Description

Technical Field

[0001] The invention relates to a gas furnace accessory, in particular to a high-efficiency energy-gathering plate for a gas furnace. Background Art

[0002] As the core equipment in modern family kitchens, gas stoves have been widely used due to their advantages such as fast heating speed, adjustable firepower, and convenience of use. However, with the increasing awareness of energy conservation and environmental protection, how to further improve the thermal efficiency of gas stoves has become an important issue of common concern to users and manufacturers.

[0003] In the design of traditional gas stoves, the pot is usually directly supported by the stove frame. The heat generated by the gas flame through the burner directly acts on the bottom of the pot, causing the pot to heat up. However, this traditional design has a significant problem of low heat utilization efficiency. Specifically, in existing gas stoves, the bottom of the pot is in contact with the stove frame, and the flame directly contacts a part of the bottom of the pot after being ejected from the burner, and a large amount of heat is radiated and dissipated outward through the periphery of the bottom of the pot.

[0004] This structural design prevents heat from being effectively concentrated at the bottom of the pot, resulting in uneven heating of the pot. During cooking, the flame forms a high-temperature area at the periphery of the pot, while the temperature in the center of the pot is relatively low, resulting in low heating efficiency. Since the heat cannot be fully concentrated at the bottom of the pot, part of the heat energy cannot be effectively transferred to the food in the pot, thus reducing the actual utilization efficiency of the gas.

[0005] In addition, the traditional stove rack design is usually a flat or slightly concave structure, which cannot form an effective energy gathering effect. The space between the pot and the flame is large. When the flame burns, it not only directly heats the bottom of the pot, but also causes the heat to diffuse outward along the periphery of the pot. This outward radiated heat not only wastes gas resources, but may also cause the kitchen environment temperature to rise, affecting the user's cooking experience. Therefore, it is necessary to make further improvements. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency energy-gathering plate for a gas stove that is simple in structure, easy to use, can effectively gather heat at the bottom of a pot, improve the thermal efficiency of the gas stove, and reduce energy waste.

[0007] The objective of the present invention is achieved in the following manner: a high-efficiency energy-gathering plate for a gas furnace, comprising a conical plate which is larger at the top and smaller at the bottom, the bottom of the conical plate having a lower flange extending toward the center of the circle, the top of the conical plate having an upper panel extending outward, the surface of the upper panel being provided with a plurality of upper convex rings bulging upward, a downwardly concave lower convex ring being formed between the inner and outer upper convex rings, the plurality of upper convex rings and the lower convex rings forming a wavy plate surface of the upper panel.

[0008] Furthermore: a plurality of lower legs extend downward from the bottom of the upper panel, and a plurality of upper furnace ears extend upward from the top of the upper panel.

[0009] Furthermore: the upper panel is in a conical disc shape with a high outer side and a low inner side.

[0010] Furthermore: the upper end surface of the upper furnace ear is provided with a plurality of stepped surfaces which are higher outside and lower inside.

[0011] Furthermore: in the step surface, the lowest level is a sloped surface which is higher outside and lower inside.

[0012] Furthermore: the conical disk and the upper panel are integrally cast.

[0013] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0014] 2. The corrugated structure of the upper panel can effectively guide the high-temperature smoke generated by combustion to diffuse along the corrugations through the undulations on its surface. The corrugated upper surface causes the high-temperature smoke to be reflected and deflected multiple times during the flow process, extending the flow path of the smoke. The advantage of this design is that the time the smoke stays in the bottom area of ​​the pot is significantly increased, thereby extending the heat exchange time between the high-temperature smoke and the bottom of the pot. This process effectively increases the heating area and uniformity of the pot, allowing the heat generated by combustion to be more fully utilized, thereby improving the thermal efficiency of the gas stove.

[0015] 3. The corrugated structure not only optimizes the transfer of heat energy on the upper surface, but also forms a multi-layer heat-insulating structure through the design of its lower surface. Specifically, multiple air layers are formed between the lower surface of the corrugation and the air, which play a role in heat insulation and slow down the speed of heat conduction from the inside to the outside. This design allows the internal heat to accumulate in the bottom area of ​​the pot for a longer time, reducing the speed of heat dissipation to the outside, thereby further improving the utilization efficiency of heat energy.

[0016] 4. Through the guiding effect of the upper surface and the heat insulation effect of the lower surface, the corrugated structure can significantly improve the overall thermal efficiency of the gas stove. Traditional gas stoves often have the problem of severe heat loss and low thermal efficiency. The present invention solves this problem through the ingenious design of the corrugated structure, so that the gas stove can produce a higher thermal effect under the same gas consumption. This not only shortens the cooking time and improves the use efficiency, but also greatly reduces energy consumption, which meets the requirements of modern energy conservation and environmental protection.

[0020] The invention is further described in detail below with reference to the accompanying drawings. A high-efficiency energy-gathering plate for a gas furnace comprises a conical plate 1 which is larger at the top and smaller at the bottom, the bottom of the conical plate 1 is provided with a lower flange 2 extending toward the center of the circle, the top of the conical plate 1 is provided with an upper panel 3 extending outward, the surface of the upper panel 3 is provided with a plurality of upper convex rings 31 bulging upward, a downward concave lower convex ring 32 is formed between the inner and outer upper convex rings 31, and the plurality of upper convex rings 31 and the lower convex rings 32 form a wavy plate surface of the upper panel 3.

[0021] In one embodiment, a plurality of lower legs 4 are extended downward from the bottom of the upper panel 3, and a plurality of upper furnace ears 5 are extended upward from the top of the upper panel 3.

[0022] In one embodiment, the upper panel 3 is in the shape of a conical disk 1 with a high outer side and a low inner side.

[0023] In one embodiment, the upper end surface of the upper furnace ear 5 is provided with a plurality of stepped surfaces 51 which are higher outside and lower inside.

[0024] In one embodiment: the step surface 51, the lowest level is a slope that is higher outside and lower inside.

[0025] In one embodiment, the conical disk 1 and the upper panel 3 are integrally cast.

[0026] Working principle: The conical dish 1 of the present invention is designed to be larger at the top and smaller at the bottom, and its bottom extends toward the center of the circle to form a lower flange 2. When the gas burns, the flame directly contacts the lower part of the conical dish. Due to the conical design of the conical dish, the heat of the flame can naturally gather toward the center area and be guided upward along the dish body. This design effectively reduces the lateral diffusion of heat, so that more heat energy is concentrated in the central area of ​​the bottom of the pot, thereby improving the thermal efficiency.

[0027] The upper panel 3 extends to the top of the conical disk and is provided with a plurality of upper convex rings 31 and lower convex rings 32 that bulge upwards. These convex rings form a corrugated structure of the upper panel. When the high-temperature flue gas flows upward along the conical disk and contacts the corrugated structure of the upper panel, the surface of the upper convex ring can guide the high-temperature flue gas to diffuse along the corrugated path.

[0028] The corrugated structure makes the flow path of the high-temperature smoke tortuous and extended, increasing the contact area and time between the smoke and the bottom of the pot, thereby prolonging the heat transfer process. In this way, the heat can be more fully transferred to the bottom of the pot, effectively improving the uniformity of the heat and the overall heating efficiency of the pot.

[0029] The corrugated structure not only optimizes the heat transfer, but also forms multiple insulation layers between its lower surface and the air. These insulation layers are filled with air, which can play a good role in heat preservation and slow down the speed of heat conduction from the inside of the corrugated structure to the outside. This multi-layer insulation structure ensures that the heat inside the energy-gathering disk can be concentrated in the bottom area of ​​the pot for a long time, reducing the speed of heat dissipation to the outside, thereby further improving the utilization efficiency of thermal energy.

[0030] Based on the above working principle, the present invention exhibits the following significant technical advantages: 1. Heat concentration and efficient transfer: The conical disc design allows the heat generated by combustion to be concentrated and directed upward, reducing ineffective heat loss. This concentration effect ensures that more heat can be effectively transferred to the bottom of the pot, improving the efficiency of gas utilization.

[0031] 2. Extend heat exchange time and improve thermal efficiency: The corrugated structure of the upper panel prolongs the flow path of high-temperature smoke, which increases the contact time between the smoke and the bottom surface of the pot. Delayed heat exchange not only improves the effect of heat transfer, but also significantly improves the overall thermal efficiency of the gas stove, making the cooking process more efficient.

[0032] 3. Reduce heat loss and enhance energy-saving effect: The multi-layer heat insulation structure formed on the lower surface of the corrugated structure effectively slows down the speed of heat diffusion outward, ensuring that the heat energy is concentrated in the bottom area of ​​the pot for a long time. This design greatly reduces energy waste, improves the energy-saving effect of gas stoves, and meets modern environmental protection requirements.

[0033] 4. The bottom of the pot is heated evenly, and the cooking effect is better: The corrugated structure not only increases the heat transfer time, but also ensures that the bottom of the pot is heated more evenly through its unique shape design, avoiding the problems of local overheating or uneven heating in traditional gas stoves, thereby improving the overall cooking effect.

[0034] 5. Simple structure and strong applicability: Although the present invention adopts an innovative corrugated structure and conical disc design, its overall structure is still simple and easy to manufacture, and is suitable for various types of gas stoves. It can not only improve the thermal efficiency of existing equipment, but also has low manufacturing and maintenance costs, and has a wide range of market application prospects.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
