複雑な機構や器具を取り付けないことが望ましい。2. Description of the Related Art A large-sized rice cooker that cooks a large amount of rice at a time like a commercial rice cooker inserts and removes a large-capacity pot continuously and repeatedly from the rice cooker body. This increases the weight of the pot,
It is necessary to improve the impact resistance of each part. (JP-A-6-13
No. 3860) For such a reason, electric parts are attached to the pan,
It is desirable not to install complicated mechanisms and instruments.

を捕まえて炊飯の完了を知るようにしている。However, as a method of detecting the progress or completion of rice cooking without attaching an electric component (such as a temperature sensor) to a lid or a pan, a method similar to a general household rice cooker is used. A temperature sensor provided on the rice cooker body side is applied to the bottom of the pan to detect the temperature of the pan, and indirectly catch the temperature of rice and water so as to know the completion of rice cooking.

がらない欠点があった。In this detection method, since the shape of the pot is large, the temperature difference between the respective parts is considerably large, and even if the temperature of the bottom of the pot corresponding to the temperature sensor rises, the other parts, especially the corners of the rectangular pan, may be used. There was a drawback that the heat was extremely low and it was hardly cooked.

態になっていなかったり、炊飯完了状態になっていない
場合があった。[0005] In addition, since the shape of the pot is large as described above, the temperature change of each part of the pot becomes large due to the change of the outside air temperature. Even when the temperature was detected, there were cases where the inside of the pot was not actually in a boiling state or cooked in a completed state.
【0006】本発明は、鍋の形状が大きく、且つ外気温
が変化した場合であっても確実に炊飯状態(沸騰や炊飯
