Plasma (plasma), also known as plasma, is an ionized gaseous substance consisting of atoms deprived of part of electrons and positive and negative ions produced by ionization of radicals, a macroscopic electrically neutral ionized gas with dimensions greater than the debye length, whose motion is dominated mainly by electromagnetic forces and exhibits a pronounced collective behavior. The plasma is a good electric conductor, and the plasma can be captured, moved and accelerated by utilizing a magnetic field which is skillfully designed. The development of plasma physics provides new technology and process for the further development of science such as materials, energy, information, environmental space, space physics, geophysical and the like. Plasma is a fourth state of matter different from solid, liquid and gas. A substance is composed of molecules, which are composed of atoms, which are composed of a positively charged nucleus and negatively charged electrons surrounding it. When heated to a sufficiently high temperature or for other reasons, the outer electrons become free electrons free from the nuclei, as if the student after class runs to the playground to play at will.

The base 1 is used for installing the cooking range 2 and the power supply control circuit 3 and plays a supporting role. The base 1 may be formed by combining upper and lower housings made of plastic.
The power control circuit 3 is used for generating a driving power required by the high-voltage package 4 and controlling the high-voltage circuit 6 in the high-voltage package 4 to be switched on and off to output power or stop power output. The driving power supply generated by the power supply control circuit 3 is a high-frequency or low-frequency low-voltage power supply, the high-voltage circuit 6 in the high-voltage bag 4 converts the low-voltage power input by the power supply control circuit 3 into high-voltage power and outputs the high-voltage power to the discharge electrode 5 for discharging, and the electric arc generated by the discharge electrode 5 during discharging ionizes air to generate high-temperature plasma to heat the bottom of the pot. In the embodiment of the invention, the power control circuit 3 is connected with an external power supply through the plug 10.

The leakage detection circuit detects whether there is leakage in the base 1, the cooking range 2, and the like, and the pot 200, and the like, and once the leakage occurs, the power control circuit 3 controls to turn off the power of the plasma cooking range 100. Thereby ensuring the use safety.
The cooking range 2 of the present invention further comprises a pot support ring 8 installed above the high pressure packet 4 and exposed from the base 1 for placing and supporting a pot 200.

The protective layer 71 is used to prevent impurities, such as water, oil, vegetables, etc., from falling into the cooking range 2 during cooking, and is difficult to clean and affect the use. While the protective layer 71 is positioned at the uppermost layer, which is directly exposed under the discharge electrode 5, the protective layer 71 can prevent a part of heat from being transferred downward. Preferably, the protective layer 71 of the present invention is microcrystalline glass.
The microcrystalline glass has the advantages of smooth and easy cleaning surface, high toughness, no fragility like common glass, wear resistance, scratch resistance, excellent insulating property, chemical corrosion resistance, good thermal stability and high use temperature. Therefore, the protective layer 71 of the present invention can protect the underlying structure by using microcrystalline glass.
Preferably, the edge of the protective layer 71 of the present invention exceeds the edge of the first arc-proof layer 72, the high-temperature-resistant insulating layer 73 and the second arc-proof layer 74 which are arranged below the protective layer, so that the first arc-proof layer 72, the high-temperature-resistant insulating layer 73 and the second arc-proof layer 74 are completely covered and protected by the protective layer 71.
The high temperature resistant insulating layer 73 is mainly used for heat insulation and prevents heat generated at the discharge electrode 5 in the cooking range 2 from being conducted to the high-voltage circuit 6 in the high-voltage bag 4 to affect the performance of the high-voltage circuit 6. Preferably, the high temperature resistant insulating layer 73 of the present invention is mica. The mica has a good heat insulation and heat resistance effect due to the multilayer laminated structure and can bear the high temperature of about 1000 ℃, so that the high-temperature-resistant heat insulation layer 73 can prevent most of heat conducted downwards and protect the circuit in the high-voltage pack 4.
Since the plurality of discharge electrodes 5 are inserted into the high temperature insulating layer 73, if the discharge arc between the discharge electrodes 5 directly acts on the high temperature insulating layer 73, the high temperature insulating layer 73 is easily damaged by the arc, which affects the service life.
According to the invention, a first arc-resistant layer 72 and a second arc-resistant layer 74 are respectively attached to the upper surface and the lower surface of a high-temperature-resistant heat-insulating layer 73. Thereby preventing the high-temperature-resistant insulating layer 73 from being damaged by the arc, which realizes both good heat insulation and prevention of arc damage.
The first arc-resistant layer 72 and the second arc-resistant layer 74 are made of special materials so that the arc-resistant layers can resist arc striking, and preferably, the first arc-resistant layer 72 and the second arc-resistant layer 74 are made of teflon plastics.

Therefore, the high-temperature-resistant heat-insulating layer 73 can be effectively protected in the high-pressure discharge process of the plasma stove 100, and the high-temperature-resistant heat-insulating layer 73 is prevented from being damaged by electric arcs.
Therefore, the single-layer electrode mounting plate in the existing plasma stove 100 is replaced by the composite insulating structure layer with the four-layer structure, so that the heat insulation effect is greatly improved, the high-temperature-resistant heat insulation layer is prevented from being damaged by electric arcs, the product quality is improved, and the service life of the product is prolonged.

Preferably, a gap is provided between the outer wall of the head 511 of the electrode connection rod 51 of the present invention and the protective layer 71; a gap is provided between the outer wall of the rod portion 512 of the electrode connecting rod 51 and the high-temperature-resistant heat-insulating layer 73. Namely, the outer side wall of the electrode connecting rod 51 and the inner wall of the through hole of the composite insulating structure layer 7 are in non-contact arrangement. Thus, when the arc generated by creepage on the electrode connecting rod 51 of the discharge electrode 5 is intended to move to the lower surface of the second arc-resistant layer 74 or to the upper surface of the protective layer 71, the arc must travel along the gap surface between the electrode connecting rod 51 and the high-temperature-resistant heat-insulating layer 73, and along the gap surface between the electrode connecting rod 51 and the protective layer 71, so that the creepage distance is increased, and creepage between the electrode connecting rod 51 and the lower surface of the second arc-resistant layer 74 and the upper surface of the protective layer 71 can be prevented, so as to protect the entire composite insulating structure layer 7.
Further, as shown in fig. 8 and 9, a centering taper portion 513 is further provided at a connection portion between the head portion 511 and the rod portion 512 of the electrode connecting rod 51 according to the present invention, and an outer wall of the centering taper portion 513 is in contact with the first arc-resistant layer 72 and the high-temperature-resistant heat insulating layer 73.
Thus, when the electrode connecting rod 51 is installed, the electrode connecting rod can be quickly aligned with the hole site penetrating through the high-temperature-resistant heat-insulating layer 73, and eccentricity is prevented. Because the outer wall of the electrode connecting rod 51 is closely attached to the inner wall of the hole penetrating through the high-temperature-resistant heat insulation layer 73 when the electrode connecting rod is eccentrically installed, the anti-creepage effect is invalid after the electrode connecting rod is closely attached.
Preferably, as shown in fig. 10, a liftable grounding probe 12 is further disposed on the insulating support 41 of the plasma cooker 100 of the present invention, the liftable grounding probe 12 is upwardly protruded with an elastically liftable protruding end 121 for elastically contacting with the bottom of the pot 200, and the protruding end 121 is electrically grounded.
When the pot 200 is placed on the plasma cooker 100, the bottom surface of the pot 200 is elastically contacted with the extending end 121 of the liftable grounding probe 12, thereby realizing good grounding of the pot 200 and ensuring safe use.
According to the plasma stove 100 with the electrode installation composite layer provided by the embodiment of the invention, a single-layer electrode installation plate in the prior art is replaced by a composite insulating structure layer 7 with a four-layer structure, the composite insulating structure layer 7 sequentially comprises a protective layer 71, a first arc-resistant layer 72, a high-temperature-resistant insulating layer 73 and a second arc-resistant layer 74, the protective layer 71 plays a role in protecting an outer cover, so that sundries in a cooking process are prevented from falling into the stove head 2, and meanwhile, the high-temperature-resistant insulating layer 73 mainly insulates heat and prevents heat from being conducted downwards to influence an internal circuit, the first arc-resistant layer 72 and the second arc-resistant layer 74 are arranged on the upper surface and the lower surface of the high-temperature-resistant insulating layer 73, the effect of preventing arc damage to the high-temperature-resistant insulating layer 73 is achieved, and the high-temperature-resistant insulating layer 73 is prevented from being damaged. The invention can prevent arc damage and has good heat insulation effect due to the arrangement of the composite insulating structure layer 7, thereby ensuring the stability of the product in use and greatly prolonging the service life of the product.
