Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a control method, device, water purification equipment, and storage medium for water purification equipment. Background Technology

[0002] As living standards improve, consumers have increasingly stringent requirements for the quality and taste of drinking water, and the functions of household water purification equipment are also becoming more and more diverse. Water purification equipment that integrates cooling, heating, filtration, and mineral addition functions and can make water and ice is welcomed by the market. However, there are still shortcomings in the water production control methods of current water purification equipment. Under the diverse water demand of users, water purification equipment has difficulty in reasonably controlling the control process of cooling, heating, and other stages, resulting in inconsistent water output time, which leads to unstable water extraction time and long waiting time for users. Summary of the Invention

[0003] This invention provides a water purification equipment control method, device, water purification equipment, and storage medium to solve the problems of unstable water collection time and long waiting time for users.

[0004] In a first aspect, the present invention provides a method for controlling a water purification device, the method comprising: In response to the triggered water intake command, determine the target water output corresponding to the water intake command and obtain the cumulative water intake within the preset water production cycle and the unflushed time from the last flushing action to the current time; Calculate the water production demand based on the target water output and cumulative water intake; Based on the water demand and the duration of non-rinsing, the actions to be performed by the water purification equipment are determined, and the operation of the water purification equipment is controlled based on these actions.

[0005] This invention adds the target water output to the cumulative water intake within the current cycle to obtain the water production demand, representing the total water production required up to the current time in the current cycle. Furthermore, it uses the water production demand and the unrinsed time as inputs to determine the action to be executed, and controls the operation of the water purification equipment based on this action. By incorporating the cumulative water intake into the demand, the actual water production load of the filter cartridge can be comprehensively reflected. Combined with the unrinsed time, the rinsing decision no longer relies solely on a single time factor but is dynamically linked to the current water production demand. This facilitates the determination of rinsing periods and periods where rinsing is unnecessary, thereby effectively shortening the waiting time occupied by unnecessary rinsing while ensuring water quality, and improving water intake efficiency. It achieves the effect of adaptively adjusting the rinsing period according to actual operating conditions, stabilizing the user's water intake time, shortening the user's waiting time before water intake, and improving user satisfaction.

[0006] In one optional implementation, the water production demand is calculated based on the target water output and cumulative water intake, including: The water demand is determined by calculating the sum of the target water output and the cumulative water intake.

[0007] This invention determines flushing based on the total water demand and the duration of non-flushing, enabling proactive reduction of flushing according to different situations. This effectively reduces waiting time and water consumption due to unnecessary flushing while ensuring water quality safety, and improves water intake response speed.

[0008] In one optional implementation, the actions of the water purification equipment are determined based on the water demand and the duration of non-rinsing, including: Based on the relationship between water demand and preset water production threshold, and the relationship between unflushing time and preset maximum allowable unflushing time, the actions to be performed by the water purification equipment are determined.

[0009] This invention compares water production demand with a threshold and unflushed time with the maximum allowable time to comprehensively determine the operation of the water purification equipment. This allows the equipment to make dynamic decisions based on actual water production demand and unflushed time, avoiding unnecessary waiting and waste caused by fixed-cycle flushing. When water production demand is low and the intervals are short, the flushing frequency is reduced, saving water and electricity and shortening the time before water is dispensed. At the same time, it reduces the risk of filter clogging in the water purification equipment, extends the maintenance cycle, and improves the overall user experience.

[0010] In one optional implementation, the actions of the water purification equipment are determined based on the relationship between the water demand and a preset water production threshold, and based on the relationship between the unflushing time and a preset maximum allowable unflushing time, including: When the water demand is greater than or equal to the preset water production threshold and the unflushing time is less than the preset maximum allowable unflushing time, the water purification equipment is determined to perform a flushing action. When the water demand is less than the preset water production threshold and the unflushing time is greater than or equal to the preset maximum allowable unflushing time, the water purification equipment is determined to perform a flushing action. When the water demand is determined to be less than the preset water production threshold and the unflushing time is less than the preset maximum allowable unflushing time, or when the water demand is determined to be greater than or equal to the preset water production threshold and the unflushing time is greater than or equal to the preset maximum allowable unflushing time, the water purification equipment is determined to perform a water production action.

[0011] This invention determines the water production demand based on the sum of the target water output and the cumulative water intake; further, it determines the action to be executed based on the relationship between the water production demand and the preset water production threshold, as well as the relationship between the unflushing time and the preset maximum allowable unflushing time; it controls the operation of the water purification equipment according to the executed action; by combining the water production demand and the unflushing time, flushing is only initiated when the demand has reached the threshold or the time has exceeded the limit, avoiding unnecessary flushing when both are low, thereby effectively reducing flushing time and water and electricity consumption, and timely cleaning when there is a high demand for water production or the unflushing time is too long to ensure the filter cartridge efficiency and water safety, while further reducing the energy consumption of the water purification equipment caused by frequent start-stop of the equipment, reducing mechanical wear, and improving the overall water intake response speed of the water purification equipment.

[0012] In an optional implementation, after determining the target water output corresponding to the selected water intake level in response to receiving the selected water intake level, the method further includes: Obtain the water intake temperature set at the water intake level, and determine the water temperature difference between the outlet water temperature and the water intake temperature, where the outlet water temperature is the water temperature at the outlet of the water purifier. When the outlet water temperature difference is determined to be greater than or equal to the preset temperature difference value, the action to be performed by the water purification equipment is determined to be a flushing action; When the outlet water temperature difference is determined to be less than the preset temperature difference value, the water purification equipment is determined to perform a water production action.

[0013] This invention obtains the water intake temperature set at the water intake level and determines the temperature difference between the outlet water temperature and the intake water temperature. When the outlet water temperature difference is greater than or equal to the preset temperature difference value, a flushing action is performed; when the outlet water temperature difference is less than the preset temperature difference value, a water production action is performed. By judging the temperature difference, it can be determined that when the outlet water temperature deviates significantly from the set value, the interval between two water intakes is too long and the pipeline needs to be flushed first; when the temperature difference is small, it is determined that the interval between two water intakes is too short and water can be produced directly, saving unnecessary flushing time and water waste. This ensures the temperature adjustment response speed, reduces water and energy consumption, and improves the overall comfort of temperature-controlled water intake.

[0014] In one alternative implementation, after determining the actions of the water purification equipment based on water demand and unrinsed time, the method further includes: Calculate the target water intake time based on the target water output; The flushing start time is calculated based on the preset single flushing time, the preset single water production time, and the target water intake time. The flushing of the water purification equipment is controlled based on the flushing start time.

[0015] This invention calculates the target water intake time based on the target water output, and then calculates the flushing start time based on the preset single flushing time, preset single water production time, and target water intake time. Furthermore, it controls the operation of the water purification equipment based on the execution action. By comprehensively calculating the flushing start time with the time required for water production and water intake, the flushing action can be arranged in an appropriate window that is parallel to or precedes water production, avoiding the extra extension of the overall water intake process due to unreasonable flushing timing, thereby reducing user waiting time. At the same time, it ensures that the three actions of flushing, water production, and water intake are closely linked, reducing equipment idling and repeated start-stop, and improving operational continuity and efficiency.

[0016] In one optional embodiment, the water purification device further includes an ice-making water circuit, and the method further includes: In response to the triggered ice-making water command, determine the target ice-making water volume corresponding to the ice-making water command and obtain the cumulative ice-making water volume within the preset ice-making water cycle; Calculate the ice-making water demand based on the target ice-making water volume and the cumulative ice-making water volume; Control the water purification equipment to start discharging water, and when it is determined that the demand for ice-making water is greater than the preset ice-making water threshold, execute the flushing action; Alternatively, in response to monitoring that the current water volume is less than a preset minimum water volume threshold during the water intake process, the water purification equipment is controlled to start replenishing water, and a flushing action is performed during the water replenishment process.

[0017] This invention determines the target ice-making water volume and obtains the cumulative ice-making water volume based on the ice-making water command, and calculates the ice-making water demand accordingly; it controls the water purification equipment to start discharging water, and performs a flushing action when the demand exceeds a preset ice-making water volume threshold; simultaneously, if the current water volume is detected to be less than a preset minimum water volume threshold during the water dispensing process, it controls water replenishment and performs flushing during the water replenishment process; by triggering flushing through the demand threshold, flushing can be carried out in a timely manner when the ice-making water volume is high, ensuring the quality of the ice water; at the same time, the flushing is completed simultaneously with the water replenishment process when the water volume is insufficient, avoiding the need for separate extra flushing time, reducing user waiting time, and reducing the energy consumption of frequent water pump start-stop. Overall, it not only improves the safety of ice-making water, but also optimizes the timeliness of the flushing action.

[0018] In one alternative implementation, the method further includes: Get the current water usage period; When it is determined that the current water usage period is during a peak water usage period, the preset water production threshold is lowered; When it is determined that the current water usage period is in an off-peak period, the preset water production threshold is increased, where the water consumption during peak periods is greater than the water consumption during off-peak periods.

[0019] This invention obtains the current water usage period, lowers the preset water production threshold during peak water usage periods, and raises the preset water production threshold during off-peak water usage periods, wherein the water consumption during peak periods is greater than that during off-peak periods. By lowering the threshold during peak periods, the equipment can produce water and flush more actively in advance, ensuring the water supply and output speed during intensive water collection. By raising the threshold during off-peak periods, unnecessary water production and flushing frequency is reduced, saving water and electricity, reducing filter element wear and operating noise, achieving on-demand adjustment, and improving user experience.

[0020] In one optional embodiment, the water purification device further includes a hot water circuit and an ice water circuit, and the method further includes: Based on the water intake command, the water intake demand is determined, and when the water intake demand includes hot water demand and ice water demand, the first flushing time corresponding to the hot water circuit and the second flushing time corresponding to the ice water circuit are determined. When the first flushing time and the second flushing time are determined to overlap at least partially, the hot water circuit and the ice water circuit of the water purification equipment are connected to the same drainage circuit.

[0021] This invention analyzes water demand based on water intake instructions. If both hot and cold water are included, the flushing time for the hot water path and the cold water path are calculated separately. Then, it determines whether the two time periods overlap. If they overlap, the two water paths are controlled to share a single drainage loop to discharge the flushing wastewater. By merging the drainage, the need for separate drain outlets or pipes when discharging separately is avoided, simplifying the drainage structure design and reducing installation space requirements. At the same time, sharing the loop can reduce the number of solenoid valves or the complexity of synchronous control, avoid mutual interference when two paths drain simultaneously, thus improving the stability of the flushing process and the compactness of the system, without additionally extending the overall flushing time.

[0022] In one alternative implementation, the method further includes: During the flushing process of the water purification equipment, the total dissolved solids value of the water in the flushing pipeline of the water purification equipment is monitored; In response to the total dissolved solids value being less than the preset calibration value, the water purification equipment is controlled to stop the flushing action and start the water production action.

[0023] This invention monitors the total dissolved solids (TDS) value of the water in the flushing pipeline during the flushing process. When the TDS value is less than the preset calibration value, the flushing is stopped and the system switches to water production. By controlling the flushing endpoint with actual water quality indicators rather than a fixed duration, the system avoids insufficient or excessive flushing and ensures that each flush achieves the cleaning effect just right before switching to water production. This not only shortens unnecessary flushing delays and reduces water consumption, but also ensures that the output water quality is stable and meets the standards.

[0024] In a second aspect, the present invention provides a water purification equipment control device, the device comprising: The acquisition module is used to respond to the triggered water intake command, determine the target water output corresponding to the water intake command, and acquire the cumulative water intake within the preset water production cycle and the unwashed time from the last completion of the flushing action to the current time. The calculation module is used to calculate the water production demand based on the target water output and the cumulative water intake. The control module is used to determine the actions to be taken by the water purification equipment based on the water demand and the duration of non-rinsing, and to control the operation of the water purification equipment based on the actions taken.

[0025] Thirdly, the present invention provides a water purification device, the water purification device including a controller, the controller including: The memory and the processor are interconnected and communicate with each other. The memory stores computer instructions, and the processor executes the computer instructions to perform the method described in the first aspect or any of its corresponding embodiments.

[0026] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to perform the method described in the first aspect or any corresponding embodiment thereof. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] As an optional application scenario of this invention, such as Figure 1 The diagram shows a structural schematic of a water purification device. The water purification device includes a controller 101, which is used to execute a water purification device control method. The overall process of the controller 101 executing the water purification device control method is detailed in the relevant description of the method embodiment below, and will not be repeated hereafter.

[0033] The water purification device provided in this embodiment also includes an ice-making water circuit and a water-making water circuit, wherein the water-making water circuit can produce hot water or room temperature water. The water purification device in this embodiment can be a water purifier, which can be divided into a hot water or room temperature water circuit and an ice water circuit for water intake. The water purification device control method of this embodiment is adapted to process the water intake of the hot water circuit, room temperature water circuit, and ice water circuit, so as to reduce the rinsing waiting time in all water intake states.

[0034] With the improvement of living standards, consumers have increasingly stringent requirements for the quality and taste of drinking water, and the functions of household water purifiers are becoming more and more diverse. Water purifiers that integrate cooling, heating, filtration, and mineral additive functions, and can even make ice, are gaining popularity in the market. However, current water purification equipment suffers from the following significant technical challenges in the water purification process: Low water production efficiency and poor user experience: Traditional instant hot water purifiers (including products with cooling and ice-making functions, referred to as household ice makers below) typically require a pipeline flushing process before performing water production to remove impurities and stale water from the filter. Because the flushing process is performed sequentially (i.e., flushing first, then water production), when the pure water tank or ice water tank is low on water, users experience the double time cost of "waiting for flushing + waiting for water production," leading to prolonged refilling times for the pure water and ice water tanks and severely impacting the user's immediate drinking water experience.

[0035] Frequent pump start-stop cycles reduce lifespan: Current control logic typically triggers water production based on fixed cumulative water intake or simple time thresholds. This rigid triggering mechanism often leads to the control system frequently initiating the water production process when water demand is low or intervals are short. Each water production cycle is accompanied by a complete flushing-water production-flushing cycle, causing core components such as pumps and solenoid valves to start and stop frequently. This not only increases energy consumption but also accelerates mechanical wear and shortens equipment lifespan.

[0036] The conflict between water quality stability and hygiene: reducing rinsing frequency to increase speed may result in high TDS values ​​or poor taste in the initial output water; conversely, strictly ensuring rinsing before each water production cycle leads to water waste and inefficiency. Furthermore, for ice water systems, which rely on a purified water jug ​​for storage, untimely replenishment or stagnant water in the pipes can easily breed bacteria or affect water temperature stability.

[0037] This embodiment comprehensively analyzes multiple parameters of the water purification equipment, including "cumulative water intake and current water level," "time interval since last flush," and "current water temperature stability." The flushing logic is triggered only when a specific combination of conditions is met, thereby minimizing ineffective flushing while ensuring water quality. Further analysis of the different characteristics of the hot / room temperature water circuit and the chilled water circuit leads to the design of differentiated parallel control logic. Specifically for the chilled water circuit, the "chilled water / pure water replenishment" and "pipeline flushing" actions are overlapped on the time axis, achieving "flush while keeping ready" and eliminating sequential waiting time. Secondly, by analyzing historical water usage habits and equipment operating status, the "set water production threshold" and "estimated flushing time" are dynamically adjusted, making the control strategy more aligned with actual user scenarios and further enhancing the level of intelligence.

[0038] The water purification equipment control method provided in this embodiment aims to solve the problems of low water production efficiency and long user waiting time caused by the serial execution of flushing and water production processes in household water purification equipment, especially water purification equipment with ice-making function, such as ice makers; at the same time, it solves the problems of frequent pump start-stop, high energy consumption and short equipment life caused by fixed threshold triggering; and balances the contradiction between the need for pipeline hygienic flushing and the immediacy of water use.

[0039] According to an embodiment of the present invention, a method for controlling a water purification device is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0040] This embodiment provides a water purification equipment control method, which can be used in the aforementioned controller. Figure 2 This is a flowchart of a water purification equipment control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: In response to the triggered water intake command, determine the target water output corresponding to the water intake command and obtain the cumulative water intake within the preset water production cycle and the unrinsed time from the last completion of the rinsing action to the current time.

[0041] It should be noted that a water dispensing command is a signal issued by the user or system requesting the water purification device to provide drinking water. For example, a water dispensing command can be triggered by the user operating the buttons on the control panel of the water purification device, or by virtual buttons, sliding adjustments, or preset gestures on the touch screen of a water purification device with a touch panel.

[0042] The target water output is the expected single water intake volume corresponding to the water intake command.

[0043] The preset water production cycle is the time period from the completion of the previous water production cycle to the completion of the current water production cycle. The cumulative water intake within the preset water production cycle is the cumulative water intake from the completion of the current water production cycle to the completion of the next water production cycle. The cumulative water intake is the total amount of water taken out by all water intake operations within the current water production cycle.

[0044] The rinsing action is a water flow cleaning operation performed by the water purification equipment to remove impurities or residual water. The non-rinsing time is the time interval from the completion of the most recent rinsing action to the current time. These parameters are used together to determine whether rinsing needs to be performed before supplying water.

[0045] Step S202: Calculate the water production demand based on the target water output and cumulative water intake.

[0046] It should be noted that the target output volume is the volume of purified water expected to be obtained in this water intake command, the cumulative water intake volume is the total amount of water already taken out within the current preset water production cycle, and the water production demand is the total amount of water that the water production unit needs to cumulatively produce to meet all water intake needs within this cycle, including the cumulative amount already taken out and the target amount for this cycle. In actual products, the water production demand can be used to determine whether the water production unit has reached the cycle's water production capacity, and can serve as a basis for adjusting the water production time to ensure that the water tank reserve can cover the water that has been consumed and will be consumed soon. This ensures the freshness of the water while avoiding exceeding the cycle's rated water production capacity, which could lead to impurities clogging the filter element under high load.

[0047] Step S203: Based on the water production demand and the unrinsed time, determine the action to be performed by the water purification equipment, and control the operation of the water purification equipment based on the action.

[0048] It should be noted that the water production demand is the total amount of water required to replenish the sum of the water already taken in this cycle and the target output water volume at this time of water intake. The non-flushing time is the interval between the completion of the last flush and the current moment. The execution action is the specific operation taken by the water purification equipment based on a comprehensive judgment of these two parameters. This operation can include flushing, water production, or a combination of both. Operation control translates the determined flushing or water production action into actual on / off, speed, or opening adjustment commands for components such as water pumps, solenoid valves, and flushing valves, ensuring that the water purification equipment completes the water production and flushing actions according to preset timeframes, thereby ensuring the quality of the output water and the safety of system operation.

[0049] For example, the system assesses the current water production load and the duration of the unwashed period based on water demand and the time elapsed since the last wash to determine the appropriate action. For instance, if the demand is high and the unwashed period exceeds a threshold, wash before water production; if the demand is very low and the unwashed period is short, water can be produced directly or even without additional production. Following the determined action, specific operating commands are issued to components such as the water pump, wash valve, and pipeline switching valve, controlling start / stop times, speeds, and opening / closing sequences to complete the entire water intake process. By incorporating cumulative water intake and unwashed period data, the system can accurately determine whether washing is truly necessary, avoiding a fixed pattern of forced washing for every water intake. When the total water production within a cycle is low and the unwashed interval is short, washing can be skipped or significantly shortened, reducing water consumption and noise, and saving time waiting for washing to finish, allowing users to get water faster. Thorough cleaning is only performed during high-load water production or when the filter has not been washed for a long time, protecting the filter cartridge without excessively wasting time and resources. This ensures water quality safety while dynamically adjusting the flushing frequency and duration to maintain them at a reasonable lower limit, achieving on-demand flushing and efficient water output.

[0050] The water purification equipment control method provided in this embodiment adds the target water output to the accumulated water intake in the current cycle to obtain the water production demand, which represents the total water production required up to the current time in the current cycle. Furthermore, the water production demand and the unrinsed time are used as inputs to determine the action to be executed, and the water purification equipment is controlled based on this action. By including the accumulated water intake in the demand, the actual water production load of the filter cartridge can be comprehensively reflected. Combined with the unrinsed time, the rinsing decision no longer relies solely on a single time factor, but is dynamically linked to the current water production demand. This facilitates the determination of stages where rinsing is unnecessary or only a short-term rinsing is required, thereby effectively shortening the waiting time occupied by unnecessary rinsing while ensuring water quality, and improving water intake efficiency. It achieves the effect of adaptively reducing rinsing time according to actual operating conditions, reducing water and energy consumption while also shortening the waiting time before users obtain water, thus improving user satisfaction.

[0051] This embodiment provides a water purification equipment control method, which can be used in the aforementioned controller. Figure 3 This is a flowchart of a water purification equipment control method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps: Step S301: In response to the triggered water intake command, determine the target water output corresponding to the water intake command and obtain the cumulative water intake within the preset water production cycle and the unrinsed time from the last completion of the flushing action to the current time. For details, please refer to... Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0052] Step S302: Calculate the water production demand based on the target water output and cumulative water intake.

[0053] Specifically, step S302 includes: Step S3021: Calculate the sum of the target water output and the cumulative water intake to determine the water production demand.

[0054] It should be noted that by calculating the sum of the current water volume and the target water volume for this water intake, and comparing it with the water production threshold, feedback can be provided on whether water production is required for this water intake. If water production is required, flushing is performed, which improves the efficiency of water production. There is no need to wait for the actual water intake to reach the water production threshold before starting flushing and then producing water after flushing is completed.

[0055] The target water output is summed with the cumulative water intake to obtain the total water volume that needs to be produced in the current water production cycle.

[0056] The water purification equipment control method provided in this embodiment determines the flushing based on the total water production demand and the unflushing time, thereby proactively reducing flushing according to different situations. This effectively reduces the waiting time and water consumption of unnecessary flushing while ensuring water quality safety, and improves the water intake response speed.

[0057] Step S303: Based on the water production demand and the unrinsed time, determine the action to be performed by the water purification equipment, and control the operation of the water purification equipment based on the action.

[0058] Specifically, step S303 includes: Step S3031: Based on the relationship between the water demand and the preset water production threshold, and the relationship between the unrinsed time and the preset maximum allowable unrinsed time, determine the action to be performed by the water purification equipment.

[0059] It should be noted that the water production demand is the total amount of water that needs to be produced during this water intake cycle (i.e., the sum of the target output and the accumulated water intake); the preset water production threshold is a water production upper limit or judgment benchmark value set by the system to assess whether water production is currently needed.

[0060] Among them, the unrinsed time is the time interval from the completion of the last rinse to the start of the current rinse; the preset maximum allowable unrinsed time is the longest time that the system allows without rinsing, and exceeding this time is considered as requiring forced rinsing; the action to be executed is the operation instruction finally determined by the equipment based on the comparison and combination, such as starting rinsing, starting water production, pausing water output, or adjusting the flow rate.

[0061] The water purification equipment control method provided in this embodiment compares the water production demand with a threshold and the unflushing time with the maximum allowable time to comprehensively determine the action of the water purification equipment. This allows the equipment to make dynamic decisions based on the actual water production demand and the unflushing time, avoiding unnecessary waiting and waste caused by fixed-cycle flushing. When the water production demand is low and the intervals are short, the flushing frequency is reduced, saving water and electricity and shortening the time before water is drawn. At the same time, it reduces the risk of filter clogging, extends the maintenance cycle, and improves the overall user experience.

[0062] In some optional implementations, step S3031 above includes: Step a1: When it is determined that the water production demand is greater than or equal to the preset water production threshold and the unflushing time is less than the preset maximum allowable unflushing time, the water purification equipment is determined to perform a flushing action.

[0063] It should be noted that when the system determines that the total water volume to be produced has reached or exceeded the preset water production threshold, and the time since the last flush has not exceeded the maximum allowable interval, the equipment will automatically perform a flushing action instead of directly producing water or waiting for the timeout to occur. This aims to clean the filter cartridge promptly before high water production loads, preventing contaminants from accumulating on the filter surface for too long. This ensures both water production efficiency and water quality stability, while avoiding the longer waiting time or reduced flushing effect that might result from forced flushing after the timeout, thus balancing water quality assurance and water intake response speed.

[0064] Step a2: When it is determined that the water demand is less than the preset water production threshold and the unflushing time is greater than or equal to the preset maximum allowable unflushing time, the action to be performed by the water purification equipment is a flushing action.

[0065] It should be noted that in situations where water production demand is low but the unflushing time has exceeded the limit, the system will still determine that flushing is necessary even if the water production volume is small. This is to replace the concentrated water and any microorganisms that may have grown during the settling period. This effectively solves the decision-making blind spot of relying solely on the water production threshold. By initiating periodic cleaning, it effectively prevents scale buildup and bacterial growth on the filter surface caused by long-term inactivity, extending the overall lifespan of the filter and reasonably controlling the user's water dispensing waiting time.

[0066] Step a3: When it is determined that the water production demand is less than the preset water production threshold and the unflushing time is less than the preset maximum allowable unflushing time, or when it is determined that the water production demand is greater than or equal to the preset water production threshold and the unflushing time is greater than or equal to the preset maximum allowable unflushing time, the water purification equipment is determined to perform a water production action.

[0067] It should be noted that when the water demand is low and the time without flushing is short, and the equipment is in good condition, direct water production efficiency is the highest. When the water demand has reached a high load and the time without flushing has exceeded the limit, the system directly performs water production to meet the urgent water production needs. This can shorten the average water intake time by performing flushing while producing water, and can also prioritize ensuring the water output response speed, avoiding users from having no water available for a long time. At the same time, it reduces the loss of the water pump due to the extra idling of the water pump caused by pre-flushing, and improves the overall smoothness of equipment operation while ensuring basic water quality.

[0068] The water purification equipment control method provided in this embodiment determines the water production demand based on the sum of the target water output and the cumulative water intake; further, it determines the execution action based on the relationship between the water production demand and the preset water production threshold, and the relationship between the unflushing time and the preset maximum allowable unflushing time; and it controls the operation of the water purification equipment according to the execution action. By combining the water production demand and the unflushing time, flushing is only initiated when the demand has reached the threshold or the time has exceeded the limit, avoiding unnecessary flushing when both are low. This effectively reduces flushing time and water and electricity consumption, and ensures timely cleaning of the filter element and water safety when there is a high water production demand or the unflushing time is too long. At the same time, it further reduces the energy consumption of the water purification equipment caused by frequent start-stop of the equipment, reduces mechanical wear, extends the life of the water purification equipment, and improves the overall operating economy and water intake response speed of the water purification equipment.

[0069] In some alternative implementations, the method further includes: Step S304: Calculate the target water intake time based on the target water output.

[0070] It should be noted that the target water intake time is the continuous water output time required to produce the target water output. For example, the theoretically required time can be obtained by dividing the target water output by the water flow rate of the water purifier. This time can then be adjusted by combining pipeline water flow, start-stop delays, and other fine-tuning factors to ultimately control the precise shut-off timing of the water outlet valve or water pump, ensuring that the actual water output matches the target output.

[0071] Step S305: Calculate the flushing start time based on the preset single flushing time, the preset single water production time, and the target water intake time.

[0072] It should be noted that the preset single flushing time can be the duration required for a single complete flushing operation as set by the system, and the preset single water production time can be the time required to produce a fixed amount of water. The purpose of calculating the flushing start time is to reasonably arrange the start time of the flushing action in the entire water intake process, under the premise that the flushing action has been determined to be performed. For example, according to the order of flushing, water production, and water intake, flushing can be done first, followed by water production, and then water intake, to ensure that the actions are smoothly connected, the total time is minimized, and the timing of water output is not interfered with. This ensures that the flushing action starts exactly before water production or after water intake, avoiding unnecessary waiting.

[0073] Step S306: Based on the flushing start time, flushing control is performed on the water purification equipment.

[0074] It should be noted that the flushing control of the water purification equipment is based on the calculated flushing start time.

[0075] The water purification equipment control method provided in this embodiment calculates the target water intake time based on the target water output, and then calculates the flushing start time based on the preset single flushing time, preset single water production time, and target water intake time. Furthermore, it controls the operation of the water purification equipment based on the execution action. By comprehensively calculating the flushing start time with the time required for water production and water intake, the flushing action can be arranged in an appropriate window that is parallel to or precedes water production, avoiding the additional extension of the overall water intake process due to unreasonable flushing timing, thereby reducing user waiting time. At the same time, the three actions of flushing, water production, and water intake are closely linked, reducing equipment idling and repeated start-stop, and improving operational continuity and efficiency.

[0076] In some alternative implementations, the method further includes: Step S307: Obtain the water intake temperature set at the water intake level, and determine the water temperature difference between the outlet water temperature and the water intake temperature, wherein the outlet water temperature is the water temperature at the outlet of the water purifier.

[0077] The water dispensing levels are multiple preset temperature selection levels on the water purification equipment. Each level corresponds to a target water dispensing temperature value, such as 25°C, 45°C, 85°C, 100°C, etc. After the user selects a level, the system automatically uses the preset temperature associated with that level as the desired water temperature for this dispensing. Subsequent calculations of the water temperature difference and temperature control are all based on this set value.

[0078] The outlet water temperature refers to the temperature at the water outlet of the water purifier, which is the water outlet mentioned above. The outlet water temperature difference is intended to quantify the degree to which the current outlet water temperature deviates from the target temperature.

[0079] Step S308: When it is determined that the outlet water temperature difference is greater than or equal to the preset temperature difference value, the action to be performed by the water purification equipment is determined to be a rinsing action.

[0080] When the temperature difference reaches or exceeds the preset temperature difference value, it is determined that the current water temperature in the pipeline is significantly different from the target temperature, and the equipment performs a flushing action; this means that the interval between two water draws by the user is relatively long.

[0081] Step S309: When it is determined that the outlet water temperature difference is less than the preset temperature difference value, the action of the water purification equipment is determined to be water production action.

[0082] When the temperature difference does not reach the preset temperature difference value, it is determined that the difference between the current water temperature in the pipeline and the target temperature is small, and the equipment performs water production. This means that the interval between two water draws by the user is short, and the flushing action does not need to be performed.

[0083] The water purification equipment control method provided in this embodiment obtains the water intake temperature set at the water intake level and determines the water temperature difference between the outlet water temperature and the intake water temperature. When the outlet water temperature difference is greater than or equal to the preset temperature difference value, a flushing action is performed. When the outlet water temperature difference is less than the preset temperature difference value, a water production action is performed. By judging the temperature difference, it can be determined that when the outlet water temperature deviates significantly from the set value, the interval between two water intakes is long and the pipeline needs to be flushed first. When the temperature difference is small, it is determined that the interval between two water intakes is short and water can be produced directly, saving unnecessary flushing time and water waste. This ensures the temperature adjustment response speed, reduces water and energy consumption, and improves the overall comfort of temperature-controlled water intake.

[0084] The water purification equipment also includes an ice-making water circuit, and the above methods also include: Step b1: In response to the triggered ice-making water command, determine the target ice-making water volume corresponding to the ice-making water command and obtain the cumulative ice-making water volume within the preset ice-making water cycle.

[0085] It should be noted that an ice-making water command is a signal issued by the user or system requesting the water purification equipment to prepare purified water for ice making, which differs from ordinary water intake. The target ice-making water volume is the volume of purified water expected for ice making in the ice-making water command. The preset ice-making water cycle is a complete statistical cycle of ice-making water pre-set by the system; for example, the time period from the completion of the last ice making to the completion of the current ice making. The cumulative ice-making water volume is the total amount of purified water used for ice making within the current preset ice-making water cycle.

[0086] Step b2: Calculate the ice-making water demand based on the target ice-making water volume and the cumulative ice-making water volume.

[0087] The ice-making water requirement is obtained by summing the target ice-making water volume and the cumulative ice-making water volume.

[0088] Step b3: Control the water purification equipment to start discharging water. When it is determined that the demand for ice-making water is greater than the preset ice-making water threshold, perform a flushing action.

[0089] The preset ice-making water threshold is a threshold set by the system to determine the amount of ice-making water needed. If the calculated ice-making water demand exceeds the preset threshold, a rinsing action is performed during the water dispensing process, thereby shortening the user's waiting time for ice.

[0090] Alternatively, in step b4, in response to monitoring that the current water volume is less than a preset minimum water volume threshold during the water intake process, the water purification equipment is controlled to start replenishing water, and a flushing action is performed during the water replenishment process.

[0091] It should be noted that during the ice-making water extraction process, if the current water volume is detected to be lower than the preset minimum water volume threshold, the water purification equipment will start the water replenishment process, that is, purified water enters the ice-making water tank, and during the water replenishment operation, a flushing action is performed simultaneously to take advantage of the water flow renewal to clean the water flow, thereby reducing unnecessary waiting time for users while achieving the goal of flushing the water system.

[0092] For example, in the ice water circuit, the water source comes from the pure water jug ​​inside the water purifier. In this embodiment, a "replenishment-type" prediction is adopted. In response to the triggering of the ice water take command, the system monitors the water level of the pure water jug. When the system detects that the sum of the cumulative ice-making water volume and the target ice-making water volume is greater than or equal to the preset ice-making water volume threshold, it triggers the flushing and water replenishment commands of the pure water jug ​​to control the water purifier to perform the flushing and water replenishment actions.

[0093] That is: V total_ice +V req_ice ≥V threshold_ice , where V total_ice V represents the cumulative water volume used for ice making. req_ice V represents the target ice-making water volume. threshold_ice This indicates the preset ice-making water volume threshold.

[0094] In this embodiment, the pure water kettle is given the highest priority, and its rinsing process is embedded in the idle time during the ice water dispensing and replenishment process. For example, during the ice water dispensing process, once the conditions for replenishing ice water are met, the pure water kettle's water circuit is rinsed and replenished in advance. Then, after the ice water dispensing process ends, the ice water circuit can be turned on for replenishment, improving the efficiency of ice water replenishment and reducing the user's waiting time for refilling when the pure water kettle or ice water tank is low on water.

[0095] The water purification equipment control method provided in this embodiment determines the target ice-making water volume and obtains the cumulative ice-making water volume according to the ice-making water command, and calculates the ice-making water demand accordingly; controls the water purification equipment to start discharging water, and performs a flushing action when the demand exceeds the preset ice-making water volume threshold; at the same time, if the current water volume is detected to be less than the preset minimum water volume threshold during the water dispensing process, water replenishment is controlled, and flushing is performed during the water replenishment process; by triggering flushing through the demand threshold, flushing can be carried out in a timely manner when the ice-making water volume is high, ensuring the quality of the ice water; at the same time, the flushing is completed simultaneously with the water replenishment process when the water volume is insufficient, avoiding the separate occupation of extra flushing time, reducing user waiting time, and reducing the energy consumption of frequent water pump start-stop. Overall, it not only improves the safety of ice-making water, but also optimizes the timeliness of the flushing action.

[0096] The above methods also include: Step c1: Obtain the current water usage period.

[0097] The current water usage period refers to the time interval in which the water purification equipment determines the current moment based on its internal clock or usage records, and is used to distinguish the water usage patterns in different time periods.

[0098] Step c2: When it is determined that the current water usage period is during the peak water usage period, the preset water production threshold is lowered.

[0099] Peak water usage periods are determined based on users' water usage habits and are times when water consumption is high and water is frequently drawn. During these periods, the water purification equipment will automatically lower the preset water production threshold to store water in advance to meet the water demand during these periods.

[0100] Step c3: When it is determined that the current water usage period is in a low-peak water usage period, the preset water production threshold is increased, wherein the water consumption during the peak water usage period is greater than the water consumption during the low-peak water usage period.

[0101] Among them, the off-peak water usage period is the period of lower water consumption determined based on the user's water usage habits. The water purification equipment will increase the preset water production threshold, that is, raise the judgment benchmark, so that under the same demand, excessive water production or frequent flushing will occur during the period when the user does not frequently take water.

[0102] For example, in this embodiment, a machine learning algorithm can be introduced to achieve dynamic adjustment of the threshold, including: recording the user's peak water usage times and the distribution of single water usage. The system automatically adjusts the preset water production threshold V. threshold and preset maximum allowable unrinsing time T max For example, during the morning peak hours, the system tends to make more aggressive predictions (lowering the preset water production threshold V). threshold and preset maximum allowable unrinsing time T max (Initiate flushing earlier) to ensure a faster response time; and during low-frequency use periods at night, increase the preset water production threshold V. threshold and preset maximum allowable unrinsing time T max To reduce unnecessary pump start-up noise at night.

[0103] The water purification equipment control method provided in this embodiment obtains the current water usage period, lowers the preset water production threshold during peak water usage periods, and raises the preset water production threshold during off-peak water usage periods, wherein the water consumption during peak periods is greater than that during off-peak periods. By lowering the threshold during peak periods, the equipment can produce water and flush more actively in advance, ensuring the water supply and output speed during intensive water intake. By raising the threshold during off-peak periods, unnecessary water production and flushing frequency is reduced, saving water and electricity, reducing filter element wear and operating noise, realizing on-demand adjustment, and improving the overall operating economy and user experience.

[0104] Water purification equipment also includes hot water circuits and chilled water circuits, and the methods also include: Step d1: Determine the water demand based on the water demand command, and when the water demand includes hot water demand and ice water demand, determine the first flushing time corresponding to the hot water circuit and the second flushing time corresponding to the ice water circuit.

[0105] The water request instruction is a signal from the user requesting water supply. The water demand is the specific water usage type parsed from the instruction. Hot water demand and chilled water demand refer to the user's requests for hot water and chilled water, respectively. The hot water circuit is the piping within the water purification equipment used to transport and heat hot water, while the chilled water circuit corresponds to the piping used to cool and transport chilled water.

[0106] The first flushing time is the preset duration required to flush the hot water circuit, and the second flushing time is the flushing duration required for the ice water circuit.

[0107] Step d2: When it is determined that the first flushing time and the second flushing time at least partially overlap, control the hot water circuit and the ice water circuit of the water purification equipment to connect to the same drainage circuit.

[0108] The phrase "at least partially overlap between the first flushing time and the second flushing time" means that the flushing times of the two pipelines overlap on the time axis. For example, if the first flushing time is two minutes and the second flushing time is one minute, then the first flushing time and the second flushing time overlap by one minute.

[0109] The first flushing time and the second flushing time can also be completely coincident. Complete coincidence means that the flushing times of the two pipelines are equal on the time axis.

[0110] The "same drainage loop" refers to a shared pipe used by the water purification equipment for centralized discharge of flushing wastewater. When the first flushing time and the second flushing time overlap, the flushing wastewater from the two water lines is merged and introduced into the shared drainage channel to avoid drainage conflicts caused by separate discharges, which would increase the user's waiting time. By sharing a single drainage loop, the user's waiting time is reduced.

[0111] One method to connect the hot water and chilled water circuits of the water purification equipment to the same drainage circuit is by activating a dual-channel flushing solenoid valve. The first input of the dual-channel flushing solenoid valve is connected to the hot water circuit, the second input to the chilled water circuit, and the output to the drainage circuit. By controlling the solenoid valve to open, the two drainage streams are merged and discharged. Alternatively, a separate flushing solenoid valve can be installed on each of the hot water and chilled water circuits, and both valves can be opened simultaneously, causing the two flushing drainage streams to converge into the same drainage circuit.

[0112] For example, in this embodiment, a multi-waterway coordinated flushing strategy is implemented when there are two different waterways in the water purification device that need to be flushed; for example, it includes both hot water and ice water. When a user requests both hot and ice water simultaneously, the system can determine whether the flushing times of the two waterways overlap. If they overlap, the same drainage circuit is shared or the dual-flushing solenoid valves are activated synchronously, further shortening the overall system occupancy time and demonstrating a high degree of system integration intelligence.

[0113] The water purification equipment control method provided in this embodiment analyzes the water demand according to the water intake command. If both hot and cold water are included, the flushing time of the hot water circuit and the flushing time of the cold water circuit are calculated separately. Then, it is determined whether the two time periods overlap. If they overlap, the two water circuits are controlled to share a single drainage loop to discharge the flushing wastewater. By merging the drainage, the need to set up separate drain outlets or pipes when discharging separately is avoided, which simplifies the drainage structure design and reduces the installation space requirement. At the same time, sharing the loop can reduce the number of solenoid valves or the complexity of synchronous control, avoid mutual interference when the two circuits drain at the same time, and improve the stability of the flushing process.

[0114] The above methods also include: Step e1: During the flushing process of the water purification equipment, the total dissolved solids value of the water in the flushing pipeline of the water purification equipment is monitored.

[0115] The rinsing action refers to the process of cleaning the internal pipes and filter elements of the water purification equipment with high-speed water flow. The rinsing pipe is a specific pipe through which water flows during rinsing. The total dissolved solids (TDS) value is the value of the total dissolved solids content in the water, reflecting the ion concentration in the water. This value is monitored in real time during the rinsing process.

[0116] Step e2: In response to the total dissolved solids value being less than the preset calibration value, the water purification equipment is controlled to stop performing the flushing action and start performing the water production action.

[0117] The preset calibration value is the total dissolved solids (TDS) threshold set by the system. When the monitored value is lower than this value, it indicates that the flushing has fully replaced the concentrated water. The flushing is stopped and water production begins, which means the cleaning process ends and the system starts preparing clean water. The system automatically switches when the total dissolved solids (TDS) reaches the standard.

[0118] For example, a closed-loop flushing process based on online TDS monitoring is provided, which can be implemented by integrating a simple TDS sensor into the flushing pipeline. During the control process, the TDS value of the outflowing water is monitored when the flushing action is performed. If the detected TDS value is lower than the set standard, the flushing action is terminated in advance, and the water production action is initiated to enter the water production stage. This is more accurate than fixed time estimation and can flexibly adjust the flushing duration according to the actual fouling of the filter element, avoiding water waste caused by over-flushing.

[0119] The water purification equipment control method provided in this embodiment monitors the total dissolved solids value of the water in the flushing pipeline during the flushing process. When the value is less than the preset calibration value, the flushing is stopped and the system switches to water production. By controlling the flushing endpoint with actual water quality indicators rather than a fixed duration, insufficient or excessive flushing is avoided. This ensures that each flushing achieves the cleaning effect and immediately switches to water production, which shortens unnecessary flushing delays, reduces water consumption, and ensures that the output water quality is stable and meets the standards.

[0120] Combination Figure 4 and Figure 5 This describes one possible application embodiment of the water purification equipment control method. It can be applied to the dynamic predictive flushing control of the hot / room temperature water circuit in a hot and cold mineral water purifier.

[0121] The water purification system includes a main control module, flow sensor, temperature sensor, water pump, and solenoid valve assembly, etc. The control process includes the following: Step S1: The system monitors and records the cumulative water intake V in real time. total And the time interval T since the last rinsing action was completed. last Among them, T last This refers to the unrinsed time in the above method embodiments. Simultaneously, the heat exchanger outlet water temperature T in the current water circuit is monitored in real time. curr With the set target water temperature T set The deviation ΔT. Where, T set The water intake temperature set in the above method embodiments; T curr ΔT represents the outlet water temperature in the above method embodiment, and ΔT represents the outlet water temperature difference in the above method embodiment.

[0122] The cumulative water intake is the total water intake from the completion of this water production cycle to the completion of the next water production cycle.

[0123] Step S2: When the user selects the water dispensing level via the panel and sets the requested water volume to V, req When, i.e., V req To determine the target water output, the main control module executes predictive logic. First, it calculates the potential total water demand V. predict =Cumulative water intake V total +Target water output V req Secondly, obtain the system's preset water production threshold V. threshold (e.g., 300 mL) and the preset maximum permissible unrinsing time T max (For example, 2 hours). Next, assess the water temperature stability. If ΔT > δT, the water temperature is considered unstable and should be addressed first, or treated as a flushing signal. Here, δT represents the preset temperature difference, which can be between -5℃ and +5℃, for example, +5℃.

[0124] For example, if the current water outlet temperature is less than or equal to -5℃, it can be assumed that the interval between the user taking hot water is short, and therefore there is no need to perform a flush.

[0125] Step S3: Trigger Condition Determination. If the user clicks to retrieve water and one of the following conditions is met, a pre-flush is deemed necessary: ​​V predict ≥V threshold And T last <T max Although V predict <V threshold But T last ≥T max This indicates that there may be stagnant water in the pipeline, requiring forced flushing; ΔT>δT and the system is in standby mode. Among these, if only "V" predict ≥V threshold "or only "T" last <T max "At that time, there is no need to execute the logic of predictive flushing."

[0126] Step S4: Parallel timing scheduling. Once the above conditions are triggered, the main control module immediately calculates the estimated flushing time T. flush (e.g., 20 seconds), water production time T brew Water collection time T get Simultaneously, the flushing procedure is initiated. After flushing is complete, the water production procedure is immediately started. Because the flushing and subsequent water production processes completely or partially overlap with the user's water collection time, the perceived waiting time is only the difference between the completed flushing time and the actual waiting time (ideally close to zero). If T flush +T brew ≥T get If the user exits water extraction, the system and app will notify the user that water extraction is currently in progress. Compared to traditional solutions, parallel optimization has reduced some idling time.

[0127] Among them, the flushing time is the time for a single flush, which is a system setting; the water production time is the time for a single water production, which is a system setting; and the water collection time can be calculated in advance based on the target water collection volume to estimate how long it will take to collect water. By knowing the flushing time, water production time, and water collection time, it is possible to calculate how long after water collection is started that the flushing can be performed, minimizing the user's waiting time for water production.

[0128] For example, if a user draws a large amount of water, flushing and water production can be completed during the water draw.

[0129] In this embodiment, the water production process involves drawing tap water through a filtration system and then drawing the filtered pure water into a pure water jug ​​that provides the water source for the water dispensing function. This is the water production process.

[0130] This embodiment provides a water purification equipment control method that achieves a superior water consumption experience: Through dynamic prediction logic, when the system detects the need for new water preparation / replenishment, it predicts and initiates the pipeline flushing and new water preparation process regardless of whether the user is currently drawing water or not. By utilizing the overlap window between the estimated water consumption time and the preset flushing time, flushing waiting time is eliminated, significantly improving the level of intelligence and user experience. The system also optimizes the equipment operation logic and extends component lifespan: by introducing a multi-dimensional trigger judgment mechanism (cumulative water volume, time interval, water temperature stability, etc.), it avoids ineffective water production cycles triggered frequently with small water volumes. By merging flushing cycles or accurately predicting water production timing, unnecessary start-stop cycles of core components such as water pumps are reduced, lowering energy consumption and extending hardware lifespan. Furthermore, the system ensures water quality safety and energy and water conservation: by ensuring that the pipeline is clean in each actual water output, and that the newly prepared water volume is sufficient to cover current and future potential water consumption needs, it guarantees water hygiene and reduces unnecessary wastewater discharge through precise water replenishment control.

[0131] This embodiment also provides a water purification equipment control device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0132] This embodiment provides a water purification equipment control device, such as... Figure 6 As shown, it includes: The acquisition module 601 is used to respond to the triggered water intake command, determine the target water output corresponding to the water intake command, and acquire the cumulative water intake within the preset water production cycle and the unrinsed time from the last completion of the rinsing action to the current time.

[0139] In some alternative embodiments, the device further includes: The temperature acquisition module is used to acquire the water intake temperature set at the water intake level and determine the temperature difference between the outlet water temperature and the intake water temperature. The outlet water temperature is the water temperature at the outlet of the water purifier.

[0140] The flushing determination module is used to determine that the water purification equipment should perform a flushing action when the outlet water temperature difference is greater than or equal to a preset temperature difference value. The water production determination module is used to determine that the water purification equipment should perform a water production action when the temperature difference of the outlet water is less than the preset temperature difference value.

[0141] The water purification equipment also includes an ice-making water circuit, and the device also includes: The ice-making module is used to respond to the triggered ice-making water command, determine the target ice-making water volume corresponding to the ice-making water command, and obtain the cumulative ice-making water volume within the preset ice-making water cycle. The ice-making demand calculation module is used to calculate the ice-making water demand based on the target ice-making water volume and the cumulative ice-making water volume. The flushing module is used to control the water purification equipment to start discharging water. When it is determined that the demand for ice-making water is greater than the preset ice-making water threshold, the flushing action is performed. Alternatively, a water replenishment module is used to respond to the detection that the current water volume is less than a preset minimum water volume threshold during the water intake process, and to control the water purification equipment to start replenishing water. During the water replenishment process, a flushing action is performed.
