[0045] To make the purposes, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0046] The following description of the embodiments with reference to the drawings is merely representative of implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with the present application as recited in the appended claims.

For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

The character " / " generally represents a "or" relationship between the associated objects before and after it.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0049] The embodiments of the present application propose a pot support 1 and a stove, which comprises the pot support 1 and a burner. The pot support 1 defines a combustion chamber, and the pot support 1 is placed on the gas stove and surrounds the side of the burner. Along the height direction of the pot support 1, the combustion chamber at least partially coincides with the burner, so that the flame generated by the burner can be in the combustion chamber. Of course, the burner and the combustion chamber are completely coincident to make the gas emitted by the burner completely burn in the combustion chamber

[0050] Please refer to Figure 1 and Figure 2The pot support 1 comprises a pot support body 10, a plurality of support members 20 and support legs 30. The pot support body 10 is annularly arranged and defines the combustion chamber; the pot support body 10 can be circular, of course, according to actual requirements, the pot support body 10 can also be square or other shapes. In addition, the pot support body 10 can be cast iron, enamel or galvanized steel and other materials with the advantages of high temperature resistance, good strength and the like.

[0051] Please refer to Figure 3 The plurality of support members 20 are connected to the upper surface of the pot support body 10 and are arranged at intervals around the combustion chamber, and a flue gas passage 10a is formed between adjacent two support members 20, the flue gas passage 10a communicates the combustion chamber with the peripheral space of the pot support body 10, the plurality of support members 20 are separately arranged with the pot support body 10, and the support member 20 has a support surface 210 for supporting the pot, and the support surface 210 is a horizontal surface. It can be understood that the number of support members 20 should be three or more, and the included angle between the two farthest support members 20 of the at least three support members 20 along the circumference of the pot support body 10 should be greater than 180°, so that the support member 20 can support the pot; in order to realize the stable support of the at least three support members 20 to the pot, in some embodiments of the present application, the at least three support members 20 are equally spaced along the circumference of the pot support body 10. In addition, the support member 20 can be cast iron and other materials with high temperature resistance, which is not limited in the present embodiment.

[0052] The support legs 30 are arranged at the bottom of the pot support body 10 and are used to be placed on the table surface of the cooking bench and support the pot support body 10. The number of support legs 30 is multiple, and the plurality of support legs 30 are connected to the pot support body 10 at intervals along the circumference of the pot support 1 to improve the stability of the pot support body 10.

[0053] Based on the pot support 1 of the embodiment of the present application, the pot is supported by the plurality of support members 20 around the combustion chamber after being placed on the pot support 1, the plurality of support members 20 can increase the contact area with the flue gas, so that the temperature of the support member 20 is higher, and the support surface 210 of the support member 20 is a horizontal surface, so that the support member 20 has a larger contact area with the pot, which improves the heat conduction efficiency between the pot support 1 and the pot, and the heat transfer of the pot support 1 to the pot also improves the heat utilization rate of the gas stove. Further, the support member 20 absorbs the heat in the flue gas and transfers it to the upper surface of the pot support body 10, when the upper surface of the pot support body 10 has a high temperature, it will be transferred to the pot in the form of heat radiation, thereby improving the heating efficiency of the pot.

[0054] The greater contact area between the support 20 and the pot can improve the stability of the support 20 supporting the pot, prevent the pot from sliding or falling during heating, reduce the occurrence of accidental injury, and ensure the stability of the cooking process. In addition, the support 20 and the pot support body 10 are separately arranged, which can improve the production efficiency. For example, during production, the pot support body 10 is obtained by stamping, and the support 20 can be a cuboid plate structure, which is installed on the pot support body 10 by welding.

[0055] Referring to Figure 4 , along the height direction of the pot support body 10, the height H of the support 20 protruding relative to the upper surface of the pot support body 10 is not less than 4mm and not more than 11mm. The minimum height ensures that the support 20 can sufficiently protrude from the upper surface of the pot support body 10, ensuring that the support 20 has sufficient contact area with the flue gas. If the height of the support 20 protruding relative to the upper surface of the pot support body 10 is less than 4mm, firstly, the bottom of the pot is too close to the pot support body 10, which can affect the efficiency of flue gas exhaust, thereby affecting the combustion efficiency of the burner; secondly, the contact area between the support 20 and the flue gas is small, and the heat absorbed by the support 20 from the flue gas will be correspondingly reduced, and the heat that the support 20 can transfer to the pot is also limited, thereby reducing the overall heat conduction efficiency. If the height of the support 20 protruding relative to the upper surface of the pot support body 10 is greater than 11mm, the distance between the upper surface of the pot support body 10 and the bottom of the pot is too far, and the heat radiation conduction path is also correspondingly lengthened, which is difficult to effectively transfer to the bottom of the pot.

[0056] Further, the upper surface of the pot support body 10 is a horizontal plane. In this way, the distance between the upper surface of the pot support body 10 and the bottom of the pot is the same, ensuring that the bottom of the pot can uniformly receive heat radiation from the pot support 1. Moreover, it can also facilitate the production and installation of the support 20, and the support 20 does not need to be designed as a special shape, but can only be arranged as a cuboid structure with the same height and thickness.

[0057] Referring to Figure 3The thickness D of the support 20 along the circumferential direction of the pot support 1 is not less than 2 mm and not more than 6 mm. It can be understood that the support 20 needs to bear the weight of the pot and the food in the pot. If the thickness of the support 20 is too thin, the structural strength is small, and it is difficult to effectively support the pot. If the thickness of the support 20 is too thick, the amount of material used will increase, thereby increasing the manufacturing cost. Within the thickness range provided in the present application, the amount of material used can be minimized on the premise of ensuring performance, improving material utilization, and reducing manufacturing cost. Of course, the thickness of the support 20 and the number of the support 20 can be adaptively set. For example, when the number of the support 20 is small, the thickness of the support 20 can be set to be relatively large. When the number of the support 20 is large, the thickness of the support 20 can be set to be relatively small.

[0058] Please refer again to Figure 3 In order to ensure the effective exhaust of flue gas, the pot support 1 has a circle E passing through the inner wall surface of all the supports 20 along the circumferential direction of the pot support 1, and the ratio of the total arc length of the flue gas passages 10a on the circle E to the total arc length of all the supports 20 on the circle E is not less than 2:1 and not more than 11:1. Specifically, a large number of supports 20 can increase the contact area with the flue gas and increase the contact area with the pot, thereby improving the heat transfer efficiency of the pot support 1 to the pot. However, too many supports 20 will cause the flow area of the flue gas passages 10a to be small, which may hinder the smooth flow of flue gas, cause flue gas to accumulate in the combustion chamber, and affect the combustion efficiency and safety. Therefore, in the present application, the total arc length of the inlet of the flue gas passage 10a on the circle E is not less than two-thirds and not more than eleven-twelfths, which ensures the effective flow of flue gas.

[0059] It can be understood that in the case where the thickness of the support 20 is constant, the arc length of the inlet of the flue gas passage 10a on the circle E passing through the inner wall surface of all the supports 20 in the inner-outer direction of the pot support 1 is the smallest. That is, when the thickness of the support 20 is constant, the spacing between the adjacent two supports 20 in the circumferential direction of the pot support 1 gradually increases, and at this time the length of the flue gas passage 10a along the circumferential direction of the pot support 1 also gradually increases. The present application limits the arc length range of the minimum diameter of the flue gas passage 10a, thereby ensuring that the flow area of the flue gas passage 10a can effectively exhaust the flue gas. Of course, the thickness of the support 20 can not be a fixed value, that is, the thickness of the support 20 can gradually increase from the inside to the outside in the inner-outer direction of the pot support 1, but the spacing of the flue gas passage 10a in the inner-outer direction needs to be not less than the inlet spacing of the flue gas passage 10a.

[0060] In addition, the spacing between two adjacent supports 20 gradually increases in the circumferential direction of the pot support 1, that is, the extension direction of the support 20 is arranged at an angle with the radial direction of the pot support body 10. In this way, when the flue gas passes through the support 20, it will flow along the support 20, avoiding the flue gas directly discharging along the radial direction of the pot support body 10, thereby prolonging the residence time of the flue gas on the support 20, and achieving better heat exchange effect and more heat recovery of the support 20 and the flue gas.

[0061] Please continue to refer to Figure 3 In the inner-outer direction of the pot support 1, a first fillet 220 is formed between the inner side of the support 20 and the support surface 210, and a second fillet 230 is formed between the outer side of the support 20 and the support surface 210. Specifically, the inner side of the support 20 is directly heated by the burner flame, causing the temperature in this area to rise and generate thermal stress. The first fillet 220 can reduce this thermal stress concentration phenomenon, making the heat distribution more uniform, thereby prolonging the service life of the pot support 1. During use, the placement and movement of the cookware can cause some wear to the outer side of the support 20. The second fillet 230 can reduce the occurrence of this wear phenomenon, and the second fillet 230 can also prevent accidental injury when the user uses it.

[0062] In some embodiments, please refer to Figure 4 to Figure 6 A heat insulation cavity 10b is formed inside the pot support body 10; the pot support 1 further comprises at least one partition 40, which is arranged inside the heat insulation cavity 10b and separates the heat insulation cavity 10b into a first sub-cavity 10b1 and a second sub-cavity 10b2 from top to bottom in the height direction of the pot support 1, and the thickness of the first sub-cavity 10b1 is less than that of the second sub-cavity 10b2. The main function of the heat insulation cavity 10b is to reduce the heat exchange between the inside and outside of the pot support body 10. During cooking, the pot support 1 will be subjected to heat radiation from the burner, and the heat insulation cavity 10b can effectively block these heat from being directly transmitted to the outside of the pot support 1. First, it reduces the paths of heat conduction and heat radiation, so that the pot support 1 can better concentrate heat and efficiently transfer it to the cookware, so that the cookware can reach the required cooking temperature faster, thereby improving the cooking efficiency; second, it can reduce the temperature of the kitchen environment and improve the comfort of cooking.

[0063] During combustion, please refer to Figure 1, the upper surface of the pot support body 10 will radiate heat to the pot, in order to reduce the heat loss of the upper surface of the pot support body 10, the partition 40 of the present application divides the heat insulation cavity 10b into a first sub-cavity 10b1 and a second sub-cavity 10b2 from top to bottom in the height direction of the pot support 1, and the thickness of the first sub-cavity 10b1 is smaller than that of the second sub-cavity 10b2. Specifically, the upper surface of the pot support body 10 is connected with the support 20, and the outer wall surface of the support 20 and the upper surface of the pot support body 10 will be in contact with the flue gas, thereby increasing the heat. As the temperature of the upper surface of the pot support body 10 rises, the air in the heat insulation cavity 10b will also be heated and expand, and will have a violent thermal motion, forming a convection. This convection heat transfer will promote the heat transfer between the top wall 111 of the pot support body 10 and the bottom wall and the outer side wall of the pot support body 10, so that part of the heat of the top wall 111 of the pot support body 10 is lost.

[0064] In order to limit the intensity of such convection heat transfer and reduce the heat loss of the top wall 111 of the pot support body 10, the partition 40 of the present application divides the heat insulation cavity 10b into a first sub-cavity 10b1 and a second sub-cavity 10b2 from top to bottom in the height direction of the pot support 1, so that the space between the top wall 111 of the pot support body 10 and the partition 40 (i.e. the first sub-cavity 10b1) becomes narrow, thereby increasing the resistance of air flow and reducing the convection speed of air, thereby reducing the intensity of convection heat transfer, and avoiding the heat of the top wall 111 of the pot support body 10 being transferred to the partition 40 by air convection. In addition, the partition 40 blocks the path of heat transfer of the top wall 111 of the pot support body 10 to the bottom surface and the outer side wall, further reducing the heat loss.

[0065] Please refer to Figure 5 The partition 40 includes a partition plate 410, which is arranged in the height direction of the top wall 111 of the pot support body 10, and in some embodiments, the partition plate 410 is a corrugated plate 411, which forms a plurality of wave crests 411a and a plurality of wave troughs 411b connected alternately in the radial direction of the combustion chamber. The uneven surface of the corrugated plate 411 greatly increases the resistance of air flow, so that the convection motion of air in the first sub-cavity 10b1 is further inhibited. Therefore, it is more difficult for the heat of the top wall 111 of the pot support body 10 to be transferred to the partition plate 410 by air convection, further reducing the heat loss of the top wall 111 of the pot support body 10.

[0066] Please refer to Figure 5Along the height of the pot support 1, the distance h1 between the bottom of the trough 411b and the top wall 111 of the pot support body 10 is no less than 2 mm and no more than 5 mm. Along the height of the pot support 1, the distance h2 between the peak of the peak 411a and the top wall 111 of the pot support body 10 is no more than 1 mm. The minimum distance h1 of 2 mm between the bottom of the trough 411b and the top wall 111 ensures sufficient space in the trough 411b area and allows for a certain degree of air flow. This distance also prevents direct contact between the partition plate 410 and the top wall 111, thereby reducing heat loss due to contact heat conduction. The minimum distance h1 of 5 mm between the bottom of the trough 411b and the top wall 111 limits the maximum depth of the trough 411b and prevents the formation of excessive vortices within the trough 411b, which could increase the intensity of convective heat transfer.

[0067] Because the wave crests 411a and troughs 411b alternate radially along the combustion chamber, the corrugated plate 411 and the top wall 111 of the pot support body 10 divide the first sub-chamber 10b1 into multiple annular cavities spaced radially apart from each other. The distance h2 between the peaks of the wave crests 411a and the top wall 111 is no greater than 1 mm, minimizing convection between the various annular cavities. Because the burner is mounted on the inner surface of the pot support body 10, this area is directly heated by the flame. Therefore, the annular cavities closer to the inner surface of the pot support body 10 receive more heat. However, the multiple annular cavities are designed to hinder convection, making it difficult for air in the inner annular cavities to disperse into the outer annular cavities. This further reduces the efficiency of heat exchange between the air in the first sub-chamber 10b1 and the partition plate 410, and reduces the heat dissipation from the top wall 111 of the pot support body 10.

[0068] In other embodiments, see Figure 6 The partition plate 410 is a flat plate 412. The thickness of the first sub-cavity 10b1 in the height direction of the pot support 1 is no less than 1 mm and no more than 5 mm. In this embodiment, the partition plate 410 has a relatively simple structure, improving processing efficiency. Furthermore, the thickness of the first sub-cavity 10b1 is no less than 1 mm and no more than 5 mm. Setting the first sub-cavity 10b1 within this range not only prevents the partition plate 410 from contacting the top wall 111 of the pot support body 10 during installation, but also limits the maximum thickness of the first sub-cavity 10b1, thereby weakening the intensity of air convection within the first sub-cavity 10b1.

[0069] In some other embodiments, see Figure 7The partition plate 410 includes a horizontal plate 413 and a plurality of vertical plates 414. The horizontal plate 413 is spaced apart from the top wall 111 of the pot support body 10 in the height direction. The plurality of vertical plates 414 are connected to the upper surface of the horizontal plate 413 to form a plurality of annular grooves 415 spaced apart from each other from the inside to the outside of the horizontal plate 413. In this embodiment, the spacing between the vertical plates 414 and the top wall 111 of the pot support body 10 can be set with reference to the spacing between the peaks of the wave crests 411a and the top wall 111 of the pot support body 10 described above. The spacing between the horizontal plates 413 and the top wall 111 of the pot support body 10 can be set with reference to the spacing between the bottoms of the wave troughs 411b and the top wall 111 of the pot support body 10 described above.

[0070] Optionally, the first sub-cavity 10b1 is filled with a heat insulator. This can further reduce the air circulation space in the first sub-cavity 10b1 and reduce the intensity of air convection. The heat insulator can be in the form of ceramic fiber, aerogel, mineral wool, glass fiber, etc.

[0071] The pot support body 10 has an inner side facing the combustion chamber, with an opening 10d connecting the insulation chamber 10b with the combustion chamber. The divider 40 also includes an extension plate 416 connected to the side of the divider 410 closest to the combustion chamber. The extension plate 416 divides the opening 10d into a first opening 10e connecting to the first sub-chamber 10b1 and a second opening 10f connecting to the second sub-chamber 10b2. As will be appreciated, the burner is mounted on the inner side of the pot support body 10, so the annular cavity near the inner side of the pot support body 10 receives more heat. The opening 10d provided on the inner side of the pot support body 10 in this application prevents heat from the top wall 111 of the pot support body 10 from being transferred downward.

[0072] Further, along the height direction of the pot support 1, please refer to Figure 8 The thickness of the first opening 10e is less than that of the second opening 10f. This means that the partition plate 410 is further away from the bottom wall of the pot support body 10 than the top wall 111 of the pot support body 10, preventing heat from the partition plate 410 from being transferred to the bottom wall of the pot support body 10. Optionally, the thickness of the first opening 10e along the height of the pot support 1 is no greater than 1 mm, reducing the possibility of external air and impurities entering the insulating cavity 10b.

[0073] The wok support body 10 includes an inner sidewall 112 facing the combustion chamber. The top end of the inner sidewall 112 connects to the top wall 111. The inner sidewall 112 has an opening 10d and is tilted upward in the radial direction of the combustion chamber. The extension plate 416 is spaced apart from the inner sidewall 112. When the burner is operating, the flame spreads outward, creating a relatively large heat radiation area. This area encompasses not only the high-temperature portion of the flame itself, but also the heated air and gas surrounding the flame. The upward tilt of the inner sidewall 112 more effectively directs the heat generated by the flame upward, reducing horizontal heat diffusion. This allows the heat to be more concentrated at the bottom of the pot, improving cooking efficiency. The extension plate 416 is spaced apart from the inner sidewall 112, limiting the gap between the extension plate 416 and the inner sidewall 112, thereby restricting air convection and reducing the heat transfer efficiency of the top wall 111 of the wok support body 10.

[0074] In some structural forms, please refer to Figure 4 and Figure 9 The pot support body 10 includes an upper cover 110 and a lower cover 120 connected to each other, which together form an insulating cavity 10b. The outer peripheral wall of the partition 40 is connected to the inner wall of the upper cover 110, and the outer peripheral wall of the upper cover 110 is fixedly connected to the outer peripheral wall of the lower cover 120. The upper cover 110 can form the top wall 111 and a portion of the inner side wall 112 of the pot support body 10, while the lower cover 120 can form the bottom wall, a portion of the outer side wall, and a portion of the inner side wall 112 of the pot support body 10. The connection points between the partition 40 and the upper cover 110, as well as the connection points between the upper cover 110 and the lower cover 120, are both located away from the burner. This facilitates the formation of the aforementioned opening 10d and reduces the risk of heat from the upper cover 110 being directly transferred to the lower cover 120, thereby reducing heat loss and improving the thermal insulation effect. The upper cover 110 and the lower cover 120 as well as the upper cover 110 and the partition plate 410 may be connected by welding.

[0075] In some embodiments, multiple dividers 40 are provided, and the dividers 40 are spaced apart along the height of the pot support 1 to divide the insulating cavity 10b into multiple sub-cavities along the height of the pot support 1. The thickness of the uppermost sub-cavity is smaller than that of the remaining sub-cavities along the height of the pot support 1. This further limits the convection efficiency of the air within the insulating cavity 10b, further reducing the efficiency of downward heat transfer, and effectively improving the thermal insulation performance of the pot support 1.

[0076] Optionally, in the height direction of the pot support 1, in any two adjacent sub-cavities, the thickness of the upper sub-cavity is smaller than that of the lower sub-cavity. In this way, the convection of air in the upper sub-cavity is weaker than that in the lower sub-cavity, so that the heat can be better retained in the upper position of the pot support 1, thereby improving the heating efficiency of the pot support 1 on the pot.
