摘要： Provided is a turbofan producing reduced noise and easily manufactured. A coupling portion 7 between a blade main portion 5 and a blade cover 6 is formed in a surface region (pressure surface 12) parallel to a direction of air flowing over the pressure surface 12 of each blade 2. With this configuration, the air sucked from a direction of a rotation axis of a turbofan 20 is less liable to enter a gap of the coupling portion 7 of the blade 2, thereby being capable of reducing noise. Further, noise is reduced so that high-precision dimensional control of the gap of the coupling portion 7 of the blade 2 is not required. Consequently, dimensional control at the time of manufacture is facilitated to thereby facilitate manufacture.
摘要翻译：提供了降低噪音并且容易制造的涡轮风扇。在叶片主体部5与叶片罩6之间的连结部7形成在与在各叶片2的压力面12上流动的空气的流动方向平行的面区域（压力面12）上。由此，吸入的空气从涡轮风扇20的旋转轴线的方向不易进入叶片2的连结部7的间隙，能够降低噪音。此外，降低了噪音，因此不需要对叶片2的连结部7的间隙进行高精度的尺寸控制。因此，制造时的尺寸控制变得容易，制造容易。

摘要： An indoor unit (1) includes a housing (2), a centrifugal fan (3), a heat exchanger (4), and a partition plate (5). The centrifugal fan (3) is contained in the housing (2), has a rotational axis, and is configured to rotate about the rotational axis. The heat exchanger (4) is arranged to surround at least three quarters of an outer circumferential periphery of the centrifugal fan (3), and has a first end (41) located upstream in a rotational direction of the centrifugal fan (3), and a second end (42) located downstream in the rotational direction of the centrifugal fan (3) and spaced from the first end (41). The partition plate (5) has a protruding portion (51) protruding toward the centrifugal fan (3) from the first end (41) and the second end (42) of the heat exchanger (4). An apex (TP) of the protruding portion (51) of the partition plate (5) is located closer to the first end (41) than to the second end (42).
