Description

Technical Field

[0001] This application relates to the technical field of kitchen utensils, and particularly relates to a cooking pot and a cooking container. Background Art

[0002] Currently, in non-stick cookware, a ceramic coating is provided on a metal substrate to reduce the phenomenon of sticking during cooking. The material of the metal substrate is relatively soft, and when scratched by a spatula, the metal substrate is prone to deformation. The ceramic coating is hard and brittle, and after the metal substrate is deformed, the supporting effect on the ceramic coating is poor, resulting in poor scratch resistance of the ceramic coating attached to the metal substrate. In related technologies, by increasing the thickness of the metal substrate, the amount of deformation of the metal substrate when subjected to external forces is reduced, thereby reducing the possibility of the ceramic coating being scratched. However, a larger thickness of the metal substrate will increase the weight of the cookware, making it inconvenient to use, and at the same time, the cost will also increase. Summary of the Utility Model

[0003] This application provides a cooking pot and a cooking utensil for solving the problem of a relatively large thickness of the metal substrate and a heavy cooking pot.

[0004] An embodiment of this application provides a cooking pot, which includes:

[0005] A main body part, on both the inner and outer sides of which a dense oxide layer is provided;

[0006] A ceramic layer, which is respectively provided on both the inner and outer sides of the main body part, and the ceramic layer is located on the side of the oxide layer away from the main body part;

[0007] Wherein, the hardness of the oxide layer is greater than the hardness of the main body part.

[0008] Dense oxide layers are provided on both the inner and outer sides of the main body part. The oxide layer has a relatively high hardness, which can improve the hardness and corrosion resistance of the main body part, reduce the thickness of the main body part, thereby reducing the weight of the cooking pot, making it convenient to use, and also reducing the production cost of the cooking pot. A ceramic layer is provided on the main body part, which improves the wear resistance, heat resistance and corrosion resistance of the cooking pot. At the same time, the ceramic layer does not contain harmful elements such as fluorine, making the cooking pot more environmentally friendly and healthier. Ceramic layers are provided on both the inner and outer sides of the main body part. The ceramic layer on the inner side of the main body part can reduce the possibility of sticking to the inner side of the cooking pot during cooking, and the ceramic layer on the outer side of the main body part makes the outer side of the main body part smoother and more convenient to clean. The ceramic layer is hard and brittle. By arranging the ceramic layer on the oxide layer, when the cooking pot is subjected to external forces, the oxide layer has a greater hardness and is not prone to deformation, enabling the ceramic layer to be better supported and improving the scratch resistance of the ceramic layer.

[0009] In a possible embodiment, the thickness of the oxide layer is 26 μm to 40 μm.

[0010] The thickness of the oxide layer formed on the surface can be 26μm, 30μm, 35μm, 40μm, etc., to improve the hardness of the main body. If the thickness of the oxide layer is less than 26μm, the protection effect of the oxide layer on the main body is poor, and at the same time, its wear resistance and corrosion resistance are poor; as the thickness of the oxide layer increases, the protection effect of the oxide layer on the main body will also increase, but the microhardness of the surface of the oxide layer will decrease. If the thickness of the oxide layer is greater than 40μm, when the cookware is subjected to external force, the surface of the oxide layer may be deformed, reducing the support effect on the ceramic layer and thus reducing the scratch resistance of the ceramic layer.

[0011] In a possible embodiment, the material of the main body is aluminum alloy.

[0012] Aluminum alloy has good thermal conductivity, which can quickly heat the food in the cookware, reducing the cooking time and the energy required. The density of aluminum alloy is small. Under the same size, the main body made of aluminum alloy reduces the weight of the cookware, making it convenient to use.

[0013] In a possible embodiment, the thickness of the main body is 2.6mm to 3mm.

[0014] Oxide layers are provided on both the inner and outer sides of the main body to improve the hardness of the main body. The thickness of the main body can be 2.6mm, 2.8mm, 3mm, etc. While ensuring the strength of the cookware, it also reduces the thickness of the main body, lowering the weight and production cost of the cookware. If the thickness of the main body is less than 2.6mm, the hardness of the cookware is too low, reducing the service life of the cookware; if the thickness of the main body is greater than 3mm, it increases the weight of the main body and also reduces the thermal conductivity of the cookware, making it inconvenient to use.

[0015] In a possible embodiment, the ceramic layer includes a bottom oil layer and a top oil layer. The bottom oil layer is coated on the surface of the oxide layer, and the top oil layer is located on the side of the bottom oil layer away from the oxide layer.

[0016] The bottom oil layer can enhance the adhesion between the top oil layer and the oxide layer, enabling the top oil layer to adhere more firmly to the oxide layer. The top oil layer has strong anti-stick properties, which can reduce the possibility of food sticking to the cookware. At the same time, the top oil layer also has high temperature resistance and corrosion resistance, which can extend the service life of the cookware.

[0017] In a possible embodiment, the thickness of the bottom oil layer is 16μm to 19μm.

[0018] The thickness of the primer layer can be 16μm, 17μm, 18μm, 19μm, etc., which is used to improve the adhesion between the topcoat layer and the oxide layer. If the thickness of the primer layer is less than 16μm, the bonding effect between the topcoat layer and the oxide layer will be poor. If the thickness of the primer layer is greater than 19μm, the surface effect of the primer layer will be poor, and the topcoat layer is likely to separate from the primer layer.

[0019] In a possible embodiment, the thickness of the topcoat layer is 8μm to 9μm.

[0020] The thickness of the topcoat layer can be 8μm, 8.5μm, 9μm, etc., which is used to reduce the possibility of food sticking to the cookware. If the thickness of the topcoat layer is less than 8μm, its non-stick effect will be poor. If the thickness of the topcoat layer is greater than 9μm, the adhesion of the surface of the topcoat layer will be poor, and the topcoat layer is likely to be damaged.

[0021] In a possible embodiment, the cookware includes a metal layer, and the metal layer is located outside the main body and between the oxide layer and the ceramic layer.

[0022] A metal layer is provided on the outside of the main body, so that the cookware has magnetic conductivity and can be used on an induction cooker. The metal layer is arranged between the oxide layer and the ceramic layer, so that the outer surface of the cookware is a ceramic layer, which is more convenient for cleaning.

[0023] In a possible embodiment, the main body includes a bottom wall and a side wall, and the side wall surrounds the bottom wall to enclose a cooking space, and the metal layer is correspondingly arranged with the bottom wall.

[0024] When the cookware is heated by an induction cooker, the bottom wall of the main body corresponds to the heating area of the induction cooker. The metal layer is correspondingly arranged with the bottom wall. When the cookware is placed on the induction cooker, the metal layer corresponds to the induction cooker, and the food in the cookware can be heated by the induction cooker.

[0025] The embodiment of the present application also provides a cooking container, and the cooking container includes a cookware and a lid, and the lid is buckled on the cookware, wherein the cookware is the cookware described in any one of the above.

[0026] The cookware is the cookware described in any one of the above, so the cooking container also has the above technical effects.

[0027] This application relates to a cookware and a cooking container. The cookware includes a main body. Dense oxide layers are provided on both the inner and outer sides of the main body. A ceramic layer is provided on the side of the oxide layer away from the main body. The ceramic layer located on the inner side of the main body can reduce the possibility of sticking to the inner side of the cookware during cooking. The ceramic layer located on the outer side of the main body makes the outer side of the main body smoother and more convenient to clean. The oxide layer has a high hardness. By providing oxide layers on both the inner and outer sides of the main body, while ensuring the hardness of the cookware, the possibility of deformation of the cookware can be reduced. The hard and brittle ceramic layer is provided on the oxide layer, so that the cookware is not easily deformed when subjected to external forces, and can better support the ceramic layer, improving the scratch resistance of the ceramic layer.

[0028] It should be understood that the above general description and the following detailed description are only exemplary and do not limit this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] As Figure 1 and Figure 2 shown, the embodiments of the present application provide a cookware, including a main body 1. Dense oxide layers 2 are provided on both the inner and outer sides of the main body 1. The hardness of the oxide layer 2 is greater than that of the main body 1. A ceramic layer 3 is provided on the side of the oxide layer 2 away from the main body 1, so that ceramic layers 3 are provided on both the inner and outer sides of the main body 1.

[0047] Dense oxide layers 2 are provided on both the inner and outer sides of the main body 1. The oxide layer 2 has a high hardness, which can improve the hardness and corrosion resistance of the main body 1, reduce the thickness of the main body 1, and thus reduce the weight of the cookware, making it convenient to use. It can also reduce the production cost of the cookware. A ceramic layer 3 is provided on the main body 1, which improves the wear resistance, heat resistance, and corrosion resistance of the cookware. At the same time, the ceramic layer 3 does not contain harmful elements such as fluorine, making the cookware more environmentally friendly and healthier. Ceramic layers 3 are provided on both the inner and outer sides of the main body 1. The ceramic layer 3 located on the inner side of the main body 1 can reduce the possibility of sticking to the inner side of the cookware during cooking. The ceramic layer 3 located on the outer side of the main body 1 makes the outer side of the main body 1 smoother and easier to clean. The ceramic layer 3 has a high hardness and is brittle. The ceramic layer 3 is provided on the oxide layer 2. When the cookware is subjected to an external force, the oxide layer 2 has a greater hardness and is not easily deformed, enabling the ceramic layer 3 to be better supported and improving the scratch resistance of the ceramic layer 3.

[0048] In a possible embodiment, the material of the main body 1 is aluminum alloy.

[0049] Aluminum alloy has good thermal conductivity, which can quickly heat the food in the cookware, reducing the cooking time and the required energy. Aluminum alloy has a relatively small density. Under the same size, the main body 1 made of aluminum alloy reduces the weight of the cookware, making it convenient to use.

[0050] In a possible embodiment, the thickness of the main body 1 is 2.6 mm to 3 mm.

[0051] Oxide layers 2 are provided on both the inner and outer sides of the main body 1 to increase the hardness of the main body 1. The thickness of the main body 1 can be 2.6 mm, 2.8 mm, 3 mm, etc. While ensuring the strength of the cookware, it also reduces the thickness of the main body 1, lowering the weight and production cost of the cookware. If the thickness of the main body 1 is less than 2.6 mm, the hardness of the cookware is too low, reducing the service life of the cookware; if the thickness of the main body 1 is greater than 3 mm, it increases the weight of the main body 1 and also reduces the thermal conductivity of the cookware, making it inconvenient to use.

[0052] The main body 1 is made of aluminum alloy and is formed by stretching or spinning, so that the main body 1 includes a bottom wall 11 and a side wall 12. The side wall 12 is arranged around the bottom wall 11, enclosing a cooking space. Then, sandblasting treatment is carried out on both the inner and outer sides of the main body 1 to increase the roughness of both the inner and outer sides of the main body 1, enabling the ceramic layer 3 to adhere more firmly to the main body 1. Then, the sandblasted main body 1 is placed in an electrolyte for hard anodizing treatment to form a dense oxide film on the surface of the main body 1, increasing the hardness of the main body 1. It is not easily deformed when subjected to external forces and can provide support for the ceramic layer 3, thereby improving the scratch resistance of the ceramic layer 3.

[0053] As Figure 2 shown, in a possible embodiment, the thickness of the oxide layer 2 is 26 μm to 40 μm.

[0054] After the main body 1 undergoes hard anodizing treatment, the thickness of the oxide layer 2 formed on the surface can be 26 μm, 30 μm, 35 μm, 40 μm, etc., to increase the hardness of the main body 1. If the thickness of the oxide layer 2 is less than 26 μm, the protective effect of the oxide layer 2 on the main body 1 is poor, and at the same time, its wear resistance and corrosion resistance are poor; as the thickness of the oxide layer 2 increases, the protective effect of the oxide layer 2 on the main body 1 also increases, but the microhardness on the surface of the oxide layer 2 will decrease. If the thickness of the oxide layer 2 is greater than 40 μm, when the cookware is subjected to external forces, the surface of the oxide layer 2 may be deformed, reducing the support effect on the ceramic layer 3 and thereby reducing the scratch resistance of the ceramic layer 3.

[0055] As Figure 2As shown, in a possible embodiment, after an oxide film is formed on the surface of the main body 1, the outer side of the main body 1 is subjected to thermal spraying. After the metal is heated and melted, it is sprayed onto the oxide layer 2 on the outer side of the main body 1 under the drive of compressed air to form a metal layer 4. Then, a ceramic layer 3 is provided so that the metal layer 4 is located between the oxide layer 2 and the ceramic layer 3.

[0056] The material of the main body 1 is aluminum alloy. A metal layer 4 is provided on the outer side of the main body 1 to make the cookware magnetic and capable of being used on an induction cooker. By thermal spraying, the metal layer 4 is formed on the surface of the oxide layer 2, which is more tightly combined with the oxide layer 2, reducing the possibility of the metal layer 4 falling off. The metal layer 4 is arranged between the oxide layer 2 and the ceramic layer 3, so that the outer surface of the cookware is the ceramic layer 3, which is more convenient to clean.

[0057] In a possible embodiment, the bottom wall 11 of the main body 1 can be a planar structure. When the cookware is heated by an induction cooker, the bottom wall 11 of the main body 1 corresponds to the heating area of the induction cooker. The metal layer 4 is arranged corresponding to the bottom wall 11. When the cookware is placed on the induction cooker, the metal layer 4 corresponds to the induction cooker, enabling the food in the cookware to be heated by the induction cooker.

[0058] As Figure 2 shown, the ceramic layer 3 includes an undercoat layer 31 and a topcoat layer 32. The undercoat layer 31 is coated on the surface of the oxide layer 2, and the topcoat layer 32 is located on the side of the undercoat layer 31 away from the oxide layer 2. When setting the ceramic layer 3, the undercoat layer 31 is first sprayed on the surface of the oxide layer 2. After the surface of the undercoat layer 31 is dried, the topcoat layer 32 is sprayed on the surface of the undercoat layer 31, and finally it is put into a heating furnace for sintering to form a ceramic layer 3 with a smooth surface.

[0059] The main component of the undercoat layer 31 is polyamideimide. The amide bond and imide bond in polyamideimide can enhance the adhesion between the topcoat layer 32 and the oxide layer 2, enabling the topcoat layer 32 to adhere more firmly to the oxide layer 2. The main component of the topcoat layer 32 is polytetrafluoroethylene. The molecular structure of polytetrafluoroethylene has non-polar bonds. The bonding ability between the two fluorine atoms on the surface is strong, and the surface free energy is very low. Therefore, it has strong anti-adhesion, which can reduce the possibility of food sticking to the cookware. At the same time, polytetrafluoroethylene also has high temperature resistance and corrosion resistance, which can extend the service life of the cookware.

[0060] In a possible embodiment, the thickness of the undercoat layer 31 is 16 μm to 19 μm.

[0061] The thickness of the primer layer 31 can be 16 μm, 17 μm, 18 μm, 19 μm, etc., which is used to improve the adhesion ability between the topcoat layer 32 and the oxide layer 2. If the thickness of the primer layer 31 is less than 16 μm, the bonding effect between the topcoat layer 32 and the oxide layer 2 will be poor. If the thickness of the primer layer 31 is greater than 19 μm, the surface effect of the primer layer 31 will be poor, and the topcoat layer 32 is likely to separate from the primer layer 31.

[0062] In a possible embodiment, the thickness of the topcoat layer 32 is 8 μm to 9 μm.

[0063] The thickness of the topcoat layer 32 can be 8 μm, 8.5 μm, 9 μm, etc., which is used to reduce the possibility of food sticking to the cookware. If the thickness of the topcoat layer 32 is less than 8 μm, its non-stick effect will be poor. If the thickness of the topcoat layer 32 is greater than 9 μm, the adhesion force on the surface of the topcoat layer 32 will be poor, and the topcoat layer 32 is likely to be damaged.

[0064] The embodiment of the present application also provides a cooking container, which includes a cookware and a lid fastened to the cookware. The cookware is the cookware described in any one of the above, so the cooking container also has the above technical effects.

[0065] The present application relates to a cookware and a cooking container. The cookware includes a main body 1. Dense oxide layers 2 are provided on both the inner and outer sides of the main body 1. A ceramic layer 3 is provided on the side of the oxide layer 2 away from the main body 1. The ceramic layer 3 located on the inner side of the main body 1 can reduce the possibility of the inner side of the cookware sticking during cooking. The ceramic layer 3 located on the outer side of the main body 1 makes the outer side of the main body 1 smoother and more convenient to clean. The oxide layer 2 has a high hardness. Dense oxide layers 2 are provided on both the inner and outer sides of the main body 1, which can reduce the possibility of the cookware deforming while ensuring the hardness of the cookware. The hard and brittle ceramic layer 3 is provided on the oxide layer 2. When the cookware is subjected to external forces, it is not easy to deform, and can better support the ceramic layer 3, improving the scratch resistance of the ceramic layer 3.

[0066] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
