場合があり、使い勝手が悪いという欠点があった。Problems to be Solved by the Invention The temperature detection device section of a conventional electric stove has the above-mentioned structure, but the upper surface of the sheathed heater 21 and the heat shield tube 28
There are many cases where the top surface is at the same height due to errors during assembly in processing 1, and there is a step, and the bottom shape of the heating container 26 such as a pot placed on the sheathed heater 21 also varies. However, a gap is created between the upper end of the heat shield cylinder 28 and the bottom of the heating container 26, and the stability of the state of heat transfer to the temperature sensing element unit 24 due to radiant heat and convection heat from the sheathed heater 21 becomes low. This has the drawback that malfunctions in the temperature control of the food inside the container 26 become serious, and it may not be possible to cook the food as desired, making it inconvenient to use.

ことができる。Effect With the above-described configuration, when the heating container is placed on the heating element, the upper end of the heat shield ring comes into contact with the heating container due to spring pressure, and the temperature sensing element unit also comes into contact with the heating container due to spring pressure. Therefore, even if the bottom surface of a heating container such as a pot is slightly uneven, the heat shielding ring and temperature sensing element unit will come into contact with the bottom surface of the heating container, and the heat shielding state by the heat shielding ring will be stable. Since the temperature of the heating element unit changes in accordance with the temperature change within the heating container, temperature detection performance is improved and an easy-to-use electric stove can be provided.
