Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a burner ignition device and a wall-hung boiler having the same. Background Technology

[0002] Burners are typically used to heat water; for example, in a wall-hung boiler, the burner heats the water in the boiler's tank. When the burner is working, gas enters and exits through the gas nozzle, where it is ignited by an electric spark from the ignition needle. If the ignition needle is too far from the gas nozzle, the spark may not effectively ignite the gas mixture, leading to delayed ignition or failure. Conversely, if the ignition needle is too close, the electrodes may be damaged by high-temperature erosion, or the spark may be scattered by the airflow. Furthermore, the ignition needle must be aligned with the flow path of the gas-air mixture; an improper tilt angle can cause the spark to deviate from the combustible zone. Currently, most burners have their ignition needles fixed inside the burner, making them difficult to disassemble and replace, and difficult to adjust, resulting in challenging ignition repairs.

[0033] The following is for reference. Figure 1 and Figure 2This invention describes a burner ignition device according to an embodiment of the present invention.

[0034] like Figure 1 and Figure 2 As shown, the burner ignition device according to an embodiment of the present invention includes a burner body 100, a front connecting frame 200, and an ignition needle assembly 300.

[0035] The burner body 100 includes a burner 110 and a front cover plate 140. A nozzle 132 is provided on the upper side of the burner 110, and the front cover plate 140 is located in front of the burner 110. A front connecting frame 200 is connected to the front side of the front cover plate 140. The front connecting frame 200 includes a connecting horizontal plate 210. A mounting ring 220 is provided on the connecting horizontal plate 210. The mounting ring 220 has a mounting hole 221, and the axis of the mounting hole 221 extends in the vertical direction. An ignition needle assembly 300 is inserted into the mounting hole 221. The ignition needle assembly 300 includes a conductive core 310 and an insulating sleeve 320. The conductive core 310 has a horizontal bend 311 on its upper side, which is located above the nozzle 132. The insulating sleeve 320 is located outside the conductive core 310. The insulating sleeve 320 is interference-fitted with the mounting ring 220. The ignition needle assembly 300 can move up and down along the mounting hole 221 to adjust its position.

[0036] For example, such as Figure 1 and Figure 2As shown, the burner body 100 includes a burner 110 and a front cover plate 140. The burner 110 is distributed within the burner body 100. A nozzle 132 is provided on the upper side of the burner 110, which is used to inject fuel to form a combustion flame. The front cover plate 140 is located in front of the burner 110, serving a protective and fixing function. A front connecting frame 200 is connected to the front of the front cover plate 140. Specifically, the front connecting frame 200 is fixed to the front cover plate 140 through a specific connection method to ensure the stability of the overall structure. The front connecting frame 200 includes a connecting cross plate 210, on which a mounting ring 220 is provided. The mounting ring 220 has a mounting hole 221, the axis of which extends vertically. An ignition needle assembly 300 is inserted into the mounting hole 221 to facilitate the installation and positioning of the ignition needle assembly 300. The ignition needle assembly 300 is securely installed in the mounting hole 221 via a plug-in connection, ensuring the accuracy and stability of the ignition process. The ignition needle assembly 300 includes a conductive core 310 and an insulating sleeve 320. The conductive core 310 has a horizontal bend 311 on its upper side, located above the nozzle 132. This bend ensures precise extension above the nozzle 132, facilitating accurate alignment with the fuel injection point during ignition. The insulating sleeve 320 is located outside the conductive core 310 and is connected to the mounting ring 220. The insulating sleeve 320, wrapping around the conductive core 310, provides insulation protection, while its tight connection with the mounting ring 220 ensures the stability and safety of the entire ignition needle assembly.

[0037] In actual operation, the burner body 100 sprays gas through the nozzle 132, and then the ignition needle assembly 300 is energized to generate a spark at the end of the horizontal bend 311. The spark ignites the gas sprayed from the nozzle 132, completing the ignition work and ensuring that the burner's combustion work proceeds normally.

[0038] The ignition needle assembly 300 is externally connected to the front side of the burner body 100 via the front connecting bracket 200, facilitating the disassembly, assembly, and adjustment of the ignition needle assembly 300. Since the horizontally bent portion 311 of the ignition needle assembly 300 extends horizontally above the nozzle 132, and the axis of the mounting hole 221 on the front connecting bracket 200 extends vertically, the ignition needle assembly 300 can be adjusted vertically along the mounting hole 221 to adjust the height of the horizontally bent portion 311. This ensures that the vertical distance between the horizontally bent portion 311 and the nozzle 132 is properly adjusted, guaranteeing that the burner of this invention can complete the ignition process normally and stably.

[0039] It must be noted that after the ignition needle assembly 300 is positioned correctly, the insulating sleeve 320 and the mounting ring 220 are connected by an interference fit. This means that the friction between the mounting ring 220 and the insulating sleeve 320 is sufficient to ensure a stable connection of the ignition needle assembly 300. The actual height adjustment range required for the ignition needle assembly 300 is not long, therefore it does not conflict with the connection of the insulating sleeve 320 and the mounting ring 220.

[0040] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4 The burner 110 includes a burner vertical fixing plate 120 and a gas chamber 130. The burner vertical fixing plate 120 is connected to the outer wall of the gas chamber 130. The gas chamber 130 has a burner air inlet 131 at the rear end and a nozzle 132 located on the upper side of the gas chamber 130. The gas chamber 130 has a gas chamber, and the two ends of the gas chamber are respectively connected to the burner air inlet 131 and the nozzle 132. The front connecting frame 200 is provided with a front connecting hole 142, and the front end of the burner vertical fixing plate 120 is inserted into the front connecting hole 142.

[0041] In the overall structure of the burner 110, the vertical fixing plate 120 serves as the support and fixation structure. The main function of the gas chamber 130 is to store and transport gas. Specifically, the rear end of the gas chamber 130 uses the burner air inlet 131 as an air inlet, allowing gas to smoothly enter the interior of the gas chamber 130. At the upper side of the gas chamber 130, nozzles 132 are distributed, which spray gas at appropriate pressure and flow rate to ensure combustion efficiency and stability.

[0042] The front connecting bracket 200 is provided with a front connecting hole 142, the size and position of which match the vertical fixing plate 120 of the burner. During actual installation, the front end of the vertical fixing plate 120 of the burner can be accurately inserted into the corresponding front connecting hole 142, thereby achieving a stable connection between the burner 110 and the front connecting bracket 200 and ensuring the stable operation of the entire burner.

[0043] In some embodiments of this utility model, the gas chamber 130 sequentially includes a lower gas chamber 134 on the lower side, a gas chamber transition position 135, and an upper gas chamber 133 on the upper side. That is, the lower gas chamber 134 and the upper gas chamber 133 are connected through the gas chamber transition position 135, and the lower gas chamber 134 and the upper gas chamber 133 form a "V" shape, making the structure of the gas chamber 130 more compact. The rear end of the lower gas chamber 134 is the burner inlet 131, while the nozzle 132 is distributed on the upper side of the upper gas chamber 133.

[0044] In some embodiments of this utility model, a front support plate 141 is provided on the lower side of the front cover plate 140, and a front connecting hole 142 is located on the front support plate 141. The lower front end of the vertical fixing plate 120 of the burner has a first insertion part 121, which is inserted into the front connecting hole 142. The front support plate 141 can support the lower front end of the burner 110, making the connection between each burner 110 and the front cover plate 140 more stable. The first insertion part 121 of the burner 110 is inserted into the corresponding front connecting hole 142 of the front cover plate 140, further ensuring that the burner 110 is sufficiently stable and reliable.

[0045] In some embodiments of this utility model, the burner body 100 further includes a rear cover plate 150, which is located behind the burner 110. The rear cover plate 150 is provided with a rear connection hole 151, and the rear end of the burner vertical fixing plate 120 has a second insertion part 122, which is inserted into the rear connection hole 151. The rear cover plate 150 is used to fix the rear end position of the burner 110. The second insertion part 122 at the rear end of the burner 110 is inserted into the corresponding rear connection hole 151 on the rear cover plate 150, making the connection between each burner 110 and the rear cover plate 150 more secure.

[0046] In some embodiments of this utility model, a third insertion part 123 is provided on the rear side of the vertical fixing plate 120 of the burner corresponding to the rear side of the upper gas chamber 133. A rear support plate 152 is provided on the upper side of the rear cover plate 150, and a rear limiting hole 153 is provided on the rear support plate 152. The third insertion part 123 is inserted into the rear limiting hole 153. The third insertion part 123 at the rear end of the burner 110 is inserted into the corresponding rear limiting hole 153 on the rear cover plate 150, which can specifically stabilize the rear end position of the upper gas chamber 133 of the gas chamber 130. This not only makes the connection between each burner 110 and the rear cover plate 150 more stable, but also ensures that the nozzle 132 on the upper gas chamber 133 ejects gas more reliably.

[0047] In some embodiments of this utility model, a gas distribution pipe 160 is provided on the rear side of the rear cover plate 150, a main air inlet pipe 161 is provided on the lower side of the gas distribution pipe 160, the main air inlet pipe 161 is connected to an external gas source, and a gas distribution nozzle 162 is provided on the front side of the gas distribution pipe 160. Each gas distribution nozzle 162 corresponds to the burner air inlet hole 131. The gas enters the gas chamber 130 through the main air inlet pipe 161, the gas distribution nozzle 162 and the burner air inlet hole 131 in sequence.

[0048] The primary function of the gas distribution pipe 160 is to evenly distribute gas. The main intake pipe 161 below the gas distribution pipe 160 connects to an external gas source, ensuring a stable gas supply. A series of gas distribution nozzles 162 arranged at the front of the gas distribution pipe 160 are required to precisely correspond to the burner inlet 131 of the burner 110, ensuring uniform gas distribution. In actual operation, the gas first enters the system through the main intake pipe 161, then, after precise distribution by the various gas distribution nozzles 162, smoothly enters the burner inlet 131, and further enters the gas chamber 130, completing the entire gas supply process. This ensures smooth gas flow and improves gas utilization efficiency and safety.

[0049] In some embodiments of this utility model, the air distribution pipe 160 is a horizontal pipe structure, and air distribution pipe connectors 163 are provided on both the left and right sides of the air distribution pipe 160. The air distribution pipe 160 is connected to the rear side of the rear cover plate 150 through the air distribution pipe connectors 163.

[0050] In some embodiments of this utility model, reference is made to Figure 5 The mounting ring 220 has an upper opening 222 and a lower opening 223. The ignition needle assembly 300 passes through the upper opening 222 and the lower opening 223 and is inserted into the mounting hole 221. The upper opening 222 is located above the connecting horizontal plate 210, and the lower opening 223 is connected to the connecting horizontal plate 210. This ensures that there is sufficient space around the mounting ring 220 to facilitate the insertion and installation of the ignition needle assembly 300.

[0051] In some embodiments of this invention, the mounting ring 220 has an elastic portion 224 on its upper side, and a partition groove 225 between adjacent elastic portions 224, allowing the elastic portions 224 to have space for elastic deformation. A fixing ring 250 is fitted onto the outer wall of the mounting ring 220. When the ignition needle assembly 300 is inserted into the mounting hole 221, the fixing ring 250 is fitted onto the mounting ring 220, ensuring that the elastic portion 224 can clamp the ignition needle assembly 300, making the ignition needle assembly 300 sufficiently stable. When it is necessary to adjust the height or angle of the ignition needle assembly 300, simply loosen the fixing ring 250.

[0052] In some embodiments of this utility model, the fixing ring 250 is a nut, and the inner wall of the fixing ring 250 is connected to the outer wall of the mounting ring 220 by a thread.

[0053] In some embodiments of this utility model, the inner wall of the fixing ring 250 is a circular hole structure, the outer wall of the mounting ring 220 is a cylindrical structure, and the inner wall of the fixing ring 250 and the outer wall of the mounting ring 220 are connected by a friction surface.

[0054] In some embodiments of this utility model, the insulating sleeve 320 is made of insulating ceramic fiber.

[0055] In some embodiments of this utility model, a vertical rib 321 is provided on the outer wall of the insulating sleeve 320, with the upper and lower ends of the vertical rib 321 extending to the upper and lower ends of the outer wall of the insulating sleeve 320. The vertical rib 321 can abut against the wall of the mounting hole 221, ensuring that the ignition needle assembly 300 is not easily loosened or shifted after being fixed.

[0056] In some embodiments of this utility model, the conductive core 310 has a power receiving end 312 on its lower side, and the power receiving end 312 is located below the connecting horizontal plate 210. The power receiving end 312 serves as the external power receiving position of the ignition needle assembly 300. The fact that the power receiving end 312 of the ignition needle assembly 300 is located below the connecting horizontal plate 210 facilitates wiring of the ignition needle assembly 300.

[0057] In some embodiments of this utility model, side guard plates 230 are provided on the left and right sides of the connecting horizontal plate 210, and a connecting vertical plate 240 is provided at the rear end of the side guard plate 230. The connecting vertical plate 240 is fixedly connected to the front cover plate 140 by screws 241, so that the front connecting frame 200 can be easily connected to the front cover plate 140. The side guard plates 230 on the left and right sides of the connecting horizontal plate 210 can improve the structural strength of the connecting horizontal plate 210 and also protect the ignition needle assembly 300.

[0059] In some embodiments of this utility model, the detection needle is horizontally bent at the detection end 410 and the detection needle is connected to the power supply end 420.

[0060] The wall-hung boiler according to a second aspect embodiment of the present invention includes a burner ignition device according to the first aspect embodiment of the present invention. After the wall-hung boiler is powered on, the burner in this embodiment turns on, and gas is ejected through the nozzle 132. Simultaneously, the ignition needle assembly 300 generates a high-frequency electric spark to ignite the gas. In this embodiment, the burner heats the water, and the heat exchanger absorbs the heat to heat the flowing heating water to a set temperature. This can both promote the circulation of heating water through the underfloor heating / radiator system and heat domestic water.

[0061] According to the wall-hung boiler of this utility model embodiment, by adopting the above-mentioned burner ignition device, the ignition needle assembly 300 can be adjusted in height by moving up and down to ensure that the vertical distance between the horizontal bending part 311 and the nozzle 132 is properly adjusted, so as to ensure that the wall-hung boiler of this utility model can complete the ignition work normally and stably.
