In the hair care device provided with the above, the gist is that a high temperature part is formed on the front side in the treatment direction of the hair contact member, and a low temperature part whose temperature is lower than the high temperature part is formed on the rear side.

  The gist of the second feature is that the heating unit is arranged on the back side of the hair contact member on the front side in the treatment direction.

  The third feature is that the hair contact member is formed of a material containing a heat insulating material, and the content of the heat insulating material is varied in the treatment direction.

  The gist of the fourth feature is that cooling means for cooling the hair contact member is arranged on the back side of the hair contact member on the rear side in the treatment direction.

  The fifth feature is summarized in that the cooling means is a Peltier element.

  The gist of the sixth feature is that the hair contact member includes a heat blocking part disposed between the high temperature part and the low temperature part.

  The gist of the seventh feature is that the heat shut-off portion extends along the longitudinal direction of the hair contact member and is a concave groove portion in which the back surface of the hair contact member is recessed.

  The eighth feature is summarized in that a plurality of the hair contact members are provided side by side in the treatment direction, and the surfaces of the plurality of hair contact members are covered with a smooth continuous surface.

  The ninth feature is summarized in that the hair contact member is provided in either of the pair of sandwiching portions.

  According to the hair care device of the present invention, the high temperature part is formed on the front side in the treatment direction of the hair contact member, and the low temperature part whose temperature is lower than the high temperature part is formed on the rear side. After heating and straightening the hair on the side, the hair can be cooled on the posterior side where it has become cold. At this time, since the high temperature part and the low temperature part are provided in one hair contact member itself having a heating part to generate a temperature gradient, the hair contact member is continuous from the high temperature part surface to the low temperature part surface. It becomes a surface. Thereby, since it can prevent that a discontinuous part is formed in the surface between a high temperature part and a low-temperature part, it can suppress that a hair is damaged at the time of a treatment, and can operate by smooth operation | movement.

[First Embodiment]
FIG. 1 and FIG. 2 are diagrams showing a first embodiment of a hair care device according to the present invention. In this embodiment, the present invention is applied to a hair iron 1 as a hair care device.

  As shown in FIG. 1, the hair iron 1 includes a pair of sandwiching portions 2 and 3 for performing treatment while sandwiching hair. These sandwiching portions 2 and 3 are formed of a heat insulating material having an insulating property such as a synthetic resin, and the base end portions 2b and 3b are rotatably connected so that the front end portions 2a and 3a can be opened and closed. Has been.

  At this time, it is preferable that the clamping parts 2 and 3 are urged in the direction in which the distal end parts 2a and 3a side open. Thereby, by pinching the hair between the distal end portions 2a and 3a in an open state and gripping the proximal end portions 2b and 3b, the distal end portions 2a and 3a can be closed and the hair can be easily sandwiched. In addition, the rotation connection position of the clamping parts 2 and 3 is not restricted to the base end parts 2b and 3b, The intermediate part of the clamping parts 2 and 3 may be sufficient.

  Here, the hair treatment means an action of correcting the hair by moving the hair in the extending direction while holding the hair between the holding portions 2 and 3, and the correction of the hair is performed by heating.

  A plate 4 as a hair contact member that directly contacts the hair is provided on the opposing surfaces of the tip portions 2a and 3a of the pair of sandwiching portions 2 and 3, respectively.

  In the present embodiment, each plate 4 is formed in a rectangular shape having a predetermined thickness and extending in the longitudinal direction (left and right direction in FIG. 1) of the sandwiching portions 2 and 3, and the surface 4a of each plate 4 is flat. It is a surface. The shape of the plate 4 is not limited to a rectangular shape, and may be any shape that is effective for treating hair. Further, the surface 4a is not limited to a flat surface, but can have a surface shape along the hairstyle to be corrected.

  As shown in FIG. 2, a recess 2c having a substantially U-shaped cross section is formed at the distal end 2a of the sandwiching portion 2 on which the plate 4 is provided. Inside the open side (upper end in the figure) of the recess 2c The plate 4 is fixed so as to be fitted into the plate. At this time, the surface 4a of the plate 4 protrudes by a predetermined amount from the open end of the recess 2c so that the hair can be held by the surface 4a of the plate 4. A space S is formed between the bottom surface of the recess 2 c and the back surface 4 b of the plate 4.

  Although not shown, the structure of the tip 3a is the same as that of the above-described one clamping part 2 even in the other clamping part 3. FIG. 2 shows the structure of the front end portion of the sandwiching portion 2. In FIG. 2, the reference numerals of the components corresponding to the sandwiching portion 3 are appended with (). The same applies to FIG. 3, FIG. 4, FIG. 5, FIG. 8, FIG.

  That is, a recess 3c having a substantially U-shaped cross section is also formed at the tip 3a of the sandwiching portion 3, and the plate 4 is fixed so as to be fitted into the open side of the recess 3c. Even in this case, a predetermined space S is formed between the bottom surface of the recess 3 c and the back surface 4 b of the plate 4.

  In the plate 4, the treatment direction α by the hair iron 1 is the width direction of the plate 4, and each plate 4 has a high temperature portion TH on the front side of the treatment direction α and a low temperature portion TL on the rear side. Thus, by providing the plate 4 with the high temperature portion TH and the low temperature portion TL, a temperature gradient can be generated in one plate 4 itself.

  That is, the high temperature part TH has a heater (heating part) 6 attached to the back surface 4b side of the plate 4 on the front side in the treatment direction α, and the heater 6 generates heat to constitute the high temperature part TH. At this time, the heater 6 extends along the longitudinal direction of the plate 4, and the high temperature portion TH is provided over substantially the entire length of the plate 4. Of course, the high temperature part TH is formed by the same structure also in the plate 4 of the other clamping part 3.

  The high temperature portion TH and the low temperature portion TL that generate the temperature gradient may be provided on either one of the plates 4 provided in the pair of sandwiching portions 2 and 3, respectively, but in the present embodiment both plates 4 are provided. Provided. Therefore, a temperature gradient is formed on each of the plates 4 of the two sandwiching portions 2 and 3.

  The plate 4 is basically formed of a material having good thermal conductivity. In this embodiment, the plate 4 is formed by including a heat insulating material in the material, and the content rate of the heat insulating material is determined according to the treatment direction. Different by α. That is, in the present embodiment, the content of the heat insulating material is reduced on the high temperature portion TH side, and the content of the heat insulating material is increased on the low temperature portion TL side. The content characteristic k of the heat insulating material at this time is shown in the upper half in FIG.

  The plate 4 is heated to a high temperature part TH by applying current to the heater 6 to generate heat, and this heat is transmitted to the low temperature part TL side through the plate 4. At this time, the content rate of the heat insulating material increases toward the low temperature part TL side, that is, the content of the heat insulating material increases, so that the heat transferred from the high temperature part TH side to the low temperature part TL side decreases. As a result, a noticeable temperature gradient is generated in the plate 4.

  Furthermore, a control unit 7 that controls the value of the current applied to the heater 6 is housed in the space S of one clamping unit 2. Further, a switch 8 for turning on / off the power to the heater 6 is provided on the outer side of the holding unit 2 on the same side as the control unit 7 is provided.

  A power cord 9 to be plugged into an outlet extends from the base end portion 2b side of the sandwiching portion 2. Electric power can be supplied to the heater 6 by inserting the power cord 9 into the outlet and turning on the switch 8.

  Therefore, when setting the hair with the hair iron 1 of the present embodiment, the power cord 9 is inserted into the outlet and the switch 8 is turned on to supply power to the heater 6 via the control unit 7 so that the heater 6 Heated. Then, a temperature gradient is generated between the high temperature portion TH and the low temperature portion TL in the plate 4. In this state, the hair is clamped between the tip portions 2a and 3a of the clamping portions 2 and 3, and the curling iron 1 is slowly moved in the treatment direction α. The treatment direction α at this time is preferably the hair end direction from the head side.

  Then, the hair held between the pair of holding portions 2 and 3 moves relatively from the high temperature portion TH side to the low temperature portion TL side of the plate 4 as the hair iron 1 moves. As a result, the hair is first heated at the high temperature portion TH, and straightened on the flat surface of the surface 4a of the plate 4 by the heat.

  Thereafter, with the movement of the hair iron 1, the heated hair is transported to the low temperature part TL and immediately cooled. With this cooling, the hair straightened between the plates 4 can be fixed in its shape (straight in this embodiment). In this case, the temperature of the high temperature portion TH is preferably in the range of 80 ° C to 250 ° C, and the temperature of the low temperature portion TL is preferably in the range of -10 ° C to 20 ° C. These temperature ranges are the same in the embodiments described below.

  As described above, in the hair iron 1 of the present embodiment, the high temperature portion TH is formed on the front side of the treatment direction α of the plate 4 and the low temperature portion TL is formed on the rear side of the treatment direction α. A temperature gradient is generated in the plate 4. Therefore, after the hair is heated and corrected at the high temperature portion TH on the front side in the treatment direction α that has become high temperature, the hair can be immediately cooled at the low temperature portion TL on the rear side in the treatment direction α that has become low temperature.

  At this time, since the temperature gradient is generated by providing the high temperature portion TH and the low temperature portion TL on one plate 4 itself having the heater (heating portion) 6, the plate 4 is moved from the surface of the high temperature portion TH to the low temperature portion. The entire surface is continuous across the surface of the TL. Thereby, since it can prevent that a discontinuous part is formed in the surface 4a between the high temperature part TH and the low temperature part TL, it can suppress that a hair is damaged at the time of treatment, and it is performed by smooth operation. Can do.

  Of course, in this case, since the hair heated in the high temperature part TH can be immediately cooled in the low temperature part TL, the corrected hairstyle can be made to last for a long time.

  Further, in the present embodiment, since the heater 6 is arranged on the back surface 4b side of the plate 4 on the front side in the treatment direction α, the high temperature portion TH can be easily formed on the front side in the treatment direction α.

  Furthermore, in this embodiment, since the content rate of the heat insulating material contained in the plate 4 is varied in the treatment direction α, the gradient of the temperature gradient from the high temperature part TH to the low temperature part TL can be adjusted. That is, by gradually increasing the content rate of the heat insulating material from the high temperature part TH side to the low temperature part TL side as in this embodiment, a large temperature gradient is generated in the plate 4 and cooling in the low temperature part TL is performed. The effect can be further enhanced.

  Further, in this embodiment, since the plate 4 that generates the temperature gradient is provided in both of the two clamping portions 2 and 3, when the hair is clamped between the tip portions 2a and 3a of the clamping portions 2 and 3, Furthermore, since heating and cooling can be performed from both sides of the hair, the treatment effect can be further enhanced.

  In the present embodiment, as shown in the upper half of FIG. 3, the content of the heat insulating material of the plate 4 is gradually increased from the high temperature portion TH end to the intermediate portion between the high temperature portion TH and the low temperature portion TL. The intermediate portion to the end of the low temperature portion TL are constant.

  Therefore, when setting hair with the hair iron 1 </ b> A of the present embodiment, when the power cord 9 is inserted into the outlet and the switch 8 is turned on, the heater 6 is heated and a temperature gradient is formed on the plate 4. As a result, as in the first embodiment, it is possible to fix the hairstyle that has been corrected to the desired hairstyle at the high temperature portion TH and that has been immediately cooled and corrected at the low temperature portion TL.

  At this time, in this embodiment, since the radiation fin 10 is provided in the low temperature part TL, the radiation fin 10 can radiate the low temperature part TL side of the plate 4 more effectively.

  Further, since the partition wall 11 is provided in the space S between the high temperature part TH and the low temperature part TL, the heat on the high temperature part TH side is transferred to the low temperature part TL side through the space part S. Can be suppressed.

  Furthermore, since heat exhaust holes 12 are provided at the bottoms of the recesses 2c and 3c at portions corresponding to the heat radiating fins 10, the heat radiated from the heat radiating fins 10 is efficiently discharged from the heat exhaust holes 12 to the outside. it can. Thereby, the heat dissipation effect on the low temperature part TL side of the plate 4 is further enhanced.

  Furthermore, the plate 4 is provided with the partition wall 11 as a heat blocking portion disposed in the space portion S between the high temperature portion TH and the low temperature portion TL, so that the heat on the high temperature portion TH side is lowered through the space portion S. Propagation to the part TL side can be suppressed. Therefore, the cooling effect on the low temperature part TL side of the plate 4 can be further enhanced. This also makes it possible to more reliably fix the hairstyle corrected at the high temperature portion TH.

  Furthermore, by providing the exhaust heat holes 12 as cooling means at the bottoms of the recesses 2c and 3c, the cooling effect on the low temperature part TL side of the plate 4 can be further enhanced, and the hairstyle corrected at the high temperature part TH. Can be fixed more reliably.

  Moreover, in this embodiment, the content rate of the heat insulating material of the plate 4 is gradually increased from the high temperature portion TH end to the intermediate portion between the high temperature portion TH and the low temperature portion TL, and is constant from the intermediate portion to the low temperature portion TL end. Yes. Thereby, since the range of the low temperature part TL can be expanded, the hairstyle which improved and improved the cooling effect of hair can be fixed more reliably.

[Third Embodiment]
FIG. 4 is a diagram showing a third embodiment of the present invention, in which the same components as those in the first and second embodiments are denoted by the same reference numerals and redundant description is omitted.

  The hair iron 1B of the present embodiment is mainly different from the second embodiment in that the plate 4 is recessed in addition to the partition wall 11 serving as a heat blocking part disposed between the high temperature part TH and the low temperature part TL. The groove 13 is provided. In addition, the Peltier element 14 as a cooling means and a heat dissipation fan 15 that enhances the heat dissipation effect of the Peltier element 14 are provided on the back surface 4b side of the plate 4 on the rear side in the treatment direction α.

  The groove 13 is formed by recessing the back surface 4b of the plate 4 and extends in the longitudinal direction of the plate 4. A heat-resistant coat 13a is applied to the inner surface of the groove 13.

  The Peltier element 14 is attached with the cooling side in contact with the back surface 4 b of the plate 4, while the heat dissipation side is positioned in the space S.

  The heat dissipating fan 15 is located in the vicinity of the Peltier element 14 and attached to the back surface 4 b of the plate 4.

  Even in the present embodiment, the partition wall 11 is provided in the space S as in the second embodiment, and the exhaust heat holes 12 are provided in the bottoms of the recesses 2c and 3c. In this case, the partition wall 11 is provided at the side edge on the high temperature portion TH side of the concave groove portion 13, and the heat exhaust hole 12 corresponds to the mounting position of the Peltier element 14 and the heat dissipation fan 15. Is formed.

  Electric components such as the heater 6, the Peltier element 14, and the heat dissipation fan 15 are connected to the control unit 7 through wiring, and power is supplied to each electric component through the control unit 7 by turning on the switch 8. It is like that.

  In the present embodiment, as shown in the upper half of FIG. 4, the content of the heat insulating material of the plate 4 is gradually increased from the high temperature portion TH end to the high temperature portion TH side end of the concave groove portion 13, and the high temperature It is constant from the part TH side end to the low temperature part TL side end of the groove 13. And it is made low gradually from the low temperature part TL side end to the low temperature part TL side end.

  Therefore, when setting hair with the hair iron 1B of this embodiment, the power cord 9 is inserted into an outlet and the switch 8 is turned on. Then, the heater 6, the Peltier element 14 and the heat dissipating fan 15 are energized, the heater 6 heats the high temperature part TH, and the Peltier element 14 cools the low temperature part TL. Further, the heat radiating fan 15 positively moves the hot air generated in the heat radiating portion of the Peltier element 14 toward the heat exhaust hole 12.

  Thereby, since the low temperature part TL can be actively cooled by the Peltier device 14, the temperature gradient generated in the plate 4 can be increased. At this time, the heat radiated from the heat radiating part of the Peltier element 14 is positively exhausted to the outside by the heat radiating fan 15 from the heat exhaust hole 12, and the heat radiation of the Peltier element 14 is suppressed from affecting the low temperature part TL. Will be.

  Further, in the present embodiment, as in the second embodiment, the partition wall 11 is provided in the space portion S, so that the heat on the high temperature portion TH side is transferred to the low temperature portion TL side through the space portion S. Can be suppressed.

  As described above, according to the hair iron 1B of the present embodiment, a temperature gradient can be generated in the plate 4 by the heater 6, so that the same effect as the first embodiment can be obtained.

  Further, in the present embodiment, in addition to the effects of the first embodiment, since the concave groove portion 13 is provided between the high temperature portion TH and the low temperature portion TL, the amount of heat transferred from the high temperature portion TH to the low temperature portion TL is recessed. The groove portion 13 can efficiently cut off. As a result, the temperature gradient of the plate 4 can be further increased, and the hairstyle corrected at the high temperature portion TH can be more reliably fixed.

  Furthermore, since the Peltier element 14 as a cooling means is provided in the low temperature part TL, the low temperature part TL can be actively cooled by the Peltier element 14, and the temperature of the low temperature part TL can be further lowered. This also makes it possible to more reliably fix the hairstyle corrected at the high temperature portion TH.

  Furthermore, since the heat dissipation fan 15 is provided in the vicinity of the Peltier element 14, the heat dissipation efficiency of the Peltier element 14 can be improved and the cooling effect of the Peltier element 14 can be enhanced. Of course, in this case, by providing the heat exhaust hole 12 at the bottom of the recesses 2c and 3c where the heat dissipating fan 15 is opposed, the heat from the Peltier element 14 is actively discharged to the outside from the heat exhaust hole 12. The cooling efficiency of the Peltier element 14 can be further increased.

  Moreover, in this embodiment, since the partition wall 11 is provided in the space part S like the said 2nd Embodiment, the cooling effect by the side of the low temperature part TL of the plate 4 can be heightened more.

  Furthermore, in this embodiment, the content rate of the heat insulating material of the plate 4 is gradually increased from the high temperature portion TH end to the high temperature portion TH side end of the concave groove portion 13 and is constant to the low temperature portion TL side end of the concave groove portion 13. Then, the temperature is gradually lowered to the end of the low temperature part TL.

  Therefore, since the content of the heat insulating material is low in the low temperature part TL where the Peltier element 14 is provided, the cooling temperature by the Peltier element 14 can be efficiently transmitted to the surfaces 2a and 3a of the low temperature part TL. Further, the temperature can be lowered.

[Fourth Embodiment]
5 and 6 are views showing a fourth embodiment of the present invention, in which the same components as those in the first to third embodiments are denoted by the same reference numerals and redundant description is omitted. To do.

  The hair iron 1C of the present embodiment is mainly different from the third embodiment in that temperature sensors 16 and 17 are provided in the high temperature portion TH and the low temperature portion TL, respectively. Based on the detection values of the temperature sensors 16 and 17, the heater 6, the Peltier element 14, and the heat dissipation fan 15 are controlled.

  The temperature sensors 16 and 17 are disposed in the vicinity of both side edges of the recessed groove portion 13, and the detected values of the temperature sensors 16 and 17 are taken into the control unit 7. The control unit 7 controls the current value supplied to the heater 6, the Peltier element 14, and the heat dissipation fan 15.

  For example, two examples of current value control at this time are shown in FIGS.

  In the case of (a), as shown in the upper stage, for example, when the detection value of the temperature sensor 17 rises to T1, as shown in the middle stage, the current value applied to the Peltier element 14 and the heat dissipating fan 15 is changed to the temperature T1. Gradually increase from the time of rising. Thereby, the cooling capacity of the low temperature part TL is increased. Further, as shown in the lower stage, while the current value applied to the heater 6 is gradually increased, the time when the temperature rises to T1 is gradually decreased at the apex. Thereby, the temperature on the high temperature part TH side is lowered.

  (B) is the opposite of (a). When the detected value of the temperature sensor 17 falls to T2 as shown in the upper part, it is applied to the Peltier element 14 and the heat dissipation fan 15 as shown in the middle part. The current value is gradually decreased from the time when the temperature drops to T2. Thereby, the cooling capability of the low temperature part TL is made low. Further, as shown in the lower stage, while the current value applied to the heater 6 is gradually lowered, the time when the temperature falls to T2 is gradually increased as a valley. Thereby, the temperature on the high temperature part TH side is increased. In the graphs (a) and (b), the horizontal axis indicates time in all graphs. In the upper graph, the vertical axis indicates the temperature, and in the middle and lower graphs, the vertical axis indicates the current value.

  Therefore, when setting the hair with the hair iron 1C of the present embodiment, when the power cord 9 is inserted into the outlet and the switch 8 is turned on, the heater 6, the Peltier element 14 and the heat dissipation element are radiated as in the third embodiment. The fan 15 is energized. Then, the high temperature part TH is heated by the heater 6, the low temperature part TL is cooled by the Peltier element 14, and the heat generated in the heat radiating part of the Peltier element 14 is positively exhausted by the heat radiating fan 15. Move in the direction.

  At this time, in the present embodiment, the current applied by the control unit 7 to the heater 6, the Peltier element 14, and the heat dissipation fan 15 based on the detection values of the temperature sensors 16 and 17 provided in the high temperature part TH and the low temperature part TL. Control each value. Thereby, the heating amount of the high temperature part TH by the heater 6, the cooling amount of the low temperature part TL by the Peltier element 14, and the air volume of the heat dissipating fan 15 are precisely controlled.
