Description

Technical Field

[0001] This application relates to the field of mineral water preparation technology, and in particular to a control method, apparatus, mineral water purification equipment, computer-readable storage medium, and computer program product for a mineral water purification device. Background Technology

[0002] With increasing health awareness among residents, adequate amounts of minerals in drinking water are considered beneficial to human health. Therefore, water purification equipment with mineralization functions has gradually become one of the mainstream products in the market. Currently, the industry generally uses the method of adding mineral particles to the last stage filter of the water purifier to release beneficial mineral ions, such as strontium ions and zinc ions, into the water.

[0003] However, when the water purifier is in a static state, the water remains in contact with the mineral particles for an extended period, causing mineral ions to continuously dissolve. Studies have shown that after a certain period of standby time, the concentration of mineral ions in the water stored in the mineral filter increases significantly, potentially exceeding safe drinking water limits. Directly discharging this water, which exceeds the mineral ion concentration limits, to users poses a potential health risk. Summary of the Invention

[0004] Based on this, it is necessary to address the technical problem that the concentration of mineral ions in the water stored in the aforementioned mineralized filter cartridges increases significantly due to stagnation, posing a potential health risk when directly output to users. This necessitates providing a control method, device, mineralized water purification equipment, computer-readable storage medium, and computer program product for a mineralized water purification device.

[0005] In a first aspect, this application provides a control method for a mineralized water purification device, which is applied to a mineralized water purification device including a mineralized filter element, wherein the output side of the mineralized filter element is connected to a water storage container through a water replenishment branch.

[0006] The method includes:

[0007] Upon receiving a water intake command and determining that the water stored in the mineralized filter element needs to be diluted, the system acquires the water intake data, dilution water data, and water storage data of the water storage container corresponding to the water intake command.

[0009] If the expected water storage data meets the dilution water usage data, after water extraction is completed, the water replenishment branch is controlled to open to replenish water to the water storage container until the water storage container is determined to be full based on the water storage data of the water storage container, and then the water replenishment branch is controlled to close.

[0010] In one embodiment, the water storage container is connected to a water intake path, and a water pump is installed on the water intake path; the water storage data of the water storage container includes the current cumulative water intake time, and the water intake data corresponding to the water intake command includes the target water intake volume;

[0021] If the current total net water volume belongs to the second net water volume interval or the third net water volume interval, the second dilution water collection time is obtained as the dilution water collection time.

[0022] If the current total net water volume belongs to the fourth net water volume interval, the third dilution water collection time is obtained as the dilution water collection time.

[0023] The total net water volume in the first net water volume interval, the second net water volume interval, the fourth net water volume interval, and the third net water volume interval increases sequentially, and the water collection time for the first dilution, the water collection time for the second dilution, and the water collection time for the third dilution are water collection times that increase sequentially.

[0030] In one embodiment, the method further includes:

[0032] In one embodiment, the water storage volume corresponding to the water shortage state of the water storage container is greater than or equal to the volume of the mineralized filter element.

[0033] In one embodiment, determining that the water in the mineralized filter element needs to be diluted includes:

[0034] If the actual standby time of the mineralized water purification equipment is greater than or equal to the preset standby time, it is determined that the water stored in the mineralized filter element needs to be diluted.

[0035] or

[0036] If the mineral concentration of the water stored in the mineralized filter element is greater than or equal to the safe mineral concentration threshold, it is determined that the water stored in the mineralized filter element needs to be diluted.

[0037] Secondly, this application also provides a control device for a mineralized water purification equipment, which is applied to a mineralized water purification equipment including a mineralized filter element, wherein the output side of the mineralized filter element is connected to a water storage container through a water replenishment branch.

[0038] The device includes:

[0039] The data acquisition module is used to acquire water extraction data, dilution water data, and water storage data of the water storage container corresponding to the water extraction instruction when a water extraction instruction is received and it is determined that the water stored in the mineralized filter element needs to be diluted.

[0040] The state estimation module is used to estimate the water intake state based on the water storage data and the water intake data, and to determine the expected water storage data.

[0041] The water circuit control module is used to control the water replenishment branch to open after water extraction is completed, when the expected water storage data meets the dilution water data, to replenish water to the water storage container, until the water storage data of the water storage container determines that the water is full, and then control the water replenishment branch to close.

[0042] Thirdly, this application also provides a mineralized water purification device, including a mineralized filter element, wherein the output side of the mineralized filter element is connected to a water storage container through a water supply branch, and a water supply solenoid valve is provided on the water supply branch;

When the mineral concentration of the water stored in the mineralized filter cartridge exceeds the standard, the system obtains the data on the conditions required to effectively dilute the high-concentration mineralized water. Based on the water intake and storage data, it estimates whether the dilution conditions can be met, i.e., when the water storage container has enough space to accommodate the replenishment water for dilution after water intake, it controls the flow of the replenishment branch and uses freshly prepared low-concentration mineralized water to dilute the retained high-concentration mineralized water. This solves the technical problem that the mineral ion concentration of the water stored in the mineralized filter cartridge increases significantly due to stagnation, posing a potential health risk to the user if the water is directly output to the user.

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0062] The mineralized water purification equipment control method provided in this application embodiment can be applied to, for example... Figure 1 The illustrated mineralized water purification device includes a mineralized filter element 10. The output side of the mineralized filter element 10 is connected to a water storage container 20 via a water supply branch A, and a water supply solenoid valve 110 is installed on the water supply branch A. The mineralized water purification device also includes a controller 30, which is connected to the water supply solenoid valve 110 and controls the mineralized water purification device according to the control method provided in this application embodiment. A data storage system can store the data that the controller 30 needs to process. The data storage system can be integrated into the controller 30 or placed in the cloud or on other network servers.

[0063] Specifically, when the controller 30 receives a water intake command and determines that the water stored in the mineralization filter cartridge 10 needs to be diluted, it acquires the water intake data, dilution water data, and water storage data of the water storage container 20 corresponding to the water intake command; it estimates the water intake status based on the water storage data and the water intake data to determine the expected water storage data; when the expected water storage data meets the dilution water data, after the water intake is completed, it controls the water replenishment branch A to be turned on to replenish water to the water storage container 20 until it is determined that the water storage container 20 is full based on the water storage data of the water storage container 20, and then controls the water replenishment branch A to be turned off.

[0064] The controller 30 can be a control chip or control circuit board installed on the mineralized water purification equipment, or it can be an external control system based on wireless communication. The external control system can be implemented through devices such as terminals or servers. Terminals can be, but are not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection equipment, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0065] In one exemplary embodiment, such as Figure 2 As shown, a control method for a mineralized water purification device is provided, which is applied to... Figure 1 Taking controller 30 as an example, the explanation includes the following steps S202 to S206. Wherein:

[0066] Step S202: Upon receiving a water intake command and determining that the water stored in the mineralized filter cartridge needs to be diluted, obtain the water intake data, dilution water data, and water storage data of the storage container corresponding to the water intake command.

[0067] The water dispensing command refers to the trigger command initiated by the user through the mineralized water purification equipment or terminal to dispense purified water. Its source can be, but is not limited to: electrical signals generated by the user manually pressing or rotating the water dispensing switch, remote control commands received via the Internet of Things, or water dispensing commands automatically executed by the equipment according to a predetermined plan.

[0068] It is understood that a mineralizing filter cartridge refers to a filter element or filter media unit used in mineralizing water purification equipment to release mineral ions into the water. The water remaining inside the mineralizing filter cartridge refers to the mineralized water temporarily retained inside the cartridge and in the pipe near its outlet. When the equipment is in standby mode after water intake has ended, the water remaining inside the mineralizing filter cartridge will continue to come into contact with the mineral particles within the cartridge, potentially leading to an abnormally high concentration of mineral ions in the mineralized water. In this case, to ensure user safety, the high concentration of mineralized water remaining in the filter cartridge needs to be diluted to prevent this portion of water exceeding safe drinking water standards from being directly discharged to the user.

[0069] Specifically, upon receiving a water intake command, it is necessary to first determine whether the water remaining in the mineralized filter cartridge needs to be diluted. This involves assessing whether the mineral concentration of the currently retained mineralized water exceeds safe drinking water standards and whether it needs to be mixed with newly prepared mineralized water during this intake process to reduce the overall mineral concentration. If it is determined that the water remaining in the mineralized filter cartridge needs dilution, corresponding data such as the water intake data, dilution water data, and water storage data of the storage container must be obtained as the basis for determining how to proceed with the subsequent dilution action.

[0070] The water extraction data corresponding to the water extraction command refers to the set of parameters related to this water extraction behavior, which can be carried in the water extraction command. For example, the water extraction data includes at least parameters such as the user's requested target water extraction volume and target water temperature.

[0071] Dilution water data refers to the conditions that must be met to effectively dilute high-concentration mineralized water. This can refer to the amount of water required to dilute high-concentration mineralized water to below safe drinking water standards, or the time required to dilute it to below safe drinking water standards. This time can be the water intake time or the water production time.

[0072] A water storage container is a container inside a mineralized water purification device used to temporarily store prepared water for use. Common examples include pressure tanks or water tanks. The water storage data of a water storage container refers to parameters describing its current state. This can be the current water storage data, such as the current water volume, current available water usage time, or current water level; or it can be the cumulative water usage data, such as the current cumulative water usage volume or current cumulative water usage time.

[0073] For example, there is no single way to determine whether the water in the mineralized filter needs to be diluted. It can be based on a time threshold, a water quality threshold, a flow rate threshold, or, if a flushing mode is available, a flushing start command received.

[0074] In an exemplary embodiment, the determination in step S202 that the water in the mineralized filter cartridge needs to be diluted includes: determining that the water in the mineralized filter cartridge needs to be diluted when the actual standby time of the mineralized water purification device is greater than or equal to the preset standby time.

[0075] Specifically, the actual standby time refers to the total duration from the moment the mineralization water purification equipment completely finished its last water intake operation until a new water intake command is received. During this period, the equipment does not perform any operation to take water from the water intake port, and the mineralization filter element and its piping system are in a static, non-flowing state.

[0076] Furthermore, the preset standby time is the critical value required for the mineral concentration of the water stored in the mineralization filter cartridge to increase to exceed the safe drinking water standard under static conditions. If the actual standby time of the mineralization water purification equipment is greater than or equal to the preset standby time, it indicates that the mineral concentration of the water stored in the mineralization filter cartridge may have exceeded the safe drinking water standard, and it is determined that the water stored in the mineralization filter cartridge needs to be diluted. The value of the preset standby time is not fixed and can be set according to the actual situation of the mineralization filter cartridge. In one example of this application, the preset standby time can be set to 24 hours.

[0077] In an exemplary embodiment, the determination in step S202 that the water in the mineralized filter needs to be diluted includes: determining that the water in the mineralized filter needs to be diluted if the mineral concentration of the water in the mineralized filter is greater than or equal to a safe mineral concentration threshold.

[0078] Specifically, the mineral concentration of water stored in a mineralized filter cartridge refers to a quantitative indicator of the mineral content in the water, collected in real time or at regular intervals by a water quality monitoring device installed at the outlet of the mineralized filter cartridge (or at a specific location inside the filter cartridge). It can usually be characterized by total dissolved solids, conductivity, specific ion concentration, or a combination thereof.

[0079] Furthermore, the safe mineral concentration threshold is a preset concentration threshold, representing the highest safe limit for mineral concentration in the water flowing from the mineralization filter cartridge. If the mineral concentration of the water stored in the mineralization filter cartridge is greater than or equal to the safe mineral concentration threshold, it indicates that the mineral concentration of the water stored in the mineralization filter cartridge may have exceeded the safe drinking water standard, potentially posing an unpleasant taste or risk, and should not be consumed directly by the user. Therefore, the water stored in the mineralization filter cartridge needs to be diluted. The value of the safe mineral concentration threshold is not limited and can be set based on various criteria. For example, it can be set based on legal standard benchmarks, such as the limited values ​​for total dissolved solids (TDS) or specific ions (such as sodium and fluoride) in the national or industry-issued "Standards for Drinking Water Quality".

[0080] Step S204: Estimate the water intake status based on the water storage data and water intake data, and determine the expected water storage data.

[0081] Specifically, water intake status estimation refers to the predictive calculation made by the controller based on known data to estimate the state of the water storage container at a future point in time before or during the physical water intake action. The determined projected water storage data can characterize the expected water storage state in the container after the completion of this water intake action. Corresponding to the form of the water storage data, the projected water storage data can also be characterized using remaining water storage data or cumulative water intake data. Remaining water storage data can be characterized by parameters such as the projected remaining water volume, the projected remaining water intake time, and the projected water level. Cumulative water intake data can be characterized by parameters such as the projected cumulative water intake volume and the projected cumulative water intake time.

[0082] Furthermore, there is no single method for estimating water withdrawal status based on storage and withdrawal data; the method can be determined based on the different data representations of the storage and withdrawal data. For example, when storage data includes the current storage volume and withdrawal data includes the target withdrawal volume, estimating the water withdrawal status based on these two data points could involve directly calculating the difference between the current storage volume and the target withdrawal volume to obtain the estimated remaining storage volume as the estimated storage data. Another example is when storage data includes the current cumulative withdrawal time and withdrawal data includes the target withdrawal volume; one approach could be to first analyze the target withdrawal volume to obtain the target withdrawal time corresponding to the withdrawal action, and then use the sum of the current cumulative withdrawal time and the target withdrawal time to obtain the estimated cumulative withdrawal time as the estimated storage data.

[0083] Step S206: If the expected water storage data meets the dilution water usage data, after water intake is completed, control the water replenishment branch to open and replenish water to the water storage container until the water storage container is determined to be full based on the water storage data of the water storage container, and then control the water replenishment branch to close.

[0084] Specifically, the expected water storage data to meet the dilution water data means that after water is taken out, the water storage container has enough space to accommodate the replenishment water used for dilution, and after the replenishment is completed, the mineral concentration of the water in the storage container will not exceed the safe drinking water standard due to the high concentration of mineralized water flowing into the mineralization filter cartridge.

[0085] Furthermore, if the expected water storage data meets the dilution water usage data, after the water intake operation is completed, the water replenishment branch can be controlled to replenish the water storage container through the water flowing through the mineralization filter element. This replenishes the high-concentration mineralized water retained in the mineralization filter element into the water storage container, and continues to replenish the water storage container until it is full. Then, low-concentration freshly prepared mineralized water can be used to dilute the retained high-concentration mineralized water to ensure that the water in the final water storage container is within the safe drinking water standard.

[0086] Furthermore, during the process of replenishing water to the storage container, the water storage data of the container can be continuously monitored to determine whether the container is full. If it is determined that the container is full, the water replenishment branch is shut off, stopping the replenishment of water to the storage container. The water replenishment branch can be understood as the pipeline leading from the outlet of the mineralization filter to the storage container, which is typically equipped with a water replenishment solenoid valve. Correspondingly, controlling the opening and closing of the water replenishment branch can be achieved by controlling the on / off state of the water replenishment solenoid valve.

[0087] In one example, if the expected water storage data does not meet the dilution water usage data, the water replenishment action is not performed. After water extraction is completed, the process re-enters step S201, waiting to receive the next water extraction command before repeating the judgment. That is, after the next water extraction, the water storage container has enough space to accommodate the replenishment water used for dilution before initiating water replenishment.

[0088] For example, to ensure that the water storage container has sufficient space to accommodate the replenishment water used to dilute the high-concentration mineralized water inside the mineralization filter cartridge, the volume of the water storage container can be designed based on the volume of the mineralization filter cartridge. For instance, the volume of the water storage container can be designed to be a preset multiple of the volume of the mineralization filter cartridge. This preset multiple can be set based on the condition that the water stored in the final water storage container is within safe drinking water standards.

[0089] The aforementioned control method for mineralized water purification equipment, upon receiving a water intake command and determining that the water stored in the mineralized filter cartridge needs dilution, acquires the water intake data, dilution water data, and water storage data corresponding to the water intake command; estimates the water intake status based on the water storage data and the water intake data to determine the expected water storage data; if the expected water storage data meets the dilution water data, after water intake is completed, the water replenishment branch is opened to replenish water to the water storage container until the water storage container is determined to be full based on the water storage data, at which point the water replenishment branch is closed. When the mineral concentration of the water stored in the mineralized filter cartridge exceeds the standard, the method acquires the data on the conditions required for effectively diluting high-concentration mineralized water, and then estimates, based on the water intake data and the water storage data, that the dilution conditions can be met (i.e., the water storage container has sufficient space to accommodate the replenishment water for dilution after water intake), opens the water replenishment branch to use freshly prepared low-concentration mineralized water to dilute the retained high-concentration mineralized water. This solves the technical problem of a significant increase in mineral ion concentration in the water stored in the mineralized filter cartridge due to stagnation, which poses a potential health risk to the user if directly output to the user.

[0090] In one exemplary embodiment, such as Figure 3 As shown, the water storage container 20 is connected to a water intake passage B, and a water pump 8 is installed on the water intake passage B. Specifically, the water intake passage B refers to the water supply pipeline from the outlet of the water storage container 20 to the user's water intake. The water pump 8 is a pumping rate control device installed on the water intake passage B, which can be driven and controlled by a controller to actively pump water out of the water storage container 20 and transport it to the water intake.

[0091] For example, the water storage data of the water storage container includes the current cumulative water withdrawal time, and the water withdrawal data corresponding to the water withdrawal command includes the target water withdrawal volume. Figure 4 As shown, step S204 includes steps S302 to S304. Wherein:

[0092] Step S302: Calculate the target water intake time based on the target water intake volume and the pumping rate of the water pump.

[0093] Step S304: Based on the sum of the current cumulative water withdrawal time and the target water withdrawal time, obtain the estimated cumulative water withdrawal time, and use the estimated cumulative water withdrawal time as the estimated water storage data.

[0094] The current cumulative water extraction time is a cumulative time value, representing the total time the water pump has run in response to a received water extraction command since the last time the water storage container was replenished to full. It can be understood as the pump running time corresponding to the total amount of water extracted from the storage container, an indirect mapping of the current water storage state of the container in the time dimension. The target water extraction volume refers to the specific amount of purified water the user expects to obtain in this water extraction command. The pumping rate of the water pump refers to the constant flow rate of water extracted from the storage container per unit time under the control of the controller.

[0095] Specifically, the target water intake duration refers to the theoretically required operating time of the water pump to complete the target water intake volume corresponding to this water intake command. The target water intake duration can be obtained by the controller acquiring the pumping rate of the water pump based on the current control command for the water pump, and then dividing the target water intake volume by the pumping rate of the water pump to obtain the target water intake duration.

[0096] Furthermore, the estimated cumulative water extraction time is a predicted value, representing the total estimated cumulative operating time of the water pump since the last time the water storage container was filled to full, if this water extraction is completed. The estimated cumulative water extraction time can be directly obtained by summing the current cumulative water extraction time and the target water extraction time.

[0097] In this embodiment, some current mineralized water purification devices may not have devices in their storage containers to detect water level in real time. This embodiment converts the change in water volume into the operating time of the water pump. Since the pumping rate is known or measurable, the expected water extraction time directly corresponds to the total amount of water expected to be extracted from the storage container from when it is full until the current extraction is completed. Therefore, without relying on the addition of hardware sensors, the change in water volume in the storage container can be indirectly but accurately obtained using the system's inherent parameters, making the calculation simple and reliable.

[0098] In an exemplary embodiment, the dilution water data includes the dilution water intake duration; the expected water storage data in step S206 satisfies the dilution water data, including: the expected cumulative water intake duration is greater than or equal to the dilution water intake duration.

[0099] Specifically, to determine whether the projected water storage data meets the dilution water usage data, the expression of the dilution water usage data can be converted to be consistent with the projected water storage data, that is, the dilution water intake time can be used as the dilution water usage data. The dilution water intake time refers to the amount of water required to replenish the water stored in the mineralized filter cartridge, and the corresponding pump running time.

[0100] Correspondingly, the expected water storage data to meet the dilution water usage data can be expressed as: the expected cumulative water extraction time is greater than or equal to the dilution water extraction time. The logic of this comparison can be interpreted as follows: if, from the point of full water storage until the completion of this water extraction, the total operating time of the pump (i.e., the expected cumulative water extraction time) exceeds the operating time of the pump corresponding to the amount of water required for dilution (i.e., the dilution water extraction time), then it indicates that the water storage container has sufficient storage space to accommodate the dilution water. This allows for control of the water replenishment branch, using freshly prepared low-concentration mineralized water to dilute the retained high-concentration mineralized water.

[0101] In an exemplary embodiment, the step of obtaining the dilution water intake time includes: obtaining the dilution water intake time based on the current total water volume of the mineralized water purification equipment to which the water volume range belongs, the preset water volume range and the correspondence between the dilution water intake time.

[0102] like Figure 5 As shown, based on test results, the inventors discovered that after the same standby time, the mineral concentration of the high-concentration mineralized water retained by the mineralized filter cartridge and the total purified water volume exhibit a trend of first increasing and then decreasing with the total purified water volume. The reason for this is that in the initial stage of water flow, some pores inside the mineral particles are blocked by carbon powder / colloidal powder, resulting in low mineral dissolution. As water flow continues, the surface and internal pores of the mineral particles are gradually opened, increasing the surface area in contact with water and accelerating the mineral dissolution rate. Therefore, the mineral concentration of the high-concentration mineralized water retained by the mineralized filter cartridge increases after the same standby time. However, in the later stage of water flow, the effective components of the minerals are gradually consumed, reducing the amount of minerals dissolved.

[0103] Specifically, the current total purified water volume of a mineralized water purification system refers to the total amount of purified water successfully produced and output through the mineralized filter cartridge since the system was first put into use or the last time the mineralized filter cartridge was replaced. The current total purified water volume is a cumulative data point, which can be measured and accumulated by a flow meter installed in the internal water circuit, or estimated by the controller based on parameters such as water production time and rated water production rate. The purified water volume range to which the current total purified water volume belongs refers to several consecutive measurement segments pre-divided according to the performance degradation characteristics of the mineralized filter cartridge, defining the possible range of the current total purified water volume (e.g., from 0 liters to the rated total purified water volume of the filter cartridge).

[0104] Furthermore, the predefined correspondence between the purified water volume range and the dilution water collection time is a predefined mapping table or function relationship stored in the controller. It can clearly obtain the correspondence between each purified water volume range and a specific dilution water collection time. This correspondence can be designed based on the variation patterns found in the above research.

[0105] In one exemplary embodiment, the correspondence between the preset water purification volume range and the dilution water intake time is obtained based on the actual standby time of the mineralization water purification equipment.

[0106] Specifically, the correspondence used to query or calculate the dilution water extraction time does not need to be fixed. In this embodiment, it can be determined based on the actual standby time of the mineralization water purification equipment. It can be understood that even if the total purified water volume of the mineralization filter cartridge is within the same purified water volume range, if the standby time is particularly long, the mineral concentration of the water stored in the mineralization filter cartridge may be higher, thus requiring a stronger dilution action, i.e., a longer dilution water extraction time; conversely, if the standby time is very short, the dilution water extraction time can be appropriately reduced.

[0107] Furthermore, multiple different correspondences between purified water volume ranges and dilution water intake durations can be preset in the memory, each applicable to different actual standby times. In practical applications, the controller first obtains the actual standby time of the mineralization water purification equipment, then retrieves the corresponding correspondence between purified water volume ranges and dilution water intake durations from the memory based on the actual standby time. It then determines the purified water volume range to which the current total purified water volume of the mineralization water purification equipment belongs, and finally obtains the dilution water intake duration based on the retrieved correspondence.

[0108] In one exemplary embodiment, such as Figure 6 As shown, the dilution water intake time is obtained based on the correspondence between the current total purified water volume of the mineralized water purification equipment and the purified water volume range, the preset purified water volume range, and the dilution water intake time, including the following steps S402 to S406. Wherein:

[0109] Step S402: If the current total net water volume belongs to the first net water volume interval, obtain the first dilution water collection time as the dilution water collection time.

[0110] Step S404: If the current total net water volume belongs to the second net water volume interval or the third net water volume interval, obtain the second dilution water collection time as the dilution water collection time.

[0111] Step S406: When the current total net water volume belongs to the fourth net water volume interval, obtain the third dilution water collection time as the dilution water collection time; wherein, the total net water volume in the first net water volume interval, the second net water volume interval, the fourth net water volume interval and the third net water volume interval increase sequentially, and the first dilution water collection time, the second dilution water collection time and the third dilution water collection time are the water collection times that increase sequentially.

[0112] Specifically, the entire service life of the mineralized filter cartridge, from brand new to near its rated total water purification capacity, is divided into four consecutive range segments in ascending order of total water purification capacity: the first water purification capacity range, the second water purification capacity range, the fourth water purification capacity range, and the third water purification capacity range. For example, the first water purification capacity range is when the total water purification capacity W ≤ 1000L, the second water purification capacity range is when the total water purification capacity W is between 1000L and 2000L, the fourth water purification capacity range is when the total water purification capacity W is between 2000L and 5000L, and the third water purification capacity range is when the total water purification capacity W ≥ 5000L.

[0113] Furthermore, the dilution water intake time is set for the four consecutive range segments defined above. As the total net water volume of the mineralized filter cartridge increases (performance declines), the required dilution water intake time (manifested as a longer pump running time) increases accordingly to ensure the dilution effect. However, in the later stage of the entire usage cycle (corresponding to the range where the total net water volume is at its maximum), as the effective components of the mineral are gradually consumed and the amount of minerals dissolved decreases, a stronger dilution effect is not required, and the required dilution water intake time (manifested as a longer pump running time) decreases accordingly.

[0114] Correspondingly, a first dilution water intake time t1 is set for the first purified water volume range, a second dilution water intake time t2 is set for the second or third purified water volume range, and a third dilution water intake time t3 is set for the fourth purified water volume range, where t3>t2>t1>0.

[0115] For example, when the total purified water volume W ≤ 1000L, the mineral concentration of the water stored in the mineralized filter cartridge will be low after a certain standby time, possibly even lower than the safe drinking water standard. Therefore, the first dilution water dispensing time t1 can be set to 1s, meaning that as soon as the user dispenses water and the water level in the tank drops below the high level, the water replenishment action will be initiated. At this time, water replenishment will not cause the mineral ion concentration of the produced water to exceed the standard, and timely water replenishment can ensure a good continuous water dispensing experience for the user.

[0116] For example, when the total purified water volume W is between 1000L and 2000L, the mineral concentration of the water stored in the mineralization filter cartridge will increase after a certain standby time. More freshly prepared low-concentration mineralized water is needed to dilute the retained high-concentration mineralized water, i.e., the dilution water intake time needs to be increased. The second dilution water intake time t2 can be set to 6 seconds. When the cumulative working time of the water pump reaches 6 seconds, the water replenishment action is activated.

[0117] For example, when the total net water volume W is between 2000-5000L, the mineral concentration of the water in the mineralized filter cartridge is highest after a certain standby time. Therefore, it is necessary to further increase the dilution water intake time to use the largest amount of newly prepared low-concentration mineralized water to dilute the retained high-concentration mineralized water. The third dilution water intake time t3 can be set to 10s. When the cumulative working time of the water pump reaches 10s, the water replenishment action is activated.

[0118] For example, when the total net water volume W ≥ 5000L, the mineral concentration of the water stored in the mineralization filter cartridge will decrease after a certain standby time. This reduces the dilution water intake time, allowing less freshly prepared low-concentration mineralized water to dilute the retained high-concentration mineralized water. The second dilution water intake time t2 can be set to 6s. When the cumulative working time of the water pump reaches 6s, the water replenishment action is activated.

[0119] In one exemplary embodiment, such as Figure 7 As shown, the output side of the mineralization filter element 10 is also connected to a drainage branch C. Specifically, the drainage branch C refers to an independent pipeline branched off from the output side of the mineralization filter element 10, and its terminal is usually connected to the wastewater discharge port of the mineralization water purification equipment or a dedicated drainage chamber. A drainage solenoid valve controlled by the controller 30 is installed on the drainage branch C to control the opening and closing of the drainage branch C.

[0120] For example, the above-mentioned mineralized water purification equipment control method further includes: when it is determined that the water storage container has reached a water shortage state based on the expected water storage data, while starting water intake, controlling the drainage branch to be open until the preset drainage time is reached, controlling the drainage branch to be closed and controlling the water replenishment branch to be open.

[0121] The water storage container reaching a water shortage state means that the water level in the container is below a preset lower threshold. In this state, the water storage container cannot perform water intake operations, or it may affect the normal operation of the water pump.

[0122] Specifically, based on the projected water storage data, it is determined that the water storage container will reach a water shortage state after the completion of this water extraction operation. In this situation, the high-concentration mineralized water remaining in the mineralization filter cannot be resolved by dilution. If water is added to the storage container after water extraction is completed, it may lead to abnormal water extraction or even equipment malfunction. Therefore, it is necessary to drain the high-concentration mineralized water remaining in the mineralization filter through the drainage branch while starting water extraction to avoid direct output to the user.

[0123] Furthermore, if the water storage container is determined to be low on water based on the projected water storage data, the controller activates the water pump to draw water from the container for the user. Simultaneously, the solenoid valve of the drainage branch is activated. At this time, the high-concentration mineralized water retained in the mineralization filter element will not enter the water storage container but will be directly drained away through the drainage branch. The purpose of this operation is to quickly empty the high-concentration mineralized water retained in the mineralization filter element while water is being drawn, so that the water storage container can be replenished in a timely manner.

[0124] It is understandable that while controlling the solenoid valve of the drainage branch to open, the controller starts a timer to count the opening time of the solenoid valve. When the timer reaches the preset drainage duration, it is considered that the water in the filter element has been fully replenished, and the drainage branch is then shut off. At the same time as or very shortly after the drainage branch is shut off, the controller controls the water replenishment branch to open. At this time, freshly prepared mineralized water output from the mineralization filter element begins to be injected into the water storage container to replenish it. During this time, the controller can also continuously monitor the water storage data of the water storage container until it is determined that it has reached the full state, and then controls the water replenishment branch to shut off.

[0125] In this embodiment, by adding a drainage branch, the problem of ensuring water quality when conventional dilution and mixing cannot be carried out is solved. This satisfies the user's water intake needs while avoiding the potential health risks of directly outputting the high-concentration mineralized water retained in the mineralized filter cartridge to the user.

[0126] In one exemplary embodiment, continuing with reference to Figure 3 A low-level sensor 22 is installed at the lower limit of the water level in the water storage container 20. The water storage data of the water storage container includes low-level trigger data fed back by the low-level sensor 22. Specifically, the lower limit of the water level in the water storage container 20 represents the physical height position where the water level in the water storage container 20 has reached or fallen below the minimum requirement for safe operation. The low-level sensor 22 can be installed inside the water storage container 20 or at the lower limit of its connecting pipeline to detect whether there is water at the lower limit. When the liquid level drops below or equal to the lower limit, the detection state of the level sensor 22 changes, and low-level trigger data is fed back to the controller.

[0127] Correspondingly, the above-mentioned control method for mineralized water purification equipment also includes: when a water intake command is received but the water intake data corresponding to the water intake command is not obtained, when low liquid level trigger data is received, it is determined that the water storage container has reached a water shortage state, the drainage branch is controlled to be open, until the preset drainage time is reached, the drainage branch is controlled to be closed and the water replenishment branch is controlled to be open.

[0128] Specifically, "failed to obtain water intake data corresponding to the water intake command" means that the controller, when parsing the current water intake command, cannot determine a specific target water intake volume or target water intake duration. This could be due to the user triggering a water intake mode without a specific water volume setting, the water intake command originating from a non-standard interface resulting in incomplete or erroneous data transmission, or a malfunction or signal interference in the input device used to set the water intake volume.

[0129] In this situation, it is impossible to obtain the predicted water storage data, nor can it be predicted whether the water storage container will have enough space to accommodate the replenishment water used for dilution after water is drawn. Therefore, the replenishment and drainage branches can be temporarily left unattended, and the system can wait to see if a low liquid level trigger data is received during this water draw, i.e., whether the user will draw water at a low liquid level. If a low liquid level trigger data is received, it is determined that the water storage container has reached a water shortage state. The controller opens the drain solenoid valve of the drainage branch, starting to discharge the water stored in the mineralized filter cartridge. The controller starts a timer to time the drainage process. When the timer reaches the preset drainage duration, the controller shuts off the drainage branch. Simultaneously with shutting off the drainage branch, the controller activates the replenishment branch, starting to inject freshly prepared mineralized water into the water storage container.

[0130] It is understandable that if low liquid level trigger data is not received during this process, the process will re-enter step S201 and wait for the next water intake command to be received before repeating the judgment.

[0131] In an exemplary embodiment, the above-described mineralized water purification equipment control method further includes: outputting a rate adjustment command to a water pump in the water intake path connected to the water storage container, so as to control the pumping rate of the water pump to be less than or equal to the water production rate of the mineralized water purification equipment.

[0132] Specifically, the water production rate of a mineralization water purification equipment refers to the stable flow rate of qualified mineralized water that the internal water circuit of the equipment can produce per unit time under standard operating conditions. This can be understood as follows: when the water storage container is determined to be in a water shortage state, whether based on low liquid level trigger data or expected water storage data, a rate adjustment command must be output to the water pump connected to the water intake circuit of the storage container to control the pumping rate of the pump to be less than or equal to the water production rate of the mineralization water purification equipment.

[0133] This design ensures that even during continuous water extraction, the water level in the storage container drops as slowly as possible, and may even maintain a stable water level through replenishment via the water supply branch while water is being extracted. This prevents the storage container from being emptied in a time much shorter than required for a single extraction due to large water volumes, thus triggering the water shortage protection and interrupting water extraction. It also provides a more flexible time window for incorporating other control actions (such as drainage) during the water extraction process.

[0134] In one exemplary embodiment, the water storage volume corresponding to the water shortage state of the water storage container is greater than or equal to the volume of the mineralized filter element.

[0135] Specifically, the water storage volume corresponding to a water shortage state refers to the actual remaining water volume in the water storage container when it is determined that the container has entered a water shortage state. This value is directly or indirectly determined by the hardware or software threshold that triggers the water shortage determination. For example, if triggered by a low liquid level sensor, the volume is the internal volume of the container corresponding to the sensor's installation location. If triggered by software calculation based on the cumulative water extraction time, the volume is the difference between the total capacity of the water storage container and the water extraction amount corresponding to the maximum cumulative water extraction time.

[0136] It is understandable that the water storage volume corresponding to the water shortage state of the water storage container is greater than or equal to the volume of the mineralization filter element. This ensures that even in the extreme case where the water volume in the water storage container is at its lowest (i.e., water shortage state), the remaining water volume during the drainage of the mineralization filter element is sufficient for the user to use, and there will be no interruption of water supply.

[0137] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0138] In one exemplary embodiment, such as Figure 1 As shown, a mineralization water purification device is provided, including a mineralization filter element 10. The output side of the mineralization filter element 10 is connected to a water storage container 20 through a water supply branch A, and a water supply solenoid valve 110 is provided on the water supply branch A. The mineralization water purification device also includes a controller 30, which is connected to the water supply solenoid valve 110 and controls the mineralization water purification device according to the control method of the mineralization water purification device provided in the embodiments of this application.

[0139] Specifically, when the controller 30 receives a water intake command and determines that the water stored in the mineralization filter cartridge 10 needs to be diluted, it acquires the water intake data, dilution water data, and water storage data of the water storage container 20 corresponding to the water intake command; it estimates the water intake status based on the water storage data and the water intake data to determine the expected water storage data; when the expected water storage data meets the dilution water data, after the water intake is completed, it controls the water replenishment branch A to be turned on to replenish water to the water storage container 20 until it is determined that the water storage container 20 is full based on the water storage data of the water storage container 20, and then controls the water replenishment branch A to be turned off.

[0140] In one exemplary embodiment, such as Figure 7 As shown, the output side of the mineralization filter element 10 is also connected to a drainage branch C. A drainage solenoid valve 120 is installed on drainage branch C, and the drainage solenoid valve 120 is connected to the controller 30. Specifically, drainage branch C refers to an independent pipeline branched off from the output side of the mineralization filter element 10, and its terminal is typically connected to the wastewater discharge port of the mineralization water purification equipment or a dedicated drainage chamber. The drainage branch C is equipped with a drainage solenoid valve 120 controlled by the controller 30 to control the opening and closing of drainage branch C.

[0141] In one exemplary embodiment, such as Figure 8 As shown, the mineralization water purification equipment also includes a pressure-stabilizing pump 3 and a fine filter element 4, which are connected in series on the input side of the mineralization filter element 10; the other side of the drainage branch C is connected to the input side of the pressure-stabilizing pump 3. Specifically, by setting the end point of the drainage branch C on the input side of the pressure-stabilizing pump 3, the high-concentration mineralized water retained in the mineralization filter element can be reused after being filtered again by the fine filter element 4, thereby improving the water resource utilization rate.

[0142] In a specific embodiment, such as Figure 8 As shown, a mineralized water purification device is provided, including a pretreatment filter element 1, an inlet solenoid valve 2, a pressure stabilizing pump 3, a fine filter element 4, a wastewater solenoid valve 5, a first check valve 6, a second check valve 7, a water pump 8, a faucet 9, a mineralized filter element 10, a water replenishment solenoid valve 110, a drain solenoid valve 120, a flow detection element 130, and a water storage container 20.

[0143] The system includes a water inlet connected sequentially to a pretreatment filter cartridge 1, an inlet solenoid valve 2, a pressure stabilizing pump 3, a fine filter cartridge 4, a mineralization filter cartridge 10, a water replenishment solenoid valve 110, a first check valve 6, a water storage container 20, a water pump 8, and a faucet 9. This system purifies and mineralizes the raw water entering through the inlet, storing it in the water storage container 20 for user use. The pipeline between the mineralization filter cartridge 10 and the water storage container 20 is called the water replenishment branch A. The water replenishment solenoid valve 110 controls the opening and closing of the water replenishment branch A, and the first check valve 6 prevents backflow of water in the water storage container 20. Once the water pump 8 starts, it pumps water from the water storage container 20 to the faucet 9 for user use. The faucet 9 can be an electrically controlled faucet or a touch-sensitive faucet. The fine filter cartridge 4 also includes a wastewater path, with a wastewater solenoid valve 5 located on the wastewater path to control its opening and closing.

[0144] Furthermore, the output side of the mineralizing filter element 10 is connected to a drainage branch C, the end of which is located at the input side of the pressure-stabilizing pump 3. This allows the high-concentration mineralized water retained in the mineralizing filter element to be filtered again by the fine filter element 4 and reused, improving water resource utilization. A drainage solenoid valve 120 and a second check valve 7 are installed on the drainage branch C. The drainage solenoid valve 120 controls the opening and closing of the drainage branch C, and the second check valve 7 prevents water from the inlet from flowing back through the drainage branch C to the output side of the mineralizing filter element 10. A flow detection element 130 is located at the outlet of the mineralizing filter element 10 to detect the flow rate of the mineralized water.

[0145] Based on the same inventive concept, this application also provides a mineralized water purification equipment control device for implementing the above-mentioned mineralized water purification equipment control method. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more embodiments of the mineralized water purification equipment control device provided below can be found in the limitations of the mineralized water purification equipment control method described above, and will not be repeated here.

[0156] In an exemplary embodiment, the water circuit control module 103 is further configured to, when determining that the water storage container has reached a water shortage state based on the expected water storage data, start water intake while controlling the drainage branch to be open until the preset drainage time is reached, control the drainage branch to be closed and control the water replenishment branch to be open.

[0157] In an exemplary embodiment, the water circuit control module 103 is further configured to, when receiving a water intake command but not obtaining the water intake data corresponding to the water intake command, determine that the water storage container has reached a water shortage state when receiving low liquid level trigger data, control the drainage branch to be turned on, until the preset drainage time is reached, control the drainage branch to be turned off and control the water replenishment branch to be turned on.

[0158] In an exemplary embodiment, the water circuit control module 103 is further configured to output a rate adjustment command to the water pump of the water intake circuit connected to the water storage container, so as to control the pumping rate of the water pump to be less than or equal to the water production rate of the mineralized water purification equipment.

[0159] In an exemplary embodiment, the data acquisition module 101 is further configured to determine that the water stored in the mineralization filter cartridge needs to be diluted when the actual standby time of the mineralization water purification device is greater than or equal to the preset standby time.

[0160] In an exemplary embodiment, the data acquisition module 101 is further configured to determine that the water stored in the mineralized filter cartridge needs to be diluted if the mineral concentration of the water stored in the mineralized filter cartridge is greater than or equal to the safe mineral concentration threshold.
