Detailed Description

[ first embodiment ]

Embodiments of the present invention will be described in detail below.

(schematic configuration of Hair waving device 1)

The outline of the structure of the hair iron 1 according to the present invention will be described specifically with reference to the drawings. Fig. 1 is an external perspective view of the hair iron 1, in which (a) shows an open state and (b) shows a closed state. Fig. 2 is a side view of the hair iron 1 and shows an open state. Fig. 3 shows a top view of the hair iron 1. Fig. 4 is a sectional view taken along line a-a of the hair iron 1 shown in fig. 3 and shows an opened state.

As shown in fig. 1 (a) and 1 (b), the hair iron 1 has an elongated appearance, and a power cord 3 is connected to one end in the longitudinal direction. Hereinafter, the side of the hair iron 1 to which the power cord 3 is connected is referred to as a "base side", and the opposite side is referred to as a "tip side".

The hair iron 1 includes a first grip body 10 and a second grip body 30 each having an elongated shape. The first grip body 10 and the second grip body 30 are formed in an elongated shape, and outer peripheral surfaces on the opposite sides of surfaces (facing surfaces) facing each other have portions formed in curved surfaces that expand outward. The proximal end side of either the first grip body 10 or the second grip body 30 is expanded outward beyond the distal end side.

Hereinafter, the surfaces of the first grip body 10 and the second grip body 30 facing each other are referred to as "facing surfaces" of the respective members. The surfaces (the outer peripheral surfaces described above) opposite to the facing surfaces are referred to as "back surfaces" of the respective members. That is, fig. 3 is a plan view of the first grip body 10 as viewed from the back side. The surfaces along the longitudinal direction of the first grip body 10 and the second grip body 30 connected to the opposing surfaces and the back surface are referred to as "side surfaces" of each. The direction in which the pair of side surfaces of the first grip body 10 and the second grip body 30 face each other is referred to as a "width direction" or a "short-side direction".

As shown in fig. 2, when viewed from the side of the first grip body 10 and the second grip body 30, the outer ridge lines of the first grip body and the second grip body are gradually inclined so as to be closer to the facing surfaces from the base end side to the substantially central portion in the longitudinal direction, except for the base end side end portion. The ridge line of the second grip body 30 extends flat from the substantially central portion to the distal end portion in the longitudinal direction, and the ridge line of the first grip body 10 temporarily rises through a ridge portion 16a provided in the middle, which will be described later.

As shown in fig. 3, when the first grip body 10 and the second grip body 30 are viewed from the back side of the first grip body 10, the shape is thicker on the base end side except for the base end side end portion, and becomes thinner toward the substantially central portion in the longitudinal direction. Has a constant width from the substantially central portion in the longitudinal direction to the distal end portion.

As shown in fig. 4, the first grip body 10 and the second grip body 30 are connected to the hinge portion 2 at their base end sides. The first grip body 10 and the second grip body 30 are connected to each other so as to be able to open and close in a substantially V-shape between a closed state and an open state with the hinge portion 2 as a base end. The closed state is a state in which the first grip body 10 and the second grip body 30 are closed as shown in fig. 1 (b). The opened state is a state in which the first grip body 10 and the second grip body 30 shown in fig. 1 (a) are opened.

When the user uses the hair iron 1, the first grip body 10 and the second grip body 30 are relatively rotated by gripping a portion from the proximal end side (excluding the end portions) to the substantially central portion in the longitudinal direction of the first grip body 10 and the second grip body 30. Since the hair iron 1 is formed such that a portion where the palm of the hand of the user is located is thick and a portion where the fingers are located is thin, the hair iron 1 is easily gripped and is easily opened and closed. Further, this structure facilitates the opening and closing operation by placing and holding the thumb on the bulge portion 16a described later.

Although not shown, a spring for applying a biasing force in a direction in which the first grip body 10 and the second grip body 30 are expanded away from each other is disposed at a predetermined portion of the first grip body 10 and the second grip body 30 on the proximal end side connected to the hinge portion 2.

As shown in fig. 2, the first grip body 10 includes a first hair holding portion 11 having an elongated shape on the distal end side, and similarly, the second grip body 30 includes a second hair holding portion 31 having an elongated shape on the distal end side. These first hair holding parts 11 and second hair holding parts 31 are paired. The first hair holding part 11 provided on the first grip body 10 includes a first heating plate 12, and the second hair holding part 31 provided on the second grip body 30 includes a second heating plate 32.

As shown in fig. 1 (a), the first hot plate 12 and the second hot plate 32 are both substantially rectangular parallelepiped in shape, and heating elements 40 and 41 are disposed on the back surfaces thereof (see fig. 4). The surfaces of the first heating plate 12 and the second heating plate 32 facing each other are heating surfaces, and the heating surfaces of the first grip body 10 and the second grip body 30 face each other when they are close to each other. When the first and second grip bodies 10 and 30 approach each other, the first and second hair holding portions 11 and 31 hold and heat hair.

The first grip body 10 further includes an air inlet 13 for sucking air, an air outlet 14 for blowing out air, and an operation portion 24. The suction ports 13 are opened on both side surfaces of the base end side of the first grip body 10. The air outlet 14 is formed on the back side of the first grip body 10 and opens sideways. The air outlet 14 has an air outlet structure for blowing air toward the front side having the heating surface of the first heating plate 12, and can blow air toward the front side. The suction port 13 and the discharge port 14 are communicated with each other through a ventilation duct 15 (see fig. 5) described later.

The operation portion 24 is provided adjacent to the suction port 13 on one side surface of the base end side of the first grip body 10. The operation unit 24 can be used to open/close the power supply of the hair iron 1, adjust the set temperatures of the first heating plate 12 and the second heating plate 32, and adjust the volume of air blown out from the air outlet 14.

(detailed constitution of Hair waving device 1)

Next, the detailed configuration of the hair iron 1 will be described with reference to fig. 5 to 9 in addition to fig. 1 to 4. Fig. 5 is an exploded perspective view of the hair iron 1 and shows an opened state. Fig. 6 is a plan view of the hair iron 1 with the first upper case 16 removed, and also shows air branching by the branching portion 23. Fig. 7 is a sectional view of the first grip body 100 taken along line B-B of the hair iron shown in fig. 3, showing in the drawing both the air flow and the arrival area a. Fig. 8 shows a perspective view of a section in the line C-C of the hair iron 1 shown in fig. 3 and shows an opened state. Fig. 9 is a plan view of an enlarged main portion of the first branch rib 23a and the second branch rib 23b provided in the branch portion 23.

As shown in fig. 2 and 4, the second grip body 30 includes a second lower case 36 forming an outer covering of the second grip body 30. The second lower case 36 houses the second hot plate 32, the heating element 41 provided on the rear surface of the second hot plate 32, and the support 43 that supports the second hot plate 32.

On the other hand, as shown in fig. 2, 4 and 5, the first grip body 10 includes a first upper case 16, a first lower case 17, an air duct 15, an air blowing fan 19, a control board 20, a power supply board 21, a charged particle generating device 22, and the like in addition to the first heating plate 12, the air inlet 13, the air outlet 14, and the operation portion 24.

The first upper case 16 and the first lower case 17 are configured to be fitted to each other and form an exterior body of the first grip body 10. The blower fan 19, the control board 20, the power supply board 21, and the charged particle generating device 22 are housed in the first lower case 17. The first heater plate 12 is integrally fitted to the back surface side of the first upper case 16 with a support 42 that supports the heating element 40 and the first heater plate 12 provided on the back surface thereof, and is sandwiched between the first upper case 16 and the first lower case 17.

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

The air duct 15 is configured to communicate the air inlet 13 and the air outlet 14. As shown in fig. 5 and 6, the air blowing duct 15 includes an intake side duct in which the air blowing fan 19 is disposed, and an exhaust side duct 15a provided downstream of the exhaust port 19b of the air blowing fan 19 in the air flow direction. The exhaust-side duct 15a communicates the exhaust port 19b and the blow-out port 14.

The exhaust-side duct 15a is formed by attaching a duct member 18 on the inner surface (back surface) side of the first upper case 16. By using the duct member 18, the exhaust-side duct 15a can be provided separately and independently from the heating mechanism including the first heating plate 12. By the independent arrangement, the influence of the air blowing function on the heating mechanism can be prevented/suppressed. The heating mechanism includes the first heating plate 12, and a heating element 40, a support 42, and the like disposed on the back surface of the first heating plate 12. In the hair iron disclosed in patent document 1, the support of the heating plate serves as a partition wall of the air duct. With such a configuration, the blower function may affect the heater structure to lower the temperature of the heating surface.

The blower fan 19 is disposed in the suction-side duct, i.e., in a position adjacent to the suction port 13. The blower fan 19 is constituted by, for example, a sirocco fan, and includes a fan motor and an impeller 19c, which are not shown. In the impeller 19c, the rotation axis thereof extends in the width direction of the first grip body 10, and the suction port 19a thereof faces the suction port 13. Fig. 5 shows an impeller 19c and a casing 19d for housing the impeller 19 c.

An exhaust port 19b of the blower fan 19 is connected to the exhaust-side duct 15 a. When the impeller 19c is rotated by the fan motor of the blower fan 19, the airflow flows from the suction port 13 to the blow duct 15 toward the blow port 14. In the present embodiment, the blower fan 19 is a sirocco fan, but may be a propeller fan or a turbofan.

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

In the present embodiment, positive and negative voltages formed by an ac waveform or a pulse 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 15 a.

By the corona discharge of the discharge electrode 22a to which a positive voltage is applied, water molecules in the air are ionized and hydrogen ions are generated. The hydrogen ions are clustered with water molecules in the air by solvation energy. Thus, generating a complex of H⁺(H₂O) m (m is 0 or any natural number), and is mixed with the airflow.

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, generating a gas composed of O₂ ^-(H₂And charged particles of negative air ions composed of O) n (n is an arbitrary natural number) and mixed with the air flow. In the present embodiment, the charged particle generator 22 generates positive ions and negative ions, but may generate only positive ions or only negative ions.

In the present invention, the charged particles include charged fine particulate water in addition to air ions. In this case, the charged particle generating device 22 may be configured by, for example, an electrostatic atomizing device. Charged fine particulate water containing a radical component is generated by an electrostatic atomization device. That is, the discharge electrode provided in the electrostatic atomization device is cooled by the peltier element, and condensed water is generated on the surface of the discharge electrode. Then, when a negative high voltage is applied to the discharge electrode, the dew condensation water generates charged fine particulate water containing negative ions. When a positive high voltage is applied to the discharge electrode, the dew condensation water generates charged fine particulate water containing positive ions.

A control board 20 and a power supply board 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 board 21 are arranged in an L shape. The control board 20 is disposed on the back side of the operation portion 24 provided in the first lower case 17, and the power supply board 21 is disposed on the bottom (opposite surface side) of the first lower case 17. The control board 20 is mounted with circuit components such as a microcomputer (not shown), and the power board 21 is mounted with circuit components 27 such as a plurality of capacitors and transformers.

As shown in fig. 6, the exhaust-side duct 15a is divided into four sections, i.e., a first section 15a-1 to a fourth section 15a-4, from the exhaust port 19b of the blower fan 19 toward the downstream side in the air flow direction. The first portion 15a-1 on the most upstream side is disposed in an empty space of the disposition spaces of the control board 20 and the power supply board 21 provided in the L shape. By arranging the control substrate 20 and the power supply substrate 21 in an L-shape and designing the arrangement of circuit components to be mounted, a space for the exhaust-side duct 15a is secured above the power supply substrate 21. The duct width of the first portion 15a-1 is narrower in the width direction than the air outlet 19b of the blower fan 19 so as to be able to be disposed in an empty space.

By narrowing the duct width of the first portion 15a-1 in this manner, the first portion can be disposed in an empty space of the disposition space of the control board 20 and the power supply board 21. Further, by narrowing the duct width and reducing the cross-sectional area of the flow path, the velocity of the air flowing through can be increased.

The duct width of the second portion 15a-2 located on the downstream side in the air flow direction of the first portion 15a-1 is formed to be wider than the first portion 15 a-1. The second portion 15a-2 corresponds to a portion where the discharge electrode 22a of the charged particle generator 22 is inserted from the bottom surface of the duct member 18. By enlarging the duct width of the portion of the charged particle generator 22 where the discharge electrode 22a is located, turbulence is caused in the airflow, and the ions released from the charged particle generator 22 are efficiently drawn into the air flowing through.

The third portion 15a-3 located on the downstream side in the air flow direction of the second portion 15a-2 is narrower in the duct width than the second portion 15 a-2. In this way, the velocity of the circulating air can be increased again by reducing the cross-sectional area of the flow path again at the third portion 15 a-3.

The fourth section 15a-4 located on the downstream side in the air flow direction of the third section 15a-3 is raised so that the bottom surface of the flow path rises toward the front end side as compared with the third section 15 a-3. In fig. 6, a chain line L1 indicates a position where the bulge 16a starts bulging, and a chain line L2 indicates a position where the end of the bulge 16a ends. As shown in fig. 6, the fourth portion 15a-4 corresponds to a position where the swelling portion 16a starts swelling. As a result, the air having increased speed in the third portion 15a-3 can be sent into the bulge portion 16a without decreasing speed.

Further, as shown in fig. 4, the bottom surface of the exhaust-side duct 15a is inclined so that the distance from the rear-surface-side top of the first upper case 16 on which the raised portion 16a is formed becomes shorter as the position of connection from the exhaust port 19b of the blower fan 19 approaches the raised portion 16 a. The air flowing through the exhaust-side duct 15a reaches the top surface 16a-1 (see fig. 7) inside the raised portion 16a at a predetermined angle by rising toward the raised portion 16a at the bottom surface of the exhaust-side duct 15 a.

The raised portion 16a is formed in an elongated 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 from the back side in plan (see fig. 3). Specifically, the ridge portion 16a has a trapezoidal shape in which the side on the tip end side is shorter than the side on the base end side. The raised portion 16a extends to the vicinity of the substantially central portion in the longitudinal direction of the first head holder 11 where the first heater plate 12 is disposed, and is inclined to return to the original height (see fig. 2). The width-directional dimension of the raised portion 16a is formed smaller than the width-directional dimension of the first upper case 16 and also smaller than the width-directional dimension of the first hot plate 12 (see fig. 7).

The air outlet 14 is formed in an elongated shape along the longitudinal direction of the raised portion 16a (the longitudinal direction of the first grip body 10) on both side surfaces of the raised portion 16a, and is opened to the side. The air outlet 14 has an air outlet structure for blowing air toward the front surface side of the first grip 10 having the heating surface of the first heating plate 12, and blows air toward the front surface side of the first grip 10.

Specifically, as shown in fig. 7, the upper edge portion of the opening of the blowout port 14 includes an upward inclined surface portion 25 inclined with respect to the heating surface of the first heating plate 12. The upper inclined surface portion 25 is provided on each of the two positions of the air outlet 14. Further, a lower inclined surface portion 26 connected to the lower edge portion is provided at the lower edge portion of the opening of the air outlet 14. The air flowing through the exhaust-side duct 15a and on the ceiling surface 16a-1 inside the raised portion 16a is guided to the upper inclined surface portion 25 and the lower inclined surface portion 26, and is guided obliquely downward with the heating surface as indicated by arrow Y1. The guided air reaches the hair 60 (the hair held between the first hair holding portion 11 and the second hair holding portion 31) while spreading from the back surface side of the first holding body 10 provided with the air outlet 14 toward the side of the first hair holding portion 11.

In the present embodiment, the inner side of the swelling portion 16a is formed as a branch portion 23 that branches the flow path so that the air is directed toward the two air 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 15 a. The first branch rib 23a and the second branch rib 23b branch the flow path of the exhaust-side duct 15a toward the two outlet ports 14 in the opposite directions to each other.

The first branch rib 23a is located on the upstream side in the air flow direction from the second branch rib 23 b. Therefore, the air that reaches the branching portion 23 is first branched by the first branching rib 23 a. As shown in fig. 4, the first branching rib 23a has a height of about half the height dimension of the space inside the ridge portion 16 a. As shown in fig. 6 and 9, the first branch ribs 23a are inclined toward the front end side as they approach the outlet 14 from the widthwise central portion. As a result, as shown by an arrow Y2 in fig. 6, the lower layer side of the air that reaches the branch portion 23 is guided to the front end side along the inclination of the first branch rib 23a and is inclined to the two air outlets 14.

The air passing through the upper half of the first branching rib 23a reaches the second branching rib 23b provided at the end on the downstream side in the air flow direction, and is branched by the second branching rib 23 b. As shown in fig. 4, the second branching rib 23b is formed to reach the height of the top surface 16a-1 of the inner side of the ridge portion 16a so that all the air reached can be branched. Thus, as shown in fig. 6 and 9, the second branch ribs 23b are inclined toward the front end side as they approach the outlet 14 from the widthwise central portion. As shown by arrow Y3 in fig. 6, the air that has reached the terminal end of the branch portion 23 is thus directed toward the front end side and obliquely guided to the two positions of the air outlet 14.

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

Further, in the present embodiment, as shown in fig. 9, the inclination angle of the first branch rib 23a with respect to a line segment L4 perpendicular to the width direction center line L3 is θ 1, the inclination angle of the second branch rib 23b is θ 2, θ 1 is set to be shallow, and θ 2 is set to be deeper than θ 2. Thus, the area where the air blown out from the air outlet 14 reaches can be secured wider than in the case where θ 1 and θ 2 are equal and θ 1 is deep and θ 2 is shallower.

As shown in fig. 2, the base end side edge of the blowout port 14 is located at the end of the base end side of the first heating plate 12. In other words, the end portion on the base end side of the first heating plate 12 is located on the front end side of the edge on the base end side of the blowout port 14. By setting such a positional relationship, air can be fed more reliably to the hair heated at the end portion on the base end side of the first heating plate 12.

(explanation of the Effect of Hair waving device 1)

The effects of the hair iron 1 having the above-described configuration will be described. According to the hair iron 1, air containing ions can be blown out from the air outlet 14. Accordingly, the hair held by the first and second hair holding portions 11 and 31 is cooled by the heating surfaces of the first and second heating plates 12 and 32, and the static electricity charged to the hair can be removed by the action of the ions.

Fig. 10 is a diagram showing the results of an investigation of the wind speed distribution of air blown out from the outlet port in association with a plan view of the blower 1. In fig. 10, the arrangement position of the first heating plate 12 is indicated by a broken line, and the formation area of the air outlet 14 is indicated by a thick line.

As shown in FIG. 10, the wind with a wind speed of 0.5m/s or more reaches 90mm from the side edges of the first hair holding part 11 and the second hair holding part 31. Further, wind having a wind speed of 0.5m/s or more reaches the tip end portion of the first heating plate 12 from the side surface 40 mm. The wind with a wind speed of 2.5m/s or more also reaches the front end of the first heating plate 12 at the side 90 mm. Thus, wind with a wind speed of 5.5m/s or more reaches an area of 40 to 50mm from the side edge 10 to 30mm and the front end of the first heating plate 12. Preferably, such a region is where the peak of the wind speed is located.

Therefore, by providing the air outlet 14 on the back side, the air arrival area can be made wider than that of the hair iron disclosed in patent document 1. This makes it possible to apply ion-containing air to the hair passing between the first hair holding portion 11 and the second hair holding portion 31 (see fig. 1 a) for a longer period of time than in the conventional art. As a result, the cooling effect is improved, and the same styling performance as that of the conventional one can be ensured even when the set temperature of the heating surface is lower than that of the conventional one with less burden on the hair.

In order to increase the cooling effect and improve the styling performance by widening the reaching area of the air of the hair iron, it is necessary to confirm that the air is blown so that the wind reaches 90mm or more of the side edges of the first hair holding part 11 and the second hair holding part 31 at least at 0.5m/s or more.

Generally, when the set temperature is lowered, the amount of static electricity charged to the hair increases, and styling becomes difficult. However, since the area where the air reaches is wide and the charge removal effect is improved, there is no such problem.

Further, with the above configuration, since the air is not supplied intensively to the vicinity of the heating surface, the heat of the heating surface is suppressed from being taken away by the blown air, and the thermal efficiency can be improved.

Further, by providing the air outlet 14 on the back side, the width (dimension in the short-side direction) of the front end side where the first hair holding portion 11 and the second hair holding portion 31 of the hair iron 1 are provided can be made narrower than the hair iron disclosed in patent document 1. This enables fine modeling to be handled.

Further, in the hair iron 1, the air outlet 14 is provided near the center portion in the longitudinal direction of the first holding body 10 while avoiding the front end side of the first holding body 10, and is configured to blow air toward the front end side of the first holding body 10 on the front side. With such a configuration, the shape of the distal end side of the first grip body 10 can be made smaller, and a finer shape can be handled. Further, the configuration of the front end side of the hair iron is enlarged, but the air outlet 14 may be provided from the front end side of the hair iron.

In the hair iron 1, as shown in fig. 10, wind having a wind speed of 0.5m/s or more reaches the end portion on the front end side of the first heating plate 12 (the end portion on the front end side of the heating surface) from the air outlet 14. Thus, it is possible to treat a fine figure using only the heating surface on the front end side of the hair iron 1.

Here, it is more preferable that the air outlet 14 is provided so that air with an air velocity of 0.5m/s or more also reaches the end on the base end side of the first heating plate 12 (the end on the base end side of the heating surface) from the air outlet 14. Therefore, fine styling from the setting using the front of the heating surface to the use of only the heating surface on the front end side of the hair iron 1 can be handled.

Next, a diagram illustrating the results of investigation of the neutralization effect of hair by using the hair iron 1 of the present embodiment will be described with reference to fig. 11. Fig. 11 is an explanatory diagram showing a difference in hair electrification amount between the hair iron 1 of the present embodiment (example 1) and the hair iron of the comparative example 1. Fig. 11 shows the electrostatic quantity (kV) of hair after scanning.

Three human black hairs were used as samples, and a scanning test was performed for each hair. The test environment was a temperature of 23.5 ℃ and a humidity of 36% RH. The set temperature (temperature of the first heating plate and the second heating plate) of the scanning test was 120 ℃ for the hair iron 1 of the present embodiment (example 1) and 140 ℃ for the hair iron of comparative example 1. The hair iron of comparative example 1 has a structure disclosed in patent document 1.

50cm and 5g of 3-part human black hair were bundled, cut into a length of 30cm from the end, washed with a 1% aqueous solution of sodium lauryl sulfate, and dried. It was confirmed that the static electricity amount of the dried hair was less than 1 kV.

Next, a 30cm tress of hair was scanned once for about 8 seconds. The number of scans is only one. The hair iron 1 of the present embodiment (example 1) was performed at 120 c, and the hair iron of the comparative example 1 (comparative example 1) was performed at 140 c. The electrostatic quantity (kV) of the hair after scanning was measured using FMX-003 manufactured by SIMCO as a measuring instrument. The measurement position was 15cm below the end.

As shown in fig. 11, in the hair iron 1 of the present embodiment, the average static electricity amount of the hair after scanning is 0.537kV when used at 120 ℃. On the other hand, using the hair iron of the prior art as comparative example 1 at 140 ℃, the average electrostatic quantity of the hair after scanning was 0.737 kV. As can be seen from this, the hair iron 1 of the present embodiment has the same or higher static electricity removing force as the hair iron of the related art.

Next, the curling effect caused by the use of the hair iron 1 according to the present embodiment will be described as a result of the examination of the stylability of hair with reference to fig. 12. Fig. 12 is an explanatory view showing a difference in the curl forming force between the hair iron 1 of the present embodiment (example 2) and the hair iron of the comparative example 2. Fig. 12 shows the R-value (mm) of the hair tips after scanning.

Three human black hairs were used as samples, and a scanning test was performed for each hair. The test environment was a temperature of 25.0 ℃ and a humidity of 37% RH. The set temperature (temperature of the first and second heating plates) of the scanning test was 120 ℃ for the hair iron 1 of the present embodiment (example 2) and 140 ℃ for the hair iron of the comparative example 2. The hair iron of comparative example 2 has a structure disclosed in patent document 1.

50cm and 5g of 3-part human black hair were bundled, cut into a length of 30cm from the end, washed with a 1% aqueous solution of sodium lauryl sulfate, and dried. The hair is straightened in advance with respect to the dried hair. The treatment of straightening hair is performed entirely by using the hair iron 1 of the present embodiment.

Next, the hair was sandwiched by plates in a direction perpendicular to the longitudinal direction of the hair, and the 30cm bundle of hair was scanned once (slid in the longitudinal direction of the hair) for about 8 seconds. In both of example 2 and comparative example 2, the grip body side provided with the blow-out port was located inside the curl during scanning. The number of scans is only one. The hair iron 1 of the present embodiment (example 2) was performed at 120 c, and the hair iron of the comparative example 2 (comparative example 2) was performed at 140 c. The R value (mm) of the hair tips after scanning was measured. The measurement position was 15cm below the end.

As shown in fig. 12, in the hair iron 1 of the present embodiment, the average R value of the hair tips after scanning is 71.20mm when used at 120 ℃. On the other hand, in the hair iron of comparative example 2, which is the prior art using 140℃, the average R value of the hair tips after scanning was 72.90 mm. The one with the smaller average R-value of the scanned hair tip enables finer styling. As can be seen from this, in the hair iron 1 of the present embodiment, the curling force can be obtained at a lower setting temperature as much as or higher than that of the hair iron of the related art.

Another embodiment of the present invention will be described below with reference to fig. 13. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.

Fig. 13 is a perspective view showing a cross section of a main part of a hair iron 1A (see fig. 1) according to a second embodiment 2 of the present invention. The hair iron 1A of the present embodiment is configured such that the partition plate 45 is provided in the air intake side duct of the air supply duct 15 in the hair iron 1 of the first embodiment. The partition plate 45 is configured to partition the air flow between the intake-side duct and the gap between the fitted first upper case 16 and first lower case. The partition plate 45 may be provided on the inner wall of the first lower case 17, or may be provided on a side wall of the casing 19d (see fig. 5) of the blower fan 19.

By providing such a partition plate 45, the flow of air sucked into the suction-side duct (air duct 15) from the gap between the first upper case 16 and the first lower case can be blocked. Accordingly, the independence of the air blowing duct 15 can be further improved, and the influence of the air blowing function on the heating mechanism can be more effectively prevented/suppressed.

[ third embodiment ]

Another embodiment of the present invention will be described below with reference to fig. 14. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.

Fig. 14 is a perspective view showing the air supply duct 15 of the hair iron 1B (see fig. 1) according to the third embodiment of the present invention. As shown in fig. 14, the hair iron 1B of the present embodiment is the hair iron 1 of the first embodiment, and the seal 52 is provided at a portion of the pipe member 18 that contacts the inner surface (back surface) side of the first upper case 16 (see fig. 5). The seal 52 is configured to prevent/suppress leakage of air flowing from the exhaust-side duct 15a from the gap between the first upper case 16 and the duct member 18. The seal 52 may also be provided on the inner side (back side) of the first upper case 16.

By providing such a partition, it is possible to prevent/suppress leakage of air flowing from the exhaust-side duct 15a from the gap between the first upper case 16 and the duct member 18. Accordingly, the independence of the air blowing duct 15 can be further improved, and the influence of the air blowing function on the heating mechanism can be more effectively prevented/suppressed.

In addition, according to the hair iron 1A of the second embodiment, it is preferable that a seal is provided also at a position where the partition plate abuts against the inside of the first lower case 17 or the outside of the housing 19d of the air blowing fan 19.

[ fourth embodiment ]

Another embodiment of the present invention will be described below with reference to fig. 15. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.

Fig. 15 is a side view of a hair iron 1C according to a fourth embodiment of the present invention and shows an opened state. As shown in fig. 15, the hair iron 1C of the present embodiment is configured such that, in the hair iron 1 of the first embodiment, an air blowing mechanism including the air inlet 13, the air outlet 14, the air duct 15, the air blowing fan 19, and the like is also provided on the second grip body 30C side. The second lower case 36 of the second grip body 30C is provided with a raised portion 36a, and the air outlet 14 is formed in the raised portion 36 a.

By providing the air blowing function to both the first grip body 10 and the second grip body 30C, the hair heated by the heating surfaces of the first heating plate 12 and the second heating plate 32 is cooled from both the front and back surfaces, and static electricity is removed. This can further improve the cooling and static electricity removing effects, and can provide a hair iron having excellent styling properties, which can easily achieve a desired styling.

[ fifth embodiment ]

Other embodiments of the present invention will be described. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.

The hair iron 1D of the present embodiment is configured to include the charged particle generating device 22 in the hair iron 1 of the first embodiment. Since the charged particle generator 22 is not provided, the air blown out from the air outlet 14 does not contain charged particles. However, as described above, air can be applied to the hairs passing between the first hair holding portion 11 and the second hair holding portion 31 (see fig. 1 a) for a longer time than before. As a result, the cooling effect is enhanced, thereby enhancing the mold holding power and improving the molding property.

The hair irons 1A to 1C according to the second to fourth embodiments may be configured to include the charged particle generating device 22. That is, the charged particle generator 22 is not an essential component in the present invention.

[ conclusion ]

The hair iron 1 to 1D according to the first embodiment of the present invention includes a pair of elongated holding bodies (first holding body 10, second holding body 30) swingably connected to each other, while each of hair holding portions (first hair holding portion 11, second hair holding portion 31) includes a heating surface, at least one of the pair of holding bodies includes an air inlet 13 and an air outlet 14, an air duct 15 communicating the air inlet 13 and the air outlet 14, and an air blowing fan 19 for circulating an air flow through the air duct 15, and the air outlet 14 is provided on a back side of the heating surface of the holding body (first holding body 10) including the air outlet 14 and is open to a side, and has a blowing structure (upper inclined surface portion 25, lower inclined surface portion 26) for blowing air on the front side.

According to the above configuration, air is blown out from the air outlet 14 provided in at least one of the pair of grip bodies. Thus, the hair held between the hair holding portions of the pair of holding bodies and heated by the heating surface can be cooled.

Further, according to the above configuration, the air outlet 14 is provided on the back side of the grip body whose heating surface is the front side and opens to the side, and blows air toward the front side by the blowing structure.

With this configuration, air can be blown to a wider area than a configuration in which the air outlet 14 is provided on the side surface of the grip body. Thus, air can be applied to the hair passing between the hair holding portions of the pair of grip bodies for a longer time than in the conventional art. As a result, the cooling effect is improved, and the molding retention force is improved to improve the moldability.

In the above configuration, since the air is supplied without being concentrated in the vicinity of the heating surface, the blown air can be prevented from carrying away the heat of the heating surface, and the thermal efficiency can be improved.

Further, by providing the air outlet 14 on the back side, the width (dimension in the short-side direction) of the portion of the grip body having the heating surface (the portion having the hair holding portion) can be made narrower than the configuration in which the air outlet is provided on the side surface. This enables fine modeling to be handled.

The hair iron 1 to 1D according to the second aspect of the present invention is further configured such that the hair holding portion is provided on the distal end side opposite to the proximal end side connected to the pair of grip bodies, and the air outlet 14 is provided near the central portion in the longitudinal direction of the grip body while avoiding the distal end side of the grip body.

With the above configuration, the shape of the front end portion of the grip body can be smaller than a configuration in which the air outlet is provided on the back side of the front end portion. This enables finer modeling to be handled.

The hair irons 1 to 1D according to the third aspect of the present invention are further configured such that the air supply duct is provided independently of the heating mechanism including the heating surface.

With the above configuration, the air supply duct 15 is provided independently of the heating mechanism, and the influence of the air supply function on the heater structure can be prevented.

The hair irons 1 to 1D according to the fourth aspect of the present invention are further configured such that the air blown out from the air outlet 14 reaches a side position of the front end side end portion of the heating surface.

With the above configuration, the fine figure can be further processed using the front end portions of the hair irons 1 to 1D.

Further, in the hair iron 1 to 1D according to the fifth aspect of the present invention, the air outlets 14 are provided at two positions on the back side so as to face in opposite directions to each other, the air duct is provided with a branch portion 23 that branches off a flow path so as to direct the air flow that the air blowing fan circulates toward each of the air outlets 14 at the two positions, and the branch portion includes a plurality of branch ribs (a first branch rib 23a and a second branch rib 23b) that are arranged along the air flow direction, are inclined toward the front end sides of the pair of grip portions as approaching the air outlets 14 from the widthwise central portions of the pair of grip portions, and are configured such that the branch rib (the first branch rib 23a) arranged on the upstream side in the air flow direction is lower than the branch rib (the second branch rib 23b) arranged on the downstream side in the air flow direction.

With the above configuration, the air outlet 14 branched into two positions using a plurality of branching ribs can be guided obliquely toward the distal ends of the pair of grip portions.

The hair iron 1D according to the sixth embodiment of the present invention is configured such that the hair iron 1 to 1C includes the charged particle generating device 22 for discharging the charged particles into the air flowing through the air supply duct 15.

According to the above configuration, air containing charged particles having a charge removing effect can be applied to hair held between the hair holding portions of the pair of grips and heated by the heating surface. Further, as described above, air containing charged particles can be applied for a longer time than in the conventional art. This improves the cooling effect and the static elimination effect, and can ensure the same styling performance as the conventional one even if the set temperature of the heating surface is lower than the conventional one with less burden on the hair. If the set temperature is lowered in general, the amount of static electricity charged to the hair increases and styling becomes difficult, but such a problem does not arise by improving the static electricity removal effect.

In the method for setting hair style according to the seventh aspect of the present invention, for hair that is sandwiched and heated by a pair of hair sandwiching portions having a heating surface in a hair iron, the hair is set to a style that air is blown out at an air speed of 0.5m/s or more from an air outlet provided on a back surface side of the hair iron to a side of at least one of the pair of hair sandwiching portions so as to set the hair in a set state with the heating surface as a front surface.

Thus, air can be applied to the hair passing between the hair holding portions of the pair of holding bodies for a longer time than before. As a result, the cooling effect is improved, the mold holding force is improved, and the moldability is improved.

In the method for setting hair style according to the eighth aspect of the present invention, the air having the air velocity of 0.5m/s or more is blown out to reach 90mm or more of the side edge of at least one of the pair of hair holding portions, and the hair style is set.

Thus, air can be applied to the hair passing between the hair holding portions of the pair of grip bodies for a longer time than in the conventional art. As a result, the cooling effect is improved, the mold holding force is improved, and the moldability is improved.

In the method for styling hair according to the ninth aspect of the present invention, the blown air includes charged particles.

According to the above configuration, air containing charged particles having a charge removing effect can be applied to hair held between the hair holding portions of the pair of grips and heated by the heating surface. This improves the cooling effect and the static elimination effect, and can ensure the same styling performance as the conventional one even if the set temperature of the heating surface is lower than the conventional one with less burden on the hair. If the set temperature is lowered in general, the amount of static electricity charged to the hair is increased and styling can be performed, but such a problem does not occur by improving the static electricity removal effect.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments are also included in the technical scope of the present invention. Further, new technical features can be formed by combining the technical means disclosed in the respective embodiments.
