본 고안은 냉장고의 냉기유출 차단장치에 관한 것으로, 더욱 상세하게는 냉장고의 도어를 열게 되면 냉장고의 전방 상면으로부터 하측 수직방향으로 냉기를 토출시켜 냉장고내의 냉기가 외부로 유출되는 것을 차단할 수 있도록 된 냉장고의 냉기유출 차단장치에 관한 것이다.The present invention relates to a cold air leakage blocking device of the refrigerator. More specifically, when the door of the refrigerator is opened, the refrigerator is configured to discharge cold air from the front upper surface of the refrigerator to the lower vertical direction to prevent the cold air from leaking to the outside. It relates to a cold air leakage blocker of.
일반적으로 냉장고의 사용에 있어 안에 저장되어 있던 내용물을 꺼내고자 냉장고도어를 열게 되면 냉장고도어가 열려 있는 동안 안에 있던 냉기가 외부로 유출되고 외부의 더운 공기가 냉장고내로 유입되므로써 냉장고내의 내부온도가 상승되게 된다. 이에 따라 냉장고의 제어장치는 상승된 온도를 다시 하강시키기 의해 콤프레셔등에 의한 냉동싸이클을 가동시켜 손실된 내부의 온도를 보상하게 되는 바, 냉장고내에 저장되어있던 음식물등은 접촉온도가 자주 변하게 되면 신선도가 떨어지게 되는 문제가 발생되고, 냉기유출에 따른 보상작용을 위해 불필요한 전력이 소모되는 문제가 발생되었다.Generally, when the refrigerator door is opened to take out the contents stored in the refrigerator, the inside temperature of the refrigerator is increased by the flow of cold air to the outside while hot air is introduced into the refrigerator while the refrigerator door is open. do. Accordingly, the controller of the refrigerator compensates for the lost internal temperature by operating the refrigeration cycle by a compressor or the like by lowering the elevated temperature again. When the contact temperature is frequently changed, the freshness of the food stored in the refrigerator is fresh. The problem of falling occurs, and the problem of unnecessary power consumption to compensate for the cold air outflow occurred.
그리하여 종래에는 냉장효과를 높힐 수 있을 뿐만 아니라 냉장고도어를 열어도 외부로 유출되는 냉기의 양을 줄이기 위해 3면 입체냉장고 즉 냉장고 내측의 좌우측면과 후면에서 안쪽으로 냉기를 토출하도록 된 냉장고를 개발하였으나 냉장고도어의 개방에 따른 냉장고내측의 전방에 있는 냉기를 단속하는데는 역부족이었고, 종래 다른 방법으로는 냉장고내측에 회전식 팬을 설치하여 냉장고도어를 열게되면 상기 회전식팬이 동작되어 냉기가 안에서 맴돌도록 하므로써 냉기의 유출량을 줄이도록 된 것도 개발되어 있으나, 이는 내부의 냉기를 가두는데는 효과적이나 냉장고 도어측의 냉기는 외부로 유출된다는 문제점이 있었다.Therefore, in order to increase the refrigerating effect in the past, in order to reduce the amount of cold air flowing out even when the refrigerator door is opened, a three-sided refrigerator, that is, a refrigerator that discharges cold air from the left and right sides and the rear side of the refrigerator, has been developed. It was inadequate to control the cold air in front of the inside of the refrigerator according to the opening of the refrigerator door. In the conventional method, when the refrigerator door is opened by installing a rotary fan inside the refrigerator, the rotary fan is operated to allow the cold air to hover inside. It has been developed to reduce the amount of cold air flow, but this is effective to trap the internal cold air, but there was a problem that the cold air on the refrigerator door side is leaked to the outside.
본 고안은 상기한 사정을 감안하여 안출한 것으로, 냉장고도어를 열게 되면 냉장실의 상부 입구로 부터 수직하방으로 냉기를 토출시켜 냉장실 입구 전면에 수직으로 냉기차단층을 형성시키므로써 냉장실 내측의 냉기가 외부로 유출되지 못하도록 하기 위하여 냉장실의 상부입구 일측에 냉기토출구를 형성시키고 냉장고 후부의 냉기유입닥트 일측에 유로변경용 댐퍼를 설치하여 냉장실도어가 열릴때 상기 유로변경용 댐퍼가 작동되어 냉장실팬에 의해 순환되는 냉기가 냉장실상측토출구로 공급되어 냉장실 전면에서 직하방으로 토출되도록 이루어진 냉장고의 냉기유출 차단장치를 제공하고자 함에 고안의 목적이 있다.The present invention was devised in view of the above circumstances, and when the refrigerator door is opened, cold air is discharged vertically downward from the upper inlet of the refrigerating compartment to form a cold air blocking layer vertically in front of the inlet of the refrigerating compartment. Cold flow outlet is formed at one side of the upper inlet of the refrigerating chamber and a flow changing damper is installed at one side of the cold air inlet duct at the rear side of the refrigerator to open the refrigerating chamber door. It is an object of the present invention to provide a cold air outflow blocking device of the refrigerator, wherein the cold air is supplied to the outlet of the upper side of the refrigerating compartment and discharged directly from the front side of the refrigerating compartment.
이하 본 고안의 구성 및 작용효과에 대하여 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter will be described in detail with reference to the drawings for the configuration and effect of the present invention.
본 고안은 냉장실팬(10)에 의한 냉장실(200) 공급용 냉기의 순환닥트(12)중 냉장실 상부와 후부 양방향으로 분지되는 닥트(16)(18)의 분지점에 그 중 일방향으로 닥트를 개로하는 댐퍼(14)를 설치하고, 상기 댐퍼(14)는 냉장실도어스위치(20)에 연동되어 냉장실도어(202)가 열리면 상부 닥트(16)로 유로를 개로하고 냉장실도어(202)가 닫혀있으면 후부닥트(18)로 유로를 개로하도록 된 구조로 되어 있다.The present invention is to open the duct in one direction of the branch of the duct (16, 18) branched in both the upper and rear of the refrigerating chamber of the circulation duct 12 of the cold air for supplying the refrigerating chamber 200 by the refrigerating chamber fan (10). The damper 14 is installed, and the damper 14 is interlocked with the refrigerating chamber door switch 20, and when the refrigerating chamber door 202 is opened, the channel is opened by the upper duct 16 and the rear side of the refrigerating chamber door 202 is closed. The duct 18 is configured to open the flow path.
미설명 부호 102는 냉동실도어, 160은 냉기흡입구를 나타낸다.Reference numeral 102 denotes a freezer compartment door, 160 denotes a cold air intake port.
제1도는 본 고안에 종래의 냉장고에 있어 예컨대 3면 입체 냉장고에 대한 냉기의 흐름을 설명하기 위한 냉장고의 축단면도를 도시한 것이다.1 shows an axial sectional view of a refrigerator for explaining a flow of cold air, for example, for a three-sided three-dimensional refrigerator in a conventional refrigerator according to the present invention.
통상 냉장고는 냉동실(100)과 냉장실(200) 및 그의 도어(102)(202)로 이루어져 있고, 도시되지 않은 냉기발생장치로 부터 발생되는 냉기가 순환팬(140)의 구동에 따라 냉동실(100)과 냉장실(200)로 공급되어 각각 설정된 저온을 유지하도록 되어 있다. 여기서 순환팬(140)이라 함은 냉장실 냉기공급용 팬 또는 냉동실 냉기공급용 팬을 일컫는다.In general, the refrigerator includes a freezer compartment 100, a refrigerating compartment 200, and doors 102 and 202 thereof. The freezer compartment 100 is driven by the circulating fan 140 in which cold air generated from an unillustrated cold air generator is driven. And supplied to the refrigerating chamber 200 to maintain the set low temperatures, respectively. Here, the circulation fan 140 refers to a refrigerating chamber cold air supply fan or a freezing chamber cold air supply fan.
이러한 냉장고에 있어 냉기의 흐름은 도시된 도면중 화살표방향으로 순환되도록 되어 있는 바, 대개 상층에 배치되는 냉동실의 후부에 설치되는 순환팬(140)의 구동에 의거 냉기가 유입되면 냉동실(100)에서는 냉동실(100) 후방으로 부터 내측으로 유입되어 전방 하방으로 되돌아나가고, 냉장실(200)에 있어서는 냉장실(200)의 후방상측과 좌우측면 및 전방하측으로 부터 토출되어 실내온도를 설정온도로 유지하면서 전방상부에 설치되는 흡입구(160)를 통해 되돌아 나가도록 되어 있다.In the refrigerator, the flow of cold air is circulated in the direction of the arrow in the drawing, and in the freezer compartment 100 when cold air is introduced by driving the circulation fan 140 installed at the rear of the freezer compartment, which is disposed on the upper floor. It flows inward from the rear of the freezing chamber 100 and returns to the front downward, and in the refrigerating chamber 200 is discharged from the rear upper and left and right sides and the front lower side of the refrigerating chamber 200 while maintaining the room temperature at the set temperature. It is to go back through the suction port 160 is installed in.
그러나 이와 같은 구조에 있어 냉장실(200)의 도어(202)를 열게 되면 냉장실(200)의 후방이나 측방으로 부터 송풍되어 나오는 냉기가 전면으로 유출되고 외부의 온도가 유입되어 결국 냉장실(200)의 온도가 상승되어진다.However, in such a structure, when the door 202 of the refrigerating compartment 200 is opened, the cold air blown out from the rear or the side of the refrigerating compartment 200 flows out to the front side and the outside temperature flows into the front, resulting in the temperature of the refrigerating compartment 200. Is raised.
따라서 앞서 설명된 바와 같이 냉장실(200)의 도어(202)를 자주 여닫게 되면 냉장실(200)의 냉장기능이 떨어지게 되어 내측에 저장되어 있던 음식물등의 신선도가 저하되어진다.Therefore, as described above, if the door 202 of the refrigerating compartment 200 is frequently opened and closed, the refrigerating function of the refrigerating compartment 200 is lowered, and the freshness of food and the like stored therein is lowered.
제2도는 본 고안에 따른 냉장고에 있어 냉기의 흐름을 설명하기 위하여 냉장고의 측단면도를 도시한 것이다.2 is a side cross-sectional view of the refrigerator to explain the flow of cold air in the refrigerator according to the present invention.
여기서는 도시되지 않은 냉기발생장치로 부터 발생된 냉기가 냉동실(100)의 후방으로 유입되어 냉장실(200)의 상부와 냉장실(200)의 후방하측으로 분지되는 닥트(12)의 분지점에 냉기흐름제어용 댐퍼(14)가 설치되어 있다. 상기 댐퍼(14)는 평소에는 전방으로 끌어당겨져 종래와 마찬가지로 상부의 냉기가 냉장실(200)의 후방하부로 공급될 수 있도록 하지만 후술되는 바와 같이 냉장실(200)의 도어(202)가 열리게 되면 도면에 도시된 바와 같은 상태로 이동되어 냉기가 냉장실(200)의 후방하측으로 공급될 수 있는 유로 즉 닥트(18)를 차단하는 한편 냉장실(200)의 상부닥트(16)측으로 유로를 개방하는 작용을 한다.In this case, the cold air generated from the cold air generating device (not shown) flows into the rear of the freezing compartment 100 and is controlled at the branch point of the duct 12 branched to the upper portion of the refrigerating chamber 200 and the rear lower side of the refrigerating chamber 200. The damper 14 is provided. The damper 14 is usually pulled toward the front to allow the cold air of the upper portion to be supplied to the rear lower portion of the refrigerating chamber 200 as in the prior art, but when the door 202 of the refrigerating chamber 200 is opened as described below, It moves to a state as shown to block the flow path that the cold air can be supplied to the rear lower side of the refrigerating chamber 200, that is, the duct 18, while opening the flow path to the upper duct 16 side of the refrigerating chamber 200. .
제3도는 본 고안에 따른 회로도를 도시한 것으로, 냉장고의 전반적인 기능제어동작을 수행하는 주제어부(300)에 냉장실도어스위치(20)가 연결되어 있고, 또한 냉장실도어스위치(20)에는 그의 온오프에 따라 연동되어 작동되는 실내등(320)(340)이 연결되어 있으며, 상기 주제어부(300)의 다른 출력단에는 냉장실팬(10)이 연결되어 있다.Figure 3 shows a circuit diagram according to the present invention, the refrigerator compartment door switch 20 is connected to the main control unit 300 for performing the overall function control operation of the refrigerator, and the refrigerator compartment door switch 20 on and off Indoor lights 320 and 340 that are linked to operate according to the connection, and the refrigerating chamber fan 10 is connected to the other output terminal of the main control unit 300.
냉장실팬(10)은 일반적인 냉동싸이클에 따라 주제어부(300)의 제어에 의거 동작되지만, 본 고안에 따른 동작을 수행함에 있어서는 냉장실도어스위치(20)가 온될때 즉 냉장실(200)의 도어(202)가 열렸을때 주제어부(300)의 제어에 의거 냉장실팬(10)이 구동된다.The refrigerating chamber fan 10 is operated based on the control of the main control unit 300 according to a general freezing cycle, but in performing the operation according to the present invention, when the refrigerating chamber door switch 20 is turned on, that is, the door 202 of the refrigerating chamber 200. Is opened, the refrigerating chamber fan 10 is driven under the control of the main control unit 300.
즉, 냉장실도어(202)가 열리게 되면 냉장실 도어스위치(20)가 온상태로 접속되고 이에 따라 댐퍼(14)가 구동되어 냉기의 유로방향이 냉장실(200) 상부 닥트(16)로 변경된다. 또한 냉장실도어스위치(20)의 온상태 접속에 따라 주제어부(300)가 이를 감지하여 냉장실팬(10)을 작동시킨다.That is, when the refrigerating chamber door 202 is opened, the refrigerating chamber door switch 20 is connected to the on state, and the damper 14 is driven accordingly to change the flow direction of the cold air to the upper duct 16 of the refrigerating chamber 200. In addition, the main control unit 300 detects this according to the on-state connection of the refrigerator compartment door switch 20 to operate the refrigerator compartment fan 10.
그리하여 냉동실(100) 상부로 부터 유입되는 냉기는 댐퍼(14)에 의한 유로변경에따라 냉기순완닥트(12)에서 상부 닥트(16)를 통해 냉장실(200) 상부 입구쪽의 흡입구(160)를 통해 냉장실(200)전면에서 직하방으로 토출되어 냉장실(200) 입구 전면에는 냉기차단층이 형성되며, 그에 따라 냉장실(200)내의 냉기가 외부로 유출되지 못하고 내부에 머물게 된다.Thus, the cold air flowing from the upper part of the freezing chamber 100 is changed from the cold air duct 12 through the upper duct 16 through the suction port 160 toward the upper inlet of the refrigerating chamber 200 according to the flow path change by the damper 14. A cold air blocking layer is formed on the front surface of the inlet of the refrigerating chamber 200 by being discharged downward from the front side of the refrigerating chamber 200, and thus, the cold air in the refrigerating chamber 200 does not leak to the outside and stays inside.
따라서 냉장실(200)내의 냉기는 냉장실도어(202)의 개방에 대하여도 별다른 변화를 가져오지 않게 되므로 냉장실(200)내의 음식물이 그대로 신선도를 유지할 수 있게 되는 것이다.Therefore, since the cold air in the refrigerating compartment 200 does not bring about a change with respect to the opening of the refrigerating compartment door 202, the food in the refrigerating compartment 200 can maintain the freshness as it is.
상기한 바와 같이 본 고안은 냉장실도어의 개방에 따라 연동되는 댐퍼를 냉기순환닥트의 일측에 설치하고, 냉장실도어가 열렸을때 냉장실팬의 작동에 따라 송출되는 냉기가 상기 댐퍼의 유로변경에 의해 냉장실입구 상부로 부터 직하방으로 토출되어 냉기차단막을 형성하므로써 냉장실내의 냉기가 유지되고 그에 따라 전력소모가 줄어드는 효과가 있다.As described above, the present invention provides a damper interlocked with the opening of the refrigerating chamber door on one side of the cold air circulation duct, and when the refrigerating chamber door is opened, the cold air discharged according to the operation of the refrigerating chamber fan is changed by changing the flow path of the damper. By discharging downward from the top to form a cold air barrier film, the cold air in the refrigerating chamber is maintained, thereby reducing power consumption.
