Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas stoves, and in particular to a pot support and a gas stove including the pot support. Background Technology
[0002] Existing gas stoves utilize an energy-concentrating ring to improve thermal efficiency by constraining the flow path of flue gas. The high-temperature flue gas generated during combustion rises under the influence of thermal buoyancy. Part of the airflow is constrained by the energy-concentrating ring's inner wall guiding structure, such as an arc-shaped surface, causing the flue gas to flow along the wall. During this process, the flue gas remains within the energy-concentrating ring, forming an insulation layer. Furthermore, the metal wall of the energy-concentrating ring absorbs heat radiation and radiates it secondary to the cookware, thus concentrating heat and reducing heat loss to a certain extent, allowing the flame's heat energy to act more concentrated on the bottom of the cooking container.
[0003] In conventional energy-concentrating coils, there is a common problem of insufficient flue gas residence time. The structure inside the energy-concentrating coil is simple. Under the action of buoyancy, the high-temperature flue gas rises rapidly to the top of the energy-concentrating coil. The airflow quickly changes from laminar to turbulent and diffuses freely into the environment. As a result, the flue gas does not exchange heat fully with the bottom of the pot and directly escapes, causing significant heat loss.
[0004] Insufficient flue gas residence time leads to thermal efficiency loss. High-temperature flue gas loses heat before it is fully exchanged, resulting in reduced thermal energy utilization. This, in turn, shortens the heat storage time of the metal wall, weakens the contribution of radiative heat transfer, and particularly affects the fire stability under low-power conditions. In addition, it may also lead to incomplete secondary combustion. Unburned hydrocarbons and carbon monoxide cannot be completely oxidized due to insufficient residence time, increasing pollutant emissions. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defect of low heat utilization rate caused by short residence time of flue gas in the energy-concentrating ring in the prior art, and to provide a pot support and a gas stove including the pot support.
[0006] The present invention solves the above-mentioned technical problems through the following technical solution:
[0007] This utility model provides a pot support, the pot support including an energy-concentrating ring, the energy-concentrating ring having an annular structure, and a burner being disposed in the middle of the energy-concentrating ring. The energy-concentrating ring includes an arc-shaped wall panel and a partition. The arc-shaped wall panel has an opening facing the burner. The partition is disposed inside the arc-shaped wall panel, with its first end connected to the inner wall of the arc-shaped wall panel and its second end extending toward the opening to divide the interior of the arc-shaped wall panel into an upper vortex cavity and a lower energy-concentrating cavity. The length of the partition's vertical projection is less than the length of the arc-shaped wall panel. The second end of the partition points toward the upper edge of the arc-shaped wall panel to allow high-temperature flue gas to flow along the inner wall of the vortex cavity to form a vortex.
[0008] In this design, the pot support divides the energy-concentrating ring into upper and lower chambers via a partition. When high-temperature flue gas enters the interior of the curved wall panel through the opening and flows along its inner wall, it first resides in the lower energy-concentrating chamber, forming an insulation layer and achieving the basic effect of a conventional energy-concentrating ring. Since the second end of the partition points towards the upper edge of the curved wall panel, the high-temperature flue gas is then guided by the partition to the upper edge of the curved wall panel. Furthermore, the curvature of the curved wall panel itself causes the high-temperature flue gas to continue flowing along the inner wall of the vortex chamber, forming a vortex. This significantly increases the residence time of the high-temperature flue gas in the energy-concentrating ring, thereby significantly improving the utilization rate of the high-temperature flue gas heat and achieving overall energy-saving effects for the gas stove.
[0009] Preferably, the arc-shaped wall panel includes an upper curved plate and a lower curved plate, the starting ends of the upper curved plate and the lower curved plate are connected, and the ends of the upper curved plate and the lower curved plate extend toward the burner respectively, and the opening is provided between the two ends of the upper curved plate and the lower curved plate.
[0010] In this solution, the structure of the curved wall panel is specifically achieved through the above settings.
[0011] Preferably, the upper curved plate and the lower curved plate are connected and form a C-shape, and the upper curved plate and the lower curved plate are integrally formed.
[0012] In this design, the C-shaped upper and lower curved plates ensure a smooth transition of curvature on the inner wall of the curved panel, reducing the possibility of turbulence in the high-temperature flue gas during flow and making it easier for the high-temperature flue gas to form vortices, thereby improving the insulation effect. Furthermore, the lifting-body forming process enhances the overall strength of the curved panel.
[0013] Preferably, the upper curved plate and the lower curved plate are arranged symmetrically vertically.
[0014] In this scheme, the above-mentioned settings allow the ends of the upper and lower curved plates to be aligned due to the symmetrical arrangement, thereby improving the flow of high-temperature flue gas and enhancing the stability of the high-temperature flue gas flow.
[0015] Preferably, the partition is U-shaped, with one side of the U-shaped support being the first end connected to the inner wall of the arc-shaped wall panel, and the other side of the U-shaped support being the second end extending toward the opening.
[0016] In this scheme, the baffle that serves as the bottom wall of the vortex cavity is also curved, thereby enabling the high-temperature flue gas to form a vortex better and further improving the heat utilization rate of the high-temperature flue gas.
[0017] Preferably, there is one partition, with the first and second ends of the partition flush with the centerline in the height direction of the arc-shaped wall panel; or, there are multiple partitions, with the multiple partitions spaced apart in the arc-shaped wall panel along the height direction.
[0018] In this design, with only one baffle, aligning the first and second ends of the baffle with the centerline of the arc-shaped wall panel ensures that both the vortex cavity and the energy-concentrating cavity have ample space, even if the baffle is located in the middle region of the arc-shaped wall panel. This prevents one chamber from being too small, which could affect the flow of high-temperature flue gas and consequently impact heat utilization. Furthermore, with multiple baffles, the interior of the arc-shaped wall panel can be divided into multiple cavities, further increasing the residence time of the high-temperature flue gas and thus further improving heat utilization efficiency.
[0019] Preferably, the partition is welded to the arc-shaped wall panel.
[0020] In this design, welding can improve the connection strength between the partition and the curved wall panel.
[0021] Preferably, the pot support further includes a plurality of foot pieces arranged around the burner, the foot pieces being provided with grooves recessed in a direction away from the burner, and the energy-concentrating ring being disposed within the grooves.
[0022] In this design, placing the energy-concentrating ring within the groove reduces the possibility of ring wobbling, thereby improving the stability of the energy-concentrating ring connection.
[0023] Preferably, the energy-concentrating ring is welded to the plurality of foot plates.
[0024] In this design, welding can improve the connection strength between the energy-concentrating coil and the foot plate.
[0025] This utility model also provides a gas stove, which includes the pot support as described above.
[0026] In this design, the pot support divides the energy-concentrating ring into upper and lower chambers via a partition. When high-temperature flue gas enters the interior of the curved wall panel through the opening and flows along its inner wall, it first resides in the lower energy-concentrating chamber, forming an insulation layer and achieving the basic effect of a conventional energy-concentrating ring. Since the second end of the partition points towards the upper edge of the curved wall panel, the high-temperature flue gas is then guided by the partition to the upper edge of the curved wall panel. Furthermore, the curvature of the curved wall panel itself causes the high-temperature flue gas to continue flowing along the inner wall of the vortex chamber, forming a vortex. This significantly increases the residence time of the high-temperature flue gas in the energy-concentrating ring, thereby significantly improving the utilization rate of the high-temperature flue gas heat and achieving overall energy-saving effects for the gas stove.
[0027] The positive and progressive effects of this utility model are as follows:
[0028] This utility model discloses a pot support and a gas stove including it. A partition divides the energy-concentrating ring into upper and lower chambers. When high-temperature flue gas enters the interior of the arc-shaped wall panel through the opening and flows along the inner wall of the arc-shaped wall panel, it first stays in the lower energy-concentrating chamber, forming an insulation layer, achieving the basic effect of a conventional energy-concentrating ring. Since the second end of the partition points to the upper edge of the arc-shaped wall panel, the high-temperature flue gas is subsequently guided by the partition to the upper edge of the arc-shaped wall panel. Furthermore, the curvature of the arc-shaped wall panel causes the high-temperature flue gas to continue flowing along the inner wall of the vortex chamber, forming a vortex. This significantly increases the residence time of the high-temperature flue gas in the energy-concentrating ring, thereby significantly improving the utilization rate of the heat from the high-temperature flue gas and achieving an overall energy-saving effect for the gas stove.

[0047] Burner 2000; Detailed Implementation
[0048] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0049] like Figures 1 to 3 As shown, this embodiment provides a pot support 1000, which includes an energy-concentrating ring 1 and multiple foot pieces 2. The energy-concentrating ring 1 has a ring structure, and a burner 2000 is arranged in the middle of the energy-concentrating ring 1. The multiple foot pieces 2 are arranged around the burner 2000 and are used to support the pot. Figure 1 As shown, the number of foot pieces 2 is four, but those skilled in the art can adjust it according to actual conditions, and this embodiment is not limited. Each foot piece 2 includes a horizontally arranged abutment portion 201 for abutting the cookware and a vertically arranged support portion 202 connected to the abutment portion 201 for supporting the cookware. A C-shaped groove 203 is formed on the support portion 202 in a direction away from the burner 2000, and the energy-concentrating ring 1 is disposed within this groove 203. The placement of the energy-concentrating ring 1 within the groove 203 reduces the possibility of the energy-concentrating ring 1 wobbling, thereby improving the stability of the connection of the energy-concentrating ring 1.
[0050] like Figure 2 As shown, the energy-concentrating ring 1 includes an arc-shaped wall panel 101 and a partition 102. The arc-shaped wall panel 101 has an opening 103, which is an annular opening facing the burner 2000 and surrounding the burner 2000. The partition 102 is disposed inside the arc-shaped wall panel 101, with its first end connected to the inner wall of the arc-shaped wall panel 101 and its second end extending towards the opening 103 to divide the interior of the arc-shaped wall panel 101 into upper and lower chambers. The upper chamber is the vortex chamber 104, and the lower chamber is the energy-concentrating chamber 105. The vertical projection length of the partition 102 is less than the length of the arc-shaped wall panel 101, meaning that the second end of the partition 102 does not extend beyond the opening 103. The second end of the partition 102 points towards the upper edge of the arc-shaped wall panel 101 so that the high-temperature flue gas flows along the inner wall of the vortex chamber 104 to form a vortex. The second end of the baffle 102 pointing towards the upper edge of the arc-shaped wall panel 101 means that the slope of the second end of the baffle 102 points towards the upper edge of the arc-shaped wall panel 101. In other words, the extension line of the slope of the second end of the baffle 102 falls on the upper edge of the arc-shaped wall panel 101. Thus, when the high-temperature flue gas leaves the second end of the baffle 102, its movement along the slope of that end can be caught by the upper edge of the arc-shaped wall panel 101.
[0051] Thus, the pot support 1000 divides the energy-concentrating ring 1 into upper and lower chambers via the partition 102, such as... Figure 3As shown, the arrows indicate the flow path of the high-temperature flue gas. When the high-temperature flue gas enters the interior of the arc-shaped wall panel 101 through the opening 103 and flows along the inner wall of the arc-shaped wall panel 101, it first stays in the lower energy-concentrating cavity 105, forming an insulation layer to achieve the basic effect of a conventional energy-concentrating ring 1. Since the second end of the partition 102 points to the upper edge of the arc-shaped wall panel 101, the high-temperature flue gas is then guided by the partition 102 to flow towards the upper edge of the arc-shaped wall panel 101. Furthermore, the curvature of the arc-shaped wall panel 101 causes the high-temperature flue gas to continue flowing along the inner wall of the vortex cavity 104, forming a vortex. This significantly increases the residence time of the high-temperature flue gas in the energy-concentrating ring 1, thereby significantly improving the utilization rate of the high-temperature flue gas heat and achieving an overall energy-saving effect for the gas stove.
[0052] In this embodiment, as Figure 3 As shown, the arc-shaped wall panel 101 includes an upper curved plate 106 and a lower curved plate 107. The starting ends of the upper curved plate 106 and the lower curved plate 107 are connected, and their ends extend toward the burner 2000, respectively. An opening 103 is provided between the two ends of the upper curved plate 106 and the lower curved plate 107. Through the above arrangement, the structure of the arc-shaped wall panel 101 is specifically realized.
[0053] Furthermore, the upper curved plate 106 and the lower curved plate 107 are connected in a C-shape, and are integrally formed. The C-shape of the upper and lower curved plates 107 ensures a smooth transition of curvature on the inner wall of the arc-shaped wall panel 101, reducing the possibility of turbulence during the flow of high-temperature flue gas, making it easier for the high-temperature flue gas to form vortices, thereby improving the heat preservation effect. In addition, the integral forming process can improve the overall strength of the arc-shaped wall panel 101.
[0054] Furthermore, the upper bending plate 106 and the lower bending plate 107 are arranged symmetrically. This symmetrical arrangement allows the ends of the upper and lower bending plates 107 to be aligned, thereby improving the flow of high-temperature flue gas and enhancing its stability.
[0055] Specifically, such as Figure 3 As shown, the partition 102 is U-shaped. One side of the U-shaped support is connected to the inner wall of the arc-shaped wall panel 101 at the first end, and the other side of the U-shaped support is extended towards the opening 103 at the second end.
[0056] Thus, through the above-mentioned arrangement, the baffle 102, which serves as the bottom wall of the vortex cavity 104, also has an arc, thereby enabling the high-temperature flue gas to form a vortex better and further improving the heat utilization rate of the high-temperature flue gas.
[0057] Furthermore, such as Figure 2As shown, in this embodiment, there can be only one partition 102. The first and second ends of the partition 102 are flush with the centerline in the height direction of the arc-shaped wall panel 101. When there is only one partition 102, by making the first and second ends of the partition 102 flush with the centerline of the arc-shaped wall panel 101, even if the partition 102 is located in the middle area of the arc-shaped wall panel 101, it is ensured that both the vortex cavity 104 and the energy-concentrating cavity 105 have a large space, avoiding the situation where the space of one of the chambers is too small, which would affect the flow of high-temperature flue gas and thus affect the heat utilization effect.
[0058] In other embodiments, there are multiple partitions 102, which are spaced apart along the height direction within the arc-shaped wall panel 101. Multiple partitions 102 can divide the interior of the arc-shaped wall panel 101 into multiple cavities, thereby further increasing the residence time of the high-temperature flue gas and achieving a further improvement in heat utilization.
[0059] Furthermore, the partition 102 is welded to the arc-shaped wall panel 101. The welded connection can improve the connection strength between the partition 102 and the arc-shaped wall panel 101.
[0060] like Figure 4 As shown, this embodiment also provides a gas stove, which includes the pot support 1000 as described above.
[0061] Thus, the pot support 1000 divides the energy-concentrating ring 1 into upper and lower chambers via the partition 102. When the high-temperature flue gas enters the interior of the arc-shaped wall panel 101 through the opening 103 and flows along the inner wall of the arc-shaped wall panel 101, it will first stay in the lower energy-concentrating chamber 105 to form a heat insulation layer, achieving the basic effect of a conventional energy-concentrating ring 1. Since the second end of the partition 102 points to the upper edge of the arc-shaped wall panel 101, the high-temperature flue gas will then be guided by the partition 102 to the upper edge of the arc-shaped wall panel 101. In addition, the curvature of the arc-shaped wall panel 101 causes the high-temperature flue gas to continue to flow along the inner wall of the vortex chamber 104 to form a vortex, thereby significantly increasing the residence time of the high-temperature flue gas in the energy-concentrating ring 1, and thus significantly improving the utilization rate of the heat of the high-temperature flue gas, achieving the overall energy-saving effect of the gas stove.
