Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and in particular to a stove energy-concentrating ring and a gas stove. Background Technology

[0002] Existing gas stoves generally have an energy-concentrating ring to improve the thermal efficiency of gas combustion. The energy-concentrating ring surrounds the burner and can reduce the heat lost to the air during gas combustion. However, the energy-concentrating ring surrounds the burner and prevents secondary air from entering the flame of the burner, resulting in insufficient secondary air supply. This leads to incomplete gas combustion, which easily produces harmful gases such as carbon monoxide during combustion. It also causes the flame to appear yellow and the amount of flue gas emissions to be high, thus reducing the thermal efficiency of the gas stove. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a stove energy-concentrating ring, which effectively improves the supply of secondary air and enhances the uniformity of the mixture of secondary air and gas.

This effectively improves the completeness of gas combustion, reduces the generation of harmful gases, and reduces flue gas emissions, which is beneficial to improving the thermal efficiency of the gas stove. Simultaneously, the protrusions on the inner plate act as turbulence, facilitating the thorough and uniform mixing of the secondary air with the gas after it enters, further improving the completeness of gas combustion.

[0009] In one embodiment, a partition is further provided in the air cavity and extends in the same direction as the inner disc body. The bottom of the partition is connected to the bottom plate. The partition divides the air cavity into a first air cavity near the secondary air hole and a second air cavity away from the secondary air hole. The air inlet is provided on the bottom plate at the bottom of the second air cavity. An air passage connecting the first air cavity and the second air cavity is provided on the upper part of the partition.

[0010] In one embodiment, the top of the partition is connected to the top plate, and the air passage includes a plurality of air holes disposed in the upper region of the partition, the plurality of air holes being arranged at intervals along the circumference of the partition.

[0011] In one embodiment, the boss includes arcuate protrusions, and a plurality of the arcuate protrusions are arranged at circumferential intervals along the inner disk.

[0012] In one embodiment, the boss includes strip-shaped protrusions, a plurality of strip-shaped protrusions are arranged at intervals along the circumference of the inner disk and extend along the height direction of the inner disk, and each strip-shaped protrusion is provided with a plurality of secondary air holes at intervals along the length direction.

[0013] In one embodiment, the plurality of strip-shaped protrusions are inclined in the same direction from bottom to top toward the inner wall of the inner disc.

[0014] In one embodiment, the outer surface of the strip-shaped protrusion is an arc surface, and the curvature of the arc surface is the same as the curvature of the inner disc.

[0015] In one embodiment, the boss is formed by stamping, and the side of the boss facing the inner wall of the inner disc has an arc transition area. The opening of the arc transition area gradually widens from the top of the boss to the air cavity.

[0035] The following is combined Figures 1 to 11 The following describes embodiments of the present invention.

[0036] According to an embodiment of the present invention, a stove energy-concentrating ring is provided, comprising an inner plate 1, an outer plate 2 sleeved outside the inner plate 1, a top plate 3 connecting the top of the inner plate 1 and the outer plate 2, and a bottom plate 4 connecting the bottom of the inner plate 1 and the outer plate 2, wherein an air cavity 6 is provided between the inner plate 1 and the outer plate 2; the inner wall of the inner plate 1 is provided with a plurality of protrusions 11 protruding toward the axial direction of the inner plate 1, and the protrusions 11 are provided with secondary air holes 111 penetrating the inner plate 1; at least one of the bottom plate 4 and the outer plate 2 is provided with a plurality of air inlets 41, and the secondary air holes 111 and the air inlets 41 are all connected to the air cavity 6.

[0037] Taking a gas stove with an energy-concentrating ring as an example, the energy-concentrating ring is installed outside the burner of the gas stove. The ring has a secondary air hole 111 on its inner plate 1 and an air inlet 41 on at least one of its outer plate 2 and bottom plate 4. Air from outside the energy-concentrating ring enters the air chamber 6 through the air inlet 41 and then flows into the flame of the burner through the secondary air hole 111, thus replenishing the secondary air. This effectively improves the completeness of gas combustion, reduces the generation of harmful gases, and reduces flue gas emissions, thereby improving the thermal efficiency of the gas stove. Simultaneously, a boss 11 is provided on the inner plate 1. The boss 11 acts as a turbulence device, facilitating the thorough and even mixing of the secondary air with the gas after it enters, further improving the completeness of gas combustion.

[0038] In some alternative embodiments, such as Figures 4 to 7 , Figure 10 and Figure 11 As shown, the air inlet 41 is located on the base plate 4, and multiple air inlets 41 are arranged at intervals along the circumference of the base plate 4. With the air inlet 41 located on the base plate 4, secondary air enters the air cavity 6 from the bottom of the stove's energy-concentrating ring, and then enters the interior of the inner plate 1 from the air cavity 6 through the secondary air hole 111. Compared to placing the air inlet 41 on the outer plate 2, this increases the airflow path, thereby reducing heat loss and helping to ensure the energy-concentrating effect of the stove's energy-concentrating ring.

[0039] In some embodiments, such as Figure 5 As shown, multiple air inlets 41 are arranged at equal intervals along the circumference of the base plate 4, which facilitates the uniform entry of air into the energy-concentrating ring.

[0040] Optionally, in some embodiments, the air inlet 41 is a strip-shaped hole, with the long side of the air inlet 41 extending radially along the base plate 4. This arrangement can increase the opening area of ​​the air inlet 41 and ensure the amount of air intake.

[0041] like Figure 6 and Figure 7As shown, in some embodiments, the stove's energy-concentrating ring also includes a partition 5 disposed within the air cavity 6 and extending in the same direction as the inner plate 1. The bottom of the partition 5 is connected to the bottom plate 4. The partition 5 divides the air cavity 6 into a first air cavity 61 near the secondary air hole 111 and a second air cavity 62 away from the secondary air hole 111. An air inlet 41 is disposed on the bottom plate 4 at the bottom of the second air cavity 62. The upper part of the partition 5 is provided with an air passage 51 connecting the first air cavity 61 and the second air cavity 62. Due to the obstruction of the partition 5, the air entering from the air inlet 41 first flows to the second air cavity 62 above the air inlet 41, and then flows from the air passage 51 at the top of the partition 5 to the first air cavity 61 between the partition 5 and the inner plate 1. The air then enters the interior of the inner plate 1 from the secondary air hole 111. This arrangement effectively increases the airflow path and can further reduce the heat loss inside the energy-concentrating ring.

[0042] like Figure 7 As shown, in some embodiments, the top of the partition 5 is connected to the top plate 3, and the air duct 51 includes a plurality of air holes in the upper region of the partition 5. The plurality of air holes are arranged at intervals along the circumference of the partition 5. The bottom of the partition 5 is connected to the bottom plate 4, and the top of the partition 5 is connected to the top plate 3. This can improve the strength and stability of the stove's energy-concentrating ring structure. The air duct 51 is located in the upper region of the partition 5 and is located away from the air inlet 41 on the bottom plate 4, which can increase the airflow path and reduce energy loss.

[0043] In some optional embodiments, the air holes are strip-shaped holes that extend along the height direction of the disk surface of the partition 5. Multiple air holes are arranged at equal intervals along the circumference of the partition 5, which is conducive to the uniform entry of air into the interior of the inner disk 1.

[0044] In other embodiments, the top of the partition 5 is spaced a certain distance from the inner wall of the top plate 3, thus forming a ring of air passages 51 between the top of the partition 5 and the inner wall of the top plate 3.

[0045] In some embodiments, the base plate 4 is a plane. In this case, the distance between the bottom of the inner plate 1 and the bottom of the outer plate 2 is large, and the radial width of the base plate 4 is large. This can increase the opening area of ​​the air inlet 41, which is beneficial to ensure the air intake at the bottom of the energy-concentrating ring.

[0046] In other embodiments, the base plate 4 is a downwardly convex arc surface. In this case, the distance between the bottom of the inner plate 1 and the bottom of the outer plate 2 is relatively small, and the two ends of the arc-shaped base plate 4 connect the bottom of the inner plate 1 and the bottom of the outer plate 2.

[0047] In some embodiments, the inner plate 1, outer plate 2, partition 5, top plate 3, and bottom plate 4 are integrally formed. In some embodiments, the top plate 3 is a horizontally extending plane.

[0048] In some embodiments, such as Figures 1 to 7 As shown, the boss 11 includes arc-shaped protrusions. Multiple arc-shaped protrusions are arranged at intervals along the circumference of the inner disc 1. The arc-shaped protrusions have a small area, which makes them easy to form on the inner disc 1. At the same time, the multiple arc-shaped protrusions are arranged at intervals along the circumference of the inner disc 1, which can ensure the uniformity of air intake. In addition, the multiple arc-shaped protrusions are conducive to improving the turbulence effect, which can improve the uniformity of secondary air and fuel mixture, thereby promoting the complete combustion of fuel.

[0049] like Figure 1 and Figure 3 As shown, in some embodiments, the arc-shaped protrusions are arranged in two rows, one above the other. Multiple arc-shaped protrusions in each row are arranged at equal intervals along the circumference of the inner disc 1. The arc-shaped protrusions arranged vertically can be aligned or staggered circumferentially. When the upper and lower arc-shaped protrusions are aligned, the air inlet 41 on the bottom plate 4 can be aligned with or staggered circumferentially with the aligned arc-shaped protrusions.

[0050] In other embodiments, the arc-shaped protrusions may be arranged in one or more rows. When three rows of arc-shaped protrusions are arranged, the upper and lower rows of arc-shaped protrusions are staggered along the circumference of the inner disk 1, which is more conducive to the uniform entry of air into the interior of the inner disk 1. Preferably, the arc-shaped protrusions are arranged in two or three rows at intervals along the height direction of the inner disk 1.

[0051] like Figure 8 and Figure 9 As shown, in some embodiments, the boss 11 includes strip-shaped protrusions. Multiple strip-shaped protrusions are arranged at intervals along the circumference of the inner disk 1 and extend along the height direction of the inner disk 1. Each strip-shaped protrusion is provided with multiple secondary air holes 111 at intervals along its length. The arrangement of multiple strip-shaped protrusions at intervals along the circumference of the inner disk 1 and extending along the height direction of the inner disk 1 facilitates the uniform entry of secondary air into the interior of the inner disk 1. The boss 11 includes strip-shaped protrusions, and multiple secondary air holes 111 can be provided on a single strip-shaped protrusion. Furthermore, the relatively large area of ​​the strip-shaped protrusions reduces the number of bosses 11, simplifying the manufacturing process of the bosses 11.

[0052] In some embodiments, a plurality of strip-shaped protrusions are arranged at equal intervals along the circumference of the inner disk 1, and a plurality of secondary air holes 111 are arranged at equal intervals along the length of the strip-shaped protrusions. This arrangement can further improve the uniformity of secondary air entering the inner disk 1.

[0053] In some embodiments, such as Figure 8 and Figure 9 As shown, the inner disc 1 between adjacent strip-shaped protrusions is provided with secondary air holes 111, which can increase the number of secondary air holes 111, thereby increasing the amount of secondary air entering the inner disc 1, which is conducive to more complete combustion of gas.

[0054] like Figure 9 As shown, in some embodiments, multiple strip-shaped protrusions are inclined in the same direction from bottom to top toward the inner wall of the inner disc 1. The multiple strip-shaped protrusions form a structure similar to the shape of fan blades, which can effectively accelerate the flow of secondary air entering the inner side of the inner disc 1, which is beneficial to improving the mixing effect of secondary air and gas, and can improve the uniformity and completeness of gas combustion.

[0055] In some embodiments, the angle of inclination of the strip-shaped protrusion relative to the height direction of the inner disc 1 does not exceed 45°, which helps to ensure the effect of accelerating the airflow.

[0056] like Figure 9 As shown, in some embodiments, the outer surface of the strip-shaped protrusion is an arc surface, and the curvature of the arc surface is the same as that of the inner plate 1. This helps to maintain the coordination between the strip-shaped protrusion and the overall structure of the inner plate 1, and helps the strip-shaped protrusion reflect the heat radiated outward by the burner back to the bottom of the pot.

[0057] In some embodiments, the bottom of the strip-shaped protrusion is spaced a certain distance from the bottom of the inner disc 1, and the top of the strip-shaped protrusion is spaced a certain distance from the top of the inner disc 1.

[0058] In some embodiments, the boss 11 is formed by stamping. The side of the boss 11 facing the inner wall of the inner disc 1 is provided with an arc transition area 112. From the top of the boss 11 to the air cavity 6, the opening of the arc transition area 112 gradually expands, which facilitates air from the air cavity 6 into the secondary air hole 111, facilitates the forming of the boss 11, and helps to ensure the overall strength of the inner disc 1 after stamping.

[0059] In this embodiment, both the arc-shaped protrusion and the strip-shaped protrusion have an arc-shaped transition area 112 on the side facing the inner wall of the inner disc 1.

[0060] According to an embodiment of the present invention, another aspect is provided: a gas stove, including a stove platform and a stove energy-concentrating ring disposed on the stove platform.

[0061] This gas stove features a secondary air hole 111 on the inner plate 1 of its energy-concentrating ring. An air cavity 6 is formed between the inner plate 1 and the outer plate 2. An air inlet 41 is provided on at least one of the outer plate 2 and the base plate 4. Air from outside the energy-concentrating ring enters the air cavity 6 through the air inlet 41 and then flows into the flame of the burner through the secondary air hole 111, thus replenishing the secondary air. This effectively improves the completeness of gas combustion, reduces the generation of harmful gases, and reduces flue gas emissions, thereby improving the thermal efficiency of the gas stove. Furthermore, a boss 11 is provided on the inner plate 1. The boss 11 acts as a turbulence breaker, facilitating the thorough and even mixing of the secondary air with the gas after it enters, further improving the completeness of gas combustion.

[0062] like Figure 1 and Figure 8 As shown, in some embodiments, the gas stove also includes a pot corner bracket, which is placed on the stovetop. The top wall of the pot corner bracket is located above the top plate 3. The pot corner bracket is used to support the pot, which can ensure the safety and stability of cooking.

[0063] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0064] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this 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.
