Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchenware, specifically to a pot body and a pressure cooker including the pot body. Background Technology
[0002] Pressure cookers are popular among consumers because they are energy-saving, time-saving, and have multiple cooking functions. Pressure cookers utilize the physical phenomenon that the boiling point of a liquid increases under higher pressure. By applying pressure to water, the water can reach a higher temperature without boiling, thus speeding up the cooking process. When cooking food in a pressure cooker, ingredients can be heated to over 100°C. In high-altitude areas, pressure cookers can avoid the problem of water boiling point dropping and food not cooking properly.
[0003] To improve the efficiency of pressure cookers, save cooking time, reduce weight, and lower transportation costs, pressure cookers need to be designed with the thinnest possible body while still meeting national standards for pressure cooker thickness. However, the edges of the pot are typically formed by flanging the upper part of the pot. Since the edges are subject to greater stress and need to be sealed with the lid, a thinner pot body may not meet the strength requirements.
[0004] Therefore, how to provide a pot body structure that can reduce thickness while still meeting strength requirements has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0014] As an optional embodiment of this utility model, the folded edge extends around the axis of the pot cylinder and is connected to the edge of the bent edge on the side opposite to the axis of the pot cylinder.
[0015] As an optional embodiment of this utility model, the top of the inner edge of the reinforcing ring has a transition arc surface, and the main structure also includes a bending part, which is connected between the flange and the top opening of the pot cylinder. The diameter of the bending part gradually increases in the direction away from the bottom of the pot, and the surface of the bending part facing the bottom of the pot is in contact with the transition arc surface.
[0016] As an optional embodiment of this utility model, the main structure is made of metal.

[0019] As an optional embodiment of this utility model, the thickness of the bent portion is 0.6mm-0.8mm.
[0020] As a second aspect of this utility model, a pressure cooker is provided, the pressure cooker including a lid and a pot body provided in the embodiment of this utility model, the lid including a cover body and a locking structure connected to each other, the cover body being used to close the top opening of the pot, and the locking structure being used to contact the surface of the reinforcing ring and the folded portion facing the bottom of the pot to maintain the relative position of the lid and the pot body.

At this time, the flanged part is mainly subjected to the tensile stress generated by the folded part and the covering part being pulled upward along with the reinforcing ring. Therefore, compared with the case where the outer flange of the pot in the existing pressure cooker is subjected to an upward bending moment, the requirement for the thickness of the main structure material in this utility model design can be lower.
[0024] In the pot body provided by this utility model, the flange (i.e., flange part, covering part and folded part) of the main structure is turned outward to cover the reinforcing ring. The upward force of the reinforcing ring on the pot lid can be converted into tensile stress on the main structural material. This can reduce the thickness of the main structural material while ensuring the structural strength of the pot body. In this way, the pressure cooker can improve working efficiency, save cooking time, reduce the weight of the pressure cooker, save material costs and transportation costs, and ensure the safety of the pressure cooker.

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.
[0038] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.
[0039] Existing pressure cooker structures are generally divided into two types: clamp-type pressure cookers and screw-on pressure cookers. Clamp-type pressure cookers use a mechanical clamp structure on the lid that works in conjunction with a flange structure on the edge of the pot body to lock the lid and pot body together, forming a sealed state inside the pot. The flange structure on the edge of the pot body needs to have a certain thickness to withstand the increased pressure inside the pot. Screw-on pressure cookers, on the other hand, have several teeth distributed on the pot body and lid. By rotating the lid, the teeth on the pot body overlap with the teeth on the lid to achieve locking between the pot body and the lid.
[0040] However, whether it is the flange on the edge of the pot in the clamp-type pressure cooker structure or the teeth formed by the flange on the edge of the pot in the screw-on pressure cooker structure, they all need to be designed to have a large thickness, so as to prevent the lid from flipping up due to excessive torque when the pressure inside the pot is too high, causing the lid to fly off the pot and affecting the safety of the pressure cooker.
[0041] To address the aforementioned technical problems, as one aspect of this utility model, a pot body is provided, such as... Figure 2 , Figure 6 , Figure 7 , Figure 9 As shown, the pot body includes a main structure 100 and a reinforcing ring 200, as... Figures 1 to 4 , Figures 6 to 9 As shown, the main structure 100 includes a pot cylinder 110, a pot bottom 120, a flanged portion 130, a covering portion 140, and a folded portion 150. The pot bottom 120 closes the bottom opening of the pot cylinder 110. The flanged portion 130 is connected to the outside of the top opening of the pot cylinder 110 (in this utility model, the outside refers to the side of each component away from the axis of the pot body). The reinforcing ring 200 is sleeved on the pot cylinder 110 and is located on the side of the flanged portion 130 facing the pot bottom 120. The folded portion 150 is located on the side of the reinforcing ring 200 facing the pot bottom 120. The covering portion 140 surrounds the outside of the reinforcing ring 200 in the circumferential direction and is connected between the flanged portion 130 and the folded portion 150.
[0042] The pot body provided by this utility model has a multi-part structure, which includes a main structure 100 and a reinforcing ring 200. The main structure 100 includes a pot drum 110 for holding food and a pot bottom 120, and also includes a flanged part 130, a covering part 140 and a folded part 150 for fixing the reinforcing ring 200. The flanged part 130, the covering part 140 and the folded part 150 are flipped outward in sequence and cover the top surface, outer side surface and bottom surface of the reinforcing ring 200. So when the food in the pot heats up and the pressure in the pot increases, the reinforcing ring 200 is subjected to the upward force of the pot lid. At this time, the flanged part 130 is mainly subjected to the tensile stress generated by the folded part 150 and the covering part 140 being pulled upward together with the reinforcing ring 200. Therefore, compared with the case where the outer flange of the pot in the existing pressure cooker is subjected to the upward bending moment, the material thickness requirement of the main structure 100 in this utility model design can be lower.
[0043] In the pot body provided by this utility model, the flange (i.e., flange portion 130, covering portion 140 and folded portion 150) of the main structure 100 is turned outward to cover the reinforcing ring 200. The upward force of the reinforcing ring 200 under the lid can be converted into tensile stress on the material of the main structure 100. This can reduce the thickness of the material of the main structure 100 while ensuring the structural strength of the pot body. In this way, the working efficiency of the pressure cooker is improved, cooking time is saved, the weight of the pressure cooker is reduced, material costs and transportation costs are saved, while ensuring the safety of the pressure cooker.
[0044] As an optional embodiment of this utility model, the main structure 100 is made of metal.
[0045] To ensure the structural strength of the pot body opening edge, such as Figure 6 , Figure 7 As shown, the reinforcing ring 200 fills the space defined by the flange portion 130 and the folded portion 150. That is, the reinforcing ring 200 is a solid structure and fills the space defined by the pot drum 110, the flange portion 130, the covering portion 140 and the folded portion 150.
[0046] As an optional embodiment of this utility model, the pot drum 110, pot bottom 120, flanged part 130, covering part 140 and folded part 150 are formed as one piece, that is, the main structure 100 is integrally formed from metal material through processes such as extrusion.
[0047] In one optional embodiment of this utility model, the thickness of the main structure 100 is 0.6mm-0.8mm. That is, the thickness of the pot drum 110 is 0.6mm-0.8mm, the thickness of the pot bottom 120 is 0.6mm-0.8mm, the thickness of the flanged part 130 is 0.6mm-0.8mm, the thickness of the covering part 140 is 0.6mm-0.8mm, and the thickness of the folded part 150 is 0.6mm-0.8mm.
[0048] As an optional embodiment of this utility model, the pot body provided by this utility model can be a clamp-type pot body, specifically, as shown in the example below. Figure 8 , Figure 9 As shown, the flanged portion 130, the covering portion 140, and the folded portion 150 all extend around the axis of the pot cylinder 110, that is, the flanged portion 130, the covering portion 140, and the folded portion 150 all extend completely around the outer edge of the top opening of the pot body.
[0049] As an optional embodiment of this utility model, such as Figure 7 As shown, the flanged part 130 and the covering part 140 are connected by an arc surface, thereby reducing the sharp edges of the pot body surface and improving the user experience.
[0050] As another optional embodiment of this utility model, the pot body provided by this utility model can also be a screw-on pot body, specifically, as shown in... Figure 5 As shown, the reinforcing ring 200 includes an annular portion 210 and a plurality of protrusions 220. The plurality of protrusions 220 are connected to the outer edge of the annular portion 210 and are distributed at intervals along the circumference. The shape of the flange portion 130 corresponds to the shape of the reinforcing ring 200.
[0051] Understandably, the protrusion 220 and the corresponding material of the main structure 100 together form teeth distributed around the outer periphery of the pot body, which are used to engage with teeth on the pot lid to achieve a locking connection.
[0052] As an optional embodiment of this utility model, such as Figure 5 As shown, the outer side of the protrusion 220 and the outer edge of the annular part 210 are connected by an arc-shaped transition to ensure the smoothness of the lid and the pot body when they are fastened together.
[0053] As an optional embodiment of this utility model, such as Figure 3 , Figure 4 As shown, the covering portion 140 includes a plurality of arc-shaped edges 141 and a plurality of bent edges 142 distributed circumferentially. The arc-shaped edges 141 are connected between the bent edges 142. The bent edges 142 cover the outer surface of the protrusion 220, and the arc-shaped edges 141 cover the outer surface of the annular portion 210.
[0054] The folded portion 150 includes a plurality of folded edges distributed circumferentially, and the plurality of folded edges are connected one-to-one with a plurality of bent edges 142, and the folded edges are located on the side of the protrusion 220 facing the bottom of the pot 120.
[0055] As an optional embodiment of this utility model, such as Figure 3 , Figure 4 As shown, the folded edge of the folded portion 150 extends around the axis of the pot drum 110 and is connected to the edge of the bent edge 142 on the side opposite to the axis of the pot drum 110.
[0056] As an optional embodiment of this utility model, such as Figures 5 to 7 As shown, the top of the inner edge of the reinforcing ring 200 has a transition arc surface a, and the main structure 100 also includes a bending part 160. The bending part 160 is connected between the flange part 130 and the top opening of the pot cylinder 110, and the diameter of the bending part 160 gradually increases in the direction away from the bottom of the pot 120. The surface of the bending part 160 facing the bottom of the pot 120 is in contact with the transition arc surface a.
[0057] As an optional embodiment of this utility model, the thickness of the bent portion 160 is 0.6mm-0.8mm.
[0058] As an optional embodiment of this utility model, the reinforcing ring 200 is made of a material with a certain strength, such as aluminum, iron or plastic.
[0059] As a second aspect of this utility model, a pressure cooker is provided. The pressure cooker includes a lid and a pot body provided in the embodiment of this utility model. The lid includes a cover body and a locking structure connected to each other. The cover body is used to close the top opening of the pot cylinder 110. The locking structure is used to contact the surface of the reinforcing ring 200 and the folded portion 150 facing the bottom of the pot 120 to maintain the relative position of the lid and the pot body.
[0060] In the pressure cooker provided by this utility model, the pot body has a multi-part structure, including a main structure 100 and a reinforcing ring 200. The main structure 100 includes a pot drum 110 for holding food and a pot bottom 120, and also includes a flanged part 130, a covering part 140 and a folded part 150 for fixing the reinforcing ring 200. The flanged part 130, the covering part 140 and the folded part 150 are flipped outward in sequence and cover the top surface, outer side surface and bottom surface of the reinforcing ring 200. So when the food in the pot heats up and the pressure in the pot increases, the reinforcing ring 200 is subjected to the upward force of the pot lid. At this time, the flanged part 130 is mainly subjected to the tensile stress generated by the folded part 150 and the covering part 140 being pulled upward along with the reinforcing ring 200. Therefore, compared with the case where the outer flange of the pot in the existing pressure cooker is subjected to an upward bending moment, the material thickness requirement of the main structure 100 in this utility model design can be lower.
[0061] In the pressure cooker provided by this utility model, the flange of the main body structure 100 is wrapped with a reinforcing ring 200. The upward force of the reinforcing ring 200 under the lid can be converted into tensile stress on the material of the main body structure 100. This can reduce the thickness of the material of the main body structure 100 while ensuring the strength of the pot body structure. In this way, the working efficiency of the pressure cooker is improved, cooking time is saved, the weight of the pressure cooker is reduced, material costs and transportation costs are saved, while ensuring the safety of the pressure cooker.
