Description
본 고안은 정수용 살균 및 항균 은 필터에 관한 것으로서, 보다 상세하게는 나노 크기의 은 입자로 코팅 처리된 야자 활성탄과 99.99% 순도의 순은(Silver)을 소재로 하여 만들어진 은 폼을 동시에 사용하여 정수기를 통과하는 물을 효과적으로 살균 처리하고, 아울러 정수 완료된 물을 저장하는 저장탱크 안에서도 오염된 세균을 사후 살균할 수 있도록 구성된 기능성 필터에 관한 것이다.The present invention relates to a sterile and antimicrobial silver filter for water purification, more specifically, a water purifier using a silver form made of palm activated carbon coated with nano-sized silver particles and 99.99% pure silver. The present invention relates to a functional filter configured to effectively sterilize water passing through and further sterilize contaminated bacteria even in a storage tank storing purified water.
종래의 정수기용 항균필터로는 은 분말이 미량 혼합된 활성탄으로 구성된 실버 카본 필터나, 은 분말을 혼합하여 만든 은 세라믹 필터 또는 은 폼 단독으로 구성된 은 폼 필터 등이 있다. 이 외에 항균 또는 살균 목적으로 UV 살균기 및 멤브레인 필터, 항균 세라믹 볼 등이 정수기에 사용되기도 한다.Conventional antibacterial filters for water purifiers include silver carbon filters composed of activated carbon in which trace amounts of silver powder are mixed, silver ceramic filters made by mixing silver powders, or silver foam filters composed of silver foams alone. In addition, UV sterilizers, membrane filters, and antibacterial ceramic balls are used in water purifiers for antibacterial or sterilization purposes.
전술한 실버 카본 필터는 은 분말이 활성탄에 미량 혼합되어 있는 필터로서 은 분말 사용량이 미량인데다 은 분말이 필터 외부로 지속적으로 용출되어 소진되기 때문에 항균능력이 미약하고, 시간이 경과 함에 따라 미약한 항균 효능조차 발휘되지 못하는 문제점을 지니고 있으며, 은 세라믹 필터는 전량 외국 수입 제품으로 가격이 고가인 관계로 국내 정수기에는 거의 사용되지 않고 있는 실정이다. 이들 실버 카본 필터와 은 세라믹 필터는 정수가 완료된 물에 대해서는 전혀 항균 기능을 발휘하지 못한다는 한계점을 공통으로 지니고 있다. The silver carbon filter described above is a filter in which a small amount of silver powder is mixed with activated carbon, and a small amount of silver powder is used, and since the silver powder is continuously eluted and exhausted to the outside of the filter, the antimicrobial ability is weak. There is a problem that even the efficacy is not exhibited, and the silver ceramic filters are all imported from foreign countries, and the price is high, so they are rarely used in domestic water purifiers. These silver carbon filters and silver ceramic filters have a common limitation that they do not exhibit antibacterial function against purified water.
한편 은 폼 필터는 순간적인 살균 효능보다 은 폼에서 용출된 미량의 은 입자가 정수 완료된 물을 저장하는 저장탱크 내에 물과 같이 유입되어 들어감으로써 사후 항균 효능만을 발휘하는 한계점을 지니고 있다.On the other hand, the silver foam filter has a limit of exerting antimicrobial efficacy only after a small amount of silver particles eluted from the silver foam flows into the storage tank storing purified water rather than instantaneous sterilization efficacy.
이 외에 UV 살균기 및 항균 세라믹 볼은 보조적인 수단에 불과하여 미생물을 제어하는데 비효율적이며, 멤브레인 필터는 정수 과정에서 미생물을 확실하게 제거하기는 하나 정수가 완료된 물에 대해서는 어떠한 항균 기능도 발휘하지 못하는 문제점을 지니고 있다. In addition, UV sterilizers and antibacterial ceramic balls are only auxiliary means, and they are inefficient in controlling microorganisms. Membrane filters reliably remove microorganisms during the water purification process, but do not exhibit any antibacterial function against the purified water. It has
이와 같은 여건으로 정수기를 제조 또는 판매하는 업체에서는 정수기의 불완전한 항균 및 살균 기능을 보완하기 위하여 나름대로 고심하고 있으나, 아직까지 기능 및 경제성 측면에서 효과적인 필터를 찾아내지 못한 상태이다.Under these circumstances, companies that manufacture or sell water purifiers are struggling to compensate for the incomplete antibacterial and sterilizing functions of the water purifier, but have not yet found effective filters in terms of function and economics.
본 고안은 전술한 바와 같은 문제점들을 해결하기 위하여 제안된 것으로서, 본 고안은 정수 과정에서 물속의 미생물을 흡착, 살균, 제거할 뿐만 아니라 정수된 물이 저장되는 저장탱크가 미생물에 오염되어 있는 상황을 고려하여 저장탱크 내에서도 지속적으로 살균 효능을 발휘할 수 있도록 하는 새로운 구성의 필터를 제공함을 목적으로 한 것이다.The present invention is proposed to solve the problems described above, the present invention not only adsorbs, sterilizes, and removes the microorganisms in the water during the purification process, but also the situation that the storage tank in which purified water is stored is contaminated with microorganisms. It is an object of the present invention to provide a filter of a new configuration that can continuously exhibit sterilization efficacy even in a storage tank.
본 고안의 제안시 고려하여야 할 핵심 과제는 물속의 미생물을 필터 내에서 순간적으로 흡착하여 살균 및 제거하는 역할을 하는 은 코팅 야자 활성탄(12)에 흡착, 코팅된 은 입자가 필터 외부로 용출되지 않고 활성탄에 반영구적으로 고착되어 있으면서 지속적으로 살균 기능을 발휘하도록 하는 것이다. The core task to be considered in the proposal of the present invention is that the silver particles adsorbed and coated on the silver-coated palm activated carbon 12, which serves to instantly adsorb and sterilize and remove microorganisms in water, are not eluted to the outside of the filter. It is to be permanently attached to activated carbon while maintaining its sterilization function.
이를 위하여 본 고안에서는 1~10 나노 크기의 미세한 은 입자를 무전극 도금 방식으로 정수용 야자 활성탄에 반영구적으로 흡착, 코팅시켜 은 입자가 활성탄에서 반영구적으로 떨어지지 않도록 특별히 고안한 별도의 은 코팅 야자 활성탄을 사용하도록 하였다. 기존의 정수기에 널리 사용되는 시중의 항균용 실버 카본은 미량의 미세한 은 분말이 활성탄과 단순히 혼합되어 있는 상태로 섞여있기 때문에 정수 과정에서 물과 함께 은이 용출되어 소진될 뿐만 아니라, 은 함유량도 미량에 불과하여 항균 및 살균효과가 매우 미약하다는 문제점을 지니고 있어 본 고안이 달성하고자 하는 목적에 적합하지 않다. 또한, 이들 실버 카본은 은이 모두 용출되어 없어지게 되면 항균 및 살균 기능을 하는 것이 아니라, 오히려 세균 번식의 온상이 되어 정수기를 통과한 물이 세균 등 미생물에 더 오염되게 하는 문제점을 나타내게 된다.To this end, in the present design, a special silver-coated palm activated carbon specially designed to prevent semi-permanent fall of the silver particles from the activated carbon is adsorbed and coated semi-permanently on the purified activated carbon activated carbon by electroless plating. It was made. Commercially available antimicrobial silver carbon, which is widely used in water purifiers, contains a small amount of fine silver powder simply mixed with activated carbon. Therefore, silver is eluted and consumed together with water during the water purification process. Only because it has a problem that the antimicrobial and bactericidal effect is very weak, this invention is not suitable for the purpose to achieve. In addition, these silver carbons do not function as antibacterial and sterilization when all of the silver is eluted and disappeared, but rather becomes a hotbed of bacterial propagation, thus showing a problem that water passing through the water purifier is more contaminated with microorganisms such as bacteria.
본 고안은 전술한 목적을 달성하기 위하여 나노 크기의 미세한 은 입자로 코팅 처리된 야자 활성탄과 은 폼을 같이 사용하여 구성된 필터를 제공하고자 한다. The present invention is to provide a filter composed of a combination of palm activated carbon and silver foam coated with nano-sized fine silver particles in order to achieve the above object.
이하 첨부 도면을 참고로 하여 본 고안에 따른 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안의 실시예에 따른 정수용 살균 및 항균 은 필터의 구성도이다.1 is a block diagram of the sterilization and antibacterial silver filter for water purification according to an embodiment of the present invention.
도 1에 도시된 바와 같이 본 고안의 정수용 살균 및 항균 은 필터는 필터 몸체(41) 내부의 출수부인 토출구(52) 측에 은 폼(11)을 먼저 구비하고, 구비된 은 폼(11)의 유입구(52) 측 상단에 부직포(31)를 구비하며, 부직포(31) 상단에는 고정 링(21)을 구비하여 은 폼(11)이 고착되도록 하였다. 이와 같이 구비된 고정 링(21) 상단에 나노 크기의 은 입자로 흡착, 코팅 처리된 야자 활성탄(12)을 채우고, 은 코팅 야자 활성탄(12) 상단에 부직포(32)와 고정 링(22)을 구비한 후 필터 덮개(42)를 씌운 다음 필터 몸체(41)와 접착하여 완성한다.As shown in FIG. 1, the sterilizing and antimicrobial silver filter for water purification of the present invention is first provided with a silver foam 11 at a discharge port 52 side, which is an outlet portion inside the filter body 41, and has a The non-woven fabric 31 is provided at the upper end of the inlet 52, and the fixing ring 21 is provided at the upper end of the nonwoven fabric 31 to fix the silver foam 11. Adsorption and coating of the activated activated carbon (12) on the top of the fixed ring 21 provided with nano-sized silver particles, and the non-woven fabric 32 and the fixed ring 22 on the top of the silver coated palm activated carbon 12 After providing the filter cover 42 is completed by bonding with the filter body 41.
이와 같은 본 고안을 실시함에 있어서 상술한 일 실시예의 구성은 본 고안을 구성하는 바람직한 일 실시예로 제시된 것이지 반드시 이에 국한하는 것은 아니다.In the implementation of the present invention as described above, the configuration of the above-described embodiment is presented as a preferred embodiment of the present invention, but is not necessarily limited thereto.
예를 들어 필터 몸체 및 배관 연결구 등의 형태는 본 고안을 적용하게 될 정수기가 요구하는 사양에 따라 임의로 다양하게 변경, 실시할 수 있는 것이다. For example, the shape of the filter body and the pipe connection, etc. can be arbitrarily variously changed and implemented according to the specifications required by the water purifier to which the present invention is applied.
본 고안의 정수용 살균 및 항균 은 필터를 정수기에 설치할 때는 반드시 물이 유입구(51)로부터 토출구(52) 방향으로 흐르도록 설치하여야 한다. 이는 본 고안의 필터에 유입된 물이 은 코팅 야자 활성탄(12)을 거치면서 1차로 물속의 세균 등 미생물이 은 코팅 야자 활성탄(12)에 흡착, 살균, 제거되도록 하고, 다음에 2차로 은 폼(11)을 거치면서 나노 크기의 미세한 은 입자가 미량 용출되어 정수된 물과 같이 저장탱크로 유입되도록 하여 저장탱크 내에 존재하는 미생물까지 제거하도록 하기 위함이다. 설치 방향을 거꾸로 하게 되면 은 폼(11)에서 용출된 은 입자가 은 코팅 야자 활성탄(12)을 통과하면서 활성탄에 모두 흡착, 제거되기 때문에 본 고안이 이루고자 하는 목적을 달성할 수 없게 된다.When the sterilization and antimicrobial silver filter for water purification of the present invention is installed in the water purifier, it must be installed so that water flows from the inlet 51 to the outlet 52. This allows water introduced into the filter of the present invention to pass through the silver-coated palm activated carbon 12 so that microorganisms such as bacteria in the water are first adsorbed, sterilized and removed from the silver-coated palm activated carbon 12, and then secondly, silver foam. This is to remove the microorganisms present in the storage tank by passing a small amount of nano-sized fine silver particles through (11) to flow into the storage tank, such as purified water. When the installation direction is reversed, the silver particles eluted from the silver foam 11 are adsorbed and removed from the activated carbon while passing through the silver-coated palm activated carbon 12, thereby failing to achieve the object of the present invention.
또한, 본 고안을 정수기에 설치할 때에는 정수기에 기 사용되고 있는 다양한 필터(세디 필터, 프리 카본 필터 등)들을 먼저 연결, 설치하고, 맨 마지막 단계에 본 고안의 필터를 연결, 설치하여야 본 고안이 이루고자 하는 소기의 목적을 달성할 수 있다.In addition, when the present invention is installed in the water purifier, various filters (Cedi filter, pre-carbon filter, etc.) used in the water purifier are first connected and installed, and the filter of the present invention is connected and installed at the last stage to achieve the present invention. The desired purpose can be achieved.
이상에서 설명한 바와 같은 본 고안에 의하면, 본 고안의 정수용 살균 및 항균 은 필터를 정수기의 마지막 단계에 설치하여 사용할 경우 물속의 세균 등 미생물을 즉시 살균, 제거할 뿐만 아니라, 오염된 저장탱크로 유입된 물까지 사후에 살균 처리하도록 하여 위생적이며 안전한 물을 항시 안심하고 사용할 수 있도록 하는 장점이 있다.According to the present invention as described above, when the sterilization and antibacterial silver filter for water purification of the present invention is installed and used in the last stage of the water purifier, the microorganisms such as bacteria in the water are immediately sterilized and removed, There is an advantage in that it is possible to safely use hygienic and safe water at all times by performing sterilization treatment after the water.
