Description

Technical Field

[0001] This invention relates to the field of cookware, and more specifically, to a deformation-resistant cookware. Background Technology

[0002] A pot is one of the most important tools in the kitchen. When using it, the pot is heated, and then food is poured into it and heated. The food is then stirred with a spatula to ensure it is fully heated, thus achieving the effect of stir-frying.

[0003] A search of existing technologies revealed an invention patent with publication number CN211242799U, which discloses a cookware comprising a pot body and a pot bottom. The inner surface of the pot bottom has a recessed oil dot, which is circular and includes multiple rings of different diameters arranged concentrically. Between adjacent rings, the inner edge of the larger ring and the outer edge of the smaller ring are circumferentially connected to form a connecting concave line. This cookware features a recessed oil dot at the bottom, allowing cooking oil to collect there, facilitating rapid heating of the oil located at the oil dot. The rings and raised structures at the oil dot counteract the deformation force during dry heating of the pot bottom, mitigating the deformation effect.

[0004] The aforementioned patent solves the problem of existing cookware easily deforming when dry-heating by setting a ring body to prevent the bottom of the pot from deforming. However, when frying eggs or cooking small ingredients, the bottom of the pot cannot be adjusted according to the size of the ingredients, resulting in some heat being wasted during heating.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] The purpose of this invention is to provide a deformation-resistant cookware to solve the above-mentioned problems, so that the bottom of the pot has the ability to resist deformation and the area of ​​the bottom of the pot can be adjusted according to the size of the food.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a deformation-resistant cookware, including a pot body, a heat collection groove provided on the bottom surface of the pot body, a plurality of concentric annular grooves provided on the inner wall of the heat collection groove, the inner diameter of the plurality of annular grooves gradually decreasing from the outside to the inside, a gap existing between two adjacent annular grooves, and a limiting ring detachably connected inside the annular groove.

[0008] By adopting the above technical solution and setting up a heat collection groove, the flame is located within the heat collection groove when the pot is heated, thus preventing heat loss when the flame heats the heat collection groove. At this time, the pot has a heat collection effect. This design effectively improves the heat energy utilization rate of the pot and makes the pot more convenient and quick to use. Furthermore, by setting up a limiting ring, the deformation resistance of the pot bottom is improved. The limiting ring is set in a ring shape, which can improve the deformation limiting effect, so that the bottom of the pot can maintain the flatness of the arc surface after heating, thereby effectively extending the service life of the pot and preventing the deformation of the bottom of the pot from affecting the normal use of the pot. Moreover, since the limiting ring is detachable, when the volume of the food being stir-fried is small, the number of limiting rings can be added or removed to adjust the heating area of ​​the bottom of the pot, further improving the practicality of the pot. This design has a simple structure, is easy to operate, and is easy to implement.

[0009] The present invention is further configured such that: the inner wall of the heat collection tank is a spherical arc surface, and a plane is provided on the bottom surface of the pot body, the plane is arranged in a ring shape, and the inner diameter of the plane is the same as the outer diameter of the heat collection tank.

[0010] By adopting the above technical solution, the spherical arc surface of the inner wall of the heat collection tank can cover the flame when heating the bottom of the pot, thus preventing heat loss and further improving the heat collection effect of the pot and the heat energy utilization rate of the pot. At the same time, the spherical arc surface increases the contact area between the bottom of the pot and the flame, thereby effectively increasing the heating speed of the pot and making the heating efficiency of the pot higher, thus improving the efficiency of the pot's use. Furthermore, by setting a flat surface, the pot can be placed on a table or stove when in use. At this time, the flat surface is in contact with the stove or table, so that the pot can be placed stably, further improving the practicality of the pot. It can also prevent the heat collection tank from directly contacting external objects, thus preventing heat transfer and heat loss, making the use of the pot more energy-saving and environmentally friendly. When the pot is placed on the table, the flat surface is in contact with the table, and a cavity is formed between the table and the heat collection tank. At the same time, the heat that has not been lost in the heat collection tank is located in the cavity, thus keeping the bottom of the pot warm and keeping the food in the pot warm, giving the pot a good heat preservation effect.

[0011] The present invention is further configured such that: a through groove for connecting several annular grooves is provided on the inner wall of the heat collection tank, and one end of the through groove extends to the outside of the heat collection tank.

[0012] By adopting the above technical solution and setting a through groove, the flame is located in the heat collection groove when the pot is in use. At this time, the heat collection groove covers the flame, and the flame burns away all the oxygen in the heat collection groove, resulting in a pressure difference between the inside and outside of the heat collection groove. At this time, the outside air enters the heat collection groove through the through groove due to the pressure difference, thus providing sufficient oxygen for the flame to burn continuously and preventing the flame from going out due to lack of oxygen when heating the pot. This design is not only simple in structure but also easy to operate, effectively improving the practical performance of the pot.

[0013] The invention is further configured such that: two oppositely arranged sliding grooves are provided on the inner sidewall of the annular groove, and sliders that can slide within the sliding grooves are fixedly connected to both sides of the limiting ring.

[0014] By adopting the above technical solution, and by setting a sliding groove and a slider, when it is necessary to adjust the heating area of ​​the pot bottom, the limiting ring can be rotated through the groove. At this time, the slider slides in the groove as the limiting ring rotates, until the slider slides to the groove. Further moving the limiting ring will separate the limiting ring from the annular groove. This design facilitates the installation and removal of the limiting ring. By removing and installing the limiting ring, the heating area of ​​the pot bottom can be increased or decreased, so that the heat received by the pot bottom can be adjusted according to the size of the food. This improves the practicality of the pot. Furthermore, when the limiting ring is separated from the annular groove, the heat collection groove is heated. The inner wall of the annular groove can absorb heat and transfer the heat to the food. Therefore, this design can increase the heating area, thereby improving the heat utilization rate of the pot.

[0015] The present invention is further configured such that: the slider has a rectangular cross-section, and the slider can abut against the inner wall of the groove.

[0016] By adopting the above technical solution, since the slider has a rectangular cross-section, when the slider is located in the groove, the slider abuts against the inner wall of the groove, thereby limiting the range of motion of the limiting ring. This prevents the limiting ring from separating from the annular groove due to gravity when the pot is in use, thus avoiding affecting the normal use of the pot. This design makes the pot more convenient and faster to use.

[0017] The present invention is further configured such that: a slot is provided on the inner wall of the slide groove, and a locking block is fixedly connected to the slider so as to engage with the slot.

[0018] By adopting the above technical solution, and by setting a locking block and a locking groove, when the slider slides to a certain position in the slide groove, the locking block can be locked into the locking groove on the inner wall of the slide groove. At this time, the limiting ring is fixed and thus achieves the function of fixing the limiting ring, avoiding affecting the normal use of the pot body, and preventing the limiting ring from rotating when the pot body is in use, so that the slider rotates to the through groove. At this time, the limiting ring separates from the annular groove due to gravity.

[0019] The present invention is further configured such that: the top surface of the annular groove is arc-shaped, and the top surface of the limiting ring is provided with an arc surface that can fit with the top surface of the annular groove.

[0020] By adopting the above technical solution and setting the arc surface, when the limiting ring is located in the annular groove, the arc surface increases the contact area between the limiting ring and the annular groove, thereby making the installation of the two more secure. Furthermore, when the limiting ring is separated from the annular groove, the arc-shaped inner top surface of the annular groove can increase the contact area between the flame and the bottom of the pot, thereby further improving the heat conduction effect of the bottom of the pot, making the pot more practical, and making it faster to stir-fry food.

[0021] The present invention is further configured such that an anti-deformation layer is fixedly connected to the plane.

[0022] By adopting the above technical solution and setting an anti-deformation layer, the flat surface can be prevented from deforming when the bottom of the pot is heated, thus affecting the normal placement of the pot. This design effectively improves the anti-deformation ability of the bottom of the pot, making the pot more convenient to use and further improving the practicality of the pot.

[0023] The present invention is further configured such that: both the anti-deformation layer and the confining ring are made of titanium-magnesium alloy, and the weight of several of the confining rings gradually decreases from the outside to the inside.

[0024] By adopting the above technical solution, the titanium-magnesium alloy, with its characteristics of hardness, resistance to deformation, strong metallic luster, high resistance to deformation, light weight, and good mechanical strength, provides a deformation-resistant layer and a lightweight retaining ring. This effectively improves the deformation resistance of the pot bottom, making the pot more convenient to use. Furthermore, the lightweight nature of the titanium-magnesium alloy prevents the improved pot from becoming too heavy, further enhancing its practicality. Since the weight of the retaining ring gradually decreases from the outside to the inside, the overall weight of the pot can be adjusted according to actual usage habits. This adjustment is achieved by rotating the retaining ring, which separates the slider from the groove, thus separating the retaining ring from the annular groove and adjusting the pot's weight. This allows the pot to suit the usage habits of different people, further improving its practicality.

[0025] In summary, the present invention has the following beneficial effects:

[0026] This invention, by setting a limiting ring, can restrict the shape of the pot bottom when it is heated, thereby preventing deformation of the pot bottom after heating. Furthermore, by setting a heat collection groove, heat can be concentrated in the heat collection groove, thereby improving the utilization rate of heat energy and making the pot more practical. When cooking small-volume ingredients, the number of limiting rings can be adjusted according to the size of the ingredients, thereby adjusting the heating area of ​​the pot bottom, so that the heat energy utilization rate can be adjusted according to the actual situation.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 2-4As shown, a deformation-resistant cookware includes a pot body 1. A heat-collecting groove 13 is provided on the bottom surface of the pot body 1. The inner wall of the heat-collecting groove 13 is a spherical arc surface. During manufacturing, the heat-collecting groove 13 can be pressed into shape using a stamping machine. When the pot body 1 is heated, the flame is located within the heat-collecting groove 13. Because the inner wall of the heat-collecting groove 13 is spherically arc-shaped, it can cover the flame, thus preventing heat loss and giving the pot body 1 a heat-collecting effect, improving the heat energy utilization rate of the pot body 1. Furthermore, the spherical arc surface increases the contact area between the bottom of the pot and the flame, thereby increasing the heating speed of the pot body 1, making the heating efficiency of the pot body 1 higher, and making the pot body 1 more convenient and quick to use. A flat surface 2 is provided on the bottom surface of the pot body 1, which can also be die-cast using a stamping machine. The flat surface 2 is annular, and the inner diameter of the flat surface 2 is the same as the outer diameter of the heat-collecting groove 13, so that the flat surface 2 fits snugly against the outer diameter of the heat-collecting groove 13. Therefore, when the pot body 1 is used, it is placed on a table or stovetop, and the flat surface 2 fits snugly against the stovetop or stovetop. The tabletop contact design ensures the pot body 1 is placed stably, further enhancing its practicality. It also prevents direct contact between the heat collection groove 13 and external objects, thus avoiding heat transfer and loss. When the pot body 1 is placed on the table, the flat surface 2 fits against it, closing the heat collection groove 13 and forming a cavity 6 between them. The heat that hasn't dissipated from the heat collection groove 13 is contained within the cavity 6, effectively insulating the bottom of the pot and maintaining the temperature of the food inside. This design further enhances the practicality of the pot body 1, providing excellent heat retention. Furthermore, the anti-deformation layer fixedly connected to the flat surface 2 prevents deformation of the flat surface 2 when heating the bottom, thus ensuring the pot body 1 remains stable and effectively improving its deformation resistance. This makes the pot body 1 more convenient to use and further enhances its practicality.

[0034] like Figures 1-4As shown, the inner wall of the heat collection tank 13 is provided with several concentric annular grooves 7. When manufacturing the annular grooves 7, the annular grooves 7 and the heat collection tank 13 can be die-cast together by a stamping machine after the pot body 1 is manufactured. The inner diameter of the annular grooves 7 gradually decreases from the outside to the inside. A limiting ring 4 is detachably connected inside the annular groove 7. This design allows multiple limiting rings 4 to be set on the bottom of the pot. When the bottom of the pot expands due to heat, the limiting ring 4 can limit the expansion range of the bottom of the pot, thereby preventing the bottom of the pot from deforming over a large area after heating and affecting the normal use of the pot body 1. This effectively improves the deformation resistance of the bottom of the pot. Furthermore, the annular arrangement of the limiting rings 4 can further improve the deformation limiting effect, so that the bottom of the pot can maintain the flatness of the arc surface 14 after heating. There is a gap 5 between two adjacent annular grooves 7, which makes the pot... When heated, heat can be transferred through gap 5 to heat food, making the pot body 1 more practical and convenient. The inner top surface of the annular groove 7 is arc-shaped. This arc-shaped top surface can be cast together with the annular groove 7 when it is stamped by the stamping machine, making the casting process simpler and more convenient. The top surface of the limiting ring 4 is provided with an arc surface 14 that can fit with the inner top surface of the annular groove 7. Therefore, when the limiting ring 4 is located in the annular groove 7, the arc surface 14 increases the contact area between the limiting ring 4 and the annular groove 7, making the installation of the two more secure. When the limiting ring 4 is separated from the annular groove 7, the arc-shaped inner top surface of the annular groove 7 can increase the contact area between the flame and the bottom of the pot, thereby further improving the heat conduction effect of the bottom of the pot, making the pot body 1 more practical and faster when stir-frying food.

[0035] like Figures 2-4 As shown, a through groove 3 for connecting several annular grooves 7 is provided on the inner wall of the heat collection tank 13. After the pot body 1 is cast, the through groove 3 can be punched out on the inner wall of the heat collection tank 13 by a grooving machine or other equipment. One end of the through groove 3 extends to the outside of the heat collection tank 13. There is a gap between the limiting ring 4 and the annular groove 7. Therefore, when the pot body 1 is in use, the flame is located inside the heat collection tank 13. At this time, the heat collection tank 13 covers the flame. The flame burns and consumes all the oxygen in the heat collection tank 13, resulting in a pressure difference between the inside and outside of the heat collection tank 13. At this time, the outside air enters the heat collection tank 13 through the through groove 3 due to the pressure difference, and provides oxygen to all directions of the flame through the gap between the annular groove 7 and the limiting ring 4, thereby achieving the effect of supplying oxygen for the flame to burn. This allows the flame to burn continuously and prevents the flame from going out due to lack of oxygen when heating the pot body 1. This design is not only simple in structure but also easy to operate, effectively improving the practical performance of the pot body 1.

[0036] like Figures 2-4As shown, two opposing sliding grooves 11 are provided on the inner wall of the annular groove 7. Sliding blocks 10, which can slide within the sliding grooves 11, are fixedly connected to both sides of the limiting ring 4. The sliding blocks 10 can abut against the inner wall of the sliding grooves 11. Therefore, when it is necessary to adjust the heating area of ​​the pot bottom, the limiting ring 4 is rotated through the through groove 3. At this time, the limiting ring 4 rotates correspondingly within the annular groove 7. Simultaneously, the sliding blocks 10 are displaced as the limiting ring 4 rotates, and then slide within the sliding grooves 11 until the sliding blocks 10 slide to the through groove 3. When the slider 10 separates from the slide groove 11, further movement of the limiting ring 4 separates it from the annular groove 7. This design facilitates the installation and removal of the limiting ring 4. By removing and installing the limiting ring 4, the heating area of ​​the pot bottom can be increased or decreased, allowing the heat received by the pot bottom to be adjusted according to the size of the food, thus improving the practicality of the pot body 1. Furthermore, this design effectively improves the heat utilization rate of the pot body 1. A slot 9 is provided on the inner wall of the slide groove 11. Simultaneously with the opening of the through groove 3 in the pot body 1, a slot 9 can be formed. The slot 9 and slide 11 are manufactured together using a grooving machine, thus saving processes and improving efficiency. A locking block 8 is fixedly connected to the slider 10, which can engage with the slot 9. When manufacturing the slider 10 and locking block 8, the slider 10 can be welded to the side wall of the limiting ring 4 using welding or other processes. Similarly, the locking block 8 can be welded to the side wall of the slider 10. Therefore, when the slider 10 slides to a certain position within the slide 11, the locking block 8 fixedly connected to the slider 10 engages with the slot 9 on the inner wall of the slide 11, thus limiting... Ring 4 is fixed in place, thereby achieving the function of fixing and limiting ring 4, avoiding affecting the normal use of pot body 1, and preventing the limiting ring 4 from rotating when pot body 1 is in use, so that slider 10 rotates to through groove 3. At this time, the limiting ring 4 separates from annular groove 7 due to gravity. Since the cross-section of slider 10 is rectangular, when slider 10 is located in sliding groove 11, slider 10 abuts against the inner wall of sliding groove 11, thereby limiting the range of motion of limiting ring 4, thus preventing limiting ring 4 from separating from annular groove 7 when pot body 1 is in use.

[0037] like Figures 2-4As shown, both the anti-deformation layer 12 and the limiting ring 4 are made of titanium-magnesium alloy. Because titanium-magnesium alloy is hard, not easily deformed, has a strong metallic luster, strong anti-deformation ability, is lightweight, and has good mechanical strength, the anti-deformation layer and limiting ring 4 made of titanium-magnesium alloy have strong anti-deformation ability and are lightweight, effectively improving the anti-deformation ability of the pot bottom, thus making the pot body 1 more convenient to use. Furthermore, because titanium-magnesium alloy is lightweight, it effectively avoids the improved pot body 1 being too heavy. This design makes the pot body 1 easier to use and further improves its practicality. The weight of the limiting rings 4 gradually decreases from the outside to the inside. This design allows the overall weight of the pot body 1 to be adjusted according to actual usage habits. During adjustment, the limiting ring 4 is rotated to separate the slider 10 from the slide groove 11, thus separating the limiting ring 4 from the annular groove 7, thereby achieving the effect of adjusting the weight of the pot body 1. This allows the pot body 1 to suit the usage habits of different people, further improving the practicality of the pot body 1.
