Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a portable thin hair dryer.

[Background technology] In the conventional hair dryer A' of this type,
As shown in FIG. 10 (Japanese Unexamined Patent Publication No. 58-149705), a flat plate-shaped discharge outlet cover 11' is provided at the hot air outlet on the front end face of the dryer main body 6, so that the hot air can pass through the hot air outlet. Discharge hole 3 of cover 11'
The hot air that blows out from 1 does not spread out and only blows out in a straight line, making it impossible to dry a wide area.
It wasn't functional.

[Object of the Invention] The present invention has been made in view of the above circumstances, and its purpose is to provide a portable and thin hair dryer in which hot air is emitted from the outlet hole of the outlet cover through the outlet. The aim is to spread out the hot air that is used to dry the air, making it possible to dry a wide area, improving performance and functionality.

[Disclosure of the Invention] The hair dryer of the present invention includes a hot air discharge unit 6 of a dryer body 6 which accommodates a hot air generator B consisting of a blower fan 1, a heater 2, and a motor 3, and is provided with a hot air outlet 4 and an inlet 5. A cover body 30 which is a hair dryer with a discharge port cover provided at the outlet 4 and has an arc-shaped cross section that is vertically long and curved in the hot air blowing direction.
The discharge port cover 11 is formed by providing a plurality of discharge holes 31 vertically on the left and right sides of the discharge port cover 11, and the horizontal cross-sectional area of the vertical rib 32 at the center that partitions the left and right discharge holes 31 of the discharge port cover 11 is the hot air blowing area. The rear side is made larger than the front side in the direction, and with this configuration, the above object can be achieved. That is,
The hot air ejected from the discharge port cover 11 through the hot air discharge port 4 can be spread out by the discharge port cover 11 having an arcuate cross-section, thereby making it possible to dry a wide range.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The dryer main body 6 is divided into two parts and has a generally rectangular shape when viewed from the side, with opposing side walls 9 connected to a peripheral wall 10.
It is constructed by connecting. A suction port 5 is provided on the side wall 9, and a hot air discharge port 4 is provided on the front end surface of the peripheral wall 10.
As shown by the arrow in FIG. 2, the hot air outlet 4 is provided with an outlet cover 11 that extends vertically and has an arcuate cross section that is curved in the hot air blowing direction. The discharge port cover 11 is formed by providing a plurality of discharge holes 31 at the top and bottom on the left and right sides of a cover main body 30 that is elongated and has an arcuate cross section. As shown in FIG. 8, the horizontal cross-sectional shape of the central vertical rib 32 that partitions the left and right discharge holes 31 of the discharge port cover 11 is a triangle with a cross-sectional area larger on the rear side than on the front side in the hot air blowing direction. The hot air blowing out from the discharge hole 31 through the hot air discharge port 4 can be further diffused by the vertical ribs 32. still,
The horizontal cross-sectional shape of the vertical rib 32 may be rounded on both sides of the front end in the hot air blowing direction, as shown in FIG. 9, so that the cross-sectional area is larger on the rear side than on the front side in the hot air blowing direction. . A connector 12 is formed at the lower part of the discharge port cover 11 of the dryer body 6, and a plug 15 is removably attached to the connector 12 so as to protrude in a direction perpendicular to the hot air blowing direction to form the grip 8. There is. The connector 12 is integrally molded with the conductive plate 13, and the connector pin 14 is caulked and fixed to the connector 12 to bring the connector pin 14 and the conductive plate 13 into electrical continuity. The plug 15 is the insertion part 1 into the connector 12
The plug 15 is formed by integrally molding a plug body 17 and a bushing 18 having a plug pin 19 and a bushing 18, and the plug 15 is formed by caulking and fixing the plug pin 19 and the power cord 7, and molding the power cord 7 below the bushing 18. We are deriving it towards. Therefore,
When in use, the power cord 7 can be suspended from below the grip 8, and the grip 8 can be gripped smoothly, making it easy to use.
A locking groove 20 is formed on the outer periphery of the insertion portion 16, and a locking pin 22, which is horizontally biased by a spring 21 attached to the dryer body 6, is fitted into the locking groove 20 through the insertion hole 23 of the connector 12. I'm letting you do it. The locking groove 20 is inclined vertically, and the tip of the locking pin 22 biased by the spring 21 is tapered.
The fitting between the lock pin 22 and the lock pin 22 is a click mechanism. A flange 20 is provided on the outer periphery of the plug body 17, and this flange 29 prevents the grip 8 from slipping. Inside the dryer body 6, there are a blower fan 1, a heater 2 attached to a wiring board 26, and a motor 3.
It houses a hot air generator B consisting of, and
It houses a main switch 24 that turns on and off power to the hot air generator B, and a changeover switch 27 that adjusts the amount of air blown. The main switch 24 of this hair dryer A is activated by a switch cam 28 by vertical movement of a switch operation plate 25 provided at the bottom of the discharge port cover 11.
It is operated on and off through Switch operation board 2
5 is fitted with a spring portion 33 formed integrally with the discharge port cover 11 so that it can be moved up and down and stopped at a predetermined position, that is, a recess 34 of the spring portion 33. Further, the switch operation plate 25 is connected to the discharge port cover 11.
Since the cross section is arcuate to match the shape of the finger, it is easy to hold the finger even without any protrusions. In this way, the discharge port cover 11 has an arcuate cross section.
Since a switch operation section, a connector section, etc. are provided in a dead space at the bottom of the dryer body 6, the dryer main body 6 can be made compact.

[Effects of the Invention] The present invention is a hair dryer in which a discharge port cover is provided on the hot air discharge port of the dryer main body, and the cover main body is vertically long and has an arcuate cross section that is convex in the hot air blowing direction. A discharge port cover is formed by providing a plurality of discharge holes, and the horizontal cross-sectional shape of the central vertical rib that partitions the left and right discharge holes of the discharge port cover is such that the cross-sectional area is larger on the rear side than on the front side in the hot air blowing direction. Therefore, the hot air that blows out from the outlet cover through the hot air outlet can be guided by the cover body, which has an arcuate cross section, and be spread out as a whole.Moreover, the hot air that is spread by the cover body can be spread out in the horizontal section. The shape is diffused by vertical ribs whose cross-sectional area is larger on the rear side than on the front side in the hot air blowing direction, and therefore a wide range of drying can be performed, thus improving performance. functionality can be improved.
