[0028] Hydrogen-rich water refers to drinking water formed by dissolving additional hydrogen in water through physical or chemical methods. For example, using an electrolysis device to decompose water into hydrogen and oxygen, and the hydrogen dissolves in the water to form hydrogen-rich water. Since hydrogen-rich water contains a relatively high concentration of molecular hydrogen (H 2 ), it has potential health-promoting effects and has thus received extensive attention.

[0029] The existing technologies for preparing hydrogen-rich water can be generally divided into three types: The first type: A hydrogen-rich water generating device adopting a fixed power mode. However, due to the inability to adapt to changes in water flow, water temperature, and conductivity in the fixed power mode, it is impossible to stably prepare hydrogen-rich water.

[0030] The second type: A hydrogen-rich water generating device that adjusts the power to control hydrogen generation according to the water flow rate. However, under high-temperature conditions, the water temperature and the hydrogen solubility in hydrogen-rich water are negatively correlated, and the rapid escape of hydrogen bubbles will result in a relatively low effective dissolution rate in the water.

[0031] The third type: A hydrogen-rich water generating device that improves the hydrogen solubility through mechanical structure design. However, designing complex mechanical structures (such as stirrers, ultrasonic generators, or micro-nano bubble generators) will increase the complexity of the system and the manufacturing cost.

[0032] To solve the above problems in the existing technologies, the present application provides a control method for preparing hydrogen-rich water based on a water heater, which can effectively prevent the problem that the surface temperature of the electrode rises due to excessive current, accelerating the escape of hydrogen bubbles and then reducing the hydrogen solubility in water, thereby improving the stability of hydrogen-rich water preparation and the hydrogen solubility.

[0033] The control device for preparing hydrogen-rich water by the water heater provided in the present application includes a water heater and an electrolysis device, and the water outlet of the water heater is connected to the electrolysis device.

[0034] AsFigure 1 As shown in the figure, a Hall flowmeter 30 is provided at the water inlet of the water heater 10 for real-time detection of the water inlet flow rate of the water heater 10. A temperature sensor 40 is provided at the water inlet of the electrolysis device 20 for real-time detection of the water inlet temperature of the electrolysis device 20. The electrolysis device 20 is further provided with a conductivity probe 50 for real-time detection of the conductivity of the water in the electrolysis device 20.

[0035] Referring to the first embodiment of a control method for preparing hydrogen-rich water based on a water heater provided in the present application, the method includes the following steps: Step 110: Obtain the current value generated by the electrolysis device during the preparation of hydrogen-rich water.

[0036] Step 120: Determine whether the current value is greater than a preset safe current.

[0037] Step 130: If the current value is greater than the preset safe current, adjust the current value to the preset safe current.

[0038] Among them, the preset safe current can be artificially set and adjusted according to actual situations (such as electrode materials, conductivity, etc.). For example, it can be 1.5A, 1.6A, etc. The present application does not make any limitations here.

[0039] This embodiment can effectively prevent the problem that the temperature of the electrode surface rises due to excessive current, accelerating the escape of hydrogen, and then reducing the solubility of hydrogen in water by real-time monitoring of the current value generated by the electrolysis device and comparing it with the preset safe current, thereby improving the stability of hydrogen-rich water preparation and the solubility of hydrogen.

[0040] Since the preset safe current can avoid personal injury to users in case of accidental electric leakage, and this preset safe current can prevent the temperature of the electrode surface from rising due to excessive current, therefore, adjusting the current value to the preset safe current can ensure the safety of user use and the stability of hydrogen production.

[0041] In addition, increasing the current can accelerate the electrolysis speed, thereby increasing the volume of hydrogen gas generated per unit time. Therefore, when the current value is greater than the preset safe current, after reducing the current value to the preset safe current and keeping it stable, no longer continue to reduce the current value, which can maximize the solubility of hydrogen while ensuring the safety of user use.

[0042] Referring to the second embodiment of a control method for preparing hydrogen-rich water based on a water heater provided in the embodiments of the present application, the method includes the following steps: Step 210: Obtain the current value generated by the electrolysis device during the preparation of hydrogen-rich water.

[0043] Step 220: Determine whether the current value is greater than a preset safe current.

[0044] Step 230: If the current value is greater than the preset safe current, adjust the current value to the preset safe current.

[0045] Among them, adjusting the current value to the preset safe current in step 230 may include the following steps: Step 231: Obtain a pulse width modulation signal.

[0046] Step 232: Based on the pulse width modulation signal, adjust the current value to the preset safe current.

[0047] Refer to Figure 2 , a third embodiment of a control method for preparing hydrogen-rich water based on a water heater provided by this application, the method includes the following steps: Step 310: Obtain the inlet water temperature, inlet water flow rate, and conductivity of water of the electrolysis device.

[0048] Step 320: Based on the inlet water temperature, the inlet water flow rate, and the conductivity, obtain an optimal current coefficient.

[0049] Among them, the inlet water flow rate of the electrolysis device is the same as the inlet water flow rate of the water heater, and can be detected according to Figure 1 the Hall flowmeter 30 in

[0050] In some embodiments, the calculation of the optimal current coefficient can refer to the following formula 1: , formula 1.

[0051] Among them, is the optimal current coefficient, is the inlet water temperature, is the hydrogen solubility in water corresponding to the case where the inlet water temperature is , is the conductivity of water, is the inlet water flow rate.

[0052] Among them, the calculation of the hydrogen solubility can refer to the following formula 2: , formula 2.

[0053] Among them, is the standard temperature, generally 25°, is the hydrogen solubility in water corresponding to the case where the standard temperature is .

[0054] Step 330: Based on the optimal current coefficient, obtain the current value generated by the electrolysis device during the preparation of hydrogen-rich water.

[0055] Among them, the current value I generated by the electrolysis device during the preparation of hydrogen-rich water can be calculated using the following formula 3: , Formula 3.

[0056] Among them, is the initial current value of the electrolysis device before the start of the electrolysis process.

[0057] Step 340: Determine whether the current value is greater than a preset safe current.

[0058] Step 350: If the current value is greater than the preset safe current, adjust the current value to the preset safe current.

[0059] Refer to Figure 3 , the fourth embodiment of a control method for preparing hydrogen-rich water based on a water heater provided in the present application, the method includes the following steps: Step 410: Obtain the hydrogen concentration generated by the electrolysis device during the preparation of hydrogen-rich water.

[0060] Step 420: Determine whether the hydrogen concentration is within a preset optimal concentration range. If the hydrogen concentration is within the preset optimal concentration range, then determine whether the current value is greater than a preset safe current.

[0061] Among them, the preset optimal concentration range can be [C 1 , C 2 .

[0062] Step 430: If the current value is greater than the preset safe current, adjust the current value to the preset safe current.

[0063] In this way, by first determining whether the hydrogen concentration is within the preset optimal concentration range, the hydrogen concentration can be made to be within the preset optimal concentration range, thereby ensuring a relatively high hydrogen content in the hydrogen-rich water and improving the hydrogen solubility.

[0064] In some possible implementation manners, determining whether the hydrogen concentration is within the preset optimal concentration range further includes: if the hydrogen concentration is not within the preset optimal concentration range, then adjust the power of the electrolysis device to a preset target power, and then execute the step of determining whether the current value is greater than the preset safe current.

[0065] Among them, the hydrogen concentration corresponding to the preset target power is within the preset optimal concentration range.

[0066] In some embodiments, it is possible to determine whether to stop power adjustment through the following Formulas 4 and 5.

[0067] In some embodiments, the calculation of the preset target power can adopt Formula 4: , Formula 4.

[0068] Wherein, is the preset target power, is the target current value corresponding to the optimal hydrogen concentration, is the voltage of the electrolysis device.

[0069] In some embodiments, the calculation of the target current value can adopt Formula 5: , Formula 5.

[0070] Wherein, is the optimal hydrogen concentration, which can be obtained by collecting through a sensor, , , n is the error value, and n can be set by the user according to the actual situation. That is to say, it is possible to obtain the preset optimal concentration range [C , C 1 , C 2 .

[0071] is the conductivity of water, represents the exponential factor of the non-linear relationship between current and hydrogen concentration, is the ratio of the actual dissolved amount of hydrogen in the electrolysis device to the theoretical hydrogen production amount.

[0072] Exemplarily, when the inlet water flow rate is fixed, the influence of the inlet water temperature on the hydrogen concentration can be referred to Figure 4 .

[0073] Specifically, under the condition that the inlet water flow rate is fixed, when the hydrogen concentration C < C 1 , a compensation program can be triggered to control the voltage of the electrolysis device to be increased to 24V (under normal working conditions, the voltage is 12V), thereby increasing the power, and synchronously reducing the inlet water flow rate to 80% of the initial value, so that the hydrogen concentration prepared by the electrolysis device can be adjusted within the preset optimal concentration range.

[0074] Refer to Figure 5 , the fifth embodiment of a control method for preparing hydrogen-rich water based on a water heater provided by an embodiment of the present application, the method includes the following steps: Step 510: Obtain the hydrogen dissolution rate generated during the process of the electrolysis device preparing hydrogen-rich water.

[0075] Step 520: Determine whether the hydrogen dissolution rate is within a preset optimal dissolution rate range. If the hydrogen dissolution rate is within the preset optimal hydrogen dissolution rate range, then determine whether the current value is greater than a preset safe current.

[0076] Among them, the preset optimal dissolution rate range can be [η 1 , η 2 .

[0077] Step 530: If the current value is greater than the preset safe current, then adjust the current value to the preset safe current.

[0078] In this way, by first determining whether the hydrogen dissolution rate is within the preset optimal dissolution rate range, the hydrogen dissolution rate can be made within the preset optimal dissolution rate range, thereby ensuring a relatively high hydrogen content in the hydrogen-rich water and improving the hydrogen solubility.

[0079] In some possible implementation manners, when determining whether the hydrogen dissolution rate is within the preset optimal hydrogen dissolution rate range, it further includes: if the hydrogen dissolution rate is not within the preset optimal hydrogen dissolution rate range, then after adjusting the hydrogen dissolution rate to the preset optimal hydrogen dissolution rate range, perform the step of determining whether the current value is greater than the preset safe current.

[0080] In some possible implementation manners, before adjusting the hydrogen dissolution rate to the preset optimal hydrogen dissolution rate range, the method further includes: obtaining the initial current value, initial water temperature, and initial water flow rate of the electrolysis device before electrolysis.

[0081] Then, adjusting the hydrogen dissolution rate to the preset optimal hydrogen dissolution rate range includes: based on the initial current value, the initial water temperature, and the initial water flow rate, adjusting the hydrogen dissolution rate until the hydrogen dissolution rate is within the preset optimal hydrogen dissolution rate range.

[0082] Among them, the hydrogen dissolution rate can be adjusted according to the following formula 6.

[0083] η = , formula 6.

[0084] Among them, η is the dissolution rate of hydrogen in the electrolysis device, that is, the hydrogen dissolution rate, is the current adjustment coefficient, is the temperature adjustment coefficient, is the water flow adjustment coefficient, is the initial current value of the electrolysis device before electrolysis, is the initial water temperature of the electrolysis device before electrolysis, is the initial water flow rate of the electrolysis device before electrolysis.

[0085] Since temperature adjustment and flow rate adjustment can easily affect the user's bathing experience, in some embodiments, the current can be preferentially adjusted. When the current is adjusted to the limit and still does not meet the determination condition of η, the coefficient of the current is fixed, and then the inlet water flow rate and the inlet water temperature are adjusted.
