Problems solved by technology

[0002] In the past, electromagnetic heating appliances, such as IH rice cookers or induction cookers, were generally made of iron or iron-aluminum composite boards as heating appliances. However, due to the poor thermal conductivity and high thermal inertia of iron materials, the effect of rapid heating cannot be achieved. Energy efficiency is not high
However, pots using carbon-based composite materials cannot be directly used as pots because of the porous material structure of carbon-based composite materials, strong adsorption, fragile materials, and single surface appearance.

Description

technical field [0001] The invention belongs to the technical field of kitchen cooking appliances, and in particular relates to a composite-coated cookware, a surface treatment method for the cookware, and an electromagnetic heating appliance. Background technique [0002] In the past, electromagnetic heating appliances, such as IH rice cookers or induction cookers, were generally made of iron or iron-aluminum composite plates as heating appliances. However, due to the poor thermal conductivity and high thermal inertia of iron, the effect of rapid heating cannot be achieved. The energy efficiency value is not high. The cookware using carbon-based composite materials cannot be directly used as cookware due to the porous material structure of carbon-based composite materials, strong adsorption, fragile materials, and single surface appearance. [0003] Therefore, based on these problems, there is provided a composite coating cookware and a surface treatment method for the coo...
