DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following describes a control method and device for drinking water equipment, a storage medium, and drinking water equipment according to an embodiment of the present invention with reference to the accompanying drawings.

[0034] In order to better describe the control method of the drinking water device in the present invention, the operation of the drinking water device is briefly described below. Figure 1 As shown, the drinking water equipment includes an electrolysis module 10, a water inlet device 15, a first three-way valve 11, a second three-way valve 12 and a water outlet 13, the electrolysis module 10 includes a water inlet and two water outlets, wherein the water inlet 100 is used to connect with the water inlet device 15, and the two water outlets are respectively a first water outlet 101 and a second water outlet 102; the first three-way valve 11 and the second three-way valve 12 also include a water inlet and two water outlets, which are respectively an input end 110, a first output end 111 and a second output end 112 of the first three-way valve, and an input end 120, a first output end 121 and a second output end 122 of the second three-way valve.

[0035] Specifically, the electrolysis module 10 is connected to the input end 110 of the first three-way valve through the first water outlet 101, and the electrolysis module 10 is connected to the input end 120 of the second three-way valve through the second water outlet 102. The first output end 111 of the first three-way valve and the first output end 121 of the second three-way valve are respectively connected to the water inlet 100, and the second output end 112 of the first three-way valve and the second output end 122 of the second three-way valve are respectively connected to the water outlet 13.

[0036] First, the water inlet device 15 controls the tap water / purified water to enter the electrolysis module 10 through the water inlet 100, and the electrolysis module 10 electrolyzes and separates the tap water / drinking water to obtain alkaline water and acidic water. Figure 1 The upper end of the electrolysis module 10 is the anode side and the lower end is the cathode side for example, wherein acidic water is generated at the upper end and flows to the first three-way valve 11 through the first water outlet 101, while alkaline water is generated at the lower end and flows to the second three-way valve 12 through the second water outlet 102. The first three-way valve 11 and the second three-way valve 12 each include two output ends, one of which is connected to the water inlet 100, and the other is connected to the water outlet 13. In this example, when the user needs to use acidic water, the input end 110 of the first three-way valve 11 can be controlled to be connected to the second output end 112, while the first output end 111 is closed, and the input end 120 of the second three-way valve 12 can be controlled to be connected to the first output end 121, while the second output end 122 is closed, that is, the acidic water generated at the upper end of the electrolysis module 10 can be led out from the water outlet 13, and the alkaline water generated at the lower end of the electrolysis module 10 can flow back into the electrolysis module 10. It should be noted that if the user needs to use alkaline water, the control modes of the first three-way valve 11 and the second three-way valve 12 are interchanged, so that the alkaline water produced at the lower end of the electrolysis module 10 is discharged from the water outlet 13, while the acidic water produced at the upper end of the electrolysis module 10 flows back into the electrolysis module 10.

[0037] like Figure 1As shown, the drinking water device in this embodiment also includes a pH sensor 14, and the tap water / purified water enters the electrolysis module 10 through the water inlet 100 through the water inlet device 15; after the tap water / purified water enters the electrolysis module 10, the control program starts the electrolysis module 10 to electrolyze water, and outputs acidic water to the first three-way valve 11 through the first water outlet 101, and outputs alkaline water to the second three-way valve 12 through the second water outlet 102. At the same time, the pH sensor 14 is installed between the second water outlet 101 and the second three-way valve 12 to detect the pH of the alkaline water channel. Since the pH of the acidic water channel water is correlated with the alkaline water channel water, the specific correlation formula can be calibrated and fitted through experimental data or historical data. Therefore, after the pH of the alkaline water channel water is detected, the pH of the acidic water channel water can be determined according to the pH of the alkaline water channel water. The acidic water generated by the electrolysis module 10 can flow to the first three-way valve 11, and the alkaline water can flow to the second three-way valve 12. After obtaining the user's target pH, the control program controls the conduction direction of the first three-way valve 11 and the second three-way valve to output water corresponding to the target pH to the water outlet 15.

[0038] like Figure 2 As shown, in some embodiments of the present invention, the control method of the drinking water equipment includes the following steps:

[0039] S201, obtaining the target pH value and actual pH value of the outlet water of the drinking water device.

[0040] Specifically, taking the example that the first water outlet of the electrolysis module is on the anode side and the second water outlet is on the cathode side, after the tap water / purified water is electrolyzed by the electrolysis module, acidic water is output to the first three-way valve through the first water outlet, and alkaline water is output to the second three-way valve through the second water outlet. When the electrolysis module starts working according to the target water outlet pH of the drinking water device, due to the operation time, control error and other reasons, the actual water outlet pH of the drinking water device will not be the same as the target water outlet pH in a short time, so it needs to be further adjusted according to the actual water outlet pH and the target water outlet pH.

[0041] In this embodiment, a pH sensor can be set in the waterway where alkaline water passes and / or the waterway where acidic water passes, and the actual pH of the outlet water can be obtained through the pH sensor. Since acidic water and alkaline water are obtained by electrolysis through the same electrolysis module, there is a certain correlation between the two. In this embodiment, after fitting through experimental data or historical data, the relationship equation between acidic water and alkaline water can be determined as follows: pH 碱性 =-1.0408pH 酸性 +14.642, where pH 碱性 Indicates the acidity or alkalinity of alkaline water, pH 酸性It should be noted that the specific values ​​of -1.0408 and 14.642 in the relationship equation are related to the application environment of the electrolysis module, the model of the electrolysis module, etc., and are calibrated according to actual conditions. No specific limitation is made here. This embodiment is fitted through the following table.

[0042] <![CDATA[pH 碱性 ]]> <![CDATA[pH 酸性 ]]> 12 2.2 10 4.1 7 7.4 5 9.5 3 11.6 1 13.5

[0043] Specifically, in order to accurately obtain the pH of water in the acidic water channel and the alkaline water channel, the pH sensor can be arranged between the first water outlet and the input end of the first three-way valve, and / or between the second water outlet and the input end of the second three-way valve.

[0044] In addition, the target outlet water pH in this embodiment can be obtained through a display control panel of the drinking water device, a mobile phone application, or the cloud, etc., and is not specifically limited here.

[0045] S202, performing closed-loop control on the driving voltage of the electrolysis module according to the actual outlet water pH and the target outlet water pH.

[0046] Specifically, after the actual pH value of the outlet water and the target pH value of the outlet water are detected, in order to ensure that the pH value of the outlet water provided by the water outlet can be the same as the target pH value of the outlet water, the present embodiment can first control the first three-way valve and the second three-way valve not to supply water to the water outlet, but adjust the operating parameters of the electrolysis module in real time according to the difference between the actual pH value of the outlet water and the target pH value of the outlet water. Specifically, the power supply voltage or output voltage PWM (Pulse width modulation) of the electrolysis module can be adjusted to adjust the actual pH value of the outlet water at the first water outlet and the second water outlet of the electrolysis module, so that the difference between the actual pH value of the outlet water and the target pH value of the outlet water gradually decreases until they are the same, and then output water with the target pH value of the outlet water to the water outlet.

[0047] In some specific embodiments of the present invention, Figure 3 As shown, the control method of the drinking water equipment also includes:

[0048] S301, when the target outlet water pH is greater than the preset pH, the first output end of the first three-way valve and the second output end of the second three-way valve are controlled to be in an open state, and the second output end of the first three-way valve and the first output end of the second three-way valve are controlled to be in a closed state.

[0049] S302, when the target outlet water pH is less than the preset pH, the second output end of the first three-way valve and the first output end of the second three-way valve are controlled to be in an open state, and the first output end of the first three-way valve and the second output end of the second three-way valve are controlled to be in a closed state.

[0050] S303, when the target outlet water pH is equal to the preset pH, the electrolysis module is controlled to stop running, and the second output end of the first three-way valve and / or the second output end of the second three-way valve are in an open state.

[0051] Specifically, since tap water or purified water is not neutral water but weakly alkaline or weakly acidic, the preset pH in this embodiment cannot be set to a neutral value of 7. More specifically, the preset pH in this embodiment can be set to the pH of tap water / purified water, that is, the pH of the water source provided to the drinking water device, and then the first three-way valve and the second three-way valve in the drinking water device are adjusted according to the difference between the preset pH and the target pH of the outlet water, so that the actual pH of the outlet water of the drinking water device is the same as the target pH of the outlet water.

[0052] Taking the example that the first water outlet of the electrolysis module is at the anode side and the second water outlet is at the cathode side, when the electrolysis module is working, the pH of the water outlet of the first water outlet is less than the preset pH, and the pH of the water outlet of the second water outlet is greater than the preset pH. When the target pH of the water outlet is greater than the preset pH, the first output end of the first three-way valve and the second output end of the second three-way valve are controlled to be in an open state, while the second output end of the first three-way valve and the first output end of the second three-way valve are in a closed state. At this time, after the water in the first three-way valve flows in from the input end, it flows back to the water inlet from the first output end, and the electrolysis is circulated. After the water in the second three-way valve flows in from the input end, it is output to the water outlet through the second output end. When the target outlet water pH is less than the preset pH, the second output end of the first three-way valve and the first output end of the second three-way valve are controlled to be in an open state, while the first output end of the first three-way valve and the second output end of the second three-way valve are in a closed state. At this time, after the water in the first three-way valve flows in from the input end, it is output to the water outlet through the second output end. After the water in the second three-way valve flows in from the input end, it flows back to the water inlet through the first output end, and the electrolysis is circulated. When the target outlet water pH is equal to the preset pH, it means that the pH of the tap water / purified water is equal to the target outlet water pH of the drinking water equipment. At this time, in order to reduce energy consumption, the electrolysis module can be controlled to stop running, and the second output end of the first three-way valve and / or the second output end of the second three-way valve can be controlled to be in an open state, that is, the tap water / purified water can be discharged through the first three-way valve and the second three-way valve without backflow. Controlling the two three-way valves to supply water at the same time can improve the water supply efficiency. Of course, if the water pressure of the water supplied at the same time is too high, in order to avoid splashing during the water supply process, one three-way valve can be controlled to supply water and the other three-way valve can be controlled to backflow.

[0053] In some specific embodiments of the present invention, the drinking water equipment further comprises a water inlet device, which is disposed between the water inlet and the water inlet of the electrolysis module and is used to adjust the water inlet flow rate of the electrolysis module.

[0054] Specifically, the water inlet device in this embodiment can be a water pump, the water inlet of the water pump can be connected to the water supply port, the water supply port can be a tap of tap water or the water outlet of a clean water tank, and the water outlet of the water pump is connected to the water inlet of the electrolysis module of the drinking water equipment in the present invention, and the water pump can adjust the water inlet flow rate of the electrolysis module. It should be noted that due to the different electrolysis capacities of different electrolysis modules, the water inlet flow rate also needs to be controlled. If the water inlet flow rate is too fast and the electrolysis speed of the electrolysis module is too slow, it will also affect the actual water outlet pH. In some examples, the water outlet pH can also be controlled by controlling the water inlet flow rate of the water inlet device, or by controlling the water inlet flow rate of the water inlet device and the driving voltage of the electrolysis module to adjust the water outlet pH.

[0055] In some specific embodiments of the present invention, Figure 4 As shown, the control method of the drinking water equipment also includes:

[0056] S401, obtaining temperature information of the environment in which the drinking water equipment is located.

[0057] Specifically, the drinking water device is also provided with a temperature sensor for obtaining the ambient temperature. In other embodiments, the drinking water device may also be designed to have positioning and networking functions, and obtain the temperature information of the environment in which the drinking water device is located by obtaining the meteorological information released by the Meteorological Bureau. Of course, the ambient temperature may also be obtained by other means, such as direct input by the user, etc., and the method for obtaining the temperature information of the environment in which the drinking water device is located is not specifically limited here.

[0058] S402, determining the target pH value of the outlet water of the drinking water device according to the temperature information.

[0059] Specifically, people may have different demands for the pH value of domestic water in different seasons, so the target water pH value can also be automatically obtained according to the climate temperature. For example, in summer, due to the high temperature, people tend to sweat easily, so they may prefer to use acidic water for bathing and washing their faces. Weak acidic water can help clean the skin and relieve fatigue. In winter, due to the dry climate, people may prefer to use alkaline water. Weak alkaline water can help keep the skin moisturized and reduce problems such as dry skin and itching.

[0060] The following two relationship models between ambient temperature and target outlet water pH are proposed:

[0061] The first type: pH 目标 =aT 3 +bT 2+cT+d, where T is the ambient temperature, and a, b, c, and d are constants. These constants can be fitted based on experimental data or a large amount of user usage data. The design principle of this function is that within the preset range, as the temperature drops, the target pH value increases.

[0062] Second type:

[0063] <![CDATA[pH 目标 ]]> T 6.6 T≥25℃ 7 18℃≤T＜25℃ 7.3 T＜18℃

[0064] Specifically, as shown in the table above, this embodiment divides the ambient temperature T into three ranges. When the ambient temperature T is greater than or equal to 25 degrees Celsius, the target outlet water pH is determined to be 6.6; when the ambient temperature is greater than or equal to 18 degrees Celsius and less than 25 degrees Celsius, the target outlet water pH is determined to be 7; when the ambient temperature is less than 18 degrees Celsius, the target outlet water pH is determined to be 7.3. It should be noted that the specific value of the target outlet water pH and the range of the ambient temperature in this embodiment can be determined according to actual applications and are not specifically limited here.

[0065] In some specific embodiments of the present invention, Figure 5 As shown, the driving voltage of the electrolysis module is closed-loop controlled according to the actual outlet water pH and the target outlet water pH, including:

[0066] S501, calculating the difference between the actual outlet water pH and the target outlet water pH.

[0067] Specifically, the moment when water begins to flow out is defined as time 0, according to the formula: E = pH 实际 -pH 目标 The difference between the actual pH value of the effluent water and the target pH value of the effluent water is calculated, and then the difference between the actual pH value of the effluent water and the target pH value of the effluent water can be determined, so that correction can be made subsequently for the difference value.

[0068] S502, controlling the driving voltage of the electrolysis module using the PI control principle according to the difference.

[0069] Specifically, this embodiment adopts the PI control principle to perform closed-loop control on the drive motor of the motor module, and the formula is: Wherein, u is the driving voltage, E is the difference between the actual outlet water pH at the current moment and the target outlet water pH; each certain time interval is a moment, in this embodiment, 100ms is a moment, and the water outlet moment is defined as moment 0, The difference E is summed in the time dimension. For example, if n is 5, then It represents the sum of the differences between the actual outlet water pH and the target outlet water pH at each of the first five moments; K p is the proportionality coefficient, K iis the integral coefficient, which is obtained by laboratory debugging. In this embodiment, the proportional coefficient can be 17, 18, 19, 20, etc., and the integral coefficient can be 0.01, 0.015, 0.02, 0.025, etc.

[0070] In this embodiment, u is a driving value, which is applied to the voltage output of the electrolysis module (or the PWM output of the output voltage). The larger u is, the larger the output voltage value (or the PWM output voltage), that is, the greater the driving power is; the smaller u is, the smaller the driving power is. When the driving power is larger, the electrolysis capacity is stronger.

[0071] During the water outlet operation, the control program calculates the real-time driving value according to the above formula, that is, the driving voltage of the electrolysis module is continuously adjusted according to the calculation results, so that the pH value of the outlet water continuously approaches and remains at the target pH value, thereby achieving the purpose of precise pH control.

[0072] In some embodiments of the present invention, the driving voltage of the electrolysis module can also be controlled by using the PID control principle according to the difference. Specifically, the formula of the PID control principle is:

[0073]

[0074] In this control formula, E′ is the difference between the actual outlet water pH at the last fixed moment and the target outlet water pH, K d is the differential coefficient. In this embodiment, the differential coefficient can be 0.1, 0.15, 0.2, 0.25, etc. The meanings of other parameters in this control formula can refer to the relevant description of the above PI control principle formula. In order to avoid redundancy, they will not be repeated here. In addition, for the 0 moment of the water outlet, E' can be set to the difference between the preset pH value and the target pH value of the water outlet.

[0075] Summary, see Figure 6 First, the water inlet device inputs tap water / purified water into the electrolysis module through the water inlet, and at the same time obtains the target outlet water pH through the ambient temperature, and / or, the drinking water equipment display control panel / mobile phone application, etc. If the target outlet water pH is acidic, substitute the acidic target pH into the preset formula to obtain the alkaline target pH, and then use the PI or PID control principle to dynamically adjust the power supply voltage or output voltage PWM of the electrolysis module to achieve the purpose of adjusting the actual outlet water pH, and finally output water with the target outlet water pH. If the target outlet water pH is alkaline water, directly use the PI or PID control principle to dynamically adjust the power supply voltage or output voltage PWM of the electrolysis module to achieve the purpose of adjusting the actual outlet water pH, and finally output water with the target outlet water pH.

[0076] In summary, the control method of the drinking water device in the embodiment of the present invention can accurately and intelligently obtain the target water outlet pH and the actual water outlet pH of the drinking water device, and then perform closed-loop control on the driving voltage of the electrolysis module according to the actual water outlet pH and the target water outlet pH, thereby accurately adjusting the water outlet pH of the drinking water device and improving the user's water use experience.

[0077] Furthermore, the present invention proposes a computer-readable storage medium on which a control program of a drinking water device is stored. When the control program is executed by a processor, the control method of the drinking water device in the above embodiment is implemented.

[0078] The computer-readable storage medium of the embodiment of the present invention can accurately adjust the pH value of the water output from the drinking water device and improve the user's water use experience by executing the control program stored thereon through the processor.
