Description

Electrolytic cartridge for water purifier

The present invention relates to an ion generating cartridge for a water purifier, and more particularly, a device for supplying general tap water or ground water separately from acidic water and alkaline water by using electrolysis, and in particular, all the parts are embedded in one cylindrical body. The present invention relates to an ionized water generating cartridge for an integrated water purifier, which can be used as a filter of a general household or commercial water purifier and is very easy to install and repair.

Conventionally, ionized water generating apparatuses of various structures using electrolysis have been introduced. Such ionized water generators are usually constructed with a structure in which an anode and a cathode are provided in an electrolytic cell, and an ion exchange membrane is disposed therebetween. Thus, when tap water is injected into the electrolyzer and power is applied, various mineral components present in tap water, that is, positive ions such as calcium, magnesium, potassium, etc., are collected around the cathode. In addition, negative ions such as chlorine, sulfuric acid, and sulfur collect around the anode.

In addition, since the hydrogen ions (H +) take electrons from the cathode to form hydrogen molecules (H ₂ ) and fly off into the air, the hydroxide ions (OH −) are increased and the water becomes alkaline. In the anode, since the hydroxide ion (OH-) provides an electrode to the anode to generate oxygen molecules (O ₂ ) and then flows into the air, the hydrogen ions (H +) increase and water becomes acidic. Thus, acidic water is generated in the electrolytic cell equipped with the positive electrode and alkaline water is produced in the electrolytic cell equipped with the negative electrode. In general, alkaline water is used for food, acidic water is discarded or stored separately and used for face wash or industrial use.

By the way, such ionized water generating device has a scale such as calcium, magnesium, potassium, etc. attached to the cathode when used for a long period of time, the electrolytic current is reduced, so that the electrolysis of acidic and alkaline water is not good. Therefore, a method of removing the scale attached to the cathode by inverting the voltage of the anode and the cathode every predetermined time has been introduced.

For example, Korean Patent Publication No. 1997-6468 (published date; 1997.04.28.) Applies an electric voltage between a first electrode and a second electrode separated by a diaphragm and electrolytically decomposes tap water to generate alkaline water and acidic water. Ionized water generator is introduced. The electrolytic ion water generating device includes an alkaline water outlet for extracting alkaline water, an acidic water outlet for discharging the acidic water, a first electrode chamber including the first electrode, a second electrode chamber including the second electrode, and the alkali water A first channel through which the electrolyzed water generated in the first electrode chamber flows between the outlet port and the first electrode chamber toward the alkaline water outlet, and the electrolyzed water generated in the second electrode chamber between the acidic water outlet port and the second electrode chamber; A second channel through which water flows toward the acidic water outlet, a third channel installed between the alkaline water outlet and the second electrode chamber, and flowing electrolytic water generated in the second electrode chamber toward the alkaline water outlet; Fourth water which flows the electrolyzed water produced in the said 1st electrode chamber toward the said acidic water outlet between an acidic water outlet and a said 1st electrode chamber. The third channel and the fourth channel are closed when the furnace and the first channel and the second channel are opened; and the third channel and the fourth channel are opened when the first channel and the second channel are closed. And a control means for operating the crossline valve so that the alkaline water is always taken out at the alkaline water outlet when the supply voltage between the first electrode and the second electrode is reversed. It features.

However, such an ionized water generating device has a problem that the overall structure is too complicated, and each component is dispersed, so that it is structurally unsuitable to be applied to a domestic water purifier.

Meanwhile, various filters for water purifiers that generate ionized water are also introduced. First, Korean Patent Registration No. 0604353 (Registration Date; 2006.07.18.) Introduces a method for producing calcium ionized water using shellfish, and a device thereof, including oyster shell, cockle, clam shell, sewage, Shells such as shellfish are calcined to produce calcium oxide, and calcium ionized water is prepared using a filter filled with calcium oxide. However, since calcium ionized water prepared using the calcium oxide filter is strongly alkaline, the acidity (pH) of calcium ionized water is adjusted to 5 to 10.5 so as to be suitable for drinking water by adding a strong acid, that is, acetic acid. There was a problem.

In addition, in Korean Patent Registration No. 0455034 (Registration Date; 2004.10.21.), A carrier made of a calcium compound which maintains the acidity (pH) of the water in alkaline water of 7 to 10 continuously when water is passed is provided. It is introduced. The carrier is prepared by using the lime powder obtained from the shell and the like, and the granules are calcined by heat treatment at 600 ~ 800 ℃ heat for 1 hour to 6 hours, mainly used as a filter for water purifier. However, such a conventional water purifier filter using an alkali carrier does not have a function of adjusting the acidity (pH), and there has been a demand for improvement.

In the present invention, the device is for supplying general tap water or ground water separately from acidic and alkaline water by using electrolysis, and in particular, all parts are built in one cylindrical body, so as a substitute for a filter for general household or commercial water purifier. The object is to provide an ionized water generating cartridge for an integral water purifier that is usable and very easy to install and repair.

In order to achieve the above object, the ionizer generating water cartridge for a water purifier of the present invention has an ion exchange membrane formed to be partitioned inside an electrolytic cell, and (+,-) electrode plates having different polarities are provided on both sides of the ion exchange membrane, and (+ A discharge port communicating with the polar electrolyte tank and discharging acidic water is provided, and a three-way switching valve is connected to the polar electrolyte tank and induces the discharge of alkaline water and acidic water, and includes an inlet formed at the bottom of the electrolytic cell. A cylindrical upper body; The upper part is detachably coupled to the bottom of the upper body, and the inner circumferential surface is detachably coupled to the inlet, and induces opening and closing of the three-way switching valve and the solenoid valve by applying power, Consists of a cylindrical lower body made of a PCB board is installed to control the inversion of the electrode plate polarity.

Therefore, the present invention separates the acidic water and alkaline water contained in tap water or groundwater by electrolysis in an electrolytic cell, and can be used as a filter for a domestic or commercial water purifier and is installed simply in a structure that separates the upper and lower parts. And replaceable effect.

In general, the filtration system of the water purifier widely used in homes, restaurants, public institutions, etc. consists of a sediment filter, precarbon filter, membrane filter, and postcarbon filter. Here, the sediment filter and the free carbon filter remove large particles of suspended solids and rust residues contained in raw water such as tap water or ground water, and the membrane filter removes various heavy metals, carcinogens or bacteria such as bacteria. Post-carbon filter removes the smell of purified water and blocks the growth of microorganisms. The purified water passing through the filter as described above is stored in the purified water tank, the cold water tank and the hot water tank, respectively, and is provided to the user through a cold water valve or a hot water valve if necessary.

The electrolytic ion water generating cartridge for water purifier according to the present invention is installed in such a filtration system, and is particularly suitable for use as a substitute for a membrane filter. However, the scope of the present invention is not limited to the above use.

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

상기에서 보는 바와 같이, 통상적인 기술원리로서 구체적인 설명은 하지 않으며, 전해조(130)내에서 알카리수와 산성수를 분리하기 위한 것이다.The ion exchange membrane 110 is also referred to as "Ion exchange membrane" in English, or in other words, a selective permeable membrane, as described in the Naver Encyclopedia. In the early 20th century, synthetic membrane research was carried out based on the theory of selective permeability of K. Myers. The resulting high ion exchange membranes have been put into practical use in various fields such as efficient concentration and desalination of electrolytes. The properties of the exchanger are basically the same as those of the granular exchanger, but at the same time, there are other properties and other uses are possible. When the exchange membrane is immersed in an electrolyte solution and the current flows through the solution, the cation exchange membrane passes the cations, but exhibits a close resistance of 100% for the passage of anions, and the anion exchange membrane shows the opposite phenomenon. When the two exchange membranes are combined properly, the electrolyte solution can be concentrated, desalted, and the like. In particular, it is used on a large scale for decontamination from seawater, and is also used for large-scale water treatment, such as beverage production.
