냉장고{Refrigerator}Refrigerator {Refrigerator}

본 고안의 목적은 커버부와 단열부로 이루어진 냉기 토출덕트에서 커버부와 단열부를 일체형 구조로 제작함으로써 성에 착상 및 조립 오차 문제를 해결하고, 커버부와 단열부를 접착시키는 별도의 조립 공정을 생략할 수 있는 냉장고를 제공하는 것이다.The object of the present invention is to solve the problem of frost formation and assembly error by manufacturing the cover and the heat insulating part in an integrated structure in the cold air discharge duct consisting of the cover and the heat insulating portion, it is possible to omit a separate assembly process for bonding the cover and the heat insulating portion. To provide a refrigerator.

일반적인 냉장고는 단열구조로 된 본체내의 상부 및 하부에 각각 냉동 및 냉장 식품 등을 보관하기 위한 냉동실 및 냉장실이 구획되도록 형성되고, 증발기로부터 생성된 냉기를 냉각팬의 작동에 의해 고내로 토출시키기 위한 냉기 토출덕트가 설치된다.The general refrigerator is formed so that the freezer compartment and the refrigerating compartment for storing frozen and refrigerated foods, respectively, are partitioned on the upper and lower portions of the main body having a heat insulating structure, and the cold air for discharging the cold air generated from the evaporator into the refrigerator by the operation of the cooling fan. The discharge duct is installed.

이러한 종래의 냉기 토출덕트는 복수개의 냉기 토출구가 형성된 커버부와 상기 냉기 토출구에 대응되는 냉기 토출구가 형성되어 상기 커버부의 후면에 조립되는 단열부로 구성되어 있다. 상기 커버부는 폴리프로필렌(PP)재질로 이루어지므로, 폴리스틸렌(PS)재질인 발포폴리스틸렌(EPS)로 이루어진 상기 단열부와는 인써트 사출성형으로 서로 접착이 되지 않는다.The conventional cold air discharge duct is composed of a cover portion formed with a plurality of cold air discharge ports and a heat insulation unit formed with a cold air discharge port corresponding to the cold air discharge port and assembled to the rear surface of the cover part. Since the cover part is made of polypropylene (PP) material, the heat insulating part made of expanded polystyrene (EPS), which is a polystyrene (PS) material, is not adhered to each other by insert injection molding.

따라서, 상기 커버부와 단열부는 각각 별도로 생산하여 접착제나 테이프 등 을 이용한 접착 방식을 이용하여 서로 조립할 수 밖에 없었다.Therefore, the cover part and the heat insulating part were produced separately, and were inevitably assembled together using an adhesive method using an adhesive or a tape.

이러한 종래의 냉장고에서 냉기 토출덕트는 조립시에 커버부와 단열부간에 조립 공차가 발생하여 커버부와 단열부 사이 틈새의 성에 착상 및 조립 단계에서 커버부와 단열부의 냉기 토출구의 위치가 서로 불일치되는 이유로 인해 원하는 냉각 성능을 얻을 수 없는 경우도 있다.The cold air discharge duct in the conventional refrigerator has an assembly tolerance between the cover part and the heat insulating part at the time of assembling, so that the positions of the cold air discharge ports of the cover part and the heat insulating part are inconsistent with each other during the conception of the gap between the cover part and the heat insulating part. For some reason, the desired cooling performance may not be achieved.

따라서, 종래의 냉장고에서 냉기 토출덕트는 앞서 언급한 성에 착상 및 냉기 토출구 간섭 등의 문제가 발생할 소지가 있는 상태로 제품에 적용되고 있기 때문에 확실한 품질을 기대하기 어렵고, 제품을 생산하는데 있어서 추가적인 부품과 공정이 발생하게 되는 문제점이 있다.Therefore, in the conventional refrigerator, since the cold air discharge duct is applied to the product in a state in which there is a possibility that the above-mentioned problems such as the conception of the castle and the cold air outlet interference occur, it is difficult to expect reliable quality, and additional components and There is a problem that the process occurs.
