In this embodiment, as shown in fig. 1 to 3, the inner pan 1 includes an inner pan bottom wall 2 and an inner pan side wall 3 connected to the inner pan bottom wall 2. The bottom wall heating assembly is used for heating the inner pot bottom wall 2, and the side heating assembly 20 is used for heating the inner pot side wall 3. The inner pot side wall 3 is provided with a heat conducting cavity 4 which extends along the circumferential direction of the inner pot 1 and is annular. The heat conducting cavity 4 is hollow, and is filled with a heat conducting medium with good heat conducting performance. Further, the heat conducting cavity 4 is formed with an annular medium channel 9, and the medium channel 9 is filled with a heat conducting medium.

And then the heat loaded by the heat conducting medium is transferred to the inner pot side wall 3, so that the inner pot side wall 3 is quickly heated, and the food in the inner pot 1 is heated in an auxiliary way.

The side heating means 22 heats a small part of the side of the inner pan 1, and does not need to heat the side of the inner pan 1 in a whole circle, so that the temperature of the side of the inner pan 1 in the circumferential direction is approximately uniform, and the energy consumption cost is saved. And can control the lateral part heating alone, reach expected lateral part heating temperature to and with bottom heating combined action, make whole interior pot 1 heat evenly, thereby food is heated more evenly, and the heating effect is good, guarantees that the food taste of the inboard portion department of pot is better.

The release layer 33 may be connected to one of the outer metal layer 32 and the inner metal layer 31, and the medium channel 9 within the heat conduction cavity 4 is formed between the release layer 33 and the other of the outer metal layer 32 and the inner metal layer 31. In the embodiment shown, the outer metal layer 32 protrudes outwards at the inner pot side wall 3. The release layer 33 is connected to the inner metal layer 31 and the medium channel 9 in the heat conducting cavity 4 is formed between the release layer 33 and the outer metal layer 32. The release material is applied before the two metal sheets forming the inner metal layer 31 and the outer metal layer 32 are combined so that the two metal sheets are not combined together at the release material, which facilitates separation of the two by inflation to form the heat conducting cavity.

The manufacturing process of the inner pot 1 is schematically as follows:

and compounding the two cut metal sheets together through a high-temperature compounding process. The two metal sheets may be the same or different, for example may both be aluminium sheets. Before the compounding, a release material is coated on one of the two metal sheets according to the position and shape of the preset heat conduction cavity 4, preventing the two metal sheets from being joined together at the position where the heat conduction cavity 4 is formed when the compounding is performed. The release material may be any suitable material such as graphene. And a blow-up inlet is provided at the location where the release material is applied.

The compounded metal sheet is punched and stretched into the shape of the inner pot 1. After stretch forming of the inner vessel 1, the two metal sheets are separated along the path of the release material to form an outwardly protruding heat conducting cavity 4, which is inflated via an inflation inlet. A heat conducting medium such as water, alcohol is then injected into the heat conducting cavity 4 via the inflation inlet. And finally sealing the inflation inlet. The sealing can be made by laser welding, high-temperature compounding, argon-fluorine welding and other processes.

In the case of the side coils and/or the bottom coil 12, after inflation is completed, a magnetically permeable layer is provided on the outer surface of the inner pot 1, for example by means of meltblowing. The inner pot 1 is provided with a magnetic conduction layer which can be matched with the side coil to heat the heat conduction medium, so that the side part of the inner pot 1 is heated in an auxiliary way.
