ABSTRACT:
The present invention relates to a coating layer structure for heat-cookers, and more particularly, to a coating layer structure for heat-cookers wherein said structure has been produced by forming an aluminum oxide (Al2O3) layer on the surface of an aluminum heat-cooker by anodic oxidation and then applying thereon either an anion- and far infrared ray-emitting, inorganic ceramic coating agent or a non-stick, inorganic ceramic coating agent, said both coating agents being non-toxic to human body, and whereby said structure, on heating, does not release any carcinogens and increases heat conductivity at the same time, and said structure also has excellent anti-corrosive and anti-abrasive properties.
