FIG. 4 is a plan view showing a schematic configuration of the head portion 30 according to the embodiment. FIG. 5 is a cross-sectional view showing the internal configuration of the head portion 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, may be referred to as light). Specifically, the irradiation unit 50 irradiates the flashlight toward the irradiation port 110 provided at one end of the housing 21 to irradiate the object (skin S) facing the irradiation port 110 with light. Irradiate. The irradiation port 110 is a light emitting region in which the flashlight in the irradiation unit 50 emits light. The irradiation port 110 is formed in a long rectangular shape in a 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 flashing, and is, for example, a xenon lamp. The light source 51 is arranged near the center of the irradiation port 110 in the lateral 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 a part of the light emitted by the light source 51 toward the irradiation port 110. The reflecting portion 52 has a concave space 521 in which the irradiation port 110 side is open, and a light source 51 is arranged in the concave space 521. The concave curved surface forming the concave space 521 in the reflecting portion 52 is a reflecting surface.

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

The temperature detection unit 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 lateral direction of the irradiation port 110. Further, 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, before and after light irradiation, it is desired to detect the temperature of the light receiving region on the skin S. The light receiving region is a region of the skin S facing the irradiation port 110, and is a region where the treatment is performed. That is, if the temperature detection unit is arranged in the irradiation port 110, the temperature of the light receiving region can be reliably detected, but in that case, the temperature detection unit blocks the 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 the 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 Pelche element. The cooling unit 80 is arranged around the irradiation port 110. Specifically, the cooling unit 80 is arranged at a position where one of the pair of temperature sensors 71 arranged in the lateral direction of the irradiation port 110 sandwiches the temperature sensor 71 together with the irradiation port 110. That is, the irradiation port 110 and the cooling unit 80 are lined up in the lateral direction of the irradiation port 110. The cooling unit 80 has a long rectangular shape in a 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 with each other. As a result, 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 edge of the irradiation port 110 in the housing 21 are brought to the skin S. Can be brought into close contact. If the outer surface of the cooling portion 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 of light can be suppressed.

Next, the control configuration of the hair suppressing device 10 will be described. FIG. 6 is a block diagram showing a control configuration of the hair suppressing 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 is 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. And the cooling unit 80 are 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 a control signal is input from the first switch element 461 when the power is turned off, the control unit 15 supplies electric power from the commercial power source to each unit. On the other hand, when the power supply button 41 is operated and a control signal is input from the first switch element 461, the control unit 15 stops the supply of electric power from the commercial power supply. The control unit 15 turns on the lighting unit 43 when the power is turned on, and turns off the lighting unit 43 when the power is turned off. Further, the control unit 15 drives the fan 31 when the power is turned on, and stops the fan 31 when the power is turned 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 turned on, and stops the cooling unit 80 when the power is turned off. That is, when the power is turned on, the skin S is cooled by the cooling unit 80. The control unit 15 monitors the temperature detected by the four temperature sensors 71 of the temperature detection unit 70 when the power is turned on, and when the detection temperature of at least one temperature sensor 71 is equal to or higher than a predetermined value, the control unit 15 monitors the temperature detected by the four temperature sensors 71. Irradiation of the light of the irradiation unit 50 is prohibited. During this prohibition period, the control unit 15 does not accept even if a light emission signal is input from the second switch element 462. In this case, the control unit 15 notifies the user that the irradiation of light is prohibited by making the lighting pattern of the lighting unit 43 different from the normal time.

On the other hand, when the detection temperature of each of the four temperature sensors 71 is less than a predetermined value, the control unit 15 permits the irradiation of the light of the irradiation unit 50. 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 easily the skin S is damaged after the light irradiation. In particular, when a portion (chin, cheek, etc.) where thick hair grows densely, such as a beard, is irradiated with light in the above-mentioned wavelength band, the skin S becomes hot and is more susceptible to damage. Therefore, the "predetermined value" is a temperature at which the skin S is not so damaged even if the skin S is irradiated with light from the irradiation unit 50. Specifically, an appropriate value is determined in advance as a predetermined value by performing various simulations, experiments, and the like. Further, the predetermined value differs depending on the irradiation Eg. For example, when the irradiation Eg ≧ 8J, if the temperature of the skin S is 25 ° C. or higher, there is a high possibility of damaging the skin S. Therefore, the predetermined value is set to 25 ° C. When considering the safety margin, the predetermined value is set to a value lower than 25 ° C. Specifically, the predetermined value is set to, for example, 15 ° C.

[Control method]
Next, a method of controlling the hair suppressing device 10 will be described. FIG. 7 is a flowchart showing a flow of a control method of the hair suppressing device 10 according to the present embodiment. This control method shows the 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 S2, the control unit 15 determines whether or not the detection temperatures of the four temperature sensors 71 have a detection temperature 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 a predetermined value, and proceeds to step S5 when the detected temperature of each of the temperature sensors 71 is less than a predetermined value. do. In step S3, the control unit 15 prohibits the irradiation of the irradiation unit 50 with light. During this prohibition period, the control unit 15 does not accept even if a light emission signal is input from the second switch element 462. That is, since the light from the irradiation unit 50 is not applied to the heated 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 in a lighting pattern different from the normal lighting pattern. As a result, 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 grasps that the current period is the prohibited period, that is, the temperature of the skin S is higher than the predetermined value. The user operates the hair suppressing device 10 so that the skin S becomes cooler to promote cooling to the skin S by the cooling unit 80, or uses the hair suppressing device 10 until the temperature of the skin S becomes equal to or lower than a predetermined value. It can be refrained or another cooling means (ice, coolant, etc.) can be applied to the skin S. After the notification, the control unit 15 proceeds to step S2.

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

In step S6, the control unit 15 determines whether or not a light emission signal has been input from the second switch element 462 during the permission period, and if no light emission signal has been input, the process proceeds to step S2 and the light emission signal. Is input, the process proceeds to step S5. Since the process proceeds to step S2 again during the permission period, if the temperature of the skin S rises from less than a predetermined value to more than a predetermined value for some reason, the prohibition period is switched.

In step S7, 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-suppressing effect.

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

According to this, when the detection temperature of the temperature detection unit 70 is equal to or higher than a predetermined value, the irradiation of the irradiation unit 50 is prohibited, so that the heated skin S is irradiated with the light from the irradiation unit 50. Can be prevented. Therefore, damage to the skin S can be prevented.

Further, the hair suppressing device 10 includes a notification unit (lighting unit 43), and the control unit 15 controls the lighting unit 43 to perform notification when the detection temperature of the temperature detection unit 70 is equal to or higher than a predetermined value. Let me.

According to this, when the detection temperature of 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 appropriate actions based on this notification.

Further, even if the detection temperature of the temperature detection unit 70 is equal to or higher than a predetermined value, but the irradiation of the irradiation unit 50 is not prohibited, that is, even if there is an abnormality in the prohibition process, the user is notified of the skin. It can be recognized that the temperature of S is equal to or higher than a predetermined value. As a result, the user can restrain the operation of the light emitting button 42.

Further, the hair suppressing device 10 is provided around a light emitting region (irradiation port 110) in which the flashlight is emitted in the irradiation unit 50, and includes a cooling unit 80 for cooling the skin S.

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

Further, the temperature detection unit 70 is arranged 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 temperatureed without blocking the light emitted from the irradiation port 110. It can be detected by the detection unit 70.

Further, 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, it is possible to detect the temperature of the skin S with a simple structure.

[Modification example]
The configuration of the hair suppressing device 10 is not limited to the configuration described in the above embodiment. Therefore, a modified example of the hair suppressing device will be described below, focusing on the difference from the above embodiment. In the following description, the same parts as those in the above embodiment may be designated by the same reference numerals and the description thereof may be omitted.

(Modification example 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 this modification 1, a case where the temperature detection unit and the cooling unit are movable will be described.

FIG. 8 is a plan view showing a schematic configuration of the head portion 30A according to the first modification. FIG. 9 is a cross-sectional view showing the internal configuration of the head portion 30A according to the first modification. FIG. 10 is a block diagram showing a control configuration of the hair suppressing 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. 6.

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

An irradiation port 110a is formed on the holding frame 86a. The holding frame 86a slides along the lateral direction of the irradiation port 110a while maintaining the relative positional relationship between the four temperature sensors 71a of the temperature detecting 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 sliding 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.

In FIGS. 8 and 9, the case where the four temperature sensors 71a and the cooling unit 80a are in the first positions is shown by a solid line. Further, the case where the four temperature sensors 71a and the cooling unit 80a are in the second positions is shown by a broken line. Note that in FIGS. 8 and 9, the holding frame 86a at the second position is not shown.

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

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

As shown in FIG. 10, the drive source 87a of the slide unit 85a 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 permitted period, and installs the four temperature sensors 71a and the cooling unit 80a at the first positions. After that, when the 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 unit 15 controls the drive source 87a when the prohibition period is in effect, and installs the four temperature sensors 71a and the cooling unit 80a at the second position. Therefore, 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. Further, even if the light is irradiated from the irradiation unit 50 during the prohibition period, the cooling unit 80a blocks the light, so that the safety for the skin S can be ensured.

As described above, since the hair suppressing device 10A according to the first modification is provided with the sliding portion 85a for sliding the temperature detecting unit 70a and the cooling unit 80a, the temperature detecting unit does not have to move the hair suppressing device 10A. The 70a and the cooling unit 80a can be moved. As a result, the skin S can be efficiently cooled without bothering the user.

(Modification 2)
In the above embodiment, the case where the temperature detection unit 70 includes the contact type temperature sensor 71 is illustrated. In this modification 2, the case where the temperature detection unit includes a non-contact type temperature sensor is illustrated.

FIG. 11 is a plan view showing a schematic configuration of the head portion 30B according to the second modification. Specifically, FIG. 11 is a diagram corresponding 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 arranged near both ends of the irradiation port 110 in the longitudinal direction. The non-contact temperature sensor 71b includes a light emitting element 711b that emits infrared rays and a light receiving element 712b that receives infrared rays emitted by 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 lateral 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 rays, the temperature of the light emitting region of the skin S can be detected by the signal.

As described above, the temperature detection unit 70b according to the second modification includes the non-contact type temperature sensor 71b. Since the temperature detection unit 70b includes the contact type temperature sensor 71b, it is possible to reliably detect the temperature of the light receiving region of the skin S.

(Modification example 3)
In the above embodiment, the case where the cooling unit 80 is a thermoelectric element having a cooling function is illustrated. In this modification 3, a cooling unit that cools with a coolant will be described.

FIG. 12 is a cross-sectional view showing the internal configuration of the head portion 30C according to the modified example 3. Specifically, FIG. 12 is a diagram corresponding to FIG.

As shown in FIG. 12, the cooling unit 80c provided in the head unit 30C includes a cold insulation unit 81c and a discharge unit 82c in the housing 21. The cold insulation unit 81c is a storage that keeps the coolant C cold. Examples of the coolant C include a gel agent and the like. The cold insulation unit 81c keeps the coolant C cold 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 insulation portion 81c.

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

As described above, the cooling unit 80c according to the third modification includes a cooling unit 81c that keeps the coolant C cold, and a discharging unit 82c that discharges the coolant C in the cooling agent 81c toward the skin S.

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

The cooling unit is not limited to the above-mentioned one, and may be, for example, an air-cooled type or a water-cooled type.
