이하에서는 본 발명에 따른 제 1 실시예를 도면을 참조하여 상세히 설명한다. Hereinafter, a first embodiment according to the present invention will be described in detail with reference to the drawings.

본 실시예에서는 본 발명에 따른 팬 조립체가 공기청정기에 적용된 경우를 예로써 설명한다. In this embodiment, a case in which the fan assembly according to the present invention is applied to an air cleaner will be described as an example.

본 발명에 따른 팬 조립체가 적용된 공기청정기는 도 1에 도시되어 있는 바와 같이, 하부 측면에 공기가 흡입되는 흡입구(11)가 마련되고 상면에 공기가 토출되는 토출구(12)가 마련된 본체(10)을 구비한 것으로, 본체(10) 내에는 흡입구(11)를 덮도록 배치되어 흡입구(11)를 통해 유입되는 공기로부터 먼지 등의 이물질을 걸러 공기를 정화시키는 필터(20)와, 흡입력 및 송풍력을 발생시켜 공기가 흡입구(11)를 통해 유입되어 필터(20)에 의해 걸러진 후 토출구(12)를 통해 배출될 수 있게 하는 팬 조립체(30)가 포함되어 있다. As shown in FIG. 1, the air cleaner to which the fan assembly according to the present invention is applied, the main body 10 is provided with an inlet port 11 through which air is sucked and a discharge port 12 through which air is discharged. And a filter 20 disposed in the main body 10 to cover the suction port 11 to filter foreign substances such as dust from the air flowing through the suction port 11, and a suction force and a blowing force. A fan assembly 30 is included to generate air so that air is introduced through the inlet 11 to be filtered by the filter 20 and then discharged through the outlet 12.

팬 조립체(30)는 송풍력을 발생시켜 축방향으로 공기를 유동시키는 축류팬(31)과, 전원을 인가받아 회전력을 발생시키며 그 회전력을 회전축(33)을 통해 축류팬(31)에 전달하여 축류팬(31)을 회전시키는 구동모터(32)를 포함한다. The fan assembly 30 generates a blowing force and flows the air in the axial direction, and the axial flow fan 31 generates a rotational force by applying power, and transmits the rotational force to the axial flow fan 31 through the rotating shaft 33. It includes a drive motor 32 for rotating the axial flow fan (31).

본 실시예에서 축류팬(31)은 본체(10)의 상부에 그 축선이 상하를 향하도록 배치되어 공기를 하측에서 상측으로 유동시킬 수 있도록 되어 있으며, 그에 따라 공기는 본체(10)의 하부 측면에 마련된 흡입구(11)를 통해 본체(10) 내로 유입되었다가 상면에 마련된 토출구(12)를 통해 배출되게 된다. In this embodiment, the axial flow fan 31 is arranged on the upper portion of the main body 10 so that its axis faces upward and downward to allow air to flow from the lower side to the upper side, whereby the air is the lower side of the main body 10. It is introduced into the main body 10 through the suction port 11 provided in the discharge port 12 is provided on the upper surface.

이 때, 회전축(33)은 구동모터(32)의 양측으로 연장되며 축류팬(31)과 마찬가지로 그 축선이 상하로 길게 배치되어, 그 상단에 축류팬(31)이 설치되도록 되어 있으며, 그 하단에는 축류팬(31)의 흡입측 공간의 압력을 상승시키기 위한 보조팬(34)이 마련되어 있다. At this time, the rotary shaft 33 extends to both sides of the drive motor 32, and the axis line is vertically arranged up and down like the axial fan 31, so that the axial flow fan 31 is installed on the upper end thereof, The auxiliary fan 34 for raising the pressure of the suction side space of the axial flow fan 31 is provided.

본 실시예에서 보조팬(34)은 축방향 하측으로부터 공기를 흡입하여 그 반대측으로 경사지게 토출하는 사류팬으로 이루어진 것으로, 흡입구(11)가 마련된 본체(10)의 하부 공간으로부터 공기를 흡입하여 상측으로 경사지게 배출하여 축류팬(31)의 흡입측 공간의 압력을 높이고, 그에 따라 축류팬(31)의 흡입측 공간과 축류팬(31)의 토출측 공간의 압력차는 줄어들어 팬 조립체(30)의 송풍능력이 향상될 수 있을 뿐만 아니라 팬 조립체(30)에서 발생하는 소음이 저감될 수 있게 된다. In the present embodiment, the auxiliary fan 34 is composed of a four-flow fan which sucks air from the lower side in the axial direction and discharges it inclined to the opposite side, and sucks air from the lower space of the main body 10 provided with the suction port 11 to the upper side. By discharging at an angle, the pressure in the suction side space of the axial fan 31 is increased, and accordingly the pressure difference between the suction side space of the axial flow fan 31 and the discharge side space of the axial flow fan 31 is reduced, so that the blowing capacity of the fan assembly 30 is reduced. Not only can it be improved, but noise generated in the fan assembly 30 can be reduced.

도 2에는 축류팬(31)이 단독으로 운전될 경우의 풍량과 축류팬(31)과 함께 사류팬을 보조팬(34)으로 사용할 경우의 회전수에 따른 풍량을 실험을 통해 비교하여 도시한 그래프가 도시되어 있다. 도시되어 있는 바와 같이 동일한 회전수일 경우, 축류팬(31)과 함께 보조팬(34)을 사용할 경우 상대적으로 높은 풍량을 얻을 수 있다는 것을 확인할 수 있다. 따라서, 축류팬(31)과 함께 보조팬(34)을 사용할 경우 팬 조립체(30)의 송풍능력은 향상된다. FIG. 2 is a graph showing the amount of air flow when the axial flow fan 31 is operated alone and the amount of air flow according to the rotation speed when the drift fan 31 is used as the auxiliary fan 34 together with the axial flow fan 31. Is shown. As shown in the figure, when using the auxiliary fan 34 together with the axial fan 31, it can be seen that a relatively high air volume can be obtained. Accordingly, when the auxiliary fan 34 is used together with the axial fan 31, the blowing ability of the fan assembly 30 is improved.

또한, 도 3에는 축류팬(31)이 단독으로 운전될 경우의 풍량과 축류팬(31)과 함께 사류팬을 보조팬(34)으로 사용할 경우의 풍량에 따른 소음을 실험을 통해 비교하여 도시한 그래프가 도시되어 있다. 도시되어 있는 바와 같이 동일한 풍량을 갖는 경우 축류팬(31)과 함께 보조팬(34)을 사용할 경우 상대적으로 소음 발생이 적다는 것을 확인할 수 있다. 따라서, 축류팬(31)과 함께 보조팬(34)을 사용할 경우 팬 조립체(30)의 소음은 저감된다. In addition, FIG. 3 compares the air flow rate when the axial flow fan 31 is operated alone and the noise according to the air flow rate when the crossflow fan is used as the auxiliary fan 34 together with the axial flow fan 31. The graph is shown. As shown in the figure, it can be seen that when the auxiliary fan 34 is used together with the axial fan 31, the generation of noise is relatively low. Thus, when the auxiliary fan 34 is used together with the axial fan 31, the noise of the fan assembly 30 is reduced.

본 실시예에서는 보조팬(34)으로 사류팬을 사용했을 경우를 예로써 설명하였으나, 이에 한정하지 않고, 도 4에 본 발명의 제 2 실시예로 제시한 바와 같이 보 조팬(35)이 터보팬으로 이루어지게 할 경우에도 실질적으로 동일한 작용효과를 얻을 수 있다. In the present embodiment, a case in which a swirl fan is used as the auxiliary fan 34 is described as an example. However, the present invention is not limited thereto, and the auxiliary fan 35 is a turbo fan as shown in FIG. 4 as the second embodiment of the present invention. Even if it is made to be substantially the same effect can be obtained.

또한, 본 실시예에서는 흡입구(11)측에 필터(20)가 배치되어 있는 공기청정기를 예로써 설명하였으나 이에 한정하지 않고, 도 5에 본 발명의 제 3 실시예로 제시한 바와 같이 흡입구(11)측에 열교환기(40)를 배치하여 흡입구(11)를 통해 유입된 공기가 열교환기(40)와 열교환하며 냉각 또는 가열되게 하는 공기조화기에 사용하는 것도 가능하다. In addition, in the present embodiment, the air purifier in which the filter 20 is disposed on the inlet 11 is described as an example, but the present invention is not limited thereto. As shown in FIG. 5, the inlet 11 is shown as a third embodiment of the present invention. The heat exchanger 40 may be disposed at the side of the heat exchanger 40 to be used in an air conditioner in which air introduced through the suction port 11 exchanges heat with the heat exchanger 40 and is cooled or heated.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 팬 조립체 및 이를 갖춘 공기청정기와 공기조화기에는, 일단에 축류팬이 설치된 구동모터의 회전축 타단에 보조팬이 설치되어 있으므로, 보조팬에 의해 축류팬의 흡입측 공간의 압력이 상승하여 팬 조립체의 송풍효율이 향상될 뿐만 아니라, 팬 조립체의 구동시 발생하는 동작소음이 저감되는 작용효과가 있다.As described in detail above, in the fan assembly according to the present invention, the air cleaner and the air conditioner provided with the same, an auxiliary fan is installed at the other end of the rotary shaft of the drive motor in which the axial fan is installed at one end thereof. As the pressure of the suction side space rises, not only the blowing efficiency of the fan assembly is improved, but also the operation noise generated when the fan assembly is driven is reduced.
