Abstract

The present invention relates to a triple door type refrigerator comprising a refrigerator body having a storage chamber partitioned into three separate storage parts; a refrigerator door for opening or closing each storage part; a cold air duct on the rear wall of the refrigerator body to supply cold air; and a temperature change room to be installed on one of the storage parts. The storage parts comprise a first storage chamber for partitioning off a freezer; and second and third storage chambers for vertically partitioning off a fridge. The second and third storage chambers are connected to each other through a connection hole. The third storage chamber includes a direction change guide member for guiding cold air which has cooled the second storage chamber to flow to the refrigerator door pocket of the third storage chamber through the connection hole; and a blower fan joined to one end of the direction change guide member at the bottom of the connection hole to forcibly blow cold air. Therefore, the inside of the third storage chamber is uniformly cooled without a temperature departure as the cold air is prevented from escaping through a return hole.

Description

3도어 타입 냉장고{3 DOOR TYPE REFRIGERATOR}3 door type refrigerator {3 DOOR TYPE REFRIGERATOR}

본 발명은 3도어 타입 냉장고에 관한 것으로, 보다 상세하게는 상부 냉장실로부터 하부 냉장실로 유동하는 냉기가 냉장고 도어의 포켓 쪽으로 원활하게 공급되는 3도어 타입 냉장고에 관한 것이다.
The present invention relates to a three door type refrigerator, and more particularly, to a three door type refrigerator in which cold air flowing from an upper refrigerator compartment to a lower refrigerator compartment is smoothly supplied toward a pocket of a refrigerator door.

일반적으로, 냉장고는 냉매가 압축 - 응축 - 팽창 - 증발하는 냉동사이클을 반복함에 따라 냉장실과 냉동실 내부를 저온화시켜 음식물을 일정기간 동안 신선하게 유지시켜 주는 장치이다.Generally, a refrigerator is a device that keeps the food in a fresh state for a predetermined period by reducing the temperature of the refrigerating chamber and the freezing chamber as the refrigerant repeats a refrigerating cycle in which the refrigerant compresses - condenses - expands - evaporates.

이를 위해, 냉장고에는 냉매를 압축시키는 압축기와, 상기 압축기로부터 유입된 냉매를 외기에 의해 응축시키는 응축기와, 상기 응축기로부터 유입된 냉매를 감압시키는 팽창밸브와, 상기 팽창밸브를 통과한 냉매가 저압상태에서 증발됨에 따라 고내의 열을 흡수하는 증발기를 포함하여 구성된다.To this end, the refrigerator is provided with a compressor for compressing refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, an expansion valve for reducing the refrigerant introduced from the condenser, And an evaporator that absorbs heat in the furnace as it evaporates in the furnace.

한편, 냉장고는 냉동실과 냉장실이 상/하로 구획된 탑마운트 프리저(Top Mount Freezer)와, 냉장실과 냉동실이 상/하로 구획된 바텀 마운트 프리저(Bottom Mount Freezer), 및 냉동실과 냉장실이 좌/우측으로 구획된 사이드 바이 사이드(Side By Side)로 구분된다.Meanwhile, the refrigerator includes a top mount freezer in which the freezer and the refrigerating compartment are divided up and down, a bottom mount freezer in which the refrigerating compartment and the freezer are divided up and down, and the freezer and the refrigerating compartment in the left and right sides. It is divided into side by side partitioned.

최근에는 상기 사이드 바이 사이드 타입의 냉장고 구성을 개선한 구조로서, 일측에는 냉동실을 형성하고 타측에는 냉장실을 상하방향 2개의 공간으로 구획한 3도어 타입의 냉장고가 개발되고 있다.Recently, as a structure of the side-by-side type refrigerator is improved, a three-door type refrigerator having a freezer compartment on one side and a refrigerator compartment divided into two spaces in the up and down directions on the other side has been developed.

이하, 도 1과 도 2를 참조하여 종래기술에 따른 3도 타입의 냉장고에 대하여 설명한다.Hereinafter, a refrigerator of a 3 degree type according to the prior art will be described with reference to FIGS. 1 and 2.

도시한 바와 같이, 종래기술에 따른 3도 타입의 냉장고는 저장실을 각각 3개의 독립 저장부로 구획 형성한 냉장고 본체(10)와, 상기 독립 저장부(11,12,13)를 개폐하는 냉장고 도어(20)와, 상기 냉장고 본체(10) 후벽에 설치되어 냉기를 생성하는 증발기(30)와, 상기 증발기(30)로부터 생성된 냉기를 독립 저장부(12)로 안내하는 냉기덕트(40)를 포함하여 구성된다.As shown in the drawing, a refrigerator having a three degree type according to the related art includes a refrigerator main body 10 in which a storage compartment is divided into three independent storage units, and a refrigerator door for opening and closing the independent storage units 11, 12, and 13. 20), an evaporator 30 installed at the rear wall of the refrigerator main body 10 to generate cold air, and a cold air duct 40 for guiding the cold air generated from the evaporator 30 to the independent storage unit 12. It is configured by.

그리고, 상기 독립 저장부(13)에는 특정 저장물품의 온도특성에 맞추어 내부 온도를 가변시킬 수 있는 온도전환룸(50)이 설치된다.In addition, the independent storage unit 13 is provided with a temperature conversion room 50 that can vary the internal temperature in accordance with the temperature characteristics of the particular storage article.

상기 증발기(30)로부터 생성된 냉기는 상기 냉기덕트(40)를 따라 유동하여 상부 독립 저장부(12)로부터 하부 독립 저장부를 통해 다시 리턴홀(42)로 유입되는 냉기순환 과정을 반복한다.The cold air generated from the evaporator 30 repeats the cold air circulation process flowing along the cold air duct 40 and flowing back from the upper independent storage 12 to the return hole 42 through the lower independent storage.

그런데, 종래기술에 따른 3도 타입의 냉장고 경우, 냉기덕트(40)로부터 토출된 냉기가 상부 독립 저장부(12)를 냉각시킨 후 하부 독립 저장부(13)로 이동 중 많은 양의 냉기가 리턴홀(42)로 빠져나가는 구조적인 문제점으로 인하여 하부 독립 저장부(13)는 전체적으로 균일한 냉장효과를 기대할 수 없는 문제점이 있었다.
However, in the case of the refrigerator having a 3 degree type according to the related art, a large amount of cold air is returned while the cold air discharged from the cold air duct 40 cools the upper independent storage unit 12 and moves to the lower independent storage unit 13. Due to a structural problem exiting the hole 42, the lower independent storage unit 13 has a problem that the overall refrigeration effect can not be expected.
