Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a method for controlling a recovery rate of a water purifier includes steps S100, S200, and S300.
And S100, acquiring the geographical position information of the area where the water purifier is located.
Specifically, the geographical location information is obtained by locating through a locating device arranged on the water purifier. The recovery rate of the water purifier is the proportion of the outflow pure water (or pure water) in the raw water after the reverse osmosis membrane filter element filters the inflow raw water in the water purifying process of the water purifier. And the waste water ratio of the water purifier is the ratio of the outflow concentrated water to the outflow purified water after the reverse osmosis membrane filter element filters the inflow raw water, so that the adjustment operation of the waste water ratio of the water purifier can be realized while the recovery rate of the water purifier is adjusted in the actual operation process.
It can be understood that the operation of adjusting the recovery rate of the water purifier can be performed when the water purifier is installed for the first time, or can be performed at any time after the installation of the water purifier is completed, and therefore, in order to ensure that the recovery rate of the water purifier is always matched with the current geographical position of the water purifier, the positioning operation of the positioning device should be performed in real time. It should be noted that the type of the positioning device is not exclusive, as long as the geographical location information of the area where the water purifier is located can be accurately sent to the host computer in real time for analysis processing. For example, in one embodiment, the Positioning device is a GPS (Global Positioning System) locator.
And S200, obtaining water quality information corresponding to the geographical position information according to the geographical position information and a preset water quality map.
Specifically, the preset water quality map stores water quality information of different areas. After the host of the water purifier obtains the geographical position information of the area where the water purifier is located, the geographical position information and a preset water quality map prestored in the host are directly subjected to matching analysis, and the water quality information of raw water (namely water before being treated by the water purifier) corresponding to the geographical position is directly obtained. The water quality information comprises water quality parameters, and the water quality parameters of the raw water in the area can be visually obtained through the water quality information so as to facilitate subsequent recovery rate adjustment operation according to the water quality parameters in the water quality information.
It should be noted that the parameters included in the water quality information are not exclusive, as long as the parameters can affect the water quality. For example, in one embodiment, the water quality information includes at least one of Total Dissolved Solids (TDS), Sludge Density Index (SDI), water temperature, hardness, alkalinity, and hydrogen ion concentration Index (PH). In particular, in one embodiment, the water quality information includes TDS, SDI, water temperature, hardness, alkalinity and PH value, i.e. the TDS, SDI, water temperature, hardness, alkalinity and PH value of the raw water in the area can be directly obtained according to the geographical position information sent by the position device.
It can be understood that, in an embodiment, please refer to fig. 2 in combination, the host of the water purifier has a wireless communicator such as a WiFi module, and the wireless communication operation between the water purifier and the external terminal device and/or the external server can be realized through the wireless communicator such as the WiFi module. When the water purifier runs, the geographical position information of the area can be sent to the external terminal device and/or the external server, and the external terminal device and/or the external server directly sends the water quality map (or the water quality information corresponding to the area) corresponding to the area to the host.
In other embodiments, the water quality information (i.e., the water quality map) corresponding to all the areas may be prestored in the host of the water purifier, and the host directly obtains the water quality information corresponding to the area where the water purifier is located during operation. Meanwhile, when the water quality map is updated, the user can transmit the updated water quality map to the water purifier through the external terminal equipment and/or the external server, so that the updating operation of the preset water quality map of the water purifier is realized.
And step S300, obtaining the system recovery rate matched with the water purifier according to the water quality information, and adjusting a recovery rate control device of the water purifier according to the system recovery rate.
Specifically, after the host computer obtains the corresponding water quality information according to the geographical position information of the water purifier, the host computer analyzes the water quality information according to the water quality parameters in the water quality information to obtain the system recovery rate which can be matched with the current water quality information. The system recovery rate required by the water purifier in the optimal operation state can be obtained, and then the recovery rate control device of the water purifier is adjusted according to the system recovery rate, so that the recovery rate control device operates in a state corresponding to the system recovery rate.
It can be understood that the type of recovery rate controlling means is not exclusive, in this embodiment, mainly realizes the regulation to the recovery rate of purifier through the thick water discharge after the reverse osmosis membrane that changes the purifier is handled, and in traditional purifier, the thick water branch road is provided with the waste water solenoid valve of corresponding model and carries out thick water control operation. Therefore, in a simpler embodiment, after the system recovery rate required by the current water purifier is obtained, the host of the water purifier pushes the system recovery rate to a user, and the user directly replaces the wastewater electromagnetic valve with the wastewater electromagnetic valve of the corresponding model.
In one embodiment, referring to fig. 3, step S200 includes step S210.
And step S210, acquiring season information, and acquiring corresponding water quality information according to the season information, the geographical position information and a preset water quality map.
Furthermore, because the water quality information of different areas is influenced by the season information, the water quality of the same area in different seasons can be distinguished, for example, the water temperature is higher in summer, and the viscosity of water is reduced; in winter, the water temperature is low, and the viscosity of the water is increased. Therefore, the water quality information also comprises season information, namely when the host machine matches the acquired geographical position information, corresponding water quality parameters exist in different seasons corresponding to the same geographical position information, and when subsequent analysis operation is carried out, the season information can be input by a user to obtain the water quality parameters corresponding to the region in the current season; or the host computer carries out intelligent analysis according to the current date to obtain the season information corresponding to the current date and finally obtain the water quality parameters corresponding to the region in the current season. That is, in this embodiment, the host can obtain the season information, and then obtain the corresponding water quality information according to the season information, the geographical location information, and the preset water quality map. It should be noted that the season information can be divided into four seasons of spring, summer, autumn and winter; in another embodiment, since spring seasons are similar, the season information may be classified into three types of spring and autumn, summer and winter. It can be understood that, in other embodiments, multiple sets of water quality parameters of the same geographical location and the same season may also be stored in the preset water quality map, and the host performs analysis operations such as average value calculation according to the multiple sets of water quality parameters during matching analysis to obtain a set of water quality parameters corresponding to the current season of the area.
In one embodiment, referring to fig. 4, step S200 includes step S220.
And step S220, acquiring season information and weather information of an area where the water purifier is located, and acquiring corresponding water quality information according to the season information, the weather information, the geographical position information and a preset water quality map.
Furthermore, the water quality parameters of the raw water are also influenced by the weather conditions, and therefore, the water quality information can also comprise weather information. In the preset water quality map, for the water quality parameters of different weather conditions stored in the same region and the same season, for example, the water quality parameters in summer of the X region comprise two sets of water quality parameters of rainwater weather and non-rainwater weather, when the host computer obtains the X region of the region where the water purifier is located according to the geographical position information and obtains summer season through intelligent analysis according to the date, the host computer can obtain the water quality parameters in the rainwater weather in summer of the X region according to the analysis of the rainwater weather input by the user. It is understood that in other embodiments, the weather information may also be obtained in other manners, for example, the host of the water purifier can communicate with an external terminal device (e.g., a mobile phone, a tablet, etc.), then read the weather condition information of the terminal device such as the mobile phone, and then obtain the final water quality parameter with the geographical location information, the seasonal information, the weather information, and the preset water quality map.
It should be noted that the type of the weather information is not limited to the rain weather in the above embodiment, and in other embodiments, various different season information such as snow weather and haze weather may be set according to the characteristics of the region or the characteristics of different seasons.

The first concentrated water branch 31 is a normally open branch, the second concentrated water branch 32 and the backflow branch 33 are alternately open branches, and when the first concentrated water branch 31 and the second concentrated water branch 32 are open and the backflow branch 33 is closed, a pulse working mode is adopted; when the first concentrated water branch 31 and the return branch 33 are opened and the second concentrated water branch 32 is closed, the two modes are controlled by two water inlet electromagnetic valves in a return working mode, and the system recovery rate is realized by the difference of the opening and closing time of the pulse mode and the return mode, namely, the water purifier is operated at different recovery rates by controlling the different opening time of the first water inlet electromagnetic valve and the second water inlet electromagnetic valve.
In one embodiment, the step of adjusting the recovery rate control device of the water purifier according to the system recovery rate comprises: and controlling a stepless regulating valve arranged on a concentrated water branch of the water purifier to operate in a corresponding gear according to the system recovery rate.

The stepless regulating valve 351 is an electromagnetic valve with a plurality of different flow gears, and the water purifier can be operated at different recovery rates by controlling the stepless regulating valve 351 to operate at different gears. In this embodiment, only one concentrate branch (i.e., the third concentrate branch 35) needs to be provided, and the stepless regulating valve 351 is provided on the concentrate branch, so that after the host analyzes the system recovery rate, the stepless regulating valve 351 is directly controlled to operate in a corresponding gear.

Since the waste solenoid valve 362 has a small hole besides an opening, the small hole defines different types of waste solenoid valves 362 (i.e. the flow rate of the waste valve). Therefore, when energized, the opening of the waste solenoid valve 362 is opened and the water volume will be large, achieving a flushing operation; when the power is off, only the small hole of the waste water solenoid valve 362 has water flowing through, and the water quantity is relatively reduced. The water inlet solenoid valve 361 is provided with only one opening, and when the water inlet solenoid valve is electrified, the opening is opened through an electromagnetic induction phenomenon, so that water can be discharged; when the power is cut off, the opening is closed, and water cannot pass through. Therefore, a water inlet solenoid valve 361 is further provided before the waste water solenoid valve 362 (i.e., at a position closer to the concentrate outlet of the reverse osmosis membrane cartridge), and the opening and closing operations of the concentrate branch 36 are realized by the water inlet solenoid valve 361.
