Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a method, apparatus, system for detecting abnormal rotation of a solenoid valve, as well as a water purification device. Background Technology

[0002] The lifespan of a water purifier filter cartridge is directly related to the quality of the local water. After a certain period of use, the filter cartridge needs to be automatically flushed periodically. The size of the water flow during flushing is directly related to the diameter of the solenoid valve pipeline at the wastewater end of the reverse osmosis membrane filter cartridge.

[0003] Currently, most mainstream water purifiers on the market use solenoid valves with fixed orifice diameters and specifications. Circuit control simply involves switching the valve on and off; it opens during flushing and closes during water production. For solenoid valves with a fixed wastewater ratio, in areas with good water quality, flushing at the same frequency and flow rate, with a fixed filter lifespan, will result in relatively high water consumption during overall flushing. However, in areas with poor water quality, flushing at the same frequency and flow rate can easily clog the wastewater solenoid valve.

[0004] To address the aforementioned issues, a novel adjustable wastewater ratio solenoid valve is used. The rotation angle of the solenoid valve is controlled by software, adjusting to the appropriate angle based on the water quality level to initiate the water purifier's flushing process. However, since the adjustable wastewater ratio solenoid valve can only be controlled according to predetermined parameters, variations in water quality and structural assembly can lead to misalignment and incomplete rotation.

[0005] In existing methods, the detection of the adjustable wastewater ratio solenoid valve is mainly achieved by adding an abnormality detection device. This method is costly and increases the structural complexity of the water purification equipment, making it difficult to assemble. Summary of the Invention

[0027] The average flow velocity of the water passing through the solenoid valve to be tested within the second preset time period is calculated as the water flow velocity of the solenoid valve to be tested.

[0028] In one embodiment, the method further includes:

[0029] If the continuous operating time of the water purification equipment is greater than or equal to a preset time threshold or the water quality parameters of the water purification equipment are greater than or equal to a preset water quality parameter threshold, the detection thresholds and rotation parameters corresponding to each gear of the solenoid valve to be tested are updated according to the current water quality parameters of the water purification equipment.

[0030] Secondly, this application also provides a solenoid valve rotation abnormality detection device, comprising:

[0031] The gear position determination module is used to determine the gear position of the solenoid valve to be tested in the water purification equipment.

[0032] The parameter acquisition module is used to acquire the detection threshold and rotation parameters associated with the solenoid valve position.

[0036] Fourthly, this application also provides a water purification device, characterized in that it includes the electromagnetic valve rotation abnormality detection system described in the third aspect.

Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0055] The solenoid valve rotation abnormality detection method provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown. Figure 1 A structural block diagram of a water purification device employing an adjustable wastewater ratio solenoid valve is provided. (See diagram below.) Figure 1 As shown, the water purification equipment includes a pre-filter 110, a flow meter 120, a TDS probe 130, an inlet solenoid valve 140, a pressure stabilizing pump 150, a reverse osmosis membrane filter 160, an adjustable wastewater ratio solenoid valve 170, and a post-filter 180.

[0056] The raw water inlet pipe connects sequentially to the pure water inlet pipe via a pre-filter 110, a flow meter 120, a TDS probe 130, an inlet solenoid valve 140, a pressure stabilizing pump 150, a reverse osmosis membrane filter 160, and a post-filter. The raw water inlet pipe is used to receive raw water, while the pure water inlet pipe is used to output pure water.

[0057] The raw water inlet pipe connects sequentially to the wastewater inlet pipe via a pre-filter cartridge 110, a flow meter 120, a TDS probe 130, an inlet solenoid valve 140, a pressure stabilizing pump 150, a reverse osmosis membrane filter cartridge 160, and an adjustable wastewater ratio solenoid valve 170. The wastewater inlet pipe is used to output wastewater.

[0058] Specifically, after the raw water is connected to the water purification equipment, it is filtered through the pre-filter 110, the reverse osmosis membrane filter 160, and the post-filter 180 to obtain filtered pure water and filtered wastewater, respectively.

[0059] In practical use, the flow meter 120 can be used to detect the flow rate of the water purification equipment 120 after the raw water is connected. The Total Dissolved Solids (TDS) probe is used to detect the TDS value of the raw water in the pipeline. The inlet solenoid valve 140 is used to restrict the flow direction of the raw water in the pipeline to prevent backflow. The pressure stabilizing pump 150 is used to provide pressure for the transmission of water in the pipeline. The adjustable wastewater ratio solenoid valve 170 is used to control the water purification equipment to discharge wastewater according to a fixed flow rate ratio. In some embodiments, the TDS probe 130 also has a temperature measuring accessory, which can be used to detect the temperature value of the water in the pipeline.

[0060] It should be noted that existing water purification equipment includes both water purification equipment using adjustable wastewater ratio solenoid valves and water purification equipment using fixed wastewater ratio solenoid valves.

[0061] like Figure 2 As shown, a water purification device employing a fixed wastewater ratio solenoid valve is provided. Specifically, Figure 2 The water purification equipment shown includes a first wastewater solenoid valve 210, a second wastewater solenoid valve 220, a third wastewater solenoid valve 230, and a flushing solenoid valve 240. The first wastewater solenoid valve 210 is a single-position solenoid valve with an opening angle of 270° and a water flow rate of 600cc. The second wastewater solenoid valve 220 is a two-position solenoid valve with an opening angle of 180° and a water flow rate of 800cc. The third wastewater solenoid valve 230 is a three-position solenoid valve with an opening angle of 90° and a water flow rate of 1050cc. The flushing solenoid valve 240 is opened during the flushing step of the water purification equipment to flush impurities from the wastewater pipes.

[0062] Compared to water purification equipment that uses a fixed wastewater ratio solenoid valve, water purification equipment that uses an adjustable wastewater ratio solenoid valve can change the switching position according to the water quality parameters or water flow in the water purification equipment pipeline. This can effectively save the flushing water volume of the water purification equipment and ensure smooth wastewater discharge, avoiding clogging of the water purification equipment.

[0063] Those skilled in the art will understand that Figure 1 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the water purification equipment to which the present application is applied. Specific water purification equipment may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0064] In practical applications, abnormal rotation of the adjustable wastewater ratio solenoid valve in a water purification system can negatively impact water quality. Therefore, detecting abnormal rotation of this valve is crucial, directly affecting the safety of the water in the purification system. This embodiment proposes a method for detecting abnormal solenoid valve rotation. This method enables accurate detection of abnormal rotation of the adjustable wastewater ratio solenoid valve used in water purification systems at low cost, effectively ensuring the safety of the water in the purification system.

[0065] In one embodiment, such as Figure 3 As shown, a method for detecting abnormal rotation of a solenoid valve is provided, which can be applied to... Figure 1 Taking a water purification device as an example, the explanation includes the following steps:

[0066] S301, Determine the solenoid valve position of the solenoid valve to be tested in the water purification equipment;

[0067] Specifically, the solenoid valve to be tested in this embodiment can be an adjustable wastewater ratio solenoid valve in a water purification device, or it can be any other solenoid valve with adjustable settings. This embodiment uses an adjustable wastewater ratio solenoid valve as the solenoid valve to be tested for illustration, but it is not the only one.

[0068] The adjustable wastewater ratio solenoid valve can be configured with multiple speed settings to meet the wastewater discharge flow requirements of specific application scenarios. For example, the adjustable wastewater ratio solenoid valve can include three adjustable speed settings: low speed, medium speed, and high speed. Specifically, when the adjustable wastewater ratio solenoid valve is in low speed mode, the corresponding flow rate can be 600cc. When the adjustable wastewater ratio solenoid valve is in medium speed mode, the corresponding flow rate can be 800cc. When the adjustable wastewater ratio solenoid valve is in high speed mode, the corresponding flow rate can be 1050cc. It should be noted that the number of speed settings of the adjustable wastewater ratio solenoid valve can be configured according to the actual application scenario, and is not limited to three. Furthermore, the flow rate corresponding to each speed setting can also be determined based on the type of solenoid valve used in the actual application scenario, without specific limitations.

[0069] Specifically, there are two application scenarios for determining the solenoid valve setting. The first scenario is when the water purifier is powered on for the first time, before the water purification process begins. In this case, determining the solenoid valve setting requires the water purifier to run for a period of time to determine the current solenoid valve setting based on the raw water parameters. This method of determining the solenoid valve setting based on raw water parameters is a scheme configured according to the automatic adjustment mode of the adjustable wastewater ratio solenoid valve. It can be used when the processor has not memorized the solenoid valve setting, i.e., when the water purifier is powered on for the first time.

[0070] The second scenario involves adjusting the water purification equipment's settings. The solenoid valve setting is determined based on the water flow rate from the wastewater outlet. At this point, the water purification equipment has already begun the water production process, and the adjustable wastewater ratio solenoid valve has discharged wastewater. This means the solenoid valve setting has been changed, and the processor stores the previously memorized setting. When determining the solenoid valve setting, the previously memorized setting can be directly used as the current setting for the adjustable wastewater ratio solenoid valve.

[0071] S302, obtain the detection threshold and rotation parameters associated with the solenoid valve position;

[0072] Specifically, each solenoid valve position is associated with a corresponding detection threshold and rotation parameters. The detection thresholds include preset flow rate range, temperature threshold, flow rate threshold, and pressure threshold, while the rotation parameters include the solenoid valve rotation angle and the initial rotation angle of the solenoid valve.

[0073] For example, in low speed mode, the preset flow rate range associated with the solenoid valve position is 600cc ± 20cc, and the associated rotation angle is 270°. In medium speed mode, the preset flow rate range associated with the solenoid valve position is 800cc ± 20cc, and the associated rotation angle is 180°. In high speed mode, the preset flow rate range associated with the solenoid valve position is 1050cc ± 20cc, and the associated rotation angle is 90°.

[0074] It should be noted that the detection threshold and rotation parameters associated with different solenoid valve positions can be configured with specific values ​​according to the needs of the actual application scenario. The above examples are only used to represent one application scenario and are not intended to limit the application.

[0075] In one embodiment, the pressure threshold can be used to detect whether the flow rate of water in the pipeline is normal. For example, the standard pressure range of the water purification equipment during use is 0.1 to 0.4 MPa. If the water pressure exceeds this standard pressure range, it can be determined that the pressure stabilizing pump of the water purification equipment is abnormal.

[0076] S303 controls the solenoid valve under test to rotate to the target angle according to the rotation parameters, and collects the water flow velocity passing through the solenoid valve under test;

[0077] Specifically, in this embodiment, after obtaining the rotation parameters corresponding to the solenoid valve position, the solenoid valve to be tested is controlled to rotate to the corresponding target angle according to the rotation parameters, and the flow velocity of the water passing through the solenoid valve to be tested is detected by a flow meter. Thus, based on the correspondence between the water flow velocity and the solenoid valve position, it can be further determined whether the adjustable wastewater ratio solenoid valve has rotated to the target angle.

[0078] S304, determine whether the solenoid valve under test is abnormal based on the water flow velocity and the detection threshold.

[0079] Specifically, when the water flow velocity corresponds to the detection threshold, it indicates that the adjustable wastewater ratio solenoid valve has rotated to the target angle, and it can be determined that the adjustable wastewater ratio solenoid valve is in normal condition.

[0080] When the water flow velocity does not correspond to the detection threshold, it indicates that the adjustable wastewater ratio solenoid valve has not rotated to the target angle, and it can be determined that the adjustable wastewater ratio solenoid valve is in an abnormal state.

[0081] In summary, this embodiment provides a method for detecting abnormal rotation of a solenoid valve. By proposing a new detection procedure, it is possible to detect abnormal rotation of the adjustable wastewater ratio solenoid valve of the water purification equipment without adding additional detection equipment and solenoid valve switches. By judging the water flow rate of the adjustable wastewater ratio solenoid valve at the corresponding setting, it is possible to accurately determine whether the adjustable wastewater ratio solenoid valve is unable to rotate to the corresponding angle, effectively ensuring the water quality safety of the water purification equipment and improving the self-inspection efficiency of the water purification equipment under low cost conditions.

[0082] In one embodiment, such as Figure 4 As shown, S304 includes:

[0083] S305, if the water flow velocity is within the preset flow velocity range, the solenoid valve under test is confirmed to be normal.

[0084] Specifically, the preset flow rate range is a preset flow rate threshold ± a fixed flow rate deviation value. The preset flow rate threshold is a reference flow rate value set for each flow rate level, and the fixed flow rate deviation value is a detection accuracy that can be configured according to the actual application scenario. The smaller the fixed flow rate deviation value, the higher the accuracy of this embodiment in detecting rotational anomalies; conversely, the larger the fixed flow rate deviation value, the lower the accuracy of this embodiment in detecting rotational anomalies. Users can configure the fixed flow rate deviation value according to the needs of the actual application scenario; this embodiment does not impose any limitations on this.

[0085] If the water flow velocity is within the preset flow velocity range, it can be determined that the solenoid valve under test is in a normal state. In this embodiment, when it is determined that the solenoid valve under test is in a normal state, all detection parameters used to determine whether the solenoid valve under test is abnormal will be reset, such as the number of flow velocity detections and the first preset time.

[0086] S306, If the water flow velocity does not fall within the preset flow velocity range, determine the number of flow velocity detections.

[0087] Specifically, if the water flow velocity is not within the preset flow velocity range, it can be determined that the current water flow velocity collected does not meet the current gear requirement of the adjustable wastewater ratio solenoid valve. In this case, it is necessary to further identify and determine which test the water flow velocity value is from.

[0088] S307, if the number of flow rate detections exceeds the threshold, the solenoid valve under test is determined to be abnormal.

[0089] Specifically, if the number of flow rate detections exceeds the threshold, it can be determined that the solenoid valve under test is malfunctioning. When it is determined that the solenoid valve under test is in an abnormal rotation state, the adjustable wastewater ratio solenoid valve cannot discharge wastewater according to the preset setting. The water purification equipment can display the fault information of the adjustable wastewater ratio solenoid valve and remind the user to replace it to ensure the safety of the water quality in the water purification equipment.

[0090] In one embodiment, if the number of flow rate detections is less than or equal to a threshold number, the method for detecting abnormal rotation of the solenoid valve includes:

[0091] The steps include controlling the rotation of the solenoid valve under test to the target angle according to the rotation parameters, and collecting the water flow velocity through the solenoid valve under test.

[0092] Increase the number of flow rate detections and execute the step of determining whether the solenoid valve under test is abnormal based on the water flow rate and detection threshold.

[0093] Specifically, the step of increasing the number of flow rate detections can be performed as the flow rate detection count index +1 step.

[0094] In this embodiment, when the number of flow rate detections is less than or equal to the threshold number, steps S303 and S304 will be re-executed to determine the abnormal state of the solenoid valve through multiple tests, thereby further ensuring the accuracy of the abnormal state detection of the solenoid valve.

[0095] In practical applications, this embodiment sets the number of flow rate detections. Each time an anomaly is determined for the solenoid valve under test based on the water flow rate and a detection threshold, the number of flow rate detections for the current test must be identified. For example, if the threshold is set to 2, the solenoid valve is determined to be abnormal only if the current water flow rate is the same as the flow rate obtained in the third test and is not within the preset flow rate range.

[0096] It should be noted that the threshold number of detections can be adaptively configured according to the needs of the actual application scenario, and is not limited here. In one embodiment, the flow rate detection count is reset to zero each time the solenoid valve under test is determined to be in a normal state.

[0097] In one embodiment, such as Figure 5 As shown, S301 includes:

[0098] S502, after controlling the water purification equipment to produce water for the first preset time, obtain the water quality parameters of the raw water in the water purification equipment;

[0099] S504, determine the solenoid valve position based on water quality parameters.

[0100] In a specific embodiment, the water quality parameter can be the TDS value or other parameters that can represent the water quality. This embodiment uses the TDS value for explanation, but does not limit the water quality parameter to the TDS value.

[0101] Specifically, for example, water quality parameters can be associated with the solenoid valve setting. When the TDS value is less than or equal to 110, the solenoid valve is set to low speed. When the TDS value is greater than 110 and less than or equal to 650, the solenoid valve is set to medium speed. When the TDS value is greater than 650, the solenoid valve is set to high speed.

[0102] Specifically, after detecting the specific values ​​of the water quality parameters, the current solenoid valve position of the solenoid valve to be tested can be determined based on the correspondence between the specific values ​​of the water quality parameters and the solenoid valve position.

[0103] In this embodiment, through S502 and S504, the current solenoid valve position of the adjustable wastewater ratio solenoid valve can be determined by an automatic configuration identification method when the water purification equipment is powered on for the first time.

[0104] In one embodiment, such as Figure 6 As shown, S303 includes:

[0105] S602, controls the solenoid valve under test to reset to its initial rotation angle;

[0106] S604 controls the solenoid valve under test to rotate from the initial rotation angle to the target angle according to the rotation parameters.

[0107] Specifically, when controlling the solenoid valve under test to rotate, the solenoid valve is first reset and rotated to the initial rotation angle according to step S602. For example, it is rotated to the 0° position, and then rotated at a specified angle to the target angle, such as 90°.

[0108] It should be noted that each gear has a corresponding gear rotation angle: 270° for low speed, 180° for medium speed, and 90° for high speed.

[0109] This embodiment, through S602 and S604, ensures that the adjustable wastewater ratio solenoid valve is accurately rotated to the opening angle required for the solenoid valve position, thus ensuring the accuracy of detecting abnormal states of the adjustable wastewater ratio solenoid valve in this embodiment.

[0110] In one embodiment, such as Figure 7 As shown, S303 also includes:

[0111] S702, controls the second preset time for rinsing the water purification equipment;

[0112] S704, calculate the average flow velocity of the water passing through the solenoid valve to be tested within a second preset time period, and use it as the water flow velocity of the solenoid valve to be tested.

[0113] Specifically, when collecting the water flow rate of the adjustable wastewater ratio solenoid valve, it is necessary to control the water purification equipment to perform the flushing function so that the water flows through the solenoid valve to be tested, i.e., the adjustable wastewater ratio solenoid valve, and is discharged from the water purification equipment, thereby ensuring that the collected water flow rate is the water flow rate related to the solenoid valve to be tested.

[0114] In actual use, the second preset time can be determined based on the overall water flow in the water purification equipment pipeline, but this embodiment does not limit this.

[0115] In one embodiment, the method further includes:

[0116] If the continuous operating time of the water purification equipment is greater than or equal to the preset time threshold or the water quality parameters of the water purification equipment are greater than or equal to the preset water quality parameter threshold, the detection thresholds and rotation parameters corresponding to each gear of the solenoid valve to be tested are updated according to the current water quality parameters of the water purification equipment.

[0117] Specifically, when water quality fluctuates in the pipes of a water purification system, or after the system has been running for a long time, it is necessary to adjust the detection thresholds and rotation parameters of each solenoid valve position to match the wastewater discharge plan for the current water quality in the system.

[0118] In a specific embodiment, the detection threshold and rotation parameters can be updated based on the influence of water quality parameters on the adjustable wastewater ratio solenoid valve setting in the actual application scenario.

[0119] In summary, this embodiment proposes a method for detecting abnormal rotation of a solenoid valve. By proposing a new detection procedure, it eliminates the need for additional detection equipment and solenoid valve switches in the water purification equipment. This method can detect abnormal rotation of the adjustable wastewater ratio solenoid valve in the water purification equipment. By determining the water flow rate at the corresponding setting of the adjustable wastewater ratio solenoid valve, it can accurately determine whether the valve is unable to rotate to the corresponding angle, effectively ensuring the water quality safety of the water purification equipment. It also improves the self-inspection efficiency of the water purification equipment at a low cost. Furthermore, the abnormality detection method proposed in this embodiment can effectively improve the accuracy of solenoid valve abnormality detection through multiple tests, ensuring the reliability of the detection results and preventing the waste of maintenance resources.

[0120] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0121] Based on the same inventive concept, this application also provides a solenoid valve rotation abnormality detection device for implementing the solenoid valve rotation abnormality detection method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more embodiments of the solenoid valve rotation abnormality detection device provided below can be found in the limitations of the solenoid valve rotation abnormality detection method described above, and will not be repeated here.

[0122] In one embodiment, such as Figure 8 As shown, a solenoid valve rotation abnormality detection device 800 is provided, including: a gear position determination module 810, a parameter acquisition module 820, a flow rate acquisition module 830, and an abnormality judgment module 840, wherein:

[0123] The gear position determination module 810 is used to determine the gear position of the solenoid valve to be tested in the water purification equipment.

[0124] The parameter acquisition module 820 is used to acquire the detection threshold and rotation parameters associated with the solenoid valve position.
