Background

Disclosure of Invention

The present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide an electric heating cooking utensil, a heat superconducting container and a manufacturing method thereof, which have high heat transfer efficiency and do not increase the weight of the cooking container.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the invention relates to a heat superconducting container, which is a drawing-formed bottomed cylindrical container, and at least comprises a first metal layer and a second metal layer, wherein the second metal layer is arranged on the outer side of the first metal layer, and the first metal layer and the second metal layer are hot-pressed and compounded into an inseparable composite structure before drawing forming; and a heat transfer vessel is formed between the first metal layer and the second metal layer, and the heat transfer vessel contains a heat superconducting medium.

The technical scheme can be further improved by the following measures:

further, the heat transfer vessel is formed by blowing by injecting a blowing medium along a preset forming path. And a temperature-resistant isolation layer is preset on a forming path of the first metal layer and/or the second metal layer for forming the heat transfer vessel, and the temperature-resistant isolation layer can keep the forming path from being hot-pressed and compounded in the process of hot-pressing and compounding the first metal layer and the second metal layer.

Further, the forming path is in communication with a blowing inlet provided on the vessel wall, along which a blowing medium injected by the blowing inlet flows to blow the forming path into a heat transfer vessel between the first metal layer and the second metal layer.

Further, the temperature-resistant isolation layer is preset on the first metal layer and the second metal layer or on one of the first metal layer and the second metal layer before hot-pressing compounding, and after the hot-pressing compounding of the first metal layer and the second metal layer, the first metal layer and the second metal layer are isolated from each other in the area with the temperature-resistant isolation layer and are not compounded. The melting temperature of the temperature-resistant isolation layer is higher than that of the first metal layer and the second metal layer.

Further, the inflation medium is high-pressure gas or high-pressure liquid, and the thermal superconducting medium is a refrigerant. The heat superconducting medium is injected into the heat transfer vessel after being formed into vacuum in the heat transfer vessel.

Further, the heat transfer vessel is wrapped on the side wall and/or the bottom wall of the superconducting container in a spiral shape, a grid shape or a laminated annular shape. The heat transfer vessel is formed by blowing after the heat superconducting container is deep-drawn. The cross-sectional area of the heat transfer vessel is less than 8.0mm². The second metal layer is more easily blown to deform than the first metal layer, and the second metal layer deforms prior to the first metal layer when a blowing medium is injected so that the heat transfer vessels stand out on the second metal layer.

S03, stacking the first metal layer and the second metal layer, and hot-pressing and compounding the first metal layer and the second metal layer into an inseparable composite structure;

s04, drawing and forming the semi-finished product prepared in the step S03 into a cylindrical container;

Further, in step S02, the temperature-resistant isolation layer is pre-disposed on the first metal layer and/or the second metal layer by printing.

Further, in step S05, the inside of the cylindrical container is provided with a profiling mold which is in close contact with the inner wall of the cylindrical container to prevent the heat transfer vessels from showing up on the first metal layer.

Further, in step S05, the outer circumference of the cylindrical container has a pressure field formed by the auxiliary medium, and the pressure field acts on the outer wall of the cylindrical container with a pressure lower than the pressure of the inflation medium.

Further, the auxiliary medium is high-pressure gas or high-pressure liquid.

Further, in step S07, the inflation inlet is cut off and welded closed.

Further, the execution order of step S01 and step S02 may be reversed, and steps S03 to S07 are performed in order.
