Description

Technical Field

[0001] The utility model relates to the technical field of kitchen utensils, and particularly to a pot support assembly and a gas stove. Background Art

[0002] During the actual use of the existing gas stove, the cookware is placed on the pot support assembly, and there is a certain space interval between the pot and the burner. In this way, in addition to heating the pot, a considerable part of the heat energy generated by the gas combustion escapes into the surrounding environment, resulting in energy waste.

[0003] In order to improve the combustion efficiency, in the prior art, the pot support assembly has a heat collecting plate formed by arranging upper and lower layers to form a cavity, and the support piece sequentially passes through the lower heat collecting plate, the cavity and the upper heat collecting plate to concentrate the heat emitted from the fire holes of the burner at the center position of the heat collecting plate. However, since the part of the support piece outside the cavity has a large contact area with the upper heat collecting plate, more heat is transferred, resulting in part of the heat loss, and this part of the heat may radiate downward, causing the installation panel below the lower heat collecting plate to heat up, thus causing the phenomenon of damage to the installation panel. Summary of the Utility Model

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present utility model, a pot support assembly is provided, and the technical solution is as follows.

[0005] The pot support assembly includes a first plate, a second plate and a support piece. The first plate and the second plate are arranged up and down and a cavity is formed between them. The first plate is provided with a first hole, and the support piece is connected to the first plate through the first hole. The support piece has a first part located outside the cavity, and the first part has an exposed bottom edge. The first plate has a top surface away from the second plate, and a heat insulation gap is formed between the exposed bottom edge and the top surface.

[0006] When the pot support assembly of the present utility model works in cooperation with the burner, a heat insulation gap is formed between the exposed bottom edge of the support piece and the top surface of the first plate, reducing the contact area between the support piece and the first plate, reducing heat transfer, thus effectively reducing heat loss, improving the combustion efficiency, and avoiding heat radiation downward, preventing the installation panel below the pot support assembly from heating up and causing the phenomenon of damage to the installation panel.

[0007] Exemplarily, the heat insulation gap is 1 mm to 2 mm. When the heat insulation gap is within this range, heat transfer is effectively reduced, and heat loss is reduced; it avoids poor heat insulation effect caused by too small a heat insulation gap and being unable to effectively reduce heat transfer, and avoids the reduction of the stability of the support piece for supporting the cookware caused by too large a heat insulation gap.

[0008] Exemplarily, the support piece further has a second part that extends into the cavity from the connection of the support piece and the first hole. The partial extension of the support piece into the cavity can make the connection between the support piece and the first disk more firm.

[0009] Exemplarily, a second hole is provided on the second disk, and the projection of the center of the second hole onto the installation plane coincides with the projection of the center of the first hole onto the installation plane, where the installation plane is a horizontal plane. Through the setting that the projection of the center of the second hole on the second disk onto the installation plane coincides with the projection of the center of the first hole on the first disk onto the installation plane, it is convenient to drill the first hole and the second hole during the processing.

[0010] Exemplarily, a footrest is connected to the second hole, and the footrest has an in-cavity part located in the cavity. By providing the footrest, the stability of the entire pot support assembly is improved, preventing the pot support assembly from shaking due to the weight of the cookware or external forces during use, and the partial extension of the footrest into the cavity can make the connection between the footrest and the second disk more firm.

[0011] Exemplarily, the second part has an inner bottom edge away from the exposed bottom edge, the in-cavity part has an inner top edge, and there is a spacing distance L between the inner bottom edge and the inner top edge. In this way, it is avoided that the support piece contacts the footrest, resulting in heat flowing from the support piece to the footrest and causing heat loss.

[0012] Exemplarily, there is a first connection point between the support piece and the first hole; there is a second connection point between the footrest and the second hole; there is a distance M between the first connection point and the second connection point, and the relationship between the spacing distance L1 and the distance M is: L1 ≤ M, and L1 ≥ 5 mm. When the spacing distance L1 between the inner bottom edge and the inner top edge is within this range, the firmness of the connection between the support piece and the first disk and the firmness of the connection between the footrest and the second disk are ensured, and heat loss caused by heat flowing from the support piece to the footrest is effectively avoided.

[0013] Exemplarily, the footrest has an outer bottom edge provided outside the cavity, the outer bottom edge is disposed opposite to the inner top edge, the second disk has a bottom surface away from the inner bottom edge, and there is a shortest distance H between the outer bottom edge and the bottom surface. In this way, an air channel is formed below the second disk through the footrest to facilitate the entry of air, so that the required secondary air for gas combustion can be supplemented.

[0014] Exemplarily, the shortest distance H is 10 mm to 12 mm. When the shortest distance H is within this range, the required secondary air for gas combustion can be effectively supplemented, avoiding that the shortest distance H is too small, resulting in too little supplemented secondary air, thus affecting the combustion efficiency, and avoiding that the shortest distance H is too large, that is, the footrest is too high, resulting in the shaking of the pot support assembly.

[0015] Exemplarily, the first disk has a first inner ring portion, and the second disk has a second inner ring portion. The first inner ring portion and the second inner ring portion are connected to form an energy-gathering inner ring portion with an inner ring. The energy-gathering inner ring portion is tilted upward relative to the installation plane to form an upward tilt angle γ, and the installation plane is a horizontal plane. The upward tilt of the energy-gathering inner ring portion can effectively prevent oil stains from flowing into the installation panel, thus facilitating user cleaning.

[0016] Exemplarily, the upward tilt angle γ is 15° to 25°. When the upward tilt angle γ of the energy-gathering inner ring portion is within this range, it can effectively prevent oil stains from flowing into the installation panel, avoid the upward tilt angle γ of the energy-gathering inner ring portion being too small, which may cause oil stains to flow into the installation panel along the energy-gathering inner ring portion, and avoid the upward tilt angle γ of the energy-gathering inner ring portion being too large, which increases the processing difficulty.

[0017] Exemplarily, the second inner ring portion has a first section that is inclined relative to the installation plane. The first section has a length D1, and the length D1 is 8 mm to 9 mm. When the length D1 of the first section is within this range, it can effectively prevent oil stains from flowing out of the energy-gathering inner ring portion.

[0018] Exemplarily, the first disk has a disk body and an outer ring wall. The outer ring wall extends from the end of the disk body away from the first inner ring portion towards the second disk. The outer ring wall has a length D2, and the length D2 is 10 mm to 14 mm. In this way, the cavity can be larger, which can more effectively insulate heat, reduce heat loss, and improve combustion efficiency.

[0019] Exemplarily, the disk body and the outer ring wall have an included angle α, and the included angle α is 90° to 100°. When the included angle α between the disk body and the outer ring wall is within this range, the cavity can be larger, which can more effectively insulate heat, reduce heat loss, and improve combustion efficiency.

[0020] Exemplarily, the disk body has a length D3, and the length D3 is 63 mm to 68 mm. When the length D3 of the disk body is within this range, the energy-gathering effect is better, and the combustion efficiency is improved.

[0021] Exemplarily, the second disk further has a second section and a third section connected to the second section. The second section is connected to the first section and is parallel to the installation plane. The third section is inclined from the end of the second section away from the first section towards the direction of the outer ring wall and is connected to the outer ring wall. In this way, the third section is designed to be inclined downward, so that the cavity can be larger, can more effectively insulate heat, reduce heat loss, and improve combustion efficiency; and by setting the second section parallel to the installation plane, an air passage is reserved.

[0022] Exemplarily, an included angle δ is formed between the second section and the third section, and the included angle δ is 150° to 160°. When the included angle δ between the second section and the third section is within this range, the cavity can be larger, heat loss is reduced, and combustion efficiency is improved.

[0023] Exemplarily, an included angle θ is formed between the third section and the outer ring wall, and the included angle θ is 80° to 95°. When the included angle θ between the third section and the outer ring wall is within this range, the cavity can be made larger, heat loss is reduced, and combustion efficiency is improved.

[0024] Exemplarily, the second section has a length D4, and the length D4 is 28 mm to 32 mm. When the length D4 of the second section is within this range, it is convenient for air to enter, and secondary air can be supplemented more smoothly during the combustion process.

[0025] Exemplarily, the third section has a length D5, and the length D5 is 34 mm to 36 mm. When the length D5 of the third section is within this range, the cavity is made larger, heat insulation can be more effective, heat loss is reduced, and combustion efficiency is improved.

[0026] According to another aspect of the present invention, there is provided a gas stove, including a burner and a pot support assembly. The first plate has a first inner ring portion, the second plate has a second inner ring portion, and the first inner ring portion and the second inner ring portion are connected to form an energy-gathering inner ring portion with an inner circle, and at least part of the burner passes through the inner circle. Since the pot support assembly as described above has the above beneficial effects, the gas stove including the pot support assembly as described above also has the above beneficial effects, which will not be repeated here one by one.

[0027] Exemplarily, the burner has an outer ring burner cap, the first plate has a plate body, and the outer wall surface of the plate body is inclined relative to the outer wall surface of the outer ring burner cap. In this way, it is possible to prevent the high-temperature flue gas after the burner burns from overflowing from all around, and it can effectively ensure that the high-temperature flue gas after combustion is directed upward. After fully exchanging heat with the bottom of the cookware, it is discharged, improving the thermal efficiency.

[0028] Exemplarily, there is an included angle η between the plate body and the outer wall surface of the outer ring burner cap, and the included angle η is 65° to 75°. When the included angle η between the plate body and the outer wall surface of the outer ring burner cap is within this range, it is possible to ensure that the high-temperature flue gas after combustion is directed upward. After fully exchanging heat with the bottom of the cookware, it is discharged, improving the thermal efficiency.

[0029] Exemplarily, a fire outlet hole is provided on the outer ring burner cap, and the center line of the fire outlet hole has an included angle β relative to the installation plane, and the included angle β is 19° to 20°. When the included angle β between the center line of the fire outlet hole and the installation plane is within this range, flame interference between the plate body and the fire outlet hole is avoided, which may cause the flue gas to rise.

[0030] Exemplarily, the fire outlet hole is higher than the energy-gathering inner ring portion. With such a setting, flame interference between the plate body and the fire outlet hole is further avoided, and the flame is prevented from burning the energy-gathering inner ring portion, which may cause the flue gas to rise.

[0031] Exemplarily, an oxygen replenishment channel is formed between the inner ring and the outer wall surface of the outer ring burner cap. The oxygen replenishment channel has a width L2, and the width L2 is 5 mm to 6 mm. In this way, it is ensured that the flame ejected from the flame outlet holes will not contact the inner ring, and the secondary air required for gas combustion can be supplemented through the oxygen replenishment channel, avoiding insufficient secondary air supplementation due to too small an oxygen replenishment channel, resulting in incomplete combustion. At the same time, it is also avoided that the oxygen replenishment channel is too large, resulting in excessive secondary air supplementation, causing the high-temperature flue gas after combustion to quickly overflow without sufficient heat exchange with the bottom of the cookware, resulting in heat loss.

[0032] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the specific implementation part. The utility model content part does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0043] In the following description, a large number of details are provided to enable a thorough understanding of the present utility model. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present utility model, and the present utility model can be implemented without one or more such details. In addition, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described in detail.

[0044] In order to thoroughly understand the implementation mode of the present utility model, detailed structures will be presented in the following description. Obviously, the implementation of the implementation mode of the present utility model is not limited to the special details familiar to those skilled in the art. The preferred implementation mode of the present utility model is described in detail as follows. However, in addition to these detailed descriptions, the present utility model can also have other implementation modes.

[0045] An embodiment of the present utility model provides a pot support assembly. The pot support assembly provided by the present utility model can be applied to a gas stove. The following will introduce in detail a pot support assembly according to an embodiment of the present utility model with reference to the accompanying drawings.

[0046] In order to understand the present utility model as a whole, the burner cooperating with the pot support assembly will be described first.

[0047] For a household gas stove, its burner usually has an outer ring burner cap, an inner ring burner cap and a pot support assembly. The outer ring burner cap and the inner ring burner cap form at least two rings of flames, thereby providing multiple flame modes when the user uses it. Correspondingly, the burner further includes a large-fire venturi and a small-fire venturi. The small-fire venturi is arranged at the center of the large-fire venturi. The outer ring burner cap and the inner ring burner cap are respectively covered on the large-fire venturi and the small-fire venturi, and the outer ring burner cap is located on the outer periphery of the inner ring burner cap. The large-fire venturi and the small-fire venturi are respectively connected to the large-fire venturi and the small-fire venturi. The large-fire venturi and the outer ring burner cap and the large-fire venturi form a large-fire mixing chamber. The small-fire venturi and the inner ring burner cap and the small-fire venturi form a small-fire mixing chamber. The gas stove usually further includes an installation panel, and the pot support assembly is installed on the installation panel and is arranged on the outer periphery of the outer ring burner cap to support the cookware.

[0048] Referring to Figures 1 to 5 , the pot support assembly 10 may include a first plate 110, a second plate 120 and a support piece 140. The first plate 110 and the second plate 120 may be arranged up and down, and a cavity 130 may be formed therebetween. When the pot support assembly 10 cooperates with the burner 20 to work, by setting the cavity 130, heat dissipation is effectively prevented, and the combustion efficiency of the burner 20 is improved. Specifically, the first plate 110 and the second plate 120 may be an integrally formed structure, or the first plate 110 and the second plate 120 may be fixed together by connection methods such as welding, buckling or pasting. A first hole 111 may be provided on the first plate 110. The support piece 140 is connected to the first plate 110 through the first hole 111, and the support piece 140 may have a first portion 141 located outside the cavity 130. The first hole 111 and the support piece 140 may be arranged in one-to-one correspondence, and the numbers of the two may be the same. The number of the support pieces 140 may be at least three, and the support pieces 140 may be arranged at intervals along the circumferential direction of the first plate 110 to ensure the stability of the pot support assembly 10 for supporting the cookware. It can be understood that at least three first holes 111 may be provided on the first plate 110, and the first holes 111 may be arranged at intervals along the circumferential direction of the first plate 110, so as to facilitate the connection between the first plate 110 and the support piece 140. Among them, the first portion 141 may be used to directly contact the bottom of the cookware and support the cookware. The first portion 141 may have an exposed bottom edge 143, that is, a side located outside the cavity 130 and away from the cookware. The first plate 110 may have a top surface 112 away from the second plate 120. An insulation gap 190 may be formed between the exposed bottom edge 143 and the top surface 112.

[0049] When the pot support assembly 10 of the present utility model works in cooperation with the burner 20, the heat insulation gap 190 formed between the exposed bottom edge 143 of the support piece 140 and the top surface 112 of the first plate 110 reduces the contact area between the support piece 140 and the first plate 110. Further reducing heat transfer, thus effectively reducing heat loss, improving combustion efficiency, and avoiding downward heat radiation, preventing the installation panel 30 from heating up and causing damage to the installation panel 30.

[0050] With reference to Figure 1 and Figure 2 , the heat insulation gap 190 can be 1 mm to 2 mm, that is, it can be represented by S being 1 mm to 2 mm. S can be the distance between the exposed bottom edge 143 and the tangent Y - Y' of the top surface 112. For example, the heat insulation gap 190 can be 1 mm, 1.5 mm, 2 mm, etc. When the heat insulation gap 190 is within this range, heat transfer can be effectively reduced, and heat loss is reduced; it avoids the situation where the heat insulation gap 190 is too small and the heat insulation effect is poor and cannot effectively reduce heat transfer, and also avoids the situation where the heat insulation gap 190 is too large, resulting in a reduction in the stability of the support piece 140 for supporting the pot. When the heat insulation gap 190 is 1.5 mm, the effect of reducing heat loss is the best, and the stability of supporting the pot is ensured.

[0051] Refer to Figure 1 and Figure 2 , the support piece 140 can also have a second part 142. The second part 142 extends into the cavity 130 from the connection part of the support piece 140 and the first hole 111. The support piece 140 can pass through the first hole 111 and be fixedly connected to the first plate 110 by welding. Of course, the support piece 140 can also be fixedly connected to the first plate 110 by connection methods such as snap - fitting and pasting. The support piece 140 partially extending into the cavity 130 can make the connection between the support piece 140 and the first plate 110 more firm, avoiding the support piece 140 from shaking when supporting the pot.

[0052] Refer to Figure 1 , Figure 2 and Figure 5 , a second hole 121 can be provided on the second plate 120. The projection of the center of the second hole 121 onto the installation plane can coincide with the projection of the center of the first hole 111 onto the installation plane. The installation plane can be a horizontal plane. Specifically, the installation plane can be the plane where the installation panel 30 is located. During the processing, it is convenient to drill the first hole 111 and the second hole 121. Of course, the projection of the center of the second hole 121 onto the installation plane and the projection of the center of the first hole 111 onto the installation plane can also partially coincide.

[0053] Refer to Figure 1 , Figure 2 and Figure 5, a footrest 160 may be connected to the second hole 121. By providing the footrest 160, the stability of the entire pot support assembly 10 is improved, preventing the pot support assembly 10 from shaking due to the weight of the cooking utensil or external forces during use. The footrest 160 and the second hole 121 may be provided in a one-to-one correspondence, and their numbers may be the same. There may be multiple footrests 160 to make the stability of the entire pot support assembly 10 higher. The footrest 160 may pass through the second hole 121 and be fixedly connected to the second plate 120 by welding. Of course, the footrest 160 may also be fixedly connected to the second plate 120 by connection means such as snap-fitting or pasting. The footrest 160 may have an inner cavity portion 161 located within the cavity 130. The partial insertion of the footrest 160 into the cavity 130 can make the connection between the footrest 160 and the second plate 120 more firm and not easily damaged. The portion of the footrest 160 located outside the cavity 130 may be placed on the installation plane. During processing, the support piece 140 and the footrest 160 may initially be integrally formed, and then the footrest 160 and the support piece 140 may be separated by cutting. During assembly, the support piece 140 is passed through the first hole 111 and connected to the first hole 111, and the footrest 160 is passed through the second hole 121 and connected to the second hole 121. In this way, the support piece 140 and the footrest 160 can be manufactured simultaneously, saving manufacturing materials and ensuring the vertical alignment of the footrest 160 and the support piece 140.

[0054] Of course, the processing and assembly can also be carried out in the following way. During processing, the support piece 140 and the footrest 160 can be processed integrally. During assembly, the integrally formed support piece 140 and footrest 160 are sequentially passed through the first hole 111 and the second hole 121 and respectively connected to the first hole 111 and the second hole 121, and then the footrest 160 and the support piece 140 are separated by cutting. It should be noted that when the above assembly is carried out, the first plate 110 and the second plate 120 have not been connected yet. In this way, not only is the assembly convenient, but also the vertical alignment of the footrest 160 and the support piece 140 after assembly is relatively high, enhancing the stability of the pot support assembly 10.

[0055] Referring to Figures 1 to 3 , the second part 142 may have an inner bottom edge 144 that is away from the exposed bottom edge 143. It can be understood that the inner bottom edge 144 may be located within the cavity 130 and the inner bottom edge 144 is closer to the second plate 120 than the exposed bottom edge 143. The inner cavity portion 161 may have an inner top edge 162. There is a spacing distance L1 between the inner bottom edge 144 and the inner top edge 162. In this way, contact between the support piece 140 and the footrest 160 is avoided, preventing heat from flowing from the support piece 140 to the footrest 160 and causing heat loss. The support piece 140 and the footrest 160 may be provided in a one-to-one correspondence. Of course, the situation where the numbers of the support piece 140 and the footrest 160 are inconsistent or they are staggered is not excluded.

[0056] Referring to Figures 1 to 3 , there may be a first connection point 151 between the support piece 140 and the first hole 111. The first connection point 151 may also be a point where any point on the hole wall of the first hole 111 is connected to the support piece 140. Preferably, the first connection point 151 may be the point on the hole wall of the first hole 111 that is closest to the cavity 130 and is connected to the support piece 140. There may be a second connection point 152 between the foot support 160 and the second hole 121. The second connection point 152 may also be a point where any point on the hole wall of the second hole 121 is connected to the foot support 160. Preferably, the second connection point 152 may be the point on the hole wall of the second hole 121 that is closest to the cavity 130 and is connected to the foot support 160. There may be a distance M between the first connection point 151 and the second connection point 152. The relationship between the spacing distance L1 and the distance M may be: L1 ≤ M, and L1 ≥ 5 mm. When the spacing distance L1 between the inner bottom edge 144 and the inner top edge 162 is within this range, the firmness of the connection between the support piece 140 and the first plate 110 and the firmness of the connection between the foot support 160 and the second plate 120 are ensured, and heat flowing from the support piece 140 to the foot support 160 is effectively avoided, resulting in heat loss.

[0057] Referring to Figures 1 to 5 , the foot support 160 may have an outer bottom edge 163 disposed outside the cavity 130. The outer bottom edge 163 and the inner top edge 162 may be oppositely disposed. The second plate 120 may have a bottom surface 122 away from the inner bottom edge 144. There may be a shortest distance H between the outer bottom edge 163 and the bottom surface 122. In this way, an air passage 50 is formed below the second plate 120 through the foot support 160 to facilitate air entry, so that the required secondary air can be supplemented for gas combustion. Specifically, the air passage 50 may be the distance between the bottom surface 122 and the mounting panel 30.

[0058] Referring to Figures 1 to 3 , the shortest distance H is 10 mm to 12 mm. For example, the shortest distance H may be 10 mm, 11 mm, 12 mm, etc. When the shortest distance H is within this range, the required secondary air can be effectively supplemented for gas combustion, avoiding the situation where the shortest distance H is too small, resulting in too little secondary air being supplemented, thus affecting the combustion efficiency, and avoiding the situation where the shortest distance H is too large, that is, the foot support 160 is too high, resulting in the shaking of the pot support assembly 10. When the shortest distance H is 10 mm, it is the best, which can effectively supplement the required secondary air for gas combustion, and the overall stability of the pot support assembly 10 is relatively high.

[0059] Furthermore, the outer bottom edge 163 of the foot support 160 may be connected to a rubber pad 180 for anti-skid. The rubber pad 180 may be fixed to the foot support 160 by a snap connection, or may be attached to the foot support 160 by an adhesive material. Of course, it is not excluded that the foot support 160 and the rubber pad 180 are connected by other connection methods. Since there is a spacing distance L1 between the bracket sheet 140 and the foot support 160, heat loss is reduced, and the rubber pad 180 is protected from high temperature, thereby preventing the rubber pad 180 from being deformed by heat and losing its anti-skid function.

[0060] See also Figures 1 to 5 , the shape of the first disk 110 and the second disk 120 can both be annular. Preferably, the shape of the first disk 110 and the second disk 120 can be circular. The first disk 110 can have a first inner ring portion 115. The second disk 120 can have a second inner ring portion 123. The first inner ring portion 115 can be connected with the second inner ring portion 123 to form an energy-gathering inner ring portion 170 having an inner ring 171. The energy-gathering inner ring portion 170 can be tilted relative to the mounting plane to form an upward tilt angle γ. The mounting plane can be a horizontal plane. Specifically, the first inner ring portion 115 and the second inner ring portion 123 can be arranged in parallel. A center line P-P' can be constructed on the energy-gathering inner ring portion 170, and the upward tilt angle γ can be constructed by the angle between the center line P-P' and the mounting plane. The upward tilt of the energy-gathering inner ring portion 170 can effectively prevent oil stains from flowing into the mounting panel 30. In this way, when cleaning the pot support assembly 10, the user can only clean the oil stains left on the energy-gathering inner ring portion 170, or simply clean the mounting panel 30 when cleaning the energy-gathering inner ring portion 170, which is convenient for the user to clean. In an embodiment not shown in the figure, the first inner ring portion 115 can form an upward angle γ with the mounting plane to effectively prevent oil stains from flowing into the mounting panel 30.

[0061] See also Figure 2 , Figure 4 and Figure 5 , the warping angle γ can be 15° to 25°. For example, the warping angle γ can be 15°, 20°, 25°, etc. When the warping angle γ of the energy-gathering inner ring portion 170 is within this range, it can effectively prevent oil stains from flowing into the installation panel 30, avoid the warping angle γ of the energy-gathering inner ring portion 170 being too small, causing oil stains to flow into the installation panel 30 along the energy-gathering inner ring portion 170, and avoid the warping angle γ of the energy-gathering inner ring portion 170 being too large, increasing the difficulty of processing. The optimal angle of the warping angle γ can be 20°, which has the best effect of preventing oil stains from flowing into the installation panel 30 and is easy to process.

[0062] See also Figures 4 to 6, the second inner ring part 123 may have a first section 124 which is inclined with respect to the mounting plane. The first section 124 may have a length D1. The length D1 may be 8 mm to 9 mm. For example, the length D1 may be 8 mm, 8.5 mm, 9 mm, etc., and the optimal length of the length D1 may be 8.5 mm. When the length D1 of the first section 124 is within this range, it can effectively prevent oil stains from flowing out of the energy-gathering inner ring part 170.

[0063] It can be understood that the included angle ω between the first section 124 and the mounting plane may also be 15° to 25°. For example, the included angle ω may also be 15°, 20°, 25°, etc. By arranging the first section 124 to be inclined, with a slight inclination for oxygen supply, the air can flow more smoothly towards the outer ring burner cap 210 of the burner 20, improving the secondary air supply, making the combustion more complete, reducing the emission of carbon monoxide while generating more heat, improving the thermal efficiency. Compared with other energy-gathering pot supports, this solution can supply secondary air more smoothly.

[0064] Refer to Figures 1 to 4 , the first plate 110 may have a plate body 113 and an outer ring wall 114. The outer ring wall 114 extends from one end of the plate body 113 away from the first inner ring part 115 towards the second plate 120. The outer ring wall 114 may have a length D2. The length D2 may be 10 mm to 14 mm. For example, the length D2 may be 10 mm, 12 mm, 14 mm, etc. In this way, the cavity 130 can be larger, which can insulate heat more effectively, reduce heat loss, and improve the combustion efficiency. The optimal length of the length D2 may be 12 mm, effectively reducing heat loss and improving the combustion efficiency.

[0065] Refer to Figure 2 and Figure 3 , the plate body 113 and the outer ring wall 114 may have an included angle α. The included angle α may be 90° to 100°. For example, the included angle α may be 90°, 95°, 100°, etc. When the included angle α between the plate body 113 and the outer ring wall 114 is within this range, the cavity 130 can be larger, which can insulate heat more effectively, reduce heat loss, and improve the combustion efficiency. The optimal angle of the included angle α may be 95°. It can effectively reduce heat loss and improve the combustion efficiency.

[0066] Refer to Figure 2 , Figure 3 and Figure 5, the disk body 113 may have a length D3. The length D3 may be 63 mm to 68 mm. For example, the length D3 may be 63 mm, 65 mm, 68 mm, etc. When the length D3 of the disk body 113 is within this range, the energy concentrating effect is better, and the combustion efficiency is improved. The optimal length of the length D3 may be 65 mm. At this time, the diameter of the disk body 113 is larger, which can effectively block the flame radiation, further reduce the temperature rise of the installation panel 30, and has the best energy concentrating effect, improving the combustion efficiency.

[0067] See Figures 1 to 4 , the second disk 120 may further have a second section 125 and a third section 126 connected to the second section 125. The second section 125 may be connected to the first section 124 and parallel to the installation plane. The third section 126 may be inclined from the end of the second section 125 away from the first section 124 toward the outer ring wall 114, and the third section 126 may be connected to the outer ring wall 114. In this way, the third section 126 is designed to slope downward, so that the cavity 130 can be larger, can insulate heat more effectively, further reduce the heat loss, and improve the combustion efficiency. By setting the second section 125 parallel to the installation plane, the air passage 50 is fully reserved, and the required secondary air for gas combustion can be effectively supplemented, improving the combustion efficiency.

[0068] See Figures 2 to 4 , an included angle δ may be formed between the second section 125 and the third section 126. The included angle δ may be 150° to 160°. For example, the included angle δ may be 150°, 155°, 160°, etc. When the included angle δ is within this range, the cavity 130 can be larger, the heat loss is reduced, and the combustion efficiency is improved. The optimal angle of the included angle δ may be 155°, which can make the cavity 130 larger, effectively reduce the heat loss, and improve the combustion efficiency.

[0069] See Figure 2 and Figure 3 , an included angle θ may be formed between the third section 126 and the outer ring wall 114. The included angle θ may be 80° to 95°. For example, the included angle θ may be 80°, 90°, 95°, etc. When the included angle θ is within this range, the cavity 130 can be larger, the heat loss is reduced, and the combustion efficiency is improved. The optimal angle of the included angle θ may be 90°, which makes the cavity 130 larger, effectively reduces the heat loss, and improves the combustion efficiency.

[0070] See Figures 2 to 4, the second section 125 may have a length D4. The length D4 is 28 mm to 32 mm. For example, the length D4 may be 28 mm, 30 mm, 32 mm, etc. When the length D4 of the second section 125 is within this range, air can enter conveniently, and secondary air can be supplemented more smoothly during the combustion process. The optimal length of the length D4 may be 30 mm, which is more convenient for air to enter, and secondary air can be supplemented more smoothly during the combustion process, thereby improving the combustion efficiency.

[0071] See also Figure 2 and Figure 3 , the third section 126 may have a length D5. The length D5 may be 34 mm to 36 mm. For example, the length D5 may be 34 mm, 35 mm, 36 mm, etc. When the length D5 of the third section 126 is within this range, the cavity 130 is made larger, heat insulation is more effective, heat loss is reduced, and combustion efficiency is improved. The optimal length of the length D5 may be 35 mm, which may make the cavity 130 larger, the heat insulation effect is optimal, heat loss is reduced, and combustion efficiency is improved.

[0072] See also Figures 1 to 5 According to another aspect of the present invention, a gas stove is provided. The gas stove may include a burner 20 and a pot support assembly 10. The first plate 110 may have a first inner ring portion 115, and the second plate 120 may have a second inner ring portion 123. The first inner ring portion 115 and the second inner ring portion 123 may be connected to form an energy-gathering inner ring portion 170 having an inner ring 171. The burner 20 may be at least partially penetrated through the inner ring 171. Since the pot support assembly 10 as described above has the above-mentioned beneficial effects, the gas stove including the pot support assembly 10 as described above also has the above-mentioned beneficial effects, which will not be described one by one here.

[0073] See also Figure 5 and Figure 6 The burner 20 may have an outer ring fire cover 210. The outer ring fire cover 210 has been described in detail above and will not be repeated here. The first plate 110 may have a plate body 113. The plate body 113 may be inclined relative to the outer wall surface 211 of the outer ring fire cover 210. In this way, the high-temperature flue gas after combustion of the burner 20 can be prevented from overflowing from all sides, and the high-temperature flue gas after combustion can be effectively guided upward, and it is discharged after sufficient heat exchange with the bottom of the cookware, thereby improving thermal efficiency.

[0074] See also Figure 5 and Figure 6, an included angle η may be formed between the disk body 113 and the outer wall surface 211 of the outer ring burner cap 210. The included angle η may be 65° to 75°. For example, the included angle η may be 65°, 70°, 75°, etc. When the included angle η is within this range, it can ensure that the high-temperature flue gas after combustion is directed upward, and after sufficient heat exchange with the bottom of the cookware, it is discharged, improving the thermal efficiency. The optimal angle of the included angle η may be 70°, and the effect of directing the high-temperature flue gas after combustion upward is the best. After sufficient heat exchange with the bottom of the cookware, it is discharged, improving the thermal efficiency.

[0075] Refer to Figure 5 and Figure 6 , the outer ring burner cap 210 may be provided with fire outlet holes 212. A center line Q-Q' may be constructed on the fire outlet holes 212, and the center line Q-Q' of the fire outlet holes 212 may have an included angle β relative to the installation plane. The included angle β may be 19° to 20°. For example, the included angle β may be 19°, 19.5°, 20°, etc. When the included angle β is within this range, flame interference between the disk body 113 and the fire outlet holes 212 is avoided, preventing the flue gas from rising. The optimal angle of the included angle β may be 19.5°, which has the best effect of avoiding flame interference between the disk body 113 and the fire outlet holes 212, and also avoids the rise of flue gas, thus preventing the high-temperature flue gas from escaping without sufficient heat exchange with the bottom of the cookware, improving the combustion efficiency.

[0076] Refer to Figure 5 and Figure 6 , only defining the angle of the center line of the fire outlet holes 212 cannot completely avoid flame interference during combustion. Further, the position of the fire outlet holes 212 may be higher than the energy-gathering inner ring portion 170. With this arrangement, flame interference between the disk body 113 and the fire outlet holes 212 is further avoided, preventing the flame from burning the energy-gathering inner ring portion 170 and causing the flue gas to rise.

[0077] Refer to Figure 5 and Figure 6 , an oxygen supply channel 40 may be formed between the inner ring 171 and the outer wall surface 211 of the outer ring burner cap 210. The oxygen supply channel 40 may have a width L2. The width L2 may be 5 mm to 6 mm. For example, the width L2 may be 5 mm, 5.5 mm, 6 mm, etc. In this way, it is ensured that the flame ejected from the fire outlet holes 212 will not contact the inner ring 171, and secondary air required for gas combustion can be supplemented through the oxygen supply channel 40. It is avoided that the oxygen supply channel 40 is too small, resulting in insufficient secondary air supply and incomplete combustion, and at the same time, it is avoided that the oxygen supply channel 40 is too large, resulting in excessive secondary air supply and rapid overflow of the high-temperature flue gas after combustion without sufficient heat exchange with the bottom of the cookware, causing heat loss. The optimal length of the length L2 may be 5.5 mm, which can ensure that the flame ejected from the fire outlet holes 212 will not contact the inner ring 171, and the amount of secondary air supplemented is most appropriate, ensuring the combustion efficiency.

[0078] Further, the gas stove may include an installation panel 30. By providing the installation panel 30, the interior of the gas stove is protected, preventing it from being affected by dust, water, etc., thereby reducing the safety risk. The installation panel 30 has been described above and will not be repeated here. Specifically, the installation panel 30 may be a glass panel. The glass panel is more convenient for users to clean. Of course, the case of using an installation panel 30 made of other materials is not excluded. Additionally, by providing the rubber pad 180, the footrest 160 can be effectively prevented from scratching the installation panel 30.

[0079] The gas stove may further include a drip tray 60. The drip tray 60 may be disposed between the pot support assembly 10 and the installation panel 30. The drip tray 60 can prevent food residues, grease, and other liquids from directly contacting the interior of the gas stove, reducing damage to the interior of the gas stove and being easy to clean. Only the drip tray 60 needs to be cleaned, rather than the entire installation panel 30. Specifically, the air passage 50 may also be supported by the drip tray 60 formed by the bottom surface 122 through the footrest 160 and / or the rubber pad 180 sleeved on the footrest 160.
