[0047] The support assembly comprises first convex points 103 and a first retaining ring 202, the first convex points 103 are uniformly arranged on the outer circumferential side surface of the inner ring plate 1, and the first retaining ring 202 is arranged on the outer ring plate 2 and can be bent inward from the outer ring plate 2 to form. The inner ring plate 1 is formed by abutting the first convex points 103 against the first retaining ring 202 to form a heat insulation channel 4. Through the design of the first convex points 103 and the first retaining ring 202, the inner ring plate 1 and the outer ring plate 2 can be easily separated, the contact area is reduced, and the heat dissipation from the inner ring plate 1 to the inner ring of the outer ring plate 2 can be further reduced. The heat insulation channel 4 can be air-insulated or filled with heat insulation materials.

[0048] The inner ring plate 1 is of a closed structure, and the inside of the inner ring plate 1 is hollow or filled with heat insulation materials to improve the heat insulation effect and further reduce the heat loss.

[0049] The bottom of the inner ring plate 1 is provided with first air vents 105 for releasing hot air in the inner ring plate 1, which are annularly and uniformly distributed on the bottom surface of the inner ring plate 1 and penetrate through the bottom surface of the inner ring plate 1 to prevent the inner ring plate 1 from being overheated, deformed or producing abnormal noise.

[0050] The outer ring plate 2 is provided with a semi-closed heat insulation cavity 201, and the inside of the heat insulation cavity 201 is hollow or filled with heat insulation materials.

[0053] Example 2

[0054] like Figure 2 , Figures 6 to 10 As shown, this invention provides a composite furnace frame, comprising an inner ring plate 1 and an outer ring plate 2. The inner ring plate 1 is connected to the inner side of the outer ring plate 2 via a support assembly. The inner ring plate 1 and the outer ring plate 2 cooperate to form a heat insulation channel 4, reducing heat loss from the burner and improving thermal efficiency. Through the design of the above structure, the heat generated by the burner can be reduced from heat transfer to the outside by the inner ring plate 1. When the inner ring plate 1 is working, its temperature will also rise, causing heat transfer to the outside. The outer ring plate 2 then provides insulation, which can greatly reduce heat loss to the outside. The heat insulation channel 4 can reduce the contact area between the inner and outer ring plates.

[0055] The support assembly includes a first protrusion 103 and a first retaining ring 202. The first protrusion 103 is evenly distributed on the outer circumferential side of the inner ring disk 1, and the first retaining ring 202 is disposed on the outer ring disk 2. The first retaining ring 202 can be formed by bending the outer ring disk 2 inward.

The outer ring disk 2 has a second retaining ring 203, on which a support surface 205 is provided. The first retaining ring 202 extends to the support surface 205. The bottom of the inner ring disk 1 has a second protrusion 104 for supporting the inner ring disk 1. The inner ring disk 1 is supported on the support surface 205 by the second protrusion 104, so that a second vent groove 702 is formed between the inner ring disk 1 and the support surface 205. The second vent groove 702 is connected to the heat insulation channel 4. The design of the second protrusion 104 can reduce the contact area between the inner ring disk 1 and the support surface 205, further reducing the heat dissipation from the outer ring of the inner ring disk 1 to the inner ring of the outer ring disk 2.

[0059] The outer ring 2 is provided with a second vent 206 for releasing hot air from the heat insulation cavity 201 to prevent the outer ring 2 from overheating and deforming or producing abnormal noise.

The inclined surface 101 is a straight plane or a concave surface. The design of the pot feet 102 can reduce the heat loss of the inner ring plate 1. After reaching a certain level, it will radiate to the cookware, further improving the thermal efficiency.

[0061] The furnace frame also includes a support frame 3, which has at least two legs 301. An air intake channel 6 is formed between two adjacent legs 301, which can introduce outside air into the furnace frame to improve the combustion efficiency of the burner.
