本発明は、調理容器の外底面と接触して温度検
知を行う温度センサに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temperature sensor that detects temperature by contacting the outer bottom surface of a cooking container.

熱電対の断線、はずれが生じ、温度センサの役目
をなさないものとなる。 Conventionally, this type of temperature sensor uses a thermistor made of a thermocouple or a temperature-sensitive resistor, and generally the strength of the connection between the thermistor electrode and the lead wire and the strength due to twisting of the lead wire are not very strong. Moreover, the mounting strength and torsional strength of the tip of the thermocouple were similarly weak. Therefore,
If the temperature sensor is twisted by some external force, or if it is twisted by mistake, the lead wire or thermocouple may break or come off, and the sensor no longer functions as a temperature sensor.
