central portion 220.
[0045] The first central portion 120 and the second central portion
220 may be brought into contact with each other in a state where
the first heating element 100 and the second heating element 200
are closed, and particularly, hair may be spread. That is, when the
hair is put between the first heating element 100 and the second
heating element 200, the first heating element 100 and the second
heating element 200 are closed to press the heating element 10 in
the combing direction M. The hair is ironed and spread by the heat
emitted from the first heating element 100 and the second heating
element 200 while the hair moves between the first central portion
120 and the second central portion. The combing direction (M) is a
direction opposite to the root direction of the hair, and can be
understood as a direction in which combing is performed. In FIG. 1,
the combing direction M is expressed as one specific direction, but
the other direction may be set to the combing direction M according
to the direction of the hair grip and the direction of the hair
root.
[0046] In the present embodiment, the first central portion 120 and
the second central portion 220 are formed in a flat plate shape,
and as another example, the first central portion 120 and the
second central portion 220 may be formed to include some curved
surfaces.
[0047] The comb protrusion 140 and the storage groove 240 may be
partially brought into contact with each other in a state where the
first heating element 100 and the second heating element 200 are
closed.
[0048] The first heating element 100 and the second heating element
200 are closed by pressing the upper and lower sides of the iron
body 10 with the hair placed between the first heating element 100
and the second heating element 200, The hair passes between the
first central portion 120 and the second central portion 220 and
passes between the comb protrusion 140 and the storage groove
portion 240, Various hair styling can be performed on the hair by
the heat radiated from the first heating element 100 and the second
heating element 200 and the curved shape of the comb protrusion 140
and the storage groove 240.
[0049] In addition, the comb teeth protrusion 142 disperses or
homogenizes the portion of the hair directly pressed by the first
and second heating elements 100 and 200 so that the user can easily
perform hair styling even with a small force, the effect of
reducing the damage of the hair is obtained at the same time.
[0050] The first heating element 100, the comb protrusion 140, the
second heating element, and the storage groove 240 may be made of
one material. As the material capable of transmitting heat, a high
temperature may be generated in a short time, and material can be
used as long as it is not deformed by the material, and can be made
of a metal material preferably electrically insulated.
[0051] As shown in FIG. 4, the comb teeth protrusion 142 may be
formed to have a slope 142b on both sides of the ridge 142a. The
inclined surface 142b allows the hair to be uniformly dispersed
along the inclined surface 142b and allows the heat provided by the
first and second heating elements 100 and 200 to be dispersed or
homogeneously distributed to the hair do.
[0052] The angle of inclination or the surface shape of the
inclined surface 142b of the comb teeth protrusion 142 can be
somewhat deformed in consideration of the machining aspect and the
like.
[0053] The protrusion receiving grooves 242 are formed to have a
groove shape corresponding to the shape of the comb teeth
protrusion 142, for example, uniform heat can be provided to the
hair by the projection receiving grooves 242.
[0054] The comb teeth protrusion 142 and the protrusion receiving
grooves 242 may be formed in the respective comb teeth protrusions
142 in the closed state of the first heating element 100 and the
second heating element 200 according to an embodiment of the
present invention, "a" is formed between the inclined surface 142b
of the protrusion 142 and the inner surface 242b of each protrusion
receiving groove for receiving the comb tooth protrusion 142.
[0055] Asian women have an average hair thickness of 0.08 to 0.1
mm, and Western women have hair thicknesses of about 0.05 mm,
compared to Asians. The size of the first gap (a) can be formed
such that about 3 to about 7 strands can be passed side by side on
the basis of, for example, the hair of an Oriental woman, and
preferably the first gap (a) may be formed to be 0.32 mm to 0.52
mm.
[0056] The first heating element 100 and the second heating element
200 are closed and the hair moves through the comb teeth protrusion
142 and the protrusion receiving groove 242 as the hair iron 10
moves, A plurality of hairs are positioned in the first gap a
formed between the inclined surface 142b of the protrusion
receiving groove and the inner surface 242b of the protrusion
receiving groove. The plurality of hairs may be heated by the first
and second heat generating bodies 100 and 200 while the first heat
emitting body 100 and the second heat emitting body 200 are closed
without exerting excessive pressure on the hair from both sides,
and a variety of hair styling can be performed while passing
between the comb protrusion 140 and the storage groove 240 without
a large resistance.
[0057] The first gap (a) minimizes the overpressure of the first
and second heating elements (100, 200) directly on the hair,
thereby preventing the cuticle of the hair from being broken due to
high temperature and high pressure. It is possible to reduce the
amount of water to be melted and removed.
[0058] The comb teeth protrusion 142 according to an embodiment of
the present invention is formed to have an inclined portion 142c
connecting the ridge 142a and the first center portion 120 along
the left and right direction.
[0059] In the closed state of the first heating element 100 and the
second heating element 200, the inclined portion 142c of each comb
protrusion 142 and the protrusions 142 of the respective
protrusions 142a second gap b is formed between the side surfaces
242c.
[0060] The second gap (b) temporarily dissolves the pressure and
the high temperature directly applied to the hair passing between
the first center portion 120 and the second center portion 220
while the second gap (b) is similar to the first gap a thereby
minimizing the destruction of the cuticle. According to an
embodiment of the present invention, the size of the second gap (b)
may be about 3 to 7 strands so as to be parallel to each other when
the oriental female hair is used as a reference, preferably 0.33 mm
to 0.53 mm.
[0061] In FIGS. 5 and 6, the curved shape formed by the first and
second central portions 120 and 220 and the inner side surface 242c
of the projection receiving groove is formed by the comb tooth
projection 142 and the projection storage groove. A variety of hair
styling can be performed on the hair in addition to the curved
shape formed by the hair 242.
[0062] The shape of the first and second center portions 120 and
220 and the curved shape formed by the first and second central
portions and the inner side surface 242c of the projection
receiving groove and the shape of the comb tooth projection 142 and
the projection receiving groove 242. It is possible to give a
straight or various kinds of curls to the hair by merely adjusting
the rotation angle [alpha] of the ironing iron according to an
embodiment of the present invention and combing in the combing
direction M.
[0063] For example, the straightness of the hair may be determined
in a state where the rotation angle [alpha] is 0 with respect to
the plate-like surfaces of the first central portion 120 and the
second central portion 220, can be accomplished by moving the hair
iron in the combing direction (M).
[0064] As another example, a curl of hair may be formed in a state
where the rotation angle [alpha] is not 0 based on the plate-like
surfaces of the first central portion 120 and the second central
portion 220, rotation can be accomplished by moving the hair iron
in the combing direction (M).
[0065] The shape of the curl can be expressed differently according
to the magnitude of the rotation angle [alpha], and the strong curl
can be achieved as the rotation angle [alpha] is larger.
[0066] For example, C-curl at about 45.degree., J-curl at about
90.degree., and S-curl at about 180.degree. may be formed at a
rotation angle .alpha. of about 45.degree., The shape of the
bending structure formed by the inner side surface 242c of the
projection receiving groove and the shape of the comb tooth
projection 142 and the projection receiving groove 242 can be
changed.
[0067] Particularly, when the upper and lower portions of the iron
plate are used upside down, for example, when the first heat
generating element is positioned so as to be upward, even if the
same rotation angle is given, a strong curl forming effect can be
obtained.
[0068] The first heating element 100 according to the embodiment of
the present invention is curved in the direction in which the left
and right ends are away from the corresponding ends of the second
heating element 200. FIGS. 5 and 6, the second heating element 200
is curved in a direction opposite to the position of the second
heating element 200 that is, in a direction opposite to the
position of the second heating element 200 and is formed to have a
shape to surround a part thereof.
[0069] The second heating element 200 is formed to surround a part
of the first heating element 100 and the first gap (a) and/or the
second gap (b) are formed, when the two heat generating elements
100 and 200 evaporate, the entire amount is not discharged to the
outside but a substantial amount can be present inside. Damage to
the hair due to heat at a high temperature can be reduced due to
moisture in the form of vapor present between the first heating
element 100 and the second heating element 200.
[0070] The comb teeth protrusions 142 may be curved in such a
manner that their outer ends (both ends of the left and right
sides) are lowered when the ends of the first heating element 100
are curved, curling can be performed more easily by curving
formation in which the outer end of the comb tooth protrusion 142
is lowered when the curl is formed.
[0071] The maximum projecting height (h) of the comb teeth
protrusion 142 according to an embodiment of the present invention
is preferably 2.4 mm to 2.6 mm.
[0072] When the maximum projecting height of the comb teeth
protrusion 142 is larger than the above range, the hair is placed
between the first heating element 100 and the second heating
element 200 and the first heating element 100 and the second
heating element 200 in the closed state, more force is required to
move the ironing unit 10 in the lateral direction.
[0073] In addition, when the maximum projecting height of the comb
teeth protrusion 142 is smaller than the above range, the curling
effect on the hair may be lowered.
[0074] The center distance (p) between each of the comb teeth
protrusions 142 according to an embodiment of the present invention
is formed to be 3.5 mm to 4.5 mm.
[0075] When the center distance between the comb teeth protrusions
142 is too short, the tension is increased during the straight
operation, so that more force is required to move the iron body 10
in the left and right direction, and the center distance between
the comb teeth protrusions 142 is too long the effect of curling on
the hair may be lowered.
[0076] The comb teeth protrusion 142 may be formed so that the
cross-sectional area of the comb tooth protrusion decreases from
the inner end portion to the outer end portion of the comb tooth
protrusion 142. In this case, the hair positioned can be easily
discharged from the hair iron 10 when the hair iron 10 is moved in
the combing direction M.
[0077] The first heat generating body 100 and the second heat
generating body 200 may have a first heat generating body coupling
part 150 and a second heat generating body coupling part 250. The
first and second heat generating body coupling parts 150, the first
and second heating elements 100 and 200 can be firmly coupled to
the hair iron 10 by being slidably coupled to a body coupling
portion (not shown) formed on the hair iron 10.
[0078] The first heating element 100 and the second heating element
200 may be provided with electric heating parts (e.g., coils) on
the outside of the first heating element 100 and the second heating
element 200, respectively.
[0079] While the present invention has been particularly shown and
described with reference to exemplary embodiments thereof, it is
evident that many alternatives, modifications and variations will
be apparent to those skilled in the art without departing from the
scope of the invention. Accordingly, the scope of the invention
should be construed as being limited by the scope of the claims set
forth as including many such variations.
