Description

Technical Field

[0001] This invention relates to the field of water heater technology, and more particularly to a condensate draining mechanism, system, and water heater including the same. Background Technology

[0002] Gas water heaters are common household heating appliances, and their energy efficiency ratings are mainly divided into three levels. Currently, the competition among mainstream manufacturers is focused on level 2 energy efficiency products, while level 1 energy efficiency products have a relatively limited market share due to higher technical barriers and costs. One of the key technologies for achieving level 1 energy efficiency is condensation technology. This technology preheats cold water by recovering waste heat from high-temperature flue gas. During this process, the flue gas temperature drops below the dew point, resulting in weakly acidic condensate. Currently, there are two main discharge paths for condensate treatment in the industry: one is to collect the condensate, neutralize it, and then vaporize it through an atomization module and discharge it with the flue gas; the other is to neutralize it first, and then guide the neutralized condensate through an external pipeline to the sewer for internal discharge.

[0003] The two mainstream condensate drainage methods mentioned above each have their advantages and disadvantages. The advantage of neutralized atomized external discharge is that it eliminates the need for an external drain pipe, greatly improving installation flexibility and convenience. However, its system structure is relatively complex and may generate additional energy consumption and noise. The neutralized internal discharge method is technically mature and reliable, but it must be installed close to a floor drain, imposing specific requirements on installation conditions. Furthermore, it requires users to regularly replace the neutralizing agent, resulting in continuous maintenance costs and consumable dependence. Both methods aim to address the problem of direct discharge of acidic condensate potentially corroding pipes and polluting the environment.

[0004] However, existing gas water heaters typically employ only one type of condensate drainage solution. This limitation restricts their applicability: water heaters supporting only internal drainage cannot be installed in environments without floor drains; products supporting only atomization mode always consume additional electricity and cannot handle situations such as atomization module malfunctions. More importantly, users' actual installation conditions and regional climates vary, and a single mode cannot dynamically adapt to these changes, nor can it achieve an optimal balance between energy consumption, reliability, and convenience based on actual operating conditions. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the limitations of existing water heaters with a single discharge method in terms of applicable conditions, and to provide a condensate discharge mechanism, system and water heater including the same.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] This invention provides a condensate drainage mechanism, comprising a control unit, an atomizing module, a water distribution module, an internal discharge mixing module, and an external discharge module. The water distribution module includes a condensate inlet and three condensate outlets. One of the condensate outlets is connected to the atomizing module, which atomizes the condensate into water vapor for discharge. One of the condensate outlets is connected to the internal discharge mixing module, which is connected to the water inlet pipe of a water heater. One of the condensate outlets is connected to the external discharge module, which discharges the condensate to the outside. The control unit is electrically connected to the water distribution module and is used to switch between the three condensate outlets.

[0008] In this solution, the organization provides users with a comprehensive solution for all scenarios, enabling them to flexibly choose the most suitable discharge mode based on the actual installation environment and operating costs. This greatly expands the universality of product installation; regardless of whether the user's installation environment meets the requirements for internal drainage mixing water discharge such as floor drains, the system can complete condensate drainage. Secondly, the system achieves dynamic optimization of energy efficiency and reduction of energy consumption. Users can choose the discharge mode with the lowest cost according to different operating conditions. For example, under normal conditions, the internal drainage mixing water mode, which does not require additional power, is preferred to avoid the continuous standby and operating power consumption of the atomization mode; in seasons or regions where there is no concern about drain pipe freezing, this mode can also be selected to save overall energy consumption. When installation conditions are limited or to prevent drain pipe freezing in winter, the atomization mode can be activated. Although it generates a small amount of additional power consumption, it avoids frequent system start-ups and shutdowns or efficiency reductions caused by pipe blockage failures, ensuring energy efficiency from the perspective of overall operational stability. This dynamic adjustment method helps to minimize overall energy consumption. In addition, multiple modes serve as backups for each other. When one mode temporarily fails, users can switch to other available modes to ensure that the water heater continues to run without interrupting service, thus improving the fault tolerance of the equipment and the user experience.

[0009] Preferably, the water distribution module includes a three-way solenoid valve, which includes a motor and three water-blocking components respectively covering the three condensate outlets. The motor is electrically connected to the control unit and is used to receive instructions from the control unit and move the water-blocking components to open the desired condensate outlet.

[0010] In this design, the opening and closing control of the three water outlets is integrated into a single solenoid valve, driven by a single motor, achieving a highly compact structure and coordinated operation. This not only saves space occupied by the condensate discharge mechanism but also reduces the additional driving force and power consumption required to perform the operation.

[0011] Preferably, the condensate discharge mechanism further includes a neutralization module, which has openings at both ends. One end is open for condensate to enter, and the other end is open to connect to the condensate inlet of the water distribution module. A neutralizing substance for neutralizing acidity and alkalinity is disposed between the two openings of the neutralization module.

[0012] In this solution, since condensate is generally acidic, it can cause slight corrosion as it flows through various components, leading to damage over time. Neutralizing the acidic condensate with a neutralizing agent reduces the damage to the components and also minimizes environmental pollution after discharge.

[0013] Preferably, the neutralizing agent is calcium carbonate; and / or, the neutralizing agent has a porous and loose structure.

[0014] In this solution, calcium carbonate is a low-cost neutralizing agent. Furthermore, the porous structure provides a large internal contact area and a tortuous flow path for the acidic condensate. As the condensate flows slowly through this structure, its contact time with the neutralizing agent is prolonged, resulting in more thorough and uniform contact. This ensures that the neutralization reaction proceeds efficiently even with minor fluctuations in water flow rate or acid concentration, thus stably producing neutral water with the required pH level.

[0015] Preferably, the condensate discharge mechanism further includes a detection module, which is disposed between the neutralization module and the water separation module for detecting the pH of the neutralized condensate.

[0016] In this solution, regardless of whether the user selects atomization, mixing, or external discharge mode, the acidic condensate is pre-neutralized to near neutral by the neutralization module, eliminating the potential corrosion risk of the acidic liquid to any subsequent path. For atomization mode, the atomization module and internal flow channels are protected; for internal discharge mode, the user's drainage pipes are protected; and even in the rarely used emergency external discharge mode, the instantaneous environmental impact is significantly reduced.

[0017] Preferably, the detection module includes a pH meter, the pH meter includes a detection head disposed at the end, the pH meter is disposed at the condensate inlet, and the tap water in the water inlet pipe of the whole machine in the detection module is used to flush the detection head to calibrate the pH standard.

[0018] In this solution, by using tap water as a calibration reference source, the system can automatically flush and calibrate the sensor head with tap water each time it receives water or during periodic self-tests. This process requires no additional chemical calibration solution and no sensor disassembly, achieving simple and efficient calibration. This effectively eliminates signal drift problems caused by prolonged contact with acidic condensate or environmental changes in the pH meter, ensuring consistently accurate pH measurement results.

[0019] The present invention also provides a water heater, which includes a condensate discharge mechanism as described in any of the above technical solutions.

[0020] Preferably, the water heater further includes a water tank for storing the condensate discharged by the drain module.

[0021] In this solution, the water tank can temporarily store and collect condensate that will be discharged externally, and then discharge it in a unified manner.

[0022] This invention also provides a condensate drainage system, which is applied to the condensate drainage mechanism described in any of the above technical solutions. The condensate drainage system provides users with three drainage modes, which can be switched according to user selection: atomization mode, in which the water distribution module discharges condensate from the condensate outlet connected to the atomization module to the atomization module, and the condensate is discharged through atomization; internal drainage mixing mode, in which the water distribution module discharges condensate from the condensate outlet connected to the internal drainage mixing module to the internal drainage mixing module, and the condensate is discharged through a pipe to the water inlet pipe of the whole machine; external drainage mode, in which the water distribution module discharges condensate from the condensate outlet connected to the external drainage module to the external drainage module, and the condensate is discharged through a pipe to the outside of the whole machine.

[0023] Preferably, the detection module detects the pH of the condensate after neutralization by the neutralization module. The detection module sets a pH standard. If the result of the detection of the neutralized condensate meets the standard, the user can choose the atomization mode or the internal discharge mixing mode for discharge. If the result of the detection of the neutralized condensate does not meet the standard, it is forced to be discharged through the external discharge mode.

[0024] In this solution, a detection module monitors the pH of the neutralized condensate in real time, enabling the system to determine whether the neutralization module is functioning effectively. If the pH level meets the standard, it indicates that the condensate is neutral, and the user can choose between two conventional and environmentally friendly discharge modes: atomization or internal discharge. This ensures that subsequent discharge processes will not corrode the internal atomization element or the user's drain pipes. If the pH level does not meet the standard, the system automatically switches to external discharge mode, effectively preventing substandard acidic condensate from entering the conventional discharge path and causing damage, thus achieving fault-tolerant protection.

[0025] The positive and progressive effects of this invention are as follows:

[0026] This invention provides a condensate drainage mechanism, system, and water heater including the same. The system offers users a comprehensive solution, allowing them to flexibly choose the most suitable drainage mode based on the actual installation environment and operating costs. This greatly expands the product's installation versatility; regardless of whether the user's installation environment meets the requirements for internal drainage (such as floor drains), the system can complete condensate drainage. Secondly, the system achieves dynamic optimization of energy efficiency and reduction of energy consumption. Users can choose the lowest-cost drainage mode according to different operating conditions. For example, under normal conditions, the internal drainage mixed-flow mode, which requires no additional power, is preferred, avoiding the continuous standby and operating power consumption of the atomization mode. In seasons or regions where there is no concern about drain pipe freezing, this mode can also be selected to save overall energy consumption. When installation conditions are limited or to prevent drain pipe freezing in winter, the atomization mode can be activated. Although this generates a small amount of additional power consumption, it avoids frequent system start-ups and shutdowns or efficiency reductions caused by pipe blockage, ensuring energy efficiency from the perspective of overall operational stability. This dynamic adjustment method helps to minimize overall energy consumption. In addition, multiple modes serve as backups for each other. When one mode temporarily fails, users can switch to other available modes to ensure that the water heater continues to run without interrupting service, thus improving the fault tolerance of the equipment and the user experience.

[0055] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0056] like Figures 1 to 6 As shown, this embodiment provides a condensate drainage system that offers three drainage modes for the user, which can be switched according to the user's selection: Atomization mode, where condensate is discharged via atomization; the condensate is atomized using the existing atomization module 701. Internal discharge mixing mode, where condensate is discharged through a pipe to the unit's inlet water pipe; and external discharge mode, where condensate is discharged through a pipe to the outside of the unit, i.e., discharged as wastewater.

[0057] Thus, this system provides users with a comprehensive solution, enabling them to flexibly choose the most suitable discharge mode based on the actual installation environment and operating costs. This greatly expands the universality of product installation; regardless of whether the user's installation environment meets the requirements for internal drainage and mixing water discharge such as floor drains, the system can complete condensate drainage. Secondly, the system achieves dynamic optimization of energy efficiency and reduction of energy consumption. Users can choose the discharge mode with the lowest cost according to different operating conditions. For example, under normal conditions, the internal drainage and mixing water mode, which does not require additional power, can be used first to avoid the continuous standby and operating power consumption of the atomization mode; in seasons or regions where there is no concern about drain pipe freezing, this mode can also be selected to save overall energy consumption. When installation conditions are limited or to prevent drain pipe freezing in winter, the atomization mode can be activated. Although it generates a small amount of additional power consumption, it avoids frequent system start-ups and shutdowns or efficiency reductions caused by pipe blockage, ensuring energy efficiency from the perspective of overall operational stability. This dynamic adjustment method helps to minimize overall energy consumption. In addition, multiple modes serve as backups for each other. When one mode temporarily fails, the user can switch to another available mode to ensure that the water heater 1000 continues to run without interrupting service, thus improving the fault tolerance of the device and the user experience.

[0058] Specifically, such as Figure 2 As shown, the condensate drainage system also includes a neutralization module 705, which neutralizes the acidity / alkalinity of the condensate before it is discharged. Thus, regardless of whether the user selects atomization, mixing, or external discharge mode, the acidic condensate is pre-neutralized to near neutral by the neutralization module 705, eliminating the potential corrosion risk of acidic liquids to any subsequent path. For atomization mode, this protects the atomization module 701 and its internal flow channels; for internal discharge mode, it protects the user's drainage pipes; and even in the rarely used emergency external discharge mode, it significantly reduces the instantaneous environmental impact.

[0059] Furthermore, such as Figure 4 As shown, the condensate drainage system also includes a detection module. This module detects the pH of the condensate after neutralization by the neutralization module 705. The detection module sets a pH standard. If the pH of the neutralized condensate meets the standard, the user can choose either atomization mode or internal discharge mixed water mode for drainage. If the pH of the neutralized condensate does not meet the standard, it is forced to be discharged through external discharge mode. In this way, by monitoring the pH of the neutralized condensate in real time, the system can determine whether the neutralization module 705 is working effectively. If the pH meets the standard, it indicates that the condensate is neutral, and the user can choose between either atomization or internal discharge, both conventional and environmentally friendly discharge modes, ensuring that the subsequent discharge process will not corrode the internal atomization element or the user's drain pipes. If the pH does not meet the standard, the system automatically switches to external discharge mode, which effectively prevents substandard acidic condensate from entering the conventional discharge path and causing damage, achieving the purpose of fault safety protection.

[0060] Furthermore, tap water is circulated through the inlet pipe of the entire unit within the detection module to calibrate the pH standard. Thus, the measurement accuracy of the detection module will drift over time or due to environmental changes. Regular calibration ensures the long-term accuracy of pH measurement data, avoiding misjudgments caused by sensor errors. This prevents the system from misjudging actually neutral water as acidic and forcing the activation of an environmentally unfriendly external discharge mode, and also prevents the system from misjudging actually substandard acidic water as safe and incorrectly activating atomization or internal discharge modes, ensuring that the system always executes safe discharge logic based on accurate data. In addition, the pH standard for tap water is 6.5 to 8.5, a range that is safe and meets national drinking water standards. Using tap water to flush the detection module for pH calibration offers the advantages of simplicity and efficiency.

[0061] like Figures 1 to 3 As shown, this embodiment also provides a condensate drainage mechanism 7. The condensate drainage mechanism 7 uses the condensate drainage system described above. The condensate drainage mechanism 7 includes a control unit, an atomizing module 701, a water distribution module 702, an internal drainage mixing module 703, and an external drainage module 704. The control unit is electrically connected to the water distribution module 702 and is used to switch the condensate drainage mode. Figure 6 As shown, the water distribution box body 7021 includes a condensate water inlet (indicated by the arrow in the figure) and three condensate water outlets (indicated by the arrow in the figure). One of the condensate water outlets is connected to the atomizing module 701, which is used to atomize the condensate water into water vapor for discharge. Another condensate water outlet is connected to the internal drain mixing module 703, which is connected to the water inlet pipe of the water heater 1000. Finally, one of the condensate water outlets is connected to the external drain module 704, which is used to discharge the condensate water to the outside.

[0062] Specifically, such as Figures 4 to 6 As shown, the water distribution module 702 includes a water distribution box body 7021, a water distribution box rear cover 7022 covering the water distribution box body 7021, and a three-way solenoid valve 7023 disposed within the water distribution box body 7021. The three-way solenoid valve 7023 includes a motor and three water-blocking components respectively covering the three condensate outlets. The motor is electrically connected to the control unit and is used to receive commands from the control unit and move the water-blocking components to open the desired condensate outlet. Thus, the opening and closing control of the three outlets is integrated into a single solenoid valve, driven collaboratively by a single motor, achieving a highly compact structure and coordinated operation. This not only saves space occupied by the condensate discharge mechanism but also reduces the additional driving force and power consumption required to perform the operation.

[0063] Specifically, the neutralization module 705 includes a porous, loose structure containing neutralizing substances. This porous structure provides a large internal contact area and a tortuous flow path for the acidic condensate. As the condensate flows slowly through this structure, its contact time with the neutralizing substances is prolonged, and the contact is more thorough and uniform. This ensures that the neutralization reaction proceeds efficiently even with minor fluctuations in water flow rate or acid concentration, thereby stably outputting neutral water with the required pH level.

[0064] In this embodiment, the neutralizing agent is calcium carbonate.

[0065] Furthermore, the detection module includes a pH meter 706, which includes a detection head located at its end. The pH meter 706 is positioned at the condensate water inlet. Tap water flowing through the water inlet pipe of the entire unit is used to flush the detection head to calibrate the pH standard. Thus, by using tap water as a calibration reference source, the system can automatically flush and calibrate the detection head with tap water each time water is added or during periodic self-checks. This process requires no additional chemical calibration solution and no sensor disassembly, achieving simple and efficient calibration. This effectively eliminates signal drift problems caused by prolonged contact with acidic condensate water or environmental changes in the pH meter 706, ensuring consistently accurate pH detection results. Specifically, there are two calibration methods: one is to flush the pH meter 706 after a set working time via a program. This set working time can be freely set by the user; generally, a self-check calibration every 8-10 hours is preferred. The second method involves rinsing the pH meter 706 after each 1000-hour combustion cycle of the water heater, i.e., after the flame goes out and heat exchange stops. Regardless of the calibration method, the device is in a non-operating state during calibration. Tap water needs to be introduced through the condensate outlet connected to the internal drain mixing module 703 for calibration. After calibration, the tap water can be discharged through atomization or external drainage.

[0066] This embodiment also provides a water heater 1000, which includes a shell 1, an inner cavity inside the shell 1, and a condensate drain mechanism 7, a combustion chamber device 2, a fan device 3, a primary heat exchanger 4, a secondary heat exchanger 5, and a flue pipe 6, as described above. The shell 1 is provided with a tap water inlet 101 and a hot water outlet 102, and the tap water inlet 101 flows through the secondary heat exchanger 5 via a pipe. When the water heater 1000 is started, the fan device 3 blows air to supply air, and gas is supplied to the combustion chamber device 2. Figure 2The middle arrow indicates the direction of water flow. The cold water in the pipe first exchanges heat with the high-temperature flue gas generated by the combustion chamber device 2 for preheating, releasing the waste heat of the flue gas. The pipe then flows through the primary heat exchanger 4, where the water undergoes another heat exchange to reach the predetermined temperature before being discharged through the hot water outlet 102. The high-temperature flue gas is discharged through the exhaust pipe 6. A significant amount of condensate is generated at the secondary heat exchanger 5. A collection device is installed at the secondary heat exchanger 5 to collect the condensate. The collected condensate is then piped to the neutralization module 705 for neutralization, and then flows through the pH meter 706 for testing. If the pH meets the standard, the condensate is either atomized or internally discharged for mixing, depending on the user's choice. If atomization is performed, the water distribution module 702 discharges the condensate to the atomization module 701, and the atomized steam is discharged through the existing exhaust pipe 6. If internal discharge for mixing is performed, the condensate is discharged to the pipe at the water inlet 101 for reuse. The outer casing 1 is also provided with a sewage drain outlet 103, which discharges wastewater if it does not meet the standards.

[0067] Furthermore, the water heater 1000 also includes a water tank 8, which is used to store substandard condensate. The water tank 8 is connected to a sewage drain outlet 103. The sewage drain outlet 103 is equipped with a knob-operated cover, which can be manually opened to release the substandard condensate. Alternatively, a pipe can be installed to directly connect the water tank 8 to the household sewer system. In this embodiment, the method of using a cover and manually opening it to release the substandard condensate is adopted.

[0068] The water heater 1000 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the water heater 1000 to perform corresponding operations, thereby improving the user experience.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
