Floor Vent Booster Fan
The invention consists of a vent booster fan, comprising: a) a vent housing, forming a vent which is operable for insertion into a ventilation duct; and defining a vent surface through which air flows from the duct; b) a fan assembly located within the vent housing, containing a fan operative to force air through the vent, the fan assembly located within the vent housing so as to be located substantially within the duct; c) an air deflector covering a portion of the vent surface sufficient to alter airflow from the vent.
1 . A booster fan, comprising:
a) a vent housing, forming a vent which is operable for insertion into a ventilation duct; and defining a vent surface through which air flows from the ventilation duct;
b) a fan assembly located within the vent housing, containing a fan operative to force air through the vent, the fan assembly located within the vent housing so as to be located substantially within the ventilation duct;
c) an air deflector grille covering a portion of the vent surface, said air deflector grille being of sufficient size to alter airflow from the vent.
2 . The booster fan of claim 1 , further comprising:
d) an adjustable shield covering a portion of the air deflector grille to enable adjustment of airflow direction from the vent.
3 . The booster fan of claim 1 , further comprising a temperature control element, the temperature control element being one of: a heating element, a cooling element, and a combination thereof, and the temperature control element being operative to heat and cool, respectively, air flowing through the booster fan.
4 . The booster fan of claim 3 , wherein the temperature control element is mounted within the vent housing.
5 . The booster fan of claim 3 , wherein the temperature control element is mounted within the fan assembly.
6 . The booster fan of claim 2 , further comprising a temperature control element, the temperature control element being one of: a heating element, a cooling element, and a combination thereof, and the temperature control element being operative to heat and cool, respectively, air flowing through the booster fan.
7 . The booster fan of claim 6 , wherein the temperature control element is mounted within the vent housing.
8 . The booster fan of claim 6 , wherein the temperature control element is mounted within the fan assembly.
9 . The booster fan of claim 1 , wherein the booster fan is powered by an external power source and the vent includes a power cable to couple the booster fan to the external power source.
10 . The booster fan of claim 1 , wherein the booster fan is a single ‘wind wheel’ style rotary fan.
11 . The booster fan of claim 1 , further including a switch located on the vent housing, exterior to the ventilation duct, to enable activation and deactivation of the booster fan and an indicator light located on the vent housing to signal operation of the booster fan.
12 . The booster fan of a claim 1 , further including one or more air purification elements and air flow monitoring elements.
13 . The booster fan of claim 12 , wherein the air purification elements include one or more of: an air filter, a carbon filter, an ionizer and a dehumidifier.
14 . The booster fan of claim 12 , wherein the air flow monitoring elements include one or more air flow sensors.
15 . The booster fan of a claim 3 , further including one or more air purification elements and air flow monitoring elements.
16 . The booster fan of a claim 6 , further including one or more air purification elements and air flow monitoring elements.
17 . The booster fan of claim 3 , wherein the booster fan is powered by an external power source and the vent includes a power cable to couple the booster fan to the external power source.
18 . The booster fan of claim 6 , wherein the booster fan is powered by an external power source and the vent includes a power cable to couple the booster fan to the external power source.
19 . The booster fan of claim 9 , further including a switch located on the vent housing, exterior to the ventilation duct, to enable activation and deactivation of the booster fan and an indicator light located on the vent housing to signal operation of the booster fan.
20 . The booster fan of claim 17 , further including a switch located on the vent housing, exterior to the ventilation duct, to enable activation and deactivation of the booster fan and an indicator light located on the vent housing to signal operation of the booster fan.
