Abstract: A compact hair dryer comprising a main body having a front and a rear portion. The front portion comprising a first duct surrounding a second duct, air flow passing through the second duct being heated by a heating means, air flow passing through the space between the first and second ducts being insulated from the heated air flow in the second duct. The second duct is shaped like a truncated cone of revolution, wherein a distribution means is arranged at the base of the cone to determine the amount of air flow passing through the space between the first and second ducts. A barrel extension comprising at least one peripheral tube surrounding a central tube connectable to the outlet of the hair dryer. The second duct of the hair dryer, at the air outlet of the hair dryer, arranged to be connectable to the central tube of a barrel extension.

Abstract: A silent hair dryer and a silencer for a hair dryer includes at least one casing with an inlet end and an outlet end and enclosing at least one turbine sucking in air via at least one admission orifice upstream of the turbine and expelling it downstream via at least one outlet orifice. The silent hair dryer includes at least one chamber upstream of the admission orifice and an inlet orifice for aspiration of air upstream of the chamber; the diameter of the chamber being greater than the diameter of the admission orifice and the diameter of the inlet orifice, the length and the diameter of the chamber being of such a size so as to define a volume turned as a function of the sound frequencies to be attenuated by the silencer.
