Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, for example, to a method and device for purifying water, a refrigerator, and a storage medium. Background Art

[0002] As people's living standards continue to improve, the requirements for refrigerators can no longer be satisfied with just refrigerating and freezing food. For example, when the weather is hot, people also have a demand for ice water or ice cubes. At present, a kettle is set in the refrigerator, and an external water source such as drinking water or tap water is connected to the kettle through a water inlet pipe, so that the external water can be stored in the kettle for refrigeration, and ice water is obtained for people to drink. Alternatively, an automatic ice-making device is set in the refrigerator, and ice is made using the water in the kettle to provide ice cubes for users. In order to ensure that the water in the kettle meets the healthy drinking standards, it is usually necessary to purify the external water entering the refrigerator. The related technology sets a multi-stage purification device in the refrigerator, so that when the external water enters the refrigerator, it is purified multiple times by the multi-stage purification device and stored in the kettle, which is convenient for people to drink. However, not all external water has the same water quality. There may be a situation where the water quality of the external water entering the refrigerator is better. In this case, the external water does not need to be evolved multiple times. The water purification device has a fixed service life. In the related art, the external water entering the refrigerator is repeatedly evolved, so that all purification devices are in a state of continuous use, resulting in a shortened service life of all purification devices.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0025] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0026] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0027] The method for purifying water provided in the embodiments of the present disclosure is applied to a refrigerator. The refrigerator has the characteristics of intelligent control, intelligent perception and intelligent application, and the operation process of the refrigerator often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. A water inlet pipe is provided in the refrigerator, and one end of the water inlet pipe is connected to a tap water pipe or a drinking water pipe outside the refrigerator. External water such as tap water or drinking water is connected to the refrigerator through the water inlet pipe. A first purification device and a second purification device are provided in the refrigerator, and the first purification device and the second purification device are both used to purify external water. Among them, the external water is tap water or drinking water connected to the refrigerator.

[0028] Combination Figure 1 As shown, an embodiment of the present disclosure provides a method for purifying water, which is applied to a refrigerator. The method includes:

[0029] Step S101, the refrigerator obtains the water quality of external water. The external water is the water connected to the refrigerator.

[0030] Step S102, when the quality of the external water meets the first preset condition, the refrigerator triggers the first purification device to purify the external water; when the quality of the external water meets the second preset condition, the first purification device and the second purification device are triggered to purify the external water.

[0031] The method for purifying water quality provided by the embodiment of the present disclosure is adopted, by first detecting the water quality of the external water, and then determining the use of the purification device according to the water quality of the external water. That is, when the water quality of the external water meets the first preset condition, the first purification device is used to purify the external water. When the water quality of the external water meets the second preset condition, the first purification device and the second purification device are used to purify the external water. In this way, the external water connected to the refrigerator is purified by the first purification device, which can increase the probability that the purified external water meets the drinking standard. At the same time, the second purification device is used to purify the external water only when the water quality of the external water meets the second preset condition. Thereby, the use frequency of the second purification device can be reduced according to the water quality of the external water, and the use cycle of the second purification device can be extended.

[0032] Further, obtaining the water quality of the external water includes: obtaining the TDS (Total Dissolved Solids) value of the external water. According to the TDS value of the external water, the water quality of the external water is determined. Since the TDS value can reflect the Ca content in the water, 2+ MG 2+、Na + , K + The concentration of dissolved solids in water is 2+ MG 2+ 、Na + , K + The higher the concentration of soluble solids, the worse the water quality. Therefore, the water quality of the external water can be accurately determined by the TDS value of the external water. It is convenient to choose whether to use the second purification device according to the water quality of the external water, thereby reducing the use frequency of the second purification device and extending the use period of the second purification device.

[0033] Furthermore, a first water quality detection sensor is provided in the refrigerator, the first water quality detection sensor is provided in the water inlet pipe, and the first water quality detection sensor is used to detect the TDS value of the external water. Obtaining the TDS value of the external water includes: using the first water quality detection sensor to detect the TDS value of the external water.

[0034] Further, the water quality of the external water is determined according to the TDS value of the external water, including: when the TDS value of the external water is less than or equal to the first set value, the water quality of the external water is determined to be excellent. When the TDS value of the external water is greater than the first set value, and less than or equal to the second set value, the water quality of the external water is determined to be good. When the TDS value of the external water is greater than the second set value, the water quality of the external water is determined to be poor. Among them, the first set value is greater than 60PPM and less than or equal to any value in 100PPM. The second set value is greater than 100PPM and less than or equal to any value in 200PPM. In this way, the water quality of the external water can be accurately determined by the TDS value of the external water.

[0035] Furthermore, when the water quality of the external water meets the first preset condition, the first purification device is triggered to purify the external water, including: when the water quality of the external water is excellent, the first purification device is triggered to purify the external water. In this way, the external water purified by the first purification device can meet the healthy drinking standard, thereby ensuring the safety of the purified external water.

[0036] Further, when the water quality of the external water meets the second preset condition, the first purification device and the second purification device are triggered to purify the external water, including: when the water quality of the external water is good or poor, the first purification device and the second purification device are triggered to purify the external water. In this way, when the water quality is good or poor, the first purification device and the second purification device are used to purify the external water multiple times, which can improve the purification effect of the external water. The purified external water can meet the standards for healthy drinking, thereby further ensuring the safety of the use of the purified external water. Moreover, only when the water quality is poor or good, the second purification device is used to evolve the external water. The frequency of use of the second purification device can be reduced, and the service life of the second purification device can be extended.

[0037] In some embodiments, the first set value is 100 PPM and the second set value is 200 PPM. The TDS value of the external water detected by the first water quality detection sensor is 300 PPM. Since the TDS value of the external water is greater than the second set value, it is determined that the water quality of the external water is poor. When the water quality of the external water is poor, the first purification device and the second purification device are triggered to purify the external water.

[0038] Furthermore, a kettle is provided in the refrigerator, and the kettle is used to store purified external water. After the external water is purified, the method for purifying the water quality also includes: determining the purified external water as purified water, and storing the purified water in the kettle. The water quality of the purified water is obtained at preset time intervals. Within the preset time period, if the water quality of the purified water meets the third preset condition, the refrigerator is controlled to alarm. Among them, the duration corresponding to the preset time period is greater than the preset time. The third preset condition is that the water quality of the purified water is poor. Since the water quality of the purified water is poor in the preset time period, the purified water is prone to produce air pollutants and pollute other internal environments in the refrigerator. Therefore, when the purified water has poor water quality for a period of time, the refrigerator is controlled to alarm, so that the user can promptly understand that the purified water in the kettle is in a state of poor water quality.

[0039] Combination Figure 2 As shown, the embodiment of the present disclosure provides another method for purifying water, which is applied to a refrigerator. The method includes:

[0040] Step S201, the refrigerator obtains the water quality of external water. The external water is the water connected to the refrigerator.

[0041] Step S202, when the water quality of the external water meets the first preset condition, the refrigerator triggers the first purification device to purify the external water; when the water quality of the external water meets the second preset condition, the first purification device and the second purification device are triggered to purify the external water.

[0042] In step S203, the refrigerator determines the purified external water as purified water, and stores the purified water in the kettle.

[0043] Step S204: The refrigerator obtains the water quality of the purified water at preset time intervals.

[0044] Step S205 , when the water quality of the purified water in the refrigerator satisfies the third preset condition within the preset time period, the refrigerator is controlled to sound an alarm.

[0045] The method for purifying water quality provided by the embodiment of the present disclosure is adopted, and the external water connected to the refrigerator is purified by using the first purification device. Only when the water quality of the external water meets the second preset condition, the second purification device is used to purify the external water. The probability that the purified external water meets the drinking standard can be increased. At the same time, the frequency of use of the second purification device is reduced, and the service life of the second purification device is extended. Moreover, within the preset time period, when the water quality of the purified water meets the third preset condition, the refrigerator is controlled to alarm, so that the user can promptly understand that the purified water in the kettle is in a state of poor water quality.

[0046] Further, obtaining the water quality of the purified water includes: obtaining the TDS value of the purified water. According to the TDS value of the purified water, determining the water quality of the purified water. In this way, the water quality of the purified water can be more accurately determined according to the TDS value of the purified water.

[0047] Furthermore, a second water quality detection sensor is provided in the kettle, and the second water quality detection sensor is used to detect the TDS value of the purified water. Obtaining the TDS value of the purified water includes: using the second water quality detection sensor to detect the TDS value of the purified water.

[0048] Further, the water quality of the purified water is determined according to the TDS value of the purified water, including: when the TDS value of the purified water is less than or equal to the first set value, the water quality of the purified water is determined to be excellent. When the TDS value of the purified water is greater than the first set value and less than or equal to the second set value, the water quality of the purified water is determined to be good. When the TDS value of the purified water is greater than the second set value, the water quality of the purified water is determined to be poor.

[0049] Optionally, the refrigerator is provided with a buzzer, and controlling the refrigerator to sound an alarm includes: controlling the buzzer on the refrigerator to sound a buzzer.

[0050] Optionally, controlling the refrigerator to alarm includes: sending an alarm message to a preset terminal. In some embodiments, the preset terminal is a smart phone, a smart watch, a tablet, etc. For example, sending an alarm message to a mobile phone "Warning! The purified water in the kettle in refrigerator A has been of poor quality for five consecutive days!".

[0051] Optionally, the refrigerator is provided with an alarm indicator light, and controlling the refrigerator to alarm includes: controlling the alarm indicator light to flash.

[0052] In some embodiments, the first set value is 85PPM, the second set value is 160PPM, and the preset time period is the previous week. The second water quality detection sensor is used to detect the TDS value of the purified water in the kettle every day. For example, the TDS value of the purified water last Monday was 162PPM, the TDS value of the purified water last Tuesday was 165PPM, the TDS value of the purified water last Wednesday was 168PPM, the TDS value of the purified water last Thursday was 172PPM, the TDS value of the purified water last Friday was 176PPM, the TDS value of the purified water last Saturday was 180PPM, and the TDS value of the purified water last Sunday was 185PPM. Since the TDS value of the purified water on each day of the previous week is greater than the second set value, it is determined that the water quality of the purified water on each day of the previous week is poor water quality. That is, the water quality of the purified water in the previous week meets the third preset condition, and the buzzer on the refrigerator is controlled to beep.

[0053] Furthermore, the refrigerator is provided with a display screen, and after obtaining the water quality of the external water, the method for purifying the water quality further includes: displaying the water quality of the external water using the display screen. In this way, the user can understand the water quality of the external water, thereby determining whether to use the second purification device to purify the external water, and further understanding the use of the second purification device.

[0054] Furthermore, after obtaining the water quality of the purified water, the method for purifying water quality also includes: displaying the water quality of the purified water using a display screen, so that the user can intuitively understand the water quality of the purified water, and thus determine whether the purified water meets the healthy drinking standard.

[0055] Furthermore, a secondary purification indicator light is provided on the display screen. After the first purification device and the second purification device are triggered to purify the external water, the method for purifying water quality further includes: triggering the secondary purification indicator light on the display screen to flash. In this way, by whether the secondary purification indicator light flashes, it can be understood whether the second purification device is used to purify the external water. This makes it easier for the user to understand the use of the second purification device more intuitively.

[0056] In some embodiments, in combination Figure 3 As shown, Figure 3Figure 1 is a schematic diagram of the structure of the display screen on the refrigerator. Figure 3 In the embodiment, the display screen 210 is provided with an external water quality indicator 211, an external water quality indicator 212, an external water quality indicator 213, an external water quality indicator 214, a purified water quality indicator 215, a purified water quality indicator 216, a secondary purification indicator 217 and a water intake switch button 218. The first water quality detection sensor sends the detected TDS value of the external water to the control board of the refrigerator. The control board obtains the water quality of the external water according to the TDS value of the external water. The second water quality detection sensor sends the detected TDS value of the purified water to the control board of the refrigerator. The control board obtains the water quality of the purified water according to the TDS value of the purified water. The control board controls the corresponding indicator lights on the display screen to flash according to the water quality of the external water or the purified water. To display the water quality of the external water, or to display the water quality of the purified water. For example: when the water quality of the external water is excellent, the main control board controls the external water quality indicator 211 to flash. When the water quality of the external water is good, the main control board controls the external water good quality indicator 212 to flash. When the water quality of the external water is poor, the main control board controls the external water poor quality indicator 213 to flash. When the water quality of the purified water is excellent, the main control board controls the purified water excellent quality indicator 214 to flash. When the water quality of the purified water is good, the main control board controls the purified water good quality indicator 215 to flash. When the water quality of the purified water is poor, the main control board controls the purified water poor quality indicator 216 to flash. When the second purification device purifies the external water, the main control board controls the secondary purification indicator 217 to flash. When the user wants to take water, the purified water in the kettle is obtained by clicking the water take switch button 218.

[0057] Further, after the first purification device and the second purification device are triggered to purify the external water, the method for purifying water quality also includes: obtaining the historical clean water volume of the second purification device, and obtaining the effective clean water volume of the second purification device. Calculate the ratio of the historical clean water volume to the effective clean water volume. Obtain the used time of the second purification device. Divide the used time by the ratio to obtain the target use time of the second purification device. Subtract the used time from the target use time to obtain the remaining use time of the second purification device. Among them, the effective clean water volume of the second purification device represents the amount of water that the second purification device can effectively purify. The used time of the second purification device is the time from the installation time of the second purification device to the current time. In this way, it is convenient for users to promptly understand the remaining service life of the second purification device.

[0058] In some embodiments, the historical water purification volume of the second purification device is 30 liters, the effective water purification volume of the second purification device is 5000 liters, and the second purification device has been used for 7 days. Then, the ratio of the historical water purification volume to the effective water purification volume is 0.006. After the used time is divided by the ratio, the target use time of the second purification device is 1167 days. Therefore, the remaining use time of the second purification device is 1160 days.

[0059] Furthermore, obtaining the historical purified water volume of the second purification device includes: accumulating and calculating the purified water volume purified each time by the second purification device within the historical time to obtain the historical purified water volume of the second purification device.

[0060] Furthermore, a water level sensor is provided in the kettle, and the amount of clean water purified by the second purification device each time is obtained in the following manner: the first water level and the second water level of the purified water are obtained by using the water level sensor. Among them, the first water level is the water level in the kettle before the second purification device purifies the external water, and the second water level is the water level in the kettle after the second purification device purifies the external water. The water level difference between the first water level and the second water level is obtained, and the bottom area of ​​the kettle is obtained. The amount of clean water of the second purification device is obtained by multiplying the water level difference by the bottom area of ​​the kettle. In this way, according to the first water level and the second water level, the water level change of the purified water in the kettle can be understood, so that the amount of external water flowing into the kettle can be calculated. Since the external water flowing into the kettle at this time is the external water purified by the second purification device, the amount of clean water of the second purification device can be accurately obtained according to the amount of external water flowing into the kettle.

[0061] Further, obtaining the effective clean water volume of the second purification device includes: detecting the material of the filter element in the second purification device. Using the material of the filter element, performing a table lookup operation in a preset data table to find out the alternative clean water volume corresponding to the material. Determining the alternative clean water volume as the effective clean water volume. The preset data table stores the corresponding relationship between the material and the alternative clean water volume.

[0062] Further, a stop valve is provided in the refrigerator, and the stop valve is provided on the water inlet pipe. The stop valve is used to control the flow rate of external water entering the water inlet pipe. Before obtaining the water quality of the external water, the method for purifying the water quality also includes: obtaining the third water level of the purified water by using a water level sensor. When the third water level is less than or equal to the first preset value, the stop valve is controlled to open so that the external water enters the water inlet pipe in the refrigerator. When the third water level is greater than or equal to the second preset value, the stop valve is controlled to close. Among them, the second preset value is greater than the first preset value. Since there is less purified water in the kettle, the daily use needs of the user cannot be met. Therefore, when the third water level of the purified water in the kettle is less than or equal to the first preset value, the stop valve is controlled to open so that the external water enters the water inlet pipe in the refrigerator for purification. When the third water level of the purified water in the kettle is greater than or equal to the second preset value, the stop valve is controlled to close so that the external water no longer enters the water inlet pipe in the refrigerator, and the purified water in the kettle can be kept sufficient. Thereby, the daily use needs of the user can be met.

[0063] In some embodiments, in combination Figure 4 As shown, Figure 4 Schematic diagram of the structure of refrigerator 2. Figure 4 In the embodiment, a stop valve 201 is provided on the water inlet pipe of the refrigerator 2, and the stop valve 201 is connected to the water inlet end of the first purification device 202, and the water outlet end of the first purification device 202 is connected to the selection valve 203. A first water quality detection sensor 207 is provided on the pipeline between the stop valve 201 and the first purification device 202. The first valve switch of the selection valve 203 is connected to the kettle 205 through the first pipeline. The second valve switch of the selection valve 203 is connected to the water inlet end of the second purification device 204 through the second pipeline, and the water outlet end of the second purification device 204 is connected to the kettle 205. Figure 5 As shown, Figure 5 Schematic diagram of the structure of refrigerator 2. Figure 5In the embodiment, the control board 206 of the refrigerator 2 is respectively connected to the first water quality detection sensor 207, the second water quality detection sensor 208, the water level sensor 209, the stop valve 201, the selection valve 203 and the display screen 210 for communication. The water level sensor 209 detects the third water level of the purified water in the kettle 205, and uploads the third water level to the main control board 206. When the third water level is less than or equal to the preset value, the main control board 206 controls the stop valve 201 to open, so that the external water enters the water inlet pipe. When the external water entering the water inlet pipe passes through the first water quality detection sensor 207, the first water quality detection sensor 207 detects the TDS value of the external water, and sends the TDS value of the external water to the main control board 206. The main control board 206 obtains the water quality of the external water according to the TDS value of the external water. The main control board 206 controls the display screen 210 to display the water quality of the external water. When the water quality of the external water meets the first preset condition, the main control board 206 controls the first purification device 202 to purify the external water, and controls the first valve switch of the selection valve 203 to open, so that the external water purified by the first purification device 202 flows into the kettle 205 through the first pipe for storage. When the water quality of the external water meets the second preset condition, the main control board 206 controls the first purification device 202 to purify the external water, and controls the second valve switch of the selection valve 203 to open, so that the external water purified by the first purification device 202 flows into the second purification device 204 through the second pipe, and the external water is purified by the second purification device 204 for the second time, and then flows into the kettle 205 for storage. The second water quality detection sensor 208 in the kettle detects the TDS value of the purified water, and uploads the TDS value of the purified water to the main control board 206. The main control board 206 obtains the water quality of the purified water according to the TDS value of the purified water. The main control board 206 controls the display screen 210 to display the water quality of the purified water.

[0064] Optionally, a drain pipe is provided in the refrigerator, and the drain pipe is used to discharge the purified water in the kettle. After obtaining the water quality of the purified water at a preset time interval, the method for purifying the water quality also includes: when the water quality of the purified water meets the third preset condition within the preset time period, the stop valve is controlled to be closed, and the purified water in the kettle is discharged through the drain pipe. Since the kettle is arranged inside the refrigerator, if the water in the kettle is of poor quality for a period of time, the water in the kettle is prone to produce air pollutants, which is easy to pollute the other internal environment of the refrigerator. Therefore, when the water quality of the purified water within the preset time period is poor, closing the stop valve can prevent external water from entering the refrigerator and flowing into the kettle. At the same time, the purified water in the kettle is discharged through the drain pipe, so that the kettle no longer continues to store water that is prone to air pollution. It can prevent water that is prone to air pollution from being retained in the kettle and continuously producing air pollutants, thereby reducing the pollution to other internal environments of the refrigerator. And then the safety of the internal environment of the refrigerator can be improved.

[0065] Combination Figure 6 As shown, the embodiment of the present disclosure provides a device 1 for purifying water quality, including a processor (processor) 11 and a memory (memory) 12. Optionally, the device may also include a communication interface (CommunicationInterface) 13 and a bus 14. Among them, the processor 11, the communication interface 13, and the memory 12 can communicate with each other through the bus 14. The communication interface 13 can be used for information transmission. The processor 11 can call the logic instructions in the memory 12 to execute the method for purifying water quality of the above embodiment.

[0066] In addition, the logic instructions in the memory 12 can be implemented in the form of software functional units and can be stored in a computer-readable storage medium when sold or used as an independent product.
