At this time, the water supply pipe 15 for transmitting water from the external water supply source is disposed above the ice making device (30).

얼음공급장치(40)는 상측으로 개방되어 상부의 제빙장치(30)에서 낙하한 얼음을 받아 저장하는 얼음저장통(41)과 얼음저장통(41) 내에 설치되어 회전하며 얼음을 배출안내관(21)측으로 이동시키는 얼음이송장치(42)를 포함한다.

In addition, the refrigerator according to the present invention is able to adjust the time for producing ice as needed. In other words, it is possible to perform two modes, a transparent ice manufacturing mode in which water is cooled slowly for a relatively long time to obtain transparent ice, and a rapid ice manufacturing mode in which water is rapidly cooled in a relatively short time. It is.

이를 위해 안내덕트(14)에는 도 2에 도시한 바와 같이 제빙트레이(31)의 상부측과 대응하는 위치에 마련되어 제빙트레이(31)의 상부측으로 냉기가 토출될 수 있게 하는 상부 토출구(16a)와, 제빙트레이(31)의 하부측과 대응하는 위치에 마련 되어 제빙트레이(31)의 하부측으로 냉기가 토출될 수 있게 하는 하부 토출구(17a)가 마련되어 있으며, 안내덕트(14) 내에는 상부 토출구(16a)로의 냉기 공급을 선택적으로 제한하는 댐핑장치(50)가 구비되어 있다. 본 실시예에서 상부 토출구(16a) 및 하부 토출구(17a)는 안내덕트(14)로부터 전방측으로 일체로 연장형성되며 점진적으로 줄어드는 단면을 갖도록 형성되어 통과하는 냉기의 유속을 증가시키는 상부 노즐(16) 및 하부 노즐(17)의 선단에 각각 마련되어 있다. To this end, the guide duct 14 has an upper discharge port 16a provided at a position corresponding to the upper side of the ice making tray 31 to discharge cold air to the upper side of the ice making tray 31, as shown in FIG. The lower discharge port 17a is provided at a position corresponding to the lower side of the ice making tray 31 to discharge cold air to the lower side of the ice making tray 31. A damping device 50 is provided for selectively limiting the supply of cold air to 16a. In the present embodiment, the upper discharge port 16a and the lower discharge port 17a are formed integrally extending forwardly from the guide duct 14 and have a gradually decreasing cross section to increase the flow velocity of cold air passing therethrough. And the tip of the lower nozzle 17, respectively.

따라서, 물을 긴 시간 동안 천천히 냉각하여 투명한 얼음을 얻기 위한 투명얼음 제조모드가 수행될 경우에는 댐핑장치(50)가 상부 토출구(16a)로의 냉기 전달을 제한하여 하부 토출구(17a)를 통해서만 냉기가 제빙트레이(31)의 하부로 전달되므로 제빙트레이(31)에 담긴 물이 하측의 제빙트레이(31)를 통해 냉기를 전달받아 천천히 냉각되어 투명한 얼음이 제조될 수 있으며, 물을 짧은 시간동안 빠르게 냉각하여 빠른 시간 내에 얼음을 얻기 위한 급속얼음 제조모드가 수행될 경우에는 도 3에 도시한 바와 같이 댐핑장치(50)가 상부 토출구(16a)로의 냉기 전달을 가능하게 하여 상부 토출구(16a) 및 하부 토출구(17a)를 통해 냉기가 제빙트레이(31)의 상부 및 하부로 모두 전달되어 제빙트레이(31)에 담긴 물이 하측의 제빙트레이(31)를 통해 냉기를 전달받을 뿐만 아니라 상측에 공급된 냉기와 직접 접하여 냉각되므로 빠른 시간 내에 얼음이 제조될 수 있게 되는 것이다. Therefore, when the transparent ice manufacturing mode for cooling the water slowly and obtaining transparent ice is performed for a long time, the damping device 50 restricts the transfer of cold air to the upper discharge port 16a so that the cold air only passes through the lower discharge port 17a. Since it is delivered to the lower part of the ice making tray 31, the water contained in the ice making tray 31 receives cold air through the lower ice making tray 31, and is cooled slowly to produce transparent ice. When the rapid ice manufacturing mode is performed to obtain ice within a short time, as shown in FIG. 3, the damping device 50 enables cold air to be transferred to the upper discharge port 16a, thereby allowing the upper discharge port 16a and the lower discharge port to be discharged. Cold air is delivered to both the upper and lower portions of the ice making tray 31 through the 17a so that the water contained in the ice making tray 31 receives the cooling air through the lower ice making tray 31. Since direct cooling contact with the cooling air supplied to the upper side so that the ice will be made in a short time.

댐핑장치(50)는 안내덕트(14) 내에 회전 가능하게 설치되어 회전하며 상부 토출구(16a)로의 냉기 전달을 선택적으로 제한하는 댐퍼(51)와, 솔레노이드(52)에 의해 상측으로 이동하며 댐퍼(51)를 회전시키는 로드(53)와, 로드(53)를 탄성지지 하여 솔레노이드(52)에 의한 로드(53)에 전달되던 힘이 해제되었을 때 로드(53)가 원위치로 복원될 수 있게 하는 탄성부재(54)를 포함한다. The damping device 50 is rotatably installed in the guide duct 14 and rotates upwardly by a damper 51 and a solenoid 52 that selectively restricts the transfer of cold air to the upper discharge port 16a. A rod 53 for rotating the rod 51 and an elastic member for elastically supporting the rod 53 so that the rod 53 can be restored to its original position when the force transmitted to the rod 53 by the solenoid 52 is released. Member 54.

따라서, 투명얼음 제조모드에서는 솔레노이드(52)에 의해 로드가 상측으로 전진하며 댐퍼(51)를 회전시켜 댐퍼(51)가 상부 토출구(16a)로의 냉기 전달을 제한하므로 냉기가 하부 토출구(17a)를 통해서만 제빙트레이(31)의 하부에 전달되며, 급속얼음 제조모드에서는 탄성부재(54)의 탄성력에 의해 로드(53)가 하측으로 후진하며 댐퍼(51)를 원위치로 복원시키므로 냉기가 하부 토출구(17a) 뿐만 아니라 상부 토출구(16a)를 통해 제빙트레이(31)의 하부 및 상부에 모두 전달되게 되는 것이다. Therefore, in the transparent ice manufacturing mode, the rod is advanced upward by the solenoid 52 and the damper 51 is rotated so that the damper 51 restricts the transfer of cold air to the upper discharge port 16a. It is transmitted to the lower portion of the ice making tray 31 only, and in the rapid ice manufacturing mode, the rod 53 retreats downward by the elastic force of the elastic member 54, and the damper 51 is restored to its original position. ) As well as to be delivered to both the lower and upper portion of the ice making tray 31 through the upper discharge port (16a).

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉장고는 안내덕트에 제빙트레이의 상부로 냉기를 토출하는 상부 토출구와 제빙트레이의 하부로 냉기를 토출하는 하부 토출구가 마련되어 있으며, 상부 토출구로의 냉기전달이 선택적으로 이루어질 수 있게 하는 댐핑장치가 구비되어 있으므로, 얼음을 빠른 시간 내에 제조하기 위한 급속냉각 모드와, 투명한 얼음을 제조하기 위한 투명얼음제조 모드 중 어느 하나를 선택적으로 수행할 수 있게 되는 작용효과가 있다. As described in detail above, the refrigerator according to the present invention has an upper discharge port for discharging cold air to the upper portion of the ice making tray and a lower discharge hole for discharging cold air to the lower portion of the ice making tray, and the cold air is delivered to the upper discharge hole. Since the damping device is selectively provided, the effect of being able to selectively perform either a quick cooling mode for producing ice quickly or a transparent ice manufacturing mode for producing transparent ice is provided. have.
