Embodiment 1

[0044] Referring to Fig. 1 to Fig. 1 of the accompanying drawings of the description of the present invention Figure 4 As shown, a physical non-stick pan with a concave-convex structure according to a preferred implementation of the present invention is illustrated. The types of non-stick pans include cooking pans, frying pans, frying pans, milk pans, etc. In this embodiment, the frying pan For example, its non-stick pan includes a pan body 1, the pan body 1 can be single-layer or multi-layer, when the pan body 1 is a single-layer material can be iron or stainless steel, the alloy elements in the stainless steel are Cr, Ni , Ti, Mn, N, Nb, Mo, Si, Cu and other elements, among which the main alloying element is Cr. For example figure 1 and figure 2 , The pot body 1 is a single layer, including the inner working layer 12. When the pot body 1 is multi-layered, the material can be iron or stainless steel or a composite material, but whether it is single-layer or multi-layer, ...

Embodiment 2

[0049] A method for making a non-stick pan described in Embodiment 1 is described, comprising the steps of:

[0050] (1) Production of the pot body 1: making the pot body 1 from the plate;

[0051] (2) Sandblasting process: choose abrasives, use compressed air as the power, and spray the abrasives on the surface of the pot body 1, so that the surface of the pot body 1 forms a rough surface of at least micron level;

[0052] (3) Surface treatment: harden and oxidize the surface of the pot body 1, and further form an oxide film with a nanoscale rough porous structure on the rough surface.

[0053] (4) Grinding process: perform mechanical grinding on the preset area of ​​the inner surface of the pot body 1, remove the rough surface at the convex edge 111 in the concave-convex structure 11, and retain the rough surface on the concave area 112 in the concave-convex structure 11, and then The pot body 1 of the non-stick pan is obtained; since the top of the ribs is not provided wit...

Abstract

The invention, which belongs to the field of kitchen supplies, relates to a non-stick pan, in particular to a physical non-stick pan with a concave-convex structure and a preparation method thereof. The non-stick pan comprises a pan body and is characterized in that a concave-convex structure is formed on the inner surface of the pan body. The concave-convex structure comprises convex edges protruding out of the inner surface of the pan and a concave area defined by the convex edges, and a physical non-stick layer is at least arranged on the inner surface of the pan body in the concave area. The concave-convex structure is arranged, the convex edges protect the non-stick layer arranged in the concave area, so that direct friction between the pancake turner and the non-stick layer is reduced, and the non-stick effect of the pan body is prolonged.

Description

technical field [0001] The invention belongs to the field of kitchen supplies, and in particular relates to a physical non-stick pan with a concave-convex structure and a preparation method thereof. Background technique [0002] Conventional non-stick pans need to be sprayed with a chemical non-stick coating on the inner surface of the pan. This chemical non-stick coating is easy to decompose and fail at high temperatures, and the coating will be destroyed quickly under the use of a metal shovel. In order to make non-stick pans not easy to stick, easy to clean, and heat evenly and quickly, there are currently many solutions on the market. For example, CN201020591079.7 represents a solution in which a plurality of grooves are arranged on the top surface of the pot bottom to form lines, and a non-stick layer of Teflon material is set in the grooves. There is also CN201310455227.0, which deepens the design of the groove texture setting, defines the length, width, height and bu...
