DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.

[0011] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] In addition, the following embodiments and their modified examples include similar components, and therefore, in the following, the similar components are given the same reference numerals and redundant explanations are omitted.

[0013] (Embodiment) The hair iron 1 according to this embodiment includes a main body 10 that is elongated in one direction (hereinafter, described as the front-rear direction). As shown in Fig. 1 and Fig. 2, the main body 10 includes a first arm 11 and a second arm 12 that are connected to each other via a hinge 13 so as to be expandable (openable and closable) in a substantially V-shape. The first arm 11 and the second arm 12 are rotated relative to each other via the hinge 13, so that the tips of the first arm 11 and the second arm 12 can be moved toward and away from each other.

[0014] That is, in this embodiment, as the first arm portion 11 and the second arm portion 12 rotate relative to each other, the first hair clamping surface (hair clamping surface: hair holding surface) 1131 and the second hair clamping surface (hair clamping surface: hair holding surface) 1231 described below can be moved closer to or farther away from each other.

[0015] A first gripping portion (grip) 112 and a second gripping portion (grip) 122 are provided on the hinge portion 13 side (rear side of the hair iron 1) of the first arm portion 11 and the second arm portion 12, respectively. A first hair clamping portion 113 and a second hair clamping portion 123 are provided on the tip side (front side of the hair iron 1) of the first arm portion 11 and the second arm portion 12, respectively.

[0016] The first hair clamping portion 113 and the second hair clamping portion 123 have a first hair clamping surface 1131 and a second hair clamping surface 1231 that can approach or move away from each other (can be made to face each other) when the first arm portion 11 and the second arm portion 12 are rotated relative to each other. Specifically, when the first arm portion 11 and the second arm portion 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 be able to clamp the hair H of the user U. The first hair clamping surface 1131 and the second hair clamping surface 1231 can be formed, for example, using an aluminum plate. In this case, the surface of the aluminum plate is subjected to an anodizing treatment or a glass coating treatment. When alkaline water is used, it is desirable to apply a ceramic coating treatment, which has a higher chemical resistance than glass, to the surface of the aluminum plate.

[0017] In addition, in this embodiment, the first hair clamping surface 1131 and the second hair clamping surface 1231 are formed into a roughly rectangular shape that is elongated in the front-to-back direction when viewed along the direction in which they face each other (the normal direction of the first hair clamping surface 1131 and the second hair clamping surface 1231) when the first arm portion 11 and the second arm portion 12 are closed.

[0018] It is preferable that the first hair clamping surface 1131 and the second hair clamping surface 1231 are configured to be able to float using a float mechanism such as a coil spring, or to be able to be deformed flexibly, thereby preventing excessive load 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 that allows for flexural deformation can be formed, for example, by arranging multiple elongated plates in the width direction intersecting with the front-rear direction so that each plate can be independently floated in the up-down direction.

[0019] Furthermore, in this embodiment, first heater 114 and second heater 124 as heating units are provided on the back side (the side opposite to first hair clamping surface 1131 and second hair clamping surface 1231) of first hair clamping portion 113 and second hair clamping portion 123, as shown in Fig. 4. It is not necessary to heat both first hair clamping portion 113 and second hair clamping portion 123 with a heater, and it is also possible to configure only one of them to be heated.

[0020] Thus, in this embodiment, the hair iron 1 has a main body 10, which has a heating section (first heater 114 and second heater 124) and a hair clamping section (first hair clamping section 113 and second hair clamping section 123) capable of clamping hair H when heated by the heating section.

[0021] The first arm portion 11 and the second arm portion 12 are provided with a first housing 111 and a second housing 121 that form the outer contours of the first arm portion 11 and the second arm portion 12, respectively.

[0022] In addition, a power cord (not shown) is attached to the rear end 10a of the main body 10 of the hair iron 1, and this power cord is electrically connected to a control device 30 that controls the heaters (first heater 114 and second heater 124) via lead wires (wiring) 40.

[0023] Furthermore, the first arm portion 11 of the hair iron 1 is provided with an operation switch 14, and by operating this operation switch 14, it is possible to switch on and off the power supply to the heaters (first heater 114 and second heater 124). The heaters (first heater 114 and second heater 124) and sensors, which will be described later, are desirably sealed with a ceramic material such as alumina, which is resistant to alkali corrosion.

[0024] It is also possible to make the hair iron into a cordless type by incorporating a battery (rechargeable battery) or storing replaceable (non-rechargeable) dry batteries inside the main body 10.

[0025] 3, when using such a hair iron 1, a user U grips the gripping parts (first gripping part 112 and second gripping part 122) and clamps the hair H between the first hair clamping surface 1131 and the second hair clamping surface 1231. With the hair H clamped 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 via the first hair clamping surface 1131 and the second hair clamping surface 1231, thereby performing a treatment on the hair H (for example, forming the hair H into a curled or straight shape).

[0026] In addition, hair H can be straightened, for example, by holding the root side of the hair H between the first hair clamping surface 1131 and the second hair clamping surface 1231 and sliding the hair iron 1 along the hair H and pulling it down toward the ends.

[0027] In this manner, the hair iron 1 according to the present embodiment has a gripping portion (first gripping portion 112 and second gripping portion 122) having a hair gripping surface (first hair clamping surface 1131 and second hair clamping surface 1231) for gripping the hair H, and a heating portion (first heater 114 and second heater 124) for heating the hair H gripped by the gripping portion (first gripping portion 112 and second gripping portion 122) on the hair gripping surface (first hair clamping surface 1131 and second hair clamping surface 1231). The hair iron 1 according to the present embodiment is thus configured to set the hair H by heat, and performs hair styling (treatment of the hair H) by setting the hair H by heat.

[0028] Here, in this embodiment, it is possible to further improve the treatment effect on the hair H while minimizing heat damage that the hair H receives during the treatment.

[0029] Specifically, as shown in Fig. 4, the hair iron 1 includes a liquid discharge section (produced water discharge section) 20 provided on the main body section 10. The liquid discharge section 20 has a discharge port (produced water discharge section) 21 capable of discharging acidic water or alkaline water to the outside of the main body section 10.

[0030] Furthermore, in this embodiment, the liquid discharge section 20 is provided with a storage section (liquid supply tank) 22 capable of storing liquid, a flow path 23 connecting the storage section 22 with the discharge port 21, and a liquid delivery pump (liquid delivery section) 24 provided in the flow path 23 and capable of delivering the liquid in the storage section 22 to the discharge port 21 side.

[0031] In the storage section 22, raw water such as tap water or well water can be stored. As a method of supplying liquid to the storage section 22, for example, a container constituting the storage section 22 is removably held in the main body section 10, the container is removed from the main body section 10, liquid is stored in the container, and the container is then attached to the main body section 10. There is also a method of supplying liquid to the storage section 22 by providing an opening that is closed by a lid member so as to be openable and closable in the main body section 10 so as to communicate with the storage section 22, and injecting liquid from the opening that is opened by removing the lid member.

[0032] The liquid such as raw water stored in the storage section 22 is supplied to the discharge port 21 through the flow path 23. In this manner, in the present embodiment, the flow path 23 from the storage section 22 to the discharge port 21 serves as the main flow path 231 of the liquid discharge section 20. That is, the flow path 23 includes one main flow path 231 that runs from the storage section 22 to the discharge port 21.

[0033] A liquid delivery pump (liquid delivery section) 24 is connected downstream of the storage section 22 of the flow path 23, and by driving this liquid delivery pump (liquid delivery section) 24, liquid such as raw water stored in the storage section 22 is delivered to the downstream side of the flow path 23. This liquid delivery pump (liquid delivery section) 24 is electrically connected to the control device 30 via wiring (not shown), and the supply of power and operation (drive) are controlled by this control device 30.

[0034] Furthermore, in this embodiment, a liquid generating section 25 is disposed downstream of the liquid sending pump (liquid sending section) 24 of the flow path 23, and by driving the liquid sending pump (liquid sending section) 24, liquid such as raw water stored in the storage section 22 is supplied to the liquid generating section 25. The liquid generating section 25 generates at least one of acidic water and alkaline water, and the acidic water or alkaline water generated in the liquid generating section 25 is sent (sent) to the outlet 21 by the liquid sending pump (liquid sending section) 24 and is discharged from the outlet 21 toward the hair H. At this time, it is preferable that the acidic water or alkaline water is discharged from the outlet 21 in the form of a mist. Such a form can be obtained, for example, by making the outlet 21 an outlet of a spray nozzle or by generating ultrasonic atomization using an ultrasonic element. The discharge of the liquid (acidic water or alkaline water) from the outlet 21 to the hair H can be performed by a continuous operation or an intermittent operation. Such continuous or intermittent operation can be controlled by, for example, the control device 30.

[0035] Furthermore, in this embodiment, an ion exchange unit 251 capable of performing ion exchange with the liquid passing through the inside is used as the liquid generating unit 25. That is, a liquid releasing unit 20 in which the liquid generating unit 25 includes the ion exchange unit 251 is exemplified.

[0036] This ion exchange section 251 can be provided with a cation exchange section 2511 having a cation exchange resin regenerated to H type, or it can be provided with an anion exchange section 2512 having an anion exchange resin regenerated to OH type.

[0037] For example, if the ion exchange unit 251 is provided with a cation exchange unit 2511 having a cation exchange resin regenerated to H type, when a liquid such as raw water is passed through the cation exchange unit 2511, the cations contained in the liquid such as raw water are exchanged with the H ions in the ion exchange resin to produce acidic water.

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

[0039] Thus, in this embodiment, the liquid generating unit 25 includes an ion exchange unit 251 incorporating an ion exchange resin that generates acidic water or alkaline water. Note that the ion exchange unit 251 may have a member capable of ion exchange, such as an ion exchange fiber or an ion exchange filter carrying an ion exchange resin. That is, the ion exchange unit 251 can be formed using at least one type of member capable of ion exchange among ion exchange resin, ion exchange fiber, ion exchange filter carrying an ion exchange resin, and the like.

[0040] In this embodiment, a replenisher liquid obtained by supplementing tap water or the like with saline solution as an electrolyte whose concentration has been adjusted in advance is stored as raw water in storage unit 22. Note that raw water may be supplied to storage unit 22 in which tablet-shaped salt is placed, thereby generating a replenisher liquid supplemented with saline solution in storage unit 22. In this manner, a liquid to which salt has been added as an electrolyte, i.e., a liquid in which the amount of dissolved ions has been increased, is supplied to liquid generating unit 25.

[0041] In this manner, in this embodiment, the amount of ion exchange can be adjusted by the electrolyte (salt).

[0042] In this way, even if water such as tap water is soft water with a low hardness content, it is possible to generate acidic water or alkaline water with a desired pH range (a pH appropriate for treating the hair H). In other words, even if tap water from a soft water area is used, it is possible to supply the necessary amount of acid or alkaline liquid to the hair H when treating the hair H with the hair iron 1.

[0043] When treating hair H using a hair iron 1 configured in this manner, acidic water or alkaline water is generated and sprayed onto the hair H, and the hair H is straightened using the heated hair clamping surfaces (first hair clamping surface 1131 and second hair clamping surface 1231), among other operations, to thermally shape the hair H.

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

[0045] At this time, when the ion exchange unit 251 is provided with a cation exchange unit 2511 having a cation exchange resin regenerated to H type, the internal cation exchange resin is replaced to H type and is strongly acidic, so that the NaCl in the aqueous solution is dissolved in the cation exchange resin. + and H bound to the cation exchange resin + As a result of ion exchange, the pH of the liquid decreases and acidic water is produced.

[0046] Then, the acidic water generated in the ion exchange unit 251 is sprayed from the outlet 21 toward the hair H. At this time, it is preferable that the acidic water is sprayed toward the tip side of the hair H clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231. In this way, when the hair iron 1 is pulled down toward the tip, the acidic water is attached to the 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 and treated, the ionic bond of the hair H is broken by the acidic water, so that the treatment effect of the hair H can be further improved even if the hair H is strongly curled.

[0047] On the other hand, when the ion exchange unit 251 is provided with the anion exchange unit 2512 having an anion exchange resin regenerated to the OH type, the internal anion exchange resin is strongly basic due to substitution to the OH type, and therefore the Cl of the NaCl aqueous solution is - and OH bound to anion exchange resin - As a result of ion exchange, the pH of the liquid increases and alkaline water is produced.

[0048] Then, the alkaline water generated in the ion exchange unit 251 is sprayed from the outlet 21 towards the hair H. In this way, the hair H whose 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, so that the treatment effect on the hair H can be improved even for hair H that is strongly curled.

[0049] In this manner, in the present embodiment, when treating hair H using hair iron 1, acidic water or alkaline water is released toward hair H from outlet 21, so that hair H can be treated with acidic water or alkaline water adhered to hair H.

[0050] By applying acidic water or alkaline water to the hair H, the ionic bonds of the amino acids in the hair H are broken by the acidic water or alkaline water. When the ionic bonds of the amino acids in the hair H are broken in this manner, the cuticle of the hair H opens, making it possible to make the hair H in a state in which it is easy to straighten its curls. In other words, it becomes possible to make the hair H in a state in which it is easy to work it into a desired shape.

[0051] The hair H in this state can then be clamped and treated with the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) heated by the heating part. This makes it possible to more reliably shape the hair H into the desired shape, even if the hair H is strongly curled.

[0052] Then, by clamping the hair H in this state with the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) heated by the heating unit and treating it, it is possible to more reliably shape the hair H into the desired shape, even if the hair H is very curly.

[0053] In this way, 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 this embodiment, it becomes possible to treat the hair H in a state where the ionic bonds have been broken in advance using acidic water or alkaline water. Therefore, even if the temperature of the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) is set to a lower temperature than usual, it becomes possible to further improve the treatment effect on the hair H. In this way, it becomes possible to treat the hair H in a state where thermal damage is small.

[0055] In this way, the hair iron 1 according to the present embodiment can improve the treatment effect on the hair H while minimizing heat damage to the hair H caused by the treatment.

[0056] At this time, if alkaline water is applied to the hair H, the cuticle layer can be swelled by the alkali, which allows the alkali to penetrate further into the hair H. As a result, the ionic bonds of the amino acids are broken even inside the hair H, making it possible to further improve the treatment effect even for hair with strong curls.

[0057] In addition, if acidic water is applied to the hair H, the cations contained in the liquid such as raw water are ion-exchanged with the H ions in the ion exchange resin when the acidic water is generated, so that it becomes possible to remove the Ca ions contained in the liquid such as raw water. As a result, the adhesion of Ca to damaged parts of the hair H is suppressed, and the stiffness of the hair H can be further reduced.

[0058] Furthermore, in this embodiment, the storage section 22 is configured to store liquid, so that even when the hair iron 1 is used alone, acidic water or alkaline water can be applied to the hair H when the hair H is treated. In this way, even when the hair iron 1 alone with liquid stored in the storage section 22 is carried to a travel destination and used, acidic water or alkaline water can be applied to the hair H when the hair H is treated, and the usability of the hair iron 1 can be further improved.

[0059] In addition, in this embodiment, an electrolyte (salt) that does not contain Ca is used to increase the amount of ions dissolved in the raw water. This makes it possible to generate acidic water or alkaline water using a liquid with a small amount of dissolved Ca ions. This makes it possible to suppress the precipitation of CaCO3 scale in an alkaline state when an OH-type ion exchange resin is used.

[0060] In addition, when H-type ion exchange resin is used, Ca ions are removed (ion-exchanged with H ions) when acidic water is generated, making it possible to supply a liquid (acidic water) with less Ca to the hair H.

[0061] In this embodiment, as an example of a method for increasing the amount of ions dissolved in the raw water, a replenishment solution in which tap water or the like is supplemented with saline solution having a pre-adjusted concentration as an electrolyte is stored in storage section 22; however, it is possible to increase the amount of ions dissolved in the raw water in various ways.

[0062] For example, the liquid discharge section 20 can be provided with an electrolyte storage section (electrolyte addition section) 26 that is disposed upstream of the liquid generation section 25 and that can add an electrolyte (salt) to the liquid. Specifically, as shown in Fig. 5, the electrolyte storage section (electrolyte addition section) 26 in which the electrolyte (salt) is stored can be disposed between the liquid delivery pump (liquid delivery section) 24 and the liquid generation section 25, and the liquid to which the electrolyte (salt) has been added can be supplied to the liquid generation section 25 through the electrolyte storage section (electrolyte addition section) 26.

[0063] 6, an inlet path 232 communicating with the electrolyte storage section (electrolyte adding section) 26 is connected to the flow path 23 between the liquid sending pump (liquid sending section) 24 and the liquid generating section 25, and the electrolyte (salt) stored in the electrolyte storage section (electrolyte adding section) 26 is introduced into the flow path 23 via the inlet path 232, so that the liquid to which the electrolyte (salt) has been added can be supplied to the liquid generating section 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 a continuous operation or intermittent operation can be controlled by, for example, the control device 30.

[0064] In addition, when the generated acidic water or alkaline water is released from the outlet (generated water release section) 21 toward the hair H, it is also possible to configure the water to be selected and released at an appropriate timing depending on the condition of the hair H.

[0065] The electrolyte to be added to the liquid is not limited to salt, and various electrolytes can be added to the liquid. For example, various electrolytes (neutral salt electrolytes) such as potassium chloride, sodium carbonate, sodium sulfate, and copper chloride can be added to the liquid. In this case, one type of electrolyte may be added to the liquid, or multiple types of electrolytes may be added to the liquid.

[0066] Also, as shown in FIG. 7, the liquid release section 20 can be provided with a water quality determination section 28 that determines the hardness of the liquid introduced into the liquid generation section 25, and an electrolyte storage section (electrolyte addition section) 26 that is positioned upstream of the liquid generation section 25 and is capable of adding electrolytes to the liquid.

[0067] For example, a hardness sensor that measures the hardness of the liquid can be used as this water quality determination unit 28. It is also possible for the water quality determination unit 28 to include a hardness sensor and a hardness determination unit that determines whether the liquid introduced into the liquid generating unit 25 is soft water or hard water based on the hardness measured by the hardness sensor.

[0068] It is also possible to configure the system so that an appropriate method of adding electrolytes is controlled based on the result of the liquid hardness determination by the water quality determination unit 28. Such control can also be performed by the control device 30. For example, if the water quality determination unit 28 includes a hardness sensor and a hardness determination unit, it can control the addition of electrolytes in an appropriate manner based on the determination by the hardness determination unit (determination of whether the water is soft water or hard water). Such a hardness determination unit can be provided in the control device 30.

[0069] This makes it possible to introduce liquid of a more appropriate hardness into the liquid generating section 25, thereby making it possible to more reliably generate acidic water or alkaline water with a desired pH range (a pH appropriate for treating hair H).

[0070] As a method for controlling the supply of an appropriate electrolyte by the control device 30, there is a method for adjusting the amount of electrolyte to be added based on the result of the liquid hardness determination by the water quality determination unit .

[0071] There is also a method of adjusting the type of electrolyte to be added based on the result of the liquid hardness judgment by the water quality judgment unit 28. In this case, it is possible to select and add one type of electrolyte, or to select and add multiple types of electrolytes by mixing them in an appropriate ratio.

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

[0073] It is also possible to configure the system so that the method of applying the electrolyte is controlled appropriately based on the detection result of the hair condition detection unit (the condition of the hair H). This type of control can also be controlled by the control device 30.

[0074] As a method of controlling the appropriate application of electrolyte by the control device 30, there is a method of adjusting the amount of electrolyte to be added based on the detection result (the condition of the hair H) of the hair condition detection unit.

[0075] There is also a method of adjusting the type of electrolyte to be added based on the detection result of the hair condition detection unit (the condition of the hair H). In this case, it is possible to select and add one type of electrolyte, or to select and add multiple types of electrolytes by mixing them in an appropriate ratio.

[0076] This also makes it possible to introduce liquid of a more appropriate hardness into the liquid generating section 25, making it possible to more reliably generate acidic water or alkaline water with a desired pH range (a pH appropriate for treating hair H).

[0077] In addition, the hair iron 1 can be provided with a hair condition detection unit and an acidity / alkalinity control unit that controls the acidity of the generated acidic water and the alkalinity of the generated alkaline water based on the detection results of the hair condition detection unit (the condition of the hair H), so that acidic water with a more appropriate acidity or alkaline water with a more appropriate alkalinity is released onto the hair H.

[0078] It is also possible to use liquids that do not require the addition of electrolyte.

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

[0080] However, when alkaline water is generated using hard water that contains a lot of hardness components such as Ca and Mg, CaCO3 scale may be precipitated or Ca may adhere to damaged areas of the hair H.

[0081] Therefore, when using hard water containing a large amount of hardness components such as Ca and Mg, it is preferable to provide a hardness component removal section 27 capable of removing the hardness components from the liquid upstream of the liquid generation section 25 of the flow path 23, as shown in Figure 8.

[0082] The hardness component removing section 27 can be formed by using a cation exchange resin regenerated to the Na type. That is, the hardness component removing section 27 can have a cation exchange resin regenerated to the Na type.

[0083] In this way, when liquid (hard water) such as tap water is passed through the hardness component removal section 27, the hardness components (Ca ions and Mg ions) contained in the liquid such as tap water are ion-exchanged with the Na ions in the ion exchange resin, and the hardness components (Ca ions and Mg ions) are removed. Therefore, even if hard water containing a large amount of hardness components is used, it is possible to prevent CaCO3 scale from being precipitated in an alkaline state and Ca from adhering to damaged parts of the hair H.

[0084] In this way, by using the hardness component removal section 27 having a cation exchange resin regenerated into the Na type, it is possible to remove hardness components (Ca ions and Mg ions) contained in water such as tap water while simplifying the configuration.

[0085] However, if the liquid, such as tap water, is high-hardness water with a very high content of hardness components, acidic water with too low a pH or alkaline water with too high a pH will be produced.

[0086] Therefore, when using high-hardness water containing a very large amount of hardness components, it is preferable that the flow path 23 is provided with a bypass flow path 233 that branches off from the main flow path 231 downstream of the hardness component removal section 27, bypasses the liquid production section 25, and joins the main flow path 231 downstream of the liquid production section 25, as shown in Figure 9.

[0087] In this way, it is possible to dilute the acidic water or alkaline water by mixing the acidic water or alkaline water generated by passing through the liquid generating unit 25 with the liquid that has passed through the bypass flow path 233. Therefore, even if the acidic water or alkaline water is generated using high hardness water, it is possible to generate acidic water or alkaline water having a desired pH range (a pH appropriate for treating the hair H).

[0088] In this way, by providing the flow path 23 with the bypass flow path 233, even if the liquid such as tap water is high-hardness water with a very large amount of hardness components, it is possible to generate acidic water or alkaline water with a desired pH range (a pH appropriate for treating the hair H). As a result, even when high-hardness water is used, it is possible to prevent the hair H from being subjected to more than necessary stress due to acid or alkali, and it is possible to minimize heat damage to the hair H when treating the hair with the hair iron 1.

[0089] It is also possible for the hair iron 1 to emit both acidic water and alkaline water onto the hair H when treating the hair H.

[0090] For example, as shown in Fig. 10, the outlet 21 may include a first outlet 211 capable of releasing acidic water to the outside of the main body 10, and a second outlet 212 capable of releasing alkaline water to the outside of the main body 10. It is preferable that the first outlet 211 and the second outlet 212 are formed as far apart as possible on the main body 10, so that the acidic water and alkaline water sprayed from the respective outlets are prevented from mixing and being neutralized before being attached to the hair. Fig. 10 shows an example in which the first outlet 211 is provided on the tip side of the first hair clamping part 113, and the second outlet 212 is provided on the second gripping part 122 side 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] This makes it possible to neutralize the acidic water and alkaline water remaining in the hair H after the hair H has been treated with acidic water or alkaline water. This makes it possible to prevent the hair H from remaining in an acidic or alkaline state, as occurs when the hair H is treated with only acidic water or alkaline water.

[0093] Therefore, as shown in FIG. 10, if the hair H is treated using acidic water and alkaline water, the acidic water and alkaline water remaining in the hair H can be neutralized after the hair H is treated, thereby providing the hair H with a so-called rinsing effect, which returns the hair H to its normal state (a weakly acidic state which is the isoelectric point of healthy hair H).

[0094] In addition, in FIG. 10, an example is shown in which the first flow path 234 and the second flow path 235 are independent flow paths and acidic water and alkaline water are generated separately. However, as shown in FIG. 11, it is also possible to configure the flow path 23 to branch midway and to place an electrolyte liquid generating unit 252 capable of generating both acidic water and alkaline water at the branched portion.

[0095] That is, the liquid generating unit 25 can be provided with an electrolytic liquid generating unit 252 that electrolyzes a supplied liquid to generate an electrolytic liquid. The flow path 23 can be provided with an inlet path 236 that communicates with the electrolytic liquid generating unit 252 on the upstream side of the electrolytic liquid generating unit 252, a first flow path 234 that communicates with the side of the electrolytic liquid generating unit 252 where acidic water is generated (acidic water discharge path 2521), and a second flow path 235 that communicates with the side of the electrolytic liquid generating unit 252 where alkaline water is generated (alkaline water discharge path 2522).

[0096] This makes it possible to reduce the number of components of the liquid release section 20 capable of imparting a rinsing effect to the hair H, thereby making it possible to simplify the configuration of the liquid release section 20 capable of imparting a rinsing effect to the hair H.

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

[0098] For example, a liquid discharge section 20 as shown in FIG. 12 may be used.

[0099] FIG. 12 shows an example in which any one of the routes shown in FIG. 4, the route shown in FIG. 8, and the route shown in FIG. 9 can be selected.

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

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

[0102] Furthermore, an on-off valve 29 formed of a solenoid valve or the like is also provided at the junction located upstream of the discharge port 21. This on-off valve 29 is also electrically connected to the control device 30 via wiring 40, and is controlled by the control device 30 so that only one of the paths is open. This prevents the water from flowing into the other path.

[0103] The control device 30 controls the opening and closing of each on-off valve 29, so that any one of the paths shown in Fig. 4, Fig. 8, and Fig. 9 can be selected. This path selection can be performed, for example, by operating a mode selection switch provided in the main body 10. It is also possible to provide a sensor in the storage unit 22, and have the control device 30 select the optimal path based on the measurement results of hardness and pH by the sensor.

[0104] In FIG. 12, the liquid delivery pump (liquid delivery section) 24 is also electrically connected to the control device 30 via a wire 40, and the drive of the liquid delivery pump (liquid delivery section) 24 is controlled by this control device 30.

[0105] [Actions and Effects] The following describes the characteristic configurations of the hair irons shown in the above-described embodiments and their modified examples, and the effects obtained thereby.

[0106] (Technology 1) The hair iron 1 shown in the above embodiment and its modified example includes a main body 10. The main body 10 includes a heating unit (first heater 114 and second heater 124) and a hair clamping unit (first hair clamping unit 113 and second hair clamping unit 123) capable of clamping hair H when heated by the heating unit.

[0107] Furthermore, the hair iron 1 has a discharge port 21 capable of discharging the acidic water or alkaline water to the outside of the main body 10, and is equipped with a liquid discharge part 20 provided in the main body 10.

[0108] When such a hair iron 1 is used to treat the hair H, the hair H can be treated while the hair H is in a state where acidic water or alkaline water is applied to the hair H.

[0109] In this way, by applying acidic water or alkaline water to the hair H, the ionic bonds of the amino acids in the hair H are broken by the acidic water or alkaline water, and the cuticle of the hair H is opened, so that the hair H can be made to be in a state in which it is easy to straighten its curls. In other words, the hair H can be made to be in a state in which it is easy to work it into a desired shape.

[0110] Then, by clamping the hair H in this state with the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) heated by the heating unit and treating it, it is possible to more reliably shape the hair H into the desired shape, even if the hair H is very curly.

[0111] In this way, by using the hair iron 1 shown in the above embodiment and its modified example, it is possible to improve the treatment effect on the hair H.

[0112] Furthermore, by using the hair iron 1 shown in the above embodiment and its modified example, it becomes possible to treat the hair H in a state where the ionic bonds have been broken in advance with acidic water or alkaline water. Therefore, even if the temperature of the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) is set to a lower temperature than usual, it becomes possible to further improve the treatment effect on the hair H. In this way, it becomes possible to treat the hair H in a state where heat damage is small.

[0113] In this way, the hair iron 1 shown in the above embodiment and its modified examples makes it possible to improve the treatment effect on the hair H while minimizing heat damage to the hair H during treatment.

[0114] (Technology 2) In the above (Technology 1), the liquid discharge section 20 may include a storage section 22 capable of storing liquid, and a flow path 23 that connects the storage section 22 to the discharge port 21. Furthermore, the liquid discharge section 20 may include a liquid delivery pump (liquid delivery section) 24 that is provided in the flow path 23 and is capable of delivering the liquid in the storage section 22 to the discharge port 21 side.

[0115] With this configuration, storing liquid in the storage section 22 makes it possible to apply acidic water or alkaline water to the hair H when treating the hair H, even when using only the hair iron 1 alone. In this way, even when the hair iron 1 alone with liquid stored in the storage section 22 is carried to a travel destination and used, it becomes possible to apply acidic water or alkaline water to the hair H when treating the hair H, thereby making it possible to further improve the usability of the hair iron 1.

[0116] (Technology 3) In the above (Technology 2), the liquid discharge section 20 may be provided with a liquid generator 25 that is provided in the flow path 23 and is capable of generating at least one of acid water and alkaline water.

[0117] With this configuration, simply storing tap water or the like in the storage unit 22 makes it possible to apply acidic water or alkaline water to the hair H when the hair H is treated. That is, acidic water or alkaline water is generated in the liquid generating unit 25 using water such as tap water, and the generated acidic water or alkaline water can be applied to the hair H when the hair H is treated using the hair iron 1. In this way, even when the hair iron 1 is carried alone to a destination for use while traveling, for example, it becomes possible to apply acidic water or alkaline water to the hair H when the hair H is treated using water at the destination, thereby further improving the usability of the hair iron 1.

[0118] (Technology 4) In the above (Technology 3), the liquid generating section 25 may include an ion exchange section 251.

[0119] In this way, acidic water or alkaline water can be produced simply by passing water such as tap water through the ion exchange section 251, making it possible to more easily produce acidic water or alkaline water using water such as tap water while simplifying the configuration.

[0120] (Technology 5) In the above (Technology 4), the ion exchange section 251 may include a cation exchange section 2511 having a cation exchange resin regenerated into H-type.

[0121] In this way, when water such as tap water is passed through the cation exchange section 2511, the cations contained in the water such as tap water are exchanged with the H ions in the ion exchange resin to produce acidic water. Therefore, if the ion exchange section 251 is provided with the cation exchange section 2511, acidic water can be produced simply by passing water such as tap water through the cation exchange section 2511, and acidic water can be produced more easily using water such as tap water while simplifying the configuration.

[0122] In addition, if the cations contained in water such as tap water are ion-exchanged with the H ions in the ion exchange resin, it becomes possible to remove the Ca ions contained in water such as tap water. As a result, the adhesion of Ca to damaged parts of the hair H is suppressed, and the stiffness of the hair H can be further reduced.

[0123] Furthermore, if the ion exchange section 251 is provided with a cation exchange section 2511, it becomes possible to further improve the treatment effect even on hair with stronger curls.

[0124] (Technology 6) In the above (Technology 4) or (Technology 5), the ion exchange section 251 may include an anion exchange section 2512 having an anion exchange resin regenerated into OH type.

[0125] In this way, when water such as tap water is passed through anion exchange section 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, if ion exchange section 251 is provided with anion exchange section 2512, alkaline water can be generated simply by passing water such as tap water through anion exchange section 2512, and alkaline water can be generated more easily using water such as tap water while simplifying the configuration.

[0126] Furthermore, if alkaline water is applied to the hair H, the cuticle layer can be swelled by the alkali, which allows the alkali to penetrate further into the hair H. As a result, the ionic bonds of the amino acids are broken even inside the hair H, making it possible to further improve the treatment effect even for hair with strong curls.

[0127] (Technology 7) In any of the above (Technology 3) to (Technology 6), the liquid to which an electrolyte has been added may be supplied to the liquid generating unit 25.

[0128] In this way, the amount of ion exchange can be adjusted using electrolytes, so that even if water such as tap water is soft water with a low hardness content, it is possible to produce acidic water or alkaline water with a desired pH range (a pH appropriate for treating hair H).

[0129] In this way, by supplying liquid with added electrolytes to the liquid generating unit 25 to generate acidic water or alkaline water, it becomes possible to supply the necessary amount of acid or alkaline liquid to the hair H when treating the hair H with the hair iron 1, even when using tap water in a soft water area.

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

[0131] In this way, since the electrolyte does not contain Ca, it is possible to generate acidic water or alkaline water using a liquid with a small amount of Ca ions. Therefore, when using an OH type ion exchange resin, it is possible to suppress the precipitation of CaCO3 scale in an alkaline state.

[0132] In addition, when H-type ion exchange resin is used, Ca ions are removed (ion-exchanged with H ions) when acidic water is generated, making it possible to supply a liquid (acidic water) with less Ca to the hair H.

[0133] Furthermore, if salt is used as the electrolyte, it becomes possible to improve the treatment effect even on hair with stronger curls.

[0134] (Technology 9) In the above (Technology 7) or (Technology 8), the liquid releasing section 20 may include a water quality determining section 28 that determines the hardness of the liquid introduced into the liquid generating section 25, and an electrolyte storage section (electrolyte adding section) 26 that is arranged upstream of the liquid generating section 25 and can add electrolyte to the liquid. The hair iron 1 may adjust the amount of electrolyte to be added based on the result of the liquid hardness determination by the water quality determining section 28.

[0135] This makes it possible to introduce liquid of a more appropriate hardness into the liquid generating section 25, thereby making it possible to more reliably generate acidic water or alkaline water with a desired pH range (a pH appropriate for treating hair H).

[0136] (Technology 10) In addition, in any of the above (Technology 3) to (Technology 9), a hardness component removal section 27 capable of removing hardness components from the liquid may be provided upstream of the liquid generating section 25 of the flow path 23.

[0137] In this way, it becomes possible to supply liquid from which ions such as Ca and Mg have been removed to the liquid generating section 25, so that even when hard water containing a large amount of hardness components is used, it becomes possible to suppress the precipitation of CaCO3 scale in an alkaline state.

[0138] (Technology 11) In the above (Technology 10), the hardness component removing section 27 may have a cation exchange resin regenerated into a Na type.

[0139] In this way, when water such as tap water is passed through the hardness component removal section 27, the hardness components (Ca ions and Mg ions) contained in the water such as tap water are ion-exchanged with the Na ions in the ion exchange resin, and the hardness components (Ca ions and Mg ions) are removed. Therefore, even when hard water containing a large amount of hardness components is used, it is possible to suppress the precipitation of CaCO3 scale in an alkaline state.

[0140] In this way, by using the hardness component removal section 27 having a cation exchange resin regenerated into the Na type, it is possible to remove hardness components (Ca ions and Mg ions) contained in water such as tap water while simplifying the configuration.

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

[0142] In this way, it is possible to dilute the acidic water or alkaline water by mixing the acidic water or alkaline water generated by passing through the liquid generating unit 25 with the liquid that has passed through the bypass flow path 233. Therefore, even if the acidic water or alkaline water is generated using high hardness water, it is possible to generate acidic water or alkaline water having a desired pH range (a pH appropriate for treating the hair H).

[0143] In this way, by providing the flow path 23 with the bypass flow path 233, even if water such as tap water is high-hardness water with a very large amount of hardness components, it is possible to generate acidic water or alkaline water with a desired pH range (a pH appropriate for treating the hair H). As a result, even when high-hardness water is used, it is possible to prevent the hair H from being subjected to more stress than necessary due to acid or alkali, and it is possible to minimize heat damage to the hair H when treating the hair with the hair iron 1.

[0144] (Technology 13) In any of the above (Technology 3) to (Technology 12), the outlet 21 may include a first outlet 211 capable of releasing acidic water to the outside of the main body 10, and a second outlet 212 capable of releasing alkaline water to the outside of the main body 10. The flow path 23 may include a first flow path 234 connected to the first outlet 211, and a second flow path 235 connected to the second outlet 212.

[0145] In this way, after treating the hair H with acidic water or alkaline water, it is possible to neutralize the acidic water and alkaline water remaining in the hair H, thereby preventing the hair H from remaining in an acidic or alkaline state, as occurs when treating the hair H using only acidic water or alkaline water.

[0146] Therefore, if the hair H is treated using acidic water and alkaline water, the acidic water and alkaline water remaining in the hair H can be neutralized after the hair H is treated, thereby providing the hair H with a so-called rinsing effect, returning the hair H to its normal state (a weakly acidic state which is the isoelectric point of healthy hair H).

[0147] (Technology 14) In the above (Technology 13), the liquid generating unit 25 may include an electrolytic liquid generating unit 252 that electrolyzes a supplied liquid to generate an electrolytic liquid. The flow path 23 may include an inlet path 236 that communicates with the electrolytic liquid generating unit 252 on the upstream side of the electrolytic liquid generating unit 252, a first flow path 234 that communicates with the side of the electrolytic liquid generating unit 252 where acidic water is generated (acidic water discharge path 2521), and a second flow path 235 that communicates with the side of the electrolytic liquid generating unit 252 where alkaline water is generated (alkaline water discharge path 2522).

[0148] This makes it possible to reduce the number of components of the liquid release section 20 capable of imparting a rinsing effect to the hair H, thereby making it possible to simplify the configuration of the liquid release section 20 capable of imparting a rinsing effect to the hair H.

[0149] [others] The hair iron according to the present disclosure has been described above, but it will be obvious to those skilled in the art that the present disclosure is not limited to this description and that various modifications and improvements are possible.

[0150] For example, the present disclosure can be applied to the embodiments in which the configurations shown in the above-mentioned embodiments and their modified examples are modified, replaced, added, omitted, etc. Also, it is possible to combine the components described in the above-mentioned embodiments and their modified examples to form new embodiments.

[0151] In addition, when the liquid generating section 25 generates acidic water and alkaline water, and the generated acidic water or alkaline water is released from the outlet (generated water releasing section) 21 toward the hair H, it is possible to configure the control so that each is selected and released at an appropriate timing depending on the condition of the hair H.

[0152] In this way, for example, a treatment in which acidic water with too low a pH or alkaline water with too high a pH is released onto the hair H can be performed while appropriately diluting it with alkaline water or acidic water. That is, when acidic water with too low a pH is released onto the hair H for treatment, it can be controlled so that it is appropriately diluted with alkaline water, and when alkaline water with too high a pH is released onto the hair H for treatment, it can be controlled so that it is appropriately diluted with acidic water. In this way, it is possible to prevent the hair H from being subjected to more stress than necessary due to acid or alkali, while improving the treatment effect on curly hair H.

[0153] It is also possible to configure the system so that the supply state of alkali or acid supplied to the hair H is detected by a sensor or the like, and if an excessive amount is being supplied, the system is controlled so as to appropriately dilute the alkali or acid with the opposite liquid (acidic water if an excessive amount of alkali is being supplied, and alkaline water if an excessive amount of acid is being supplied).

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

[0155] For example, the present disclosure can be applied to a hair iron 1 as shown in FIG. 13 and FIG.

[0156] In the hair iron 1 shown in Figures 13 and 14, a power supply unit 15 having an operator such as a power switch button 16 on the side is provided near the hinge portion 13, i.e., on the gripping portion (first gripping portion 112 and second gripping portion 122) side of the first arm portion 11 and the second arm portion 12.

[0157] This power supply unit 15 is accommodated in a partially exposed state inside the housing (first housing 111 and second housing 121). When the hair iron 1 is in a closed state, the entirety of the controls such as the power switch button 16 are covered by the housing (first housing 111 and second housing 121) in a side view. On the other hand, when the hair iron 1 is in an open state, the controls such as the power switch button 16 are exposed from the housing (first housing 111 and second housing 121).

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

[0159] In this way, the operator cannot be operated while the first arm portion 11 and the second arm portion 12 are in the closed state, but the operator can be operated by releasing the lock by the lock portion 17 and setting them in the open state.

[0160] With this configuration, for example, when the hair iron 1 is stored or when it is stored in a bag or the like and carried, the first arm portion 11 and the second arm portion 12 can be prevented from opening. Also, when the first arm portion 11 and the second arm portion 12 are closed, the operation of the operation element cannot be performed, so that the operation element is prevented from being operated by mistake while the hair iron 1 is stored. In other words, it is possible to more reliably prevent the power from being turned on unintentionally.

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

[0162] 13 and 14 show an example in which, when the hair iron 1 is in the closed state, the entire operation buttons, such as the power switch button 16, are covered by the housing (the first housing 111 and the second housing 121) in a side view. However, it is sufficient that the operation buttons, such as the power switch button 16, cannot be operated when the hair iron 1 is in the closed state, and it is also possible, for example, to have a part of the operation button exposed from the housing (the first housing 111 and the second housing 121) in a side view.

[0163] In addition, it is possible to configure the hair iron 1 so that it can be operated simply by placing it in the closed state, but that it cannot be operated when it is locked by the locking section 17.

[0164] In addition, in the above embodiment and its modified example, a hair iron 1 in which the grip portion is divided into first grip portion 112 and second grip portion 122 is exemplified, but it is also possible to make a hair iron in which first hair clamp portion 113 and second hair clamp portion 123 are connected to one end of an undivided grip portion.

[0165] Furthermore, in the above embodiment and its modified example, the liquid releasing section 20 equipped with the liquid generating section 25 has been exemplified, but it is also possible to configure the liquid releasing section without the liquid generating section 25.

[0166] For example, it is possible to store pre-generated acidic water or alkaline water in storage section 22, and by driving liquid delivery pump (liquid delivery section) 24, the acidic water or alkaline water stored in storage section 22 can be released through flow path 23 and from release port 21 towards hair H.

[0167] It is also possible to use a commercially available alkaline water generator or the like, and connect the alkaline water discharge passage or acidic water discharge passage provided in the commercially available alkaline water generator or the like to the flow path 23 via an adapter or the like, so that the acidic water or alkaline water generated by the commercially available alkaline water generator or the like is discharged toward the hair H from the discharge port 21.

[0168] In addition, the specifications of the hair clamping portion, gripping portion, and other details (shape, size, layout, etc.) can also be changed as appropriate. [Industrial Applicability]

[0169] As described above, the hair iron according to the present disclosure is capable of improving the effect of hair treatment while minimizing the thermal damage that hair receives during treatment, and therefore can be used in a variety of hair irons, including those for home and commercial use.
