[0028] Among them, the water inlet solenoid valve 01 is a solenoid valve used to control the tap water flowing into the tap water inlet 00 to flow to the booster pump 02.

[0030] See also Figure 2 As shown, Figure 2 A 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:

[0031] S101: Acquire a first container cleaning signal;

[0032] Optionally, the user may obtain a first container cleaning signal by triggering a cleaning function button of the water purifier.

[0033] Optionally, the first container cleaning signal is actively triggered by the program file implementing the present application according to a preset condition. For example, the preset condition is that if the filtering time exceeds 10 hours, a container cleaning signal is actively triggered, and the container cleaning signal is used as the first container cleaning signal.

[0034] As another example, the water purifier further includes a water quality probe, and the purified water storage container is provided with the water quality probe, and the water quality probe is used to detect the water quality of purified water in the purified water storage container, wherein the water quality probe can be provided at the bottom of the purified water storage container. The water quality probe can be used to detect the purity of purified water in the purified water storage container, and if the purity of purified water in the purified water storage container does not meet the preset standard, it means that the inside of the purified water storage container needs to be cleaned, and a first container cleaning signal is generated.

[0035] S102: In response to the first container cleaning signal, the flushing solenoid valve is controlled to open, so that the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve, and flows out from the concentrated water discharge end of the filtration system to the concentrated water drainage pipeline, and a first emptying signal is generated when the pure water in the pure water storage container is emptied;

[0036] In this embodiment, after obtaining the first container cleaning signal, the first container cleaning signal is responded to, thereby controlling the flushing solenoid valve to open. After the flushing solenoid valve is opened, the pure water in the pure water storage container sequentially passes through the flushing solenoid valve and the second one-way valve into one end of the booster pump, and finally flows out from the concentrated water discharge end of the filtration system to the concentrated water drainage pipeline, and finally the pure water in the pure water storage container is emptied. As an example, the pure water in the pure water storage container is discharged through the concentrated water drainage pipeline.

[0037] Next, determine whether the pure water in the pure water storage container is emptied. When the pure water in the pure water storage container is emptied, generate a first emptying signal. As an example, detect the water pressure of the pure water discharge pipe through a first pressure sensor to determine whether the pure water storage container has been emptied.

[0038] S103: In response to the first emptying signal, control the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start, so that the pure water prepared by the filtration system is stored in the pure water storage container through the pure water discharge end and the first one-way valve.

[0039] Among them, the filtration system startup refers to starting the pure water preparation function of the filtration system.

[0040] In this embodiment, first, in response to the first emptying signal, the water inlet solenoid valve is controlled to open, the booster pump is started, and the filtration system is started, so that the tap water passing through the water inlet solenoid valve is pressurized by the booster pump and flows into the filtration system for pure water preparation. The pure water prepared by the filtration system is sequentially stored in the pure water storage container through the pure water discharge end and the first one-way valve to obtain the latest prepared pure water, which means that the pure water with a long time and low purity in the pure water storage container has been emptied, and pure water with a higher purity is newly prepared and stored in the pure water storage container.

[0041] The water purifier cleaning method proposed in this embodiment obtains a first container cleaning signal, and then responds to the first container cleaning signal to control the flushing solenoid valve to open, so that the pure water in the pure water storage container enters one end of the boosting pump through the flushing solenoid valve and the second one-way valve, and flows out from the concentrated water discharge end of the filtration system to the concentrated water drainage pipe. When the pure water in the pure water storage container is emptied, a first emptying signal is generated, and then in response to the first emptying signal, the water inlet solenoid valve is controlled to open, the boosting pump is started, and the filtration system is started, so that the pure water prepared by the filtration system is stored in the pure water storage container through the pure water discharge end and the first one-way valve. By responding to the first container cleaning signal, the pure water with low purity that has been stored for a long time in the pure water storage container can be emptied, so that the pure water that may be deteriorated can be discharged from the pure water storage container, and then the pure water with high purity can be prepared and stored in the pure water storage container, so as to avoid the pure water storage container from discharging deteriorated pure water for users to use, so that users always obtain non-deteriorated pure water, thereby improving user experience.

[0042] In one embodiment, in response to the first emptying signal, controlling the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start, so that the pure water prepared by the filtration system passes through the pure water discharge end and the first one-way valve and is stored in the pure water storage container, includes:

[0043] S201: In response to the first emptying signal, control the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start, so that the pure water prepared by the filtration system passes through the pure water discharge end and the first one-way valve and is stored in the pure water storage container;

[0044] In this embodiment, first, in response to the first emptying signal, the water inlet solenoid valve is controlled to open, the booster pump is started, and the filtration system is started, so that the tap water passing through the water inlet solenoid valve is pressurized by the booster pump and flows into the filtration system for pure water preparation. The pure water prepared by the filtration system is sequentially stored in the pure water storage container through the pure water discharge end and the first one-way valve to obtain the latest prepared pure water, which means that the pure water with a long time and low purity in the pure water storage container has been emptied, and pure water with a higher purity is newly prepared and stored in the pure water storage container.

[0045] S202: If the water pressure of the pure water discharge pipe is greater than the preset discharge water pressure, the water inlet solenoid valve is controlled to be closed, the filter system is closed, and the flushing solenoid valve is controlled to be opened, so that the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve, and flows out from the concentrated water discharge end of the filter system to the concentrated water drainage pipe, and a second emptying signal is generated when the pure water in the pure water storage container is emptied;

[0046] The preset discharge water pressure may be a water pressure set at the factory, and of course, the preset discharge water pressure may also be a user-defined water pressure. As an example, when the purified water storage container is full of water, the water pressure of the purified water discharge pipe is detected to obtain the maximum water pressure, and the preset discharge water pressure is less than or equal to the maximum water pressure. As another example, when the purified water in the purified water storage container is half the capacity of the purified water storage container, the water pressure of the purified water discharge pipe is detected at this time to obtain the target water pressure, and the preset discharge water pressure is less than or equal to the target water pressure.

[0047] In this embodiment, when the water pressure of the pure water discharge pipe is greater than the preset discharge water pressure, it means that a certain amount of pure water corresponding to the discharge water pressure has been stored in the pure water storage container. As an example, the pure water storage container can be cleaned using a certain amount of pure water stored in the pure water storage container. As another example, the pure water storage container is equipped with an electric brush, and the cleaning brush head of the electric brush fits the inner wall of the pure water storage container. When the water pressure of the pure water discharge pipe is greater than the preset discharge water pressure, the electric brush is started, and the electric brush uses a certain amount of pure water stored in the pure water storage container to clean the inner wall of the pure water storage container.

[0048] When it is detected that the water pressure of the pure water discharge pipe is greater than the preset discharge water pressure, the water inlet solenoid valve is controlled to be closed, the filter system is closed, and the flushing solenoid valve is opened, so that the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve, and flows out from the concentrated water discharge end of the filter system to the concentrated water drainage pipe, and generates a second emptying signal when the pure water in the pure water storage container is emptied. The pure water in the pure water storage container is emptied for the second time, and the water that may remain in the pure water storage container after the first emptying is cleaned, making the pure water storage container cleaner, wherein the filtration system is closed refers to the function of closing the pure water preparation of the filtration system.

[0049] S203: In response to the second emptying signal, control the water inlet solenoid valve to open, the flushing solenoid valve to close, and the filtration system to start, so that the pure water prepared by the filtration system is stored in the pure water storage container through the pure water discharge end and the first one-way valve.

[0050] In this embodiment, in response to the second emptying signal, the water inlet solenoid valve is opened, the flushing solenoid valve is closed and the filtration system is started, so that the tap water passing through the water inlet solenoid valve is pressurized by the booster pump and flows into the filtration system for pure water preparation.

[0051] Next, the pure water prepared by the filtration system is stored in a cleaner pure water storage container through the pure water discharge end and the first one-way valve, thereby further improving the purity of the pure water and avoiding the purity of the pure water being affected by the fact that the pure water storage container is not clean enough.

[0052] The water purifier cleaning method proposed in this embodiment controls the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start in response to the first emptying signal, so that the pure water prepared by the filtration system is stored in the pure water storage container through the pure water discharge end and the first one-way valve. Then, if the water pressure in the pure water discharge pipe is greater than the preset discharge water pressure, the water inlet solenoid valve is closed, the filtration system is closed, and the flushing solenoid valve is opened, so that the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve, and flows out from the concentrated water discharge end of the filtration system to the concentrated water drainage pipe. When the pure water in the pure water storage container is emptied, A second emptying signal is generated, and then in response to the second emptying signal, the water inlet solenoid valve is controlled to be opened, the flushing solenoid valve is closed and the filtration system is started, so that the pure water prepared by the filtration system is stored in the pure water storage container through the pure water discharge end and the first one-way valve, and when the water pressure in the pure water discharge pipe is greater than the preset discharge water pressure, the pure water in the pure water storage container can be emptied for the second time, the pure water storage container is cleaned, and the pure water storage container is made cleaner, and the pure water prepared by the filtration system is again stored in a cleaner pure water storage container through the pure water discharge end and the first one-way valve, thereby further improving the purity of the pure water and avoiding the purity of the pure water being affected by the fact that the pure water storage container is not clean enough.

[0053] In one embodiment, in response to the second drain signal, controlling the water inlet solenoid valve to open, the booster pump to start, the sewage discharge solenoid valve to close, and the filtration system to start, comprises:

[0054] S301: adding the second drain signal to a preset drain signal set;

[0055] In this embodiment, the second emptying signal is added to a preset emptying signal set, and the second emptying signal is collected through the emptying signal set.

[0056] S302: if the number of the second emptying signals in the emptying signal set is less than a preset number, returning the response to the first emptying signal, controlling the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start, so that the steps of allowing the purified water prepared by the filtration system to pass through the purified water discharge end and the first one-way valve and be stored in the purified water storage container are repeated;

[0057] In this embodiment, it is determined whether the number of the second emptying signals in the emptying signal set is less than a preset number, wherein the preset number may be manually preset or factory set. If the number of the second emptying signals in the emptying signal set is less than the preset number, this means that the number of times the purified water in the purified water storage container is emptied does not meet the requirement. Then the step of S201 is returned to be repeated until the number of the second emptying signals in the emptying signal set is greater than or equal to the preset number.

[0058] S303: If the number of the second emptying signals in the emptying signal set is greater than or equal to a preset number, the water inlet solenoid valve is controlled to open, the flushing solenoid valve is controlled to close, and the filtration system is started, so that the pure water prepared by the filtration system passes through the pure water discharge end and the first one-way valve and is stored in the pure water storage container.

[0059] In this embodiment, when the number of the second emptying signals in the emptying signal set is greater than or equal to the preset number, it means that the number of times the pure water in the pure water storage container has been emptied has met the demand, and the water inlet solenoid valve is controlled to open, the flushing solenoid valve is closed and the filtration system is started, so that the pure water prepared by the filtration system is stored in the pure water storage container through the pure water discharge end and the first one-way valve, thereby realizing multiple emptying of the pure water in the pure water storage container, making the pure water storage container cleaner, and then the pure water prepared by the filtration system is stored in a cleaner pure water storage container through the pure water discharge end and the first one-way valve, thereby further improving the purity of the pure water and avoiding the purity of the pure water being affected by the pure water storage container being not clean enough.

[0060] The water purifier cleaning method proposed in this embodiment adds the second drain signal to the preset drain signal set, and then if the number of the second drain signals in the drain signal set is less than the preset number, returns the response to the first drain signal, controls the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start, so that the steps of allowing the purified water prepared by the filtration system to pass through the purified water discharge end and the first one-way valve to be stored in the purified water storage container are repeated, and finally if the number of the second drain signals in the drain signal set is greater than or equal to the preset number, controls the The water inlet solenoid valve is opened, the flushing solenoid valve is closed and the filtration system is started, so that the pure water prepared by the filtration system is stored in the pure water storage container through the pure water discharge end and the first one-way valve. The pure water in the pure water storage container can be stored and drained multiple times to clean the pure water storage container. Then, the pure water prepared by the filtration system is stored in a cleaner pure water storage container through the pure water discharge end and the first one-way valve, thereby further improving the purity of the pure water and avoiding the purity of the pure water being affected by the pure water storage container being not clean enough.

[0061] In one embodiment, if the water pressure of the pure water discharge pipe is greater than the preset discharge water pressure, the water inlet solenoid valve is controlled to be closed, the filter system is closed, and the flushing solenoid valve is controlled to be opened, so that the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve, and flows out from the concentrated water discharge end of the filter system to the concentrated water drainage pipe, and a second emptying signal is generated when the pure water in the pure water storage container is emptied, including:

[0062] S401: If the water pressure of the pure water discharge pipe is greater than the discharge water pressure, a filter element flushing signal is generated;

[0063] In this embodiment, first, it is determined whether the water pressure of the pure water discharge pipe is greater than the discharge water pressure. When the water pressure of the pure water discharge pipe is greater than the discharge water pressure, a filter element flushing signal is generated.

[0064] S402: In response to the filter element flushing signal, the water inlet solenoid valve is controlled to be closed, the filter system is closed, the flushing solenoid valve is controlled to be opened, and the filter system performs filter element flushing, wherein the pure water in 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, and the flushing water discharged from the concentrated water discharge end of the filter system flows into the concentrated water drainage pipe;

[0065] In this embodiment, in response to the filter element flushing signal, the water inlet solenoid valve is controlled to be closed, the filter system is closed, the flushing solenoid valve is opened, and the filter system performs filter element flushing, so that the filter system can use pure water to flush the filter element, improve the flushing effect, and extend the life of the filter element. The pure water flushing filter element uses less pure water to achieve a better flushing effect, thereby saving water. Among them, closing the filter system means closing the pure water preparation function of the filter system, and the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve to be used for flushing the filter element of the filter system. The flushing water generated by the filter system flushing the filter element is discharged through the concentrated water discharge end and flows into the concentrated water drainage pipeline.

[0066] S403: When the purified water in the purified water storage container is emptied, the filtration system is controlled to stop flushing the filter element and generate a second emptying signal.

[0067] In this embodiment, it is determined whether the purified water in the purified water storage container is emptied. When the purified water in the purified water storage container is emptied, it means that the filter system has completed the filter element flushing and all the flushing water generated by flushing the filter element is discharged through the concentrated water discharge end. After the filter element flushing is completed, the filter system is controlled to stop the filter element flushing.

[0068] The water purifier cleaning method proposed in this embodiment generates a filter element flushing signal if the water pressure of the pure water discharge pipe is greater than the discharge water pressure, and then controls the water inlet solenoid valve to close, the filter system to close, the flushing solenoid valve to open, and the filter system to flush the filter element in response to the filter element flushing signal, wherein the pure water in 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, and the flushing water discharged from the concentrated water discharge end of the filter system flows into the concentrated water drainage pipe, and then when the pure water in the pure water storage container is emptied, the filter system is controlled to stop flushing the filter element and generate a second emptying signal, and when the water pressure of the pure water discharge pipe is greater than the discharge water pressure, a filter element flushing signal is generated to flush the filter element of the filter system, and when the filter element flushing is completed, the pure water in the pure water storage container is emptied, and then the pure water prepared by the filter system after the filter element is flushed can be stored in the pure water storage container, thereby further improving the purity of the pure water.

[0069] In one embodiment, obtaining the first container cleaning signal includes:

[0070] S501: obtaining a water production signal, and in response to the water production signal, obtaining a target cleaning time, wherein the target cleaning time is the latest time among the generation times corresponding to the second container cleaning signals, and the generation time of the second container cleaning signal is earlier than the generation time of the first container cleaning signal;

[0071] In this embodiment, a water production signal is first obtained, wherein the water production signal can be obtained by a user by triggering a water production button. In response to the water production signal, a target cleaning time is obtained, and the target cleaning time is the latest time among the generation times corresponding to the second container cleaning signals. The generation time of the second container cleaning signal is earlier than the generation time of the first container cleaning signal, and the second container cleaning signal is a container cleaning signal generated in the past.

[0072] S502: Calculating a first interval duration according to the generation time of the water production signal and the target cleaning time;

[0073] In this embodiment, the interval duration is calculated according to the generation time of the water production signal and the target cleaning time. As an example, the generation time of the water production signal is subtracted from the target cleaning time 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.

[0074] S503: If the interval duration is greater than or equal to a preset first duration, the first container cleaning signal is generated.

[0075] In this embodiment, it is determined whether the interval duration is greater than or equal to a preset first duration. When the interval duration is greater than or equal to the preset duration, this means that the pure water storage container of the water purifier has not been cleaned for a long time, and the pure water storage container may have stains. Therefore, a first container cleaning signal is generated to rinse the pure water storage container, thereby improving the purity of the pure water preparation.

[0076] The water purifier cleaning method proposed in this embodiment obtains a water production signal and responds to the water production signal to obtain a target cleaning time, wherein the target cleaning time is the latest time among the generation times corresponding to the second container cleaning signals, and the generation time of the second container cleaning signal is earlier than the generation time of the first container cleaning signal. Then, according to the generation time of the water production signal and the target cleaning time, a first interval duration is calculated, and then if the interval duration is greater than or equal to a preset first duration, the first container cleaning signal is generated. After obtaining the water production signal, it can be determined whether the pure water storage container has not been cleaned for a long time by judging whether the interval duration is greater than or equal to the preset duration. If so, a first container cleaning signal is generated to clean the pure water storage container, and then the cleaned pure water storage container is used to store pure water, so that the purity of the pure water is further improved.

[0077] In one embodiment, if Figure 3As shown, the water purifier includes a concentrated water storage container 12 and a concentrated water solenoid valve 13. The concentrated water storage container 12 is arranged on the concentrated water drainage pipe 11, and the other end of the concentrated water drainage pipe 11 is connected to the concentrated water solenoid valve 13;

[0078] The method of responding to the first container cleaning signal and controlling the flushing solenoid valve to open so that the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve, and flows out from the concentrated water discharge end of the filtration system to the concentrated water drainage pipeline includes:

[0079] S601: In response to the first container cleaning signal, the flushing solenoid valve is controlled to open, so that the pure water in the pure water storage container enters one end of the boosting pump through the flushing solenoid valve and the second one-way valve, and flows from the concentrated water discharge end of the filtration system into the concentrated water storage container on the concentrated water drainage pipe.

[0080] In this embodiment, in response to the first container cleaning signal, the flushing solenoid valve is controlled to open, so that the pure water in the pure water storage container enters one end of the booster pump through the flushing solenoid valve and the second one-way valve, and flows from the concentrated water discharge end of the filtration system into the concentrated water storage container on the concentrated water drainage pipe. As an example, a concentrated water emptying signal is obtained, and in response to the concentrated water emptying signal, the concentrated water solenoid valve is controlled to open so that the water in the concentrated water storage container is discharged through the concentrated water drainage pipe, and the discharged water can be used in places with lower water quality requirements, such as flushing toilets.

[0081] The water purifier cleaning method proposed in this embodiment responds to the first container cleaning signal to control the flushing solenoid valve to open, so that the pure water in the pure water storage container enters one end of the boosting pump through the flushing solenoid valve and the second one-way valve, and flows from the concentrated water discharge end of the filtration system into the concentrated water storage container on the concentrated water drainage pipe, so that the pure water in the pure water storage container can be discharged into the concentrated water storage container for storage, which is conducive to the subsequent discharge of water in the concentrated water storage container.

[0082] In one embodiment, the pure water storage container includes a water storage electric control switch, and the step of responding to the first emptying signal to control the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start, so that the pure water prepared by the filtration system passes through the pure water discharge end and the first one-way valve and is stored in the pure water storage container includes:

[0083] Wherein, the water storage electric control switch is an electric control switch

[0084] S701: In response to the first emptying signal, control the water inlet solenoid valve to open, the booster pump to start, and the filtration system to start, and start a preset timer;

[0085] S702: Acquire the second duration recorded by the timer in real time;

[0086] S703: when the second time period is less than the preset third time period, turning off the water storage electric control switch so that the pure water prepared by the filtration system is discharged through the pure water discharge end;

[0087] S704: When the second time period is greater than the third time period, the water storage electric control switch is turned on to allow the pure water prepared by the filtration system to be stored in the pure water storage container through the pure water discharge end and the first one-way valve.

[0088] In this embodiment, in response to the first emptying signal, the water inlet solenoid valve is controlled to open, the booster pump is started, and the filtration system is started, and a preset timer is started. The timer can be used for timing. As an example, the starting timing time of the timer is 0 minutes and 0 seconds. The second duration recorded by the timer is obtained in real time, and the second duration refers to the duration recorded by the timer.

[0089] Next, it is determined whether the second time duration is less than the preset third time duration. When the second time duration is less than the preset third time duration, it means that the time for the filtration system to prepare pure water is not long enough, and there may be residual water stains or impurities such as dust in the pipe of the water purifier. As an example, the third time duration is set to 1 minute. Next, the water storage electric control switch is turned off, so that the pure water prepared by the filtration system is discharged through the pure water discharge end, taking away the water stains or impurities that may remain in the pipe of the water purifier, thereby achieving the cleaning of the pipe of the water purifier.

[0090] When the second time period is longer than the third time period, it means that the time for the filtration system to prepare pure water is long enough, and the residual water stains or impurities such as dust in the pipes of the water purifier may have been cleaned when the pure water flows through the pipes of the water purifier, making the pipes of the water purifier cleaner. Finally, the water storage electric control switch is turned on to allow the pure water prepared by the filtration system to be stored in the pure water storage container through the pure water discharge end and the first one-way valve, so that the purity of the pure water in the pure water storage container is further improved.

[0091] The water purifier cleaning method proposed in this embodiment responds to the first emptying signal, controls the water inlet solenoid valve to open, the booster pump to start and the filtration system to start, and starts a preset timer, then obtains the second time length recorded by the timer in real time, and then when the second time length is less than the preset third time length, closes the water storage electric control switch to allow the pure water prepared by the filtration system to be discharged through the pure water discharge end, and finally when the second time length is greater than the third time length, opens the water storage electric control switch to allow the pure water prepared by the filtration system to be stored in the pure water storage container through the pure water discharge end and the first one-way valve, so that when the second time length is less than the preset third time length, the pure water prepared by the filtration system can flow through the pipes of the water purifier and take away the residual water stains or impurities such as dust that may exist in the pipes of the water purifier, thereby achieving the cleaning of the pipes of the water purifier. After cleaning, the pure water prepared by the filtration system is stored in the pure water storage container, so that the purity of the pure water stored in the pure water storage container is further improved.
