A kind of electromagnetic induction ceramic cooker
Technical field
The utility model relates to a kind of ceramic cooker that cooking food is used that is used for, and especially designs a kind of electromagnetic induction principle that utilizes, and can be used for the ceramic cooker of electromagnetism heating.
Background technology
The cooker that is applicable to the electromagnetism heating can only be made with metal material at present, this is determined by the electromagnetism heating principle: when the coil of electric current by electromagnetic oven produces magnetic field, when metal material that the magnetic line of force in magnetic field is surveyed in by cooker, produce countless little eddy current, make cooker heating itself, the food in the cooker is heated.And the cooker of general ceramic material can not directly carry out the electromagnetism heating, because magnetic field is to not influence of pottery.
At present, the mode of the electromagnetism zone of heating of the cooker that is applicable to electromagnetic oven that has by thermal spraying is attached to the surface of pottery, and the electromagnetism zone of heating of the cooker that is applicable to electromagnetic oven that has is arranged on the exterior bottom of cooker.For example Granted publication number is the utility model " but pan of a kind of electromagnetism heating " of CN2910034Y, and and for example Granted publication number is the utility model " electromagnetic oven heat-stable ceramic pot " of CN2738690Y.In use, because pottery is different with the thermal conductivity factor of electromagnetism zone of heating, and cause the electromagnetism zone of heating to come off.Because pottery is the non-conductor of heat, therefore give the heat transfer of food slower, and cooker bottom thermal-arrest is serious, has influenced the service life of electromagnetic oven again.
Summary of the invention
The utility model purpose is: a kind of electromagnetic induction ceramic cooker that can use on the heater that utilizes electromagnetic induction principle work is provided, such as using, and has characteristics such as heat conduction is fast, good heat insulating, long service life on electromagnetic oven.
The technical solution of the utility model is: a kind of electromagnetic induction ceramic cooker, comprise the cooker body, also comprise the graininess alloying metal layer that is positioned at described cooker body inboard and is close to the cooker inner body wall, and covering glaze layer on the graininess alloying metal layer, the thickness of described graininess alloying metal layer is between 0.1mm~0.5mm.
Further, the thickness of the graininess alloying metal layer of described electromagnetic induction ceramic cooker is 0.1mm.
Further, the thickness of the glaze layer of described electromagnetic induction ceramic cooker is between 0.1mm~0.5mm.
Further, the graininess alloying metal layer of described electromagnetic induction ceramic cooker covers the inwall of whole cooker body.
Perhaps, further, described graininess alloying metal layer is round pie, is positioned at the bottom of the inwall of cooker body.
The utility model has the advantages that: the original conventional culinary characteristics that kept pottery, kept good heat build-up and the heat-insulating property of conventional ceramic cooker, kept ceramic sanitation and hygiene, depositing food can be not contaminated, saves energy and the advantage of time again, can on electromagnetic oven, use again simultaneously, simultaneously can also be as pot in the storing of electric cooker and slow cooker, the crowd who is fit to all ages and classes level and different occupation uses.The pottery pot of the utility model and other electromagnetic oven special use is compared, and heat conduction is faster.In addition, the alloying metal layer is made by sintering process, even therefore cooker dry combustion method alloying metal layer of the present utility model can not come off yet.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the profile of the electromagnetic induction ceramic cooker of present embodiment 1;
Fig. 2 is the profile of the electromagnetic induction ceramic cooker of present embodiment 2.
Wherein: 1 cooker body; 2 graininess alloying metal layers; 3 glaze layers.
The specific embodiment
Embodiment: the electromagnetic induction ceramic cooker of present embodiment comprises cooker body 1, alloying metal layer 2 and glaze layer 3 as shown in Figure 1.
Described electromagnetic induction ceramic cooker body 1 can be pottery pot, ceramic pot, ceramic teapot, ceramic Chinese medicine kettle pottery barbecue dish, ceramic deep fryer etc.This electromagnetic induction ceramic cooker only requires the bottom shape of cooker body and utilizes the heater surfaces of electromagnetic induction principle work to fit, and does not have other requirements in shape.Generally speaking, the bottom of electromagnetic induction ceramic cooker body 1 is flat.
Graininess alloying metal layer 2 is positioned at the inboard of cooker body 1, and is close to the inwall of cooker body 1, and general, cooker body 1 is a ceramic material.Graininess alloying metal layer 2 covers the ceramic inner surface of cooker body 1 by sintering process.As shown in Figure 1, the graininess alloying metal layer 2 of embodiment 1 is round pie, is positioned at the inwall bottom of cooker body.As shown in Figure 2, the graininess alloying metal layer 2 of embodiment 2 covers the inwall of whole cooker body.Graininess alloying metal layer 2 can adopt one or more metal materials in nickel, iron, the silver to make, and is preferred, adopts the silvery gold metal layer of making a match, and thermal conductivity is better.The thickness of alloying metal layer 2 is between 0.1mm~0.5mm, and the thickness of preferred alloying metal layer 2 is 0.1mm.
Glaze layer 3 covers the outside of graininess alloying metal layer 2, make food can not with touch the alloying metal layer, protection graininess alloying metal layer 2 is not worn, and prolongs the service life of electromagnetic induction ceramic cooker simultaneously.Glaze layer 3 adopts earth silicon material to make stable performance, high temperature resistant, corrosion-resistant, wear-resistant.The thickness of glaze layer 3 is between 0.1mm~0.5mm.
Also be furnished with the safety glass lid on the electromagnetic induction ceramic cooker in addition, or the lid of other materials, the use of electromagnetic induction ceramic cooker do not influenced.
The above only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, and all simple conversion of doing according to the utility model claim and description all should still belong to protection domain of the present utility model.
