Description
Technical field
The invention belongs to kitchen utensils field, be specifically related to a kind of pan using Electromagnetic Heating.
Background technology
Electromagnetic stove utilizes electromagnetic induction heating, heats and be passed through alternating current in coil during energising, and sensing produces alternating magnetic field,
The magnetic line of force of alternating magnetic field passes through metal pan, produces a large amount of eddy current in the bottom of a pan, thus the heat needed for producing culinary art.Electromagnetic stove
Heating process does not has naked light, therefore safety, health.Ceramic pan is heated evenly, temperature retention time is long, the food nutrition loss of culinary art
Little, it is pan indispensable in life.But the ceramic pan that pot is entirely pottery cannot be used for electromagnetic stove.
Conventional ceramic pot, after one layer of magnetic conductive metal layer is covered in bottom, can heat on electromagnetic kitchen range, substantially increase and cook
The efficiency prepared food.When electromagnetic stove heating power is too high, it is even that ceramic pan there will be temperature distributing disproportionation, such as bottom local temperature mistake
Height, makes food mouthfeel bad；And local heating is easily caused ceramic pan and ruptures, and hurts user, causes security incident.
The problem easily hardening cracked for ceramic pan, currently existing scheme includes: 1, require in the description of product under low-power
Use, it is to avoid ceramic pan temperature quickly raises, temperature distributing disproportionation, causes ceramic pan to rupture, but because at the bottom of power, ceramic pan
Cooking time can become the longest；Rupture it addition, also there will be too high the causing of local temperature when running into dry combustion method.2, select high temperature resistant
Buckpot, at high temperature can will not rupture, but it is relatively costly, and run into dry-fire condition, temperature constantly raises, and time length also can
Appearance ruptures.
Summary of the invention
The problem existed for prior art, the purpose of the present invention is to propose to a kind of temperature automatically controlled electromagnetic stove suitable ceramic
Pot.
It is another object of the present invention to propose the preparation method of described electromagnetic stove suitable ceramic pot.
The concrete technical scheme realizing above-mentioned purpose of the present invention is:
A kind of temperature automatically controlled electromagnetic stove suitable ceramic pot, described electromagnetic stove suitable ceramic pan has sidewall and the bottom of a pan, institute
State sidewall and/or the described the bottom of a pan is provided with temperature control layer；The material of described temperature control layer is curie point at the alloy material of 200～230 DEG C
Material.
The temperature of described curie point includes 200 DEG C and 230 DEG C.
Wherein, described temperature control layer is arranged on outside the ceramic layer in the bottom of a pan.
Or, described temperature control layer constitutes interlayer in being arranged on the ceramic layer in the bottom of a pan.
A preferred technical solution of the present invention is: the material of described temperature control layer is curie point at the alloy of 220～230 DEG C
Material.
For in theory, the lowest being less susceptible to of curie point burns and makes ceramic pan to ftracture, but add time of boiling and
Reduce the mouthfeel of major part food materials, such design, it is possible to realize the economic utilization of firepower to greatest extent.
Another optimal technical scheme of the present invention is: the material of described temperature control layer is curie point at the alloy of 200～220 DEG C
Material.
By such design (scope of low temperature), it is possible to reduce because owing to expanding between alloy material and ceramic material
The inconsistent of coefficient causes coming off of alloy material.
Further, described temperature control layer is that Precise Alloy is made, and the composition of described Precise Alloy is Mn≤0.6%, Si≤
0.3%, 35%≤Ni≤37%, the Fe of surplus.
Preferably, described Precise Alloy is 1J36, the one in 1J38,1J33.
Wherein, the composition of described ceramic layer is Al2O3、SiO2, yittrium oxide, zirconium oxide, Mo Laishi, SiC, Si3N4In one
Plant or multiple.
The thickness of temperature control layer is 0.3～1:3～10 with the ratio of the gross thickness of the wall being provided with this temperature control layer.
Preferably, the gross thickness in the bottom of a pan bigger than the gross thickness of sidewall 1～2mm.The thicker advantage in the bottom of a pan is heat transfer feeding
Thing is more uniform, and temperature control layer generates heat again through thicker ceramic layer, can be heat more Transmit evenly to food.
The bottom of electromagnetic stove suitable ceramic pot can be whole level, it is also possible to outer rim is protruded.Outer rim projection main efficacy results
It is to increase stability and the uniformity of the bottom of a pan heating.Without projection, when the bottom of a pan is stained with foreign material, then can cause the temperature control in the bottom of a pan
Distance between layer and heating coil is inconsistent, thus causes the inequality of being heated in the bottom of a pan, and increases pot when having water in bottom surface
Stablize.
Pan bottom structure can be: the region that the bottom of a pan is provided with temperature control layer is recessed, the bottom of a pan outer rim and the district being provided with temperature control floor
There is the difference in height of 0.1～10mm in territory.Outer rim not can exceed that 10mm with the difference in height in the region being provided with temperature control layer, does not otherwise reach
The effect of heating.
The present invention also proposes the preparation method of described electromagnetic stove suitable ceramic pot, and it is shaped to pot with ceramic powders
Shape, Precise Alloy sheet of fitting in the position in the bottom of a pan, then sinter.
Or, it is shaped to the shape of pot with ceramic powders, imbeds Precise Alloy sheet in the position in the bottom of a pan, then sinter.
The beneficial effects of the present invention is:
The electromagnetic stove suitable ceramic pot of the band temperature control that the present invention proposes, on electromagnetic stove during heating, temperature control layer is by strong
Electromagnetic induction constantly generate heat, and transfer heat to the bottom of a pan and sidewall, along with continuing heating, temperature control layer temperature constantly raises,
Its magnetic conductivity starts to weaken, and i.e. can reduce the actual heating power of electromagnetic stove；When temperature is increased to its Curie temperature, temperature control layer
There will be loss of excitation, on electromagnetic stove, i.e. interrupt heating.The temperature stopping the temperature control layer after heating begins to decline, when temperature is less than it
During Curie temperature, temperature control layer can recover certain magnetic conductivity, makes electromagnetic stove recovery heating, when temperature reaches Curie temperature again
Time, temperature control layer (again can loss of excitation, interrupt heating, the most repeatedly, make the temperature of temperature control layer maintain its near Curie temperature all the time.
Under the regulation and control of temperature control layer Precise Alloy, in cooking process, the temperature of ceramic pan can control, within 230 DEG C, to keep away
Exempt from occur that rupturing occurs in high-temperature embrittlement；The food temperature simultaneously cooked can control within 220 DEG C, it is possible to reduce oil smoke, burning
The generation of the problem such as burnt, to be burned, also improves the effect of culinary art while protection ceramic cooker safety.
