미설명 부호 70은 압축기이고, 41은 모터 하우징이다.Reference numeral 70 is a compressor, and 41 is a motor housing.

상기한 바와 같은 냉장고의 작동은 다음과 같다.The operation of the refrigerator as described above is as follows.

먼저 전원이 인가되면 냉동사이클장치가 운전됨과 동시에 상기 모터(40)의 구동에 의해 축류팬(30)이 회전하게 되며 상기 냉동사이클장치의 운전에 의해 그 냉동사이클장치를 구성하는 상기 열교환기(20), 즉 증발기에서 외부의 열을 흡수함에 의해 냉기를 형성하게 되고 상기 축류팬(30)의 회전에 의한 압력 차에 의해 상기 열교환기(20)에서 형성되는 냉기의 유동을 발생시키게 된다.First, when power is applied, the refrigeration cycle apparatus is operated, and at the same time, the axial fan 30 is rotated by the driving of the motor 40, and the heat exchanger 20 constituting the refrigeration cycle apparatus is operated by the operation of the refrigeration cycle apparatus. In other words, by forming the cold air by absorbing the external heat from the evaporator, the flow of cold air formed in the heat exchanger 20 is generated by the pressure difference caused by the rotation of the axial fan 30.

상기 축류팬(30)의 회전에 의해 발생되는 냉기 유동의 대부분은 그릴의 유입공(13)들을 통해 냉동실(F)로 유입되고 그 냉동실(F)로 유입된 냉기 유동은 냉동실(F) 내부를 순환한 다음 상대적으로 온도가 상승한 상태에서 그 그릴의 유출공(14)을 통해 상기 열교환기(20)가 위치하는 열교환실(E)로 유입되며 그 열교환실(E)로 유입된 상대적으로 가열된 공기는 그 열교환실(E)에 장착된 열교환기(20)를 거치면서 열교환되어 상기 축류팬(30)을 통해 다시 냉동실(F)로 유입되는 순환과정을 반복하게 되면서 냉동실(F)을 설정된 온도 상태로 유지시키게 된다.Most of the cold air flow generated by the rotation of the axial fan 30 is introduced into the freezer compartment F through the inlet 13 of the grille, and the cold air flow introduced into the freezer compartment F is transferred into the freezer compartment F. After circulating, the heat is introduced into the heat exchange chamber E in which the heat exchanger 20 is located through the outlet hole 14 of the grill, and the heat is relatively heated. The air is heat-exchanged while passing through the heat exchanger 20 mounted in the heat exchange chamber E, and the temperature is set in the freezer compartment F while repeating a circulation process introduced into the freezing compartment F again through the axial flow fan 30. Will be kept in a state.

그리고 상기 축류팬(30)의 회전에 의해 발생되는 냉기 유동의 일부는 분배 공간(D)과 연통된 유입 유로(15)를 통해 상기 냉장실(R)로 유입되고 그 냉장실(R) 로 유입되는 냉기 유동은 그 냉장실(R) 내부를 순환한 다음 상대적으로 온도가 상승한 상태에서 상기 유출 유로(17)를 통해 열교환기(20)가 장착된 열교환실(E)로 유입되며 그 열교환실(E)로 유입된 상대적으로 가열된 공기는 그 열교환실(E)에 장착된 열교환기(20)를 거치면서 열교환되어 상기 축류팬(30)을 통해 다시 냉장실(R)로 유입되는 순환과정을 반복하게 되면서 냉장실(R)을 설정된 온도 상태로 유지시키게 된다.Part of the cold air flow generated by the rotation of the axial fan 30 flows into the refrigerating chamber R through the inflow passage 15 communicating with the distribution space D, and is introduced into the refrigerating chamber R. The flow circulates inside the refrigerating chamber R, and then flows into the heat exchange chamber E equipped with the heat exchanger 20 through the outlet flow path 17 in a state where the temperature rises relatively, and into the heat exchange chamber E. The introduced relatively heated air is heat-exchanged while passing through the heat exchanger 20 mounted in the heat exchange chamber E, and the circulation process is repeated to flow back into the refrigerating chamber R through the axial fan 30. It keeps (R) at the set temperature.

그러나, 종래의 이러한 축류팬(30)은 전방 직선방향으로만 풍량이 발생되어 냉장실에 효과적으로 균일하게 냉기를 순환시킬 수 없는 문제점이 있다. 또한, 냉기가 벽면에서 마찰 후 축류팬(30)으로 역풍으로 가해질 경우 소음 이 발생하고 유동이 손실되는 문제점이 있다.However, the conventional axial flow fan 30 has a problem that the air volume is generated only in the front straight direction so that the cold air cannot be effectively and uniformly circulated in the refrigerating chamber. In addition, when cold air is applied to the axial fan 30 by backwind after friction on the wall, noise is generated and flow is lost.

이러한 축(110)은 축부(100)의 내벽에서 후방으로 돌출된 돌출부(120)의 중심부에 배치되며, 돌출부(120)는 측면이 경사면(121)으로 형성된다.The shaft 110 is disposed at the center of the protrusion 120 protruding rearward from the inner wall of the shaft portion 100, the protrusion 120 is formed with an inclined surface 121 side.

날개부(200)는 축부(100)의 외주면에 원주방향을 따라 7개가 배치된다.Seven wing portions 200 are disposed along the circumferential direction on the outer circumferential surface of the shaft portion 100.

날개부(200)는 축부(100)의 측면에 경사지도록 배치되며, 방사상으로 배치되도록 설치된다.The wing 200 is disposed to be inclined to the side of the shaft portion 100, it is installed to be disposed radially.

날개부(200)는 날개부(200)의 길이방향을 따라 전면(202)이 볼록하도록 굴곡지게 형성된다. 또한, 상기 굴곡된 부분은 앞날(205)보다 뒷날(204)에 더 근접하도록 편중되게 형성된다.The wing portion 200 is formed to be curved so that the front surface 202 is convex along the longitudinal direction of the wing portion 200. In addition, the curved portion is formed to be biased closer to the rear blade 204 than the front blade 205.

나아가, 날개부(200) 외측면에는 리브(210, 220)가 돌출되어 형성된다.Furthermore, ribs 210 and 220 protrude from the outer surface of the wing 200.

자세하게는, 날개부(200) 전면(202)은 밋밋한 면으로 구비되고, 후면(201)은 리브(210, 220)가 돌출되어 형성된다.In detail, the front surface 202 of the wing 200 is provided with a flat surface, and the rear surface 201 is formed by protruding ribs 210 and 220.

이와 같이 리브(210, 220)는 날개부(200)의 후면(201)에 형성되어, 전방(A) 및 측면(B)으로 풍량을 효과적으로 공급할 수 있다.As described above, the ribs 210 and 220 may be formed on the rear surface 201 of the wing 200 to effectively supply the air volume to the front A and the side B.

리브(210, 220)는 두개 이상 다수개가 구비되며, 본 실시예에서는 하나의 날개부(200)에 3개가 서로 이격되도록 구비된다.Two or more ribs 210 and 220 are provided. In the present embodiment, three ribs 210 and 220 are provided to be spaced apart from each other.

리브(210, 220)는 중심이 축부(100)의 외측에 배치되는 원호형상으로 형성된다. 하나의 날개부(200)에 있는 3개의 리브(210, 220)는 동심원상에 배치된다. 따라서, 축부(100)에 근접한 리브(210, 220)일수록 전체 길이는 작도록 형성된다.The ribs 210 and 220 are formed in an arc shape in which a center thereof is disposed outside the shaft portion 100. Three ribs 210 and 220 in one wing 200 are arranged in concentric circles. Therefore, the ribs 210 and 220 closer to the shaft portion 100 are formed to have a smaller overall length.

바람직하게는, 상기 리브(210, 220)는 후방으로 향할수록 상기 축부(100)로부터 멀어지도록 형성된다. 즉, 원호형상의 리브(210, 220)의 중심이 뒷날(204) 외측 끝단보다 앞날(205)의 외측끝단에 근접하도록 리브(210, 220)는 형성된다.Preferably, the ribs 210 and 220 are formed to be farther from the shaft portion 100 toward the rear side. That is, the ribs 210 and 220 are formed such that the centers of the arc-shaped ribs 210 and 220 are closer to the outer ends of the front blades 205 than the outer ends of the rear blades 204.

또한, 하나의 날개부(200)에 형성되는 3개의 리브(210, 220) 중에서 축부(100)에 가장 근접한 리브(210)는 일측이 축부(100)에 연결되고 타측은 날개부(200)에 연결되어, 상기 리브(210)는 날개부(200)가 상기 축부(100)에 더욱 견고하게 연결되도록 하여 송풍팬의 내구성을 향상시킬 수 있다.In addition, one of the ribs 210 closest to the shaft portion 100 among the three ribs 210 and 220 formed in one wing portion 200 is connected to the shaft portion 100 and the other side to the wing portion 200. Is connected, the rib 210 can be more firmly connected to the wing portion 200 to the shaft portion 100 can improve the durability of the blowing fan.

또한, 축부(100)에 가장 근접한 리브(210)는 송풍팬의 회전 반대방향으로 볼록하도록 굴곡진 판형상으로 형성된다.In addition, the rib 210 closest to the shaft portion 100 is formed in a curved plate shape to be convex in the direction opposite to the rotation of the blowing fan.

축부(100)에 가장 근접한 리브(210)를 제외한 나머지 리브(220)는 단면이 반원형상인 띠형상으로 형성되어 공기저항을 최소화시킬 수 있다.Except for the rib 210 closest to the shaft portion 100, the remaining ribs 220 may be formed in a band shape having a semicircular cross section to minimize air resistance.

이와 같은 송풍팬이 냉장고의 저장고에 설치되면, 냉각장치에 의해 생성되는 냉기를 저장실 내부로 송풍시키게 된다. 모터를 통해 송풍팬을 회전시키게 되면, 도 5에 도시된 바와 같이, 송풍팬의 전방(A) 직선방향으로 풍량이 공급되게 되고, 동시에 직선 방향으로 발생된 풍량이 리브(210, 220)에 의해 바람의 방향이 변경되어 측면(B)인 방사상방향으로 풍량이 공급되게 된다. 이로 인해 저장실 모든 곳에 고르게 냉기가 송풍될 수 있는 이점이 있다. 또한, 상기 송풍팬의 전방에 배치되는 벽에 부딪혀 역풍(C)으로 상기 송풍팬에 가해지더라도 리브(210, 220)에 의해 역풍(C)이 가이드되어 공기저항이 줄어들게 된다. 따라서, 소음이 감소되고 유동손실도 줄일 수 있다.When such a blowing fan is installed in the storage of the refrigerator, the cold air generated by the cooling device is blown into the storage compartment. When the blowing fan is rotated through the motor, as illustrated in FIG. 5, the air volume is supplied in a straight line direction A of the blowing fan, and at the same time, the air volume generated in the linear direction is driven by the ribs 210 and 220. The direction of the wind is changed so that the air volume is supplied in the radial direction of the side (B). This has the advantage that the cold air can be evenly blown everywhere in the storage compartment. In addition, even when hit against a wall disposed in front of the blower fan and applied to the blower fan with a reverse wind (C), the reverse wind (C) is guided by the ribs 210 and 220 to reduce the air resistance. Therefore, noise can be reduced and flow loss can be reduced.
