Abstract
Description
Technical Field
[0001] This application relates to the field of gas stove technology, and in particular to a gas stove pot rack assembly and a gas stove. Background Technology
[0002] Gas stoves are a type of cooking equipment widely used in kitchens. They generate flames by burning natural gas, liquefied petroleum gas, or other fuels to directly heat cookware and complete the cooking process.
[0003] Gas stoves have a pot rack above the burners to support cooking utensils. Gas is emitted from the burners and mixes with air for combustion, with the flame directly heating the bottom of the pot. However, when pots are placed on the rack, the bottom of the pot obstructs the smooth flow of surrounding air, resulting in incomplete mixing of gas and air. Some gas fails to burn completely without sufficient oxygen, reducing thermal efficiency and producing harmful gases such as carbon monoxide.
[0004] Therefore, how to improve the combustion efficiency of gas stoves and reduce harmful gas emissions has become a technical problem that needs to be solved. Utility Model Content
[0005] This application provides a gas stove pot rack assembly and a gas stove, which can improve the combustion efficiency of the gas stove and reduce harmful gas emissions.
[0006] In a first aspect, embodiments of this application provide a gas stove pot rack assembly, including a pot rack comprising:
[0007] The energy-concentrating plate has a clearance opening to avoid the burner; the energy-concentrating plate has a cookware support surface and a bottom surface in the thickness direction, the cookware support surface is a concave first arc surface, and the clearance opening is located in the arc bottom area of the first arc surface; the energy-concentrating plate has multiple sides in the circumferential direction, and the intersection of two adjacent sides forms a corner, the corner extends away from the center of the energy-concentrating plate, and the height of any side at the corner is higher than its own height in the area between two adjacent corners;
[0008] Cookware support feet are located on the cookware support surface to support the cookware.
[0009] The gas stove pot support assembly provided in this application provides a heat-collecting cavity by setting the pot support surface of the energy-concentrating plate as a concave first arc surface. When the flame is ejected from the relief opening and impacts the bottom of the pot, the high-temperature flue gas can flow back to the bottom of the pot under the guidance of the first arc surface, thereby refocusing the scattered heat on the central area of the bottom of the pot. This prolongs the contact time between the flue gas and the pot, reduces the radiation of heat between the energy-concentrating plate and the pot to the surroundings, and suppresses heat loss caused by excessively fast high-temperature flue gas flow, reducing convective heat loss and thus improving heat exchange efficiency. This is beneficial for improving the combustion efficiency of the gas stove and reducing the emission of harmful gases.
[0010] Meanwhile, by concentrating heat in the center of the cookware's bottom, the temperature around the heat-concentrating plate remains relatively low. This ensures that when operating the gas stove, the user's hands are kept away from the hot area at the bottom of the cookware, avoiding the risk of burns and enhancing the safety of the gas stove.
[0011] In addition, the corner section can laterally reflect the high-temperature flue gas that diffuses to the corner, thereby redirecting the high-temperature flue gas back to the bottom area of the cookware, further extending the residence time of the high-temperature flue gas at the bottom of the cookware, thus further increasing the combustion efficiency and reducing the emission of harmful gases.
[0012] In some embodiments, the shape of the first arc surface matches the shape of the bottom of the wok in the cookware.
[0013] In some embodiments, the height difference between the corner and the clearance is greater than or equal to 3cm and less than or equal to 4cm.
[0014] In some embodiments, the bottom surface is a convex second arc surface, the shape of which matches the shape of the cookware support surface.
[0015] In some embodiments, the lengths of all sides of the energy-concentrating disk are equal, and the length of one side of the energy-concentrating disk is... The diameter of the bottom of the flat-topped pan tested in the cookware category is... , and Satisfying the condition:
[0016] .
[0017] In some embodiments, the number of pot racks is at least two, and the pot racks are arranged sequentially along a first direction, with adjacent pot racks connected to each other.
[0018] In some embodiments, the number of cookware support legs is multiple, and the multiple cookware support legs are spaced apart at the circumferential edge of the energy-concentrating plate.
[0019] In some embodiments, the energy-concentrating plate is provided with a cookware support foot in the middle area of each side;
[0020] The energy-concentrating plates in two adjacent pot racks are joined together on their closest sides, and the pot support legs on both sides are connected to each other.
[0021] Secondly, embodiments of this application also provide a gas stove, comprising:
[0022] panel;
[0023] The burner is mounted on the panel;
[0024] As in any of the above embodiments, the gas stove pot rack assembly is mounted on top of the burner, and the clearance opening in the gas stove pot rack assembly is used to avoid the burner.
[0025] The gas stove provided in this application embodiment includes the aforementioned gas stove pot rack assembly, and therefore has the beneficial effects of a gas stove pot rack assembly. High-temperature flue gas can flow back to the bottom of the pot under the guidance of the first arc surface, so as to refocus the scattered heat on the central area of the bottom of the pot. This prolongs the contact time between the flue gas and the pot, while also reducing the radiation of heat between the energy-concentrating plate and the pot to the surroundings, and suppressing the heat loss caused by the excessively fast flow rate of high-temperature flue gas, reducing convective heat loss, thereby improving the combustion efficiency of the gas stove and reducing the emission of harmful gases.
[0026] In some embodiments, the number of burners is at least two, and the burners are sequentially mounted on the panel along a first direction;
[0027] The gas stove pot rack assembly includes at least two pot racks with clearance openings, and each burner has a corresponding pot rack mounted on its top. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0045] Figure 1 This is a schematic diagram of the structure of a gas stove provided in an embodiment of this application.
[0046] Please refer to Figure 1 The gas stove 100 is a widely used cooking device in the kitchen. It generates a flame by burning natural gas, liquefied petroleum gas, or other gas to directly heat the pot and cookware to complete the cooking process.
[0047] In related technologies, gas stoves have a pot rack above the burner to support cooking utensils. Gas is emitted from the burner and mixes with air for combustion, with the flame directly heating the bottom of the pot. However, when the pot is placed on the rack, the bottom of the pot obstructs the smooth flow of surrounding air, resulting in insufficient mixing of gas and air. Some gas fails to burn completely without sufficient oxygen, reducing thermal efficiency and producing harmful gases such as carbon monoxide.
[0048] In view of this, this application provides a gas stove pot rack assembly and a gas stove. The gas stove pot rack assembly includes a pot rack 10, which includes an energy-concentrating plate 1 and multiple pot support legs 2. The energy-concentrating plate 1 has a pot support surface and a bottom surface in the thickness direction. The pot support surface is a concave first arc surface, which allows a heat-collecting cavity to be formed between the bottom of the pot and the pot support surface. When the flame is ejected from the relief opening and impacts the bottom of the pot, the high-temperature flue gas can flow back to the bottom of the pot under the guidance of the first arc surface, thereby refocusing the scattered heat on the central area of the bottom of the pot. Meanwhile, the intersection of two adjacent sides of the energy-concentrating plate forms a corner. The height of any side at the corner is higher than its own height in the area between the two adjacent corners, causing the corner to be raised. This allows for lateral reflection of the high-temperature flue gas that diffuses to the corner, thereby redirecting the high-temperature flue gas back to the bottom area of the cookware. This prolongs the contact time between the flue gas and the cookware, reduces the radiation of heat between the energy-concentrating plate 1 and the cookware to the surroundings, and inhibits heat loss caused by excessively fast high-temperature flue gas flow. This reduces convective heat loss and improves heat exchange efficiency, which is beneficial for improving the combustion efficiency of the gas stove 100 and reducing the emission of harmful gases.
[0049] The following description, in conjunction with the accompanying drawings, describes the gas stove pot rack assembly and gas stove provided in the embodiments of this application.
[0050] Figure 2 This is an exploded schematic diagram of the gas stove 100 provided in an embodiment of this application. Figure 3 This is a structural schematic diagram of the gas stove 100 provided in an embodiment of this application from another perspective.
[0051] Please refer to Figures 1 to 3 This application provides a gas stove pot rack assembly, including a pot rack 10, which includes an energy-concentrating plate 1 and a plurality of pot support legs 2.
[0052] Figure 4 for Figure 1 A schematic diagram of the structure of the medium-sized cookware 10. Figure 5 for Figure 1 A schematic diagram of the structure of the medium-sized cookware 10 from another perspective.
[0053] Please refer to Figure 2 and 4Specifically, the energy-concentrating plate 1 has a clearance opening 111 to avoid the burner 30, so that the flame generated by the burner 30 can directly act on the bottom of the pot through the clearance opening 111.
[0054] Please refer to Figure 3 , Figure 4 and Figure 5 In this embodiment, the energy-concentrating plate 1 has a cookware support surface and a bottom surface in the thickness direction y. A cookware support foot 2 is disposed on the cookware support surface to support the cookware. Thus, when the cookware is placed on the cookware support foot 2, a heat-collecting cavity can be formed between the bottom of the cookware and the energy-concentrating plate 1. By placing the cookware support foot 2 on the cookware support surface, a certain distance can be maintained between the bottom of the cookware and the cookware support surface, ensuring that the flame has sufficient space for complete combustion.
[0055] Specifically, the cookware support surface is a concave first arc surface 112, and the clearance opening 111 is located at the bottom of the arc surface 112. When the flame is ejected upwards through the clearance opening 111, it spreads outwards after contacting the bottom of the cookware. The first arc surface 112 guides the spreading flame and high-temperature flue gas, causing them to reflect along the first arc surface 112 and refocus on the central area of the cookware bottom, thereby reducing heat radiation to the surrounding areas. This prolongs the contact time between the high-temperature flue gas and the bottom of the cookware, while also suppressing heat loss caused by excessively high flue gas flow rate, reducing convection losses, and increasing heat exchange efficiency and heat utilization. Furthermore, flue gas recirculation promotes secondary combustion of incompletely burned gases, making combustion more complete. Thus, under the same heat load, cooking time can be shortened, the combustion efficiency of the gas stove 100 can be improved, and gas consumption and emissions of incomplete combustion products can be reduced.
[0056] It is understandable that the first arc surface 112 can block the flow of external air, thereby reducing the interference of ambient airflow on the combustion zone, maintaining the stability of flame combustion, and reducing heat loss caused by air disturbance.
[0057] Meanwhile, because heat is concentrated at the bottom of the cookware, the temperature of the surrounding area of the energy-concentrating plate 1 is relatively low. This means that when the user operates the panel 20 of the gas stove 100, the area of their hand contact is away from the high-temperature area at the bottom of the cookware, thus avoiding the risk of burns during operation and enhancing the safety of using the gas stove.
[0058] Please refer to Figure 4 and Figure 5In this embodiment, the energy-concentrating disk 1 has a corner portion 114 at the intersection of two adjacent sides. The corner portion 114 extends toward the side away from the center of the energy-concentrating disk 1. The height of either side at the corner portion 114 is higher than its own height in the area between two adjacent corner portions 114, so that the corner portion 114 can be tilted upward in the direction away from the energy-concentrating disk 1.
[0059] Specifically, since the clearance opening 111 is located at the bottom of the first arc surface 112, the flame is located in the central area of the energy-concentrating plate 1, at which point the flame and high-temperature flue gas diffuse outwards. The raised corner 114 of the energy-concentrating plate 1 can laterally reflect the high-temperature flue gas that diffuses to the corner 114, thereby redirecting the high-temperature flue gas back to the bottom area of the cookware, further extending the residence time of the high-temperature flue gas at the bottom of the cookware, and thus further increasing the combustion efficiency and reducing the emission of harmful gases.
[0060] At the same time, the raised corner 114 can also form a physical barrier to suppress air convection, reduce the interference of external air flow on flame stability, weaken the influence of ambient wind speed on the combustion process, ensure the complete combustion of gas, and reduce the generation of harmful gases such as carbon monoxide.
[0061] Please refer to Figure 4 and Figure 5 By setting the raised corner 114, the high-temperature flue gas can be returned without setting an additional flange or protrusion structure on the outer periphery of the energy-concentrating disk 1, thus avoiding the accumulation of exhaust gas at the outer periphery of the energy-concentrating disk 1 and enabling the combustion products to be discharged in time.
[0062] Meanwhile, as the flue gas flows along the surface of the energy-concentrating plate 1 towards the corner 114, the change in flow direction creates a local low-pressure zone at the corner 114, resulting in rotational motion and the formation of vortices. These vortices allow some of the high-temperature flue gas to remain at the corner 114, thus prolonging the residence time of heat in the edge area of the cookware, thereby increasing the temperature of the bottom of the pot by raising the temperature of the edge area.
[0063] Please refer to Figure 4 and Figure 5 In some embodiments, the energy-concentrating plate 1 includes a square plate 11, which forms a cookware support surface and a bottom surface on two sides in the thickness direction y, and forms a corner portion 114 at the intersection of two adjacent sides in the circumferential direction.
[0064] Specifically, compared to a round pan, a square pan 11 can form a stronger linear reflection at the midpoints of its four sides, but the reflection effect is weaker in the four corner areas. This results in a "cross-shaped concentration" of heat distribution on the bottom of the pan, meaning that the temperature is higher in the areas corresponding to the midpoints of the sides, while the temperature is lower in the areas corresponding to the four corners. This allows users to place their hands in the cooler corner areas when handling the cookware, reducing the risk of burns and improving the user experience.
[0065] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the shape of the first arc surface 112 matches the shape of the bottom of the wok in the cookware. Thus, when the wok is placed on the cookware support legs 2, a highly uniform gap is formed between the outer surface of the wok bottom and the first arc surface 112, allowing the high-temperature flue gas to be distributed more smoothly and evenly and fill the entire gap. This prolongs the contact time between the high-temperature flue gas and the bottom of the wok, resulting in more complete combustion and further reducing the generation of harmful gases such as carbon monoxide.
[0066] Please refer to Figure 1 , Figure 4 and Figure 5 Furthermore, by matching the shape of the first arc surface 112 with the shape of the bottom of the wok in the cookware, the flame and high-temperature smoke can be reflected regularly at the gap, concentrating the heat more in the central area of the bottom of the wok, thereby further improving the heat utilization rate and the combustion efficiency of the gas stove 100.
[0067] It is understood that the shape of the first arc surface 112 matches the shape of the bottom of the wok in the cookware. The shape of the first arc surface 112 can be the same as or similar to the shape of the bottom of the wok, for example, the same or close to the radius of curvature. This embodiment does not impose any restrictions on this.
[0068] Please refer to Figure 4 and Figure 5 In some embodiments, the height difference between the corner portion 114 and the clearance opening 111 is greater than or equal to 3cm and less than or equal to 4cm.
[0069] Specifically, when the height difference between the corner 114 and the clearance opening 111 is less than 3cm, such as 1cm, 1.5cm, or 2cm, the raised height of the corner 114 is insufficient, resulting in an excessive distance between the corner 114 and the bottom of the pot. This causes the high-temperature fumes to diffuse excessively before reaching the reflective surface. Simultaneously, the low raised height of the corner 114 results in poor guiding effect on the high-temperature fumes, failing to create an effective reflection angle and thus leading to poor accumulation of the high-temperature fumes.
[0070] When the height difference between the corner 114 and the clearance opening 111 is greater than 4cm, the excessive height of the corner 114 can easily increase the flow resistance of the high-temperature flue gas, thus affecting the stability of combustion. Simultaneously, the corner 114 can obstruct the timely discharge of exhaust gas, leading to insufficient oxygen supply, incomplete combustion, and the production of more harmful gases such as carbon monoxide.
[0071] Therefore, in this embodiment, by controlling the height difference between the corner portion 114 and the clearance opening 111 within the range of 3cm to 4cm, such as 3cm, 3.5cm or 4cm, it can be ensured that the corner portion 114 forms a sufficient reflection angle while maintaining an appropriate reflection distance. This ensures effective flue gas recirculation and avoids heat loss due to excessive space, thereby improving combustion efficiency and reducing the generation of harmful gases such as carbon monoxide.
[0072] Please refer to Figure 4 and Figure 5 In some embodiments, the bottom surface is a convex second arc surface 113, and the shape of the second arc surface 113 matches the shape of the cookware support surface.
[0073] Specifically, the curvature of the second arc surface 113 is matched with that of the first arc surface 112 so that the wall thickness of the energy-concentrating disk 1 can be kept basically consistent. In this way, when the energy-concentrating disk 1 is heated, the heat can be evenly conducted to the entire energy-concentrating disk 1, avoiding local thermal stress concentration and improving the reliability of the energy-concentrating disk 1.
[0074] Meanwhile, the convex second arc surface 113 can also increase the contact area with the flame, thereby improving the heat absorption efficiency and further enhancing the combustion efficiency.
[0075] Please refer to Figure 4 and Figure 5 In some embodiments, the lengths of all sides of the energy-concentrating plate 1 are equal, the length of one side of the energy-concentrating plate 1 is L, and the diameter of the bottom of the test flat-topped pot in the cookware is D. L and D satisfy Formula 1.
[0076] (Formula 1)
[0077] Specifically, the equal length of each side of the energy-concentrating disk 1 allows heat to diffuse evenly from the center of the disk to the surrounding area, avoiding local stress concentration caused by structural asymmetry and ensuring the reliability of the energy-concentrating disk 1 in high-temperature environments.
[0078] Please refer to Figure 4 and Figure 5The side length L of the energy-concentrating plate 1 is matched with the bottom diameter of the flat-topped pot and kept between 1.2D and 1.5D to ensure that the energy-concentrating plate 1 can effectively cover the bottom of the pot, so that the vortex can be retained at the bottom of the pot, prolonging the residence time of high-temperature flue gas, increasing the bottom temperature of the pot, and preventing high-temperature flue gas from escaping from the edge, thus ensuring both thermal efficiency and safety in use.
[0079] Specifically, when the side length L of the energy-concentrating plate 1 is less than 1.2D, the size of the energy-concentrating plate 1 is small, and the bottom edge area of the cookware cannot be effectively covered. The heat of the cookware is easily lost in large quantities through radiation and air convection. At the same time, the area between the first arc surface 112 and the bottom of the cookware is small, and high-temperature flue gas will escape from the edge of the energy-concentrating plate 1, failing to form an effective return path, resulting in low thermal efficiency.
[0080] When the side length L of the energy-concentrating plate 1 is greater than 1.5D, the size of the energy-concentrating plate 1 is too large. The area of the energy-concentrating plate 1 that extends beyond the projection range of the cookware will continuously absorb combustion heat and cannot be effectively transferred to the cookware, resulting in energy waste. At the same time, an excessively large energy-concentrating plate 1 will also obstruct normal air circulation, leading to incomplete combustion and the generation of harmful gases such as carbon monoxide.
[0081] Figure 6 This is a schematic diagram of the combination of two cookware 10 provided in an embodiment of this application.
[0082] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the number of pot racks 10 is at least two, and the pot racks 10 are arranged sequentially along the first direction x, with adjacent pot racks 10 connected to each other.
[0083] Specifically, by connecting multiple pot racks 10, the support range of the pot racks 10 is expanded, providing a stable support base for pots of different sizes, while also ensuring the overall stability of the pot racks 10 and preventing individual pot racks 10 from shifting or tipping over during use.
[0084] The multiple pot racks 10 can be the same or different in size, and each pot rack 10 corresponds to a burner 30 of a gas stove 100 to meet different cooking scenarios.
[0085] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, there are multiple cookware support feet 2, which are spaced apart on the circumferential edge of the energy-concentrating plate 1 to ensure the stability of the cookware support feet 2 in supporting the energy-concentrating plate 1 and the cookware.
[0086] In this embodiment, the cookware support feet 2 are located on the cookware support surface so that the bottom of the cookware and the cookware support surface can maintain a certain distance, ensuring that the flame has enough space to burn fully.
[0087] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the energy-concentrating plate 1 is provided with a cookware support leg 2 in the middle area of each side. The energy-concentrating plates 1 in two adjacent cookware racks 10 are joined together on the two sides that are close to each other, and the cookware support legs 2 on the two sides are connected to each other.
[0088] Among them, the central area of each side of the energy-concentrating disk 1 can be understood as the midpoint of each side and its surrounding area.
[0089] Specifically, when the two pot racks 10 are joined together along the first direction x, the edges of the adjacent energy-concentrating plates 1 form a continuous plane. The two pot support legs 2 located at the joining edges can be fixedly connected by a connecting structure, thereby increasing the support area of the pot rack 10, reducing the force on a single support leg, and avoiding the problem of pot tilting caused by discontinuous support.
[0090] In this embodiment, no restrictions are placed on the connection method of two adjacent cookware support feet 2. The two adjacent cookware support feet 2 can be connected as one piece or as separate pieces, and the appropriate choice can be made according to actual needs.
[0091] For example, two adjacent cookware support legs 2 can be connected by snap-fit.
[0092] It should be noted that when two adjacent cookware support legs 2 are connected as a single piece, the two cookware racks 10 can be manufactured using a one-piece molding method.
[0093] Please refer to Figure 1 , Figure 2 and Figure 4 This application also provides a gas stove 100, including a panel 20, a burner 30, and a gas stove pot rack assembly as described in any of the above embodiments. The burner 30 is mounted on the panel 20, the gas stove pot rack assembly is mounted on top of the burner 30, and the clearance opening 111 in the gas stove pot rack assembly is used to avoid the burner 30.
[0094] Specifically, panel 20 serves as the support platform for gas stove 100, and burner 30 is fixedly mounted on panel 20. The gas inlet of burner 30 is connected to the gas supply system. A control knob is provided on panel 20, allowing the user to adjust the gas valve opening and air damper size. When gas and air are mixed in a specific ratio, they are ignited at the top of burner 30 by an ignition device to form a flame. A clearance opening 111 is positioned directly opposite the flame outlet of burner 30, ensuring that the flame can directly act on the bottom of the cookware through the clearance opening 111.
[0095] The gas stove 100 provided in this application embodiment includes the aforementioned gas stove pot rack assembly, and therefore has the beneficial effects of the gas stove pot rack assembly. High-temperature flue gas can flow back to the bottom of the pot under the guidance of the first arc surface 112, so as to refocus the scattered heat on the central area of the bottom of the pot. This prolongs the contact time between the flue gas and the pot, while also reducing the radiation of heat between the energy-concentrating plate 1 and the pot to the surroundings, and suppressing the heat loss caused by the excessively fast flow rate of high-temperature flue gas, reducing convective heat loss, thereby improving the heat exchange efficiency, which is conducive to improving the combustion efficiency of the gas stove 100 and reducing the emission of harmful gases.
[0096] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the number of burners 30 is at least two, and the burners 30 are sequentially mounted on the panel 20 along the first direction x. The gas stove pot rack assembly includes at least two pot racks 10, each pot rack 10 having a clearance opening 111, and each burner 30 has a corresponding pot rack 10 mounted on its top.
[0097] Specifically, by setting up multiple burners 30 and pot supports 10, the gas stove 100 can perform multiple cooking operations simultaneously. Each burner 30 can independently control the heat level and supports different cooking utensils with the corresponding pot support 10. For example, a user can stir-fry on one burner 30 while stewing or keeping warm on another burner 30.
[0098] For example, there are two burners 30 with different heat loads. The larger pot rack 10 is adapted to the high heat load burner 30, and the larger energy-concentrating plate 1 can form a more concentrated heat energy mass, which is suitable for cooking scenarios that require rapid heating, such as stir-frying. The smaller pot rack 10 is adapted to the low heat load burner 30, and the smaller energy-concentrating plate 1 can achieve precise heat control, which is suitable for cooking scenarios that require slow cooking, such as stewing.
