Abstract
The invention belongs to a kitchen ware with a multilayer metal composite bottom structure, and particularly relates to an inner pot of an electric cooker with a double-layer metal composite layer. The composite layer inner pot comprises a stainless steel inner layer and an aluminum outer layer, and is characterized in that the stainless steel inner layer and the aluminum outer layer are respectively formed by punching and then compounded into the pot, the joint surfaces of the stainless steel inner layer and the aluminum outer layer are respectively ground, then are superposed together for hot dipping treatment and then are rolled to be combined into the pot, and the compounding process adopts a solid-solid metal compounding process. The inner pot of the electric cooker has the characteristics of simple processing technology, high finished product qualification rate and production rate and low energy consumption cost, and the inner pot has good heat conductivity and good rice cooking effect through verification, and has no problem of coating peeling because the inner layer is made of stainless steel, is easy to clean, has good acid resistance and long service life.
Description
Technical field
The present invention relates to a kind of multilayer metal compound bottom structure kitchen tools, it is relevant with kitchen tools, particularly with have the double-level-metal composite bed in the pot electric cooker relevant.
Background technology
Pot adopts aluminium to make mostly in the existing electric cooker, and the non-sticking lining of portion's spraying within it, and major defect is that coating easily comes off, and in use can discharge harmful aluminium ion, and long-term the use impairs health.In addition, also having the interior pot of a small amount of electric cooker on the market is to adopt the stainless steel material of individual layer to make, be pot distortion in preventing, the individual layer stainless steel can not be done too thinly, so the heat conductivity of pot is bad in this kind, in the process of using, can not guarantee homogeneous heating, so that the appearance part is sallow or the phenomenon of part half-cooked rice.
For overcoming the shortcoming of aluminum pot, stainless-steel pan, bring into play strong point separately, prior art has been developed bilayer or the multi-layer metal composite material pot kitchen tools that aluminium combines with stainless steel or other metal.
At present, the processing of conventional composite pot generally is to adopt the composite plate that has processed, by direct punch forming is the pot body, because the expansion and contraction of the different materials of composition pot body is different, in the punch process process, the binder course of different materials might produce relative motion, causes between two layers of material can to produce the gap and heat conduction is bad.The processing method of conventional composite plate generally is to adopt explosion method, rolling or blast-rolling combination, and up-to-date processing method is the combination of liquid-solid phase sandwich rolling process both at home and abroad, and technology all is comparatively complicated, and energy consumption cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of NEW TYPE OF COMPOSITE inner pan of electric cooker, described inner pan of electric cooker long service life has good heat conductivity, in use can guarantee homogeneous heating, can avoid occurring the phenomenon of local sallow or part half-cooked rice.
The technical solution adopted in the present invention is: a kind of inner pan of electric cooker, and it comprises stainless steel internal layer and aluminium skin, it is characterized in that, described stainless steel internal layer and aluminium skin are to be combined into pot again after the first respectively punch forming.
The stainless steel internal layer of described inner pan of electric cooker and the outer field faying face of aluminium are to handle through frosted respectively earlier, are superimposed then to carry out hot-dip and handle and carry out roll compacting again and be combined into pot.
Another object of the present invention is to provide a kind of method of making pot in the above-mentioned NEW TYPE OF COMPOSITE layer electric cooker, it comprises the steps:
A. with corrosion resistant plate and aluminium sheet by mould and forcing press respectively punching stretch become stainless steel internal layer pot and the outer pot of aluminium.
B. the faying face to stainless steel internal layer pot and the outer pot of aluminium carries out the frosting technology processing respectively.
C. stainless steel internal layer pot is set in the outer pot of aluminium,, makes the firm metallurgical binding of faying face realization of two kinds of materials make compound pot by mould and forcing press with hot-dip and casting-rolling technology combination.
Compared to prior art, the present invention is owing to adopt " Gu-solid metallic combination process ", and is simpler than traditional metal composite technology, have product qualified rate and productivity ratio height, the characteristics that energy consumption cost is low, through checking, pot has good heat conductivity in this, it is respond well to cook, because internal layer is a stainless steel, does not have the disbonding problem, easy cleaning, acid resistance is good, long service life.
Description of drawings
Fig. 1 is the cross-sectional configuration schematic diagram of inner pan of electric cooker of the present invention;
Fig. 2 is the enlarged drawing at III place among Fig. 1.
The specific embodiment
Elaborate in conjunction with the accompanying drawings with embodiment below:
Fig. 1 to 2 has showed the concrete utilization of the present invention on inner pan of electric cooker, and metal internal layer 1 is the superficial layer that boils among the figure, and this layer stainless steel is because stainless steel has preferable mechanical property and experiences all sorts of durable; Metal outer 2 is to be subjected to thermosphere, and this layer aluminum or aluminum alloy material is because aluminium has preferable heat conductivity.Stainless steel internal layer 1 can not be too thick, otherwise not only processing difficulties also can make pot body heat efficient reduce, and according to optimum principle, the thickness of stainless steel internal layer 1 is 0.1～0.8mm.
Be familiar with the people of technical matters for any one, the kitchen tools of all knowing the multilayer metal compound bottom structure are formed by multiple layer metal roll extrusion when the flat state.And manufacturing process of the present invention is earlier corrosion resistant plate and aluminium to be struck out stainless steel internal layer pot and the outer pot of aluminium respectively, and stainless steel internal layer and the outer field faying face of aluminium handled through frosted respectively, and then stainless steel internal layer pot is set to carries out hot-dip in the outer pot of aluminium and handle again that roll compacting is combined into compound pot, its combination process is to adopt solid-solid metallic complex technique.
The manufacture method step of inner pan of electric cooker of the present invention is as follows:
A. with corrosion resistant plate and aluminium sheet by mould and forcing press respectively punching stretch become stainless steel internal layer pot and the outer pot of aluminium.
B. the faying face to stainless steel internal layer pot and the outer pot of aluminium carries out the frosting technology processing respectively.
C. stainless steel internal layer pot is set in the outer pot of aluminium, adopts hot-dip and rolling casting technology combination, make the faying face realization metallurgical binding of two kinds of materials make compound pot by mould and forcing press.
The foregoing description is only for using the manufacturing of stainless steel-Al bimetal material, also can use this process using as: bimetallic such as stainless steel-copper, iron-aluminium or copper-aluminium or multiple layer metal material manufacture compound pot body or other kitchen tools.
Above step is the unrestricted technical scheme of the present invention in order to explanation only.Any modification or partial replacement that does not break away from spirit and scope of the invention all should be encompassed in the middle of the claim scope of the present invention.
