Description
본 발명은 냉장고에 관한 것으로서, 보다 상세하게는 본체의 저장실 내부로 냉기를 연속적으로 공급·순환시킴으로써 저장실 내부의 온도분포를 항상 일정하게 유지시킬 수 있도록 한 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator in which a temperature distribution in a storage compartment can be constantly maintained by continuously supplying and circulating cold air into a storage compartment of a main body.
일반적으로, 냉장고는 식품의 저온저장을 목적으로 하는 장치로서, 냉동사이클의 증발기로부터 열 교환된 냉기를 이용하여 각종 식품을 장기간 신선하게 유지할 수 있도록 한 것이다.In general, a refrigerator is a device for low temperature storage of food, and is intended to keep various foods fresh for a long time by using cold air heat exchanged from an evaporator of a refrigeration cycle.
이러한 냉장고는 저장실 내부로 냉기를 연속적으로 공급·순환시킬 수 있도록 하기 위해 저장실과 연통되는 냉기유입구 및 냉기토출구가 형성되어 있는 냉기덕트가 설치된다.The refrigerator is provided with a cold air duct in which a cold air inlet and a cold air outlet are formed to communicate with the storage compartment so as to continuously supply and circulate the cold air into the storage compartment.

Communicating cold air chambers 70 are provided respectively.
제2냉기덕트(50)는 램프케이스(44)의 상부에 일체로 형성되거나 또는 램프케이스(44)의 상부에 착탈 가능하도록 형성되는 것이 바람직하며, 그 결합방법은 다양하게 변경 가능하다. The second cold air duct 50 may be integrally formed on the upper portion of the lamp case 44 or may be formed to be detachable from the upper portion of the lamp case 44. The coupling method may be variously changed.

The second cold air duct 50 includes a lower case 52 connected to the lamp case 44 and an upper case 54 coupled to an upper side of the lower case 52, and an indoor lamp 42 therein. It is preferable to install the heat insulating member 60 so as to prevent the dew is generated on the outside of the lamp case 44 by heat exchange with). The heat insulating member 60 has a shape capable of covering the lower case 54 of the second cold air duct 50. In addition, the lower case 54 itself may be formed of a heat insulating material without using a separate heat insulating member 60, and thus a problem in which dew occurs in the lamp case 44 by heat exchange with the indoor lamp 42 may be solved.
또한, 필요에 따라 제2냉기덕트(50)는 일체로 구성할 수 있으며, 이 때의 단열부재(60) 설치는 상기에서 설명한 것과 동일하다.In addition, if necessary, the second cold air duct 50 may be integrally configured, and the heat insulation member 60 may be installed at the same time as described above.

It serves to discharge forward. On the cold air discharge port of the cold air chamber 70, it is preferable to provide a cold air dispersion member 80 so as to evenly distribute the cold air discharged to the storage chamber 22 in front of the main body 20.
냉기분산부재(80)는 냉기를 본체(20)의 저장실(22) 내부로 분산시킬 수 있는 범위 내에서 에어샤워형 플레이트 등과 같이 공지된 다양한 형태의 것을 선택적으로 적용 가능하다.The cold air dispersing member 80 may be selectively applied to various types of known forms such as an air shower plate within a range capable of dispersing cold air into the storage compartment 22 of the main body 20.
한편, 미설명 참조부호 46은 램프케이스(44)에 결합되는 램프커버, 53은 제1냉기덕트(30)와 연통되는 냉기유입홀을 도시한 것이다.On the other hand, reference numeral 46 is a lamp cover coupled to the lamp case 44, 53 shows a cold air inlet hole in communication with the first cold air duct (30).
상기에서 설명한 냉장고의 냉기덕트에 의한 냉기흐름을 간단하게 설명하면 하기와 같다.The cold air flow due to the cold air duct of the refrigerator described above is briefly described as follows.
증발기(미도시)로부터 열 교환된 냉기는 본체(20)의 후방에 설치되어 있는 제1냉기덕트(30)를 통해 상부로 이동되고, 이 냉기는 다시 제1냉기덕트(30)와 연통 설치되어 램프유니트(40)의 램프케이스(44)상에 위치하고 있는 제2냉기덕트(50)를 통과한다.The cold air heat exchanged from the evaporator (not shown) is moved upward through the first cold air duct 30 installed at the rear of the main body 20, and the cold air is again communicated with the first cold air duct 30. Passes through the second cold air duct 50 located on the lamp case 44 of the lamp unit 40.
제2냉기덕트를 통과한 냉기는 냉기챔버(70) 및 냉기분산부재(80)를 거쳐 본체(20)의 저장실(22) 전방으로 토출된다.The cold air passing through the second cold air duct is discharged to the front of the storage chamber 22 of the main body 20 through the cold air chamber 70 and the cold air dispersing member 80.
이상에서 설명한 바와 같이 본 발명에 따르면, 상대적으로 온도의 변화가 많은 본체의 저장실 전방으로 냉기를 토출시킴으로써 저장실 내부의 온도분포를 신속하게 균일화할 수 있으며, 그에 따라 냉장고의 냉각효율을 향상시킬 수 있다는 장점이 있다.As described above, according to the present invention, by discharging cold air to the front of the storage compartment of the main body having a relatively large temperature change, it is possible to quickly uniformize the temperature distribution inside the storage compartment, thereby improving the cooling efficiency of the refrigerator. There is an advantage.
또한, 제2냉기덕트를 램프유니트상에 일체로 형성하여 상대적으로 공간활용의 효율성을 높일 수 있다. In addition, by forming the second cold air duct integrally on the lamp unit, it is possible to relatively increase the efficiency of space utilization.
