Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a hair dryer, and more
particularly, to a hair dryer that is equipped with a container
storing water or hair tonic, and is capable of ejecting the water
or the hair tonic to the hair when used, to thereby protect the
hair.
[0003] 2. Description of the Related Art
[0004] Generally, a hair dryer is used to dry hair after shampooing
or for hairstyling.
[0005] As shown in FIG. 1, a typical hair dryer includes a main
body 10 and a handle 60.
[0006] The main body 10 accommodates a fan 20 at an inner rear
portion, a motor 30 provided in front of the fan 20 to drive the
fan 20, and a heater 40 provided in front of the motor 30.
[0007] The handle 60 is provided with a button 70.
[0008] If the button 70 provided at the handle 60 is pushed, the
heater 40 emits heat, and the fan 20 is driven to eject the hot air
through openings 50 formed at the main body 10 to dry or style
hair.
[0009] However, when using the hair dryer for a long time or long
period, hair is damaged by the heat.
[0010] To protect the hair from heat, hair dryers capable of
supplying water or hair tonic to the hair have been devised.
[0011] For instance, there is a heating type hair dryer (refer to
FIG. 2) and a convection type hair dryer (refer to FIG. 3).
[0012] As shown in FIG. 2, the heating type hair dryer includes a
water container 80 storing water, a first heater 40 for heating
air, and a second heater 40' for heating the water stored in the
water container 80. The water heated by the heater 40' is
evaporated, and steam is ejected through the openings 50 formed at
the main body 10.
[0013] However, the heating type hair dryer has the problem that
the main body 10 is heated by the heater 40' and a user may get
burnt.
[0014] Also, unless a fiber member provided at a contact portion
between the heater and the water container gets wet, steam cannot
be generated.
[0015] In other words, if the hair dryer is not used for a long
period, the fiber member gets useless by being dried and
carbonized.
[0016] As shown in FIG. 3, the convection type hair dryer includes
a container 80 storing hair tonic, and a discharge part 90 for
discharging the hair tonic from the container 80. When the hair
dryer operates, the hair tonic exhausted from the container 80 is
ejected through the openings 50 with air blown from the fan 20.
[0017] However, the convection type hair dryer has the problem that
the ejecting amount of hair tonic is too small to achieve the hair
protecting effect, and it has a large-sized structure.
[0018] Also, the hair tonic with high viscosity is not ejected
well.
[0019] If the diameter of the discharge part is enlarged to
increase the ejecting amount of hair tonic, the hair tonic may leak
outside in a non-used state and cause an electric shock when using
the hair dryer.
SUMMARY OF THE INVENTION
[0020] Therefore, the present invention has been made in view of
the above problems, and it is an object of the present invention to
provide a hair dryer that is equipped with a container storing
water or hair tonic, and is capable of ejecting the water or the
hair tonic to the hair when used, to thereby protect the hair.
[0021] In accordance with an aspect of the present invention, the
above and other objects can be accomplished by the provision of a
hair dryer including a main body which accommodates a fan, a motor
and a heater, and a handle which extends downward from the main
body and is provided with a button, comprising a nozzle which is
coupled to the main body and contains water or hair tonic.
[0022] The nozzle includes a body, a receiving part, and a
containing part.
[0023] The containing part includes a container which contains
water or hair tonic, and a cover which is made of a porous metal
material and formed at the container by insert injection
molding.
[0024] The nozzle further includes an evaporation filter which is
provided on a front surface of the cover. The evaporation filter
absorbs a substance contained in the container and evaporates the
substance to decrease a particle size of the substance and easily
supply the substance to the hair.
[0025] In accordance with another aspect of the present invention,
there is provided a hair dryer comprising: a main body which
accommodates a fan and a heater; a receiving part which is provided
on the main body; and a containing part which is received in the
receiving part, the containing part including a container which
contains water or hair tonic, a cover which is made of a porous
metal material, an evaporation filter, and a straw which houses the
cover and the evaporation filter. If air heated by the heater heats
the straw when discharged outside by the fan, heat is transferred
to the container, and a substance contained in the container
expands and leaves the containing part, and is ejected with air to
be supplied to the hair.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0035] Now, preferred embodiments of the present invention will be
described in detail with reference to the annexed drawings.
[0036] FIGS. 4 to 6 are an exploded perspective view, a perspective
view, and a sectional view, respectively, illustrating a hair dryer
in accordance with a first exemplary embodiment of the present
invention.
[0037] The hair dryer according to the present invention comprises
a main body 100, a handle 600, and a nozzle 800 in which water or
hair tonic is contained.
[0038] The main body 100 accommodates a fan 200, a motor 300, and a
heater 400.
[0039] The fan 200 is disposed at an inner rear portion of the main
body 100, and the motor 300 is disposed in front of the fan 200 to
drive the fan 200.
[0040] If a button 700 provided at the handle 600 (which will be
described later) is pushed, the fan 200 is applied with power and
rotates.
[0041] When receiving power, the heater 400 heats air and the
nozzle 800, so that the water or the hair tonic contained in the
nozzle 800 expands and is ejected outside.
[0042] The handle 600 extends downward from a portion of the main
body 100, and is provided with the button 700.
[0043] If the button 700 provided at the handle 600 is pushed, the
motor 300 is driven to rotate the fan 200, and the heater 400 is
driven to heat air blown from the fan 200 toward openings 500.
[0044] The nozzle 800, in which the water or the hair tonic is
contained, is coupled to a front end of the main body 100 where the
openings 500 are formed.
[0045] The nozzle 800 includes a body 801, a containing part 810 in
which the water or the hair tonic is contained, and a receiving
part 803 in which the containing part 810 is received.
[0046] The body 801 of the nozzle 800 is coupled to the front end
of the main body 100 where the openings 500 are formed. The body
801 of the nozzle 800 is shaped such that a cross-sectional area
increases as it progresses forward.
[0047] The receiving part 803 is disposed inside the body 801, and
the containing part 810 is received in the receiving part 803.
[0048] The containing part 810 includes a container 811 in which
the water or the hair tonic is contained, and a cover 813 which
covers the container 811.
[0049] It is preferred that the container 811 is made of a material
having a high heat conductivity, such as plastic, aluminum, or
copper, in order to effectively transfer heat to the substance (the
water or the hair tonic) contained in the container 811 when the
container 811 is heated. The cover 813 covering the container 811
is formed at an opening of the container 811 by insert injection
molding.
[0050] The cover 813 is made of a porous metal material. The cover
813 restricts the evaporation of the substance (the water or the
hair tonic) in a natural condition, and allows the expanded
substance by heating the container 811 using the heater to be
ejected from the container 811.
[0051] The containing part 810 is received in the receiving part
803 while the cover 813 is directed forward of the hair dryer.
[0052] FIG. 7 is a sectional view illustrating a hair dryer in
accordance with a second exemplary embodiment of the present
invention.
[0053] The hair dryer of this embodiment is configured such that
the containing part 810 is received in the receiving part 803 while
the cover 813 is directed toward the main body 100. An evaporation
filter 900 is provided on a front surface of the cover 813.
[0054] When the substance contained in the container 811 expands by
the air heated by the heater 400 and is ejected through the cover
813, the evaporation filter 900 absorbs the substance. The
substance absorbed in the evaporation filter 900 is evaporated and
ejected outside with the air blown from the fan 200. By such an
evaporation filter 900, the particle size of the substance becomes
so small as to be easily applied to the hair.
[0055] FIG. 8 is a sectional view illustrating a hair dryer in
accordance with a third exemplary embodiment of the present
invention.
[0056] The hair dryer of this embodiment is configured such that
the receiving part 803 is provided on the main body 100, in which
the container 811 of the containing part 810 is received. The
containing part 810 includes the cover 813 made of a porous metal
material, and the evaporation filter 900. The cover 813 and the
evaporation filter 900 are housed in a straw 1000 that is made of a
material having a high heat conductivity.
[0057] If the air heated by the heater 400 heats the straw 1000
when discharged outside by the fan 200, the heat is transferred to
the containing part 810. The substance contained in the containing
part 810 expands and leaves the containing part 810, and is ejected
with the air through the openings of the hair dryer to be supplied
to the hair.
[0058] Hereinafter, the operation of the hair dryer according to
the first embodiment of the present invention will be
described.
[0059] Referring to FIG. 6, if the button 700 provided at the
handle 600 is pushed, the motor 300 is driven to rotate the fan 200
and the heater 400 emits heat.
[0060] The fan 200 rotating by the motor 300 blows the air toward
the openings 500, and the air is heated by the heater 400 while
passing by the heater 400.
[0061] While passing through the openings 500, the heated air heats
the water or the hair tonic contained in the containing part 810
received in the receiving part 803 of the nozzle 800 which is
coupled to the front end of the main body 100 where the openings
500 are formed.
[0062] The water or the hair tonic contained in the containing part
810, that is heated by the air, expands in the container 811, and
is exhausted from the container 811 through the cover 813 of a
porous metal material which is attached to the container 811.
[0063] The water or the hair tonic exhausted from the container 811
is ejected outside with the air blown from the fan 200 and passing
through the openings 500, and supplied to the hair, so as to
protect the hair when drying the hair after shampooing or
hairstyling.
[0064] The operation of the hair dryer according to the second
embodiment of the present invention will now be described.
[0065] Referring to FIG. 7, if the button 700 provided at the
handle 600 is pushed, the motor 300 is driven to rotate the fan 200
and the heater 400 emits heat.
[0066] The fan 200 rotating by the motor 300 blows the air toward
the openings 500, and the air is heated by the heater 400 while
passing by the heater 400.
[0067] While passing through the openings 500, the heated air heats
the water or the hair tonic contained in the containing part 810
received in the receiving part 803 of the nozzle 800, which is
coupled to the front end of the main body 100 where the openings
500 are formed.
[0068] The water or the hair tonic contained in the containing part
810, that is heated by the air, expands in the container 811, and
is exhausted from the container 811 through the cover 813 of a
porous metal material which is attached to the container 811. The
water or the hair tonic exhausted through the cover 813 is absorbed
in the evaporation filter 900 provided on the outer surface of the
cover 813, and then evaporated.
[0069] The water or the hair tonic exhausted from the container 811
and evaporated by the evaporation filter 900 is ejected outside
with the air blown from the fan 200 and passing through the
openings 500, and is supplied to the hair, so as to protect the
hair when drying the hair after shampooing or hairstyling.
[0070] The operation of the hair dryer according to the third
embodiment of the present invention will now be described.
[0071] Referring to FIG. 8, if the button 700 provided at the
handle 600 is pushed, the motor 300 is driven to rotate the fan 200
and the heater 400 emits heat.
[0072] If the air heated by the heater 400 heats the straw 1000
when discharged outside by the fan 200, the heat is transferred to
the containing part 810. The substance contained in the containing
part 810 expands and leaves the containing part 810, and is ejected
with the air through the openings of the hair dryer to be supplied
to the hair.
[0073] As apparent from the above description, the hair dryer
according to the present invention is equipped with the container
storing the water or the hair tonic, and is capable of ejecting the
water or the hair tonic to the hair when used, thereby protecting
the hair.
[0074] Although the preferred embodiments of the present invention
have been disclosed for illustrative purposes, those skilled in the
art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying
claims.
