Description

Technical Field

[0001] This utility model relates to the field of stove accessories technology, and in particular to a stove energy-concentrating support structure. Background Technology

[0002] With the continuous development of modern kitchen stove technology, combustion efficiency and energy utilization rate have become important indicators for measuring stove performance. Traditional stoves typically employ energy-concentrating support structures during installation to improve thermal efficiency, such as by installing a waterproof tray and support frame around the burner to reduce heat loss to the surrounding environment. However, existing technologies generally suffer from the following technical shortcomings:

[0003] 1. Insufficient Air Supply: When the cooktop is embedded in the countertop, the increased seal between the cooktop panel and the countertop makes it difficult for outside air to effectively enter the cooktop. Traditional energy-concentrating cooktop brackets typically have a closed or simply perforated waterproof tray design, lacking an optimized structure for airflow, resulting in an imbalance in the air-gas mixture at the injector. Incomplete combustion not only produces harmful substances such as carbon monoxide and nitrogen oxides but also significantly reduces thermal efficiency, leading to energy waste.

[0004] 2. The contradiction between heat insulation and heat dissipation: Although existing energy-concentrating supports reduce heat loss through insulation structures, their overly enclosed design further hinders natural air convection. For example, some solutions use solid insulation layers or dense support structures, which can temporarily improve thermal stability, but cause the burner to be in a state of oxygen deficiency for a long time, exacerbating the problem of incomplete combustion.

[0005] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides an energy-concentrating support structure that can maintain high-efficiency heat insulation performance while ensuring smooth airflow into the stove, thereby improving thermal efficiency while reducing pollutant emissions and meeting the needs of energy conservation and environmental protection.

[0007] This utility model is achieved through the following technical solution:

[0008] A cooktop energy-concentrating support structure includes a waterproof tray that can be connected to the cooktop panel and a support frame that is connected to the waterproof tray and can support the cookware. The waterproof tray is provided with burner clearance holes, and a heat insulation part is provided between the waterproof tray and the support frame to reduce heat loss. The waterproof tray and / or the support frame are also provided with air passages that allow air to enter the cooktop. The air passages have a first air port located on the upper side of the panel and a second air port located on the lower side of the panel.

[0009] As described above, in a stove energy-concentrating bracket structure, the heat insulation part includes a boss surrounding the clearance hole.

[0010] In the stove energy-concentrating support structure described above, at least one first air inlet of the gas passage is located at the upper end of the boss.

[0011] As described above, a stove energy-concentrating support structure is provided on the support frame to restrict foreign objects from entering the air passage. A first air intake gap communicating with a first air port is provided between the cover and the boss, or an air intake port communicating with a first air port is provided on the cover.

[0012] As described above, in a stove energy-concentrating support structure, the protrusion is provided with an open heat insulation cavity at the bottom, and the gas passage is connected to the heat insulation cavity.

[0013] As described above, in a stove energy-concentrating bracket structure, the protrusion is provided with a notch for easy cleaning of the waterproof tray, and the bottom of the notch is flush with the upper surface of the waterproof tray.

[0014] As described above, a stove energy-concentrating support structure has a stop block on the support frame for covering the gap.

[0015] As described above, in a stove energy-concentrating support structure, a second air intake gap is provided between the stop block and the boss to allow air to enter the burner.

[0016] As described above, in a stove energy-concentrating bracket structure, the waterproof tray and the support frame are separate structures, the bosses form a slot, and the support frame is provided with a plug-in part that plugs into the slot.

[0017] As described above, a stove energy-concentrating bracket structure is provided with a plurality of support blocks for supporting the cookware on the support frame, and the support frame is provided with insertion holes, and the support blocks are provided with pins that can be inserted into the insertion holes.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This product utilizes an air duct structure on a waterproof tray and / or support frame to create a stable airflow path while ensuring heat insulation and energy concentration. External air can directly enter the injector area through the air duct, significantly improving the gas-air mixture ratio, promoting more complete combustion, increasing combustion efficiency, reducing emissions of harmful gases such as carbon monoxide and nitrogen oxides, and simultaneously lowering gas consumption, thus achieving energy conservation and environmental protection.

[0020] The insulation between the waterproof tray and the support frame uses insulating material or a hollow insulating structure to effectively block heat transfer to the bottom of the stove, reducing heat loss and increasing heat concentration. The gas duct design works in conjunction with the insulation to avoid oxygen deficiency in the burner caused by excessive sealing, achieving the effect of heat insulation without blocking gas flow, balancing thermal efficiency and combustion safety.

[0021] The first gas inlet is located on the upper side of the panel, away from countertop obstructions and cooking spill paths, preventing blockage by oil or liquids and ensuring a stable gas supply over a long period. The burner clearance hole is staggered from the gas duct position to prevent the flame from directly scorching the gas duct outlet and extend the lifespan of the gas duct structure.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1 to 7 The stove energy-concentrating support structure shown includes a waterproof tray 1 that can be connected to the stove panel and a support frame 2 that is connected to the waterproof tray 1 and can support the cookware. The waterproof tray 1 is provided with a burner avoidance hole 10. A heat insulation part 3 for reducing heat loss is provided between the waterproof tray 1 and the support frame 2. The waterproof tray 1 and / or the support frame 2 are also provided with an air passage 4 that allows air to enter the stove. The air passage 4 has a first air port located on the upper side of the panel and a second air port located on the lower side of the panel.

[0032] This product utilizes the air duct 4 structure design on the waterproof tray 1 and / or support frame 2 to effectively block heat loss and increase the concentration of the heat field in the heat insulation section. At the same time, it forms a stable airflow channel from the first air port on the upper side of the panel to the second air port on the lower side, ensuring that external air bypasses the sealing area and directly reaches the injector tube. This optimizes the gas mixing ratio, making combustion more complete and significantly reducing carbon monoxide and nitrogen oxide emissions and gas consumption. The first air port of the air duct 4 is far away from the tabletop obstruction and overflow path. Combined with the staggered layout of the avoidance hole 10 and the air duct 4, it avoids blockage and prevents flame burning, taking into account high efficiency, energy saving, environmental protection, safety and structural durability.

[0033] In some embodiments, the heat insulation part 3 includes a boss 31 surrounding the clearance hole 10 to form an annular heat insulation barrier that directly blocks the heat radiation from the flame area to the outside. The boss 31 is integrally formed or separately assembled on the waterproof plate 1 to enhance the deformation resistance of the edge of the clearance hole 10 and reduce the risk of material fatigue caused by high temperature.

[0034] Furthermore, at least one first air inlet of the air passage 4 is located at the upper end of the boss 31. The height of the air inlet 41 is higher than the surface of the countertop and the waterproof tray 1, completely avoiding the range of cooking spills and oil splashes, ensuring that the air passage is unobstructed for a long time; by integrating the air inlet 41 using the height space of the boss 31 itself, there is no need to add additional complex flow guiding components, simplifying the processing technology and reducing manufacturing costs.

[0035] Furthermore, the support frame 2 is provided with a cover 21 to restrict foreign objects from entering the air passage 4. A first air intake gap 23 communicating with the first air inlet is provided between the cover 21 and the boss 31, or an air inlet 22 communicating with the first air inlet is provided on the cover 21. The cover 21 covers the upper side of the first air inlet 41 of the air passage 4, effectively further intercepting foreign objects such as oil stains and food scraps from entering the interior of the air passage 4, avoiding the risk of airway blockage. As an extension of the support frame 2, the cover 21 provides physical protection for the boss 31 and the first air inlet 41, reducing the risk of mechanical damage caused by external impacts or movement of the cookware. The cover 21 is integrally formed with the support frame 2 or is detachably connected, facilitating cleaning, maintenance, or partial replacement; the air intake structure is hidden inside the cover 21, maintaining the simple appearance of the stove and avoiding exposed air inlets from affecting visual aesthetics.

[0036] In some embodiments, the boss 31 is provided with a heat insulation cavity 310 with an open lower part. The air passage 4 is connected to the heat insulation cavity 310. The heat insulation cavity 310 is open at the lower part to form an air heat insulation layer. The low thermal conductivity of air is used to block the high temperature of the flame from directly radiating to the outside. Furthermore, the cavity can be filled with high temperature resistant heat insulation material to form a composite heat insulation barrier of air and material, which significantly reduces the heat loss rate.

[0037] After the air passage 4 connects to the heat insulation cavity 310, external air can flow along the inner wall of the heat insulation cavity 310 before entering the air passage, absorbing the residual heat accumulated in the cavity and forming a preheated airflow. The preheated air mixes with the fuel gas at a faster speed, resulting in a more complete combustion reaction and reducing the risk of flameout caused by local low temperatures. The cavity structure of the heat insulation cavity 310 has a capacity expansion and flow stabilization effect on the airflow, suppressing intake pulsations caused by combustion fluctuations and ensuring the stability of the air-fuel mixing process.

[0038] In some embodiments, the boss 31 is provided with a notch 5 for easy cleaning of the waterproof tray 1, the bottom of which is flush with the upper surface of the waterproof tray 1. The flush bottom of the notch 5 with the surface of the waterproof tray 1 forms a continuous planar transition, allowing liquid or solid residue to be wiped away along the notch 5, preventing dirt from accumulating at the base of the boss 31 and completely eliminating the cleaning blind spot at the traditional boss-waterproof tray joint. Users can directly use a cloth or scraper to push from the surface of the waterproof tray 1 to the area of ​​the notch 5, achieving deep cleaning without disassembling parts, significantly reducing the difficulty of daily maintenance. The notch 5 provides deformation compensation space for the boss 31; when the boss 31 expands due to heat at high temperatures, the notch 5 can absorb some stress, preventing structural cracking or sealing failure caused by thermal deformation. Simultaneously, the notch 5 can also serve as an air intake channel to provide air to the burner.

[0039] Furthermore, the support frame 2 is equipped with a stop block 6 to cover the notch 5. The stop block 6 covers the outside of the notch 5, preventing splattered oil, soup, or small foreign objects from entering the connection area between the waterproof tray 1 and the boss 31 during cooking. The stop block 6 visually shields the notch 5, maintaining the overall integrity and simplicity of the energy-concentrating bracket's appearance and preventing exposed notches from compromising the aesthetic design of the stove. At the same time, the cooperation between the stop block 6 and the notch 5 also serves to position the appliance during installation.

[0040] Furthermore, a second air intake gap 61 is provided between the baffle 6 and the boss 31 to allow air to enter the burner. This provides sufficient air to the burner.

[0041] In some embodiments, the waterproof tray 1 and the support frame 2 can be an integral structure. Of course, the waterproof tray 1 and the support frame 2 can also be separate structures. When it is a separate structure, the boss 31 forms a slot 7, and the support frame 2 is provided with a plug-in part 24 that plugs into the slot 7, so that the waterproof tray 1 and the support frame 2 can be connected together.

[0042] In some embodiments, the support frame 2 is provided with a plurality of support blocks 25 for supporting cookware. Each support block 25 has a plurality of grooves to reduce the contact area with the cookware and reduce localized heat accumulation. In one embodiment, the support block 25 and the support frame 2 are an integral structure. In another embodiment, the support frame 2 is provided with a insertion hole 26, and the support block 25 is provided with a pin 251 that can be inserted into the insertion hole 26. The support block 25 is connected to the support frame 2 by inserting the pin 251 into the insertion hole 26. Furthermore, the boss 31 has a corresponding insertion hole for inserting the pin 251.
