Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas stove technology, and in particular to a gas stove rack. Background Technology
[0002] Gas stoves are one of the main cooking appliances in modern kitchens. The burner rack is an important component of the gas stove, responsible for supporting and fixing the stove, bearing the high temperature of the burner surface and the weight of the cookware. The energy-concentrating ring is usually arranged in a ring around the combustion area of the burner rack. It can guide the air to flow orderly to the combustion area, ensuring complete combustion of gas, improving combustion efficiency, and also preventing heat from spreading to the surroundings, so that the heat is more concentrated on the cooking appliances, thus improving the performance of the gas stove.
[0003] The number and structure of the heat-concentrating rings affect the amount of air entering the burner and the heat loss. A single-layer heat-concentrating ring has limited effect on heat accumulation, and the burner frame is usually an integral structure with the base, making it difficult to adapt to different types of cooktops. Utility Model Content
[0004] Therefore, it is necessary to provide a gas stove rack that can improve heat concentration and offers greater installation flexibility to address the above issues.
[0005] A gas stove frame, comprising:
[0006] Base;
[0007] Multiple furnace legs are evenly distributed along the circumference of the base, and the base is detachably connected to the furnace legs to support the furnace legs;
[0008] A first energy-concentrating ring and a second energy-concentrating ring are placed on the plurality of furnace feet, the first energy-concentrating ring being located above the second energy-concentrating ring, a gap being present between the first energy-concentrating ring and the second energy-concentrating ring, and the diameter of the second energy-concentrating ring being larger than the diameter of the first energy-concentrating ring.
[0009] The aforementioned gas stove burner frame, with its double-layered energy-concentrating rings, enhances the gas stove's thermal efficiency. When the gas stove is ignited, the flame is blocked and guided by the energy-concentrating rings as it rises, causing the flame to contract and converge. The gap between the first and second energy-concentrating rings forms a flow channel, allowing the flame to follow the direction of this gap, changing its original tendency to spread outwards and concentrating at the bottom of the cookware, resulting in more even and rapid heating. Multiple burner feet are evenly distributed along the circumference of the first and second energy-concentrating rings and are fixedly connected to them, enabling the burner frame to evenly distribute the weight of the cookware onto each burner foot, providing stable support. The base and burner feet are detachable, improving the convenience of daily cleaning and maintenance. If a burner foot or base is damaged during long-term use, only the damaged individual part needs to be replaced, without replacing the entire unit. The energy-concentrating rings can be separated from the base, allowing them to adapt to different bases or stoves. This means a single set of energy-concentrating rings and burner feet can be used on bases and stoves of different specifications, improving its versatility and ease of maintenance. The above-mentioned gas stove racks can improve combustion efficiency and offer high installation flexibility.
[0010] In one embodiment, the base is provided with a protrusion, and the side of the furnace foot is provided with a snap-fit part, the protrusion engaging with the snap-fit part.
[0011] In one embodiment, the snap-fit portion consists of a blind hole and a stop plate, the stop plate being disposed on the side wall of the blind hole;
[0012] The protrusion includes a first protrusion and a second protrusion. The first protrusion extends vertically from the upper surface of the base, and the second protrusion is located on one side of the top of the first protrusion and extends radially along the base. The second protrusion is placed in the snap-fit space between the stop plate and the blind hole so that the protrusion snaps into the snap-fit part.
[0013] In one embodiment, the thickness of the second protrusion is the same as the distance between the stop plate and the bottom wall of the blind hole;
[0014] The height of the second protrusion is not greater than the distance between the stop plate and the side wall opposite to the stop plate in the blind hole.
[0015] In one embodiment, the first energy-concentrating ring has a second slot for inserting the furnace foot.
[0016] In one embodiment, a third slot is provided on the furnace foot for inserting the second energy-concentrating ring.
[0017] In one embodiment, a limiting block is provided on the furnace foot, the upper surface of the limiting block abuts against the lower surface of the first energy-concentrating ring, and when the first energy-concentrating ring is inserted into the furnace foot, the lower surface of the limiting block abuts against the upper surface of the second energy-concentrating ring, the limiting block is located above the second energy-concentrating ring, and the limiting block is used to form an air channel between the first energy-concentrating ring and the second energy-concentrating ring.
[0018] In one embodiment, the cross-sectional shape of the first energy-concentrating ring and the second energy-concentrating ring is arc-shaped.
[0019] In one embodiment, a water tray is further included, which is arranged around the base, and an annular boss is provided on the water tray, the outer diameter of which is less than or equal to the inner diameter of the base.
[0020] In one embodiment, a first limiting part is provided on the inner sidewall of the base, and a second limiting part is provided on the outer side of the water tray. The first limiting part and the second limiting part cooperate to limit the relative rotation of the base and the water tray. Attached Figure Description

[0035] Figure 1 This is a schematic diagram of the structure of a gas stove frame provided in an embodiment of the present invention; Figure 2 An exploded view of a gas stove frame provided in an embodiment of this utility model; Figure 3 This is a schematic diagram of the air passage formed by the burner frame of a gas stove according to an embodiment of the present invention; see reference. Figures 1 to 3 This application provides a gas stove rack, comprising:
[0036] Base 400;
[0037] Multiple furnace feet 300 are evenly distributed around the circumference of the base 400, and the base 400 is detachably connected to the furnace feet 300 to support the furnace feet 300.
[0038] A first energy-concentrating ring 100 and a second energy-concentrating ring 200 are placed on the plurality of furnace feet 300. The first energy-concentrating ring 100 is located above the second energy-concentrating ring 200. There is a gap between the first energy-concentrating ring 100 and the second energy-concentrating ring 200, and the diameter of the second energy-concentrating ring 200 is larger than the diameter of the first energy-concentrating ring 100.
[0039] The burner rack refers to the part of the gas stove used to support cooking utensils such as pots and pans. The energy-concentrating ring is a ring-shaped device installed on the gas stove. When the gas stove is in use, the energy-concentrating ring surrounds the flame, keeping it close to the bottom of the pot, reducing heat loss, improving heat utilization, and allowing the pot to absorb heat faster, thus increasing cooking speed. The energy-concentrating ring can be made of materials such as cast iron or stainless steel, allowing it to withstand prolonged high-temperature cooking environments. The specifications of the first energy-concentrating ring 100 and the second energy-concentrating ring 200 can be determined according to the specifications of the matching stove. Since the diameter of the second energy-concentrating ring 200 is larger than that of the first energy-concentrating ring 100 and it is located below it, there is a gap between the two. After the gas stove is ignited, the flame is initially blocked and guided by the first energy-concentrating ring 100 as it rises. The first energy-concentrating ring 100 causes the flame to initially contract and converge, preventing it from spreading excessively in all directions. Because the second energy-concentrating ring 200 has a larger diameter, the flame is further converged and guided at the gap between the two rings. This gap acts as a conduit, causing the flame to deviate from its original tendency to spread outwards and concentrate more at the bottom of the cookware. Simultaneously, the first energy-concentrating ring 100 reflects and guides some of the heat that would otherwise spread diagonally upwards and outwards downwards, while the second energy-concentrating ring 200 further concentrates this heat near the bottom of the cookware. This reduces heat loss, improves heat utilization, and saves gas and cooking time. Multiple burner legs 300 are evenly distributed circumferentially along the first energy-concentrating ring 100 and the second energy-concentrating ring 200, and are fixedly connected to them. This allows the burner rack to evenly distribute the weight of the cookware onto each burner leg 300 when supporting the cookware, providing stable support. The base 400 is detachably connected to the burner legs 300, allowing the burner rack to be disassembled into modular components, reducing the overall size and space occupation. Different materials, sizes, or shapes of burner legs 300 or base 400 can be easily replaced according to actual needs, such as the load-bearing requirements of the burner rack and the usage environment. Different designs of the base 400 can also be used, facilitating standardized production of the base 400 and burner legs 300. Different models or styles of burner racks can be adapted to different gas stoves and usage needs by simply replacing some parts, improving production efficiency and reducing production costs. The detachable connection between the burner legs 300 and base 400 can be achieved using threaded connections, snap-fit connections, slot connections, or magnetic connections. The inner surface of the stove feet 300 may have a beveled structure, which can more stably support the cookware and is less likely to block the flame jet from the burner holes.
[0040] The aforementioned gas stove burner frame, by incorporating double-layer energy-concentrating rings, enhances the gas stove's thermal efficiency. When the gas stove is ignited, the flame is obstructed and guided by the energy-concentrating rings as it rises, causing the flame to contract and converge. The gap between the first energy-concentrating ring 100 and the second energy-concentrating ring 200 forms a guiding channel, causing the flame to follow the direction of this gap, changing its original tendency to spread outwards and concentrating at the bottom of the cookware, resulting in more even and rapid heating. Multiple burner feet 300 are evenly distributed circumferentially along the first energy-concentrating ring 100 and the second energy-concentrating ring 200 and are fixedly connected to them, ensuring the burner frame provides support... When supporting the cookware, the weight of the cookware is evenly distributed across the burner legs 300, providing stable support. The base 400 is detachably connected to the burner legs 300, improving the convenience of daily cleaning and maintenance. If the burner legs 300 or base 400 are damaged during long-term use, only the damaged individual parts need to be replaced, without replacing the entire unit. The energy-concentrating ring can be separated from the base 400, allowing it to be adapted to different bases 400 or cooktops. This means a set of energy-concentrating rings and burner legs 300 can be used on different sizes of bases 400 and cooktops, improving its versatility and ease of maintenance. The above-mentioned gas stove burner frame improves combustion efficiency and offers high installation flexibility.
[0041] Figure 4 A schematic diagram of the structure of the stove foot 300 of the gas stove frame provided in an embodiment of the present utility model; Figure 5 This is a schematic diagram of the structure of the base 400 of a gas stove rack according to an embodiment of the present invention. (See attached diagram.) Figures 4 to 5 In one exemplary embodiment, a protrusion 410 is provided on the base 400, and a snap-fit portion 310 is provided on the side of the furnace foot 300. The protrusion 410 and the snap-fit portion 310 are engaged. As shown in the figure, the protrusion 410 can protrude upward from the upper surface of the base 400, and the snap-fit portion 310 can be located on the side or bottom surface of the furnace foot 300. The engagement of the two can limit the relative vertical displacement and relative horizontal rotation between the furnace foot 300 and the energy-concentrating ring and the base 400, making the furnace frame structure more stable.
[0042] In an exemplary embodiment, the engaging portion 310 comprises a blind hole and a stop plate 320, the stop plate 320 being disposed on the sidewall of the blind hole. The protrusion 410 includes a first protrusion 411 and a second protrusion 412. The first protrusion 411 extends vertically from the upper surface of the base 400, and the second protrusion 412 is located on one side of the top of the first protrusion 411 and extends radially along the base 400. The second protrusion 412 is placed in the engaging space between the stop plate 320 and the blind hole, so that the protrusion 410 engages with the engaging portion 310. Figures 4 to 5As shown, the blind hole of the snap-fit part 310 can be square or rectangular in shape and is opened on the side wall of the furnace foot. The depth direction of the blind hole is perpendicular to the side wall of the furnace foot. The stop plate 320 is provided on the side wall of the blind hole and is used to limit the protrusion when the protrusion 410 is engaged with the snap-fit part 310, so as to prevent the furnace foot 300 and the base 400 from separating. When installing the furnace foot 300 and the base 400, the furnace foot 300 and the energy-concentrating ring can be rotated so that the second protrusion 214 enters the blind hole of the snap-fit part 310 from the larger opening area below the stop plate 320. After the second protrusion 214 enters the blind hole, the furnace foot 300 and the energy-concentrating ring are moved down so that the second protrusion 214 moves to the upper part of the blind hole, thereby being restricted in its horizontal displacement by the stop plate 320. This limiting method can achieve the limiting of the furnace foot 300 and the base 400 by relying on gravity. When it is necessary to disassemble the furnace foot 300 and the base 400, lift the furnace foot 300 and the energy-concentrating ring so that the protrusion 410 moves to the lower part of the blind hole 310 and can be released from the limiting of the stop plate 320. At this time, rotating the furnace foot 300 and the energy-concentrating ring can separate them from the base 400, which can realize the convenient installation and disassembly of the furnace foot 300 and the base 400.
[0043] In an exemplary embodiment, the thickness of the second protrusion 412 is the same as the distance between the stop plate 320 and the bottom wall of the blind hole; the height of the second protrusion 412 is not greater than the distance between the stop plate 320 and the side wall of the blind hole opposite to the stop plate 320. The thickness and height of the second protrusion 412 refer to its horizontal and vertical dimensions when the base 400 is placed on a horizontal surface, respectively. When the thickness of the second protrusion 412 is the same as the distance between the stop plate 320 and the bottom wall of the blind hole, the horizontal displacement of the second protrusion can be better restricted, reducing the relative rotation between the furnace foot 300 and the energy-concentrating ring and the base 400, and improving the stability of the fit between the base 400 and the furnace foot 300. Its height being no greater than the distance between the stop plate 320 and the side wall of the blind hole opposite to the stop plate 320 allows the second protrusion 412 to smoothly enter the blind hole, making the installation process smoother and improving assembly efficiency.
[0044] In an exemplary embodiment, the first energy-concentrating ring 100 is provided with a second slot 110 for inserting the furnace foot 300. The width and depth of the second slot 110 are adapted to the shape of the furnace foot 300.
[0045] In an exemplary embodiment, a third slot is provided on the furnace foot 300 for inserting the second energy-concentrating ring 200. The shape of the third slot matches the contour shape of the second energy-concentrating ring 200. When the cross-sectional shape of the second energy-concentrating ring 200 is arc-shaped, the shape of the third slot can also be arc-shaped.
[0046] In an exemplary embodiment, a limiting block 330 is provided on the burner foot 300. The upper surface of the limiting block 330 abuts against the lower surface of the first energy-concentrating ring 100. When the first energy-concentrating ring 100 is inserted into the burner foot 300, the limiting block 330 is positioned above the second energy-concentrating ring 200. The limiting block 330 is used to form a first air passage 600 between the first energy-concentrating ring 100 and the second energy-concentrating ring 200. The formation of the first air passage 600 between the first energy-concentrating ring 100 and the second energy-concentrating ring 200, and the formation of a second air passage 700 between the second energy-concentrating ring 200 and the gas stove, can improve the thermal efficiency of the gas stove. In some embodiments, the lower surface of the limiting block 330 abuts against the upper surface of the second energy-concentrating ring 200, which allows for more even force distribution on the limiting block 330 and provides more stable support for the first energy-concentrating ring 100.
[0047] In an exemplary embodiment, the cross-sectional shape of the first energy-concentrating ring 100 and the second energy-concentrating ring 200 is arc-shaped. Here, "arc-shaped cross-section" means that the longitudinal cross-section of the first energy-concentrating ring 100 and the second energy-concentrating ring 200 is arc-shaped, and both the inner and outer surfaces of the energy-concentrating rings are curved, with the diameter gradually decreasing from top to bottom, thereby enabling them to concentrate and guide the flame.
[0048] In one exemplary embodiment, a water tray 500 is further included, which is disposed around the base 400. The water tray 500 has an annular boss 510, the outer diameter of which is smaller than the inner diameter of the base 400. For example... Figure 4 As shown, an annular boss 510 is formed on the inner side of the water pan 500. The outer diameter of the annular boss 510 is less than or equal to the inner diameter of the base 400, so that the furnace frame can be initially positioned by being surrounded by the inner wall of the base 400 through the annular boss 510 during installation.
[0049] In an exemplary embodiment, a first limiting part 420 is provided on the inner sidewall of the base 400, and a second limiting part 511 is provided on the outer side surface of the water tray 500. The first limiting part 420 and the second limiting part 511 cooperate to limit the relative rotation of the base 400 and the water tray 500. Figure 4As shown, the first limiting part 420 can be a groove provided on the inner sidewall of the base 400, and the second limiting part 511 can be a protrusion provided on the outer sidewall of the annular boss 510 of the water tray 500. When the water tray 500 and the base 400 are installed and engaged, the protrusion can be located in the groove, thereby limiting the relative rotation between the base 400 and the water tray 500 and improving the stability of the installation. In other embodiments, the first limiting part 420 can be a protrusion provided on the inner sidewall of the base 400, and the second limiting part 511 can be a groove provided on the outer sidewall of the annular boss 510 of the water tray 500. The protrusion and groove can be semi-circular or other structures, and the edges can be chamfered, thereby reducing the local stress concentration phenomenon between the water tray 500 and the base 400.
[0050] In one exemplary embodiment, a fully open double-layer stove rack with a detachable base is provided to improve the thermal efficiency of the gas stove, speed up cooking, and facilitate installation on different water trays. This structure consists of a circular detachable base, four slotted stove feet, an inner energy-concentrating ring, an outer energy-concentrating ring, and a water tray. The inner and outer energy-concentrating rings are welded to the slotted stove feet. The stove feet and base are modified by a rectangular protrusion engaging with a semi-enclosed slot. The rectangular protrusion first engages with the square slot to enter the semi-enclosed slot, and then the stove foot, under gravity, allows the rectangular protrusion to engage with the semi-enclosed slot. The stove foot can be completely fixed to the circular base under its own weight. To disassemble, the stove foot is lifted upwards and rotated to separate the slot from the protrusion, forming a detachable base structure.
[0051] The working method of the above-mentioned fully open double-layer furnace frame with detachable base is as follows: the inner and outer energy-concentrating rings are first welded and fixed to the slot furnace foot, and then the rectangular block protrusion of the circular detachable base is inserted into the square groove of the slot furnace foot. The weight of the slot furnace foot plus the energy-concentrating ring can make the rectangular block protrusion of the circular detachable base completely embedded in the semi-closed slot of the slot furnace foot, and finally installed on the circular water tray. When the integrated stove is connected to the gas pipeline, a primary mixed gas is generated through the control valve and nozzle. The mixed gas then flows out from the burner holes and comes into contact with the air on the burner frame under the action of the igniter, completing combustion. During the combustion of the primary mixed gas in the air, according to the law of heat balance, the heat absorbed by the pot is the effective heat, and the heat dissipated into the environment is the lost heat. The air passage between the pot bottom and the inner energy-concentrating ring, between the inner and outer energy-concentrating rings, and between the outer energy-concentrating ring and the cooktop is changed, reducing the volume of flue gas flowing into the environment. This allows the flue gas to wash over the pot bottom more quickly and accumulate more heat at the pot bottom. The two energy-concentrating rings can prevent excess air from entering the burner, preventing excess heat from being lost to the environment. The heat generated by the flue gas through thermal radiation and thermal convection can be accumulated on the inner and outer energy-concentrating rings. During combustion, the heat from the inner and outer energy-concentrating rings can be transferred to the pot bottom through thermal radiation, reducing heat loss.
[0052] The fully open double-layer furnace frame with a detachable base provided in the above embodiments has the following beneficial effects: the bottom of the furnace feet is connected to the circular base, providing a dual load-bearing function; the circular base and water pan have a tighter and more stable fit, preventing loosening; both the inner and outer energy-concentrating rings are arc-shaped, conforming to the trajectory of the flame jet from the burner holes; the double-layer energy-concentrating rings can control the air passage, ensuring complete combustion of air and fuel gas and improving combustion efficiency. The furnace feet can be detached from the circular base via slots, allowing the furnace feet and energy-concentrating rings to be installed on different types of water pans and bases.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
