[0010] In some embodiments, the first inorganic substrate is 10Cr17 stainless steel, which has high strength and corrosion resistance, so that good impact resistance and corrosion resistance can be provided to protect the pot from wear and corrosion in daily use. The second inorganic substrate is 06Cr19Ni10 stainless steel, so that excellent corrosion resistance and certain non-stickiness are ensured, and food safety standards are met. The aluminum substrate is aluminum alloy or pure aluminum, which can take advantage of the high thermal conductivity of aluminum material to provide excellent heat conduction performance, so that the heat of the pot is quickly and uniformly distributed, thereby improving the cooking efficiency.

[0034] The cookware according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings. Figures 1 to 5

[0035] According to a first aspect of the present disclosure, a cookware is provided, wherein, as shown in Figure 1 and Figure 2 The cookware according to the embodiments of the present disclosure includes an aluminum composite base material 10 and a non-stick layer 20, and the non-stick layer 20 is arranged on the aluminum composite base material 10.

[0036] The cookware according to the embodiments of the present disclosure has good thermal conductivity due to the aluminum composite base material 10, so that it can quickly and uniformly conduct heat, so that the cookware can reach a uniform temperature faster during cooking, avoid the phenomenon of sticking to the pot due to uneven local temperature, and improve the uniformity of the heat of the cookware during cooking. The cooking effect and cooking efficiency of the cookware can be improved. In addition, the non-stick layer is also arranged on the aluminum composite base material to ensure good non-stickness of the cookware, which can further reduce the phenomenon of sticking to the pot, thereby ensuring the cooking effect and cooking efficiency.

[0037] ​In the utility model, the composite form of the aluminum composite base material 10 is diversified. In some embodiments, the aluminum composite base material 10 has a layered composite form, that is, a multilayer structure formed by alternately stacking aluminum material layers and other material layers. In other embodiments, the aluminum composite base material 10 has an aluminum particle doped composite form, that is, uniformly dispersing aluminum particles in an inorganic matrix layer. Both of the above two composite forms can effectively utilize the heat conduction performance of aluminum material, thereby improving the heat conduction speed and heat conduction uniformity of the pot and ensuring the heat conduction performance of the pot.

[0038] According to some embodiments of the present application, the aluminum composite base material 10 comprises a first inorganic base material 11, an aluminum base material 12 and a second inorganic base material 13 arranged in sequence, the outer surface of the first inorganic base material 11 serves as the outer wall surface of the pot, the second inorganic base material 13 is connected with the non-stick layer 20, and the thermal conductivity of the aluminum base material 12 is greater than the thermal conductivity of the first inorganic base material 11 and the second inorganic base material 13 respectively. In these embodiments, the aluminum base material 12 is arranged between the first inorganic base material 11 and the second inorganic base material 13, and it can also be understood that the aluminum composite base material 10 comprises a layered composite structure formed by stacking the first inorganic base material 11, the aluminum base material 12 and the second inorganic base material 13. Here, the first inorganic base material 11 can provide basic strength, corrosion resistance and magnetic permeability. The aluminum base material 12 serves as a heat conduction layer in the layered composite structure, can utilize the high thermal conductivity of aluminum material, and can provide excellent heat conduction performance, so that the heat of the pot is quickly and uniformly distributed, thereby improving the cooking efficiency. The second inorganic base material 13 does not directly contact with food, and indirectly provides corrosion resistance and certain non-stick performance basis.

[0039] According to other embodiments of the utility model, the aluminum composite base material 10 comprises an inorganic matrix layer and aluminum material particles dispersed in the inorganic matrix layer. Here, the inorganic matrix layer can be a metal layer or a ceramic layer.

[0040] In the following, the aluminum composite base material 10 with a layered composite structure will be specifically described.

[0041] In some embodiments, the aluminum composite base material 10 has a layered composite structure, and the layers are tightly combined, so that heat can be better transferred and absorbed, thereby improving the heat conduction speed and heat conduction uniformity of the pot.

[0042] In some embodiments, the thermal conductivity of the aluminum composite base material 10 is 100W / m·K-200W / m·K. The thermal conductivity between the layers can be set within a certain range, so that the heat conduction performance of the aluminum composite base material 10 as a whole can be improved by means of the thermal conductivity of the layers. As a specific example, the thermal conductivity of the aluminum base material 12 is between 150W / m·K-237W / m·K, the thermal conductivity of the first inorganic base material 11 is between 15W / m·K-60W / m·K, and the thermal conductivity of the second inorganic base material 13 is between 15W / m·K-60W / m·K.

[0043] In some embodiments, the total thickness of the aluminum composite base 10 is 1.0 mm to 2.5 mm. The aluminum composite base 10 having such thickness can balance the strength, weight, and heat transfer efficiency of the manufactured pot, and the like. In addition, the aluminum composite base 10 having a certain thickness can easily withstand the process requirements of subsequent processes such as nitriding and oxidation. For example, if the thickness of the aluminum composite base 10 is too thin, it can be easily deformed by high temperature during the nitriding process, and if the thickness of the aluminum composite base 10 is too thick, the manufactured pot can be too heavy and affect the heat transfer effect.

[0044] Further, the first inorganic base 11 has a thickness d1 of 0.1 mm ≤ d1 ≤ 0.5 mm, the aluminum base 12 has a thickness d2 of 0.8 mm ≤ d2 ≤ 1.6 mm, and the second inorganic base 13 has a thickness d3 of 0.1 mm ≤ d3 ≤ 0.5 mm.

[0045] In these embodiments, the thickness of each part of the aluminum composite base 10 can optimize the heat transfer performance to some extent, ensure the uniformity of the pot when in use, and avoid the phenomenon of sticking the pot due to excessively high or low temperature. In addition, the pot can quickly reach a uniform temperature during cooking, which can improve the uniformity of the pot in cooking food, thereby improving the taste of the cooked food.

[0046] In some embodiments, the first inorganic base 11 includes one of a steel base, an iron base, a titanium base, a titanium-iron-aluminum composite base, a steel-iron-steel composite base, a steel-titanium composite base, an iron-titanium composite base, and a ceramic base. The second inorganic base 13 includes one of a steel base, an iron base, a titanium base, a titanium-iron-aluminum composite base, a steel-iron-steel composite base, a steel-titanium composite base, an iron-titanium composite base, and a ceramic base.

[0047] In these embodiments, the types of the first inorganic base 11 and the second inorganic base 13 are diversified, and thus, a plurality of types of pots can be manufactured based on actual needs, thereby widening the range of pots.

[0048] As a specific example, the aluminum composite base 10 is a layered composite structure in which a stainless steel inner layer, an aluminum base 12, and a stainless steel outer layer are stacked. The high-temperature stability of the inner and outer layers of stainless steel enables the pot to maintain stable performance in a high-temperature environment and is not easily deformed or damaged.

[0049] In preferred embodiments, the inner layer of stainless steel can be made of high-quality food-grade stainless steel material, for example, 06Cr19Ni10 stainless steel, so as to ensure excellent corrosion resistance and certain non-stickiness, while meeting food safety standards. The outer layer of stainless steel can be made of high-strength stainless steel, for example, 10Cr17 stainless steel, which has high strength and corrosion resistance, so as to provide good impact resistance and corrosion resistance to protect the pot from wear and corrosion in daily use.

[0050] According to the present application, the aluminum base material 12 is not only arranged at the bottom of the pot, but also extends to cover the wall area of the pot. In some embodiments, the height of the pot is H, and the aluminum base material 12 covers at least 1 / 3H of the wall position corresponding to the pot from the bottom of the pot. In this way, the heat conduction performance of the cooking function area (food material action area) of the pot is good, and the phenomenon of sticking to the pot due to uneven heating is avoided.

[0051] In use, when the pot is placed on a heat source, heat is absorbed from the center area of the bottom of the pot, the first inorganic base material 11 absorbs heat and transfers heat to the aluminum base material 12, and then the aluminum base material 12 quickly transfers heat to quickly distribute the absorbed heat to the bottom wall and the peripheral part of the pot, improving the conduction efficiency, so that the pot can quickly reach a uniform temperature during cooking and reduce the occurrence of hot spots and cold spots, to achieve efficient heat conduction, uniform temperature distribution, and physical temperature control effect, thereby ensuring cooking efficiency and food taste.

[0052] In some embodiments, the aluminum base material 12 completely covers the bottom and the wall of the pot, so that heat can be better distributed, and the manufacturing process of the pot can be simplified.

[0053] According to the pot of the present application, heat can be directly and efficiently transferred from the center of the bottom of the pot to each area of the pot through the aluminum base material 12, improving cooking efficiency and food material heating uniformity, and improving cooking efficiency and food taste. In the process of continuous heating, the aluminum base material 12 can also balance the temperature difference between the bottom and the wall of the pot, realize rapid and uniform heat conduction, and further improve the cooking efficiency and the food taste.

[0054] According to the present application, the non-stick layer 20 is one of an inorganic non-stick layer, a fluorine coating layer, and a ceramic coating layer. The inorganic non-stick layer is specifically a non-stick layer formed by inorganic matter, for example, it can include a titanium-iron alloy layer, a titanium layer, an iron layer, or an inorganic non-metallic ceramic material layer.

[0055] In the embodiments, the non-stick layer 20 has good non-stick performance, avoiding the pot from sticking after use. In addition, the non-stick layer 20 has high strength, hardness, and good corrosion resistance and high temperature resistance, so that the overall durability of the pot can be enhanced, the service life is prolonged, and the replacement frequency is reduced.

[0056] In some embodiments, the non-stick layer 20 includes one of a titanium-iron alloy layer, a titanium layer, an iron layer, and an inorganic non-metallic ceramic material layer, and the non-stick layer 20 has excellent wear resistance and smoothness, which can further enhance the non-stick performance of the pot. It should be noted that in the present application, the titanium-iron alloy layer, the titanium layer and the iron layer are layers formed by corresponding titanium-iron alloy, titanium or iron materials in the prior art.

[0057] In the embodiments, the types of the non-stick layer 20 are diversified, which can meet the cooking needs of the pot.

[0058] In some embodiments, the thickness of the non-stick layer 20 is d4, wherein 25 microns ≤ d4 ≤ 100 microns, and the non-stick layer 20 with such thickness can balance the non-stick performance, wear resistance and bonding performance with the aluminum composite substrate 10 and other aspects.

[0059] According to the first aspect of the present application, in the case that the non-stick layer 20 is a metal layer (titanium layer, iron layer or titanium-iron alloy layer), the surface layer of the non-stick layer 20 also has a nitriding treatment layer 21. As shown in Figure 3 The pot includes an aluminum composite substrate 10 and a non-stick layer 20 formed on the aluminum composite substrate 10, and the surface layer of the non-stick layer 20 also has a nitriding treatment layer 21.

[0060] According to the second embodiment of the present application, in the case that the non-stick layer 20 is a metal layer (titanium layer, iron layer or titanium-iron alloy layer), the non-stick layer 20 has a nitriding treatment layer 21 and an oxidation treatment layer 22. As shown in Figure 4 The pot includes an aluminum composite substrate 10 and a non-stick layer 20, and the surface layer of the non-stick layer 20 has a nitriding treatment layer 21, and the surface of the nitriding treatment layer 21 also has an oxidation treatment layer 22.

[0061] In the following, the pot provided by the first embodiment of the present application will be specifically introduced in combination with the embodiments.

[0062] According to the present application, the nitriding treatment layer 21 is a nitride generated by the reaction of the non-stick layer 20 and nitrogen. Specifically, the pot with the non-stick layer 20 is exposed to a nitrogen-containing atmosphere (such as nitrogen or ammonia gas, etc.), and the metal (iron and / or titanium) in the non-stick layer 20 reacts with nitrogen at high temperature to form a nitriding film on the surface of the non-stick layer 20, thereby improving the strength, hardness and corrosion resistance, and further enhancing the non-stick performance.

[0063] In some embodiments, the nitriding treatment layer 21 has a certain depth, which can improve the corrosion resistance and hardness of the obtained cookware without affecting the performance of the aluminum composite substrate 10 (excessive nitriding of the substrate will make it brittle).

[0064] According to the present application, the cookware with the non-stick layer 20 is subjected to nitriding treatment, so that the surface layer of the non-stick layer 20 has the nitriding treatment layer 21. Specifically, the cookware with the non-stick layer 20 is placed in a nitriding furnace, and the temperature of the nitriding furnace is set to 550-600°C. At the same time, nitrogen gas is introduced for 3-4h, and nitrogen atoms will chemically react with metal elements in the surface layer of the non-stick layer 20 to form hard compounds such as iron nitride Fe3N, thereby obtaining a cookware with a nitriding treatment layer 21 having a thickness of 12-25 microns.

[0065] In these embodiments, through nitriding treatment, the surface layer of the non-stick layer 20 forms a dense nitriding treatment layer 21, which has high hardness and strength, and can significantly improve the wear resistance and corrosion resistance of the cookware, and ensure the durability of the non-stick performance. In addition, the nitriding treatment layer 21 can effectively prevent the penetration of corrosive substances in the external environment, thereby slowing down or preventing the occurrence of corrosion reactions, and further improving the corrosion resistance of the cookware.

[0066] In the following, the cookware provided by the second embodiment of the present application will be specifically described in conjunction with the embodiments.

[0067] According to the present application, the non-stick layer 20 has a nitriding treatment layer 21 and an oxidation treatment layer 22, wherein the nitriding treatment layer 21 is arranged on the surface layer of the non-stick layer 20, and the oxidation treatment layer 22 is arranged on the nitriding treatment layer 21 and serves as the surface layer of the cookware. The oxidation treatment layer 22 has high hardness, which can significantly improve the wear resistance and scratch resistance of the cookware. In addition, the oxidation treatment layer 22 is relatively dense, which can effectively prevent the contact of corrosive media with the aluminum composite substrate 10, thereby improving the corrosion resistance of the cookware. In addition, the oxidation treatment layer 22 can remain stable at high temperatures and is not prone to decomposition or falling off, and therefore can be suitable for high-temperature cooking environment of the cookware.

[0068] It should be noted that according to the second aspect of the present application, in addition to the oxidation treatment layer 22 compared with the first aspect of the present application, other aspects can be referred to the related description of the first aspect of the present application. In the following, the differences will be specifically described, and the same will not be described again.

[0069] In some embodiments, the oxidation treatment layer 22 has a depth, on one hand, capable of improving the wear resistance of the cookware with the oxidation treatment layer 22 without affecting the basic performance of the substrate, and capable of controlling the cost. On the other hand, capable of forming black oxides without the iron-containing layer 20, so that the overall appearance of the cookware is black, which helps to improve the appearance and texture of the cookware. As an example, the oxidation treatment layer 22 has a formation depth d6, wherein 15 microns ≤ d6 ≤ 30 microns.

[0070] It should be noted that the utility model does not have special requirements for the content of each component of the oxidation treatment layer 22 after oxidation treatment, and those skilled in the art can perform oxidation treatment on the nitriding treatment layer 21 for a certain time under a certain oxygen atom concentration to obtain the oxidation treatment layer 22 according to the utility model.

[0071] According to the utility model, the cookware further comprises a grease sintering layer formed on the pores and / or surface of the non-stick layer 20, so that the non-stick performance of the cookware can be further improved.

[0072] In the manufacturing method of the cookware, the step of oil sintering is included, specifically, a layer of mixed oil can be uniformly applied on the nitriding treatment layer 21 of the cookware after nitriding treatment, and then drying and oil collection treatment is performed, and then sintering is performed at a temperature of 250-300 DEG C, this step is repeated twice or more times, then, after oxidation treatment, oil sintering can be performed again, so that the pores and / or surface of the non-stick layer 20 will form a grease sintering layer, thereby further improving the non-stick performance of the cookware and ensuring the cooking quality of the cookware.

[0073] According to the utility model, as shown in Figure 5 The surface of the aluminum composite substrate 10 combined with the non-stick layer 20 is provided with a concave-convex structure, and the non-stick layer 20 is arranged on the concave-convex structure, so that the surface of the non-stick layer 20 has an oil storage groove 23, and the surface of such cookware can store oil to further improve the non-stick performance. In addition, the surface of the non-stick layer 20 has an oil storage groove 23, which can reduce the contact area between the spatula and the inner wall surface of the cookware, thereby increasing the service life and achieving the effect of enhancing the non-stick performance.

[0074] Here, the concave-convex structure on the aluminum composite substrate 10 can be obtained by etching. According to the manufacturing method of the cookware of the present application, the concave-convex structure on the inner surface of the substrate can be prepared by etching, laser engraving, stamping or the like. As an example, a 5000T stamping device is used to stamp on one side of a circular sheet to obtain a concave-convex structure of a predetermined size.

[0075] In some embodiments, the height of the protrusion is H1, wherein 80 microns≤H1≤200 microns; the width of the protrusion is W1, wherein 0.3 millimeter≤W1≤3 millimeters. The depth of the groove is H2, wherein 80 microns≤H2≤200 microns; the width of the groove is W2, wherein 0.3 millimeter≤W2≤3 millimeters. With such a concave-convex structure, the non-stick layer 20 formed thereon has a suitable oil storage groove 23, thereby improving the non-stick performance of the pot and ensuring the cooking quality of the pot.

[0076] According to the utility model, through the strong heat conduction capacity of aluminum material, the pot can effectively realize the rapid and uniform distribution of temperature when heating, which is helpful for the uniform heating of food materials during cooking, so that the pot has excellent heat conduction performance, heat can be uniformly and rapidly transmitted to the whole pot body, and the cooking efficiency and effect are improved.

[0077] In addition, the non-stick layer 20 has a certain non-stick property, and at the same time, the non-stick layer 20 forms a surface with an oil storage groove 23, which can support food materials and store oil, thereby realizing the effect of double non-stick superposition.

[0078] In addition, the non-stick layer 20, the nitriding treatment layer 21 and the oxidation treatment layer 22 are sequentially formed, which enhances the smoothness, hardness and corrosion resistance of the pot, improves the wear resistance of the pot, and prolongs the service life.

[0079] Although the embodiments of the utility model have been described in detail above, those skilled in the art can make various modifications and changes to the embodiments of the utility model without departing from the spirit and scope of the utility model. However, it should be understood that these modifications and changes will still fall within the spirit and scope of the embodiments of the utility model defined by the claims.
