DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The water purifier control method provided in the embodiment of the present invention can be applied in Figure 1 In the application environment shown. Figure 1 As shown, the water purifier 100 includes a flow sensor 10 , a pressure sensor 11 , a water storage container 12 , a water inlet solenoid valve 13 , a booster pump 14 and a filtering system 15 .

[0028] Among them, one end of the water inlet solenoid valve 13 is connected to the tap water inlet 00, the other end of the water inlet solenoid valve 13 is connected to one end of the boosting pump 14, the water inlet end of the filtration system 15 is connected to the other end of the boosting pump 14, the clean water discharge end of the filtration system 15 is connected to the water storage container 12, and the concentrated water discharge end of the filtration system 15 is connected to the tap water discharge pipeline 01. The flow sensor 10 is arranged on the tap water discharge pipeline 01, which is used to detect the water flow signal of the tap water discharge pipeline 01, and the pressure sensor 11 is used to detect the water pressure of the pipeline 02 where the water storage container 12 is located.

[0029] The water inlet solenoid valve 13 is a solenoid valve used to control the flow of tap water flowing out of the tap water inlet 00 to the booster pump 14 .

[0030] The booster pump 14 is used to boost the pressure of the tap water passing through the water inlet solenoid valve 13 .

[0031] The filter system 15 is used to filter the tap water pressurized by the booster pump 14 to prepare pure water. In the process of preparing pure water, concentrated water is produced, and the concentrated water can be introduced into the tap water discharge pipeline 01 through the concentrated water discharge end of the filter system 15, mixed with the tap water in the tap water discharge pipeline 01, and discharged through the tap water faucet at the end of the tap water discharge pipeline 01. Optionally, the filter system 15 uses a reverse osmosis filter element membrane for filtering.

[0032] The tap water discharge pipeline 01 can be a pipeline or a water pipe. The pipeline 02 where the water storage container 12 is located can be a pipeline or a water pipe.

[0033] See also Figure 2 As shown, Figure 2 A flow chart of a water purifier control method provided by an embodiment of the present invention. The method can be applied to Figure 1 In the application environment shown. The water purifier control method includes the following steps S100:

[0034] S100: When the water flow signal of the tap water discharge pipeline 01 is detected, and it is detected that the water pressure of the pipeline 02 where the water storage container 12 is located is less than the first set value, the water inlet solenoid valve 13 is controlled to open, the booster pump 14 is started, and the filter system 15 is started, so that the filter system 15 prepares pure water from the tap water pressurized by the booster pump 14, wherein the pure water is collected into the water storage container 12, and the concentrated water generated by the filter system 15 when preparing the pure water is mixed with the tap water in the tap water discharge pipeline 01 to be discharged through the tap at the end of the tap water discharge pipeline 01, and the water pressure of the concentrated water is higher than the water pressure of the tap water in the tap water discharge pipeline 01.

[0035] Among them, the first set value is used to determine whether the pure water in the water storage container meets the conditions for discharge. If the water pressure of the pipeline where the storage container is located is detected to be less than the first set value, it means that there is no pure water or the pure water content is small in the storage container at this time, that is, the pure water in the water storage container does not meet the conditions for discharge, so pure water cannot be supplied to the outside; if the water pressure of the pipeline where the water storage container is located is detected to be greater than or equal to the first set value, it means that the pure water content in the storage container is large, that is, the pure water in the water storage container meets the conditions for discharge, so pure water can be supplied to the outside. The first set value is set according to the actual scenario and is not specifically limited here.

[0036] In this embodiment, when a water flow signal of tap water is detected and it is detected that the water pressure of the pipeline 02 where the water storage container 12 is located is less than a first set value, the water inlet solenoid valve 13 is controlled to open, the booster pump 14 is started, and the filtration system 15 is started, so that the filtration system 15 prepares the pure water and the pure water is merged into the water storage container 12, and the water pressure of the concentrated water generated by the filtration system 15 is higher than the water pressure of the tap water, so that the concentrated water passes through the concentrated water discharge end of the filtration system 15 and is merged into the tap water discharge pipeline 01, mixed with the tap water and discharged through the tap at the end of the tap water discharge pipeline 01. In the present application, when the water flow signal of tap water is detected, it means that the tap at the end of the tap water discharge pipeline 01 is turned on, and the water pressure of the pipeline 02 where the water storage container 12 is located is less than the first preset value, which means that the pure water in the water storage container does not meet the conditions for discharge to the outside. The water storage container 12 can also store the pure water prepared by the filtration system 15. Based on this, the water inlet solenoid valve 13 is controlled to open, the booster pump 14 is started, and the filtration system 15 is started, so that the filtration system 15 prepares the pure water and collects the pure water. The concentrated water is discharged into the water storage container 12, and the water pressure of the concentrated water generated by the filtration system 15 when preparing pure water is higher than the water pressure of the tap water, so that the concentrated water passes through the concentrated water discharge end of the filtration system 15 and is merged into the tap water discharge pipe 01, and is mixed with the tap water to be discharged through the tap at the end of the tap water discharge pipe 01. At this time, the mixed water discharged from the tap can be used in non-drinking scenarios, and the concentrated water is avoided from being directly discharged into the sewer, thereby greatly reducing the discharge of concentrated water, improving the utilization rate of concentrated water, and reducing the waste of water resources.

[0037] In some optional implementations of this embodiment, the water purifier control method further includes the following step S200:

[0038] S200: During the process of the filtration system 15 preparing pure water from the tap water pressurized by the booster pump 14, if the water flow signal of the tap water discharge pipeline 01 disappears, the water inlet solenoid valve 13, the booster pump 14 and the filtration system 15 are controlled to be closed, so that the filtration system 15 stops preparing the pure water.

[0039] In this embodiment, during the process of preparing pure water by the tap water pressurized by the booster pump 14, if it is detected that the water flow signal of the tap water discharge pipe 01 disappears, that is, the flow sensor 10 does not detect the water flow signal of the tap water discharge pipe 01, it means that the tap is not turned on or there is no water flowing out of the tap water inlet 00. Then, the water inlet solenoid valve 13, the booster pump 14 and the filter system 15 are promptly controlled to be closed, so that the filter system 15 stops preparing pure water, avoids the filter system 15 from continuing to work in the absence of water, shortens the service life of the filter system 15, and thus improves the reliability, service life and intelligence of the water purifier.

[0040] In some optional implementations of this embodiment, the control method further includes the following step S300:

[0041] S300: During the process of the filtration system 15 preparing pure water from the tap water pressurized by the booster pump 14, if it is detected that the water pressure in the pipeline 02 where the water storage container 12 is located is greater than a second set value, the water inlet solenoid valve 13, the booster pump 14 and the filtration system 15 are controlled to be closed, so that the filtration system 15 stops preparing the pure water.

[0042] The second set value is used to determine whether the storage space of the pure water in the water storage container is full. If the water pressure in the pipeline where the storage container is located is detected to be greater than the second set value, it means that the storage space in the storage container is full. The second set value is set according to the actual scenario and is not specifically limited here.

[0043] The second setting value is greater than the first setting value.

[0044] In this embodiment, during the process of preparing pure water by the filter system 15 using tap water pressurized by the booster pump 14, if it is detected that the water pressure in the pipeline 02 where the water storage container 12 is located is greater than the second set value, it means that the storage space for pure water in the water storage container 12 has reached the upper limit value. At this time, the water inlet solenoid valve 13, the booster pump 14 and the filter system 15 are controlled to be closed, so that the filter system 15 stops preparing pure water, prevents the pure water from overflowing from the water storage container 12, and prevents the water storage container 12 from being damaged.

[0045] Optionally, the water storage container 12 may be a pressure tank or a pressure water storage barrel.

[0046] In this embodiment, the purified water of the filtration system 15 can be stored in the water storage container 12 in advance, so that the water purifier does not need to be started frequently, and the frequency of starting the filtration system 15 is reduced, thereby extending the service life of the filtration system 15.

[0047] Figure 3A schematic diagram of an application environment of a water purifier control method in another embodiment is provided. Figure 3 As shown, the water purifier further includes a purified water outlet faucet 16 , and the purified water outlet faucet is connected to the water storage container 12 .

[0048] The water purifier control method provided in the embodiment of the present invention can be applied in Figure 3 In some optional implementations of this embodiment, the water purifier control method further includes the following step S400:

[0049] S400, when the opening signal of the pure water outlet faucet 16 is detected, and when it is detected that the water pressure of the pipeline 02 where the water storage container 12 is located is greater than or equal to the first set value, the pure water is controlled to flow out from the water storage container 12 to the pure water outlet faucet 16.

[0050] In this embodiment, when the opening signal of the pure water outlet faucet 16 is detected, and it is detected that the water pressure of the pipeline 02 where the water storage container 12 is located is greater than or equal to the first set value, it means that the pure water outlet faucet 16 is opened and the pure water stored in the storage space of pure water in the water storage container reaches the discharge condition. Therefore, the pure water is controlled to be discharged from the water storage container 12 to the pure water outlet faucet 16, so as to improve the intelligence level of the water purifier. In this way, the filter system 15 does not need to be started frequently, the frequency of starting the filter system 15 is reduced, and the service life of the filter system 15 is extended.

[0051] In some optional implementations of this embodiment, the water purifier control method further includes the following step S500:

[0052] S500: When the opening signal of the pure water outlet faucet 16 is detected, the water flow signal of the tap water discharge pipeline 01 is detected, and the water pressure of the pipeline 02 where the water storage container 12 is located is detected to be less than the first set value, the water inlet solenoid valve 13 is controlled to open, the booster pump 14 is started, and the filtration system 15 is started, so that at least a part of the pure water prepared by the filtration system 15 is discharged through the pure water outlet faucet 16.

[0053] In this embodiment, when the opening signal of the pure water outlet tap 16 is detected, the water flow signal of the tap water discharge pipeline 01 is detected, and the water pressure of the pipeline 02 where the water storage container 12 is located is detected to be less than the first set value, it means that the pure water outlet tap 16 is turned on, the tap water tap is turned on, and the storage space of the pure water in the water storage container 12 is less than the lower limit of the water storage, that is, at this time, there is no pure water stored in the water storage container 12 or the storage amount of pure water is small, that is, the pure water in the water storage container does not meet the conditions for discharge to the outside, so pure water cannot be supplied to the outside, then the water inlet solenoid valve 13 is controlled to be turned on, the booster pump 14 is turned on, and the filter system 15 is turned on, so that the filter system 15 prepares pure water. Optionally, part of the pure water can be discharged to the pure water outlet tap 16 through the water storage container 12, and the other part of the pure water can be stored in the water storage container to improve the intelligence of the water purifier, so that the filter system 15 does not need to be frequently started, and the frequency of starting the filter system 15 is reduced, thereby extending the service life of the filter system 15. At the same time, the concentrated water generated in the process of preparing pure water by the filtration system is collected into the tap water discharge pipe 01 through the concentrated water discharge end of the filtration system 15, mixed with tap water and discharged through the tap at the end of the tap water discharge pipe 01. At this time, the mixed water discharged from the tap can be used in non-drinking scenarios, and the concentrated water is avoided from being discharged directly into the sewer. ， This can significantly reduce the discharge of concentrated water, improve the utilization rate of concentrated water, and reduce the waste of water resources.

[0054] Figure 4 A schematic diagram of an application environment of a water purifier control method in another embodiment is provided. Figure 4 As shown, the water purifier also includes a concentrated water solenoid valve 17, a concentrated water outlet pipe 03 and a concentrated water discharge pipe 04, one end of the concentrated water outlet pipe 03 is connected to the concentrated water discharge end of the filtration system 15, and the other end of the concentrated water outlet pipe 03 is connected to the tap water discharge pipe 01, the concentrated water solenoid valve 17 is arranged on the concentrated water discharge pipe 04, one end of the concentrated water discharge pipe 04 is connected to the concentrated water outlet pipe 03, and the other end of the concentrated water discharge pipe 04 is connected to the concentrated water drain outlet 18.

[0055] The concentrated water solenoid valve 17 may be a solenoid valve for controlling whether the concentrated water is discharged to the concentrated water outlet 18. The concentrated water outlet pipeline 03 may be a pipeline or a water pipe. The concentrated water discharge pipeline 04 may be a pipeline or a water pipe.

[0056] Optionally, a pressure water storage barrel or a pressure water storage tank can be set on the concentrated water discharge pipeline 04 to store concentrated water. When concentrated water is needed, the concentrated water solenoid valve 17 is controlled to open so that the concentrated water is discharged from the pressure water storage barrel or the pressure water storage tank to the concentrated water drain port 18.

[0057] Among them, the concentrated water outlet 18 can be connected to the flower watering pipe or the toilet pipe, so that the concentrated water can be used for watering flowers or flushing toilets, thereby improving the utilization rate of concentrated water and reducing the waste of water resources.

[0058] The water purifier control method provided in the embodiment of the present invention can be applied in Figure 4 In some optional implementations of this embodiment, the water purifier control method further includes S600:

[0059] S600: During the process of the filtration system 15 preparing pure water from the tap water pressurized by the booster pump 14, if the water flow signal of the tap water discharge pipeline 01 is not detected, the concentrated water solenoid valve 17 is controlled to open so that the concentrated water flows to the concentrated water discharge outlet 18.

[0060] The concentrated water outlet 18 is used to discharge concentrated water to non-drinking scenarios (such as watering flowers, flushing toilets, etc.).

[0061] In this embodiment, during the process of the filtration system preparing pure water from the tap water pressurized by the booster pump, if the water flow signal of the tap water discharge pipeline is not detected, it means that the tap is closed. At this time, the tap water flowing out of the tap water inlet 00 flows to the water inlet solenoid valve 13, and the concentrated water solenoid valve 17 is controlled to open so that the concentrated water flows to the concentrated water discharge outlet 18, thereby improving the intelligence level of the water purifier, and the concentrated water can be used for non-drinking scenarios such as watering flowers and flushing toilets, thereby improving the utilization rate of concentrated water and reducing the waste of water resources.

[0062] Figure 5 A schematic diagram of an application environment of a water purifier control method in another embodiment is provided. Figure 5 As shown, the water purifier also includes a heater 19, a clean water outlet solenoid valve 20 and a pure water outlet pipeline. The heater 19 is arranged on the pure water outlet pipeline, one end of the pure water outlet pipeline is connected to the water storage container 12, the other end of the pure water outlet pipeline is connected to one end of the clean water outlet solenoid valve 20, and the other end of the clean water outlet solenoid valve 20 is connected to the pure water outlet faucet.

[0063] The heater 19 is used to heat the purified water flowing to the purified water outlet tap 16. The purified water outlet pipeline can be an extension pipeline of the pipeline 02 where the storage device is located, which can be a pipe or a water pipe.

[0064] The purified water outlet solenoid valve 20 may be a solenoid valve, which is used to control the purified water heated by the heater 19 to flow to the purified water outlet faucet 16 .

[0065] The water purifier control method provided in the embodiment of the present invention can be applied in Figure 5 In some optional implementations of this embodiment, the water purifier control method further includes the following step S700:

[0066] S700: When the opening signal of the pure water outlet faucet 16 is detected, the heater 19 is controlled to heat the pure water flowing to the pure water outlet faucet 16 until the preset temperature is reached, and the pure water outlet solenoid valve is controlled to open so that the temperature of the pure water flowing out of the pure water outlet faucet reaches the preset temperature.

[0067] Optionally, during the process of preparing pure water by the filtration system 15, when an opening signal of the pure water outlet faucet 16 is detected, the heater 19 is controlled to heat the pure water flowing to the pure water outlet faucet 16 until a preset temperature is reached, and the pure water outlet solenoid valve is controlled to open so that the temperature of the pure water flowing out of the pure water outlet faucet reaches the preset temperature.

[0068] The preset temperature can be determined according to the actual application scenario and is not specifically limited here.

[0069] In this embodiment, the purified water is heated by the heater 19 so that the temperature of the purified water flowing out of the purified water outlet faucet 16 reaches the preset temperature, so that the user can adjust the water temperature of the purified water according to his or her own needs, thereby improving the user experience and the intelligence level of the water purifier.

[0070] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

The flow sensor 10 is arranged on the tap water discharge pipeline 01 to detect the water flow signal of the tap water discharge pipeline 01. The pressure sensor 11 is used to detect the water pressure of the pipeline 02 where the water storage container 12 is located. The control device based on a water purifier corresponds one-to-one with the control method based on a water purifier in the above-mentioned embodiment. Please refer to Figure 6 As shown, the water purifier control device includes a signal detection module 30, and the functional module is described in detail as follows:

[0072] The signal detection module 30 is used to control the water inlet solenoid valve 13 to open, the booster pump 14 to start, and the filter system 15 to start when the water flow signal of the tap water discharge pipeline is detected and the water pressure of the pipeline 02 where the water storage container is located is less than a first set value, so that the filter system 15 prepares pure water from the tap water pressurized by the booster pump 14, wherein the pure water is collected into the water storage container 12, and the concentrated water generated by the filter system 15 when preparing the pure water is mixed with the tap water in the tap water discharge pipeline 01 to be discharged through the tap at the end of the tap water discharge pipeline 01, and the water pressure of the concentrated water is higher than the water pressure of the tap water in the tap water discharge pipeline 01.

At this time, the mixed water discharged from the tap can be used in non-drinking scenarios, and the concentrated water is avoided from being directly discharged into the sewer, thereby greatly reducing the discharge of concentrated water, improving the utilization rate of concentrated water, and reducing the waste of water resources.
