Description

Technical Field

[0001] The utility model shows an inner pot and a cooking utensil, belonging to the technical field of cooking utensil. Background Art

[0002] Cooking utensils are common household appliances in daily life. They usually include a pot body and a pot lid. The pot body is provided with an inner pot and a heating device. The inner pot is generally made of metal. When the heating device is powered on, heat can be transferred to the inner pot, so that the food in the inner pot can be heated and cooked.

[0003] In the prior art, a folding process is usually used for inner liner with thin wall thickness, so that the flange of the inner liner has a larger thickness, thereby improving the texture of the inner liner, and at the same time it can also enhance the strength of the flange, improve the deformation resistance of the flange, and significantly improve the service life of the inner liner; and the inner liner usually uses a three-layer composite sheet, such as steel-aluminum-steel, steel-steel, etc. The three-layer composite sheet has higher food and health safety and better texture, but in the folding process, due to the difference in elongation rate between different materials, the edge material of the flange will be delaminated after the folding process, thereby reducing the aesthetics of the inner liner; in addition, after the folding process, the middle layer material will be directly exposed to the outside world, so that the middle layer material is prone to corrosion and rust, etc., affecting the service life of the inner liner. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the inner pot is prone to corrosion and rust after the folding process, which will also reduce the aesthetics of the inner pot. For this purpose, an inner pot and a cooking utensil are provided, which can effectively prevent the end of the flange from being directly exposed to the outside world, reduce the possibility of corrosion and rust at the end of the flange, and also improve the aesthetics of the inner pot.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An inner liner comprises an inner liner body, the inner liner body comprises a side wall and a flange arranged at the top end of the side wall and bent outward, a neck for transition is provided between the side wall and the flange, the flange comprises a first flange, the outer end of the first flange is bent inward from the lower side to form a second flange, a sealing ring is provided on the outer side of the neck, and the sealing ring is provided with a groove for the end of the second flange to extend into.

[0007] The beneficial effects of adopting the utility model are:

[0008] The groove of the edge sealing ring described in the utility model can allow the end of the second flange to extend into, and then the end of the second flange can be wrapped, effectively avoiding the end of the second flange from being directly exposed to the outside world, reducing the possibility of corrosion and rusting of the end of the second flange due to external influences, and thus significantly improving the service life of the second flange; in addition, the cooperation between the second flange and the edge sealing ring can make the overall feel of the flange more complete, which can effectively increase the aesthetics of the flange and make the liner more popular; secondly, the second flange is formed by bending the outer end of the first flange inward from the bottom, and the second flange and the first flange are superimposed on each other, so as to increase the overall thickness of the outer end of the flange, which helps to improve the texture and strength of the flange, and can significantly improve the deformation resistance of the outermost end of the flange, so that the liner has a longer service life; furthermore, the second flange is located on the lower side of the first flange, which can keep the top surface of the flange flat, which helps to improve the aesthetics of the liner.

[0009] Preferably, the height of the groove is less than the thickness of the second flange, and the second flange forms an interference fit with the groove. With the above technical solution, when the second flange is inserted into the groove, a compressive force is generated between the second flange and the inner wall of the groove, thereby making the inner wall of the groove and the second flange closely fit, which can effectively eliminate the gap between the inner wall of the groove and the second flange, so that the groove and the second flange form a sealed fit, and the end of the second flange can be isolated from the outside world through the interference fit between the sealing ring and the second flange, thereby effectively avoiding direct contact between the end of the second flange and the outside air, reducing the possibility of corrosion and rust at the end of the second flange, and thus significantly improving the service life of the second flange.

[0010] Preferably, the edge seal ring includes an upper edge seal, a lower edge seal and a fixing portion for connecting the upper edge seal and the lower edge seal, the fixing portion is installed on the outside of the neck, the upper edge seal is in contact with the bottom surface of the first flange, and a groove is formed between the upper edge seal and the lower edge seal. With the above technical solution, the first flange can support the upper edge seal, thereby limiting the deformation degree of the upper edge seal, effectively avoiding the increase of the groove height due to excessive deformation of the upper edge seal, keeping the spacing between the upper edge seal and the lower edge seal at a certain spacing, ensuring that the lower edge seal can maintain a sealed fit with the second flange, and improving the sealing of the edge seal ring to the second flange; in addition, the first flange and the second flange are installed on the outside of the neck through the fixing portion, which can reduce the difficulty of installing the edge seal ring, and at the same time, the fixing portion can also enhance the overall strength of the edge seal ring, making the fit between the second flange and the edge seal ring more stable and reliable.

[0011] Preferably, the thickness of the upper edge seal is smaller than that of the lower edge seal. With the aforementioned technical solution, when the second flange is inserted into the groove, both the upper and lower edge seals will be deformed. Since the lower edge seal is located at the lower side of the second flange and is directly exposed to the outside world, when the thickness of the lower edge seal is large, the influence of the deformation on the overall appearance of the lower edge seal can be reduced, and the flatness of the appearance of the lower edge seal can be maintained, which is beneficial to improving the aesthetics; while the upper edge seal is hidden between the second flange and the first flange and cannot be directly observed, so the deformation of the upper edge seal will not affect the overall aesthetics of the edge seal ring. In addition, reducing the thickness of the upper edge seal can save material consumption and reduce production costs. At the same time, it can also reduce the distance between the first flange and the second flange, so that the first flange and the second flange are kept as close as possible, thereby improving the strength of the outer end of the flange and making the outer end of the flange have a stronger ability to resist deformation.

[0012] Preferably, the edge seal ring includes a lower edge seal and a fixing portion for connecting the lower edge seal, the fixing portion is installed on the outer side of the neck, and a groove is formed between the lower edge seal and the first flange. By adopting the above technical solution, the production of the upper edge seal can be omitted, thereby significantly saving the production materials of the edge seal ring and reducing the production cost of the edge seal ring.

[0013] Preferably, the top surface of the second flange is in contact with the bottom surface of the first flange. By adopting the above technical solution, after omitting the upper edge sealing, the second flange can be closely attached to the first flange, so that the first flange and the second flange form mutual support, and when subjected to external pressure or impact, the pressure can be better dispersed and withstood, thereby significantly improving the overall strength of the flange and making the outer end of the flange have stronger anti-deformation ability.

[0014] Preferably, the flange further includes a bending portion, which is located between the first flange and the second flange, the outer end of the first flange is bent downward to form the bending portion, and the bottom end of the bending portion is bent inward to form the second flange. With the above technical solution, the bending portion serves as a transition portion between the first flange and the second flange, which can make the second flange extend more smoothly to the lower side of the first flange, and is conducive to reducing the gap between the first flange and the second flange, so that the flange as a whole maintains a high strength; in addition, the bending portion can also slow down the degree of bending of the flange, thereby reducing the possibility of the flange breaking, so that the flange maintains the proper strength and improves the service life of the flange.

[0015] Preferably, the connection between the top surface of the first flange and the bent portion is a smooth surface; and / or the connection between the bottom surface of the second flange and the bent portion is a smooth surface. With the above technical solution, the smooth surface can make the outer surface of the flange smoother, which helps to improve the aesthetics of the flange, and also can give users a better grip and enhance the user experience.

[0016] Preferably, the side wall includes an inner layer, a middle layer and an outer layer, the inner layer and the middle layer are longer than the outer layer, and the inner layer and the middle layer are bent inward from the lower side of the outer layer to form a second flange. With the above technical solution, during the flange stacking process, only the inner layer and the middle layer are stacked, while the outer edge is not stacked, which can effectively reduce the stress on the flange, reduce the possibility of cracking of the flange during the stacking process, and help to increase the service life of the flange.

[0017] The utility model also shows a cooking utensil, comprising a pot body, a pot cover and an inner pot, wherein the inner pot is an inner pot as described in any one of the above items, and the inner pot is placed in the pot body.

[0031] Embodiment 1:

[0032] like Figures 1 to 4 As shown, this embodiment shows an inner pot, including an inner pot body 1, the inner pot body 1 has a side wall 11, the inner pot body 1 forms an opening at the top end of the side wall 11, and food can be put into the inner pot body 1 through the opening, the top end of the side wall 11 is bent outward to form a flange 13, and a neck 12 for transition is provided between the side wall 11 and the flange 13, and the flange 13 includes a first flange 131, and the outer end of the first flange 131 is bent inward from the lower side to form a second flange 132, and a sealing ring 2 is provided on the outer side of the neck 12, and the sealing ring 2 is provided with a groove 24 for the end of the second flange 132 to extend into.

[0033] The groove 24 of the edge sealing ring 2 in this embodiment can allow the end of the second flange 132 to extend into, so as to wrap the end of the second flange 132, effectively avoiding the end of the second flange 132 from being directly exposed to the outside world, reducing the possibility of corrosion and rust at the end of the second flange 132 due to external influences, and thus significantly improving the service life of the second flange 132; in addition, the second flange 132 cooperates with the edge sealing ring 2 to make the overall feel of the flange 13 more complete, effectively increase the aesthetics of the flange 13, and make the interior The liner is more popular; secondly, the second flange 132 is formed by bending the outer end of the first flange 131 from the lower side inward, and the second flange 132 and the first flange 131 are superimposed on each other, thereby increasing the overall thickness of the outer end of the flange 13, helping to improve the texture and strength of the flange 13, and significantly improving the deformation resistance of the outermost end of the flange 13, so that the liner has a longer service life; furthermore, the second flange 132 is located on the lower side of the first flange 131, which can keep the top end surface of the flange 13 smooth, helping to improve the aesthetics of the liner.

[0034] like Figure 2 As shown, the edge sealing ring 2 in this embodiment is annular as a whole, and is fixed to the outer peripheral side of the neck 12, and includes a fixing portion 23, an upper edge sealing 21 and a lower edge sealing 22, wherein the fixing portion 23 is fixedly connected to the outer side of the neck 12, one end of the upper edge sealing 21 and the lower edge sealing 22 are connected to the fixing portion 23, and the other end extends radially outward along the inner container body 1, the upper edge sealing 21 is located on the upper side of the lower edge sealing 22 and is in contact with the bottom surface of the first flange 131, and a first flange 131 is formed between the upper edge sealing 21 and the lower edge sealing 22. The first flange 131 can support the upper edge seal 21 and limit the upward deformation of the upper edge seal 21, which can effectively prevent the upper edge seal 21 from increasing the height of the groove 24 due to excessive upward deformation. The first flange 131 can limit the spacing between the upper edge seal 21 and the lower edge seal 22 to a certain spacing, ensuring that the lower edge seal 22 can maintain a sealing fit with the second flange 132, thereby improving the sealing performance of the edge seal ring 2 to the second flange 132. It should also be noted that the edge seal ring 2 in this embodiment adopts an annular silicone ring, and the edge seal ring 2 has elasticity as a whole, so that the second flange 132 can form a sealing fit with the edge seal ring 2. In addition, the upper edge seal 21, the lower edge seal 22 and the fixing portion 23 are an integrated structure, which can improve the overall strength of the edge seal ring 2, reduce the possibility of the edge seal ring 2 breaking, and also reduce the difficulty and cost of manufacturing the edge seal ring 2.

[0035] like Figure 2As shown, the height of the groove 24 described in this embodiment is less than the thickness of the second flange 132. When the second flange 132 extends into the groove 24, a compression force is generated between the second flange 132 and the inner wall of the groove 24, so that the inner wall of the groove 24 and the second flange 132 are kept in close contact and form an interference fit. The interference fit can effectively eliminate the gap between the inner wall of the groove 24 and the second flange 132, so that the groove 24 and the second flange 132 form a sealed fit. The interference fit between the sealing ring 2 and the second flange 132 can isolate the end of the second flange 132 from the outside world, thereby effectively avoiding direct contact between the end of the second flange 132 and the outside air, reducing the possibility of corrosion and rust at the end of the second flange 132, and thus significantly improving the service life of the second flange 132.

[0036] In addition, the thickness of the upper edge seal 21 in this embodiment is smaller than that of the lower edge seal 22. When the second flange 132 forms an interference fit with the groove 24, the upper edge seal 21 and the lower edge seal 22 will both be deformed. Since the upper edge seal 21 is located between the first flange 131 and the second flange 132, and the lower edge seal 22 is located at the lower side of the second flange 132 and covers the second flange 132, the upper edge seal 21 is wrapped between the first flange 131 and the second flange 132 and is not directly exposed to the outside world and cannot be directly observed, while the lower edge seal 22 is exposed at the lower side of the second flange 132 and is in an observable state. In the field of vision, when the thickness of the lower edge seal 22 is large, the deformation of the lower edge seal 22 has little effect on the overall appearance of the lower edge seal 22, so that the lower surface of the lower edge seal 22 can still remain flat, thereby improving the aesthetics of the lower edge seal 22. In addition, increasing the thickness of the lower edge seal 22 can improve the protection ability of the lower edge seal 22 to the second flange 132, reduce the possibility of the second flange 132 being damaged by external force, which is beneficial to improving the service life of the second flange 132. At the same time, the thicker lower edge seal 22 has a more stable overall structure and is not easy to be damaged, which can also improve the service life of the lower edge seal 22.

[0037] Correspondingly, in this embodiment, since the upper edge seal 21 cannot be directly observed from the outside, the deformation of the upper edge seal 21 will not affect the overall aesthetics of the edge seal ring 2. When the thickness of the upper edge seal 21 is relatively small, after the second flange 132 is inserted into the groove 24 and the flattening process is completed, the first flange 131 and the second flange 132 will squeeze the upper edge seal 21, further reducing the thickness of the upper edge seal 21, and thus reducing the distance between the first flange 131 and the second flange 132, so that the first flange 131 and the second flange 132 can be kept as close as possible, thereby improving the strength of the outer end of the flange 13, and making the outer end of the flange 13 have a stronger ability to resist deformation. At the same time, the upper edge seal 21 with a smaller thickness can save the manufacturing material of the upper edge seal 21 and reduce the manufacturing cost of the upper edge seal 21.

[0038] like Figure 2 As shown, one end of the flange 13 described in this embodiment is connected to the neck 12 and extends radially outward from the inner liner body 1 to form a first flange 131. The outer end of the first flange 131 is bent downward to form a bending portion 133. The bottom end of the bending portion 133 is bent inward to form a second flange 132. The bending portion 133 serves as a transition portion between the first flange 131 and the second flange 132, which can make the second flange 132 extend more smoothly to the lower side of the first flange 131, and is conducive to reducing the gap between the first flange 131 and the second flange 132, so that the flange 13 maintains a higher strength as a whole; in addition, the bending portion 133 can also slow down the degree of bending of the flange 13, thereby reducing the possibility of breakage of the flange 13, so that the flange 13 maintains its due strength, and improves the service life of the flange 13.

[0039] In order to improve the lifting feel of the flange 13, in this embodiment, the connection between the top surface of the first flange 131 and the bending portion 133 is a smooth surface, the connection between the bottom surface of the second flange 132 and the bending portion 133 is a smooth surface, and the side of the bending portion 133 away from the inner liner body 1 is a smooth surface. The smooth surface can make the outer surface of the flange 13 smoother, which helps to improve the aesthetics of the flange 13, and also can give the user a better lifting feel, which can enhance the user's experience; of course, it can be understood that in other embodiments, the smooth surface can be only provided at the connection between the top surface of the first flange 131 and the bending portion 133; or the smooth surface is only provided at the connection between the bottom surface of the second flange 132 and the bending portion 133; or the smooth surface is only provided on the side of the bending portion 133 away from the inner liner body 1.

[0040] like Figure 3 As shown, the side wall 11 in this embodiment is made of a three-layer composite sheet. The side wall 11 includes an inner layer 111, a middle layer 112 and an outer layer 113 from the inside to the outside. The top of the side wall 11 is bent outward to form a flange 13. Before the flange 13 is stacked, the outer layer 113 is first turned to make the length of the inner layer 111 and the middle layer 112 greater than the outer layer 113. During the stacking process, the inner layer 111 and the middle layer 112 are bent to make the inner layer 111 and the middle layer 112 folded. It is bent and extends to the lower side of the outer layer 113, thereby forming the second flange 132, that is, in this embodiment, the first flange 131 has the inner layer 111, the middle layer 112 and the outer layer 113 from top to bottom, and the second flange 132 has the middle layer 112 and the inner layer 111 from top to bottom; when the outer layer 113 is not bent, the stress on the flange 13 can be effectively reduced, and the possibility of cracking of the flange 13 during the folding process can be reduced, which helps to increase the service life of the flange 13.

[0041] It should be noted that the three-layer composite sheet described in this embodiment can be steel-aluminum-steel or iron-steel, that is, the inner layer 111 is a stainless steel layer, the middle layer 112 is an aluminum layer, and the outer layer 113 is a stainless steel layer; or the inner layer 111 is a stainless steel layer, the middle layer 112 is an iron layer, and the outer layer 113 is a stainless steel layer. Since the elongation rate of the inner layer 111 material is different from that of the middle layer 112 material, after folding, the end of the middle layer 112 material will protrude from the inner layer 111 material and then be directly exposed to the outside world. In addition, the aluminum layer or the iron layer is more susceptible to corrosion by water and air, so the middle layer 112 is more prone to corrosion and rust. The end of the inner layer 111 and the middle layer 112 is wrapped in the groove 24 by the edge sealing ring 2 to isolate the middle layer 112 from the external water and air, which can prevent the middle layer 112 from being directly exposed to the outside world, thereby reducing the possibility of corrosion and rust in the middle layer 112, which helps to increase the service life of the second flange 132.

[0042] like Figure 4 As shown, after the flange 13 is bent, the flange 13 is subjected to a beveling process. During the beveling process, the flange 13 is gradually bent and extended toward the inner liner body 1 to form a second flange 132. At the same time, the lower sealing edge 22 is deformed downward by external force to increase the height of the groove 24 so that the second flange 132 can extend into the groove 24. After completion, the lower sealing edge 22 forms a sealing fit with the second flange 132; thereafter, the second flange 132 is flattened to keep the second flange 132 flat as a whole, reduce the gap between the second flange 132 and the first flange 131, and keep the upper sealing edge 21 and the upper surface of the second flange 132 in close contact, and the lower sealing edge 22 and the lower surface of the second flange 132 in close contact, thereby improving the sealing performance between the sealing ring 2 and the second flange 132.

[0043] Embodiment 2:

[0044] like Figure 5 and Figure 6As shown, the main difference between this embodiment and the first embodiment is that the edge sealing ring 2 described in this embodiment includes a lower edge sealing 22 and a fixing portion 23 for connecting the lower edge sealing 22, the fixing portion 23 is installed on the outer side of the neck 12, and a groove 24 is formed between the lower edge sealing 22 and the first flange 131. When the second flange 132 extends into the groove 24 and completes the flattening process, the top surface of the second flange 132 is in contact with the bottom surface of the first flange 131. In this embodiment, the edge sealing ring 2 omits the upper edge sealing 21, and the production of the upper edge sealing 21 can be omitted, thereby significantly saving the production materials of the edge sealing ring 2 and reducing the production cost of the edge sealing ring 2; in addition, after omitting the upper edge sealing 21, the second flange 132 can maintain a close fit with the first flange 131, so that the first flange 131 and the second flange 132 form mutual support, and when subjected to external pressure or impact, they can better disperse and withstand pressure, thereby significantly improving the overall strength of the flange 13, so that the outer end of the flange 13 has a stronger ability to resist deformation.

[0045] The other structures of this embodiment are the same as those of the first embodiment, and will not be described in detail here.
