Porcelain pot for electromagnetic range and production method thereof

Abstract

The invention discloses a porcelain pot for an electromagnetic range and a production method thereof. The porcelain pot for the electromagnetic range comprises a pot body which is a lithium and cordierite compound porcelain pot body produced by combining lithium and cordierite ceramic; and a ferrous film layer is arranged at the bottom of an inner surface of the pot body. The production method of the porcelain pot for the electromagnetic range comprises the steps of firing the lithium and cordierite compound porcelain pot body, coating a film containing a ferrous element at the bottom of the inner surface of the pot body, firing under protective gas and finally obtaining the porcelain pot containing the ferrous film layer for the electromagnetic range. The ferrous film layer is coated at the bottom of the inner surface of the porcelain pot, so that the porcelain pot with the ferrous film layer can generate an electric magnetic field when applied to the electromagnetic range; the heat generated by the ferrous film layer under the action of the electromagnetic field is directly used for heating food, so that the ferrous film layer has the advantages of high heating speed and energy source saving; and the porcelain pot body can also effectively avoid the dissipation of the heat. The production method has the advantages of simple process, convenient operation, strong controllability and the like and is beneficial to being popularized and applied.

Description

technical field [0001] The invention relates to a cooking utensil and a manufacturing method thereof, in particular to a ceramic pot for an electromagnetic cooking range that can generate an electromagnetic field when used on an electromagnetic cooking range and directly heat food through the heat generated by the electromagnetic field and a manufacturing method thereof. Background technique [0002] At present, metal pan is a kind of cooking utensil generally used in daily life. In the cooking process, the common heating method is to use a heat source to heat the bottom of the pot. After the bottom of the pot is heated, the heat is transferred to the pot body. The pot body is in a passive heating state, and the heat energy generated by the heat source radiates outward in a large amount during the transfer process. , convection and conduction, resulting in a large waste of energy. Since the heat is mainly transferred by conduction, the heating rate of the pot body is slow. ...

AI Technical Summary

Problems solved by technology

However, if you use frying, frying, deep-frying and other heating methods with high temperature, rapid fire, and large temperature difference, it is easy to burst

Although some research institutes have developed certain special ceramics, which have the advantages of high temperature resistance and no bursting in case of emergency fire, but the cost of raw materials and process requirements are relatively high, and the manufacturing method is very complicated, which is not conducive to popularization and use.

[0004] It can be seen that with the improvement of living standards and the acceleration of the pace of life, the existing cooking utensils have been unable to meet the growing needs of people.
