본 발명은 질소주입형 김치냉장고에 관한 것이다.The present invention relates to a nitrogen injection kimchi refrigerator.

과일,채소류 등 음식물은 그 보관에 있어 신선도 유지가 중요하다. 그런데 공기는 질소가스와 산소가 대부분을 차지한다. 그 중에서도 질소가스는 과일이나 채소류등을 오래동안 보존할 때 신선도가 유지되도록 하는 효과가 있는 것으로 잘 알려져 있다. 질소가스는 주기율표상 원소기호 7번으로 무색,무미,무취의 기체이며, 액체나 고체로 상태가 변해도 색깔이 없다. 또한 질소가스는 비활성이어서 상온에서는 다른 원소와 거의 반응하지 않아 안정하다. 따라서 질소가스는 연소를 돕지 않고 호흡에 관여하지 않으며 질소 그 자체로는 유독하지 않아 인체에 무해하기 때문에 과일이나 채소류등 음식물 보관에 이용되고 있다.Food and other foods such as fruits and vegetables are important for keeping fresh. However, the air is made up of nitrogen gas and oxygen. Among them, nitrogen gas is known to have the effect of maintaining the freshness when preserving fruits and vegetables for a long time. Nitrogen gas is a colorless, tasteless, and odorless gas with element number 7 in the periodic table, and has no color even when its state changes to liquid or solid. In addition, nitrogen gas is inert and stable at room temperature because it hardly reacts with other elements. Therefore, nitrogen gas does not help combustion and does not participate in respiration. Nitrogen itself is not toxic and harmless to human body, so it is used for food and storage of fruits and vegetables.

그럼에도 불구하고 기존의 김치냉장고는 저장물의 신선도 유지를 온도에만 의존하여 왔다. 따라서 저장물의 신선도 유지에 한계가 존재하는 문제점이 있었다.

먼저 첨부한 도면을 근거로 산소발생기(200)를 상세히 설명한다.First, the oxygen generator 200 will be described in detail with reference to the accompanying drawings.

설명에 앞서 산소발생기(200)에 대하여 간략히 소개하면, 산소발생기(200)란 촉매나 분리막을 이용하여 공기 중의 질소가스와 산소를 분리하여 농축하는 장치로서, 촉매로는 주로 산소와 질소가스가 흡착되는 정도가 상이한 제올라이트(zeolite)가 이용된다.Before briefly introducing the oxygen generator 200, the oxygen generator 200 is a device for separating and concentrating nitrogen gas and oxygen in the air by using a catalyst or a separator, mainly oxygen and nitrogen gas is adsorbed as a catalyst Zeolites with different degrees of use are used.

산소발생기(200)의 작동 원리를 간략히 설명하면, 산소발생기(200)는 공기흡입구(250)로부터 산소와 질소가스 등이 섞여있는 공기를 흡입한다. 산소발생기(200)는 흡입된 공기를 압축하여 제올라이트(zeolite)에 불어넣는 과정을 반복함으로써 흡입된 공기가 산소로 농축된 부분과 질소가스로 농축된 부분으로 분리시킨다.Briefly describing the operating principle of the oxygen generator 200, the oxygen generator 200 sucks air mixed with oxygen and nitrogen gas from the air inlet 250. The oxygen generator 200 compresses the sucked air and blows it into the zeolite to separate the sucked air into a portion concentrated with oxygen and a portion concentrated with nitrogen gas.

산소발생기(200)에 의하여 분리농축된 질소가스는 산소발생기(200)의 후면에 마련된 질소가스배출구(250)를 통하여 저장실(140)로 주입된다.The nitrogen gas separated and concentrated by the oxygen generator 200 is injected into the storage chamber 140 through the nitrogen gas outlet 250 provided at the rear of the oxygen generator 200.

따라서 저장실(140) 내의 야채나 채소류 등은 질소가스에 의하여 보다 신선한 상태를 오래 유지할 수 있게 된다.Therefore, vegetables, vegetables, etc. in the storage chamber 140 can maintain a fresh state longer by nitrogen gas.

또한 산소발생기(200)에 의하여 분리농축된 산소는 산소발생기(200)에 마련된 산소배출구(230)를 통하여 본체(100)의 외부로 방출된다.In addition, the oxygen separated and concentrated by the oxygen generator 200 is discharged to the outside of the main body 100 through the oxygen outlet 230 provided in the oxygen generator 200.

따라서 질소가스주입 김치냉장고가 위치한 본체(100) 주위의 공기는 질소가스주입 김치냉장고를 가동하기 전보다 산소가 차지하는 비율이 높아지기 때문에 공기청정의 효과를 얻을 수 있다.Therefore, the air around the main body 100 where the nitrogen gas injection kimchi refrigerator is located has a higher oxygen occupancy ratio than before the nitrogen gas injection kimchi refrigerator is operated, thereby obtaining the effect of air cleaning.
