Since the first upward guide provided in the member is disposed through the center of the anti-scale filter member, purified water is not mixed with concentrated water, so that the operation stability of the water purifier can be secured. First to third partition walls are provided to form independent passages in which water does not mix, so that tubes through which raw water, purified water, regenerated water, and concentrated water flow are concentrated on the upper part of the composite filter to improve the layout design freedom of other parts.

Various water treatment devices, such as water purifiers, that generate purified water by filtering obtained raw water are currently being disclosed. Among the methods applied to these water treatment devices, methods that have recently been in the limelight are electro deionization methods such as EDI (Electro Deionization), CEDI (Continuous Electro Deionization), and CDI (Capacitive Deionization). Among them, the CDI method refers to a method of removing ions (contaminants) by using a principle in which ions are adsorbed and desorbed from the surface of an electrode by electric power. That is, when brine water containing ions is passed between the electrodes (anode and cathode) while voltage is applied to the electrodes, anions move to the anode and cations move to the cathode, and adsorption occurs. This adsorption can remove ions in the brine. On the other hand, when the electrode continuously adsorbs ions, the electrode reaches a saturation state where it can no longer adsorb ions. When this state is reached, the electrode is regenerated by desorbing the ions adsorbed on the electrode. This can be achieved by not applying a voltage to the electrode, or by applying a voltage opposite to that for adsorption.

In the water purifier disclosed in US Patent Publication No. 2013-0277222 of COWAY CO., LTD., a conventional electric deionization type filter is disclosed. That is, a first electrochemical filter and a second electrochemical filter are provided so that when a regeneration process is performed in one electrochemical filter, continuous filtration of raw water is possible through the other electrochemical filter. When configured together, since a plurality of electrochemical filters are required, there is a problem in that the water purifier cannot be manufactured in a compact size due to the increase in the space occupied by the electrochemical filters. In addition, due to the scale generated in the process of regenerating the electrochemical filter, there is a problem of reducing the performance and shortening the life of the electrochemical filter.

The conventional water purifier disclosed in Korea Patent Publication No. 2010-0106857 of Woongjin Coway Co., Ltd. has a separate hard material removing unit containing a material that removes hard materials such as calcium ions and magnesium ions contained in inflow water, so that such hardness Scale is prevented from being formed in the reverse osmosis membrane filter by configuring the water passing through the material removal unit to be filtered while passing through the reverse osmosis membrane filter. However, when the hardness material removal unit is provided separately, there is a problem in that the water purifier cannot be manufactured in a compact size due to the increase in the volume of the entire filter.

Korean Patent Publication No. 2013-0096563 of Picogram Co., Ltd. discloses a ceramic filter for a water purifier having a function of preventing scale formation, but when such a ceramic filter is applied to a water purifier, the volume of the entire filter increases due to the space occupied by the ceramic filter. As a result, there is a problem in that the water purifier cannot be manufactured in a small size.

9 is a block diagram showing an entire water piping diagram of a water purifier equipped with a composite filter according to an embodiment of the present invention.

As shown in FIG. 9, in the water purifier equipped with a complex filter according to an embodiment of the present invention, the flow of raw water (W1), purified water (C), regenerated water (W2), and concentrated water (W3) is controlled. The valve unit 300 and a control unit 400 controlling the operation of the valve unit 300 may be further included. The valve unit 300 includes a first valve 310 for regulating the flow of raw water (W1), a second valve 320 for regulating the flow of purified water (C), and regulating the flow of regenerated water (W2). A third valve 330 and a fourth valve 340 controlling the flow of concentrated water W3 may be included. That is, it is possible to control the flow of raw water (W1), purified water (C), regenerated water (W2), and concentrated water (W3) by controlling the valve unit 300 through the control unit 400, and preventing these fluids from flowing backward. By effectively preventing it, it is possible to secure product reliability.

At this time, in the water purifier equipped with a composite filter according to an embodiment of the present invention, the control unit 400, when extracting purified water (C), the valve unit allows the intake of raw water (W1) and the discharge of purified water (C). 300 is controlled, and when washing the external water filter member 50, the valve unit 300 can be controlled so that regeneration water W2 can be obtained and concentrated water W3 can be discharged. For example, the control unit 400 opens the first valve 310 and the second valve 320 when extracting purified water C, and opens the third valve 330 and 330 when cleaning the external water filter member 50. The fourth valve 340 may be controlled to open. That is, by controlling the valve unit 300 through the control unit 400, stable extraction of purified water C and washing of the external purified water filter member 50 are possible, thereby improving user satisfaction.

Meanwhile, in the water purifier equipped with a complex filter according to an embodiment of the present invention, the valve unit 300 is a washing water valve ( 350), and the control unit 400 controls the condensed water W3 and the washing water W5 to be simultaneously supplied to the external water filter member 50 for a predetermined time when washing of the external water filter member 50 starts. And, after a certain time has elapsed, the supply of the concentrated water (W3) may be stopped, and only the washing water (W5) may be supplied. For example, the washing water (W5) and the concentrated water (W3) are supplied only for a certain time (about 2 minutes) when the washing starts among the total time (assuming about 10 minutes) for washing the external water filter member 50. It is supplied at the same time, and only the washing water (W5) is supplied after a certain period of time. This is because a large amount of calcium ions, magnesium ions or foreign substances are separated at the initial stage of washing the external water filter member 50, and when these separated ions or foreign substances combine with the washing water W5, scale may be formed, but the concentrated water W3 If is supplied together, the separated ions or foreign substances are discharged without being combined with the washing water (W5), so the formation of scale can be minimized. If the separated ions or foreign substances are discharged to the outside at the beginning of the cleaning process, scale is not formed even if only the washing water W5 is supplied in the subsequent cleaning process. In addition, if the concentrated water (W3) is continuously supplied throughout the washing time, the flow of the regeneration water (W2) and the concentrated water (W3) is quickly formed, so there is a problem of channeling occurring inside the anti-scale filter member (70). However, as described above, if the valve unit 300 is controlled so that the concentrated water W3 is supplied only for a certain period of time when washing starts, the channeling problem can be prevented. The concentration of the concentrated water (W3) is approximately 30 to 50 ppm, but is supplied to the external water filter member 50 in a state in which the concentration is reduced to about 1 to 2 ppm as it is diluted by the washing water (W5). At this time, the washing water W5 may be supplied using raw water W1, and the received washing water W5 passes through the pressure reducing valve 11 and moves in a reduced pressure state. That is, the washing water W5 and the concentrated water W3 are controlled to be supplied together only at the beginning of washing the external water filter member 50, and only the washing water W5 is supplied after the separated ions or foreign substances are discharged to the outside. By doing so, it is possible to efficiently use the concentrated water (W3), and by controlling the supply of the concentrated water (W3) only during a certain period of time when the washing is started, it is possible to prevent a channeling problem from occurring inside the anti-scale filter member (70), thereby making a water purifier. operation stability can be secured.

In addition, in the water purifier equipped with a composite filter according to an embodiment of the present invention, the control unit 400, when a replacement signal for the composite filter is input, regenerates water into the first space Z1 and the second space Z2. The valve unit 300 may be controlled to fill W2, but the concentrated water W3 may be discharged after a certain period of time has elapsed. When the composite filter is replaced, since the inside of the anti-scale filter member 70 is empty, regeneration water is supplied to the first space Z1 and the second space Z2 to generate concentrated water W3, and the supplied regeneration water W2 ) controls the valve unit 300 not to use the concentrated water W3 for a certain period of time (about 3 hours) when the concentrated water W3 is generated while the anti-scale material is dissolved. That is, when a replacement signal for the complex filter is input to the control unit 400, the regeneration water W2 is supplied so that the concentrated water W3 is generated, and the concentrated water W3 is not discharged for a certain period of time when the concentrated water W3 is generated. It is possible to secure the concentrated water (W3) at an appropriate concentration by controlling the water purifier to ensure operation stability of the water purifier through effective cleaning of the external water filter member (50).

As described above, the water purifier equipped with the composite filter according to the present invention is capable of not only inflow of raw water (W1) and outflow of purified water (C), but also inflow of regenerated water (W2) and discharge of concentrated water (W3), so that the internal water filter member ( 60) and the anti-scale filter member 70 are integrated to form a composite filter, so that the water purifier can be miniaturized and replaced easily, thereby improving user convenience, and the anti-scale filter member 70 on top of the internal water filter member 60 In the stacked arrangement, the first upward guide 211 provided on the first upper cap member 210 is anti-scale so that purified water C generated from the internal water filter member 60 disposed below is discharged to the outside. By being disposed through the center of the filter member 70, the purified water C is not mixed with the concentrated water W3, so that the operation stability of the water purifier can be secured, and the raw water ( W1), purified water (C), regenerated water (W2), and concentrated water (W3) are provided with first to third partition walls 111, 112, and 113 to form an independent flow path where the raw water (W1) and purified water (W3) are not mixed. (C), the tubes through which the regeneration water (W2) and the concentrated water (W3) flow are concentrated on the upper part of the complex filter, so that the layout design freedom of other parts is improved.

Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented herein, and those skilled in the art who understand the spirit of the present invention may add elements within the scope of the same spirit. However, other embodiments can be easily proposed by means of changes, deletions, additions, etc., but these will also fall within the scope of the present invention.
