Description

Technical Field

[0001] The utility model relates to the technical field of hot water supply equipment, in particular to a condensed water neutralizer and a condensing gas water heater. Background Art

[0002] Gas water heaters are an indispensable household appliance in today's home life. Among them, with the scarcity of social energy, condensing gas water heaters are widely used due to their advantages of improving energy utilization and increasing thermal efficiency.

[0003] In the prior art, such as Figure 1 and Figure 2 As shown, when the condensate outlet pipe 13' is entangled or blocked, as the condensate continues to flow in, the water level in the chamber 1' rises, which may compress the air in the chamber 1', forming an air blockage, thereby preventing the water in the neutralizer inlet pipe from continuing to flow into the chamber 1', causing the condensate pipeline to be blocked, and the alarm system cannot be triggered. In order to solve this problem, it is currently common to provide an exhaust hole 2' on the end cover 102' of the neutralizer. When the water in the chamber 1' compresses the air, the air can be discharged through the exhaust hole 2'. Once the water level rises to contact with the liquid level sensor 10', a fault alarm can be triggered. However, this structure may cause the condensate in the chamber 1' to overflow from the top exhaust hole 2', which can easily corrode the components inside the water heater if used for a long time. Utility Model Content

[0004] The first technical problem solved by the present invention is to provide a condensate neutralizer, which effectively solves the problem that the condensate in the existing condensate neutralizer overflows from the exhaust hole and causes corrosion to the internal components of the water heater. By arranging a liquid inlet chamber, a first liquid discharge chamber and a second liquid discharge chamber in the sleeve, there is no need to arrange an exhaust hole on the top of the sleeve, thereby avoiding the condensate in the sleeve from overflowing from the exhaust hole to damage the internal components of the water heater, thereby extending the service life of the components inside the water heater.

[0005] The second technical problem solved by the present invention is to provide a condensing gas water heater, which effectively solves the problem that the condensed water in the existing condensed water neutralizer overflows from the exhaust hole and causes corrosion of the internal components of the water heater. By arranging a liquid inlet cavity, a first liquid discharge cavity and a second liquid discharge cavity in the sleeve, there is no need to arrange an exhaust hole at the top of the sleeve, thereby avoiding the condensed water in the sleeve from overflowing from the exhaust hole to damage the internal components of the water heater, thereby extending the service life of the components inside the water heater.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] A condensate neutralizer, comprising:

[0008] a sleeve, with a liquid inlet provided on the top and a liquid outlet provided on the bottom; an inner cavity provided in the sleeve; a first partition and a second partition provided in the inner cavity; the liquid inlet being located above the first partition; the first partition and the second partition dividing the inner cavity into a liquid inlet cavity, a first liquid discharge cavity and a second liquid discharge cavity; the liquid inlet cavity is communicated with the liquid inlet, the second liquid discharge cavity is communicated with the liquid outlet; the first liquid discharge cavity is surrounded by the first partition and the second partition; a first water outlet is provided on the lower side of the first partition; the liquid inlet cavity is communicated with the first liquid discharge cavity through the first water outlet; a second water outlet is provided on the upper side of the second partition, and the second water outlet is located above the first water outlet; the first liquid discharge cavity is communicated with the second liquid discharge cavity through the second water outlet;

[0009] The liquid level sensor is arranged on the top of the sleeve and extends into the liquid inlet cavity.

[0010] Compared to the prior art, the condensate neutralizer described in this utility model has the following advantages: by providing a first partition and a second partition within the sleeve, the interior of the sleeve is divided into a liquid inlet chamber, a first liquid discharge chamber, and a second liquid discharge chamber, wherein the liquid inlet chamber is connected to the liquid inlet, and the liquid discharge chamber is connected to the second liquid discharge chamber. By providing a first water outlet at the bottom of the first partition, the liquid inlet chamber and the first liquid discharge chamber are connected through the first water outlet. By providing a second water outlet at the top of the second partition, the first liquid discharge chamber and the second liquid discharge chamber are connected through the second water outlet.

[0011] When the condensed water in the liquid inlet pipe enters the liquid inlet cavity from the liquid inlet at the top of the sleeve, the condensed water flows into the first liquid discharge cavity through the first water outlet. Since the second water outlet is arranged above the second partition, when the height of the water surface of the condensed water in the first liquid discharge cavity reaches the second water outlet, the condensed water in the first liquid discharge cavity can pass through the second water outlet and enter the second liquid discharge cavity, and then be smoothly discharged from the liquid outlet at the bottom of the second liquid discharge cavity.

[0012] Since the second water outlet is located above the first water outlet, the water seal surface in the sleeve is at the horizontal plane of the second water outlet, so that the water seal surface is located above the first water outlet. If smoke enters the liquid inlet cavity from the liquid inlet, the water seal surface formed by the condensed water will block the first water outlet, so the smoke can only remain in the liquid inlet cavity and cannot enter the first liquid discharge cavity through the first water outlet, thereby preventing the smoke from being discharged from the liquid outlet.

[0013] When the liquid outlet pipe is entangled, even if the second liquid row cavity is blocked by air, since the liquid inlet cavity and the first liquid row cavity are connected through the first water outlet to form a U-shaped pipeline structure, the condensed water in the liquid inlet pipe can continue to flow into the liquid inlet cavity from the liquid inlet, thereby causing the water surface cover in the sleeve to continue to rise until the water surface cover contacts the liquid level sensor to trigger a fault alarm. Therefore, there is no need to set an exhaust hole at the top of the sleeve, which prevents the condensed water in the sleeve from overflowing from the exhaust hole and damaging the internal components of the water heater, thereby extending the service life of the components inside the water heater.

[0014] In one embodiment, the first partition, the second partition and the inner wall of the sleeve are all configured to be arc-shaped.

[0015] In one embodiment, the second liquid discharge cavity is coaxially arranged with the liquid outlet.

[0016] In one embodiment, a liquid outlet pipe joint extending downward is provided at the liquid outlet, and a liquid inlet pipe joint extending upward is provided at the liquid inlet.

[0017] In one embodiment, the area of ​​the first water outlet is 70mm 2 -90mm 2 .

[0018] In one embodiment, the sleeve includes an open cylindrical body and an end cover provided on the open end of the cylindrical body, and the liquid inlet and the liquid level sensor are respectively staggeredly provided on the end cover.

[0019] In one embodiment, the outer wall of the upper end of the cylinder is provided with an external thread, the inner wall of the end cover is provided with an internal thread, and the end cover is threadedly connected to the cylinder;

[0020] Alternatively, the end cover is connected to the cylinder by welding.

[0021] In one embodiment, the end cover is provided with a reinforcing rib protruding toward the liquid inlet cavity, the reinforcing rib is located between the liquid inlet and the liquid level sensor, and the reinforcing rib shields the liquid level sensor.

[0022] In one embodiment, a drain port communicating with the liquid inlet cavity and the first liquid discharge cavity is formed at the bottom of the sleeve, and an antifreeze drainage joint is connected to the drain port.

[0023] The second technical problem mentioned above is solved by the following technical solution:

[0024] A condensing gas water heater, comprising:

[0025] Liquid inlet and outlet pipes;

[0026] Condensate neutralizer, the liquid inlet pipe is connected to the liquid inlet, and the liquid outlet pipe is connected to the liquid outlet.

[0027] Compared with the background technology, the condensing gas water heater described in the present invention has the following beneficial effects: when the liquid outlet pipe is entangled, even if the second liquid row cavity is blocked by air, since the liquid inlet cavity and the first liquid row cavity are connected through the first water outlet to form a U-shaped pipeline structure, the condensed water in the liquid inlet pipe can continue to flow into the liquid inlet cavity from the liquid inlet, thereby causing the water surface cover in the sleeve to continue to rise until the water surface cover contacts the liquid level sensor to trigger a fault alarm. Therefore, there is no need to set an exhaust hole on the top of the sleeve, which prevents the condensed water in the sleeve from overflowing from the exhaust hole and damaging the internal components of the water heater, thereby extending the service life of the internal components of the water heater.

[0042] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0044] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0046] In related technologies, such as Figure 1 and Figure 2 As shown, when the condensate outlet pipe 13' is entangled or blocked, as the condensate continues to flow in, the water level in the chamber 1' rises, which may compress the air in the chamber 1', forming an air blockage, thereby preventing the water in the neutralizer inlet pipe from continuing to flow into the chamber 1', causing the condensate pipeline to be blocked, and the alarm system cannot be triggered. In order to solve this problem, it is currently common to provide an exhaust hole 2' on the end cover 102' of the neutralizer. When the water in the chamber 1' compresses the air, the air can be discharged through the exhaust hole 2'. Once the water level rises to contact with the liquid level sensor 10', a fault alarm can be triggered. However, this structure may cause the condensate in the chamber 1' to overflow from the top exhaust hole 2', which can easily corrode the components inside the water heater if used for a long time.

[0047] In order to solve the above technical problems, the following Figures 3 to 8 , describing the embodiments of the present utility model.

[0048] According to an embodiment of the present invention, on the one hand, Figures 3 to 6 As shown, a condensate neutralizer is provided, including a sleeve 1, a first partition 4, a second partition 8 and a liquid level sensor 10.

[0049] Specifically, if Figures 3 to 5 As shown, a liquid inlet 2 and a liquid outlet 3 are provided on the sleeve 1, wherein the liquid inlet 2 is provided at the top of the sleeve 1, the liquid outlet 3 is provided at the bottom of the sleeve 1, and an inner cavity is provided in the sleeve 1.

[0050] Specifically, if Figure 4 and Figure 5 As shown, the first partition 4 and the second partition 8 are both arranged in the inner cavity of the sleeve 1, wherein the liquid inlet 2 is arranged above the first partition 4, and the first partition 4 and the second partition 8 divide the inner cavity into a liquid inlet cavity 5, a first liquid discharge cavity 7 and a second liquid discharge cavity 9.

[0051] Specifically, if Figure 4 and Figure 5 As shown, the liquid inlet cavity 5 is communicated with the liquid inlet 2 , the second liquid discharge cavity 9 is communicated with the liquid outlet 3 , and the first partition 4 and the second partition 8 form a first liquid discharge cavity 7 .

[0052] Specifically, if Figure 4 and Figure 5 As shown, a first water outlet 401 is provided on the lower side of the first partition 4 , and the liquid inlet cavity 5 is communicated with the first liquid discharge cavity 7 through the first water outlet 401 .

[0053] Specifically, if Figure 4 and Figure 5 As shown, a second water outlet 801 is provided on the upper side of the second partition 8, and the second water outlet 801 is located above the first water outlet 401. The first drainage cavity 7 is connected to the second drainage cavity 9 through the second water outlet 801.

[0054] Specifically, if Figure 5 As shown, the liquid level sensor 10 is arranged on the top of the sleeve 1 and extends into the liquid inlet chamber 5 .

[0055] This condensate neutralizer divides the interior of the sleeve 1 into a liquid inlet chamber 5, a first liquid discharge chamber, and a second liquid discharge chamber by disposing a first partition 4 and a second partition 8 within the sleeve 1. The liquid inlet chamber 5 communicates with the liquid inlet 2, and the liquid outlet 3 communicates with the second liquid discharge chamber. A first water passage 401 is provided at the bottom of the first partition 4, allowing the liquid inlet chamber 5 to communicate with the first liquid discharge chamber 7 via the first water passage 401. A second water passage 801 is provided at the top of the second partition 8, allowing the first liquid discharge chamber 7 to communicate with the second liquid discharge chamber 9 via the second water passage 801.

[0056] When the condensed water in the liquid inlet pipe enters the liquid inlet chamber 5 from the liquid inlet 2 at the top of the sleeve 1, the condensed water flows into the first liquid drainage chamber 7 through the first water outlet 401. Since the second water outlet 801 is arranged above the second partition 8, when the height of the water surface of the condensed water in the first liquid drainage chamber 7 reaches the second water outlet 801, the condensed water in the first liquid drainage chamber 7 can pass through the second water outlet 801 and enter the second liquid drainage chamber 9, and then be smoothly discharged from the liquid outlet 3 at the bottom of the second liquid drainage chamber 9.

[0057] Since the second water outlet 801 is located above the first water outlet 401, the water seal surface in the sleeve 1 is at the horizontal plane of the second water outlet 801, so that the water seal surface is located above the first water outlet 401. If smoke enters the liquid inlet chamber 5 from the liquid inlet 2, the water seal surface formed by the condensed water blocks the first water outlet 401, so the smoke can only remain in the liquid inlet chamber 5 and cannot enter the first liquid discharge chamber 7 through the first water outlet 401, thereby preventing the smoke from being discharged from the liquid outlet 3.

[0058] When the liquid outlet pipe 13 is entangled, even if the second liquid discharge chamber 9 is blocked by air, since the liquid inlet chamber 5 and the first liquid discharge chamber 7 are connected through the first water outlet 401 to form a U-shaped pipeline structure, the condensed water in the liquid inlet pipe can continue to flow from the liquid inlet 2 into the liquid inlet chamber 5, thereby causing the water surface cover in the sleeve 1 to continue to rise until the water surface cover contacts the liquid level sensor 10 to trigger a fault alarm. Therefore, there is no need to set an exhaust hole at the top of the sleeve 1, which prevents the condensed water in the sleeve 1 from overflowing from the exhaust hole and damaging the internal components of the water heater, thereby extending the service life of the components inside the water heater.

[0059] Specifically, the shape and size of the liquid inlet chamber 5, the first liquid discharge chamber 7 and the second liquid discharge chamber 9 can be adaptively set according to the shape and size of the sleeve 1. In the embodiment of the present application, no specific restrictions are imposed on the structure of the liquid inlet chamber 5, the first liquid discharge chamber 7 and the second liquid discharge chamber 9.

[0060] Specifically, the first separator 4 and the second separator 8 can be configured to be in an arc shape, a wave shape, an elliptical arc shape, etc. In the embodiment of the present application, there is no specific limitation on the shapes of the first separator 4 and the second separator 8.

[0061] Specifically, the first water outlet 401 and the second water outlet 801 can be set in any shape such as a square through hole, a circular through hole or a triangular through hole. In the embodiment of the present application, there is no specific limitation on the shapes of the first water outlet 401 and the second water outlet 801.

[0062] Specifically, the liquid level sensor 10 may be a capacitive liquid level sensor, a photoelectric liquid level switch, etc. In the embodiment of the present application, there is no specific limitation on the type of the liquid level sensor 10.

[0063] Specifically, if Figure 4 and Figure 5 As shown, a top plate 6 is provided on the top of the first partition 4 , and the top plate 6 , the first partition 4 and the corresponding inner wall of the sleeve 1 form a first liquid drainage cavity 7 .

[0064] It should be noted that the liquid inlet 2 should be arranged above the second water outlet 801 so that the condensed water in the liquid inlet 2 can flow normally into the liquid inlet cavity 5 when the liquid outlet pipe 13 is entangled.

[0065] In one embodiment, Figure 4 and Figure 5 As shown, the first partition 4, the second partition 8 and the inner wall of the sleeve 1 are all arranged in an arc shape.

[0066] The inner walls of the first partition 4, the second partition 8 and the sleeve 1 are all arranged in an arc shape, which reduces the corners and dead areas in the liquid inlet chamber 5, the first liquid discharge chamber 7 and the second liquid discharge chamber 9, reduces the risk of impurity deposition and scaling in the condensed water, reduces the possibility of blockage, and extends the service life of the equipment.

[0067] Specifically, if Figure 4 As shown, the diameter of the second partition 8 is smaller than the diameter of the first partition 4 .

[0068] The smaller diameter of second partition 8 helps increase the flow rate of condensate from first drain chamber 7 to second drain chamber 9, thereby optimizing the water flow path, reducing condensate retention and eddy currents, and improving drainage efficiency. Because the diameter of second partition 8 is smaller than that of first partition 4, the volume of second drain chamber 9 is relatively small. When the condensate level rises, the liquid level sensor 10 is triggered more quickly, improving the system's response to water level changes and ensuring timely alarms or measures.

[0069] Specifically, the diameters of the second partition 8 and the first partition 4 are different, so that a first drainage cavity 7 is formed between the second partition 8 and the first partition 4. The size of the first drainage cavity 7 can be set by setting the diameters of the first partition 4 and the second partition 8. In the embodiment of the present application, there is no specific restriction on the diameters of the first partition 4 and the second partition 8.

[0070] In one embodiment, Figure 5 As shown, the second liquid discharge cavity 9 and the liquid outlet 3 are arranged on the same axis.

[0071] The coaxial arrangement of the second drainage chamber 9 and the liquid outlet 3 minimizes the flow path of the condensate from the second drainage chamber 9 to the liquid outlet 3, eliminating any additional turns or branches. This reduces hydraulic losses, allowing the condensate to drain more smoothly and quickly, and improving the drainage efficiency of the condensate neutralizer. Furthermore, the linear flow path reduces the retention of condensate within the second drainage chamber 9, reducing the deposition of impurities in the condensate within the chamber, reducing the risk of fouling and clogging, and extending the service life of the equipment.

[0072] In one embodiment, Figure 5 As shown, a liquid outlet pipe joint 14 is provided at the liquid outlet 3, and the liquid outlet pipe joint 14 is extended downward. A liquid inlet pipe joint 15 is provided at the liquid inlet 2, and the liquid inlet pipe joint 15 is extended upward.

[0073] On the one hand, the downwardly extending liquid outlet joint 14 and the upwardly extending liquid inlet joint 15 provide a more stable pipe connection, reducing loosening caused by vibration or thermal expansion and contraction, and ensuring the long-term reliability of the pipe connection. On the other hand, the downwardly extending liquid outlet joint 14 allows condensed water in the second drainage chamber 9 to be directly discharged, preventing condensed water from accumulating in the liquid outlet joint 14. The upwardly extending liquid inlet joint 15 allows condensed water in the liquid inlet pipe to flow directly into the liquid inlet chamber 5, preventing condensed water from accumulating in the liquid inlet joint 15.

[0074] Specifically, the outer surfaces of the liquid outlet pipe joint 14 and the liquid inlet pipe joint 15 may be provided with corrugations to ensure that the liquid outlet pipe joint 14 is firmly connected to the liquid outlet pipe 13 , and the liquid inlet pipe joint 15 is firmly connected to the liquid inlet pipe.

[0075] In one embodiment, Figure 5 As shown, the area of ​​the first water outlet 401 is 70mm 2 -90mm 2 .

[0076] The area of ​​the first water outlet 401 is limited to 70 mm 2 -90mm 2 If the area of ​​the first water outlet 401 is too large, it may be difficult to form a water seal inside the sleeve 1, causing smoke to be discharged from the liquid outlet 3. If the area of ​​the first water outlet 401 is too small, it may cause gas lock inside the sleeve 1.

[0077] Specifically, the area of ​​the first water outlet 401 can be selected to be 80mm 2 , while ensuring that the condensed water in the liquid inlet cavity 5 can smoothly enter the first row of liquid cavities 7, it is ensured that a water surface cover with a suitable water level can be formed in the sleeve 1.

[0078] In one embodiment, Figure 5 As shown, the sleeve 1 comprises an open cylinder 101 and an end cover 102, wherein the end cover 102 is provided on the open portion of the cylinder 101. The liquid inlet 2 and the liquid level sensor 10 are respectively provided on the end cover 102 in a staggered manner.

[0079] The close connection between the end cap 102 and the cylinder 101 enhances the stability of the overall structure of the sleeve 1. The end cap 102 closes the opening of the cylinder 101, which can prevent external substances such as dust, impurities or foreign matter from entering the cylinder 101, protecting the interior of the sleeve 1 from contamination.

[0080] The liquid inlet 2 and the liquid level sensor 10 are staggered on the end cover 102, which can avoid direct alignment between the liquid inlet 2 and the liquid level sensor 10, reduce the possibility of water flow directly impacting the liquid level sensor 10, ensure that the liquid level sensor 10 correctly feedbacks the liquid level height of the condensed water inside the sleeve 1, and avoids liquid level measurement errors caused by water flow impact.

[0081] Specifically, the cylinder 101 and the end cover 102 can be detachably connected by fasteners or snap-fitting, or can be fixedly connected by welding. In the embodiment of the present application, no specific limitation is imposed on the connection method between the end cover 102 and the cylinder 101.

[0082] In one embodiment, Figure 4 and Figure 5As shown, the outer wall of the upper end of the cylinder 101 is provided with an external thread, and the inner wall of the end cover 102 is provided with an internal thread, and the end cover 102 and the cylinder 101 are detachably connected through the thread.

[0083] The threaded connection provides a simple and quick assembly method. No additional tools are required. The end cover 102 can be installed or removed by simply rotating it manually, which simplifies the installation and maintenance process.

[0084] The end cover 102 and the cylinder 101 may also be fixed by welding to ensure that the end cover 102 and the cylinder 101 are firmly connected.

[0085] Specifically, the threaded connection can cooperate with the sealing ring 16 to form an effective seal, prevent condensed water from leaking, ensure the stability of the environment inside the sleeve 1, and improve the overall sealing and reliability of the sleeve 1.

[0086] In one embodiment, Figure 4 and Figure 5 As shown, the end cover 102 is provided with a reinforcing rib 1021, which is protruding toward the liquid inlet cavity 5. The reinforcing rib 1021 is located between the liquid inlet 2 and the liquid level sensor 10, and the reinforcing rib 1021 covers part of the liquid level sensor 10.

[0087] On the one hand, the provision of reinforcing ribs 1021 significantly enhances the structural strength of end cap 102, reduces deformation caused by external pressure or changes in internal fluid pressure, and ensures the stability and sealing of the connection between end cap 102 and barrel 101. On the other hand, reinforcing ribs 1021 partially shield the liquid level sensor 10, preventing condensed water flowing from the liquid inlet 2 from splashing onto the liquid level sensor 10 and causing measurement errors, thereby ensuring that the liquid level sensor 10 can accurately measure the condensed water level within the sleeve 1.

[0088] Specifically, the reinforcing rib 1021 can be set in any shape such as a rectangle, a strip, a triangle, etc. In the embodiment of the present application, there is no specific limitation on the shape of the reinforcing rib 1021.

[0089] In one embodiment, Figure 5 As shown, a drain port 11 is provided at the bottom of the sleeve 1 , the drain port 11 is communicated with the liquid inlet chamber 5 and the first liquid discharge chamber 7 , and an antifreeze drain connector 12 is connected to the drain port 11 .

[0090] In cold environments, residual moisture inside the sleeve 1 may freeze, causing damage to the sleeve 1. A drain port 11 and an antifreeze drain connector 12 are provided at the bottom of the sleeve 1 to easily drain accumulated water from the liquid inlet chamber 5 and the first liquid discharge chamber 7, preventing freezing and protecting the sleeve 1 from damage caused by low temperatures. The drain port 11 also facilitates regular cleaning and maintenance, allowing users to easily drain accumulated scale or impurities from the liquid inlet chamber 5 and the first liquid discharge chamber 7, keeping the interior of the sleeve 1 clean and extending its service life.

[0091] Specifically, a sealing ring 16 may also be provided at the connection between the antifreeze drainage joint 12 and the drain outlet 11 to prevent condensed water from leaking from the drain outlet 11 .

[0092] Specifically, a connecting ear 17 is provided on the outer wall of the sleeve 1 , and a mounting hole 1701 is opened on the connecting ear 17 . The sleeve 1 is fixedly installed inside the water heater by passing a connecting piece through the mounting hole 1701 .

[0093] According to an embodiment of the present invention, on the other hand, Figures 3 to 8 As shown, a condensing gas water heater is also provided, including a liquid inlet pipe (not shown in the figure), a liquid outlet pipe 13 and a condensed water neutralizer.

[0094] Specifically, the liquid inlet pipe is connected to the liquid inlet 2 , and the liquid outlet pipe 13 is connected to the liquid outlet 3 .

[0095] In this condensing gas water heater, when the liquid outlet pipe 13 is entangled, even if the second liquid discharge chamber 9 is blocked by air, since the liquid inlet chamber 5 and the first liquid discharge chamber 7 are connected through the first water outlet 401 to form a U-shaped pipeline structure, the condensed water in the liquid inlet pipe can continue to flow from the liquid inlet 2 into the liquid inlet chamber 5, thereby causing the water surface cover in the sleeve 1 to continue to rise until the water surface cover contacts the liquid level sensor 10 to trigger a fault alarm. Therefore, there is no need to set an exhaust hole at the top of the sleeve 1 to avoid the condensed water in the sleeve 1 from overflowing from the exhaust hole to damage the internal components of the water heater, thereby extending the service life of the internal components of the water heater.

[0096] The working principle of the condensing gas water heater in this embodiment is described as follows:

[0097] The condensed water is discharged through the condensed water neutralizer: the condensed water generated when the condensing gas water heater is working enters the liquid inlet cavity 5 from the liquid inlet 2 through the liquid inlet pipe, and then the condensed water flows into the first liquid discharge cavity 7 through the first water outlet 401. When the height of the water cover of the condensed water in the first liquid discharge cavity 7 and the liquid inlet cavity 5 (such as Figure 7 When the condensed water reaches the second water outlet 801, the condensed water in the first drainage chamber 7 can pass through the second water outlet 801 and flow into the second drainage chamber 9, and then flow into the liquid outlet 13 from the liquid outlet 3 at the bottom of the second drainage chamber 9, so that the condensed water is discharged smoothly.

[0098] When the liquid outlet pipe 13 is entangled, how to normally trigger the fault alarm of the liquid level sensor 10: When the liquid outlet pipe 13 is entangled, even if the second liquid discharge chamber 9 is blocked by air, since the liquid inlet chamber 5 and the first liquid discharge chamber 7 are connected through the first water outlet 401 to form a U-shaped pipeline structure, the condensed water in the liquid inlet pipe can continue to flow from the liquid inlet 2 into the liquid inlet chamber 5, thereby making the water surface in the sleeve 1 (such as Figure 8 As shown in the figure, the surface of the water layer continues to rise until the water surface contacts the liquid level sensor 10, triggering a fault alarm.

[0099] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
