[0002] Existing condensing gas water heaters produce weakly acidic condensate during operation. This condensate contains components such as carbonic acid, nitrite, and sulfurous acid, which are corrosive.

[0022] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0023] Please refer to Figures 1-11 This utility model provides a condensation atomization device, including a condensation box, a heat exchange tube 3, and an atomizer 4. The condensation box includes a condensation box body and a condensation chamber 100 disposed within the condensation box body. The condensation box body has a flue gas outlet 82, a flue gas inlet 12, and a condensate water outlet 13, all of which are connected to the condensation chamber 100. An atomization structure is disposed within the condensation chamber 100. The atomization structure includes an atomization box 21 and an exhaust structure 22 disposed on the upper side of the atomization box 21. The atomization box 21 includes an atomization box body 211 and an atomization chamber 200 disposed within the atomization box body 211.

The atomization chamber 200 is connected to the exhaust chamber 300, and the upper end of the exhaust chamber 300 is connected to the flue gas outlet 82 and / or the condensation chamber 100. Heat exchange tube 3 is disposed in condensation chamber 100. Atomizer 4 is installed in atomization chamber 200, and atomizer 4 includes atomizer body 41 and atomizing plate 43 disposed on atomizer body 41. Specifically, high-temperature flue gas flows along... Figure 10 and Figure 11 The flue gas enters the condensing chamber 100 through the inlet 12 and flows upward, as indicated by the middle arrow A. The heat exchange tube 3 condenses the high-temperature flue gas entering the condensing chamber 100 through the inlet 12 to form condensate. The condensate enters the atomizing chamber 200 through the condensate outlet 13. The atomizer 4 operates, and the atomizing plate 43 vibrates, atomizing the condensate in the atomizing chamber 200 into water vapor. As the high-temperature flue gas exits through the condensing chamber 100 and exits through the exhaust port 82, a negative pressure is formed at the upper end of the condensing chamber 100, which allows the water vapor to flow upward. Figure 10 and Figure 11 The exhaust gas, as indicated by arrow B, is discharged through exhaust structure 22 to the upper end of condensation chamber 100, and then, along with the flue gas... Figure 10 and Figure 11 The gas water heater discharges water in the direction indicated by arrow C, thus solving the problem in existing technologies where users need to periodically treat condensate or install a dedicated condensate drain to discharge it. Secondly, by setting the atomization structure as a split atomization box 21 and exhaust structure 22, it is convenient to set a shielding part 224 on the exhaust box 221, and at the same time, it is convenient to set the atomizer 4 in the atomization chamber 200, which facilitates the production and manufacturing of the product.

[0024] Optionally, the exhaust structure 22 further includes a shielding portion 224 disposed on the inner wall of the exhaust chamber 300. The atomizer 4 includes an atomizer body 41 and a misting plate 43 disposed on the atomizer body 41. The shielding portion 224 is located above the misting plate 43 and is used to shield the atomized water vapor column generated by the misting plate 43. By providing the shielding portion 224 on the inner wall of the atomizing chamber 200, the water vapor column generated when the misting plate 43 vibrates (the water vapor column passes through...) Figure 10 and Figure 11 The water is shot in the direction indicated by the middle arrow D onto the shielding part 224, causing some of the larger water droplets that cannot be carried away by the smoke to fall back into the atomizing chamber 200 and be re-atomized, so as to reduce the amount of water vapor column formed by the vibration of the atomizing plate 43 and sprayed out of the condensation chamber 100.

[0025] Optionally, the shielding part 224 is provided with a louver structure 2241, which can both block the water vapor column generated when the fog slat vibrates and allow the water vapor to flow out through the louver, thereby improving the smoothness of water vapor flow.

[0026] Optionally, two misting plates 43 and two shielding parts 224 are provided, with each misting plate 43 and shielding part 224 corresponding to the other. One misting plate 43 is provided at the left end and one at the right end of the atomizer body 41, and one shielding part 224 is provided on the left side wall and one on the right side wall of the exhaust chamber 300. The two shielding parts 224 are spaced apart and are both inclined upward toward the center of the exhaust chamber 300 to guide the airflow upward.

[0027] Optionally, the louver structure 2241 is located at a position near the middle of the exhaust chamber 300 in the shielding part 224. This position is not at the center of the water vapor column spray generated when the shielding mist fin vibrates, thereby reducing the water flow splashed out of the condensation chamber 100 through the louver.

[0028] Optionally, the exhaust box 221 is also provided with a mixing hole 222 that connects the condensation chamber 100 and the exhaust chamber 300, so that some of the flue gas in the condensation chamber 100 can enter the exhaust chamber 300 through the mixing hole 222 in the direction shown by arrow E in the figure, take away the water vapor in the exhaust chamber 300, so that the water vapor can flow upward more smoothly and then enter the exhaust port 82.

[0029] Optionally, two mixing holes 222 are provided, with the two mixing holes 222 arranged opposite each other to improve the uniformity of flue gas entering the exhaust chamber 300. Of course, the mixing holes 222 can also be provided in other quantities, such as three or more, with the three or more mixing holes 222 evenly arranged on the exhaust box 221.

[0030] Optionally, the mixing port 222 is located below the shielding part 224 so that the flue gas can carry away a large amount of water vapor located below the shielding part 224.

[0031] Optionally, an overflow port 302 communicating with the condensation chamber 100 is provided at the bottom of the exhaust box 221 or on the atomizing box 211. The atomizing plate 43 is set below the overflow port 302 so that the water in the atomizing chamber 200 can be set above the atomizing plate 43 and will not flow out from the overflow port 302.

[0032] Optionally, the height difference between the atomizing plate 43 and the overflow port 302 is the maximum atomization liquid level H, where 35mm≤H≤45mm.

[0033] Optionally, the mixing hole 222 is positioned higher than the overflow port 302 to prevent condensate in the atomizing chamber 200 from flowing out through the mixing hole 222 and affecting the entry of flue gas into the exhaust chamber 300.

[0034] Optionally, the atomizer 4 also includes a level switch 42 disposed on the atomizer body 41. The level switch 42 is used to detect the level of condensate in the atomizing chamber 200. When the level of condensate in the atomizing chamber 200 is higher than the level switch 42, the atomizer 4 operates, and the atomizing plate 43 vibrates to atomize the condensate in the atomizing chamber 200 into water vapor. When the level of condensate in the atomizing chamber 200 is lower than the level switch 42, the atomizer 4 stops operating.

[0035] Optionally, it also includes a gas guiding structure, which is disposed within the condensing chamber 100 and located above the flue gas inlet 12. The gas guiding structure has multiple groups of gas guiding holes, and the heat exchange tube 3 is disposed above the gas guiding structure and surrounds the outer side of the atomizing structure. By setting up the gas guiding structure, some of the high-temperature flue gas can flow to a position in the condensing chamber 100 away from the flue gas inlet 12, and then be uniformly heated by the heat exchange tube 3, thereby improving the heat exchange efficiency.

[0036] Optionally, the flue gas inlet 12 is located on the periphery of the condenser box, and the air guiding structure includes a first air guiding plate 223 and a second air guiding plate 121. The first air guiding plate 223 is horizontally disposed at the bottom end of the exhaust box 221. The second air guiding plate 121 is vertically disposed at the upper end of the flue gas inlet 12 and is adjacent to the first air guiding plate 223. The air guiding hole group includes a first air guiding hole 2231 disposed on the first air guiding plate 223 and a second air guiding hole 1211 disposed on the second air guiding plate 121. In this way, the high-temperature flue gas entering through the flue gas inlet 12 can be more evenly distributed in the condenser chamber 100, thereby improving the heat exchange uniformity of the heat exchange tube 3.

[0037] Optionally, the device also includes a heater 5 and a temperature detector 6, both of which are located within the atomizing chamber 200. The temperature detector 6 detects the water temperature of the condensate within the atomizing chamber 200, and the heater 5 heats the condensate based on this temperature information. Specifically, when the temperature detector 6 detects that the water temperature of the condensate within the atomizing chamber 200 is too low, the condensate is prone to freezing, making it difficult for the atomizer 4 to generate water vapor. In this case, the heater 5 is needed to heat the condensate within the atomizing chamber 200 to a suitable temperature (generally 20°C) before atomizing the condensate into water vapor.

[0038] Optionally, the outer periphery of the exhaust box 221 is provided with multiple first limiting ribs, and the inner wall of the condenser box is provided with multiple second limiting ribs 17. The heat exchange tube 3 is disposed between the first limiting ribs and the second limiting ribs 17. By setting the first limiting ribs and the second limiting ribs 17, the heat exchange tube 3 is centrally positioned between the exhaust box and the condenser box, which facilitates the uniform flow of flue gas to all positions of the heat exchange tube 3.

[0039] Optionally, both the first limiting rib and the second limiting rib 17 are arranged along the setting direction to facilitate the flow of flue gas and reduce resistance to the flue gas.

[0040] Optionally, the condenser box includes a bottom box 1 and a lid 8. The lid 8 includes a lid body 81, and the bottom box 1 includes a box body 11.

The exhaust port 82 is provided on the lid body 81, and the exhaust port 12 and the condensate water outlet port 13 are both provided on the box body 11. The atomizing box 211 is integrally formed with the bottom box 1. The box body 11 is also provided with a condensate water inlet port 14 that communicates with the atomizing chamber 200. The condensate water outlet port 13 communicates with the condensate water inlet port 14. The structure is simple and easy to produce and assemble.

[0041] Optionally, the exhaust structure 22 also includes multiple support rods 225 disposed on the upper end of the exhaust box 221. A vent hole 301 is formed between two adjacent support rods 225. The vent hole 301 is connected to the smoke outlet 82, the exhaust chamber 300, and the condensation chamber 100. The flue gas in the condensation chamber 100 flows into the smoke outlet 82 through the vent hole 301, carrying the water vapor in the exhaust chamber 300. The upper end of the support rod 225 abuts against the lower side of the cover body 81, thereby providing further support between the cover body 81 and the exhaust box 221 and improving the installation stability of the cover 8 and the exhaust box 221.

[0042] Optionally, it also includes a condensate neutralization component and a water pump 101. The inlet end of the condensate neutralization component is connected to the condensate outlet port 13. The condensate neutralization component is used to neutralize the condensate. The inlet end of the water pump 101 is connected to the outlet end of the condensate neutralization component. The outlet end of the water pump 101 is connected to the atomizing chamber 200. The water pump 101 pumps the water in the condensate neutralization component to the atomizing chamber 200.

[0043] Optionally, the condensate neutralization component includes a water storage box 91 and filter media 92 disposed within the water storage box 91. The upper end of the water storage box 91 is connected to the condensate outlet port 13, and the lower end of the water storage box 91 is connected to the inlet of the water pump 101. The condensate in the condensation chamber 100 flows out through the condensate outlet port 13 into the water storage box 91, is neutralized by the filter media 92 in the water storage box 91, and is then pumped into the atomizing chamber 200 by the water pump 101.

[0044] Optionally, the condensate neutralization component also includes a level detector 93 disposed on the upper end of the water storage box 91. The level detector 93 is used to detect the condensate level in the water storage box 91. When the condensate level in the water storage box 91 is higher than the level detector 93, the water pump 101 runs for a preset time and pumps the condensate in the water storage box 91 to the atomizing chamber 200 for atomization.

[0045] Furthermore, if the condensate level in the water storage box 91 is still higher than the level detector 93 after the water pump 101 is turned off, it indicates that the water pump 101 cannot pump water or the atomizer 4 cannot atomize the condensate. At this time, the gas water heater will shut off and the atomization discharge fault will be alarmed.

[0046] Optionally, the base box 1 also includes an end cap structure 7. The box body 11 also has a mounting channel 16 connecting the atomizing chamber 200 to the outside of the box body 11. The end cap structure 7 is installed in the mounting channel 16 to seal the mounting hole. The end cap structure 7 includes an end cap body 71 and a fixing plate 72.

The wire 44 extends out of the base box 1 through the first mounting hole 711 and connects to the controller 103 of the gas water heater. The temperature detector 6 extends into the atomizing chamber 200 through the second mounting hole 713, and the heater 5 extends into the atomizing chamber 200 through the third mounting hole 712. The fixing plate 72 is connected to the end cap body 71 by screws, so that the temperature detector 6 and the heater 5 can be fixedly mounted on the end cap body 71 by the fixing plate 72.

[0047] Furthermore, the atomizer 4 also includes a sealing ring 45 sleeved on the outside of the wire 44. The sealing ring 45 is disposed between the wire 44 and the hole wall of the first mounting hole 711 to seal the gap between the wire 44 and the first mounting hole 711 and prevent water in the atomizing chamber 200 from flowing out through the gap.

[0048] Optionally, the box body 11 is also provided with a heat exchange inlet 151 and a heat exchange outlet 152. The inlet end of the heat exchange tube 3 extends out of the box body 11 from the heat exchange inlet 151, and the outlet end of the heat exchange tube 3 extends out of the box body 11 from the heat exchange outlet 152.

The flue gas outlet of the gas heat exchanger 102 is connected to the flue gas inlet 12. A fan 106 is disposed between the flue gas outlet and the flue gas inlet 12 so that the high-temperature flue gas in the gas heat exchanger 102 can be drawn by the fan 106 to the condensation chamber 100, and then discharged from the exhaust port 82 carrying the water vapor in the exhaust chamber 300.

One end of the cold water section 104 is connected to the tap water pipe outside the gas water heater, and the other end of the cold water section 104 is connected to the inlet end of the heat exchange pipe 3. The hot water section 105 passes through the gas heat exchanger 102, and one end of the hot water section 105 is connected to the outlet end of the heat exchange pipe 3, while the other end of the hot water section 105 is connected to the hot water pipe outside the gas water heater. The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
