본 고안은 냉이온정수기용 냉각조에 관한 것으로, 특히 밀폐형의 냉각조본체내에 원통형으로 권취한 정수순환관과 이러한 정수순환관의 내측에 동심원상이 되게 원통형으로 권취한 냉매코일관을 배치하고 이들 정수순환관과 냉매코일관이 배치된 냉각조본체내에 부동액을 채우고 이러한 부동액이 냉각조본체내에서 자체순환할 수 있도록 하여 냉매코일관을 순환하는 냉매와 정수순환관을 순환하는 정수 사이에 부동액을 매개로 한 열교환이 이루어질 수 있도록 하여 정수순환관을 순환하 는 정수를 냉각시킬 수 있도록 한 냉이온정수기용 냉각조에 관한 것이다.The present invention relates to a cooling tank for a cold ion water purifier, and in particular, a cylindrically wound purified water circulation pipe and a refrigerant coil pipe wound in a cylindrical shape concentrically in the interior of the purified water circulation pipe are arranged in these sealed circulation tanks. The antifreeze is filled in the cooling tank main body in which the pipe and the refrigerant coil pipe are arranged, and the antifreeze is allowed to self-circulate in the cooling tank main body. The present invention relates to a cooling tank for a cold ion water purifier capable of cooling a purified water circulating in a purified water circulating pipe by allowing a heat exchange to occur.

종래, 예를 들어 냉정수기의 경우에 있어서, 냉각조내에는 냉각회로부터 연장된 냉매코일관이 원통형의 형태로 권취되어 배치되고 냉각조의 내부에는 정수필터를 통하여 정수된 물이 유입되고 냉매코일관에 의하여 냉각된 후에 유출될 수 있게 되어 있다. 즉, 종래의 냉정수기에 있어서, 정수된 물이 냉매코일관에 직접 접촉하여 냉매코일관을 순환하는 냉매와 열교환이 이루어져 냉각될 수 있게 되어 있다. 이와 같이, 정수된 물이 냉매코일관에 직접 접촉하여 냉각되는 경우, 냉매코일관의 표면이 다른 부위 보다 더욱 냉각되므로 결빙되어 정수된 물의 냉각효율을 떨어뜨리는 결점이 있다.Conventionally, for example, in the case of a cold water purifier, a refrigerant coil pipe extending from a cooling ash is disposed in a cylindrical shape in a cooling tank, and purified water flows into the cooling tank through a purified water filter, and a refrigerant coil pipe is introduced. After cooling, it can flow out. That is, in the conventional cold water purifier, the purified water is directly contacted with the refrigerant coil pipe to exchange heat with the refrigerant circulating through the refrigerant coil pipe, thereby allowing cooling. As such, when the purified water is directly contacted and cooled by the refrigerant coil pipe, the surface of the refrigerant coil pipe is cooled more than other portions, so that the purified water freezes, thereby reducing the cooling efficiency of the purified water.

본 고안에 있어서는 종래의 이와 같은 점을 감안하여 안출한 것으로, 정수된 물이 냉매코일관에 직접 접촉하지 않고 정수순환관을 통하여 순환되도록 하며 부동액을 매개로 하여 냉매코일관을 순환하는 냉매와 열교환이 이루어져 냉각될 수 있도록 함으로서 냉매코일관의 표면이 결빙되어 냉각효과를 저하시키지 않도록 한 냉이온정수기용 냉각조를 제공하는데 그 목적이 있다.In the present invention, in view of the above-mentioned point in the prior art, the purified water is circulated through the purified water circulation pipe without directly contacting the refrigerant coil pipe and the heat exchange with the refrigerant circulating the refrigerant coil pipe through the antifreeze medium. The purpose of the present invention is to provide a cooling tank for a cold ion water purifier in which the surface of the refrigerant coil pipe freezes so as not to deteriorate the cooling effect.
