Description

냉장고의 냉기순환구조{STRUCTURE FOR CIRCULATION OF COOLING AIR IN REFRIGERATOR}Cold air circulation structure of the refrigerator {STRUCTURE FOR CIRCULATION OF COOLING AIR IN REFRIGERATOR}

본 발명은 냉장고의 냉기순환구조에 관한 것으로서, 상세하게는, 냉장실의 배면 및 좌우측면에 형성된 냉기 토출구를 통해 토출되는 냉기의 양을 균형있게 조절하기 위한 냉기의 유로구성에 관한 것이다.The present invention relates to a cold air circulation structure of a refrigerator, and more particularly, to a constitution of a flow path of cold air for balancing the amount of cold air discharged through cold air discharge ports formed on the rear and left and right sides of the refrigerator compartment.

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 4는 종래의 냉장고의 냉기공급구조를 도시한 것으로서, 도 1은 정단면도, 도 2는 도 1의 A-A' 단면도, 도 3은 도 1의 A-A" 단면도, 도 4는 도 1의 B-B 단면도이다.1 to 4 illustrate a cold air supply structure of a conventional refrigerator, FIG. 1 is a sectional front view, FIG. 2 is a sectional view taken along line AA ′ of FIG. 1, FIG. 3 is a sectional view taken along line AA ′ of FIG. 1, and FIG. BB cross section.

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 형성된다.As shown, the conventional refrigerator is partitioned into a freezer compartment 2 and a refrigerating compartment 4 by a barrier 5 filled with heat insulators, and a cooler chamber 1 is formed at the rear side of the freezer compartment 2.

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, 이와 같은 종래의 냉장고의 냉기공급구조에 있어서는, 흡입구가 냉장실의 상측면에 형성되므로, 냉장실 저면의 말단까지 고른 냉각을 달성할 수 없다는 문제점이 있었고, 특히, 최하단에 위치하는 야채저장상자(15)에는 냉기가 제대로 전달되지 못한다는 문제점이 있었다.By the way, in the conventional cold air supply structure of the refrigerator, since the suction port is formed on the upper side of the refrigerating compartment, there is a problem that even cooling to the end of the bottom of the refrigerating compartment can not be achieved, and in particular, the vegetable storage box ( 15) there was a problem that the cold air is not properly delivered.

본 발명은 상기와 같은 문제점을 해결하여, 냉장실의 내부 저면까지 고른 냉각을 할 수 있고, 냉장실 내의 악취문제를 해소할 수 있는, 보다 진일보한 냉장고의 냉기순환구조를 제공하는 것을 그 목적으로 한다.An object of the present invention is to provide a cold air circulation structure of a refrigerator that can solve the above problems, even cooling to the inner bottom of the refrigerating compartment, and solve the odor problem in the refrigerating compartment.
