1. Apparatus adapted for intermittent operation for drying the hands of a user, having a casing, heat storage means disposed within said casing comprising a body of material having a substantial heat storage capacity, air inlet being provided through said casing and forming an air inlet from the atmosphere, said air passages being in close proximity to said body of material and in good heat transferring relation therewith to a downwardly directed outlet through which air will flow toward a drying area where the hands of the user may be located to be dried, an air blower located in said air passage, an electric motor for driving said blower, an electric heating element in good heat transferring relation to said body of material for heating air to a drying temperature as air is moved by said blower, an electric circuit adapted for substantially continuously supplying energy to said heating element thereby supplying heat to said heat storage means at a relatively slow rate, a thermostatic switch connected to said heating element for turning the same '"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' and '"'"''"'"''"'"''"'"'off'"'"''"'"''"'"''"'"' maintaining a predetermined temperature of said heat storage means, and means responsive to the temperature of the heated air for controlling the speed of said blower controlling the rate of flow of heated air when the temperature of said heated air falls below a predetermined temperature resulting in a slower withdrawal of heated air from said heat storage means and permitting lowered temperature of heated air to be elevated.
