Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, if the existing water purifier system is not used for a period of time at intervals, the TDS value of the water purifying side of the water purifier system is increased due to the permeation mixing of purified water and concentrated water, and a user needs to open a tap each time to release a part of water, so that the water purifier system can be normally used, and the experience of the user can be reduced. Based on the above, the embodiment of the invention provides a control method, a control device and an electronic device of a water purifier system, which provide a system for regulating the pressure of purified water/concentrated water in an RO (Reverse Osmosis) membrane, so as to improve the TDS value of first cup water of a user.
For the sake of understanding the present embodiment, first, a detailed description will be given of a control method of a water purifier system disclosed in the present embodiment.
Embodiment one:
the embodiment of the invention provides a control method of a water purifier system, which can be applied to the water purifier system, wherein a reverse osmosis membrane filter element, a concentrated water valve and a concentrated water port of the water purifier system are sequentially connected, and the reverse osmosis membrane filter element, a water outlet valve, a normal temperature water valve and a normal temperature water port are sequentially connected.
In the actual use process of the reverse osmosis water purifier, when the machine is stopped for a period of time and then the tap is opened to discharge purified water, TDS can be increased (the problem of water ageing), mainly because water in the RO membrane filter element filter flask slowly permeates into the central tube through the membrane, the TDS of the stored water at the central tube is increased, and when a user opens the water purifier to receive purified water, the stored water at the central tube is mixed with the newly prepared purified water, so that the TDS value of the first cup of water is too high.
Based on the above description, referring to a flowchart of a control method of a water purifier system shown in fig. 1, the control method of the water purifier system includes the steps of:
step S102, filtering raw water of the water purifier system through a reverse osmosis membrane filter element to obtain purified water and concentrated water of the water purifier system.
The water purifier system is provided with a reverse osmosis membrane filter element, and the RO membrane is an artificial semipermeable membrane with certain characteristics and made of an analog biological semipermeable membrane, and is a core component of a reverse osmosis technology. The principle of reverse osmosis is to separate other substances from water under the action of osmotic pressure higher than that of solution according to the fact that the substances cannot permeate through a semipermeable membrane. The pore size of the reverse osmosis membrane is very small, so that dissolved salts, colloids, microorganisms, organic matters and the like in water can be effectively removed.
Therefore, the raw water of the water purifier system can be filtered through the reverse osmosis membrane filter element, so that the purified water and the concentrated water of the water purifier system are obtained. Wherein, the purified water is clean water obtained by filtering raw water, the concentrated water is waste water generated by filtering, and the water is unclean water.
Step S104, a concentrate valve is opened, and the concentrate is controlled to flow out through the concentrate port.
The concentrated water valve of the water purifier system is opened, so that the concentrated water flows out through the concentrated water port, and the concentrated water back pressure measurement of the reverse osmosis membrane filter element of the water purifier system can be released due to the outflow of the concentrated water.
Step S106, the water outlet valve is opened after the rich water valve is opened for a preset first time interval.
The water outlet valve can be controlled to be opened and closed by the water purifier system, and after the water concentration valve is opened for a preset first time interval (the first time interval can be 3-5 minutes), the water outlet valve can be opened, and the back pressure of the concentrated water of the reverse osmosis membrane filter element of the water purifier system can be considered to be completely released.
Step S108, a normal-temperature water valve is opened, and purified water is controlled to flow out through the normal-temperature water port.
The normal temperature water valve can be controlled to be opened and closed by the water purifier system, and also can be opened manually by a user. Wherein, the time of opening at the dense water valve does not reach first time interval, and the outlet valve does not open, if the normal atmospheric temperature water valve is opened by hand this moment, the water purification also can not flow through the normal atmospheric temperature mouth of a river.
After the first time interval is started, the water outlet valve and the normal-temperature water valve are started, the side pressure of purified water can be communicated with the atmosphere, accumulated water on the purified water side in the reverse osmosis membrane filter element flows to the concentrated water due to osmotic pressure, and the flowing speed of salt ions is slower, so that purified water and concentrated water can be separated.
According to the control method of the water purifier system, provided by the embodiment of the invention, the concentrated water of the water purifier system is controlled to flow out through the concentrated water port by opening the concentrated water valve; opening a water outlet valve after a thick water valve is opened for a preset first time interval; and controlling purified water of the water purifier system to flow out through the normal-temperature water port by opening the normal-temperature water valve. In this mode, can let out the dense water back pressure of measuring of reverse osmosis membrane filter core of purifier system through opening the dense water valve, open outlet valve and normal atmospheric temperature water valve after the dense water valve opens first time interval, can be with water purification lateral pressure and atmosphere intercommunication, the interior water purification lateral ponding of reverse osmosis membrane filter core is owing to osmotic pressure flow to dense water survey, and salt ion velocity of flow is comparatively slow, consequently can separate water purification and dense water, the user also can directly use the water purification, need not open the tap and put away a part of water, can improve the TDS value of the first cup of water of user, promote user's experience and feel.
Embodiment two:
the embodiment of the invention provides another control method of a water purifier system, which is executed on the basis of the method provided by the embodiment; referring to a flowchart of another control method of a water purifier system shown in fig. 2, the control method of the water purifier system includes the steps of:
step S202, filtering raw water of the water purifier system through a reverse osmosis membrane filter element to obtain purified water and concentrated water of the water purifier system.
Referring to a schematic diagram of a water purifier system shown in fig. 3, key components of the water purifier system are as follows: the device comprises a pressure reducing valve 1-2, a composite filter element, a water inlet electromagnetic valve 1-2, a one-way valve 1-4, an air pump, a booster pump, an RO membrane filter element, a concentrated water valve, a micro bubble water valve, a water outlet valve, a hot water valve, an RO normal temperature water valve, a water pump, a flowmeter, a heating pipe and the like; and the composite filter element is divided into a front carbon treatment area and a rear carbon treatment area.
And step S204, when the stop time of the water purifier system reaches a preset time threshold, starting a concentrate valve, and controlling the concentrate to flow out through the concentrate port.
The water purifier system can flow out concentrated water through the concentrated water branch, as shown in fig. 3, raw water enters the pressure reducing valve through the water inlet, is subjected to rough filtration through the composite filter element, passes through the water inlet electromagnetic valve 1, the booster pump and the water inlet electromagnetic valve 2 to the RO membrane filter element, and the generated concentrated water is discharged from the concentrated water port through the concentrated water valve;
in addition, the water purifier system can flow out normal-temperature purified water through the RO normal-temperature water branch, as shown in fig. 3, a user can click a human-computer interaction module (intelligent tap) to take an RO normal-temperature water button, a booster pump is started, the water inlet electromagnetic valves 1-2 and the RO normal-temperature water valve are opened, raw water enters the pressure reducing valve through the water inlet and is subjected to rough filtration through the composite filter element, and is filtered in the RO membrane filter element through the water inlet electromagnetic valve 1, the booster pump and the water inlet electromagnetic valve 2, and the prepared purified water returns to a rear carbon area in the composite filter element for further treatment and flows out through the RO normal-temperature water valve to obtain RO normal-temperature water.
Specifically, reference may be made to a schematic diagram of a first method of TDS adjustment of a cup of water shown in fig. 4, which defaults to an automatic start-up procedure, which is automatically started when the net dispenser stops operating for a hours (i.e., a preset time threshold). Wherein a can be set by a human-machine interaction module (smart tap) and defaulting can be 0.5-2 hours, for example: the water purifier system comprises a man-machine interaction module, and the time threshold value can be determined through the man-machine interaction module in response to the setting operation aiming at the time threshold value. As shown in fig. 4, the concentrate valve is opened after the start of the process, and the RO concentrate side backpressure is relieved.
Step S206, opening the water outlet valve after the rich water valve is opened for a preset first time interval.
As shown in fig. 4, the RO room temperature water valve is opened for B minutes (i.e., the first time interval, which may be 3-5 minutes).
Step S208, a normal-temperature water valve is opened, and purified water is controlled to flow out through the normal-temperature water port.
After normal temperature water valve and outlet valve all open, can make RO water purification side and atmosphere intercommunication, owing to atmospheric pressure balance, the hydrone is because osmotic pressure is measured from water purification side to dense water, and hydrone velocity of flow is greater than salt ion velocity of flow far away to make water purification side deposit water constantly reduce, and salt ion concentration hardly increases, thereby after the machine makes water again, first cup water TDS reduces.
In addition, the method further comprises the following steps: and closing the rich water valve and the water outlet valve after the rich water valve is opened for a preset second time interval. As shown in fig. 4, after C minutes (i.e., the second time interval may be 120-360 minutes), the concentrate valve, the RO normal temperature valve, and the outlet valve are closed, and the adjustment process is terminated.
According to the method provided by the embodiment of the invention, the back pressure of the concentrated water in the RO membrane is relieved by opening the concentrated water valve, the RO normal-temperature water valve and the water outlet valve are opened, the water purification side pressure is communicated with the atmosphere, the accumulated water on the water purification side in the membrane flows to the concentrated water by virtue of the osmotic pressure, and the flowing speed of salt ions is slower, so that the aim of improving the TDS of the first cup of water of a user is fulfilled. In the mode, a pure water/concentrated water pressure regulating system in the RO membrane is provided, so that the TDS value of a first cup of water of a user is improved; the tap can be drunk immediately after being opened without waiting for empty.
In addition, in the existing water purifier system, in order to store for a long time, the RO membrane is added with protective agents such as glycerin, surfactant and the like, and the protective agents have high concentration and can be washed clean only after a long time. The RO membrane is generally connected with post carbon for absorbing peculiar smell and improving taste. These washed out organic protective agents are adsorbed by the post-carbon, thereby reducing the post-carbon adsorption performance and adsorption life.
In order to solve the above technical problems, as shown in fig. 3, the water inlet, the composite filter element, the booster pump and the reverse osmosis membrane filter element of the water purifier system are sequentially connected, and the rear carbon, the first one-way valve (i.e., the one-way valve 3 in fig. 3) and the water outlet valve of the composite filter element are sequentially connected. The method further comprises the following steps: opening a water outlet valve and a normal-temperature water valve to control purified water to flow out through a normal-temperature water port; and based on the fact that the water pressure at the water outlet valve side is smaller than the water pressure at the composite filter element side, the control of the purified water does not flow into the rear carbon of the composite filter element through the first one-way valve.
Specifically, the water outlet valve and the normal-temperature water valve can be opened through the human-computer interaction module of the water purifier system in response to the confirmation operation of the flushing button of the water purifier system.
Referring to the schematic diagram of a new machine and a new membrane cleaning control method shown in fig. 5, when a new filter element/new machine is installed for the first time, a new machine/new membrane cleaning button of a man-machine interaction module of a water purifier system can be clicked, and a signal is sent to a control module of the water purifier system, so that components in the new machine/new membrane cleaning module are controlled. Raw water enters the pressure reducing valve through the water inlet and is subjected to coarse filtration through the composite filter element, and is filtered in the RO membrane filter element through the water inlet electromagnetic valve 1, the booster pump and the water inlet electromagnetic valve 2. At this time, the water outlet valve and the RO normal temperature water valve are opened, the waterway is directly communicated with the RO normal temperature water port, and as the lateral pressure value of the water outlet valve is smaller than the lateral pressure of the one-way valve 3 of the composite filter element, purified water can not reach the rear carbon area of the composite filter element through the one-way valve 3, and the purified water directly flows out from the RO normal temperature water port through the RO normal temperature water valve by the water outlet valve, and the whole flushing time D is generally 30 to 300 minutes. After the flushing time is finished, the water inlet electromagnetic valves 1-2, the RO normal temperature water valve, the water outlet valve and the booster pump are closed, and the flushing is finished.
According to the method provided by the embodiment of the invention, the water outlet valve is connected in parallel with the rear carbon in the composite filter element, and as the side pressure of the water outlet valve is smaller than the pressure of the rear carbon, the purified water prepared by RO directly flows to the RO normal-temperature water meter from the water outlet valve, so that organic pollutants in the process of flushing a new membrane do not pass through the rear carbon. In this way, a post-carbon protection system is provided to realize that the post-carbon is not used when a new machine or a new RO membrane is washed, solve the problem that the post-carbon is polluted by the new RO membrane, promote the adsorption performance of the post-carbon and prolong the service life of the post-carbon.
In addition, in the conventional water purifier system, for a general water purifier having an instant heating function, since the filtered water amount of the water purifier is much larger than the instant heating water amount, a water tank for storing purified water is generally designed to adjust the water amount entering the instant heating device. The long-term use of the water tank can grow a large amount of bacteria, has potential safety hazards to the health of long-term drinkers, and the water tank occupies a volume.
In order to solve the above technical problem, as shown in fig. 3, the water outlet valve, the water pump, the heating pipe, the hot water valve and the hot water port are sequentially connected, and the method further includes: pumping purified water through a water pump; the purified water is heated by the heating pipe, and the heated purified water is controlled to flow out through the hot water valve and the hot water port.

The user can click a man-machine interaction module (intelligent tap) to take RO hot water button, the booster pump is started, the water inlet electromagnetic valves 1-2 and the hot water valve are opened, raw water enters the pressure reducing valve through the water inlet and is coarsely filtered by the composite filter element, and then is filtered in the RO membrane filter element through the water inlet electromagnetic valve 1, the booster pump and the water inlet electromagnetic valve 2. Because the flow before and after the water suction pump is inconsistent, the front side of the water suction pump has the pressure before the water suction pump, and the pressure value at the position is larger than the pressure value at the position of the one-way valve 4, so that part of the purified water flows back to the front of the booster pump from the rear carbon area of the composite filter element, and the other part of the purified water returns to the rear carbon area in the composite filter element for further treatment, and flows out from the hot water port through the hot water valve after being heated by the water suction pump, the flowmeter and the heating pipe, thereby obtaining hot water.
As shown in fig. 3, the flowmeter, the heating pipe and the hot water valve of the water purifier system are sequentially connected, and the method further includes: and controlling the working power of the water pump through the flowmeter.
In order to obtain hot water with different temperatures, the working power of the water pump can be controlled through the flowmeter, so that the flow of water entering the heating pipe is controlled, and different temperatures are realized; or the temperature of the discharged water is regulated by regulating the heating power of the heating pipe.
The embodiment of the invention provides the method, which provides a heating system without a water tank, and controls the water flow entering a heating device through the return flow of purified water.

Prolonging the service life and the performance of the post carbon and RO filter element. In this way, a backflow branch and a one-way valve 4 are newly added in front of a rear carbon area in the composite filter element. The returned purified water directly returns to the front of the booster pump without carbon after being put in the back, thereby achieving the purpose of adjusting the water flow entering the hot water branch.
In addition, in the existing water purifier system, water from the conventional reverse osmosis water purifier is normal-temperature water, when a user needs to use hot water, the water from the reverse osmosis water purifier needs to be connected to be boiled independently or additionally connected with a pipeline mechanism for hot water use, namely the conventional reverse osmosis water purifier has single function, only has purified water or purified water, and is difficult to meet the requirements of multiple scenes/multiple uses of users.
In order to solve the above technical problem, as shown in fig. 3, a booster pump, a third check valve (check valve 2 in fig. 3), a gas mixing tank and a gas bubble water port of the water purifier system are sequentially connected, and the method further includes: opening a third one-way valve to control purified water to enter the gas mixing tank so as to obtain bubble water; controlling bubble water to flow out through the bubble water gap.
