The present invention relates to an ion water purifier, and more particularly, to an ion water purifier that generates a large amount of alkaline ionized water at the same time and filters the precipitates generated in the alkaline ionized water without changing the water temperature.

In general, a cold ion water purifier passes through a filter unit to separate purified water into acidic water and alkaline water in an electrolytic cell, and then provides acidic water, cold alkaline ionized water or warm alkaline ionized water.

As such a cold and hot water ionizer, it is proposed in the publication of Korean Utility Model Registration No. 20-0327037.

As shown in FIG. 1, the conventional cold and hot water purifier 100 includes a filter unit 110 for filtering and purifying tap water and a reservoir for storing purified water from the filter unit 110, as shown in FIG. 1. 120, an electrolytic cell 130 for electrically decomposing purified water introduced from the reservoir 120 to generate acidic water and alkaline ionized water.

In addition, the acid water tank 140 for storing the acidic water generated from the electrolytic cell 130, the heating means 153 for heating the alkali ion water generated from the electrolytic cell 130 and the hot water tank for storing the heated alkaline ionized water Cold water tank consisting of a hot water tank 150 made of 155, a cooling means 163 for cooling the alkali ion water generated from the electrolytic cell 130 and a cold water tank 165 for storing the cooled alkaline ionized water ( 160).

In addition, the drain manifold 190 is connected to the water reservoir 120, the acid water tank 140, the hot water tank 150, the cold water tank 160 and the room temperature water pipes 170, 180 to perform the automatic drain operation. Consists of including.

However, the electrolytic cell 130 mounted on the cold ion water purifier 100 serves to reduce the flow rate in view of the flow path and the flow rate between the filter unit 110 and the water extraction cock. In addition, since the purified water introduced into the electrolytic cell 130 is discharged with alkaline ionized water due to the characteristics of the electrolytic cell 130, the extraction efficiency is always less than 1. Since the efficiency is about 40% to 60%, the smooth outflow of alkaline water varies depending on the raw water pressure, but generally there is less problem than the amount of outflow from the general water purifier.

In addition, alkaline ionized water of the ionizer 100 is a functional water containing abundant minerals such as Ca +, K +, Mg +. Therefore, the alkaline ionized water of the ion water purifier 100 has a very high reactivity of the minerals, so that the alkaline ionized water contains carbon dioxide or the like, or when the water temperature rises or the partial pressure of carbon dioxide in the air decreases so that the dissolved amount of carbon dioxide decreases. Sediments such as calcium carbonate, which are insoluble in water, are deposited. These precipitates are reactants produced by the reaction upon storage in the tank after electrolysis. However, since the ion water purifier 100 also has functions of electrolysis and purification, it is not preferable that such a precipitate is discharged.

The present invention has been made to solve the above-described problems, and an object thereof is to provide an ion water purifier that simultaneously generates a large amount of alkaline ionized water and filters the precipitates generated in the alkaline ionized water without changing the water temperature.

The ion purifier of the present invention for achieving the above object comprises a pre-treatment filter unit for filtering and purifying the raw water, two or more electrolyzers to produce acidic and alkaline ionized water by electrolysis of the filtered purified water, the electrolytic cell Are paralleled to each other. In addition, the alkaline ionized water is cooled and stored, the inlet and the outlet is formed of a cold water tank, and the sediment filter unit disposed inside the cold water tank, and the coupling means for coupling the sediment filter unit to the cold water tank is made, The sediment filter part comprises a housing, a filter material disposed inside the housing, an outlet part formed on the lower surface of the housing, and a side inlet part formed on the side surface of the housing.

According to this configuration, the ionizer can provide a large amount of alkaline ionized water at the same time. In addition, the ion water purifier may filter the precipitate which may be generated while the alkaline ionized water is stored in the cold water tank without raising the water temperature.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, with respect to the same configuration as the prior art of the configuration of the present invention to be described below will be referred to the above-described prior art, and a detailed description thereof will be omitted.

2 is a schematic view showing an ion water purifier according to a preferred embodiment of the present invention.

As shown in FIG. 2, the ion water purifier of the present embodiment is composed of a pretreatment filter unit 11 for filtration and purification of raw water, and an electrolytic cell 13 for generating acidic water and alkaline ionized water by electrolyzing the filtered purified water. .

The pretreatment filter unit 11 is composed of a plurality of filters for filtering and purifying raw water such as water and ground water.

The electrolyzer 13 electrolyzes the purified water filtered by the pretreatment filter unit 11 to generate acidic water and alkaline ionized water.

In more detail, the electrolytic cell 13 is divided into an anode chamber and a cathode chamber by a partition wall through which only ions having electrical properties can pass, and when voltage is applied thereto, ionized water is generated as water is electrolyzed.

That is, when a voltage is applied to each electrode of the positive and negative electrode chambers, hydroxyl ions are reduced and oxygen gas is generated in the positive electrode chamber, so that hydroxyl ions in water are consumed, and anions such as chlorine, phosphorus, and sulfur other than the hydroxide ions are By forming an acid, the water in the anode chamber becomes acidic.

In the cathode chamber, hydrogen ions are reduced and hydrogen gas is generated, so hydrogen ions in water are consumed. At this time, cations such as sodium, magnesium, and calcium other than hydrogen ions form hydrogen ion pairs, and the solution in the cathode chamber becomes alkaline. . Alkaline ionized water thus produced is used for beverages, and acidic ionized water is used for skin care or disinfectant water.

Alkaline ionized water is generated through such a process, and thus, the amount of generation generated during the predetermined time is not large, so that smooth outflow is not achieved. Therefore, it is preferable that at least two electrolytic cells 13 are provided. The number of electrolyzers 13 may vary depending on the capacity of the alkaline ionized water to be obtained. Here, it is preferable that the plurality of electrolyzers 13 be connected in parallel so that the purified water can be processed in parallel.

In this embodiment, the first electrolytic bath 131 and the second electrolytic bath 132 are provided, and the two electrolytic baths 13 are connected in parallel. The purified water filtered by the pretreatment filter unit 11 flows into the electrolytic cell 13 through the flow path. At this time, the purified water that came through one flow path is branched into two branches and flows into each electrolytic cell 13. The purified water introduced into both electrolyzers 13 is electrolyzed in both electrolyzers 13 at the same time. Therefore, it is possible to simultaneously deliver a double integer than when having one electrolytic cell (13). In this way, the alkaline ionized water electrolyzed in each electrolytic cell 13 is collected in one flow path and then discharged.

A water extraction unit 70 through which alkaline ionized water may be extracted may be provided.

On the other hand, according to another embodiment of the present invention, as shown in Figure 3, the pre-treatment filter unit 11 for filtering and purifying the raw water, and the electrolytic cell for generating acidic water and alkaline ionized water by electrolyzing the filtered purified water ( 13), a cold water tank 16 for cooling and storing the alkaline ionized water, and a precipitate filter 20 for filtering the precipitate produced in the alkaline cold water.

The electrolyzer 13 is provided with two electrolyzers 13 of the first electrolyzer 131 and the second electrolyzer 132, and the two electrolyzers 13 are connected in parallel. The purified water filtered by the pretreatment sediment filter unit 11 is introduced into the electrolytic cell 13 through the flow path. At this time, the purified water that came through one flow path is branched into two branches and flows into each electrolytic cell 13. The purified water introduced into both electrolyzers 13 is electrolyzed in both electrolyzers 13 at the same time. Therefore, it is possible to simultaneously deliver a double integer than when having one electrolytic cell (13). Thus, the alkaline ionized water delivered from each electrolytic cell 13 is collected in one flow path and then immediately discharged into alkaline room temperature water without passing through the cold water tank 16 or the hot water tank 15, or the cold water tank 16 or the hot water tank 15. Can be cooled or warmed and discharged.

The cold water tank 16 cools and stores the alkaline ionized water generated from the electrolytic cell 13.

Even when purified water is stored in the cold water tank 16 and discharged, contaminants such as scale or bacteria may be generated in the stored purified water. In addition, when the purified water is alkaline ionized water, since many highly reactive mineral components are contained therein, precipitates such as calcium carbonate may be further formed.

Therefore, the ion water purifier is preferably provided with a sediment filter unit 20 for filtering the sediment in order to prevent the sediment or contaminants are mixed out during the extraction.

Here, when the sediment filter unit 20 is installed independently of the cold water tank 16, the temperature is higher than the alkali cold water temperature of the cold water tank 16 so that the cold water in the cold water tank 16 to the sediment filter unit 20 As it passes, the water temperature rises. Therefore, the sediment filter unit 20 is disposed inside the cold water tank 16, so that the temperature of the sediment filter unit 20 itself is the same as the temperature of the cold water tank 16 to prevent the temperature of the cold water from rising. It is preferable.

The precipitate filter unit 20 may be mounted inside the cold water tank 16 through a coupling means as shown in FIG. 4. The cold water tank 16 has an inlet 161 through which water is introduced from the outside, and an outlet 163 for extracting alkaline ionized water stored on a lower surface thereof.

The sediment filter part 20 includes a housing 21, a filter material 24 disposed inside the housing 21, an outlet part formed on a lower surface of the housing 21, and a side inlet formed on a side surface of the housing 21. It comprises a portion 22.

The housing 21 has a cylindrical shape and surrounds the filter medium 24 for filtering alkaline ionized water introduced into the housing 21.

The outlet portion is formed on the lower surface of the housing 21 so that the introduced alkaline ionized water passes through the filter medium 24 so that it can be easily discharged by gravity.

Coupling means is composed of an outlet pipe 54 is coupled to the outlet pipe 23 and the outlet pipe 23, the outlet pipe 23 is formed in the outlet. By the above configuration, the precipitate filter unit 20 can be easily coupled to the cold water tank (16).

The outlet pipe 23 may be pressed into the outlet 54 to mount the sediment filter unit 20 to the cold water tank 16, but the sediment filter unit 20 needs to be replaced frequently. It is preferable to fasten the screw to facilitate its detachment.

Here, the thread 25 is formed on the side of the outlet pipe 23 and the outlet 163, or an insert having a female thread is inserted into the outlet 163, and a male thread is formed in the outlet pipe 23. The outlet pipe 23 and the outlet 163 may be screwed.

On the other hand, in order to allow all the alkaline ionized water in the cold water tank 16 to pass through the precipitate filter unit 20, there should be no leakage. Therefore, when the outlet 163 and the outlet pipe 23 are coupled, it is preferable to prevent leakage between the outlet 163 and the outlet pipe 23 through an O-ring 165 therebetween.

On the side of the housing 21, a plurality of hole-shaped side inlet portions 22 are formed in all directions. By the structure as described above, the precipitate filter unit 20 can be filtered by simultaneously introducing a large amount of alkaline ionized water in the cold water tank 16 from all sides through the side inlet 22. In addition, the sediment filter unit 20 is lower than the inlet portion of the alkaline ionized water is introduced when the inlet is formed on the upper surface, because the water pressure acting on the side inlet 22 is greater in the cold water tank 16 Alkaline ionized water can be easily introduced.

On the other hand, water tends to collect in the cold water tank after cooling. Thus, like the precipitate filter unit 200 shown in FIG. 5, the side inlet unit 220 is formed at the lower side of the housing 210 so that only sufficiently cooled cold water is filtered through the filter medium 240 and then discharged. You can do that.

In addition, cold water is ideally cooled to 4 degrees. This 4 degrees Celsius water has the highest density and is deposited on the lowest surface when stored in the cold water tank 16. Accordingly, the lower surface of the housing 210, the lower surface inlet 260 that can introduce the alkaline ionized water in the cold water tank 16 is formed, the alkaline cold water of the lowest surface of the cold water tank 16 is sufficiently inflowed after It is desirable to provide filtering.

On the other hand, when the lower surface inlet portion 260 through which the alkaline ionized water may be introduced into the lower surface of the housing 210 as described above, the precipitate filter unit 200 is the lower surface and the cold water tank 16 of the housing 210. It is preferable that a gap 164 is formed between the lower surfaces of the " Therefore, when the thread 250 is formed in the outlet pipe 230, the thread 250 is formed after being spaced apart from the lower surface of the housing 210, thereby lowering the lower surface of the housing 210 and the lower surface of the cold water tank 16. It is preferable to fasten the gap 164 to be formed therebetween.

In addition, when the purified water is alkalized and then filtered by the precipitate filter unit 20, the filter media 24 and 240 of the precipitate filter unit 20 is preferably a hollow fiber membrane filter. The hollow fiber membrane filter is a fibrous filtration membrane, and the surface pores are 0.01 to 0.04 micrometers more than 100 billion holes have ultra-precision filtration performance. Therefore, the hollow fiber membrane filter has a merit to filter bacteria and viruses and fine impurities, and to make the mineral component living water. Therefore, the alkaline purified water can maintain the alkalinity even after being filtered by the precipitate filter unit 20.

 On the other hand, since the alkali ion water stored in the cold water tank 16 passes through the sediment filter part 20, the water pressure is low, so that the filtering is not performed well. Therefore, by providing the cold water tank 16 and the pump 30, it is preferable to ensure a good flow rate to ensure a good flow rate. In addition, the pump 30 allows the alkaline ionized water of the electrolytic cell 13 to flow into the cold water tank 16 to maintain the water level.

In addition, a stage detection switch (LPS) 40 may be provided to detect the stage to prevent idling of the pump 30 to prevent damage to the pump 30.

Furthermore, the ion water purifier may be provided with a hot water tank 15 for heating and storing the alkaline ionized water generated from the electrolytic cell 13 to provide alkaline hot water.

Although not shown in the drawing, the hot water tank 15 may remove the sediment or contaminants that may occur inside the hot water tank 15 without heat loss by disposing the sediment filter unit 20 therein.

In addition, a water extraction unit 70 capable of withdrawing alkaline ionized water is provided.

Solenoid valves for controlling the flow of purified water may be provided on each flow path in order to selectively and efficiently withdraw water.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art can be carried out by variously modifying or modifying the present invention without departing from the spirit and scope of the invention described in the claims below. have.

According to the ion purifier of the present invention as described above, there are the following effects.

Can be.

Second, the precipitate filter unit is disposed inside the cold water tank, thereby filtering the precipitate and the scale and bacteria due to the mineral component that can be generated while the alkaline ionized water is stored in the cold water tank to provide a clean alkaline ionized water. In addition, since the temperature of the precipitate filter unit and the cold water storage temperature are the same, the cold water of the cold water tank may be filtered by the precipitate filter unit while maintaining the water temperature.

Third, by forming the side inlet on the side of the sediment filter unit housing, the hydraulic pressure acts more than when formed on the upper surface, it is possible to easily introduce the alkaline ionized water in the cold water tank. In addition, by forming a large number of the side inlet portions in all directions, it is possible to filter by flowing a large amount of alkaline ionized water. In addition, since there is no need for a separate inlet pipe, its structure is simple and molding is also easy.

Fourth, by forming the side inlet portion under the filter housing, it is possible to filter and provide only the sufficiently cooled cold water collected in the cold water tank.

Fifth, by forming the lower surface inlet portion on the lower surface of the housing, the alkaline ionized water cooled to the ideal temperature located on the bottom surface of the cold water tank can be introduced and filtered. In addition, by filtering the precipitate precipitated on the lower surface like alkaline ionized water, it is possible to keep the inside of the cold water tank clean at all times.

Sixth, since the outlet portion is an outlet tube, the sediment filter portion can be easily mounted in the cold water tank because it is easily coupled to the outlet. In addition, by screwing it, the sediment filter part can be firmly fixed to the cold water tank, and there is an advantage that the sediment filter part can be easily replaced.

Seventh, when the alkaline ionized water is filtered as described above, the hollow fiber membrane filter can be filtered while maintaining the alkalinity of the alkaline ionized water because the hollow fiber membrane filter passes the mineral component by using the filter medium of the precipitate filter unit as the hollow fiber membrane filter.

Ninth, since the flow rate is secured by the pump provided between the cold water tank and the water outlet, smooth water discharge can be achieved. In addition, the pump allows the alkaline ionized water to flow into the cold water tank to maintain the level of the cold water tank.
