Description

리턴덕트에 항균덕트가 구비된 냉장고{REFRIGERATOR WITH THE ANTI-BIOTIC DUCT INSTALLED IN A RETURN DUCT}REFRIGERATOR WITH THE ANTI-BIOTIC DUCT INSTALLED IN A RETURN DUCT}

본 발명은 리턴덕트에 항균덕트가 구비된 냉장고에 관한 것으로서, 보다 상세하게는 냉동실 및 냉장실로 공급되어 순환을 위해 리턴덕트로 유입된 냉기에 포함된 바이러스, 박테리아, 곰팡이 등의 유해세균을 나노 실버에 의해 살균시키는 리턴덕트에 항균덕트가 구비된 냉장고에 관한 것이다.The present invention relates to a refrigerator equipped with an antimicrobial duct in the return duct, and more particularly, to nanoparticles of harmful bacteria such as viruses, bacteria, molds, and the like, which are supplied to the freezing compartment and the refrigerating compartment and introduced into the return duct for circulation. It relates to a refrigerator provided with an antibacterial duct in the return duct sterilized by.

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 food stored in the chamber is stored for a long time without deterioration. The refrigerator is a refrigerant compressed to high temperature and high pressure by the operation of a compressor. After refrigerant gas is liquefied in a condenser to change to a liquid state, it is decompressed through an expansion valve and evaporated in an evaporator to remove heat from outside air by the heat of evaporation of the refrigerant, thereby cooling. Device.

한편, 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. On the other hand, 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 no side effects.

특히, 은이 미세 입자(1-100nm)로 분산된 나노 실버 용액의 경우에는 쉽게 세포 속으로 침투하여 바이러스, 박테리아, 곰팡이 등이 호흡할 때 필요한 효소의 기능을 정지시켜 질식시킴으로써 이들을 죽게 한다. 즉, 이것은 미세 입자의 은이 바이러스 등의 신진대사를 정지시켜 살균시킴과 아울러 금속의 은으로부터 방출되는 은의 전기적 부하가 바이러스 등의 생식 기능을 억제하기 때문이다. In particular, nano silver solution in which silver is dispersed into fine particles (1-100 nm) easily penetrates into cells and kills them by suffocating by stopping the function of enzymes required when viruses, bacteria, and fungi breathe. In other words, this is because silver of fine particles stops and sterilizes metabolism of viruses and the like, and the electrical load of silver released from silver of metals suppresses the reproductive function of viruses and the like.

미세 입자의 은은 전기분해법, 액상환원법, 그라인딩(grinding) 등의 물리적 방법으로 제조될 수 있으며, 고순도의 안정된 나노 실버를 얻기 위해서는 지금까지 주로 전기분해법이 사용되고 있다.Silver of the fine particles may be prepared by physical methods such as electrolysis, liquid phase reduction, grinding, etc., and electrolysis is mainly used to obtain stable nano silver with high purity.

전기분해법은 증류수에 순수한 은(99.99%)을 넣고 저온에서 저전류를 발생시켜서 방전되어 나온 극소 미립자 형태의 은이 용액에 용해되어 포함되도록 하여 미세 입자의 은을 제조한다.In the electrolysis method, fine silver is prepared by adding pure silver (99.99%) to distilled water and generating a low current at low temperature so that the discharged silver particles are dissolved in the solution.

이와 같은 나노 실버의 실용화 기술을 냉장고의 항균 기능에 접목하고자 하는 연구 개발이 이루어지고 있다.Research and development is attempting to apply such a commercialization technology of nano silver to the antibacterial function of the refrigerator.

The antibacterial ducts 10 and 20 are provided for each partition 4c.

항균덕트(10,20)는 판상부재(11,21)의 일측면에 길이방향으로 나란하게 수직되도록 복수의 격판(12,22)이 일체로 형성되어 리턴덕트(4)의 격벽(4c)사이마다 각각 설치되어 리턴덕트(4)를 통과하는 냉기의 흐름을 가이드한다.The antimicrobial ducts 10 and 20 are integrally formed with a plurality of diaphragms 12 and 22 so as to be vertically parallel to one side of the plate members 11 and 21 in the longitudinal direction, so that the partition walls 4c of the return duct 4 are formed. Each of them is installed to guide the flow of cold air passing through the return duct (4).

항균덕트(10,20)는 도 3 및 도 4에 도시된 바와 같이, 냉동실(2)의 냉기흡입구(2c)를 통해 유입되는 냉기의 통로(4d)를 제공하는 격벽(4c)사이와 냉장실(3)의 냉기흡입구(3b)를 통해 유입되는 냉기의 통로(4e)를 제공하는 격벽(4c)사이에 각각 설치되도록 다양한 크기로 제작될 수 있다.3 and 4, the antibacterial ducts 10 and 20 are formed between the partition wall 4c and the refrigerating compartment (4c) which provide a passage 4d of the cold air introduced through the cold air inlet 2c of the freezer compartment 2.
