Problems solved by technology

[0002] At present, the induction cooker and its cooking pots (ordinary pots) have too fast temperature rise during cooking, which is easy to burn the pot, and the pot will be overheated after the water in the pot is dried out.
The main reason for the above problems is that the existing induction cooker cannot sense the temperature of the cooking pot well, and thus cannot perform cooking fire control well.
[0003] Although some cooking pots are designed with temperature sensing devices, they generally require battery power to display temperature information for user reference, and the corresponding battery replacement and charging operations are troublesome; the temperature sensing device provided by the prior art inserts the temperature sensor In the hole at the bottom of the pot, there are many layers between the food in the pot, the temperature conduction is slow, and the temperature difference is large, so the temperature information in the pot cannot be transmitted to the induction cooker and other terminals in time for heating (power) control

Embodiment Construction

[0025] In the related technology, since the induction cooker and the ordinary pot used cannot carry out accurate temperature measurement and temperature control, the temperature of the cooking pot rises too fast, it is easy to burn the pot, and it is overheated. In order to achieve automatic temperature measurement, the cooking pot (hereinafter referred to as smart pot) Sensors such as thermocouples or thermal resistances are arranged inside or outside the tool), and the sensor operation circuit, temperature display and cooker communication all require an external power supply.

[0026] The load of the smart cooker is powered by the battery, and the battery needs to be replaced or charged frequently. The battery and the load are not easy to seal, and it is easy to cause water or oil failure; the battery also occupies limited space on the handle, and the battery must be replaced or charged frequently. Charging also brings inconvenience to users; even if a temperature sensor is i...

Abstract

The embodiment of the invention discloses a pot for electromagnetic heating, a preparation method and a temperature measuring method, and the pot comprises a pot body and a load; a first insulating layer is arranged on the outer side of the bottom of the pot body, and a first coil is arranged on the first insulating layer; the first coil is used for generating electromagnetic induction with a second coil on an induction cooker during working so as to generate alternating current and supply power to a load arranged on the pot; a thermocouple is arranged on the inner side of the bottom of the pot body and used for generating corresponding thermoelectromotive force according to the heating temperature of the inner side of the pot and outputting the thermoelectromotive force to the load. The first coil is a film coil, the thermocouple is a film electrode, and the load is used for converting the thermoelectromotive force into temperature information.

Description

technical field [0001] The embodiment of the present application relates to the field of cooking utensils, and relates to, but not limited to, a pot for electromagnetic heating, a preparation method thereof, and a temperature measurement method thereof. Background technique [0002] At present, the induction cooker and its cooking pots (ordinary pots) have too fast temperature rise during cooking, and the pots are easy to burn, and the water in the pots is dried out, causing problems such as overheating of the pots. The main reason for the above problems is that the existing induction cooker cannot sense the temperature of the cooking pot well, and thus cannot perform cooking fire control well. [0003] Although some cooking pots are designed with temperature sensing devices, they generally require battery power to display temperature information for user reference, and the corresponding battery replacement and charging operations are troublesome; the temperature sensing dev...
