1. A portable hand dryer comprising:
- (a) a housing having an upper end, a lower end, a rear wall, an air inlet opening and a downwardly directed air outlet opening;
(b) an electric air blower disposed within the housing, the air blower having an air inlet side and an air discharge side; and
(c) air passageways disposed within the housing connecting the air inlet side of the air blower to the air inlet opening of the housing and connecting the air discharge side of the air blower to the air outlet opening of the housing;
wherein power for the electric air blower is provided via a male plug having at least two prongs, the male plug being attached to, and projecting outwardly from, the rear wall of the housing, the male plug being sized and dimensioned to plug into a standard household electrical power receptacle;
wherein the portable hand dryer weighs less than about 16 ounces; and
wherein the housing is adapted to be solely supported from a standard pair of vertically arranged 3-way household electrical outlets, including an upper outlet and a lower outlet, both the upper outlet and the lower outlet comprising a pair of current conducting female connectors and a single female ground connector, the housing being capable of being solely supported from the pair of 3-way outlets by (i) the frictional and mechanical forces existing between the two current conducting female connectors of the upper outlet and the male plug and (ii) the frictional forces between the female ground connector of the lower outlet and a distal prong attached to, and projecting outwardly from, the rearward wall of the housing.

Abstract
A portable hand dryer has an air blower and, optionally, an air heater. The hand dryer includes a laterally protruding male electrical plug having at least two prongs which provides electricity to the blower and which allows the hand dryer to be supported from a structure wall. In one embodiment, the male plug can be folded flush with the rear wall of the hand dryer. In another embodiment, the hand dryer also has a laterally extending distal prong which provides additional support for the hand dryer along a structure wall. In yet another embodiment, the hand dryer comprises a spacer on a rear wall of the hand dryer to separate the rear wall from the structure wall.
