Hands free blow dryer

Abstract

A hands-free hair dryer assembly that has a concave housing assembly with an open top portion, at least one side surface, and a bottom portion having a bottom exterior surface. 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.

DETAILED DESCRIPTION OF THE INVENTION

(9) Following are more detailed descriptions of various related concepts related to, and embodiments of, methods and apparatus according to the present disclosure. It should be appreciated that various aspects of the subject matter introduced above and discussed in greater detail below may be implemented in any of numerous ways, as the subject matter is not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

(10) Referring to the Figures, FIG. 1 illustrates a hands-free hair dryer assembly 10 for a user which includes a concave housing assembly 100 having an open top portion 110 and at least one sidewall surface 150. At least one air inlet 130 is disposed through the at least one sidewall surface 150, which channels air through to the open top portion 110 that is treated (heated or warmed) before flowing through the top portion 110, the top portion 110 having a plurality of hole members 125 disposed through a bottom exterior surface 120. A plurality of removable, protruding duct or channel members 160 disposed within the concave housing assembly 100 are designed for broadening the airflow distribution and changing the speed of the airflow through the concave housing assembly 100. The concave housing assembly 100 is divided into a first housing portion 101 that is wider than a second housing portion 102, the second housing portion 102 is designed to nest at least partly inside the first housing portion 101 to change the dimensions of the open top portion 110 as the second housing portion 102 is extended from or retracted into the first housing portion 101.

(11) In this example embodiment, a tilt control button 140 is disposed on the at least one sidewall surface 150. An open polymer rim member 170 circumscribes an upper rim portion of the concave housing assembly 111 designed to further channel airflow emanating up from the protruding duct members 160 and open top portion 110. At least one removable additional row of protruding duct members 163 can be disposed within the concave housing assembly 100 when the concave housing assembly 100 is at least partly extended.

(12) FIGS. 1 and 2 illustrate a control panel assembly 200 designed to allow the user to control the heat level via a heat switch 210 and the airflow speed via an air flow speed switch 220. A power switch 230 is on the control panel 200 along with a size control switch 240 to extend or contract the second housing portion 102 from the first housing portion 101 thereby making adjustments to accommodate different hair lengths of the user.

(13) FIG. 3 illustrates an electrical fan assembly 300 designed to heat and blow air drawn through the at least one air inlet 130. An airflow distribution plenum 350 is disposed within the concave housing assembly 100 and is designed to direct heated or non-heated air out the open top portion 110. The control assembly 200 is electrically coupled to a power supply from a power supply input 307 designed 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. A rechargeable battery member 308 may be disposed within the concave housing assembly 100, the rechargeable battery member 308 designed to store and provide power.

(14) FIG. 4 illustrates a right side view of the concave housing assembly 100.

(15) FIG. 5 illustrates a left side view of the concave housing assembly 100.

(16) FIG. 6 illustrates a top view of the concave housing assembly 100.

(17) FIG. 7 illustrates a bottom view of the concave housing assembly 730 having a bottom exterior surface 735. A support structure 750 is designed to at least partly separate the bottom exterior surface 735 from a support surface on which the hands-free hair dryer assembly 100 is located.

(18) FIGS. 8A through 8C illustrate 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 800. Setting controls electrically coupled to a power supply designed to control at least one or more of power, heat level, airflow speed, height, and tilt 810. 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 designed to nest at least partly inside the first housing portion 820. Blowing via at least one electrical fan assembly designed 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 830. Directing the air drawn through the at least one air inlet into an airflow distribution plenum disposed within the concave housing assembly and designed to direct heated air out the open top portion 840. Channeling the air upward and outward through a plurality of protruding duct members disposed within the concave housing assembly designed to broaden the airflow distribution and change the speed of the airflow 850. The method may further involve 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 860. The method may further involve 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 870. The method may further involve 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 880. The method may further involve drawing from and charging a rechargeable battery member disposed within the concave housing assembly, the rechargeable battery member designed to store and provide power 890.
