본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 고내 냉기를 흡입하는 흡 입구의 구조를 개선하여 도어 수납실에 수납된 식품의 약냉 현상을 방지할 수 있는 냉장고에 관한 것이다. The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of preventing a weak cooling phenomenon of food stored in a door storage chamber by improving a structure of a suction inlet for sucking cold air therein.

냉장고는 식품의 저온저장을 목적으로 하는 장치로서, 냉동사이클을 구성하는 증발기에서 열교환된 냉기를 이용하여 각종 식품을 장기간 신선하게 유지할 수 있도록 한 것이다. The refrigerator is an apparatus for low temperature storage of food, and is used to keep various foods fresh for a long time by using cold air heat exchanged in an evaporator constituting a refrigeration cycle.

일반적으로 냉장고는 음식물 등을 저장하기 위해 전면이 개방된 저장실이 형성된 본체와, 개방된 저장실을 개폐하기 위해 본체에 회동 가능하게 설치된 도어에 의해 외관을 형성한다. 저장실 내부에는 음식물 등을 지지하는 선반에 의해 복수의 저장공간으로 구획되며, 도어 내측에는 음료수 및 간단한 음식물 등을 수납할 수 있는 다수의 수납실이 형성된다.In general, the refrigerator is formed by a main body having a storage compartment having an open front surface for storing food and the like, and a door rotatably installed in the main body to open and close the open storage compartment. The storage compartment is partitioned into a plurality of storage spaces by shelves for supporting food and the like, and a plurality of storage compartments for storing beverages and simple foods are formed inside the door.

저장실 내측 후방에는 저장실 내부공간을 냉각시키기 위해 냉기를 생성하는 증발기와, 증발기 상부에 설치되어 증발기에서 생성된 냉기를 송풍력에 의해 강제로 순환시키는 송풍팬이 설치된 냉기생성실이 형성된다.The inside of the storage compartment is formed with an evaporator for generating cold air to cool the internal space of the storage compartment, and a cold air generating chamber provided with a blower fan installed in the upper part of the evaporator forcibly circulating the cold air generated by the evaporator by the blowing force.

또한, 저장실 내측 후방에는 냉기생성실 상부에 형성되며 그 하단이 냉기생성실과 연통되고 그 전면에는 저장실로 냉기를 토출하는 다수의 냉기토출구가 형성된 냉기토출덕트와, 냉기생성실 주위에 형성되며 저장실로 토출된 냉기를 흡입하는 다수의 냉기흡입구가 형성된 냉기흡입덕트가 설치된다.In addition, a cold air discharge duct formed at an upper side of the cold air generating chamber at a rear side of the storage chamber and having a plurality of cold air discharge ducts communicating with the cold air generating chamber at the bottom thereof and discharging the cold air to the storage chamber at the front side thereof, and formed around the cold air generating chamber. The cold air suction duct is provided with a plurality of cold air suction ports for sucking the discharged cold air.

이러한 구성을 갖는 냉장고의 냉기순환구조를 살펴보면, 증발기에서 생성된 냉기는 송풍팬의 송풍력에 냉기토출덕트로 상승하면서 저장실 후면에 형성된 냉기토출구에 의해 저장실의 후방에서 도어 측으로 토출되고, 도어 측으로 토출된 냉기 는 저장실 후면에 마련된 냉기흡입구로 흡입된 후 냉기흡입덕트를 증발기로 유입되는 순환을 반복하면서 저장실의 음식물 등을 냉장 및 냉동시킨다.Looking at the cold air circulation structure of the refrigerator having such a configuration, the cold air generated in the evaporator is discharged to the door side from the rear of the storage compartment by the cold air outlet formed at the rear of the storage compartment while rising to the cold air discharge duct on the blowing force of the blower fan, and discharged to the door side. The cold air is sucked into the cold air inlet provided at the rear of the storage compartment, and then the foods in the storage compartment are refrigerated and frozen while repeating the circulation of the cold air suction duct into the evaporator.

그러나, 상기와 같은 냉기순환구조에서는 냉기흡입구와 냉기토출구가 모두 저장실 후면에 위치하게 되어 저장실 전면부분, 즉 도어 측 부근의 냉기의 유동은 매우 약하여 거의 정체되어 있게 된다. 특히 저장실 내부의 도어 주위는 도어와 본체 사이의 가스켓 부위를 통한 외부 공기의 유입이 매우 큰 영역으로 냉장 또는 냉동효과가 매우 불리한 영역이어서, 도어의 수납실에 보관된 음료 및 식품 등은 상대적으로 냉기의 영향을 받지 못하게 되어 약냉되는 현상이 발생되는 문제점이 있다.However, in the cold air circulation structure as described above, both the cold air inlet and the cold air outlet are located at the rear side of the storage compartment, and thus the flow of cold air near the front side of the storage compartment, that is, the door side, is almost stagnant. In particular, the area around the door inside the storage compartment is a region where the inflow of outside air through the gasket between the door and the main body is very large, and the refrigeration or freezing effect is very disadvantageous, so that beverages and foods stored in the storage compartment of the door are relatively cold. There is a problem that is not affected by the weak cooling phenomenon occurs.

또한, 냉기흡입구와 냉기토출구가 모두 동일한 벽면에 형성되어 있으므로 냉기토출구에서 토출된 냉기가 저장실 내부를 골고루 순환하지 못하고 바로 냉기흡입구로 흡입될 수 있어 저장실 내의 음식물 등을 충분히 냉각시킬 수 없어 냉각효율이 떨어지는 문제점이 있다. In addition, since both the cold air inlet and the cold air outlet are formed on the same wall surface, the cold air discharged from the cold air outlet can not be circulated evenly inside the storage compartment and can be sucked directly into the cold air inlet so that the food in the storage compartment can not be cooled sufficiently, thus cooling efficiency is improved. There is a problem falling.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 냉기토출구로 토출되는 냉기를 저장실 내부 전체로 골고루 공급하여 냉각효율을 향상시킴과 동시에, 도어 수납실에 보관된 식품의 약냉 현상을 방지할 수 있는 냉장고를 제공하는 것이다. The present invention is to solve such a problem, an object of the present invention to improve the cooling efficiency by supplying evenly the cold air discharged to the cold air outlet throughout the storage compartment, and at the same time to reduce the weak cooling phenomenon of the food stored in the door storage chamber It is to provide a refrigerator that can prevent.

In order to achieve the above object, the refrigerator includes a main body in which a storage compartment is formed, a door in which a plurality of storage chambers are formed to open and close the storage compartment and store beverages, and an evaporator installed behind the storage compartment to generate cold air. And a cold air outlet formed in a rear wall of the storage compartment for supplying cold air generated from the evaporator to the storage compartment, and a cold air inlet for guiding inflow of the cold air discharged into the storage compartment to the evaporator. The suction port is formed on the side wall of the storage compartment adjacent to the door.

All of the cold air discharged from the to be discharged to the refrigerating chamber door (30) side.

이는 냉기흡입구를 냉장실(R) 측벽의 후방이나 중앙에 형성하면 냉기토출구(43)에서 토출되는 냉기 중 일부가 냉장실도어(30) 측에 도달하기 전에 냉기흡입구로 흡입되어, 도어수납실(31)에 보관된 음료 등에 도달되는 전체 냉기의 양이 줄어들기 때문에, 이로 인한 도어수납실(31)의 약냉 현상이 발생되는 것을 방지하기 위함이다. When the cold air inlet is formed at the rear or the center of the side wall of the refrigerating chamber R, some of the cold air discharged from the cold air discharge port 43 is sucked into the cold air inlet before reaching the refrigerating chamber door 30, and the door storage chamber 31 is formed. Since the total amount of cold air reached in the beverage or the like stored therein is reduced, thereby preventing the weak cooling phenomenon of the door storage chamber 31 from occurring.
