制御手段２２とを備えている。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 2, reference numeral 11 is a pot for cooking rice, and the pot 11 is detachably mounted on a bottom heater 13 installed in an internal part of the protective frame 12. A side heater 14 for rice cooking and a side heater 15 for heat retention are arranged on the outer surface of the upper portion of the protective frame 12. Reference numeral 16 denotes a lid heater, and the lid heater 16, the bottom heater 13, the rice cooking side heater 14, and the heat retaining side heater 15 correspond to the heating means 21 in FIG. In FIG. 2, 17
Is a bottom temperature detecting means for detecting the temperature of the rice in the pot 11, and the signal from the bottom temperature detecting means 17 determines the temperature during the normal rice cooking operation. Reference numeral 18 is a temperature detecting means which faces the outer surface of the upper portion of the pot 1 and which is attached to the protective frame 12. Reference numeral 19 denotes a control unit, and as shown in FIG. 1, the control unit 19 receives a signal from the temperature detecting means 18 and judges the temperature has reached a predetermined temperature. And a heating control means 22 for stopping the output to the heating means 21 in response to a signal from the temperature determination means 20.

る。Next, the operation of the above configuration will be described. Until the water is boiled inside the pot 11 and it is wiped up, the upper part of the pot 11 is an air layer, so the temperature detecting means 18 in contact with the outer surface of the upper part of the pot 11 reaches a predetermined temperature. do not do. Then, when water boils inside the pot 11 to cause boiling, the upper part of the pot 11 becomes a layer of water boiled by the boiling, so that the temperature near the temperature detecting means 18 in contact with the outer surface of the upper part of the pot 11 Rises to a predetermined temperature. Then, the temperature determination means 20 detects this temperature change as the temperature detection means 1.
The temperature control means 22 receives a signal from the temperature determination means 20 and stops the output to the heating means 21 when the temperature is determined as a signal from the temperature determination means 8 and reaches a predetermined temperature.
