The refrigerating chamber 13 is formed, and a door 14 for opening and closing the freezing chamber 12 and the refrigerating chamber 13 is installed in the main body 10 of the freezing chamber 12 and the refrigerating chamber 13. The freezing chamber 12 and the refrigerating chamber 13 are provided with a multi-stage shelf 15 for storing food. An evaporator 20 is formed at the rear of the freezer compartment 12 and partitioned from the freezer compartment 12 by the front cover 21 to generate cold air, and the cold air generated above the evaporator 20 is freezer compartment 12 and the refrigerating compartment. Propeller fan (2) for forcibly blowing to 13 and the fan motor (1) for driving it are installed.

이와 같이 구성된 종래의 냉장고의 냉기 순환과정을 설명하면 다음과 같다.Referring to the cold air circulation process of the conventional refrigerator configured as described above are as follows.
냉동싸이클이 수행되어 증발기(20)에서 생성된 냉기는 프로펠러팬(2)에 의하여 흡입되어 전면커버(21)에 토출된다. 토출된 냉기는 전면커버(21)에 부딪치면서 토출구(3)를 통하여 냉동실(12)로 토출되며, 약 25%의 냉기는 덕트(27)를 통하여 냉장실(13)로 토출된다. 냉동실(12)과 냉장실(13)로 강제 송풍된 냉기는 각 실에서 열교환을 수행하여 냉동실(12)과 냉장실(13)을 빙온과 저온으로 유지시켜 냉동 또는 냉장식품을 저장보관토록 하는 것이다. 냉동실(12)과 냉장실(13)에서 열교환을 수행하여 온도가 상승된 냉기는 복귀덕트(28)를 통하여 증발기(20)로 복귀되어 재냉각된 후 강제 송풍되어 열교환을 반복 수행하는 것이다.The refrigeration cycle is performed, the cold air generated in the evaporator 20 is sucked by the propeller fan (2) and discharged to the front cover (21). The discharged cold air is discharged into the freezing chamber 12 through the discharge port 3 while hitting the front cover 21, and about 25% of the cold air is discharged into the refrigerating chamber 13 through the duct 27. The cold air forcedly blown into the freezing chamber 12 and the refrigerating chamber 13 performs heat exchange in each chamber to keep the freezing chamber 12 and the refrigerating chamber 13 at ice temperature and low temperature so as to store frozen or refrigerated food.

However, the forced air blowing hit the front panel and distributed, resulting in a noise increase of about 5dB. In addition, there is a problem that the cooling efficiency is lowered due to the rise of the cold air temperature due to the collision heat caused by the collision of cold air.

냉동싸이클이 수행되어 증발기(20)에서 냉기가 생성되면 원심팬(23)이 작동되어 냉기를 강제 송풍하게 된다. 이때 증발기(20)에서 생성된 냉기는 연통구(25)를 통하여 원심팬(23)으로 흡입되어 스크롤덕트(23)를 따라 나선형으로 분산되어 송풍된다. 송풍된 냉기중 약 75%정도는 유입안내부재(31)의 안내를 받아 냉기토출구(26)로 유입되어 냉동실(12)로 토출된다. 냉기토출구(26)로 유입되지 않은 냉기는 덕트(27)를 따라 냉장실(13)로 송풍된다. 냉동실(12)과 냉장실(13)로 송풍된 냉기는 각 실에서 열교환되어 냉동실(12)과 냉장실(13)을 빙온 또는 저온으로 만들어 냉동 또는 냉장식품을 저장하게 되는 것이다.When the refrigeration cycle is performed to produce cold air in the evaporator 20, the centrifugal fan 23 is operated to force cold air. At this time, the cold air generated in the evaporator 20 is sucked into the centrifugal fan 23 through the communication port 25 and is helically dispersed and blown along the scroll duct 23. About 75% of the blown cold air is introduced into the cold air discharge port 26 by the guide of the inflow guide member 31 and discharged into the freezing chamber 12. Cold air not introduced into the cold air outlet 26 is blown into the refrigerating chamber 13 along the duct 27. The cold air blown into the freezing chamber 12 and the refrigerating chamber 13 is heat-exchanged in each chamber to make the freezing chamber 12 and the refrigerating chamber 13 at an ice temperature or a low temperature to store frozen or refrigerated food.
이상에서 상세히 설명한 바와 같이 본 고안에 따른 냉장고는 냉기를 원심팬을 이용하여 냉기를 나선형으로 분산하여 송풍하기 때문에 냉기의 충돌소음을 저감시켜 냉기송풍시 발생되는 소음을 약 4dB정도 저감시키는 이점이 있다.As described in detail above, the refrigerator according to the present invention has the advantage of reducing the noise generated during cold air blowing by reducing the collision noise of cold air because the cold air is helically dispersed and blown using a centrifugal fan. .
또한 송풍되는 냉기의 충돌을 억제하여 충동열에 의한 냉기의 손실을 방지하여 냉각효율을 향상시키는 이점이 있다.In addition, there is an advantage of improving the cooling efficiency by preventing the impact of cold air blown to prevent the loss of cold air due to the impulse heat.
