Description

A kind of composite pan

Technical field

The utility model relates to pan field, specifically a kind of pan be made up of composite.

Background technology

Current pan has iron pan, aluminum pot and stainless-steel pan, and iron pan is with health role to human body, but its poor heat conductivity, heaviness, oxidizable hymeniderm, rapid wear easily becomes rusty, and service time is short.Aluminum pot is light and handy, and heat conduction is fast, but aluminum pot poor thermal insulation property, and and Long-Time Service is known from experience people and is caused slow poisoning and iron deficiency, and the disease relevant with brain, the heart, Liver and kidney function finally can be caused to occur.Stainless-steel pan is attractive in appearance beautiful, durable in use, but its poor thermal conductivity, and during use, pot body each position food is heated inequality, easily produces sticky pot and to be burned phenomenon, and energy-and time-economizing weak effect.

The pot that more existing metallic composites are made, as the composite material cooking vessel of stainless steel (or iron)-aluminium (or copper)-stainless steel (or iron), the aluminium (or copper) in its intermediate layer has good malleability, but heat conductivility is limited, and for ensureing that intermediate layer reliably can be connected with the metal material of other layer, have certain requirement (generally more than 1 millimeter) to the thickness in intermediate layer; In addition, the processing in intermediate layer first tabular aluminium (or copper) is cut into the sheet material with suitable shape, then be shaped with mould punching, high pressure compound is adopted to make composite plate in intermediate layer and other metal level again, last blanking punched one-tenth disk, the techniques such as shaping, drawing, spinning make metallic composite pot, and the processing technology of above-mentioned pan is complicated, cost is high, the metal material wasting of resources.

Utility model content

Technical problem to be solved in the utility model is the defect overcoming the existence of above-mentioned prior art, provides a kind of heat-transfer rate fast and the composite pan of good heat insulating.

For this reason, the technical solution adopted in the utility model is as follows: a kind of composite pan, comprise inner pan body and outer pan body, it is characterized in that, be provided with at least one deck between described inner pan body and outer pan body and be close to the carbon membrane on inner pan body outer wall, be provided with at least one circle between the lateral wall of inner pan body and the madial wall of outer pan body or one deck has flexible insulator, described insulator is partly or entirely fixed between outer pan body madial wall and carbon membrane outer surface; The top edge of described inner pan body is connected with the top edge of outer pan body.

Carbon membrane is formed through high temperature pyrolysis charing by carbonaceous material as a kind of inoranic membrane of novelty, and it not only has good heat transfer property and higher resistance to elevated temperatures, higher mechanical strength, but also it is thin, lightweight to have thickness.Insulator has good heat insulation, heat-insulating property, and has certain elasticity.Insulator also plays a role to the fixing of carbon membrane.The thermal conductivity factor of carbon membrane is greater than 500w/mk, and some can up to 1900w/mk, and the thermal conductivity factor of heat conductivility best metal copper can only reach about 400w/mk at present.The heat conductivility of carbon membrane is several times of copper even decades of times.

As improving further and supplementing technique scheme, the utility model takes following technical measures:

The exterior bottom wall of described inner pan body is all covered by carbon membrane, and the lateral wall of inner pan body is all or part of to be covered by carbon membrane.The exterior bottom wall of inner pan body requires high to heat-transfer rate, therefore all covers with carbon membrane, so also energy-conservation.The lateral wall of inner pan body all or part carbon membrane covers, and determines according to the actual demand of pan sidewall heat.

The carbon membrane of inner pan body lateral wall covers the two kinds of distribution forms adopted below: 1) lateral wall of described inner pan body is covered by many strip carbon membrane parts, gap is there is between adjacent strip carbon membrane, many described strip carbon membranes longitudinally arrange and are that circumference is uniform, the lower end of strip carbon membrane is connected as a single entity with the toroidal carbon membrane being positioned at inner pan body exterior bottom wall, and the upper end of strip carbon membrane is connected by a circle carbon membrane bar.2) lateral wall of described inner pan body is covered by polylith petal-shaped carbon membrane, described polylith petal-shaped carbon membrane surrounds an annular closed, polylith petal-shaped carbon membrane after expansion is uniform in circumference, and the lower end of petal-shaped carbon membrane is connected as a single entity with the toroidal carbon membrane being positioned at inner pan body exterior bottom wall.The carbon membrane consumption of the first distribution form is few, and the carbon membrane consumption of the second distribution form is large, and heat-conducting effect, the second distribution form is better than the first distribution form.Why the carbon membrane of the utility model inner pan body lateral wall adopts above-mentioned two kinds of distribution forms, is the stickup facilitating carbon membrane and inner pan body, avoids wrinkle occur.If the carbon membrane of inner pan body lateral wall adopts a continuous print annular element, then wrinkle can be there are and waste of material is serious.

The material of described insulator is silica gel or litaflex, meets that the utility model is heat insulation to insulator, the requirement of heat-insulating property, can certainly adopt other similar material.

The upper surface of described insulator flushes higher than the carbon membrane upper surface on inner pan body lateral wall or with the carbon membrane upper surface on inner pan body lateral wall.This structure makes insulator upper surface with the pan non-scald on hand of upper part, user-friendly pan.

The diapire of described outer pan body is formed the outer recessed upper salient point of multiple convex, the diapire of inner pan body is formed the outer recessed lower salient point of multiple convex, upper salient point and lower salient point with the use of, the carbon membrane area that overlays in inner pan body exterior bottom wall can be made so larger, and also make carbon membrane and inner pan body fit tightr.

The thickness of described carbon membrane is less than 0.5 millimeter, and its inner surface scribbles adhesive, utilizes adhesive to make the connection of carbon membrane and inner pan body more reliable.

The material of described inner pan body is iron, aluminium, stainless steel, stainless iron, aluminium alloy or pottery, and the material of described outer pan body is iron, aluminium, stainless steel, stainless iron or aluminium alloy.Select corresponding material according to actual needs, due to good heat conduction effect of the present utility model, therefore make the material of inner pan body adopt pottery.

The beneficial effect that the utility model has is as follows: carbon membrane is applied on pot as a kind of excellent conduction material by the utility model, significantly improves the heat conductivility of pan; Because carbon membrane layer is thin, lightweight, make the lower thickness of overall pan, save metal material consumption.Carbon membrane layer of the present utility model and thermal insulation layer is easy to process, processing technology is simple, the processing technology of whole pot is also simple, convenient.
