종래의 냉장고에 있어서, 냉동실에 선반이 장착되는 냉장고의 일반적인 구성은 도 1에 도시된 바와 같다.In a conventional refrigerator, a general configuration of a refrigerator in which a shelf is mounted in a freezer compartment is as shown in FIG. 1.
즉, 중간벽(1)의 상측에 위치하며 그 중간 지점에 냉동실 선반(2a)이 장착된 냉동실(2)의 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 쉬라우드(5) 및 그릴팬(6)이 부착되며, 그 그릴팬(6)의 상측에 냉동실 토출구(6a)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 구비되어 있다.That is, the conventional cooling chamber 3 including the evaporator 3a and the blower fan 3b is located on the rear wall side of the freezing chamber 2, which is located above the intermediate wall 1 and is equipped with a freezing chamber shelf 2a at its intermediate point. In the front side of the cooling chamber 3, a shroud 5 and a grill pan 6 for distributing and supplying cold cold air having passed through the evaporator 3a to the freezing chamber 2 and the refrigerating chamber 4 are provided. And a freezer compartment discharge port 6a is formed on the grill pan 6, and a freezer compartment suction port 1a, 1a 'is formed on the front upper surface of the intermediate wall 1, and the freezer compartment suction port Freezing chamber cold air return passages 1b and 1b ', which communicate with 1a) and 1a' and penetrate the cooling chamber 3, are provided inside the intermediate wall 1.
한편, 상기 중간벽(1)의 하측에 위치하는 냉장실(4)은, 상기 냉각실(3)과 연통되는 냉장실 안내덕트(미도시)가 중간벽을 상하로 관통하여 멀티덕트(7)와 연통되고, 상기 냉장실(4)의 소정 위치에는 수개의 선반(8)이 장착되며, 상기 멀티덕트(7)의 각 선반(8) 사이에는 멀티덕트 토출구(도면에는 3개)(7a)가 형성되고, 상기 중간벽(1)의 전방 하단면에는 냉장실 흡입구(1c)가 형성되며, 그 냉장실 흡입구(1c)와 연통되는 냉장실 냉기귀환유로(1d)가 상기 냉각실(3)까지 중간벽(1)을 관통, 형성되어 있다.On the other hand, in the refrigerating chamber 4 located below the intermediate wall 1, a refrigerating chamber guide duct (not shown) communicating with the cooling chamber 3 passes through the intermediate wall up and down to communicate with the multi duct 7. And a plurality of shelves 8 are mounted at predetermined positions of the refrigerating chamber 4, and a multi duct discharge port (three in the drawing) 7a is formed between each shelf 8 of the multi duct 7. A refrigerator compartment inlet port 1c is formed at the front lower end surface of the intermediate wall 1, and a refrigerator compartment cold air return flow path 1d communicating with the refrigerator compartment inlet port 1c extends to the cooling chamber 3. It penetrates and forms.
이때, 상기 도 1에서는 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 2에 도시된 바와 같이, 냉장실 냉기귀환유로(1d)가 중앙에 형성되고, 그 냉장실 냉기귀환유로(1d)의 양측에 냉동실 냉기귀환유로(1b)(1b')가 형성되어 있다.In this case, the freezing chamber and the refrigerating chamber cold air return passages 1b, 1b ', and 1d are formed together inside the intermediate wall 1, but the two cold air return passages 1b and 1b' ( In order to prevent 1d) from overlapping each other, as shown in FIG. 2, a refrigerating chamber cold return channel 1d is formed in the center, and the freezer compartment cold return channel 1b is formed on both sides of the refrigerating chamber cold return channel 1d. 1b ') is formed.
도면중 미설명 부호인 (D)(D')(9)는 각각 냉동실 및 냉장실 도어와 도어포켓과 야채 박스이다.Reference numerals (D) (D ') 9 in the drawings denote freezer compartments and refrigerator compartment doors, door pockets, and vegetable boxes, respectively.
상기와 같이 구성된 냉장고에 있어서, 상기 냉동실의 냉기 순환과정을 살펴보면 도 1에 도시된 바와 같다.In the refrigerator configured as described above, the cold air circulation process of the freezer compartment is as shown in FIG. 1.
즉, 상기 증발기(3a)를 거치면서 형성된 찬 냉기는 상기 송풍팬(3b)에 의해 그릴팬(6)의 냉동실 토출구(6a)를 통과하여 냉동실(2)로 토출되고, 그 일부는 그릴팬(6)의 후면에 부딪혀 자연낙하 하면서 냉장실 안내덕트(미도시)를 거쳐 멀티덕트(7)에 유입되며, 그 멀티덕트(7)에 유입된 찬 냉기는 각 멀티덕트 토출구(7a)를 통해 각 칸으로 분출된다.That is, cold cool air formed while passing through the evaporator 3a is discharged through the freezer compartment discharge port 6a of the grill pan 6 by the blower fan 3b to the freezer compartment 2, a part of which is the grill fan ( 6) is hit by the back of the natural fall while passing through the refrigerating chamber guide duct (not shown) through the multi-duct (7), the cold air flowing into the multi-duct (7) through each compartment through the respective multi-duct outlet (7a) Is blown out.
여기서, 상기 냉동실(2)의 상측 후방에서 전방측으로 토출된 냉기는 냉동실(2)내의 선반(2a) 상,하부를 순회한 다음에 냉동실 흡입구(1a)(1a')에 흡입되어 냉동실 냉기귀환유로(1b)(1b')를 거쳐 냉각실로 분출되고, 그 분출된 냉기는 상기 송풍팬(3b)에 의해 흡상되면서 재냉각되는 것이었다.Here, the cold air discharged from the upper rear to the front of the freezer compartment 2 is circulated in the upper and lower parts of the shelf 2a in the freezer compartment 2 and then sucked into the freezer compartment suction port 1a (1a ') to return to the freezer compartment cold air flow path. (1b) and (1b ') were blown into the cooling chamber, and the blown cold air was recooled while being sucked up by the blowing fan 3b.
그러나, 상기와 같은 종래의 냉장고에 있어서, 상기 냉동실(2)로 유입되는 냉기의 일부가 냉동실 선반(2a)에 의해 냉동실(2)의 상부에서 정체되어 수납물에 찬냉기를 충분히 공급하지 못하게 될 우려가 있었다.However, in the conventional refrigerator as described above, a part of the cold air flowing into the freezer compartment 2 is stagnated at the upper part of the freezer compartment 2 by the freezer compartment 2a, and thus, the cold refrigerator is not sufficiently supplied to the objects. There was concern.
또한, 상기 냉동실(2)의 냉기흡입구(1a, 1a')가 중간벽(1)의 상측면, 즉 냉동실(1)의 전방 하단면에 형성되므로, 식품 적재시 그 적재된 수납물에 의해 상기 냉기흡입구(1a)(1a')가 막혀 냉기의 원활한 순환을 방해하는 것은 물론 상기 수납물에서 수분이 발생될 경우 그 수분이 냉기귀환유로(1b)(1b')로 유입되어 결빙될 우려가 있었다.In addition, since the cold air suction openings 1a and 1a 'of the freezing chamber 2 are formed on the upper side of the intermediate wall 1, that is, the front lower surface of the freezing chamber 1, The cold air intakes 1a and 1a 'are blocked to prevent smooth circulation of the cold air, and when water is generated in the storage, the water may flow into the cold air return passages 1b and 1b' and freeze. .
따라서, 본 발명의 목적은 냉동실로 유입되는 냉기가 선반의 상,하부에서 원활하게 순환되도록 하여 수납물에 충분한 냉기를 공급할 수 있도록 하는데 있다.Therefore, an object of the present invention is to allow the cool air flowing into the freezer compartment to be circulated smoothly in the upper and lower parts of the shelf to supply sufficient cold air to the storage.
또한, 상기 냉동실에 식품 적재시 그 적재된 수납물에 의해 냉기흡입구가 막히지 않도록 하여 냉기가 원활하게 귀환되도록 하는 것은 물론 수납물에서 발생되는 수분에 의해 냉기귀환유로가 결빙되는 것이 미연에 방지되도록 하는데 있다.In addition, when the food is loaded in the freezer compartment, the cold air intake port is not blocked by the loaded goods so that the cold air is smoothly returned, and the freezing air return flow path is prevented from freezing by the moisture generated in the goods. have.
