Description
Technical field
The present invention relates to a kind of electromagnetic stove or electromagnetic oven with modified version conduction marmite and making method, belong to the daily utensil field.
Background technology
Electromagnetic stove more and more obtains the favor of Modern Family because of advantages such as need not naked light, cleaning and pollute, safe and reliable.The ultimate principle of electromagnetic stove is to utilize electromagnetic induction principle, makes pot body produce induced current in high-frequency alternating magnetic field, and induced current forms eddy current, produces heat effect at the pot body, thereby reaches the purpose of heat food.As seen, electromagnetic stove has certain requirement to matching used pot body, and that is exactly that used pot body must produce the electric current eddy current under the effect of alternating magnetic field, and in other words, the bottom surface that pot body itself or pot body contact with electromagnetic stove must have the favorable conductive ability.
Marmite is because acid-alkali-corrosive-resisting, high temperature resistant, freshness, the temperature that can at utmost keep food, and the thing of cooking has peculiar flavour, enjoys liking of people.Yet, for conventional marmite, because it is isolator basically, under the effect of electromagnetic induction, almost can not produce electric current, the hope of using on the electromagnetic stove is very remote.This concerning the electromagnetic stove of not only wishing to utilize safely cleaning, but also wish to enjoy the unique delicious people of marmite food, be a kind of sorry really.
In order to satisfy this class specific demand, two two patent of invention (CN2680156Y of modified version that carry out at conventional marmite have been proposed before the inventor, CN1682627A), enable to satisfy the service requirements of electromagnetic stove, but all there is certain problem in these two kinds of modified version marmites, have limited their widespread uses in daily life.Contain a spot of lead ion in the marmite insulation layer that provides as first patent of invention, harmful to HUMAN HEALTH, according to the provisions of the relevant regulations issued by the State, be can not be as the ceramic cooker that directly contacts with food; And second patent of invention is because the bottom conductive annulus adopts is the mode that the coating electrically conductive slurry then burns electrode at certain high temperature, marmite must experience a high temperature (about about 800 ℃) process again like this, make the conduction marmite because the inequality of being heated ftractures easily, have a strong impact on the yield rate of marmite goods.Therefore must seek environment protection health more electrode materials, take more convenient safe production method for addressing the above problem, the invention provides a kind of follow-on conduction marmite and preparation method thereof, be expected to electromagnetic stove supporting widely-used.
Summary of the invention
