Systems for delivering conditioned air to personal breathing zones

Abstract

A system to significantly improve the air quality in a personal breathing environment. The system includes a blower unit that produces a conditioned air flow, a delivery system that delivers air provided by the blower unit to a person's breathing zone, and a conduit that interconnects the blower unit and the delivery system for directing conditioned air from the blower unit to the delivery system. The delivery system is positioned so that it sends conditioned air around an individual's head and into the individual's personal breathing zone, thereby creating a zone of conditioned air around the individual's head.

Description

[0001] This application is a continuation of application Ser. No. 10 / 820,083, filed Apr. 6, 2004, entitled SYSTEMS FOR DELIVERING CONDITIONED AIR TO PERSONAL BREATHING ZONES, which is incorporated herein by reference, and which claims the benefit Provisional Application Ser. No. 60 / 461,306 filed on Apr. 8, 2003, and claims the benefit of Provisional Application Ser. No. 60 / 539,360 filed on Jan. 27, 2004.FIELD OF THE INVENTION [0002] This invention relates to systems for delivering conditioned air to personal breathing zones. More particularly, this invention relates to systems in the personal environment that deliver conditioned air to improve health or comfort. BACKGROUND OF THE INVENTION [0003] Asthma in the U.S. and around the world has increased at an alarming rate over the last 20 years and currently affects more than 15 million Americans. There is some speculation as to the cause of this increase, whether due to more time spent indoors in “tighter” homes with less fresh air or...

AI Technical Summary

Benefits of technology

[0010] The invention provides a system to significantly improve the air quality in a personal breathing environment. Air quality can be improved by one or more of the following: removing allergens and other harmful particles from an air stream prior to the air stream reaching the personal breathing environment; preventing allergens and other harmful particles from reaching the personal breathing environment; and conditioning the air in the personal breathing environment.

Problems solved by technology

However, individuals within the area of the unit may not experience all of the beneficial results of this particle removal because the air that is discharged from the unit is able to pick up additional harmful particles from the surrounding environment prior to reaching and being breathed in by the individuals.
