It relates to a cold air supply control device of the refrigerator.

본 발명은 냉장고의 냉기공급 조절장치에 관한 것으로서, 보다 상세히 설명하면 냉장실 및 냉동실에 장착된 센서에 의하여 자동으로 상기 냉장실에 공급되는 냉기의 유량을 조절하는 냉장고의 냉기공급 조절장치에 관한 것이다.The present invention relates to a cold air supply control device for a refrigerator, and more particularly, to a cold air supply control device for controlling a flow rate of cold air supplied to the refrigerator compartment by a sensor mounted in the refrigerator compartment and the freezer compartment.

일반적으로 냉장고는 제빙용기 및 냉동식품을 설정된 온도 하에서 보관하기 위한 냉동실과 냉장 대상물이 수납되는 냉장실로 구획되어 있으며, 내부에 냉동사이클장치가 설치되어 압축, 응축, 팽창, 증발의 냉동사이클로 순환되고, 순환회로중 증발기에서 외부의 열을 흡수하는 것을 이용하여 내부를 냉동, 냉장 상태로 유지하는 것이다.In general, the refrigerator is divided into a freezer compartment for storing ice-making containers and frozen foods at a set temperature, and a refrigerating compartment in which refrigeration objects are stored, and a refrigeration cycle device is installed therein to circulate the refrigeration cycle of compression, condensation, expansion, and evaporation. 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 정면도이고, 도 2는 도 1의 냉장고의 내부구조를 보인 측면도로써, 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 냉 장실(20)측으로 안내된다.1 is a front view illustrating an internal structure of a conventional refrigerator, and FIG. 2 is a side view illustrating an internal structure of the refrigerator of FIG. 1, and as shown in FIGS. 1 and 2, the refrigerator is mounted at a predetermined portion of the main body 1. The freezing chamber 10 and the refrigerating chamber 20 are divided and partitioned by the separating wall 16. Looking at the cold air supply structure, a part of the cold air cooled by heat exchange in the evaporator 3 through which the low temperature and low pressure refrigerant passes through Is forcedly blown by the blower fan 13 to be supplied to the freezing chamber 10 through a shroud 14, and a part of the remaining cold air is freely dropped through the shroud 14 so as to refrigerate the cold air guide flow path. It is guided to the refrigerating chamber 20 side through (15).

상기 냉장실(20)로의 냉기공급은 상기 본체(1)의 후방에 길이 방향으로 형성되며 상기 쉬라우드(14)와 상기 냉장실(20)을 연결하는 냉장실 냉기안내유로(15)를 통해 냉기가 자유낙하하고, 냉기안내유로(15)를 통해 자유 낙하된 냉기는 냉장실 냉기안내유로(15)에 접하는 냉장실 배면에 형성된 다수개의 냉장실 토출구(15a)를 통하여 상기 냉장실(20)로 공급되어 상기 냉장실(20) 내부를 냉각하도록 구성되어 있다.The cold air supply to the refrigerating chamber 20 is formed in the longitudinal direction at the rear of the main body 1, and the cold air is freely dropped through the refrigerating chamber cold air guide passage 15 connecting the shroud 14 and the refrigerating chamber 20. The cold air freely dropped 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. 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. .

그러나, 상기한 바와 같이 종래 구조로 구성된 냉장고에 있어서는 상기 증발기(34)에서 발생된 냉기가 상기 냉동실(10) 및 냉장실(20)에 분배되는 비율인 냉기 분배비가 미리 설정된 상태이므로, 주위 온도에 따라 상기 냉동실(10) 및 냉장실(20)의 내부 온도가 크게 변화될 시, 즉 겨울철과 같이 주위 온도가 장시간 동안 5~15도 이하일 시, 상기 압축기(31)의 운전률이 현저히 떨어져, 상기 냉동실(10)의 약냉이 발생되는 문제점이 발생된다.However, in the refrigerator having the conventional structure as described above, since the cold air distribution ratio, which is the ratio at which cold air generated in the evaporator 34 is distributed to the freezer compartment 10 and the refrigerating compartment 20, is set in advance, When the internal temperature of the freezer compartment 10 and the refrigerating compartment 20 is greatly changed, that is, when the ambient temperature is 5 to 15 degrees or less for a long time, such as in winter, the operation rate of the compressor 31 is significantly lowered. There is a problem that the weak cooling of 10) occurs.

상기와 같은 점을 감안하여 안출한 본 발명의 목적은 주위 환경의 변화에 따라 냉장실 및 냉동실에 공급되는 냉기 분배비를 조절하여 냉각효율을 향상시킬 수 있도록 하는 냉장고의 냉기공급 조절장치를 제공함에 있다. An object of the present invention devised in view of the above point is to provide a refrigerator air supply control device for improving the cooling efficiency by adjusting the distribution ratio of cold air supplied to the refrigerating chamber and the freezing chamber according to the change of the surrounding environment.

Stops and maintains that state.

그리고, 겨울철과 같이 주위 온도가 장시간 동안 5~15도 이하를 유지하여 상기 압축기의 운전률이 현저히 떨어져 냉동실(10)의 약냉이 발생될 시에는 냉동실(10) 내부로 노출된 회전판(33)을 회전시켜 회전축(32)에 형성된 댐퍼판(31)을 일정각도로 회전되도록 하여 상기 냉기안내유로(15)의 단면적을 줄임으로써, 냉장실(20)에 공급되는 냉기의 양을 줄이고, 냉동실(10)에 공급되는 냉기의 양을 늘려 냉동실(10)의 약냉을 방지할 수 있게 된다. 상기 회전판(33)의 회전각도에 따라 사용자가 상기 냉기안내유로(15)를 통해 냉기가 안내되는 냉기량을 인식할 수 있도록 일정한 표시를 해 두어도 무방하다.In addition, when the ambient temperature is maintained at 5 ° C. to 15 ° C. or less for a long time, such as in winter, when the operation rate of the compressor is significantly lowered, and the cooling of the freezer compartment 10 occurs, the rotating plate 33 exposed into the freezer compartment 10 is opened. Rotating the damper plate 31 formed on the rotating shaft 32 by a predetermined angle to reduce the cross-sectional area of the cold air guide flow path 15, thereby reducing the amount of cold air supplied to the refrigerating chamber 20, freezer compartment 10 It is possible to prevent the weak cooling of the freezer compartment 10 by increasing the amount of cold air supplied to the freezer compartment. According to the rotation angle of the rotating plate 33, the user may be given a constant display so that the user can recognize the amount of cold air is guided through the cold air flow path 15.

이와 같이 본 발명에 의한 냉장고의 냉기공급 조절장치는 냉동실(20)에 냉기가 공급되도록 안내하는 냉기안내유로(15)의 내부에 장착된 냉기공급 조절부재(30)를 작동시켜 외부조건에 따라 냉기안내유로(15)를 통해 냉장실(20)로 공급되는 냉 기의 량을 조절함으로써, 겨울철과 같이 압축기의 운전률이 현저히 떨어질 시, 냉동실(10)으로 공급되는 냉기의 량을 늘려 약냉이 발생되는 것을 방지하게 된다.Thus, the cold air supply control device of the refrigerator according to the present invention operates the cold air supply control member 30 mounted inside the cold air guide flow path 15 for guiding cold air to be supplied to the freezer compartment 20 according to external conditions. By adjusting the amount of cold air supplied to the refrigerating compartment 20 through the guide passage 15, when the operation rate of the compressor is significantly lowered, such as in winter, the amount of cold air supplied to the freezing compartment 10 is increased to generate weak cooling. Will be prevented.
