DESCRIPTION OF EMBODIMENT

[0010] Hereinafter, an embodiment will be described in detail with reference to the drawings. However, unnecessarily detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted.

[0011] The accompanying drawings and the following description are provided to allow those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims.

[0012] The following embodiments and modifications thereof include similar components. Therefore, in the following description, the same components are denoted by the same reference numerals, and redundant description thereof will be omitted.(Embodiment)

[0013] FIG. 1 is a diagram illustrating an example of a hair iron 1 according to an embodiment, and is a diagram schematically illustrating a state in which the hair iron 1 is closed. FIG. 2 is a diagram illustrating an example of the hair iron 1 according to the embodiment, and is a diagram schematically illustrating a state where the hair iron 1 is opened. FIG. 3 is a diagram schematically illustrating a state in which hair H is treated using an example of the hair iron 1 according to the embodiment. The hair iron 1 according to the present embodiment includes a main body part 10 having an elongated shape in one direction (hereinafter referred to as a front-rear direction). As shown in FIGS. 1 and 2, the main body part 10 includes a first arm part 11 and a second arm part 12 which are connected to each other via a hinge part 13 so as to be expandable (openable and closable) in a substantially V shape. By relatively rotating the first arm part 11 and the second arm part 12 via the hinge part 13, the distal ends of the first arm part 11 and the second arm part 12 can be brought into contact with and separated from each other.

[0014] That is, in the present embodiment, a first hair clamping surface (hair clamping surface: hair gripping surface) 1131 and a second hair clamping surface (hair clamping surface: hair gripping surface) 1231, which will be described later, can be brought close to or away from each other with the relative rotation of the first arm part 11 and the second arm part 12.

[0015] The first arm part 11 and the second arm part 12 are provided with a first gripping part (gripping part) 112 and a second gripping part (gripping part) 122 close to the hinge part 13 (on the rear side of the hair iron 1), respectively. A first hair clamping part 113 and a second hair clamping part 123 are provided at the tips of the first arm part 11 and the second arm part 12 (on the front side of the hair iron 1), respectively.

[0016] The first hair clamping part 113 and the second hair clamping part 123 have the first hair clamping surface 1131 and the second hair clamping surface 1231, respectively, which are configured to move toward and away from each other (to face each other) when the first arm part 11 and the second arm part 12 are rotated relative to each other. Specifically, as shown in FIG. 3, when the first arm part 11 and the second arm part 12 are closed, the first hair clamping surface 1131 and the second hair clamping surface 1231 are in contact with each other in a parallel state and are configured to clamp the hair H of a user U. The first hair clamping surface 1131 and the second hair clamping surface 1231 can be formed using, for example, an aluminum plate. At this time, the surface of the aluminum plate is subjected to alumite treatment or glass coating treatment. When alkaline water is used, it is desirable to coat the surface of the aluminum plate with a ceramic, which has higher chemical resistance than glass.

[0017] In the present embodiment, the first hair clamping surface 1131 and the second hair clamping surface 1231 are formed in a substantially rectangular shape elongated in the front-rear direction when viewed along the direction in which the first arm part 11 and the second arm part 12 face each other in the closed state (the normal direction of the first hair clamping surface 1131 and the second hair clamping surface 1231).

[0018] It is preferable that the first hair clamping surface 1131 and the second hair clamping surface 1231 are configured to be floatable by using a float mechanism such as a coil spring, or configured to be flexibly deformable, so that an excessive load can be prevented from being applied to the hair H clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231. Note that the configuration suitable for being flexurally deformed can be formed, for example, by arranging a plurality of plates elongated in the width direction intersecting the front-rear direction so as to be aligned in the front-rear direction, and making each plate independently float in the up-down direction.

[0019] FIG. 4 is a diagram schematically illustrating an example of a liquid discharge part 20 of the hair iron according to the embodiment. In the present embodiment, as shown in FIG. 4, a first heater 114 and a second heater 124 as heating parts are provided on the back side of the first hair clamping part 113 and the second hair clamping part 123 (the side opposite to the first hair clamping surface 1131 and the second hair clamping surface 1231). Both the first hair clamping part 113 and the second hair clamping part 123 do not need to be heated by the heating part, and only one of them may be heated.

[0020] As described above, in the present embodiment, the hair iron 1 includes the main body part 10, and the main body part 10 includes the heating part (the first heater 114 and the second heater 124) and the hair clamping part (the first hair clamping part 113 and the second hair clamping part 123) configured to clamp the hair H in a state of being heated by the heating part.

[0021] In addition, the first arm part 11 and the second arm part 12 include a first housing 111 and a second housing 121, respectively, which form outer shells.

[0022] A power cord (not shown) is attached to a rear end part 10a of the main body part 10 of the hair iron 1. The power cord is electrically connected to a controller 30 that controls the heating part (the first heater 114 and the second heater 124) via a lead wire (wiring) 40.

[0023] Further, the first arm part 11 of the hair iron 1 is provided with an operation switch 14. By operating the operation switch 14, it is possible to switch ON / OFF of energization to the heating part (the first heater 114 and the second heater 124). The heating part (the first heater 114 and the second heater 124) and a sensor, which will be described later, are desirably sealed with a ceramic material such as alumina having alkali corrosion resistance.

[0024] It should be noted that a cordless hair iron can also be provided by incorporating a battery (rechargeable battery) or accommodating a replaceable (non-rechargeable) dry battery in the main body part 10.

[0025] As shown in FIG. 3, when using the above-described hair iron 1, a user U grips the gripping part (the first gripping part 112 and the second gripping part 122), and clamps the hair H between the first hair clamping surface 1131 and the second hair clamping surface 1231. Heat generated by the first heater 114 and the second heater 124 is applied to the hair H through the first hair clamping surface 1131 and the second hair clamping surface 1231 in a state where the hair H is clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231, so that the hair H can be treated (for example, the hair H can be curled or straightened).

[0026] The hair H can be straightened by, for example, pulling down the hair iron 1, in which the root of the hair H is sandwiched between the first hair clamping surface 1131 and the second hair clamping surface 1231, toward the hair end while sliding the hair iron 1 along the hair H.

[0027] As described above, hair iron 1 according to the present embodiment includes the gripping part (the first gripping part 112 and the second gripping part 122) having the hair gripping surface (the first hair clamping surface 1131 and the second hair clamping surface 1231) for gripping the hair H, and the heating part (the first heater 114 and the second heater 124) for heating the hair H gripped by the gripping part (the first gripping part 112 and the second gripping part 122) on the hair gripping surface (the first hair clamping surface 1131 and the second hair clamping surface 1231). The hair iron 1 according to the present embodiment is configured as described above so as to shape the hair H by heat, and hair styling (treatment of the hair H) is performed by shaping the hair H by heat.

[0028] Here, in the present embodiment, it is possible to further improve the treatment effect of the hair H while suppressing thermal damage which the hair H receives from the treatment as much as possible.

[0029] Specifically, as shown in FIG. 4, the hair iron 1 includes the liquid discharge part (generated water discharge part) 20 provided in the main body part 10. The liquid discharge part 20 has a discharge port (generated water discharge part) 21 through which acidic water or alkaline water is discharged to the outside of the main body part 10.

[0030] Further, in the present embodiment, the liquid discharge part 20 includes a storage part (liquid supply tank) 22 configured to store the liquid, a flow path 23 communicating the storage part 22 and the discharge port 21, and the liquid feeding pump (liquid feeding part) 24 with which the flow path 23 is provided and configured to feed the liquid in the storage part 22 toward the discharge port 21.

[0031] For example, raw water such as tap water or well water can be stored in the storage part 22. As a method of supplying the liquid to the storage part 22, for example, there is a method of holding a container constituting the storage part 22 detachably in the main body part 10, removing the container from the main body part 10 to store the liquid, and then attaching the container to the main body part 10. In addition, there is also a method of forming the main body part 10 with an opening which is openably and closably closed by a lid member so as to communicate with the storage part 22, and injecting the liquid from the opening which is opened by removing the lid member to supply the liquid to the storage part 22.

[0032] The liquid such as raw water stored in the storage part 22 is supplied to the discharge port 21 through the flow path 23. As described above, in the present embodiment, the flow path 23 from the storage part 22 to the discharge port 21 is a main flow path 231 of the liquid discharge part 20. That is, the flow path 23 includes one main flow path 231 extending from the storage part 22 to the discharge port 21.

[0033] The liquid feed pump (liquid feeding part) 24 is connected to the flow path 23 downstream of the storage part 22. By driving the liquid feed pump (liquid feeding part) 24, a liquid such as raw water stored in the storage part 22 is fed to the downstream of the flow path 23. The liquid feeding pump (liquid feeding part) 24 is electrically connected to the controller 30 via a wiring (not shown), and power supply and operation (driving) are controlled by the controller 30.

[0034] Further, in the present embodiment, a liquid generation part 25 is disposed downstream of the liquid feeding pump (liquid feeding part) 24 of the flow path 23, and by driving the liquid feeding pump (liquid feeding part) 24, the liquid such as raw water stored in the storage part 22 is supplied to the liquid generation part 25. The liquid generation part 25 generates at least one of acidic water or alkaline water. The acidic water or alkaline water generated by the liquid generation part 25 is sent (fed) to the discharge port 21 by the liquid feeding pump (liquid feeding part) 24 and discharged from the discharge port 21 toward the hair H. At this time, it is preferable that atomized acidic water or alkaline water is discharged from the discharge port 21. The atomization can be performed by, for example, using a blowing port of a spray nozzle as the discharge port 21 or generating ultrasonic atomization using an ultrasonic element. The discharge of the liquid (acidic water or alkaline water) from the discharge port 21 to the hair H can be performed by a continuous operation or an intermittent operation. Such continuous operation or intermittent operation can be controlled by, for example, the controller 30.

[0035] Further, in the present embodiment, as the liquid generation part 25, an ion exchange part 251 configured to perform ion exchange with the liquid passing through the inside thereof is exemplified. That is, the liquid discharge part 20 in which the liquid generation part 25 includes the ion exchange part 251 is exemplified.

[0036] The ion exchange part 251 may include a cation exchange part 2511 having a cation exchange resin regenerated to be of an H-type, or may include an anion exchange part 2512 having an anion exchange resin regenerated to be of an OH-type.

[0037] For example, in a case where the ion exchange part 251 includes the cation exchange part 2511 having a cation exchange resin regenerated to be of an H-type, when a liquid such as raw water is passed through the cation exchange part 2511, cations contained in the liquid such as raw water are ion-exchanged with H ions in the ion exchange resin to generate acidic water.

[0038] On the other hand, in the case where the ion exchange part 251 includes the anion exchange part 2512, when a liquid such as raw water is passed through the anion exchange part 2512, anions contained in the liquid such as raw water are ion-exchanged with OH ions in the ion exchange resin to produce alkaline water.

[0039] As described above, in the present embodiment, the liquid generation part 25 includes the ion exchange part 251 containing the ion exchange resin that generates acidic water or alkaline water. The ion exchange part 251 may include a member configured to perform ion exchange, such as an ion exchange fiber or an ion exchange filter holding an ion exchange resin. That is, the ion exchange part 251 can be formed using at least one kind of member configured to perform an ion exchange among an ion exchange resin, an ion exchange fiber, and an ion exchange filter holding an ion exchange resin.

[0040] In addition, in the present embodiment, a replenishment liquid in which a saline solution as an electrolyte in which the concentration thereof has been adjusted in advance is replenished in tap water is stored in the storage part 22 as raw water. Note that, by supplying raw water to the storage part 22 in which tablet-shaped salt is disposed, the replenishment liquid in which a saline solution is replenished may be generated in the storage part 22. In this way, a liquid to which salt as an electrolyte is added, that is, a liquid in which the amount of dissolved ions is increased is supplied to the liquid generation part 25.

[0041] As described above, in the present embodiment, the ion exchange amount can be adjusted with the electrolyte (salt).

[0042] In this way, even if the water such as tap water is soft water having a small hardness component, it is possible to generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H). That is, even when tap water in a soft water region is used, a necessary amount of acid or alkali liquid can be supplied to the hair H when the hair H is treated using the hair iron 1.

[0043] When the hair H is treated using the hair iron 1 having such a configuration, acidic water or alkaline water is generated and sprayed onto the hair H, and the hair H is subjected to an operation of shaping by heat such as straightening on the heated hair clamping surface (the first hair clamping surface 1131 and the second hair clamping surface 1231).

[0044] Specifically, when the power is turned on by operating the operation switch 14, the liquid feeding pump (liquid feeding part) 24 is driven by the controller 30. When the liquid feeding pump (liquid feeding part) 24 is driven by the controller 30, the NaCl aqueous solution (aqueous solution in which NaCl as an electrolyte is dissolved) stored in the storage part 22 is supplied to the ion exchange part 251 as the liquid generation part 25.

[0045] At this time, in a case where the ion exchange part 251 includes the cation exchange part 2511 having the cation exchange resin regenerated to be of an H-type, since the cation exchange resin inside is strongly acidic by being substituted to be of a H-type, the pH of the liquid is lowered by ion exchange between Na +< of the NaCl aqueous solution and H +< bonded to the cation exchange resin, and acidic water is generated.

[0046] Then, the acidic water generated in the ion exchange part 251 is sprayed from the discharge port 21 toward the hair H. At this time, the acidic water is preferably sprayed toward the hair ends of the hair H clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231. In this way, when the operation of sliding down the hair iron 1 toward the hair ends is performed, the acidic water is attached to hair H before being clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231. Therefore, when the hair H is clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231 for treatment, the ionic bond of the hair H is broken by the acidic water. Therefore, even if the hair H is very unruly, the treatment effect on the hair H can be further improved.

[0047] On the other hand, in a case where the ion exchange part 251 includes the anion exchange part 2512 having the anion exchange resin regenerated to be of an OH-type, since the anion exchange resin inside is strongly basic by being substituted to be of an OH-type, the pH of the liquid is increased by ion exchange between Cl -< of the NaCl aqueous solution and OH -< bonded to the anion exchange resin, and alkaline water is generated.

[0048] Then, the alkaline water generated in the ion exchange part 251 is sprayed from the discharge port 21 toward the hair H. In this way, the hair H in which ionic bonds have been broken by the alkaline water is clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231 for treatment. Therefore, even if the hair H is very unruly, the treatment effect on the hair H can be further improved.

[0049] As described above, in the present embodiment, when the hair H is treated using the hair iron 1, the acidic water or the alkaline water is discharged from the discharge port 21 toward the hair H, and the hair H can be treated in a state where the acidic water or the alkaline water is attached to the hair H.

[0050] The acidic water or the alkaline water is attached to the hair H, so that the ionic bonds of the amino acids of the hair H are broken by the acidic water or the alkaline water. In this manner, when the ionic bonds of the amino acids of the hair H are broken, the cuticle of the hair H is opened, and thus the hair H can be in a state in which the hair is easily shaped. That is, the hair H can be easily treated so as to have a desired shape.

[0051] The hair H in such a state can be clamped by the hair clamping part (the first hair clamping part 113 and the second hair clamping part 123) heated by the heating part, and then, the hair H can be treated. In this way, even if the hair H is very unruly, the hair H can be more reliably formed into a desired shape.

[0052] The hair H in such a state is clamped by the hair clamping part (the first hair clamping part 113 and the second hair clamping part 123) heated by the heating part and treated. In this way, the hair H can be more reliably formed into a desired shape, even if the hair H is very unruly.

[0053] As described above, by using the hair iron 1 according to the present embodiment, the treatment effect on the hair H can be further improved.

[0054] Furthermore, by using the hair iron 1 shown in the present embodiment, the hair H can be treated in a state in which ionic bonds are broken in advance by the acidic water or the alkaline water. Therefore, even when the temperature of the hair clamping part (the first hair clamping part 113 and the second hair clamping part 123) is lower than usual, the treatment effect on the hair H can be further improved. This makes it possible to treat the hair H with less thermal damage.

[0055] As described above, the hair iron 1 according to the present embodiment can improve the treatment effect on hair H while suppressing thermal damage which the hair H receives from treatment as much as possible.

[0056] At this time, if the alkaline water is attached to the hair H, a cuticle layer can be swelled by the alkali, so that the alkali can further permeate the inside of the hair H. As a result, the ionic bonds of the amino acids are also broken inside the hair H, and the treatment effect can be further improved even for more unruly hair.

[0057] Further, if the acidic water is attached to the hair H, cations contained in the liquid such as raw water are ion-exchanged with H ions in the ion exchange resin when the acidic water is generated, so that Ca ions contained in the liquid such as raw water can be removed. As a result, adhesion of Ca to a damaged part of the hair H is suppressed, and the stiffness of the hair H can be further reduced.

[0058] Further, in the present embodiment, the storage part 22 is configured to store liquid, and even when only the hair iron 1 is used, acidic water or alkaline water can be attached to the hair H during treatment of the hair H. In this way, for example, even in a case where the hair iron 1 alone in which the liquid is stored in the storage part 22 is carried to a destination for travel and used, acidic water or alkaline water can be attached to the hair H during treatment of hair H, and usability of the hair iron 1 can be further improved.

[0059] In the present embodiment, the amount of ions dissolved in raw water can be increased by using an electrolyte (salt) containing no Ca. In this way, acidic water or alkaline water can be generated using a liquid having a small amount of dissolved Ca ions. This makes it possible to suppress precipitation of CaCO 3 scale in an alkaline state when an OH-type ion exchange resin is used.

[0060] When an H-type ion exchange resin is used, Ca ions are removed (ion exchanged with H ions) during the generation of acidic water, and thus a liquid (acidic water) containing less Ca can be supplied to the hair H.

[0061] In the present embodiment, as a method of increasing the amount of ions dissolved in the raw water, a method of storing, in the storage part 22, a replenishment liquid in which a saline solution as an electrolyte in which the concentration thereof has been adjusted in advance is replenished in the tap water is exemplified. However, the amount of ions dissolved in the raw water can be increased by various methods.

[0062] For example, the liquid discharge part 20 can include an electrolyte storage part (electrolyte addition part) 26 that is disposed upstream of the liquid generation part 25 and can add an electrolyte (salt) to the liquid. FIG. 5 is a diagram schematically illustrating a first modification of the liquid discharge part 20 according to the embodiment. Specifically, as shown in FIG. 5, an electrolyte storage part (electrolyte addition part) 26 in which an electrolyte (salt) is stored is disposed between the liquid feed pump (liquid feeding part) 24 and the liquid generation part 25, and a liquid to which the electrolyte (salt) is added through the electrolyte storage part (electrolyte addition part) 26 can be supplied to the liquid generation part 25.

[0063] FIG. 6 is a diagram schematically illustrating a second modification of the liquid discharge part 20 according to the embodiment. As shown in FIG. 6, an introduction path 232 communicating with the electrolyte storage part (electrolyte addition part) 26 may communicate with the flow path 23 between the liquid feed pump (liquid feeding part) 24 and the liquid generation part 25, and the electrolyte (salt) stored in the electrolyte storage part (electrolyte addition part) 26 may be introduced into the flow path 23 via the introduction path 232, so that the liquid to which the electrolyte (salt) is added may be supplied to the liquid generation part 25. In this case, the introduction of the electrolyte (salt) into the flow path 23 can be performed by a continuous operation or an intermittent operation. Such continuous operation or intermittent operation can be controlled by, for example, the controller 30.

[0064] In addition, when the generated acidic water or alkaline water is discharged from the discharge port (generated water discharge part) 21 toward the hair H, it is also possible to adopt a configuration in which control is performed such that the generated acidic water or alkaline water is selected and discharged at an appropriate timing according to the state of the hair H.

[0065] The electrolyte added to the liquid is not limited to salt, and various electrolytes can be added to the liquid. For example, various electrolyte (neutral salt electrolytes) such as potassium chloride, sodium carbonate, sodium sulfate, and copper chloride can be added to the liquid. At this time, one kind of electrolyte may be added to the liquid, or a plurality of kinds of electrolytes may be added to the liquid.

[0066] FIG. 7 is a diagram schematically illustrating a third modification of the liquid discharge part 20 according to the embodiment. As shown in FIG. 7, the liquid discharge part 20 may include a water quality determination part 28 that determines the hardness of the liquid to be introduced into the liquid generation part 25, and the electrolyte storage part (electrolyte addition part) 26 that is disposed upstream of the liquid generation part 25 and can add an electrolyte to the liquid.

[0067] As the water quality determination part 28, for example, a hardness sensor that measures the hardness of the liquid can be used. The water quality determination part 28 may include a hardness sensor and a hardness / softness determination part that determines whether the liquid to be introduced into the liquid generation part 25 is soft water or hard water based on the hardness measured by the hardness sensor.

[0068] Then, it is also possible to adopt a configuration in which an appropriate method of supplying the electrolyte is controlled on the basis of the hardness determination result of the liquid by the water quality determination part 28. Such control can also be performed by the controller 30. For example, when the water quality determination part 28 includes the hardness sensor and the hardness / softness determination part, it is possible to perform control such that the electrolyte is added in an appropriate manner based on the determination by the hardness / softness determination part (determination of whether the water is soft water or hard water). Such a hardness / softness determination part can be provided in the controller 30.

[0069] In this way, it is possible to introduce a liquid having a more appropriate hardness into the liquid generation part 25, and thus it is possible to more reliably generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H).

[0070] In addition, as a method of controlling an appropriate manner of supplying the electrolyte by the controller 30, there is a method of adjusting the amount of the electrolyte to be added based on the hardness determination result of the liquid by the water quality determination part 28.

[0071] In addition, there is also a method of adjusting the kind of electrolyte to be added based on the hardness determination result of the liquid by the water quality determination part 28. At this time, one kind of electrolyte may be selected and added, or a plurality of kinds of electrolytes may be selected and mixed at an appropriate ratio and added.

[0072] The hair iron 1 may include a hair state detector that detects the state of the hair H. The detection of the state of the hair H by the hair state detector can be performed by, for example, detecting the pH of the hair surface by using a pH sensor to collect information on the deviation from the isoelectric point in a stable state in advance. In addition, it can also be performed by a conventionally known method such as image diagnosis using an imaging device such as a camera. In addition, the hair state detector can detect, as the state of the hair H, the strength of the unruliness of the hair H, such as the degree of curvature of the hair H, for example.

[0073] Then, based on the detection result (the state of the hair H) of the hair state detector, it is also possible to adopt a configuration in which an appropriate way of supplying the electrolyte is controlled. Such control can also be performed by the controller 30.

[0074] As a method of controlling the manner of supplying an appropriate electrolyte by the controller 30, there is a method of adjusting the amount of electrolyte to be added based on the detection result (the state of the hair H) of the hair state detector.

[0075] There is also a method of adjusting the kind of electrolyte to be added based on the detection result (the state of the hair H) of the hair state detector. At this time, one kind of electrolyte may be selected and added, or a plurality of kinds of electrolytes may be selected and mixed at an appropriate ratio and added.

[0076] Also in this case, a liquid having a more appropriate hardness can be introduced into the liquid generation part 25, and thus it is possible to more reliably generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H).

[0077] It is also possible to provide the hair state detection part and to provide the hair iron 1 with an acidity / alkalinity control part that controls the acidity of the generated acidic water or the alkalinity of the generated alkaline water on the basis of the detection result (the state of the hair H) of the hair state detection part, so that the acidic water having a more appropriate acidity or the alkaline water having a more appropriate alkalinity is released to the hair H.

[0078] It is also possible to use a liquid to which no electrolyte needs to be added.

[0079] For example, it is also possible to generate acidic water or alkaline water using hard water containing a large amount of hardness components such as Ca and Mg.

[0080] However, when the alkaline water is generated using hard water containing a large amount of hardness components such as Ca and Mg, CaCO 3 scale may be precipitated or Ca may adhere to the damaged part of the hair H.

[0081] FIG. 8 is a diagram schematically illustrating a fourth modification of the liquid discharge part 20 according to the embodiment. When hard water containing a large amount of hardness components such as Ca and Mg is used, as shown in FIG. 8, it is preferable to provide a hardness component removal part 27 configured to remove the hardness components of the liquid upstream of the liquid generation part 25 of the flow path 23.

[0082] The hardness component removal part 27 can be formed by using a cation exchange resin regenerated to be of an Na-type. That is, the hardness component removal part 27 can have the cation exchange resin regenerated to be of an Na-type.

[0083] In this way, when the liquid (hard water) such as tap water is passed through the hardness component removal part 27, the hardness component (for example, Ca ions or Mg ions) contained in the liquid such as tap water is ion-exchanged with Na ions in the ion exchange resin, and the hardness component (for example, Ca ions or Mg ions) is removed. Therefore, even when hard water containing a large amount of hardness components is used, it is possible to suppress precipitation of CaCO 3 scale in an alkaline state and adhesion of Ca to the damaged part of the hair H.

[0084] In this way, the hardness component removal part 27 having the cation exchange resin regenerated to be of an Na-type can remove the hardness component (for example, Ca ions or Mg ions) contained in water such as tap water with simplifying the configuration.

[0085] However, when the liquid such as tap water is high-hardness water having a very large amount of hardness components, acidic water having an excessively low pH or alkaline water having an excessively high pH is generated.

[0086] FIG. 9 is a diagram schematically illustrating a fifth modification of the liquid discharge part 20 according to the embodiment. In the case of using high-hardness water containing a very large amount of hardness components, as shown in FIG. 9, the flow path 23 preferably includes a bypass flow path 233 that branches off from the main flow path 231 downstream of the hardness component removal part 27, bypasses the liquid generation part 25, and joins the main flow path 231 downstream of the liquid generation part 25.

[0087] In this way, the acidic water or the alkaline water generated by passing through the liquid generation part 25 and the liquid passing through the bypass flow path 233 can be mixed to dilute the acidic water or the alkaline water. Therefore, even when acidic water or alkaline water is generated using high-hardness water, it is possible to generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H).

[0088] Thus, when the flow path 23 includes the bypass flow path 233, even if the liquid such as tap water is high-hardness water having a very large amount of hardness components, it is possible to generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H). As a result, even when high-hardness water is used, it is possible to prevent an excessive load due to an acid or an alkali from being applied to hair H, and it is possible to suppress thermal damage to the hair H as much as possible during treatment using the hair iron 1.

[0089] Further, it is also possible to provide the hair iron 1 that releases both acidic water and alkaline water to the hair H when the hair H is treated. FIG. 10 is a diagram schematically illustrating a sixth modification of the liquid discharge part 20 according to the embodiment.

[0090] For example, as shown in FIG. 10, the discharge port 21 may include a first discharge port 211 through which acidic water is discharged to the outside of the main body part 10 and a second discharge port 212 through which alkaline water is discharged to the outside of the main body part 10. It is preferable that the first discharge port 211 and the second discharge port 212 are formed at positions as far away from each other as possible in the main body part 10 so that the acidic water and the alkaline water sprayed from the respective discharge ports are prevented from being mixed and neutralized before adhering to the hair. FIG. 10 illustrates an example in which the first discharge port 211 is provided at the tip of the first hair clamping part 113, and the second discharge port 212 is provided close to the second gripping part 122 of the second hair clamping part 123.

[0091] The flow path 23 includes a first flow path 234 connected to the first discharge port 211 and a second flow path 235 connected to the second discharge port 212.

[0092] Thus, after the hair H is treated with the acidic water or the alkaline water, the acidic water and the alkaline water remaining on the hair H can be neutralized. In this way, it is possible to prevent the hair H from remaining in the acid state or the alkaline state as in the case where the treatment of the hair H is performed using only one of the acidic water and the alkaline water.

[0093] Therefore, as illustrated in FIG. 10, when the hair H is treated using the acidic water and the alkaline water, it is possible to apply, to the hair H, a so-called rinsing effect in which the acidic water and the alkaline water remaining on the hair H are neutralized after the hair H is treated and the state of the hair H is set to a normal state (weakly acidic state, which is the isoelectric point of healthy hair H).

[0094] FIG. 11 is a diagram schematically illustrating a seventh modification of the liquid discharge part 20 according to the embodiment. FIG. 10 illustrates an example in which the first flow path 234 and the second flow path 235 are independent flow paths and the acidic water and the alkaline water are individually generated. However, as illustrated in FIG. 11, it is also possible to adopt a configuration in which the flow path 23 is branched in the middle and an electrolytic liquid generation part 252 configured to generate both the acidic water and the alkaline water is disposed at the branched part.

[0095] That is, the liquid generation part 25 may include the electrolytic liquid generation part 252 that generates the electrolytic liquid by electrolyzing the supplied liquid. The flow path 23 may include an introduction path 236 communicating with the electrolytic liquid generation part 252 upstream of the electrolytic liquid generation part 252, the first flow path 234 communicating with a part (an acidic water discharge path 2521) of the electrolytic liquid generation part 252 where the acidic water is generated, and the second flow path 235 communicating with a part (an alkaline water discharge path 2522) of the electrolytic liquid generation part 252 where the alkaline water is generated.

[0096] This makes it possible to reduce the number of components of the liquid discharge part 20 which can apply the rinsing effect to the hair H. This makes it possible to simplify the configuration of the liquid discharge part 20 which can apply the rinsing effect to the hair H.

[0097] It is also possible to provide the liquid discharge part 20 having a plurality of paths in the main body part 10 of the hair iron 1 so that any one of the paths can be selected.

[0098] For example, the liquid discharge part 20 as shown in FIG. 12 can also be provided. FIG. 12 is a diagram schematically illustrating an eighth modification of the liquid discharge part 20 according to the embodiment.

[0099] FIG. 12 illustrates an example in which any one of the path illustrated in FIG. 4, the path illustrated in FIG. 8, and the path illustrated in FIG. 9 can be selected.

[0100] Specifically, an on-off valve 29 formed of an electromagnetic valve is disposed at a branch point located downstream of the liquid feeding pump (liquid feeding part) 24 of the flow path 23. The on-off valve 29 is electrically connected to the controller 30 via the wiring 40, and is controlled by the controller 30 so that only one of the paths is opened.

[0101] Another on-off valve 29 formed of an electromagnetic valve and the like is also disposed at a branch point on the upstream side of the bypass flow path 233. The on-off valve 29 is also electrically connected to the controller 30 via the wiring 40, and is controlled by the controller 30 so that only one of the paths is opened.

[0102] Further, still another on-off valve 29 formed of an electromagnetic valve is also disposed at a junction located upstream of the discharge port 21. The on-off valve 29 is also electrically connected to the controller 30 via the wiring 40, and is controlled by the controller 30 so that only one of the paths is opened. In this way, the flow into the other paths is suppressed.

[0103] The controller 30 controls the opening and closing of each of the on-off valves 29 to select one of the paths shown in FIGS. 4, 8, and 9. The selection of the path can be performed, for example, by operating a mode selection switch provided in the main body part 10. In addition, a sensor may be provided in the storage part 22, and an optimal path may be selected by the controller 30 based on a measurement result of at least one of hardness and pH by the sensor.

[0104] In FIG. 12, the liquid feeding pump (liquid feeding part) 24 is also electrically connected to the controller 30 via the wiring 40, and the driving of the liquid feeding pump (liquid feeding part) 24 is controlled by the controller 30.[Functions and Effects]

[0105] Hereinafter, a characteristic configuration of the hair iron shown in the above embodiment and the modifications thereof and effects obtained thereby will be described.

[0106] (Technique 1) A hair iron 1 described in the above embodiment and modifications thereof includes a main body part 10. The main body part 10 includes a heating part (a first heater 114 and a second heater 124) and a hair clamping part (a first hair clamping part 113 and a second hair clamping part 123) configured to clamp hair H in a state where being heated by the heating part.

[0107] The hair iron 1 further includes a liquid discharge part 20 with which the main body part 10 is provided and which includes a discharge port 21 through which acidic water or alkaline water is discharged to an outside of the main body part 10.

[0108] When the hair H is treated using such a hair iron 1, the hair H can be treated in a state in which the acidic water or the alkaline water is attached to the hair H.

[0109] In this way, since the acidic water or the alkaline water is attached to the hair H, the ionic bond of the amino acid of the hair H is cut by the acidic water or the alkaline water, and cuticle of the hair H is opened. Therefore, the state of the hair H can be a state in which the hair is easily shaped. That is, the hair H can be easily treated so as to have a desired shape.

[0110] When the hair H in such a state is clamped by the hair clamping part (the first hair clamping part 113 and the second hair clamping part 123) heated by the heating part and treated, the hair H can be more reliably formed into a desired shape, even if the hair H is very unruly.

[0111] As described above, the hair iron 1 described in the above embodiment and the modification thereof is used to further improve the treatment effect on the hair H.

[0112] Furthermore, when the hair iron 1 described in the above embodiment and the modification thereof is used, the treatment of the hair H can be performed in a state where the ionic bond is cut in advance by the acidic water or the alkaline water. Therefore, even when the temperature of the hair clamping part (the first hair clamping part 113 and the second hair clamping part 123) is lower than usual, the treatment effect on the hair H can be further improved. This makes it possible to treat the hair H with less thermal damage.

[0113] As described above, the hair iron 1 according to the embodiment and the modification thereof can improve the treatment effect on the hair H while suppressing thermal damage which the hair H receives from the treatment as much as possible.

[0114] (Technique 2) In the above Technique 1, the liquid discharge part 20 may include a storage part 22 configured to store the liquid and a flow path 23 communicating the storage part 22 and the discharge port 21. Furthermore, the liquid discharge part 20 may include a liquid feeding pump (liquid feeding part) 24 that is provided in the flow path 23 and configured to feed the liquid in the storage part 22 toward the discharge port 21.

[0115] With such a configuration, when the liquid is stored in the storage part 22, acidic water or alkaline water can be attached to the hair H during treatment of the hair H even when only the hair iron 1 is used. In this way, for example, even in a case where the hair iron 1 alone in which the liquid is stored in the storage part 22 is carried to a travel destination and used, the acidic water or the alkaline water can be attached to the hair H at the time of the treatment of the hair H, and thus the usability of the hair iron 1 can be further improved.

[0116] (Technique 3) In addition, in the above Technique 2, the liquid discharge part 20 may include a liquid generation part 25 that is provided in the flow path 23 and is configured to generate at least one liquid of acidic water or alkaline water.

[0117] With such a configuration, the acidic water or the alkaline water can be attached to the hair H during treatment of the hair H only by storing tap water in the storage part 22. That is, the acidic water or the alkaline water is generated in the liquid generation part 25 using water such as tap water, and the generated acidic water or alkaline water can be attached to the hair H during the treatment using the hair iron 1. In this way, for example, even in a case where the hair iron 1 alone is carried to a travel destination and used, the acidic water or the alkaline water can be attached to the hair H at the time of the treatment of the hair H using water at the travel destination, and thus the usability of the hair iron 1 can be further improved.

[0118] (Technique 4) In the above Technique 3, the liquid generation part 25 may include an ion exchange part 251.

[0119] In this way, it is possible to generate the acidic water or the alkaline water only by passing water such as tap water through the ion exchange part 251. Therefore, it is possible to simplify the configuration and to more easily generate the acidic water or the alkaline water using water such as tap water.

[0120] (Technique 5) In the above Technique 4, the ion exchange part 251 may include a cation exchange part 2511 including a cation exchange resin regenerated to be of an H-type.

[0121] In this way, when water such as tap water is passed through the cation exchange part 2511, cations contained in the water such as tap water and H ions in the ion exchange resin are ion-exchanged to generate acidic water. Therefore, when the ion exchange part 251 includes the cation exchange part 2511, acidic water can be generated only by passing water such as tap water through the cation exchange part 2511. Thus, it is possible to simplify the configuration and to generate the acidic water more easily using water such as tap water.

[0122] If cations contained in water such as tap water are ion-exchanged with H ions in the ion exchange resin, Ca ions contained in water such as tap water can be removed. As a result, adhesion of Ca to the damaged part of the hair H is suppressed, and the stiffness of the hair H can be further reduced.

[0123] In addition, when the ion exchange part 251 includes the cation exchange part 2511, it is possible to further improve the treatment effect even in the case of extremely unruly hair.

[0124] (Technique 6) In the above Technique 4 or Technique 5, the ion exchange part 251 may include an anion exchange part 2512 including an anion exchange resin regenerated to be of an OH-type.

[0125] In this way, when water such as tap water is passed through the anion exchange part 2512, anions contained in the water such as tap water are ion-exchanged with OH ions in the ion exchange resin to generate alkaline water. Therefore, when the ion exchange part 251 includes the anion exchange part 2512, it is possible to generate alkaline water only by passing water such as tap water through the anion exchange part 2512. Thus, it is possible to simplify the configuration and to more easily generate alkaline water using water such as tap water

[0126] In addition, when the alkaline water is attached to the hair H, the cuticle layer can be swollen by the alkali, so that the alkali can further permeate the inside of the hair H. As a result, the ionic bond of the amino acid is also broken inside the hair H, and the treatment effect can be further improved even for extremely unruly hair.

[0127] (Technique 7) In any one of Techniques 3 to 6, a liquid to which an electrolyte has been added may be supplied to the liquid generation part 25.

[0128] In this way, the amount of ion exchange can be adjusted by the electrolyte. Therefore, even if the water such as tap water is soft water having a small hardness component, it is possible to generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H).

[0129] As described above, when the liquid to which the electrolyte has been added is supplied to the liquid generation part 25 to generate the acidic water or the alkaline water, even in a case where tap water in a soft water region is used, it is possible to supply a necessary amount of the acidic or alkaline liquid to the hair H when the hair H is treated using the hair iron 1.

[0130] (Technique 8) In the above Technique 7, the electrolyte may be salt.

[0131] In this case, since the electrolyte does not contain Ca, acidic water or alkaline water can be produced using a liquid containing a small amount of Ca ions. Therefore, when an OH-type ion exchange resin is used, precipitation of CaCO 3 scale in an alkaline state can be suppressed.

[0132] When an H-type ion exchange resin is used, Ca ions are removed (ion exchanged with H ions) when the acidic water is generated, and thus a liquid (acidic water) containing less Ca can be supplied to the hair H.

[0133] In addition, when salt is used as the electrolyte, it is possible to further improve the treatment effect even for extremely unruly hair.

[0134] (Technique 9) In the above Technique 7 or Technique 8, the liquid discharge part 20 may include a water quality determination part 28 that determines hardness of the liquid to be introduced into the liquid generation part 25, and an electrolyte storage part (electrolyte addition part) 26 that is disposed upstream of the liquid generation part 25 and is configured to add an electrolyte to the liquid. The hair iron 1 may adjust the amount of electrolyte to be added based on the result of determination of the hardness of the liquid by water quality determination part 28.

[0135] In this way, it is possible to introduce a liquid having a more appropriate hardness into the liquid generation part 25, and thus it is possible to more reliably generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H).

[0136] (Technique 10) In any one of Techniques 3 to 9, a hardness component removal part 27 configured to remove a hardness component of the liquid may be provided upstream of the liquid generation part 25 in the flow path 23.

[0137] This makes it possible to supply the liquid from which ions of Ca and Mg have been removed to the liquid generation part 25. Therefore, even when hard water containing a large amount of hardness components is used, it is possible to suppress precipitation of CaCO 3 scale in an alkaline state.

[0138] (Technique 11) In the above Technique 10, the hardness component removal part 27 may have a cation exchange resin regenerated to be of an Na-type.

[0139] In this way, when water such as tap water is passed through the hardness component removal part 27, the hardness component (for example, Ca ions or Mg ions) contained in the water such as tap water is ion-exchanged with Na ions in the ion exchange resin, and the hardness component (for example, Ca ions or Mg ions) is removed. Therefore, even when hard water containing a large amount of hardness components is used, it is possible to suppress precipitation of CaCO 3 scale in an alkaline state.

[0140] In this way, the hardness component removal part 27 having the cation exchange resin regenerated to be of an Na-type allows the configuration to be simple and the hardness component (for example, Ca ions or Mg ions) contained in water such as tap water to be removed.

[0141] (Technique 12) In the above Technique 10 or Technique 11, the flow path 23 may include a bypass flow path 233 that branches from the main flow path 231 downstream of the hardness component removal part 27, bypasses the liquid generation part 25, and joins the main flow path 231 downstream of the liquid generation part 25.

[0142] In this way, the acidic water or the alkaline water generated by passing through the liquid generation part 25 and the liquid passing through the bypass flow path 233 can be mixed to dilute the acidic water or the alkaline water. Therefore, even when acidic water or alkaline water is generated using high-hardness water, it is possible to generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H).

[0143] In this way, when the flow path 23 includes the bypass flow path 233, even if water such as tap water is high-hardness water having a very large amount of hardness components, it is possible to generate acidic water or alkaline water having a pH in a desired range (pH appropriate for treatment of the hair H). As a result, even when high-hardness water is used, it is possible to prevent an excessive load due to an acid or an alkali from being applied to the hair H, and it is possible to suppress thermal damage that hair receives as much as possible during treatment using the hair iron 1.

[0144] (Technique 13) In any one of Techniques 3 to 12, the discharge port 21 may include a first discharge port 211 through which the acidic water is configured to be discharged to the outside of the main body part 10 and a second discharge port 212 through which the alkaline water is configured to be discharged to the outside of the main body part 10. The flow path 23 may include a first flow path 234 connected to the first discharge port 211 and a second flow path 235 connected to the second discharge port 212.

[0145] This makes it possible to neutralize the acidic water and the alkaline water remaining on the hair H after the hair H is treated with the acidic water or the alkaline water. Therefore, it is possible to prevent the hair H from remaining in the acidic state or the alkaline state unlike in the case where the hair H is treated with only one of the acidic water and the alkaline water.

[0146] Therefore, when the hair H is treated with the acidic water and the alkaline water, it is possible to apply, to the hair H, a so-called rinsing effect in which the acidic water and the alkaline water remaining on the hair H are neutralized after the hair H is treated, and the state of the hair H is set to a normal state (weakly acidic state which is the isoelectric point of healthy hair H).

[0147] (Technique 14) In the above Technique 13, the liquid generation part 25 may include an electrolytic liquid generation part 252 that generates an electrolytic liquid by electrolyzing the supplied liquid. The flow path 23 may include the introduction path 236 communicating with the electrolytic liquid generation part 252 upstream of the electrolytic liquid generation part 252, the first flow path 234 communicating with a part (an acidic water discharge path 2521) of the electrolytic liquid generation part 252 where the acidic water is generated, and the second flow path 235 communicating with a part (an alkaline water discharge path 2522) of the electrolytic liquid generation part 252 where the alkaline water is generated.

[0148] This makes it possible to reduce the number of components of the liquid discharge part 20 configured to apply the rinsing effect to the hair H. This makes it possible to simplify the configuration of the liquid discharge part 20 configured to apply the rinsing effect to the hair H.[Others]

[0149] Although the contents of the hair iron according to the present disclosure have been described above, the present disclosure is not limited to these descriptions, and it would be obvious to those skilled in the art that various modifications and improvements can be made.

[0150] For example, the present disclosure can be applied to an embodiment in which a change, replacement, addition, or omission is made to the configuration illustrated in the above-described embodiment and the modification examples thereof. Further, it is also possible to provide a new embodiment by combining the components described in the above embodiment and the modifications thereof.

[0151] When the liquid generation part 25 generates the acidic water and the alkaline water and discharges the generated acidic water or alkaline water from the discharge port (generated water discharge part) 21 toward the hair H, the acidic water or the alkaline water may be controlled to be selected and discharged at an appropriate timing according to the state of the hair H.

[0152] In this way, for example, a treatment performed by releasing acidic water having an excessively low pH or alkaline water having an excessively high pH to the hair H can be performed while appropriately diluting such water with the alkaline water or the acidic water. That is, when the treatment is performed by releasing acidic water having an excessively low pH to the hair H, the acidic water may be appropriately diluted with the alkaline water, and when the treatment is performed by releasing alkaline water having an excessively high pH to the hair H, the alkaline water may be appropriately diluted with the acidic water. In this way, it is possible to suppress the application of an excessive load due to acid or alkali to the hair H, and to improve the treatment effect on the hair H having a strong unruliness.

[0153] In addition, it is also possible to adopt a configuration in which the supply state of the alkali or the acid supplied to the hair H is detected by a sensor and the like, and when the alkali or the acid is excessively supplied, the alkali or the acid is appropriately diluted with an acidic or alkali liquid (acidic water when the alkali is excessively supplied, and alkaline water when the acid is excessively supplied).

[0154] The present disclosure can also be applied to various forms of hair irons.

[0155] For example, the present disclosure can be applied to the hair iron 1 as shown in FIGS. 13 and 14. FIG. 13 is a diagram illustrating another example of the hair iron 1 according to the embodiment, and is a diagram schematically illustrating a state where the hair iron 1 is closed. FIG. 14 is a diagram illustrating another example of the hair iron 1 according to the embodiment, and is a diagram schematically illustrating a state where the hair iron 1 is opened.

[0156] In the hair iron 1 shown in FIGS. 13 and 14, a power supply part 15 provided with an operation element such as a switch button 16 for power supply on the side thereof is provided in the vicinity of hinge part 13, that is, close to the gripping part (the first gripping part 112 and the second gripping part 122) of the first arm part 11 and the second arm part 12.

[0157] The power supply part 15 is housed in the housing (the first housing 111 and the second housing 121) in a partially exposed state. When the hair iron 1 is in the closed state, the entire operation element such as the switch button 16 for power supply is covered with the housing (the first housing 111 and the second housing 121) in a side view. On the other hand, when the hair iron 1 is in the open state, an operation element such as the switch button 16 for power supply is exposed from the housing (the first housing 111 and the second housing 121).

[0158] The hair iron 1 is provided with a lock part 17, and by operating the lock part 17, the first arm part 11 and the second arm part 12 can be held in a closed state.

[0159] In this way, the operation element cannot be operated in a state where the first arm part 11 and the second arm part 12 are closed, and the operation element can be operated by releasing the lock by the lock part 17 to open the first arm part 11 and the second arm part 12.

[0160] With such a configuration, for example, when the hair iron 1 is stored, or when the hair iron 1 is stored in a bag and carried, the first arm part 11 and the second arm part 12 can be prevented from being opened. In addition, when the first arm part 11 and the second arm part 12 are in the closed state, the operation element cannot be operated. Therefore, it is possible to prevent the operation element from being erroneously operated in the stored state. That is, it is possible to more reliably prevent the power supply from being unintentionally turned on.

[0161] Such a configuration is particularly effective when the hair iron 1 is a cordless type.

[0162] In the hair iron 1 shown in FIGS. 13 and 14, when the hair iron 1 is in the closed state, the entire operation element such as the switch button 16 for power supply is covered with the housing (the first housing 111 and the second housing 121) in the side view. However, the operation element such as the switch button 16 for power supply may be in a state in which the operation element cannot be operated when the hair iron 1 is in the closed state. For example, a part of the operation element may be exposed from the housing (the first housing 111 and the second housing 121) in the side view.

[0163] It is also possible to adopt a configuration in which the operation can be performed when the hair iron 1 is merely in a closed state, but the operation cannot be performed when the hair iron 1 is locked by the lock part 17.

[0164] Although the hair iron 1 in which the gripping part is divided into the first gripping part 112 and the second gripping part 122 is illustrated in the above embodiment and the modification thereof, a hair iron in which the first hair clamping part 113 and the second hair clamping part 123 are connected to one end of the gripping part that is not divided may be provided.

[0165] In addition, in the above-described embodiment and the modification example thereof, the liquid discharge part 20 including the liquid generation part 25 is exemplified, but a liquid discharge part not including the liquid generation part 25 may be used.

[0166] For example, acidic water or alkaline water generated in advance may be stored in the storage part 22, and the acidic water or alkaline water stored in the storage part 22 may be discharged from the discharge port 21 toward the hair H through the flow path 23 by driving the liquid feeding pump (liquid feeding part) 24.
