At least one air inlet is disposed through the bottom surface or the at least one side surface. At least one electrical fan assembly heats and blows air drawn through the at least one air inlet. An airflow distribution plenum directs heated air out the open top portion. A plurality of removable, protruding duct members disposed within the concave housing assembly broadens the airflow distribution and changes the speed of the airflow. The housing portions may be divided into two parts so that the hands-free hair dryer can be at least partly extended or retracted to change the dimensions of the open top portion. ## Claims ### Claim 1 A hands-free hair dryer assembly comprising: a concave housing assembly with an open top portion, at least one side surface, and a bottom portion having a bottom exterior surface, a plurality of hole members disposed through the bottom exterior surface; the concave housing assembly divided into a first housing portion and a second housing portion, the first housing portion being wider than the second housing portion, the second housing portion adapted to nest at least partly inside the first housing portion and to change the dimensions of the open top portion as the second housing portion is extended from or retracted into the first housing portion; at least one air inlet disposed through at least one or more of the bottom surface and the at least one side surface; at least one electrical fan assembly adapted to heat and blow air drawn through the at least one air inlet; an airflow distribution plenum disposed within the concave housing assembly and adapted to direct heated air out the open top portion; a plurality of protruding duct members disposed within the concave housing assembly adapted to broaden the airflow distribution and change the speed of the airflow; and a control assembly electrically coupled to a power supply adapted to allow the user to control at least one or more of power, heat level, airflow speed, height, tilt, and extension- and retraction of the second housing member disposed at least partly within the first housing member. ### Claim 2 (depends on 1) The hands-free hair dryer assembly in claim 1 wherein at least one support structure is adapted to at least partly separate the bottom surface from a support surface on which the hands-free hair dryer assembly is located. ### Claim 3 (depends on 2) The hands-free hair dryer assembly in claim 2 wherein there are at least two support structures telescopically extendable so as to change at least one or more of the height and angle of the concave housing assembly. ### Claim 4 (depends on 1) The hands-free hair dryer assembly in claim 1 wherein at least one removable additional row of protruding duct members can be disposed within the concave housing assembly when the concave housing assembly is at least partly extended. ### Claim 5 (depends on 1) The hands-free hair dryer assembly in claim 1 wherein an open polymer rim member circumscribes an upper rim portion of the concave housing assembly adapted to further channel airflow emanating up from the protruding duct members and open top portion. ### Claim 6 (depends on 1) The hands-free hair dryer assembly in claim 1 wherein a rechargeable battery member is disposed within the concave housing assembly, the rechargeable battery member adapted to store and provide power. ### Claim 7 A method of using a hands-free hair dryer assembly, the method comprising the steps of: positioning on a surface a concave housing assembly having an open top portion, at least one side surface, and a bottom portion having a bottom exterior surface, a plurality of hole members disposed through the bottom exterior surface; setting controls electrically coupled to a power supply adapted to control at least one or more of power, heat level, airflow speed, height, and tilt; using a size control to set the concave housing assembly to a desired size by changing the dimensions of the open top portion as a second housing portion is extended from or retracted into a first housing portion, the concave housing assembly divided into the first housing portion and the second housing portion, the first housing portion being wider than the second housing portion, the second housing portion adapted to nest at least partly inside the first housing portion; blowing via at least one electrical fan assembly adapted to heat and blow air drawn through at least one air inlet disposed through at least one or more of the bottom surface and the at least one side surface; directing the air drawn through the at least one air inlet into an airflow distribution plenum disposed within the concave housing assembly and adapted to direct heated air out the open top portion; and channeling the air upward and outward through a plurality of protruding duct members disposed within the concave housing assembly adapted to broaden the airflow distribution and change the speed of the airflow. ### Claim 8 (depends on 7) The method of hands-free hair dryer assembly of claim 7, the method further involving setting each of at least two support structures telescopically extendable so as to change at least one or more of the height and angle of the concave housing assembly. ### Claim 9 (depends on 7) The method of hands-free hair dryer assembly of claim 7, the method further including the step of adding at least one removable additional row of protruding duct members that can be disposed within the concave housing assembly when the concave housing assembly is at least partly extended. ### Claim 10 (depends on 7) The method of hands-free hair dryer assembly of claim 7, the method further including the step of removing at least one removable additional row of protruding duct members that can be removed from within the concave housing assembly when the concave housing assembly is at least partly retracted. ### Claim 11 (depends on 7) The method of hands-free hair dryer assembly of claim 7, the method further including the step of drawing from and charging a rechargeable battery member disposed within the concave housing assembly, the rechargeable battery member adapted to store and provide power. ### Claim 12 A hands-free hair dryer assembly comprising: a substantially cuboid concave housing assembly with an open top portion, at least one side surface, and a bottom portion having a bottom exterior surface, a plurality of hole members disposed through the bottom exterior surface; the concave housing assembly divided into a first housing portion and a second housing portion, the first housing portion being wider than the second housing portion, the second housing portion adapted to nest at least partly inside the first housing portion and to change the dimensions of the open top portion as the second housing portion is extended from or retracted into the first housing portion; at least one air inlet disposed through the right side surface and at least one air inlet disposed through the left side surface of the concave housing assembly; at least one electrical fan assembly adapted to heat and blow air drawn through the at least one air inlet; an airflow distribution plenum disposed within the concave housing assembly and adapted to direct heated air through the open top portion; a plurality of sixteen to twenty-four protruding duct members disposed within the concave housing assembly adapted to broaden the airflow distribution and change the speed of the airflow; at least two support structures telescopically extendable so as to change at least one or more of the height and angle of the concave housing assembly; and a control assembly electrically coupled to a power supply adapted to allow the user to control power, heat level, airflow speed, height, tilt, and extension-and retraction of the second housing member disposed at least partly within the first housing member. ### Claim 13 (depends on 12) The hands-free hair dryer assembly in claim 12 wherein at least one removable additional row of protruding duct members can be disposed within the concave housing assembly when the concave housing assembly is at least partly extended. ### Claim 14 (depends on 12) The hands-free hair dryer assembly in claim 12 wherein an open polymer rim member circumscribes an upper rim portion of the concave housing assembly adapted to further channel airflow emanating up from the protruding duct members and open top portion. ### Claim 15 (depends on 12) The hands-free hair dryer assembly in claim 12 wherein a rechargeable battery member is disposed within the concave housing assembly, the rechargeable battery member adapted to store and provide power.
