Description

Technical Field

[0001] The present invention relates to the technical field of electrolyzed water modules, and particularly to a method and apparatus for polarity inversion equilibrium of an electrolyzed water module and an electrolyzed water system.

Background Art

[0002] Electrolyzed water is sterilized water with a certain acidity / alkalinity and oxidation-reduction property generated by electrolyzing water with an electrolyzed water module. By electrolysis, strongly alkaline water is generated at the negative electrode of the electrolyzed water module, and strongly acidic water is generated at the positive electrode. If the electrolyzed water module is left with a certain polarity for a long time, scale will form inside the module, and bacteria will grow inside the module, affecting the sterilization effect. The strength of acidity / alkalinity can be adjusted by adjusting the electrolysis time, current intensity, and salt concentration, but frequently inverting the polarity of the electrolyzed water module also affects the lifespan of the electrolyzed water module. As described above, if the polarity inversion of the electrolyzed water module is not appropriate, the sterilization effect of the electrolyzed water will be poor, affecting the user experience.

Means for Solving the Problems

[0005] The present invention adopts the following technical means. In one aspect, the method for balancing the polarity inversion of the electrolyzed water module of the present invention is as follows: obtaining the difference between the total positive electrode energization time and the total negative electrode energization time; when the absolute value of the difference is not greater than the set value, controlling to invert the polarity of the electrolyzed water module; when the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, controlling to invert the polarity of the electrolyzed water module, and if not, not inverting the polarity.

[0006] Preferably, before obtaining the difference between the total positive electrode energization time and the total negative electrode energization time, receiving a water outlet command from the user, controlling the electrolyzed water module to conduct electricity to discharge water; receiving a water cut-off command from the user, controlling the electrolyzed water module to cut off the power supply to cut off the water; obtaining the current energization time of the electrolyzed water module, determining the current polarity of the electrolyzed water module, if it is the positive electrode, increasing the total positive electrode energization time by the current energization time, and if it is the negative electrode, increasing the total negative electrode energization time by the current energization time.

[0007] Preferably, the set value is a fixed value or a variable value.

[0008] Preferably, when the set value is a variable value, the acquisition method is as follows: T1=n*(V2-V1) / ((V2 / V1)*2) wherein, T1 is the set value, n is the number of times the electrolyzed water module has already inverted its polarity, V1 is the voltage at the first use of the electrolyzed water module, and V2 is the voltage value of the electrolyzed water module detected in real time.

[0009] Preferably, when the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, it includes the step of controlling to invert the polarity of the electrolyzed water module, and if not, not inverting the polarity. Specifically, When the absolute value of the difference is greater than the set value and the total positive electrode energization time is greater than the total negative electrode energization time, if the current polarity of the electrolyzed water module is the positive electrode, control is performed to reverse the electrolyzed water module to the negative electrode; if the current polarity of the electrolyzed water module is the negative electrode, control is performed so as not to reverse the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total negative electrode energization time is greater than the total positive electrode energization time, if the current polarity of the electrolyzed water module is the negative electrode, control is performed to reverse the electrolyzed water module to the positive electrode; if the current polarity of the electrolyzed water module is the positive electrode, control is performed so as not to reverse the polarity of the electrolyzed water module.

[0010] Preferably, controlling the electrolyzed water module to reverse its polarity includes reversing the polarity after controlling the electrolyzed water module to cut off the water or reversing the polarity before controlling the electrolyzed water module to discharge the water.

[0011] In another aspect, the present invention is a polarity inversion balancing device for an electrolyzed water module, including a energization time difference acquisition module that acquires the difference between the total positive electrode energization time and the total negative electrode energization time, and when the absolute value of the difference is less than or equal to the set value, controlling the electrolyzed water module to reverse its polarity, and when the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, controlling the electrolyzed water module to reverse its polarity, and otherwise, a polarity inversion control module that does not reverse the polarity.

[0012] Preferably, the electrolyzed water module further includes a water discharge control module that receives a water discharge command from a user and controls the electrolyzed water module to conduct electricity to discharge water, a water cut-off control module that receives a water cut-off command from a user and controls the electrolyzed water module to cut off the power supply to cut off the water, and an energization time accumulation module that acquires the current energization time of the electrolyzed water module, determines the current polarity of the electrolyzed water module, and if it is the positive electrode, increases the total positive electrode energization time by the current energization time, and if it is the negative electrode, increases the total negative electrode energization time by the current energization time.

[0013] Preferably, the polarity inversion balancing device of the electrolyzed water module further includes a set value acquisition module for acquiring a fixed set value or a changing set value. When the set value is a variable value, the acquisition method is as follows: T1=n*(V2-V1) / ((V2 / V1)*2) Among them, T1 is the set value, n is the number of times the electrolyzed water module has already undergone polarity inversion, V1 is the voltage at the first use of the electrolyzed water module, and V2 is the voltage value of the electrolyzed water module detected in real time.

[0014] Preferably, the polarity inversion control module specifically: When the absolute value of the difference is not greater than the set value, control is performed to invert the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total positive electrode energization time is greater than the total negative electrode energization time, if the current polarity of the electrolyzed water module is the positive electrode, control is performed to invert the electrolyzed water module to the negative electrode; if the current polarity of the electrolyzed water module is the negative electrode, control is performed not to invert the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total negative electrode energization time is greater than the total positive electrode energization time, if the current polarity of the electrolyzed water module is the negative electrode, control is performed to invert the electrolyzed water module to the positive electrode; if the current polarity of the electrolyzed water module is the positive electrode, control is performed not to invert the polarity of the electrolyzed water module.

[0015] In yet another aspect, the present invention is an electrolyzed water system, including an electrolyzed water module, a polarity inversion circuit, and a control circuit. The electrolyzed water module includes a positive electrode and a negative electrode. The control circuit is connected to the polarity inversion circuit and is used to control the polarity inversion circuit based on the difference between the total positive electrode energization time and the total negative electrode energization time of the electrolyzed water module. The polarity inversion circuit is connected to the electrolyzed water module and is used to control whether the electrolyzed water module performs polarity inversion based on the output command of the control circuit. The control circuit is also connected to the electrolyzed water module and is used to control the water output or water cut-off of the electrolyzed water module based on the user's command.

[0016] Preferably, the polarity inversion circuit is connected to the electrolyzed water module and controls whether the electrolyzed water module undergoes polarity inversion based on the output command of the control circuit. Specifically, the difference between the total positive electrode energization time and the total negative electrode energization time of the electrolyzed water module is obtained. When the absolute value of the difference is not greater than the set value, the polarity inversion circuit is controlled to invert the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, the polarity inversion circuit is controlled to invert the polarity of the electrolyzed water module. Otherwise, the polarity is not inverted.

[0017] Preferably, the polarity inversion circuit has a connected relay and a switch tube. The relay includes two sets of contacts with normally open contacts and normally closed contacts. The control circuit is connected to the switch tube and controls the opening and closing of the switch tube. The switch tube is connected to the coil of the relay. The normally open contact of the first set of contacts of the relay is connected to the normally closed contact of the second set of contacts and is connected to one pole of the electrolyzed water module. The normally closed contact of the second set of contacts of the relay is connected to the normally open contact of the second set of contacts and is connected to the other pole of the electrolyzed water module.

Advantages of the Invention

[0018] The advantageous effects of the present invention compared with the prior art are as follows. (1) By controlling the polarity inversion based on the difference between the total positive electrode energization time and the total negative electrode energization time, the electrolyzed sterilizing water generated by the electrolyzed water module can achieve a balance in acid-base degree, contribute to the improvement of the lifespan of the electrolyzed water module, and achieve a higher sterilization effect. (2) There is a certain upper limit to the number of polarity reversals of the electrolyzed water module. When the number of polarity reversals reaches the upper limit, the acid and alkali ion concentrations inside the electrolyzed water module become unbalanced, resulting in a poor sterilization effect. The present invention sets a set value based on the number of polarity reversals, the initial voltage value, and the real-time voltage value of the electrolyzed water module to control the polarity reversal. Such a polarity reversal method reduces the number of polarity reversals of the electrolyzed water module as the set value changes, which is advantageous for extending the service life of the electrolyzed water module. (3) Performing a polarity reversal during water discharge, that is, switching the polarity of the electrolyzed water module during water discharge, causes an imbalance in the acid and alkali ion concentrations of the generated electrolyzed water. Therefore, the present invention controls not to perform a polarity reversal during water discharge of the electrolyzed water module, and further achieves a balance in the acidity and alkalinity of the electrolyzed sterilized water generated by the electrolyzed water module.

Embodiments for Carrying Out the Invention

[0022] Hereinafter, with reference to the drawings in the embodiments of the present invention, the technical aspects in the embodiments of the present invention will be clearly and completely described. The described embodiments are only some embodiments of the present invention and do not explain all embodiments. It is obvious that all other embodiments that can be implemented by those skilled in the art without creative efforts based on the embodiments of the present invention are included in the protection scope of the present invention.

[0023] In the description of the present invention, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion. Therefore, a process, method, article, or device including a list of elements includes not only those elements but also other elements not explicitly listed, or elements specific to such a process, method, article, or device. It should be understood that an element defined by the expression "comprising one..." does not exclude the presence of additional identical elements in the process, method, article, or device including the said element without further limitation.

[0024] In the description of the present invention, the positions or positional relationships indicated by terms such as "upper", "lower", "inner", "outer", "top / bottom", etc. are based on the positions or positional relationships shown in the drawings, and are merely for facilitating the description of the present invention and simplifying the description, and do not expressly or implicitly imply that the device or element mentioned must have a specific position, be configured and operate at a specific position. Therefore, it should be understood that it should not be construed as a limitation of the present invention. Furthermore, the terms "first", "second", etc. are only for the purpose of description and should not be understood as indicating relative importance expressly or implicitly.

[0025] In the description of the present invention, unless otherwise expressly specified or limited, terms such as "mount", "comprise", "set / connect", "connect", etc. should be understood in a broad sense. For example, "connect" may mean fixedly connected, detachably connected, integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intervening object, or communication inside two elements. A person skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific situation.

[0026] Note that in the description of the present invention, unless otherwise expressly specified and limited, step labels S101, S102, S103, etc. are for convenience and do not indicate the execution order, and the execution order of each can be adjusted.

[0027] <Example 1> As shown in FIG. 1, the method for polar inversion balance of the electrolyzed water module of the present invention includes: S101 of obtaining the difference between the total positive electrode energization time and the total negative electrode energization time; S102 of controlling to invert the polarity of the electrolyzed water module when the absolute value of the difference is not greater than the set value; S103 of controlling to invert the polarity of the electrolyzed water module when the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, and not inverting the polarity otherwise.

[0028] Specifically, the execution entity of the polarity inversion balancing method of the electrolyzed water module in this embodiment may be a control circuit / terminal device including a controller such as an MCU in which a software program for realizing the above method is stored.

[0029] When the electrolyzed water module is used for the first time, the total positive electrode energization time and the total negative electrode energization time are each initialized to 0, and with subsequent use, the total positive electrode energization time and the total negative electrode energization time are respectively integrated according to the energization polarity of the electrolyzed water module. If the polarity is the positive electrode when the water flows out this time, the total positive electrode energization time is increased by the current energization time, and if not, the total negative electrode energization time is increased by the current energization time.

[0030] Specifically, before obtaining the difference between the total positive electrode energization time and the total negative electrode energization time, it is necessary to obtain the total positive electrode energization time and the total negative electrode energization time. Receive the user's water discharge command, control the electrolyzed water module to conduct electricity to discharge water. Receive the user's water cut-off command, control the electrolyzed water module to cut off the power to cut off the water. Obtain the current energization time of the electrolyzed water module, determine the current polarity of the electrolyzed water module. If it is the positive electrode, increase the total positive electrode energization time by the current energization time, and if it is the negative electrode, increase the total negative electrode energization time by the current energization time.

[0031] Note that when the electrolyzed water module is energized to discharge water, the counting of the energization time starts, and when the electrolyzed water module is energized to cut off the water, the counting of the energization time stops, and the time between the two is the current energization time.

[0032] When the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, control the electrolyzed water module to reverse the polarity, and if not, do not reverse the polarity.

[0033] Specifically, when the absolute value of the difference is greater than the set value and the total positive electrode energization time is greater than the total negative electrode energization time, if the current polarity of the electrolyzed water module is the positive electrode, it is controlled to reverse the electrolyzed water module to the negative electrode; if the current polarity of the electrolyzed water module is the negative electrode, it is controlled not to reverse the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total negative electrode energization time is greater than the total positive electrode energization time, if the current polarity of the electrolyzed water module is the negative electrode, it is controlled to reverse the electrolyzed water module to the positive electrode; if the current polarity of the electrolyzed water module is the positive electrode, it is controlled not to reverse the polarity of the electrolyzed water module.

[0034] In this embodiment, the set value is set to a fixed value of, for example, 15 s.

[0035] Specifically, as shown in FIG. 2, when the electrolyzed water module is energized, the energization time and the corresponding polarity of the electrolyzed water module are counted each time, and each time the user turns off the water, the water outlet time each time is recorded. Also, each time the water is turned off, the total positive electrode energization time T2 and the total negative electrode energization time T3 are detected. When it is detected that the difference between the total positive electrode energization time and the total negative electrode energization time exceeds the set value T1 (for example, 15 seconds), polarity time compensation of the electrolyzed water module is performed.

[0036] When it is detected that the difference between the total positive electrode energization time and the total negative electrode energization time exceeds the set value T1, the software first determines the relationship between the total positive electrode energization time and the total negative electrode energization time, that is, (1) T2 > T3, or (2) T2 < T3. In case (1), the electrolyzed water module compensates the total negative electrode energization time, that is, it is energized to the negative electrode at the next water outlet. In case (2), the total positive electrode energization time is compensated, and the electrolyzed water module is energized to the positive electrode at the next water outlet. If the difference between the two does not exceed T1 (15 s), the correction is stopped, and the electrolyzed water module normally reverses its polarity.

[0037] That is, when |T2 - T3| < T1 is satisfied, the polarity is reversed when the water is turned off; when |T2 - T3| > T1 is satisfied, the polarity is not reversed when the water is turned off, and compensation is performed. When |T3 - T2| < T1 is satisfied, the polarity is reversed when the water is turned off. When |T3 - T2| > T1 is satisfied, the polarity is not reversed when the water is turned off, and compensation is performed.

[0038] In addition, after the water is turned off (for example, when receiving a water cut-off command from the user), the electrolyzed water module may be controlled to reverse the polarity, or before the water is discharged (for example, when receiving a water discharge command from the user), the electrolyzed water module may be controlled to reverse the polarity. This embodiment is not particularly limited as long as the polarity is not reversed when the electrolyzed water module discharges water. Reversing the polarity at the time of discharging water, that is, switching the polarity of the electrolyzed water module at the time of discharging water, causes an imbalance in the acid-alkali ion concentration of the generated electrolyzed water. Therefore, the present invention controls so as not to reverse the polarity when the electrolyzed water module discharges water, and further realizes the balance of the acid-alkalinity of the electrolyzed sterilizing water generated by the electrolyzed water module.

[0039] As a conclusion, as shown in FIG. 3, the polarity reversal balancing method of the electrolyzed water module of the present invention specifically includes receiving a water discharge command from the user, controlling the electrolyzed water module to conduct electricity, and discharging water; receiving a water cut-off command from the user, controlling the electrolyzed water module to cut off the power supply, and turning off the water; acquiring the current energization time of the electrolyzed water module, determining the current polarity of the electrolyzed water module, if it is the positive electrode, increasing the total positive electrode energization time by the current energization time, and if it is the negative electrode, increasing the total negative electrode energization time by the current energization time; acquiring the difference between the total positive electrode energization time and the total negative electrode energization time; when the absolute value of the difference does not exceed a fixed set value, controlling the electrolyzed water module to reverse the polarity; when the absolute value of the difference is greater than the fixed set value and the total positive electrode energization time is greater than the total negative electrode energization time, if the current polarity of the electrolyzed water module is the positive electrode, controlling the electrolyzed water module to be reversed to the negative electrode, and if the current polarity of the electrolyzed water module is the negative electrode, controlling the electrolyzed water module not to reverse the polarity; When the absolute value of the difference is greater than a fixed set value and the total negative electrode energization time is greater than the total positive electrode energization time, if the current polarity of the electrolyzed water module is the negative electrode, control is performed to reverse the electrolyzed water module to the positive electrode, and if the current polarity of the electrolyzed water module is the positive electrode, control is performed not to reverse the polarity of the electrolyzed water module.

[0040] Referring to FIG. 4, according to another aspect of the present invention, the present invention further includes an electrolyzed water module polarity inversion balance device corresponding to the above-described electrolyzed water module polarity inversion balance method. Specifically, A energization time difference acquisition module 401 for acquiring the difference between the total positive electrode energization time and the total negative electrode energization time; When the absolute value of the difference is less than or equal to the set value, control is performed to reverse the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, control is performed to reverse the polarity of the electrolyzed water module. Otherwise, a polarity inversion control module 402 that does not perform polarity inversion is included.

[0041] Furthermore, the electrolyzed water module polarity inversion balance device An outwater control module 403 for receiving a user's outwater command and controlling the electrolyzed water module to conduct electricity to discharge water; A water cutoff control module 404 for receiving a user's water cutoff command and controlling the electrolyzed water module to cut off the power to cut off the water; An energization time accumulation module 405 for acquiring the current energization time of the electrolyzed water module, determining the current polarity of the electrolyzed water module, and if it is the positive electrode, increasing the total positive electrode energization time by the current energization time, and if it is the negative electrode, increasing the total negative electrode energization time by the current energization time.

[0042] Specifically, the polarity inversion control module 402 When the absolute value of the difference is not greater than the set value, control is performed to reverse the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total positive electrode energization time is greater than the total negative electrode energization time, if the current polarity of the electrolyzed water module is the positive electrode, control is performed to reverse the electrolyzed water module to the negative electrode, and if the current polarity of the electrolyzed water module is the negative electrode, control is performed not to reverse the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total negative electrode energization time is greater than the total positive electrode energization time, if the current polarity of the electrolyzed water module is the negative electrode, control is performed to reverse the electrolyzed water module to the positive electrode, and if the current polarity of the electrolyzed water module is the positive electrode, control is performed not to reverse the polarity of the electrolyzed water module.

[0043] In this embodiment, the polarity inversion is controlled according to the difference between the total positive electrode energization time and the total negative electrode energization time, so that the electrolyzed sterilized water generated by the electrolyzed water module can obtain a balance of acid and alkalinity, contribute to the improvement of the life of the electrolyzed water module, and achieve a higher sterilization effect.

[0044] <Example 2> In this embodiment, the set value is a variable value. Specifically, the points obtained by calculation based on the number of polarity inversions, the initial voltage value of the electrolyzed water module, and the real-time voltage value are different from those in Embodiment 1.

[0045] Similar to Embodiment 1, as shown in FIG. 1, the polarity inversion balancing method of the electrolyzed water module of the present invention includes: S101 for obtaining the difference between the total positive electrode energization time and the total negative electrode energization time; S102 for controlling to reverse the polarity of the electrolyzed water module when the absolute value of the difference is not greater than the set value; S103 for controlling to reverse the polarity of the electrolyzed water module when the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, and not reversing the polarity otherwise.

[0046] Specifically, the entity that executes the polarity inversion equilibrium method of the electrolyzed water module in this embodiment may be a control circuit / terminal device including a controller such as an MCU in which a software program for realizing the method is stored.

[0047] When the electrolyzed water module is used for the first time, the total positive electrode energization time and the total negative electrode energization time are respectively initialized to 0, and as the use continues, the total positive electrode energization time and the total negative electrode energization time are respectively integrated according to the energization polarity of the electrolyzed water module. If the polarity is the positive electrode when the water flows out this time, the total positive electrode energization time is increased by the current energization time, otherwise, the total negative electrode energization time is increased by the current energization time.

[0048] Specifically, it further includes obtaining the total positive electrode energization time and the total negative electrode energization time before calculating the difference between the total positive electrode energization time and the total negative electrode energization time. Receive the user's water discharge command, control the electrolyzed water module to conduct electricity to discharge water. Receive the user's water cut-off command, control the electrolyzed water module to cut off the power to cut off the water. Obtain the current energization time of the electrolyzed water module, judge the current polarity of the electrolyzed water module. If it is the positive electrode, increase the total positive electrode energization time by the current energization time. If it is the negative electrode, increase the total negative electrode energization time by the current energization time.

[0049] Note that when the electrolyzed water module is energized to discharge water, the counting of the energization time starts, and when the electrolyzed water module is energized to cut off the water, the counting of the energization time stops, and the time between the two is the current energization time.

[0050] When the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, control the electrolyzed water module to invert the polarity. Otherwise, do not invert the polarity. Specifically, When the absolute value of the difference is greater than the set value and the total positive electrode energization time is greater than the total negative electrode energization time, if the current polarity of the electrolyzed water module is the positive electrode, control is performed to reverse the electrolyzed water module to the negative electrode; if the current polarity of the electrolyzed water module is the negative electrode, control is performed not to reverse the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total negative electrode energization time is greater than the total positive electrode energization time, if the current polarity of the electrolyzed water module is the negative electrode, control is performed to reverse the electrolyzed water module to the positive electrode; if the current polarity of the electrolyzed water module is the positive electrode, control is performed not to reverse the polarity of the electrolyzed water module.

[0051] In this embodiment, the set value is a variable value, and the specific calculation method is as follows. T1=n*(V2-V1) / ((V2 / V1)*2) Among them, T1 is the set value, n is the number of times the electrolyzed water module has already been polarity-reversed, V1 is the voltage at the first use of the electrolyzed water module, and V2 is the voltage value of the electrolyzed water module detected in real time.

[0052] As shown in FIGS. 5 and 6, along with the difference in the change amount of the electrolyzed water module voltage value and the increase in the number of polarity reversals, the set value T1 of the difference in the energization correction time between the positive electrode and the negative electrode also changes. The advantage of the dynamic change of T1 is that there is an upper limit to the number of times the electrolyzed water module is polarity-reversed. When the number of polarity reversals reaches the upper limit, the acid and alkali ion concentrations inside the electrolyzed water module become unbalanced, resulting in a poor sterilization effect. The drawback of setting a certain time for polarity reversal is that if the number of polarity reversals is too large, it will affect the sterilization effect and the module life. This polarity reversal method can reduce the number of module polarity reversals associated with the change of T1, which is beneficial for extending the life of the electrolyzed water module.

[0053] Note that after the water is cut off (for example, when receiving the user's water cut-off command), the electrolyzed water module may be controlled to reverse its polarity, or before the water is discharged (for example, when receiving the user's water discharge command), the electrolyzed water module may be controlled to reverse its polarity. The present embodiment is not particularly limited as long as the electrolyzed water module does not reverse its polarity during water discharge. When reversing the polarity during water discharge, that is, when switching the polarity of the electrolyzed water module during water discharge, there is a risk of causing an imbalance in the acid-alkali ion concentration of the electrolyzed water. Therefore, in the present invention, by controlling the electrolyzed water module not to reverse its polarity during water discharge, the balance of the acidity and alkalinity of the electrolyzed sterilized water by the electrolyzed water module can be further achieved.

[0055] Referring to FIG. 8, according to another aspect of the present invention, the present invention further includes a polarity inversion balancing device for an electrolyzed water module corresponding to the polarity inversion balancing method of the electrolyzed water module described above. Specifically, A energization time difference acquisition module 801 for acquiring the difference between the total positive electrode energization time and the total negative electrode energization time; When the absolute value of the difference is not greater than the set value, control is performed to reverse the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the current polarity is the polarity with the longer total energization time, control is performed to reverse the polarity of the electrolyzed water module. Otherwise, a polarity inversion control module 802 that does not reverse the polarity is included.

[0057] The polarity inversion balancing device for the electrolyzed water module further includes a set value acquisition module 806 for acquiring a fixed set value or a changing set value. When the set value is a variable value, the acquisition method is as follows: T1=n*(V2 - V1) / ((V2 / V1)*2) Among them, T1 is a set value, n is the number of times the electrolyzed water module has already undergone polarity inversion, V1 is the voltage at the first use of the electrolyzed water module, and V2 is the voltage value of the electrolyzed water module detected in real time.

[0058] The polarity inversion control module 802 specifically When the absolute value of the difference is not greater than the set value, it controls to invert the polarity of the electrolyzed water module. When the absolute value of the difference is greater than the set value and the total positive electrode energization time is greater than the total negative electrode energization time, if the current polarity of the electrolyzed water module is the positive electrode, it controls to invert the electrolyzed water module to the negative electrode; if the current polarity of the electrolyzed water module is the negative electrode, it controls not to invert the polarity of the electrolyzed water module.

[0059] This embodiment sets a set value based on the number of polarity inversions, the initial voltage value and the real-time voltage value of the electrolyzed water module to control the polarity inversion. Such a polarity inversion method is beneficial to reduce the number of polarity inversions of the electrolyzed water module and extend the service life of the electrolyzed water module as the set value changes.

The polarity inversion circuit 91 is connected to the electrolyzed water module 90 and is for controlling the presence or absence of polarity inversion of the electrolyzed water module 90 based on the output command of the control circuit 92. The control circuit 92 is also connected to the electrolyzed water module 90 and controls the water output or water cut-off of the electrolyzed water module 90 according to the user's command.

[0061] In this embodiment, the control circuit 92 includes an MCU controller for executing the steps of the polarity inversion balance method of the electrolyzed water module 90 described in Embodiment 1 or Embodiment 2.

The control circuit 92 is connected to the switch tube Q2 to control the on / off of the switch tube Q2. The switch tube Q2 is connected to the coil of the relay K1. The normally open contact of the first set of contacts of the relay K1 and the normally closed contact of the second set of contacts are connected and connected to one pole of the electrolyzed water module 90. The normally closed contact of the second set of contacts of the relay K1 is connected to the normally open contact of the second set of contacts and connected to the other pole of the electrolyzed water module 90.

[0063] Specifically, the switch tube Q2 is an NPN transistor. The base of the transistor is connected to the control circuit 92. The emitter of the transistor is grounded. The collector of the transistor is connected to the relay K1.

[0064] When the control circuit 92 outputs a high level to the ON_3 signal pin, a set of contacts of the relay K1 switches to 2 and 7, a positive voltage is applied to the electrolyzed water module 90, and positive ion electrolyzed water is output. When the control circuit 92 outputs a low level to the ON_3 signal pin, the other set of contacts of the relay K1 switches to 4 and 5, a negative voltage is applied to the electrolyzed water module 90, and negative ion electrolyzed water is output. In daily use, by controlling the high level and low level of the ON_3 signal pin, the concentrations of positive and negative ion electrolyzed water generated by the electrolyzed water module 90 are balanced.
