본 발명은 냉장고의 냉기 토출구 형성구조에 관한 것으로서, 더욱 상세하게는 냉장고의 냉장실 후벽에 설치된 냉기 토출덕트의 덕트 사출물과 스치로폴로 된 단열재 사이의 사이뜸으로 냉기가 유입되지 않도록 냉기 토출구를 형성시킬 수 있도록 한 것이다.The present invention relates to a structure for forming a cold air discharge port of a refrigerator, and more particularly, to form a cold air discharge port so that cold air does not flow into the duct between the duct injection of the cold air discharge duct installed in the rear wall of the refrigerator and the insulation made of styropole. It would be.

일반적으로, 종래의 냉장고는 도 1 및 도 2에 나타낸 바와 같이, 본체(5)내의 상부 및 하부에 각각 냉동 및 냉장 식품 등을 보관하기 위한 냉동실(6) 및 냉장실(1)이 구획되도록 형성되고, 상기 본체(5)의 상부 및 하부에는 냉동실(6) 및 냉장실(1)을 개방 및 폐쇄하기 위한 냉동실 및 냉장실 도어(7)(8)가 설치되며, 상기 냉장실(1)의 내부에는 보관 식품이나 용기를 얹어 놓기 위한 복수개의 선반(9)이 일정한 간격으로 설치되고, 상기 냉장실(1)의 하부에는 채소류나, 과일 등을 담아 보관하기 위한 야채 박스(10)가 설치된다.In general, the conventional refrigerator is formed so that the freezer compartment 6 and the refrigerating compartment 1 for storing frozen and refrigerated food, etc., respectively, on the upper and lower portions of the main body 5, as shown in Figs. The upper and lower parts of the main body 5 are provided with a freezing compartment 6 and a refrigerating compartment door 7 and 8 for opening and closing the freezing compartment 6 and the refrigerating compartment 1, and the food stored inside the refrigerating compartment 1. In addition, a plurality of shelves 9 for placing a container are installed at regular intervals, and a vegetable box 10 for storing vegetables or fruits is installed in the lower part of the refrigerating chamber 1.

한편, 상기 냉장실(1)의 후벽에는 냉장실(1)의 내부로 냉기를 토출시키기 위한 냉기 토출덕트(12)가 설치되는 데, 냉기 토출덕트(12)의 덕트 사출물(13)의 전면에는 복수개의 냉기 토출구(3a)가 형성되고, 상기 덕트 사출물(13) 내의 단열재(14)에는 상기 냉기 토출구(3a)와 대응되는 냉기 토출구(4a)가 형성되어 상기 냉동실(6)의 후벽에 설치된 증발기(15)에서 냉각된 냉기가 팬모터(16)의 구동에 따른 팬(17)의 회전에 의해 냉동실(6)을 거쳐 상기 냉기 토출덕트(12) 내부의 냉기 유 로(W)를 통해 유입되는 냉기를 상기 단열재(14)와 덕트 사출물(13)의 냉기 토출구(4a)(3a)를 거쳐 냉장실(1)로 냉기를 토출시키게 된다.On the other hand, a cold air discharge duct 12 for discharging cold air into the refrigerating chamber 1 is installed on the rear wall of the refrigerating chamber 1, and a plurality of cold air discharge ducts 12 are provided on the front surface of the duct injection product 13 of the cold air discharge duct 12. The cold air discharge port 3a is formed, and the cold air discharge port 4a corresponding to the cold air discharge port 3a is formed in the heat insulating material 14 in the duct injection product 13, and the evaporator 15 installed on the rear wall of the freezer compartment 6 is provided. The cold air is cooled in the cold air flows through the cold air flow path (W) inside the cold air discharge duct 12 through the freezer compartment (6) by the rotation of the fan 17 according to the drive of the fan motor 16. The cold air is discharged to the refrigerating chamber 1 through the heat insulating material 14 and the cold air discharge ports 4a and 3a of the duct injection product 13.

그러나, 이와 같은 종래 냉기 토출덕트(12)의 냉기 토출구(3a)(4a)를 통해 나온 냉기의 일부는 냉장실(1)로 유입되지 않고 도 2에 도시된 바와 같이, 단열재(14)와 덕트 사출물(13) 사이의 약 1.5∼2㎜ 정도의 사이뜸(G)으로 냉기가 유입되어 덕트 사출물(13)을 과냉시키므로써 고내 온도(3℃)와 냉기 토출구(3a) 주위의 덕트 사출물(13) 표면 온도(-7℃)차가 크게 된다.However, a portion of the cold air discharged through the cold air discharge ports 3a and 4a of the conventional cold air discharge duct 12 does not flow into the refrigerating chamber 1, and as shown in FIG. 2, the heat insulating material 14 and the duct injection product are shown. The cold air flows into the gyroscope G of about 1.5 to 2 mm between (13) and supercools the duct injection product 13 so that the duct injection product 13 around the high temperature (3 ° C.) and the cold air discharge port 3a is discharged. Surface temperature (-7 degreeC) difference becomes large.

따라서, 이렇게 큰 온도 차이는 고내에 고온 다습한 부하가 투입시 고내 수증기를 냉기 토출구 주변에서 과포화 상태로 만들고 덕트 사출물(13)의 표면에서 응축되어 이슬을 발생시키게 되는 데, 이 이슬은 계속 냉각될 경우 결빙을 이루게 되며, 결빙은 성장하여 때때로 냉기 토출구(3a)를 폐쇄시키는 성능상의 문제점을 일으키기도 한다. Thus, such a large temperature difference causes the high-temperature and high-pressure loads to be supersaturated around the cold air outlet when condensed and condensation on the surface of the duct injection 13 generates dew, which continues to cool. If freezing occurs, the freezing grows and sometimes causes a performance problem of closing the cold air outlet 3a.

또한, 종래의 냉기 토출덕트(12)는 정면에서 관찰했을 때 덕트 사출물(13)의 냉기 토출구(3a) 사이로 단열재(14)가 약 1.5∼2.5㎜ 정도가 바로 노출되므로 미관상 고내 이미지를 저하시키게 되는 등의 문제점이 있었다. In addition, the conventional cold air discharge duct 12 is exposed from about 1.5 to 2.5 mm of the heat insulating material 14 directly between the cold air discharge ports 3a of the duct injection product 13 when viewed from the front, thereby reducing the aesthetic image. There was a problem.

따라서, 본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 냉장고의 냉장실 후벽에 설치된 냉기 토출덕트의 덕트 사출물과 스치로폴로 된 단열재 사이의 사이뜸으로 냉기가 유입되지 않도록 냉기 토출구를 형성시킬 수 있도록 하여 덕트 사출물이 과냉각됨에 따른 냉기 토출구 주위에 결빙 및 결로가 발생되는 현상을 방 지할 수 있는 냉장고의 냉기 토출구 형성구조를 제공하는 데 그 목적이 있다.Accordingly, the present invention is to solve the above-mentioned problems, by forming a cold air discharge port so that the cold air does not flow into the moxibustion between the duct injection of the cold air discharge duct installed in the rear wall of the refrigerator compartment and the insulating material of the styropole. It is an object of the present invention to provide a cold air outlet forming structure of a refrigerator which can prevent freezing and condensation from occurring around the cold air outlet as the duct injection is supercooled.

본 발명의 다른 목적은 덕트 사출물과 단열재의 조립후 냉기 토출구 주변으로 단열재가 노출되지 않도록 하므로써 미관을 미려하게 하여 냉장고의 이미지를 고급화하는 데 있다.Another object of the present invention is to enhance the image of the refrigerator by making the beauty of beauty by preventing the insulation from being exposed around the cold air outlet after assembling the duct injection product and the insulation.
