본 발명은 냉장고의 냉기공급을 위한 구조에 관한 것으로, 더욱 상세하게는 냉동실의 냉기의 일부분을 도어측을 통하여 냉장실로 공급할 수 있도록 구성되는 냉기공급을 위한 구조에 관한 것이다.The present invention relates to a structure for supplying cold air of a refrigerator, and more particularly, to a structure for supplying cold air configured to supply a part of cold air of a freezer compartment to a refrigerating compartment through a door side.

냉장실의 냉기의 공급은 냉장실의 일측벽에 설치되어 있는 냉장실덕트를 통하여 공급된다. 냉장고의 증발기 부근에서 열교환된 냉기의 일부가 상기 냉장실덕트를 통하여 하방으로 내려와서, 냉장실덕트에 성형된 냉기토출공을 통하여 냉장실로 토출되는 것이다. 이러한 종래의 냉기공급구조에 의하면, 냉기가 냉장실의 일측면, 예를 들면 후면에서 전방을 향하는 일방향으로 냉기가 공급되기 때문에 냉장실 내부에서 전체적인 충분한 냉기의 공급이 문제가 되고 있다. 이러한 문제점을 해결하기 위하여 본 출원인은 냉장실 내부에서, 도어에서 냉장실 후방을 통하여 냉기를 공급할 수 있는 냉기공급구조를 제안한 바 있다.The supply of cold air in the refrigerating chamber is supplied through the refrigerating chamber duct provided on one wall of the refrigerating chamber. A portion of the cold air heat exchanged in the vicinity of the evaporator of the refrigerator descends through the refrigerating chamber duct and is discharged to the refrigerating chamber through the cold air discharge hole formed in the refrigerating chamber duct. According to such a conventional cold air supply structure, since cold air is supplied to one side of the refrigerating compartment, for example, in one direction from the rear to the front, supply of sufficient cold air as a whole becomes a problem. In order to solve this problem, the present applicant has proposed a cold air supply structure capable of supplying cold air from the door to the rear of the refrigerating chamber.

먼저 제1도 내지 제2도를 참조하면서 이러한 냉기공급구조에 대하여 살펴보기로 한다.First, this cold air supply structure will be described with reference to FIGS. 1 to 2.

도시한 바와 같이, 냉장실(2) 내부에 설치되어 있는 냉장실덕트(4)에 성형된 냉기토출공(4a)을 통하여 냉기가 냉장실(2)로 공급된다. 그리고 상기 냉장실덕트(4)에서 냉기안내덕트(6)가 분기되고, 상기 냉기안내덕트(6)는 도어(10)의 이면에 설치되어 있는 도어덕트(8)와 연결되어 있다. 따라서 냉장실덕트(4)로 공급되는 냉기의 일부분은, 상기 냉기안내덕트(6)를 통하여 도어덕트(8)에 공급된다. 상기 도어덕트(8)에 공급된 냉기는 도어덕트(8)의 냉기토출공(8a)를 통하여 냉기를 공급하게 된다. 이러한 구조에 의하면, 냉장실로 공급되는 냉기가 냉장실(2)의 후방 및 전방에서 입체적으로 공급되게 되는 것이다.As illustrated, cold air is supplied to the refrigerating chamber 2 through the cold air discharge holes 4a formed in the refrigerating chamber duct 4 provided in the refrigerating chamber 2. The cold air duct 6 is branched from the refrigerating chamber duct 4, and the cold air duct 6 is connected to the door duct 8 provided on the rear surface of the door 10. Therefore, a part of the cold air supplied to the refrigerating chamber duct 4 is supplied to the door duct 8 through the cold air guide duct 6. The cold air supplied to the door duct 8 supplies cold air through the cold air discharge holes 8a of the door duct 8. According to this structure, the cold air supplied to the refrigerating compartment is supplied in three dimensions at the rear and front of the refrigerating compartment 2.

상기와 같은 구성에 의하여 냉장실(2)의 내부에서는 전방 및 후방에서 입체적으로 냉기가 공급되지만, 상술한 구조에 의하면 다음과 같은 단점이 지적된다.By the above configuration, the cold air is supplied three-dimensionally in the front and rear of the refrigerating chamber 2, but the following disadvantages are pointed out according to the above-described structure.

냉장실덕트(4)에서 분기되어 도어(9) 측을 향하여 연장되는 냉기안내 덕트는, 냉장실 내부의 측벽에 설치되어 있기 때문에 실질적으로 냉장실의 공간의 일부를 차지하게 되어 냉장실의 공간사용 효율이 저하되는 단점이 있다.Since the cold air guide duct branched from the refrigerating chamber duct 4 and extending toward the door 9 side is provided on the side wall of the refrigerating chamber, the cold air duct substantially occupies a part of the space of the refrigerating chamber, thereby reducing the space usage efficiency of the refrigerating chamber. There are disadvantages.

그리고 냉장실덕트(4)에서 분기되어, 도어(9)에 설치되어 있는 도어덕트(8)에 연결하는 냉기안내덕트(6)의 길이가 길고, 각각에 연결하기 위한 연구구조에 의하여 도어덕트(8)에 이르는 동안 냉기의 손실이 발생한다. 따라서 실질적으로 도어덕트(8)를 통하여 냉장실의 후방을 향하여 공급되는 냉기가 충분하지 않게 되는 단점이 있는 것이다.The length of the cold air duct duct 6 branched from the refrigerating chamber duct 4 and connected to the door duct 8 installed in the door 9 is long, and the door duct 8 has a research structure for connecting to the door duct 8. Loss of cold occurs. Therefore, there is a disadvantage in that the cold air supplied toward the rear of the refrigerating compartment through the door duct 8 is not sufficient.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 도어덕트로의 충분한 냉기를 공급할 수 있는 냉기공급구조를 제공하는 것을 목적으로 하고 있다.The present invention has been made to solve such a problem, and an object of the present invention is to provide a cold air supply structure capable of supplying sufficient cold air to a door duct.

본 발명의 다른 목적은 냉장실의 사용공간을 충분히 확보하면서도, 도어덕트로 냉기를 안내할 수 있는 냉기공급구조를 제공하는 것이다.Another object of the present invention is to provide a cold air supply structure that can guide the cold air to the door duct while ensuring sufficient use space of the refrigerating compartment.

상기 목적을 달성하기 위한 본 발명에 의한 냉기공급구조는, 냉동실 도어에 설치되어 냉동실의 냉기의 일부를 하방으로 안내하는 냉동실도어덕트와, 냉장실도어에 설치되고, 상기 냉동실도어덕트에서의 냉기를 공급받아 도어에서 후방을 향하여 냉장실로 공급하는 냉장실도어덕트, 그리고 상기 냉동실도어덕트와 냉장실도어덕트를 연통하도록 연결하는 연통수단을 포함하여 구성된다. 이러한 구성에 의하여, 냉동실의 도어의 일부가 냉동실도어 및 냉장실도어를 통하여 냉장실로 공급되는 것이다.The cold air supply structure according to the present invention for achieving the above object is provided in the freezer compartment door to guide a part of the cold air of the freezer compartment downward, and is installed in the refrigerating compartment door, to supply the cold air in the freezer compartment duct And a refrigerating compartment door duct receiving the door from the door to the refrigerating compartment, and communicating means for connecting the freezer compartment duct to the refrigerating compartment door duct. By this configuration, a part of the door of the freezer compartment is supplied to the refrigerating compartment through the freezer compartment door and the refrigerating compartment door.

그리고 상기 연통수단에 대한 일실시예에 의하면, 냉동실도어와 냉장실도어를 회동 가능하게 지지하는 힌지와, 상기 힌지의 내부에 설치되는 힌지덕트로 구성되어, 상기 냉동실도어덕트와 냉장실도어덕트는 힌지덕트에 의하여 연통하게 되어, 외관상 추가되는 구성없이 냉동실의 냉기를 냉장실로 공급할 수 있게 된다.And according to one embodiment of the communication means, the freezing chamber door and the refrigerating chamber door hinge and rotatably configured, the hinge duct is provided inside the hinge, the freezer door duct and the cold room door duct is a hinge duct By communicating with each other, it is possible to supply the cold air of the freezer compartment to the refrigerating compartment without any configuration added in appearance.

냉장실도어덕트에서 냉기를 분출하는 출구를, 냉장실도어의 이면에 설치되는 도어바스켓과 인접한 위치에 설치함으로써, 냉장실의 도어바스켓에 보관중인 식품을 더욱 신선한 상태로 유지하는 것이 가능하게 된다.By installing an outlet for ejecting cold air from the refrigerating compartment door duct at a position adjacent to the door basket provided on the rear side of the refrigerating compartment door, it is possible to keep food stored in the door basket of the refrigerating compartment in a fresher state.

다음에는 도시된 실시예에 기초하면서 본 발명에 대하여 더욱 상세하게 설명하기로 한다.Next, the present invention will be described in more detail with reference to the illustrated embodiment.

본 발명은, 냉동실의 온도는 냉장실의 온도에 비하여 훨씬 저온의 상태를 유지하고 있다는 점에 감안하여, 냉동실의 냉기의 일부를, 냉장실에 설치된 도어덕트를 통하여 냉장실로 안내하여, 그 냉기를 냉장실 후방으로 공급되도록 구성하는 것을 특징으로 하고 있다.In view of the fact that the temperature of the freezer compartment is maintained at a much lower temperature than the temperature of the refrigerator compartment, a part of the cold air of the freezer compartment is guided to the refrigerator compartment through a door duct installed in the refrigerator compartment, and the cold air is rearward of the refrigerator compartment. It is characterized in that the configuration to be supplied.

제3도를 참조하면서 본 발명에 의한 구성을 보다 상세하게 설명한다. 도시한 바와 같이, 냉동실도어(11)의 내부에는 냉동실도어덕트(12)가 설치되어 있다. 상기 냉동실도어덕트(12)는, 냉동실 도어(11)의 이면의 일측에 입구(12a)가 성형되고, 도어(11)의 하단부까지 연통되어 그 하단부에 출구(12b)를 구비하고 있다. 따라서 냉동실(10)의 냉기의 일부가 상기 냉동실도어덕트(12)를 통하여 유입되어 도어(11)의 하단으로 안내될 수 있는 것이다.With reference to FIG. 3, the structure by this invention is demonstrated in detail.

그리고 냉장실(20)의 도어(21)에는 상기 냉동실도어덕트(12)에서의 냉기를 공급받을 수 있는 냉장실도어덕트(22)가 설치되어 있다. 상기 냉동실도어덕트(12)는, 냉동실도어덕트(12)의 출구(12b)에서의 냉기를 공급받을 수 있도록 냉장실도어(21)의 상면에 성형된 입구(22a)와, 상기 입구(22a)와 연통하며, 냉장실도어(21)의 이면에 성형된 출구(22b)를 구비한다. 따라서 상기 냉장실도어덕트(22)의 내부로 공급된 냉기는, 냉장실도어(21)에서 후방을 향한 냉기를 냉장실(20)로 공급하게 되는 것이다.And the door 21 of the refrigerating chamber 20 is provided with a refrigerating chamber door duct 22 that can receive the cool air from the freezer compartment duct 12. The freezer compartment duct 12 includes an inlet 22a formed on the upper surface of the refrigerating compartment door 21 to receive cold air from the outlet 12b of the freezer compartment duct 12, and the inlet 22a and the inlet 22a. The outlet 22b is formed in communication with the rear surface of the refrigerating chamber door 21. Therefore, the cold air supplied into the refrigerating chamber door duct 22 is to supply the cold air toward the rear side from the refrigerating chamber door 21 to the refrigerating chamber 20.

그리고 냉장실도어덕트(22)의 출구(22b)는 냉장실도어(21)의 이면에 성형되어, 공급되는 냉기를 냉장실(20)의 후방으로 공급하기 위한 것이고, 냉장실도어(21)의 이면에는 음식물을 보관하기 위한 복수개의 도어바스켓(26)이 설치되어 있다. 따라서 상기 냉장실도어덕트(22)의 출구(22b)를 통하여 내부로 분사되는 냉기가, 상기 도어바스켓(26)에 보관중인 식품을 거쳐서 내부로 안내될 수 있도록 하면, 도어바스켓(26)의 보관 식품에 직접 냉기가 공급되도록 함으로써, 빈번한 도어의 개폐에 의하여 고온으로 되기쉬운 도어바스켓(26)에 보관중인 식품을 특히 신선하게 보관하는 것이 가능하게 된다.The outlet 22b of the refrigerating chamber door duct 22 is formed on the rear surface of the refrigerating chamber door 21 to supply the supplied cold air to the rear of the refrigerating chamber 20, and food is provided on the rear surface of the refrigerating chamber door 21.

이렇게 하여 냉장실도어덕트(22)로 유입된 냉기는 하강하면서, 그 출구(22b)를 통하여 냉장실(10)로 공급된다. 상기 냉장실도어덕트(22)를 통하여 냉장실(20)로 공급되는 냉기는 실질적으로 냉장실에서 후방을 향하는 냉기의 흐름을 형성하게 된다. 따라서 본 발명에 의하면, 냉장실(20)에는 전방 및 후방을 향하는 냉기에 의하여 입체적 냉각이 가능하게 되어, 전체적으로 균일한 냉장효과를 얻을 수 있게 된다. 또한 상기 냉장실도어덕트(22)의 출구(22b)를 도어바스켓(26)과 인접한 부분에 성형하는 것에 의하여, 공급되는 냉기가 도어바스켓(26)에 보관중인 식품을 거치기 때문에, 특히 도어바스켓(26)에 보관중인 식품을 신선하게 보관할 수 있게 되는 것이다.In this way, cold air which flowed into the refrigerator compartment door duct 22 descend | falls, and is supplied to the refrigerator compartment 10 via the outlet 22b. The cold air supplied to the refrigerating chamber 20 through the refrigerating chamber door duct 22 substantially forms a flow of cold air toward the rear of the refrigerating chamber. Therefore, according to the present invention, three-dimensional cooling is possible in the refrigerating chamber 20 by the cold air toward the front and the rear, and the overall refrigeration effect can be obtained. In addition, by forming the outlet 22b of the refrigerating chamber door duct 22 in a portion adjacent to the door basket 26, since the supplied cold air passes through the food being stored in the door basket 26, the door basket 26 ) Will keep the food in storage fresh.

그리고 본 발명에 의하여 냉동실도어덕트(12)를 통하여 냉장실(20)로 유입되는 냉기는 실질적으로 냉동실(10)에서 유입되는 것이기 때문에, 충분한 저온 상태의 것으로, 충분한 냉장효과가 기대된다.In addition, since the cold air flowing into the refrigerating chamber 20 through the freezer compartment duct 12 is substantially introduced into the freezing chamber 10, the present invention is sufficiently low in temperature, and a sufficient refrigerating effect is expected.

이상과 같이 구성되는 본 발명에 의하면, 실질적으로 냉장실의 내부에서 전방 및 후방에서 각각 냉기를 공급하기 때문에 전체적으로 균일한 냉장효과를 얻을 수 있다. 또한 도어의 빈번한 개폐에 의하여 온도가 상승하기 쉬운 도어의 전방부분, 특히 도어바스켓 부분에 대한 냉기의 공급이 충분하기 때문에, 이러한 부분에 대한 충분한 냉장효과를 유지할 수 있게 된다.According to the present invention configured as described above, since refrigeration air is supplied from the front and the rear of the inside of the refrigerating chamber, respectively, the overall uniform refrigeration effect can be obtained. In addition, since the supply of cold air to the front part of the door, particularly the door basket part, which is likely to increase in temperature due to frequent opening and closing of the door, sufficient refrigeration effect for such a part can be maintained.

그리고 상술한 바와 같은 구성에 의하면, 냉장실의 도어덕트(22)로 냉기를 안내하기 위한 별도의 덕트를 냉장실 내부에 설치하고 있지 않기 때문에, 냉장실의 사용공간을 더욱 넓힐 수 있는 잇점도 기대된다.According to the above-described configuration, since no additional duct for guiding the cold air to the door duct 22 of the refrigerating compartment is provided inside the refrigerating compartment, an advantage of further increasing the use space of the refrigerating compartment is also expected.
