Problems solved by technology

[0003] Since the resistivity of aluminum is much smaller than that of iron, the heat generated by the eddy current of the same size is very small. At the same time, the induced eddy current at the bottom of the aluminum pan is many times larger than the eddy current at the bottom of the iron pan. overloaded and unable to work properly.
[0004] Therefore, the aluminum pan cannot be heated by the traditional induction heating method

Embodiment Construction

[0016] figure 2 For the specific implementation legend.

[0017] in figure 2 Among them, C3 and C4 form the power supply voltage divider capacitor. T1 and T2 are power tubes.

[0018] The connection point of C3 and C4 is a contact point of the power output of the induction cooker, and the connection point of T1 and T2 is the other contact point of the power output of the induction cooker. These two contacts are respectively connected to the primary of the power transformer.

[0019] The secondary coil of the power transformer is respectively connected in series with resonant capacitors C1 and C2 and then connected to the induction coil of the induction cooker. There is glass-ceramic on the induction coil of the induction cooker, and an aluminum pan is placed on the glass-ceramic.

[0020] Power on the induction cooker to work, the aluminum pan heats up normally, and the induction cooker works completely normally.

Abstract

The invention belongs to the field of electromagnetic induction heating, and discloses an induction cooker for heating an aluminum pot. Two wiring heads of a primary coil of a power transformer (B) are connected with two wiring terminals output by the induction cooker. Two wiring heads of a secondary coil of the power transformer (B) are respectively connected with one end of a resonance capacitorC1 and one end of a resonance capacitor C2 in series, and the other end of the resonance capacitor C1 and the other end of the resonance capacitor C2 are connected with two wiring heads of an induction coil of the induction cooker. The induction cooker is characterized in that the primary side of the power transformer (B) is connected with the output of the induction cooker, and the secondary side of the power transformer (B) is respectively connected with resonant capacitors C1 and C2 in series and then connected with two connector lugs of an induction coil of the induction cooker.

Description

Technical field [0001] The invention is the induction heating of aluminum pot in the field of electromagnetic induction heating. Background technique [0002] At present, commercial or domestic induction cookers only perform induction heating for pots made of ferromagnetic materials, and the protection circuit is set to detect the bottom material of the pot. For pots made of non-ferromagnetic materials, the induction cooker automatically stops working. [0003] Since the electrical resistivity of aluminum is much smaller than that of iron, the eddy current of the same magnitude generates a small amount of heat. At the same time, the induced eddy current at the bottom of the aluminum pot is many times larger than the eddy current at the bottom of the iron pot, resulting in serious current in the power tube of the induction cooker. It is overloaded and cannot work normally. [0004] Therefore, the traditional induction heating method cannot heat the aluminum pan. Summary of the inven...
