Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary foldable hair dryer.

In the conventional hair dryer A', as shown in FIGS. 1 to 3, the end of the handle cover 1 and the end of the main body cover 3 are rotatably connected, and the U-shaped The motor 5 is fixed to one end side wall 1a using a motor fixture 7' with a screw 12, and the motor 5 is fixed to one end side wall 1a of the handle cover 1 with a screw 12.
The rotation spring 13 is attached to the periphery of the rotation spring 13.
A fitting protrusion 9' is provided by protruding an approximately central portion of the handle cover 1 outward from the outer periphery of the end of the handle cover 1, and a rotating spring is provided at the end of the main body cover 3 along the outer periphery of the side wall 1a of the cover main body 1. Two fitting recesses 10' are provided opposite to the rotation spring 13, and the rotation spring 1 is inserted into the fitting recesses 10'.
By inserting the fitting protrusion 9' of 3 in a detachable manner, the handle cover 1 and main body cover 3 can be folded up when not in use, and opened at a 90° angle when in use. It is set as. However, in this conventional example, the number of parts such as the attachment of the rotary spring 13 increases, and the number of assembly steps also increases, leading to an increase in costs.

The present invention has been developed in view of the above points, and its purpose is to enable the handle cover to be held and used at any angle.
To provide a hair dryer that does not require an increase in the number of parts, is easy to assemble, and can reduce costs.

An embodiment of the present invention will be described below with reference to FIGS. 4 to 8. A is a hair dryer, and U of the handle cover 1 which functions as a handle
The ends of the body cover 3 housing the heater 2 are sandwiched between the letter-shaped ends, and the circular side wall 1a provided with the suction port 11 at the end of the handle cover 1 is inserted into circular openings on both sides of the ends of the body cover 3. 3a to rotatably connect the end of the handle cover 1 and the end of the main body cover 3. A cylindrical motor 5 is connected to the connecting portion 4 between the end of the handle cover 1 and the end of the main body cover 3 on one side wall 1a of the handle cover 1.
The motor is fixed and housed in the center of the inner surface using a motor fixture 7. That is, the motor fixing device 7 has three fixing pieces 7b hanging downward from the outer peripheral edge of a substantially circular fixing device main body 7a at a constant interval, and a mounting piece 7c extending outward from the tip edge of the fixing piece 7b. The motor 5 is fitted between the fixing pieces 7b of the motor fixture 7, and the screws 12 are inserted into the side wall 1a of the end of the handle cover 1 through the screw holes 14. The motor 5 is fixed to. The rear end of a rotating shaft 16 whose tip protrudes from the central opening 15 of the fixture main body 7a of the motor fixture 7 is attached to the upper surface of the motor 5, and the fan 6 is attached to the tip of this rotating shaft 16. It is rotated by a motor 5. 17 is a protrusion for preventing the motor 5 from coming off; 18 is a hole provided at the base end of the fixing piece 7b of the motor fixture 7;
Install the anti-vibration screw (not shown). One mounting piece 7c of the motor fixture 7 is provided with an arm piece 8 whose distal edge extends and whose distal end protrudes outward from the outer peripheral edge of the side wall 1a of the handle cover 1. A spherical fitting convex portion 9 protruding toward the back side is provided on the portion. Body cover 3
There is a handle cover 1 on the back side of the edge of the opening 3a at the end of the
along the outer peripheral edge of the side wall 1a, that is, the connecting portion 4
A plurality of spherical fitting recesses 10 (four in this embodiment) are provided facing the arm piece 8 of the motor fixture 7 along a circular arc centered on the rotation axis.
A fitting convex portion 9 of an arm piece 8 of the motor fixture 7 is inserted into a fitting recess 10 at the base of the main body cover 3 in a freely fitting and removable manner.

Next, the operation of the hair dryer A of the above embodiment configured as described above will be explained. Fig. 6 shows the handle cover 1 and main body cover 3 in a state where they are expanded to the maximum extent.You can use them as they are, or you can rotate the handle cover 1 in the direction of arrow A since there are multiple fitting recesses 10. The fitting protrusion 9 is inserted into one of the fitting recesses 10 so that it can be moved to a convenient angle. When the use is finished, rotate the handle cover 1 further in the direction of arrow A, and
As shown in the figure, the fitting protrusion 9 is inserted into the leftmost fitting recess 10 in the figure, folded and stored in a compact state. In the figure, 19 is a discharge port. In addition, in the case of the present invention, for example, the end of the main body cover is made into a U-shape, the end of the handle cover is sandwiched between the ends of the main body cover, and both side walls of the end of the main body cover are connected to the end of the handle cover. Fit the ends of the handle cover into the openings on both sides to rotatably connect the end of the handle cover and the end of the main body cover, fix the motor to the side wall of the end of the main body cover using a motor fixture, and connect the end of the handle cover to the end of the main body cover. A fitting recess may be provided in the fitting recess, and a fitting convex portion provided on the arm piece of the motor fixture may be inserted into the fitting recess in a detachable manner.

As described above, in the present invention, an arm piece is integrally extended from a motor fixture that fixes the motor to one end of the handle cover or the main body cover, and a fitting convex portion is provided at the tip of this arm piece. , a plurality of fitting recesses are provided on the other end of either the handle cover or the main body cover, arranged in a circular arc centered on the rotation axis of the connecting portion, and the arm of the motor fixing device is inserted into these fitting recesses. The fitting convex part of the piece is inserted in a detachable manner so that the handle cover can be folded toward the main body cover, so when not in use, the handle cover and main body cover can be folded to make it compact. When in use, the handle cover and main body cover can be rotated to make a convenient angle for use. Furthermore, since the motor fixture is also used as a folding mechanism component, the number of parts can be reduced, thereby reducing costs and facilitating assembly. Moreover, since the fitting protrusion of the arm piece extending from the motor fixing device is removably inserted into the fitting recess formed in the handle cover or main body cover, the fitting protrusion is elastically inserted into the fitting recess. It is possible to apply vibration to the handle cover or main body cover when inserting the hair dryer, and as a result, dirt attached to the suction port, etc. that sucks the air of the hair dryer can be removed by the folding operation, and the suction port, etc. can be removed from clogging. This enables safe long-term use.
