A refrigerator for detecting efficient external temperature and controlling the operation of the cooling device according to the temperature may be efficient cooling. It relates to a temperature control device and a method thereof.
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 A-A부분을 단면하여 도시한 종단면도로써, 도 1 및 도 2에 도시된 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 냉기안내유로(15)를 통하여 상기 냉장실(20)측으로 안내된다.FIG. 1 is a front view illustrating an internal structure of a conventional refrigerator, and FIG. 2 is a longitudinal cross-sectional view illustrating the AA part of the refrigerator of FIG. 1, and the refrigerator is fixed to the body 1 as shown in FIGS. 1 and 2. It is divided into a freezer compartment 10 and a refrigerating compartment 20 by a partition wall 16 mounted at a site. Looking at the cold air supply structure, the refrigerant having low temperature and low pressure is heat exchanged and cooled in an evaporator 3 passing through the inside. Part of the cold air is forcedly blown by the blower fan 13 and supplied to the freezing chamber 10 through the shroud 14, and a part of the remaining cold air falls freely through the shroud 14 It is guided to the refrigerating compartment 20 side through the cold air flow passage 15.
상기 냉장실(20)로의 냉기 공급은 상기 본체(1)의 후방에 길이 방향으로 형성되며 상기 쉬라우드(14)와 상기 냉장실(20)을 연결하는 냉기안내유로(15)를 통해 냉기가 자유낙하 하면서, 상기 냉기안내유로(15)의 전면에 형성된 다수개의 토출구(15a)를 통하여 상기 냉장실(20)로 공급되도록 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, while the cold air is freely dropped through the cold air guide passage 15 connecting the shroud 14 and the refrigerating chamber 20. It is configured to be supplied to the refrigerating chamber 20 through a plurality of discharge ports (15a) formed on the front surface of the cold air guide flow path (15).
이와 같은 과정을 통하여 상기 냉동실(10) 및 냉장실(20)에 공급된 냉기는 내부에 적재된 음식물을 냉각시킨 후, 상기 분리벽(16)의 내부에 형성된 냉기흡입유로(16a)를 통해 다시 증발기(3) 부근으로 재 유입되어 재 냉각된다.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 cold air suction passage 16a formed in the separation wall 16. (3) It reflows in the vicinity and is recooled.
또한, 상기 냉장실(20)의 내부에는 냉장실온도센서(21)가 장착되고, 상기 냉장실온도센서(21)에 의해 측정된 상기 냉장실(20) 내부의 온도가 설정온도 이하가 되면, 상기 냉동실(10) 및 냉장실(20)의 내부를 냉각하는 냉각장치를 작동시키고, 상기 증발기(3)를 통해 냉기가 공급되는 것이다.In addition, a refrigerator compartment temperature sensor 21 is mounted inside the refrigerator compartment 20, and when the temperature inside the refrigerator compartment 20 measured by the refrigerator compartment temperature sensor 21 is lower than or equal to a set temperature, the freezer compartment 10 is provided. ) And a cooling device for cooling the inside of the refrigerating chamber 20, and cold air is supplied through the evaporator 3.
