Description

냉장고{Refrigerator}Refrigerator {Refrigerator}

본 고안은 냉장고에 관한 것으로서, 보다 상세하게는 냉기유로의 구조를 개선한 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator having an improved structure of a cold air flow path.

일반적으로 탑마운트 타입의 냉장고(100)는 도 1 및 도 2에 도시된 바와 같이, 상부에 냉동실(115a)을 형성하고 하부에 냉장실(115b)을 형성하는 본체캐비닛(110)과, 냉동실(115a)의 후방영역에 배치되어 냉기를 생성하는 증발기(120)와, 증발기(120)에서 생성된 냉기를 냉동실(115a) 및 냉장실(115b)로 송풍하는 송풍팬(130)과, 송풍팬(130)에 의해 송풍된 냉기를 냉동실(115a) 및 냉장실(115b)로 안내하도록 상호 연통된 냉기유로를 갖는 냉동실덕트(140a) 및 냉장실덕트(140b)와, 냉동실덕트(140a)로부터 냉장실덕트(140b)로 공급되는 냉기를 단속하는 댐퍼(150)를 포함한다. 그리고, 증발기(120)의 주위에는 착상된 성에를 제거하는 제상히터(125)가 장착되어 있다. In general, the top-mounted refrigerator 100 includes a main cabinet 110 and a freezing chamber 115a which form a freezing compartment 115a at an upper portion and a refrigerating chamber 115b at a lower portion thereof, as shown in FIGS. 1 and 2. Disposed in the rear region of the evaporator 120 to generate cold air, a blowing fan 130 to blow the cold air generated by the evaporator 120 to the freezing chamber 115a and the refrigerating chamber 115b, and a blowing fan 130. The freezing chamber duct 140a and the refrigerating chamber duct 140b having the cold air passages communicated with each other to guide the cold air blown by the freezing chamber 115a and the refrigerating chamber 115b, and from the freezing chamber duct 140a to the refrigerating chamber duct 140b. It includes a damper 150 to control the supplied cold air. The defrost heater 125 is installed around the evaporator 120 to remove the frost formed.

냉동실덕트(140a)에는 송풍팬(130)에 의해 송풍된 냉기 중 일부는 냉동실(115a)로 토출하며, 나머지는 냉장실덕트(140b)로 안내하는 냉기유로가 형성되어있다. In the freezing chamber duct 140a, a part of the cold air blown by the blower fan 130 is discharged to the freezing chamber 115a, and a cold air flow path is formed to guide the rest to the refrigerating chamber duct 140b.

제상히터(125)를 구동하는 제상운전을 수행하는 과정에서 증발기(120)의 성에가 녹아 제상수가 발생하게 된다. 이러한 제상수는 냉각운전 수행 시 송풍팬(130)에 의해 송풍되는 냉기에 포함되어 냉동실덕트(140a)로 유입된다.Defrosting of the evaporator 120 melts during the defrosting operation of driving the defrost heater 125 to generate defrost water.

그러나, 이러한 종래의 냉장고(100)는 냉동실덕트(140a)의 냉기유로가 냉장실덕트(140b)로 바로 유입되도록 형성되어 있으므로, 냉각운전 수행 시 냉기에 포함되어 있는 제상수가 댐퍼(150)에 접촉하여 성에로 착상된다. 이렇게 착상된 성에로 인해 댐퍼(150)의 작동불량이 발생할 우려가 있다.However, since the refrigerator 100 is formed such that the cold air flow path of the freezing chamber duct 140a flows directly into the refrigerating chamber duct 140b, the defrost water contained in the cold air contacts the damper 150 when the cooling operation is performed. It is conceived as frost. Due to the frost formed in this way there is a risk that the malfunction of the damper 150 occurs.

냉장실덕트(40b)의 냉기유로는 냉동실덕트(40a)의 냉기유로와 연통되어 있다. 여기서, 냉장실덕트(40b)의 상부영역에는 댐퍼(50)가 마련되어 있다.The cold air flow path of the refrigerating chamber duct 40b communicates with the cold air flow path of the freezing chamber duct 40a. Here, the damper 50 is provided in the upper region of the refrigerating chamber duct 40b.

댐퍼(50)는 냉장실덕트(40b)의 냉기유로상에 마련되어, 냉동실덕트(40a)의 냉기배출부(47b)를 통하여 배출되는 냉기가 냉장실(15b)로 공급되는 것을 단속한 다. 댐퍼(50)는 냉장실덕트(40b)의 냉기유로상에 회동 가능하게 장착되어 냉기유로를 개방하는 개방위치(A)와 냉기유로를 폐쇄하는 폐쇄위치(B) 사이를 이동한다. 댐퍼(50)는 냉장실 냉각운전을 수행하는 경우, 개방위치(A)로 이동하여 냉동실덕트(40a)의 냉기유로와 냉장실덕트(40b)의 냉기유로를 상호 연통시킨다. 그리고, 댐퍼(50)는 냉장실(15b)을 냉각운전을 수행하지 않는 경우, 폐쇄위치(B)로 이동하여 냉동실덕트(40a)의 냉기유로와 냉장실덕트(40b)의 냉기유로 사이를 차단한다.The damper 50 is provided on the cold air flow path of the refrigerating chamber duct 40b to control the supply of cold air discharged through the cold air discharge portion 47b of the freezing chamber duct 40a to the refrigerating chamber 15b. The damper 50 is rotatably mounted on the cold air flow path of the refrigerating chamber duct 40b to move between an open position A for opening the cold air flow path and a closed position B for closing the cold air flow path. When the damper 50 performs the refrigerating compartment cooling operation, the damper 50 moves to the open position A to communicate the cold air passage of the freezing chamber duct 40a with the cold air passage of the refrigerating chamber duct 40b. And, when the damper 50 does not perform the cooling operation of the refrigerating chamber 15b, the damper 50 moves to the closed position B to cut off between the cold air passage of the freezing chamber duct 40a and the cold air passage of the refrigerating chamber duct 40b.

이하에서는 본 고안에 따른 냉장고(1)의 작동과정을 자세히 설명한다.Hereinafter, the operation process of the refrigerator 1 according to the present invention will be described in detail.

증발기(20)에 생성된 성에를 제거하기 위하여 제상히터(25)를 구동하여 제상운전을 수행한다. In order to remove the frost generated in the evaporator 20, the defrosting heater 25 is driven to perform defrosting operation.

제상히터(25)에서 발생하는 열에 의하여 증발기(20)에 착상된 성에가 제거되면서 제상수가 발생하게 된다.Defrost water formed on the evaporator 20 is removed by the heat generated from the defrost heater 25 to generate defrost water.

제상운전을 수행하고 냉동실(15a)과 냉장실(15b)을 모두 냉각운전하는 경우, 댐퍼(50)는 개방위치(A)로 이동하며 송풍팬(30)은 구동된다. 여기서, 증발기(20)에서 생성된 냉기는 송풍팬(30)에 의해 냉동실덕트(40a)의 냉기유로로 유입된다. 냉동실덕트(40a)로 유입된 냉기에는 제상수가 포함되어 있다.When the defrosting operation is performed and both the freezing chamber 15a and the refrigerating chamber 15b are cooled, the damper 50 moves to the open position A and the blower fan 30 is driven. Here, the cold air generated by the evaporator 20 is introduced into the cold air flow path of the freezing chamber duct 40a by the blowing fan 30. The cold air introduced into the freezing chamber duct 40a includes defrost water.

냉기 중 일부는 냉동실덕트(40a)의 냉기유로를 따라 이동하면서 냉동실(15a)로 토출되며, 나머지는 냉장실덕트(40b)의 냉기유로로 유입되어 냉장실(15b)로 토출된다. 여기서, 냉기에 포함되어 있는 제상수는 냉동실덕트(40a)의 만곡부(48)를 지나면서 만곡부(48)에 모이게 된다. 이에, 냉장실덕트(40b)로 유입되는 냉기에는 제상수가 포함되지 않아 냉각운전 수행시 댐퍼(50)가 어는 것을 방지할 수 있게 된 다. 그리고, 만곡부(48)에 모인 제상수는 배수부(49)를 통하여 다시 증발기로 배출된다. 이에, 만곡부(48)에서 제상수가 어는 것을 방지할 수 있게 된다.Some of the cold air is discharged to the freezing compartment 15a while moving along the cold air passage of the freezing chamber duct 40a, and the other is introduced into the cold air passage of the refrigeration chamber duct 40b and discharged to the refrigerating chamber 15b. Here, the defrost water contained in the cold air is collected in the curved portion 48 while passing through the curved portion 48 of the freezing chamber duct 40a. Therefore, since the defrost water is not included in the cold air introduced into the refrigerating chamber duct 40b, the damper 50 may be prevented from freezing when the cooling operation is performed. The defrost water collected at the curved portion 48 is discharged again to the evaporator through the drain 49. As a result, the defrosting water in the curved portion 48 can be prevented from freezing.

한편, 제상운전을 수행하고 냉동실(15a)만을 냉각운전하는 경우, 댐퍼(50)는 폐쇄위치(B)로 이동하며, 전술한 바와 마찬가지로 댐퍼(50)에 접촉되는 냉기에는 제상수가 포함되어 있지 않으므로 냉각운전 수행시 댐퍼(50)가 어는 것을 방지할 수 있게 된다.On the other hand, when the defrosting operation is performed and only the freezing chamber 15a is cooled, the damper 50 moves to the closed position B. As described above, the cold air contacting the damper 50 does not include the defrosting water. Therefore, it is possible to prevent the damper 50 from freezing when performing the cooling operation.
