[0008] Hereinafter, an embodiment of a hair dryer according to the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the contents described in the following embodiment, and appropriate design changes can be made within the scope of the configuration of the present disclosure. In the drawings, the same or equivalent elements are given the same reference numerals, and duplicated explanations will be omitted.

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

[0010] The terms "flow direction" and "flow path direction" each refer to the direction in which wind flows on a virtual line connecting the centers of the flow paths. The center of the flow path refers to the centroid of the inner shape of the cross section of the flow path. The terms "flow direction" and "flow path direction" each may be a direction that extends in a straight line, or, for example, when the flow path has a curved or bent portion, may be a direction that extends partially or entirely along a curved or bent virtual line. In such cases, the terms "flow direction" and "flow path direction" each may be composed of different vectors at different locations in the direction in which the virtual line connecting the centers of the flow paths (this virtual line is also called the "flow path centerline") extends.

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

[0012] (Embodiment 1) Fig. 1 to Fig. 4 are schematic diagrams illustrating the appearance of the hair dryer 1 of the present embodiment. Of these, Fig. 1 is a front view, Fig. 2 is a right side view, Fig. 3 is a rear view, and Fig. 4 is a top view. Fig. 5 is a schematic cross-sectional view illustrating the internal configuration of the hair dryer 1 of the present embodiment. As will be described later, the up-down direction in Fig. 1 to Fig. 3 and Fig. 5 corresponds to a first direction.

[0013] The hair dryer 1 includes, as its main components, a plurality of blowing sections 2. The plurality of blowing sections 2 include a first blowing section 21 and a second blowing section 22. The hair dryer 1 further includes a main body section 3 to which the first blowing section 21 and the second blowing section 22 are attached. The first blowing section 21 and the second blowing section 22 may be collectively referred to as the blowing section 2.

[0014] (Blowout section 2) The first blowing section 21 includes a first blowing outlet 21a formed in an elongated shape along the first direction. The second blowing section 22 includes a second blowing outlet 22a formed in an elongated shape along the first direction. The first blowing outlet 21a and the second blowing outlet 22a are openings through which the first blowing section 21 and the second blowing section 22 blow out the air taken in from the main body section 3 to the outside. The internal space of the first blowing section 21 serves as a flow path through which the air taken in from the main body section 3 flows to the first blowing outlet 21a, and the internal space of the second blowing section 22 serves as a flow path through which the air taken in from the main body section 3 flows to the second blowing outlet 22a. These flow paths are parallel to each other and preferably have the same flow path area. In other words, the first blowing section 21 and the second blowing section 22 preferably have the same cross-sectional area at the same position in the flow direction of the internal space. The first blowing outlet 21a and the second blowing outlet 22a may be collectively referred to as a blowing outlet a.

[0015] Each of the first air outlet 21a and the second air outlet 22a has an elongated shape with the first direction as its longitudinal direction. In the present disclosure, the longitudinal direction of the first air outlet 21a and the second air outlet 22a (corresponding to the up-down direction in Figs. 1 to 3 and 5) is defined as the first direction. Air (also referred to as wind) is blown out from the first air outlet 21a in a second direction inclined with respect to the first direction, and air is blown out from the second air outlet 22a in the second direction inclined with respect to the first direction. The second direction is typically a direction perpendicular to the first direction (for example, the left direction in Fig. 2). It is preferable that the first direction is a direction along the hair growth direction.

[0016] The wording "elongated" means that the longest length passing through the centroid of the outlet a is greater than the shortest length of the outlet a when the outlet a is viewed from the front. Therefore, when the longest length passing through the centroid of the outlet a is La and the shortest length of the outlet a is Sa, the wording "elongated" means that the outlet a satisfies La>Sa. In addition, the aspect ratio (La / Sa) obtained by dividing the longest length La passing through the centroid of the outlet a by the shortest length Sa of the outlet is preferably 3 or more and 20 or less. That is, the aspect ratio (La / Sa) obtained by dividing the longest length La passing through the centroid of at least one of the first outlet 21a and the second outlet 22a by the shortest length Sa of the outlet is preferably 3 or more and 20 or less. This makes it possible to more effectively supply air to hair. It is more preferable that the aspect ratios of both the first outlet 21a and the second outlet 22a are 3 or more and 20 or less. The aspect ratio is more preferably 5 or more, and further preferably 6 or more.

[0017] In addition, it is preferable that the opening width of at least one of the ends in the first direction of at least one of the first air outlet 21a and the second air outlet 22a is larger than the opening width of the center in the first direction. In other words, when at least one of the first air outlet 21a and the second air outlet 22a is viewed from the front, the opening width L E1 and the opening width L of the base end E2 in the first direction E2At least one of the opening width L of the central portion C in the first direction C In this case, the speed of the wind blown out from the end portion C is greater than the speed of the wind blown out from the center portion C (see the third embodiment described later). E1 and L E2 The opening width L at the center in the first direction C It is more preferable that the axial length of the slit is larger than 100 mm (see, for example, FIG. 6A).

[0018] The ends in the first direction refer to the tip end E1, which is the end opposite to the side where the main body 3 is arranged, when the air outlet a is viewed from the front, and the base end E2, which is the end on the side where the main body 3 is arranged, when the air outlet a is viewed from the front (see FIG. 6B). The center C in the first direction refers to the part including the centroid of the air outlet a, when the air outlet a is viewed from the front (see FIG. 6B). FIG. 6A shows the opening widths L of the ends 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 6B is a diagram for explaining ends E1 and E2 in the first direction and a central portion C in the first direction of the air outlet a.

[0019] 7A to 7F are schematic plan views showing specific examples of the air outlet a. Although Fig. 7A to Fig. 7F show examples in which the first air outlet 21a and the second air outlet 22a are symmetrical with respect to a plane extending in the first direction passing through the middle between the first air outlet section 21 and the second air outlet section 22, it goes without saying that the first air outlet 21a and the second air outlet 22a of the hair dryer 1 of the present disclosure are not limited to the shapes shown in these examples.

[0020] It is preferable that the distance between the central portions in the first direction is larger than the distance between the end portions in the first direction for the first air outlet 21a and the second air outlet 22a. The distance between the end portions in the first direction means at least one of the distance L1 between the tip end portion E1 in the first direction of the first air outlet 21a and the tip end portion E1 in the first direction of the second air outlet 22a, and the distance L2 between the base end portion E2 in the first direction of the first air outlet 21a and the base end portion E2 in the first direction of the second air outlet 22a (see FIG. 8). The distance between the central portions in the first direction means the distance L3 between the central portion C in the first direction of the first air outlet 21a and the central portion C in the first direction of the second air outlet 22a (see FIG. 8). It is preferable that L3 is larger than at least one of L1 and L2 (that is, L1 < L3, or L2 < L3), and it is more preferable that L3 is larger than L1 and L2 (that is, L1 < L3 and L2 < L3). By using such a hair dryer 1, the hair can be dried more efficiently, and styling (also referred to as setting) of the hair becomes easier. FIG. 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 at the air outlet a. Note that FIG. 8 is a diagram when the blowing portion 2 is viewed from the front.

[0021] The first blowing portion 21 and the second blowing portion 22 are arranged to be separated from each other. For example, it is preferable that the first blowing portion 21 and the second blowing portion 22 are arranged to be separated from each other along a second direction inclined with respect to the first direction. The second direction is typically a direction perpendicular to the first direction (corresponding to the left - right direction in FIGS. 1 to 3 and FIG. 5). Also, it is preferable that the first blowing portion 21 and the second blowing portion 22 are arranged in parallel. For example, as in the hair dryer 1 shown in FIG. 1, it is preferable that the first blowing portion 21 and the second blowing portion 22 are arranged in parallel along the first direction and are separated from each other along a direction perpendicular to the first direction.

[0022] By arranging the first blowing section 21 and the second blowing section 22 apart from each other, the airflows blown out from both the sections are prevented from immediately joining together, and thus the drape phenomenon described below occurs effectively. This makes it possible to efficiently supply airflow to hair from the hair dryer 1. The area between the first blowing section 21 and the second blowing section 22 (more precisely, between the first blowing outlet 21a and the second blowing outlet 22a) is a closed area from which airflow is not blown out.

[0023] The drape phenomenon is a phenomenon in which hair wavy in an area facing the hair dryer 1 when air is blown from the hair dryer 1 to the hair. For example, in the case of drying hair, when the hair dryer 1 is started and air is blown out from the first air outlet 21a and the second air outlet 22a, high air velocity areas are formed radially from the first air outlet 21a and the second air outlet 22a. On the other hand, a closed area where air is not blown out is formed between the first air outlet 21a and the second air outlet 22a, but the air in this closed area is caught in the high air velocity area, and a low air velocity area where air flows toward the hair is formed between the first air outlet 21a and the second air outlet 22a. When a low air velocity area is formed between a plurality of high air velocity areas in this way, turbulence occurs in the blown air, and a swirling turbulent flow of air is generated in the low air velocity area. When the turbulent flow occurs, the hair is rolled up by the turbulent flow, and the hair can be dried at a high drying speed. In addition, the wind blown out from the first air outlet 21a and the second air outlet 22a hits the scalp and bounces back, generating wind in the low wind speed area that separates the hair from the scalp, etc., and further generating turbulence.

[0024] The hair exposed to the air in the high wind speed region is pressed against the scalp (head) by the wind pressure. In contrast, the hair in the low wind speed region where turbulence is generated is rolled up by the turbulence and lifted away from the scalp (head). As a result, a phenomenon occurs in which the hair wavy in the region facing the hair dryer 1. In the present disclosure, such a phenomenon is referred to as the draping phenomenon. The wind that creates the high wind speed region and the low wind speed region, which causes the draping phenomenon, is also referred to as the draping wind.

[0025] The distance between the first blowing section 21 and the second blowing section 22 is preferably a distance that allows the head, hair, hands, etc. to be inserted between the first blowing section 21 and the second blowing section 22. This allows the drape phenomenon to occur more effectively, and also allows the effect of pinching hair, which will be described later, to be more effectively achieved. For example, when the first blowing section 21 and the second blowing section 22 are arranged apart along a direction perpendicular to the first direction, the above-mentioned distance is preferably 10 mm to 100 mm, the longest distance between the first blowing section 21 and the second blowing section 22 in the perpendicular direction. In addition, it is preferable to adjust the distance between the first blowing section 21 and the second blowing section 22, etc., so that hair can be pinched between the first blowing outlet 21a and the second blowing outlet 22a.

[0026] The first blowing section 21 and the second blowing section 22 are preferably cylindrical members (also referred to as cylinders) with a space inside. The cross section of the cylinder may be any of a circular, elliptical, oval, polygonal, and the like. When the blowing section 2 is a cylinder, one end in the longitudinal direction of the cylinder has an opening for taking in air from the main body section 3, and this opening is connected to the main body blowing outlets 31e and 32e of the main body section 3. For example, the first blowing section 21 is connected to the first main body blowing outlet 31e, and the second blowing section 22 is connected to the second main body blowing outlet 32e. The air taken in from the main body section 3 by the first blowing section 21 and the second blowing section 22 flows inside the first blowing section 21 and the second blowing section 22, respectively, and is blown out to the outside from the first blowing outlet 21a and the second blowing outlet 22a, respectively.

[0027] It is preferable that the first blowing section 21 and the second blowing section 22 are symmetrical with respect to a plane extending in the first direction that passes between the first blowing section 21 and the second blowing section 22. For example, it is preferable that one or more of the outer shape of each blowing section 2, the positional relationship of each blowing section 2, the flow path area inside each blowing section 2, the shape and position of each opening connected to the main body section 3, and the shape and position of the blowing port a provided in each blowing section 2 are symmetrical with respect to a plane extending in the first direction that passes between the first blowing section 21 and the second blowing section 22.

[0028] As shown in Fig. 1 and Fig. 3, it is preferable that at least one of the first blowing section 21 and the second blowing section 22 has a shape in which the diameter becomes smaller toward the tip (also referred to as a tapered shape). This makes it easier to insert the blowing section 2 into the hair, so that when the hair dryer 1 is used, the drying efficiency is improved and hair styling becomes easier. It is more preferable that both the first blowing section 21 and the second blowing section 22 have a tapered shape. The tip means the end opposite to the end connected to the main body section 3 when the blowing section 2 is a cylinder whose longitudinal direction is the first direction, for example.

[0029] For example, as shown in Fig. 9B, Fig. 9C, and Fig. 9D, the shape of the tip t of the first blowing section 21 and the second blowing section 22 is preferably tapered. The tapered shape is, for example, a shape with a rounded tip (see Fig. 9B), a cone shape (see Fig. 9C), or a cone body shape (see Fig. 9D). Fig. 9B, Fig. 9C, and Fig. 9D are schematic diagrams showing an example in which the tip t of the first blowing section 21 and the second blowing section 22 is tapered. For reference, Fig. 9A shows an example in which the tip t of the first blowing section 21 and the second blowing section 22 is not tapered. Figs. 9A to 9D are all diagrams showing each blowing port a as viewed from the front. Note that in Fig. 1 and Fig. 3, the tip portions of the first blowing section 21 and the second blowing section 22 are chamfered to form the tips of these blowing sections into a tapered shape. The tapered shape may be a shape other than the shapes shown in FIGS. 1, 3, and 9B to 9D.

[0030] (Opening direction) The first blowing section 21 and the second blowing section 22 may be positioned such that the opening direction a1 of the first blowing outlet 21a is inclined or opposed to the opening direction a2 of the second blowing outlet 22a. In other words, the first blowing section 21 and the second blowing section 22 may be positioned such that the opening direction a1 of the first blowing outlet 21a is inclined to the opening direction a2 of the second blowing outlet 22a or opposed to the opening direction a2 of the second blowing outlet 22a.

[0031] The opening direction of the air outlet a means the direction in which the centroid of the air outlet a faces, and essentially corresponds to the direction of air flow (wind direction) in the vicinity of the air outlet a.

[0032] The opening direction a1 of the first air outlet 21a being inclined with respect to the opening direction a2 of the second air outlet 22a means that the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a are not parallel. That is, the angle (absolute value) between the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a is more than 3°. It is preferable that the opening direction a1 of the first air outlet 21a is inclined with respect to the opening direction a2 of the second air outlet 22a when viewed from the first direction.

[0033] The opening direction a1 of the first air outlet 21a being a direction facing the opening direction a2 of the second air outlet 22a means that the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a face each other and are parallel to each other (i.e., the angle (absolute value) between the opening direction a1 and the opening direction a2 is 3° or less). It is preferable that the opening direction a1 of the first air outlet 21a is a direction facing the opening direction a2 of the second air outlet 22a when viewed from the first direction. Note that the state in which the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a are parallel to each other is also referred to as a parallel state.

[0034] The state in which the opening direction a1 of the first air outlet 21a is inclined or opposed to the opening direction a2 of the second air outlet 22a may be either (I) a state in which at least one of the first air outlet 21a and the second air outlet 22a opens toward the other as viewed from the first direction, or (II) a state in which at least one of the first air outlet 21a and the second air outlet 22a opens toward the other as viewed from the first direction. Either of these is a preferred form of this embodiment.

[0035] As described later, in the hair dryer 1 of this embodiment, at least one of the first blowing section 21 and the second blowing section 22 is connected to the main body section 3 so as to be rotatable about an axis extending in the first direction, so that both the state (I) and the state (II) can be realized, and a user can easily switch between the state (I) and the state (II). The direction in which the first blowing outlet 21a and the second blowing outlet 22a approach each other is referred to as an inward direction, and the direction in which the first blowing outlet 21a and the second blowing outlet 22a move away from each other is referred to as an outward direction.

[0036] When the first blowing section 21 and the second blowing section 22 are positioned so as to realize the above state (I) in the hair dryer 1, the wind blown out from the first blowing outlet 21a and the wind blown out from the second blowing outlet 22a mix together, and the hair can be dried while being pinched by these winds. When the first blowing outlet 21a and the second blowing outlet 22a are positioned so as to pinch the hair, the hair can be dried while being pinched by the first blowing outlet 21a and the second blowing outlet 22a. Therefore, when the user is drying the hair, the hair is less likely to scatter, and the user can easily adjust the position where the wind is blown. Therefore, by using the hair dryer 1, the user can easily set the hair at the same time as drying. Note that, when the user dries the ends of long hair, for example, if the wind is blown to the ends of the hair using a conventional hair dryer, the ends of the hair are blown away by the wind, and it may not be possible to efficiently blow the wind to the ends of the hair. However, the present hair dryer 1 can efficiently deliver air to the ends of the hair, so the drying time can be significantly shortened. The effect of drying the hair while pinching it with multiple airflows or multiple air outlets a as described above is also called the effect of pinching the hair.

[0037] In the state (I), when viewed from the first direction, the acute angle between the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a is less than 90°, preferably 60° or less, more preferably 45° or less, and even more preferably 30° or less. The lower limit of the acute angle is more than 3°, preferably more than 5°. The acute angle refers to the acute angle at the portion where the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a intersect forward in the direction in which the wind is blown out.

[0038] When the first blowing section 21 and the second blowing section 22 are positioned in the hair dryer 1 so as to realize the above state (II), the draping phenomenon is likely to occur depending on the distance between the hair dryer 1 and the hair, and the hair drying time is further shortened. Also, when the first blowing section 21 and the second blowing section 22 are positioned so as to realize the parallel state, when the hair dryer 1 is operated, the draping phenomenon is likely to occur depending on the distance between the hair dryer 1 and the hair, and the hair drying time is further shortened.

[0039] In the state (II), when viewed from the first direction, the acute angle between the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a is less than 90°, preferably 60° or less, more preferably 45° or less, and even more preferably 30° or less. The lower limit of the acute angle is more than 3°, preferably more than 5°. The acute angle refers to the acute angle at the part where the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a intersect at the rear, which is the opposite side to the direction in which the wind is blown out.

[0040] In particular, it is preferable that the first blowing section 21 and the second blowing section 22 can be positioned so 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 inclined with respect to the third direction when viewed from the first direction. The third direction is a normal direction of a plane having as base vectors the first direction and the second direction in which the first blowing section 21 and the second blowing section 22 are separated from each other. The third direction is typically a front-rear direction (up-down direction in FIG. 4). It is more preferable that the first blowing section 21 and the second blowing section 22 can be positioned so that the opening direction a1 of the first blowing outlet 21a faces the second blowing section 22 side and the opening direction a2 of the second blowing outlet 22a faces the first blowing section 21 side when viewed from the first direction. It is also more preferable that the first blowing section 21 and the second blowing section 22 can be positioned so 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.

[0041] As described above, the hair dryer 1 of the present embodiment further includes the main body 3 to which the first blowing section 21 and the second blowing section 22 are attached. At least one of the first blowing section 21 and the second blowing section 22 is connected to the main body 3 so as to be rotatable about an axis extending in the first direction. In such a hair dryer 1, a user can easily switch between, for example, the above state (I) and the above state (II), and therefore the hair dryer 1 is highly convenient.

[0042] At least one of the first blowing section 21 and the second blowing section 22 is rotatable in a direction perpendicular to a first direction (corresponding to the left-right direction in FIG. 4). At least one of the first blowing section 21 and the second blowing section 22 may also be rotatable in another direction (for example, a first direction which is the longitudinal direction of the blowing outlet a).

[0043] Both the first blowing section 21 and the second blowing section 22 may be rotatable, or only one of them may be rotatable. Furthermore, at least one of the first blowing section 21 and the second blowing section 22 may be rotated automatically by electricity, or may be rotated manually by a user. Furthermore, in order to make it easier to rotate at least one of the first blowing section 21 and the second blowing section 22 manually, the blowing section may be made of a flexible member.

[0044] It is preferable that the rotatable blowing part can be locked to rotate at any angle. For example, it is preferable that at least one of the blowing outlets can be locked at an angle at which the first blowing outlet 21a and the second blowing outlet 22a can pinch the hair. The rotation angle is not particularly limited, but for example, the rotatable angle of one blowing part is 0 to 360°.

[0045] When both the first blowing section 21 and the second blowing section 22 are rotatable, they may be rotatable in the same direction or in different directions. The rotation locking position may be, for example, a symmetrical position with respect to a plane extending in the first direction passing through the middle between the first blowing section 21 and the second blowing section 22, or may be a non-symmetrical position. For example, the rotation directions of the first blowing section 21 and the second blowing section 22 may be controlled to be the same rotation direction or to be opposite rotation directions. For example, it is also possible to control the rotation directions of the first blowing section 21 and the second blowing section 22 so that a period in which the rotation direction of the first blowing section 21 and the rotation direction of the second blowing section 22 are the same direction and a period in which the rotation direction of the first blowing section 21 and the second blowing section 22 are opposite directions are alternately positioned. The "rotation direction" means the rotation direction when the blowing section 2 is viewed from the first direction. The rotation direction includes clockwise (right-handed) and counterclockwise (left-handed).

[0046] The hair dryer 1 may include a distance sensor that measures the distance between the hair dryer 1 and the hair to be dried. In this case, the hair dryer 1 may be capable of controlling the angles and rotation directions of the first blowing part 21 and the second blowing part 22 according to the distance to the hair.

[0047] At least one of the first air outlet 21a and the second air outlet 22a may have an air outlet fin 11 near the air outlet (see FIG. 10). The air outlet fin 11 is an air guide member for controlling the flow direction of the air and rectifying the air flow. The air outlet fin 11 may be disposed near each of the first air outlet 21a and the second air outlet 22a, or may be disposed only in one of the first air outlet section 21 and the second air outlet section 22. A plurality of air outlet fins 11 may be disposed at each air outlet a. FIG. 10 is an image diagram of an air outlet a equipped with air outlet fins 11.

[0048] The blowing fins 11 may be fixed to the air outlet, or the angle of the blowing fins may be changed manually by the user, or the angle may be changed automatically by electrical power.

[0049] By controlling the flow of air by the blowing fins 11, the hair dryer 1 can, for example, direct the flow direction (referred to as air direction) of the air blown out from the first blowing outlet 21a and the second blowing outlet 22a inward or outward. Therefore, in the hair dryer 1 of this embodiment, when the blowing outlet has the blowing fins 11, the above state (I) or state (II) is more easily achieved. The blowing fins 11 can also blow the air blown out from the first blowing outlet 21a and the second blowing outlet 22a toward the tip side in the first direction, or toward the base end side in the first direction.

[0050] (Main body 3) In the hair dryer 1 of the present embodiment, a first blowing section 21 and a second blowing section 22 are attached to a main body section 3. In Fig. 1 to Fig. 3 and Fig. 5, the blowing section 2 and the main body section 3 are substantially arranged in a line along a first direction, and the hair dryer 1 has an overall I-shaped outer shape. A power supply cord (not shown) is connected to the main body section 3 or a grip section 4 described below.

[0051] The main body 3 is a part including an intake port for taking in air from the outside, an electric blower for blowing air from the intake port side to the main body outlet side, a heater, and a main body outlet for blowing air to the blowing section 2. In this embodiment, the main body 3 has a plurality of main body outlets, each of which is connected to a plurality of blowing sections 2. Specifically, the first main body outlet 31e is connected to the first blowing section 21, and the air taken in by the main body 3 is blown to the first blowing section 21 via the first main body outlet 31e. In addition, the second main body outlet 32e is connected to the second blowing section 22, and the air taken in by the main body 3 is blown to the second blowing section 22 via the second main body outlet 32e (see FIG. 5).

[0052] The main body 3 preferably has a first main body 31 having a first main body outlet 31e and a second main body 32 having a second main body outlet 32e (see FIG. 1, etc.). The internal space of the first main body 31 serves as a flow path through which air taken in from the outside flows to the first main body outlet 31e, and the internal space of the second outlet section 22 serves as a flow path through which air taken in from the outside flows to the second main body outlet 32e. The first main body 31 and the second main body 32 may be disposed apart from each other, and in this case, the first main body 31 and the second main body 32 may be connected to each other by a support member (see FIG. 1). The first main body 31 and the second main body 32 may be one main body in appearance, and the main body may have a flow path through which air taken in from the outside flows to the first main body outlet 31e and a flow path through which air taken in from the outside flows to the second main body outlet 32e. The first main body 31 and the second main body 32 may be collectively referred to as the main body 3.

[0053] The first main body 31 and the second main body 32 are preferably cylindrical members with an internal space. The cross section may be any of a circular, elliptical, oval, polygonal, etc. An opening (i.e., main body outlets 31e, 32e) for blowing air to the blowing section 2 is formed on the end face of the main body 3 connected to the blowing section 2, and an opening (i.e., air intakes 31b, 32b) for taking in air from the outside is formed on the end face opposite to the face connected to the blowing section 2. The air taken in from the first air intake 31b and the second air intake 32b flows inside the first main body 31 and the second main body 32, respectively, and is blown out from the first main body outlet 31e and the second main body outlet 32e to the blowing section 2, respectively.

[0054] The first body part 31 and the second body part 32 each include an intake port 31b, 32b for taking in air from the outside, an electric blower 31c, 32c for blowing air from the intake port side to the body outlet side, a heater 31d, 32d, and a body outlet 31e, 32e for blowing air to the blowing part 2 (see FIG. 5). The first body part 31 and the second body part 32 each include a control board (not shown). The control board means a board on which a control unit for controlling the operation of the hair dryer 1 is mounted. The control unit has, for example, a chip-like control component and a board on which the control component is mounted. The control unit controls, for example, the electric blower 31c, 32c, the heater 31d, 32d, etc. If the hair dryer 1 has a movable blowing fin 11 or a movable intake fin, the control unit may control these. The hair dryer 1 may have a control board in each of the first main body part 31 and the second main body part 32, or the control board may be provided integrally. Since the control board is disposed between the air intake and the main body air outlet, the control board is cooled by the air flowing inside the main body part 3.

[0055] It is preferable that the first main body portion 31 and the second main body portion 32 are symmetrical with respect to a plane extending in the first direction that passes through the middle between the first main body portion 31 and the second main body portion 32. For example, it is preferable that one or more of the outer shape of each main body portion 3, the positional relationship of each main body portion 3, the position and shape of each portion of each main body portion 3, the flow path area inside each blowing portion 3, the shape and position of each main body blowing port connected to the blowing portion 2, etc. are symmetrical with respect to a plane extending in the first direction that passes through the middle between the first main body portion 31 and the second main body portion 32.

[0056] The position of the first intake port 31b in the first main body portion 31 and the position of the second intake port 32b in the second main body portion 32 may be the same as or different from each other. The positions of the first intake port 31b and the second intake port 32b may be shifted, for example, in the first direction so that the positions of the intake air in the extension direction of the flow path are different.

[0057] The first air intake port 31b and the second air intake port 32b may each have an air intake fin (not shown) in the vicinity thereof. The air intake fin (also called an air guide member) is an air guide member for controlling the air flow direction and straightening the air flow. The air intake fin may be disposed in each of the first air intake port 31b and the second air intake port 32b, or may be disposed in only one of the first air intake port 31b and the second air intake port 32b. A plurality of air intake fins may be disposed in each air intake port.

[0058] The intake fins may be of a type whose angle can be changed (referred to as a movable type). The movable intake fins may be of a type whose angle can be changed automatically by electricity, or may be of a type whose angle can be changed manually by a user. The intake fins may also be of a type whose angle cannot be changed, i.e., may be of a fixed type (referred to as a fixed type).

[0059] A first electric blower 31c is disposed on the upstream side inside the first main body 31, and a first heater 31d is disposed on the downstream side. A second electric blower 32c is disposed on the upstream side inside the second main body 32, and a first heater 31d is disposed on the downstream side. The upstream side and the downstream side refer to the upstream side and the downstream side in the air flow direction, respectively. The intake port side is the upstream side, and the main body outlet side is the downstream side.

[0060] The position of the first electric blower 31c in the first main body portion 31 and the position of the second electric blower 32c in the second main body portion 32 may be the same as or different from each other. When they are arranged at the same position, the hair dryer 1 can easily blow air at the same temperature and at the same wind speed from the first air outlet 21a and the second air outlet 22a.

[0061] An electric blower is a general term for a mechanism that blows air using electricity. For example, an electric blower may be a mechanism that blows air by rotating a member that forms an airflow, such as a fan, using electricity, or may be a mechanism that generates an airflow by forming high and low pressure areas by generating vibrations or the like using electricity. For example, an electric blower preferably includes a fan and a motor that drives the fan. The positional relationship between the fan and the motor in the flow direction is not particularly limited. For example, the fan may be positioned upstream and the motor may be positioned downstream.

[0062] 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 further preferably a brushless DC motor.

[0063] Since the brushless motor does not have a brush that contacts the rotor, it can suppress the generation of noise due to the contact between the brush and the rotor. Therefore, it can achieve further quieting. The brushless motor includes, for example, a motor in which a permanent magnet for a field is arranged on the rotor side and an armature winding is arranged on the stator side, and a motor in which the current is controlled by feedback to an inverter using a sensor (e.g., a Hall sensor) for detecting a rotor signal instead of switching the current using a brush by changing the position of a commutator. The brushless motor may be, for example, a motor that generates a rotating magnetic field by changing the direction of the current using a switch such as a semiconductor switch to rotate the rotor. Note that the induction motor may be a motor that generates a sine wave that is out of phase with the power source to rotate the magnetic field. The synchronous reluctance motor is a type of synchronous motor, and may be, for example, a motor that rotates as an induction motor at start-up and rotates in synchronization with the power source frequency during operation.

[0064] The air flowing through the flow path inside the first main body portion 31 can be heated by the first heater 31d. The air flowing through the flow path inside the second main body portion 32 can be heated by the second heater 32d. When the heaters 31d, 32d are in an energized state (referred to as an on state), hot air is blown out from the first air outlet 21a and the second air outlet portion 22. By putting the heaters 31d, 32d in a non-energized state (referred to as an off state), it is possible to blow out cool air that is not heated by the heaters 31d, 32d from the first air outlet 21a and the second air outlet portion 22. "Heated" means that the temperature of the gas discharged from the region where the heaters are provided is higher than the temperature of the gas (e.g., air) before it is guided to the region where the heaters are provided.

[0065] As described above, the main body 3 includes a plurality of electric blowers (electric blowers 31c, 32c). By providing a plurality of electric blowers, the volume of noise generated when blowing out a certain amount of air can be made smaller than when blowing out from a single electric blower. This makes it possible to reduce noise throughout the hair dryer. In this way, the hair dryer 1 of this embodiment can achieve a large amount of air while still being quiet.

[0066] A heater and an electric blower are provided in each of the multiple flow paths provided in the main body 3. For this reason, 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, it is possible to blow air of different temperatures and volumes from each of the multiple flow paths. Therefore, for example, even when the hair dryer is maintained in a fixed position and fixed attitude, it is possible to alternately blow low-temperature air and high-temperature air to multiple adjacent areas, or to alternately blow high-volume air and low-temperature air to multiple adjacent areas. In addition, it is possible to alternately blow high-temperature and high-volume air and low-temperature and low-volume air to multiple adjacent areas, or to alternately blow high-temperature and low-volume air and low-temperature and high-volume air. Therefore, for example, it is possible to improve quick-drying while preventing damage to hair.

[0067] In addition, the electric blowers arranged in two adjacent flow paths among the multiple flow paths may be rotatable 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 or opposite to each other. For example, it is possible to control the rotation directions of the first electric blower 31c and the second electric blower 32c so that a period in which the rotation directions of the first electric blower 31c and the second electric blower 32c are the same and a period in which the rotation directions are opposite to each other are alternately positioned. The "rotation direction" means the rotation direction when viewed along the flow path direction of the flow path in which the electric blower is provided. The rotation direction includes clockwise (right-handed) and counterclockwise (left-handed).

[0068] For example, by reversing the rotation direction of the first electric blower 31c and 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 be in opposite phase. Therefore, the sounds and vibrations generated by the electric blowers can be cancelled out by each other, so that further quieting can be achieved and the vibration of the hair dryer 1 can be reduced. In particular, it is preferable that the shapes of the fans included in the electric blowers arranged in each of the two adjacent flow paths are symmetrical. These two electric blowers may be rotatable in the same rotation direction or in different rotation directions.

[0069] In the above, a configuration in which an electric blower and a heater are provided for each of the multiple flow paths provided in the main body 3 has been described, but the present invention is not limited to this configuration. For example, it is preferable that an electric blower is provided for at least two of the multiple flow paths. When three or more flow paths are provided, at least one flow path does not need to have an electric blower. It is preferable that an electric blower is provided for two adjacent flow paths among the multiple flow paths. It is not necessary for a heater to be provided for each of the multiple flow paths. It is preferable that a heater is provided for at least two flow paths provided with an electric blower among the multiple flow paths. However, it is not necessary for a heater to be provided for a part of the at least two flow paths provided with an electric blower.

[0070] (Gripping part 4) The hair dryer 1 of the present embodiment may further include a grip part 4 (see FIG. 1). The grip part 4 is a part that is held by a user when using the hair dryer 1. Note that the hair dryer 1 may not include the grip part 4, and may be, for example, a stationary hair dryer.

[0071] From the viewpoint of reducing the burden on the user, it is preferable that the grip part 4 is attached at a position close to the center of gravity of the hair dryer 1. In Figs. 1 to 3 and 5, the blowing part 2, the main body part 3 and the grip part 4 are substantially arranged in a line along the first direction. The hair dryer 1 has an overall I-shaped outer shape. The grip part 4 may be arranged in a direction inclined with respect to the first direction (for example, a direction perpendicular to the first direction).

[0072] The grip portion 4 is provided with operation units (e.g., 41, 42). When using the hair dryer 1, the user operates the operation unit (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, air direction, etc. of the air from the air outlet a by operating the operation unit (e.g., the operation button 41, etc.).

[0073] 1 has a plurality of operation buttons 41 and one power switch 42 as an operation unit, but the hair dryer 1 of this embodiment is not limited to such a configuration. For example, the operation unit may include a lever, a cyclic stick, or the like. When the operation unit includes a lever, a cyclic stick, or the like, by matching the sliding direction of the lever or cyclic stick with the rotation direction of the blow-out unit 2, the user can easily recognize the rotation direction of the blow-out unit 2 visually or by feeling.

[0074] The hair dryer 1 of this embodiment can efficiently dry hair by generating a drape phenomenon (i.e., can efficiently supply air to hair). The hair dryer 1 of this embodiment can also enable the user to easily set the hair while drying it, and can have styling properties that make it easy to achieve the intended styling. Furthermore, the hair dryer 1 of this embodiment can perform everything from drying hair after washing to setting the base. Therefore, the hair dryer 1 of this embodiment can achieve beautiful hair quick drying. It is particularly preferable that the hair that the hair dryer 1 of this embodiment targets is long hair. In other words, it is particularly preferable that the hair dryer 1 of this embodiment is a hair dryer for long hair. The hair dryer 1 of this embodiment can also achieve a large amount of air with low noise and low vibration.

[0075] (Embodiment 2) In this embodiment, the features unique to this embodiment will be mainly described, and the description of the contents overlapping with the above embodiment will be omitted. The hair dryer 1 of this embodiment is substantially different from the first embodiment in that the blowing unit 2 is an attachment 5 that is detachable from the main body 3.

[0076] The hair dryer 1 of the present embodiment includes a main body section 3 including a first main body outlet 31e and a second main body outlet 32e, and an attachment 5 detachable from the main body section 3, and the attachment 5 includes a first outlet section 21 connectable to the first main body outlet 31e and a second outlet section 22 connectable to the second main body outlet 32e. Similar to the hair dryer 1 of the first embodiment, the first outlet section 21 includes a first outlet 21a formed in an elongated shape along the first direction, and the second outlet section 22 includes a second outlet 22a formed in an elongated shape along the first direction.

[0077] The attachment 5 may be composed of one attachment having a first blowing section 21 and a second blowing section 22, or may be composed of multiple attachments including a first attachment having a first blowing section 21 and a second attachment having a second blowing section (see FIG. 11B described below).

[0078] The first blowing section 21 and the second blowing section 22 are positioned such that, when the attachment 5 is attached to the main body section 3, the first blowing section 21 and the second blowing section 22 are arranged at a distance from each other and the opening direction a1 of the first blowing outlet 21a is inclined or opposed to the opening direction a2 of the second blowing outlet 22a.

[0079] The hair dryer 1 of the present embodiment may be, for example, a hair dryer 1 that can realize the above state (I) or state (II) when the user attaches the attachment 5, and can realize the parallel state when the user detaches the attachment 5 (see Figs. 11A and 11B). In such a hair dryer 1, the user can switch between the parallel state and the above state (I) or state (II) simply by attaching and detaching the attachment 5. Furthermore, when an attachment 5 consisting of multiple attachments is used, the user can also switch between the above state (I) and state (II) simply by attaching one or more of the multiple attachments in the opposite direction. Therefore, the hair dryer 1 of the present embodiment is highly convenient.

[0080] An example of how the attachment 5 is attached and detached will be described with reference to Figures 11A and 11B. Figure 11A is an image diagram of the attachment 5 before it is attached. Figure 11B is an image diagram of the attachment 5, which is made up of two attachments, after it has been attached.

[0081] In Fig. 11A, the opening direction a1 of the first air outlet 21a and the opening direction a2 of the second air outlet 22a are parallel to each other (parallel state). On the other hand, as shown in Fig. 11B, when two attachments 5 are attached to the first body part 31 and the second body part 32 via the first body air outlet 31e and the second body air outlet 32e, respectively, the opening direction a1 of the first air outlet 21a of the first attachment 5 becomes a direction inclined with respect to the opening direction a2 of the second air outlet 22a of the second attachment 5. The state shown in Fig. 11B corresponds to the above state (I), but for example, when at least one of the attachments 5 shown in Fig. 11B is attached in a direction such that it opens toward a direction away from the other attachment 5, the above state (II) can be realized.

[0082] The hair dryer 1 of this embodiment, like the hair dryer 1 of the first embodiment, can efficiently supply air to hair, and can also allow the user to easily set the hair while drying it, and can have styling properties that make it easy to achieve the intended styling. The hair dryer 1 of this embodiment can also perform everything from drying hair after washing to setting the base, and can achieve beautiful and quick-drying of hair. It is particularly preferable that the hair dryer 1 of this embodiment is also a hair dryer for long hair. Furthermore, the hair dryer 1 of this embodiment can achieve various air flows just by changing the attachment, so that it can easily meet the detailed requests of the user at low cost.

[0083] (Modification of the second embodiment) In the second embodiment, a hair dryer 1 has been described that includes a main body 3 and an attachment 5 detachably attached to the main body 3, and the attachment 5 has a first blowing section 21 connectable to the first main body blowing outlet 31e and a second blowing section 22 connectable to the second main body blowing outlet 32e, but the hair dryer 1 may have an attachment 5 detachably arranged as an outlet in at least one of the first blowing section 21 and the second blowing section 22. In the present modified example, a hair dryer 1 will be described that includes a main body 3, a first blowing section 21 and the second blowing section 22, and has one or more attachments 5 (referred to as blowing outlet attachments 5) detachably arranged in at least one of the first blowing section 21 and the second blowing section 22.

[0084] The air outlet attachment 5 may be detachably arranged on each of the first air outlet section 21 and the second air outlet section 22, or may be detachably arranged on only one of the first air outlet section 21 and the second air outlet section 22. Of the openings of the air outlet attachment 5, the opening on the side from which the wind is blown out preferably has a shape similar to the first air outlet 21a of the first air outlet section 21 or the second air outlet 22a of the second air outlet section 22. Therefore, the opening on the side from which the wind is blown out of the air outlet attachment 5 preferably has a shape elongated in the first direction.

[0085] An example of the hair dryer 1 of this modified example corresponds to a structure in which, for example, in FIG. 11B, the first main body portion 31, the first main body outlet 31e, the second main body portion 32, and the second main body outlet 32e are read as the first outlet portion 21, the first outlet 21e, the second outlet portion 22, and the second outlet 22a, respectively.

[0086] (Embodiment 3) In this embodiment, the features unique to this embodiment will be mainly described, and the description of the contents overlapping with the above embodiment will be omitted. The hair dryer 1 of this embodiment is substantially different from the first embodiment in that the blowing unit 2 is fixed to the main body 3.

[0087] The hair dryer 1 of the present embodiment includes a first blowing section 21 having a first blowing outlet 21a formed in an elongated shape along a first direction, and a second blowing section 22 having a second blowing outlet 22a formed in an elongated shape along the first direction, and the first blowing section 21 and the second blowing section 22 are arranged apart from each other, and the first blowing section 21 and the second blowing section 22 are positioned such that the opening direction a1 of the first blowing outlet 21a is inclined or opposed to the opening direction a2 of the second blowing outlet 22a. In the present embodiment, the first blowing section 21 and the second blowing section 22 are arranged so that the above state (I) or the above state (II) is realized.

[0088] (Embodiment 4) In this embodiment, the features unique to this embodiment will be mainly described, and the description of the contents overlapping with the above-mentioned embodiment will be omitted. The hair dryer 1 of this embodiment is substantially similar to the hair dryer 1 of the first, second or third embodiment, except that the wind speed of the wind blown out from at least one end of the air outlet is higher than the wind speed of the wind blown out from the center part C of the air outlet.

[0089] In the hair dryer 1 of the present embodiment, at least one of the first air outlet 21a and the second air outlet 22a is configured so that the wind speed of the air blown out from at least one of the ends E1, E2 in the first direction of the air outlet is higher than the wind speed of the air blown out from the center C in the first direction. In particular, it is preferable that the wind speed of the air blown out from at least one of the ends E1, E2 in the first direction of the first air outlet 21a is higher than the wind speed of the air blown out from the center C in the first direction, and the wind speed of the air blown out from at least one of the ends E1, E2 in the first direction of the second air outlet 22a is higher than the wind speed of the air blown out from the center C in the first direction. The hair dryer 1 of the present embodiment can further exert the above-mentioned effects of hair pinching and draping phenomenon.

[0090] Moreover, it is preferable that at least one of the first air outlet 21a and the second air outlet 22a is configured so that the wind speed of the wind blown out from each of the two end portions E1 and E2 in the first direction of the air outlet is greater than the wind speed of the wind blown out from the center portion C in the first direction. In particular, it is more preferable that the wind speed of the wind blown out from each of the two end portions E1 and E2 in the first direction of the first air outlet 21a is greater than the wind speed of the wind blown out from the center portion C in the first direction, and that the wind speed of the wind blown out from each of the two end portions E1 and E2 in the first direction of the second air outlet 22a is greater than the wind speed of the wind blown out from the center portion C in the first direction. When the speed of the air blown out from both ends E1 and E2 in the first direction of the air outlet is greater than the speed of the air blown out from the center C in the first direction, a curtain of air is generated in the vicinity of the tip ends E1 of the first air outlet 21a and the second air outlet 22a and in the vicinity of the base ends E2 of the first air outlet 21a and the second air outlet 22a. Therefore, for example, when the first air outlet section 21 and the second air outlet section 22 are positioned so as to realize the above-mentioned state (I) in the hair dryer 1, the hair dryer 1 can blow out all the air inward toward the part sandwiched between the two curtains, thereby further enhancing the effect of the hair being pinched as described above.

[0091] The hair dryer 1 of this embodiment can be realized, for example, by applying to the hair dryer 1 of embodiment 1, 2 or 3 one or more of the following techniques: (i) adjusting the opening ratio by modifying the shape of the air outlet a; (ii) arranging air outlet fins near the air outlet a and adjusting the number, position and orientation of the air outlet fins; (iii) modifying the operation control of the electric blower.

[0092] For example, in one embodiment of the hair dryer 1 in which the above technique (i) is adopted, the opening width of at least one of the ends in the first direction of at least one of the first air outlet 21a and the second air outlet 22a (i.e., the opening width L E1 and the opening width L of the base end E2 E2 At least one of the above) is the opening width L of the central portion C in the first direction. CIt is a larger form than (L E1 >L C , or L E2 >L C This allows the wind speed blown out from the end portion to be greater than the wind speed blown out from the center portion C. E1 and the opening width L of the base end E2 E2 Both of the opening width L of the central part C C It is greater than (L E1 >L C , and L E2 >L C ) is more preferred.

[0093] (Embodiment 5) In this embodiment, the features unique to this embodiment will be mainly described, and the description of the contents overlapping with the above-mentioned embodiment will be omitted. The hair dryer 1 of this embodiment is substantially similar to the hair dryer 1 of the first, second, third or fourth embodiment, except that the wind speed of the wind blown out from at least one tip end E1 of the air outlet is higher than the wind speed of the wind blown out from the base end E2 of the air outlet.

[0094] In the hair dryer 1 of the present embodiment, at least one of the first air outlet 21a and the second air outlet 22a is configured so that the wind speed of the air blown out from the tip end E1 in the first direction of the air outlet is greater than the wind speed of the air blown out from the base end E2 in the first direction of the air outlet.
