Description

냉기순환구조를 구비한 냉장고{REFRIGERATOR HAVING STRUCTURE FOR CIRCULATION OF COOLING AIR}REFRIGERATOR HAVING STRUCTURE FOR CIRCULATION OF COOLING AIR}

본 발명은 냉장고의 냉기순환구조에 관한 것으로서, 상세하게는, 냉장실의 도어 바스켓 부위 및 선반의 수납물을 보다 단시간 내에 냉각할 수 있는 냉기순환구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold air circulation structure of a refrigerator, and more particularly, to a cold air circulation structure capable of cooling a door basket portion of a refrigerating compartment and a storage of a shelf in a shorter time.

일반적으로, 냉장고는 제빙용기 및 냉동식품을 설정된 온도하에서 보관하기 위한 냉동실과 냉장대상물이 수납되는 냉장실로 구획되며, 냉동실 및 냉장실 고내에는 냉동사이클로 순환하는 냉매에 의해서 변환된 차가운 공기가 제공되어 식품을 장시간 보관하게 한다.In general, a refrigerator is divided into a freezer compartment for storing an ice making container and a frozen food at a set temperature, and a refrigerating compartment in which a refrigeration object is stored. In the freezer compartment and the refrigerating compartment, cold air converted by a refrigerant circulating in a freezing cycle is provided. Keep it for a long time.

도 1 내지 도 3은 종래의 냉장고의 냉기공급구조를 도시한 것으로서, 도 1은 종단면도, 도 2는 도 1의 A-A 단면도, 도 3은 도 1의 B-B 단면도이다.1 to 3 show a cold air supply structure of a conventional refrigerator, FIG. 1 is a longitudinal sectional view, FIG. 2 is a sectional view taken along line A-A of FIG. 1, and FIG. 3 is a sectional view taken along line B-B of FIG.

도시된 바와 같이, 종래의 냉장고는 단열재가 충진된 베리어(5)에 의하여 냉동실(2)과 냉장실(4)로 구획되고, 냉동실(2)의 후측에는 냉각기실(1)이 형성되며, 냉동실(2)과 냉장실(4)의 전면에는 개폐가능하도록 도어(20,40)가 설치되어 있다.As shown, the conventional refrigerator is partitioned into a freezer compartment 2 and a refrigerating compartment 4 by a barrier 5 filled with heat insulating material, and a cooler chamber 1 is formed at a rear side of the freezer compartment 2, and a freezer compartment ( 2) and the front of the refrigerating chamber (4) is provided with doors 20 and 40 to be opened and closed.

저온저압의 냉매가 통과하는 증발기(6)에서 열교환이 이루어지며, 냉기의 일부는 축류팬(8)에 의해 쉬라우드(12)를 거쳐 냉동실(2)로 공급되고, 나머지 일부는 상기 쉬라우드(12)를 거쳐 자유낙하하여 냉장실(2)로 공급된다.Heat exchange takes place in the evaporator 6 through which the low-temperature low-pressure refrigerant passes, and part of the cold air is supplied to the freezing chamber 2 through the shroud 12 by the axial fan 8, and the other part of the shroud ( Free fall through 12) is supplied to the refrigerating chamber (2).

냉각기실(1)로부터 냉장실(4)로 공급되는 냉기는, 쉬라우드(12)의 하면 일측에 형성된 흡입구로 흡입되어, 그 흡입구의 하방으로 형성된 냉기공급유로(31)를통과하여, 베리어(5)의 내부에 형성된 2개의 분기유로(32,33)로 나누어진다.The cold air supplied from the cooler chamber 1 to the refrigerating chamber 4 is sucked into the suction port formed on one side of the lower surface of the shroud 12, and passes through the cold air supply passage 31 formed below the suction port, so that the barrier 5 It is divided into two branching flow paths 32 and 33 formed inside the.

좌측 분기유로(32) 측으로 분기된 냉기의 일부는 냉장실의 배면에 길이방향으로 설치되는 배면 분기유로(30)를 통과하여 복수개의 배면 토출구(30a)를 통해 토출되고, 일부는 그대로 진행하여 냉장실(4)의 좌측면에 형성된 좌측 토출구(32a)를 통해 토출된다.A part of the cold air branched toward the left branch passage 32 passes through the rear branch passage 30 installed in the longitudinal direction on the rear surface of the refrigerating chamber, and is discharged through the plurality of rear discharge ports 30a, and part of the cold air flows as it is. It discharges through the left discharge port 32a formed in the left side of 4).

우측 분기유로(33) 측으로 분기된 냉기는 그 전부가 냉장실(4)의 우측면에 형성된 우측 토출구(33a)를 통해 토출된다.The cold air branched toward the right branch passage 33 is discharged through the right discharge port 33a formed in the right side of the refrigerating chamber 4 in its entirety.

이와 같이, 냉장실(4)의 배면 뿐만 아니라, 양측면에도 냉기의 토출구(32a, 33a)를 형성한 것은 냉장실내의 고른 온도분포를 꾀하기 위함이다.In this way, the discharge ports 32a and 33a for cold air are formed not only on the rear surface of the refrigerating chamber 4 but also on both sides thereof to achieve an even temperature distribution in the refrigerating chamber.

상기와 같은 과정을 통하여 냉동실(2) 및 냉장실(4)로 공급된 냉기는 내부에 보관중인 식품과의 열교환을 거쳐 상대적으로 고온으로 되고, 고온이 된 공기는 베리어(5)의 내부에 형성된 냉동실 흡입유로(2a) 및 냉장실 흡입유로(4a)를 거쳐 다시 증발기(6) 부근으로 이동하게 된다.The cold air supplied to the freezer compartment 2 and the refrigerating compartment 4 through the above process becomes relatively high temperature through heat exchange with the food stored therein, and the air at high temperature is formed in the freezer compartment 5 of the barrier 5. The suction passage 2a and the refrigerating chamber suction passage 4a move to the vicinity of the evaporator 6 again.

그런데, 실제에 있어서 냉장고의 사용시 가장 문제가 되는 것은 도어의 개폐에 따른 냉기손실임에도 불구하고, 종래의 냉장고의 냉기공급구조에 있어서는 도어의 개폐 구조를 고려하지 않고 있다는 것이 문제점으로 지적되어 왔다.By the way, despite the cold air loss caused by the opening and closing of the door in the actual use of the refrigerator, it has been pointed out as a problem that the opening and closing structure of the door is not considered in the conventional cold air supply structure.

즉, 냉장고의 사용상 가장 출입이 빈번한 부위는 냉장실의 도어부위이며, 그 중에서도 가장 빈번한 곳은 도어의 바스켓 부위이므로, 냉장실 내부의 고른 냉각이라는 근원적인 목적을 달성하기 위해서는, 상기 도어의 바스켓 부위와 같이 가장 수납물의 출입이 빈번한 곳에 대한 집중냉각구조가 요청되는 것이다.That is, the most frequently used part of the refrigerator is the door part of the refrigerating compartment, and the most frequent part is the basket part of the door. Thus, in order to achieve the basic purpose of even cooling of the inside of the refrigerating compartment, as in the basket part of the door, The centralized cooling structure for the most frequent entry of the objects is required.

본 발명은 상기와 같은 문제점을 해결하여, 냉장실 내부의 고른 온도분포를 단시간 내에 달성할 수 있는 냉기순환구조를 구비한 냉장고를 제공하는 것을 그 목적으로 한다.SUMMARY OF THE INVENTION An object of the present invention is to provide a refrigerator having a cold air circulation structure capable of solving the above problems and achieving even temperature distribution in a refrigerating compartment within a short time.

냉장실 도어(40)가 개방되어 있는 경우, 상기 베리어 토출구(102)와 냉장실 도어 흡입구(103)의 접촉이 해제되므로, 상기 냉장실(4)로 공급되는 나머지 일부의 냉기는 베리어(5)의 내부에 형성된 베리어 공급유로(101), 베리어 토출구(102)를 통과하여 냉장실(4)의 하방을 향하여 토출되어 이른바 에어커튼을 형성한다.When the refrigerating compartment door 40 is opened, the contact between the barrier discharge port 102 and the refrigerating compartment door inlet 103 is released, and thus, the remaining part of the cold air supplied to the refrigerating compartment 4 is stored inside the barrier 5. Passed through the formed barrier supply passage 101 and the barrier discharge port 102 is discharged toward the lower side of the refrigerating chamber 4 to form a so-called air curtain.

이때, 냉장실 송풍팬(105)은 상기 송풍팬 스위치의 자동적 해제에 의해 회전구동을 중단한다.At this time, the refrigerating chamber blowing fan 105 stops the rotation drive by the automatic release of the blowing fan switch.

상기와 같은 과정을 통하여 냉동실(2) 및 냉장실(4)로 공급된 냉기는 내부에 보관중인 식품과의 열교환을 거쳐 상대적으로 고온으로 되고, 고온이 된 공기는 냉장실(4)의 상면에 형성된 냉기 흡입구(2a)를 통해 흡입되어, 다시 냉각기실(1) 내부에 장착된 증발기(6) 부근으로 이동하게 된다.The cold air supplied to the freezer compartment 2 and the refrigerating compartment 4 through the above process becomes relatively high temperature through heat exchange with the food stored therein, and the air having a high temperature is cold air formed on the upper surface of the refrigerating compartment 4. It is sucked through the suction port 2a, and moves to the vicinity of the evaporator 6 mounted in the cooler chamber 1 again.

본 발명은 냉장실 내부의 고른 온도분포를 단시간 내에 달성할 수 있는 냉기순환구조를 구비한 냉장고를 제공한다.The present invention provides a refrigerator having a cold air circulation structure that can achieve an even temperature distribution in the refrigerating compartment within a short time.
