Description

Technical Field

[0001] This invention relates to the field of water purifier technology, and in particular to a water purifier flushing method, apparatus, water purifier, and storage medium. Background Technology

[0002] In recent years, water purifiers have received increasing attention from consumers as a health product, and the water purification industry has also developed rapidly as a result.

[0003] Reverse osmosis water purifiers are the mainstream household water purifiers in China. In order to ensure the service life of the reverse osmosis filter element, the surface of the reverse osmosis filter membrane must be continuously rinsed during use to reduce the salt concentration on the surface of the reverse osmosis filter membrane, slow down the clogging caused by scale buildup on the membrane surface, and ensure a certain proportion of concentrated water (commonly known as wastewater) is discharged. However, currently, tap water is used to rinse the filter element of water purifiers. Tap water itself contains impurities, resulting in poor rinsing effect. Summary of the Invention

[0004] Based on this, it is necessary to address the technical problem of poor rinsing effect of existing water purifier filter cartridges by proposing a water purifier rinsing method, device, water purifier, and storage medium.

[0005] In a first aspect, a water purifier flushing method is provided. The method is applied to a water purifier comprising an inlet solenoid valve, a booster pump, a filtration system, a first check valve, a flushing solenoid valve, a second check valve, a first pressure sensor, a purified water storage container, and a purified water discharge pipe. One end of the inlet solenoid valve is connected to a tap water inlet, and the other end is connected to one end of the booster pump. The inlet end of the filtration system is connected to the other end of the booster pump, and the purified water discharge end of the filtration system is connected to the first end of the first check valve. One end of the flushing solenoid valve is connected to the second end of the first check valve, and the other end is connected to the first end of the second check valve. The second end of the second check valve is connected to one end of the booster pump. The purified water discharge pipe is connected to the second end of the first check valve, and the purified water discharge pipe is equipped with the first pressure sensor and the purified water storage container. The first pressure sensor is used to detect the water pressure in the purified water discharge pipe.

[0006] The water purifier rinsing method includes:

[0007] Obtain the first flushing signal;

[0008] In response to the first flushing signal, determine whether the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure;

[0009] If the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, the inlet solenoid valve is closed, the booster pump is turned on, and the filtration system is turned on. The filtration system is then controlled to process the remaining tap water from the booster pump and the filtration system into purified water, and a ready signal is obtained.

[0010] In response to the ready signal, the flushing solenoid valve is opened, the booster pump is pressurized, and the filter system is flushed. The pure water in the pure water discharge pipe and the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve to flush the filter element of the filter system.

[0011] Secondly, a water purifier flushing device is provided. The device is applied to a water purifier, which includes an inlet solenoid valve, a booster pump, a filtration system, a first check valve, a flushing solenoid valve, a second check valve, a first pressure sensor, a purified water storage container, and a purified water discharge pipe. One end of the inlet solenoid valve is connected to a tap water inlet, and the other end is connected to one end of the booster pump. The inlet end of the filtration system is connected to the other end of the booster pump, and the purified water discharge end of the filtration system is connected to the first end of the first check valve. One end of the flushing solenoid valve is connected to the second end of the first check valve, and the other end is connected to the first end of the second check valve. The second end of the second check valve is connected to one end of the booster pump. The purified water discharge pipe is connected to the second end of the first check valve, and the purified water discharge pipe is equipped with the first pressure sensor and the purified water storage container. The first pressure sensor is used to detect the water pressure in the purified water discharge pipe.

[0012] The water purifier flushing device includes:

[0013] The acquisition module is used to acquire the first flushing signal;

[0014] The first response module is used to respond to the first flushing signal and determine whether the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure.

[0015] The control module is used to control the inlet solenoid valve to close, the booster pump to open, and the filtration system to open if the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure. The control module controls the filtration system to process the tap water remaining in the booster pump and the filtration system into pure water and obtains a ready signal.

[0016] The second response module is used to respond to the ready signal, control the flushing solenoid valve to open, the booster pump to pressurize, and the filtration system to flush the filter element. The pure water in the pure water discharge pipe and the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve to flush the filter element of the filtration system.

[0017] Thirdly, a water purifier includes a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that it further includes: an inlet solenoid valve, a booster pump, a filtration system, a first check valve, a flushing solenoid valve, a second check valve, a first pressure sensor, a purified water storage container, and a purified water discharge pipe; one end of the inlet solenoid valve is connected to a tap water inlet, and the other end of the inlet solenoid valve is connected to one end of the booster pump; the inlet end of the filtration system is connected to the other end of the booster pump, the purified water discharge end of the filtration system is connected to the first end of the first check valve, one end of the flushing solenoid valve is connected to the second end of the first check valve, the other end of the flushing solenoid valve is connected to the first end of the second check valve, and the second end of the second check valve is connected to one end of the booster pump; the purified water discharge pipe is connected to the second end of the first check valve, and the purified water discharge pipe is equipped with the first pressure sensor and the purified water storage container; the first pressure sensor is used to detect the water pressure in the purified water discharge pipe.

[0018] When the processor executes the computer program, it implements the steps of the above-described water purifier flushing method.

[0019] Fourthly, a computer-readable storage medium is provided, the computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the above-described water purifier flushing method.

[0020] The water purifier flushing method proposed in this invention obtains a first flushing signal, then responds to the first flushing signal by determining whether the water pressure in the purified water discharge pipe is greater than or equal to a preset water pressure. If the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, the inlet solenoid valve is closed, the booster pump is turned on, and the filtration system is turned on. The filtration system is then controlled to process the remaining tap water from the booster pump and the filtration system into purified water, generating a ready signal. Finally, in response to the ready signal, the flushing solenoid valve is opened, the booster pump pressurizes the water, and the filtration system flushes the filter element. In this system, the purified water in the purified water discharge pipe and the purified water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve to flush the filter element of the filtration system. When the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, the filter element can be flushed with purified water. The purified water meets the water output requirements of the water purifier. Using purified water to flush the filter element can improve the flushing effect and greatly extend the service life of the filter element. In addition, compared with flushing the filter element with tap water, using purified water to flush the filter element can achieve a better flushing effect with less purified water, thereby saving water resources.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The water purifier flushing method provided in this embodiment of the invention can be applied to, for example... Figure 1 The application environment shown. For example... Figure 1 As shown, the water purifier 100 includes an inlet solenoid valve 01, a booster pump 02, a filtration system 03, a first check valve 04, a flushing solenoid valve 05, a second check valve 06, a first pressure sensor 07, a purified water storage container 08, and a purified water discharge pipe 10. One end of the inlet solenoid valve 01 is connected to the tap water inlet 00, and the other end of the inlet solenoid valve 01 is connected to one end of the booster pump 02. The inlet end of the filtration system 03 is connected to the other end of the booster pump 02, and the purified water discharge end of the filtration system 03 is connected to the first end a of the first check valve 04. The flushing solenoid valve 05... One end of the flushing solenoid valve 05 is connected to the second end b of the first one-way valve 04, and the other end of the flushing solenoid valve 05 is connected to the first end c of the second one-way valve 06. The second end d of the second one-way valve 06 is connected to one end of the booster pump 02. The pure water discharge pipe 09 is connected to the second end b of the first one-way valve 04. The pure water discharge pipe 09 is equipped with the first pressure sensor 07 and the pure water storage container 08. The first pressure sensor 07 is used to detect the water pressure of the pure water discharge pipe 09. The outlet of the pure water discharge pipe 09 is connected to the pure water faucet 10.

[0031] Among them, the inlet solenoid valve 01 is a solenoid valve used to control the flow of tap water from the tap water inlet 00 to the booster pump 02. The flushing solenoid valve 05 is a solenoid valve. The booster pump 02 is used to pressurize the tap water or purified water passing through the booster pump 02. The filtration system 03 is used to filter the tap water pressurized by the booster pump 02 to prepare purified water and produce concentrated water, and can also flush the filter element of the purified water pressurized by the booster pump 02. The first one-way valve 04 and the second one-way valve 06 are both one-way valves, the first pressure sensor 07 is a pressure sensor, and the purified water discharge pipe 10 can be a pipe or a water pipe.

[0032] Optionally, the filter element of filtration system 03 is a filter element using a reverse osmosis filter membrane.

[0033] Please see Figure 2 As shown, Figure 2This is a schematic flowchart of a water purifier rinsing method according to an embodiment of the present invention. The method is applied to a water purifier and includes the following steps:

[0034] S101: Obtain the first flushing signal;

[0035] The first flushing signal is a flushing signal. For example, the user obtains the first flushing signal by triggering the flushing function button on the water purifier.

[0036] Optionally, the first flushing signal is actively triggered by the program file of this application according to preset conditions. For example, the preset condition is that if the filtration time exceeds 10 hours, a flushing signal is actively triggered, and this flushing signal is used as the first flushing signal.

[0037] S102: In response to the first flushing signal, determine whether the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure;

[0038] In this embodiment, after obtaining the first flushing signal, the system responds to the first signal to determine whether the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure. It should be noted that the higher the water pressure in the pure water discharge pipe, the more water is stored in the pure water storage container.

[0039] As an example, when the purified water storage container is full of water, the water pressure in the purified water discharge pipe is detected to obtain the maximum water pressure, which is then used as the preset water pressure.

[0040] S103: If the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure, control the inlet solenoid valve to close, the booster pump to open, and the filtration system to open. Control the filtration system to process the tap water remaining in the booster pump and the filtration system into pure water, and obtain a ready signal.

[0041] In one implementation, when the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, it is determined whether the inlet solenoid valve is closed. If it is not closed, the inlet solenoid valve is controlled to close. It is also determined whether the booster pump is turned on. If it is not turned on, the booster pump is controlled to turn on. Finally, it is determined whether the filtration system is turned on. If it is not turned on, the filtration system is controlled to turn on.

[0042] Once the filtration system is confirmed to be open, the system controls the booster pump and the remaining tap water in the filtration system to produce purified water, thus generating a ready signal.

[0043] S104: In response to the ready signal, control the flushing solenoid valve to open, the booster pump to pressurize, and the filtration system to flush the filter element. The pure water in the pure water discharge pipe and the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve to flush the filter element of the filtration system.

[0044] In one implementation, when a ready signal is detected, the system responds to the ready signal by controlling the flushing solenoid valve to open, allowing the pure water from the pure water discharge pipe and the pure water storage container to enter one end of the booster pump through the flushing solenoid valve and the second one-way valve. The booster pump then pumps the pressurized pure water from the other end into the filtration system, and the filtration system uses the pure water from the pure water discharge pipe and the pure water storage container to flush the filter element.

[0045] The water purifier flushing method proposed in this embodiment obtains a first flushing signal, then responds to the first flushing signal by determining whether the water pressure in the purified water discharge pipe is greater than or equal to a preset water pressure. If the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, the inlet solenoid valve is closed, the booster pump is turned on, and the filtration system is turned on. The filtration system is then controlled to process the remaining tap water from the booster pump and the filtration system into purified water, generating a ready signal. Finally, in response to the ready signal, the flushing solenoid valve is opened, the booster pump pressurizes the water, and the filtration system flushes the filter element. In this system, the purified water in the purified water discharge pipe and the purified water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve to flush the filter element of the filtration system. When the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, the filter element can be flushed with purified water. The purified water meets the water output requirements of the water purifier. Using purified water to flush the filter element can improve the flushing effect and greatly extend the service life of the filter element. In addition, compared with flushing the filter element with tap water, using purified water to flush the filter element can achieve a better flushing effect with less purified water, thereby saving water resources.

[0046] In one embodiment, the step of determining whether the water pressure in the purified water discharge pipe is greater than or equal to a preset water pressure includes:

[0047] S201: Determine whether the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure;

[0048] S202: When the water pressure in the pure water discharge pipe is less than the preset water pressure, the inlet solenoid valve is opened, the booster pump is started, and the filtration system is started. The filtration system prepares pure water from the tap water that has been boosted by the booster pump. The pure water discharged from the pure water discharge end is stored in the pure water storage container through the first one-way valve.

[0049] S203: Jump to the step of determining whether the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure and continue execution until the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure.

[0050] In this embodiment, firstly, it is determined whether the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure. If the water pressure in the purified water discharge pipe is less than the preset water pressure, the inlet solenoid valve is opened, the booster pump is started, and the filtration system is started. The filtration system prepares purified water from the tap water boosted by the booster pump, and the purified water discharged from the purified water discharge end is stored in the purified water storage container through the first one-way valve.

[0051] Next, the process jumps to the step of determining whether the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure and continues to produce pure water until the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure. When the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure, it means that the pure water stored in the pure water storage container has met the requirements.

[0052] The water purifier flushing method proposed in this embodiment determines whether the water pressure in the purified water discharge pipe is greater than or equal to a preset water pressure. If the water pressure in the purified water discharge pipe is less than the preset water pressure, the inlet solenoid valve is opened, the booster pump is started, and the filtration system is activated. The filtration system prepares purified water from the tap water pressurized by the booster pump. The purified water discharged from the purified water discharge end is stored in the purified water storage container through the first one-way valve. Then, the process returns to the step of determining whether the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, continuing until the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure. This method can continuously prepare purified water even when the water pressure in the purified water discharge pipe is less than the preset water pressure. Then, when the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, the filter element is flushed with purified water, improving the flushing effect and significantly extending the filter element's lifespan. Furthermore, compared to flushing the filter element with tap water, flushing the filter element with purified water achieves a better flushing effect with less purified water, thus saving water resources.

[0053] In one embodiment, such as Figure 3As shown, the water purifier also includes a concentrated water storage container 11 and a concentrated water drain pipe 12. The concentrated water discharge end of the filtration system is connected to one end of the concentrated water drain pipe 12, and the concentrated water storage container 11 is provided on the concentrated water drain pipe 12.

[0054] The step of responding to the ready signal by controlling the flushing solenoid valve to open, the booster pump to pressurize, and the filtration system to flush the filter element includes:

[0055] S301: In response to the ready signal, control the flushing solenoid valve to open, the booster pump to pressurize, and the filtration system to flush the filter element, so that the concentrated water generated by the filtration system corresponding to the ready signal is discharged to the concentrated water storage container through the concentrated water discharge end and the concentrated water drainage pipe.

[0056] S302: Obtain the rinsing time of the filtration system and determine whether the rinsing time is greater than the preset rinsing time;

[0057] S303: If the rinsing time is longer than the preset rinsing time, then control the rinsing solenoid valve to close.

[0058] In this embodiment, in response to the ready signal, the flushing solenoid valve is opened, the booster pump pressurizes the water, and the filtration system flushes the filter element. This allows the concentrated water generated by the filtration system, corresponding to the ready signal, to be discharged through the concentrated water discharge end and the concentrated water drain pipe into the concentrated water storage container, thereby achieving the collection of concentrated water. If the concentrated water storage container is full, it can be discharged uniformly. As an example, when the concentrated water discharge button is triggered, the concentrated water in the concentrated water storage container is discharged from the concentrated water drain pipe.

[0059] Next, the flushing time of the filtration system is obtained, and it is determined whether the flushing time is greater than the preset flushing time. The preset flushing time can be a factory setting based on human experience or a user-defined setting. If the flushing time is greater than the preset flushing time, it means that the water purifier has flushed the filter cartridge for the preset time, so the flushing solenoid valve is closed to stop flushing the filter cartridge.

[0060] The water purifier flushing method proposed in this embodiment controls the opening of the flushing solenoid valve, the pressurization of the booster pump, and the flushing of the filter element in response to the ready signal. This allows the concentrated water generated by the filtration system corresponding to the ready signal to be discharged into the concentrated water storage container through the concentrated water discharge end and the concentrated water drain pipe. Next, the flushing time of the filtration system is acquired, and it is determined whether the flushing time is greater than a preset flushing time. If the flushing time is greater than the preset flushing time, the flushing solenoid valve is closed, allowing the concentrated water generated during filter element flushing to be collected in the concentrated water storage container for subsequent unified discharge. Furthermore, flushing stops when the preset flushing time is reached, improving the automation level of the water purifier flushing and enhancing the user experience.

[0061] In one embodiment, acquiring the first flushing signal includes:

[0062] S401: Obtain a water production signal and respond to the water production signal to obtain the generation time of the target flushing signal, wherein the target flushing signal is the second flushing signal with the latest generation time among all the second flushing signals, and the generation time of the second flushing signal is earlier than the generation time of the first flushing signal;

[0063] S402: Calculate the interval duration based on the generation time of the water production signal and the generation time of the target flushing signal, and determine whether the interval duration is greater than or equal to the preset duration.

[0064] S403: If the interval duration is greater than or equal to the preset duration, then the first flushing signal is generated.

[0065] In this embodiment, a water production signal is first acquired, which can be obtained by the user triggering a water production button. In response to the water production signal, the generation time of the target flushing signal is acquired. The generation time refers to the time when the target flushing signal is generated. The target flushing signal is the second flushing signal with the latest generation time among all the second flushing signals. The second flushing signal's generation time is earlier than the first flushing signal's generation time, and the second flushing signal is a flushing signal generated in the past. In short, the target flushing signal is the flushing signal with the latest generation time among all the second flushing signals preceding the first flushing signal.

[0066] Next, the interval duration is calculated based on the generation time of the water production signal and the generation time of the target flushing signal. As an example, the generation time of the water production signal is subtracted from the generation time of the target flushing signal to obtain the interval duration. Then, it is determined whether the interval duration is greater than or equal to a preset duration, which can be either user-defined or factory-set.

[0067] When the interval is longer than or equal to the preset time, it means that the filter cartridge of the water purifier has not been cleaned for a long time and may have become dirty. Therefore, the first flushing signal is generated to make the filtration system flush the filter cartridge, thereby improving the purity of the purified water.

[0068] The water purifier flushing method proposed in this embodiment acquires a water production signal and, in response to the water production signal, obtains the generation time of a target flushing signal. The target flushing signal is the second flushing signal with the latest generation time among all second flushing signals, and the generation time of the second flushing signal is earlier than the generation time of the first flushing signal. Then, based on the generation time of the water production signal and the generation time of the target flushing signal, an interval duration is calculated, and it is determined whether the interval duration is greater than or equal to a preset duration. If the interval duration is greater than or equal to the preset duration, the first flushing signal is generated. This method allows for the determination of whether the water purifier has not been flushed for a long time after obtaining the water production signal by judging whether the interval duration is greater than or equal to the preset duration. If so, the first flushing signal is generated to flush the filter element of the filtration system. Then, the flushed filter element is used to prepare pure water, further improving the purity of the pure water.

[0069] In one embodiment, after the step of controlling the flushing solenoid valve to close if the flushing duration exceeds a preset flushing time, the method further includes:

[0070] S501: Control the opening of the water inlet solenoid valve and the start of the filtration system, wherein the filtration system prepares purified water from the tap water pressurized by the booster pump, and the purified water discharged from the purified water outlet is stored in the purified water storage container through the first one-way valve;

[0071] S502: When the water pressure in the pure water discharge pipe is equal to the preset water pressure, close the inlet solenoid valve, the booster pump, and the filtration system.

[0072] In this embodiment, firstly, the inlet solenoid valve is opened to allow tap water to flow in, and simultaneously the filtration system is activated, putting it into a state of producing purified water. The activated filtration system uses the tap water pressurized by the booster pump to produce purified water. The purified water discharged from the outlet is stored in a purified water storage container via a first one-way valve. When the water pressure in the purified water outlet pipe equals the preset water pressure, it means that the purified water in the storage container meets the demand, thus closing the inlet solenoid valve, the booster pump, and the filtration system to stop water production.

[0073] The water purifier flushing method proposed in this embodiment controls the opening of the inlet solenoid valve and the start of the filtration system. The filtration system prepares purified water from the tap water pressurized by the booster pump. The purified water discharged from the purified water outlet is stored in the purified water storage container through the first one-way valve. Then, when the water pressure in the purified water outlet pipe equals the preset water pressure, the inlet solenoid valve, the booster pump, and the filtration system are closed. The filtration system can use the flushed filter cartridge to prepare purified water, thereby further improving the purity of the purified water.

[0074] In one embodiment, such as Figure 3 As shown, the water purifier also includes a concentrated water solenoid valve 13 and a second pressure sensor 14; the other end of the concentrated water drain pipe 12 is connected to the concentrated water solenoid valve 13, and the concentrated water drain pipe 12 is provided with the second pressure sensor 14, which is used to detect the water pressure of the concentrated water drain pipe 12.

[0075] The method further includes:

[0076] S601: Obtain concentrated water discharge signal;

[0077] S602: In response to the concentrated water discharge signal, determine whether the water pressure of the concentrated water drain pipe is greater than or equal to the preset discharge water pressure;

[0078] S603: If the water pressure in the concentrated water drain pipe is greater than or equal to the preset discharge water pressure, the concentrated water solenoid valve is opened so that the concentrated water in the concentrated water storage container is discharged from the concentrated water drain outlet of the water purifier through the concentrated water drain pipe and the concentrated water solenoid valve in sequence.

[0079] The concentrated water discharge signal can be a signal generated by the user triggering the concentrated water discharge button, the preset discharge water pressure can be a water pressure set by the user in advance, or the water pressure when the concentrated water storage container is full of concentrated water.

[0080] In this embodiment, a concentrated water discharge signal is acquired. Then, in response to the concentrated water discharge signal, it is determined whether the water pressure in the concentrated water drain pipe is greater than or equal to the preset discharge pressure. When the water pressure in the concentrated water drain pipe is greater than or equal to the preset discharge pressure, it means that the concentrated water in the concentrated water storage container has met the discharge requirements. Therefore, the concentrated water solenoid valve is opened, allowing the concentrated water in the concentrated water storage container to be discharged from the water purifier sequentially through the concentrated water drain pipe, the concentrated water solenoid valve, and the concentrated water drain outlet.

[0081] The water purifier flushing method proposed in this embodiment obtains a concentrated water discharge signal, then responds to the concentrated water discharge signal to determine whether the water pressure of the concentrated water drain pipe is greater than or equal to a preset discharge water pressure. If the water pressure of the concentrated water drain pipe is greater than or equal to the preset discharge water pressure, the concentrated water solenoid valve is controlled to open, so that the concentrated water in the concentrated water storage container is discharged from the water purifier through the concentrated water drain pipe and the concentrated water solenoid valve in sequence. This method can discharge the concentrated water in the concentrated water storage container when the water pressure in the concentrated water drain pipe is greater than or equal to the preset discharge water pressure, thus ensuring that the concentrated water in the concentrated water storage container is discharged in a reasonable manner.

[0082] In one embodiment, such as Figure 4 As shown, the water purifier also includes: a water flow sensor 15, a tap water pipe 16, and a tap water faucet 17. One end of the water inlet solenoid valve 01 is connected to one end of the tap water pipe 16, the other end of the tap water pipe 16 is connected to the tap water faucet 17, and the other end of the concentrated water drain pipe 12 is connected to the tap water faucet 17. The tap water pipe 16 is equipped with the water flow sensor 15.

[0083] The method further includes:

[0084] S701: If the water flow sensor detects a water flow signal and the water pressure in the purified water discharge pipe is less than the preset water pressure, then the inlet solenoid valve is opened, the booster pump is started, and the filtration system is started to control the filtration system to prepare purified water. The concentrated water discharged from the concentrated water discharge end and the tap water in the tap water pipe are discharged from the tap water faucet.

[0085] In this embodiment, if the water flow sensor detects a water flow signal, it means that the tap water faucet 17 is turned on. If the water pressure in the purified water discharge pipe is less than the preset water pressure, it means that there is less purified water in the purified water storage container. This controls the inlet solenoid valve to open, the booster pump to start, and the filtration system to start, so as to control the filtration system to prepare purified water. The concentrated water discharged from the concentrated water discharge end and the tap water in the tap water pipe are discharged from the tap water faucet. The concentrated water discharged from the concentrated water discharge end of the tap water faucet and the tap water in the tap water pipe can be used in scenarios with low water quality requirements, such as cleaning toilets.

One end of the flushing solenoid valve is connected to the second end of the first check valve, and the other end is connected to the first end of the second check valve. The second end of the second check valve is connected to one end of the booster pump. The purified water discharge pipe is connected to the second end of the first check valve and is equipped with the first pressure sensor and the purified water storage container. The first pressure sensor is used to detect the water pressure in the purified water discharge pipe.

[0088] The water purifier flushing device includes:

[0089] Acquisition module 20 is used to acquire the first flushing signal;

[0090] The first response module 30 is used to respond to the first flushing signal and determine whether the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure.

[0091] The control module 40 is used to control the water inlet solenoid valve to close, the booster pump to open, and the filtration system to open if the water pressure in the pure water discharge pipe is greater than or equal to the preset water pressure. The control module 40 controls the filtration system to process the tap water remaining in the booster pump and the filtration system into pure water and obtains a ready signal.

[0092] The second response module 50 is used to respond to the ready signal, control the flushing solenoid valve to open, the booster pump to pressurize, and the filtration system to flush the filter element.

Finally, in response to the ready signal, the flushing solenoid valve is opened, the booster pump pressurizes the water, and the filtration system flushes the filter element. In this system, the purified water in the purified water discharge pipe and the purified water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve to flush the filter element of the filtration system. When the water pressure in the purified water discharge pipe is greater than or equal to the preset water pressure, the filter element can be flushed with purified water. The purified water meets the water output requirements of the water purifier. Using purified water to flush the filter element can improve the flushing effect and greatly extend the service life of the filter element. In addition, compared with flushing the filter element with tap water, using purified water to flush the filter element can achieve a better flushing effect with less purified water, thereby saving water resources.

[0097] Based on the generation time of the water production signal and the generation time of the target flushing signal, calculate the interval duration and determine whether the interval duration is greater than or equal to the preset duration.

[0098] If the interval duration is greater than or equal to the preset duration, then the first flushing signal is generated.

[0099] In one embodiment, the water purifier flushing device is further used to control the opening of the inlet solenoid valve and the start of the filtration system, wherein the filtration system prepares purified water from the tap water pressurized by the booster pump, and the purified water discharged from the purified water outlet is stored in the purified water storage container through the first one-way valve; when the water pressure in the purified water outlet pipe is equal to the preset water pressure, the inlet solenoid valve, the booster pump, and the filtration system are closed.
