Description
본 발명은 냉장고의 냉동실 냉기공급장치에 관한 것으로, 보다 상세하게는 냉동실의 후측에 설치되는 냉동실팬과 냉동실루버의 구조를 개선하여 냉기유동에 의한 소음을 저감시키고 냉동실 내의 냉각효율을 높일 수 있도록 한 냉장고의 냉동실 냉기공급장치에 관한 것이다.The present invention relates to a freezer compartment cold air supply device of a refrigerator, and more particularly, to improve the structure of a freezer compartment fan and a freezer compartment installed at a rear side of a freezer compartment to reduce noise caused by cold air flow and to increase the cooling efficiency in the freezer compartment. It relates to a freezer compartment cold air supply device of the refrigerator.
일반적으로 잘 알려져 있듯이 냉장고의 냉동싸이클구조를 보면, 압축기에 의해 압축되어 고온고압으로 기체화된 냉매는 응축기를 거치면서 외부공기와의 열교환에 의해 열방출되어 액화되며, 상기 응축기로 부터의 액화냉매는 드라이어와 캐필러리튜브를 통과하면서 불순물과 수분등이 제거된 상태로 저온저압의 차가운 액상냉매를 이루어 냉동실 후측에 형성된 냉각기실 내의 냉각기로 보내진다.As is well known in general, in the refrigeration cycle structure of a refrigerator, a refrigerant compressed by a compressor and gasified at high temperature and high pressure is liquefied by heat release by heat exchange with external air while passing through a condenser, and liquefied refrigerant from the condenser. After passing through the dryer and the capillary tube, impurities and moisture are removed to form a cold liquid refrigerant at low temperature and low pressure, which is sent to the cooler in the cooler chamber formed at the rear side of the freezing chamber.
상기 냉각기를 통과하는 저온저압의 액화냉매는 냉동실과 냉장실에서 온도상승되어 냉기귀환덕트를 통해 귀환된 냉기와 냉각기에 의해 열교환되며 상기 귀환냉기와 열교환되면서 가스화된 냉매는 어큐뮬레이터를 거치면서 액상냉매는 어큐뮬레이터의 저면에 잔류되고 가벼운 기상냉매는 압축기로 보내져 압축기에 의해 고온고압으로 압축되는 냉매의 반복순환이 이루어진다.The low temperature and low pressure liquefied refrigerant passing through the cooler is elevated in temperature in the freezer compartment and the refrigerating compartment, and is heat exchanged by the cold and cooler returned through the cold air return duct. The light vapor phase refrigerant, which remains at the bottom of the chamber, is sent to the compressor and the circulation of the refrigerant compressed to high temperature and high pressure by the compressor is performed.
냉각기실 내의 냉각기에 의해 열교환된 차가운 냉기는 냉동실팬과 냉장실팬의 급속회전에 의해 냉동실 및 냉장실로 토출되게 된다.The cold cold heat exchanged by the cooler in the cooler chamber is discharged to the freezer compartment and the refrigerating chamber by rapid rotation of the freezer compartment fan and the refrigerating compartment fan.
도 1은 종래 기술에 따른 냉동실의 냉기공급장치를 나타낸 냉동실 정사시도로서, 도 1에 도시된 바와 같이 냉동실(100)의 후측에는 냉동실루버(10)와 루버절연물(20)이 설치되는데 상기 냉동실루버(10)의 상부에는 양측으로 다수의 냉기토출구(15)가 각각 형성되어 상기 냉기토출구(15)를 통해 냉각기실(50)에서 생성된 냉기가 냉동실(100) 고내로 토출되게된다.1 is a freezing chamber orthogonal view showing a cold air supply device of a freezing chamber according to the prior art, and as shown in FIG. A plurality of cold air discharge ports 15 are formed at both sides of the upper portion 10, respectively, and the cold air generated in the cooler chamber 50 is discharged into the freezer compartment 100 through the cold air discharge ports 15.
한편 냉동실(100) 하측으로는 냉기귀환덕트(60)가 형성되어있어 냉동실(100) 및 냉장실(미도시) 내에서 열교환된 냉기가 상기 냉기귀환덕트(60)를 통해 냉각기실(50)로 귀환되어 재차 열교환하여 냉각되는 순환을 반복한다.On the other hand, the cold air return duct 60 is formed below the freezer compartment 100 so that the cold air heat exchanged in the freezer compartment 100 and the refrigerating compartment (not shown) is returned to the cooler chamber 50 through the cold air return duct 60. The cycle of heat exchange and cooling again is repeated.
그러나 이러한 냉동실 냉기공급장치는 냉동실루버(10)와 냉동실팬(30) 사이의 간격이 좁고, 냉동실팬(30)이 냉동실루버(80)의 후측에 수직으로 설치되어 상기 냉동실팬(30)의 급속회전에 의해 냉동실(100) 고내로 토출되는 냉기가 고내로 토출되면서 상기 냉동실루버(10)의 후면에 부딪치게 되어 소음이 발생하는 문제점이 있어왔다.However, such a freezer compartment cold air supply device has a narrow gap between the freezing chamber 10 and the freezing chamber fan 30, and the freezing chamber fan 30 is vertically installed at the rear side of the freezing chamber 80 so that the freezing chamber fan 30 may be rapidly moved. As the cold air discharged into the freezer compartment 100 by the rotation is discharged into the inside of the freezer chamber, it hits the rear surface of the freezing chamber 10, causing noise.
상기한 문제점을 해결하기 위하여 본 발명 냉동실 냉기공급장치는 횡으로 다수의 팬날개가 구비된 원통형팬과 냉동실 내측으로 소정간격 돌출형성된 냉기토출구가 구비된 냉동실루버를 설치하여 냉동실내로 토출되는 냉기와 냉동실루버와의 접촉면적을 최소화하고 냉기가 토출되는 방향을 전방과 측방으로 분산시켜 소음발생을 최소화할 수 있는 냉동실 냉기공급장치의 제공을 그 기술적과제로 한다.In order to solve the above problems, the freezer compartment cold air supply device of the present invention is provided with a cold air discharged into the freezer compartment by installing a freezer chamber provided with a cylindrical fan having a plurality of fan blades in the horizontal direction and a cold air outlet formed by projecting a predetermined interval into the freezer compartment. The technical task of the present invention is to provide a freezer compartment cold air supply device capable of minimizing the generation of noise by minimizing the contact area with the freezing chamber and distributing the direction of cold air discharged forward and sideward.

The cylindrical fan 70 is transversely along the outer circumferential surface of the cylinder. As a result, a plurality of fan blades 71 are formed to supply cold air to the freezing chamber 100 by rapid rotation of the fan blades 71 on the cooler chamber 50 side.

It is installed to be inserted into the predetermined depth.
상기 팬하우징(85)의 전면에는 냉기가 토출될 수 있도록 다수개의 전면토출구(81)가 형성되고 측면에는 다수개의 측면토출구(82)가 각각 형성된다.A plurality of front discharge ports 81 are formed on the front surface of the fan housing 85 so that cold air can be discharged, and a plurality of side discharge ports 82 are formed on the side surfaces thereof.
