Abstract

The utility model discloses a fume-free iron cooker, the bottom of which is clad with a plurality of layers of materials. The utility model comprises a cooker substrate. At the heating point in the center toward two sides of the bottom of the substrate, a layer of aluminum alloy sheet is clad, on which a cold rolled sheet is clad. With above structure, when the bottom is heated by flame, the heat of the outer cooker body is transmitted through the aluminum alloy sheet in the intermediate layer with excellent heat-conducting performance to the inner cooker body, so the utility model integrates the principle of heat transmission, convection and radiation, hence the heat-conduction coefficient of the cooker is as excellent as that of an aluminum cooker. The utility model is with a rapid heat transmission, conducts heat evenly, with even temperature rise, has no local high temperature; the edible oil cracks at high temperature, which avoids oil fume, so the service life of the cooker is prolonged; in addition, the utility model is of simple and reasonable structure, and easy to use.

Description

The no oil smoke iron pan that the bottom adopts multilayer material to be laminated with

Technical field

The utility model relates to device for cooking, particularly relates to the no oil smoke iron pan that a kind of bottom adopts multilayer material to be laminated with.

Background technology

Iron pan is traditional cooker of China, has irony and directly contacts with food, thereby health is had numerous benefits, and after the carcinogenic incident of U.S. sanitary tissue detection Te Fulong, the iron pan of China is recommended by the World Health Organization to the whole world.The tradition iron pan with cast iron or cold-reduced sheet be base material, cost is low, heat transfer is fast but owing to being heated soon, cause localized hyperthermia, makes the quick cracking of edible oil, oil smoke overflows, and environment and human body are damaged.

In order to solve the oil smoke problem, domestic currently used no oil smoke iron pan all adopts Al-alloy products or stainless steel products, is outer pot in 02266945.0 fume-less cooker adopts as the patent No.

Welding forms folder chamber layer, the patent No. is that 200420017475.3 fume-less cookers are to utilize suction ware tool to solve the oil smoke problem, the patent No. 02136052.9, fume-free stainless steel pan also are to utilize the layer welding of ectonexine pot mouth folder chamber to inject heat medium toward the folder chamber again, reach to be heated evenly.The patent No. 0,226,523 1 quick-heating fume-free pan used in sauteing food, the pot body is an aluminium alloy, forms corrugated with machined in the pot body, spray non-viscous paint in surface utilizes the thickness soaking of aluminum substrate to reach no oil smoke.The no oil smoke of the patent No. 0229731.6 electronic type prompting is to utilize the pot body to be heated to temperature, prompting reaches no oil smoke, these methods are owing to all be to utilize aluminium alloy to conduct heat soon, the thick generation heat distribution of pot body arm does not evenly have oil smoke, but having any can clearly propose their employed explained hereafter means is not the iron pan that compatriots like, and the advantage that has lost iron pan benefit iron is lost traditional theory.

Summary of the invention

The no oil smoke iron pan that the purpose of this utility model is to provide a kind of bottom to adopt multilayer material to be laminated with can not produce oil smoke during the cooking.

The technical scheme that its technical problem that solves the utility model adopts is: comprise the iron pan matrix, be laminated with one deck aluminum alloy sheet in iron pan matrix bottom centre to the heating position of both sides, be laminated with one deck cold-reduced sheet at the aluminum alloy sheet skin again.

The utility model is compared with background technology, the beneficial effect that has is: adopt said structure flame when the cooking that the bottom of outer pan body is heated, the heat of outer pan body is delivered to inner pan body by intermediate layer excellent heat conductivity performance aluminum alloy sheet, make its conduction, convection current, radiation theory of integrating heat, cause thermal conductivity factor to reach the same with aluminum pot good.It is fast to conduct heat, uniform heat conduction, and the pot body evenly heats up, no localized hyperthermia, edible oil does not have Pintsch process and has just avoided oil smoke formation yet, improves the service life of iron pan, also has advantages such as simple and reasonable, easy to use simultaneously.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is an another kind of structural representation of the present utility model.

Among the figure: 1, iron pan matrix, 2, aluminum alloy sheet, 3, cold-reduced sheet.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises iron pan matrix 1, is laminated with one deck aluminum alloy sheet 2 in iron pan matrix 1 bottom centre to the heating position of both sides, is laminated with one deck cold-reduced sheet 3 at aluminum alloy sheet 2 skins again.

Described aluminum alloy sheet 2 thickness are 2～6mm.

Described cold-reduced sheet 3 materials are cold-rolled steel sheet, corrosion resistant plate, stainless iron plate or copper plate; Its thickness is 0.2～1.0mm.

Account for 1/3～2/3 of whole bottom in iron pan matrix 1 bottom centre to the heating position of both sides.

Iron pan bottom be shaped as circle (as shown in Figure 1) or planar shaped (as shown in Figure 2).

The technological process that the utility model is made is:

1, shaping iron pan, machined reach required size and fineness.

2, aluminum alloy sheet drawing, surperficial frosted is handled, and cleans.

3, bottom exterior layer cold-reduced sheet (cold-rolled steel sheet, corrosion resistant plate, stainless iron plate or copper plate) drawing is cleaned.

4, three kinds of different materials: the iron pan matrix, aluminium flake, cold-reduced sheet is laminated with by the high tonnage forcing press integral body of medium-high frequency heating 500～600 degree.Or be laminated with high-frequency heating soldering integral body.

5, polishing, cleaning, packing.

The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
