When the dot / fire buttons 14 and 36 are pressed farther from the position shown in FIG. 3, the micro switches 611 and 612 for supplying battery power to the control unit 6 are turned on.

Note that the point / fire button 14, 24, 36 is pushed all the way down (the position in FIG. 3) and stops when the hand is released. Then, in the case of extinguishing the fire, push it in again and release your hand to return to the fire extinguishing position (position). Such an operation is performed by a conventionally known heart cam mechanism.

The dry battery 7 is formed by connecting two single type manganese batteries in series, and stores electric power for operating the LED 4, the buzzer 5, and the control unit 6.

Next, advantages of the gas table A of this embodiment will be described below. [A] The control unit 6 controls the H burner 11 when there is a risk of scorching, when the oil is overheated, when it is overheated to 290 ° C. or more, or when an error occurs during continuous use for more than 2 hours (see FIG. 7). The fire is extinguished and an error is notified by both the sounding of the buzzer 5 and the emission display of the error code until the micro switches 611 and 612 are turned off.
During the ringing of, the light emission display of the error code on the LED 4 is stopped, so that the current consumption is suppressed from about 110 mA to about 70 mA / 40 mA, and the battery voltage is not sharply reduced. Can be extended. In addition, since the occurrence of an error due to the carelessness of the user occurs relatively frequently, the effect of suppressing the current consumption is great.

[A] In the case of a circuit failure such as a thermistor disconnection, a thermistor circuit failure, or an SV circuit failure, the control unit 6 extinguishes the H burner 11 and the grill burners 31, 32 and, as shown in FIG.・ Fire button 14, 3
Until 6 is returned to the fire extinguishing position (the position in FIG. 3), the buzzer 5 is continuously sounded to notify the failure, but the error code is displayed after the buzzer 5 has stopped sounding. As a result, a large current consumption does not flow during the continuous sounding of the buzzer 5, and the running out of the battery during the continuous sounding can be prevented as much as possible.

[C] At the time of the remaining 30 seconds of the grill timer, the buzzer 5 sounds and the LED 4 is displayed, so that the user is not confused. Note that the actual working time of the buzzer 5 at this time is short (90 ms sounding-40 ms stop × 3 = 3
Therefore, since the voltage is restored before the battery voltage monitoring circuit operates, the replacement time of the dry battery 7 is not advanced.
