Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water purification, and particularly relates to a water purification equipment control method, device, equipment and storage medium. BACKGROUND

[0002] With the rapid development of the water purification industry, reverse osmosis technology, as a mature water purification technology, is widely used in the filtration field of water purifiers. After water is prepared by a reverse osmosis membrane water purifier, the reverse osmosis membrane is soaked in tap water for a long time in the standby process. Since the total dissolved solids of the water on the raw water side of the reverse osmosis membrane are high, and the total dissolved solids of the pure water on the pure water side of the reverse osmosis membrane are low, under the action of osmotic pressure, the difference in the total dissolved solids on both sides of the membrane drives the salt in the water on the raw water side of the reverse osmosis membrane to permeate to the pure water side. After standing for a period of time, when the water purifier is restarted to prepare water, the total dissolved solids of the first cup of water will be relatively high, and the water quality is poor.

[0003] In the related art, a common method is to set a pure water backflow branch on the water outlet pipeline of the reverse osmosis device. Through the pure water branch, the pure water can flow back to before the booster pump, so as to achieve the purpose of replacing the pure water. The mixed pure water before the membrane of the reverse osmosis membrane filter element and the raw water in the pipeline can effectively reduce the total dissolved solids of the water on the raw water side. When standing again, the difference in the total dissolved solids on both sides of the membrane is reduced, the salt diffusion speed is slowed down, and the increase in the total dissolved solids of the water on the pure water side is reduced, so that the total dissolved solids of the first cup of water can be reduced, and the water quality of the first cup of water can be improved.

[0004] However, in the above method, the difference between the total dissolved solids of the raw water and the pure water is still large after backflow, which leads to a rapid increase in the total dissolved solids of the pure water, and the water quality of the water outlet of the water purifier is still not high.

In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0072] The water purification equipment control method provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0073] Referring to Figure 1 , Figure 1 A step flow chart of a water purification equipment control method provided by the embodiments of the present application is shown, which can specifically include the following steps:

[0074] Step 101, in the case that a pure water backflow pipeline of the water purification equipment is conducted, a first water quality value of raw water in a raw water storage space of the water purification equipment and a second water quality value of the raw water are acquired; wherein the acquisition time of the first water quality value and the second water quality value is different; the pure water backflow pipeline is used to drain pure water in a pure water storage space of the water purification equipment to the raw water storage space.

[0075] In embodiments of the present application, the water purification device can purify water and improve water quality, and the water purification device can include but is not limited to any one or a combination of a pre-filter, a central water purification machine, and a direct drinking machine. The water purification device can have a control center, such as a central processing unit (CPU) chip or a single-chip microcomputer. In this way, the water purification device can be controlled to perform various actions through the control center of the water purification device. The water purification device can include a filter element, such as a reverse osmosis membrane filter element, an adsorptive filter element, or other types of filter elements. In addition, the water purification device can also include a raw water storage space and a purified water storage space, the raw water storage space can store raw water that has not been filtered, and the raw water can be filtered by the filter element to obtain purified water, and the purified water can be stored in the purified water storage space. In embodiments of the present application, water quality can be evaluated using a water quality value. The water quality value can include total dissolved solids (TDS), non-dissolved solids, and other substance contents, and the unit is by default mg / L, indicating the mass of impurities contained in one liter of water. The higher the water quality value, the worse the water quality, and the lower the water quality value, the better the water quality. The water quality value of raw water is generally large, and the water quality value of purified water is generally small. In embodiments of the present application, when the purified water backflow pipeline is turned on, a water quality detector can be used to detect the water quality value of the raw water flowing into the raw water storage space at a certain frequency, so as to obtain a first water quality value of the raw water in the raw water storage space of the water purification device and a second water quality value of the raw water. The collection time nodes of the first water quality value and the second water quality value can be different, that is, if the first water quality value is obtained at the current time, the second water quality value of the raw water can be obtained at another time after a certain time length from the current time.

[0076] Step 102, determining a first difference between the first water quality value and the second water quality value.

[0077] In embodiments of the present application, after obtaining the first water quality value of the raw water and the second water quality value of the raw water, the difference between the first water quality value and the second water quality value can be calculated, and the absolute value of the difference can be taken as the first difference between the first water quality value and the second water quality value.

[0078] For example, if the first water quality value is 20 and the second water quality value is 21, the first difference between the first water quality value and the second water quality value is 1.

[0079] Step 103, in the case where the first difference is less than or equal to a first threshold value, closing the purified water backflow pipeline.

[0080] In the embodiments of the present application, a first threshold value can be set, the first difference value between the first water quality value and the second water quality value can be continuously acquired at a certain frequency, and the first difference value can be compared with the first threshold value. When the first difference value is greater than the first threshold value, the pure water backflow pipeline can be kept in the open state; when the first difference value is less than or equal to the first threshold value, it can be considered that the backflow is sufficient, and the pure water backflow pipeline has already introduced enough pure water into the raw water storage space, at this time, the pure water backflow pipeline can be closed by closing the switch valve on the pure water backflow pipeline, so that the introduction of pure water into the raw water storage space can be stopped.

[0081] In the above example, if the first threshold value is 3, since the first difference value is 1, which is less than the first threshold value, the pure water backflow pipeline can be immediately closed.

[0082] Step 104, in response to the water production instruction, a filtration program of the water purification device is executed to filter the raw water in the raw water storage space to the pure water storage space to obtain filtered pure water.

[0083] In the embodiments of the present application, the water production instruction can be triggered by a user through a button or other triggering device, or can be directly triggered by the control center of the water purification device. The water purification device can include a water production instruction triggering device for sending a water production instruction to the control center of the water purification device. The control center of the water purification device can receive the water production instruction and can execute the filtration program stored in the control center to start water production in response to the water production instruction, filter the raw water in the raw water storage space to the pure water storage space, so that the re-filtered pure water can be obtained.

[0084] In summary, the water purification device control method provided in the embodiments of the present application includes: acquiring a first water quality value and a second water quality value of raw water in a raw water storage space of a water purification device under the condition that a pure water backflow pipeline of the water purification device is open, wherein the acquisition time of the first water quality value and the second water quality value is different, the pure water backflow pipeline is used to introduce pure water in a pure water storage space of the water purification device to the raw water storage space, determining a first difference value between the first water quality value and the second water quality value, closing the pure water backflow pipeline under the condition that the first difference value is less than or equal to a first threshold value, and executing a filtration program of the water purification device in response to a water production instruction to filter the raw water in the raw water storage space to the pure water storage space to obtain filtered pure water. The water purification device control method can stop backflow when the raw water quality changes little, reduce the difference between the raw water quality value and the pure water quality value, reduce the rising speed of the pure water quality value, and improve the water quality of the water purification device.

[0085] Referring to Figure 2 , Figure 2 A step flowchart of another water purification device control method provided in the embodiments of the present application is shown, which can specifically include the following steps:

[0086] Step 201, in the case that a pure water return pipeline of a water purification device is conducted, a first water quality value of raw water in a raw water storage space of the water purification device and a second water quality value of the raw water are acquired; wherein, the first water quality value and the second water quality value are collected at different times; the pure water return pipeline is used for draining pure water in a pure water storage space of the water purification device to the raw water storage space.

[0087] In the embodiments of the present application, the implementation content of this step can refer to the embodiment content of step 101, which will not be repeated here.

[0088] As shown in the above examples, in the case that the first difference value is less than or equal to the first threshold value, the water inlet electromagnetic valve and the booster pump can be closed, so as to stop the pure water from being drained into the raw water storage space. Figure 3 Figure 3 is a partial internal structure schematic diagram of a water purification device provided by the embodiments of the present application. In the figure, the water purification device can include a reverse osmosis device, which is composed of a raw water storage space, a filtering device and a pure water storage space. There can be a water quality detector in the raw water storage space, which is used to detect the water quality of the raw water entering the raw water storage space. The pure water pipeline can connect the pure water storage space and the raw water branch, and communicate with the raw water storage space through the common pipeline. In addition, the raw water storage space can also be connected with a waste water branch, which can guide the raw water remaining in the raw water storage space after water production out of the water purification device. When producing water, the booster pump is opened, the water inlet electromagnetic valve located on the pure water return branch and the waste water electromagnetic valve located on the waste water branch are closed, so that the raw water can be introduced into the raw water storage space. After the water production is completed, the waste water electromagnetic valve is opened, and the waste water produced during the water production can be discharged out of the water purification device through the waste water branch. If the raw water branch does not enter water, the booster pump on the common pipeline and the water inlet electromagnetic valve on the pure water return pipeline are opened together, and the pure water in the pure water storage space can enter the raw water storage space through the pure water return pipeline and the common pipeline.

[0089] Step 202, determining a first difference value between the first water quality value and the second water quality value.

[0090] In the embodiments of the present application, the implementation content of this step can refer to the embodiment content of step 102, which will not be repeated here.

[0091] Step 203, in the case that the first difference value is less than or equal to a first threshold value, the pure water return pipeline is closed.

[0092] In the embodiments of the present application, the implementation content of this step can refer to the embodiment content of step 103, which will not be repeated here.

[0093] In the above examples, in the case that the first difference value is less than or equal to the first threshold value, the water inlet electromagnetic valve and the booster pump can be closed, so as to stop the pure water from being drained into the raw water storage space.

[0094] ​Step 204, acquire a third water quality value of the raw water in the raw water storage space when the pure water return pipeline is in a closed state.

[0095] In the embodiment of the present application, when the pure water return pipeline is closed, the third water quality value of the raw water can be acquired by the water quality detector in the raw water storage space. Other implementation contents of this step can refer to the embodiment contents of step 101, which will not be described here.

[0096] Step 205, determine a first standing time of the pure water in the pure water storage space of the water purification device based on the third water quality value.

[0097] In the embodiment of the present application, the water purification device can include a pure water return pipeline, which can communicate the raw water storage space and the pure water storage space. The pure water return pipeline can include a booster pump and a check valve. When the booster pump is turned on, the pure water return pipeline is conducted, so that the pure water in the pure water storage space can be drained to the raw water storage space. The check valve can prevent the raw water in the raw water storage space from flowing into the pure water storage space through the pure water return pipeline. There can be a pressure stabilizing pump on the raw water branch connected to the water inlet of the raw water storage device. When the pressure stabilizing pump is turned on, water is made, and when the pressure stabilizing pump is turned off, water making is stopped. In the embodiment of the present application, after the first water quality value of the raw water is acquired, the first standing time of the pure water in the pure water storage space of the water purification device can be determined according to the size of the third water quality value. The standing time can be the time length between the time when water making is stopped and the time when the pure water return pipeline is conducted, that is, the time length between the time when the pressure stabilizing pump of the raw water branch is turned off and the time when the booster pump of the pure water return pipeline is turned on. In the water purification device, due to the diffusion of ions and the difference in osmotic pressure between the raw water storage space and the pure water storage space, the water quality value of the pure water will gradually increase. When the water quality value of the raw water is larger, the diffusion speed of the ions is faster, and when the water quality value of the raw water is smaller, the diffusion speed of the ions is slower. Therefore, in the embodiment of the present application, a larger third water quality value can correspond to a smaller first standing time, and a smaller third water quality value can correspond to a larger first standing time.

[0098] Optionally, in step 205, the following sub-step can be included:

[0099] Sub-step 2051, when the third water quality value is greater than or equal to a second threshold value, determine that the first standing time is a first preset time length.

[0100] In the embodiments of this application, two raw water quality threshold values ​​can be set, namely a second threshold and a third threshold, wherein the second threshold can be greater than the third threshold. Thus, the raw water quality can be divided into three types based on the relationship between the third water quality value, the second threshold, and the third threshold. Furthermore, three preset settling times can be set, namely a first preset time, a second preset time, and a third preset time, wherein the first preset time can be less than the second preset time, and the second preset time can be less than the third preset time. According to the embodiment of step 205, a larger third water quality value corresponds to a smaller first settling time. Therefore, in the embodiments of this application, when the third water quality value is greater than or equal to the second threshold, the first preset time can be assigned to the first settling time, thereby determining the first settling time as the first preset time.

[0101] Sub-step 2052: If the third water quality value is less than the second threshold and greater than or equal to the third threshold, determine the first settling time as the second preset time; wherein the second preset time is greater than the first preset time.

[0102] In the embodiments of this application, when the third water quality value is less than the second threshold and greater than or equal to the third threshold, the raw water quality can be considered to be moderate. At this time, the second preset time can be assigned to the first settling time, thereby determining the first settling time as the second preset time. The second preset time can be greater than the first preset time.

[0103] Sub-step 2053: If the third water quality value is less than the third threshold, determine the first settling time as the third preset time; wherein the third preset time is greater than the second preset time.

[0104] In the embodiments of this application, when the third water quality value is less than the third threshold, the raw water quality can be considered to be good. According to the embodiment of step 205, a smaller third water quality value can correspond to a larger first settling time. At this time, the third preset time can be assigned to the first settling time, thereby determining the first settling time as the third preset time. The third preset time can be greater than the second preset time.

[0105] For example, the first preset duration can be set to 15 minutes, the second preset duration to 20 minutes, and the third preset duration to 30 minutes. The second threshold can be set to 500, and the third threshold can be set to 50. When the third water quality value is greater than or equal to 500, the first settling time can be set to 15 minutes; when the third water quality value is between 50 and 500, the first settling time can be set to 20 minutes; and when the third water quality value is less than 50, the first settling time can be set to 30 minutes.

[0106] In the embodiments of this application, when the third water quality value is greater than or equal to the second threshold, the first settling time is determined as the first preset time; when the third water quality value is less than the second threshold but greater than or equal to the third threshold, the first settling time is determined as the second preset time, wherein the second preset time is longer than the first preset time; when the third water quality value is less than the third threshold, the first settling time is determined as the third preset time, wherein the third preset time is longer than the second preset time. This allows for a hierarchical treatment of the settling time after water purification based on the raw water quality value. This can improve the output water quality of the water purification equipment when the raw water quality is poor, and further save energy while ensuring the output water quality when the raw water quality is good.

[0107] Step 206: When the settling time of the pure water reaches the first settling time, the pure water return pipeline of the water purification equipment is connected.

[0108] In the embodiments of this application, after the water purification equipment finishes producing water, the settling time of the pure water can be started. When the settling time of the pure water reaches the first settling time, it can be considered that the water quality value of the pure water has risen to a high level. At this time, the booster pump of the pure water return pipeline can be turned on to open the pure water return pipeline and divert the pure water in the pure water storage space to the raw water storage space.

[0109] For example, in Figure 3 In the internal structure of the water purifier shown, the pure water return pipeline can merge with the raw water branch and connect to the raw water storage space via a common branch. The pure water return pipeline can have an inlet solenoid valve and a check valve. When the pure water has been left to stand for a certain period of time, the inlet solenoid valve on the pure water return pipeline and the booster pump on the common pipeline can be opened, so that the pure water in the pure water storage space can flow into the raw water storage space through the pure water return pipeline and the common branch.

[0110] In the embodiments of this application, by obtaining the third water quality value of the raw water in the raw water storage space when the pure water return pipeline is in a closed state, the first settling time of the pure water in the pure water storage space of the water purification equipment is determined based on the third water quality value. When the pure water has reached the first settling time, the pure water return pipeline of the water purification equipment is opened. This can ensure the quality of the water output from the water purification equipment when the raw water quality is poor, and increase the settling time of the water purification equipment and reduce the frequency of opening the pure water return pipeline when the raw water quality is good. This can save energy while ensuring the quality of the water output from the water purification equipment when the raw water quality is good.

[0111] Step 207: Determine the first standby time of the water purification equipment based on the third water quality value.

[0112] In the embodiments of the present application, the standby time length of the water purification device can be the time length during which the pure water backflow pipeline maintains a closed state, that is, the time length between the previous closing time of the pure water backflow pipeline and the current opening time. After obtaining the third water quality value of the raw water, the first standby time length after the pure water backflow pipeline is closed can be determined according to the size of the third water quality value. A larger third water quality value can correspond to a smaller first standby time length, and a smaller third water quality value can correspond to a larger first standby time length.

[0113] For example, in the internal structure of the water purification device shown in Figure 3 In the internal structure of the water purification device shown in the figure, the standby time length of the water purification device can be the time length between the closing time of the water inlet electromagnetic valve and the next opening time of the water inlet electromagnetic valve.

[0114] Optionally, in step 207, the following sub-steps can be included:

[0115] Sub-step 2071: In the case where the third water quality value is greater than or equal to the second threshold value, the first standby time length is determined to be a fourth preset time length.

[0116] In the embodiments of the present application, the water quality of the raw water can be divided into three types according to the size relationship between the third water quality value of the raw water and the second threshold value and the third threshold value. In addition, three preset standby time lengths can be set, which are the fourth preset time length, the fifth preset time length and the sixth preset time length, wherein the fourth preset time length can be smaller than the fifth preset time length, and the fifth preset time length can be smaller than the sixth preset time length. According to the embodiment content of step 207, it can be known that a larger third water quality value can correspond to a smaller first standby time length, and therefore, in the embodiments of the present application, when the third water quality value is greater than or equal to the first threshold value, the fourth preset time length can be assigned to the first standby time length, so that the first standby time length can be determined to be the fourth preset time length.

[0117] Sub-step 2072: In the case where the third water quality value is less than the second threshold value and greater than or equal to the third threshold value, the first standby time length is determined to be a fifth preset time length; wherein the fifth preset time length is greater than the fourth preset time length.

[0118] In the embodiments of the present application, when the third water quality value is less than the second threshold value and greater than or equal to the third threshold value, it can be considered that the water quality of the raw water is moderate at this time, and at this time, the fifth preset time length can be assigned to the first standby time length, so that the first standby time length can be determined to be the fifth preset time length. The fifth preset time length can be greater than the fourth preset time length.

[0119] Sub-step 2073: In the case where the third water quality value is less than the third threshold value, the first standby time length is determined to be a sixth preset time length; wherein the sixth preset time length is greater than the fifth preset time length.

[0120] In the embodiments of this application, when the third water quality value is less than the third threshold, the raw water quality can be considered to be good. According to the embodiment of step 207, a smaller third water quality value can correspond to a larger first standby time. At this time, the sixth preset time can be assigned to the first standby time, thereby determining the first standby time as the sixth preset time. The sixth preset time can be greater than the fifth preset time.

[0121] For example, the fourth preset duration can be set to 10 minutes, the fifth preset duration to 16 minutes, and the sixth preset duration to 40 minutes. The second threshold can be set to 500, and the third threshold can be set to 50. When the third water quality value is greater than or equal to 500, the first standby duration can be set to 10 minutes; when the third water quality value is between 50 and 500, the first standby duration can be set to 16 minutes; and when the third water quality value is less than 50, the first standby duration can be set to 40 minutes.

[0122] In the embodiments of this application, when the third water quality value is greater than or equal to the second threshold, the first standby time is determined as the fourth preset time; when the third water quality value is less than the second threshold but greater than or equal to the third threshold, the first standby time is determined as the fifth preset time, wherein the fifth preset time is longer than the fourth preset time; when the third water quality value is less than the third threshold, the first standby time is determined as the sixth preset time, wherein the sixth preset time is longer than the fifth preset time. The standby time of the water purification equipment can be hierarchically processed according to the water quality value of the raw water. This can improve the output water quality of the water purification equipment when the raw water quality is poor, and further save energy while ensuring the output water quality of the water purification equipment when the raw water quality is good.

[0123] Step 208: When the standby time of the water purification equipment reaches the first standby time, the pure water return pipeline is connected.

[0124] In the embodiments of this application, the standby time of the water purification equipment can be started after the pure water return pipeline is closed. When the standby time of the water purification equipment reaches the first standby duration, the pure water return pipeline can be turned on again.

[0125] For example, in Figure 3 In the internal structure of the water purification equipment shown, the closing time of the inlet solenoid valve is the closing time of the pure water return pipeline. At this time, the standby time of the water purification equipment can be timed. When the standby time of the water purification equipment reaches the first standby time, the inlet solenoid valve and the booster pump can be turned on, thereby opening the pure water return pipeline.

[0126] In the embodiment of the present application, by determining the first standby duration of the water purification device based on the third water quality value, in the case that the standby time of the water purification device reaches the first standby duration, the pure water backflow pipeline is turned on, the standby duration of the water purification device can be determined according to the water quality value of the raw water, the water quality of the water purification device can be improved when the water quality of the raw water is poor, and the water quality of the water purification device can be ensured while saving electric energy when the water quality of the raw water is good.

[0127] Step 209, in response to the water making instruction, performing a filtration program of the water purification device to filter the raw water in the raw water storage space to the pure water storage space to obtain filtered pure water.

[0128] In the embodiment of the present application, the implementation content of this step can refer to the embodiment content of step 104, which will not be described here.

[0129] Optionally, in step 209, the following substep can be included:

[0130] Substep 2091, in the case that the water making instruction is received, determining the communication state of the pure water backflow pipeline; the communication state includes an on state and an off state.

[0131] In the embodiment of the present application, if the control center of the water purification device receives the water making instruction, the current communication state of the pure water backflow pipeline can be determined according to the on-off valve on the pure water backflow pipeline. The communication state includes an on state and an off state.

[0132] For example, as shown in the internal structure of the water purification device, Figure 3 If the water inlet electromagnetic valve is opened and the booster pump is opened, the pure water backflow pipeline is in the on state, and if the water inlet electromagnetic valve is closed, the pure water backflow pipeline is in the off state.

[0133] Substep 2092, in the case that the pure water backflow pipeline is in the on state, closing the pure water backflow pipeline.

[0134] In the embodiment of the present application, in the case that the water making instruction is received, if the pure water backflow pipeline is in the on state, the on-off valve on the pure water backflow pipeline can be closed to close the pure water backflow pipeline.

[0135] Substep 2093, in the case that the pure water backflow pipeline is in the off state, performing a filtration program of the water purification device in response to the water making instruction.

[0136] In the embodiment of the present application, in the case that the pure water backflow pipeline is in the off state, the filtration program of the water purification device can be performed in response to the water making instruction to start making water.

[0137] For example, as shown in the internal structure of the water purification device, Figure 3The water purification device shown in the internal structure, if the water inlet electromagnetic valve is closed, the booster pump can be opened alone to introduce raw water into the raw water storage space, and the raw water is filtered to the pure water storage space through the filtering device, so that water production can be carried out.

[0138] In the embodiment of the application, by determining the communication state of the pure water backflow pipeline in the case of receiving the water production instruction; the communication state includes the on state and the off state, in the case that the pure water backflow pipeline is in the on state, the pure water backflow pipeline is closed, and in the case that the pure water backflow pipeline is in the off state, the filtering program of the water purification device is executed in response to the water production instruction, the pure water backflow pipeline can be forcibly closed during water production, avoiding the pure water backflow to the raw water storage space during water production, and the water production efficiency of the water purification device is improved.
