Description

[Detailed description of the invention] The present invention relates to a hair dryer in which an attachment such as a comb or a brush is removably attached to the hot air outlet. Alternatively, it is designed to prevent burnout and to obtain high-temperature hot air.

Generally, the cylindrical body of this type of hair dryer is molded from a thermoplastic resin suitable for mass production, such as styrene-based ABS. By disposing a heat generating device surrounded by and blowing air from one side, hot air is discharged from an opening at one end, that is, a hot air outlet.
Alternatively, if attachments such as brushes are attached, these will create some resistance, and the hot air to be discharged will stay inside the main body, especially near the hot air outlet, and this heat may cause thermal deformation or burnout of the cylindrical main body. Ta. Of course, such drawbacks can be compensated for by reducing the amount of heat generated, but on the other hand, the temperature of the hot air that can be discharged to the attachment side is too low, making it impossible to achieve the desired hair styling.

The present invention has been devised in view of these points, and one embodiment thereof will be described below with reference to the drawings. Reference numeral 1 denotes a cylindrical main body, which has a left case 2 and a right case 2' molded from a thermoplastic resin such as styrene-based ABS and abuts each other to form a long cylinder, and has an annular body formed from, for example, a metal material at both ends. The left and right cases 2, 2' are constructed so as not to be separated by fitting the cylinders 3, 3' together.
A heat generating device 4 and a blower device 5 for blowing air to the heat generating device are built into the cylindrical body 1,
Hot air obtained by the air blowing device 5 is sent out from a hot air outlet 6 formed at one end of the cylindrical body 1. Of course, a suction port 7 is provided at the other end so that outside air can be introduced through the suction port. Reference numeral 8 denotes a power cord electrically connected to the heat generating device 4 and the blower device 5.

The heat generating device 4 is constructed by surrounding a heat generating element 9 with a heat shield tube 10, and the heat generating element is formed by wrapping a nichrome wire 11 around a winding frame 12 made of asbestos plate material, and one of the heat shield tubes 10 is made of metal. A plate material is formed into a cylindrical shape, and the heating element 9 is surrounded and supported within the heat shield tube 10. The tip of the heat shield cylinder itself 13
is formed as an extension. One blower device 5 is an electric blower fan 1 which is rotationally driven by an electric motor 14.
It is composed of 5. Reference numeral 16 denotes a ring portion made of a heat-resistant resin material such as nylon resin, which is joined in communication with the tip portion 17 of the cylindrical body 1, and its inner wall surface 18 is connected to the inner wall surface of the tip portion 17 of the cylindrical body 1. They are formed so as to form the same surface. Further, the heat shielding tube tip portion 13 is positioned on the inner wall surface 18 of the ring portion 16. 20 is the ring portion 1
The lattice body is attached to the tip of the cylindrical body 1.
It acts like a protective net to prevent objects from being inserted inside. The ring portion 16 and the lattice body 2
0, when the annular cylinder 3 is fixed to the cylindrical body 1 with, for example, screws 19, the outer periphery of each annular cylinder 3 is
and the tip of this annular cylinder 3 and the cylindrical body 1
It is clamped and fixed with the tip of the. Reference numeral 21 denotes an attachment such as a comb or a brush, which is detachably attached to the hot air outlet 6.

As mentioned above, the hair dryer of the present invention includes a heat generating device in which a heat generating element is surrounded by a heat shield cylinder, and a blower device that blows air into the heat generating device using an electric blower fan.
In the hair dryer, an attachment such as a comb or a brush is removably attached to the hot air outlet of a cylindrical main body that can be divided into left and right parts, the main body being configured to blow out hot air from a hot air outlet formed at one end. The cylindrical body is made of a molded body of thermoplastic resin, and the divided ends thereof are covered and engaged with an annular tube, and the inner wall surface of the cylindrical body is flush with the inner wall surface of the tip of the cylindrical body. A ring portion made of a heat-resistant resin and a grid body for a protective net are sequentially arranged, and these are clamped and fixed between the annular tube and the tip of the cylindrical body,
Furthermore, since the tip of the heat shield tube extends near the hot air outlet, even if hot air is trapped inside the cylindrical body, especially near the hot air outlet due to the installation of the attachment, the cylindrical body will not close as usual. It is possible to obtain a practical hair dryer in which the hair is not deformed by heating, the heat generation amount of the heating device can be increased, and hair styling can be performed well.

Since the tip of the cylindrical body and the inner wall surface of the ring part are flush with each other, it is possible to form a ventilation passage without reducing the opening area of the hot air outlet. It is possible to efficiently discharge the air sent from the

Furthermore, since the divided ends of the cylindrical body are covered and engaged with the annular tube, and the ring portion and the lattice body are respectively clamped and fixed between the tip of the annular tube and the tip of the cylindrical body, This eliminates the need for special members for fixing each of the ring portion and the grid body, improving work efficiency.
