Description

냉장고의 냉기 공급구조Cold air supply structure of the refrigerator

본 발명은 냉장고의 냉기공급구조에 관한 것으로, 더욱 상세하게는 냉기가 냉장실로 공급되는 냉장실유로에서 도어측으로 별도의 분기유로를 형성하고, 냉장실과 도어측의 온도 비교에 의해 도어측으로 냉기가 공급되어 적정냉각을 이루기 위한 냉기공급구조에 관한 것이다.The present invention relates to a cold air supply structure of a refrigerator, and more particularly, to form a separate branch flow path from the refrigerating chamber flow path where cold air is supplied to the refrigerating compartment to the door side, and to supply the cold air to the door side by comparing the temperature between the refrigerating compartment and the door side. The present invention relates to a cold air supply structure for achieving proper cooling.

먼저 제1도 및 제2도를 참조하면서 종래의 냉장고의 구조 및 냉기공급을 위한 구조에 대하여 살펴보기로 한다.First, referring to FIGS. 1 and 2, a structure of a conventional refrigerator and a structure for supplying cold air will be described.

도시된 바와 같이, 냉장고의 내부는, 단열재가 충진된 베리어(2)에 의하여 냉동실(1)과 냉장실(3)로 나누어져 있다. 냉기의 공급구조를 살펴보면, 저온 저압의 냉매가 내부를 통과하는 증발기(1a)에서 열교환된 냉기의 일부는, 송풍팬(1b)에 의하여 쉬라우드(1c)를 거쳐 냉동실(1)로 공급되고, 나머지 일부는 상기 쉬라우드(1c)를 거쳐 자유 낙하하여 냉장실(3)로 공급된다. 냉장실(2)로의 냉기의 공급은, 냉장실(3) 후방에 길이 방향으로 설치되어 있는 냉장실덕트(4)를 통하여 자유낙하하면서, 상기 냉장실덕트(4)의 전면에 형성되어 있는 다수개의 냉기토출구(4a)를 통하여 냉장고의 후방에서 전방을 향하여 냉기가 토출되도록 구성되어 있다.As shown, the inside of the refrigerator is divided into a freezer compartment 1 and a refrigerating compartment 3 by a barrier 2 filled with insulation. Looking at the supply structure of the cold air, a part of the cold air heat exchanged in the evaporator (1a) through which the low-temperature low-pressure refrigerant passes through the inside, is supplied to the freezing chamber (1) through the shroud (1c) by the blowing fan (1b), The remaining part is free-falled through the shroud 1c and supplied to the refrigerating chamber 3. The supply of cold air to the refrigerating chamber 2 is freely dropped through the refrigerating chamber duct 4 provided in the longitudinal direction at the rear of the refrigerating chamber 3, and a plurality of cold air discharge ports formed on the front surface of the refrigerating chamber duct 4 ( The cold air is discharged from the rear of the refrigerator toward the front through 4a).

이와 같은 과정을 통하여 냉동실(1) 및 냉장실(3)로 공급된 냉기는 내부에 보관중인 식품과의 열교환 과정을 거쳐 상대적으로 고온으로 되고, 고온으로 된 공기는 베리어(2)의 내부에 성형된 환덕트(2a)를 통하여 다시 증발기(1a) 부근으로 이동하게 된다.The cold air supplied to the freezer compartment 1 and the refrigerating compartment 3 through this process becomes relatively high temperature through heat exchange with the food stored therein, and the air having a high temperature is formed inside the barrier 2. It moves to the vicinity of the evaporator 1a through the ring duct 2a.

그리고 상기 냉동실(1)과 냉장실(3)은 각각 도어(5)에 의하여 개폐될 수 있도록 되어 있고, 냉장실도어(5)의 내측에는 음식들을 보관하기 위한 도어바스켓(5a)이 다단으로 설치되어 있다.The freezer compartment 1 and the refrigerating compartment 3 are each opened and closed by a door 5, and a door basket 5a for storing foods is provided in multiple stages inside the refrigerating compartment door 5. .

이와 같은 냉기공급구조에 있어서, 냉동실(1)은 통상 그 체적이 작기 때문에 심각한 문제로 대두되지 않지만, 특히 냉장실(3)은 냉기의 전체적인 순환이 문제가 된다. 즉 상술한 바와 같이, 냉기가 후방에서 전방으로의 일방향으로만 공급되고 있기 때문에 전체적으로 균일한 냉장효과를 달성하기 못하는 문제점이 지적되는 것이다.In such a cold air supply structure, the freezer compartment 1 is usually not a serious problem because of its small volume, but in particular, the overall circulation of cold air is a problem for the refrigerator compartment 3. That is, as described above, since the cold air is supplied only in one direction from the rear to the front, it is pointed out that the overall refrigeration effect cannot be achieved.

따라서 냉기의 공급원과 가장 이격된 위치인 도어(5)측에는 충분하게 냉기가 공급되지 못하기 때문에, 냉기토출공(4a)와 인접하게 놓인 음식물은 과냉되고, 도어(5)측에 위치한 음식물은 충분한 냉장효과를 달성하지 못하고 있다. 이리한 문제점은 냉장실(3) 내부의 냉기공급이 후방에서 전방을 향하는 일방향으로 공급되고 있다는 점에 기인하고 있다.Therefore, since the cold air is not sufficiently supplied to the side of the door 5, which is the position most separated from the source of cold air, the food placed adjacent to the cold air discharge hole 4a is supercooled, and the food located on the side of the door 5 is sufficient. The refrigeration effect is not achieved. This problem is due to the fact that the cold air supply inside the refrigerating chamber 3 is supplied in one direction from the rear to the front.

또한 도어바스켓(5a)이 설치되어 있는 도어(5) 부근에는, 도어(5)의 빈번한 개폐에 따른 외부 공기의 유입으로 인하여 냉장실(3)의 내측에 비하여 현저하게 높은 온도를 유지하는 경향이 많다. 따라서 냉장고 도어(5)의 바스켓(5a)에 보관하는 식품은 특히 신선도 유지가 어렵게 되는 단점이 있는 것이다.In addition, in the vicinity of the door 5 where the door basket 5a is installed, there is a tendency to maintain a significantly higher temperature than the inside of the refrigerating chamber 3 due to the inflow of external air due to frequent opening and closing of the door 5. . Therefore, the food stored in the basket 5a of the refrigerator door 5 has a disadvantage in that it is particularly difficult to maintain freshness.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 냉장실에서 전체적으로 균일한 냉장효과를 얻을 수 있는 냉기공급구조를 제공하는 것을 목적으로 한다.The present invention is to solve the above problems, and an object of the present invention is to provide a cold air supply structure that can obtain a uniform refrigeration effect as a whole in the refrigerating chamber.

본 발명의 다른 목적은 특히 냉장실의 도어측에 냉기를 충분하게 공급할 수 있는 냉기공급구조를 제공하는 것이다.Another object of the present invention is to provide a cold air supply structure capable of supplying a sufficient amount of cold air, especially to the door side of the refrigerating chamber.

본 발명의 또 다른 목적은 외기의 유입으로 온도가 상승하는 냉장실의 전방 부분을 신속하게 냉각시킬 수 있는 냉기공급구조를 제공하는 것이다.Still another object of the present invention is to provide a cold air supply structure capable of rapidly cooling the front portion of the refrigerating compartment, in which temperature increases due to inflow of outside air.

그리고 상기 냉기전달수단은, 도어유로의 입구에 형성되는 송풍팬으로 구성되도록 할 수 있다. 또한, 도어측 내부의 온도를 감지하는 온도감지센서가 일측에 위치하고, 상기 송풍팬은 감지된 온도에 의해 구동되도록 할 수가 있다.The cold air transfer means may be configured of a blowing fan formed at the inlet of the door flow path. In addition, a temperature sensor for sensing the temperature inside the door side is located on one side, the blowing fan may be driven by the sensed temperature.

이하에서는 도면에 도시된 실시예를 참조하면서 본 발명을 더욱 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

본 발명의 냉기공급구조를 도시하고 있는 제2도 내지 제5도에 도시한 바와 같이, 본 발명에 의하면 냉동실(10) 후방의 증발기(12)에서 열교환된 냉기를 냉장실(60)로 냉기를 공급하기 위해 베리어(20) 내에 위치한 베리어덕트(30)의 일측에서 도어(80)전방측으로 향하는 분기유로(40)를 설치하여, 상기 분기유로(40)를 통하는 냉기를 도어(80) 측에 공급하도록 구성하는 것을 특징으로 하고 있다.As shown in FIGS. 2 to 5 showing the cold air supply structure of the present invention, the cold air heat-exchanged in the evaporator 12 behind the freezer compartment 10 is supplied to the cold compartment 60 according to the present invention. In order to install a branch passage 40 toward the front side of the door 80 from one side of the barrier duct 30 located in the barrier 20, to supply the cool air through the branch passage 40 to the door 80 side It is characterized by the configuration.

본 발명의 냉기공급구조에 대하여, 냉기의 생성에서 공급까지의 과정을 통하여 설명하기로 한다. 내부에서 냉매가 기화하는 증발기(12)의 부근에서 열교환된 냉기의 일부는 송풍팬(14)에 의하여 냉등실(10)로 공급되고, 다른 일부는 낙하하여 베리어덕트(30)를 지나 냉장실(60) 후방에 위치한 냉장실덕트(50)를 통하여 냉장실(40)로 공급된다.The cold air supply structure of the present invention will be described through a process from generation of cold air to supply. A part of the cold air heat-exchanged in the vicinity of the evaporator 12 in which the refrigerant vaporizes is supplied to the cooling chamber 10 by the blower fan 14, and the other part is dropped and passes through the barrier duct 30 to the refrigerating chamber 60. It is supplied to the refrigerating chamber 40 through the refrigerating chamber duct 50 located in the rear.

상기 베리어(20) 내부에 위치한 베리어덕트(30)의 일측에서는, 분기유로(40)가 분기되어 냉기의 일부를 도어(80)측으로 안내할 수 있게 되어 있다. 상기 분기유로(40)는, 베리어(20)의 내부에서 분기되거나 냉장실덕트(50)의 최상단 부분에서 분기되어 베리어(20)내부를 지나 도어(80)측으로 안내될 수가 있다. 도시된 실시예에서는 베리어(20) 내부에 위치하는 베리어덕트(30)의 일측에서 분기되어 베리어(20) 내부를 가로질러 냉장실(60)의 전방으로 유도된 후, 냉장실(60) 측벽(62)을 따라 수직하방으로 유도되어 냉장실(60)의 측벽(62) 단부에 그 출구(42)가 형성되는 구조로 이루어져 있다.At one side of the barrier duct 30 located inside the barrier 20, the branch passage 40 is branched to guide a part of the cold air to the door 80 side. The branch passage 40 may be branched inside the barrier 20 or branched from the uppermost portion of the refrigerating chamber duct 50 to pass through the barrier 20 to the door 80. In the illustrated embodiment, after branching from one side of the barrier duct 30 located inside the barrier 20 to guide the front of the refrigerator compartment 60 across the barrier 20, the side wall 62 of the refrigerator compartment 60 is formed. In the vertical direction is guided along the end of the side wall 62 of the refrigerating chamber 60 is formed of a structure that is formed.

그리고, 상기 분기유로(40)에서의 냉기는 도여(80)의 내부에 설치되어 있는도어유로(90)으로 안내된다. 상기 도어유로(90)의 입구(92)는, 도어(80)가 닫힌 상태에서 냉장실 측벽(62)의 전방 단부에 설치되어 있는 분기유로(40)의 출구(42)와 서로 밀착될 수 있는 위치에 성형되어 있어서, 도어(80)가 닫히면 상기 분기유로(40)에서의 냉기가 도어유로(90)의 내부에 공급되개 된다. 상기 분기유로(40)가 냉장실 측벽(62)에 설치되어, 측벽(62)의 전방에서 냉기를 토출하는 구조를 가지고 있기 때문에, 상기 도어유로(90)의 입구(92)는 도어(80)와 측면에 성형되어야 한다.The cold air in the branch passage 40 is guided to the door passage 90 which is installed inside the donor 80. The inlet 92 of the door passage 90 may be in close contact with the outlet 42 of the branch passage 40 installed at the front end of the side wall 62 of the refrigerating compartment in a state where the door 80 is closed. And the door 80 is closed, the cold air in the branch flow path 40 is supplied to the interior of the door flow path (90). Since the branch passage 40 is provided on the side wall 62 of the refrigerating chamber and has a structure for discharging cold air in front of the side wall 62, the inlet 92 of the door passage 90 is connected to the door 80. It must be molded on the side.

한편, 도 5에 도시된 바와 같이, 본 실시예에서는 상기 도어유로(90)의 입구(92)에는 도어(80)측으로 냉기를 강제로 전달할 수 있도록 냉기전달수단이 설치된다. 상기 냉기전달수단은 송풍팬(100)으로 이루어지며, 상기 송풍팬(100)의 구동에의해 분기유로(40)를 통한 냉기가 강제로 도어유로(90)측으로 전달되어 도어(80)측에서 원활한 냉기공급이 이루어진다.On the other hand, as shown in Figure 5, in the present embodiment, the inlet 92 of the door flow path 90 is provided with cold air transfer means to forcibly transfer the cold air to the door 80 side. The cold air delivery means is composed of a blowing fan 100, by the driving of the blowing fan 100, cold air through the branch flow path 40 is forcibly delivered to the door flow path (90) side and smooth on the door 80 side Cold air supply is made.

그리고, 상기 송풍팬(100)의 구동은 도어(80)측에서 감지된 온도에 따라 구동된다. 즉, 도어(80)측에는 도어부의 온도를 감지하기 위한 온도감지센서(82)가 위치하고 있고, 상기 온도감지센서(82)에 의해 감지된 온도가 일정온도 이상이면 송풍팬(100)의 구동이 이루어 지도록 하여 냉기를 강제로 도어(80)측으로 유도되도록 한다. 도어(80)측에 위치한 온도감지센서(82)는 도어(80)측과 또한 냉장실(60)전방부분의 온도를 주로 감지하게 될 것이고, 상기 온도감지센서(82)는 냉장실(60) 내부의 온도감지센서(60a)와는 별개로 작동되어 도어(80)측의 온도에 의해 송풍팬(100)은 구동되게 되는 것이다.In addition, the driving of the blowing fan 100 is driven according to the temperature sensed by the door 80 side. That is, the temperature sensor 82 for detecting the temperature of the door portion is located on the door 80 side, and if the temperature detected by the temperature sensor 82 is above a predetermined temperature, the driving of the blower fan 100 is made. The cold air is forcibly directed to the door 80 side. The temperature sensor 82 located on the door 80 side will mainly detect the temperature of the door 80 side and the front part of the refrigerating chamber 60, and the temperature sensor 82 is located inside the refrigerating chamber 60. The blower fan 100 is driven by the temperature of the door 80 side separately from the temperature sensor 60a.

도어(80)측 온도감지센서(82)와 냉장실 내부 온도감지센서(60a)와의 차이점을 설명하면, 도 3에 도시된 바와 같이, 냉장실(60)내벽 양측에는 온도감지센서(60a)가 설치되어 있으며, 상기 온도감지센서(60a)는 냉장실(60)내부의 온도를 감지하고, 상기 감지된 온도에 따라 냉기차단막(60a)는 냉장실(60) 내부로 냉기의 공급이 조절된다. 그러나, 도어측 온도감지센서(82)는 냉기차단막의 개폐와는 상관없이 도어(80)측에서 감지된 온도에 따라 단지 송풍팬(100)의 구동만 이루어지고, 상기 송풍팬(100)의 구동에 의해 냉기가 도어(80)측으로 강제 유입되도록 한다.Referring to the difference between the temperature sensor 82 of the door 80 side and the temperature sensor 60a inside the refrigerating compartment, as shown in FIG. 3, the temperature sensor 60a is installed on both sides of the inner wall of the refrigerating compartment 60. The temperature sensor 60a detects a temperature inside the refrigerating chamber 60, and the cold air blocking film 60a controls the supply of cold air into the refrigerating chamber 60 according to the sensed temperature. However, the door-side temperature sensor 82 is driven only by the blowing fan 100 according to the temperature sensed by the door 80 regardless of opening and closing of the cold air blocking membrane, and driving of the blowing fan 100. By the cold air is forced to flow into the door (80) side.

상기와 같이 냉기가 강제유입됨으로서 냉장실(60) 내부 후방에 위치한 냉기 토출공(52)으로부터 이격된 도어(80)측에서도 충분한 냉기의 공급이 이루어져 도어(80)측에 보관된 식품을 신선한게 유지할 수 있게 된다.As the cold air is forcedly introduced as described above, sufficient cold air is supplied even from the side of the door 80 spaced apart from the cold air discharge hole 52 located inside the refrigerating chamber 60 to keep the food stored in the door 80 fresh. Will be.

한편, 본 실시예에서는 상기 송풍팬(100)이 도어유로(90)의 입구(92)에 위치하고 있으나, 이에 국한되는 것은 아니다. 즉, 상기 송풍팬(100)은, 냉기를 도어(80)측으로 강제유입 시킬 수 있는 위치라면 어디라도 족한 것이다. 본 실시예와는 달리 분기유로(40)의 일측에 설치되는 것도 무방하며, 또한 베리어덕트(30)에서 분기유로(40)가 분기되는 위치에 설치되어도 무방하다.On the other hand, in the present embodiment, the blowing fan 100 is located at the inlet 92 of the door flow path 90, but is not limited thereto. That is, the blower fan 100 is sufficient in any position where the cold air can be forced to the door 80 side. Unlike the present embodiment, it may be installed on one side of the branch passage 40, and may also be installed at a position where the branch passage 40 is branched from the barrier duct 30.

그리고 상기 도어유로(90)는, 도어유로(90)의 입구(92)에서 수평방향으로 연장되어 있는 수평부분을 포함하여, 공급되는 냉기가 수평부분로 공급될 수 있도록 연통되어 있다. 상기 수평부분은, 도어(80)의 내측에서 음식물을 적재하는 도어바스켓(84)를 따라 성형되는 것이 바람직하다. 그리고 상기 도어유로(90)에는 냉기를토출하기 위한 냉기토출공(94)이 복수개 성형되어 있다. 이리한 냉기토출공(94)은, 도어(80)측에서 냉장고의 후방을 향하여 냉기가 분출될 수 있도록 성형되는 것도 가능하고, 도어유로(90)의 수평부분이 도어바스켓(94)에 성형되는 점을 고려하여, 도어바스켓(94)에 보관중인 식품을 향하여 직접 냉기를 공급할 수 있도록 성형하는 것도 가능하다. 또한 상기 도어유로(90)의 냉기토출공(94)의 일부는 냉장실 내부를 향하여, 그리고 다른 일부는 도어바스켓(84)에 보관중인 식품을 향하여 냉기를 공급할 수 있는 방향에 성형하는 것도 가능할 것이다.The door passage 90 includes a horizontal portion extending in the horizontal direction from the inlet 92 of the door passage 90 so as to communicate with the supplied cold air to the horizontal portion. The horizontal portion is preferably molded along the door basket 84 for loading food inside the door 80. A plurality of cold air discharge holes 94 for discharging cold air are formed in the door flow path 90. The cold air discharge hole 94 may be formed such that cold air may be ejected toward the rear of the refrigerator from the door 80 side, and the horizontal portion of the door flow path 90 may be formed in the door basket 94. In consideration of the point, it is also possible to mold so that the cold air can be supplied directly toward the food being stored in the door basket 94. In addition, a part of the cold air discharge hole 94 of the door flow path 90 may be molded in a direction in which cold air may be supplied toward the inside of the refrigerating chamber, and the other part toward the food stored in the door basket 84.

그리고 도시된 실시예에 있어서, 상기 수평부분은, 하나의 도어바스켓(34)에 설치되어 있는 예를 통하여 설명되고 있으나, 상기 수평부분은 복수개의 도어바스켓(84)에 전부 설치하는 것이 가능함은 당연한 것이다.In the illustrated embodiment, the horizontal portion is described through an example in which one door basket 34 is installed, but it is obvious that the horizontal portion may be installed in a plurality of door baskets 84. will be.

다음에는 이상과 같이 구성되는 본 고안에 의한 냉장고의 전체적인 냉기의 흐름을 살펴보기로 한다.Next, look at the flow of the cold air of the refrigerator according to the present invention configured as described above.

냉장고가 구동되어 냉장실(60) 내부의 온도감지센서(60a)에 의해 감지된 온도가 일정온도 이상이 되어 냉기차단막의 개방에 따라 냉기가 공급되기 시작하면, 증발기(12)에서 열교환된 냉기는 베리어덕트(20)를 지나 냉장실덕트(50)를 통해 냉장실(60)로 냉기를 공급하기 위해 냉기가 낙하하기 시작한 것이다. 그리고 이때 베리어덕트(30)에서 분기된 분기유로(40)로 냉기가 공급되고, 이러한 냉기는 분기유로(40)를 따라 냉장실측벽(62)을 따라 냉장실(60) 전방으로 안내되어, 냉장실측 벽(62)에 성형된 출구(42)로 나오게 된다. 이 때 도어(80)의 측면에 성형된 도어유로(90)의 입구(92)는 상기 출구(42)와 대응하는 위치에 성형되어 있기 때문에, 분기유로(40)에서 공급되는 냉기는 도어유로(90)에 공급되게 된다.When the refrigerator is driven and the temperature sensed by the temperature sensor 60a in the refrigerating chamber 60 becomes a predetermined temperature or more and cold air starts to be supplied as the cold air barrier is opened, the cold heat exchanged in the evaporator 12 is a barrier. In order to supply cold air to the refrigerating chamber 60 through the refrigerating chamber duct 50 through the duct 20, cold air starts to fall. At this time, cold air is supplied to the branch passage 40 branched from the barrier duct 30, and the cold air is guided forward along the refrigerating chamber side wall 62 along the branch passage 40 to the front of the refrigerating chamber 60. It exits to the outlet 42 shaped at 62. At this time, since the inlet 92 of the door flow path 90 formed on the side of the door 80 is formed at a position corresponding to the outlet 42, the cold air supplied from the branch flow path 40 is a door flow path ( 90).

도어유로(90)에 들어온 냉기는 수평부분을 따라 공급되며, 이 때 상기 수평부분에 선택적으로 성형된 냉기토출공(94)을 통하여 도어(80)측의 내부로 냉기가 공급되게 된다.The cold air entering the door flow path 90 is supplied along the horizontal portion, and at this time, the cold air is supplied to the inside of the door 80 through the cold air discharge hole 94 selectively formed in the horizontal portion.

한편, 냉장실(60) 내부에서 감지된 온도가 일정온도 이하가 되어 냉기공급이 필요없으면, 냉기차단막이 개폐되어 냉장실(60) 내부로 냉기공급이 중단된다. 그러나 이경우에도 냉장실덕트(50)의 입구에 위치한 냉기차단막에 의해 냉기가 냉장실로 전달될 수 없을 뿐이지 베리어덕트(30)내에는 일정양의 냉기가 잔존하게 된다.On the other hand, if the temperature sensed inside the refrigerating chamber 60 is below a predetermined temperature, and the cold air supply is not necessary, the cold air blocking membrane is opened and closed to stop the cold air supply into the refrigerating chamber 60. However, even in this case, only the cold air cannot be delivered to the refrigerating chamber by the cold air blocking membrane located at the inlet of the refrigerating chamber duct 50, but a certain amount of cold air remains in the barrier duct 30.

사용자가 도어(80)를 열고 도어(80)측에 새로운 부하의 투입으로 인하여 도어(80)측의 온도가 상승하게 되면, 도어측의 온도감지센서(82)가 감지한 온도가 일정온도 이상이 되고, 이에 따라 냉장실(60)로의 냉기공급과 상관없이 송풍팬(100)이 구동되어 베리어덕트(30)내의 냉기가 도어(80)측으로 공급되어 도어측에 위치한 부하를 냉각시키게 된다. 또한 상기의 경우와는 달리 수시로 도어(80)를 개폐함에 따라 도어측의 온도가 상승하였을 때도 마찬가지로 송풍팬(100)의 구동에 의해 도어측으로 냉기가 공급될 것이다. 즉, 종래에는 도어측의 온도감지가 곤란하여 도어측에 보관된 식품이 충분히 냉각되지 않았으나, 본 발명에서는 도어측의 온도감지에 의해 냉장실로의 냉기공급과 상관없이 도어측으로 냉기가 공급될 수 있으므로 도어측에 보관된 식품의 신선도가 충분히 유지될 수가 있게 된다.When the user opens the door 80 and the temperature of the door 80 rises due to the input of a new load on the door 80 side, the temperature detected by the temperature sensor 82 on the door side exceeds a predetermined temperature. Accordingly, regardless of the supply of cold air to the refrigerating chamber 60, the blower fan 100 is driven to supply cool air in the barrier duct 30 to the door 80 to cool the load located at the door side. In addition, unlike the above case, as the door 80 is frequently opened and closed, cold air will be supplied to the door side by driving the blower fan 100 when the temperature of the door side is increased. That is, in the prior art, it is difficult to detect the temperature on the door side, but the food stored on the door side has not been sufficiently cooled. However, in the present invention, the cold air may be supplied to the door side regardless of the cold air supply to the refrigerating chamber by the temperature detection on the door side. The freshness of the food stored on the door side can be maintained sufficiently.

이상과 같은 본 고안에 의하면, 냉장실로 공급되는 냉기가, 종래의 냉기공급구조에 의하여 후방에서 전방으로 냉기가 공급되는 것과 동시에, 냉동실 도어측에서도 냉기가 공급되고, 따라서 냉장실의 전후방에서 입체적으로 서로 냉기를 분출하고 있어서, 냉장실 전체의 온도가 균일하게 유지될 수 있기 때문에, 냉장실 전체적으로 균일한 냉장효과를 얻을 수 있게 된다.According to the present invention as described above, the cold air supplied to the refrigerating compartment is supplied with the cold air from the rear to the front by the conventional cold air supply structure, and the cold air is also supplied from the freezer compartment door side, and thus the three-dimensional cold air is provided in front and rear of the refrigerating compartment. Since the temperature of the whole refrigerating chamber can be maintained uniformly, the uniform refrigerating effect can be obtained for the whole refrigerating chamber.

또한 도어측의 온도감지에 의해 도어유로를 통하여 도어측으로 공급되는 냉기에 의하여, 도어바스켓에 보관중인 식품에 직접 냉기를 분출할 수 있게 되어, 특히 도어바스켓의 신선도 유지에 유리하다. 이러한 잇점은 도어의 빈번한 개폐에 의하여 온도가 상승하기 쉬운 도어바스켓 부분에 충분한 냉기를 공급할 수 있게 되어, 그곳에 보관하는 식품의 신선도를 유지할 수 있게 되는 효과가 기대된다.In addition, by the cold air supplied to the door through the door flow path by the temperature sensing on the door side, it is possible to directly eject the cold air to the food stored in the door basket, it is particularly advantageous to maintain the freshness of the door basket. This advantage is able to supply sufficient cold air to the portion of the door basket which is easy to increase the temperature by frequent opening and closing of the door, it is expected that the effect of maintaining the freshness of the food stored there.

그리고 냉장실의 도어의 개폐에 의하여 외부공기는 냉장고의 내부로 유입되지만, 이 때 외기는 냉장실의 전방부분에 주로 머물게 되는데, 본 고안에 의하면, 도어유로에서 후방으로 냉기가 분출되도록 되어 있기 때문에, 온도가 상대적으로 높은 전방부분을 신속하게 냉각시킬 수 있게 되는 잇점이 기대된다.The outside air flows into the inside of the refrigerator by opening and closing the door of the refrigerating compartment. At this time, the outside air stays mainly in the front part of the refrigerating compartment. According to the present invention, since the air is ejected backward from the door flow path, the temperature The advantage is that it is possible to quickly cool the relatively high front part.
