Description

Technical Field

[0001] The present invention relates to the field of gas burners, and in particular to a distribution component, a combustion chamber box and a burner. Background Art

[0002] Existing burners will have a distribution component installed in the air chamber to distribute the air flowing into the combustion chamber. One part (primary air intake) is used to mix with the gas, and the other part (secondary air intake) is used to supply oxygen to the burning gas. However, the existing distribution components are all fixed. One end of the distribution component abuts against the inner wall of the air chamber, dividing the main air inlet into two parts according to a certain ratio, thereby controlling the ratio between the primary and secondary air intakes. However, under this structure, the ratio between the primary and secondary air intakes is fixed. Since the regions and seasons in which the water heaters are used are not exactly the same, there will be some errors in the product itself. The fixed ratio will lead to incomplete combustion of the burner, resulting in excessive CO content and low combustion efficiency of the water heater. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the primary air inlet and secondary air inlet ratio of the burner is fixed, resulting in low combustion efficiency, and provide a distribution component, a combustion chamber box and a burner.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A distribution component is applied to a combustion chamber box, the combustion chamber box is provided with an air inlet, the distribution component includes a first plate and a second plate, the second plate is movably arranged on the first plate; the first plate is rotatably arranged in the combustion chamber box and is located above the air inlet, the end of the second plate away from the first plate abuts against the air inlet, and the air inlet is divided into a first air inlet and a second air inlet; the rotation of the first plate drives the second plate to move along the first plate to change the size of the first air inlet and the second air inlet.

[0006] In this embodiment, a second plate is movably mounted on the first plate. As the first plate rotates above the air inlet, the end of the second plate facing away from the first plate moves relative to the air inlet, thereby changing the area of the air inlets on either side of the second plate, thereby altering the size of the first and second air inlets. The second plate rotates with the first plate. As the angle between the second plate and the plane containing the air inlets gradually increases, the inner wall of the combustion chamber at the air inlet exerts a force on the second plate toward the first plate, causing the second plate to move toward the first plate and shorten the distribution assembly. As the angle between the second plate and the plane containing the air inlet gradually decreases, the second plate becomes suspended in the air and, under the action of gravity, moves away from the first plate, lengthening the distribution assembly. With this structural form, as the first plate rotates, one end of the distribution assembly can remain in contact with the air inlet, allowing for flexible and precise adjustment of the primary and secondary air ratios.

[0007] Preferably, the axial direction of rotation of the first plate body is a first direction, the direction in which the second plate body moves along the first plate body is a second direction, and the second direction is perpendicular to the first direction.

[0008] In this solution, the second direction is perpendicular to the axial direction of rotation of the first plate, and the force applied by the inner wall of the combustion chamber box at the air inlet to the second plate has little loss in the second direction. The second plate moves more smoothly relative to the first plate and is not prone to jamming.

[0009] Preferably, a slide rail is provided on at least one side of the first plate body along the second direction, and the side of the second plate body along the second direction can be movably clamped in the slide rail.

[0010] This solution adopts the above-mentioned structural form, and the second plate body can slide in the slide rail provided on the side of the first plate body, thereby realizing the purpose of moving along the second direction relative to the first plate body. This structure is simple, and the sliding of the second plate body relative to the first plate body is reliable.

[0011] Preferably, the slide rail is provided with a first groove and a second groove, the side of the first plate body is fixedly connected to the first groove, and the side of the second plate body is slidably fitted with the second groove.

[0012] In this solution, the slide rail is fixedly connected to the side of the first plate through the first groove, and the second plate slides in cooperation with the second groove. The movable connection between the first plate and the second plate is simple, reliable, and has low manufacturing cost.

[0013] Preferably, a limiting portion is provided on a side of the second plate body along the second direction, and the limiting portion enables the side of the second plate body to remain within the slide rail.

[0014] In this solution, the above structure is adopted. When the first plate body rotates, the second plate body moves on the first plate body along the second direction. Because the side of the second plate body along the second direction is provided with a limiting portion, the side of the second plate body can be kept in the slide rail, and the first plate body and the second plate body will not separate.

[0015] Preferably, the distribution assembly includes a rotating shaft, which is rotatably arranged in the combustion chamber box, and the first plate is fixedly arranged on the side wall of the rotating shaft along the side of the first direction.

[0016] In this solution, the side of the first plate along the first direction is rotatably arranged on the inner wall of the combustion chamber box through the rotating shaft, which has a simple and reliable structure and low manufacturing cost.

[0017] Preferably, the distribution assembly includes a motor, and the output end of the motor is connected to the rotating shaft through a gear.

[0018] With the above structure, the motor is controlled to rotate the shaft, thereby realizing the rotation of the first plate. The process of changing the ratio of the first air intake and the second air intake is highly automated and easy to operate.

[0019] Preferably, the distribution assembly includes a connecting portion, the connecting portion is fixedly arranged in the combustion chamber, and the rotating shaft is rotatably arranged on the connecting portion.

[0020] In this solution, the rotating shaft is rotatably arranged on the inner wall of the combustion chamber box through the connecting portion, the structure is simple and reliable, and the manufacturing cost is low.

[0021] A combustion chamber box is provided with the above distribution assembly.

[0022] In this embodiment, the second plate of the combustion chamber box is movably mounted on the first plate. As the first plate rotates above the air inlet, the end of the second plate away from the first plate moves at the air inlet, thereby changing the area of the air inlets on either side of the second plate, thereby altering the size of the first and second air inlets. The second plate rotates with the first plate. As the angle between the second plate and the plane containing the air inlets increases, the inner wall of the combustion chamber box at the air inlet exerts a force on the second plate toward the first plate, causing the second plate to move toward the first plate and shortening the distribution assembly. As the angle between the second plate and the plane containing the air inlet decreases, the second plate becomes suspended in the air and, under the action of gravity, moves away from the first plate, lengthening the distribution assembly. With this structural design, as the first plate rotates, one end of the distribution assembly can remain in contact with the air inlet, allowing for flexible and precise adjustment of the primary and secondary air ratios, resulting in higher combustion efficiency in the combustion chamber box.

[0023] Preferably, the combustion chamber box includes a first air inlet channel connected to the first air inlet and a second air inlet channel connected to the second air inlet; the distribution assembly includes a connecting portion, which is fixedly arranged at the junction of the first air inlet channel and the second air inlet channel.

[0024] In this solution, the connecting portion is fixedly arranged at the junction of the first air inlet channel and the second air inlet channel, so that the distribution component is blocked between the first air inlet channel and the second air inlet channel, the primary air inlet and the secondary air inlet will not be mixed, and the matching accuracy is high.

[0025] Preferably, the combustion chamber box is provided with a first air supply port and a second air supply port, the first air supply port is connected to the first air inlet channel, and the second air supply port is connected to the second air inlet channel; the connecting part is fixedly arranged between the first air supply port and the second air supply port, and the first plate body can be rotatably arranged on the connecting part.

[0026] In this solution, the first air inlet channel delivers primary air through the first air supply port to a designated location for mixing with the fuel gas. The second air inlet channel delivers secondary air through the second air supply port to a designated location to provide oxygen to the combustion area. A connection portion is fixedly positioned between the first and second air supply ports, separating the distribution assembly from the first and second air inlet channels. This prevents mixing of the primary and secondary air, ensuring a highly accurate mixing ratio.

[0027] A burner comprises the above distribution assembly, or the above combustion chamber box.

[0028] In this embodiment, the burner's second plate is movably mounted on the first plate. As the first plate rotates above the air inlet, the end of the second plate facing away from the first plate moves relative to the air inlet, thereby changing the area of the air inlets on either side of the second plate, thereby altering the size of the first and second air inlets. The second plate rotates with the first plate. As the angle between the second plate and the plane containing the air inlets increases, the inner wall of the combustion chamber at the air inlet exerts a force on the second plate toward the first plate, causing the second plate to move toward the first plate and shorten the distribution assembly. As the angle between the second plate and the plane containing the air inlet decreases, the second plate becomes suspended in the air and, under the action of gravity, moves away from the first plate, lengthening the distribution assembly. With this structural design, one end of the distribution assembly can remain in contact with the air inlet as the first plate rotates, allowing for flexible and precise adjustment of the primary and secondary air ratios, resulting in a high combustion efficiency for the burner.

[0029] The present invention provides a positive and advantageous effect: the second plate is movably mounted on the first plate. As the first plate rotates above the air inlet, the end of the second plate away from the first plate moves at the air inlet, thereby changing the area of the air inlets on either side of the second plate, thereby changing the size of the first and second air inlets. As the second plate rotates with the first plate, as the angle between the second plate and the plane containing the air inlets gradually increases, the inner wall of the combustion chamber at the air inlet exerts a force on the second plate toward the first plate, causing the second plate to move toward the first plate and shorten the distribution assembly. As the angle between the second plate and the plane containing the air inlet gradually decreases, the second plate becomes suspended in the air and, under the action of gravity, moves away from the first plate, lengthening the distribution assembly. With this structural form, as the first plate rotates, one end of the distribution assembly can always remain in contact with the air inlet, allowing for flexible and precise adjustment of the primary and secondary air ratios, resulting in higher gas combustion efficiency.

[0052] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0053] like Figure 1-Figure 3 As shown, this embodiment provides a distribution component 1, which is applied to a combustion chamber box. The combustion chamber box is provided with an air inlet 2. The distribution component 1 includes a first plate body 11 and a second plate body 12. The second plate body 12 is movably arranged on the first plate body 11; the first plate body 11 is rotatably arranged in the combustion chamber box and is located above the air inlet 2, and the end of the second plate body 12 away from the first plate body 11 abuts against the air inlet 2 and divides the air inlet 2 into a first air inlet and a second air inlet 2; the rotation of the first plate body 11 drives the second plate body 12 to move along the first plate body 11 to change the size of the first air inlet and the second air inlet 2.

[0054] In this embodiment, the second plate 12 is movably mounted on the first plate 11. As the first plate 11 rotates above the air inlet 2, the end of the second plate 12 away from the first plate 11 moves at the air inlet 2, thereby changing the area of the air inlets 2 on both sides of the second plate 12, that is, changing the size of the first and second air inlets 2. The second plate 12 rotates with the first plate 11. When the angle between the second plate 12 and the plane containing the air inlet 2 gradually increases, the inner wall of the combustion chamber box at the air inlet 2 exerts a force on the second plate 12 toward the first plate 11. At this time, the second plate 12 moves toward the first plate 11, shortening the distribution assembly 1. When the angle between the second plate 12 and the plane containing the air inlet 2 gradually decreases, the second plate 12 becomes suspended in the air. Under the action of gravity, the second plate 12 moves away from the first plate 11, shortening the distribution assembly 1. With the above-mentioned structural form, when the first plate 11 rotates, one end of the distribution component 1 can always keep in contact with the air inlet 2, so as to flexibly and accurately adjust the ratio of the primary air intake and the secondary air intake.

[0055] As a preferred embodiment, the axial direction of rotation of the first plate body 11 is the first direction, the direction in which the second plate body 12 moves along the first plate body 11 is the second direction, and the second direction is perpendicular to the first direction.

[0056] In this embodiment, the second direction is perpendicular to the axial direction of rotation of the first plate body 11. The force applied by the inner wall of the combustion chamber box at the air inlet 2 to the second plate body 12 has little loss in the second direction, and the second plate body 12 moves more smoothly relative to the first plate body 11 and is not prone to jamming.

[0057] As a preferred embodiment, a slide rail 13 is provided on each side of the first plate body 11 along the second direction, and the side edge of the second plate body 12 along the second direction is movably clamped between the two slide rails 13 .

[0058] This solution adopts the above-mentioned structural form, and the second plate body 12 can slide within the slide rails 13 provided on the side of the first plate body 11, thereby achieving the purpose of moving in the second direction relative to the first plate body 11. At the same time, because the slide rails 13 are provided on both sides of the first plate body 11, the second plate body 12 will not detach from the side of the first plate body 11. This simple structure and reliable sliding of the second plate body 12 relative to the first plate body 11.

[0059] like Figure 1 As shown, specifically, the slide rail 13 is a fixed slider, which is provided with a first groove 131 and a second groove 132 . The side of the first plate body 11 is fixedly connected to the first groove 131 , and the side of the second plate body 12 is slidably fitted with the second groove 132 .

[0060] In this embodiment, the slide rail 13 is fixedly connected to the side of the first plate 11 through the first groove 131, and the second plate 12 slides in cooperation with the second groove 132. The movable connection between the first plate 11 and the second plate 12 is simple, reliable, and has low manufacturing cost.

[0061] As a preferred embodiment, both ends of the side of the second plate body 12 along the second direction are respectively provided with limiting portions 121 , and the limiting portions 121 enable the side of the second plate body 12 to remain within the slide rail 13 .

[0062] In this embodiment, the above-mentioned structure is adopted. When the first plate body 11 rotates, the second plate body 12 moves on the first plate body 11 along the second direction. Because the second plate body 12 is provided with a limiting portion 121 on the side along the second direction, the side of the second plate body 12 can be maintained in the slide rail 13, and the first plate body 11 and the second plate body 12 will not separate.

[0063] As a preferred embodiment, the distribution assembly 1 includes a rotating shaft 14 , which is rotatably disposed in the combustion chamber box, and the first plate 11 is fixedly disposed on the side wall of the rotating shaft 14 along the side of the first direction.

[0064] In this embodiment, the side of the first plate 11 along the first direction is rotatably arranged on the inner wall of the combustion chamber box through the rotating shaft 14, which has a simple and reliable structure and low manufacturing cost.

[0065] As a preferred embodiment, one end of the rotating shaft 14 extends from the interior of the combustion chamber box, and a gear is fixedly provided on the extended portion. The distribution assembly 1 includes a motor, and the output end of the motor is gear-connected to the extended portion of the rotating shaft 14.

[0066] With the above structure, the motor is controlled to rotate the shaft 14, thereby realizing the rotation of the first plate 11. The process of changing the ratio of the first air intake and the second air intake is highly automated and easy to operate.

[0067] As a preferred embodiment, the distribution assembly 1 includes a connecting portion 15, the main body of the connecting portion 15 is annular, and the annular main body is movably sleeved on the rotating shaft 14. The annular main body is also provided with a connecting block, which is fixedly arranged in the combustion chamber.

[0068] In this embodiment, the rotating shaft 14 is rotatably arranged on the inner wall of the combustion chamber box through the connecting portion 15, which has a simple and reliable structure and low manufacturing cost.

[0069] like Figure 4 As shown, this embodiment also provides a combustion chamber box, which is provided with the above-mentioned distribution assembly 1.

[0070] In this embodiment, the second plate 12 of the combustion chamber box is movably mounted on the first plate 11. As the first plate 11 rotates above the air inlet 2, the end of the second plate 12 away from the first plate 11 moves at the air inlet 2, thereby changing the area of the air inlets 2 on both sides of the second plate 12, that is, changing the size of the first and second air inlets 2. The second plate 12 rotates with the first plate 11. When the angle between the second plate 12 and the plane containing the air inlet 2 gradually increases, the inner wall of the combustion chamber box at the air inlet 2 exerts a force on the second plate 12 toward the first plate 11. At this time, the second plate 12 moves toward the first plate 11, shortening the distribution assembly 1. When the angle between the second plate 12 and the plane containing the air inlet 2 gradually decreases, the second plate 12 becomes suspended in the air. Under the action of gravity, the second plate 12 moves away from the first plate 11, shortening the distribution assembly 1. With the above structure, when the first plate 11 rotates, one end of the distribution assembly 1 can always remain in contact with the air inlet 2, flexibly and accurately adjusting the ratio of the primary air intake and the secondary air intake, and the combustion efficiency of the combustion chamber box is higher.

[0071] like Figure 4 As shown, as a preferred embodiment, the combustion chamber box has a combustion chamber 3 on the top and an air cavity 4 on the bottom, which are separated by a partition plate 5. The air cavity 4 includes a first air inlet channel 6 connected to the first air inlet and a second air inlet channel 7 connected to the second air inlet 2; the distribution assembly 1 includes a connecting portion 15, which is fixedly arranged at the intersection of the first air inlet channel 6 and the second air inlet channel 7.

[0072] In this embodiment, the connecting portion 15 is fixedly arranged at the junction of the first air inlet channel 6 and the second air inlet channel 7, so that the distribution component 1 is blocked between the first air inlet channel 6 and the second air inlet channel 7, the primary air intake and the secondary air intake will not be mixed, and the matching accuracy is high.

[0073] As a preferred embodiment, the air cavity 4 is provided with a first air supply port 8 and a second air supply port 9. The first air supply port 8 is connected with the first air inlet channel 6 to deliver the primary air into the combustion chamber 3, and the second air supply port 9 is connected with the second air inlet channel 7 to deliver the secondary air into the combustion chamber 3; the connecting portion 15 is fixedly arranged between the first air supply port 8 and the second air supply port 9, and the first plate body 11 can be rotatably arranged on the connecting portion 15.

[0074] In this embodiment, the first air inlet channel 6 delivers primary air to a designated location in the combustion chamber 3 through the first air supply port 8 to mix with the fuel gas. The second air inlet channel 7 delivers secondary air to a designated location in the combustion chamber 3 through the second air supply port 9 to provide oxygen for the combustion site. The connection portion 15 is fixedly disposed between the first air supply port 8 and the second air supply port 9, so that the distribution assembly 1 blocks the first air inlet channel 6 and the second air inlet channel 7, preventing the primary and secondary air from mixing and achieving high mixing accuracy.

[0075] This embodiment also provides a burner, including the above-mentioned distribution assembly 1, or including the above-mentioned combustion chamber box.

[0076] In this embodiment, the burner's second plate 12 is movably mounted on the first plate 11. As the first plate 11 rotates above the air inlet 2, the end of the second plate 12 away from the first plate 11 moves at the air inlet 2, thereby changing the area of the air inlets 2 on either side of the second plate 12, that is, changing the size of the first and second air inlets 2. The second plate 12 rotates with the first plate 11. As the angle between the second plate 12 and the plane containing the air inlet 2 gradually increases, the inner wall of the combustion chamber at the air inlet 2 exerts a force on the second plate 12 toward the first plate 11. At this point, the second plate 12 moves toward the first plate 11, shortening the distribution assembly 1. As the angle between the second plate 12 and the plane containing the air inlet 2 gradually decreases, the second plate 12 becomes suspended in the air. Under the action of gravity, the second plate 12 moves away from the first plate 11, lengthening the distribution assembly 1. With the above structure, when the first plate 11 rotates, one end of the distribution assembly 1 can always remain in contact with the air inlet 2, flexibly and accurately adjusting the ratio of primary air intake and secondary air intake, and the combustion efficiency of the burner is higher.
