Description

Technical Field

[0001] The present invention relates to the technical field of water treatment devices, and in particular to a water treatment device and a control method, device and readable storage medium thereof. Background Art

[0002] The key consumables in a water softener include softening salt. After the softening salt is added to the salt chamber, tap water is injected into the salt chamber to soak the softening salt particles to produce saturated brine. The saturated brine is then fully mixed with the softening resin to displace the calcium and magnesium ions absorbed in the softening resin, thereby enabling the softening resin to continuously maintain the calcium and magnesium ions in the softened water.

[0003] Among them, soft water salt is often prepared by natural dissolution method to obtain saturated brine. If the soft water salt is missing or the soft water salt is agglomerated at the bottom of the salt box, the natural dissolution of the soft water salt will be insufficient.

[0004] In the related technical solutions, the detection of saturated salt water concentration is not effectively achieved. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, a first aspect of the present invention provides a control method for a water treatment device.

[0007] A second aspect of the present invention provides a control device for a water treatment device.

[0008] A third aspect of the present invention provides another control device for a water treatment device.

[0009] A fourth aspect of the present invention provides a readable storage medium.

[0010] A fifth aspect of the present invention provides a water treatment device.

[0011] In view of this, a first aspect of the present invention provides a control method for a water treatment device, the water treatment device comprising a main body, a suspended part and a detection part, the main body having a cavity for accommodating a solution, the suspended part being immersed in the solution, the detection part being arranged opposite to the main body and being used to detect the height of the suspended part in the cavity, the control method for the water treatment device comprising: obtaining a detection result of the detection part; and determining the concentration of the solution according to the detection result.

[0012] The technical solution of the present application proposes a control method for a water treatment device, and the concentration of a solution can be monitored by running the control method.

[0013] Specifically, when the concentration of the solution is different, the density of the solution is also different, and correspondingly, the buoyancy of the suspended part is also different. When the density of the suspended part remains unchanged, its own gravity remains unchanged, and the position of the suspended part in the cavity will change under the action of the buoyancy and its own gravity in the solution.

[0014] Specifically, when the concentration of the solution is less than the density of the suspended part, the buoyancy of the suspended part is less than its own weight, and the gravity overcomes the buoyancy to drive the suspended part to move, thereby sinking downward. Conversely, when the concentration of the solution is greater than the density of the suspended part, the buoyancy of the suspended part is greater than its own weight, and the buoyancy overcomes the gravity to drive the suspended part to move, thereby floating upward. The buoyancy is related to the position of the suspended part in the solution. Based on this, the solution concentration of the suspended part at different positions can be pre-calibrated, and then the solution concentration can be detected through the position of the suspended part in the cavity.

[0015] By setting the detection element, the detection element can be used to detect the position information of the suspended element, thereby realizing the monitoring of the solution concentration.

[0016] In addition, the control method of the water treatment device proposed in this application also has the following additional technical features.

[0017] In the above technical solution, the detection result includes a magnetic field intensity value, and the concentration of the solution is determined according to the detection result, specifically including: determining a comparison result between the magnetic field intensity value and the magnetic field intensity interval; when the magnetic field intensity value is within the magnetic field intensity interval, determining the concentration of the solution according to the magnetic field intensity value; when the magnetic field intensity value is less than a lower limit value of the magnetic field intensity interval, the concentration of the solution is less than a first concentration; when the magnetic field intensity value is greater than an upper limit value of the magnetic field intensity interval, the concentration of the solution is greater than a second concentration; wherein the first concentration is less than the second concentration.

[0018] In this technical solution, the detection part detects the distance between the two by acquiring the magnetic field strength of the suspended part, and then detects the position information of the suspended part. The magnetic field strength value is compared with the magnetic field strength interval, and then the concentration of the solution is determined according to the judgment result of whether the magnetic field strength value is within the magnetic field strength interval. Specifically, when the magnetic field strength value is outside the magnetic field strength interval, the concentration of the solution is less than the first concentration or greater than the second concentration. In this process, the concentration corresponding to the above situation is selected to divide the corresponding magnetic field strength interval, so as to realize rapid determination of the solution concentration.

[0019] In any of the above technical solutions, when the magnetic field intensity value is within the magnetic field intensity range, the concentration of the solution is determined according to the magnetic field intensity value, specifically including: obtaining a first corresponding relationship between the magnetic field intensity value and the concentration value of the solution; and determining the concentration of the solution corresponding to the magnetic field intensity value according to the first corresponding relationship.

[0020] In this technical solution, the first corresponding relationship can be calibrated in advance, thereby ensuring the reliability of determining the concentration of the solution corresponding to the magnetic field intensity value according to the first corresponding relationship.

[0021] In any of the above technical solutions, it also includes: processing the detection result to obtain the height value of the suspended part in the cavity; determining the concentration of the solution according to the detection result, specifically including: determining the comparison result of the height value of the suspended part in the cavity and the height interval; when the height value of the suspended part in the cavity is within the height interval, determining the concentration of the solution according to the height value of the suspended part in the cavity; when the height value of the suspended part in the cavity is less than the lower limit value of the height interval, the concentration of the solution is less than the first concentration; when the height value of the suspended part in the cavity is greater than the upper limit value of the height interval, the concentration of the solution is greater than the second concentration; wherein the first concentration is less than the second concentration.

[0022] In this technical solution, the detection result is processed to obtain the height value of the suspended part in the cavity, so as to compare the height value of the suspended part in the cavity with the height interval, and then determine the concentration of the solution according to the judgment result of whether the height value of the suspended part in the cavity is located in the height interval. Specifically, when the height value of the suspended part in the cavity is outside the height interval, the concentration of the solution is less than the first concentration or greater than the second concentration. In this process, the concentration corresponding to the above situation is selected to divide the corresponding height interval, so as to realize the rapid determination of the solution concentration.

[0023] In any of the above technical solutions, when the height value of the suspended part in the cavity is within the height range, the concentration of the solution is determined according to the height value of the suspended part in the cavity, specifically including: obtaining a second corresponding relationship between the height value of the suspended part in the cavity and the concentration value of the solution; and determining the concentration of the solution corresponding to the height value of the suspended part in the cavity according to the second corresponding relationship.

[0024] In any of the above technical solutions, a connecting portion is provided on the main body for connecting the inside of the cavity with the outside of the cavity; the water treatment device also includes: a box and a pump, the box is used to contain the solution, the main body is arranged in the box, and the pump is used to extract the solution from the box; the control method also includes: when the detection result is consistent with the first detection result, determining the first slope of the curve obtained by fitting the detection result and time; when the first slope is in the first slope interval, controlling the pump to extract the solution.

[0025] In this technical solution, a connecting portion is provided on the main body so that the main body, the suspended part and the detection part constitute a detection device for being placed in a box, wherein the connecting portion on the main body is used to exchange the solution in the cavity with the solution in the box, thereby realizing the detection of the concentration of the solution in the box.

[0026] In the above technical solution, the first detection result may be a pre-calibrated detection result. For example, when the concentration of the pre-calibrated solution reaches the concentration required by the user, the detection result of the detection element is used as the first detection result.

[0027] In the above technical solution, when the test result is consistent with the first test result, it can be determined that the concentration of the solution has reached the concentration required by the user. The first slope is compared with the first slope interval so that the concentration of the measured solution can be verified using the comparison result. If the first slope is within the first slope interval, it is considered that the concentration change in the solution is within the expected range of change. At this time, the concentration measurement result of the solution is accurate and suitable for extracting the solution for use.

[0028] In the above embodiment, extraction conditions are set for the solution to ensure that the concentration of the extracted solution meets the concentration required by the user, thereby outputting a solution that meets the concentration requirements.

[0029] In the above technical solution, a curve fitting is performed between the test result and time to eliminate the data deviation that may exist in the test process using the test result, such as eliminating the mutation test result and reducing the influence of the mutation test result on the solution extraction. For example, if the mutation test result is too large, the probability of the extracted solution concentration being too low will occur.

[0030] In the above technical solution, the first slope may be the slope from the start of detection when the detection element is powered on until the detection result reaches the first detection result, or may be the slope from a certain detection result until the detection result reaches the first detection result.

[0031] Correspondingly, the first slope may be the slope from the time the detection element is powered on to the time the detection result reaches the first detection result, and the suspension element may be the rate of change of the suspension element height from floating up from the bottom wall of the cavity to the suspension height corresponding to the first detection result.

[0032] In any of the above technical solutions, it also includes: obtaining a first influencing parameter, the influencing parameter includes ambient temperature and / or the amount of solute; and determining a first slope interval according to the first influencing parameter.

[0033] In any of the above technical solutions, after controlling the pump to extract the solution, it also includes: obtaining the continuous operation time of the pump; when the continuous operation time is greater than the preset time, controlling the pump to stop running.

[0034] In this technical solution, the continuous running time of the pump can be used to control the pump so as to extract the solution, thereby meeting the usage requirements of different scenarios.

[0035] In any of the above technical solutions, after controlling the pump to extract the solution, it also includes: when the detection result is consistent with the second detection result, determining the second slope of the curve obtained by fitting the detection result and time; when the second slope is in the second slope range, controlling the pump to stop extracting the solution.

[0036] In this technical solution, by operating according to the above control logic, it is possible to automatically stop extracting the solution.

[0037] In this technical solution, in the process of extracting the solution by using a pump, the amount of solution in the box will gradually decrease. Therefore, the suspended part will gradually sink to the bottom wall of the cavity due to the decrease in the concentration of the solution. When the detection result is consistent with the second detection result, it is considered that the suspended part is detected to have sunk to the bottom wall of the cavity.

[0038] By determining the second slope of the curve obtained by fitting the detection result and time, and comparing the second slope with the second slope interval, the comparison result can be used to judge whether the solution extraction is abnormal. If the second slope is within the second slope interval, it is considered that the solution extraction is normal.

[0039] In the above embodiment, the comparison result between the second slope and the second slope interval can be used as a judgment condition for abnormal extraction, so that timely control can be performed in the case of abnormal extraction, thereby improving the stability of the water treatment device during operation.

[0040] In any of the above technical solutions, it also includes: obtaining a second influencing parameter, the influencing parameter includes a flow rate of the pump; and determining a second slope interval according to the second influencing parameter.

[0041] In any of the above technical solutions, the suspension element is a magnetic suspension element, and the detection element is a magnetic sensor.

[0043] The technical solution of the present application proposes a control device for a water treatment device, which can monitor the concentration of a solution.

[0044] Specifically, when the concentration of the solution is different, the density of the solution is also different, and the buoyancy of the suspended part is also different accordingly. When the density of the suspended part remains unchanged, its own gravity remains unchanged, and the position of the suspended part in the cavity will change under the buoyancy and its own gravity in the solution.

[0045] Specifically, when the concentration of the solution is less than the density of the suspended part, the buoyancy of the suspended part is less than its own weight, and the gravity overcomes the buoyancy to drive the suspended part to move, thereby sinking downward. Conversely, when the concentration of the solution is greater than the density of the suspended part, the buoyancy of the suspended part is greater than its own weight, and the buoyancy overcomes the gravity to drive the suspended part to move, thereby floating upward. The buoyancy is related to the position of the suspended part in the solution. Based on this, the solution concentration of the suspended part at different positions can be pre-calibrated, and then the solution concentration can be detected through the position of the suspended part in the cavity.

DETAILED DESCRIPTION

[0104] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0105] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0106] In one embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a control method for a water treatment device is proposed. The water treatment device includes a body 102, a suspension 108 and a detection member 110. The body 102 has a cavity 104 for containing a solution. The suspension 108 is immersed in the solution. The detection member 110 is arranged opposite to the body 102 and is used to detect the height of the suspension 108 in the cavity 104. The control method of the water treatment device includes:

[0107] Step 902, obtaining the test result of the test piece;

[0108] Step 904, determining the concentration of the solution according to the detection result.

[0109] The embodiment of the present application proposes a control method for a water treatment device, and the concentration of a solution can be monitored by running the control method.

[0110] Specifically, when the concentration of the solution is different, the density of the solution is also different, and correspondingly, the buoyancy of the suspended part is also different. When the density of the suspended part remains unchanged, its own gravity remains unchanged, and the position of the suspended part in the cavity 104 will change under the buoyancy and its own gravity in the solution.

[0111] Specifically, when the concentration of the solution is less than the density of the suspended component, the buoyancy of the suspended component is less than its own weight, and the gravity overcomes the buoyancy to drive the suspended component to move, thereby sinking downward. Conversely, when the concentration of the solution is greater than the density of the suspended component, the buoyancy of the suspended component is greater than its own weight, and the buoyancy overcomes the gravity to drive the suspended component to move, thereby floating upward. The buoyancy is related to the position of the suspended component 108 in the solution. Based on this, the solution concentration of the suspended component 108 at different positions can be pre-calibrated, and the solution concentration can be detected by the position of the suspended component 108 in the cavity 104.

[0112] By providing the detection member 110, the detection member 110 can be used to detect the height data of the suspended member, thereby realizing the monitoring of the solution concentration.

[0113] In one embodiment, the suspension member 108 can be understood as a float.

[0114] In one embodiment, the shape of the suspension member 108 may be spherical, cylindrical, cube or cuboid, which may be determined according to the shape of the cavity 104 and will not be described in detail herein.

[0115] In the above embodiment, the detection result includes a magnetic field strength value, and the concentration of the solution is determined according to the detection result, specifically including: determining a comparison result between the magnetic field strength value and the magnetic field strength interval; when the magnetic field strength value is within the magnetic field strength interval, determining the concentration of the solution according to the magnetic field strength value; when the magnetic field strength value is less than a lower limit value of the magnetic field strength interval, the concentration of the solution is less than a first concentration; when the magnetic field strength value is greater than an upper limit value of the magnetic field strength interval, the concentration of the solution is greater than a second concentration; wherein the first concentration is less than the second concentration.

[0116] In this embodiment, the detection component detects the distance between the two by acquiring the magnetic field strength of the suspended part, and then detects the position information of the suspended part. The magnetic field strength value is compared with the magnetic field strength interval, and then the concentration of the solution is determined according to the judgment result of whether the magnetic field strength value is within the magnetic field strength interval. Specifically, when the magnetic field strength value is outside the magnetic field strength interval, the concentration of the solution is less than the first concentration or greater than the second concentration. In this process, the concentration corresponding to the above situation is selected to divide the magnetic field strength interval corresponding to it, so as to realize rapid determination of the solution concentration.

[0117] The magnetic field strength value is used to represent the distance between the detection member 110 and the suspension member 108 , wherein the distance between the detection member 110 and the suspension member 108 is related to the height data of the suspension member 108 in the cavity 104 .

[0118] Specifically, since the detection member 110 and the main body 102 are arranged relative to each other, the position between the two is fixed. When the suspension member 108 floats up and down, the distance between the suspension member 108 and the detection member 110 will change, that is, the magnetic field strength value mentioned above will change. Therefore, the magnetic field strength value of the suspension member 108 at different heights in the cavity 104 can be pre-calibrated.

[0119] In any of the above embodiments, when the magnetic field strength value is within the magnetic field strength interval, determining the concentration of the solution according to the magnetic field strength value specifically includes: obtaining a first corresponding relationship between the magnetic field strength value and the concentration value of the solution; and determining the concentration of the solution corresponding to the magnetic field strength value according to the first corresponding relationship.

[0120] In this embodiment, the first corresponding relationship can be calibrated in advance to ensure the reliability of determining the concentration of the solution corresponding to the magnetic field intensity value according to the first corresponding relationship. In any of the above embodiments, it also includes: processing the detection result to obtain the height value of the suspended part in the cavity; determining the concentration of the solution according to the detection result, specifically including: determining the comparison result between the height value of the suspended part in the cavity and the height interval; when the height value of the suspended part in the cavity is within the height interval, determining the concentration of the solution according to the height value of the suspended part in the cavity; when the height value of the suspended part in the cavity is less than the lower limit of the height interval, the concentration of the solution is less than the first concentration; when the height value of the suspended part in the cavity is greater than the upper limit of the height interval, the concentration of the solution is greater than the second concentration; wherein the first concentration is less than the second concentration.

[0121] In this embodiment, the detection result is processed to obtain the height value of the suspended part in the cavity, so as to compare the height value of the suspended part in the cavity with the height interval, and then determine the concentration of the solution according to the judgment result of whether the height value of the suspended part in the cavity is located in the height interval. Specifically, when the height value of the suspended part in the cavity is outside the height interval, the concentration of the solution is less than the first concentration or greater than the second concentration. In this process, the concentration corresponding to the above situation is selected to divide the corresponding height interval, so as to realize the rapid determination of the solution concentration.

[0122] In any of the above embodiments, when the height value of the suspended part in the cavity is within the height range, determining the concentration of the solution according to the height value of the suspended part in the cavity specifically includes: obtaining a second corresponding relationship between the height value of the suspended part in the cavity and the concentration value of the solution; and determining the concentration of the solution corresponding to the height value of the suspended part in the cavity according to the second corresponding relationship.

[0123] In any of the above embodiments, a connecting portion 106 is provided on the main body 102 for connecting the interior of the cavity 104 with the exterior of the cavity 104; the water treatment device also includes: a box 202 and a pump 302, the box 202 is used to contain the solution, the main body 102 is arranged in the box 202, and the pump 302 is used to extract the solution from the box 202; the control method also includes: when the detection result is consistent with the first detection result, determining the first slope of the curve obtained by fitting the detection result and time; when the first slope is in the first slope interval, controlling the pump to extract the solution.

[0124] In this embodiment, a connecting portion 106 is provided on the main body 102 so that the main body 102, the suspension member and the detection member constitute a detection device for being placed in the box 202, wherein the connecting portion 106 on the main body 102 is used to exchange the solution in the cavity 104 with the solution in the box 202, thereby realizing the detection of the concentration of the solution in the box 202.

[0125] In the above embodiment, the first detection result may be a pre-calibrated detection result. For example, when the concentration of the pre-calibrated solution reaches the concentration required by the user, the detection result of the detection element 110 is used as the first detection result.

[0126] In the above embodiment, when the test result is consistent with the first test result, it can be determined that the concentration of the solution has reached the concentration required by the user, and the first slope is compared with the first slope interval so that the concentration of the measured solution can be verified using the comparison result. If the first slope is within the first slope interval, it is considered that the concentration change in the solution is within the expected range of change. At this time, the concentration measurement result of the solution is accurate and suitable for extracting the solution for use.

[0127] In the above embodiment, extraction conditions are set for the solution to ensure that the concentration of the extracted solution meets the concentration required by the user, thereby outputting a solution that meets the concentration requirements.

[0128] In the above embodiment, a curve fitting is performed between the test result and time to eliminate the data deviation that may exist in the test process using the test result, such as eliminating the sudden test result, and reducing the influence of the sudden test result on the solution extraction. For example, the probability of the situation that the concentration of the extracted solution is too low due to the sudden test result being too large is high.

[0129] In the above embodiment, the first slope may be the slope from the start of detection when the detection element is powered on until the detection result reaches the first detection result, or may be the slope from a certain detection result until the detection result reaches the first detection result.

[0130] Correspondingly, the first slope may be the slope from the time the detection element is powered on to the time the detection result reaches the first detection result, and the suspension element may be the rate of change of the suspension element height from floating up from the bottom wall of the cavity to the suspension height corresponding to the first detection result.

[0131] In any of the above embodiments, the method further includes: obtaining a first influencing parameter, the influencing parameter including ambient temperature and / or the amount of solute; and determining a first slope interval according to the first influencing parameter.

[0132] In this embodiment, the ambient temperature and / or the amount of solute are obtained so that the corresponding slope interval is selected as the first slope interval according to the selected ambient temperature and / or the amount of solute. During this process, the first slope interval can be dynamically changed according to the ambient temperature and / or the amount of solute, thereby ensuring the accuracy of the timing of solution extraction.

[0133] In one of the embodiments, the change process of solution concentration when a solute is dissolved in a solvent to form a solution at different ambient temperatures is pre-calibrated, and the change of the detection result of the suspended component is known based on the change process of the solution concentration, so as to obtain a reference slope of the first slope interval, and when the slope deviation is obtained, the first slope interval is calculated based on the reference slope and the slope deviation.

[0134] Specifically, the upper limit value of the first slope interval is obtained by adding the slope deviation to the reference slope, and the lower limit value of the first slope interval is obtained by subtracting the slope deviation from the reference slope.

[0135] Similarly, under different pre-calibrated amounts of solute, the concentration of the solution changes during the process of the solute dissolving in the solvent to form a solution, and based on the change in the concentration of the solution, the change in the detection result of the suspended part is known to obtain the reference slope of the first slope interval, and when the slope deviation is obtained, the first slope interval is calculated based on the reference slope and the slope deviation.

[0136] Specifically, the upper limit value of the first slope interval is obtained by adding the slope deviation to the reference slope, and the lower limit value of the first slope interval is obtained by subtracting the slope deviation from the reference slope.

[0137] In any of the above embodiments, after controlling the pump to extract the solution, the method further includes: obtaining the continuous operation time of the pump; and controlling the pump to stop running when the continuous operation time is greater than a preset time.

[0138] In this embodiment, the continuous operation time of the pump can be used to control the pump so as to extract the solution, thereby meeting the usage requirements of different scenarios.

[0139] In any of the above embodiments, after controlling the pump to extract the solution, it also includes: when the detection result is consistent with the second detection result, determining the second slope of the curve obtained by fitting the detection result and time; when the second slope is in the second slope range, controlling the pump to stop extracting the solution.

[0140] In this embodiment, by operating according to the above control logic, it is possible to automatically stop extracting the solution.

[0141] In this embodiment, in the process of extracting the solution by using the pump 302, the amount of the solution in the box 202 will gradually decrease. Therefore, the suspended part will gradually sink to the bottom wall of the cavity 104 due to the decrease in the concentration of the solution. When the detection result is consistent with the second detection result, it is considered that the suspended part is detected to sink to the bottom wall of the cavity.

[0142] By determining the second slope of the curve obtained by fitting the detection result and time, and comparing the second slope with the second slope interval, the comparison result can be used to judge whether the solution extraction is abnormal. If the second slope is within the second slope interval, the solution extraction is considered to be abnormal.

[0143] In the above embodiment, the comparison result between the second slope and the second slope interval can be used as a judgment condition for abnormal extraction, so that timely control can be performed in the case of abnormal extraction, thereby improving the stability of the water treatment device during operation.

[0144] In any of the above embodiments, the method further includes: obtaining a second influencing parameter, where the influencing parameter includes a flow rate of the pump 302; and determining a second slope interval according to the second influencing parameter.

[0145] In this embodiment, flow rate refers to the amount of fluid flowing through a closed pipe per unit time. In the embodiment of the present application, the flow rate of pump 302 refers to the amount of solution extracted by pump 302 per unit time. The greater the flow rate of pump 302, the greater the second slope.

[0146] Based on this, the pump 302 can be pre-calibrated to detect changes in the suspended component when extracting solution at different flow rates, so as to know the position change of the suspended component and obtain the reference slope of the second slope interval. When the slope deviation is obtained, the second slope interval can be calculated based on the reference slope and the slope deviation.

[0147] Specifically, the upper limit value of the second slope interval is obtained by adding the slope deviation to the reference slope, and the lower limit value of the second slope interval is obtained by subtracting the slope deviation from the reference slope.

[0148] In any of the above embodiments, the suspension element is a magnetic suspension element, and the detection element 110 is a magnetic sensor.

[0149] In this embodiment, the magnetic suspension part can be understood as a suspension part with magnetism. The magnetic field intensity sensor can detect the magnetic field radiated outward by the magnetic suspension part. The farther the magnetic sensor is from the magnetic suspension part, the smaller the magnetic intensity value is.

[0150] In one embodiment, the position information of the suspended component in the cavity 104 can be known according to the magnetic field strength detected by the magnetic field strength sensor, so as to detect the concentration of the solution to be detected.

[0151] In some embodiments of the present application, Fig.10 As shown, a control device 1000 for a water treatment device is provided. The water treatment device includes a main body 102, a suspended component 108 and a detection component 110. The main body 102 has a cavity 104 for accommodating a solution. The suspended component 108 is immersed in the solution. The detection component 110 is arranged opposite to the main body 102 and is used to detect the height of the suspended component 108 in the cavity 104. The control device 1000 for the water treatment device includes: an acquisition unit 1002, used to obtain a detection result of the detection component; and a detection unit 1004, used to determine the concentration of the solution according to the detection result.

[0152] The embodiment of the present application proposes a control device 1000 for a water treatment device, which can monitor the concentration of a solution.

[0153] Specifically, when the concentration of the solution is different, the density of the solution is also different, and correspondingly, the buoyancy of the suspended part is also different. When the density of the suspended part remains unchanged, its own gravity remains unchanged, and the position of the suspended part in the cavity 104 will change under the buoyancy and its own gravity in the solution.

[0154] Specifically, when the concentration of the solution is less than the density of the suspended part, the buoyancy of the suspended part is less than its own weight, and the gravity overcomes the buoyancy to drive the suspended part to move, thereby sinking downward. Conversely, when the concentration of the solution is greater than the density of the suspended part, the buoyancy of the suspended part is greater than its own weight, and the buoyancy overcomes the gravity to drive the suspended part to move, thereby floating upward. The buoyancy is related to the position of the suspended part 108 in the solution. Based on this, the solution concentration of the suspended part 108 at different positions can be pre-calibrated, and then the solution concentration can be detected through the position of the suspended part 108 in the cavity 104.

[0155] By providing the detection member 110, the detection member 110 can be used to detect the position information of the suspended member, thereby realizing the monitoring of the solution concentration.

[0156] In one embodiment, the suspension member 108 can be understood as a float.

[0157] In one embodiment, the shape of the suspension member 108 may be spherical, cylindrical, cube or cuboid, which may be determined according to the shape of the cavity 104 and will not be described in detail herein.

[0158] In one embodiment, the correspondence between different positions of the suspended component in the cavity 104 and the liquid concentration can be pre-calibrated, so that after obtaining the detection result of the suspended component in the cavity 104, the concentration of the solution can be determined based on the correspondence and the detection result.

[0159] In the above embodiment, the detection result includes a magnetic field intensity value, and the detection unit 1004 is specifically used to: determine a comparison result between the magnetic field intensity value and the magnetic field intensity interval; when the magnetic field intensity value is within the magnetic field intensity interval, determine the concentration of the solution according to the magnetic field intensity value; when the magnetic field intensity value is less than the lower limit of the magnetic field intensity interval, the concentration of the solution is less than the first concentration; when the magnetic field intensity value is greater than the upper limit of the magnetic field intensity interval, the concentration of the solution is greater than the second concentration; wherein the first concentration is less than the second concentration.

[0160] In this embodiment, the detection component detects the distance between the two by acquiring the magnetic field strength of the suspended part, and then detects the position information of the suspended part. The magnetic field strength value is compared with the magnetic field strength interval, and then the concentration of the solution is determined according to the judgment result of whether the magnetic field strength value is within the magnetic field strength interval. Specifically, when the magnetic field strength value is outside the magnetic field strength interval, the concentration of the solution is less than the first concentration or greater than the second concentration. In this process, the concentration corresponding to the above situation is selected to divide the magnetic field strength interval corresponding to it, so as to realize rapid determination of the solution concentration.

[0161] In any of the above embodiments, the detection unit 1004 is specifically used to: obtain a first corresponding relationship between a magnetic field intensity value and a solution concentration value; and determine the solution concentration corresponding to the magnetic field intensity value according to the first corresponding relationship.

[0162] In this embodiment, the first corresponding relationship may be calibrated in advance, thereby ensuring the reliability of determining the concentration of the solution corresponding to the magnetic field intensity value according to the first corresponding relationship.

[0163] In any of the above embodiments, the detection unit 1004 is specifically used to: process the detection result to obtain the height value of the suspended part in the cavity; determine the comparison result of the height value of the suspended part in the cavity and the height interval; when the height value of the suspended part in the cavity is within the height interval, determine the concentration of the solution according to the height value of the suspended part in the cavity; when the height value of the suspended part in the cavity is less than the lower limit value of the height interval, the concentration of the solution is less than the first concentration; when the height value of the suspended part in the cavity is greater than the upper limit value of the height interval, the concentration of the solution is greater than the second concentration; wherein the first concentration is less than the second concentration.

[0164] In this embodiment, the detection result is processed to obtain the height value of the suspended part in the cavity, so as to compare the height value of the suspended part in the cavity with the height interval, and then determine the concentration of the solution according to the judgment result of whether the height value of the suspended part in the cavity is located in the height interval. Specifically, when the height value of the suspended part in the cavity is outside the height interval, the concentration of the solution is less than the first concentration or greater than the second concentration. In this process, the concentration corresponding to the above situation is selected to divide the corresponding height interval, so as to realize the rapid determination of the solution concentration.

[0165] In any of the above embodiments, the detection unit 1004 is specifically used to: obtain a second corresponding relationship between the height value of the suspended component in the cavity and the concentration value of the solution; and determine the concentration of the solution corresponding to the height value of the suspended component in the cavity according to the second corresponding relationship.

[0166] In any of the above embodiments, a connecting portion 106 is provided on the main body 102 for connecting the interior of the cavity 104 with the exterior of the cavity 104; the water treatment device also includes: a box 202 and a pump 302, the box 202 is used to contain the solution, the main body 102 is arranged in the box 202, and the pump 302 is used to extract the solution from the box 202; the detection unit 1004 is also used to: when the detection result is consistent with the first detection result, determine the first slope of the curve obtained by fitting the detection result and time; when the first slope is in the first slope interval, control the pump to extract the solution.

[0167] In this embodiment, a connecting portion 106 is provided on the main body 102 so that the main body 102, the suspension member and the detection member constitute a detection device for being placed in the box 202, wherein the connecting portion 106 on the main body 102 is used to exchange the solution in the cavity 104 with the solution in the box 202, thereby realizing the detection of the concentration of the solution in the box 202.

[0168] In the above embodiment, the first detection result may be a pre-calibrated detection result. For example, when the concentration of the pre-calibrated solution reaches the concentration required by the user, the detection result of the detection element is used as the first detection result. In the above embodiment, when the detection result is consistent with the first detection result, it can be determined that the concentration of the solution has reached the concentration required by the user. By comparing the first slope with the first slope interval, the concentration of the measured solution can be verified by using the comparison result. If the first slope is within the first slope interval, it is considered that the concentration change in the solution is within the expected change range. At this time, the concentration measurement result of the solution is accurate and suitable for extracting the solution for use.

[0169] In the above embodiment, extraction conditions are set for the solution to ensure that the concentration of the extracted solution reaches the concentration required by the user, thereby outputting a solution that meets the concentration requirements.

[0170] In the above embodiment, a curve fitting is performed between the test result and time to eliminate the data deviation that may exist in the test process using the test result, such as eliminating the sudden test result, and reducing the influence of the sudden test result on the solution extraction. For example, the probability of the situation that the concentration of the extracted solution is too low due to the sudden test result being too large is high.

[0171] In the above embodiment, the first slope may be the slope from the start of detection when the detection element is powered on until the detection result reaches the first detection result, or may be the slope from a certain detection result until the detection result reaches the first detection result.

[0172] Correspondingly, the first slope may be the slope from the time the detection element is powered on to the time the detection result reaches the first detection result, and the suspension element may be the rate of change of the suspension element height from floating up from the bottom wall of the cavity to the suspension height corresponding to the first detection result.

[0173] In any of the above embodiments, the detection unit 1004 is further used to: obtain a first influencing parameter, where the influencing parameter includes the ambient temperature and / or the amount of the solute; and determine a first slope interval according to the first influencing parameter.

[0174] In this embodiment, the ambient temperature and / or the amount of solute are obtained so that the corresponding slope interval is selected as the first slope interval according to the selected ambient temperature and / or the amount of solute. During this process, the first slope interval can be dynamically changed according to the ambient temperature and / or the amount of solute, thereby ensuring the accuracy of the timing of solution extraction.

[0175] In one of the embodiments, the change process of solution concentration when a solute is dissolved in a solvent to form a solution at different ambient temperatures is pre-calibrated, and the change of the detection result of the suspended component is known based on the change process of the solution concentration, so as to obtain a reference slope of the first slope interval, and when the slope deviation is obtained, the first slope interval is calculated based on the reference slope and the slope deviation.

[0176] Specifically, the upper limit value of the first slope interval is obtained by adding the slope deviation to the reference slope, and the lower limit value of the first slope interval is obtained by subtracting the slope deviation from the reference slope.

[0177] Similarly, under different pre-calibrated amounts of solute, the concentration of the solution changes during the process of the solute dissolving in the solvent to form a solution, and based on the change in the concentration of the solution, the change in the detection result of the suspended part is known to obtain the reference slope of the first slope interval, and when the slope deviation is obtained, the first slope interval is calculated based on the reference slope and the slope deviation.

[0178] Specifically, the upper limit value of the first slope interval is obtained by adding the slope deviation to the reference slope, and the lower limit value of the first slope interval is obtained by subtracting the slope deviation from the reference slope.

[0179] In any of the above embodiments, after the pump is controlled to extract the solution, the detection unit 1004 is further used to: obtain the continuous operation time of the pump; when the continuous operation time is greater than a preset time, control the pump to stop running.

[0180] In this embodiment, the continuous operation time of the pump can be used to control the pump so as to extract the solution, thereby meeting the usage requirements of different scenarios.

[0181] In any of the above embodiments, after the control pump extracts the solution, the detection unit 1004 is also used to: when the detection result is consistent with the second detection result, determine the second slope of the curve obtained by fitting the detection result and time; when the second slope is in the second slope interval, control the pump to stop extracting the solution.

[0182] In this embodiment, by operating according to the above control logic, it is possible to automatically stop extracting the solution.

[0183] In this embodiment, in the process of extracting the solution by using the pump 302, the amount of the solution in the box 202 will gradually decrease. Therefore, the suspended part will gradually sink to the bottom wall of the cavity 104 due to the decrease in the concentration of the solution. When the detection result is consistent with the second detection result, it is considered that the suspended part is detected to sink to the bottom wall of the cavity.

[0184] By determining the second slope of the curve obtained by fitting the detection result and time, and comparing the second slope with the second slope interval, the comparison result can be used to judge whether the solution extraction is abnormal. If the second slope is within the second slope interval, it is considered that the solution extraction is normal.

[0185] In the above embodiments, the comparison result between the second slope and the second slope interval can be used as a judgment condition for abnormal extraction, which can realize timely control in the case of abnormal extraction, thereby improving the stability of the water treatment device during operation. In any of the above embodiments, the detection unit 1004 is also used to: obtain a second influencing parameter, the influencing parameter including the flow rate of the pump; and determine the second slope interval according to the second influencing parameter.

[0186] In this embodiment, flow rate refers to the amount of fluid flowing through a closed pipe per unit time. In the embodiment of the present application, the flow rate of pump 302 refers to the amount of solution extracted by pump 302 per unit time. The greater the flow rate of pump 302, the greater the second slope.

[0187] Based on this, the pump 302 can be pre-calibrated to detect changes in the suspended component when extracting solution at different flow rates, so as to know the position change of the suspended component and obtain the reference slope of the second slope interval.

[0189] In any of the above embodiments, the suspension element is a magnetic suspension element, and the detection element 110 is a magnetic sensor.

[0190] In some embodiments of the present application, Fig.11 As shown, a control device 1100 for a water treatment device is provided, comprising: a controller 1102 and a memory 1104, wherein the memory 1104 stores a program or instruction, and the controller 1102 implements the steps of any of the above-mentioned control methods for a water treatment device when executing the program or instruction in the memory 1104.

[0191] In some embodiments of the present application, a readable storage medium is provided, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the control method of the water treatment device as in any of the above embodiments are implemented.

[0192] In some embodiments of the present application, a water treatment device is provided, including: a main body 102, the main body 102 having a cavity 104 for containing a solution; a suspended member 108, immersed in the solution; a detection member 110, the detection member 110 is arranged opposite to the main body 102; a control device such as any of the above-mentioned water treatment devices; and / or a readable storage medium such as the above-mentioned.

[0193] The water treatment device further includes a main control board 304 for executing a control method for a water treatment device as described in any one of the above embodiments.

[0194] In the above embodiment, the main body 102 is provided with a connecting portion 106 for connecting the inside of the cavity 104 with the outside of the cavity 104 ; the water treatment device further comprises: a box 202 for containing a solution, and the main body 102 is disposed in the box 202 .

[0195] Among them, the main body 102 has a connecting portion 106 connected to the cavity 104, so that the solution outside the cavity 104 can enter the cavity 104 through the connecting portion 106. At the same time, the solution entering the cavity 104 can be transferred from the cavity 104 to the outside of the cavity 104 through the connecting portion 106, so as to realize the measurement of the solution concentration in the box 202.

[0196] In one embodiment, there are multiple communicating portions 106 , which are spaced apart along the circumference of the body 102 .

[0197] In one embodiment, there may be multiple boxes 202, wherein the multiple boxes 202 are connected to each other. In this case, the solution concentration in the multiple boxes 202 can be detected. In this process, the solution concentration detection process is simple and low-cost, which facilitates reducing the manufacturing cost of the solution configuration component.

[0198] In one embodiment, after the solution is injected into the tank 202 , the body 102 is immersed in the solution.

[0199] In the above embodiment, the box body 202 has a feed port 204 and a discharge port 206; the water treatment device also includes a spacer 208, which is located in the box body 202, and the spacer 208 separates the box body 202 into a first box body 2022 and a second box body 2024 that are connected. The first box body 2022 is opposite to the feed port 204, and the second box body 2024 is opposite to the discharge port 206. The main body 102 is located in the first box body 2022 or in the second box body 2024.

[0200] In this embodiment, the box body 202 is divided into a first box body 2022 and a second box body 2024 which are connected to each other by a spacer 208 so as to functionally divide the box body 202, that is, the first box body 2022 is opposite to the feed port 204, and the second box body 2024 is corresponding to the discharge port 206, thereby reducing the solute put into the box body 202 from being discharged from the box body 202 through the discharge port 206, affecting the liquid discharge effect of the box body 202, such as the problem that the discharged solution contains large particles of solute or the concentration of the discharged solution fluctuates.

[0201] The main body 102 is disposed in the first box body 2022 to improve the detection rate of the solution concentration. At the same time, the blocking of the discharge port 206 by the main body 102 is reduced, thereby ensuring the smooth discharge of the material.

[0202] The body 102 is disposed in the second box 2024 so that after the liquid put into the first box 2022 is mixed with the solute, the solution diffuses into the second box 2024 for detection by the body 102 in the second box 2024, thereby ensuring the detection accuracy of the solution concentration.

[0203] In addition, since the detection device is arranged in the second box 2024, and the second box 2024 corresponds to the discharge port 206, the concentration of the detected solution can be close to the concentration of the solution discharged from the discharge port 206, thereby accurately knowing the concentration of the discharged solution.

[0204] In one embodiment, the spacer 208 may be a baffle.

[0205] In the above embodiment, the feed port 204 includes a liquid injection port 2042 , and the liquid injection port 2042 is located at the bottom of the first box body 2022 or the top of the first box body 2022 .

[0206] In this embodiment, the position of the injection port 2042 in the feed port 204 is specifically defined to meet the usage needs of different scenarios. Usually, the feed port 204 also includes a delivery port for delivering solutes, and the delivery port is usually arranged at the top of the first box body 2022. By arranging the injection port 2042 at the bottom of the first box body 2022, when the injection port 2042 is used to inject liquid into the first box body 2022, the solute delivered into the first box body 2022 can be flushed, so as to reduce the accumulation of solutes at the bottom of the first box body 2022 and form lumps, thereby accelerating the dissolution rate of the solute.

[0207] The liquid injection port 2042 is disposed at the top of the first box body 2022 so that the liquid injection port 2042 and the injection port are integrated, thereby reducing the design difficulty of the solution configuration component.

[0208] In the above embodiment, when the liquid injection port 2042 is located at the top of the first box body 2022 , the water treatment device further includes: an anti-knotting member 210 , which is provided in the first box body 2022 and located at the bottom of the first box body 2022 .

[0209] In this embodiment, an anti-caking member 210 is provided to prevent the solute put into the first box 2022 from accumulating at the bottom of the first box 2022 to form agglomerates, thereby affecting the dissolution rate of the solute.

[0210] In this embodiment, the anti-agglomeration element 210 can be understood as a structure for inhibiting the solute from agglomerating into agglomerates.

[0211] In one embodiment, the anti-knot element 210 is a structure having a cavity 104 .

[0212] In any of the above embodiments, the spacer 208 has at least one through hole 212 , and the through hole 212 is used to connect the first box body 2022 and the second box body 2024 .

[0213] In this embodiment, by defining at least one through hole 212 on the spacer 208, the through hole 212 is used to accelerate the flow rate of the solution to be detected between the first box body 2022 and the second box body 2024, thereby improving the accuracy of the concentration detected by the detection device.

[0214] In one embodiment, when there are multiple through holes 212 , the multiple through holes 212 are evenly arranged on the spacer 208 .

[0215] In one embodiment, the detection member 110 is located on the box 202 or the spacer 208 .

[0216] In this embodiment, the setting position of the detection member 110 in the box 202 is specifically defined, wherein when the detection member 110 is located on the spacer 208, the detection member 110 can be hidden in the box 202, thereby reducing the space occupied by the detection member 110 outside the box 202.

[0217] By arranging the detection member 110 on the box body 202 , the difficulty of arranging and / or assembling the detection member 110 is reduced.

[0218] Specifically, the detection element 110 is disposed inside the box 202 , and may also be disposed outside the box 202 .

[0219] When the detection member 110 is arranged outside the box 202 , the solute can be reduced from condensing on the detection member 110 , covering the detection member 110 and affecting the detection accuracy of the detection member 110 , thereby ensuring the accuracy of the detection result of the detection member 110 .

[0220] In the above embodiments, the water treatment device includes a washing device or a purification device.

[0221] In one embodiment, the washing device is a dishwasher, the solute is salt, that is, regeneration salt particles, the solution is salt water, and the detection element is a magnetic sensor.

[0222] Among them, the density of salt water with different concentrations is different. The position of the suspension in the cavity will also change with the change of the concentration of the salt water. The distance between the magnetic sensor and the suspension (strong magnet) is different, and the magnetic field strength detected by the magnetic sensor is different. The detected magnetic field is converted into the concentration of the salt water (regardless of the concentration density).

[0223] like Figure 6 As shown, tap water is injected into the box through the injection port, and the concentration of salt water is close to that of tap water. At this time, the concentration of salt water is relatively low, the density of the suspended part is greater than the concentration of salt water, and the suspended part is at the bottom of the cavity. At this time, the magnetic sensor is far away from the strong magnetic field, and the detected magnetic field strength is the weakest.

[0224] like Figure 7 As shown in the figure, after the regenerated granular salt dissolves in the brine for a period of time, the concentration and density of the brine begin to slowly increase, and the suspension begins to gradually rise in the cavity as the concentration of the brine increases. At this time, the magnetic sensor detects that the magnetic field strength signal gradually increases. The main control board converts the corresponding height of the suspension and the corresponding density and concentration of the brine according to the signal strength of the magnetic sensor.

[0225] When the regenerated granular salt naturally dissolves in the brine, and the concentration and density of the brine reach the set values ​​designed for the system, the main control board calculates the corresponding height of the suspension and the corresponding density and concentration of the brine based on the signal strength of the magnetic sensor. When the magnetic field strength is equal to the magnetic field strength corresponding to the set concentration, the main control board can control the regeneration system to start regenerating the soft water resin by extracting brine.

[0226] like Figure 8 As shown, as time goes by, the more salt water is extracted, the lower the position of the suspension in the cavity will be. During the process of extracting salt water, the main control board calculates the corresponding height of the suspension according to the signal strength of the magnetic sensor. When the magnetic field strength is equal to the minimum magnetic field strength, it means that the salt water has been extracted, and the main control board controls the pump to stop extracting salt water.

[0227] like Fig.12 As shown, the control logic of the dishwasher is as follows:

[0228] Step 1202, start water injection;

[0229] Step 1204, detecting magnetic intensity;

[0230] Step 1206, fitting the natural dissolution magnetic intensity curve;

[0231] Step 1208, determine whether the set value and the curve meet the rule, if the determination result is yes, execute step 1210, if the determination result is no, execute step 1212;

[0232] Step 1210, start pumping;

[0233] Step 1212, the system starts timing and executes step 1204;

[0234] Step 1214, detecting magnetic intensity;

[0235] Step 1216, fitting the natural dissolution magnetic intensity curve;

[0236] Step 1218, determine whether the minimum value and the curve meet the rule, if the determination result is yes, execute step 1220, if the determination result is no, execute step 1222;

[0237] Step 1220, stop pumping;

[0238] Step 1222, system timing, execute step 1214.

[0239] Among them, after the water injection is completed, the concentration of the salt water is close to the concentration of tap water, the concentration of the salt water is relatively low, the density of the suspended parts is greater than the concentration of the salt water, and the suspended parts are at the bottom of the cavity. At this time, the magnetic sensor detects the weakest magnetic field strength signal. Over time, the regenerated salt particles gradually dissolve, the concentration of the salt water gradually increases, and the suspended parts gradually float up with the increase in the concentration of the salt water. The magnetic field strength signal detected by the magnetic sensor also gradually becomes stronger over time; the magnetic field strength signal detected by the magnetic sensor is curve-fitted with time, and it is determined whether the slope is within the set range (affected by temperature, number of salt particles, etc.); when the magnetic field strength detected by the magnetic sensor reaches the set value and the fitting curve satisfies the law, salt water is extracted; during the process of extracting salt water, the signal strength of the magnetic sensor gradually weakens, and curve fitting is performed at the same time, and it is determined whether the slope is within the set range (affected by factors such as pumping speed and resin hardening degree). When the magnetic field strength is equal to the minimum magnetic field strength and the fitting degree satisfies the law, it means that the salt water has been extracted and the extraction of salt water stops.

[0240] The setting range is the first slope interval and the second slope interval mentioned above, the setting value is the first detection result mentioned above, and the minimum magnetic field strength is the second detection result.
