[0022] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see Figs. 1-2 In this embodiment of the utility model, an electric flame stove includes a stove body 1, a burner head 2 disposed on the top surface of the stove body 1, a furnace chamber 3, and multiple plasma burners 4.

[0025] The burner head 2 is a circular shape with an internal cavity. The plasma burner 4 is located inside the cavity of the burner head 2 and extends upward through the top surface of the burner head 2. When the electric flame stove is in working condition, the plasma burner 4 is connected to high-voltage direct current and continuously sprays plasma flames to heat the pot above.

[0026] The furnace chamber 3 is arranged in a ring shape around the burner head 2, with its top surface being circular and on the same plane. When the cookware is placed on the top surface of the furnace chamber 3, it can almost form a closed state with the top surface of the furnace chamber 3. According to the principle of thermal convection, hot gas does indeed generate upward buoyancy due to its decreasing density. When the plasma flame heats the cookware, the hot gas tends to rise, but because the cookware and the top surface of the furnace chamber 3 are almost closed, the hot gas is obstructed during its ascent. It's like setting up a "ceiling" for the hot gas, preventing it from quickly dissipating into the external environment of the furnace chamber 3. The furnace chamber design of this utility model increases the time that heat accumulates at the bottom of the cookware, extending the residence time of heat within the furnace chamber 3.

[0027] The longer the heat stays in the furnace chamber 3, the more heat the cookware can absorb, allowing the cooking process to reach the ideal temperature at a relatively low power.

[0028] Although the cookware and the top surface of the furnace 3 are almost completely sealed, there is a gap at the bottom of the furnace 3. When the plasma burner 4 is working, on the one hand, it generates plasma through ionization and other processes and ejects flames, causing the gas inside the furnace 3 to expand rapidly due to heat. On the other hand, the power of the flame ejection also compresses the air inside the furnace 3. These two factors together cause the gas pressure inside the furnace 3 to continuously increase, forming a relatively high-pressure state.

[0029] The gap at the bottom of the furnace chamber 3 provides an ideal exhaust channel. Most of the heat inside the furnace chamber 3 is transferred to the cookware as expected, while the exhaust gas is discharged from the furnace chamber 3 in a timely manner, ensuring that a sufficient pressure difference is formed between the inside of the plasma burner 4 and the inside of the furnace chamber 3, so that the plasma flame can be stably sprayed towards the bottom of the cookware.

[0030] The bottom of the combustion chamber 3 is equipped with multiple threaded screws 5 that allow for height adjustment. Support feet 6 are mounted on the bottom of each screw 5, contacting the top surface of the burner head 2. The threaded screw design allows for easy adjustment of the combustion chamber 3's height. By rotating the screws 5, the distance between the combustion chamber 3 and the burner head 2 can be precisely changed. When using cookware of different sizes or shapes, such as woks, frying pans, or iron plates, users can raise or lower the combustion chamber 3 according to their needs, ensuring better contact between the cookware and the flame for optimal cooking results. For shallower cookware, the combustion chamber 3 can be lowered to bring the flame closer to the center of the bottom; while for deeper cookware, the combustion chamber 3 can be raised to ensure the flame covers the entire bottom of the pan.

[0031] In the next embodiment, the furnace chamber 3 is at least 200mm high, which creates a relatively large space under the cookware to accommodate heat. The larger space also makes the heat distribution more even, avoiding local overheating, and the cookware can absorb heat better.

[0032] In the next embodiment, the furnace chamber 3 is made of ceramic material with low thermal conductivity. The ceramic furnace chamber 3 acts as a "thermal insulator", which can greatly reduce the heat loss to the outside through the furnace chamber 3 wall, so that more heat is absorbed by the cookware and the cooking efficiency is improved.

[0033] Meanwhile, the ceramic furnace chamber 3 also functions as a heat storage container. After heat is transferred into the ceramic furnace chamber 3, it is difficult for the heat to be quickly conducted away through its walls, so it gradually accumulates inside the furnace chamber 3, "locking" in the heat and forming a heat reserve within it. After the electric flame stove stops working, the heat stored inside the furnace chamber 3 radiates to the cookware, allowing the cookware to continue to receive heat even after the electric flame stove stops working, which helps reduce energy waste.

[0034] Plasma flames often carry a positive charge that can be conducted to cookware. When a person touches a pot carrying this charge, it can cause an electric shock. Therefore, the outer surface of the furnace chamber 3 is coated with a metal layer, and this metal layer is connected to a ground wire, effectively eliminating the potential electrical hazards posed by the plasma flame.

[0035] In the next embodiment, the number of plasma burners 4 is at least 100 to meet the high power output requirements of the electric flame stove. Multiple plasma burners 4 are evenly distributed within the furnace chamber 3 on the top surface of the burner head 2.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
