Description

입체 냉각방식 냉장고{REFRIGERATOR WITH MULTIPLE COOLING SYSTEM}REFRIGERATOR WITH MULTIPLE COOLING SYSTEM}

본 발명은 냉장고에 관한 것으로서, 보다 상세하게는 냉장실 도어 측에서의 냉기토출을 위한 도어덕트가 다중형으로 구성된 입체 냉각방식 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a three-dimensional cooling type refrigerator in which a door duct for discharging cold air from the refrigerating chamber door side is formed in a multiple type.

냉장고는 음식물 등을 냉동시키거나, 냉장보관하기 위해 사용되는 것으로서, 그 내부에 냉동실과 냉장실로 분리된 수납공간을 형성하는 케이스 및 상기 케이스의 일측에 장착되어 냉동실과 냉장실을 개폐하는 냉동실 및 냉장실 도어와, 압축기, 응축기 및 증발기 등과 같이 냉동사이클을 이루어 냉동실과 냉장실의 온도를 낮추기 위한 기기들을 포함하여 구성되어 있다.The refrigerator is used to freeze or refrigerate food and the like, and includes a case forming a storage space separated into a freezer compartment and a refrigerating compartment, and a freezer compartment and a refrigerator compartment door installed at one side of the case to open and close the freezer compartment and the refrigerating compartment. And, by forming a refrigeration cycle, such as a compressor, condenser and evaporator is configured to include a device for lowering the temperature of the freezer compartment and the refrigerating compartment.

그리고, 이와 같은 냉장고의 냉각방식은 케이스 내에 구성된 냉기유로의 형태에 따라 단일 냉각방식과 입체 냉각방식으로 구분되는데, 단일 냉각방식은 냉기덕트가 케이스의 후면에만 구성됨으로써 냉기가 일측에서 집중 토출되는 방식이며, 입체 냉각방식은 냉기덕트가 케이스의 삼면에 고루 배치될 뿐만 아니라, 냉장실 도어에도 배치되어 냉기유로가 입체적으로 냉장실의 냉각공간을 둘러쌈으로써 냉기의 토출이 여러 방향에서 이루어지는 방식이다.In addition, the cooling method of such a refrigerator is divided into a single cooling method and a three-dimensional cooling method according to the shape of the cold air flow path configured in the case. In the single cooling method, the cold air duct is formed only at the rear of the case, where the cold air is concentrated at one side. In the three-dimensional cooling method, the cold air duct is not only evenly disposed on three sides of the case, but is also disposed in the refrigerating chamber door so that the cold air flow passage surrounds the cooling space of the refrigerating compartment three-dimensionally, thereby discharging the cold air in various directions.

상기 입체 냉각방식에 의하면 냉기의 토출이 여러 방향에서 이루어짐으로써 냉각공간내의 온도가 고르게 유지되기 때문에 단일 냉각방식에 비해 고내에 저장된 식품이 비교적 고르게 냉각된다.According to the three-dimensional cooling method, since the temperature of the cooling space is maintained evenly by discharging the cold air in various directions, the food stored in the refrigerator is relatively evenly cooled compared to the single cooling method.

한편, 이러한 입체 냉각방식의 냉장고에서 냉장실 도어 측으로 구성된 냉기유로는 도 1에 나타난 것과 같이 케이스(10) 측면에 구성된 냉장실 덕트(12)와 연계되도록 냉장실 도어(20)에 구비된 도어덕트(22)로 이루어져 있는데, 상기 도어덕트(22)는 냉장실 도어(20)가 닫힌 상태에서 냉장실 덕트(12) 선단의 냉기연결구(12a)와 접하는 냉기유입구(22a)가 그 선단에 형성되며, 중간에 냉기의 토출을 위한 냉기배출구(22b)가 형성된 구조로 이루어져 있다. 여기서, 상기 도어덕트(22)는 대략 냉장실 도어(20)의 대략 상부에 위치되어 있으며, 냉기배출구(22b)는 냉기의 배출방향이 아래를 향하도록 형성되어 있다.On the other hand, in the three-dimensional cooling method of the refrigerator air passage configured as the refrigerator compartment door side as shown in Figure 1 door duct 22 provided in the refrigerator compartment door 20 to be associated with the refrigerator compartment duct 12 configured on the side of the case 10 The door duct 22 has a cold air inlet 22a contacting the cold air connector 12a at the tip of the refrigerator compartment duct 12 in a state in which the refrigerator compartment door 20 is closed, and the cold air inlet 22a is formed at the front end thereof. It consists of a structure in which the cold air discharge port 22b for discharge is formed. Here, the door duct 22 is located approximately at the top of the refrigerating compartment door 20, the cold air outlet 22b is formed so that the discharge direction of the cold air is directed downward.

이와 같은 입체 냉각방식의 냉장고에 의하면 냉장실 도어(20)가 닫힌 상태에서 도어덕트(22)의 냉기유입구(22a)가 냉장실 덕트의 냉기연결구(12a)와 밀착됨으로써 증발기(E)에서 송풍되는 냉기(도면상 화살표시)가 냉장실 덕트(12)로부터 도어덕트(22)에 까지 이송되며, 이와 같이 이송된 냉기가 냉기배출구(22b)를 통해 도어덕트(22)의 하방에 위치된 도어 바스켓(24) 측으로 집중 배출됨으로써 냉장실에 대한 입체냉각 효과와 함께 상기 도어 바스켓(24)에 수납된 식품을 빠르게 냉각시키는 효과를 얻게 된다.According to the three-dimensional cooling method of the refrigerator, the cold air inlet 22a of the door duct 22 is in close contact with the cold air connector 12a of the refrigerating chamber duct while the refrigerating compartment door 20 is closed. Arrow in the drawing) is conveyed from the refrigerating chamber duct 12 to the door duct 22, the cold air thus conveyed through the cold air outlet 22b, the door basket 24 located below the door duct 22 By intensively discharging to the side, a three-dimensional cooling effect on the refrigerating chamber is obtained, and an effect of rapidly cooling the food stored in the door basket 24 is obtained.

그러나, 상술한 바와 같은 종래기술에 의하면 도어덕트(22)가 냉장실 도어(20)의 상부측으로 치우쳐 설치되어 있기 때문에 상기 도어덕트(22)에서 배출되는 냉기가 일측으로 편중됨으로써 도어덕트(22)와 근접한 도어 바스켓(24)에 보관된 식품이 과냉각될 뿐만 아니라, 냉장실 내의 온도편차가 심해짐으로써 고른 냉각 작용이 이루어지지 않는다는 문제점이 발생한다.However, according to the related art as described above, since the door duct 22 is installed to the upper side of the refrigerating compartment door 20, the cold air discharged from the door duct 22 is biased toward one side, so that the door duct 22 Not only the food stored in the adjacent door basket 24 is supercooled, but also the temperature difference in the refrigerating compartment is increased, which causes a problem of even cooling.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 냉장실 도어 측에서 고르게 냉기가 배출됨으로써 냉장실 도어에 수납된 음식물의 과냉각을 방지하고, 냉각공간의 온도편차를 줄일 수 있는 입체 냉각방식 냉장고의 제공을 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and provides a three-dimensional cooling method of a refrigerator which can prevent overcooling of food stored in the refrigerating compartment door by reducing cold air evenly from the refrigerating compartment door side, and reduce the temperature deviation of the cooling space. For the purpose.

이하, 본 발명의 실시예를 첨부된 도 2를 참조로 하여 상세하게 설명하며, 본 발명의 내용 중 종래구성과 동일한 부분에 대해서는 동일한 부호를 부여하기로 한다.DETAILED DESCRIPTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the same reference numerals will be given to the same parts as those in the prior art.

본 발명의 실시예에 따른 입체 냉각방식 냉장고는 냉장실을 구성하는 케이스 내에 구성되어 증발기로 부터 송풍되는 냉기의 유로를 형성하는 냉장실 덕트와, 상기 냉장실 덕트와 연결되어 냉장실 도어의 각부분에서 고른 냉기토출이 가능토록하는 다중 덕트수단을 포함하여 이루어진다.The three-dimensional cooling method refrigerator according to an embodiment of the present invention is a refrigerator compartment duct formed in a case constituting the refrigerator compartment to form a flow path of cold air blown from the evaporator, and connected to the refrigerator compartment duct and selected at each part of the refrigerator compartment door. This may comprise multiple duct means.

여기서, 상기 다중 덕트수단은 도면에 나타난 것과 같이 냉장실 덕트(22)와 분리 가능하게 연결되는 상부 도어덕트(30)와, 상기 상부 도어덕트(30)의 하방에 소정의 간격을 두고 구비되는 하부 도어덕트(32)와, 상기 상 하부 도어덕트(30)(32)를 통기 가능하게 연결하는 냉기 분배덕트(34)로 이루어지는데, 상기 각 도어덕트(30)(32)는 그 중간에 공히 냉기배출구(30a)(32a)가 형성된 구조로 이루어진다.Here, the multiple duct means is an upper door duct 30 which is detachably connected to the refrigerating chamber duct 22 as shown in the drawing, and a lower door provided at a predetermined distance below the upper door duct 30. It consists of a cold air distribution duct 34 for connecting the duct 32 and the upper and lower door ducts 30 and 32 to be ventilated, wherein each door duct 30, 32 is a cold air outlet in the middle. 30a and 32a are formed.

더불어, 상기 상부 도어덕트(30)의 선단에는 냉장실 도어(20)가 닫힌 상태에서 냉장실 덕트(12)의 냉기연결구(12a)와 분리 가능하게 밀착되는 냉기유입구(30b)가 구비된다.In addition, the tip of the upper door duct 30 is provided with a cold air inlet (30b) that is in close contact with the cold air connector (12a) of the refrigerating chamber duct 12 in a closed state of the refrigerating compartment door (20).

상술한 바와 같이 구성된 본 실시예에 따른 입체 냉각방식 냉장고에 의하면 냉장실 도어(20)가 닫힌 상태에서 냉장실 덕트(12)와 상부 도어덕트(30)가 냉기연결구(12a)와 냉기유입구(30b)의 접속을 통해 연결됨으로써, 상기 상부 도어덕트(30)로 냉기가 유입되는데, 이와 같이 상부 도어덕트(30)로 유입된 냉기는 냉기배출구(30a)를 통해 배출됨과 동시에, 냉기 분배덕트(34)를 통해 그 일부가 하부 도어덕트(32) 측으로 유입되어, 상기 하부 도어덕트(32)의 냉기배출구(32a)를 통해 배출된다.According to the three-dimensional cooling type refrigerator according to the present embodiment configured as described above, the refrigerating compartment duct 12 and the upper door duct 30 of the refrigerating compartment duct 12 and the cold air inlet (30b) of the cold air inlet (30b) By connecting through the connection, the cold air flows into the upper door duct 30, the cold air introduced into the upper door duct 30 is discharged through the cold air outlet 30a, at the same time, the cold air distribution duct 34 A portion thereof flows into the lower door duct 32 and is discharged through the cold air discharge port 32a of the lower door duct 32.

따라서, 상술한 바와 같은 본 실시예에 따르면 상부 도어덕트(30) 및 하부 도어덕트(32)에 의해 냉기가 고르게 배출되어 냉기가 일측 방향으로 편중되지 않기 때문에 냉기가 집중되어 음식물이 과냉각되는 등의 현상이 발생하지 않게 된다.Therefore, according to the present embodiment as described above, since the cold air is evenly discharged by the upper door duct 30 and the lower door duct 32 and the cold air is not biased in one direction, the cold air is concentrated and the food is supercooled. The phenomenon does not occur.

본 발명에 따른 입체 냉각방식의 냉장고에 의하면 도어 측에서 배출되는 냉기가 소정의 거리를 두고 이격위치된 상 하부 도어덕트에 의해 분리 배출되기 때문에, 냉기가 일측으로 집중 배출되어 냉각공간 내의 온도편차가 심해짐으로써 특정 도어 바스켓에 수납된 음식물이 과냉되는 현상이 방지되는 등, 보다 안정적인 냉각작용이 가능하다는 이점이 있다.According to the three-dimensional cooling method of the refrigerator according to the present invention, since the cool air discharged from the door side is separated and discharged by the upper and lower door ducts spaced apart by a predetermined distance, the cool air is discharged to one side and the temperature deviation in the cooling space is increased. As it becomes more severe, there is an advantage that a more stable cooling action is possible, such as preventing the food stored in a specific door basket from being overcooled.
