Description

Technical Field

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

[0002] Currently, while there are many different designs for pot supports on the market, they still have significant shortcomings in practical applications. Firstly, regarding heat insulation, traditional pot supports often use simple, hollowed-out support structures, focusing on mechanical support rather than thermal management. During prolonged high-temperature cooking, the large amount of heat generated by the flame not only heats the pot but also directly affects the gas stove panel through heat radiation and conduction, penetrating downwards into the internal cavity of the gas stove. Secondly, in terms of improving combustion efficiency, existing pot support structures generally lack aerodynamic considerations. Ideal combustion requires a thorough mixing of combustion air and gas, but traditional pot supports, acting merely as static platforms, cannot effectively guide and optimize airflow around the burner. Their limited functionality hinders market competitiveness. Therefore, further improvements are needed. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a furnace frame with an energy-concentrating and heat-insulating structure.

[0004] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a furnace frame with an energy-concentrating and heat-insulating structure, including: a furnace cover and several supporting legs; The stove cover has a ring-shaped, concave, bowl-like structure. The support legs are vertically inserted and fixed to the stove cover to separate the stove cover from the stove. The stove cover has a central through hole in the middle to avoid the burner. The inner side of the furnace cover is provided with several spiral guide ribs; the burner burns at the central through hole to form a combustion flame and forms a negative pressure zone at the central through hole; the inner side of the furnace cover can reflect the heat radiation of the burner to the bottom of the pot, and the air above the outer periphery of the burner can be drawn along the spiral guide ribs of the furnace cover to the negative pressure zone of the central through hole, forming a spiral ring of secondary supplementary air for the combustion flame.

[0005] Optionally, the support feet are provided with at least three, which are evenly arranged along the circumference of the furnace cover.

[0006] Optionally, at least one of the spiral guide ribs is provided between two adjacent support feet.

[0010] Optionally, the outer edge of the furnace cover is provided with a downwardly extending anti-collision flip-down edge.

[0011] Optionally, the support legs are welded and fixed to the furnace cover.

[0012] The beneficial effects of this invention are as follows: The bowl-shaped stove lid forms a physical heat insulation barrier between the cookware and the gas stove panel, effectively preventing the direct radiation and conduction of high-temperature flames and heat from the bottom of the pot to the stove panel below. The inner side of the lid effectively reflects and concentrates the heat radiation and high-temperature flue gas diffused outward from the burner at the bottom of the cookware, significantly reducing heat loss to the surroundings, thereby improving heat utilization and achieving energy-saving effects. By setting spiral guide ribs on the inner side of the stove lid, the static stove frame is creatively transformed into a dynamic airflow device.

[0020] Example Reference Figure 1 and Figure 2 The present invention proposes a furnace frame with an energy-concentrating and heat-insulating structure, comprising: a furnace cover 10 and several supporting legs 20; The stove cover 10 has a bowl-shaped structure with a downward concave ring. The support legs 20 are vertically inserted and fixed to the stove cover 10 to separate the stove cover 10 from the stove. The stove cover 10 has a central through hole 11 in the middle to avoid the burner. The inner side of the furnace cover 10 is provided with several spiral guide ribs 12; the burner burns at the central through hole 11 to form a combustion flame and a negative pressure zone is formed at the central through hole 11; the inner side of the furnace cover 10 can reflect the heat radiation of the burner to the bottom of the pot, and the air above the outer periphery of the burner can be drawn along the spiral guide ribs 12 of the furnace cover 10 to the negative pressure zone of the central through hole 11, forming a spiral ring of secondary supplementary air for the combustion flame.

[0021] In this invention, the bowl-shaped stove lid 10 forms a physical heat insulation barrier between the cookware and the gas stove panel, effectively preventing the direct radiation and conduction of high-temperature flames and heat from the bottom of the pot to the stove panel below. The inner side of the lid effectively reflects and concentrates the heat radiation and high-temperature flue gas diffused outward from the burner at the bottom of the cookware, significantly reducing heat loss to the surroundings, thereby improving heat utilization and achieving energy-saving effects. By setting spiral guide ribs 12 on the inner side of the stove lid 10, the static stove frame is creatively transformed into a dynamic airflow device. It can utilize the negative pressure zone formed in the center of the burner to actively and smoothly draw in the surrounding air, forming a spiral-shaped upward secondary supplementary airflow. This airflow can tightly surround the flame, making the combustion air and gas mix more thoroughly, significantly improving combustion efficiency, resulting in a higher and more concentrated flame temperature, while effectively reducing the emission of harmful gases such as carbon monoxide.

[0022] In this embodiment, at least three support feet 20 are provided, evenly arranged around the circumference of the stove lid 10. The at least three evenly distributed support feet 20 can form a stable triangular (or polygonal) support structure, which makes the cookware bear the force evenly, effectively preventing the cookware from tilting or slipping during cooking and improving the safety of use.

[0023] Specifically, at least one spiral guide rib 12 is provided between two adjacent support feet 20. This ensures the integrity of the support structure and also ensures that air can be guided evenly and efficiently along the entire circumference from the outer perimeter of the furnace cover 10 to the central through hole 11, thus guaranteeing the secondary air replenishment effect.

[0024] In this embodiment, an anti-slip pad 21 is embedded in the bottom of the support foot 20. The anti-slip pad 21 embedded in the bottom of the support foot 20 increases the friction between the stove rack and the stove panel, preventing the stove rack from sliding when the user operates the cookware and improving stability. On the other hand, the soft anti-slip pad 21 (such as a rubber pad) can prevent the hard support foot 20 from directly scratching and damaging the delicate glass panel or enamel surface of the gas stove, thus playing a protective role.

[0025] In this embodiment, the spiral guide rib 12 has an arc-shaped transition at both ends and a raised center. The arc-shaped transition at both ends of the spiral guide rib 12 can significantly reduce airflow resistance, making airflow smoother and avoiding the formation of vortices that affect the air supply efficiency; the raised center structure can accurately guide the airflow to converge towards the negative pressure zone of the central through hole 11, enhancing the directionality of the airflow and ensuring that the secondary air supply accurately acts on the periphery of the combustion flame; in addition, this structure can also improve the mechanical strength of the guide rib and ensure the stability of the airflow effect during long-term use.

[0026] In this embodiment, the outer edge of the central through hole 11 extends upward at an angle or in an arc shape, forming a recessed liquid collection groove 13 with the main body of the stove cover 10. The liquid collection groove 13 formed by the inclined or arc-shaped extension of the outer edge of the central through hole 11 can effectively collect soup and oil spilled from the pot, preventing them from flowing into the internal cavity of the gas stove, preventing internal igniters, wiring and other parts from malfunctioning due to oil corrosion or liquid immersion, and ensuring the service life of the gas stove.

[0027] In this embodiment, the outer edge of the furnace cover 10 is provided with a downwardly extending anti-collision flange 14. The downwardly extending anti-collision flange 14 on the outer edge of the furnace cover 10 firstly strengthens the structure and prevents the edge from curling and deforming; secondly, it forms a smooth transition, which can effectively prevent the user's hand or arm from being scratched by the sharp edge during operation, thereby improving the safety of the product and the user experience.

[0028] In this embodiment, the support leg 20 is welded and fixed to the furnace cover 10. The connection strength is high, and the structure is stable and reliable, ensuring that the furnace frame will not loosen or fall apart under long-term high-temperature environment and heavy load-bearing use, thus guaranteeing the durability of the product.

[0029] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
