The provision of the parts in the two portions of the pot body 10 and the heating stage 20, respectively, allows each portion to have a small volume and weight. The user only needs to move the pot body 10 after finishing cooking without moving the heating stage 20 together. Therefore, according to the utility model discloses a cooking utensil has light nimble characteristics. Further, it is also possible to provide the heating platform 20 to be adapted to the pot bodies 10 having different cooking functions, reducing the number of cooking appliances in the home.

In order to ensure the heating efficiency, the heating device 21 is configured as an electromagnetic induction heating device. Therefore, in the following description, the heating device 21 may also be referred to as an electromagnetic induction heating device 21. Specifically, the electromagnetic induction heating device 21 may be configured in the form of a coil disk. Accordingly, the inner pot 12 may be configured to be at least partially fabricated from a magnetically permeable material.

When cooking is needed, the pot body 10 is placed on the heating platform 20, the electromagnetic induction heating device 21 is powered on and generates a magnetic field, the inner pot 12 generates vortex under the action of the magnetic field, and the food or water in the inner pot 12 is heated by the heat generated by the vortex.

During cooking, the control device 23 in the heating platform 20 needs to control the electromagnetic induction heating device 21 to heat with proper power according to the temperature level in the inner pot 12. Therefore, it is necessary to measure the temperature of the inner pot 12 and transmit the measured temperature value to the control device 23. As shown in fig. 2, a temperature measuring device 22 for measuring the temperature of the inner pot 12 is disposed in the heating platform 20, and is electrically connected to the control device 23 to transmit the temperature measurement result to the control device 23.
