The present invention relates to an ion water purifier configured to supply alkaline water and acidic water by ionizing the supplied water, and more particularly, it is possible to discharge acidic water more easily and to prevent backflow of acidic water discharged. It relates to an ion water purifier.

Recently, environmental pollution due to various pollutions has emerged as the most important social problem. Among the various environmental pollutions such as air pollution, land pollution, and water pollution, especially the pollution of natural water such as river water, seawater, and hot spring water, restricts the use of tap water as drinking water. Is becoming a serious problem. Therefore, the water purifier that supplies the water after drinking the water with confidence so that the user can safely drink water is provided in homes, schools, workplaces, public offices, etc. In such water purifiers, cold water and hot water are usually selected according to individual preferences. Cold and hot functions are included.

Hereinafter, a conventional cold / hot water purifier will be described with reference to the accompanying drawings.

1 is a schematic diagram showing the configuration of a conventional cold and hot water machine.

As shown in FIG. 1, in the conventional cold / hot water purifier 10, the raw water supplied from the water pipe 11 through the raw water inlet pipe 11a is precipitated filter 12 and a pre-carbon filter 13. And it is purified in the process of passing through the filter unit consisting of a membrane filter (14: Membrane filter) and after-carbon filter (15: After-carbon filter). Thus purified water is separated and stored in the cold water tank 17 having a cooling means and the hot water tank 18 having a heating means, respectively, from the normal temperature storage tank 16 having the water level control device 16a. When the user's request is provided through the cold water discharge pipe (17a) and the hot water discharge pipe (18a) connected to the discharge cock 19 is provided as cold or hot purified water.

At this time, the configuration of the filter unit is changed in various ways depending on the purified water conditions and applications.

In addition, in modern medicine, as the cause of various adult diseases such as high blood pressure, diabetes, heart disease, etc. is found to be acidification of the constitution due to excessive intake of acidic foods, alkaline water is electrolyzed to improve the acid constitution to alkaline constitution. Ionizers to provide the latest has been developed and commercialized.

Hereinafter, a conventional ionizer will be described in detail with reference to the accompanying drawings.

2 is a schematic view showing the structure of a conventional ionizer.

As shown in FIG. 2, the conventional water ionizer 20 passes raw water supplied from the water pipe 11 through the raw water inlet pipe 11a provided with the solenoid valve 21 through a filter 22 having a simple structure. After the primary purification, the purified water is supplied into the electrolyzer 23 equipped with the diaphragm and at the same time, the negative current or the positive current flows through the diaphragm of the electrolyzer 23. The raw water is formed into alkaline water or acidic water by the electrolytic action generated inside the electrolytic cell 23, and the alkaline water or acidic water thus formed is supplied to the user through the ionized water supply pipe 25 and at the same time, Water is made of a structure to be discharged to the outside of the ionizer 20 through the discharge pipe (24).

Therefore, the user can use the alkaline water ionized in the electrolytic cell 23 for drinking water and the acidic water for washing and washing.

In addition, in order to solve the problem of users who demand ionized cold and hot water, an apparatus in which cold and hot water and ion water are formed integrally has been proposed (see Korean Utility Model Publication No. 199-742).

The ion cold / hot water beverage apparatus in which the hot and cold water and the ion water groups disclosed in the Utility Model Publication No. 199-742 are integrally formed has a water purifier → an electrolytic cell → a cooling tank in view of the cold and hot water and the ion water treatment step. In other words, the electrolytic cell is installed at a position prior to the cooling tank storing the coolant.

The well-known ion cold / hot water drink apparatus purifies tap water in a water purifier, separates purified water into acidic water and alkaline water in an ionization electrolytic cell, and alkaline water is supplied to and stored in a cooling tank and a hot water tank. Water through cold or hot water coke as required by the user. In other words, the alkaline ionized water generated through the electrolytic cell is cooled while being primarily stored in a cooling container, so that the user can open the cold water tap and receive the ionized water.

However, in the apparatus, the alkaline ionized water generated through the ionizer is stored for a long time in the cooling tank and the hot water tank which is the ionized water storage tank until the user withdraws, and the ionic component of the alkaline ionized water stored in the cooling tank is changed over time. As it disappears, the pH concentration becomes more and more neutral. In other words, the ionized ion component is unstable compared to the original bound state, and has a property of returning to a stabilized state when there is a binding factor or energy is applied. There is a problem that disappears over time.

In order to solve the above problems, an ion water purifier composed of a water purifier → a cooling tank → an electrolytic cell has been proposed. In this case, the problem of changing the pH of the water supplied to the user can be solved. However, if the cold water stays in the electrolyzer for a long time when the water is not used for a long time, the temperature of the cold water rises. There is a problem that is supplied to the user in a cold state. In addition, some residual water is left between the diaphragm in the electrolytic cell after cold water extraction. When the external temperature is high, such as in summer, the residual water is maintained at a high temperature of about 25 to 30 degrees. There is also a problem that the temperature rises.

In addition, the conventional cold and hot ionized water drink apparatus is not easy to extract acidic water when the drainage line for discharging the acidic water is long, there is also a problem that the electrolytic efficiency is lowered when the amount of acidic water is reduced.

The present invention has been proposed to solve the above problems, it is possible to maintain a constant pH of alkaline water, to supply cool water at all times even if not used for a long time, so that the acidic water can be discharged more easily It is an object to provide an ion water purifier constituted.

Hereinafter, an embodiment of an ion water purifier and an ion water purification method according to the present invention will be described with reference to the accompanying drawings.

3 is a schematic diagram showing the configuration of an ion water purifier according to the present invention.

As shown in FIG. 3, the ion water purifier according to the present invention includes a filter unit 100 for filtering and purifying water introduced from the outside, and room temperature water for storing filtered and purified water through the filter unit 100. The tank 200, the cooling tank 300 for receiving a predetermined amount of water stored in the normal temperature water tank 200 and cooled, and the electrolytic cell 400 for ionizing the water cooled by the cooling tank 300 with alkaline water and acidic water. ), And the coke 500 which receives the alkaline water generated by the electrolytic cell 400 through the alkaline water supply passage 800 and discharges it to the outside, and the water introduced into the electrolytic cell 400 is longer than the time set by the user. When staying in the electrolytic cell 400, the flow path switching valve 810 which is operated to drain the water in the electrolytic cell 400 to the outside, and a drain passage for discharging the acidic water generated by the electrolytic cell 400 to the outside ( 900). Therefore, the alkaline water generated in the electrolytic cell 400 is supplied to the user through the alkaline water supply passage 800 and the coke 500 as the user operates the coke 500, and the acidic water generated in the electrolytic cell 400 is drained. It is discharged to the outside through 900.

As described above, when the electrolytic cell 400 is provided at the rear end of the cooling tank 300, the extraction pressurizing device is not required, and thus, manufacturing costs can be reduced by reducing the number of parts, and vibration and noise are not generated.

The filter unit 100 may include a first filter 110 for removing a relatively bulky floating material such as dust or various debris among foreign matters contained in groundwater, a relatively small chemical substance among foreign matters contained in groundwater, and It is configured to include a second filter 120 for removing microorganisms and the like.

At this time, the first filter 110 is applied as a sediment filter for removing suspended substances such as dust or debris contained in the water supplied through the fine filter of about 5 microns.

In addition, the second filter 120 is a pre-carbon filter 122 that removes harmful chemicals such as carcinogens (THM), synthetic detergents, insecticides, and chlorine components by using an adsorption method of the active plate, and 0.0001 micron Membrane filter 124 to filter out heavy metals such as lead arsenic, as well as sodium, viruses, radioactive materials, and the posterocarbon filter 126 to remove unpleasant taste, smell, pigment, etc. It is configured to include.

Since the sediment filter, the precarbon filter 122, the membrane filter 124, and the poster carbon filter 126 are commercially available as filters of a conventional water purifier or an ionizer, detailed description thereof will be omitted. .

The water stored in the room temperature water tank 200 is introduced into the cooling tank 300 through the separator 210, and the water cooled by the cooling tank 300 flows into the electrolytic cell 400 through the cold water feed valve 310. It is configured to be. In this case, since the separator 210 and the cold water feed valve 310 are the same in configuration and operation as the separator and the cold water feed valve applied to the conventional ion water purifier, a detailed description thereof will be omitted.

In addition, for the case where the user wants the ionized water that is not coldly cooled, the room temperature water tank 200 and the electrolytic cell 400 is configured to be directly connected by the purified water feed valve 700. That is, the water stored in the room temperature water tank 200 may be supplied directly into the electrolytic cell 400 without passing through the cooling tank 300 so that ionized water that is not cooled down may be supplied to the user.

Water introduced into the electrolytic cell 400 is ionized into alkaline water suitable for drinking water and acidic water suitable for washing water, respectively. Alkaline water is delivered to the coke 500 through the alkaline water supply passage 800 and supplied to the user for drinking water, and the acidic water is drained to the outside through the drainage passage 900. In this case, the user may separately collect only acidic water drained to the outside through the drainage passage 900 and use the washing water.

At this time, if the water cooled by the cooling tank 300 is directly supplied through the cork 500 after being ionized by the electrolytic cell 400, the water supplied to the user can be maintained in a cool state as it is, If there is no water discharge request, the cooled water stays warm in the electrolyzer 400 for a long time, so it is warmly lukewarm by the external temperature, so even if the user wants coldly cooled ionized water in the electrolyzer 400 or the alkaline water supply passage 800 There is a problem that the warm water is supplied to the user.

In order to solve the above problems, the ionizer according to the present invention is a case in which water introduced into the electrolytic cell 400 stays in the electrolytic cell 400 for more than a time set by a user, that is, water cooled in the cooling tank 300. When warmly warmed in the electrolytic cell 400 or the alkaline water supply passage 800, the water in the electrolytic cell 400 is configured to drain to the outside. For the operation as described above, the alkaline water supply passage 800 and the drainage passage 900 are connected by the washing passage 820, the electrolytic cell 400 in the portion where the alkaline water supply passage 800 and the washing passage 820 is connected. Is provided with a flow path switching valve 810 for selectively guiding alkali water in the coke 500 or the drain passage 900. Therefore, the alkaline water generated inside the electrolytic cell 400 may be delivered to the coke 500 and supplied to the user according to the operation of the flow path switching valve 810, or may be delivered to the drainage flow path 900 through the cleaning flow path 820. It may be discharged to the outside.

In addition, the cold water feed valve 310 supplies the cool water from the cooling tank 300 to the electrolytic cell 400 by the amount that the warmly warmed water in the electrolytic cell 400 is drained by the flow path switching valve 810. Done. As described above, the ion purifier according to the present invention is configured to periodically drain the warmly warmed water and fill the electrolytic cell 400 with coldly cooled water, so that the user can always supply coolly cooled water even when not used for a long time. There is an advantage.

At this time, when the alkaline water generated in the electrolytic cell 400 flows into the drainage flow path 900 through the washing flow path 820, the acidic water generated in the electrolytic cell 400 is drained because the water pressure in the drainage flow path 900 is increased. It may not be discharged to the outside through the flow path (900). If the acidic water is not smoothly discharged as described above, there is a problem that pH control in the electrolytic cell 400 cannot be normally performed. In order to prevent such a phenomenon, the pump 910 for applying pressure to the water passing through the drain passage 900, that is to generate a drain pressure so that the drainage of the water through the drain passage 900 more easily It is composed. Since the water in the drain passage 900 is forcibly discharged to the outside by the operation of the pump 910, even if alkaline water is introduced into the drain passage 900 through the washing passage 820, the acid generated in the electrolytic cell 400 Water can be easily discharged to the outside. In particular, when the length of the drainage passage 900 is long, the acid water may not be smoothly drained due to an increase in the frictional head in the pipe. The pump 910 is disposed on the drainage passage 900 as in the present embodiment. If provided, since the acid water is easily drained regardless of the length of the drain passage 900, there is an advantage that the ion water purifier can be installed more freely.

In general, since the ion water purifier does not have a large amount of acidic water, the pump 910 is operated at a low speed. When the pump 910 is operated at an excessively low speed, i.e., below the rated power, the pump 910 may fail. Triggered. Therefore, the flow rate draining unit 900 is further provided with a flow rate adjusting unit 930 so that the pump 910 can operate at the rated output while maintaining the flow rate discharged through the drain passage 900 at a constant level. Do.

The arrangement order of the pump 910, the non-return check valve 920, and the flow rate control unit 930 is not limited to the present embodiment, and may be freely changed according to various conditions.

At this time, the pump 910, the cavitation (cavitation) is generated, the intake of the suction pipe and the idle flow due to the lack of flow (Minimum Flowrate) is made, or the water drainage phenomenon due to the reverse flow when the pump is stopped It is preferable to be applied as a self-priming pump that can operate stably even if generated. When the pump 910 is applied as a self-suction pump, if only the first full water is made in the pump 910, even if the air suction operation continues to operate and strong magnetic force is generated, so that the self-suction flow of liquid is possible, more stable acid The advantage is that the water can be discharged to the outside. Since such a self-priming pump is commercially available in various industrial fields, a detailed description thereof will be omitted.

In addition, the ion water purifier according to the present invention, between the cooling tank 300 and the electrolytic cell 400 in order to minimize the amount of cold air to the outside while the water cooled in the cooling tank 300 is introduced into the electrolytic cell 400. In other words, the cooling tank 300 and the electrolytic cell 400 are tightly coupled to each other so that the length of the flow path is minimized, and the cooling tank 300 and the electrolytic cell 400 prevent the cool air of the water filled therein from escaping to the outside. In order to be wrapped by the heat insulating material 600 is preferable. At this time, the material of the insulating material 600 surrounding the cooling tank 300 and the electrolytic cell 400 may be applied to any material as long as the material can lower the thermal conductivity.

As such, when the cooling tank 300 and the electrolytic cell 400 are coupled to be in close contact with each other, and are configured to be wrapped by the heat insulating material 600, the cooling water 300 in the cooling tank 300 and the electrolytic cell 400 leaks to the outside. Since it can prevent, the cooling efficiency is improved.

The present invention has been described in detail using the preferred embodiments, but the scope of the present invention is not limited to the specific embodiments, and should be interpreted by the appended utility model registration claims. In addition, those of ordinary skill in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

Ion water purifier according to the present invention, it is possible to maintain a constant pH of the ionized alkaline water, to supply cool water at all times even if not used for a long time, and to easily discharge acidic water even if the drainage passage is long There is an advantage.
