Problems solved by technology

However, the working coil of the induction cooker must be wound on the bottom of the cooker, which not only has complicated process and low production efficiency, but also affects the appearance of the cooker.
Since the working coil of the induction cooker is at the bottom of the cooker, the induction cooker will be affected by high temperature for a long time when it is working, which will cause the insulation of the coil to peel off, resulting in the failure of the coil short circuit and affecting the stability of the system.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic cooker, in particular to a wireless temperature measuring device for the electromagnetic cooker. Background technique [0002] The wireless temperature measurement method of the induction cooker has been recognized by the market for its ability to accurately measure the temperature of food. Its components generally include: induction cooker, cooking utensils, temperature measuring device, wireless sending device, wireless receiving device, battery and other components. However, based on these components, the heating state of the cooker cannot be accurately judged, and the wireless sending device cannot be turned off in time after the heating is completed, resulting in increased power consumption of the battery. In this way, how to prolong the battery life has become one of the core issues of wireless temperature measurement. [0003] For this reason, the China Invention Patent Authorizat...
