Description

  The present invention relates to a ceiling fan that is installed on a ceiling and is used for reducing the temperature of the sensible temperature caused by direct wind or circulating indoor air.

  Conventionally, this type of ceiling fan is known to be fixed to a rotating body that is rotated by an electric motor via a connecting member that supports one end of a long blade blade (see, for example, Patent Document 1).

  Hereinafter, the ceiling fan will be described with reference to FIG.

  As shown in FIG. 9, the entire structure of the ceiling fan 101 includes a canopy (upper cover) 102, an intermediate cover 103, an outer rotating body 104 and a lower cover 105 of an electric motor, and a moving blade 107 attached to a holder 106 of the outer rotating body 104. The simple mounting bracket 108 inside the canopy 102 is screwed to the ceiling 109 and the ceiling fan 101 is suspended.

  In the above configuration, the moving blade 107 is attached at a predetermined angle in the radial direction around the rotation axis. When the moving blade 107 is rotated by the electric motor, the rotating blade 107 is not rotated in the positive direction due to the boosting action of the moving blade 107. Air passing between the ceiling 109 and the moving blade 107 from the outer periphery of the moving blade 107 is blown downward. Further, when the moving blade 107 is rotated in the reverse direction, the air is blown toward the ceiling.
