When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0039] The present utility model provides a flow guiding bracket and a pot bracket applying the flow guiding bracket. The flow guiding bracket (also called a flow guiding ring or a flow guiding plate) can be erected on an energy concentrating bracket (also called an energy concentrating ring or an energy concentrating plate) to jointly form a pot bracket applied to a cooker.

[0040] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the pot bracket 101 includes a first bracket 10 (i.e., the energy concentrating bracket) and a second bracket 70 (i.e., the flow guiding bracket). The first bracket 10 encloses a central hole 102, and the second bracket 70 is arranged on the first bracket 10; the second bracket 70 is arranged around the central hole 102 and is located on one side close to the central hole 102 at the top of the first bracket 10.

[0041] Without loss of generality, the pot bracket 101 is usually arranged on the liquid receiving tray of the cooker and is used for placing a piece to be heated, such as a cooking utensil (including but not limited to a flat pan, a pointed bottom pan, etc.). Specifically, when the pot bracket 101 is installed on the cooking surface of the cooker, the central hole 102 of the first bracket 10 can accommodate the burner of the cooker and is used to enable the flame formed by the burner to act on the bottom surface of the cooking utensil. Through the central hole 102 enclosed by the first bracket 10, the flame generated by the burner can be enclosed within the first bracket 10 as much as possible, so that the heat of the flame generated by the burner is concentrated in the area where the central hole 102 is located as much as possible, thereby achieving an energy concentrating effect and improving the thermal efficiency of the cooker.

[0042] On this basis, by adding a second bracket 70 to the first bracket 10, since the second bracket 70 is arranged around the central hole 102 and is closer to the central hole 102, the flame generated by the burner can be enclosed within the second bracket 70 as much as possible, so that the heat of the flame generated by the burner is concentrated within the second bracket 70 to the greatest extent, forming a high-temperature area within the area of the second bracket 70 and a low-temperature area within the area between the second bracket 70 and the first bracket 10. Then, the flame and high-temperature flue gas within the high-temperature area mainly heat the cooking utensil, thereby improving the thermal efficiency of the cooker.

[0043] When the spreading area of the flame formed by the burner is relatively large, the flame will directly contact the tops of the first bracket 10 and the second bracket 70 and transfer heat to the first bracket 10 and the second bracket 70, resulting in the first bracket 10 and the second bracket 70 being heated to a relatively high temperature.

[0044] It can be understood that the higher the temperature of an object, the greater the total energy it radiates. When using the cooker, since a high-temperature area is formed within the area of the second bracket 70, the second bracket 70 has a higher temperature. If more heat of the second bracket 70 can be transferred to the cooking utensil in the form of thermal radiation, the thermal efficiency of the cooker can be improved.

[0045] Therefore, optionally in the embodiment of the present utility model, at least part of the upper surface of the second bracket 70 is covered with a far-infrared radiation structure (not shown in the drawings). In this way, through the far-infrared radiation structure, more energy of the second bracket 70 can be converted into thermal radiation energy and radiated to the cooking utensil, thereby utilizing part of the heat that would otherwise dissipate naturally, and further improving the thermal efficiency of the cooker. Of course, in other embodiments, the far-infrared radiation structure may not be provided, or the far-infrared radiation structure may be provided on the upper surface of the first bracket 10.

[0046] Optionally, the far-infrared radiation structure is configured as an enamel layer, and the far-infrared radiation structure covers the upper surface of the second bracket 70. That is, an enamel layer is formed on the upper surface of the second bracket 70 by using an enamel process, and the material used in the enamel process is a far-infrared radiation enamel material. In this way, using the enamel layer as the far-infrared radiation structure can not only endow the second bracket 70 with good far-infrared radiation performance, but also make the second bracket 70 easy to clean and improve its aesthetics.

[0047] Of course, in some other embodiments, it may also be that the far-infrared radiation structure only covers the upper surface of the top of the second bracket 70. In other embodiments, other far-infrared radiation structures may also be used, such as setting a graphene layer on the upper surface of the second bracket 70 to utilize the good far-infrared radiation effect of the graphene layer.

[0048] Please refer to Figure 1, Further, the pot support 101 further includes an upper support 50. The upper support 50 is provided on the top of the first support 10 and / or the second support 70 to support the item to be heated. In this way, a gap can be formed between the bottom surface of the cooking utensil and the upper surfaces of the first support 10 and the second support 70, which is beneficial for the flame generated by the burner to spread freely, and enables more sufficient combustion and heat exchange.

[0049] Of course, in other embodiments, the upper support 50 may not be provided, and the upper surfaces of the first support 10 and / or the second support 70 may be directly used to support the item to be heated. On this basis, in order to enable the flame generated by the burner to spread freely, avoidance through grooves may be provided on the upper surfaces of the first support 10 and the second support 70. The avoidance through grooves penetrate through the opposite sides of the first support 10 and the second support 70 in the radial direction of the central hole 102. In this way, the flame and flue gas can flow in the avoidance through grooves.

[0050] Without loss of generality, when the burner of the cooking appliance burns, it usually generates a certain amount of high-temperature flue gas. These high-temperature flue gases usually spread freely along the bottom surface of the cooking utensil quickly, which causes the high-temperature flue gases to not be able to come into full contact with the cooking utensil and perform heat exchange, and further results in low thermal efficiency of the cooking appliance.

[0051] In order to improve the utilization rate of the high-temperature flue gas to improve the thermal efficiency of the cooking appliance, please refer to Figure 1 , Figure 3 and Figure 5 , Further, the top of the second support 70 has a guiding surface 70a provided around the central hole 102, and the top of the upper support 50 has a bearing surface 50a for supporting the item to be heated. The guiding surface 70a is lower than the bearing surface 50a.

[0052] Specifically, place the cooking utensil on the upper support 50 so that the bottom surface of the cooking utensil abuts against the bearing surface 50a of the upper support 50. Since the height of the bearing surface 50a is higher than the guiding surface 70a of the second support 70, a gap is formed between the guiding surface 70a and the bottom of the cooking utensil. Under the guiding action of the guiding surface 70a, the high-temperature flue gas flows from the high-temperature area to the low-temperature area along the gap between the guiding surface 70a and the bottom of the cooking utensil, and heats the cooking utensil during the flowing process. Finally, it flows out of the first support 10 through the gap between the top of the first support 10 and the bottom of the cooking utensil, so that the high-temperature flue gas can perform sufficient heat exchange with the cooking utensil.

[0053] Moreover, since the flame of the burner and the high-temperature flue gas generated by the burner heat the top of the second bracket 70, the top of the second bracket 70 can also play a role in heat exchange with the cooking utensil, so as to further improve the heating effect. In particular, when a far-infrared radiation structure is covered on the upper surface of the second bracket 70, the heat transferred from the high-temperature flue gas to the second bracket 70 can be radiated to the bottom of the cooking utensil via the far-infrared radiation structure, thereby further improving the thermal efficiency of the cooker.

[0054] It can be understood that in this embodiment, the gap between the guiding surface 70a and the bottom of the cooking utensil forms a smoke exhaust passage 103 for the high-temperature flue gas. The high-temperature flue gas can flow from the inside out along the smoke exhaust passage 103 until it reaches the outer peripheral circle of the second bracket 70. If the width of the guiding surface 70a in the radial direction of the central hole 102 is wider, the length of the smoke exhaust passage 103 in this direction can be made larger, which is more conducive to the full heat exchange between the high-temperature flue gas and the cooking utensil, and thus more conducive to improving the thermal efficiency of the cooker. However, considering that the larger the width of the guiding surface 70a, the less conducive it is to the local structural strength of the second bracket 70 in the area where the guiding surface 70a is located, and the greater the risk of incomplete combustion of the flame in the high-temperature area and high carbon monoxide content.

[0055] Therefore, in this embodiment, optionally, the width of the guiding surface 70a in the radial direction of the central hole 102 ranges from 10 mm to 20 mm, for example, 12 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, etc. In this way, the width of the guiding surface 70a is moderate, which is not only conducive to the full combustion of the flame and the full heat exchange between the high-temperature flue gas and the cooking utensil, thus being conducive to improving the thermal efficiency of the cooker, but also can ensure that the second bracket 70 has sufficient structural strength.

[0056] Further optionally, the width of the guiding surface 70a in the radial direction of the central hole 102 ranges from 15 mm to 18 mm, and the material thickness of the first bracket 10 ranges from 1 mm to 1.5 mm. In this way, the first bracket 10 can not only have good structural strength, and its weight will not be too large, which is conducive to reducing the manufacturing cost of the first bracket 10, but also enable the second bracket 70 to have a wider guiding surface 70a. Of course, in other embodiments, the material thickness of the first bracket 10 can also be less than 1 mm or greater than 1.5 mm, for example, 3 mm.

[0057] To further improve the utilization rate of the high-temperature flue gas, please refer to Figure 3 、 Figure 5 and Figure 8, optionally, the top of the first bracket 10 has a smoke exhaust surface 11a, the smoke exhaust surface 11a surrounds the outer peripheral circle of the diversion surface 70a, and the smoke exhaust surface 11a is lower than the bearing surface 50a. It can be understood that the gap between the diversion surface 70a and the bottom of the cooking utensil, and the gap between the smoke exhaust surface 11a and the bottom of the cooking utensil together constitute the smoke exhaust channel 103 for high-temperature flue gas. By adding the smoke exhaust surface 11a, the total length of the smoke exhaust channel 103 in the radial direction of the central hole 102 can be increased, thereby extending the heat exchange time between the flue gas and the bottom of the cooking utensil, and further improving the utilization rate of the high-temperature flue gas. Of course, in other embodiments, the smoke exhaust surface 11a may not be provided.

[0058] Please refer to Figure 5 , optionally, the smoke exhaust surface 11a and the diversion surface 70a are arranged in a plane and are arranged in parallel with the plane where the central hole 102 is located. It should be noted that being arranged in parallel means being parallel and nearly parallel, that is, the axis of the central hole 102 is perpendicular or approximately perpendicular to the smoke exhaust surface 11a and the diversion surface 70a in space. In this way, a good guiding effect can be exerted on the flue gas in the smoke exhaust channel 103. Of course, in other embodiments, one of the smoke exhaust surface 11a and the diversion surface 70a may be arranged in a plane, or the smoke exhaust surface 11a and the diversion surface 70a intersect with the plane where the central hole 102 is located in space. For example, the diversion surface 70a forms an angle of 10° to 20° with the plane where the central hole 102 is located. In other embodiments, the smoke exhaust surface 11a and the diversion surface 70a may also be arranged in a curved surface.

[0059] Please refer to Figure 5 and Figure 6 , optionally, a buffer gap 104 is formed between the smoke exhaust surface 11a and the diversion surface 70a. In this way, when the high-temperature flue gas flows outward along the diversion surface 70a of the second bracket 70, a phenomenon of partial airflow detachment will occur at the buffer gap 104, and eddy currents will be generated here, which can disrupt the originally smooth laminar flow of the high-temperature flue gas, be conducive to extending the residence time of the high-temperature flue gas in the smoke exhaust channel 103, and thus extending the heat exchange time between the high-temperature flue gas and the bottom of the cooking utensil. Of course, in other implementations, the buffer gap 104 may not be provided. For example, the smoke exhaust surface 11a and the diversion surface 70a are arranged in zero-gap butt joint in the radial direction of the central hole 102.

[0060] Please refer to Figure 5 and Figure 8 , further, the smoke exhaust surface 11a is higher than the diversion surface 70a, and the upper surface of the first bracket 10 also has a guiding surface 11b connected to the inner periphery of the smoke exhaust surface 11a. The guiding surface 11b extends downward and forms a buffer gap 104 with the diversion surface 70a at an interval. A buffer cavity 105 is formed between the guiding surface 11b and the second bracket 70 at an interval, and the buffer cavity 105 communicates with the lower side of the buffer gap 104.

[0061] Thus, on the one hand, since the smoke exhaust surface 11a is higher than the diversion surface 70a, it can play a certain obstructive role in the flue gas flowing through the buffer gap 104. On the other hand, affected by the guiding surface 11b and the buffer gap 104, the flue gas separated at the buffer gap 104 can smoothly enter the buffer chamber 105, which is conducive to forming more and more significant eddy currents at the buffer gap 104 for the high-temperature flue gas, thereby further prolonging the heat exchange time between the high-temperature flue gas and the bottom of the cooking utensil. Of course, in other embodiments, the buffer chamber 105 may not be provided. For example, the guiding surface 11b extends from the inner periphery of the smoke exhaust surface 11a towards the central hole 102 and extends to abut against the lower surface opposite to the diversion surface 70a on the upper side wall of the second bracket 70.

[0062] Optionally, the guiding surface 11b extends obliquely downward in the direction close to the central hole 102, and the minimum distance between the diversion surface 70a and the guiding surface 11b in the radial direction of the central hole 102 ranges from 5 mm to 15 mm. Specifically, optionally, the minimum distance is 6 mm, 8 mm, 10 mm or 12 mm, etc.

[0063] It can be understood that the minimum distance between the diversion surface 70a and the guiding surface 11b in the radial direction of the central hole 102 is positively correlated with the width of the buffer gap 104. Therefore, if the minimum distance is too small, the width of the buffer gap 104 will correspondingly be too small, which is not conducive to generating obvious and effective eddy currents in the buffer gap 104. If the minimum distance is too large, the width of the buffer gap 104 will correspondingly be too large, which is likely to cause the high-temperature flue gas to be unable to smoothly flow away along the smoke exhaust passage 103 and diffuse disorderly, and the high-temperature flue gas cannot achieve the further heating effect on the cooking utensil as originally designed.

[0064] Optionally, the height difference between the smoke exhaust surface 11a and the bearing surface 50a ranges from 3 mm to 9 mm, and the height difference between the diversion surface 70a and the bearing surface 50a ranges from 3 mm to 9 mm. It can be understood that both the height difference between the smoke exhaust surface 11a and the bearing surface 50a and the height difference between the diversion surface 70a and the bearing surface 50a are positively correlated with the height of the smoke exhaust passage 103. Therefore, if these two height differences are too small, it is not conducive to the smooth flow of the high-temperature flue gas. If these two height differences are too large, the flow rate of the high-temperature flue gas is too large and it is not conducive to prolonging its heat exchange time with the cooking appliance. Of course, in other embodiments, the height difference between the smoke exhaust surface 11a and the bearing surface 50a may also be less than 3 mm or greater than 9 mm, or the height difference between the diversion surface 70a and the bearing surface 50a may also be less than 3 mm or greater than 9 mm.

[0065] In an embodiment where the smoke exhaust surface 11a is higher than the diversion surface 70a, optionally, the height difference between the smoke exhaust surface 11a and the bearing surface 50a is 5 mm to 6 mm, and the height difference between the diversion surface 70a and the bearing surface 50a is 4 mm to 5 mm. Thus, the flow velocity of the high-temperature flue gas in the smoke exhaust passage 103 can be effectively reduced.

[0066] Please refer to Figure 1 and Figure 3 , optionally, the center line of the smoke exhaust surface 11a extending along the circumferential direction of the central hole 102 is arranged in a regular polygon, and the center line of the diversion surface 70a extending along the circumferential direction of the central hole 102 is arranged in a circular shape. For example, the center line of the smoke exhaust surface 11a in this embodiment is in a square shape. Of course, the center line of the smoke exhaust surface 11a can also be in a regular pentagon, regular hexagon, etc. Without loss of generality, the perimeter of a regular polygon is always greater than the perimeter of its inscribed circle. Therefore, designing the center line of the smoke exhaust surface 11a as a regular polygon can make the perimeter of the smoke exhaust surface 11a in the circumferential direction of the central hole 102 larger, which is beneficial to increasing the equivalent length of the smoke exhaust passage 103 and increasing the heat exchange area and duration between the high-temperature flue gas and the cooking utensil.

[0067] On the other hand, since the center line of the diversion surface 70a is arranged in a circular shape, the center line of the buffer gap 104 located on the outer periphery of the diversion surface 70a is also approximately circular. Thus, when the high-temperature flue gas flows outward from the central hole 102 in different directions, vortices can be generated at approximately the same circumferential position (i.e., the position corresponding to the buffer gap 104), so that the flow field of the high-temperature flue gas in the smoke exhaust passage 103 is more stable, and the heat is more evenly concentrated in the high-temperature area, which is beneficial to improving the thermal efficiency of the cooker.

[0068] Of course, in other embodiments, the center line of the smoke exhaust surface 11a extending along the circumferential direction of the central hole 102 can also be in a regular shape such as a circular shape, an elliptical shape or an inner polygon, or the center line of the diversion surface 70a extending along the circumferential direction of the central hole 102 can be in a regular shape such as an outer polygon, an inner polygon or an elliptical shape. For example, the center lines of both the smoke exhaust surface 11a and the diversion surface 70a are in a circular shape; or the center lines of the smoke exhaust surface 11a and the diversion surface 70a are arranged in an irregular shape.

[0069] Please refer to Figure 3 , it can be understood that in an embodiment where the center line of the smoke exhaust surface 11a is a regular polygon and the center line of the diversion surface 70a is a circular shape, when the centers of the regular polygon and the circular shape coincide, the minimum distance between the diversion surface 70a and the guiding surface 11b in the radial direction of the central hole 102 corresponds to the center position of the side of the regular polygon, and at the same time, the maximum distance between the diversion surface 70a and the guiding surface 11b in the radial direction of the central hole 102 corresponds to the corner (sharp corner) position of the regular polygon.

[0070] The structural form of the second support 70 has various types. For example, please refer to Figure 5 and Figure 7 , in an embodiment, the second support 70 includes a first ring plate 71 and a second ring plate 72 connected to the inner peripheral edge of the first ring plate 71. The second ring plate 72 extends downward and obliquely in the direction close to the central hole 102, and a diversion surface 70a is provided on the upper surface of the first ring plate 71. In this way, the second ring plate 72 extending downward and obliquely can play a certain guiding role in the flame and high-temperature flue gas in the central hole 102, so that the flame can spread better under the cooking utensil, and the high-temperature flue gas can flow more smoothly from the high-temperature area to the low-temperature area. Of course, in other embodiments, the second ring plate 72 may not be provided.

[0071] In order to improve the structural strength of the second support 70, further, the second support 70 further includes an outer strengthening flange 73 bent downward from the outer peripheral edge of the first ring plate 71. In this way, the structural strength of the area where the diversion surface 70a is located can be improved, which is beneficial for the diversion surface 70a to better maintain its designed position and play a good diversion effect on the high-temperature flue gas. Optionally in this embodiment, the second support 70 further includes an inner strengthening flange 74 bent from the inner peripheral edge of the second ring plate 72. In this way, the structural strength of the second support 70 can be further improved. Of course, in other embodiments, only the outer strengthening flange 73 or the inner strengthening flange 74 may be provided, or neither the outer strengthening flange 73 nor the inner strengthening flange 74 may be provided.

[0072] In an embodiment where there is a buffer gap 104 on the outer periphery of the diversion surface 70a, optionally, the outer strengthening flange 73 is configured to be bent downward from the outer peripheral edge of the first ring plate 71. In this way, the outer strengthening flange 73 will not only not interfere with the process of the high-temperature flue gas generating eddies in the buffer gap 104, but also play a certain promoting effect on the generation of eddies. Optionally in this embodiment, the upper surface of the outer strengthening flange 73 and the diversion surface 70a are smoothly transitioned. In this way, on the one hand, the intersection area between the outer strengthening flange 73 and the diversion surface 70a, and the outer strengthening flange 73 can jointly play the role of the wall attachment effect to promote the generation of more significant and more eddies in the buffer gap 104 by the high-temperature flue gas; on the other hand, the second support 70 with a smoother outer surface and no sharp convex structure can reduce the risk of users being cut by the second support 70.

[0073] Of course, in other embodiments, the outer strengthening flange 73 may also be configured to be bent upward from the outer peripheral edge of the first ring plate 71.

[0074] Please refer to Figure 5, in an embodiment where a buffer cavity 105 is formed at an interval between the guiding surface 11b and the second bracket 70, optionally, the outer reinforcing flange 73 and the first bracket 10 are arranged at an interval in the radial direction of the central hole 102, that is, there is a gap between the outer reinforcing flange 73 and the guiding surface 11b, and this gap is part of the buffer cavity 105. Of course, in other embodiments, the outer reinforcing flange 73 may also be in contact with the guiding surface 11b.

[0075] Optionally, the inner peripheral edge of the second ring plate 72 is bent upward to form an inner reinforcing flange 74, and the inner reinforcing flange 74 extends upward obliquely in a direction away from the first ring plate 71. In this way, the upwardly bent inner reinforcing flange 74 neither affects the expansion of the flame in the central hole 102 and the flow of high-temperature flue gas, nor can it jointly define an annular receiving groove with the upper surface of the second ring plate 72. When the cookware overflows with liquid or food, the annular receiving groove can play a certain role in receiving these overflows and prevent these overflows from directly flowing to the central hole 102 and the burner. Of course, in other embodiments, the inner peripheral edge of the second ring plate 72 may also be bent downward to form an inner reinforcing flange 74.

[0076] Optionally, at least one of the upper surfaces of the first ring plate 71, the second ring plate 72, the outer reinforcing flange 73 and the inner reinforcing flange 74 is covered with a far-infrared radiation structure. For example, in this embodiment, the upper surface of the second bracket 70 is covered with a far-infrared radiation structure, and the far-infrared radiation structure is configured as an enamel layer. In this way, not only can the second bracket 70 have better far-infrared radiation performance, but it is also easy to clean and more beautiful.

[0077] There is a gap between the second bracket 70 and the first bracket 10 in the axial direction of the central hole 102. In this way, the heat conduction phenomenon caused by the direct contact between the second bracket 70 and the first bracket 10 can be avoided, so that the heat of the second bracket 70 can be retained on its own structure as much as possible, which is beneficial to improving the thermal efficiency of the cooker. For example, please refer to Figure 5 , in an embodiment where the second bracket 70 has a second ring plate 72 and an inner reinforcing flange 74, the connection between the second ring plate 72 and the inner reinforcing flange 74 is the lowest point of the second bracket 70, and there is a gap in the up-down direction between this lowest point and the upper surface of the first bracket 10. Of course, in other embodiments, the lower surface of the second bracket 70 may also be in contact with the upper surface of the first bracket 10.

[0078] Please refer to Figure 1 and Figure 3 , in an embodiment where the center line of the smoke exhaust surface 11a is a regular polygon and the center line of the diversion surface 70a is a circle, optionally, the upper support 50 includes a second support 52 provided on the second bracket 70, and the second support 52 is arranged opposite to the corner of the smoke exhaust surface 11a. For example, in Figure 3In the illustrated embodiment, the center line of the smoke exhaust surface 11a is square, and the second supports 52 are distributed corresponding to the four corners (sharp corners) of the square. It can be understood that when the bottom surface of the cooking utensil completely covers the diversion surface 70a and the smoke exhaust surface 11a, the length of the smoke exhaust passage 103 in the direction corresponding to the corners of the polygon is the largest, and the high-temperature flue gas flowing through this direction has a longer duration of heat exchange with the cooking utensil.

[0079] Correspondingly, the length of the smoke exhaust passage 103 in the direction corresponding to the center of the side of the polygon is the smallest. By arranging the second supports 52 at other positions away from this direction, it is possible to avoid the second supports 52 directly interfering with the high-temperature flue gas in this direction (i.e., corresponding to the center position of the side of the regular polygon), which is beneficial to generating more and more significant eddies of the high-temperature flue gas in this direction, thereby prolonging the heat exchange duration of the high-temperature flue gas in this direction.

[0080] In this way, the high-temperature flue gas flowing outwards from the central hole 102 along different directions can basically achieve a better further heat exchange effect, thereby further improving the thermal efficiency of the stove. Of course, in other embodiments, the second supports 52 can also be arranged at positions opposite to the center of the side of the smoke exhaust surface 11a, or other positions.

[0081] Please refer to Figure 6 , further, the second support 52 includes an upper bearing portion 521. The upper bearing portion 521 is arranged on the upper surface of the second bracket 70, and the bearing surface 50a is arranged on the upper surface of the upper bearing portion 521. In this way, the second bracket 70 can play a good supporting role for the upper bearing portion 521.

[0082] In order to improve the adaptability of the pot support 101 so that the pot support 101 can be applicable to cooking utensils of more size specifications, please refer to Figure 1 and Figure 5 , further, the upper support 50 further includes a first support 51. The first support 51 is arranged on the top of the first bracket 10. The top surface of the upper bearing portion 521 is not higher than the top surface of the first support 51, and the inner edge of the projection area formed by the positive projection of the upper bearing portion 521 towards the plane where the central hole 102 is located is located within the central hole 102.

[0083] It can be understood that when the user uses a cooking utensil with a relatively large bottom width dimension, such as a frying pan with a diameter of 32 cm, the generally flat bottom surface of the cooking utensil will at least abut against the top surface of the first support 51 (when the top surface of the upper bearing portion 521 is flush with the top surface of the first support 51, it will also abut against the top surface of the upper bearing portion 521) and be supported by the first support 51. At this time, the height difference between the bottom surface of the cooking utensil and the burner conforms to the ideal design state, so that the flame and high-temperature flue gas generated by the burner can play a heat exchange role according to the ideal design state, and the thermal efficiency of the stove can basically reach the ideal design goal.

[0084] When a user uses a cooking utensil with a relatively small bottom width dimension, such as a splashing oil pan with a pot mouth diameter of 14 cm, the bottom surface of the splashing oil pan cannot contact the first support 51, resulting in the user having to hold the splashing oil pan by hand for heating. In the related art, the user can purchase a small-sized movable pot support 101 by himself / herself and place the movable pot support 101 on the first support 51 of the pot support 101 configured by the stove factory to use the movable pot support 101 to support the small-sized splashing oil pan. Since the movable pot support 101 is supported by the first support 51, the upper surface of the movable pot support 101 is significantly higher than the upper surface of the first support 51, so that the height difference between the bottom surface of the splashing oil pan and the burner is significantly higher than the designed state, that is, the splashing oil pan is lifted and away from the burner. Thus, the thermal efficiency of the stove cannot reach the ideal design goal when the splashing oil pan is heated, that is, when the user uses the movable pot support 101 supported by the first support 51 to support a small-sized cooking utensil, the flame and high-temperature flue gas generated by the burner cannot fully exchange heat with the bottom of the splashing oil pan, thereby resulting in a reduction in the thermal efficiency of the stove.

[0085] In the embodiment of the present utility model, by simultaneously providing the first support 51 and the second support 52 on the pot support 101, and making the inner edge of the upper bearing portion 521 extend above the central hole 102 and the top surface of the upper bearing portion 521 not higher than the top surface of the first support 51. Thus, when the user uses a small-sized cooking utensil, such as the above-mentioned splashing oil pan, the bottom surface of the splashing oil pan is supported by the top surface of the upper bearing portion 521 and stably suspended above the burner, and the problem that the flame and high-temperature flue gas cannot fully exchange heat with the bottom of the splashing oil pan due to the obvious elevation of the splashing oil pan can be avoided, that is, the thermal efficiency of the stove when the pot support 101 supports a small-sized cooking utensil can be improved.

[0086] Of course, in other embodiments, it may also be that the top surface of the upper bearing portion 521 is higher than the top surface of the first support 51, or the inner edge of the upper bearing portion 521 is located above the side of the central hole 102.

[0087] Please refer to Figure 5 , optionally in this embodiment, the top surface of the first support 51 and the top surface of the upper bearing portion 521 are arranged flush. Thus, when cooking utensils of different sizes are placed on the pot support 101, the height difference between their bottom surfaces and the burner can be basically kept the same, which is beneficial to maintaining the thermal efficiency of the stove at a relatively high level.

[0088] Please refer to Figure 5, in an embodiment where the second bracket 70 has an inner reinforcing flange 74, optionally, the upper supporting portion 521 extends towards the center of the central hole 102 and exceeds the inner perimeter of the second ring plate 72. Further optionally, the inner end face of the upper supporting portion 521 exceeds the inner perimeter of the inner reinforcing flange 74. That is, a projection area is formed by the positive projection of the upper supporting portion 521 towards the plane where the inner perimeter of the inner reinforcing flange 74 is located, and the inner edge of this projection area is located within the area enclosed by the inner perimeter of the inner reinforcing flange 74. In this way, the upper supporting portion 521 can also play a good supporting role for cookware and pots with a relatively small width dimension, so as to improve the adaptability of the pot bracket 101 and enhance the user experience.

[0089] Of course, in other embodiments, it may also be that the upper supporting portion 521 extends towards the center of the central hole 102 and exceeds the inner perimeter of the second ring plate 72, but does not exceed the inner perimeter of the inner reinforcing flange 74; or, the upper supporting portion 521 extends towards the center of the central hole 102, and its inner end face does not exceed the inner perimeter of the second ring plate 72.

[0090] Please refer to Figure 1 , optionally, there are multiple second supports 52, and the multiple second supports 52 are arranged at intervals along the circumferential direction of the central hole 102. In this way, the multiple second supports 52 jointly support the cookware, which can improve the placement stability of the cookware.

[0091] Optionally, the diameter of the circle that is externally tangent to the inner perimeters of the multiple second supports 52 ranges from 10 mm to 16 mm, for example, taking values of 12 mm, 13 mm, or 14 mm. That is, the minimum width of the cookware that the second support 52 can support ranges from 10 mm to 16 mm.

[0092] Please refer to Figure 1 , optionally, there are multiple first supports 51, and the multiple first supports 51 are arranged at intervals along the circumferential direction of the central hole 102. In this way, the multiple first supports 51 jointly support the cookware, which can improve the placement stability of the cookware.

[0093] Please refer to Figure 3 , in an embodiment where the top surfaces of the first support 51 and the second support 52 are flush, optionally, the first support 51 and the second support 52 are staggeredly distributed in the radial direction of the central hole 102. In this way, for large-sized cookware, both the first support 51 and the second support 52 can play a supporting role for the cookware, and the positions of the supporting actions are more evenly distributed on the bottom surface of the cookware, which is beneficial to improving the placement stability of the cookware. Of course, in other embodiments, it may also be that the first support 51 and the second support 52 are relatively distributed in the radial direction of the central hole 102.

[0094] Please refer to Figure 6, To facilitate the disassembly and cleaning of the second support 70, further, the second support 52 further includes a lower support portion 523 connected to the upper support portion 521. The lower support portion 523 is located on the lower side of the second support 70 and is detachably connected to the first support 10. In this way, the second support 52 can be detachably mounted on the first support 10 through the lower support portion 523, so as to facilitate the disassembly and installation of the second support 70, to facilitate a more comprehensive cleaning of the first support 10 and the second support 70 separately, and to avoid the problem that it is difficult to clean the dirt attached in the area with a small gap. Secondly, since the lower support portion 523 is provided on the lower side of the second support 70, the overall structure of the second support 70 and the second support 52 is more compact. It can be understood that at this time, the second support 70 is configured as a movable pot support 101. In the embodiment where the upper support 50 includes the first support 51 and the second support 52, since the first support 10 has the first support 51, the user can selectively mount the second support 70 on the first support 10 according to usage habits and needs. Of course, in other embodiments, it may also be that the lower support portion 523 is provided on the side of the second support 70.

[0095] Optionally, the lower surface of the lower support portion 523 abuts against the upper surface of the first support 10. That is, the second support 70 can be directly placed on the first support 10 through the lower support portion 523. When it is necessary to disassemble the second support 70, it can be taken from the first support 10. In this way, the structure is simple and easy to implement, and the disassembly and assembly of the second support 70 are easy. Of course, in other embodiments, it may also be that the lower support portion 523 is detachably mounted on the first support 10 by means of screwing or clamping.

[0096] Please refer to Figure 6 and Figure 8 , Further, a positioning groove 111 is provided on the upper surface of the first support 10, and at least a part of the lower support portion 523 is provided in the positioning groove 111. In this way, the positioning groove 111 can play a certain limiting role on the lower support portion 523, so that the second support 70 is placed more stably on the first support 10. Of course, in other embodiments, the positioning groove 111 may not be provided.

[0097] Optionally, at least a part of the positioning groove 111 is located on the lower side of the second ring plate 72. The lower support portion 523 extends toward the center of the central hole 102 and extends beyond the center of the upper support portion 521. In this way, the pressure from the cooking utensil received by the upper support portion 521 and the supporting force from the groove wall of the positioning groove 111 received by the lower support portion 523 can partially overlap or be adjacent in the radial direction of the central hole 102, so as to improve the placement stability of the second support 70. Of course, in other embodiments, it may also be that the lower support portion 523 extends toward the center of the central hole 102 but does not extend beyond the center of the upper support portion 521.

[0098] Please refer to Figure 8Furthermore, a plurality of reinforcing ribs 112 are convexly provided on the upper surface of the first bracket 10, and the plurality of reinforcing ribs 112 are arranged at intervals along the circumferential direction of the central hole 102, and two adjacent reinforcing ribs 112 are spaced apart to form a positioning groove 111. In this way, the structure is simple and easy to implement, and the local structural strength of the first bracket 10 can be improved by adding the reinforcing ribs 112. Of course, in other embodiments, the reinforcing ribs 112 may not be provided.

[0099] See also Figure 6 and Figure 8 Furthermore, an annular boss 113 is convexly provided on the upper surface of the first bracket 10, and the reinforcing rib 112 and the bottom surface of the positioning groove 111 are provided on the top surface of the annular boss 113. In this way, the reinforcing rib 112 is drawn on the annular boss 113, which is conducive to improving the molding yield of the first bracket 10 and can further improve the local structural strength of the first bracket 10. Of course, in other embodiments, the annular boss 113 may not be provided.

[0100] Further, the second support 52 also includes a connecting portion 522 intersecting with the upper supporting portion 521, and the connecting portion 522 is arranged on the side of the second bracket 70. Optionally, in an embodiment in which the second support 52 includes an upper supporting portion 521 and a lower supporting portion 523, the connecting portion 522 is connected between the upper supporting portion 521 and the lower supporting portion 523, that is, the lower supporting portion 523 is arranged relative to the upper supporting portion 521, and the second support 52 is arranged in a roughly U-shaped structure. In this way, the second support 52 is not provided with the second bracket 70, which is conducive to improving the structural strength and rigidity of the second bracket 70. Of course, in other embodiments, the lower end of the upper supporting portion 521 can also be provided with the second bracket 70 and directly connected to the lower supporting portion 523.

[0101] Optionally, the upper supporting portion 521, the lower supporting portion 523 and the connecting portion 522 are integrally formed. In this way, the structure is simple and easy to implement, and the assembly process of the second support 52 and the second bracket 70 can be reduced, which is conducive to improving the production efficiency of the pot bracket 101. Of course, in other embodiments, at least one of the upper supporting portion 521, the lower supporting portion 523 and the connecting portion 522 can also be separately provided.

[0102] See also Figure 6 In the embodiment where the second bracket 70 includes the first ring plate 71 and the outer reinforcing flange 73 bent downward from the outer periphery of the first ring plate 71, optionally, the upper supporting portion 521 is connected to the first ring plate 71, and the connecting portion 522 is connected to the outer reinforcing flange 73. In this way, the connection strength between the second support 52 and the second bracket 70 can be improved, and the second support 52 can also support the outer reinforcing flange 73, so that the outer reinforcing flange 73 is less likely to deform.

[0103] Optionally, the second support 52 is welded and fixed to the second bracket 70. In this way, the connection strength between the second support 52 and the second bracket 70 can be improved, and the structure is simple and easy to implement. For example, in this embodiment, the connecting portion 522 is welded and fixed to the outer reinforcing flange 73, and the upper bearing portion 521 is welded and fixed to the first ring plate 71. Of course, in other embodiments, it may also be that only the connecting portion 522 is welded and fixed to the outer reinforcing flange 73, or only the upper bearing portion 521 is welded and fixed to the first ring plate 71. It is also possible that the second support 52 is installed on the second bracket 70 by means of screwing or clamping.

[0104] Please refer to Figure 2 and Figure 5 , in an embodiment, the first bracket 10 includes a separately provided upper plate 11 and a lower plate 12, and a cavity 10a is formed between the upper plate 11 and the lower plate 12. Among them, the top of the first bracket 10 is located on the upper plate 11, that is, in the embodiment where the first bracket 10 has a smoke exhaust surface 11a, the smoke exhaust surface 11a is provided on the upper plate 11. In this way, the cavity 10a can play a certain heat storage role, so that the heat of the upper plate 11 can stay more on its own structure, which is beneficial to improving the thermal efficiency of the cooking appliance. Of course, in other embodiments, the first bracket 10 may not be provided with the cavity 10a.

[0105] To facilitate the cleaning of the exposed outer surfaces of the upper plate 11 and the lower plate 12, optionally, the upper surface of the upper plate 11 and the lower surface of the lower plate 12 are covered with an enamel layer (not shown in the drawings). That is, an enamel layer is formed on the upper surface of the upper plate 11 and the lower surface of the lower plate 12 by using the enamel process. The enamel layer is not only easy to clean and maintain, but also can improve the aesthetics of the first bracket 10. And, in the embodiment where the upper surface of the second bracket 20 also has an enamel layer, since the outer surfaces of the upper plate 11, the lower plate 12 and the second bracket 20 all have enamel layers, the overall appearance of the first bracket 10 and the second bracket 20 can be made more consistent. Of course, in other embodiments, only the upper surface or the lower surface of the upper plate 11 may be covered with an enamel layer.

[0106] It can be understood that when using the cooking appliance, the upper plate 11 is in a high-temperature heat storage state. If more heat of the upper plate 11 can be transferred to the cooking utensil in the form of heat radiation, the thermal efficiency of the cooking appliance can be further improved. Therefore, further, the enamel layer covering the upper surface of the upper plate 11 is configured as a far-infrared radiation enamel layer. In this way, through the far-infrared radiation enamel layer, more energy of the upper plate 11 can be converted into heat radiation energy and radiated to the cooking utensil. Of course, in other embodiments, ordinary enamel materials can also be used to manufacture the enamel layer.

[0107] Please refer to Figure 5 and Figure 6, Further, the pot support further includes a support plate 22 disposed in the cavity 10a, a lower support 40 disposed on the lower plate 12, and a first fastener 61. The support plate 22 is pre-fixed to the upper plate 11, the lower support 40 is pre-fixed to the lower plate 12, and then one end of the first fastener 61 passes through the lower support 40 and extends into the cavity 10a and is connected to the support plate 22, thereby assembling the upper plate 11 and the lower plate 12 into one body to form the first support 10.

[0108] Specifically and optionally, the support plate 22 is fixed to the upper plate 11 by welding, and the lower support 40 is attached to the lower plate 12 by a second fastener 62. Among them, the first fastener 61 and the second fastener 62 can be configured as bolts or rivets, etc. Of course, in other embodiments, the support plate 22 can also be fixed to the upper plate 11 by riveting or screwing, etc., or the lower support 40 can be directly fixed to the lower plate 12 by welding.

[0109] Please refer to Figure 5 and Figure 6 , Further, the pot support further includes a reflector 31 disposed in the cavity 10a. The reflector 31 reflects the heat transferred downward by the upper plate 11 back to the upper plate. In this way, the heat dissipation rate of the upper plate 11 can be reduced, and the heat can be retained on the upper plate 11 as much as possible, thereby improving the thermal efficiency of the cooker. Specifically and optionally, the middle part of the reflector 31 is sleeved on the end of the lower support 40 extending into the cavity 10a and is abutted by the support plate 22.

[0110] It is worth mentioning that in the embodiment where the outer surface of the upper plate 11 has an enamel layer, since the reflector 31 and the upper plate 11 are separately provided and are assembled into one body by the first fastener 61, rather than the form of welding the reflector 31 to the upper plate 11, the reflector 31 will not follow the upper plate 11 to perform the enameling process, and the problem that the reflector 31 turns black due to the high-temperature environmental conditions of the enameling process and the reflection performance fails can be avoided.

[0111] The present utility model also proposes a cooker, which includes the aforementioned pot support. The specific structure of the pot support refers to the above embodiments. Since this cooker adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0112] The above description is only an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
