Single-electrode-controllable plasma oven

Abstract

The invention discloses a single-electrode-controllable plasma oven. The single-electrode-controllable plasma oven comprises a base, one or more cooking ranges arranged on the base, and an electric control unit; each cooking range comprises a cookware support exposed above the base, and a plurality of discharge electrodes located on the inner side of the cookware support; each cooking range further comprises a high-voltage pack arranged in the base, wherein the high-voltage pack comprises a shielding shell and a plurality of miniature transformers arranged in the shielding shell in a sealed mode; and the input end of each miniature transformer is electrically connected with the electric control unit and separately controlled by the electric control unit, the output end of each miniature transformer is electrically connected with the corresponding discharge electrode, and each miniature transformer transforms low-voltage electricity input by the electric control unit into high-voltage electricity to be discharged through the discharge electrode electrically connected with the miniature transformer. Switching of each discharge electrode can be separately controlled, thus the heatingeffect of the plasma oven is accurately controlled, and meanwhile electromagnetic radiation generated by a high-frequency and high-voltage circuit in the plasma oven can be effectively shielded or restrained.

Description

technical field [0001] The invention relates to the technical field of cookers, in particular to a single-electrode controllable plasma cooker. Background technique [0002] Plasma, also known as plasma, is an ionized gas-like substance composed of positive and negative ions generated after ionization of atoms and atomic groups after partial electron deprivation. It is a macroscopically neutral ionized gas whose scale is larger than the Debye length. Movement is dominated by electromagnetic forces and exhibits remarkable collective behavior. Plasma is an excellent electrical conductor and can be trapped, moved and accelerated using cleverly designed magnetic fields. The development of plasma physics provides new technologies and processes for the further development of materials, energy, information, environmental space, space physics, geophysics and other sciences. Plasma is the fourth state of matter distinct from solids, liquids and gases. Matter is made of molecules, ...

AI Technical Summary

Problems solved by technology

[0005] 1. The multiple discharge electrodes of the existing plasma cooker are powered by a high-voltage power supply unit, so that when the power is adjusted, it is impossible to specifically control the opening and closing of a certain discharge electrode, but multiple electrodes discharge randomly to generate plasma , which makes it impossible to accurately control which discharge electrode on the bottom surface of the pot produces the ion flame, so that the heating position on the bottom surface of the pot cannot be accurately controlled, which affects the cooking quality and effect

[0006] 2. There is no reasonable structural design for the high-frequency and high-voltage power supply generation circuit required by the discharge electrode to shield or suppress the electromagnetic radiation generated by it. Long-term use will cause health hazards to users
