Induction cooker is a household appliance that is very commonly used in our daily life. It can help us make delicious food. Induction cooker is not like gas, which is easy to leak and does not produce open flames. It will not become an incentive for accidents. Its safety , Efficiency is also favored by many families. As an important component in the induction cooker, the NTC thermistor is particularly important. The quality of the thermistor also directly affects the safety of the induction cooker. Many people do not understand the thermistor of the induction cooker. Today, Xiaobian will introduce you to the induction cooker. The NTC thermistor used.
The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the alternating current is used to pass through the coil to generate an alternating magnetic field whose direction changes continuously. Eddy current will appear inside the conductor in the alternating magnetic field, which is the eddy electric field that pushes the current in the conductor. It is caused by the movement of the particles; the Joule heating effect of the eddy current causes the conductor to heat up, thereby achieving heating. In the heating process, an NTC thermistor needs to be used to transmit the heat signal to the control circuit, so as to measure and control the temperature, which can prevent the induction cooker from overheating, ensure the safety of use, and save electricity.
The NTC thermistor used in the induction cooker is most suitable for the glass encapsulated thermistor with a resistance value of 100KΩ, which can be used in a high temperature and high humidity environment, and the working temperature can be as high as 200 degree . important role, so the quality stability and reliability of NTC thermistors are very important
