[0008] In some embodiments, the central region of the inner bottom wall of the pot body is concave relative to the outer edge of the inner bottom wall of the pot body, so that the inner bottom wall of the pot body is formed into the first concave arc surface.

[0009] In these embodiments, the central region of the inner bottom wall of the pot body is concave inward relative to the outer edge of the inner bottom wall of the pot body, so that in use, the oil in the pot can flow more naturally to the central region of the inner bottom wall to form an oil film, so that the pot is non-stick and reduces oil consumption. In addition, by providing a concave in the central region of the inner bottom wall of the pot body, compared with other regions, the central local overheating of the food material can be largely avoided.

[0010] In some embodiments, the depth of the concave in the central region of the inner bottom wall of the pot body is 1.3%-1.5% of the diameter D1 of the inner bottom wall of the pot body.

[0031] The specific embodiments of the present application are described in detail, although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and improved without departing from the principles and spirits of the present application limited by the claims and their equivalents.

[0032] The pot according to the embodiments of the present application will be described in detail below with reference to Figure 1 and Figure 2 .

[0033] The present application provides a pot, specifically a composite pot. As shown in Figures 1 to 2 , the pot includes a pot body 10 and a composite bottom 20, the composite bottom 20 is formed on the outer bottom wall of the pot body 10, and includes a magnetic conductive layer 22 and an aluminum intermediate bottom 21 which is stacked between the magnetic conductive layer 22 and the bottom wall of the pot body 10.

[0034] According to the pot provided by the utility model, the outer bottom wall of the pot body 10 is connected with a composite bottom 20, the composite bottom 20 comprises a magnetic conductive layer 22 and an aluminum intermediate bottom 21, wherein the magnetic conductive layer 22 is used for ensuring the magnetic conductive performance of the pot, and the aluminum intermediate bottom 21 serves as a bridge connecting the magnetic conductive layer 22 and the bottom wall of the pot body 10, thereby not only ensuring the close combination between the layers of the composite pot, but also significantly reducing the overall weight of the pot due to the light weight of the aluminum intermediate bottom 21. Therefore, the pot according to the utility model can have the advantages of light weight and magnetic conductive function.

[0035] According to the utility model, the pot is a frying pan or a wok, and the types are diversified, so that diversified cooking requirements can be met.

[0036] In some embodiments, the pot body 10 is an aluminum pot body or a ceramic pot body, and the weight of the pot body 10 in the above form is light, so that the overall weight of the pot can be significantly reduced.

[0037] In some embodiments, the inner bottom wall of the pot body 10 is concave and forms a first concave arc surface, and here, the first concave arc surface serves as the inner surface of the bottom wall of the pot.

[0038] In these embodiments, the inner surface of the bottom wall of the pot is a concave arc surface, and in the cooking process, oil is easily collected, so that the amount of oil required when cooking the same amount of food is greatly reduced, and the food after cooking is ensured to be less oily, thereby meeting the health demand of people for less oil.

[0039] In some embodiments, the central region of the inner bottom wall of the pot body 10 is concave relative to the outer edge of the inner bottom wall of the pot body 10, so that the composite bottom 20 and the outer wall surface of the pot body 10 form a first concave arc surface.

[0040] In these embodiments, the central region of the inner bottom wall of the pot body 10 is concave relative to the outer edge of the inner bottom wall of the pot body 10, so that in use, the oil in the pot can flow more naturally to the central region of the inner bottom wall to form an oil film, so that the pot is non-stick and the oil consumption is reduced. In addition, by providing the concave in the central region of the inner bottom wall of the pot body 10, compared with other regions, the food can be prevented from being scorched due to local overheating in the center to a great extent.

[0041] In some embodiments, the depth of the concave in the central region of the inner bottom wall of the pot body 10 is 1.3%-1.5% of the diameter D1 of the inner bottom wall of the pot body 10.

[0042] In these embodiments, the depth of the concave in the central region of the inner bottom wall of the pot body 10 can maximize the oil collection effect of the pot and ensure the persistence and stability of the oil collection effect. Sufficient concave depth can ensure the uniform distribution and effective utilization of oil during the cooking process of the pot, thereby improving the taste and quality of the cooked food.

[0043] It is known that the inner bottom wall of the pot used for the electromagnetic oven will be upwardly convex in the middle region when used for a long time on the open fire heating source, thus causing the failure of the oil collecting groove, and the phenomenon of oil not being collected in the middle of the pot, or even running out. When used for a long time on the electromagnetic heating source, the inner bottom wall of the pot will be downwardly convex in the middle region, thus deepening the oil collecting groove, but the bottom center will be outwardly convex, thus causing the pot to spin on the surface of the electromagnetic plate, and thus causing the pot to be unable to be normally used.

[0044] According to the utility model, the central region of the outer wall surface of the composite bottom 20 is upwardly convex relative to the outer edge of the outer wall surface of the composite bottom 20, thus forming a second concave arc surface on the outer wall surface of the composite bottom 20, and the second concave arc surface is used as the outer surface of the bottom wall of the pot.

[0045] Here, it should be noted that, in general, the inner surface of the bottom wall of the pot is concave, and the outer surface of the bottom wall is downwardly convex, that is, if the inner surface of the bottom wall of the pot is concave, then the outer surface of the bottom wall of the pot is convex. In the utility model, the inner surface of the bottom wall of the pot is concave, and the outer surface of the bottom wall of the pot is upwardly convex. That is, the inner surface and the outer surface of the bottom wall of the pot are both concave, and such a structure can not only ensure the oil collecting effect of the pot, but also ensure the durability of the magnetic guiding function of the pot.

[0046] In the manufacture of the pot according to the utility model, the inner surface and the outer surface of the bottom wall of the pot can be formed respectively. For example, in the first stage, the inner bottom wall of the pot body 10 can be formed to be concave, and since the aluminum intermediate bottom 21 is arranged between the magnetic guiding layer 22 and the bottom wall of the pot body 10, and the aluminum intermediate bottom 21 has good plasticity, in the second stage, the concave inner bottom wall of the pot body 10 can be kept by a pre-set mold, and then the aluminum intermediate bottom 21 between the magnetic guiding layer 22 and the bottom wall of the pot body 10 can be deformed under the action of external force, so as to form the upward convexity on the lower surface of the magnetic guiding layer 22, thus obtaining the pot structure of the utility model.

[0047] In these embodiments, in use, the outer edge of the outer wall surface of the composite bottom 20 can support the pot to ensure that the bottom surface of the pot is closely attached to the plane of the electromagnetic oven, thus obtaining the magnetic guiding capability, and the central region of the outer wall surface of the composite bottom 20 can provide a certain deformation space for the outward convexity of the pot when used on the electromagnetic oven, so as to avoid the electromagnetic function failure caused by the outward convexity of the pot in use, thus improving the adaptability and durability of the pot.

[0048] In some embodiments, the central region of the outer wall surface of the composite bottom 20 is upwardly convex by 0.2%-0.6% of the diameter D2 of the outer wall surface.

[0049] In these embodiments, the central region of the outer wall surface of the composite bottom 20 is convex upward by a certain height, which can ensure sufficient deformation space and relieve the situation of the bottom center of the pot being convex upward for as long as possible when the pot is used on the induction cooker, thereby ensuring the service life of the electromagnetic function of the pot.

[0050] In some embodiments, the thickness of the aluminum intermediate bottom 21 is reduced from the outer edge of the bottom wall of the pot toward the middle of the bottom wall of the pot, and the thickness of the bottom wall of the pot is also reduced. Specifically, the thickness of the aluminum intermediate bottom is gradually reduced, and the thickness of the bottom wall of the pot is gradually reduced.

[0051] In these embodiments, the thickness of the aluminum intermediate bottom 21 gradually decreases from the outer edge of the bottom wall of the pot toward the middle, and at the same time, the thickness of the bottom wall of the pot itself also follows the same decreasing rule. Such thickness gradient design can optimize the heat conduction efficiency of the pot, improve the cooking efficiency, and balance the weight and combination of the pot.

[0052] In some embodiments, the side wall of the composite bottom and the side wall of the pot body 10 are smoothly transitioned and jointly serve as the side wall of the pot. In this way, not only the elegant and smooth appearance of the pot is given, which greatly improves the aesthetics, but also the interface gap on the outer wall is reduced, which effectively prevents food residues or dirt from being trapped in the interface gap during use of the pot, thereby simplifying the daily cleaning and maintenance of the pot and ensuring that the pot remains clean and new for a long time, providing users with a more convenient and sanitary cooking experience.

[0053] In these embodiments, the composite bottom 20 is formed on the outer bottom wall of the pot body 10 by thermal reworking. The connection of the pot body and the composite bottom by thermal reworking can ensure the combination of the composite pot, thereby improving the service life of the pot.

[0054] In some embodiments, the pot includes an anti-corrosion coating formed on the side wall of the composite bottom and on the surface of the pot body not covered by the composite bottom.

[0055] In these embodiments, the anti-corrosion coating is provided on the outer surface of the pot, which can ensure the corrosion resistance of the pot. Especially in the case where the pot includes materials that are not resistant to corrosion, the overall corrosion resistance of the pot can be improved, and the purpose of the pot being resistant to dishwasher cleaning can be achieved.

[0056] In some embodiments, the magnetically conductive layer 22 includes nickel, iron, or cobalt, which can conduct magnetism and achieve the purpose of the pot conducting magnetism.

[0057] In some embodiments, the magnetic conductive layer 22 is a stainless steel layer. As the magnetic conductive layer 22, the stainless steel layer can not only realize the magnetic conductive performance of the pot, but also ensure the overall performance of the pot due to its hardness and corrosion resistance.

[0058] According to the method for manufacturing the pot of the utility model, the method for manufacturing the pot comprises the following steps:

[0059] Step S101, providing a pot body 10. Specifically, the pot body 10 can be formed by stretching a metal sheet, wherein the pot body 10 has a bottom wall and a side wall.

[0060] Step S102, providing a magnetic conductive layer 22 and an aluminum intermediate bottom 21. Specifically, the magnetic conductive layer 22 can be a stainless steel sheet. The aluminum intermediate bottom 21 can be an aluminum or aluminum alloy sheet.

[0061] Step S103, sequentially stacking the aluminum intermediate bottom 21 and the magnetic conductive layer 22 on the outer bottom wall of the pot body 10, thereby obtaining an initial pot.

[0062] Step S104, forming a first concave arc surface that is concave downward on the inner surface of the bottom wall of the initial pot, and then forming a second concave arc surface that is convex upward on the outer surface of the bottom wall of the initial pot under the condition that the first concave arc surface is supported by a mold.

[0063] In an embodiment, the thickness of the pot body 10 is between 1cm and 1.5cm, the thickness of the magnetic conductive layer 22 is between 0.5mm and 0.8mm, and the thickness of the aluminum intermediate bottom 21 is between 4mm and 10mm.

[0064] Specifically, the method for manufacturing the pot comprises the following steps.

[0065] First, a spot welder is used to single-point weld and fix the pot body 10, the aluminum intermediate bottom 21 and the magnetic conductive layer 22. Specifically, the voltage of the spot welder is controlled within the range of 260V~450V, the current is maintained at 10KA~35KA, and the air pressure is adjusted to 0.1MPa~0.5MPa, so as to ensure the firmness and stability of the welding point. This pretreatment step lays a solid foundation for position fixing in the subsequent process.

[0066] Then, a medium-frequency heating machine is used to heat treat the aluminum intermediate bottom 21. The power of the medium-frequency heating machine is set between 6.5KW~8.5KW, and the heating time is controlled within the range of 19s~40s, so as to ensure that the aluminum intermediate bottom 21 reaches a softened state before liquefaction. This step provides good material conditions for the subsequent forging and forming.

[0067] Subsequently, the heated pot body 10 is placed in a die of a 3000-ton friction press, and is forged and formed by the friction press to tightly bond the pot body 10, the aluminum intermediate bottom 21 and the magnetic conductive layer 22, and form a firm composite structure.

[0068] Finally, the lathe or milling machine is used to accurately remove the excess material affecting the appearance and structure of the pot after the pot is bottomed, so as to ensure the aesthetics and practicability of the product.

[0069] In some embodiments, a first concave arc surface that is concave downward can also be formed on the inner surface of the bottom wall of the pot, and a second concave arc surface that is convex upward can also be formed on the outer surface of the bottom wall of the pot.

[0070] Although the embodiments of the present application have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. However, it should be understood that these modifications and variations will still fall within the spirit and scope of the embodiments of the present application defined by the claims.
