Magnetic field control circuit, plasma flame control method and device and plasma stove

Abstract

The invention relates to the technical field of cooking stoves, and discloses a magnetic field control circuit, a plasma flame control method and device and a plasma stove. The magnetic field controlcircuit comprises a mirror current source, an electromagnetic coil and a resistance adjusting module. The mirror current source comprises a first controllable switch and a second controllable switch,and the control end of the first controllable switch is connected with the control end of the second controllable switch. The first end of the first controllable switch is connected with a power supply, and the second end of the first controllable switch is grounded through a current-limiting resistor. The first end of the electromagnetic coil is connected with the first end of the second controllable switch, and the second end of the electromagnetic coil is grounded. The resistance adjusting module can output different resistance values, one end of the resistance adjusting module is connectedwith the second end of the second controllable switch, and the other end of the resistance adjusting module is grounded. Through the implementation of the magnetic field control circuit, the plasma flame control method and device and the plasma stove, the magnetic field intensity of the plasma stove is flexibly adjusted, so that adjustment of the magnitude of the plasma flame is realized, and theheat production efficiency of the stove is accurately controlled.

Description

technical field [0001] The invention relates to the technical field of cooking stoves, in particular to a magnetic field control circuit, an ion flame control method and device, and a plasma stove. Background technique [0002] Cooking stoves on the market are mainly induction cookers and gas stoves, and gas stoves occupy most of the market. However, the combustion substances required by the gas furnace are usually flammable and explosive substances, such as natural gas, coal gas, and the like. And the heat production efficiency is low, it is difficult to generate higher temperature, and it is easy to generate greenhouse gases such as carbon dioxide. In order to overcome the combustion problem of gas stoves, plasma stoves have become a new type of heating stoves because of their high heat production efficiency and energy saving. The body flame is adjusted, making it difficult to control the heat production efficiency of the plasma cooker. Contents of the invention [00...
