Description

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

[Background technology]

Recently, many people carry hair dryers with them when traveling, and there is a desire for a small, ultra-thin, and compact hair dryer that can fit in a corner of a travel bag or even a pocket of clothing.

However, as shown in FIG. 1, in a conventional hair dryer, a handle part N protrudes from a main body case H that forms a discharge port A and a suction port B, and houses an air blower and a heat generating device inside. The power cord extends from the bottom end of the
When the hair dryer is not in use, such as when traveling, the power cord (E) is wrapped around the handle part (D) for storage, so the handle part (D) protrudes from the main body case (H), and when the power cord (E) is wrapped around the handle part (D). The problem with this was that the power cord was bent excessively at the cord outlet (X in FIG. 1), causing the wire to break at this point.

In addition, as shown in Utility Model Publication No. 45-14013,
It has been proposed to reduce the size of the main body case by forming the main body case with a pair of side walls and a substantially cylindrical peripheral wall and using the main case itself as a handle part, thereby eliminating the protruding handle part. Since the case is thin, it is not possible to wrap the power cord around the outer circumference of the surrounding wall and lock it, so when carrying it, the power cord must be wrapped around the side wall, which makes the power cord bulky and large. Since they extend in perpendicular directions, there is a problem in that when the power cord is wound, the power cord is bent excessively at the outlet, making it easy to break at this portion.

Furthermore, as shown in Utility Model Application Publication No. 53-20679,
Some hair dryers are equipped with a cord reel in the main case to wrap and store the power cord, but since the cord reel is installed on the outer side wall of the main case, the thickness of the hair dryer becomes large, making it difficult to carry when traveling. It is large and inconvenient, and when it is used, the power cord is pulled out in a direction perpendicular to the surrounding wall, so the power cord is extremely prone to bending at the outlet during use. There was a problem that parts were easily disconnected.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a hair dryer that is small and convenient to carry and that reduces the possibility of disconnection of the power cord.

[Disclosure of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3 of the drawings. The main case is composed of a pair of side walls 1, 1 arranged to face each other and a circumferential wall 11 connecting these side walls, and the outer circumferential edges of the pair of side walls 1, 1 protrude outward beyond the outer surface of the circumferential wall 11. , the power cord 9 is wrapped around the outer surface of the peripheral wall 11 for storage, and there is a ventilation chamber A inside the main body case.
A ventilation room B and a switch storage room C are provided.
The air blowing chamber A has a peripheral wall 11 forming it in a substantially cylindrical shape, an opening 5 for discharging air in a part of the peripheral wall 11, and a suction port 2 in the side wall 1.
A centrifugal fan 4 with a motor 3 disposed in the center is housed in the ventilation chamber A. The ventilation chamber B communicates with the opening 5 of the ventilation chamber A on one side, has a discharge port 6 on the other side, and has a heating element 7 disposed therein. Furthermore, the switch storage chamber C is installed in front of the ventilation chamber A in parallel with the ventilation chamber B, and has a power supply opening/closing and hot/cold air selection switch 8 inside.
It accommodates. Reference numeral 9 denotes a power cord extending from the switch storage chamber C along the outer surface of the circumferential wall of the substantially cylindrical ventilation chamber A in a tangential direction thereof, and supplies power to the motor 3 and the heating element 7 via the switch 8. Also,
The outer periphery of the attachment part of the power cord 9 is covered with a bushing 10 made of an elastic material such as rubber in order to prevent the power cord 9 from breaking due to extreme bending. The power cord 9 is inserted more inwardly than the power cord 9, so that the power cord 9 can be easily stored.

When using the hair dryer, grip the side wall 1 or the peripheral wall 11 of the main body case with your fingers, and when not in use, connect the power cord 9 to the outer periphery of the peripheral wall 11 as shown in Figure 2. It is wrapped around it.

〔Effect of the invention〕

As described above, the present invention comprises a main body case composed of a pair of side walls arranged to face each other and a peripheral wall connecting these side walls, and a blowing chamber for accommodating a motor and a centrifugal fan is provided in the main body case. A hair dryer is provided with a ventilation chamber for accommodating a heating element and a switch storage chamber for accommodating a switch at the front in the air blowing direction of the ventilation chamber, and a power cord is extended from the peripheral wall, and the outer periphery of the pair of side walls is The peripheral wall protruding outward from the outer surface of the peripheral wall and forming the ventilation chamber is formed into a substantially cylindrical shape, and the power cord extends from the switch storage chamber along the outer surface of the cylindrical peripheral wall and in a tangential direction thereof. Therefore, by wrapping the power cord around the outer circumference of the surrounding wall and locking it, the hair dryer becomes thinner and more convenient to carry.
Furthermore, the power cord extends from the switch storage chamber provided in front of the ventilation chamber along the outer surface of the cylindrical peripheral wall that constitutes the ventilation chamber and in the tangential direction thereof, so that the power cord can be easily connected not only during use but also when carried. Even when wrapped around the main body case, there are no parts that bend excessively, which reduces the chance of wire breakage.
