Abstract

The present invention relates to a blower fan, whose airflow direction is changed, and an air conditioner comprising the same. According to an embodiment of the present invention, the blower fan comprises: a hub whose center is combined with a rotation shaft; a shroud which is distanced from the hub and whose center unit has a suction hole, which sucks up air; and a plurality of blades, which are placed between the hub and the shroud. The hub is formed in the shape of a straight line (Ah) inclined with the direction of the rotation shaft from the part, where the hubs longitudinal cross-section is connected to a front of the blades, to an outer circumferential end. The shroud is formed in the shape of a straight line (Ch) inclined with the direction of the rotation shaft from the part, where the shrouds longitudinal cross-section is connected to the front of the blades, to the outer circumferential end, and air sucked up by the suction hole is able to be in an inclined way discharged after flowing along an inclined straight part of the shroud and an inclined part of the hub. In addition, the inclined straight line part (Ah) of the longitudinal cross-section of the hub is longer than the inclined straight line part (Ch) of the longitudinal cross-section of the shroud, and air can flow in an inclined way upwards along the hub.

Description

송풍팬 및 이를 포함하는 공기조화기 {Mechanical fan and Air conditioner comprising the same}Technical Field [0001] The present invention relates to a blower fan and an air conditioner including the same,

본 발명은 공기의 유동 방향이 변경되는 송풍팬 및 이를 포함하는 공기조화기에 관한 것이다.BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a blowing fan in which the direction of air flow is changed and an air conditioner including the same.

공기조화기는 공기를 유동하여 냉방, 난방, 정화 또는 가습하여 실내를 쾌적한 환경으로 변화시키는 장치이다. 이러한 공기조화기는 외부의 공기를 흡입한 후 토출하기 위하여 내부에 공기를 유동하는 송풍팬이 설치된다. 공기조화기의 성능을 최대화하기 위하여 가급적 많은 공기가 유입된 후 토출되는 것이 유리하므로 송풍팬의 풍량이 높아야 한다. 그러나, 송풍팬은 풍량이 높을수록 소음과 진동 발생이 많이지는 문제점이 있다.The air conditioner is a device that changes the inside of a room into a pleasant environment by cooling, heating, purifying or humidifying by flowing air. Such an air conditioner is provided with a blowing fan for sucking outside air and then discharging the air to the outside. In order to maximize the performance of the air conditioner, it is advantageous to discharge the air after as much air as possible, so that the air flow rate of the air blowing fan must be high. However, the blowing fan has a problem that the higher the air flow rate, the more noise and vibration are generated.

뒷전(24'b-2)은 쉬라우드(24'c)와 연결되는 지점과 가까운 부분이 곡선으로 형성되되 반경반향으로 돌출되도록 볼록하게 형성되어 쉬라우드(24'c)와 뒷전(24'b-2)의 유동 간섭에 의한 와류 발생을 억제한다.The trailing edge 24'b-2 is formed so as to be curved in a portion close to the point where it is connected to the shroud 24'c and is convexly formed so as to protrude in the radial direction so that the shroud 24'c and the trailing edge 24'b- -2) due to the flow interference.

뒷전(24'b-2)은 곡선으로 형성된 부분(24'a-2a)이 직선으로 형성된 부분(24'a-2b)보다 더 많은 것이 바람직하다. 곡선으로 형성된 부분(24'a-2a)이 많을수록 와류 발생이 억제되나 블레이드(24'b)의 면적이 지나치게 넓어지는 경우 송풍모터(22)의 전력소모가 커질 수 있으므로 곡선으로 형성된 부분(24'a-2a)은 상하방향을 기준으로 뒷전(24'b-2)의 75%~85%인 것이 바람직하다.It is preferable that the trailing edge 24'b-2 is larger than the portion 24'a-2b formed with the curved portions 24'a-2a. As the number of curved portions 24'a-2a increases, the occurrence of vortex is suppressed. However, when the area of the blade 24'b is excessively wide, the power consumption of the blowing motor 22 may increase, a-2a is preferably 75% to 85% of the trailing edge 24'b-2 with respect to the vertical direction.
