  • a plurality of apertures 42 are formed in the plate about the motor 17.
  • the motor When the motor is energized the incoming air will pass through the grill 40 into the chamber 37 and over the motor 17 to cool the same and through the openings 42 into the chamber 38 into the central eye portion of blower 18.
  • the blower 18 will exhaust the air within chamber 38 through the tangential exhaust 19' through and over the heater 19 into the hose storage compartment or passageway 21 and through the hose 23 into the cap 24 assuming that the hose 23 has been withdrawn and connected to the cap as indicated in FIG. 1.
  • the collapsible cap 24 of course can be double layered to provide an inflatable air distributing manifold for drying hair when the cap is positioned on the users head.
  • the heater 19 is a sub-assembly which is well known in the art. It comprises a surrounding metallic shield 19" which has a pair of heater wound insulating cards 19" mounted therein.
  • the heater 19 is mounted on the plate 20 by means such as a rivet 43 passing through tabs formed on the shield 19" and the plate 20.
  • Heater 19 is preferably positioned on the left hand side of the plate 20 when viewing FIG. 4 so that it is directly aligned with air exhausted by the fan 18.
  • the motor 17, the blower 18, and the heater 19 are preassembled with the plate 20.
  • plate 20 is positioned in the scroll wall 29 of shell 13 by locating the tabs 31 in the notches 32. Thereafter plate 24 ⁇ can be fastened in position by means such as screws 35, and then shell 12 is superposed on shell 13 and connected to shell 13 by means such as screws 33.
  • the passageway 21 besides comprising a hose storage compartment also operates as an exhaust passageway or air outlet for the hair dryer.
  • the inner end of hose 23 is provided with a fitting or collar 44.
  • the fitting 44 and therefore the inner end of hose 23 is retained captive in the passageway 21 but can move therein in opposite directions throughout the length thereof.
  • the passageway 21 is provided with a stop element 45 adjacent to the heater 19 so as to limit inward movement of the fitting 44.
  • the passageway 21 is provided with an integral annular ring or flange 46 to limit outward movement of the fitting 44.
  • the hose 23 is assembled with the hair dryer by positioning it in the passageway 21 prior to closure of the two shells 12 and 13 on each other.
  • the hose 23 was expansible to 36 inches and collapsible to about 8 inches. Therefore, the passageway 21 also had a length of about 8 inches. However, it will be appreciated that if the hose 23 is capable of being collapsed into a shorter distance then the length of the passageway 21 can be correspondingly reduced. Since the inner end of the hose is free to move for a substantial distance in opposite directions within the passageway 21, this makes it possible to reduce the actual length of hose 23 required to connect the motor-blower-heater unit to the cap 24 and still provide limited freedom of movement for the hair dryer cap user.
  • the hose 23 would have to be longer to provide the same exposed length of hose as when fitting 44 can be moved in an outward direction. Also, if fitting 44 were fixed to the outer end of passageway 21 then the length of casing 10 would have to be increased to provide the necessary hose storage space.
  • the outer end of hose 23 is also provided with an annular fitting or collar 47.
  • the collar 47 will pass through the opening 28. It will also pass through the opening 46.
  • the left hand of collar 47 is provided with a pair of diametrically positioned tabs 49.
  • the tabs 49 In order to insert the collar 47 through the opening 46 it is necessary 7 to align the tabs 49 with a pair of diametrically positioned notches 50 formed in the ring 46. After the tabs-49 are inserted past the notches 50, if the collar 47 is given a partial turn, then the tabs 49 will catch on the ring 46 to retain the hose 23 in collapsed stored position within the passageway 21.
  • the ring 46 which operates as an outer stop for the inner fitting 44 and as a releasable catch for the outer fitting 47 is spaced behind the opening 28 by a short distance so that when the hose 23 is releasably locked in stored position by having the tabs 49 catch on the ring 46 the right hand end of fitting 47 will be just flush with the end wall at the lower right hand corner of housing 10. Besides releasably locking the hose 23 in stored position in compartment 21 the fitting 47 also releasably locks the outer end of hose 23 to the hair dryer cap 24.
  • fitting 47 is provided with a pair of tabs 48 which can be snapped into an annular fitting 52 on the hair dryer cap 24 in a manner which will be obvious to those skilled in the art to removably connect the hose to the cap.
  • the fitting 47 or the fitting 52 may be constructed from flexible plastic material to facilitate this removable connection.
  • the wall 29 on the shell 13 extends across the enlargement 15 and the grill work 40 is actually formed only in that part of the peripheral portion of enlargement 15 which is in alignment with the motor-blower sub-assembly.
  • the cap and cord storage compartment 22 is defined by the wall 29 and the opposite door 27 and the walls 30 and the opposite flange portions of the shells 12 and 13 along the top of housing 10.
  • Door 27 actually comprises a hinged end panel of housing 10.
  • the opposite shells 12 and 13 are provided with integral pins 54 and the door 27 is provided with a pair of pin receiving portions 55 along the bottom thereof.
  • These integral means 54, 55 mount the door for hinged or pivoted movement about its bottom edge.
  • the upper end of door 27 has an integral depression 56 formed therein which is provided with an aperture 57 at its upper end.
  • a finger can be inserted into the depression 56 through the opening 57 to pull open on the upper edge of the door.
  • the door 27 is latched closed by a pair of tabs 53 formed on the upper edge thereof which catch in a groove 58 formed on the inside of the upper right hand corner of housing 10.
  • the door 28 may be constructed from flexible plastic material to facilitate releasable latching engagement between the tabs 53 and the notch 58.
  • the upper edge of door 27 is also provided with a notch 59.
  • the notch 59 is large enough to permit withdrawal of the cord 25 from within compartment 22 while still keeping the door closed. For example, if one wanted to dry her fingernails with the hair dryer unit it would not be necessary to withdraw the hose 23 and the cap 24 but merely the cord 25.
  • the door 27 could be kept closed after the cord 25 was withdrawn and plugged into an electrical outlet, and the hot air generated by the motor-blowerheater unit would be exhausted from the tangential exhaust 19 through the collapsed and stored hose 23 out through the fitting 47. If the fingernails were placed in front of the opening 23 the exhausted hot air would dry nail polish or the like thereon.
  • the cord 25 is shown as being permanently attached or fixed to the motor-blower-heater unit, however, it will be appreciated by those skilled in the art that the cord 25 could have a detachable connection at its inner end to the unit and the cord 25 would still be stored in the chamber 22 by coiling or bunching it up and insertin g it into the chamber 22 along with the cap 24.
  • the compartment 22 is large enough to receive the cap 24 and the cord 25 with extra room to spare.
  • a switch assembly is provided at the lower left hand corner of housing 10 for purposes of controlling the hair dryer.
  • the switch assembly comprises a switch 60 having a finger operating rotary control member 61.
  • a recessed portion 62 is provided in the lower left hand corner of the housing in alignment with the hose storage compartment 21.
  • the switch 60 is mounted radially outward of the adjacent scroll wall 29 between the wall defining recess 62 and an adjacent lug 63.
  • the rotary finger control 61 is positioned in recess 62 on a switch shaft 64 which extends through an aperture formed in the wall portion of recess 62.
  • the finger control 61 is positioned so as to be flush with the left hand end wall or panel of the hair drying casing.
  • the invention provides a low cost, lightweight, compact, and portable hair dryer in which the casing or housing for the motor-blower-heater unit is a closed carrying unit for all the necessary parts or apparatus necessary to perform a total hair drying operation.
  • the cap and cord are withdrawn from their storage compartment and the hose is withdrawn from its storage compartment.
  • the hose is connected to the hair drying cap and the hair drying cap is then positioned on the hair dryer users head.
  • the cord 25 can then be plugged into a wall socket.
