1、 Heating principle
The heating principle of an induction cooker is based on the principle of electromagnetic induction. When alternating current passes through the coil of an induction cooker, an alternating magnetic field is generated. This magnetic field will interact with the metal pot placed on the induction cooker, causing the bottom of the pot to quickly heat up. Due to the insulation material between the bottom of the pot and the induction cooker, there will be no electric sparks generated. At the same time, due to the heating of the pot bottom, heat is transferred to the food through the pot bottom, making the food evenly heated.
2、 Power circuit
The power circuit of the induction cooker is mainly divided into two parts: input circuit and output circuit. The input circuit receives mains power and filters and stabilizes the input current through devices such as fuses and filters to ensure the stable operation of the output circuit. The output circuit converts the processed electrical energy into thermal energy, converts electrical energy into magnetic field energy through a heating coil, and then converts magnetic field energy into thermal energy through a metal pot.
3、 Temperature control circuit
In order to ensure the safe and reliable operation of induction cookers, many induction cookers are equipped with temperature control circuits. The circuit mainly includes components such as temperature sensors, control chips, and thermal interrupters. The temperature sensor is used to monitor the heating temperature of the electromagnetic furnace and convert the temperature signal into an electrical signal to be transmitted to the control chip. The control chip controls the heating process based on the preset temperature value, and automatically cuts off the heating power supply and stops heating when the temperature reaches the preset value. A thermal breaker is an overheating protection device that automatically cuts off the power supply when the temperature of the induction cooker is too high, preventing equipment damage and the occurrence of fire accidents.
4、 Other functions
In addition to basic heating functions, modern induction cookers also have various other functions, such as timing, reservation, and firepower regulation. These functions cannot be separated from the application of electronic technology. For example, the timing function can be achieved by setting an electronic clock; The reservation function can be achieved through preset programs; The adjustment of firepower can be achieved by controlling the power of the heating coil.
In short, an induction cooker is a kitchen appliance that uses the principle of electromagnetic induction to heat food. Its working principle mainly includes heating principle, power circuit, and temperature control circuit. By understanding these parts, we can better understand the working principle and usage methods of electromagnetic furnaces. Meanwhile, for consumers, choosing a reliable and fully functional induction cooker is also particularly important.
