PURPOSE:To obtain a ventilating fan, having a high static pressure and capable of cooling a motor for the fan, by a method wherein a plurality of holes are provided on a partitioning plate, provided immediately above a blade, at positions corresponding to the outside and inside of the circumference of the blade. CONSTITUTION:The embedded ceiling type ventilating fan 1 is equipped with the motor 3, to which the blade 2 is secured, and the partitioning plate 4, partitioning the blade 2 and the motor 3, at the inside thereof while a plurality of holes 5 are provided on the partitioning plate 4 at the positions corresponding to the inside and outside of the circumference of the blade. Indoor air is sucked into the embedded ceiling type fan 1 and is discharged to the outside of a room. In this case, the partitioning plate 4 is located immediately above the blade 2 and whereby the embedded ceiling type ventilating fan having a static pressure is obtained and air flows in the fan to deprive the heat of the heated motor and generate a cooling effect since the pressure difference is generated between the holes at the positions corresponding to the inside of circumference of the blade and the holes at the positions corresponding to the outside of the same due to the provision of the partitioning plate. |
