Description
BACKGROUND
[0001] The present invention relates to a hair iron, and more
particularly, to a hair iron heating upper and lower heating plates
through upper and lower heaters according to supplying of power to
style hair through a holding operation of the heated upper and
lower heating plates, in which the upper and lower heating plates
include iron removing members to attract and remove a foreign
substance such as iron attached to hair, thus preventing the damage
of hair due to a foreign substance and achieving efficient hair
styling, so as to satisfy customers or users.
[0002] Generally, hair irons are used in hairdressers' shops such
as beauty salons and barbershops to heat hair for hairdressing such
as waving, straightening, and curling. Such hair irons have been
developed in various shapes.
[0003] FIG. 1 is a perspective view illustrating a hair iron in the
related art. Referring to FIG. 1, an upper case 5 and a lower case
I are hinged to each other, and the lower case 1 includes a lower
grill part 2 handled by a hand, and a lower heating part 3 in a
single body through injection molding. The lower heating part 3
includes a built-in lower heater (not shown).
[0004] The front end of the lower case 1 is provided with a lower
heating plate 4 that is moved according to the amount of hair and
in surface contact with the hair to heat the hair. The upper case 5
is coupled with the lower case 1, and includes an upper grill part
6 and an upper heating part 7 in a single body through injection
molding. The upper heating part 7 includes a built-in upper heater
(not shown). The front end of the upper case 5 is provided with an
upper heating plate 8 that is moved according to the amount of hair
and in surface contact with the hair to heat the hair.
[0005] The upper and lower heating plates 8 and 4 may have various
shapes such as a flat plate shape, a triangular shape, a circular
shape, a semi-circular shape, and a combination thereof or have an
essentially .pi.-shaped cross-section. Hair is styled using the
hair iron by inserting a power plug connected to a power wire into
a plug receptacle, and then, by heating the upper and lower heaters
by the upper and lower heating plates 8 and 4, and simultaneously,
by sliding the upper and lower heating plates 8 and 4 on the hair
in the state where the hair is held by the upper and lower heating
plates 8 and 4, and, by applying heat generated from the upper and
lower heaters to the hair.
[0006] The upper and lower heating plates 8 and 4 typically include
rectangular heating parts, and the upper and lower heating plates 8
and 4 are fabricated by extruding aluminum (Al) or jade, and then,
by coating them with material such as Teflon coating material,
anodizing coating material, and ceramic coating material. In this
case, while the hair iron is used, foreign substances such as
various heavy metals attached from air to the hair iron are not
removed. Rather, the hair iron brings the foreign substances in
closer contact with the hair, thus damaging the hair.
[0007] On the other hand, various hair irons has been developed for
heath. Especially, a hair iron with magnets is disclosed in US
patent publication No. 2006/0207625. According to the US patent
publication, the magnets are disposed on corresponding styling
heads so that the magnetic polarity of the magnetic field appearing
on the pair of corresponding contact styling surfaces are the same,
the styling effects are better. Also, to further make use of the
advantage of magnetism on human boy, a negative magnetism or
negative magnetic polarity as known to therapeutic applications is
employed to appear on the contact styling surface. Because of like
magnetic polarity on the contact styling surface, the pair of
styling heads is repulsive to each other. However, in the US patent
publication, the magnets are not used to remove a foreign substance
from hair, but just used to implement well-known therapeutic
effects with the repulsion caused by the same magnetic
polarity.
[0008] Especially, when a foreign substance such as iron is
attached to hair, the foreign substance reacts with permanent wave
liquid or dye. This makes it difficult to perform desired
hairdressing and satisfy customers or users.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] Preferred embodiments of the present invention will be
described below in more detail with reference to the accompanying
drawings. The present invention may, however, be embodied in
different forms and should not be constructed as limited to the
embodiments set forth herein. Rather, these embodiments are
provided so that this disclosure will be thorough and complete, and
will fully convey the scope of the present invention to those
skilled in the art.
First Embodiment
[0029] FIG. 2A is a perspective view illustrating a hair iron
according to an embodiment of the present invention. FIG. 2B is a
schematic view including a plan view and a partial cross-sectional
view, which illustrates a lower heating plate of the hair iron of
FIG. 2A. Referring to FIGS. 2A and 2B, the hair iron according to
the current embodiment includes a lower case 10 and an upper case
20 hinged to the lower case 10.
[0030] The lower case 10 includes a lower grill part 12 and a lower
heating part 14 in a single body. The lower heating part 14
includes a built-in lower heater (not shown). A lower heating plate
16 is disposed at the front end of the lower case 10 to heat
hair.
[0031] The upper case 20 includes an upper grill part 22 and an
upper heating part 24 in a single body. The upper heating part 24
includes a built-in upper heater (not shown). An upper heating
plate 26 is disposed at the front end of the upper case 10 to heat

[0032] Surfaces of the upper and lower heating plates 26 and 16 are
coated with a mixed layer 70 that is formed by mixing one of Teflon
coating material, anodizing coating material, and ceramic coating
material, and an iron removing member. The iron removing member is
formed of a magnetic substance attracting and removing iron
attached to hair.
[0033] A mixing ratio of the coating material to the magnetic
substance may be an equal ratio, that is, 50:50. If the mixed
amount of the magnetic substance is less than the mixed amount of
the coating material, iron attracting performance may be degraded.
If the mixed amount of the magnetic substance is greater than the

[0047] In the hair iron configured as described above, the magnets
40 are attached to both sides of each of the upper and lower
heating plates 26 and 16 between the upper and lower heating plates
26 and 16. Thus, when the hair iron is used, and the upper and
lower heaters heat the upper and lower heating plates 26 and 16 to
hold and vary hair, the magnets 40 attract iron attached to the
hair. After the hair iron is used, the attracted iron is removed
from the upper and lower heating plates 26 and 16.
Fifth Embodiment
[0048] FIG. 6 is a plan view illustrating a state where a magnet is
attached between a plurality of lower heating plates of a hair iron
according to another embodiment of the present invention. Referring
to FIG. 6, the hair iron according to the current embodiment
includes the lower and upper cases 10 and 20 of the first
embodiment.
[0049] The upper and lower heating plates 26 and 16 each is
provided in duplicate, and the magnets 50 are attached between the
upper heating plates 26 and between the lower heating plates 16 to
attract and remove iron attached to hair. The magnets 50 may be
inserted in insertion recesses formed in the upper and lower
heating plates 26 and 16, or be formed through insert injection
molding, like in the forth embodiment.
[0050] In the hair iron configured as described above, the magnets
50 are attached between the upper heating plates 26 and between the
lower heating plates 16. Thus, when the hair iron is used, and the
upper and lower heaters heat the upper and lower heating plates 26
and 16 to hold and vary hair, the magnets 50 attract iron attached
to the hair. After the hair iron is used, the attracted iron is
removed from the upper and lower heating plates 26 and 16.
Sixth Embodiment
[0051] FIG. 7 is a perspective view illustrating a heating plate in
which magnets are inserted into both sides thereof according to
another embodiment of the present invention. Being different from
the above mentioned embodiments, in the current embodiment, the
magnets, preferably Sm-based magnets or SmCo-based magnets, are
inserted into, but not limited to, both sides of each of the upper
and lower heating plates 26 and 16. Tow circular grooves 70 are
formed at both sides of each of the upper and lower heating plates
26 and 16 and circular rods 71 are inserted into them. In this
embodiment, the magnets are installed at opposite side of an even
surface of each of the upper and lower heating plates 26 and 16
such that any damage is not caused on the surfaces of the heating
plates. Furthermore, the length of the rode 71 can be adjusted
based on the desired strength of the magnetic field.
[0052] According to the embodiments, the upper and lower heating
plates include the iron removing members to attract and remove
foreign substances such as iron attached to hair, thus preventing
the damage of hair due to foreign substances.
[0053] Since iron is removed from hair, the chemical reaction of
the iron with permanent wave liquid or dye can be prevented to
achieve efficient hair variations, thus satisfying customers or
users. Since a magnetic field pushes hair's moisture, hair dye can
be achieved fast and curling and straight of hair can be achieved
effectively. Moreover, since the magnets are positioned nearby hair
and head, the circulation of the blood is also promoted.
[0054] Although embodiments have been described with reference to a
number of illustrative embodiments thereof, it should be understood
that numerous other modifications and embodiments can be devised by
those skilled in the art that will fall within the spirit and scope
of the principles of this disclosure. More particularly, various
variations and modifications are possible in the component parts
and/or arrangements of the subject combination arrangement within
the scope of the disclosure, the drawings and the appended claims.
In addition to variations and modifications in the component parts
and/or arrangements, alternative uses will also be apparent to
those skilled in the art. For instance, the magnets can be formed
in the heating plates selectively. That is, the magnets can be
formed in both sides of the upper or lower heating plate or in one
side of the heating plate.
