Description
본 발명은 정수기에 설치되어 정수 저장탱크로 세균 등 미생물의 침입을 차단하는 에어벤트의 필터에 관한 것이다.The present invention relates to a filter of an air vent installed in the water purifier to block the invasion of microorganisms such as bacteria to the purified water storage tank.
일반적으로 정수 저장탱크 내에 채워진 물을 냉수 혹은 온수화하여 사용자로 하여금 필요에 따라 적절히 인출하여 음용할 수 있도록 구성된 정수기는 정수 저장탱크에서의 원활한 물의 공급을 유도하기 위해 워터가드의 일측에 소정의 에어벤트(air-vent)를 형성하고 있다.In general, a water purifier configured to cold or hot water filled in the purified water storage tank so that the user can withdraw and drink appropriately as needed, the predetermined water to one side of the water guard to induce a smooth supply of water from the purified water storage tank It is forming an air-vent.
상기 에어벤트는 정수 저장탱크와 정수기와의 긴밀한 결합으로 외부의 공기 유입이 차단되어 있는 상태에서 정수기의 냉수조에 물이 가득 채워져 있을 경우, 이와 연결되어 있는 정수 저장탱크와는 상호 압력의 차가 같게 되어 정수 저장탱크에서는 더 이상의 물이 공급될 수 없고, 물이 빠져 압력에 차이가 발생하게 되면 그 차이만큼 정수 저장탱크에서의 공급이 가능하게 된다. The air vent is in close coupling with the purified water storage tank and the water purifier, and when water is filled in the cold water tank of the water purifier in a state where external air inflow is blocked, the difference in mutual pressure is equal to that of the purified water storage tank connected thereto. No more water can be supplied from the purified water storage tank, and if the pressure is out due to the water dropping out, it is possible to supply the purified water storage tank by the difference.
이때 물이 빠지는 만큼 상대적으로 공기가 지속적으로 유입되어야만 정수 저장탱크 내의 부피 변화가 유발되지 않아 체적 축소에 따른 정수 저장탱크의 파손이 나 균열이 방지되고 누수 역시 방지할 수 있는 것이다. 따라서 상기 에어벤트는 외부로부터의 공기유입이 자유로울 수 있도록 워터가드의 소정 위치에 작은 통공 형식으로 제공된다. At this time, as the water drains, air must be continuously flowed in order to prevent volume change in the purified water storage tank, thereby preventing damage or cracking of the purified water storage tank due to volume reduction, and preventing leakage. Therefore, the air vent is provided in the form of a small through-hole at a predetermined position of the water guard so that the air inflow from the outside can be free.
한편, 상기 통공을 통해 정수 저장탱크 내로 이물질과 유해물의 투입을 방지하기 위해서 에어벤트 필터로서 상기 통공에 부직포나 스펀지 등이 완전 밀폐 방식으로 내삽된 에어벤트가 적용되고 있으며, 이와 같은 부직포 등과 같은 에어벤트 필터에 의해 공기만을 통과시키고 먼지, 개미 등의 벌레와 같은 이물질의 유입을 하는 구조를 갖는다.On the other hand, in order to prevent the introduction of foreign substances and harmful substances into the purified water storage tank through the air through the air vent is a non-woven fabric or sponge is inserted into the air vent in a completely sealed manner, such as non-woven fabric such as air The vent filter allows only air to pass through and introduces foreign substances such as dust, ants, and insects.
그러나, 상기와 같은 종래의 정수기 에어벤트에 적용되던 부직포나 스펀지를 사용한 에어벤트 필터는 다소 입자가 큰 이물질에 대한 정수 저장탱크 내로의 유입을 차단하는 데는 효과적이지만, 매우 작은 사이즈의 일반 세균 등에 대하여는 충분한 필터효과를 제공한다고는 볼 수 없다. 더욱이 위생에 대한 소비자의 관심이 한층 고조된 요즈음에 있어서는 육안으로 식별할 수 없는 일반 세균에 대한 침투 방지 기능은 더욱 필요하다고 할 것이다.However, the air vent filter using the nonwoven fabric or sponge used in the conventional water purifier air vent as described above is effective to block the inflow into the water storage tank for the somewhat large foreign substances, but for the very small size of ordinary bacteria and the like. It does not seem to provide enough filter effect. Moreover, in recent years, when consumers' interest in hygiene is heightened, it is more necessary to prevent invasion of general bacteria which cannot be visually identified.
본 발명은 상기와 같은 종래의 에어벤트 필터의 문제점을 해결하기 위한 것으로서, 이물질은 물론, 일반세균이 에어벤트를 통하여 정수 저장탱크 내로 침입하는 것을 차단하는 것을 목적으로 한다.The present invention is to solve the problems of the conventional air vent filter as described above, it aims to block foreign matter, as well as general bacteria infiltrate into the purified water storage tank through the air vent.
상기와 같은 목적을 달성하기 위하여, 본 발명은In order to achieve the above object, the present invention
제1 구현예로서, 정수기의 에어벤트(airvent)에 설치되는 에어벤트 필터로서, 상기 필터가 ASHRAE(American Society of Heating, Refrigerating and Air Conditioning Engineers) STANDARD 52-2-1999 규정에 따른 성능이 0.3㎛ 입자 제거율이 60% 이상인 HEPA(High Efficient Particulate Arrestance) 타입 필터임을 특징으로 하는 정수기용 항균 에어벤트 필터, 및 In a first embodiment, an air vent filter installed in an air vent of a water purifier, the filter having a performance in accordance with American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) STANDARD 52-2-1999, 0.3 μm Antibacterial air vent filter for water purifier, characterized in that the particle removal rate is 60% or more HEPA (High Efficient Particulate Arrestance) type filter, and
제2 구현예로서, 상기 HEPA 타입 필터가 에어벤트 필터로 설치된 에어벤트를 포함하는 정수기를 제공한다.In a second embodiment, the HEPA type filter provides a water purifier comprising an air vent installed as an air vent filter.
본 발명의 에어벤트 필터를 설치함으로써, 에어벤트를 통하여 미세 입자나 곤충 등은 물론, 일반 세균까지 정수 저장탱크로 침투하는 것을 방지할 수 있다.By providing the air vent filter of the present invention, it is possible to prevent infiltration of fine particles, insects, and the like into general water storage tanks through the air vent.
본 발명에 있어서, 정수기의 에어벤트(airvent)에는 에어벤트 필터로서 HEPA(High Efficient Particulate Arrestance) 타입 필터가 설치된다. In the present invention, a HEPA (High Efficient Particulate Arrestance) type filter is installed in the air vent of the water purifier.
일반적으로 HEPA 필터는 전자제품 제조의 클린룸, 병원의 수술실, 제약회사 등에서 오염 공기의 정화를 위해 널리 사용되어, 공기청정기, 에어콘, 진공청소기, 자동차, 고층건물의 공조기 등에서 HEPA 필터가 장착되어 사용되었다. 그러나, 정수기의 에어벤트에 HEPA 필터가 적용된 경우는 없었다.In general, HEPA filters are widely used for the purification of contaminated air in clean rooms of electronics manufacturing, operating rooms of hospitals, pharmaceutical companies, etc., and HEPA filters are installed in air cleaners, air conditioners, vacuum cleaners, automobiles, and air conditioners in high-rise buildings. It became. However, no HEPA filter was applied to the air vent of the water purifier.
HEPA 필터에 대하여는 국내에서는 아직 HEPA 필터의 성능에 대하여 규정하고 있지 않으며, 미국 ASHRAE(American Society of Heating, Refrigerating and Air Conditioning Engineering, 냉동공조 협회) STANDARD 52-2-1999에서 규정하는 성능 기준을 참고로 HEPA 필터를 정의할 수 있다.The HEPA filter is not yet defined in Korea in terms of the performance of the HEPA filter, and is based on the performance standards specified in the American Society of Heating, Refrigerating and Air Conditioning Engineering (ASHRAE) STANDARD 52-2-1999. HEPA filters can be defined.
상기 기준에 따르면, HEPA 필터에 대하여 입경이 0.3㎛인 입자상 물질(예를 들어, 먼지, 박테리아, 바이러스 등)을 99.97% 이상 포집 가능한 필터로 규정하고 있다. 그러나, 본 발명에서는 입경이 0.3㎛인 입자상 물질을 60% 이상인 범위 내에서 포집 가능한 것을 사용하는 것이 바람직한데, 이하에서는, 이러한 필터를 편의상 'HEPA 타입 필터'라고 칭한다.According to the above criteria, the HEPA filter is defined as a filter capable of collecting 99.97% or more of particulate matter (eg, dust, bacteria, viruses, etc.) having a particle size of 0.3 µm. However, in the present invention, it is preferable to use a particulate material having a particle size of 0.3 μm within a range of 60% or more. Hereinafter, such a filter is referred to as an “HEPA type filter” for convenience.
상기 입경이 0.3㎛인 입자상 물질을 60% 이상 포집 가능한 HEPA 타입 필터를 사용함으로써 일반 세균이 정수 저장탱크 내로 침투하는 것을 효과적으로 억제할 수 있으며, 그 포집능이 우수할수록 일반 세균의 침투 차단 효과 역시 우수하다.By using a HEPA type filter capable of collecting 60% or more of the particulate matter having a particle diameter of 0.3 μm, it is possible to effectively inhibit the penetration of general bacteria into the purified water storage tank, and the better the capturing ability, the better the blocking effect of general bacteria. .
상기와 같은 성능을 갖는 HEPA 타입 필터라면 어떠한 필터라도 사용할 수 있는 것으로서, 특별히 한정하지 않는다. 따라서, 일반적으로 HEPA 필터를 제조하는데 사용되는 재질의 것을 사용할 수 있으며, 대표적으로는 글라스 파이버를 들 수 있다.Any filter can be used as long as it is a HEPA type filter having the above-described performance, and is not particularly limited. Therefore, generally, a material made of a material used to manufacture a HEPA filter can be used, and glass fiber is representatively used.
이하, 본 발명을 아래의 실시예를 들어 더욱 구체적으로 설명한다. 그러나, 본 발명은 이하의 실시예로 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the present invention is not limited to the following examples.
실시예Example
실시예 1Example 1
정수기의 에어벤트 필터로서, 기존에 사용되던 부직포를 적용한 경우(기존 구성), 3㎛ 입자 제거율이 65%, 85% 및 99.5%인 HEPA(또는 HEPA 타입) 필터를 적용한 후, 정수기 내의 물의 오염정도를 정수 저장탱크에서의 일반세균 증식 정도를 측정하여 비교하였다. 코크에서의 추출 유량을 측정하였다. 측정한 결과를 도 1에 나타내었다.As an air vent filter of a water purifier, when a conventional nonwoven fabric is applied (conventional configuration), the degree of contamination of water in the water purifier is applied after applying a HEPA (or HEPA type) filter having 3 μm particle removal rates of 65%, 85%, and 99.5%. Was compared by measuring the general bacterial growth in the purified water storage tank. The extraction flow rate in the coke was measured. The measured result is shown in FIG.
본 발명에 따른 HEPA 필터를 적용한 경우에는 기존의 부직포를 적용한 경우에 비하여 정수 저장탱크 내에 존재하는 일반세균의 양이 현저하게 감소하였음을 확인할 수 있다.When the HEPA filter according to the present invention is applied, it can be seen that the amount of general bacteria present in the purified water storage tank is significantly reduced compared to the case of applying the conventional nonwoven fabric.
도 1은 실시예 1에 따라 각종 필터를 에어벤트에 적용한 경우의 일반세균 발생 억제 효과에 대한 결과를 나타내는 그래프이다.1 is a graph showing the results of the general bacteria generation inhibitory effect when various filters are applied to an air vent according to Example 1. FIG.
