It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0028] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0029] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0030] This application provides a hydrogen-rich water gas-fired heating water heater that can reduce the hardness of heated tap water and balance its acidity and alkalinity. This prevents users from being affected by calcium salts, magnesium salts, and chlorine in the heated tap water, thus avoiding dry, tight, itchy, rough, and dull skin, slowing down skin aging, and improving the user's water experience.

[0031] In one embodiment, such as Figure 1 As shown, a hydrogen-rich water gas-fired heating water heater is provided. The hydrogen-rich water gas-fired heating water heater includes a main heat exchange device 100, a plate heat exchange device 200, and a hydrogen-rich water generator 300.

[0032] The main heat exchange device 100 includes a main heat exchanger 110, a heat exchange inlet pipe 120, and a heat exchange outlet pipe 130. The inlet of the main heat exchanger 110 is connected to the first end of the heat exchange inlet pipe 120, and the second end of the heat exchange inlet pipe 120 is connected to the heating return pipe 400. The outlet of the main heat exchanger 110 is connected to the first end of the heat exchange outlet pipe 130, and the second end of the heat exchange outlet pipe 130 is connected to the heating inlet pipe 900. It can be understood that water in the heating return pipe 400 flows through the heat exchange inlet pipe 120 and enters the main heat exchanger 110 for heat exchange. This process increases the temperature of the water entering the main heat exchanger 110. The water, after heat exchange, flows out through the heat exchange outlet pipe 130 to the heating inlet pipe 900 for heating, and then flows from the heating return pipe 400 back into the heat exchange inlet pipe 120 to re-enter the main heat exchanger 110 for heat exchange.

[0033] In one embodiment, such as Figure 2 As shown, the hydrogen-rich water gas heating water heater also includes a combustion device 1100; the combustion device 1100 is used to provide hot air to the main heat exchanger 110.

[0034] It should be noted that the hydrogen-rich water gas-fired heating water heater has three operating modes: bathing mode, heating mode, and cleaning mode. The control device 500 can freely switch the operating mode of the hydrogen-rich water gas-fired heating water heater according to the user's selection. Specifically, when the hydrogen-rich water gas-fired heating water heater is in bathing mode, it indicates that the user needs to use hot water at the corresponding water point in time; when it is in heating mode, it indicates that the user needs to heat the room; and when it is in automatic cleaning mode, it indicates that the user needs to automatically clean the solid ion membrane 320 in the hydrogen-rich water generator 300.

[0035] The control device 500 is electrically connected to the combustion device 1100 and is used to control the start of the combustion device 1100 in bathing mode or heating mode. It can be understood that when the control device 500 detects that the hydrogen-rich water gas-fired heating water heater is in bathing mode or heating mode, it can promptly control the start of the combustion device 1100, thereby providing hot air to the main heat exchanger 110 in the main heat exchange device 100. Then, water from the heating return water pipe 400 flows through the heat exchange inlet pipe 120 and enters the main heat exchanger 110 to exchange heat with the hot air entering the main heat exchanger 110. This increases the temperature of the water entering the main heat exchanger 110, and the water after heat exchange flows out through the heat exchange outlet pipe 130. Therefore, the convenience of heat exchange in the main heat exchange device 100 of the hydrogen-rich water gas-fired heating water heater is improved.

[0036] In a specific example, the combustion device 1100 includes a burner and a gas regulating valve; wherein, a first end of the gas regulating valve is connected to the burner, and a second end of the gas regulating valve is used to connect to the gas inlet pipe; the burner and the gas regulating valve are electrically connected to a control device 500. When controlling the combustion device 1100, the control device will control the burner to ignite and simultaneously control the gas regulating valve to open to the initial gas flow rate. The above is only a specific example; in actual applications, it can be flexibly configured according to user needs, and no restrictions are imposed here.

[0037] The plate heat exchanger device 200 includes a hot water inlet 201, a cold water outlet 202, a cold water inlet 203, and a hot water outlet 204.

[0038] In this plate heat exchanger 200, the hot water inlet 201 is connected to the second end of the heat exchange outlet pipe 130, and the cold water outlet 202 is connected to the heat exchange inlet pipe 120. The hot water inlet 201 and the cold water outlet 202 are internally connected. The cold water inlet 203 of the plate heat exchanger 200 is used to connect to the cold water inlet pipe 600, and the hot water outlet 204 of the plate heat exchanger 200 is connected to the first inlet 311 of the hydrogen-rich water generator 300. The cold water inlet 203 and the hot water outlet 204 of the plate heat exchanger are internally connected.

[0039] Understandably, the water after heat exchange flows into the hot water inlet 201 of the plate heat exchanger 200 through the heat exchange outlet pipe 130, and into the cold water inlet 203 of the plate heat exchanger 200 through the cold water inlet pipe 600. Simultaneously, the water flowing through the pipe connecting the hot water inlet 201 and the cold water outlet 202 undergoes heat exchange with the water flowing through the pipe connecting the cold water inlet 203 and the hot water outlet 204. This increases the temperature of the water flowing into the cold water inlet 203 through the cold water inlet pipe 600, and the heated water is then output through the hot water outlet 204 to the first inlet 311 of the hydrogen-rich water generator 300. At this point, the temperature of the water flowing into the hot water inlet 201 of the plate heat exchanger 200 is reduced, and the cooled water is output through the cold water outlet 202 to the heat exchange inlet pipe 120, so that the temperature of the incoming water can be increased again through the main heat exchanger 110.

[0040] In a specific example, the plate heat exchanger 200 may be, but is not limited to, a plate heat exchanger. The above is only a specific example. In actual applications, it can be flexibly set according to user needs, and there are no restrictions here.

[0041] The hydrogen-rich water generator 300 receives water flowing out of the hot water outlet 204 of the plate heat exchanger 200 through the first inlet 311 of the hydrogen-rich water generator 300, filters it, and then outputs hydrogen-rich water from the first outlet 312 of the hydrogen-rich water generator 300.

[0042] It should be noted that when the main heat exchanger 100 is in operation, the water flowing out of the hot water outlet 204 of the plate heat exchanger 200 undergoes heat exchange, resulting in a temperature increase. Therefore, the temperature of the hydrogen-rich water output from the first outlet 312 of the hydrogen-rich water generator 300 is higher than that of the water flowing into the cold water inlet 203 of the plate heat exchanger 200 from the cold water inlet pipe 600. When the main heat exchanger 100 is not in operation, the water flowing out of the hot water outlet 204 of the plate heat exchanger 200 does not undergo heat exchange, and its temperature remains unchanged. Therefore, the temperature of the hydrogen-rich water output from the first outlet 312 of the hydrogen-rich water generator 300 is not significantly different from that of the water flowing into the cold water inlet 203 of the plate heat exchanger 200 from the cold water inlet pipe 600.

[0043] Based on this, the hydrogen-rich water gas heating water heater described above can reduce the hardness of tap water after it has been heated by the plate heat exchanger 200, and also adjust the acidity and alkalinity of the heated tap water. This avoids the effects of calcium salts, magnesium salts, and chlorine in the water on users when using the heated tap water, thus preventing users from experiencing dry, tight, itchy, rough, and dull skin, slowing down the aging process of the user's skin, and improving the user's water experience.

[0044] In one embodiment, such as Figure 3 As shown, the hydrogen-rich water generator 300 includes a housing 310, a solid ion membrane 320, an anode electrolysis plate 330, and a cathode electrolysis plate 340.

[0045] The housing 310 is used to form the electrolysis chamber. In a specific example, the housing 310 can be in the shape of a cube or a cuboid. The above is only a specific example. In actual applications, the specific material and shape of the housing 310 can be flexibly set according to user needs, and there are no restrictions here.

[0046] A solid ion exchange membrane 320 is disposed inside the housing 310, and divides the electrolysis chamber into a first sub-chamber and a second sub-chamber. A first water inlet 311 is provided at the housing 310 corresponding to the first sub-chamber to introduce water flowing out of the hot water outlet 204 into the first sub-chamber. A first water outlet 312 is provided at the housing 310 corresponding to the second sub-chamber to output hydrogen-rich water.

[0047] In a specific example, the solid ion exchange membrane 320 may be, but is not limited to, a semi-permeable membrane; the first inlet 311 may be, but is not limited to, located on the side of the housing 310 corresponding to the first compartment; and the first outlet 312 may be, but is not limited to, located on the bottom or side of the housing 310 corresponding to the second compartment. The above are merely specific examples; in actual applications, the configuration can be flexibly adjusted according to user needs, and no restrictions are imposed here.

[0048] In one embodiment, such as Figure 3 As shown, the solid ion membrane 320 is inclinedly arranged inside the housing 310, which can increase the installation area of ​​the solid ion membrane 320, improve the filtration efficiency of the solid ion membrane in the hydrogen-rich water generator 300, and improve the convenience of the hydrogen-rich water generator 300.

[0049] The anode electrolysis plate 330 is disposed in the first compartment, and the cathode electrolysis plate 340 is disposed in the second compartment.

[0050] Understandably, the hydrogen-rich water generator 300 receives water flowing from the hot water outlet 204 of the plate heat exchanger 200 through the first water inlet 311 opened at the shell 310 corresponding to the first compartment, and introduces the water into the first compartment. At this time, the water in the first compartment undergoes an electrolytic reaction due to the anode electrolysis plate 330 and the cathode electrolysis plate 340, thereby generating OH-. - H + H2 and O2. Because solid ion-exchange membranes can prevent OH-... - And O2, but the pores on the solid ion membrane can allow H to pass through. + H2 and H2O, so a H-rich environment is formed in the second compartment. +The hydrogen-rich water, which is produced by reacting H2 with H2, is output through the first outlet 312 of the hydrogen-rich water generator 300. Therefore, the hydrogen-rich water generator 300 can quickly produce hydrogen-rich water, improving the convenience of hydrogen-rich water gas heating water heaters.

[0051] In one embodiment, such as Figure 3 As shown, a drain port 314 is provided at the housing 310 corresponding to the first compartment; a second water inlet 313 is provided at the housing 310 corresponding to the second compartment to guide the water flowing out of the hot water outlet 204 into the second compartment.

[0052] In one specific example, the drain port 314 may, but is not limited to, be located at the bottom of the housing 310 corresponding to the first compartment, which is beneficial to improving the drainage efficiency of the drain port 314. The above is only a specific example, and in actual applications, it can be flexibly set according to user needs, and there are no restrictions here.

[0053] The hydrogen-rich water gas-fired heating water heater also includes a first three-way solenoid valve 700 and a control device 500. The first end of the first three-way solenoid valve 700 is connected to the hot water outlet 204, the second end is connected to the first inlet 311, and the third end is connected to the second inlet 313. The control device 500 is electrically connected to the first three-way solenoid valve 700, the anode electrolysis plate 330, and the cathode electrolysis plate 340. In automatic cleaning mode, it controls the polarity switching of the anode electrolysis plate 330 and the cathode electrolysis plate 340, controls the second end of the first three-way solenoid valve 700 to switch from a conducting state to a closed state, and controls the third end of the first three-way solenoid valve 700 to switch from a closed state to a conducting state, so that the dirt in the first compartment is discharged through the drain port 314.

[0054] Understandably, when the hydrogen-rich water gas heating water heater is in shower mode, the control device 500 controls the second end of the first three-way solenoid valve 700 to be in a conducting state and controls the third end of the first three-way solenoid valve 700 to be in a cut-off state. This allows the water flowing from the hot water outlet 204 of the plate heat exchanger 200 to be introduced into the first compartment through the first inlet 311, and not into the second compartment through the second inlet 313. At this time, the water in the first compartment undergoes an electrolytic reaction due to the anode electrolysis plate 330 and the cathode electrolysis plate 340, thereby generating OH-. - H + H2 and O2. Because solid ion-exchange membranes can prevent OH-... - And O2, but the pores on the solid ion membrane can allow H to pass through. + H2 and H2O, so a H-rich environment is formed in the second compartment. + The hydrogen-rich water is produced by reacting H2 with H2 and then output through the first outlet 312 of the hydrogen-rich water generator 300.

[0055] When the hydrogen-rich water gas heating water heater is in automatic cleaning mode, the control device 500 controls the second end of the first three-way solenoid valve 700 to switch from the conducting state to the cut-off state, and controls the third end of the first three-way solenoid valve 700 to switch from the cut-off state to the conducting state. This allows the water flowing from the hot water outlet 204 of the plate heat exchanger 200 to be introduced into the second compartment through the second inlet 313, and will not be introduced into the first compartment through the first inlet 311. At the same time, the control device 500 controls the anode electrolysis plate 330 and the cathode electrolysis plate 340 to switch polarities. At this time, the water in the second compartment continues to undergo electrolysis reaction due to the switching polarities of the anode electrolysis plate 330 and the cathode electrolysis plate 340. As a result, the solid ion membrane 320, the anode electrolysis plate 330 before the polarity switch, and the calcium and magnesium salts in the first compartment automatically detach and are discharged from the drain outlet 314 along with the water in the first compartment, thus realizing the automatic cleaning function of the hydrogen-rich water generator 300.

[0056] In one embodiment, such as Figure 3 As shown, the solid ion membrane 320 is inclinedly disposed inside the housing 310. The solid ion membrane 320 has a first end and a second end connected to the housing 310. The first end is located at a higher position than the second end. The second inlet 313 is disposed close to the first end.

[0057] In the automatic cleaning mode of the hydrogen-rich water gas heating water heater, the control device 500 controls the second end of the first three-way solenoid valve 700 to switch from the conducting state to the cut-off state, and controls the third end of the first three-way solenoid valve 700 to switch from the cut-off state to the conducting state, thereby realizing the automatic cleaning function of the hydrogen-rich water generator 300. Since the solid ion membrane 320 is inclinedly arranged inside the housing 310, and the second inlet 313 is located close to the first end point, water flowing from the hot water outlet 204 of the plate heat exchanger 200 is introduced into the second chamber through the higher-positioned second inlet 313, further flushing away the dirt on the solid ion membrane 320 and improving the efficiency of automatic cleaning.

[0058] In one embodiment, such as Figure 3 As shown, the drain outlet 31 is located near the second end point. Since the second end point is lower than the first end point, it is beneficial for the water containing dirt in the first compartment to be discharged quickly from the drain outlet 314 in the automatic cleaning mode, which improves the drainage efficiency of the hydrogen-rich water generator 300.

[0059] In this embodiment, the polarity switching of the anode electrolysis plate 330 and the cathode electrolysis plate 340 is controlled by the control device 500, and the first three-way solenoid valve 700 is controlled to switch the water inlet of the hydrogen-rich water generator 300. This realizes the automatic cleaning of the hydrogen-rich water generator 300, reduces scale in bathroom pipes and inhibits bacterial growth, extends the service life of the hydrogen-rich water generator 300 and bathroom pipes, and improves the health of users' water use.

[0060] In one embodiment, such as Figure 3 As shown, the hydrogen-rich water generator also includes a drain pipe 350 and a two-way solenoid valve 360.

[0061] The system includes a drain pipe 350 connected to a drain outlet 314, and a two-way solenoid valve 360 ​​installed within the drain pipe 350. A control device 500 is electrically connected to the two-way solenoid valve 360 ​​and, in automatic cleaning mode, controls the valve to switch from a closed to a conducting state, allowing dirt in the first chamber to flow from the drain outlet 314 through the drain pipe 350 and be discharged. It should be noted that in bathing and heating modes, the control device 500 keeps the two-way solenoid valve 360 ​​in the closed state. This improves the convenience of the hydrogen-rich water generator 300.

[0062] In one embodiment, such as Figure 3 As shown, an exhaust port 315 is provided at the housing 310 corresponding to the first compartment. Because the water in the first compartment undergoes an electrolytic reaction between the anode electrolysis plate 330 and the cathode electrolysis plate 340, OH- is generated. - H + H2 and O2, however, solid ion membranes can prevent OH- - The hydrogen and O2 are discharged through exhaust port 315, thus improving the convenience of the hydrogen-rich water generator 300.

[0063] In a specific example, the exhaust port 315 may be located on the top of the housing 310 corresponding to the first compartment, which is beneficial to improving the efficiency of the hydrogen-rich water generator 300 in discharging exhaust gas. The above is only a specific example, and in actual applications, it can be flexibly set according to user needs, and there are no restrictions here.

[0064] In one embodiment, the hydrogen-rich water generator 300 also includes an exhaust valve. The exhaust valve is located at the exhaust port 315. A control device 500 is electrically connected to the exhaust valve and controls it to be open when the hydrogen-rich water gas-fired water heater is in bathing mode. Furthermore, the control device 500 controls the exhaust valve to be closed when the hydrogen-rich water gas-fired water heater is in heating mode or automatic cleaning mode. Therefore, the convenience of the hydrogen-rich water generator 300 is improved.

[0065] In one embodiment, such as Figure 2 As shown, the hydrogen-rich water gas heating water heater also includes a flue gas exhaust device 1200. The flue gas exhaust device is used to exhaust air from the main heat exchange unit 100.

[0066] The control device 500 is electrically connected to the exhaust device 1200 and is used to control the start of the exhaust device 1200 in either bathing or heating mode. This improves the convenience of hydrogen-rich water gas-fired heating water heaters.

[0067] In one embodiment, such as Figure 2 As shown, the hydrogen-rich water gas heating water heater also includes a second three-way solenoid valve 800.

[0068] The first end of the second three-way solenoid valve 800 is connected to the heating water inlet pipe 900, the second end of the second three-way solenoid valve 800 is connected to the second end of the heat exchange water outlet pipe 130, and the third end of the second three-way solenoid valve 800 is connected to the hot water inlet 201.

[0069] The control device 500 is electrically connected to the second three-way solenoid valve 800. In bathing mode, it controls the first end of the second three-way solenoid valve 800 to be in a closed state and the third end to be in a conducting state. This ensures that water in the heat exchange outlet pipe 130 flows into the plate heat exchanger 300 only through the hot water inlet 201 and not into the heating inlet pipe 900. This raises the temperature of the water flowing into the cold water inlet pipe 600 through the cold water inlet 203, enabling the output of hydrogen-rich water through the first outlet 312 of the hydrogen-rich water generator 300. Furthermore, in heating mode, the control device 500 also controls the first end of the second three-way solenoid valve 800 to be in a conducting state and the third end to be in a closed state. This ensures that water in the heat exchange outlet pipe 130 flows only into the heating inlet pipe 900 for heating and does not flow into the plate heat exchanger 300 through the hot water inlet 201. Therefore, it improves the convenience of hydrogen-rich water gas heating water heaters.

[0070] In one embodiment, such as Figure 2 As shown, the hydrogen-rich water gas heating water heater also includes a circulation pump 1000.

[0071] The circulating pump 1000 is installed on the heat exchange inlet pipe 120. The control device 500 is electrically connected to the circulating pump 1000 and is used to control the starting of the circulating pump 1000 in the bathing mode or the heating mode, so as to realize the circulation of water in the hydrogen-rich water gas heating water heater and improve the convenience of the hydrogen-rich water gas heating water heater.
