Description

TECHNICAL FIELD [0001] The present invention relates to an ionizer having a function of removing lime components, and a control method thereof. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002]

The present invention relates to an ionizer for electrolyzing water and separating the water into alkaline water and acid water.

In general, water in the natural state melts various substances such as calcium, magnesium, and iron in contact with air, soil, and rock, and various harmful substances are contained in water due to environmental pollution caused by industrialization, Most of the existing natural water is unsuitable for drinking water.

Most harmful substances mixed in water are usually larger than water molecules. Therefore, it is possible to remove most of them by using a filter having an appropriate size of holes. In the water purifier using a filter, an activated carbon filter, an ultrafiltration filter, a nanofilter, And so on.

In recent years, the use of water purifiers that remove alkaline water by electrolyzing water has been spreading.

An ionizer is a device that electrolyzes water to electrolyze and ionizes it. The general principle is that the water is put in an electrolytic cell provided with a diaphragm between the cathode and the anode, and the electrolytic water is electrolyzed by flowing the DC electricity. At this time, alkaline ions such as calcium ions, magnesium ions, potassium ions, and sodium ions are collected on the cathode side to generate alkaline water. Acid ions such as chloride ion and sulfur ion are collected on the anode to generate acidic water.

On the other hand, in the case of many calcareous regions such as Europe, China, and the Americas, the water contains a lot of lime components, and conventional water purifiers and ionizers do not effectively remove lime components.

In the case of a water purifier, the water is purified through a filter which removes the lime component, but the lime removal performance is remarkably deteriorated, and in the case of the ionizer, the acidity is low due to the lime component. As the lime component is adsorbed on the electrode plate, the electrolytic capacity of the water is lowered and the acidity and the alkalinity are lowered. As a result, the performance of the ionizer is deteriorated.

In order to remove the calcite deposited on the electrode plate of the electrolytic cell, a method of washing the calcined periodically by using a method of reversing the electricity is also used. However, by this method, it is possible to remove the calcite residue deposited in the electrolytic cell smoothly There is a limitation in realizing an ionizer having a higher performance than a conventional ionizer.

Reference numeral 95 denotes a display window for displaying the operation and control status of the ionizer using an LCD or the like.

The main components of the ionizer according to one embodiment of the present invention will now be described in detail with reference to FIGS. 1 and 2. FIG.

First, the raw water supply unit 10 is a part to which raw water such as a water line is supplied, and has a valve device capable of selectively supplying water to the filtration tank 20 or the cleaning water supply device 80, do.

In the embodiment of the present invention, the line to which the raw water is supplied is branched into lines L1 and L2, which are connected to the filtration tank 20 and the washing water supply device 80, And shows a configuration of a valve device in which an accommodating solenoid valve 11 and a cleaning solenoid valve 15 are respectively installed.

 It is preferable that the ion accommodating solenoid valve 11 and the cleaning solenoid valve 15 are configured to be automatically operated according to the signal of the main control board 91 constituting the control unit 90. [

It is also possible to provide only one valve structure at a branch point in the raw water supply line without selecting the ion containing solenoid valve 11 and the cleaning solenoid valve 15 so as to select or shut off the flow path.

Next, the filtration tank 20 is provided with various known filter elements capable of filtering out foreign matter, so that foreign matter contained in the raw water can be filtered. For example, the sediment filter 21, the pre-filter 22, the nanofilter 23, and the post filter 24 are sequentially installed in the filtration tank to remove impurities such as impurities and harmful substances contained in the raw water Can be configured. Since most of the lime component is not removed from the filter member, the lime component is configured to be removed from the first electrolytic bath 40, which will be described in detail later.

Next, the first electrolytic bath 40 and the second electrolytic bath 50 will be described.

Conventionally, mainly one electrolytic cell is used to generate ionized water. However, in the present invention, ionized water can be generated using two electrolytic baths 40 and 50, and in particular, foreign substances including lime components are more effectively removed So that ionized water can be generated. For this purpose, the present invention is characterized in that the size of the electrode plate constituting the first electrolytic bath 40 is made larger, thereby facilitating the scale deposition by the electrolysis reaction when the water passes through the first electrolytic bath 40, Most of the lime component is removed, and the water from which the lime component has been removed is introduced into the second electrolytic bath 50 so that the ion exchanger can be generated through the electrolysis reaction.

In summary, the first electrolytic bath 40 is a pretreatment electrolytic cell for the purpose of removing lime components by electrolysis, having a relatively large electrode plate larger than the electrode plate provided in the second electrolytic bath 50, 50 is an outlet electrolytic cell for electrolyzing again the water from which the lime component has been removed in the first electrolytic bath 40 to generate alkaline ionized water.

The first electrolytic bath 40 and the second electrolytic bath 50 will be described in more detail.

2 is an exploded perspective view showing a first electrolytic bath 40 according to an embodiment of the present invention.

Referring to FIG. 2, the first electrolytic bath 40 includes a cover 41 having an inlet and an outlet, an electrode plate 46 having a plurality of pairs arranged at predetermined intervals to perform electrolytic decomposition in the cover 41, A membrane 47 disposed between each pair of electrode plates 46 and a clearance plate 48 disposed between the both sides of the membrane 47 and the electrode plate 46 to form a flow path space.

The cover 41 has a structure in which the upper cover 42 and the lower cover 43 are assembled together.

The upper cover 42 has an inlet 44 through which the line L3 connected to the filtration tank 20 is connected and an upper inlet 43 connected to the lower side of the second electrolytic bath 50 And an outlet 45 to which the line L4 is coupled is constituted. The inlet 44 is preferably positioned on one side of the upper cover 42 and is configured to be uniformly sprayed and evenly distributed as the water flows into the cover 41, It is preferable that the filter is located at the lower central portion so that the foreign matter filtered water and the immersion material can be smoothly discharged during cleaning. At this time, the bottom surface of the lower cover 43 is preferably inclined toward the discharge port 45 as illustrated in the drawing.

Since each of the pair of electrode plates 46 is an electrolytic cell in which the first electrolytic bath 40 is not an electrolytic cell for directly generating ionized water but is an electrolytic bath for immersing and removing lime components and the like, And an electrode plate (46) made of the same material. However, the present invention is not limited thereto, and various known electrode plates 46 can be applied by depositing and removing lime components through electrolysis.

The membrane 47 is configured to act as a membrane between a pair of electrode plates so that the ions to be electrolyzed are separated and smoothly deposited. That is, the electrolytic calcium ions, sodium ions, etc., which are electrolytically decomposed by the membrane 47, are prevented from staying on the (+) pole side of the electrode plate 46, Thereby being immersed in the electrode plate and facilitating the immersion of the ions on the surface of the electrode plate 46.

The clearance plate 48 preferably has a structure in which the support bars 49 are arranged side by side at regular intervals in a rectangular frame having a predetermined thickness.

In addition, the first electrolytic bath 40 preferably includes a single flow channel L4 connected to the second electrolytic bath 50, referring to FIG. That is, water separated into alkaline water and acidic water by the electrolytic action in the first electrolytic bath 40 is supplied to the second electrolytic bath 50 in a state in which they are combined again through the single outlet port 45 and the single flow path L4 It is preferable to be constructed so as to be able.

Next, it is preferable that the second electrolytic bath 50 is formed to be relatively smaller in size than the first electrolytic bath 40 described above, and the overall configuration is the same as or similar to the configuration of the first electrolytic bath 40, An electrode plate, a membrane, a clearance plate, a cover, and the like.

Unlike the first electrolytic bath 40, the electrode plate formed in the second electrolytic bath 50 is preferably made of platinum-coated electrode plate on titanium.

The second electrolytic bath 50 may be separately connected to the alkaline water outlet channel 75 and the acidic water outlet channel 71 so that the alkaline water and the acidic water generated by electrolysis may be separately discharged.

Next, the washing water supply device 80 supplies cleansing water mixed with organic acid such as citric acid to the first electrolytic bath 40 and the second electrolytic bath 50 to supply the washing water to the first electrolytic bath 40 and the second electrolytic bath 50 So that the scale deposited on the electrode plate can be removed. For this purpose, the washing water supply device 80 is constructed in such a manner as to bypass the filtration tank 20 between the cleaning solenoid valve 15 and the first electrolytic bath 40 as described above.

The cleaning water supply device 80 is preferably provided with a citric acid filter, which is one of the organic acids, so that the raw water can be supplied to the first electrolytic bath 40 together with the raw water.

The flow path switching device 60 is configured to open and close the line on the discharge path 77 in accordance with a signal from the control unit so that water flows from the first electrolytic bath 40 to the second electrolytic bath 50 And the water in the first electrolytic bath 40 and the second electrolytic bath 50 is opened to be discharged to the outside through the discharge flow channel 77 during the drain operation.

That is, when the water is normally supplied, the flow path switching device 60 is arranged such that water flows only toward the flow path from the first electrolytic bath 40 to the second electrolytic bath 50 during the outflow operation and the discharge flow path 77 is closed When the drainage operation, that is, the water supply is stopped, the device in the flow path switching device 60 operates according to the signal of the control unit 90 to open the discharge flow path 77, The materials immersed in the electrode plate 46 together with the water in the second electrolytic bath 50 are configured to be discharged to the outside through the discharge channel. At this time, it is preferable to supply the opposite electricity to the electrode plates of the electrolytic baths 40 and 50 so that the substances deposited on the electrode plates of the electrolytic baths 40 and 50 are separated.

A control method of the ionizer according to an embodiment of the present invention will now be described.

First, referring to Fig. 3, an outgoing operation for taking out the ionized water will be described.

When only the ion containing solenoid valve 11 is opened in a state in which the cleaning solenoid valve 15 is closed in accordance with the signal from the control unit 90, the raw water flows into the filtration tank 20 through the ion receiving solenoid valve 11, The foreign substances and harmful substances are removed through the four stages of filters 21, 22, 23, and 24 in the electrolytic cell 20 and then introduced into the first electrolytic bath 40.

The water introduced into the first electrolytic bath 40 is electrolyzed when passing between the pair of electrode plates 46, so that foreign substances such as lime components are deposited on the electrode plate side, and water is ionized and discharged through the discharge port 45 2 is discharged to the electrolytic bath 50 side. At this time, electrolyzed water in the first electrolytic bath 40 is separated into alkaline water and acid water, but is mixed again when discharged through one outlet 45, and then flows into the second electrolytic bath 50.

The water having passed through the first electrolytic bath 40 and having the lime component removed is electrolyzed again in the second electrolytic bath 50. At the same time, foreign substances such as lime, which have not been removed from the first electrolytic bath 40, And the secondary removal is carried out.

Thereafter, water is ionized into alkaline water and acidic water by the electrolytic action in the second electrolytic bath 50, and then separated from the water through the alkaline water outlet flow path 75 and the acidic water outlet flow path 71, respectively.

Next, with reference to FIG. 4, a description will be given of the drainage operation performed when the ion water outflow operation is stopped.

It is preferable that the drainage operation is automatically performed when the ionized water discharge operation is stopped.

In other words, when the user or the like stops taking out the ionized water, the ion accepting solenoid valve 11 is closed in accordance with the signal of the control unit 90, and the discharge flow path 77 is opened while the flow path switching device 60 is operated. At this time, the cleaning solenoid valve 15 is kept closed so that the inflow of raw water into the cleaning water supply device 80 as well as the filtration tank 20 is completely blocked. It is also preferable to control the water discharge switching device 30 to be opened together.

In addition, the power supplied to the electrode plates of the first electrolytic bath 40 and the second electrolytic bath 50 is reversed. When the power is applied in reverse, the substances deposited on the electrode plate are easily separated from the electrode plate.

When the flow path switching device 60 operates in this state and the discharge flow path 77 is opened, together with the water in the first electrolytic bath 40 and the second electrolytic bath 50, 77, the basic washing operation of the first electrolytic bath 40 and the second electrolytic bath 50 proceeds.

Finally, referring to Fig. 5, the cleaning operation will be described.

When a certain amount of water is taken out, a separate cleaning operation is performed to remove foreign matter such as lime deposited in the first electrolytic bath 40 and the second electrolytic bath 50.

The ion accepting solenoid valve 11 is closed and the cleaning solenoid valve 15 is opened according to the signal of the control unit 90 for the cleaning operation. The drain switching device (30) and the flow path switching device (60) are operated so as to block the flow path for draining to the outside.

Here, the cleaning operation signal of the control unit 90 may be a method of manually operating the user, a method of operating the automatic operation, or the like. The manual operation is usually made possible by operating a manual operation button such as a switch. Preferably, the automatic operation is performed when the scale is deposited on the electrode plate of the electrolytic cell at a predetermined level or more so that the electrolytic function is significantly lowered. The automatic operation is preferably performed by using a sensor such as an ORP (Oxidation Reduction Potential) The degree of reduction is monitored. If it is determined that the ORP value is lowered and the scale is increased to a predetermined value or higher in the electrolytic cell, the cleaning operation is performed by allowing the raw water to flow into the cleaning water supply device 80 automatically.

In addition, the automatic operation may be configured such that the cleaning operation is automatically performed when a predetermined amount or more of water is supplied or dispensed according to the amount of water supplied from the raw water supply unit 10 or the amount of water to be finally dispatched.

As the cleaning solenoid valve 15 is opened, the water that has flowed into the cleaning water supply device 80 passes through the citric acid filter, and the water that has passed through the cleaning water supply device 80, And then flows into the electrolytic bath 40.

At this time, the power supplied to the electrode plate of the first electrolytic bath 40 is reversely provided so that the substances immersed in the electrode plate in the first electrolytic bath 40 can be easily separated from the electrode plate.

In this state, the water containing citric acid introduced into the first electrolytic bath 40 reacts with foreign substances such as lime deposited on the electrode plate 46 in the first electrolytic bath 40, The first electrolytic bath is cleaned while the scale is removed. 6 and 7 are photographs showing the state before cleaning (FIG. 6) and after cleaning (FIG. 7) of the electrode plate provided in the first electrolytic bath 40. FIG.

Subsequently, the water containing citric acid, which has passed through the first electrolytic bath 40, passes through the second electrolytic bath 50 and likewise cleans the electrode plate on which substances such as lime are deposited, As shown in FIG. At this time, the power supplied to the electrode plate of the second electrolytic bath 40 is reversed.

8 and 9 are photographs showing the state before cleaning (FIG. 8) and after cleaning (FIG. 9) of the electrode plate provided in the second electrolytic bath.

When the cleaning of the electrode plates of the first electrolytic bath 40 and the second electrolytic bath 50 is completed in this way, the cleaning solenoid valve 15 is closed and the ion containing solenoid valve 11 is opened, So that foreign substances such as citric acid remaining in the first electrolytic bath 40 and the second electrolytic bath 50 and the flow path through the washing water are washed away.

A normal heading operation can be performed when a predetermined time has elapsed after the foreign object is rinsed by using the flow of water during the heading operation.

As described above, the technical ideas described in the embodiments of the present invention can be implemented independently of each other, and can be implemented in combination with each other. While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art.
