Abstract

The utility model provides a dual-layer composite pan which comprises a pan body. The dual-layer composite pan is characterized in that the pan body comprises an internal pan and an external pan that are formed by singly extruding and drawing process; the internal pan is sheathed in the external pan and subsequently punched so as to be connected with the external pan; the internal pan is made by adopting a stainless steel layer; the external pan is made by adopting an aluminium alloy layer; alternatively the internal pan is made by adopting the aluminium alloy layer and the external pan is made by adopting the stainless steel layer; the advantages of the two metal are utilized: the aluminium alloy has good heat conduction, but has low strength and is easy to deform; the stainless steel has good strength but has poor heat conduction; the two metal is compounded so as to prepare the composite pan with good heat conduction performance; furthermore, being different from the pan which is formed by drawing a composite plate, the dual-layer composite pan is formed by separately forming the two pans and subsequently compounding the two pans, therefore, the dual-layer composite pan has low cost, can be heated uniformly and has long service life; simultaneously according to the requirement of a user, the aluminium alloy can be made into the internal pan and the stainless steel can be made into the external pan; furthermore, the surface of the internal pan can be coated with the non-sticking Teflon coating, so that the pan can be used as a non-sticking pan; and the stainless steel can be made into the internal pan and the aluminium alloy can be made into the external pan, so that the dual-layer composite pan is used as an iron pan.

Description

A kind of two-layer compound pot

Technical field

The utility model relates to a kind of cooker, especially a kind of two-layer compound pot.

Background technology

In daily life, the pot of monolayer material, as iron pan, stainless-steel pans etc. are because heat transfer rate is slow, the unequal defective of being heated is progressively to be replaced by the compound pot of multilayer material, common have a dual mode, a kind of is that a pot body is composited by two layers of material, is 98232433.2 as the patent No., a kind of bimetallic compound pot, constitute by hingle and pot body, hingle is fixed on the outside of pot body, it is characterized in that: the pot body is a double metallic composite material, and internal layer is a stainless steel, titanium or iron, skin is a copper, and internal layer and skin are an integral body, though this pot heat-conducting effect is better, it is the composite plate that adopts special construction, sheet material is required than higher, and cost of manufacture is higher; Also having a kind of is to adopt at the bottom of the bottom of a pan of simple material increases one deck compound pot, at the bottom of 200920122139.8 1 kinds of compound pot of the patent No., it includes bottom of pot body and compound bottom sheet, compound bottom sheet covers and is fixed on the bottom of pot body, it is characterized in that bottom of pot body and compound bottom sheet apparent surface form the lines of cooperation respectively, by first hot extrusion cooling means again, compound bottom sheet is compounded on the bottom of pot body by texture structure, it has increased both compound firmness greatly, but adopt the structure at the bottom of the compound pot to increase processing technology, make also inconvenience, and can not adopt stainless pot body, quite big limitation is arranged.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of heat transfer efficiency good at the above-mentioned state of the art, the two-layer compound pot of low cost of manufacture.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of two-layer compound pot, it includes a pot body, it is characterized in that: described pot body is interior pot and the outer pot that adopts independent extrusion stretching moulding, interior pot is enclosed within the outer pot link together through the punching press compacting; Pot is the interior pot of stainless steel layer in described, and outer pot is the outer pot of aluminium alloy layer, and perhaps described interior pot is the interior pot of aluminium alloy layer, and outer pot is the outer pot of stainless steel layer.

As improvement, described interior pot and outer pot disposable bottom stage and mouth lip extruded when extrusion modling, these are different, elegant in appearance with common stretching pot, can substitute compression casting pan.

As improvement, be suppressed with a plurality of air drains in advance on pot and the binding face of outer pot in described, pot be placed in the outer pot in described and be compressed to one by large-tonnage hydraulic press or punch press.

Improve, described air drain is for being the radial symmetrical distribution in the center of circle with center, the bottom of a pan again.

Further improve, when described interior pot is aluminium alloy layer, scribble the not Teflon dope layer of viscosity of one deck, can be used as non-stick pan and use on interior pot surface.

Preferably, the thickness of described stainless steel layer is 0.4～0.5mm, and the thickness of described aluminium alloy layer is 2～5mm.

At last, described interior pot flushes with pot edge, the compound back of outer pot.

Compared with prior art, advantage of the present utility model is: utilize the advantage of two kinds of metals, the aluminium alloy thermal conductivity is good, but intensity is low yielding, and stainless steel intensity is good but poor heat conductivity is made the good compound pot of heat conductivility with two kinds of metal composite; And different with the composite plate drawing and forming pot, after separating moulding, be composited again, cost is low, is heated evenly, and long service life; Simultaneously can be according to user's different needs, be made into the different pot of performance, with aluminium alloy as interior pot, stainless steel is as outer pot, and at the surperficial not teflon coating of viscosity of coating of interior pot, use as non-stick pan, also can be with stainless steel as interior pot, aluminium alloy uses as iron pan as outer pot.
