Detailed Description of the Invention 【Technical field】

The present invention relates to a hair dryer for winding hair and curling the hair.

[Background Art]

Various attachments such as brushes 10 that are planted on the tip of the dryer main body 3 that accommodates the heating element and the blower device in the blowing direction.
There are some 14 that can be attached and removed freely. For example, the one disclosed in Japanese Utility Model Publication No. 52-17090 is:
As shown in FIG. 15 and FIG. 16, a plurality of divided hair winding cylinders 6a are radially attached to the outer periphery of the support bar 5 protruding from the dryer main body 3, and both ends of the hair winding cylinder 6a are attached. The brush 10 is detachably fixed by the holding recess 15 and the holding cap 16, and the brush 10 is planted on the outer peripheral surface of the hair winding cylinder 6a.However, there is no hot air passage inside the hair winding cylinder 6a, and the dryer is used. Body 3
Hot air is blown from the hot air outlet 13 opened on the end face of the hair winding body 6a.
The structure is such that it is ejected along the outer periphery of. For this reason, the hair is wrapped around the outer periphery of the hair winding cylinder 6a, and the hot air jet 13
Even if hot air is blown from the hair winding drum 6a, it is parallel to the axial direction.
Since hot air is blown out only on the outer circumference of the
The hot air discharged from only hits the hair wound around the base end of the hair winding drum 6a, and it is difficult for the hot air to reach the hair at locations other than the base end of the hair winding drum 6a, such as drying or curling the hair. I could not expect much effect. Then, there is a device disclosed in Japanese Utility Model Publication No. Sho 57-3521 that allows hot air to be blown out from the inside of the hair winding drum. That is, as shown in FIG. 17 and FIG. 18, a hot air passage 8a is formed inside a hollow inner cylinder 5a protruding from the center of the end surface of the dryer body 3, and a slit-shaped opening 17 is opened in the inner cylinder 5a. , A cylindrical hair winding drum 6 is detachably fitted to the outer circumference of the inner cylinder 5a to form a hot air passage 8b between the outer circumference of the inner cylinder 5a and the inner circumference of the hair winding cylinder 6, and the dryer main body 3 The hot-air outlet 4 on the end face is exposed to the hot-air passage 8b, the hot-air blowing hole 9 is opened in the hair winding cylinder 6, and the brush 10 is planted. Then, the hot air supplied from the hot air passage 8a is ejected from the hot air blowing hole 9 through the slit-shaped opening 17, and the hot air supplied from the hot air outlet 4 is ejected from the hot air blowing hole 9 through the hot air passage 8b.
In this way, since the hot air passages 8a and 8b are formed in the inner cylinder 5a both inside and outside, the hair winding cylinder 6 becomes thicker,
There is a drawback that the hair cannot be wound small and the curling force is also reduced. Further, since the cylindrical hair-rolling drum 6 is supported only at both ends by the support protrusions 18 protruding from the base end and the tip of the inner barrel 5a, and is not supported at all in the middle portion, When the hair is wound around the outer circumference, the middle part of the hair winding drum 6 bends inward, the hot air passage 8b between the inner cylinder 5a and the hair winding drum 6 is easily blocked, and the hot air discharge efficiency is deteriorated, resulting in a drying performance. Also, there is a problem that the curling force is reduced.

[Object of the invention]

The present invention has been made in view of the above technical background, and an object thereof is to supply hot air from the hot air passage inside the hair winding cylinder to the entire hair wound around the hair winding cylinder. Another object of the present invention is to provide a hair dryer which is capable of forming a thin hair curling cylinder and preventing the hair curling cylinder with the hair wound therein from bending inward.

Further, on the outer periphery of the support rod 5, a plurality of relatively shallow supporting groove surfaces 36 and a relatively deep positioning groove 11 are provided along the axial direction. Here, the positioning groove 11
Has a rectangular groove shape, but the supporting concave groove surface 36 has a substantially arcuate cross section, and the supporting concave groove surface 36 is wider than the width of a supporting projection 39 formed at the tip of the supporting rib 7 described later. Also wide and support projection 39
The radius of curvature is larger than the radius of curvature of. A male screw portion 25 for screwing the screw hole 24 of the holding cap 16 is provided at the tip of the support rod 5. The hair winding cylinder 6 is formed in a cylindrical shape having a diameter substantially equal to the diameter of the ring 21, and is inserted into the outer periphery of the support rod 5 from which the holding cap 16 is removed, and the holding cap 16 is attached to the tip of the support rod 5. Both ends are held by a ring 21 and a holding cap 16. The conical portion of the retaining cap 16 has a flat knob portion 38 facing the conical portion.
Is provided so that the holding cap 16 can be easily twisted when the holding cap 16 is attached or detached. The hair-rolling drum 6 is formed of an elastic material (polyester elastomer PEE, etc.) into a cylindrical shape, and the inner surface of the hair-rolling drum 6 has a plurality of U-shaped sections as shown in FIGS. 5 and 7. The bag portion 26 is formed, and as shown in FIGS. 4 and 6, the bag portion 26 is provided with notches 27 at regular intervals. In this bag portion 26, a brush base portion 28 made of a material different from the elastic material (such as polybutylene terephthalate PBT) is enclosed every other line,

In addition, a bristle base 29 made of a material different from the elastic material (such as polybutylene terephthalate PBT) is included in the other bag portion 26, and the bristle 30 integrated with the bristle base 29 is the outer circumference of the hair winding cylinder 6. The supporting rib 7 is also formed by the bag portion 26 and the bristle base portion 29. Where brush base 28 and bristle base
29 and the bristle 30 are made of the same material, and are formed by two-color molding with the elastic material of the hair winding body 6 made of different materials,
Cylindrical holding bands 37 are formed on both ends of the hair winding drum 6.
In this way, the brush 10 and the bristle 30 are swingably (tilted) supported on the outer periphery of the hair winding drum 6 by the elasticity of the hair winding drum 6. Further, the tips of the support ribs 7 are formed in a substantially arcuate cross section and serve as support projections 39. The radius of curvature of the support projections 39 is smaller than that of the support groove surface 36 as described above. is there. The supporting projections 39 at the tips of the supporting ribs 7 are in contact with the supporting concave groove surfaces 36 on the outer peripheral surface of the supporting rod 5, so that the hair curling drum 6 interposes the supporting ribs 7 on the outer peripheral surface of the supporting rod 5. While the hair can be firmly wound around the hair winding drum 6, the support protrusion 39 smoothly moves along the concave curved surface of the support concave groove surface 36 in the width direction of the support concave groove surface 36. By being able to slide a little, the brush 10 and the bristle 30 are prone to fall down, and the curl can be smoothly performed without the hair being entangled with the brush 10 or the bristle 30. A hot air passage 8 is formed between the support ribs 7, and a plurality of hot air blowing holes 9 are formed in the hair winding cylinder 6 between the bristle 30 and the brush 10 so as to face the hot air passage 8.
Further, a supporting rib 7a slightly longer than the other supporting ribs 7 is projected on the inner peripheral surface of the hair winding cylinder 6.
By fitting 7a in the positioning groove 11 of the support rod 5, the hair winding drum 6 is prevented from rotating. Then, the hot air blown out from the hot air discharge port 4 passes through the hot air passage 8 and is blown out from the hot air blowing hole 9, blows the hot air from the inside of the hair wound on the hair winding cylinder 6, and the hot air blowout port The hot air blown from 13 is supplied to the hair from the outer peripheral side, the drying time of the hair can be shortened, and curling can be easily performed. FIG. 8 shows a second embodiment of the present invention, in which a plurality of supporting ribs 7 are formed on the inner peripheral side of the hair winding drum 6 by a bristle base 29 and a brush base 28 over substantially the entire length and supported. The rotation of the hair winding cylinder 6 is prevented by fitting the support projections 39 at the tips of the support ribs 7 into the support groove surface 36 that is provided in the outer periphery of the rod 5 along the axial direction. . FIG. 9 and FIG. 10 show a third embodiment of the present invention, in which a flat elastic sheet 12 as shown in FIG. The fitting portion 33 is provided over the entire length, and the elastic sheet 12 is wound into a cylindrical shape as shown in FIG. 10, and the male fitting portion 32 and the female fitting portion 33 on both sides are fitted and bonded to each other. A shape of a hair winding cylinder 6 having the same structure as that of the hair winding cylinder 6 of the first embodiment, which is formed in a cylindrical shape,

Cylindrical holding bands 37 made of the same material as the elastic sheet 12 are provided at both ends of the elastic sheet 12, and both ends of the elastic sheet 12 are thicker than other portions. By thus providing the cylindrical holding band 37, it is possible to hold the elastic sheet 12 in a cylindrical shape, protect the end portion which is weak in strength, and prevent the hair winding drum 6 from being damaged or cracked. FIG. 11 and FIG. 12 show an elastic sheet 12 for forming the hair winding cylinder 6 according to the fourth embodiment of the present invention. The elastic sheet 12 has a V groove in the middle between the brush 10 and the bristle 30.
Since the V groove 34 is formed, the elastic sheet 12 can be easily bent into a cylindrical shape, the brush 10 and the bristle 30 can easily fall, and the feeling is soft and the usability is improved. FIG. 13 and FIG. 14 show an elastic sheet 12 of a fifth embodiment of the present invention, in which an elastic sheet is provided between the brush base portion 28, the bristle base portion 29, the male fitting portion 32 and the female fitting portion 33. When the hair is wound around the hair winding cylinder 6 formed by winding the elastic sheet 12 to dry and curl the hair, the hair winding cylinder 6 Can be prevented from being deformed by receiving heat and force, and the durability is also improved.
