Abstract
The composite pot with laded bottom has one pot body with bottom in multilayer structure, which includes one heat conducting layer connected to the pot bottom, and one heating layer covering the heat conducting layer. The heating layer consists of one central area and one peripheral area with relatively higher heat conductivity. The present invention has simple structure, homogeneous heating, saving in energy source, wide use in cooking and other features.
Description
Technical field
The invention belongs to a kind of cook utensil, be specifically related to a kind of composite pot with cladded bottom.
Background technology
Existing pot, its structure is mostly fairly simple, all uses homogenous material (stainless steel or aluminium) casting to form.Can only directly heat (as gas burner), and can not directly on the induction thermal source, heat with traditional thermal source.This pot is when heating, and its bottom protective layer is heated soon than inner heat-conducting layer, causes protective layer to separate with heat-conducting layer.For traditional thermal source, the heat that produces towards the thermal source center will be more than the heat that produces towards the thermal source outer peripheral portion.Because it is inhomogeneous to conduct heat, food is burnt at place, pot bottom centre.
The disclosed pot of USA4350259T and CN1558735A, their bottom are that the inductive layer in the middle of clamping by two-layer heat-conducting layer comes the balance heat.But fundamentally still can not solve the problem of bottom centre's position concentration of energy of pot rapidly.
Summary of the invention
The purpose of this invention is to provide a kind of homogeneous heating, composite pot with cladded bottom fast, simple in structure, energy savings conducts heat.
The present invention is achieved in that a kind of composite pot with cladded bottom, comprises a pot body, and the bottom of pot body has hierarchical structure, and the hierarchical structure of bottom comprises the heat-conducting layer that pot bottom connects, and the outer wrap of heat-conducting layer has zone of heating; Zone of heating is made of middle section and outer peripheral areas, and the thermal conductivity of zone of heating outer peripheral areas is higher than the thermal conductivity of zone of heating middle section; And the average conduction between the outer peripheral areas of zone of heating outer peripheral areas and its corresponding pot bottom is higher than the average conduction between the middle section of the middle section of zone of heating and its respective base.
The middle section of described zone of heating can form inductive layer, is made by the material that is applicable to thermal source and the heating of induction thermal source.
Described inductive layer can be made by " 430/304 " stainless iron/steel.
The thickness of described inductive layer can be 0.5～1.5mm.
The outer peripheral areas of described zone of heating can form protective layer, is made by the red copper of high-termal conductivity.
The thickness of described protective layer can be 0.2～1.2mm.
Described pot body can be for circular, oval or square.
A concave surface can be set on the bottom surface of the middle section of described zone of heating.
Can be between described heat-conducting layer, inductive layer and the protective layer by being welded to connect.
The present invention is made of the material layer of three layers of different thermal conductivity.Pot bottom connects the aluminum heat-conducting layer with good heat conductive performance, is used for the heat that branch source of heat release or induction thermal source produce.Heat-conducting layer is heated layer parcel, and zone of heating is made of outer peripheral areas and middle section, the thermal conductivity height of the thermal conductivity ratio central authorities region of outer peripheral areas.During culinary art, the outer peripheral areas of pot bottom is conducted heat fast than the middle section of pot bottom, like this with the heat diffusion at center, the bottom of a pan to the bottom of a pan periphery, the heat around making at the bottom of the whole cooker and the heat uniformity at center prevent that the food of pot bottom center from being burnt.
Description of drawings
Fig. 1 is the hierarchical structure schematic diagram in the bottom of a pan of the present invention;
Fig. 2 is a section diagrammatic sketch of the present invention.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail:
As shown in Figure 1, composite pot with cladded bottom of the present invention, pot body 1 bottom has three aggregated(particle) structures layer by layer.Compared with prior art, it is simple in structure, makes easily.From the bottom surface, be followed successively by middle section 3 and outer peripheral areas 2 from inside to outside.
As shown in Figure 2, composite pot with cladded bottom by down and under structure be followed successively by pot body 1, heat-conducting layer 6, zone of heating.For the pot that homogenous material is made, the bottom of pot body 1 is divided into middle section 5 and outer peripheral areas 4 according to being heated situation with it.Middle section 5 thermal conductivitys are higher by about 1/3 than the thermal conductivity of outer peripheral areas 4.Therefore, can cause the situation that local food burns usually.For fear of the situation of burning foods, connect a heat-conducting layer 6 in the bottom of a pan, and wrap up one deck zone of heating at the external surface peripheral of heat-conducting layer 6.Heat-conducting layer 6 is made by the aluminum with good heat conductive performance, can be used for the heat that the branch source of heat release produces, and makes the heat transfer in the bottom of a pan more even.
Zone of heating is an emphasis of the present invention, and it is effective has solved pot bottom middle section 3 and the uneven problem of outer peripheral areas 2 heating.The middle section 3 of zone of heating is an inductive layer, and outer peripheral areas 2 is a protective layer.Inductive layer 3 is made with the material of protective layer 2 usefulness different thermal conductivity, and the thermal conductivity of promptly claimed layer will be higher than the thermal conductivity of inductive layer.This hierarchical structure, the average conduction between the outer peripheral areas 4 of zone of heating outer peripheral areas 2 and corresponding pot bottom are higher than between the middle section of the middle section 3 of zone of heating and its corresponding bottom 5 average conduction.When heating, heat is more faster than inductive layer at protective layer like this, and thermal source just can be evenly distributed on the whole cooker basal surface by the heat-conducting layer 6 of pot bottom at the too much heat that centre produces, in case the food of stop bit in the pot bottom center is burnt.
Inductive layer makes it both can be applied to traditional heat source (for example gas burner) by having superperformance and corrosion resistant " 430/304 " stainless iron/steel is made, and also can be applied on the induction type thermal source (as electromagnetic oven).
Pot body and heat-conducting layer, inductive layer and protective layer are connected and fixed by the soldering or the Pressure Welding of HTHP, and heat-conducting layer, inductive layer and protective layer are tightly cemented in together.
A concave surface is set on the basal surface of inductive layer, makes the vertically thermal expansion of basal surface of inductive layer like this, protrude and be unlikely to expanded by heating.
In sum, be preferred embodiment of the present invention only, be not the present invention is done any pro forma restriction.The those of ordinary skill of all industry, but all shown in the by specification accompanying drawing and the above, and implement the present invention swimmingly; But all those skilled in the art in not breaking away from the technical solution of the present invention scope, when can utilizing the above technology contents that discloses, and a little change of making, modify the equivalent variations with differentiation, are equivalent embodiment of the present invention; Simultaneously, all essence technology according to the present invention all still belong in the scope of technical scheme of the present invention change, modification and the differentiation etc. of overall any equivalent variations that above embodiment did.
