[0002] With the development of industrial level, people's demand for quality of life is getting higher and higher. In terms of daily water use, water purifiers are designed to purify tap water to remove pollutants in tap water. Among them, the purifier can remove impurities in tap water by filtering or adsorption to obtain pure water.

[0003] In traditional technology, a filter element is usually installed in the purifier to filter tap water and absorb impurities. However, as the filter element is used for a longer time, its ability to absorb impurities in tap water will gradually decrease, resulting in a decrease in the water purification capacity of the water purifier. If the water purification capacity of the water purifier is maintained by the user's independent replacement of the filter element, it will bring inconvenience to the user. Therefore, the current water purifier has the problem of insufficient convenience. Summary of the invention

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0074] The water purification device control method provided in the embodiment of the present application can be applied to the water purification device as shown in Figure 1. For example, in one embodiment, the water purification device is shown in Figure 1, including a hot water pipeline 102, a normal temperature water pipeline 104, a filter element 106, a water outlet pipeline 108, a waste water pipeline 110 and a controller (not shown in the figure), the hot water pipeline 102 and the normal temperature water pipeline 104 are both connected to the filter element 106, and the filter element 106 is connected to the waste water pipeline 110 and the water outlet pipeline 108.

[0075] Among them, the hot water pipeline 102 can input hot water to the filter element 106, and the normal temperature water pipeline 104 can input normal temperature water to the filter element 106. The above hot water and normal temperature water are both unfiltered raw water. After input into the filter element 106, the filter element 106 filters the hot water or normal temperature water, and the filtered pure water can be output through the water outlet pipeline 108 for users to take; when the water purification equipment cleans the filter element 106, the waste water flowing through the filter element 106 can be discharged through the waste water pipeline 110. The filter element 106 can be a core body obtained by arranging and combining ultrafiltration membrane, PP cotton and activated carbon / carbon rod, which is used to filter raw water.

[0076] The controller is connected to the hot water pipeline 102, the normal temperature water pipeline 104, the water outlet pipeline 108 and the waste water pipeline 110. Specifically, solenoid valves are provided on the hot water pipeline 102, the normal temperature water pipeline 104, the water outlet pipeline 108 and the waste water pipeline 110. Each solenoid valve is connected to the controller. The controller controls the opening and closing of the pipeline where each solenoid valve is located by controlling the switch of each solenoid valve, thereby realizing the water purification equipment control method recorded in each embodiment of the present application.

[0077] Furthermore, the water outlet pipe 108 is connected to the waste water pipe 110. On the basis that both the normal temperature water pipe 104 and the hot water pipe 102 include solenoid valves, the water outlet pipe 108 and the waste water pipe 110 may be provided with a solenoid valve only on the waste water pipe 110. Since the side of the water outlet pipe 108 away from the filter element 106 is connected to a faucet, the user can realize the output and cut-off of the water outlet pipe 108 by opening and closing the faucet.

[0078] In an exemplary embodiment, the water purification equipment may also include a flow meter arranged in the water outlet pipe 108, the flow meter is connected to the controller, and can detect the amount of clean water output by the water purification equipment, that is, the water flow rate actually purified by the water purification equipment, corresponding to the water flow rate filtered by the filter element 106, which can be used to estimate the service life of the filter element 106, so that the controller can control the water purification equipment based on the clean water volume.

[0079] In an exemplary embodiment, as shown in FIG2 , a water purification equipment control method is provided, and the method is applied to a controller of a water purification equipment as an example for description, and includes the following steps 202 to 206. Among them:

[0080] Step 202, obtaining the amount of purified water from the water purification equipment.

[0081] Among them, the water purification equipment is provided with a device such as a flow meter that can record the pipeline flow, which is connected to the controller and can transmit the recorded pipeline flow to the controller. For example, a flow meter is provided on the outlet pipeline of the water purification equipment, which can record the water flow of the outlet pipeline and transmit it to the controller, so that the controller can obtain the purified water volume of the water purification equipment.

[0082] Optionally, the pipeline flow recorded by the device may be the amount of clean water, and after being uploaded to the controller, the controller can directly obtain the amount of clean water of the water purification device. The pipeline flow recorded by the device may also be the flow of multiple pipelines including the amount of clean water, for example, the flow of both the water outlet pipeline and the wastewater pipeline. The controller can then analyze the obtained pipeline flow and filter out the flow belonging to the water outlet pipeline as the amount of clean water obtained. In another case, the controller may control the device to start when the water outlet pipeline outputs pure water, and shut down when the water outlet pipeline does not output pure water.

[0083] Step 204, when the purified water volume reaches a preset water overflow threshold, control the water of the first temperature to flush the filter element of the water purification device for a preset flushing time, and soak the filter element for a preset soaking time.

[0084] Among them, the controller stores preset water overflow thresholds, preset flushing times, and preset soaking times. These preset values ​​can be set manually, or determined by the controller based on historical data analysis, or obtained based on big data analysis of other water purification equipment when interacting with the cloud or other terminals.

[0085] Specifically, after obtaining the clean water volume, the controller compares the clean water volume with a preset water overflow threshold value. The preset water overflow threshold value can represent the service life node of the filter element of the water purification device. When the clean water volume reaches the preset water overflow threshold value, it represents that the service life of the filter element has reached this node, which means that the filter element needs to be replaced or cleaned. The controller can control the water of the first temperature to flush and soak the filter element of the water purification device, and the flushing time is the preset flushing time, and the soaking time is the preset soaking time.

[0086] Optionally, the first temperature can be a higher temperature, so that the activated carbon of the filter element can be regenerated while the filter element is soaked. The filter element usually has a carbon rod, which can adsorb organic matter and residual chlorine in the water. However, the activated carbon of the carbon rod will gradually lose its adsorption capacity as its service life is consumed, resulting in poor filtering effect. For this reason, regeneration methods such as thermal regeneration, microwave regeneration, ultrasonic regeneration, biological regeneration, and electrochemical regeneration can be used to restore the vitality of the activated carbon. In this embodiment, by soaking the filter element in water at the first temperature and soaking it for a preset soaking time, the activated carbon can be fully heated, breaking the adsorption equilibrium between the activated carbon and the adsorbate, so that the adsorbate is analyzed and desorbed, thereby achieving the regeneration of the activated carbon.

[0087] When the purified water volume does not reach the preset water overflow threshold, it indicates that the filter element of the water purification equipment has not reached the set service life node, that is, the filter element of the water purification equipment still has a long service life, and there is no need to regenerate the filter element, and there is no need to execute step 204.

[0088] Step 206, based on the clean water volume, the water at the second temperature is controlled to flush the filter element for a preset cleaning time.

[0089] The first temperature is greater than the second temperature, that is, the filter element is first flushed and soaked with water at a higher temperature, and then the filter element is cleaned with water at a lower temperature. Optionally, the water at the first temperature may be water in a hot water pipeline, which is higher than room temperature; the water at the second temperature may be water in a normal temperature water pipeline, which is the temperature of the environment in which the water purification device is located, that is, room temperature.

[0090] Specifically, after the controller completes the soaking of the filter element, it is equivalent to analyzing the substances adsorbed on the filter element. At this time, the filter element needs to be cleaned, that is, the water at the second temperature is controlled to flush the filter element, and the flushing time is the preset cleaning time. Furthermore, the preset cleaning time corresponds to the amount of clean water obtained by the controller, and different amounts of clean water may correspond to different preset cleaning times. It should be noted that whether the filter element is flushed with water at the first temperature or cleaned with water at the second temperature, the water purification equipment at the corresponding moment can open the wastewater pipeline to discharge the flushing and cleaning water from the wastewater pipeline.

[0091] The above-mentioned water purification equipment control method includes obtaining the amount of clean water of the water purification equipment, and when the amount of clean water reaches a preset water overflow threshold, controlling the water of a first temperature to flush the filter element of the water purification equipment for a preset flushing time, and soaking the filter element for a preset soaking time, and based on the amount of clean water, controlling the water of a second temperature to flush the filter element for a preset cleaning time. The first temperature is greater than the second temperature. By using water at a higher temperature to flush, soak and clean the filter element, the filter element can restore its activity through thermal regeneration, thereby extending the service life of the filter element, reducing the frequency of filter element replacement by users, and improving the convenience of the water purification equipment.

[0092] In an exemplary embodiment, as shown in FIG. 3 , after step 202 , the water purification equipment control method further includes steps 302 to 304 .

[0093] Step 302, obtaining historical water usage parameters of the water purification equipment.

[0094] Specifically, the controller is connected to each pipeline and can obtain the data of the flow meter, and can obtain the relevant historical water use parameters such as the previous water consumption, water use time period and water use frequency of the water purification equipment. Furthermore, the controller can sort out the historical water use parameters according to the data of the flow meter or the switch status of each pipeline, so as to facilitate the subsequent analysis based on the historical water use parameters. Exemplarily, the acquired data can be divided according to the size of water consumption, or according to the water use time period at each moment in the 24 hours of each day, or according to the number of water use to divide the water use into early water use or late water use.

[0095] Step 304, determining a low-frequency water usage period based on historical water usage parameters.

[0096] Specifically, the controller divides the historical water use parameters for different time periods according to the water use time periods based on the historical water use parameters, and analyzes the water use records of different time periods in the historical water use parameters based on 24 hours in a day or every 8 hours in a day. It can be obtained how many times water use corresponds to each time interval.

[0097] The controller marks the water use frequency for each time interval based on the number of times water is used in each time interval. Time intervals with less water use, that is, with lower water use frequency, are marked as low-frequency water use periods; time intervals with more water use, that is, with higher water use frequency, are marked as high-frequency water use periods. Similarly, the controller arranges each time interval from low to high according to the number of times water is used and marks the serial numbers based on the set time intervals, and determines the time interval with serial number 1, i.e. the first one, as a low-frequency water use period. Optionally, all time intervals arranged in the first third of the serial numbers can be determined as low-frequency water use periods. The specific number of time intervals marked as low-frequency water use periods can be determined based on actual setting requirements and is not limited here.

[0098] After executing step 304, the controller analyzes the current moment with the low-frequency water use period, that is, analyzes whether the current moment is in the time interval of the low-frequency water use period. If the current moment matches the low-frequency water use period, it indicates that the probability that the user needs to use the water purification device at this time is small, and step 204 can be executed to regenerate the filter element. Regenerating the filter element of the water purification device at this time can reduce the impact on the user's water use.

[0099] In this embodiment, the low-frequency water use period is determined based on the historical water use parameters of the water purification device, and the purified water volume is compared with the preset water overflow threshold only when the current time matches the low-frequency water use period. By analyzing the user's water use habits based on the historical water use parameters, the filter element is cleaned as far away as possible from the time when the user uses water, which is conducive to improving the applicability of the water purification device and ensuring the convenience of users.

[0100] In an exemplary embodiment, the preset water-through threshold includes a first water-through threshold, a second water-through threshold, and a third water-through threshold, the first water-through threshold is less than the second water-through threshold, and the second water-through threshold is less than the third water-through threshold. The first water-through threshold, the second water-through threshold, and the third water-through threshold can all be set manually, and can be selected as any numerical value, as long as the size restrictions between the three are met, and they are not limited in the embodiments of the present application. In the subsequent embodiments, if there is no special explanation, it is assumed that the first water-through threshold, the second water-through threshold, and the third water-through threshold satisfy the above-mentioned size relationship. As shown in Figure 4, step 204 includes steps 402 to 406.

[0101] Step 402, when the purified water volume is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, control the filter element of the water purification device to be flushed with water of a first temperature for a first flushing time and soaked for a first soaking time.

[0102] Step 404, when the purified water volume is greater than the second water overflow threshold and less than or equal to the third water overflow threshold, control the filter element of the water purification device to be flushed with water of the first temperature for a second flushing time and soaked for a second soaking time.

[0103] Step 406, when the purified water volume is greater than the third water flow threshold, control the filter element of the water purification device to be flushed with water of the first temperature for a third flushing time, and soaked for a third soaking time.

[0104] Among them, the first flushing time is less than the second flushing time, and the second flushing time is less than the third flushing time; the first soaking time is less than the second soaking time, and the second soaking time is less than the third soaking time. It should be noted that the first flushing time, the second flushing time, the third flushing time, the first soaking time, the second soaking time and the third soaking time can all be set manually and can be selected as any value. As long as the above size restrictions are met, they are not limited in the embodiments of the present application.

[0105] Specifically, in the first case, the controller compares the water purifier with the preset water overflow threshold. When the purified water volume is less than or equal to the first water overflow threshold, it indicates that the filter element of the current water purification device has been used for a short time, and the impurities adsorbed on the filter element are still small, which does not affect the filtering effect of the filter element. At this time, it is not necessary to perform regeneration steps such as flushing and soaking the filter element. The controller can control the water purification device to work normally to meet the user's water demand. It is not necessary to execute step 204, and it can return to continuous monitoring to obtain the purified water volume of the water purification device.

[0106] In the second case, the controller compares the clean water volume with the preset water overflow threshold. When the clean water volume is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, it indicates that the filter element of the current water purification equipment has been used for a certain period of time, but the loss of service life is not serious, and the filtering effect of the filter element is not greatly damaged. At this time, the controller can control the water of the first temperature to flush and soak the filter element, specifically flushing it with the first flushing time, and soaking it for the first soaking time after flushing. The first flushing time and the first soaking time are both short, which can reduce resource loss on the basis of regenerating the filter element, accurately realize water purification equipment control, and improve the use efficiency of water purification equipment.

[0107] In the third case, the controller compares the clean water volume with the preset water overflow threshold. When the clean water volume is greater than the second water overflow threshold and less than or equal to the third water overflow threshold, it indicates that the use of the filter element of the current water purification equipment has reached a certain extent, the loss of service life is becoming more and more serious, and the filtering effect of the filter element is affected. At this time, the controller can control the water of the first temperature to flush and soak the filter element, specifically flushing it with the second flushing time, and soaking it for the second soaking time after flushing. Both the second flushing time and the second soaking time have a certain duration, which can accurately clean and regenerate the filter element on the basis of reducing resource waste, thereby ensuring the practicality and reliability of the water purification equipment.

[0108] In the fourth case, the controller compares the clean water volume with the preset water overflow threshold. When the clean water volume is greater than the third water overflow threshold, it indicates that the filter element of the current water purification equipment is overused, and the loss of its service life is relatively serious, and the filtering effect of the filter element is seriously damaged. At this time, the filter element needs to be flushed and soaked for a long time for regeneration. At this time, the controller can control the water of the first temperature to flush for a third flushing time, and soak for a third soaking time after flushing. The third flushing time and the third soaking time are both long, which can fully regenerate the filter element, avoid the filter element affecting the water purification effect of the water purification equipment due to limited service life, and reduce the frequency of manual replacement by users, which is conducive to improving the applicability of the water purification equipment.

[0109] Exemplarily, when the amount of clean water is greater than the first water threshold and less than or equal to the second water threshold, the controller can control the hot water pipeline and the waste water pipeline to open, use hot water to flush the filter element for 30 seconds, and close the waste water pipeline after flushing, and use hot water to soak the filter element for 15 minutes. When the amount of clean water is greater than the second water threshold and less than or equal to the third water threshold, the controller can control the hot water pipeline and the waste water pipeline to open, use hot water to flush the filter element for 75 seconds, and close the waste water pipeline after flushing, and use hot water to soak the filter element for 45 minutes. When the amount of clean water is greater than the third water threshold, the controller can control the hot water pipeline and the waste water pipeline to open, use hot water to flush the filter element for 105s, and close the waste water pipeline after flushing, and use hot water to soak the filter element for 90 minutes.

[0110] Optionally, the first flushing time can be set between 10 seconds and 60 seconds; the second flushing time can be set between 60 seconds and 90 seconds; and the third flushing time can be set between 90 seconds and 120 seconds. The first soaking time can be set between 1 minute and 30 minutes; the second soaking time can be set between 30 minutes and 60 minutes; and the third soaking time can be set between 60 minutes and 120 minutes.

[0111] In this embodiment, the filter element is regenerated by comparing the amount of purified water with different preset water overflow thresholds and controlling the flushing and soaking of the filter element for different lengths according to different comparison results, thereby ensuring the activity of the activated carbon in the filter element and further ensuring the water purification efficiency of the water purification equipment.

[0112] In an exemplary embodiment, based on FIG. 4 , step 206 may be as shown in FIG. 5 , where step 206 includes steps 502 to 506 .

[0113] Step 502: When the amount of clean water is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, control the water at the second temperature to flush the filter element for a first cleaning time.

[0114] Step 504: When the amount of clean water is greater than the second water overflow threshold and less than or equal to the third water overflow threshold, the filter element is flushed with water at a second temperature for a second cleaning time.

[0115] Step 506: When the amount of clean water is greater than the third water threshold, the filter element is flushed with water at the second temperature for a third cleaning time.

[0116] The first cleaning time is shorter than the second cleaning time, and the second cleaning time is shorter than the third cleaning time. The first cleaning time, the second cleaning time, and the third cleaning time are all manually set and can be selected as any value as long as the size limit between the three is met, and there is no need to limit the specific value.

[0117] Specifically, in the first case, the controller compares the water purifier with the preset water overflow threshold. When the purified water volume is less than or equal to the first water overflow threshold, the filter element is not flushed or soaked, and does not need to be cleaned. The controller can control the water purification equipment to work normally.

[0118] In the second case, the controller compares the clean water volume with the preset water threshold. When the clean water volume is greater than the first water threshold and less than or equal to the second water threshold, the controller has controlled the water of the first temperature to flush the filter element for the first flushing time, and soaked it for the first soaking time after flushing. After flushing and soaking the filter element, the filter element needs to be cleaned, specifically by controlling the water of the second temperature to clean it for the first cleaning time. When cleaning, water of a lower temperature can be used to save more energy.

[0119] In the third case, the controller compares the clean water volume with the preset water overflow threshold value. When the clean water volume is greater than the second water overflow threshold value and less than or equal to the third water overflow threshold value, the controller has controlled the water of the first temperature to flush the filter element for the second flushing time, and soak the filter element for the second soaking time after the flushing is completed. After flushing and soaking the filter element, the water of the second temperature can be controlled to clean the filter element for the second cleaning time.

[0120] In the fourth case, the controller compares the clean water volume with the preset water overflow threshold value. When the clean water volume is greater than the third water overflow threshold value, the controller has controlled the water of the first temperature to flush for the third flushing time, and soak for the third soaking time after the flushing is completed. After flushing and soaking the filter element, the water of the second temperature can be controlled to clean for the third cleaning time.

[0121] Exemplarily, when the amount of clean water is greater than the first water threshold and less than or equal to the second water threshold, the controller can control the normal temperature water pipeline and the waste water pipeline to open, and use normal temperature water to clean the filter element for 30 seconds; when the amount of clean water is greater than the second water threshold and less than or equal to the third water threshold, the controller can control the normal temperature water pipeline and the waste water pipeline to open, and use normal temperature water to clean the filter element for 75 seconds; when the amount of clean water is greater than the third water threshold, the controller can control the normal temperature water pipeline and the waste water pipeline to open, and use normal temperature water to flush the filter element for 105 seconds. Exemplarily, the first cleaning time can be set between 10 seconds and 60 seconds; the second cleaning time can be set between 60 seconds and 90 seconds; and the third cleaning time can be set between 90 seconds and 120 seconds.

[0122] In this embodiment, by comparing the amount of purified water with different preset water overflow thresholds, different comparison results are obtained. After the filter element is flushed and soaked, it is cleaned for different lengths of time to remove impurities precipitated from the filter element, which is beneficial to ensure the filtering effect of the filter element and further ensure the water purification efficiency of the water purification equipment.

[0123] In an exemplary embodiment, as shown in FIG. 6 , step 204 may further include steps 602 to 606 .

[0124] Step 602, when the purified water volume is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, control the water at a first temperature to flush the filter element of the water purification device at a first frequency for a first flushing time, and soak the filter element for a first soaking time.

[0125] Step 604, when the purified water volume is greater than the second water overflow threshold and less than or equal to the third water overflow threshold, control the water of the first temperature to flush the filter element of the water purification device at a second frequency for a second flushing time, and soak for a second soaking time.

[0126] Step 606, when the purified water volume is greater than the third water overflow threshold, control the water at the first temperature to flush the filter element of the water purification device at a third frequency for a third flushing time, and soak the filter element for a third soaking time.

[0127] The first frequency is lower than the second frequency, and the second frequency is lower than the third frequency. The three frequencies can be characterized as flushing and soaking once for each increase in the amount of clean water by a certain value, and the specific values ​​can be set manually and can be arbitrarily selected on the basis of meeting the above size restrictions, and are not limited here.

[0128] Specifically, in the first case, the controller compares the water purifier with the preset water overflow threshold. When the purified water volume is less than or equal to the first water overflow threshold, there is no need to flush, soak or clean the filter element. The controller can control the water purification equipment normally to meet the user's water needs.

[0129] In the second case, the controller compares the clean water volume with the preset water threshold. When the clean water volume is greater than the first water threshold and less than or equal to the second water threshold, the controller can control the water of the first temperature to flush and soak the filter element at the first frequency, that is, when the clean water volume increases by the value corresponding to the first frequency, the filter element is flushed for the first flushing time, and soaked for the first soaking time after flushing. Since the remaining service life of the filter element in this case is longer, the first frequency can be a smaller frequency, that is, the value corresponding to the first frequency is larger.

[0130] In the third case, the controller compares the clean water volume with the preset water threshold. When the clean water volume is greater than the second water threshold and less than or equal to the third water threshold, the controller can control the water of the first temperature to flush and soak the filter element at the second frequency, that is, when the clean water volume increases by the value corresponding to the second frequency, the filter element is flushed for the second flushing time, and soaked for the second soaking time after flushing. Since the remaining service life of the filter element in this case is moderate, the second frequency can be a frequency greater than the first frequency, that is, the value corresponding to the second frequency is less than the value corresponding to the first frequency.

[0131] In the fourth case, the controller compares the clean water volume with the preset water threshold. When the clean water volume is greater than the third water threshold, the controller can control the water of the first temperature to flush and soak the filter element at the third frequency, that is, when the clean water volume increases by the value corresponding to the third frequency, the filter element is flushed for the third flushing time, and soaked for the third soaking time after flushing. Since the remaining service life of the filter element in this case is short, the third frequency can be a frequency greater than the second frequency, that is, the value corresponding to the third frequency is less than the value corresponding to the second frequency.

[0132] Exemplarily, when the clean water volume is greater than the first water threshold and less than or equal to the second water threshold, the filter element is flushed, soaked and cleaned every time the clean water volume increases by 2,500 liters; when the clean water volume is greater than the second water threshold and less than or equal to the third water threshold, the filter element is flushed, soaked and cleaned every time the clean water volume increases by 1,500 liters; when the clean water volume is greater than the third water threshold, the filter element is flushed, soaked and cleaned every time the clean water volume increases by 500 liters. Optionally, the value corresponding to the first frequency can be between 3,000 liters and 2,000 liters; the value corresponding to the second frequency can be between 2,000 liters and 1,000 liters; and the value corresponding to the third frequency can be between 1,000 liters and 100 liters.

[0133] In this embodiment, by comparing the clean water volume with different preset water overflow thresholds, and controlling the filter element to be flushed, soaked and cleaned at different frequencies according to different comparison results, different degrees of regeneration are achieved, which is beneficial to ensuring the effectiveness and reliability of the filter element.

[0134] In an exemplary embodiment, step 204 can also be performed in another manner. As shown in FIG. 7 , step 204 includes steps 702 to 706 .

[0135] Step 702, when the purified water volume is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, control the water of the first temperature to flush the filter element of the water purification device at a fourth frequency for a preset flushing time, and soak the filter element for a preset soaking time.

[0136] Step 704, when the purified water volume is greater than the second water overflow threshold and less than or equal to the third water overflow threshold, control the water of the first temperature to flush the filter element of the water purification device at a fifth frequency for a preset flushing time, and soak the filter element for a preset soaking time.

[0137] Step 706, when the purified water volume is greater than the third water overflow threshold, control the water of the first temperature to flush the filter element of the water purification device at a sixth frequency for a preset flushing time, and soak the filter element for a preset soaking time.

[0138] Among them, the fourth frequency is lower than the fifth frequency, and the fifth frequency is lower than the sixth frequency. The three frequencies can be characterized as flushing and soaking once for each increase in the net water volume by a certain value. The specific values ​​can be set manually and can be arbitrarily selected on the basis of satisfying the above-mentioned size restrictions, and are not limited here. Furthermore, the fourth frequency can be equal to the first frequency, the fifth frequency can be equal to the second frequency, and the sixth frequency can be equal to the third frequency. In this embodiment, different net water volumes only change the frequency of flushing and soaking, and do not change the flushing duration and soaking duration.

[0139] Specifically, in the first case, the controller compares the water purifier with the preset water overflow threshold. When the purified water volume is less than or equal to the first water overflow threshold, there is no need to flush, soak or clean the filter element. The controller can control the water purification equipment to work normally to meet the user's water needs.

[0140] In the second case, the controller compares the clean water volume with the preset water overflow threshold. When the clean water volume is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, the water at the first temperature can be controlled to flush and soak the filter element at a fourth frequency. That is, every time the clean water volume increases by a value corresponding to the fourth frequency, the filter element is flushed for a preset flushing time and soaked for a preset soaking time after flushing.

[0141] In the third case, the controller compares the clean water volume with the preset water threshold, and when the clean water volume is greater than the second water threshold and less than or equal to the third water threshold, the water of the first temperature can be controlled to flush and soak the filter element at the fifth frequency, that is, when the clean water volume increases by the value corresponding to the fifth frequency, the filter element is flushed for a preset flushing time, and soaked for the preset soaking time after flushing. The fifth frequency is a frequency greater than the fourth frequency, and the value corresponding to the fifth frequency is less than the value corresponding to the fourth frequency.

[0142] In the fourth case, the controller compares the clean water volume with the preset water threshold. When the clean water volume is greater than the third water threshold, the controller can control the water of the first temperature to flush and soak the filter element at the sixth frequency, that is, when the clean water volume increases by the value corresponding to the sixth frequency, the filter element is flushed for a preset flushing time, and soaked for a preset soaking time after flushing. The sixth frequency can be a frequency greater than the fifth frequency, that is, the value corresponding to the sixth frequency is less than the value corresponding to the fifth frequency.

[0143] Exemplarily, when the clean water volume is greater than the first water threshold and less than or equal to the second water threshold, the filter element is flushed, soaked and cleaned every time the clean water volume increases by 2,500 liters; when the clean water volume is greater than the second water threshold and less than or equal to the third water threshold, the filter element is flushed, soaked and cleaned every time the clean water volume increases by 1,500 liters; when the clean water volume is greater than the third water threshold, the filter element is flushed, soaked and cleaned every time the clean water volume increases by 500 liters. The duration of each flushing, soaking and cleaning is the same, wherein the preset flushing duration is 30 seconds, the preset soaking duration is 15 minutes, and the preset cleaning duration is 30 seconds.

[0144] Optionally, the value corresponding to the fourth frequency can be between 3000 liters and 2000 liters; the value corresponding to the fifth frequency can be between 2000 liters and 1000 liters; the value corresponding to the sixth frequency can be between 1000 liters and 100 liters. The preset flushing time can be between 10 seconds and 60 seconds, the preset soaking time can be between 1 minute and 30 minutes, and the preset cleaning time can be between 10 seconds and 60 seconds.

[0145] Further, in an exemplary embodiment, based on FIG. 7 , after executing step 206 , that is, after flushing for the preset cleaning time, the water purification equipment control method further includes steps 802 to 806 .

[0146] Step 802, when the purified water volume is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, return to execute step 204 to control the first temperature water to flush the filter element of the water purification device for a preset flushing time, until the return execution times reach the first number threshold.

[0147] Step 804, when the purified water volume is greater than the second water overflow threshold and less than or equal to the third water overflow threshold, return to execute step 204 to control the first temperature water to flush the filter element of the water purification device for a preset flushing time, until the return execution times reach the second number threshold.

[0148] Step 806, when the purified water volume is greater than the third water flow threshold, return to step 204 to control the first temperature water to flush the filter element of the water purification device for a preset flushing time, until the return execution times reach the third number threshold.

[0149] The first number threshold is smaller than the second number threshold, and the second number threshold is smaller than the third number threshold. The first number threshold, the second number threshold, and the third number threshold can all be set manually and can be selected as any value as long as the size limit between the three is met, and there is no need to limit the specific value.

[0150] Specifically, in the first case, the controller compares the water purifier with the preset water overflow threshold. When the purified water volume is less than or equal to the first water overflow threshold, there is no need to flush, soak or clean the filter element, and the controller can control the water purification equipment to work normally.

[0151] In the second case, the controller compares the clean water volume with the preset water overflow threshold. When the clean water volume is greater than the first water overflow threshold and less than or equal to the second water overflow threshold, the controller flushes, soaks and cleans the filter element, and then returns to execute step 204 to flush, soak and clean the filter element again, and records the number of return executions. Until the number of return executions reaches the first number threshold, the controller does not return to step 204, and the control of the water purification device is completed.

[0152] In the third case, the controller compares the clean water volume with the preset water overflow threshold. When the clean water volume is greater than the second water overflow threshold and less than or equal to the third water overflow threshold, the controller flushes, soaks and cleans the filter element, and then returns to execute step 204 to flush, soak and clean the filter element again, and records the number of return executions. Until the number of return executions reaches the second number threshold, the controller does not return to step 204, and the control of the water purification device is completed.

[0153] In the fourth case, the controller compares the purified water volume with the preset water flow threshold. When the purified water volume is greater than the third water flow threshold, the controller flushes, soaks and cleans the filter element, and then returns to execute step 204 to flush, soak and clean the filter element again, and records the number of return executions. When the number of return executions reaches the third number threshold, the controller does not return to step 204, and the control of the water purification device is completed.

[0154] Exemplarily, when the clean water volume is greater than the first water threshold and less than or equal to the second water threshold, the filter element is continuously flushed, soaked and cleaned twice every time the clean water volume increases by 2,500 liters; when the clean water volume is greater than the second water threshold and less than or equal to the third water threshold, the filter element is continuously flushed, soaked and cleaned four times every time the clean water volume increases by 1,500 liters; when the clean water volume is greater than the third water threshold, the filter element is continuously flushed, soaked and cleaned eight times every time the clean water volume increases by 500 liters. Optionally, the first number threshold can be 1-2 times, the second number threshold can be 3-5 times, and the third number threshold can be 6-10 times.

[0155] In this embodiment, the filter element is repeatedly flushed, soaked and cleaned, and the process is repeated for different numbers of times depending on the amount of purified water, so that comprehensive cleaning and regeneration of the filter element is achieved. This is beneficial to ensuring the water purification efficiency of the water purification equipment, extending the service life of the filter element, reducing the frequency of filter element replacement by users, and improving the convenience of the water purification equipment.

[0156] Based on the same technical concept, the present application also provides a water purification device. In one embodiment, the water purification device is shown in Figure 1. The water purification device includes a hot water pipeline 102, a normal temperature water pipeline 104, a filter element 106, a water outlet pipeline 108, a waste water pipeline 110 and a controller (not shown in the figure). The hot water pipeline 102 and the normal temperature water pipeline 104 are both connected to the filter element 106, and the filter element 106 is connected to the waste water pipeline 110 and the water outlet pipeline 108.

[0157] Among them, the hot water pipeline 102 can input hot water to the filter element 106, and the normal temperature water pipeline 104 can input normal temperature water to the filter element 106. The above hot water and normal temperature water are both unfiltered raw water. After input into the filter element 106, the filter element 106 filters the hot water or normal temperature water, and the filtered pure water can be output through the water outlet pipeline 108 for users to take; when the water purification equipment cleans the filter element 106, the waste water flowing through the filter element 106 can be discharged through the waste water pipeline 110. The filter element 106 can be a core body obtained by arranging and combining ultrafiltration membrane, PP cotton and activated carbon / carbon rod, which is used to filter raw water.

[0158] The controller is connected to the hot water pipeline 102, the normal temperature water pipeline 104, the water outlet pipeline 108 and the waste water pipeline 110. Specifically, solenoid valves are provided on the hot water pipeline 102, the normal temperature water pipeline 104, the water outlet pipeline 108 and the waste water pipeline 110. Each solenoid valve is connected to the controller. The controller controls the opening and closing of the pipeline where each solenoid valve is located by controlling the switch of each solenoid valve, thereby realizing the water purification equipment control method recorded in each embodiment of the present application.

[0159] Furthermore, the water outlet pipe 108 is connected to the waste water pipe 110. On the basis that both the normal temperature water pipe 104 and the hot water pipe 102 include solenoid valves, the water outlet pipe 108 and the waste water pipe 110 may be provided with a solenoid valve only on the waste water pipe 110. Since the side of the water outlet pipe 108 away from the filter element 106 is connected to a faucet, the user can realize the output and cut-off of the water outlet pipe 108 by opening and closing the faucet.

[0160] In an exemplary embodiment, the water purification equipment may also include a flow meter arranged in the water outlet pipe 108, the flow meter is connected to the controller, and can detect the amount of clean water output by the water purification equipment, that is, the water flow rate actually purified by the water purification equipment, corresponding to the water flow rate filtered by the filter element 106, which can be used to estimate the service life of the filter element 106, so that the controller can control the water purification equipment based on the clean water volume.

[0161] In order to better understand the above solution, a detailed explanation is given below in conjunction with a specific embodiment.

[0162] In one embodiment, the water purification equipment is shown in FIG8 , and the water purification equipment includes a hot water pipeline, a normal temperature water pipeline, a filter element, a water outlet pipeline, a waste water pipeline and a controller (not shown in the figure), and a solenoid valve 2 is provided on the hot water pipeline for transmitting raw water 2 (hot water) to the pretreatment filter element, and a solenoid valve 1 is provided on the normal temperature water pipeline for transmitting raw water 1 (normal temperature water) to the pretreatment filter element, and a solenoid valve 3 is provided on the waste water pipeline for discharging waste water, and one end of the water outlet pipeline is connected to the pretreatment filter element, and the other end is connected to the water tap for users to take water. The flow meter is provided at the common end of the filter element connecting the waste water pipeline and the water outlet pipeline, and can record the amount of water flowing through the pretreatment filter element. The controller is connected to the solenoid valve 1, the solenoid valve 2 and the solenoid valve 3, and can judge the water flow state in the pipeline according to the opening and closing state of the solenoid valve, and analyze the amount of water flowing collected by the flow meter to obtain the amount of clean water therein. Among them, the pretreatment filter element is a filter element used to purify raw water, which can be a combination of ultrafiltration membrane, PP cotton and activated carbon / carbon rod.

[0163] The controller can be connected to the water tap. When the water tap is turned to the normal temperature water gear, solenoid valve 1 is opened, solenoid valve 2 and solenoid valve 3 are closed, and normal temperature water enters the pre-treatment filter element through solenoid valve 1, and then flows out of the water tap after passing through the flow meter after the pre-treatment filter element; when the water tap is turned to the hot water gear, solenoid valve 2 is opened, solenoid valve 1 and solenoid valve 3 are closed, and hot water enters the pre-treatment filter element through solenoid valve 2, and then flows out of the water tap after passing through the flow meter after the pre-treatment filter element. Among them, hot water is tap water heated by a water heater, which is used for daily water such as bathing and washing face, and the water temperature is generally set to 45-55℃. The temperature of normal temperature water changes with the temperature of the environment.

[0164] When the flow meter detects the designed water flow (preset water flow threshold), the water purification equipment executes the activated carbon regeneration control logic. After the user installs the machine, the user's water use time period is collected, and the time period t when the user uses less water is screened out based on the collected user usage time period. The activated carbon regeneration control is preferentially executed in time period t. The specific logic of the activated carbon regeneration control logic is as follows:

[0165] 1. Solenoid valve 1 is closed, solenoid valve 2 and solenoid valve 3 are opened at the same time, the water tap is closed, and the pre-treatment filter element is flushed. After the operation reaches the set time a, solenoid valve 2 and solenoid valve 3 are closed at the same time, and the hot water completely soaks the pre-treatment filter element.

[0166] 2. When the soaking reaches the set time b, solenoid valves 1 and 3 are opened, solenoid valve 2 is closed, the water tap is closed, and the pre-treatment filter element is cleaned. After the operation reaches the set time c, solenoid valves 1 and 3 are closed at the same time. In this step, the normal temperature water washes away the adsorbent precipitated during the thermal regeneration process, and the filter element regeneration is completed.

[0167] Among them, when the water passing capacity L1 < L ≤ L2, activated carbon regeneration is performed once every l1 (l1 < L2 - L1) of water passing, a takes the value of a1, b takes the value of b1, and c takes the value of c1; when the water passing capacity L2 < L ≤ L3, activated carbon regeneration is performed once every l2 (l2 < L3 - L2) of water passing, a takes the value of a2, b takes the value of b2, and c takes the value of c2; when the water passing capacity L ≥ L3, activated carbon regeneration is performed once every l3 of water passing, a takes the value of a3, b takes the value of b3, and c takes the value of c3.

[0168] Optionally, l1 > l2 > l3, l1 can take values from 3000L to 2000L, l2 can take values from 2000L to 1000L, l3 can take values from 1000L to 100L; a1 can take values from 10 to 60s, a2 can take values from 60 to 90s, a3 can take values from 90 to 120s; b1 can take values from 1 to 30min, b2 can take values from 30 to 60min, b3 can take values from 60 to 120min; c1 can take values from 10 to 60s, c2 can take values from 60 to 90s, c3 can take values from 90 to 120s.

[0169] Under another activated carbon regeneration control logic, the control method of the water purification device can be executed as follows:

[0170] When the water passing capacity L1 < L ≤ L2, activated carbon regeneration is continuously performed n1 times every l1 (l1 < L2 - L1) of water passing; when the water passing capacity L2 < L ≤ L3, activated carbon regeneration is continuously performed n2 times every l2 (l2 < L3 - L2) of water passing; when the water passing capacity L ≥ L3, activated carbon regeneration is continuously performed n3 times every l3 of water passing.

[0171] Optionally, l1 > l2 > l3, l1 can take values from 3000L to 2000L, l2 can take values from 2000L to 1000L, l3 can take values from 1000L to 100L; a takes values from 10 to 60s, b takes values from 1 to 30min, c takes values from 10 to 60s, n1 takes values from 1 to 2 times, n2 takes values from 2 to 5 times, and n3 takes values from 5 to 10 times.

[0172] In this embodiment, the activated carbon in the pretreatment filter element is regenerated by the thermal method through the hot water pipeline, and the pretreatment filter element is cleaned by using the normal temperature water pipeline. Different regeneration logics can be set in segments according to the change of the water passing capacity, and regeneration of different flushing, soaking and cleaning processes can be carried out, so as to extend the service life of the pretreatment filter element, solve the problem that the pretreatment filter element needs to be replaced frequently, and improve the user experience and the convenience of the water purification device.

[0173] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
