In the cooker pot frame provided by the embodiment, because the thermal conductivity of the first outer layer 110 and the second outer layer 130 is greater than or less than that of the middle layer 120, compared with the single-layer disc adopted by the upper-layer disc 100 in the prior art, when the thermal conductivity of the middle layer 120 is greater than that of the first outer layer 110 and the second outer layer 130, the first outer layer 110 and the second outer layer 130 positioned at the outer sides can reduce the heat transferred downwards, the middle layer 120 can enable the first outer layer 110 and the second outer layer 130 to be rapidly heated to be consistent, the heating is relatively uniform, the local temperature is prevented from being overhigh, the problem that the cooker pot frame is easy to deform at high temperature can be relieved, and the emission of nitrogen oxides is reduced; meanwhile, the arrangement can form dynamic balance of heat insulation and heat storage, and the cooker pot frame after heat collection can carry out heat radiation on the combustion cavity, so that the temperature of the combustion cavity is increased, and the heat efficiency is improved; when the thermal conductivity of the middle layer 120 is less than the thermal conductivity of the first outer layer 110 and the second outer layer 130, the middle layer 120 has smaller thermal conductivity, so that the thermal conduction can be effectively reduced, and further, the loss of heat of the combustion chamber is reduced, so that the temperature of combustion flame and smoke is higher, and the thermal efficiency is improved.

In addition, because the thermal conductivity of the first outer layer 110 and the second outer layer 130 is greater than or less than that of the middle layer 120, according to the selection of actual materials, the inner hole of the first outer layer 110 is bent inwards to form an inward flanging structure 111 for at least covering the inner hole edge of the middle layer 120, and the outer edge of the first outer layer 110 is bent inwards to form an outward flanging structure 112 for at least covering the outer edge of the middle layer 120, so that the parts on two sides of the middle layer 120 can be protected, the middle layer 120 is prevented from contacting with substances such as corrosion, and the corrosion resistance of the middle layer 120 is improved.

In this embodiment, the first outer layer 110 and the second outer layer 130 are made of stainless steel; the intermediate layer 120 is made of aluminum. In other embodiments, aluminum may be replaced with copper, zinc, iron, aerogel, ceramic, fiberglass, and the like.

The middle layer 120 is made of aluminum, the first outer layer 110 and the second outer layer 130 are both made of stainless steel, and since aluminum is not corrosion-resistant, if a pan overflowing phenomenon occurs, adverse effects may be caused on the middle layer 120, and the inner flanging structure 111 and the outer flanging structure 112 which are arranged in the above manner can play a role in protecting.

Both sides of the first outer layer 110 are wider than the middle layer 120, so that both sides of the first outer layer 110 are respectively rolled down to form an inner flange structure 111 and an outer flange structure 112.

Specifically, the width of the first outer layer 110 is greater than the width of the middle layer 120, and the width of the middle layer 120 is greater than the width of the second outer layer 130, so that the widened portion of the first outer layer 110 relative to the middle layer 120 can be turned downward to form the inner flange structure 111 and the outer flange structure 112.

Further, the upper disc 100 is provided with a through hole 140 penetrating the first outer layer 110 and the middle layer 120, and the through hole 140 is provided near the center of the upper disc 100.

Because the heat conductivity of aluminium is superior to stainless steel, therefore middle level 120 temperature is higher and can store the heat, and secondary air can be followed the cooking utensils pot frame bottom and passed through, gets into in the through-hole 140 and carries out the heat transfer with middle level 120, and rethread through-hole 140 flows out, because secondary air obtains preheating, consequently does benefit to the gas combustion, has improved flame temperature and thermal efficiency.

Alternatively, the through-hole 140 may be a circular hole, or a hole of other shape.

In this embodiment, the center line of the through hole 140 is parallel to the center line of the upper tray 100, i.e., vertically arranged, to ensure that the secondary air smoothly enters the through hole 140.

The specific materials of the left layer 310, the middle layer 320 and the right layer 330 can be referred to the upper disc 100.

In this embodiment, the material of left layer 310 and right layer 330 is preferably stainless steel, and the material of middle layer 320 is preferably aluminum. Compared with stainless steel, aluminum has better heat transfer performance, so that the foot piece 300 can absorb the heat of surrounding high-temperature smoke and keep constant temperature, thereby preventing local overhigh temperature of the smoke around the foot piece 300 and being beneficial to reducing the emission of nitrogen oxides NOx.

With continued reference to fig. 5, the top edge of middle layer 320 is lower than the top edges of left layer 310 and right layer 330, such that cavity 340 is defined by left layer 310, middle layer 320, and right layer 330.

The concave cavity 340 formed by the leg pieces 300 can reduce the contact area between the leg pieces 300 and the pot bottom, reduce the heat conduction from the pot bottom to the pot frame and facilitate the improvement of the heat efficiency; meanwhile, the concave cavity 340 can also be used as a smoke discharge channel, so that the smoke discharge area is increased, and the smoke discharge is facilitated.

In this embodiment, the lower surface of the lower plate 200 extends downward to form a plurality of sets of bosses 400, and the bottom surfaces of the plurality of sets of bosses 400 are coplanar for being stably placed on the gas cooker.
