Abstract

A suspended ceiling fan assembly comprising: a housing having a central section in a generally dome-shaped configuration with a first axis and with an external periphery formed as a square, the periphery including a wall extending from the periphery of the dome-shaped component and, at its end, inturned ledges in a rectangular configuration, the ledges adapted to be supported upon the periphery opening; a fan supported by the center of the housing and extending therefrom, the fan having a motor with a circular cross-section about an axis of rotation coincident with the axis of the housing, the fan including a plurality of blades secured to the motor for rotation in a plane about the axis of rotation of the motor; and a plurality of louvers to spread out air forced outwardly by the rotation of the fan blades.

Claims

1. A new and improved suspended ceiling fan assembly comprising, in combination:

a housing having an upper central section in a generally dome-shaped configuration with a vertical axis and an external periphery formed as a square, the periphery including a vertical wall extending downwardly from the periphery of the central section and, at a lower end of the vertical wall, inwardly turned ledges in a rectangular configuration, the ledges supported upon a peripheral opening of a panel in a drop ceiling;

a fan supported by a center of the housing and extending downwardly therefrom, the fan having a motor with a circular cross-section about a vertical axis of rotation coincident with the axis of the housing, the fan including a plurality of blades secured to the motor for rotation in a horizontal plane about the axis of rotation of the motor;

a plurality of circular louvers positioned axially outwardly from the central section of the housing with the louvers beneath the housing to spread out air forced downwardly by the rotation of the fan blades; and

a plurality of radially extending vertically disposed planar ribs coupled between the motor and the periphery of the housing to define beneath the housing a path of travel for air from a room to enter and move to a location above the fan blades for being blown outwardly by the fan blades into the room therebeneath in an air recirculation mode.

2. A suspended fan assembly comprising:

a housing having a central section in a generally dome-shaped configuration with a first axis and with an external periphery formed as a square, the periphery including a wall extending from the periphery of the central section and, at a lower end of the wall, inwardly turned ledges in a rectangular configuration, the ledges supported upon a peripheral opening;

a fan supported by a center of the housing and extending therefrom, the fan having a motor with a circular cross-section about an axis of rotation coincident with the axis of the housing, the fan including a plurality of blades secured to the motor for rotation in a plane about the axis of rotation of the motor; and

a plurality of louvers to spread out air forced outwardly by the rotation of the fan blades.

3. The assembly as set forth in claim 2 wherein the motor is mounted about a vertical axis, the louvers are circular and further including:

a plurality of radially extending vertically disposed planar ribs coupled between the motor and the periphery of the housing to define a path of travel for air from a room to enter and move to a location above the fan blades for being blown downwardly in the fan blades in a mode of recirculation.
