Description

A water quality testing method, apparatus, electronic device, and storage medium Technical Field

[0001] This application relates to the field of water quality testing technology, and in particular to a water quality testing method, apparatus, electronic device, and storage medium. Background Technology

[0002] With the development of smart refrigerators, more and more refrigerators on the market now have ice-making compartments. However, frequent door openings and the insertion of various foods can lead to water quality deterioration in the refrigerator compartment's water tank if the water isn't changed promptly. This is especially true in winter when the ice-making compartment is used much less frequently, and users may forget there's water in the tank. When they finally need to use it, they not only have to change the water but also clean the tank, resulting in a poor user experience. In daily life, we can only rely on our senses to judge the water quality, and the accuracy of this method is questionable. Frequent water changes not only waste water but also require continuous monitoring by the user.

[0003] In existing technologies, water quality testing methods mainly include subjective judgment or detection of chloride ion concentration using sensors. Subjective judgment relies solely on taste or smell, which can introduce errors. The water may already be deteriorating, making timely intervention impossible. Furthermore, frequent tank replacements based on intuition increase costs and waste resources. Sensor-based chloride ion concentration detection only involves the water quality testing device, not the specific detection method, leading to lower accuracy and impacting user experience.

This method can automatically detect the water quality in the water tank of a refrigerator's ice-making compartment, avoiding situations where changes in water quality within the ice-making compartment go undetected, improving the accuracy of water quality testing, and ensuring the safe use of water.

It should be understood that such information can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0020] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display, data used for analysis, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0021] In existing technologies, water quality testing methods mainly include subjective judgment or detection of chloride ion concentration using sensors. Subjective judgment relies solely on taste or smell, which can introduce errors. The water may already be deteriorating, making timely intervention impossible. Furthermore, frequent tank replacements based on intuition increase costs and waste resources. Sensor-based chloride ion concentration detection only involves the water quality testing device, not the specific detection method, leading to lower accuracy and impacting user experience.

[0022] Please refer to Figure 1, which shows a flowchart of a water quality testing method provided in an embodiment of this application. This application provides the operation steps of the method described in the embodiment or flowchart, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiment is only one of many possible execution orders and does not represent the only execution order. The water quality testing method can be executed in the order shown in the embodiment or the figure. Specifically, as shown in Figure 1, the method may include the following steps: S101: Obtain at least one total dissolved solids concentration value of the water to be tested in the target ice-making chamber within a preset time period; In this embodiment, when the total dissolved solids (TDS) is measured in milligrams per liter (mg / L), it indicates how many milligrams of total dissolved solids are dissolved in 1 liter of water; when the measurement unit is ppm solution parts per million, it refers to the number of milliliters of solute contained in 1 million milliliters of solution or indicates the number of grams of solute contained in 1 million grams of solution, and 1 mg / L = 1 ppm. According to the national standard GB5749-2006 "Standards for Drinking Water Quality," there is a limit to the total dissolved solids (TDS) in drinking water: ≤1000 mg / L. A higher TDS value indicates a greater amount of dissolved matter in the water, signifying a greater degree of change in water quality. Therefore, to determine whether the water quality of a test water body has changed, at least one TDS concentration value can be obtained from the test water body within a preset time period. This at least one TDS concentration value within the preset time period can be obtained by testing the test water body at preset time intervals or by performing a preset number of tests within the preset time period. For example, if the preset time period is 10 seconds, testing the test water body at preset time intervals of 2 seconds will yield 5 TDS concentration values; similarly, testing the test water body 5 times will also yield 5 TDS concentration values.

[0023] It should be noted that the preset time period, preset time interval, and preset number of times can be set according to actual needs, and no specific limitations are made here. Any method that can obtain the total dissolved solids concentration value of the water body to be tested within the preset time period is included in this application.

[0024] In some exemplary embodiments, before obtaining the total dissolved solids concentration value of the water to be tested in the target ice-making chamber, the method further includes: determining whether the water volume of the water to be tested in the target ice-making chamber has reached a preset water volume; if the water volume of the water to be tested has not reached the preset water volume, waiting for a preset time; repeating the following steps: determining whether the water volume of the water to be tested in the target ice-making chamber has reached the preset water volume; if the water volume of the water to be tested has not reached the preset water volume; until the water volume of the water to be tested in the target ice-making chamber reaches the preset water volume.

[0025] Specifically, before obtaining the total dissolved solids concentration value of the water body to be tested within a preset time period, it is necessary to first determine whether the water body to be tested in the target ice-making chamber meets the testing requirements, that is, whether the water volume of the water body to be tested has reached the preset water volume. If the preset water volume has not been reached, it indicates that there is no water body to be tested in the target ice-making chamber or the existing water body to be tested is insufficient for water quality testing. In this case, wait for the preset time. The preset time can be 5 seconds, 10 seconds or other times, and there is no specific limitation here. After waiting for the preset time, continue to determine whether the water body to be tested has reached the preset water volume. If it has not reached the preset water volume, continue to wait for the preset time until the water body to be tested reaches the preset water volume, and then the water quality testing operation can be performed.

[0026] By assessing the volume of water in the ice-making chamber before obtaining the total dissolved solids concentration value of the water body to be tested within a preset time period, it is possible to ensure that the water quality test is conducted under the condition that the water body meets the requirements, thereby avoiding errors in water quality testing caused by factors such as insufficient water volume and improving the accuracy of water quality testing.

[0027] S103: Based on the at least one total dissolved solids concentration value, determine the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period. In this embodiment, electrical conductivity (EC) is a numerical representation of the ability of a solution to conduct current; it characterizes the purity of water, and the commonly used unit is μs / cm (micro-Siemens per centimeter). Since the number of total dissolved solids concentration values ​​varies, it is necessary to calculate the corresponding target conductivity of the water body to be tested within the preset time period based on the number of total dissolved solids concentration values.

[0028] In some exemplary embodiments, please refer to Figure 2, which shows a flowchart of a method for determining target conductivity provided by an embodiment of this application. Specifically, as shown in Figure 2, the step of determining the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period based on the at least one total dissolved solids concentration value includes: S201: Obtaining the conversion relationship between the total dissolved solids concentration value and conductivity; In the above exemplary embodiments, specifically, the conversion relationship between the total dissolved solids concentration value TDS and the conductivity EC is as follows: 1ppm TDS = 2us / cm EC where TDS is the total dissolved solids concentration value, ppm is the unit of the total dissolved solids concentration value, EC is the conductivity, andus / cm is the unit of conductivity. The conversion relationship shows that the ratio between the total dissolved solids concentration value and the conductivity is 1:2.

[0029] S203: When there is only one total dissolved solids concentration value, the conductivity corresponding to the total dissolved solids concentration value is calculated based on the conversion relationship. In the above exemplary embodiment, specifically, if there is only one total dissolved solids concentration value of the water body to be tested within a preset time period, the total dissolved solids concentration value is directly converted into the corresponding conductivity. For example, when the total dissolved solids concentration value is 580 ppm, the corresponding conductivity after conversion is 1160 μS / cm.

[0030] S205: The conductivity is determined as the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period.

[0031] In the above exemplary embodiment, specifically, when there is only one total dissolved solids concentration value of the water body to be tested within a preset time period, the conductivity after converting the total dissolved solids concentration value is the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period. For example, if there is only one total dissolved solids concentration value, and its value is 580 ppm, the corresponding conductivity after conversion is 1160 μS / cm, and the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period is 1160 μS / cm.

[0032] When there is only one total dissolved solids concentration value, the conductivity corresponding to the total dissolved solids concentration value is calculated by using the conversion relationship between the total dissolved solids concentration value and conductivity, and this conductivity is determined as the target conductivity of the water body to be tested in the target ice-making chamber within a preset time period, thereby providing more accurate conductivity data for subsequent water quality testing.

[0033] In some exemplary embodiments, please refer to Figure 3, which shows a flowchart of another method for determining target conductivity provided by an embodiment of this application. Specifically, as shown in Figure 3, the method further includes: 301: when there are multiple total dissolved solids concentration values, calculating the conductivity corresponding to each of the multiple total dissolved solids concentration values ​​based on the conversion relationship; in the above exemplary embodiments, specifically, if there are multiple total dissolved solids concentration values ​​of the water body to be tested within a preset time period, calculating the conductivity corresponding to each total dissolved solids concentration value. For example, if the total dissolved solids concentration of the water body to be tested is detected according to a preset time period of 10s and a preset time interval of 2s, five total dissolved solids concentration values ​​can be obtained: 980ppm, 1100ppm, 1320ppm, 1210ppm, and 1045ppm. Then, the conductivity corresponding to each total dissolved solids concentration value is 1960us / cm, 2200us / cm, 2640us / cm, 2420us / cm, and 2090us / cm, respectively.

[0034] S303: The conductivity corresponding to the plurality of total dissolved solids concentration values ​​is averaged to obtain the average conductivity of the plurality of total dissolved solids concentration values; In the above exemplary embodiment, specifically, the conductivity corresponding to the above 5 total dissolved solids concentration values ​​can be averaged to obtain the average conductivity of the 5 total dissolved solids concentration values ​​as (1960 + 2200 + 2640 + 2420 + 2090) / 5 = 2262 μS / cm.

[0035] S305: The average conductivity is determined as the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period.

[0036] In the above exemplary embodiment, specifically, after calculating the average conductivity of the five total dissolved solids concentration values, the average conductivity is determined as the target conductivity of the water to be tested in the target ice-making chamber within a preset time period. That is, the target conductivity of the water to be tested in the target ice-making chamber within the preset time period is 2262 μS / cm.

[0037] When there are multiple total dissolved solids (TDS) concentration values, the conductivity corresponding to each TDS concentration value is calculated based on the conversion relationship between TDS and conductivity. The multiple conductivity values ​​are then averaged, and the resulting average conductivity is determined as the target conductivity of the water in the target ice-making chamber within a preset time period. This avoids detection errors caused by sudden anomalies and provides more accurate conductivity data for subsequent water quality testing.

[0038] S105: The target conductivity is compared with a preset conductivity threshold to obtain the freshness level of the water body to be tested. In this embodiment, after calculating the target conductivity of the water body to be tested in the target ice-making chamber within a preset time period, the target conductivity is compared with the preset conductivity threshold, and the freshness level of the water body to be tested is determined based on the comparison result. The preset conductivity threshold is set according to actual conditions. For example, according to the "Standards for Drinking Water Quality GB579-2006", the standard conductivity limit for drinking water is no greater than 2000 μS / cm, meaning the preset conductivity threshold can be 2000 μS / cm.

[0039] In some exemplary embodiments, comparing the target conductivity with a preset conductivity threshold to obtain the freshness level of the water body to be tested includes: determining the freshness level of the water body to be tested as Level 1 freshness when the target conductivity is less than or equal to the preset conductivity threshold; and determining the freshness level of the water body to be tested as Level 2 freshness when the target conductivity is greater than the preset conductivity threshold.

[0040] In the above exemplary embodiments, specifically, the freshness level can include Level 1 freshness and Level 2 freshness. If the target conductivity is less than or equal to the preset conductivity threshold, it indicates that the water body meets the drinking water hygiene standards, and the freshness level of the water body is determined to be Level 1 freshness. If the target conductivity is greater than the preset conductivity threshold, it indicates that the water body does not meet the drinking water hygiene standards, and the freshness level of the water body is determined to be Level 2 freshness. For example, in the above exemplary embodiments, when the target conductivity is 1160 μS / cm, it is less than the preset conductivity threshold of 2000 μS / cm, and the freshness level of the water body is Level 1 freshness; when the target conductivity is 2262 μS / cm, it is greater than the preset conductivity threshold of 2000 μS / cm, and the freshness level of the water body is Level 2 freshness.

[0041] By comparing the target conductivity with a preset conductivity threshold, different freshness levels of the water body to be tested are determined based on different comparison results. This allows the water body to be tested to be distinguished according to freshness conditions, enabling accurate measurement of the water quality and ensuring more precise water quality testing.

[0042] S107: Determine the water quality test result of the water body to be tested based on the freshness level.

[0043] In this embodiment, there is a one-to-one correspondence between the freshness level and the water quality test results. The freshness level can include first-level freshness and second-level freshness. Correspondingly, the water quality test results can include normal water quality and abnormal water quality.

[0044] In some exemplary embodiments, determining the water quality test result of the water body to be tested based on the freshness level includes: determining the water quality test result of the water body to be tested as normal when the freshness level is Level 1; and determining the water quality test result of the water body to be tested as abnormal when the freshness level is Level 2.

[0045] In the above exemplary embodiments, specifically, since there is a one-to-one correspondence between freshness grades and water quality test results, where freshness grades can include Level 1 freshness and Level 2 freshness, and water quality test results can include normal water quality and abnormal water quality, if the freshness grade of the water body to be tested is Level 1 freshness, it indicates that the water body meets the drinking water hygiene standards, and the water quality test result is normal; if the freshness grade of the water body to be tested is Level 2 freshness, it indicates that the water body does not meet the drinking water hygiene standards, and the water quality test result is abnormal.

[0046] Determining the water quality test results of the water body by classifying its freshness level can accurately measure the water quality status of the water body, thereby providing precise data support for subsequent operations based on the water quality test results and improving the user experience.

[0047] In some exemplary embodiments, the method further includes: generating a reminder message based on the water quality test results; and displaying the reminder message on the refrigerator's display screen to prompt the user to perform a corresponding operation.

[0048] In the above exemplary embodiment, specifically, after water quality testing is performed on the water body to be tested and the water quality test results are obtained, corresponding reminder information is generated and displayed based on the water quality test results. The reminder information can be a text reminder indicating normal / abnormal water quality, or a data reminder regarding the target conductivity of the water body to be tested. Furthermore, the reminder information can be displayed on the refrigerator's screen in ways including, but not limited to, text warning messages and color-coded indicators (red / yellow warning icons).

[0049] By generating corresponding reminders based on water quality test results and displaying these reminders on the refrigerator's screen, users can be promptly reminded to perform appropriate operations. This ensures that the water in the ice-making compartment is replaced in a timely manner, preventing water deterioration from affecting user use and avoiding resource waste caused by subjective user judgment, thereby improving the user experience.

[0057] In an optional embodiment, the water quality testing device further includes: a reminder information generation module for generating reminder information based on the water quality testing results; and a display module for displaying the reminder information on the refrigerator's display screen to prompt the user to perform corresponding operations.

[0059] Please refer to Figure 6, which shows a flowchart of a method for automatically detecting water quality and reminding users to change water in the ice maker of a refrigerator according to an embodiment of this application. As shown in Figure 6, the method includes: S601: Initializing the water quality detection device; specifically, the water quality detection device can be initialized, and the initialization operation can include setting the parameters required for water quality detection.

[0060] S602: Determine whether the water volume of the water to be tested in the target ice-making chamber has reached the preset water volume; specifically, determine the next operation to be performed by determining whether the water volume of the water to be tested has reached the preset water volume.

[0061] S603: If the water volume of the water body to be tested does not reach the preset water volume, wait for a preset time; specifically, if the water volume does not reach the preset water volume, it indicates that there is no water body to be tested in the target ice-making chamber or the existing water body to be tested is insufficient for water quality testing, then the operation of waiting for the preset time is executed.

[0062] S604: Repeat steps S602 to S603 until the water volume of the water to be tested in the target ice-making chamber reaches the preset water volume, and obtain at least one total dissolved solids concentration value of the water to be tested in the target ice-making chamber within a preset time period; specifically, after waiting for a preset time, continue to determine whether the water volume to be tested has reached the preset water volume. If it has not reached the preset water volume, continue to wait for the preset time until the water volume to be tested reaches the preset water volume, indicating that the water quality testing operation can be performed, that is, the total dissolved solids concentration value of the water to be tested in the target ice-making chamber within a preset time period can be obtained through the water quality testing device, wherein the number of total dissolved solids concentration values ​​is at least one.

[0063] S605: Based on the at least one total dissolved solids concentration value, the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period is obtained; specifically, after obtaining at least one total dissolved solids concentration value, the target conductivity of the water body to be tested in the target ice-making chamber within the preset time period is calculated based on the obtained total dissolved solids concentration value.

[0064] S606: The target conductivity is compared with a preset conductivity threshold to obtain the freshness level of the water body to be tested; specifically, the freshness level of the water body to be tested at the target conductivity is determined according to the relationship between the target conductivity and the preset conductivity threshold.
