Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to a two-layer composite pot. Background Technology

[0002] Two-layer composite pots are generally made of two metal materials, 304 stainless steel and aluminum alloy, using a composite process followed by molding. The two composite metal layers not only possess the characteristics of the inner stainless steel layer—healthy, corrosion-resistant, rust-resistant, and non-toxic—but also the outer layer of aluminum alloy, which features fast heat conduction, high material quality, and a variety of surface treatments. Furthermore, the two-layer composite process is simpler than three-layer or multi-layer composites, requiring fewer lamination steps, resulting in lower production costs, and the two metal layers have strong interlayer bonding. However, due to limitations of traditional processes, current two-layer composite pots struggle to simultaneously address the issues of corrosion resistance, heat conduction, and structural stability.

[0021] Reference Figures 1 to 3 This application provides a two-layer composite pot, including a pot body 100. The pot body 100 includes an inner layer 110 and an outer layer 120 arranged sequentially from the inside to the outside. The inner layer 110 is made of stainless steel, and a patterned structure is formed on the surface of the inner layer 110 by micro-etching. A ceramic coating is provided in the recesses formed by the patterned structure. The outer layer 120 is made of aluminum alloy, and a metal hot melt spraying induction layer 130 is formed on the outer surface of the outer layer 120 by thermal spraying. A protective coating is provided on the outer surface of the metal hot melt spraying induction layer 130.

[0022] The two-layer composite pot described in this application embodiment has a patterned structure formed on the surface of the inner layer 110 through micro-etching, which enables a high-strength bond between the inner layer 110 and the outer layer 120. Then, a ceramic coating is provided in the recesses formed by the patterned structure, thereby further improving the bonding strength and structural stability of the two-layer composite pot. The outer surface of the outer layer 120 has a metal hot-melt spray induction layer 130 formed by thermal spraying, which forms a porous metal skeleton on the outer surface of the outer layer 120. Then, a protective coating is provided on the outer surface of the metal hot-melt spray induction layer 130, which penetrates into the porous metal skeleton, thereby achieving the three functions of heat conduction, wear resistance, and sealing in one, so as to improve the thermal conductivity and corrosion resistance of the two-layer composite pot.

[0023] The ceramic coating uses inorganic ceramic particles such as alumina, zirconium oxide, and silicon dioxide. The composition is environmentally friendly and risk-free, and it also has a non-stick effect, reducing oil residue and making it easy to clean.

[0024] Reference Figures 1 to 3 In this embodiment, the pattern structure includes a first pattern 140 and a second pattern 150. The first pattern 140 has dot-shaped protrusions 160 and first strip-shaped protrusions 170. The second pattern 150 surrounds the edge of the first pattern 140 and has second strip-shaped protrusions 180. The depth of the first pattern 140 and the second pattern 150 is 9-12 μm, the diameter of the dot-shaped protrusions 160 is 0.5 mm, and the width of the first strip-shaped protrusions 170 and the second strip-shaped protrusions 180 is 0.3 mm. The proportion of protrusions in the first pattern 140 and the second pattern 150 is 9-20%. By adopting the above structure, not only can the overall aesthetics be improved, but it also facilitates the return of grease to the bottom of the pot, making cleaning easier.

[0025] It should be noted that the first pattern 140 and the second pattern 150 can also be set as honeycomb structure protrusions, non-hexagonal structure protrusions, regular hexagonal structure protrusions, rhomboid structure protrusions, etc., which can effectively improve the aesthetics of the appearance.

[0026] It should also be noted that the pattern structure may also consist of only one or three equal numbers of patterns, and this application does not impose any restrictions on this.

[0027] It is conceivable that the metal hot melt spraying induction layer 130 is an aluminum metal hot melt spraying induction layer, and the iron particles in the metal hot melt spraying induction layer 130 have a particle size of 60-100 mesh and a porosity of 15%-25%. Of course, the metal hot melt spraying induction layer 130 can also be made of iron, martensitic stainless steel, silicon steel, iron-nickel alloy, iron-cobalt alloy, iron-aluminum alloy, iron-silicon-aluminum alloy, etc., and this application does not limit it.

[0028] It is easy to understand that the protective coating is made of rust-proof or environmentally friendly composite materials, which can improve the anti-corrosion effect and extend the service life of the two-layer composite pot.

[0029] Reference Figure 1 and Figure 2 In some embodiments of this application, the two-layer composite pot also includes a pot body 200, which is integrally formed with the pot body 100. The patterned structure extends to the pot body 200, and a metal hot-melt induction layer 130 is disposed at the bottom of the pot body 100. In the production and processing of the two-layer composite pot, the inner layer 110 and the outer layer 120 are first combined into one piece, and then the bottom of the pot body 100 and the pot body 200 are stamped and formed. Both the bottom of the pot body 100 and the pot body 200 are two-layer structures.

[0030] In some embodiments of this application, the two-layer composite pot also includes a pot body 200, which is formed by extending upward from the inner layer 110, with the pattern structure extending to the pot body 200. In this case, the outer layer 120 is connected to the middle of the inner layer 110, which can be fixed by welding or by pressing.

[0031] It is understandable that the upper edge of the pot body 200 is provided with an outward flange 210, and the top of the outward flange 210 is a smooth surface, which is conducive to cleaning and reduces the adhesion of grease.

[0032] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
