Technical Field
[0001] This application relates to the field of water purification equipment technology, and in particular to a water purification device, a water purification equipment control method, an apparatus, a computer device, a storage medium, and a computer program product. Background Technology
[0002] With the development of the water purification industry, reverse osmosis membranes are widely used in water purification equipment. However, during the standby process of water purification equipment, due to the high concentration of salt ions on the raw water side of the reverse osmosis membrane and the low concentration on the pure water side, driven by the concentration difference of salt ions on both sides, salt ions on the raw water side of the reverse osmosis membrane permeate to the pure water side. The longer the standby time, the more salt ions permeate, resulting in a higher salt ion content in the first cup of water produced after the water purification equipment has been standing for a period of time.
[0003] In traditional technology, water purification equipment is set with a fixed pure water recirculation mode to improve the first cup of water produced by the equipment after standing. However, the environments of water purification equipment vary in different regions, and the fixed pure water recirculation mode cannot flexibly meet the needs of improving the first cup of water in different regions. Summary of the Invention

[0017] When the duration of the water purification equipment's stop producing water reaches the current reflux standby time, the water purification equipment will be controlled to start the pure water reflux mode according to the current reflux running time.
[0018] In one embodiment, the process of determining the correspondence includes:

The terminology used in this application and in its specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0053] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. Furthermore, in the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if there is transmission of electrical signals or data between the connected objects.
[0054] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.
[0055] In one embodiment, such as Figure 1As shown, to improve the first cup of water produced after the water purifier has been left to stand, common water purifiers include a raw water inlet 101, a pressure stabilizing pump 102, a reverse osmosis membrane filter element 103, a wastewater solenoid valve 104, a wastewater outlet 105, a pure water outlet 106, a pure water reflux valve 107, and a check valve 108.
[0056] The raw water inlet 101 is used to inject raw water (unfiltered water that is not directly drinkable, such as tap water) into the water purification equipment. The pressure stabilizing pump 102 applies pressure to the water on the raw water side of the reverse osmosis membrane filter element 103, allowing water molecules and ionic minerals to pass through. The reverse osmosis membrane filter element 103 filters out most dissolved inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc., thus filtration of the raw water flowing into the reverse osmosis membrane filter element 103 into potable pure water.
[0057] The reverse osmosis membrane filter element 103 includes a filter element inlet, a first filter element pure water outlet, a second filter element pure water outlet, and a filter element wastewater outlet. The filter element inlet of the reverse osmosis membrane filter element 103 can be connected to the raw water inlet 101 via a pressure stabilizing pump 102. The filter element inlet of the reverse osmosis membrane filter element 103 can also be connected to the pure water outlet 106 via a pure water return pipeline. The filter element wastewater outlet of the reverse osmosis membrane filter element 103 is connected to the wastewater outlet 105 via a wastewater solenoid valve 104. A pure water return valve 107 and a check valve 108 are used to construct the pure water return pipeline in the water purification equipment. The pure water return valve 107 controls the flow in the pure water return pipeline, and the check valve 108 ensures that the water flow in the pure water return pipeline follows the pure water return direction. During the operation of the water purification equipment, the equipment can discharge the wastewater filtered by the reverse osmosis membrane filter element 103 through the filter element wastewater inlet, wastewater solenoid valve, and wastewater outlet. A portion of the filtered pure water is used for pure water reflux through the first filter element pure water inlet, and potable pure water is provided to the user through the second filter element pure water inlet.
[0058] In one embodiment, in Figure 1 Based on existing water purification equipment, this paper presents a water purification system that can flexibly meet the needs of different regions for improving the first cup of water, including:
[0059] Pure water return pipeline, reverse osmosis membrane filter element, and temperature detection device; the reverse osmosis membrane filter element has a filter element inlet, a first filter element pure water outlet, and a second filter element pure water outlet;
[0060] The filter element inlet is connected to the first filter element's pure water outlet via a pure water return pipeline; the filter element inlet is connected to the raw water inlet; and the second filter element's pure water outlet is connected to the pure water outlet.
[0061] Temperature sensing devices are used to detect the water temperature in water purification equipment.
[0062] The temperature detection device includes, but is not limited to, various devices capable of detecting water temperature and converting the detected water temperature into a usable output signal. The temperature detection device is installed inside the water purification equipment. The water purifier also includes a controller (not shown in the figure).
[0063] Optionally, during the operation of the water purification equipment, the controller in the water purification equipment can automatically adjust the pure water reflux mode according to the real-time water temperature detected by the temperature detection device. The controller in the water purification equipment can be used to control the operation of the water purification equipment. The controller can respond to user commands and control the operation of the water purification equipment according to user instructions, or it can automatically control the operation of the water purification equipment according to a preset program.
[0064] For example, such as Figure 2 As shown, in Figure 1 Based on this, taking the connection between the filter inlet and the raw water inlet 101 via a temperature detection device 109 as an example, a water purification device including a temperature detection device is provided. Figure 2 The temperature sensing device 109 in the water purifier can be used to detect the temperature of the raw water in the water purifier. The controller in the water purifier can use the raw water temperature detected by the temperature sensing device 109 as the water temperature of the water flowing through the water purifier, thereby determining the pure water reflux mode that matches the water temperature. The connection sequence of the pure water reflux valve 107 and the check valve 108 in the pure water reflux pipeline is not limited to... Figure 2 The sequence shown can also be as follows: the pressure stabilizing pump 102 is connected to the second filter element pure water port of the reverse osmosis membrane filter element 103 through the pure water return valve 107 and the check valve 108.
[0065] For example, such as Figure 3 As shown, in Figure 1 Based on this, taking the example of connecting the filter element inlet to the raw water inlet 101 and the pure water outlet of the first filter element respectively through the temperature detection device 109, a water purification device including a temperature detection device is provided. Figure 3 The temperature sensing device 109 in the filter cartridge can be used to detect the temperature of the mixed water flowing into the filter cartridge inlet, wherein the mixed water includes raw water and returned pure water. Furthermore, the controller in the water purification equipment can use the temperature of the mixed water detected by the temperature sensing device as the temperature of the water flowing through the water purification equipment, thereby determining a pure water return mode that matches the water temperature. In the pure water return pipeline, the connection sequence of the pure water return valve 107 and the check valve 108 is not limited to... Figure 3 The order shown.
[0066] For example, such as Figure 4 As shown, in Figure 1Based on this, taking the connection of the second filter element's pure water outlet to the pure water outlet 106 via a temperature detection device 109 as an example, a water purification device including a temperature detection device is provided. Figure 4 The temperature sensing device 109 can be used to detect the temperature of the pure water produced by the water purification equipment. Furthermore, the controller in the water purification equipment can use the temperature of the pure water detected by the temperature sensing device as the temperature of the water flowing through the water purification equipment, thereby determining the pure water reflux mode that matches the water temperature. The temperature sensing device 109 can also be installed in the pure water reflux pipeline, also for detecting the temperature of the pure water produced by the water purification equipment; this will not be elaborated further here. In the pure water reflux pipeline, the connection order of the pure water reflux valve 107 and the check valve 108 is not limited to... Figure 4 The order shown.
[0067] For example, such as Figure 5 As shown, in Figure 1 Based on this, taking the connection between the filter cartridge wastewater outlet and the wastewater outlet 105 via a temperature detection device 109 as an example, a water purification device including a temperature detection device is provided. Figure 5 The temperature sensing device 109 can be used to detect the temperature of the wastewater generated by the water purification equipment. Furthermore, the controller in the water purification equipment can use the wastewater temperature detected by the temperature sensing device as the temperature of the water flowing through the purification equipment, thereby determining a pure water reflux mode that matches the water temperature. In the pure water reflux pipeline, the connection sequence of the pure water reflux valve 107 and the check valve 108 is not limited to... Figure 5 The order shown.
[0068] The aforementioned water purification equipment, including a temperature detection device, takes into account the different environments in which different water purification devices are located. The environment affects the water temperature in the water purification device, and the water temperature further affects the permeation of salt ions on both sides of the reverse osmosis membrane in the water purification device. Therefore, the water temperature in the water purification device can be detected by the temperature detection device, so that the water purification device can automatically and flexibly adjust the pure water recirculation mode according to the water temperature. This allows the water purification device to automatically and flexibly execute different pure water recirculation modes according to the environment of the area, so that the water purification device can flexibly meet the first cup of water improvement needs of different regions.
[0069] The water purification equipment control method provided in this application embodiment can be applied to... Figures 2 to 5In any of the water purification devices shown in the diagram, specifically, the controller in the water purification device can connect to the temperature detection device to obtain the current water temperature collected by the temperature detection device. Based on the correspondence between water temperature ranges and reflux parameters, it determines the current reflux parameters that match the current water temperature range. These current reflux parameters include the current reflux standby time and the current reflux running time. Furthermore, when the controller detects that the duration of the water purification device's water production stoppage reaches the current reflux standby time, the controller can control the water purification device to start the pure water reflux mode according to the current reflux running time.
[0070] In one exemplary embodiment, such as Figure 6 As shown, a water purification equipment control method is provided, which is applied to... Figures 2 to 5 The following explanation uses the controller of any water purification device shown in any of the figures as an example, including steps 602 to 608. Wherein:
[0071] Step 602: Obtain the current water temperature collected by the temperature detection device in the water purification equipment.
[0072] The current water temperature refers to the real-time water temperature.
[0073] Optionally, the controller in the water purification equipment can obtain the current water temperature collected by the temperature detection device connected to the controller.
[0074] Step 604: Based on the correspondence between water temperature range and recirculation parameters, determine the current recirculation parameters that match the current water temperature range; the current recirculation parameters include the current recirculation standby time and the current recirculation running time.
[0075] Specifically, the reflux standby time refers to the time when the water purifier stops producing water for a period of time equal to the reflux standby time, at which point the controller will activate the pure water reflux mode. The reflux runtime refers to the runtime of a single pure water reflux cycle.
[0076] Optionally, the controller can first determine the current water temperature range, and then determine the current recirculation parameters that match the current water temperature range based on the correspondence between the water temperature range and the recirculation parameters.
[0077] For example, assume the following correspondence exists between the water temperature range and the reflux parameters: if the water temperature ≥ the first preset water temperature, the reflux standby time = T1, and the reflux running time = T2; if the first preset water temperature > the water temperature ≥ the second preset water temperature, the reflux standby time = T3, and the reflux running time = T4; if the second preset water temperature > the water temperature, the reflux standby time = T5, and the reflux running time = T6. Wherein, the first preset water temperature > the second preset water temperature > the third preset water temperature. The higher the water temperature, the easier it is for salt ions from the raw water side of the reverse osmosis membrane filter to permeate to the pure water side. Therefore, T1 < T3 < T5, T2 > T4 > T6. Furthermore, when the current water temperature is ≥ the first preset water temperature, the controller can control the water purifier to operate in pure water recirculation mode for a duration of T1 when the water purifier stops producing water, with a running time of T2; when the first preset water temperature > the water temperature ≥ the second preset water temperature, the controller can control the water purifier to operate in pure water recirculation mode for a duration of T3 when the water purifier stops producing water, with a running time of T4; when the second preset water temperature > the water temperature, the controller can control the water purifier to operate in pure water recirculation mode for a duration of T5 when the water purifier stops producing water, with a running time of T6.
[0078] Step 606: When the duration of the water purification equipment's stop producing water reaches the current reflux standby time, control the water purification equipment to start the pure water reflux mode according to the current reflux running time.
[0079] The water purification equipment may also include a timer, which is connected to a controller in the water purification equipment. The controller can be used to control the timer to start and stop timing, as well as to receive and analyze the timing data of the timer.
[0080] Optionally, when the water purification equipment stops producing water, the controller in the water purification equipment can automatically control the timer to start timing. When the controller determines that the duration of the water purification equipment stopping water production has reached the current reflux standby time, the controller can control the water purification equipment to start the pure water reflux mode according to the current reflux running time. When the running time of the pure water reflux mode reaches the current reflux running time, the controller can control the water purification equipment to stop the pure water reflux mode.
[0081] If the controller detects that the duration of the water purification device's water production stoppage has not reached the current recirculation standby time, for example, if the water purification device is restarted in water production mode before the duration of the water production stoppage reaches the current recirculation standby time, the controller can execute step 608 and not control the water purification device to start the pure water recirculation mode.
[0082] In the above-mentioned water purification equipment control method, considering that the water temperature in water purification equipment varies due to environmental influences in different regions, and that the water temperature in the water purification equipment affects the permeation of water salt ions on both sides of the reverse osmosis membrane in the water purification equipment, the current water temperature collected by the temperature detection device in the water purification equipment can be obtained first. Based on the correspondence between the water temperature range and the reflux parameters, the current reflux parameters matching the current water temperature range can be determined. The current reflux parameters include the current reflux standby time and the current reflux running time. When the duration for which the water purification equipment stops producing water reaches the current reflux standby time, the water purification equipment is controlled to start the pure water reflux mode according to the current reflux running time. Thus, the pure water reflux mode of the water purification equipment can be flexibly selected according to the water temperature under the influence of the environment in the region, thereby flexibly meeting the first cup water improvement needs of different regions.
[0083] In an exemplary embodiment, the process of determining the correspondence between the water temperature range and the reflux parameters includes:
[0084] Determine multiple water temperature test ranges and multiple reflux test parameters;
[0085] For each water temperature test range, the desalination rate of the purified water produced by the water purification equipment under each reflux test parameter is obtained;
[0086] The reflux test parameters that enable the water purification equipment to achieve the set desalination rate and minimize water consumption are determined as the reflux test parameters corresponding to the water temperature test range.
[0087] The data of the reflow test parameters corresponding to each water temperature test range are summarized to obtain the correspondence between the water temperature range and the reflow parameters.
[0088] The backflow test parameters include: the backflow standby time to be tested, the backflow runtime to be tested, and the backflow interval time to be tested. Specifically, the backflow standby time refers to the time the water purifier stops producing water, at which point the controller will activate the pure water backflow mode. The backflow runtime refers to the duration of a single pure water backflow cycle. The backflow interval time refers to the time the water purifier remains stationary after stopping the pure water backflow mode; if this duration is reached, the controller will restart the pure water backflow mode. Furthermore, the backflow parameters for restarting the pure water backflow mode need to be re-determined by the controller based on the real-time water temperature.
[0089] The desalination rate can be configured according to drinking water standards. The correspondence between water temperature and reflux parameters varies across different water purification equipment models. To determine the correspondence between water temperature range and reflux parameters for each model, the controller in any water purification unit of that model can analyze and determine the correspondence based on test data uploaded by R&D personnel. This allows controllers in other water purification units of the same model to directly and quickly use the determined correspondence, and then, combined with their respective detected real-time water temperatures, rapidly and adaptively adjust the pure water reflux mode of their respective water purification units.
[0090] Optionally, taking a controller used to determine the correspondence between water temperature ranges and reflux parameters based on test data uploaded by R&D personnel as an example, the controller can first determine multiple water temperature test ranges and multiple reflux test parameters based on the test data uploaded by R&D personnel. For each water temperature test range, the controller can obtain the desalination rate of the purified water produced by the water purification equipment under each reflux test parameter from the test data. The reflux test parameter that makes the desalination rate of the purified water produced by the water purification equipment reach the set desalination rate and minimizes water consumption is determined as the reflux test parameter corresponding to the water temperature test range. Then, the data of the reflux test parameters corresponding to each water temperature test range are summarized to obtain the correspondence between the water temperature range and the reflux parameter.
[0091] For example, if the controller determines, based on the test data uploaded by the R&D personnel, that in the water temperature range of "water temperature ≥ first preset water temperature", the desalination rate of the first cup of water produced by the X model water purifier meets the standard under the two sets of backflow test parameters: "(1) backflow standby time t1, backflow running time t2, backflow interval time t3" and "(2) backflow standby time t4, backflow running time t5, backflow interval time t6", and t1> t4, t2< t5, t3> t6, considering that the backflow parameters in (1) can make the backflow frequency lower and the single backflow time shorter, which can save more water resources, the controller can use (1) as the backflow parameters for the water temperature range of "water temperature ≥ first preset water temperature" of this model of water purifier. Furthermore, when the X-type water purifier needs to execute the pure water recirculation mode, if the controller in the X-type water purifier detects that the current water temperature is ≥ the first preset water temperature, the controller can control the X-type water purifier to execute the pure water recirculation mode according to the recirculation parameters in (1).
[0092] In this embodiment, for each model of water purification equipment, for each water temperature range, the reflux parameter that enables the water produced by the water purification equipment to achieve the required desalination rate and minimize water consumption within that water temperature range is determined. This results in the correspondence between the water temperature range and the reflux parameter for each model of water purification equipment. This allows the controller of the subsequent water purification equipment to quickly and adaptively adjust the pure water reflux mode of the water purification equipment according to the real-time water temperature in the water purification equipment, based on the precisely determined correspondence.
[0093] Furthermore, for each water temperature range, this embodiment determines the reflux test parameter with the lowest water consumption as the final reflux parameter. Compared with the pure water reflux mode with fixed reflux parameters in traditional technology, this can minimize the water consumption of pure water reflux while ensuring the effect of pure water reflux, which is conducive to saving water resources.
[0094] In an exemplary embodiment, the desalination rate of the purified water produced by the water purification equipment under each reflux test parameter is obtained, including:
[0095] For each reflux test parameter, obtain the salt content of each cup of purified water produced by the water purification equipment under the reflux test parameter;
[0096] Based on the salt content of the raw water in the water purification equipment and the salt content of each of the multiple cups of purified water, the desalination rate of each of the multiple cups of purified water is determined.
[0097] The minimum desalination rate is used as the desalination rate of the purified water produced by the water purification equipment under the reflux test parameters.
[0098] The desalination rate refers to the percentage of anions and cations removed from water during the chemical or ion exchange process. In this embodiment, it refers to the salt removal rate of the reverse osmosis membrane.
[0099] Optionally, for each reflux test parameter, the controller can obtain the salt content of each of the multiple cups of purified water produced by the water purifier under the reflux test parameters from the test data. During the data collection process, researchers can first measure the salt content of the raw water. For each reflux test, after controlling the water purifier to produce water for a period of time, the controller controls the water purifier to execute a complete pure water reflux mode according to the reflux test parameters. Then, the first cup of purified water produced by the water purifier is collected, and the process of collecting the first cup of purified water is repeated to obtain multiple cups of purified water under the given reflux test parameters. The salt content of each cup of purified water is then measured. Finally, the salt content of the raw water and the salt content of each cup of purified water under the given reflux test parameters are uploaded.
[0100] Furthermore, the controller can calculate and determine the desalination rate of each of the multiple cups of purified water based on the salt content of the raw water in the water purification equipment and the salt content of each cup of purified water. The minimum desalination rate is then used as the desalination rate of the purified water produced by the water purification equipment under the reflux test parameters. Using the same method, for each water temperature range, the controller can determine the desalination rate of the purified water produced by the water purification equipment under each reflux test parameter.
[0101] For example, let C be the salt content of a glass of purified water. p (Unit: mg / L, milligrams per liter), the salinity of the raw water is C. f Taking (unit: mg / L, milligrams per liter) as an example, the controller can specifically determine the desalination rate R of the purified water using formula (1). n (Unit: %, percentage):
[0102] (1)
[0103] In this embodiment, for each reflux test parameter, the desalination rate under that reflux test parameter can be accurately determined based on multiple samples of the first cup of purified water produced under that reflux test parameter. Furthermore, in this embodiment, the minimum desalination rate is used as the desalination rate under that reflux test parameter. This can be understood as using the worst-case pure water reflux effect under that reflux test parameter as the basis for evaluating that reflux test parameter, ensuring that the worst-case pure water reflux effect corresponding to each water temperature range can also achieve the set desalination rate. This ensures that when the pure water reflux mode is subsequently executed according to the correspondence between the water temperature range and the reflux parameter, the first cup of water can be significantly improved.
[0104] In one embodiment, the current reflux parameter also includes the current reflux interval duration, and the above-mentioned water purification equipment control method further includes:
[0105] When the water purification equipment stops the pure water recirculation mode, the duration of continuous static time of the water purification equipment is timed; continuous static time indicates that the water purification equipment has not started the water production mode or the pure water recirculation mode.
[0106] When the continuous settling time reaches the current reflux interval, the update reflux parameters that match the water temperature range of the update water temperature are determined based on the real-time updated water temperature collected by the temperature detection device.
[0107] According to the updated reflux parameters, control the water purification equipment to start the pure water reflux mode.
[0108] Among them, the duration of continuous quiescent time reaching the current reflux interval indicates that the water purification equipment has been quiescent for too long and needs to be restarted in the pure water reflux mode in a timely manner.
[0109] Optionally, when the water purification equipment stops the pure water reflux mode, the controller can control the timer to count the continuous settling time of the water purification equipment. When the controller detects that the continuous settling time of the water purification equipment has reached the current reflux interval, the controller can obtain the updated water temperature collected in real time by the temperature detection device, determine the water temperature range of the updated water temperature, and then, based on the correspondence between the water temperature range and the reflux parameters, determine the updated reflux parameters that match the water temperature range of the updated water temperature, and then control the water purification equipment to start the pure water reflux mode according to the updated reflux parameters.
[0110] In this embodiment, after the water purification equipment stops the pure water recirculation mode, the controller will detect in real time whether the continuous static time of the water purification equipment is too long. When the continuous static time of the water purification equipment reaches the current recirculation interval, the controller will automatically and adaptively select the updated recirculation parameters that match the real-time water temperature in the water purification equipment, and then control the water purification equipment to start the purified water recirculation according to the updated recirculation parameters.
[0111] In one embodiment, the water purification equipment control method further includes:
[0112] If the water purification equipment stops pure water reflux and the continuous standing time does not reach the current reflux interval, and the water purification equipment starts water production mode, when the water purification equipment stops water production, the updated water temperature collected in real time by the temperature detection device is obtained.
[0113] The water purification equipment is controlled to start the pure water recirculation mode according to the update recirculation parameters that match the update water temperature.
[0114] Optionally, when the water purifier stops the pure water reflux mode, the controller can control the timer to count the continuous settling time of the water purifier. If the continuous settling time of the water purifier does not reach the current reflux interval, the water purifier starts the water production mode. That is, if the continuous settling time after the water purifier stops pure water reflux does not reach the current reflux interval, and the water purifier starts the water production mode, when the water purifier stops producing water, the controller can obtain the updated water temperature collected in real time by the temperature detection device, and control the water purifier to run pure water reflux according to the updated reflux parameters matched with the updated water temperature.
[0115] For example, assuming the update reflux parameters include update reflux standby time t7, update reflux runtime t8, and update reflux interval time t9, the controller can determine whether the water purification device has stopped producing water for t7 after it finishes production. If so, it controls the water purification device to run in pure water reflux mode for t8. Furthermore, after the water purification device stops pure water reflux, the controller can continue to determine whether the continuous settling time of the water purification device has reached t9. If so, it controls the water purification device to restart pure water reflux based on the real-time water temperature. If the water purification device was started in water production mode before this time, it will restart pure water reflux based on the real-time water temperature after production ends.
[0116] In this embodiment, after the water purifier completes the pure water recirculation mode, the controller will monitor the continuous static time of the water purifier in real time. If the static state of the water purifier is broken before the continuous static time reaches the current recirculation interval, such as when the water purifier is activated to produce water, the controller will determine the recirculation parameters adapted to the real-time water temperature based on the real-time water temperature of the water purifier, and then control the water purifier to restart the pure water recirculation.
[0117] In one embodiment, such as Figure 7 The diagram shows a flow chart of another water purification equipment control method, which mainly includes the following steps:
[0118] Step 702: Determine multiple water temperature test ranges and multiple reflux test parameters;
[0119] Step 704: For each reflux test parameter under each water temperature test range, obtain the salt content of each cup of purified water produced by the water purification equipment under the reflux test parameter.
[0120] Step 706: Based on the salt content of the raw water in the water purification equipment and the salt content of each of the multiple cups of purified water, determine the desalination rate of each of the multiple cups of purified water.
[0121] Step 708: The minimum desalination rate is taken as the desalination rate of the purified water produced by the water purification equipment under the reflux test parameters;
[0122] Step 710: The reflux test parameters that enable the desalination rate of the purified water produced by the water purification equipment to reach the set desalination rate and minimize water consumption are determined as the reflux test parameters corresponding to the water temperature test range.
[0123] Step 712: Summarize the data of the reflux test parameters corresponding to each water temperature test range to obtain the correspondence between the water temperature range and the reflux parameters;
[0124] Step 714: Obtain the current water temperature from the temperature detection device in the water purification equipment;
[0125] Step 716: Based on the correspondence between water temperature range and recirculation parameters, determine the current recirculation parameters that match the current water temperature range; the current recirculation parameters include the current recirculation standby time and the current recirculation running time.
[0126] When the duration of the water purification equipment's stop producing water reaches the current backflow standby time, step 718 is executed, and the water purification equipment is controlled to start the pure water backflow mode according to the current backflow running time; otherwise, step 720 is executed, and the water purification equipment is not controlled to start the pure water backflow mode.
[0127] When the water purification equipment stops the pure water recirculation mode, step 722 is executed to time the continuous static time of the water purification equipment; otherwise, return to step 718; wherein, continuous static time indicates that the water purification equipment has not started the water production mode or the pure water recirculation mode.
[0128] When the continuous settling time reaches the current reflux interval time, step 724 is executed to determine the update reflux parameters that match the water temperature range of the update water temperature based on the real-time updated water temperature collected by the temperature detection device.
[0129] Step 726: According to the updated reflux parameters, control the water purification equipment to start the pure water reflux mode;
[0130] If the continuous settling time after the water purification equipment stops pure water reflux does not reach the current reflux interval time, and the water purification equipment starts water production mode, then execute step 728, when the water purification equipment stops water production, and obtain the updated water temperature collected in real time by the temperature detection device; then execute steps 724 and 726 in sequence.

[0132] Based on the same inventive concept, this application also provides a water purification equipment control device for implementing the above-mentioned water purification equipment control method. The solution provided by this device is similar to the solution described in the above-described method. Therefore, the specific limitations of one or more embodiments of the water purification equipment control device provided below can be found in the limitations of the water purification equipment control method above, and will not be repeated here.

[0137] The aforementioned water purification equipment control device takes into account the environmental influences on water purification equipment in different regions, which can result in varying water temperatures.

[0141] In one embodiment, the pure water recirculation restart module in the water purification equipment control device is further used to acquire the updated water temperature collected in real time by the temperature detection device when the water purification equipment stops producing water, and to control the water purification equipment to start the pure water recirculation mode according to the updated recirculation parameters that match the updated water temperature.
