As is best shown in FIGS. 1 and 4, the hair dryer with mist feature 10 of the present invention is characterized by two releasably interconnected portions including a main housing 12 and a second housing or pump-reservoir body portion 14.
The housing 12 is formed of a pair of front and'rear side shells l6 and'l8 which aresecured together along a longitudinal vertical plane. as best illustrated in FIG. 5, by a series of screw fasteners 20 in a manner well known in the art. The housing 12 as viewed in side elevation and as shown in FIG. 1 is generally rectangular with a top wall 22, front and rear side walls 24 and 25,
and front and rear end walls 26 and 27. The bottom is left open to define a heated air outlet 28. A separate grill member 30 is suitably mounted in the open bottom of the housing 1 2 to prevent a persons fingers from coming into contact with a heater assembly 32 which is mounted within the housing 12 adjacent the air outlet 28. As viewed in end elevation, as shown in FIG. 5, the upper portion of the housing 12 is rounded with the lower portion of the front and rear side walls 24 and 25 converging slightly in a downward direction.
The top wall 22 and the upper curved or rounded portions of the front and rear side walls.24 and 25 are extended rearwardly of the rear end wall 27 whereby the hair dryer with mist feature shown in FIGS. 1 and,
to define a handle or handgrip portion '34 which may be described as projecting rearwardly in a longitudinal direction from the rear end wall 27. The portions of the front and rear side shells l6 and 18 defining the handle 34 are characterized by bottom walls which provide a bottom wall or underside 36 of the handle 34, which bottom wall 36 generally meets the rear end wall 27 at a right angle, as shown at 37 in FIGS. 1, 2 and 4. As will be described ingreatcr detail hereinafter, the second housing or pump-reservoir body portion 14 providing the mist feature of the hair dryer is removably at tachable to the housing 12in the right angle corner 37v defined by the rear end wall 27 and the adjacent portion of the underside 36 of the handle 34-. The external is evident in FIG. 1.
The grill member is provided with a pair of spring clips 38 which permit a variety of comb and brush attachments, such as the comb 39 shown in broken line in FIG. 5, to be attached to the hair dryer 10 in alignment with the heated air outlet 28 as may be required by different hair styling techniques.
As best illustrated in FIGS. 4 and 8, the internal components of the hair dryer 10 comprise a small 12 volt DC. motor 40 which is mounted in the handle portion 34 and a cross-flow tangential fan 42 of a well known type which is disposed in the upper portion of the housing 12 above the heated air outlet 28. One end of the fan 42 is drivingly supported by a drive shaft 43 of the motor40 with the other end of the fan 42 being supported on a stub shaft 44 which is mounted in a suitable bearing 46. The upper portion of the rear side wall 25 is provided with a series of vertical slots 48 (FIG. 4) which define an air inlet 49 adjacent the fan 42.
The heater assembly 32, which is mounted between the fan 42 and the air outlet 28, is characterized by a pair of cards 50 (only one of which is visible in FIG. 4) which are wound with heating elements 51a, b and c, and a thermostat 52. The heater assembly 32 is shielded and spaced from the adjacent front and rear side walls 24 and 25 of the housing 12 in a suitable m'anner.
A power cord 54 enters the housing 12 through the end of the handle 34 and is connected through a switch 56 and a rectifier 58 to the motor 40 and the heater assembly 32 by means of suitable leads or wires. As shown in the circuit diagram of FIG. 8, the thermostat 52 is connected to one side of the power supply with the switch 56 being connected to the otherside. The switch 56 is a three-position switch having Off," Low Heat and High Heat" positions. As is evident from the circuit diagram of HO. 8, the motor 40 in this embodiment operates at the same speed in either the Low Heat" or High Heat" positions of the switch 56. The switch56 has a thumb-engageable button 57 which protrudes upwardly through a suitable slot 60 formed in the top wall 22 of the handle 34 for convenient slidable actuation by a person holding the hair dryer 10.
The second housing or pump-resevoir body portion 14 is characterized by front and rear side walls 62 and 63, a front end wall 64 having a forwardly raised'surjface 66, a top wall '68, a rear end wall which is curved and inclined inva downward direction toward the front end wall 64, and a bottom wall 72 which is provided with a recess 74 adapted to receive a spray nozzle76. The interior of the body portion 14 comprises a fluid reservoir 78 which may be filled through a filler port 80 formed in the top wall 68. The port 80 is normally closed by a cap 82 which has an arm portion 83 secured to the top wall 68 so that the cap 82 will not be accidentally misplaced.
As will be evident hereinafter, the'filler cap 82 may be removed for refilling the reservoir 78 only when the pump-reservoir body portion 14 is disassembled from the housing 12, as a safety feature. As this hairdryer 10 is an electrical device which is plugged into the home power supply while in use, it is of great importance that a person using the hair dryer for drying and styling his or her hair not be able to refill the reservoir by holding the whole unit under a household water tap while same is plugged in.
A tubular gland 84 formed in the top wall 68 of the body portion 14 projects both inwardly and outwardly of the top wall 68. An end wall 86 of the spray nozzle recess 74 provided with a tubular boss 88 which extends into the reservoir 78 with the bore 89 thereof being axially aligned with the tubular gland 84. A stem portion 90 of the spray nozzle 76 is press-fitted in one end of the bore 89. A generally cylindrical pump housing 92 has an open end telescopically secured on the inwardly projecting portion of the tubular gland 84 whereby to define a pump chamber 93 and a tubular stem end 94 press-fitted in the other end of the bore 89 whereby to define an outlet from the pump chamber 93 to the spray nozzle 76.
a piston 96 in the pump chamber 93 is mounted on the end of a piston rod 98 which extends outwardly of the body portion 14 through the tubular gland 84 formed in the top wall 68 thereof. A sealing member 100 is provided between the piston rod 98 and the tubular gland 84 and a return spring 102 seated between a pair of spring retainers 103 and 104 serves to bias the piston rod 98 toward its outermost position.
The pump housing 92 is provided with an inlet port 106 having an inlet tube 108 connected thereto with a check valve 110 and a screen 112 being provided at the other end of the inlet tube 108 to filter fluid drawn into the pump chamber 93 from the reservoir 78. A pressure relief check valve 114 is also provided in the top wall 68 of the body portion 14.
Projecting upwardly from the periphery of the top wall 68 of the body portion 14 and spaced slightly inwardly of the side and rear outer surfaces thereof is an upstanding peripheral flange formation 116.
The front and rear side portions of the flange formation 116 are provided with aligned notches 118 and 119 for a purpose to be described hereinafter.
The rear end wall 27 of the housing 12 is provided with a shallow recess 120 which is adapted to receive the forwardly raised front surface portion 66 of the pump-reservoir body portion 14 and the portion of the underside 36 of the handle 34 adjacent the rear end wall 27 is provided with a shallow recess 122 which is adapted to receive the upstanding flange formation 1 16 disposed at the upper end of the pump-reservoir body portion 14. Thus, when the pump-reservoir body portion 14 is positioned in the right angle 37 defined by the rear end wall 27 and the underside 36 of the handle 34, the front and rear side walls 62 and 63 and the curved rear wall 70 of the body portion 14 blend evenly into the adjacent surfaces of the housing 12 to provide a hair' dryerhavinga very pleasing appearanceqas evidenced by FIG. 1. Latch means to be further described hereinafter are provided for releasably retaining the pump-reservoir body portion or second housing 14' in operable position against the rear end wall'27 of the housing 12 and against the underside 36 of the handle 34.
It is noted that when the pump-reservoir body portion 14 is attached to the housing 12, the filler po'rt cap 82 is not exposed and may not be opened to refill the reservoir, 78. In addition, an integral-transverse depending rib 124 is provided in .the shallow recess 122, which rib 124 is seated against the filler port cap 82, as is best illustrated in FIG. 2, whereby to prevent accidental loosening of same and the possible leakage of fluid from the reservoir 78 into the electrical circuitry of the hair dryer 10. The notches 118 and 119 in the upstanding flange formation 116 accomodate the rib 124 and also aid in positioning the pump-reservoir body portion 14 relative to the housing 12.
As is best illustrated in FIG. 2, an opening 126 is pro.- vided in the shallow recess 122 to accomodate the pistonrod 98 wherebysame is permitted to project generally upwardly into the interior of the handle 34. A bellcrank type lever 128 is pivotally mounted in an opening 130 provided in the underside 36 of thehandle 34 on a suitably supported pivot pin 132. The lever 128 is characterized by a finger-engageable portion 134 whichprotrudes from the underside 36 of the handle 34 for convenient actuation by one holding the hair dryerwhile drying and styling his or her hair. The lever 128 is further characterized by an actuating portion 136 which is disposed within the handle 34 and which is provided with an enlarged end portion 137 which is engageable with theend of the piston rod 98. Thus, when the finger-engageable' portion 134 of the lever 128 is actuated, the piston 96 is forced inwardly of the pump chamber 93 by engagement of the actuating portion 136 of the lever 128 with the end of the piston rod 98 whereby a spray of mist is discharged from the spray nozzle 76 As illustrated in FIGS. 1 and 4, the
housing 12 is characterized by a hook-and-notch arrangement wherein a vertically disposed recessed and undercut notch 138 is formed in the front surface 66 of the pump-reservoir body portion 14 in a manner such that a downwardly extending latch member 140 is provided at the upper end of the notch 138. An upwardly directed hook member 142 engageable with the latch member 140 as illustrated in FIG. 2) is formed on a latching bar 144 which is disposed in the housing 12 for vertical sliding movement adjacent the inner surface of the rear end wall 27. Suitable guide structure is provided in the housing 12 for guiding the vertical sliding movement of the latching bar 144.
As best illustrated in FIGS. 5 and 7, the latching bar 144 is characterized by a generally rectangular body portion 146 which is disposed generally parallel to the rear end wall 27 with the integral hook member 142 projecting rcarwardly from the lower edge thereof and through a vertically extending slot 148 formed in the rear end wall 27 for latching engagement with the latch member 140 provided on the pump-reservoir body portion 14. To facilitate actuation of the latching bar 144, an integral knurled fingerengageablc button 150 projects from an upper portion of the latching bar 144 through a vertical slot 152 formed in the rear sidewall 25 of the housing 12. The button 150 maybe conveniently actuated by anyone using the hair dryer 10 to assemble or disassemble the pump-reservoirbody portion 14 to or from the housing 12. To bias the latching bar 144 upwardly whereby to resiliently retain the hook member 142 in latching engagement with the latch member 140, a spring-engageable abutment 154 is integrally formed on the latching bar 144 and the free end of a leaf spring 156, whose opposite end is sedurely anchoredin the housing 12, as shown at 158 in FIG. 7, is
end wall 27 after'which the button 150 is released' whereupon the latching bar 144 is urged upwardly by the spring 156 with the hook member 142 moving upwardly 'into latching engagement with the latch'member 140' on the body portion or second housing 14. To detach the pump-reservoir body portion 14 from the housing 12, the button 150 is moved downwardly to disengage the hook member 142 from the latch member 140 and the body portion 14 if removed.
To use the hair dryer 10 for wet styling, the pumpreservoir body portion 14 is first detached from the housing 12 and the reservoir 78 is filled after which the body portion l4 is latched to the housing 12 in the manner described herein. The power cord 54 is then plugged into an electrical outlet and the hair dryer 10 is gripped by the handle 34. Theswitch button ,57 may be moved by the thumb into one of the two heat" positions and when a spray mist is desired the lever portion l34.is merely squeezed by the finger. It is evident that with this personal care appliance, wet styling may be accomplished without the necessity of putting down the styl er, turning on a faucet, and applying water directly tothe hair.
While there has been shown and described a single embodiment of the present invention, it will be apparent to those skilled in the art that various changes and modifications may be made withoutdeparting from the invention in its broader aspects and it is, therefore, contemplated in the appended claims to cover all such changes and modifications that fall within the true spirit and scope of the present invention.
