step 302, acquiring the water storage state of a water inlet pipeline or a water outlet pipeline;
and step 304, controlling the conduction of the water passage pipeline based on the water inlet pipeline or the water outlet pipeline being in a water shortage state.
In this embodiment, the water supply system is provided with a water inlet pipe, a water outlet pipe, a first purifying device, a water passage pipe, a water storage state detecting device, and a flow detecting device. The water inlet of the first purifying device is connected with the water inlet pipeline, the first water outlet of the first purifying device is connected with the first end of the water outlet pipeline, the second water outlet of the first purifying device is connected with the water draining pipeline, the water storage state detecting device is arranged on the water inlet pipeline or the water outlet pipeline, and the flow detecting device is arranged between the first end of the water passage pipeline and the first water outlet of the first purifying device.

step 406, obtaining the water storage state of the water inlet pipeline or the water outlet pipeline;
in step 408, the water passage is controlled to be blocked based on whether the water inlet pipeline or the water outlet pipeline is in a water state.
In this embodiment, the water in the water inlet pipe or the water outlet pipe is detected by controlling the water storage state detecting device to obtain the water storage state, and if the water storage state detecting device displays that a signal of the water storage state is sent, the water passage pipe is controlled to be cut off. In the embodiment of the invention, the control of the cut-off of the water passage pipeline is realized by controlling the water storage state detection device, so that the mixing of the water used by a user and the concentrated water caused by the fact that the concentrated water generated by the first purification device flows into the water outlet pipeline from the water discharge pipeline through the water passage pipeline is avoided, the water supply system is ensured to provide safer and more sanitary water for the user, and the safety and the reliability of the whole water supply system are improved.
In any of the foregoing embodiments, the controlling the conduction of the water passage specifically includes: the first valve body, the second valve body and the booster pump of the water supply system are controlled to be opened so as to conduct the water communication pipeline; the control water passage pipeline is cut off, specifically comprises: the first valve body, the second valve body and the booster pump of the water supply system are controlled to be closed so as to cut off the water passage.
In this embodiment, the water in the water inlet pipe or the water outlet pipe is detected by controlling the water storage state detecting means, and two water storage states are obtained. Under the condition, when the water storage state detection device displays a signal of sending out a water shortage state, the first valve body and the second valve body of the water supply system are controlled to be opened, and the booster pump is also controlled to be opened, so that a water inlet passage from a water supply source port, a water inlet pipeline, a first purification device, a water outlet pipeline, a flow detection device and a water passage to a concentrated water port is formed, and the conduction of the water passage is controlled; under another condition, the water storage state detection device displays a signal of water state, controls the first valve body and the second valve body of the water supply system to be closed, and simultaneously controls the booster pump to be closed, thereby blocking the formation of a water inlet passage from the water supply source port, the water inlet pipeline, the first purification device, the water outlet pipeline and the flow detection device to the water passage, and realizing the control of the water passage to be cut off. In the embodiment of the invention, the rationality of the use of the water supply system is realized by controlling the on-off of the water passage pipeline, and the accuracy of the control of the water supply system is improved.
It should be noted that, the embodiment of the invention is a brand new flow meter control system, the water system takes the water shortage situation around the flow meter as a judging condition, a brand new water shortage mode is started, the system is smoothly fed by combining the full-through water inlet waterway at the rear end under the mode, timely water supplement is realized, the system is never deficient, the realization of the system is irrelevant to the operation of a user, and the water system can normally feed water no matter whether a tap is opened or not, so that various practical problems of water shortage, restarting and the like of the new flow meter control system can be effectively solved.
In a third embodiment, fig. 5 is a schematic flow chart of a water supply control method according to an embodiment of the present invention, where the water supply control method includes:
step 502, obtaining the water storage state of a water inlet pipeline or a water outlet pipeline;
step 504, controlling the water passage to be conducted based on the water inlet pipeline or the water outlet pipeline being in a water shortage state;
step 506, obtaining the water storage state of the water inlet pipeline or the water outlet pipeline;
step 508, controlling the water passage to be cut off based on whether the water inlet pipeline or the water outlet pipeline is in a water state;
and 510, controlling the first valve body and the booster pump of the water supply system to be opened based on the water flow signal detected by the flow detection device.
In this embodiment, the flow detection device detects a water flow signal, which indicates that the user needs water, and then controls the first valve body of the water supply system to open to allow water to flow in from the water inlet pipeline, and controls the booster pump to open while controlling the first valve body to open, so as to perform pressure treatment on the water entering the water inlet pipeline, thereby enabling the water to smoothly flow into the water outlet pipeline for the user to use. In the embodiment of the invention, the water flow signal is detected by the flow detection device, so that the first valve body and the booster pump of the water supply system are controlled to be started, the reasonable use of the water supply system by a user is ensured, and the accuracy of the water supply system is improved.
In a fourth embodiment, fig. 6 is a schematic flow chart of a water supply control method according to an embodiment of the present invention, wherein the water supply control method includes:
step 602, obtaining the water storage state of a water inlet pipeline or a water outlet pipeline;
step 604, controlling the water passage to be conducted based on the water inlet pipeline or the water outlet pipeline being in a water shortage state;
step 606, obtaining the water storage state of the water inlet pipeline or the water outlet pipeline;
step 608, controlling the water passage to cut off based on whether the water inlet pipeline or the water outlet pipeline is in a water state;
and step 610, controlling the first valve body of the water supply system and the booster pump to be closed based on the fact that the flow detection device does not detect the water flow signal.
In this embodiment, the detection means does not detect a water flow signal, indicating that the user does not need water or that water is complete, the first valve body of the water supply system and the booster pump are controlled to be closed. In the embodiment of the invention, the first valve body is controlled to be closed, so that water of a water supply source stops continuously entering the water inlet pipeline, meanwhile, the booster pump of the water supply system is closed, the water of the water supply system is not pressurized any more, and the situation that the flow detection device mistakenly detects a water flow signal due to the flow of water caused by the pressurization of residual water remained in the water supply system is prevented, so that the water supply system is restarted, and the control process of the water supply system is out of control. Therefore, the flow detection device does not detect a water flow signal, so that the first valve body and the booster pump of the water supply system are closed, and the reliability and the accuracy of the control process of the whole water supply system are greatly improved.
In the fifth embodiment, the core of the novel flow meter control system of the water purifier is a flow meter (i.e. a flow detection device), and the precondition of the output signal of the flow meter is water flow, that is, whether the water purifier is started or not is determined by judging the water flow. In the daily use, the water purifier always encounters the condition of lack of water, and in this case, no water flow passes through the flowmeter position, so that no effective signal can be sent, and under the condition that the water inlet valve does not receive a signal and the water tap is closed, even if the water source is normal, the water supply system can not enter water, and a dead cycle is formed. Although the water inlet valve can be opened by electric control and the output signal of the water level sensor arranged at the forefront end, in this case, a user is required to actively open the water tap to ensure that the water inlet of the system smoothly reaches the flowmeter at the tail end, so that the realization condition is various, and the use cost of the user is greatly increased.
Therefore, the novel flowmeter control system is updated, and besides the parts such as the filter element and the like which are common in the related technology, the key core part of the novel flowmeter control system is a sensor for judging whether the water at the flowmeter is deficient or not, and the sensor can be a water level sensor, a water level capacitance patch, a water level probe or a low-voltage switch and the like. The sensor can provide a water shortage signal for the whole machine, so that the water supply system enters a water shortage mode, and the water shortage is possibly caused by tap water shortage or water shortage at the position of the flowmeter. In addition, the invention arranges a branch at the rear end of the flowmeter to connect a water inlet electromagnetic valve (i.e. the second valve body) to the rear end of the waste water valve or the waste water plug (i.e. the third valve body), the branch is called a water passage branch (i.e. a water passage), the design of the branch can ensure that no matter whether the rear-end tap (i.e. the water outlet device) is opened, a passage which can ensure the smooth water inlet of the system is provided, the water inlet electromagnetic valve (i.e. the first valve body) of the water inlet pipe is closed under normal condition, the pure water port is separated from the concentrated water port, and the system works normally. In the "water shortage mode", the water inlet electromagnetic valve (i.e. the second valve body) of the passage is opened, so that the rear end of the flowmeter is communicated with the concentrated water port to form a pressureless water inlet passage, wherein the specific water inlet passage of the flow sensor is "water inlet end (water supply source) -front filter element (i.e. the second purifying device) -water pump (i.e. the booster pump) -RO membrane (i.e. the first purifying device) -flowmeter-water-through branch-concentrated water port". The system designs an automatic judging water shortage mode and a water-through branch, and solves the problem that the flowmeter can not be started normally under various water shortage, water interruption and first use conditions.
To better illustrate the specific application form of the present invention, the present invention provides an embodiment specifically employing a water level sensor, a capacitive patch sensor, a water level capacitive patch or a low voltage switching device as the water storage state detecting device.
In the first case, fig. 7 shows a schematic flow chart of a control method of a water supply system according to an embodiment of the present invention, based on using a water level sensor as a water storage state detection device, where the control method of the water supply system includes:
step 702, acquiring a water level signal detected by a water level sensor;
step 704, judging whether the water level signal is a water shortage signal; if yes, go to step 706, if no, go to step 718;
step 706, entering "water shortage mode";
step 708, opening a water inlet electromagnetic valve of the water inlet pipeline;
step 710, opening a water inlet electromagnetic valve of the water passage branch;
step 712, acquiring a water level signal detected by a water level sensor;
step 714, determining whether the water level signal is a no water shortage signal; if yes, go to step 716, if no, go to step 706;
step 716, turning off the "water shortage mode";
step 718, water can be taken normally.
In this embodiment, the core of the novel flow meter control system is constituted by: the front PP cotton and front carbon rod integrated filter element, a water inlet electromagnetic valve, a booster pump, an RO membrane, a waste water valve, rear active carbon, a water level sensor, a flowmeter, a water-through branch, a tap and the like. The water level sensor is positioned around the flowmeter and used for detecting whether the flowmeter lacks water, when the flowmeter does not lack water around, the system can normally operate, and water is pushed out through the pressure maintaining function of the one-way valve every time water taking, so that the machine is started. When water is deficient around the flowmeter, the system enters a water deficiency mode, in the mode, a water inlet electromagnetic valve of a water inlet pipeline of the system is opened, a water inlet electromagnetic valve of a water passage branch is opened, a waterway of a water inlet end-front PP cotton and front carbon rod integrated filter element-water inlet electromagnetic valve-water pump-RO membrane-flowmeter-water passage branch-concentrated water port is formed, the system waits for water to enter the flowmeter, once the water level sensor detects water around the flowmeter again, the water deficiency mode is closed, the water inlet electromagnetic valve is closed, a water inlet passage is closed, a one-way valve is used for maintaining pressure, and the system is recovered to normal conditions.
In the second case, based on the adoption of the patch sensor as the water storage state detection device, namely, the core structure of the novel flowmeter control system is as follows: the front PP cotton and front carbon rod integrated filter element, a water inlet electromagnetic valve, a booster pump, an RO membrane, a waste water valve, rear active carbon, a patch sensor, a flowmeter, a water-through branch, a tap and the like. The water supply control method of the system in this embodiment is the same as that in the first case described above, that is, based on the use of a water level sensor as the water storage state detection means. However, a capacitor patch sensor is used for judging whether water is lacking around the flowmeter, and the capacitance value generated by water or no water in the pipeline is different, so that the system outputs different signals.
In the third case, the low-voltage switch is adopted as the water storage state detection device, namely the core structure of the novel flowmeter control system is as follows: the low-voltage switch, the preposed PP cotton and preposed carbon rod integrated filter element, the water inlet electromagnetic valve, the booster pump, the RO membrane, the waste water valve, the postpositive active carbon, the flowmeter, the water-through branch, the tap and the like. The water supply control method of the system in this embodiment is the same as that in the first and second cases described above, that is, the embodiment based on the use of the water level sensor, the patch sensor as the water storage state detection means. However, when the low-voltage switch is used for judging whether the pipeline is in a water cut-off state or not and enabling the water purifier to start a water cut-off mode, the signal of the low-voltage switch can only judge whether the pipeline source is in water cut-off or not, and the water level condition around the flowmeter cannot be guaranteed. The reason for this is that in the case where the tap water is not shut down, the water shortage around the flowmeter still needs to trigger the water shortage mode due to bubbles or the like, and the low-voltage switch cannot trigger the water shortage mode in this case. This embodiment is therefore limited in applicable conditions compared to the first and second embodiments, but still has room for availability due to the relatively mature and low cost low voltage switch applications.
The invention provides a prompt of the water shortage state of the novel flowmeter, a control method under a 'water shortage mode' and a new water path of the water-through branch, and the novel flowmeter control system is reasonably used in the water purifier by cooperation of the novel flowmeter control system and the new water path, so that a plurality of problems in the related art caused by using the water purifier can be solved.
