Description

Technical Field

[0001] The present invention relates to the field of burners, and more specifically, to a burner and a wall-mounted boiler with uniform segmented combustion. Background Art

[0002] The full name of a wall-mounted boiler is: "Gas wall-mounted heating boiler". It and a gas instantaneous water heater are both fast heating devices without a hot water storage device, but there are essential differences in structure. In the wall-mounted boiler, heating is carried out by a burner. The burner mixes air and fuel in an appropriate proportion through a premixing device to make it burn fully.

[0003] Chinese Patent with the authorization announcement number CN108916872B for a gas water heater and its burner discloses that by providing at least two non-communicating gas mixing channels in the burner and correspondingly providing at least two relatively independent ejector holes, the gas ejecting air capacity is increased, so that the gas burns more fully, and the emissions of NOX and CO during the combustion process can be reduced.

[0004] Although the above patent solves the problem of reducing the emissions of NOX and CO during the combustion process, when the combustion is insufficient, it is easy to cause carbon deposition on the surface of the heat conduction fins. These carbon deposits are easy to fall into the spray holes in the water heater, which is easy to cause blockage, resulting in poor combustion effect in the burner and poor water heating effect. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a burner and a wall-mounted boiler with uniform segmented combustion. By rotating two baffles, the two baffles block the top of the combustion part, thereby preventing the carbon deposits in the heat exchange part from falling onto the surface of the combustion part and causing blockage of the spray holes on the surface of the combustion part. When the combustion part is heated, the baffle is driven to rotate by a driving part. After the baffle rotates, it will no longer block the combustion part, so that the combustion part ejects gas and ignites the gas, and the burning gas heats the heat exchange part. At this time, the gas ejected by the combustion part will not cause blockage of the spray holes of the combustion part.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A burner with uniform segmented combustion includes a housing. A combustion mechanism is arranged inside the housing. The combustion mechanism is used for heating water and conveying it. The combustion mechanism includes a protective shell fixed inside the housing. A combustion part is fixedly connected to the bottom of the protective shell. A heat exchange part is fixedly connected to the top of the protective shell. A blocking mechanism is arranged at the top of the combustion part;

[0008] The blocking mechanism includes mounting plates fixed on both sides of the top of the combustion part. A baffle is rotatably connected to the top of the mounting plate. A driving part is fixedly connected to the bottom of the mounting plate close to the baffle.

[0009] Further, the driving member includes a fixing column fixed to the mounting plate. A moving column is slidably connected inside the fixing column, and water is injected into the bottom inside the fixing column.

[0010] Further, the fixing column is made of copper. Triangular blocks are fixedly connected to both the front and rear sides of the top of the mounting plate, and a blocking ring is fixedly connected to the top of the fixing column.

[0011] Further, a first heat-conducting fin is fixedly connected inside the heat-exchanging member. A cleaning mechanism is arranged inside the first heat-conducting fin. The cleaning mechanism includes a connecting block. A plurality of second heat-conducting fins distributed at equal intervals are fixedly connected to the top of the connecting block. When the connecting block moves, it can control the second heat-conducting fins to move upward.

[0012] Further, through grooves corresponding to water pipes are formed inside the second heat-conducting fins. Third heat-conducting fins are fixedly connected to both side surfaces of the second heat-conducting fins. The third heat-conducting fins are attached to the adjacent first heat-conducting fins, and the cross-sectional shape of the third heat-conducting fins is an inverted V shape.

[0013] Further, collecting boxes are arranged on both sides of the combustion member. A rotating plate is rotatably connected to the inner top of the collecting box. A blocking plate is fixedly connected to one side of the top of the collecting box away from the baffle plate, and the blocking plate is attached to the rotating plate.

[0014] Further, a pressing member is slidably connected to one side of the mounting plate close to the collecting box. A pressing block is fixedly connected to one side of the baffle plate close to the pressing member. An extension block is formed by extending the top of the pressing member, and a rotating block is rotatably connected to the middle of the extension block.

[0015] Further, a blocking block is formed by extending one side of the extension block close to the pressing block. A first slider is formed by extending one side of the pressing member close to the mounting plate, and a first sliding groove is formed inside the mounting plate.

[0016] Further, the bottom of the pressing member contacts the rotating plate. A spring piece is fixedly connected to the top of one side of the rotating plate close to the pressing member, and the value of the gravity of the pressing member is the same as the elastic force of the spring piece.

[0017] A wall-mounted boiler includes the burner with uniform segmented combustion described above.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this solution, by rotating two baffles, the tops of the combustion components are blocked by the two baffles, thus preventing the carbon deposits in the heat exchange component from falling onto the surface of the combustion component and blocking the gas injection holes on the surface of the combustion component. When the combustion component is heated, the baffles are rotated by a driving component. After the baffles are rotated, they no longer block the combustion component, allowing the combustion component to eject gas and ignite the gas. The burning gas heats the heat exchange component. At this time, the gas ejected by the combustion component will not cause the gas injection holes of the combustion component to be blocked. By driving the baffles back to their original positions through the driving component, it effectively prevents the carbon deposits in the heat exchange component from falling on the tops of the baffles when the device is not in use, and will not cause the carbon deposits to block the gas injection holes in the combustion component, resulting in better use effects. Moreover, when the combustion component burns again, the baffles rotate again. At this time, the carbon deposits on the surface of the baffles slide off the surface of the baffles to both sides of the combustion component, making it more convenient to recycle the carbon deposits.

[0020] 2. In this solution, through the combustion of the combustion component, the water inside the fixed column is heated and transformed into a gaseous state. By controlling the amount of water in the fixed column, the extrusion of the moving column by the water in the fixed column after it turns into a gaseous state can be controlled, thereby controlling the movement and the amount of movement of the moving column. When the combustion component is turned off, after the water in the fixed column cools down and turns into a liquid, the moving column can return to its original position, and the moving column no longer presses on the baffle, allowing the baffle to return to its original position due to gravity. After the baffle rotates, it is blocked by the triangular block, making the rotation angle of the baffle less than ninety degrees. After the moving column returns to its original position, it is more convenient for the baffle to return to its original position.

[0021] 3. In this solution, after the combustion component burns for a period of time, when the combustion is incomplete, some carbon deposits are likely to remain on the surface of the first heat conduction fin. The connecting block drives the second heat conduction fin and the third heat conduction fin to move downward. At this time, the third heat conduction fin scrapes the surface of the first heat conduction fin, facilitating the scraping off of the carbon deposits on the edge of the first heat conduction fin, and making it more convenient to clean the carbon deposits on the surface of the first heat conduction fin. The cross-sectional shape of the third heat conduction fin is an inverted V shape, facilitating the carbon deposits scraped off to move downward along the third heat conduction fin, preventing the carbon deposits from remaining inside the cleaning mechanism. The carbon deposits fall on the surface of the baffle, making it more convenient to handle the carbon deposits. And each time the combustion of the combustion component ends, the carbon deposits can be processed, preventing the carbon deposits from staying on the surface of the first heat conduction fin for a long time, and when the device is in an oil and gas environment for a long time, causing the carbon deposits to adhere to the surface of the first heat conduction fin, making it more difficult to handle the carbon deposits, and making the device more convenient to use.

[0022] 4. In this solution, by rotating the rotating plate, the side of the rotating plate close to the baffle is lifted, creating a gap between the blocking plate and the rotating plate. At this time, the rotating plate tilts towards the blocking plate, facilitating the guiding of the carbon deposits on the surface of the rotating plate, causing the carbon deposits on the surface of the rotating plate to enter the gap between the blocking plate and the rotating plate, and the carbon deposits enter the interior of the collection box, making it more convenient to collect the carbon deposits and preventing the already collected carbon deposits from being affected when gas and air are introduced into the device.

[0023] 5. In this solution, the extrusion block rotates to extrude the rotating block, causing the rotating block to rotate. At this time, the extrusion block passes through the rotating block and continues to rotate. When the combustion part does not burn and the baffle returns to its original position, after the extrusion part moves upward, the extrusion part no longer restricts the rotating plate. The numerical value of the gravity of the extrusion part is the same as the elastic force of the elastic piece. When the extrusion part moves, the elastic piece extrudes the rotating plate, causing the rotating plate to be extruded and rotate. At this time, the rotation of the rotating plate is more convenient, and the rotation occurs at the moment when the baffle closes. At this time, no gas and air are introduced into the device. At this time, it is convenient for the rotating plate to rotate and the carbon deposits to enter the inside of the collection box, making the collection of carbon deposits more convenient.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 10, a burner with uniform segmented combustion, comprising a housing 1, a blower for sucking air is installed through the top of the housing 1, a combustion mechanism 2 is arranged inside the housing 1, and the combustion mechanism 2 is used for heating and conveying water. The combustion mechanism 2 includes a protective shell 23 fixed inside the housing 1. A combustion element 21 is fixedly connected to the bottom of the protective shell 23, and the combustion element 21 heats the inside of the protective shell 23. A heat exchange element 22 is fixedly connected to the top of the protective shell 23. A water pipe passes through the heat exchange element 22. Gas is ejected through the combustion element 21, and these gases are ignited to heat the heat exchange element 22. Through the heat conductivity of the heat exchange element 22, heat is transferred from the heat exchange element 22 to the pipe inside the heat exchange element 22, achieving the heating of the water in the pipe of the heat exchange element 22. A blocking mechanism 3 is arranged at the top of the combustion element 21. The blocking mechanism 3 includes mounting plates 32 fixed on both sides of the top of the combustion element 21. A baffle 31 is rotatably connected to the top of the mounting plate 32. By rotating the two baffles 31, the top of the combustion element 21 is blocked by the two baffles 31, thereby preventing the carbon deposits in the heat exchange element 22 from falling onto the surface of the combustion element 21 and causing the air holes on the surface of the combustion element 21 to be blocked. A driving member 35 is fixedly connected to the bottom of one side of the mounting plate 32 close to the baffle 31. When the combustion element 21 is heated, the baffle 31 is driven to rotate by the driving member 35. After the baffle 31 rotates, it will no longer block the combustion element 21, enabling the combustion element 21 to eject gas and ignite the gas. The burning gas heats the heat exchange element 22. At this time, the gas ejected by the combustion element 21 will not cause the air holes of the combustion element 21 to be blocked. When the heating of the combustion element 21 ends, the baffle 31 is driven back to its original position by the driving member 35, effectively preventing the carbon deposits in the heat exchange element 22 from falling on the top of the baffle 31 when the device is not in use and not causing the air holes in the combustion element 21 to be blocked by carbon deposits, with better use effects. And when the combustion element 21 burns again, the baffle 31 rotates again. At this time, the carbon deposits on the surface of the baffle 31 slide off the surface of the baffle 31 to both sides of the combustion element 21, making the recovery of carbon deposits more convenient.

[0038] Such as Figures 1 to 10As shown, the driving member 35 includes a fixed column 351 fixed to the mounting plate 32. A moving column 353 is slidably connected inside the fixed column 351, making it more convenient for the moving column 353 to move inside the fixed column 351. When the moving column 353 moves inside the fixed column 351, the top of the moving column 353 can squeeze the baffle 31, causing the baffle 31 to rotate around the mounting plate 32, making it more convenient for the baffle 31 to rotate. Water is injected into the bottom inside the fixed column 351. Through the combustion of the combustion member 21, the water inside the fixed column 351 is heated and transformed into a gaseous state. By controlling the amount of water inside the fixed column 351, it is possible to control the extrusion of the moving column 353 by the water in the fixed column 351 after it turns into a gaseous state, thereby controlling the movement and the amount of movement of the moving column 353. The material of the fixed column 351 is copper, which heats the water in the fixed column 351 faster, making it more convenient for the baffle 31 to open. And when the combustion member 21 is turned off, after the water in the fixed column 351 cools and turns into a liquid, the moving column 353 can return to its original position, and the moving column 353 no longer squeezes the baffle 31, enabling the baffle 31 to return to its original position due to gravity. Triangular blocks 321 are fixedly connected to both the front and rear sides of the top of the mounting plate 32. After the baffle 31 rotates, it is blocked by the triangular blocks 321, making the rotation angle of the baffle 31 less than 90 degrees. And after the moving column 353 returns to its original position, it is more convenient for the baffle 31 to return to its original position. A blocking ring 352 is fixedly connected to the top of the fixed column 351. The moving column 353 is restricted by the blocking ring 352 to prevent the moving column 353 from detaching from the fixed column 351.

[0039] As Figures 1 to 10As shown, a first heat-conducting fin 221 is fixedly connected inside the heat exchange member 22, and a cleaning mechanism 4 is arranged inside the first heat-conducting fin 221. The cleaning mechanism 4 includes a connecting block 41. When the combustion member 21 burns and drives the baffle 31 to rotate, the rotation of the baffle 31 can squeeze the connecting block 41, making it more convenient for the connecting block 41 to move. A plurality of second heat-conducting fins 42 are fixedly connected to the top of the connecting block 41 and are evenly distributed at equal intervals. The movement of the connecting block 41 can control the upward movement of the second heat-conducting fins 42, making it more convenient for the second heat-conducting fins 42 to move. A through groove 44 corresponding to the water pipe is opened inside the second heat-conducting fin 42, making it more convenient for the connecting block 41 and the second heat-conducting fins 42 to move without being blocked by the water pipe. And the water pipe passes through the through groove 44 to realize the fixation between the water pipe and the cleaning mechanism 4. Third heat-conducting fins 43 are fixedly connected to both side surfaces of the second heat-conducting fin 42, and the third heat-conducting fins 43 are attached to the adjacent first heat-conducting fins 221. After the combustion member 21 burns, the rotation of the baffle 31 drives the second heat-conducting fins 42 to move upward with the third heat-conducting fins 43. At this time, there is no carbon deposit on the surface of the first heat-conducting fin 221. When the combustion member 21 burns for a period of time and then is turned off, the baffle 31 returns to its original position. At this time, the baffle 31 no longer squeezes the connecting block 41, causing the connecting block 41 and the second heat-conducting fins 42 to move downward due to gravity. Since the combustion member 21 burns for a period of time, when the combustion member 21 burns insufficiently, some carbon deposits are likely to remain on the surface of the first heat-conducting fin 221. The connecting block 41 drives the second heat-conducting fins 42 and the third heat-conducting fins 43 to move downward. At this time, the third heat-conducting fins 43 scrape the surface of the first heat-conducting fin 221, facilitating the scraping off of the carbon deposits on the first heat-conducting fin 221 and making it more convenient to clean the carbon deposits on the surface of the first heat-conducting fin 221. The cross-sectional shape of the third heat-conducting fin 43 is an inverted V shape, facilitating the carbon deposits scraped off to move downward along the third heat-conducting fin 43 and preventing the carbon deposits from remaining inside the cleaning mechanism 4. The carbon deposits fall on the surface of the baffle 31, making it more convenient to handle the carbon deposits. And each time the combustion member 21 burns out, the carbon deposits can be processed, preventing the carbon deposits from staying on the surface of the first heat-conducting fin 221 for a long time. And when the device is in an oil and gas environment for a long time, it will cause the carbon deposits to adhere to the surface of the first heat-conducting fin 221, making it more difficult to handle the carbon deposits and making the device more convenient to use. And the second heat-conducting fins 42 and the third heat-conducting fins 43 are in contact with the heat exchange member 22. The second heat-conducting fins 42 and the third heat-conducting fins 43 are made of copper, making the heat exchange effect better.

[0040] As Figures 1 to 10As shown, collection boxes 33 are provided on both sides of the combustion part 21. By rotating the baffle 31, the carbon deposits on the surface area of the baffle 31 can be moved towards the collection box 33. A rotating plate 331 is rotatably connected to the inner top of the collection box 33, which facilitates the carbon deposits to stay on the top of the rotating plate 331. A blocking plate 332 is fixedly connected to one side of the top of the collection box 33 away from the baffle 31, and the blocking plate 332 is in contact with the rotating plate 331. By rotating the rotating plate 331, the side of the rotating plate 331 close to the baffle 31 is lifted, creating a gap between the blocking plate 332 and the rotating plate 331. At this time, the rotating plate 331 is inclined towards the blocking plate 332, facilitating the guiding of the carbon deposits on the surface of the rotating plate 331, so that the carbon deposits on the surface of the rotating plate 331 enter the gap between the blocking plate 332 and the rotating plate 331, and the carbon deposits enter the interior of the collection box 33, making the collection of carbon deposits more convenient and preventing the carbon deposits that have been collected from being affected when gas and air are introduced into the device.

[0041] As Figures 1 to 10 shown, a pressing part 34 is slidably connected to one side of the mounting plate 32 close to the collection box 33, and a pressing block 311 is fixedly connected to one side of the baffle 31 close to the pressing part 34. When the baffle 31 rotates due to the combustion of the combustion part 21, the rotation of the baffle 31 can control the rotation of the pressing block 311. An extension block 342 is formed by extending the top of the pressing part 34, and a rotating block 343 is rotatably connected to the middle of the extension block 342. By rotating the pressing block 311 to press the rotating block 343, the rotating block 343 rotates. At this time, the pressing block 311 passes through the rotating block 343 and continues to rotate. When the combustion part 21 does not burn and the baffle 31 returns to its original position, the pressing block 311 presses the rotating block 343 again. A blocking block 344 is formed by extending the side of the extension block 342 close to the pressing block 311. By blocking the rotation of the rotating block 343 with the blocking block 344, the pressing block 311 presses the rotating block 343, causing the rotating block 343 to drive the extension block 342 to move upward. A first slider 341 is formed by extending the side of the pressing part 34 close to the mounting plate 32, and a first sliding groove 322 is opened inside the mounting plate 32. At this time, the first slider 341 moves inside the first sliding groove 322, making the movement of the pressing part 34 more stable. The bottom of the pressing part 34 is in contact with the rotating plate 331. When the pressing part 34 moves upward, the pressing part 34 no longer restricts the rotating plate 331. A elastic piece 333 is fixedly connected to the top of the side of the rotating plate 331 close to the pressing part 34. The numerical value of the gravity of the pressing part 34 is the same as the elastic force of the elastic piece 333. When the pressing part 34 moves, the elastic piece 333 presses the rotating plate 331, causing the rotating plate 331 to be pressed and rotate. At this time, the rotation of the rotating plate 331 is more convenient, and the rotation occurs at the moment when the baffle 31 is closed. At this time, gas and air are not introduced into the device, and at this time, the rotation of the rotating plate 331 facilitates the entry of carbon deposits into the interior of the collection box 33, making the collection of carbon deposits more convenient.
