Description

Technical Field

[0001] The present invention relates to the technical field of kitchenware, in particular to a fire distributor and a burner. Background Art

[0002] The burner includes a flame divider and a fire cover, and the fire cover is arranged on the flame divider. The flame divider is provided with an air inlet, and the fire cover is provided with fire holes. Since the air inlet is arranged on one side of the flame divider seat, the fire holes on the fire cover are at different distances from the air inlet. The fire holes close to the air inlet will have an air outlet speed significantly faster than the air outlet speed of the fire holes far away from the air inlet due to the direct airflow. As a result, the fire holes close to the air inlet are particularly prone to flame separation, while the flames at the fire holes far away from the air inlet are smaller, resulting in uneven flames in the burner. In order to solve the above problem, some flame dividers enhance the diversion effect by arranging a flat guide plate above the air inlet, but the flat guide plate will be deformed when subjected to the impact force of the gas, thereby affecting the diversion effect of the guide plate. Summary of the Invention

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a fire distributor is provided, and the technical solution is as follows.

[0004] The fire divider includes an outer ring wall, an inner ring wall, a bottom wall and a guide plate. The bottom wall is connected between the bottom of the outer ring wall and the bottom of the inner ring wall. The outer ring wall, the inner ring wall and the bottom wall together form an air mixing chamber. An air inlet hole is provided on the bottom wall. The guide plate is arranged in the air mixing chamber through a support leg and is located above the air inlet hole. The projection of the guide plate on the bottom wall at least partially covers the air inlet hole. In the radial direction of the fire divider, the guide plate has a protrusion protruding away from the bottom wall. The protrusion extends from one end of the guide plate to the other end along the circumferential direction of the fire divider. The protrusion forms an airflow buffer chamber on the surface of the guide plate facing the bottom wall.

[0005] When the flame divider of the present invention is applied to a burner, after the gas rushes out from the air inlet and enters the gas mixing chamber, the gas will rush towards the guide plate, causing the guide plate to be subjected to the impact force of the gas. By providing a protrusion protruding away from the bottom wall on the guide plate, an airflow buffer chamber is formed on the surface of the guide plate facing the bottom wall, which can buffer the gas when it contacts the guide plate, thereby avoiding the problem of the guide plate being deformed by the impact force of the gas. In addition, the gas blocked by the guide plate can also be guided along the airflow buffer chamber to enhance the guiding effect of the guide plate, so that the gas outlet from the fire holes on the entire circle of the fire cover of the burner is uniform, avoiding the phenomenon of uneven flames ejected from the fire holes.

[0006] Exemplarily, the deflector has an outer edge facing the outer annular wall and an inner edge facing the inner annular wall, with a gap between the inner edge and the inner annular wall. The raised portion includes a first raised portion and a second raised portion, with the first raised portion being closer to the inner edge than the second raised portion. With this arrangement, a first airflow buffer cavity is formed by the first raised portion near the inner edge, and a second airflow buffer cavity is formed by the second raised portion near the outer edge. This reduces the impact force of gas on the deflector, thereby preventing deformation of the deflector due to the impact force of gas.

[0007] For example, the guide plate is provided with multiple rows of vent groups along the radial direction of the ignition distributor, with each row of vent groups comprising multiple vents located on the same circumference. This arrangement allows gas to flow through the multiple rows of vent groups to the fire outlets on the fire cover near the air inlet, thereby meeting the gas flow requirements of the fire outlets.

[0008] For example, at least one row of vent groups is located on the first protrusion. In this arrangement, when the vent group is located on the first protrusion, the first airflow buffer cavity can decelerate the airflow entering the vent group to a certain extent, thereby enhancing the deceleration effect of the vent group.

[0009] For example, at least one row of vent groups is located on the second raised portion. In this arrangement, when the vent group is located on the second raised portion, the second airflow buffer cavity can decelerate the airflow entering the vent group to a certain extent, thereby enhancing the deceleration effect of the vent group.

[0010] For example, the deflector forms an intermediate plate between the first and second raised portions, with at least one row of vent groups located on the intermediate plate. This arrangement facilitates the arrangement of multiple rows of vent groups and avoids densely packed vent groups that would result in poor airflow deceleration.

[0011] For example, the multiple rows of vent holes are sequentially divided into a first hole group, a second hole group, and a third hole group from the inner edge toward the outer edge. This arrangement allows the first, second, and third hole groups to meet the gas flow required by the fire holes on the fire cover near the air inlet, while the deflector effectively guides the gas flow.

[0012] For example, the deflector forms an intermediate plate body between the first and second raised portions, with the first hole group located on the first raised portion, the second hole group located on the intermediate plate body, and the third hole group located on the second raised portion. This arrangement avoids a dense arrangement of the first, second, and third hole groups, and by locating the first hole group on the first raised portion and the second hole group on the second raised portion, the deceleration effect of the vent hole groups is enhanced.

[0013] For example, the plurality of vent holes in the first hole group are located on a circumference with a diameter D1 of 75 mm to 80 mm. This arrangement prevents the deflector from excessively blocking the air inlet holes, thereby affecting the flow rate of the central airflow out of the air inlet holes and thus affecting the primary air injection capability.

[0014] For example, the plurality of vent holes on the second hole group are located on a circumference with a diameter D2, where D2 is 90 mm to 95 mm. This arrangement facilitates gas to flow through the plurality of vent holes to the fire outlet holes on the fire cover.

[0015] For example, the plurality of vent holes in the third hole group are located on a circumference with a diameter D3, where D3 is 105 mm to 110 mm. This arrangement prevents the outer edge of the guide plate from being too far from the air inlet, thereby reducing the primary air injection capacity.

[0016] For example, the vent holes in at least one of the vent hole groups are staggered with the vent holes in the remaining vent hole groups. With this arrangement, the deflector can effectively guide the air flow and evenly reduce the air velocity of the fire holes on the fire cover near the air inlet, thereby ensuring a uniform air velocity across the entire circle of fire holes on the fire cover.

[0017] For example, the center lines of two adjacent vent holes in the same row of vent holes form an angle of 8° to 12° with each other. This arrangement prevents the exhaust speed of the fire holes on the fire cover close to the air inlet from being too fast, thereby preventing the flame from lifting.

[0018] For example, the diameter of the vent hole is 2.5mm to 3.5mm. A vent hole diameter within this range ensures that gas can flow through the vent hole to the fire outlet hole on the fire cover near the air inlet, and effectively decelerates the airflow. If the diameter is too large, the deceleration effect is poor, and flame separation is likely to occur. If the diameter is too small, excessive deceleration is likely to occur, resulting in a smaller flame.

[0019] For example, the outer edge is configured as an arc with a radius R1 of 55mm to 60mm. This configuration allows the deflector to effectively block the flow while avoiding situations where the outer edge radius is too large, which would result in an excessively large flow-blocking area of ​​the deflector and reduce the primary air ejection capability, and where the outer edge radius is too small, which would result in an excessively small flow-blocking area of ​​the deflector and cause flame lift.

[0020] For example, the central angle of the outer edge is 80° to 120°. Within this central angle range, the deflector has a good diversion effect and effectively blocks the gas, preventing the gas from being directly transported to the fire holes on the fire cover near the air inlet, which would cause flame lift. If the angle is too large, the deflector will cause too much resistance to the gas, resulting in smaller flames from some fire holes. If the angle is too small, the deflector will cause too little resistance to the gas, resulting in flame lift from some fire holes.

[0021] For example, the inner edge is configured as an arc with a radius r1 of 30 mm to 40 mm. Within this range, the inner edge radius effectively blocks the flow, while avoiding an excessively large inner edge radius that would result in an excessively large flow-blocking area of ​​the guide plate and reduce the primary air ejection capability, and an excessively small inner edge radius that would result in an excessively small flow-blocking area of ​​the guide plate and cause flame lift.

[0022] For example, the gap is 2mm to 5mm. With this arrangement, part of the gas entering from the air inlet will flow through the gap to the fire outlet on the fire cover near the air inlet. This part of the gas will flow over the vent. Because the flow direction of the gas passing through the vent is different from the flow direction of the gas flowing out through the gap, the two air flows collide and fully mix, making the mixed air flow have no obvious directionality, thereby making the air outlet speed of the fire outlet on the fire cover near the air inlet more uniform and stable.

[0023] For example, the first protrusion and / or the second protrusion are configured as a quarter arc segment. This configuration provides a better buffering effect of the arc segment, thereby effectively preventing the guide plate from being deformed by the impact force of the gas.

[0024] For example, the guide plate is provided with an air supply hole, and the projection of the air supply hole on the bottom wall falls into the air inlet. This arrangement prevents the guide plate from affecting the flow rate of the central airflow flowing out of the air inlet, thereby preventing the guide plate from affecting the primary air ejection capacity.

[0025] For example, the air supply hole is located on the first raised portion. With this arrangement, the central airflow can be decelerated by passing through the first airflow buffer chamber when flowing from the air inlet to the air supply hole, so that the deflector has a moderate effect on the flow rate of the central airflow, preventing the central airflow from flowing too fast when it flows to the fire outlet on the fire cover, and preventing the central airflow from flowing too slowly and reducing the primary induced airflow capability.

[0026] For example, the diameter of the air supply hole is 4 mm to 6 mm. When the diameter of the air supply hole is within this range, the influence of the guide plate on the velocity of the central air flow out of the air inlet can be effectively reduced, and the primary air ejection capability can be avoided from being affected.

[0027] Exemplarily, the guide plate has a first end edge and a second end edge in the circumferential direction of the fire divider, the first end edge is closer to the air inlet than the second end edge, the first end edge has a first radial section and a first inclined section connected to the first radial section and away from the outer annular wall, the second end edge has a second radial section and a second inclined section connected to the second radial section and away from the outer annular wall, the first inclined section has a first inclination angle relative to the first radial section, the second inclined section has a second inclination angle relative to the second radial section, and the first inclination angle is greater than the second inclination angle. With such a configuration, when the ignition divider is applied to the burner, the gas will be biased to rush out in a circumferential direction through the air inlet, and the first end edge is closer to the air inlet than the second end edge, and the second end edge can be closer to the direction of airflow deflection. In this way, the guide plate can provide more shielding for the fire holes on the fire cover in the direction of airflow deflection, so that the gas outlet speed of the fire holes close to the air inlet is uniform, and a gap with a first inclination angle is formed by the first inclined section and the first radial section, further reducing the shielding of the fire holes away from the direction of airflow deflection, and a gap with a second inclination angle is formed by the second inclined section and the second radial section, reducing the shielding of the fire holes slightly away from the air inlet. However, since the gap with the second inclination angle is close to the direction of airflow deflection, the first inclination angle is set to be greater than the second inclination angle, so that the gas outlet speed of the fire holes close to the air inlet is more uniform, and the phenomenon of uneven flame ejection from the fire holes close to the air inlet is avoided.

[0028] For example, the first inclination angle is 40° to 50°. By having a notch with a first inclination angle within this range, the obstruction of the fire holes on the fire cover away from the airflow deflection direction can be reduced, thereby effectively increasing the exhaust speed of these fire holes, thereby making their exhaust speed the same as the exhaust speed of the fire holes close to the airflow deflection direction.

[0029] For example, the outer ring wall has a ring center, a first distance A is defined between an end of the first inclined segment distal from the first radial segment and the ring center, and a second distance B is defined between an end of the first inclined segment connected to the first radial segment and the ring center, with BA ranging from 9 mm to 12 mm. The gap formed by the first inclined segment and the first radial segment within this range can reduce obstruction of the fire holes on the fire cover that are located away from the direction of airflow deflection, thereby effectively increasing the exhaust velocity of these fire holes, ultimately bringing their exhaust velocity to the same as that of the fire holes located closer to the direction of airflow deflection.

[0030] For example, the second inclination angle is 25° to 35°. By having a notch with a second inclination angle within this range, the obstruction of the fire holes on the fire cover slightly away from the air inlet can be reduced, thereby effectively accelerating the exhaust speed of these fire holes, thereby making their exhaust speed the same as the exhaust speed of the fire holes close to the air inlet.

[0031] For example, the outer ring wall has a ring center, a first distance A is defined between the ring center and the end of the second inclined segment distal from the second radial segment, and a third distance C is defined between the ring center and the end of the second inclined segment connected to the second radial segment, with CA ranging from 9 mm to 12 mm. The gap formed by the second inclined segment and the second radial segment within this range can reduce obstruction of the fire holes on the fire cover slightly away from the air inlet, thereby effectively increasing the exhaust velocity of these fire holes, ultimately bringing their exhaust velocity to the same as that of the fire holes closer to the air inlet.

[0032] For example, the ratio of the minimum distance from the edge of the air inlet to the first radial segment to the minimum distance from the edge of the air inlet to the second radial segment is 4 / 7 to 2 / 3. This arrangement allows the second radial segment to be closer to the direction of airflow deflection. This allows the deflector to provide more shielding for the fire holes on the fire cover in the direction of airflow deflection, ensuring a uniform airflow velocity for those fire holes closer to the air inlet.

[0033] For example, the legs include a first leg connected to the first radial section and a second leg connected to the second radial section, and both the first leg and the second leg are fixed to the bottom wall. This arrangement enhances the stability of the deflector and prevents the deflector from shaking or falling under the impact of strong airflow.

[0034] For example, the guide plate is perpendicular to the center line of the air inlet. In this way, the guide plate has a better guiding effect and effectively blocks the gas, preventing the gas from being directly transported to the fire outlet hole on the fire cover near the air inlet, which would cause flame separation.

[0035] For example, the air inlet has an outlet surface, and the guide plate has a bottom surface facing the bottom wall. A distance H is defined between the outlet surface and the bottom surface, and H is 7 mm to 16 mm. This arrangement effectively reduces the speed of airflow exiting the air inlet, preventing it from being directly delivered to the fire outlet holes on the fire cover near the air inlet, and provides a good diversion effect. If the height between the bottom surface and the outlet surface is too high, the burner height will increase, thereby increasing costs. If the height between the bottom surface and the outlet surface is too low, the diversion effect of the guide plate will be weakened.

[0036] According to another aspect of the present invention, a burner is provided, comprising a flame cover and the flame distributor as described above, the flame cover being mounted on the flame distributor. Since the flame distributor as described above has the aforementioned beneficial effects, a burner including the flame distributor as described above also has the aforementioned beneficial effects, which will not be described in detail here.

[0037] For example, the fire cover is provided with multiple fire holes, with a distance d between the fire holes and the guide plate in a direction perpendicular to the bottom wall, and d is 3mm to 10mm. This arrangement provides a good diversion effect, and the gas flow rate from the vent holes to the fire holes near the air inlet reaches the required flow rate. If the distance is too large, the diversion effect will be weakened; if the distance is too small, the gas outlet speed will be slow and combustion will be incomplete.

[0038] For example, the fire cover has an outer wall, the fire outlet is provided on the outer wall, and the outer wall is connected to the outer ring wall, and the guide plate abuts against the outer wall. This arrangement prevents gas from flowing into the fire outlet through the gap between the guide plate and the outer ring wall during use, thereby preventing flame separation.

This summary is not intended to limit the key features and essential features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0051] In the following description, a large amount of detail is provided to facilitate a thorough understanding of the present invention. However, it will be appreciated by those skilled in the art that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0052] To provide a thorough understanding of the embodiments of the present invention, a detailed description of the structure will be provided in the following description. It should be understood that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described below in detail, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0053] An embodiment of the present invention provides a flame distributor. The flame distributor provided by the present invention can be applied to a burner. The following will describe in detail an embodiment of the flame distributor according to the present invention in conjunction with the accompanying drawings.

[0054] See also Figures 1 to 5The fire divider 10 may include an outer annular wall 110, an inner annular wall 120, a bottom wall 130 and a guide plate 140. The bottom wall 130 may be connected between the bottom of the outer annular wall 110 and the bottom of the inner annular wall 120. The outer annular wall 110, the inner annular wall 120 and the bottom wall 130 may together form an air mixing chamber 150. An air inlet hole 131 may be provided on the bottom wall 130. The guide plate 140 may be arranged in the air mixing chamber 150 by means of a support leg and located above the air inlet hole 131, and the projection of the guide plate 140 on the bottom wall 130 at least partially covers the air inlet hole 131. In the radial direction of the fire divider 10, the guide plate 140 may have a protrusion 141 that protrudes away from the bottom wall 130. The protrusion 141 may extend from one end of the guide plate 140 to the other end along the circumferential direction of the fire distributor 10 , and the protrusion 141 forms an airflow buffer cavity 160 on a surface of the guide plate 140 facing the bottom wall 130 .

[0055] When the flame divider 10 of the present invention is applied to the burner 1, after the gas rushes out from the air inlet 131 and enters the gas mixing chamber 150, the gas will rush toward the guide plate 140, causing the guide plate 140 to be subjected to the impact force of the gas. By providing a protrusion 141 protruding away from the bottom wall 130 on the guide plate 140, an airflow buffer chamber 160 is formed on the surface of the guide plate 140 facing the bottom wall 130, which can buffer the gas when it contacts the guide plate 140, thereby avoiding the problem of deformation of the guide plate 140 due to the impact force of the gas. In addition, the gas blocked by the guide plate 140 can also be guided along the airflow buffer chamber 160 to enhance the guiding effect of the guide plate 140, so that the gas outlet from the fire holes 210 on the entire circle of the fire cover 20 of the burner 1 is uniform, avoiding the phenomenon of uneven flames ejected from the fire holes 210.

[0056] For example, referring to Figure 3 and Figure 4The deflector 140 may have an outer edge 142 facing the outer annular wall 110 and an inner edge 143 facing the inner annular wall 120. A gap 170 may be provided between the inner edge 143 and the inner annular wall 120. The raised portion 141 may include a first raised portion 1411 and a second raised portion 1412. The first raised portion 1411 may be closer to the inner edge 143 than the second raised portion 1412. With this arrangement, a first airflow buffer chamber 161 is formed by the first raised portion 1411 near the inner edge 143, and a second airflow buffer chamber 162 is formed by the second raised portion 1412 near the outer edge 142, thereby reducing the impact force of the gas on the deflector 140, thereby avoiding the problem of the deflector 140 being deformed by the impact force of the gas. In addition, a gap may be provided between the outer edge 142 and the outer annular wall 110, thereby facilitating the installation of the fire cover 20 on the fire distributor 10. It should be noted that, although in the embodiment given in the figure, the number of the first protrusions 1411 is 1 and the number of the second protrusions 1412 is 1, in the embodiment not shown, the number of the first protrusions 1411 can also be 2 or even more than 2, and the number of the second protrusions 1412 can also be 2 or more than 2.

[0057] For example, referring to Figure 3 、 Figure 5 and Figure 7 The guide plate 140 may be provided with multiple rows of vent groups along the radial direction of the ignition distributor 10. Each row of vent groups may include multiple vents 1444 located on the same circumference. This arrangement allows gas to flow through the multiple rows of vent groups to the fire outlets 210 on the fire cover 20 near the air inlet 131, thereby meeting the gas flow requirements of the fire outlets 210. Preferably, the vent groups may be arranged in two or three rows. This ensures that the gas flow requirements of the fire outlets 210 on the fire cover 20 near the air inlet 131 are met, while the guide plate 140 effectively guides the gas flow. Of course, a random arrangement of the vents 1444 is not excluded.

[0058] For example, referring to Figures 3 to 5 At least one row of vent groups can be located on the first raised portion 1411. For example, one row of vent groups can be located on the first raised portion 1411, or two rows of vent groups can be located on the first raised portion 1411, and so on. With this arrangement, when the vent groups are located on the first raised portion 1411, the first airflow buffer chamber 161 can decelerate the airflow entering the vent groups, thereby enhancing the deceleration effect of the vent groups.

[0059] For example, again referring to Figures 3 to 5At least one row of vent groups can be located on the second raised portion 1412. For example, one row of vent groups can be located on the second raised portion 1412, or two rows of vent groups can be located on the second raised portion 1412, and so on. With this arrangement, when the vent groups are located on the second raised portion 1412, the second airflow buffer chamber 162 can decelerate the airflow entering the vent groups, thereby enhancing the deceleration effect of the vent groups.

[0060] For example, see Figure 5 The guide plate 140 may form an intermediate plate 1401 between the first protrusion 1411 and the second protrusion 1412, and at least one row of vent groups may be located on the intermediate plate 1401. For example, one row of vent groups may be located on the intermediate plate 1401, or two rows of vent groups may be located on the intermediate plate 1401, and so on. This arrangement facilitates the arrangement of multiple rows of vent groups and avoids the poor airflow deceleration effect caused by densely arranged vent groups.

[0061] For example, referring to Figure 3 and Figure 5 From inner edge 143 toward outer edge 142, the multiple rows of vent holes are sequentially divided into a first hole group 1441, a second hole group 1442, and a third hole group 1443. This arrangement allows the first hole group 1441, the second hole group 1442, and the third hole group 1443 to meet the required gas flow to the fire outlet 210 on the fire cover 20 near the air inlet 131, and the deflector 140 can effectively guide the gas flow.

[0062] For example, see again Figure 5 The deflector 140 may form an intermediate plate body 1401 between the first protrusion 1411 and the second protrusion 1412. The first hole group 1441 may be located on the first protrusion 1411, the second hole group 1442 may be located on the intermediate plate body 1401, and the third hole group 1443 may be located on the second protrusion 1412. This arrangement avoids a dense arrangement of the first, second, and third hole groups 1441, 1442, and 1443. Furthermore, by locating the first hole group 1441 on the first protrusion 1411 and the second hole group 1442 on the second protrusion 1412, the deceleration effect of the vent hole groups is enhanced.

[0063] For example, referring to Figure 5 and Figure 7 The multiple vent holes 1444 in the first hole group 1441 can be located on a circumference with a diameter D1. D1 can range from 75 mm to 80 mm, for example, 75 mm, 77 mm, 80 mm, etc., with D1 being optimally 77 mm. This arrangement prevents the deflector 140 from excessively blocking the air inlet holes 131, thereby affecting the velocity of the central airflow flowing out of the air inlet holes 131 and thus the primary air injection capability.

[0064] For example, again referring to Figure 3 、 Figure 5 and Figure 7 The plurality of vent holes 1444 in the second hole group 1442 can be located on a circumference having a diameter D2. D2 can range from 90 mm to 95 mm, for example, 90 mm, 92 mm, 95 mm, etc., with D2 being optimally 92 mm. This arrangement facilitates gas flow through the plurality of vent holes 1444 to the fire outlet 210 on the fire cover 20.

[0065] For example, again referring to Figure 5 and Figure 7 The plurality of vent holes 1444 in the third hole group 1443 can be located on a circumference having a diameter D3. D3 can range from 105 mm to 110 mm, for example, 105 mm, 108 mm, 110 mm, etc., with D3 being optimally 108 mm. This arrangement prevents the outer edge 142 of the deflector 140 from being too far from the air inlet 131, thereby reducing the primary air injection capability.

[0066] For example, once again referring to Figure 3 、 Figure 5 and Figure 7 The vent holes 1444 in at least one of the vent hole groups can be staggered with the vent holes 1444 in the remaining vent hole groups. Preferably, the vent holes 1444 in the first hole group 1441, the vent holes 1444 in the second hole group 1442, and the vent holes 1444 in the third hole group 1443 are all staggered. With this arrangement, the deflector 140 can effectively guide the air flow and evenly reduce the exhaust velocity of the fire holes 210 on the fire cover 20 near the air inlet 131, thereby ensuring a uniform exhaust velocity for the fire holes 210 along the entire circle of the fire cover 20.

[0067] For example, referring to Figure 3 and Figure 7 The center lines of two adjacent vent holes 1444 in the same row of vent holes can form an angle γ of 8° to 12°. For example, the angle γ can be 8°, 10°, 12°, etc., with the optimal angle γ being 10°. This configuration prevents the flame holes 210 on the fire cover 20 near the air inlet 131 from escaping the flame from being too fast, thereby preventing flame lift.

[0068] For example, once again referring to Figure 3 、 Figure 5 and Figure 7The diameter d1 of the vent hole 1444 can be 2.5 mm to 3.5 mm, for example, 2.5 mm, 3 mm, 3.5 mm, etc., with the most preferred diameter d1 being 3 mm. The diameter of the vent hole 1444 within this range ensures that gas can flow through the vent hole 1444 to the fire outlet 210 on the fire cover 20 near the air inlet 131, effectively decelerating the airflow. If the diameter d1 is too large, the deceleration effect is poor, and flame separation is likely to occur. If the diameter d1 is too small, excessive deceleration is likely to occur, resulting in a smaller flame.

[0069] For example, see Figure 7 The outer edge 142 can be configured as an arc with a radius R1, which can be 55 mm to 60 mm, for example, 55 mm, 58 mm, 60 mm, etc., with 58 mm being the most preferred value. This configuration allows the deflector 140 to effectively block the flow, while preventing the outer edge 142 radius R1 from being too large, which would result in an excessively large flow-blocking area of ​​the deflector 140 and reduce the primary air ejection capability. It also prevents the outer edge 142 radius R1 from being too small, which would result in an excessively small flow-blocking area of ​​the deflector 140 and cause flame lift.

[0070] For example, again referring to Figure 3 and Figure 7 The central angle θ of the outer edge 142 can be 80° to 120°, for example, the central angle θ can be 80°, 100°, 120°, etc., and the optimal central angle θ is 100°. When the central angle θ is within this range, the guide plate 140 has a good guiding effect and effectively blocks the gas, preventing the gas from being directly transported to the fire outlet 210 on the fire cover 20 near the air inlet 131, thereby preventing the flame from being separated. If the angle is too large, the resistance caused by the guide plate 140 to the gas will be too large, resulting in a smaller flame from some of the fire outlets 210. If the angle is too small, the resistance caused by the guide plate 140 to the gas will be too small, resulting in a flame separation from some of the fire outlets 210.

[0071] For example, see again Figure 7 The inner edge 143 can be configured as an arc with a radius r1, which can be 30 mm to 40 mm, for example, 30 mm, 35 mm, 40 mm, etc., with r1 being optimally 34.5 mm. Within this range, the radius of the inner edge 143 can effectively block the flow, while preventing an excessively large radius r1 of the inner edge 143, which would result in an excessively large flow-blocking area of ​​the guide plate 140 and a reduction in the primary air entrainment capability. At the same time, the radius r1 of the inner edge 143 can be avoided, which would result in an excessively small flow-blocking area of ​​the guide plate 140 and the occurrence of flame lift.

[0072] For example, once again referring to Figures 3 to 5, the gap 170 can be 2mm to 5mm, for example, the gap 170 can be 2mm, 2.5mm, 5mm, etc., and the gap 170 is preferably 2.5mm. It should be understood that the gap 170 corresponds to the distance S between the inner edge 143 and the inner surface of the inner ring wall 120. In this way, part of the gas entering from the air inlet 131 will flow through the gap 170 to the fire outlet 210 on the fire cover 20 near the air inlet 131, and this part of the gas will flow over the vent 1444. Since the flow direction of the gas passing through the vent 1444 is different from the flow direction of the gas flowing out through the gap 170, the two air flows collide and are fully mixed, so that the mixed air flow has no obvious directionality, thereby making the gas outlet speed of the fire outlet 210 on the fire cover 20 near the air inlet 131 more uniform and stable.

[0073] For example, referring to Figures 3 to 6 , the first protrusion 1411 and / or the second protrusion 1412 can be configured as a 1 / 4 arc segment. Preferably, the first protrusion 1411 and the second protrusion 1412 can be configured as a 1 / 4 arc segment, that is, the central angle of the first protrusion 1411 is 90°, and the central angle of the second protrusion 1412 is also 90°. With this arrangement, the buffering effect of the arc segment is better, thereby effectively preventing the guide plate 140 from being deformed by the impact force of the gas. When the first hole group 1441 is located on the first protrusion 1411, and the diameter d1 of the vent hole 1444 on the first hole group 1441 is 3 mm, the radius of the 1 / 4 arc segment of the first protrusion 1411 can be greater than 3 mm. When third hole group 1443 is located on second protrusion 1412, and diameter d1 of vent holes 1444 on third hole group 1443 is 3 mm, the radius of the quarter arc segment of second protrusion 1412 can be greater than 3 mm. Of course, it is not ruled out that first protrusion 1411 or second protrusion 1412 can be configured as a quarter arc segment.

[0074] For example, see again Figure 5 The guide plate 140 may be provided with an air supply hole 145, the projection of which on the bottom wall 130 may fall within the air inlet hole 131. This arrangement prevents the guide plate 140 from affecting the velocity of the central airflow exiting the air inlet hole 131, thereby preventing the guide plate 140 from affecting the primary air ejection capability. Optionally, the air supply hole 145 may be located in the middle of the plurality of vent holes 1444 in the first hole group 1441. When the central axis of the air supply hole 145 coincides with the central axis of the air inlet hole 131, the effect of preventing the guide plate 140 from affecting the primary air ejection capability is optimal.

[0075] For example, once again referring to Figure 3 、 Figure 5 and Figure 7The air supply hole 145 can be located on the first protrusion 1411. With this arrangement, the central airflow can be decelerated by passing through the first airflow buffer cavity 161 when flowing from the air inlet hole 131 to the air supply hole 145, so that the deflector 140 has a moderate effect on the flow rate of the central airflow, preventing the central airflow from being too fast when flowing to the fire outlet 210 on the fire cover 20, and preventing the central airflow from being too slow and reducing the primary induced airflow capability.

[0076] For example, once again referring to Figure 5 and Figure 7 The diameter d2 of the air supply hole 145 can be 4 mm to 6 mm, for example, 4 mm, 5 mm, 6 mm, etc., with the optimal diameter d2 being 5 mm. Within this range, the diameter d2 of the air supply hole 145 can effectively reduce the impact of the guide plate 140 on the velocity of the central airflow flowing out of the air inlet 131 and avoid affecting the primary air ejection capability. When the air supply hole 145 is located on the first protrusion 1411 and the diameter d2 of the air supply hole 145 is 5 mm, the radius of the 1 / 4 arc segment of the first protrusion 1411 can be greater than 5 mm.

[0077] For example, referring to Figures 3 to 7The guide plate 140 may have a first end edge 146 and a second end edge 147 in the circumferential direction of the fire divider 10. The first end edge 146 may be closer to the air inlet 131 than the second end edge 147. The first end edge 146 may have a first radial section 1461 and a first inclined section 1462 connected to the first radial section 1461 and away from the outer annular wall 110. The second end edge 147 may have a second radial section 1471 and a second inclined section 1472 connected to the second radial section 1471 and away from the outer annular wall 110. The first inclined section 1462 may have a first inclination angle α relative to the first radial section 1461, and the second inclined section 1472 may have a second inclination angle β relative to the second radial section 1471. The first inclination angle α may be greater than the second inclination angle β. With such a configuration, when the ignition distributor 10 is applied to the burner 1, the gas will be biased and rushed out along the circumferential direction through the air inlet hole 131, and the first end edge 146 is closer to the air inlet hole 131 than the second end edge 147. The second end edge 147 can be closer to the direction of air flow deflection. In this way, the guide plate 140 can provide more shielding for the fire outlet holes 210 on the fire cover 20 in the direction of air flow deflection, so that the air outlet speed of the fire outlet holes 210 close to the air inlet hole 131 is uniform, and a gap with a first inclination angle α is formed by the first inclined section 1462 and the first radial section 1461. , further reducing the obstruction of the fire holes 210 away from the air flow deflection direction, a gap with a second inclination angle β is formed by the second inclined section 1472 and the second radial section 1471, reducing the obstruction of the fire holes 210 slightly away from the air inlet hole 131. However, since the gap with the second inclination angle β is close to the air flow deflection direction, the first inclination angle α is set to be greater than the second inclination angle β, so that the exhaust speed of the fire holes 210 close to the air inlet hole 131 is more uniform, and the phenomenon of uneven flame ejection from the fire holes 210 close to the air inlet hole 131 is avoided.

[0078] For example, referring to Figure 3 、 Figure 5 and Figure 6 The first inclination angle α can be 40° to 50°, for example, 40°, 45°, 50°, etc., with the most preferred first inclination angle α being 45°. The gaps having a first inclination angle α within this range can reduce obstruction of the fire holes 210 on the fire cover 20 that are away from the direction of airflow deflection, thereby effectively increasing the gas outlet velocity of these fire holes 210, thereby making their gas outlet velocity the same as that of the fire holes 210 that are close to the direction of airflow deflection.

[0079] For example, again referring to Figure 3 and Figure 5, the outer ring wall 110 may have a ring center, a first distance A may be present between the end of the first inclined section 1462 away from the first radial section 1461 and the ring center, a second distance B may be present between the end of the first inclined section 1462 connected to the first radial section 1461 and the ring center, and BA may be between 9 mm and 12 mm. For example, BA may be 9 mm, 10 mm, 12 mm, and so on, and BA is preferably 11 mm. The gap formed by the first inclined section 1462 and the first radial section 1461 within this range can reduce the obstruction of the fire holes 210 on the fire cover 20 away from the direction of airflow deflection, thereby effectively accelerating the gas outlet speed of these fire holes 210, and further making their gas outlet speed the same as the gas outlet speed of the fire holes 210 close to the direction of airflow deflection.

[0080] For example, again referring to Figure 3 、 Figure 5 and Figure 6 The second inclination angle β can be between 25° and 35°, for example, 25°, 30°, 35°, etc., with the optimal second inclination angle β being 30°. The notches having a second inclination angle β within this range can reduce obstruction of the fire holes 210 on the fire cover 20 slightly away from the air inlet 131, thereby effectively increasing the gas outlet speed of these fire holes 210, thereby making their gas outlet speed the same as that of the fire holes 210 closer to the air inlet 131.

[0081] For example, once again referring to Figure 3 and Figure 5 The outer ring wall 110 may have a ring center, a first distance A may be present between the end of the second inclined section 1472 away from the second radial section 1471 and the ring center, a third distance C may be present between the end of the second inclined section 1472 connected to the second radial section 1471 and the ring center, and CA may be between 9 mm and 12 mm. For example, CA may be 9 mm, 10 mm, 12 mm, and so on, and CA is preferably 11 mm. The gap formed by the second inclined section 1472 and the second radial section 1471 within this range can reduce the obstruction of the fire holes 210 on the fire cover 20 that are slightly away from the air inlet 131, thereby effectively accelerating the gas outlet speed of these fire holes 210, and further making their gas outlet speed the same as the gas outlet speed of the fire holes 210 close to the air inlet 131.

[0082] For example, once again referring to Figure 3 and Figure 5The ratio of the minimum distance between the edge of the air inlet hole 131 and the first radial segment 1461 to the minimum distance between the edge of the air inlet hole 131 and the second radial segment 1471 can be 4 / 7 to 2 / 3, for example, 4 / 7, 3 / 5, 2 / 3, etc., with 3 / 5 being the most preferred. Specifically, the minimum distance between the edge of the air inlet hole 131 and the first radial segment 1461 can be the shortest distance H between the tangent point of the arc on the edge of the air inlet hole 131 and the first radial segment 1461, and the minimum distance between the edge of the air inlet hole 131 and the second radial segment 1471 can be the shortest distance L between the tangent point of the arc on the edge of the air inlet hole 131 and the second radial segment 1471. With this arrangement, the second radial segment 1471 can be closer to the direction of airflow deflection. This allows the deflector 140 to provide greater shielding for the fire holes 210 on the fire cover 20 in the direction of airflow deflection, ensuring a uniform airflow velocity for the fire holes 210 near the air inlet hole 131.

[0083] For example, referring to Figure 4 and Figure 5 The legs may include a first leg 180 and a second leg 190. The first leg 180 may be connected to the first radial section 1461, and the second leg 190 may be connected to the second radial section 1471. Both the first leg 180 and the second leg 190 may be fixed to the bottom wall 130. This arrangement enhances the stability of the deflector 140 and prevents the deflector 140 from shaking or falling under the impact of strong airflow. The first leg 180 may be welded to the bottom wall 130, or alternatively, may be fixed by adhesive or other methods. The second leg 190 may be welded to the bottom wall 130, or alternatively, may be fixed by adhesive or other methods. Of course, the deflector 140 and the fire distributor 10 may also be integrally formed. The first leg 180 may be divided into a first supporting section 181 and a first fixing section 182. The first supporting section 181 and the first fixing section 182 may form an L-shape. It is understood that the first supporting section 181 can be used to support the deflector 140, and the first fixing section 182 can be used to connect to the bottom wall 130. The first fixing section 182 can extend toward the inner annular wall 120 or the outer annular wall 110. This increases the connection area between the first fixing section 182 and the bottom wall 130, further enhancing the stability of the deflector 140. The second leg 190 can be divided into a second supporting section 191 and a second fixing section 192. The second supporting section 191 and the second fixing section 192 can form an L-shape. It is understood that the second supporting section 191 can be used to support the deflector 140, and the second fixing section 192 can be used to connect to the bottom wall 130. The second fixing section 192 can extend toward the inner annular wall 120 or the outer annular wall 110. This increases the connection area between the second fixing section 192 and the bottom wall 130, further enhancing the stability of the deflector 140.

[0084] For example, see Figure 3 The deflector 140 can be perpendicular to the centerline of the air inlet 131. Specifically, the centerline XX of the air inlet 131 is perpendicular to the bottom surface 148 of the deflector 140, described below. This arrangement improves the deflector 140's diversion effect and effectively blocks gas, preventing it from being directly transported to the fire outlet 210 on the fire cover 20 near the air inlet 131 and causing flame lift.

[0085] For example, see again Figure 3 The air inlet 131 may have an air outlet surface 1311, and the guide plate 140 may have a bottom surface 148 facing the bottom wall 130. A distance H may be provided between the air outlet surface 1311 and the bottom surface 148. H may be 7 mm to 16 mm, for example, H may be 7 mm, 11 mm, 16 mm, etc., and H is preferably 11 mm. This arrangement effectively reduces the speed of the airflow rushing out of the air inlet 131, preventing it from being directly delivered to the fire outlet 210 on the fire cover 20 near the air inlet 131, and has a good guiding effect. If the height of the bottom surface 148 and the air outlet surface 1311 is too high, the height of the burner 1 will increase, thereby increasing the cost. If the height of the bottom surface 148 and the air outlet surface 1311 is too low, the guiding effect of the guide plate 140 will be weakened.

[0086] According to another aspect of the present invention, a burner is provided. Figure 1 The burner 1 may include a fire cover 20 and the aforementioned flame distributor 10. The fire cover 20 may be mounted on the flame distributor 10. Since the aforementioned flame distributor 10 has the aforementioned beneficial effects, the burner 1 including the aforementioned flame distributor 10 also has the aforementioned beneficial effects, which will not be described in detail here.

[0087] For example, once again referring to Figure 3 and Figure 5 The fire cover 20 may be provided with a plurality of fire holes 210. A distance d may be provided between the fire holes 210 and the deflector 140 in a direction perpendicular to the bottom wall 130. The distance d may range from 3 mm to 10 mm, for example, 3 mm, 7 mm, 10 mm, etc., with 5 mm being the most preferred. This arrangement provides a better diversion effect, and the gas flow rate from the vent holes 1444 to the fire holes 210 near the air inlet 131 reaches the desired flow rate. If the distance is too large, the diversion effect will be weakened; if the distance is too small, the gas outlet speed will be slow and combustion will be incomplete.

[0088] For example, once again referring to Figures 3 to 5The fire cover 20 may include an outer wall 220. The fire outlet 210 may be provided on the outer wall 220, and the outer wall 220 may be connected to the outer annular wall 110. The deflector 140 may abut against the outer wall 220. The outer wall 220 may be positioned in the gap between the outer edge 142 and the outer annular wall 110. This arrangement prevents gas from flowing into the fire outlet 210 through the gap between the deflector 140 and the outer annular wall 110 during use, thereby preventing flame lift.

[0089] See also Figures 1 to 7, the gas flow process of the burner 1 when in use is as follows: the gas enters the mixing chamber 150 through the air inlet hole 131, and the gas will be biased and rushed out in the circumferential direction. The air flow buffer chamber 160 formed by the protrusion 141 is buffered to prevent the guide plate 140 from being deformed by the impact force of the gas. Then, through the guiding effect of the guide plate 140, the gas is diverted along the circumferential direction of the burner 1 to those fire holes 210 away from the air inlet hole 131. A part of the gas is decelerated through the first hole group 1441, the second hole group 1442 and the third hole group 1443 to flow to those fire holes 210 close to the air inlet hole 131. Among them, the first hole group 1441 is located on the first protrusion 1411, and the gas can be decelerated by the first air flow buffer chamber 161 and the first hole group 1441, and the third hole group 1443 Located on the second protrusion 1412, the gas can be decelerated by the second airflow buffer cavity 162 and the third hole group 1443; another part of the gas flows through the gap 170 between the inner edge 143 and the inner ring wall 120 to the fire holes 210 near the air inlet hole 131. This part of the gas will flow over the first hole group 1441, the second hole group 1442 and the third hole group 1443. Since the flow direction of the gas passing through the first hole group 1441, the second hole group 1442 and the third hole group 1443 is different from the flow direction of the gas flowing out through the gap 170, the two air flows collide and are fully mixed, so that the mixed air flow has no obvious directionality, thereby making the air outlet speed of the fire holes 210 on the fire cover 20 near the air inlet hole 131 more uniform and stable. The first end edge 146 is closer to the air inlet 131 than the second end edge 147, and the second end edge 147 can be closer to the direction of air flow deflection. In this way, the guide plate 140 can provide more shielding for the fire holes 210 in the direction of air flow deflection, so that the air outlet velocity of the fire holes 210 close to the air inlet 131 is uniform, and a gap with a first inclination angle α is formed by the first inclined section 1462 and the first radial section 1461, further reducing the shielding of the fire holes 210 away from the direction of air flow deflection. A gap with a second inclination angle β is formed by the second inclined section 1472 and the second radial section 1471, reducing the shielding of the fire holes 210 slightly away from the air inlet 131. However, since the gap with the second inclination angle β is close to the direction of air flow deflection, by setting the first inclination angle α to be greater than the second inclination angle β, the air outlet velocity of the fire holes 210 close to the air inlet 131 is more uniform, and the phenomenon of uneven flame ejection from the fire holes 210 close to the air inlet 131 is avoided. In summary, the gas outlet speed of the fire outlet holes 210 of the entire circle of the fire cover 20 is uniform, and the flames ejected from the fire outlet holes 210 of the entire circle of the fire cover 20 are uniform.
