Description
본 발명은 정수기 본체에 내장되어 물을 냉각할 수 있도록 하는 정수기의 냉각장치에 관한 것으로, 더 자세하게는 냉각통의 둘레에 냉매가 순환되는 냉각코일을 감은 것에 있어서 냉각통의 내부로 유입되는 물을 보다 효과적으로 냉각시킬 수 있도록 한 것에 관한 것이다.The present invention relates to a cooling device for a water purifier, which is built in the water purifier main body to cool water, and more particularly, in the case of winding a cooling coil in which a refrigerant is circulated around the cooling tank, It is about making it possible to cool more effectively.
일반적으로 마실 물을 맑게 정화할 수 있도록 하는 정수기는 그 형태에 따라 수도꼭지에 직접 연결하여 사용하는 수도꼭지 부착형과 유리단지에 물을 받아 자연낙하과정에서 정수하는 탁상형(비배관형)으로 나눌 수 있으며, 정수방식에 따라 수도직결식, 자연여과식, 이온교환수지식, 증류식, 역삼투압식, 이온수기식 등으로 나눌 수 있는 바, 대체로 자연여과식과 역삼투압식, 수도직결식이 많이 쓰이고 있다.In general, the water purifier to clean the drinking water can be divided into the faucet attachment type used by directly connecting to the faucet and the table type (non-piping type) that receives water from the glass complex and purifies it during the natural dropping process. According to water purification method, it can be divided into water direct connection type, natural filtration type, ion exchange resin type, distillation type, reverse osmosis type, ion number type type, etc.
상기에서 수도직결식은 수도꼭지에 정수기를 직접 연결하여 물이 마이크로필터 및 은활성탄필터를 거치면서 불순물이 제거되도록 하는 방식으로, 한 번에 많은 물을 정수하여야 하므로 필터의 구멍이 커져 바이러스, 중금속, 발암물질(트리할로메탄), 화학오염물질, 미세물질 등의 제거가 어렵고 필터를 자주 갈아주어야 하는 단점이 있다.In the above method, the direct connection of the water purifier is directly connected to the faucet so that water can be removed while passing through the micro filter and the silver activated carbon filter. It is difficult to remove substances (trihalomethane), chemical contaminants, and fine substances, and has the disadvantage of frequently changing the filter.
그리고 역삼투압식은 각종 불순물이 섞여있는 물에 압력을 주어 물이 반투막을 통과할 때 불순물은 걸러주고 순수한 물과 용존산소 및 미량의 미네랄만을 통과시켜 정수하는 방식으로, 오염물질 뿐 아니라 미네랄까지 제거한다는 점과 수압이 약한 곳에서 워터펌프를 설치해야하는 단점이 있다.The reverse osmosis system applies pressure to water containing various impurities and filters water as it passes through the semi-permeable membrane and removes impurities as well as pollutants by purifying only pure water, dissolved oxygen and trace minerals. There is a disadvantage in that the water pump must be installed at a weak point and water pressure.
한편 이온교환수지식은 첨단소재인 이온교환수지를 이용하여 센물을 단물로 바꾸는 장치로서 중금속을 걸러내므로 수도관이 오래된 지역에서 사용하면 좋지만 발암물질인 트리할로메탄을 제거할 수 없는 단점이 있으며, 이온수기식은 이온수기에 정수기능을 부착하여 정수된 물을 알칼리성과 산성으로 분리시키는 것을 목적으로 하는 것으로, 주로 의료용으로 사용된다.On the other hand, the ion exchange resin is a device that converts hard water into a single water using ion exchange resin, which is a high-tech material. The ionizer type is to attach purified water to the ionizer to separate purified water into alkaline and acid, and is mainly used for medical purposes.
본 발명은 상기 여과방식을 불문하고 상수도에서 공급되는 물을 침전필터, 살균필터, 이온필터, 카본필터, 멤브레인필터, 세라믹필터 등의 다수의 필터(filter)를 통해 정화하는 정수기에 관계하는 것인 바, 이와 같은 정수기는 대개 본체의 내부에 다수의 필터가 설치되고, 본체의 전면 중앙부에 정수된 물을 외부로 배출할 수 있도록 하는 배출콕크가 설치되는 것이 보통이다.The present invention relates to a water purifier for purifying water supplied from a tap water regardless of the filtration method through a plurality of filters such as a precipitation filter, a sterilization filter, an ion filter, a carbon filter, a membrane filter, a ceramic filter, and the like. Bars such as water purifiers are usually provided with a plurality of filters in the interior of the main body, the discharge cock is usually installed in the front center of the main body to discharge the purified water to the outside.
아울러 정수기 본체에는 냉각장치와 가열장치가 설치되어 찬물과 더운물을 선택적으로 공급할 수 있도록 하는 것이 보통인 바, 찬물을 공급할 수 있도록 하는 냉각장치는 대개 냉각통의 둘레에 냉매가 순환되는 냉각코일을 설치한 형태의 것이 주로 사용되고 있다.In addition, the water purifier main body is provided with a cooling device and a heating device to selectively supply cold and hot water, and a cooling device for supplying cold water is usually provided with a cooling coil in which a refrigerant is circulated around the cooling cylinder. One type is mainly used.
그러나 종래의 냉각장치는 일정 용량의 냉각통의 둘레에 냉각코일을 설치한 비교적 단순한 형태로 되어 있었기 때문에 냉각통에 저장되는 물을 냉각하기 위해 일정시간이 필요하게 되어 짧은 시간동안에 많은 양의 찬물을 공급할 수 없게 되는 문제가 있었다.However, since a conventional cooling device has a relatively simple form in which a cooling coil is installed around a cooling cylinder of a predetermined capacity, a certain amount of time is required to cool the water stored in the cooling cylinder. There was a problem of being unable to supply.
즉, 종래의 냉각장치가 장착된 정수기에서 찬물을 인출하는 경우 초기에는 냉각통에 차가워진 상태로 저장된 물이 공급되지만 냉각통에 저장된 찬물이 모두 인출된 후에는 미처 냉각되지 못한 미지근한 물이 공급되는 등 시간이 지날수록 배출수온이 높아지게 되는 문제가 있었다.In other words, when cold water is drawn out from a water purifier equipped with a conventional cooling device, initially stored water is supplied to a cooling container, but lukewarm water that has not been cooled is supplied after all cold water stored in the cooling container is drawn out. There was a problem that the discharge water temperature is higher as time passes.
이에 냉각통의 내부 중앙에 냉매순환코일을 설치하고, 그 둘레에 흡열판과나선판이 마련된 흡열실린더를 설치하여 냉각효율을 향상시킬 수 있도록 한 냉각장치가 제안(대한민국 공개특허공보 공개번호 1998-53406호)된 바 있으나 이 종래의 다른 냉각장치는 냉각통의 내부에 냉매순환코일을 비롯한 각종 구조물이 장착되어 냉각통의 저수용량이 크게 줄어들게 될 뿐 아니라 넓은 표면적의 냉각통 외주면 전체가 외부 공기에 노출되므로 오히려 전체적인 냉각능력이 저하되는 문제가 있는 것이었다.In this regard, a cooling device is provided in which a refrigerant circulation coil is installed at the inner center of the cooling cylinder, and an endothermic cylinder provided with a heat absorbing plate and a spiral plate is installed around the cooling tube to improve the cooling efficiency. However, this conventional other cooling device is equipped with various structures including refrigerant circulation coils inside the cooling cylinder, which greatly reduces the low capacity of the cooling cylinder and exposes the entire outer surface of the cooling cylinder to the outside air. Rather, there was a problem that the overall cooling capacity is lowered.
본 발명은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 냉각통의 저수용량을 감소시키지 않고서도 냉각효율을 향상시킬 수 있도록 하는 정수기의 냉각장치를 제공하는 데에 있는 것이다.The present invention has been devised in view of the above-described conventional situation, and an object thereof is to provide a cooling device for a water purifier capable of improving the cooling efficiency without reducing the low capacity of the cooling cylinder.
