Refrigerators for supplying cold cold air are as shown in FIGS. 1 and 2.

즉, 중간벽(1)의 상측에 위치하는 냉동실(2) 후벽측에는 증발기(3a)와 송풍팬(3b)을 포함한 통상의 냉각실(3)이 설치되고, 그 냉각실(3)의 전방측에는 상기 증발기(3a)를 통과한 찬 냉기를 냉동실(2) 및 냉장실(4)에 분배공급하기 위한 쉬라우드와 그릴팬(5)이 부착되며, 그 쉬라우드와 그릴팬(5)이 상측에 냉동실 토출구(5a)가 형성되고, 상기 중간벽(1)의 전방측 상단면에 냉동실 흡입구(1a)(1a')가 형성되며, 그 냉동실 흡입구(1a)(1a')와 연통되어 상기 냉각실(3)로 관통되는 냉동실 냉기귀환유로(1b)(1b')가 상기 중간벽(1)의 내부에 구비된다.That is, a normal cooling chamber 3 including an evaporator 3a and a blower fan 3b is provided on the rear wall side of the freezing chamber 2 located above the intermediate wall 1, and the front side of the cooling chamber 3 is provided. The shroud and grill pan 5 for distributing and supplying cold cold air passing through the evaporator 3a to the freezing compartment 2 and the refrigerating compartment 4 are attached, and the shroud and grill pan 5 are located above the freezing compartment.

반면, 상기 중간벽(1)의 하측에 위치하는 냉장실(4)은, 상기 냉각실(3)과 연통되는 냉장실 안내덕트(미도시)가 중간벽을 상하로 관통하여 멀티덕트(6)와 연통되고, 그 멀티덕트(6)의 상측에는 냉기의 양을 조절하는 댐퍼(7)가 설치돼며, 상기 냉장실(4)의 소정위치에는 수개의 선반(8)이 장착되고, 상기 멀티덕트(6)의 각 선반(8) 사이에는 멀티덕트 토출구(6a)가 형성되며, 상기 중간벽(1)의 전방 하단면에는 냉장실 흡입구(1c)가 형성되고, 그 냉장실 흡입구(1c)와 연통되는 냉장실 냉기귀환유로(1d)가 상기 냉각실(3)까지 중간벽(1)을 관통,형성되어 있다. 이때, 상기 중간벽(1)의 내부에는 상기 냉동실 및 냉장실 냉기귀환유로(1b)(1b')(1d)가 함께 형성되어 있으나, 그 두 냉기귀환유로(1b)(1b')(1d)가 서로 중첩되지 않도록 하기 위해 통상 도 3에 도시된 바와 같이, 냉장실 냉기귀환유로(1d)가 중앙에 형성되고, 그 냉장실 냉기귀환유로(1d)의 양측에 냉동실 냉기귀환유로(1b)(1b')가 형성되어 있다.On the other hand, in the refrigerating chamber 4 positioned below the intermediate wall 1, a refrigerating chamber guide duct (not shown) communicating with the cooling chamber 3 penetrates the intermediate wall up and down to communicate with the multi duct 6.

Is formed.

도면중 미설명 부호인 (D)(D')(9)(10)는 각각 냉동실 및 냉장실 도어와 야채박스, 그리고 냉동실 감온센서이다.Reference numerals (D) (D ') (9) and 10 (not shown) in the drawings are a freezer compartment, a refrigerator compartment door, a vegetable box, and a freezer compartment temperature sensor, respectively.

상기와 같이 구성된 냉장고의 냉기유로에 있어서 냉기의 순환과정을 살펴보면 도 2에 도시된 바와 같다.Looking at the circulation process of the cold air in the cold air flow path of the refrigerator configured as described above is as shown in FIG.

상기 증발기(3a)를 거치면서 형성된 찬 냉기는 상기 송풍팬(3b)에 의해 쉬라우드와 그릴팬(5)의 냉동실 토출구(5a)를 통과하여 냉동실(2)로 토출되고, 그 일부는 상기 쉬라우드와 그릴팬(5)에 부딪혀 자연낙하 하면서 냉장실 안내덕트를 거쳐 멀티덕트(6)에 유입되며, 그 멀티덕트(6)에 유입된 찬 냉기는 각각의 멀티덕트 토출구(6a)를 통해 각 칸으로 분출된다.Cold air formed while passing through the evaporator 3a is discharged to the freezing chamber 2 through the freezing chamber discharge port 5a of the shroud and the grill pan 5 by the blowing fan 3b, and part of the cold air is discharged. While hitting the wood and grill pan (5), the natural cold falls into the multi-duct (6) via the refrigerating chamber guide duct, the cold air introduced into the multi-duct (6) through each compartment through the respective multi-duct outlet (6a) Is blown out.

여기서, 냉동실(2)로 유입된 냉기는 상기 냉동실내를 순회한 다음에 냉동실 흡입구(1a)(1a')에 흡입되어 냉동실 냉기귀환유로(1b)(1b')를 거쳐 냉각실로 분출되고, 그 분출돈 냉기는 상기 송풍팬(3b)에 의해 흡상되면서 재냉각되는 것이었다. 또한, 상기 냉장실 안내덕트를 거쳐 멀티덕트(6)로 유입되는 찬냉기는, 각각의 멀티덕트 토출구(6a)를 통해 냉장실 내로 분출되어 칸칸마다를 순회하면서 더워져 상승하게 되고, 그 상승하는 더워진 냉기는 상기 중간벽(1)의 전방 하당면에 형성된 냉장실 흡입구(1c)에 흡입되어 냉장실 냉기귀환유로(1d)를 거쳐 상기 냉각실(3)로 분출,재냉각 되는 것이었다.Here, the cold air introduced into the freezer compartment 2 is circulated in the freezer compartment and then sucked into the freezer compartment suction ports 1a and 1a 'and is ejected into the freezer compartment through the freezer compartment cold air return flow passages 1b and 1b'. Blowing air was sucked by the said blowing fan 3b, and was recooled. In addition, the cold coolant flowing into the multi-duct 6 through the refrigerating chamber guide duct is ejected into the refrigerating chamber through each of the multi-duct discharge port (6a), it is warmed up as it travels through each compartment, and the rising hot The cold air is sucked into the refrigerating chamber suction port 1c formed on the front lower surface of the intermediate wall 1, and is blown into the cooling chamber 3 through the refrigerating chamber cold air return flow path 1d and recooled.

이때, 상기 냉장고의 운전을 제어하는 방식이 냉동실 온도기준 제어방식인 경우에는 도 2에 도시된 바와 같이, 냉동살(2)의 상면에 냉동실 감온센서(10)를 부착하고, 그 센서(10)의 설정온도(통상 -18℃로 설정됨)에 냉동실의 온도가 도달하면 상기 냉장고는 냉장실의 온도에 관계없이 오프(OFF)되는 것이었다. 따라서, 상기와 같은 냉동실 온도기준 제어방식에서는 냉장실(4)에 고온의 부하를 투입하여도 냉자실(4)의 온도상승을 인식하지 못하는 문제점이 있었던 바, 이러한 문제점을 해결하기 위하여 냉장실 온도기준 제어방식이 제시되었다.In this case, when the method of controlling the operation of the refrigerator is a freezer compartment temperature reference control scheme, as shown in FIG. 2, a freezer compartment temperature sensor 10 is attached to an upper surface of the freezer flesh 2, and the sensor 10 of FIG. When the temperature of the freezer compartment reached the set temperature (normally set to −18 ° C.), the refrigerator was turned off regardless of the temperature of the refrigerator compartment. Therefore, in the freezer compartment temperature reference control method as described above, there is a problem in that the temperature rise of the cold compartment 4 is not recognized even when a high temperature load is put into the refrigerator compartment 4. The method was presented.

상기 냉장실 온도기준 제어방식은, 냉장실(4)의 소정위치에 냉장실 온도를 설정온드(통상 0℃~10℃)내로 유지하기 위한 냉장실 감온센서(미도시)를 부착하여 냉장실의 온도변화에 의해 냉장고가 운전되도록 하므로, 부하대응 능력이 냉동실 온도기준 제어방식보다는 상당히 개선되는 효과가 있었다.In the refrigerating compartment temperature reference control method, a refrigerator compartment temperature sensor (not shown) for maintaining the refrigerating compartment temperature at a predetermined temperature (typically 0 ° C. to 10 ° C.) at a predetermined position of the refrigerating compartment 4 is attached to the refrigerator by changing the temperature of the refrigerating compartment As a result, the load response capability was significantly improved over the freezer temperature reference control method.

그러나, 상기와 같은 종래의 냉장실 온도기준 제어방식 역시 냉장고의 전체분위기 온도에 따라 냉장고가 운전을 하게 되는 것으로, 상기 냉장실(4)이 개발시 이미 각 칸 마다의 일정한 냉기분배비가 결정되어 있으므로 인해 기존부하(즉,이미 냉각되어 있는 식품)나 새로이 투입된 고온의 부하에 동일한 양의 냉기가 토출되게 되어 기존에 냉각되어 있던 식품은 과냉현상이 발생하게 되는 반면에 고온의 부하는 냉각되는데 상당한 시간이 소요되는 문제점이 있었다.However, in the conventional refrigerator compartment temperature reference control method as described above, the refrigerator is operated according to the overall atmosphere temperature of the refrigerator. The same amount of cold air is discharged to the load (ie, food that has already been cooled) or to a newly-loaded high temperature load, so that the previously cooled food is overcooled, while the high temperature load takes considerable time to cool down. There was a problem.

따라서, 상기 냉동실 및 냉장실에 투입되는 부하의 크기에 따라 냉장고의 운전여부가 제어되며, 특히 냉장실 내의 온도를 세밀하게 감지하여 각 칸마다에 투입되는 부하의 크기에 따라 냉기를 차별적으로 공급하므로써, 식품의 과냉은 물론 냉각시간을 축소할 수 있는 냉장고의 집중 냉각방법 및 그 장치를 제고하는 것이 본 발명의 목적이다.Therefore, the operation of the refrigerator is controlled according to the size of the load put into the freezer compartment and the refrigerating compartment, and in particular, by detecting the temperature in the refrigerating compartment finely and differentially supplying the cold air according to the size of the load put into each compartment, It is an object of the present invention to improve the centralized cooling method and apparatus of the refrigerator that can reduce the cooling time as well as the supercooling.

상기 중앙집중 냉각유로(42)의 하단부에는 중앙냉각 냉기토출구(42a)가 형성되고, 상기 하단집중 냉각유로의 하단에는 하단냉각 냉기토출구(44a)가 형성되며, 상기 각각의 냉기토출구(42a)(44a)에는 덕트선반(35,35')이 삽입되어 냉기를 공급받도록 형성된다.A central cooling cold air outlet 42a is formed at a lower end of the centralized cooling channel 42, and a lower cooling cold air outlet 44a is formed at a lower end of the lower centralized cooling channel 42, respectively. 44a), the duct shelves 35 and 35 'are inserted to receive cold air.

여기서, 냉기를 냉장실(30)에 차별적으로 분배,공급하기 위하여 상기 냉기분배막(43)이 상측에서 회동가능하게 설치되어 멀티덕트(40)를 개폐하는 냉기차단막 조립체(41)는, 냉기차단막(41a)과, 그 냉기차단막(41a)을 회동시키며 상기 감온센서(21,31,32,33,34)와 전기적으로 연결되는 차단막 구동모터(41b)으로 구성된다.Here, the cold air barrier membrane assembly 41 which opens and closes the multi duct 40 by rotatably installed above the cold air distribution membrane 43 so as to differentially distribute and supply cold air to the refrigerating chamber 30 may include a cold air barrier membrane ( 41a) and a blocking film driving motor 41b which rotates the cold air blocking film 41a and is electrically connected to the temperature sensor 21, 31, 32, 33, 34.

상기와 같이 구성되는 본 발명의 집중 냉각장치의 동작을 설명하기 위하여 도 4에서 도 7 그리고 도 8이 인용된다.4 to 7 and 8 are cited to explain the operation of the centralized cooling apparatus of the present invention configured as described above.

즉, 압축기(미도시)가 운전을 개시하면 냉매가 증발기(22a)에서 주위로부터 열을 흡수하는 과정에서 찬 냉기가 생성되고, 그 찬 냉기의 일부는 송풍팬(22b)에 의해 냉동실(20)로 토출되어 냉동실(20)을 선회한 다음에 다시 중간벽(1) 내에 형성된 냉동실 냉기귀환유로(1b)를 통해 냉각실(22)의 하측부로 유도되며, 그 일부는 멀티덕트(40)를 통해 냉장실(30)로 유입되어 선회한 다음 다시 중간벽(1) 내의 냉장실 냉기귀환유로(1d)를 통해 냉각실(3)로 유입된다. 여기서, 냉동실(20)가 냉장실(30)을 선회하는 찬 냉기는 상기 냉동실 및 냉장실에 수납된 음식물 등과 접촉하여 열교환이 이뤄지고, 그 과정에서 냉동실 감온센서(21)와 냉장실 센서(31,32,33,34)에 의해 감지되며, 그 감지된 온도와 각 센서의 설정온도를 비교하여 냉장고를 정지시키든지 아니면 냉기차단막(41)을 회동시켜 과부하기 걸린 수납칸에 찬 냉기를 집중공급하게 되는 것이다.That is, when the compressor (not shown) starts to operate, cold air is generated while the refrigerant absorbs heat from the surroundings in the evaporator 22a, and a part of the cold air is stored in the freezing chamber 20 by the blower fan 22b. Is discharged to the freezing chamber 20 and then guided to the lower portion of the cooling chamber 22 through the freezing chamber cold air return flow path 1b formed in the intermediate wall 1, a part of which is transferred through the multi duct 40. It flows into the refrigerating chamber 30 and turns, and then flows into the cooling chamber 3 again through the refrigerating chamber cold air return passage 1d in the intermediate wall 1. Here, the cold cool air in which the freezer compartment 20 turns the refrigerating compartment 30 is in contact with food stored in the freezer compartment and the refrigerating compartment, and the heat exchange is performed. In the process, the freezer temperature sensor 21 and the refrigerating compartment sensors 31, 32, and 33 34 is detected by comparing the detected temperature and the set temperature of each sensor to stop the refrigerator or rotate the cold air barrier 41 to concentrate the cold air in the overloaded storage compartment.

도 7및 도 8은 냉동실의 설정온도가 -18℃이고, 냉장실의 설정온도가 3℃일 경우에, 상기와 같이 칸칸마다 다른 양의 냉기를 공급받게 되는 과정을 보다 상세히 설명하기 위하여 제시된 것이다.7 and 8 are presented to explain in more detail the process of receiving a different amount of cold air for each compartment as described above, when the set temperature of the freezer compartment is -18 ℃, and the set temperature of the refrigerating chamber is 3 ℃.

상기 냉장실 및 냉동실 감온센서에 의해 냉장실의 온도와 냉동실의 온도가 각각 설정온도 이하로 도달하게되면, 압축기가 자동으로 정지하게되어 냉장고가 오프(OFF)된다. 그러나, 상기 냉장실의 온도는 설정온도에 도달하였으나, 냉동실의 온도가 설정온도보다 크게 되면, 상기 냉동실 감온센서에 의해 냉기차단막이 도 7의 P2와 같이 멀티덕트(40)를 전폐(全閉)시켜 냉동실의 온도를 하강시키게 되며, 반대로 냉장실의 온도가 설정온도보다 크게 되면, 상기 냉동실 감은센서에 의해 냉기차단막이 도 7의 P2와 같이 멀티덕트(40)를 전폐(全閉)시켜 냉동실의 돈도를 하강시키게 되며, 반대로 냉장실의 온도가 설정온도보다 크게 되면, 일단 냉기차단막(41a)이 도 7의 P1와 같이 멀티덕트(40)를 전개(全開)시키고, 그 중에서 특히 부하가 높은 곳을 추적하게 된다. 즉, 중앙칸의 조합온도가 하단칸의 조합온도에 비해 임의의 허용온도차보다 크게 되면, 다시말해 중앙칸에 허용온도차보다 큰 고온의 음식물이 수납되면 냉기차단막(41a)은 도 7의 P3와 같은 형태로 회동하여 중앙집중 냉각상내로 변환되고, 반면에 하단칸에 허용온도차보다 큰고온의 음식물이 수납되면 냉기차단막(41a)은 도 7의 P4와 같은 형태로 회동하여 하단집중 냉각상태로 변환하게 되는것이다.When the temperature of the refrigerating compartment and the freezing compartment reaches the set temperature or less by the refrigerating compartment and the freezing compartment temperature sensor, respectively, the compressor is automatically stopped and the refrigerator is turned off. However, although the temperature of the refrigerating compartment has reached the set temperature, when the temperature of the freezing compartment is greater than the set temperature, the cold air barrier membrane is completely closed by the freezing compartment temperature sensor as shown in P2 of FIG. 7. When the temperature of the freezer compartment is lowered, and the temperature of the freezer compartment is greater than the set temperature, the cold air blocking membrane completely closes the multi duct 40 as shown in P2 of FIG. On the contrary, when the temperature of the refrigerating chamber becomes larger than the set temperature, the cold air blocking membrane 41a fully develops the multi duct 40 as shown in P1 of FIG. Done. That is, when the combined temperature of the central compartment is greater than a certain allowable temperature difference compared to the combined temperature of the lower compartment, that is, when the food of a higher temperature than the allowable temperature difference is accommodated in the central compartment, the cold air barrier membrane 41a has the same shape as P3 of FIG. When rotated and converted into the centralized cooling bed, on the other hand, when food of a high temperature larger than the allowable temperature difference is accommodated in the lower compartment, the cold air barrier 41a rotates in the form as shown in P4 of FIG. .

이상에서 설명한 바와 같이 본 발명에 의한 냉장고의 집중 냉각방법 및 그 장치는, 냉동실의 소정위치에 냉동실 감온센서를 설치하고, 냉장실의 각 선반 사이에 냉장실 감온센서를 설치하며, 상기 감온센서와 연뎔되어 증발기에서 생성되는 찬 냉기를 냉장실에 차별적으로 공급하기 위하여 멀티덕트 내에서 회동하면서 투입되는 부하의 크기에 따라 멀티덕트를 개폐하는 냉기차단막을 설치함으로써, 기존의 냉각된 식품의 과냉은 물론 새로이 수납된 식품의 냉각시간을 축소할 수 있는 효과가 있다.As described above, the intensive cooling method and apparatus of the refrigerator according to the present invention are provided with a freezer compartment temperature sensor at a predetermined position of the freezer compartment, a refrigerator compartment temperature sensor between each shelf of the refrigerator compartment, and connected to the temperature sensor. In order to differentially supply cold and cold air generated in the evaporator to the refrigerating chamber, a cold air barrier is installed to open and close the multi duct according to the load input while rotating in the multi duct. There is an effect that can reduce the cooling time of food.
