plate portions

22 and 32 are configured by the hair sandwiching

side plates

22b and 32b and the

back side plates

22c and 32c, and the hair sandwiching

side plates

22b and 32b and the

back side plates

22c and 32c are used. The formed space is the

accommodating portion

24, 34. The heaters 23 and the heaters 33 housed in the housing portion 24 and the housing portion 34 are in contact with the inner surfaces of the plate portion 22 and the plate portion 32, respectively.

The plate portion 22 and the plate portion 32 are preferably made of, for example, a material having high thermal conductivity such as copper or aluminum so that heat can be easily transmitted to the hair.

Further, in the present embodiment, a PTC heater (Positive Temperature Coefficient heater) is used as the heater 23 and the heater 33, which enables continuous temperature control. Although the heater 23 and the heater 33 use a PTC heater as an example in the present embodiment, the present invention is not limited to this, and a nichrome wire heater or other heating means may be used. In addition, the heater (heat generating unit) may be provided only in one of the upper holding unit (first holding unit) 2b and the lower holding unit (second holding unit) 3b.

A plurality of ion generators 10 are provided in the inside of the sandwiching portion (second sandwiching portion 3 b) of the case 30. In the present embodiment, four ion generators 10 are provided along the longitudinal direction at both widthwise end portions of the second sandwiching portion 3b. As this ion generator 10, a mist generator that generates mist or a metal particle generator that generates metal particles can be used. And the discharge port 30e which the ion (mist and metal particulates) produced | generated by this ion generator (mist generator and metal particulate generator) respectively opened to the upper end part of lower case 30b outward and diagonally upward It is released from the Thus, ions (mist or metal particles) are efficiently supplied to the hair sandwiched between the upper hair holding surface 22a and the lower hair holding surface 32a by releasing the ions (mist or metal particles) from the outlet 30e. I am able to do it.

As a mist generating device, a device for applying high voltage to the discharge electrode 11 from the high voltage generation circuit with reference to the ground electrode 12 to generate discharge (such as corona discharge) and atomizing dew condensation water by the discharge action It can be used. By using this device to atomize dew condensation water by a discharge action, it is possible to generate a very fine mist of a nanometer size (minusly charged mist including negative ions).

And as what generates dew condensation water, it has a cooling plate which consists of a member (for example, metal member etc.) which has a Peltier element and heat conductivity, and a radiating fin which radiates away the heat generated at the time of cooling a cooling plate. A well-known thing can be used.

In addition, as the metal particle generation device, a device that generates a discharge (such as corona discharge) by applying a high voltage to the discharge electrode 11 from the high voltage generation circuit with reference to the ground electrode 12 can be used. By using this device to generate discharge (such as corona discharge), metal particles (such as metal molecules and ions) can be released from the discharge electrode, the ground electrode, and the like.

A well-known thing can also be used as such a metal microparticle generator. For example, the discharge electrode 11 of the metal particle generator is plated with a transition metal (eg, gold, silver, copper, platinum, zinc, titanium, rhodium, palladium, iridium, ruthenium, osmium, etc.) alone, an alloy, or a transition metal. It is possible to comprise by the processed member etc.

Here, when gold, silver, copper, zinc or the like is contained in the metal fine particles generated and released in the discharge portion, the antibacterial action can be generated by the metal fine particles. When platinum, zinc, titanium or the like is contained in the fine particles of metal, the fine particles of the metal can produce an antioxidant effect. In addition, it is known that fine particles of platinum have a very high antioxidative effect. Further, a portion (for example, a ground electrode or the like) which does not release the metal fine particles can be configured using stainless steel, tungsten, or the like.

In addition, the discharge unit generates ions (for example, negative ions, for example, NO2-, NO3-, etc.) by a discharge action, and this ion is used as a discharge electrode, a ground electrode, a member containing other metal materials or metal components, The metal particles may be generated by collision. That is, the ground electrode or the other member may be made of the material containing the transition metal, and metal fine particles may be released therefrom.

Further, a control circuit 6a for controlling the temperature of the heater 23 and the heater 33 is accommodated in the case 30, and the heater 23 and the heater 33 are connected to the control circuit 6a through the lead wire 8. . In the present embodiment, the temperatures of the upper hair pinching surface 22a and the lower hair pinching surface 32a can be set stepwise. Further, a power cord (not shown) is pulled out from the rear end portion 1 a of the hair iron 1.

Then, the operation switch 7 is provided on the lower grip 3 a side of the case 30. By operating the operation switch 7, it is possible to switch on / off of the current supply to the heater 23 and the heater 33. It has become. When the heater 23 and the heater 33 are energized by the operation of the operation switch 7, the heater 23 and the heater 33 generate heat. Then, the heat is transmitted from the heater 23 and the heater 33 which generate heat to the plate portion 22 and the plate portion 32, whereby the plate portion 22 and the plate portion 32 are heated.

Furthermore, in the present embodiment, as shown in FIG. 2, the thermistor 73 is attached to the plate portion 22 and the back surfaces 22 e and 32 e of the plate portion 32, and changes with the temperature change of the

heaters

23 and 33. The temperatures of the heater 23 and the heater 33 are controlled using the resistance value. Reference numeral 74 denotes a fuse. By providing the fuse 74, when the temperature of the upper hair pinching surface 22a or the lower hair pinching surface 32a exceeds a predetermined temperature due to breakage of the control circuit 6a or the like, The energization to the heater 23 and the heater 33 is cut off.

Further, a temperature control switch 7a is provided on the lower grip portion 3a side of the case 30, and by operating the temperature control switch 7a, the set temperature of the upper hair pinching surface 22a and the lower hair pinching surface 32a Can be switched. In the present embodiment, an example in which the set temperature can be switched in five steps is illustrated. The case 30 is provided with five lighting units 71 that are lighted by an LED lamp (not shown). For example, the current setting temperature can be recognized by lighting the lighting units 71 corresponding to each step. I have to.

Moreover, in this embodiment, the hair iron 1 is provided with the control member which controls the relative movement to the lower side holding part 3b side of the upper side holding part 2b.

Specifically, a stopper projection 40 projecting upward is provided at the lower portion of the lower grip 3a of the case 30, and a stopper groove 41 is provided in the lower case 20b of the case 20, and the tip of the stopper projection 40 is a stopper It is made to abut on the bottom of the groove 41. Thus, by bringing the end of the stopper projection 40 into contact with the bottom surface of the stopper groove 41, the rotation of the upper arm 2 and the lower arm 3 in the closing direction is restricted.

In addition, at least one of the

hair gripping members

21 and 31 is supported so as to be relatively reciprocally movable in the vertical direction (the normal direction of the hair gripping surface) with respect to the case (clipping portion main body) 20 and 30. preferable.

For example, by supporting four corners of at least one of the

hair gripping members

21 and 31 with the case 20 or four float springs disposed in the case 30, the

hair gripping members

21 and 31 can be

case

20 , 30 can be moved up and down.

In this way, excessive load is applied to the hair sandwiched between the upper hair sandwiching surface (first hair sandwiching surface) 22a and the lower hair sandwiching surface (second hair sandwiching surface) 32a. It is suppressed, and it becomes possible to suppress the damage to the hair.

Here, in the present embodiment, the blower unit 50 is provided above the upper hair pinching surface 22a of the upper pinching portion (first pinching portion) 2b (the back side of the first hair pinching surface).

Specifically, the upper pinching portion (first pinching portion) 2 b includes a hair pinching unit 25 having an upper hair pinching surface (first hair pinching surface) 22 a. And the ventilation unit 51 which has the ventilation part 50 is provided in the upper part (The opposite side to the 1st hair clamping surface in a hair clamping unit) of the hair clamping unit 25. As shown in FIG.

Furthermore, in the present embodiment, a heat insulating portion is interposed between the upper hair holding surface (first hair holding surface) 22 a and the blower 50.

Specifically, the ceiling wall 25a of the hair nipping unit 25, that is, the upper nipping portion (first nipping portion) 2b side of the upper case 20a is heat resistant such as polybutylene terephthalate (PBT) or polyphenylene sulfide (PPS) It is made of a plastic resin. The heat insulating portion may be formed by interposing a heat insulating material such as felt between the upper hair holding surface (first hair holding surface) 22 a and the blower unit 50.

In the upper case 20a, as shown in FIG. 2, a substantially horizontal flat portion 20e is formed at the rear of the upper grip portion 2a, and an inclined portion 20f is formed at the front end of the flat portion 20e. There is. The top wall 25a of the hair gripping unit 25 is formed at the front end of the upper case 20a by bending the crank 20 downward from the front end of the inclined portion 20f.

At this time, the top wall portion of the hair gripping unit 25 is formed to be located below the flat portion 20e. That is, the hair gripping unit 25 is formed so as to be thinner in the vertical direction. Thus, by forming the hair gripping unit 25 so as to be thinner, the air blowing space can be reduced while suppressing an increase in the overall thickness of the upper gripping portion (first gripping portion) 2b. I try to secure as much as possible.

The air blowing unit 51 includes an air blowing unit 50, and an outer shell 52 covering the upper side of the air blowing unit 50 and forming an outer shell of the upper holding unit (first holding unit) 2b.

The blower unit 50 includes a blower mechanism (a blower mechanism that performs blower blowing by rotation) 53 and a partition 54 that covers the outer periphery of the blower mechanism 53. In the present embodiment, the blower mechanism 53 is formed by connecting the fan 55 to a motor shaft of a motor (not shown), and the blower mechanism 53 is attached to the partition wall 54. Further, the fan 55 is composed of a shaft 55a connected to the motor shaft and a plurality of blades 55b formed on the side of the shaft 55a.

As the blower mechanism 53, an axial fan, a sirocco fan, a turbo fan, a cross flow fan or the like can be used.

Further, in the present embodiment, two air blowing mechanisms 53 are juxtaposed in the longitudinal direction of the upper sandwiching portion (first sandwiching portion) 2b, and the outer periphery of each fan 55 is a partition 54 having a substantially rectangular shape in plan view. Is covered. The air blowing mechanism 53 is supported by the hair gripping unit 25 by attaching the partition 54 to the rib 26 provided on the top wall 25 a of the hair gripping unit 25.

The outer shell 52 has side walls 52a extending downward and outward at both ends in the widthwise direction in a front view, and a curled portion (hair winding portion) 52b around which hair is wound is formed at the center in the widthwise direction. It has a shape having a convex curved surface upward. That is, in the present embodiment, the curled portion 52b is formed on the back side (upper side in FIG. 3) of the upper hair pinching surface (first hair pinching surface) 22a in the upper pinching portion (first pinching portion) 2b. The curled portion 52b corresponds to the curled portion 2d of the upper holding portion 2b.

Then, the outer housing 52 is supported by the columns 28 provided at the four corners of the top wall 25a of the hair gripping unit 25 so that the upper gripping portion (first gripping portion) having the hair gripping unit 25 and the blower unit 51 ) 2b is formed.

Further, in the present embodiment, the outer shell 52 is formed slightly wider than the hair gripping unit 25. Specifically, both widthwise ends 52 c of the outer shell 52 protrude downward and outward from the top wall 25 a of the hair gripping unit 25.

Thus, a gap is formed between the outer housing 52 and the hair holding unit 25 by projecting both widthwise ends 52c of the outer housing 52 downward and outward relative to the top wall 25a of the hair holding unit 25. The gap is a blower 60. The air sent from the air blowing mechanism 53 to the air blowing port is discharged from the air blowing port 60 to the outside. At this time, the wind sent from the blowing mechanism 53 is discharged downward and outward, and the wind is more efficiently applied to the hair sandwiched between the upper hair holding surface 22 a and the lower hair holding surface 32 a ( Cooling air can be supplied. Of course, when the outer shell 52 has a predetermined shape, both widthwise ends 52c of the outer shell 52 are better than the top wall 25a of the hair pinching unit 25 so as to maintain the outer surface of the outer shell 52. There is also a case where it is extended downward and the hair clipper unit 25 is equipped.

Further, in the present embodiment, as shown in FIG. 7, the air blowing port 60 is formed to extend in the longitudinal direction on both ends in the width direction of the hair gripping unit 25.

Furthermore, in the present embodiment, outside air on the outer surface of the upper pinching portion (first pinching portion) 2b other than the upper hair pinching surface (first hair pinching surface) 22a of the outer surface of the upper pinching portion 2b. The inlet 52d is formed to introduce the The air inlet 52 d is for improving the air blowing efficiency of the air blowing unit 51.

In the present embodiment, an air inlet 52 d for introducing outside air into the air blowing unit 51 is formed in the curled portion (hair wound portion) 52 b formed at the center in the width direction of the outer shell 52. As described above, by forming the intake port 52d in the curled portion 52b formed at the center in the width direction of the outer shell 52, the intake port 52d, the blower mechanism 53 and the blower port 60 In the vertical direction, they are arranged in this order. Then, when the air blowing mechanism 53 is driven (including aging to be described later), the outside air in the vicinity of the air inlet 52d is introduced into the upper sandwiching portion 2b from the air inlet 52d and sent to the air blowing port 60 by the air blowing mechanism 53 for blowing air. A series of wind flows are generated that are emitted from the outside 60.

Further, in the present embodiment, the intake port 52d is formed of a plurality of long holes (long hole-like intake ports) extending in the longitudinal direction of the upper sandwiching portion (first sandwiching portion) 2b. Each air inlet (long-hole-like air inlet) 52 d is formed such that both ends thereof exist on the boundary line of the region R1 where the air flow toward the rotation center of the blower mechanism 53 is formed or outside the region R1. There is.

Specifically, a cone formed when the straight line L connecting the root side center (axial center of the air blowing mechanism) of the shaft 55a of the fan 55 and the tip of the blade 55b of the fan 55 is rotated with respect to the rotation axis A A region surrounded by a line of intersection C1 between the surface D and the outer surface of the upper holding portion 2b is a region R1.

A central portion (at least a part) of each intake port (long-hole shaped intake port) 52d is formed in the region R1, and both ends are present on the intersection C1 or outside the region R1. It is formed.

In this way, there is no site that inhibits the introduction of the outside air in each air inlet (the long hole-like air inlet) 52d, and the outside air can be introduced more efficiently.

In the present embodiment, the inner side surfaces at both ends of each intake port (long-hole shaped intake port) 52d are illustrated as extending in the vertical direction, but in each intake port (long-hole shaped intake port) 52d Each intake port (long hole intake port) 52 d may be formed such that the inner side surfaces at both ends extend substantially in parallel with the straight line L. In this way, it can be suppressed that the inner side surface of each intake port (long-hole shaped intake port) 52d becomes a draft resistance at the time of the introduction of the outside air, and the outside air can be introduced more efficiently. .

Further, in the present embodiment, the curvature of the curled portion 52b is made relatively small so as to be a gentle curved surface, so the line of intersection C1 between the conical surface D and the outer surface of the upper holding portion 2b is approximately circular. Become. Accordingly, the line of intersection C1 between the conical surface D and the outer surface of the upper holding portion 2b is substantially concentric with the locus (circumference C2) described by the tip 55c of the blade 55b when the fan 55 is rotated See Figure 5).

Further, in the present embodiment, the straightening vanes 27 are provided on the side opposite to the upper hair holding surface (first hair holding surface) 22 a in the hair holding unit 25.

The shape of the straightening vanes 27 is preferably set so as not to disturb the flow of the delivery wind formed by an arbitrarily selected fan.

For example, as in the case of an axial fan, when the delivery air flows in the rotational axis direction, the straightening vanes 27 are arranged on the top surface of the top wall 25a of the hair gripping unit 25 as shown in FIG. Preferably, they are integrally formed so as to extend radially. The straightening vanes 27 may be provided separately from the top wall 25 a of the hair gripping unit 25. Further, the height of the straightening vanes 27 is preferably as high as possible. The straightening vanes 27 are preferably grounded to the lower surface of the blower mechanism 53.

Furthermore, in the present embodiment, a control circuit 6 b for controlling the rotation of the fan (the air blowing mechanism 53) and the like is accommodated in the case 20, and the air blowing mechanism 53 is accommodated in the control circuit 6 b via the lead wire 8. It is connected.

The cooling button 75 is provided on the hair iron 1 (specifically, the inclined portion 20f of the case 20), and the number of rotations of the fan (the air blowing mechanism 53) 55 is switched by operating the cooling button 75. It can be done. That is, by operating the cooling button 75, the blower mechanism 53 can be switched between the normal operation state and the other state (the blower mechanism 53 is in a stopped state or an aging state described later). ing.

By the way, when the upper sandwiching portion 2b and the lower sandwiching portion 3b are heated, heat is generated, and convective heat transfer, radiation heat transfer, conduction in the

cases

20 and 30 of the upper sandwiching portion 2b and the lower sandwiching portion 3b and inside thereof. The temperature rises due to heat transfer and the like.

Thus, when the temperature around and inside the upper holding portion 2b and the lower holding portion 3b rises, the user may be burned by skin contact or the user may feel the heat during use. It occurs. Moreover, since the temperature of the wind sent from the air blower 60 rises, the temperature difference can not be given to the hair, and there is a problem that the cooling effect of the hair itself and hence the hair setting efficiency are lowered.

Therefore, in the present embodiment, when the thermistor 73 described above is used as a detector, and the thermistor 73 detects that the temperatures of the heater 23 and the heater 33 (heat generating portion) have become equal to or higher than a predetermined temperature, the control circuit 6b Aging is performed by rotating the fan 55.

That is, the hair iron 1 is a thermistor (detector) 73 that detects the temperature of the heater 23 and the heater 33 (heat generating portion), and a control circuit that performs aging of the blower 50 based on the detected temperature of the heater 23 and the heater 33 And (control unit) 6b.

The detection of the predetermined temperature may not be a thermistor type that detects the temperature itself. For example, a predetermined temperature is detected by detecting load current values of the heater 23 and the heater 33 installed as heat sources, determining a correlation between a predetermined temperature and time, and detecting a time obtained from the correlation. You may do it.

Further, in the present embodiment, when the temperatures of the heater 23 and the heater 33 exceed 100 ° C., the blower unit 50 is aged. In the hair iron 1 according to the present embodiment, when the temperature of the heater 23 and the heater 33 exceeds 100 ° C. when the air blowing portion 50 is not aged, the temperature in the air blowing portion 50 exceeds 40 ° C. Therefore, when the temperature of the heater 23 and the heater 33 exceeds 100 ° C., the air blowing unit 50 is aged to secure a predetermined air flow rate, and the temperature in the air blowing unit 50 is 40 ° C. or less It is made to keep close temperature condition).

Here, an example of an operation at the time of using hair iron 1 of the above-mentioned composition is explained.

First, by operating the operation switch 7, the heater 23 and the heater 33 are energized, and the upper hair holding surface 22a and the lower hair holding surface 32a are heated to a predetermined temperature (for example, 170 ° C.) .

The control circuit 6b rotates the fan 55 when the temperature of the heater 23 and the heater 33 detected by the thermistor 73 exceeds 100 ° C. as the temperature of the upper hair sandwiching surface 22a and the lower hair sandwiching surface 32a increases. Aging will be done.

Then, when the upper hair pinching surface 22a and the lower hair pinching surface 32a reach a predetermined temperature (for example, 170 ° C.), the cooling button 75 is operated to increase the number of rotations of the fan 55, and the blower mechanism 53 is brought into the normal operation state. Do. At this time, since the temperature rise in the blower unit 50 is suppressed by rotating the fan 55 to perform aging, the temperature rise of the cooling air blown to the outside from the air blowing port 60 is suppressed, and the temperature of the cooling air is determined. It can be brought closer to the outside temperature.

And, in a state where the hair is arranged to extend in the width direction of the upper sandwiching part 2b and the lower sandwiching part 3b between the heated upper sandwiching part 2b and the lower sandwiching part 3b, the upper hair sandwiching surface 22a and the lower hair holding surface 32a sandwich the hair. Thus, by sandwiching the hair between the heated upper hair holding surface 22a and the lower hair holding surface 32a, hydrogen bonds between the hair fibers are cut.

Then, the hair iron 1 is rotated by half while holding the hair, and the hair on the root side not held by the upper hair holding surface 22a and the lower hair holding surface 32a is wound around the curled portion (hair winding portion) 52b. .

Then, in a state where the hair is pressed against the curled portion (hair wound portion) 52b, curling is applied to the hair by sliding the hair iron 1 along the hair and pulling it toward the end of the hair. Be done.

When performing the above-described series of operations, hair in a state in which hydrogen bonds between hair fibers are broken by heat is wound around the curled portion (hair wound portion) 52b. Therefore, the hair can be easily curled. Furthermore, since the hair that has been trimmed to a desired shape in a state in which hydrogen bonds between hair fibers are cut by heat is cooled by the cooling air blown from the vicinity of the heating unit, the hair is trimmed in a desired shape. The fibers can be more rapidly hydrogen bonded. Therefore, the curl retention of hair can be further enhanced.

As described above, in the present embodiment, when the thermistor 73 is used as a detector and the thermistor 73 detects that the temperature of the heater 23 and the heater 33 has become equal to or higher than the predetermined temperature, the control circuit 6b uses the fan 55. Is rotating to perform aging.

That is, the hair iron 1 is a thermistor (detector) 73 that detects the temperature of the heater 23 and the heater 33 (heat generating portion), and a control circuit that performs aging of the blower 50 based on the detected temperature of the heater 23 and the heater 33 (Control unit) 6 b is provided.

Therefore, the temperature in the vicinity of the blower unit 50 can be suppressed from being excessively increased, and the temperature of the cooling air sent from the blower port 60 can also be reduced. As a result, the hair styling efficiency of the hair iron 1 can be suppressed from decreasing.

As mentioned above, although preferred embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible.

For example, in the said embodiment, it is also possible to apply this invention to the hair iron in which ion production | generation parts, such as a mist production | generation part and a metal microparticle production | generation part, are not provided.

Moreover, in the said embodiment, while making a heat insulation part intervene between an upper side hair pinching surface and a ventilation part, the hair iron which provided the straightening vane was illustrated, but the structure of a hair iron is not limited to this .

In addition, the specifications (shape, size, layout, etc.) of the hair holding surface, the grip portion, the air outlet, and other details can be appropriately changed.

According to the present invention, it is possible to obtain a hair iron capable of suppressing the reduction in hair setting efficiency.
