[0008] [Embodiment] The following describes embodiments with reference to the drawings. Various features shown in the following embodiments can be combined with each other.

[0009] FIG. 1 is a perspective view of a dryer 100 according to the present invention. The shape of the dryer 100 according to this embodiment has an appearance similar to that of a typical handheld dryer. Users can use the familiar shape to dry their hair, and it can be stored in a conventional location. Note that the shape of the dryer is not limited to this embodiment, and can be changed as desired within the scope of the claims.

[0010] The dryer 100 is configured to include a main body 101 and a handle 102. The main body 101 is the part that corresponds to the main body and houses the main functions (such as the air blowing function) of the dryer 100. The main body 101 blows air in an air blowing direction D1 from the rear to the front. The handle 102 extends downward from the underside of the main body 101. The handle 102 is configured to include a switch 103 that operates the functions of the dryer 100 and a hand electrode 104 that is used to recover electric charge, as described below. The dryer 100 is powered by a power cord connected to the lower end of the handle 102. It is to be noted that the dryer 100 may be equipped with an internal battery to make it a cordless dryer.

[0011] Attachment 1 is a brush-type attachment that is attached to dryer 100, and is detachably attached to the tip (end on the airflow direction D1 side) of main body 101. Hereinafter, the airflow direction D1 side of attachment 1 will be referred to as the front, and the opposite side (the side connected to main body 101) will be referred to as the rear. Attachment 1 will be described below with reference to Figure 2 in addition to Figure 1.

[0012] Fig. 2 is a diagram showing the attachment 1 as seen from the side. Fig. 3 is a diagram showing the attachment 1 as seen from diagonally forward. Fig. 4 is a diagram showing the attachment 1 as seen from diagonally rearward. Fig. 5 is a diagram showing the attachment 1 as seen from the front. Fig. 6 is a diagram showing the attachment 1 as seen from the rearward.

[0013] The attachment 1 includes a fixed part 2 and a rotating part 3. The fixed part 2 includes an intake port 21 at the rear thereof that receives air sent from the dryer 100, and is configured to be fixed in position relative to the dryer 100. Air sent out from the main body 101 of the dryer 100 passes through the intake port 21 and is drawn into the internal space S1 of the attachment 1.

[0014] The rotating part 3 has a plurality of bristles 32 and a plurality of air outlets 33, and is configured to be rotatably supported by the fixed part 2. In detail, the rotating part 3 has a hollow cylindrical body 31, and a plurality of bristles 32 are provided on the outer peripheral surface 311 of the cylindrical body 31. A plurality of air outlets 33 are provided in the cylindrical body 31. The air sucked through the intake port 21 of the fixed part 2 passes through the internal space S1 of the attachment 1, is blown out from the plurality of air outlets 33, and reaches the user's hair that comes into contact with the plurality of bristles 32.

[0015] According to this embodiment, the dryer 100 can be used while rotating the brush with the bristles 32, so that the hair can be heated and set at the same time. This makes it possible to set curls with a simpler operation than when the bristles 32 do not rotate, thereby improving usability.

[0016] The attachment 1 is configured so that the relationship (total area of ​​the air outlets 33) is less than or equal to the total area of ​​the air inlets 21. The air inlets 21 and the air outlets 33 each form a space through which air passes, and the "total area" here refers to the sum of the cross-sectional areas of these spaces (the areas of the cross sections perpendicular to the direction of air passage). It is known that as the flow path narrows and the flow rate increases, the pressure decreases (according to Bernoulli's equation). Therefore, this embodiment allows the pressure at the air outlets 33 to be reduced and the pressure at the air inlets 21 to be increased. As a result, even if there are multiple air outlets 33, there is no backflow of air from the air outlets 33 to the air inlets 21, and the pressure at the air outlets 33 can be kept constant everywhere. This reduces uneven hair treatment compared to when the relationship between the total areas is reversed.

[0017] Fig. 7 is a partial cross-sectional view of the attachment 1 seen from diagonally front. Fig. 8 is a partial cross-sectional view of the attachment 1 seen from diagonally rear. Fig. 9 is a cross-sectional view of the attachment 1 seen from diagonally rear. The fixed part 2 has partition parts 22-1 and 22-2 (when there is no need to distinguish between them, they will be referred to as "partition part 22"). The partition part 22 is a plate-shaped part that divides the internal space S1 of the attachment 1.

[0018] Partitions 22-1 and 22-2 intersect at right angles to divide internal space S1 into four divided spaces S11-1, S11-2, S11-3, and S11-4 (referred to as "divided spaces S11" when not distinguishing between them). Each divided space S11 is provided with flow velocity reduction sections 23-1, 23-2, and 23-3 (referred to as "flow velocity reduction section 23" when not distinguishing between them) in order from the side closest to intake port 21.

[0019] Flow velocity reduction sections 23-1 and 23-2 are plate-shaped sections with surfaces facing inlet 21, and the blown air collides with these surfaces to reduce the flow velocity of the air flowing through partition space S11. Because flow velocity reduction section 23-2 is larger than flow velocity reduction section 23-1, flow velocity reduction section 23-2 reduces the flow velocity more than flow velocity reduction section 23-1. Furthermore, flow velocity reduction section 23-3 forms a retention space in front of partition space S11 where the blown air stagnates, i.e., where the flow velocity in air blowing direction D1 is zero, and is positioned so that air leaking from this retention space is blown out from air outlet 33, which is the frontmost.

[0020] Thus, fixed component 2 has flow velocity reduction mechanisms (flow velocity reduction sections 23-1, 23-2, 23-3) arranged opposite suction port 21. These flow velocity reduction sections 23 are configured to reduce the flow velocity more significantly as they are farther away from suction port 21.

[0021] According to this embodiment, of the kinetic energy term, pressure energy term, and potential energy term in Bernoulli's equation, the kinetic energy term related to velocity can be reduced by the flow velocity reduction means and converted into pressure. In other words, the pressure is lower at the outlet 33 closer to the inlet 21 because the flow velocity is faster, and the pressure is higher at the outlet 33 farther from the inlet 21 because the flow velocity is slower. The amount of ions contained in a unit volume of air is greatest when the air is inhaled through the inlet 21 and decreases each time ions are blown out from the outlet 33. Therefore, by increasing the pressure at the outlets 33 farther from the inlet 21 to increase the amount of air flowing out, the amount of ions contained in the air blown out from the outlet 33 can be made closer to a constant amount compared to when the pressure at the outlet 33 is constant everywhere, and as a result, static electricity can be more evenly removed from one or both of the hair and the bristles 32.

[0022] Next, the sliding portion 4 provided between the fixed component 2 and the rotating component 3 will be described. The sliding portion 4 is a portion provided to allow the rotating component 3 to slide, in other words, to rotate while sliding. As shown in FIG. 9, the fixed component 2 has groove portions 24-1 and 24-2 (when there is no need to distinguish between them, they will be referred to as "groove portion 24") on the outer circumferential surface facing the rotating component 3. Groove portion 24-1 is provided at the rear end of the fixed component 2, and groove portion 24-2 is provided at the front end of the fixed component 2.

[0023] An O-ring 41-1 is fitted in groove 24-1, and an O-ring 41-2 (referred to as "O-ring 41" when not distinguishing between them) is fitted in groove 24-1. O-ring 41 is an elastic, annular part. O-ring 41-1 faces the inner circumferential surface of annular part 34-1 of rotating part 3. O-ring 41-2 faces the inner circumferential surface of annular part 34-2 of rotating part 3 (referred to as "annular part 34" when not distinguishing between them).

[0024] FIG. 10 is an enlarged view of the O-ring 41. FIG. 10 shows the O-ring 41-2 provided in front of the fixed component 2. A gap M1-2 is provided between the O-ring 41-2 and the annular component 34-2. A gap M1-1 (referred to as "gap M1" when not distinguishing between them) is also provided between the O-ring 41-1 provided behind the fixed component 2 and the annular component 34-1. Due to the provision of the gap M1, the annular component 34 and the O-ring 41 do not come into contact with each other during rotation of the rotating component 3, or even if they do come into contact, the contact area is extremely small. As a result, the rotating component 3 rotates while sliding on the surface of the O-ring 41. In this way, the O-ring 41 is the sliding part 4 of the attachment 1.

[0025] As shown in Fig. 9, the sliding parts 4 (O-rings 41) are located at both ends of the fixed part 2 in the longitudinal direction (air blowing direction D1). The fixed part 2 rotatably supports the rotating part 3 via the sliding parts 4, but if a force is applied to the rotating part 3 in a direction other than the rotational direction, the fixed part 2 supports that force, preventing the rotating part 3 from wobbling. If the sliding part 4 were provided only at one end of the fixed part 2 in the longitudinal direction, the other end would be more likely to wobble. However, by providing the sliding parts 4 at both ends as described above, the rotating part 3 is held stably and can be rotated with less wobbling.

[0026] The sliding part 4 is an O-ring 41 fitted to the fixed part 2. The rotating part 3 has an annular part 34 having a surface facing the O-ring 41. The rotating part 3 is configured so that a gap M1 is formed between the O-ring 41 and the annular part 34. According to this embodiment, since there is the gap M1 between the O-ring 41 and the annular part 34, the bristles 32 can be rotated with less force than when there is no gap M1, making it easier to style hair and improving usability. Furthermore, even if the gap M1 becomes smaller due to expansion or deformation of the parts caused by heat, the elasticity of the O-ring 41 can absorb changes in rotational force, thereby reducing fluctuations in operating force and improving usability compared to when the O-ring 41 is not provided.

[0027] In the example of FIG. 9, an O-ring 41 is provided at each of the front and rear ends of the fixed component 2. However, this is not limiting. Alternatively, an O-ring 41-2 may be provided only at the front end, and no O-ring 41 may be provided at the sliding portion at the rear end. In this case, the sliding portion is configured to form a gap M1-1 between the fixed component 2 and the annular component 34-1 provided at the rear end of the rotating component 3. According to this embodiment, the O-ring 41-2 contacts the annular component 34-2 at the sliding portion farther from the dryer 100 (the portion where the gap M1-2 is formed). This reduces noise due to rotation and vibration and reduces wobbling compared to a case where the O-ring 41-2 is not provided. Furthermore, a simple structure can be achieved without an O-ring at the sliding portion closer to the dryer 100 (the portion where the gap M1-1 is formed).

[0028] The main body 101 of the dryer 100 has an ionizer, which is an ion supply unit, inside, and supplies positive ions or negative ions together with the airflow. The release of electric charge by the ionizer and the collection of electric charge by the hand electrode 104 will be described with reference to FIG.

[0029] Fig. 11 is a block diagram showing an example of the configuration of the function for discharging and collecting electric charges. As shown in the figure, ionizer 5, which is the electric charge discharging means, is equipped with positive ion generating section 51 that generates positive ions and negative ion generating section 52 that generates negative ions, and is configured to be able to generate positive ions and negative ions simultaneously or alternately. The electric charge collecting means includes a hand electrode 104 that comes into contact with the user. A potential control section 55 that controls the electric potential of hand electrode 104 is connected to hand electrode 104.

[0030] The potential control unit 55 can control the potential of the hand electrode 104, and can apply a ground potential to the hand electrode 104, for example. This allows the hand electrode 104 to collect negative charges when many negative ions accumulate in the hair, and collect positive charges when many positive ions accumulate, thereby quickly eliminating static electricity from the hair and also providing secondary benefits of the negative ions, such as increased moisture and improved skin quality. It is desirable that the potential control unit 55 be configured to be insulated from the commercial power supply.

[0031] The ionizer 5 also includes a charge state detection unit 53 and a charge release control unit 54. The charge state detection unit 53 is configured to be able to detect the charge state of the user. The charge release control unit 54 controls the amount of at least one of the positive ions and negative ions released by the ionizer 5 so that the charge state of the user becomes a predetermined state. Note that the ionizer 5 may include only either the positive ion generation unit 51 or the negative ion generation unit 52.

[0032] In this way, when the attachment 1 is connected to the dryer 100, it is configured to transmit positive ions and / or negative ions emitted from the ionizer 5 and sent out from the dryer 100 to the user's hair that comes into contact with the bristles 32. Meanwhile, the bristles 32 are formed of charged bodies. One example of the charged body is a conductive resin in which a conductive carbon material is composited with a resin. Examples of resins that can be used include ABS resin, PP resin (polypropylene resin), and PA / ABS resin.

[0033] Fig. 12 is a diagram showing how easily substances are charged. As shown in Fig. 12, hair tends to be positively charged, while resins such as PP (polypropylene) resin that form the bristles 32 tend to be negatively charged. The attachment 1 transfers negative ions to the user's hair that comes into contact with the bristles 32, thereby removing positive ions carried by the hair, and transfers positive ions to the bristles 32, thereby removing negative ions carried by the bristles 32.

[0034] When hair and bristles 32 are electrically charged, the hair is susceptible to damage due to friction between the hair and bristles 32, but the above-described embodiment can reduce at least one of the positive ions in the hair and the negative ions in the bristles. As a result of removing static electricity using ions in this way, even when the brush is applied hard to the hair, hair sticking is reduced and damage to the hair due to friction can be reduced compared to when ions are not supplied.

[0035] The dryer 100 also includes the attachment 1. According to this embodiment, the attachment 1 is replaceable, making it possible to provide a dryer that is suitable for a variety of hair lengths or hair types.

[0036] The dryer 100 further includes a throttle portion provided in the air flow path. 13 is a diagram showing the throttling portion 105. The throttling portion 105 is provided in the flow path inside the main body 101, and reduces the cross-sectional area of ​​the flow path compared to when the throttling portion 105 is not present. However, the throttling portion 105 is configured so that (total area of ​​the outlets 33 of the attachment 1)≦(total area of ​​the throttling portions 105). According to this embodiment, even when a large cross-sectional area cannot be secured due to the blades of the dryer or the vanes of the motor, the pressure at the outlets 33 of the attachment 1 can be reduced, preventing backflow of air and allowing air to be blown out efficiently.

[0037] The attachment 1 may be provided with a mechanism for locking the rotation of the rotating part 3. Figure 14 is a diagram showing an example of a locking mechanism. The attachment 1a shown in Figure 14 includes a fixed part 2a, a rotating part 3a, and a locking mechanism 7. The locking mechanism 7 is a mechanism that switches between a rotating state in which the rotating part 3a rotates and a locked state in which the rotating part 3a does not rotate when a predetermined operation is performed. The locking mechanism 7 includes a first locking part 71 and a second locking part 73. The first locking part 71 includes a locking rod 72. The second locking part 73 has a locking hole 74.

[0038] The rotating component 3a has a knock portion 35 at its tip. The knock portion 35 is provided so as to be able to move back and forth in the airflow direction D1 and a pushing direction D2 opposite to the airflow direction D1. The first locking component 71 is biased in the airflow direction D1 by a biasing member such as a spring (not shown), and is provided so that its end on the airflow direction D1 side comes into contact with the knock portion 35. Therefore, when the knock portion 35 is pushed in the pushing direction D2 by a user's operation, the force received from the knock portion 35 also moves the first locking component 71 in the pushing direction D2.

[0039] The second locking component 73 is a disk-shaped member and is fixed to the tip 25 of the fixed component 2a. The locking rod 72 has locking holes 74 formed in two locations. On the other hand, the first locking component 71 has two locking rods 72 that are large enough to be inserted into the locking holes 74. When the first locking component 71 moves in the pushing direction D2, the two locking rods 72 are inserted into the two locking holes 74, respectively. Once the locking rods 72 are inserted into the locking holes 74, even if an attempt is made to rotate the rotating component 3a, the locking rods 72 become caught in the locking holes 74, preventing the rotating component 3a from rotating.

[0040] Once the first locking component 71 is pushed in by the knock portion 35, a temporary fixing mechanism (not shown) temporarily fixes the locking rod 72 at a position where it is inserted into the locking hole 74. When the first locking component 71 is temporarily fixed in this manner, the rotating component 3a does not rotate, i.e., it is in a locked state. FIG. 15 is a diagram showing an example of a locked state. In FIG. 15, the first locking component 71 remains pushed in, and the knock portion 35 has returned to its original position. When the knock portion 35 is pushed in again, the first locking component 71 is released from its temporarily fixed state and returns to the position shown in FIG. 14. When the first locking component 71 returns to its original position, the rotating component 3a enters a rotating state in which it rotates. In this way, the operation of pushing the knock portion 35 is an operation of switching between the rotating state and the locked state, and is an example of a predetermined operation.

[0041] The temporary fixing mechanism may be, for example, a knock cam mechanism used in ballpoint pens. The knock cam mechanism includes a knock portion, a rotatable cam, and a spring that biases the cam. The cam has multiple grooves positioned at different positions in the pushing direction D2, and each time the cam rotates, a different groove engages with a protrusion on the rotating part 3a. When the knock portion is knocked, the knock portion pushes and rotates the cam, and the grooves of the rotated cam engage with the protrusion, switching between a state in which the first locking component 71 is temporarily fixed in the pushed-in position and a state in which the first locking component 71 is temporarily fixed in a position where it has returned to the airflow direction D1. Note that other well-known techniques may also be used as the temporary fixing mechanism, such as a snap-fit ​​mechanism (a fixing method that uses the elasticity of a material to hook a protrusion) or a plunger lock mechanism (a fixing method that hooks a protrusion by rotating a knob).

[0042] According to the above-described embodiment, the rotary element 3a can be rotated to curl the hair, or locked to straighten the hair. Furthermore, even if the user desires a complicated hair treatment in which the hair is straightened partway and then curled at the ends, the treatment can be performed more easily than if the locking mechanism is not provided, since there is no need to change the attachment.

[0043] The rotating element 3 and the bristles 32 may be configured to stimulate the hair or scalp with electricity, vibration, liquid or gas spray, light, or electromagnetic waves. Therefore, the attachment 1 may be configured to have an internal substrate, light source, or vibration mechanism for providing these stimuli. According to this embodiment, various stimuli can be applied to the hair or scalp while drying the hair.

[0044] The attachment 1 and the main body 101 of the dryer 100 may have information transmission means. For example, when the attachment 1 is attached to the main body 101, information indicating that the attachment 1 has been attached is transmitted to the main body 101. In this case, the dryer 100 may be configured to change its operating state depending on whether the attachment 1 is attached or not. Examples of the changeable operating state include the air volume, the air temperature, and the amount of ions emitted. For example, if a switch is used to switch between an operating state suitable for when the attachment 1 is not attached and an operating state suitable for when the attachment 1 is attached, it is time-consuming to switch the switch, and the user may forget to switch the switch. Therefore, for example, by automatically switching the operating state when the attachment 1 is attached or detached, the user can continue to use the dryer 100 in an operating state suitable for the current situation without the hassle of switching.

[0045] The attachment 1 is not limited to being made of resin or silicone rubber, but may be configured to include ceramic containing metal or glass in part. This configuration allows for greater freedom in designing the strength and texture of the attachment 1 than when it is made of a single material.

[0046] The total cross-sectional area of ​​the air outlet 33 is 100 mm 2 More than 1000mm 2The range can be: 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, 510, 520, 530, 540 ,550,560,570,580,590,600,610,620,630,640,650,660,670,680,690,700,710,720,730,740,750,760,770, 780,790,800,810,820,830,840,850,860,870,880,890,900,910,920,930,940,950,960,970,980,990,1000mm 2 It may be in the range between any two of the above.

[0047] Furthermore, the outer surface 311 of the cylinder 31 on which the air outlet 33 is provided has a flat shape in the air blowing direction D1, but it may have a shape with a bulging center like a barrel, or conversely, a shape with a recessed center.

[0048] [others] Furthermore, it may be provided in the following aspects.

[0049] (1) A brush-type attachment to be attached to a dryer, comprising a fixed part and a rotating part, the fixed part having an intake port for receiving air from the dryer and configured to be fixed in position relative to the dryer, and the rotating part having bristles on its side and an outlet port for blowing out the air, configured to be rotatably supported by the fixed part.

[0050] According to this aspect, the dryer can be used while rotating the bristled brush, so that the hair can be heated and set at the same time, making curling possible with simpler operations and improving usability.

[0051] (2) In the attachment described in (1) above, a sliding part is provided between the fixed part and the rotating part, and the sliding part is located at both ends of the fixed part in the longitudinal direction.

[0052] According to this aspect, the rotating member can be stably held and rotated with reduced wobbling.

[0053] (3) In the attachment described in (2) above, the sliding part is an O-ring fitted to the fixed part, and the rotating part has an annular part having a surface facing the O-ring, and is configured so that a gap is created between the O-ring and the annular part.

[0054] According to this embodiment, there is a gap between the O-ring and the annular part, and the bristles can be rotated with little force, making it easy to style hair and easy to use. Furthermore, even if the gap becomes smaller due to expansion or deformation of parts caused by heat, the elasticity of the O-ring can absorb the change in rotational force, reducing fluctuations in operating force and making it easy to use.

[0055] (4) In the attachment described in any one of (1) to (3) above, the fixed part has a flow velocity reduction mechanism disposed opposite the suction port.

[0056] According to this aspect, of the kinetic energy term, pressure energy term, and potential energy term in Bernoulli's equation, the kinetic energy term related to velocity can be reduced by the flow rate reduction means and converted into pressure. This makes it possible to reduce and keep constant the outflow amount, particularly from the outlet farthest from the inlet, so that positive ions and / or negative ions can be ejected evenly, and static electricity can be reliably removed from both hair and bristles.

[0057] (5) In the attachment described in any one of (1) to (4) above, the bristles are formed by a charged body, and the attachment is configured, when connected to the dryer, to transmit positive ions and / or negative ions emitted from the dryer to the user's hair that comes into contact with the bristles.

[0058] According to this aspect, it is possible to reduce at least one of the positive ions in the hair and the negative ions in the bristles, thereby reducing damage to the hair caused by friction even when the brush is applied hard to the hair.

[0059] (6) The attachment according to any one of (1) to (5) above, wherein (total area of ​​the air outlets)≦(total area of ​​the air inlets).

[0060] According to this embodiment, since the pressure decreases as the flow path narrows and the flow rate increases (Bernoulli's equation), the pressure at the outlet can be reduced and the pressure at the inlet can be increased. As a result, even if there are multiple outlets, there is no backflow of air from the outlets to the inlet, and the pressure at the outlet can be kept constant everywhere, reducing uneven hair treatment.

[0061] (7) An attachment according to any one of (1) to (6) above, which is provided with a locking mechanism that switches between a rotational state in which the rotating part rotates and a locked state in which the rotating part does not rotate when a predetermined operation is performed.

[0062] According to this embodiment, the hair straightener can be used for both curling and straightening purposes. Furthermore, even if the user desires a complicated hair treatment in which the hair is straightened partway and then curled only at the ends, the treatment can be easily performed without changing the attachment.

[0063] (8) A dryer equipped with an attachment according to any one of (1) to (7) above.

[0064] According to this aspect, the tip can be replaced, making it possible to provide a dryer that is suitable for a variety of hair lengths or hair types.

[0065] (9) The dryer described in (8) above further comprises a throttling section, the throttling section being provided in the air flow path, and (total area of ​​the outlets of the attachment)≦(total area of ​​the throttling section).

[0066] According to this aspect, even if the cross-sectional area cannot be made large due to the blades of the dryer or the vanes of the motor, the pressure at the attachment outlet can be lowered, so there is no backflow of air and air can be blown out efficiently. Of course, this is not the case.
