As shown in FIGS. 2 and 4, the second holding body 30 has a second lower case 36 that forms an outer package of the second holding body 30. The second lower plate 36 accommodates the second heater plate 32, the heating element 41 provided on the back surface of the second heater plate 32, and the support 43 for supporting the second heater plate 32.

On the other hand, as shown in FIG. 2, FIG. 4 and FIG. 5, in addition to the first heater plate 12, the suction port 13, the blowout port 14 and the operation portion 24, the first grip body 10 A lower case 17, an air duct 15, an air fan 19, a control board 20, a power supply board 21, a charged particle generator 22 and the like are provided.

The first upper case 16 and the first lower case 17 are fitted together to form an outer package of the first grip body 10. The blower fan 19, the control substrate 20, the power supply substrate 21, and the charged particle generator 22 are accommodated in the first lower case 17. The first heater plate 12 is integrated with a heating element 40 provided on the back surface thereof and a support 42 for supporting the first heater plate 12, and is fitted to the back surface side of the first upper case 16. And the first lower case 17.

The suction port 13 is provided in the first lower case 17. In the suction port 13, a plurality of vent holes 13a opened in the first lower case 17 and a filter (not shown) for collecting dust are disposed. On the other hand, the air outlet 14 is provided in the first upper case 16. The first upper case 16 has a raised portion 16 a that is inclined and raised from a substantially central portion in the longitudinal direction of the first grip body 10, and the air outlet 14 is provided in the raised portion 16 a.

The air duct 15 makes the suction port 13 and the blowout port 14 communicate with each other. As shown in FIGS. 5 and 6, the air duct 15 has an intake side duct in which the air blowing fan 19 is disposed, and an exhaust side duct 15 a provided on the downstream side of the air flow direction from the air outlet 19 b of the air blowing fan 19. . The exhaust side duct 15 a communicates the exhaust port 19 b with the blowout port 14.

The exhaust side duct 15 a is formed by attaching the duct member 18 to the inner surface (rear surface) side of the first upper case 16. By using the duct member 18, the exhaust side duct 15 a can be provided separately from the heating mechanism including the first heater plate 12. By providing them independently, it is possible to prevent / suppress the influence of the air blowing function on the heating mechanism. The heating mechanism includes the first heater plate 12 and the heating element 40 and the support 42 disposed on the back surface thereof. In the hair iron disclosed in Patent Document 1, the support of the heater plate is used as a partition of the air duct. With such a configuration, the blowing function may affect the heating mechanism to lower the temperature of the heating surface.

The blower fan 19 is disposed at a position adjacent to the suction port 13 which is the suction side duct. The blower fan 19 is, for example, a sirocco fan and includes a fan motor and an impeller 19c (not shown). The rotation axis of the impeller 19 c extends in the width direction of the first grip body 10, and the intake port 19 a faces the intake port 13. In FIG. 5, the impeller 19c and the casing 19d for housing the impeller 19c are shown separately.

The exhaust port 19b of the blower fan 19 is connected to the exhaust side duct 15a. When the impeller 19 c is rotated by the fan motor of the blower fan 19, an air flow is distributed to the blower duct 15 from the suction port 13 toward the blower port 14. In the present embodiment, the blower fan 19 is a sirocco fan, but may be a propeller fan or a blower fan type turbo fan.

The charged particle generation device 22 is disposed on the back surface side (bottom surface side) of the exhaust side duct 15 a on the downstream side of the air flow direction of the exhaust port 19 b of the blower fan 19. The charged particle generation device 22 includes a pair of discharge electrodes 22 a used for discharge for releasing the charged particles. The discharge electrode 22 a is inserted into the exhaust side duct 15 a from the back surface side of the duct member 18. The discharge electrode 22a discharges the generated charged particles to the exhaust side duct 15a. Such a charged particle generation device 22 is provided with a pair of discharge electrodes 22a and other electronic components in a housing, and is packaged, for example. The charged particle generator 22 is detachably mounted to the hair iron 1.

In the present embodiment, positive and negative voltages of an alternating current waveform or an impulse waveform are applied to the pair of discharge electrodes 22a, and ions generated by corona discharge of the discharge electrodes 22a are discharged to the exhaust side duct 15a.

Water molecules in the air are ionized by corona discharge of the discharge electrode 22a to which a positive voltage is applied to generate hydrogen ions. These hydrogen ions cluster with water molecules in the air by solvation energy. As a result, charged particles of positive air ions consisting of H ⁺ (H ₂ O) _m (m is 0 or any natural number) are generated and mixed in the air flow.

Further, by the corona discharge of the discharge electrode 22a to which a negative voltage is applied, oxygen molecules or water molecules in the air are ionized to generate oxygen ions. The oxygen ions cluster with water molecules in the air by solvation energy. _{^{Thus, O 2 - (H 2 O}} ) n (n is an arbitrary natural number) are mixed in the negative charged particles in the air ions generated airflow consists. In the present embodiment, although the charged particle generator 22 generates positive ions and negative ions, only positive ions or only negative ions may be generated.

Further, in the present invention, charged particles include charged fine particle water in addition to air ions. At this time, the charged particle generation device 22 may be configured by, for example, an electrostatic atomization device. The electrostatic atomizer generates charged fine particle water containing a radical component. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer with a Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged particulate water containing negative ions is generated from the condensation water. In addition, when a positive high voltage is applied to the discharge electrode, charged particulate water containing positive ions is generated from the condensation water.

A control substrate 20 and a power supply substrate 21 are disposed between the blower fan 19 and the charged particle generator 22. As shown in FIG. 8, the control board 20 and the power supply board 21 are arranged in an L shape. Among them, the control board 20 is disposed on the back side of the operation unit 24 provided in the first lower case 17, and the power supply board 21 is disposed on the bottom (opposite side) of the first lower case 17. There is. Circuit components such as a microcomputer (not shown) are mounted on the control board 20, and circuit components 27 such as a plurality of capacitors and transformers are mounted on the power supply board 21.

As shown in FIG. 6, the exhaust side duct 15a is divided into four portions of a first portion 15a-1 to a fourth portion 15a-4 from the exhaust port 19b of the blower fan 19 toward the downstream side in the air circulation direction. . The most upstream first portion 15a-1 is disposed in an empty space of the L-shaped arrangement of the control board 20 and the power supply board 21. By arranging the control board 20 and the power supply board 21 in an L shape and devising the arrangement of the mounted circuit components, the space of the exhaust side duct 15 a is secured above the power supply board 21. The duct width of the first portion 15a-1 is narrower in the width direction than the exhaust port 19b of the blower fan 19 so as to be able to be disposed in an empty space.

As described above, by narrowing the duct width of the first portion 15a-1, it is possible to arrange the control substrate 20 and the power supply substrate 21 in the vacant space of the arrangement space. Moreover, the speed of the circulating air can be increased by narrowing the duct width to narrow the cross-sectional area of the flow path.

The duct width of the second portion 15a-2 positioned on the downstream side of the first portion 15a-1 in the air flow direction is wider than the first portion 15a-1. The second portion 15 a-2 corresponds to a portion where the discharge electrode 22 a of the charged particle generation device 22 is inserted from the bottom surface of the duct member 18. Thus, by expanding the duct width at the portion where the discharge electrode 22a of the charged particle generation device 22 is located, the air flow is disturbed and the ions released from the charged particle generation device 22 are efficiently distributed to the air. It can be imported.

The third portion 15a-3 located on the downstream side of the second portion 15a-2 in the air circulation direction has the duct width narrowed again than the second portion 15a-2. Thus, the speed of the circulating air can be increased again by narrowing the cross-sectional area of the flow path again in the third portion 15a-3.

The fourth portion 15a-4 located on the downstream side of the third portion 15a-3 in the air flow direction is raised so that the bottom of the flow path climbs toward the tip side more than the third portion 15a-3. Further, in FIG. 6, the alternate long and short dash line L1 is a position where the raised portion 16a starts to be raised, and the alternate long dashed line L2 is a position where the end of the raised portion 16a is shown. As shown in FIG. 6, the fourth portion 15a-4 corresponds to the position where the raised portion 16a starts rising. As a result, the air whose speed has been increased by the third portion 15a-3 can be fed into the raised portion 16a without decreasing the speed.

Furthermore, as shown in FIG. 4, the bottom surface of the exhaust side duct 15 a is formed with the first upper case 16 in which the projecting portion 16 a is formed as it approaches the projecting portion 16 a from the location where the exhaust port 19 b of the blower fan 19 is connected. It inclines so that distance with the back side top of becomes short. The air flowing through the exhaust side duct 15a is angled so that the bottom surface of the exhaust side duct 15a is inclined so as to climb toward such a raised portion 16a, and the top surface 16a inside the convex portion 16a is angled. It reaches -1 (see FIG. 7).

The protruding portion 16a is formed in a longitudinal shape along the longitudinal direction of the first grip body 10, and has a substantially rectangular parallelepiped shape when the first grip body 10 is viewed in plan from the back side (see FIG. 3). In detail, the protruding portion 16 a has a trapezoidal shape in which the side on the distal end side is shorter than the side on the proximal end side. The raised portion 16a is extended to near the approximate center of the longitudinal direction of the first hair gripping portion 11 in which the first heater plate 12 is disposed, and is inclined to return to the original height (see FIG. 2). The dimension in the width direction of the raised portion 16a is smaller than the dimension in the width direction of the first upper case 16 and smaller than the dimension in the width direction of the first heater plate 12 (see FIG. 7).

The blower outlet 14 is formed longitudinally along the longitudinal direction (longitudinal direction of the first gripping body 10) of the protuberance 16a on both side surfaces of such a protuberance 16a, and is opened toward the side. doing. The blowout port 14 has a blowout structure for blowing out air toward the front side of the first holding body 10 with the heating surface of the first heater plate 12, and air toward the front side of the first holding body 10. It can blow out.

Specifically, as shown in FIG. 7, the upper edge portion of the opening of the outlet 14 is provided with an upper slope portion 25 which is inclined with respect to the heating surface of the first heater plate 12. The upper slope portion 25 is provided for each of the two outlets 14. Furthermore, the lower edge portion of the opening of the blowout port 14 is provided with a lower slope portion 26 continuous with the lower edge portion. The air flowing through the exhaust side duct 15a and impinging on the top surface 16a-1 on the inner side of the raised portion 16a is guided by the upper slope portion 25 and the lower slope portion 26 so as to be heated as shown by the arrow Y1. It is guided obliquely downward with a face. The guided air spreads from the back side of the first holding body 10 provided with the outlet 14 toward the side of the first hair holding portion 11 while the hair 60 (first hair holding portion 11 and second hair holding) The hair is held by the part 31).

Furthermore, in the present embodiment, the inside of the raised portion 16a is a branch portion 23 that branches the flow path so as to direct the air to the two outlets 14 provided on both sides. The branch portion 23 has a first branch rib 23a and a second branch rib 23b provided on the bottom surface of the exhaust side duct 15a. The first branch rib 23a and the second branch rib 23b branch the flow path of the exhaust side duct 15a toward the two outlets 14 facing in opposite directions to each other.

The first branch rib 23a is located upstream of the second branch rib 23b in the air circulation direction. Therefore, the air that has reached the branch portion 23 is first branched by the first branch rib 23a. As shown in FIG. 4, the first branch rib 23a has a height about half the height dimension of the space inside the raised portion 16a. And as shown in FIG.6 and FIG.9, the 1st branch rib 23a inclines in the front end side as it approaches the blower outlet 14 from the width direction center part. Thereby, the lower layer side of the air having reached the branch portion 23 is directed to the two outlet ports 14 along the inclination of the first branch rib 23a as shown by the arrow Y2 in FIG. Are guided diagonally.

The upper half of the air having passed through the first branch rib 23a reaches the second branch rib 23b provided at the end of the downstream side in the air flow direction, and is branched by the second branch rib 23b. As shown in FIG. 4, the second branch rib 23b is formed at a height reaching the top surface 16a-1 on the inner side of the raised portion 16a so that all the reached air can be branched. And as shown in FIG.6 and FIG.9, the 2nd branch rib 23b inclines in the front end side as it approaches the blower outlet 14 from the width direction center part. As a result, the air that has reached the end of the branch portion 23 is obliquely guided toward the tip end side to the two outlets 14 as shown by the arrow Y3 in FIG.

Although the configuration in which two branch ribs are provided is shown in the present embodiment, three or more branch ribs may be provided. In that case, the branching rib disposed on the upstream side in the air circulation direction may be configured to be lower than the branching rib disposed on the downstream side in the air circulation direction.

Furthermore, in the present embodiment, as shown in FIG. 9, the inclination angle of the first branch rib 23a with respect to the line segment L4 orthogonal to the width direction center line L3 is θ1, and the inclination angle of the second branch rib 23b is θ2. Then, θ1 is shallow and θ2 is set deeper than this. As a result, compared with the case where θ1 and θ2 are equal or θ1 is deep and θ2 is shallower than this, the reachable area of the air blown out from the blowout port 14 can be secured widely.

The proximal end of the outlet 14 is proximal to the proximal end of the first heater plate 12 as shown in FIG. In other words, the proximal end of the first heater plate 12 is located more distal than the proximal end of the outlet 14. With such a positional relationship, air can be more reliably sent to the hair heated at the proximal end of the first heater plate 12.

(Description of the effect of hair iron 1)
The effect of the hair iron 1 which has the said structure is demonstrated. According to the hair iron 1, air containing ions is blown out from the blowout port 14. As a result, the hair which is held by the first hair holding portion 11 and the second hair holding portion 31 and heated at the heating surfaces of the first heater plate 12 and the second heater plate 32 is cooled, and the action of ions is performed. It is possible to remove static electricity that is charged on the hair.

FIG. 10 is a diagram showing the result of examining the wind speed distribution of the air blown out from the blowout port, in association with the plan view of the hair iron 1. In FIG. 10, the arrangement position of the first heater plate 12 is indicated by a broken line, and the formation region of the outlet 14 is indicated by a thick line.

As shown in FIG. 10, a wind having a wind speed of 0.5 m / s or more has reached 90 mm to the side of the first hair gripping portion 11 and the second hair gripping portion 31. In addition, wind having a wind speed of 0.5 m / s or more reaches the tip of the first heater plate 12 from 40 mm on the side. Wind with a wind speed of 2.5 m / s or more also reaches the tip of the first heater plate 12 with a side of 90 mm. Then, a wind having a wind speed of 5.5 m / s or more reaches an area of 10 to 30 mm on the side and 40 to 50 mm from the tip of the first heater plate 12. It is preferable to locate the peak value of the wind speed in such an area.

Thus, by providing the outlet 14 on the back side, the reachable area of the air can be made wider than the reachable area of the air of the hair iron disclosed in Patent Document 1. As a result, air containing ions can be applied to the hair which has passed between the first hair gripping portion 11 and the second hair gripping portion 31 (see (a) of FIG. 1) for a longer time than in the prior art. Become.
