한편, 상기 쉬라우드(4)의 전방에는 그릴팬(5)이 설치되는데, 상기 그릴팬(5)에는 냉동실(2)로 냉기를 분출할 수 있도록 복수개의 냉기토출공(5a)이 형성되어 있다. 그리고, 상기 쉬라우드(4)의 하부에서 베리어(1) 내를 통하여 냉장실(6)로 냉기를 안내하는 냉기유로(7)가 형성되어 있다. 또한 상기 쉬라우드(4) 상부에는 송풍팬(4a)이 설치되어 증발기(3)에서 발생한 냉기를 냉동실(2) 및 냉장실(6)로 불어내게 된다.Meanwhile, a grill pan 5 is installed in front of the shroud 4, and a plurality of cold air discharge holes 5a are formed in the grill pan 5 to eject cold air into the freezing chamber 2. . A cold air flow passage 7 is formed below the shroud 4 to guide cold air to the refrigerating chamber 6 through the barrier 1. In addition, a blower fan 4a is installed above the shroud 4 to blow out the cold air generated from the evaporator 3 to the freezing chamber 2 and the refrigerating chamber 6.

그리고 상기 베리어(1) 내부를 통하여 형성된 냉기유로(7)와 연통되어 냉장실(6) 후방을 통하여 냉장실덕트(8)가 형성되어 냉기유로(7)를 통한 냉기를 냉장실(6) 측으로 유입되고, 상기 냉장실덕트(8)에는 냉장실(6)의 내부로 냉기를 전달할 수 있도록 하는 냉기토출공(8a)이 높이차를 두고 차례로 형성되어 있다.In addition, the refrigerator 1 communicates with the cold air passage 7 formed through the inside of the barrier 1, and a refrigerating chamber duct 8 is formed through the rear side of the refrigerating chamber 6, thereby introducing cold air through the cold air passage 7 to the refrigerating chamber 6. In the refrigerating chamber duct (8), cold air discharge holes (8a) are formed in order with a difference in height so as to transfer cold air into the refrigerating chamber (6).

또한 베리어(1)의 상면과 저면을 통하여 각각 냉동실(2)과 냉장실(6)을 순환한 냉기가 귀환되는 입구(9a,9a')가 형성되며, 상기 입구(9a,9a')에서부터베리어(1) 내부를 통하여 냉동실(2)과 냉장실(6) 내부를 순환한 냉기를 증발기(3) 측으로 전달하기 위한 냉기귀환로(9)가 형성되는데, 상기 냉기귀환로(9)는 증발기(3) 하부측으로 연결되어 있다.In addition, inlets 9a and 9a 'are formed to return the cold air circulated through the freezer compartment 2 and the refrigerating compartment 6 through the top and bottom surfaces of the barrier 1, respectively. 1) A cold air return path 9 is formed for transferring cold air circulated inside the freezer compartment 2 and the refrigerating compartment 6 to the evaporator 3 side through the inside, and the cold air return path 9 is an evaporator 3. It is connected to the lower side.

이와 같은 구성의 종래의 냉장고에서, 냉기가 순환되는 과정을 설명한다. 증발기(3) 내부를 통과하는 저온의 냉매와 냉장고 내부를 순환하는 공기가 열교환하여 냉기가 형성된다. 상기 증발기(3)와 열교환되어 생성된 저온의 냉기는 송풍팬(4a)의 구동에 의해 쉬라우드(4)를 거쳐 일부는 그릴팬(5) 상에 형성된 냉기토출공(5a)을 통하여 냉동실(2)로 유입되고, 나머지의 냉기는 쉬라우드(4) 하부를 통해 베리어(1) 내부로 형성된 냉기유로(7)를 지나 냉장실덕트(8)로 유입되어 냉장실덕트(8)의 냉기토출공(8a)을 통하여 냉장실(6) 내부로 유입된다.In the conventional refrigerator having such a configuration, a process in which cold air is circulated will be described. The low temperature refrigerant passing through the evaporator 3 and the air circulating inside the refrigerator exchange heat to form cold air. The low temperature cold air generated by heat exchange with the evaporator 3 passes through the shroud 4 by the driving of the blower fan 4a and a part of the freezing chamber through the cold air discharge hole 5a formed on the grill fan 5. 2) and the remaining cold air flows into the refrigerating chamber duct (8) through the cold air passage (7) formed into the barrier (1) through the lower shroud (4) to the cold air discharge hole of the refrigerating chamber duct ( It flows into the refrigerating compartment 6 through 8a).

한편, 상기 냉동실(2) 내부로 유입된 냉기는 냉동실(2) 내부의 공기와 열교환되어 냉동실(2) 내부를 냉동시키고 냉동실(2) 하면(베리어상면)에 형성된 냉기귀환로 입구(9a)를 통해 냉기귀환로(9)를 거쳐 증발기(3)로 귀환된다. 그리고 냉장실(6) 내부로 유입된 냉기는 내부에서 냉각기능을 수행한 후 냉장실(6) 천정(베리어하면)에 형성된 냉기귀환로 입구(9a')를 통해 냉기귀환로(9)를 거쳐 귀환된다.On the other hand, the cold air introduced into the freezer compartment 2 is heat-exchanged with the air inside the freezer compartment 2 to freeze the inside of the freezer compartment 2, and the cold air return path inlet 9a formed on the lower surface of the freezer compartment 2 (upper barrier). Through the cold air return path (9) through the return to the evaporator (3). The cold air introduced into the refrigerating chamber 6 is returned through the cold air return passage 9 through the cold air return inlet 9a 'formed on the ceiling of the refrigerator compartment 6 after performing a cooling function therein. .

도면 중 미설명 부호 10,10'는 각각 냉장실 및 냉동실 도어이다.In the drawings, reference numerals 10 and 10 'denote refrigerator doors and freezer doors, respectively.

이와 같은 종래의 냉장고에서는 다음과 같은 문제점이 있다.Such a conventional refrigerator has the following problems.

즉, 상기 냉장실(6)은 상대적으로 그 체적이 크고, 상기 냉장실덕트(8)는 냉장실(6)의 후방 중앙을 따라 상하로 길게 설치되어 있어, 상기 냉장실덕트(8)를 통해 냉장실(6) 내부로 전달되는 냉기는 주로 냉장실의 중앙부분으로 전달되어, 도 2에 도시된 바와 같이, 냉장실(6)의 중앙영역은 과냉각영역(SA)을 형성하고, 주변부분과 도어(10) 근처는 약냉각영역(WA)을 형성하게 된다.That is, the refrigerating chamber 6 has a relatively large volume, and the refrigerating chamber duct 8 is installed up and down along the rear center of the refrigerating chamber 6, and the refrigerating chamber 6 is provided through the refrigerating chamber duct 8. The cold air delivered to the inside is mainly delivered to the center portion of the refrigerating compartment, and as shown in FIG. 2, the central region of the refrigerating compartment 6 forms the supercooling region SA, and the peripheral portion and the vicinity of the door 10 are approximately The cooling zone WA is formed.

따라서, 냉장실(6) 내부의 온도분포가 고르지 않게 된다. 특히 도 1에 도시된 바와 같이, 상기 냉장실(6)의 중앙에 큰 식품이 놓여 있을 경우 냉장실(6)의 중앙측으로 전달된 냉기가 제대로 순환되지 않고 정체되어 있게 되어 상기 약냉각영역(WA)의 온도는 더욱 올라가게 되어 냉장실(6) 내부의 온도불균일현상은 더욱 심해지게 된다.Therefore, the temperature distribution inside the refrigerating chamber 6 is uneven. In particular, as shown in Figure 1, when a large food is placed in the center of the refrigerating compartment 6, the cold air delivered to the central side of the refrigerating compartment 6 is not circulated properly, stagnated, so that the weak cooling area WA The temperature rises further and the temperature nonuniformity inside the refrigerating chamber 6 becomes more severe.

이와 같이 되면 보관되는 식품이 그 보관위치에 따라 과냉각되거나 냉각이 이루어지지 않게 되어 손상되는 문제점이 있다.In this case, there is a problem that the food is stored is not supercooled or cooled according to the storage position is damaged.

따라서, 본 발명의 목적은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로, 냉장실 내부로 전달되는 냉기를 냉장실 전체로 균일하게 공급되도록 하는 것이다.Therefore, an object of the present invention is to solve the conventional problems as described above, to uniformly supply the cold air delivered to the inside of the refrigerator compartment.

이하 상기한 바와 같은 본 발명에 의한 냉장고의 균일냉각장치의 바람직한 실시예를 첨부된 도면을 참고하여 상세하게 설명한다. 종래 기술의 것과 동일한 것은 동일 부호를 부여하여 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the uniform cooling apparatus of the refrigerator according to the present invention as described above will be described in detail. The same thing as the prior art will be described with the same reference numerals.

도 3에는 본 발명의 바람직한 실시예가 도시되어 있다. 이에 도시된 바에 따르면, 냉장고(20)의 내부에는 저장공간인 냉동실(30)과 냉장실(40)이 베리어(22)에 의해 구획되어 있고, 상기 냉동실(30)과 냉장실(40)로 냉기를 공급하는 증발기(25)가 상기 냉동실(30)의 후방에 구비된다. 그리고, 상기 증발기(25)의 전방에는 냉동실(30)과 냉장실(40)로 냉기를 분배하는 쉬라우드(28)가 설치되고, 상기 쉬라우드(28)의 전방에는 그릴팬(29)이 설치되어 상기 냉동실(30)과의 사이를 구획한다.3 shows a preferred embodiment of the present invention. As shown in the drawing, the freezer compartment 30 and the refrigerating compartment 40, which are storage spaces, are partitioned by the barrier 22 in the refrigerator 20, and supply cold air to the freezer compartment 30 and the refrigerating compartment 40. An evaporator 25 is provided at the rear of the freezer compartment 30. In addition, a shroud 28 for distributing cold air to the freezing chamber 30 and the refrigerating chamber 40 is installed at the front of the evaporator 25, and a grill pan 29 is installed at the front of the shroud 28. The space between the freezer compartment 30 is partitioned.

상기 냉동실(30)로는 상기 쉬라우드(28)와 그릴팬(29)을 거쳐 냉기가 공급되고, 상기 냉동실(30)의 바닥면을 형성하는 상기 베리어(22)의 내부에는 냉동실(30) 내부를 순환한 냉기를 증발기(25)로 귀환시키는 냉기귀환로(35)가 형성되어 있다.Cold air is supplied to the freezing chamber 30 through the shroud 28 and the grill pan 29, and an inside of the freezing chamber 30 is formed inside the barrier 22 forming the bottom surface of the freezing chamber 30. The cold air return path 35 which returns the circulated cold air to the evaporator 25 is formed.

그리고 상기 증발기(25)에서 생성된 냉기를 냉장실(40)로 공급하는 냉장실덕트(42)가 베리어(22)를 관통하여 상기 냉장실(40)의 후방에 설치된다. 상기 냉장실덕트(42)를 통해서는 상기 냉장실(40)의 내부의 높이차를 두고 냉기가 토출된다.In addition, a refrigerating chamber duct 42 for supplying the cold air generated in the evaporator 25 to the refrigerating chamber 40 passes through the barrier 22 and is installed at the rear of the refrigerating chamber 40. The cold air is discharged through the refrigerating chamber duct 42 with a height difference between the insides of the refrigerating chamber 40.

한편, 상기 냉장실(40)의 천정을 형성하는 베리어(22)의 하부에서 그 내부를 관통하여서는 냉장실 내부를 순환한 냉기는 상기 증발기(25)로 귀환시키는 냉기귀환로(45)가 형성되어 있다.On the other hand, the cold air circulating inside the refrigerating chamber through the lower portion of the barrier 22 forming the ceiling of the refrigerating chamber 40, the cold air return path 45 for returning to the evaporator 25 is formed.

그리고 상기 냉장실(40)의 천정에는 상기 냉장실(40) 내부의 냉기를 휘저어 냉기가 냉장실(40)에 정체되지 않게 하는 팬(50)이 설치된다. 이와 같은 팬(50)은 항상 회전하면서 냉장실(40) 내부로 토출된 냉기를 휘저어 줄 수도 있고, 예를 들면 상기 증발기(25)로부터 냉기가 공급될 때와 같이, 필요시에만 회전되면서 냉기가 냉장실(40)의 내부에 정체되지 않도록 할 수 있다.And the ceiling of the refrigerating chamber 40 is provided with a fan 50 to stir the cold air inside the refrigerating chamber 40 so that the cold air is not stagnant in the refrigerating chamber (40). The fan 50 may always stir the cold air discharged into the refrigerating chamber 40 while rotating, or, for example, when the cold air is supplied from the evaporator 25, the cold air rotates only when necessary, It is possible to prevent the congestion inside the 40.

이하 상기한 바와 같은 구성을 가지는 본 발명에 의한 냉장고의 균일냉각장치의 작용을 상세하게 설명한다.Hereinafter, the operation of the uniform cooling device of the refrigerator according to the present invention having the configuration as described above will be described in detail.

냉장고의 저장공간의 온도가 설정온도를 넘어서게 되면, 냉동사이클이 동작되어 상기 증발기(25)에서 냉매와 냉기사이의 열교환이 이루어지게 되고 냉기의 온도는 상대적으로 낮아지게 된다.When the temperature of the storage space of the refrigerator exceeds the set temperature, the refrigeration cycle is operated to exchange heat between the refrigerant and the cold air in the evaporator 25 and the temperature of the cold air is relatively low.

이와 같이 증발기(25)에서 형성된 냉기는 상기 쉬라우드(28)를 거쳐 냉동실(30)로 공급되어 그 내부를 순환한 후, 상기 냉기귀환로(35)를 통해 귀환되어 다시 증발기(25)로 전달된다.As described above, the cold air formed in the evaporator 25 is supplied to the freezing chamber 30 through the shroud 28, circulated therein, and then returned to the evaporator 25 through the cold air return path 35. do.

그리고, 상기 냉동실(30)로 전달되고 남은 나머지 냉기는 상기 냉장실덕트(42)로 전달되어 냉장실(40)로 전달된다. 이때 상기 냉장실덕트(42)에서는 냉장실(40)의 각각의 단으로 냉기를 토출한다.Then, the remaining cold air that is delivered to the freezing chamber 30 is transferred to the refrigerating chamber duct 42 and is delivered to the refrigerating chamber 40. At this time, the refrigerating chamber duct 42 discharges cold air to each stage of the refrigerating chamber 40.

한편, 상기 팬(50)은 회전하면서 상기 냉장실(40)으로 내부로 토출된 냉기가 정체되지 않고 도 4에 도시된 바와 같이 냉장실(40)의 상부에서 볼 때, 냉장실(40) 내부의 주변부를 따라 회전하면서 순환하게 한다.On the other hand, the cooling fan discharged into the refrigerating chamber 40 while the fan 50 is rotated, as seen from the top of the refrigerating chamber 40, as shown in Figure 4, as shown in Figure 4, the peripheral portion Rotate and circulate along.

상기와 같이 냉장실(4)의 내부를 순환하면서 저장물과 열교환된 냉기는 상대적으로 온도가 상승되면서 냉장실(40)의 상부로 상승되어 상기 냉기귀환로(45)를 통해 증발기(25)로 귀환된다.The cold air heat-exchanged with the storage while circulating the inside of the refrigerating compartment 4 as described above is elevated to the upper portion of the refrigerating compartment 40 while the temperature is relatively increased, and is returned to the evaporator 25 through the cold air return path 45. .

이와 같은 냉기의 순환이 이루어지는 본 발명의 냉장고에서는, 상기 팬(50)의 회전에 의해 냉장실(40)로 토출된 냉기가 휘저어지면서 냉기가 정체되지 않고 냉장실(40) 내부를 순환하게 된다. 특히 상기 냉장실(40)의 중간에 부피가 큰 저장물이 놓여지더라도 상기 팬(50)에 의해 냉기가 휘저어지게 되어 냉기의 정체가 발생하지 않으므로, 과냉이나 약냉으로 인한 피해가 발생하지 않게 된다.In the refrigerator of the present invention in which such cold air is circulated, the cold air discharged into the refrigerating compartment 40 by the rotation of the fan 50 is stirred, and the cold air is not stagnant and circulates in the refrigerating compartment 40. In particular, even if a bulky storage is placed in the middle of the refrigerating compartment 40, since the cold air is agitated by the fan 50, congestion of the cold air does not occur, so that damage due to overcooling or weak cooling does not occur.

그리고 이와 같이 냉장실 내부의 냉기를 휘저어줌으로 인해 종래에 약냉각영역이던 도어근처와 냉장실 내벽 둘레의 온도를 상대적으로 낮추어 줄 수 있게 되고, 과냉각영역이던 냉장실의 중앙 후방에 냉기가 정체되는 것을 방지하여 상대적으로 온도를 높여 줄 수 있게 되어 냉장실 전체를 균일하게 냉각할 수 있게 된다.In addition, by stirring the cold air inside the refrigerating compartment, the temperature around the door and the inner wall of the refrigerating compartment, which is a conventional cooling zone, can be relatively lowered. It is possible to raise the temperature relatively, allowing the entire refrigerating compartment to be cooled uniformly.

위에서 상세히 설명한 바와 같은 본 발명에 의한 냉장고의 균일냉각장치는 냉장실로 전달된 냉기가 정체되지 않고 냉장실 내부 구석구석으로 전달되도록 팬을 사용하고 있다. 따라서 상기 팬의 회전에 의해 냉기가 휘저어지면서 한 곳에 정체되지 않고 이동되어 냉장실 전체의 온도가 균일하게 유지될 수 있게 된다.The homogeneous cooling device of the refrigerator according to the present invention as described in detail above uses a fan so that the cold air delivered to the refrigerating compartment is not stagnant and is delivered to every corner of the refrigerating compartment. Therefore, as the cold air is stirred by the rotation of the fan, the cold air is not stagnant and moved, so that the temperature of the entire refrigerating chamber can be maintained uniformly.
