Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to a cookware support system and a gas stove with protective functions. Background Technology

[0002] A gas stove is a kitchen appliance that uses gaseous fuel for open-flame heating. It generates heat by burning gas to cook food and is a common appliance in home kitchens.

[0003] Existing gas stoves include key components such as ignition needles, flameout protection devices, and anti-dry-burning devices to improve the intelligence level of gas stoves. The performance of these key components is often easily affected by environmental factors such as oil stains, soup, or dirt generated during cooking. This can lead to functional problems such as ignition needles failing to discharge, flameout protection sensor malfunctioning, and anti-dry-burning system failure during operation. Once these functional problems occur, they can lead to serious safety accidents and cause a stove to become unusable or unstable during operation. Utility Model Content

[0032] Example See Figures 1 to 16 As shown in the figure, this application embodiment proposes a cookware support system with protective function. The cookware support system includes: a central support 1, at least two connecting parts 2, and a protective part 3. Protective component 3 is installed on the central support component 1; At least two connectors 2 are arranged along the circumferential direction of the central support 1 and extend along the radial direction of the central support 1, so that the at least two connectors 2 are radially distributed in the cookware support system to achieve stable support for the central support 1.

[0033] The central support 1 is located in the central area formed by at least two connectors 2, which support and suspend the protective member 3 above the flame outlet of the burner 93, so that the ignition needle 901 and / or flameout protection sensor 902 provided on the burner 93 are protected within the projection range covered by the protective member 3.

[0034] Understandably, at least two connectors 2 are distributed along the circumferential direction of the central support 1. The central support 1 is located in the central area, and the central support 1 is circumferentially connected to the connectors 2, thus achieving a radial layout for the entire cookware support system. The central support 1 is an important load-bearing component, used to support components such as the protective component 3. The connectors 2 are arranged circumferentially along the central support 1 and extend radially, which can disperse the load from the central support 1 and transfer it to the support points of each connector 2 through the connectors 2, avoiding stress concentration and improving the structural strength, reliability, and durability of the overall structure.

[0035] At least two connectors 2 provide multi-point support, increasing the support area of ​​the cookware support system and helping to maintain its stability. This multi-point support also adapts to different usage scenarios and cooktop panels 91 with varying smoothness, enhancing the versatility and adaptability of the cookware support system. Furthermore, compared to surface support, multi-point support creates a larger gap between the cookware support system or the bottom of the cookware and the cooktop panel 91, allowing airflow to pass through. This reduces the obstruction of fresh cold air or hot smoke by the cookware support system, promoting airflow circulation inside and outside the gas stove and thus ensuring the combustion efficiency of the gas stove.

[0036] Understandably, the connector 2 is used to support and suspend the protective component 3 above the burner 93's flame outlet. This not only protects the ignition needle 901 and / or the flameout protection sensor 902, but also prevents direct contact between the ignition needle 901 and / or the flameout protection sensor 902 due to collisions. Furthermore, it reduces the limitations on the usage scenarios or the functional implementation of the ignition needle 901 and / or the flameout protection sensor 902. For example, it avoids affecting the sensing and detection of the flameout protection sensor 902, ensuring that the flameout protection sensor 902 always maintains good accuracy and sensitivity.

[0037] The protective component 3 reduces the impact of environmental factors on key components such as the ignition needle 901, the flameout protection sensor 902, the flameout protection device, and the anti-dry-burning system, improving performance stability and ensuring the normal use of the gas stove. Specifically, the protective component 3 effectively shields these key components, reducing the corrosion of the ignition needle 901 and the flameout protection sensor 902 by oil, soup, or dirt during cooking. This reduces the risk of components losing their basic functions due to dirt accumulation, thereby extending the service life of the gas stove and enhancing its stability and safety during use.

[0038] Preferably, the connector 2 supports and suspends the protective member 3 in the center of the burner 93 flame outlet, thereby covering the ignition needle 901 and / or the flameout protection sensor 902 and protecting the ignition needle 901 and / or the flameout protection sensor 902.

[0039] Preferably, the protective element 3 is located at the center of the burner 93's flame outlet, protecting the ignition needle 901 and / or flameout protection sensor 902 located in the center of the burner 93 or its central channel, ensuring that the ignition needle 901 and / or flameout protection sensor 902 located in the central channel of the burner 93 are within the coverage area of ​​the protective element 3. Of course, there are no restrictions on the specific location of the ignition needle 901 and / or flameout protection sensor 902; the ignition needle 901 and / or flameout protection sensor 902 can be located in the edge area of ​​the burner 93.

[0040] like Figure 2 and Figure 4 As shown, in an optional embodiment, the central support member 1 is provided with a connecting groove 11 for connecting the protective member 3 and a support portion 12 for supporting the protective member 3. The support portion 12 is located in the axial direction of the central support member 1 and extends along the circumferential direction of the connecting groove 11.

[0041] Specifically, in some embodiments of this application, the overall shape of the connecting groove 11 and the supporting portion 12 is annular. Of course, the shapes of the connecting groove 11 and the supporting portion 12 described above are merely illustrative, intended to illustrate a possible implementation to aid in understanding the technical solution of this application. This application does not impose any limitations on the shape of the connecting groove 11 and the supporting portion 12; for example, they can be circular, square, polygonal, irregular, etc. In practical applications, the shapes of the connecting groove 11 and the supporting portion 12 can be adjusted according to actual needs, and all such adjustments should be covered within the protection scope of this application.

[0042] In an optional embodiment, preferably, as follows: Figures 1 to 4 As shown, a positioning element 13 is provided on the central support 1, which is used to realize the positioning connection between the central support 1 and the protective element 3.

[0043] Specifically, in some embodiments of this application, the positioning element 13 on the central support 1 can be a screw. Of course, the positioning element 13 can also be a positioning pin or a bolt. There are no restrictions on the specific implementation structure of the positioning element 13, as long as it satisfies the positioning function.

[0044] Understandably, the center support 1 is provided with a positioning element 13. The positioning element 13 helps to position and install the protective element 3, improving the assembly accuracy of the protective element 3. On the other hand, the positioning element 13 also further enhances the structural stability and reliability of the protective element 3 when connected to the center support 1.

[0045] Optionally, the cookware support system may be round, square, polygonal, or irregular in shape; however, there are no restrictions on the specific shape of the cookware support system.

[0046] Understandably, the connecting groove 11 restricts the installation position of the protective component 3, providing a reliable connection point and preventing radial displacement or offset of the protective component 3 after installation. The support portion 12 extends circumferentially along the connecting groove 11, increasing the support area of ​​the central support portion 1 on the protective component 3. The central support portion 1 and the protective component 3 are in full contact, generating a vertical support force on the protective component 3, thus improving the structural stability of the protective component 3 and the central support portion 1, and consequently increasing the load-bearing capacity of the central support portion 1. The cooperation between the connecting groove 11 and the support portion 12 also serves a guiding and positioning function, enabling the protective component 3 to be quickly aligned during installation. Furthermore, the connection groove 11 and the support portion 12 further enhance the connection stability between the protective component 3 and the central support portion 1. Specifically, the connecting groove 11 restricts the radial movement of the protective component 3, while the support portion 12 supports the protective component 3 and restricts its axial movement.

[0047] In an optional embodiment, combined with Figure 2 and Figure 4 As shown, the protective component 3 is a one-layer or multi-layer stacked structure; Optionally, the protective component 3 may be a structure composed of one or more of the following: microcrystalline plate, microcrystalline wafer, ceramic plate, ceramic sheet, high-temperature resistant glass plate, high-temperature resistant glass sheet, metal plate, metal sheet, high-temperature resistant insulating material plate, and high-temperature resistant insulating material sheet, stacked together.

[0048] Exemplary examples, in some embodiments of this application, such as Figures 4 to 6 , Figure 8 , Figure 9 , Figure 14 and Figure 16As shown, the protective component 3 can be one of the following: a single metal plate, a metal sheet, a microcrystalline plate, a microcrystalline wafer, a ceramic plate, a ceramic sheet, a high-temperature resistant glass plate, or a high-temperature resistant glass sheet. Alternatively, it can be a composite structure of any number of the following: metal plate, metal sheet, microcrystalline plate, microcrystalline wafer, ceramic plate, ceramic sheet, high-temperature resistant glass plate, high-temperature resistant glass sheet, high-temperature resistant insulating material plate, or high-temperature resistant insulating material sheet.

[0049] For example, such as Figure 2 As shown in the structure, protective component 3 can be made of microcrystalline wafers, metal sheets, or a composite structure of microcrystalline wafers and metal sheets. The microcrystalline wafers possess corrosion resistance, effectively resisting the erosion of contaminants such as oil and soup; the metal sheets possess good toughness and ductility, absorbing external impact energy through deformation to prevent component breakage. By complementing the properties of different materials, using the corrosion resistance of the microcrystalline wafers to isolate erosion, and the mechanical properties of the metal sheets to enhance structural stability, the overall physical properties of protective component 3 are significantly improved, making its protective capability superior to protective structures made of a single material.

[0050] Of course, the above content is only an example of the structure of protective component 3. There are no restrictions on the structure of protective component 3. It can be selected according to actual needs and should all be covered within the scope of protection of this application.

[0051] Understandably, the protective component 3 is made of a single piece of plate or sheet, which reduces the connection gaps and achieves better structural strength compared to a composite structure; while the protective component 3 is made of multiple plates or sheets stacked together, which helps to avoid the limitations of a single material and increases the functional characteristics of the protective component 3.

[0052] Specifically, in some embodiments of this application, when the protective component 3 is made of high-temperature resistant insulating material, it can achieve better stability and avoid adverse effects on the protective component 3 when the ignition needle 901 discharges.

[0053] In an optional embodiment, such as Figure 5 and Figure 6 As shown, the cookware support system also includes support component 4; The support member 4 is located at the end of the connector 2 away from the central support member 1.

[0054] Optionally, each connector 2 may be connected to one or more support members 4 at the end furthest from the central support member 1. Each connector 2 may be connected to one, two, three, or more support members 4. Of course, there is no limit to the number of support members 4 connected to each connector 2, as long as the support requirements of the cookware support system are met.

[0055] Optionally, a shock-absorbing and anti-slip pad 5 is provided at the end of the support member 4 that is away from the connector 2.

[0056] Understandably, the inclusion of a shock-absorbing and anti-slip pad 5, located at the end of the support member 4 opposite to the connector 2, enhances the stability and safety of the support member 4 and the cooktop panel 91. The shock-absorbing and anti-slip pad 5 effectively increases the friction of the contact surface, making the cookware support system less prone to displacement or sliding due to external forces or its own vibrations, thus reducing the risk of tipping over due to sliding.

[0057] Furthermore, flexible shock-absorbing and anti-slip pads 5 are added to the support 4 and the cooktop panel 91, which can reduce scratches and wear, help improve the durability of the cookware support system, and also protect the cooktop panel 91.

[0058] For example, in some embodiments of this application, the shock-absorbing and anti-slip pad 5 may be made of any one of rubber, silicone or polyurethane.

[0059] Of course, the materials of the shock-absorbing and anti-slip pad 5 described above are merely illustrative examples, intended to illustrate a possible implementation to aid in understanding the technical solution of this application. This application does not impose any limitations on the specific materials of the shock-absorbing and anti-slip pad 5. In practical applications, the materials of the shock-absorbing and anti-slip pad 5 can be adjusted according to actual needs, and all such adjustments should be covered within the scope of protection of this application.

[0060] Optionally, the central support 1 and the connecting part 2 are integrally formed, or the connecting part 2 and the support 4 are integrally formed, or the central support 1, the connecting part 2 and the support 4 are integrally formed.

[0061] The central support 1, connector 2 and support 4 can be set as separate parts, or partially or entirely integrally formed.

[0062] Understandably, a one-piece molding design can significantly improve the rigidity and stability of the overall structure, eliminate connection interfaces such as bolts and welds, allow forces to be transmitted along a more continuous and optimized path, reduce stress concentration points, thereby improving the load-bearing capacity and deformation resistance of the cookware support system as a whole, and also help to improve seismic performance.

[0063] In this case, adopting an integral molding design only between some components enhances the structural strength between these components. For example, it could be between the central support 1 and the connector 2, or between the connector 2 and the support 4. By strengthening these parts that mainly bear the support function through integral molding, the service life of the overall structure of the cookware support system can be extended. On this basis, adopting a separate design for some components can maintain the flexibility of assembly or combination to adapt to diverse usage needs.

[0064] In an optional embodiment, combined with Figures 6 to 12As shown, the cookware support system also includes an outer support member 6, and at least two connectors 2 are fixed to the outer support member 6.

[0065] Understandably, the outer support 6 can support the connector 2 and the central support 1, so that the central support 1 and the protective component 3 are suspended above the flame outlet of the burner 93, thus protecting the ignition needle 901 and / or the flameout protection sensor 902.

[0066] Specifically, in some embodiments of this application, the shape of the outer support member 6 includes cylindrical, frustum-shaped, annular, square, polygonal, irregular, etc., with the sidewall of the outer support member 6 serving as support, and the top of the outer support member 6 supporting the central support member 1.

[0067] In an optional embodiment, such as Figure 11 and Figure 12 The outer support member 6 shown includes several concentric and parallel annular disk structures 61.

[0068] Understandably, the outer support 6 includes several concentric and parallel annular disk structures 61, which can optimize load distribution and stress transmission, convert a concentrated load at a certain point into a stress that is uniformly distributed along the circumference, and transmit the force radially from the outside to the inside or from the inside to the outside by setting the annular disk structures 61 concentrically.

[0069] Furthermore, the outer support 6 stacks the annular disc structure 61 to form an approximately cylindrical space, which can also guide the airflow of the gas stove, allowing the hot flue gas to concentrate at the bottom of the pot and heat the pot, thereby improving the thermal efficiency of the gas stove.

[0070] In an optional embodiment, such as Figure 4 , Figure 9 and Figure 10 As shown, the connector 2 extends downward to form an extension 21, which connects to the annular disk structure 61 at its highest position of the outer support member 6; or, as Figure 7 and Figure 8 As shown, the end of the connector 2 away from the central support 1 is bent in a direction away from the central support 1 to form a bent portion 22, and the bent portion 22 is connected to the outer support 6. Optionally, the outer support 6 may be provided with a number of shock-absorbing and anti-slip pads 5 on the side facing away from the central support 1; or the bent part 22 may be provided with a shock-absorbing and anti-slip pad 5 on the end facing the burner 93.

[0071] Understandably, the extension 21 and / or the bend 22 increase the contact area between the connector 2 and the outer support 6, so that the connector 2 can be stably mounted on the outer support 6. At the same time, the extension 21 or the bend 22 can also expand the gap between the protective member 3 and the outer support 6 or the outer support 6 and the stove panel 91, thereby improving the passage capacity of hot flue gas and fresh cold air and facilitating the delivery of hot flue gas and fresh cold air.

[0072] The addition of a shock-absorbing and anti-slip pad 5, located on the side of the outer support 6 opposite to the central support 1, enhances the stability and safety of the outer support 6 and the cooktop panel 91. The shock-absorbing and anti-slip pad 5 effectively increases the friction of the contact surface, making the cookware support system less prone to displacement or sliding due to external forces or its own vibrations, thus reducing the risk of tipping over due to sliding.

[0073] In an optional embodiment, such as Figure 6 As shown, a support member 4 is provided in the circumferential direction of the outer support member 6 at the position corresponding to the connecting member 2, and the support member 4 is connected to the end of the connecting member 2 away from the central support member 1.

[0074] Understandably, the inclusion of support member 4 increases the contact area between the outer support member 6 and the connector 2, thereby strengthening the structural strength of connector 2 and improving its load-bearing capacity. The circumferential distribution of support member 4 along the outer support member 6 effectively disperses load and stress, enhancing the overall structural strength of the cookware support system and extending its service life.

[0075] Optionally, the outer support 6 may be provided with several shock-absorbing and anti-slip pads 5 on the side opposite to the central support 1.

[0076] As mentioned above, a shock-absorbing and anti-slip pad 5 is provided, and the shock-absorbing and anti-slip pad 5 is located on the side of the outer support 6 away from the central support 1, which can enhance the stability and safety of the outer support 6 and the stove panel 91.

[0077] Optionally, the central support 1, connector 2, support 4, and outer support 6 are integrally formed.

[0078] As mentioned above, the integrated design of the central support 1, connector 2, support 4 and outer support 6 can significantly improve the rigidity and stability of the overall structure, eliminate the connection interfaces such as bolts and welds, and allow forces to be transmitted along a more continuous and optimized path, reducing stress concentration points, thereby improving the load-bearing capacity and deformation resistance of the entire support structure, and also helping to improve seismic performance.

[0079] In an optional embodiment, such as Figures 13 to 16 As shown, the cookware support system also includes a heat-insulating, flow-guiding, and refractive element 7; The heat-insulating flow-guiding and refraction element 7 is connected to the support element 4 and is located in the area below the support element 4. The heat-insulating flow-guiding and refraction element 7 is suspended above the flame outlet of the burner 93 or in the outer area of ​​the burner 93 by the support of the support element 4.

[0080] For example, in some embodiments of this application, the heat-insulating flow-guiding and refraction member 7 can be suspended directly above the burner 93, or suspended in the outer area of ​​the burner 93, or suspended simultaneously above and in the outer area of ​​the burner 93. That is, the heat-insulating flow-guiding and refraction member 7 covers the burner 93 and the outer area of ​​the burner 93.

[0081] Of course, the above content is only some examples of the relative positions of the heat insulation and flow guiding reflector 7 and the burner 93. There are no restrictions on the specific position of the heat insulation and flow guiding reflector 7. The specific position of the heat insulation and flow guiding reflector 7 can be selected according to actual needs, and all should be covered within the protection scope of this application.

[0082] Understandably, one end of the cookware support system is used to support the cookware, and the other end is used to connect to the cooktop panel 91. The cookware support system is set on the cooktop panel 91, and the cookware is set on the cookware support system, which can maintain the stability of the relative position of the cookware and the cooktop panel 91. Furthermore, the heat insulation and flow guiding reflector 7 is connected to the support member 4 or the connector 2. The heat insulation and flow guiding reflector 7 is suspended above or in the outer area of ​​the burner 93, which also makes the distance between any two of the cookware, the cooktop panel 91 and the heat insulation and flow guiding reflector 7 stable, thereby maintaining the hot flue gas delivery distance 71 and the fresh cold air circulation channel within a preset size range, enhancing the stability and reliability of the functions of the hot flue gas emission channel and the fresh cold air circulation channel.

[0083] Combination Figures 13 to 19 As shown, the upper end face of the heat insulation and flow guiding reflector 7 is used to form a hot flue gas conveying gap 71 between itself and the bottom of the pot, and the hot flue gas conveying gap 71 constitutes a hot flue gas emission channel. The lower end face of the heat insulation and airflow deflector 7 is used to provide a fresh cold air circulation channel between itself and the stove panel 91. The fresh cold air circulation channel is used to supplement the fresh cold air required for combustion to the air intake end of the burner 93.

[0084] Understandably, the heat-insulating and flow-guiding refractor 7 divides the space between the bottom of the cookware and the cooktop panel 91 into a hot flue gas exhaust channel and a fresh cold air circulation channel, realizing the directional separation and transportation of hot flue gas and fresh cold air. This effectively avoids mutual disturbance of gas flow between hot flue gas and fresh cold air, and reduces direct contact and heat exchange between them. Furthermore, the thermo-pressure effect formed by the pressure difference between fresh cold air and hot flue gas promotes the orderly discharge of hot flue gas and the orderly replenishment of fresh cold air, allowing hot flue gas and fresh cold air to flow alternately. This replenishes the bottom shell 92 with fresh cold air, increasing the gas turnover rate inside the gas stove and forming an internal and external circulation of hot and cold air. This, in turn, promotes the complete combustion of the burner 93 and reduces exhaust emissions, thereby improving the thermal efficiency of the gas stove.

[0085] The hot flue gas exhaust channel formed between the upper surface of the heat-insulating and flow-guiding refractor 7 and the bottom of the pot allows the hot flue gas generated by the burner 93 during combustion to flow from above the burner 93 through the bottom of the pot, and then be transported radially along the bottom of the pot to the outer edge before being discharged. In this process, the flow velocity of the hot flue gas is suppressed, which slows down the flow rate of the hot flue gas. By controlling the flow velocity, the heat exchange time at the bottom of the pot is extended, allowing the pot to absorb the heat energy released by the burner 93 during combustion to the maximum extent. In addition, the hot flue gas can also be converted into infrared radiation heat energy by the heat-insulating and flow-guiding refractor 7 and refracted back to the bottom of the pot in the form of infrared heat radiation, forming multiple heating of the bottom of the pot, which fully improves the utilization rate of the hot flue gas heat energy, thereby further improving the thermal efficiency of the gas stove.

[0086] In addition, as mentioned above, reducing the direct contact and heat exchange between hot flue gas and fresh cold air also reduces the loss of heat energy from the hot flue gas, which can also improve the thermal efficiency of gas stoves to a certain extent.

[0087] The lower end face of the heat-insulating and air-guiding reflector 7 forms a fresh cold air circulation channel with the cooktop panel 91, which helps fresh cold air to flow smoothly through the lower end face of the heat-insulating and air-guiding reflector 7 and enter the bottom shell 92 and the surface of the burner 93. This replenishes the surface of the burner 93 and the air inlet of the injector tube 932 with fresh cold air. Through the replenishment of fresh cold air in a double layer, the burner 93 achieves complete combustion, which promotes the improvement of the thermal efficiency of the gas stove and the emission of exhaust gas.

[0088] In addition, as mentioned above, the effective avoidance of mutual mixing and disturbance between hot flue gas and fresh cold air improves the gas turnover rate inside the gas stove, and the orderly replenishment of fresh cold air can avoid the problem of intermittent lack of fresh cold air. This effectively improves the air convection environment required by the burner 93 during the combustion process, thereby reducing incomplete combustion and improving the stability and reliability of the burner 93 during the combustion process.

[0089] Figure 18 and Figure 19 The arrows indicate the direction of hot flue gas flow or the direction of fresh cold air flow. That is, it is a brief illustration of the location of the hot flue gas emission channel and the fresh cold air circulation channel. The airflow flowing outward in the upper area is hot flue gas, and the airflow flowing inward in the lower area is fresh cold air.

[0090] In an optional embodiment, such as Figure 15 , Figure 16 , Figure 20 and Figure 21 As shown, the cookware support system also includes a heat-conducting component 8; The heat-conducting component 8 is used to absorb the heat generated by the burner 93 and conduct the heat to the pot located on the upper surface of the heat-conducting component 8, thereby heating the pot and cooking the food. The heat-conducting component 8 is connected above the connector 2 and covers the protective component 3 so that the ignition needle 901 and / or the flameout protection sensor 902 provided on the burner 93 are protected within the projection range covered by the heat-conducting component 8 and the protective component 3. The upper end face of the heat-conducting component 8 is used to support the cookware. The upper end face of the heat-insulating and flow-guiding refraction component 7 and the lower end face of the heat-conducting component 8 form a hot flue gas conveying gap 71, which constitutes a hot flue gas emission channel.

[0091] Specifically, in some embodiments of this application, the heat-conducting element 8 can directly receive the heat from the burner 93 and conduct it to its own top surface, forming a surface contact with the bottom of the cookware. Compared to the point or line contact formed by the energy-concentrating plate and the pot support in traditional stoves, this surface contact structure not only increases the contact area and enhances the stability of the cookware, but also completely changes the suspended state of the cookware, reducing the risk of the cookware slipping or tipping over, and greatly improving the safety of use; at the same time, the absence of an energy-concentrating plate and the simplified structure of the pot support avoid the cleaning problem of dirt accumulating in the gaps of traditional energy-concentrating plates, greatly improving cleaning efficiency and the overall aesthetics of the stove.

[0092] Furthermore, the upper end face of the heat insulation and flow guiding refraction component 7 and the lower end face of the heat conducting component 8 form a hot flue gas conveying gap 71, which can further enhance the control of the flow direction and flow rate of the hot flue gas, avoid the disorderly flow of the hot flue gas. In the hot flue gas emission channel formed by the hot flue gas conveying gap 71, the hot flue gas flows outward evenly along the radial direction of the heat conducting component 8, so that the heating effect of the gas stove on different areas of the bottom of the pot is more consistent, thereby reducing the situation of burning the pot to a certain extent.

[0093] For example, the shape of the heat-conducting element 8 includes a disc, plate, or sheet, and it can be made of high-quality thermally conductive organic or inorganic materials. Specifically, the heat-conducting element 8 can be made of metal or non-alloy materials with a small range of thermal stress changes, or it can be made of microcrystalline plates, quartz plates, or glass and metal materials with high temperature resistance and excellent thermal conductivity.

[0094] Of course, the above content is merely an example of the shape and material of the heat-conducting component 8, intended to illustrate a possible implementation to aid in understanding the technical solution of this application. No limitations are imposed on the shape and material of the heat-conducting component 8; it can be selected according to actual needs and should all be covered within the scope of protection of this application.

[0095] Specifically, in some embodiments of this application, the heat-conducting element 8 is a circular plate structure, namely a heat-conducting plate. The heat-conducting plate increases the direct contact area between the heat efficiency improvement device and the cookware, has a better bearing capacity, and can play the role of supporting the cookware. This makes the cookware more stable when placed on the upper surface of the heat-conducting plate, and less prone to side slipping or tipping.

[0096] The heat-conducting component 8 can cover the ignition needle 901, the flameout protection sensor 902, and even the entire burner 93, effectively isolating the burner 93 from external environmental interference. The heat-conducting component 8 and the protective component 3 work together to form a dual-protection structure: the protective component 3 primarily provides direct protection from directly above, focusing on protecting the ignition needle 901 and the flameout protection sensor 902; the heat-conducting component 8 provides all-around protection, filling the gaps in the protective direction provided by the protective component 3, further enhancing the safety of the gas stove during use.

[0097] In an optional embodiment, the surfaces of the heat-conducting component 8, the protective component 3, and the heat-insulating and flow-guiding refraction component 7 are planar or curved. A flat surface is one with a smooth design and no obvious undulations, while a curved surface has a curvature and obvious undulations.

[0098] For example, taking the heat-conducting component 8 as an example, refer to Figures 22 to 24 and Figure 28 As shown, the surface of the heat-conducting component 8 is a planar design, referring to... Figures 25 to 27 and Figure 29As shown, the surface of the heat-conducting component 8 is a curved surface design.

[0099] Taking protective component 3 as an example, refer to Figures 30 to 33 As shown, the surface of the protective component 3 is designed as a flat surface. Of course, the surface of the protective component 3 can also be designed as a curved surface.

[0100] Preferably, the surfaces of the heat-conducting component 8 and / or the protective component 3 and / or the heat-insulating and flow-conducting refractive component 7 are provided with protrusion structures 81; For example, such as Figure 23 , Figure 24 , Figure 26 , Figure 27 , Figure 28 and Figure 29 As shown, the surface of the heat-conducting component 8 has a bump structure 81 distributed thereon, such as Figures 31 to 33 As shown, the protective component 3 has a raised dot structure 81 distributed on its surface.

[0101] For example, specifically 23 and Figure 26 As shown, the protrusion structure 81 can be provided only on the upper end face of the heat-conducting component 8, or only on the lower end face; specifically as follows... Figure 24 and Figure 27 As shown, the protrusion structure 81 can also be provided on both the upper and lower end faces of the heat-conducting component 8. The specific location of the protrusion structure 81 can be determined according to the actual path requirements of the hot flue gas or fresh cold air. For example, if the hot flue gas passes through the lower end face, the protrusion structure 81 can be provided on the lower end face of the heat-conducting component 8 or the lower end face of the heat-insulating and flow-guiding refractor 7. Figures 31 to 33 As shown, the arrangement of the protrusion structure 81 of the protective component 3 and the arrangement of the heat insulation and flow guiding refraction component 7 can be referred to the arrangement of the heat conducting component 8, and will not be described again here.

[0102] Preferably, the surfaces of the heat-conducting element 8 and / or the protective element 3 and / or the heat-insulating and flow-guiding refraction element 7 are curved, and the curvature of the curved surface is adapted to the contour of the pointed-bottom cookware. Taking the heat-conducting element 8 as an example, refer to... Figures 25 to 26 and Figure 29 As shown, the curvature of the surface of the heat-conducting component 8 matches the contour of the pointed-bottom cookware.

[0103] Understandably, the raised dot structure 81, located on the surfaces of the heat-conducting component 8 and the heat-insulating and flow-guiding refractor 7, effectively expands their surface area, providing ample contact space for heat exchange. During flow, hot flue gas tends to move in close contact with the surfaces of the heat-conducting component 8 and the heat-insulating and flow-guiding refractor 7. When flowing through the raised dot structure 81 on the heat-conducting component 8 and the heat-insulating and flow-guiding refractor 7, its flow trajectory undergoes undulations, extending the overall flow path of the hot flue gas and further slowing its exhaust velocity. Under the combined effect of extending the flow path and slowing the exhaust velocity, the contact time between the hot flue gas and the bottom of the cookware and the heat-conducting component 8 is significantly increased, and the contact range is more comprehensive. This allows the cookware to capture the maximum amount of heat energy released by the burner 93 during combustion, effectively reducing heat loss and further improving the thermal efficiency of the gas stove. Furthermore, the raised dot structure 81 also enhances the structural strength of the heat-conducting component 8 and the heat-insulating and flow-guiding refractor 7.

[0104] The protrusion structure 81 is set on the surface of the protective component 3, which can expand the protection range of the protective component 3 and improve the protection function of the protective component 3.

[0105] The surface of the heat-conducting element 8 is curved, which can match the contour of the pointed-bottom cookware, increasing the contact area between the heat-conducting element 8 and the cookware, enhancing the stability of the pointed-bottom cookware, and enabling the heat absorbed by the heat-conducting element 8 to be effectively conducted to the cookware, thus achieving good thermal efficiency.

[0106] In an optional embodiment, the heat-insulating and flow-guiding refractor 7 includes one or more of the following: microcrystalline plate, microcrystalline wafer, ceramic plate, ceramic sheet, metal plate, metal sheet, high-temperature resistant glass plate, and high-temperature resistant glass sheet, or a hybrid structure formed by combining multiple plates and sheets.

[0107] For example, in some embodiments of this application, the heat-insulating and flow-guiding refraction element 7 can be one of a single metal plate, metal sheet, microcrystalline plate, microcrystalline wafer, ceramic plate, or ceramic sheet, or it can be a structure formed by combining any number of metal plates, metal sheets, microcrystalline plates, microcrystalline wafers, ceramic plates, ceramic sheets, high-temperature resistant glass plates, or high-temperature resistant glass sheets.

[0108] As another example, the heat insulation and flow guiding refractor 7 can be made of a single piece of microcrystalline plate, or it can be made of a composite structure of microcrystalline wafers, metal sheets and microcrystalline wafers. The microcrystalline plate has corrosion resistance, and the metal sheet has good toughness and ductility. The corrosion resistance of the microcrystalline wafers resists erosion, while the toughness and ductility of the metal sheet absorb energy and prevent breakage, thereby improving the physical properties of the heat insulation and flow guiding refractor 7 and providing stronger protection than a single material.

[0109] Of course, the above content is only an example of the structure of the heat insulation and flow guiding refraction element 7. The structure of the heat insulation and flow guiding refraction element 7 is not limited. It can be selected according to actual needs and should be covered within the protection scope of this application.

[0110] Preferred, such as Figures 13 to 16 As shown, the cookware support system also includes a reinforcing structural component 73, which is fitted onto the heat-insulating and flow-guiding refraction component 7.

[0111] Understandably, the reinforcing structural component 73 is fitted outside the heat-insulating and flow-guiding refractor 7 and at least partially wraps around the heat-insulating and flow-guiding refractor 7, thereby enhancing the structural strength and stability of the heat-insulating and flow-guiding refractor 7. This allows the heat-insulating and flow-guiding refractor 7 to maintain its predetermined shape and relative position when subjected to the impact of hot flue gas or fresh cold air or under high temperature changes, thus achieving a good and stable airflow guiding function.

[0112] like Figure 13 and Figure 14 As shown, the reinforcing structural member 73 has a plurality of air guiding and passing structural parts 74 and / or air passages (not clearly shown in the figure) on the side opposite to the heat insulation and air guiding refraction member 7. The plurality of air guiding and passing structural parts 74 and / or air passages are distributed along the circumference of the reinforcing structural member 73, and each air guiding and passing structural part 74 and / or air passage extends along the radial direction of the reinforcing structural member 73.

[0113] Understandably, the arrangement of the airflow guiding structure 74 and / or the air passage optimizes the flow field distribution, eliminates flow dead zones, and the cold air flow channel helps to evenly distribute the air into the combustion zone, improves the fresh cold air flow efficiency, maintains sufficient oxygen supply in the burner 93, and makes the combustion of the burner 93 more complete, thereby improving combustion efficiency.

[0114] The airflow guiding structure 74 and / or air passages are distributed circumferentially along the reinforcing member and extend radially to guide and redistribute airflow, providing a smooth transition path for the fluid. This orderly guides the gathered or stagnant fresh cold air to the air inlet of the burner 93, allowing the fresh cold air to uniformly fill the entire flow channel cold air circulation passage. The fresh cold air can flow smoothly inward from all sides along the radial line of the reinforcing structure 73.

[0115] In addition, the radially extending air-guiding structure 74 and / or air vents can effectively separate fresh cold air and guide it to pass smoothly, thereby reducing the vibration or impact of fresh cold air on the reinforcing structure 73 and the heat-insulating air-guiding and refraction component 7, and improving the safety of the cookware support system.

[0116] This application also provides a gas stove, such as Figures 17 to 21 As shown, a cookware support system with protective function, including any one of the aforementioned features.

[0117] The cookware support system with protective functions can effectively protect components such as the ignition needle 901 and / or the flameout protection sensor 902, improving the stability of these components and thus enhancing the functional stability of the gas stove.

[0118] In an optional embodiment, the gas stove also includes a cooktop panel 91, a bottom shell 92, and a burner 93; The cooktop panel 91 is connected to the bottom shell 92 to form an accommodating space. The burner 93 is mounted on the bottom shell 92 and located within the accommodating space. The cookware support system is connected to the cooktop panel 91. Preferably, the cooktop panel 91 is provided with a connecting fastener 94, which connects the cooktop panel 91 and the bottom shell 92. The connecting fastener 94 is arranged along the circumferential direction of the burner 93 and is connected to the burner 93 to surround or partially surround the burner 93. The cookware support system is connected to the connecting fastener 94 and / or the cooktop panel 91.

[0119] Understandably, the connecting fastener 94 is used to connect the cooktop panel 91 and the bottom shell 92 of the gas stove, so that the connecting fastener 94, the cooktop panel 91 and the bottom shell 92 are connected as a whole, which enhances the stability of the overall structure of the gas stove. At the same time, the lower end of the connecting piece 2 or the support piece 4 is connected to the connecting fastener 94, which facilitates the positioning and installation of the cookware support system and simplifies the assembly and alignment process.

[0120] The connecting fastener 94 can also increase the heat conduction area, improve the heat conduction and heat dissipation speed, and act as a radiator to accelerate the heat dissipation of the cooktop panel 91 into the air, reduce the temperature of the cooktop panel 91, and thus play a role in protecting the core electronic components in the bottom shell 92 to a certain extent.

[0121] In addition, the connection between the connecting fastener 94 and the lower end of the cookware support system can also play a certain role in limiting or assisting in fixing. The connecting fastener 94 protrudes from the surface of the cookware panel 91 of the gas stove. The protruding part has the function of blocking and increasing friction, which can prevent the cookware support system from radially shifting or circumferentially rotating, thereby enhancing the connection stability between the cookware support system and the cookware panel 91.

[0122] Optionally, the connecting fastener 94 can be detachably installed separately from the cooktop panel 91, or the connecting fastener 94 can be integrally formed with the cooktop panel 91.

[0123] Optionally, for metal cooktop panels 91, the connecting fastener 94 and cooktop panel 91 can be designed as a single piece. The plasticity and structural stability of metal are well-suited to the single-piece molding process, further strengthening the connection and meeting the requirements of metal panels for both aesthetics and structural strength. The single-piece design eliminates the need for additional connectors such as screws and screw holes, further enhancing the overall structural stability of the gas cooktop. It also reduces wear and loosening at the connection point between the connecting fastener 94 and cooktop panel 91 due to long-term stress and heat, effectively extending the lifespan of the gas cooktop. Furthermore, the single-piece structure optimizes the appearance of the cooktop panel 91, avoiding the cluttered look caused by exposed connectors, resulting in a cleaner and more uniform panel surface and enhancing the product's visual appeal.

[0124] Optionally, the connecting fastener 94 and the cooktop panel 91 can also be designed as separate, detachable units. This separate, detachable design not only facilitates disassembly and replacement of parts during routine maintenance, reducing maintenance costs, but also allows for flexible replacement of the connecting fastener 94 according to actual usage needs, to match different usage scenarios, cookware types, or to meet the installation requirements and size compatibility of thermal efficiency enhancement devices. Furthermore, the separate structure reduces manufacturing complexity, making the production of individual components easier to control, and also facilitating product transportation and storage.

[0125] For example, the separate detachable connection between the connecting fastener 94 and the cooktop panel 91 can be achieved by means of connection such as snap-fit ​​connection, screw connection, riveting or fitting. The integral molding between the connecting fastener 94 and the cooktop panel 91 can be achieved by various processes, such as die casting or casting, stamping, stretching and bending.

[0126] Of course, the above content is only some examples of the connection method or manufacturing process between the connecting fastener 94 and the stove panel 91. There are no restrictions on the specific connection method or manufacturing process between the connecting fastener 94 and the stove panel 91. The connection method or manufacturing process between the connecting fastener 94 and the stove panel 91 can be selected according to actual needs. For example, the connecting fastener 94 can be placed directly or stacked on the stove panel 91, which is also a type of split and detachable connection. All of these should be covered within the protection scope of this application.

[0127] When using a glass cooktop panel 91, the connecting fastener 94 is applied to the cooktop panel 91, providing a certain degree of protection. More specifically, in some embodiments of this application, the cooktop panel 91 can be made of various materials, such as high-temperature resistant glass or metal. When the cooktop panel 91 is made of high-temperature resistant glass, the connecting fastener 94 is provided on the cooktop panel 91. The connecting fastener 94 covers the cooktop panel 91, protecting it and preventing it from cracking due to high temperatures. When the cooktop panel 91 is made of metal, the connecting fastener 94 does not need to be provided separately. The connecting fastener 94 can be formed with the metal panel in one piece, without a separate connecting fastener 94.

[0128] Understandably, on the one hand, the connecting fastener 94 can enhance structural strength and disperse stress. When it covers the cooktop panel 91, it can transform the localized concentrated stress on the cooktop panel 91 into a uniformly distributed load, significantly reducing the risk of deformation and breakage of the cooktop panel 91. On the other hand, the connecting fastener 94 also has good thermal conductivity, which helps the glass cooktop panel 91 dissipate heat and reduces the probability of the glass cooktop panel 91 cracking due to thermal shock caused by a sudden increase in local temperature. Furthermore, the connecting fastener 94 can shield the soup overflowing from the pot, effectively preventing the soup from splashing directly onto the cooktop panel 91, making it easier to keep the panel clean.

[0129] The connecting fastener 94 surrounds the burner 93 circumferentially, with one end connected to the cooktop panel 91 and the other end connected to the bottom shell 92. It serves to bear the stress between the cooktop panel 91 and the bottom shell 92, enhancing the overall structural strength of the gas stove. The connecting fastener 94 surrounds the burner 93, with the burner 93 located at the center of the connecting fastener 94. The cookware support system is connected to the connecting fastener 94 and / or the cooktop panel 91 via the connecting member 2, the support member 4, or the outer support member 6. This ensures that the cookware support system and the burner 93 are concentrically and coaxially arranged, contributing to uniform airflow distribution and thus improving the thermal efficiency of the gas stove.

[0130] Preferred, such as Figure 19 As shown, a protective element 95 is provided at the connection between the cooktop panel 91 and the connecting fastener 94. The protective element 95 is made of a material with elasticity and / or heat insulation effect to prevent heat energy from being directly transferred to the cooktop panel 91 through the connecting fastener 94.

[0131] For example, the material of the protective component 95 may be organic or inorganic and be able to withstand a certain high temperature.

[0132] Understandably, the connecting fastener 94 and the cooktop panel 91 are easily affected by the burner 93, resulting in thermal expansion and contraction. Furthermore, due to the different materials used, the connecting fastener 94 and the cooktop panel 91 have different coefficients of expansion, leading to inconsistent expansion amplitudes. The protective component 95, positioned between the cooktop panel 91 and the connecting fastener 94, can cope with the thermal expansion and contraction of the connecting fastener 94. Since the connecting fastener 94 and the cooktop panel 91 are easily affected by the burner 93, causing them to expand drastically, the protective component 95 provides a flexible compression and rebound space, absorbing the generated vibrations and acting as a buffer, thus maintaining the relative position of the connecting fastener 94 and the cooktop panel 91.

[0133] In addition, the protective component 95 can be implemented in the form of a heat insulation pad, which has a heat insulation effect and can block the conduction of heat between the connecting fastener 94 and the cooktop panel 91. This makes it difficult for the heat from the connecting fastener 94 to be transferred to the cooktop panel 91, reducing the direct heat source of the cooktop panel 91. To a certain extent, this prevents heat from accumulating on the cooktop panel 91, slows down the heating rate of the cooktop panel 91 during long-term use, and reduces the impact of the temperature rise of the cooktop panel 91 on the internal temperature of the bottom shell 92.

[0134] In some embodiments of this application, the protective element 95 may include mica sheet, ceramic fiber paper / pad, silicone rubber or metal spring washer, etc.

[0135] Of course, the above content is only a structural example of the protective element 95. There are no restrictions on the structure of the protective element 95. It can be selected according to actual needs and should all be covered within the scope of protection of this application.

[0136] In an optional embodiment, such as Figure 18 and Figure 19 As shown, the heat insulation and airflow guiding refraction component 7 of the cookware support system is located on the upper outer edge of the burner 93, and forms a fresh cold air delivery gap 72 with the outer edge of the burner 93. The fresh cold air delivery gap 72 constitutes a fresh cold air circulation channel, which is used to replenish fresh cold air to the surface combustion layer of the porous heating element 931 of the burner 93.

[0137] Understandably, the heat-insulating and air-guiding deflector 7 is located on the upper outer edge of the burner 93, and the fresh cold air delivery spacing 72 is formed on the outer edge of the burner 93, making the fresh cold air delivery spacing 72 close to the burner 93. On the one hand, it can obtain timely and effective replenishment of fresh cold air when the burner 93 is burning, ensuring the continuity, stability and completeness of the combustion of the burner 93.

[0138] On the other hand, the outer edge of the burner 93 has a high temperature, which causes local high temperature of the components and causes deformation of the components. The fresh cold air entering from the fresh cold air delivery gap 72 can exchange heat with this area, which can play a certain cooling effect and reduce the risk of damage to components such as the glass cooktop panel 91, thereby extending the service life of the gas stove.

[0139] On the other hand, since the incoming fresh cold air exchanges heat with the cooktop panel 91, it preheats the fresh cold air and increases its temperature. After entering the burner 93 and mixing with the gas, the initial temperature of the fresh cold air is also increased, thereby improving the combustion conditions, making the combustion more complete and the exhaust emissions lower, which further improves the thermal efficiency of the gas stove. Moreover, there is no need to set up a separate preheating device to heat the fresh cold air. Instead, the heat of the gas stove itself is used to improve the effective utilization rate of the gas stove's thermal energy.

[0140] In addition, the fresh cold air delivery spacing 72 is close to the burner 93, so that fresh cold air can be continuously and quickly supplied to the surface area of ​​the burner 93. This allows the burner 93 to respond more quickly and accurately when adjusting the firepower, thereby improving the response speed of the gas stove and improving the firepower adjustment performance of the gas stove.

[0141] Preferably, the connecting fastener 94 has an air passage hole 941. Fresh cold air flows sequentially through the lower end face of the heat-insulating guide and deflector 7, the air passage hole 941, and the bottom shell 92 to form a flow path. The flow path is used to supplement fresh cold air (oxygen) to the air inlet of the injector tube 932 of the burner 93. Alternatively, the connecting fastener 94 has a first inner ring opening (not explicitly shown in the figure) that matches the shape of the burner 93. The first inner ring opening is used to form an air passage gap 942 between the connecting fastener 94 and the burner 93 after the connecting fastener 94 is sleeved on the periphery of the cavity of the burner 93. Fresh cold air flows sequentially through the lower end face of the heat-insulating guide and deflector 7, the air passage gap 942, and the bottom shell 92 to form an airflow path. The airflow path is used to promote the internal and external circulation of air and to supplement fresh cold air to the air inlet of the injector tube 932 of the burner 93, providing sufficient oxygen for combustion. Understandably, an air passage hole 941 is provided in the connecting fastener 94 and / or an air passage gap 942 is formed between the connecting fastener 94 and the burner 93 to form an airflow path for replenishing fresh cold air to the air inlet of the ejector tube 932 of the burner 93. This can replenish fresh cold air to both the surface of the porous heating element 931 of the burner 93 and the air inlet of the ejector tube 932 of the burner 93, achieving dual air replenishment of the burner 93 and effectively improving the fresh cold air replenishment rate.

[0142] Understandably, an air passage 941 is provided in the connecting fastener 94 and / or an air passage gap 942 is formed between the connecting fastener 94 and the burner 93. Through one or a combination of these two structures, an airflow path is formed for supplying fresh cold air to the air inlet of the injector tube 932 of the burner 93. This airflow path can supply fresh cold air not only to the surface of the porous heating element 931 of the burner 93, but also to the air inlet of the injector tube 932 of the burner 93, achieving dual air supply to the burner 93. This dual supply design effectively improves the fresh cold air supply rate, fully meeting the necessary air volume required for the combustion process.

[0143] Specifically, the above design, based on the existing fresh cold air flow channel that supplies fresh cold air to the porous heating element 931 and its surface of the burner 93, further divides into another airflow path that supplies fresh cold air to the air inlet of the ejector tube 932 of the burner 93, forming at least two fresh cold air supply channels in different directions. One channel is used to supply fresh cold air to the air inlet of the ejector tube 932, and the other channel is used to supply fresh cold air to the porous heating element 931 of the burner 93.

[0144] The fresh, cold air flowing towards the injector 932 undergoes an initial mixing with the combustion gas upon entry, satisfying the primary air supply required for combustion in the burner 93. The fresh, cold air flowing towards the surface of the porous heating element 931 then provides a secondary air supply for combustion, thus comprehensively meeting the air volume requirements of the combustion process. This dedicated cold air flow channel improves the speed and mixing efficiency of the combustion gas and air ejected by the injector 932, significantly increasing the amount of air supplied to the burner 93 during combustion, thereby effectively ensuring the stability and completeness of combustion.

[0145] More specifically, in some embodiments of this application, the connecting fastener 94 is sleeved on the outer periphery of the burner 93. The diameter of the first inner ring of the connecting fastener 94 is larger than the diameter of the burner 93, so that when the connecting fastener 94 is sleeved on the burner 93, an air passage gap 942 is directly formed between the wall of the first inner ring and the periphery of the burner 93. The side wall of the connecting fastener 94 may be provided with a plurality of air passage holes 941. The plurality of air passage holes 941 are arranged along the circumferential direction of the connecting fastener 94 to improve the passage of fresh cold air. When the connecting fastener 94 is provided with air passage holes 941, the diameter of the first inner ring of the connecting fastener 94 can be equal to the diameter of the burner 93, so as to achieve a tight fit between the connecting fastener 94 and the burner 93.

[0146] Of course, the above content is only an example of the setting of the air passage 941 and the air passage distance 942. There are no restrictions on the setting of the air passage 941 and the air passage distance 942. They can be selected according to actual needs and should all be covered within the protection scope of this application.

[0147] Preferably, the air gap 942 is not less than 1 mm.

[0148] For example, the width of the air gap 942 is in the range of 1-30 mm, and the width of the air gap 942 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm or 45 mm, etc.

[0149] Of course, the above content is only an example of the width of the air passage 942. There is no limitation on the specific width of the air passage 942. It can be selected according to actual needs and should be covered within the protection scope of this application.

[0150] Understandably, the air gap 942 is set within the range of 1-45 mm. This gap provides ample space for fresh, cold air to flow smoothly into the bottom shell 92 and be delivered to the air inlet of the ejector tube 932. Furthermore, by appropriately setting this gap, the airflow can be effectively controlled, ensuring that at least a portion of the fresh, cold air is directly guided to the periphery of the burner 93 and the surface of the porous heating element 931. By controlling the airflow along two different paths, the air supply ratio required for combustion can be further optimized, thereby achieving better combustion efficiency in the burner 93.

[0151] The cookware support system of this application adopts a cold and hot airflow separation and directional discharge technology. The cold and hot airflows are separated by the heat-insulating guide and deflector 7. The hot flue gas generated during combustion is guided by the upper end surface of the heat-insulating guide and deflector 7 to be discharged along the bottom of the cookware to the edge of the cookware, which suppresses the flow rate of the hot flue gas and allows more heat energy to be absorbed by the cookware. At the same time, the physical characteristics of the heat-insulating guide and deflector 7 material are used to convert the heat energy of the hot flue gas into infrared radiation energy to heat the cookware in various ways, thereby improving thermal efficiency. In addition, the lower end surface of the heat-insulating guide and deflector 7 guides fresh cold air to the surface of the burner 93 flame outlet and the inside of the cookware bottom shell 92, and effectively manages the heat of the hot flue gas and fresh cold air, supplementing the oxygen demand during combustion, achieving complete combustion, and greatly improving the thermal efficiency of the gas stove and reducing exhaust emissions. There are clear national regulations regarding thermal efficiency and carbon monoxide emissions. The current standard for Grade 1 thermal efficiency of built-in cooktops is 63%. After adopting this application, the thermal efficiency can be significantly improved to over 70% (complying with the national standard "Energy Efficiency Limits and Energy Efficiency Grades for Gas Cooktops" issued on February 28, 2025, and implemented on March 1, 2026, which requires built-in / tabletop cooktops to achieve Grade 1 thermal efficiency of 70%). The national standard for carbon monoxide emissions is ≤0.05%. In particular, by utilizing the cookware support system technology of this application, the carbon monoxide emissions of gas cooktops can be reduced to ≤0.004%, far below the national standard, achieving high efficiency, low emissions, and clean combustion.

[0152] Furthermore, the diameter or area of ​​the air passage 941 can be designed with reference to the width of the air passage spacing 942. For example, the diameter can be set to 1-45 mm, which will not be elaborated here.

[0153] In an optional embodiment, a heat insulation layer 96 and / or a heat insulation cover 97 are provided between the cooktop panel 91 and the bottom shell 92, and the heat insulation layer 96 and / or the heat insulation cover 97 are provided to extend circumferentially along the burner 93.

[0154] Understandably, the heat insulation layer 96 and / or heat insulation cover 97 extend from the inside of the through hole toward the circumferential or axial direction of the burner 93, filling the relative gap between the cooktop panel 91 and the bottom shell 92, thereby constructing a continuous heat insulation barrier to block the heat conduction path from the cooktop panel 91 to the bottom shell 92 and prevent heat from being conducted into the interior of the bottom shell 92.

[0155] The insulation layer 96 adopts a structure composed of one or more of ceramic fiber bodies, ceramic fiber bodies, glass fiber boards, and glass fiber sheets; The cooktop panel 91 is composed of one or more of the following materials: microcrystalline board, glass board, and metal board.

[0156] For example, in some embodiments of this application, the heat insulation layer 96 may be one of ceramic fiber body and / or glass fiber body and / or a whole piece of ceramic fiber board, ceramic fiber sheet, glass fiber board, or glass fiber sheet, or it may be a structure composed of any combination of ceramic fiber board, ceramic fiber sheet, glass fiber board, or glass fiber sheet.

[0157] Of course, the above content is only an example of the structure of the insulation layer 96. There are no restrictions on the structure of the insulation layer 96. It can be selected according to actual needs and should be covered within the protection scope of this application.

[0158] For example, in some embodiments of this application, the cooktop panel 91 may be one of a single piece of microcrystalline plate, microcrystalline wafer, glass plate, glass sheet, metal plate, or metal sheet, or it may be a structure composed of any combination of microcrystalline plate, microcrystalline wafer, glass plate, glass sheet, metal plate, or metal sheet.

[0159] As another example, the cooktop panel 91 can adopt a composite structure of microcrystalline plate, metal plate and microcrystalline plate, wherein the microcrystalline plate has corrosion resistance and the metal plate has good toughness and ductility. The corrosion resistance of the microcrystalline plate resists erosion, while the toughness and ductility of the metal plate absorb energy and prevent breakage, thereby improving the physical properties of the cooktop panel 91 and providing stronger protection than a single material.

[0160] Of course, the above content is only an example of the structure of the cooktop panel 91. The structure of the cooktop panel 91 is not limited and can be selected according to actual needs. All of them should be covered within the protection scope of this application.

[0161] The through hole is located on the cooktop panel 91 and corresponds to the position of the burner 93.

[0162] It should be noted that when the distance between the bottom of the cookware and the cooktop panel 91 is reduced, the bottom of the cookware can easily reflect heat onto the cooktop panel 91, causing the temperature of the cooktop panel 91 to rise. This heat can then be conducted through the cooktop panel 91 to the bottom shell 92, potentially affecting the normal operation of the electronic components inside the bottom shell 92. The heat insulation layer 96 and / or the heat insulation cover 97 can block the heat energy gained by the cooktop panel 91 during combustion from being conducted into the bottom shell 92. This adapts to the actual need for a reduced distance between the bottom of the cookware and the cooktop panel 91. When the distance between the cookware and the panel is reduced, it effectively prevents the cookware from slipping and tipping over, creating a safe and stable working environment for the electronic components and valve body. The heat insulation layer 96 and / or the heat insulation cover 97 can also trap some of the heat released from the burner 93 within the combustion chamber, forcing the hot flue gas to carry more heat upwards and act on the bottom of the cookware, directly reducing ineffective heat loss and further improving the thermal efficiency of the gas stove.

[0163] With the cooperation of the heat insulation layer 96 and / or the heat insulation cover 97, the distance between the bottom of the pot and the cooktop panel 91 can be reduced, avoiding the problem of damage to the components in the bottom shell 92 due to excessive temperature. This allows for a lower distance between the bottom of the pot and the cooktop panel 91, while also reflecting the extra heat energy that the cooktop panel 91 can gain after reducing the distance between the cooktop panel 91 and the pot back to the bottom of the pot. This achieves a low-distance, concealed flame, and easy-to-clean design, significantly improving the thermal efficiency of the gas stove. The stove also maintains good stability, safety, and aesthetics during use.

[0164] For example, the distance between the bottom of the pot and the cooktop panel 91 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm or 20mm, etc.

[0165] Of course, no restrictions are placed on the specific distance between the bottom of the pot and the cooktop panel 91.

[0166] More specifically, in combination Figure 18 and Figure 21 As shown, the heat insulation layer 96 fills the space between the cooktop panel 91 and the bottom shell 92, forming a structural support. This effectively enhances the connection stability between the cooktop panel 91 and the bottom shell 92, reducing the shaking of the cooktop panel 91 during use and thus improving the safety of the cooktop. The heat insulation layer 96, located between the cooktop panel 91 and the bottom shell 92, also functions as a heat barrier, preventing heat transfer between the cooktop panel 91 and the bottom shell 92 and preventing the temperature of the bottom shell 92 from easily rising, thereby creating a suitable operating environment for the internal components. The components inside the bottom shell 92 may include a gas solenoid valve, electronic components, and a control circuit board. Of course, the above are only some examples of components, and no restrictions are placed on the components installed inside the bottom shell 92.

[0167] Preferably, one side of the heat insulation layer 96 is close to or attached to the cooktop panel 91, and the heat insulation cover 97 is disposed on the outer layer of the heat insulation layer 96. The heat insulation cover 97 is mesh-shaped and / or shell-shaped. Understandably, the heat insulation layer 96 extends circumferentially along the through-hole, and the heat insulation cover 97 extends circumferentially along the through-hole synchronously with the heat insulation layer 96. The heat insulation layer 96 and / or the heat insulation cover 97 effectively block the radiant heat, convective heat from the burner 93, and heat conduction from the cooktop panel 91, creating a relatively low-temperature working environment inside the bottom shell 92, such as 40℃-60℃. This significantly extends the service life of internal components such as the gas solenoid valve, electronic components, and control circuit board, ensuring the safety and reliability of the gas stove during long-term operation. Furthermore, by blocking heat energy through the heat insulation layer 96 or the heat insulation cover 97, the ineffective outward diffusion of heat energy from the burner 93 is reduced, heat loss is decreased, and the thermal efficiency of the gas stove is significantly improved. In addition, the heat insulation layer 96 fills the gap between the cooktop panel 91 and the bottom shell 92, which can form a structural support, enhance the connection stability between the cooktop panel 91 and the bottom shell 92, reduce the shaking of the cooktop panel 91 when the cooktop is in use, and further improve the safety of the cooktop during use.

[0168] Optionally, the heat shield 97 can be mesh-like and / or shell-like. Specifically, it can be entirely mesh-like, entirely shell-like, or a combination of partially mesh-like and partially shell-like.

[0169] Understandably, considering that the insulation layer 96 is usually made of soft materials, such as ceramic fiber or glass fiber, it is prone to collapse, deformation, and detachment under long-term gravity or thermal stress, resulting in local gaps that affect the insulation effect. The heat insulation cover 97 can connect the insulation layer 96 and the cooktop panel 91, supporting or wrapping the insulation layer 96 from below, providing comprehensive support, enhancing the deformation resistance of the insulation layer 96, helping the insulation layer 96 resist the effects of gravity or thermal stress, maintaining a good condition, and extending the retention time of the insulation performance.

[0170] Specifically, in some embodiments of this application, the heat insulation layer 96 can be made of ceramic fiber or glass fiber material, which has the characteristics of high temperature resistance, low thermal conductivity, and light and soft texture. The heat insulation cover 97 can be made of metal material to enhance structural strength and heat reflection capability.

[0171] Of course, the above are just examples of materials for the insulation layer 96 and the insulation cover 97, and there are no restrictions on the specific materials to be used.

[0172] The heat insulation layer 96 can be set on the cooktop panel 91 in two ways: one is that the heat insulation layer 96 is set close to the cooktop panel 91, that is, there is a certain gap between the heat insulation layer 96 and the cooktop panel 91; the other is that the heat insulation layer 96 is attached to the cooktop panel 91, that is, there is no gap between the heat insulation layer 96 and the cooktop panel 91, and they are in close contact.

[0173] For example, the heat insulation layer 96 can be positioned close to the cooktop panel 91 in a variety of ways. For instance, the heat insulation layer 96 can be glued to the cooktop panel 91 with adhesive, or heat insulation cotton can be attached between the cooktop panel 91 and the heat insulation layer 96 to form a gap between the two.

[0174] For example, the heat insulation layer 96 can be made to adhere to the cooktop panel 91 by making the heat insulation layer 96 directly contact the cooktop panel 91.

[0175] Preferably, one side of the heat insulation layer 96 is close to the cooktop panel 91, so that there is a certain gap between the cooktop panel 91 and the heat insulation layer 96.

[0176] Preferably, a heat insulation layer 96 is provided between any two of the connecting fastener 94, the cooktop panel 91, the bottom shell 92, the burner 93, and the heat insulation cover 97.

[0177] Understandably, a heat insulation layer 96 may be provided between the cooktop panel 91 and the bottom shell 92, between the cooktop panel 91 and the periphery of the burner 93, between the cooktop panel 91 and the heat insulation cover 97, between the bottom shell 92 and the periphery of the burner 93, and between the periphery of the burner 93 and the heat insulation cover 97.

[0178] By setting up a heat insulation layer 96 in all directions, the heat-insulating device, including the heat insulation layer 96 and / or the heat insulation cover 97, enhances the heat energy barrier between the cooktop panel 91 and the bottom shell 92. This design can effectively solve the problem of increased heat energy absorption by the cooktop panel 91 caused by the reduced distance between the bottom of the pot and the cooktop panel 91. At the same time, it helps to maintain the stability of the internal temperature of the bottom shell 92, thereby greatly improving the safety of the gas stove during use.

[0179] Preferably, the heat insulation cover 97 and / or the heat insulation layer 96 are at least partially located below the cooktop panel 91 and the connecting fastener 94 to prevent the heat energy of the cooktop panel 91 from diffusing into the interior of the bottom shell 92, thereby reducing the temperature of the bottom shell 92. Understandably, the heat insulation cover 97 and the heat insulation layer 96 are located at least partially below the cooktop panel 91 and the connecting fastener 94, which can effectively block the conduction of heat from the cooktop panel 91 to the bottom shell 92, so that the temperature inside the bottom shell 92 remains stable.

[0180] Optionally, the heat shield 97 can be a shell with a partially perforated structure or a closed shell; Preferably, the heat insulation cover 97 is a closed shell with a certain heat insulation space inside, which blocks the transfer of heat energy. The closed shell is a one-layer, multi-layer, or multi-segment spliced ​​structure. Preferably, the heat insulation layer 96 is a single layer, multiple layers, or an integrally formed structure; more preferably, the heat insulation layer 96 covers part or all of the cooktop panel 91.

[0181] Understandably, the insulation layer 96 can be a single-layer structure or a multi-layer structure. In a multi-layer structure, the materials of different layers can be the same or different.

[0182] The heat insulation layer 96 can cover the entire area of ​​the cooktop panel 91. However, to reduce costs, it can cover only a portion of the cooktop panel 91, only needing to fulfill the function of blocking heat.

[0183] The heat shield 97 is a closed shell, and a certain heat insulation space is formed inside the closed shell, which blocks the transfer of heat energy. A closed shell can be a single-layer or multi-layer structure. In a multi-layer structure, the materials of different layers can be the same or different.

[0184] When the heat insulation cover 97 is a closed shell, a heat-insulating space is formed inside to block the transfer of heat energy. The heat-insulating space can be filled with air to form an air interlayer to achieve heat insulation; the heat-insulating space can also be vacuumed to form a vacuum layer to block the conduction of heat.

[0185] Preferably, the insulation space is vacuum-treated. The vacuum-treated insulation space has good insulation performance, and the vacuum layer formed can achieve a strong insulation effect with a relatively thin thickness, which helps to realize the compact design of the gas stove.

[0186] Preferably, the heat shield 97 is provided with structural members that connect to the bottom shell 92 and / or the burner 93; Understandably, the structural components are designed to connect the heat insulation cover 97 with the bottom shell 92 and / or the burner 93, which helps to achieve precise positioning of the heat insulation cover 97 with the bottom shell 92 and / or the burner 93, making it less likely for the heat insulation cover 97, the burner 93 and the cookware to shift, thus achieving a more stable thermal efficiency.

[0187] For example, structural components may be brackets, clips, or screws. Of course, there are no limitations on the structural components used to connect the heat shield 97 to the base shell 92 and / or the burner 93.

[0188] Preferably, the heat insulation cover 97 and / or the heat insulation layer 96 have a second inner ring opening that matches the shape of the burner 93. The second inner ring opening is used to fit around the cavity of the burner 93 and extends from the cavity of the burner 93 to part or all of the cooktop panel 91.

[0189] Understandably, the second inner ring opening matches the shape of the burner 93, forming a relatively continuous and complete circumferential thermal barrier. This, to a certain extent, prevents heat from the burner 93 from diffusing outwards in the radial direction, slowing heat conduction to the sidewalls of the bottom shell 92, thereby preventing users from being burned and effectively improving the safety performance of the stove during use.

[0190] Meanwhile, with the blocking effect of the heat insulation cover 97 and / or the heat insulation layer 96, the heat generated by the burner 93 is forced to be transferred upwards and concentrated on the bottom of the pot for heating, thereby reducing the waste of heat energy caused by irregular heat loss and improving the thermal efficiency of the gas stove.

[0191] Furthermore, the heat insulation cover 97 and / or the heat insulation layer 96 extend from the periphery of the burner 93 cavity to a portion or all of the cooktop panel 91, specifically extending to the edge of the cooktop panel 91. Through the connection between the heat insulation cover 97 and / or the heat insulation layer 96 and the cooktop panel 91, the structural strength of the cooktop panel 91 is significantly enhanced, thereby protecting the cooktop panel 91, especially reducing the risk of the glass cooktop panel 91 cracking due to high temperatures, and minimizing safety hazards.

[0192] This application provides a cookware support system and gas stove with protective functions, which can protect key components such as ignition needle 901 and / or flameout protection sensor 902, providing a more stable working environment, reducing the influence of external factors, and improving the stability and reliability of the gas stove's functions.
