Reference numeral 21 denotes a cooker main body, and a pan 22 is detachably installed inside the cooker main body 21. Reference numeral 23 is an induction coil, and 24 is a control circuit for controlling the induction coil 23. Reference numeral 25 denotes a temperature sensor, which is supported on the cooker main body by a support 26 and is urged toward the pan 22 by a support spring 27. An end turn 28 is provided on the temperature sensor 25 side of the support spring.

されている。The pan 22 provided in the cooker main body 21 is electromagnetically induced by applying a high frequency current generated by the control circuit 24 to the induction coil 23, and is induction-heated. Further, the temperature of the bottom of the pot 22 is detected by the temperature sensor 25 to control the temperature of the pot 22. The temperature sensor 25 is supported by the cooker main body 21 by a support 26 and is biased toward the pan 22 by a support spring 27.

いなければならないという問題点があった。However, in the above-described conventional configuration, when the pan 22 is heated by the induction coil 23, the end turn 28 of the support spring 27 is used.
Since the single coil forms a single coil, the end turn 28 is also induction-heated by the electromagnetic induction effect, which may affect the temperature sensor 25 and prevent the temperature of the bottom surface of the pot 22 from being accurately detected. However, there is a problem in that a high heat-resistant material must be used because the temperature (not shown) of the support base 26 that comes into contact with the end turn 28 is high.

のコイル部を相互に接触しない構造としたものである。Means for Solving the Problems In order to achieve the above object, a first means of the present invention is a cooker main body, a pan detachably housed in the cooker main body, and electromagnetic induction heating of the pan. An induction coil and a control circuit, a temperature sensor for detecting the temperature of the pan, a support base for supporting the temperature sensor on the cooker body, and a biasing of the support base and the temperature sensor on the pan side. The support spring has a structure in which the coil portions on the temperature sensor side do not contact each other.
第２の手段は、支持バネの温度センサ側の座巻きをな

価な材料を用いる必要がなくなる。Action According to the above configuration, since the support spring has a structure in which the temperature sensor side coil portions do not contact each other, the spring is not electromagnetically heated even when the pan is electromagnetically heated by the induction coil.
Since the temperature does not become high, the temperature sensor is not affected, and the temperature of the pot bottom can be detected more accurately by the temperature sensor. Moreover, since the temperature of the portion of the support table that contacts the temperature sensor does not rise, it is not necessary to use an expensive material having high heat resistance.

になっている。The pan 2 provided inside the cooker main body 1 causes electromagnetic induction by applying a high-frequency current generated by the control circuit 4 to the induction coil 3 and is induction-heated. At that time,
The temperature sensor 5 detects the bottom surface temperature of the pan 2 and controls the temperature of the pan 2. The temperature sensor 5 is supported by the main body by the support base 6 and is pressed by the support spring 7 to the pan 7. It is energized. Next, a method of fixing the support base 6 and the support spring 7 will be described below. Support spring 7
Has no end turn on the temperature sensor 5 side and is still in the shape of a spring, and an L-shaped 9 is provided at its end in the horizontal direction toward the center of the circle. Further, the spring receiving portion 8 of the support base 6 is not horizontal, but is configured to receive the support spring 7 by forming a spiral shape, which stabilizes the operation. Further, the support spring 7 has an L-shape 9 and a support base 6
The support spring 7 is fixed to the support base 6 by being inserted into the hole 10 provided in the spring receiving portion 8 so that the support spring 7 cannot be easily removed.
