In the electric fire stove, the hole between the plasma needle of the plasma component 22 and the second inserting hole 203 of the insulating protective layer 23 is sealed by the sealing element 6, so that the heat generated by the plasma needle part protruding out of the insulating protective layer 2 can be prevented from being transferred to the support 1 through the hole of the second inserting hole 201, and the support 1 is deformed or the thermal stability of the lower structure of the burner component is influenced. Consequently, set up sealing member 5 on the hole of insulating protection layer 2 at furnace end assembly, can effectively improve furnace end assembly's heat-proof quality, reduce the heat and carry out the transmission through the plasma needle, avoid the air to influence the use in entering into combustion space through the hole simultaneously, guarantee combustion effect, extension furnace end assembly's life.

As shown in fig. 8 and 10, in the present embodiment, the plasma needle assembly 22 includes a first plasma needle assembly 221 and a second plasma needle assembly 222, the first plasma needle assembly 221 includes at least one first plasma needle, the first plasma needle assembly 221 is located at the center of the rack 21, the second plasma needle assembly 222 includes a plurality of second plasma needles, the second plasma needle assembly 222 is disposed around the first plasma needle assembly 221, a height of the first plasma needle assembly 221 from a support plane of the rack 21 is a first height, a height of the second plasma needle assembly 222 from the support plane of the rack 22 is a second height, and a height difference is formed between the first height and the second height.

In the above-mentioned electric fire range, two sets of plasma needle assemblies are respectively disposed on the rack 21, and the height of the first plasma head of the first plasma needle assembly 221 relative to the supporting plane of the rack 21 is greater than the height of the second plasma head of the second plasma needle assembly 222 relative to the supporting plane of the rack 21. Therefore, the spacing distance between the first plasma head and the cookware is smaller than that between the second plasma head and the cookware. When the pan was used, highly higher more easily with the pan production effect carry out high-pressure breakdown air apart from the support plane, can regulate and control the heating effect through control power, realized the controllable of heating. Therefore, the structure can generate two different heat efficiencies for heating the cookware, can meet the heating efficiency requirements of different cooking scenes on the electric cooking stove, and is high in flexibility and convenient to use.
