Problems solved by technology

However, enamel glazes generally contain metal oxide materials such as silica and / or alumina, which have the characteristics of high strength, high temperature resistance, high stability, and high adhesion to metal substrates, resulting in enamel during molding and sintering. The process requires long process time, high sintering temperature, high processing cost, and low yield rate
Moreover, the existing two-time enamel layer preparation method requires two enamel sinterings, so the production line switching time is long during the preparation process, and the appearance defect rate is also high, all of which cause the final cost to remain high.

Embodiment 1

[0043] refer to figure 1 , The pot of the present application includes a pot body 1 and a bottom enamel layer 2 and a surface enamel layer 3 coated on the surface thereof. The pot body 1 is made of metal material. After the bottom glaze slurry is coated on the surface of the pot body 1 and the surface is dry, the bottom glaze slurry layer is formed. Finally, the bottom glaze slurry layer forms the bottom enamel layer 2, and the top glaze slurry forms the top enamel layer 3. Specifically, the surface of the pot body includes at least the inner surface part of the pot body that is in contact with the food when cooking food; preferably, the surface of the pot body includes the entire inner surface of the pot body; more preferably, the surface of the pot body includes the inner surface and the outer surface of the pot body Such as figure 1 shown.

[0044] Those skilled in the art can understand that the metal material of the pot body 1 can be selected from any metal element or ...

Embodiment approach

[0058] As a specific embodiment, a method for preparing a pot includes the following steps:

[0059] 1) After the iron-containing plate is formed into a pot body, the inner and outer surfaces of the pot body are cleaned, rust-proofed, shot blasted and rust-proofed again, wherein the surface roughness Ra of the pot body after shot blasting is 3.5 ~9; re-rust protection provides a new unprotected surface due to shot blasting to prevent rust on the surface of the iron plate. Anti-rust can be treated with silane, phosphating, vitrification, etc.;

[0060] 2) After coating the bottom glaze slurry on the inner surface and outer surface of the pot provided, the surface is dry to form a bottom glaze slurry layer;

[0061] 3) After the bottom glaze slurry layer is wetted with water, the surface glaze slurry is coated on the surface of the bottom glaze slurry layer, surface-dried, trimmed, sintered in a high-temperature sintering furnace and cooled, and the bottom glaze slurry layer for...

Embodiment 2

[0068] This embodiment proposes an electromagnetically heated electric heating pot, which includes a pot body, a pot cover and an electromagnetic heating element, and the pot body includes an outer pot and any pot according to Embodiment 1 placed in the outer pot. The electromagnetic heating element can be an electromagnetic coil or a heating disc. The electric heating pot can be a kitchen appliance that contains ingredients in an inner pot such as an electric rice cooker, an electric pressure cooker, and a cooking machine.

Abstract

The invention discloses a pot and a preparation method and application thereof, and belongs to the technical field of pots. The preparation method of the pot comprises the steps that a pot body made of metal is provided; the surface of the provided pot body is coated with base glaze slurry and then subjected to surface drying, and a base glaze slurry layer is formed; after the base glaze slurry layer is wetted by water, the surface of the base glaze slurry layer is coated with finish glaze slurry and subjected to sintering, the base glaze slurry layer forms a base enamel layer, the finish glaze slurry forms a finish enamel layer, and then, the pot is obtained. According to the preparation method of the pot, two times of sintering in two times of enamel procedures are simplified to one timeof sintering, the water wetting technology is added in the two times of enamel procedures, the production cost is reduced, in addition, it is ensured that the base glaze slurry layer and the finish glaze slurry are mutually dissolved and combined well, the water content difference between the base glaze slurry layer and the finish glaze slurry is reduced, accordingly, the risk that the finish enamel layer formed after sintering is cracked is reduced, and the pot yield is greatly improved.

Description

technical field [0001] The application relates to a pot and its preparation method and application, belonging to the technical field of pots. Background technique [0002] Enamel glaze refers to a thin glass enamel that can be coated on the surface of a metal substrate and sintered. The enamel layer made of enamel glaze has the characteristics of improving the surface of the base material, or it can be used as a means of decoration to beautify and modify the metal substrate. Therefore, the applicability of the enamel layer is relatively wide and multifaceted. [0003] In the field of kitchen appliances, iron inner pots are widely used in cooking utensils such as rice cookers and electric pressure cookers. Compared with inner pots made of aluminum alloy and stainless steel, iron inner pots have better thermal conductivity and heat storage. Uniformity, especially for electromagnetic induction heating products, the iron inner pot can give full play to its unique advantages, th...
