Benefits of technology

[0006]The principles of the present invention provide for a fanned vent cover insert for increasing air flow from an air vent. The principles of the present invention further provide for a fanned vent cover insert for increasing air flow from an air vent without increasing the size of a blower motor and without requiring modifications to existing electrical power distribution.

Problems solved by technology

But, if the blower output splits into multiple ducts or if an air vent is a long way from a blower motor significant pressure drops can occur which can seriously reduce the air output.
However, that can involve significant additional costs for a larger blower motor as well as any additional electrical power that would be required to drive the blower motor.
Furthermore, simply increasing the blower motor output may cause air flow imbalances given that air vents close to the motor will still output most of the moving air.
Problems of multiple air ducts branches and air vents located a long way from a blower motor also occur in many existing systems.
Retrofitting such systems can be extremely difficult and costly, particularly if additional electrical power requirements are required.

Embodiment Construction

[0016]The presently disclosed subject matter now will be described more fully hereinafter with reference to the accompanying drawings in which one embodiment is shown. However, it should be understood that this invention may take many different forms and thus should not be construed as being limited to the embodiment set forth herein. In the figures like numbers refer to like elements throughout.

[0017]The present invention is described herein with reference to FIGS. 1 to 6. Specifically, the present invention is described as a fanned vent cover insert that is suitable for insertion between an air vent and an air duct exhaust. The fanned vent cover insert is for increasing air flow from an air ducting system without increasing the size of a given blower motor and without requiring modification to existing electrical power distribution.

[0018]FIG. 1 illustrates an air handling system 10 that is in accord with the principles of the present invention. The air handling system 10 includes ...

Abstract

A fanned vent cover insert, and an air handing system having such a fanned vent cover insert, for increasing air flow from an air vent. The fanned vent cover insert includes a battery and a direct current motor-generator having a rotor. A fan is attached to the rotor. A blower switch selectively connects the battery to the motor-generator so as to selectively cause the fan to move air. A battery charger is connected to the motor-generator and to the battery. The battery charger charges the battery when air moves the fan when the motor is not turning the fan.

Description

FIELD OF THE INVENTION[0001]The presently disclosed subject matter is directed towards a fanned vent cover insert for assisting air flow from an air duct into a room.BACKGROUND OF THE INVENTION[0002]Forced air heating and cooling has been successfully used for many years in many different applications. Such systems incorporate fanned blower motors that blow hot air from a furnace or cold air from an air conditioner through an air duct and out an air vent into a room. By adding numerous air duct branches to the system multiple areas can be heated and cooled from a central furnace / air conditioner.[0003]Forced air heating and cooling works particularly well when the air ducting system does not include too many duct branches and when all air vents are close to the blower motor. But, if the blower output splits into multiple ducts or if an air vent is a long way from a blower motor significant pressure drops can occur which can seriously reduce the air output.[0004]A prior art approach t...
