BATTERY POWERED AIR MOVER
One feature pertains to an air mover the includes a direct current (DC) electric motor, an impeller operatively coupled to the DC motor, a battery electrically coupled to the DC motor, and a housing that includes the DC electric motor, the impeller, and the battery.
1 . An air mover comprising:
a direct current (DC) electric motor;
an impeller operatively coupled to the DC motor;
a battery electrically coupled to the DC motor; and
a housing that includes the DC electric motor, the impeller, and the battery.
2 . The air mover of claim 1 , wherein the air mover further comprises:
a control interface on a side of the air mover.
3 . The air mover of claim 2 , wherein the air mover further comprises:
an inner control housing that houses and secures the battery.
4 . The air mover of claim 3 , wherein the control interface covers the inner control housing.
5 . The air mover of claim 3 , wherein the inner control housing includes a control box that houses electrical components associated with one or more controls on the control interface.
6 . The air mover of claim 4 , wherein the inner control housing includes a slotted, perimeter grille that is configured to allow air to flow around and past the inner control housing and into an interior region of the air mover.
7 . The air mover of claim 6 , wherein the control interface includes an ON/OFF switch.
8 . The air mover of claim 7 , wherein the control interface further includes at least one of an impeller speed control and/or a battery charge meter that indicates an amount of battery charge remaining in the battery.
9 . The air mover of claim 1 , wherein the housing includes an air inlet opening on a first side of the air mover that is configured to draw air into an interior region of the air mover and an air outlet opening that is configured to blow air generated by the impeller out from the air mover.
10 . The air mover of claim 9 , wherein the DC electric motor has a nominal input voltage rating of X volts and the battery has a nominal terminal voltage of substantially X volts.
11 . The air mover of claim 10 , wherein the DC electric motor has a nominal input voltage rating of about 36 volts and the battery has a nominal terminal voltage of about 36 volts.
12 . The air mover of claim 11 , wherein the DC electric motor drives the impeller to generate at least 600 CFM of airflow at the air outlet opening.
13 . The air mover of claim 1 , wherein the housing further includes a semi-annular cavity around a cylindrical perimeter of the housing that is adapted to secure the battery, the battery being semi-annular in shape.
14 . The air mover of claim 1 , wherein the DC electric motor has a nominal input voltage rating of X volts and the battery has a nominal terminal voltage of 0.50X to 0.75X volts.
15 . The air mover of claim 1 , wherein the DC electric motor has a nominal input voltage rating of 54 volts and the battery has a nominal terminal voltage of 36 volts.
