일반적인 냉장고는 제1도에 도시한 바와 같이, 외관을 형성하는 본체(10)와, 상기 본체 (10)내의 상,하측과 냉동실(20)과 냉장실(30)을 구획함과 동시에 증발기 (40)를 내장하여 상기 냉동 및 냉장실 (20)(30)과 연통되도록 형성된 단열부재(50)와, 상기 단열부재(50)의 후축에 상기 증발기(40)에 의해 열교환된 차가운 냉기가 상기 단열부재(50)의 내부를 통하여 상기 냉동 및 냉장실(20)(30)로 각각 순환되도록 전원을 인가받아 구동되는 냉기순환수단(60)과, 상기 냉동 및 냉장실(20)(30)의 내부공간을 칸칸이 구획하여 냉동 및 냉장식품(도시안됨)을 지지하는 다수개의 선반(70)과, 상기 단열부재(50)와 연통되게 연결하여 상기 선반(70)에 의해 칸칸이 구획된 냉동 및 냉장실(20)(30)내에 냉기의 공급을 안내하도록 장착된 댐퍼부재(80)와, 상기 냉동 및 냉장실(20)(30)내에 각각 저장보관된 냉동 및 냉장식품을 인출하기 위하여 냉동 및 냉장실(20)(30)의 전면개구에 개폐가능케 힌지결합된 냉동 및 냉장실도어(90)(91)로 이루어져 있다.As shown in FIG. 1, the general refrigerator divides the main body 10 forming the exterior, the upper and lower sides of the main body 10, the freezing chamber 20 and the refrigerating chamber 30, and the evaporator 40 at the same time. A heat insulation member 50 formed to communicate with the freezing and refrigerating chambers 20 and 30, and cold cold heat exchanged by the evaporator 40 in the rear shaft of the heat insulation member 50. Kankan partitions the internal space of the cold air circulation means 60 and the refrigeration and refrigerating chambers 20 and 30 that are driven by being supplied with power so as to be circulated to the freezing and refrigerating chambers 20 and 30 through the interior of the). A plurality of shelves 70 supporting frozen and refrigerated foods (not shown), and connected to the heat insulating member 50 to communicate with each other in the freezer and refrigerator compartments 20 and 30 in which compartments are partitioned by the shelves 70. In the damper member 80 and the freezing and refrigerating chambers 20 and 30, respectively, mounted to guide the supply of cold air. Chapter allows the opening and closing the front openings of the freezing and refrigerating compartment 20, 30 in order to withdraw the storage of frozen food and chilled consists of a freezing and refrigerating chamber door 90, 91 is hinged.
이때, 상기 단열부재(50)의 전측에는 상기 냉기순환수단(60)의 송풍력에 의해 냉동 및 냉장실(20)(30)내에 형성된 냉기가 단열부재(50)내에 내장된 증발기(40)를 통과하면서 재차 차가운 냉기로 열교환되도록 상,하부에 냉기유입구(51)가 각각 형성되어 있고, 그 후측에는 상기 냉기순환수단(60)의 송풍력에 의해 증발기(40)를 통과하면서 열교환된 냉기를 댐퍼부재(80)를 통해 냉동 및 냉장실(20)(30)내부로 토출시켜주도록 상,하부에 냉기출기(52)가 각각 형성되어 있다.At this time, cold air formed in the freezing and refrigerating chambers 20 and 30 by the blowing force of the cold air circulation means 60 passes through the evaporator 40 embedded in the heat insulating member 50 on the front side of the heat insulating member 50. While the cold air inlet 51 is formed at the upper and lower portions so as to be heat-exchanged with cold cold again, the rear side of the damper member exchanges the cold air heat-exchanged while passing through the evaporator 40 by the blowing force of the cold air circulation means 60. Cold air ejectors 52 are formed in the upper and lower portions of the cooling and refrigerating chambers 20 and 30 so as to be discharged through the 80.
상기 냉기순환수단(60)은 상기 냉동실(20)과 냉장실(30)의 사이에 장착되어 전원을 인가받아 구동되는 모터(61)와 상기 모터(61)의 구동력을 전달받아 회전되면서 차가운 냉기를 냉동 및 냉장실(20)(30)내에 각각 분배공급함과 동시에 냉동 및 냉장실(20)(30)내의 냉기를 단열부재(50)의 내부로 흡입하는 송풍팬(62)으로 이루어져 있다.The cold air circulation means 60 is mounted between the freezing chamber 20 and the refrigerating chamber 30 to rotate and receive a driving force of the motor 61 and the motor 61 driven by receiving power to freeze cold cold air. And a blower fan 62 for distributing and supplying each of the refrigerating chambers 20 and 30, and simultaneously sucking the cool air in the refrigerating and refrigerating chambers 20 and 30 into the heat insulating member 50.
상기 선반(70)은 상기 냉동실(20)과 냉장실(30)내의 양측벽에 돌출형성된 안내턱(도시안됨)에 의해 일정간격으로 칸칸이 지지되어 있다.The shelf 70 is supported by the kankan at regular intervals by guide jaws (not shown) protruding from both side walls of the freezing chamber 20 and the refrigerating chamber 30.
상기 댐퍼부재(80)의 전면에는 상기 냉동 및 냉장실(20)(30)의 내부로 냉기가 분출되도록 일정간격을 두고 다수개의 냉기토출구(81)가 형성되어 있고, 이 냉기토출구(81)에는 냉기의 토출흐름을 안내함과 동시에 선반(70)상에 재치된 식품에 의해 냉기토출구(81)가 막히는 것을 방지하도록 안내날개(82)가 돌출형성되어 있다.A plurality of cold air discharge outlets 81 are formed on the front surface of the damper member 80 at predetermined intervals so that cold air is ejected into the freezing and refrigerating chambers 20 and 30. The guide blade 82 protrudes so as to guide the discharge flow of the air and simultaneously prevent the cold air discharge port 81 from being blocked by the food placed on the shelf 70.
한편, 도면 중 미설명부호 100은 주응축기, 101은 보조응축기, 102는 압축기, 103은 제빙기이다.In the drawings, reference numeral 100 denotes a main condenser, 101 an auxiliary condenser, 102 a compressor, and 103 an ice maker.
그러나, 이와 같이 구성된 종래에 의한 냉장고의 선반장치는, 다수개의 평탄한 선반(70)이 제2도에 도시한 바와 같이 댐퍼부재(80)의 냉기토출구(81)와 겹쳐지지 않는 위치에서 냉장실(30)내부를 칸칸공간으로 구획함과 동시에 냉장식품이 상면에 재치될수 있도록 한 구조로 되어 있기 때문에 선반(70)상에 재치된 식품이 냉기토출구(81)와 근접될 경우 냉기토출구(81)에서 토출되는 냉기는 식품에 막혀 중앙으로 순환되지 못하고 주변으로 확산되면서 곧바로 단열부재(50)의 냉기유입구(51)로 유입되는 순환작용을 반복함에 따라 냉장실(30)내의 주변과 중앙의 냉기온도차가 심하게 발생되어 냉장효율을 저하시킨다는 문제점이 있으며, 또한 냉기토출구(81)와 근접된 식품은 토출되는 냉기에 의해 장시간 방치되므로 결빙된다는 문제점도 있었다.However, the conventional shelf apparatus of the refrigerator configured as described above has the refrigerator compartment 30 at a position where a plurality of flat shelves 70 do not overlap with the cold air outlet 81 of the damper member 80 as shown in FIG. Since the food is placed on the shelf 70 when the food placed on the shelf 70 is close to the cold air outlet 81, the food is discharged from the cold air outlet 81. As the cold air is blocked by the food and is not circulated to the center but diffuses to the surroundings, the cold air temperature difference between the surroundings and the center in the refrigerating chamber 30 is severely generated by repeating the circulation action immediately flowing into the cold air inlet 51 of the insulating member 50. There is a problem of lowering the refrigeration efficiency, and there is also a problem that the food in close proximity to the cold air discharge port 81 is frozen because it is left for a long time by the discharged cold air.
따라서, 본 고안은 상기 문제점을 해결하기 위하여 이루어진 것으로, 본 고안의 목적은, 댐퍼부재에서 토출된 냉기가 선반의 냉기유로를 따라 분포됨과 동시에 냉장실내부로 균일하게 분출되어 냉장효율을 상승시킴과 동시에 식품의 결빙현상을 미연에 방지하도록 한 냉장고의 냉기분포장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to simultaneously distribute the cold air discharged from the damper member along the cold air flow path of the shelf and to uniformly discharge the inside of the refrigerating chamber to increase the refrigerating efficiency.

이때, 댐퍼부재(80)의 냉기토출구(81)에서 곧바로 선반(110)의 내부로 공급되는 차가운 냉기는 제4도 및 제5도에 도시한 바와 같이 상부선반대(111)와 하부선반대(112)의 결합에 의해 통로가 형성된 덕트부(112c)를 넓게 분포되면서 그 덕트부(112c)의 바닥면에 형성된 다수개의 냉기분출구(112d)를 통하여 하부선반대(112)의 하부측으로 분출되어 냉장실(30)내의 균일한 냉기온도를 유지시켜 줌으로써 일정식품을 향해 집중되는 냉기분출을 방지하여 식품의 결빙현상을 미연에 방지함과 동시에 냉장효울을 상승시켜 주게 되는 것이다.At this time, the cold cool air supplied to the inside of the shelf 110 directly from the cold air discharge outlet 81 of the damper member 80, as shown in FIGS. 4 and 5 the upper shelf 111 and the lower shelf ( The duct part 112c in which the passage is formed by the coupling of 112 is widely distributed, and is ejected to the lower side of the lower shelf 112 through a plurality of cold air outlets 112d formed on the bottom surface of the duct part 112c. By maintaining a uniform cold air temperature in (30) to prevent the cold air concentration concentrated on a certain food to prevent the freezing phenomenon of food in advance and to increase the refrigeration effect.
이때, 선반의 덕트부(112c)를 따라 냉기가 분포되므로 냉기의 분산으로 인한 냉기의 유출속도의 저하를 방지하여 냉기가 선반의 하측 먼곳까지 도달하게 하므로, 냉장실내의 온도 분포를 더욱 균일하게 할 수 있다.At this time, since the cold air is distributed along the duct portion 112c of the shelf, the cold air flow rate is prevented from being lowered due to the distribution of the cold air, and thus the cold air reaches the far side of the bottom of the shelf, thereby making the temperature distribution in the refrigerating chamber more uniform. Can be.
이상에서 설명한 바와 같이 본 고안에 의한 냉장고의 냉기분포장치에 의하면, 선반수반의 뚜께내부로 공급된 차가운 냉기가 넓게 분포됨과 동시에 하부측을 향해 분출되어 냉장실내의 균일한 냉기온도를 유지시켜 주도록 다수개의 냉기분출구를 갖는 덕트부가 형성된 구조로 되어 있기 때문에 일정식품을 향해 집중되는 냉기분출을 방지하여 식품의 결빙현상을 미연에 방지함과 동시에 냉장효율을 상승시켜 줄수 있는 효과가 있다.As described above, according to the cold air distribution device of the refrigerator according to the present invention, the cold air supplied to the inside of the cover of the shelf is widely distributed and blows toward the lower side to maintain a uniform cold air temperature in the refrigerator compartment. Since the duct section having two cold air outlets is formed, it is possible to prevent cold air from being concentrated toward a certain food, thereby preventing freezing of food and increasing the refrigeration efficiency.
