일반적으로 냉장고는 냉각 사이클을 이용하여 고내실의 공기를 냉각시켜 고내실에 저장된 식품 등이 변질되지 않고 장기간 보존되도록 하는 것으로, 냉장고는 압축기(compressor)의 작동에 의해 고온.고압으로 압축된 냉매가스(refrigerant gas)를 응축기(condenser)에서 액화시켜 액체 상태로 변화시킨 후에, 팽창밸브(expansion valve)를 거쳐 감압시키고 증발기(evaporator)에서 증발시킴으로써 냉매의 증발열에 의해 외기로부터 열을 빼앗아 냉각작용을 하는 장치이다.In general, the refrigerator cools the air in the chamber by using a cooling cycle so that foods stored in the chamber are stored for a long time without deterioration. The refrigerator is a refrigerant gas compressed at high temperature and pressure by the operation of a compressor. (refrigerant gas) is liquefied in a condenser (condenser) into a liquid state, and then decompressed through an expansion valve (expansion valve) and evaporator (evaporator) by taking the heat from the outside air by the heat of evaporation of the refrigerant by evaporation (cooling action) Device.

종래의 냉장고는 도 1에 도시된 바와 같이 외관을 이루며 내부에 냉장실(12)과 냉동실(11)이 구획벽(13)에 의하여 구획되어 마련된 본체(10)를 구비하며, 본체(10)의 정면에는 냉장실(12)과 냉동실(11)을 개폐하는 냉장실도어(15)와 냉동실도어(14)가 설치된다.Conventional refrigerators have a main body 10 formed in the exterior as shown in FIG. 1 and having a refrigerating chamber 12 and a freezing chamber 11 partitioned by partition walls 13 therein, and having a front surface of the main body 10. The refrigerator compartment door 15 and the freezer compartment door 14 which open and close the refrigerating compartment 12 and the freezing compartment 11 are provided.

그리고 본체(10)의 후벽에는 냉기를 생성하는 증발기(16)가 설치되고, 증발기(16)의 상측에는 냉기를 냉동실(11)과 냉장실(12)로 강제 토출하는 냉각팬(17)이 설치된다. 그리고 이 냉각팬(17)에 의하여 강제 송풍되는 냉기를 냉동실(11)과 냉장실(12)로 안내하는 냉기덕트(19)(20)가 설치된다.The rear wall of the main body 10 is provided with an evaporator 16 for generating cold air, and a cooling fan 17 for forcibly discharging the cold air into the freezing chamber 11 and the refrigerating chamber 12 is provided above the evaporator 16. . The cold air ducts 19 and 20 for guiding the cold air forcedly blown by the cooling fan 17 to the freezing chamber 11 and the refrigerating chamber 12 are provided.

이 냉기덕트(19)(20)는 냉동실측 덕트(19)와 냉장실측 덕트(20)로 구분되어 마련된다.The cold air ducts 19 and 20 are divided into a freezer compartment side duct 19 and a refrigerator compartment side duct 20.

한편, 냉장고는 냄새가 강한 음식물의 냄새가 타 음식물에 배거나 냉장고 도어의 개방시 냉장고 내부의 냄새가 실내로 유출되는 것을 방지하기 위해 냉장고 내부에서 냄새를 발생시키는 악취물질을 분해 제거하는 냉장고 탈취장치를 통상적으로 구비하고 있다.Meanwhile, the refrigerator is a refrigerator deodorizer for decomposing and removing odorous substances that cause odors in the refrigerator in order to prevent the smell of strong odors from being eaten by other foods or when the door of the refrigerator is opened. It is usually equipped with.

특히 우리나라의 식생활은 김치, 장류 등 발효식품이 발달하였는데 이러한 발효식품들은 심한 냄새를 발하게 되므로 국내에서 사용되는 냉장고의 탈취장치는 탈취성능이 더욱 우수하도록 제작될 필요가 있다 할 것이다.In particular, Korea's diet has been developed fermented foods such as kimchi, jangjang, etc. These fermented foods will give a bad smell, so the deodorizer of the refrigerator used in Korea will need to be made to be more deodorant performance.

종래에도 냉장고의 탈취를 위해 활성탄을 내부에 장착하는 기술이 개발되어 있으나, 시간이 경과됨에 따라 성능이 반감되어나 전체적으로 수명이 짧고 성능이 우수하지 못한 단점이 있었다.Conventionally, a technology for mounting activated carbon therein for deodorization of a refrigerator has been developed, but the performance is halved as time passes, but the overall life is short and the performance is not excellent.

또한 종래에 오존을 이용한 탈취장치는 오존(O3)의 영향으로 재질이 변성(노화, 변색 등)되며, 가격이 비싸다는 문제점이 있었다.In addition, in the conventional deodorization device using ozone, the material is denatured (aging, discoloration, etc.) under the influence of ozone (O 3 ), there was a problem that the price is expensive.

본 발명은 상술한 바와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 냉장고의 냉기덕트를 항균 기능을 갖는 나노실버가 함유된 수지재로 대체하여 냉기덕트에서 균류가 서식하는 것을 방지할 수 있으며, 악취 발생을 억제할 수 있는 항균/탈취 기능을 갖는 냉장고의 냉기덕트를 제공하는 것이다.The present invention is to solve the problems as described above, an object of the present invention is to replace the cold air duct of the refrigerator with a resin material containing nano-silver having an antibacterial function to prevent the infestation of fungi in the cold air duct To provide a cold air duct of the refrigerator having an antibacterial / deodorizing function that can suppress the generation of odor.

이와 같은 목적을 실현하기 위한 본 발명은 냉기덕트를 구비한 냉장고에 있어서, 상기 냉기덕트를 형성하는 수지재에 항균 기능을 갖는 나노실버가 함유되는 것을 특징으로 한다.The present invention for achieving the above object is characterized in that in the refrigerator provided with a cold air duct, a nano silver having an antibacterial function is contained in a resin material forming the cold air duct.

도 1은 종래의 냉장고의 측단면도.1 is a side cross-sectional view of a conventional refrigerator.

이하, 본 발명의 가장 바람직한 실시예를 첨부한 도면을 참조하여 본 발명의 기술분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있도록 더욱 상세히 설명하기로 한다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

은(Ag)은 범용적인 항균제로서 잘 알려진 물질로서 콜로이드 형태의 은은 세균을 비롯한 균류 및 바이러스 등에도 탁월한 효과가 있으면서도 부작용은 없는 것으로 알려져 있다. 특히 은이 미세 입자(1-100 nm)로 분산되어진 나노 실버 용액의 경우에는 쉽게 세포 속으로 침투하여 바이러스, 박테리아, 곰팡이 균류 등이 호흡할 때 필요한 효소의 기능을 정지시켜 질식시킴으로서 이들을 죽게 한다. 이는 병균의 신진대사를 막아 살균하는 것과 더불어 금속의 은이 방출하는 은의 전기적 부하가 병균의 생식 기능을 억제하기 때문이다.Silver (Ag) is a material that is well known as a general-purpose antimicrobial agent. Colloidal silver is known to have excellent effects on bacteria, fungi and viruses, but also has no side effects. Especially in the case of nano silver solution in which silver is dispersed into fine particles (1-100 nm), it easily penetrates into cells and kills them by suffocating by stopping the function of enzymes necessary for breathing by viruses, bacteria, and fungi. This is because the germ's metabolism is prevented and sterilized, and the silver's electrical load from the silver inhibits germ's reproductive function.

미세 입자의 은은 전기분해법, 액상환원법, 그라인딩(grinding) 등의 물리적 방법으로 제조되어질 수 있다. 고순도의 안정한 나노 실버를 얻기 위해서는 주로 전기분해법이 사용되었다. 전기분해법은 증류수에 순수한 은(99.99%)을 넣고 저온에서 저전류를 발생시켜 방전되어 나온 극소 미립자 형태의 은이 용액에 용해되어 포함되게 함으로서 얻을 수 있다.Silver of the fine particles may be prepared by physical methods such as electrolysis, liquid phase reduction, grinding (grinding). Electrolysis was mainly used to obtain stable nano silver with high purity. Electrolysis can be obtained by putting pure silver (99.99%) in distilled water and generating a low current at low temperature to dissolve and contain the silver in the form of microparticles discharged.

본 발명에 따른 항균/탈취 기능을 갖는 냉장고의 냉기덕트를 형성하는 수지재는 범용 수지에 항균/탈취 기능을 갖는 나노실버가 혼합된 복합수지로 제조되는 것을 특징으로 한다.The resin material forming the cold air duct of the refrigerator having an antibacterial / deodorizing function according to the present invention is characterized in that it is made of a composite resin in which nanosilver having an antibacterial / deodorizing function is mixed with a general-purpose resin.

이와 같이 제조된 항균/탈취 기능을 갖는 냉기덕트는 냉기가 냉동실 및 냉장실에 강제 송풍되면서 냉기덕트의 표면에 달라붙는 박테리아, 곰팡이 균류 등이 호흡할 때 필요한 효소의 기능을 정지시켜 제거시킬 수 있으며, 악취 발생을 억제할 수 있다.The cold air duct having the antibacterial / deodorizing function manufactured as described above can be removed by stopping the function of enzymes required when breathing bacteria, fungi and fungi that adhere to the surface of the cold air duct while the cold air is forcedly blown into the freezer compartment and the refrigerating compartment. Odor can be suppressed.

이상에서 설명한 것은 본 발명에 따른 항균/탈취 기능을 갖는 냉장고의 냉기덕트의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와 같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described above is only an embodiment of the cold air duct of the refrigerator having an antibacterial / deodorizing function according to the present invention, the present invention is not limited to the above embodiment, as claimed in the following claims of the present invention Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.

상술한 바와 같이, 냉장고의 냉기덕트를 항균 기능을 갖는 나노실버가 함유된 수지재로 대체하여 냉기덕트에서 균류가 서식하는 것을 방지할 수 있으며, 악취 발생을 억제할 수 있다.As described above, by replacing the cold air duct of the refrigerator with a resin material containing nano-silver having an antibacterial function, it is possible to prevent the infestation of fungi in the cold air duct, and to suppress the occurrence of odor.
