Cookware body structure

Abstract

To provide a pot body structure for a pot that reduces the overall weight of the pot body, significantly improves resistance to corrosion caused by acidic food materials, and prevents food contamination due to elution of iron ions. The pot includes a main body 1, which has an inner surface for contacting food and an outer surface for contacting a heat source. A first ferrous layer 2 is formed toward the inner surface of the main body, and a second ferrous layer 3 is formed toward the outer surface of the main body. An aluminum layer 4 for thermal conduction is sandwiched between the first and second ferrous layers. By sandwiching the highly thermally conductive aluminum layer between the first and second ferrous layers, the low density of aluminum is utilized to replace some of the iron-based materials, directly reducing the overall weight of the main body and easing the user's frying burden. At the same time, the first nitride layer formed by nitriding on the inner surface of the pot significantly improves resistance to corrosion by acidic ingredients and prevents food contamination due to the leaching of iron ions.

Description

[Technical Field]

[0001] The present invention relates to the field of pot body technology, and more particularly to a pot body structure for a pot. [Background technology]

[0002] Iron pans, especially iron frying pans, are essential cooking tools in homes and restaurants. Their core advantages are their long service life, excellent heat conduction (fast and even heat conduction), and good maintenance characteristics, which have earned them long-standing recognition from a wide range of consumers. The natural oil film formed in iron pans at high temperatures provides a certain degree of physical non-stickiness, and they can withstand relatively high cooking temperatures, making them particularly suitable for cooking methods such as Chinese-style frying.

[0003] However, iron pots and pans have their own limitations. Iron has a relatively high density, approximately 7.87 g / cm 3 This directly contributes to the weight of traditional iron pots. An overly heavy pot body brings many inconveniences in actual use: holding it for a long time while frying can easily tire the user's wrist, which is not friendly to users with weak strength; frequent release and cleaning operations also require force due to the weight, reducing the overall user experience and operational flexibility. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention addresses the shortcomings of the prior art by providing a pot body structure. [Means for solving the problem]

[0005] To solve the above technical problems, the present invention provides the following technical solution: a pot body structure for a pot, comprising a pot body, having an inner surface for contacting food and an outer surface for contacting a heating source;

[0006] The ferrous layer is formed toward the inner surface of the pot body; The ferric layer is formed toward the outer surface of the pot body; and An aluminum layer is sandwiched between the ferrous and ferric layers to conduct heat.

[0007] In the above invention, preferably, a first nitride layer formed by nitriding is provided by covering the ferrous layer, and the first nitride layer is used as the inner surface.

[0008] In the above invention, preferably, a second nitride layer formed by nitriding is provided to cover the ferric layer, and the second nitride layer is used as the outer surface.

[0009] In the above invention, preferably, the thickness of the aluminum layer is at least 2 / 5 of the thickness of the pot body.

[0010] In the above device, preferably, the pot body is connected to the handle via a connecting piece.

[0011] In the above device, preferably, the handle includes a cast steel pipe body and a first mounting member and a second mounting member respectively connected to both sides of the cast steel pipe body.

[0012] In the above device, preferably, the first and second mounting members are provided with holes for reducing weight.

[0013] In the above invention, preferably, the connecting part is a flat head iron rivet. [Effects of the Invention]

[0014] The present invention has the following beneficial effects: By sandwiching a highly thermally conductive aluminum layer between the first and second iron layers, the low density of aluminum is utilized to partially replace the iron-based material, directly reducing the overall weight of the pot body and easing the user's frying burden. At the same time, the first nitride layer formed on the inside surface of the pot by nitriding significantly improves corrosion resistance from acidic ingredients and prevents food contamination due to the leaching of iron ions. The hollow cast steel body and the weight-reducing design with holes in the mounting parts maintain the strength of the handle while further reducing the overall weight.

[Figure 3] FIG. 2 is a plan view of the pot of the present invention. [Figure 4] FIG. 2 is a cross-sectional view of the pot of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the drawings.

[0017] Referring to Figs. 1 to 4, a pot body structure of a pot is shown. The pot includes a pot body 1, which is a cavity, the inside of which is used to store and cook food, and the outside of which is in direct contact with a heat source.

[0018] Thus, the pot body 1 comprises an inner surface for contacting food and an outer surface for contacting a heat source, wherein the pot body 1 comprises a ferrous layer 2, a ferric layer 3 and an aluminum layer 4.

[0019] The first iron layer 2 is disposed toward the inner surface of the pot body 1, i.e., the first iron layer 2 is disposed toward the inner cavity side of the pot body 1, and the second iron layer 3 is disposed toward the outer surface of the pot body. At the same time, an aluminum layer 4 for heat conduction is sandwiched between the first iron layer 2 and the second iron layer 3. The base material of the aluminum layer 4 is aluminum, which has good ductility, so the aluminum can be disposed in close contact with the first iron layer 2 and the second iron layer 3, and fits to the outside of the first iron layer 2 and the inside of the second iron layer 3 to form the pot body 1.

[0020] At the same time, because aluminum has a lower density than iron, the weight of the same volume of aluminum is less than that of iron, thereby reducing the weight of the pot body 1. Therefore, the thickness of the aluminum layer 4 is at least 2 / 5 of the thickness of the pot body 1, achieving a reasonable weight reduction. Furthermore, the inner surface of the pot body 1, i.e., the first iron layer 2, is coated with a first nitride layer 5 formed by nitriding treatment.

[0021] The side wall of the pot body 1 is connected to the handle 8 via a connecting piece 7, and the connecting piece 7 is a flat-head iron rivet that penetrates the side wall of the pot body 1 and the mounting hole in the handle 8.

[0022] The handle 8 includes a cast steel tube 9, both ends of which are connected to a first mounting member 10 and a second mounting member 11. The first mounting member 10 is a molded T-shaped member with a hole 12 on it to reduce weight but without affecting strength; the second mounting member 11 is a molded columnar member with a hole 12 on it, which can be used for hanging or storage.

[0023] The above embodiments are merely for illustrating the technical solutions of the present invention, and are not intended to limit the same; although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications may still be made to the technical solutions described in the above embodiments, or equivalent substitutions may be made for some of the technical features therein; however, such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
