Description

Technical Field

[0001] The utility model specifically relates to an electric flame cooker. Background Art

[0002] The DC high voltage supplied to the plasma generator by the electric flame stove is generated by a transformer and several rectifier circuits. The transformer first transforms the input voltage into an AC high voltage of several thousand volts, and the AC high voltage is then connected to several groups of voltage doubling circuits to output the DC high voltage to the positive electrode.

[0003] In the current existing technology, more than ten plasma generators are connected by one high-voltage transformer, so the load is large, which can easily cause the high-voltage transformer to overheat. When the high-voltage transformer overheats, the protection circuit will forcibly cut off the power, causing the electric flame stove to stop working, affecting the user's normal use of the electric flame stove; when adjusting the power, it is impossible to specifically control the conduction and shutdown of a certain plasma generator, so that the plasma flame cannot be accurately controlled, and thus the heating position of the bottom of the cookware cannot be accurately controlled.
