The present invention relates to a cold air circulation device of a refrigerator, and more particularly, to an apparatus for improving the cooling rate in a refrigerator by inducing a flow of cold air circulated to a refrigerating compartment and a freezing compartment to be fast.

일반적으로, 냉장고는 내부에 냉동 사이클의 구성요소가 설치되어 이로부터 발생되는 냉기를 저장실로 공급하여 각종 식품의 신선도가 장기간 유지될 수 있도록 한 가전제품이다. In general, a refrigerator is a home appliance that is provided with components of a refrigeration cycle therein to supply cold air generated therefrom to a storage compartment so that freshness of various foods can be maintained for a long time.

이러한 종래의 냉장고는 일례(대한민국 실용신안공개 제1999-00568호)로 도 1에 도시된 바와 같이 내부에 음식물이 저장되는 저장실(110)이 구비된 본체(100)가 마련되고, 이 저장실(110)은 전면부가 개구되게 마련된다. 그리고 냉동실과 냉장실의 후면 벽체에는 냉기를 생성하는 증발기(120)가 설치되며, 증발기의 상측에는 냉동실 및 냉장실의 냉기를 강제로 순환시키는 순환 팬(130)이 설치된다.Such a conventional refrigerator is provided as an example (Korean Utility Model Publication No. 1999-00568), which is provided with a main body 100 having a storage compartment 110 for storing food therein, as shown in FIG. 1, and the storage compartment 110. ) Is provided to open the front portion. And an evaporator 120 for generating cold air is installed on the rear wall of the freezer compartment and the refrigerating compartment, and a circulation fan 130 for forcibly circulating cold air of the freezer compartment and the refrigerating compartment is installed above the evaporator.

한편, 상기 순환 팬(130)의 전면부에 냉기의 압력을 분산시키는 압력분산부(140)가 마련되고, 이 압력분산부(140)는 순환 팬(130)에서 분출되는 냉기의 압력에너지가 용이하게 분산될 수 있도록 순환 팬(130)과 마주보는 볼록면으로 구성되며, 이 볼록면의 직경은 대체로 순환 팬(130)의 직경과 유사하게 형성된다. 또한 상기 압력분산부(140)는 도 2에 도시된 바와 같이 압력분산효과가 더욱 높아질 수 있도록 볼록면의 표면에서 내곡되게 형성되어, 마치 골프공의 표면에 형성된 것과 유사하게 다수의 오목부(141)가 형성되며, 이 오목부(141)는 볼록면의 표면에서 분산되는 유체의 흐름을 교란시킴으로써 압력분산효과를 더욱 높여주게 된다. On the other hand, the pressure distribution unit 140 for dispersing the pressure of the cold air is provided on the front surface of the circulation fan 130, the pressure distribution unit 140 is easy to the pressure energy of the cold air ejected from the circulation fan 130 It is composed of a convex surface facing the circulation fan 130 so that it can be dispersed, the diameter of the convex surface is formed to be substantially similar to the diameter of the circulation fan 130. In addition, the pressure distribution unit 140 is formed to be curved at the surface of the convex surface so that the pressure dispersion effect can be further increased, as shown in Figure 2, a plurality of concave portions similar to that formed on the surface of the golf ball ) Is formed, the concave portion 141 further enhances the pressure dispersion effect by disturbing the flow of the fluid dispersed on the surface of the convex surface.

그러나, 상기와 같은 종래 구조는 소음 저감면에서는 유리하지만, 유체 흐름 에 있어서 직진성을 막게 되기 때문에 고내 냉각 속도는 오히려 느리게 되는 문제점이 있었다. However, such a conventional structure is advantageous in terms of noise reduction, but has a problem in that the cooling speed in the air is rather slow because it prevents straightness in the fluid flow.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 창안한 것으로서, 유체의 유동방향이 급격하게 전환되지 않고 순환되는 냉기의 흐름이 빨라지도록 다공형유도장치를 통해 유도하여 고내 냉각 속도를 개선하는 구조를 갖는 장치를 제공하는데 그 목적이 있다. Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and improves the cooling rate in the high speed by guiding through the porous induction apparatus so that the flow of cold air is circulated without rapidly changing the flow direction of the fluid It is an object of the present invention to provide a device having a structure.

이와 같은 목적을 달성하기 위한 본 발명 냉장고의 냉기 순환장치는, 본체의 내부에 형성되는 저장실의 공기가 냉각되도록 냉기를 분출하는 순환 팬, 상기 순환 팬에서 분출되는 냉기를 저장실 쪽으로 안내하는 냉기 안내덕트, 순환 팬의 전면부에 위치하여 상기 순환 팬의 구동에 의해 분출되는 냉기의 흐름에 직진성을 부여하여 상기 냉기 안내덕트 방향으로 빠르게 유도하는 다공형 유도부 및 상기 다공형유도부를 통해 배출되는 냉기를 빠르게 저장실로 유도되도록 촉진하는 유도촉진부재를 포함 것을 특징으로 한다.In order to achieve the above object, a cold air circulation device of a refrigerator according to the present invention includes a circulation fan for ejecting cold air to cool air in a storage compartment formed inside the main body, and a cold air guide duct for guiding the cold air ejected from the circulation fan to the storage compartment. Located in the front part of the circulation fan to give a straightness to the flow of cold air blown out by the driving of the circulation fan to guide quickly in the direction of the cold air guide duct and the cold air discharged through the porous induction part It characterized in that it comprises an induction promoting member for promoting the guide to the storage compartment.

이하, 본 발명의 실시예에 따른 구성을 첨부한 도면을 참조하여 설명하면 다음과 같다. Hereinafter, a configuration according to an embodiment of the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명의 실시예에 따른 냉기 순환장치의 구성을 간략하게 보인 부분 단면도로서, 이에 도시한 바와 같이 냉기를 생성하는 증발기(120); 본체(100)의 내부에 형성되는 저장실(110)의 공기가 냉각되도록 상기 증발기(120)에서 생성된 냉기를 분출하는 순환 팬(130); 상기 순환 팬(130)에서 분출되는 냉기를 저장실(110) 쪽으로 안내하는 냉기 안내덕트(200); 및 순환 팬(130)의 전면부에 위치하여 상기 순환 팬(130)의 구동에 의해 분출되는 냉기의 흐름에 직진성을 부여하여 상기 냉기 안내덕트(200) 방향으로 빠르게 유도하는 다공형유도부(300)를 포함하여 구성한다. 3 is a partial cross-sectional view schematically showing the configuration of a cold air circulation system according to an embodiment of the present invention, as shown in the evaporator 120 for generating cold air; A circulation fan 130 for ejecting cold air generated by the evaporator 120 to cool the air in the storage compartment 110 formed in the main body 100; A cold air guide duct 200 for guiding the cold air ejected from the circulation fan 130 toward the storage compartment 110; And a porous induction part 300 positioned at a front portion of the circulation fan 130 to impart straightness to the flow of cold air ejected by the driving of the circulation fan 130, thereby rapidly inducing toward the cold air guide duct 200. Consists of including.

상기 다공형유도부(300)에는 직진성을 갖도록 다수개의 홀(hole, 310)이 형성되고, 이 다수개의 홀(310)은 상기 다공형유도부(300)에 균일하게 분포된다. A plurality of holes 310 are formed in the porous induction part 300 to have straightness, and the plurality of holes 310 are uniformly distributed in the porous induction part 300.

또한, 상기 냉기 안내덕트(200)는 상기 다공형유도부(300)를 통해 배출되는 냉기를 빠르게 저장실(110)로 유도되도록 촉진하는 유도촉진부재(210)를 포함하고 있으며, 상기 유도촉진부재(210)는 상기 다공형유도부(300) 출구쪽의 냉기 안내덕트(200) 벽면 구석에 경사지게 형성된 판으로 구성한다. In addition, the cold air guide duct 200 includes an induction promoting member 210 to promote the cold air discharged through the porous guide portion 300 to the storage compartment 110, the induction promoting member 210 ) Is composed of a plate formed to be inclined in the corner of the cold air guide duct 200 wall side of the porous guide portion 300 exit.

이와 같이 구성한, 본 발명의 실시예에 따른 순환 동작 과정을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings, a cyclic operation process according to an embodiment of the present invention configured as follows.

상기 증발기(120)에서 열교환이 된 냉기는 상기 순환 팬(130)의 구동에 의해 냉기 안내덕트(200)를 따라 흐르게 되고, 저장실(110)을 통해 다시 상기 증발기(120)로 유입됨으로써 냉기의 순환이 이루어지게 된다. The cold air that has undergone heat exchange in the evaporator 120 flows along the cold air guide duct 200 by the driving of the circulation fan 130, and flows back into the evaporator 120 through the storage chamber 110, thereby circulating the cold air. This is done.

이때, 상기 순환 팬(130)에서 분출되는 냉기는 도 4에 도시한 바와 같이 전면에 설치된 다공형유도부(300)의 홀(310)을 통과하게 되고, 이때 냉기가 흐트러짐 이 없이 홀(310)을 통과하므로, 다공형유도부(300)의 끝단(V0)에서는 속도가 최저이지만 중앙부에서는 최고속도(Vmax)가 유지된다.At this time, the cold air ejected from the circulation fan 130 passes through the hole 310 of the porous induction part 300 installed at the front side, as shown in FIG. Since passing through, the speed is the lowest at the end (V 0 ) of the porous induction part 300, but the maximum speed (V max ) is maintained in the center.

상기 홀(310)을 통과한 냉기는 냉기 안내덕트(200)를 따라 흐르다 경사진 유도촉진부재(210)에 의해 유체의 유동방향이 자연스럽게 전환되어 빠른 속도로 상기 저장실(110) 내로 이동을 한다. The cold air passing through the hole 310 flows along the cold air guide duct 200, and the flow direction of the fluid is naturally changed by the inclined induction promoting member 210 to move into the storage chamber 110 at a high speed.

따라서, 냉기의 순환 속도를 빠르게 함으로써, 저장실(110)을 냉각시키는 속도도 증가하게 된다.Therefore, by increasing the circulation speed of the cold air, the speed of cooling the storage compartment 110 is also increased.

이상에서 설명한 바와 같이 본 발명 냉장고의 냉기 순환장치는, 유체가 냉기 안내덕트의 벽면에 충돌이 없이 유동방향이 자연스럽게 이루어지도록 하고, 순환되는 냉기의 흐름이 빨라지도록 유도함으로써, 고내 냉각 속도를 개선하고, 냉기를 흐트러짐을 최소화하여 고내를 냉각시킴으로써 냉장성능도 개선되는 등의 효과가 있다. As described above, the cold air circulation system of the refrigerator of the present invention improves the cooling rate in the refrigerator by causing the fluid to flow naturally without collision with the wall surface of the cold air duct and inducing the flow of cold air to be circulated faster. In addition, the cooling performance is also improved by cooling the inside of the refrigerator by minimizing the disturbance of the cold air.
