[0012] Preferred embodiments of the present invention will now be described with reference to the drawings. As will be described in detail later, the hair dryer D according to the following embodiment is not a conventional handheld type, but is configured to be worn by the user to dry hair. In this specification, "front" refers to the direction facing the user when viewing the face of the user using the hair dryer D from the front, "back" refers to the direction in which the user is positioned when viewing the face of the user using the hair dryer D from the front, "right" refers to the direction to the right of the user when viewing the face of the user using the hair dryer D from the front, "left" refers to the direction to the left of the user when viewing the face of the user using the hair dryer D from the front, "up" refers to the direction above the user when viewing the face of the user using the hair dryer D from the front, and "down" refers to the direction below the user when viewing the face of the user using the hair dryer D from the front.

[0013] First Embodiment [Overall configuration of Hair Dryer D] 1 to 3, the hair dryer D according to this embodiment has the appearance of a so-called hoodie-like garment and is designed to be worn by a user. The hair dryer D mainly includes a vest 10 that covers the upper half of the user's body when worn, and a hood 20 that is sewn to the vest 10, covers the user's head and neck when worn, and functions as a hair dryer.

[0014] [Vest 10] The vest 10 is a sleeveless cloth vest that covers the upper half of the user's body when wearing the hair dryer D. The vest 10 also has power supply pockets 11 at the upper left and upper right parts of the front of the vest 10 for accommodating batteries (power sources, not specifically shown) that supply power to the air blower 22, which will be described later. In this embodiment, the vest 10 is configured as a vest, but this is not limited thereto. For example, the vest 10 may be configured as a long-sleeved or short-sleeved shirt. The material of the vest 10 is also not particularly limited. For example, natural fibers such as cotton, linen, and wool may be used, or chemical fibers such as nylon, polyester, and rayon may be used. In this embodiment, two power supply storage pockets 11 are provided on the upper left and right sides of the front of the vest 10. However, the location and number of the power supply storage pockets 11 are not limited thereto. For example, one or more power supply storage pockets 11 may be provided on the upper front, center front, lower front, upper back, center back, lower back, etc. of the vest 10.

[0015] [Food 20] The hood 20 is a hood-like member sewn to the vest 10, which covers the head and neck of the user when the hair dryer D is worn and also functions as a dryer. The hood 20 mainly includes a cloth lining 21a which covers the head and neck of the user when the hair dryer D is worn, a cloth outer layer 21b which is detachably attached to the lining 21a, an air blower 22 which generates an air current and blows air, and a cloth air guide duct 23 which is sewn to the lining 21a while being sandwiched between the lining 21a and the outer layer 21b and which guides the air blown out from the air blower 22 (through which the air blown out from the air blower 22 passes).

[0016] In the present embodiment, as described above, the lining 21a, the outer fabric 21b, and the air guide duct 23 are all made of fabric, and the hood 20 is formed by sandwiching the air guide duct 23 between the lining 21a and the outer fabric 21b, sewing the air guide duct 23 to the lining 21a, and attaching the outer fabric 21b to the lining 21a. When the hair dryer D is worn, the hood 20 covers the user's head and neck except for the surface of the face. Furthermore, when the outer fabric 21b is attached to the lining 21a, an opening (not shown) is formed in the hood 20 in a portion that would correspond to the user's neck when wearing the hair dryer D, and the outer edge of the hood 20 other than the opening is closed by the lining 21a and the outer fabric 21b, so that the hood 20 becomes bag-shaped and an internal space is defined between the lining 21a and the outer fabric 21b. As a result, the outside and inside of the hood 20 (the internal space defined between the lining 21a and the outer surface 21b) are in communication with each other through the opening. The air guide duct 23 is disposed within this internal space.

[0017] The lining 21a is a fabric that covers the user's head and neck when wearing the hair dryer D and is sewn to the vest 10 so as to be non-detachable (inseparable). As shown in FIG. 4(A), the lining 21a is provided with lining ventilation holes 21a1 that penetrate from the lower surface (the surface facing the user's head) to the upper surface (the surface facing the lower surface) of the lining 21a at positions corresponding to air duct ventilation holes 23b1 provided in the air ducts 23 described below. The lining ventilation holes 21a1 pass through the air blown out from the air duct ventilation holes 23b1. The lining also has lining hearing holes 21a2 that penetrate from the lower surface to the upper surface of the lining 21a at positions corresponding to the user's left and right ears (left and right parts of the lining 21a), respectively. The lining hearing holes 21a2 penetrate from the lower surface to the upper surface of the lining 21a and allow the user to easily hear sounds and voices occurring outside the hood 20. In addition, a plurality of electric heating pads 24 are arranged on the upper surface of the lining 21a to generate heat and warm the user's head and hair. The lining 21a is made of cotton, which has excellent water absorption and heat generation properties. The material of the lining 21a is not particularly limited, and may be natural fibers such as hemp or wool, or chemical fibers such as nylon or rayon. The lining 21a and the vest 10 are sewn together and cannot be removed, but this is not a limitation. For example, the lining 21a may be attached to the vest 10 with a hook-and-loop fastener or the like, making it detachable (separable). The electric heating pad 24 may be disposed on the underside of the lining 21a, rather than on the top side. The electric heating pad 24 need not be provided.

[0018] Outer fabric 21b is the outermost fabric of hood 20 and constitutes the exterior of hood 20. It overlaps the top surface of lining fabric 21a and is detachably (separably) attached to lining fabric 21a with a hook-and-loop fastener (not shown). Outer fabric 21b has outer fabric listening holes 21b1 at positions corresponding to lining fabric listening holes 21a2 in lining fabric 21a, which penetrate from the bottom surface (the surface facing lining fabric 21a) to the top surface (the surface facing the bottom surface) of outer fabric 21b and allow for easy audible detection of sounds and voices occurring outside hood 20. Because lining fabric listening holes 21a2 and outer fabric listening holes 21b1 connect the outside and inside of hood 20, the user can easily hear sounds and voices outside hood 20 even when wearing hair dryer D and the hood 20 covers the user's head. Furthermore, polyester, which has excellent heat retention properties, is used as the material for outer fabric 21b. The material of outer fabric 21b is not particularly limited, and may be natural fibers such as cotton, linen, or wool, or chemical fibers such as nylon or rayon. While outer fabric 21b and lining fabric 21a are detachably attached using a hook-and-loop fastener, the present invention is not limited to this and may be detachably attached using snap buttons or a fastener, or may be sewn together to prevent removal. Lining fabric listening hole 21a2 and outer fabric listening hole 21b1 may be formed to fit together, preventing misalignment of hair dryer D when worn.

[0019] The air blower 22 is a device for generating and blowing an air current, and although not specifically shown, includes an air intake port for taking in air, a fan for generating and blowing an air current, an air outlet for blowing out the air, a motor for driving the fan, a heat source such as a heating wire, a switch for switching the motor and heat source on and off, and a cable for connecting to a battery (power source) that supplies power. The air blower 22 generates warm air by passing the air current generated by driving the fan through the heat source that generates heat, and can blow out the warm air through the air outlet. The air blower 22 is detachably (separably) attached to the top surface of the outer material 21b near the opening of the hood 20 by a hook-and-loop fastener (not specifically shown). Note that instead of being detachably attached to the upper surface of outer material 21b near the opening of hood 20, blower 22 may be detachably attached to the underside of outer material 21b or the upper surface of lining 21a near the opening of hood 20. Also, instead of supplying power from a battery, power may be supplied from a wiring outlet provided on the wall of the room, etc. Furthermore, it is desirable to provide the switch for the air blower 22 in a predetermined position on the front of the vest 10 (for example, near one of the power supply storage pockets 11 (upper left and right sides of the front of the vest 10), or in an area corresponding to the position of the user's hands when the user has their arms down (lower left and right sides of the front of the vest 10)) so that it is easy for the user to operate. Note that the switch for the air blower 22 may be provided in a predetermined position on the hood 20 instead of on the vest 10.

[0020] Air guide duct 23 is a tubular member made of fabric that guides the air sent out from blower 22, and constitutes a passage through which the air sent out from blower 22 passes. As described above, air guide duct 23 is sandwiched between lining 21a and outer fabric 21b (i.e., disposed in the above-mentioned internal space formed between lining 21a and outer fabric 21b in hood 20) and sewn to lining 21a so as not to be detachable. Furthermore, polyester is used as the material for air guide duct 23.

[0021] As shown in Figures 5 to 7, the air guide pipe 23 has a connecting pipe 23a connected to the blower 22 and a main pipe 23b connected to the connecting pipe 23a, and the blower 22 and the main pipe 23b are connected via the connecting pipe 23a.

[0022] Connecting pipe 23a is a tubular member made of cloth that connects blower 22 and main pipe 23b. One end of connecting pipe 23a is provided with connecting port 23a1 that is detachably connected to an air outlet (not specifically shown) of blower 22, and the other end of connecting pipe 23a is connected to air inlet 23b2 of main pipe 23b, which will be described later. In other words, connecting pipe 23a and main pipe 23b are in communication, and air sent out from blower 22 is sent to main pipe 23b via connecting pipe 23a. Furthermore, as described above, connecting pipe 23a is made of cloth and is expandable and deformable, so that its inner diameter changes depending on whether or not air is passing through it from blower device 22. Specifically, in a normal state (when air is not being blown out from blower device 22 and no air is passing through connecting pipe 23a), no wind pressure is applied to the inner wall of connecting pipe 23a, so connecting pipe 23a is in a reduced diameter state. However, when air is being blown out from blower device 22 and air is passing through connecting pipe 23a, wind pressure applies outward pressure to the inner wall of connecting pipe 23a, causing connecting pipe 23a to expand and become larger in diameter. In other words, connecting pipe 23a expands when air from blower device 22 passes through it.

[0023] Main tube 23b is a circular, tubular member made of fabric that, when hood 20 covers the user's head and neck, forms a passage through which air passes from the lower back of the user's head, through the upper left side of the head, a position slightly closer to the front of the head than the top of the head (above the forehead), and the upper right side of the head, and then returns to the lower back of the head (see Figures 1, 4(b), 8, etc.). Main tube 23b is provided with air inlet 23b2 at a position that corresponds to the lower back of the user's head when hood 20 covers the user's head and neck, and this air inlet is connected to connecting tube 23a. As described above, main tube 23b is sewn to lining 21a, and main tube 23b and lining 21a are in surface contact with each other. On the surface of main tube 23b that contacts lining 21a, air guide tube vents 23b1 are provided at positions corresponding to the vicinity of the lower back of the user's head (near the air inlet) when covered by hood 20, the upper left side of the head, a position slightly closer to the forehead than the top of the head, and the upper right side of the head, which are holes that penetrate the contact surface of lining 21a and through which air passing through main tube 23b is blown out. As described above, the lining 21a has lining ventilation holes 21a1 at positions corresponding to the air guide pipe ventilation holes 23b1, and since the air guide pipe ventilation holes 23b1 and the lining ventilation holes 21a1 are connected, the air passing through the main body pipe 23b is blown out from the lining ventilation holes 21a1 via the air guide pipe ventilation holes 23b1. Like connecting pipe 23a, main pipe 23b is also made of cloth and is expandable and deformable, so that its inner diameter changes depending on whether or not air is passing through it from blower 22. That is, in a normal state (when air is not being blown out from blower 22 and no air is passing through connecting pipe 23a), no wind pressure is applied to the inner wall of main pipe 23b, so main pipe 23b is in a reduced diameter state. However, when air is being blown out from blower 22 and passing through main pipe 23b, the wind pressure applies outward pressure to the inner wall of main pipe 23b, causing main pipe 23b to expand and expand in diameter. That is, main pipe 23b expands when air from blower 22 passes through it.

[0024] Although polyester is used as the material for air guide tube 23 (connecting tube 23a, main tube 23b), there is no particular limitation as long as it is stretchable and deformable and can expand (bulge) due to wind pressure when air from blower device 22 passes through. For example, chemical fibers such as nylon and rayon, or natural fibers such as cotton, linen, and wool may be used, and the material may be vinyl instead of fabric. Furthermore, lining ventilation hole 21a1 and air guide tube ventilation hole 23b1 may be formed so as to be able to fit together, or the peripheries of the two may be fixed together (for example, fixed with a predetermined fastener or sewn together) to prevent misalignment when hair dryer D is in use.

[0025] [How to use Hair Dryer D] Next, a method of using the hair dryer D according to this embodiment will be described. As described above, the hair dryer D according to this embodiment is worn by a user. Specifically, when starting to use the hair dryer D, the user puts on the vest 10 and puts on the hood 20 so as to cover their head. As a result, the lining 21a of the hood 20 covers the user's head and neck.

[0026] When the user's head and neck are covered with lining 21a of hood 20, main tube 23b of air guide tube 23, which is sandwiched between lining 21a and outer layer 21b inside hood 20, is positioned to pass through the lower back of the head, the upper left side of the head, a position slightly closer to the front of the head than the top of the head (above the forehead), and the upper right side of the head of the user. Accordingly, air guide tube ventilation holes 23b1 of main tube 23b are positioned at positions corresponding to the vicinity of the lower back of the head of the user (near the air inlet), the upper left side of the head, a position slightly closer to the front of the head than the top of the head, and the upper right side of the head, and lining ventilation holes 21a1 provided in lining 21a are positioned corresponding to these positions, respectively.

[0027] When the switch of the blower 22 is then turned on, the heat source generates heat and the fan rotates, thereby generating warm air W, which is blown from the blower 22 through the connecting pipe 23a and into the main pipe 23b. As described above, when the warm air W is blown out from the blower 22 and passes through the connecting pipe 23a and the main pipe 23b, an outward wind pressure is applied to the inner walls of these pipes, causing the inner diameters of the connecting pipe 23a and the main pipe 23b to expand. This increases the flow rate of the warm air W passing through the connecting pipe 23a and the main pipe 23b. The warm air W passing through the main pipe 23b is then blown out toward the user's head, which is covered by the lining 21a, through the air guide pipe ventilation holes 23b1 and the lining ventilation holes 21a1, thereby drying the user's hair. The air duct ventilation holes 23b1 and the lining ventilation holes 21a1 are located in areas of the head where there is a large amount of hair and where wet hair is difficult to dry.

[0028] As described above, the hair dryer D according to this embodiment has the fabric air guide 23 (connecting tube 23a, main tube 23b) sewn to the lining 21a of the hood 20, which is worn to cover the user's head and neck. Air from the blower 22 is blown onto the user's hair through the air guide 23, and as the air passes through the air guide 23, the inner diameter of the air guide 23 expands due to wind pressure. This increases the flow rate of air passing through the air guide 23, allowing more air to be blown onto the user's hair, thereby enabling the user's hair to dry quickly. Furthermore, when no air is passing through the air guide 23, the inner diameter of the air guide 23 shrinks, allowing the hood 20 to be folded compactly. Thus, the hair dryer D according to this embodiment allows for efficient hair drying without using hands, as with conventional handheld hair dryers, and can be stored compactly when not in use, improving convenience.

[0029] Furthermore, the outer fabric 21b, which corresponds to the exterior of the hair dryer D, can be attached and detached to the lining fabric 21a with a hook-and-loop fastener. Therefore, the exterior design of the hair dryer D can be easily changed by simply changing the outer fabric 21b while leaving the lining fabric 21a and the air guide duct 23 as they are. For example, if the product is aimed at women, the outer fabric 21b can be decorated with a cute design, and if the product is aimed at children, the outer fabric 21b can be decorated with an anime character. This makes it easy to design hair dryers D with a wide variety of designs.

[0030] Furthermore, since a plurality of electric heating pads 24 are provided on the lining 21a, the user's head can be warmed while the hair is dried, thereby enhancing the relaxation effect while the hair is being dried.

[0031] In addition, in the hair dryer D according to this embodiment, the battery that supplies power to the blower device 22 is accommodated in the power supply accommodating pocket 11 provided in the vest . Here, it is possible to place the battery in the hood 20 instead of the vest 10, but since the battery is relatively heavy, if it is placed in the hood 20, the weight of the battery will pull the hood 20 downward, compressing the main tube 23b, which is expanded by wind pressure, and causing it to shrink in diameter, reducing the air flow rate inside the main tube 23b and ultimately making it difficult for the wind to blow onto the user's hair. Therefore, in the hair dryer D according to this embodiment, the battery that supplies power to the blower device 22 is accommodated in the power supply accommodation pocket 11 provided in the vest 10, thereby preventing the above situation.

[0032] A collar 14 may be provided around the neck of the vest 10. For example, a collar 14 that covers the entire circumference of the neck (see FIG. 9(A)) or a collar 14 that covers both sides and the back of the neck (see FIG. 9(B)) may be provided. This prevents the user from feeling uncomfortable when wet hair sticks to the neck when using the hair dryer D.

[0033] In addition, in this embodiment, the main body tube 23b, which is placed on the user's head and can blow air onto the user's hair, has a circular ring shape, but this is not limited to this. For example, main tube 23b may have a straight tube section extending from a position slightly closer to the forehead than the crown to the lower back of the head in addition to the circular tube section as in the present embodiment, and air guide tube ventilation holes 23b1 may also be provided in this straight tube section (see FIG. 10(A)). This increases the number of areas onto which air from blower 22 blows, making it possible to dry hair more efficiently. Alternatively, main tube 23b may be configured without a circular tube portion, consisting only of a band-shaped tube portion extending from a position slightly closer to the forehead than the crown to the lower back of the head, with air guide tube ventilation holes 23b1 provided in this band-shaped tube portion (see FIG. 10(B)). This allows main tube 23b to be made more compact than if it were ring-shaped, and makes it possible to reduce the weight of hood 20. This reduces the strain on the user's neck when using hair dryer D and also reduces the manufacturing costs of hair dryer D. Furthermore, the member placed on the user's head and capable of blowing air onto the user's hair may not be a tubular member like the main tube 23b of this embodiment, but may be a planar member (not shown) that covers the entire head of the user. For example, without providing the air guide tube 23, the lining 21a may be used as the planar member, and air may be blown directly from the air blower 22 into the internal space defined by the lining 21a and the outer layer 21b, so that the air is blown toward the user's head through the lining ventilation holes 21a1 of the lining 21a. However, if such a planar member is used, the air from the air blower 22 will be diffused, weakening the air blown out from the lining ventilation holes 21a1. Therefore, a tubular member is preferable.

[0034] In the present embodiment, air guide duct 23 is formed as a tubular member whose entire outer periphery is covered with a surface, and the outer periphery of air guide duct 23 and lining 21a are sewn together in an overlapping state (see FIG. 11(A)), but this is not limited to this. For example, air guide duct 23 may be formed as a semi-tubular member (a member shaped like a so-called half-split pipe) whose outer periphery is partially open, and the open portion on the outer periphery of air guide duct 23 may be sewn together so as to close it with lining 21a, so that the tubular member is formed by air guide duct 23 and lining 21a (see FIG. 11(B)).

[0035] In the present embodiment, the air guide duct 23 is provided in the internal space formed between the lining 21a and the outer fabric 21b, but this is not limiting. For example, as shown in FIGS. 12(A) and 12(B), the air guide duct 23 may be provided (sewn) directly on the underside of the lining 21a (the surface facing the user's head). Alternatively, as shown in FIGS. 13(A) and 13(B), a base fabric B with the air guide duct 23 sewn thereon may be attached (sewn) to the underside of the lining 21a, thereby providing the air guide duct 23 indirectly on the underside of the lining 21a via the base fabric B. In this case, the hair dryer D can be easily manufactured by using a ready-made parka-like garment and attaching the air guide duct 23 and the blower 22 to the garment. Furthermore, the outer fabric 21b may not be attached to the inner fabric 21a, and the air duct 23 sewn to the inner fabric 21a may be exposed.

[0036] In the present embodiment, the blower 22 is provided with a heat source so that it can blow out hot air, but this is not limiting. For example, a switch on the blower 22 may be set to switch between enabling and disabling the heat source to generate heat, thereby switching between blowing out hot air and blowing out room-temperature air. Alternatively, the air blower 22 may be configured to blow only room-temperature air without providing a heat source. When the user wears the hood 20, heat from the user's scalp and hair is trapped inside the hood 20. In this embodiment, the provision of the electric heating pad 24 and the use of cotton, which has excellent heat-generating properties, in combination with the lining of the hood 20, warms the air inside the hood 20. When the air from the air blower 22 is blown onto the user's hair, this air convects within the hood 20. Therefore, even when only room-temperature air is blown from the air blower 22 as described above, the user's hair can be dried by the convection of air heated by the user's body temperature and the electric heating pad 24, while preventing the inside of the hood 20 from becoming too hot. Incidentally, if the electric heating pad 24 is disposed near the air duct 23, the air before being blown out of the air duct 23 is heated to some extent, allowing for more efficient drying of the user's hair.

[0037] In addition, as shown in Figures 14(A) and (B), the hood 20 may be provided with a support rib SB made of resin such as plastic, which will help the hood 20 maintain its shape when the user wears the hood 20. Specifically, for example, a support rib SB1 may be provided extending from the left end of the opening of the hood 20 to the right end of the opening so as to surround the back of the user's neck when the user wears the hood 20, and a support rib SB2 may be provided extending from the left end of the opening to the right end of the opening of the hood 20 so as to surround the user's face. The support rib SB may be provided on the inner lining 21a or the outer lining 21b of the hood 20, or may be provided between the inner lining 21a and the outer lining 21b. The support ribs SB provided on the hood 20 are not limited to these. For example, only the support rib SB1 may be provided, or in addition to the support ribs SB1 and SB2, one or more support ribs SB may be provided between the support ribs SB1 and SB2. In this case, even when the battery weakens or the blower device 22 deteriorates and the blower device 22 is unable to blow air sufficient to fully open the air guide tube 23, the support ribs SB support the hood 20, making it easier to open the air guide tube 23. In addition, the support bone SB may be attached to the hood 20 so that it can rotate freely around a predetermined rotation axis RA, so that it can rotate together with the hood 20 when the hood 20 is folded after being taken off (see Figure 14(A)).

[0038] In addition, in the present embodiment, the hair dryer D includes the vest 10 and the hood 20, but the present invention is not limited to this. For example, the hair dryer D may include only the hood 20.

[0039] <Second embodiment> [Overall configuration of Hair Dryer D] Next, a second embodiment will be described. In the following, in principle, only the configurations that differ from those of the first embodiment described above will be explained, and the same configurations will be assigned the same reference numerals and explanations thereof will be omitted.

[0040] As shown in FIGS. 15 to 18, the hair dryer D according to this embodiment includes an attachment 30 in addition to a vest 10 and a hood 20. As shown in FIGS.

[0041] [Attachment 30] Attachment 30 is attached to connecting pipe 23a of blower device 22 and air guide duct 23, and is a plastic member that is U-shaped in plan view for guiding the air blown out from blower device 22 toward air guide duct 23 (the user's head) and in a direction different from air guide duct 23 (see FIGS. 18 and 20). Attachment 30 is formed so that it can be placed on the back of the neck and shoulders of the user, and is used by attaching connecting pipe 23a of blower device 22 and air guide duct 23 while the attachment is placed on the back of the neck and shoulders (see FIG. 21).

[0042] The attachment 30 is mainly composed of a base 31, a shoulder rest 32, a protrusion 33, an outlet 34, a blower attachment 35, and an air guide tube attachment 36.

[0043] The base 31 serves as the base of the attachment 30, and has a cavity 31a inside (see FIG. 19). Air from the air blower 22 attached to an air blower attachment portion 35 (described later) is blown into the cavity 31a inside the base 31.

[0044] The shoulder rest part 32 is the part that is placed on the shoulder of the user and corresponds to the bottom surface of the base part 31. The shoulder rest part 32 has a curved surface that is gently convex upward in side view as shown in Fig. 19 .

[0045] Protrusion 33 is a portion located on the back of the user's neck (a portion that covers the back of the user's neck), protrudes upward from the upper surface of base 31 (see FIG. 19), and has a curved shape that follows the line of the neck in a plan view (see FIG. 18). The interior of protrusion 33 is hollow 33a, which communicates with hollow 31a inside base 31. An end surface 33b is formed at the end (upper end) of protrusion 33 in the protruding direction, and this end surface 33b is provided with a plurality of blowing holes 33c that communicate with hollow 33a (see FIG. 18). Air from blower 22 passes through hollow 31a inside base 31 and hollow 33a inside protrusion 33 and is blown out from blowing holes 33c.

[0046] The blowing section 34 is for blowing out air from the blower 22, and includes a left blowing section 34L and a right blowing section 34R provided on the left and right sides of the base 31, respectively. As shown in FIG. 18, the left blowing section 34L and the right blowing section 34R are both nozzle-shaped members extending forward from the base 31. The left blowing section 34L has a cavity 34La inside, and the right blowing section 34R has a cavity 34Ra inside, both of which are connected to the cavity 31a inside the base 31 (see FIG. 18). Furthermore, the tip of the left blowing section 34L is provided with a left blowing outlet 34Lb that communicates with the cavity 34La, and the tip of the right blowing section 34R is provided with a right blowing outlet 34Rb that communicates with the cavity 34Ra. The air from the blower 22 is blown out from the left air outlet 34Lb through the cavity 31a inside the base 31 and the cavity 34La of the left air outlet 34L, and is blown out from the right air outlet 34Rb through the cavity 31a inside the base 31 and the cavity 34Ra of the right air outlet 34R.

[0047] The air blower attachment portion 35 is a portion to which the air blower 22 is detachably attached, and is provided at the rear lower portion of the base 31 (see FIG. 18). An air outlet (not specifically shown) of the air blower 22 can be connected to the air blower attachment portion 35. The air guide pipe attachment portion 36 is a portion to which the connecting pipe 23a of the air guide pipe 23 is detachably attached, and is provided at the rear upper portion of the base 31. The air guide pipe attachment portion 36 is designed to be connectable to the connecting port 23a1 of the connecting pipe 23a. Then, when the blower 22 is attached to the blower attachment portion 35 and the connecting pipe 23a of the air guide pipe 23 is attached to the air guide pipe attachment portion 36, and the switch of the blower 22 is turned on, the air from the blower 22 is blown into the cavity 31a inside the base 31, and is also blown into the main pipe 23b via the cavity 31a and the connecting pipe 23a.

[0048] Although the attachment 30 is made of plastic, the material is not particularly limited as long as it can guide the air from the air blower 22. For example, it may be made of cloth or wood.

[0049] [How to use Hair Dryer D] Next, a method of using the hair dryer D according to this embodiment will be described. The hair dryer D according to this embodiment is also worn by a user, similar to the hair dryer D according to the first embodiment. In this embodiment, before use, the attachment 30 is placed near the position where the vest 10 and the hood 20 are sewn together, the air blower 22 is attached to the air blower attachment portion 35, and the connecting pipe 23a of the air duct 23 is attached to the air duct attachment portion 36.

[0050] When starting to use the hair dryer D, the user puts on the vest 10, places the shoulder rests 32 of the attachment 30 on their shoulders, and then puts on the hood 20 so that it covers their head. As a result, the back of the user's neck and shoulders are covered by the protrusions 33 of the attachment 30, and the left outlet 34Lb of the left outlet 34L and the right outlet 34Rb of the right outlet 34R of the attachment 30 are positioned slightly forward of the user's shoulders. The user's head and neck are also covered by the lining 21a of the hood 20.

[0051] Then, when the switch of the blower 22 is turned on, the heat source generates heat and the fan rotates, and the warm air W generated thereby is blown out from the blower 22 into the cavity 31a inside the base 31 of the attachment 30, and also into the main pipe 23b via the base 31 and the connecting pipe 23a. As in the first embodiment, when hot air W is blown out from blower 22 and passes through connecting pipe 23a and main pipe 23b, outward wind pressure is applied to the inner walls of these pipes, causing the inner diameters of connecting pipe 23a and main pipe 23b to expand, increasing the flow rate of hot air W passing through connecting pipe 23a and main pipe 23b. The hot air W passing through main pipe 23b is blown out toward the user's head, which is covered by lining 21a, via air guide pipe ventilation holes 23b1 and lining ventilation holes 21a1, thereby drying the user's hair. Meanwhile, the warm air W blown into the cavity 31a inside the base 31 is blown out of the attachment 30 via the cavity 33a inside the protrusion 33 and the outlet holes 33c. As described above, the protrusion 33 is designed to cover the back of the user's neck, and the outlet holes 33c are located near the nape of the neck. The nape of the neck is covered by the back hair, making it difficult for air to pass through and difficult to dry. However, with the attachment 30 of this embodiment, the warm air W can be blown directly onto the nape of the neck, improving drying efficiency. The warm air W is blown out of the attachment 30 through the cavity 34La and the left outlet 34Lb of the left outlet 34L, and is also blown out of the attachment 30 through the cavity 34Ra and the right outlet 34Rb of the right outlet 34R. As described above, the left outlet 34Lb and the right outlet 34Rb are positioned slightly forward of the user's shoulders, and if the user's hair reaches the shoulders, they will be located at the ends of the hair. The ends of the hair are difficult to dry, but with the attachment 30 of this embodiment, the warm air W can be blown directly onto the ends of hair that reaches the shoulders, improving drying efficiency.

[0052] As described above, the hair dryer D according to this embodiment is equipped with an attachment 30 that can blow air into the main body tube 23b and also blow air from the blower device 23 onto the ends of hair that extends down to the nape and shoulders, thereby improving the drying efficiency of areas that are difficult to dry and increasing convenience.

[0053] Although the present invention has been described in the above-mentioned embodiments, it is not limited to these. Modifications, changes, and changes in the combination of each component element can be made within the scope that can achieve the object of the present invention. Furthermore, the first embodiment, the second embodiment, and modifications of each embodiment may be combined.
