Abstract
An air blowing apparatus is disclosed having an elongate housing with an elongate scroll defining an airflow passage. An elongate blower is surrounded by the scroll and adapted when energized to move air through the airflow passage. The airflow passage is partially helically-shaped to cause the moved air to be distributed into the surrounding environment in a partially helical pattern.
Claims25
