Description

Technical Field

[0001] This invention relates to a hair curling device. Background Technology

[0002] Patent Document 1 discloses a conventional hair curler. This hair curler can heat the pressing body that contacts the hair by radiating light from a light source, and irradiate the hair with the radiated light, thereby directly heating the hair. The hair curler of Patent Document 1 can irradiate the hair with radiated light through an anti-glare filter that absorbs visible light below 700nm, thus preventing glare from the radiated light, and mainly irradiating the hair with infrared rays from the radiated light component to directly heat the hair.

[0003] Existing technical documents Patent documents Patent Document 1: Japanese Patent Application Publication No. 2023-101828 Summary of the Invention The problem the invention aims to solve Preferably, if the hair and scalp can be illuminated during the use of the hair curler, the hair can be styled while checking the condition of the hair and scalp. For example, in the hair curler of Patent Document 1, if the structure removes the anti-glare filter, the hair and scalp can be illuminated by radiated light. However, if the temperature of the pressing body is set low, the amount of radiated light is suppressed, and in this case, it may become impossible to illuminate the hair and scalp by radiated light.

[0004] The present invention is based on the above-mentioned prior practice, and the problem it seeks to solve is to provide a hair curler that can effectively illuminate the hair and scalp.

[0005] means for solving problems The hair curling iron of the present invention has a pair of arms extending from a base to a front end, configured to be connected at the base end side and freely openable and closable at the front end side. The hair curling iron includes: a clamping part disposed at the front end side of each arm for clamping hair; and a holding part disposed at the base end side of each arm for holding hair when clamping; the clamping part includes: a heating part having a pair of plates and a pair of heat sources, the pair of plates having clamping surfaces for clamping hair, the pair of heat sources being respectively disposed on each plate and heating each plate; and an illumination part illuminating the area being styled during styling; the illumination part is lit while each plate is heated by each heat source.

[0006] The lighting unit of this hair curler is separated from the heating unit, thus maintaining a consistent light intensity regardless of temperature changes in the heating unit, and radiating light onto the area being styled. Furthermore, the lighting unit illuminates while each plate is heated by its respective heat source, allowing the user to visually confirm the plate is hot by checking the lighting unit's illumination.

[0007] Therefore, this hair curler is able to effectively brighten the hair and scalp. Attached Figure Description

Detailed Implementation

[0017] The following describes preferred embodiments of the present invention.

[0018] In the hair curling device of the present invention, the illumination unit has a light source for radiating light and a light-emitting surface through which the light passes, and the light-emitting surface can be configured to expose an edge extending from the base end side to the front end side in the clamping unit. In this case, when the clamping unit clamps the hair, light can be radiated toward the hair extending from the clamping unit.

[0019] In the hair curler of the present invention, the light-emitting surface is capable of radiating light outward in the direction of the opposing plates of the pair of plates. In this case, when the hair is clamped by the clamping part, light can be effectively radiated toward the hair extending from the clamping part.

[0020] <Example 1> Hereinafter, with reference to the accompanying drawings, Embodiment 1, which embodies the present invention, will be described. Figure 1 , Figure 2 As shown, the hair curler 10 of this embodiment 1 has a pair of arms 10A and 10B. The pair of arms 10A and 10B extend from the base end 11 to the front end 12, respectively. The pair of arms 10A and 10B are connected at the base end 11 and can be freely opened and closed at the front end 12. The hair curler 10 is capable of opening the pair of arms 10A and 10B, clamping hair between the arms 10A and 10B, and applying heat to the hair to style it. When not in use, the hair curler 10 is in a closed state (see reference). Figure 1 The outer casing component (not shown) detachably covers the front end portion 12 of a pair of arms 10A, 10B.

[0021] Hereinafter, the open state of the pair of arms 10A and 10B in the hair curler 10 will be referred to as the open state (see reference). Figure 2 The closed state refers to the state in which a pair of arms 10A and 10B are closed (see reference). Figure 1The directions used in the descriptions of each structural member are based on the closed state of a pair of arms 10A and 10B. In the coordinate axes shown in the figures, the positive direction of the Z-axis indicates upward, the negative direction of the Z-axis indicates downward, the positive direction of the X-axis (towards the front end 12 of arms 10A and 10B) indicates forward, the negative direction of the X-axis (towards the base end 11 of arms 10A and 10B) indicates backward, the positive direction of the Y-axis indicates right, and the negative direction indicates left. The forward and backward direction is also called the extension direction of arms 10A and 10B, and the left and right direction is also called the width direction of arms 10A and 10B. In the descriptions of each arm 10A and 10B, the opposing sides of a pair of arms 10A and 10B are referred to as the inner or outer side, and the opposite side of the opposing sides is referred to as the outer or back side. That is, the up and down direction is also the inner and outer direction or the outer and back direction of arms 10A and 10B.

[0022] like Figure 2 As shown, a pair of arms 10A and 10B rotate relative to each other about a hinge portion 13A located at the base end 11. A compression coil spring 13B extending in the vertical direction is provided between the pair of arms 10A and 10B and in front of the hinge portion 13A.

[0023] A pair of arms 10A and 10B each have an outer shell 16A, an inner shell 16B, a gripping decorative plate 16C, a clamping decorative plate 16D, and a cap 16E. The outer shell 16A is made of synthetic resin. The outer shell 16A has a width in the left-right direction and extends in the front-back direction. The outer shell 16A of the upper arm 10A is formed such that its central portion in the left-right direction is located above the two ends in the left-right direction and bulges upward (see reference). Figure 3 The outer shell 16A of the lower arm 10B is formed such that the central portion in the left-right direction is located below the two ends in the left-right direction and bulges downward (see reference). Figure 3 ).

[0024] On the front side of the outer casing 16A, light guide member insertion holes 16F are formed on the left and right edges respectively, extending in the left and right directions (see reference). Figure 3 ).like Figure 5 As shown, the light guide member insertion hole 16F is elongated in the front-to-back direction. To prevent deformation of the light guide member insertion hole 16F, a plurality of reinforcing posts 16G are provided on the outer housing 16A. These reinforcing posts 16G are arranged at equal intervals in the front-to-back direction, forming a shape that connects the upper and lower sides of the light guide member insertion hole 16F.

[0025] Multiple support walls 16H are provided on the outer housing 16A, facing the light guide member insertion hole 16F from the inside in the left and right directions. In the left and right direction, these support walls 16H and reinforcing posts 16G are arranged at a predetermined distance.

[0026] The inner shell 16B is made of synthetic resin. The inner shell 16B has a width in the left-right direction and extends in the front-back direction. At the upper arm 10A, as... Figure 2 As shown, the inner housing 16B is mounted facing the rear side (base end 11 side) of the outer housing 16A from below. At the lower arm portion 10B, the inner housing 16B is mounted facing the rear side (base end 11 side) of the outer housing 16A from above.

[0027] If the inner housing 16B is installed on the rear side of the outer housing 16A, then as Figure 4 As shown, an opening region R is formed, which is a rectangle that extends in the front-to-back direction. The front edge and the left and right end edges of the opening region R are defined by the outer shell 16A, and the rear edge is defined by the inner shell 16B. Vertical walls 16K are provided at the front and rear ends of the opening region R. Specifically, the vertical wall 16K provided at the front end of the opening region R rises along the front ends of the front edge and the left and right end edges of the opening region R. The vertical wall 16K provided at the rear end of the opening region R rises along the rear ends of the rear edge and the left and right end edges of the opening region R. Figure 4 The outer housing 16A and inner housing 16B at the lower arm portion 10B are shown, while at the upper arm portion 10A, the opening region R and the vertical wall 16K are also formed in the same shape as the lower arm portion 10B. The heating element 21, which will be described later, is disposed in the opening region R in an exposed manner.

[0028] The handle trim panel 16C is made of synthetic resin. The handle trim panel 16C is wide in the left-right direction and extends in the front-back direction. At the upper arm portion 10A, as... Figure 2 As shown, the grip trim panel 16C is installed from above, covering the rear side (base end 11 side) of the outer housing 16A. At the lower arm portion 10B, the grip trim panel 16C is installed from below, covering the rear side (base end 11 side) of the outer housing 16A.

[0029] The clamping part decorative panel 16D uses, for example, a so-called synthetic resin felt made by compressing and forming fibers of synthetic resin into a sheet. At the upper arm portion 10A, the clamping part decorative panel 16D is mounted from above, covering the front side (front end portion 12 side) of the outer housing 16A (see reference). Figure 2 , Figure 3 At the lower arm portion 10B, the clamping decorative plate 16D is mounted such that it covers the front side (front end portion 12 side) of the outer housing 16A from below (see reference). Figure 2 , Figure 3The clamping part decorative panel 16D uses a synthetic resin felt, so it is difficult for the user to feel heat when touching it.

[0030] The cap portion 16E is made of synthetic resin. The cap portion 16E is shaped to extend in the left-right direction (see reference). Figure 1 The cap 16E is mounted so as to cover the front ends 12 of each arm 10A, 10B from the front.

[0031] The hair curler 10 has a clamping part 20 and a holding part 30. The clamping part 20 is provided on the front end 12 side (front end side) of a pair of arms 10A, 10B, and is capable of clamping hair.

[0032] [Structure of the clamping part] like Figure 3 As shown, the clamping part 20 includes a heating part 21, a pair of supports 51, multiple elastic members 52, and an illumination part 22. The illumination part 22 illuminates the area being styled, i.e., the hair and scalp, during styling. The heating part 21 includes: a pair of plates 40 with clamping surfaces 20A for holding the hair, and a pair of heat sources 50, each disposed on and heating the plates 40. The pair of plates 40 are made of, for example, aluminum. Each plate 40 is formed as a flat plate with its thickness direction facing vertically. Each plate 40 has a clamping surface 20A. The clamping surfaces 20A face each other vertically. The pair of clamping surfaces 20A are surfaces that contact and clamp the hair. Each plate 40 protrudes inward beyond the opening area R formed by the outer shell 16A and the inner shell 16B.

[0033] A pair of heat sources 50 are respectively disposed on opposite sides of the clamping surface 20A of each plate 40. The heat sources 50 are, for example, known ceramic heaters. The heat sources 50 are heated by being supplied with electricity, thereby heating the plates 40.

[0034] A pair of brackets 51 are made of, for example, synthetic resin. Each bracket 51 corresponds to each plate 40. Each bracket 51 is positioned on the opposite side of the clamping surface 20A of each plate 40. Each plate 40 is mounted on each bracket 51. The heat source 50 is clamped from above and below by the brackets 51 and the plates 40.

[0035] Multiple elastic members 52 are made of rubber, for example, formed in the shape of a frustum cone. Two elastic members 52 are attached to the inner side of each outer shell 16A in a manner separated in the front-rear direction (see reference). Figure 2Each elastic member 52 has a through hole 52A extending vertically. A boss 51A provided on the bracket 51 is pressed into each through hole 52A. In this way, the plate 40 is connected to the outer shell 16A via the elastic member 52. If a force toward the rear side is applied to each plate 40, the elastic member 52 is flattened in the vertical direction. As a result, each plate 40 is displaced in the vertical direction toward the outer shell 16A to which it is connected. If no force toward the rear side is applied to each plate 40, the elastic member 52 elastically returns to its original position. As a result, the relative position of each plate 40 with respect to the outer shell 16A to which it is connected returns to its original position.

[0036] like Figure 5 As shown, the lighting unit 22 includes multiple light sources 22A that emit light, multiple light guide members 22B, multiple light-emitting surfaces 22K for light transmission, and multiple light-shielding sheets 22C. Each light source 22A uses, for example, an LED that is heat-resistant and emits white light. These light sources 22A are mounted on the surface of one side of a substrate 22D that extends in the front-rear direction. The substrate 22D uses a known printed circuit board. The substrate 22D on which the light sources 22A are mounted is positioned such that the light sources 22A are facing outward in the left-right direction, and is inserted between the reinforcing post 16G and the support wall 16H in the outer housing 16A (see reference). Figure 6 , Figure 7 Therefore, each light source 22A is configured to face each other from the inside of the left and right directions relative to the light guide member insertion hole 16F (see reference). Figure 6 , Figure 7 ).

[0037] Multiple light guide components 22B are made, for example, of a colorless and transparent synthetic resin with a small amount of diffusing agent added. Each light guide component 22B is formed to extend in the front-back direction. Each light guide component 22B has multiple insertion portions 22E that are inserted into the light guide component insertion hole 16F, multiple locking claws 22F, and anti-dislodgement bosses 22G. Each insertion portion 22E is shaped to protrude inward in the left-right direction and is arranged in the front-back direction. The protruding end at each insertion portion 22E is formed into a facing surface 22H facing each light source 22A. Each facing surface 22H is formed in a concave-convex shape (see reference). Figure 6 , Figure 7 If the light emitted from each light source 22A is incident on each phase-facing surface 22H, it will be refracted in each direction and reach each place in the light guide component 22B.

[0038] Each insertion portion 22E is provided with a locking claw 22F. Each locking claw 22F protrudes inward in the left-right direction from the insertion portion 22E. An anti-disengagement boss 22G is provided in the insertion portion 22E at the center in the front-back direction. The anti-disengagement boss 22G is integrally formed with the locking claw 22F and protrudes inward in the left-right direction from the locking claw 22F (see reference). Figure 7When the light guide component 22B is installed in the light guide component insertion hole 16F, each insertion part 22E is inserted into the light guide component insertion hole 16F in a manner that avoids the reinforcing post 16G (see reference). Figure 7 Furthermore, each locking claw 22F engages with the locking protrusion 16J provided on the outer housing 16A (see reference). Figure 6 The anti-detachment boss 22G inserts through the through hole 22J, which is formed on the substrate 22D. The substrate 22D is disposed between the reinforcing post 16G and the support wall 16H (see reference). Figure 7 This prevents the substrate 22D from detaching from the reinforcing pillar 16G and the support wall 16H.

[0039] With the light guide component 22B installed in the light guide component insertion hole 16F, the multiple light-emitting surfaces 22K are the surfaces exposed on the outside of each light guide component 22B (see reference). Figure 6 , Figure 7 Each light-emitting surface 22K is configured to expose the left and right side edges extending from the base end 11 side to the front end 12 side in the clamping portion 20 (see reference). Figure 4 ).like Figure 3 As shown, each emitting surface 22K faces outward in the left-right direction from the opposing plates 40 of the pair of plates 40. Therefore, the light L emitted outward through the emitting surface 22K travels outward in the left-right direction (outer direction) from the opposing plates 40 of the pair of plates 40. In other words, the emitting surface 22K emits light L in the outward direction from the opposing plates 40 of the pair of plates 40. When a hair H is held between a pair of clamping surfaces 20A, the light L emitted from the emitting surface 22K can illuminate the hair H extending from the plates 40 in the left-right direction. In the front-back direction, as... Figure 8 As shown, the front end of the light-emitting surface 22K is positioned approximately at the same location as the front end of the plate 40. In the front-rear direction, the rear end of the light-emitting surface 22K is positioned further forward than the rear end of the plate 40.

[0040] With the light guide component 22B installed in the light guide component insertion hole 16F, the reinforcing post 16G is covered from the outside by the light guide component 22B (see reference). Figure 7 A diffusing agent is added to the light guide component 22B, causing light emitted from each light source 22A to refract in various directions upon incident on each opposing surface 22H, reaching various locations within the light guide component 22B. Therefore, light is uniformly emitted from the emitting surface 22K, resulting in an inconspicuous light spot that is difficult for the user to perceive the presence of the reinforcing pillar 16G. Furthermore, since the reinforcing pillar 16G is not exposed, compared to a situation where the reinforcing pillar is exposed, the light guide component 22B appears not to be divided by the reinforcing pillar 16G.

[0041] Multiple light-shielding sheets 22C are, for example, formed in a flat plate shape and made of silicone rubber. Figure 5As shown, each light-shielding plate 22C is formed as a rectangle that is longer in the front-to-back direction. Figure 6 As shown, each light-shielding sheet 22C is attached to a substrate 22D, which is positioned between the reinforcing post 16G and the support wall 16H. Specifically, one end edge of the light-shielding sheet 22C along its length is brought into contact with the surface of the substrate 22D on which the light source 22A is mounted, and the light-shielding sheet 22C is attached to the side of the light source 22A facing the heating element 21. Furthermore, the other end edge of the light-shielding sheet 22C along its length is attached to the inner surface of the left edge (right edge) of the opening region R in the outer housing 16A. In this way, by attaching the light-shielding sheet 22C, light emitted from the light source 22A is prevented from leaking out of the opening region R.

[0042] [Structure of the holding part] like Figure 2 As shown, the gripping part 30 is located at the base end 11 (rear end) of one of the pair of arms 10A and 10B, and is gripped by the user when clamping hair. A locking part 13C that slides freely in the front-back direction is provided at the base end 11 of the gripping part 30. If the locking part 13C is slid backward, the pair of arms 10A and 10B are held in an open state by the elastic repulsive force of the compressed coil spring 13B. At this time, the pair of arms 10A and 10B can freely move between the open and closed states by the user controlling the force applied to the gripping part 30. If the locking part 13C is slid forward while the pair of arms 10A and 10B are in the closed state, the pair of arms 10A and 10B are held in the closed state (see reference). Figure 1 A power cord 90 with a power plug (not shown) is provided at the base end 11 of the gripping part 30. Figure 1 As shown, the width of the clamping part 20 in the left-right direction is larger than the width of the gripping part 30 in the left-right direction.

[0043] like Figure 1 As shown, the hair curler 10 has a display section 14. The display section 14 is located on the outer surface of the handle section 30 in the lower arm section 10B. The display section 14 is... Figure 1 The area enclosed by a square shape marked with dashed lines. The gripping part 30 in the lower arm 10B houses a control board (not shown). The control board is, for example, a known printed circuit board. A microcomputer (not shown) and multiple LEDs are mounted on the surface of the control board for controlling various parts of the hair curler 10. Light emitted from these LEDs passes through the display section 14 and is emitted to the outside. The display section 14 is configured to allow light to pass through, displaying predetermined content such as the power on / off state and set temperature. The predetermined display content includes text, numbers, symbols, icons, and patterns.

[0044] For example, the components constituting the display unit 14 are made of transparent or translucent synthetic resin. The surface or back of the components constituting the display unit 14 is coated with black. By removing a portion of the black coating (so-called cutout), the components constituting the display unit 14 form the prescribed display content. Then, a paint of a prescribed color other than black (e.g., a light color or white) is applied to the entire surface of the display unit 14. Therefore, when the LED is off, the prescribed display content cannot be visually confirmed from the outside, but it appears when the LED is lit and can be visually confirmed from the outside.

[0045] like Figure 1 As shown, a power button 19A, a down button 19B, and an up button 19C are provided on the handle 30. The power button 19A, down button 19B, and up button 19C are arranged between the upper arm 10A and the lower arm 10B; in other words, they are arranged in the front-to-back direction at the center of the handle 30 in the vertical direction. Switches (not shown) corresponding to the power button 19A, down button 19B, and up button 19C are mounted on the surface of the control board. These switches are, for example, known tact switches or membrane switches. Pressing the power button 19A switches the power supply to the hair curler 10 on and off. Pressing the down button 19B and the up button 19C switches the temperature of the plate 40 to the desired temperature. Operating the power button 19A to turn on the power begins the heating of the plate 40, as described later. The hair curler 10 allows the temperature of the plate 40 to be set to one of several temperature settings by operating the down button 19B or the up button 19C. For example, the set temperature can be selected from any of five temperatures: 120 degrees, 140 degrees, 160 degrees, 180 degrees, and 200 degrees. For instance, pressing the up button 19C once selects a temperature one step higher than the currently selected temperature, while pressing the down button 19B once selects a temperature one step lower than the currently selected temperature.

[0046] Next, the function of the hair curler 10 in this embodiment will be explained.

[0047] First, the user connects the power plug (not shown) to the socket on the power cord 90. Then, the user removes the housing component (not shown) covering the front ends 12 of the pair of arms 10A and 10B. Next, the user slides the locking part 13C backward. The pair of arms 10A and 10B are then held in an open position by the elastic repulsive force of the compressed coil spring 13B (see reference). Figure 2 ).

[0048] Then, the user presses the power button 19A for a specified time (e.g., 2 seconds). Power is then supplied to the heat source 50, initiating the heating of the board 40. Simultaneously, power is also supplied to the light source 22A, and light begins to radiate from it. After pressing the power button 19A, the user can set the temperature of the board 40 to the desired setting temperature by pressing either the down button 19B or the up button 19C within a specified time (e.g., within 5 seconds).

[0049] For example, a known thermocouple (not shown) is provided on board 40, and a control unit (not shown) mounted on the surface of the control substrate is configured to detect the temperature of board 40. When board 40 is heating up or cooling down to reach a set temperature, the control unit causes the LED corresponding to the selected set temperature to flash red on display unit 14, and the LED corresponding to the unselected set temperature to light up white. Furthermore, if the control unit detects that the temperature of board 40 has reached the set temperature via the thermocouple, it lights up the LED corresponding to the selected set temperature in red on display unit 14. Preferably, the condition for the LED corresponding to the selected set temperature to light up red is that the difference between the temperature detected by the thermocouple and the set temperature is less than a predetermined difference (e.g., less than 10 degrees Celsius). If the state of not operating the down button 19B or the up button 19C continues for a predetermined time or longer (e.g., 5 seconds or longer), changing the set temperature via the control unit is prohibited. At the same time, the control unit illuminates the LED in the display unit 14 that corresponds to the display content indicating that changes to the set temperature are prohibited (e.g., a padlock icon) in white.

[0050] If the setting temperature is changed again after the restriction on changing the setting temperature has been lifted, pressing the down button 19B or the up button 19C for a specified time (e.g., 2 seconds or more) will lift the restriction on changing the setting temperature, causing the LED (padlock icon) on the display unit 14 corresponding to the display content indicating that the setting temperature has been fixed to turn off. The user can then operate the down button 19B or the up button 19C to reset the setting temperature to the desired value.

[0051] Next, the user of the hair curler 10 inserts the clamping part 20 into the hair from the front end 12 side. When the desired amount of hair is positioned in the clamping part 20, the user holds the handle 30 and closes the pair of arms 10A, 10B. Thus, the hair H is clamped by the pair of clamping surfaces 20A (see reference). Figure 3 At this time, the plate 40 is connected to the outer shell 16A via the elastic member 52, so even if the user grips the handle 30 with great force, the hair can be prevented from being excessively pressed by the pair of clamping surfaces 20A.

[0052] The light L emitted from the emitting surface 22K travels outward in the left-right direction from the opposing plates 40 of the pair of plates 40 (refer to...). Figure 3 The light L emitted through the luminous surface 22K can illuminate the hair H extending to the left and right from the plate 40 and the scalp (not shown) (see reference). Figure 3 This allows users to style their hair while simultaneously checking the condition of the hair shaft and scalp.

[0053] When the user styles the hair using the hair curler 10, the hair H is positioned in a direction that intersects the opening area R in the left-right direction (see reference). Figure 3 , Figure 4 In other words, during the styling of the hair, the hair H disposed in the clamping part 20 moves in the left and right directions in the opening region R. Therefore, the hair H becomes easy to enter the interior through the gap formed at the front edge and the rear edge of the opening region R, but by providing the vertical wall 16K along the front edge and the rear edge of the opening region R, it is possible to prevent the hair H from entering the interior through the gap formed at the end edge and the rear edge of the opening region R.

[0054] After using the hair curler 10, the user presses the power button 19A to cut off the power. This stops the power supply to the heat source 50, the light source 22A, and the LEDs of the display unit 14, halting the heating of the plates 40 by the heat source 50. Simultaneously, the light source 22A and the LEDs of the display unit 14 turn off. That is, the illumination unit 22 is lit while each plate 40 is being heated by its respective heat source 50. Afterward, with the arms 10A and 10B in the closed state, the locking part 13C is slid forward to hold the arms 10A and 10B in the closed state (see reference). Figure 1 Then, the housing component (not shown) is used to cover the clamping part 20. The user then removes the power plug (not shown) from the socket, which is attached to the power cord 90.

[0055] As described above, the hair curler 10 has a pair of arms 10A and 10B, which extend from the base to the front end and are connected at the base and can be freely opened and closed at the front end. The hair curler 10 includes a clamping part 20 disposed at the front end of each arm 10A and 10B and capable of clamping hair, and a holding part 30 disposed at the base end of each arm 10A and 10B and held when clamping hair. The clamping part 20 has a heating part 21 and an illumination part 22. The heating part 21 has a pair of plates 40 and a pair of heat sources 50. The plates 40 have clamping surfaces 20A for clamping hair. The heat sources 50 are respectively disposed on each plate 40 and heat each plate 40. The illumination part 22 illuminates the area being styled during styling. The illumination part 22 is lit while each plate 40 is heated by each heat source 50.

[0056] The lighting section 22 of the hair curler 10 is separate from the heating section 21, so it can be configured to maintain the amount of light and emit light without being affected by the temperature changes of the heating section 21. In addition, while each plate 40 is heated by each heat source 50, the lighting section 22 maintains the emission of light, so the user can visually confirm that the plate 40 is hot by visually confirming the emission of light.

[0057] Therefore, the hair curler 10 can effectively heat up the hair and scalp.

[0058] In the hair curler 10, the lighting unit 22 has a light source 22A that radiates light and a light-emitting surface 22K that allows light to pass through. The light-emitting surface 22K is configured such that an edge extending from the base end side to the front end side in the clamping part 20 is exposed. Therefore, it can be configured to radiate light toward the hair extending from the clamping part 20 when the clamping part 20 clamps the hair.

[0059] In the hair curler 10, the light-emitting surface 22K radiates light outward toward the opposing plates 40 of a pair of plates 40. Therefore, when the clamping part 20 clamps the hair, it is possible to radiate light effectively toward the hair extending from the clamping part 20.

[0060] <Other Embodiments> The present invention is not limited to the contents of Embodiment 1 described above and illustrated in the accompanying drawings. For example, the following embodiments are also included within the technical scope of the present invention.

[0061] (1) Unlike Embodiment 1, the light emission color of the illumination unit can change with the temperature of the board. In this case, thermocouples are provided on each board, and the temperature of the board is monitored at the control board. For example, when the power plug is connected to the socket, if the temperature of the board is below 50 degrees, the illumination unit is lit in white. In addition, if the temperature of the board is greater than 50 degrees and about 10 degrees lower than the set temperature, the illumination unit is lit in blue or flashes. Moreover, if the temperature of the board is in the range of about 10 degrees lower than the set temperature to about 10 degrees higher than the set temperature, the illumination unit is lit in red. Furthermore, the illumination unit can be used to report errors. For example, if no power is supplied to the heat source, the illumination unit can flash red. If power is supplied to the heat source, if the temperature of the board does not reach the set temperature even after a specified time (e.g., after 3 minutes), the illumination unit can flash blue and white alternately. If the temperature difference between the boards is greater than a specified difference (e.g., more than 10 degrees), the illumination unit can flash blue and red alternately. In addition, if the power supply has been continuously on for a specified period of time, the lighting unit can be made to flash white starting a short period of time (e.g., 1 minute before the automatic disconnection function that automatically switches the power supply to the off state is executed).

[0062] (2) Unlike Example 1, it can be configured to expose the reinforcing pillars. In this case, the light-emitting surface is in a state of being divided by the reinforcing pillars.

[0063] (3) Unlike Example 1, red, green and blue LEDs can be used in sequence as light sources.

[0064] (4) Unlike Embodiment 1, an illumination unit can be provided in the clamping portion via a flexible arm. Power supply to the illumination unit is preferably provided via wires arranged within the flexible arm. For example, the flexible arm can be configured to extend from the upper surface of the clamping portion at the upper arm or the lower surface of the clamping portion at the lower arm. In this case, the flexible arm can be bent into a desired shape, allowing for free change of the orientation of the emitted light at the illumination unit.

[0065] (5) Unlike Example 1, the light source can be configured to be disposed on each light guide component.

[0066] (6) Unlike Example 1, light transmitted through the light-emitting surface can be radiated toward the clamping surface of the plate.

[0067] (7) Unlike Embodiment 1, the light emission color of the illumination unit can be light other than white. For example, it can emit red, blue, yellow, etc. If the light emission color of the illumination unit is red, it can be expected to improve the wrinkles of the skin; if it is blue, it can be expected to improve the dullness of the skin; and if it is yellow, it can be expected to improve the pigmentation of the skin. That is, different effects can be given to the skin depending on the light emission color of the illumination unit.
