Description

Inner-aluminum-outer-steel composite double-layer cooker

Technical Field

The utility model relates to an inner aluminum and outer steel composite double-layer cooker.

Background

The traditional single-layer stainless steel double-bottom product has no heat conduction material on the upper wall outside the pot body, so that the pot body is heated unevenly, food is heated unevenly, oil smoke is easily generated, the food is easily burnt and burnt during cooking, the health of human bodies is harmed, although the three-layer material structure can solve the problems, but is influenced by the composite processing technology, the areas of the materials on the inner surface and the outer surface of the pot body are the same, the thickness of the pot body is the same, thus causing the problems of material waste, high processing cost, high product sale price, heavy pot body, pot sticking, yellowing and discoloration of the pot body after heating, and the like, therefore, the current cooker products can not meet the main stream of times of modern people pursuing nutrition, health, green, energy-saving, environmental protection, convenience, practicability and low cost, and some cookers adopt a double-layer structure, but the pot body can be deformed at high temperature by the structure, and the problem that the pot cannot be used is caused.

The notice number is CN202919904U discloses a novel multi-element composite cooker, which comprises a cooker body and a handle, wherein the cooker body is formed by compounding an inner layer cooker body layer and an outer layer cooker body layer, the inner layer cooker body layer is a metal layer made of any one material of iron, stainless steel, titanium and titanium alloy, a cyclone type and a duct type concave-convex groove are pressed on the outer surface of the cooker body, an anti-slip energy-saving step-shaped thread is formed, and the heating area of the cooker body is increased.

However, the structure does not change the mechanical structure of the material, so that the material can be seriously deformed in the heating use process.

Disclosure of Invention

The technical problem to be solved by the utility model is to provide a light and non-deformable inner aluminum and outer steel composite double-layer cooker.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a compound double-deck cooking utensil of outer steel of interior aluminium, includes the pot body, the pot body constitute by the inlayer pot body and outer pot body, the material of the outer pot body be iron or nonrust iron, the material of the inlayer pot body be aluminium or aluminum alloy, the outer pot body on seted up one at least and cut and wear extremely the groove of cutting of the inlayer pot body, the groove of cutting be the ring form, the groove of cutting separate into a plurality of sections that the width equals with the inlayer pot body.

The utility model discloses a further preferred scheme does: the cutting groove is arranged on the side wall or the bottom surface of the outer pot body.

The utility model discloses a further preferred scheme does: the number of the cutting grooves is 4, wherein 2 cutting grooves are arranged on the side wall of the outer layer pot body and divide the outer layer pot body into three sections with equal height, and the rest 2 cutting grooves are arranged on the bottom surface of the outer layer pot body and divide the outer layer pot body into three sections with equal width.

The utility model discloses a further preferred scheme does: the cutting groove on the side wall of the outer pot body is internally provided with a temperature sensing color changing indicating coating.

The utility model discloses a further preferred scheme does: the surface of the inner layer pot body is coated with a non-stick coating or a ceramic coating.

Compared with the prior art, the utility model has the advantages of including the pot body, the pot body comprises the inlayer pot body and the outer pot body, the material of the outer pot body is iron or nonrust iron, the material of the inlayer pot body is aluminium or aluminum alloy, at least, set up one on the outer pot body and cut off the groove to the inlayer pot body, it is the ring form to cut off the groove, cut off the groove and separate into a plurality of sections that the width equals with the inlayer pot body, because the thermal energy concertina ratio of stainless iron is greater than the thermal energy concertina ratio of aluminium, the outer pot body that the material can take place to warp for the stainless iron after the pot body is heated, consequently cut off the outer pot body, the vertical pulling force of stainless iron can't form the complex body after the pot body is.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in the figure, the composite double-layer cooker comprises a cooker body, wherein the cooker body is composed of an inner layer cooker body 1 and an outer layer cooker body 2, the outer layer cooker body 2 is made of iron or stainless iron, and the inner layer cooker body 1 is made of aluminum or aluminum alloy.

The bottom surface or the side wall of the outer layer pot body 2 is provided with 4 cutting grooves 21 which penetrate through the inner layer pot body 1, the cutting grooves 21 are annular, wherein 2 cutting grooves are arranged on the side wall of the outer layer pot body 2 and divide the outer layer pot body into three sections with equal height, namely, a circle of cutting grooves are arranged around the side wall of the outer layer pot body 2.

The rest 2 cutting grooves are arranged on the bottom surface of the outer layer pot body 2 and are divided into three sections with equal width, namely the distance from the cutting grooves 21 on the bottom surface to the center of the bottom surface is different.

Because the thermal expansion ratio of the stainless iron is larger than that of the aluminum, the outer pot body made of the stainless iron can deform after the pot body is heated, so that the outer pot body 2 is cut off, and the longitudinal tension of the stainless iron cannot form a united body after the pot body is heated, so that the deformation can be eliminated and prevented.

A temperature sensing color changing indicating coating is arranged in the cutting groove 21 on the side wall of the outer layer pot body 2, and a non-stick coating or a ceramic coating is coated on the surface of the inner layer pot body 1.

The number of the cutting grooves is proper according to the height, the size and the actual requirement of the pot body.

The pot body is various cookers such as a frying pan, a deep frying pan, a soup pan, a milk pan and the like with the diameter, the height and the thickness not limited.
