Technical Field
[0001] The present invention relates to a hair dryer and a heating member blocking electromagnetic
waves applied to the hair dryer.
Background Art
[0002] A hair dryer is a device drying wet hair on the head or the like. When power is applied
from an external source, the hair dryer draws ambient air, creates a flow of air therein,
and discharges wind therefrom. The wind discharged from the hair dryer may be cold
wind or hot wind, depending on whether or not a coil heater provided therein is operated.
[0003] The hair dryer generally includes: a housing having an air flow passage defined therein;
a blower fan creating wind in the housing by drawing ambient air and discharging the
wind from the housing; a motor unit rotating the blower fan; a heater disposed in
the air flow passage to heat the wind by transferring heat to the wind as required.
[0004] In the case of drying wet hair, the efficiency of wind with respect to drawn air
is not high, because air drawn from the outside is dispersed due to the absence of
a wind guide within the housing. Thus, although it is easy to dry an outer layer of
hair that is exposed externally, the hair dryer must be used for an extended period
of time to dry an inner portion of the hair adjacent to the human body, e.g. the scalp,
which is problematic. In addition, due to the use of the hair dryer for an extended
period of time, a portion of hair may be excessively dried, leading to hair damage
in which dried hair is cracked.
[0005] In addition, in the hair dryer, a heater generates heat using electric resistance
of a Nichrome wire containing nickel (Ni), which is exposed without a cover, by applying
electric current to the Nichrome wire. The heat, generated by the heater is transferred
to the wind, thereby producing hot wind. However, such a heat-generating method emits
electromagnetic waves and fine dust. When such electromagnetic waves or fine dust
arrive at a portion of the human body, as well as hair on the body portion, a harmful
effect to the human body may be caused. This issue has been widely discussed.
[0006] In order to overcome the above-described problems, development for improving the
performance of hair dryers to realize high efficiency and block electromagnetic waves
has been continuously performed. For example, patent documents, such as Korean Patent
No.
10-1155135 (dated June 4, 2012; titled "
LED ATTACHABLE/
DETACHABLE HAIR DRYER"), Korean Patent No.
10-0998333 (dated November 29, 2010; titled "
HAIR DRYER"), and Korean Registered Utility Model No.
20-0224653 (dated March 9, 2001; "
HAIR DRYER BLOCKING ELECTROMAGNETIC WAVES"), may be suggested.
[0007] However, according to performance-improved hair dryers disclosed in the related art,
such as the above-presented patent documents, near infrared (IR) radiation cannot
reach a portion of hair adjacent to the scalp when thick and wet hair is tangled.
In particular, when a female user having relatively long hair is drying the hair,
the time taken for drying the hair is not substantially reduced, which is problematic.
[0008] In addition, a shield sheet is attached to an inner portion of a hair dryer in order
to block harmful electromagnetic waves radiated from the inside of the hair dryer.
However, when the hair dryer has been used for a long period of time, the electromagnetic
interference (EMI) shielding performance of the hair dryer is deteriorated, which
is problematic.
Disclosure
Technical Problem
[0009] Accordingly, the present invention has been made keeping in mind the above problems
occurring in the prior art, and an object of the present invention is to provide a
hair dryer able to produce wind, the strength and flow rate of which are improved,
so as to dry hair in a short period of time.
[0010] Also provided is a heater used in a hair dryer to block electromagnetic waves.
Technical Solution
[0011] According to an aspect of the present invention, a hair dryer may include: a housing
including an inlet provided on an open top portion thereof, such that ambient air
is drawn therethrough, an outlet through which wind created by accelerating the air
drawn through the inlet is discharged; an air blower located below the inlet to draw
the ambient air into the housing through the inlet; a wind guide allowing the air
drawn by the air blower to flow within the housing so as to accelerate the air, so
that the wind is created, and discharging the wind toward the outlet; and a rotor
unit connected to the air blower to rotate the air blower. The wind guide may include:
an intake top portion provided in a bottom surface to be more adjacent to the air
blower than remaining portions of a bottom surface of the wind guide; a discharge
bottom portion connected to the intake top portion, with a height thereof being gradually
lowered, the discharge bottom portion being gradually spaced away from the air blower;
and a curved guide shaped as a curved surface connecting circumferential portions
of the intake top portion and discharge bottom portion, so as to concentrate the wind
created from the drawn air that is accelerated while being guided from the intake
top portion to the discharge bottom portion.
[0012] According to an aspect of the present invention, provided is a heater used in a hair
dryer including: a housing including an inlet provided on an open top portion thereof,
such that ambient air is drawn therethrough, an outlet through which wind created
by accelerating the air drawn through the inlet is discharged; an air blower located
below the inlet to draw the ambient air into the housing through the inlet; a wind
guide allowing the air drawn by the air blower to flow within the housing so as to
accelerate the air, so that the wind is created, and discharging the wind toward the
outlet; and a rotor unit connected to the air blower to rotate the air blower, wherein
the wind guide includes: an intake top portion provided in a bottom surface to be
more adjacent to the air blower than remaining portions of a bottom surface of the
wind guide; a discharge bottom portion connected to the intake top portion, with a
height thereof being gradually lowered, the discharge bottom portion being gradually
spaced away from the air blower; and a curved guide shaped as a curved surface connecting
circumferential portions of the intake top portion and discharge bottom portion, so
as to concentrate the wind created from the drawn air that is accelerated while being
guided from the intake top portion to the discharge bottom portion. The heater may
be able to increase a temperature of the wind as required. The heater may include:
an electric heat generator generating heat in response to electric energy applied
from an external source; an upper heat dissipating member mounted on a top portion
of the electric heat generator to dissipate heat generated by the heat generator to
an upper space; a lower heat dissipating member mounted on a bottom of the electric
heat generator to dissipate heat generated by the heat generator to a lower space;
and heater connectors located on both sides of the electric heat generator to connect
the electric heat generator, the upper heat dissipating member, and the lower heat
dissipating member to the housing. The electric heat generator may be located in an
inner space surrounded by the upper heat dissipating member, the lower heat dissipating
member, and the heater connectors, such that electromagnetic waves of the electric
heat generator are blocked.
Advantageous Effects
[0013] According to the hair dryer according to an aspect of the present invention, since
the hair dryer includes the housing, the air blower, the wind guide, and the rotor
unit, air drawn from the outside is guided in a predetermined direction while maintaining
a concentrated state instead of being dispersed. In this manner, the drawn air is
converted into accelerated wind, which is then discharged. The wind strength and flow
rate performance of the hair dryer are improved, so that hair can be dried in a short
period of time.
[0014] According to the heater of the hair drier according to an aspect of the present invention,
the heater includes the electric heat generator, the upper heat dissipating member,
the lower heat dissipating member, and the heater connectors. The electric heat generator
is located in an inner space defined by the upper heat dissipating member, the lower
heat dissipating member, and the heater connectors, so that fine dust and electromagnetic
waves generated by the electric heat generator can be prevented from exiting outwards.

[0018] Referring to FIGS. 1 to 11, the hair dryer 100 is configured to dry hair, and includes
a housing 111 and 115, an air blower 120, a wind guide 160, and a rotor unit 140.
[0019] The term "hair" used herein means hair protruding from the skin of the human body.
Although term "hair" in the hair dryer 100 according to the present embodiment refers
to the hair of the head of the human from among various types of hair, this is merely
illustrative, and the term is not limited to the hair of the human.
[0020] According to the present embodiment, the hair dryer 100 further includes a heater
150, a temperature sensor 105, a function selector 173, and a controller 176.
[0021] The housing 111 and 115 include an inlet 114 and 117 provided on an open top portion
thereof, such that ambient air is drawn therethrough, an outlet 182 and 184 through
which wind, created by accelerating the air drawn through the inlet 114 and 117, is
discharged.
[0022] According to the present embodiment, the housing 111 and 115 further includes backflow
prevention protrusions 181 and 183.
[0023] More specifically, the housing 111 and 115 is made of a synthetic resin, such as
plastic, and is comprised of a first housing section 111 and a second housing section
115 provided separately. When the first housing section 111 and the second housing
section 115 are connected to each other or fitted to each other, a hollow inner space
is defined, such that components can be accommodated in the inner space.
[0024] The first housing section 111 includes: a first handle portion 112 extending a predetermined
length, allowing a user to hold the handle portion 112 by a hand to adjust the position
and direction thereof; a first body 113 having a wind flow passage defined therein;
a first inlet-forming hole 114 provided as an open area in a portion of one end portion
of the first body 113; and a first outlet-forming hole 182 provided as an open area
in a portion of the other end portion of the first body 113.
[0025] The second housing section 115 includes: a second handle portion 116 extending a
predetermined length, allowing a user to hold the handle portion 116 by a hand to
adjust the position and direction thereof; a second body 118 having a wind flow passage
defined therein; a second inlet-forming hole 117 provided as an open area in a portion
of one end portion of the first body 113; and a second outlet-forming hole 184 provided
as an open area in a portion of the other end portion of the first body 113.
[0026] When the first housing section 111 and the second housing section 115 are fitted
to each other, an open portion of the first inlet-forming hole 114 and an open portion
of the second inlet-forming hole 117 are connected to each other in a corresponding
manner, thereby forming a circular open area serving as an entrance. The open area
provided as above forms the inlet 114 and 117.
[0027] In addition, when the first housing section 111 and the second housing section 115
are fitted to each other, an open portion of the first outlet-forming hole 182 and
an open portion of the second outlet-forming hole 184 are connected to each other
in a corresponding manner, thereby forming a circular open area serving as an exit.
The open area provided as above forms the outlet 182 and 184.
[0028] According to the present embodiment, the inlet 114 and 117 and the outlet 182 and
184 are located to be perpendicular to each other. Then, the air drawn while flowing
downwards in the vertical direction forms rotating wind within the housing 111 and
115. Since the wind created in this manner additionally has rotating force due to
the rotation, the rotating wind may be stronger than wind discharged after having
been drawn in a horizontal direction, created by a typical hair dryer.
[0029] In addition, the inlet 114 and 117 is provided a hollow circular portion, with the
inner surface of the inlet 114 and 117 having a shape conforming to that of the circumferential
portion of the wind guide 160. Accordingly, this configuration can prevent wind created
by the wind guide 160 from leaking through a space between the inlet 114 and 117 and
the wind guide 160.
[0030] In addition, the inlet 114 and 117 has a greater size than the other components of
the housing 111 and 115, such that a greater amount of air can be drawn. The first
handle 112 and the second handle portion 116, provided below the inlet 114 and 117,
have a smaller size than the inlet 114 and 117, but are extended in length, such that
the user can easily hold the handle by a hand.
[0031] Reference numeral 10 indicates a power cable connected to an external power source
to supply electricity to the hair dryer 100. Reference numeral 102 is an impurity
filter provided in the form of a net to filter impurities so that, when air is drawn
into the hair dryer 100, impurities do not enter along with the air.
[0032] In addition, reference numeral 101 is a hood connected to the end portion of the
outlet 182 and 184 of the housing 111 and 115 to concentrate wind and form a passage
of the wind, so that the wind can be concentrated in a specific position while being
discharged through the outlet 182 and 184.
[0033] According to the present embodiment, the first handle portion 112 and the first body
113, as well as the second handle portion 116 and the second body 118, are provided
as integral portions. Alternatively, these components may be provided as foldable
components that can be folded while being separated as two portions in order to minimize
a storage space thereof.
[0034] The backflow prevention protrusions 181 and 183 protrude a predetermined length within
the housing 111 and 115 to allow the wind, created by the wind guide 160, to flow
in the direction of the outlet 182 and 184, but prevent the wind from flowing backwards
or entering in the direction of the wind guide 160 from the outlet 182 and 184.
[0035] Specifically, the backflow prevention protrusions 181 and 183 include a first backflow
prevention protrusion 181 and a second backflow prevention protrusion 183. The first
backflow prevention protrusion 181 is located on a portion of the first body 113 to
be more adjacent to the air blower 120, and protrudes from the top surface of the
first body 113 in a vertical direction, extending to a height spaced apart from the
bottom surface of the first housing section 111 by a predetermined distance. The second
backflow prevention protrusion 183 is located on a portion of the second body 118
to be more adjacent to the air blower 120, and protrudes from the top surface of the
second body 118 in a vertical direction, extending to a height spaced apart from the
bottom surface of the second housing section 115 by a predetermined distance.
[0036] When the wind, created by the acceleration of the air during passing by the wind
guide 160, has passed from the wind guide 160, the wind is dispersed within the first
body 113 and the second body 118. The dispersed wind may collide with the inner wall
of the first body 113 and the second body 118. Then, the wind may re-enter the wind
guide 160 while flowing backwards.
[0037] The first backflow prevention protrusion 181 and the second backflow prevention protrusion
183 provide walls within the first housing section 111 and the second housing section
115, so as to prevent the wind from reentering the wind guide 160 while flowing backwards.
[0038] The air blower 120 is located below the inlet 114 and 117 to draw ambient air into
the housing 111 and 115 through the inlet 114 and 117.
[0039] Specifically, the air blower 120 includes a rotor body 121 rotating about the axis
of rotation and a plurality of rotor blades 122 provided on circumferential portions
of the rotor body 121, with rotor blades 122 of the plurality of rotor blades 122
being spaced apart from each other at certain distances.
[0040] The rotor body 121 is provided in the form of a hollow cylinder, and the rotor unit
140, which will be described later, is inserted into the rotor body 121. The plurality
of rotor blades 122 is provided as plates each having a predetermined area, the plates
radially extending from the circumferential portions of the rotor body 121. The rotor
body 121 and the plurality of rotor blades 122 are rotated by the rotor unit 140,
allowing ambient air to be drawn into the housing 111 and 115.
[0041] In addition, in the rotor body 121, an intake hole 123 extends through the upper
central portion, such that a portion of the air drawn into the inlet is introduced
therethrough. A discharge hole 124 is provided in the rotor body 121 to communicate
with the intake hole 123, and extends in a direction in which the outlet 182 and 184
is formed, such that a portion of the air that has passed through the intake hole
123 is discharged therethrough.
[0042] Specifically, as illustrated in FIGS. 4 and 5, the intake hole 123 extends through
the central portion of the rotor body 121 to a predetermined depth in the vertical
direction. The discharge hole 124 communicates with the intake hole 123 while being
perpendicularly bent from the intake hole 123. The discharge hole 124 extends in the
same direction in which the outlet 182 and 184 is formed.
[0043] The diameter of either the intake hole 123 or the discharge hole 124 is set to be
smaller than the size of the air blower 120, such that a vortex air flow is created
when the air portion drawn into the intake hole 123 is discharged through the discharge
hole 124. The vortex air flow pushes the wind created by the wind guide 160, which
will be described later, thereby increasing the speed of the wind. Accordingly, it
is possible to increase the efficiency of the hair dryer 100 while reducing the load
of the air blower 120.
[0044] In addition, the plurality of rotor blades 122 respectively has a recess 125 in a
portion of the outermost surface thereof. In each of the plurality of rotor blades
122, the recess 125 is depressed with respect to the other portions of the outermost
surface in order to increase the flow rate of the wind pushed by the plurality of
rotor blades 122.
[0045] Specifically, unlike rotor blades of a typical turbine, the plurality of rotor blades
122 has increased strength due to the recess 125 formed in substantially the central
portion of the outermost portion of each rotor blade 122. Due to this configuration,
the plurality of rotor blades 122 can firmly support itself while pushing the wind,
and vibration and noise produced during the rotation of the plurality of rotor blades
122 can be reduced.
[0046] The wind guide 160 includes an intake higher-surface portion 162, a discharge bottom
portion 163, and a curved guide 161. The intake higher-surface portion 162 is a portion
of the bottom surface of the wind guide 160, which is more adjacent to the air blower
120 than the remaining portions of the bottom surface. The discharge bottom portion
163 is connected to the intake higher-surface portion 162, with the height thereof
being gradually lowered, and is gradually spaced away from the air blower 120. The
curved guide 161 has the shape of a curved surface connecting the circumferential
portions of the intake higher-surface portion 162 and discharge bottom portion 163,
so as to concentrate the wind created from the drawn air that is accelerated while
being guided from the intake higher-surface portion 162 to the discharge bottom portion
163.
[0047] As illustrated in FIG. 7, the width between the intake higher-surface portion 162
and the discharge bottom portion 163 is set to be narrower than the diameter of the
wind guide 160, corresponding to the maximum-width thereof, such that the wind is
not dispersed before being discharged from the wind guide 160 after having been created.
[0048] In addition, with respect to the direction illustrated in FIG. 7, the intake higher-surface
portion 162 is located to the left, and the discharge bottom portion 163 is located
to the right. The height of the discharge bottom portion 163 is gradually lowered
with respect to the height of the intake higher-surface portion 162. Accordingly,
the inner surface (of the wind guide 160) is inclined like an inclined surface of
a screw.
[0049] Due to the above-described configuration, a space between the air blower 120 and
the discharge bottom portion 163 gradually increases in a space defined between the
air blower 120 and the intake higher-surface portion 162, in the direction from the
intake higher-surface portion 162 to the discharge bottom portion 163. In this space,
the wind created by the rotation and the acceleration gradually accumulates, such
that the amount of the wind gradually increases, in the direction from the intake
higher-surface portion 162 to the discharge bottom portion 163. Finally, the wind
having a maximized amount is discharged through the discharge bottom portion 163,
so that the flow rate of the hair dryer 100 is increased.
[0050] The curved guide 161 is a sidewall having a predetermined height, extending along
the curved surfaces of the intake higher-surface portion 162 and the discharge bottom
portion 163, so as to prevent the rotating wind from being dispersed. Thus, the overall
shape of the wind guide 160 is similar to that of a bowl.
[0051] Reference numeral 164 is a circular wind guide through-hole extending through the
central portion of the curved guide 161, such that the rotor unit 140 is inserted
into the wind guide through-hole 164 to be connected to the air blower 120.
[0052] Reference numeral 165 is a wind guide holder to which the rotor unit 140 is connected.
The wind guide holder 165 fixes the rotor unit 140, the wind guide 160, and the housing
111 and 115 connected to each other.
[0053] Reference numeral 166 is a wall provided on a bottom portion of the intake higher-surface
portion 162 in order to prevent a portion of the concentrated and accumulated wind
from moving backwards to the intake higher-surface portion 162 due to the vortex flow
when the wind is discharged from the discharge bottom portion 163.
[0054] In addition, according to the present embodiment, the wind guide 160 further includes
a boundary portion 167 by which the curved guide 161 is connected to the inner surface
extending from the intake higher-surface portion 162 to the discharge bottom portion
163.
[0055] The intake higher-surface portion 162 and the discharge bottom portion 163 are provided
as a connected curved surface surrounding the wind guide through-hole 164, with the
width gradually decreasing in the direction from the intake higher-surface portion
162 to the discharge bottom portion 163.
[0056] The curved guide 161 is shaped as a curved surface surrounding the intake higher-surface
portion 162 and the discharge bottom portion 163, with the wind guide through-hole
164 being located in the central portion. The curved surface of the curved guide 161
gradually widens as extending from a portion connected to the intake higher-surface
portion 162 to a portion connected to the discharge bottom portion 163.
[0057] Thus, the boundary portion 167 is shaped as a circular portion extending around the
center of the wind guide through-hole 164. The boundary portion 167 gradually approaches
the wind guide through-hole 164 in the direction from the intake higher-surface portion
162 to the discharge bottom portion 163. One end portion of the boundary portion 167
is in the same direction as the discharging direction of the discharge bottom portion
163.
[0058] Due to the above-described configuration, in a portion adjacent to the intake higher-surface
portion 162, the area between the boundary portion 167 and the intake higher-surface
portion 162 is formed relatively wide, such that a large amount of air can be drawn
therethrough. In the discharge bottom portion 163, the space between the boundary
portion and the discharge bottom portion 162 is formed relatively narrow, such that
the movement of the air can be accelerated, so that the speed of the wind can be further
relatively increased when the wind is created.
[0059] In addition, since both the discharge direction of the discharge bottom portion 163
and the direction of the end portion of the boundary portion 167 are the same as the
direction of the outlet 182 and 184, the boundary portion 167 can guide the wind so
that the accelerated wind can smoothly move toward the outlet 182 and 184.
[0060] In addition, the accelerated wind is created in the space between the wind guide
160 and the air blower 120, since the wind guide 160 is located below the air blower
120. According to this configuration, it is possible to increase the flow rate of
the wind while reducing the wind-creating space, compared to a related-art hair dryer
in which the wind is created in a side space of a blower fan.
[0061] Although the present embodiment has been described that the air blower 120 and the
wind guide 160 are applied to the hair dryer 100, this is merely illustrative, and
the air blower 120 and the wind guide 160 may be used in an air purifier, a humidifier,
a ventilator, etc.
[0062] The rotor unit 140 is a structure connected to the air blower 120 to rotate the air
blower 120. The rotor unit 140 includes a rotor 141 rotating the air blower 120 and
a rotor housing 143 accommodating and protecting the rotor 141.
[0063] According to the present embodiment, the rotor unit 140 further includes a rotor
noise reducing member 142 disposed between the rotor housing 143 and the rotor 141.
[0064] The rotor housing 143 is made of a Permalloy to prevent electromagnetic waves generated
by the rotor 141 from exiting.
[0065] Here, the Permalloy is an alloy of nickel (Ni) and iron (Fe), having a significantly
high level of permeability. The high level of permeability may increase absorption
loss, thereby providing a shield to block electromagnetic waves.
[0066] The rotor 141 is directly connected to the air blower 120 to rotate the air blower
120, and may be implemented as an electric motor.
[0067] The rotor noise reducing member 142 is made of a metal, such as aluminum (Al) or
stainless steel, and is in the shape of a plate having a predetermined area to surround
the rotor 141 in the circumferential direction. The rotor noise reducing member 142
may block noise produced during rotation of the rotor 141, so that the noise does
not spread outwards.
[0068] The heater 150 is disposed on a path along which the wind blows, and is able to increase
the temperature of the wind as required. The wind is heated by the heater 150, thereby
generating hot wind.
[0069] Specifically, the heater 150 includes an electric heat generator 151 generating heat
in response to electric energy applied from an external source, an upper heat dissipating
member 145 mounted on the top portion of the electric heat generator 151 to dissipate
heat generated by the heat generator 151 to an upper space, a lower heat dissipating
member 155 mounted on the bottom of the electric heat generator 151 to dissipate heat
generated by the heat generator 151 to a lower space, and heater connectors 152 located
on both sides of the electric heat generator 151 to connect the electric heat generator
151, the upper heat dissipating member 145, and the lower heat dissipating member
155 to the housing 111 and 115.
[0070] The electric heat generator 151 generates heat in response to electric power supplied
from an external source. The electric heat generator 151 may be implemented as an
electric heater, such as a positive temperature coefficient (PTC) heater, so as to
prevent production of fine dust in the electric heat generator 151.
[0071] Reference numeral 185 indicates power connecting lines through which electric power
is supplied from an external source.
[0072] The upper heat dissipating member 145 includes an upper heat dissipating member body
146 covering the top portion of the electric heat generator 151 and a plurality of
upper heat dissipating fins 147 extending upward from the body of the upper heat dissipating
member 145 to predetermined lengths in the vertical direction.
[0073] In addition, each of the upper heat dissipating fins 147 has an upper bent protrusion
148 provided on an outer end portion thereof. The upper bent protrusion 148 is bent
with respect to the length of the upper heat dissipating fin 147 to a predetermined
angle, and is in contact with a portion of an adjacent upper heat dissipating fin
147. Accordingly, the upper bent protrusions 148 may maintain the distances between
the adjacent upper heat dissipating fins 147 and increase the strength of the upper
heat dissipating fins 147, thereby preventing the vibration of the upper heat dissipating
fins 147.
[0074] The lower heat dissipating member 155 includes a lower heat dissipating member body
156 covering the bottom of the electric heat generator 151 and a plurality of lower
heat dissipating fins 157 extending downward from the lower heat dissipating member
body 156 to predetermined lengths in the vertical direction.
[0075] In addition, each of the lower heat dissipating fins 157 has a lower bent protrusion
158 provided on an outer end portion thereof. The lower bent protrusion 158 is bent
with respect to the length of the lower heat dissipating fin 157 to a predetermined
angle, and is in contact with a portion of an adjacent lower heat dissipating fin
157. Accordingly, the lower bent protrusions 158 may maintain the distances between
the adjacent lower heat dissipating fins 157 and increase the strength of the lower
heat dissipating fins 157, thereby preventing the vibration of the lower heat dissipating
fins 157.
[0076] The heater connectors 152 are connected to the upper heat dissipating member 145
and the lower heat dissipating member 155, on both sides of the electric heat generator
151, to cover both side surfaces of the electric heat generator 151 and connect the
electric heat generator 151, the upper heat dissipating member 145, and the lower
heat dissipating member 155 to the housing 111 and 115.
[0077] Specifically, each of the heater connectors 152 has a plurality of connecting projections
186 extending in the direction of the path of the wind to be spaced apart from each
other. The connecting projections 186 may be fitted into conforming connecting grooves
(not shown) provided in the inner surfaces of the housing 111 and 115, such that the
heater connectors 152 can be fixed to the housing 111 and 115.
[0078] In the electric heat generator 151, electromagnetic waves are relatively blocked,
compared to the case of a coil-shaped heat generator of the related art including
a Nichrome wire having high electrical resistance. In addition, since the electric
heat generator 151 is located in the inner space surrounded by the upper heat dissipating
member 145, the lower heat dissipating member 155, and the heater connectors 152,
the electromagnetic waves of the electric heat generator 151 can be double-blocked.
[0079] In addition, since the electric heat generator 151 is surrounded by the upper heat
dissipating member 145, the lower heat dissipating member 155, and the heater connectors
152, the discharge of fine dust, which would otherwise be produced from the related-art
coil-shaped heat generator including a Nichrome wire, can be double-prevented.
[0080] The temperature sensor 105 is disposed adjacent to the outlet 182 and 184 to detect
the temperature of the wind discharged through the outlet 182 and 184. According to
the present embodiment, the temperature sensor 105 may be provided in contact with
the inner surface of the housing 111 and 115 to detect the temperature of the wind
in the space that has passed through the heater 150 directly before the wind is discharged
through the outlet 182 and 184.
[0081] The function selector 173 includes a wind strength adjusting and selecting means
for selecting the adjustment of the strength of the wind discharged through the outlet
182 and 184, a temperature adjusting and selecting means for selecting the adjustment
of the temperature of the wind discharged through the outlet 182 and 184, and a time
setting and selecting means for selecting a time adjustment such that an operation
is performed for a predetermined time. The wind strength adjusting and selecting means,
the temperature adjusting and selecting means, and the time setting and selecting
means are provided with buttons 187, respectively.
[0082] When the user selects a wind strength using the wind strength adjusting and selecting
means, an instruction is transferred to the rotor unit 140 by the controller 176,
which will be described later. Then, the speed of rotation of the rotor unit 140 can
be adjusted according to the instruction, thereby adjusting the strength of the wind.
[0083] In addition, when the user selects any temperature using the temperature adjusting
and selecting means, an instruction is transferred to the heater 150 by the controller
176. Then, the amount of heat generated by the heater 150 can be adjusted, so that
the temperature of the wind discharged through the outlet 182 and 184 can be adjusted.
[0084] In addition, when the user selects any time using the temperature adjusting and selecting
means, a corresponding instruction is transferred to the controller 176. In response
to the instruction, the controller 176 can cut off the supply of power after a predetermined
time, so that the hair dryer 100 can operate for the predetermined time.
[0085] The button 187 of the function selector 173 may be, for example, a push button or
a touch button protruding from the housing 111 and 115.
[0086] In addition, the function selector 173 further includes a display 188 displaying
set values so that the user can easily check the values set using the buttons 187.
[0087] The controller 176 controls the air blower 120 and the heater 150 according to values
previously selected by the function selector 173.
[0088] Specifically, the controller 176 includes a control configuration 177 including electronic
components and a controller housing 178 having a hollow space defined therein to accommodate
and protect the control configuration 177 therein.
[0089] The controller housing 178 is made of a Permalloy, as described above, to prevent
electromagnetic waves generated by the control configuration 177 from exiting the
controller housing 178.
[0090] A housing noise reducing member 179 is further provided on the inner surface of the
controller housing 178. The housing noise reducing member 179 is made of a metal,
such as aluminum (Al) or stainless steel, and is provided as a plate having a predetermined
area to cover the inner surface of the controller housing 178. Accordingly, noise
produced by the control configuration 177 can be prevented from spreading outwards.
[0091] Although the present embodiment has been illustrated that both the rotor housing
143 and the controller housing 178 are made of a Permalloy, this is merely illustrative,
and only one of the rotor housing 143 and the controller housing 178 may be made of
a Permalloy to block electromagnetic waves.
[0092] In addition, although the present embodiment has been illustrated that the rotor
unit 140 and the controller 176 include the rotor noise reducing member 142 and the
housing noise reducing member 179, respectively, this is merely illustrative, and
only one of the rotor noise reducing member 142 and the housing noise reducing member
179 may include the noise reducing member 142 or 179 therein to prevent noise, generated
by the rotor 141 or the control configuration 177, from spreading outwards.
[0093] Hereinafter, the operation of the hair dryer 100 will be described in brief.
[0094] First, the user connects the power cable 10 of the hair dryer 100 to an external
power source, allowing electric power from the external power source to be applied
to the hair dryer 100.
[0095] Afterwards, the rotor unit 140 rotates and the air blower 120, connected to the rotating
shaft of the rotor unit 140, rotates along with the rotor unit 140, so that ambient
air is drawn into the hair dryer 100.
[0096] When the ambient air is drawn, external impurities are filtered by the impurity filter
102, so that only the air is drawn.
[0097] Afterwards, while the drawn air is being guided from the intake higher-surface portion
162 to the discharge bottom portion 163, the movement of the air is accelerated, thereby
creating wind. In the space between the air blower 120 and the intake higher-surface
portion 162, the space defined between the air blower 120 and the discharge bottom
portion 163 is gradually increased. In this space, the wind created due to the rotation
and the acceleration gradually accumulates, such that the amount of the wind gradually
increases, in the direction from the intake higher-surface portion 162 to the discharge
bottom portion 163. Finally, the wind having a maximized amount is discharged through
the discharge bottom portion 163.
[0098] Subsequently, the wind, discharged from the discharge bottom portion 163, moves to
the outlet 182 and 184 by flowing through the inside of the housing 111 and 115. Due
to the shape of the hood 101 connected to the outlet 182 and 184, the wind may be
concentrated to a specific position of the hair to dry the hair.
[0099] Here, when the user selects a high temperature using the function selector 173, the
electric heat generator 151 of the heater 150, disposed in the path along which the
wind flows, generates heat. Then, the heat is discharged through the upper heat dissipating
member 145 and the lower heat dissipating member 155 to be transferred to the wind,
so that hot wind can be discharged.
[0100] In addition, when the user selects at least one of the temperature adjusting and
selecting means, the time setting and selecting means, and the wind strength adjusting
and selecting means using the function selector 173, the controller 176 controls the
hair dryer 100 according to the user's selection, so that the hair dryer 100 operates
under the control of the controller 176.
[0101] As described above, since the hair dryer 100 includes the housing 111 and 115, the
air blower 120, the wind guide 160, and the rotor unit 140, air drawn from the outside
is guided in a predetermined direction while maintaining a concentrated state instead
of being dispersed. In this manner, the drawn air is converted into accelerated wind,
which is then discharged. The wind strength and flow rate performance of the hair
dryer 100 are improved, so that hair can be dried in a short period of time.
[0102] In addition, the heater 150 of the hair dryer 100 includes the electric heat generator
151, the upper heat dissipating member 145, the lower heat dissipating member 155,
and the heater connectors 152. The electric heat generator 151 is located in the inner
space defined by the upper heat dissipating member 145, the lower heat dissipating
member 155, and the heater connectors 152, so that fine dust and electromagnetic waves
generated by the electric heat generator 151 can be prevented from exiting outwards.
Mode for Invention
[0103] Hereinafter, hair dryers according to other embodiments of the present invention
will be described with reference to the drawings. In the following, descriptions of
some features will be omitted, when they are identical to those of the above-described
first embodiment of the present invention.
[0104] FIG. 11 is a front view illustrating a protrusion hood of a hair dryer according
to a second embodiment of the present invention, and FIG. 12 is a bottom perspective
view of the protrusion hood of the hair dryer according to the second embodiment of
the present invention.
[0105] Referring to FIGS. 11 and 12, according to the present embodiment, the hair dryer
includes a protrusion hood 201 including a protrusion hood body 202, a protrusion
hood cover 203, first hair pins 204, and second hair pins 205.
[0106] The protrusion hood body 202 is disposed on one end portion of the outlet. The protrusion
hood body 202 has a hollow portion extending through the interior thereof to communicate
with the inside of the housing member.
[0107] As illustrated in FIG. 11, the protrusion hood body 202 is shaped to conform to the
shape of a curved portion of the human body, e.g. the head of the human, for which
the hair dryer is used. Accordingly, the protrusion hood 201 can be brought adjacently
to the curved portion along the shape of the head, so as to dry the hair located in
a relatively wide area.
[0108] The protrusion hood cover 203 covers the front surface of the protrusion hood body
202. A plurality of wind holes 206 spaced apart from each other are provided in the
protrusion hood cover 203.
[0109] The plurality of wind holes 206 are arranged in the protrusion hood cover 203 in
the shape of the letter "V" and are spaced apart from each other. Accordingly, in
an area below the protrusion hood 201, the hair can be dried in a concentrated manner.
In an area above the protrusion hood 201, the hair in a relatively-wide area can be
dried.
[0110] The first hair pins 204 protrude perpendicularly from the front surface of the protrusion
hood cover 203 by a predetermined length.
[0111] The second hair pins 205 protrude perpendicularly from the front surface of the protrusion
hood cover 203 by a predetermined length. The second hair pins 205 are shorter than
the first hair pins 204.
[0112] Since the first hair pins 204 are in contact with the portion of the human body for
which the hair dryer is used, as described above, the predetermined distance between
the portion of the human body and the protrusion hood cover 203 may be maintained,
and the hair on the portion of the human body may be combed by the second hair pins
205.
[0113] In addition, while the hair is being dried, the portion of the human body, e.g. the
scalp, can be lightly tapped with the first hair pins 204, so that the scalp can be
provided with a massage effect.
[0114] FIG. 13 is a front view illustrating a hook hood of a hair dryer according to a third
embodiment of the present invention, and FIG. 14 is a top perspective view of the
hook hood of the hair dryer according to the third embodiment of the present invention.
[0115] Referring to FIGS. 13 and 14, according to the present embodiment, the hair dryer
includes a hook hood 301. The hook hood 301 includes a hook hood body 302, upper bars
303, upper hooks 304, lower bars 305, and lower hooks 306.
[0116] The hook hood body 302 is mounted on an end portion of the outlet. The hook hood
body 302 has a hollow portion extending through the interior thereof to communicate
with the inside of the housing member.
[0117] The upper bars 303 protrude from the front surface of the hook hood body 302 by a
predetermined length, at angles inclined in predetermined directions. The upper hooks
304 are bent from distal ends of the upper bars 303 in predetermined directions, so
as to be inclined at greater angles than the upper bars 303.
[0118] The lower bars 305 protrude from the front surface of the hook hood body 302 by a
predetermined length, in particular, from portions of the front surface spaced apart
from the upper bars 303, at angles inclined in predetermined directions. The lower
hooks 306 are bent from distal ends of the lower bars 305 to be inclined. The lower
hooks 306 are bent in the same direction as the upper hooks 304.
[0119] Since the upper bars 303 are longer than the lower bars 305, the hook hood body 302
can be brought adjacently to the portion for which the hair dryer is used, for example,
the curved portion along the shape of the head. Accordingly, the hair can be efficiently
combed.
[0120] The upper hooks 304 and the lower hooks 306 are bent in the same direction, but opposite
to the direction in which the hair hangs due to the weight thereof, so that the hook
hood 301 can be prevented from being caught by the hair or the surface of the head
while the hair is being combed.
[0121] When the hook hood 301 is configured as described above, the hair, growing on the
portion of the human body for which the hair dryer is used, may be combed by the upper
bars 303 and the lower bars 305. A portion of the hair is lifted up to a predetermined
height, caught by the upper hooks 304 and the lower books 306, so that the hair can
be combed without being tangled while the hair, as well as at least one of the portion
of the human body and the portion on which the hair is growing, is being dried.
[0122] In addition, since the hair is dried in a state in which the portion of the hair
is lifted up with the upper hooks 304 and the lower hooks 306, a variety of hair styles
can be produced.
[0123] FIG. 15 is a front partial cross-sectional view illustrating a noise reducing member
of a rotor unit of a hair dryer according to a fourth embodiment of the present invention.
[0124] Referring to FIG. 15, according to the present embodiment, a wind guide 460 of the
hair dryer includes an annular first mount 446 provided in a bottom portion of the
wind guide 460. A rotor unit 440 includes an annular second mount 448 provided on
a circumferential portion to correspond to the first mount 446. An elastic member
447 is located between the first mount 446 and the second mount 448. The elastic member
447 is repeatedly compressed or restored, in response to the operation of the rotor.
[0125] The first mount 446 may be connected to the wind guide 460 by means of assembly,
welding, etc., while the second mount 448 may be connected to the circumferential
portion of the rotor unit 440 by means of assembly, welding, etc.
[0126] The elastic member 447 may be a spring or the like. A plurality of the elastic members
447 may preferably be disposed between the first mount 446 and the second mount 448
to be spaced apart from each other, so as to simultaneously reduce the vibration of
the rotor unit 440.
[0127] Since the hair dryer includes the first mount 446, the second mount 448, and the
elastic member 447, the vibration and noise produced by the operation of the rotor
may be removed by the elastic force of the elastic member 447. Accordingly, the vibration
and noise produced by the rotor is prevented from being transferred to the wind guide
460.
[0128] In addition, according to the present embodiment, a vibration proof pad 449 may further
be provided between the wind guide 460 and the first mount, so that the vibration
of the rotor unit 440 can be double-prevented from being transferred to the wind guide
460.
[0129] While the present invention has been illustrated and described with respect to the
specific exemplary embodiments, it will be apparent to a person having ordinary skill
in the art that many modifications and variations are possible without departing from
spirit and scope of the present disclosure defined by the appended claims. It is definitely
noted that such modifications and variations are included within the scope of the
present disclosure.
Industrial Applicability
[0130] In the hair dryer according to an aspect of the present invention, electromagnetic

time. It is possible to block electromagnetic waves produced by the electric heat
generator surrounded by the upper heat dissipating member, the lower heat dissipating
member, and the heater connectors. Therefore, present invention is regarded as having

as to be inclined at greater angles than the upper bars;
lower bars protruding from the front surface of the hook hood body by a predetermined
length, in particular, from portions of the front surface spaced apart from the upper
bars, at angles inclined in predetermined directions; and
lower hooks bent from distal ends of the lower bars to be inclined in the same direction
as the upper hooks,
wherein hair, located on the portion of the human body for which the hair dryer is
used, is to be combed by the upper bars and the lower bars, and a portion of the hair
is lifted up to a predetermined height, caught by the upper hooks and the lower books,
so that the hair is to be combed without being tangled while the hair, as well as
at least one of the portion of the human body and the portion on which the hair is
located, is being dried.
11. The hair dryer according to claim 4, wherein the wind guide comprises an annular first
mount provided in a bottom portion thereof,
the rotor unit comprises an annular second mount provided on a circumferential portion
to correspond to the first mount, and
an elastic member is located between the first mount and the second mount, such that
the elastic member is repeatedly compressed or restored, in response to an operation
of the rotor,
wherein vibration and noise produced by the operation of the rotor is removed by elastic
force of the elastic member, so that the vibration and noise produced by the rotor
is prevented from being transferred to the wind guide.
