[0008] Hereinafter, embodiments of the hair dryer disclosed herein will be described with reference to the accompanying drawings. In the drawings, the same or equivalent elements are denoted by the same reference numerals, and repeated descriptions are omitted.

[0009] In this disclosure, the term "hair dryer" refers to any device that dries an object, such as human or animal hair, by blowing air toward it. The temperature of the air blown by a hair dryer is not particularly limited. A hair dryer can, for example, blow cold air or heated air. Hair dryers include devices with both drying functions and those with functions other than drying. For example, a hair dryer may produce a cosmetic effect on the skin or scalp by blowing low-temperature air containing charged particles. Hereinafter, a "hair dryer" may also be referred to simply as a "hair dryer."

[0010] (Implementation 1) Figures 1 to 7 : is a diagram showing the structure of the hair dryer of embodiment 1. Figure 1 It's a stereogram. Figure 2 This is a magnified perspective view of the air outlet. Figure 3 is the main view, Figure 4 It is a top view. Figure 5 It is a side view. Figure 6 This is a cross-sectional view from the front. Figure 7 For the sake of convenience, the direction of the hair dryer 1 is shown as follows: Figure 3 The side shown in FIG) is called the "front side", and the side that does not have an edge along the length direction of the hair dryer body and where the blow-out port is located ( Figure 4 The surface shown in the figure) is called the "top surface", the surface without edges along the length direction of the hair dryer body and without air inlet and air outlet is called the "bottom surface", and the surface with edges along the length direction of the hair dryer body and smaller area ( Figure 5 Hereinafter, in the description of the hair dryer and the hair dryer body, regardless of the orientation of the hair dryer itself, the side closer to the above-mentioned top surface is referred to as "upper" and the side closer to the bottom surface is referred to as "lower".

[0011] First, the outline of the structure of the hair dryer 1 and the flow of air therein will be described. The hair dryer 1 has a hair dryer body in an elongated shape. The hair dryer body includes a housing 10 forming the outer walls of the front, side and bottom surfaces, and devices such as electric blowers 61, 62 and heaters 71, 72 arranged in the housing 10. An air intake 20, a first blow-out port 32 and a second blow-out port 37 are provided on one side of the hair dryer body in the longitudinal direction. The air inhaled from the air intake 20 passes through the air path (space serving as an air flow path) formed in the housing 10 and is blown out from the first blow-out port 32 and the second blow-out port 37. Figure 3 As shown, the hair dryer 1 can be placed with its bottom side facing downward, freestanding relative to a ground surface 8. During use, it can be lifted by grasping the recessed portion 10A, or placed on a ground surface 8 such as a table. To ensure freestanding operation, the bottom surface of the hair dryer 1 is preferably flat. However, since the hair dryer 1 includes two air cylinders, its center of gravity is stable when facing downward, allowing it to stand freestanding even on uneven surfaces. "Freestanding" here means maintaining the dryer body free of any other support along its length. Furthermore, since the hair dryer 1 includes two air cylinders, a recessed portion 10A can be formed between the two cylinders, which is also suitable for forming such a recessed portion 10A.

[0012] Figure 8 This is a cross-sectional view schematically showing an internal air passage of the hair dryer 1 according to the first embodiment. Figure 8The arrow in the figure indicates the direction of wind flow. The air path includes a first air path portion 21 extending from the air inlet 20 to one side in one direction, and a second air path portion 23 arranged parallel to the first air path portion 21 on the inner side of the first air path portion 21 and connected to the first air path portion 21. The directions of wind flow in the first air path portion 21 and the second air path portion 23 arranged in parallel are opposite, and the air path also includes a return portion 22 that changes the direction of the wind flowing in the air path. The first air path portion 21 and the second air path portion 23 are connected by the return portion 22. The return portion 22 is formed at the bottom of the other side portion in the longitudinal direction of the hair dryer body. In order to maintain a distance from the inner wall surface of the shell 10, a spacer can be arranged in the first air path portion 21 and the return portion 22. The spacer can prevent the shell 10 from being bent due to the force of the suction. The spacer can be a rib protruding from the inner wall surface of the shell 10.

[0013] In the hair dryer 1, the air intake 20, first outlet 32, and second outlet 37, which are the primary sources of sound (noise) generated during air flow, are all located on one side of the hair dryer body in the longitudinal direction. In other words, the air intake 20 is located on the same side as the first outlet 32 ​​and second outlet 37, which the person drying their hair (the hair dryer user) faces. As a result, compared to typical hair dryer configurations (where the air intake is located on one side of the hair dryer body and the outlet is located on the other side), the noise source is concentrated on the side closest to the hair dryer user. Therefore, air intake and exhaust noise are less likely to spread widely. Generally, people around the user of the hair dryer 1 have a lower psychological tolerance for noise not generated by them than the user. Therefore, reducing the noise impact on others enhances the commercial value of the hair dryer. Thus, by reducing the noise impact on others around the hair dryer user, the hair dryer 1 of this embodiment can be said to be superior in terms of quietness (low noise performance) compared to hair dryers with these typical configurations.

[0014] In the hair dryer 1, the first air passage 21 is located on a side closer to the housing 10, and the second air passage 23 is located on a side farther from the housing 10. The second air passage 23 is formed within the air cylinders 51 and 56. In this disclosure, the air cylinder 51 is also referred to as the "first housing," and the air cylinder 56 is also referred to as the "second housing." The air passage formed within the air cylinder 51 is referred to as the "first ventilation passage," and the air passage formed within the air cylinder 56 is referred to as the "second ventilation passage." The air cylinders 51 and 56 are made of an airtight material, such as resin or metal. The air cylinders 51 and 56 can be supported by ribs (not shown) disposed within the housing 10 or by support members (not shown) disposed on the folding portion 22.

[0015] Inside the air cylinder 51, an electric blower (first electric blower) 61 and a heater 71 are installed. Inside the air cylinder 56, an electric blower (second electric blower) 62 and a heater 72 are installed. "Electric blower" is a general term for a mechanism that uses electricity to blow air. Electric blowers 61 and 62 cause air to flow from the air intake 20 to the first and second outlets 32 and 37. In the hair dryer 1, electric blowers 61 and 62, like the air intake 20, first and second outlets 32 and 37, are also a major source of noise. In this embodiment, since electric blowers 61 and 62 are located within the air cylinders 51 and 56, which form the second air passage 23 facing away from the housing 10, the multi-layered structure formed by the air cylinders 51 and 56 forming the second air passage 23 and the air layer forming the first air passage 21, as well as sound-absorbing materials located in the first air passage 21, improve quietness. Furthermore, if a sound absorbing material is disposed in the second air passage portion 23 , the quietness can be effectively improved.

[0016] The hair dryer 1 of this embodiment has two air cylinders 51 and 56 and is provided with two second air ducts 23. The number of air cylinders provided in the hair dryer 1 is not particularly limited and can be one (a single air cylinder) or three or more. Increasing the number of air cylinders increases the weight of the hair dryer 1, but while achieving the same air volume, it reduces the load on the single electric blower, thereby improving quietness. The air cylinder 51 (the first housing) and the air cylinder 56 (the second housing) can be in close contact or separated with a sound-absorbing material 26 positioned between them.

[0017] Next, the structure will be described in more detail along the flow direction of air flowing in the hair dryer 1.

[0018] As shown in the figure, a first air path portion 21 is provided around the entire inner side of the housing 10 of the hair dryer body. Sound-absorbing material can be arranged in the first air path portion 21. The upper end opening of the first air path portion 21 is an air intake port 20. The air sucked in from the air intake port 20 flows from the top of the first air path portion 21 to the bottom. The air intake port 20 can be equipped with a filter to prevent the intrusion of foreign matter. As long as the filter can allow air to pass through and capture foreign matter, there is no particular limitation, for example, a rigid body such as a metal part can be used. In the present embodiment, a metal mesh filter (metal mesh) is installed, but for example, a filter can also be composed of a punched metal with a plurality of openings formed in a matrix, or a filter made of metal fibers such as steel wool can be used. The structure of the filter can be lattice-shaped, mesh-shaped, porous, etc. The material of the filter can also be resin instead of metal, and a high-rigidity resin is preferably used.

[0019] The return portion 22 of the air path is provided inside the bottom surface of the housing 10 of the hair dryer body. The return portion 22 of the air path is formed in the space between the lower ends of the air cylinders 51, 56 constituting the second air path portion 23 and the bottom surface of the housing 10.

[0020] In this embodiment, a control board 80 is located in the folded portion 22. The control board 80 receives signals from the operating unit of the hair dryer 1 and from sensors that may be located on the hair dryer body. Based on these signals, the control board 80 outputs signals for controlling devices such as the electric blowers 61, 62 and heaters 71, 72. Because the control board 80 generates a significant amount of heat when processing signals, it is preferably located within the air duct for heat dissipation purposes. Since sound-absorbing material may be located within the first air duct portion 21 and the electric blowers 61, 62 and heaters 71, 72 are located within the second air duct portion 23, it is more preferable to locate the control board 80 within the folded portion 22 of the air duct for spatial considerations. It should be noted that the location of the control board 80 is not limited to the above. For example, the control board 80 may be located on the side of the air cylinders 51, 56, overlapping at least one of the air cylinders 51 and 56. Alternatively, the control board 80 may be located across both the side of the air cylinder 51 and the side of the air cylinder 56. A power supply unit can also be placed in the folded portion 22. Because the power supply unit generates heat when processing signals, it is preferably placed within the air duct for heat dissipation. To mitigate heat generated by devices within the housing 10, the inner walls of the housing can be coated with a flame retardant. Alternatively, a sound-absorbing material placed within the air duct can be made of a flame-retardant material.

[0021] In the central part of the space inside the shell 10 constituting the main body of the hair dryer, air cylinders 51 and 56 constituting the second air path portion 23 are arranged. Electric blowers 61 and 62 and heaters 71 and 72 are arranged inside the air cylinders 51 and 56. In detail, the electric blower 61 and the heater 71 are arranged inside the air cylinder 51, and the electric blower 62 and the heater 72 are arranged inside the air cylinder 56. Electric blowers 61 and 62 and heaters 71 and 72 are provided in each of the multiple air cylinders 51 and 56. The air passing through the second air path portion 23 flows from bottom to top and reaches the first blow-out port 52 and the second blow-out port 57 of the hair dryer main body. The electric blowers 61 and 62 are arranged in the lower part (upstream side of the air flow) inside the air cylinders 51 and 56, and the heaters 71 and 72 are arranged in the upper part (downstream side of the air flow) inside the air cylinders 51 and 56. The method for fixing the electric blowers 61, 62 and the heaters 71, 72 is not particularly limited. For example, they can be fixed by fitting the concave and convex parts formed on the inner surface of the cylinder with the convex parts and / or concave parts of the electric blowers and heaters.

[0022] The electric blowers 61 and 62 can be, for example, a mechanism that uses electricity to rotate a component that generates airflow (such as a fan) to generate airflow, or a mechanism that uses electricity to generate vibrations, etc., to create high and low pressure areas, thereby generating airflow. For example, the electric blowers 61 and 62 preferably include a fan and a motor that drives the fan. The arrangement relationship between the fan and the motor in the direction of flow is not particularly limited. For example, the fan can be arranged upstream and the motor can be arranged downstream.

[0023] As the motor, for example, a brushless motor, an induction motor, a synchronous reluctance motor, etc. are commonly used. Among them, a brushless motor is more preferred, and a brushless DC motor is even more preferred.

[0024] Since brushless motors have no brushes that come into contact with the rotor, they can suppress the noise generated by the brushes contacting the rotor. This allows for a further quieting effect. Brushless motors include, for example, motors in which the excitation permanent magnets are located on the rotor side and the armature windings are located on the stator side; motors in which, instead of switching power using brushes that change the commutator position, sensors (such as Hall sensors) that detect rotor position signals are fed back to the inverter to control power flow. Brushless motors, for example, can also be motors that generate a rotating magnetic field by changing the direction of current using switches such as semiconductor switches, thereby rotating the rotor. It should be noted that induction motors can also be motors that generate a sine wave with a phase offset from the power supply to rotate the magnetic field. A synchronous reluctance motor is a type of synchronous motor that, for example, rotates as an induction motor at startup and rotates synchronously with the power supply frequency during operation.

[0025] The air flowing through the internal flow paths of the air cylinders 51 and 56 can be heated by the heaters 71 and 72, respectively. When the heaters 71 and 72 are in an energized state (referred to as an on state), hot air is blown out from the first outlet 52 and the second outlet 57. When the heaters 71 and 72 are in an off state (referred to as an off state), cold air that has not been heated by the heaters 71 and 72 can be blown out from the first outlet 52 and the second outlet 57. "Heating" means that the temperature of the gas discharged from the area where the heater is installed is higher than the temperature of the gas (e.g., air) before entering the area.

[0026] Each air cylinder 51 and 56 is equipped with a heater 71 or 72 and an electric blower 61 or 62. Therefore, by, for example, varying the output (applied power) of each heater 71 or 72 and the output (e.g., rotational speed) of each electric blower 61 or 62, air of varying temperatures and air volumes can be blown out from the multiple air cylinders 51 and 56. Thus, even when the hair dryer is held in a fixed position and posture, low-temperature air and high-temperature air can be blown alternately to multiple adjacent areas, or high-volume air and low-volume air can be blown alternately to multiple adjacent areas. Furthermore, high-temperature air and high-volume air can be blown alternately to low-temperature air and low-volume air, or high-temperature air and low-volume air can be blown alternately to multiple adjacent areas. This allows, for example, quick-drying properties to be improved while preventing hair damage.

[0027] In addition, in a plurality of flow paths, the electric blowers respectively arranged in two adjacent flow paths may rotate in the same direction or in different directions. The rotation directions of the electric blowers 61 and 62 may be controlled to be the same rotation direction or to be controlled to be opposite rotation directions. For example, the rotation direction of the electric blower 61 and the rotation direction of the electric blower 62 may be controlled so that they are in the same direction for a period of time and in opposite directions for another period of time, and so on alternately. The "rotation direction" here refers to the rotation direction when observed along the flow direction of the flow path in which the electric blower is provided. The rotation direction includes clockwise (right rotation) and counterclockwise (left rotation).

[0028] For example, by rotating the electric blower 61 in opposite directions to the electric blower 62, the phase of the sound produced by the electric blower 61 can be made different or opposite to that of the sound produced by the electric blower 62. This can cancel out the sound and vibration produced by each electric blower, further reducing noise and vibration of the hair dryer 1. In particular, the fans of the electric blowers in two adjacent flow paths are preferably symmetrical in shape. The two electric blowers can rotate in the same or opposite directions.

[0029] The above description describes a structure in which an electric blower and a heater are provided in each of a plurality of flow paths, but the present invention is not limited to this structure. For example, it is preferred to provide an electric blower in at least two of the plurality of flow paths. When 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 plurality of flow paths. A heater is not necessarily provided in each of the plurality of flow paths. It is preferred to configure a heater in at least two of the plurality of flow paths in which an electric blower is provided. However, a heater may not be provided in a part of the at least two flow paths in which an electric blower is provided. In addition, a plurality of electric blowers may be provided in one flow path, and a plurality of heaters may also be provided.

[0030] Figure 9 This is a perspective view of the hair dryer according to Embodiment 1, with the outlet attachment removed. The hair dryer body includes multiple outlets, including a first outlet 52 and a second outlet 57. The outlet attachments (blowing attachments) are attached to the first outlet 52 and the second outlet 57, forming the hair dryer's outlet. To enhance air intake, the area between the first outlet 52 and the second outlet 57 can be used as an air intake vent 20.

[0031] A structure for mounting a blow-out accessory described later (blow-out accessory mounting portion) may be formed on the first blow-out outlet 52 and the second blow-out outlet 57. For example, the blow-out accessories may be fixed by fitting the convex and concave portions formed on the inner surfaces of the first blow-out outlet 52 and the second blow-out outlet 57 into the convex and / or concave portions of the blow-out accessory. The accessory and the hair dryer body may be detachably arranged, for example, by magnetic force. Specifically, for example, a magnet (including an electromagnet) may be arranged on at least one of the accessory and the hair dryer body, and a magnetic body (for example, a weak magnetic body) may be arranged on the side of the accessory and the hair dryer body where no magnet is arranged. It should be noted that various types of accessories may be loaded and unloaded on the hair dryer body.

[0032] The hair dryer 1 includes a first blow-out section 31 and a second blow-out section 36. The first blow-out section 31 includes a first blow-out port 32, and the second blow-out section 36 includes a second blow-out port 37. In other words, the hair dryer 1 may include multiple blow-out ports, including the first blow-out port 32 and the second blow-out port 37. Because the first blow-out section 31 and the second blow-out section 36 protrude from the top of the hair dryer body, the first blow-out port 32 and the second blow-out port 37 are located above the air intake port 20. The first blow-out section 31 and the second blow-out section 36 consist of blow-out attachments that are detachable from the hair dryer body. The blow-out attachment, for example, is a cylindrical component made of an airtight material with an interior defining an air path (a space serving as an air flow path). Multiple blow-out attachments can be used for each blow-out outlet, or a blow-out attachment with two or more blow-out outlets can be used. The blow-out attachments make it easy to change the opening direction of the blow-out outlet. The air intake port can also be comprised of an attachment that is detachable from the hair dryer main body. The hair dryer 1 can include a variety of attachments, and the blow-out and air intake ports can be appropriately replaced as needed. For example, each of the multiple attachments can be rotatably mounted on the hair dryer main body about a rotation axis extending along the length of the hair dryer main body.

[0033] The opening directions of the first blow-out port 32 and the second blow-out port 37 can be set to be rotatable. When the first blow-out port 32 and the second blow-out port 37 are composed of blow-out accessories, the first blow-out portion 31 and the second blow-out portion 36 are rotatably connected, so that the opening directions of the first blow-out port 32 and the second blow-out port 37 can be easily rotated. For example, the blow-out accessories can rotate around Figure 3 The axes (central axes of the air passages) AX1 and AX2 (in the plan view) shown in FIG. Figure 3 The rotatable blower attachment can be locked and rotated at any angle. The rotatable angle is not particularly limited, for example, 0 to 360 degrees.

[0034] When the opening directions of the first and second blow-out ports 32, 37 are rotatable, the hair dryer 1 is preferably used in conjunction with a distance sensor that measures the distance between the hair dryer 1 and the hair to be dried. By controlling the angle or rotation direction of the first and second blow-out ports 31, 36 based on the distance to the hair as measured by the distance sensor, the performance of the hair dryer 1 can be improved.

[0035] The first and second blower sections 31, 36 are spaced apart from each other. Furthermore, they are arranged parallel to each other. This spacing prevents the airflow from the first and second blower sections 31, 36 from immediately merging, effectively creating the "drape phenomenon" described below. Consequently, the airflow from the hair dryer 1 is efficiently delivered to the hair. The area between the first and second blower sections 31, 36 (more precisely, between the first and second outlets 32, 37) is a closed area where no air is delivered.

[0036] The "wrinkle phenomenon" refers to the phenomenon in which hair appears wavy in the area opposite the hair dryer 1 when the hair dryer 1 blows air. For example, when drying hair, when the hair dryer 1 is turned on and air is blown out of the first and second outlets 32, 37, radial high-velocity areas are formed from the first and second outlets 32, 37. Meanwhile, the area between the first and second outlets 32, 37 is a closed area where no air is supplied. However, the air in this closed area is drawn into the high-velocity area, creating a low-velocity area between the first and second outlets 32, 37 where air flows toward the hair. This formation of low-velocity areas between the high-velocity areas generates turbulence in the blown air, creating swirling turbulence in the low-velocity areas. This turbulence can lift the hair, allowing for faster drying. Furthermore, the wind blown out from the first outlet 32 ​​and the second outlet 37 hits the scalp and then rebounds, generating wind in a low wind speed area that causes the hair to move away from the scalp and other parts, thereby further generating turbulence.

[0037] Hair blown by air in the high-velocity zone is pressed against the scalp (head) by the wind pressure. In contrast, hair in the turbulent low-velocity zone is swept up by the turbulent flow and lifted off the scalp (head). As a result, the hair appears to waver in the area facing the hair dryer 1. In this disclosure, this phenomenon is referred to as the "wrinkle phenomenon." Furthermore, the wind that produces the high- and low-velocity zones that cause the "wrinkle phenomenon" is also referred to as "wrinkle wind."

[0038] The distance between the first blower 31 and the second blower 36 is preferably large enough to fit around the head, hair, or hand. This allows for a more effective "wrinkle effect" and enhances the hair-holding effect described below. For example, the maximum distance between the first blower 31 and the second blower 36 is preferably 10 mm to 100 mm. Furthermore, to ensure that the first and second blower outlets 32 and 37 hold hair, the distance between the first and second blower 31 and 36 is preferably adjusted.

[0039] In the hair dryer 1, the air inlet and the air outlet may be opened in different directions or in the same direction. Figure 1 In the illustrated hair dryer 1, the air intake port 20 opens in different directions from the first and second air outlets 32 and 37. Specifically, the air intake port 20 is oriented along the length of the hair dryer body, while the first and second air outlets 32 and 37 are oriented parallel to the top of the hair dryer body. Therefore, the opening direction of the air intake port 20 of the hair dryer 1 is perpendicular to the opening directions of the hair dryer's air outlets (the first and second air outlets 32 and 37). When the air intake port 20 and the air outlets are perpendicular, the air intake port 20 can be oriented upward or downward, which is typically not the case. This prevents the lateral propagation of the blowing noise from the hair dryer 1. Consequently, the noise is less likely to propagate to people (other people) besides the hair dryer user, minimizing the risk of causing distress to others.

[0040] The hair dryer 1 may also not include a blow-out attachment. Figure 1 The accessories are shown in the removed state (i.e. Figure 9 Use in the state shown). Figure 9 In the illustrated state, the air intake port 20 and the air outlet of the hair dryer face the same direction. Specifically, the air intake port 20, the first air outlet 52, and the second air outlet 57 face the same direction along the length of the hair dryer body. Since the air intake port 20 and the air outlet face the same direction, the inhalation and exhaust noises are directed in the same direction, thus preventing the noise from spreading widely.

[0041] Alternatively, the detachable blow-out attachment may not be provided. Figure 1 The first blowing part 31 and the second blowing part 36 of the shape shown are integrally formed with the hair dryer body. The blowing attachment can also be fixed to the hair dryer body in an inseparable manner.

[0042] The hair dryer 1 of the first embodiment has a recess 10A provided in the housing 10 constituting the main body of the hair dryer. The recess 10A is recessed in the second direction (front direction) when viewed from the second direction (the longitudinal direction of the housing 10) perpendicular to the first direction in which the first air duct 21 and the second air duct 23 extend. The recess 10A may be provided only in the second direction. Figure 3 On the front side as shown, but preferably on both the front and back sides ( Figure 3 (The opposite side of the front view shown). The hair dryer 1 of Embodiment 1 lacks a handle like a gun-type hair dryer (a hair dryer comprising a main body of a hair dryer with an electric blower and heater, and a handle connected thereto, forming a T-shape when viewed from the side). Therefore, it offers excellent design and storage capabilities. Furthermore, the provision of recessed portion 10A makes gripping the main body of the hair dryer easier, improving operability. Roughening the surface of recessed portion 10A further enhances gripping convenience. Figure 10 This is a front view showing a state in which a user holds the hair dryer according to the first embodiment. Figure 11 This is a plan view showing a state in which a user holds the hair dryer according to the first embodiment.

[0043] The placement and shape of recess 10A are not particularly limited, but it is preferably elongated along the length of the elongated housing 10. Furthermore, since the motors in electric blowers 61 and 62 within the hair dryer body are relatively heavy, recess 10A is preferably positioned in the first direction (the lengthwise direction of housing 10) to coincide with the motors' position, in order to position recess 10A close to the center of gravity of the hair dryer 1. Furthermore, since the hair dryer 1 includes two air cylinders, each housing a motor, recess 10A is preferably located between air cylinders 51 and 56.

[0044] The depth of the recess 10A is preferably such that a person's fingers can grasp it, for example, 5 mm or more and 20 mm or less. The length D1 of the recess 10A in the longitudinal direction is preferably close to the width D2 of the index finger F2 to the little finger F5 of a person (the sum of the widths of the index finger F2, the middle finger F3, the ring finger F4, and the little finger F5), for example, 60 mm or more. In addition, when the housing 10 is held from the side so that a finger can fit into the recess 10A, as shown in FIG. Figure 11 As shown, the length D3 between the recess 10A where the tip of the thumb F1 is located and the recess 10A where the tip of the index finger F2 is located is preferably close to half the outer circumference of the housing 10. For example, half the outer circumference is preferably less than 170 mm. In this case, the distance D4 between the recess 10A and the side surface of the housing 10 is preferably less than half of 170 mm. When the recessed portion 10A is provided on both the front and back surfaces, the position, shape, and size of the recessed portion 10A formed on each surface may be the same or different.

[0045] When the recess 10A is positioned along the first direction (the longitudinal direction of the housing 10), the hair dryer 1's air outlets (the first air outlet 32 ​​and the second air outlet 37) preferably open in a direction oblique to the first direction. The direction oblique to the first direction can be, for example, a direction perpendicular to the first direction. This relationship between the recess 10A and the air outlet improves the operability of the hair dryer.

[0046] Figure 12 and Figure 13 1 is a diagram showing a state where the hair dryer of Embodiment 1 is placed on a stand. Figure 12 It's a stereogram. Figure 13 It is a top view. Figure 14 This is a perspective view showing the connection between the stand and the power cord. The hair dryer 1 of Embodiment 1 includes terminals for connection to the stand 110. As shown in the figure, the stand 110 can also be connected to a power cord 120. The power cord 120 is not particularly limited as long as it provides an electrical connection between an external power source and the hair dryer body. It can also be a power cord for supplying signals to control the hair dryer 1.

[0047] The bracket 110 is used as a support for placing the hair dryer body. It is preferred that the hair dryer body be placed on the bracket 110 so that the whole body can stand on its own. For example, the bracket 110 has a flat grounding surface. By making the grounding surface contact with a table surface, the bracket 110 and the hair dryer body can be placed on their own and grounded. Figure 12 As shown, the hair dryer body can be kept ungrounded along its length simply by being integrated. Furthermore, as shown in the figure, when the hair dryer body and the power cord 120 are electrically connected via the bracket 110, the bracket 110 may include a terminal (power connector) 112 for electrically connecting to the hair dryer body and a terminal 113 for electrically connecting to the power cord 120. For example, the bracket 110 may include a grounding surface, a flat surface (seat) 111 located opposite the grounding surface and for placing the hair dryer body, and a terminal (power connector) 112 protruding from the flat surface 111 and for electrically connecting to the hair dryer body.

[0048] The hair dryer 1 can also be used with the hair dryer body placed on a stand 110. In this case, when the hair dryer body is placed free-standing on the stand 110, the opening direction of the hair dryer's air outlet is preferably diagonally upward. This allows the air blown by the hair dryer 1 to be properly directed onto the object being dried, even when placed on a table lower than the head (the object being dried). Furthermore, to prevent the hair dryer body from tipping backward (toward the back) due to the reaction force of the air blown out during air delivery, it is desirable to optimize the shape of the stand 110's ground contact surface and the positional relationship between the hair dryer body's center of gravity and the ground contact surface when the hair dryer is free-standing. For example, the stand 110's ground contact surface preferably extends long in the direction behind the hair dryer body, opposite the air outlet. Furthermore, the stand 110 may be provided with a support plate or rod to prevent the hair dryer body from tipping backward. The center of gravity of the hair dryer body and the ground contact surface are preferably as close as possible. For example, when the hair dryer body is placed free-standing on the stand 110, the hair dryer body is preferably constructed so that the electric blower is as close to the ground contact surface as possible. Furthermore, by optimizing the shape of the ground contact surface of the stand 110 and the positional relationship between the center of gravity of the hair dryer body and the ground contact surface in a free-standing state, the hair dryer 1 can prevent the hair dryer body from falling backward during air supply.

[0049] Figure 15 This is a perspective view showing the hair dryer of Embodiment 1 directly connected to a power cord. As shown in the figure, the hair dryer 1 of Embodiment 1 may also include a terminal 100 on the hair dryer body for direct connection to a power cord 120. The terminal connected to the stand 110 may also serve as a terminal for direct connection to the power cord 120. In this case, the hair dryer 1 of Embodiment 1 is compatible with both the connection to the stand 110 and the direct connection to the power cord 120.

[0050] The hair dryer 1 may also be a hair dryer body fixedly connected to the power cord 120, and the bracket 110 is just a simple support stand independent of the power cord 120. In this case, it is preferable to have the following structures (1) and (2). (1) The bracket 110 has a flat surface portion (seat surface) for placing the hair dryer body. (2) The seat surface of the bracket 110 is tilted relative to the normal direction of the placement surface such as a desktop. According to the above structure (2), the tilted seat surface can make it easier for the wind to blow on the hair of the hair dryer user.

[0051] When the hair dryer body is detachably connected to the power cord 120, in addition to the above-mentioned structures (1) and (2), it is preferred to have at least one of the following structures (3) to (5). (3) Connect the terminal 100 provided at the lower portion of the hair dryer body to the power connector 112 on the seat surface of the bracket 110 to supply power. (4) The power cord 120 and the bracket 110 are detachable. (5) The hair dryer 1 can be charged by supplying power via the power cord 120 . According to the above configuration (4), it is possible to use both a method of connecting the power cord 120 to the bracket 110 and a method of connecting the power cord 120 to the hair dryer body.

[0052] In the hair dryer 1 of Embodiment 1, the operating unit may be provided on the hair dryer body or externally. Examples of externally provided operating units include providing the operating unit on the power cord or providing a remote control connectable via communication means such as Bluetooth (registered trademark). The remote control may also be a communication terminal such as a smartphone.

[0053] Figure 16 This diagram illustrates the configuration of an operating unit on the power cord. Operating unit 130 includes, for example, an air volume switch button 130A for adjusting the air volume, a mode switch button 130B for switching between multiple preset air supply modes, a warm / cold switch button 130C for adjusting the air temperature, and a power switch 130D for switching the hair dryer main unit on and off. The power supply board can be located within operating unit 130 or elsewhere.

[0054] When the hair dryer body is fixedly connected to the power cord 120, the operation is preferably performed through the operating portion 130 provided on the power cord 120. Furthermore, when the hair dryer body is detachably connected to the power cord 120, the preferred operating methods include: connecting the power cord 120 to the terminal 100 provided at the lower portion of the hair dryer body and then operating the hair dryer body through the operating portion 130; or connecting the power cord 120 to the bracket 110 on which the hair dryer body is placed and then operating the hair dryer body through the operating portion 130.

[0055] like Figure 12 As shown in FIG. 1 , the hair dryer 1 including the bracket 110 is designed to be able to stand on its own. Specifically, the hair dryer 1 is designed as follows Figure 12 The hair dryer 1 can be used in a self-standing position. Therefore, for example, the user of the hair dryer 1 can dry their hair without having to hold the hair dryer 1 in their hands. This reduces the burden on the user when drying their hair. The self-standing design of the hair dryer 1 in this embodiment is particularly effective when drying hair that is long or when the air temperature of the hair dryer 1 is set to a low level, resulting in a longer drying time.

[0056] If the hair dryer 1 is designed to be usable even when mounted on the bracket 110, the grounding surface 110a of the bracket 110 is preferably larger than Figure 5 The area of ​​the flat portion on one side (lower side) of the hair dryer body in the longitudinal direction is shown in FIG. This is because in this case, the posture of the hair dryer 1 during use can be made more stable.

[0057] In the hair dryer 1 of the present disclosure, the shape of the blow-out port is not particularly limited. Figure 17 and Figure 18 The shape of the blowout port and the shape of the attachment are shown.

[0058] (Implementation Method 2) The hair dryer of the second embodiment shows an example in which the structure of the blow-out attachment is different from that of the first blow-out port 32 and the second blow-out port 37 of the first embodiment. Figure 17 This is a perspective view of the structure of the hair dryer according to the second embodiment. Figure 18 Is the enlarged display Figure 17 Figure of the blow-out attachment shown. Figure 18 The arrows in the figure indicate the direction of air blown out of the hair dryer. The blower attachment of this embodiment includes a first blower portion 131 with a first annular blower outlet 132 and a second blower portion 136 with a second annular blower outlet 137, capable of blowing air along the length of the hair dryer body. In the hair dryer 2 of this embodiment, the air intake 20 and the blower outlets (first blower outlet 132 and second blower outlet 137) face the same direction.

[0059] (Implementation 3) In the hair dryer disclosed herein, there are no particular restrictions on whether or not a blow-out attachment or a recessed portion in the housing is provided. The hair dryer of Embodiment 3 differs from the hair dryer 1 of Embodiment 1 in that it lacks a blow-out attachment or a recessed portion in the housing. Furthermore, the hair dryer of Embodiment 3 differs from the hair dryer 1 of Embodiment 1 in the structure for securing the air cylinders 51 and 56. Figures 19 to 23 : is a diagram showing the structure of a hair dryer according to Embodiment 3. Figure 19 is the main view, Figure 20 It is a top view. Figure 21 This is a cross-sectional view from the front. Figure 22 This is a cross-sectional view when viewed from the side. Figure 23 It is a perspective view showing the structure of a support member that supports the air cylinder.

[0060] The hair dryer 3 of the third embodiment includes a support member 90 disposed inside the bottom surface of the housing 210 of the hair dryer body for supporting the air cylinders 51 and 56 , and forming the return portion 22 of the air path. The support member 90 includes an upper portion 91 having an opening corresponding to the second air duct portion 23, a lower portion 92 in contact with the bottom surface of the housing 210, and a plurality of bridge portions 93 connecting the upper portion and the lower portion at intervals. The space between the upper portion 91 and the lower portion 92 constitutes the return portion 22 of the air duct. The control substrate 80 is arranged in the space surrounded by the upper portion 91, the lower portion 92, and the plurality of bridge portions 93. The air flowing in from the first air duct portion 21 flows from the outside to the inside, passes through the opening 94 formed in the upper portion 91 of the support member 90, and flows into the air cylinders 51 and 56 forming the second air duct portion 23. In other words, the return portion 22 of the air duct is formed in the space between the lower ends of the air cylinders 51 and 56 and the bottom surface of the housing 210, and the air cylinders 51 and 56 form the second air duct portion 23. It should be noted that the support member 90 can also be applied to the hair dryer 1 of embodiment 1. The shape of the support member 90 is designed to match the shape of the inner bottom surface of the housing 10 in embodiment 1 so that it can support the air cylinders 51 and 56 in embodiment 1.

[0061] (Implementation 4) Figure 24-27 : is a diagram showing the structure of a hair dryer according to a fourth embodiment. Figure 24 is the main view, Figure 25 It is a top view. Figure 26 This is a cross-sectional view from the front. Figure 27 The hair dryer of the fourth embodiment differs from the hair dryer of the third embodiment in that a blow-out attachment is provided and a cover member covering the blow-out port is provided.

[0062] In this embodiment, the blower attachment is a curved cylindrical component, with its air intake and air outlet openings facing different directions. While the air flow from the main blower outlets 252 and 257 is parallel to the length of the hair dryer body, the wind from the hair dryer 4's outlet, after passing through the cranked air path formed by the blower attachment, is directed perpendicularly to the length of the hair dryer body, toward the front of the hair dryer body. By forming the hair dryer 4's outlet with the blower attachment, the outlet's opening direction and shape can be customized based on how the hair dryer 4 is used, thereby enhancing the user-friendliness of the hair dryer 4. The curved shape of the blower attachment provides a certain length in the blowing direction, thus providing excellent airflow regulation.

[0063] The blow-out attachment includes a first barrel 231 having a first air intake port and a first blow-out port 232, and a second barrel 236 having a second air intake port and a second blow-out port 237. The first barrel 231 is a cylindrical component with a space inside, and sucks air from the first air intake port connected to the main blow-out port 252 of the hair dryer body, and blows the sucked air to the outside from the first blow-out port 232. The second barrel 236 is a cylindrical component with a space inside, and sucks air from the second air intake port connected to the main blow-out port 257 of the hair dryer body, and blows the sucked air to the outside from the second blow-out port 237. In this embodiment, the first barrel 231 and the second barrel 236 are independent components that can be replaced separately, but the blow-out attachment can also be a component in which the first barrel 231 and the second barrel 236 are combined together. Sound-absorbing material can be set inside the first barrel 231 and the second barrel 236.

[0064] There is no particular limitation on the shape of the first outlet 232 and the second outlet 237 of the blower attachment, and they may be, for example, circular, elliptical, oblong, polygonal, etc. Furthermore, there is no particular limitation on the size of the first outlet 232 and the second outlet 237 of the blower attachment, and they may be the same size as the first air inlet and the second air inlet, or smaller than the first air inlet and the second air inlet, or larger than the first air inlet and the second air inlet.

[0065] From the perspective of wind rectification, the front ends of the first cylinder 231 and the second cylinder 236, that is, the first blowing outlet 232 and the second blowing outlet 237, should be as long as possible in the front direction. They can protrude from the front of the hair dryer body, but from the perspective of storage, they preferably do not protrude from the front of the hair dryer body.

[0066] It should be noted that the blow-out accessories can be Figure 24 The axes (central axes of the air passages) AX3 and AX4 (in the plan view) shown in FIG. Figure 24 The rotatable blower attachment can be locked and rotated at any angle. The rotatable angle is not particularly limited, for example, 0-360 degrees.

[0067] Alternatively, the detachable blow-out attachment may not be provided. Figure 24 The first barrel 231 and the second barrel 236 of the shape shown are integrally formed with the hair dryer body.

[0068] The first and second barrels 231, 236 of the blower attachment each can be fitted with a cover member 234 to cover the blowout outlet. The cover member 234 allows the shape and size of the blowout outlet of the hair dryer 4 to be adjusted based on the intended use of the hair dryer 4, thereby enhancing the user experience of the hair dryer. The cover member 234 can be a separate component that can be removed from the first and second barrels 231, 236, or it can be integrally integrated with the first and second barrels 231, 236. Furthermore, the cover member 234 can rotate about the center point of the first and second blowout outlets 232, 237. Rotating the cover member 234 allows the distance between the two blowout outlets of the hair dryer 4 to be adjusted, allowing for different drying methods. When the two blowout outlets of the hair dryer 4 are close together, the two airflows can be combined, delivering a stronger airflow within a smaller area. Conversely, when the two blowout outlets of the hair dryer are farther apart, airflow can be delivered over a wider area. In particular, when different air volume controls are performed on a plurality of air cylinders, it is preferable to increase the distance between the two air outlets of the hair dryer in order to utilize two air flows separately.

[0069] Figures 28-36 235 is a top view schematic diagram showing an example of an opening pattern of a cover member covering the blow-out port. In the opening pattern 235 shown, a small-diameter opening is beneficial for reducing the area of ​​the hair dryer blow-out port through the cover member 234, thereby increasing the wind speed. For example, an opening pattern in which the ratio of the area of ​​the opening portion to the total area of ​​the cover member 234 (including the area of ​​the opening portion) is greater than 1:2 and less than 1:6 is more suitable. A more preferred lower limit of this ratio is 1:3, and a more preferred upper limit is 1:5. Specific examples of small-diameter openings include: Figure 28 The central circular opening shown, and Figure 29 Circular opening shown off-center. Figure 28 and Figure 29 The ratio of the openings in the openings is in the range of 1:3-1:5, which is a more ideal opening pattern. Figure 30 The central circular opening shown, or Figure 31 The opening pattern shown consists of a centrally located circular opening divided into two parts by spokes. Figure 30 The opening area in is Figure 28 The ratio is in the range of 1:2-1:5.

[0070] The shape of the opening may not be substantially circular, for example, it may be Figure 32 The quadrilateral opening shown, Figure 33 The curved generally rectangular opening shown, Figure 34 The multiple openings shown are arranged in two rows in a ring shape (the inner side is circular and the outer side is rectangular).

[0071] Other examples of the opening pattern 235 include Figure 35 The semicircular opening shown, Figure 36 A generally annular opening is shown divided into two parts.

[0072] (Implementation 5) Figure 37 1 is a cross-sectional view schematically showing an internal air passage of a hair dryer according to Embodiment 5. The hair dryer according to Embodiment 5 differs from the hair dryer 1 according to Embodiment 1 in that a sound absorbing material is provided in the air passage.

[0073] In the present embodiment, a sound-absorbing material 26 is provided in the air path. Since the hair dryer disclosed in the present invention has an air path including a first air path portion, a second air path portion and a folding portion, a longer air path can be formed compared to a hair dryer of a conventional structure (the air intake port is provided on one side portion in the length direction of the hair dryer main body, and the air outlet port is provided on the other side portion in the length direction of the hair dryer main body). Taking advantage of this, by arranging the sound-absorbing material 26 in the air path, the sound-absorbing material 26 can effectively absorb noise. Therefore, by arranging the sound-absorbing material 26 along the long air path, the quietness can be further improved; or while miniaturizing the hair dryer main body, the length of the air path can be ensured, thereby taking into account both the miniaturization and quietness of the hair dryer main body. Figure 37 In the embodiment, the sound absorbing material 26 is provided on the entire circumference of the inner wall of the housing 10 from the vicinity of the air intake port to before the folded portion 22 .

[0074] The sound-absorbing material 26 is preferably a sheet-like material composed of a plurality of fibers, such as woven or non-woven fabric. The type of sound-absorbing material 26 is not particularly limited; porous materials such as resin porous materials (sponge) and ceramic porous materials may also be used. As a countermeasure to heat generation from equipment located within the housing 10, the sound-absorbing material 26 may also be made of a flame-retardant material.

[0075] The sound absorbing material 26 can be arranged in the first air passage portion 21, in the folding portion 22, in the second air passage portion 23, or in both the first air passage portion 21 and the second air passage portion 23. The longer the air passage length in which the sound absorbing material 26 is arranged, the easier it is to improve the sound absorption characteristics and the more conducive it is to improving the quietness. In addition, the outer sides of the air cylinder 51 forming the first ventilation passage and the air cylinder 56 forming the second ventilation passage are covered with the sound absorbing material 26. Figure 37 In the embodiment, a portion of the sound-absorbing material 26 covering the air cylinders 51 and 56 is exposed from the outside of the housing 10 near the first and second outlets 52 and 57 of the hair dryer body. Alternatively, the sound-absorbing material 26 may cover at least a portion of the outside of the housing 10 (the bottom and side surfaces). With such a structure, the sound-absorbing material 26 can improve the impact resistance of the device. From the perspective of air intake efficiency, it is preferable not to arrange the sound-absorbing material 26 in the portion where the air path is thinner. For example, a structure can be adopted in which the sound-absorbing material 26 is not arranged inside the recess of the shell 10 in the first air path portion 21, or a structure can be adopted in which the sound-absorbing material 26 is arranged only on the side of the first air path portion 21 close to the bottom surface. Alternatively, a thinner sound-absorbing material 26 can be arranged inside the recess than in other portions.

[0076] As shown in the figure, sound absorbing material 26 is arranged along the inner surface of housing 10. The placement of sound absorbing material 26 is not particularly limited as long as it is within the air path. It can also be arranged along the inner surface of air cylinders 51, 56 with electric blowers 61, 62 installed therein, or fill the entire air path.

[0077] From the perspective of preventing the sound-absorbing material 26 from being displaced or falling off, it is preferably fixed in the air path. The ends of the sound-absorbing material 26 and the parts located at locations where the wind is stronger can be connected to the shell 10 using fasteners such as adhesives and screws. Since the adhesive impregnating the sound-absorbing material 26 may cause the sound absorption performance to deteriorate, it is preferably fixed by mechanical means. When sticking the sound-absorbing material 26 to the shell 10, it is preferably not to apply the adhesive to the entire surface of the sound-absorbing material 26. For example, it can be applied in a stripe or grid shape. From the perspective of preventing the sound-absorbing material 26 from falling off, it is preferably to apply the adhesive to at least the edge portion of the sound-absorbing material 26. Depending on the configuration position of the sound-absorbing material 26, a protruding stopper 11 can also be provided on the inner surface of the shell 10 to limit the position of the sound-absorbing material 26. The provision of the stopper 11 can prevent the sound-absorbing material 26 from rolling up and falling off due to the force of the suction. When the sound absorbing material 26 is an aggregate of multiple fibers and parts thereof are easily scattered by wind, the sound absorbing material 26 can be accommodated in a mesh retaining member and then installed in the air path, and the sound absorbing material 26 can be fixed by fixing the retaining member.

[0078] (Implementation 6) In the hair dryer disclosed herein, the arrangement of the air inlet and the air outlet on the hair dryer body is not particularly limited. The hair dryer of embodiment 6 differs from the hair dryer 1 of embodiment 1 in that the arrangement of the air inlet and the air outlet on the hair dryer body is different. Figure 38 This is a cross-sectional view of a hair dryer main body of a hair dryer according to a sixth embodiment as viewed from above. Figure 39 This is a cross-sectional view of the blow-out attachment of the hair dryer according to the sixth embodiment, as seen from above. Figure 40 This is a cross-sectional view schematically showing an internal air passage of a hair dryer according to a sixth embodiment.

[0079] In embodiment 1, the air intake port 20 is arranged on the top of the hair dryer body along the outer periphery of the shell 10, and the blowing outlets (the first blowing outlet 52 and the second blowing outlet 57) are arranged on the inner side, while in this embodiment, the air intake port 20 is arranged on one side on the top of the hair dryer body, and the blowing outlets (the first blowing outlet 52 and the second blowing outlet 57) are separately arranged on the other side. In the upper surface of the hair dryer body, when the air inlet 20 is arranged on the front side and the first blow-out port 52 and the second blow-out port 57 are arranged on the back side, as shown in FIG. Figure 40 As shown, the curved first barrel 231 does not protrude from the front of the housing 210, thereby improving the storage of the hair dryer. Furthermore, when the air intake 20 is located on the rear side and the first and second air outlets 52, 57 are separately located on the front side of the hair dryer body, the distance between the air intake 20 and the first and second air outlets 52, 57 can be increased, thereby preventing the air flow from being affected by a short circuit between the air intake and the air outlet in the hair dryer.

[0080] In addition, since the air inlet 20 on the upper side of the hair dryer body is arranged on one side, the width of the air inlet 20 and the first air path portion 21 adjacent to the housing 10 side is increased. In this way, the air intake amount on the housing 10 side is increased, so Figure 40 As shown, when the control substrate 80 is arranged on the side of the first air passage portion 21, higher cooling efficiency can be obtained.

[0081] (Implementation 7) Figure 41 It is a perspective view showing the structure of a hair dryer according to a seventh embodiment. Figure 42 2 is a cross-sectional view schematically showing an internal air passage of a hair dryer according to Embodiment 7. The hair dryer according to Embodiment 7 differs from the hair dryer 1 according to Embodiment 1 in that the air intake and air outlet of the hair dryer body are at different heights.

[0082] like Figure 41 As shown, the hair dryer of Embodiment 7 has an air intake port 20 provided in the lower portion 318 of the housing, and a first air outlet 52 and a second air outlet 57 provided in the upper portion 320 of the housing. This position of the air intake port 20 is lower than the first and second air outlets 52, 57, increasing the distance between the air intake port 20 and the first and second air outlets 52, 57. As a result, the air flow produced by the hair dryer can be prevented from being affected by a short circuit between the air intake and the air discharge.

[0083] (Implementation 8) Figure 43This is a perspective view showing an enlarged view of the blowout port of a hair dryer according to Embodiment 8. The hair dryer according to Embodiment 8 differs from the hair dryer 1 according to Embodiment 1 in that an air intake port 420 is provided not only on the top of the hair dryer body but also on the upper side of the housing 418. This additional air intake port 420, located farther from the first and second blowout ports 52, 57 than the air intake port 20, and opening in a different direction from the first and second blowout ports 52, 57, reduces short-circuiting between the air intake and the air output of the hair dryer, preventing such short-circuiting from affecting the air flow from the hair dryer.

[0084] (Implementation 9) The hair dryer of the present disclosure is not limited to a type capable of being placed independently relative to a ground surface. Figure 44 This is a cross-sectional view schematically illustrating the internal air flow path of a hair dryer according to a ninth embodiment. The hair dryer according to this ninth embodiment is a so-called gun-type hair dryer comprising a hair dryer body containing an electric blower and a heater, and a handle 15 connected to the body. The handle 15 forms a T-shape when viewed from the side. In the hair dryer according to this ninth embodiment, the air intake 20 and first air outlet 52, which are the primary sources of sound (noise) generated during air flow, are located on one side of the hair dryer body. This reduces noise concentration to the side closest to the user, compared to conventional hair dryers (where the air intake is located on one side and the air outlet is located on the other side). Consequently, the hair dryer according to this embodiment is superior to conventional hair dryers in terms of quietness.

[0085] The hair dryer in this embodiment is a single-cylinder model, but it can also be equipped with two or more cylinders. For ease of use, when using two cylinders, the handle 15 is preferably positioned between the two cylinders. Increasing the number of cylinders increases the weight of the hair dryer, but while maintaining the same air volume, it reduces the load on the single electric blower, thereby improving quietness.

[0086] (Implementation 10) Figure 45This is a perspective diagram showing the structure of a hair dryer according to Embodiment 10. The hair dryer according to Embodiment 10 differs from the hair dryer 1 according to Embodiment 1 in that the hair dryer body is directly connected to a power cord 120, and the power cord 120 is variably oriented relative to the hair dryer body. This variability in the power cord 120's orientation relative to the hair dryer body allows the hair dryer to adapt to various usage styles. For example, when the hair dryer body (housing 10) is placed with its bottom side facing downward, the power cord 120 preferably extends from the back; when the hair dryer body is placed flat with its front side facing downward, the power cord 120 preferably extends from the bottom. Furthermore, the power cord 120 is preferably variably oriented, ranging from extending from the back, opposite the direction of air blowing from the hair dryer's air outlet, to extending from the bottom. This prevents the power cord 120 from interfering with the user's drying process.

[0087] (Implementation 11) Figure 46 This is a perspective view showing the structure of a hair dryer according to Embodiment 11. The hair dryer according to Embodiment 11 differs from the hair dryer 1 according to Embodiment 1 in that a belt 550 is attached to the side of the housing to secure the hair dryer. Belt 550 can be made of a stretchable material such as rubber or a design-friendly material such as leather.

[0088] (Implementation 12) In Embodiment 1, the filter that prevents foreign matter from entering the air intake port is made of a rigid material such as metal. However, the filter can also be made of a flexible material, such as resin. The filter structure can be lattice-shaped, mesh-shaped, or porous. Examples of porous resin bodies include sponges and non-woven fabric filters.

[0089] Hereinafter, another example of the second hair dryer of the present disclosure will be described. In the following description, for components using the same terms as those in the above embodiment, the description in the above embodiment can be cited. It is expected that a hair dryer can be used in a variety of ways. The second hair dryer disclosed herein aims to provide a hair dryer that can be used in a new way.

[0090] (Implementation 13) Figure 47 This is a front view of the structure of a hair dryer 300 according to Embodiment 13. The hair dryer 300 is designed to be self-standing. Specifically, the hair dryer 300 can be self-standing when in use (when blowing air). This reduces the burden on the user of the hair dryer 300 when drying hair. For example, even if the air temperature is lowered to dry hair more slowly, the user is less likely to feel fatigued.

[0091] Specifically, the hair dryer 300 includes a hair dryer body 310. The hair dryer body 310 is provided with an air inlet 20, a first air outlet 52, and a second air outlet 57. When installed (freestanding), the hair dryer body 310 is elongated, with its major axis extending along the z-axis (vertical direction). The hair dryer body 310 includes a grounding surface 310a. The grounding surface 310a is located on one side (the lower side) of the hair dryer body 310 in the longitudinal direction (z-axis direction). This grounding surface 310a enables the hair dryer 300 to be freestanding. In this embodiment, the grounding surface 310a is described as being a flat surface. However, the grounding surface is not limited to a flat surface and may, for example, be a surface having an upwardly concave portion.

[0092] In the hair dryer 300, at least one of the air intake port 20, the first air outlet 52, and the second air outlet 57, specifically both, opens toward the z1 side (upper side) in the longitudinal direction, i.e., the z-axis. In this embodiment, after the attachments (the first air outlet 31 and the second air outlet 36) are installed, the outgoing air is blown in a direction perpendicular to the z-axis (e.g., the y-axis), while the intake air is drawn into the hair dryer 300 from the z1 side in the z-axis and flows toward the z2 side. Therefore, compared to a case where both the intake and exhaust air flow in directions different from the normal to the ground plane, the hair dryer 300 maintains a more stable free-standing position. In other words, the hair dryer 300 can be stably free-standing. Therefore, even when the intake or exhaust air volume of the hair dryer 300 is large, or the wind speed is high, the free-standing position is easily maintained.

[0093] In the hair dryer 300, the air inlet 20, the first air outlet 52, and the second air outlet 57 are all located on the z1 side (upper side) in the longitudinal direction of the hair dryer body 310. Therefore, the blown air and the inlet air are less likely to affect the ground surface on which the ground surface 310a is provided, further stabilizing the free-standing posture of the hair dryer 300.

[0094] The hair dryer body 310 includes a base 311 and a platform 315. The platform 315 is a portion including the grounding surface 310a. The platform 315 is located on the z2 side of the base 311 in the z-axis direction. The platform 315 is connected to the base 311. In this embodiment, an example is provided in which the base 311 and the platform 315 are separately provided and connected to each other. However, the base 311 and the platform 315 may also be provided as an integral part. In other words, the base 311 and the platform 315 may be formed from a single component.

[0095] Figure 48 3 is a schematic rear view of the hair dryer 300. Figure 48As shown, when viewed in the z-axis direction, the grounding surface 310a includes a portion located outside the area of ​​the base 311's end portion on the platform 315 side. Therefore, the hair dryer 300 is more stable in its free-standing position than if the grounding surface 310a and the end portion on the platform 315 side of the base 311 had identical planar shapes. From the same perspective, the area of ​​the grounding surface 310a, when viewed in the z-axis direction, is preferably larger than the projected area of ​​the end portion on the platform 315 side of the base 311 as viewed in the z-axis direction.

[0096] In the hair dryer 300, the base 311 and the grounding surface 310a each have an elongated shape when viewed from the z-axis direction. When viewed from the z-axis direction, the base 311 and the grounding surface 310a are substantially similar in shape, and their centroids are located at the same position.

[0097] The platform 315 is rotatable relative to the base 311 about a central axis AX3, which passes through the center of the ground contact surface 310a and extends along the z-axis. For example, when the user is hand-holding the hair dryer 300, the platform 315 is positioned relative to the base 311 so that the length of the base 311 (hereinafter sometimes referred to as the "length of the base 311 in plan view") is substantially aligned with the length of the ground contact surface 310a when viewed from the z-axis. This reduces the platform 315's obstruction and improves the user-friendliness of the hair dryer 300. On the other hand, when the hair dryer 300 is used in a free-standing position, it is preferable to rotate the platform 315 relative to the base 311 so that the length of the ground contact surface 310a is aligned with the direction of air blown from the hair dryer 300. In this way, the reaction force generated by the blown air can be appropriately applied to the hair dryer 300 from the ground contact surface 310a, further stabilizing the self-standing posture. From this point of view, the table 315 is preferably rotatable relative to the base 311, and the table 315 is elongated. When the hair dryer 300 is designed to blow air in a direction perpendicular to the length direction (z-axis direction) of the hair dryer body 310, this structure is more effective. When the multiple air outlets 32, 37 of the hair dryer 300 can blow air in the same direction perpendicular to the z-axis direction, the effect of this structure is more significant. Specifically, in the hair dryer 300, if Figure 47 As shown, each of the plurality of air outlets 32, 37 can blow air in the same y-axis direction perpendicular to the z-axis direction. When the hair dryer 300 is used in a self-standing position, the position of the table 315 is preferably adjusted so that the length direction of the grounding surface 310a is along the y-axis direction.

[0098] It is preferable that the static friction coefficient of at least a portion of the contact surface 310a, substantially all of the contact surface, is greater than the static friction coefficient of at least a portion of the surface of the hair dryer body 310 (for example, at least a portion of the outer peripheral surface of the base 311). In this case, when the air blown from the hair dryer 300 exerts a horizontal force on the hair dryer 300, the friction between the contact surface 310a and the contacted surface can generate a greater reaction force. This further stabilizes the free-standing posture of the hair dryer 300. Specifically, for example, it is also preferable to select the materials of the base 311 and the base 315 so that the static friction coefficient of a sample surface (first surface) made of the material constituting the base 311 is greater than the static friction coefficient of a sample surface (second surface, having the same arithmetic mean roughness (Ra) as the first surface) made of the material constituting the base 311.

[0099] To further stabilize the self-standing posture of the hair dryer, for example, at least a portion of the grounding surface 310a is preferably sticky, and the grounding surface 310a also preferably has an adsorption portion that can be adsorbed onto a grounded surface in contact therewith.

[0100] (Variation 1 of Implementation 13) Figure 49 This is a rear view of a hair dryer according to Modification 1 of Embodiment 13. Figure 49 The hair dryer of Modification 1 shown here differs from the hair dryer in the shape of the platform 315 and the grounding surface 310a, but the rest of the structure is substantially the same as the hair dryer. Therefore, the description here will focus on the shape of the grounding surface 310a, and the remaining description will refer to the content of Embodiment 13.

[0101] In this first modification, the platform 315 is designed so that the centroid of the end portion of the base 311 on the platform 315 side and the centroid of the ground contact surface 310 a are located at different positions when viewed from the z-axis direction.

[0102] In this modification 1, when viewed from the z-axis direction, the centroid of the ground contact surface 310a is located on the y2 side, which is the opposite side to the y1 side, in the vertical direction (e.g., the y-axis direction), relative to the center of gravity of the base 311, where the wind blows out in the y-axis direction. Specifically, Figure 49 As shown, by rotating the table 315, the table 315 can be rotated relative to the base 311 so that, when viewed from the z-axis direction, the centroid G of the ground contact surface 310a is located closer to the y2 side than the center of gravity of the base 311. This further stabilizes the free-standing posture of the hair dryer even when the air blown out from the hair dryer is blown along the y1 side.

[0103] (Variation 2 of Implementation 13) Figure 50 This is a rear view of a hair dryer according to Modification 2 of Embodiment 13. The hair dryer of Modification 2 differs from the hair dryer 300 of Embodiment 13 in that the table 315 is non-rotatable relative to the base 311 and the shape of the grounding surface 310a is different. The remaining structures are essentially the same. Therefore, this description focuses primarily on the shape of the grounding surface 310a, with the remainder referring to Embodiment 13.

[0104] When viewed along the length of the hair dryer body 310, i.e., the z-axis, the platform 315 is designed so that the centroid G of the grounding surface 310a is located on the y2 side of the base 311 in the vertical direction (e.g., the y-axis). The grounding surface 310a is bulging toward the y2 side. Therefore, the force exerted by the grounding surface on the grounding surface 310a further stabilizes the free-standing position of the hair dryer. When viewed along the z-axis, the largest portion of the grounding surface 310a in the y-axis is preferably located approximately at the same position as the center of gravity of the base 311 in the x-axis.

[0105] (Implementation 14) Figure 51 This is a side view of the hair dryer 400 according to the fourteenth embodiment in a state where the sliding member 410 is housed. Figure 52 This is a side view of the hair dryer 400 according to the fourteenth embodiment in a state where the sliding member 410 is extended.

[0106] like Figure 51 and Figure 52 As shown, in this embodiment, the base and the table are integrally formed. The grounding surface 310a is composed of the housing 10 and the sliding member 410 described in detail below. Here, the sliding member 410 is mainly described in detail, and the remaining contents are referenced from the above description.

[0107] The sliding member 410 is installed to be slidable along the y-axis direction relative to the housing 10. Figure 51 As shown, when the sliding member 410 is displaced toward the y1 side (front side), it is housed within the housing 10. In this embodiment, the sliding member 410 is described as being substantially entirely housed within the housing 10. However, the present invention is not limited to this configuration. The sliding member 410 may also be housed within the housing 10 while partially protruding from the housing 10.

[0108] like Figure 52 As shown, the sliding member 410 can be Figure 51 The storage position shown and Figure 52Therefore, in this embodiment, at least a portion of the table portion can slide relative to the base portion in a direction perpendicular to the length direction of the hair dryer body (housing 10). At least a portion of the slidable table portion constituting the sliding member 410 can be in a first state (storage state, see FIG. 1 ) located in the area where the base portion is located when viewed from the length direction of the hair dryer body. Figure 51 ) and a second state (extended state, referring to Figure 52 ) between the two options.

[0109] When the sliding member 410 is in the retracted state, it is possible to prevent the sliding member 410 from protruding from the housing 10, thereby preventing the sliding member 410 from interfering with the user's use. When the sliding member 410 is in the extended state, the sliding member 410 can expand the area where the contact surface 310a is located, thereby stabilizing the self-standing posture of the hair dryer 400.

[0110] In this embodiment, the sliding member 410 is described as a flat plate. However, the sliding member may have a shape that becomes wider or higher toward the extended state.

[0111] (Implementation 15) Figure 53 It is a side view of the hair dryer of Embodiment 15. The hair dryer of this embodiment is a hair dryer of embodiment 1 with the attachment replaced by Figure 53 The product is shown with the accessory 510. The accessory 510 includes an air guide 511 and a support 512 that are substantially identical to the accessory described in Embodiment 1. The support 512 is connected to the air guide 511. The support 512 includes a portion extending from the support 512 toward the z2 side (lower side) in the z-axis direction. In the support 512, a portion of the housing 10 forms a portion of the grounding surface 310a in the z-axis direction. The portion of the grounding surface 310a formed by the housing 10 is located at substantially the same position in the z-direction as the z2-side front end of the support 512. Therefore, the z2-side end surface of the support 512 also forms a portion of the grounding surface 310a. This arrangement expands the area where the grounding surface 310a is provided, resulting in a more stable self-standing position of the hair dryer.

[0112] When the user uses the hair dryer by hand, the user can improve the user experience when using the hair dryer by hand by replacing the accessory 510 with the accessories described in the first embodiment.

[0113] (Implementation 16) Figure 54 This is a side view of the hair dryer according to the sixteenth embodiment in a state where the stand is closed. Figure 55This is a side view of the hair dryer according to the sixteenth embodiment with its stand opened. Figure 56 It is a side view of the hair dryer according to the modification of the sixteenth embodiment in a state where the holder is closed. Figure 57 It is a side view of the hair dryer according to the modification of the sixteenth embodiment in a state where the stand is opened.

[0114] like Figures 54-57 As shown, for example, brackets 600, 610 can be mounted on the hair dryer body 310. Figure 55 、 Figure 57 As shown, the brackets 600 and 610 are designed so that the front ends of the brackets 600 and 610 are in a grounding posture that can be away from the hair dryer body 310 and can be grounded. When the brackets 600 and 610 are set to the grounding posture, the self-standing posture of the hair dryer can be stabilized.

[0115] The brackets 600 and 610 are preferably rotatably mounted at their base ends on the hair dryer body 310 so that the brackets 600 and 610 can be changed between a posture stored in or in contact with the hair dryer body 310 and a grounded posture.

[0116] exist Figure 54 and Figure 55 In the embodiment 16 shown, as Figure 55 As shown, in the grounded posture, the grounding surface 310a of the housing 10 is grounded, the hair dryer body is vertically arranged and extends along the z-axis direction, and the front end of the bracket 600 is also grounded.

[0117] exist Figure 56 and Figure 57 In the modified example of embodiment 16 shown in FIG. Figure 57 As shown, in the grounded posture, the hair dryer body extends in a direction inclined with respect to the z-axis direction, and maintains a posture in which the air blown from the hair dryer is blown obliquely upward.

[0118] Hereinafter, other examples of the third and fourth hair dryers of the present disclosure will be described. In the following description, for components using the same terms as those in the above embodiment, the description in the above embodiment can be cited. The third and fourth hair dryers of the present disclosure are intended to provide a hair dryer that is excellent in both quietness and impact resistance.

[0119] (Implementation 17) Figures 58-63 : is a diagram showing the structure of a hair dryer according to Embodiment 17. Figure 58 It's a stereogram. Figure 59 It is a side view. Figure 60 is the main view, Figure 61 It is a top view. Figure 62 This is a cross-sectional view from the side. Figure 63 For the sake of convenience, the direction of the hair dryer of embodiment 17 will be viewed from the front when the blow-out port is viewed ( Figure 60 The side shown in FIG1 is called the "front side" and the side ( FIG1 is a side view of the handle 15) when observing the length direction of the hair dryer body. Figure 59 The side shown in FIG1 is called the "side face" and the side (shown in FIG10) when observing the length direction of the hair dryer body from the opposite side of the bottom of the handle 15 is called the "side face". Figure 60 The side shown in FIG. 1 is referred to as the “top side”.

[0120] The hair dryer of embodiment 17 is a so-called gun-type hair dryer, comprising a hair dryer body and a handle 15 connected thereto, forming a T-shape when viewed from the side. The hair dryer body includes two air cylinders 51 and 56. Air cylinders 51 and 56 are cylindrical components, each having an air intake 121 or 122 at one end and a first air outlet 52 or a second air outlet 57 at the other end.

[0121] An electric blower (first electric blower) 61 and a heater 71 are provided inside the air cylinder 51. An electric blower (second electric blower) 62 and a heater 72 are provided inside the air cylinder 56. From the viewpoint of operability, when there are two gas cylinders, the handle 15 is preferably disposed between the two gas cylinders.

[0122] The outside of the air cylinder 51 forming the first ventilation path and the air cylinder 56 forming the second ventilation path, the side surface, the top surface, the bottom surface (the surface on the side of the handle 15), etc. are covered with the sound-absorbing material 26 all around. In this embodiment, since the air cylinders 51 and 56 are not housed in the shell, the sound-absorbing material 26 is exposed on the outside of the air cylinder (first shell) 51. When the sound-absorbing material 26 is exposed to the outside, the impact resistance can be improved by the sound-absorbing material 26. There is no particular restriction on the type of sound-absorbing material 26, but from the viewpoint of improving impact resistance, it is preferably composed of a soft material, for example, a sheet material composed of a plurality of fibers, a woven fabric or a non-woven fabric, or a resin porous body (sponge), etc. are more suitable.

[0123] Furthermore, the air cylinder 51 as the first shell and the air cylinder 56 as the second shell may be in close contact with each other or may be separated from each other, and the sound absorbing material 26 may be arranged between them.

[0124] The hair dryer of embodiment 17 may further include an outer wall member that covers part or all of the periphery of the sound-absorbing material 26. The inclusion of an outer wall member enhances strength. If the outer wall member has an opening, the portion of the sound-absorbing material 26 exposed further outward from the outer wall member serves as the grounding surface of the hair dryer body, thereby improving impact resistance. To ensure waterproofing, the periphery of the sound-absorbing material 26 of the hair dryer of embodiment 2 may be covered with a non-water-absorbent member. By attaching a non-water-absorbent member to the portion of the sound-absorbing material 26 exposed at the opening of the outer wall member containing the sound-absorbing material 26, impact resistance can be improved while ensuring waterproofing.

[0125] The blow-out attachment (blow-out component) 160 can be installed on the first blow-out port 52 and the second blow-out port 57 of the air cylinder 51, 56. The sound-absorbing material 26 can be arranged not only in the air path in the hair dryer body, but also in the air path (blow-out ventilation path) in the blow-out component. The sound-absorbing material 26 can be arranged on the inner side of the blow-out component so that it is exposed in the blow-out ventilation path, or it can be arranged on the outer side of the blow-out component. Figure 63 In the embodiment, the sound-absorbing material 26 is cylindrically mounted on the inner circumference of the blowout attachment 160. The sound-absorbing material 26 can be adhered to the inner circumference with an adhesive, or it can be secured by clamping it between another cylindrical component and the inner circumference. It should be noted that the blowout attachment 160 can be configured to be detachably connected to each other in the longitudinal direction. This allows the length of the blowout attachment 160 to be adjusted, either longer or shorter.

[0126] In addition, an air suction attachment (air suction component) 150 can be installed on the air suction ports 121 and 122 of the air cylinders 51 and 56. The sound absorbing material 26 can be arranged not only in the air path within the hair dryer body, but also in the air path (air suction ventilation path) within the air suction component. The sound absorbing material 26 can be arranged on the inner side of the air suction component so that it is exposed in the air suction ventilation path, or it can be arranged on the outer side of the air suction component. Figure 63 In the embodiment, the sound-absorbing material 26 is cylindrically mounted on the inner circumference of the air suction attachment 150. The sound-absorbing material 26 can be adhered to the inner circumference with an adhesive, or it can be clamped and secured between other cylindrical components and the inner circumference. It should be noted that the air suction attachment 150 can be configured to be detachably connected to each other in the longitudinal direction. This allows the length of the air suction attachment 150 to be adjusted, either longer or shorter.

[0127] (Implementation 18) Figure 64 This is a perspective view of the structure of a hair dryer according to Embodiment 18. The hair dryer according to Embodiment 18 is the same as the hair dryer according to Embodiment 17, except that it is a single-cylinder type. A sound absorbing material 26 is disposed around the cylinder 51 and is exposed to the outside.

[0128] (Implementation 19) Figures 65-68 19 is a diagram showing the structure of a hair dryer according to the embodiment 19. Figure 65 is the main view, Figure 66 It is a top view. Figure 67 This is a cross-sectional view from the front. Figure 68 The hair dryer of the nineteenth embodiment differs from the hair dryer of the first embodiment in two points: the structure of the blow-out attachment and the provision of a cover member covering the blow-out port.

[0129] In this embodiment, the sound absorbing material 26 is disposed not only in the air passage within the hair dryer body but also in the air passage (blow-out ventilation passage) within the blow-out attachment (blow-out member). The sound absorbing material 26 is disposed inside the blow-out member and exposed within the blow-out ventilation passage. The sound absorbing material 26 may also be disposed outside the blow-out member. In the hair dryer body, the sound-absorbing material 26 can be arranged in the first air passage 21, the return portion 22, the second air passage 23, or, as shown in the figure, in both the first air passage 21 and the second air passage 23. The blower attachment is a curved cylindrical component, including a first cylindrical body 231 having a first air intake and a first blowout 232, and a second cylindrical body 236 having a second air intake and a second blowout 237. The sound-absorbing material 26 is disposed inside the first cylindrical body 231 and the second cylindrical body 236.

[0130] The air intake and air outlet of the blower attachment open in different directions. The direction of air blowing out of the main blower outlets 252 and 257 is parallel to the length of the hair dryer body. However, after passing through the crank-shaped curved air path formed by the blower attachment, the direction of air blowing out of the hair dryer's outlet is perpendicular to the length of the hair dryer body and is blown toward the front of the hair dryer body. By forming the hair dryer's outlet with the blower attachment, the opening direction and shape of the outlet can be selected according to the usage of the hair dryer 4, thereby improving the user-friendliness of the hair dryer 4. The curved shape of the blower attachment provides a certain length in the blowing direction, thus providing good airflow regulation.

[0131] The first barrel 231 is a cylindrical component with a hollow interior. It draws air from a first air intake port connected to the main blower outlet 252 of the hair dryer body and blows the air outward from the first blower outlet 232. The second barrel 236 is a cylindrical component with a hollow interior. It draws air from a second air intake port connected to the main blower outlet 257 of the hair dryer body and blows the air outward from the second blower outlet 237. In this embodiment, the first barrel 231 and the second barrel 236 are separate components that can be replaced separately. However, the blower attachment may also be a component that combines the first barrel 231 and the second barrel 236.

[0132] There is no particular limitation on the shape of the first outlet 232 and the second outlet 237 of the blower attachment, and they may be, for example, circular, elliptical, oblong, polygonal, etc. Furthermore, there is no particular limitation on the size of the first outlet 232 and the second outlet 237 of the blower attachment, and they may be the same size as the first air inlet and the second air inlet, or smaller than the first air inlet and the second air inlet, or larger than the first air inlet and the second air inlet.

[0133] From the perspective of wind rectification, the front ends of the first cylinder 231 and the second cylinder 236, namely the first blowing outlet 232 and the second blowing outlet 237, should be as long as possible in the front direction. They can protrude from the front of the hair dryer body, but from the perspective of storage, they preferably do not protrude from the front of the hair dryer body.

[0134] It should be noted that the blow-out accessories can be Figure 65 The axes (central axes of the air passages) AX3 and AX4 (in the plan view) shown in FIG. Figure 65 The rotatable blower attachment can be locked and rotated at any angle. The rotatable angle is not particularly limited, for example, 0-360 degrees.

[0135] Alternatively, the detachable blow-out attachment may not be provided. Figure 65 The first barrel 231 and the second barrel 236 of the shape shown are integrally formed with the hair dryer body.

[0136] The first and second barrels 231, 236 of the blower attachment each can be fitted with a cover member 234 to cover the blowout outlet. The cover member 234 allows the shape and size of the blowout outlet of the hair dryer 4 to be adjusted based on the intended use of the hair dryer 4, thereby enhancing the user experience of the hair dryer. The cover member 234 can be a separate component detachable from the first and second barrels 231, 236, or it can be integrally integrated with the first and second barrels 231, 236. Furthermore, the cover member 234 can rotate about the center point of the first and second blowout outlets 232, 237. Rotating the cover member 234 allows the distance between the two blowout outlets of the hair dryer 4 to be adjusted, allowing for different drying methods. When the two blowout outlets of the hair dryer 4 are close together, the two airflows can be combined, delivering a stronger airflow within a smaller area. Conversely, when the two blowout outlets of the hair dryer are farther apart, airflow can be delivered over a wider area. In particular, when different air volume controls are performed on a plurality of air cylinders, it is preferable to increase the distance between the two air outlets of the hair dryer in order to utilize two air flows separately.

[0137] (Implementation 20) In embodiment 1, the air intake port 20 is arranged along the outer periphery of the shell 10 on the top of the hair dryer body, and the blow-out ports (the first blow-out port 52 and the second blow-out port 57) are arranged on the inner side, while in this embodiment, the air intake port 20 is arranged on one side on the top of the hair dryer body, and the blow-out ports (the first blow-out port 52 and the second blow-out port 57) are separately arranged on the other side.

[0138] The air intake 20 on the upper side of the hair dryer body is arranged on one side, so that the width of the air intake 20 and the first air path portion 21 adjacent to the side of the shell 10 is increased. In this way, the air intake volume on one side of the shell 10 is increased, so when the control substrate 80 is arranged on the side of the first air path portion 21, a higher cooling efficiency can be obtained. In addition, since the first air path portion 21 is not provided on the other side of the shell 10, an opening can be provided on the shell 10, and the sound-absorbing material 26 can be exposed to the outside of the shell 10 from the opening. Using the exposed portion of the sound-absorbing material 26 as the grounding surface (placement bottom surface) of the hair dryer body can improve impact resistance. In addition, by installing a non-water-absorbing component on the exposed portion of the sound-absorbing material 26, it is possible to ensure waterproofness while improving impact resistance.

[0139] When the upper air intake 20 of the hair dryer body is located on the front side and the first and second air outlets 52, 57 are located on the back side, for example, by using the curved first cylindrical body 231 of Embodiment 19, the first and second cylindrical bodies 231 can be prevented from protruding from the front of the housing 10, thereby improving the storage of the hair dryer. On the other hand, when the upper air intake 20 of the hair dryer body is located on the back side and the first and second air outlets 52, 57 are separated and located on the front side, the distance between the air intake 20 and the first and second air outlets 52, 57 can be increased, thereby preventing the air flow from being affected by a short circuit between the air intake and the air discharge in the hair dryer.

[0140] Hereinafter, another example of the fifth hair dryer of the present disclosure will be described. In the following description, for components using the same terms as those in the above embodiment, the description in the above embodiment can be cited. The fifth hair dryer disclosed herein aims to provide a hair dryer that can be used in a variety of ways.

[0141] Regarding the fifth hair dryer, "flow direction" and "flow path direction" respectively refer to the direction of the flow along an imaginary line connecting the centers of the flow path. The center of the flow path refers to the center of the cross-sectional shape of the flow path. "Flow direction" and "flow path direction" can be directions extending along a straight line. For example, if the flow path has a bend or curve, they can also be directions partially or entirely along an imaginary line extending along the bend or curve. In this case, "flow direction" and "flow path direction" can each be composed of different vectors at different positions along an imaginary line connecting the centers of the flow path (this imaginary line is also referred to as the "flow path centerline").

[0142] Regarding the fifth hair dryer, two lines or two planes being "parallel" means that the angle (absolute value) between them is within the range of 0°±3°. Two lines or two planes being "perpendicular" means that the angle (absolute value) between them is within the range of 90°±3°.

[0143] Regarding the fifth hair dryer, the first direction D1 is called the x-axis direction, the second direction D2 perpendicular to the first direction D1 is called the y-axis direction, and the third direction D3 perpendicular to the xy plane formed by the x-axis and the y-axis is called the z-axis direction.

[0144] (Implementation 21) Figure 69 This is a side view schematically showing a first aspect of the hair dryer according to the twenty-first embodiment. Figure 70 2 is a side view schematically showing a second embodiment of the hair dryer of embodiment 21. Figure 69 and Figure 70 As shown, a hair dryer 601 according to embodiment 21 includes a main body 604 and a grip 605 attachable to the main body 604. The main body 604 includes a blower 602 and a cylinder 603. The cylinder 603 extends in a first direction. The blower 602 is disposed at one end of the cylinder 603. The first direction D1 is the direction in which the cylinder 603 extends, i.e., the longitudinal direction of the cylinder 603. The blower 602 can be integral with the main body 604, making it non-removable, or it can be designed to be attachable to and detachable from the main body 604. If the blower 602 is detachable from the main body 604, the cylinder 603 can extend relative to the blower 602 in the first direction when the blower 602 is attached to the main body 604. The specific structure of the main body will be described later.

[0145] The grip portion 605 is a portion for the user to hold when using the hair dryer 601. The grip portion 605 can be mounted on the main body 604 in two ways: the first way is to extend along the first direction (see Figure 69 ), the second method is to extend the installation in a direction inclined to the first direction (refer to Figure 70Since the grip portion 605 can be mounted on the main body 604 in the first and second modes, the hair dryer of embodiment 21 can be used in a variety of ways.

[0146] In the first embodiment, the gripping portion 605 is mounted on the main body 604 and extends in the first direction. The angle formed by the extension direction of the cylinder portion 603 (the first direction) and the extension direction of the gripping portion 605 is set to θ1. In the first embodiment, the gripping portion 605 can be mounted parallel to the first direction or mounted on the main body 604 at an angle θ1 of more than 0° and less than 30°. Figure 70 θ1 is the angle when viewing a plane formed by the extension direction of the cylinder portion 603 (the first direction) and the extension direction of the grip portion 605 from a vertical direction. With the first direction being 0°, the angle θ1 increases as the other end of the grip portion 605 mounted on the main body 604 tilts toward the blowout portion 602. It should be noted that in the first embodiment, the grip portion 605 can be mounted on the main body 604 with the point at which it is mounted on the main body 604 as the vertex and the first direction as the axis of rotation, with the cone half-apex angle being within a range greater than 0° and less than or equal to 30°.

[0147] At least a portion of the grip portion 605 may include a straight portion. In this case, the straight portion only needs to extend in the first direction. Furthermore, the grip portion 605 may include other straight portions or curved portions that form a different angle with the first direction than the straight portion. In this case, it is preferred that the longest straight portion extend in the first direction.

[0148] In the first embodiment, the hair dryer 601 has an overall I-shaped appearance. Figure 71 This is a front view of the hair dryer 601 viewed from the blow-out portion side along the first direction. Figure 71 As shown, in the first embodiment, when the hair dryer 601 is viewed from the first direction, at least a portion of the grip 605 preferably overlaps with the main body 604. In the first embodiment, when viewed from above or below (z-axis direction), for example, the cylinder 603 and the grip 605 are preferably aligned in the first direction relative to the blower 602.

[0149] In the second embodiment, the grip portion 605 is mounted on the main body 604, extending in a direction oblique to the first direction. In the second embodiment, the angle θ1 formed between the extension direction of the cylinder portion 603 (the first direction) and the extension direction of the grip portion 605 is preferably greater than θ1 in the first embodiment, and θ1 is less than or equal to 180°. Conventional hair dryers often adjust the grip portion angle within a range of θ1 between 90° and 180°. However, the hair dryer 601 of Embodiment 21 allows adjustment of the grip portion angle not only within a range of θ1 between 90° and 180°, but also within a range of less than 90°, thus accommodating a wider range of usage options.

[0150] exist Figure 70 In the description, the example of the grip portion 605 tilting in the first direction within the xz plane defined by the first direction (x-axis) and the z-axis perpendicular to the first direction is used. However, the tilting direction of the grip portion 605 is not limited to the xz plane; the grip portion 605 can be tilted in any direction intersecting the first direction. In other words, θ1 can be the semi-apex angle of a cone whose apex is the point where the grip portion 605 is attached to the main body 604 and whose rotation axis is the first direction.

[0151] In embodiment 21, the grip portion 605 and the main body portion 604 are preferably connected in a rotatable but non-detachable manner. Figure 72 1 is a side view schematically showing a first embodiment of a hair dryer in which the main body has a rotating member. Figure 72 As shown, the main body 604 further includes a rotating member 604a for rotating the grip 605 relative to the main body 604 between a first mode and a second mode. By including the rotating member 604a, the hair dryer 601 of Embodiment 21 can change the angle of the grip 605 relative to the main body 604 between the first mode and the second mode.

[0152] The rotating member 604a is preferably disposed in the portion of the main body 604 opposite the blowout portion 602. Since the grip portion 605 is connected to the main body 604 via the rotating member 604a, the grip portion 605 is also preferably disposed in the portion of the main body 604 opposite the blowout portion 602. The rotating member 604a or grip portion 605 being disposed in the portion of the main body 604 opposite the blowout portion 602 means that the rotating member 604a or grip portion 605 is disposed at a position farther from the blowout portion 602 than the midpoint of the main body 604 in the longitudinal direction. The rotating member 604a or grip portion 605 may be disposed on the end surface of the main body 604 opposite the blowout portion 602 (the side of the main body 604 farthest from the blowout portion 602) or on the side closer to the blowout portion 602 than this end surface (the end of the main body 604 opposite the blowout portion 602). The rotating member 604a or grip 605 is located at the end of the main body 604 opposite the blow-out portion 602. This means that the rotating member 604a or grip 605 is located within a range from, for example, a position 1 / 10 of the length of the main body 604 to the end face. It should be noted that, from the perspective of reducing the burden on the user, even if the grip 605 is located closer to the blow-out portion 602 than the end face, it is preferably installed near the center of gravity of the hair dryer 601.

[0153] Figure 73 1 is a side view schematically showing another example of the first embodiment of the hair dryer in which the main body has a rotating member. Figure 73 As shown, when the end face of the main body 604 on the side opposite to the blowing portion 602 is arranged closer to the blowing portion 602, the length L1 from the end of the side of the holding portion 605 mounted on the main body 604 (cylinder portion 603) to the end of the side opposite to the side of the holding portion 605 mounted on the main body 604 is preferably greater than the length L2 from the position where the holding portion 605 is mounted on the main body 604 to the end face of the main body 604 on the side opposite to the blowing portion 602. With such a structure, in the first mode, the user can hold the holding portion 605 more stably. The difference L3 between L1 and L2 mentioned above can be any length that the user can hold the holding portion, for example, preferably more than 5 cm. The upper limit of L3 is not particularly limited, for example, it is preferably less than 30 cm.

[0154] Figures 74A-74C It is a schematic representation Figure 72 The side view of the second embodiment of the hair dryer 601 is shown. Figures 74A-74C In FIG. 1 , the position of the holding portion 605 in the first embodiment is indicated by a two-dot chain line. The holding portion 605 can be as follows: Figure 74AAs shown, it is mounted on the main body 604 at an angle θ1 greater than 0° and less than or equal to 90°, or it can be mounted as shown. Figure 74B As shown, by increasing θ1 to greater than 90°, you can also Figure 74C Fold as shown. Figure 74C When the grip 605 is folded, θ1 is 180°. The rotating member 604a is preferably capable of maintaining the grip 605 at any angle between 0° and 180°. With this structure, the user can dry their hair while maintaining the grip 605 at a preferred angle.

[0155] The rotating component 604a is not particularly limited as long as it can change the angle of the grip portion relative to the main body 604. For example, a hinge, a universal joint, a ball joint, etc. can be listed. The above-mentioned hinge is a one-degree-of-freedom rotating component that can adjust the angle around an axis extending in any direction. The above-mentioned universal joint is a two-degree-of-freedom rotating component that can adjust the angle around an axis extending in any direction and an axis extending in a direction different from the axis extending in any direction. For example, it has a structure with multiple hinges. The above-mentioned ball joint is, for example, a three-degree-of-freedom rotating component that can rotate in any direction. For example, it has a structure with a ball and a ball seat that wraps the ball to prevent the sphere (ball) from falling off.

[0156] Figure 75 This is a cross-sectional view schematically illustrating the internal structure of the main body of a hair dryer 601 according to Embodiment 21. The interior of the blower unit 602 is a space having an opening, or blow-out port (not shown), for blowing air to the outside. The interior of the blower unit 602 serves as a flow path for air drawn in through an air inlet 603b of the cylinder unit 603, described later, to flow to the blow-out port.

[0157] The blowing portion 602 is preferably rotatably mounted on the cylinder portion 603. In the present embodiment, the blowing portion 602 is rotatably mounted on the cylinder portion 603 with the first direction (x-axis direction) serving as the rotation axis. It should be noted that the blowing portion 602 may also be movably mounted on the cylinder portion 603 in the y-axis direction (left-right direction), or movably mounted on the cylinder portion 603 in the z-axis direction (up-down direction), or rotatably mounted on the cylinder portion 603 in the first direction (x-axis direction) serving as the rotation axis 360°. Furthermore, the blowing portion 602 may be rotated manually or automatically by electric means.

[0158] The blowout port can be provided on the end face (also referred to as the end wall) on the side opposite to the cylinder portion 603 of the blowout portion 602, or on the side wall of the end. The shape of the blowout port is not particularly limited. The blowout port can be circular or elongated. The elongated shape of the blowout port means that, when viewed from the front of the blowout port, the longest length passing through the centroid of the blowout port is greater than the shortest length of the blowout port. Therefore, the longest length passing through the centroid of the blowout port is set to La, and the shortest length of the blowout port is set to Sa. The elongated shape of the blowout port means that the blowout port satisfies La>Sa. In addition, the aspect ratio (La / Sa) obtained by dividing the longest length La passing through the centroid of the blowout port by the shortest length Sa of the blowout port is preferably greater than 3 and less than 20. That is, the above-mentioned aspect ratio of the blowout port is preferably greater than 3 and less than 20. The above-mentioned aspect ratio is more preferably greater than 5, and further preferably greater than 6.

[0159] The blow-out portion 602 may have a blow-out fin 602a (also called a wind direction changing plate) near the blow-out outlet. The blow-out fin 602a is an air-guiding component used to control the direction of air flow or to rectify the air flow. In the blow-out outlet having the blow-out fin 602a, a plurality of blow-out fins 602a may be arranged. The blow-out fin 602a may be fixed to the blow-out outlet, or the angle of the air suction fin may be manually changed by the user, or the angle may be automatically changed electrically. By controlling the flow of wind through the blow-out fin 602a, the hair dryer 601 may, for example, make the flow direction (referred to as wind direction) of the wind blown out from the blow-out outlet having the blow-out fin 602a blow toward the front of the main body 604, or may make it blow toward the rear of the main body 604.

[0160] like Figure 75 As shown, the air cylinder portion 603, for example, has an air intake 603b, an electric blower 603c and a heater 603d. The air cylinder portion 603 is preferably a cylindrical component with a space inside. The cross section of the air cylinder portion 603 can be any shape such as circular, elliptical, oblong, polygonal, etc. The air cylinder portion 603 as a whole preferably has an I-shaped appearance. On the end face of the air cylinder portion 603 on the side opposite to the configuration blow-out portion 602, an opening (i.e., air intake 603b) for inhaling air from the outside is preferably formed. The internal space of the air cylinder portion 603 is the flow path of the inhaled air flowing to the blow-out portion 602. The air inhaled by the air cylinder portion 603 flows inside the air cylinder portion 603 and is then blown to the outside from the blow-out port of the blow-out portion 602.

[0161] The air intake 603b is a component that draws in air from the outside, and the electric blower 603c is a component that blows air from the air intake 603b to the blower 602. The air cylinder 603 includes a control substrate (not shown). The control substrate is a substrate that carries a control unit that controls the operation of the hair dryer 601. The control unit may include, for example, a chip-shaped control component and a substrate on which the control component is mounted. The control unit controls, for example, the electric blower 603c, the heater 603d, and the like. If the hair dryer 601 has movable blower fins or movable air intake fins, the control unit can also control these components. By placing the control substrate between the air intake 603b and the blower 602, the control substrate can be cooled by the air flowing within the air cylinder 603.

[0162] Suction fins (not shown) may be provided near the air intake 603b. Suction fins are wind-guiding components used to control or rectify the air flow. Suction fins may be provided in the air intake 603b having suction fins. The suction fins may be fixed to the air intake 603b, the angle of which may be manually adjusted by the user, or automatically adjusted electrically.

[0163] The electric blower 603c is preferably located upstream of the cylinder 603, and the heater 603d is preferably located downstream. The terms "upstream" and "downstream" refer to the upstream and downstream sides of the air flow direction, respectively. The upstream side is the air intake side, and the downstream side is the air outlet side.

[0164] An electric blower is a general term for a mechanism that uses electricity to supply air. For example, an electric blower can be a mechanism that supplies air by rotating a component that forms an airflow (such as a fan) using electricity, or a mechanism that generates airflow by generating vibrations or the like using electricity to form high-pressure and low-pressure areas. For example, an electric blower preferably includes a fan and a motor that drives the fan. There is no particular limitation on the arrangement of the fan and the motor in the direction of flow. For example, the fan can be arranged on the upstream side and the motor on the downstream side.

[0165] As the motor, for example, a brushless motor, an induction motor, a synchronous reluctance motor, etc. are commonly used. Among them, a brushless motor is more preferred, and a brushless DC motor is even more preferred.

[0166] Because brushless motors lack brushes that contact the rotor, they can suppress the noise generated by brush-rotor contact. This results in even greater quietness. Brushless motors include, for example, those with permanent magnets for excitation located on the rotor side and armature windings located on the stator side; and those that use sensors (such as Hall sensors) to detect rotor position signals and provide feedback to an inverter to control current flow, rather than using brushes that change commutator position to switch current flow. Brushless motors, for example, can also be motors that generate a rotating magnetic field by changing the direction of current using switches such as semiconductor switches, thereby rotating the rotor. It should be noted that induction motors can also be motors that generate a sinusoidal wave with a phase offset from the power supply to rotate the magnetic field. Synchronous reluctance motors are a type of synchronous motor that, for example, rotates as an induction motor at startup and synchronizes with the power supply frequency during operation.

[0167] The air flowing through the flow path within the air cylinder portion 603 can be heated by the heater 603d. When the heater 603d is powered on (referred to as the on state), hot air is blown out from the blowout portion 602. When the heater 603d is not powered on (referred to as the off state), cool air that has not been heated by the heater 603d can be blown out from the blowout portion 602. "Heating" means that the temperature of the gas discharged from the area where the heater is installed is higher than the temperature of the gas (e.g., air) before entering the area.

[0168] The hair dryer 601 is provided with an operating unit (not shown in the figure). When using the hair dryer 601, the user operates the operating unit to start or stop the hair dryer 601. In addition, by operating the operating unit, the user can adjust the temperature (hot air / cold air), operating mode, air volume, wind direction, etc. of the air blown out of the air outlet. The above-mentioned operating unit can be set on the main body 604 or on the handle 605. The operating unit may include, for example, a lever, a rocker, etc. When the operating unit includes a lever, a rocker, etc., and the air outlet 602 rotates, if the sliding direction of the lever or rocker corresponds to the rotation direction of the air outlet 602, the user can easily identify the rotation direction of the air outlet 602 by sight or feel. It should be noted that the main body 604 or the handle 605 may also be connected to a power cord (not shown in the figure).

[0169] (Implementation 22) The main body 604 of the hair dryer 1 according to the twenty-second embodiment has a plurality of air outlets and includes a rotating member 604 a for connecting the grip 605 to the main body 604 . Figures 76-79 Schematic diagram schematically showing the appearance of a hair dryer 601 according to Embodiment 22. Figure 76 It is a top view. Figure 77 This is a bottom view. Figure 78 is the main view, Figure 79 It is a side view. Figure 76 、 Figure 77 and Figure 79 This is a schematic diagram showing a first aspect of a hair dryer 601 according to the twenty-second embodiment.

[0170] like Figures 76-78 As shown, the hair dryer 601 of embodiment 22 includes multiple blower sections. The following description uses the example of a hair dryer 601 having a first blower section 621 and a second blower section 622. The first blower section 621 and the second blower section 622 are preferably spaced apart in a direction perpendicular to the first direction (the y-axis). This spacing prevents the airflow from the first blower section 621 and the second blower section 622 from immediately merging, effectively creating the "wrinkle effect" (draping effect) described below. Consequently, airflow from the hair dryer 601 can be efficiently delivered to the hair.

[0171] like Figure 77 As shown, the first blowing portion 621 may have a blowing outlet a on the side wall of the end surface (end wall) opposite to the first air cylinder portion 631, and the second blowing portion 622 may have a blowing outlet a on the side wall of the end surface (end wall) opposite to the second air cylinder portion 632. In addition, the blowing outlet a may be elongated along the first direction.

[0172] The "wrinkle phenomenon" refers to the phenomenon in which hair appears wavy in the area opposite the hair dryer 601 when the hair dryer 601 blows air. For example, when drying hair, when the hair dryer 601 is turned on and air is blown out of each outlet a, radial high-speed regions are formed from each outlet a. Meanwhile, the area between the first and second outlets 621, 622 (more precisely, between each outlet a of the first and second outlets 621, 622) is a closed area where no air is supplied. Air in this closed area is drawn into the high-speed region, resulting in a low-speed region between the outlets a, where air flows toward the hair. This formation of low-speed regions between the high-speed regions generates turbulence in the blown air, creating swirling turbulence in the low-speed regions. This turbulence lifts the hair, allowing for faster drying. Furthermore, the wind blown out from each outlet a hits the scalp and then rebounds, generating wind in a low wind speed region that causes the hair to move away from the scalp and other parts, thereby further generating turbulence.

[0173] Hair blown by air in the high-velocity area is pressed against the scalp (head) by the wind pressure. In contrast, hair in the turbulent low-velocity area is swept up by the turbulent flow and lifted off the scalp (head). As a result, the hair appears wavy in the area opposite the hair dryer 601. In this disclosure, this phenomenon is referred to as the "drape phenomenon." Furthermore, the wind that produces the high-velocity and low-velocity areas that creates the "drape phenomenon" is also referred to as "drape wind."

[0174] The plurality of blowing parts may be arranged on one cylinder part. In addition, the hair dryer 601 may have a plurality of cylinder parts, and the plurality of blowing parts may be arranged on any one of the plurality of cylinder parts. For example, Figures 76-78 As shown, the main body 604 may include a first air cylinder portion 631 and a second air cylinder portion 632, the first blowing portion 621 may be disposed at an end of the first air cylinder portion 631, and the second blowing portion 622 may be disposed at an end of the second air cylinder portion 632. Both the first blowing portion 621 and the second blowing portion 622 may have the same structure as the blowing portion 602 described above.

[0175] The above-mentioned multiple blowing parts are more preferably rotatably arranged on any one of the above-mentioned multiple air cylinder parts. The first blowing part 621 and the second blowing part 622 can be rotatably arranged on the first air cylinder part 631 and the second air cylinder part 632, respectively. In this embodiment, the first blowing part 621 and the second blowing part 622 are rotatably arranged on the first air cylinder part 631 and the second air cylinder part 632, respectively, with the first direction (x-axis direction) as the rotation axis. It should be noted that the first blowing part 621 and the second blowing part 622 can be respectively arranged on the first air cylinder part 631 and the second air cylinder part 632 so as to be movable in the y-axis direction (left and right direction), or can be arranged on the first air cylinder part 631 and the second air cylinder part 632 so as to be movable in the z-axis direction (up and down direction), and can also be arranged on the first air cylinder part 631 and the second air cylinder part 632 so as to be rotatable 360 ​​degrees with the first direction (x-axis direction) as the rotation axis. The first blowing portion 621 and the second blowing portion 622 can be rotated manually or automatically by electric means. The first blowing portion 621 and the second blowing portion 622 can rotate in the same direction or in different directions. In addition, the first blowing portion 621 and the second blowing portion 622 can be integrated with the first air cylinder portion 631 and the second air cylinder portion 632, respectively, so that they cannot be removed, or they can be designed to be installed and removed from the first air cylinder portion 631 and the second air cylinder portion 632.

[0176] The first gas cylinder portion 631 and the second gas cylinder portion 632 may be spaced apart from each other. In this case, the main body 604 may further include a supporting component 604 b for connecting the first gas cylinder portion 631 and the second gas cylinder portion 632 .

[0177] Similar to the embodiment 21, the handle 605 and the main body 604 of the hair dryer 601 of the embodiment 22 are connected in a non-detachable (non-separable) but rotatable manner. Figure 79 As shown, the rotating member 604a can be mounted on the support member 604b of the main body 604, and the grip portion 605 is connected to the main body 604 via the rotating member 604a. By including the rotating member 604a, the hair dryer 601 of Embodiment 22 can adjust the angle of the grip portion relative to the main body 604 between the first and second modes. Since the range of the angle θ1 formed between the extension direction (first direction) of the cylinder portion 603 and the extension direction of the grip portion 605 in the first and second modes is the same as in Embodiment 21, it will not be further described here.

[0178] like Figure 78 As shown, in Embodiment 22, in the first aspect, when the hair dryer 601 is viewed from the first direction, it is also preferred that at least a portion of the grip 605 overlaps with the main body 604 .

[0179] Figure 80 It is a perspective view schematically showing the arrangement position of the grip portion of a hair dryer 601 according to the twenty-second embodiment. Figure 80 The rotating part 604a is omitted. Figure 80 As shown, a plurality of blowing parts (a first blowing part 621 and a second blowing part 622) are arranged along a second direction D2 (y-axis direction) perpendicular to the first direction D1. Let the direction perpendicular to the first direction D1 and the second direction D2 be a third direction D3 (z-axis direction), and the gripping part 605 is preferably arranged in an area formed by rotating the main body 604 along the rotation axis along the third direction D3 and passing through the center of gravity of the main body 604 along the second direction D2, with a line segment having the same length as the width W1 of the main body 604 along the second direction D2 ( Figure 81 The width W1 of the main body 604 is the shortest distance along the y-axis. Positioning the handle 605 within the shaded area allows the handle 605 to be positioned near the center of gravity of the hair dryer 601, thereby reducing the burden on the user.

[0180] Figure 81 2 is a schematic cross-sectional view schematically showing the internal structure of the main body of the hair dryer 601 according to embodiment 22. The plurality of air cylinders preferably have an air inlet, an electric blower, and a heater, respectively. Figure 81 As shown, the first air cylinder portion 631 may include a first air intake port 631b, a first electric blower 631c, and a first heater 631d, and the second air cylinder portion 632 may include a second air intake port 632b, a second electric blower 632c, and a second heater 632d.

[0181] The first air inlet 631b and the second air inlet 632b can both employ the same structure as the air inlet 603b described above. The first electric blower 631c and the second electric blower 632c can both employ the same structure as the electric blower 603c described above. The first heater 631d and the second heater 632d can both employ the same structure as the heater 603d described above. The hair dryer 601 can have separate control boards for the first and second cylinders 631 and 632, or they can be integrated.

[0182] Similar to Embodiment 21, the first blowing portion 621 and the second blowing portion 622 may each be provided with a blowing fin 602a near the blowing outlet a. The blowing fins 602a of the first blowing portion 621 and the second blowing portion 622 may be oriented in different directions.

[0183] The first cylinder portion 631 and the second cylinder portion 632 are preferably symmetrical with respect to a plane (xz plane) passing through the middle of the first cylinder portion 631 and the second cylinder portion 632 and extending in the first direction. For example, at least one of the outer shape of each cylinder portion, the positional relationship between the cylinder portions, the position and shape of each part of each cylinder portion, the flow path area within each blowing portion, the shape and position of the blowing portion, etc. is preferably symmetrical with respect to the above-mentioned xz plane.

[0184] The position of the first air inlet 631b in the first air cylinder portion 631 and the position of the second air inlet 632b in the second air cylinder portion 632 can be the same or different. For example, in order to make the position of the air in the flow path extending direction different during inhalation, the positions of the two can be staggered in the first direction.

[0185] Suction fins (not shown) may be provided adjacent to the first and second air intake ports 631b, 632b, respectively. Suction fins may be provided on each of the first and second air intake ports 631b, 632b, or on only one of the first and second air intake ports 631b, 632b. Multiple suction fins may be provided on each air intake port.

[0186] The position of the first electric blower 631c in the first air cylinder portion 631 and the position of the second electric blower 632c in the second air cylinder portion 632 can be the same or different. When the two are arranged at the same position, it is easier to make the first blowing portion 621 and the second blowing portion 622 blow out air with the same wind speed and temperature.

[0187] By including multiple electric blowers (electric blowers 631c and 632c), the sound produced when blowing a certain air volume can be reduced compared to using a single electric blower to blow the same air volume. This allows the hair dryer to be made quieter overall. Therefore, by including multiple air cylinders, the hair dryer 601 of Embodiment 22 achieves both high air volume and excellent quietness.

[0188] A heater and an electric blower are preferably provided in each flow path of the first air cylinder portion 631 and the second air cylinder portion 632. For example, by making the output (applied power) of each heater and the output (e.g., rotational speed) of each electric blower different, air of different temperatures and air volumes can be blown out from multiple flow paths. Therefore, even if the hair dryer is kept in a fixed position and a fixed posture, low-temperature air and high-temperature air can be blown alternately to multiple adjacent areas, or high-volume air and low-volume air can be blown alternately to multiple adjacent areas. In addition, high-temperature air with a large air volume and low-temperature air with a small air volume, or high-temperature air with a low air volume and low-temperature air with a large air volume can be blown alternately to multiple adjacent areas. Therefore, for example, quick-drying properties can be improved while preventing hair from being damaged.

[0189] In addition, the first electric blower 631c and the second electric blower 632c can rotate in the same direction or in different directions. The rotation directions of the first electric blower 631c and the second electric blower 632c can be controlled to be the same rotation direction or to be controlled to be opposite rotation directions. For example, the rotation direction of the first electric blower 631c and the rotation direction of the second electric blower 632c can also be controlled so that they are in the same direction for a period of time and in opposite directions for another period of time, and so on alternately. The "rotation direction" mentioned here refers to the rotation direction 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).

[0190] For example, by rotating the first electric blower 631c in opposite directions to the second electric blower 632c, the phase of the sound produced by the first electric blower 631c and the second electric blower 632c can be made different or opposite. This allows the sound and vibration produced by each electric blower to cancel each other out, further achieving a quieter effect and reducing vibration in the hair dryer 601. In particular, the fans of each electric blower in two adjacent flow paths are preferably symmetrical in shape. The two electric blowers can rotate in the same or opposite directions.

[0191] The hair dryer 601 may be provided with a distance sensor for measuring the distance between the hair dryer 601 and the hair to be dried. In this case, the hair dryer 601 may control the angle and rotation direction of the plurality of blow-out ports or the plurality of air cylinders according to the distance from the hair.

[0192] It should be noted that Figure 77 The hair dryer 601 shown has a plurality of operation buttons 651 and a power switch 652 as an operation portion, but the hair dryer 601 of Embodiment 22 is not limited to this structure. Figure 77 In the description, an example is given in which the operating portion is provided on the grip portion 605 , but the operating portion may also be provided on the main body 604 .

[0193] (Implementation 23) The main body 604 and the grip 605 of the hair dryer 601 of embodiment 23 are detachable. By changing the mounting position of the grip 605 on the main body 604, the position of the grip 605 relative to the main body 604 can be changed between the first mode and the second mode.

[0194] In embodiment 23, the main body 604 has a main body side mounting portion that enables the holding portion 605 to be mounted in at least the first or second manner, and the holding portion 605 has a holding portion side mounting portion that enables itself to be mounted on the main body 604 in at least the first or second manner.

[0195] Similar to the first embodiment, in the first embodiment of the twenty-third embodiment, the extending direction (first direction) of the cylinder portion 603 forms an angle θ1 with the extending direction of the grip portion 605, and the grip portion 605 can be attached to the main body 604 at an angle of not less than 0° and not more than 30°. In the second embodiment, the above θ1 is greater than θ1 in the first embodiment and is preferably not more than 180°.

[0196] The main body side mounting portion and the holding portion side mounting portion can be connected as long as their shapes match each other and the holding portion 605 can be fixed to the main body 604 when in use. For example, when one of the main body side mounting portion and the holding portion side mounting portion is a convex shape, the other of the main body side mounting portion and the holding portion side mounting portion is preferably a concave shape that can be embedded in the convex mounting portion.

[0197] The main body-side mounting portion of the main body 604 can be located on the end surface opposite to the side where the blowing portion 602 is located, or it can be located on the upper or lower surface of the main body 604. The grip-side mounting portion of the grip 605 can be located at an end in the longitudinal direction of the grip 605, or it can be located on a side surface of the grip 605. The number of main body-side mounting portions and grip-side mounting portions can be one or more, and can also be multiple.

[0198] The following example illustrates a method for connecting the main body 604 and the grip 605 of embodiment 23, but the positions, shapes, and numbers of the main body side mounting parts and the grip side mounting parts are not limited to the following example.

[0199] In the following first example, the main body 604 has two main body side mounting parts, which are used to realize the first and second installation methods respectively, and the gripping part 605 has a gripping part side mounting part that can realize the first and second installation methods.

[0208] (Implementation 24) The main body 604 of the hair dryer 601 of embodiment 24 has multiple air outlets, and the main body 604 and handle 605 are detachable. By changing the mounting position of the handle 605 on the main body 604, the position of the handle 605 relative to the main body 604 can be changed between the first and second modes, as in embodiment 23. Furthermore, because the main body 604 of the hair dryer 601 of embodiment 24 has multiple air outlets, it can produce a "wrinkle effect," similar to embodiment 22, thereby efficiently drying hair.

[0209] Figure 86 This is a side view schematically showing the appearance of a hair dryer 601 according to the twenty-fourth embodiment. Figure 87 24 is a front view schematically showing the appearance of a hair dryer 601 according to the twenty-fourth embodiment. The top view and bottom view of the hair dryer 601 according to the twenty-fourth embodiment are respectively Figure 76 、 Figure 77 The following description will be made using the first example of the embodiment 23 as an example, but the second to fourth examples in the embodiment 23 are also applicable to the embodiment 24.

[0210] like Figure 86 As shown, the main body 604 has a concave main body side mounting portion 301a on the side (back side) of the support member 604b away from the second blowing portion 622, which enables the holding portion 605 to be mounted in the first manner. In addition, the main body 604 has a concave main body side mounting portion 301b below the support member 604b, which enables the holding portion 605 to be mounted in the second manner. It should be noted that Figure 86 In the description, the main body side mounting portions 301a and 301b are arranged on the support member 604b of the main body 604 as an example, but the arrangement position of the main body side mounting portions is not limited to the support member 604b.

[0211] The grip portion 605 has a convex grip portion side mounting portion 501 a at an end portion in the longitudinal direction thereof, which can be mounted on the main body 604 in the first embodiment and the second embodiment.

[0212] In the first embodiment, the grip portion side mounting portion 501a is connected to the main body side mounting portion 301a. In the second embodiment, the grip portion side mounting portion 501a is connected to the main body side mounting portion 301b. Figure 87 As shown, in embodiment 24, in the first aspect, when the hair dryer 601 is viewed from the first direction, at least a portion of the grip 605 preferably overlaps with the main body 604. Also, as in embodiment 22, the grip is preferably disposed near the center of gravity of the main body.

[0213] In Embodiment 24, similar to Embodiment 21, in the first embodiment, the angle θ1 formed between the extension direction (first direction) of the cylinder portion 603 and the extension direction of the grip portion 605 is such that the grip portion 605 can be attached to the main body 604 at an angle of 0° to 30°. In the second embodiment, θ1 is greater than θ1 in the first embodiment and is preferably equal to or less than 180°.

[0214] At least one of the main body 604 and the handle 605 may have a main body side mounting portion or a handle side mounting portion, and a rotating component 604a such as the above-mentioned hinge, universal joint, ball joint, etc.

[0215] Operational components such as operating buttons and a power switch may be provided on the main body 604 or on the grip 605.
