In an embodiment, the domestic water purification device comprises at least one electrically driven desalination assembly comprising at least one of an electrically driven single-channel desalination assembly and an electrically driven double-channel desalination assembly, the electrically driven single-channel desalination assembly comprising at least one of a capacitive desalination cartridge, a membrane capacitive desalination cartridge, a bipolar membrane (BP) electrodeionization cartridge, the electrically driven double-channel desalination assembly comprising at least one of an electrodialysis unit, a reverse electrodialysis unit.

It is understood that the electrically driven single-channel desalination module only uses one water inlet and one water outlet when purifying the water flowing through, and needs to be powered by the power supply module, and thus can be referred to as an electrically driven single-channel desalination module.

Specifically, as shown in fig. 2 and 3, the bipolar membrane electrodeionization filter cartridge 900 comprises one or more pairs of electrodes 910, and at least one pair of electrodes 910 has one bipolar membrane 920 or a plurality of spaced bipolar membranes 920 disposed therebetween. 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.

As shown in fig. 2 and 3, the pair of electrodes 910 includes a first electrode 911 and a second electrode 912, wherein the first electrode 911 is disposed opposite to a cation exchange membrane 921 of the bipolar membrane 920 adjacent to the first electrode 911, and the second electrode 912 is disposed opposite to an anion exchange membrane 922 of the bipolar membrane 920 adjacent to the second electrode 912.

Fig. 2 is a schematic diagram showing the operation principle of the bipolar membrane electrodeionization filter element 900 in the process of purifying water. 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.

As shown in fig. 3, when a voltage in the opposite direction is applied between the first electrode 911 and the second electrode 912, so that the potential of the first electrode 911 is lower than that of the second electrode 912, OH "and H + ions are generated on the surfaces of the cation exchange membrane 921 and the anion exchange membrane 922 of the bipolar membrane 920 under the action of an electric field, cations such as Na + inside the cation exchange membrane 921 are replaced by H + ions and move toward the first electrode 911 at a low potential, anions such as chloride ions in the anion exchange membrane 922 are replaced by OH" and move toward the second electrode 912 at a high potential, and the cations such as Na + and the anions such as chloride ions enter the flow channel and can be washed out by water flowing through the bipolar membrane electrodeionization filter 900. 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 of 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.

In one embodiment, according to the current working voltage, the current flow rate and the preset maximum water temperature, determining the lowest conductivity of the purified water of the household water purification device under the current working voltage and the current flow rate, that is, querying a mapping relation table between the conductivity under the current working voltage and the current flow rate and the water temperature, obtaining the conductivity corresponding to the preset maximum water temperature, and taking the conductivity corresponding to the preset maximum water temperature as the lowest conductivity; determining whether the minimum conductivity is less than or equal to the target conductivity, and if the minimum conductivity is less than or equal to the target conductivity, determining a target temperature of the water entering the electrically driven desalination assembly based on the current operating voltage, the current flow rate, and the target conductivity. The preset maximum water temperature is set according to an actual situation, which is not specifically limited in the present application, for example, the preset maximum water temperature is 50 ℃.

And S103, adjusting the temperature of the water entering the electrically-driven desalting component according to the target temperature so as to enable the conductivity of the purified water of the household water purifying device to reach the target conductivity.

Wherein the conductivity of the purified water of the domestic water purification apparatus changes with the temperature of the water entering the electrically driven desalination module and the flow rate of the water entering the electrically driven desalination module and/or the operating voltage of the electrically driven desalination module, and thus the conductivity of the purified water of the domestic water purification apparatus can be adjusted by adjusting the temperature of the water entering the electrically driven desalination module and the flow rate of the water entering the electrically driven desalination module and/or the operating voltage of the electrically driven desalination module, it can be understood that, with a constant operating voltage of the electrically driven desalination module, the faster the flow rate of the water entering the electrically driven desalination module, the higher the conductivity of the purified water of the domestic water purification apparatus and the worse the slower the flow rate of the water entering the electrically driven desalination module, the lower the conductivity of the purified water of the domestic water purification apparatus and the better the water quality.
