DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in which like parts are designated by
like numerals in the various views, there is shown in FIG. 1 a
perspective view of the hair dryer with mist feature, designated
generally by the reference numeral 10, which embodies our
invention. 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 16
and 18 which are secured 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 12 to prevent a
person's 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 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 16 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 in greater detail hereinafter, the second housing or
pump-reservoir body portion 14 providing the mist feature of the
hair dryer 10 is removably attachable to the housing 12 in the
right angle corner 37 defined by the rear end wall 27 and the
adjacent portion of the underside 36 of the handle 34. The external
configuration of the pump-reservoir body portion 14 is gracefully
curved whereby the outer surfaces thereof blend into the adjacent
outer surfaces of the housing 12 whereby to provide the very
pleasing appearance which is evident in FIG. 1.
The grill member 30 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 D.C. 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 motor 40 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 manner.
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 other side. The switch 56 is a
three-position switch having "Off," "Low Heat" and "High Heat"
positions. As is evident from the circuit diagram of FIG. 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
switch 56 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 surface 66, a top wall 68, a rear
end wall 70 which is curved and inclined in a 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 nozzle 76. 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 hair dryer 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 116 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 dryer having a very
pleasing appearance, as 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 port 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 provided in the
shallow recess 122 to accomodate the piston rod 98 whereby same is
permitted to project generally upwardly into the interior of the
handle 34. A bell-crank type lever 128 is pivotally mounted in an
opening 130 provided in the underside 36 of the handle 34 on a
suitably supported pivot pin 132. The lever 128 is characterized by
a finger-engageable portion 134 which protrudes from the underside
36 of the handle 34 for convenient actuation by one holding the
hair dryer 10 while 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 the end 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 spray nozzle 76 is disposed adjacent the heated air outlet
28 whereby the spray mist is provided adjacent the specific portion
of a person's hair being styled.
The latch means for releasably attaching the pump-reservoir body
portion or second housing 14 to 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 rearwardly 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
fingerengageable button 150 projects from an upper portion of the
latching bar 144 through a vertical slot 152 formed in the rear
side wall 25 of the housing 12. The button 150 may be conveniently
actuated by anyone using the hair dryer 10 to assemble or
disassemble the pump-reservoir body 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 anchored in the
housing 12, as shown at 158 in FIG. 7, is resiliently engageable
with the underside of the abutment 154.
To attach the pump-reservoir body portion 14 to the housing 12, the
button 150 is moved downwardly against the force of the spring 156
and the body portion 14 is positioned, as described herein, against
the rear 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 pump-reservoir body
portion 14 is first detached from the housing 12 and the reservoir
78 is filled after which the body portion 14 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. The switch 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 134 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 styler,
turning on a faucet, and applying water directly to the 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 without
departing 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.
