Problems solved by technology

[0002] In recent years, because electromagnetic heating can solve the problem that the heating plate is difficult to achieve three-dimensional heating, more and more cooking utensils such as rice cookers, pressure cookers, and induction cookers use electromagnetic heating, but only ferromagnetic metals are used as cooking utensils. Electromagnetic heating can only be realized, so most of the pots are made of stainless steel or stainless steel and aluminum composite materials, and the cost of this material is relatively high
However, there are two problems with the use of iron pans: 1. Iron is easy to rust; 2. The pretreatment process of spraying non-stick coating on the inner surface of the pan adopts phosphating or blackening process, which pollutes a lot and affects the environment

Abstract

The invention provides a cooker, a cooking utensil assembly and a manufacture method of the cooker. The cooker comprises an iron base body, a first aluminum oxide layer and a non-stick coating. The non-stick coating is attached to the inner wall surface of the iron base body. The non-stick coating is sprayed on a layer surface of the first aluminum oxide layer. Advantages of aluminum oxide such asgreat hardness, compact structure, wear resistance and corrosion resistance are made full use of because the inner wall surface of the iron base body is equipped with the first aluminum oxide layer as an interlayer. Therefore, bonding force between the non-stick coating and the iron base body is improved. The non-stick coating is more firmly attached to the iron base body and used for longer service lifetime. Pollution to the environment is avoided due to phosphorization or oxide treatment by avoiding the defect in the prior art that phosphorization or oxide treatment is needed by the inner wall surface of the iron base body prior to spraying of the non-stick coating.
