Through electrolysis, the cathode of the electrolyzed water module produces strongly alkaline water, and the anode produces strongly acidic water.

[0003] Electrolyzed water modules are generally set with a certain lifespan at the time of shipment, and in conventional technology, the need for replacement is often determined based on the amount of time the electrolyzed water module has been used. However, in actual use, the lifespan of the electrolyzed water module varies somewhat depending on the water quality, and the water quality has some effect on the lifespan of the electrolyzed water module. Therefore, determining whether the electrolyzed water module needs replacement based on the amount of time may lead to erroneous results and may affect the sterilization effect of the electrolyzed water module.

[0021] Hereinafter, the technical aspects of the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the present invention, and do not describe all the embodiments. It is clear that all other embodiments that can be implemented by those skilled in the art based on the embodiments of the present invention without any creative efforts are included in the protection scope of the present invention.

[0022] In describing the present invention, the terms "comprise," "include," or any other variation thereof, are intended to cover a non-exclusive inclusion, and thus a process, method, article, or apparatus comprising a series of elements is intended to include not only those elements, but also other elements not expressly listed or inherent in such process, method, article, or apparatus. Unless further limited, an element qualified by the phrase "comprises a..." does not exclude the situation where other similar elements are present in the process, method, article, or apparatus that comprises said element.

[0023] In describing the present invention, the terms "first" and "second" are for descriptive purposes only and should not be understood as expressing or implying any relative importance.

[0024] As shown in FIG. 1, the electrolytic water module life monitoring method of the present invention includes: An electrical signal detection step S101 of detecting an electrical signal generated in the electrolyzed water module and including a current or a voltage; The method includes a life detection step S102 that suggests replacing the electrolytic water module when it is detected that the electrical signal has reached a first predetermined electrical signal or that the usage time corresponding to the electrical signal has reached a predetermined usage time of the electrolytic water module.

[0025] The following description will be given taking the detection of the current generated in the electrolyzed water module as an example.

[0026] Specifically, the execution body of the method of the present invention includes an MCU controller or other controllers that can execute the above steps.

[0027] Specifically, the current generated by the electrolyzed water module is collected via the I / O interface of the MCU controller, and a decision is made based on a first predetermined current and usage time preset in the MCU controller to recommend immediate replacement of the electrolyzed water module. Even if the electrolyzed water module's sterilization effect declines or becomes insufficient, the module continues to be used, preventing the module from failing to achieve its sterilization effect. There are two current-based lifespan detection methods. One is to empirically set a first predetermined current and recommend replacement of the electrolyzed water module when it is detected that the current has reached the first predetermined current. Another method is to predict usage time using a linear model of current and usage time, and recommend replacement of the electrolyzed water module when it is detected that the usage time corresponding to the current has reached the preset usage time of the electrolyzed water module.

[0028] If the condition for replacement is met first by either method, a higher sterilization effect can be achieved by suggesting replacement of the electrolyzed water module. The first predetermined current can be determined by measuring the electrolysis current until several electrolyzed water modules fail and averaging several electrode currents.

[0029] The method further includes recording the electrolysis current / electrolysis voltage for each time period for a first predetermined current, recording the difference between the electrolysis current / electrolysis voltage for two adjacent times, determining whether the difference is greater than the predetermined current / voltage, and if so, determining that the electrolysis module is faulty and recommending replacement of the electrolyzed water module. Alternatively, the method calculates the rate of change of the electrolysis current / electrolysis voltage from the difference and determines whether it is greater than a preset rate of change of the current / voltage to determine whether the electrolysis current / electrolysis voltage has changed significantly, and if so, determining that the electrolysis module is faulty and recommending replacement of the electrolyzed water module.

[0030] In addition to the above-mentioned lifespan detection based on the electric current, the present invention also includes lifespan calculation based on statistics of the usage time. Detecting the usage time of the electrolyzed water module; The method further includes a step of suggesting replacement of the electrolyzed water module when it is detected that the usage time has reached the set lifespan.

[0031] By combining the current-based and time-based lifespan detection methods, the electrolyzed water module is recommended for replacement when either of the two methods reaches the recommended condition first, achieving a better sterilization effect. Furthermore, using both methods has the added benefit of ensuring detection by the other if one method fails to detect.

[0032] The above-mentioned predetermined usage time may be set equal to the life time set at the time of shipment of the electrolytic water module, or may be set according to actual demand, and this embodiment is not limited thereto.

[0033] In this embodiment, as shown in FIG. 2, the current generated by the electrolytic water module is linearly related to the usage time of the electrolytic water module, specifically, is a linear function, and the equation is as follows: T use = aI cur + b

[0034] Among them, T use represents the usage time, and I cur represents the current instantly generated by the electrolytic water module, a represents the gradient, and b is the constant term.

[0035] Specifically, through extensive experimental measurements, it was determined that there is a linear relationship between the current generated by the electrolytic water module and the usage time of the electrolytic water module, and a fitting algorithm was used to fit the slope a. Figure 2 shows that the slope a is positive.

[0036] In one embodiment, the method for obtaining the constant term b in the linear equation is as follows:

[0037] Within a first predetermined time period after the start of use of the electrolytic water module, the current generated by the electrolytic water module is continuously sampled, the current corresponding to each time is recorded, and this is given to the constant term b as a reference value.

[0038] Specifically, the reference value is the average value of the current corresponding to each time point within the first predetermined time, or the current corresponding to the last time point within the first predetermined time. Of course, other current values ​​within the first predetermined time, or current values ​​obtained by other combination processing, may also be used as the reference value. Specifically, it may be set according to actual needs, and is not limited to this embodiment.

[0039] In this embodiment, the method further includes detecting the current water quality based on the current generated in the electrolyzed water module. Specifically, JPEG0007783225000002.jpg26170, where Q represents the current water quality value, T1 represents a predetermined period, and I1 represents the current generated during the predetermined period.

[0040] Determining the current water quality through current detection over a certain period of time ensures the accuracy of the detected water quality. The gases dissolved in water are primarily oxygen and carbon dioxide, and the dissolved ions are primarily potassium, sodium, calcium, magnesium, chloride, sulfate, bicarbonate, carbonate, and other ions. Experiments have shown that when the water quality is good, the dissolved ion concentrations in the water are relatively balanced, and the detected current approaches 1A. When the water quality is poor, the dissolved ion concentrations in the water are relatively unbalanced, and the detected current becomes larger.

[0041] Specifically, the method for monitoring the lifespan of an electrolyzed water module further includes a step of stopping and / or displaying a notification when it is detected that the current water quality value has reached a predetermined water quality value. The current water quality is detected based on the magnitude of the detected current generated by the electrolyzed water module. When the current water quality value reaches a predetermined water quality value, it is determined that the water quality is poor and a notification to that effect can be displayed. Based on the displayed information, the user can investigate the cause of the poor water quality, temporarily stop the water flow, or stop the power supply to the electrolyzed water module. By controlling the power supply and cutoff of the electrolyzed water module depending on the quality of the water and powering it on only after the water quality has improved, the useful life of the electrolyzed water module can be extended.

[0042] Furthermore, before detecting the current generated by the electrolytic water module, the method further includes a step of detecting whether the current generated by the electrolytic water module is stable within a second predetermined time, and if it is not stable, the life detection step is not performed.

[0043] Detecting whether the current generated by the electrolytic water module within the second specified time is stable specifically involves determining whether the average value of the current variation at each time within the second specified time exceeds a specified variation value, and if it does, determining that it is unstable, and if it does not, determining that it is stable.

[0044] Since the water quality also has a corresponding effect on the current, in the present invention, the accuracy of the test results can be ensured by starting the life test once the water quality has stabilized.

[0045] Furthermore, the method further includes a step of determining whether the time that water has flowed through the electrolytic water module has reached a first predetermined time before detecting the current generated in the electrolytic water module, and if so, executing a life detection step, and if not, not executing the life detection step.

[0046] When water is first used, the electrolytic water module may be unstable, so lifespan detection can be started after a first predetermined time from the start of water flow to ensure the accuracy of the detection results. The current during the first predetermined time can be used as a reference value to compare with the current generated thereafter, and this is the constant term b in the linear equation.

[0047] Based on the above, in one embodiment, a detailed flowchart of the electrolytic water module life monitoring method of the present invention is shown in FIG. 4, and specifically, starting the electrolyzed water module; a user pouring water; A step of determining whether the water flow time is longer than a first predetermined time, and if it is longer, performing a subsequent electrolytic water module life detection step (detecting the current of the electrolytic water module); if not, not performing electrolytic water module life detection, and recording the current value as a reference value, or not performing any operation; Detecting the current of the electrolyzed water module; A step of determining whether the current of the electrolyzed water module is stable, and if it is stable, executing the subsequent electrolyzed water module life detection step (the current value may then be recorded and used as a reference value), and if it is not stable, not performing electrolyzed water module life detection; A step of starting electrolyzed water module life detection; The method includes a step of determining whether the current is greater than a first predetermined current or whether the usage time corresponding to the current is greater than the predetermined usage time of the electrolytic water module, and if either condition is met, suggesting to the user that the electrolytic water module be replaced.

[0048] As shown in Figure 5, the electrolytic water module life monitoring system an electrical signal detection module 501 for detecting an electrical signal generated in the electrolyzed water module and including a current or voltage; and a life detection module 502 for suggesting replacement of the electrolytic water module when it detects that the electrical signal has reached a first predetermined electrical signal or that the usage time corresponding to the electrical signal has reached a predetermined usage time of the electrolytic water module.

[0049] Specifically, the electrical signal detection module 501 and the life detection module 502 can be realized by an MCU control circuit or other control circuits.

[0050] Figure 6 shows a schematic diagram of the connection of an electrolyzed water module and monitoring system according to an embodiment of the present invention. The positive terminal of the electrolyzed water module is connected to the positive terminal of the power supply, and the negative terminal of the electrolyzed water module is connected to the MCU control circuit. The symbols in the diagram are represented as follows: Symbol 1 is the electrolyzed water module, Symbol 2 is the positive terminal of the electrolyzed water module, Symbol 3 is the negative terminal of the electrolyzed water module, Symbol 4 is the MCU control circuit, Symbol 5 is the positive terminal of the power supply, Symbol 6 is the negative terminal of the power supply, Symbol 7 is the water inlet of the electrolyzed water module, and Symbol 8 is the water outlet of the electrolyzed water module.

[0051] Specifically, the MCU control circuit includes an MCU controller and a voltage conversion circuit, as shown in Fig. 7. The MCU controller determines the collected current of ELE_Level_1 as the current generated by the electrolyzed water module.

[0052] The relationship between the measured electrolysis current and the measured electrolysis voltage is I=(V23*R34) / (R32+R34), where V23 can be understood as the voltage signal generated by the electrolytic water module, and I can be understood as the current signal generated by the electrolytic water module.

[0053] In addition, other functions of a specific electrolytic water module lifespan research system for realizing the same electrolytic water module lifespan monitoring method will not be described in this embodiment. The above is only a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto. Those skilled in the art can make equivalent substitutions or modifications within the technical scope of the present invention based on the technical idea and improved ideas of the present invention, and these should also be included in the scope of protection of the present invention.
