A heating portion 70 is tightly fixed to the back surface of the other holding portion 40 . The electric heating hair iron 1 of this embodiment is provided with the heating portions 60 and 70 corresponding to both of the pair of holding portions 30 and 40, but the heating portion may be a single heating portion. The heating portions may be arranged such that heat is transferred through one of 40 to the other.

As shown in FIG. 6, the electric heating type hair iron 1 having the above-described configuration holds wet hair H after drying with a towel or the like by closing a pair of support members 10 and 20 which are connected so as to be openable and closable. After sandwiching between the portions 30 and 40, the switch 13 provided on one of the supporting members 10 is operated to energize the heating portions 60 and 70 to heat the pair of sandwiching portions 30 and 40 and the suction device. 50 is activated.

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 are brought into contact with each other, and spaces of the concave portions 37 and 47 are formed therebetween. be. 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 .

The electric heating hair iron 1 of this embodiment has a configuration that does not include a mechanism for supplying steam to the hair H, and the suction device 50 connected via the suction flow path 31 operates to separate the pair of holding portions 30 and 40. It is configured to be able to be sucked, and was developed based on a novel idea of sucking steam generated from the hair H instead of steam supplied from the outside. According to this electric heating type hair iron 1, it is possible to reliably prevent the steam generated from the hair H from blowing out around the pair of clamping parts 30, 40, so that it can be used near the scalp such as the root of the hair. Even in such a case, the treatment can be performed comfortably without the risk of hot steam blowing out to the scalp.

In the electric heating hair iron 1, the surfaces of the first contact portions 35 and 45 are planar, while the surfaces of the second contact portions 36 and 46 are curved. , 45, the second contact portions 36, 46 contact with each other over an area smaller than that of the contact portions between the hair H and the first contact portions 35, 45. pressed with a higher pressure than Therefore, by sliding the pair of holding portions 30 and 40 holding the hair H in the direction of arrow E in FIG. can be strongly squeezed by the second contact portions 36, 46, the twisting of the hair H can be removed. The width W2 of the portions where the surfaces of the second contact portions 36 and 46 are curved is smaller than the width W1 of the portions where the surfaces of the first contact portions 35 and 45 are formed flat. is preferable, whereby the above effects can be more reliably achieved. Although the surfaces of the second contact portions 36 and 46 of the present embodiment are curved with an arcuate cross-section, they may be curved with other cross-sectional shapes such as elliptical arcs and waves.
