Description

Water purifier connected to water pipe

The present invention relates to a water pipe connection type water purifying apparatus, and more particularly, to a water purifying apparatus installed at a discharge port side of a meter connected to a water supply pipe entering indoors to purify water supplied into a home.

Korea's general industry developed very fast, and the water supply rate increased from 17.1% in 1961, per capita water supply to 102 liters in 2001 to 87.8% in 2001, per capita water supply to 374 liters in 2005. Water supply rate rose to 95%.

Along with the water supply rate, water pollution caused by environmental pollution is a serious problem, and various harmful substances are detected in tap water.

The detection of these harmful substances is not related to the discharge of wastewater and air pollutants generated by various industries in Korea with high population density.

In addition, in the existing piping system composed of cast iron pipe, the iron component is dissolved and escaped by the water flowing to the inner wall of the cast iron pipe, the iron component is oxidized in the process to form iron oxide.

In this case, if the cast iron pipe of the piping system is severely corroded and the iron oxides are entangled with each other, it will not only partially block the inside of the cast iron pipe and reduce the water pressure, but also the iron components will be entangled with each other to form red rust, which is dissolved in water again. This is a problem.

The inside of the pipe has a problem such as microorganisms inhabit and multiply and cause serious damage to human health with an unpleasant odor due to the occurrence of slime or scale.

Due to the above problems, most households avoid drinking water and drink groundwater or commercially available bottled water instead of tap water or use water purifiers.

However, boiling tap water every time or using groundwater is quite cumbersome, and the cost of using commercially available bottled water is a problem, and most households currently use water purifiers for drinking.

However, in addition, various water purifiers widely used in Korea are more unstable than tap water due to contamination by microorganisms in long-term use of odors, trihalomethane, bacteria, flavors, natural organic substances, and ionic substances in water. The supply of water is a social problem.

In addition, since only drinking water is purified, tap water used for cooking, washing vegetables and fruits, and washing and bathing is not safe because it eventually comes into contact with the human body.

Republic of Korea Patent No. 0632703 discloses a water treatment apparatus for a water supply facility, the main components are a water meter, a distribution fixing unit, a filtration unit, and a scale booster.

However, the water treatment device can filter out foreign substances in raw water, but has a problem in that it cannot remove various bacteria or microorganisms contained in water.

In addition, the zinc plate embedded in the scale booster has a risk that zinc, a kind of heavy metal, is contained in the raw water. These heavy metals are very dangerous because even if they accumulate in the body, they are not excreted well and accumulate in proteins in our body and cause side effects over a long period of time.

An object of the present invention is to provide a water purifier that can be used to purify all the water supplied to the home by installing one water purifier, which is created to improve the above problems.

Another object of the present invention is to provide a water purification device capable of preventing corrosion and scale formation of water supply pipes without the risk of heavy metals by magnetizing raw water.

Another object of the present invention is to provide a water purification device that can be safely drinking by removing various bacteria or viruses contained in the raw water.

Water purifying pipe connection type water purifying apparatus of the present invention for achieving the above object is connected to the discharge pipe of the meter installed in the water pipe entered into the indoor and the hollow filter housing; An annular filter unit embedded in the filter housing and having a cylindrical hollow in the center thereof; And a magnet installed in the hollow of the filter unit, wherein the filter unit is formed of a plurality of filters arranged in concentric layers, the outermost layer of which is formed of a ceramic filter, and the inner side of the ceramic filter having a sediment filter. The inner side of the sediment filter is characterized in that the carbon filter is formed sequentially.

The ceramic filter is formed of a ceramic containing 5 to 10 parts by weight of monazite, 2 to 5 parts by weight of tourmaline and 0.05 to 0.1 parts by weight of silver nano, based on 100 parts by weight of germanium.

It is installed in the filter housing is characterized in that it is further provided with a light sterilization lamp for sterilizing water by irradiating light.

The light sterilizing lamp is a light emitting diode that irradiates ultraviolet light, and a photocatalyst coating layer activated by the ultraviolet light is formed inside the filter housing.

The filter housing has a hollow cylindrical body, a first cap having a raw water inlet pipe coupled to one side of the body and formed from the center to the edge, and a purified water outlet pipe coupled to the other side of the body and formed at the center thereof. A second cap,

A light transmission tube connected to the purified water outlet pipe of the second cap of the filter housing; And a lamp unit for sterilizing the purified water by irradiating the transfer pipe with light.

The lamp unit has a closed and hollow cylindrical lamp housing on both sides, and the ultraviolet lamp is installed in the inner center of the lamp housing, the transfer tube is formed in a spiral surrounding the outer surface of the ultraviolet lamp It features.

As described above, according to the water supply pipe connected water purifier according to the present invention, by installing in the water supply pipe entering the indoor, it is possible to effectively purify all kinds of water required in the home such as drinking water, washing water, bath water, and living water as well as drinking water. Can be.

In addition, by magnetizing raw water using a magnet, corrosion and scale formation of the water supply pipe can be prevented without the risk of heavy metals, thereby preventing the purified water from being contaminated by the pipe.

In addition, it is possible to sterilize various bacteria or viruses contained in raw water by using an ultraviolet lamp, and in particular, in the case of using a light emitting diode, power consumption is low, volume is small, durability and impact resistance is excellent, and can be effectively sterilized.

Hereinafter, with reference to the accompanying drawings will be described in more detail a water pipe connection type water purifying apparatus according to a preferred embodiment of the present invention.

1 is a perspective view illustrating a state in which a water pipe connection type water purifier according to an embodiment of the present invention is connected to a meter, and FIG. 2 is a cross-sectional view of the water purifier of FIG. 1.

1 and 2, the water pipe connection type water purification device 10 of the present invention can be installed in connection with the water supply pipe anywhere in the middle of the water supply pipe 40 entered into the indoor, but can easily secure the installation space It is preferable that the inside of the meter box can be connected to the meter 50.

The water purifying device 10 of the present invention is connected to the discharge pipe 60 of the meter 50, the filter housing 95 into which the raw water is introduced and the purified water is discharged, and the filter housing 95, which is built in the filter housing 95, The filter unit 400 for filtering foreign substances, the magnet 500 for magnetizing the purified water, and the light sterilization lamp 600 for removing bacteria and microorganisms in the purified water.

The filter housing 95 has an open and hollow cylindrical body 100 at both sides, and the first cap 200 is screwed to the left side of the body 100. The first cap 200 is biased from the center to the edge is a raw water inlet pipe 210 is formed. This is to ensure the space in which the first ultraviolet lamp 600 is installed in the center of the first cap 200 and to allow the raw water to flow in from the outside of the filter unit 400. The raw water inlet pipe 210 of the first cap 200 is connected by the discharge pipe 60 of the meter 50 and the flange 70.

The second cap 300 having the water purification pipe 310 formed at the center of the main body 100 is screwed to the main body 100. The purified water outlet pipe 310 of the second cap 300 is the purified water is discharged as the purified water outlet pipe 310 is connected to the water supply pipe pipe 80 and the flange 71 to enter the home.

The filter unit 400 is embedded in the filter housing 95, and is formed in an annular shape in which a cylindrical hollow is formed in the center of the filter unit 400. In addition, the outer surface of the filter unit 400 is spaced apart from the inner surface of the main body 100 by a predetermined distance in order to secure a space in which raw water flows into the main body 100.

The filter unit 400 is formed of a plurality of filters 410, 430, and 450 arranged in concentric layers. The ceramic filter 410, the cement filter 430, and the carbon filter 450 are sequentially formed from the outermost layer to the inner side. Therefore, the incoming raw water is filtered while passing through the ceramic filter 410, the sediment filter 430, and the carbon filter 450.

First, the ceramic filter 410 is to add functionality to the water, it is preferable to use a mixture of germanium, monazite, tourmaline as a ceramic, and further mixed with silver nano.

More preferably, the ceramic filter 410 is manufactured by mixing 5 to 10 parts by weight of monazite, 2 to 5 parts by weight of tourmaline, and 0.05 to 0.1 parts by weight of silver nano with respect to 100 parts by weight of germanium.

Germanium is a porous mineral, which radiates abundantly far infrared energy to activate water to make clusters of water molecules small. Germanium may use natural germanium ores or pure GeO ₂ . Natural germanium ores contain various materials in addition to germanium, and using these germanium ores is much cheaper than using pure GeO ₂ .

In addition to the germanium, silica minerals such as diatomaceous earth and silica sand, clays of kaolinite, germanium, monazite, higerion, elvan, loess and the like can be used as the ceramic for emitting far infrared rays.

Monazite is a kind of photocatalytic material that generates antibacterial and anions. If it is less than 5 parts by weight, the effect is low.

Tourmaline generates an anion that is beneficial to the human body by generating a weak electric current. The effect is low at less than 2 parts by weight, and sinterability is lowered at more than 5 parts by weight. Examples of ceramics that emit such anions include tourmaline, guinea pigs, higerions, loess, elvan, gansumite, germanium, and the like. You can also use charcoal.

Silver nano and antimicrobial function to suppress the generation of microorganisms in the filter and serves to remove various odor components, if less than 0.05 parts by weight of the effect is insignificant and exceeds 0.1 parts by weight of the burden of manufacturing cost is too great.

The ceramic gemstones are pulverized by ball milling and then mixed by adding silver nanoparticles to be fired into a predetermined shape to prepare a ceramic filter 410. In addition, it may be molded into a ball shape and may be incorporated into the carbon filter 450 or the sediment filter 430 to be described later.

The sediment filter 430 removes even fine impurities of 1 micron size such as rust, debris, earth and sand, lime, and dust. The sediment filter 430 uses a polypropylene resin and can collect and remove many contaminants with a multi-fiber layer structure of fine fibers.

The carbon filter 450 is composed of carbon block activated carbon that removes odors and odors of heavy metals such as chlorine, carcinogens, and lead and cadmium in raw water and improves water taste.

The order of the carbon filter 450 and the sediment filter 430 may be different, and only one of the two filters 430 and 450 may be mounted and used.

In addition, a plurality of magnets 500 having an annular shape are installed at a predetermined interval in the hollow of the filter part 400. The water purified while passing through the filter unit 400 is magnetized while passing through the hollow passage in the center of the filter unit 400 in which the magnetic field is formed by the magnet 500. The magnet 500 may be formed in a rod shape, a rod shape or a plate shape as well as an annular shape, or may be embedded in the filter part 400 in a powder form.

In this way, the water molecules are rotated, stretched, and vibrated to become particulates and are activated by the far infrared rays emitted from the ceramic filter 410 and the magnetic force generated by the magnet 500. As a result, the cluster is kept in the original water having a small and high density.

The water molecules passing through the magnet 500 move more intensively than the water in the magnetic filtration between water molecules, and the negative ions of the water molecules are combined with iron in the tap water pipe 80 and the cations are released into the water. As the reduction potential of water decreases due to energy conversion, anions increase and two oxidized molten anions combine to be reduced to stable triiron tetraoxide (Fe ₃ O ₄ ). The ferric tetraoxide forms a coating on the inner surface of the pipe 80 to block the contact of water and iron to prevent oxidation of the pipe 80.

As described above, the water purified and magnetized while passing through the filter unit 400 and the magnet 500 may remove bacteria and microorganisms contained in the water by light irradiation of the light sterilization lamp 600.

Ultraviolet light, laser light, or the like can be used as light for sterilizing bacteria in water. In the illustrated example, the light sterilization lamp uses a fluorescent ultraviolet lamp that emits ultraviolet light.

The ultraviolet lamp 600 is inserted in the center of the connector 630 screwed into the through hole formed in the center of the first cap 200 is installed in the hollow of the center of the filter unit 400. In this case, a sealing member 650 is inserted between the connector 630 and the through hole of the first cap 200 to maintain airtightness. In addition, an O-ring 620 is installed at a portion where the terminal 610 of the ultraviolet lamp 600 contacts the center of the connector 630 to maintain airtightness.

The bactericidal effect by UV irradiation is effective for all species except mold. Since the sterilization effect of ultraviolet rays is 250 to 260 nm wavelength is most effective to vary depending on the wavelength of the ultraviolet ray, it is preferable to use the ultraviolet lamp 600 of the wavelength of 250 to 260 nm.

In this case, the photocatalyst material activated by the ultraviolet light emitted from the ultraviolet lamp 600 may be further provided around the ultraviolet lamp 600 in the form of a coating layer or a granular shape.

All the water supplied to the home can be purified by the water purifier 10 described above, so there is no need to provide a separate purification device in the home. The purifier 10 can fundamentally block harmful substances such as green water, various foreign substances, bacteria, viruses, and the like that enter the home.

On the other hand, the water pipe connection type purification apparatus 20 according to another embodiment of the present invention is shown in Figs.

3 is a perspective view of a water pipe connection type water purifier according to another embodiment of the present invention, and FIG. 4 is a partially cutaway perspective view of the lamp unit applied to FIG. 3.

3 and 4, the water purifier 20 includes a lamp unit 700 that sterilizes the water purified by the filter housing 95 described above by light irradiation, and an inside of the lamp unit 700. The transfer pipe 800 is further provided.

The lamp unit 700 has an ultraviolet lamp 730 as a light sterilizing lamp which is inserted in the center of the lamp housing 710 of the cylindrical housing is closed and hollow on both sides and inserted through the side of the lamp housing 710.

The transfer pipe 800 installed inside the lamp housing 710 is formed in a spiral shape surrounding the outer surface of the ultraviolet lamp 730. This is to extend the time for irradiating ultraviolet rays by allowing the water to flow while rotating about the ultraviolet lamp 730. In addition, the direction of the flow path formed by the transfer pipe 800 may be formed to be perpendicular to the longitudinal direction of the ultraviolet lamp 730 so that ultraviolet light may be incident at right angles to the water flowing through the transfer pipe 800. .

The feed pipe 800 and the purified water outlet pipe 310 of the filter housing 95 are connected to each other through a connecting pipe 90 installed in the middle.

The transfer pipe 800 is formed of a light transmissive material that can transmit ultraviolet light. It is preferable to use a transparent acrylic or quartz tube as the light transmitting material. The quartz tube has the best light transmittance, and the acrylic material has the advantage of manufacturing the lamp housing 710 and the transfer tube 800 integrally.

In addition, a photocatalyst coating layer (not shown) that is activated by the ultraviolet lamp 730 is formed on the inner surface of the transfer pipe 800.

Photocatalyst is a substance having strong redox ability by ultraviolet light, and can sterilize, antibacterial, decompose, antifouling, and deodorize adhesion substances and air in the surface by photocatalytic action. Examples of usable photocatalysts include ZnO, CdS, WO ₃ , TiO _2, and the like. Among them, ZnO and CdS have a disadvantage in that the catalyst itself is decomposed to light by absorbing light, and WO ₃ is efficient as a photocatalyst only for a specific material, and otherly, the efficiency is not as good as titanium dioxide.

Titanium dioxide, on the other hand, can be used semi-permanently because it does not change even when it receives light. In addition, titanium dioxide has much stronger oxidation power than that of the excitation electrons. The energy position of the hole is about +3 V at the hydrogen reference potential, which is much higher than that of 1.36 V of chlorine (Cl ₂ ) and 2.07 V of ozone (O ₃ ), and thus has strong sterilizing power and organic decomposition ability.

Therefore, it is preferable to use titanium dioxide (TiO ₂ ) as a photocatalyst.

Purified water primarily sterilized in the filter housing 95 as described above may be sterilized secondarily while passing through the lamp unit 700 to effectively sterilize bacteria or viruses.

In addition, by forming a photocatalyst coating layer on the inner surface of the transfer pipe 800, it is possible to maximize the sterilization effect by sterilizing bacteria or viruses contained in the water with ultraviolet light.

Although not shown, a light emitting diode that irradiates ultraviolet light with an ultraviolet lamp may be used. In this case, the light emitting diode is installed at the center of the lamp housing so that ultraviolet light can be irradiated to the transfer pipe. The light emitting diode has a small volume, which can reduce the size of the lamp housing, and there is almost no restriction on its position when the light emitting diode is installed.

5 and 6 illustrate a water pipe connection type water purification device according to another embodiment of the present invention.

5 and 6, the filter housing includes a main body 910 and a cap 930 screwed to a lower portion of the main body 910. The photocatalyst coating layer activated by ultraviolet light is formed on the inner surfaces of the body 910 and the cap 930. And O-rings 971 and 973 are installed to maintain confidentiality.

One side of the cap 930 is connected to the discharge tube of the meter 50 is formed with a raw water inlet tube 931 through which the raw water is introduced, and the other side of the cap 930 purified water discharge pipe for outflowing purified water ( 935 is formed.

Inside the filter housing, a filter unit 920 is built in, and raw water flowing through the raw water inlet pipe 931 is filtered while moving inward from the outer surface of the filter unit 920 and purified through the purified water outlet pipe 935. Water is supplied to the home. In this case, the lower portion of the filter unit 920 having the outlet is screwed with the purified water outlet pipe 935 so that the filtered water flows into the purified water outlet pipe 935.

In addition, a lamp unit 950 for irradiating ultraviolet light to remove the incoming raw water and the bacteria contained in the purified water is installed in the filter housing.

The lamp unit 950 may include a lamp housing 951 screwed on the lower portion of the cap 930 and a printed circuit board 955 installed inside the lamp housing 951 for easy detachability. A plurality of light emitting diodes 953 provided on the printed circuit board 955 and a connector 957 connected to the printed circuit board 955 to supply electricity to the printed circuit board 955 from the outside. And an O-ring 975 is installed between the lamp housing 950 and the cap 930 to maintain airtightness.

In the illustrated embodiment, a light emitting diode (LED) 953 is preferably used as a sterile lamp. The light emitting diode 953 has a low power consumption and a small volume, which is easy to install, and has a long life, high durability, and high impact resistance, so that the light emitting diode 953 can be safely used in a water purification device.

The upper surface of the lamp housing 951 is formed using a material that can transmit light such as transparent acrylic so that ultraviolet light emitted from the light emitting diode 953 can be irradiated to raw water. In addition, the purified water outflow pipe 935 formed inside the cap 930 is also formed of a transparent material so that the sterilized effect can be re-sterilized in the process of flowing out the filtered water from the filter unit.

Although not shown, the light emitting diode may be irradiated with ultraviolet light to the raw water flowing out or the purified water flowing out by molding the transparent molding material in the bottom of the cap or inside the purified water outlet pipe.
