Description

A kind of electromagnetic oven ceramic vessel of built-in heating

Technical field

This utility model belongs to cooking container field, specifically, is related to a kind of pottery with built-in heating for electromagnetic oven Container.

Background technology

Electromagnetic oven also known as electromagnetic stove, are the products of modern kitchen revolution, and it makes heat straight without naked light or conduction-type heating It is connected on the bottom of a pan to produce, therefore the thermal efficiency is greatly improved.It is a kind of energy-efficient kitchen tools, be different from tradition completely all Have fiery or no fiery conduction heating kitchen tools.

Electromagnetic oven is the electric cooking apparatus made using electromagnetic inductive heating principle.It has been broken traditional naked light and has cooked Mode, using the principle of heating of magnetic field induction electric current (being also called vortex), electromagnetic oven is by high-frequency induction heating coil (i.e. excitation wire Circle), RF power conversion equipment, the part such as controller and ferromagnetic material the bottom of a pan cooker form, first pass through electronic circuit board group Become part to produce alternating magnetic field, when placing boiler face with the bottom of pan containing irony, pan cut alternate magnetic force line and in pan Bottom irony part produces the electric current (being vortexed) of alternation, and vortex makes pan iron molecule high speed random motion, and molecule is mutually collided Hit, rub and produce heat energy.

The loop heating coil that can be energized is installed in electromagnetic oven, when loop heating coil leads to and gives electric current, its effect Be equivalent to bar magnet.Therefore there is the generation of magnetic field N-S pole in coil, that is, have magnetic flux to pass through.If the power supply being used is to hand over Stream electricity, the magnetic pole of coil all can produce change with the magnetic flux passing through loop face.It is positioned over loop when there being a magnetic conductive metal face When above coil, now metal covering will faradic current (be vortexed), the more big then produced heat of electric current of sensing is higher, The time boiled needed for food is shorter.Because using magnetic field induction, boiler face does not have electric current to produce, therefore in cooked food When boiler face will not produce high temperature, be a kind of comparatively safe boiling appliance.

Because the thermal source that electromagnetic oven is cooked comes from pan bottom rather than electromagnetic oven heating itself is conducted to pan, The thermal efficiency all exceeds nearly 1 times than the efficiency of all cookers, because electromagnetic oven makes utensil itself voluntarily generate heat at a high speed, for heating And cooking food, thus reach the purpose cooked.There are quick heating, thermal efficiency height, the flames of anger, smoke dust, no harmful gass, right Surrounding does not produce that heat radiation, compact, safety be good and the advantages of appearance looks elegant, and the overwhelming majority that can complete family cooks Prepare food task.

Because electromagnetic oven formed be low frequency (20-25KHZ) coil magnetic field, under the magnetic field of this frequency, aluminum, plastics, The degree that the weak magnetic matter such as pottery is magnetized very little it is impossible to form effective magnetic under low frequency magnetic field effect -- current source road, therefore suitable The irony of kicker magnet or stainless pan can only be used for electromagnetic oven, due to ferrum to the absorption in magnetic field fully, shield effectiveness Also very good, which reduce a lot of magnetic radiations, so the cooker of iron pan material more any than other is also all safer.At present Electromagnetic oven typically can only bake the flat pan of enamel using irony, special rustless steel or ferrum, as pottery, aluminum, copper are material Container or pot then should not be used in electromagnetic oven.

With growth in the living standard, people increasingly focus on the requirement to culinary art, are making the utensil using during food It is also varied, wherein marmite is so that its insulating power is strong, Baoshang stew does not allow the advantages of be easy to run off nutrient substance to be deeply subject to people Like.Under conditions of resource-constrained, most of cooking apparatus are all changed to energising by the mode of coal, natural gas fired heating and add Heat, is heated using electromagnetic oven energising, environmental protection and energy saving, but is had particular/special requirement to the cooking pot being placed on electromagnetic oven.Sand Pot can be also used in and heated on electromagnetic oven, however it is necessary that suitable material and structure.

There now have been the marmite being used in above electromagnetic oven, the mode of whole realization, is all to dig in marmite bottom One groove, rustless steel magnetic conduction sheet is mounted to inside groove, and do so is to reach the effect being used in marmite on electromagnetic oven Really, but can there is certain gap between the rustless steel magnetic conduction sheet inlayed and marmite, even demountable structure, equally easy Food residual in gap, leads to growing of antibacterial.

Utility model content

Technical problem to be solved of the present utility model is to provide one kind not deposit gap, does not result in food residual and leads Cause a kind of ceramic vessel with built-in heating for electromagnetic oven of bacteria breed, in order to ensure the safety and sanitation using ceramic vessel.

This utility model solve above-mentioned technical problem technical scheme be：

A kind of electromagnetic oven ceramic vessel of built-in heating, including vessel 1 and heating layer (2), described heating layer 2 Also include silver layer 21 and magnetic layer 22, described magnetic layer 22 is attached to described vessel 1 bottom interior surface, described silver layer The 21 described magnetic layers 22 of covering are simultaneously attached on described magnetic layer 22 upper surface and described vessel 1 bottom interior surface, isolation The contact with described vessel 1 inner space of described magnetic layer 22.

The thickness of described silver layer (21) and described magnetic layer (22) is than for 15～25: 1.

Preferably, the thickness of described silver layer (21) and described magnetic layer (22) ratio is for 20: 1.

The thickness of described magnetic layer (22) is 0.05～0.15mm.
