Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a gas water heater. Background Art

[0002] Gas water heaters, such as condensing gas water heaters, have a condensing heat exchanger added to the smoke pipe compared to ordinary gas water heaters. They preheat cold water by absorbing high-temperature flue gas, thereby improving heat conversion efficiency. However, the water contained in the flue gas forms condensed water after being cooled by the condensing heat exchanger, and the condensed water is usually discharged into the sewer through the condensing water drain pipe. Existing condensing gas water heaters generally have an external condensing water drain pipe at the bottom of the condensing heat exchange device. This condensing water treatment method requires pre-buried pipes or reserved installation holes in the installation environment, making the gas water heater more affected by installation environment factors; and the drain pipe is usually exposed to the external environment, which is easily damaged and affects the user's visual quality. Therefore, a condensing gas water heater has emerged. An atomizing device is installed at the bottom of the condensing heat exchange device. When the flue gas is working, it is condensed and heat exchanged in the condensing heat exchanger in the condensing heat exchange device, and then liquefied into water droplets and drip to the bottom of the condensing heat exchange device. The atomizing device atomizes the condensed water to form water mist and discharges it out of the smoke pipe along with the flue gas. There is no need to pre-bury the condensed water discharge pipe or reserve installation pipe holes in the installation environment. However, acidic gases such as CO2 and NOX in the flue gas will dissolve in the condensed water, making it corrosive, thereby shortening the service life of the atomizing device.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] As shown in Fig. 1, Fig. 2 and Fig. 3, in one embodiment, a gas water heater 10 is provided, comprising a condensing heat exchange component 100, an atomizing component 200 and a condensed water treatment component 300. The condensing heat exchange component 100 comprises a first shell 110 and a heat exchanger 120, the first shell 110 is provided with a heat exchange cavity 111, and a smoke inlet 112, a smoke outlet channel 113 and a water outlet 114 respectively connected to the heat exchange cavity 111, and the heat exchanger 120 is arranged in the heat exchange cavity 111. The atomizing assembly 200 includes an atomizing housing 210 and an atomizing device 220 for atomizing condensed water to form water mist. The atomizing housing 210 is provided with an atomizing chamber 211, and the atomizing device 220 is installed at the bottom of the atomizing chamber 211; the atomizing housing 210 is also provided with a water inlet 212 and a mist outlet 213 connected to the atomizing chamber 211, and one end of the atomizing housing 210 provided with the mist outlet 213 extends into the bottom of the heat exchange chamber 111 to form a water retaining portion 214. The condensed water treatment assembly 300 is connected between the water outlet 114 and the water inlet 212, and is used to neutralize the condensed water with acid and then output it to the atomizing chamber 211 through the water inlet 212.

[0032] When the gas water heater 10 in the above embodiment is used, the flue gas exchanges heat with the heat exchanger 120 to generate condensed water, which drips to the bottom of the heat exchange chamber 111 and gathers. Due to the presence of the water retaining portion 214, the condensed water flows through the water outlet 114, the condensed water treatment component 300, the water inlet 212, and finally flows into the atomizing chamber 211. The atomizing device 220 can atomize the condensed water to form water mist that flows out of the smoke outlet channel 113 along with the flue gas, thereby realizing the atomization discharge of the condensed water, without the need for an external condensed water drainage pipe, and improving the applicability and reliability of the gas water heater 10. By providing the water retaining portion 214 and the condensed water treatment component 300, the condensed water needs to be firstly subjected to acid neutralization treatment by the condensed water component and then atomized by the atomizing device 220, thereby preventing the atomizing device 220 from being immersed in an acidic environment for a long time and extending the service life of the atomizing device 220.

[0033] As shown in FIG. 2 and FIG. 3 , further, the condensate treatment component 300 includes a second shell 310 and a condensate treatment component 320. The second shell 310 is provided with a neutralization filter chamber 311. The water outlet 114 is connected to the neutralization filter chamber 311. The top of the neutralization filter chamber 311 is connected to the water inlet 212. The condensate treatment component 320 is installed in the neutralization filter chamber 311 and is used to perform acid neutralization treatment on the condensate. In this way, the condensate will overflow from the top of the neutralization filter chamber 311 to the bottom of the atomization chamber 211 after being filtered in the neutralization filter chamber 311 and the water level is full, ensuring that the condensate treatment component 320 can perform acid neutralization treatment on the condensate, thereby improving the reliability of the gas water heater 10.

[0034] As shown in FIG. 2 and FIG. 3, optionally, there are at least two neutralization filter chambers 311 and condensate treatment components 320, the bottoms of two adjacent neutralization filter chambers 311 are correspondingly connected, and each condensate treatment component 320 is sequentially arranged in each neutralization filter chamber 311 along the flow direction of the condensate. In this way, the bottoms of each neutralization filter chamber 311 are correspondingly connected, so that the water level in each neutralization filter chamber 311 can be kept consistent, so that the condensate can be temporarily accumulated and precipitated in the second housing 310, ensuring that the condensate has sufficient time to penetrate and contact with the condensate treatment component 320 and undergo acid neutralization treatment, thereby achieving a sufficient purification effect.

[0035] Specifically in this embodiment, along the flow direction of the condensed water, the top of the neutralization filter chamber 311 farthest from the atomization shell 210 is connected to the water outlet 114 correspondingly, and the top of the neutralization filter chamber 311 closest to the atomization shell 210 is connected to the water inlet 212 correspondingly.

[0036] Among them, the number of neutralization filter chambers 311 and condensate treatment components 320 can be flexibly adjusted according to the actual needs of use. For example, the number of neutralization filter chambers 311 and condensate treatment components 320 can be two, three or more. The condensate treatment component 320 can be any structure in the prior art that can perform acid neutralization treatment on condensate water. The structures and models of condensate treatment components 320 in different neutralization filter chambers 311 can be the same or different. Specifically in this embodiment, the condensate treatment component 300 can perform acid neutralization, filtration and purification on condensate water.

[0037] As shown in FIG. 1 and FIG. 3, in one embodiment, the gas water heater 10 further includes a neutralizing filter 400 for acid neutralization of condensed water, and the neutralizing filter 400 is arranged at the bottom of the atomizing chamber 211 and around the periphery of the atomizing device 220. In this way, the neutralizing filter 400 can perform real-time acid-base balance on the condensed water in the atomizing chamber 211, avoid the flue gas in the heat exchanger 120 from contacting the condensed water in the atomizing chamber 211, or the influence of the reflux liquid at the smoke outlet channel 113, which causes the condensed water in the atomizing chamber 211 to become weakly acidic again, protect the atomizing device 220 from corrosion by acidic liquid, and improve the reliability and service life of the gas water heater 10. In addition, the neutralizing filter 400 is arranged around the periphery of the atomizing device 220, so that the condensed water formed after the flue gas condenses and flows down along the inner wall of the atomizing chamber 211 is first neutralized by the neutralizing filter 400 and then atomized, thereby extending the service life of the atomizing device 220.

[0038] Optionally, the neutralizing filter element 400 may be configured as a neutralizing filter layer. The neutralizing filter layer is disposed at the drainage side of the bottom of the atomizing chamber 211 and keeps the condensed water in the atomizing chamber 211 neutral.

[0039] As shown in Fig. 1, Fig. 2 and Fig. 3, in one embodiment, the bottom of the first shell 110 is provided with a mounting hole 115 connected to the heat exchange chamber 111, the water retaining portion 214 is set as a cylindrical structure, the top of the water retaining portion 214 passes through the mounting hole 115 and extends into the heat exchange chamber 111, and the outer wall of the water retaining portion 214 is sealed with the inner wall of the mounting hole 115. In this way, the convenience of assembling the gas water heater 10 is improved. In other embodiments, the first shell 110 can also be integrally formed with the atomizing shell 210.

[0040] Specifically in this embodiment, the smoke outlet channel 113 is arranged on the outer side wall of the first shell 110. The water outlet 114 is arranged at the bottom of the first shell 110 and is located outside the water retaining portion 214. The water retaining portion 214 is arranged as a water retaining pipe, and the condensed water treatment component 300 is located below the first shell 110 and outside the water retaining pipe, so that the condensation heat exchange component 100, the atomization component 200 and the condensed water treatment component 300 are integrated. The atomization device 220 can be any structure in the prior art that can atomize the condensed water.

[0041] As shown in Fig. 1, Fig. 2 and Fig. 4, further, the gas water heater 10 also includes a lower water level monitoring device 500, a trigger water level monitoring device 600 and a controller 700. The lower water level monitoring device 500 is installed at the bottom of the water retaining portion 214, and the trigger water level monitoring device 600 is installed on the outer wall of the water retaining portion 214 and is located above the lower water level monitoring device 500. The lower water level monitoring device 500 and the trigger water level monitoring device 600 are both used to monitor the water level of the condensed water in the atomizing chamber 211. The controller 700 is connected to the lower water level monitoring device 500, the trigger water level monitoring device 600 and the atomizing device 220. In this way, when the gas water heater 10 is running, the condensed water in the heat exchange chamber 111 passes through the water outlet 114, the condensed water treatment component 300 and the water inlet 212, and finally flows into the atomizing chamber 211. When the water level of the condensed water in the atomizing chamber 211 reaches the position where the water level monitoring device 600 is triggered, the controller 700 controls the atomizing device 220 to start for atomization processing; when the water level of the condensed water in the atomizing chamber 211 drops to the position where the lower water level monitoring device 500 is located, the controller 700 controls the atomizing device 220 to stop atomization processing to prevent the atomizing device 220 from being damaged due to dry burning, thereby realizing automatic control operation of the water level in the atomizing chamber 211.

[0042] As shown in Figures 2 and 4, the gas water heater 10 may further include an upper water level monitoring device 800 that is communicatively connected to the controller 700. The upper water level monitoring device 800 is installed on the outer wall of the first shell 110 and is located between the smoke outlet channel 113 and the trigger water level monitoring device 600. In this way, when the atomization device 220 fails or the atomization amount is small, causing the atomization speed to fail to keep up with the water level change, the water level in the atomization chamber 211 continues to fluctuate and rise, and condensed water will also accumulate in the heat exchange chamber 111. When the water level of the condensed water in the heat exchange chamber 111 reaches the position of the upper water level monitoring device 800, a drainage warning is triggered. If the water level has not dropped after self-determination and resolution, the fault alarm is promptly issued to prompt the user, thereby improving the reliability of the gas water heater 10.

[0043] Among them, the lower water level monitoring device 500, the trigger water level monitoring device 600 and the upper water level monitoring device 800 can all be any water level monitoring structure in the prior art. The controller 700 can be set as a single chip microcomputer, an editable logic controller 700 or other control structure. The controller 700 can be connected to the lower water level monitoring device 500, the trigger water level monitoring device 600 and the upper water level monitoring device 800 through a data line, a cable, Bluetooth, a wireless communication network technology or other communication methods.

[0044] As shown in FIG. 1 and FIG. 4 , in one embodiment, the gas water heater 10 further includes a sewage discharge assembly 1000, which is connected to the bottom of the condensate treatment assembly 300 and the bottom of the atomization chamber 211. In this way, the sewage discharge assembly 1000 can be used as a reserved emergency treatment device to avoid immediate shutdown affecting the user's use needs at that moment, thereby improving the practicality of the gas water heater 10.

[0045] As shown in FIG. 1 and FIG. 4 , optionally, the sewage discharge assembly 1000 includes a sewage pipe 1010, an electromagnetic sewage valve 1020 and a manual sewage valve 1030. One end of the sewage pipe 1010 is connected to the bottom of the condensate treatment assembly 300 and the bottom of the atomization chamber 211, and the other end is connected to the electromagnetic sewage valve 1020 and the manual sewage valve 1030. The electromagnetic sewage valve 1020 is connected to the controller 700. In this way, when the gas water heater 10 alarms a fault and prompts the user, the controller 700 automatically recognizes and switches to the takeover discharge mode, reminding the user that the emergency treatment mode has been entered, and preferentially opens the electromagnetic sewage valve 1020 and connects the sewage pipe 1010 to discharge condensed water. If the electromagnetic sewage valve 1020 fails and is stuck, the manual sewage valve 1030 can be opened manually from the outside to avoid the immediate shutdown of the gas water heater 10 and affecting the user's use needs at that moment, thereby improving the practicality and experience of the gas water heater 10.

[0046] Optionally, when the emergency treatment mode of the pipe discharge also has a blockage failure and causes poor drainage, it is detected that the sewage pipe 1010 fails to open, and the water level of the condensed water in the heat exchange chamber 111 continues to rise instead of falling, and the gas water heater 10 reports a fault and stops working, preventing the water level from continuing to rise and entering other components through the smoke outlet channel 113, thereby avoiding damage to the gas water heater 10. When the atomization function of the atomization device 220 or the emergency treatment drain pipe returns to normal, the water level of the condensed water in the atomization chamber 211 returns to normal, and the gas water heater 10 re-enters the normal operating state. When the gas water heater 10 is finished using, it will enter the post-cleaning atomization mode, and the condensed water that has not been treated during use will be promptly processed through the post-cleaning atomization mode to complete the closed loop.

[0047] Specifically in this embodiment, a first sewage outlet connected to the neutralization filter chamber 311 is provided at the bottom of the second shell 310, a second sewage outlet connected to the atomization chamber 211 is provided at the bottom end of the atomization shell 210, and one end of the sewage pipe 1010 is connected to both the first sewage outlet and the second sewage outlet.

[0048] As shown in FIG. 2 and FIG. 3 , in one embodiment, the top of the water retaining portion 214 is set as a mist outlet 213, and the smoke outlet channel 113 extends into the heat exchange chamber 111 and extends to the outside of the mist outlet 213. The outer wall of the mist outlet 213 and the inner wall of the smoke outlet channel 113 are separated to form a smoke channel. In this way, the water mist in the atomizing chamber 211 can be directly discharged into the smoke outlet channel 113 through the mist outlet 213, ensuring that the water mist can be discharged in time, thereby improving the reliability of the gas water heater 10.

[0049] As shown in FIG5 , the gas water heater 10 may further include a smoke outlet pipe 900, which is disposed in the smoke outlet channel 113 and is coaxially disposed with the smoke outlet channel 113. In this way, the smoke in the heat exchange chamber 111 can be discharged from the dual channels, and most of the water mist can be discharged from the smoke outlet pipe 900, so that the water mist is separated from the cold wall of the smoke outlet channel 113 as much as possible, reducing the phenomenon of water mist aggregation and liquefaction, enhancing the demisting effect, and improving the reliability of the gas water heater 10.

[0050] As shown in Fig. 1 and Fig. 4, in one embodiment, the gas water heater 10 further includes a water inlet pipe 1100, a water flow sensor 1200, a hot water circulation pump 1300, a fan 1400, a main heat exchanger 1500, a burner 1600, a gas proportional valve 1700, a temperature sensor 1800, a water flow proportional valve 1900, a water outlet pipe 2000 and a smoke exhaust pipe 2100. The water outlet pipe 2000 is connected to the water inlet end of the heat exchanger 120, and the water flow sensor 1200 and the hot water circulation pump 1300 are installed on the water outlet pipe 2000. The fan 1400, the main heat exchanger 1500 and the burner 1600 are correspondingly installed in the combustion chamber, and the fan 1400 is connected to the air inlet. The burner 1600 is connected to the gas proportional valve 1700, the water inlet of the main heat exchanger 1500 is connected to the water outlet of the heat exchanger 120, the water outlet of the main heat exchanger 1500 is connected to the water outlet pipe 2000, and the temperature sensor 1800 and the water flow proportional valve 1900 are installed on the water outlet pipe 2000. The smoke exhaust pipe 2100 is connected to the smoke outlet channel 113.
