[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to a hair dryer,
In particular, the power switch is characterized by its mounting structure.

[0002]

2. Description of the Related Art A hair dryer of this type is disclosed, for example, in Japanese Utility Model Laid-Open Publication No. 58-169802, and FIG.
6 and FIG. There, when assembling, first, the power switch 24 is assembled and fixed to a support frame 55 separate from the upper and lower cases 1a and 1b of the main body case 1, and then the support frame 55 is fitted and fixed inside the upper case 1a. The heat generating device 5 having the heater 17 built in the heat shield cylinder 19 is assembled to the support frame 55, and finally the lower case 1b is butted against the upper case 1a.

[0003]

However, in the above-mentioned conventional example, the support frame 55 which is separate from the main body case 1 is required, so that not only the number of members increases but also the power switch 24 when assembling it. A pre-assembly step for the support frame 55 is required. Also, the power switch 24
Are pre-assembled on the support frame 55, and then the heating device 5 and the blower 6 connected to the power switch 24 and the lead wire 20 in advance are connected to the upper case 1a or the lower case 1b.
Since the power switch 24 cannot be moved on the support frame 55 when the power supply switch 24 is installed at a predetermined position in the upper case 1a or the lower case 1b, it is difficult to install the power supply switch 24 at a predetermined position in the upper case 1a or the lower case 1b. It may be difficult to avoid biting 20. In this case, the power switch 24 must be disassembled from the support frame 55, which is very troublesome. An object of the present invention is to improve the assembling structure of a power switch to a main body case in a hair dryer having the power switch and the heat generating device as described above, thereby omitting the support frame and assembling the support frame. The point is to achieve omission and improve the assembling workability.

[0004]

According to the present invention, a heating device 5 is provided inside a main body case 1 which is formed in a cylindrical shape which is long in the front-rear direction by abutting an upper case 1a and a lower case 1b as shown in the figure. And the blower 6 are housed side by side, and the heating device 5 and the blower 6
And the power supply switch 24 connected via the power supply switch 24. The positioning means 37 of the heat generating device 5 and the blower 6 are provided inside at least one of the upper and lower cases 1a and 1b.
39, an opening 33 is formed in one of the upper and lower cases 1a and 1b so that the power switch 24 can be inserted from the inside of the case 1a or 1b to the outside together with the lead wire 20; A switch support surface 35 capable of temporarily supporting the power switch 24 is provided around the outside, and the power switch 24 is provided on the switch support surface 3.
5 is fixed by being pressed against the upper surface by a switch panel 29.

[0005]

Since the power switch 24 is directly supported on one of the switch support surfaces 35 of the upper and lower cases 1a and 1b, the above-described conventional support frame and the assembly thereof can be omitted.

[0006] Heating device 5, blower 6 and lead wire 2
0 is connected to the upper case 1
a or the inside of the lower case 1 b, the lead wire 20 is inserted through the opening 33 together with the lead wire 20, temporarily supported on the outer switch support surface 35, and then completely pressed and fixed by the switch panel 29. Therefore, before assembling the switch panel 29, the power switch 24 is suspended by the lead wire 20, that is, in a free state. Lower case 1b without worrying about
Alternatively, it can be easily aligned with the positioning means 37 and 39 on the inner surface of the upper case 1a and assembled. After the assembly, the lead wire 20 inserted outside from the opening 33 is subjected to wire processing to support the power switch 24 as a switch. Face 35
What is necessary is just to position it on the upper side and press and fix it with the switch panel 29.
