By adopting the method, the first water outlet of the water purifying system is communicated with the reflux inlet of the water purifying system, so that the water returning sterilization of the water purifying system can be conveniently carried out through the reflux tube group 20 and the water purifying tube group 10 under the condition that the water outlet piece 30 does not outlet water, and the sterilization and disinfection effect of the water purifying system is improved.
In this embodiment, the control of the first water outlet of the water purification system to communicate with the return inlet of the water purification system or the second water inlet of the water purification system according to the habit of the user and/or the life decay of the filter element assembly 12 of the water purification system comprises the control of the first water outlet to disconnect from the return inlet when in a peak period of user water consumption, and the control of the first water outlet to disconnect from and connect with the return inlet when in a low peak period of user water consumption, wherein the water consumption flow of the peak period of user water consumption is greater than the water consumption flow of the low peak period of user water consumption, and/or the water consumption frequency of the peak period of user water consumption is greater than the water consumption frequency of the low peak period of user water consumption. Therefore, the influence of the backwater sterilization and disinfection process on the normal water taking of the user can be facilitated, and the normal use of the user is ensured.
Specifically, the first water outlet of the water purification system is controlled to be communicated with the backflow inlet of the water purification system or the second water inlet of the water purification system according to the water consumption habit of a user and/or the service life attenuation condition of the filter element assembly 12 of the water purification system, and the first water outlet is controlled to be disconnected with the backflow inlet when the water consumption habit of the user is in a preset time period before the water consumption peak time period of the user. Thus, the water quality effect of the user when taking the first cup of water can be conveniently ensured.
In the embodiment, according to the water habit of a user and/or the service life attenuation condition of the filter element assembly 12 of the water purification system, the control of the first water outlet of the water purification system to be communicated with the backflow inlet of the water purification system or the second water inlet of the water purification system comprises the steps of controlling the time between the first water outlet and the backflow inlet to be communicated with the first water outlet and the backflow inlet to be a first preset time length when the service life percentage of the filter element assembly 12 is smaller than or equal to a preset service life percentage, and controlling the time between the first water outlet and the backflow inlet to be communicated with the first water outlet and the backflow inlet to be a second preset time length when the service life percentage of the filter element assembly 12 is larger than the preset service life percentage, wherein the first preset time length is smaller than the second preset time length. By adopting the method, the dirt degree of the filter element assembly 12 can be conveniently and well adapted to the sterilization effect of the filter element assembly 12, so that the water outlet quality of the water outlet piece 30 is ensured.
Specifically, the lifetime corresponds to a unit of time, and in particular, the lifetime may be measured in hours, days, or minutes.
In the embodiment, the water purifying method further comprises the steps of acquiring the water quality condition of the pipeline between the filter element assembly 12 of the water purifying system and the sterilizing piece 13 of the water purifying system, and controlling the sterilizing degree of the sterilizing piece 13 of the water purifying system according to the water quality condition of the pipeline between the filter element assembly 12 of the water purifying system and the sterilizing piece 13 of the water purifying system. By adopting the method, the water purification system can be conveniently and better sterilized and disinfected in an adaptive manner under actual conditions, so that a sterilization effect is better achieved. Specifically, the sterilization degree of the sterilization member 13 can be controlled by controlling the operation power of the sterilization member 13. The water quality condition can be measured by detecting the TDS value.
The working frequency and the working time of the water purification backflow can be intelligently adjusted according to the use habit of a user and the dirt degree of the filter element. If the pure water backflow is performed in the daytime, the working time period cannot be too long, and if the pure water backflow is performed in the evening, the working time period can be properly prolonged. The working frequency and the working time of pure water backflow can be adjusted according to the use condition and the pollution degree of the filter element assembly 12, for example, the working frequency of pure water backflow can be lower when a new filter element is used, the working time can be shorter, for example, the working frequency of pure water backflow can be improved when the pollution degree of the filter element is serious after the filter element is used for a period of time, and the working time can be prolonged.
The electric control board and the complete machine control system can collect water taking use habits of users, such as water taking frequency and time period, and intelligently set the working time period and the working frequency of pure water backflow according to the water taking use habits of the users, so that the water quality drunk by the users can be ensured to be in a fresh and pollution-free state at any time while the interference to water taking of the users is avoided.
Specifically, the working frequency can be set to be 1-2 hours in the daytime, meanwhile, the water taking peak period of 8:00-9:30, 12:00-13:30 and 18:00-19:30 is avoided, and the preset working time is set to be 1-5 minutes. The operating frequency may be set to 2 to 3 hours at night and the preset operating time period to 5 to 10 minutes.
Specifically, according to the service life percentage of the filter element or the attenuation percentage of the water flow of the filter element, the pollution degree of the filter element can be quantitatively evaluated, and different working time periods can be correspondingly set. According to the used water quantity of the filter element and the preset total water quantity of the filter element, the calculated service life percentage of the filter element is set to be different, namely, when the used service life percentage of the filter element assembly 12 is in the range of 0% -30%, the preset service time of pure water backflow each time can be set to be 1-3 minutes, when the used service life percentage of the filter element assembly 12 is in the range of 30% -70%, the preset service time of pure water backflow each time can be set to be 3-6 minutes, and when the used service life percentage of the filter element assembly 12 is above 70%, the preset service time of pure water backflow each time can be set to be 6-12 minutes. Similarly, the attenuation percentage of the water flow of the filter element can be correspondingly calculated according to the initial water flow of the filter element, the preset minimum water flow of the filter element and the real-time water flow of the filter element, and different working time lengths are correspondingly set by using the attenuation percentage of the water flow of the filter element (the setting mode is the same as the above).
Specifically, when the user is in a sleep state at night, the probability of the user getting water is generally low. While on the daytime, the water consumption probability of the user is relatively high. The operating frequency may be set to 1 to 2 hours during the day and the preset time period to 1 to 5 minutes. Further, the pure water reflux process is controlled to be started 1 to 60 minutes before the user takes water. For example, if the user takes water at 1 pm, the water draining process is controlled to be started before the water draining process is started, so that the water draining process is finished when the user takes water, and the water quality is in a fresh and pollution-free state.
When the electric control board and the complete machine control system intermittently send an opening signal and a closing signal to the reflux electromagnetic valve, the interval time between the current reflux and the next reflux is not fixed, for example, the interval time can be in a gradually increasing trend. In a specific application example, the user takes water more frequently in the daytime, and the interval time can be gradually increased, so that the influence of the circulation mode on the normal water taking of the user is avoided.
In summary, the periodic or intermittent control of the backflow solenoid valve for drainage more accords with the actual needs of users and the working state of the water purification system, is beneficial to energy saving and avoids idle work. And the user participates in setting parameters (period and first preset duration), instead of fixing the parameters, so that the method is more intelligent and the use experience of the user is further improved.
In one possible implementation manner, the electric control board (corresponding to the control piece) and the complete machine control system are also used for acquiring water use time information of a user, and determining the working frequency and the working time length of the reflux electromagnetic valve according to the water use time information so that the reflux electromagnetic valve completes work before the user takes water.
In order to acquire the water consumption time information of the user, an acquisition chip can be arranged in the electric control board to automatically acquire the water consumption frequency and the time period of the user, and the information is sent to the electric control board and the whole machine control system. Therefore, the water consumption time period of a user and the water production time period of the water purification system are avoided in the process of discharging the pure water, and the water purification system is prevented from waterway interference caused when multiple modes are executed simultaneously. And the working frequency and the working time of the reflux electromagnetic valve are automatically set according to the water habit of the user, so that the water quality drunk by the user can be ensured to be in a fresh and pollution-free state at any time.
In one possible implementation, the electronic control board and the complete machine control system are also used for sending a closing signal to the return electromagnetic valve when the user is monitored to take water.
Specifically, whether the user has water taking demands can be monitored by collecting user operation signals, and the signals for taking water by the user are fed back to the electric control board and the complete machine control system. The electric control board and the complete machine control system can send a closing signal to the reflux electromagnetic valve after receiving a signal of water taking by a user, and the reflux is stopped. Therefore, the user can take water normally immediately, and the water taking of the user cannot be disturbed. And can be as described in the above-mentioned realization mode, according to user's water habit, make the drainage process avoid the water intaking period of user, when guaranteeing that user's water safety that drinks does not have the pollution, avoid causing the interference to user's water intaking.
From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects that the sterilization effect on the waterway of the water purification branch can be achieved by arranging the sterilization member in front of the water outlet member of the water purification branch of the whole machine, and the sterility of the outlet water of the outlet faucet is ensured. Meanwhile, a pure water reflux waterway is added behind the sterilizing piece and is communicated to the front filter element, when the whole machine is in a water making stopping mode, the whole machine control system can control pure water to flow back to the front filter element, and the filtering assembly is circularly diluted, so that the bacteriostatic effect of the pipeline is achieved when the water quality effect of the first cup of water is improved.
