It is connected to the tip of the road 11. A connection port 12 is provided at the base end of the relay channel 11, and a pipe 51 of the suction device 50 is connected to the connection port 12. The suction device 50 can suction the vapor or the like from the opening 32 of the suction flow channel 31 by the operation of the fan 52, and discharge the vapor or the like from the discharge port 53 to the outside.

  FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a view of one of the holding portions 30 shown in FIG. As shown in FIGS. 2 and 3, one of the holding portions 30 is a block-shaped member formed in a rectangular shape in a plan view, and the back side is fitted and supported by the support member 10. A heating section 60 made of a plate-shaped ceramic heater is closely fixed to the back surface of the one holding section 30. The heating unit 60 may be any unit that can generate heat when energized, and another electric heater may be used. The holding portion 30 is preferably formed of a metal material having excellent thermal conductivity and corrosion resistance, such as an aluminum alloy.

  A first contact portion 35 and a second contact portion 36 are provided on the front side of one of the holding portions 30 with a space therebetween. The first contact portion 35 and the second contact portion 36 have a constant cross-sectional shape shown in FIG. 2 and are formed in a band shape in plan view so as to extend in parallel with each other. The first contact portion 35 has a flat surface, while the second contact portion 36 has a curved surface whose surface bulges in a circular arc shape. Both ends in the longitudinal direction of the first contact portion 35 and the second contact portion 36 are connected by connecting portions 38 and 39, respectively, and the first contact portion 35, the second contact portion 36 and the connecting portion 38, A concave portion 37 that is surrounded by 39 and extends in the longitudinal direction of the holding portion 30 is formed. The first contact portion 35, the second contact portion 36, and the connecting portions 38 and 39 can be integrally formed by, for example, cutting.

  The suction channel 31 is formed so as to extend in the longitudinal direction of the concave portion 37 inside the one holding portion 30, and communicates with a plurality of openings 32 formed at equal intervals on the bottom surface of the concave portion 37. Insertion passages 33 and 34 are formed on both sides of the suction passage 31. Electric wires (not shown) for supplying electricity to the heating unit 60 are inserted into the insertion passages 33 and 34, and electric power can be supplied to the heating unit 60 from an external power supply (not shown).

  FIG. 4 is a cross-sectional view taken along line CC of FIG. 1, and FIG. 5 is a view of the other holding portion 40 shown in FIG. As shown in FIGS. 4 and 5, the other holding unit 40 has the same configuration as the one holding unit 30 except that the other holding unit 40 does not include the suction path 31 and the opening 32 formed in the one holding unit 30. The insertion passages 43 and 44 are formed inside. A first contact portion 45 and a second contact portion 46 are provided on the surface side of the other holding portion 40 with an interval therebetween. Both ends in the longitudinal direction of the first contact portion 45 and the second contact portion 46 are connected by connecting portions 48 and 49, respectively, and the first contact portion 45, the second contact portion 46 and the connecting portion 48, A concave portion 47 is formed which is surrounded by 49 and extends in the longitudinal direction of the other holding portion 40. The height of the connecting portions 38, 39, 48, 49 of the pair of holding portions 30, 40 is such that the first contact portions 35, 45 and the second contact portions 36, 46 reliably contact each other. It is preferable that these heights are approximately the same or slightly lower.

  A heating unit 70 is closely fixed to the back surface of the other holding unit 40. Although the electric heating type hair iron 1 of the present embodiment is provided with the heating units 60 and 70 corresponding to both of the pair of holding units 30 and 40, the heating unit may be a single unit. The heating section may be arranged so that heat is transferred to one of the forgings 40 through the other.

  As shown in FIG. 6, the electric hair curler 1 having the above configuration closes the pair of support members 10 and 20, which are openably and closably connected, so as to pinch the wet hair H after towel drying or the like. After being sandwiched between the sections 30 and 40, the switch 13 provided on one of the support members 10 is operated to heat the pair of sandwiching sections 30 and 40 by energizing the heating sections 60 and 70, and the suction device. Activate 50.

  When the pair of support members 10 and 20 are closed, the first contact portions 35 and 45 and the second contact portions 36 and 37 contact each other, and a space of the concave portions 37 and 47 is formed therebetween. You. The steam generated by heating the hair H is drawn into the suction channel 31 through the concave portions 37 and 47 by the operation of the suction device 50.

  In the configuration in which the electrothermal hair iron 1 of the present embodiment does not include a mechanism for supplying steam to the hair H, the suction device 50 connected via the suction flow path 31 operates the pair of holding portions 30 and 40. It is configured to be able to be sucked, and has been developed based on a new idea of sucking steam generated from the hair H instead of steam supplied from the outside. According to the electric hair iron 1, the steam generated from the hair H can be reliably prevented from spouting around the pair of holding portions 30 and 40, so that it is used near the scalp such as at the base of the hair. Even in such a case, there is no possibility that high-temperature steam will blow out to the scalp, and the treatment can be performed comfortably.

  Also, the electrothermal hair iron 1 has the first contact portions 35, 45 having a flat surface, while the second contact portions 36, 46 have a curved surface, so that the first contact portion 35, 45 has a curved surface. Since the second contact portions 36 and 46 contact each other with an area smaller than the area of the contact portions between the first and second contact portions 36 and 46, the hair H is brought into contact with the first contact portions 35 and 45 at the second contact portions 36 and 46. Pressed at a higher pressure. Therefore, by sliding the pair of holding portions 30 and 40 holding the hair H in the direction indicated by the arrow E in FIG. 6, the hair root side of the hair H is held by the first contact portions 35 and 45 while the tip side is held. Can be strongly squeezed by the second contact portions 36 and 46, so that the torsion of the hair H can be removed. The width W2 of the portion where the surfaces of the second contact portions 36 and 46 are curved is made smaller than the width W1 of the portion where the surfaces of the first contact portions 35 and 45 are planar. Is preferred, whereby the above-described effects can be more reliably achieved. Although the second contact portions 36 and 46 of the present embodiment have curved surfaces having a circular arc cross section, other curved surfaces having a cross section such as an elliptical arc or a wavy shape may be used.

  As mentioned above, although one Embodiment of this invention was described in full detail, the specific aspect of this invention is not limited to the said Embodiment. For example, in the present embodiment, the suction flow path 31 that suctions between the pair of holding sections 30 and 40 is provided only in one of the holding sections 30, but the suction flow path is provided in both of the pair of holding sections 30 and 40. May be provided and connected to the branched pipes 51 so that both of the pair of holding portions 30 and 40 can suck the steam.
