Enamel inner container for cooking utensil

Abstract

The invention provides an enamel inner container for a cooking utensil. The enamel inner container comprises a cast iron container body, an enamel glaze layer is sintered on the outer surface of the cast iron container body, a non-stick coating is sprayed to the inner surface of the cast iron container body, an opening of the cast iron container body is provided with an outward radial flange, theenamel glaze layer and the non-stick coating both extend to the flange, corners are formed between the top face of the flange and the outer end face of the flange and between the bottom face of the flange and the outer end face of the flange respectively, and the joint between the enamel glaze layer and the non-stick coating is located at one corner. The inner and outer surfaces of the inner container are provided with the non-stick coating and the enamel glaze layer respectively, and the container has the advantages of having few flaws, and being attractive in appearance and good in touch.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an enamel inner container for cooking utensils. Background technique [0002] Because the iron liner has good heat storage performance, the cooking effect is better than that of other materials, so it is widely used in cooking utensils such as electric rice cookers and electric pressure cookers in the existing market. Among them, the optimal inner tank material is cast iron, but limited by the casting process of cast iron, it is difficult to make the surface of cast iron smooth, so the iron inner tank currently used in the market is formed by stretching thick iron plates to reduce costs . [0003] Most of the coatings for cast iron are enamel, and the rough surface of the enamel glaze layer and cast iron is just conducive to the combination of the two. Cast iron enamel pots are very popular among consumers because of their heavy feeling, beautiful appearance, strong ...

AI Technical Summary

Problems solved by technology

However, most of the existing cast iron enamel pots are integrally sintered enamel, otherwise defects are likely to exist at the end of the enamel glaze layer, and if the gap at the end is obvious, it will also affect the appearance. In addition, the effect of cooking solid food is not ideal due to the poor non-stickiness of the enamel. Therefore, cast iron enamel pots are mostly used as stew pots.

Although the current existing technology misses the cast iron enamel liner, the disclosed content only considers the functional aspects such as internal and external multi-layer angles, and does not involve specific connection issues. There is no real enamel glaze layer in the existing market. Therefore, how to use it as the inner tank of electric rice cooker, electric pressure cooker, etc. remains to be solved
