Description

[Detailed description of the invention] The present invention relates to a hair dryer in which the handle is rotatably supported on the handle support part of the dryer body. It is an object of the present invention to provide a hair dryer which can be made compact, the display part of a changeover switch installed in a handle support part can be easily seen from the outside, can provide reliable display, and has a good external design. .

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a dryer main body formed by integrating left and right halves of cases 2 and 3 by tightening screws or the like, and the lower central part of a cylindrical main case 4 with openings at the front and rear (left and right in Fig. 1). The handle support portion 5 is integrally molded and bulges out.

Reference numeral 6 denotes a motor disposed inside the large diameter portion at the rear of the main body case 4, and a blower fan 8 is attached to the rotating shaft 7 of the motor.

Reference numeral 9 denotes an electric heater disposed in a small diameter portion at the front of the main body case 4, and this, the motor 6, and the blower fan 8 constitute a hot air device 10.

Further, 11 is a cover having a large number of intake holes 11a attached to the rear opening of the main body case 4, and 12 is the main body case 4.
This is a nozzle having a blowout hole 12a attached to the front opening of the nozzle.

13 is a hot air generator 10 disposed inside the handle support part 5
This is a power switch serving as a control changeover switch, and its operation button 13a is made to protrude outward through a through hole 14 formed in the front surface of the handle support portion 5.

The power switch 13 is operated in three stages by pressing the operation button 13a.
Both the motor 6 and the electric heater 9 are energized in the second stage (hot air), only the motor 6 is energized in the second stage (cold air), and the third stage is energized.
In the second stage, both the motor 6 and the electric heater 9 are cut off.

Reference numeral 15 denotes a circular display board as a display section, one side of which is divided into six parts along the center line and sequentially colored in three different display colors, for example, red, blue, and white.

This display board 15 is fixed to a shaft 16 projecting laterally from the power switch 13, and is configured to rotate by 60 degrees in a predetermined direction every time the operation button 13a is pressed once.

Reference numeral 17.17 indicates a support hole drilled approximately in the center of both sides of the handle support portion 5, reference numeral 18.18 indicates a screw hole provided a predetermined length below the support hole 17, and reference numeral 19 indicates a predetermined length above the support hole 17. This is a first through hole bored so as to face the display board 15.

Reference numeral 20 denotes a handle, which is made by molding handle members 21 and 22 that are divided into left and right halves, butted against each other and integrated with a screw 23, and the shaft parts 24, 24 protruding from the inner surface of the base end are inserted into the support hole 17. . A circular recess 26°26 surrounded by .25 is formed.

Although not shown, the handle 20 is moved from a position perpendicular to the dryer main body 1 by an arrow A as shown by a solid line in FIG.
The handle 2 can be rotated in a range of 90 degrees backwards, and the handle 2 can be rotated at both ends of the rotation range and at predetermined positions in the middle.
0 is provided with an articulation mechanism that stops the rotation in multiple stages.

27.27 is the shaft part 2 in the recessed part 26 of the handle members 21 and 22.
The third through holes are each formed in an arc shape centered at 4,
These face the screw holes 18.

28 is a third through hole 27 in the recess 26 of one handle member 21.
A second through hole is also formed in an arc shape centered on the shaft portion 24, and is opposite to the first through hole 19.

29 and 30 are decorative plates having a screw insertion hole 31, which are disposed in a fitted state in the recesses 26 and 26, respectively, and are screwed into the screw hole 18 through the screw insertion hole 31 and the through hole 27. The base end of the handle 20 is rotatably held between the handle support 5 and the decorative plates 29 and 30.

33 is a short cylindrical display window protruding inward from one of the decorative plates 29, which is connected to the second through hole 28 and the first through hole 1.
9 and its tip is located near the display board 15.

According to this embodiment configured in this way, the decorative plates 29 and 30 are fixed to the handle support portion 5 of the dryer main body 1 via flat head screws 32, and the display window 3 provided on the decorative plate 29
3 and the display board 15 of the power switch 13 disposed in the handle support part 5 maintain a constant positional relationship even when the handle 20 is rotated. The switching operation status of the power switch 13 is displayed on the display board 15 for easy viewing.
It can be easily distinguished by the displayed color, and the display window 3
3 does not move relative to the handle support 5, it is possible to reliably prevent a portion of the display color different from the actual switching operation status of the power switch 13 from being exposed from the display window 33, and to ensure reliable display. can.

Now, in the hair dryer, the power switch 13 is located on the handle 2.
near the handle 20 so that it can be operated while holding the
Furthermore, it is desirable to provide the power switch 13 on the side of the dryer body 1 so that the lead wires from the power switch 13 are not bent when the handle 20 is rotated. Therefore, it is ideal to have the power switch 13 built into the handle support part 5. In addition, it is necessary to provide the handle 20 with a pivot point as close to the dryer body 1 as possible so that it can be made more compact when rotated and folded. In order to satisfy both the requirements of compactness, the display section 15 of the power switch 13 and the base end of the handle 20 must necessarily overlap.

By the way, when the decorative plate 29 of this embodiment is omitted, the display plate 15 is inserted into the second through hole 28 and the first through hole 1.
Since the second through hole 28 rotates with the rotation of the handle 20, it becomes difficult to see the display section 15, and the arc-shaped second through hole 28 is visible from the outside through the second through hole 28. Although the appearance deteriorates due to exposure, in this embodiment, the decorative plate 29 having the display window 33 is fitted into the recess 26 and fixed to the handle support part 5 via the countersunk screw 32, so the appearance is improved. can also be greatly improved.

The present invention, as explained above, makes the changeover switch easy to operate, and when the handle is rotated, it can be made as compact as possible, and the display part of the changeover switch installed inside the handle support part is easy to see from the outside and provides a reliable display. It is possible to provide a hair dryer that is capable of performing the following functions and also has a good external design.
