Container and cooking utensil

Abstract

The invention discloses a container and a cooking utensil. The container comprises a container body and a coating, the container body defines a cavity with a top opening, the coating is arranged on the surface of the container body, and the thickness of at least one part of the coating is gradually increased in the radial direction of the container body towards the direction close to the center of the bottom of the container body. According to the container disclosed by the embodiment of the invention, the coating is sprayed on the surface of the container body so that the thickness of the coating is gradually increased along the radial direction of the container body towards the direction close to the center of the bottom of the container body, and therefore, a thermal stress is effectively released, the coating is prevented from falling off, and the reliability of the coating is ensured.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a container and a cooking utensil. Background technique [0002] The inner pot of the existing cooking utensils adopts the electromagnetic heating method, and the inner pot is generally made of iron-aluminum composite board, but the iron-aluminum composite board has the problem of cracking, and the cost is relatively high; or, the inner pot is made of iron-based enamel, and then A non-stick coating is provided on the outside of the enamel layer, but the enamel layer is too brittle, easy to burst, has poor thermal conductivity, and consumes a lot of energy. [0003] In order to solve the above problems, the iron-based pan is sprayed with an aluminum coating on the surface of the iron-based pan to make the pan in the related art. However, due to the difference in thermal expansion coefficient between the aluminum coating and the iron base material, the inner pot will be d...

Problems solved by technology

[0002] The inner pot of the existing cooking utensils adopts the electromagnetic heating method, and the inner pot is generally made of iron-aluminum composite board, but the iron-aluminum composite board has the problem of cracking, and the cost is relatively high; or, the inner pot is made of iron-based enamel, and then A non-stick coating is provided on the outside of the enamel layer, but the enamel layer is too brittle, easy to burst, and has poor thermal conductivity, and consumes a lot of energy

[0003] In order to solve the above problems, the iron-based pan is sprayed with an aluminum coating on the surface of the iron-based pan to make the pan in the related art. However, due to the difference in thermal expansion coefficient between the aluminum coating and the iron base material, the inner pot will be damaged during long-term use. , there is a problem of thermal stress concentration on the aluminum coating and the iron base layer, so that the uniform thickness of the aluminum coating has the problem of partial peeling and rusting during long-term use
