Description

The multiple layer metal the bottom of a pan

Technical field

The utility model relates to cook utensil technical field, particularly relates to a kind of multiple layer metal the bottom of a pan of tool multilayer composite metal structure.

Background technology

The bottom of a pan of the prior art is normally made up of single-layer metal, such as stainless steel or carbon steel.Because the bottom of a pan is in the working environment of high temperature, many salt for a long time, the poisonous metal in the bottom of a pan can be caused after stainless steel or carbon steel contact with food materials to separate out, and pollute food materials.Simultaneously the individual layer the bottom of a pan can cause the bottom of a pan heat conduction uneven, thus sticky pot occurs or the phenomenon such as to be charred.

In view of this, be necessary to be improved the bottom of a pan of the prior art, to solve the problem.

Utility model content

The purpose of this utility model is open a kind of multiple layer metal the bottom of a pan, in order to improve the heat conductivility in the bottom of a pan and effectively to prevent the poisonous metal in the bottom of a pan from separating out.

For achieving the above object, the utility model provides the multiple layer metal the bottom of a pan, comprises titanium layer, aluminium lamination, stainless steel layer, and blind hole is offered in the bottom of stainless steel layer.

As further improvement of the utility model, blind hole has multiple, is distributed in bottom stainless steel layer.

As further improvement of the utility model, blind hole is conical blind hole, and the tapering of blind hole is 5-12 degree.

As further improvement of the utility model, the internal face of blind hole has multi-turn convex ridge.

As further improvement of the utility model, the thickness of titanium layer, aluminium lamination is equal, is all less than the thickness of stainless steel layer.

As further improvement of the utility model, 1/6 of the thickness stainless steel layer thickness of titanium layer, aluminium lamination.

Compared with prior art, the beneficial effects of the utility model are: in the utility model, the multilayer composite metal Rotating fields formed by not titanium layer, aluminium lamination and stainless steel layer and be arranged on the multiple blind holes offered bottom stainless steel layer, effectively improve the heat conductivility in the bottom of a pan, prevent the problem that cooker sticky pot occurs or is charred.

Detailed description of the invention

Below in conjunction with each embodiment shown in the drawings, the utility model is described in detail; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection domain of the present utility model.

A kind of detailed description of the invention in please refer to the drawing 1 and the utility model multiple layer metal the bottom of a pan shown in Fig. 2.

In the present embodiment, the multiple layer metal the bottom of a pan 100, comprises titanium layer 10, aluminium lamination 20 and stainless steel layer 30.The thickness of aluminium lamination 20 equals the thickness of titanium layer 10, and the thickness of titanium layer 10, aluminium lamination 20 is all less than the thickness of this stainless steel layer 30.Further, the thickness of titanium layer 10, aluminium lamination 20 is 1/6 of stainless steel 30 thickness.Concrete, this titanium layer 10 is 0.5mm with the thickness of aluminium lamination 20, and the thickness of stainless steel layer 30 is 3mm.

Concrete, this titanium trade mark selected by titanium layer 10 is TA1, TA2, and the aluminum metal trade mark selected by aluminium lamination 20 is 1050,3003; The stainless steel trade mark of stainless steel layer 30 is SUS201, SUS202, SUS301, SUS304, SUS316, SUS409, SUS410, SUS430.This titanium layer 10, aluminium lamination 20 and stainless steel layer 30 can be put into after heating furnace is heated to 400-500 degree Celsius simultaneously simultaneously, move to rapidly in milling train and carry out calendering process, the final the bottom of a pan 100 forming the multilayer composite metal structure of integration after 3-5 calendering process of going forward side by side.

The bottom of this stainless steel layer 30 offers blind hole 301.This blind hole 301 has multiple, and this blind hole 301 annular spread is bottom stainless steel layer 30.Titanium layer 10 directly contacts with food materials, and the harmful metal elements avoided in stainless steel layer 30 is separated out and pollutes food materials under high temperature, hypersaline environment.

Concrete, this blind hole 301 is conical blind hole, and the tapering of blind hole 301 is 5-12 degree, and more preferably 5 degree.Along the inwall mask multi-turn convex ridge 311 of blind hole 301.By these blind holes 301 and convex ridge 311, the contact area in flame and the bottom of a pan 100 can be increased, improve heat conducting efficiency.Aluminium lamination 20 is set between stainless steel layer 30 and titanium layer 10 simultaneously, can, by the excellent heat conduction efficiency of aluminium, makes the heat-conducting effect in the multiple layer metal the bottom of a pan 100 more evenly good.

A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
