摘要： PURPOSE:To permit the visual confirmation of ignition by an operator indirectly while standing up, by a method wherein the ignition is informed of by indication when the thermal electromotive force of a thermocouple provided in a combustion unit has become a given value or higher, thereafter, the indication is extinguished when a given time has elapsed. CONSTITUTION:When there is no thermal electromotive force in a thermocouple T, the output of a comparator 34 shows H-level by resistors 8, 9, 10. However, when the thermal electromotive force of a given value or higher is generated, the plus input voltage of the comparator 34 is reduced and the output of the same is converted into L-level. Accordingly, transistors 27, 31, 30 are operated and a LED 32 is lighted. The transistors 26, 29 are operated simultaneously with the lighting of the LED 32, therefore, the discharge of a charge from a capacitor 35 is started. When the voltage of the capacitor 35 has become lower than a voltage, set by the resistors 10, 20, (after a given time (t)), the output of the comparator 33 shows H-level and the LED 32 is put OFF.

摘要： PURPOSE:To prevent a fault such as a fire hazzard or the like by stopping the supply of a fuel by a microcomputer when an ignition key is short-circuited for a predetermined period of time, and further making it impossible to use the apparatus in its entirety when the ignition key continues to be short-circuited in the burning apparatus such as a gas range for home use. CONSTITUTION:When it is assumed that an ignition key 9a included in a key matrix 9 is in a short-circuited state, a central processor 15 judges that the ignition key 9a judged by a key reading judging part 14 is continuously inputted, and sends a signal to a timer 11 thereby to start counting. When the central processor 15 judges that the time where the ignition key 9a is in a short- circuited state is a predetermined time T1 in comparison in a comparison part 11a, a signal is sent to switching means 2 through a motor position monitoring part 17 and motor control circuit means 3, whereby only a burner 1 is automatically fire-extinguished. Further, when the ignition key 9a continues its short- circuited state for a time longer than a predetermined time T1, and the central processor 15 judges that the count of the timer 11 is a predetermined time T2 in comparison in a comparison part 11a, a solenoid valve 4 is closed and the entire part of the apparatus is rendered inoperable.

摘要： PURPOSE:To improve the safety of the controller by providing a safety circuit so that the combustion is stopped when an automatic return type fuel control valve operating switch is short-circuited, in the controller of the gas heater and the like. CONSTITUTION:When a fire-extinguishing button 9 is depressed and hand is off, a microcomputer 20 discharges an igniter (not shown), opens a motor cock 15 and a solenoid valve 14, and feeds a gas to a burner to ignite the gas. After the passage of a predetermined time, for example, five second after depressing the fire-extinguishing button 9, the microcomputer 20 again reads the signal from the fire-extinguishing button 9. At this time, if the fire-extinguishing button 9 is continued to be depressed, the safety circuit 21 of the microcomputer 20 acts to put the motor cock 15 at a closed position, and further the solenoid valve 14 is opened to stop the combustion. By this construction, unexpected combustion due to the turning ON of an inadvertent switching operation can be prevented and the safety of the controller is realized.
