e. placing the three-layer composite board on a die to perform stamping and stretching to form a pot body;

f. forming a process hole by punching a counter bore at the process line on the upper side of the pot body;

g. placing the pot body on a forming die, and then inflating air at the technical hole of the pot body to enable the graphite line to expand along the outer plate to form the pot body with a completely flat middle plate and an externally bulged channel network on the outer plate;

H. cutting off waste materials with process holes on the upper ring edge of the pot body;

I. connecting an aluminum liquid injection process pipe on the process line, and filling heat-conducting liquid in the graphite line;

J. cutting off the aluminum liquid injection process pipe at the flash and the raised edge at the flash, and welding to prevent the heat-conducting liquid from leaking;

and step K is also included after the step J, and the step K is also included after the step J, the exposed surface of the pot body is cleaned, and the flash and the burr are removed.

A simplified selection of steps, said steps d and e combining to: and putting the inner plate, the middle plate and the outer plate after being attached into a die, punching and stretching to form a pot body.

When the electric cooker is used, the constant-temperature inner container of the electric cooker can be used as the inner container in the prior art, the utility model also relates to a pan and a stockpot which are made of the same structural materials, and the using method is common to the existing pan and stockpot, and is not repeated.

The utility model has the beneficial effects that: 1. the double-layer heat bag with the cavity and the bulge structure has double heat storage and greatly improved heat preservation. 2. The thermostatic pot adopts the channel network with the heat conducting liquid stored in the channel network, can store heat in the heating process and radiate the heat in the heat preservation stage, thereby increasing the heat preservation performance and reducing the power consumption in the heat preservation stage. 3. The stainless steel inner plate of the innermost layer has very good structural strength and corrosion resistance, and is very convenient to clean.
