Introduction of Special Components for Induction Cooker
1. Ceramic panel
Ceramic plate is the abbreviation of microcrystalline ceramic plate. The main function of the ceramic plate is to carry the heating pot. The performance of the ceramic plate is much higher than that of ordinary ceramics. It not only has good mechanical strength, can fully bear the weight of the pot and food, but also has a certain degree of thermal shock resistance, and can withstand drastic changes in temperature.
2. Heating coil
The heating coil is an important element in the induction cooker. It has a special shape. The heating coil is also called a heating coil. It is not a heat source, but an inductance in a high-frequency resonance circuit, so it is also called a high-frequency resonance coil.
The diameter of the heating coil (except the edge of the fixed plastic disk, generally between 16cm-22cm. The center of the heating coil is installed with a temperature sensor bracket to install the thermistor. There are multiple magnetic strips on the back of the heating coil. The installation of the magnetic stripe array is In order to converge and absorb the magnetic field lines, reduce the leakage of the magnetic field lines.
3. IGBT tube
In the induction cooker circuit, the switch tube plays a very important role. When the switch tube is turned on, +300V charges the heating coil through the heating coil and the switch tube, and the electric energy is converted into electromagnetic energy in the heating coil. At this time, the voltage applied to the switch tube is about +250V, and the working current is between 20A and 40A. between.
4. Full bridge rectifier
Although the rectifier full bridge can be seen everywhere in home appliances, the rectifier full bridge used in the induction cooker requires a large output current, strong resistance to large currents, and high peak reverse voltage. For example: RS1507 rectifier full bridge, the maximum peak reverse voltage that the full bridge can withstand is 1000V; the maximum output current is 15A; the peak current can reach 250A, the maximum forward voltage drop is 1V; the operating temperature range is -55—+150.
