Description
본 발명은 냉각실을 형성하는 캐비넷과, 상기 냉각실의 측벽내에 마련되어 냉기통로를 형성하며 상기 냉각실의 내부를 향해 개구된 적어도 하나의 냉기토출구를 갖는 덕트를 갖는 냉장고에 관한 것으로서, 특히, 냉각실내에 냉기를 균일하게 분배하기 위한 냉기분배장치를 갖는 냉장고에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a cabinet forming a cooling chamber and a duct having a cold air passage provided in a side wall of the cooling chamber and having a cold air outlet opening toward the interior of the cooling chamber. The present invention relates to a refrigerator having a cold air distribution device for uniformly distributing cold air in a room.
냉장고는 일반적으로, 중간격벽에 의해 구획된 한 쌍의 냉각실 즉 냉동실과 냉장실을 형성하는 캐비넷와, 각 냉각실을 개폐하는 냉동실도어와 냉장실도어, 및 냉동실과 냉장실에 냉기를 공급하기 위한 압축기, 응축기 및 증발기로 이루어진 냉동시스템을 구비하고 있다. 증발기에서 생성된 냉기는, 각 냉각실의 후방벽내에 형성된 공급덕트를 따라 유동하며, 송풍팬에 의하여 냉각실을 향한 냉기토출구를 통해 각 냉각실로 공급된다.A refrigerator generally includes a cabinet forming a pair of cooling chambers defined by an intermediate partition, that is, a freezer compartment and a refrigerator compartment, a freezer door and a refrigerator compartment door that open and close each cooling compartment, and a compressor and a condenser for supplying cold air to the freezer compartment and the refrigerator compartment. And a refrigeration system consisting of an evaporator. The cold air generated in the evaporator flows along a supply duct formed in the rear wall of each cooling chamber, and is supplied to each cooling chamber by a blower fan through a cold air discharge port toward the cooling chamber.
그런데, 이러한 종래의 냉장고에서는, 냉기토출구를 통해 토출되는 냉기가 집중적으로 제공되는 영역과 비교적 적게 공급되는 영역이 존재하게 되며, 이에 따라 냉각실내의 온도편차가 발생되어 균일한 냉각이 이루어지지 못한다는 문제점이 있다. 그래서, 이러한 문제점을 개선한 소위 입체냉각방식의 냉장고가 제안되어 있다. 입체냉각방식 냉장고는, 냉각실의 후방 벽면 및 양측 벽면에도 각기 다수의 냉기토출구를 마련하여, 냉기의 균일공급을 도모하고 있다.By the way, in the conventional refrigerator, there is a region where the cold air discharged through the cold air discharge port is provided intensively and a region where a relatively small supply is provided, and thus a temperature deviation in the cooling chamber is generated, thereby preventing uniform cooling. There is a problem. Thus, a so-called three-dimensional cooling method refrigerator has been proposed that improves these problems. In the three-dimensional cooling type refrigerator, a plurality of cold air discharge ports are provided on the rear wall and both side walls of the cooling chamber, respectively, to achieve uniform supply of cold air.
그런데, 이러한 입체냉각방식 냉장고에서도, 냉기토출구를 통해 일정방향으로 냉기토출이 이루어지게 되므로, 냉기공급이 불충분한 모서리영역의 사구간이 존재할 수 있다. 특히, 냉각실의 후방벽 뿐만아니라 측벽에도 공급덕트가 마련되어야 하기 때문에, 음식물수용공간을 축소시키고, 부품수 및 공정의 증가로 인해 제조비용이 증대된다는 문제가 있다. However, in such a three-dimensional cooling type refrigerator, since the cold air is discharged in a predetermined direction through the cold air discharge port, there may be a four-segment section of the corner region where the cold air supply is insufficient. In particular, since the supply duct must be provided on the side wall as well as the rear wall of the cooling chamber, there is a problem that the food accommodation space is reduced, and the manufacturing cost increases due to the increase in the number of parts and processes.
냉각실내의 냉기의 균일분배는 냉장고의 대형화 추세와 관련하여 매우 중요한 문제점으로 대두되고 있다.The uniform distribution of cold air in the cooling chamber has emerged as a very important problem in relation to the trend of larger refrigerators.
이에, 본 발명의 출원인은 PCT출원 WO 95/27278에서 냉기분배장치를 갖는 냉장고를 제안한 바 있다. 도 1 내지 도 3은 이 냉기분배장치를 갖는 냉장고의 측단면도, 부분확대단면도 및 주요요소들의 분해사시도이다.Accordingly, the applicant of the present invention has proposed a refrigerator having a cold air distribution device in PCT application WO 95/27278. 1 to 3 are side cross-sectional views, partially enlarged cross-sectional views, and exploded perspective views of main elements of a refrigerator having this cold air distribution device.
이 종래의 냉기분배장치를 갖는 냉장고는, 거의 직육면체형상의 캐비넷(1)내에 중간격벽(5)에 의해 구획된 한 쌍의 냉각실(2, 3)이 마련되어 있다. 이들 냉각실(2, 3)은 각각 비교적 저온의 냉동실(2)과 비교적 고온의 냉장실(3)로 불린다. 각 냉각실(2, 3)의 전면개구에는, 개폐용 도어(6, 7)가 각각 설치되어 있다. 캐비넷(1)내에는 압축기(11)와 도시않은 응축기 및 냉동실증발기(12a)와 냉장실증발기(12b)로 이루어진 냉동시스템이 설치되어 있다. 각 증발기(12a, 12b)에서 생성된 냉기는 냉동실팬(13a) 및 냉장실팬(13b)에 의해 해당 냉각실(2, 3)로 공급된다. In the conventional refrigerator having a cold air distribution device, a pair of cooling chambers 2 and 3 partitioned by an intermediate partition 5 are provided in a substantially rectangular parallelepiped cabinet 1. These cooling chambers 2 and 3 are called the relatively low temperature freezing chamber 2 and the comparatively high temperature refrigerator chamber 3, respectively. Opening and closing doors 6 and 7 are provided at the front openings of the respective cooling chambers 2 and 3, respectively. In the cabinet 1, a refrigeration system comprising a compressor 11, a condenser, a freezer compartment evaporator 12a and a refrigerator compartment evaporator 12b (not shown) is provided. The cold air generated in each of the evaporators 12a and 12b is supplied to the cooling chambers 2 and 3 by the freezing chamber fan 13a and the refrigerating chamber fan 13b.
냉장실(3)의 후방내벽면을 형성하는 내벽판(23)에는 냉장실(3)을 향해 개구된 냉기토출구(16)를 갖는 부분원통상의 덕트플레이트(9)가 부착되어 있고, 이 덕트플레이트(9)와 캐비넷(1)의 후벽(4) 사이에는, 시일판(25)에 의해 격리된 공급덕트(15)와 복귀덕트(17)가 마련되어 있다. 공급덕트(15)내에는 냉장실팬(13b)로부터의 냉기를 하향안내하는 덕트부재(21)가 설치되어 있다. 냉장실증발기(12b)에서 발생한 냉기는 냉장실팬(13b)에 의해 이송되어 공급덕트(15) 및 냉기토출구(16)를 거쳐 냉장실(3)로 공급된다.The inner wall plate 23 forming the rear inner wall surface of the refrigerating compartment 3 is attached with a partial cylindrical duct plate 9 having a cold air discharge port 16 opened toward the refrigerating compartment 3. Between the 9) and the rear wall 4 of the cabinet 1, a supply duct 15 and a return duct 17 separated by the seal plate 25 are provided. In the supply duct 15, a duct member 21 for guiding the cold air from the refrigerating chamber fan 13b is provided. The cold air generated in the refrigerator compartment evaporator 12b is transferred by the refrigerator compartment fan 13b and is supplied to the refrigerator compartment 3 via the supply duct 15 and the cold air outlet 16.
공급덕트(15) 내에는 냉기분배장치(130)가 설치되어 있다. 냉기분배장치(130)는, 수직축선을 갖는 회전축(131)과 각 냉기토출구(16)에 대응하여 회전축(131)에 결합된 냉기분배날개(132) 및 회전축(131)을 회전구동시키는 구동모터(135)를 갖는다. 각 냉기분배날개(132)는 축선방향을 따라 평행하게 배치된 세 개의 원판(136, 137, 138)과, 이들 원판(136, 137, 138) 사이에 위치되는 제 1날개부(133)과 제 2날개부(134)로 이루어져 있다. 각 날개부(133, 134)는 완만한 S자형상의 단면을 갖도록 만곡되어 있고, 각 날개부(133, 134)는 상호 반대방향으로 굴곡되어 있다.The cold air distribution device 130 is installed in the supply duct 15. The cold air distribution device 130 includes a drive motor for rotating the cold air distribution blades 132 and the rotary shaft 131 coupled to the rotary shaft 131 corresponding to the rotary shaft 131 having a vertical axis and the respective cold air discharge ports 16. Has 135. Each cold air distribution wing 132 has three discs 136, 137, and 138 arranged in parallel along the axial direction, and the first wing 133 and the first blade portion 133 positioned between the discs 136, 137, and 138. It consists of two wings 134. Each of the wings 133 and 134 is curved to have a gentle S-shaped cross section, and each of the wings 133 and 134 is bent in opposite directions to each other.
이러한 구성에 의하여, 구동모터(131)가 회전축(131)을 저속으로 회전시키면, 공급덕트(15)를 따라 이동되는 냉기는 냉기분배날개(132)들의 굴곡된 판면에 의해 유로방향이 변환되어, 냉장실(3)내에 좌우로 퍼져서 토출되어 좌우로 분산된다. 한편, 특정 부위에 집중 냉각이 필요할 때에는 그 부위를 향해 냉기가 집중 토출되도록 냉기분배날개(132)의 방향에 맞추어 회전축(131)을 정지시키면 된다. By this configuration, when the drive motor 131 rotates the rotary shaft 131 at a low speed, the cold air moved along the supply duct 15 is converted to the flow path direction by the curved plate surface of the cold air distribution blades 132, It spreads to the left and right in the refrigerating chamber 3, and it is discharged and distributed to left and right. On the other hand, when intensive cooling is required for a specific site, the rotating shaft 131 may be stopped in accordance with the direction of the cold air distribution wing 132 so that cold air is concentrated and discharged toward the site.
그런데, 이러한 냉기분배장치(130)의 각 날개부(133, 134)는 완만한 S형상으로 만곡되어 있기 때문에, 냉기토출구(16)의 주위에서 와류를 형성하여 원만한 냉기흐름을 저해할 수 있다.However, since each wing portion 133, 134 of the cold air distribution device 130 is curved in a gentle S-shape, it is possible to form a vortex around the cold air discharge port 16 to inhibit a smooth cold air flow.
또한, 이 종래의 냉기분배장치(130)는, 수평방향에서의 냉기의 균일배분은 어느 정도 달성할 수 있으나, 수직방향에서는 냉기의 토출 방향의 조절이 되지 않으므로 수직방향에서의 냉기의 균일배분이 충분히 이루어지지 않는다는 단점이 있다. 따라서, 냉장실(3) 전체의 균일냉각의 실현에 한계가 가진다.In addition, the conventional cold air distribution device 130 can achieve uniform distribution of cold air in the horizontal direction to some extent, but since the discharge direction of cold air is not adjusted in the vertical direction, uniform distribution of cold air in the vertical direction is achieved. The disadvantage is that it is not made sufficiently. Therefore, there is a limit to the realization of uniform cooling of the entire refrigerating chamber 3.
따라서, 본 발명의 목적은, 종래의 이러한 문제점들을 고려하여, 와류를 발생시키지 않으며, 수평 및 수직방향에서의 냉기의 균일한 배분을 효과적으로 달성할 수 있는 냉기분배장치을 갖는 냉장고를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a refrigerator having a cold air distribution device which can effectively achieve uniform distribution of cold air in the horizontal and vertical directions without generating vortices in view of these conventional problems.

바람직하게는, 상기 고정공 중 하나는 다른 하나를 중심으로한 원호상의 장공으로 형성된다. 또한, 상기 장공의 일 부위에는 상기 장공에 삽입된 상기 장착핀이 걸리는 적어도 하나의 걸림홈이 형성된다. 이에 의해 상기 보조날개의 경사각의 조절이 가능하게 된다.Preferably, one of the fixing holes is formed as an arc-shaped long hole centered on the other. In addition, at one portion of the long hole is formed at least one locking groove that is caught by the mounting pin inserted in the long hole. Thereby, the inclination angle of the auxiliary blade can be adjusted.
상기 회전축은 상기 냉기분배날개의 중앙부위에 결합되며, 이에 의해 상기 냉기분배날개는 상기 회전축의 측방에 배치된 두 개의 날개부를 갖게 된다.The rotating shaft is coupled to the central portion of the cold air distribution blade, whereby the cold air distribution blade has two wings arranged on the side of the rotation shaft.

상기와 같은 구성을 갖는 본 발명에 따른 냉장고의 작동은 다음과 같다.Operation of the refrigerator according to the present invention having the configuration as described above is as follows.
도 10 내지 도 12는 본 발명의 제 1실시예에 따른 냉기분배장치(30)의 냉기분배과정을 순차적으로 도시하고 있다. 구동모터(35)에 의해 회전축(31)이 회전하는 동안 냉기분배날개(41a, 41b, 41c)가 도 10에 도시된 바와 같이 위치되면, 공급덕트(15)내의 냉기는 정면으로 토출된다. 그리고, 냉기분배날개(41a, 41b, 41c)가 도 11 및 도 12에 각각 도시된 바와 같이 좌향 또는 우향 회전된 상태에서는, 공급덕트(15) 내의 냉기는 좌향 또는 우향 토출된다.10 to 12 sequentially illustrate a cold air distribution process of the cold air distribution device 30 according to the first embodiment of the present invention. When the cold air distribution blades 41a, 41b, 41c are positioned as shown in FIG. 10 while the rotary shaft 31 is rotated by the drive motor 35, the cold air in the supply duct 15 is discharged to the front. Then, in the state in which the cold air distribution blades 41a, 41b, 41c are rotated leftward or rightward as shown in Figs. 11 and 12, respectively, the cold air in the supply duct 15 is discharged leftward or rightward.
이와 같이, 냉기분배날개(41a, 41b, 41c)의 회전각위치의 변화에 따라 냉기의 토출 방향이 수평방향에서 연속적으로 변화하기 때문에, 냉기는 냉장실(3)내에 균일하게 분산되어 공급되게 된다. 또한, 냉기분배날개(41a, 41b, 41c)는 평판상으로 형성되어 있으므로, 냉기분배날개(41a, 41b, 41c)의 회전에 따른 와류형상이 발생하지 않는다.In this way, since the discharge direction of the cold air continuously changes in the horizontal direction in accordance with the change in the rotation angle positions of the cold air distribution blades 41a, 41b, 41c, the cold air is uniformly distributed in the refrigerating chamber 3 and supplied. In addition, since the cold air distribution blades 41a, 41b, and 41c are formed in a flat plate shape, no vortex shape occurs due to the rotation of the cold air distribution blades 41a, 41b, and 41c.
그리고, 좌측 혹은 우측의 특정영역에 냉기의 집중공급이 필요한 경우에는, 냉기분배날개(41a, 41b, 41c)가 해당영역을 향하도록 한 상태에서 구동모터(35)를 정지시켜 둠으로써 집중냉각을 실현할 수 있다. 이 경우에는, 도시되지 않은 제어부는 온도센서(9a, 9b)를 통해 감지한 냉장실(3) 내의 온도에 기초하여 구동모터(35)를 구동한다. 즉, 냉장실(3) 내의 특정 부위의 온도 상승이 온도센서(9a, 9b)를 통해 감지되면, 제어부는 냉기분배날개(41a, 41b, 41c)에 의해 그 특정 부위를 향해 냉기가 안내되도록 회전축(31)을 정지시킨다. 따라서, 온도가 상승된 특정 부위가 집중 냉각되고, 냉장실(3)의 온도가 단시간 내에 균일하게 유지되게 된다.When concentrated supply of cold air is required in a specific region on the left or right side, concentrated cooling is performed by stopping the driving motor 35 with the cold distribution blades 41a, 41b, and 41c facing the corresponding region. It can be realized. In this case, the control unit (not shown) drives the driving motor 35 based on the temperature in the refrigerating chamber 3 sensed by the temperature sensors 9a and 9b. That is, when a temperature rise of a specific part in the refrigerating compartment 3 is sensed through the temperature sensors 9a and 9b, the control unit may rotate the rotation shaft such that the cold air is guided toward the specific part by the cold air distribution blades 41a, 41b and 41c. 31) Stop. Therefore, the specific site where the temperature is raised is concentrated and the temperature of the refrigerating chamber 3 is kept uniform within a short time.
또한, 사용자는 보조날개(51)의 각위치를 수동으로 조절함으로써, 냉기의 상하방향상의 토출 방향을 조절할 수 있다. 보조날개(51)가 소정 각도로 경사진 상태에서는, 회전축(31)이 구동모터(35)에 의해 지속적으로 회전할 때는 냉기의 수직방향상의 분산이 이루어지게 되며, 회전축(31)이 정지된 상태에서는 수직방향상의 특정 부위에 대한 집중 냉각이 수행되게 된다.In addition, the user can adjust the discharge direction in the vertical direction of the cold air by manually adjusting the angular position of the auxiliary blade (51). In the state in which the auxiliary blade 51 is inclined at a predetermined angle, when the rotary shaft 31 is continuously rotated by the drive motor 35, the vertical dispersion of cold air is made, and the rotary shaft 31 is stopped. In this case, concentrated cooling is performed on a specific part in the vertical direction.
