The present invention relates to a water purifying device, and more particularly, to a water purifying device having a general water purification function and a water purification activation function of a water purifier while solving the inevitable bacterial contamination problem and the pH problem of purified water. It is about.

In general, water purifiers are largely classified into UF hollow fiber membrane water purifiers and reverse osmosis membrane water purifiers, among which reverse osmosis membrane water purifiers are commonly used.

Reverse osmosis membrane water purifier of reverse osmosis water purification system is known to be superior to other water purification methods developed so far in the removal of contaminants. However, the purified water passed through the reverse osmosis membrane filter in the reverse osmosis membrane water purifier tends to have a lower pH than the raw water due to the excellent purification ability of the reverse osmosis membrane, and it is pointed out that the smell of the reverse osmosis membrane filter material and the taste of water are used at the beginning of use. .

To solve this problem, most manufacturers of reverse osmosis membrane water purifiers use activated carbon filters (also known as post-treatment activated carbon filters) after the reverse osmosis membrane filter, but the activated carbon filters are easily contaminated by bacteria in a short time and the contaminated bacteria are stored in the storage tank ( Since the reverse osmosis membrane water purifier is purified through fine pores, the amount of purified water is small and is adopted by almost all manufacturers of reverse osmosis membrane water purifiers. Therefore, the use of this activated carbon filter is a major cause of contaminating the purified water in the storage tank with bacteria. .

In addition, fine activated carbon dust generated in the activated carbon filter also flows into the storage tank and becomes a nutrient substance of bacteria, thereby promoting contamination of bacteria in the storage tank.

In addition, a general reverse osmosis membrane water purifier storage tank is made of plastic (ABS resin, PE resin, etc.), and the full amount of water is not 100% used at a time, and only a part of the water is used. In the process of mixing, they come into contact with air and become contaminated by germs.

As a result, even if the reverse osmosis membrane water purifier completely removes various contaminants in the water through the very fine pore reverse osmosis membrane filter, the problem of bacterial contamination in the activated carbon filter (alias: post-treatment activated carbon filter) after the reverse osmosis membrane filter is not fundamentally solved. Unless otherwise, bacterial contamination of purified water in storage tanks is an unavoidable problem.

Therefore, to solve this bacterial problem, most water purifier manufacturers recommend that consumers (users) clean the storage tank regularly (three to four times a month), which is difficult to carry out in reality and its effect is unknown. In addition, the UV lamp is installed inside the water purification system to pass water through it, but it does not have a perfect sterilization effect, and it is not caused by UV rays. New problems, such as corrosion problems, are not practical and are not a fundamental solution to bacterial contamination.

In addition, the UF hollow fiber membrane water purifier currently sold generally involves the same problems as the reverse osmosis water purifier. One of them uses an activated carbon filter (alias: post-treatment activated carbon filter) at the back of the UF hollow fiber membrane filter like the reverse osmosis water purifier, and secondly, the storage tank, although the amount of water purified by the UF hollow fiber membrane is much higher than that of the reverse osmosis membrane. It is designed as a system with. This shows that they have almost the same problems as the above problems that may occur in the reverse osmosis water purifier.

In addition, conventional water purifiers have a disadvantage in that they do not have mineral content and water taste, such as natural mineral water or underground rock water (for example, drinking spring water). It is related to the function.

It is easy to see that the raw water used in most water purifiers is tap water, and the source of the tap water is surface water, which does not have mineral content or taste like natural mineral water or underground rock water. In addition, since the role of the general water purifier is only a function of removing the contaminants in the water, the mineral content, taste of water, and benefits in the human body do not exceed the limits of the surface water.

It is an object of the present invention to solve the above-mentioned problems of the prior art, to solve the problem of pH drop or bacterial contamination occurring in a storage tank installed for the convenience of consumer due to the characteristics of the water purification system in the reverse osmosis membrane or UF hollow fiber membrane water purifier. It is to provide a water purification device for.

Another object of the present invention is to generate bacteria and activated carbon generated from the activated carbon filter (aka: after-treatment activated carbon filter) at the rear end of the reverse osmosis membrane filter or UF hollow fiber membrane filter, which is installed in a general order in most water purification systems. It is to provide a water purifying device for solving the problem of fine dust.

Still another object of the present invention is to provide a water purification device that controls the mineral content of purified water, improves water taste, and activates water molecules to convert purified water into functional active water beneficial to the human body.

In order to achieve the above object, the present invention provides a first carbon filter for removing contaminants of raw water, a functional ceramic filter for activating primary purified water passing through the first carbon filter through a functional ceramic ball, and the functional ceramic. A second carbon filter for removing contaminants remaining in the purified water activated by the filter, and a hollow fiber membrane filter for removing bacteria and fine dust generated in the secondary purified water passing through the second carbon filter; The functional ceramic filter is characterized in that one or more functional ceramic blocks made of functional ceramic balls are stacked.

According to one embodiment of the present invention, the functional ceramic block made of the antimicrobial ceramic ball is characterized in that each antimicrobial ceramic ball includes a silver (Ag) component to elute silver ions having an antimicrobial action during the purification process.

According to such a structure, the water purifying apparatus of this invention is a water purifying system of the UF hollow fiber membrane water purifier provided with the functional ceramic filter between a 1st carbon flutter (or a free carbon filter) and a 2nd carbon filter (or a post carbon filter). By mounting a ceramic filter (aka KW Wells Filter) in which functional ceramic blocks made of functional ceramic balls, such as energy activated ceramics, natural stone ceramics, pH adjusting ceramics, antibacterial ceramics, and KWT ceramics, are stacked on the rear of the first carbon filter, It completely solves the problem of degradation and bacterial contamination, and it is rich in minerals, has a good taste of water, and activates purified water to create a functional water that is beneficial to the human body, and has UF (or MF) hollow fiber membrane at the end of the water purification system. By mounting a hollow fiber membrane filter (or bactericidal or filtration filter), the post carbon filter attached to the rear of the functional ceramic filter By completely removing the bacterial life and differential binary which, to thereby completely cut off the bacteria and nutrient activated carbon fine powder of the bacteria get in storage tank for storing the jeongsusu.

Hereinafter, with reference to the accompanying drawings and diagrams a preferred embodiment of the water purifying apparatus of the present invention will be described in detail.

1 is a schematic illustration of a water purification system of the present invention comprising a functional ceramic filter (aka KW Wells filter).

According to the drawings, the water purifying apparatus of the present invention includes a sediment filter (1) for removing rust or suspended solids, first and second carbon filters (2; 4) for removing contaminants, and between these carbon filters. The functional ceramic filter 3 arrange | positioned and the hollow fiber membrane filter 5 for removing the foreign material of the said 2nd carbon filter are included.

As a result of the water purification process, water is introduced into the main body of the water purification system through a raw water supply hose connected to a tap (not shown in the drawing), and a sediment filter mainly for removing rust and suspended solids. As it passes (1), rust and solids are removed.

While passing through the first carbon filter (or pre-carbon filter) 2, chlorine, carcinogens, and organic compounds in the water are removed, and various kinds are passed through the functional ceramic filter (aka KW Wells filter) 3. Through the functional ceramic of this, water is activated, natural minerals are controlled to soften the taste of water, converted to weakly alkaline water, odors in the water are removed, and microorganisms such as bacteria are suppressed. Energy is activated by the radiation of far infrared rays.

Water passing through the functional ceramic filter (3) passes through the second carbon filter (4) to remove bad odors such as gas in the water, and the final stage of the 0.01 micron hollow fiber membrane filter (aka; UF membrane filter) (5) Microorganisms such as ordinary bacteria are completely removed and various contaminants in the water are filtered out, and mineral components beneficial to the human body are passed through to be converted into clean, safe and energy-rich water.

The purified water after the above treatment is stored in the storage tank 8 via the water level control safety device 6, and the purified water in the storage tank 8 is stagnant (when not using the water purifier) for a predetermined time, and extracted (the When the purified water is extracted through the use), the process is repeated when the purified water is introduced into the storage tank. In addition, the water moved from the storage tank (6) to the hot water tank (10) is converted to hot water and stagnated for a certain time (when not using a water purifier), extraction (when purified water is extracted by using the water purifier), inflow (storage) When new water is introduced into the tank).

Hot water is extracted through hot water coke through the hot water safety valve (11) during extraction.

In the water purification device of the present invention, the functional ceramic filter 3 plays a role of converting purified water into functional water that is beneficial to the human body by activating purified water as well as purified water of purified water.

The construction of such a ceramic filter is shown well in FIGS. 2 and 3.

FIG. 2 is a diagram showing the detailed configuration of various filters of the water purification device according to the present invention, and FIG. 3 is a diagram showing the detailed configuration of the functional ceramic filter 3.

According to the drawings, the purified water is removed through the hardened sediment cartridge 12 of the sediment filter 1 to remove rust components, suspended solids, and the like, and to remove the carbon block activated carbon 13 of the first carbon filter 2. As it passes, chlorine, carcinogens and organic compounds in the water are removed.

The functional ceramic filter 3 is composed of a plurality of functional ceramic blocks, each of which is made of a functional ceramic ball.

The functional ceramic block is a far-infrared radiation ceramic block made of energy-activated ceramic ball 14a, a mineral component made of natural stone ceramic ball 14b and a water taste adjusting ceramic block, a pH adjusting ceramic block made of pH adjusting ceramic ball 14c, and an antibacterial ceramic. An antibacterial ceramic block composed of balls 14d, and an anion-emitting ceramic block composed of tourmaline stone (KWT) ceramic balls 14e for activating water by making a cluster of water small, and the present invention is a part of these blocks. Or all of them.

The activated ceramic ball activates water by ceramic energy, makes water of high energy level, and activates cells of the human body by a large amount of far-infrared radiation. In addition, the cluster of water is made small to keep the redox potential low.

The natural stone ceramic ball elutes various minerals (calcium, sodium, potassium, magnesium, etc.) in the water to control the mineral components in the water and improve the taste of water.

The pH-controlled ceramic ball is composed of coral sand (coral sand), etc. as a main component, eluting minerals such as calcium to increase the pH of water, imparting cleaning power to water itself, and absorbing well in the human body.

The antimicrobial ceramic ball contains a small amount of silver component, so that the silver component is eluted during the water purification process, to suppress the generation of microorganisms and have a continuous antibacterial power. According to this antimicrobial effect, degassing and deodorization of water in water are performed.

The tourmaline ceramic ball releases anions in the water by contact or heating with water during the purification process by using the characteristic of the weak current generation, which is inherent in the natural tourmaline stone as a main component, and the water molecules are moments of the tourmaline component. It is electrolyzed into hydrogen ions and hydroxide ions by discharge. Accordingly, water exhibits a surface active effect, and the cluster of water is reduced by the influence of anions and far infrared rays.

By the action of such a ceramic filter, water passing through the functional ceramic filter is radiated in abundance with far-infrared energy in the energy-activated ceramic ball 14a, so that the clusters of water molecules become smaller and energy-activated. By eluting the mineral content, the mineral content in the water is controlled to maintain the mineral balance like natural mineral water and improve the taste of water, and the pH of the water is controlled in the PH adjusting ceramic ball 14c to form weakly alkaline water suitable for the body. The microbial contamination is prevented by the antimicrobial action of the antimicrobial ceramic ball 14d, and at the same time, secondary contamination of the microorganisms in a storage tank in which purified water is stored is prevented. And energy-rich functional active water through the radiation of far-infrared rays.

The antibacterial action by the antibacterial ceramic ball 14d in the storage tank in which purified water is stored is well illustrated in FIG. 4.

The silver ions (Ag +) eluted from the antimicrobial ceramic ball 14d maintain the antimicrobial activity by destroying cells by interacting with microorganisms, such as bacteria, secondaryly contaminated through air in the storage tank 6. Silver ions (Ag +) are reported to be more effective for sterilizing bacteria than other metal ions, and it has been found that silver ions (Ag +) in ppb units are harmless to humans, and drinking water using silver ions (Ag +) in Europe, etc. The sterilization treatment of is generalized as a water treatment treatment method. However, silver ion (Ag +) is a secondary contaminant (SECONDARY CONTAMINANT) in some countries, such as the United States, because the limit is less than 50ppb in the present invention, the antimicrobial ceramic cartridge storage tank in the present invention By dispersing silver ions uniformly in the tank, the microorganisms were effectively eluted (10ppb-15ppb) to maximize the antimicrobial effect and did not exceed 50ppb. Under these conditions, silver ions (Ag +) eluted from the antibacterial ceramic ball 14d slowly spread into the water in the storage tank, destroying and completely killing the metabolism of bacteria introduced by contact with external air, thereby completely killing the fresh water. Keep as.

As a result, the user is free from contamination problems such as bacteria even when the water purifier is in use or when the water purifier is not used for a predetermined time.

This is the result of selecting the water purifier used in each area arbitrarily. All the values were much higher than the standard bacteria (100 CFU / mL) of 『Eating Water』.
