Fig. 1 is a schematic structural diagram of the water boiling device in this embodiment, and fig. 2 is a schematic block diagram of the water boiling device in this embodiment.

For example, the water boiling device may include an electric kettle and a water dispenser, and the electric kettle is taken as an example below.

Referring to fig. 1, the water boiling device includes a water container 100, a heating assembly 300, a filter cartridge module 200, a circulation pump 400, and a control assembly 500.

Wherein, the water container 100 includes a water outlet 110 and a water inlet 120, and can store water.

In some embodiments, the water container 100 further includes an upper cover 130, after the upper cover 130 is opened, a user can fill water into the water container 100, and the water outlet 110 of the water container 100 is used for communicating with the input end of the circulation pump 400; the water inlet 120 of the water container 100 is used for communicating with the output end of the filter element module 200, so that the circulating pump 400 can drive the water in the water container 100 to flow back into the water container 100 after the water flows to the water inlet 120 through the filter element module 200.

In some embodiments, the water container 100 is further provided with a switch assembly at the outside thereof, the switch assembly comprises a water boiling switch and/or a water purifying switch, and the water boiling switch is used for enabling a user to press the water boiling switch to realize a water boiling starting operation of the water boiling device after the water boiling device is plugged; after the water boiling device is powered on, a user presses the water purifying switch to realize the water purifying operation of the water boiling device, or when the user presses the water boiling switch and the water purifying switch, the water boiling device executes the water purifying and boiling operation.

It can be understood that the switch component can be a key to control the switch for boiling water and purifying water simultaneously, or can be two separate keys, or a display screen with a touch function, or a voice input component, and can recognize the voice water boiling operation instruction input by the user.

The water boiling device further includes a heating assembly 300 for heating the water in the water container 100.

In some embodiments, the heating assembly 300 may be disposed at a bottom or a peripheral side of the water container 100, and the heating assembly 300 may include a resistance wire of a heating tube, and after water boiling is started, the resistance wire of the heating tube is used to generate heat, and then the heat is transferred into the water container 100 through an aluminum plate to be heated, and water vapor generated when water is boiling deforms a bimetal of the steam temperature sensing element, and pushes the power switch through a lever principle by using the deformation, so that the water boiling device is automatically powered off after water is boiled. The power failure is not self-resetting, so the kettle can not be automatically heated after the power failure.

The water boiler further comprises a cartridge module 200 comprising a single channel desalination assembly 201, an input end of the cartridge module 200 is communicated with the inside of the water container 100 through the water outlet 110, and an output end of the cartridge module 200 is communicated with the inside of the water container 100 through the water inlet 120.

In some embodiments, the cartridge module 200 may include a single-channel desalination assembly 201, and the water in the water container 100 is driven by a circulation pump 400 to flow through the cartridge module 200 for purification.

In some embodiments, the single-channel desalination assembly 201 uses only one water inlet 120 and one water outlet 110 for purifying the water flowing through, and thus can be referred to as a single-channel desalination assembly.

In some embodiments, the single channel desalination assembly 201 can of course also include other inputs and/or outputs. For example, when the single channel desalination module 201 is flushed and regenerated, the resulting wastewater can be discharged through the output port. When the single-channel desalination module 201 is performing purification treatment on the flowing water, the input and/or output terminals other than the input and output terminals for purification treatment can be closed, so as to form a single-channel structure.

The single channel desalination module 201 may not discharge wastewater when performing purification treatment on the passing water. 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 201 can be followed the output and discharged, obtains purification treatment simultaneously, does not produce waste water at this in-process, has improved the utilization ratio of water.

In some embodiments, the single-channel desalination assembly 201 comprises a physisorption desalination cartridge and/or a chemisorption desalination cartridge.

Illustratively, the chemisorptive desalination cartridge can include at least one of an ion exchange (IX) resin cartridge, a bipolar membrane (Biopolar, BP) desalination cartridge.

Exemplary, the physisorption desalination filter element may include at least one of a Capacitive Desalination (CDI) filter element, a Membrane Capacitive Desalination (MCDI) filter element.

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

Specifically, as shown in fig. 3 and 4, a schematic diagram of a structure of a bipolar membrane electrodeionization filter cartridge 900 is shown.

As shown in fig. 3 and 4, 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.

As shown in fig. 3 and 4, 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. 3 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. 4, 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 < + >, anions such as chloride ions and the like adsorbed on the bipolar membrane 920 are released, so that salt substances in the desalting filter core can be washed out by water to realize regeneration; water carrying cations such as Na + and anions such as chloride ions can be called concentrated water.

The water boiling device further includes a circulation pump 400 capable of driving the water in the water container 100 to flow to the water inlet 120 through the filter cartridge module 200.

In some embodiments, as shown in fig. 1, an input end of the circulation pump 400 is connected to the water outlet 110 of the water container 100, such that water in the water container 100 can flow into the circulation pump 400 through the water outlet 110 and the input end of the circulation pump 400, an output end of the circulation pump 400 is communicated with an input end of the filter cartridge module 200, and an output end of the filter cartridge module 200 is communicated with the water inlet 120. When the circulation pump 400 is activated, the circulation pump 400 drives the water in the water container 100 to flow into the filter cartridge module 200 through the water inlet 120, the filter cartridge module 200 performs a filtering process, and the processed water flows back to the inside of the water container 100 through the water inlet 120. Since the circulation pump 400 circulates water in the filter cartridge module 200 after being activated, water in the water container 100 can be circulated and filtered.

In some embodiments, the positions of the circulation pump 400 and the cartridge module 200 can be reversed, i.e., the water outlet 110 of the water container 100 is in communication with the input of the cartridge module 200, the output of the cartridge module 200 is in communication with the input of the circulation pump 400, and the output of the circulation pump 400 is in communication with the water inlet 120 of the water container 100. When the circulation pump 400 is started, the circulation pump 400 can drive the water in the water container 100 to circulate and filter the water in the filter element module 200.

Illustratively, the filter cartridge module 200 can further include a filter assembly 202, the filter assembly 202 being in series or in parallel with the single channel desalination assembly 201.

In some embodiments, filter assembly 202 includes a PP cotton filter element and/or an activated carbon filter element. The PP cotton filter element refers to a polypropylene melt-blown filter element, can be used in large scale in water purification, has excellent chemical compatibility, is suitable for filtering strong acid, strong alkali and organic solvent, and has the advantages of strong pollutant carrying capacity, long service life and low cost; the active carbon filter element integrates the functions of adsorption, filtration, interception and catalysis, can effectively remove organic matters, residual chlorine and other radioactive substances in water, and has the effects of decoloring and removing peculiar smell. The PP cotton filter element and/or the activated carbon filter element are used as the filter assembly, so that harmful substances such as organic matters, residual chlorine and the like in water can be effectively removed, and the water quality can be effectively purified.

In some embodiments, the filter assembly 202 and the single channel desalination assembly 201 can be in a series relationship, as shown in FIG. 1, with the input of the filter assembly 202 in communication with the output of the circulation pump 400, the output of the filter assembly 202 in communication with the input of the single channel desalination assembly 201, and the output of the single channel desalination assembly 201 in communication with the water inlet 120. When the circulation pump 400 is started, the water in the water container 100 is driven to pass through the filtering component 202 and the single-channel desalination component 201, so that the water in the water container 100 can be subjected to filtering treatment by the filtering component 202 and then subjected to desalination treatment by the single-channel desalination component 201, and the water quality is effectively improved.

It is to be understood that the order of placement of the filter assembly 202 and the single channel desalination assembly 201 is not limited and that the filter assembly 202 and the single channel desalination assembly 201 can also be in a parallel relationship.

Illustratively, the water boiling device further comprises a power supply assembly 701, and the power supply assembly 701 is connected with the electrically-driven desalination filter element to supply power to the electrically-driven desalination filter element.

In some embodiments, the voltage at which the power supply assembly 701 supplies power to the electrically driven desalination filter element can be adjusted, and the desalination rate of the electrically driven desalination filter element changes as the voltage supplied by the power supply assembly is adjusted.

The water boiling device further comprises a control assembly 500 connected with the heating assembly 300, the single channel desalination assembly 201, the circulation pump 400 and the TDS sensor 700 for controlling the heating assembly 300, the single channel desalination assembly 201 and the circulation pump 400, wherein the TDS sensor 700 sends a TDS value to the control assembly 500 after detecting the TDS value of the water in the water container 100, and controls the circulation pump 400 and the filter element module 200 to work when the TDS value of the water in the water container 100 is lower than a target value; and controlling the heating assembly 300 to heat the water in the water container 100 when the TDS value of the water is not higher than the target value.

It is understood that TDS (total dissolved solids), measured in milligrams per liter (mg/L), represents how many milligrams of a solid solute comprising the total of inorganic salts and organic matter are dissolved in 1 liter of water, and that by measuring the total dissolved solids, the total salinity of the water can be analyzed. 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, a control assembly 500 is disposed in the water boiling device, and global control is performed through the control assembly 500, taking the filter assembly 202 and the single-channel desalination assembly 201 as an example of a serial connection relationship, when the water boiling device receives a water boiling instruction, first, the control assembly 500 controls the circulation pump 400 to start, and controls the single-channel desalination assembly 201 in the filter element module 200 to start, after the water in the water container 100 sequentially flows through the filter assembly 202 and the single-channel desalination assembly 201 via the water outlet 110 and the circulation pump 400, the water flows back into the water container 100 from the water inlet 120, and the control assembly 500 receives a TDS value of the water in the water container 100 detected by the TDS sensor 700; then, when the control assembly 500 detects that the TDS value is higher than the target value, the circulation pump 400 and the filter cartridge module 200 are controlled to operate.

Taking the filtering component 202 and the single-channel desalination component 201 as an example of a parallel connection relationship, when the water boiling device receives a water boiling instruction, firstly, the control component 500 controls the circulating pump 400 to start, one part of water passing through the circulating pump 400 is filtered by the filtering component 202, the other part of water is desalted by the single-channel desalination component 201, and the treated water returns to the water container from the water inlet 120; also, the control assembly 500 receives the TDS value of the water within the water container 100 detected by the TDS sensor 700; then, when the control assembly 500 detects that the TDS value is higher than the target value, the circulation pump 400 and the filter cartridge module 200 are controlled to operate.

Through the circulation filtration processing of filter assembly 202 and/or single flow channel desalination subassembly 201 to the water in water container 100 for the TDS value of water reduces gradually, for example, the TDS value of running water is 300mg/L, after the processing through filter core module 200, the target value is 200mg/L, consequently, when the TDS value reduces to 200mg/L, control assembly 500 control circulating pump 400 is closed, and at this moment, the water in water container 100 has reached clean degree, and can not produce the incrustation scale in water container 100 after boiling water.

The target value may be a value set by the control assembly 500 in a program, or a user setting, or a stable value of the TDS of the water in the purification process.

When the TDS value is not higher than the target value, the control assembly 500 controls the heating assembly to heat the water in the water container 100, so that the water boiling function is realized.

For example, during the period when the TDS value of the water reaches the target value, the heating assembly 300 may be used as a first stage of water boiling, and when the heating assembly is in the first stage, the water in the water container 100 may be preheated according to a first heating power, and the first heating power may be 20% of the full heating power.

For example, during the time when the TDS value of the water reaches or is less than the target value, it may be used as a second stage of boiling the water, in which the control assembly 500 controls the heating assembly 300 to heat the water in the water container 100 to a preset temperature value at the second heating power, where the preset temperature value may be 100 ℃, that is, the state of boiling the water is reached. Wherein the second heating power is not less than the first heating power.

Preferably, in the second stage, the control unit 500 controls the heating unit 300 to heat at the second heating power, the first heating power may be 20% of the full heating power, and then the second heating power may be the full heating power, which may accelerate the water boiling speed.

It can be understood that TDS sensor 700, TDS pen, can not be used to measure high temperature water, for example, hot boiled water, consequently, the TDS sensor 700 of this application, with control assembly 500 electrical connection, when the temperature value that detects water reaches preset temperature value, for example 70 degrees centigrade, control assembly 500 control TDS sensor 700 stops to detect the TDS of flourishing water container 100 internal water, or when first stage ended, when the TDS value was not higher than the target value promptly, control TDS sensor stopped to the TDS of the water in the flourishing water container detects.

It should be noted that, the detected temperature value of the water reaches the preset temperature value, for example, 70 degrees centigrade, the temperature sensor 600 is set in the water container 100, the temperature sensor 600 detects the water temperature and then sends the water temperature to the control component 500, and at this time, the control component 500 controls the TDS sensor 700 to stop detecting the TDS of the water in the water container 100.

And, the TDS value obtained, the control assembly 500 controls a display screen display on the outside of the water container 100.

Illustratively, the single-channel desalination assembly 201 is removably received within the interior of the water boiling apparatus. The filter elements of the single-channel desalination assembly 201 can be removed, flushed, or replaced as needed to regenerate the filter elements of the single-channel desalination assembly 201.

The water boiling device provided by the above embodiment of this specification includes: a water container 100, a heating assembly 300, a filter cartridge module 200, a circulation pump 400, and a control assembly 500, and the control assembly 500 is connected to the heating assembly 300, the single channel desalination assembly 201 in the filter cartridge module 200, and the circulation pump 400. The TDS sensor 700 sends the detected TDS value of the water in the water container 100 to the control assembly 500, and when the TDS value of the water is higher than a target value, the control assembly 500 controls the circulation pump 400 and the filter element module 200 to work, so that the filter element module 200 can purify the water in the water container 100; when the TDS value of the water is not higher than the target value, the control assembly 500 controls the heating assembly 300 to heat the water in the water container 100, so as to realize water boiling. Because the single-channel desalination component 201 in the filter element module 200 carries out desalination treatment on the water in the water container 100 to reach a target value, and no wastewater is generated, no scale is generated after the water container 100 is boiled for many times.
