Abstract

A fan assembly includes a fan housing including a shroud that at least partially defines an airflow chamber, a battery receptacle supported on the shroud, a first grille positioned adjacent a first end of the airflow chamber, a fan supported within the airflow chamber and rotatably coupled to one of the first grille or the shroud, and a motor supported on the other of the first grille or the shroud. The motor is operable to drive rotation of the fan and thereby generate airflow through the airflow chamber. The fan assembly further includes a base coupled to the fan housing. The base is operable to support the fan housing in multiple configurations to direct the airflow in multiple directions.

First claim

What is claimed is:

1. A fan assembly comprising:
a fan housing including a shroud that at least partially defines an airflow chamber, the shroud including an outer wall, vanes extending inwardly from the outer wall, and a mount coupled to the vanes;
a battery receptacle positioned on the shroud, the battery receptacle configured to receive a removable battery pack to provide power to the fan assembly;
a first grille coupled to a first side of the shroud, the first grille positioned adjacent an end of the airflow chamber;
a fan supported within the airflow chamber;
a motor supported by the mount, the motor operable to drive rotation of the fan and thereby generate airflow through the airflow chamber; and
a base rotatably coupled to the fan housing about an axis, the base operable to support the fan housing in multiple configurations to direct the airflow in multiple directions; and
an AC power unit supported by the fan housing and configured to power to the motor;
wherein the AC power unit and the battery receptacle are disposed on opposite sides of the axis.

2. The fan assembly of claim 1 , wherein a second grille is coupled to a second side of the shroud that is opposite the first side, and wherein the fan and the motor are fully positioned between the opposite ends of the airflow chamber.

3. The fan assembly of claim 1 , wherein wiring electrically communicating the battery receptacle to the motor is routed through at least one of the vanes.

4. The fan assembly of claim 1 , wherein the AC power unit includes terminals configured to receive a power cable.

5. The fan assembly of claim 1 , wherein the battery receptacle and the AC power unit are both supported on a circumferential wall of the shroud.

6. The fan assembly of claim 1 , wherein the AC power unit is coupled to the battery receptacle such that the removable battery pack is configured to receive charging power communicated from the AC power unit to the battery receptacle.

7. The fan assembly of claim 6 , wherein the AC power unit and the battery receptacle are supported on diametrically opposing sides of the fan housing.

8. The fan assembly of claim 6 , wherein the AC power unit is configured to simultaneously power the motor and charge the removable battery pack.

9. A fan assembly comprising:
a fan housing including a shroud that at least partially defines an airflow chamber;
a battery receptacle supported on the shroud, the battery receptacle configured to receive a removable battery pack to provide power to the fan assembly;
a handle extending from the battery receptacle to the shroud;
a selector disposed on the battery receptacle configured to operatively control the fan;
a first grille positioned adjacent a first end of the airflow chamber;
a motor supported by the shroud, the motor operable to drive rotation of the fan and thereby generate airflow through the airflow chamber;
a fan supported within the airflow chamber and rotatably coupled to the motor;
a base coupled to the fan housing, the base operable to support the fan housing in multiple configurations to direct the airflow in multiple directions.
