Improved type conductive marmite and manufacturing method thereof

Abstract

The invention relates to an improved type conductive marmite and a manufacturing method thereof. The improved type conductive marmite is characterized by sequentially comprising a marmite body ceramic, a glaze and a conductive metal aluminum layer, wherein the conductive metal aluminum layer is positioned at an outer bottom; the marmite body ceramic (1) comprises the following components in percentage by weight: 20%-27% of Suzhou No.1 clay, 12%-17% of camwood knots, 3%-8% of Zhangzhou clay, 35%-43% of spodumene and the balance of Gangxi talcum; the glaze (2) comprises the following components in percentage by weight: 25%-35% of the spodumene, 30%-45% of magnesium oxide, 6%-12% of zinc oxide, 3%-7% of Suzhou No.1 clay, 5%-8% of tin oxide,, 8%-15% of silicon micropowder and the balance of self-made fusion cakes; and the conductive metal aluminum layer (4) is completely covered at the bottom of a marmite body. The manufacturing method comprises the following steps of: weighing materials according to the formula of the marmite body ceramic; and stirring, mixing, adding water, vacuumizing, forming, drying, glazing, and finally burning. The improved type conductive marmite disclosed by the invention is possible to be hopeful in large-scale application on an electromagnetic cooker and has a good market prospect.

Description

technical field [0001] The invention relates to an electromagnetic cooker or an improved conductive casserole for an electromagnetic cooker and a production method thereof, belonging to the field of daily-use utensils. Background technique [0002] Induction cooker is more and more favored by modern families because of its advantages of no open flame, clean pollution, safety and reliability. The basic principle of the induction cooker is to use the principle of electromagnetic induction to make the pot body generate an induced current in a high-frequency alternating magnetic field, and the induced current forms an eddy current, which produces a thermal effect on the pot body, thereby achieving the purpose of heating food. It can be seen that the electromagnetic cooker has certain requirements for the pot body used in conjunction with it, that is, the pot body used must be able to generate current eddy currents under the action of an alternating magnetic field.

Problems solved by technology

[0004] In order to meet such special needs, the inventor proposed two improved two-piece invention patents (CN2680156Y, CN1682627A) for conventional casserole, so that it can meet the requirements of electromagnetic cooker, but these two improved casserole are both There are certain problems that limit their wide application in daily life

For example, the insulating layer of the casserole provided by the first invention patent contains a small amount of lead ions, which is harmful to human health. According to the relevant national regulations, it cannot be used as a ceramic cooker that is in direct contact with food; The ring adopts the method of coating the conductive paste and then firing the electrodes at a certain high temperature, so that the casserole must go through a high temperature (about 800°C) process again, which will easily cause the conductive casserole to crack due to uneven heating, which will seriously affect the finished product of the casserole product.
