It is to be understood that the single channel desalination assembly 100 uses only one water inlet and one water outlet for the purification of water flowing therethrough, and thus may be referred to as a single channel desalination assembly.

In some embodiments, the single channel desalination assembly 100 can, of course, also include other water inlets and/or outlets. For example, when the single-channel desalination assembly 100 is flushed and regenerated, the generated wastewater can be discharged through the water outlet. When the single-channel desalination assembly 100 is purifying water flowing through, the water inlets and/or outlets other than the first water inlet 110 and the first water outlet 120 can be closed, thereby forming a single-channel structure.

The single channel desalination module 100 may not discharge wastewater when purifying water flowing therethrough. Through adopting the desalination subassembly of single current way to carry out the water purification, the water that gets into single current way desalination subassembly 100 can be followed the delivery port and discharged, obtains purification treatment simultaneously, does not produce waste water in this process, has improved the utilization ratio of water.

Specifically, the single-channel desalination assembly comprises an electrically driven desalination filter element, a capacitance desalination filter element, a membrane capacitance desalination filter element, a bipolar membrane electrodeionization filter element and the like, and can cause the directional migration of cations and anions when being electrified, so that the water purification treatment is realized, and the filter element can be called as an electrically driven desalination filter element.

Specifically, as shown in fig. 2 and 3, a schematic diagram of a structure of a bipolar membrane electrodeionization filter cartridge 900 is shown.

As shown in fig. 2 and 3, the bipolar membrane electrodeionization filter cartridge 900 includes one or more pairs of electrodes 910, and at least one bipolar membrane 920 or a plurality of spaced-apart bipolar membranes 920 is disposed between at least one pair of electrodes 910. Wherein, bipolar membrane 920 includes cation exchange membrane 921 and anion exchange membrane 922, and cation exchange membrane 921 and anion exchange membrane 922 set up relatively, compound together. For example, the bipolar membrane 920 can be produced by a hot press molding method, a bonding molding method, a casting molding method, an anion and cation exchange radical method, an electrodeposition molding method, or the like. Specifically, there is no space between the cation exchange membrane 921 and the anion exchange membrane 922 on one bipolar membrane 920, for example, water does not pass between the cation exchange membrane 921 and the anion exchange membrane 922 on the same bipolar membrane 920 when flowing through the bipolar membrane electrodeionization filter cartridge 900.

Here, the potential of the first electrode 911 is higher than that of the second electrode 912, that is, a voltage in a forward direction is applied between the first electrode 911 and the second electrode 912. At this time, anions such as chloride ions in the raw water to be purified move towards the first electrode 911, and replace OH < - > in the anion exchange membrane 922 in the direction of the first electrode 911, and the OH < - > enters the flow channel between the adjacent bipolar membranes 920; meanwhile, cations such as Na + in the raw water move towards the second electrode 912 to replace H + in the cation exchange membrane 921 in the direction of the second electrode 912, and the H + enters the flow channel; h + and OH-are subjected to neutralization reaction in the flow channel to generate water, so that the salt in the raw water is removed, and purified pure water flows out from the tail end of the flow channel.

Therefore, when the power is off or reverse voltage is applied to the desalting filter cores such as the bipolar membrane electrodeionization filter core 900 and the like, cations such as Na < + > and the like and anions such as chloride ions and the like adsorbed on the bipolar membrane 920 can be released, so that salt substances in the bipolar membrane electrodeionization filter core can be washed out by water, and regeneration is realized; water carrying cations such as Na + and anions such as chloride ions can be called concentrated water.

Illustratively, the activated carbon filter element comprises a scale inhibition activated carbon filter element and a non-scale inhibition activated carbon filter element, the scale inhibition activated carbon filter element comprises a scale inhibitor and activated carbon, the non-scale inhibition activated carbon filter element only comprises activated carbon, the scale inhibitor on the scale inhibition activated carbon filter element can prevent water from scaling, so that the subsequent double-channel desalination assembly 100 can purify water, and the service life of the double-channel desalination assembly 100 can also be prolonged.

In some embodiments, the pipe system 300 includes a post-filter assembly disposed at the outlet of the second pipe 320, the post-filter assembly including a microfiltration cartridge and/or an activated carbon cartridge. The quality of the purified water from the single channel desalination module 100 can be further improved by further purifying the purified water with a post-filtration module.

In some embodiments, as shown in fig. 5 and 6, the household water purifying apparatus further includes a control module 400, a conductivity collection module 10, and a power supply module 500, wherein the control module 400 is connected to the conductivity collection module 10, the conductivity collection module 10 is disposed in the second pipeline 320 for collecting conductivity of purified water, and the power supply module 500 supplies power to the electrically driven single channel desalination module 100.

The water quality of water at the corresponding position can be detected through the conductivity acquisition assembly. 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 some embodiments, the voltage supplied by the power supply module 500 to the electrically driven single channel desalination module 100 can be adjusted in magnitude and direction, and the desalination rate of the electrically driven single channel desalination module 100 can be changed by adjusting the voltage supplied by the power supply module 500, so that the conductivity of the water can be changed.

Illustratively, the control assembly 400 is further configured to obtain the conductivity collected by the conductivity collection assembly 10, and adjust the voltage of the electrically driven single channel desalination assembly 100 to adjust the conductivity of the water when the conductivity does not reach the target conductivity and when the cumulative water purification time period of the ion exchange resin cartridge 200 reaches a preset time period. The accumulated water purification time of the ion exchange resin filter element 200 is the accumulated time for purifying water by the ion exchange resin filter element 200, and after regeneration or cleaning, the accumulated water purification time is cleared, and the preset time can be set based on actual conditions, for example, the preset time is 15 days.

Illustratively, the target conductivity may be stored in the memory of the control component 400 in advance, or the control component 400 may determine the target conductivity according to a setting operation of a user. When the conductivity of the water reaches the target conductivity, the water can be determined to be sufficiently pure, for example, to meet drinking standards.

Illustratively, in the process of purifying water, the salinity concentration in the water can be detected in real time by detecting the electrical conductivity of the water, and the desalination rate of the electrically-driven single-channel desalination module 100 can be adjusted by changing the voltage of the electrically-driven single-channel desalination module 100, so as to ensure the stability of the quality of the produced water.

In some embodiments, the control assembly 400 includes an input device, which may include, for example, a button, a knob, a touch screen, a microphone, and the like.

For example, a user may perform a setting operation of the target conductivity through the input device, and the control component 400 may determine the target conductivity according to the setting operation of the user.

For example, when the input device detects a water outlet control operation, such as a user pressing a water outlet button, or uttering a voice including a water outlet command, it is determined whether the conductivity detected by the first conductivity acquisition assembly 10 reaches the target conductivity. When the conductivity reaches the target conductivity, the control assembly 400 may control the outlet valve of the second conduit 320 to send the water out for use by the user.

In some embodiments, the single-channel desalination assembly 100 can include a housing and a filter element removably received within an interior of the housing. The filter element includes, for example, a physisorption desalination filter element and/or a chemisorption desalination filter element as previously described. The filter elements of the single-channel desalination assembly 100 can be removed and flushed as needed to regenerate the filter elements of the single-channel desalination assembly 100.

In some embodiments, the second pipeline 320 includes a third water inlet, a third water outlet, a fourth water outlet, a heating pipeline, and a normal temperature pipeline, the purified water flowing out of the second water outlet 230 flows into the second pipeline 320 through the third water inlet, the third water outlet is connected to the heating pipeline, and the fourth water outlet is connected to the normal temperature pipeline.

Exemplarily, the heating pipeline comprises a flow regulating assembly, a fourth water inlet, a heating assembly and a fifth water outlet, wherein water flowing out of the third water outlet flows in from the fourth water inlet after being regulated by the flow regulating assembly, the heating assembly heats the flowing water, and the heated water flows out from the fifth water outlet.

Illustratively, the heating assembly includes, for example, a heat exchanger or the like, and the heating assembly can heat the inflow water to provide hot water at a desired temperature to a user.

For example, the flow regulating assembly includes a flow regulating valve and the like, and the flow regulating assembly can perform flow regulation on the water flowing out from the third water outlet, so that rapid heating of the water can be realized, for example, in the case that the heating power of the heating assembly is fixed, the heating is faster when less water flows in through the flow regulating assembly, and conversely, the heating is slower when more water flows in through the flow regulating assembly.
