Description
본 발명은 냉장고의 냉기공급구조에 관한 것으로서, 상세하게는, 사이드 바이 사이드형(side by side type) 냉장고의 도어부에 형성되는 냉기 덕트 및 냉기 토출구에 관한 것이다.The present invention relates to a cold air supply structure of a refrigerator, and more particularly, to a cold air duct and a cold air discharge port formed in a door part of a side by side type refrigerator.
일반적으로, 사이드 바이 사이드형 냉장고는 비교적 큰 용량을 가지고 여러가지 기능이 복합적으로 구비된 것으로, 냉동실과 냉장실이 각각 종방향으로 수직되게 냉장고의 좌우측에 설치되고 냉동실의 배면에는 증발기가 장착되는 냉각기실이 구비되어 냉동실과 냉장실의 고내 공기를 하부측으로 흡입함과 동시에 상부측으로 토출되게 하여 각 고내로 순환시킴으로써 냉장기능과 냉동기능을 각각 수행하도록 구성된 것이다.In general, the side-by-side type refrigerator has a relatively large capacity and is equipped with various functions, and the freezer compartment and the refrigerating compartment are installed at the left and right sides of the refrigerator such that the freezer compartment and the refrigerating compartment are vertically vertically respectively, and a cooler chamber having an evaporator mounted on the rear side of the freezer compartment. It is provided to suck the air in the freezer compartment and the refrigerating chamber to the lower side and discharged to the upper side at the same time to be configured to perform the refrigerating and freezing functions respectively by circulating into each chamber.
이러한 사이드 바이 사이드형 냉장고는 해당 고내에 각각 식품 등을 올려 보관하기 위한 선반이 상,하 선택적으로 이동가능하게 구성되고, 이들 중 상부측 선반의 하부에는 별도의 식품용기를 서랍식으로 수납하여 보관할 수 있도록 된 식품용기 수납장치가 구비된 것도 있다.These side-by-side refrigerators are configured to be selectively moved up and down in the shelves for storing foods, etc., respectively in the refrigerator, and among them, a separate food container may be stored in a lower part of the upper shelf. Some food containers are also provided.
도 1은 종래의 사이드 바이 사이드형 냉장고의 냉기순환장치의 구조를 도시한 종단면도이다.1 is a longitudinal sectional view showing the structure of a cold air circulation system of a conventional side-by-side refrigerator.
도시된 바와 같이, 종래의 사이드 바이 사이드형 냉장고의 냉기순환장치는 각각 수직으로 평행하게 형성되고 사절부(6)에 의해 분리구획되는 냉동실(F) 및 냉장실(R)과, 냉동실(F)의 후방에 냉동실(F)과 별개의 공간을 형성하도록 분리구획되고 증발기(2) 및 송풍팬(3)이 설치되는 냉각기실(1)과, 냉각기실(1)에서 생성된 냉기를 냉장실(R)로 공급하도록 사절부(6)의 상부측에 형성되는 공급덕트(4)와, 냉장실(R)에서 온도상승된 냉기가 냉각기실(1)로 귀환되는 통로로서 사절부(6)의 하부측에 형성되는 흡입덕트(6)와, 공급덕트(4)의 냉장실측에 설치되어 공급되는 냉기량을 조절하는 댐퍼(8)를 포함하여 구성된다.As shown, the cold air circulation system of the conventional side-by-side type refrigerator is formed in parallel to each other and separated by the trimming section 6, the freezer compartment (F) and the refrigerating chamber (R), and the freezer compartment (F) The cooler chamber 1 which is separated and formed so as to form a space separate from the freezing chamber F at the rear, and the evaporator 2 and the blower fan 3 are installed, and the cold air generated in the cooler chamber 1 is the refrigerating chamber R. The supply duct 4 formed at the upper side of the trimming section 6 so as to be supplied to the cooling section and a passage through which the cold air whose temperature has risen in the refrigerating chamber R is returned to the cooler chamber 1 at the lower side of the trimming section 6. And a damper (8) for adjusting the amount of cold air provided and provided on the refrigerating chamber side of the supply duct (4).
증발기(2)에서 생성된 냉기는 송풍팬(3)에 의해 냉동실(F) 및 냉장실(R)로 공급되고, 각 고내에 수납중인 저장식품 등과 열교환에 의해 온도상승된 냉기는 다시 증발기(2)측으로 귀환되는 순환을 반복하면서 냉장고내를 냉각시킨다.The cold air generated by the evaporator 2 is supplied to the freezing chamber F and the refrigerating chamber R by the blower fan 3, and the cold air that has risen in temperature by heat exchange with the stored foods stored in each chamber is evaporated again. The inside of the refrigerator is cooled while repeating the circulation returned to the side.
한편, 냉동실이 냉장실의 상부에 위치하는 일반적인 냉장고의 경우는 냉장실에서 온도상승된 냉기가 그 냉장실의 상부로서 냉동실의 배면에 위치하는 증발기로 귀환하는 구조를 취하므로, 냉기 토출구 및 흡입구의 구성에 상당한 제약이 있었지만, 사이드 바이 사이드형 냉장고의 경우는 냉장실에서 온도상승된 냉기가 단지 냉장실의 측면 임의의 위치에 형성된 냉기 흡입구를 통해 귀환되기만 하면 되므로, 보다 냉기 토출구 및 흡입구의 위치를 자유롭게 구성할 수 있다는 장점을 갖는다.On the other hand, in the case of a general refrigerator in which the freezer compartment is located at the upper part of the refrigerating compartment, since the cold air whose temperature has risen in the refrigerating compartment is taken back to the evaporator located at the back of the freezer compartment as the upper part of the refrigerating compartment, it is quite suitable for the configuration of the cold air discharge port and the suction port. In the case of side-by-side refrigerators, the cold air that has risen in the refrigerating compartment only needs to be returned through the cold air inlet formed at any position on the side of the refrigerating compartment, so that the positions of the cold air outlet and the inlet can be freely configured. Has an advantage.
따라서, 냉장실(R)의 내부에는 그 내부 전체의 고른 냉각을 위해서 복수개의 냉기 토출구가 형성되는 것이 제안되고 있는바, 도 1에 도시된 바와 같은 배면 토출구(9), 상면 토출구(10), 측면 토출구(11) 등이 그것이다.Therefore, it is proposed that a plurality of cold air discharge ports are formed inside the refrigerating chamber R for even cooling of the entire interior thereof, and the rear discharge port 9, the upper discharge port 10, and the side surface as shown in FIG. Discharge port 11 and the like.
실제에 있어서 냉장고의 사용시 가장 문제가 되는 것은 도어의 개폐에 따른 냉기손실이며, 냉장고 내부의 고른 온도분포를 위하여 특히 집중적인 냉각이 필요한 부분은 냉장고내에 수납되는 물품중 가장 출입이 빈번한 것이 수납되는 부분, 즉, 음료수가 저장되는 도어 바스켓 부분이라고 할 수 있다.In fact, the biggest problem when using the refrigerator is the loss of cold air due to the opening and closing of the door, and the part that needs intensive cooling especially for even temperature distribution inside the refrigerator is the part where the most frequent items are stored in the refrigerator. That is, it can be said that the portion of the door basket in which the beverage is stored.
그런데, 종래의 냉장고의 냉기공급구조에 있어서는 상기와 같은 도어부에 대한 냉기 토출구의 배치의 필요성을 무시하고 냉기공급구조를 구성하였으므로, 동일한 냉기의 양에 의해 냉장고의 내부를 효율적으로 냉각시키는 측면에 있어서 문제점으로 지적되어 왔다.However, in the conventional cold air supply structure of the refrigerator, the cold air supply structure is configured by ignoring the necessity of the arrangement of the cold air discharge ports as described above. Therefore, the side of the refrigerator is efficiently cooled by the same amount of cold air. Has been pointed out as a problem.
본 발명은 상기와 같은 문제점을 해결하여, 냉장고 내부의 고른 온도분포를 달성할 수 있는, 보다 효율적인 냉장고의 냉기공급구조를 제공함을 그 목적으로 한다.The present invention is to solve the above problems, to provide a more efficient cold air supply structure of the refrigerator, which can achieve an even temperature distribution inside the refrigerator.

도시된 바와 같이, 본 발명에 의한 냉장고의 냉기공급장치는 냉장실(R)의 후방 일측에 형성되어, 냉동실(미도시)로부터 유입된 냉기를 공급하는 공급 덕트(4)와; 공급덕트(4)로부터 전방을 향하여 냉장실(R)의 측면에 형성된 측면 덕트(22)와; 측면 덕트(22)의 전방 단부에 형성되어, 냉기를 공급하는 측면 공급구(23)와; 냉장실의 도어(D)의 내측면에 형성되어, 도어(D)의 폐쇄시 측면 공급구(23)와 연결되어 냉기를 공급받는 도어 흡입구(24)와; 도어 흡입구(24)에서 연장되어 도어(D)의 내부에 형성된 도어 덕트(25)와; 도어 덕트(25)의 중간 또는 단부에 형성되어, 도어(D)의 내측을 향하여 공급된 냉기를 토출하는 도어 토출구(26)를; 포함하여 구성된다.As shown, the cold air supply apparatus of the refrigerator according to the present invention is formed on the rear side of the refrigerating chamber (R), the supply duct (4) for supplying the cold air introduced from the freezing chamber (not shown); A side duct 22 formed on the side of the refrigerating chamber R toward the front from the supply duct 4; A side supply port 23 formed at the front end of the side duct 22 to supply cold air; A door suction port 24 formed on the inner side of the door D of the refrigerating compartment, connected to the side supply port 23 when the door D is closed, and receiving cold air; A door duct 25 extending from the door suction port 24 and formed inside the door D; A door discharge port 26 formed at the middle or the end of the door duct 25 to discharge cold air supplied toward the inside of the door D; It is configured to include.
또한, 도어 토출구(26)는 도어(D)의 내면에 설치된 도어 바스켓(14)을 향하여 냉기를 토출하도록 형성되는 것이 바람직하고, 나아가, 도어 토출구(26)는 도어 (D)의 내면 양측부에 형성되는 것이 바람직하다.In addition, the door discharge port 26 is preferably formed to discharge the cold air toward the door basket 14 provided on the inner surface of the door (D), furthermore, the door discharge port 26 is formed on both sides of the inner surface of the door (D). It is preferably formed.
이하, 본 발명에 의한 냉장고의 냉기공급구조의 동작에 관하여 설명한다.Hereinafter, the operation of the cold air supply structure of the refrigerator according to the present invention will be described.
냉동실(미도시)로부터 공급 덕트(4)를 통해 유입된 냉기는, 안내덕트 (21)를 통해 냉장실의 양측으로 분배되고, 측면 덕트(22)를 통해 측면 공급구(23)로 안내된다.The cold air introduced from the freezing chamber (not shown) through the supply duct 4 is distributed to both sides of the refrigerating chamber through the guide duct 21, and is guided to the side supply port 23 through the side duct 22.
냉장실의 도어(D)가 닫혀 있는 경우, 측면 공급구(23)는 도어 흡입구(24)와 맞대어져 연결되므로, 측면 덕트(22)를 통해 공급된 냉기는 도어 덕트(25)로 유입되어 도어 토출구(26)를 통해 냉장실의 내측을 향하여 토출된다.When the door D of the refrigerating compartment is closed, the side supply opening 23 is connected to the door inlet 24 so that the cool air supplied through the side duct 22 flows into the door duct 25 and the door discharge opening. Through 26, it is discharged toward the inside of the refrigerating chamber.
도어 토출구(26)가 도어(D)의 내면에 설치된 도어 바스켓(14)을 향하여 냉기를 토출하도록 도어(D)의 내면 양측부에 형성되는 경우, 도 2 및 도 3에 도시된 바와 같이, 측면 공급구(23a,23b)로부터 공급된 냉기는 도어의 폐쇄시 도어 흡입구 (24a,24b)로 공급되어, 도어(D)의 내면 양측부에 형성된 도어 토출구(26)로부터 도어 바스켓(14)을 향하여 토출된다.When the door discharge port 26 is formed on both sides of the inner surface of the door D to discharge cold air toward the door basket 14 installed on the inner surface of the door D, as shown in Figs. The cool air supplied from the supply ports 23a and 23b is supplied to the door suction ports 24a and 24b when the door is closed, and is directed toward the door basket 14 from the door discharge ports 26 formed on both inner sides of the door D. Discharged.
이와 같이, 도어 토출구(26)로부터 공급된 냉기는 직접적으로 도어 바스켓에 수납된 물품을 향하여 토출되므로, 냉장실에 수납되는 물품중 가장 그 출입이 빈번한 것이 저장되는 부분에 대한 집중냉각을 가능하게 한다.In this way, since the cold air supplied from the door discharge port 26 is discharged directly toward the article stored in the door basket, the centralized cooling of the portion of the article stored in the refrigerating chamber is most frequently stored.
따라서, 이는 냉장실 내부의 고른 온도분포를 가장 효율적인 방법으로 달성할 수 있도록 하는 것이다.Thus, it is possible to achieve an even temperature distribution inside the refrigerating compartment in the most efficient way.
이상에서는, 본 발명이 사이드 바이 사이드형 냉장고에 적용되는 경우를 실시례로 들어서 설명하였으나, 반드시 이에 한정되는 것은 아니며, 본 발명의 기본적인 기술적 사상은 기타 다른 타입의 냉장고의 경우에도 적용될 수 있다.In the above, the case in which the present invention is applied to the side-by-side type refrigerator has been described as an example, but is not necessarily limited thereto, and the basic technical idea of the present invention may be applied to other types of refrigerators.
본 발명은 냉장실에 수납되는 물품중 가장 출입이 빈번한 음료수 등이 수납되는 부분인 도어 바스켓 부위를 집중냉각할 수 있도록 함으로써, 냉장실 내부의 고른 온도분포를 짧은 시간 내에 달성할 수 있는, 보다 진일보한 냉장고의 냉기공급구조를 제시한다.The present invention enables the centralized cooling of the door basket portion, which is the portion in which the most frequently-drinked beverages and the like are stored among the items stored in the refrigerating compartment, thereby achieving even temperature distribution in the refrigerating compartment in a shorter time. The cold air supply structure is presented.
