A ceiling fan includes a suspending unit and a ceiling fan body. The ceiling fan body includes a shaft; a motor; a plurality of blades; an upper body cover having a first opening, at a central part, for passing the shaft therethrough, and a second opening outside the first opening; and a lower body cover. The upper body cover rotates with the blades and has a first wall standing vertically between the first opening and the second opening.
1. A ceiling fan comprising:
a suspending unit fixed to a ceiling; and
a ceiling fan body suspended by the suspending unit, the ceiling fan body including:
a shaft configured to be suspended by the suspending unit;
a motor fixed at a bottom of the shaft;
a plurality of blades attached to the motor;
an upper body cover disposed on an upper surface of the motor; and
a lower body cover covering the motor,
the upper body cover having a first opening at a central part for passing the shaft therethrough, and a second opening outside the first opening,
wherein the upper body cover rotates with the blades and has a first wall protruding vertically from the upper body cover between the first opening and the second opening, the first wall being a cylindrical plate and having a top edge,
wherein the upper body cover has a first inclined surface inclining downward in an outward direction between the first opening and the first wall.
2. The ceiling fan of claim 1 , wherein
the first wall is adjacent to the second opening.
3. The ceiling fan of claim 1 , wherein
the upper body cover further has a second inclined surface outside the first wall, the second inclined surface inclining downward in the outward direction from the first wall; and
the second opening is formed in the second inclined surface.
4. The ceiling fan of claim 1 , wherein
the upper body cover further includes a second wall standing around the shaft along a periphery of the first opening.
5. The ceiling fan of claim 1 , further comprising:
an outer cover covering a periphery of the suspending unit and the upper body cover.
6. The ceiling fan of claim 1 , wherein
the first wall includes a groove communicating between the first inclined surface and an outside of the second opening by way of a guide unit located between the second opening and another of the second opening.
7. A ceiling fan body for a ceiling fan, the ceiling fan body comprising:
an upper body cover; and
a lower body cover,
wherein the upper body cover includes a central hole configured to receive a shaft portion which is mechanically engaged with a motor, the motor including a stator and a rotor rotating around the stator, the upper body cover disposed on an upper surface of the rotor,
wherein the upper body cover includes a plurality of slits disposed radially in an outer periphery of the central hole for radiating heat, and
wherein the upper body cover includes a wall portion disposed between the plurality of slits and the central hole, the wall portion including a plurality of arc-shaped portions and guide unit portions, the wall portion being a cylindrical plate protruding vertically from the upper body cover and having a top edge,
the upper body cover further includes a first inclined surface inclining downward in an outward direction from the central hole to the wall portion, and a plurality of grooves, each of the plurality of grooves located between adjacent guide unit portions and where the wall portion is not formed.
8. The ceiling fan body of claim 7 , wherein the upper body cover further includes a second wall portion disposed along a periphery of the central hole.
9. The ceiling fan of claim 4 , wherein
the upper body cover has a first inclined surface inclining downward in an outward direction from the first opening to the first wall.
10. A ceiling fan body for a ceiling fan, the ceiling fan body comprising:
an upper body cover; and
a lower body cover,
wherein the upper body cover includes a central hole configured to receive a shaft portion which is mechanically engaged with a motor, the motor including a stator and a rotor rotating around the stator, the upper body cover disposed on an upper surface of the rotor,
wherein the upper body cover includes a plurality of slits disposed radially in an outer periphery of the central hole for radiating heat, and
wherein the upper body cover includes a wall portion disposed between the plurality of slits and the central hole, the wall portion including a plurality of arc-shaped portions and guide unit portions, the wall portion being a cylindrical plate protruding vertically from the upper body cover and has a top edge,
the upper body cover further includes a first inclined surface inclining downward in an outward direction from the central hole to the wall portion and a second surface outside the wall portion, the plurality of slits formed in the second surface.
