Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to far infrared ray hair
dryer, and particularly, to a hair dryer which has a porous ceramic
honey comb heater capable of emitting a far infrared ray out of its
housing so as to dry the user's hair without hurting his/her
hair.
[0003] 2. Description of the Prior Art
[0004] The most essential purpose of a conventional hair dryer is
to generate high temperature wind so as to dry the user's hairs
efficiently. Its typical structure is shown as FIG. 1. A tubular
housing 10 has a wind exit 11 at one end, and an air inlet 13
covered with a filter net 12 at the other end. A fan motor 14 is
equipped in the housing 10 near the air inlet 13 so as to draw in,
and discharge the air out of the housing 10. A resistance coil unit
is fastened around the inner edge of the housing at wind exit side
to work as a heat generating unit 16 operable according to
switching of a control switch 18 installed on the hand grip 17 and
electrically connected to the heat generating unit 16 so as to
output desired hot or cold wind with various intensity.
[0005] Actually, the aforesaid hair dryer is a high heat
consumption electrical appliance simply containing a heater coil
inside. In spite of the fact that it is able to adjust the wind
temperature, wind intensity and operating time at ones will,
unexpectable overheating happens quite often which results in
severe damage to the user's hair.
[0006] Incidentally, a conventional hair dryer often involves some
unpleasant defects such as: 1. Hurting the user's hair, 2. bringing
ret hot feeling to the user's head, 3. producing scorching oder,
and 4. causing dizziness and headache to the user.
[0007] Other uncertain worries are: 1. radiation of extremely
intensive electro-magnetic wave which is more than 20 times that a
cellular phone generates, 2. significant tendency that beauticians
and barbers prone to suffering from cataract, 3. teenagers' blood
poisoning, 4. dizziness or weak-minded.
[0008] According to WHO Annual Report of 2001, the teenagers
younger than 16 ages who are frequently exposed to radiation of
electro-magnetic wave are prone to suffering from blood cancer with
a probability 2.8 times than those who have never exposed under
radiation of said wave. The US NIEHS, EPA organizations have
tentatively established the maximum allowable value of the
intensity of electro-magnetic wave as 2.0 gausses after nine year
study spending US$65,000,000.
[0009] In view of the noticeable problems inherent to the
conventional ohmic heat coil type hair dryer which should be
overcome for the sake of the human health, the inventor has
dedicated great efforts for years to studying and improving these
defects and finally come up with this invention.
SUMMARY OF THE INVENTION
[0010] The main object of this invention is to provide a far
infrared ray hair dryer which has a porous ceramic honey comb
heater equipped in the front end of the housing near the wind exit
to radiate far infrared ray after being heated. This far infrared
ray wave is never hurt the human hair due to overheating, and this
porous ceramic honey comb heater further can maintain a stable
heating temperature, can be operated securely, and fabricated with
a low cost.
[0011] The above object and other advantages of the present
invention will become more apparent by describing in detail the
preferred embodiment of the present invention with reference to the
attached drawings.

[0012] For fuller understanding of the nature and objects of the

dryer.
[0014] FIG. 2 is a perspective view of the present invention.
[0015] FIG. 3 is a sectional view of the present invention.
[0016] FIG. 4 is a three dimensional view of the porous ceramic

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] Referring to FIGS. 2 and 3, the hair dryer according to the
present invention has a hollow tubular housing 2 including an air
inlet 21, a fan motor 22, a bracket 23 with a porous ceramic honey
comb heater 4 equipped on its front end, and a wind exit 24. The
one end of the heater element 4 is connected to a circuit board
(not shown) with a heater coil 40. As soon as the circuit is
switched on and the comb heater 4 is heated by the heater coil 40
so as to radiate a far infrared ray, the hot or cold wind is blown
out of the wind exit 24 together with the far infrared ray by the
fan motor 22.
[0022] The porous ceramic honey comb heater 4 is fixed on the
bracket 23 with a metal ring (not shown) to which an electrode is
attached to energize the metal ring. The honey comb heater 4 is
then adhered around the outer side of the metal ring and the two
ends of the heater element 4 are coated with an electrically
conducting silica gel so that it can generate heat by introducing
current from the metal ring. With this mechanism the porous ceramic
honey comb heater 4 is heated up to a predetermined temperature so
as to radiate a large amount of far infrared ray.
[0023] Alternatively, the honey comb heater 4 may be assembled to
the metal ring of the bracket 23 with its outer edge, and connected
to a metal ring at the other end, by so the ceramic honey comb
heater 4 is sandwiched therebetween and allows the current to flow
therethrough with the two metal rings serving as a couple of
electrodes.
[0024] The porous ceramic honey comb heater 4 is a nano high
technologic product fabricated by sintering process; it is able to
radiate a far infrared ray with low power consumption yet a heat
transformation rate as high as 95%.
[0025] The internal circuit of the hair dryer is controlled by a
control switch provided on a side of the hand grip so that cold or
wet wind can be outputted at different speeds as the user
desires.
[0026] The ceramic heater 4 has an extra function to reduce the
voltage rise so as to minimize the noise of the fan motor 22 when
it rotates. The beehive configuration of the heater 4 is also
possible to minimize its volume that leads to reduce the overall
size of the hair dryer.
[0027] As shown in FIG. 4, the porous ceramic honey comb heater 4
is integrally molded with material consisting of far infrared ray
radiating substance and has proper number of axially laid square
through holes 41 whose fillets are obtusely shaped so as to prevent
creating acute portion inside the through holes 41 thereby
increasing the mechanical strength of the structure. The entire
structure of the ceramic honey comb heater 4 is further bound by a
hoop 43 tightly to the bracket 23. Alternatively, the through holes
44 may be formed into a beehive type.
[0028] The operational principle of the present invention can be
understood with reference to FIG. 6. In FIG. 6; sub-drawing(A)
shows a water molecule w sticking to a hair molecule H;
sub-drawing(B) shows the water molecule W is mingled with the hair
molecule H; sub-drawing(C) shows water molecules W are scattered by
radiation of the far infrared ray C; sub-drawing(D) shows the water
molecules W scattered by far infrared ray C are more mingling with
the hair molecules; and sub-drawing(E) shows the hair is now
restored its brilliance and vividness.
[0029] The far infrared ray radiated by the ceramic honey comb
heater 4 includes characteristic data as follows:
[0030] 1. Extremely low electro-magnetic wave intensity below 2
gausses;
[0031] 2. Wave length of the far infrared ray: 9 .mu.m;
[0032] 3. High electrical efficiency: 33%
[0033] 4. Negative ion creation: 5,000,000
[0034] 5. No red hot feeling;
[0035] 6. Never scorching the hair;
[0036] 7. High hair drying speed.
[0037] The comparison of characteristics between the present
invention and the conventional hair dryer is concluded in FIG. 7,
and the comparison of electrical efficiency between is express by
graphs in FIG. 8. Apparently the ceramic honey comb heater can
radiate effectively far infrared ray to dry the user's hair
effectively without any worry of possible damages, and the hair
dryer can be fabricated easily, simply with a low cost. It is
really a practical product.
[0038] Those who are skilled in the art will readily perceive how
to modify the invention. Therefore, the appended claims are to be
construed to cover all equivalent structures which fall within the
true scope and spirit of the invention.
