Abstract

PURPOSE: To reduce the noise caused by a collision of the newly sucked air with the already-sucked air in a centrifugal fan, by arranging such that the newly sucked air is so guided by a tapered surface formed on a ring provided at the periphery of the blade at the suction side as to avoid the collision with the already-sucked air.
CONSTITUTION: A rotary axis 6 is turned by means of a fan motor 5, and a fan 7 with blades facing backward is also turned at high speed so as to such the indoor air from an inlet 2 while a heat exchanger 4 is used to exchange heat. At this time, the air to be exchanged is sucked under by the blade 11 of the fan 7 above through a bell house 9, and further guided to a fan casing 8, before being discharged from an outlet 3. Then the sucked air is guided by the inclined face 13a and led to the internal side of the blade 11 because the inclined face 13a is provided on the front side of the ring 13 installed along the external periphery located on the suction side of the blade 11. Therefore the collision between the air to be sucked and what has been inhaled in the fan casing 8 can be prevented. In addition, the air is smoothly guided to the casing 8.
