The embodiment of the application provides a household water purifying device which can be a water purifier, such as a table-board type water purifying/drinking machine.

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, a third pipe 230, and a water quality detection device 240 disposed on the first pipe 210, the first pipe 210 is connected to the water inlet 110, and the first pipe 210 is used for conveying raw water to the water inlet 110. The water quality detection device 240 is used to detect the water quality of raw water to be subjected to purification treatment. 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.

In this embodiment, the dual-channel desalination assembly 100 performs purification treatment on water, and the purification treatment includes a plurality of different water quality adjustment gears, wherein the different water quality adjustment gears correspond to different purities of pure water. Illustratively, the water quality adjusting gear comprises a pure water quality adjusting gear, an electrolyte quality adjusting gear and the like, wherein the purity of the pure water taken out by the pure water quality adjusting gear is higher than that of the pure water taken out by the electrolyte quality adjusting gear. A user can set a water quality adjusting gear of the double-flow-channel desalination assembly 100 according to the own needs, for example, if the user wants to obtain pure water with high purity, the water quality adjusting gear of the double-flow-channel desalination assembly 100 can be set as a pure water quality adjusting gear; if the user does not need to obtain pure water of that high concentration, the water quality adjustment stage of the dual-channel desalination assembly 100 can be set to the electrolyte water quality adjustment stage.

In the process of water purification treatment by the dual-channel desalination assembly 100, according to the water quality of the raw water detected by the water quality detection device 240 and the current water quality adjustment gear of the dual-channel desalination assembly 100, a suitable voltage is applied to the dual-channel desalination assembly 100, and the dual-channel desalination assembly 100 performs corresponding purification treatment on the raw water flowing into the dual-channel desalination assembly 100 from the water inlet 110, so as to generate pure water and wastewater with corresponding purity. The second line 220 is used to output pure water of corresponding purity after being processed by the dual-channel desalination assembly 100, and the third line 230 is used to output wastewater after being processed by the dual-channel desalination assembly 100.

For example, if the quality of the raw water is pure and the current water quality adjustment stage of the dual-channel desalination assembly 100 is the electrolyte water quality adjustment stage, a lower voltage, such as 12V, is applied to the dual-channel desalination assembly 100, and the dual-channel desalination assembly 100 performs purification treatment on the raw water at the lower voltage to generate pure water with purity meeting the requirement of the user.

For another example, if the raw water is not pure and the current water quality adjustment position of the dual-channel desalination assembly 100 is the pure water quality adjustment position, a higher voltage, for example, a high voltage of 36V, is applied to the dual-channel desalination assembly 100, and the dual-channel desalination assembly 100 performs purification treatment on the raw water under the high voltage, so as to generate pure water with purity meeting the user requirement.

It should be noted that the higher the voltage applied to the dual-channel desalination assembly 100, the higher the purity of the pure water produced by the dual-channel desalination assembly 100. Conversely, the lower the voltage applied to the dual-channel desalination assembly 100, the lower the purity of the pure water produced by the dual-channel desalination assembly 100.

Through the quality of water according to the raw water to and the current quality of water of double-flow-channel desalination subassembly 100 adjusts the gear, apply suitable voltage to double-flow-channel desalination subassembly 100, prepare the pure water that accords with user's demand purity, also realize quality of water and adjust, the quality of water of the pure water of preparing to take out is no longer single invariable, but can accord with user's demand, thereby has improved user's use greatly and has experienced. Not only avoids the problem that the quality of the prepared pure water is not up to standard due to low voltage, namely the requirement of a user cannot be met, but also avoids the risk that the double-flow-channel desalination assembly 100 is scaled due to high voltage although the quality of the prepared pure water is up to standard.

In some embodiments, as shown in fig. 2, the pipe system 200 further includes a waterway switch device 250, wherein the waterway switch device 250 is connected to the first water outlet 120 and the second water outlet 130. The waterway switching device 250 may switch the communication manner of the first water outlet 120, the second water outlet 130 and the second pipeline 220 and the third pipeline 230, for example, the waterway switching device 250 may tangentially communicate the first water outlet 120 with the second pipeline 220 and communicate the second water outlet 130 with the third pipeline 230, or the waterway switching device 250 may tangentially communicate the first water outlet 120 with the third pipeline 230 and communicate the second water outlet 130 with the second pipeline 220. When the waterway switching device 250 tangentially communicates the first water outlet 120 with the second pipeline 220 and communicates the second water outlet 130 with the third pipeline 230, the water flowing in from the water inlet 110 is purified by the dual-channel desalination assembly 100, the generated pure water is discharged to the second pipeline 220 through the first water outlet 120, and the wastewater is discharged to the third pipeline 230 through the second water outlet 130. When the waterway switching device 250 tangentially communicates the first water outlet 120 with the third pipeline 230 and communicates the second water outlet 130 with the second pipeline 220, the water flowing in from the water inlet 110 is purified by the dual-channel desalination assembly 100, the generated pure water is discharged to the second pipeline 220 through the second water outlet 130, and the wastewater is discharged to the third pipeline 230 through the first water outlet 120.

Illustratively, waterway switching device 250 includes a tangential valve, such as a four-way valve, or waterway switching device 250 includes a plurality of three-way solenoid valve sets, and the like.

In some embodiments, as shown in fig. 3, the waterway switching device 250 includes a first three-way solenoid valve 251 and a second three-way solenoid valve 252, wherein the first three-way solenoid valve 251 is connected to the first water outlet 120, and the second three-way solenoid valve 252 is connected to the second water outlet 130. The first three-way solenoid valve 251 may be tangential to the second/

third line

220, 230 and the second three-way solenoid valve 252 may be tangential to the third/

second line

230, 220, i.e. the first three-way solenoid valve 251 is tangential to the second line 220 and the second three-way solenoid valve 252 is tangential to the third line 230, or the first three-way solenoid valve 251 is tangential to the third line 230 and the second three-way solenoid valve 252 is tangential to the second line 220.

When the first three-way solenoid valve 251 is tangential to the second pipeline 220 and the second three-way solenoid valve 252 is tangential to the third pipeline 230, the first water outlet 120 is communicated with the second pipeline 220 and the second water outlet 130 is communicated with the third pipeline 230. The water flowing in 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 waste water is discharged to the third pipeline 230 through the second water outlet 130.

When the first three-way solenoid valve 251 is tangential to the third pipeline 230 and the second three-way solenoid valve 252 is tangential to the second pipeline 220, the first water outlet 120 is communicated with the third pipeline 230 and the second water outlet 130 is communicated with the second pipeline 220. The water flowing in 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 second water outlet 130, and the wastewater is discharged to the third pipeline 230 through the first water outlet 120.

In some embodiments, as shown in fig. 2 and 3, 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 the filtering assembly 260 is disposed on the first pipeline 210, the raw water output from the first pipeline 210 is filtered by the filtering assembly 260 and then flows into the dual-channel desalination assembly 100 through the water inlet 110, and the dual-channel desalination assembly 100 purifies the inflow water, or performs reverse-polarity washing on the dual-channel desalination assembly 100 through the inflow water from the 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 performed by the dual-channel desalination component 100, the raw 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 pure 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. 4 and 5 show a schematic diagram of a structure of an electrodialysis membrane cartridge 300.

As shown in fig. 4 and 5, 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. 4 and 5, a plurality of cation exchange membranes 320 and a plurality of anion exchange membranes 330 are provided between a pair of electrodes 310 in an interleaved 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. 4 and 5, 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. 4 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. 5, 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. 6, 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, as shown in fig. 1-3, the drive assembly 20 may comprise a self-primer pump.

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. 6, 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 water quality detecting device 240 and the water path 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 module 30 detects a control operation through the input device, such as a user pressing a self-cleaning button, or sends a voice including a self-cleaning command, the control power supply module 10 switches the electrodes of the dual-channel desalination assembly 100, and simultaneously controls the waterway switching device 250 to switch the communication between the first water outlet 120 and the second water outlet 130, for example, if the first water outlet 120 is communicated with the second pipeline 220 and the second water outlet 130 is communicated with the third pipeline 230, the control module 30 controls the waterway switching device 250 to tangentially communicate the first water outlet 120 with the third pipeline 230 and communicate the second water outlet 130 with the second pipeline 220, so that the water input from the first pipeline 210 flows into the dual-channel desalination assembly 100, performs reverse-polarity washing on the dual-channel desalination assembly 100, and outputs the wastewater to the third pipeline 230.

In some embodiments, the control module 30 controls the power supply module 10 to apply appropriate corresponding voltages to the dual-channel desalination module according to the quality of the raw water detected by the water quality detection device 240 and the current water quality adjustment gear of the dual-channel desalination module.

Illustratively, the water quality detection device 240 includes a conductivity detection component by which the detected water quality of the raw water includes conductivity data of the raw water. For convenience of description, the conductivity detection module for detecting conductivity data of raw water is hereinafter referred to as a first conductivity detection module, and conductivity data of raw water is referred to as first conductivity data.

Illustratively, the preset conductivity data corresponds to a preset threshold a, for example, the preset threshold a is set to a value range of [200, 600] ppm, and optionally the preset threshold a is set to a value range of [300, 400] ppm. It is understood that the preset threshold a can be flexibly set according to practical situations, and the specific value is not limited herein.

When the first conductivity detection module detects that the first conductivity data of the raw water is smaller than the preset threshold a and the current water quality adjustment gear of the dual-channel desalination module 100 is a first gear, where the first gear requires that the purity of the correspondingly prepared pure water is high, for example, the first gear is a pure water quality adjustment gear. The control assembly 30 controls the power supply assembly 10 to apply a first voltage to the dual-channel desalination assembly 100, for example, the control assembly 30 controls the power supply assembly 10 to apply a maximum voltage of 36V to the dual-channel desalination assembly 100.

When the first conductivity detection module detects that the first conductivity data of the raw water is smaller than the preset threshold a and the current water quality adjustment gear of the dual-channel desalination module 100 is the second gear, where the purity of the corresponding prepared pure water required by the second gear is smaller than the purity of the corresponding prepared pure water required by the first gear, for example, the second gear is an electrolyte water quality adjustment gear. The control assembly 30 controls the power supply assembly 10 to apply a second voltage to the dual-channel desalination assembly, wherein the first voltage is greater than the second voltage. For example, the control assembly 30 controls the power supply assembly 10 to apply a 24V voltage to the dual-channel desalination assembly 100.

When the first conductivity detection module detects that the first conductivity data of the raw water is smaller than the preset threshold a and the current water quality adjustment gear of the dual-channel desalination assembly 100 is the second gear, the control module 30 controls the power supply module 10 to apply a suitable second voltage to the dual-channel desalination assembly 100 according to the second conductivity data of the pure water output by the second pipeline 220 detected by the second conductivity detection module, that is, the control module 30 controls and adjusts the voltage applied to the dual-channel desalination assembly 100 by the power supply module 10 in a feedback manner according to the water quality of the prepared pure water, so that the water quality of the pure water prepared by the dual-channel desalination assembly 100 meets the requirement of a user.

Illustratively, the value range of the first current interval I1 is set to [0.5, 1] a, and optionally the value range of the first current interval I1 is set to [0.5, 0.8] a. When the first conductivity data of the raw water is greater than or equal to the preset threshold a, that is, the concentration of the electrolyte in the raw water is high, the control component 30 controls the voltage and the current of the dual-channel desalination component 100, so as to control the water purification effect of the dual-channel desalination component 100, so as to meet the user requirement.

Wherein the current in the first current interval I1 is larger than the current in the second current interval I2. Illustratively, the value range of the second current interval I2 is set to [0.1, 0.5] a, and optionally the value range of the second current interval I2 is set to [0.2, 0.4] a.

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.
