Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and in particular to a water heater capable of generating hydrogen-containing and oxygen-containing water and a control method thereof. Background Art

[0002] Existing hot water systems typically use electrolysis to generate hydrogenated and oxygenated water. This electrolysis splits water into hydrogen and oxygen, which are then dissolved in water for user consumption. However, a core drawback of these systems is their single output mode: hydrogenated and oxygenated water are always mixed, preventing users from selecting a single function based on their needs.

[0003] From the perspective of user needs, mixed output modes are difficult to meet diverse application scenarios. For example, hydrogen water is often used in the healthcare field due to its antioxidant properties, while oxygenated water may be more suitable for cleaning or disinfection purposes. Existing technologies lack a flexible function switching mechanism, and users cannot choose a single gas to enhance water quality for different scenarios, resulting in limited functionality. In addition, mixed output may also cause potential problems, such as the instability of hydrogen and oxygen mixtures under specific conditions, or the inability to realize the user's preference for a single gas concentration.

[0004] As users' demands for water quality become increasingly refined, the limitations of existing technologies are becoming increasingly apparent. The market urgently needs a hot water system that can separate hydrogen and oxygen water on demand and support flexible function switching to meet diverse needs such as health and cleanliness, while also improving system safety and stability.

Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only some of the embodiments of the present invention, not all of them.

As used in the description of the embodiments of the present invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] See also Figure 1-Figure 2 The embodiment of the present invention provides a water electrolysis device 100 that can independently output hydrogen-containing water, oxygen-containing water, and hydrogen-oxygen mixed water, thereby meeting the user's various water needs. In order to achieve the above technical objectives, the water electrolysis device 100 includes a housing 10, an anode electrode 20, and a cathode electrode 30. The specific structure is described as follows:

[0034] The shell 10 is provided with an inner cavity, which is divided into a first chamber 11 and a second chamber 12. The bottom of the shell 10 is provided with a water inlet 13 connecting the first chamber 11 and the second chamber 12. The top of the shell 10 is provided with an oxygenated water outlet 14 connecting the first chamber 11 and a hydrogenated water outlet 15 connecting the second chamber 12; the anode electrode 20 is provided in the first chamber 11, and the cathode electrode 30 is provided in the second chamber 12.

[0035] In this embodiment of the present invention, the water electrolysis device 100 achieves physical separation and output of hydrogen and oxygen water by dividing the inner cavity of the housing 10 into a first chamber 11 and a second chamber 12, and providing independent oxygenated water outlets 14 and hydrogenated water outlets 15 at the top. The anode electrode 20 and cathode electrode 30 are respectively arranged in the two chambers, allowing the oxygen and hydrogen generated by the electrolysis reaction to enter their respective chambers in a targeted manner.

[0036] The shared water inlet 13 at the bottom ensures that the water flow is evenly distributed to the two chambers, avoiding fluctuations in electrolysis efficiency caused by uneven water flow. The design of the top outlet, combined with the natural upward movement of gas, optimizes the separation process of gas and water, reduces gas residue, and thus improves the purity of hydrogen-containing water and oxygen-containing water. The chamber separation structure lays the foundation for subsequent functional expansion (such as independent exhaust or mixing control), while simplifying the internal flow channel design of the device and reducing manufacturing costs.

[0037] An embodiment of the present invention provides a water electrolysis device 100, comprising a housing 10, an anode electrode 20, and a cathode electrode 30. The housing 10 has an inner cavity, which is divided into a first chamber 11 and a second chamber 12. The bottom of the housing 10 is provided with a water inlet 13 connecting the first chamber 11 and the second chamber 12. The top of the housing 10 is provided with an oxygenated water outlet 14 connecting the first chamber 11 and the hydrogenated water outlet 15 connecting the second chamber 12. The anode electrode 20 is disposed in the first chamber 11, and the cathode electrode 30 is disposed in the second chamber 12. By dividing the inner cavity of the housing 10 into the first chamber 11 and the second chamber 12 and providing independent oxygenated water outlets 14 and hydrogenated water outlets 15 at the top, the water electrolysis device 100 achieves separate output of hydrogenated water and oxygenated water. Furthermore, the hydrogenated water and oxygenated water can be mixed to obtain hydrogen-oxygen mixed water, thereby meeting the various water needs of users.

[0038] In some preferred embodiments, the water electrolysis device 100 further includes an exchange membrane 40, which is disposed between the first chamber 11 and the second chamber 12, the anode electrode 20 is disposed on the side of the exchange membrane 40 facing the first chamber 11, and the cathode electrode 30 is disposed on the side of the exchange membrane 40 facing the second chamber 12.

[0039] In specific implementations, an exchange membrane 40 is added and positioned between the first chamber 11 and the second chamber 12. The anode electrode 20 and cathode electrode 30 are placed in close proximity to either side of the exchange membrane 40, further enhancing the hydrogen-oxygen separation effect. The exchange membrane 40 acts as a selective barrier, allowing protons or ions to pass through to maintain charge balance in the electrolysis reaction while physically preventing the mixing of hydrogen and oxygen to prevent cross-contamination. The close proximity of the electrodes to the exchange membrane 40 shortens the ion migration path, reduces energy loss during the electrolysis process, and improves reaction efficiency.

[0040] In some preferred embodiments, the water electrolysis device 100 further includes a partition 50 , and the first chamber 11 and the second chamber 12 are separated by the partition 50 ; the partition 50 is provided with a mounting hole, and the exchange membrane 40 is mounted on the mounting hole.

[0041] In specific implementation, the chamber is separated by a partition 50 and mounting holes are provided on the partition 50 to fix the exchange membrane 40, thereby achieving modularity and stability of the chamber structure. The partition 50 serves as a rigid support to ensure that the exchange membrane 40 does not shift or deform during long-term operation, thereby maintaining the reliability of hydrogen and oxygen separation. The precise positioning of the mounting holes allows the exchange membrane 40 to fit tightly with the chamber boundary, preventing water or gas from leaking into adjacent chambers, further improving separation accuracy. The modular design simplifies the assembly and maintenance process of the device, reduces production complexity, and provides flexibility for the adaptation of exchange membranes 40 of different specifications. For example, membrane materials with different performance can be replaced according to needs to optimize system functions.

[0042] In some preferred embodiments, an oxygen outlet 16 and a hydrogen outlet 17 are provided at the top of the shell 10; the oxygen outlet 16 is communicated with the first chamber 11, and the position of the oxygen outlet 16 is higher than the oxygen-containing water outlet 14; the hydrogen outlet 17 is communicated with the second chamber 12, and the position of the hydrogen outlet 17 is higher than the hydrogen-containing water outlet 15.

[0043] Specifically, an oxygen outlet 16 and a hydrogen outlet 17 are located at the top of the housing 10, positioned higher than the oxygenated water outlet 14 and hydrogenated water outlet 15. Due to their lower density, oxygen and hydrogen naturally rise to the outlets, while the gas-laden water flows out through the lower outlets. This high-position exhaust design also prevents water from backflowing into the exhaust channel. By physically separating the exhaust and water outlet paths, the system can dynamically adjust gas emissions, for example, prioritizing exhaust when excess gas is present.

[0044] In some preferred embodiments, the water electrolysis device 100 includes a first exhaust valve 60 and a second exhaust valve 70 , wherein the first exhaust valve 60 is connected to the oxygen exhaust port 16 , and the second exhaust valve 70 is connected to the hydrogen exhaust port 17 .

[0045] In specific implementations, the first exhaust valve 60 and the second exhaust valve 70 are connected to the oxygen exhaust port 16 and the hydrogen exhaust port 17, respectively, enabling active control of gas emissions. The exhaust valves (first exhaust valve 60 and second exhaust valve 70) can be dynamically opened and closed based on gas pressure or user instructions. For example, they automatically open when gas (hydrogen and oxygen) accumulation reaches a preset threshold, thus preventing safety hazards caused by excessive pressure in the chamber (such as membrane rupture or seal failure).

[0046] Furthermore, an embodiment of the present invention provides a water heater that can produce hydrogen-containing and oxygen-containing water, the water heater comprising the water electrolysis device 100, a water inlet pipe 200, a water outlet pipe 300, a first controllable valve 400, and a second controllable valve 500 as provided in any of the above embodiments; the water inlet pipe 200 is connected to the water inlet 13 of the water electrolysis device 100, the oxygenated water outlet 14 of the water electrolysis device 100 is connected to the water outlet pipe 300 through the first controllable valve 400, and the hydrogenated water outlet 15 of the water electrolysis device 100 is connected to the water outlet pipe 300 through the second controllable valve 500.

[0047] In a specific implementation, the electrolysis water device 100 is integrated with the water inlet pipe 200, the water outlet pipe 300 and the controllable valve to form a water heater system that can flexibly switch the output mode. By controlling the opening and closing of the first controllable valve 400 (oxygenated water outlet 14) and the second controllable valve 500 (hydrogenated water outlet 15), the user can independently choose to output single hydrogenated water, oxygenated water or hydrogen-oxygen mixed water. The water inlet pipe 200 provides a water source for the electrolysis water device 100, and the water outlet pipe 300 transports the treated water to the user terminal (such as a shower) to form a closed-loop water flow system. The synergistic effect of the valve control logic and the electrolysis water device 100 not only retains the ordinary water function of the traditional water heater, but also expands the application scenarios of functional water quality output to meet diverse needs such as health and cleanliness.

[0048] In some preferred embodiments, the water heater further includes a pure water system 600 and a third controllable valve 700 ; the water inlet pipe 200 is connected to the pure water system 600 through the third controllable valve 700 , and the pure water system 600 is connected to the water inlet 13 of the water electrolysis device 100 .

[0049] In a specific implementation, a pure water system 600 and a third controllable valve 700 are added to ensure that the water source entering the electrolysis device 100 is purified to remove impurities and ion interference. The pure water system 600 (such as a reverse osmosis or filtration module) can improve the efficiency of the electrolysis reaction and avoid performance degradation caused by electrode scaling or membrane contamination. The third controllable valve 700 is used to control the connection between the pure water system 600 and the electrolysis device 100, for example, to shut off the pure water supply when the user uses ordinary water to reduce resource waste. This design extends the life of the core components of the electrolysis device 100 (such as electrodes and exchange membrane 40), while ensuring that the output hydrogen-containing water or oxygen-containing water meets hygiene standards and avoids the risk of secondary pollution.

[0050] Furthermore, the wastewater outlet of the pure water system 600 is connected to the water outlet pipeline 300 , and the wastewater generated by the pure water system 600 can be discharged along the water outlet pipeline 300 .

[0051] In some preferred embodiments, the water heater further comprises a heat exchanger 800, a burner 900, and an air intake valve 910. The heat exchanger 800 is connected to the water inlet pipe 200 and the water outlet pipe 300, respectively. The air intake valve 910 is connected to the burner 900 to control the air intake of the burner 900; the burner 900 is used to heat the heat exchange medium in the heat exchanger 800. The heat exchanger 800 is used to heat the water input from the water inlet pipe 200 to produce hot water, which can be mixed with the hydrogen-containing water and / or oxygen-containing water output from the water electrolysis device 100 in the water outlet pipe 300.

[0052] Further, see Figure 3 An embodiment of the present invention provides a water heater control method, which is applied to the water heater capable of generating hydrogen-containing and oxygen-containing water provided in any of the above embodiments. The method comprises the following steps:

The first controllable valve, the second controllable valve, and the third controllable valve are all connected to the controller and can be controlled by the controller.

[0055] Upon receiving the hydrogen-containing water output command, the third controllable valve is opened, the pure water system operates, and pure water is output to the water electrolysis device. The water electrolysis device operates to generate hydrogen and oxygen. The second controllable valve is opened, and the hydrogen-containing water is output to the water outlet pipeline. Simultaneously, the heat exchanger outputs hot water to the water outlet pipeline. Oxygen can be discharged through the first exhaust valve.

[0056] S2: If an oxygenated water output instruction is received, the third controllable valve and the first controllable valve of the water heater are opened, and the second controllable valve of the water heater is closed.

[0057] In a specific implementation, upon receiving an oxygenated water output command, the third controllable valve is opened, the pure water system operates, and pure water is output to the electrolytic water device. The electrolytic water device then operates to generate hydrogen and oxygen. The first controllable valve is opened, and the oxygenated water is output to the outlet pipe. Simultaneously, the heat exchanger outputs hot water to the outlet pipe. Hydrogen can be discharged through the second exhaust valve.

[0058] S3: If a hydrogen-oxygen mixed water output instruction is received, the first controllable valve, the second controllable valve and the third controllable valve of the water heater are opened.

[0059] In a specific implementation, when the hydrogen-oxygen mixed water output instruction is received, the third controllable valve is opened, the pure water system is operated, and pure water is output to the water electrolysis device; the water electrolysis device operates to produce hydrogen and oxygen; the first controllable valve and the second controllable valve are opened, and oxygen-containing water and hydrogen-containing water are output to the water outlet pipeline at the same time; at the same time, the heat exchanger outputs hot water to the water outlet pipeline.

[0060] Furthermore, in some embodiments, the following steps are also included:

[0061] S4: If the hydrogen-containing water output instruction, the oxygen-containing water output instruction, and the hydrogen-oxygen mixed water output instruction are not received, close the first controllable valve, the second controllable valve, and the third controllable valve of the water heater.

[0062] In a specific implementation, when the hydrogen-containing water output instruction, the oxygen-containing water output instruction and the hydrogen-oxygen mixed water output instruction are not received, the first controllable valve, the second controllable valve and the third controllable valve of the water heater are closed, and the water heater outputs ordinary hot water.
