Description

Technical Field

[0001] This application relates to the field of stove technology, and in particular to a pot support and a gas stove. Background Technology

[0002] A gas stove is a kitchen appliance that uses petroleum gas, manufactured gas, natural gas, or other gases as fuel for heating. The main components of the combustion system in a gas stove include the injector, the spray device, the burner head, and the burner cap. The pot support is a component in a gas stove used to support cooking utensils and transfer heat to them for faster heating.

[0003] However, the current pot supports have poor heat conduction, resulting in longer heating times for the cookware. Utility Model Content

[0004] This application addresses the problem of poor heat conduction in existing pot supports by proposing a pot support and a gas stove, which reduces heat loss and improves heat transfer efficiency.

[0005] A pot support, comprising:

[0006] The support leg extends in a first direction and has a bearing surface for supporting cooking utensils;

[0007] An energy-concentrating structure is installed on the support foot; the energy-concentrating structure has a clearance hole and at least two annular heat-insulating spaces, the clearance hole is directly opposite the burner head, and all the annular heat-insulating spaces are layered along the first direction and surround the outer periphery of the clearance hole.

[0008] With this design, the flame from the burner flows through the energy-concentrating structure to the cookware, heating it. As the flame flows through the clearance holes, some of the heat it carries diffuses outwards, heating the support legs and the energy-concentrating structure. Because the annular insulating space of the energy-concentrating structure surrounds the clearance holes, it blocks the heat as it diffuses outwards, slowing down the rate of heat loss and ensuring the pot support remains at a high temperature to transfer more heat to the cookware.

[0009] Secondly, since there are multiple annular insulation spaces, and all of them are distributed along the first direction, and since the heat itself diffuses upwards along the first direction, the annular insulation space near the bearing surface can not only block the heat diffused from the annular insulation space below it, but also block the heat flowing radially into the annular insulation space, further reducing heat loss and improving heat transfer efficiency.

[0010] In one embodiment, the energy-concentrating structure includes a first energy-concentrating ring, a second energy-concentrating ring, and a third energy-concentrating ring stacked along the first direction. Each of the first energy-concentrating ring, the second energy-concentrating ring, and the third energy-concentrating ring has a clearance hole in its middle. Along the first direction, an annular heat-insulating space is formed between adjacent pairs of the first energy-concentrating ring, the second energy-concentrating ring, and the third energy-concentrating ring.

[0011] As the flame flows from bottom to top along the first direction through different clearance holes, the annular heat-insulating spaces located at each clearance hole can block heat radially, reducing heat loss. Furthermore, the lower annular heat-insulating space blocks outward-diffusing heat, while the upper annular heat-insulating space further blocks and concentrates rising heat, thus reducing heat loss and ensuring the pot support remains at a high temperature, transferring significant heat to the cookware. The use of multiple heat-concentrating rings simplifies the structure and facilitates the formation of annular heat-insulating spaces.

[0012] In one embodiment, along the first direction, the inner edges of the first energy-concentrating ring, the second energy-concentrating ring, and the third energy-concentrating ring all protrude towards the bearing surface to form contact portions, and the corresponding contact portions of the first energy-concentrating ring, the second energy-concentrating ring, and the third energy-concentrating ring contact each other sequentially along the first direction.

[0013] When the first, second, and third energy-concentrating rings are assembled together, their contact portions are in contact in the first direction. This increases the contact area between the three rings, thereby improving the connection stability between them.

[0014] In one embodiment, the first energy-concentrating ring is disposed close to the bearing surface, and the outer edge of the first energy-concentrating ring is bent in a direction away from the bearing surface to form a limiting portion. The outer edges of the second energy-concentrating ring and the outer edges of the third energy-concentrating ring are connected to the limiting portion and are limited by the limiting portion to the radial direction of the clearance hole.

[0015] When the second and third energy-concentrating rings are heated or deformed radially along the clearance hole under the action of external force, the limiting part can limit the outer edge of the second and third energy-concentrating rings to reduce the probability that the outer edge of the second and third energy-concentrating rings will separate from the first energy-concentrating ring in the radial direction.

[0016] In one embodiment, the support foot passes through the annular insulation space, and part of the support foot is connected to the outer edge of the first energy-concentrating ring to form a heat-concentrating space.

[0017] With this configuration, the support foot is only connected to the outer edge of the first energy-concentrating ring, meaning that the two are not in complete contact. Moreover, the orthographic projection of the support foot in the first direction cannot cover the first energy-concentrating ring. Therefore, the heat-concentrating space formed between the support foot and the first energy-concentrating ring can communicate with the external environment of the clearance hole and the pot support.

[0018] During combustion, when the flame ejected from the burner flows to the vicinity of the heat-gathering space, the first energy-gathering ring wall and supporting feet of the heat-gathering space can prevent heat from diffusing outward, reducing heat loss. During this process, outside air can also enter the heat-gathering space and flow through the clearance holes, replenishing secondary air in a timely manner during combustion. This allows for more complete combustion, reduces carbon monoxide content, and improves the combustion efficiency of the fuel gas.

[0019] In one embodiment, there are multiple support feet, which are spaced apart around the clearance hole. Each support foot and the first energy-concentrating ring form a heat-concentrating space, and the heat-concentrating space and the annular heat-insulating space are arranged on the same side.

[0020] In this way, outside air can enter different heat-gathering spaces from different locations simultaneously, so as to replenish secondary air to the boiler support at different parts at the same time, thereby increasing the total amount of secondary air replenished to the boiler support per unit time, improving the combustion efficiency of the gas, and reducing the amount of carbon monoxide produced.

[0021] In one embodiment, the pot support further includes a heat insulation element disposed on the side of the support leg away from the bearing surface.

[0022] When the pot support is installed inside the gas stove, the support legs can be heated and transfer heat after the gas stove is turned on. For example, the support legs are installed above the drip tray via a heat insulation component, so the heat insulation component can block heat, reducing the heat transferred from the support legs to the drip tray. In other words, it reduces the heat transferred from the support legs to the vicinity of the heat insulation component, reducing the impact on components located near the heat insulation component.

[0023] In one embodiment, the heat insulation component has a slot, and the support leg has a buckle, which engages with the slot.

[0024] This design simplifies the structure of the support legs and the insulation components themselves, as well as the connection between them, making it easier to assemble and disassemble them.

[0025] In one embodiment, the surface of the thermal insulation element is covered with an anti-slip layer.

[0026] Placing the support feet of the heat insulation component on the placement surface increases the friction between the heat insulation component and the placement surface, improves the installation stability of the support feet, and thus improves the installation stability of the entire pot support.

[0027] Some embodiments of this application also provide a gas stove, including a burner and a pot support as described above, the pot support being disposed above the burner.

[0028] When the gas stove is turned on, the flame from the burner flows through the energy-concentrating structure to the cookware, heating it. As the flame flows through the clearance holes, some of the heat it carries diffuses outwards, heating the support legs and the energy-concentrating structure. Because the annular heat-insulating space of the energy-concentrating structure surrounds the clearance holes, it blocks the heat from diffusing outwards, slowing down the rate of heat loss and ensuring the pot support remains at a high temperature to transfer more heat to the cookware.

[0029] Because there are multiple annular insulation spaces, and all of them are distributed along the first direction, and the heat itself diffuses upwards along the first direction, the annular insulation space near the bearing surface can not only block the heat diffused from the annular insulation space below it, but also block the heat flowing radially into the annular insulation space, further reducing heat loss and improving heat transfer efficiency.

[0043] Please see Figures 1 to 3 In one embodiment of this application, a pot support 100 is provided, which includes a support leg 10 and an energy-concentrating structure 20. The support leg 10 extends along a first direction X and has a bearing surface 11 for supporting cookware; the energy-concentrating structure 20 is mounted on the support leg 10 and has a clearance hole 21 and at least two annular heat-insulating spaces 22. The clearance hole 21 is arranged directly opposite the burner head, and all the annular heat-insulating spaces 22 are layered along the first direction X and surround the outer periphery of the clearance hole 21.

[0044] The support leg 10 is used to mount the energy-concentrating structure 20 and to support the cookware. In other words, when the pot support 100 is installed above the burner, one end of the support leg 10 contacts the burner, and the other end of the support leg 10 has a bearing surface 11 on which the cookware can be placed. The burner head is positioned facing the clearance hole 21 of the energy-concentrating structure 20, and the flame emitted by the burner head can flow through the clearance hole 21 to the cookware to heat it. The support leg 10 and the energy-concentrating structure 20 can be made of the same material.

[0045] In actual use, the flame ejected by the burner flows through the energy-concentrating structure 20 to the cookware, heating it. As the flame flows through the clearance hole 21, some of the heat it carries can diffuse outwards, thereby heating the support leg 10 and the energy-concentrating structure 20. Because the annular heat-insulating space 22 of the energy-concentrating structure 20 is arranged around the clearance hole 21, as the heat of the flame continuously diffuses outwards, the annular heat-insulating space 22 can block the heat, reducing the rate of heat diffusion and thus reducing heat loss. This ensures that the pot support 100 is always at a higher temperature, so as to transfer higher heat to the cookware.

[0046] Secondly, since there are multiple annular insulation spaces 22, and all annular insulation spaces 22 are distributed along the first direction X, and since the heat itself diffuses upward along the first direction X, the annular insulation space 22 near the bearing surface 11 can not only block the heat diffused from the annular insulation space 22 below it, but also block the heat flowing radially into the annular insulation space 22, further reducing heat loss and improving heat transfer efficiency.

[0047] like Figure 2 As shown, in some embodiments, the energy-concentrating structure 20 includes a first energy-concentrating ring 23, a second energy-concentrating ring 24, and a third energy-concentrating ring 25 stacked along the first direction X. Each of the first energy-concentrating ring 23, the second energy-concentrating ring 24, and the third energy-concentrating ring 25 has a clearance hole 21 in its middle. Along the first direction X, an annular heat-insulating space 22 is formed between adjacent pairs of the first energy-concentrating ring 23, the second energy-concentrating ring 24, and the third energy-concentrating ring 25.

[0048] The first energy-concentrating ring 23, the second energy-concentrating ring 24, and the third energy-concentrating ring 25 can be connected together by welding. The depth of the internal grooves of the first energy-concentrating ring 23, the second energy-concentrating ring 24, and the third energy-concentrating ring 25 gradually increases. When the three are assembled together, the first energy-concentrating ring 23 and the second energy-concentrating ring 24 can be located inside the third energy-concentrating ring 25. Each of the first energy-concentrating ring 23, the second energy-concentrating ring 24, and the third energy-concentrating ring 25 has a clearance hole 21 in the middle. The clearance holes 21 of the three energy-concentrating rings are interconnected in the first direction X, and an annular heat-insulating space 22 is formed between two adjacent energy-concentrating rings. Therefore, the energy-concentrating structure 20 has two annular heat-insulating spaces 22 in the first direction X.

[0049] As the flame flows from bottom to top along the first direction X through different clearance holes 21, the annular heat-insulating spaces 22 located at different clearance holes 21 can block heat radially through the clearance holes 21, thereby reducing heat loss. The lower annular heat-insulating space 22 can block outwardly diffused heat, while the upper annular heat-insulating space 22 can further block and concentrate rising heat, thus reducing heat loss and ensuring that the pot support 100 remains at a high temperature, enabling it to transfer higher heat to the cookware. Furthermore, setting the energy-concentrating structure 20 as multiple energy-concentrating rings simplifies its structure and facilitates the formation of the annular heat-insulating spaces 22.

[0050] like Figure 3 As shown, in some embodiments, along the first direction X, the inner edges of the first energy-concentrating ring 23, the second energy-concentrating ring 24 and the third energy-concentrating ring 25 all protrude towards the bearing surface 11 to form contact portions 26, and the contact portions 26 of the first energy-concentrating ring 23, the second energy-concentrating ring 24 and the third energy-concentrating ring 25 contact each other sequentially along the first direction X.

[0051] For example, the inner edge of the first energy-concentrating ring 23 is provided with an annular contact portion 26, the inner edge of the second energy-concentrating ring 24 is provided with an annular contact portion 26, and the inner edge of the third energy-concentrating ring 25 is also provided with an annular contact portion 26. The contact portion 26 of each energy-concentrating ring can be provided to extend radially along the clearance hole 21.

[0052] When the first energy-concentrating ring 23, the second energy-concentrating ring 24, and the third energy-concentrating ring 25 are assembled together, their contact portions 26 are in contact in the first direction X. This increases the contact area between the three energy-concentrating rings 23, 24, and 25, thereby improving the connection stability among them.

[0053] Please continue reading. Figure 3 In some embodiments, the first energy-concentrating ring 23 is disposed close to the bearing surface 11, and the outer edge of the first energy-concentrating ring 23 is bent in a direction away from the bearing surface 11 to form a limiting part 231. The outer edges of the second energy-concentrating ring 24 and the outer edges of the third energy-concentrating ring 25 are connected to the limiting part 231 and are limited by the limiting part 231 to the radial direction of the clearance hole 21.

[0054] For example, such as Figure 3As shown, the outer edge of the first energy-concentrating ring 23 forms a flange in a direction away from the bearing surface 11, and this flange is configured as a limiting portion 231. Along the first direction X, one surface of the flange contacts the support foot 10, and the other surface of the flange contacts the outer edge of the second energy-concentrating ring 24 and the outer edge of the third energy-concentrating ring 25. Moreover, a portion of the limiting portion 231 can limit the outer edge of the second energy-concentrating ring 24 and the outer edge of the third energy-concentrating ring 25 in the radial direction of the clearance hole 21.

[0055] When the second energy-concentrating ring 24 and the third energy-concentrating ring 25 are heated or deformed radially along the clearance hole 21 under the action of external force, the limiting part 231 can limit the outer edge of the second energy-concentrating ring 24 and the outer edge of the third energy-concentrating ring 25 to reduce the probability that the outer edge of the second energy-concentrating ring 24 and the outer edge of the third energy-concentrating ring 25 will separate from the first energy-concentrating ring 23 radially.

[0056] In some embodiments, the support foot 10 passes through the annular heat-insulating space 22, and part of the support foot 10 is connected to the outer edge of the first energy-concentrating ring 23 to form a heat-concentrating space 12.

[0057] like Figure 2 As shown, the first energy focusing ring 23, the second energy focusing ring 24 and the third energy focusing ring 25 are all provided with through holes. The end of the support foot 10 away from the bearing surface 11 is inserted into the through holes of the first energy focusing ring 23, the second energy focusing ring 24 and the third energy focusing ring 25 in sequence to assemble the support foot 10 with the first energy focusing ring 23, the second energy focusing ring 24 and the third energy focusing ring 25.

[0058] Because the support foot 10 is only connected to the outer edge of the first energy-concentrating ring 23, that is, the two are not in complete contact, and the orthogonal projection of the support foot 10 in the first direction X cannot cover the first energy-concentrating ring 23, the heat-concentrating space 12 formed between the support foot 10 and the first energy-concentrating ring 23 can communicate with the external environment of the avoidance hole 21 and the pot support 100.

[0059] During combustion, when the flame ejected from the burner flows to the vicinity of the heat-concentrating space 12, the walls of the first energy-concentrating ring 23 and the supporting feet 10 of the heat-concentrating space 12 can prevent heat from diffusing outward, reducing heat loss. During this process, outside air can also enter the heat-concentrating space 12 and flow through it to the clearance hole 21, replenishing secondary air in a timely manner during combustion, resulting in more complete combustion, reduced carbon monoxide content, and improved combustion efficiency.

[0060] Please continue reading. Figure 2 In some embodiments, there are multiple support feet 10, which are spaced around the clearance hole 21. Each support foot 10 and the first energy-concentrating ring 23 form a heat-concentrating space 12, and the heat-concentrating space 12 and the annular heat-insulating space 22 are arranged on the same side.

[0061] For example, in Figure 2 In the example shown, the pot support 100 includes four support legs 10, which are spaced apart around the clearance hole 21. A heat-concentrating space 12 is formed between each support leg 10 and a different portion of the first energy-concentrating ring 23. All heat-concentrating spaces 12 are spaced apart circumferentially along the clearance hole 21; in other words, the lines connecting all the heat-concentrating spaces 12 can collectively form a ring, the orthographic projection of which in one direction falls within the annular insulation space 22.

[0062] In this way, outside air can enter different heat-gathering spaces 12 from different locations at the same time, so as to replenish the secondary air of the boiler support 100 at different parts of the boiler support 100 simultaneously, thereby increasing the total amount of secondary air replenished to the boiler support 100 per unit time, improving the combustion efficiency of the gas, and reducing the amount of carbon monoxide produced.

[0063] like Figure 2 and Figure 3 As shown, in some embodiments, the pot support 100 further includes a heat insulation element 30, which is disposed on the side of the support leg 10 away from the bearing surface 11.

[0064] The connection between the heat insulation component 30 and the support leg 10 can be, but is not limited to, a threaded connection, a snap-fit ​​connection, or other easy-to-disassemble method, so that if either the heat insulation component 30 or the support leg 10 is damaged, the damaged one can be replaced with a new one, which reduces maintenance costs compared to replacing both the heat insulation component 30 and the support leg 10.

[0065] When the pot support 100 is installed inside the gas stove, the support leg 10 can be heated and transfer heat after the gas stove is turned on. For example, the support leg 10 is installed above the liquid tray via a heat insulation member 30, so the heat insulation member 30 can block heat and reduce the heat transferred from the support leg 10 to the liquid tray. In other words, it reduces the heat transferred from the support leg 10 to the vicinity of the heat insulation member 30, reducing the impact on components located near the heat insulation member 30.

[0066] Specifically, such as Figures 3 to 5 As shown, in some embodiments, the heat insulation component 30 is provided with a slot 31, and the support foot 10 is provided with a buckle 13, which engages with the slot 31.

[0067] For example, such as Figure 4 As shown, the end of the support leg 10 furthest from the bearing surface 11 is recessed to form a buckle 13, and the end of the buckle 13 has a first protrusion. Figure 5As shown, the interior of the heat insulation component 30 is provided with a slot 31, and the groove wall of the slot 31 is also provided with a second protrusion. When the heat insulation component 30 and the support foot 10 are assembled together, the first protrusion of the support foot 10 is inserted into the slot 31 of the heat insulation component 30 to engage with the slot 31, and the second protrusion of the heat insulation component 30 extends into the groove of the support foot 10 and engages with it.

[0068] This design simplifies the structure of the support leg 10 and the heat insulation component 30, and also simplifies the connection between them, making it easier to assemble and disassemble them.

[0069] More specifically, the surface of the insulation element 30 is covered with an anti-slip layer.

[0070] The anti-slip layer can be detachably installed on the thermal insulation component 30, allowing for easy replacement of either the thermal insulation component 30 or the anti-slip layer. Alternatively, the anti-slip layer and the thermal insulation component 30 can be manufactured using a one-piece molding process.

[0071] When the support foot 10 of the heat insulation component 30 is placed on the placement surface, the friction between the heat insulation component 30 and the placement surface can be increased, thereby improving the installation stability of the support foot 10 and thus improving the installation stability of the entire pot support 100.

[0072] It should be noted that in some embodiments, the heat insulation component 30 itself can be made of anti-slip material, which eliminates the need for an additional anti-slip layer and simplifies the structure of the heat insulation component 30.

[0073] In addition, some embodiments of this application also provide a gas stove, which includes a burner and the pot support 100 in the above embodiments, the pot support 100 being disposed above the burner.

[0074] When the gas stove is turned on, the flame emitted by the burner flows through the energy-concentrating structure 20 to the cookware, heating it. As the flame flows through the clearance hole 21, some of the heat it carries can diffuse outwards, thereby heating the support leg 10 and the energy-concentrating structure 20. Because the annular heat-insulating space 22 of the energy-concentrating structure 20 is arranged around the clearance hole 21, as the heat from the flame continuously diffuses outwards, the annular heat-insulating space 22 can block the heat, reducing the rate of heat diffusion and thus minimizing heat loss. This ensures that the pot support 100 remains at a high temperature, transferring a higher level of heat to the cookware.

[0075] Because there are multiple annular insulation spaces 22, and all annular insulation spaces 22 are distributed along the first direction X, and the heat itself diffuses upward along the first direction X, the annular insulation space 22 near the bearing surface 11 can not only block the heat diffused from the annular insulation space 22 below it, but also block the heat flowing radially into the annular insulation space 22, further reducing heat loss and improving heat transfer efficiency.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
