  Although the shape of the infrared heater is various, if it is a rod shape, infrared rays are emitted in all directions intersecting the longitudinal direction, but the infrared rays reflected through the reflector are collected toward the hair However, the infrared radiation emitted without passing through the reflector diffuses toward the hair. As described above, in the conventional backside heater, the infrared rays to be converged and the divergent infrared rays intersect, and thus the energy distribution of the infrared rays may not be in a desired state.

  The present invention has been proposed in view of the above situation. That is, it is an object of the present invention to provide a hair treatment apparatus that can make the energy distribution of infrared rays into a desired state and can irradiate infrared rays to hair effectively.

  A hair treatment device according to the present invention is a treatment main body provided with an infrared radiating unit that radiates infrared rays radiated to the hair of a subject, and a reflection unit that reflects infrared rays toward hair, and the treatment main body. A supporting portion for supporting the portion and disposing it in the vicinity of the head of the subject, wherein the reflecting portion has a shape curved in an arc shape, and the infrared radiation portion is disposed on the concave surface side, and the infrared The radiating section is flat, and both radiating surfaces of the infrared radiating section face the reflecting section.

Therefore, the energy distribution of the infrared rays can be set to a desired state, and the hairs can be effectively irradiated with the infrared rays. In addition, since most of the infrared rays are reflected by the reflection part, in other words, the amount of the infrared light radiated without passing through the reflection part is small. That is, in the vicinity of the edge of the reflection portion, if the infrared light radiated without passing through the reflection portion is small, the infrared light directly radiated to members such as the cover disposed near the edge of the reflection portion is also small, The influence of heat on the cover and the like can be suppressed.

  The following is a detailed description of the reflection unit 22 and the infrared radiation unit 21. FIG. 4 is a cross-sectional view of the reflecting section 22, and shows an arrangement of the infrared radiation section 21 in the reflecting section 22.

  As shown in FIG. 4, the cross-sectional shape of the reflection unit 22 is represented by [Equation 1] in a two-dimensional coordinate system represented by orthogonal Y-axis and Z-axis. In addition, as shown in FIG. 4, when viewed from above, the location where the degree of curvature is the largest is defined as the origin, the width direction of the reflection unit 22 is the Y axis, and the Y direction is the thickness direction of the reflection unit 22. Is a Z axis.

[Equation 1]

r ₁ : radius of curvature k: conic coefficient C: 1 / r ₁
The radius of curvature is r ₁ = 14 to 19
The conic coefficient is k = −0.4 to −0.9.

  The infrared radiating section 21 is, for example, a flat sheet-shaped surface source section 31 in which filament carbon is woven and sealed in a container 30 formed in a rod shape with quartz glass or the like. The infrared radiation temperature is preferably, for example, 1100 to 1400K.

  The distance between the infrared irradiation unit 21 and the concave surface 23 is such that the reflection unit 23 is not excessively heated. Both radiation surfaces 32 a and b of the infrared irradiator 21 face the concave surface 23 of the reflector 22. That is, the surface source unit 31 is disposed in parallel with the Z axis and orthogonal to the Y axis, one radiation surface 32a faces one concave inner surface 33a of the concave surface 23, and the other radiation surface 32b , And the other concave inner surface 33b of the concave surface 23.

  As described above, the hair processing device 1 is configured. The following is a description of the operation of the hair processing device 1. FIG. 5 schematically shows the state of irradiation of infrared rays viewed from above.

For example, in FIG. 1, the hair treatment device 1 is installed on the back surface of the subject, and the connecting arm 16 is arranged near the head of the subject. The head is disposed on the rotation axis P, and the treatment main body 15 is disposed near the occiput of the subject. At this time, when the pedal 7 of the support leg 4 is operated, the piston cylinder of the support main body 8 is operated, and the treatment main body 15 moves up and down together with the support connecting portion 11 with respect to the support main body 8. When the power switch 9 is turned on, infrared rays are radiated from the infrared radiating section 21 in FIG. At the same time, when the blower 20 operates, the air is sucked from the intake hole 19 (flow path 29a), and the wind is sent to the convex surface 24 of the reflector 22 (flow path 29b). The wind that has hit the convex surface 24 is heated very slightly by the heat of the reflection unit 22 and hits the wind direction plate 27 and is discharged from the outlet 26 in a state of not being hot air (flow paths 29c and 29d). The air volume is, for example, 1 m ³ / min.

  As shown in FIG. 5, the distance between the virtual line S in the reflection unit 22 and the head H of the subject is about 50 to 300 mm. Here, the virtual line S is a line that passes through the end on the side of the subject and is parallel to the Y axis in the reflection unit 22. Since both radiation surfaces 32a and 32b of the infrared irradiation unit 21 face the concave surface 23 of the reflection unit 22, the infrared light is reflected by one of the radiation surfaces 32a on one concave inner surface 33a of the concave surface 23, The other radiation surface 32b reflects on the other concave inner surface 33b of the concave surface 23. The reflected infrared rays intersect before the occipital region and diffuse from the intersection C toward the occipital region. The infrared rays are radiated to the hair in the range of the irradiation width W. The irradiation width W is determined based on the distance from the virtual line S to the head H of the subject, the radius of curvature, and the conic coefficient.

  The infrared rays reflected by the reflection part 22 are absorbed by the moisture on the surface of the hair, and only the moisture on the surface of the hair evaporates while the moisture remains inside the hair. At the same time, the cuticle on the surface of the hair is tightened by the wind from the blower unit 20 while the moisture inside remains. The wind separates not only the surface of the hair but also the dense hair and reaches the hair inside, so that each hair is treated similarly throughout the hair. That is, the hair is in an appropriate state for performing various treatments by drying the surface while leaving moisture inside.

  The treatment main body 15 rotates around the head of the subject with respect to the support 2 in accordance with the operation mode selected by the operation unit 10 of the support main body 8. For example, when the rotation angle of the lower end of the treatment main body 15 farthest from the rotation center is located at the lower end in the vertical direction (see FIG. 1), the rotation angle of the treatment main body 15 is 360 degrees. Can be rotated degrees. Since the program for determining the operation mode is arbitrary, the treatment main body 15 can reciprocate at an arbitrary rotation angle. You can also stop with.

  As described above, the hair processing device 1 is configured. The following is a description of the effects of the hair treatment device 1.

  In the hair treatment apparatus 1, an infrared radiation section 21 having a flat thin plate-shaped surface source section 31 in which filamentary carbon is woven is arranged in parallel with the Z axis and perpendicular to the Y axis. One radiating surface 32a faces one concave inner surface 33a of the concave surface 23, and the other radiating surface 32b faces another concave inner surface 33b of the concave surface 23 (see FIG. 4). That is, in the flat infrared irradiating unit, since both of the radiation surfaces 32a and b face the concave surface 23, most of the infrared radiation radiated from the both radiation surfaces 32a and b is reflected by the concave surface 23. In particular, by calculating the reflection angle of the infrared ray in advance and designing the curved surface of the reflecting portion according to the above [Equation 1], it is possible to condense the infrared ray in a desired direction and control the energy distribution. Therefore, the energy distribution of the infrared rays can be set to a desired state, and the hairs can be effectively irradiated with the infrared rays.

  In addition, since most of the infrared rays are reflected by the concave surface 23, in other words, the amount of the infrared light radiated without passing through the concave surface 23 is small. That is, if the amount of infrared light radiated without passing through the concave surface 23 near the edge of the reflecting portion 22 is small, the amount of infrared light directly radiated to members such as the guard cover 28 arranged near the edge of the reflecting portion 22 is also small. Therefore, the influence of heat on the guard cover 28 and the like can be suppressed.

  In the hair treatment device 1, the infrared light reflected by the concave surface 23 intersects before the head H, and diffuses from the intersection C toward the head H (see FIG. 5). With this configuration, the reflection range of the infrared rays toward the head H side from the intersection C can be made wider than the width of the reflection part 22. Therefore, the size of the reflection unit 22 can be reduced regardless of the irradiation range.

In particular, the distance between the imaginary line S and the head H of the subject in the reflection section 22 is about 50 to 300 mm, the radius of curvature is r ₁ = 14 to 19, and the conic coefficient is k = −0.4 to −−. By adjusting each of the values between 0.9 and 0.9, the irradiation width W of the infrared light applied to the hair can be arbitrarily set. Specifically, the irradiation width W can be adjusted up to 65 mm (irradiation width W = 130 mm) in both width directions from the center of the head H, and in this range, the energy distribution of the infrared rays can be adjusted to a desired state. And effectively irradiate the hair with infrared light. As described above, since the energy distribution and the irradiation range of the infrared ray can be selected, it is possible to realize appropriate heating and a dry state of the hair according to the treatment.

  The treatment main body 15 rotates around the head of the subject with respect to the connection main body 14 via the gear motor of the support connection part 11. Therefore, the hair treatment device 1 can irradiate the entire hair with infrared rays without unevenness.

  The treatment main body 15 is vertically long in the vertical direction, and a connecting arm 16 at the upper end of the treatment main body 15 is connected to the connection main body 14 of the support 2. Therefore, the hair processing apparatus 1 can irradiate long hair with infrared rays without unevenness.

  The treatment main body 15 includes, in the opening 18, a reflecting portion 22 with the concave surface 23 facing outward, and an outlet 26 through which the wind blown from the blower 20 toward the hair passes. With this configuration, the infrared rays reflected by the reflection unit 22 and the wind from the blower unit 20 are emitted through the opening 18 which is a common outlet. Therefore, the hair processing apparatus 1 can separately emit infrared light and wind from one place toward the hair.

  The following is a description of embodiments of the present invention. FIG. 6 shows the distribution of infrared rays in the hair treatment device 1. Note that the Y axis in FIG. 6 is the same as that in FIG. 4, and the X axis is the longitudinal direction of the infrared radiation section 21. The origin is the center of the infrared radiation section 21 and the center of the infrared radiation section 21 in the longitudinal direction.

  The distance between the virtual line S and the head H was set to about 150 mm, and the irradiance of infrared rays was calculated on a virtual plane in contact with the back of the head. As shown in FIG. 6, the distribution of the infrared irradiance on the Y-axis and the X-axis shows that the irradiation is efficiently performed in the virtual plane when the irradiation width W is in the range of 130 mm.

  As described above, the embodiments of the present invention have been described in detail, but the present invention is not limited to the above embodiments. The present invention is capable of various design changes without departing from the scope of the claims.
