FIGS. 3 to 6 are views showing a usage state of the water treatment apparatus according to the embodiment of the present invention.

  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. For this purpose, the supply unit 200 may include a raw water tank 210 as shown in FIG. Raw water can be stored in the raw water tank 210.

  For example, the user can take an empty raw water tank 210 to a raw water supply source (not shown) such as a tap and store raw water from the raw water supply 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, or any known one that can supply raw water.

  The raw water tank 210 can be connected to the filtration unit 300 through the raw water line LRW. For example, the raw water tank 210 can be connected to the pretreatment filter 320 (described later) included in the filtration unit 300 via the raw water line LRW, and can be connected to the filtration unit 300.

  And as FIG. 1 showed, the raw | natural water line LRW can contain the pressurization pump P and the pressure reduction 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 pressurizing pump P and the pressure reducing valve VR.

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

  The supply unit 200 can include a regeneration tank 220 in addition to the raw water tank 210 described above. As shown in FIG. 4, regenerated water that has passed through the ion exchange filter 310 can be collected in the regeneration tank 220 when the ion exchange filter 310 included in the filtration unit 300 is regenerated.

  When a predetermined amount of recycled 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 recycled water collected in the regeneration tank 220.

  The filtration unit 300 can filter the raw water supplied from the supply unit 200. For this purpose, the filtering unit 300 may 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. The ion exchange filter 310 can be regenerated to generate sterilized water when a reverse voltage is applied.

  Therefore, as shown in FIG. 3, in order to filter raw water into purified water, a constant voltage is applied to the ion exchange filter 310, and ion-type foreign substances are removed by ion exchange electrochemically. Collect at 310. As shown in FIG. 4, in order to regenerate the ion exchange filter 310, that is, to remove the ionic form of foreign matter collected by the ion exchange filter 310, the reverse A voltage is applied to the ion exchange filter 310. Further, in order to sterilize the raw water tank 210 as shown in FIG. 5 or to sterilize the entire water treatment apparatus 100 including the cold / hot water section 500 described later as shown in FIG. Applied to the ion exchange filter 310.

  Thereby, even if it does not provide a sterilization part separately, the water treatment apparatus 100 can be sterilized using the sterilization water produced | generated with the ion exchange filter 310. FIG. Therefore, the size and production cost of the water treatment device are 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 in a rod shape, for example. 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 form of the positive electrode 311 and the negative electrode 312 are not particularly limited, and any shape and arrangement form can be adopted.

  When the anode of the power source (not shown) is connected to the positive electrode 311 and the cathode of the power source is connected to the negative electrode 312, a constant voltage is applied to the ion exchange filter 310. When the cathode of the power source is connected to the positive electrode 311 and the anode of the power source 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 may be provided between the positive electrode 311 and the negative electrode 312 by being spirally wound. Thereby, the water that has flowed into the ion exchange filter 310, for example, the raw water filtered by the pretreatment filter 320, can pass through the space between the bipolar ion exchange membranes 313 wound spirally.

  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. As a result, when a constant voltage is applied to the ion exchange filter 310, foreign substances in the form of ions contained in water flowing in the space between the bipolar ion exchange membranes 313 are collected in the bipolar ion exchange membrane 313.

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

  Moreover, the anion-form foreign material contained in the water moves to the anion exchange side of the bipolar ion exchange membrane 313 due to a voltage difference. The foreign substances in anion form are exchanged with hydroxide ions (OH−) attached to the anion exchange side of the bipolar ion exchange membrane 313 by electromagnetic force, and are 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 cation-type foreign matter and the anion-type foreign matter collected on the cation exchange side and the anion exchange side of the bipolar ion exchange membrane 313 by the voltage difference are bipolar ion exchanged. It can be separated from the membrane 313. As described above, the cation-type foreign matter and the anion-type foreign matter separated from the bipolar ion exchange membrane 313 are contained in the water flowing between the bipolar ion exchange membranes 313, and as shown in FIG. 310 can be discharged. Then, the reclaimed water containing foreign substances in the form of ions can be collected in the above-described 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. 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) and dissolved in water. Therefore, sterilized water can be generated by applying a reverse voltage to the ion exchange filter 310.

  In addition to the ion exchange filter 310 described above, the filtration unit 300 may further include a pretreatment filter 320 and a posttreatment filter 330 as illustrated in FIG. The pretreatment filter 320 is located in front of the ion exchange filter 310 and can filter relatively large foreign matters contained in the raw water before the raw water is filtered by the ion exchange filter 310. Moreover, the post-processing filter 330 is located in the subsequent stage of the ion exchange filter 310, and can filter the raw water filtered by the ion exchange filter 310. For example, the post-processing filter 330 can filter odor particles and the like.

  However, the type and number of filters included in the filtration unit 300 in addition to the ion exchange filter 310 or the position where the filters are arranged are not particularly limited, and any filter can be used as long as raw water can be filtered together with the ion exchange filter 310. Filters of various types, numbers, or positions can be used.

  The filtration unit 300 may 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 water purification 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, so that 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 may include 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.

  A second water purification line LF2 and a third water purification line LF3 can be connected to the flow path switching valve VC. And the flow-path switching valve VC can switch a flow path to the 2nd water purification line LF2 or the 3rd water purification line LF3.

  The second water purification line LF2 can be connected to one side, for example, the upper part, of the flow path switching valve VC and the ion exchange filter 310. 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 part.

  Thus, when the flow path is switched to the second water purification line LF2 by the flow path switching valve VC, the raw water filtered by the pretreatment filter 320 is connected to the second water purification line LF2 as shown in FIGS. It flows into the ion exchange filter 310 through one side of the ion exchange filter 310, and is then 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 is ionized with the third water purification line LF3 as shown in FIGS. It flows into the ion exchange filter 310 through the other side of the exchange filter 310, and is then 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 provided 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 water purification line LF2. The first drain line LD1 can be connected to the second drain line LD2.

  The second drain line LD2 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 4th water purification line LF4 can be branched from the 3rd water purification line LF3. The 4th water purification line LF4 can be connected with the discharge part 400. FIG. The fourth water purification line LF4 is connected to the post-treatment filter 330 described above and the fifth water purification line LF5 connected to the post-treatment filter 330. It can be connected with the purified water discharge line LPD connected to. 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 water purification 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 opening / closing valve 420 is opened, and the discharge switching valve 410 is connected to a discharge opening / closing valve 420 described later to switch the flow path to the outside.

  Thereby, the raw water stored in the raw water tank 210 flows through the raw water line LRW by the pressurizing pump P, flows into the pretreatment filter 320, and is filtered. The 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. The raw water filtered by the post-processing filter 330, that is, 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 opening / closing 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. Then, the drain valve VD is opened, and the discharge opening / closing valve 420 is closed.

  Thereby, the raw water stored in the raw water tank 210 flows through the raw water line LRW by the pressurizing pump P, flows into the pretreatment filter 320, and is filtered. The 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, flows into the ion exchange filter 310, and regenerates the ion exchange filter 310. . The reclaimed water regenerated from the ion exchange filter 310 flows through the second water purification 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. Therefore, the raw water tank 210 can be emptied after the regeneration of the ion exchange filter 310.

  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. Accordingly, the drain valve VD is closed, and the discharge opening / closing valve 420 is closed.

  Thereby, the raw water stored in the raw water tank 210 flows through the raw water line LRW by the pressurizing pump P, flows into the pretreatment filter 320, and is filtered. The 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 that generates sterilized water. The sterilized water generated by the ion exchange filter 310 flows through the second water purification line LF2, the first drain line LD1, the second drain line LD2, and the raw water tank line LRT and flows into the raw water tank 210, where the raw water The tank 210 will be sterilized.

  The sterilizing water flowing 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.

  The sterilization of the raw water tank 210 can be performed before the raw water is filtered to generate purified water as shown in FIG. 3 while the raw water tank 210 is filled with the raw water. However, the raw water tank 210 can be sterilized while generating purified water.

  On the other hand, the first drain line LD1 is provided with a drain opening / closing 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, purified water, to the outside and supply it to the user. Therefore, the discharge unit 400 may include a discharge switching valve 410 and a discharge opening / closing valve 420. The discharge switching valve 410 can be connected to the discharge opening / closing valve 420. And the discharge on-off valve 420 can be connected to the 5th water purification line LF5 via the water purification 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, purified water flows through the fifth purified water line LF5, is discharged to the outside through the discharge opening / closing 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 cold / hot water unit 500. The cold / hot water unit 500 may be connected to the filtration unit 300 and the discharge unit 400. And the cold / hot water part 500 can cool or heat the raw water filtered by the filtration part 300, ie, purified water.

  Further, 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. Accordingly, when the purified water flows into the cold water tank 510, when the tank vent valve VVT is opened and the discharge switching valve 410 switches the flow path to the outside, the air in the cold water tank 510 flows through the tank vent valve VVT. Discharged to the outside.

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

  Therefore, the third drain line LD3 connected to the second drain line LD2 can be connected to the discharge switching valve 410.

  Then, the raw water supply valve VRW is opened, and the flow path switching valve VC switches the flow path to the second water purification line LF 2 so that a reverse voltage is applied to the ion exchange filter 310. Further, the flushing valve VF is opened, the drain valve VD is closed, the discharge opening / closing valve 420 is opened, and the flow path is switched to the third drain line LD3 by the discharge switching valve 410.
