[0038] like Figures 1 to 3 As shown, this embodiment provides a pot rack 100, which is placed on the panel 300 of the gas cooker and sleeved on the outside of the burner 200 to support the pot. The pot rack 100 includes an energy collecting plate 1 and a bracket. The energy collecting plate 1 is a concave annular plate body, on which an avoidance through hole 11 is opened. The avoidance through hole 11 is used to avoid the burner 200, so that the energy collecting plate 1 is sleeved on the outer periphery of the burner 200. The inner diameter of the avoidance through hole 11 is larger than the outer diameter of the burner 200, ensuring sufficient assembly clearance and ensuring the entry and supply of secondary air required during combustion, so that the combustion is more complete and the overall combustion effect is improved.
[0039] The energy-gathering disk 1 is a concave annular disk with an outer edge relatively higher than the inner edge. This structural setting is conducive to the gathering of high-temperature flue gas during combustion, strengthening the heat exchange intensity with the bottom of the pot, reducing the loss of high-temperature flue gas from radiating heat to the surrounding area, and effectively improving the utilization rate of thermal energy, thereby improving the thermal efficiency of combustion.
[0040] The bracket is used to support the cookware, and the bracket is arranged on the energy gathering disk 1. The bracket and the energy gathering disk 1 are an integrated structure. The bracket includes at least three flow-blocking baffles 2, and the at least three flow-blocking baffles 2 are radially and evenly distributed on the upper surface of the energy gathering disk 1, and the flow-blocking baffles 2 extend from the avoidance through hole 11 to the outer edge of the energy gathering disk 1, and the flow-blocking baffles 2 have at least one arc-shaped flow-blocking surface.
[0041] During the cooking process of the gas stove, when the high-temperature smoke radiates from the center of the energy-gathering disk 1 to the outside, the arc-shaped flow-blocking surface of the flow-blocking baffle 2 can slow down the diffusion speed of the high-temperature smoke, thereby increasing the residence time in the disk and prolonging the heat exchange time between the high-temperature smoke and the bottom of the pot; when the high-temperature smoke flows to the edge of the energy-gathering disk 1, it will also be blocked by the outer edge of the energy-gathering disk 1, so that the high-temperature smoke gathers in the pot rack 100, forming a high-temperature thermal field, enhancing the heat exchange intensity with the bottom of the pot, reducing the loss of heat dissipation from the burning high-temperature smoke to the surrounding radiation, and effectively improving the utilization rate of heat energy, thereby improving the combustion thermal efficiency. In addition, the high-temperature smoke will form a vortex near the arc-shaped flow-blocking surface and rise along the height direction of the flow-blocking baffle 2, increasing the impact strength of the high-temperature smoke on the bottom of the pot, thereby enhancing the heat exchange effect between the high-temperature smoke and the bottom of the pot and improving the thermal efficiency.
[0042] In this embodiment, the bracket and the energy collecting plate 1 are an integral casting structure. Compared with the split structure in the prior art, the integral molding process of the bracket and the energy collecting plate 1 is simple, the processing cost is low, and it is easy to clean, eliminating the steps of assembling and using the two, and improving the support stability of the cookware.
[0043] The bracket is made of heat-conductive material, so that the contact surface between the bracket and the pot can achieve heat transfer and conduction, further improving thermal efficiency.
[0044] The flow blocking piece 2 is S-shaped along the radial direction of the energy concentrating disk 1, that is, the flow blocking piece 2 is an S-shaped strip piece, including two arc-shaped flow blocking surfaces. Of course, it can also be a C-shaped or a wavy strip piece with more than two arc-shaped flow blocking surfaces, as long as it is a strip piece with at least one arc-shaped flow blocking surface.
[0045] On the flow path where the high-temperature flue gas radiates radially from the inside to the outside, the arc-shaped flow-blocking surface can be an arc-shaped concave surface or an arc-shaped convex surface. Taking the S-shaped flow-blocking baffle 2 as an example, on a flow path, the flow-blocking baffle 2 includes an arc-shaped concave surface and an arc-shaped convex surface. When the high-temperature flue gas radiates outward, it will first be retained in the arc-shaped concave surface close to the inner side of the pot rack 100, or be blocked by the arc-shaped convex surface, thereby slowing down the diffusion of the high-temperature flue gas; when the flue gas diffuses outward again, it will be blocked by the next arc-shaped convex surface or buffered by the arc-shaped concave surface, so that the high-temperature flue gas continues to gather heat inside the pot rack 100; finally, the high-temperature flue gas diffusing outward will also be blocked by the outer edge of the energy-gathering disk 1 to slow down the speed of outward radiation. Therefore, when the high-temperature flue gas radiates outward, it will be blocked multiple times, thereby forming a high-temperature thermal field between the pot rack 100 and the bottom of the pot, thereby improving thermal efficiency.
[0046] The number of the flow blocking baffles 2 can be designed according to actual conditions. In this embodiment, eight flow blocking baffles 2 are provided.
[0047] Along the radial direction of the energy-gathering disk 1 , the height of the flow-blocking baffle 2 changes from high to low from outside to inside, which is beneficial to preventing heat from diffusing out of the pot rack 100 and improving thermal efficiency.
[0048] The height of the outermost side of the flow blocking baffle 2 is higher than the upper end surface of the energy gathering disk 1. This structure can ensure the reasonable discharge of smoke, achieve the balance of combustion conditions, and improve the overall combustion effect.
[0049] The top surface of the flow blocking baffle 2 includes a support plane 21 for supporting the pot, and the support plane 21 is connected to the top surface located inside thereof in an arc shape. The bracket includes at least three flow blocking baffles 2, and thus has at least three support planes 21, which can achieve stable support for the pot.
[0050] In order to prevent the pan from slipping and improve the support stability of the pan rack 100 on the pan, an anti-slip portion is provided on the support plane 21. The anti-slip portion may be a serrated structure processed on the support plane 21. Of course, the anti-slip portion may also be an anti-slip layer made of a high temperature resistant material fixed on the support plane 21, or a convex structure arranged at intervals on the support plane 21, or other anti-slip structures, as long as they can prevent the pan from slipping.
[0051] The pot stand 100 in this embodiment further includes an auxiliary ring 3 for matching small diameter pots. The auxiliary ring 3 is arranged on the bracket. The diameter of the auxiliary ring 3 is larger than the diameter of the avoidance through hole 11 and smaller than the diameter of the energy gathering plate 1. When a small size pot is needed, the pot can be directly placed on the auxiliary ring 3. By providing the auxiliary ring 3, the adaptability of the pot stand 100 to the pot can be increased, thereby satisfying the use of pots of different sizes.
[0052] The bracket is provided with a limiting step, and the step surface of the limiting step is used to place the auxiliary ring 3. Each flow blocking baffle 2 is provided with a sub-limiting step, and at least three sub-limiting steps together constitute the limiting step of the bracket. The auxiliary ring 3 and the bracket in this embodiment are set as a split structure, and the auxiliary ring 3 can be placed when not in use, meeting the different usage requirements of customers.
[0053] In another feasible implementation manner, the auxiliary ring 3 and the bracket are an integrally formed structure, which is convenient for processing and manufacturing.
[0054] The pot rack 100 in this embodiment is circular, and may also be square, square-round, elliptical, polygonal, etc., and may be specifically configured according to actual conditions.
[0055] The bottom surface of the energy collecting plate 1 is provided with at least three feet, and a secondary air inlet channel is formed between the bottom surface of the energy collecting plate 1 and the cooker panel 300 by providing the feet, thereby ensuring the supply of secondary air required for combustion to achieve more complete combustion.
[0056] In order to reduce the occurrence of heat loss and abrasion caused by direct contact between the foot and the cooker panel 300 or the liquid tray, a non-metallic pad is optionally provided at the bottom of the foot. The non-metallic pad can be made of heat-resistant silicone rubber, fluororubber, polytetrafluoroethylene and other materials, which can reduce heat conduction loss and buffer, and avoid abrasion. At the same time, the non-metallic pad can also play an anti-skid role to prevent the pot from slipping.
[0057] This embodiment also provides a gas cooker, which includes the aforementioned pot rack 100. Since the gas cooker includes the aforementioned pot rack 100, the technical advantages and effects that can be achieved by the gas cooker also include the technical advantages and effects that can be achieved by the pot rack 100, which will not be repeated here.
[0058] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
