Abstract

The invention provides cookware , a preparation method thereof and cooking equipment. The cookware comprises a cookware base material; a magnetic conductive coating which is arranged on the outer surface of the cookware base material, wherein the magnetic conductive coating comprises a first magnetic conductive area and a second magnetic conductive area, the second magnetic conductive area is arranged around the first magnetic conductive area, and the first magnetic conductive area is located at the bottom of the cookware base material; the first magnetic conductive area and the second magnetic conductive area meet at least one of the following conditions: the porosity of the first magnetic conductive area is smaller than that of the second magnetic conductive area ; and the surface roughness of the first magnetic conductive area is smaller than that of the second magnetic conductive area. Therefore, when the cookware is matched with the electromagnetic heating coil panel arranged outside the cookware for use, the contact area of the first magnetic conductive area and the temperature sensor is large, the heat transmission efficiency can be effectively improved, and the preparationdifficulty and the preparation cost can be relatively reduced due to the fact that the second magnetic conductive area is relatively large in porosity and / or surface roughness. And a good magnetic conduction heating function of the cookware is still ensured.

Description

technical field [0001] The present invention relates to the technical field of cooking utensils, and in particular, relates to cooking utensils, a preparation method thereof and cooking equipment. Background technique [0002] Aluminum alloy, 304 stainless steel and other materials are widely used in household appliances, but the electromagnetic heating function of these non-magnetic or weakly magnetically permeable pans is not ideal. In order to improve the electromagnetic heating function of the pan, usually A layer of magnetic conduction layer is arranged on the surface, and induction heating is carried out under the eddy current effect formed by the magnetic conduction layer on the outer surface of the pot under the action of a high-frequency alternating magnetic field. However, the magnetic conductive layer is not in close contact with the temperature sensor, which seriously affects the accuracy of the sensor. [0003] Therefore, the cookware for electromagnetic heatin...
