  The capacitor 45 is a capacitor that stores electric power from a commercial power source as electric charges for causing the irradiation unit 50 to emit light. The duty ratio of the power output from the capacitor 45 to the irradiation unit 50 is controlled by the control unit 15.

  FIG. 4 is a plan view showing a schematic configuration of the head unit 30 according to the embodiment. FIG. 5 is a cross-sectional view showing an internal configuration of the head unit 30 according to the embodiment.

  As shown in FIGS. 4 and 5, the head unit 30 includes an irradiation unit 50, a temperature detection unit 70, and a cooling unit 80.

  The irradiation unit 50 irradiates the skin S, which is an object, with a flashlight (hereinafter sometimes referred to as light). Specifically, the irradiation unit 50 irradiates a flashlight toward the irradiation port 110 provided at one end of the housing 21, thereby irradiating light on the object (skin S) facing the irradiation port 110. Irradiate. The irradiation port 110 is a light emitting region where the flashlight in the irradiation unit 50 emits light. The irradiation port 110 is formed in a long rectangular shape in plan view.

  The irradiation unit 50 includes a light source 51, a reflection unit 52, and a filter 53. The light source 51 is, for example, a linear tubular light source capable of flash emission, for example, a xenon lamp. The light source 51 is disposed in the vicinity of the center of the irradiation port 110 in the short direction so that the axial direction of the light source 51 is parallel to the longitudinal direction of the irradiation port 110.

  The reflection unit 52 is a reflector that reflects part of the light emitted from the light source 51 toward the irradiation port 110. The reflecting portion 52 has a concave space 521 that is open on the irradiation port 110 side, and the light source 51 is disposed in the concave space 521. The concave curved surface that forms the concave space 521 in the reflective portion 52 is a reflective surface.

  The filter 53 covers the open part of the concave space 521 and is an optical filter that adjusts the wavelength of light emitted from the light source 51. The light that has passed through the filter 53 becomes light in a wavelength band capable of exhibiting a hair suppression effect. The wavelength band capable of exhibiting the hair-burring effect is a wavelength band of 500 nm or more and 1200 nm or less that acts on hair melanin, and the wavelength band of 800 nm or more and 850 nm or less particularly contributes to the hair-burring effect. The ratio A / B between the integrated Eg (A) of light irradiation in the wavelength band of 800 nm to 850 nm and the integrated Eg (B) of light irradiation in the wavelength band of 500 nm to 600 nm is A / B ≧ 1.2 or more. The hair-loss effect can be obtained more effectively.

  The temperature detector 70 detects the temperature of the skin S. Specifically, the temperature detection unit 70 includes one or more (four in the present embodiment) contact-type temperature sensors 71. Examples of the contact type temperature sensor 71 include a contact type thermistor, a thermocouple, and a resistance temperature detector. The four temperature sensors 71 are arranged around the irradiation port 110. Of the four temperature sensors 71, the pair of temperature sensors 71 are arranged so as to sandwich the irradiation port 110 in the short direction of the irradiation port 110. The other pair of temperature sensors 71 are arranged so as to sandwich the irradiation port 110 in the longitudinal direction of the irradiation port 110.

  Here, it is desired to detect the temperature of the light receiving region in the skin S before and after the light irradiation. The light receiving region is a region facing the irradiation port 110 in the skin S, and is a region where treatment is performed. That is, if the temperature detection part is arrange | positioned in the irradiation port 110, the temperature of a light reception area | region can be detected reliably, but in that case, a temperature detection part will block light. If the temperature detection unit 70 is arranged around the irradiation port 110 as in the present embodiment, the temperature detection unit 70 can detect the temperature in the vicinity of the light receiving region without blocking light.

  The cooling unit 80 cools the skin S. For example, the cooling unit 80 is a thermoelectric element having a cooling function such as a Peltier element. The cooling unit 80 is disposed around the irradiation port 110. Specifically, the cooling unit 80 is disposed at a position where one temperature sensor 71 of the pair of temperature sensors 71 arranged in the short direction of the irradiation port 110 is sandwiched with the irradiation port 110. That is, the irradiation port 110 and the cooling unit 80 are arranged in the short direction of the irradiation port 110. The cooling unit 80 has a long rectangular shape in plan view, and is arranged so that its longitudinal direction is parallel to the longitudinal direction of the irradiation port 110. The outer surface of the cooling unit 80, the surfaces of the plurality of temperature sensors 71, and the peripheral edge of the irradiation port 110 in the housing 21 are substantially flush. Accordingly, when the irradiation port 110 is opposed to the skin S, the outer surface of the cooling unit 80, the surfaces of the plurality of temperature sensors 71, and the peripheral portion of the irradiation port 110 in the housing 21 are placed on the skin S. It can be adhered. If the outer surface of the cooling unit 80 is in close contact with the skin S, the skin S can be reliably cooled. If the surface of the temperature sensor 71 is in close contact with the skin S, the accuracy of temperature detection can be improved. If the peripheral edge of the irradiation port 110 in the housing 21 is in close contact with the skin S, leakage light can be suppressed.

  Next, the control configuration of the hair suppression device 10 will be described. FIG. 6 is a block diagram illustrating a control configuration of the hair suppression device 10 according to the embodiment.

  As shown in FIG. 6, the control unit 15 of the hair suppression device 10 is a microcomputer, and includes a first switch element 461, a second switch element 462, a lighting unit 43, a capacitor 45, a fan 31, a light source 51, and a temperature detection unit 70. The cooling unit 80 is electrically connected. The control unit 15 controls the light source 51, the lighting unit 43, the capacitor 45, and the fan 31 based on the control signal output from the first switch element 461.

  Specifically, when the power button 41 is operated and the control signal is input from the first switch element 461 when the power is turned off, the control unit 15 supplies the power from the commercial power source to each unit. On the other hand, when a control signal is input from the first switch element 461 by operating the power button 41 when the power is on, the control unit 15 stops supplying power from the commercial power source. The control unit 15 turns on the lighting unit 43 when the power is on, and turns off the lighting unit 43 when the power is off. The control unit 15 drives the fan 31 when the power is on and stops the fan 31 when the power is off. That is, when the power is turned on, the irradiation unit 50 is cooled by the fan 31.

  The control unit 15 drives the cooling unit 80 when the power is on, and stops the cooling unit 80 when the power is off. That is, the skin S is cooled by the cooling unit 80 when the power is turned on. The control unit 15 monitors the temperatures detected by the four temperature sensors 71 of the temperature detection unit 70 when the power is turned on, and when the detected temperature of at least one temperature sensor 71 is equal to or higher than a predetermined value, Irradiation of light from the irradiation unit 50 is prohibited. During this prohibition period, the control unit 15 does not accept a light emission signal input from the second switch element 462. In this case, the control unit 15 notifies the user that light irradiation is prohibited by making the lighting pattern of the lighting unit 43 different from the normal pattern.

  On the other hand, when the detected temperatures of the four temperature sensors 71 are less than the predetermined value, the control unit 15 permits the irradiation unit 50 to irradiate light. During this permission period, the control unit 15 receives the light emission signal input from the second switch element 462 and causes the light source 51 to emit light.

  Here, the higher the temperature of the skin S before the light irradiation, the more likely the skin S is damaged after the light irradiation. In particular, when light of the above-described wavelength band is irradiated to a portion (such as a chin or cheek) where thick hair such as a beard grows at a high density, the skin S becomes high temperature and is more easily damaged. For this reason, the “predetermined value” is a temperature at which the skin S is not significantly damaged even if the skin S is irradiated with light from the irradiation unit 50. Specifically, an appropriate value is determined in advance as the predetermined value by performing various simulations and experiments. The predetermined value varies depending on the irradiation Eg. For example, in irradiation Eg> = 8J, when the temperature of skin S is 25 degreeC or more, possibility that the said skin S will be damaged is high. Therefore, the predetermined value is 25 ° C. In consideration of the safety margin, the predetermined value is set to a value lower than 25 ° C. Specifically, the predetermined value is set to 15 ° C., for example.

[Control method]
Next, a method for controlling the hair suppression device 10 will be described. FIG. 7 is a flowchart showing a flow of a control method of the hair suppression apparatus 10 according to the present embodiment. This control method shows a flow after the power is turned on.

  In step S1, the control unit 15 drives the cooling unit 80 to cool the skin S. The control unit 15 continues driving the cooling unit 80 until the power is turned off.

  In step S <b> 2, the control unit 15 determines whether the detected temperatures of the four temperature sensors 71 have a detected temperature that is equal to or higher than a predetermined value. The control unit 15 proceeds to step S3 when the detected temperature of at least one temperature sensor 71 is equal to or higher than the predetermined value, and proceeds to step S5 when each detected temperature of the temperature sensor 71 is less than the predetermined value. To do. In step S <b> 3, the control unit 15 prohibits the irradiation unit 50 from irradiating light. During this prohibition period, the control unit 15 does not accept a light emission signal input from the second switch element 462. That is, since the light from the irradiation part 50 is not irradiated to the high temperature skin S, damage to the skin S can be prevented.

  In step S4, the control unit 15 controls the lighting unit 43 to light the lighting unit 43 with a lighting pattern different from the normal time. Thereby, the prohibition of irradiation is notified to the user. By visually recognizing the notification of the lighting unit 43 directly or through a mirror, the user knows that the current time is a prohibited period, that is, the temperature of the skin S is higher than a predetermined value. The user operates the hair suppressor 10 so that the skin S gets colder, promotes cooling of the skin S by the cooling unit 80, or uses the hair suppressor 10 until the temperature of the skin S becomes a predetermined value or less. It is possible to refrain or to apply another cooling means (ice, coolant, etc.) to the skin S. The control part 15 transfers to step S2 after alerting | reporting.

  In step S5, since the temperature detected by each temperature sensor 71 is less than a predetermined value and the safety against the skin S is secured to some extent, the control unit 15 permits the irradiation unit 50 to irradiate light.

  In step S6, the control unit 15 determines whether or not the light emission signal is input from the second switch element 462 during the permission period. If the light emission signal is not input, the control unit 15 proceeds to step S2 and performs the light emission signal. When is input, the process proceeds to step S5. Since the process proceeds to step S2 again during the permission period, when the temperature of the skin S rises from less than a predetermined value to more than a predetermined value due to some factor, it is switched to the prohibition period.

  In step S <b> 7, the control unit 15 controls the light source 51 to irradiate the skin S with light from the irradiation unit 50. As a result, the skin S is irradiated with flash light having a hair-loss effect.

[Effects, etc.]
As described above, the hair suppression device 10 according to the present embodiment includes the irradiation unit 50 that irradiates the object (skin S) with the flashlight, the temperature detection unit 70 that detects the temperature of the object, and the temperature detection unit. The control unit 15 controls the irradiation unit 50 based on the detected temperature of 70, and the control unit 15 prohibits the irradiation of the irradiation unit 50 when the temperature detected by the temperature detection unit 70 is equal to or higher than a predetermined value. .

  According to this, since the irradiation of the irradiation part 50 is prohibited when the temperature detected by the temperature detection part 70 is a predetermined value or higher, the light from the irradiation part 50 is irradiated to the skin S whose temperature has been increased. This can be prevented. Therefore, damage to the skin S can be prevented.

  Moreover, the hair suppression apparatus 10 is provided with the alerting | reporting part (lighting part 43), and the control part 15 performs the alerting | reporting by controlling the lighting part 43, when the detected temperature of the temperature detection part 70 is more than predetermined value. Make it.

  According to this, when the temperature detected by the temperature detection unit 70 is equal to or higher than the predetermined value, the lighting unit 43 notifies the user that the temperature of the skin S is equal to or higher than the predetermined value. . The user can take an appropriate action based on this notification.

  In addition, even if the temperature detected by the temperature detection unit 70 is equal to or higher than a predetermined value, even if the irradiation of the irradiation unit 50 is not prohibited, that is, when there is an abnormality in the prohibition process, the user is notified by the notification. It can be recognized that the temperature of S is equal to or higher than a predetermined value. Thereby, the user can restrain the operation with respect to the light emission button 42.

  Further, the hair suppression device 10 includes a cooling unit 80 that is disposed around a light emitting region (irradiation port 110) where the flashlight in the irradiation unit 50 emits light and cools the skin S.

  According to this, since the cooling unit 80 is provided around the irradiation port 110 of the irradiation unit 50, the periphery of the light receiving region of the skin S can be cooled by the cooling unit 80.

  In addition, the temperature detection unit 70 is disposed around the light emitting region where the flashlight in the irradiation unit 50 emits light.

  According to this, since the temperature detection unit 70 is provided around the irradiation port 110 of the irradiation unit 50, the temperature around the light receiving region of the skin S is set to the temperature without blocking the light irradiated from the irradiation port 110. It can be detected by the detection unit 70.

  The temperature detection unit 70 includes a contact type temperature sensor 71.

  According to this, since the temperature detection unit 70 includes the contact-type temperature sensor 71, the temperature of the skin S can be detected with a simple structure.

[Modification]
In addition, the structure of the hair suppression apparatus 10 is not limited to the structure demonstrated in the said embodiment. Therefore, in the following, a modified example of the hair suppression device will be described focusing on differences from the above embodiment. In the following description, the same parts as those in the above embodiment may be denoted by the same reference numerals and the description thereof may be omitted.

(Modification 1)
In the above embodiment, the case where the temperature detection unit 70 and the cooling unit 80 are fixed to the housing 21 is illustrated. In the first modification, a case where the temperature detection unit and the cooling unit are movable will be described.

  FIG. 8 is a plan view illustrating a schematic configuration of the head unit 30A according to the first modification. FIG. 9 is a cross-sectional view illustrating an internal configuration of the head unit 30A according to the first modification. FIG. 10 is a block diagram illustrating a control configuration of the hair suppression device 10A according to the first modification. Specifically, FIG. 8 is a diagram corresponding to FIG. 4, FIG. 9 is a diagram corresponding to FIG. 5, and FIG. 10 is a diagram corresponding to FIG.

  As shown in FIGS. 8 and 9, the temperature detection unit 70a and the cooling unit 80a included in the head unit 30A are slidably held by a slide unit 85a. The slide part 85a includes a holding frame 86a that holds the temperature detection part 70a and the cooling part 80a, and a drive source 87a (see FIG. 10) for sliding the holding frame 86a. Examples of the drive source 87a include a motor and a solenoid.

  An irradiation port 110a is formed in the holding frame 86a. The holding frame 86a slides along the short direction of the irradiation port 110a while maintaining the relative positional relationship between the four temperature sensors 71a of the temperature detection unit 70a and the cooling unit 80a. Specifically, the holding frame 86a is connected to the drive source 87a via a slide mechanism (not shown). When the drive source 87a is driven, the slide mechanism operates and the holding frame 86a slides. By the slide of the holding frame 86a, the installation locations of the four temperature sensors 71a and the cooling unit 80a are switched between the first position and the second position.

  8 and 9, the case where the four temperature sensors 71a and the cooling unit 80a are in the first position is illustrated by solid lines. The case where the four temperature sensors 71a and the cooling unit 80a are in the second position is indicated by broken lines. In FIGS. 8 and 9, the holding frame 86a in the second position is not shown.

  The first position is an installation location of the four temperature sensors 71 a and the cooling unit 80 a when light is irradiated from the irradiation unit 50. In the first position, the irradiation port 110 a of the holding frame 86 a faces the irradiation unit 50. For this reason, the light irradiated from the irradiation part 50 passes through the irradiation port 110a and reaches the light receiving region of the skin S.

  The second position is an installation location of the four temperature sensors 71a and the cooling unit 80a when the light receiving area of the skin S is cooled by the cooling unit 80a. In the second position, the cooling unit 80 a faces the irradiation unit 50.

  As shown in FIG. 10, the drive source 87 a of the slide portion 85 a is electrically connected to the control unit 15 and is driven based on the control of the control unit 15. For example, the control unit 15 controls the drive source 87a when it is in the permission period, and installs the four temperature sensors 71a and the cooling unit 80a at the first position. Thereafter, when a light emission signal is input from the second switch element 462, the control unit 15 controls the light source 51 to irradiate the skin S with light from the irradiation unit 50.

  On the other hand, the control part 15 controls the drive source 87a, when it is in a prohibition period, and installs the four temperature sensors 71a and the cooling part 80a in a 2nd position. For this reason, the cooling unit 80a faces the light receiving region of the skin S, and the light receiving region can be directly cooled by the cooling unit 80a. In addition, even if light is irradiated from the irradiation unit 50 during the prohibition period, the cooling unit 80a blocks the light, and thus the safety against the skin S can be ensured.

  As described above, the hair suppression device 10A according to the first modification includes the slide portion 85a that slides the temperature detection unit 70a and the cooling unit 80a. Therefore, the temperature detection unit can be moved without moving the hair suppression device 10A. 70a and the cooling unit 80a can be moved. Thereby, the skin S can be cooled efficiently without bothering the user.

(Modification 2)
In the said embodiment, the case where the temperature detection part 70 included the contact-type temperature sensor 71 was illustrated. In the second modification, a case where the temperature detection unit includes a non-contact type temperature sensor is illustrated.

  FIG. 11 is a plan view illustrating a schematic configuration of a head unit 30B according to the second modification. Specifically, FIG. 11 corresponds to FIG.

  As shown in FIG. 11, the temperature detection unit 70b includes two sets of non-contact temperature sensors 71b. The two sets of temperature sensors 71b are disposed in the vicinity of both ends in the longitudinal direction of the irradiation port 110. The non-contact type temperature sensor 71b includes a light emitting element 711b that emits infrared light and a light receiving element 712b that receives the infrared light emitted from the light emitting element 711b. The light emitting element 711b and the light receiving element 712b are arranged so as to sandwich the irradiation port 110 in the short direction. That is, the infrared rays emitted from the light emitting element 711b pass through the light receiving region of the skin S and reach the light receiving element 712b. Since the light receiving element 712b outputs a signal corresponding to the intensity of the received infrared light, the temperature of the light emitting region of the skin S can be detected based on the signal.

  Thus, the temperature detection part 70b which concerns on the modification 2 contains the non-contact-type temperature sensor 71b. Since the temperature detection unit 70b includes the contact-type temperature sensor 71b, the temperature of the light receiving region of the skin S can be reliably detected.

(Modification 3)
In the said embodiment, the case where the cooling part 80 was a thermoelectric element with a cooling function was illustrated. In Modification 3, a cooling unit that performs cooling with a coolant will be described.

  FIG. 12 is a cross-sectional view illustrating an internal configuration of a head unit 30C according to the third modification. Specifically, FIG. 12 corresponds to FIG.

  As shown in FIG. 12, the cooling unit 80 c included in the head unit 30 </ b> C includes a cold insulation unit 81 c and a discharge unit 82 c in the housing 21. The cold insulation unit 81c is a storage that keeps the coolant C cold. Examples of the coolant C include gel agents. The cold insulation unit 81c keeps the coolant C at a predetermined temperature or lower (for example, 15 ° C. or lower). A through-hole 811c communicating with the irradiation port 110 is formed at the bottom of the cold insulator 81c.

  The discharge part 82c is a pusher that pushes out the coolant C in the cold insulation part 81c, and moves up and down based on the drive of a drive source (not shown). The drive source is driven based on the control of the control unit 15. When the discharge part 82c is lowered by driving the drive source, the coolant C in the cold insulation part 81c is pushed out from the through hole 811c and filled in the irradiation port 110. Thereby, the light receiving region of the skin S is cooled by the coolant C. Even in this case, when the temperature detected by the temperature detection unit 70 is equal to or higher than the predetermined value, the irradiation of the irradiation unit 50 is prohibited. When the temperature detected by the temperature detection unit 70 is lower than the predetermined value, the irradiation unit 50 Irradiation is allowed.

  As described above, the cooling unit 80c according to the modification 3 includes the cold insulation unit 81c that keeps the coolant C cold and the discharge unit 82c that discharges the coolant C in the cold insulation unit 81c toward the skin S.

  According to this, since the coolant C can be directly discharged to the light receiving area of the skin S, the light receiving area of the skin S can be reliably cooled without moving the cold insulation portion 81c. In addition, since the light receiving region of the skin S is covered with the coolant C even during the light irradiation, the light can be irradiated with the skin S protected by the coolant C.

  The cooling unit is not limited to those described above, and may be a cooling unit such as an air cooling type or a water cooling type.

[Others]
As mentioned above, although the hair suppression apparatus which concerns on this invention was demonstrated based on the said embodiment and modification, this invention is not limited to the said embodiment and modification.

  For example, in the above embodiment, the case where the light emission signal is input from the second switch element 462 to the control unit 15 due to the operation of the light emission button 42 has been illustrated. However, for example, in the control unit 15, the light emission signal may be automatically generated at a predetermined timing when the power is turned on. Also in this case, the control unit 15 does not accept the light emission signal when it is the prohibition period, and accepts the light emission signal when it is the permission period.

  Moreover, the case where the irradiation part 50 has the one light source 51 was illustrated. However, the number of installed light sources 51 may be two or more.

  Moreover, in the said embodiment, the lighting part 43 which performs visual alerting | reporting was illustrated as an alerting | reporting part.
