The evaporator in the circulation circuit absorbs the heat from the outside to keep the inside frozen and refrigerated.
이러한 종래 냉장고에 있어 냉장실로 냉기를 공급하는 구조 및 냉기 공급과정을 첨부된 도면을 참조하여 설명하면 다음과 같다.Referring to the accompanying drawings, a structure and a cold air supply process for supplying cold air to the refrigerating chamber in the conventional refrigerator are as follows.
도 1은 종래 냉장고의 내부구조를 보인 종단면도이고, 도 2는 도 1에 도시된 냉장실을 단면하여 도시한 단면도로써, 도 1 및 도 2에 도시한 바와 같이 냉장고는 본체(1)의 일정부위에 장착된 분리벽(16)에 의해 냉동실(10)과 냉장실(20)로 나뉘어져 구획되고, 그 냉기 공급구조를 살펴보면, 저온 저압의 냉매가 내부를 통과하는 증발기(3)에서 열 교환되어 냉각된 냉기의 일부는 송풍팬(13)에 의해 강제 송풍되어 쉬라우드(Shroud)(14)를 거쳐 상기 냉동실(10)로 공급되고, 나머지 냉기의 일부는 상기 쉬라우드(14)를 거쳐 자유낙하 하여 냉장실 냉기안내유로(15)를 통하여 상기 냉장실(20)측으로 안내된다.1 is a vertical cross-sectional view showing the internal structure of a conventional refrigerator, Figure 2 is a cross-sectional view showing a cross-sectional view of the refrigerator compartment shown in Figure 1, as shown in Figures 1 and 2 the refrigerator is a certain portion of the body (1). It is divided into a freezer compartment 10 and a refrigerating compartment 20 by a partition wall 16 mounted on the same, and looks at the cold air supply structure, the refrigerant having low temperature and low pressure is heat exchanged and cooled in the evaporator 3 passing through the inside. Part of the cold air is forcibly blown by the blower fan 13 to be supplied to the freezing compartment 10 through the shroud 14, and a part of the remaining cold air is freely dropped through the shroud 14 to freeze the refrigerating compartment. It is guided to the refrigerating compartment 20 side through the cold air flow passage 15.

The cold air falling freely and freely falling through the cold air guide passage 15 is supplied to the refrigerating compartment 20 through a plurality of refrigerating compartment discharge ports 15a formed on the rear side of the refrigerating compartment that is in contact with the refrigerating compartment cold air guide passage 15. 20) It is configured to cool the inside.
이와 같은 과정을 통하여 상기 냉동실(10) 및 냉장실(20)에 공급된 냉기는 내부에 적재된 음식물을 냉각시킨 후, 상기 분리벽(16)의 내부에 형성된 흡입로(16a)를 통해 다시 증발기(3) 부근으로 재 유입되어 재 냉각된다. 냉장실(20)의 내부 온도가 적정온도를 유지하게 되면 냉장실(20) 내부에 장착된 온도센서(미도시)의 감지신호를 전달받은 제어부에 의해 냉각장치의 작동이 일정기간동안 일시적으로 정지하게 된다.The cold air supplied to the freezing compartment 10 and the refrigerating compartment 20 through such a process cools the food loaded therein, and then again evaporates through the suction passage 16a formed in the separation wall 16. 3) It is reintroduced to the vicinity and recooled. When the internal temperature of the refrigerating compartment 20 maintains an appropriate temperature, the operation of the cooling apparatus is temporarily stopped by a controller which receives a detection signal of a temperature sensor (not shown) mounted inside the refrigerating compartment 20 for a predetermined period of time. .

보다 상세하게 설명하면 냉동실(10) 온도는 영하 18도씨 정도를 유지하고, 냉장실(20) 온도는 영상 3도씨 정도를 유지하는 한국을 기준으로 냉기량 조절부재(131)의 위치를 조절하여 쉬라우드 관로 면적(A)을 설정한 냉장고를 냉동실(10) 온도는 영하 18도씨를 유지하고 냉장실 온도(20)는 영상 5도씨 정도를 유지해야 하는 유럽에서 사용할 경우에는 냉기량 조절부재(131)의 한국 설정 위치보다 상측 방향으로 이동시켜 쉬라우드 관로 면적(A)을 줄여 냉장실(20)로 공급되는 냉기의 비를 줄임으로써, 유럽 환경에 맞는 냉기 분배비를 이루어 냉각효율이 향상되는 것이다.In more detail, the freezer compartment 10 maintains a temperature of about 18 degrees Celsius, and the refrigerating compartment 20 adjusts the position of the cool air amount adjusting member 131 based on Korea, which maintains an image of about 3 degrees Celsius. When the refrigerator having a shroud pipe area A is used in Europe, where the freezer compartment 10 maintains a temperature of minus 18 degrees Celsius and the refrigerator compartment temperature 20 maintains an image of about 5 degrees Celsius, the cooling air amount adjusting member 131 In order to reduce the ratio of the cold air supplied to the refrigerating chamber 20 by reducing the shroud pipe area (A) by moving upwards than the Korean set position of the), the cooling efficiency is improved by achieving a cold air distribution ratio suitable for the European environment.
또한, 한국을 기준으로 설정된 냉장고를 냉동실(10) 온도는 영하 15도씨를 유지하고 냉장실(20) 온도는 영상 3도씨를 유지하는 호주에서 사용하는 경우에는 냉기량 조절부재(131)의 한국 설정 위치보다 하측방향으로 이동시켜 쉬라우드 관로 면적(A)을 크게 하여 냉장실(20)로 공급되는 냉기의 비를 늘림으로써, 호주 환경에 맞는 냉기 분배비를 이루어 냉각효율이 향상되는 것이다.In addition, when a refrigerator set based on Korea is used in Australia in which the freezer compartment 10 maintains a temperature of minus 15 degrees Celsius and the refrigerator compartment 20 maintains an image of 3 degrees Celsius, the Korean setting position of the airflow control member 131 By moving downward to increase the shroud pipe area (A) to increase the ratio of the cold air supplied to the refrigerating chamber 20, the cooling efficiency is improved to achieve a cold air distribution ratio for the Australian environment.
이와 같이 본 발명에 의한 냉장고의 냉기공급 조절장치는 가이드레일(132)을 따라 이동하며 쉬라우드 관로 면적(A)을 조절하는 냉기량 조절부재(131)에 의해 냉동실(10) 및 냉장실(20)에 공급되는 냉기분배비를 조절함으로써, 주변 환경에 맞는 냉기분배비를 설정하여 냉각효율이 향상되도록 한 것이다.As described above, the refrigerator air supply control apparatus of the refrigerator according to the present invention moves along the guide rails 132 and is controlled by the freezer amount adjusting member 131 for adjusting the shroud pipe area A. The freezer compartment 10 and the refrigerating compartment 20 are as follows. By adjusting the cold air distribution ratio supplied to the, by setting the cold air distribution ratio according to the surrounding environment to improve the cooling efficiency.
이상에서 살펴본 바와 같이 본 발명에 의한 냉장고의 냉기공급 조절장치는 가이드레일을 따라 이동하며 쉬라우드를 따라 냉기가 안내되도록 형성된 쉬라우드 관로의 면적을 조절하는 냉기량 조절부재를 동작시켜 주변 환경에 따라 쉬라우드 관로의 면적을 조절하여 냉동실 및 냉장실로 공급되는 냉기분배비를 조절함으로써, 다양한 주변환경에 알맞은 냉기분배비를 갖추어 냉장고의 냉각효율이 향상되는 효과가 있다.As described above, the cold air supply control device of the refrigerator according to the present invention operates along a guide rail and operates a cool air amount adjusting member for adjusting an area of a shroud pipe formed to guide cold air along the shroud according to the surrounding environment. By adjusting the area of the shroud pipe to control the cold air distribution ratio supplied to the freezer compartment and the refrigerating compartment, there is an effect that the cooling efficiency of the refrigerator is improved by equipping the cold air distribution ratio suitable for various surrounding environments.
