Description

Technical Field

[0001] This utility model belongs to the field of burner technology, and in particular relates to a burner with condensation atomization function, a gas water heater and a gas heating boiler. Background Technology

[0002] Currently, the burner is an important component in gas water heaters or gas boilers. The burner heats the water flowing through the main heat exchange tube by burning gas to generate high-temperature flue gas. The flue gas after heat exchange will be discharged from the exhaust pipe.

[0003] In existing technologies, to fully utilize the heat of flue gas, a condenser heat exchanger tube is installed on the burner. The flue gas supplied by the burner to the exhaust pipe first exchanges heat with the condenser heat exchanger tube before being discharged from the exhaust pipe. However, during use, condensate will form on the surface of the condenser heat exchanger tube due to condensation. This condensate contains acidic substances due to contact with the flue gas and needs to be collected and treated promptly. Conventional technologies typically collect the condensate in a water collection tank and then atomize it through an atomizer. However, during use, as the usage time increases, insufficiently atomized condensate will gradually accumulate in the atomizer, easily causing overflow. This overflowing condensate can damage the internal electrical components of the equipment, and it can also pollute the indoor environment, leading to reduced reliability and a poor user experience.

[0004] Therefore, the technical problem to be solved by this invention is how to design a technology to reduce condensate overflow in order to improve reliability and user experience. Utility Model Content

[0005] This invention provides a burner, gas water heater, and gas boiler with condensation atomization function, which reduces condensate overflow to improve reliability and user experience.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0073] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0074] like Figure 1 As shown, one embodiment of this application provides a burner, including:

[0075] Combustion chamber 1, on which a main heat exchange tube 11 is provided, and a smoke collection hood 12 is provided on the top of the combustion chamber 1, and a smoke exhaust port is provided on the smoke collection hood 12;

[0076] The condensing assembly 2 includes a housing 21 and a condensing heat exchange tube 22. The housing 21 is provided with an air inlet 211, an air outlet 212 and a drain hole 213. The condensing heat exchange tube 22 is disposed in the housing 21 and is connected to the main heat exchange tube 11.

[0077] Fan 13, the air inlet of the fan 13 is connected to the smoke exhaust port, and the air outlet of the fan 13 is connected to the air inlet connection port 211;

[0078] A water storage container 4 is provided with a pumping pipe 43, a diversion pipe 45, and a return pipe 47. The water storage container 4 is provided with a water storage area 401, a water seal area 402, and a return area 403. The water storage area 401 is connected to the water seal area 402 and the return area 403 respectively. The pumping pipe 43 extends into the water storage area 401, the diversion pipe 45 extends into the water seal area 402, and the return pipe 47 extends into the return area 403. The diversion pipe 45 is connected to the drain hole 213.

[0079] Atomizing device 3 is provided with an air inlet 313, an exhaust outlet 311, a water return outlet 314, and a water supply pipe 312. The atomizing device 3 is configured to atomize the condensate input into the water supply pipe 312 to form mist, and the mist is output from the exhaust outlet 311 along with the flue gas input into the air inlet 313. The water return outlet 314 is configured to output the un-atomized condensate in the atomizing device 3. The air inlet 313 is connected to the air outlet connection 212, and the water return outlet 314 is connected to the water return pipe 47.

[0080] Water pump 41, the inlet of which is connected to the pumping pipe 43, and the outlet of which is connected to the water delivery pipe 312.

[0081] Specifically, combustion chamber 1 is equipped with components such as a burner to meet the requirements for combustion of gas within combustion chamber 1. The specific structure of combustion chamber 1 can be referenced from the existing combustion chamber 1 structures in gas water heaters and gas boilers in the prior art, and is not limited here. A fan 13 is installed on the top of combustion chamber 1, and combustion chamber 1 is connected to the air inlet 211 of condensing component 2 through fan 13. The air outlet 212 of condensing component 2 is connected to the air inlet 313 of atomizing device 3.

[0082] The drain hole 213 of the condenser assembly 2 is connected to the drain pipe 45. The condensate generated by the condenser assembly 2 is output from the drain hole 213 and transported to the water seal zone 402 of the water storage container 4 via the drain pipe 45. After the condensate in the water seal zone 402 flows out, it flows into the water storage zone 401. The condensate in the water storage zone 401 is transported to the atomizing device 3 by the water pump 41 for atomization. The condensate that is not atomized in the atomizing device 3 collects at the bottom and is output from the return port 314. The condensate output from the return port 314 is transported to the return zone 403 of the water storage container 4 via the return pipe 47. After the condensate in the return zone 403 flows out, it flows back into the water storage zone 401.

[0083] Since condensate is generated in the condensation component 2, and flue gas is also transported in the space where condensate is generated in the condensation component 2, in order to reduce the amount of flue gas entering the water storage container 4, a relatively independent water storage area 401, a water seal area 402, and a return flow area 403 are formed in the water storage container 4.

[0084] The condensate generated in the condenser assembly 2 flows out of the drain hole 213 and then into the water seal zone 402 via the drain pipe 45. The volume of the water seal zone 402 is smaller than that of the water storage zone 401, allowing the condensate level to rise rapidly in the water storage zone 401 and submerge the drain pipe 45. The condensate in the water seal zone 402 acts as a water seal for the drain pipe 45, preventing flue gas from the condenser assembly 2 from continuously entering the water storage container 4. As the water level in the water seal zone 402 continues to rise, the condensate overflows from the water seal zone 402 into the water storage zone 401. The water storage zone 401 has a larger volume, sufficient to meet the storage requirements of the condensate generated by the condenser assembly 2.

[0085] Similarly, the un-atomized condensate from the atomizing device 3 flows out of the return port 314 and into the return zone 403 via the return pipe 47. The volume of the return zone 403 is smaller than that of the storage zone 401, allowing the condensate level to rise rapidly in the return zone 403 and submerge the return pipe 47. The condensate in the return zone 403 then acts as a water seal on the return pipe 47, preventing the flue gas from the atomizing device 3 from entering the storage container 4. As the water level in the return zone 403 continues to rise, the condensate overflows from the return zone 403 into the storage zone 401.

[0086] By providing a return water inlet 314 on the atomizing device 3, it can be ensured that excessive condensate will not accumulate inside the atomizing device 3, thus preventing overflow. In addition, the condensate generated by the condensing component 2 and the condensate output from the atomizing device 3 are respectively delivered to the water seal area 402 and the return area 403 in the water storage container 4, and the condensate output from the condensing component 2 and the condensate returned from the atomizing device 3 do not affect each other.

[0087] In one embodiment, the water storage container 4 includes a water storage box 48 and a box cover 44. The water storage box 48 forms the water storage area 401, the water seal area 402 and the return area 403. The box cover 44 is provided with the water pumping pipe 43, the drain pipe 45 and the return pipe 47. The box cover 44 is detachably mounted on the water storage box 48.

[0088] Specifically, the water storage container 4 includes a water storage box 48 and a box cover 44. The box cover 44 can be removed from the water storage box 48 to meet the requirements of later maintenance.

[0089] In one embodiment, a partition 481 is provided in the water storage box 48, the partition 481 extends vertically upward from the bottom surface of the water storage box 48, and the water storage box 48 forms the water storage area 401 on one side of the partition 481;

[0090] The water storage box 48 is also provided with a first interval 482 and a second interval 483, which are arranged on the other side of the partition 481.

[0091] The first partition 482 forms the water seal area 402 in the water storage box 48, and the second partition 483 forms the reflux area 403 in the water storage box 48;

[0092] The upper part of the partition 481 is provided with a first connecting hole 4811 and a second connecting hole 4812. The first connecting hole 4811 is configured to connect the water storage area 401 and the water seal area 402, and the second connecting hole 4812 is configured to connect the water storage area 401 and the return flow area 403.

[0093] Specifically, the partition 481 in the water storage box 48 separates the water storage area 401 from the water seal area 402 and the return area 403. After the condensate in the water seal area 402 flows out, it flows into the water storage area 401 through the first connecting hole 4811. Similarly, after the condensate in the return area 403 flows out, it flows into the water storage area 401 through the second connecting hole 4812.

[0094] Furthermore, a first water outlet 4821 is provided at the bottom of the first interval portion 482, and the first water outlet 4821 is higher than the lower opening of the drainage pipe 45.

[0095] Specifically, the condensate in the water seal zone 402 will flow out from the first water outlet 4821 at the bottom, and the height of the lower pipe opening of the drain pipe 45 is lower than the height of the first water outlet 4821, so as to ensure that the water level in the water seal zone 402 is kept above the lower pipe opening of the drain pipe 45 to form an effective water seal.

[0096] Furthermore, a second water flow hole 4831 is provided at the bottom of the second interval 483, and the second water flow hole 4831 is higher than the lower pipe opening of the return water pipe 47.

[0097] Specifically, the condensate in the return zone 403 will flow out from the second water outlet 4831 at the bottom, and the height of the lower pipe opening of the return pipe 47 is lower than the height of the second water outlet 4831, so as to ensure that the water level in the return zone 403 is kept above the lower pipe opening of the return pipe 47 to form an effective water seal.

[0098] In one embodiment, a first filler area 404 is formed in the water storage box 48 between the first spacer 482 and the partition 481;

[0099] The first packing zone 404 is filled with neutralizing packing material, which is configured to neutralize acidic substances.

[0100] Specifically, the condensate in the water seal zone 402 first flows into the first packing zone 404, and after being treated by the neutralizing packing, it overflows into the water storage zone 401. The neutralizing packing can be a granular filter element containing magnesium oxide; there are no restrictions on its use.

[0101] Furthermore, a second filler area 405 is formed in the water storage box 48 between the second spacer 483 and the partition 481;

[0102] The neutralizing filler is also filled in the second filler zone 405.

[0103] Specifically, since the condensate in the atomizing device 3 may become weakly acidic after contact with the flue gas, the condensate flowing out of the return zone 403 is also treated by the neutralizing packing. The condensate in the return zone 403 first flows into the second packing zone 405, and after being treated by the neutralizing packing, it overflows into the water storage zone 401.

[0104] A partition 489 is provided between the first packing area 404 and the second packing area 405. The partition 489 separates the first packing area 404 and the second packing area 405.

[0105] In one embodiment, the water storage container 4 further includes a cover plate 484, which is disposed in the water storage box 48 and covers the first filling area 404 and the second filling area 405.

[0106] Specifically, to prevent the neutralizing filler from leaking out of the first filler area 404 and the second filler area 405 during transportation, a cover plate 484 is provided in the water storage box 48 to cover the neutralizing filler located in the first filler area 404 and the second filler area 405, thereby improving the reliability of use.

[0107] Furthermore, the partition 481 is provided with a first slot 4813, the side wall of the water storage box 48 is provided with a second slot 485, and the edge of the cover plate 484 is provided with a first protrusion 4841 and a second protrusion 4842. The first protrusion 4841 is engaged in the first slot 4813, and the second protrusion 4842 is engaged in the second slot 485.

[0108] Specifically, to facilitate the assembly of the cover plate 484, the cover plate 484 can be assembled into the water storage box 48 using a snap-fit ​​method. When assembling the cover plate 484, the first protrusion 4841 on the edge of the cover plate 484 snaps into the first slot 4813, and the second protrusion 4842 snaps into the second slot 485, so that the cover plate 484 is snapped into the water storage box 48.

[0109] In one embodiment, the bottom of the water storage box 48 is provided with a first drain outlet, which is connected to the water storage area 401, and a removable first plug 486 is provided on the first drain outlet.

[0110] Specifically, when it is necessary to clean the water storage area 401 of the water storage box 48, the first plug 486 can be removed, and the dirt at the bottom of the water storage area 401 will be discharged from the first drain port. The first plug 486 can be installed on the first drain port by means of a threaded connection.

[0111] In one embodiment, a second drain outlet is provided at the bottom of the water storage box 48, the second drain outlet is connected to the water seal area 402, and a detachable second plug 487 is provided on the second drain outlet.

[0112] Specifically, when it is necessary to clean the water seal area 402 of the water storage box 48, the second plug 487 can be removed, and the dirt at the bottom of the water seal area 402 will be discharged from the second drain port. The second plug 487 can be installed on the second drain port by means of a threaded connection.

[0113] In one embodiment, a third drain outlet is provided at the bottom of the water storage box 48, the third drain outlet is connected to the return flow area 403, and a detachable third plug 488 is provided on the third drain outlet.

[0114] Specifically, when it is necessary to clean the return flow area 403 of the water storage box 48, the third plug 488 can be removed, and the dirt at the bottom of the return flow area 403 will be discharged from the third drain port. The third plug 488 can be installed on the third drain port by means of a threaded connection.

[0115] In one embodiment, a water level detection element 42 is provided on the cover 44. The water level detection element 42 extends into the water storage box 48 and is located in the water storage area 401. The water level detection element 42 is configured to detect the water level in the water storage area 401 of the water storage container 4.

[0116] Specifically, by adding a water level detection element 42 to the water storage container 4, the water level detection element 42 can detect the amount of condensate stored in the water storage container 4. When the water level is higher than the preset low water level value, the water level detection element 42 will trigger the water pump 41 to start to pump the condensate to the atomizing device 3 for atomization treatment. When the water level is lower than the preset value, the water pump 41 will stop running.

[0117] In some embodiments, the physical manifestation of the water level detection element 42 can take various forms. For example, the water level detection element 42 may include multiple liquid level sensors, which are sequentially distributed along the height direction of the water storage container 4. Alternatively, the water level detection element 42 may be a float switch.

[0118] In one embodiment of this application, to facilitate assembly and improve assembly efficiency, a fan 13 is mounted on the top of the combustion chamber 1. The combustion chamber 1 is connected to the housing 21 of the condensing component 2 via the fan 13. A water storage container 4 and an atomizing device 3 are also provided on the housing 21 of the condensing component 2, and a water pump 41 is integrated and mounted on the water storage container 4. Thus, the condensing component 2, fan 13, water storage container 4, water pump 41, and atomizing device 3 are all integrated into the combustion chamber 1 and the housing 21 of the condensing component 2 to form a single integrated structure. When the burner is assembled onto the housing of a gas water heater or gas boiler, it can be directly fixed to the housing using the first mounting part 10 and the second mounting part 30 to meet assembly requirements.

[0119] Furthermore, the housing 21 is provided with a third mounting part 23 for fixing the condenser assembly 2.

[0120] Specifically, in order to improve the overall installation reliability of the burner, a third mounting part 23 can be further provided on the housing 21 of the condensing component 2, and the housing 21 can be further fixedly connected to the machine casing through the third mounting part 23.

[0121] And / or, the water storage container 4 is provided with a fourth mounting part 46 for fixing the water storage container 4.

[0122] Specifically, in order to improve the overall installation reliability of the burner, a fourth mounting part 46 can be further provided on the water storage container 4, and the water storage container 4 can be further fixedly connected to the casing through the fourth mounting part 46.

[0123] In one embodiment, the first mounting part 10, the second mounting part 30, the third mounting part 23 and / or the fourth mounting part 46 can be fixedly connected to the housing by conventional connectors such as screws or bolts, which will not be described in detail here.

[0124] In one embodiment of this application, the water storage container 4 is provided with a detachable shock-absorbing bracket 411, and the water pump 41 is mounted on the shock-absorbing bracket 411.

[0125] Specifically, since the water pump 41 is prone to noise due to vibration during operation, a shock-absorbing bracket 411 is provided on the water storage container 4 to reduce the vibration impact of the water pump 41 during operation.

[0126] The shock absorber bracket 411 can be made of elastic materials, such as rubber or silicone, which will not be elaborated here.

[0127] In one embodiment, the specific structure of the first mounting part 10, the second mounting part 30, the third mounting part 23 and / or the fourth mounting part 46 can be bolt holes or screw holes, and they are fixedly connected to the housing by conventional connectors such as screws or bolts, which will not be described in detail here.

[0128] In one embodiment of this application, as Figure 1 , Figures 6 to 11 As shown, to improve the atomization effect of condensate, the atomizing device 3 includes an atomizing shell 31, a centrifugal rotating component 32, and a drive motor 33. The atomizing shell 31 is also provided with an exhaust port 311 and a water return port 314 at the bottom. The atomizing shell 31 is also provided with a water supply pipe 312. The centrifugal rotating component 32 is rotatably disposed in the atomizing shell 31 and is arranged below the water outlet of the water supply pipe 312. The water supply pipe 312 is configured to transport the condensate output from the drain hole 213 to the centrifugal rotating component 32. A water storage area is formed on the upper surface of the centrifugal rotating component 32. The centrifugal rotating component 32 is configured to rotate and throw out the condensate in the water storage area to form mist and discharge it from the exhaust port 311. The drive motor 33 is connected to the centrifugal rotating component 32.

[0129] Specifically, the condensate flows through the water supply pipe 312 to the centrifugal rotating component 32. Driven by the drive motor 33, the centrifugal rotating component 32 rotates, causing the condensate on it to rotate along with the centrifugal rotating component 32.

[0130] As the condensed water rotates on the centrifugal rotating component 32, it is rapidly thrown outward from the edge of the component 32 under the action of centrifugal force. The thrown-out condensed water collides with the atomizing shell 31, thereby generating mist. Because the condensed water is rapidly thrown outward using centrifugal force, it can achieve a high speed by relying on the rapid rotation of the centrifugal rotating component 32, thus improving the atomization effect after impact.

[0131] More importantly, the condensate is thrown outward by centrifugal force, so there is no residue left in the centrifugal rotating part 32. This improves the atomization effect of the condensate, so as to fully and effectively atomize and discharge the condensate, and ultimately improve the reliability of the water heater.

[0132] The return water inlet 314 is connected to the water storage container 4, which is located below the return water inlet 314. Unatomized condensate in the atomizing housing 31 can flow back into the water storage container 4 via the return water inlet 314, and then be pumped back into the water supply pipe 312 by the water pump 41.

[0133] In one embodiment, in order to effectively store condensate and ensure that the condensate can rotate with the centrifugal rotating component 32 so as to use centrifugal force to drive the condensate to be thrown out quickly, a recessed structure 321 is formed on the upper surface of the centrifugal rotating component 32. The recessed structure 321 forms the water storage area and is located below the outlet of the water supply pipe 312.

[0134] Specifically, by forming a recessed structure 321 on the upper surface of the centrifugal rotating component 32, the recessed structure 321 forms a water storage area. In this way, the condensate output from the water supply pipe 312 can be collected in the recessed structure 321, thereby prolonging the time that the condensate follows the centrifugal rotating component 32 in rotation. Under the action of centrifugal force for a long time, the condensate can be thrown out from the edge of the centrifugal rotating component 32 more quickly, thereby increasing the linear velocity of the condensate leaving the centrifugal rotating component 32, which is more conducive to improving the atomization effect.

[0135] In one embodiment, the recessed structures 321 are symmetrically distributed around the rotation axis of the centrifugal rotating component 32 as a center line;

[0136] The outlet of the water supply pipe 312 is arranged close to the rotation axis of the centrifugal rotating component 32.

[0137] Specifically, in order to improve the uniformity of the centrifugal force applied to the condensate and thus enhance the atomization effect, the recessed structure 321 can be a centrally symmetrical structure about the rotation axis of the centrifugal rotating component 32.

[0138] Because the recessed structure 321 is centrally symmetrical, the condensate is more evenly distributed when it rotates within the recessed structure 321. This results in a more even distribution of the condensate thrown out from the edge of the centrifugal rotating component 32. Consequently, the mist generated after the condensate impacts is also more uniform, facilitating the timely discharge of the mist from the exhaust port 311 to the outside of the atomizing shell 31.

[0139] In some embodiments, the recessed structure 321 is funnel-shaped.

[0140] Specifically, the water storage area formed by the funnel-shaped concave structure 321 can store a large amount of condensate and allow the condensate to gradually diffuse and flow outward from the bottom.

[0141] In some embodiments, the surface of the recessed structure 321 is provided with a multi-step surface.

[0142] Specifically, the size of the multi-step surface gradually increases along the direction of the outward flow of condensate. During the rotation of the centrifugal rotating component 32, the condensate will impact the side walls of different step surfaces step by step as it flows outward, thereby achieving the effect of pre-atomizing the condensate.

[0143] In some embodiments, the vertical projection of the outlet of the water supply pipe 312 is close to the low water level position of the water storage area.

[0144] Specifically, in order to ensure that the condensate flowing onto the centrifugal rotating component 32 rotates sufficiently to generate a higher ejection speed using centrifugal force, the water output from the outlet of the water supply pipe 312 will fall to the low water level position in the storage area. In this way, the condensate can start rotating with the centrifugal rotating component 32 from a position close to the axis of the centrifugal rotating component 32, so as to make full use of the upper surface area of ​​the centrifugal rotating component 32 to obtain a sufficiently large ejection speed, thereby producing a better atomization effect after impact.

[0145] In one embodiment, the water pipe 312 extends into the groove formed by the recessed structure 321.

[0146] Specifically, to prevent condensate from splashing onto the outside of the centrifugal rotating component 32 due to excessive height difference, the water supply pipe 312 can be made to extend into the groove formed by the recessed structure 321.

[0147] In another embodiment of this application, in order to further improve the atomization effect generated by the impact of condensate water, the atomizing device 3 further includes a collision component 34, which is located in the atomizing housing 31 and distributed on the outside of the centrifugal rotating component 32.

[0148] The collision component 34 is configured to collide with the condensate ejected by the centrifugal rotating component 32 to generate mist.

[0149] Specifically, the collision component 34 is disposed in the atomizing housing 31 and is arranged outside the centrifugal rotating component 32. In this way, after the condensed water is rotated and thrown out from the centrifugal rotating component 32, the condensed water will directly impact the collision component 34. By using the collision component 34, which is closer to the centrifugal rotating component 32, to impact the condensed water, the condensed water can impact the collision component 34 when it has not decelerated or has only decelerated slightly after being thrown out, so as to optimize the atomization effect of the impact.

[0150] In one embodiment, the collision component 34 has a ring-shaped structure and surrounds the periphery of the centrifugal rotating component 32.

[0151] Specifically, the collision component 34 has an overall ring structure and surrounds the centrifugal rotating component 32. The collision component 34 can collide with the condensed water thrown out from the centrifugal rotating component 32 to form mist.

[0152] In order for the condensed water to accurately impact the collision component 34 after being thrown out, the upper part of the collision component 34 needs to be higher than the upper edge of the centrifugal rotating component 32, while the lower part of the collision component 34 needs to be lower than the upper edge of the centrifugal rotating component 32.

[0153] The physical manifestation of the collision component 34 can have various structural forms, for example, the collision component 34 is an annular impact plate.

[0154] Alternatively, the collision component 34 may include an annular frame 341 and a plurality of impact plates 342, wherein the plurality of impact plates 342 are disposed on the annular frame 341 and a gap is formed between adjacent impact plates 342.

[0155] Specifically, the collision component 34 adopts the structure of an annular impact plate 342, which is installed in the atomizing housing 31 through an annular frame 341. At the same time, the impact plate 342 arranged on the annular frame 341 acts as the main component to collide with the condensate.

[0156] After the condensed water is thrown out from the centrifugal rotating component 32, it will collide with the corresponding impact plate 342 to form mist. The mist can be quickly discharged from the gap between the two impact plates 342, thereby ensuring that the mist generated by the collision can be smoothly discharged from the atomizing housing 31 to the outside through the exhaust port 311.

[0157] In one embodiment, in order to improve the ability of condensate to be fully dispersed and form mist during the collision process, the cross-sectional area of ​​the impact plate 342 increases from the center of the annular frame 341 outwards.

[0158] Specifically, as the condensate ejected from the edge of the centrifugal rotating component 32 moves toward the impact plate 342, the cross-sectional width of the impact plate 342 tends to increase outward. This increases the probability of the condensate colliding with the impact plate 342 during its movement, thus making full use of the impact plate 342 to atomize the condensate.

[0159] If some of the condensate does not collide with the impact plate 342, this portion of condensate will eventually collide with the atomizing shell 31 and eventually form mist.

[0160] The cross-section of the impact plate 342 can be triangular or trapezoidal.

[0161] In one embodiment, to prevent unatomized condensate from entering the air inlet 313 at the bottom of the atomizing housing 31, an annular enclosure 315 can be provided inside the atomizing housing 31 around the air inlet 313, and the return water inlet 314 is arranged on the outside of the annular enclosure 315.

[0162] Specifically, if the condensate that is not atomized in the atomizing housing 31 accumulates at the bottom of the atomizing housing 31, it can be blocked by the annular enclosure 315 to prevent the condensate at the bottom of the atomizing housing 31 from flowing into the air inlet 313 and causing equipment failure.

[0163] In some embodiments, the atomizing housing 31 is a split structure, which includes an upper housing 316 and a lower housing 317. The upper housing 316 is provided with an exhaust port 311, and the lower housing 317 is provided with an air inlet 313, a water return port 314 and an annular barrier 315. The water supply pipe 312, the drive motor 33 and the collision component 34 can be arranged on the upper housing 316.

[0164] By incorporating a centrifugal rotating component within the atomizing housing, a water supply pipe on the housing delivers condensate from the condensation assembly to this component. As the drive motor rotates the centrifugal rotating component, the condensate falling onto it rotates along with it. Under centrifugal force, the condensate is thrown out from the edge of the component. This effectively disperses the condensate and atomizes it upon impact with the atomizing housing, achieving atomization. Furthermore, under centrifugal force, all the condensate on the rotating component is centrifugally ejected, resulting in comprehensive atomization. This enhances the atomization effect of the condensate within the gas water heater, effectively treating the condensate and thus improving the reliability of the gas water heater.

[0165] like Figure 12 As shown, another embodiment of this application also provides a gas water heater, including a water heater body 100, on which an inlet pipe 101, an outlet pipe 102 and a flue pipe 103 are provided, and also includes the aforementioned burner 200;

[0166] The water inlet pipe 101 is connected to the inlet of the condenser heat exchange tube of the burner 200, the water outlet pipe 102 is connected to the outlet of the main heat exchange tube of the burner 200, and the flue pipe 103 is connected to the exhaust port of the atomizing device of the burner 200.

[0167] The first mounting portion and the second mounting portion of the burner are disposed on the water heater body 100.

[0168] Another embodiment of this application also provides a gas-fired heating furnace, including a furnace body, wherein the furnace body is provided with a water inlet pipe, a water outlet pipe and a flue pipe, and also includes the aforementioned burner;

[0169] The water inlet pipe is connected to the inlet of the condenser heat exchange tube of the burner, the water outlet pipe is connected to the outlet of the main heat exchange tube of the burner, and the flue pipe is connected to the exhaust port of the atomizing device of the burner.

[0170] The first mounting portion and the second mounting portion of the burner are disposed on the main body of the heating furnace.
