Definitions

  • hair drying apparatus having means for absorbing moisture from the drying air, and having a novel arrangement whereby the moisture absorbing means is automatically re-cycled, as the apparatus is used.
  • Fig. 1 is a side elevational view, illustrating hair drying apparatus incorporating the present invention.
  • Fig. 2 is a cross-sectional detail, taken along the line 2-2 of Fig. 1, and on an enlarged scale.
  • Fig. 3 is a cross-sectional view, taken along the line 33 oi Fig. 1.
  • Fig. 4 is a cross-sectional detail taken along the line 4-4 of Fig. 2.
  • Fig. 5 is a cross-sectional detail taken along the line 5-5 of Fig. 2.
  • the present invention makes use of a blower or fan for delivering air upon the head of a subject.
  • the drying action is made more rapid by absorption of moisture from the air, thereby increasing the capacity of the drying air to absorb moisture.
  • FIG. 1 illustrates a conventional form of blower i0, connected to an air distributor II.
  • This distributor generally surrounds the head of a subject, and may be helmet shaped or otherwise designed to direct the air upon the head.
  • the air is heated by suitable means such as an electrical heating element 12, carried within the conduit 13 which connects the blower Ill with the distributor ll.
  • moisture absorbing units Ilia and 16b may be formed substantially in accordance with the disclosure of my co-pending application Serial No. 231,884, filed Sept. 27, 1938. Briefly the units consist of elongated conduits ll, alongside oi which there are suitable electrical heating elements "a and llb. Suitable heat insulating material, such as asbestos packing l9, may surround the conduits "and the heating elements Na and llb, and
  • each conduit i1 is tilled with a porousmedium 22 capable of absorbing moisture irom the atmosphere.
  • the porous medium preferably consists of fragments of asbestos saturated with calcium chloride, and interspersed in glass wool or a like medium.
  • the distributing valve 14 may vary as to structural details, but in this instance it consists of a body 24 having a cylindrical bore 26.
  • the body 24 is attached directly to one side of the blower l0, so that the intake of the blower is directly I connected with the cylindrical bore 26.
  • the valve body is also formed to provide the passages 21a and 21b, which connect with the upper ends of the conduits l1, and with the two vents or ports 28.
  • Segment 32 is provided with a recess 24, and in the position oi. the valve member illustrated in Fig. 4, this recess is in communication with duct 28, thus establishing communication betweenduct 28 and the passage 21a. Also for the positioning of the parts illustrated in Fig. 4, passage 2'") is in communication with the interior of bore 26, and thus with the intake of the blower Ill. When the'valve member ll is turned in a counterclockwise direction from the position shown in Fig. 4, to bring segment 32 into a corresponding position with respect to passage 21b, this passage is placed in communication with duct 28, while passage 21a is placed in communication with the intake of blower 10.
  • an operating handle 36 is attached to the iorward end oi shaft 28.
  • the forward end oi the valve body 24 carries an electrical switching mechanism 31.
  • This switching mechanism may vary as to details of construction, but in the instance illustrated it consists oi an' insulating disc 38, mounted upon the shaft 2!.
  • a contact blade 28 is mounted upon disc 38 and cooperates with two pairs of contacts 4
  • the a parts just described are shown enclosed within a suitable housing 44.
  • and 42 are connected in series with the heating elements its and lib, so that each set of contacts, when closed by the blade 28, supplies current to its 1 the other current supply conductor 2 is connected to one of the contacts 42, and also one 01' the contacts 4
  • Conductor 3 connects the other one of the contacts 4
  • the other one of the terminals 46 connects with a current supply conductor I.
  • the contacts H are closed and current is supplied to the heating element lfla. This serves to supply heat to the one moisture absorbing unit lta, while the other unit l6b is placed in communication with the intake of the blower l0.
  • air is drawn through the moisture absorbing unit lib and discharged as warm dry air by the blower l0.
  • the unit its is being heated, and this heat drives out moisture, which may vent in the form of vapor from the lower end of the heat absorbing unit, and also upwardly through the passage 21a, recess 34, and port 28.
  • current supply to the entire machine is interrupted.
  • the commencement of the next drying cycle the
  • .operator turns the handle 36 to its other operating position, and this serves to vent the passage Z'Ibto the atmospere through recess 34, while pasasge 21a and unit l6a are placed in communication with the intake of the blower l0. Also contacts 42 are closed to supply current to the heating element l8b. Thus during this next drying cycle air is drawn through the regenerated moisture absorbing unit 16a, while the unit lib is being heated for the purpose oi driving ofi moisture.
  • each unit comprising a conduit for passage of air and moisture-absorbing materials within the conduit adapted to be dried by application of heat, electrical heating means associated with both said units, and serving to heat said units when energized, an air blower, valve means for controlling communication between said units and said blower, said valve means having at least two openings therein for establishing communication between said blower and said units respectively, said valve being regenerated for the next means also having passage means formed therein for establishing communication from either of said units to the atmosphere, said valve means having one position in which one oi.” said openings establishes communication between said blower and one of said units and said passage means vents the other of said units to atmosphere, and said valve means having a second position in which the other of said openings establishes communication between said blower and said unit and said passage means vents said one unit to the atmosphere, electrical switching means for controlling flow of current through said electrical heating elements, whereby either one of said elements can be electrically heated, and a common operating
