[0008] Hereinafter, embodiments of the hair dryer involved in the present disclosure will be described with reference to the accompanying drawings. The present disclosure is not limited to the contents described in the following embodiments, and design changes can be appropriately made within the scope of the configuration of the present disclosure. In the drawings, the same or equivalent elements are marked with the same reference numerals, and repeated descriptions are omitted.

[0009] In the present disclosure, a "hair dryer" refers to any device that can dry a dry object such as human or animal hair (e.g., hair). The temperature of the air blown out by the hair dryer is not particularly limited. The hair dryer may be, for example, a device that blows out cold air or a device that blows out heated warm air. The hair dryer includes devices having a drying function and functions other than the drying function. For example, a hair dryer may have a function of imparting a beauty effect to the skin or scalp by blowing low-temperature air containing charged particles.

[0010] "Flow direction" and "flow path direction" refer to the flow direction of wind on an imaginary line formed by connecting the centers of the flow paths. The center of the flow path refers to the centroid of the internal shape in the cross section of the flow path. "Flow direction" and "flow path direction" may also be directions extending along a straight line, for example, in the case where there are bends or folds in the flow path, part or all of the direction may also be along the bend or folded imaginary line. In this case, the "flow direction" and "flow path direction" may be composed of different vectors at different locations in the direction of extension of an imaginary line connecting the centers of the flow paths (the imaginary line is also referred to as the "flow path center line").

[0011] When two lines or planes are "parallel", it means that the angle (absolute value) between them is within the range of 0°±3°. In addition, when two lines or planes are "perpendicular", it means that the angle (absolute value) between them is within the range of 90°±3°.

[0012] (Implementation Method 1) Figures 1 to 4 : is a schematic diagram roughly showing the appearance of the hair dryer 1 of this embodiment. Figure 1 is the main view, Figure 2 is the right view, Figure 3 is the rear view, Figure 4 It is a top view. Figure 5 It is a cross-sectional schematic diagram roughly showing the internal structure of the hair dryer 1 of this embodiment. Fig.13 1 is a block diagram showing the structure of the hair dryer 1 of this embodiment. Figures 1 to 3 and Figure 5 The up-and-down direction corresponds to the first direction.

[0013] The hair dryer 1 includes a plurality of blow-out parts 2, an actuator 6, and a control unit 7 as main components. The plurality of blow-out parts 2 include a first blow-out part 21 and a second blow-out part 22. The hair dryer 1 also includes a main body 3 to which the first blow-out part 21 and the second blow-out part 22 are mounted, for example, the main body 3 includes the actuator 6 and the control unit 7. Sometimes, the first blow-out part 21 and the second blow-out part 22 are collectively referred to as the blow-out part 2.

[0014] The first blow-out portion 21 includes a first blow-out port 21a formed elongated along the first direction. The second blow-out portion 22 includes a second blow-out port 22a formed elongated along the first direction. The first blow-out port 21a and the second blow-out port 22a are openings for blowing the air sucked from the main body 3 by the first blow-out portion 21 and the second blow-out portion 22 to the outside, respectively. The internal space of the first blow-out portion 21 becomes a flow path for the air sucked from the main body 3 to flow to the first blow-out port 21a, and the internal space of the second blow-out portion 22 becomes a flow path for the air sucked from the main body 3 to flow to the second blow-out port 22a. These flow paths are preferably parallel to each other and preferably have the same flow path area. In other words, the first blow-out portion 21 and the second blow-out portion 22 preferably have the same cross-sectional area at the same position in the flow direction of their internal spaces. The first blow-out port 21a and the second blow-out port 22a are sometimes also collectively referred to as blow-out port a.

[0015] The first outlet 21a and the second outlet 22a each have an elongated shape with the first direction as the long side direction. Figures 1 to 3 and Figure 5 The first direction is defined as the first direction (corresponding to the up and down direction in the figure). Air (also called wind) is blown out from the first outlet 21a in a second direction inclined relative to the first direction, and air is blown out from the second outlet 22a in a second direction inclined relative to the first direction. The second direction is typically a direction perpendicular to the first direction (e.g., Figure 2In addition, the first direction is preferably a direction along the extension direction of the hair. The details of the blow-out port a will be described later.

[0016] The first blowing part 21 and the second blowing part 22 are arranged to be spaced apart from each other. For example, the first blowing part 21 and the second blowing part 22 are preferably arranged to be spaced apart from each other along a second direction inclined relative to the first direction. The second direction is typically a direction perpendicular to the first direction (in Figures 1 to 3 and Figure 5 In addition, the first blowing part 21 and the second blowing part 22 are preferably arranged in parallel. Figure 1 As in the hair dryer 1 shown in the figure, the first blow-out part 21 and the second blow-out part 22 are preferably arranged in parallel along a first direction and spaced apart from each other along a direction perpendicular to the first direction.

[0017] At least one of the first blowing part 21 and the second blowing part 22 is rotatable. For example, at least one of the first blowing part 21 and the second blowing part 22 is preferably rotatably connected to the main body 3 around an axis extending in the first direction. In this case, at least one of the first blowing part 21 and the second blowing part 22 can be rotated in a direction perpendicular to the first direction (corresponding to Figure 4 At least one of the first blowing portion 21 and the second blowing portion 22 may also rotate in other directions (for example, the first direction which is the long side direction of the blowing outlet a).

[0018] The first blowing part 21 and the second blowing part 22 may both be rotatable, or only one of them may be rotatable. In addition, at least one of the first blowing part 21 and the second blowing part 22 may be formed of a flexible member.

[0019] The rotatable blower is preferably capable of being locked and rotated at any angle. For example, it is preferred that at least one blower can be locked at an angle at which the first blower 21a and the second blower 22a clamp the hair. The rotation angle is not particularly limited, but for example, the rotatable angle of one blower is 0 to 360 degrees.

[0020] When both the first blow-out part 21 and the second blow-out part 22 are rotatable, they can rotate in the same direction or in different directions. In addition, the rotational locking position can be, for example, a symmetrical position relative to a plane passing through the middle of the first blow-out part 21 and the second blow-out part 22 and extending along the first direction, or an asymmetrical position. In addition, for example, the rotation directions of the first blow-out part 21 and the second blow-out part 22 can be controlled to be the same rotation direction or to be controlled to be opposite rotation directions. In addition, for example, in addition, for example, it is also possible to control so that the rotation direction of the first blow-out part 21 and the rotation direction of the second blow-out part 22 alternately appear in the same direction and in the opposite direction as time passes. "Rotation direction" refers to the rotation direction when the blow-out part 2 is observed from the first direction. The rotation direction includes clockwise (right-hand rotation) and counterclockwise (left-hand rotation). The details of the blow-out part 2 will be described later.

[0021] The actuator 6 is a component that drives at least one of the first blowing section 21 and the second blowing section 22 so that the opening direction of the blowing outlet of the driven blowing section can be changed. As the actuator 6, an electric actuator is preferably used, but a hydraulic actuator or a pneumatic actuator can also be used. The electric actuator can be, for example, a piezoelectric actuator using a piezoelectric element, or a servo actuator using a servo motor. The actuator 6 includes, for example, a motor and a gear, and can have a plurality of motors.

[0022] The actuator 6 drives at least one of the first blowing part 21 and the second blowing part 22 based on the instruction from the control unit 7. The actuator 6 can, for example, rotate at least one of the first blowing part 21 and the second blowing part 22 in a direction perpendicular to the first direction with the axis extending along the first direction as the center. The actuator 6 can also rotate in a direction other than the above (for example, the first direction as the long side direction of the blowing outlet). When the blowing part rotates, the opening direction of the blowing outlet provided by the blowing part changes, so the wind direction of the wind blown out from the blowing outlet changes.

[0023] The opening direction of the outlet a refers to the direction in which the centroid of the outlet faces, which is substantially equivalent to the flow direction (wind direction) of the wind near the outlet a. The flow direction of the wind blown out from the first outlet 21a is also referred to as the wind direction d1, and the flow direction of the wind blown out from the first outlet 21a is also referred to as the wind direction d2. The opening direction a1 of the first outlet 21a is substantially equivalent to the wind direction d1, and the opening direction a1 of the second outlet 22a is substantially equivalent to the wind direction d2.

[0024] The control unit 7 appropriately controls each part based on the operation instruction of the hair dryer 1 from the user or the like. The operation instruction of the hair dryer 1 from the user or the like is, for example, an instruction to start operation (operation ON), stop operation (operation OFF), set or change the operation mode, air volume, air temperature, etc. The control unit 7 is composed of a CPU, etc., and executes a program stored in a storage device. The control unit 7 may also be a microcomputer having a CPU and a storage device, etc. In addition to controlling the actuator 6, the control unit 7 may also control the blow-out fins, electric blower, heater, air intake fins, etc. described later.

[0025] The control unit 7 drives the actuator 6 based on the presence or absence of hair between the first blow-out unit 21 and the second blow-out unit 22. That is, the control unit 7 determines whether there is hair between the first blow-out unit 21 and the second blow-out unit 22, and drives the actuator 6 when it is determined that there is hair. The actuator 6 drives at least one of the first blow-out unit 21 and the second blow-out unit 22 based on the instruction from the control unit 7. The actuator 6 can, for example, rotate at least one of the first blow-out unit 21 and the second blow-out unit 22 as described above.

[0026] The presence or absence of hair between the first blow-out part 21 and the second blow-out part 22 can be detected by, for example, the sensor 81. The hair dryer 1 of this embodiment preferably further includes the sensor 81 for detecting the presence or absence of hair between the first blow-out part 21 and the second blow-out part 22, and the control unit 7 drives the actuator 6 based on the detection result of the sensor 81 (see Fig.13 ).

[0027] The sensor 81 is provided on at least one of the first blowing part 21 and the second blowing part 22. The sensor 81 is preferably a photoelectric sensor or a distance sensor. Specifically, as the sensor 81, a transmission type light sensor or a reflection type light sensor is preferably used. The transmission type light sensor, for example, includes a light emitting element (for example, a near infrared LED, etc.) arranged on the side wall on the second blowing part 22 side of the first blowing part 21 and a light receiving element (for example, a photo transistor, etc. that receives the near infrared light emitted by the light emitting element) arranged on the side wall on the first blowing part 21 side of the second blowing part 22. In the case of using a transmission type light sensor, an area including an area irradiated with light before the near infrared light emitted from the light emitting element is received by the light receiving element becomes a detection area. The reflection type light sensor, for example, includes a light emitting element and a light receiving element arranged on either the side wall on the second blowing part 22 side of the first blowing part 21 or the side wall on the first blowing part 21 side of the second blowing part 22. In the case of using a reflection type light sensor, the irradiation range of the light emitted from the light emitting element becomes a detection area. The control unit 7 receives a signal indicating an output voltage (also referred to as an amount of received light) of the light receiving element, and determines the presence or absence of hair between the first blow-out unit 21 and the second blow-out unit 22 .

[0028] In the present disclosure, "the presence or absence of hair between the first blow-out part 21 and the second blow-out part 22" refers to the presence or absence of hair between the opening direction a1 of the first blow-out port 21a and the opening direction a2 of the second blow-out port 22a when the hair dryer 1 is observed from the first direction. Therefore, even if there is actually no hair in the gap between the first blow-out part 21 and the second blow-out part 22, it is possible to determine that there is hair between the first blow-out part 21 and the second blow-out part 22. The determination of the presence or absence of hair by the control part 7 may be a result inferred by the control part 7 based on the result detected by the sensor 81.

[0029] For example, when the control unit 7 operates the hair dryer 1 and supplies air from the first outlet 21a and the second outlet 22a, respectively (see Fig.14A ), the hair h1 may enter between the opening direction a1 (equivalent to the wind direction d1) and the opening direction a2 (equivalent to the wind direction d2). When the control unit 7 determines that the hair h1 exists between the first blow-out section 21 and the second blow-out section 22, the control unit 7 drives the actuator 6. Based on the instruction from the control unit 7, the actuator 6 can, for example, tilt or oppose the opening direction a1 of the first blow-out port 21a to the opening direction a2 of the second blow-out port 22a, thereby rotating at least one of the first blow-out section 21 and the second blow-out section 22 (refer to Fig. 14B ). Fig.14A as well as Fig. 14B This is a schematic diagram showing the relationship between the wind direction d1 and the wind direction d2 when the blowing unit 2 is viewed from the first direction.

[0030] The direction in which the opening direction a1 of the first outlet 21a is inclined relative to the opening direction a2 of the second outlet 22a means that the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a are not parallel. In other words, it means that the angle (absolute value) formed by the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a is greater than 3°. The opening direction a1 of the first outlet 21a is preferably inclined relative to the opening direction a2 of the second outlet 22a when viewed from the first direction.

[0031] The direction in which the opening direction a1 of the first outlet 21a is opposite to the opening direction a2 of the second outlet 22a means that the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a face each other, and the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a are parallel (that is, the angle (absolute value) formed by the opening direction a1 and the opening direction a2 is less than 3°). The opening direction a1 of the first outlet 21a is preferably opposite to the opening direction a2 of the second outlet 22a when viewed from the first direction. In addition, the state in which the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a are parallel is also referred to as a parallel state.

[0032] The state in which the opening direction a1 of the first blowing outlet 21a is inclined or opposite to the opening direction a2 of the second blowing outlet 22a may be any one of (I) a state in which at least one of the first blowing outlet 21a and the second blowing outlet 22a is opened in a direction approaching the other when viewed from the first direction, and (II) a state in which at least one of the first blowing outlet 21a and the second blowing outlet 22a is opened in a direction away from the other when viewed from the first direction. The control unit 7 preferably drives the actuator 6 to achieve the above state (I) or the above state (II). The direction in which the first blowing outlet 21a and the second blowing outlet 22a are close to each other is called inward, and the direction in which the first blowing outlet 21a and the second blowing outlet 22a are away from each other is called outward.

[0033] In the hair dryer 1, when the first blow-out portion 21 and the second blow-out portion 22 are in a position where the above-mentioned state (I) can be achieved, the wind blown out from the first blow-out port 21a and the wind blown out from the second blow-out port 22a are mixed, and the hair can be dried while being clamped by these winds. In addition, when the first blow-out port 21a and the second blow-out port 22a are configured to clamp the hair, the hair can be dried while being clamped by the first blow-out port 21a and the second blow-out port 22a. Therefore, when the user dries the hair, the hair is not easy to spread, and the user can easily adjust the blowing position of the wind. Therefore, by using the hair dryer 1, the user can easily style the hair while drying. In addition, for example, when the user dries the ends of long hair, if the conventional hair dryer is used to blow the wind to the ends of the hair, the ends of the hair will be blown away by the wind, and the wind may not be effectively blown to the ends of the hair. However, the hair dryer 1 can effectively blow the wind to the ends of the hair, so the drying time can be greatly shortened. As described above, the effect of drying the hair while being clamped by a plurality of winds or a plurality of blow-out ports a is also referred to as an effect based on the clamping of the hair.

[0034] In the above state (I), when viewed from the first direction, the acute angle formed by the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a is less than 90°, preferably less than 60°, more preferably less than 45°, and further preferably less than 30°. The lower limit of the acute angle in the above angle is greater than 3°, preferably greater than 5°. In addition, the above acute angle refers to the acute angle of the portion in front of the direction in which the wind is blown out and where the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a intersect.

[0035] In the hair dryer 1, when the first blower 21 and the second blower 22 are in a position to achieve the above-mentioned state (II), the drape phenomenon becomes easy to occur according to the distance between the hair dryer 1 and the hair, and the hair drying time is further shortened. In addition, when the first blower 21 and the second blower 22 are in a position to achieve a parallel state, if the hair dryer 1 is operated, the drape phenomenon becomes easy to occur according to the distance between the hair dryer 1 and the hair, and the hair drying time is further shortened.

[0036] In the above state (II), when viewed from the first direction, the acute angle formed by the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a is less than 90°, preferably less than 60°, more preferably less than 45°, and further preferably less than 30°. The lower limit of the acute angle in the above angle is greater than 3°, preferably greater than 5°. In addition, the above acute angle refers to the acute angle of the portion where the opening direction a1 of the first outlet 21a and the opening direction a2 of the second outlet 22a intersect at the rear side opposite to the wind blowing direction.

[0037] In particular, it is preferable that the first blowing part 21 and the second blowing part 22 be positioned such that at least one of the opening direction a1 of the first blowing outlet 21a and the opening direction a2 of the second blowing outlet 22a is in a direction inclined relative to the third direction when viewed from the first direction. The third direction refers to the normal direction of the plane that uses the first direction and the second direction that is the direction separating the first blowing part 21 from the second blowing part 22 as base vectors. The third direction is typically the front-to-back direction (in Figure 4 It is more preferable that the first blowing part 21 and the second blowing part 22 be positioned such that, when viewed from the first direction, the opening direction a1 of the first blowing outlet 21a is toward the second blowing part 22, and the opening direction a2 of the second blowing outlet 22a is toward the first blowing part 21. In addition, it is further preferable that the first blowing part 21 and the second blowing part 22 be positioned such that at least one of the first blowing outlet 21a and the second blowing outlet 22a opens in a direction away from the centroid when the blowing outlet is viewed from the first direction.

[0038] When the control unit 7 determines that there is hair h1 between the first blowing unit 21 and the second blowing unit 22, the control unit 7 may change the angle of the blowing fin 11 that may be provided in at least one of the first blowing outlet 21a and the second blowing outlet 22a at the same time as the start of the drive of the actuator 6 or before or after the start of the drive of the actuator 6. The control unit 7 may control the electric blower to change the amount of air blown out. The control unit 7 may control the heater to change the temperature of the air blown out. The blowing fin 11, the electric blower, and the heater will be described later.

[0039] If the hair dryer 1 of this embodiment is used, the user can easily style the hair while drying, and can easily achieve a desired hairstyle. In particular, the hair dryer 1 of this embodiment is a device that can dry the hair after shampooing and then perform basic styling. Therefore, the hair dryer 1 of this embodiment can achieve quick drying of hair. In addition, the hair dryer 1 of this embodiment is particularly preferably targeted at long hair. In other words, the hair dryer 1 of this embodiment is particularly preferably a hair dryer for long hair. The hair dryer 1 of this embodiment can also achieve a large air volume with low noise and low vibration.

[0040] Hereinafter, a preferred structure and the like of the hair dryer 1 of the present embodiment will be described in more detail.

[0041] (Blowout part 2) As described above, the first blow outlet 21a and the second blow outlet 22a each have an elongated shape with the first direction as the long side direction. The blow outlet a having an elongated shape means that when the blow outlet a is viewed from the front, the longest length passing through the centroid of the blow outlet a is greater than the shortest length of the blow outlet a. Therefore, when the longest length passing through the centroid of the blow outlet a is La, and the shortest length of the blow outlet a is Sa, the blow outlet a has an elongated shape, which means that the blow outlet a satisfies La>Sa. In addition, the aspect ratio (La / Sa) obtained by dividing the longest length La of the centroid of the blow outlet a by the shortest length Sa of the blow outlet is preferably greater than 3 and less than 20. That is, the aspect ratio (La / Sa) obtained by dividing the longest length La of the centroid of at least one of the first blow outlet 21a and the second blow outlet 22a by the shortest length Sa of the blow outlet is preferably greater than 3 and less than 20. In this way, the effect of efficiently supplying wind to the hair can be more effectively exerted. The aspect ratio of both the first outlet 21a and the second outlet 22a is more preferably 3 or more and 20 or less. The aspect ratio is more preferably 5 or more, and even more preferably 6 or more.

[0042] In addition, the opening width of at least one of the ends of at least one of the first outlet 21a and the second outlet 22a in the first direction is preferably larger than the opening width of the center portion in the first direction. In other words, when at least one of the first outlet 21a and the second outlet 22a is viewed from the front, the opening width L of the front end portion E1 in the first direction is E1 and the opening width L of the base end portion E2 in the first direction E2 At least one of the two is preferably larger than the opening width L of the central portion C in the first direction. C In this case, the wind speed of the wind blown out from the end portion is greater than the wind speed of the wind blown out from the central portion C (see Embodiment 3 described later). The opening width L of both end portions in the first direction E1 and L E2More preferably, it is larger than the opening width L of the central portion in the first direction. C (For example, see Fig. 6A ).

[0043] The end in the first direction refers to the end located on the side opposite to the side where the main body 3 is set, i.e., the front end E1, and the end on the side where the main body 3 is set, i.e., the base end E2, when the outlet a is viewed from the front. (See Figure 6B The central portion C in the first direction refers to the portion including the centroid of the blowout outlet a when the blowout outlet a is viewed from the front (refer to Figure 6B ). Fig. 6A It is used to explain the opening width L of each end E1 and E2 in the first direction of the air outlet a. E1 and L E2 and the opening width L of the central portion C in the first direction C . Figure 6B It is a diagram for explaining the end portions E1 and E2 in the first direction and the center portion C in the first direction in the air outlet a.

[0044] 7A to 7F It is a schematic plan view showing a specific example of the air outlet a. 7A to 7F An example is shown in which the first blow-out port 21a and the second blow-out port 22a are symmetrical with respect to a plane passing through the middle of the first blow-out portion 21 and the second blow-out portion 22 and extending in the first direction, but it goes without saying that the first blow-out port 21a and the second blow-out port 22a of the hair dryer 1 of the present disclosure are not limited to the shapes shown in this example.

[0045] The first outlet 21a and the second outlet 22a preferably have their ends in the first direction spaced apart from each other in a smaller distance than their central portions in the first direction. The distance between the ends in the first direction refers to at least one of a distance L1 between a front end E1 of the first outlet 21a in the first direction and a front end E1 of the second outlet 22a in the first direction, and a distance L2 between a base end E2 of the first outlet 21a in the first direction and a base end E2 of the second outlet 22a in the first direction (see Figure 8 The distance between the central portions in the first direction refers to the distance L3 between the central portion C of the first outlet 21a in the first direction and the central portion C of the second outlet 22a in the first direction (refer to Figure 8 ). It is preferred that L3 is larger than at least one of L1 and L2 (i.e., L1<L3, or L2<L3), and it is more preferred that L3 is larger than L1 and L2 (i.e., L1<L3, and L2<L3). Using such a hair dryer 1, not only can hair be dried more efficiently, but hair styling (also called shaping) can also be made easier. Figure 8: is a diagram for explaining the distances L1 and L2 between the end portions in the first direction and the distance L3 between the central portions in the blowout port a. Figure 8 This is a diagram when the blowing portion 2 is viewed from the front.

[0046] As described above, the first blow-out section 21 and the second blow-out section 22 are spaced apart from each other. Since the first blow-out section 21 and the second blow-out section 22 are spaced apart from each other, it is possible to prevent the air sent from both from immediately merging, so that the drooping phenomenon described later can be effectively generated. Therefore, the hair dryer 1 can effectively supply air to the hair. Between the first blow-out section 21 and the second blow-out section 22 (more precisely, between the first blow-out port 21a and the second blow-out port 22a) is a closed area where no air is sent.

[0047] The draping phenomenon refers to the phenomenon that when air is blown from the hair dryer 1 to the hair, the hair in the area opposite to the hair dryer 1 shows a wave. For example, taking hair drying as an example, when the hair dryer 1 is turned on and air is blown out from the first blow outlet 21a and the second blow outlet 22a, radial high wind speed areas are formed from the first blow outlet 21a and the second blow outlet 22a, respectively. On the other hand, there is a closed area between the first blow outlet 21a and the second blow outlet 22a where no air is blown, but since the air in the closed area is drawn into the high wind speed area, there becomes a low wind speed area between the first blow outlet 21a and the second blow outlet 22a where air flows toward the hair. In this way, when the low speed area is formed in a manner sandwiched by a plurality of high speed areas, the blown air will be turbulent, and turbulent wind like a vortex will be generated in the low wind speed area. When turbulence is generated, the hair is rolled up by the turbulence, and the hair can be dried at a high drying speed. In addition, the wind blown out from the first outlet 21a and the second outlet 22a hits the scalp and then rebounds, generating wind that moves the hair away from the scalp etc. in the low wind speed area, further generating turbulence.

[0048] The hair blown by the air in the high wind speed area is pressed toward the scalp (head) due to the wind pressure. In contrast, the hair in the low wind speed area where turbulence is generated is rolled up by the turbulence and floats away from the scalp (head). As a result, the hair in the area facing the hair dryer 1 is subjected to a phenomenon of waving. In the present disclosure, this phenomenon is referred to as a draping phenomenon. In addition, the wind that generates the high wind speed area and the low wind speed area and that generates the draping phenomenon is also referred to as draping wind.

[0049] The interval between the first blow-out part 21 and the second blow-out part 22 is preferably a distance that can be inserted into the head, hair, hand, etc. In this way, the draping phenomenon can be more effectively generated, and the effect based on the hair clamping described later can also be better exerted. For example, when the first blow-out part 21 and the second blow-out part 22 are arranged to be spaced apart in a direction perpendicular to the first direction, the longest distance between the first blow-out part 21 and the second blow-out part 22 in the perpendicular direction is preferably 10 mm to 100 mm. In addition, it is preferred to adjust the interval between the first blow-out part 21 and the second blow-out part 22, etc., so that the hair can be clamped by the first blow-out port 21a and the second blow-out port 22a.

[0050] The first blow-out part 21 and the second blow-out part 22 are preferably cylindrical parts (also called cylinders) with spaces inside. The cross-section of the cylinder can be any shape such as circular, elliptical, rectangular, polygonal, etc. When the blow-out part 2 is a cylinder, one longitudinal end of the cylinder has an opening for inhaling air from the main body 3, and the opening is connected to the main body blow-out ports 31e and 32e of the main body 3. For example, the first blow-out part 21 is connected to the first main body blow-out port 31e, and the second blow-out part 22 is connected to the second main body blow-out port 32e. The air inhaled from the main body 3 by the first blow-out part 21 and the second blow-out part 22 flows inside the first blow-out part 21 and the second blow-out part 22, respectively, and is blown out to the outside from the first blow-out port 21a and the second blow-out port 22a, respectively.

[0051] The first blowing part 21 and the second blowing part 22 are preferably symmetrical with respect to a plane passing through the middle of the first blowing part 21 and the second blowing part 22 and extending in the first direction. For example, it is preferred that at least one of the outer shape of each blowing part 2, the positional relationship of each blowing part 2, the flow path area inside each blowing part 2, the shape and position of each opening connected to the main body 3, and the shape and position of the blowing outlet a provided in each blowing part 2 is symmetrical with respect to a plane passing through the middle of the first blowing part 21 and the second blowing part 22 and extending in the first direction.

[0052] like Figure 1 and Figure 3 As shown, at least one of the first blow-out portion 21 and the second blow-out portion 22 preferably has a shape with a diameter that decreases toward the front end (also referred to as a front end tapered shape). As a result, since the blow-out portion 2 is easy to insert into the hair, the drying efficiency is further improved when the hair dryer 1 is used, and hair styling is also easier. It is more preferred that both the first blow-out portion 21 and the second blow-out portion 22 have a front end tapered shape. The front end here refers to, for example, the end on the opposite side of one end connected to the main body 3 when the blow-out portion 2 is a cylinder with the first direction as the longitudinal direction.

[0053] For example, Fig. 9B , Fig. 9C and Fig.9D As shown, the shape of the front end t of the first blowing part 21 and the second blowing part 22 is preferably a pointed shape. The pointed shape can be, for example, a shape with a rounded front end (see Fig. 9B ), cone shape (refer to Fig. 9C ) or cone shape (refer to Fig.9D )wait. Fig. 9B , Fig. 9C and Fig.9D 2 is a schematic diagram showing an example in which the shape of the tip end t of the first blowing part 21 and the second blowing part 22 is a pointed shape. Fig. 9A FIG. 2 shows an example in which the tip portions t of the first blowing portion 21 and the second blowing portion 22 are not in a tapered shape. 9A to 9D All of them are pictures when each outlet a is viewed from the front. Figure 1 and Figure 3 In the embodiment, the front ends of the first blowing part 21 and the second blowing part 22 are rounded to make the front ends of these blowing parts have a pointed shape. Figure 1 , Figure 3 and the following FIG. 9B to FIG. 9D Shapes other than those shown.

[0054] At least one of the first outlet 21a and the second outlet 22a may have an outlet fin 11 near the outlet (see Fig.10 The blow-out fin 11 is an air guide component for controlling the flow direction of air or rectifying the flow of air. The blow-out fin 11 can be arranged near each of the first blow-out outlet 21a and the second blow-out outlet 22a, or can be arranged only in one of the first blow-out section 21 and the second blow-out section 22. A plurality of blow-out fins 11 can be arranged in each blow-out outlet a. Fig.10 It is a schematic diagram of the air outlet a provided with the air outlet fin 11.

[0055] The blowing fin 11 may be fixed to the blowing outlet, or the angle of the blowing fin may be manually changed by a user, or the angle may be automatically changed by the control unit 7 .

[0056] By controlling the flow of wind using the blow-out fins 11, the hair dryer 1 can, for example, make the flow direction (referred to as wind direction) of the wind blown out from the first blow-out port 21a and the second blow-out port 22a inward or outward. Therefore, in the hair dryer 1 of this embodiment, if the blow-out port has the blow-out fins 11, the above state (I) or the above state (II) is more easily achieved. The blow-out fins 11 can also make the wind blown out from the first blow-out port 21a and the second blow-out port 22a blow out toward the front end side of the first direction, or toward the base end side of the first direction.

[0057] (Main body 3) In the hair dryer 1 of this embodiment, the first blow-out section 21 and the second blow-out section 22 are attached to the main body 3. Figures 1 to 3 and Figure 5 In the embodiment, the blower 2 and the main body 3 are substantially arranged in a row along the first direction, and the hair dryer 1 as a whole has an I-shaped appearance. In addition, a power supply cable (not shown) is connected to the main body 3 or the grip 4 described later.

[0058] The main body portion 3 is a portion including an air inlet for sucking air from the outside, an electric blower for sending air from the air inlet side to the main body blow-out side, a heater, and a main body blow-out port for sending air to the blow-out portion 2. In the present embodiment, the main body portion 3 has a plurality of main body blow-out ports, and each main body blow-out port is respectively connected to a plurality of blow-out portions 2. Specifically, the first main body blow-out port 31e is connected to the first blow-out portion 21, and the air sucked in by the main body portion 3 is sent to the first blow-out portion 21 via the first main body blow-out port 31e. In addition, the second main body blow-out port 32e is connected to the second blow-out portion 22, and the air sucked in by the main body portion 3 is sent to the second blow-out portion 22 via the second main body blow-out port 32e (refer to Figure 5 ).

[0059] The main body 3 preferably includes a first main body 31 including a first main body blow-out port 31e and a second main body 32 including a second main body blow-out port 32e (see Figure 1 The interior space of the first main body 31 becomes a flow path for the air sucked from the outside to flow to the first main body outlet 31e, and the interior space of the second main body 32 becomes a flow path for the air sucked from the outside to flow to the second main body outlet 32e. In addition, the first main body 31 and the second main body 32 may be arranged to be separated from each other. In this case, the first main body 31 and the second main body 32 may be connected to each other via a supporting member (see Figure 1 ). In addition, the first main body 31 and the second main body 32 may be formed into one main body in appearance, and the main body has a flow path for the air sucked from the outside to flow to the first main body outlet 31e and a flow path for the air sucked from the outside to flow to the second main body outlet 32e. Sometimes the first main body 31 and the second main body 32 are collectively referred to as the main body 3.

[0060] The first main body 31 and the second main body 32 are preferably cylindrical parts with a space inside. The cross section can be any shape such as circular, elliptical, rectangular, polygonal, etc. An opening for supplying air to the blow-out part 2 (i.e., main body blow-out ports 31e, 32e) is formed on the end face of the side connected to the blow-out part 2 in the main body 3, and an opening for sucking air from the outside (i.e., air inlets 31b, 32b) is formed on the end face opposite to the side connected to the blow-out part 2. The air sucked in from the first air inlet 31b and the second air inlet 32b flows inside the first main body 31 and the second main body 32, respectively, and is blown out to the blow-out part 2 from the first main body blow-out port 31e and the second main body blow-out port 32e, respectively.

[0061] The first main body 31 and the second main body 32 respectively include air inlets 31b and 32b for sucking air from the outside, electric blowers 31c and 32c for blowing air from the air inlet side to the main body blow-out side, heaters 31d and 32d, and main body blow-outs 31e and 32e for blowing air to the blow-out part 2 (see Figure 5 ). The first main body 31 and the second main body 32 each have a control substrate (not shown). The control substrate refers to a substrate on which a control unit 7 for controlling the operation of the hair dryer 1 is mounted. The control unit 7, for example, has a chip-shaped control component and a substrate on which the control component is mounted. The control unit 7, for example, controls the actuator 6, the electric blowers 31c and 32c, the heaters 31d and 32d, etc. In the case where the hair dryer 1 has movable blow-out fins 11 or movable air intake fins, the control unit 7 can also control them. The hair dryer 1 may have a control substrate in each of the first main body 31 and the second main body 32, but if Figure 5 As shown, the control substrate may also be provided integrally. Since the control substrate is disposed between the air inlet and the main body outlet, the control substrate is cooled by the air flowing inside the main body 3. The main body 3 further includes an actuator 6.

[0062] The first main body 31 and the second main body 32 are preferably symmetrical with respect to a plane passing through the middle of the first main body 31 and the second main body 32 and extending in the first direction. For example, it is preferred that at least one of the outer shapes and positional relationship of the first main body 31 and the second main body 32, the position or shape of each part of each main body 3, the flow path area inside each blow-out part 3, the shape or position of each main body blow-out port connected to the blow-out part 2, etc., be symmetrical with respect to a plane passing through the middle of the first main body 31 and the second main body 32 and extending in the first direction.

[0063] The positions of the first air inlet 31b in the first body 31 and the second air inlet 32b in the second body 32 may be the same or different. To make the positions of the air sucked in different in the direction in which the flow path extends, the positions of the two may be offset in the first direction, for example.

[0064] The first air inlet 31b and the second air inlet 32b may each have an air inlet fin (not shown) near it. The air inlet fin (also called an air guide component) is an air guide component used to control the flow direction of air or rectify the flow of air. The air inlet fin may be arranged in each of the first air inlet 31b and the second air inlet 32b, or may be arranged in only one of the first air inlet 31b and the second air inlet 32b. Multiple air inlet fins may be arranged in each air inlet.

[0065] The air intake fins may be of a structure that can change the angle (referred to as a movable type). The movable air intake fins may be of a structure that can change the angle automatically by electric means, or of a structure that can change the angle manually by the user. The air intake fins may also be of a structure that cannot change the angle, i.e., fixed (referred to as a fixed type).

[0066] A first electric blower 31c is arranged on the upstream side inside the first main body 31, and a first heater 31d is arranged on the downstream side. A second electric blower 32c is arranged on the upstream side inside the second main body 32, and a first heater 31d is arranged on the downstream side. The upstream side and the downstream side refer to the upstream side and the downstream side in the flow direction of the air, respectively. The air inlet side is the upstream side, and the main body outlet side is the downstream side.

[0067] The position of the first electric blower 31c in the first body 31 and the position of the second electric blower 32c in the second body 32 may be the same or different. If they are arranged at the same position, the hair dryer 1 can easily blow out air with the same wind speed and temperature from the first and second outlets 21a, 22a.

[0068] An electric blower is a general term for a mechanism that uses electricity to blow air. For example, an electric blower may be a mechanism that blows air by using electricity to rotate a component that forms an airflow, such as a fan, or a mechanism that generates an airflow by using electricity to generate vibrations, etc. to form a high-pressure part and a low-pressure part. For example, an electric blower preferably includes a fan and a motor that drives the fan. The arrangement relationship between the fan and the motor in the flow direction is not particularly limited. For example, the fan may be arranged on the upstream side and the motor may be arranged on the downstream side.

[0069] As the motor, for example, a brushless motor, an induction motor, a synchronous reluctance motor, etc. are preferably used. Among them, the motor is more preferably a brushless motor, and more preferably a brushless DC motor.

[0070] Since the brushless motor has no brushes in contact with the rotor, the noise generated by the contact between the brush and the rotor can be suppressed. Therefore, further silencing can be achieved. Brushless motors include, for example, motors in which permanent magnets for excitation are arranged on the rotor side and armature windings are arranged on the stator side, and motors that use sensors for detecting rotor signals (such as Hall sensors, etc.) to feedback to the inverter to control power supply instead of switching power supply based on the position change of the commutator using brushes. The brushless motor can be, for example, a motor that generates a rotating magnetic field to rotate the rotor by changing the direction of the current using switches such as semiconductor switches. In addition, an induction motor can be a motor that generates a sine wave that is phase-shifted from the power supply to rotate the magnetic field. A synchronous reluctance motor is a type of synchronous motor, for example, a motor that rotates as an induction motor at startup and rotates synchronously with the power supply frequency during operation.

[0071] The air flowing in the flow path inside the first main body 31 can be heated by the first heater 31d. The air flowing in the flow path inside the second main body 32 can be heated by the second heater 32d. When the heaters 31d and 32d are in an energized state (referred to as an on state), hot air is blown out from the first blow-out port 21a and the second blow-out portion 22. By setting the heaters 31d and 32d to a non-energized state (referred to as an off state), cold air that is not heated by the heaters 31d and 32d can be blown out from the first blow-out port 21a and the second blow-out portion 22. "Heating" means that the temperature of the gas discharged in the area where the heater is provided is higher than the temperature of the gas (e.g., air) before being guided to the area where the heater is provided.

[0072] The main body 3 has a plurality of electric blowers (electric blowers 31c, 32c) as described above. By providing a plurality of electric blowers, the noise generated when a certain air volume is blown out can be made smaller than the noise when only one electric blower blows out. Thus, the entire hair dryer can be made quieter. In this way, the hair dryer 1 of this embodiment can achieve a large air volume while being quieter.

[0073] A heater and an electric blower are provided in each of the plurality of flow paths provided in the main body 3. Therefore, for example, by making the output (applied power) of each heater and the output (for example, rotation speed) of each electric blower different from each other, air having different temperatures and air volumes can be blown out from the plurality of flow paths. Therefore, for example, even when the hair dryer is kept at a fixed position and a fixed posture, low-temperature air and high-temperature air can be blown alternately to a plurality of adjacent areas, or wind with a large air volume and wind with a small air volume can be blown alternately to a plurality of adjacent areas. In addition, high-temperature air with a large air volume and low-temperature air with a small air volume can be blown alternately to a plurality of adjacent areas, or high-temperature air with a small air volume and wind with a low air volume can be blown alternately to a plurality of adjacent areas. Therefore, for example, quick drying can be improved while preventing hair from being damaged.

[0074] In addition, the electric blowers arranged in each of two adjacent flow paths among the multiple flow paths may rotate in the same direction or in different directions. The rotation directions of the first electric blower 31c and the second electric blower 32c may be controlled to be the same rotation direction or to be opposite rotation directions. For example, the rotation direction of the first electric blower 31c and the rotation direction of the second electric blower 32c may be controlled to alternately appear in periods of the same direction and periods of opposite directions over time. "Direction of rotation" refers to the direction of rotation when observed along the flow path direction of the flow path in which the electric blower is provided. The rotation direction includes clockwise (right-hand rotation) and counterclockwise (left-hand rotation).

[0075] For example, by making the rotation direction of the first electric blower 31c opposite to the rotation direction of the second electric blower 32c, the phase of the sound generated by the first electric blower 31c and the phase of the sound generated by the second electric blower 32c can be made different from each other, or in opposite phase. Therefore, since the sound and vibration generated by each electric blower can be offset, it is possible to further achieve silence, and the hair dryer 1 can be reduced in vibration. In particular, it is preferred that the shape of the fan included in each electric blower arranged in two adjacent flow paths is symmetrical. The two electric blowers can rotate in the same rotation direction as each other, or they can rotate in different rotation directions.

[0076] In the above content, it is explained that an electric blower and a heater are provided in each of the multiple flow paths provided in the main body 3, but it is not limited to this structure. For example, it is preferred to provide an electric blower in at least two of the multiple flow paths. If more than three flow paths are provided, an electric blower may not be provided in at least one of the flow paths. It is preferred to provide an electric blower in two adjacent flow paths among the multiple flow paths. It is not necessary to provide a heater in each of the multiple flow paths. It is preferred to provide a heater in at least two of the multiple flow paths in which an electric blower is provided. However, a heater may not be provided in a part of the flow paths among the at least two flow paths in which an electric blower is provided.

[0077] (Handle 4) The hair dryer 1 of this embodiment may further include a grip portion 4 (see Figure 1 The grip 4 is a portion that the user holds in hand when the hair dryer 1 is in use. In addition, the hair dryer 1 may not include the grip 4, such as a fixed hair dryer.

[0078] The grip 4 is preferably installed at a position close to the centroid of the hair dryer 1 from the viewpoint of reducing the burden on the user. Figures 1 to 3 and Figure 5 In the embodiment, the blow-out portion 2, the main body 3 and the gripping portion 4 are substantially arranged in a row along the first direction. The hair dryer 1 as a whole has an I-shaped appearance. In addition, the gripping portion 4 may also be arranged in a direction inclined relative to the first direction (for example, a direction perpendicular to the first direction).

[0079] The grip 4 is provided with an operating portion (e.g., 41, 42). When the hair dryer 1 is in use, the user operates the operating portion (e.g., the power switch 42, etc.) to start or stop the operation of the hair dryer 1. In addition, the user can adjust the temperature (hot air / cold air), operation mode, air volume, wind direction, etc. of the air blown out from the air outlet a by operating the operating portion (e.g., the operation button 41, etc.).

[0080] Figure 1 The hair dryer 1 shown has a plurality of operation buttons 41 and a power switch 42 as an operation unit, but the hair dryer 1 of this embodiment is not limited to this configuration. For example, the operation unit may include a lever or a circulation lever, etc. If the operation unit includes a lever or a circulation lever, etc., when the direction in which the lever or the circulation lever is slid corresponds to the rotation direction of the blow-out unit 2, the user can easily recognize the rotation direction of the blow-out unit 2 by sight or feeling.

[0081] (Implementation Method 2) In this embodiment, the features unique to this embodiment are mainly described, and the description of the contents repeated in the above embodiment is omitted. The hair dryer 1 of this embodiment is substantially the same as the hair dryer 1 of Embodiment 1, except that the presence or absence of hair between the first blow-out section 21 and the second blow-out section 22 is detected outside the hair dryer 1.

[0082] The hair dryer 1 of this embodiment further includes a communication unit 9 that communicates with an external terminal 10 capable of detecting the presence or absence of hair between the first blow-out unit 21 and the second blow-out unit 22 (see Fig.15 The communication unit 9 may be connected to a communication line via a router, a gateway, etc., and perform unidirectional or bidirectional communication with the external terminal 10 via the communication line, or may directly perform unidirectional or bidirectional communication with the external terminal 10 without using a communication line, for example, via short-range wireless communication such as Bluetooth (registered trademark). The control unit 7 drives the actuator 6 based on the detection result received via the communication unit 9.

[0083] The external terminal 10 can detect whether there is hair between the first blow-out part 21 and the second blow-out part 22. The external terminal 10 is, for example, a device equipped with a camera for photographing hair, specifically a smartphone or a tablet computer. An application for setting the operation of the hair dryer 1 is installed on the external terminal 10. The detection result of the external terminal 10 (for example, an image photographed by the camera) is sent to the control part 7 through the communication part 9. The control part 7 receives this detection result and determines whether there is hair between the first blow-out part 21 and the second blow-out part 22.

[0084] (Implementation 3) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0085] The hair dryer 1 of this embodiment further includes a sensor (also referred to as a length sensor) 82 for measuring the length from a portion of the hair between the first blow-out portion 21 and the second blow-out portion 22 in the direction of hair extension to the front end of the hair (see Fig.16 ). Except for this aspect, it is substantially the same as Implementation 1. Fig.16 1 is a block diagram showing the structure of the hair dryer 1 of this embodiment. The front end of the hair refers to the hair tip. Therefore, the front end side of the hair refers to the hair tip side, and the base end side of the hair refers to the root side of the hair (for example, the scalp in the case of hair) side.

[0086] The length sensor 82 is provided, for example, in at least one of the first blowing section 21 and the second blowing section 22. The sensor 81 described above may be used as the length sensor 82, or a camera for photographing hair may be used as the length sensor 82. The control section 7 receives the measurement value of the length sensor 82 (i.e., the length measured by the length sensor).

[0087] The control unit 7 drives the actuator 6 based on the length acquired from the length sensor 82. For example, the control unit 7 may change the driving method of the actuator 6 according to whether the length (ie, the length to the hair tip) is long or short.

[0088] For example, when the control unit 7 determines that the above-mentioned length is long (for example, more than 10 cm), the control unit 7 can drive the actuator 6 to rotate at least one of the first blow-out portion 21 and the second blow-out portion 22 in the direction of hair extension toward the front end of the hair in such a manner that at least one of the first blow-out port 21a and the second blow-out port 22a opens toward the front end of the hair along the direction of hair extension. The control unit 7 can also change the angle of the blow-out fin 11 so that the blow-out fin 11 is directed toward the front end of the hair along the direction of hair extension. On the other hand, when it is determined that the above-mentioned length is short (for example, less than 10 cm), the actuator 6 can be driven so as to focus on supplying wind to the hair located near the first blow-out portion 21 and the second blow-out portion 22. In addition, when the control unit 7 determines that the above-mentioned length is long or short, the actuator 6 can be not driven, and the opening directions of the first blow-out port 21a and the second blow-out port 22a can be maintained.

[0089] The control unit 7 can also change the wind speed by controlling the actuator 6 and the electric blower based on the length. For example, when the control unit 7 determines that the length is short (e.g., less than 10 cm), the wind speed in the wind direction d1 and the wind speed in the wind direction d2 can be made different. In this case, the hair tip can be curled into a curl shape desired by the user (e.g., an inward curl or an outward curl shape). If the wind speed difference is increased, a stronger curl shape can be formed.

[0090] (Variation of Implementation Example 3) In Embodiment 3, the length sensor 82 is used, but the length may be detected by the external terminal 10 instead of the length sensor 82, and the control unit 7 may receive the detection result via the communication unit 9 (see Embodiment 2). Alternatively, the user may input the length of the hair in advance in the external terminal or the operation unit of the hair dryer 1, and the control unit 7 may determine the length using the input length and, for example, the detection result from the sensor 81 or the external terminal 10.

[0091] (Implementation 4) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0092] In the hair dryer 1 of this embodiment, the control unit 7 drives the actuator 6 based on whether there is hair h1 between the first blow-out portion 21 and the second blow-out portion 22, so as to blow air from the first blow-out port 21a and the second blow-out port 22a in a direction oblique to the extension direction of the hair h1, so as to be close to the hair h1 and toward the front end side of the hair h1 relative to the hair h1 between the opening direction a1 of the first blow-out port 21a and the opening direction a2 of the second blow-out port 22a. Except for this aspect, it is substantially the same as the first, second or third embodiment. Such control by the control unit 7 is called the first drying control. In addition, the drying process controlled in this way is called the first drying process.

[0093] In the first drying process, since the posture of the hair is stable during drying, the above-mentioned effect of the hair clamping can be more fully exerted. The front end side of the hair refers to the hair tip side, and the base end side of the hair refers to the root side of the hair (for example, the scalp side in the case of hair). The wind direction is oblique to the hair extension direction, which means that the wind direction is oblique to the hair extension direction (for example, the scalp side). Fig.11 and Fig.12 The middle is tilted in the up and down direction).

[0094] For example, Fig.12 As shown, when the hair dryer 1 takes a plurality of hairs h1 at the back of the head as drying objects, in the first drying process, the control unit 7 drives the actuator 6 and the like to blow the wind of the wind direction d1 toward the ends of the hairs h1 and close to the hairs h1 from the first blowing outlet 21a located on the first side S1 of the two sides (i.e., the first side S1 and the second side S2) clamping the hairs h1, and blow the wind of the wind direction d2 toward the ends of the hairs h1 and close to the hairs h1 from the second blowing outlet 22a located on the second side S2. The wind directions d1 and d2 are respectively oblique directions with respect to the extension direction h0 of the hairs h1. In the first drying process, the hairs h1 can be clamped by the wind of the wind direction d1 and the wind of the wind direction d2. Fig.12 Schematic diagram of the wind direction d1 and the wind direction d2 blown to the hair (hair h1) in the first drying control. Fig.12 This is a diagram when the hair h1 is viewed toward the back of the head. h0 in the diagram is the direction in which the hair h1 at the back of the head extends.

[0095] (Implementation method 5) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0096] In the hair dryer 1 of this embodiment, after the control unit 7 performs the first drying control, it drives the actuator 6 to perform the second drying control for supplying air from the first outlet 21a and the second outlet 22a. The hair dryer 1 of this embodiment is substantially the same as the embodiment 4 except for this point. In addition, the drying process controlled by the second drying control is called the second drying process.

[0097] After performing the first drying control, the control unit 7 switches to the second drying control based on, for example, a user's instruction, elapsed time, or an input from a sensor.

[0098] In these cases, as an example of the control unit 7 switching to the second drying control based on the elapsed time, for example, after the control unit 7 performs the first drying control, when the predetermined drying time has elapsed, the control unit 7 switches to the second drying control. The predetermined drying time is, for example, a drying time input in advance by the user (for example, a drying time input by the user to the operation unit or the external terminal); a drying time predicted by the control unit 7 based on hair data such as the length and amount of hair; a drying time calculated by the control unit 7 or the like through machine learning to switch the timing, etc. The above-mentioned hair data may be data input in advance by the user on the operation unit or the external terminal, or data calculated from an image captured by a camera, for example.

[0099] Examples of the control unit 7 switching to the second drying control based on the input from the sensor include the following examples: for example, a temperature sensor is provided in at least one of the first blowing unit 21 and the second blowing unit 22, and the surface temperature of the hair is detected by the temperature sensor, and the control unit 7 switches to the second drying control based on the detected value; a humidity sensor is provided in at least one of the first blowing unit 21 and the second blowing unit 22, and the dryness of the hair is detected by the humidity sensor, and the control unit 7 switches to the second drying control based on the detected value; a camera is provided in at least one of the first blowing unit 21 and the second blowing unit 22, and the degree of hair tangling (for example, anti-hair bundle index) is detected by the camera, and the control unit 7 switches to the second drying control based on the detected result. Among them, for example, in the example in which the control unit 7 switches to the second drying control based on the detected value of the surface temperature of the hair, when the surface temperature of the hair is obtained from the temperature sensor over time and it is determined that the surface temperature is lower than (or higher than) a threshold value, the control unit 7 can switch from the first drying control to the second drying control. The threshold value can be set in advance.

[0100] As described above, the first drying control dries the hair by clamping it with wind blowing from both sides of the hair h1 (i.e., the first side S1 and the second side S2). That is, the first drying control can mainly dry the part sandwiched by the two winds, while the second drying control is not limited to the part and can dry the entire hair (e.g., the entire head). If the first drying control and the second drying control are performed, the drying efficiency will be further improved.

[0101] In the second drying control, the control unit 7 can control the opening direction a1 of the first blowing outlet 21a and the opening direction a2 of the second blowing outlet 22a through the actuator 6 without any particular limitation. For example, the control unit 7 can drive the actuator 6 so that when viewed from the first direction, at least one of the first blowing outlet 21a and the second blowing outlet 22a opens in a direction away from the other (i.e., the above-mentioned state (II) is achieved). In addition, the control unit 7 can drive the actuator 6 so that when viewed from the first direction, the opening direction a1 of the first blowing outlet 21a is parallel to the opening direction a2 of the second blowing outlet 22a. The control unit 7 can also drive the actuator 6 over time to change at least one of the opening directions a1 of the first blowing outlet 21a and the opening direction a2 of the second blowing outlet 22a over time.

[0102] (Variation of Implementation Example 5) In the hair dryer 1 of the fifth embodiment, the control unit 7 performs the second drying control after performing the first drying control, but the control unit 7 may perform the first drying control after performing the second drying control. After performing the second drying control, the control unit 7 switches to the first drying control based on, for example, a user's instruction, elapsed time, or an input from a sensor.

[0103] (Implementation method 6) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0104] In the hair dryer 1 of the present embodiment, in the second drying control, the control unit 7 drives the actuator 6 so that the air is blown out from the first blow outlet 21a toward the front end side of the hair in an oblique direction inclined to the extension direction of the hair, and the air is blown out from the second blow outlet 22a toward the base end side of the hair in an oblique direction inclined to the extension direction of the hair. In this case, since the air is blown out in different directions from the plurality of blow outlets, the hair can be prevented from being bunched, and the drying efficiency can be further improved. The hair dryer 1 of the present embodiment is substantially the same as the fifth embodiment except for this aspect.

[0105] For example, Fig.12As shown in the figure, when the hair dryer 1 takes a plurality of hairs h1 at the back of the head as drying objects, the control unit 7 drives the actuator 6 and the like so that the hair is blown out from the first blow outlet 21a located at the first side S1 toward the front end side of the hairs h1 (at Fig.12 The wind of the wind direction d1 close to the hair h1 is blown from the second blow outlet 22a located on the second side S2 toward the base end side of the hair h1 (at the bottom of the hair h1). Fig.12 The wind direction d1 and the wind direction d2 are oblique directions with respect to the extension direction h0 of the hair h1. Fig.12 Schematic diagram of the wind direction d1 and the wind direction d2 blowing toward the hair (hair h1) during one period T21 of the second drying step. Fig.12 This is a diagram when the hair h1 is viewed toward the back of the head.

[0106] In the second drying control, the control unit 7 drives the actuator 6 so that air can be blown out from the first blowing outlet 21a in an oblique direction toward the base end side of the hair in the direction of hair extension, and it is also preferred that air can be blown out from the second blowing outlet 22a in an oblique direction toward the front end side of the hair in the direction of hair extension (for example, refer to embodiment 7 described later).

[0107] (Implementation 7) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0108] In the hair dryer 1 of the present embodiment, in the second drying control, the control unit 7 drives the actuator 6 so that the period T21 and the period T22 are repeated alternately. In the period T21, the air is blown out from the first blow outlet 21a toward the front end side of the hair in an oblique direction inclined to the extension direction of the hair, and the air is blown out from the second blow outlet 22a toward the base end side of the hair in an oblique direction inclined to the extension direction of the hair. In the period T22, the air is blown out from the first blow outlet 21a toward the base end side of the hair in an oblique direction inclined to the extension direction of the hair, and the air is blown out from the second blow outlet 22a toward the front end side of the hair in an oblique direction inclined to the extension direction of the hair. The hair dryer 1 of the present embodiment is substantially the same as the embodiment 6 except for this point. The period T21 and the period T22 are repeated alternately, so that the drying time can be further shortened.

[0109] For example, when the blowing part 2 of the first blowing outlet 21a and the second blowing outlet 22a can rotate along the first direction, if the control unit 7 rotates the blowing part 2 in one direction through the actuator 6, the wind directions d1 and d2 of the wind blown out from the first blowing outlet 21a and the second blowing outlet 22a are in the following order: Fig.17AIf the control unit 7 further rotates the blower 2 in the other direction through the actuator 6, the wind directions d1 and d2 of the wind blown out from the first blower outlet 21a and the second blower outlet 22a will be as follows: Fig. 17B By repeatedly rotating the blow-out portion 2, the blow-out portion 2 is in the state shown in FIG. Fig.17A The period T1 of the state shown is the same as that of Fig. 17B The period T2 of the state shown is repeated alternately. In addition, the control unit 7 can rotate the blower 2 in a direction inclined to the first direction (for example, a direction perpendicular to the first direction) while rotating the blower 2 in the first direction through the actuator 6. In this case, since the hair dryer 1 can supply wind from more directions to the hair, the drying time can be further shortened. Fig.17A and Fig. 17B It is a schematic diagram which shows the operation|movement of the blowing part 2 in this embodiment.

[0110] (Variation of Implementation Example 7) In the hair dryer 1 of the seventh embodiment, the control unit 7 drives the actuator 6 in the second drying control so that the period T1 and the period T2 are repeated alternately. However, when the hair dryer 1 is provided with a movable blowing fin 11, the control unit 7 may control the angle of the movable blowing fin 11 in the second drying control so that the period T1 and the period T2 are repeated alternately. When the hair dryer 1 is provided with a movable blowing fin 11, the control unit 7 may control the actuator 6 and the movable blowing fin 11 simultaneously in the second drying control so that the period T1 and the period T2 are repeated alternately.

[0111] (Implementation 8) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0112] In the hair dryer 1 of this embodiment, after the control unit 7 performs the second drying control, the actuator 6 is driven to blow air from the first blow outlet 21a and the second blow outlet 22a, respectively, toward the front end side of the hair in an oblique direction that is inclined to the extension direction of the hair. Except for this aspect, it is substantially the same as the fifth, sixth or seventh embodiment. As described above, the second drying process is a process of drying the entire hair, and the above control is performed after this process to make the hair neat.

[0113] After performing the second drying control, the control unit 7 drives the actuator 6 to supply air as described above, for example, based on an instruction from a user, elapsed time, or input from a sensor.

[0114] (Variation of Implementation Example 8) In the hair dryer 1 of the eighth embodiment, the control unit 7 drives the actuator 6 after performing the second drying control. However, if the hair dryer 1 is provided with a movable blowing fin 11, the control unit 7 may control the angle of the movable blowing fin 11 after performing the second drying control so that air is blown out from each of the first blowing outlet 21a and the second blowing outlet 22a toward the front end side of the hair in an oblique direction inclined to the hair extension direction. If the hair dryer 1 is provided with a movable blowing fin 11, the control unit 7 may control both the actuator 6 and the movable blowing fin 11 after performing the second drying control so that air is blown out from each of the first blowing outlet 21a and the second blowing outlet 22a toward the front end side of the hair in an oblique direction inclined to the hair extension direction.

[0115] (Implementation method 9) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0116] In the hair dryer 1 of the present embodiment, the control unit 7 performs the third drying control after performing the first drying control. In the third drying control, when the first blowing outlet 21a and the second blowing outlet 22a move from the base end side to the front end side of the hair, the actuator 6 is driven to adjust the opening direction of at least one of the first blowing outlet 21a and the second blowing outlet 22a. The hair dryer 1 of the present embodiment is substantially the same as the fourth, fifth, sixth, seventh or eighth embodiment except for this point. In addition, the drying process controlled by the third drying control is referred to as the third drying process.

[0117] In the third drying control, when the first blow outlet 21a and the second blow outlet 22a move from the base end side to the front end side of the hair, the control unit 7 drives the actuator 6 to adjust the opening direction of at least one of the first blow outlet 21a and the second blow outlet 22a so that the blow outlet a has an appropriate opening direction. For example, in the first drying process, when the control unit 7 detects that the user starts to slide the hair dryer 1 toward the front end side (hair end side), the control unit 7 can drive the actuator 6 to change the opening direction of the first blow outlet 21a and the second blow outlet 22a to a direction suitable for sliding the hair dryer 1 (for example, so that the wind direction is toward the hair end). The control unit 7 can also detect the position where the wind blows (for example, the middle part of the hair or the hair end, etc.) when the user starts to slide the hair dryer 1 or during the sliding process, and drive the actuator 6 to change the opening direction of the first blow outlet 21a and the second blow outlet 22a to an appropriate direction suitable for the position.

[0118] For example, Fig.11As shown, when the hair h1 at the back of the head is taken as the drying object, for example, when the wind in the wind direction d1 is blown from the first blowing outlet 21a located on the first side S1 of the two sides (i.e., the first side S1 and the second side S2) clamping the hair h1, and the wind in the wind direction d2 is blown from the second blowing outlet 22a located on the second side S2 to the hair h1, the user may blow the first blowing part 21 having the first blowing outlet 21a and the second blowing part 22 having the second blowing outlet 22a from the root of the hair h1 to the tip of the hair (i.e., in the direction of the first side S1 and the second side S2). Fig.11 That is, the user may slide the hair dryer 1 having the first blow-out portion 21 and the second blow-out portion 22 along the extension direction h0 of the hair h1 in a state where the wind in the wind direction d1 and the wind in the wind direction d2 hold the hair (particularly preferably, in a state where the first blow-out portion 21a and the second blow-out portion 22a hold the hair). When the control unit 7 detects that the user slides the hair dryer 1 in this way, the control unit 7 can drive the actuator 6 to change the opening direction of the first blow-out portion 21a and the second blow-out portion 22a to a direction suitable for sliding the hair dryer 1. The control unit 7 can also detect the position where the wind blows and drive the actuator 6 to change the opening direction of the first blow-out portion 21a and the second blow-out portion 22a to an appropriate direction suitable for the position.

[0119] By performing the third drying control, the user can more easily style the hair while drying. In particular, the user can style the hair of the part blown by the wind into straight hair. Therefore, the hair dryer 1 of this embodiment is very excellent in the styling property of easily achieving the desired style.

[0120] (Variation of Implementation Example 9) In the third drying control, the control unit 7 drives the actuator 6 to adjust the opening direction of at least one of the first blow-out port 21a and the second blow-out port 22a. However, if the hair dryer 1 includes the movable blow-out fin 11, after performing the first drying control, when the first blow-out port 21a and the second blow-out port 22a move from the base end side of the hair to the front end side, the control unit 7 may control the angle of the movable blow-out fin 11 to adjust the opening direction of at least one of the first blow-out port 21a and the second blow-out port 22a. If the hair dryer 1 includes the movable blow-out fin 11, after performing the first drying control, when the first blow-out port 21a and the second blow-out port 22a move from the base end side of the hair to the front end side, the control unit 7 may simultaneously control both the actuator 6 and the movable blow-out fin 11 to adjust the opening direction of at least one of the first blow-out port 21a and the second blow-out port 22a.

[0121] (Implementation 10) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted.

[0122] The hair dryer 1 of this embodiment further includes a detection unit 83 for detecting the amount of moisture attached to the hair surface (see Fig.18 ). Except for this aspect, it is substantially the same as embodiment 1, 2, 3, 4, 5, 6, 7, 8 or 9.

[0123] The detection unit 83 detects the amount of moisture attached to the hair surface (referred to as the amount of moisture attached to the hair surface). For example, as the detection unit 83, a photoelectric sensor (e.g., a transmission type light sensor, a reflection type light sensor, etc.) can be used to calculate the amount of moisture attached using the absorption wavelength of water. Alternatively, a member having a pair of electrodes as the detection unit 83 can be provided on the mutually facing sides of the first blow-out unit 21 and the second blow-out unit, and the amount of moisture attached can be calculated from the conductivity by measuring the conductivity. Alternatively, a camera for photographing hair can be used as the detection unit 83. A humidity sensor can also be used as the detection unit 83. Furthermore, the above-mentioned sensor 81 or length sensor 82 can also be used as the detection unit 83. The detection unit 83 outputs the detection result to the control unit 7, and the control unit 7 receives the detection result.

[0124] The control unit 7 drives the actuator 6 based on the detection result (i.e., the amount of moisture on the hair surface) obtained from the detection unit 83. For example, the control unit 7 can change the driving method of the actuator 6 according to the amount of moisture on the hair in the detection area of ​​the detection unit 83.

[0125] For example, when the control unit 7 determines that the amount of moisture adhering to the hair surface near the first blowing unit 21 and the second blowing unit 22 is large (for example, the amount of adsorbed moisture relative to the weight of the hair is 5% or more), the control unit 7 can drive the actuator 6 to rotate at least one of the first blowing unit 21 and the second blowing unit 22 so as to focus on supplying wind to the hair near the first blowing unit 21 and the second blowing unit 22 (see FIG. Fig.19A On the other hand, when it is determined that the amount of moisture attached to the hair surface in the vicinity is small (for example, the amount of moisture adsorbed relative to the weight of the hair is less than 5%), the control unit 7 can drive the actuator 6 to rotate at least one of the first blowing unit 21 and the second blowing unit 22 so as to supply air to the hair other than the vicinity (see Fig.19B ). In addition, when the control unit 7 determines that the amount of moisture attached to the hair surface is large or small, the actuator 6 may not be driven, and the opening directions of the first outlet 21a and the second outlet 22a may be maintained. Fig.19A and Fig.19B It is a schematic diagram which shows the operation|movement of the blowing part 2 in this embodiment.

[0126] The control unit 7 may further change the air volume or air temperature by controlling at least one of the electric blower and the heater based on the amount of moisture attached to the hair surface.

[0127] (Variation of Implementation Example 10) In the second embodiment, the detection unit 83 is used. However, instead of the detection unit 83, the external terminal 10 may detect the amount of moisture attached to the hair surface, and the control unit 7 may receive the detection result via the communication unit 9 (see the second embodiment).

[0128] The embodiments of the present disclosure are described above, but the present disclosure is not limited to the above embodiments and can be implemented in various ways without departing from the scope of the present invention. In addition, the multiple components disclosed in the above embodiments can be appropriately changed. For example, a component of all the components shown in a certain embodiment can be added to the components of another embodiment, or some of the components of all the components shown in a certain embodiment can be deleted from the embodiment.

[0129] In addition, in the drawings, for easy understanding, each component is schematically shown as a main body, and for the convenience of drawing, the thickness, length, number, spacing, etc. of each component shown in the drawings may be different from the actual one. In addition, the configuration of each component shown in the above embodiment is only an example and is not particularly limited. Of course, various changes can be made within the scope that does not substantially deviate from the effect of the present invention. Description of Reference Numerals
