  The water treatment apparatus 100 according to an embodiment of the present invention may include a supply unit 200, a filtration unit 300, and a discharge unit 400.

  The supply unit 200 can supply raw water. To that end, the supply unit 200 may include a raw water tank 210 as shown in FIG. The raw water tank 210 can store raw water.

  For example, the user can bring the empty raw water tank 210 to a raw water source (not shown), such as a tap, and store the raw water of the raw water source in the raw water tank 210. Then, the user can attach the raw water tank 210 to the water treatment apparatus 100 and connect the raw water tank 210 in which the raw water is stored to the raw water line LRW included in the water treatment apparatus 100.

  However, the supply unit 200 is not particularly limited, and may be the above-described raw water supply source, and may be any known one as long as it can supply the raw water.

  The raw water tank 210 may be connected to the filtration unit 300 via a raw water line LRW. For example, the raw water tank 210 may be connected to the below-mentioned pretreatment filter 320 included in the filtration unit 300 via the raw water line LRW, and may be connected to the filtration unit 300.

  And as shown in FIG. 1, the raw water line LRW can include a pressure pump P and a pressure reducing valve VR. The raw water stored in the raw water tank 210 can be supplied to the pretreatment filter 320 of the filtration unit 300 at a predetermined pressure by the operation of the pressure pump P and the pressure reducing valve VR.

  The raw water tank 210 can be sterilized by the sterilizing water generated by the later-described ion exchange filter 310 included in the filtration unit 300.

  The supply unit 200 may include a regeneration tank 220 in addition to the raw water tank 210 described above. In the regeneration tank 220, as shown in FIG. 4, the regenerated water having passed through the ion exchange filter 310 can be collected at the time of regeneration of the ion exchange filter 310 included in the filtration unit 300.

  Also, when a predetermined amount of regenerated water is collected in the regeneration tank 220, the user can separate the regeneration tank 220 from the water treatment apparatus 100 and discard the regenerated water collected in the regeneration tank 220.

  The filtration unit 300 can filter the raw water supplied from the supply unit 200. To that end, the filtration unit 300 can include an ion exchange filter 310.

  The ion exchange filter 310 can filter raw water by electrochemical ion exchange when a constant voltage is applied. In addition, the ion exchange filter 310 can be regenerated to generate sterilizing water when a reverse voltage is applied.

  Therefore, as shown in FIG. 3, in order to filter the raw water to make it clean, a constant voltage is applied to the ion exchange filter 310, and the ion form foreign matter is ion exchange filter by electrochemical ion exchange. Collect at 310. Then, as shown in FIG. 4, in order to regenerate the ion exchange filter 310, that is, to remove from the ion exchange filter 310 foreign matter in the form of ions collected by the ion exchange filter 310, A voltage is applied to the ion exchange filter 310. Further, as shown in FIG. 5, in order to sterilize the raw water tank 210, or to sterilize the entire water treatment apparatus 100 including a cold and warm water part 500 described later as shown in FIG. The ion exchange filter 310 is applied.

  Thereby, the water treatment apparatus 100 can be sterilized using the sterilizing water generated by the ion exchange filter 310 without separately providing the sterilizing unit. Thus, the size and cost of production of the water treatment device is reduced and the water treatment device can be easily produced.

  As shown in FIG. 2, the ion exchange filter 310 may include a positive electrode 311, a negative electrode 312, and a bipolar ion exchange membrane 313.

  As shown in FIG. 2, the positive electrode 311 is formed, for example, in a rod shape. The negative electrode 312 can be formed in a cylindrical shape into which the rod-shaped positive electrode 311 is inserted.

  However, the shape and arrangement of the positive electrode 311 and the negative electrode 312 are not particularly limited, and any shape and arrangement can be used.

  When the anode of a power supply (not shown) is connected to the positive electrode 311 and the cathode of the power supply is connected to the negative electrode 312, a constant voltage is applied to the ion exchange filter 310. Further, when the cathode of the power supply is connected to the positive electrode 311 and the anode of the power supply is connected to the negative electrode 312, a reverse voltage is applied to the ion exchange filter 310.

  The bipolar ion exchange membrane 313 can be provided between the positive electrode 311 and the negative electrode 312. For example, as shown in FIG. 2, the bipolar ion exchange membrane 313 can be spirally wound and provided between the positive electrode 311 and the negative electrode 312. Thus, the water introduced into the ion exchange filter 310, for example, the raw water filtered by the pretreatment filter 320 can pass through the space between the spirally wound bipolar ion exchange membranes 313.

  However, the method of providing the bipolar ion exchange membrane 313 between the positive electrode 311 and the negative electrode 312 is not particularly limited, and any known method may be used.

  One side of the bipolar ion exchange membrane 313 is a cation exchange side where cations are exchanged, and the other side is an anion exchange side where anions are exchanged. Thus, when a constant voltage is applied to the ion exchange filter 310, foreign matter in the form of ions contained in water flowing in the space between the bipolar ion exchange membranes 313 is collected by the bipolar ion exchange membrane 313.

  That is, the foreign substance in the cation form contained in water moves to the cation exchange side of the bipolar ion exchange membrane 313 due to the voltage difference. Then, the foreign matter in the cation form is exchanged with hydrogen ions (H +) attached to the cation exchange side of the bipolar ion exchange membrane 313 by the electromagnetic force and collected on the cation exchange side of the bipolar ion exchange membrane 313.

  In addition, foreign matter in the form of anions contained in water moves to the anion exchange side of the bipolar ion exchange membrane 313 due to the voltage difference. Then, the foreign matter in the anion form is exchanged with the hydroxide ion (OH-) attached to the anion exchange side of the bipolar ion exchange membrane 313 by the electromagnetic force, and collected on the anion exchange side of the bipolar ion exchange membrane 313.

  Then, hydrogen ions and hydroxide ions separated from the bipolar ion exchange membrane 313 are combined to form water. Thereby, water can be filtered by the ion exchange filter 310.

  On the other hand, when a reverse voltage is applied to the ion exchange filter 310, the foreign matter in the cation form and the foreign matter in the anion form collected on the cation exchange side and the anion exchange side of the bipolar ion exchange membrane 313 by the voltage difference respectively It can be separated from the membrane 313. Thus, the cation form foreign matter and the anion form foreign matter separated from the bipolar ion exchange membrane 313 are contained in the water flowing between the bipolar ion exchange membrane 313, and as shown in FIG. It can be discharged from 310. And, the regenerated water containing foreign matter in the form of ions can be collected in the above-mentioned regeneration tank 220 as shown in FIG.

  Thus, when a reverse voltage is applied to the ion exchange filter 310, chlorine ions (Cl −) collected on the anion exchange side of the bipolar ion exchange membrane 313 can also be separated from the bipolar ion exchange membrane 313. Then, chlorine ions (Cl −) separated from the bipolar ion exchange membrane 313 are oxidized by supplying electrons to the positive electrode 311 and become chlorine gas (Cl 2) to be dissolved in water. Therefore, sterilization voltage can be generated by applying a reverse voltage to the ion exchange filter 310.

  The filtration unit 300 may further include a pre-treatment filter 320 and a post-treatment filter 330 as shown in FIG. 1 in addition to the ion exchange filter 310 described above. The pretreatment filter 320 is located in front of the ion exchange filter 310, and can filter relatively large foreign substances contained in the raw water before the raw water is filtered by the ion exchange filter 310. In addition, the post-treatment filter 330 may be positioned downstream of the ion exchange filter 310 to filter the raw water filtered by the ion exchange filter 310. For example, the post-treatment filter 330 can filter off odor particles and the like.

  However, the type, number, or position of the filters included in the filter unit 300 other than the ion exchange filter 310 are not particularly limited, and any filter may be used as long as it can filter the raw water together with the ion exchange filter 310. It is possible to use filters of any kind, number or position.

  The filtering unit 300 can include a flow path switching valve VC. The flow path switching valve VC can be connected to the raw water tank 210 via the first clean water line LF1. As shown in FIG. 1, the first water purification line LF1 is connected to the pretreatment filter 320 connected to the raw water line LRW, whereby the flow path switching valve VC is connected to the raw water via the first water purification line LF1. It can be connected to the tank 210. However, the first water purification line LF1 may be connected to the raw water tank 210 via the raw water line LRW, or may be directly connected to the raw water tank 210.

  As shown in FIG. 1, the first water purification line LF1 can be provided with a raw water supply valve VRW. As shown in FIGS. 3 to 6, when the raw water supply valve VRW is opened, the raw water stored in the raw water tank 210 can flow into the ion exchange filter 310 through the pretreatment filter 320.

  The second water purification line LF2 and the third water purification line LF3 can be connected to the flow passage switching valve VC. Then, the flow path switching valve VC can switch the flow path to the second purified water line LF2 or the third purified water line LF3.

  The second water purification line LF2 may be connected to one side of the flow path switching valve VC and the ion exchange filter 310, for example, the upper side. In addition, the third water purification line LF3 can be connected to the other side of the flow path switching valve VC and the ion exchange filter 310, for example, the lower side.

  Thus, when the flow path is switched to the second purified water line LF2 by the flow path switching valve VC, the raw water filtered by the pretreatment filter 320 is converted to the second purified water line LF2 and the second purified water line LF2 as shown in FIGS. It flows into the ion exchange filter 310 through one side of the ion exchange filter 310 and then is discharged from the ion exchange filter 310 through the other side of the ion exchange filter 310 and the third water purification line LF3.

  In addition, when the flow path is switched to the third water purification line LF3 by the flow path switching valve VC, the raw water filtered by the pretreatment filter 320 has the third water purification line LF3 and the ion as shown in FIG. 4 and FIG. It flows into the ion exchange filter 310 through the other side of the exchange filter 310 and then is discharged from the ion exchange filter 310 through one side of the ion exchange filter 310 and the second water purification line LF2.

  The third water purification line LF3 is equipped with a high flow rate sensor SF1 and can measure the flow rate of flowing water.

  As shown in FIG. 1, the first drain line LD1 can be branched from the second clean water line LF2. The first drain line LD1 can be connected to the second drain line LD2.

  The second drain line LD 2 can be branched into a raw water tank line LRT connected to the raw water tank 210 and a regeneration tank line LRG connected to the regeneration tank 220. The raw water tank line LRT can be provided with a flushing valve VF, and the regeneration tank line LRG can be provided with a drain valve VD.

  The fourth water purification line LF4 can be branched from the third water purification line LF3. The fourth water purification line LF4 can be connected to the discharge unit 400. The fourth water purification line LF4 is connected to the aftertreatment filter 330 and the fifth water purification line LF5 connected to the aftertreatment filter 330, and the discharge on / off valve 420 described later included in the discharge unit 400, for example, the discharge unit 400. It can be connected to the clean water discharge line LPD connected to the However, the fourth water purification line LF4 may be connected to the fifth water purification line LF5 via the water purification discharge line LPD, or may be directly connected to the water purification discharge line LPD.

  In such a configuration, in the state shown in FIG. 3, the raw water supply valve VRW is opened, the flow path switching valve VC switches the flow path to the second clean water line LF2, and a constant voltage is applied to the ion exchange filter 310. The flushing valve VF and the drain valve VD are closed, the discharge on-off valve 420 is opened, and the discharge switching valve 410 is connected to a later-described discharge on-off valve 420 to switch the flow path to the outside.

  Thereby, the raw water stored in the raw water tank 210 flows in the raw water line LRW by the pressurizing pump P, flows into the pretreatment filter 320, and is filtered. Raw water filtered by the pretreatment filter 320 flows through the first water purification line LF1, the flow path switching valve VC, and the second water purification line LF2, flows into the ion exchange filter 310, and is filtered. The raw water filtered by the ion exchange filter 310 flows through the third water purification line LF3 and the fourth water purification line LF4, flows into the post-treatment filter 330, and is filtered. Then, the raw water filtered by the post-treatment filter 330, that is, the purified water flows through the fifth purified water line LF5 and the purified water discharge line LPD, and is discharged to the outside through the discharge on-off valve 420 and the discharge switching valve 410, Supplied to the user.

  In the state shown in FIG. 4, the raw water supply valve VRW is opened, the flow path switching valve VC switches the flow path to the third water purification line LF3, a reverse voltage is applied to the ion exchange filter 310, and the flushing valve VF is closed. The drain valve VD is opened and the discharge on-off valve 420 is closed.

  Thereby, the raw water stored in the raw water tank 210 flows in the raw water line LRW by the pressurizing pump P, flows into the pretreatment filter 320, and is filtered. Raw water filtered by the pretreatment filter 320 flows through the first water purification line LF1, the flow path switching valve VC, and the third water purification line LF3 and flows into the ion exchange filter 310 to regenerate the ion exchange filter 310. . The regenerated water in which the ion exchange filter 310 is regenerated flows through the second purified water line LF2, the first drain line LD1, the second drain line LD2, and the regeneration tank line LRG, and is collected in the regeneration tank 220.

  Such regeneration of the ion exchange filter 310 can be performed in a state where most of the raw water stored in the raw water tank 210 is filtered and only a predetermined amount of raw water remains. Thus, after regeneration of the ion exchange filter 310, the raw water tank 210 can be emptied.

  In the state shown in FIG. 5, the raw water supply valve VRW is opened, the flow path switching valve VC switches the flow path to the third water purification line LF3, a reverse voltage is applied to the ion exchange filter 310, and the flushing valve VF is opened. Then, the drain valve VD is closed and the discharge on-off valve 420 is closed.

  Thereby, the raw water stored in the raw water tank 210 flows in the raw water line LRW by the pressurizing pump P, flows into the pretreatment filter 320, and is filtered. Raw water filtered by the pretreatment filter 320 flows through the first water purification line LF1, the flow path switching valve VC, and the third water purification line LF3 and flows into the ion exchange filter 310 for producing sterilizing water. The sterilizing water generated by the ion exchange filter 310 flows into the raw water tank 210 by flowing through the second purified water line LF2, the first drain line LD1, the second drain line LD2, and the raw water tank line LRT. The tank 210 will be sterilized.

  The sterilizing water introduced into the raw water tank 210 continues to circulate through the pretreatment filter 320 and the ion exchange filter 310 to sterilize the raw water tank 210.

  Such sterilization of the raw water tank 210 can be performed before the raw water is filtered to produce purified water as shown in FIG. 3 in a state where the raw water tank 210 is full of raw water. However, the raw water tank 210 can also be sterilized while producing purified water.

  On the other hand, the first drain line LD1 is provided with a drain on-off valve VDC, which can open and close the first drain line LD1.

  The discharge unit 400 can discharge the raw water filtered by the filter unit 300, that is, the purified water to the outside and supply it to the user. To that end, the discharge unit 400 can include a discharge switching valve 410 and a discharge on-off valve 420. The discharge switching valve 410 can be connected to the discharge on-off valve 420. And the discharge on-off valve 420 can be connected to the fifth clean water line LF5 via the clean water discharge line LPD.

  Therefore, as shown in FIG. 3, when the discharge switching valve 410 switches the flow path to the outside and the discharge on-off valve 420 is opened, the pretreatment filter 320, the ion exchange filter 310, and the posttreatment filter 330. The filtered raw water, that is, the purified water flows in the fifth water purification line LF5, is discharged to the outside through the discharge on-off valve 420 and the discharge switching valve 410, and is supplied to the user.

  Meanwhile, the water treatment apparatus 100 according to an embodiment of the present invention may further include a hot and cold water unit 500.

  The cold and warm water line LCH can be connected to the fifth water purification line LF5. The cold / hot water line LCH can be branched into a cold water line LC connected to the cold water tank 510 and a hot water line LH connected to the instantaneous water heater 520. Thereby, the cold and warm water part 500 can be connected to the filtration part 300.

  The cold water tank 510 can be connected to a tank drain line LDT including a tank drain valve VDT. Thus, when the tank drain valve VDT is opened, the cold water stored in the cold water tank 510 can be drained to the outside.

  In addition, the cold water tank 510 and the discharge switching valve 410 can be connected to a tank vent line LVT including a tank vent valve VVT.

  The hot water line LH can include a low flow sensor SF2, a temperature sensor ST, and a flow control valve VFC. Thus, the flow rate and temperature of the purified water flowing into the instantaneous water heater 520 can be measured, and the flow rate of the purified water flowing into the instantaneous water heater 520 can be adjusted.

  The hot water discharge line LHD can also include a temperature sensor ST. Thereby, the temperature of the hot water flowing in the hot water discharge line LHD can be measured.
