In general, the main body case itself made of a plastic material is decorated with a multicolored plastic material, or a pattern is formed on the outer surface of the main body case by screen printing. However, in such a case, it is necessary to prepare various kinds of main body cases with different patterns by changing only the decoration on the surface with the same model.

  Therefore, when selling hair dryers of the same model with different surface decorations, such as the hair dryer described in the following Patent Document 1 (Japanese Patent Laid-Open No. 6-125810), the main body case is shared, different colors, designs, etc. Prepare a wide variety of different decorative bodies such as patterns, and select any one of them and place it on the inner surface of the main body case to easily create a hair dryer with a wide variety of surface decorations. And there was something that was going to be obtained at low cost.

  FIG. 4 is a side view showing the configuration of the hair dryer described in Patent Document 1, and FIG. 5 is a cross-sectional view of the main body portion. The hair dryer main body 51 includes a heat insulating cylinder 60, an insulating inner cylinder 62 for holding a heater 57 provided in front of a holding cylinder of the motor 59 disposed inside the heat insulating cylinder 60, and an outer periphery of the insulating inner cylinder 62. The projecting radiation plate 63, the heater 57 wound around the outer periphery of the radiation plate 63, the insulating outer cylinder 64 surrounding the outer periphery of the heater 57, the heat shield cylinder 60 inserted into the inner surface and fitted together, and the main body case 51 Consists of. The main body case 51 is configured to be transparent, and on the inner surface of the main body case 51, the decorative body 70 is disposed between the main body case 51 and the heat shield cylinder 60 of the heater portion therein. The color or the pattern is seen through from the main body case 51.

  In addition, although not shown, series products with different apparent impressions are inexpensive by simply changing the colored body arranged inside the main body case as disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2001-61536). A hair dryer that can be manufactured in a manner that can express the impression of appearance, particularly a deep shade similar to a colored molded case, and provides a color structure that does not show scratches, etc. Some of the front case, which occupies most of the part, was translucently colored and molded into milky white. This colored product is also formed by printing with fluorescent ink on one side of a heat-resistant plastic sheet.

  Furthermore, the hair dryer described in the following Patent Document 3 (Japanese Patent Application Laid-Open No. 2003-153732) exhibits a gradual color change while expressing a color tone of a product, particularly a deep hue as an appearance impression. It is intended to provide a visually and sensually beautiful case body, which is composed of a colored sheet placed on the inner surface of a case made of a translucent plastic molded product. In the middle region, a region having dots of the same color as one region on both sides is provided, and in the intermediate region of the colored sheet, the size of the dots is changed from one region side to the other region side. The closer it gets, the smaller.

However, in the hair dryers described in Patent Documents 1 to 3, in any case, a decorative body that is decorated, or a colored body that is formed by printing with fluorescent ink on one side of a heat-resistant plastic sheet. Alternatively, a colored sheet with special coloring must be prepared separately, inserted inside the main body case, and attached to the outer periphery of the heat shield cylinder. Then, since the cost of the member and the man-hour for attachment are required, an object that can change the decorative design without preparing such a special decorative body is desired.

  The hair dryer 1 of FIG. 1 includes a cylindrical main body 11 and a handle 12 attached near the rear end of the lower surface of the main body. The handle 12 is pivotally supported with a holding portion protruding from the lower surface of the outer case 13 as a fulcrum, and is attached to the main body 11 in a foldable manner. The handle 12 is provided with a power switch 14.

  The outer case 13 of the hair dryer 1 includes a front portion 13a, a rear portion 13b, a rear cover 15, and a discharge nozzle 16. The front part 13a and the rear part 13b of the outer case and the discharge nozzle 16 are formed of a molded product of a heat-resistant transparent plastic material such as polycarbonate or heat-resistant ABS resin. As shown in FIG. 2, the outer case 13 is composed of two parts, and the front part 13a has a substantially cylindrical shape with the profile of the longitudinal section tapered forward. The rear portion 13b has a short cylindrical shape and is joined to the front portion 13a. The rear end of the main body 11, that is, the rear end of the rear portion 13b of the outer case is a rear cover 15, which is an air inlet provided with a plurality of holes for introducing outside air, and is a metal having a number of honeycomb-shaped holes. The plate is mounted in a circular dome shape. The front end opening of the front portion 13a of the outer case serves as a wind blowing port, and the discharge nozzle 16 is rotatably attached thereto.

  As shown in FIG. 1, a hot air generation chamber 17 is disposed inside the outer case 13 of the main body 11. That is, the hot air generating chamber formed in a cylindrical shape has an insulating outer cylinder 17b disposed inside the outer wall 17a, and a blower grill 21 is attached at a position where hot air is blown outside the tip of the hot air generating chamber 17, so that the insulating outer cylinder is provided. A heat source 18 such as a nichrome wire is accommodated in the interior of 17 b, and a fan motor 19 for sending air is accommodated behind the heat source. After that, a blower chamber 20 is provided, and a fan 20 a connected to the motor 19 is provided. The air blowing chamber 20 sends the air taken in from the air inlet of the rear cover 15 to the hot air generating chamber 17 by the fan 20a.

  As shown in FIG. 2, a plurality of heat radiating plates 22 are provided in the hot air generating chamber 17 so as to be arranged radially in the axial direction of the hair dryer main body 11 from the insulating cylinder 23 housing the motor 19 to the front part. Nichrome wire or the like (not shown) is wound so as to connect the outer edges of the heat radiating plates 22. The wind of the fan 20a in the blower chamber 20 connected to the motor 19 is sent to the front discharge nozzle 16 between the heat radiating plates 22.

  The basic shape of the outer wall 17a of the hot air generating chamber 17 made of aluminum, galvanized steel, stainless steel or the like is shown in a longitudinal section in FIG. 1 and in a perspective view in FIG. The outer surface is molded so as to have a plurality of corrugated irregularities perpendicular to the vertical direction, and the outer surface is subjected to treatment such as polishing and plating so that reflection is good. In the figure, the corrugation is shaped to have three peaks, but the number is not limited. However, from the relationship of creating a shadow, it seems that two concaves and three convexes are preferable. The corrugated irregularities are formed in a convex shape having a large inner diameter so that the air flow path becomes larger on the intake side. By doing this, the outer wall 17a does not hinder the smooth inflow of air, so that an efficient hair dryer can be obtained.

  For example, the outer wall 17a of the hot air generating chamber 17 is molded by pressing a metal tube and a metal plate to perform drawing, or by rolling a plurality of elongated metal plates and connecting the end portions thereof. You may shape | mold by combining. It can also be formed by molding an opaque heat-resistant plastic material. When using a heat-resistant plastic material, the surface may be colored with a desired pigment, or the surface may be treated with a highly reflective coating such as a white paint or an aluminum vapor deposition film.

  In the hot air generating chamber 17, the heat radiation plate 22, the heat source 18, the motor 19, the fan 20 a and the like are incorporated in the blower chamber 20, and further these components are incorporated in the outer case 13 of the main body 11. In the step of butt-joining the rear portion 13b of the outer case, the heat source 18 and the motor 19 are disposed in the front portion 13a in the front-rear direction, and the heat source 18 and the motor 19 are stored in advance. Is covered with an outer wall 17a of a hot air generating chamber 17 which is made of a metal which is easy to reflect heat rays, such as aluminum and stainless steel, and which is excellent in luster and light color, and serves as a heat shielding means. The blower chamber 20 is housed in the upper part, and the hot air generating chamber 17 is inserted into the front part 13a of the outer case from behind the front part 13a.

  In this case, the fan 20 a connected to the motor 19 is fitted into a fan holding cylinder of the air blowing chamber 20 disposed on the rear side of the hot air generating chamber 17. The motor 19 is fitted in an insulating cylinder 23 formed in a shape for holding a heat source whose front end is arranged inside the hot air generating chamber 17. A heat source heater is wound around the outer periphery of a plurality of heat radiating plates 22 projecting radially from the outer periphery of the insulating cylinder 23. Further, the outer periphery of the heater is surrounded by an insulating outer cylinder 17b such as a mica sheet concentrically integrated with the insulating cylinder 23 so as to connect the heat radiating plates 22, and the insulating outer cylinder 17b is formed on the outer wall 17a of the hot air generating chamber. Inserted and fitted on the inner surface.

  The outer case 13 of the hair dryer main body 11 is transparent or translucent so that the shadow of the outer wall of the hot air generating chamber 17 can be seen, and may be colored in any single color. Moreover, it may be processed non-colored and translucent. When the shadow of the corrugated irregularities on the outer wall 17a of the hot air generating chamber 17 is seen through the outer case 13, the light transmitted through the outer case 13 strikes the wall and is reflected, and changes depending on the viewing position, creating various patterns. Aesthetic sense can be generated. As a result, it is possible to provide a hair dryer with excellent design without special decoration such as a pattern and color.

  In addition, the corrugated irregularities of the outer wall 17a of the hot air generating chamber 17 create a space between the outer case 13 and an air layer can be secured there. In addition, the outer wall 17a has a large surface area, so a high heat shielding effect. Can be obtained.

  The outer wall of the hot air generating chamber 17 has a plurality of corrugated irregularities parallel to the longitudinal direction of the hot air generating chamber 17, as shown in the cross section of the hair dryer in which the internal mechanism is omitted in FIG. You may shape | mold. Incidentally, the outer wall 17a 'shown in FIG. 3 is an example in which eight waves are provided in the circumferential direction of the hot air generating chamber. The shape of the waveform of the outer wall 17a 'is not limited. However, since the change is poor when there are too few irregularities, it is preferable to select and provide an appropriate number of irregularities from the relationship of creating a shadow. . Further, the unevenness of the outer wall 17a 'may be formed to have a plurality of corrugated unevenness with an angle with respect to the longitudinal direction of the hot air generating chamber 17, and the wave shape also moves smoothly between peaks and valleys. In addition, for example, the shading portion can be made smooth and the valley portion can be angled, so that the shading can be finely changed. In addition, not only one type of wave but also two or more types of corrugated irregularities may be mixed, thereby giving a finer change to the shadow.

  In the hair dryer of the present invention, if the outer case of different colors is prepared, it is possible to provide products with different decorations for several models, and the user can enjoy beautifully visually and sensorily with one purchased model. You can enjoy a variety of complex design changes.

  The electrothermal hair dryer has been described above. However, the present invention is not limited to the electrothermal method, and can be applied to a gas combustion type hair dryer.

  In the above hair dryer, the hot air generating chamber has been described as a cylindrical shape, but according to various hair dryers such as a hair dryer, a hair blocker or a hand dryer, according to the outer case and the arrangement of other components in the case. It is easy to design the hot air generating chamber in another form, and the deformation is free.
