Abstract
Description
본 발명은 냉장고에 관한 것으로서, 보다 상세하게는 냉동 냉장실 내에서 냉기의 유동/확산이 고르게 이루어짐으로써 보다 효율적인 냉각작용을 수행할 수 있는 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of performing a more efficient cooling operation by making the flow / diffusion of cold air even in the freezer compartment.
냉장고는 음식물 등을 냉동시키거나, 냉장보관하기 위해 사용되는 것으로서, 도 1에 나타난 것과 같이 그 내부에 냉동실(10a)과 냉장실(10b)로 분리된 수납공간을 형성하는 케이스(10) 및 상기 케이스(10)의 일측에 장착되어 냉동실(10a)과 냉장실(10b)을 개폐하는 냉동 냉장실 도어(11)(12)와, 압축기(20), 응축기(30) 및 증발기(40) 등과 같이 냉동사이클을 이루어 냉기를 형성하는 기기들을 포함하여 구성되어 있다.The refrigerator is used to freeze or refrigerate food or the like, and as shown in FIG. 1, a case 10 and a case forming a storage space divided into a freezing compartment 10a and a refrigerating compartment 10b therein. Refrigeration cycle doors 11 and 12 mounted on one side of the refrigerator 10 to open and close the freezing compartment 10a and the refrigerating compartment 10b, and a refrigeration cycle such as a compressor 20, a condenser 30, an evaporator 40, and the like. It is configured to include devices that form cold air.
이러한 냉장고에서는 압축기(20)에 의해 저온 저압의 기상 냉매가 고온 고압으로 압축되고, 압축된 고온 고압의 기상 냉매가 응축기(30)를 지나는 과정에서 냉각 응축되어 고압의 액상으로 전환되며, 고압의 액체상태로 된 냉매는 모세관(미도시)을 통과하면서 그 온도와 압력이 낮아진 다음, 계속해서 증발기(40)에서 저온 저압의 기체상태로 변하면서 주위로부터 열을 빼앗아 그 주위의 공기를 냉각시키게 된다. 증발기(40)를 거쳐 냉각된 공기는 증발기(40) 일측에 위치된 송풍팬(42)의 작동으로 냉동, 냉장실(10a)(10b)로 유입 순환됨으로써 냉동실(10a) 및 냉장실(10b)의 온도가 낮아지게 된다.In such a refrigerator, the low-temperature low-pressure gaseous refrigerant is compressed to high temperature and high pressure by the compressor 20, and the compressed high-temperature high-pressure gas phase refrigerant is cooled and condensed while passing through the condenser 30 to be converted into a high-pressure liquid phase, and the high-pressure liquid The refrigerant in the state passes through a capillary tube (not shown), and its temperature and pressure are lowered. Then, the refrigerant is changed into a gaseous state of low temperature and low pressure in the evaporator 40 to take heat from the surroundings to cool the air around it. The air cooled through the evaporator 40 is introduced into the freezing and refrigerating chambers 10a and 10b by the operation of the blower fan 42 located on one side of the evaporator 40, thereby circulating the temperature of the freezing chamber 10a and the refrigerating chamber 10b. Will be lowered.
한편, 냉장고에는 증발기(40) 주위에서 형성된 냉기의 순환을 위한 냉기 순환유로가 형성되어 있는데, 상기 냉기 순환유로는 냉동실(10a)에 형성된 송풍구 및 냉장실(10b)의 후면과 측면에 구성된 냉기덕트(50)를 중심으로 이루어져 있다.On the other hand, the refrigerator is formed with a cold air circulation passage for circulation of the cold air formed around the evaporator 40, the cold air circulation flow path formed in the rear and side of the ventilation port and the refrigerating chamber (10b) formed in the freezer compartment (10a) ( 50).
이와 같은 냉기 순환유로에 의하면 증발기(40) 주위에서 형성된 냉기가 송풍팬(42)에 의해 냉동실(10a)로 유입되고, 냉동실(10a)로 유입된 냉기는 냉동실(10a) 내부를 순환한 다음 증발기(40) 측으로 향하게 되며, 냉기의 일부는 냉기덕트(50)를 통해 이송되어 냉장실(10b)로 배출된다.According to the cold air circulation passage as described above, the cold air formed around the evaporator 40 flows into the freezing compartment 10a by the blower fan 42, and the cold air introduced into the freezing compartment 10a circulates inside the freezing compartment 10a and then the evaporator. 40, the portion of the cold air is transferred through the cold air duct 50 is discharged to the refrigerating chamber (10b).
냉장실(10b)로 유입된 냉기는 냉장실(10b) 내부를 순환한 다음 다시 냉기덕트(50)로 유입되어 냉동실(10a)로 이송되고, 송풍팬(42)에 의해 증발기(40)를 거치는 순환작동을 반복적으로 진행하게 된다.The cold air introduced into the refrigerating compartment 10b circulates inside the refrigerating compartment 10b, and then flows back into the cold air duct 50, is transferred to the freezing compartment 10a, and passes through the evaporator 40 by the blowing fan 42. Will be repeated repeatedly.
상술한 바와 같은 종래기술에 의하면 비교적 단순한 구조의 냉기덕트(50)를 통해 냉동실(10a)의 냉기를 냉장실(10b)로 이송하고, 다시 냉동실(10a)로 순환시키는 작용을 이행할 수 있기 때문에 냉장고의 구조 단순화를 이룰 수 있다는 특징이 있다.According to the related art as described above, since the cold air of the freezer compartment 10a is transferred to the refrigerating compartment 10b through the cold air duct 50 having a relatively simple structure, the refrigerator can be circulated to the freezer compartment 10a. It is characterized by the fact that the structure can be simplified.
그러나, 이와 같은 종래기술에 의하면 냉장실(10b)의 후면 및 측면에 형성된 냉기덕트(50)의 통풍구(50a)를 통해 냉장실(10b)로 유입된 냉기가 냉장실(10b)을 순환한 다음 다시 상기 통풍구(50a)를 통해 냉동실(10a)로 순환하기 때문에 통풍구(50a)에서 떨어진 부분과 가까운 부분의 온도차이가 심해지며, 특히 통풍구(50a)와 멀리 떨어진 냉장실 도어(12) 근처에는 냉기가 제대로 도달하지 않게 된다.However, according to the related art, the cold air introduced into the refrigerating compartment 10b through the air vent 50a of the cold air duct 50 formed on the rear and side surfaces of the refrigerating compartment 10b circulates through the refrigerating compartment 10b, and then again the vent. Because of the circulation to the freezer compartment (10a) through the (50a), the temperature difference between the portion and the portion away from the vent 50a is intensified, in particular, the cold air does not reach properly near the refrigerator compartment door (12) far away from the vent (50a) Will not.
이러한, 소위 온도편차 현상은 냉장실(10b)뿐만 아니라 냉동실(10a)에서도 마찬가지로 발생하게 된다.This so-called temperature deviation phenomenon occurs not only in the refrigerating chamber 10b but also in the freezing chamber 10a.
따라서, 이와 같은 종래기술에 의하면 냉동 냉장실(10a)(10b)내 온도편차가심할 뿐만 아니라, 도어 바스켓(14)에 보관된 음식물에 대한 냉각작용이 제대로 이루어지지 않는 등, 결과적으로 냉장고의 전체적인 냉각작용이 저하된다는 문제점이 발생한다.Therefore, according to the related art, not only the temperature deviation in the freezer compartments 10a and 10b is severe, but also the cooling action on the food stored in the door basket 14 is not properly performed. The problem is that the action is degraded.
본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 냉기덕트의 통풍구를 통해 냉장실로 유입된 냉기가 도어측으로 흐르게 함으로써 균일한 냉기 분산효과를 얻을 수 있으며, 이로 인해 냉장고의 냉각작용이 효율적으로 이루어지도록 하는 냉장고의 냉기순환 유로구조의 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, it is possible to obtain a uniform cold air dispersion effect by allowing the cold air introduced into the refrigerating chamber through the ventilation holes of the cold air duct flows to the door side, thereby making the cooling operation of the refrigerator efficient It is an object of the present invention to provide a cold air flow passage structure of a refrigerator to be prepared.
