Description

냉기분배장치를 갖는 냉장고Refrigerator with cold air distributor

본 발명은, 냉각실을 갖는 냉장고에 관한 것이다.The present invention relates to a refrigerator having a cooling chamber.

냉기분배장치를 갖는 냉장고는, 본 출원인에 의해 PCT출원된 다양한 형태의 구성을 가지는 것들이 기 출원되어 있다. 종래의 냉기분배장치를 갖는 냉장고는, 거의 직사각형상의 본체내에 중간격벽에 의해 냉동실과 냉장실로 구분된 한 쌍의 냉각실이 마련되어 있으며, 각 냉각실의 개구 전면에는 개폐용도어가 각각 설치되어 있다.Refrigerators having a cold air distribution device have been previously applied to those having various types of configurations filed by the present applicant. In a conventional refrigerator having a cold air distribution device, a pair of cooling chambers divided into a freezer compartment and a refrigerating chamber by an intermediate partition in a substantially rectangular main body are provided, and opening and closing doors are respectively provided on the front surface of each opening of each cooling chamber.

본체내에는 압축기와 도시않은 응축기 및 냉동실증발기와 냉장실증발기로 이루어진 냉동시스템이 설치되어 있다. 각 증발기에서 생성된 냉기는 냉동실팬 혹은 냉장실팬에 의해 각 냉각실로 공급된다. 냉장실의 후방벽 내에는, 냉장실증발기로 부터의 냉기가 냉장실팬에 의해 송풍되어 유동하는 냉기덕트가 마련되어 있고, 이 냉기덕트 내에는 냉기분배장치가 상하방향으로 설치되어 있다. 냉장실의 후벽면에는 냉기덕트로부터의 냉기가 냉장실로 토출되는 냉기토출구가 형성되어 있고, 냉기분배장치는 공급된 냉기를 안내하여 냉기토출구를 통해 냉장실에 공급한다. 냉기덕트의 후방에는 냉장실과 냉장실증발기를 연결하는 순환덕트가 냉기덕트에 대해 격리되도록 형성되어 있다. 이렇게 냉장실을 냉각시킨 냉기는 이 순환덕트를 통해 냉장실증발기로 되돌아간다.In the main body, a refrigeration system consisting of a compressor, a condenser (not shown), a freezer compartment evaporator and a refrigerator compartment evaporator is installed. The cold air generated in each evaporator is supplied to each cooling chamber by a freezer compartment fan or a refrigerator compartment fan. In the rear wall of the refrigerating chamber, there is provided a cold air duct in which cold air from the refrigerating chamber evaporator is blown by the refrigerating chamber fan, and the cold air duct is provided in the vertical direction. On the rear wall of the refrigerating chamber, a cold air discharge port through which cold air from the cold air duct is discharged to the refrigerating chamber is formed, and the cold air distribution device guides the supplied cold air to the cold room through the cold air discharge port. At the rear of the cold air duct, a circulation duct connecting the refrigerator compartment and the refrigerator compartment evaporator is formed to be isolated from the cold air duct. The cold air cooling the refrigerating compartment is returned to the refrigerating chamber evaporator through the circulation duct.

그런데, 이러한 냉기분배장치를 갖는 종래의 냉장고에서는, 냉기분배장치의 구조가 복잡하여 제작에 어려움이 있고, 제작단가가 상승한다는 문제점이 있다. 또한, 종래의 냉기분배장치는, 냉각실내에 급속한 냉각을 필요로 하는 식품이 유입되는 경우 집중적으로 냉기를 공급할 수 없어 급속하게 냉각을 실현하는 것이 어렵고, 과도한 냉각으로 인해 손상이 우려되는 식품이 유입되는 경우 냉기의 공급방향을 사용자의 임의대로 제어할 수 없어 효과적인 냉각을 실현하는 것이 어렵다는 단점이 있다.By the way, in the conventional refrigerator having such a cold air distribution device, the structure of the cold air distribution device is complicated, there is a difficulty in manufacturing, there is a problem that the manufacturing cost increases. In addition, in the conventional cold air distribution device, when food requiring rapid cooling flows into the cooling chamber, it is difficult to supply cold air intensively, and thus, it is difficult to realize rapid cooling, and foods that may be damaged due to excessive cooling are introduced. In this case, since the supply direction of the cold air cannot be arbitrarily controlled by the user, it is difficult to realize effective cooling.

따라서, 본 발명의 목적은, 종래의 이러한 문제점들을 고려하여, 제작이 용이한 비교적 간단한 구조의 냉기분배장치를 제공할 수 있고, 냉기덕트로부터 토출되는 냉기의 공급방향을 사용자의 임의대로 조절할 수 있는 냉기분배장치를 갖는 냉장고를 제공하는 것이다.Accordingly, an object of the present invention, in consideration of these problems in the prior art, can provide a cold air distribution device having a relatively simple structure that is easy to manufacture, it is possible to adjust the supply direction of the cold air discharged from the cold air duct at the user's discretion It is to provide a refrigerator having a cold air distribution device.

회동조작노브(17)의 회전운동은, 수용슬롯(16a)에 수용된 편심축(20)에 의하여 지지바(14)의 왕복운동으로 바뀌며 이와 같이 회전운동이 왕복우동으로 바뀌게 되어 좌우분배날개(10)를 좌우회동시켜 냉기를 원활하게 공급한다.The rotational movement of the rotation control knob 17 is changed to the reciprocating motion of the support bar 14 by the eccentric shaft 20 accommodated in the accommodation slot 16a, and thus the rotational motion is changed to the reciprocating motion so that the left and right distribution wings 10 ) Rotate left and right to supply cold air smoothly.

도 4 내지 도 6에 도시한 바와 같이, 본 냉기분배장치(30)는, 사용자의 임의대로 회동조작노브(17)를 좌우조절함으로써, 덕트커버(21)의 길이방향을 따라 형성된 냉기토출구(9) 후방에 마련된 좌우분배날기(10)의 방향을 자유롭게 조절할 수 있으며, 이로 인하여, 증발기로부터 생성되는 냉기의 공급방향을 사용자의 임의대로 원하는 방향이나 집중냉각을 필요로 하는 식품을 향하여 조절할 수 있다.As shown in Figs. 4 to 6, the present cold air distribution device 30, by adjusting the rotation operation knob 17 to the left and right of the user arbitrarily, the cold air discharge port 9 formed along the longitudinal direction of the duct cover 21 ) The direction of the left and right distribution wings 10 provided at the rear side can be freely adjusted, and thus, the supply direction of the cold air generated from the evaporator can be adjusted toward the food requiring the desired direction or the concentrated cooling as desired by the user.

상술 및 도시한 실시 예에서는 설명의 용이함을 위하여, 좌우분배날개의 하부에 연동부재와, 회동조작노브가 설치되는 것에 대하여 설명하였지만, 좌우분배날개의 상부에 연동부재와, 회동조작노브가 설치되는 것에도 상기와 마찬가지의 냉기분배장치를 설치하여 상술한 동일한 목적을 달성할 수 있다.In the above-described and illustrated embodiments, the interlocking member and the pivoting knob are installed below the left and right distribution vanes for ease of explanation. However, the interlocking member and the pivoting knob are installed on the upper and left distribution blades. The same object as described above can be achieved by providing the same cold air distribution device as above.

또한, 전술 및 실시예에서는, 냉기분배장치가 냉장실에 설치되어 있는 것에 대하여 설명하였지만 냉동실에도 상술한 바와 같은 냉기분배장치를 설치할 수 있음은 물론이다.In addition, although the above-mentioned and the Example demonstrated that the cold air distribution apparatus is installed in the refrigerating chamber, the cold air distribution apparatus as mentioned above can also be installed also in a freezer compartment.

이상에서 설명한 바와 같이, 본 발명에 따르면, 제작이 용이한 비교적 간단한 구조의 냉기분배장치를 제공할 수 있고, 집중냉각이 필요한 식품이나 과도한 냉각으로 냉기를 차단할 필요가 있는 식품이 유입되는 경우 냉기덕트로부터 토출되는 냉기의 공급방향을 사용자의 임의대로 조절할 수 있는 냉기분재장치를 갖는 냉장고가 제공된다.As described above, according to the present invention, it is possible to provide a cold air distribution device having a relatively simple structure that is easy to manufacture, and when a food requiring intensive cooling or a food that needs to block cold air due to excessive cooling is introduced into the cold air duct There is provided a refrigerator having a cold air bonsai apparatus that can arbitrarily adjust a supply direction of cold air discharged from the user.
