Abstract

PURPOSE:To ensure a proper fan blade size, prevent the release of a curled hair and enlarge a curling capacity by constituting a hair curl prevention frame in such a way as to have a cutout part in the peripheral walls of divided cylinders available from the division of a hair curler in a circumferential direction as a hair curl prevention means. CONSTITUTION:A hair curl prevention frame 12 has four linear hair curl frames 12 along an axial direction via the partial cutting of each peripheral toward a fan 6 as to enclose a case bottom wall 8a to the external surface of a motor shaft 7, and the hair release prevention frame 12b of circular arc shape for connecting the ends of the aforesaid projections to each other. When drawn with the fan 6 and entrapped in a space between the fan 6 and the case bottom wall 8a, a hair K is squarely taken up, forming a linear shape on adjacent hair curl frames 12a and 12a, and the slip thereof is prevented with the edge E of each frame 12. Also, the hair release prevention frame 12b can prevent the hair K from being detached from the projected end of the hair curl frame 12a. In this case, the hair K can be curled about the hair curl frame 12a by a portion corresponding to the height of the hair release prevention frame 12b from the hair curl frame 12a. The height becomes all the more larger when open width W is made larger between the hair curl frames 12a and 12a.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hair dryer equipped with means for preventing hair from winding around a motor shaft.

[Conventional technology]

As this type of hair dryer, as shown in FIG.
An upper winding cylinder 20 that surrounds the entire circumference of the fan 6 is provided, and a flange 21 is formed at the projecting end of the upper winding cylinder 20 so as to extend outward in the radial direction. 33
Publication No. 324).

Therefore, according to this, the hair sucked in by the fan 6 is wound around the upper winding cylinder 20, so that it can be prevented from winding around the shaft 7 of the motor 5, and moreover, the hair that is wound around the upper winding cylinder 20 can be prevented from wrapping around the upper winding cylinder 20 on the side that protrudes from the upper winding cylinder 20. The flange 21 can restrict the end from being pulled out in the axial direction.

[Problem to be solved by the invention]

However, when the upper winding cylinder 20 is formed into a cylindrical wall shape as in the above-mentioned upper winding prevention stage f, the flange 21 is also formed on the core upper winding cylinder 20.
If you add , the following new problems will arise.

That is, if the upper winding cylinder 20 has a cylindrical wall shape, one end of the hair gets entangled thereon and slips in the circumferential direction even when the hair starts to wind, which may make winding difficult.

Also, the diameter D of the flange 21 relative to the diameter of the upper winding tube 20
2 is preferably larger in order to increase the amount of curled hair on the upper winding tube 20 and to ensure that hair is not pulled out from the protruding side end of the upper winding tube 20. However, since the outer diameter of the blades 6a of the fan 6 is determined to be a constant size, if the diameter D2 of the flange 21 is set to be large under this condition, the blade base of the fan 6, which has an umbrella-shaped cross section, in which the flange 21 is accommodated. The diameter of the space formed on the motor side of the blade 6b must be increased, which is not preferable because the shape of the blade 6a becomes smaller and the air blowing ability is reduced.

Therefore, in order to ensure the size of the blades 6a of the fan 6, there is a natural restriction on the expansion of the diameter D2 of the flange 21, and it is necessary to sufficiently prevent the hair from coming off and increase the amount of hair. The flange diameter D2 is difficult to obtain, and there is still room for improvement in this respect.

Therefore, the present invention provides a hair dryer equipped with a hair curl prevention means as described above, by improving the structure of the hair curl prevention means, ensuring the size of the fan blade, and preventing hair from coming off. The purpose is to increase hair volume.

Another object of the present invention is to prevent the hair from slipping, thereby stably and reliably winding the hair, thereby improving reliability.

[Means to solve the problem]

In order to achieve the above object, in the hair dryer of the present invention, as shown in FIG. 1 and FIG. , so to speak, the conventional flange 21 mentioned above.
The curl prevention frame 12 is configured by cutting out a part of the peripheral wall of a divided cylinder 13a obtained by dividing the upper winding cylinder 20 or the core part 20 without a mark into several parts in the circumferential direction. That is, the curl prevention frame 12
is a cylinder 13 that protrudes open from one of the motor holding case 8 or the fan 6 toward the other so as to surround the outer periphery of the motor shaft 7, or a peripheral wall of a divided cylinder 13a obtained by dividing the cylinder 13 into several parts in the circumferential direction. At least one pair of seven straight wrapping frames 12a, 12a extending in the axial direction, and a circular or arc-shaped hair removal prevention frame 12b connecting the protruding side ends of the hair wrapping frames 12a, 12a. It is formed into a shape having the following.

[Effect]

The hair wraps around the hair wrapping frames 12a, 12a (and exhibits a polygonal hair curling state, and the curly hair increases the sliding friction in the winding direction at the apex corner (ridge line) of the polygon, Slips during hair removal can be reduced, and hair can be wound more stably and reliably.

In addition, the curly hair can be prevented from coming off from the protruding side end of the hair wrapping frame 12a by the hair removal prevention frame 12b.

In particular, the bristling prevention frame 12b is completely different from the shape of the flange 21 that extends further radially outward from the protruding side end of the conventional upper winding cylinder 20 described above, so to speak.
Alternatively, since it is constituted by a part of the peripheral wall itself of the divided cylinder 13a obtained by dividing the core part 20 into several parts in the circumferential direction, only the diameter D1 of the conventional upper winding cylinder 20 is required to form the hair retaining frame 12b. Therefore, it is possible to increase the amount of upper winding and prevent the blades from coming off without reducing the size of the blades of the fan 6.

〔Example〕

An embodiment of the hair dryer according to the present invention will be described with reference to FIGS. 1 to 5.
