[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of the components are also the same. Therefore, detailed description thereof will not be repeated.

[0010] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail. (Overall structure of the hair dryer) Fig. 1 is a perspective view showing the external configuration of a hair dryer 10 according to this embodiment. For convenience in describing the shapes and positional relationships of the components of the hair dryer 10, the hair dryer 10 will be defined by three coordinate axes, namely, the X (X1-X2) direction (left-right direction), the Y (Y1-Y2) direction (up-down direction), and the Z (Z1-Z2) direction (front-back direction), as shown in Fig. 1 etc.

[0011] Fig. 2 shows the appearance of the hair dryer 10 shown in Fig. 1 as seen from the side (X2 side). Fig. 3 shows a cross section of the hair dryer 10 shown in Fig. 1 as seen from the side (X2 side).

[0012] As shown in FIG. 1, the hair dryer 10 is mainly composed of a main body 11 and a grip 20. The main body 11 has an air outlet 12 formed on the front side (Z1 side) of the front part 11a for blowing out air, and an air inlet 23 formed on the rear side (Z2 side) for drawing in air. The main body 11 also has an internal air blowing mechanism (air blower 150 (FIG. 3), etc.) and an air outlet path (air blowing path). As a result, the main body 11 blows out the air drawn in through the air inlet 23 from the air outlet 12 (specifically, the first air outlet 12a and the second air outlet 12b). In addition to blowing hot and cold air, the hair dryer 10 may also generate charged particles (ions) and blow them onto the head.

[0013] 3, blower 150 has at least centrifugal fan 151, motor 153, and motor fixing part 152. By driving motor 153 to rotate centrifugal fan 151, air is drawn in through intake port 23 of main body 11, heated or cooled inside, and blown out from outlet 12.

[0014] The air outlet 12 is composed of two air outlets, a first air outlet 12a and a second air outlet 12b, which are formed at the left and right (X1-X2) ends of the front surface 11a. That is, the first air outlet 12a and the second air outlet 12b are formed on the left and right (X1-X2) outer edge sides of the front surface 11a of the main body 11.

[0015] The first air outlet 12a is formed in the vertical direction (Y direction) along the left end (X1 side) of the front portion 11a when viewed from the front, and the second air outlet 12b is formed in the vertical direction (Y direction) along the right end (X2 side) of the front portion 11a when viewed from the front.

[0016] The first air outlet 12a and the second air outlet 12b have openings that are elongated (vertically long) in the vertical direction (Y direction). More specifically, the first air outlet 12a and the second air outlet 12b are formed in an arc shape along part of the outer periphery of the substantially circular front portion 11a. Because the openings of the first air outlet 12a and the second air outlet 12b have such shapes, when drying hair using the hair dryer 10, the longitudinal direction of each opening can be aligned with the direction in which the hair grows at the treatment area. The front surface 11a is provided with a display unit 30 and an illuminating unit 50 (first illuminating unit 50a, second illuminating unit 50b) formed inside the first air outlet 12a and the second air outlet 12b. Details of the display unit 30, the first illuminating unit 50a, and the second illuminating unit 50b will be described later.

[0017] The grip part 20 is located below the main body 11. The grip part 20 is a part that a user holds when using the hair dryer 10. As shown in FIG. 2, when the hair dryer 10 is viewed from the side (for example, the X2 side), the grip part 20 extends downward (to the Y2 side) from approximately the center of the main body 11 in the front-to-rear direction (Z direction).

[0018] The Z1 side of the grip part 20 constitutes the front part 20a. The front part 20a of the grip part 20 is provided with an operation part 40. When using the hair dryer 10, the user operates the operation part 40 (specifically, the power switch 42) to start or stop the operation of the hair dryer 10. In addition, by operating the operation part 40 (specifically, the operation button 41), the type of air (hot air / cold air) and the air volume blown out from the air outlet 12 can be adjusted. In addition, by operating the operation part 40 (specifically, the operation button 41), the operation mode of the hair dryer 10 can be switched.

[0019] A power cord 22 is attached to the lower part of the grip part 20. In another embodiment of the present invention, the hair dryer 10 may be a cordless type. In this case, for example, a primary or secondary battery is provided inside the main body 11 or the grip part 20.

[0020] (About the external shape of the hair dryer) Next, the external shape of the hair dryer 10 will be described.

[0021] As shown in Fig. 2, the hair dryer 10 has a substantially T-shape in side view. Also, as shown in Fig. 1, the front side (Z1 side) of the hair dryer 10 is composed of a substantially circular front portion 11a, a substantially rectangular front portion 20a that is narrower than the front portion 11a, and an inclined surface 20b whose width gradually narrows from the front portion 11a toward the front portion 20a.

[0022] The display unit 30, the first irradiation unit 50a, the second irradiation unit 50b, and the operation unit 40 are all arranged on the front side (Z1 side) of the hair dryer 10. In addition, at least one of the multiple operation buttons 41 that make up the operation unit 40 is arranged on the inclined surface 20b.

[0023] As shown in FIG. 1, the substantially circular front portion 11a has a left end portion 13a located on the leftmost side when viewed from the Z1 side, a right end portion 13b located on the rightmost side, an upper end portion 14a located on the uppermost side, and a lower end portion 14b located on the lowermost side.

[0024] As shown in FIG. 1 and other figures, the front surface 11a has a curved, concave shape. Furthermore, in the front surface 11a having this curved, concave shape, the ends in the left-right direction (X direction) (i.e., the left end 13a and the right end 13b) are located closer to the front (Z1 side) than the ends in the up-down direction (Y direction) (i.e., the upper end 14a and the lower end 14b) in a side view and a top view (or a bottom view). That is, the ends in the up-down direction (Y direction) of the main body 11 are recessed further upstream (Z2 side) in the airflow than the ends in the left-right direction (X direction) of the main body 11. Furthermore, in the front surface 11a having a concave shape, the lower end 14b is recessed further upstream (Z2 side) in the airflow than the upper end 14a in a bottom view.

[0025] The display unit 30 is disposed near the center of the front surface 11a, which is recessed from the left-right (X-direction) ends 13a and 13b where the first air outlet 12a and the second air outlet 12b are provided. The display unit 30 is also disposed on the lower end 14b side of the front surface 11a, which does not protrude forward (toward the Z1 side) from the upper end 14a.

[0026] As a result, for example, as shown in FIG. 1, when a user looks at the front portion 11a of the hair dryer 10 from the diagonal front side, the contents of the display unit 30 can be confirmed. If the front portion 11a has a flat shape, it may be difficult to confirm the information on the display unit 30 located between the first air outlet 12a and the second air outlet 12b due to the influence of light reflection, etc. In contrast, in this embodiment, the display unit 30 is provided in a recessed portion of the front portion 11a, which has a curved concave shape, thereby reducing the influence of light reflection and making it easier to confirm the display unit 30. Furthermore, this configuration makes it possible to confirm the display unit 30 from a wider range of directions (for example, from a steeply inclined oblique direction).

[0027] (About the front structure of the hair dryer) Next, the configuration of the front portion of the hair dryer 10 will be described with reference to Figure 4. The front portion of the hair dryer 10 is mainly composed of a front portion 11a of the main body 11, a front portion 20a of the grip portion 20, and an inclined surface 20b.

[0028] A first air outlet 12a is provided on the left side of the front surface 11a as viewed from the Z1 side, along the outer periphery of the front surface 11a. A second air outlet 12b is provided on the right side of the front surface 11a as viewed from the Z1 side, along the outer periphery of the front surface 11a. The first air outlet 12a extends vertically around the left end 13a. The second air outlet 2b extends vertically around the right end 13b.

[0029] The front surface 11a has a concave shape between the first air outlet 12a and the second air outlet 12b. That is, the center of the front surface 11a (where the distance sensor 60 is formed) is recessed furthest to the rear (upstream in the airflow direction). In this embodiment, the center has a substantially flat shape.

[0030] A first irradiation unit 50a is provided between the first air outlet 12a and the central portion, and a second irradiation unit 50b is provided between the second air outlet 12b and the central portion. That is, the first irradiation unit 50a and the second irradiation unit 50b are formed inside the positions where the first air outlet 12a and the second air outlet 12b are formed on the front surface 11a of the main body 11, respectively. Furthermore, on the front surface 11a of the main body 11, a display unit 30 for displaying the operating state of the hair dryer 10 is provided inside the first irradiating unit 50a and the second irradiating unit 50b. Below the center of the front surface 11a and on the outer periphery of the center, there are operation mode display sections 31 (31a to 31f) that display the operation mode, which constitute part of the display section 30, and above the center there is a temperature display section 32. In this way, the display section 30 is disposed in a recessed position upstream in the air blowing direction from the air outlet 12, which is located at the downstream end of the air blowing path. In other words, the display section 30 is disposed in a recessed position in the front surface 11a. Furthermore, a distance sensor 60 is formed in the center of the front part 11a. This distance sensor 60 measures the distance from the hair dryer 10 to the user (head) of the hair dryer 10. The measured value by the distance sensor 60 is used to control various operations of the hair dryer 10.

[0031] An operation unit 40 is provided on the inclined surface 20b located below the front surface 11a and on the front surface 20a of the grip portion 20. The operation unit 40 has a plurality of operation buttons 41 and a power switch .

[0032] (About the display) Next, we will explain the specific configuration of the display unit 30. The display unit 30 is arranged on the downstream end side of the airflow outlet path (i.e., the front surface 11a). The display unit 30 is made up of an operation mode display unit 31 and a temperature display unit 32.

[0033] The operation mode display unit 31 is a display unit for displaying various operation modes of the hair dryer 10, such as normal mode, quick dry mode, styling mode, hair care mode (ion blow mode), etc. In this embodiment, the operation mode display unit 31 is composed of six LED lamps 31a to 31f.

[0034] 4, the plurality of LED lamps 31a, 31b, 31c, 31d, 31e, and 31f that make up the operation mode display unit 31 are arranged in a vertical line (Y direction) below the front part 11a. When a user of the hair dryer 10 operates the operation button 41 of the operation unit 40, the operation mode of the hair dryer 10 is switched. Then, among the plurality of LED lamps 31a, 31b, 31c, 31d, 31e, and 31f, an LED lamp that corresponds to the selected current operation mode is turned on.

[0035] In one example, when the operation mode of the hair dryer 10 is the normal mode, only the top LED lamp 31a is lit. When the operation mode of the hair dryer 10 is the quick dry mode, only the second LED lamp 31b from the top is lit. When the operation mode of the hair dryer 10 is the styling mode, only the third LED lamp 31c from the top is lit. When the operation mode of the hair dryer 10 is the hair care mode, only the bottom LED lamp 31d is lit. When the operation mode of the hair dryer 10 is the scalp care mode (1), only the LED lamp 31e is lit. When the operation mode of the hair dryer 10 is the scalp care mode (2), only the LED lamp 31f is lit. The multiple LED lamps 31a, 31b, 31c, 31d, 31e, and 31f that make up the operation mode display unit 31 are arranged vertically in approximately the center of the front part 11a in the left-right direction (X direction) between the first air outlet 12a and the second air outlet 12b. The LED lamps 31a, 31b, 31c, 31d, 31e, and 31f are also arranged on an extension of a center line that passes through approximately the center of the front part 20a. This makes it easier for the user to check which of the multiple LED lamps 31a, 31b, 31c, 31d, 31e, and 31f is lit. Therefore, the user can easily check the current operation mode while using the hair dryer 10.

[0036] The temperature display unit 32 indicates the temperature of the air blown out from the air outlet 12, such as hot air / cold air. The temperature display unit 32 indicates the temperature of the air, for example, by color. Specifically, when hot air is blown out, the temperature display unit 32 turns red, and when cold air is blown out, the temperature display unit 32 turns blue.

[0037] In this case, the temperature display unit 32 is composed of a red LED lamp, a blue LED lamp, etc. When hot air is blown out from the air outlet 12, the red LED lamp lights up and emits a color. When cold air is blown out from the air outlet 12, the blue LED lamp lights up and emits a color. This allows the user to easily distinguish whether the air being blown out is hot air or cold air.

[0038] (Irradiation unit) As shown in Fig. 4, the first irradiation unit 50a and the second irradiation unit 50b each include two red LEDs 51a (red light irradiation units) that irradiate red light and two blue LEDs 51b (blue light irradiation units) that irradiate blue light. In the first irradiation unit 50a and the second irradiation unit 50b, the red LEDs 51a and the blue LEDs 51b are arranged around the display unit 30. In this embodiment, as shown in Fig. 4, the red LEDs 51a and the blue LEDs 51b are arranged to sandwich the display unit 30 from the left and right (X1-X2) directions, but the present invention is not limited to this. The red LEDs 51a and blue LEDs 51b of the first irradiation unit 50a are arranged along the first air outlet 12a. Here, from the Y1 side to the Y2 side, the red LEDs 51a, blue LEDs 51b, blue LEDs 51b, and red LEDs 51a are arranged in a line at approximately equal intervals. That is, the two blue LEDs 51b are arranged adjacent to each other, and the two red LEDs 51a are arranged with two adjacent blue LEDs 51b interposed between them. Note that the red LEDs 51a and blue LEDs 51b may be arranged such that the centers of the LEDs are positioned on a straight line, or may be arranged such that the centers of the LEDs are positioned on an arc-shaped virtual line that follows the arc-shaped first air outlet 12a.

[0039] Similarly, the red LEDs 51a and blue LEDs 51b of the second irradiation unit 50b are arranged along the second air outlet 12b. Here, for example, the red LEDs 51a, blue LEDs 51b, blue LEDs 51b, and red LEDs 51a are arranged at approximately equal intervals from the Y1 side to the Y2 side. That is, the two blue LEDs 51b are arranged adjacent to each other, and the two red LEDs 51a are arranged with two adjacent blue LEDs 51b interposed between them. Note that the red LEDs 51a and blue LEDs 51b may be arranged such that the centers of the LEDs are positioned on a straight line, or may be arranged such that the centers of the LEDs are positioned on an arc-shaped virtual line along the arc-shaped second air outlet 12b. The first and second irradiation units 50a and 50b are configured to irradiate LED light in the same direction as the airflow blowing out from the first and second air outlets 12a and 12b. This allows the LED light irradiated from the first and second irradiation units 50a and 50b to be irradiated onto the scalp together with the airflow blown out from the first and second air outlets 12a and 12b, as shown in FIG.

[0040] Here, the red LED light emitted from the red LED 51a is light in the wavelength range of 618 nm to 635 nm, and the blue LED light emitted from the blue LED 51b is light in the wavelength range of 405 nm to 415 nm. Irradiating the scalp with either type of LED light is expected to improve the scalp environment.

[0041] 5, the LED light emitted from the first irradiation unit 50a and the second irradiation unit 50b is irradiated onto the scalp together with the air blown out from the first air outlet 12a and the second air outlet 12b, thereby achieving the effect of improving the scalp environment while drying or styling the hair on the scalp.

[0042] Moreover, the hair dryer 10 having the above-described configuration has the first irradiation unit 50a and the second irradiation unit 50b provided on the front surface 11a inside the first air outlet 12a and the second air outlet 12b, respectively, which has the advantage of not increasing the overall dimensions compared to when the irradiation units are provided outside the main body 11.

[0043] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0044] The hair dryer according to this embodiment has almost the same configuration as the hair dryer 10 according to the first embodiment, but differs in that the optical axes of the red LED 51a and the blue LED 51b of the first irradiation unit 50a and the second irradiation unit 50b are tilted.

[0045] As shown in Figure 6, the optical axes of the red LED 51a and blue LED 51b included in the hair dryer 10A according to this embodiment are adjusted so that red light and blue light can be effectively irradiated onto the scalp. For example, by adjusting the inclination of the optical axes of the red LED 51a and blue LED 51b, it is possible to irradiate light of each color within approximately the same range.

[0046] The inclination of the optical axis may be adjusted in advance, assuming a typical distance from the scalp to the hair dryer 10A when the hair dryer 10A is in use.

[0047] Alternatively, the red LED 51a and the blue LED 51b may be movably supported to adjust the tilt of the optical axis according to the distance from the scalp to the hair dryer 10A. Specifically, the output value of the distance sensor 60 provided in the hair dryer 10A is used to move the red LED 51a and the blue LED 51b, thereby adjusting the tilt of the optical axis of each of the red LED 51a and the blue LED 51b.

[0048] As described above, by tilting the optical axes of the red LED 51a and the blue LED 51b, it is possible to effectively irradiate the scalp with the LED light emitted from the first irradiating unit 50a and the second irradiating unit 50b.

[0049] In the above-described embodiments, the number of red LEDs 51a and the number of blue LEDs 51b included in the first irradiation unit 50a and the second irradiation unit 50b are two, respectively, but this is not limited to this. Furthermore, the arrangement of the red LEDs 51a and the blue LEDs 51b is not limited to the order of red LED 51a, blue LED 51b, blue LED 51b, red LED 51a.

[0050] For example, the first irradiation unit 50a may include one red LED 51a and one blue LED 51b, and the second irradiation unit 50b may also include one red LED 51a and one blue LED 51b. Alternatively, the first irradiation unit 50a and the second irradiation unit 50b may only include LEDs of the same color. For example, the first irradiation unit 50a may include two or more red LEDs 51a (or blue LEDs 51b), and the second irradiation unit 50b may also include two or more red LEDs 51a (or blue LEDs 51b).

[0051] 〔summary〕 The hair dryer according to aspect 1 of the present invention includes a main body 11, an air blowing section (air blowing mechanism) provided within the main body 11, an air outlet 12 for blowing out air from the air blowing section (air blowing mechanism), and an irradiation section 50 for irradiating light, wherein the air outlet 12 (first air outlet 12a and second air outlet 12b) are formed on the left and right sides of the outer edge of the front surface (front surface 11a) of the main body 11, and the irradiation section 50 (first irradiation section 50a, second irradiation section 50b) are formed inside the formation position of the air outlet 12 (first air outlet 12a and second air outlet 12b) on the front surface of the main body 11.

[0052] According to the above configuration, since the irradiation unit is formed inside the position of the air outlet on the front of the main body, it is possible to efficiently blow the air blown out from the air outlet onto the area irradiated with light by the irradiation unit. As a result, if the irradiated area is the scalp, the air blown out from the air outlet can brush aside the hair covering the scalp, making it possible to efficiently irradiate the scalp with light. In other words, since the air outlets are separated into left and right when viewed from the front, the two air flows blown out from the hair dryer create a difference in air speed between the front position of each air outlet (high air speed area) and the intermediate position of each air outlet (low air speed area), and this difference can brush aside the hair in a three-dimensional manner, making it possible to efficiently irradiate the scalp with light.

[0053] The hair dryer according to aspect 2 of the present invention may be configured in the above-mentioned aspect 1 such that a display unit 30 is provided on the front (front unit 11a) of the main body unit 11, inside the irradiation unit 50 (first irradiation unit 50a, second irradiation unit 50b), for displaying the operating status of the hair dryer.

[0054] According to the above configuration, it is possible to grasp the operating state of the hair dryer simply by looking at the front of the hair dryer.

[0055] A hair dryer according to aspect 3 of the present invention may be such that, in aspect 2 above, the front surface (front surface 11a) of the main body 11 is recessed toward the center (central portion 15), and the display unit 30 is positioned in a recessed position on the front surface (front surface 11a).

[0056] According to the above configuration, the display unit 30 is provided in the recessed portion on the front surface having a curved concave shape, which reduces the influence of light reflection and makes it easier to check the display unit.

[0057] A hair dryer according to aspect 4 of the present invention is the same as that according to aspect 2 or 3 above, wherein the irradiation unit 50 (first irradiation unit 50a, second irradiation unit 50b) comprises a plurality of light sources (red LED 51a, blue LED 51b), and the plurality of light sources (red LED 51a, blue LED 51b) may be arranged to surround the display unit 30.

[0058] According to the above configuration, it becomes easy to distinguish between light emitted from the display unit and light emitted from the illumination unit.

[0059] A hair dryer according to aspect 5 of the present invention is such that, in aspect 4, the light source (red LED 51a, blue LED 51b) may be at least one of a red light irradiation unit (red LED 51a) that emits red light and a blue light irradiation unit (blue LED 51b) that emits blue light.

[0060] A hair dryer according to a sixth aspect of the present invention is configured such that, in the fifth aspect, the plurality of light sources (red LEDs 51a, blue LEDs 51b) include at least two red light irradiating units (red LEDs 51a) and at least two blue light irradiating units (blue LEDs 51b) arranged in a row along the formation position of the air outlet 12 (first air outlet 12a, second air outlet 12b), and the blue light irradiating units (blue LEDs 51b) are arranged adjacent to each other, and the red light irradiating unit (red LED 51a) may be arranged outside the adjacent blue light irradiating unit (blue LED 51b).

[0061] According to the above configuration, the scalp is irradiated with at least one of red light from the red LED and blue light from the blue LED, which is expected to improve the scalp environment.

[0062] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. Furthermore, new technical features can be formed by combining the technical means disclosed in each embodiment. [Explanation of symbols]
