Abstract

The utility model discloses a complex steel pot used for an electric rice cooker or an electric pressure cooker, which comprises a cooker body (1) with an upper bent supporting edge (5) and has the key points that a high thermal conductivity metal layer (2) is pressed or welded at the outer bottom of the cooker body and extends to the lower side position on the external wall of the cooker body, and an additional protecting layer (3) is compounded or coated outside the high thermal conductivity metal layer (2). The complex steel pot used for an electric rice cooker or an electric pressure cooker solves the deficiencies that the cooker body is easy to scorch or cook food unevenly due to the facts that the cooker body has a small heating area and the steel material has a slow thermal conduction and needs no integral compound of the cooker body to waste materials. The complex steel pot used for an electric rice cooker or an electric pressure cooker has the characteristics that the operation is convenient, the heating area for the cooking position of the cooker body is enlarged, the energy is saved, the structure is simple and the material is saved.

Description

One species complex steel pot

Technical field

The utility model relates to a species complex steel pot, particularly relates to pot in the complex that is used for electric cooker or electric pressure cooking saucepan.

Background technology

Pot in electric cooker inner container or the employed steel of electric pressure cooking saucepan, all use in the bottom of pot body at present and contact with heat conducting element, but because the volume of pot body is subjected to the volume restrictions of electric cooker, the bottom area of steel inner pan body has certain limitation, cause the contact area of pot body and heating less, heat conductivility is not high, often cause the waste of the energy easily, simultaneously owing to have only the bottom of pot body to contact with heat conducting element, have the pot bottom of body of steel material and the sidepiece inequality of being heated, the conduction of steel material heat is slow, and particularly pot wall and the bottom of a pan two parts temperature difference are bigger, cause the bottom to burn meal and the top underdone defective of meal easily, and have the inadequate deficiency of using energy source.

Summary of the invention

The purpose of this utility model is to provide a kind of increase heating surface area, saves the complex steel pot of the energy.

The utility model complex steel pot comprises that top bending supports the pot body on edge, and key is to have one deck high-thermal conductive metal lamination to close or be welded on the external bottom of pot and extend to the external wall lower position of pot, also is provided with layer protective layer in the outside of high-thermal conductive metal layer.Described protective layer can be at the outside of high-thermal conductive metal layer compound layer of aluminum material protection layer; Also can apply one deck heat-conductive coating in the outside of high-thermal conductive metal layer.Wherein pot external wall, metal level, aluminum protective layer is connected to annular recess or tongue pressing and fixing; For the globality of pot body and attractive in appearance, inwardly strike out recess on the position of corresponding pressing of pot body or welding heat-conducting metal layer, pressing or weld metal layers and protective layer on recess, make the size of the lateral surface of pot body keep one to; In order to increase bottom area, the bottom of compound layer of metal protective layer is the screw-like bottom structure or is the reticulate pattern bottom structure on the heat-conducting metal layer outside.Better in order to guarantee heat conductivility, described metal composite layer material is for adopting heat conduction and the preferable metals of heat distribution performance such as aluminium or clad aluminum, copper.

The utility model is in the bottom of a pan and the lower position pressing layer of metal composite bed of pot wall, and the bottom that makes pot body all is subjected to identical heat conduction with sidepiece, increases heating surface area, increase the temperature of pot body sidewall, reduce the bottom of pot body and the temperature difference of sidepiece, guarantee to be heated evenly, improve efficiency of utilization.In order to save the material and the energy and to improve good heat conduction, the recombination site of pot body sidewall is the position of common splendid attire rice to be cooked.

The specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

Specific embodiment one

The utility model is made up of the pot body 1 and the metal composite layer 2 of steel material, comprises that top bends the pot body that supports along 5.The material of metal composite layer 2 is heat conduction and the preferable aluminium of heat distribution performance; be positioned at the skin of pot body 1; only limit to the pot wall position of the bottom of a pan and pot body 1 bottom with the pressing position of pot body 1; the diameter of the bottom of pot body 1 is less than the upper part diameter of pot body 1; it is one stepped that top and the bottom form; metal composite layer 2 is compounded in the recess location 11 of the bottom of pot body 1, at the outside of metal composite layer compound again layer of aluminum material protection layer 3 or coating one deck heat-conductive coating protective layer 3.Because the hot property of metal composite layer 2 is relatively good, thus the part that its covers be heated evenly, and people generally to cook also all be below the position, to have avoided burning easily the drawback of meal at this like this.Have only the bottom and the external wall lower position of pot of pot body that metal composite layer is arranged, increase heat transfer area, thermal efficiency height.

Specific embodiment two

The utility model by pot body 1, metal composite layer 2, aluminum protective layer 3 form.The material of metal composite layer 2 is heat conduction and the preferable aluminium of heat distribution performance, is positioned at skin, only limits to pot external wall position of the bottom of a pan and pot body 1 bottom with the pressing position of pot body 1, the pressing last layer aluminum protective layer 3 again in the outside of metal composite layer 2; Annular recess 4 of junction punching press of metal composite layer 2 edges and aluminum protective layer 3 and pot body 1 utilizes the distortion fixing metal composite bed 2 and the aluminum protective layer 3 of metal material.The bottom of a pan part of aluminum protective layer 3 adopts reticulate structure 31, compare heating surface area with the bottom of a pan, plane and increased about 30%, more efficient use the heat of bottom heat-generating disc, and more attractive in appearance.
