본 발명은, 냉장고에 관한 것으로서, 보다 상세하게는, 덕트부재의 구조를 개선한 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator having an improved structure of a duct member.

일반적으로, 냉장고는 냉동사이클을 통해 제공되는 냉기를 저장실로 공급하여 저장실 내의 식품을 장기간 신선하게 유지시킬 수 있는 장치이다. 냉장고는 저장실을 형성하는 본체캐비닛과, 저장실에 공급되는 냉기를 생성하는 증발기와, 증발기에서 생성된 냉기를 저장실로 공급하는 송풍팬과, 증발기를 커버하여 저장실과 증발기 사이를 유동하는 냉기의 유로를 형성하는 덕트부재를 포함한다.In general, a refrigerator is a device capable of supplying cold air provided through a refrigeration cycle to a storage compartment to keep food in the storage compartment fresh for a long time. The refrigerator includes a main cabinet forming a storage compartment, an evaporator for generating cold air supplied to the storage compartment, a blower fan for supplying cold air generated from the evaporator to the storage compartment, and a flow path of cold air flowing between the storage compartment and the evaporator by covering the evaporator. It includes a duct member to form.

덕트부재에는 송풍팬이 장착되는 송풍팬장착부가 형성되어 있으며, 발포성 단열재질로 마련된다. The duct member is provided with a blowing fan mounting portion to which the blowing fan is mounted, and is provided with a foamable insulating material.

그러나, 이러한 종래의 냉장고는 증발기와 저장실 사이의 온도차에 의하여 덕트부재 주위에 수분이 발생하게 된다. 이러한 수분은 발포성 단열재질로 마련되는 덕트부재에 침투하여 송풍팬장착부를 변형시킨다. 이러한 송풍팬장착부의 변형은 송풍팬의 회전에 간섭되어 저장실의 냉각성능을 저하시키는 문제점이 있다. However, in the conventional refrigerator, moisture is generated around the duct member due to the temperature difference between the evaporator and the storage compartment. This moisture penetrates into the duct member provided with a foamable insulating material to deform the blower fan mounting portion. Such a deformation of the blower fan mounting part may interfere with the rotation of the blower fan, thereby degrading the cooling performance of the storage compartment.

따라서, 본 발명의 목적은, 수분침투에 의한 덕트부재의 변형을 방지하여 송풍팬의 작동 신뢰성을 향상시킴으로써, 저장실의 냉각성능을 향상시킬 수 있는 냉장고를 제공하는 것이다. Accordingly, an object of the present invention is to provide a refrigerator capable of improving the cooling performance of a storage compartment by preventing deformation of the duct member due to water penetration and improving the operational reliability of the blower fan.

A blowing fan mounting portion to which the blowing fan is mounted is formed, and a duct member of a foamable insulating material covering the evaporator; It is achieved by a refrigerator including at least one region of the duct member to cover the at least one area to block moisture from penetrating the duct member.

상기 수분차단커버는 상기 송풍팬장착부를 커버하는 송풍팬커버를 포함하는 것이 바람직하다.The moisture barrier cover preferably includes a blower fan cover covering the blower fan mounting portion.

상기 송풍팬커버는 상기 덕트부재의 발포시 인서트 성형되는 것이 바람직하다.The blowing fan cover is preferably insert molded when the duct member is foamed.

상기 덕트부재에는 상기 송풍팬장착부에 인접하게 냉기유로가 형성되어 있으며; 상기 수분차단커버는 상기 송풍팬장착부와 상기 냉기유로의 경계영역을 커버하는 경계영역커버를 포함하는 것이 바람직하다.The duct member is formed with a cold air flow passage adjacent to the blowing fan mounting portion; The moisture barrier cover preferably includes a boundary region cover covering a boundary region between the blower fan mounting portion and the cold air flow path.

상기 경계영역커버는 상기 덕트부재에 착탈 가능하게 결합되는 것이 바람직하다.The boundary area cover is preferably detachably coupled to the duct member.

However, the boundary region cover 63 may be insert molded during the foam molding of the duct body 51. As a result, it is possible to prevent the moisture from penetrating the deformation of the partition wall 55 to improve driving reliability of the blower fan 40.

본 발명에 따른 냉장고(1)의 수분차단커버(60)는 냉동실에 배치되는 덕트부재(50)에 마련될 수도 있지만, 증발기수용부(17)와 저장실(15)의 온도차가 커 수분 이 많이 발생하는 냉장실에 배치되는 덕트부재(50)에 마련되는 것이 더욱 효과적이다.The moisture blocking cover 60 of the refrigerator 1 according to the present invention may be provided in the duct member 50 disposed in the freezer compartment, but a large amount of moisture is generated due to a large temperature difference between the evaporator accommodating portion 17 and the storage compartment 15. It is more effective to be provided in the duct member 50 disposed in the refrigerating chamber.

한편, 본 발명에 따른 냉장고(1)의 수분차단커버(60)는 송풍팬커버(61)와 경계영역커버(63) 모두를 포함하는 것으로 설명하고 도시하였으나, 이에 한정되지 않고 송풍팬커버(61)와 경계영역커버(63) 중 어느 하나를 제거할 수도 있다.Meanwhile, although the moisture blocking cover 60 of the refrigerator 1 according to the present invention has been described and illustrated as including both the blower fan cover 61 and the boundary area cover 63, the blower fan cover 61 is not limited thereto. ) And the boundary area cover 63 may be removed.

이러한 구성에 의해 본 발명에 따른 냉장고(1)의 냉기의 유동과정을 살펴보면 다음과 같다.Looking at the flow of the cold air of the refrigerator 1 according to the present invention by such a configuration as follows.

우선, 송풍팬(40)이 구동되면 저장실(15)의 냉기가 냉기유입구(58)를 통하여 증발기수용부(17)로 유입된다. 증발기수용부(17)로 유입된 냉기는 증발기(30)와 열교환하여 냉각된다. 증발기(30)에서 생성된 냉기는 송풍팬(40)의 구동에 의하여 송풍팬장착부(53)를 거쳐 메인유로(52a)를 통과하여 냉기토출구(59)로 토출된다. 한편, 증발기(30)에서 생성된 냉기는 송풍팬(40)의 구동에 의하여 송풍팬장착부(53)를 거쳐 서브유로(52b)를 통하여 보조저장실(25)로 토출된다. First, when the blower fan 40 is driven, cold air of the storage chamber 15 flows into the evaporator accommodating part 17 through the cold air inlet 58. The cold air introduced into the evaporator accommodating part 17 is cooled by heat exchange with the evaporator 30. The cold air generated by the evaporator 30 is discharged to the cold air discharge port 59 through the blower fan mounting part 53 through the main flow path 52a by driving the blower fan 40. On the other hand, the cold air generated by the evaporator 30 is discharged to the auxiliary storage chamber 25 through the sub-channel 52b through the blower fan mounting portion 53 by driving the blower fan 40.

여기서, 저장실(15)과 증발기수용부(17) 사이의 온도차에 의하여 수분이 발생할 수 있는데, 송풍팬장착부(53)가 송풍팬커버(61)에 의하여 차단되어 있으므로 수분이 송풍팬장착부(53)에 침투하지 못하게 된다. 이에, 송풍팬장착부(53)의 변형을 방지하여 송풍팬(40)의 구동 신뢰성을 향상시키며, 나아가서는 저장실(15)의 냉각효율을 향상시킬 수 있게 된다. Here, moisture may be generated due to a temperature difference between the storage chamber 15 and the evaporator accommodating part 17. Since the blowing fan mounting part 53 is blocked by the blowing fan cover 61, the moisture is blown fan mounting part 53. Will not penetrate the. Accordingly, the deformation of the blower fan mounting part 53 is prevented, thereby improving the driving reliability of the blower fan 40, and further, the cooling efficiency of the storage chamber 15 can be improved.

또한, 송풍팬장착부(53)와 서브유로(52b) 사이의 구획벽(55)은 경계영역커버(63)에 의하여 차단되어 있으므로 수분이 구획벽(55)에 침투하지 못하게 된다. 이에, 구획벽(55)의 변형을 방지하여 송풍팬(40)의 구동 신뢰성을 향상시키며, 나아가서는 저장실(15)의 냉각효율을 향상시킬 수 있게 된다.In addition, since the partition wall 55 between the blower fan mounting portion 53 and the sub flow passage 52b is blocked by the boundary region cover 63, moisture does not penetrate the partition wall 55. Accordingly, the deformation of the partition wall 55 is prevented, thereby improving the driving reliability of the blower fan 40, and further, the cooling efficiency of the storage compartment 15 can be improved.

이상에서 설명한 바와 같이, 본 발명은 덕트부재(50)의 적어도 일영역을 커버하여 덕트부재(50)에 수분이 침투하는 것을 차단하는 수분차단커버(60)를 마련함으로써, 수분침투에 의한 덕트부재(50)의 변형을 방지하여 송풍팬(40)의 작동 신뢰성을 향상시킴으로써, 저장실(15)의 냉각성능을 향상시킬 수 있게 된다.As described above, the present invention covers the at least one region of the duct member 50 to provide a moisture barrier cover 60 to block the penetration of moisture into the duct member 50, thereby the duct member due to moisture penetration It is possible to improve the cooling performance of the storage chamber 15 by preventing the deformation of the 50 to improve the operational reliability of the blower fan 40.

이상 설명한 바와 같이, 본 발명에 따르면, 수분침투에 의한 덕트부재의 변형을 방지하여 송풍팬의 작동 신뢰성을 향상시킴으로써, 저장실의 냉각성능을 향상시킬 수 있는 냉장고를 제공할 수 있다.As described above, according to the present invention, it is possible to provide a refrigerator capable of improving the cooling performance of the storage compartment by preventing the deformation of the duct member due to moisture penetration and improving the operating reliability of the blowing fan.
