Embodiment 1

[0073] The cooking container of the present application can be any container that can process food, such as a pot, the cup body of a cooking machine or a cooking machine, etc., wherein the pot includes not only a frying pan, an inner pot in an electric rice cooker, etc., it is especially suitable for Frying pan, take the wok utensil of frying pan as an example in the following embodiments for illustration.

[0074] refer to figure 1 , as an embodiment, the manufacturing method of cooking container comprises the following steps:

[0075] shaping the cooker base material into a cooker base body 1;

[0076] Carry out sandblasting roughening to the inner surface of cooking container base body 1;

[0077] Provide molten injection raw materials for alloy compositions;

[0078] Spraying the raw materials to the inner surface of the cooking container base 1 to form a spraying layer 2, that is, to make a cooking container;

[0079] Wherein, the material injection outlet of the spra...

Embodiment 2

[0083] refer to figure 2 , when the spray outlet is located at the base point where the central axis of the cooking vessel coincides, the distance between the spray outlet and the inner surface of the cooking vessel is L1; The surface distance is L3, and when the spray outlet swings between the base point and the limit position, the distance between the spray outlet and the inner surface of the cooking container is L2, and L1<L3<L2. The way of changing the distance between the spray outlet and the cooking container can make the center of the bottom of the cooking container, such as the bottom of the pot, have the highest hardness and the lowest porosity, and the hardness of the top edge of the cooking container, such as the opening of the pot, is second. The porosity increases, while the transition between the bottom and top openings is the least rigid and most porous. In actual use, for example, the loss of the bottom of the pot is the largest, followed by the opening of th...

Embodiment 3

[0094] This embodiment provides a cooking utensil, which is described by taking a pot as an example.

[0095] As an embodiment, the pot includes a pot base, the inner surface of the pot base is attached with a spray layer formed by a melt spraying process, and the spray layer is an iron alloy; the cooking container has a main cooking area and an auxiliary cooking area surrounding the main cooking area. Cooking area; on the main cooking area, the thickness of the spray layer is 0.2 mm to 2 mm; the thickness ratio of the auxiliary cooking area to the main cooking area is 0.25 to 0.9. Under the same heat source, the heating temperature near the center of the pot is higher than that at the edge. By setting the thickness of the main cooking area near the center of the pot to be greater than the thickness of the auxiliary cooking area at the edge, the heating rate of the center of the pot is close to that of the edge. Reduce the temperature difference between the center and the edge...

Abstract

The application discloses a cooking container and a manufacturing method thereof, belonging to the field of kitchen utensils. The manufacturing method of the cooking container comprises: forming the base material of the cooking container into a base body of the cooking container; sandblasting and roughening the inner surface of the base of the cooking container; providing a fusion injection raw material of the alloy composition; A spray layer is formed on the inner surface of the substrate to obtain a cooking container; wherein the spray outlet of the spray gun used for spraying is set opposite to the opening of the cook container, and the spray outlet swings to the edge of the cook container with the central axis of the cook container as the base point. The container rotates around its central axis, and the sprayed layer is formed by multi-layer thermal spray coating of the molten sprayed raw material of the alloy composition covering the inner surface of the base of the cooking container. The thickness distribution mode of the sprayed layer prepared by the cooking container manufacturing method is beneficial to the cooking surface of the cooking container to heat more evenly, and the sprayed layer formed by spraying has high bonding strength, high hardness, low porosity and low residual tensile stress.

Description

technical field [0001] The application relates to a cooking vessel and a manufacturing method thereof, which belong to the field of kitchen utensils. Background technique [0002] The cooking surfaces of existing cooking containers are prone to corrosion, peeling off of the anti-corrosion layer and scratches. Especially when using traditional cast iron, stainless steel, aluminum, aluminum alloy and other metal pans to cook food, corrosion and scratches are prone to occur, which reduces the service life of metal pans. [0003] Existing cooking containers mostly use the mode of coating non-stick layer to solve the anti-corrosion problem. For example, the existing pots solve the anti-corrosion problem by coating a layer of organic polymer such as polytetrafluoroethylene anti-stick coating on the inner surface of the pot, and anti-corrosion utilizes the anti-acidity of polytetrafluoroethylene. However, the polytetrafluoroethylene anti-stick coating has the following problems: ...
