본 발명은, 냉장고에 관한 것으로서, 보다 상세하게는, 냉기덕트에 구조를 개선하여 배플의 오작동을 방지할 수 있는 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of preventing malfunction of a baffle by improving a structure in a cold air duct.

냉장고는 압축기, 응축기, 모세관을 거친 냉매가 기화하면서 냉기를 발생시키는 증발기를 갖는다. 증발기에서 발생된 냉기는 냉기유로가 형성된 냉기덕트로 유동하여 저장실로 공급된다. 그리고, 냉기덕트에는 저장실의 온도를 조절하기 위해 냉기의 유량을 조절하도록 냉기유로를 개방 및 폐쇄하는 댐퍼가 마련되어 있다.The refrigerator has an compressor, a condenser, and an evaporator which generates cold air while the refrigerant passing through the capillary vaporizes. The cold air generated in the evaporator flows into the cold air duct in which the cold air flow path is formed and is supplied to the storage compartment. The cold air duct is provided with a damper that opens and closes the cold air flow path to control the flow rate of the cold air in order to control the temperature of the storage compartment.

한편, 종래의 냉장고는 증발기에서 발생되는 냉기가 저장실로 공급되도록 냉기가 유동하는 냉기유로를 개폐 및 폐쇄하는 배플과, 배플이 개방위치와 폐쇄위치 사이에서 작동가능하게 하는 배플구동부를 포함하고 있다.On the other hand, the conventional refrigerator includes a baffle for opening and closing a cold air flow path in which cold air flows so that cold air generated in the evaporator is supplied to the storage compartment, and a baffle driving part for enabling the baffle to operate between an open position and a closed position.

그러나, 종래의 냉장고는 도어개폐로 인해 외부 공기가 저장실 내로 유입되어 응결수가 생길 수 있으며, 응결수의 결빙으로 인해 주기적인 제상작업으로 인해 제상수가 발생한다. 응결수 및 제상수는 배플을 구동시키는 배플구동부에 유입되어 결빙될 수 있다. 따라서, 배플구동부에 유입된 응결수 및 제상수와 같은 물이 결빙되면 배플의 작동이 원활하지 않아 사용자가 원하는 저장실 온도를 유지할 수 없다는 문제점이 있다.However, in the conventional refrigerator, condensation water may be generated due to the introduction of external air into the storage compartment due to the opening and closing of the door, and defrost water is generated due to periodic defrosting operations due to the freezing of the condensation water. The condensed water and the defrost water may flow into the baffle driving unit that drives the baffle and freeze. Therefore, when water such as condensed water and defrost water introduced into the baffle drive unit freezes, there is a problem in that the operation of the baffle is not smooth and the user cannot maintain a desired storage temperature.

따라서, 본 발명의 목적은, 배플구동부에 물이 유입되어 결빙이 되는 것을 방지하고, 이에 따라 배플의 작동을 원활히 하여, 저장실 내의 온도 유지를 할 수 있는 냉장고를 제공하는 것이다.Accordingly, an object of the present invention is to provide a refrigerator capable of preventing water from flowing into the baffle driving unit and freezing, thereby smoothing the operation of the baffle and maintaining the temperature in the storage compartment.

상기 목적은, 본 발명에 따라, 증발기와, 상기 증발기에서 발생된 냉기가 유 동하는 냉기유로가 형성된 냉기덕트를 갖는 냉장고에 있어서, 상기 냉기덕트는, 상기 증발기에서 발생된 냉기가 유입 및 유출되는 유입구 및 유출구를 형성하는 댐퍼케이싱과; 상기 유입구 및 유출구 중 적어도 어느 하나에 마련되어, 상기 냉기유로를 유동하는 냉기의 유량을 조절하도록 개폐하는 배플과; 상기 댐퍼케이싱에 마련되어, 상기 댐퍼배플을 개방위치와 폐쇄위치로 구동시키는 배플구동부와; 상기 배플과 상기 배플구동부 사이에 마련되어, 상기 배플로부터 발생된 낙수를 상기 댐퍼케이싱의 하부로 안내하는 가이드부를 포함할 수 있다.The object of the present invention is a refrigerator having an evaporator and a cold air duct in which a cold air flow path through which cold air generated in the evaporator flows is formed, wherein the cold air duct is configured to allow the cold air generated in the evaporator to flow in and out. A damper casing forming an inlet and an outlet; A baffle provided in at least one of the inlet and the outlet, and configured to open and close to control a flow rate of cold air flowing through the cold air passage; A baffle driving part provided in the damper casing to drive the damper baffle to an open position and a closed position; It may be provided between the baffle and the baffle driving portion, and may include a guide portion for guiding the falling water generated from the baffle to the bottom of the damper casing.

여기서, 상기 가이드부는 중앙부가 볼록한 형상을 가질 수 있다.Here, the guide portion may have a shape in which the central portion is convex.

상기 가이드부의 외표면에는 상기 댐퍼케이싱의 하부로 낙수의 유동을 안내하는 그루부가 형성될 수 있다.The outer surface of the guide portion may be formed with a groove for guiding the flow of falling water to the lower portion of the damper casing.

냉장고(1)가 작동되면 압축기(미도시), 응축기(미도시), 모세관(미도시)을 거친 냉매는 증발기에서 기화하면서 냉기를 발생시킨다. 증발기에서 발생된 냉기는 냉기덕트(10)로 유동되어 저장실(6)로 공급된다. 이때, 냉기는 냉기덕트(10)에 설치된 댐퍼케이싱(11)의 유입구(12)로 유입되어 댐퍼케이싱(11)의 유출구(13)로 유출되면서 저장실(6)로 냉기를 안내하는 저장실냉기유로로 유동한다. 댐퍼케이싱(11)의 유출구(13)에는 저장실(6) 내에 마련된 써모감지부(7)에 의해 감지된 온도에 기초하여 냉기를 유동 및 차단시키는 배플(14)이 마련되며, 배플(14)의 하부에는 배플(14)을 개방위치와 폐쇄위치 사이에서 구동시키도록 배플구동부(20)가 마련되어 있다. 배플(14)과 배플구동부(20) 사이에는 돌출된 가이드부(15)가 있다. 사용자가 도어(4)를 개방함으로써, 저장실(6) 내로 유입되는 외부공기로 인해 응결수가 발생하며, 응결수가 결빙되면 제상 작업을 거쳐 제상수가 발생되게 된다. 그러면, 댐퍼케이싱(11)에 맺힌 응결수 및 제상수와 같은 물이 배플구동부(20)가 마련된 하부로 낙하하며, 배플(14)과 배플구동부(20) 사이에 개재된 가이드부(15)는 낙하하는 물이 배플구동부(20)로 유입되지 않도록 댐퍼케이싱(11)의 양측부로 안내한다.When the refrigerator 1 is operated, the refrigerant passing through the compressor (not shown), the condenser (not shown), and the capillary tube (not shown) generates cold air while vaporizing in the evaporator. The cold air generated in the evaporator flows into the cold air duct 10 and is supplied to the storage chamber 6. At this time, the cold air flows into the inlet 12 of the damper casing 11 installed in the cold air duct 10 and flows out of the outlet 13 of the damper casing 11 to guide the cold air to the storage compartment 6. Flow. The outlet 13 of the damper casing 11 is provided with a baffle 14 for flowing and blocking cold air based on the temperature sensed by the thermo-sensing unit 7 provided in the storage chamber 6. In the lower part, a baffle driving part 20 is provided to drive the baffle 14 between the open position and the closed position. Between the baffle 14 and the baffle driving part 20 is a protruding guide portion 15. When the user opens the door 4, condensation water is generated due to external air flowing into the storage compartment 6, and when the condensation water is frozen, defrosting water is generated through defrosting. Then, water, such as condensed water and defrost water, formed in the damper casing 11 falls to the lower part provided with the baffle driver 20, and the guide part 15 interposed between the baffle 14 and the baffle driver 20 is The falling water is guided to both sides of the damper casing 11 so that the water does not flow into the baffle drive unit 20.

이에, 배플구동부에 물이 유입되어 결빙이 되는 것을 방지함으로써, 배플의 작동을 원활히 하여 저장실 내의 온도 유지를 할 수 있다.Accordingly, by preventing water from flowing into the baffle drive unit to freeze, the operation of the baffle can be smoothed to maintain the temperature in the storage compartment.

이상 설명한 바와 같이, 본 발명에 따르면, 배플구동부에 물이 유입되어 결빙이 되는 것을 방지하고, 배플의 작동을 원활히 하여, 저장실 내의 온도 유지를 할 수 있는 냉장고가 제공된다.As described above, according to the present invention, a refrigerator is provided which prevents water from flowing into the baffle drive unit and freezes, smoothes the operation of the baffle, and maintains the temperature in the storage compartment.
