thereby conducting the Tr, and a reverse current will flow through the coil 10, thereby causing the keep relay to be reset.
