Technical Field

[0001] The present application relates to the technical field of gas water heaters, and in particular to a gas water heater that consumes pure water to produce hydrogen-containing water and a control method thereof. Background Art

[0002] In recent years, with the growing popularity of healthy living concepts, hydrogen-containing water has become a hot topic in the market due to its potential health benefits, such as antioxidants and anti-inflammatory properties. While traditional gas water heaters can provide domestic hot water, their limited functionality makes them unable to meet users' demand for hydrogen-containing water. Existing standalone hydrogen production equipment (such as electrolyzers) often requires additional components such as hydrogen storage tanks and booster pumps, making them bulky and difficult to integrate with water heaters. Users must purchase and install these components separately, making it difficult to achieve instant hydrogenation of hot water. Summary of the Invention

[0025] In a possible implementation, the preset start threshold is 2.5 L / min.

[0026] Compared with the prior art, the beneficial effects of the present application are as follows: the present application provides a gas water heater that consumes pure water to produce hydrogen-containing water and a control method thereof, which realizes the instant preparation of hydrogen-containing water and the simultaneous optimization of hot water supply by integrating the hydrogen generation system with the water heating system: the water electrolysis device is directly connected in series between the booster water pump and the gas dissolving tank, and the hydrogen generated by electrolysis does not need to be temporarily stored in an independent storage tank, but is directed into the gas dissolving tank through the exhaust component; at the same time, the water flow heated by the heat exchanger is synchronously injected into the gas dissolving tank, and is dynamically mixed and dissolved with the hydrogen in the tank.

[0048] In order to solve the technical problems of high installation cost and difficulty in achieving real-time hydrogenation of hot water in the existing technology, the present application provides a gas water heater that consumes pure water to produce hydrogen-containing water and a control method thereof. The hydrogen production module is embedded in the water heater body, and redundant hydrogen storage units and external pipelines are eliminated through pipeline reuse and sharing of the dissolved gas tank 3, which not only compresses the equipment volume but also couples the hydrogen generation with the hot water heating process, thereby achieving instant heating and dissolution of hydrogen-containing hot water in a single device, significantly improving the convenience of healthy hot water supply and system energy efficiency.

[0049] See also Figures 1 to 7, an embodiment of the present application provides a gas water heater that consumes pure water to produce hydrogen-containing water, including: a dissolving tank 3 for dissolving hydrogen in heated water to produce hydrogen-containing water; a hydrogen generation system 1, the hydrogen generation system 1 includes a water electrolysis device 11, a booster water pump 12 and a pure water tank 13, the water outlet 134 of the pure water tank 13 is connected to the water inlet pipeline of the booster water pump 12, the water outlet 134 of the booster water pump 12 is connected to the water inlet pipeline of the electrolysis device 11, and the exhaust port of the electrolysis device 11 is connected to the inlet pipeline of the dissolving tank 3; a water heating system 2, the water heating system 2 includes a burner 21, a heat exchanger 22 and a controller 23, the controller 23 is communicatively connected to the burner 21, the burner 21 is connected to the heat exchanger 22, a water pipe to be heated 24 is arranged around the outer circumference of the heat exchanger 22, and the water outlet 134 of the water pipe to be heated 24 is connected to the inlet pipeline of the dissolving tank 3.

[0050] Specifically, the pure water tank 13 continuously supplies pure water to the booster pump 12, which then feeds the pressurized pure water into the electrolytic water device 11 for electrolysis. The hydrogen generated by electrolysis is transported to the inlet of the gas dissolving tank 3 via the exhaust assembly. In the water heating system 2, the water in the water pipe 24 to be heated passes through the heat exchanger 22 and is heated by the burner 21 before being directly introduced into the gas dissolving tank 3 to mix with the hydrogen. The controller 23 synchronously adjusts the power of the burner 21 and the hydrogen production rate of the electrolytic water device 11 according to the hot water demand. The electrolytic hydrogen production module and the gas heating module are seamlessly connected through the gas dissolving tank 3, achieving simultaneous operation of pure water electrolysis, hydrogen dissolution, and hot water heating, resulting in a compact device structure. The heated high-temperature water flow and the electrolytic hydrogen are dynamically mixed in the gas dissolving tank 3, using the water temperature to increase the solubility of hydrogen, avoiding the risk of secondary contamination caused by the external hydrogen storage tank. The independent circulation of pure water electrolysis and the heating water circulation are separated to prevent residual impurities from electrolysis from interfering with the heating water circuit, ensuring the purity of the hydrogen-containing water and heating efficiency.

[0051] like Figure 2 As shown, the pure water tank 13 and the booster water pump 12 are connected through the water tank connecting pipe 135 and the water pump connecting pipe 121. A first three-way valve 14 is provided between the water tank connecting pipe 135 and the water pump connecting pipe 121. The first three-way valve 14 is provided with two inlets and one outlet. The two inlets are respectively connected to the water tank connecting pipe 135 and the external pure water machine, and the outlet is connected to the water pump connecting pipe 121.

[0052] Specifically, the lower inlet of the first three-way valve 14 is connected to the pure water tank 13 through a water tank connecting pipe 135 and is provided with a second one-way valve 136 to prevent water from flowing back into the pure water tank 13 and causing water overflow. The left inlet is connected to an external pure water machine through an external pipe. When the external pure water machine is not connected, it is sealed by a pure water cover 141 to prevent the pure water in the pure water tank 13 from leaking out of the left inlet. The outlet is connected to the water inlet of the booster water pump 12 through a water pump connecting pipe 121. By switching the valve core position, the pure water tank 13 or the external pure water machine can be selected as the water source for the booster water pump 12. When the water storage capacity of the pure water tank 13 is insufficient, it can be switched to the external pure water machine for direct water supply to avoid interruption of the hydrogen production system due to water shortage. The external pure water machine can be used as a temporary water source without disassembling the water tank, which is convenient for cleaning or maintenance of the pure water tank 13.

[0053] like Figure 2 As shown, the electrolytic water device 11 and the gas dissolving tank 3 are connected through the air inlet connecting pipe 116 and the gas dissolving tank connecting pipe 31. A second three-way valve 15 is provided between the air inlet connecting pipe 116 and the gas dissolving tank connecting pipe 31. The second three-way valve 15 has two inlets and one outlet. The top inlet is connected to the air inlet connecting pipe 116, the right inlet is connected to the water inlet connecting pipe, and the bottom outlet is connected to the gas dissolving tank connecting pipe 31. A third one-way valve 117 is also provided above the top inlet.

[0054] Specifically, the second three-way valve 15 selects hydrogen to be introduced into the dissolved gas tank 3 alone or mixed with the incoming water and then introduced by switching the valve position, and the hydrogen-water dissolution ratio can be flexibly adjusted; the third one-way valve 117 only allows hydrogen to flow from the electrolysis device into the three-way valve in one direction, preventing high-pressure water or gas in the dissolved gas tank 3 from flowing back into the electrolysis device 11 and causing electrode corrosion; the linkage design of the three-way valve and the one-way valve automatically balances the incoming water and hydrogen flow rates when the hydrogen delivery pressure fluctuates, thereby avoiding pressure imbalance of the gas-liquid two-phase flow in the dissolved gas tank 3.

[0055] like Figure 3 and Figure 5 As shown, the water electrolysis device 11 includes an outer shell 111, an electrolysis electrode 112 and a conductive component 113. An inner chamber is provided in the outer shell 111, and a partition 114 is provided in the middle of the inner chamber. The partition 114 divides the inner chamber into a cathode chamber 1111 and an anode chamber 1112. Electrolysis electrodes 112 are respectively provided in the cathode chamber 1111 and the anode chamber 1112. The electrolysis electrodes 112 are electrically connected to the conductive component 113, and the conductive component 113 is electrically connected to an external power supply.

[0056] Specifically, the interior of the outer shell 111 is divided into an independent cathode chamber 1111 and an anode chamber 1112 by a partition 114 perpendicular to the direction of water flow. A through-type flow channel is provided at the bottom of the two chambers to ensure the circulation of the electrolyte; the two electrolysis electrodes 112 are respectively fixed vertically at the center of the chamber, and their electrode surfaces are parallel to the direction of water flow; the conductive component 113 includes a fixing screw 1131, an embedded nut 1132, and a conductive sheet 1133 respectively embedded in the outer wall of the cathode chamber 1111 and the anode chamber 1112. The fixing screw 1131 is screwed into the blind hole at one end of the embedded nut 1132. The other end is used to connect to the external power supply. A seal 1134 is sleeved on the screw of the fixing screw 1131. The seal 1134 is a rubber ring, which is dynamically compressed by the screw-in depth of the fixing screw 1131. The conductive sheet 1133 is an arc-shaped curved structure. One end of the conductive sheet is crimped with the terminal of the electrolysis electrode 112 through an elastic contact, and the other end is arranged between the nut of the fixing screw 1131 and the seal 1134, thereby realizing an electrolysis circuit consisting of the electrolysis electrode 112, the conductive sheet 1133, the fixing screw 1131, the embedded nut 1132 and the external power supply, and achieving sealing.

[0057] Furthermore, if Figure 4 and Figure 6 As shown, the electrolysis electrode 112 is embedded in the electrode fixing plate 1121 . The surface of the electrolysis electrode 112 is porous. A proton exchange membrane 1122 is provided between the two electrolysis electrodes 112 . A sealing gasket 1123 is provided in the gap between the proton exchange membrane 1122 and the electrode fixing plate 1121 .

[0058] Specifically, the electrolysis electrode 112 is fixed in a preset slot of the electrode fixing plate 1121 by mechanical interlocking or welding, and a honeycomb porous structure is evenly distributed on the electrode surface; the fixing plates of the two electrolysis electrodes 112 are arranged in parallel and opposite to each other, and the proton exchange membrane 1122 is clamped between the two electrode fixing plates 1121, and its edge is bonded to the sealing gasket 1123 by a hot pressing process; the sealing gasket 1123 fills the annular gap between the proton exchange membrane 1122 and the electrode fixing plate 1121, and expands radially under pressure to form an annular sealing belt.

[0059] like Figure 3 As shown, the water inlet of the electrolytic water device 11 is connected to the cathode chamber 1111, and a first one-way valve 115 is provided at the water inlet. A first exhaust valve 118 is provided above the cathode chamber 1111, and the first exhaust valve 118 is connected to the pipeline of the gas dissolving tank 3. A second exhaust valve 119 is provided above the anode chamber 1112, and the second exhaust valve 119 is connected to the external space. The first exhaust valve 118 and the second exhaust valve 119 are located on both sides of the partition 114.

[0060] Specifically, the water inlet of the electrolytic water device 11 is connected to the booster water pump 12 through the water pump inlet connecting pipe 122, and the water inlet is connected to the first one-way valve 115 through a flange, and the opening direction of its valve core points to the cathode chamber 1111. The first one-way valve 115 forces the electrolyte to flow into the cathode chamber 1111 in one direction to prevent the high-pressure water in the dissolved air tank 3 from flowing back and interfering with the electrolytic cell during shutdown; a first exhaust valve 118 pipeline interface is installed on the top of the cathode chamber 1111, which is connected to the inlet of the dissolved air tank 3 through a pressure-resistant hose; a second exhaust valve 119 is installed on the top of the anode chamber 1112, and its outlet end extends to the outside of the outer shell 111; the partition 114 is vertically welded to the inner wall of the outer shell 111, separating the first exhaust valve 118 and the second exhaust valve 119 above the chambers on both sides. Hydrogen is directed into the dissolved gas tank 3 through the first exhaust valve 118, and oxygen is discharged to the open environment through the second exhaust valve 119, eliminating the risk of hydrogen and oxygen mixture explosion. At the same time, the chambers on both sides of the partition 114 are independently exhausted to avoid deformation of the proton exchange membrane 1122 or sealing failure caused by mutual interference of the anode and cathode gas pressures.

[0061] like Figure 4 As shown, a plurality of through holes 1141 are provided at the bottom of the separator 114 , and the through holes 1141 connect the water in the cathode chamber 1111 with the anode chamber 1112 .

[0062] Specifically, multiple rows of circular through holes 1141 are evenly opened along the length direction at the bottom of the partition 114, the axis of the hole is perpendicular to the water flow direction, and the two adjacent rows of through holes 1141 are staggered. The inner walls of the through holes 1141 are polished to form smooth flow channels, so that a continuous water flow channel is formed through the through holes 1141 at the bottom of the cathode chamber 1111 and the anode chamber 1112.

[0063] like Figure 7 As shown, a first fixed bracket 131 is provided at the bottom of the pure water tank 13, and a second fixed bracket 132 is provided near the side. The first fixed bracket 131 is fixedly connected to the bottom of the water heater tank body 4, and the second fixed bracket 132 is fixedly connected to the side of the water heater tank body 4. A water inlet 133 is provided above the second fixed bracket 132, and the water inlet 133 is connected to an external water source. The bottom edge of the connection between the first fixed bracket 131 and the pure water tank 13 is inclined, and the water outlet 134 of the pure water tank 13 is located at the bottom of the pure water tank 13.

[0064] Specifically, the first fixed bracket 131 is an L-shaped steel plate, the bottom plate of which is anchored to the bottom of the water heater body 4 by bolts, and the side plates are welded to the bottom edge of the pure water tank 13 at an inclination angle of less than 90°; the second fixed bracket 132 is a rectangular channel steel, the vertical plate of which is fixed to the side wall of the water heater body 4 by rivets, and the horizontal plate supports the middle part of the side wall of the pure water tank 13; the water inlet 133 is welded above the second fixed bracket 132 with a flange joint, and is connected to the top side wall of the pure water tank 13, and at the same time passes through the outside of the water heater body 4 and is sealed by the pure water tank cover 137; a water outlet 134 is opened at the lowest point along the inclined bottom edge of the bottom of the pure water tank 13, which is led downward through a curved pipe. It uses the gravity self-draining characteristics to ensure that there is no residual water in the pure water tank 13, and to avoid the breeding of microorganisms or the deposition of impurities in the dead water area.

[0065] like Figure 2 As shown, the water heating system 2 further includes a fan 25 , which is located above the heat exchanger 22 , and an air outlet 251 of the fan 25 passes through the water heater housing 4 and communicates with the external space.

[0066] Specifically, fan 25 is secured to the heat exchanger 22 via a bracket, with its axis aligned with the direction of the heat exchanger 22's fins. A wind deflector is welded to the top of the fan 25 housing, extending to the top opening of the water heater housing 4 to form an air outlet 251. Adjustable louvers are installed on the outer edge of air outlet 251 to adjust the direction and flow of exhaust air, and a dust filter is installed inside. Fan 25 draws combustion exhaust and residual heat directly from the heat exchanger 22's surface at high speed, accelerating cooling and preventing metal fatigue or seal degradation caused by localized overheating.

[0067] like Figure 2 As shown, a gas connecting pipe 211 is provided on one side of the burner 21 . The gas connecting pipe 211 passes through the water heater tank 4 and is connected to an external gas source. A gas proportional valve 212 is provided on the gas pipe.

[0068] Specifically, the gas connecting pipe 211 adopts a high-pressure resistant stainless steel pipe, one end of which is connected to the air inlet of the burner 21 through a flange, and the other end passes through the reserved hole on the side wall of the water heater body 4 and is connected to the external gas source pipeline through threaded fasteners; the gas proportional valve 212 is integrated in the middle of the gas connecting pipe 211, and the valve body is fixed to the inner wall of the box through a bracket. Its electrical control interface is connected to the controller 23 through a cable to realize dynamic adjustment of the gas flow. The gas proportional valve 212 accurately adjusts the gas input according to the instructions of the controller 23 to match different combustion load requirements and avoid the risk of incomplete combustion or explosion caused by excessive gas.

[0069] like Figure 2As shown, a water inlet joint 241 is provided at the water inlet of the water pipe to be heated 24, the water inlet joint 241 is connected to the water supply pipe, a pressure relief valve is provided on the water inlet joint 241, and a water flow sensor 242 is provided between the water pipe to be heated 24 and the water inlet joint 241.

[0070] Specifically, the water inlet connector 241 utilizes a flange or quick-connect structure. Its inlet end is threadedly connected to the water supply pipe, and its outlet end is welded to the inlet of the water pipe to be heated 24. A pressure relief valve is integrated into the sidewall of the water inlet connector 241 and serves both the water electrolysis device 11 and the water heater. Its opening threshold is set by a spring preload. The pressure relief valve monitors the inlet water pressure in real time and automatically releases water in the event of water hammer or abnormally high pressure, preventing pipe rupture or damage to the seal 1134. A water flow sensor 242 is secured to the straight pipe section between the water pipe to be heated 24 and the water inlet connector 241 via a clamp. Its signal line passes through a shielded sleeve and connects to the controller 23.

[0071] See also Figures 8 to 10 , the embodiment of the present application also provides a method for controlling a gas water heater that consumes pure water to produce hydrogen-containing water, such as Figure 8-9 As shown, the method includes the following steps S110-S160.

[0072] S110, detecting the water flow rate when the user uses hot water, and determining whether it reaches a preset start threshold;

[0073] S120: If the water flow rate does not reach the start threshold, the water heater is kept off; if it reaches the start threshold, the water inlet temperature is checked to see if it meets the set temperature range;

[0074] S130: When the water inlet temperature meets the requirement, start the gas burner 21 to heat the water flow and detect whether the user has turned on the hydrogen washing function;

[0075] S140: If the hydrogen-containing washing function is turned on, the water electrolysis device 11 is controlled to start, hydrogen is injected into the water flow, and the water level in the water electrolysis device 11 is monitored in real time;

[0076] S150: When the water level is lower than the preset water level threshold, start the booster pump 12 to replenish water to the electrolytic water device 11 until the water level reaches the standard;

[0077] S160 , continuously detecting whether the hydrogen-containing washing function remains turned on; if it is turned off, stopping the water electrolysis device 11 and turning off the gas burner 21 .

[0078] Specifically, in this embodiment, the water flow sensor 242 collects the water flow rate of the water pipe 24 to be heated in real time, and the controller 23 compares the flow signal with the preset start threshold. If the flow rate meets the standard and the water inlet temperature feedback from the temperature sensor is within the set range (such as 10-40°C), the burner 21 ignition program is triggered and the hydrogen washing function switch status on the user operation panel is simultaneously detected. When the hydrogen washing function is turned on, the controller 23 sends a start instruction to the electrolytic water device 11 and monitors the electrolytic cell liquid level through the water level sensor. If the liquid level is below the threshold, the booster water pump 12 is started to replenish water to the set liquid level. During operation, the hydrogen washing function status is continuously polled. When the function is turned off or the flow rate is lower than the threshold, the electrolytic water device 11 and the burner 21 are turned off in turn. This method requires that both the flow rate and the temperature meet the standards before starting heating, which can avoid energy waste caused by low-flow empty burning or ineffective heating at low temperature. At the same time, the user can independently choose whether to enable the hydrogen function. The controller 23 automatically manages the start and stop logic of heating and hydrogen production, without the need for manual intervention in complex parameters.

[0079] Furthermore, in a more specific embodiment, step S150 further includes: when the booster pump 12 replenishes water, it simultaneously detects the working status of the electrodes of the water electrolysis device 11, and triggers an alarm and stops electrolysis if the electrodes are abnormal.

[0080] Specifically, the water replenishment electronic control signal of the booster water pump 12 is linked to the electrode status detection module and triggered. When the water pump starts to replenish water, the current sensor collects the current signal of the electrolysis electrode 112 in real time and compares it with the preset threshold range through the comparator; if the current value continues to deviate from the threshold (such as being lower than the minimum operating current or exceeding the safety upper limit), the control module immediately cuts off the electrolysis power supply and activates the sound and light alarm, and simultaneously sends a shutdown command to the water pump.

[0081] Furthermore, in a more specific embodiment, the preset start threshold is 2.5 L / min.

[0082] Specifically, the preset start threshold is set to a fixed value through the built-in algorithm of the controller 23 and written into the non-volatile memory; when the water flow rate detected in real time by the water flow sensor 242 continues to exceed the threshold for a set time (such as 3 seconds), the controller 23 determines that the start condition is met and triggers the subsequent heating and hydrogen production process; if the flow fluctuation briefly exceeds the threshold but does not meet the time requirement, it is regarded as an invalid signal and no response is given.
