Description

  The present invention relates to a hair heating device and a hair heating method. More specifically, the present invention relates to a hair heating apparatus and a hair heating method for heating hair by swinging a heater unit that is curved around a rotation center axis when permanent is applied to hair at a beauty salon or the like.

As a prior art regarding a hair heating apparatus and a hair heating method, the thing of the following patent documents 1 and 2 is known, for example.
JP 10-113218 A JP 2002-125745 A

  According to the invention shown in FIG. 3 described in the above-mentioned document 1, the hair is heated by oscillating one heater unit having the rotation center axis oriented obliquely in the front-rear direction. Further, in the invention described in Document 2, one heating of the hair is performed by oscillating two heater units with the rotation center axis oriented obliquely in the front-rear direction with respect to the fixed heater unit.

  However, according to the prior art, since the heater unit is rotated at a position passing through the rotation center axis, the field of view tends to be blocked by the tip of the heater unit. In addition, it is desirable that the frontal head is uniformly heated by a heater, but according to the above configuration, the heating is concentrated on a part or the view is blocked.

  In view of such a conventional situation, an object of the present invention is to provide a hair heating apparatus and a hair heating method that can sufficiently heat the frontal region without obstructing the field of view.

In order to achieve the above object, the hair heating device and the hair heating method according to the present invention are characterized in that the rotation center axis is set in a configuration for heating the hair by swinging a heater unit curved around the rotation center axis. Oriented in the front-rear direction of the head,
One end of the heater unit is supported around the rotation center axis on the back of the head,
The other end of the heater unit is separated from the rotation center axis.

According to the same feature, since the other end of the heater unit is separated from the rotation center axis, the heater unit can be swung while avoiding the face portion.
Moreover, it is preferable that the string of the curved portion of the heater unit is inclined upward with respect to the rotation center axis. This is because the trajectory of the forehead draws a circular arc trajectory and can sufficiently heat the back of the head without obstructing the view.

  The heater of the heater unit is a linear heater, and the folded portion of the heater may be positioned on the other end side of the heater unit. This is because the forehead, particularly the bangs, can be heated sufficiently.

  Further, the heater of the heater unit may be a linear heater, and the one end side of the heater may protrude below the rotation center axis. This is because the irradiation range of the back of the head, particularly the neck portion, can be expanded and the thermal radiation density can be improved. Also for the “neckline portion” in the vicinity of the rotation axis, the heating characteristics are improved because the infrared irradiation density is improved. In this case, the one end side portion of the heater may be linear.

  Further, the swing drive device of the heater unit may include a worm gear and a worm wheel between the power source and the rotation center shaft. Even when the heater unit exceeds the maximum swing point, it is possible to suppress the shake of the heater unit due to gear backlash or the like.

  Moreover, you may use a ceramic material for the reflector of the heater in a heater unit. According to the characteristics, the heat radiation efficiency of the heater can be improved by the far infrared radiation effect of the ceramic material.

  On the other hand, the hair heating method using the hair heating apparatus described in the above feature is characterized in that the rotation center axis is oriented in the front-rear direction of the head and the heater unit is swung around the rotation center axis.

According to the characteristics of the hair heating device and the hair heating method according to the present invention, the other end of the heater unit is separated from the rotation center axis, so that the heater unit can be swung while avoiding the face portion. Therefore, it is possible to sufficiently heat the frontal region without obscuring the field of view and by swinging the portion facing the frontal region in an arc shape.
Other objects, configurations, and effects of the present invention will become apparent from the following embodiments of the present invention.

Next, the present invention will be described in more detail with reference to the accompanying drawings as appropriate.
As shown in FIGS. 1 and 2, the hair heating device 1 according to the present invention includes a heater unit 2, a drive unit 3, an upper column 4, a lower column 5, a pedestal 6, and a handle 7. The heater unit 2 is supported by the drive unit 3 so as to be driven to rotate about the rotation center axis L1, and the string L2 in the arc portion of the heater unit 2 is inclined about 30 degrees with respect to the rotation center axis L1. A heater unit 2 is formed. A caster is attached to the base 6 and can be moved by a handle 7, and the space between the upper support 4 and the lower support 5 can be extended.

  The heater unit 2 is curved so as to surround the head H, and along the curve, the heater 10 is provided so as to be parallel at the heater intermediate portion 10b and the heater rear portion 10c, and folded at the heater front portion 10a. It has been. The space between the heater front portion 10a and the rotation center axis L1 is released, and the field of view of the face F is not obstructed even when the heater unit 2 and the heater 10 are driven and rotated around the rotation center axis L1. In addition, since the front part Ha of the frontal head H1 that requires heat is folded at the heater front part 10a, sufficient heating is possible. Further, the heater rear portion 10c is suspended vertically from the arc portion of the heater unit 2, and rotates around the rotation center axis L1 to sufficiently heat the neckline portion H4. The back head H2 and the head top H3 are curved so that they can be heated almost evenly.

  The heater 10 swings as shown in FIG. 2, but the intermediate position 10x hair heating device 1 and the hair heating method position are the highest positions close to the top of the head H3, and the left end position 10y and right end position 10z are left and right. It is the limit position. The power is cut off at the pre-limit positions PA1 and PB1 until the left and right limit positions PA2 and PB2, and the vehicle starts decelerating, stops at the left and right limit positions PA2 and PB2, and swings in the opposite direction again.

  As shown in FIGS. 3 and 4, the heater unit 2 is provided with a pair of reflectors 14 in the outer frame 11 and the inner frame 12, and the heater 10 is appropriately positioned with respect to each reflector 14 by a supporter 15. Support intermittently. The heater 10 can be a far infrared heater or the like. The heater 10 is covered with a cover 13. A ceramic layer is formed on the inner side of the reflection plate 14, and the far-infrared radiation effect can be increased by, for example, 30% or more depending on the ceramic material by reflection.

  As shown in FIGS. 5 to 7, the drive mechanism 30 housed in the drive unit 3 includes a motor 33 that is a drive source and a gear mechanism that rotates a driven shaft 36 that is the rotation center axis L <b> 1. In the gear mechanism, the driven shaft 36 is penetrated and supported by the first frame 31 and the second frame 32, the motor shaft 34 of the motor 33 is orthogonal to the driven shaft 36, and the worm gear 35 fixed to the motor shaft 34 and the driven shaft 36 are connected. A fixed worm wheel 37 is engaged. The driven shaft 36 is regulated in a left-right position by a pair of fixed bearings 36a, 36b provided so as to pass through and sandwich a frame (not shown), and the relative position between the worm wheel 37, the first frame 31 and the motor shaft 34 is set horizontally. It can be adjusted by the adjustment tool 38. Further, by pushing up the motor bearings 34a and 34b disposed above and below the worm gear 35 by the vertical fixture 39, backlash between the worm gear 35 and the worm wheel 37 is reduced, and the play of the gear mechanism is prevented. Thereby, when the heater unit 2 swings beyond the intermediate position 10x, the heater unit 2 is prevented from vibrating.

  As shown in FIG. 8, the drive control device 40 that controls the swing of the heater unit 2 includes a cam 41, an optical sensor 46, and left and right limit switches 48 and 49. The cam 41 is fixed to the driven shaft 36 and includes a drive unit 42, a left limiting unit 43, and a right limiting unit 44 that are in contact with the rollers 48 a and 49 a of the left and right limit switches 48 and 49. The optical sensor 46 detects the center end 45 to determine the intermediate position 10x.

  In a state where both the rollers 48a and 49a are in contact with the drive unit 42, the motor 33 rotates at a normal speed. When the left rotation progresses and the roller 48a starts to contact the left limiter 43, the left limit switch 48 is cut and the power to the motor 33 is controlled to be reduced or cut off, and the heater unit swings. Slows down. Then, a swing driving force in the reverse direction is transmitted after a certain time, and a right swing is performed. The behavior of the right limit switch and the right limiter 44 in the right swing is the same as that in the left swing. In this way, the left and right alternating swinging of the heater unit 2 is decelerated at the left and right ends and smoothly performed without rattling at the center of the highest position, and no unnecessary stress is applied to the gear mechanism.

Finally, another embodiment of the present invention will be described.
In the drive mechanism 30 described above, the motor 33 and the gear mechanism are used. However, a crank mechanism, a piston, or the like may be used. However, the worm gear 35 mechanism is excellent because of the simplicity of the apparatus and the smoothness of movement.
In the above embodiment, a linear heater is used. However, various heater shapes can be used. For example, a planar heater may be used.

  In the said embodiment, the heater unit 2 was comprised by the semicircular arc shaped part shown by the code | symbol 10b, and the linear part shown by the code | symbol 10c. However, as shown in FIG. 9A, it is also possible to suspend the linear portion 10c perpendicularly from the tangential direction of the arc 10b, or to start the arc-shaped portion 10b from the linear portion 10c. However, in FIG. 9A, the heating of the neck portion H4 is insufficient, and in FIG. 9B, the heater 10 may be too close to the occipital region H2, and the aspect of FIG. 1 is excellent.
