Abstract

The invention relates to an inner container of an electromagnetic heating kettle. An inner container body of the inner container is formed by a composite material of a three-layer structure in a pressure casting manner; a middle layer of the composite material is a conductive magnet layer, rust-proof aluminizing thin layers with the thickness ranging from 20 micrometers to 80 micrometers are attached to the surfaces of the two sides of the conductive magnet layer, and contact between the conductive magnet layer and external air can be prevented through the rust-proof aluminizing thin layers. The top of the composite material for forming the inner container body is outwards rolled to form an edge rolling structure with a square circular bead/ellipse circular bead/ellipse bend cross section; and through the edge rolling structure, the strength of the inner container body can be strengthened, the exposed conductive magnet layer at the top end of the composite material can be wrapped and sealed, and therefore the top end of the conductive magnet layer is isolated from the external air. The edge rolling structure is wrapped and closed with the peripheral edge, so that the top end of the conductive magnet layer is further isolated from the external air. The inner container is large in heating area, the heated face is even, the heating efficiency is high, and the speed is high; and the material cost can be substantially reduced.

Description

Electromagnetic heating pot inner bag

Technical field

The present invention relates to electromagnetic heating pot, be specifically related to a kind of inner bag of electromagnetic heating pot.

Background technology

The inner bag courage body of the electric cooker that market is common generally adopts Heat Conduction Material to make, by by the thermal energy conduction of heating board on inner bag courage body, to reach heating object.The mode that this employing heat exchange pattern carries out heating exists that inner bag courage body heating surface area is little, the thermal efficiency is low, inner bag is easily out of shape the shortcoming such as uneven that causes being heated, and faces the trend be eliminated.Electromagnetic cooker common on the market generally adopts the double layer material die casting be made up of iron and aluminium to form, and its iron layer and aluminum layer thickness are substantially identical, causes its manufacturing cost higher.In addition, no matter be electric cooker inner container or electromagnetic cooker, because the bead structure at courage body top is isolated insufficient to oxidizable, corrosion susceptible materials, service time one is long, and its courage body easily gets rusty, even produces sewage.

Summary of the invention

The invention discloses a kind of Novel electromagnetic heating pot inner bag, be intended to the above-mentioned defect improved existing for existing electric cooker inner container and electromagnetic cooker.

Technical scheme of the present invention is as follows:

A kind of electromagnetic heating pot inner bag, the courage body of this inner bag is made up of a kind of composite die casting of three-decker, the intermediate layer of composite used is magnetic conduction iron layer, the upper and lower surface of magnetic conduction iron layer all with thickness between 20um-80um, the antirust thin layer of aluminizing that can prevent magnetic conduction iron layer and contacting external air.

Further, form the outside turnup in composite top of this inner bag courage body, bead structure that Formation cross-section is square fillet shape, this bead structure more can be wrapped up and be closed the exposed magnetic conduction iron layer in composite top except can strengthening inner bag courage body intensity, thus by the top of magnetic conduction iron layer also with isolate from outer air.

Further, form the outside turnup in composite top of this inner bag courage body, bead structure that Formation cross-section is elliptical fillet shape, this bead structure more can be wrapped up and be closed the exposed magnetic conduction iron layer in composite top except can strengthening inner bag courage body intensity, thus by the top of magnetic conduction iron layer also with isolate from outer air.

Further, form the outside turnup in composite top of this inner bag courage body, bead structure that Formation cross-section is oval bent angle shape, this bead structure more can be wrapped up and be closed the exposed magnetic conduction iron layer in composite top except reinforcement inner bag courage body intensity, thus by the top of magnetic conduction iron layer also with isolate from outer air.

Further, one deck can be set in the periphery of described bead structure and wrap up and the fringing closing this bead structure, thus the top of magnetic conduction iron layer and outside air are completely cut off further.

Material of main part of the present invention is iron plate, and iron plate both side surface is coated with antirust thin aluminium lamination, and compared to electric cooker inner container before, the present invention adopts Electromagnetic Heating mode, and inner bag heating surface area is large, and heating surface is even, and the efficiency of heating surface is high, speed is fast; Because the price of iron is low, and the higher aluminium use amount of price is few, and compared to electromagnetic cooker before, the present invention can reduce the material cost of 30-40% when keeping equal heating effect.In addition, present invention employs multiple oxidizable, the perishable position of isolated inner bag courage body and the bead structure of contacting external air, can effectively prevent inner bag courage body from getting rusty.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Embodiment 1

With reference to Fig. 1, Fig. 2 and Fig. 3:

The bead structure of the present embodiment does not arrange fringing.

A kind of electromagnetic heating pot inner bag, the courage body 1 of this inner bag is made up of a kind of composite die casting of three-decker, the intermediate layer of composite used is magnetic conduction iron layer a, the both side surface of magnetic conduction iron layer a all with thickness between 20um-80um, the antirust thin layer b that aluminizes that can prevent magnetic conduction iron layer and contacting external air.

Form the outside turnup in composite top of this inner bag courage body 1, bead structure 2 that Formation cross-section is square fillet shape, this bead structure 2 can be wrapped up and be closed the exposed magnetic conduction iron layer a in composite top, thus by the top of magnetic conduction iron layer a also with isolate from outer air.

Embodiment 2

With reference to Fig. 4, Fig. 5 and Fig. 6:

The bead structure of the present embodiment does not arrange fringing.
