Description

Technical Field

[0001] This utility model relates to the field of stove technology, specifically to an energy-concentrating plate, a pot support, and a gas stove. Background Technology

[0002] In actual use, when a gas stove is in operation, the cookware is placed on the pot support, and the high-temperature flue gas generated by the combustion of gas flows out through the space between the cookware and the energy-concentrating plate of the pot support. Although the traditional arc-shaped energy-concentrating plate can radiate some of the heat from the flue gas to the bottom of the pot to heat the cookware, a considerable amount of heat still escapes into the surrounding environment, resulting in energy waste.

[0003] Therefore, existing methods involve setting multiple baffle structures on an arc-shaped energy-concentrating plate to extend the residence time of high-temperature flue gas, allowing the energy-concentrating plate to radiate more heat to the cookware, thereby improving thermal efficiency. However, when broth or dust and other dirt fall into the bottom of the baffle structure, cleaning is difficult, and long-term accumulation of dirt can easily corrode the energy-concentrating plate, affecting its service life and performance. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, an energy-concentrating disk is provided, the technical solution of which is as follows.

[0005] The energy-concentrating disc includes an annular disc body, which has an outer ring top and an inner ring bottom, a flue gas guiding section and a flue gas suppressing section. Both the flue gas guiding section and the flue gas suppressing section are located between the outer ring top and the inner ring bottom, and the flue gas suppressing section is connected to the end of the flue gas guiding section. The flue gas guiding section is constructed in an arc shape. In the axial direction of the annular disc body, the outer ring top is higher than the inner ring bottom, and the center of the flue gas guiding section is higher than the outer ring top.

[0006] This utility model's energy-concentrating plate includes a smoke suppression section and an arc-shaped smoke guide section. In the axial direction of the annular plate, the center of the smoke guide section is higher than the top of the outer ring. When the energy-concentrating plate is used in cooking, the smoke suppression section suppresses the outflow of high-temperature smoke, extending the residence time of the high-temperature smoke, allowing the energy-concentrating plate to radiate more heat towards the cookware. Simultaneously, the arc-shaped smoke guide section prevents scum or dust from accumulating, making cleaning easier. Furthermore, the fact that the center of the smoke guide section is higher than the top of the outer ring helps reflect the high-temperature smoke upwards, thus focusing the radiated heat on the bottom of the pot. It also guides the high-temperature smoke to flow closer to the bottom surface of the pot, resulting in more even heating of the bottom, reduced heat loss, and ultimately improved thermal efficiency.

[0007] For example, from the bottom of the inner ring to the top of the outer ring, the annular disc has at least two sets of flue gas sections. Each set of flue gas sections includes a flue gas guiding section and a flue gas suppressing section. The connection point between the flue gas guiding section and the flue gas suppressing section in each set is the lowest point of the flue gas guiding section. This arrangement can more effectively guide the high-temperature flue gas along the flue gas guiding section, making the flow smoother and preventing turbulence within the section. It also guides the high-temperature flue gas closer to the bottom surface of the pot, resulting in more uniform heating of the pot bottom, reduced heat loss, and thus improved thermal efficiency.

[0008] For example, in at least two groups of flue gas sections, the group closest to the bottom of the inner ring is defined as the inner flue gas section group. In the direction parallel to the installation plane, the width of the inner flue gas section group is greater than the width of the other flue gas section groups. This arrangement can more effectively guide the high-temperature flue gas along the flue gas guide section, making the flow of high-temperature flue gas smoother. It also extends the residence time of the high-temperature flue gas, allowing the energy-concentrating plate to radiate more heat towards the cookware, reducing heat loss, and thus improving thermal efficiency.

[0009] For example, the flue gas suppression section includes a first suppression section extending from the bottom of the inner ring. In a direction parallel to the mounting plane, the first suppression section has a first width L1, which is 5mm to 15mm. The mounting plane direction is perpendicular to the axial direction of the annular disc. With this configuration, when the energy-concentrating disc is used in a cooking scenario, on the one hand, the first suppression section extending from the bottom of the inner ring suppresses secondary air, allowing the secondary air to be preheated by the energy-concentrating disc. The preheated air promotes more complete and intense combustion of the gas. On the other hand, the first width L1 of the first suppression section, within this range, provides better suppression of high-temperature flue gas flow, prolongs the residence time of high-temperature flue gas, allows the energy-concentrating disc to radiate more heat towards the cookware, and further enhances the suppression of secondary air, thereby improving thermal efficiency.

[0010] For example, the first suppression section has a first end and a second end, and the first suppression section forms a straight line, an arc, or a step between the first end and the second end. This configuration not only further enhances the effect of suppressing secondary air and flue gas, but also increases the time for the secondary air to be preheated by the energy-concentrating plate. The preheated air can promote more complete and intense combustion of the gas, prolong the residence time of high-temperature flue gas, and allow the energy-concentrating plate to radiate more heat towards the cookware. It also avoids the phenomenon of the flame passively heating the first suppression section due to the first suppression section being close to the burner flame, thus preventing a decrease in thermal efficiency.

[0011] For example, the first end is closer to the top of the outer ring than the second end, and in the axial direction of the annular disc, the first end is not lower than the second end. This setting improves the effect of suppressing secondary air and flue gas, increases the time for the secondary air to be preheated by the energy-concentrating disc, and the preheated air can promote more complete and intense combustion of the gas, prolong the residence time of high-temperature flue gas, and allow the energy-concentrating disc to radiate more heat towards the cookware.

[0012] For example, in the axial direction of the annular disc, there is a height distance H between the first end and the second end, which is 3mm to 10mm. This configuration, with the height distance H within this range, not only further enhances the suppression of secondary air and flue gas, but also increases the preheating time of the secondary air by the energy-concentrating disc. The preheated air promotes more complete and intense combustion of the gas, prolongs the residence time of the high-temperature flue gas, and allows the energy-concentrating disc to radiate more heat towards the cookware. Furthermore, it avoids the flame of the first suppression section being too close to the burner flame, which would passively heat the first suppression section and reduce thermal efficiency.

[0013] For example, the flue gas suppression section includes a second suppression section, which is closer to the top of the outer ring than the first suppression section. In a direction parallel to the mounting plane, the second suppression section has a second width L2, which is 5mm to 15mm. With this configuration, when the energy-concentrating plate is used in a cooking scenario, the second suppression section is closer to the top of the outer ring than the first suppression section, and the second width L2 of the second suppression section is within this range. This results in a better suppression effect on high-temperature flue gas flow, extending the residence time of the high-temperature flue gas and allowing the energy-concentrating plate to radiate more heat towards the cookware, thereby improving thermal efficiency.

[0014] For example, the second suppressing section has a third end and a fourth end, forming a straight line segment between the third and fourth ends, and the second suppressing section forms an angle α with the mounting plane, the angle α being 0° to 20°. With this configuration, when the energy-concentrating plate is used in a cooking scenario, the angle α between the second suppressing section and the mounting plane is within this range. This not only makes the second suppressing section more effective at suppressing the outflow of high-temperature flue gas, but also extends the residence time of the high-temperature flue gas, allowing the energy-concentrating plate to radiate more heat towards the cookware, thereby improving thermal efficiency. Furthermore, it prevents the accumulation of broth, dust, and other dirt, making cleaning easier.

[0015] For example, the third end is closer to the top of the outer ring than the fourth end, and in the axial direction of the annular disc, the third end is not higher than the fourth end. With this configuration, when the energy-concentrating disc is used in cooking scenarios, the second suppression section is more effective in suppressing the outflow of high-temperature flue gas, and can prolong the residence time of high-temperature flue gas, allowing the energy-concentrating disc to radiate more heat towards the cookware, thereby improving thermal efficiency.

[0016] For example, there are at least two flue gas guiding sections, and a second suppression section is formed between two adjacent flue gas guiding sections; or, one of the at least two flue gas guiding sections is connected to the top of the outer ring to form an outer flue gas guiding section, and the second suppression section is connected to the end of the outer flue gas guiding section away from the top of the outer ring. With this configuration, when the energy-concentrating plate is used in a cooking scenario, the second suppression section suppresses the outflow of high-temperature flue gas, prolonging the residence time of high-temperature flue gas, allowing the energy-concentrating plate to radiate more heat towards the cookware; at the same time, based on the configuration of at least two arc-shaped flue gas guiding sections, not only is it difficult for soup or dust and other dirt to accumulate, making it easier to clean, but it also helps to focus radiated heat on the bottom of the pot, and can guide the high-temperature flue gas to flow closer to the surface of the bottom of the pot, making the bottom of the pot more evenly heated, reducing heat loss, and thus improving thermal efficiency.

[0017] For example, in the axial direction of the annular disc, the bottom end of the inner ring bends and extends away from the top end of the outer ring to form an extension section. With this configuration, the extension section bends and extends away from the top end of the outer ring. When the energy-concentrating disc is applied in a cooking scenario, it not only guides the high-temperature flue gas, but also prevents the extension section from approaching the flame of the burner, thus avoiding passive heating of the first suppression section and preventing a decrease in thermal efficiency.

[0018] For example, the annular disc includes an enclosing section that bends from the top of the outer ring towards the bottom of the inner ring, and the enclosing section, together with the flue gas guiding section and the flue gas suppressing section, forms a cavity; or, an enclosing body is provided below the annular disc, and the enclosing body, together with the annular disc, forms a cavity. With this configuration, when the energy-concentrating disc is used in a cooking scenario, it can concentrate heat at the center of the disc to heat the bottom of the pot, thus improving combustion efficiency.

[0019] According to another aspect of this utility model, a pot support is provided, which includes at least three legs and an energy-concentrating plate as described above, wherein the at least three legs are arranged circumferentially around the energy-concentrating plate. Since the energy-concentrating plate described above has the aforementioned beneficial effects, the pot support including the energy-concentrating plate also has the aforementioned beneficial effects, which will not be elaborated further here.

[0020] According to another aspect of this utility model, a gas stove is provided, which includes a burner and the aforementioned pot support, the pot support being sleeved outside the burner. Since the pot support described above has the aforementioned beneficial effects, the gas stove including the pot support described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0030] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0031] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0032] An embodiment of this utility model provides an energy-concentrating plate. This energy-concentrating plate can be applied to a pot support, which can be used in a gas stove. The following will describe in detail an energy-concentrating plate according to an embodiment of this utility model with reference to the accompanying drawings.

[0033] See also Figures 1 to 4 The energy-concentrating disk 10 may include an annular disk body 100. Understandably, a central hole 103 may be formed in the middle of the energy-concentrating disk 10, allowing the energy-concentrating disk 10 to be constructed as an annular disk body 100 with an inner ring and an outer ring. The annular disk body 100 may have an outer ring top end 101 and an inner ring bottom end 102, a flue gas guiding section 110, and a flue gas suppressing section 120. Both the flue gas guiding section 110 and the flue gas suppressing section 120 may be located between the outer ring top end 101 and the inner ring bottom end 102. The flue gas guiding section 110 has the function of radiating heat towards the cookware and guiding high-temperature flue gas to flow close to the bottom surface of the cookware. The flue gas suppressing section 120 has the function of suppressing the outflow of high-temperature flue gas. The flue gas suppressing section 120 may be connected to the end of the flue gas guiding section 110. In some embodiments, the connection between the flue gas suppression section 120 and the flue gas guiding section 110 may protrude or be recessed compared to the surface of the flue gas suppression section 120 and / or the surface of the flue gas guiding section 110, and the connection between the two also has a certain function of suppressing the outflow of high-temperature flue gas. The flue gas guiding section 110 may be constructed in an arc shape, in the axial direction of the annular disk 100 (e.g., Figure 3 and Figure 4 In the YY direction, the top of the outer ring 101 can be higher than the bottom of the inner ring 102, and the center of the flue gas guide section 110 can be higher than the top of the outer ring 101. For example... Figure 3 and Figure 4 The center A and center B of the flue gas guiding section 110 are both higher than the top of the outer ring 101. In other words, the annular disc 100 can be presented as having a higher outer surface and a lower inner surface, and a larger top and a smaller bottom.

[0034] The energy-concentrating plate 10 of this invention includes a smoke suppression section 120 and an arc-shaped smoke guide section 110. In the axial direction of the annular plate 100, the center of the smoke guide section 110 is higher than the top of the outer ring 101. When the energy-concentrating plate 10 is used in cooking, the smoke suppression section 120 suppresses the outflow of high-temperature smoke, extending the residence time of the high-temperature smoke, allowing the energy-concentrating plate 10 to radiate more heat towards the cookware. Simultaneously, the arc-shaped smoke guide section 110 prevents the accumulation of broth or dust, making cleaning easier. Furthermore, the fact that the center of the smoke guide section 110 is higher than the top of the outer ring 101 helps to reflect the high-temperature smoke upwards, thus focusing the radiated heat on the bottom of the pot. It also guides the high-temperature smoke to flow closer to the surface of the pot, resulting in more even heating of the pot bottom, reducing heat loss, and ultimately improving thermal efficiency.

[0035] See again Figures 1 to 4 From the bottom 102 of the inner ring to the top 101 of the outer ring, the annular disc 100 may have at least two sets of flue gas sections. Specifically, the annular disc 100 may have two sets of flue gas sections. Each set of flue gas sections may include a flue gas guiding section 110 and a flue gas suppressing section 120, and the connection point between the flue gas guiding section 110 and the flue gas suppressing section 120 in each set of flue gas sections may be the lowest point of the flue gas guiding section 110. In this way, the high-temperature flue gas can be guided to flow more effectively along the flue gas guiding section 110, making the flow of high-temperature flue gas smoother, avoiding the phenomenon of high-temperature flue gas becoming turbulent in the flue gas guiding section 110, and guiding the high-temperature flue gas to flow closer to the surface of the pot bottom, making the heating of the pot bottom more uniform, reducing heat loss, and thus improving thermal efficiency. In an embodiment not shown in the figure, from the bottom 102 of the inner ring to the top 101 of the outer ring, the annular disc 100 may have three sets of flue gas sections, etc.

[0036] See again Figures 1 to 4 In at least two groups of flue gas sections, the group closest to the bottom 102 of the inner ring is defined as the inner flue gas section group. In the direction parallel to the installation plane, the width of the inner flue gas section group can be greater than the width of the other flue gas section groups. Specifically, in the direction parallel to the installation plane, the width of the flue gas guide section 110 in the inner flue gas section group can be greater than the width of the flue gas guide section 110 in the other flue gas section groups. In an embodiment not shown in the figures, in the direction parallel to the installation plane, the width of the flue gas suppression section 120 in the inner flue gas section group can be greater than the width of the flue gas suppression section 120 in the other flue gas section groups. In the direction parallel to the installation plane, the widths of both the flue gas guide section 110 and the flue gas suppression section 120 in the inner flue gas section group can be greater than the widths of the flue gas guide section 110 and the flue gas suppression section 120 in the other flue gas section groups. In this way, the high-temperature flue gas can be guided to flow more effectively along the flue gas guide section 110, making the flow of high-temperature flue gas smoother. At the same time, the residence time of high-temperature flue gas is extended, which allows the energy-concentrating plate 10 to radiate more heat towards the cookware, reducing heat loss and thus improving thermal efficiency.

[0037] See again Figures 1 to 4 The flue gas suppression section 120 may include a first suppression section 121 extending from the bottom end 102 of the inner ring. That is, on the annular disc 100, the first suppression section 121 may be positioned close to the bottom end 102 of the inner ring. In a direction parallel to the mounting plane (e.g.) Figure 3 and Figure 4In the XX direction, the first suppression section 121 can have a first width L1, which can be 5mm to 15mm, for example, 5mm, 8mm, 10mm, or 15mm. The mounting plane direction and the axial direction of the annular disc 100 can be perpendicular. The mounting plane can be a horizontal plane, specifically the cooktop of the gas stove. It should be noted that in the initial stage of gas combustion, in order to initially mix the gas and air, the burner will first introduce a portion of air, called primary air. Primary air can enter the combustion zone through the burner's air inlet or mixing device, mix with the gas, and then undergo initial combustion. There are several ways for the burner to introduce primary air. For example, a mixing pipe can be provided between the burner's ejector tube and the nozzle tube, and an air inlet can be provided on the mixing pipe to introduce primary air; or, the burner can have an ejector tube, the middle section of which can have a smaller diameter. When the gas passes through the smaller diameter section (i.e., the throat) of the ejector tube, the velocity increases and the pressure decreases, thereby drawing in primary air. After the primary air supply, when the mixture of fuel gas and primary air begins to burn in the burner, an additional amount of air, called secondary air, is needed to ensure the continuous and stable combustion process and complete combustion of the fuel gas. The burner at least partially passes through the central hole 103 of the annular disc 100, and a secondary air channel (not shown in the figure) can be formed between the burner and the bottom end 102 of the inner ring, allowing the secondary air to smoothly enter the combustion zone and mix thoroughly with the fuel gas to ensure complete combustion. Since the first suppression section 121 extends from the bottom end 102 of the inner ring, when the secondary air flows in the secondary air channel, some of the secondary air will be suppressed at the first suppression section 121, allowing the secondary air to be preheated by the energy-concentrating disc 10. Thus, when the energy-concentrating plate 10 is applied in a cooking scenario, on the one hand, the first suppression section 121 extends from the bottom end 102 of the inner ring, suppressing secondary air and preheating it. This preheated air promotes more complete and intense combustion of the gas. On the other hand, the first width L1 of the first suppression section 121 is within this range, resulting in better suppression of high-temperature flue gas flow and a longer residence time for the flue gas. This allows the energy-concentrating plate 10 to radiate more heat towards the cookware and improves the suppression of secondary air, thereby enhancing thermal efficiency. This avoids the first width L1 of the first suppression section 121 being too large, which would block the secondary air passage and affect the amount of secondary air supplied. Conversely, it avoids the first width L1 of the first suppression section 121 being too small, which would fail to suppress the high-temperature flue gas and secondary air effectively. In one embodiment of this utility model, the first width L1 can be 10mm, so that the first suppression section 121 has a better effect in suppressing the outflow of high-temperature flue gas, can prolong the residence time of high-temperature flue gas, can make the energy-concentrating plate 10 radiate more heat toward the cookware, and has a better effect in suppressing secondary air, thereby improving thermal efficiency.

[0038] See also Figures 2 to 4 The first suppression section 121 may have a first end 1211 and a second end 1212. The first suppression section 121 may form an arc shape between the first end 1211 and the second end 1212. It should be noted that the arc shape can be a circular arc, a monotonously rising arc, or a gradually undulating arc that first descends and then rises sharply, etc. When the arc shape is a circular arc, the center of the arc is lower than the top 101 of the outer ring to achieve a better smoke suppression effect. In the axial direction of the annular disc 100 (e.g., ... Figure 3 and Figure 4 In the YY direction, the arc-shaped first suppression section 121 can be bent away from the top 101 of the outer ring. The second end 1212 can be configured as the bottom 102 of the inner ring. In this way, not only is the effect of suppressing secondary air and flue gas further improved, but the preheating time of the secondary air by the energy-concentrating plate 10 is also increased. The preheated air can promote more complete and more intense combustion of the gas, prolong the residence time of the high-temperature flue gas, and allow the energy-concentrating plate 10 to radiate more heat towards the cookware. It can also prevent the first suppression section 121 from being close to the flame of the burner, which would cause the flame to passively heat the first suppression section 121 and reduce the thermal efficiency.

[0039] In an embodiment not shown in the figure, the first suppression section 121 may have a first end 1211 and a second end 1212. The first suppression section 121 may form a straight line between the first end 1211 and the second end 1212. The second end 1212 may be configured as the bottom end 102 of an inner ring. In some embodiments, the straight first suppression section 121 may be inclined relative to the mounting plane. This not only further improves the effect of suppressing secondary air and flue gas, but also increases the preheating time of the secondary air by the energy-concentrating plate 10. The preheated air can promote more complete and intense combustion of the gas, prolong the residence time of the high-temperature flue gas, and allow the energy-concentrating plate 10 to radiate more heat towards the cookware. It can also prevent the first suppression section 121 from being close to the flame of the burner, which would cause the flame to passively heat the first suppression section 121 and reduce the thermal efficiency. Of course, it is also possible that the straight first suppression section 121 is arranged parallel to the mounting plane.

[0040] In an embodiment not shown in the figure, the first suppression section 121 may have a first end 1211 and a second end 1212. The first suppression section 121 may form a step shape between the first end 1211 and the second end 1212. The second end 1212 may be configured as the bottom end 102 of an inner ring. In some embodiments, the first suppression section 121 may have a first step surface and a second step surface, the first end 1211 may be disposed on the first step, the second end 1212 may be disposed on the second step, the first step surface may be perpendicular to the mounting plane or form a certain angle, and the second step surface may be parallel to the mounting plane. In this way, not only is the effect of suppressing secondary air and flue gas further improved, but the preheating time of the secondary air by the energy-concentrating plate 10 is also increased. The preheated air can promote more complete and more intense combustion of the gas, prolong the residence time of the high-temperature flue gas, and allow the energy-concentrating plate 10 to radiate more heat toward the cookware. It can also prevent the flame of the first suppression section 121 from being close to the burner flame, which would cause the flame to passively heat the first suppression section 121 and reduce the thermal efficiency.

[0041] See again Figures 2 to 4 The first end 1211 can be closer to the top end 101 of the outer ring than the second end 1212, in the axial direction of the annular disk 100 (e.g., Figure 3 and Figure 4 In the YY direction, the first end 1211 can be no lower than the second end 1212. That is, the plane parallel to the mounting plane where the first end 1211 is located can be higher than or equal to the plane parallel to the mounting plane where the second end 1212 is located. This improves the suppression of secondary air and flue gas, increases the preheating time of the secondary air by the energy-concentrating plate 10, and promotes more complete and intense combustion of the gas, prolonging the residence time of high-temperature flue gas and allowing the energy-concentrating plate 10 to radiate more heat towards the cookware. In the axial direction of the annular plate 100, when the second end 1212 is lower than the first end 1211, it prevents the first suppression section 121 from approaching the burner flame, thus avoiding passive heating of the first suppression section 121 by the flame and preventing a decrease in thermal efficiency. In embodiments not shown in the figure, the first end 1211 can also be lower than the second end 1212 to adapt to more application scenarios.

[0042] See again Figures 2 to 4 In the axial direction of the annular disk 100 (e.g. Figure 3 and Figure 4In the YY direction, there can be a height distance H between the first end 1211 and the second end 1212. The height distance H can be 3mm to 10mm, for example, 3mm, 5mm, 7mm, or 10mm. Within this range, the height distance H not only further enhances the suppression of secondary air and flue gas, but also increases the preheating time of the secondary air by the energy-concentrating plate 10. Preheated air promotes more complete and intense combustion of the gas, prolongs the residence time of high-temperature flue gas, and allows the energy-concentrating plate 10 to radiate more heat towards the cookware. It also prevents the first suppression section 121 from being too close to the burner flame, thus avoiding passive heating of the first suppression section 121 and a decrease in thermal efficiency. An excessively large height distance H avoids a significant reduction in the secondary air channel below the energy-concentrating plate 10, resulting in a decrease in secondary air supply. Conversely, an excessively small height distance H avoids poor suppression of secondary air and flue gas, and also avoids the first suppression section 121 being too close to the burner flame, thus avoiding passive heating of the first suppression section 121 and a decrease in thermal efficiency. In one embodiment of this utility model, the height distance H can be 5mm, which not only further improves the effect of suppressing secondary air and flue gas, but also increases the time for the secondary air to be preheated by the energy-concentrating plate 10. The preheated air can promote more complete and more intense combustion of the gas, prolong the residence time of the high-temperature flue gas, and allow the energy-concentrating plate 10 to radiate more heat toward the cookware. It can also prevent the flame of the first suppression section 121 from being close to the burner flame, which would cause the flame to passively heat the first suppression section 121 and reduce the thermal efficiency.

[0043] See again Figures 1 to 4 The flue gas suppression section 120 may include a second suppression section 122, which may be closer to the top edge 101 of the outer ring than the first suppression section 121, in a direction parallel to the mounting plane (e.g., Figure 3 and Figure 4In the direction of the first ring (XX direction), the second suppression section 122 can have a second width L2, which can be 5mm to 15mm, for example, 5mm, 8mm, 10mm, or 15mm. Thus, when the energy-concentrating plate 10 is applied in a cooking scenario, the second suppression section 122 is closer to the top of the outer ring 101 than the first suppression section 121. Since the second width L2 of the second suppression section 122 is within this range, the second suppression section 122 is more effective at suppressing the outflow of high-temperature flue gas and can prolong the residence time of high-temperature flue gas, allowing the energy-concentrating plate 10 to radiate more heat towards the cookware, thereby improving thermal efficiency. This avoids the second width L2 of the second suppression section 122 being too large, resulting in material waste and increased costs. It also avoids the second width L2 of the second suppression section 122 being too small, which would fail to suppress the high-temperature flue gas effectively. In one embodiment of this utility model, the second width L2 can be 10mm, the second suppression section 122 has a better effect in suppressing the outflow of high-temperature flue gas, and can prolong the residence time of high-temperature flue gas, so that the energy-concentrating plate 10 can radiate more heat toward the cookware, thereby improving thermal efficiency.

[0044] See again Figures 2 to 4 The second suppressing section 122 may have a third end 1221 and a fourth end 1222. A straight line segment may be formed between the third end 1221 and the fourth end 1222 of the second suppressing section 122. Furthermore, the second suppressing section may form an angle α with the mounting plane, which can be 0° to 20°, specifically 0°, 10°, 15°, or 20°. Thus, when the energy-concentrating plate 10 is applied in a cooking scenario, the angle α between the second suppressing section and the mounting plane falls within this range. This not only improves the suppression effect of the second suppressing section 122 on high-temperature flue gas flow but also extends the residence time of the high-temperature flue gas, allowing the energy-concentrating plate 10 to radiate more heat towards the cookware, thereby improving thermal efficiency. Moreover, it prevents the accumulation of broth, dust, and other dirt, making cleaning easier. In one embodiment of this invention, the included angle α can be 10°. The second suppressing section 122 has a better effect in suppressing the outflow of high-temperature flue gas and can prolong the residence time of high-temperature flue gas, allowing the energy-concentrating plate 10 to radiate more heat towards the cookware, thereby improving thermal efficiency. Moreover, it is not easy for soup or dust and other dirt to accumulate, making it easier to clean. In an embodiment not shown in the figure, the second suppressing section 122 can also form a stepped section or an arc section between the third end 1221 and the fourth end 1222. In this way, the second suppressing section 122 can suppress the outflow of high-temperature flue gas, prolong the residence time of high-temperature flue gas, and allow the energy-concentrating plate 10 to radiate more heat towards the cookware, thereby improving thermal efficiency.

[0045] See again Figures 2 to 4 The third end 1221 can be closer to the top of the outer ring 101 than the fourth end 1222, in the axial direction of the annular disk 100 (e.g., Figure 3 and Figure 4In the YY direction, the third end 1221 may not be higher than the fourth end 1222. That is, the plane parallel to the mounting plane where the third end 1221 is located may be lower than or equal to the plane parallel to the mounting plane where the fourth end 1222 is located. Thus, when the energy-concentrating plate 10 is applied in a cooking scenario, the second suppression section 122 is more effective at suppressing the outflow of high-temperature flue gas, and can prolong the residence time of high-temperature flue gas, allowing the energy-concentrating plate 10 to radiate more heat towards the cookware, thereby improving thermal efficiency. In an embodiment not shown in the figure, the third end 1221 may be higher than the fourth end 1222, and the second suppression section 122 can suppress the outflow of high-temperature flue gas, prolong the residence time of high-temperature flue gas, and allow the energy-concentrating plate 10 to radiate more heat towards the cookware, thereby improving thermal efficiency.

[0046] See again Figures 1 to 4 There can be at least two flue gas guiding sections 110, and the second suppression section 122 can be formed between two adjacent flue gas guiding sections 110. In this way, when the energy-concentrating plate 10 is used in a cooking scenario, the second suppression section 122 suppresses the outflow of high-temperature flue gas and prolongs the residence time of high-temperature flue gas, allowing the energy-concentrating plate 10 to radiate more heat towards the pot. At the same time, based on the setting of at least two arc-shaped flue gas guiding sections 110, not only is it difficult for soup or dust and other dirt to accumulate, making it easy to clean, but it also helps to focus radiated heat on the bottom of the pot, and can guide the high-temperature flue gas to flow closer to the surface of the bottom of the pot, making the bottom of the pot more evenly heated, reducing heat loss, and thus improving thermal efficiency.

[0047] Exemplarily, at least one of the two flue gas guiding sections 110 is connected to the top 101 of the outer ring to form an outer flue gas guiding section 110, and a second suppression section 122 is connected to the end of the outer flue gas guiding section 110 away from the top 101 of the outer ring. In some embodiments, multiple second suppression sections 122 may be provided between two adjacent flue gas guiding sections 110. Thus, when the energy-concentrating plate 10 is applied in a cooking scenario, the second suppression section 122 suppresses the outflow of high-temperature flue gas, prolonging the residence time of high-temperature flue gas, allowing the energy-concentrating plate 10 to radiate more heat towards the cookware; at the same time, based on the configuration of at least two arc-shaped flue gas guiding sections 110, not only is it difficult for broth or dust and other dirt to accumulate, making it easy to clean, but it also helps to focus radiated heat on the bottom of the pot, and can guide the high-temperature flue gas to flow closer to the surface of the bottom of the pot, making the bottom of the pot more evenly heated, reducing heat loss, and thus improving thermal efficiency. The number of flue gas guiding sections 110 and second suppression sections 122 is not specifically limited here, and can be adjusted according to the required thermal efficiency.

[0048] See again Figures 1 to 4A third suppression section 123 can be provided on the annular disc 100 near the top 101 of the outer ring. The third suppression section 123 can be connected to the side of the flue gas guide section 110 away from the outer ring. The third suppression section 123 can be a straight section, and the straight section of the third suppression section 123 can be parallel to the mounting plane. The end of the third suppression section 123 away from the flue gas guide section 110 can be configured as the top 101 of the outer ring. In this way, the third suppression section 123 can increase the velocity of the high-temperature flue gas and suppress the rapid outflow of high-temperature flue gas.

[0049] See again Figures 1 to 4 In the axial direction of the annular disk 100 (e.g. Figure 3 and Figure 4 In the YY direction, the bottom end 102 of the inner ring can be bent and extended away from the top end 101 of the outer ring to form an extension section 130. In some embodiments, an arc-shaped transition section 160 can be provided between the extension section 130 and the bottom end 102 of the inner ring to facilitate cleaning and avoid sharp shapes at the connection point that could scratch the user. Thus, with the extension section 130 bending and extending away from the top end 101 of the outer ring, when the energy-concentrating plate 10 is applied in a cooking scenario, it not only guides the high-temperature flue gas but also prevents the extension section 130 from getting too close to the burner flame, causing the flame to passively heat the first suppression section 121, thereby avoiding a decrease in thermal efficiency.

[0050] In some embodiments, see reference again Figures 1 to 4 An arc-shaped transition section 160 can be provided at the connection between the smoke suppression section 120 and the smoke guide section 110. That is to say, the smoke suppression section 120 and the smoke guide section 110 are connected by the arc-shaped transition section 160, which not only facilitates cleaning, but also prevents the sharp parts generated after the two are connected from scratching the user, thus improving safety.

[0051] In one embodiment of this utility model, see again in conjunction with the reference. Figures 1 to 4 The arc-shaped flue gas guide section 110 can have two sections, and a straight section 122 is provided between the two flue gas guide sections 110. The second suppression section 122 has a third end 1221 and a fourth end 1222. The third end 1221 is closer to the top of the outer ring 101 than the fourth end 1222. In the axial direction of the annular disk 100 (e.g., Figure 3 and Figure 4In the YY direction, the third end 1221 is lower than the fourth end 1222; one end of the two flue gas guiding sections 110, which is further away from the top of the outer ring 101, is connected to the arc-shaped first suppression section 121. The other end of the flue gas guiding section 110, which is closer to the top of the outer ring 101, is connected to the straight section third suppression section 123, which is parallel to the mounting plane. The end of the first suppression section 121 that is away from the flue gas guiding section 110 forms the bottom end 102 of the inner ring, which bends and extends away from the top of the outer ring 101 to form an extension section 130. The end of the third suppression section 123 that is away from the flue gas guiding section 110 forms the top of the outer ring 101. In this way, the flue gas can be suppressed by the first suppression section 121 and the second suppression section 122 to suppress the outflow of high-temperature flue gas, prolonging the residence time of high-temperature flue gas. This allows the energy-concentrating plate 10 to radiate more heat towards the pot. The first suppression section 121 can also suppress secondary air, and the extension section 130 has the function of guiding flue gas. The first suppression section 121 and the extension section 130 are set away from the flame of the burner to avoid the situation where the first suppression section 121 is passively heated and the combustion efficiency is reduced. The third suppression section 123 can increase the speed of high-temperature flue gas outflow and suppress the rapid outflow of high-temperature flue gas. At the same time, based on the arc-shaped flue gas guide section 110, not only is it difficult for soup or dust and other dirt to accumulate, making it easy to clean, but also, combined with the fact that the center of the flue gas guide section 110 is higher than the top of the outer ring 101, it is more conducive to focusing the radiated heat on the bottom of the pot. It can also guide the high-temperature flue gas to flow closer to the surface of the bottom of the pot, making the bottom of the pot heated more evenly, reducing heat loss, and thus improving thermal efficiency. In embodiments not shown in the figures, the number of flue gas suppression sections 120 and flue gas guiding sections 110 can be any suitable number, and the flue gas suppression sections 120 and flue gas guiding sections 110 can have various connection forms so that the energy-concentrating disk 10 can be applied to more scenarios.

[0052] See also Figures 1 to 3 The annular disc 100 may include an enclosing section 140, which bends from the top 101 of the outer ring towards the bottom 102 of the inner ring. The enclosing section 140, together with the flue gas guiding section 110 and the flue gas suppressing section 120, can form a cavity 150. In other words, the annular disc 100 is constructed as a double-disc structure with upper and lower sections. The enclosing section 140, the flue gas guiding section 110, and the flue gas suppressing section 120 can be a single integrated structure for ease of manufacturing. Thus, when the energy-concentrating disc 10 is used in cooking, it can concentrate heat at the center of the disc to heat the bottom of the pot, improving combustion efficiency.

[0053] In an embodiment not shown in the figure, an enclosing body is provided below the annular disc 100, and the enclosing body and the annular disc 100 enclose a cavity 150. That is, the annular disc 100 and the enclosing body constitute a double-disc structure arranged vertically. The enclosing body and the annular disc 100 can be separately installed, allowing the enclosing body to be installed or removed relative to the annular disc 100 for easy cleaning and maintenance. The enclosing body and the annular disc 100 can be connected by welding, screws, or other connection methods. Thus, when the energy-concentrating disc 10 is used in a cooking scenario, it can concentrate heat at the center of the energy-concentrating disc 10 to heat the bottom of the pot, improving combustion efficiency.

[0054] In some embodiments, see Figure 4 The annular disc 100 can be a single disc structure, which is simple in structure and easy to process and manufacture.

[0055] According to another aspect of this utility model, a pot support 1 is provided. (See also...) Figure 1 The pot support 1 may include at least three legs 20 and an energy-concentrating disk 10 as described above. The at least three legs 20 may be arranged circumferentially around the energy-concentrating disk 10. Specifically, each leg 20 may include a support portion 210 and a foot portion 220. The support portion 210 and the foot portion 220 may be an integral structure, which is convenient for processing and saves costs. Alternatively, the support portion 210 and the foot portion 220 may be separate structures. The support portion 210 may be connected to the upper surface of the annular disk 100, and the foot portion 220 may be connected to the lower surface, enclosure, or enclosure segment 140 of the annular disk 100. The support portion 210 may be connected to the upper surface of the annular disk 100 by welding or bonding. The foot portion 220 may be connected to the lower surface, enclosure, or enclosure segment 140 of the annular disk 100 by welding or bonding. Since the energy-concentrating plate 10 described above has the aforementioned beneficial effects, the pot support 1 including the energy-concentrating plate 10 described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0056] According to another aspect of this utility model, a gas stove is provided. The gas stove may include a burner and the aforementioned pot support 1, the pot support 1 being sleeved around the burner. Since the pot support 1 described above has the aforementioned beneficial effects, the gas stove including the pot support 1 also has the aforementioned beneficial effects, which will not be elaborated further here.
