[0001] The present disclosure relates to a water treatment device using a capacitive desalination technology.

[0002] Desalination technology is widely used across industries to remove hardness components such as calcium and magnesium from water, especially in areas with high hardness. The treated water can be used for drinking, boiler water, or as cooling water for power plants and industrial facilities.

[0003] An example of a deionization technology is capacitive deionization (CDI), which removes ions by electrochemically adsorbing them on electrodes with a high specific surface area.

[0004] A capacitive desalination device may include a single channel, electrodes with high surface areas on both sides of the channel for adsorbing ions of a fluid flowing within the channel, and an ion exchange membrane for selective transport of specific ions. The capacitive desalination device may generate an electric field in a direction perpendicular to the direction of fluid flow within the channel to drive the transport of ions.

[0005] A capacitive deionizer may be incorporated into an appliance such as a dishwasher or washing machine. Dishwashers or washing machines may require hot water to improve cleaning efficiency, and therefore, dishwashers or washing machines may include a separate hot water generation device.

[0044] Water treatment devices, according to various embodiments, can purify contaminated water and make it clean. Water treatment devices are used in sewage treatment facilities, industrial processes, and water supply systems in homes and offices, playing a vital role in environmental protection and human health. Water purified by water treatment devices can be released back into the environment, used for cleaning, used as drinking water, or reused in industrial processes.

[0046] Water treatment devices can purify polluted water through various methods, including biological treatment methods, chemical treatment methods, and physical treatment methods.

[0047] A water treatment device according to one embodiment can purify contaminated water through a capacitive deionization (CDI) method.

[0048] The capacitive desalination method refers to a method of removing ions from contaminated water by adsorption and desorption of ions from the surface of electrodes due to an electrical force generated between electrodes.

[0053] In addition, the above “heating body” may also be referred to as “heating material,” “heating material,” “heating metal,” or “heating alloy.” However, it is not limited to these terms, and any term that refers to a material having heat generation performance when voltage is applied may be substituted.

[0054] In addition, in the present disclosure, the porous electrode means a porous material layer formed on a current collector of an electrode for a water treatment device, and the porous electrode may be replaced with terms such as “active material layer,” “electrode active material layer,” “porous material layer,” “porous active material layer,” and “porous electrode active material layer.”

[0055] FIG. 1 illustrates a conceptual diagram of a water treatment device according to one or more embodiments of the present disclosure.

[0056] Referring to FIG. 1, a water treatment device (1) according to one embodiment may include an ion removal module (110).

[0057] The ion removal module (110) may include a first electrode (111) and a second electrode (112). The first electrode (111) and the second electrode (112) may be arranged to face each other. The first electrode (111) and the second electrode (112) may form an electric field.

[0058] The first electrode (111) may include a first current collector (111a) and a first porous electrode (111b). The first electrode (111) may be a positive electrode (anode) or a negative electrode (cathode). The first current collector (111a) may also be referred to as a first current collecting layer or a first conductive layer, and examples of the first current collecting layer (111a) may include a graphite sheet, carbon paper or carbon cloth, a stainless steel plate, a titanium mesh or plate, nickel foam, and a copper plate.

[0059] In one embodiment, the first current collector (111a) may include a plate electrically connected to the first porous electrode (111b). The plate may include a metal plate and / or a non-metal plate.

[0060] The first current collector (111a) may include a conductor. For example, the first current collector (111a) may include graphite.

[0061] For example, the first current collector (111a) may include a material that generates heat based on the application of voltage. For example, the first current collector (111a) may include a material with high thermal resistance. The first current collector (111a) may include a heating element having heat generation performance.

[0062] The heating element may include a metal having excellent conductivity and heat generation performance so that an electric field can be uniformly distributed on the electrode surface when voltage is applied to the water treatment device (1).

[0063] The heating element is not particularly limited in type as long as it is a metal having heating performance, and may include, for example, one or more metals selected from among nickel (Ni), chromium (Cr), molybdenum (Mo), tungsten (W), platinum (Pt), titanium (Ti), tantalum (Ta), nickel-chromium alloy (NiCr), iron-chromium alloy (FeCr), iron-nickel-chromium alloy (FeNiCr), iron-cobalt-nickel alloy (FeCoNi), iron-chromium-aluminum alloy (FeCrAl), tantalum-aluminum alloy (TaAl), tin oxide (SnO), hafnium diboride (HfB2), ruthenium-chromium alloy (RuCr), iridium-chromium alloy (IrCr), and cobalt-chromium alloy (CoCr). As an example, the heating element may include one or more metals selected from among Ni, Cr, and NiCr. The heating element can be used as a single component, or it can be used in combination with other components.

[0064] The heating element may have an electrical resistivity of 10-2 to 10-4 Ωcm at room temperature. If the electrical resistivity is higher than 10-2 Ωcm, it may be difficult to form the heating element due to the excessively high resistivity, and the heating temperature may be low, making it difficult to obtain the desired heating performance. In addition, if the electrical resistivity is lower than 10-4 Ωcm, the heat generated when applying pressure may be excessively high due to the excessively low resistivity, which may be unsuitable in terms of lifespan and reliability.

[0065] The first porous electrode (111b) may comprise a solid electrode having an internal void space that enables diffusion and absorption of ions from a fluid. The first porous electrode (111b) may comprise a material having a high affinity for ion absorption. For example, the first porous electrode (111b) may comprise a carbon porous electrode.

[0066] The first porous electrode (111b) may include a thermally conductive material capable of transferring heat generated from the first current collector (111a) to the deionization channel (115). The first porous electrode (111b) may include a material capable of transferring heat generated from a heating element included in the first current collector (111a) to the deionization channel (115). The first porous electrode (111b) may include a material having a high heat transfer rate.

[0067] For example, the first porous electrode (111b) may include a carbon-based active material including at least one selected from activated carbon, graphene, carbon nanotubes, carbon fibers, and carbon aerogel. The carbon-based active material may be manufactured in powder form and used.

[0068] The carbon-based active material may have an average particle diameter of 10 μm or less. For example, in order to increase the specific surface area and capacitance of the first porous electrode (111b), a carbon-based active material having an average particle diameter of 10 nm to 10 μm may be used.

[0069] For example, the first porous electrode (111b) may have a thickness of 100 μm to 300 μm. For example, the first porous electrode (111b) may have a thickness of 150 μm to 250 μm. For example, the first porous electrode (111b) may have a thickness of 180 μm to 220 μm. When the thickness of the first porous electrode (111b) is less than 100 μm or more than 300 μm, the removal efficiency of divalent cations (Ca2+, Mg2+) included in the raw water may decrease. Considering this, the first porous electrode (111b) may be included with a thickness of 100 μm to 300 μm to reduce electrical resistance and improve desalination efficiency.

[0070] For example, the first porous electrode (111b) may be provided on one surface of the first current collector (111a) including the heating element.

[0071] The second electrode (112) may include a second current collector (112a) and a second porous electrode (112b). The second electrode (112) may be a positive electrode (anode) or a negative electrode (cathode). The second current collector (112a) may also be referred to as a second current collecting layer or a second conductive layer, and examples of the second current collecting layer (112a) may include a graphite sheet, carbon paper or carbon cloth, a stainless steel plate, a titanium mesh or plate, nickel foam, and a copper plate.

[0072] In one embodiment, the second current collector (112a) may include a plate electrically connected to the second porous electrode (112b). The plate may include a metal plate and / or a non-metal plate.

[0073] The second current collector (112a) may include a conductor. The second current collector (112a) may include the same composition as the first current collector (111a). For example, the second current collector (112a) may include graphite. In one embodiment, the second current collector (112a) may include a material different from the material of the first current collector (111a).

[0074] For example, the second current collector (112a) may include a material that generates heat based on the application of voltage. The second current collector (112a) may be used as an electrical conductor and a thermal energy source. For example, the second current collector (112a) may include a material with high thermal resistance. The second current collector (112a) may include a heating element having heat generation performance.

[0075] The heating element may include a metal having excellent conductivity and heat generation performance so that an electric field can be uniformly distributed on the electrode surface when voltage is applied to the water treatment device (1).

[0076] The heating element is not particularly limited in type as long as it is a metal having heating performance, and may include, for example, one or more metals selected from Ni, Cr, Mo, W, Pt, Ti, Ta, NiCr, FeCr, FeNiCr, FeCoNi, FeCrAl, TaAl, SnO, HfB2, RuCr, IrCr, and CoCr. For example, the heating element may include one or more metals selected from Ni, Cr, and NiCr. The heating element may be used as a single component, or may be used in combination with other components. The heating element may be implemented in various forms such as thin-film traces, wire coils, or mesh structures.

[0077] The heating element may have an electrical resistivity of 10-2 to 10-4 Ωcm at room temperature. If the electrical resistivity is higher than 10-2 Ωcm, it may be difficult to form the heating element due to the excessively high resistivity, and the heating temperature may be low, making it difficult to obtain the desired heating performance. In addition, if the electrical resistivity is lower than 10-4 Ωcm, the heat generated when applying pressure may be excessively high due to the excessively low resistivity, which may be unsuitable in terms of lifespan and reliability.

[0078] The heating element of the second current collector (112a) according to various embodiments may have the same configuration as the heating element of the first current collector (111a). However, the present invention is not limited thereto, and the heating element of the second current collector (112a) may have a different configuration from the heating element of the first current collector (111a).

[0079] A water treatment device (1) according to various embodiments may include a first current collector (111a) that generates heat based on the application of voltage, a second current collector (112a) that generates heat based on the application of voltage, and the first current collector (111a) and the second current collector (112a) that generate heat based on the application of voltage.

[0080] A water treatment device (1) according to various embodiments may include a first current collector (111a) that has a heating element having a heating performance based on the application of voltage, a second current collector (112a) that has a heating element having a heating performance based on the application of voltage, and the first current collector (111a) and the second current collector (112a) that have a heating element having a heating performance based on the application of voltage.

[0081] The second porous electrode (112b) may include a solid electrode having an internal void space that allows diffusion and absorption of ions from a fluid. The second porous electrode (112b) may include the same configuration as the first porous electrode (111b). The second porous electrode (112b) may include a material having a high affinity for ion absorption. For example, the second porous electrode (112b) may include a carbon porous electrode. In one embodiment, the second porous electrode (112b) may include a material different from the material of the first porous electrode (111b).

[0082] The second porous electrode (112b) may include a thermally conductive material capable of transferring heat generated from the second current collector (112a) to the deionization channel (115). The second porous electrode (112b) may include a material capable of transferring heat generated from a heating element included in the second current collector (112a) to the deionization channel (115). The second porous electrode (112b) may include a material having a high heat transfer rate.

[0083] For example, the second porous electrode (112b) may include a carbon-based active material including at least one selected from activated carbon, graphene, carbon nanotubes, carbon fibers, and carbon aerogel. The carbon-based active material may be manufactured in powder form and used.

[0084] The carbon-based active material may have an average particle diameter of 10 μm or less. For example, in order to increase the specific surface area and capacitance of the second porous electrode (112b), a carbon-based active material having an average particle diameter of 10 nm to 10 μm may be used.

[0085] For example, the second porous electrode (112b) may have a thickness of 100 μm to 300 μm. For example, the second porous electrode (112b) may have a thickness of 150 μm to 250 μm. For example, the second porous electrode (112b) may have a thickness of 180 μm to 220 μm. When the thickness of the second porous electrode (112b) is less than 100 μm or more than 300 μm, the removal efficiency of divalent cations (Ca2+, Mg2+) contained in the raw water may be reduced. Considering this, the second porous electrode (112b) may be included with a thickness of 100 μm to 300 μm to reduce electrical resistance and improve desalination efficiency.

[0086] For example, the second porous electrode (112b) may be provided on one surface of the second current collector (112a) including the heating element.

[0087] The ion removal module (110) may include an anion exchange membrane (111c) that selectively allows the passage of anions while blocking cations. The anion exchange membrane (111c) may include a membrane that allows only anions to pass through among cations and anions. Since the anion exchange membrane (111c) has a positive charge, it repels cations and does not allow only anions to pass through. For example, the anion exchange membrane (111c) may include a polymer matrix having a quaternary ammonium functional group embedded therein to impart a positive charge to the membrane structure. The positive charge repels cations and attracts anions, thereby enabling electroselective transport.

[0088] The ion removal module (110) may include an anion channel (116) formed between a first current collector (111a) and an anion exchange membrane (111c). The anion channel (116) may include a space between the first current collector (111a) and the anion exchange membrane (111c). A first porous electrode (111b) may be provided in the anion channel (116).

[0089] The ion removal module (110) may include a cation exchange membrane (112c) that selectively allows the passage of cations while blocking anions. The cation exchange membrane (112c) may include a membrane that allows only cations to pass among cations and anions. The cation exchange membrane (112c) has a negative charge, so it repels anions and does not allow them to pass, but only allows cations to pass.

[0090] The ion removal module (110) may include a cation channel (117) formed between a second current collector (112a) and a cation exchange membrane (112c). The cation channel (117) may include a space between the second current collector (112a) and the cation exchange membrane (112c). A second porous electrode (112b) may be provided in the cation channel (117).

[0091] The anion exchange membrane (111c) and the cation exchange membrane (112c) may include an ion-selective permeable membrane that allows fluid and target ions to pass through while maintaining the separation of ionic species. For example, the anion exchange membrane (111c) and the cation exchange membrane (112c) may include a synthetic resin membrane.

[0092] The ion removal module (110) may include a deionization channel (115). The deionization channel (115) may be formed between an anion exchange membrane (111c) and a cation exchange membrane (112c). The deionization channel (115) may include a space between the anion exchange membrane (111c) and the cation exchange membrane (112c). The first electrode (111) may be disposed on one side of the deionization channel (115), and the second electrode (112) may be disposed on the other side opposite to one side of the deionization channel (115).

[0093] Since the anion channel (116), the cation channel (117), and the deionization channel (115) can be separated from each other by ion exchange membranes (111c, 112c), terms such as compartment, space, room, or chamber may be substituted.

[0094] The anion channel (116), the cation channel (117), and the deionization channel (115) may be fluidically connected to each other, allowing fluid communication therebetween. For example, a fluid in the deionization channel (115) may flow into the anion channel (116) and / or the cation channel (117), and conversely, a fluid in the anion channel (116) and / or the cation channel (117) may flow into the deionization channel (115).

[0095] When a positive voltage is applied to the first current collector (111a), the first electrode (111) becomes a positive electrode (anode), and when a negative voltage is applied to the second current collector (112a), the second electrode (112) becomes a negative electrode (cathode). Accordingly, when a positive voltage is applied to the first current collector (111a) and a negative voltage is applied to the second current collector (112a), the cations in the deionization channel (115) can move to the cation channel (117), and the anions in the deionization channel (115) can move to the anion channel (116).

[0096] When a positive voltage is applied to the first current collector (111a), the negative ions moved to the negative ion channel (116) can be adsorbed to the first porous electrode (111b), and when a negative voltage is applied to the second current collector (112a), the positive ions moved to the positive ion channel (117) can be adsorbed to the second porous electrode (112b).

[0097] By applying a positive voltage to the first current collector (111a) and a negative voltage to the second current collector (112a), heat may be generated in the first current collector (111a) and / or the second current collector (112a). The heat generated in the first current collector (111a) may be transferred to the deionization channel (115) through the first porous electrode (111b). The heat generated in the second current collector (112a) may be transferred to the deionization channel (115) through the second porous electrode (112b).

[0098] Heat transferred to the deionization channel (115) can be transferred to water passing through the deionization channel (115). Heat provided to the deionization channel (115) can heat water passing through the deionization channel (115).

[0099] Applying a positive voltage to the first current collector (111a) and applying a negative voltage to the second current collector (112a) may include making the potential of the first current collector (111a) higher than the potential of the second current collector (112a).

[0100] Applying a positive voltage to the first collector (111a) may include applying a negative voltage to the second collector (112a).

[0101] Applying a positive voltage to the first current collector (111a) and a negative voltage to the second current collector (112a) may include applying a positive voltage between the first current collector (111a) and the second current collector (112a).

[0102] Applying a positive voltage between the first current collector (111a) and the second current collector (112a) may include making the potential of the first current collector (111a) higher than the potential of the second current collector (112a).

[0103] When a negative voltage is applied to the first current collector (111a), the first electrode (111) becomes a negative electrode (cathode), and when a positive voltage is applied to the second current collector (112a), the second electrode (112) becomes a positive electrode (anode). Accordingly, when a negative voltage is applied to the first current collector (111a) and a positive voltage is applied to the second current collector (112a), cations in the cation channel (117) can move to the deionization channel (115), and anions in the anion channel (116) can move to the deionization channel (115).

[0127] Hereinafter, a method for manufacturing a water treatment device (1) according to one embodiment of the present disclosure will be described in detail.

[0128] A method for manufacturing a water treatment device (1) according to one embodiment of the present disclosure may include a step of forming a first electrode (111) or a second electrode (112) by applying a carbon-based active material to at least one of both surfaces of the first current collector (111a) or the second current collector (112a) including a heating element, in a water treatment device (1) including a first electrode (111) including a first current collector (111a) and a first porous electrode (111b), a second electrode (112) including a second current collector (112a) and a second porous electrode (112b), and a deionization channel (115) formed between the first electrode (111) and the second electrode (112).

[0129] The heating element of the first current collector (111a) and / or the second current collector (112a) may include one or more metals selected from Ni, Cr, Mo, W, Pt, Ti, Ta, NiCr, FeCr, FeNiCr, FeCoNi, FeCrAl, TaAl, SnO, HfB2, RuCr, IrCr, and CoCr as described above. For example, the heating element of the first current collector (111a) and / or the second current collector (112a) may include one or more metals selected from Ni, Cr, and NiCr. In addition, the heating element of the first current collector (111a) and / or the second current collector (112a) may have an electrical resistivity of 10-2 to 10-4 Ωcm at room temperature.

[0130] The porous electrode (111b, 112b) may be formed on the current collector (111a, 112a) and may be formed, for example, by using a method such as spraying, dip coating, knife casting, doctor blade, or spin coating. At this time, the porous electrode (111b, 112b) may be formed on the current collector (111a, 112a) with a thickness of 100 μm to 300 μm in order to reduce electrical resistance and improve desalination efficiency.

[0131] The carbon-based active material may include one or more selected from activated carbon, graphene, carbon nanotubes, carbon fibers, and carbon aerogel. For example, the carbon-based active material may be applied one or more times to form a desired thickness.

[0132] In addition, the porous electrode (111b, 112b) can be formed in the heating element by applying voltage to a solution containing the heating element and the carbon-based active material.

[0133] For example, when a voltage is applied to a solution containing a heating element, a carbon-based active material, and a solvent to perform electrophoretic deposition (EPD), the heating element metal is eluted in a cationic state by a side effect during the EPD process, and the metal eluted in a cationic state and the carbon-based active material contained in the solution form cross-links to form a porous electrode on the surface of the heating element.

[0134] At this time, the carbon-based active material may include at least one selected from activated carbon, graphene, carbon nanotubes, carbon fibers, and carbon aerogels, and the carbon-based material may have a hydroxyl group, a carboxyl group, etc. to have a negative charge for bonding with the heating element metal eluted in a cationic state.

[0135] The water treatment device (1) according to one embodiment of the present disclosure as described above can efficiently remove divalent cations contained in raw water through the first porous electrode (111b) or the second porous electrode (112b) to soften the water, and at the same time, can warm the softened water by the heating element contained in the first current collector (111a) or the second current collector (112a), thereby enabling the supply of hot water to the applied home appliance and enhancing the cleaning and washing effect.

[0138] In one embodiment, an electrode for a water treatment device according to the present disclosure can be prepared by dissolving polyvinylidene fluoride in dimethylacetamide, mixing graphene oxide, and stirring to prepare an electrode slurry. The prepared electrode slurry can be cast onto a NiCr alloy current collector using a doctor blade, and then dried in a drying oven to form an electrode having a thickness of 100 μm to 300 μm.

[0139] In another embodiment, the electrode for a water treatment device according to the present disclosure can be prepared by dissolving graphene oxide in dimethylacetamide, placing a NiCr alloy mesh into the solution, and applying a voltage to perform an electrophoretic deposition process. At this time, the pH of the solution is 7, and the voltage is controlled to -0.5 to -2 V to induce the elution of Ni+ ions from the NiCr alloy mesh, thereby manufacturing an electrode for a water treatment device in which graphene oxide is bonded to the surface of the NiCr alloy mesh (Fig. 2). As a result of taking an SEM (Scanning Electron Microscope) image of the electrode, it can be confirmed that, as shown in Figs. 3 and 4, the electrode for a water treatment device according to another embodiment of the present disclosure has an electrode having a porous structure formed on the NiCr surface. The electrodes illustrated in Figs. 3 and 4 may correspond to the first electrode (111) and / or the second electrode (112) of Fig. 5.

[0147] Through the operation mode selection input interface, the operator of the water treatment device (1) can select the operation mode to be started first among the operation modes of the water treatment device (1).

[0148] The setting input interface may include an interface for setting setting values ​​for various components of the water treatment device (1), such as pump (16) and electrodes (111, 112).

[0150] At least one output interface (42) can transmit various information related to the operation of the water treatment device (1) to the user by generating sensory information.

[0155] The water quality sensor may be provided in the second flow path (22), the third flow path (23), and / or the fourth flow path (24) to detect the water quality of water discharged through the module discharge portion (103), but any location for sensing the water quality of water discharged from the ion removal module (110) may be employed as the location of the water quality sensor without limitation.

[0156] Information acquired by the sensor unit (50) can be transmitted to the control unit (70).

[0157] Information acquired by the sensor unit (50) may also be output through the output interface (42).

[0158] The water treatment device (1) may include a communication unit (60) for communicating with an external device (e.g., a server, a user device, and / or a home appliance) via wires and / or wirelessly.

[0159] The communication unit (60) may include at least one of a short-range communication module or a long-range communication module.

[0161] To this end, the communication unit (60) can support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between external devices, and the performance of communication through the established communication channel. According to one embodiment, the communication unit (60) can include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with the external device through a first network (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These different types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips).

[0162] The short-range wireless communication module may include, but is not limited to, a Bluetooth communication module, a BLE (Bluetooth Low Energy) communication module, a near field communication module, a WLAN (Wi-Fi) communication module, a Zigbee communication module, an infrared (IrDA, infrared Data Association) communication module, a WFD (Wi-Fi Direct) communication module, an UWB (ultrawideband) communication module, an Ant+ communication module, a microwave (uWave) communication module, etc.

[0164] In one embodiment, the communication unit (60) can communicate with external devices such as a server, user devices, and home appliances through a surrounding access point (AP).

[0165] The communication unit (60) can receive information on the water quality of water discharged through the module discharge unit (103) from an external device.

[0166] For example, if a sensor for detecting the water quality of water discharged through the module discharge portion (103) is installed outside the water treatment device (1), the communication unit (60) can receive information about the water quality of water discharged through the module discharge portion (103) from the sensor installed outside the water treatment device (1).

[0167] Information acquired by the communication unit (60) can be transmitted to the control unit (70).

[0168] The communication unit (60) can transmit information on water quality obtained from the sensor unit (50) to an external device (e.g., server, user device, home appliance).

For example, the control unit (70) can control the voltage applied to the first electrode (111) and the second electrode (112).

[0170] The control unit (70) may include hardware such as a CPU, Micom, or memory, and software such as a control program.

At least one valve (30) can include a first opening / closing device (30a) and / or a second opening / closing device (30b).

[0174] FIG. 6 is a conceptual diagram for explaining the movement of ions and the temperature change of water that occur when a water treatment device according to one or more embodiments performs deionization operation.

[0175] Referring to FIG. 6, the control unit (70) can control the power supply (80) to apply a negative voltage to the second collector (112a) and a positive voltage to the first collector (111a) in the deionization operation. The power supply (80) can be a bipolar power supply configured to provide a dual polarity output, or a programmable power supply controllable by a software program executed by the control unit (70). In addition to the processor (71) and memory (72) illustrated in FIG. 5, the control unit (70) can include a microcontroller (MCU) configured to output a control signal, such as a logic high / low signal or a pulse width modulation (PWM) signal, based on an input from the processor (71). The control unit (70) may also include a logic controller such as logic gates or flip-flops, a field programmable gate array (FPGA) based controller, or a complex programmable logic device (CPLD) based controller.

[0176] When a negative voltage is applied to the second collector (112a), the cations contained in the water in the deionization channel (115) can move to the cation channel (117).

[0177] Cations contained in water may include, for example, sodium ions (Na+), magnesium ions (Mg2+), calcium ions (Ca2+), etc.

[0178] Cations contained in water within the deionization channel (115) can be adsorbed onto the second porous electrode (112b) by moving to the cation channel (117).

[0179] Accordingly, when the water treatment device (1) performs deionization operation, cations in the water in the deionization channel (115) can be removed.

[0180] A negative voltage can be applied to the second collector (112a), and a positive voltage can be applied to the first collector (111a).

[0181] When a positive voltage is applied to the first collector (111a), the negative ions contained in the water in the deionization channel (115) can move to the negative ion channel (116).

[0182] When a positive voltage is applied to the first current collector (111a) and a negative voltage is applied to the second current collector (112a), heat may be generated in the first current collector (111a) and / or the second current collector (112a). The heat generated in the first current collector (111a) may be transferred to the deionization channel (115) through the first porous electrode (111b). The heat generated in the second current collector (112a) may be transferred to the deionization channel (115) through the second porous electrode (112b). Water passing through the deionization channel (115) may be heated by the heat transferred to the deionization channel (115).

[0183] Based on the application of a positive voltage to the first collector (111a) and a negative voltage to the second collector (112a), the ion removal module (110) of the water treatment device (1) can remove ions from water passing through the deionization channel (115) and heat the water passing through the deionization channel (115).

[0184] According to this configuration, the water treatment device (1) according to one embodiment of the present disclosure can remove cations contained in water and heat water even without a separate heating device.

[0185] In addition, the water treatment device (1) according to one embodiment of the present disclosure can heat water passing through a deionization channel (115), and as the water is heated, ion mobility increases, so ion removal efficiency can be improved.

[0186] According to one embodiment of the present disclosure, when voltage is applied to the water treatment device (1), the heating element of the first current collector (111a) and / or the second current collector (112a) generates heat due to the heating properties of the heating element, and the generated heat is transferred to the water flowing into the ion removal module (110) of the water treatment device (1), thereby increasing the water temperature. That is, the heating element of the first current collector (111a) and / or the second current collector (112a) can have heat generation capability and thermal conductivity when voltage is applied to the ion removal module (110) of the water treatment device (1), so that low-temperature hard water can be supplied as high-temperature soft water through the water treatment device (1) without a separate heating device for warming the water.

[0187] Since the magnitude of the positive voltage applied to the first collector (111a) in the deionization operation is preset within a range in which water in the anion channel (116) is not electrolyzed, electrolysis of water does not occur at the first electrode (111), which is the anode.

[0188] The absence of electrolysis of water may indicate that the reaction rate of the electrolysis reaction of water is significantly slow, so that electrolysis of water hardly occurs.

[0189] FIG. 7 illustrates a conceptual diagram of a water treatment device according to one or more embodiments of the present disclosure.

[0190] Referring to FIG. 7, a water treatment device (2) according to one embodiment of the present disclosure will be described. Components identical to those of the water treatment device (1) illustrated in FIG. 1 are assigned the same reference numerals, and detailed descriptions thereof may be omitted.

[0191] A water treatment device (2) according to one embodiment of the present disclosure may include an ion removal module (110). When a fluid passes through a deionization channel (115) of the ion removal module (110), its flow rate may vary depending on its relative position with respect to the first electrode (111) and the second electrode (112). Specifically, the fluid may have a relatively fast flow rate in a region further away from the first electrode (111) and the second electrode (112), and a relatively slow flow rate in a region closer to the first electrode (111) and the second electrode (112). In addition, relatively less heat energy is transferred to the central portion of the deionization channel (115) that is further away from the first electrode (111) and the second electrode (112) compared to the side portion of the deionization channel (115) that is closer to the first electrode (111) or the second electrode (112). Accordingly, the fluid passing through the portion close to the first electrode (111) or the second electrode (112) can be heated relatively quickly, while the fluid passing through the center can be heated relatively slowly. Accordingly, the temperature of the fluid passing through the portion close to the first electrode (111) or the second electrode (112) can be higher than the temperature of the fluid passing through the portion spaced apart from the first electrode (111) and the second electrode (112).

[0192] In addition, as the fluid passing through the side of the deionization channel (115) close to the first electrode (111) or the second electrode (112) is heated by the first electrode (111) or the second electrode (112), the temperature difference between the first electrode (111) and the second electrode (112) is reduced, and thus, heat transfer from the first electrode (111) and the second electrode (112) to the deionization channel (115) can be reduced.

[0193] Referring to FIG. 7, a water treatment device (2) according to one embodiment of the present disclosure may include a flow changer (131). The flow changer (131) may be an internal structure disposed within the deionization channel (115) to disturb laminar flow, promote mixing, and equalize a temperature gradient across the fluid flow by redistributing hotter and colder fluid regions. The flow changer (131) may be a static structure fixed to a specific location within the deionization channel (115), or may be a movable structure that can float and move together with the fluid within the deionization channel (115). The flow changer (131) may be arranged to reduce a temperature difference between a fluid passing through a portion close to the first electrode (111) or the second electrode (112) and a fluid passing through a portion spaced from the first electrode (111) and the second electrode (112). The flow change unit (131) may be provided to reduce the temperature difference between the fluid passing through the side portion of the deionization channel (115) and the fluid passing through the central portion of the deionization channel (115).

[0194] The flow changing unit (131) according to one embodiment of the present disclosure may be arranged so that the fluid flowing through the central portion of the deionization channel (115) is mixed with the fluid flowing through one side portion of the deionization channel (115) close to the first electrode (111) or the fluid flowing through one side portion of the deionization channel (115) close to the second electrode (112). The flow changing unit (131) may be arranged so as to guide the fluid flowing through the central portion of the deionization channel (115) to one side portion of the deionization channel (115) close to the first electrode (111) or to one side portion of the deionization channel (115) close to the second electrode (112).

[0195] The flow change unit (131) may be provided to change the linear flow of the fluid passing through the deionization channel (115) into a turbulent flow. The flow change unit (131) may be provided to cause turbulence to occur inside the deionization channel (115) while the fluid passes through the deionization channel (115).

[0196] For example, the flow change unit (131) may be placed inside the deionization channel (115). The flow change unit (131) may be located in the central portion of the deionization channel (115). The flow change unit (131) may be located midway between the first electrode (111) and the second electrode (112). The flow change unit (131) may be positioned so that the distance between the first electrode (111) and the second electrode is the same as the distance between the second electrode.

[0197] For example, the flow change unit (131) may include a first guide surface (131a) that gets closer to the first electrode (111) as the fluid passing through the deionization channel (115) flows, and a second guide surface (131b) that gets closer to the second electrode (112) as the fluid passing through the deionization channel (115) flows. The first guide surface (131a) may guide the fluid flowing from the center of the deionization channel (115) to one side portion closer to the first electrode (111). The second guide surface (131b) may guide the fluid flowing from the center of the deionization channel (115) to one side portion closer to the second electrode (112). For example, the flow change unit (131) may have a triangular cross-section parallel to the direction in which the fluid flows through the deionization channel (115).

[0198] For example, the flow change member (131) may include a heat-resistant material. The flow change member (131) may include a material that can withstand the temperature of water heated while passing through the deionization channel (115). For example, the flow change member (131) may include a material that does not dissolve in water.

[0199] In a water treatment device (2) according to one embodiment of the present disclosure, while the fluid passes through the deionization channel (115), the temperature of the fluid passing through the central portion becomes lower than the temperature of the fluid passing through the side portion near the first electrode (111) or the second electrode (112). Since the flow change unit (131) can guide the fluid so that the fluid passing through the central portion of the deionization channel (115) and the fluid passing through the side portion are mixed, the temperature difference of the fluid passing through the deionization channel (115) can be reduced.

[0200] Meanwhile, the fluid passing through the deionization channel (115) of the ion removal module (110) has a relatively fast flow rate as it gets farther away from the cation exchange membrane (112c) and the anion exchange membrane (111c), and a relatively slow flow rate as it gets closer to the cation exchange membrane (112c) and the anion exchange membrane (111c). Therefore, among the fluids passing through the deionization channel (115), the fluid passing through the part close to the cation exchange membrane (112c) or the anion exchange membrane (111c) undergoes ion removal relatively quickly, and the fluid passing through the part spaced apart from the cation exchange membrane (112c) and the anion exchange membrane (111c) undergoes ion removal relatively slowly. Accordingly, among the fluids passing through the deionization channel (115), the ion concentration of the fluid passing through the portion close to the cation exchange membrane (112c) or the anion exchange membrane (111c) may be lower than the ion concentration of the fluid passing through the portion spaced apart from the cation exchange membrane (112c) and the anion exchange membrane (111c).

[0201] The water treatment device (2) according to one embodiment of the present disclosure includes a flow changer (131) provided in the deionization channel (115), and thus can reduce the difference in ion concentration of a fluid passing through a portion close to a cation exchange membrane (112c) or an anion exchange membrane (111c) and an ion concentration of a fluid passing through a portion spaced apart from the cation exchange membrane (112c) and an anion exchange membrane (111c). The flow changer (131) is provided so that a fluid flowing through a central portion of the deionization channel (115) is mixed with a fluid flowing through one side portion of the deionization channel (115) close to the first electrode (111) or a fluid flowing through one side portion of the deionization channel (115) close to the second electrode (112), and thus can reduce the difference in ion concentration of a fluid passing through the deionization channel (115).

The flow changing unit (132) may be arranged so as to guide the fluid flowing through the central portion of the deionization channel (115) to one side portion of the deionization channel (115) close to the first electrode (111) or to one side portion of the deionization channel (115) close to the second electrode (112).

[0206] The flow change unit (132) may be provided to change the linear flow of the fluid passing through the deionization channel (115) into a turbulent flow. The flow change unit (132) may be provided to cause turbulence to occur inside the deionization channel (115) while the fluid passes through the deionization channel (115).

[0207] A flow changing unit (132) according to one embodiment of the present disclosure may be disposed inside a deionization channel (115). The flow changing unit (132) may include a first changing part (132a) positioned at a central portion of the deionization channel (115). For example, the first changing part (132a) may be positioned midway between the first electrode (111) and the second electrode (112). The first changing part (132a) may be positioned such that a distance from the first electrode (111) is the same as a distance from the second electrode. For example, the first changing part (132a) may be provided such that a cross-section parallel to the direction in which the fluid flows in the deionization channel (115) has a circular or elliptical shape.

[0208] For example, the first change part (132a) may include a heat-resistant material. The first change part (132a) may include a material that can withstand the temperature of water heated while passing through the deionization channel (115). For example, the first change part (132a) may include a material that is insoluble in water.

[0209] A flow change unit (132) according to one embodiment of the present disclosure may include a second change part (132b) disposed between a first change part (132a) and a first electrode (111) in a deionization channel (115). For example, the second change part (132b) may have the same configuration as the first change part (132a). For example, the second change part (132b) may include a plurality of parts.

[0210] A flow change unit (132) according to one embodiment of the present disclosure may include a third change part (132c) disposed between a first change part (132a) and a second electrode (112) in a deionization channel (115). For example, the third change part (132c) may have the same configuration as the first change part (132a). For example, the third change part (132c) may include a plurality of parts.

[0211] For example, the first change part (132a), the second change part (132b), and the third change part (132c) may be aligned along the direction from the first electrode (111) toward the second electrode (112). The first change part (132a) may be spaced apart from the second change part (132b) and / or the third change part (132c). The fluid passing through the deionization channel (115) may pass through the space between the first change part (132a) and the second change part (132b), and may also pass through the space between the first change part (132a) and the third change part (132c).

[0212] In a water treatment device (3) according to one embodiment of the present disclosure, while the fluid passes through the deionization channel (115), the temperature of the fluid passing through the central portion becomes lower than the temperature of the fluid passing through the side portion near the first electrode (111) or the second electrode (112). Since the flow change unit (132) can guide the fluid so that the fluid passing through the central portion of the deionization channel (115) and the fluid passing through the side portion are mixed, the temperature difference of the fluid passing through the deionization channel (115) can be reduced.

[0213] The water treatment device (3) according to one embodiment of the present disclosure includes a flow changer (132) provided in the deionization channel (115), and thus can reduce the difference in ion concentration of a fluid passing through a portion close to a cation exchange membrane (112c) or an anion exchange membrane (111c) and an ion concentration of a fluid passing through a portion spaced apart from the cation exchange membrane (112c) and an anion exchange membrane (111c). The flow changer (132) is provided so that a fluid flowing through a central portion of the deionization channel (115) is mixed with a fluid flowing through one side portion of the deionization channel (115) close to the first electrode (111) or a fluid flowing through one side portion of the deionization channel (115) close to the second electrode (112), and thus can reduce the difference in ion concentration of a fluid passing through the deionization channel (115).

[0214] FIG. 9 illustrates a conceptual diagram of a water treatment device according to one or more embodiments of the present disclosure.

[0215] Referring to FIG. 9, a water treatment device (4) according to one embodiment of the present disclosure will be described. Components identical to those of the water treatment device (1) illustrated in FIG. 1 are assigned the same reference numerals, and detailed descriptions thereof may be omitted.

[0216] Referring to FIG. 9, a water treatment device (4) according to one embodiment of the present disclosure may include a flow changer (133). The flow changer (133) may be provided to reduce the temperature difference between a fluid passing through a portion close to the first electrode (111) or the second electrode (112) and a fluid passing through a portion spaced from the first electrode (111) and the second electrode (112). The flow changer (133) may be provided to reduce the temperature difference between a fluid passing through a side portion of a deionization channel (115) and a fluid passing through a central portion of the deionization channel (115).

[0217] The flow changing unit (133) according to one embodiment of the present disclosure may be arranged so that the fluid flowing through the central portion of the deionization channel (115) is mixed with the fluid flowing through one side portion of the deionization channel (115) close to the first electrode (111) or the fluid flowing through one side portion of the deionization channel (115) close to the second electrode (112). The flow changing unit (133) may be arranged so as to guide the fluid flowing through the central portion of the deionization channel (115) to one side portion of the deionization channel (115) close to the first electrode (111) or to one side portion of the deionization channel (115) close to the second electrode (112).

[0218] The flow change unit (133) may be provided to change the linear flow of the fluid passing through the deionization channel (115) into a turbulent flow. The flow change unit (133) may be provided to cause turbulence to occur inside the deionization channel (115) while the fluid passes through the deionization channel (115).

[0219] A flow change unit (133) according to one embodiment of the present disclosure may be disposed inside a deionization channel (115). The flow change unit (133) may include a first change part (133a) disposed adjacent to a first electrode (111) in the deionization channel (115), and a second change part (133b) disposed adjacent to a second electrode (112).

[0220] The first change part (133a) may extend from the first electrode (111) toward the second electrode (112). The first change part (133a) may extend from the anion exchange membrane (111c). The first change part (133a) may extend from a side portion adjacent to the first electrode (111) of the deionization channel (115) toward the center portion of the deionization channel (115). The first change part (133a) may extend in a direction perpendicular to the direction in which the fluid passes through the deionization channel (115).

[0221] The second change part (133b) may extend from the second electrode (112) toward the first electrode (111). The second change part (133b) may extend from the cation exchange membrane (112c). The second change part (133b) may extend from the side portion adjacent to the second electrode (112) of the deionization channel (115) toward the center portion of the deionization channel (115). The second change part (133b) may extend in a direction perpendicular to the direction in which the fluid passes through the deionization channel (115).

[0222] The fluid flowing through the deionization channel (115) can pass through the space formed between the first change part (133a) and the second change part (133b). Among the fluids flowing through the deionization channel (115), the fluid flowing through the side portion adjacent to the first electrode (111) and the fluid flowing through the side portion adjacent to the second electrode (112) can be guided to the central portion of the deionization channel (115) by the flow change part (133). The fluid flowing through the side portion of the deionization channel (115) and the fluid flowing through the central portion can pass through the space formed between the first change part (133a) and the second change part (133b) and be mixed.

[0223] For example, the flow change member (133) may include a heat-resistant material. The flow change member (133) may include a material that can withstand the temperature of water that passes through the deionization channel (115) and is heated. For example, the flow change member (133) may include a material that is insoluble in water (e.g., a material that is insoluble in water). For example, the flow change member (133) may have a plate shape or a rod shape.

[0224] In a water treatment device (4) according to one embodiment of the present disclosure, while the fluid passes through the deionization channel (115), the temperature of the fluid passing through the central portion becomes lower than the temperature of the fluid passing through the side portion near the first electrode (111) or the second electrode (112). Since the flow change unit (133) can guide the fluid so that the fluid passing through the central portion of the deionization channel (115) and the fluid passing through the side portion are mixed, the temperature difference of the fluid passing through the deionization channel (115) can be reduced.

[0225] The water treatment device (4) according to one embodiment of the present disclosure includes a flow changer (133) provided in the deionization channel (115), and thus can reduce the difference in ion concentration of the fluid passing through a portion close to the cation exchange membrane (112c) or the anion exchange membrane (111c) and the ion concentration of the fluid passing through a portion spaced apart from the cation exchange membrane (112c) and the anion exchange membrane (111c). The flow changer (133) is provided so that the fluid flowing through the central portion of the deionization channel (115) is mixed with the fluid flowing through one side portion of the deionization channel (115) close to the first electrode (111) or the fluid flowing through one side portion of the deionization channel (115) close to the second electrode (112), and thus can reduce the difference in ion concentration of the fluid passing through the deionization channel (115).

[0226] The flow modifier (133) may be implemented in various forms, including but not limited to those illustrated in FIGS. 7 to 9. For example, the flow modifier (133) may take the form of a perforated plate that enhances turbulence while minimizing flow resistance, a rod-shaped structure that simplifies fluid flow, a triangular fin shape that promotes lateral mixing, or a spiral structure that is configured to induce turbulent flow.

[0227] FIG. 10 illustrates a conceptual diagram of a water treatment device according to one or more embodiments of the present disclosure.

[0228] Referring to FIG. 10, a water treatment device (5) according to one embodiment of the present disclosure will be described. Components identical to those of the water treatment device (1) illustrated in FIG. 1 are assigned the same reference numerals, and detailed descriptions thereof may be omitted.

[0229] Referring to FIG. 10, a water treatment device (5) according to one embodiment of the present disclosure may include an ion removal device (501). The ion removal device (501) may include at least one first ion removal module (110) and at least one second ion removal module (120). At least one first ion removal module (110) may include the same configuration as the ion removal module (110) illustrated in FIG. 1.

[0230] At least one second ion removal module (120) may include a configuration substantially identical to that of the ion removal module (110) illustrated in FIG. 1. For example, the material of the third current collector of the third electrode (121) and / or the fourth current collector of the fourth electrode (122) of the at least one second ion removal module (120) may be provided to be different from the material of the first current collector (111a) of the first electrode (111) and the second current collector (112a) of the second electrode (112) of the ion removal module (110) illustrated in FIG. 1.

For example, the path adjuster (509) may include a valve or a switch.

[0240] Referring to FIG. 10, a water treatment device (5) according to one embodiment of the present disclosure can control the temperature of water discharged from an ion removal device (501) by controlling the voltage applied to the ion removal device (501).

[0241] For example, the water treatment device (5) can provide relatively high-temperature soft water by controlling the path control device (509) so that the control unit (70) guides the water flowing into the water treatment device (5) to the first module inlet (502a). For example, the control unit (70) can control the amount of high-temperature soft water provided by controlling the path control device (509) so that the water flowing into the water treatment device (5) is guided to some of the first module inlets (502a) among the plurality of first module inlets (502a).

[0242] For example, the water treatment device (5) can provide relatively low-temperature soft water by controlling the path control device (509) so that the control unit (70) guides the water flowing into the water treatment device (5) to the second module inlet (502b). For example, the control unit (70) can control the amount of low-temperature soft water provided by controlling the path control device (509) so that the water flowing into the water treatment device (5) is guided to some of the second module inlets (502b) among the plurality of second module inlets (502b).

[0243] For example, the water treatment device (5) can provide soft water of relatively intermediate temperature by controlling the path control device (509) so that the control unit (70) guides a portion of the water flowing into the water treatment device (5) to the first module inlet (502a) and guides another portion to the second module inlet (502b). For example, the control unit (70) can control the temperature of the provided soft water by controlling the path control device (509) so that a portion of the water flowing into the water treatment device (5) is guided to two first module inlets (502a) and another portion is guided to one second module inlet (502b). For example, the control unit (70) can control the temperature of the provided soft water by controlling the path control unit (509) to guide a portion of the water flowing into the water treatment device (5) to one first module inlet (502a) and guide another portion to two second module inlets (502b).

[0244] FIG. 11 illustrates a conceptual diagram of a water treatment device according to one or more embodiments of the present disclosure.

[0245] Referring to FIG. 11, a water treatment device (6) according to one embodiment of the present disclosure will be described. The same components as those of the water treatment device (1) illustrated in FIG. 1 and the water treatment device (5) illustrated in FIG. 10 are assigned the same reference numerals, and detailed descriptions thereof may be omitted.

[0246] Referring to FIG. 11, the water treatment device (6) may include flow path adjusters (141, 142). The flow path adjusters (141, 142) may be configured to adjust the size of the deionization channels (115, 125). The flow path adjusters (141, 142) may be provided in the ion removal device (601).

[0247] For example, the euro regulator (141, 142) may include an electrostrictive material or a magnetostrictive material. The electrostrictive material may include a ceramic material such as PZT, and since its size is deformed when current is applied, when voltage is applied, its size expands and the size of the deionization channel (115, 125) can be reduced. The magnetostrictive material may include a material such as nickel, an alloy of iron and cobalt, an alloy of iron and aluminum, or zinc ferrite, and its size expands and contracts depending on whether or not a magnet is applied, so that the size of the deionization channel (115, 125) can be controlled in the same manner as described above.
