Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Fig. 1 is a schematic structural diagram of the household water purifying device in the embodiment.

Referring to fig. 1, the household water purifying apparatus includes a dual-channel desalination assembly 100 and a pipeline system 200.

As shown in FIG. 1, the dual-channel desalination assembly 100 comprises a water inlet 110, a first water outlet 120 and a second water outlet 130, wherein water flows into the dual-channel desalination assembly 100 from the water inlet 110 for purification treatment, and treated pure water and wastewater are discharged through the first water outlet 120 and the second water outlet 130, respectively.

Specifically, the pipe system 200 includes a first pipe 210, a second pipe 220 and a third pipe 230, the first pipe 210 is connected to the water inlet 110, and the first pipe 210 is used for supplying water to the water inlet 110. The second line 220 is used for outputting pure water treated by the dual-channel desalination assembly 100, and the third line 230 is used for outputting wastewater treated by the dual-channel desalination assembly 100.

For example, the second pipeline 220 can be switchably connected to the first water outlet 120/the second water outlet 130, and the third pipeline 230 can be switchably connected to the second water outlet 130/the first water outlet 120, that is, the second pipeline 220 can be connected to the first water outlet 120, and the third pipeline 230 is connected to the second water outlet 130; or the second pipeline 220 is connected with the second water outlet 130, and the third pipeline 230 is connected with the first water outlet 120.

During the operation of the household water purifier, the operation condition of the dual-channel desalination assembly 100 is monitored, for example, the operation state information of the dual-channel desalination assembly 100, such as the water purification duration of the dual-channel desalination assembly 100, the accumulated electric quantity of the water purification operation of the dual-channel desalination assembly 100, and the like, is counted. When the operating condition of the dual-channel desalination assembly 100 reaches a predetermined condition, for example, the water purification treatment time of the dual-channel desalination assembly 100 reaches a predetermined time, the electrodes of the dual-channel desalination assembly 100 are switched, that is, the polarities of the positive and negative electrodes of the dual-channel desalination assembly 100 are switched, the water flowing in from the water inlet 110 performs a back-flushing on the dual-channel desalination assembly 100, and the generated wastewater is discharged through the first water outlet 120 or the second water outlet 130 and then flows to the third pipeline 230.

By reverse-polar flushing the dual-flow desalination assembly 100, the scaling risk of the dual-flow desalination assembly 100 is reduced, the service life of the dual-flow desalination assembly 100 is prolonged, and the quality of the produced pure water is improved.

In some embodiments, the piping system 200 further includes a first waterway switch 240 and a second waterway switch 250, wherein the first waterway switch 240 is connected to the first water outlet 120, and the second waterway switch 250 is connected to the second water outlet 130. The first waterway switching device 240 may be tangential to the second pipeline 220/the third pipeline 230, and the second waterway switching device 250 may be tangential to the third pipeline 230/the second pipeline 220, that is, the first waterway switching device 240 is tangential to the second pipeline 220, and the second waterway switching device 250 is tangential to the third pipeline 230, so that the first water outlet 120 is connected to the second pipeline 220, and the second water outlet 130 is connected to the third pipeline 230; or, the first waterway switching device 240 is tangential to the third pipeline 230, and the second waterway switching device 250 is tangential to the second pipeline 220, so that the first water outlet 120 is connected with the third pipeline 230, and the second water outlet 130 is connected with the second pipeline 220.

For example, when the dual-channel desalination assembly 100 performs water purification treatment, the first water channel switching device 240 is tangential to the second pipeline 220, the second water channel switching device 250 is tangential to the third pipeline 230, water flowing from the water inlet 110 is purified by the dual-channel desalination assembly 100, the produced pure water is discharged to the second pipeline 220 through the first water outlet 120 and the first water channel switching device 240, and wastewater is discharged to the third pipeline 230 through the second water outlet 130 and the second water channel switching device 250.

When the dual-channel desalination assembly 100 is subjected to reverse electrode flushing, the electrodes of the dual-channel desalination assembly 100 are switched, the first water path switching device 240 is tangential to the third pipeline 230, the second water path switching device 250 is tangential to the second pipeline 220, water flowing in from the water inlet 110 is subjected to reverse electrode flushing on the dual-channel desalination assembly 100, generated wastewater is discharged to the third pipeline 230 through the first water outlet 120 and the first water path switching device 240, and pure water is discharged to the second pipeline 220 through the second water outlet 130 and the second water path switching device 250.

Illustratively, the first waterway switching device 240 and the second waterway switching device 250 include a tangential valve or a plurality of two-way solenoid valve sets or three-way solenoid valves, etc.

In some embodiments, as shown in fig. 2, the conduit system 200 further includes a filter assembly 260 disposed on the first conduit 210, and/or a filter assembly 260 disposed on the second conduit 220.

When filtering component 260 is disposed on first pipeline 210, the water output from first pipeline 210 is filtered by filtering component 260 and then flows into dual-channel desalination assembly 100 through water inlet 110, and dual-channel desalination assembly 100 performs purification treatment on the inflow water, or performs reverse-polarity washing on dual-channel desalination assembly 100 through the inflow water from water inlet 110. Because the water flowing into the dual-flow desalination assembly 100 is filtered by the filtering assembly 260, the risk of fouling of the dual-flow desalination assembly 100 is reduced as compared to flowing tap water directly into the dual-flow desalination assembly 100.

When the filtering component 260 is disposed on the second pipeline 220, in the process of water purification treatment of the dual-channel desalination component 100, the water output from the first pipeline 210 flows into the dual-channel desalination component 100 through the water inlet 110, the dual-channel desalination component 100 performs purification treatment on the inflow water, and the treated water flows into the second pipeline 220 after being filtered by the filtering component 260.

Illustratively, the filter assembly 260 can include a physical entrapment function filter element and/or a physical adsorption function filter element. The physical interception function filter element comprises at least one of a microfiltration membrane, an ultrafiltration membrane and a PP cotton filter element, and the filtration precision of the physical interception function filter element is between 10 nanometers and 5 micrometers, preferably between 10 nanometers and 1 micrometer. The physical adsorption functional filter element comprises at least one of activated carbon particles and activated carbon rods, and the removal rate of COD (Chemical Oxygen Demand) in water by the physical adsorption functional filter element is more than 20%, and preferably more than 50%.

Specifically, the dual-channel desalination assembly 100 includes an electrodialysis membrane filter element, which can cause directional migration of cations and anions when powered on, so as to realize water purification treatment, and may be referred to as an electrically-driven dual-channel desalination filter element.

Specifically, fig. 3 and 4 show a schematic view of a structure of an electrodialysis membrane cartridge 300.

As shown in fig. 3 and 4, the electrodialysis membrane cartridge 300 includes one or more pairs of electrodes 310, and at least one pair of electrodes 310 has a cation exchange membrane 320 and an anion exchange membrane 330 disposed therebetween, and the cation exchange membrane 320 are disposed in an opposite staggered manner. For example, in the electrodialysis membrane cartridge 300 shown in fig. 3 and 4, a plurality of cation exchange membranes 320 and a plurality of anion exchange membranes 330 are arranged between a pair of electrodes 310 in an alternating manner of cation exchange membranes 320-anion exchange membranes 330-cation exchange membranes 320. The cation exchange membrane 320 and the anion exchange membrane 330 are spaced apart, for example, water passes between the cation exchange membrane 320 and the anion exchange membrane 330 as it passes through the electrodialysis membrane cartridge 300.

As shown in fig. 3 and 4, the pair of electrodes 310 includes a first electrode 311 and a second electrode 312, wherein the first electrode 311 is disposed opposite the cation exchange membrane 320 adjacent to the first electrode 311, and the second electrode 312 is disposed opposite the cation exchange membrane 320 adjacent to the second electrode 312.

Fig. 3 is a schematic diagram showing the operation principle of the electrodialysis membrane filter element 300 in the process of purifying water. The potential of the first electrode 311 is higher than that of the second electrode 312, that is, the first electrode 311 is a positive electrode, and the second electrode 312 is a negative electrode. At this time, anions in the raw water to be purified, such as Cl ", move toward the anode direction and migrate to the flow channel between the cation exchange membrane 320 and the anion exchange membrane 330 through the anion exchange membrane 330, and cations in the raw water, such as Na +, move toward the cathode direction and also migrate to the flow channel between the cation exchange membrane 320 and the anion exchange membrane 330 through the cation exchange membrane 320; so that the concentrations of the cations and the anions in the flow channel between the cation exchange membrane 320 and the anion exchange membrane 330 are higher and higher, and the concentrations of the cations and the anions in the flow channel between the anion exchange membrane 330 and the cation exchange membrane 320 are lower and lower. The water containing cations such as Na + and anions such as Cl-with low concentration can be called pure water, and the pure water flows out from a flow passage between the anion exchange membrane 330 and the cation exchange membrane 320; water containing cations such as Na + and anions such as Cl-with high concentration can be called waste water, and the waste water flows out from a flow passage between the cation exchange membrane 320 and the anion exchange membrane 330.

As shown in fig. 4, during the reverse-polarity washing process of the electrodialysis membrane cartridge 300, the first electrode 311 and the second electrode 312 are switched so that the potential of the first electrode 311 is lower than the potential of the second electrode 312, i.e. the first electrode 311 is a negative electrode, and the second electrode 312 is a positive electrode. At this time, anions such as Cl "in the raw water move toward the anode through the anion exchange membrane 330 and migrate into the flow channel between the anion exchange membrane 330 and the cation exchange membrane 320, and cations such as Na + in the raw water move toward the cathode and also migrate into the flow channel between the anion exchange membrane 330 and the cation exchange membrane 320 through the cation exchange membrane 320. The generated pure water flows out from the flow passage between the cation exchange membrane 320 and the anion exchange membrane 330, and the waste water flows out from the flow passage between the anion exchange membrane 330 and the cation exchange membrane 320.

Illustratively, as shown in fig. 5, the household water purifying apparatus may further include a power supply assembly 10 and a driving assembly 20, wherein the power supply assembly 10 is connected to the dual-channel desalination assembly 100, and applies a voltage to the dual-channel desalination assembly 100. For example, an electrodialysis membrane filter element is connected to supply power to the electrodialysis membrane filter element. Illustratively, the power supply assembly 10 may include a dc power supply. Drive assembly 20 drives water flow to dual-channel desalination assembly 100. Illustratively, the drive assembly 20 may comprise a self-priming pump.

In some embodiments, the voltage at which the power supply assembly 10 supplies power to the electrodialysis membrane filter element can be adjusted, and the salt rejection rate of the electrodialysis membrane filter element changes when the voltage supplied by the power supply assembly 10 is adjusted.

In other embodiments, the dual-flow desalination assembly 100 is removably received within the interior of a domestic water purification apparatus such that the dual-flow desalination assembly 100 can be removed from the domestic water purification apparatus for flushing when desired.

In some embodiments, as shown in fig. 5, the household water purifying apparatus further includes a control assembly 30, the control assembly 30 is connected to the power supply assembly 10, the driving assembly 20, the first waterway switching device 240 and the second waterway switching device 250, and the power supply assembly 10 is connected to the dual-channel desalination assembly 100. Illustratively, the control component 30 may include, for example, a single chip microcomputer or the like.

Illustratively, the control assembly 30 may include input devices, which may include, for example, buttons, knobs, touch screens, microphones, and the like.

Illustratively, when the control unit 30 detects a control operation through the input device, such as a user pressing a self-cleaning button, or sends out a voice including a self-cleaning command, the power supply unit 10 is controlled to switch the electrodes of the dual-channel desalination assembly 100, and the first water path switching device 240 and the second water path switching device 250 are controlled to be tangential to the third pipeline 230 and the second water path switching device 220, so that the water input from the first pipeline 210 flows into the dual-channel desalination assembly 100, the reverse-polarity washing is performed on the dual-channel desalination assembly 100, and the wastewater is output to the third pipeline 230.

In some embodiments, control assembly 30 switches to the flushing mode when the operating state of dual-channel desalination assembly 100 reaches a predetermined condition, for example, when the water purification operation time of dual-channel desalination assembly 100 reaches a predetermined time, such as 30 minutes, control assembly 30 controls power supply assembly 10 to switch electrodes to dual-channel desalination assembly 100, and controls first water path switching device 240 to tangentially connect to third pipeline 230 and second water path switching device 250 to tangentially connect to second pipeline 220, so that the water input from first pipeline 210 flows into dual-channel desalination assembly 100 to perform reverse-polarity flushing to dual-channel desalination assembly 100.

Exemplary, the operating conditions of the dual-channel desalination assembly 100 to the predetermined conditions include, but are not limited to: the double-flow-channel desalination assembly 100 is not operated currently, and the electric quantity Q of the accumulated operation of the double-flow-channel desalination assembly 100 reaches a first preset electric quantity threshold value Q1; alternatively, the dual-flow desalination assembly 100 is currently operating, and the accumulated operating charge Q of the dual-flow desalination assembly 100 reaches a second predetermined charge threshold Q2, wherein the first predetermined charge threshold Q1 is less than the second predetermined charge threshold Q2. That is, the desalination voltage applied to the dual-channel desalination assembly 100, the operation time, etc. are monitored and recorded, and the electric quantity Q during the operation of the dual-channel desalination assembly 100 is accumulated. When the accumulated power Q reaches a first preset threshold Q1, for example, 90% of the set power Q0, and the user stops using water, the back-flushing process is started, the power supply module 10 is controlled to switch the electrodes of the dual-channel desalination module 100, and the first water path switching device 240 is controlled to tangentially connect to the third pipeline 230, the second water path switching device 250 is controlled to tangentially connect to the second pipeline 220, and the water input from the first pipeline 210 flows into the dual-channel desalination module 100, so as to perform back-flushing on the dual-channel desalination module 100. Or, if the household water purifying device is always in the working state and the user does not stop using water, when the accumulated electric quantity Q reaches a second preset threshold Q2, for example, 1.5 times of the set electric quantity Q0, the reverse-polarity flushing process is forcibly started, the power supply assembly 10 is controlled to switch the electrodes of the dual-channel desalination assembly 100, and the first water path switching device 240 is controlled to tangentially connect to the third pipeline 230, the second water path switching device 250 is controlled to tangentially connect to the second pipeline 220, water input from the first pipeline 210 flows into the dual-channel desalination assembly 100, and the reverse-polarity flushing is performed on the dual-channel desalination assembly 100.

By monitoring the working state of the double-flow-channel desalination assembly 100, when the working state of the double-flow-channel desalination assembly 100 reaches a preset condition, the reverse electrode washing is automatically carried out on the double-flow-channel desalination assembly 100, so that the phenomenon that the reverse electrodes of the double-flow-channel desalination assembly 100 are too frequent, and the use experience of a user is influenced is avoided; and avoids the problem that the dual-flow desalting component 100 is not flushed in time to cause scale deposition due to too few inversion frequencies of the dual-flow desalting component 100.

In some embodiments, the outlet direction of the second pipe 220 may be further connected to a heating unit, for example, a heat exchanger. The heating unit may heat the water flowing out of the second pipe 220 to provide the user with hot water of a desired temperature.

Illustratively, the water outlet direction of the second pipe 220 is connected to a plurality of water outlet pipes, and at least one of the water outlet pipes is provided with a heating unit.

In some embodiments, as shown in FIG. 2, a temperature detection assembly 40 may be further disposed on the second conduit 220, and the temperature detection assembly 40 is used for detecting the temperature of the pure water generated after the water purification treatment of the dual-channel desalination assembly 100.

In some embodiments, as shown in fig. 2, the conduit system 200 further includes a conductivity detection assembly 50 disposed on the first conduit 210 and/or a conductivity detection assembly 50 disposed on the second conduit 220. The water quality of the water at the corresponding position can be detected by the conductivity detection assembly 50. For example, the TDS value is a water quality test indicator specifically set for purified water, and represents the total soluble solids content of water. The TDS value can reflect the water quality to a certain degree, and generally, the lower the TDS value is, the less soluble salts such as heavy metal ions in the water are, and the purer the water quality is.

For example, the conductivity detection assembly 50 is disposed on the second pipeline 220, and the conductivity of the water discharged from the dual-channel desalination assembly 100 is detected by the conductivity detection assembly 50, so as to determine whether the water purification effect of the dual-channel desalination assembly 100 can meet the requirement.

In some embodiments, as shown in fig. 5, the control module 30 is connected to the conductivity detection module 50, the power supply module 10, the first water path switching device 240 and the second water path switching device 250, and the power supply module 10 is connected to the dual-channel desalination module 100. The control unit 30 may include, for example, a single chip microcomputer or the like.

Illustratively, the conductivity detection assembly 50 is coupled to the control assembly 30. Control assembly 30 can control power supply assembly 10 to adjust the power supply voltage to dual-channel desalination assembly 100 based on conductivity data detected by conductivity detection assembly 50 in second conduit 220. For example, the greater the conductivity data detected by the conductivity detection assembly 50 on the second conduit 220, the greater the supply voltage provided by the power supply assembly 10 to the dual-channel desalination assembly 100 to enhance the effectiveness of the purification process.

In some embodiments, as shown in fig. 2, a flow sensing assembly 60 may also be provided on the first conduit 210 and/or the second conduit 220. Illustratively, the flow sensing assembly 60 is coupled to the control assembly 30.

In some embodiments, the household water purifying apparatus further comprises a water tank capable of storing water, one end of the first pipe 210 is connected to an outlet of the water tank, the other end is connected to the water inlet 110, and an inlet of the water tank is connected to the third pipe 230. The wastewater treated by the dual-channel desalination assembly 100 flows into the water tank through the third pipeline 230 for reuse, thereby avoiding the waste of water and improving the utilization rate of water.

Illustratively, the water tank comprises a transparent shell or a transparent window is arranged on the shell, so that a user can conveniently check the water quality, the water level and the like in the water tank.

Illustratively, the water tank may further include a water filling port through which water to be purified may be added to the water tank. For example, the water filling port is connected with a tap water pipe. In an exemplary embodiment, a liquid level meter is further disposed in the water tank, and when the liquid level in the water tank drops to a set value, the valve of the tap water pipe can be controlled to open to add water to the water filling port of the water tank.

For example, water stored in the tank may flow into the dual-channel desalination assembly 100 via the first conduit 210, and the inflow water may be purified by the dual-channel desalination assembly 100, and the purified water may be output via the second conduit 220.

It is understood that one end of the first pipeline 210 may be directly connected to the tap water pipe, and the other end is connected to the water inlet 110.

The domestic purifier that this description above-mentioned embodiment provided, including double-flow-channel desalination subassembly and pipe-line system, double-flow-channel desalination subassembly includes the water inlet, first delivery port and second delivery port, pipe-line system includes first pipeline, second pipeline and third pipeline, first tube coupling water inlet, first pipeline is used for sending water to the water inlet, when the operating condition of double-flow-channel desalination subassembly reaches the preset condition, to double-flow-channel desalination subassembly conversion electrode, the water that flows in from the water inlet carries out the reversal pole to double-flow-channel desalination subassembly and washes, the waste water of production is discharged through first delivery port or second delivery port, the second pipeline is used for exporting the pure water after double-flow-channel desalination subassembly is handled, the third pipeline is used for exporting the waste water after double-flow-channel desalination subassembly is handled. By automatically carrying out reverse electrode flushing on the double-flow-channel desalting assembly when the preset condition is reached, the phenomenon that the reverse electrodes of the double-flow-channel desalting assembly are too frequently reversed is avoided, so that the use experience of a user is influenced; and avoids the problem that the double-flow desalting component cannot be flushed in time to cause scale deposition due to too few inversion frequencies of the double-flow desalting component, and also reduces the scaling risk of the double-flow desalting component, thereby ensuring the quality of the prepared pure water.
