[0001] This disclosure relates to a hair care device and a hair care system. Background Technology
[0002] Previously, there were hair care devices such as hair dryers that not only dried the user's hair but also imparted ingredients effective for the user's hair. For example, Patent Document 1 discloses a technology related to hair dryers that uses ions as an effective ingredient for hair and adjusts the amount of the ingredient based not only on the user's settings but also on the usage time.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2019-58484 Summary of the Invention
[0006] Hairstyles and hair types vary from user to user. Therefore, even if the amount of ions, which are effective components for hair, is adjusted as in the hair dryer disclosed in Patent Document 1, it is conceivable that it will not be effective depending on the user's hairstyle and hair type. In other words, the hair dryer disclosed in Patent Document 1 may not produce the hair effect desired by the user that matches their hairstyle and hair type.
[0007] This disclosure provides a hair care device and system that easily achieves the hair effect desired by the user.
[0008] One aspect of this disclosure relates to a hair care device comprising: a heat application unit that applies heat to a user's hair; a component generation unit that generates components that act on the hair; and a measurement unit that measures or photographs the hair. Additionally, one aspect of this disclosure includes a control unit that controls the operation of the heat application unit and the component generation unit based on hair measurement values or hair images obtained from the measurement unit. The control unit includes a hair characteristic recognition unit, a table generation unit, and an application amount calculation unit. The hair characteristic recognition unit classifies the user's hair characteristics based on the hair measurement values or hair images. The table generation unit sets the component amount of the component generated by the component generation unit for each hair characteristic classified by the hair characteristic recognition unit. The application amount calculation unit adjusts the component amount for each user based on the overall hair characteristics classified by the hair characteristic recognition unit and the component amount set by the table generation unit. Alternatively, the application amount calculation unit calculates the component application amount provided by the component generation unit or the heat application amount provided by the heat application unit for each part of the hair classified by the hair characteristic recognition unit and the component amount set by the table generation unit.
[0009] In addition, one aspect of the hair care system disclosed herein includes the aforementioned hair care device and mobile terminal device. The hair care device has a transmitting and receiving unit, and the mobile terminal device has a terminal communication unit that transmits and receives data with the transmitting and receiving unit.
[0010] According to this disclosure, a hair care device and hair care system are provided that can easily achieve the hair effect desired by the user. Attached Figure Description

[0096] The hair care apparatus according to embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. However, sometimes unnecessary details are omitted. For example, detailed descriptions of well-known matters or repetitive descriptions of substantially the same structures may be omitted. Furthermore, the 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 of the claims.
[0097] (First Implementation)
[0098] Figure 1This is a schematic perspective view showing the structure of a hair dryer 1 as a hair care device according to the first embodiment. The hair dryer 1 includes a main body 10 that delivers warm air to the user and a handle 20 that is held by the user during use. Figure 2 This is a schematic cross-sectional view showing the structure of the blower 1 obtained by cutting along the air delivery direction, including the main body 10 and the gripping part 20 in the interior.
[0099] The main body 10 has a housing 3 with an outer wall formed by joining multiple segmented parts. An airflow path 4 is formed inside the housing 3, extending from an intake port 10a at one end along its long side to an exhaust port 10b at the other end. For example... Figure 2 As shown, the main body 10 and the handle 20 are connected by a connecting part 10c in a manner that allows rotation about the connecting shaft 10d. For example, when the hair dryer 1 is not in use, the handle 20 is folded relative to the main body 10 in a manner that is approximately parallel to the axial direction of the main body 10 extending in the airflow direction. In the handle 20, the power cord 2 is led out from the end opposite to the connecting part 10c.
[0100] First, the hair dryer 1 includes a heat-applying section 30, a component generating section 40, and a measuring section 50 (see reference). Figure 5 ), input unit 71 and display unit 73.
[0101] The heat-applying section 30 applies heat to the user's hair. In this embodiment, the heat-applying section 30 is an air supply section that generates warm air to be emitted from the user's hair. The heat-applying section 30 includes, for example, a fan 31, a motor 32, and a heating section 33. The fan 31 is disposed on the upstream side of the air supply path 4 and is driven to rotate by the motor 32. When the fan 31 rotates, an airflow is formed that flows into the air supply path 4 from the outside through the suction port 10a and is discharged to the outside through the air supply path 4 from the nozzle 10b. The heating section 33 is disposed on the downstream side of the fan 31 and heats the airflow from the fan 31. When the heating section 33 is working, the airflow formed by the fan 31 is heated and warm air is blown out from the nozzle 10b. The heating section 33 may also be a heater formed by winding a strip-shaped and corrugated plate-shaped resistive element along the inner periphery of the housing 3.
[0102] The ingredient generation unit 40 generates ingredients that act on the user's hair. Here, ingredients that act on hair refer to so-called beauty ingredients that can effectively affect at least the user's hair quality. Examples of such ingredients include agents / organic substances, negative ions, metallic microparticles, or charged microparticle water. Agents / organic substances are, for example, moisturizing ingredients (humectants), repairing ingredients (repairing agents), coating ingredients (coating agents), or conditioning ingredients (conditioning agents). Moisturizing ingredients include, for example, 1,3-butanediol, glycerin, panthenol, ceramides, hyaluronic acid, honey, or polysaccharides. Repairing ingredients include, for example, hydrolyzed collagen, hydrolyzed keratin, amino acids, hair-protecting proteins, peptides, cholesterol, cationic surfactants, or organic acids. Coating ingredients include, for example, silicone, squalane, or oily ingredients. Conditioning ingredients include, for example, cationic surfactants, amino acids, peptides, panthenol, and ceramides. Additionally, charged microparticle water consists of charged nanoscale water particles containing OH free radicals.
[0103] Figures 3A-3C This is a schematic diagram of the structure of various component generation devices that can be used as the component generation unit 40. Figure 3A This diagram illustrates the structure of a first electrostatic atomizing device 40a, an example of a spray device that uses an agent / organic substance as an active ingredient. The first electrostatic atomizing device 40a includes a sprayer 41a, a canister 41b, a pump 41c, a GND electrode 41d, a high-voltage circuit 41e, and a pump drive circuit 41f. The sprayer 41a is a discharge section configured to hold a liquid, which is the agent / organic substance. The canister 41b is used to contain an aqueous solution containing, for example, a polymer, which is the agent / organic substance. The pump 41c is provided in a piping connecting the canister 41b to the sprayer 41a, and delivers the polymer aqueous solution contained in the canister 41b to the sprayer 41a. The high-voltage circuit 41e applies a high voltage (HV) to the sprayer 41a. The pump drive circuit 41f controls the drive of the pump 41c. The high-voltage circuit 41e and the pump drive circuit 41f are controlled by an ingredient quantity control unit 84 (see below) within a control unit 80. Figure 5 Control. When a high voltage is applied between the sprayer 41a and the GND electrode 41d, corona discharge occurs, and a spray containing polymers is generated through this discharge. Furthermore, the spray device that uses an agent / organic substance as the active ingredient is not limited to an electrostatic atomizing device such as the first electrostatic atomizing device 40a, but may also be an ultrasonic atomizing device, a centrifugal pump, etc.
[0104] Figure 3BThis diagram shows the structure of a second electrostatic atomizing device 40b, an example of a component generating device that uses negative ions and metal microparticles as active ingredients. The second electrostatic atomizing device 40b includes a discharge section 42a, a GND electrode 42b, and a high-voltage circuit 42c. The high-voltage circuit 42c is controlled by a component quantity control section 84, similar to that of the first electrostatic atomizing device 40a. When a high voltage is applied between the discharge section 42a and the GND electrode 41d, for example, corona discharge occurs, and negative ions carrying a negative charge based on moisture in the air are generated through this discharge.
[0105] Figure 3C This diagram illustrates the structure of a third electrostatic atomizing device 40c, an example of a component generating apparatus that uses charged microparticle water as the active ingredient. The third electrostatic atomizing device 40c includes a discharge section 43a, a Peltier element 43b serving as a condenser section, a GND electrode 43c, and a high-voltage circuit 43d. The high-voltage circuit 43d is controlled by a component quantity control section 84, similar to that of the first electrostatic atomizing device 40a. When a high voltage is applied between the discharge section 43a and the GND electrode 43c, corona discharge occurs, and charged microparticle water based on moisture in the air is generated through this discharge.
[0106] For example, in the case where the component generation unit 40 in this embodiment is a third electrostatic atomizing device 40c, such as Figure 2 As shown, a partition plate 3a is provided inside the outer casing 3 of the main body 10 to form a branch path 10e extending parallel to the airflow path 4. Airflow passing through the heating section 33 flows in the airflow path 4, while airflow not passing through the heating section 33 flows in the branch path 10e. Furthermore, a third electrostatic atomizing device 40c is provided within the branch path 10e. Additionally, a component spray outlet 10f is provided in a portion of the main body 10, for example, on the front surface 10g facing the hair H during the drying operation. The component spray outlet 10f communicates with the branch path 10e and sprays outwards the component generated by the component generating section 40. Furthermore, the component generating section 40 can be at least one of the first electrostatic atomizing device 40a, the second electrostatic atomizing device 40b, and the third electrostatic atomizing device 40c. That is, multiple component generating sections 40 can be provided depending on the given component.
[0107] Measurement Unit 50 (Reference) Figure 5 The measurement unit 50 measures or photographs the user's hair and sends the processed information to the control unit 80. In this embodiment, the measurement unit 50 is designed to measure the user's hair. In this case, the measurement unit 50 includes a wetting detection unit 60, an illumination unit 72, and a signal processing unit 90 (see reference 60). Figure 5 ).
[0108] The wetting detection unit 60 detects parameters that can be referenced to obtain information related to the wetting of the user's hair. In this embodiment, the wetting detection unit 60 is a wetting detection sensor 60a with at least the absorption wavelength of water (1450 nm, etc.) set as the hair measurement value. Specifically, the wetting detection sensor 60a may be a photodiode. The illumination unit 72 is a component paired with the wetting detection sensor 60a, which is, for example, a photodiode, and illuminates light with at least the absorption wavelength of water. Furthermore, the signal processing unit 90 will be described together with the matters related to the control unit 80 below.
[0109] Figures 4A to 4C This is a schematic diagram illustrating the relationship between the various installation positions of the wetting detection sensor 60a and the illumination unit 72. Regarding the various installation positions of the wetting detection sensor 60a and the illumination unit 72, Figure 1 and Figure 2 The situation shown is one example; specifically, consider... Figures 4A to 4C Examples as shown are provided. The illumination unit 72 is a light-irradiating unit, and in contrast, the wetting detection sensor 60a is a light-receiving unit for receiving light reflected by the user's hair H after being irradiated by the illumination unit 72. The wetting detection sensor 60a and the illumination unit 72 are disposed on the front surface portion 10g or mounted on the nozzle portion 14 of the nozzle outlet 10b (see reference). Figure 4B , Figure 4C ).
[0110] Figure 4A This diagram relates to a first example of the installation position of the wetting detection sensor 60a and the illumination unit 72. In this first installation example, there is one wetting detection sensor 60a and one illumination unit 72. The wetting detection sensor 60a is installed on a portion of the front surface portion 10g. The illumination unit 72 is installed on a portion of the front surface portion 10g opposite to the wetting detection sensor 60a, across the nozzle 10b. In this case, since the distance between the wetting detection sensor 60a and the illumination unit 72 is greater than or equal to the opening diameter of the nozzle 10b, the incident angle and reflection angle of the light are large.
[0111] Figure 4B This figure relates to a second example of the installation position of the wetting detection sensor 60a and the illumination unit 72. In this second installation example, there is one wetting detection sensor 60a and multiple illumination units 72. The wetting detection sensor 60a is installed on the nozzle portion 14 in a manner that is approximately at the center of the nozzle outlet 10b. For example, there are four illumination units 72, which are installed on the front surface portion 10g at equal intervals. In this case, since the wetting detection sensor 60a and the illumination units 72 are somewhat far apart, the incident angle and reflection angle of the light can be ensured to be of a certain magnitude, and the amount of light irradiation can be increased.
[0112] Figure 4CThis figure relates to a third example of the installation position of the wetting detection sensor 60a and the illumination unit 72. In this third example, one wetting detection sensor 60a and one illumination unit 72 are each provided at the nozzle section 14. In this case, since the wetting detection sensor 60a and the illumination unit 72 are closer together, the incident angle and reflection angle of the light are smaller.
[0113] In this embodiment, as an example, let's assume it's based on... Figure 4B The second example shown is illustrated by including a wetting detection sensor 60a and an illumination unit 72.
[0114] Input section 71 is, for example, a button for allowing the user to input information related to the characteristics of the user's hair (hereinafter referred to as "hair characteristics"). Here, hair characteristics refer to at least one of the user's hairstyle, hair length, hair volume, and hair texture related to hair thickness or shine. Figure 1 In the example shown, the input unit 71 consists of three input buttons respectively provided on the housing 3: hair texture input 71a, hair length input 71b, and hair volume input 71c. Additionally, the input unit 71 may also include buttons for easily switching airflow, temperature, etc., according to the user's preferences.
[0115] The display unit 73 is a touch panel-type display screen installed on the housing 3, which functions as an input screen for user input or an output screen for displaying information to the user. Furthermore, the states when functioning as an input screen or an output screen will be described in detail below. Additionally, when the display unit 73 functions as an input screen, sometimes the input unit 71 is made unnecessary by having the display unit 73 perform the functions of the input unit 71.
[0116] In addition, such as Figure 2 As shown, the hair dryer 1 includes a room temperature sensor 61, a humidity sensor 62, a hair detection unit 63, and a body part detection unit 64.
[0117] The room temperature sensor 61 is used to measure the indoor temperature where the hair dryer 1 is used. The room temperature sensor 61 is located inside the housing 3. The output signal from the room temperature sensor 61 is sent to the control unit 80.
[0118] Humidity sensor 62 is used to measure the humidity in the room where the hair dryer 1 is used. Room temperature sensor 61 is disposed inside the housing 3. The output signal from humidity sensor 62 is sent to control unit 80.
[0119] The hair detection unit 63 detects whether the user has hair. The hair detection unit 63 is, for example, a laser rangefinder or a ToF (Time of Flight) camera, and is installed on a part of the front surface portion 10g. The output signal from the hair detection unit 63 is sent to the control unit 80.
[0120] The location detection unit 64 detects the area where the user's hair is heated or where the user's hair is treated with the aforementioned components. The location detection unit 64 can also be a posture detection unit (posture sensor) that detects the position or posture of the hair dryer 1 along at least one axis, or a distance measuring unit (distance sensor) that measures the distance to the user's hair or skin (face). Here, if the location detection unit 64 is a distance measuring unit, it is provided on a portion of the front surface portion 10g. On the other hand, if the location detection unit 64 is a posture detection unit, it is not limited to being provided on the front surface portion 10g, and may also be provided inside the housing 3. The output signal from the location detection unit 64 is sent to the control unit 80.
[0121] Figure 5 This is a block diagram showing the structure of the control unit 80 of the hair dryer 1. The control unit 80 controls the overall operation of the hair dryer 1, and controls the operation of the heat application unit 30 and the component generation unit 40 based at least on the hair measurement values obtained from the measurement unit 50. The control unit 80 is, for example, provided inside the housing 20a of the handle unit 20. Furthermore, the control unit 80 has a computer system, which has a processor and a memory. Moreover, the computer system functions as the control unit 80 by executing the program stored in the memory through the processor. Here, the program to be executed by the processor is pre-recorded in the memory of the computer system, but the program can also be provided on a non-transient recording medium such as a memory card, or it can be provided through an electrical communication line such as the Internet.
[0122] First, the control unit 80 includes a hair characteristic recognition unit 81, a table generation unit 82, an amount calculation unit 83, a component amount control unit 84, and a heat control unit 85. The hair characteristic recognition unit 81, the table generation unit 82, the amount calculation unit 83, the component amount control unit 84, and the heat control unit 85 are modules used to determine the amount of component and heat applied based on the user's hair characteristics.
[0123] The hair characteristic recognition unit 81 classifies the user's hair characteristics based on the hair measurement values obtained from the measurement unit 50.
[0124] The table generation unit 82 sets the component amounts of the components generated by the component generation unit 40 and the heat applied from the heat application unit 30, and manages these settings as a table. In the table generation unit 82, the component amounts and heat are set for each hair characteristic classified by the hair characteristic recognition unit 81.
[0125] The amount of component applied by the component generation unit 40 to the hair or the amount of heat applied by the heat application unit 30 to the hair, is calculated based on the component amount or heat amount set by the table generation unit 82. In this embodiment, the amount of component applied by the component generation unit 83 can perform the following two calculations. First, the amount of component applied by the component generation unit 83 is calculated based on the overall hair characteristics of the hair classified by the hair characteristic recognition unit 81 and the component amount set by the table generation unit 82, according to the user. Second, the amount of component applied by the component generation unit 83 is calculated based on the hair characteristics of each part of the hair classified by the hair characteristic recognition unit 81 and the component amount set by the table generation unit 82, according to the part of the hair.
[0126] The component quantity control unit 84 controls the operation of the component generation unit 40 based on the component assignment amount sent from the assignment amount calculation unit 83, that is, controls the component quantity of the component generated by the component generation unit 40.
[0127] The heat control unit 85 controls the operation of the heat application unit 30 based on the heat application amount sent from the application amount calculation unit 83, that is, controls the heat applied from the heat application unit 30.
[0128] In addition, the control unit 80 includes a wetting calculation unit 86 and a drying estimation calculation unit 87. The wetting calculation unit 86 and the drying estimation calculation unit 87 are modules used to reflect the dryness of the user's hair in terms of component application amount and heat application amount.
[0129] The wetting calculation unit 86 calculates wetting information related to the wetting of the user's hair based on the hair measurement values obtained from the measurement unit 50. Here, for example, if the wetting detection unit 60 in the measurement unit 50 is a wetting detection sensor 60a, the wetting information is the absorbance calculated based on the signal intensity from the wetting detection sensor 60a.
[0130] The dryness estimation calculation unit 87 estimates the dryness of the user's hair based on the wetting information calculated by the wetting calculation unit 86. When the wetting information is absorbance, the dryness estimation calculation unit 87 estimates the dryness based on changes in absorbance. In the dryness estimation calculation unit 87, changes in absorbance are considered, for example, by appropriately referencing the cumulative time of applying ingredients and heat to the hair (time subtraction), the cumulative time of the hair being in a floating state (time addition), or the cumulative time of applying ingredients and heat to the skin (face) (time addition). The dryness estimated by the dryness estimation calculation unit 87 is reflected by the application amount calculation unit 83 to the ingredient application amount in the ingredient amount control unit 84 or the heat application amount in the heat control unit 85. In other words, the ingredient application amount or heat application amount is corrected according to the dryness reflecting various cumulative times.
[0131] In addition, the control unit 80 includes a location calculation unit 91, an initial position determination unit 92, and an accumulation calculation unit 88. The location calculation unit 91, the initial position determination unit 92, and the accumulation calculation unit 88 are modules used to determine the part of the user's hair that has been given components and heat.
[0132] The part calculation unit 91 estimates the part of hair or skin that is given heat from the heat application unit 30 or components from the component generation unit 40 based on the information detected by the part detection unit 64 and the initial position determined by the initial position determination unit 92.
[0133] The initial position determination unit 92 determines the initial position of the blower 1 and sends it to the position calculation unit 91.
[0134] The cumulative calculation unit 88 calculates the cumulative heat applied and accumulated by the heat application unit 30 to the hair or the cumulative component amount applied and accumulated by the component generation unit 40 to the hair for each part detected by the part detection unit 64. In this case, the heat control unit 85 adjusts the heat of the heat application unit 30 based on the cumulative heat calculated by the cumulative calculation unit 88. Specifically, the heat control unit 85 uses data related to the cumulative heat calculated by the cumulative calculation unit 88 to correct the amount of heat applied and controls the operation of the heat application unit 30. On the other hand, the component amount control unit 84 adjusts the component amount of the component generation unit 40 based on the cumulative component amount calculated by the cumulative calculation unit 88. Specifically, the component amount control unit 84 uses data related to the cumulative component amount calculated by the cumulative calculation unit 88 to correct the amount of component applied and controls the operation of the component generation unit 40.
[0135] Furthermore, the control unit 80 is electrically connected to the signal processing unit 90 included in the measurement unit 50. The signal processing unit 90 controls the illumination from the illumination unit 72, processes the output of the wetness detection unit 60 (which serves as a wetness detection sensor 60a), and sends it as a signal strength to the wetness calculation unit 86. Alternatively, the signal processing unit 90 can also send the output of the wetness detection unit 60 as a signal strength to the hair characteristic recognition unit 81. In this case, the hair characteristic recognition unit 81 can classify the user's hair characteristics based on the signal strength sent from the signal processing unit 90.
[0136] In addition, such as Figure 2 As shown, the hair dryer 1 includes a power switch 76. The power switch 76 is, for example, located in the housing 20a of the handle 20. When the user operates the power switch 76 to turn on the power, power is supplied to various parts of the hair dryer 1 via the power cord 2 extending from the end of the handle 20. Furthermore, the power switch 76 can also be used to switch between warm and cold air, and to adjust the airflow, as performed by the heat-applying unit 30.
[0137] Furthermore, the hair dryer 1 may also include a transmitting / receiving unit 74 and a storage unit 75.
[0138] The transmitting / receiving unit 74 transmits signals to or receives signals from a communication device located outside the hair dryer 1, according to instructions from the control unit 80. Here, the external communication device could be, for example, a... Figure 2 The mobile terminal device 100 is shown as described. The mobile terminal device 100 includes a terminal display unit 101, a terminal camera unit 102, and a terminal communication unit 103. The terminal display unit 101 is a touch panel-type screen that displays image 101a. The terminal display unit 101 is an output screen for displaying information to the user, and also an input screen for the user to instruct or input information by touch. The terminal communication unit 103 performs transmission and reception at least between the transmitting and receiving units 74 of the hair dryer 1.
[0139] Storage unit 75 is an information storage medium that transmits and stores various types of data between itself and control unit 80. There are no particular limitations on the type of information storage medium.
[0140] Next, the operation of hair dryer 1 will be explained.
[0141] As a basic operation of the hair dryer 1, when the user holds the handle 20 and operates the power switch 76 to turn on the power, the heating unit 30 operates. Specifically, the motor 32 is driven by power supply to rotate the fan 31, thereby drawing air into the airflow path 4 from the suction port 10a. Furthermore, the heating unit 33 heats up, thereby heating the air drawn from the fan 31. The heated air becomes warm air and is ejected from the nozzle 10b. Additionally, the user appropriately operates the input unit 71, thereby causing the hair dryer 1 to cause the ingredient generating unit 40 to generate ingredients effective for hair, and ejecting these ingredients from the ingredient spray nozzle 10f.
[0142] Furthermore, the hair dryer 1 automatically optimizes the amount of ingredients applied to the hair based on the user's hair characteristics. The optimization of this ingredient application amount will be explained in detail below.
[0143] First, an example of the assumed hair characteristics in this embodiment will be explained.
[0144] Figures 6A to 6C This is a schematic diagram of hair H, illustrating the case where the hair characteristic of user U is the length of hair H. Figure 6A This shows the length H of hair when it is short. Short hair, for example, refers to hair length where the ends do not reach below the chin. Figure 6B This shows the hair length H when it is of medium length. Medium length, for example, means the hair ends are located in the range from the shoulder to the collarbone. Figure 6CThis shows the length of user U's hair H when it is long hair. Long hair, for example, refers to the length where the ends of the hair extend beyond the collarbone.
[0145] Figures 7A to 7D This is a schematic diagram of the hair H of user U, assuming the hair characteristics are a hairstyle. Figure 7A The image shows hair H when the hairstyle is long and straight. Figure 7B The image shows hair H when the hairstyle is short and straight. Figure 7C The image shows hair H with a permed hairstyle at the ends. Figure 7D The image shows hair H when the hairstyle is a full perm.
[0146] Figures 8A to 8C This is a schematic diagram of hair H, illustrating the hair characteristics of user U when the amount of hair H is quantified. Figure 8A This shows the amount of hair H when there is a large amount of hair H. Figure 8B This shows the amount of hair H under normal conditions. Figure 8C This shows the amount of hair H when it is low.
[0147] Figure 9A and Figure 9B This is a schematic diagram of hair H, illustrating the thickness of hair H in the case of user U's hair characteristics. Figure 9A This shows the hair H when its thickness is fine. When hair H is fine, its stiffness is generally soft. Figure 9B This shows the hair H when its thickness is coarse. When hair H is coarse, its hardness is generally also high.
[0148] Figure 10A and Figure 9B This is a schematic diagram of hair H, illustrating the case where the hair characteristic of user U is the shine of hair H. Figure 10A This shows hair H with a high degree of shine. Hair H with a high degree of shine typically indicates less damage. Figure 10B This shows hair H with less shine. Hair H with less shine usually indicates more damage.
[0149] Figures 11A to 11D This is a schematic diagram illustrating the first example of a judgment item used when determining the level of hair quantity H. The judgment item in this first example is the parting angle θ of hair H. B . Figure 11A Showing angle θ B For example, the hair H in the case of 120°. Figure 11B Showing angle θ B For example, the hair H in the case of 128°. Figure 11C Showing angle θB For example, the hair H in the case of 135°. Figure 11D Showing angle θ B For example, the hair H at a 145° angle. If... Figures 11A to 11D Comparing the hair H shown in each figure with each other, then regarding the angle θ B The narrowest Figure 11A The hair shown, H, has a clear parting, indicating a large quantity. Regarding the angle θ... B Moderate Figure 11B and Figure 11C The hairs H shown can be classified as having a normal quantity. Regarding the angle θ... B Widest Figure 11D The hair H shown is sparse because the parting is not clear.
[0150] Figures 12A-12C This is a schematic diagram illustrating a second example of the determination criteria used when judging the level of hair quantity H. The determination criterion in this second example is the overall width W of hair quantity H. h Width W of the face f The ratio. Here, let W be the width of the face. f For example, fix it at 15cm. Figure 12A Showing the overall width W h Hair H is measured at a length of 17cm. In this case, the ratio is 1.13. Figure 12B Showing the overall width W h The hair length (H) is 20cm. In this case, the ratio is 1.33. Figure 12C Showing the overall width W h The hair length (H) is 25cm. In this case, the ratio is 1.66. If... Figures 12A-12C Comparing the hair H shown in each figure with each other, the one with the smallest ratio... Figure 12A The hair H shown can be determined to be sparse. Regarding the ratio, it is moderate. Figure 12B The hair H shown can be judged to be of average quantity. Regarding the highest ratio... Figure 12C The hair H shown can be identified as abundant.
[0151] The hair characteristic recognition unit 81 can, for example, determine the hair characteristics by using the wetting detection unit 60 in the measuring unit 50. Figures 6A to 12C The various levels shown in the example are used to categorize the hair characteristics of user U.
[0152] Next, an example of the component amount set by the table generation unit 82 for each hair characteristic classified by the hair characteristic recognition unit 81 will be explained.
[0153] Figures 13A-13CIt is a chart showing an example of the component amounts set for each user's hair characteristics, that is, the hair characteristics set in relation to the user's overall hair.
[0154] Figure 13A This is a chart related to the amount of hair characteristic. For example, consider the case where the active ingredient (beauty ingredient) is charged microparticle water. First, the user selects the amount of hair characteristic to be used via the hair volume input unit 71c. The control unit 80, for example, via the table generation unit 82, causes the measurement unit 50 to perform the measurement required to determine the amount of the user's hair. Then, the hair characteristic recognition unit 81 receives a signal from the signal processing unit 90 and classifies the current amount of the user's hair. Here, if the hair characteristic recognition unit 81 determines that the amount of hair is normal, the table generation unit 82 may remain unchanged and be set to the default component amount. If the hair characteristic recognition unit 81 determines that the amount of hair is high, the table generation unit 82 may increase the component amount compared to the default. If the hair characteristic recognition unit 81 determines that the amount of hair is low, the table generation unit 82 may decrease the component amount compared to the default.
[0155] On the other hand, when the active ingredient is set to negative ions or an agent / organic substance, the ingredient amount is adjusted using the same considerations. If the active ingredient is set to negative ions, the surface generating section 82 can maintain the default ingredient amount if the amount of hair is normal. If the amount of hair is high, the surface generating section 82 can reduce the ingredient amount compared to the default. If the amount of hair is low, the surface generating section 82 can increase the ingredient amount compared to the default. Furthermore, if the active ingredient is set to an agent / organic substance, the surface generating section 82 can omit the ingredient if the amount of hair is normal. If the amount of hair is high, the surface generating section 82 can increase the ingredient amount compared to the default. If the amount of hair is low, the surface generating section 82 can decrease the ingredient amount compared to the default.
[0156] Figure 13BThis is a chart related to hair characteristics, specifically hair hardness (thickness). For example, consider the case where the active ingredient is charged microparticle water. First, the user selects hair hardness as the desired hair characteristic via the hair quality input unit 71a. The control unit 80, for example, uses the table generation unit 82 to cause the measurement unit 50 to perform the measurement required to determine the user's hair hardness. Then, the hair characteristic recognition unit 81 receives a signal from the signal processing unit 90 and classifies the current hair hardness of the user. Here, if the hair characteristic recognition unit 81 determines that the hair hardness or thickness is normal, the table generation unit 82 may remain unchanged and be set to the default ingredient amount. If the hair characteristic recognition unit 81 determines that the hair hardness is hard or the hair thickness is thick, the table generation unit 82 may increase the ingredient amount compared to the default. If the hair characteristic recognition unit 81 determines that the hair hardness is soft or the hair thickness is fine, the table generation unit 82 may decrease the ingredient amount compared to the default.
[0157] On the other hand, when the active ingredient is set to negative ions or an agent / organic substance, the ingredient amount is adjusted in the same way. If the active ingredient is negative ions, the surface generating section 82 can maintain the default ingredient amount if the hair hardness or thickness is normal. If the hair hardness or thickness is coarse, the surface generating section 82 can reduce the ingredient amount compared to the default. If the hair hardness or thickness is fine, the surface generating section 82 can increase the ingredient amount compared to the default. Furthermore, if the active ingredient is an agent / organic substance, the surface generating section 82 can omit the ingredient if the hair hardness or thickness is normal. If the hair hardness or thickness is coarse, the surface generating section 82 can further impart moisturizing ingredients. If the hair hardness is soft or thickness is fine, the surface generating section 82 can further impart coating ingredients.
[0158] Figure 13CThis is a graph showing the relationship between hair characteristics and hair damage (shine). For example, consider the case where the active ingredient is charged microparticle water. First, the user selects the hair characteristic as "damaged hair" via the hair quality input unit 71a. The control unit 80, for example, via the table generation unit 82, causes the measurement unit 50 to perform the measurement required to determine the user's hair damage. Then, the hair characteristic recognition unit 81 receives a signal from the signal processing unit 90 and classifies the current hair damage of the user. Here, if the hair characteristic recognition unit 81 determines that the hair damage or shine is normal, the table generation unit 82 may remain unchanged and be set to the default ingredient amount. If the hair characteristic recognition unit 81 determines that the hair damage is high or the shine is low, the table generation unit 82 may increase the ingredient amount compared to the default. If the hair characteristic recognition unit 81 determines that the hair damage is low or the shine is high, the table generation unit 82 may decrease the ingredient amount compared to the default.
[0159] On the other hand, when the active ingredient is set to negative ions or an agent / organic substance, the ingredient amount is adjusted using the same considerations. If the active ingredient is set to negative ions, the surface generation section 82 can maintain the default ingredient amount if the hair damage or shine is normal. If the hair damage is high or the shine is low, the surface generation section 82 can reduce the ingredient amount compared to the default. If the hair damage is low or the shine is high, the surface generation section 82 can increase the ingredient amount compared to the default. Furthermore, if the active ingredient is set to an agent / organic substance, the surface generation section 82 can maintain the default ingredients such as repair ingredients or coating ingredients if the hair damage or shine is normal. If the hair damage is high or the shine is low, the surface generation section 82 can increase the default ingredient amount. If the hair damage is low or the shine is high, the surface generation section 82 can decrease the default ingredient amount.
[0160] Figure 14A and Figure 14B This is a chart showing examples of component amounts set according to the location and condition of the user's hair. Here, as an example, the user's hair is categorized into three parts: the root, the middle, and the ends. Furthermore, hair condition refers to the hair texture as detected by the location of the hair; specifically, it includes hair damage, alkaline hair, cuticle peeling, increased water absorption when the hair is wet, and decreased water retention when the hair is dry.
[0161] Figure 14AThis chart relates to various hair conditions, including damaged hair, alkaline hair, hair with peeling cuticle, and increased water absorption when wet. First, assuming the hair dryer 1 can provide a repair agent as an ingredient to repair the user's damaged hair, and the control unit 80 determines that the hair is heavily damaged. In this case, the control unit 80 controls the ingredient generation unit 40 to apply a smaller amount of repair agent than the default amount to the roots of the hair. Additionally, the control unit 80 controls the ingredient generation unit 40 to apply the repair agent to the middle of the hair without changing the default amount. Furthermore, the control unit 80 controls the ingredient generation unit 40 to apply a larger amount of repair agent than the default amount to the ends of the hair.
[0162] Furthermore, assuming the hair dryer 1 can impart charged microparticle water as an ingredient for repairing the user's alkaline hair, and the control unit 80 determines that the user's hair is alkaline, the control unit 80 controls the ingredient generating unit 40 to apply a smaller amount of charged microparticle water to the roots of the hair than the default amount. Additionally, the control unit 80 controls the ingredient generating unit 40 to apply charged microparticle water to the middle of the hair without changing the default amount. Finally, the control unit 80 controls the ingredient generating unit 40 to apply a larger amount of charged microparticle water to the ends of the hair than the default amount.
[0163] Furthermore, assuming the hair dryer 1 can impart lead microparticles (metal microparticles) as a component for repairing cuticle peeling in the user's hair, and the control unit 80 determines that cuticle peeling has occurred, the control unit 80 controls the component generation unit 40 to apply a smaller amount of lead microparticles than the default component amount to the roots of the hair. Additionally, the control unit 80 controls the component generation unit 40 to apply lead microparticles to the middle of the hair without changing the default component amount. Finally, the control unit 80 controls the component generation unit 40 to apply a larger amount of lead microparticles than the default component amount to the ends of the hair.
[0164] Furthermore, assuming the hair dryer 1 can impart charged microparticle water and the control unit 80 determines that the user's hair absorbs more water when wet, the control unit 80 controls the component generation unit 40 to impart charged microparticle water to the roots of the hair without changing the default component amount. Additionally, the control unit 80 controls the component generation unit 40 to impart a larger amount of charged microparticle water to the middle and ends of the hair than the default component amount.
[0165] Figure 14BThis chart relates to the decrease in moisture retention of hair after drying. First, assuming the hair dryer 1 can apply a conditioning agent to replenish the decreased moisture retention, and the control unit 80 determines that the moisture retention of the hair has decreased after drying. In this case, the control unit 80 controls the ingredient generation unit 40 to apply a smaller amount of conditioning agent than the default amount to the roots of the hair. Furthermore, the control unit 80 controls the ingredient generation unit 40 to apply the conditioning agent to the middle of the hair without changing the default amount. Finally, the control unit 80 controls the ingredient generation unit 40 to apply a larger amount of conditioning agent than the default amount to the ends of the hair.
[0166] Furthermore, assuming that the hair dryer 1 can impart moisturizing ingredients to replenish the decreased moisture retention, and the control unit 80 determines that the moisture retention of the hair has decreased after drying, the control unit 80 controls the ingredient generation unit 40 to apply moisturizing ingredients to the roots of the hair without changing the default ingredient amount. Additionally, the control unit 80 controls the ingredient generation unit 40 to apply a larger amount of moisturizing ingredients than the default amount to the middle and ends of the hair.
[0167] Furthermore, assuming that the hair dryer 1 can apply a coating agent to replenish the decreased moisture retention, and the control unit 80 determines that the moisture retention of the hair has decreased after drying, the control unit 80 controls the ingredient generation unit 40 to apply a smaller amount of coating agent than the default amount to the roots and middle of the hair. Additionally, the control unit 80 controls the ingredient generation unit 40 to apply the coating agent to the ends of the hair without changing the default amount of ingredient.
[0168] Furthermore, assuming that the hair dryer 1 can impart charged microparticle water as a component to replenish the decreased moisture retention, and the control unit 80 determines that the moisture retention of the hair has decreased after drying, the control unit 80 controls the component generation unit 40 to impart charged microparticle water to the roots of the hair without changing the default component amount. Additionally, the control unit 80 controls the component generation unit 40 to impart a larger amount of charged microparticle water than the default component amount to the middle and ends of the hair.
[0169] Next, an example will be given of setting the drying time as a time series, which is related to the components supplied by the component generation section 40 or the heat supplied by the heat supply section 30.
[0170] Figure 15This is a time-series diagram illustrating an example of the relationship between the amount of cosmetic applied and the detection of hair on the user's skin. The upper diagram shows the amount of cosmetic applied (mg) relative to drying time (s). Hereafter, the cosmetic will be referred to as an agent / organic substance, as a general term for the various ingredients illustrated above. Here, as an example, the amount applied when applying the cosmetic is fixed at 4 mg. The lower diagram shows the presence or absence of hair detection relative to drying time (s). Figure 15 In the diagram, the drying time corresponds to the horizontal axis of the upper and lower graphs. The control unit 80 determines the presence or absence of hair, for example, based on the output signal of the hair detection unit 63. Here, the presence of hair means that the airflow from the hair dryer 1 comes into contact with the user's hair. Conversely, the absence of hair means that the airflow from the hair dryer 1 does not come into contact with the user's hair. That is, as... Figure 15 As shown, the control unit 80 can also cause the ingredient generation unit 40 to apply the cosmetic only if it determines that hair is present.
[0171] Figure 16 This is a time-series diagram illustrating an example of the relationship between the amount of charged microparticles administered and the location detection of the user's hair. The upper graph shows the amount of charged microparticles administered (mg) relative to drying time (s). The lower graph shows the location detection of the hair relative to drying time (s). Figure 16 In the diagram, the drying time corresponds to the horizontal axis of the upper and lower graphs. The control unit 80 determines, for example, the location contacted by the charged microparticle water emitted from the blower 1 based on the output signal of the location detection unit 64. Here, as... Figure 16 As shown, during periods when the control unit 80 determines that no hair is present, it prevents the component generating unit 40 from generating charged microparticle water. On the other hand, during the period when the control unit 80 blows air onto the roots of the hair to dry them, it causes the component generating unit 40 to apply, for example, 2 mg of charged microparticle water containing charged microparticles. Furthermore, during the period when the control unit 80 blows air onto the middle of the hair to dry them, it causes the component generating unit 40 to apply, for example, 3 mg of charged microparticle water containing charged microparticles. And, during the period when the control unit 80 blows air onto the ends of the hair to dry them, it causes the component generating unit 40 to apply, for example, 4 mg of charged microparticle water containing charged microparticles. In other words, the control unit 80 can reduce the amount of charged microparticle water applied to the roots of the hair and increase the amount applied to the ends of the hair.
[0172] Figure 17 This is a time-series diagram illustrating an example of the relationship between the amount of cosmetic applied and the location of hair follicle detection on a user. The upper graph shows the amount of cosmetic applied (mg) relative to drying time (s). The lower graph shows the location of hair follicle detection relative to drying time (s). Figure 17In the diagram, the drying time corresponds to the horizontal axis of the upper and lower graphs. The control unit 80, for example, determines the area contacted by the cosmetic dispensed from the hair dryer 1 based on the output signal of the area detection unit 64. Here, as... Figure 17 As shown, when the control unit 80 determines that no hair is present, it prevents the ingredient generating unit 40 from generating cosmetics. On the other hand, when the control unit 80 dries the roots of the hair by blowing air, it applies, for example, 2 mg of cosmetics to the ingredient generating unit 40. Furthermore, when the control unit 80 dries the middle of the hair by blowing air, it applies, for example, 3 mg of cosmetics to the ingredient generating unit 40. And, when the control unit 80 dries the ends of the hair by blowing air, it applies, for example, 4 mg of cosmetics to the ingredient generating unit 40. In other words, the control unit 80 can reduce the amount of cosmetics applied to the roots of the hair and increase the amount applied to the ends of the hair.
[0173] Figure 18 This is a time-series diagram illustrating an example of the relationship between the dosage of two cosmetics, A and B, and the location of hair samples taken from a user. The top diagram shows the dosage (mg) of cosmetic A relative to drying time (s). The middle diagram shows the dosage (mg) of cosmetic B relative to drying time (s). Cosmetics A and B are different ingredients. Cosmetics A is an ingredient that works particularly effectively on the hair roots. Cosmetics B is an ingredient that works particularly effectively on the hair tips. The bottom diagram shows the location of hair samples taken relative to drying time (s). Figure 18 In the diagram, the drying time corresponds to the horizontal axis of the upper, middle, and lower graphs. The control unit 80, for example, determines the area contacted by cosmetic A or cosmetic B emitted from the blower 1 based on the output signal of the area detection unit 64. Here, as... Figure 18 As shown, during periods when hair is determined to be absent, the control unit 80 prevents the ingredient generating unit 40 from generating either cosmetic A or cosmetic B. On the other hand, during the period of drying the hair roots by blowing air, the control unit 80 applies only, for example, 4 mg of cosmetic A to the ingredient generating unit 40. Furthermore, during the period of drying the hair midsection by blowing air, the control unit 80 applies, for example, 2 mg of cosmetic A and 2 mg of cosmetic B to the ingredient generating unit 40. And, during the period of drying the hair ends by blowing air, the control unit 80 applies, for example, 4 mg of cosmetic B to the ingredient generating unit 40. In other words, it is also possible for the control unit 80 to specifically apply cosmetic A, which is effective for the hair roots, to the hair roots, and cosmetic B, which is effective for the hair ends, to the hair ends.
[0174] Figure 19This is a timing diagram illustrating an example of the relationship between the amount of charged microparticles applied and the detection of the permed section when the user's hairstyle is partially permed. The upper diagram shows the amount of charged microparticles applied (mg) relative to drying time (s). Here, as an example, the amount of charged microparticles applied when applying water is fixed at 4 mg. The lower diagram shows the permed or non-permed section as a result of hair detection relative to drying time (s). Figure 19 In the diagram, the drying time corresponds to the horizontal axis in the upper and lower graphs. The control unit 80, for example, determines whether the area of hair being air-blown is the permed or non-permed section based on the output signal of the wetting detection unit 60. Figure 19 As shown, the control unit 80 can also supply charged microparticle water to the component generation unit 40 only when it determines that the part of the hair being blown is not a permed part. As a result, the hair dryer 1 can prevent the straightening of the permed part caused by moisture in advance.
[0175] Figure 20 This is a time-series diagram illustrating an example of the relationship between airflow and the location detection of a user's hair. The diagram above shows airflow (m³) relative to drying time (s). 3 / s). The figure below shows the location detection of hair relative to drying time (s). Figure 20 In the diagram, the drying time corresponds to the horizontal axis of the upper and lower graphs. The control unit 80 determines, for example, the area touched by the airflow from the blower 1 based on the output signal of the area detection unit 64. Here, as... Figure 20 As shown, during the period when the control unit 80 determines that no hair is present, the heat-applying unit 30 applies, for example, 2 (m) heat. 3 The airflow is delivered at a rate of / s. On the other hand, while the control unit 80 delivers air to the roots of the hair to dry it, the heat-applying unit 30 applies an airflow of, for example, 10 (m²). 3 Airflow of 8 (m³ / s) is supplied. Additionally, during the drying process of the hair, the control unit 80 directs the heat transfer unit 30 to a flow rate of, for example, 8 (m³ / s). 3 Airflow is supplied at a rate of / s. Furthermore, during the process of supplying air to the ends of the hair to dry it, the control unit 80 causes the heat-applying unit 30 to apply an airflow of, for example, 6 (m²). 3 The airflow is supplied at a rate of / s. In other words, the control unit 80 can also increase the airflow towards the root side of the hair and decrease the airflow towards the tip side of the hair. In addition, the control unit 80 can also stop the heat supply unit 30 from supplying air during periods when it is determined that there is no hair.
[0176] Next, the input screen for allowing the user to input information and the output screen for displaying information to the user will be described. In this embodiment, a display unit 73 is provided on the outer casing 3 of the main body 10. Therefore, the input screen and the output screen can also be displayed on the display unit 73. On the other hand, if the hair dryer 1 is equipped with a transmission / reception unit 74 for sending and receiving various information with the mobile terminal device 100, the input screen and the output screen can be displayed on the terminal display unit 101 of the mobile terminal device 100 instead of the display unit 73. That is, if the hair dryer 1 is equipped with a transmission / reception unit 74, the display unit 73 may not be required. In the following description, the case where the input screen and the output screen are displayed on the terminal display unit 101 of the mobile terminal device 100 will be illustrated.
[0177] Figures 21A to 21C This is a schematic diagram showing a first example of an input screen displayed on the terminal display unit 101 (or display unit 73). Figure 21A The first input screen related to the first example is shown. The image 101a displayed in the first input screen is a simplified diagram of the user's front hairstyle, and is a segmented image obtained by dividing it in the vertical and horizontal directions. A simplified diagram of the user's back hairstyle is also displayed in the first input screen. Figure 21B The second input screen of the first example is shown. The image 101a displayed in the second input screen is a simplified diagram of the user's hairstyle from the side, and is a segmented image obtained by segmenting in the front-to-back direction. Figure 21C The third input screen of the first example is shown. In the third input screen, horizontal adjustment screens for users to change the settings of certain items are displayed in each area of the split screen shown in the first and second input screens.
[0178] Figure 22A and Figure 22B This is a schematic diagram showing a first example of an output screen displayed on the terminal display unit 101 (or display unit 73). The first example of the output screen displays various states in real time related to the period during which the hair dryer 1 dries the hair or applies ingredients to the hair. Figure 22A It is the output screen at the midpoint of the hair drying process. Figure 22B This is the output screen showing the time it takes for the hair roots to dry. The first example output screen displays items such as the part of the hair currently drying, the temperature of the drying part (the temperature of the part being blow-dried), the moisture content of the hair, and the amount of added components. In this example, the components are displayed as the amounts of charged microparticle water and negative ions. Figure 22A and Figure 22BAs shown, a simplified diagram of the hair dryer can be displayed to visually indicate the area where the hair is drying. Similarly, the amount of water and other components can be visually indicated to the user by displaying not only numerical values but also, for example, pie charts.
[0179] Figure 23 This is a schematic diagram showing a second example of the output screen displayed on the terminal display unit 101 (or display unit 73). The output screen in this second example displays various states related to the hair drying process after the hair dryer 1 has dried at least a portion of the hair or applied components to at least a portion of the hair. For example... Figure 23 As shown, based on the user's use of hair dryer 1, the amount of ingredients effective for the user's hair can also be displayed. In this example, the amounts of charged microparticle water and negative ions are displayed.
[0180] Figure 24A and Figure 24B This is a schematic diagram showing a third example of an output screen displayed on the terminal display unit 101 (or display unit 73). Similar to the second example, the third example's output screen displays various states non-real-time. Furthermore, the third example's output screen displays the composition of each part of the user's hair, and displays the hair part and the composition of each part in a manner that the user can change. In the third example's output screen, a simplified diagram of the user's hair marked with three touch areas is first displayed. The first touch area 101b corresponds to the root of the hair. The second touch area 101c corresponds to the middle part of the hair. The third touch area 101d corresponds to the tip of the hair. In addition to numerical values, the composition at the current time point is also displayed in the third example's output screen using, for example, pie charts. For example, the first pie chart 101e shows the composition of charged microparticle water. The second pie chart 101f shows the composition of negative ions. As an example, Figure 24A This shows the user selecting the middle section as the area of hair whose composition they want to change through subsequent actions of the hair dryer 1. In this case, the user can select the middle section by touching the second touch area 101c on the third output screen. As an example, Figure 24B This indicates that the user has entered a new ingredient amount when they want to change the ingredient amount through subsequent actions of the hair dryer 1. The user can set the desired ingredient amount by touching the first pie chart 101e and the second pie chart 101f on the third output screen while changing the displayed values.
[0181] Figure 25 This is a schematic diagram showing a fourth example of an output screen displayed on the terminal display unit 101 (or display unit 73). Similar to the third example, the fourth example of the output screen displays various states non-real-time. Figure 24A In the output screen of the third example shown, when any of the first touch area 101b, the second touch area 101c, and the third touch area 101d is touched, the component amount of the corresponding part is displayed. In contrast, in the output screen of the fourth example, the component amount of each part of the hair is displayed at once, and the order in which the user should apply heat or components using the hair dryer 1 is shown numerically. By moving the hair dryer 1 in the order of the numbers labeled on the first touch area 101b, the second touch area 101c, and the third touch area 101d, the user can efficiently apply the desired components.
[0182] Figure 26A and Figure 26B This is a schematic diagram showing a second example of an input screen displayed on the terminal display unit 101 (or display unit 73). The second example of the input screen corresponds to a situation where the composition applied to the user according to the location of the hair is changed. Figure 26A The first input screen of the second example is shown. The image 101a displayed in the first input screen is a simplified diagram of the user's front hairstyle, and is a segmented image divided into three parts in the vertical direction: the roots, the middle, and the ends. A simplified diagram of the user's back hairstyle is also displayed in the first input screen. Figure 26B The second input screen of the second example is shown. In the second input screen, level adjustment screens for allowing the user to change the setting of charged microparticle water are displayed in each area of the split screen shown on the first input screen. Regarding charged microparticle water, if the user does not want to change it to the component amount set by the control unit 80 but wants to change it to their desired component amount, the first input screen first displays three areas in the hair where the component amount can be changed as image 101a. Then, the user can display the second input screen and change the level by multiple areas to achieve the desired component amount of charged microparticle water.
[0183] Figure 27 It shows the use Figure 26B The second example shown is a graph illustrating the settings for changing the amount of hair component based on its location. Figure 26BIn the example shown, if the component to be changed is charged microparticle water, for instance, if the level of charged microparticle water applied to the roots of the hair was "2" before the change, the user can adjust the level to "3" using the input screen in the second example, according to their own preference. For other parts of the hair, such as the middle and ends, the user can similarly change the amount of the component related to charged microparticle water to the desired amount by changing the level. Furthermore, not only charged microparticle water, but also other components such as negative ions and agents / organic substances can have their amounts changed using the input screen in the second example.
[0184] Next, it will be explained how the control unit 80 estimates the degree of dryness of the hair when drying the user's hair.
[0185] Figure 28 This is a diagram illustrating several principles that can be used to determine whether hair is wet or dry. First, in this embodiment, the dryness of the hair is estimated by the dryness estimation calculation unit 87 based on the wetness information calculated by the wetness calculation unit 86. Furthermore, in this embodiment, specifically, the wetness detection unit 60 is a wetness detection sensor 60a, which is a photodiode. The wetness information is the absorbance calculated by the wetness calculation unit 86 based on the signal strength from the wetness detection sensor 60a. For example... Figure 28 As shown in the upper section, when the hair is wet, more light is absorbed by the hair when it is illuminated by the illumination unit 72, thus reducing the amount of reflected light received by the wetness detection sensor 60a. On the other hand, when the hair is dry, less light is absorbed by the hair when it is illuminated by the illumination unit 72, thus the amount of reflected light received by the wetness detection sensor 60a does not decrease. In other words, the dryness estimation calculation unit 87 can estimate the degree of dryness based on the change in absorbance, that is, estimate whether the hair is wet or dry.
[0186] Alternatively, as another principle, the hair bundle state can be set as wetting information, and the dryness of the hair can be calculated using machine learning. In this case, the wetting detection unit 60 is a camera or other imaging unit that captures images of the hair. The wetting calculation unit 86 is a machine learning calculation unit that determines the hair bundle state based on the hair image captured by the wetting detection unit 60. Figure 28 As shown in the middle column, when the hair is wet, the hairs stick together to form clumps. On the other hand, when the hair is dry, the hairs are separated and independent of each other. That is to say, the dryness estimation calculation unit 87 can estimate the degree of dryness based on the clump state of the hair determined by the machine learning calculation unit.
[0187] Furthermore, the temperature of the hair can also be set as moisture information, and the dryness of the hair can be calculated by the moisture calculation unit 86. In this case, the moisture detection unit 60 is a temperature sensor. The temperature sensor can also be, for example, an infrared thermometer (infrared sensor). The moisture calculation unit 86 calculates the temperature as moisture information based on the hair measurement value measured by the moisture detection unit 60. Figure 28 As shown in the lower section, when the hair is wet, when warm air is emitted from the nozzle 10b to the hair, the temperature on the surface of the hair is difficult to rise and easy to cool, so the temperature change is small. On the other hand, when the hair is dry, when warm air is emitted from the nozzle 10b to the hair, the temperature on the surface of the hair rises easily and is difficult to cool, so the temperature change is large. In other words, the drying estimation calculation unit 87 can estimate the degree of dryness based on the temperature change of the hair.
[0188] Figure 29 Is with Figure 28 Correspondingly, a chart illustrating the specific criteria for determining whether hair is in a wet or dry state is provided. Firstly, as in this embodiment, when determining based on changes in absorbance, such as... Figure 29 As shown in the upper section, hair can be judged as wet when the absorbance is 70%–30%, and as dry when the absorbance is 29%–10%. Furthermore, in cases where the determination is based on the hair's bundle state, such as… Figure 28 and Figure 29 As shown in the respective middle columns, the results can be followed according to machine learning. Furthermore, in cases where judgments are based on temperature changes, such as... Figure 29 As shown in the lower column, hair can be considered wet when the temperature gradient is gentle when it comes into contact with warm air, and dry when the gradient is steep.
[0189] Figure 30 It is a graph showing the parameters calculated in the wetting calculation unit 86 based on the signal intensity from the wetting detection sensor 60a at various absorbance levels, which are then transmitted to the drying estimation calculation unit 87 and the amount of absorption calculation unit 83.
[0190] First, assuming an absorbance of 0%, the distance from the hair dryer 1 to the point where the warm air does not reach the hair (the so-called atmospheric level where the warm air only comes into contact with the atmosphere). In this case, the parameter transmitted from the wetting calculation unit 86 to the drying estimation calculation unit 87 is information indicating that the warm air at the current time point is not helpful in drying the hair. On the other hand, the parameter transmitted from the wetting calculation unit 86 to the application amount calculation unit 83 is information used to stop the application of the component or to stop counting the application time of the component.
[0191] Furthermore, when the absorbance is between 0% and 9%, it is assumed that the warm air reaches the hair and the hair is floating in a nearly dry state. In this case, the parameter transmitted from the wetting calculation unit 86 to the drying estimation calculation unit 87 is information indicating that the warm air at the current time point does not contribute to the drying of the hair. On the other hand, the parameter transmitted from the wetting calculation unit 86 to the application amount calculation unit 83 is information used to stop the application of the component or to stop counting the application time of the component.
[0192] Furthermore, when the absorbance is between 10% and 29%, it is assumed that warm air has reached the hair and the hair is drying. In this case, the parameter transmitted from the wetting calculation unit 86 to the drying estimation calculation unit 87 is information indicating that the warm air is drying the hair at the current time point. On the other hand, the parameter transmitted from the wetting calculation unit 86 to the application amount calculation unit 83 is information for the application of components.
[0193] Furthermore, when the absorbance is between 30% and 70%, it is assumed that warm air reaches the hair but the hair remains moist. In this case, the parameter transmitted from the wetting calculation unit 86 to the drying estimation calculation unit 87 is information indicating that the warm air has dried the hair at the current time point. On the other hand, the parameter transmitted from the wetting calculation unit 86 to the application amount calculation unit 83 is information for the application of components.
[0194] Furthermore, when the absorbance is between 71% and 90%, it is assumed that the warm air reaches the skin (face) rather than the hair (skin level). In this case, the parameter transmitted from the wetting calculation unit 86 to the drying estimation calculation unit 87 is information indicating that the warm air at the current time point does not contribute to the drying of the hair. On the other hand, the parameter transmitted from the wetting calculation unit 86 to the application amount calculation unit 83 is information for the application of ingredients.
[0195] Furthermore, when the absorbance is 100%, it is assumed that the warm air reaches the hair but the hair is significantly wetted overall (the warm air almost entirely comes into contact with water). In this case, the parameter passed from the wetting calculation unit 86 to the drying estimation calculation unit 87 is information indicating that the warm air at the current time point does not contribute to the drying of the hair. On the other hand, the parameter passed from the wetting calculation unit 86 to the application amount calculation unit 83 is information used to stop the application of the component or to stop counting the application time of the component.
[0196] Next, the method for determining the end of drying based on absorbance will be explained.
[0197] Figure 31This is a flowchart illustrating the drying completion determination process using absorbance as the determination criterion. First, the control unit 80 causes the hair detection unit 63 to detect the user's hair (step S101). Next, the control unit 80 determines the presence of hair based on the detection result of the hair detection unit 63 (step S102). If the control unit 80 determines that no hair is present (step S102: "No"), it returns to step S101 and repeats the hair detection. Conversely, if the control unit 80 determines that hair is present (step S102: "Yes"), it then causes the illumination unit 72 to irradiate infrared light onto the hair (step S103). Next, the control unit 80 causes the wetting detection sensor 60a to measure the reflected light reflected by the hair as the infrared light is irradiated (step S104). Finally, the control unit 80 determines whether the reflectance measurement was successful (step S105). Here, if the control unit 80 determines that the reflectance measurement was unsuccessful (step S105: "No"), it returns to step S103 and performs a second measurement of the reflected light. On the other hand, if the control unit 80 determines that the reflectance measurement was successful (step S105: "Yes"), it then causes the drying estimation calculation unit 87 to estimate the degree of dryness (step S106). Next, the control unit 80 determines whether the reflectance determined based on the reflected light measurement result in step S104 is 80% or higher (step S107). Here, if the control unit 80 determines that the reflectance is lower than 80% (step S107: "No"), it returns to step S101 and repeats the drying process. On the other hand, if the control unit 80 determines that the reflectance is 80% or higher (step S107: "Yes"), it terminates the drying process.
[0198] Next, we will explain the point about taking into account the shape of the user's head when estimating dryness based on absorbance.
[0199] Figures 32A-32C This is a schematic diagram illustrating the degree of light reflection at the user's head, as measured by the measuring unit 50. Figure 32A This is a schematic diagram showing the use of the measuring unit 50 to measure the state of a user's hair H. In this embodiment, the measuring unit 50 includes a wetting detection sensor 60a (photodiode) as a wetting detection unit 60, and an illumination unit 72. Figure 32B This is a schematic diagram showing the measuring unit 50 measuring the top of the user's head. On the other hand, Figure 32C This is a schematic diagram showing the measuring unit 50 measuring the side of the user's head. Here, as an example, the two illumination units 72 are along the x-direction (see reference...). Figure 32C ), positioned opposite to the wetting detection sensor 60a. For example, assume that the hair dryer 1 is moved from Figure 32B Move the position shown along the x-direction to Figure 32CThe position is shown. At this time, as the hair dryer 1 moves from one side of the top of the head to one side of the side of the head, the distance y from the hair H to the wetness detection sensor 60a increases. In addition, the light emitted from the two illumination units 72 diverges with reflection angles θ1 and θ2 relative to the tangent on the illuminated hair H. That is, as the measurement position moves from one side of the top of the head to one side of the side of the head, the degree of light reflection changes, and the reflectivity decreases.
[0200] Figure 33A and Figure 33B It is a graph showing the change in reflectivity of the user's head when measured, as shown in Figure 32. Figure 33A This is a graph showing the reflectivity (%) of the image reflected from the user's head relative to the distance y (mm) from the user's head (hair H) to the wetting detection sensor 60a. As such, the reflectivity decreases as the user's head moves further away from the wetting detection sensor 60a. Figure 33B This is a graph showing the reflectance (%) reflected from the head during the drying process relative to the drying time (s). During the drying process, the reflectance changes slightly due to the small movement of the blower 1, but a certain tendency for the reflectance to increase is also visible as the drying time progresses.
[0201] In this way, the drying estimation calculation unit 87 can also be considered to use... Figures 32A to 33B The variation in reflectivity is explained, and the degree of reflection of light from the illumination unit 72 is made equalized according to the curvature of the user's head, thereby estimating the dryness.
[0202] Next, the adjustment of temperature and composition of each part of the object that the warm air comes into contact with will be explained.
[0203] Figure 34A and Figure 34B It is a diagram used to illustrate the adjustment of temperature and composition of each part of an object that is exposed to warm air. Figure 34A This is a summary diagram illustrating the object. Here, the assumed object refers to the atmosphere, hair, and skin (face). Figure 34A Of the three hair dryers 1 shown, the first hair dryer 1a is positioned a distance from the hair H so that the warm air does not reach the hair, thus the warm air can be considered to be directed towards the atmosphere. The second hair dryer 1b targets the hair as the area contacted by the warm air. The third hair dryer 1c targets the skin F as the area contacted by the warm air.
[0204] Figure 34B This is a diagram illustrating an example of the conditions used to determine which part of an object is, the temperature settings for each part of the object, and the adjustments to the components.
[0205] First, for example, if it is determined that the wetting detection sensor 60a detects no data regardless of whether the illumination unit 72 is illuminating, the wetting calculation unit 86 can determine that the target area is equivalent to the atmosphere (atmospheric level). In this case, the heat control unit 85 does not change the temperature of the heat application unit 30. If the component generation unit 40 generates charged microparticle water or negative ions, the component quantity control unit 84 does not change the component quantity of the component generation unit 40. If the component generation unit 40 generates an agent or polymer, the component quantity control unit 84 stops the component application unit 40 from applying components.
[0206] Furthermore, for example, if it is determined that the object part has moved due to wind based on the measurement performed by the wetting detection sensor 60a, the wetting calculation unit 86 can determine that the object part is hair. In this case, the heat control unit 85 does not change the temperature of the heat application unit 30. If the component generation unit 40 generates charged microparticle water or negative ions, the component amount control unit 84 does not change the component amount of the component generation unit 40. If the component generation unit 40 generates an agent or polymer, the component amount control unit 84 applies the component for hair to the component generation unit 40.
[0207] Furthermore, for example, if it is determined, based on the measurement performed by the wetting detection sensor 60a, that the target portion does not move due to wind, the wetting calculation unit 86 can determine that the target portion is skin. In this case, the heat control unit 85 causes the heat application unit 30 to decrease in temperature. If the ingredient generation unit 40 generates charged microparticle water, the ingredient quantity control unit 84 does not change the ingredient quantity of the ingredient generation unit 40. If the ingredient generation unit 40 generates negative ions, the ingredient quantity control unit 84 stops the ingredient application unit 40 from applying ingredients. If the ingredient generation unit 40 generates an agent or polymer, the ingredient quantity control unit 84 applies skin-friendly ingredients to the ingredient generation unit 40.
[0208] Figure 35 This is a time-series diagram illustrating an example of the relationship between the dosage of two cosmetics, A and B, and site detection on the target area. The top diagram shows the dosage (mg) of cosmetic A relative to drying time (s). The middle diagram shows the dosage (mg) of cosmetic B relative to drying time (s). Cosmetics A and B are different ingredients. Cosmetics A is an ingredient that works particularly effectively on hair. Cosmetics B is an ingredient that works particularly effectively on skin. The bottom diagram shows site detection on the target area relative to drying time (s). Figure 35In the diagram, the drying time corresponds to the horizontal axis of the upper, middle, and lower graphs. Here, when the control unit 80 determines that the target area is equivalent to the atmosphere, it prevents the ingredient generating unit 40 from generating either cosmetic A or cosmetic B. On the other hand, when the control unit 80 determines that the target area is hair, it causes the ingredient generating unit 40 to apply only, for example, 4 mg of cosmetic A. Furthermore, when the control unit 80 determines that the target area is skin, it causes the ingredient generating unit 40 to apply only, for example, 4 mg of cosmetic B. In other words, as... Figure 35 As shown, the control unit 80 can also apply a cosmetic A that is effective for the hair to the hair, and a cosmetic B that is effective for the skin to the skin.
[0209] Next, an example will be given of setting the drying time as a time series, which is related to the degree of dryness of the hair and the components imparted by the component generation section 40 or the heat imparted by the heat imparting section 30.
[0210] Figure 36 This is a time-series graph illustrating an example of the relationship between the amount of charged microparticles applied and the degree of dryness of hair. The upper graph shows the amount of charged microparticles applied (mg) relative to drying time (s). The lower graph shows the degree of dryness (%) relative to drying time (s). Figure 36 In the diagram, the drying time corresponds to the horizontal axis of the upper and lower graphs. The control unit 80 can also adjust the amount of charged microparticle water applied based on the dryness of the hair. Specifically, the control unit 80 can increase the amount of charged microparticle water applied when the hair is wet, i.e., when the dryness is low, and decrease the amount of charged microparticle water applied when the hair is dry, i.e., when the dryness is high.
[0211] Figure 37 This is a time-series graph illustrating an example of the relationship between the amount of cosmetic applied and the degree of dryness of hair. The upper graph shows the amount of cosmetic applied (mg) relative to drying time (s). The lower graph shows the degree of dryness (%) relative to drying time (s). Figure 37 In the diagram, the drying time corresponds to the horizontal axis of the upper and lower graphs. The control unit 80 can also adjust the amount of cosmetic applied so that it is applied only when the dryness does not exceed a preset threshold. Figure 37 In the example shown, while the dryness level does not exceed 60% (a threshold), the control unit 80 causes the ingredient generation unit 40 to apply, for example, 4 mg of cosmetic. In other words, when the dryness level exceeds 60% (a threshold), the control unit 80 causes the ingredient generation unit 40 to stop applying the cosmetic. That is, the control unit 80 can also cause the cosmetic to be applied only when the hair is relatively moist.
[0212] Figure 38This is a time-series graph illustrating an example of the relationship between the amount of two cosmetics, A and B, applied and the degree of hair dryness. The top graph shows the amount (mg) of cosmetic A applied relative to drying time (s). The middle graph shows the amount (mg) of cosmetic B applied relative to drying time (s). Cosmetics A and B are different ingredients. Cosmetics A is an agent intended to penetrate the hair. Cosmetics B is a coating agent. The bottom graph shows the degree of dryness (%) relative to drying time (s). Figure 38 In the diagram, the drying time corresponds to the horizontal axis of the upper, middle, and lower graphs. The control unit 80 applies, for example, only 4 mg of cosmetic A to the ingredient generating unit 40 only when the dryness does not exceed a preset threshold, i.e., during the period when the hair is relatively moist. On the other hand, the control unit 80 applies, for example, only 4 mg of cosmetic B to the ingredient generating unit 40 only when the dryness exceeds a preset threshold, i.e., during the period when the hair is relatively dry. In other words, the control unit 80 can specifically apply cosmetic A, which is intended to penetrate the hair, during the period when the hair is moist, and specifically apply cosmetic B, which is intended to be a coating agent, during the period when the hair is dry.
[0213] Figure 39 This is a time-series graph illustrating an example of the relationship between airflow and hair dryness. The graph above shows the airflow (m³) relative to drying time (s). 3 / s). The graph below shows the degree of dryness relative to drying time (s). Figure 39 In the diagram, the drying time corresponds to the horizontal axis in the upper and lower figures. The control unit 80 can also adjust the airflow according to the degree of dryness of the hair. Specifically, as the hair gradually dries, the control unit 80 gradually reduces the airflow, while simultaneously increasing the temperature. As the hair gradually dries, the glass transition point rises. Therefore, by reducing the airflow as the hair dries, the curls in the hair can be straightened.
[0214] Next, the relationship between drying time and the degree of dryness of each part of the hair is explained.
[0215] Figure 40A and Figure 40B This is a graph illustrating the relationship between drying time and the degree of dryness of each part of the hair H. Figure 40A It is shown below Figure 40B The diagram shows a summary of the parts of hair H. Here, the four parts—the root surface, the inner side of the root, the hair tip surface, and the inner side of the hair tip—are used as comparison objects. Figure 40B A graph showing the degree of dryness (%) of each part of hair H relative to drying time (s) is presented. It can be seen that hair H dries more and more easily in the order of root surface, inside root, hair tip surface, and inside hair tip.
[0216] Next, the effects of hair dryer 1 will be explained.
[0217] The hair dryer 1, a hair care device according to this embodiment, includes: a heat application unit 30 that applies heat to the user's hair; a component generation unit 40 that generates components that act on the hair; and a measurement unit 50 that measures the hair. The hair dryer 1 also includes a control unit 80 that controls the operation of the heat application unit 30 and the component generation unit 40 based on hair measurement values obtained from the measurement unit 50. The control unit 80 includes a hair characteristic recognition unit 81, a table generation unit 82, and a dosage calculation unit 83. The hair characteristic recognition unit 81 classifies the user's hair characteristics based on the hair measurement values. The table generation unit 82 sets the component amount of the component generated by the component generation unit 40 for the hair characteristics classified by the hair characteristic recognition unit 81. The dosage calculation unit 83 adjusts the component amount for each user based on the overall hair characteristics classified by the hair characteristic recognition unit 81 and the component amount set by the table generation unit 82. Alternatively, the quantity calculation unit 83 calculates the component quantity provided by the component generation unit 40 or the heat quantity provided by the heat application unit 30 for each part of the hair based on the hair characteristics of each part of the hair classified by the hair characteristic recognition unit 81 and the component quantity set by the table generation unit 82.
[0218] In this embodiment, when applying heat or ingredients to a user's hair, the control unit 80 refers to the user's hair characteristics. Furthermore, the control unit 80 controls the heat application unit 30 or the ingredient generation unit 40 in a manner that reflects the user's hair characteristics, either by the user or by the location of the user's hair. Specifically, firstly, for each user on a whole-hair basis, a suitable amount of ingredient is preset according to the user's hair characteristics, and the ingredient generation unit 40 can apply ingredients to the hair at the preset optimal amount. Secondly, for each part of a user's hair, the hair can be applied with an optimal amount of ingredient or heat, further adjusted for each part, based on the amount of ingredient or heat set in the ingredient generation unit 82. In other words, the control unit 80 can perform highly precise control that is optimal for the user using the hair dryer 1.
[0219] Thus, according to this embodiment, a hair care device can be provided that easily achieves the hair effect desired by the user.
[0220] Additionally, in the hair dryer 1, hair characteristics can also be at least one of the user's hairstyle, hair length, hair amount, and hair texture related to hair thickness or shine.
[0221] According to this hair dryer 1, the hair characteristics that the control unit 80 can refer to can be varied in a large number of ways, and as a result, it is easier to obtain the hair effect that the user desires.
[0222] Additionally, the hair dryer 1 includes a display unit 73 that displays a segmented image obtained by dividing the hair into at least two parts in the front-back direction, left-right direction, or up-down direction. Alternatively, the control unit 80 may change the component quantity to the amount desired by the user based on the segmented portion selected by the user in the segmented image displayed on the display unit 73.
[0223] According to this hair dryer 1, the component amount set by the control unit 80 can be changed to the component amount preferred by the user using a split screen, thus making it easier to obtain the hair effect desired by the user.
[0224] Furthermore, in the hair dryer 1, the control unit 80 includes a wetting calculation unit 86, which calculates wetting information related to hair wetting based on hair measurement values. Alternatively, if the wetting calculation unit 86 determines that the user has not shampooed or that the hair is not wet, the hair characteristic recognition unit 81 performs hair characteristic classification. On the other hand, if the wetting calculation unit 86 determines that the hair is wet, the table generation unit 82 sets the component amount based on the hair characteristics classified by the hair characteristic recognition unit 81 up to the last time.
[0225] According to this hair dryer 1, the control unit 80 can obtain the user's hair characteristics based on the hair measurement value when the hair is in its normal state, and thus can set a better amount of ingredients to be applied.
[0226] Additionally, in the hair dryer 1, the control unit 80 includes a drying estimation calculation unit 87, which estimates the dryness of the hair based on hair measurement values. Alternatively, the quantity calculation unit 83 may also adjust the component quantity based on the dryness estimated by the drying estimation calculation unit 87.
[0227] According to this hair dryer 1, the control unit 80 adjusts the amount of ingredients while referring to the dryness of the hair during the drying operation, so as to impart an ingredient with an adjusted amount of ingredients to the hair.
[0228] Additionally, in the hair dryer 1, the measuring unit 50 has a wetting detection sensor 60a that sets at least the absorption wavelength of water to the hair measurement value. The wetting calculation unit 86 calculates the absorbance based on the hair measurement value detected by the wetting detection sensor 60a. Alternatively, the dryness estimation calculation unit 87 estimates the dryness based on the change in absorbance calculated by the wetting calculation unit 86.
[0229] Based on such a hair dryer 1, the control unit 80 can estimate the degree of dryness through a simpler structure or simpler control.
[0230] Additionally, in the hair dryer 1, the measuring unit 50 has an illumination unit 72 that illuminates light of at least the absorption wavelength of water. The wetting detection sensor 60a is a photodiode. Alternatively, the dryness estimation calculation unit 87 may estimate the degree of dryness by equalizing the degree of reflection of light from the illumination unit 72 based on the curvature of the user's head.
[0231] According to this hair dryer 1, the dryness can be estimated based on the shape of the user's head, thus making it easier to achieve the desired hair effect.
[0232] Furthermore, in the hair dryer 1, when the drying estimation calculation unit 87 determines that the dryness is at the atmospheric level, the control unit 80 performs at least one of the following actions. That is, the control unit 80 may perform at least one of the following actions: prevent the heat transfer unit 30 from transferring heat; stop the component generation unit 40 from transferring components; and even if the component generation unit 40 transfers components, it will not count the transfer time.
[0233] According to such a hair dryer 1, it is possible to minimize useless movements that are ineffective on the user's hair in the heat application section 30 or the component generation section 40.
[0234] Furthermore, in the hair dryer 1, when the dryness estimation calculation unit 87 determines that the dryness level is at the user's skin level, the control unit 80 performs at least one of the following actions: that is, the control unit 80 may perform at least one of the following actions: not applying heat to the heat application unit 30; and applying ingredients to the ingredient generation unit 40 to the skin with ingredients effective for the user.
[0235] This type of hair dryer 1 can especially increase the effectiveness of action on the user's skin.
[0236] Furthermore, the hair dryer 1 includes a transmit / receive unit 74 for transmitting and receiving data with the terminal communication unit 103 of the mobile terminal device 100, which is an external communication device. Here, it is assumed that the terminal display unit 101 of the mobile terminal device 100 displays at least a segmented image obtained by dividing the hair into at least two parts in the front-back, left-right, or up-down directions. In this case, the transmit / receive unit 74 may receive information from the terminal communication unit 103 related to the segmented portion selected by the user in the segmented image on the terminal display unit 101. Alternatively, the control unit 80 may change the component quantity to the amount desired by the user based on the information related to the segmented portion received by the transmit / receive unit 74 from the terminal communication unit 103.
[0237] According to this hair dryer 1, the user can adjust the settings of the hair dryer 1 from the mobile terminal device 100, thus improving the user's convenience.
[0238] (Second Implementation)
[0239] The hair dryer 1 described in the first embodiment uses a wetting detection sensor 60a (photodiode) as an example of the wetting detection unit 60. In contrast, the hair dryer 1 described in the second embodiment uses either of the two types of imaging units shown below as an example of the wetting detection unit 60 instead of the wetting detection sensor 60a.
[0240] Figure 41 This is a schematic perspective view showing the structure of a first example of a hair dryer 1, which is a hair care device according to the second embodiment. The hair dryer 1 according to the first example of this embodiment includes a camera unit 60b provided in place of the wetness detection sensor 60a in the first embodiment, and an illumination unit 72 provided in a manner that surrounds a portion of the nozzle 10b. Furthermore, in the hair dryer 1 here, the structure other than the camera unit 60b and the illumination unit 72 is the same as the structure in the first embodiment (except for the control unit 80 and the structure related to the control of the signal processing unit 90, etc.), so they are marked with the same reference numerals, and detailed descriptions are omitted.
[0241] Figure 42 This is a schematic perspective view showing the structure of a second example of a hair dryer 1, which is a hair care device according to the second embodiment. The hair dryer 1 according to this second embodiment includes a transmit / receive unit 74, which transmits and receives data with a mobile terminal device 100 (terminal communication unit 103), which is an external communication device. Here, the hair dryer 1 utilizes the terminal camera unit 102 of the mobile terminal device 100 as the camera unit of the wetness detection unit 60. Alternatively, the hair dryer 1 according to this second embodiment may also include a temperature sensor 60c (infrared sensor) instead of the wetness detection sensor 60a in the first embodiment. In this case, the illumination unit 72 is not required. Furthermore, when the temperature sensor 60c is used as the wetness detection unit 60, if... Figure 28 and Figure 29 As explained, the drying estimation calculation unit 87 can estimate the degree of dryness based on the temperature change of the hair relative to the drying time. Furthermore, in the hair dryer 1 described above, the structure of the first embodiment (except for the control unit 80 and the control-related structures such as the signal processing unit 90) is the same, so it is marked with the same reference numerals, and detailed descriptions are omitted.
[0242] First, when the imaging unit 60b or the terminal imaging unit 102 is used as the wetting detection unit 60, such as using Figure 28 and Figure 29As already explained, the dryness estimation calculation unit 87 can estimate the degree of dryness through machine learning based on hair images. In this case, the term "hair measurement value" used in the description of the hair dryer 1 according to the first embodiment can be replaced with "hair image" in this embodiment. Hereinafter, the machine learning will be explained in more detail using Figures 43 to 45.
[0243] In this embodiment, the drying estimation calculation unit 87 estimates the degree of dryness based on the drying time by machine learning based on teacher data of two-dimensional images (hair images) captured by the photography unit 60b and the like at the drying time.
[0244] Figure 43A and Figure 43B This is a schematic diagram showing an example of a two-dimensional image acquired according to the drying time when the wetting detection unit 60 is a photographic unit 60b. Figure 43A This is a schematic diagram illustrating the acquisition of two-dimensional images according to drying time. Figure 43B This is a schematic diagram illustrating the changes in a two-dimensional image as hair H gradually dries. (As shown...) Figure 43A and Figure 43B As shown, during the drying process, while the user changes the position of the hair dryer 1 to the positions shown by the first hair dryer 1a and the second hair dryer 1b, the imaging unit 60b acquires two-dimensional images according to the drying time. The acquired two-dimensional images are accumulated in the storage unit 75.
[0245] Figures 44A to 44C It is a diagram illustrating the process up to the point where the results of estimating the overall dryness of the hair based on the two-dimensional image are displayed. Figure 44A This is a graph showing the change in dryness (%) relative to the accumulated drying time. The dryness at the time the two-dimensional image was acquired can be used to obtain... Figure 44A The relationship shown is as described. Furthermore, as... Figure 44B As shown, it is possible to refer to all the acquired two-dimensional images and, based on Figure 44A The overall average approximate curve is used to estimate the dryness at a certain drying time. Figure 44C This is a schematic diagram showing an example of the overall dryness level displayed on the terminal display unit 101 of the mobile terminal device 100. Users can use this display to identify the dryness level of their hair at the current time.
[0246] Figures 45A to 45C This is a diagram illustrating the process up to the point where the results of the estimated average dryness of the head and hair ends based on the two-dimensional image are displayed. Figure 45A and Figure 44A Similarly, a graph showing the change in dryness (%) relative to the accumulated drying time is presented. In this case, as... Figure 45BAs shown, the acquired two-dimensional images can be classified by location, such as more moist areas X and more dry areas Y. Furthermore, it can be based on... Figure 45A The dryness of each part at a certain drying time is estimated by using approximate curves of the head average and hair tip average. Figure 45C This is a schematic diagram showing an example of displaying the dryness of each part of the hair on the terminal display unit 101 of the mobile terminal device 100. Users can identify the dryness of each part of the hair at the current point in time through this display.
[0247] As described above, in the hair dryer 1 according to the second embodiment, for example, the measuring unit 50 has a photographic unit 60b that sets a two-dimensional image as a hair image. The drying estimation calculation unit 87 can also estimate the degree of dryness according to the drying time by machine learning based on teacher data of two-dimensional images obtained by the photographic unit 60b taking pictures according to the drying time. Alternatively, in the hair dryer 1 according to the second embodiment, the drying estimation calculation unit 87 may estimate the degree of dryness for each part of the hair.
[0248] The hair dryer 1 according to this second embodiment has the same effect as the hair dryer 1 according to the first embodiment.
[0249] (Third Implementation)
[0250] The wetting detection unit 60 can also be a moisture sensor that directly measures the moisture content of hair by contacting the user's hair.
[0251] Figure 46 This is a schematic cross-sectional view showing the structure of a hair dryer 1 according to the third embodiment of the hair care device. The hair dryer 1 according to this embodiment does not include the wetness detection sensor 60a and the illumination unit 72 included in the hair dryer 1 of the first embodiment. On the other hand, the hair dryer 1 according to this embodiment includes a brush unit 22 mounted at the nozzle 10b and a moisture sensor 60d provided on the brush unit 22. Here, the other structures of the hair dryer 1 are the same as those in the first embodiment (except for the control unit 80 and the structures related to control such as the signal processing unit 90), therefore, they are marked with the same reference numerals, and detailed descriptions are omitted.
[0252] In this case, the hair measurement value is the moisture content of the hair. The moisture sensor 60d can measure the moisture content of the hair while the user is drying it by contacting the brush part 22 with the hair. Furthermore, the drying estimation calculation unit 87 can estimate the degree of dryness based on the acquired moisture content.

[0255] Figure 47 This is a schematic perspective view showing the structure of a hair curler 200, which is a hair care device according to the fourth embodiment. The hair curler 200 includes a first main body 201 and a second main body 202 that clamp the user's hair in an opposing manner. A heating plate 203 is provided on the opposing surface of at least one of the first main body 201 and the second main body 202 to serve as a heat-applying part that replaces the heat-applying part 30 in the hair dryer 1. In this case, the part expressed as "drying" in the description of the hair dryer 1 according to the first embodiment can be replaced with "styling (or forming a hairstyle)" in this embodiment.
[0256] For example, the first main body 201 may internally include a component generation unit 40 and a control unit 80, as described in the above embodiments. In the first main body 201, a component spray outlet 210f corresponding to the component spray outlet 10f in the hair dryer 1 may also be located near the heating plate 203. Furthermore, the first main body 201 may also include an input section 271 corresponding to the input section 71 in the hair dryer 1. In this case, the input section 271 consists of three input buttons: a hair texture input section 271a, a hair length input section 271b, and a hair volume input section 271c.
[0257] On the other hand, for example, the second main body 202 may also include a moisture detection sensor 260a corresponding to the moisture detection sensor 60a in the hair dryer 1 and an illumination unit 272 corresponding to the illumination unit 72 in the hair dryer 1. The moisture detection sensor 260a and the illumination unit 272 may also be respectively provided near the position facing the heating plate 203.

The hairbrush 300 has a main body 301 with one of its front ends designated as a brush head 301a. The brush head 301a has a comb portion 322 and a spray outlet 310b corresponding to the spray outlet 10b in the hair dryer 1.
[0262] For example, the main body 301 may internally include a heat application section 30, a component generation section 40, and a control section 80, as described in the above embodiments. In the brush head 301a, a component spray outlet 310f corresponding to the component spray outlet 10f in the hair dryer 1 may be located near the spray outlet 310b. Similarly, in the brush head 301a, a moisture detection sensor 360a corresponding to the moisture detection sensor 60a in the hair dryer 1 and an illumination section 372 corresponding to the illumination section 72 in the hair dryer 1 may be located near the spray outlet 310b. Furthermore, the main body 301 may also include an input section 371 corresponding to the input section 71 in the hair dryer 1 and a power switch 376 corresponding to the power switch 76 in the hair dryer 1. In this case, the input section 371 consists of three input buttons: a hair texture input section 371a, a hair length input section 371b, and a hair volume input section 371c.
[0263] This hairbrush 300 achieves the same effect as the hair dryer 1 exemplified above.

First, the hair care system 110 includes the hair care device and mobile terminal device 100 according to the various embodiments described above. Figure 49 In the example, the hair dryer 1 according to the first embodiment is used as a hair care device. Additionally, in... Figure 49 In the illustration, two mobile terminal devices 100 are shown as an input device and an output device, but this is a simplified representation of the input / output path of information; these mobile terminal devices 100 are the same device. That is, the hair care system 110 includes a hair dryer 1 and a mobile terminal device 100 as the hair care device described in the various embodiments above. The hair dryer 1 has a transmit / receive unit 74, and the mobile terminal device 10 has a terminal communication unit 103 that transmits and receives data with the transmit / receive unit 74.
[0267] Additionally, a server 120 for managing various information exists outside the hair care system 110. The hair care system 110 can exchange information with the server 120 via a web application 121. Furthermore, the server 120 can also exchange information with, for example, a data analysis application 122 maintained by a data management professional.
[0268] First, the control unit 80 within the hair dryer 1 can send user U's hair information and drying operation information to the mobile terminal device 100. The mobile terminal device 100 sends the hair information received from the hair dryer 1 to the server 120 via the web application 121. The server 120 manages this information. The information managed by the server 120 is analyzed by the data analysis application 122. The web application 121 obtains the analysis results from the server 120 and sends them to the mobile terminal device 100 as user analysis information and device control information. The user analysis information is displayed on the terminal display unit 101 of the mobile terminal device 100, and the device control information is sent to the hair dryer 1. On the other hand, the user can send personal information, questionnaires, and other user information from the mobile terminal device 100 to the web application 121. In addition, the user can obtain and view hair diagnosis information from the web application 121 via the mobile terminal device 100.
[0269] According to this hair care system 110, information such as the optimal amount of ingredients for the user obtained by the hair dryer 1 can be analyzed and fed back to the user, thus further improving the user's convenience.
