Description

냉장고의 냉동실 루버구조Freezer Louver Structure of Refrigerator

본 고안은 냉장고의 냉동실 루버에 관한 것으로 보다 상세하게는 냉동실 루버의 냉기유입공을 통해 유입되는 냉기의 흐름을 개선하고 역류를 방지할 수 있도록한 냉장고의 냉동실 루버구조에 관한 것이다.The present invention relates to a freezer compartment louver of a refrigerator, and more particularly, to a freezer compartment louver structure of a refrigerator capable of improving the flow of cold air introduced through a cold air inlet of the freezer compartment louver and preventing backflow.

일반적으로, 냉장고의 냉동실 배면에 설치되는 냉장실 루버는 그 후측의 루버 절연물과 함께 냉동실과 냉각기 사이를 차단함과 동시에 냉장실로 냉기를 공급하고 귀환시키는 통로를 형성하고 있다.In general, the refrigerating chamber louver installed at the rear of the freezer compartment of the refrigerator, along with the louver insulation on the rear side thereof, blocks the freezer compartment and the cooler and forms a passage for supplying and returning cold air to the refrigerating compartment.

이와 같은 냉장고의 냉동실의 루버는 제1도의 도시와 같이, 상부에는 송풍팬(25)과 직통되는 냉기토출구(9)와 그 바로 하측에 횡으로 연설된 다수의 냉기토출구(8)가 형성되고 하부에는 상기 냉기토출구(9)(8)를 통해 토출된 냉기가 열교환된 후 냉각기(30)측으로 복귀하도록 한 통로로서 다수의 냉기유입구(7)가 형성된다.As shown in FIG. 1, the louver of the freezer compartment of the refrigerator has a cold air outlet 9 directly connected to the blower fan 25 and a plurality of cold air outlets 8 extending laterally immediately below the lower part of the refrigerator. There are a plurality of cold air inlets 7 formed as a passage through which the cold air discharged through the cold air discharge ports 9 and 8 exchanges heat and then returns to the cooler 30 side.

그리고, 그 후측에는 제2도의 도시와 같이 루버절연물(20)가 일정간격을 두고 형성되는데 루버절연물(20)의 하부에도 상기 루버(10)의 냉기유입구(7)와 대향되는 냉기흡입구(22)이 설치되어 있다.In addition, the rear side of the louver insulator 20 is formed at a predetermined interval as shown in FIG. 2, and the cold air inlet 22 facing the cold air inlet 7 of the louver 10 is also formed under the louver insulator 20. Is installed.

이와 같이된 냉장고의 냉장실의 냉기순환사이클은, 제3도의 도시와 같이, 냉각기(30)측의 냉기가 송풍팬(25)에 의해 흡입되어 루버(10) 상측의 냉기토출구(8)(9)를 통해 냉동실(40)로 토출되어 열교환 된후 루버(10) 하부에 형성된 냉기유입구(7) 및 루버절연물(20)의 냉기흡입구(22)를 통해 냉각기(30)로 복귀하는 냉기순환이 반복되게 된다.In the cold air circulation cycle of the refrigerator compartment of the refrigerator as described above, as shown in FIG. 3, cold air on the cooler 30 side is sucked by the blower fan 25, and the cold air discharge ports 8 and 9 on the upper side of the louver 10 are provided. After being discharged to the freezing chamber 40 through heat exchange, the cold air circulation is returned to the cooler 30 through the cold air inlet 7 and the cold air inlet 22 of the louver insulator 20 formed under the louver 10. .

그러나, 이러한 종래 냉장고의 냉동실(40) 냉기복귀통로는 루버(10)의 냉기유입구(7)와 루버절연물(20)의 냉기흡입구(22)가 일직선상에 형성되어 있어서, 냉각기(30) 제상시 제상히터(35)의 복사열에 의한 온기가 이를 통하여 유입됨으로써 온기에 의해 루버(10)의 냉기유입구(7)가 결로현상이 초래되고 제상후에는 다시 결빙되는 과정에서 냉기귀환통로의 일부 또는 전부가 폐쇄되는 문제점은 물론 냉각효율이 저하되는 문제점이 있어 왔다.However, the cold air return passage of the freezer compartment 40 of the conventional refrigerator is formed in a straight line with the cold air inlet 7 of the louver 10 and the cold air inlet 22 of the louver insulator 20, so that the cooler 30 is defrosted. As the warm air by the radiant heat of the defrost heater 35 is introduced therethrough, the cold air inlet 7 of the louver 10 causes condensation due to the warm air, and part or all of the cold air return passage is frozen during defrosting. There has been a problem that the cooling efficiency is lowered as well as the problem of closing.

본 고안은 상기한 문제점을 감안하여 안출된 것으로서, 냉장고의 제상시에 제상히터에 의한 온기가 냉동실로 유입되지 않고 루버의 냉기유입구의 결로현상이 방지될 수 있도록 냉동실 루버의 구조를 개선하는 것을 그 기술적 과제로 한다.The present invention has been made in view of the above-mentioned problems, and it is to improve the structure of the freezer compartment louver so that the warm air by the defrost heater does not flow into the freezer compartment during defrosting of the refrigerator and the condensation of the cold air inlet of the louver can be prevented. It is a technical problem.

이하, 본 고안을 선호된 실시예에 따라 도시한 도면을 참조하여 보다 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제4도는 본 고안의 냉동실 배면의 분리사시도이고, 제5도는 본 고안에 따른 냉장고의 냉동실 냉기흐름을 도시한 냉장고의 종단면도로서, 냉장고의 냉동실(40) 배면을 형성하며 그 상부에는 송풍팬(25)과 직통되는 냉기토출구(9)와 그 하측에 횡으로 다수의 냉기토출구(8)가 형성되며 하부에는 다수의 냉기유입구(7)가 형성된 장방형의 루버(10)와, 그 후측에 일측 상부에는 팬설치공(21)이 형성되고 하부에는 냉기흡입구(22)가 형성된 장방형의 루버절연물(20)이 설치되게 된다.4 is an exploded perspective view of the rear surface of the freezer compartment of the present invention, and FIG. 5 is a longitudinal sectional view of the refrigerator showing the freezer cold flow of the refrigerator according to the present invention, and forms a rear surface of the freezer compartment 40 of the refrigerator, and a blower fan at the top thereof. Cold air discharge port (9) that is in direct communication with 25) and a plurality of cold air discharge ports (8) formed laterally on the lower side and a rectangular louver (10) formed with a plurality of cold air inlets (7) at the lower side, and one side upper portion at the rear side The fan installation hole 21 is formed in the lower portion of the rectangular louver insulator 20 having the cold air inlet 22 is installed.

그리고, 본 고안의 루버(10)에는 상기 루버(10) 배면의 냉기유입구(7) 외측에 상기 냉기유입구(7)보다 높은 위치에 개구(2)를 형성한 우회수단(1)을 루버(10)의 배면에 설치하여서된 것이다.In addition, the louver 10 of the present invention has a bypass means 1 having an opening 2 formed at a position higher than the cold air inlet 7 outside the cold air inlet 7 on the rear surface of the louver 10. It is installed on the back of the).

또한, 상기 우회수단(1)의 개구(2)에는 외측에 고무 또는 합성수지재의 얇은 플렙(3)을 설치하여 상기 개구(2)가 루버절연물(20)측으로만 개방되도록한 것이다.In addition, the opening 2 of the bypass means 1 is provided with a thin flap 3 of rubber or synthetic resin material on the outside so that the opening 2 is opened only to the louver insulator 20 side.

그리고 상기루버(10) 배면의 냉기유입구(7)상측과 하측에 각각 횡으로 고정홈(5)을 형성하고 상측의 고정홈(5)에는 고정턱(4')을 형성하며 상기 우회수단(1)의 상단부는 상기 고정턱(4')에 대응되는 걸림턱(4)을 형성하여 상기 우회수단(1)의 상단부에 형성된 걸림턱(4)이 상기 루버(10)의 냉기유입구(7) 상측에 형성된 고정홈(5)에 강제로 삽입되어 상기 고정턱(4')에 걸려짐과 동시에 상기 우회수단(1)의 하단이 상기 루버(10)의 냉기유입구(7) 하측에 형성된 고정홈(5)에 끼워짐으로써 상기 우회수단(1)이 루버(10) 배면의 냉기유입구(7) 외측에 고정되는 것이다.In addition, the fixing grooves 5 are formed in the upper and lower sides of the cold air inlet 7 on the rear surface of the louver 10, and the fixing jaw 4 ′ is formed in the upper fixing grooves 5, and the bypass means 1 The upper end of the () forming a locking jaw (4) corresponding to the fixing jaw (4 ') so that the locking jaw (4) formed on the upper end of the bypass means (1) is the upper side of the cold air inlet (7) of the louver (10) It is forcibly inserted into the fixing groove (5) formed in the fixing jaw (4 ') and at the same time the lower end of the bypass means (1) is formed in the fixing groove formed below the cold air inlet (7) of the louver ( 5) the bypass means 1 is fixed to the outside of the cold air inlet 7 on the rear surface of the louver 10.

이와 같은 본 고안의 루버구조를 채용한 냉장고의 냉동실의 냉기순환은, 먼저 냉각기(30)측의 냉기가 송풍팬(25)에 의해 흡입되어 루버(10) 상측의 냉기토출구(8)(9)를 통해 냉동실(40)로 토출되어 열교환된 후 루버(10) 하부에 형성된 냉기유입구(7)로 유입되는데, 본 고안에서는 냉기유입구(7) 외측에 우회수단(1)을 설치하였으며 우회수단(1)의 개구(2)는 상기 냉기유입구(7)보다 상측에 형성되어 있으므로 냉기유입구(7)를 통과한 냉기가 상측으로 상승하게 되고 우회수단(1)의 개구(2)를 통하여 상기 개구(2)보다 낮은 위치로 루버절연물(20)에 형성된 냉기흡입구(22)를 통하여 냉각기(30)측으로 복귀하고 냉각기(30)에 의해 차가워진 냉기는 다시 송풍팬(25)에 의해 상기와 같이 냉동실(40)로 토출되는 과정이 반복되는 순환싸이클을 이루게 된다.In the cold air circulation of the freezer compartment of the refrigerator employing the louver structure of the present invention, the cold air on the cooler 30 side is first sucked by the blower fan 25, and the cold air discharge ports 8 and 9 on the upper side of the louver 10 are provided. After being discharged to the freezing chamber 40 through the heat exchange to the cold air inlet (7) formed in the lower louver 10, in the present design, the bypass means (1) is installed outside the cold air inlet (7) and the bypass means (1 (2) is formed above the cold air inlet (7), the cold air passing through the cold air inlet (7) rises to the upper side and through the opening (2) of the bypass means (1) through the opening (2) The cold air cooled by the cooler 30 is returned to the cooler 30 through the cold air intake 22 formed in the louver insulator 20 to a position lower than), and the freezing chamber 40 is again performed by the blower fan 25 as described above. The discharge process is repeated to form a cycle.

한편, 냉각기의 성에를 제거하기 위하여 제상히터가 작동되면 제상히터(35)의 복사열에 의해 냉각기(30)가 가열되어 성에가 제거되게 되고 냉각기 주위의 공기온도가 상승되게 되는데, 본 고안에서는 루버(10)의 냉기유입구 배면에 우회수단(1)을 설치하였으므로 냉동실(40) 냉기 귀환 통로가 일직선으로 형성되지 않았으므로 제상히터(35)에 의해 가열된 온기가 냉동실(40)측으로 거의 유입되지 않게되고, 더욱이 온기가 냉동실(40)측으로 진행되더라도 우회수단(1)의 개구(2)에 설치된 플랩(3)에 의해 개구(2)가 차단되므로 냉동실루버(10)에는 전혀 영향을 미치지 못하게 되는 것이다.Meanwhile, when the defrost heater is operated to remove the frost of the cooler, the cooler 30 is heated by the radiant heat of the defrost heater 35 so that the frost is removed and the air temperature around the cooler is increased. Since the bypass means 1 is installed on the rear surface of the cold air inlet 10, the freezer compartment 40 is not formed in a straight line so that the warm air heated by the defrost heater 35 is hardly introduced into the freezer compartment 40 side. Further, even when the warmth proceeds to the freezing chamber 40 side, the opening 2 is blocked by the flap 3 provided in the opening 2 of the bypass means 1, so that the freezing chamber 10 is not affected at all.

따라서 냉각기(30) 제상시 제상히터(35)의 복사열에 의한 냉동실루버(10)의 결로현상이 방지되고 온기가 냉동실(40)내로 역류하는 것을 방지하여 냉장고의 냉각효율도 증대되는 것이다.Therefore, when the cooler 30 is defrosted, condensation of the freezing chamber 10 due to radiant heat of the defrost heater 35 is prevented, and the cooling efficiency of the refrigerator is also increased by preventing the warm air from flowing back into the freezing chamber 40.

이상에서 상세히 설명한 바와 같이, 본 고안의 냉동실 루버구조는 그 배면의 냉기유입구 외측에 냉기 우회수단을 설치함으로써, 제상시 냉동실로의 온기유입이 방지되어 루버의 냉기유입구측의 결로현상과 동결이 방지되어 원활한 냉기순환이 이루어지고 냉장고의 냉각효율을 일층 증대시킬 수 있는 것이다.As described in detail above, the freezer compartment louver structure of the present invention is provided with a cold air bypass means outside the cold air inlet on the rear side, thereby preventing the inflow of warm air into the freezer compartment during defrosting, thereby preventing condensation and freezing at the cold air inlet side of the louver. As a result, a smooth cold circulation is achieved and the cooling efficiency of the refrigerator can be further increased.

본 고안은 냉각기 제상시 제상히터의 복사열에 의한 온기가 냉동실 귀환통로를 통해 냉장실 루버의 냉기유입공으로 유입되는 것을 방지하여 루버의 냉기유입공의 빙결을 방지하고 냉각기의 효율을 증대시킬 수 있는 냉장고의 냉동실 루버의 구조를 제공하는 것을 그 목적으로 한다.The present invention prevents the warm air by radiant heat of the defrost heater during the defrosting of the cooler into the cold air inlet of the refrigerating chamber louver through the freezer return passage to prevent freezing of the louver's cold air inlet and increase the efficiency of the cooler. It is an object of the present invention to provide a structure of a freezer louver.
