The louver 26 is provided with a plurality of supply holes 28 for supplying the cold air heat-exchanged with the evaporator 20 into the freezing chamber 12 by the blowing fan 22 for the freezing chamber 12.
냉기덕트 시스템은 사절판(18)에 각각 형성되며, 냉동실(12)의 하단부와 증발기(20)의 하단부가 서로 연통되도록 형성된 냉동실 냉기 리턴 덕트(30), 냉장실(14)의 상단부와 증발기(20)의 하단부가 서로 연통되도록 형성된 냉장실 냉기 리턴 덕트(32) 및 냉동실(12)의 후벽부(11) 내에 마련된 냉장실 냉기 공급덕트(34)를 포함한다. 냉장실 냉기 공급덕트(34)는, 도 2에 도시한 바와 같이, 증발기(20)와 열교환한 냉기가 냉장실(14) 배면(16)의 좌, 우측과 연통되도록 냉장고(10)의 후벽부(11)에 분기되어 내장, 설치된다. 냉장실(14)의 배면(16) 좌, 우측으로 공급된 냉기의 일부는 배면(16)에 형성된 다수의 토출구(17)를 통해 냉장실(14)로 공급되며, 다른 일부는 냉장고(10)의 양 측면(도시하지 않음)에 형성된 다수의 토출구를 통해, 냉장실(14)로 각각 공급된다.The cold air duct system is formed in the trimming plate 18, and the freezer compartment cold return duct 30 and the top end of the refrigerating compartment 14 and the evaporator 20 are formed so that the lower end of the freezer compartment 12 and the lower end of the evaporator 20 communicate with each other. The refrigerator compartment cold air return duct 32 and the refrigerator compartment cold air supply duct 34 provided in the rear wall part 11 of the freezing compartment 12 are formed so that the lower end portions of the c) communicate with each other. As illustrated in FIG. 2, the refrigerating chamber cold air supply duct 34 has a rear wall portion 11 of the refrigerator 10 such that the cold air that has exchanged heat with the evaporator 20 communicates with the left and right sides of the rear surface 16 of the refrigerating chamber 14. It is branched and installed inside. A part of the cold air supplied to the left and right sides of the rear surface 16 of the refrigerating chamber 14 is supplied to the refrigerating chamber 14 through a plurality of discharge ports 17 formed on the rear surface 16, and the other part of the refrigerator 10 Through a plurality of discharge ports formed on the side surfaces (not shown), they are respectively supplied to the refrigerating chamber 14.
이러한 냉장고(10)에 있어서, 사용자가 냉장고(10)를 이용하기 위해 냉동실 도어(13) 또는 냉장실 도어(15)를 개폐하게 되면, 냉동실(12) 및 냉장실(14)의 실내온도가 상승하게 된다. 이러한 실내온도의 상승이 온도감지장치(도시하지 않음)에 의해 감지되면, 온도감지장치로부터의 신호에 응답해서 냉매를 순환시키는 것에 의해 냉동실(12) 및 냉장실(14)의 실내를 적정 온도로 유지하게 된다.In the refrigerator 10, when the user opens or closes the freezer compartment door 13 or the refrigerating compartment door 15 to use the refrigerator 10, the room temperature of the freezer compartment 12 and the refrigerating compartment 14 is increased. . When such an increase in the indoor temperature is detected by a temperature sensor (not shown), the interior of the freezer compartment 12 and the refrigerating chamber 14 is maintained at an appropriate temperature by circulating a refrigerant in response to a signal from the temperature sensor. Done.
냉동실(12)의 상대적으로 온도가 높은 냉기는 냉동실(12)용 송풍팬(13)의 회전에 의해 사절판(18)의 냉동실 냉기 리턴 덕트(30)를 따라 증발기(20)에 도달한 후 열교환되어 루버(26)의 냉동실 냉기 공급공(28)을 통해 냉동실(12)로 공급되며, 냉장실(14)의 상대적으로 온도가 높은 냉기는 냉장실(14)용 송풍팬(24)의 구동에 의해 사절판(18)의 냉장실 냉기 리턴 덕트(32)를 따라 증발기(20)에 도달한 후 열교환되어, 냉장실(14)의 배면(16) 및 양 측면의 토출구를 통해 냉장실(14)로 공급된다.The relatively high temperature cold air of the freezer compartment 12 reaches the evaporator 20 along the freezer compartment cold air return duct 30 of the trimming plate 18 by the rotation of the blower fan 13 for the freezer compartment 12. And supplied to the freezing compartment 12 through the freezer compartment cold air supply hole 28 of the louver 26, and the relatively high temperature of the refrigerating compartment 14 is driven by driving the blower fan 24 for the refrigerating compartment 14. After reaching the evaporator 20 along the refrigerating chamber cold air return duct 32 of the printing plate 18, it is heat-exchanged, and is supplied to the refrigerating chamber 14 through the rear surface 16 of the refrigerating chamber 14 and the discharge ports on both sides.
그러나, 이러한 구성의 냉장고에 있어서, 냉동실용 송풍팬 및 냉장실용 송풍팬이 냉동실의 후방에 함께 설치되어 있으므로, 냉동실용 송풍팬의 위치에 제한되어 루버의 냉동실 냉기 공급공의 위치도 제한되어, 이로 인해 냉동실 내의 온도 분포가 불균일하게 되었다. 또한, 냉장실용 송풍팬이 중앙부로부터 일정간격 편향되게 설치되어, 냉장실 냉기 공급덕트가 분기될 때 덕트 구성이 복잡할 뿐만 아니라, 냉장실로의 냉기 흐름이 원활하지 못하였다. 따라서, 냉장실 내의 온도 분포가 불균일하게 되며, 또한 이를 해소하기 위해 상술한 송풍팬의 능력을 증가시킬 경우 전력 소비 및 소음이 증대된다는 문제점이 있었다.However, in the refrigerator having such a configuration, since the freezing compartment blowing fan and the refrigerating compartment blowing fan are provided together at the rear of the freezing compartment, the freezing compartment blowing fan is limited to the position of the freezing compartment blowing fan, and thus the position of the freezer cold air supply hole of the louver is also limited. This results in uneven temperature distribution in the freezer. In addition, the cooling fan for the cooling room is installed so as to be deflected at a predetermined interval from the center, when the refrigerating chamber cold air supply duct is not only complicated duct configuration, the cold air flow to the refrigerating chamber was not smooth. Therefore, there is a problem that the temperature distribution in the refrigerating chamber becomes non-uniform, and the power consumption and the noise are increased when the capacity of the above-described blower fan is increased to solve the problem.
본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로, 냉동실 후방에 설치된 냉동실용 송풍팬 및 냉장실 후방에 설치된 냉장실용 송풍팬을 구비하여, 냉동실 및 냉장실의 온도분포를 균일하게 유지할 수 있는 냉기 순환 시스템을 제공하고 냉기 순환 덕트를 단순화하여 유로 저항을 감소시켜 효율적인 냉장고 냉기 순환 시스템을 제공하는데 그 목적이 있다.The present invention is to solve such a conventional problem, provided with a freezing fan blower installed in the rear of the freezer compartment and a freezer blower fan installed in the rear of the refrigerating compartment, a cold air circulation system capable of maintaining the temperature distribution of the freezer compartment and the refrigerating compartment uniformly. The purpose of the present invention is to provide an efficient refrigerator cold air circulation system by reducing the flow path resistance by simplifying the cold air circulation duct.

냉동실(12)의 상대적으로 온도가 높은 냉기는 냉동실(12)용 송풍팬(13)의 회전에 의해 사절판(18)의 냉동실 냉기 리턴 덕트(30)를 따라 증발기(20)에 도달한 후 열교환되어 루버(26)의 냉동실 냉기 공급공(28)을 통해 냉동실(12)로 공급되며, 냉장실(14)의 상대적으로 온도가 높은 냉기는 냉동실(12)용 송풍팬(13)의 구동에 의해 사절판(18)의 냉장실 냉기 리턴 덕트(32)를 따라 증발기(20)에 도달하여 열교환된 후, 시로코 팬(50)의 구동에 의해 냉장실 냉기 공급통로(60)를 통해 그의 분기점까지 도달한다. 그후, 그의 일부는 냉장실 상면 냉기 공급덕트(70)를 통해 상면(19)으로, 다른 일부는 배면(16) 및 양 측면의 토출구를 통해 냉장실(14)로 각각 공급된다.The relatively high temperature cold air of the freezer compartment 12 reaches the evaporator 20 along the freezer compartment cold air return duct 30 of the trimming plate 18 by the rotation of the blower fan 13 for the freezer compartment 12. And supplied to the freezing compartment 12 through the freezer compartment cold air supply hole 28 of the louver 26, and the relatively high temperature of the refrigerating compartment 14 is driven by driving the blower fan 13 for the freezing compartment 12. After reaching and heat-exchanging the evaporator 20 along the refrigerator compartment cold air return duct 32 of the printing plate 18, it reaches to the branch point through the refrigerator compartment cold air supply passage 60 by the drive of the sirocco fan 50. As shown in FIG. Thereafter, a part thereof is supplied to the refrigerating chamber 14 through the refrigerating chamber upper surface air supply duct 70 to the upper surface 19 and the other part to the refrigerating chamber 14 through the rear surface 16 and the discharge ports on both sides.
상술한 바와 같이 본 발명은 바람직한 예를 중심으로 설명 및 도시되었으나, 본 기술분야의 숙련자라면 본 발명의 사상 및 범주를 벗어나지 않고 다양하게 변형 실시할 수 있음을 알 수 있을 것이다.As described above, the present invention has been described and illustrated with reference to preferred examples, but it will be apparent to those skilled in the art that various modifications may be made without departing from the spirit and scope of the present invention.
상술한 바와 같이 본 발명에 따르면, 냉동실용 송풍팬 및 냉장실용 송풍팬이냉동실 후방 및 냉장실의 후방에 각각 설치되어 있으므로, 냉동실용 송풍팬의 위치에 제한됨이 없이 루버의 냉동실 냉기 공급공의 위치를 설정할 수 있어, 냉동실 내의 온도 분포가 균일하게 된다. 또한, 냉장실 냉기 공급덕트가 직선적으로 간단하게 구성되며, 냉장실의 4면을 통해 냉장실로 냉기를 공급하므로, 냉장실 내의 온도 분포도 균일하게 된다.As described above, according to the present invention, since the freezing compartment blowing fan and the refrigerating compartment blowing fan are installed at the rear of the freezing compartment and the rear of the refrigerating compartment, the position of the freezer cold air supply hole of the louver is not limited to the position of the freezing compartment blowing fan. It can set, and the temperature distribution in a freezer compartment will be uniform. In addition, since the refrigerating chamber cold air supply duct is simply and linearly supplied, and cold air is supplied to the refrigerating chamber through the four sides of the refrigerating chamber, the temperature distribution in the refrigerating chamber is also uniform.
