Abstract
A hand dryer comprising: a housing containing a duct defining a pathway for air through the housing from an inlet to the housing to an outlet from the housing; the duct having a longitudinal axis extending a major length of the duct; the duct in the vicinity of the inlet defining a minor length of the duct with a secondary longitudinal axis the section of the duct along the secondary longitudinal axis having a cross section transverse the secondary axis in the form of a figure having a boundary with a maximum linear dimension no more than twice a minimum linear dimension; the duct in the vicinity of the outlet defining a slot lying substantially transverse the longitudinal axis; the slot having a width at least four times greater than its height; the duct in passing from the extended volume to the slot; changing in cross section from the section to the slot to provide a relatively smooth transition in shape for the pathway from the inlet to the outlet; and following a path lying around the longitudinal axis of the section; a heater for transferring heat into air in the pathway; a fan for accelerating a flow of air along the pathway from the inlet to the outlet for egress therefrom …
