이하에서는 본 고안의 바람직한 하나의 실시예를 도면을 참조하여 상세히 설명한다. Hereinafter, one preferred embodiment of the present invention will be described in detail with reference to the drawings.

본 고안에 따른 냉장고는 도 1에 도시한 바와 같이 외관을 이루며 전면이 전방측으로 개방되어 내부에 저장물을 저온으로 저장하는 저장실(10a)이 형성되어 있 는 본체(10)와, 본체(10)의 일측에 힌지결합되어 저장실(10a)을 개폐하는 도어(20)를 포함한다. The refrigerator according to the present invention has a main body 10 and a main body 10 having an appearance as shown in FIG. 1 and having a storage chamber 10a having a front surface open to the front side and storing the storage at a low temperature therein. The door 20 is hinged to one side of the opening and closing the storage compartment (10a).

본체(10)의 후방측 하부에는 냉매를 압축하는 압축기(11)가 설치되는 기계실(10b)이 마련되며, 저장실(10a)의 후방측에는 냉기를 발생시키는 증발기(12)와 흡입력 및 송풍력을 발생시켜 증발기(12)에서 발생한 냉기가 저장실(10a)을 순환하도록 하는 송풍팬(13)이 설치되는 냉각실(10c)과 증발기(12)에서 발생한 냉기가 저장실(10a)의 상하로 분산되어 공급될 수 있도록 하는 냉기유로(10d)가 상하로 길게 연장 형성되어 있다. A mechanical chamber 10b is provided at the lower rear side of the main body 10, in which a compressor 11 for compressing the refrigerant is installed, and at the rear side of the storage chamber 10a, an evaporator 12 which generates cold air and a suction force and a blowing force are generated. The cooling chamber 10c in which the blower fan 13 is installed so that the cold air generated in the evaporator 12 circulates the storage chamber 10a and the cold air generated in the evaporator 12 are distributed and supplied to the upper and lower sides of the storage chamber 10a. The cold air flow passage 10d is formed to extend up and down long.

저장실(10a) 내에는 다수의 저장물을 효율적으로 구획하여 저장할 수 있도록 하기 위하여 다수의 선반(14)이 배치되며, 도어(20)의 내측에는 캔이나 음료용기 등을 보관하기 위한 다수의 도어선반(21)이 배치된다. A plurality of shelves 14 are arranged in the storage compartment 10a to efficiently partition and store a plurality of storages, and a plurality of door shelves for storing cans or beverage containers inside the door 20. 21 is arranged.

또한, 본 고안에 따른 냉장고에는 저장실(10a)과는 별도로 내부의 온도가 독립적으로 조절되는 보조 저장실(10e)이 마련되어 있다. 보조 저장실(10e)은 평판 형상으로 형성되어 저장실(10a)의 하부 일부 구역이 저장실(10a)과 구획되도록 하여 보조 저장실(10e)이 형성되도록 하는 구획선반(17)에 의해 형성되며, 이러한 보조 저장실(10e)에는 저장물을 담을 수 있도록 상면이 개방된 함체 형상으로 형성된 보조 저장서랍(16)이 전후방향으로 진퇴이동가능하게 설치되어 있다. In addition, the refrigerator according to the present invention is provided with an auxiliary storage compartment 10e in which an internal temperature is independently controlled, apart from the storage compartment 10a. The auxiliary storage compartment 10e is formed by a partition shelf 17 that is formed in a flat plate shape so that a lower portion of the storage compartment 10a is partitioned from the storage compartment 10a so that the auxiliary storage compartment 10e is formed. At 10e, an auxiliary storage drawer 16 formed in a shape of an enclosure having an upper surface open to accommodate a storage is provided to move forwards and backwards.

상술한 바와 같이 보조 저장실(10e)의 내부온도가 저장실(10a)과 별도로 독립적으로 조절될 수 있도록 하기 위해 구획선반(17)에는 도 2에 도시한 바와 같이 보조 저장실(10e)로 유입되는 냉기의 양을 조절하는 댐퍼(30)와, 댐퍼(30)가 개폐 되도록 하는 댐퍼조절장치(40)가 설치되어 있다. As described above, in order to allow the internal temperature of the auxiliary storage compartment 10e to be independently controlled from the storage compartment 10a, the partition shelf 17 may be configured to provide A damper 30 for adjusting the amount and a damper control device 40 for opening and closing the damper 30 is provided.

댐퍼조절장치(40)는 후단에 제 1 랙기어(41a)가 형성되며 사용자에 의해 가해진 외력에 의해 좌우방향으로 진퇴이동하는 제 1 랙기어부재(41)와, 제 1 랙기어(41a)에 이물림되어 제 1 랙기어부재(41)가 좌우방향으로 진퇴이동함에 따라 정역 회전하는 피니언(42)과, 피니언(42)과 이물림되는 제 2 랙기어(43a)가 형성되며 후단에 댐퍼(30)가 연결되어 피니언(42)이 정역회전함에 따라 전후방향으로 진퇴이동하며 댐퍼(30)가 진퇴이동 하도록 하는 제 2 랙기어부재(43)를 포함한다.The damper adjusting device 40 has a first rack gear 41a formed at a rear end thereof, and is provided to the first rack gear member 41 and the first rack gear 41a which move forward and backward in the left and right directions by an external force applied by the user. As the first rack gear member 41 is moved and moved forward and backward in the left and right directions, a pinion 42 for forward and reverse rotation is formed, and a second rack gear 43a that is engaged with the pinion 42 is formed, and a damper at the rear end thereof. 30 is connected to the pinion 42 includes a second rack gear member 43 to move forward and backward in the forward and backward direction as the forward and reverse rotation and the damper 30 to move forward and backward.

댐퍼조절장치(40)의 설치를 위해 구획선반(17)은 냉기유로(10d)와 연결되어 냉기가 전달되는 유입구(17a)와 보조 저장실(10e) 내부로 냉기가 토출되는 유출구(17b)가 형성되어 있는 하판(17L)과, 하판(17L)의 상면을 덮으며 후방측에 냉기를 유입구(17a)로부터 유출구(17b)로 안내하는 냉기안내부(17c)가 형성된 상판(17U)을 포함하여, 상판(17U)의 냉기안내부(17c) 내측에 댐퍼(30)가 설치되며 상판(17U)과 하판(17L) 사이에 댐퍼조절장치(40)가 설치된다. In order to install the damper control device 40, the partition shelf 17 is connected to the cold air passage 10d to form an inlet 17a through which cold air is delivered and an outlet 17b through which cold air is discharged into the auxiliary storage chamber 10e. Including a lower plate 17L and an upper plate 17U having a cold air guide portion 17c covering the upper surface of the lower plate 17L and guiding cold air from the inlet port 17a to the outlet port 17b on the rear side, The damper 30 is installed inside the cold air guide 17c of the upper plate 17U, and the damper adjusting device 40 is installed between the upper plate 17U and the lower plate 17L.

이때, 제 1 랙기어부재(41)의 전단에는 상측으로 손잡이부(41b)가 돌출되어 사용자가 손잡이부(41b)를 통해 용이하게 외력을 가해 제 1 랙기어부재(41)를 좌우방향으로 이동시킬 수 있도록 되어 있으며, 상판(17U)의 전단측에는 좌우방향으로 길게 연장 형성되어 손잡이부(41b)가 관통하여 돌출되도록 설치되는 가이드홀(17d)이 마련되어 있다. At this time, the front end of the first rack gear member 41, the handle portion 41b protrudes upwards so that the user easily applies an external force through the handle portion 41b to move the first rack gear member 41 in left and right directions. A guide hole 17d is formed on the front end side of the upper plate 17U so as to extend in the left and right direction so that the handle portion 41b can protrude through.

따라서, 사용자가 도 3에 도시한 바와 같이 가이드홀(17d)에 돌출되어 있는 손잡이부(41b)를 통해 제 1 랙기어부재(41)에 외력을 가하여 제 1 랙기어부재(41) 가 좌측 또는 우측으로 이동하게 하면, 제 1 랙기어(41a)에 이물림되어 있는 피니언(42)이 회전하면서 제 2 랙기어(43a)에 힘을 전달하고 이에 의해 제 2 랙기어부재(43)와 제 2 랙기어부재(43)의 후단에 설치되어 있는 댐퍼(30)는 제 2 랙기어(43a)를 통해 전달된 힘에 의해 전방측이나 후방측으로 이동한다. 따라서, 하판(17L)에 형성되어 있는 유출구(17b)는 전후방향으로 진퇴이동하는 댐퍼(30)에 의해 그 일부 혹은 전부가 개방되므로, 유출구(17b)의 개방여부 및 개방정도에 따라 유출구(17b)를 통해 토출되는 냉기의 토출량이 변경되어 보조 저장실(10e)의 온도는 조절된다. Accordingly, the user applies external force to the first rack gear member 41 through the handle portion 41b protruding from the guide hole 17d as shown in FIG. 3 so that the first rack gear member 41 is left or right. When moving to the right, the pinion 42, which is engaged by the first rack gear 41a, rotates to transmit the force to the second rack gear 43a, thereby transmitting the second rack gear member 43 and the second. The damper 30 installed at the rear end of the rack gear member 43 moves to the front side or the rear side by the force transmitted through the second rack gear 43a. Therefore, since the outlet 17b formed in the lower plate 17L is partially or entirely opened by the damper 30 moving forward and backward, the outlet 17b is opened depending on whether the outlet 17b is opened and the degree of opening. The discharge amount of the cold air discharged through) is changed so that the temperature of the auxiliary storage chamber 10e is adjusted.
