[0039] This embodiment provides an energy-gathering pan rack having a flow-guiding structure, which prolongs the residence time of high-temperature smoke from combustion in the energy-gathering pan rack, thereby improving the combustion thermal efficiency of the gas stove.

[0040] like Figure 1 and Figure 2 As shown, the energy-gathering plate pot support comprises an energy-gathering plate body 1 and a support 2, wherein an avoidance through hole 11 is provided on the energy-gathering plate body 1, and the avoidance through hole 11 is used to avoid the burner 100, so that the energy-gathering plate body 1 is sleeved on the outer periphery of the burner 100. The inner diameter of the avoidance through hole 11 is larger than the outer diameter of the burner 100, ensuring sufficient assembly clearance and ensuring the entry and supply of secondary air required during combustion, so as to make the combustion more complete and improve the overall combustion effect.

[0041] The energy-gathering disk body 1 is a concave annular disk, and its outer edge is relatively higher than the inner edge. This structural setting is conducive to the gathering of high-temperature combustion flue gas, strengthening the heat exchange intensity with the bottom of the pot, reducing the loss of high-temperature combustion flue gas to the surrounding radiation heat dissipation, and effectively improving the thermal energy utilization rate, thereby improving the thermal efficiency of combustion.

[0042] The support 2 is arranged on the energy concentrating plate body 1, and the support 2 is used to support the cooker. The support 2 is provided with a guide portion 23, and the guide portion 23 is configured to allow high-temperature smoke to pass from bottom to top.

[0043] The guide portion 23 forms a high-temperature flue gas channel. When the high-temperature flue gas generated during the combustion process flows in the energy-gathering disk body 1, the bracket 2 performs layered guidance on the high-temperature flue gas. Part of the high-temperature flue gas flows from the upper end of the bracket 2, and the other part of the high-temperature flue gas flows from the lower end of the bracket 2 and flows vertically from bottom to top along the high-temperature flue gas guide channel, while impacting the high-temperature flue gas flowing at the upper end of the bracket 2, causing disturbance to form a turbulent flow, thereby blocking and delaying the flow rate of the high-temperature flue gas flowing in the upper part, thereby extending the residence time of the high-temperature flue gas in the energy-gathering disk body 1, that is, extending the heat exchange time between the high-temperature flue gas and the bottom of the pot, which is beneficial to the gathering of combustion heat energy, and at the same time guiding the flow upward to the bottom of the pot, increasing the impact strength of the high-temperature flue gas on the bottom of the pot, enhancing the heat exchange effect between the high-temperature flue gas and the bottom of the pot, and also contributing to the re-combustion of the high-temperature flue gas, making the combustion more complete, thereby improving the utilization rate of the combustion heat energy, and further improving the overall combustion thermal efficiency.

[0044] The bracket 2 is provided with a plurality of guide portions 23, and the plurality of guide portions 23 are evenly arranged on the bracket 2 along the circumferential direction. By providing a plurality of guide portions 23 on the bracket 2, the guide requirements for high-temperature flue gas with a large amount of smoke can be met. The plurality of guide portions 23 are evenly arranged, which can improve the uniformity of the guide of the bracket 2 to the high-temperature flue gas, reduce the impact strength of the high-temperature flue gas on the bracket 2, and improve the structural stability.

[0045] The flow guide portion 23 may be, but is not limited to, a flow guide hole, specifically a circular hole. The result is simple and easy to process. The aperture of the flow guide hole can be designed according to actual conditions, and is not specifically limited here. The number of the flow guide holes can be designed according to actual conditions. In this embodiment, 20 flow guide holes are provided.

[0046] Combination Figure 3 As shown, the energy concentrating disk body 1 includes a chassis portion 10, a support portion 12 and a retaining portion 13 connected in sequence in a radial direction, the center of the chassis portion 10 is provided with the above-mentioned avoidance through hole 11, the retaining portion 13 is arranged in the vertical direction, the bracket 2 is abutted against the support portion 12 and located on the inner side of the retaining portion 13, and the support portion 12 and the retaining portion 13 are used to place and radially limit the bracket 2. The support portion 12 can be, but not limited to, an annular step structure, and the retaining portion 13 can be, but not limited to, a vertically arranged ring structure.

[0047] Specifically, the bracket 2 includes a bottom ring 21 and a plurality of support members 22. The bottom ring 21 is annular in shape. The plurality of support members 22 are arranged on the bottom ring 21 along the circumferential direction. The support members 22 are in contact with the bottom of the pot to support the pot. The pot is placed on the plurality of support members 22, which is stable and reliable. A flow guide 23 is arranged on the bottom ring 21, and the bottom ring 21 is in contact with the support member 12.

[0048] The above-mentioned structural arrangement enables the bracket 2 to separate the high-temperature flue gas from the combustion in the energy-gathering disk body 1 into two parts, the upper part and the lower part, for diversion. That is to say, when the high-temperature flue gas generated during the combustion of the burner 100 flows in the energy-gathering disk body 1, the bottom ring 21 diverts it in layers, with one part flowing from the upper end of the bottom ring 21 and the other part flowing from the lower end of the bottom ring 21. The high-temperature flue gas flowing from the lower end of the bottom ring 21 flows vertically upward along the guide portion 23, and at the same time impacts the high-temperature flue gas flowing at the upper end of the bottom ring 21, thereby generating The disturbance is generated to form a turbulent flow, thereby blocking and slowing down the flow speed of the high-temperature flue gas at the upper end of the bottom circle 21, prolonging the residence time of the burning high-temperature flue gas in the energy-gathering disk body 1, that is, prolonging the heat exchange time between the high-temperature flue gas and the bottom of the pot, and at the same time guiding the flow upward to the bottom of the pot, increasing the impact strength of the burning high-temperature flue gas on the bottom of the pot, greatly enhancing the heat exchange effect between the burning high-temperature flue gas and the bottom of the pot, and also contributing to the re-combustion of the high-temperature flue gas, making the combustion more complete, thereby improving the combustion thermal efficiency of the gas stove.

[0049] The support member 22 is arranged on the upper surface of the bottom ring 21, and the outer diameter of the support member 22 is not greater than the outer diameter of the bottom ring 21. The "outer diameter of the support member 22" mentioned here should be understood as the outer diameter of the circular ring structure composed of all the support members 22. This structural arrangement makes the support member 22 not protrude from the bottom ring 21 in the radial direction, avoiding the bottom ring 21 from contacting the energy collecting disk body 1, thereby reducing the heat loss caused by heat conduction.

[0050] In this embodiment, if Figure 4 As shown, the outer diameter of the bottom ring 21 is smaller than the inner diameter of the enclosure 13. Under this structure, the bottom ring 21 does not directly contact the enclosure 13, reducing the heat loss caused by heat conduction. There is an appropriate assembly gap between the bracket 2 and the inner wall of the enclosure 13, which facilitates the placement and radial positioning of the bracket 2. Such a structural setting not only ensures that the bracket 2 is relatively stable, but also avoids direct contact between the bracket 2 and the outside air, reduces the spillage of heat energy, and allows the combustion heat energy absorbed by the bracket 2 to be conducted to the bottom of the pot more, reducing heat loss and improving the utilization rate of heat energy.

[0051] The upper end surface of the support member 22 is higher than the upper end surface of the enclosure 13. This structure can ensure the reasonable discharge of smoke, achieve the balance of combustion conditions, and improve the overall combustion effect.

[0052] In order to make the flow diversion of the burning high-temperature flue gas more effective, realize the enhancement of the turbulence and impact strength formed by the burning high-temperature flue gas at the bottom of the pot, and at the same time delay the flow rate of the high-temperature flue gas, that is, extend the residence time of the high-temperature flue gas at the bottom of the pot, further strengthen the heat exchange effect between the burning high-temperature flue gas and the bottom of the pot, improve the thermal energy utilization rate, and also to facilitate the re-combustion of the high-temperature flue gas, make the combustion more complete, thereby improving the combustion thermal efficiency. The radial width of the bottom ring 21 in this embodiment ranges from 8mm to 17mm, for example, it can be 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm or 17mm, which can be selected according to actual conditions.

[0053] The radial distance between the outer diameter of the bottom ring 21 and the inner diameter of the surrounding portion 13 ranges from 3 mm to 4.5 mm, for example, 3 mm, 3.5 mm, 4 mm or 4.5 mm, which can be selected according to actual conditions.

[0054] In addition, the upper end surface of the bottom ring 21 is lower than the upper end of the enclosure 13, and the height difference ranges from 1mm to 3mm, for example, 1mm, 2mm or 3mm. Such a setting can play a certain role in blocking and guiding the combustion high-temperature flue gas, slowing down the flow rate of the high-temperature flue gas. The inner diameter of the bottom ring 21 is smaller than the inner diameter of the support part 12. Ensure that the placement of the bracket 2 is relatively stable, reduce the contact area between the bottom ring 21 and the support part 12, and reduce the heat conduction loss.

[0055] In this embodiment, at least three support members 22 are provided. The support members 22 and the bottom ring 21 are welded and assembled structures, and can also be integrally cast structures. At least three support members 22 are evenly arranged at equal intervals along the circumferential direction to support the cooking pot. In this embodiment, four support members 22 are provided.

[0056] The energy collecting pan support can be a single-layer, double-layer or multi-layer structure. The energy collecting pan support in this embodiment is a double-layer structure, that is, the energy collecting pan support also includes a bottom cover shell 4 connected to the energy collecting pan body 1, and a heat insulation cavity 200 is formed between the bottom cover shell 4 and the energy collecting pan body 1. The bottom cover shell 4 is an annular deep concave disc as a whole, and a through hole is opened in the middle. The inner diameter of the through hole is larger than the outer diameter of the burner 100, and the outer edge of the bottom cover shell 4 is higher than the inner hole edge. The energy collecting pan body 1 is located above the bottom cover shell 4, and the inner hole edge of the energy collecting pan body 1 is in contact with the inner hole edge of the bottom cover shell 4, and the outer edge of the energy collecting pan body 1 is also in contact with the outer edge of the bottom cover shell 4. The above-mentioned joints can be welded, and the rest of the parts are arranged in air, so that a heat insulation cavity 200 is formed between the bottom cover 4 and the energy collecting plate body 1. The heat insulation cavity 200 contains air to utilize the poor heat conductivity of air. The heat insulation cavity 200 can play a good heat insulation effect, reduce heat loss, and improve the utilization rate of heat energy. The energy collecting plate body 1 is close to the combustion flame, and its temperature rises faster, so that the heat energy of the high-temperature flue gas gathered in the energy collecting plate body 1 is higher, thereby enhancing the heat exchange effect between the high-temperature flue gas and the bottom of the pot, and improving the combustion thermal efficiency.

[0057] The energy-gathering pan support in the present embodiment is circular, and may also be square, square-round, elliptical, polygonal, etc., and may be specifically configured according to actual conditions.

[0058] The energy collecting disk body 1 and the bracket 2 in this embodiment are arranged in a detachable connection form, which is convenient for cleaning, and can realize the universalization and scale of the energy collecting disk body 1, improve production efficiency and reduce costs. The bracket 2 can be arranged in a variety of styles to meet the needs of different consumers.

[0059] At least three feet 3 are provided on the bottom of the energy collecting plate body 1. The feet 3 are provided to form a secondary air inlet channel between the bottom of the energy collecting plate body 1 and the cooker panel, thereby ensuring the supply of secondary air required for combustion to achieve more complete combustion.

[0060] In order to reduce the heat loss and abrasion caused by the direct contact between the foot 3 and the cooker panel or the liquid tray, a non-metallic pad is optionally provided at the bottom of the foot 3. 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.

[0061] The energy-gathering pan rack provided in this embodiment realizes the effective gathering of high-temperature flue gas, reduces the loss of heat radiation from high-temperature flue gas to the surroundings, and improves the utilization rate of combustion heat energy. On the one hand, it effectively slows down the flow rate of high-temperature flue gas, prolongs the residence time of high-temperature flue gas at the bottom of the pot, that is, prolongs the heat energy exchange time between high-temperature flue gas and the bottom of the pot, and enhances the heat exchange intensity between high-temperature flue gas and the bottom of the pot; on the other hand, it realizes the enhancement of the turbulence and impact intensity formed by high-temperature flue gas at the bottom of the pot, further strengthens the heat exchange effect between high-temperature flue gas and the bottom of the pot, thereby improving the combustion thermal efficiency; on the other hand, it also helps the re-combustion of high-temperature flue gas, makes the combustion more complete, and reduces the generation of waste gases such as CO.

[0062] This embodiment also provides a gas cooker, which includes the aforementioned energy-gathering pan rack. Since the gas cooker includes the aforementioned energy-gathering pan rack, the technical advantages and effects that the gas cooker can achieve also include the technical advantages and effects that the energy-gathering pan rack can achieve, which will not be repeated here.

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.
