Hand dryer with sanitizing ionization assembly

摘要

A hand dryer assembly including a blower assembly for generating a moving air stream. The moving air stream passes through an air channel to an air outlet where it exits the hand dryer assembly. An ionization assembly is disposed along the air channel and emits charged ions directly into the moving air stream, sanitizing the hands of the user, the moving air steam, and the ambient air that is entrained into the moving air stream.

主权项

1. A hand dryer assembly for drying the hands of a user, said hand dryer assembly comprising:
a blower assembly for generating a moving air stream having an operational cycle with a normal airstream velocity of at least 10,000 linear feet per minute, an air channel extending from an air inlet through said blower assembly to an air outlet; an ionization assembly including a plasma power supply electrically coupled to at least two ion sources and wherein said at least two ion sources are at least partially disposed within said air channel, and wherein said ionization assembly is at least partially disposed within an outer shell and free from glass and wherein said ionization assembly is configured to avoid the production of ozone; and a motion sensor capable of detecting a user activation through the presence of the hands of the user and configured to activate said blower assembly and said ionization assembly in response to the user activation, and wherein the blower assembly and ionization assembly after removal of the user activation are configured to operate for at least a specified time interval at a reduced air stream velocity.
