Thus, the heat source unit 4 A and the air guide tube 7 form an annular air passage 35 having an annular air tunnel shape. When the halogen lamp 28 is turned on, visible light and infrared light are emitted from the bulb 31. The filter 30 is configured to transmit infrared light but prevent transmission of visible light, so that the user does not feel the glare of the halogen lamp 28. Note that blocking the transmission of visible light does not mean completely blocking visible light, but is a concept that includes attenuating visible light. Of course, it also includes those that can completely block visible light and transmit only infrared light.

Reflector 29 is formed by joining front reflector 37 and rear reflector 38. The front reflector 37 is configured by joining a pair of

half bodies

37a and 37b divided into right and left parts (see FIG. 7). The

half bodies

37a and 37b are made of a molded product obtained by press-molding a metal such as aluminum, and the inner surfaces thereof are polished to a mirror surface to form reflection surfaces. On the inner surface of the front reflector 37, a first reflection surface 39 for guiding the light radiated from the halogen lamp 28 forward toward the filter 30 (the outlet 11 side) is provided, and the light radiated from the halogen lamp 28 is directed rearward. And a second reflecting surface 40 for guiding reflection is provided, and the second reflecting surface 40 is formed adjacent to the first reflecting surface 39. The inner surfaces of the

half bodies

A filter seat 41 is formed on the inner surface of the front end of each of the

half bodies

37a and 37b, and two second ventilation holes 42 are formed on the rear peripheral surface of the filter seat 41. The second ventilation port 42 is formed as a slit-shaped opening formed substantially all around the wall near the front end of the front reflector 37 when the pair of

half bodies

37a and 37b are assembled. Although the above-mentioned front reflector 37 is constituted by a pair of

half bodies

37a and 37b, the front reflector 37 may be constituted by one deformed cylindrical body. In this case, the front reflector 37 is formed by a die-cast molded product made of a metal such as aluminum.

The rear reflector 38 is formed of a die-cast molded product made of aluminum. The front reflector 38 receives the light radiated from the halogen lamp 28 and the light reflected and guided by the second reflection surface 40 on the front surface thereof, and transmits the light to the filter 30 (the outlet 11 side). ) Is provided with a concave mirror-shaped third reflecting surface 43 for guiding reflection toward the front, and its inner surface is polished to be a mirror-shaped reflecting surface. The third reflecting surface 43 may be a mirror-like reflecting surface by plating.

光源 A light source support structure for supporting the halogen lamp 28 is provided behind the third reflection surface 43. The light source support structure includes a light source base 45 composed of four bosses for supporting the halogen lamp 28, and a hexagonal tubular air guide wall 46 surrounding the light source base 45. Are fixed to each light source base 45 with four screws 47 together with the wiring board 49. At the center of the third reflection surface 43, a first ventilation port 48 for introducing dry air into the interior of the reflector 29 is formed. A light source cooling passage is provided between the air guide wall 46 and the halogen lamp 28 and communicates with the first ventilation port 48. The wiring board 49 collects leads for supplying power to the halogen lamp 28 from the inside of the grip 12 to the inside of the air guide tube 7 and leads for supplying power to the fan motor 2, and distributes the leads from there. It is arranged in. Further, the wiring board 49 functions as a light shielding plate for preventing light leaked from the first ventilation port 48 from being emitted to the suction port 10 side.

The front reflector 37 and the rear reflector 38 are joined and fastened and fixed in a state where the second reflection surface 40 and the third reflection surface 43 are adjacent to each other. In order to fasten and fix the

reflectors

37 and 38, a front engaging portion (projection) 51 is formed in the rear edge 57 of the

half body

37a and 37b so as to protrude radially in a bent state. At the front end of the rear reflector 38, 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. A recessed rear engagement portion 54 and a screw boss 55 formed by notching the joining wall 53 are formed at two opposing portions of the wall 53. The front reflector 37 and the rear reflector 38 can be joined by joining the pair of

half bodies

37a and 37b and engaging the front engagement portion 51 and the rear engagement portion 54 with each other. The front reflector 37 and the rear reflector 38 can be integrated by screwing the screw 56 inserted into the through hole 51a of the front engagement portion 51 into the screw boss 55. 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 reflection surface 40 and the third reflection 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 of the rear edge 57 of the front reflector 37 and the joining groove 52, and furthermore, the front reflector 37 and the rear By the engagement of the engagement portion 54, the rotation about the central axis P is prevented. In addition, the front engagement part 51 can also be comprised by the protrusion formed in the radial direction from the rear edge of the

half bodies

37a and 37b. Further, the front reflector 37 may be constituted by one reflecting cylinder. In that case, it can be constituted by a die-cast molded product made of a metal such as aluminum. Further, the front engagement portion 51, the rear engagement portion 54, and the screw 56 need not be provided at two opposing positions, and can be formed at only one position. The front reflector 37 may be configured by joining three or more divided bodies.

The filter 30 is made of low expansion glass, and is fixed to the front end of the front reflector 37 by a filter support structure. The filter support structure includes a filter seat 41 formed on the front reflector 37, and a press ring 60 for holding and fixing the filter 30 back and forth in cooperation with the filter seat 41. The press ring 60 includes an end wall 61 that presses and holds the front peripheral edge of the filter 30 and a ring-shaped circling wall 62 that fits over the outer peripheral surface of the filter seat 41. It functions as the glare 75. As shown in FIG. 4, the holding ring 60 is fixed to the front reflector 37 with screws 63. The filter seat 41 is in close contact with the peripheral surface and the 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 vulnerable to impact, and the filament is broken or deformed when a large external force is applied. The heat source unit 4 A is floatingly supported on the main body case 1 in order to prevent an impact from acting on the halogen lamp 28. More specifically, as shown in FIG. 9, a hexagonal frame-shaped spring receiving frame 64 that supports the heat source unit 4A is fixed to the inner surface of the wind guide tube 7 that surrounds the periphery of the light source support structure, and the rear reflector 38 and the spring receiving frame 64 are fixed. At three locations on the facing surface, shock absorbing springs 65 that support the heat source unit 4A are arranged. Further, a hexagonal frame-shaped unit support frame 66 supporting the heat source unit 4A is fixed to the inner surface of the air guide tube 7 surrounding the periphery of the filter 30, and an antiglare body 75 described later and an opposing surface 3 of the unit support frame 66 are fixed. A viscoelastic gel-like elastic body 67 that supports the heat source unit 4A is disposed at each location.

The spring receiving frame 64 is formed by connecting three spring arms 70 formed of leaf springs in a hexagonal frame shape. A spring seat 71 for receiving one end of the shock absorbing spring 65 is provided at the center of each spring arm 70. Are 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 in a hexagonal frame shape by a leaf spring, and a gel holding portion 73 holding a gel-like elastic body 67 is formed at three places. 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 elastic body 67 absorbs the shock. By doing so, it is possible to prevent the impact on the halogen lamp 28 by absorbing and absorbing the impact. Therefore, even in the case where 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 impact is applied to the heat source unit 4A. Can be prevented from acting. Since the failure of the halogen lamp 28 due to an external impact or external vibration can be prevented well, the light emitting function of the halogen lamp 28 can be properly exhibited for a long time.

At the time of use, the halogen lamp 28 is turned on, the blower fan 3 is driven to irradiate the hair with the infrared light that has passed through the filter 30, and the dry air generated by the blower fan 3 is sent to the hair. Dry the hair. Part of the drying air is introduced from the rear opening 58 into the air guide wall 46, and flows into the first ventilation port 48 from the light source cooling passage to cool the halogen lamp 28, the reflector 29, and the filter 30 and then to the second The air flows out of the reflector 29 through the air vent 42, merges with the dry air flowing through the air guide path 9, and is sent out from the outlet 11. While a part of the drying air sent from the blowing fan 3 flows along the air guide path 9 (annular air path 35) around the heat source unit 4A, a negative pressure state is created around the second ventilation port 42. To Therefore, due to the Venturi effect, the air near the second ventilation port 42 inside the reflector 29 is attracted by the dry air and merges, and is sent to the outlet 11. The drying air that has cooled the halogen lamp 28, the reflector 29, and the filter 30 is heated by each of the

devices

28, 29, and 30 and merges with the drying air that flows through the air guide path 9 through the second ventilation port 42. The temperature of the drying air blown out from the outlet 11 is higher than the temperature at the inlet 10. The drying air supplied from the blowing fan 3 is introduced into the air guide wall 46 from the rear opening 58 as positive pressure drying air to cool the halogen lamp 28, the reflector 29, and the filter 30. 2 It may be made to flow out of the reflector 29 from the vent 42.

(4) When the drying air flows out of the second vent 42, a part of the light emitted from the halogen lamp 28 leaks out of the second vent 42. As described above, in order to prevent the light leaked from the second vent 42 from being emitted from the air outlet 11 and causing the user to feel dazzling when the hair is dry, the outer surface of the second vent 42 is An anti-glare structure is provided that guides light leaking from the vent 42 in a direction away from the outlet 11. In FIG. 12, the anti-glare structure includes a cylindrical anti-glare body 75 that covers the outer surface of the opening of the second ventilation port 42, and the above-described surrounding wall 62 also serves as the anti-glare body 75.

As described above, when the outer surface of the opening of the second ventilation port 42 is covered with the anti-glare body 75, the ventilation path 76 that allows the passage of the dry air is provided between the anti-glare body 75 and the second ventilation port 42. It is formed in a recumbent L-shape in a state continuous with 42. Since the front end of the ventilation passage 76 is closed by the passage end wall 77 which is in contact with the front reflector 37 and contacts the inner surface of the anti-glare body 75, the dry air flowing into the ventilation passage 76 reverses backward. Moving. Further, the drying air flowing out of the ventilation passage 76 reversely moves along the rear end of the passage end wall 77 and joins with the drying air flowing through the air guide passage 9. In order to smoothly perform the reversal movement of the drying wind, a rear reversing guide surface 78 for guiding the drying wind backward is formed in an inner corner portion sandwiched between the anti-glare body 75 and the passage end wall 77, and the anti-glare body is formed. A front reversing guide surface 79 for guiding reversal of the drying air forward is formed at the rear end of the rear surface 75 (see FIG. 12). The rear inversion guide surface 78 is formed of a quadrant arc surface that is continuous with the passage end wall 77, and the front inversion guide surface 79 is formed of a semicircular arc surface.

In the hair dryer provided with the above-described anti-glare body 75, while the halogen lamp 28, the reflector 29, and the filter 30 are cooled by the drying air introduced into the interior of the reflector 29, they leak out of the second ventilation port 42 together with the drying air. The light that is generated can be shielded by the anti-glare body 75 to prevent the light from being emitted toward the air outlet 11 along the air guide path 9. For example, light leaked from the second vent 42 is reflected by the anti-glare body 75 toward the second vent 42 or scattered by the anti-glare body 75, and further absorbed and attenuated by the anti-glare body 75. Can be done. Therefore, it is possible to reliably prevent the light leaking out of the reflector 29 from being emitted from the outlet 11, and to provide a dryer that does not make the user feel dazzling when the hair is dried.

徐 The air guide path 9 is provided with a sustained release ring (functional component release body) 80 formed in a ring shape. The sustained release ring 80 is made of a continuous-porous ceramic porous body formed by sintering ceramic fine powder, and as shown in FIG. 11, an inner ring 81 and an outer ring (ring portion). 82 and a group of radiating walls 83 provided between the

rings

81 and 82 are integrally provided. A portion surrounded by the inner and

outer rings

81 and 82 and the radiation wall 83 is a group of ventilation openings (venting portions) 84 that allow the 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 component among cosmetic components (functional components) 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 sent to the hair and scalp in a dry wind.

The wind guide path 9 is provided with a speed-increasing wind path 85 that is a region configured so that the flow speed of the air passage is larger on the downstream side of the blower fan 3 than in the other air passage regions in the wind guide passage 9. ing. Specifically, the air flow velocity in the speed-increasing air path 85 is configured to be larger than the air flow velocity in the outlet 11, and in the present embodiment, the annular air path 35 in the shape of an annular wind tunnel is increased. It functions as a fast wind path 85. The annular wind tunnel-shaped speed-increasing air path 85 (annular air path 35) is formed upstream of the air guide path 9 by the outer surface shape of the reflector 29 (heat source unit 4A) and the inner surface shape of the wind guide tube 7 (main body case 1). It is formed so as to be narrowed from the side to the downstream side. The slow release ring 80 is disposed in the speed increasing air passage 85 (annular air passage 35) so as to face the expanding concave portion 37c provided in the front reflector 37 in a circular shape.

As described above, since the sustained release ring 80 is disposed in the annular air passage 35 functioning as the speed-increasing air passage 85, the sustained release ring 80 is exposed to the dry wind having a high flow rate, and the beauty impregnated in the ring 80 is exposed. The liquid for use can be vaporized efficiently. In addition, since the cross-sectional area of the speed increasing air passage 85 is further reduced by the sustained release ring 80, the air flow velocity at the position where the sustained release ring 80 is disposed is further increased, and the beauty impregnated in the ring 80 is increased. The liquid for use can be more efficiently vaporized.
According to the speed increasing air passage 85 which is formed by the outer surface shape of the reflector 29 and the inner surface shape of the air guide tube 7 and narrows from the upstream side to the downstream side of the air guide passage 9, the structure in the air guide passage 9 is reduced. While simplifying, 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.

Since the sustained release ring 80 is disposed around the reflector 29 (heat source unit 4A) (annular air passage 35), the sustained release ring 80 is heated by the heat of the reflector 29, and the cosmetic liquid impregnated in the ring 80 is removed. It can be more efficiently vaporized. Further, according to the sustained release ring 80 provided 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. Since the sustained release ring 80 is not heated, 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 constituting the speed-up 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 cross-sectional area of the air passage, and when the sustained-release ring 80 is provided in the speed-increasing air passage 85, the portion where the ring 80 is provided Therefore, it is inevitable that the air passage cross-sectional area becomes smaller and the airflow resistance increases. Therefore, in the present embodiment, by arranging the sustained release ring 80 in a state directly facing the expanding concave portion 37c of the front reflector 37, the cross-sectional area of the air passage at the position where the sustained release ring 80 is disposed becomes unnecessarily small. Can be alleviated by the expanding concave portion 37c, so that an increase in airflow resistance due to the sustained release ring 80 can be avoided, and the momentum of the dry air blown out from the outlet 11 can be prevented from lowering. Further, since more heat is radiated from the outer surface of the reflector 29 enlarged by the expanding concave portion 37c, the sustained release ring 80 can be effectively warmed to further promote the vaporization of the functional liquid.

In the sustained release ring 80 formed in a ring shape, the surface area can be increased as compared with a columnar functional component 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, the chance of contact between the sustained release ring 80 and the drying air flowing through the speed-increasing air passage 85 can be increased, and The beauty ingredient can be accurately released to the wind.
In addition, when the ventilation opening 84 is formed in the ring-shaped sustained release ring 80 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. The amount can be further increased, and a sufficient amount of cosmetic ingredients can be released with respect to the dry wind.

The unit support frame 66, the sustained release ring 80, and the spring receiving frame 64 are respectively provided with three front clamping portions 86 provided before and after the opposing surfaces of the

half bodies

7a and 7b of the air guide cylinder 7, and a middle clamping portion. 87 and the rear holding portion 88 for firmly holding and fixing. The sustained release ring 80 is fixed with a slight gap provided between the sustained release ring 80 and the inner surface of the air guide tube 7, and substantially the entire surface of the sustained release ring 80 is exposed to dry wind flowing through the speed-increasing air passage 85. Is done.

In addition to the above-described configuration, the sustained-release ring 80 is configured to include one of the inner ring 81 and the outer ring (ring portion) 82 and a plurality of radiating walls 83, or the ring portion is formed by omitting the radiating wall 83. It is possible to take the form of only 82. In the case of the former form, for example, the sustained release ring 80 includes a ring portion 82 having an increased thickness by omitting the inner ring 81 and a plurality of radial walls 83 projecting inward from the ring portion 82. Can be provided. Further, 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, the outward direction and the inward direction from the ring portion 82. And a plurality of radiating walls 83 protruding therefrom.

徐 Moreover, the sustained release ring 80 does not need to be formed in one continuous ring shape, but may 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 arc-shaped divided bodies. According to such a sustained release ring 80, the wind guide tube 7 can be joined after each divided body is mounted on the middle holding portion 87 between the

half bodies

7a and 7b, so that the assemblability of the hair dryer can be improved. Also, the intermediate holding portion 87 of the

half bodies

7a and 7b is omitted, and the sustained release ring 80 is supported and fixed by an adhesive such as a double-sided tape adhered to the inner surfaces of the

half bodies

7a and 7b of the wind tunnel tube 7. Can also. In addition, the sustained release ring 80 may be formed of three or more arc-shaped divided bodies. As described above, when the sustained release ring 80 is constituted by 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.

(4) An ion emission structure is provided inside the air guide tube 7 facing the air outlet 11 in order to send negative ions in addition to the cosmetic ingredients to the hair and the scalp with the dry air. The ion emission structure includes an electrode holder 91, three central electrodes 92 supported by the electrode holder 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 cylinder 7. The auxiliary outlet case 6 has a through-hole 96 for sending out the infrared light and the drying air, and further has an ion through-hole 97 at the center of the lower part of the case facing the center electrode 92. In FIG. 3, a temperature fuse 98 is arranged on the upper wall portion of the wind guide cylinder 7 on the front side of the heat source unit 4A.

The sustained release ring 80 is disposed so as to face the front end outer surface of the holding ring 103, and includes a ring portion 82 and twelve radial walls 83 protruding 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.

The liquid for use can be vaporized efficiently. In addition, since the cross-sectional area of the speed increasing air passage 85 is further reduced by the sustained release ring 80, the air flow velocity at the position where the sustained release ring 80 is disposed is further increased, and the beauty impregnated in the ring 80 is increased. The liquid for use can be more efficiently vaporized.
In the constricted speed-up air passage 85, the sustained release ring 80 is disposed at a portion facing the front end of the heat source unit 4A where the air flow speed becomes larger, so that the vaporization of the cosmetic liquid can be further promoted. .
Further, according to such a dryer, since the reflector 29 is formed in a bowl shape which is easy to form by simplifying and the heat source unit 4A is supported by the support frame 102, the structure in the air guide passage 9 can be simplified.

(Embodiment 3) FIGS. 15 and 16 show Embodiment 3 in which the dryer according to the present invention is applied to a hair dryer. In the present embodiment, the luminous body 28 formed of the halogen lamp of the second embodiment is changed to an infrared lamp that emits red light, and the filter 30 is omitted accordingly. The front end of the reflector 29 is extended in a round tube shape toward the outlet 11. 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 wind guide tube 7 into a tapered annular wind tunnel shape. The sustained release ring 80 is disposed so as to face the outer surface of the front end of the reflector 29, and similarly to the first embodiment, the inner and

outer rings

The liquid for use can be more efficiently vaporized.
Since the sustained release ring 80 is provided at the portion facing the front end of the heat source unit 4A where the air flow velocity becomes larger in the constricted speed-up air passage 85, the vaporization of the cosmetic liquid can be further promoted. .
The luminous body 28 is not limited to the halogen lamp, but may be an infrared lamp. The use of the luminous body 28 having a low light emission luminance, such as an infrared lamp, allows the filter 30 to be omitted. Can be simplified.

(Embodiment 4) FIGS. 17 and 18 show Embodiment 4 in which the dryer according to the present invention is applied to a hair dryer. In the present embodiment, the luminous body 28 composed of the infrared lamp of the third embodiment is changed to a ring-shaped ceramic heater that emits infrared rays, and the reflector 29 is formed in a flat bowl shape and fixed to the front surface of the socket 34. ing.
