Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen utensils, and in particular to an energy-concentrating ring, a pot support, and a stove. Background Technology
[0002] Currently, most methods for improving combustion efficiency on the market are achieved by optimizing burner design or adding double or even triple-layer energy-concentrating discs. This is achieved by adjusting the burner nozzle diameter or flame angle, or by using an air layer for insulation, thereby improving flue gas combustion efficiency.
[0003] However, these designs have the following drawbacks:
[0004] 1. Burner optimization design revealed issues such as backfire and flame lift-off.
[0005] 2. Double- or even triple-layered energy-concentrating discs are mostly bulky and round.
[0006] Existing gas stoves suffer from high heat exchange losses, low heat exchange efficiency, and low energy utilization of flue gas. Utility Model Content
[0007] The technical problem to be solved by this utility model is to overcome the defects of high heat exchange loss, low heat exchange efficiency and low energy utilization of flue gas in the existing gas stove, and to provide an energy-concentrating ring, pot support and stove.
[0008] The present invention solves the above-mentioned technical problems through the following technical solution:
[0009] An energy-concentrating ring is disclosed, wherein the energy-concentrating ring has a hollow structure, the energy-concentrating ring includes a vertical outer peripheral wall and an inner peripheral wall that slopes downward toward the center of the energy-concentrating ring, the upper edge of the inner peripheral wall is connected to the upper edge of the outer peripheral wall, the lower edge of the outer peripheral wall has a guide surface that slopes downward toward the center of the energy-concentrating ring, and the lower side of the energy-concentrating ring is open.
[0010] In this design, the inner wall of the energy-concentrating ring is inclined. During operation, high-temperature flue gas rises along the inner wall of the ring towards the outer periphery and then descends along the vertical outer wall. As the flue gas descends, its potential energy is converted into kinetic energy. The increased velocity of the flue gas leads to a decrease in pressure. Under this pressure difference, the gas rapidly enters the lower channel of the energy-concentrating ring. The high-temperature flue gas then enters the hollow interior of the ring through an open opening at the bottom, mixing with the supplementary air inside. Inside the hollow ring, the high-temperature flue gas rises while the ambient air sinks, creating a localized vortex. This preheats the supplementary air through heat conduction and radiation. The heated air, along with the flue gas, enters the burner at the center of the energy-concentrating ring, reducing substances produced by incomplete combustion. Simultaneously, some of the secondary air is drawn into the burner along the intake channel for secondary combustion, improving burner efficiency and further enhancing the stove's combustion efficiency. In addition, the guide surface on the lower side of the outer peripheral wall, together with the cooktop, forms a surrounding air intake channel that expands outward and contracts inward, accelerating the entry of secondary air and high-temperature flue gas, thereby improving the combustion efficiency of the burner and further enhancing the combustion efficiency of the cooktop.
[0011] Preferably, the inclination angle of the inner peripheral wall relative to the vertical direction is 65°-75°.
[0012] Preferably, the inclination angle of the inner peripheral wall relative to the vertical direction is 60°.
[0013] Preferably, the angle of the guide surface relative to the vertical direction is 65°-75°.
[0014] Preferably, the angle of the guide surface relative to the vertical direction is 60°.
[0015] Preferably, the outer peripheral wall and the inner peripheral wall are connected by an arc-shaped surface.
[0016] In this design, the outer peripheral wall and the inner peripheral wall are connected by an arc-shaped surface, which helps the high-temperature flue gas diffuse more smoothly toward the outer periphery.
[0017] Preferably, the inner peripheral wall has a downwardly recessed groove on its inner peripheral side.
[0018] In this design, a downwardly recessed groove is provided on the inner circumferential side of the inner circumferential wall to hold liquid falling from above, preventing the liquid from splashing directly onto the burner.
[0019] A pot support that includes a concentrating coil as described above.
[0020] A cooker includes a burner and a pot support as described above, the burner being located at the center of the pot support.
[0021] Preferably, the stove further includes a liquid collection tray, which is located below the pot support and has an inclined surface below the guide surface, the inclined surface being inclined toward the center and upward of the energy-concentrating ring.
[0022] In this design, the inclined surface below the energy-concentrating ring, together with the guide surface of the energy-concentrating ring, forms an outward-expanding and inward-contracting surrounding air intake channel, which accelerates the entry of secondary air and high-temperature flue gas, thereby improving the combustion efficiency of the burner and further enhancing the combustion efficiency of the stove.
[0023] The significant advantages of this invention are as follows: The inner wall of the energy-concentrating ring is inclined. During use, high-temperature flue gas rises along the inner wall to the outer periphery and then descends along the vertical outer wall. As the flue gas descends, its potential energy is converted into kinetic energy. The increased velocity of the flue gas leads to a decrease in pressure. Under this pressure difference, the gas rapidly enters the lower channel of the energy-concentrating ring. The high-temperature flue gas enters the hollow interior of the ring through an open opening at the bottom, mixing with the supplementary air inside. Inside the hollow ring, the high-temperature flue gas rises while the ambient air sinks, creating a localized vortex. This preheats the supplementary air through heat conduction and radiation. The heated air, along with the flue gas, enters the burner at the center of the energy-concentrating ring, reducing substances produced by incomplete combustion. Simultaneously, some of the secondary air is drawn into the burner along the intake channel for secondary combustion, improving burner efficiency and further enhancing the stove's combustion efficiency. Furthermore, the guide surface on the lower side of the outer peripheral wall, together with the cooktop, forms an outward-expanding, inward-contracting surrounding air intake channel, accelerating the entry of secondary air and high-temperature flue gas, thereby improving the combustion efficiency of the burner and further enhancing the combustion efficiency of the cooktop. This pot support and cooktop have the same effect. The energy-concentrating ring, through its vertical outer peripheral wall, the guide surface along the lower edge of the outer peripheral wall, and the open structure on the lower side, significantly increases the residence time of secondary air within the energy-concentrating ring and improves its energy-concentrating effect, thus increasing the thermal efficiency of the cooktop. Pot supports and cooktops with this energy-concentrating ring have the same effect. Attached Figure Description

Detailed Implementation
[0031] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.
[0032] like Figure 1-2 As shown, this embodiment provides a stove 100, which includes a burner 110 and a pot support 120, with the burner 110 located at the center of the pot support 120.
[0033] like Figure 4 As shown, the pot support 120 includes an energy-concentrating ring 121 and corner pieces 122. The corner pieces 122 are disposed on the energy-concentrating ring 121 and are evenly distributed circumferentially around the energy-concentrating ring 121. In this embodiment, the corner pieces 122 are inserted into the energy-concentrating ring 121 and penetrate the energy-concentrating ring 121 in the vertical direction V. However, this utility model is not limited to this, and the corner pieces 122 can be connected to the energy-concentrating ring 121 using other existing structural arrangements.
[0034] In this embodiment, the corner piece 122 and the energy-concentrating ring 121 are combined into a whole to form the pot support 120. However, the present invention is not limited to this. The pot support 120 can also be set separately from the energy-concentrating ring 121, that is, a separate pot support 120 without the energy-concentrating ring 121 can be set, and then the energy-concentrating ring 121 can be mounted on the pot support 120. The energy-concentrating ring 121 is formed as a separate component relative to the pot support 120 or as a complete component that can be detached from the pot support 120.
[0035] like Figure 5-6 As shown, the energy-concentrating ring 121 has a hollow structure. The energy-concentrating ring 121 includes a vertical outer peripheral wall 1211 and an inner peripheral wall 1214 that slopes downward toward the center of the energy-concentrating ring 121. The upper edge of the inner peripheral wall 1214 is connected to the upper edge of the outer peripheral wall 1211. The lower edge of the outer peripheral wall 1211 has a guide surface 1212 that slopes downward toward the center of the energy-concentrating ring 121. The lower side of the energy-concentrating ring 121 is open.
[0036] like Figure 3 As shown, the inner peripheral wall 1214 of the energy-concentrating ring 121 is inclined. During use, high-temperature flue gas (indicated by the red arrow) rises along the inner peripheral wall 1214 of the energy-concentrating ring 121 towards the outer periphery and then descends along the vertical outer peripheral wall 1211. During its downward movement, the high-temperature flue gas converts potential energy into kinetic energy. As the flue gas velocity increases, its pressure decreases. Under the influence of this pressure difference, the gas rapidly enters the air intake channel 140 on the lower side of the energy-concentrating ring 121. The high-temperature flue gas enters the hollow interior of the energy-concentrating ring 121 through the open opening on the lower side, mixing with the supplementary air inside the hollow interior. Inside the hollow interior of the energy-concentrating ring 121, the high-temperature flue gas rises while the ambient air (indicated by the blue arrow) sinks, forming a local vortex. The supplementary air (indicated by the blue arrow) is preheated through heat conduction and heat radiation. Heated air (indicated by the orange dashed arrow) enters the burner 110 at the center of the energy-concentrating ring 121 along with high-temperature flue gas. This reduces substances produced by incomplete combustion in the flue gas. Simultaneously, some secondary air is drawn into the burner 110 along the air intake channel 140 for secondary combustion, improving the efficiency of the burner 110 and further enhancing the combustion efficiency of the cooktop 100. Furthermore, the guide surface 1212 on the lower side of the outer peripheral wall 1211, together with the cooktop 100's surface, forms an expanding-inward-contracting surrounding air intake channel 140, accelerating the entry of secondary air and high-temperature flue gas, thereby improving the combustion efficiency of the burner 110 and further enhancing the combustion efficiency of the cooktop 100. The energy-concentrating ring 121, through its vertical outer peripheral wall 1211, the guide surface 1212 along its lower edge, and the open structure on its lower side, significantly increases the residence time of secondary air within the energy-concentrating ring 121 and improves its energy-concentrating effect, thus increasing the thermal efficiency of the cooktop 100.
[0037] Preferably, the inclination angle of the inner peripheral wall 1214 relative to the vertical direction V is 65°-75°. More preferably, the inclination angle of the inner peripheral wall 1214 relative to the vertical direction V is 60°. Within this inclination angle, the high-temperature flue gas can rise more easily.
[0038] Preferably, the angle of the guide surface 1212 relative to the vertical direction V is 65°-75°. More preferably, the angle of the guide surface 1212 relative to the vertical direction V is 60°. Within this tilt angle, the guide surface 1212 can better guide the high-temperature flue gas into the channel.
[0039] The outer peripheral wall 1211 and the inner peripheral wall 1214 are connected by an arc-shaped surface 1213. The connection between the outer peripheral wall 1211 and the inner peripheral wall 1214 by the arc-shaped surface 1213 can help the high-temperature flue gas diffuse more smoothly toward the outer periphery.
[0040] The inner circumferential wall 1214 has a downwardly recessed groove 1215 on its inner circumferential side. This groove 1215 on the inner circumferential side of the inner circumferential wall 1214 can collect liquid falling from above, preventing direct splashing onto the burner 110. When liquid falls from above onto the surface of the energy-concentrating ring 121, it flows downward along the inclined inner circumferential wall 1214, flowing towards the burner 110 at the center of the energy-concentrating ring 121, potentially splashing onto the burner 110 and causing adverse consequences. The groove 1215 on the inner circumferential side of the inner circumferential wall 1214 can collect the liquid, reducing the kinetic energy of the liquid flowing down from the inner circumferential wall 1214 of the energy-concentrating ring 121, thereby preventing direct splashing onto the burner 110.
[0041] On the inner periphery of the groove 1215, the inner periphery edge of the inner peripheral wall 1214 is also provided with a downward flange 1216. The flange 1216 can guide the liquid overflowing from the groove 1215 to the liquid tray 130, thereby preventing it from flowing toward the burner 110 or toward the hollow part inside the energy-concentrating ring 121, making it easier to clean the stove 100.
[0042] The cooktop 100 also includes a liquid tray 130, which is located below the pot support 120. The liquid tray 130 has an inclined surface 131 below the guide surface 1212, and the inclined surface 131 is inclined towards the center and upward of the energy-concentrating ring 121.
[0043] The inclined surface 131 below the energy-concentrating ring 121, together with the guide surface 1212 of the energy-concentrating ring 121, forms an outwardly expanding and inwardly contracting surrounding air intake channel 140, which accelerates the entry of secondary air and high-temperature flue gas, thereby improving the combustion efficiency of the burner 110 and further improving the combustion efficiency of the stove 100.
[0044] Reference Figure 3 As can be clearly seen from the cross-sectional view, the guide surface 1212 of the energy-concentrating ring 121 and the inclined surface 131 of the liquid-collecting plate 130 form a trumpet-shaped structure. The air intake channel 140 with this structure can accelerate the entry of secondary air and high-temperature flue gas.
