저장실(300)은 후면부(370) 상부에 냉기가 몸체(100) 전방을 향하도록 토출되는 제2냉기토출구(320)를 형성한다.The storage chamber 300 forms a second cold air discharge port 320 on the rear portion 370 to discharge cold air toward the front of the body 100.

저장실(300)의 상면부(360) 전방에는 냉기가 하강하도록 토출되는 제1냉기토출구(310)가 저장실(300)의 전방에 치우쳐서 형성된다.In front of the upper surface portion 360 of the storage chamber 300, the first cold air discharge port 310 discharged so that cold air descends is formed to be inclined in front of the storage chamber 300.

도2는 본 발명의 바람직한 실시예에 따른 몸체(100)의 단면도이다.2 is a cross-sectional view of the body 100 according to a preferred embodiment of the present invention.

저장실(300)은 도어(200)가 닫혀서 밀폐된다.The storage chamber 300 is closed by the door 200 being closed.

몸체(100)는 상부에 제3공간(630)을 마련한다.The body 100 provides a third space 630 at an upper portion thereof.

팬(400)은 몸체(100) 상부의 제3공간(630)에 마련되는데, 도2처럼 몸체(100)의 중심으로부터 전면부쪽으로 치우쳐서 형성된다.The fan 400 is provided in the third space 630 above the body 100, and is formed by biasing toward the front part from the center of the body 100 as shown in FIG. 2.

팬(400)은 냉기를 이송시키는데 횡류를 일으키는 것으로 형성되는 것이 바람직하다.The fan 400 is preferably formed to cause cross flow to transport cold air.

덕트(600)는 저장실(300)의 상면에 형성되는 제1공간(610)과 저장실(300)의 후면에 형성되는 제2공간(620)에 걸쳐 형성되고, 제1공간(610)과 제2공간(620)은 서로 연결되어 유로를 형성한다.The duct 600 is formed over the first space 610 formed on the upper surface of the storage chamber 300 and the second space 620 formed on the rear surface of the storage chamber 300, and the first space 610 and the second space. The spaces 620 are connected to each other to form a flow path.

제1토출구는 저장실(300)의 후면 상단에 형성되어 제2공간(620)과 관통된다.The first discharge port is formed at an upper end of the rear surface of the storage chamber 300 and penetrates the second space 620.

제2토출구는 저장실(300)의 상면에서 몸체(100) 전방에 배치되면서 형성되어 제1공간(610)과 관통된다.The second discharge port is formed while being disposed in front of the body 100 on the upper surface of the storage chamber 300 to penetrate the first space 610.

댐퍼(500)는 팬(400) 아래에 위치하면서 격벽(700)에 힌지(510)결합으로 형성되는데 스프링(미도시)에 의한 복원력을 가도록 형성되어 격벽(700)에 형성된 개폐구(340)를 개폐할 수 있도록 형성된다.The damper 500 is formed under the fan 400 and is formed by a hinge 510 coupled to the partition wall 700. The damper 500 is formed to have a restoring force by a spring (not shown) to open and close the opening and closing opening 340 formed in the partition wall 700. It is formed to be.

팬(400)이 작동하면 이송되는 냉기에 의해 댐퍼(500)가 스프링(미도시)의 탄성력을 극복하면서 개폐구(340)를 개방한다.When the fan 400 operates, the damper 500 opens and closes the opening and closing port 340 while overcoming the elastic force of the spring (not shown) by the cold air transferred.

또한, 냉장고는 댐퍼(500)개폐용 모터(미도시)를 설치하여 모터(미도시)의 작동으로 댐퍼(500)를 움직여서 댐퍼(500)가 격벽(700)에 형성된 개폐구(340)를 개폐할 수 있도록 형성될 수도 있다.In addition, the refrigerator is provided with a damper 500 opening and closing motor (not shown) to move the damper 500 by the operation of the motor (not shown) to open and close the opening and closing port 340 formed in the partition wall 700 of the damper 500. It may be formed to be.

흡입구(330)는 냉기가 저장실로부터 빠져나가 순환될 수 있도록 저장실(300)은 후면의 하단에 형성된다.The suction port 330 is formed at the lower end of the rear surface so that cold air can escape from the storage chamber and circulate.

다음으로 본 발명의 바람직한 실시예를 설명한다.Next, a preferred embodiment of the present invention will be described.

냉장고가 작동하면서 팬(400)이 돌아가면 냉기가 댐퍼(500)를 하부방향으로 밀어내게 되고 댐퍼(500)는 힌지(510)를 중심으로 회전하여 개폐구(340)를 개방시킨다.When the fan 400 rotates while the refrigerator operates, the cold air pushes the damper 500 downward, and the damper 500 rotates around the hinge 510 to open the opening and closing port 340.

또는 앞서 언급하였듯이 모터(미도시)가 댐퍼(500)를 회전시킴으로써 댐퍼(500)는 힌지(510)를 중심으로 회전하여 개폐구(340)를 개방시킬 수도 있다.Alternatively, as mentioned above, the motor (not shown) rotates the damper 500 so that the damper 500 may rotate about the hinge 510 to open the opening and closing port 340.

일부 냉기는 개방된 개폐구(340)를 지나고, 댐퍼(500)에 의하여 방향이 변환된 냉기는 제1공간(610)을 통하여 제2공간(620)으로 형성된 유로를 따라 흐르게 된다.Some of the cold air passes through the open opening and closing port 340, and the cold air whose direction is changed by the damper 500 flows along the flow path formed in the second space 620 through the first space 610.

냉기는 제2냉기토출구(320)로 빠져나와 저장실(300)의 후면부(370)를 냉각시키게 된다.The cold air exits to the second cold air discharge port 320 to cool the rear part 370 of the storage compartment 300.

또한 일부 냉기는 개구부(350)을 지나 제1공간(610)을 통과하여 제1냉기토출구(310)로 빠져나와 저장실(300)의 전면부를 냉각시킨다.In addition, some of the cold air passes through the opening 350 and passes through the first space 610 to exit the first cold air outlet 310 to cool the front part of the storage compartment 300.

제1냉기토출구(310)는 저장실(300)의 전방 상면에 형성되기 때문에 저장실(300)의 전방의 정온성을 향상시켜준다.Since the first cold air discharge port 310 is formed on the front upper surface of the storage chamber 300, the temperature of the front of the storage chamber 300 is improved.

또한 제1냉기토출구(310)가 저장실(300)의 전방 상면에 형성되기 때문에 도어(200)가 열릴 때 냉기가 팬(400)에 의하여 이송되는 힘과 중력에 의한 힘 때문에 저장실(300)의 전면부를 수직하강하게 되면서 에어커튼역할을 수행하기 때문에 저장실(300)의 냉기가 외부로 유실되는 것을 억제하여 저장실(300)의 정온성 향상에 도움을 주게 된다.In addition, since the first cold air discharge port 310 is formed on the front upper surface of the storage compartment 300, the front surface of the storage compartment 300 due to the force of gravity and the force of the cold air being transferred by the fan 400 when the door 200 is opened. Since the portion is vertically lowered to serve as an air curtain, it is helpful to improve the quietness of the storage compartment 300 by suppressing the loss of cold air from the storage compartment 300 to the outside.

저장실(300)은 후면 하단에 냉기가 제3공간(630)으로 흘러가도록 흡입구(330)를 형성한다.The storage chamber 300 forms a suction port 330 at a lower end of the rear surface so that the cool air flows into the third space 630.

제2냉기토출구(320)와 제1냉기토출구(310)를 통해서 저장실(300)로 유입된 냉기는 저장물을 냉각시킨 후 흡입구(330)를 통해 제3공간(630)으로 빠져나간다.The cold air introduced into the storage chamber 300 through the second cold air discharge port 320 and the first cold air discharge port 310 cools the storage and exits to the third space 630 through the suction port 330.

냉기는 제3공간(630)에서 다시 팬(400)으로 보내지고 위에서 언급한 일련의 과정들이 반복되면서 순환하여 저장실(300)은 정온성을 유지할 수 있게 된다.The cold air is sent back to the fan 400 in the third space 630 and the series of processes described above are repeated to circulate, thereby allowing the storage room 300 to maintain a constant temperature.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 됨을 부언한다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims.
