Description

Technical Field

[0001] This utility model relates to the field of energy-concentrating coils, and in particular to an energy-concentrating coil device and a gas stove including the same. Background Technology

[0002] As an indispensable cooking tool in daily life, improving the thermal efficiency of household gas stoves is of great significance for energy conservation and emission reduction. By adding an energy-concentrating ring between the gas stove burner and the bottom of the pot to form a semi-enclosed space, heat loss can be effectively reduced, thus improving thermal efficiency. At the same time, the energy-concentrating ring can also optimize the flame structure, making the flame more stable and uniform, thereby improving the performance.

[0003] However, most existing condensing coils reduce heat loss by forming a semi-enclosed structure around the burner. While this improves thermal efficiency to some extent, it also introduces new problems. Firstly, this semi-enclosed structure affects the supply of secondary air. Combustion requires sufficient oxygen, and a semi-enclosed structure may restrict airflow, leading to incomplete combustion and increased pollutants. Secondly, existing condensing coils lack utilization of the heat carried by the heated air outside the coil. If this heat is not effectively utilized, it will dissipate into the surrounding environment, resulting in energy waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of insufficient secondary air supply and insufficient utilization of external heating air in the prior art, and to provide an energy-concentrating coil device and a gas stove including the same.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides an energy-concentrating ring device, which includes an energy-concentrating ring body. The energy-concentrating ring body includes an energy-concentrating cover and a rolled edge. An opening is provided at the center of the energy-concentrating cover for placing a burner. The rolled edge is provided on the outer edge of the energy-concentrating cover. The rolled edge includes a blocking part and a return part. One end of the blocking part is connected to the outer edge of the energy-concentrating cover, and the other end of the blocking part extends downward and is connected to the return part. The return part extends toward the opening.

[0007] In this design, the heated air generated by the burner diffuses outward along the upper and lower surfaces of the energy-concentrating shroud. The heated air on the upper surface of the shroud is trapped inside, while the heated air on the lower surface diffuses to the outer edge of the shroud. Due to the presence of a downward-facing obstruction, the heated air cannot continue to diffuse outward and changes its flow direction upon impacting the obstruction, flowing downward. This downward-flowing heated air then flows along a return flow section facing the opening, thus returning the heated air to the burner as secondary air replenishment. Furthermore, the heated air is retained at the bottom of the shroud due to the rolled edges, forming an insulation layer, which helps save energy.

[0008] Preferably, the reflux section is V-shaped, with the outer end of the top of the reflux section connected to the blocking section, and the inner end of the top of the reflux section extending toward the lower surface of the energy-concentrating shield.

[0009] In this design, the V-shaped recirculation section allows the heated air to flow along the lower surface of the energy-concentrating cover towards the opening, reducing the possibility of heated air escaping from the end of the recirculation section and further improving the efficiency of secondary air replenishment.

[0010] Preferably, the blocking part includes a smooth part and a vertical part. The smooth part has a smooth curved surface, and its two ends are respectively connected to the outer edge of the energy-concentrating shield and the top of the vertical part. The vertical part extends downward in a vertical direction and is connected to the return part.

[0011] In this design, the smooth section of the curved surface transitions between the energy-concentrating shield and the vertical section, reducing damage from impacts. Simultaneously, the vertically downward-pointing section maximizes the prevention of heated air escaping to the outside.

[0012] Preferably, the outer edge of the energy-concentrating shield is higher than the edge of the opening, and the outer edge and the edge of the opening form a slope.

[0013] In this solution, the inclined flow guiding structure adopted by the energy-concentrating cover can guide the overflow liquid to be efficiently guided away along the inclined surface, forming a self-cleaning effect and effectively reducing the oil stain adhesion rate and the frequency of cleaning and maintenance.

[0014] Preferably, the energy-concentrating shield further includes a plurality of supporting feet, each of the supporting feet including a connecting portion and a protrusion. The plurality of connecting portions are circumferentially spaced around the center of the opening and connected to the upper surface of the energy-concentrating shield. One end of the protrusion is connected to the connecting portion, and the other end of the protrusion extends toward the center of the opening, and a cavity is formed between the protrusion and the upper surface of the energy-concentrating shield.

[0015] In this design, the protrusion extends beyond the connecting portion to form a cavity between the protrusion and the energy-concentrating cover. This cavity provides more space to replenish the secondary air in the area, reducing the possibility of incomplete combustion due to insufficient secondary air.

[0016] Preferably, the energy-concentrating cover also includes a plurality of anti-tipping feet, with at least one anti-tipping foot provided between each pair of adjacent support feet.

[0017] In this solution, anti-tipping feet are installed between two adjacent support feet to avoid excessive gaps between adjacent feet, thereby reducing the possibility of the pot tipping over from the gaps between the support feet when it is not placed in the correct position.

[0018] Preferably, the bottom of the anti-tipping foot piece is connected to the upper surface of the energy-concentrating cover, and the height of the anti-tipping foot piece protruding from the upper surface of the energy-concentrating cover is less than the height of the supporting foot piece protruding from the upper surface of the energy-concentrating cover.

[0019] In this design, the height of the anti-tipping foot piece is less than the height of the supporting foot piece, which reduces the impact of the anti-tipping foot piece on the normal use of the cookware.

[0020] Preferably, the top of the anti-tipping pot foot piece has a straight section and an inclined section, the inclined section extending inward and downward in an inclined direction from one end of the straight section near the opening.

[0021] In this design, the straight section provides support when the cookware tipps over, while the end closest to the opening, i.e. the end closest to the cookware, has an inclined section to further reduce the impact on normal use of the cookware.

[0022] Preferably, each of the supporting feet further includes a supporting portion, the energy-concentrating cover has a through hole, the supporting foot is disposed through the through hole, the supporting portion is connected to the connecting portion, and the supporting portion extends downward from the through hole.

[0023] In this design, the presence of the support structure can improve the stability of the entire energy-concentrating coil device.

[0024] This utility model also provides a gas stove, which includes the energy-concentrating coil device as described above.

[0025] In this design, the heated air generated by the burner diffuses outward along the upper and lower surfaces of the energy-concentrating shroud. The heated air on the upper surface of the shroud is trapped inside, while the heated air on the lower surface diffuses to the outer edge of the shroud. Due to the presence of a downward-facing obstruction, the heated air cannot continue to diffuse outward and changes its flow direction upon impacting the obstruction, flowing downward. This downward-flowing heated air then flows along a return flow section facing the opening, thus returning the heated air to the burner as secondary air replenishment. Furthermore, the heated air is retained at the bottom of the shroud due to the rolled edges, forming an insulation layer, which helps save energy.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] The present invention relates to an energy-concentrating coil device and a gas stove including the same. Heated air generated by combustion in the burner diffuses outward along the upper and lower surfaces of the energy-concentrating shroud. Heated air on the upper surface of the shroud is trapped inside, while heated air on the lower surface diffuses to the outer edge of the shroud. Due to the presence of a downward-facing blocking section, the heated air cannot continue to diffuse outward and, upon impact with the blocking section, changes its flow direction and flows downward. This downward-flowing heated air then flows along a return flow section facing the opening, thus returning the heated air to the burner as secondary air replenishment. Furthermore, the heated air is retained at the lower part of the shroud due to the rolled edge, forming an insulation layer, which helps save energy. Attached Figure Description

[0053] Burner 200 Detailed Implementation

[0054] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0055] like Figures 1-4 As shown, this embodiment provides a concentrating coil device 100, which includes a concentrating coil body 1. The concentrating coil body 1 includes a concentrating cover 11 and a rolled edge 12. The concentrating cover 11 has a square or circular structure. In this embodiment, it has a square structure. The concentrating cover 11 has chamfered corners around its perimeter. An opening 111 is provided in the center of the concentrating cover 11. The opening 111 is circular and is used to place the burner 200. The rolled edge 12 is provided on the outer edge of the concentrating cover 11. The rolled edge 12 includes a blocking part 121 and a return part 122. One end of the blocking part 121 is connected to the outer edge of the concentrating cover 11, and the other end of the blocking part 121 extends downward and is connected to the return part 122. The return part 122 extends toward the opening 111.

[0056] Thus, the heated air generated by the combustion of the burner 200 diffuses outward along the upper and lower surfaces of the energy-concentrating cover 11. The heated air on the upper surface of the energy-concentrating cover 11 is blocked inside, while the heated air on the lower surface diffuses to the outer edge of the energy-concentrating cover 11. Due to the presence of the downward-facing blocking part 121, the heated air cannot continue to diffuse outward and changes its flow direction by impacting the blocking part 121, flowing downward. The downward-flowing heated air flows along the return flow part 122 facing the opening 111, thereby delivering the heated air back to the burner 200 as secondary air replenishment. Furthermore, the heated air is retained at the lower part of the energy-concentrating cover 11 due to the rolled edge 12, forming an insulation layer, which helps to save energy.

[0057] In this embodiment, as Figure 3 As shown, the return flow section 122 is V-shaped. The outer end of the top of the return flow section 122 is connected to the blocking section 121, and the inner end of the top of the return flow section 122 extends toward the lower surface of the energy-concentrating cover 11. Preferably, the outer end of the top of the return flow section 122 is higher than the inner end of the top of the return flow section 122, that is, the side of the V-shape connecting to the blocking section 121 is longer than the side extending toward the lower surface of the energy-concentrating cover 11. With this structure, the heated air can flow along the lower surface of the energy-concentrating cover 11 to the opening 111 through the V-shaped return flow section 122, reducing the possibility of heated air escaping from the end of the return flow section 122 and further improving the efficiency of secondary air replenishment.

[0058] In this embodiment, as Figure 3 As shown, the blocking part 121 includes a smooth part 1211 and a vertical part 1212. The smooth part 1211 has a smooth curved surface, and its two ends are respectively connected to the outer edge of the energy-concentrating cover 11 and the top of the vertical part 1212. The vertical part 1212 extends downward in a vertical direction and is connected to the return part 122. The smooth curved surface of the smooth part 1211, which bridges the energy-concentrating cover 11 and the vertical part 1212, can reduce damage caused by collisions. At the same time, the vertically downward vertical part 1212 can block the escape of heated air to the outside to the greatest extent. In other embodiments, the vertical part 1212 may also be inclined outward and downward.

[0059] Specifically, such as Figure 1 and Figure 2 As shown, the outer edge of the energy-concentrating shield 11 is higher than the edge of the opening 111, and the outer edge and the edge of the opening 111 form a slope.

[0060] Thus, the inclined flow guiding structure adopted by the energy-concentrating cover 11 can guide the overflow liquid to be efficiently guided away along the inclined surface, forming a self-cleaning effect and effectively reducing the oil stain adhesion rate and the frequency of cleaning and maintenance.

[0061] Specifically, such as Figure 1As shown, the energy-concentrating shield 11 also includes four support feet 13. Each support foot 13 includes a connecting portion 131 and a protrusion 132. The four connecting portions 131 are circumferentially spaced around the center of the opening 111 and connected to the upper surface of the energy-concentrating shield 11. In each support foot 13, one end of the protrusion 132 is connected to the connecting portion 131, and the other end of the protrusion 132 extends toward the center of the opening 111, forming a cavity 134 between the protrusion 132 and the upper surface of the energy-concentrating shield 11.

[0062] Thus, the protrusion 132 extends out of the connecting portion 131 to form a cavity 134 between the protrusion 132 and the energy-concentrating cover 11. This cavity 134 can provide more space to replenish the secondary air there, reducing the possibility of incomplete combustion due to insufficient secondary air.

[0063] In this embodiment, four support feet 13 are disposed at the four corners of the energy-concentrating ring, and four connecting parts 131 are disposed on the diagonal lines of the energy-concentrating ring. The number of four support feet 13 is merely illustrative; those skilled in the art can adjust them according to the size of the energy-concentrating ring and other requirements, and this embodiment is not limited thereto.

[0064] Specifically, the energy-concentrating cover 11 also includes a plurality of anti-tipping foot pieces 14, with at least one anti-tipping foot piece 14 provided between each pair of adjacent support foot pieces 13.

[0065] Thus, by setting anti-tipping foot pieces 14 between two adjacent support foot pieces 13, the gap between adjacent foot pieces can be avoided to be too large, thereby reducing the possibility of the pot tipping over from the gap between the support foot pieces 13 when it is not placed in the correct position.

[0066] In this embodiment, as Figure 1 As shown, there are four anti-tipping foot pieces 14. The four anti-tipping foot pieces 14 are respectively positioned at the center of the four sides of the energy-concentrating ring, that is, one anti-tipping foot piece 14 is placed between every two adjacent support foot pieces 13. The number of four anti-tipping foot pieces 14 is only for illustrative purposes; those skilled in the art can adjust them according to the size of the energy-concentrating ring and other requirements, and this embodiment is not limited thereto.

[0067] Specifically, the bottom of the anti-tipping foot piece 14 is connected to the upper surface of the energy-concentrating cover 11, and the height of the anti-tipping foot piece 14 protruding from the upper surface of the energy-concentrating cover 11 is less than the height of the supporting foot piece 13 protruding from the upper surface of the energy-concentrating cover 11.

[0068] Thus, the height of the anti-tipping foot piece 14 is less than the height of the supporting foot piece 13, which can reduce the impact of the anti-tipping foot piece 14 on the normal use of the cookware.

[0069] In this embodiment, the top of the anti-tipping pot leg 14 has a straight section 141 and an inclined section 142. The inclined section 142 extends inward and downward in an inclined direction from the end of the straight section 141 near the opening 111. The straight section 141 can provide support when the pot tipes over. The end near the opening 111, which is the end near the pot, has the inclined section 142 to further reduce the impact on the normal use of the pot.

[0070] Specifically, such as Figure 1 and Figure 2 As shown, each support foot 13 also includes a support portion 133. The energy-concentrating cover 11 has a through hole 15, and the support foot 13 is disposed through the through hole 15. The support portion 133 is connected to the connecting portion 131, and the support portion 133 extends downward from the through hole 15.

[0071] Thus, the presence of the support part 133 can improve the stability of the entire energy-concentrating ring device 100.

[0072] The support portion 133, the connecting portion 131, and the protrusion 132 are integrally formed. The support foot 13 can be fixedly connected to the through hole 15 or detachably connected to the through hole 15.

[0073] In this embodiment, the support foot 13 is fixedly connected to the through hole 15. The top of the support part 133 is connected to the connecting part 131, and the bottom of the support part 133 is connected to the stove surface of the gas stove 1000.

[0074] like Figure 5 As shown, this embodiment also provides a gas stove 1000, which includes the energy-concentrating coil device 100 as described above.

[0075] Thus, the heated air generated by the combustion of the burner 200 diffuses outward along the upper and lower surfaces of the energy-concentrating cover 11. The heated air on the upper surface of the energy-concentrating cover 11 is blocked inside, while the heated air on the lower surface diffuses to the outer edge of the energy-concentrating cover 11. Due to the presence of the downward-facing blocking part 121, the heated air cannot continue to diffuse outward and changes its flow direction by impacting the blocking part 121, flowing downward. The downward-flowing heated air flows along the return flow part 122 facing the opening 111, thereby delivering the heated air back to the burner 200 as secondary air replenishment. Furthermore, the heated air is retained at the lower part of the energy-concentrating cover 11 due to the rolled edge 12, forming an insulation layer, which helps to save energy.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
