Description

Technical Field

[0001] The invention relates to the technical field of cookware, in particular to a non-stick pan. Background Art

[0002] Currently, non-stick pans on the market are generally made of single-layer steel or composite steel. In order to achieve the non-stick effect, polytetrafluoroethylene (PTFE) is generally sprayed directly inside the pan body. However, in daily life, when the heating flame is too strong, the heating of the pan body is prone to unevenness, which causes the polytetrafluoroethylene (PTFE) in the center of the pan body to sinter. As a result, a non-stick pan with a concave-convex structure on the inner and outer surfaces of the pan body appears on the market, and a non-stick coating is provided on the concave parts of the concave-convex structure. This design effectively prevents direct contact between food and the inner surface of the pan body and effectively improves the anti-stick effect of the non-stick coating. However, the product is still not resistant to high-temperature fire and cannot meet the actual use requirements of the pan. Summary of the invention

[0005] A high heat-resistant non-stick pan according to an embodiment of the present invention has at least the following beneficial effects: since the bottom of the pan body is compounded with a heat-conducting sheet and a steel plate, the overall heat-conducting performance of the pan body is better, and the non-stick pan coating is prevented from sintering.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] Reference Figure 1 A high heat-resistant non-stick pan comprises a pan body 1, which can be made of single-layer steel or composite steel, and the thickness of the pan body 1 is 0.5-5 mm; the inner surface of the pan body 1 is coated with a non-stick coating, and in order to achieve a better anti-stick effect, the inner surface of the pan body 1 can be provided with a first concave-convex pattern 11, and in order to achieve a better decorative effect, the first concave-convex pattern 11 is a polygonal pattern with a uniform matrix distribution, and of course it can also be an irregular pattern.

[0025] Reference Figure 2 , Figure 3 The bottom of the pot body 1 of this embodiment is compounded with a heat conducting sheet 2 and a steel plate 3 in sequence, and the compounding process is brazing. The heat conducting sheet can be a heat conducting material such as an aluminum sheet or a copper sheet. The thickness of the heat conducting sheet 2 is 0.5 to 8 mm, and the thickness of the steel plate 3 is 0.3 to 1.0 mm. The outer surface of the steel plate 3 is provided with a concave-convex pattern 31, and a non-stick pan coating is sprayed on the concave-convex pattern 31. For a better decorative effect, the concave-convex pattern 31 is a polygonal pattern with a uniform matrix distribution, and of course it can also be an irregular pattern.

[0026] In order to make the pot body 1 heat more evenly, the bottom of the pot body 1 and / or the surface of the heat conducting sheet 2 are provided with concave and convex channels 4, Figure 3 In this embodiment, a grid-like concave-convex channel 4 is directly etched or punched out on the bottom of the pot body 1. According to actual needs, the concave-convex channel 4 can also be provided on both the upper and lower surfaces of the heat conducting sheet 2. Of course, the concave-convex channel 4 can also be provided on the upper or lower surface of the heat conducting sheet 2. The concave-convex channel can be in a grid or spiral shape, with an irregular pattern that can be interconnected, or a structure that is not interconnected but allows air to be evenly distributed.

[0027] Since the bottom of the pot body 1 is compounded with the heat conducting sheet 2 and the steel plate 3, the overall heat conduction performance of the pot body 1 is better and more uniform, which prevents the non-stick coating from sintering. In addition, the outer surface of the steel plate 3 is provided with a concave-convex pattern 31, which increases the contact area of ​​heat conduction, can achieve rapid temperature rise, and has high thermal efficiency. The non-stick coating is sprayed on the concave-convex pattern 31, so that the surface of the pot body is not easy to accumulate oil, and the service life of the pot body is extended.
