を行っていた。Conventional technology Conventional gas stoves of this type turn burner combustion on and off by opening and closing an on-off valve installed in the gas passage to maintain a preset set temperature, and to detect deviations between the set temperature and the actually detected temperature. Depending on the situation, the temperature can be adjusted by reducing the thermal power of the main burner using a proportional solenoid valve that controls the power supply and adjusts the amount of gas, or a control valve that uses liquid expansion to adjust the amount of gas by changing the gas passage area. In addition, they used manual knobs to control the amount of gas and reduce the heat to reheat or keep food warm.

burns and heats food 2 from cooking pot a. Note that if a desired cooking mode is previously set using the cooking knob 10 of the mode setting section 9 by closing the microswitch 27, this signal is input to the control section 16 and output to the safety valve 17 and the solenoid valves 21, 22, and 23. . Do n. The thermocouple 15 is
It is heated by the pilot burner 5b and generates a thermoelectromotive force, which sends a signal to the safety valve 17 via the control unit 6, and the safety valve 17 changes from a mechanically opened state with the cock knob 7 to an electrically opened state. Therefore, if the pilot burner 5b misfires, the control section heavy 6 is activated and the safety valve type 7 is closed to maintain safety. When used in this way, the temperature sensor 6 controls the cooking mode set by the cooking knob 10.
The temperature of the food 2 to be cooked is inputted to the control unit 16 from the safety valve type 7.
and outputs to solenoid valves 2 and 22, 23 to control the firepower according to the cooking mode. A buzzer 8 attached to the control unit 16 is used to notify the user at an appropriate operating point of the cooking mode. For example, in the rice cooking mode shown in Figure 7, when the temperature reaches T2, and in the boiling mode, the temperature reaches T1.
Then, when the temperature reaches T2, or when the temperature reaches Tl in the temperature control mode, etc.

The pilot burner 5b quickly ignites the flame, causing no odor caused by unburned gas, and the burner 5 is connected to the main burner 6.
Since the pilot burner 5b and the pilot burner 5b are separated and integrally formed, even if boiling over occurs in the cooking pot 3, the main burner 6a is extinguished and the pilot burner sb is burned (the heat generated by the thermocouple 16 is removed). It is also excellent in safety, as the risk of raw gas being generated from the main burner 6a (which has electric power) is impossible because it is configured so that the flame can always be transferred from the pilot burner 5b. Note that if the pilot burner 5b is also extinguished due to boiling over, the thermoelectromotive force of the thermocouple 15 disappears, and the control section 16 closes the on-off valve 17.
