Description
본 발명은 냉장고의 냉기순환구조에 관한 것으로서, 상세하게는, 냉장실 내부에 식품 등이 가득 수납되어 냉기 토출구의 일부가 봉쇄되더라도, 냉장실 내부의 고른 냉각을 이룰 수 있는 냉기순환구조에 관한 것이다.The present invention relates to a cold air circulation structure of a refrigerator. Specifically, the present invention relates to a cold air circulation structure capable of achieving even cooling in a refrigerator compartment, even if food and the like are filled in the refrigerator compartment and a part of the cold air discharge port is blocked.
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, 상기와 같은 종래의 냉기순환구조에 있어서는 오직 하나의 냉기 공급유로를 통해 냉기가 공급될 뿐이므로, 냉장실 내부에 식품 등이 가득 수납되어 일부의 냉기 토출구를 봉쇄하게 될 경우, 토출의 불균형을 초래하게 되어 냉장실 내부의 효율적인 냉각을 이룰 수 없다는 점에서 문제점으로 지적되어 왔다.However, in the conventional cold air circulation structure as described above, since only cold air is supplied through only one cold air supply flow path, when the food and the like are filled in the refrigerating chamber to block some of the cold air discharge ports, an unbalanced discharge may be caused. It has been pointed out as a problem in that it can not achieve efficient cooling inside the refrigerator compartment.
본 발명은 상기와 같은 문제점을 해결하여, 냉장실 내부에 식품 등이 가득 수납되어 일부의 냉기 토출구를 봉쇄하더라도, 냉장실 내부의 고른 냉각을 이룰 수있는 냉기순환구조를 구비한 냉장고를 제공하는 것을 그 목적으로 한다.The present invention is to solve the above problems, even if the food is contained in the refrigerating chamber is filled with a portion of the cold air discharge port, to provide a refrigerator having a cold air circulation structure that can achieve an even cooling in the refrigerating compartment. It is done.

이하, 본 발명에 의한 냉기순환구조를 구비한 냉장고의 전체적 구조 및 작용에 관하여 설명하면 다음과 같다.Hereinafter, the overall structure and operation of the refrigerator having a cold air circulation structure according to the present invention will be described.
본 발명에 의한 냉장고는 단열재가 충진된 베리어(5)에 의하여 냉동실(2)과 냉장실(4)로 구획되고 냉동실(2)의 후측에는 냉각기실(1)이 형성된다.The refrigerator according to the present invention is partitioned into a freezer compartment 2 and a refrigerating compartment 4 by a barrier 5 filled with a heat insulating material, and a cooler chamber 1 is formed at the rear side of the freezer compartment 2.
도 4에 도시된 제1실시례의 경우, 저온저압의 냉매가 통과하는 증발기(6)에서 열교환이 이루어지며, 냉기의 일부는 제1송풍팬(103)의 압송에 의해 쉬라우드 (12)를 거쳐 냉동실(2)로 공급되고, 나머지 일부는 상기 쉬라우드(12)를 거쳐 자유낙하하여 제1냉기 공급유로(101)로 공급되며, 또 다른 일부는 증발기(6)의 후방에 형성된 제2송풍팬(104)의 압송에 의해 제2냉기 공급유로(102)로 공급된다.In the case of the first embodiment shown in Figure 4, the heat exchange is carried out in the evaporator 6 through which the low-temperature low-pressure refrigerant passes, a portion of the cold air to the shroud 12 by the pressure of the first blowing fan 103 Is supplied to the freezing chamber (2), the remaining part is free-falling through the shroud 12 and supplied to the first cold air supply passage 101, and another part is the second air blowing formed behind the evaporator (6) The fan 104 is supplied to the second cold air supply passage 102 by the pressure feeding of the fan 104.

한편, 도 5 및 도 6에 도시된 제2실시례의 경우, 저온저압의 냉매가 통과하는 증발기(6)에서 열교환이 이루어지며, 냉기의 일부는 제1송풍팬(103)의 압송에 의해 쉬라우드 (12)를 거쳐 냉동실(2)로 공급되고, 나머지 일부는 상기 쉬라우드 (12)를 거쳐 자유낙하하여 제1냉기 공급유로(101)로 공급되며, 또 다른 일부는 증발기(6)의 후방에 형성된 제2송풍팬(104)의 압송에 의해 제2냉기 공급유로(102)로 공급된다.Meanwhile, in the second embodiment illustrated in FIGS. 5 and 6, heat exchange is performed in the evaporator 6 through which the low temperature and low pressure refrigerant passes, and a part of the cold air is restrained by the pressure feeding of the first blowing fan 103. The wood 12 is supplied to the freezer compartment 2, and the remaining part is freely dropped through the shroud 12 and supplied to the first cold air supply passage 101, and the other part is rearward of the evaporator 6. The second cooling fan 104 is supplied to the second cold air supply passage 102 by the pressure feeding of the second blower fan 104 formed in the cooling fan 104.
제1냉기 공급유로(101) 및 제2냉기 공급유로(102)를 통해 공급된 냉기는 각각 냉장실(4) 내부의 배면에 형성된 제1냉기 토출구(110) 및 제2냉기 토출구(120)를 통해 토출되고, 내부에 보관중인 식품과의 열교환을 거쳐 상대적으로 고온으로 된 냉기는 베리어(5)의 내부에 형성된 냉장실 흡입유로(4a)를 거쳐 다시 냉각기실 (1)의 증발기(6) 부근으로 이동하게 된다.The cold air supplied through the first cold air supply passage 101 and the second cold air supply passage 102 may be formed through the first cold air outlet 110 and the second cold air outlet 120 formed on the rear surface of the refrigerating compartment 4, respectively. The cold air discharged and cooled to a relatively high temperature through heat exchange with the food stored therein is moved back to the evaporator 6 in the cooler chamber 1 through the refrigerating chamber suction channel 4a formed in the barrier 5. Done.
여기서, 제1냉기 토출구(110) 및 제2냉기 토출구(120)는 모두 냉장실(4) 내부의 동일한 면에 형성되어 있으나, 서로 그 공급유로의 구성을 달리 하고, 냉기 토출방향도 상방과 하방으로 서로 달리 하는 구성을 취하고 있으므로, 어느 한 편의 토출구가 냉장실(4) 내부에 수납된 식품 등에 의해 봉쇄되더라도 다른 토출구의 냉기토출이 가능하여, 냉장실(4) 내부의 고른 냉각을 달성할 수 있도록 한다.Here, although the first cold air outlet 110 and the second cold air outlet 120 are all formed on the same surface inside the refrigerating chamber 4, the configuration of the supply flow paths is different from each other, and the cold air discharge direction is also upward and downward. Since the configuration is different from each other, even if any one discharge port is sealed by food or the like stored in the refrigerating chamber 4, it is possible to discharge the cold air of the other discharge port, thereby achieving even cooling in the refrigerating chamber 4.
본 발명은 냉장실 내부에 식품 등이 가득 수납되어 일부의 냉기 토출구를 봉쇄하더라도, 냉장실 내부의 고른 냉각을 이룰 수 있는 냉기순환구조를 구비한 냉장고를 제공한다.The present invention provides a refrigerator having a cold air circulation structure capable of achieving even cooling in the refrigerating compartment, even if the food is filled in the refrigerating compartment to block some of the cold air discharge ports.
