As shown in FIG. The second ventilation port 42 is configured as a slit-like opening formed substantially over the entire circumference of the wall surface near the front end of the front reflector 37 when the pair of half-split bodies 37a and 37b are assembled. Although the front reflector 37 is composed of a pair of half-split bodies 37a and 37b, the front reflector 37 can also be composed of a single deformed cylindrical body. The front reflector 37 in this case is formed by a die-cast molding made of metal such as aluminum.

The rear reflector 38 is formed of a die-cast molded product made of aluminum. ) is provided with a concave mirror-like third reflecting surface 43 that reflects and guides the light forward toward ), and the inner surface thereof is polished to form a mirror-like reflecting surface. The third reflecting surface 43 can also be made into a specular reflecting surface by plating.

A light source support structure for supporting the halogen lamp 28 is provided behind the third reflecting surface 43 . The light source support structure includes a light source base 45 consisting of four bosses for supporting the halogen lamp 28, and a hexagonal cylinder-shaped wind guide wall 46 surrounding the light source base 45. are fastened and fixed to each light source stand 45 with four screws 47 together with a wiring board 49 . A first vent hole 48 is formed in the center of the third reflecting surface 43 to introduce dry air into the reflector 29 . A light source cooling passage is formed between the air guide wall 46 and the halogen lamp 28 and communicates with the first air vent 48 . The wiring board 49 temporarily collects leads for supplying electric power to the halogen lamp 28 extending from the inside of the grip 12 to the inside of the wind guide tube 7 and leads for supplying electric power to the fan motor 2, and distributes the leads from there. are placed in Further, the wiring board 49 functions as a light shielding plate for preventing the light leaking from the first air vent 48 from being radiated to the suction port 10 side.

The front reflector 37 and the rear reflector 38 are joined and fastened so that the second reflecting surface 40 and the third reflecting surface 43 are adjacent to each other. In order to fasten and fix both reflectors 37 and 38, front engaging portions (protrusions) 51 are bent and formed on the rear edges 57 of the half bodies 37a and 37b so as to protrude in the radial direction. A joining groove 52 for fitting and supporting the rear edge 57 of the front reflector 37 and a joining wall 53 for supporting the peripheral surface of the rear edge 57 of the front reflector 37 are formed at the front end of the rear reflector 38 . A recessed rear engaging portion 54 and a screw boss 55 are formed by notching the joint wall 53 at two opposite locations of the wall 53 . The front reflector 37 and the rear reflector 38 can be joined by joining the pair of half-split bodies 37a and 37b and engaging the front engaging portion 51 and the rear engaging portion 54 in an uneven manner. Further, by screwing a screw 56 inserted through the through hole 51a of the front engaging portion 51 into the screw boss 55, the front reflector 37 and the rear reflector 38 can be integrated. When the halogen lamp 28 is assembled to the reflector 29, the center of the filament of the halogen lamp 28 faces the adjacent portion between the second reflecting surface 40 and the third reflecting surface 43 (see FIG. 4).

As described above, the front reflector 37 and the rear reflector 38 are prevented from shifting in the radial direction by the engagement between the rear edge 57 of the front reflector 37 and the joint groove 52 . Rotation around the central axis P is prevented by the engagement of the engaging portion 54 . Note that the front engaging portion 51 can also be configured by a projection that protrudes radially from the rear edges of the half bodies 37a and 37b. Also, the front reflector 37 may be composed of a single reflecting tube. In that case, it can be composed of a die-cast molded product made of metal such as aluminum. Also, the front engaging portion 51, the rear engaging portion 54, and the screw 56 do not have to be provided at two opposing locations, and can be configured at only one location. The front reflector 37 may be configured by joining three or more divided bodies.

Filter 30 is formed of low expansion glass and is secured to the front end of front reflector 37 with a filter support structure. The filter support structure consists of a filter seat 41 formed on the front reflector 37 and a pressing ring 60 which cooperates with the filter seat 41 to clamp and fix the filter 30 in the front and rear direction. The retaining ring 60 includes an end wall 61 that presses and holds the front peripheral edge of the filter 30, and a ring-shaped surrounding wall 62 that fits around the outer peripheral surface of the filter receiving seat 41. It functions as a glare 75 . As shown in FIG. 4, the retaining ring 60 is fixed to the front reflector 37 with screws 63. As shown in FIG. The filter seat 41 is in close contact with the peripheral surface and rear peripheral edge of the filter 30 . Thereby, the heat of the filter 30 can be effectively conducted to the front reflector 37 side, and the cooling of the filter 30 can be promoted.

The halogen lamp 28 is weak against impact, and the filament is broken or deformed when a large external force acts on it. The heat source unit 4A is float-supported with respect to the main body case 1 in order to prevent impact from acting on the halogen lamp 28. As shown in FIG. Specifically, as shown in FIG. 9, a hexagonal frame-shaped spring receiving frame 64 for supporting the heat source unit 4A is fixed to the inner surface of the air guide tube 7 surrounding the light source support structure. Shock absorbing springs 65 for supporting the heat source unit 4A are arranged at three locations on the facing surface. A hexagonal frame-shaped unit support frame 66 that supports the heat source unit 4A is fixed to the inner surface of the air guide tube 7 surrounding the filter 30, and the anti-glare body 75 described later and the unit support frame 66 face each other. A gel-like elastic body 67 having viscoelasticity for supporting the heat source unit 4A is arranged at the location.

The spring receiving frame 64 is constructed by connecting three spring arms 70 made of leaf springs in a hexagonal frame shape. is formed. A spring seat 72 for receiving the other end of the shock absorbing spring 65 is also formed on the wind guide wall 46 of the rear reflector 38 facing the spring seat 71 . The unit support frame 66 is formed of a leaf spring in the shape of a hexagonal frame, and gel holding portions 73 for holding the gel elastic body 67 are formed at three positions. As described above, in the heat source unit 4A floatingly supported by the main body case 1, the spring receiving frame 64 and the shock absorbing spring 65 are elastically deformed, the unit supporting frame 66 is elastically deformed, and the gel-like elastic body 67 absorbs the shock. By doing so, the shock is mitigated and absorbed to prevent the halogen lamp 28 from being affected by the shock. Therefore, even if the main body case 1 collides with another object and receives an external impact, most of the external impact is absorbed by the impact absorbing spring 65 and the gel-like elastic body 67, and the heat source unit 4A is impacted. can be prevented from working. Since the halogen lamp 28 can be well prevented from being damaged due to external shock or external vibration, the light emitting function of the halogen lamp 28 can be properly exhibited for a long period of time.

When in use, the halogen lamp 28 is lit, the blower fan 3 is driven, the infrared light that has passed through the filter 30 is applied to the hair, and the dry air generated by the blower fan 3 is supplied to the hair. Dry your hair. Part of the dry air is introduced into the air guide wall 46 through the rear opening 58, flows into the first air vent 48 from the light source cooling passage, cools the halogen lamp 28, the reflector 29, and the filter 30, and then cools the second air. It flows out of the reflector 29 through the air vent 42 , joins with the dry air flowing through the air guide passage 9 , and is sent out from the air outlet 11 . Part of the dry air supplied from the blower fan 3 creates a negative pressure state around the second vent 42 while flowing along the air guide passage 9 (annular air passage 35) around the heat source unit 4A. to Therefore, due to the venturi effect, the air in the vicinity of the second vent 42 inside the reflector 29 is attracted to the drying air, joins it, and is sent out to the outlet 11 . The dry air that has cooled the halogen lamp 28, the reflector 29, and the filter 30 is heated by the devices 28, 29, and 30, and joins the dry air that flows through the air guide passage 9 via the second vent 42. , the temperature of the dry air blown out from the outlet 11 is higher than the temperature at the inlet 10 . The dry air supplied from the blower fan 3 is introduced as positive pressure dry air from the rear opening 58 into the interior of the air guide wall 46 to cool the halogen lamp 28, the reflector 29, and the filter 30. 2, the air may flow out of the reflector 29 from the vent 42 .

When the dry air flows out from the second ventilation port 42 , part of the light emitted from the halogen lamp 28 leaks out from the second ventilation port 42 . In this way, in order to prevent the light leaking from the second vent 42 from being radiated from the outlet 11 and making the user feel dazzled when drying the hair, the outer surface of the second vent 42 is provided with the second An anti-glare structure is provided to redirect and guide the light leaked from the vent 42 away from the outlet 11.例文帳に追加In FIG. 12, the antiglare structure includes a cylindrical antiglare body 75 covering the outer surface of the opening of the second vent 42 , and the surrounding wall 62 described above also serves as the antiglare body 75 .

As described above, when the outer surface of the opening of the second vent 42 is covered with the anti-glare body 75, the ventilation passage 76 for allowing dry air to pass through is formed between the anti-glare body 75 and the second vent 42. 42 is formed in a lying L shape. Since the front end of the ventilation passage 76 is blocked by the passage end wall 77 which abuts from the front reflector 37 and abuts against the inner surface of the antiglare body 75, the dry air flowing into the ventilation passage 76 is reversed backward. Moving. Further, the dry air flowing out from the ventilation passage 76 reversely moves along the rear end of the passage end wall 77 and merges with the dry air flowing in the air guide passage 9 . In order to smoothly reverse the movement of the dry air, a rear reversing guide surface 78 for guiding the dry air backward is formed at the inner corner sandwiched between the antiglare body 75 and the passage end wall 77. A front reversing guide surface 79 for reversing and guiding the drying air forward is formed at the rear end of 75 (see FIG. 12). The rear reversing guide surface 78 is a quadrant circular arc surface continuous with the passage end wall 77, and the front reversing guide surface 79 is a semicircular arc surface.

In the hair dryer provided with the antiglare body 75 as described above, while the dry air introduced into the reflector 29 cools the halogen lamp 28, the reflector 29, and the filter 30, the dry air leaks out from the second vent 42 together with the dry air. The anti-glare body 75 shields the light, thereby preventing the light from being radiated along the air guide passage 9 toward the air outlet 11 side. For example, the light leaked from the second vent 42 is reflected by the anti-glare body 75 toward the side of the second vent 42, or scattered by the anti-glare body 75, and then absorbed and attenuated by the anti-glare body 75. can be made Therefore, it is possible to reliably prevent the light leaking out of the reflector 29 from being radiated from the outlet 11, and to provide a dryer which does not make the user feel glare when drying the hair.

A sustained release ring (functional ingredient emitter) 80 formed in a ring shape is arranged in the air guide passage 9 . The sustained release ring 80 is composed of an open-pore ceramic porous body formed by sintering fine ceramic powder. As shown in FIG. 82 and a group of radiating walls 83 provided between both rings 81 and 82 integrally. A portion surrounded by the inner and outer rings 81 and 82 and the radial wall 83 is a group of ventilation openings (ventilation section) 84 that allows passage of dry air from the upstream side to the downstream side. The continuous pore portion of the sustained release ring 80 is impregnated with a cosmetic liquid (functional liquid) containing at least one cosmetic ingredient (functional ingredient) having cosmetic functions such as vitamins, hyaluronic acid and collagen. ing. By exposing the sustained-release ring 80 to dry air, the cosmetic liquid is gradually vaporized, and the cosmetic component (vaporized cosmetic liquid) is gradually released. The released beauty ingredients are delivered to the hair and scalp on dry air.

The air passage 9 is provided with a speed-increasing air passage 85, which is an area configured so that the air passage flow velocity is higher than that of other air passage areas in the air passage 9, downstream of the blower fan 3. ing. Specifically, the airflow velocity in the speed-increasing airflow path 85 is configured to be higher than the airflow velocity in the air outlet 11. It functions as a fast air passage 85 . The annular wind tunnel-shaped speed-increasing air passage 85 (annular air passage 35) is upstream of the air passage 9 due to the outer surface shape of the reflector 29 (heat source unit 4A) and the inner surface shape of the air guide tube 7 (main body case 1). It is formed so as to narrow from the side to the downstream side. The aforementioned sustained release ring 80 is disposed in a state in which it faces an enlarged recessed portion 37c provided in a circular fashion on the front reflector 37 in the speed increasing air passage 85 (annular air passage 35).

As described above, since the sustained-release ring 80 is arranged in the annular air passage 35 functioning as the speed-increasing air passage 85, the sustained-release ring 80 is exposed to the dry air having a high flow velocity, and the cosmetic impregnated in the ring 80 is The liquid can be vaporized efficiently. In addition, since the air passage cross-sectional area of the speed-enhancing air passage 85 is further reduced by the sustained release ring 80, the air passage flow velocity at the position where the sustained release ring 80 is arranged is further increased, and the cosmetic impregnated in the ring 80 is further increased. The liquid can be vaporized more efficiently.
According to the speed increasing air passage 85 formed by the outer surface shape of the reflector 29 and the inner surface shape of the air guide tube 7 and narrowing from the upstream side to the downstream side of the air guide passage 9, the structure inside the air guide passage 9 is changed. It is possible to gradually increase the speed of the drying air in the entire speed increasing air passage 85 while suppressing the pressure loss while simplifying.

Since the sustained release ring 80 is arranged around the reflector 29 (the heat source unit 4A) (annular air passage 35), the sustained release ring 80 is warmed by the heat of the reflector 29, and the cosmetic liquid impregnated in the ring 80 is released. more efficient vaporization. Further, according to the sustained release ring 80 arranged in the annular air passage 35, the ring 80 is not directly exposed to the light of the halogen lamp 28 irradiated from the front of the heat source unit 4A. The sustained release ring 80 is not heated, and it is possible to prevent the cosmetic liquid from being vaporized more than necessary.
Since the heat source unit 4A also serves as a member forming the speed increasing air passage 85, the structure of the dryer can be simplified.

The annular air passage 35 functioning as the speed-increasing air passage 85 is originally formed with a small air passage cross-sectional area. , it is inevitable that the cross-sectional area of the air passage becomes smaller and the ventilation resistance increases. Therefore, in this embodiment, by arranging the sustained release ring 80 in a state facing the expanded recessed portion 37c of the front reflector 37, the cross-sectional area of the air passage at the arrangement position of the sustained release ring 80 becomes smaller than necessary. is relieved by the expansion concave portion 37c, an increase in ventilation resistance caused by the sustained release ring 80 can be avoided, and a decrease in force of the dry air blown out from the blower port 11 can be prevented. In addition, since more heat is radiated from the outer surface of the reflector 29 enlarged by the expansion concave portion 37c, the sustained release ring 80 can be effectively warmed and the vaporization of the functional liquid can be further accelerated.

The ring-shaped sustained-release ring 80 can have a larger surface area than a cylindrical functional-ingredient release body having the same volume. In addition, by providing the sustained release ring 80 in the speed increasing air passage 85 formed in the shape of an annular wind tunnel, it is possible to increase the contact opportunity between the sustained release ring 80 and the drying air flowing through the speed increasing air passage 85. Beauty ingredients can be accurately released against the wind.
In addition, if the ring-shaped sustained release ring 80 is formed with a ventilation opening 84 along the direction of the dry air generated by the blower fan 3, the opportunity for contact between the sustained release ring 80 and the dry air flowing through the speed increasing air passage 85 is increased. It can be increased more, and a sufficient amount of cosmetic ingredients can be released to the dry air.

The unit support frame 66, the sustained release ring 80, and the spring receiving frame 64 are respectively provided at three front and rear clamping portions 86 and middle clamping portions on the facing surfaces of the half bodies 7a and 7b of the wind guide tube 7. 87 and a rear clamping portion 88 are firmly clamped and fixed. The sustained release ring 80 is fixed with a slight gap between it and the inner surface of the wind guide tube 7 , and substantially the entire surface of the sustained release ring 80 is exposed to the dry air flowing through the accelerating air passage 85 . be done.

In addition to the above forms, the sustained release ring 80 has a form composed of either an inner ring 81 or an outer ring (ring portion) 82 and a plurality of radial walls 83, or a ring portion with the radial walls 83 omitted. Only 82 forms can be taken. In the case of the former form, for example, the sustained release ring 80 includes a ring portion 82 in which the inner ring 81 is omitted and the thickness is increased, and a plurality of radial walls 83 projecting inward from the ring portion 82. can be prepared. In addition, the sustained release ring 80 includes a ring portion 82 and a plurality of radial walls 83 projecting outward from the ring portion 82, or the ring portion 82 and the ring portion 82 facing outward and inward. A plurality of radiating walls 83 protruding therefrom may also be provided.

Further, the sustained release ring 80 does not need to be formed in one continuous ring shape, and the sustained release ring 80 can be formed by connecting a plurality of arc-shaped members in a ring shape. For example, the sustained release ring 80 of each of the above forms can be divided into two semicircular segments. According to the sustained release ring 80, the wind guide tube 7 can be joined after each of the divided bodies 7a and 7b is attached to the intermediate holding portion 87 of the half-divided bodies 7a and 7b, thereby improving the ease of assembly of the hair dryer. Alternatively, the sandwiching portion 87 between the half bodies 7a and 7b may be omitted, and the sustained release ring 80 may be supported and fixed by an adhesive body such as double-sided tape adhered to the inner surfaces of the half bodies 7a and 7b of the wind tunnel tube 7. can also The sustained release ring 80 can also be composed of three or more arcuate segments. In this way, when the sustained release ring 80 is composed of a plurality of divided bodies, the ends of the adjacent divided bodies may be arranged so as to be in close contact with each other, or may be arranged with a gap therebetween.

An ion release structure is provided inside the wind guide tube 7 facing the blowout port 11 in order to carry negative ions on the dry air in addition to the beauty ingredients and deliver them to the hair and scalp. The ion emitting structure comprises an electrode holder 91 , three central electrodes 92 supported by the electrode holders 91 , and a peripheral electrode 94 fixed to a cylindrical wall 93 surrounding the central electrode 92 . The electrode holder 91 is clamped and fixed by a pair of clamping walls 95 provided on the wind guide tube 7 . The auxiliary blowing case 6 is formed with a vent 96 for sending out infrared light and dry air, and an ion vent 97 is formed in the center of the lower part of the case facing the central electrode 92 . In FIG. 3, a thermal fuse 98 is arranged on the upper wall portion of the wind guide tube 7 on the front side of the heat source unit 4A.

The present embodiment differs from the first embodiment in the configuration of the internal structure arranged in the air guide passage 9 and the like. More specifically, the reflector 29 has a bowl-like shape whose diameter increases toward the front, and the inner surface of the reflector 29 serves as a first reflecting surface 39. The reflector 29 is inserted into and fixed to a boss portion 101 of a disk-shaped socket 34. ing. The reflector 29, the socket 34, the fan motor 2, and the like are supported and fixed by a support frame 102 arranged and fixed in a cross shape on the air guide passage 9. As shown in FIG. A bulb 31 of the halogen lamp 28 is formed in an ellipsoidal shape. The filter 30 is supported by a retaining ring 103 composed of a pair of halves, and the retaining ring 103 is supported and fixed by the support frame 102 and the sustained release ring 80 so as to be in close contact with the front end of the reflector 29. ing. The retaining ring 103 constitutes a part of the reflector 29, and the halogen lamp 28, the reflector 29, the socket 34 and the retaining ring 103 constitute the heat source unit 4A of this embodiment. The main body case 1 is composed only of the wind guide tube 7 without the exterior tube 8. - 特許庁

Annular air passage 35 functioning as speed-increasing air passage 85 is formed by reflector 29, holding ring 103 (heat source unit 4A), and air guide tube 7 to form an annular wind tunnel that tapers toward the end. The sustained release ring 80 is arranged to face the outer surface of the front end of the retaining ring 103, and is composed of a ring portion 82 and 12 radial walls 83 projecting inward from the ring portion 82. . The ventilation opening 84 is formed so as to be surrounded by the ring portion 82 and the adjacent radiation walls 83 . Since other parts are the same as those of the first embodiment, the same reference numerals are given to the same members, and the description thereof will be omitted. The same applies to the following examples.

As described above, since the sustained-release ring 80 is arranged in the annular air passage 35 functioning as the speed-increasing air passage 85, the sustained-release ring 80 is exposed to the dry air having a high flow velocity, and the cosmetic impregnated in the ring 80 is The liquid can be vaporized efficiently. In addition, since the air passage cross-sectional area of the speed-enhancing air passage 85 is further reduced by the sustained release ring 80, the air passage flow velocity at the position where the sustained release ring 80 is arranged is further increased, and the cosmetic impregnated in the ring 80 is further increased. The liquid can be vaporized more efficiently.
Since the sustained release ring 80 is disposed in the portion of the speed-increasing air passage 85 that is tapered toward the front end of the heat source unit 4A where the air passage velocity increases, the vaporization of the cosmetic liquid can be further accelerated. .
Moreover, according to such a dryer, the reflector 29 is simplified into a bowl shape that is easy to form, and the heat source unit 4A is supported by the support frame 102, so that the structure inside the air guide passage 9 can be simplified.

(Example 3) Figs. 15 and 16 show Example 3 in which the dryer according to the present invention is applied to a hair dryer. In this embodiment, the halogen lamp luminous body 28 of the second embodiment is replaced with an infrared lamp that emits red light, and the filter 30 is omitted accordingly. A front end of the reflector 29 extends toward the outlet 11 in a cylindrical shape. The annular air passage 35 functioning as the speed-increasing air passage 85 is formed by the reflector 29 (the heat source unit 4A) and the air guide tube 7 in a tapered annular wind tunnel shape. The sustained release ring 80 is arranged to face the outer surface of the front end of the reflector 29. As in the first embodiment, the inner and outer rings 81 and 82 and a group of radial walls provided between the rings 81 and 82 are provided. 83 are integrally provided. A front end of the reflector 29 is supported and fixed by a sustained release ring 80 .

As described above, since the sustained-release ring 80 is arranged in the annular air passage 35 functioning as the speed-increasing air passage 85, the sustained-release ring 80 is exposed to the dry air having a high flow velocity, and the cosmetic impregnated in the ring 80 is The liquid can be vaporized efficiently. In addition, since the air passage cross-sectional area of the speed-enhancing air passage 85 is further reduced by the sustained release ring 80, the air passage flow velocity at the position where the sustained release ring 80 is arranged is further increased, and the cosmetic impregnated in the ring 80 is further increased. The liquid can be vaporized more efficiently.
Since the sustained release ring 80 is disposed in the portion of the speed-increasing air passage 85 that is tapered toward the front end of the heat source unit 4A where the air passage velocity increases, the vaporization of the cosmetic liquid can be further accelerated. .
In addition, the light emitter 28 is not limited to a halogen lamp, and may be an infrared lamp. By using a light emitter 28 with low emission luminance such as an infrared lamp, the filter 30 can be omitted, and the structure inside the air guide passage 9 can be reduced. can be simplified.

(Example 4) Figs. 17 and 18 show Example 4 in which the dryer according to the present invention is applied to a hair dryer. In this embodiment, the infrared lamp illuminant 28 of Embodiment 3 is replaced with a ring-shaped ceramic heater that emits infrared rays. ing. The functional ingredient ejector 80 is composed of a plurality of sustained release blocks 106 formed in a block shape. It is formed in the shape of an intermittent ring. The ventilating portion 84 of this embodiment is configured as the ventilating portion 84 in the area between the adjacent sustained release blocks 106 . Each sustained release block 106 is supported and fixed by fixing ribs 107 formed on the outer surface of the reflector 29 and the inner surface of the wind guide tube 7 . In this way, the functional ingredient releasing body 80 can also be formed in an intermittent ring shape by comprising a plurality of sustained release blocks 106, and the endless ring shaped functional ingredient releasing body (sustained release ring) 80 of each of the above embodiments relatively easy to form.

As described above, since a group of sustained release blocks 106 (functional ingredient emitters 80) are arranged in the annular air passage 35 functioning as the speed increasing air passage 85, the sustained release blocks 106 are exposed to the fast-flowing dry air. , the cosmetic liquid impregnated in the same block 80 can be efficiently vaporized. In addition, since the air passage cross-sectional area of the speed increasing air passage 85 is further reduced by the sustained release block 106, the flow velocity of the air passage at the position where the sustained release block 106 is arranged is further increased, and the cosmetic impregnated in the same block 106 is used. The liquid can be vaporized more efficiently.
A group of sustained-release blocks 106 are arranged in the part facing the front and rear halfway part of the reflector 29 where the flow velocity of the air passage is larger than that of the upstream end of the air passage in the speed-increasing air passage 85 having a tapered shape. vaporization can be further accelerated.
Since the brightness of the visible light emitted by the ceramic heater 28 is low, the internal structure of the air guide passage 9 can be simplified in that the filter 30 can be omitted, and the user feels glare when drying the hair. It can be done with a hair dryer.

(Example 5) Figs. 19 and 20 show Example 5 in which the dryer according to the present invention is applied to a hair dryer. In this embodiment, the support frame 102 of the second embodiment is formed of an open-pore ceramic porous body, and the support frame 102 is configured as the functional ingredient emitter 80 . The support frame 102 is provided in the air guide passage 9 from the outlet portion of the blower fan 3 to the third grill 25 . Each support frame 102 is supported and fixed by fixing ribs 107 formed on the outer surface of the retaining ring 103 and the inner surface of the wind guide tube 7 . As in this embodiment, when the heat source unit 4A including the reflector 29, the halogen lamp 28 and the socket 34 is supported by the support frame 102 which also serves as the functional component emitter 80, the halogen lamp (light emitting body) 28, the reflector 29 and the like are guided. By omitting a dedicated support structure for supporting inside the passage 9, the structure inside the air guide passage 9 can be simplified. Further, since the fan motor 2 for rotating the blower fan 3 is also supported by the functional component emitting body 80 which also serves as the support frame 102, a dedicated support structure for supporting the fan motor 2 in the air guide passage 9 is omitted. , the structure inside the air guide passage 9 can be further simplified. In this embodiment, the air flow space in the area where the support frame 102 is provided in the front-to-rear direction of the air guide tube 9 serves as the ventilation section 84 .

As described above, since the support frame 102 constituting the functional ingredient ejector 80 is arranged from the exit portion of the blower fan 3 to the annular air passage 35 functioning as the speed-enhancing air passage 85, the functional ingredient discharger 80 is provided for the fast drying air. By exposing the emitter 80, the cosmetic liquid impregnated in the emitter 80 can be efficiently vaporized. In addition, since the air passage cross-sectional area of the accelerating air passage 85 is further reduced by the functional ingredient ejector 80, the flow velocity of the air passage at the position where the functional ingredient ejector 80 is arranged is further increased, and the ejector 80 is impregnated. The applied cosmetic liquid can be vaporized more efficiently.
Since the functional ingredient emitter 80 is arranged over substantially the entirety of the air guide passage 9 on the downstream side of the blower fan 3, the vaporization of the cosmetic liquid can be further accelerated.

(Example 6) Fig. 21 shows Example 6 in which the dryer according to the present invention is applied to a hair dryer. This embodiment differs from the second embodiment in the structure of the light emitter 28 and the reflector 29 . A light emitter 28 made of a halogen lamp is replaced with a ring-shaped ceramic heater that emits infrared rays, and the ceramic heater 28 is connected to a socket 34 supported by a support frame 102 above the air guide passage 9 . The reflector 29 is integrally formed with a bowl-shaped outer reflector 110 and a funnel-shaped inner reflector 111 arranged inside and outside, and a ceramic heater 28 is arranged so as to face the first reflecting surface on the inner surface thereof. ing. A portion of the air guide passage 9 near the outlet 11 is closed except for the inner side of the inner peripheral wall 112 of the inner reflector 111, and a speed increasing air passage 85 is formed inside the inner peripheral wall 112, A functional ingredient releasing body 80 consisting of a ring portion 82 is arranged so as to fit inside the inner peripheral wall 112 . In this way, when the speed-enhancing air passage 85 is formed by the inner peripheral wall 112 of the inner reflector 111, the diameter of the air guide passage 9 is narrowed to converge the dry air blown out from the outlet 11, thereby increasing the directivity of the dry air. can be improved.

(Example 7) Fig. 22 shows Example 7 in which the dryer according to the present invention is applied to a hair dryer. This embodiment differs from the second embodiment in the configuration of the functional ingredient emitter 80 . The functional ingredient ejector 80 is composed of a ring-shaped speed-enhancing ring 115. The speed-enhancing ring 115 is formed in a cylindrical shape with a ring wall having a constant thickness dimension and tapered toward the tip. The inner peripheral surface narrows from the upstream side to the downstream side of the air passage 9 . In addition, the inner peripheral surface is formed in an inwardly convex curved shape. The speed-increasing ring 115 is provided concentrically so as to overlap the rear side of the reflector 29 in the air guide passage 9 downstream of the blower fan 3, and the outer peripheral surface of the rear edge of the ring 115 It is in close contact with the inner surface of the guide tube 7 . Further, the speed increasing ring 115 is supported by a support frame 102, and the support frame 102 has a cutout portion for supporting the speed increasing ring 115. As shown in FIG. A speed increasing air passage 85 is formed by the speed increasing ring 115 and the reflector 29 , and the functional ingredient emitter 80 faces the speed increasing air passage 85 .

Decrease the cross-sectional area of the air passage to increase the flow velocity of the dry air.

As described above, by arranging the speed-increasing structure 4B (air-passage internal structure 4) for positively increasing the speed of the dry air that reduces the cross-sectional area of the air passage 9, the speed-increasing air passage 85 is formed, the speed-increasing air passage 85 is formed by the speed-increasing structure 4B made of a dedicated member for speeding up the drying air. The flow rate can be set appropriately so that the functional liquid containing the beauty ingredients impregnated in the body is vaporized most efficiently. Further, since the speed-increasing air passage 85 can be formed only by arranging the speed-increasing structure 4B in the air guide passage 9, the structure of the dryer can be simplified.
Further, if the speed-increasing structure 4B is provided in the air guide passage 9 on the downstream side of the blower fan 3, and the speed-increasing structure 4B is configured by the speed-increasing ring 115, the dry air passing through the speed-increasing ring 115 is It is possible to increase speed while suppressing pressure loss with a simple configuration.

In addition, since the air passage cross-sectional area of the speed increasing air passage 85 is further reduced by the speed increasing ring 115, the flow speed of the air passage at the position where the speed increasing ring 115 is arranged is further increased, and the cosmetic impregnated in the speed increasing ring 115 is increased. The liquid can be vaporized more efficiently.
Since the speed increasing ring 115 is arranged in the portion of the speed increasing air passage 85 that is tapered toward the upstream half of the reflector 29, the air flow velocity on the upstream side of the speed increasing air passage 85 is increased. can further accelerate the vaporization of the cosmetic liquid.

(Embodiment 8) Fig. 23 shows Embodiment 7 in which the dryer according to the present invention is applied to a hair dryer. In this embodiment, the arrangement position of the speed increasing ring 115 is different from that in the seventh embodiment.

As a result, the flow velocity of the dry air generated by the blower fan 3 can be increased and the straightness of the dry air blown out from the outlet 11 can be improved as compared with the case where the speed increasing ring 115 is not provided. In addition, the noise generated during the pressure feeding by the blower fan 3 can be reduced.

The outer peripheral surface of the sustained release ring 80 is in close contact with the inner surface of the wind guide tube 7, and the dry air that has passed through the reflector 29 is guided by the rear end surface of the sustained release ring 80, and the reflector 29 and the sustained release ring 80 are guided. passes through the opening 118 through the gap between the The opening 118 forms a speed increasing air passage 85 of this embodiment, and the sustained release ring (functional ingredient emitter) 80 faces the speed increasing air passage 85 . In the present embodiment, the drying air is caused to collide with the sustained release ring 80 and is guided in a different direction, so that the chances of contact between the dry air and the sustained release ring 80 are increased, and the functional liquid containing the cosmetic ingredients is efficiently vaporized. can be done. Further, as in the sixth embodiment, the diameter of the air guide passage 9 is narrowed to converge the dry air blown out from the outlet 11, thereby improving the directivity of the dry air.

(Example 10) Figs. 25 and 26 show Example 10 in which the dryer according to the present invention is applied to a hair dryer. In this embodiment, the configuration of the heat source unit 4A is different from that in the second embodiment, and the heat source unit 4A is composed of a halogen lamp 28, a reflector 29, a filter 30, a socket 34, and a pair of half-split bodies that accommodate the members mentioned above. and an inner case 121 configured.

The functional liquid can be vaporized more efficiently. In addition, since the speed of the dry air passing through the ventilation section 84 can be gradually increased while suppressing the pressure loss, the flow velocity of the dry air blown out from the outlet 11 becomes smaller due to the pressure loss in the ventilation section 84. can be suppressed.

In this example, as in the eleventh example, the configuration of the functional ingredient emitter 80 is different from that in the tenth example. The functional ingredient emitting body 80 is formed in a cylindrical shape in which the wall thickness on the upstream side of the air guide passage 9 is smaller than the wall thickness on the downstream side of the air guide passage 9, and the inner peripheral surface thereof is a tapered surface. The outer peripheral surface is in close contact with the inner surface of the air guide tube 7 . A ventilation section 84 is formed along the direction of the dry air generated by the blower fan 3 between the functional ingredient ejector 80 and the inner circumferential surface of the annular air passage 35 . The ventilation section 84 is composed of a narrowed constricted air passage 132 that is formed in a circular shape in the annular air passage 35 . The inner case 121 is supported by support ribs 133 radially provided at four points on the inner surface of the functional ingredient emitter 80 .

Thus, the annular air passage 35 does not need to be formed in a tapered shape, and the air passage cross-sectional area of the air guide passage 9 is reduced by the heating unit 4A to increase the air passage flow velocity higher than that of the air outlet 11 portion. An annular air passage 35 that functions as a fast air passage 85 may be formed. As a result, it is possible to increase the chances of contact between the functional ingredient ejector 80 and the fast-flowing dry air, and to accurately release the cosmetic ingredients to the dry air.

A duckbill valve 144 is attached to the liquid supply port 141 to prevent the cosmetic liquid from leaking during replenishment.

According to the above configuration, the annular air passage 35 is formed between the outer surface of the support case 138 and the inner surface of the air guide tube 7 by utilizing the structure of the support case 138 and the air guide tube 7 (main body case 1). can be formed, the structure inside the air guide passage 9 can be simplified.

Since the blower fan 3 for generating the dry air directed from the air inlet 10 to the air outlet 11 is provided, all the air sucked from the air inlet 10 is blown out from the air outlet 11, so that the dry air is hard to disperse into one convergent air. It can be delivered as a stream to an object to be dried. In addition, in each of the above-described embodiments, the functional ingredient release body (sustained release ring) 80 (speed increasing Since the ring 115) is provided, the cosmetic liquid vaporized by exposing the emitter 80 to the dry air can be included in the dry air, which is difficult to disperse. Therefore, it is possible to accurately deliver the cosmetic component to the object to be dried on the dry air blown out from the outlet.

In addition, since the functional ingredient emitter 80 is arranged in the annular air passage 35 functioning as the speed increasing air passage 85, the functional ingredient emitter 80 (the speed increasing ring 115) is exposed to the fast drying air, The cosmetic liquid impregnated in 80 can be efficiently vaporized, and the cosmetic component can be sufficiently released to the dry air.

According to the above-mentioned dryer, the object to be dried is heated by the infrared rays contained in the light emitted by the luminous body 28, and the drying is accelerated. It consumes less power per unit time than a hair dryer that heats an object to accelerate drying. In addition, the functional component emitter 80 is warmed by the heat radiated from the outer surface of the reflector 29 heated by the light emitter 28, and the functional liquid is produced by exposing the emitter 80 to the drying air of the air guide passage 9. vaporization can be accelerated, and the functional ingredient can be sufficiently released to dry air. This makes it possible to obtain a dryer capable of delivering a large amount of functional ingredients on one converging stream of drying air directed toward an object to be dried. In addition, it is preferable that the functional ingredient emitter 80 is arranged in a state that it does not come into contact with the outer surface of the reflector 29 . This is because if the functional component emitter 80 is in contact with the outer surface of the reflector 29, the emitter 80 is heated more than necessary and the functional liquid is wastefully vaporized.
