01 is energized for a predetermined time to maintain the valve open, the temperature control solenoid valve 103 is opened, the ignition electrode 14 is energized, the left stove 1 is ignited, and combustion is started by a large fire. Elapsed time t ₁
At this point, when the detected temperature reaches the set temperature of 190 ° C., the control unit 4 sounds the notification buzzer 5 and stops energizing the temperature control solenoid valve 103 (the temperature control solenoid valve 103 is closed). The firepower of the M burner 13 is switched to small fire. After that, the control unit 4 detects the detected temperature = 190.
The combustion of the M burner 13 is controlled by opening and closing the temperature control solenoid valve 103 so that the temperature becomes ± 4 ° C. (detection temperature = 190 ° C. at the first time). That is, at the elapsed time t ₂ , the detected temperature is 186 ° C. (190 ° C.-4
(° C), the control unit 4 determines that the temperature control solenoid valve 103
When the detected temperature reaches 194 ° C. (190 ° C. + 4 ° C.) at the elapsed time t ₃ , the power supply to the control unit 4 is restarted (the temperature control solenoid valve 103 is opened) to increase the heating power of the M burner 13 to a large fire. Stops the energization of the temperature control solenoid valve 103 (the temperature control solenoid valve 103 is closed) and switches the heat power of the M burner 13 to small fire. In addition, when repeating the above large fire-small fire,
When the detected temperature reaches the set temperature of 190 ° C., the notification buzzer 5 is not sounded, so there is no problem that the buzzer sounds frequently and the user is confused. Here, steps s1 and s2 in FIG. 4 are the elapsed time t ₁ to the elapsed time t during which the temperature is controlled and burned at the set temperature of 190 ° C. ± 4 ° C.

This shows the case where the temperature is changed to ° C.

The advantages of the gas table A of this embodiment will be described below. (A) The buzzer 5 sounds when the detected temperature reaches the set temperature (for example, 190 ° C.), and the set temperature is changed (for example, 1
(90 ° C. → 140 ° C.), the notification buzzer 5 sounds again after the detected temperature reaches the set temperature. Therefore, when the user hears the sound of the notification buzzer 5, he / she can confirm that the detected temperature has reached the changed set temperature and can restart the interrupted cooking. It is also easy to use. (Yes) The set temperature is confirmed when one second has elapsed since the pressing of the "-" key 31 and the "+" key 32 was released. For this reason, it is possible to prevent the problem that the notification buzzer 5 sounds during the operation of the key, or the heating power of the M burner 13 is switched every time the "-""+" keys 31 and 32 are operated. (U) Normally, the notification buzzer 5 sounds when the detected temperature reaches the set temperature (first time), but as shown in FIG.
When the detected temperature reaches the set temperature (elapsed time 833) within 5 seconds after the start of combustion (elapsed time 831), the point when the forced large fire period of 5 seconds (necessary for ensuring ignition performance) ends (elapsed time) At time 834), the notification buzzer 5 is sounded while the fire is turned down. (E) Normally, the set temperature is fixed when one second elapses after the pressing of the "-" key 31 and the "+" key 32 is released, but as shown in FIG. If the "key 32) is continuously pressed, the set temperature is confirmed (for example, 220 ° C) after one second has elapsed (elapsed time 852) from the time when the display of the set temperature reaches the upper limit of 220 ° C (elapsed time 851). Then, the notification buzzer 5 sounds when the detected temperature reaches the set temperature (elapsed time 853) even while the key is being pressed,
Even if such a special key operation is performed, the notification function of the notification buzzer 5 is not hindered.
