Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a hair dryer, and more particularly to a novel hair dryer that can effectively remove static electricity generated when, for example, hair is styled.

2. Description of the Related Art Hair dryers have traditionally been used in barber shops and beauty salons to dry and style hair.

When hair is dried and styled using a hair dryer, static electricity is generated due to friction.

The static electricity generated in the hair damages the dermal papilla and causes displacement of the skin tissue that is directly connected to the dermal papilla.

Therefore, if you repeat this kind of thing, it becomes easier to lose hair.

Furthermore, when such static electricity is generated, a so-called flying condition occurs in which the hair does not come together properly when styling the hair.

This is due to the repulsive effect of static electricity charged on the hair.

As mentioned above, static electricity generated in hair or artificial hair has various problems, and therefore it is necessary to prevent the generation of static electricity.

To this end, it has recently become common practice to use hair cosmetics such as lotions, hair creams, and hair nonces that contain surfactants that prevent static electricity.

However, such antistatic agents or surfactants must be used in consideration of the trouble they cause to hair and skin tissue.

Furthermore, if cosmetics are used to prevent the generation of static electricity, additional work such as drying is required, and as a result, it takes a long time to condition or style the hair.

Therefore, in this invention, when drying the hair (
To provide a completely new hair dryer that can effectively remove static electricity generated in artificial hair.

To summarize, this idea is to provide a high-voltage static elimination electrode near the outlet of a hair dryer, and when a high voltage is applied to it, a corona discharge is caused, and (g) and ←) generate approximately the same amount of ions.

The ions are blown by a fan to remove static electricity generated on hair or artificial hair and hair styling tools such as combs.

The above objects and other objects and features of the present invention will become more apparent from the following detailed description with reference to the drawings.

FIG. 1 is an illustrative view showing an embodiment of this invention.

In construction, the hair dryer 100 includes case parts 101 a and 101 that constitute a case 101 as is well known.

The case portion 101a acts as a gripping portion, and the case portion 101C acts as a tubular portion for blowing air.

Although not shown, a blower mechanism 104 consisting of a fan and a motor for rotating the fan is housed inside the case portion 101b.

The tip of the case portion 101C is configured as an air outlet, and a heater 105 for generating warm air or hot air is housed inside the case 101C.

Such a heater 105 may be composed of, for example, a heating wire or other heating element.

Further, a blower switch 102 and a hot air switch 103 are provided in the case portion 101a.

Note that a switch for switching between hot air and warm air, that is, switching the wattage of the heater, may be provided as necessary.

In addition, the tip of the case portion 101C, that is, the air outlet 109
has an adapter or nozzle 10 as an attachment.
7 can be added.

The structure and operation of such a hair dryer 100 are already well known, and detailed explanation thereof will be omitted here.

Below, the characteristic configuration of this invention will be explained in detail.

A feature of this invention is that the electrode section 200 is arranged near the air outlet inside the case section 101C, that is, the tubular section.

As can be easily seen from FIG. 2, which shows the part in a planar and enlarged view, this electrode section 200 consists of a high-voltage needle electrode 201 whose tip is oriented in the air blowing direction, and a high-voltage needle electrode 201 whose tip is oriented in the direction of air blowing. Electrode 20 arranged to face 201
2, the high voltage needle electrode 201 includes a mounting lug plate 201 a
The counter electrode 202 is supported by a similar mounting lug plate 202a.

These lug plates 201 a and 202 a are each
For example, it is attached to an electrode support base 203 made of heat-resistant synthetic resin (trade name: Teflon, etc.) using screws 204 and 205.

A high voltage lead wire 206a is electrically connected to this electrode 201, that is, the mounting lug plate 201a, and the electrode 201 is electrically connected to the mounting lug plate 201a.
2, that is, the high voltage lead wire 206 is attached to the mounting lug plate 202a.
b is electrically connected.

Such high voltage lead wires 206a and 206b are connected to case portions 101C, 101b, 101a, for example.
is placed in a groove 106 formed in the case portion 101a, and guided out along this groove 106 to the outside of the case portion 101a.

The high voltage lead wires 206a and 206b are connected to the power supply section 300 along with the power cords 108a and 108b.

Note that the case 101, that is, the case portion 101a.

101 b and 101 C can be made of synthetic resin or metal.

If this case 101 is made of metal, the electrode part 20
Particular attention should be paid to the withstand voltage of 0.

The power supply unit 300 connects a cord 400a from a commercial power source, for example.
and receives an alternating current (AC) 100 V power source through the 400 b.

The cords 400a and 400b are further connected to wires 301a and 301bK, and the wire 301a is connected to the primary winding 30 of the high voltage transformer 305 via a fuse 302.
5a, and wire 301b is connected to one end of power switch 3
03 to the other end of the primary winding 305a.

Further, both ends of this primary winding 305a are connected to wires 304, respectively.
Power cord 108a preceded by a and 304b
and 108b.

One end of the secondary winding 305b of the high voltage transformer 305 is connected to the previous high voltage lead wire 206a by a wire 306a, and the other end is connected to a current limiting resistor 307 having a relatively high value.
connected to one end of the

The other end of the current limiting resistor 307 is connected to the previous high voltage lead wire 206b by a wire 306b.

Furthermore, a current switch 308 is connected in parallel to both ends of the current limiting resistor 307 .

The power supply unit 300 has casters 309, 309...
is attached, and the structure is such that the flob can be moved freely.

The operation or operation of the above configuration will be explained below.

In operations, first, a case where the high-voltage needle electrode 201 of the electrode section 200 is mainly used as a static elimination electrode will be described.

At this time, first, the power switch 3 included in the power supply unit 300
Turn on 03.

Accordingly, for AC 100V power supply, use power cord 400A.

4b, the power cord 10 of the hair dryer 100
8a, 108b.

At this time, 100 V is also applied to the primary winding 305a of the high voltage transformer 305, and a high voltage of about 6000 V to 7000 V, for example, is generated in the secondary winding 305b.

Further, when the high-voltage needle electrode 201 is mainly used as a static elimination electrode, the current switch 308 is kept off.

Therefore, the high voltage generated in this secondary winding 305b is
06a to the high voltage lead wire 206b, and is applied to the high voltage lead wire 206b through the current limiting resistor 307 and the wire 306b.

Therefore, a relatively small current and high voltage is applied between the high voltage needle electrode 201 and the counter electrode 202 via the lines 206a and 206b.

Note that at this time, since this high voltage current is limited by the current limiting resistor 307, no discharge occurs between the voltage needle electrode 201 and the counter electrode 202.

According to experiments, the secondary winding 3 of the high voltage transformer 305
Experimental results show that when the output of 05b is set to about 7000 V, even at a distance of 70 cm from the air outlet 109 of the dryer 100, the static electricity that would have been generated at about 10000 V when this static elimination electrode was not provided becomes approximately 100 V or less. It has been obtained.

Next, when the voltage needle electrode 201 and the counter electrode 202 are used together as an electrode that also has an ozone generation effect, the current switch 308 is turned on.

Therefore, the current limiting resistor 307 is short-circuited, and a relatively large current and high voltage is applied between the high voltage lead wires 206a and 206b, that is, between the electrodes 201 and 202.

Therefore, the tip of this high voltage needle electrode 201 and the counter electrode 2
A strong corona discharge or spark discharge occurs between the tip of the 02 and the tip of the 02.

As a result, ozone (03) generation in this part becomes stronger.

This ozone has a strong oxidizing effect, which allows it to completely fix perming and coloring chemicals.

Therefore, an even and stable finish can be obtained without using a separate fixer.

Moreover, since the generated ozone is sent only to the necessary local areas, it is more effective than, for example, a dryer that covers the headstock, and the customer is less likely to feel uncomfortable due to ozone odor.

FIG. 3 is an illustrative diagram showing another type of dryer in which this invention can be implemented.

In this dryer, a power supply unit 300, a blower mechanism 104, a heater 105, etc., as shown in FIG. and the outlet 10 via the outlet pipe 112.
Sent on 9th.

The grip portion 111 is provided with two switches 102 and 103 (more switches if necessary) as shown in FIG. 1, for example.

An electrode section 200 as shown in FIG. 1 is provided in the vicinity of the blow-off port 109 in the blow-off vibrator 112.

The high voltage lead wire from this electrode section 200 is connected to the switch 10.
2, 103 and the necessary lead wires may pass through the inside of the hose 110 and be connected to the power supply unit 300.

Further, such high voltage lead wires or lead wires necessary for the switch may be integrally attached to the outside of the hose 110.

Of course, this type of dryer can also achieve the above-described effects of removing static electricity and producing ozone.

FIG. 4 is an illustrative view showing the main parts of another embodiment of this invention.

This embodiment has a brush portion 500 in which, for example, animal hair is implanted, particularly in the vicinity of the air outlet 109 provided in the case portion 101C.

This brush portion may be further converted into an attachment such as a comb or a clip pipe.

A plurality of the air outlets 109 are formed in a so-called slit shape in the length direction of the case portion 101C.

High-voltage needle electrodes for removing static electricity are provided close to some (all if necessary) of the plurality of air outlets 109, 109, . . . .

In this embodiment, the high-voltage needle electrodes 201 include a plurality (three) arranged in the length direction of the air outlet 109.

And these three high voltage needle electrodes 201.201.201
are connected by a connecting portion 201a.

Both ends of the connecting portion 201a are connected to the insulating support base 203° 203 provided on the case portion 101C.
It is attached to this case portion 101C in consideration of sufficient pressure resistance.

The connecting part 201a is further led to a power supply part 300 as shown in FIG. 1, for example, by a voltage lead wire 206a.

According to this embodiment, the action of the brush portion 500 allows static electricity to be removed while brushing.

FIG. 5 is an illustrative view showing the main parts of still another embodiment of this invention.

This embodiment is, for example, a permanent hair dryer and has a wind cap 601.

A hood 602 is attached to the lower end of this wind cap 601.

Furthermore, a partition plate 60 is inserted into the wind cap from the lower end of the wind cap 601.
4 is in the well-known format.

The partition plate 604 has a plurality of injection ports or air outlets 605°6.
05, . . . are formatted.

An air blowing mechanism 603 including a motor, fan, etc. (not shown) is housed in an internal space defined by the wind cap 601 and the partition plate 604.

A high voltage needle electrode 606 for removing static electricity is connected to the partition plate 6.
A plurality of air outlet ports 605 are provided corresponding to some (all of them if necessary) of the air outlet ports 605 formed in 04.

These plurality of high-voltage needle electrodes 606 are connected by a connecting part 606a and attached to the wind cap 601 with sufficient pressure resistance by an insulating support base 607.

This connecting portion 606a, that is, the high-voltage needle electrode 606 is led to, for example, a power supply section 300 as shown in FIG. 1 by a high-voltage lead wire 609 (corresponding to 206a in FIG. 1).

In this embodiment as well, the effect of removing static electricity can be obtained in exactly the same way.

In the embodiments shown in FIGS. 1 to 3 described above, the high-voltage needle electrode 201 and the counter electrode 202 facing it are provided, but this may be changed as needed in FIGS. 4 and 5.
It would also be possible to create a hair dryer that only has the effect of removing static electricity by simply providing the high-voltage needle electrode 201 as in the illustrated embodiment.

In addition, when the high-voltage needle electrode 201 is used as a static elimination electrode and is used as an electrode for ozone generation, the current limiting resistor 307 and current switch 308 are used because it is necessary to switch the current. Of course, it is also possible to use a current limiting impedance of .

Furthermore, it goes without saying that it is possible not only to simply switch the current, but also to change the applied voltage.

As described above, according to this invention, static electricity generated during hair drying or hair styling can be almost completely removed.

Therefore, there is no need to use antistatic agents or surfactants, which were conventionally required, and unique effects such as not damaging the hair and shortening the treatment time can be achieved.
