Description

Technical Field

[0001] The present application relates to the technical field of kitchen tools, and in particular to a cooking utensil. Background Art

[0002] In existing cooking utensils, a multi-layer metal material composite (for example, a three-layer composite structure, etc.) is used to form the utensil base, which can overcome the shortcomings of a single metal material such as thermal conductivity, hardness, corrosion resistance, electromagnetic induction performance, etc., and improve the overall performance of the cooking utensils, and is therefore widely used.

[0003] The edge of the mouth of the cooking utensil is generally formed by cutting. After cutting, the material of the middle layer is exposed. Since the material of the middle layer generally has poor corrosion resistance, the edge of the mouth of the cooking utensil is very prone to oxidation and discoloration, affecting the appearance performance and hygiene and safety performance of the cooking utensil.

[0009] Optionally, a mounting groove is provided at the edge of the mouth, and the mounting groove is recessed in the edge of the mouth, and at least a portion of the sealing ring is embedded in the mounting groove, which can not only reduce the installation resistance of the sealing ring, making the installation of the sealing ring more convenient and labor-saving, but also increase the matching area between the vessel base and the sealing ring, thereby increasing the reliability of the connection of the sealing ring.

[0010] Optionally, the mounting groove forms a closing structure at least at the groove opening, thereby serving as a stopper for the sealing ring at the groove opening, clamping the sealing ring in the mounting groove to prevent the sealing ring from falling off from the mounting groove.

[0011] Optionally, the mounting groove is formed by removing the middle layer at the edge of the mouth, which can effectively prevent the middle layer from being exposed and retain the original structure of the vessel base as much as possible, thereby reducing production costs.

[0012] Optionally, the outer surface of the sealing ring and the inner surface of the mounting groove fit together, which can not only increase the matching area between the sealing ring and the mounting groove and increase the reliability of the sealing ring connection, but also form a sealed edge structure to prevent the internal intermediate layer from being damaged by corrosion.

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0037] like Figure 1-Figure 5 As shown, an embodiment of the present application provides a cooking utensil, which includes a vessel base 1, which is configured to have a cavity-like structure with an opening to facilitate the accommodating of food; the vessel base 1 includes an outer layer 11, an intermediate layer 12 and an inner layer 13 that are stacked, that is, the vessel base 1 is formed by processing a composite plate material including at least three layers of material, and the cutting edge of the composite plate forms an edge 1a of the opening of the vessel base 1; a sealing ring 2 is embedded in the edge 1a of the opening of the vessel base 1 to prevent the intermediate layer 12 from being exposed, that is, the sealing ring 2 is made of a material that is not easily oxidized and discolored, and the sealing ring 2 isolates and protects the intermediate layer 12, thereby preventing the edge 1a of the opening of the cooking utensil from oxidative discoloration, thereby improving the appearance performance and hygienic safety performance of the cooking utensil.

[0038] The cooking utensil provided in the embodiment of the present application can be used as the inner pot of a pressure cooker, or can be used in direct contact with a heat source; when the cooking utensil is used in direct contact with a heat source, a handle can be provided on the outer surface of the vessel base 1 to facilitate the user to lift the cooking utensil. Each layer of the vessel base 1 can be made of a single layer of material or a multi-layer composite material; for example, the outer layer 11 can be made of a single layer of material or a composite structure formed by multiple layers of material; the middle layer 12 can be made of a single layer of material or a composite structure formed by multiple layers of material; the inner layer 13 can be made of a single layer of material or a composite structure formed by multiple layers of material.

[0039] Further, the mouth of the vessel base 1 is provided with a flange structure folded outward, and the edge of the flange structure forms the mouth edge 1a of the vessel base 1, that is, the mouth edge 1a is located on one side of the vessel base 1 in the radial direction, and the structural strength of the vessel base 1 at the mouth is improved by providing the flange structure to prevent deformation and other damage to the mouth of the vessel base 1. It can be understood that the mouth of the vessel base 1 may not be provided with a flange structure, that is, the side wall of the vessel base 1 extends in the axial direction, and the mouth edge 1a is located at one end of the vessel base 1 in the axial direction.

[0040] Furthermore, the middle layer 12 is made of aluminum or aluminum alloy to reduce the weight of the vessel base 1, increase the thermal conductivity of the vessel base 1, and reduce the production cost; the sealing ring 2 is made of copper, copper alloy, titanium or titanium alloy. Since copper and titanium have high corrosion resistance and antibacterial effects, by making the sealing ring 2 of copper or titanium and arranging it on the mouth edge 1a of the vessel base 1 that contacts the food, the mouth edge 1a can be prevented from oxidative discoloration and the safety and hygiene performance of the cooking utensil can be improved.

[0041] Furthermore, the outer layer 11 and the inner layer 13 are both steel layers, and the vessel base 1 is a three-layer composite structure of steel-aluminum-steel. The steel layer has magnetic conductivity and is used as the contact material of the induction cooker. It has high corrosion resistance and will not react with food during the cooking process. It can also increase the structural strength of the vessel base 1. The aluminum layer can increase the thermal conductivity of the pot body. The three-layer composite structure of steel-aluminum-steel has the advantages of fast heat transfer, uniform heating, not easy to rust and corrosion, and high safety.

[0042] Furthermore, the mouth edge 1a of the vessel base 1 is provided with a mounting groove 1b, which is recessed in the mouth edge 1a of the vessel base 1, and at least a portion of the sealing ring 2 is embedded in the mounting groove 1b, which can reduce the installation resistance of the sealing ring 2, making the installation of the sealing ring 2 more convenient and labor-saving, and can increase the matching area between the vessel base 1 and the sealing ring 2, thereby increasing the reliability of the connection of the sealing ring 2. Specifically, the mounting groove 1b is set as an annular structure surrounding the mouth edge 1a of the vessel base 1, and the mounting groove 1b can be formed on the mouth edge 1a of the vessel base 1 by turning or the like, as long as a portion of the material of the mouth edge 1a of the vessel base 1 can be removed.

[0043] Further, the installation groove 1b is formed by removing the middle layer 12 of the mouth edge 1a of the vessel base 1, that is, only the middle layer 12 is removed from the mouth edge 1a of the vessel base 1, and the outer layer 11 and the inner layer 13 are kept intact, which can effectively prevent the middle layer 12 from being exposed, and can also retain the original structure of the vessel base 1 as much as possible, thereby reducing production costs. It can be understood that on the basis of removing the middle layer 12, a part of the outer layer 11 or the inner layer 13 adjacent to both sides can also be removed to ensure that there is no residual material of the middle layer 12 at the edge of the installation groove 1b.

[0044] Furthermore, the mounting groove 1b forms a closing structure at least at the groove opening, that is, along the direction pointing from the groove bottom to the groove opening, the width of the mounting groove 1b gradually decreases at least at the groove opening, thereby acting as a stopper for the sealing ring 2 at the groove opening, fixing the sealing ring 2 in the mounting groove 1b, and preventing the sealing ring 2 from falling off from the mounting groove 1b.

[0045] Furthermore, the notch of the installation groove 1b is formed into a closing structure by extrusion deformation, that is, before the sealing ring 2 is installed, the width of the installation groove 1b is substantially uniform, so as to reduce the difficulty of turning the installation groove 1b and ensure the labor-saving installation of the sealing ring 2. After the sealing ring 2 is installed in the installation groove 1b, the two sides of the installation groove 1b are pressed tightly, thereby forming a closing structure with a reduced notch, so as to prevent the sealing ring 2 from falling out after installation. It can be understood that the notch of the installation groove 1b can also be formed into a closing structure directly by removing material.

[0046] Furthermore, the outer surface of the sealing ring 2 and the inner surface of the mounting groove 1b are in contact with each other, which can increase the matching area between the sealing ring 2 and the mounting groove 1b and increase the reliability of the connection of the sealing ring 2, and can also form a sealed edge structure to prevent corrosion and other damage to the internal intermediate layer 12. It can be understood that a gap can also be left between the outer surface of the sealing ring 2 and the inner surface of the mounting groove 1b.

[0047] Furthermore, the bottom of the mounting groove 1b is configured as a concave arc surface, which can reduce stress concentration in the mounting groove 1b and make it easier for the sealing ring 2 and the mounting groove 1b to fit each other, thereby reducing the gap between the sealing ring 2 and the mounting groove 1b.

[0048] Furthermore, the sealing ring 2 is formed into a circular shape by bending a rod-shaped metal material, which can improve the compactness and uniformity of the sealing ring 2 and the matching degree between the sealing ring 2 and the mouth edge 1a of the vessel base 1; the cross section of the rod-shaped metal material can be set to a circular shape or an arc shape, or to any appropriate shape such as a rectangle, triangle or ring. It can be understood that the sealing ring 2 can also be formed by any appropriate method such as filling or casting.

[0049] Furthermore, the two ends of the rod-shaped metal material are welded to each other to form a closed circular structure, which increases the structural strength of the sealing ring 2 and prevents the sealing ring 2 from being deformed or loosened. The connection method is simple and reliable, and the sealing ring 2 can maintain a high uniformity as a whole. It can be understood that the two ends of the rod-shaped metal material can also be connected to each other using a threaded structure or a buckle structure.

[0050] Furthermore, at the mouth edge 1a of the vessel base 1, the end face of the outer layer 11 is smoothly connected to the sealing ring 2, and the end face of the inner layer 13 is smoothly connected to the sealing ring 2. The end face of the outer layer 11, the sealing ring 2 and the end face of the inner layer 13 form a convex arc surface 1c to avoid structural mutations on both sides of the sealing ring 2, which can prevent the sealing ring 2 from being worn or falling off under the action of external force, and improve the integrity and appearance of the cooking utensil. Among them, the convex arc surface 1c can be directly formed by the mutual matching of the end face of the outer layer 11, the sealing ring 2 and the end face of the inner layer 13, or can be formed by removing materials or extrusion deformation.

[0051] A processing method of the cooking utensil provided in the embodiment of the present application can be referred to as follows:

[0052] Step S1, punching and blanking the steel-aluminum-steel three-layer composite material into a circular sheet;

[0053] Step S2: Stretch the circular sheet to form a vessel base 1 (refer to Figure 2 );

[0054] Step S3, cleaning and drying the vessel substrate 1;

[0055] Step S4: Place the vessel base 1 in a lathe fixture, remove the aluminum layer of the mouth edge 1a by turning, and form a mounting groove 1b (refer to Figure 3 );

[0056] Step S5: Roll and press a rod-shaped metal material (copper rod or titanium rod) into the installation groove 1b to form an annular sealing ring 2 (refer to Figure 4 );

[0057] Step S6: Use rollers to press the two sides of the installation groove 1b tightly, so that the steel layers on both sides of the installation groove 1b press the sealing ring 2 (reference Figure 5 );

[0058] Step S7: sand and polish the mouth edge 1a of the vessel base 1 to form a convex arc surface 1c (refer to Figure 5 ).

[0059] Wherein, step S5 may further include welding two ends of the rod-shaped metal material to each other so that the sealing ring 2 forms a closed ring structure.

For those skilled in the art, the present application may have various modifications and variations. 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.
