Description

Dual-layer composite pan

Technical field

The utility model belongs to cooker field, especially relates to a kind of Dual-layer composite pan.

Background technology

Pan is on the market generally iron pot, aluminium matter pot or stainless-steel pan, the function of non-stick pan can be realized at aluminium matter pan inner surface spraying antistick layer, but antistick layer meets high temperature can decompose generation harmful substance, unfavorable to health, be not suitable for the cooking method that Chinese tradition likes quick-fried, and antistick layer easily comes off after a long time use, shorten the service life of pot; And the pan of irony gets rusty easily after using for a long time, and the oil smoke produced during culinary art is larger; Although stainless-steel pan solves magnetic conduction and antirust problem, its local heat-transfer rate too fast, cause pot entirety to be heated uneven, and spraying realize non-stick pan function after service life shorter.

Through improving, have developed the compound pot with the multiple end, pot embryo and multiple bear building-up are combined by the welding procedures such as general employing soldering, as Chinese patent CN202457811 discloses one " two-layer compound composite bottom boiler ", its pot of body comprises pot body matrix and the pot body multiple end, and the pot body multiple end comprises heat conduction interlayer and stainless steel double egative film, and pot body matrix is the matrix of double-level-metal one composite molding, wherein internal layer is stainless steel layer, and skin is aluminium alloy layer.This two-layer compound composite bottom boiler have heat transfer rate fast, be heated evenly, healthy, can the direct-fired advantage of use electromagnetic oven.But because internal layer is stainless steel layer, this design realizes the function of non-stick pan after cannot spraying, and consumer finds in actual use, because heat conduction interlayer does not fully extend, be out of shape less, pot body matrix and the pot body multiple end firm in conjunction with defective tightness, long-time use after the pot body multiple end easily come off from pot body matrix, service life is shorter.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provide a kind of be suitable for spraying become non-stick pan and the Dual-layer composite pan be heated evenly.

The utility model solves the technical scheme that its technical problem adopts: a kind of Dual-layer composite pan, comprise pot body and the bottom of a pan, described pot body comprises aluminum alloy inner layer and stainless steel is outer, and the described the bottom of a pan comprises transition zone and multiple bottom, and described pot body is connected by hot strike-on mode with the bottom of a pan.Pot body comprises aluminum alloy inner layer, thus can spray non-adhesive coating at inner surface of pot body, and use as non-stick pan, stainless steel skin makes homogeneous heating, not easily oxidized.And hot strike-on connects the conjugation that improve pot between body and the bottom of a pan, make it connect more closely firm, and heat conductivility is better, heat conduction efficiency is high, be heated evenly.

As preferably, described transition zone is aluminium lamination, aluminium alloy layer, layers of copper or zinc layers.The connection of pot body and multiple bottom is convenient in the setting of transition zone.

As preferably, described transition zone is made up of 1050 pure aluminum materials.Fully can extend, produce larger deformation, thus increase conjugation and the compactness of pot body and multiple bottom.

As preferably, described multiple bottom is stainless steel layer.Achieve the function of magnetic conduction, make it directly use on electromagnetic oven.

As preferably, described multiple bottom is made up of 430 stainless steel materials or 410 stainless steel materials.

As preferably, the thickness of described aluminum alloy inner layer is 1.0-5.0mm.Not only can spray non-adhesive coating, and can arrange texture as required, pot body is heated more even.

As preferably, the outer field thickness of described stainless steel is 0.4-0.8mm.This stainless steel skin accelerates heat transfer rate.

As preferably, the thickness of described transition zone is 1.5-6.0mm.Transition zone adds the thickness in the bottom of a pan, make to be heated evenly, avoid producing too much oil smoke, energy-conserving and environment-protective more, and the design of this thickness makes transition zone in hot strike-on process fully to extend to merge coated with bottom of pot body, and then increase the conjugation of answering bottom and pot body.

As preferably, the thickness of described multiple bottom is 0.3-0.8mm.[jh1]

The beneficial effects of the utility model are, structure is simple, can become non-stick pan in inner surface of pot body spraying, directly can use on electromagnetic oven, and be heated evenly, not easily produce oil smoke, pot body and the bottom of a pan conjugation high, good heat conductivity, substantially prolongs the service life of pot.

Detailed description of the invention

The utility model scheme is better understood in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.

With reference to shown in Fig. 1, Fig. 2, a kind of Dual-layer composite pan, comprises pot body 1 and the bottom of a pan 2 being located at pot body 1 bottom outer surface.Pot body 1 is made up of two-layer compound sheet material, and it comprises aluminum alloy inner layer 13 and stainless steel skin 14, and in the present embodiment, aluminium alloy layer is the aluminum alloy material of 3003, and stainless steel layer is the stainless steel of 304 or 430.During manufacture, be aluminium alloy skin by internal layer be stainless composite board one drawing and forming, and stay larger skirt as reinforcement at the flanging place of pot body 1, be convenient to following process, prevent the high temperature of subsequent process from causing pot body 1 to be out of shape, until carry out trimming process again after completing the operation needing high-temperature process, make target shape pot body 1.Wherein the thickness of aluminum alloy inner layer 13 is 1.0-5.0mm, and the thickness of stainless steel skin 14 is 0.4-0.8mm.
