according to the present invention is characterized by that: [0032]
a housing enclosed by a peripheral frame and opened upward; [0033]
an insulating plate installed on the bottom of the housing; [0034]
a plate-type heater installed on the top side of the insulating
plate to be heated via applied electric power, said heater being

the outside of the same, air in the heat-transferring hole being
heated by transferred heat, and the heated air being discharged
from the hole to heat the inside of the rod for permanent wave
inserted into the heating rod.
[0038] In the present invention, a temperature sensor is installed
in the inside of at least one heating rod. The temperature sensor
is installed on the middle part of the heating rod in length
direction, and generates a signal for heating the
electrical-heating plate and the heating rod or stopping heating of
the electrical-heating plate and the heating rod according a set
temperature of the heating rod.
[0039] The heating rod formed with various lengths. The length can
be varied freely, preferably is not exceeded the length scope
disclosed in the present invention.
[0040] According to the present invention, a rod for permanent wave
is inserted into numbers of heating rods to be electrically heated,
said heating rod being fitted in an electrical-heating plate heated
by a surface of a heated plate-type heater to be heated from the
heated electrical-heating plate, wherein an electrical-heating tube
is formed in the rod for permanent wave with integral in length
direction, the inside of the electrical-heating tube is hollow and
an electrical blade is extended along the outside of the
electrical-heating tube.
[0041] Further, numbers of electrical-heating blades are formed
symmetrically about a concentric of the electrical-heating
tube.
[0042] Hereinafter, a preferred embodiment of the present invention
will be described in detail with reference to the accompanying
drawings. Throughout the drawings, same reference numbers are used
for functionally same parts or similar parts.
[0043] FIG. 1 is a perspective diagram which shows a heating device
for heating a rod for permanent wave according to the present
invention, FIG. 2 is an exploded perspective diagram which shows a
heating device for heating a rod for permanent wave according to
the present invention, and FIG. 3 shows a one embodiment of a
heating rod according to the present invention;
[0044] When referring FIGS. 1 to 3, a heating device 100 for
heating a rod for permanent wave according to the present invention
comprises a housing 10 enclosed by a peripheral frame 12 and opened
upward, an insulating plate 20 installed on the bottom 14 of the
housing 10, a plate-type heater 30 installed on the top side of the
insulating plate 20 to be heated via applied electric power, said
heater being installed between protecting plates 20, an
electrical-heating plate 40 electrically and directly heated from
the heated plate-type heater 30, and numbers of heating rods 50
fitted onto the electrical-heating plate 40 to be directly heated
from the plate-type heater 30, the heating rod being finished on a
surface identical with the lower side of the electrical-heating
plate.
[0045] The heating device 100 according to the present invention is
operated by supplying and stopping of electrical power. In one
embodiment of the present invention, the electrical power is
supplied to the heating device from a control block 110 via an
external line. The control block 110 is electrically connected to a
control panel 120.
[0046] The control block 110 supplies the electric power to the
plate-type heater 30 through controlling of the control panel 120
to perform heating caused by electric resistance.
[0047] In the present invention, the plate-type heater 30 can be
handled separately. As shown in one embodiment of the present
invention, for example, the plate-type heater may be wound by an
electrical-heating line 34 which is formed by a patterned a nickel
alloy resistor with a constant width, and may be protected by the
protecting plate 32 which is a sheet with an excellent thermal
resistance. As the plate-type heater 30 has a good thermal response
and a good softness, and can be close to a body to be heated, the
plate-type heater is suitable for a fine heating.
[0048] The heating device 100 according to the present invention is
spaced apart with constant distance from the control block 110
formed with bottom plate 130. The spaced apart heating device 100
is stacked on the inside of the housing 10 subsequently. The
housing 10 is enclosed by a peripheral frame 12 and is opened
upward. Meanwhile, a closed end forms a bottom surface 14 and is
flat.
[0049] The bottom surface 14 of the housing 10 is provided with the
insulating plate 20. Preferably, the insulating plate 20 is in
surface-contact with the bottom 14 of the housing 10 in order to
prevent heat of the plate-type heater 30 being transferred to the
outside of the housing 10.
[0050] At this time, a resistor 140 is installed on a side of the
housing 10 in order to protect the heating device 100 from
disconnection caused by over current or over heating.
[0051] The plate-type heater 30 is installed on the upper side of
the insulating plate 20 to be heated by applied electrical power.
As described above, the plate-type heater 30 is positioned between
the protecting plates 32. The protecting plate protects the
electrical-heating line 34 as a heating element.
[0052] The electrical-heating plate 40 is installed on a surface of
the plate-type heater 30. The electrical-heating plate is
positioned at a site from which an operator can be visible.
[0053] The electrical-heating plate 40 is directly heated from the
plate-type heater 30. The electrical-heating plate may be made of a
plate-type metal, and has a constant thickness.
[0054] The electrical-heating plate 40 is installed in the inside
of the housing 10, preferably inside of the peripheral frame 12.
The peripheral frame 12 defines the circumference of the
electrical-heating plate 40.
[0055] The electrical-heating plate 40 is provided with numbers of
passing-through holes 42. The passing-through hole are spaced apart
with a constant distance, and arranged regularly. A heating rod 50
is fitted into the passing-through hole 42.
[0056] Preferably, the heating rod 50 is finished at a surface
equal to the lower surface of the electrical-heating plate 40. By
such finish, the electrical-heating plate 40 presses the plate-type
heater 30 through its weight. Therefore, the heating rod 50 is
directly received the heat generated by the plate-type heater 30.
Further, the electrical-heating plate 40 and the housing 10 are
concretely connected to achieve the above-described object.
[0057] As one preferred embodiment, the heating rod 50 according to
the present invention is formed with numbers of electrical-heating
holes 52 on its surface, and the holes are passed through each
other.
[0058] When the heating rod is electrically heated, the
electrical-heating hole heats the air in the inside of the hole,
and discharges the heated air to the outside. At this time, the
discharged air is circulated repeatedly to heat the rod for
permanent wave 200 shown in FIG. 5, described lately.
[0059] Conventionally, an electrical-heating tube 210 is installed
in the rod for permanent wave 200, and the tube is electrically
heated by the heating rod 50 heated.
[0060] In the present invention, it is proper that the heating rod
50 can be embodied in various ways.
[0061] In the present invention, a temperature sensor 60 is
inserted in the inside of at least one of the heating rods 50 which
are fitted into the upper side of the electrical-heating plate 40.
The temperature sensor 60 senses a range of 120.about.160.degree.
C., and can be set to other temperature depending on the state of
operation.
[0062] In the present invention, the temperature sensor 60 is
installed on the middle part of the heating rod 50 in length
direction. The temperature sensor 60 can sense the heated state of
the heating rod 50 optimally. For example, the temperature sensor
60 conventionally installed on the lower side of the heating rod 50
or the electrical-heating plate 40 can be influenced by the
temperature of the heating rod 50 which heats the rod for permanent
wave 200. Therefore, the conventional temperature sensor 60 senses
sensitively the temperature of the electrical-heating plate 40 than
the temperature of the heating rod 50. That is, the conventional
temperature sensor 60 cannot sense the temperature of the heating
rod 50 exactly, as a temperature difference between the
electrical-heating plate 40 and the heating rod 50 is present.
[0063] Therefore, in the present invention, the temperature sensor
60 is installed in the inside of the heating rod 50, preferably on
the middle part in length direction. When the temperature sensor 60
detects the temperature of the heating rod and the temperature is
deviated from a set value, it is possible to maintain the state of
the rod for permanent wave 200 optimally by turning on or off the
electrical power to heat or cool the heating rod 50.
[0064] Again, as described above, the heating rod 50 according to
the present invention can be embodied by modifying the heating rod.
FIG. 4 shows other embodiment of the heating rod according to the
present invention. As shown in the drawing, the heating rod 50 can
be installed to have an optimal length for electrically heating the
rod for permanent wave 200. The preferable length is in the range
of 30 mm to 40 mm. The length is economical length.
[0065] The present invention further comprises the rod for
permanent wave 200 according to the present invention further
comprises.
[0066] The rod for permanent wave 200 according to the present
invention is structured as shown in FIGS. 5 and 6.
[0067] The rod for permanent wave 200 is inserted in the heating
rod 50 to be heated. Numbers of heating rods 50 are fitted into the
electrical-heating plate 40 to receive heat from the heated
electrical-heating plate 40 which is electrically heated by the
surface of the plate-type heater 30.
[0068] In the present invention, the term "length direction" means
a vertical length in which the heating rod 50 is installed, and the
center means the vertical center axis, in case of a circle, center
point.
[0069] The rod for permanent wave 200 according to the present
invention is integrally formed with an electrical-heating tube 210
which is hollow.
[0070] The electrical-heating tube 210 may be a conventional
aluminum tube, or made of other metal with high thermal
conductivity or nonmetal materials.
[0071] Unlike conventional electrical-heating tube, the
electrical-heating tube 210 according to the present invention is
integrally formed with an electrical-heating blade 212. Preferably,
the electrical-heating blade 212 is extended along the outer
surface of the electrical-heating tube 210 in length direction.
[0072] The electrical-heating blade 212 is inserted into the inside
of the rod for permanent wave 200 to be integral with the rod for
permanent wave which is made of synthetic resins.
[0073] By such construction, the temperature heated by the
electrical-heating tube 210 is transferred to the main body of the
rod for permanent wave 200 without loss, and can be maintained a
constant temperature when using.
[0074] Preferably, numbers of electrical-heating blades 212 are
symmetrically arranged for the center of concentric circle of the
electrical-heating tube 210.
[0075] By such construction, the electrical-heating blade 212
performs electrical-heating substantially as well as acts as
keeping warm. In addition, the main body is reinforced by the
electrical-heating blades 212.
[0076] And, the heating device 100 and the rod for permanent wave
200 described above can provide a permanent wave apparatus with
quickness, a good keeping warm efficiency and economical
efficiency.
[0077] In the present invention, various modifications can be
possible. For example, if necessary, the heating rod 50 having an
inclined outer surface and a flat upper end can be possible as
shown in FIG. 7. The inside of the rod for permanent wave 200
inserted in the heating rod 50 is inclined and has a shape
corresponding to the heating rod.
[0078] As shown in drawing, the heating rod 50 and the rod for
permanent wave 200 inserted into the heating rod are connected each
other via the inclined surfaces, and perform electrical-heating
through the inclined surfaces.
[0079] The inclined surface is directly in contact with the rod for
permanent wave to maximize the efficiency of electrical-heating,
and to perform electrical-heating quickly. In addition, the length
of the heating rod 50 is relatively shortened, and the material
used in making the heating rod is saved to accomplish economical
efficiency. Further, as shown in FIGS. 8 and 9, a separate
electrical-heating button 300 can be installed on the lower end of
the rod for permanent wave 200, and inserted into a cone-type
heating rod 50 to perform electrical-heating for the rod for
permanent wave 200 efficiently. As shown in drawings, the
electrical-heating button 300 has a fixing frame 310 which is
installed between the lower end outside and the lower end inside of
the rod for permanent wave 200, and an inclined frame 320 which is
directly heated by the heating rod 50.
[0080] The center of the inclined frame 320 is passed through, and
has a constant elasticity. The elasticity acts to contact the
inclined frame with the inclined surface of the heating rod 50
tightly and to fix the heating rod 50. That is, the situation that
the tight contact between the heating rod 50 and the inclined frame
320 performs quick electrical-heating can be included in the scope
of the present invention. Therefore, all of the variations or
modification included in the sprit and scope of the present
invention can be included in the claims appended.
[0081] While this invention has been described in connection with
what is presently considered to be the most practical and preferred
embodiment, it is to be understood that the invention is not
limited to the disclosed embodiments, but, on the contrary, is
intended to cover various modifications and equivalent arrangements
included within the spirit and scope of the appended claims.
[0082] As described above in detail, by a rod for permanent wave
and a heating device for electrically heating the rod with
efficiency according to the present invention, it is possible to
control an electrically heating temperature of the heating device
via an automatical intelligence control by a temperature sensor in
a heating rod. Therefore, it is possible to overcome the problem
caused from sensing of the temperature of the heating device and
inefficient electrical heating of the rod. Further, as it is
possible to electrically heat the heating rod via various shapes of
the heating rod, reliability of permanent works can be incredibly
increased.
