Making method of cooker, cooker and cooking appliance

Abstract

The embodiment of the invention provides a making method of a cooker, a cooker and a cooking appliance. The making method of the cooker includes the steps that a transitive coating is formed on the inner wall face of a cooker body to be made; an abrasion-resistance oxide coating is formed on the face, away from the cooker body, of the transitive coating; a non-adhesive coating is formed on the face, away from the transitive coating, of the abrasion-resistant oxide coating. In the technical scheme, by arranging the transitive coating, the abrasion-resistant oxide coating is more firmly attachedto the cooker body; by arranging the abrasion-resistant oxide coating, the deformation of the non-adhesive coating under the action of external pressure can be reduced, then the fatigue damage degreeof the non-adhesive coating can be decreased, the service life of the non-adhesive coating is greatly prolonged, then the stability and health of the coatings of the whole cooker can be promoted, andthe problem that coatings are prone to being scratched or stripped off is solved. With the non-adhesive coating, the cooker has non-adhesive performance, and can be a cooker without adhesion, and then the using experience of a user can be improved.

Description

technical field [0001] The invention relates to the field of kitchen utensils, and more specifically, to a preparation method of a pot, a pot and a cooking utensil. Background technique [0002] Most of the non-stick coatings on the surface of the current pots (rice cooker or pressure cooker liner, frying pan, frying pan, etc.) use fluororesin coating, which is mainly to carry out conventional anodic oxidation treatment or sandblasting on the surface of the pot first. Surface strengthening treatment to increase the hardness of the surface of the pot, and then spray a fluororesin coating to achieve the purpose of making the pot non-stick, but the non-stick coating of this structure is due to the anodic oxidation or sanding of the middle part of the bottom The hardness of the layer is reduced and the wear resistance is poor, which leads to a large strain of the non-stick coating under the action of compressive stress, that is, the entire non-stick coating is prone to stress fa...
