[0031] Among them, the water inlet solenoid valve 01 is a solenoid valve used to control the flow of tap water flowing out of 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 pure water passing through the booster pump 02.

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

[0033] See also Figure 2 As shown, Figure 2A schematic flow chart of a method for flushing a water purifier provided in one embodiment of the present invention is provided. The method is applied to a water purifier and comprises the following steps:

[0034] S101: Acquire a first flushing signal;

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

[0036] Optionally, the first flushing signal is actively triggered by the program file implementing the present application according to a preset condition. For example, the preset condition is that a flushing signal is actively triggered when the filtering time exceeds 10 hours, and the flushing signal is used as the first flushing signal.

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

[0038] In this embodiment, after obtaining the first flushing signal, the first signal is responded to so as to judge 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 pure water storage container is filled with water, the water pressure of the pure water discharge pipe is detected to obtain the maximum water pressure, and the maximum water pressure is used as the preset water pressure.

[0040] S103: If the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure, the water inlet solenoid valve is controlled to be closed, the booster pump is turned on, and the filter system is turned on, and the filter system is controlled to prepare the remaining tap water in the booster pump and the filter system into pure water, and a ready signal is obtained;

[0041] In one implementation, when the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure, it is determined whether the water inlet solenoid valve is closed. If not, the water inlet solenoid valve is controlled to be closed; it is determined whether the boosting pump is turned on. If not, the boosting pump is controlled to be turned on; it is determined whether the filtration system is turned on. If not, the filtration system is controlled to be turned on.

[0042] After determining that the filter system is turned on, the filter system is controlled to prepare the booster pump and the remaining tap water in the filter system into pure water, thereby obtaining a ready signal.

[0043] S104: In response to the ready signal, the flushing solenoid valve is controlled to open, the boosting pump is controlled to perform pressurization, and the filter system is controlled to perform filter element flushing, wherein the pure water in the pure water discharge pipe and the pure water storage container enters one end of the boosting pump through the flushing solenoid valve and the second one-way valve to be used for flushing the filter element of the filter system.

[0044] In one implementation, when a ready signal is detected, the flushing solenoid valve is controlled to open in response to the ready signal, so that the pure water in the pure water discharge pipe and the pure water in the pure water storage container enter one end of the boosting pump through the flushing solenoid valve and the second one-way valve, and the boosting pump collects the pressurized pure water from the other end of the boosting pump into the filtration system, and the filtration system uses the pure water in the pure water discharge pipe and the pure water in 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, determines whether the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure, and then if the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure, controls the water inlet solenoid valve to be closed, the booster pump to be opened, and the filter system to be opened, controls the filter system to prepare the remaining tap water in the booster pump and the filter system into pure water, obtains a ready signal, and finally responds to the ready signal to control the flushing solenoid valve to be opened, the booster pump to be pressurized, and the filter system to flush the filter element. In the method, the pure water in the pure water discharge pipe and the pure water storage container enters one end of the boost 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 pure water discharge pipe is greater than or equal to the preset water pressure, the filter element can be flushed with pure water. Pure water is water that meets the water outlet requirements of the water purifier. Flushing the filter element with pure water 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, flushing the filter element with pure water can achieve better flushing effect with less pure water, thereby saving water.

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

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

[0048] S202: When the water pressure of the pure water discharge pipe is less than the preset water pressure, the water inlet solenoid valve is controlled to open, the booster pump is started, and the filtration system is started, wherein the filtration system prepares pure water from the tap water pressurized by the booster pump, and 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 to execute until the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure.

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

[0051] Then jump 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 continue to execute, thereby continuously preparing 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 demand.

[0052] The water purifier flushing method proposed in this embodiment determines whether the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure, and then when the water pressure of the pure water discharge pipe is less than the preset water pressure, controls the water inlet solenoid valve to open, the booster pump to start and the filter system to start, wherein the filter system prepares pure water for the tap water pressurized by the booster pump, and the pure water discharged from the pure water discharge end is stored in the pure water storage container through the first one-way valve, and then jumps 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 continues to execute until the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure, and can continuously prepare pure water when the water pressure of the pure water discharge pipe is less than the preset water pressure, and then use pure water to flush the filter element when the water pressure of the pure water discharge pipe is greater than or equal to the preset water pressure, thereby improving the flushing effect and greatly extending the service life of the filter element. In addition, compared with flushing the filter element with tap water, flushing the filter element with pure water can achieve a better flushing effect with less pure water, thereby saving water.

[0053] In one embodiment, if Figure 3As shown, the water purifier further includes a concentrated water storage container 11 and a concentrated water drainage pipe 12, the concentrated water discharge end of the filtration system is connected to one end of the concentrated water drainage pipe 12, and the concentrated water storage container 11 is provided on the concentrated water drainage pipe 12;

[0054] In response to the ready signal, controlling the flushing solenoid valve to open, the booster pump to perform pressurization, and the filter system to perform filter element flushing includes:

[0055] S301: In response to the ready signal, control the flushing solenoid valve to open, the booster pump to perform pressurization, and the filter system to perform filter element flushing, so that the concentrated water generated by the filter system and 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 flushing time of the filtration system, and determine whether the flushing time is greater than a preset flushing time;

[0057] S303: If the flushing time is longer than the preset flushing time, the flushing solenoid valve is controlled to close.

[0058] In this embodiment, in response to the ready signal, the flushing solenoid valve is controlled to open, the booster pump is pressurized, and the filter system is flushed, so that the concentrated water generated by the filter system corresponding to the ready signal is discharged into the concentrated water storage container through the concentrated water discharge end and the concentrated water drainage pipe, thereby realizing the collection of concentrated water. If the concentrated water in 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 drainage pipe.

[0059] Next, the flushing time of the filtration system is obtained to determine whether the flushing time is greater than the preset flushing time, wherein the preset flushing time may be a factory setting set by human experience or may be set by the user. When the flushing time is greater than the preset flushing time, it means that the time for flushing the filter element of the water purifier has met the preset flushing time, and the flushing solenoid valve is controlled to close to stop flushing the filter element.

[0060] The water purifier flushing method proposed in the present embodiment responds to the ready signal to control the flushing solenoid valve to open, the boosting pump to perform boosting, and the filter system to perform filter element flushing, so that the concentrated water generated by the filter system and 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, and then the flushing time of the filter system is obtained to determine whether the flushing time is greater than the preset flushing time. If the flushing time is greater than the preset flushing time, the flushing solenoid valve is controlled to close, and the concentrated water generated by the filter element flushing can be collected through the concentrated water storage container, which is conducive to subsequent unified discharge, and when the flushing time reaches the preset flushing time, the flushing is stopped, thereby improving the automation level of the flushing water purifier and improving the user experience.

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

[0062] S401: Acquire a water production signal, and in response to the water production signal, acquire a generation time of a target flushing signal, wherein the target flushing signal is a second flushing signal with the latest generation time among 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: Calculating the interval duration according to the generation time of the water production signal and the generation time of the target flushing signal, and determining whether the interval duration is greater than or equal to a preset duration;

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

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

[0066] Next, the interval duration is calculated according to 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 target flushing signal is subtracted from the generation time of the water production signal to obtain the interval duration. Then, it is determined whether the interval duration is greater than or equal to a preset duration, wherein the preset duration may be preset by the user or set by the factory.

[0067] When the interval time is greater than or equal to the preset time, it means that the filter element of the water purifier has not been cleaned for a long time and the filter element may have stains. Therefore, a first flushing signal is generated to allow the filtration system to flush the filter element, thereby improving the purity of the prepared pure water.

[0068] The water purifier flushing method proposed in this embodiment obtains a water production signal and responds to the water production signal to obtain the generation time of a target flushing signal, wherein the target flushing signal is the second flushing signal with the latest generation time among the second flushing signals, and the generation time of the second flushing signal is earlier than the generation time of the first flushing signal. Then, according to the generation time of the water production signal and the generation time of the target flushing signal, the interval duration is calculated, and it is judged whether the interval duration is greater than or equal to the preset duration. If the interval duration is greater than or equal to the preset duration, the first flushing signal is generated. After obtaining the water production signal, it can be determined whether the water purifier has not been flushed for a long time by judging whether the interval duration is greater than or equal to the preset duration. If so, the first flushing signal is generated to enable the filtration system to flush the filter element, and then the flushed filter element is used to prepare pure water, so that the purity of the pure water is further improved.

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

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

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

[0072] In this embodiment, first, the water inlet solenoid valve is controlled to open to allow tap water to flow in, and the filter system is started at the same time, so that the filter system is in a state of preparing pure water, wherein the activated filter system prepares pure water from the tap water pressurized by the booster pump, and the pure water discharged from the pure water discharge end is stored in the pure water storage container through the first one-way valve, and the prepared pure water is stored in the pure water storage container. When the water pressure of the pure water discharge pipe is equal to the preset water pressure, it means that the pure water in the pure water storage container has met the demand, so the water inlet solenoid valve, the booster pump and the filter system are closed to stop water production.

[0073] The water purifier flushing method proposed in this embodiment controls the water inlet solenoid valve to open and the filter system to start, wherein the filter system prepares pure water from the tap water pressurized by the booster pump, and the pure water discharged from the pure water discharge end is stored in the pure water storage container through the first one-way valve. Then, when the water pressure in the pure water discharge pipe is equal to the preset water pressure, the water inlet solenoid valve, the booster pump and the filter system are closed, and the filter system of the flushed filter element can be used to prepare pure water, so that the purity of the pure water is further improved.

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

[0075] The method further comprises:

[0076] S601: Acquire a concentrated water discharge signal;

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

[0078] S603: If the water pressure of the concentrated water drainage 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 from the concentrated water drainage port through the concentrated water drainage pipe and the concentrated water solenoid valve in turn.

[0079] Among them, 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 the water pressure preset by the user, and the preset discharge water pressure can also be the water pressure when the concentrated water storage container is full of concentrated water.

[0080] In this embodiment, a concentrated water discharge signal is obtained, and then, after obtaining the concentrated water discharge signal, it is determined in response to the concentrated water discharge signal whether the water pressure of the concentrated water drainage pipe is greater than or equal to the preset discharge water pressure. When the water pressure of the concentrated water drainage pipe is greater than or equal to the preset discharge water pressure, it means that the concentrated water in the concentrated water storage container has met the discharge requirements, and 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 drainage pipe, the concentrated water solenoid valve and the concentrated water drainage port in sequence.

[0081] The water purifier flushing method proposed in the present embodiment obtains a concentrated water discharge signal, then responds to the concentrated water discharge signal, determines whether the water pressure in the concentrated water drainage pipe is greater than or equal to a preset discharge water pressure, and then if the water pressure in the concentrated water drainage pipe is greater than or equal to the preset discharge water pressure, controls the concentrated water solenoid valve to open, so that the concentrated water in the concentrated water storage container is discharged from the concentrated water drainage port through the concentrated water drainage pipe and the concentrated water solenoid valve in turn. The concentrated water in the concentrated water storage container can be discharged when the water pressure in the concentrated water drainage pipe is greater than or equal to the preset discharge water pressure, so that the concentrated water in the concentrated water storage container is discharged reasonably.

[0082] In one embodiment, if Figure 4 As shown, the water purifier further 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, the other end of the concentrated water drainage pipe 12 is connected to the tap water faucet 17, and the tap water pipe 16 is provided with the water flow sensor 15;

[0083] The method further comprises:
