Description
본 발명은 냉장고의 냉기 공급장치에 관한 것으로서, 보다 상세히 설명하면 냉장실을 냉각하는 냉기의 공급과 냉장실 내에서의 냉기 순환이 원활하게 이루어지도록 하여 냉각효율을 높일 수 있는 냉장고의 냉기 공급장치에 관한 것이다.The present invention relates to a cold air supply device for a refrigerator, and more particularly, to a cold air supply device for supplying cold air to cool a refrigerating compartment and smoothing the cold air circulation in the refrigerating compartment to increase cooling efficiency. .
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 교환 되어 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 덕트(15)를 통하여 상기 냉장실(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. Divided into the freezing compartment 10 and the refrigerating compartment 20 by the partition wall 16, and looks at the cold air supply structure, a portion of the cold air cooled by heat exchange in the evaporator (3) through which the low-temperature low-pressure refrigerant passes through 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, thereby allowing the duct 15 It is guided to the refrigerating chamber 20 side through.
상기 냉장실(20)로의 냉기 공급은 상기 본체(1)의 후방에 길이 방향으로 형성되며 상기 쉬라우드(14)와 상기 냉장실(20)을 연결하는 덕트(15)를 통해 냉기가 자유낙하 하면서, 상기 덕트(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, and the cold air is freely dropped through the duct 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 duct 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 흡입로(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 suction passage 16a formed in the separation wall 16. 3) It is reintroduced to the vicinity and recooled.
그러나, 상기와 같은 종래의 냉장고에 있어서, 상기 냉장실(20)의 토출구(15a) 주위에 보관된 음식물은 저온의 냉기와 직접 접촉하게 되어 냉해를 입는 경우가 발생되기도 하고, 식품의 변질을 초래하기도 한다.However, in the conventional refrigerator as described above, the food stored around the discharge port 15a of the refrigerating chamber 20 is in direct contact with the low temperature cold and may cause cold damage, and may cause food to be deteriorated. do.
이와는 달리 상기 토출구(15a)에서 멀리 위치한 음식물은 적정하게 냉각되지 않게 되어 불 균일한 온도분포로 인해 냉각 효율이 저하되는 문제점이 발생하게 된다.On the contrary, the food located far from the discharge port 15a is not cooled properly, resulting in a problem that cooling efficiency is lowered due to uneven temperature distribution.
상기한 바와 같은 점을 감안하여 안출한 본 발명의 목적은 냉장실에 냉기가 고르게 공급되고, 공급된 냉기가 원활히 유동되어 냉각효율을 높일 수 있는 냉장고의 냉기 공급장치를 제공함에 있다.An object of the present invention devised in view of the above point is to provide a cold air supply apparatus of a refrigerator which is evenly supplied with cold air to the refrigerating chamber, and the supplied cold air flows smoothly to increase the cooling efficiency.

After the freezing, a part of the remaining cold air is guided to the shroud 14 and free-falled to guide a certain portion of the right side of the refrigerating compartment 20 through the discharge side vertical duct 23c, and then to the shelf 22. Guided through the discharge side horizontal duct (23b) formed in each refrigerator compartment compartment formed by the guided cold air evenly in each compartment of the refrigerator compartment 20 through the discharge port (23a) formed in communication with the discharge side horizontal duct (23b). Discharged.
