Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair dryer equipped with a cylindrical hair winding body for winding and curling hair.

Generally, as shown in FIG. 1, such a hair winding body is made of a bottomed cylinder having a hot air passage 7 inside, and has a first hot air outlet 11 formed in its peripheral wall and a large number of bristles 16 implanted therein. A brush attachment is known in which the hair winding body 8 is fitted into the outlet (not shown) of the hair dryer main body.
Hair is wound around the hair winding drum 8, and the hair is heated and curled by hot air discharged from the first hot air outlet 11.

However, when hair is wound around the hair winding drum 8, the first hot air outlet 11 may be blocked by the hair and the hot air may become trapped inside, causing an abnormal temperature rise. A second hot air outlet 13 is formed at the base of the peripheral wall of the winding drum 8, and the first
When the hot air outlet 11 of the hot air outlet 11 is blocked, the hot air is discharged to the outside from the second hot air outlet 13.

However, since the second hot air outlet 13 is formed at the base of the peripheral wall of the hair winding body, when a large amount of hair is wound, the hair is wound up to the base of the hair winding body 8, and the second hot air outlet 13 is formed at the base of the peripheral wall of the hair winding body. There was a problem that the hot air outlet 13 was also blocked at the same time, causing an abnormal temperature rise inside the hair dryer.

In order to solve the above-mentioned problems, some hair winding cylinders have an opening formed at the tip to allow hot air to escape, but when a large amount of hair is wound, a lot of hot air flows through the tip. The hot air escapes from the opening and is not discharged onto the hair wrapped around the tip, and the hot air is not discharged uniformly over the entire hair wrapping body, resulting in uniform drying and curling of the hair. There was nothing I could do.

The present invention has been made in view of such problems, and its purpose is to provide a second hot air outlet at a position where it will not be blocked by hair even when a large amount of hair is wound around the hair wrapping body. To provide a hair dryer which improves safety by providing a hair dryer and which can apply hot air substantially uniformly to wound hair.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4 of the drawings. Reference numeral 1 denotes a cylindrical main body housing in which an opening 3 forming a suction port 2 and a discharge port is formed, and a fan 5 rotated by a motor 4 and a heater 6 are accommodated therein, and the opening 3 has an open end. The hair winding body 8 is made of a cylindrical body with a bottom at the other end and has a hot air passage 7 thereinto, and the open end of the hair winding body 8 is communicated with the opening of the main body housing 1. . The hair winding body 8 includes a metal curl pipe 9 having one end fixed to the opening 3;
It consists of a curl brush 10 that is removably fitted onto the outer periphery of a curl pipe 9. The curl pipe 9 has a first hot air outlet 11 formed on its peripheral wall, and an inner cap 12 is fitted to the tip thereof, and one end is connected to the hot air passage 7 in the curl pipe 9 between the inner cap 12 and the curl pipe 9. A guide cylinder 26, which is sandwiched between the guide cylinders and has a bottomed cylinder shape and has a hot air circulation hole 25 in the bottom wall, is disposed on a coaxial axis with the curl pipe 9 and with a gap between it and the inner circumferential wall of the curl pipe 9, The hot air is guided by the guide cylinder 26 to increase the amount of hot air discharged from the first hot air outlet 11 formed on the rear side of the curl pipe 9. The hot air is uniformly discharged from the discharge port 11 of. Further, the inner cap 12 has a second hot air outlet 13 formed on the same axis as the curl pipe 9, and a groove 14 on the outer periphery. The curl brush 10 has a sheet-like bristle base 17 made of silicone rubber and integrally formed with a large number of bristles 16 wound around the outer periphery of a metal inner pipe 15, and uses the softness of the silicone rubber to curl the hair. This prevents hair from getting entangled with the bristle 16 during winding and unwinding. A first hot air outlet 18 is formed on the peripheral wall of the curl brush 10 at a position corresponding to the first hot air outlet 11 of the curl pipe 9, and an outer cap 19 is fitted at the tip. A second outlet 20 is formed in the outer cap 19 on a coaxial axis with the curl brush 10, and a lattice 21 is provided in the second outlet 20 to prevent foreign objects such as fingers or hairpins from entering. There is. Further, a spring 22 is attached to the inner peripheral surface of the outer cap 19, and the spring 22 elastically engages with the groove 14 formed on the outer periphery of the inner cap 12 of the curl pipe 9, thereby causing the curl pipe 9 to curl. The brush 10 can be removably fitted. The hair dryer of this embodiment can be used with the curl brush 10 fitted into the curl pipe 9 as shown in FIGS. 2 and 3, or with the curl brush 10 removed (not shown). When used with the curl brush 10 removed, the hair is held and curled with a hair holding plate 24 disposed on the outer periphery of the curl pipe 9, which can be opened and closed by operating the operation button 23. This is the process of attaching them. Further, the hot air blown from the hair dryer body passes through the hot air passage 7 as shown by the arrow in FIG.
The hot air is discharged to the outside from the first hot air outlets 11, 18 and the second hot air outlets 13, 20, but when the hair is appropriately wound around the hair wrapping body 8, The guide cylinder 26 and the inner and outer caps 12 and 19 provided in the front act as an obstacle to air blowing, and a large amount of hot air is discharged from the first hot air outlet 11 and 18 and hits the hair wound around the hair winding body 8, resulting in an effect. When the amount of curling of the hair increases and the first hot air outlets 11 and 18 become blocked, the hair from the second hot air outlets 13 and 20 can be curled. This increases the amount of hot air discharged and prevents hot air from getting trapped inside the hair dryer.

FIG. 5 shows different embodiments of the guide tube 26,
A plurality of steps are formed, the diameter of which becomes smaller as one goes toward the front in the air blowing direction, and the steps guide the hot air toward the first hot air discharge ports 11 and 18, and the hair winding body 8 The amount of hot air discharged from the first hot air discharge port 11 formed over substantially the entire length in the axial direction becomes more uniform.

Incidentally, in the above embodiment, a brush attachment formed separately from the main body housing of the hair dryer and having bristles implanted on its outer periphery was shown as a hair winding body, but the hair winding body of the present invention is not limited to this. Instead, the hair winding body may be formed integrally with the main body housing, or the hair winding body may have no bristles implanted therein, or a comb may be detachably attached to one side of the hair winding body.

As described above, the present invention forms the first hot air outlet in the peripheral wall of the hair winding body, which is made of a cylindrical body with an open end at one end and a bottom at the other end, and has a hot air passage inside the cylinder, and the other end is formed with a first hot air outlet. A second hot air outlet is formed in the bottom wall of the hair winding body, and a gap is provided on the side of the second hot air outlet in the hot air passage with the inner circumferential wall of the hair winding body on a concentric axis with the hair winding body. A guide tube is provided, and a second guide tube is provided in the gap.
A cylindrical body housing is provided which closes the hot air outlet side of the hair coiler and connects the guide tube and the second hot air outlet, and which communicates with the open end of the hair coiler. Even if the first hot air outlet is blocked by winding a lot of hair, the second hot air outlet formed on the bottom wall will not be blocked by the hair, and the amount of hair wound will increase and the first hot air outlet will be blocked. As the rate at which the hot air outlet is blocked increases, the amount of hot air discharged to the outside from the second hot air outlet increases, and as in the conventional example, hot air is trapped inside the hair dryer and the temperature rises abnormally. This improves safety.

The guide cylinder allows air to be blown to the first hot air outlet at the tip, making it possible to evenly eject hot air over almost the entire axial length of the hair winding cylinder, thereby drying the hair uniformly. This allows you to quickly curl your hair and curl it.
