い。 Conventional hair dryers usually take in air from the rear of the main body case, heat it with a heating element, and blow it out in a straight line forward as hot air. In this case, since the air passes through the heating element only once, the temperature of the hot air is likely to be influenced by the temperature of the indoor air. Furthermore, some of the heat from the heating element is transferred to the main body case by radiation and radiated to the outside, which poses a problem in terms of thermal efficiency, and the main body case is heated, which is undesirable from a safety point of view.

題がある。 Conventionally, as shown in Japanese Patent Application Laid-open No. 54-10059, for example, a bowl-shaped surface is formed at the front of the main body case, an air outlet is formed around this bowl-shaped surface, and a return flow is provided at the center. It has been proposed that a part of the hot air blown out from the outlet is sucked in again from the reflux inlet and reused.
In such a device, the air passes through the heating element only once, and as mentioned above, there is also a problem in terms of thermal efficiency.

たものである。 The present invention provides a partition tube made of a good thermal conductor in the cylindrical main body case, forms an annular intake passage around the outer periphery of the partition tube, and a hot air passage concentrically within the partition tube. The intake port and the outlet of the hot air passage are formed on the same plane at the tip of the main body case, a heating element is disposed within the hot air passage, and a fan is provided between the rear ends of the intake passage and the hot air passage. It is something.
以下、本発明の一実施例を図面を参照して説明

端部間に臨ませたフアン８を取付ける。 Reference numeral 1 indicates a hair dryer, in which a cylindrical partition tube 2 made of a good heat conductor such as aluminum and opened at both ends is placed inside a cylindrical main body case 9 made of synthetic resin.
An annular intake passage 3 is provided on the outer periphery of this partition tube 2.
A hot air passage 4 is formed concentrically within the partition tube 2, and an intake port 5 of this intake passage 3 and a hot air passage 4 are formed concentrically within the partition tube 2.
A lattice-shaped outlet 6 is formed on the same surface at the tip of the main body case 9, and a heating element 7 is disposed within the hot air passage 4. Further, a motor 13 is attached to the rear part of the main body case 9 via a mounting bracket 14, and a fan 8 facing between the rear ends of the intake passage 3 and the hot air passage 4 is attached to the motor 13.

発熱体７の通電を制御する。 A handle part 10 is provided at the lower part of the main body case 9, and a switch 11 is attached to a switch attachment part 12 of the handle part 10. This switch 11 is
By this operation, energization of the motor 13 of the fan 8 and the heating element 7 is controlled.

２の熱を受けて予熱される。 In the above configuration, when the switch 11 is operated to drive the motor 13 to rotate the fan 8 and cause the heating element 7 to generate heat, the air is transferred to the intake port 5.
The air enters the air intake passage 3 in the main body case 9, changes its flow direction at the rear end, and is guided to the hot air passage 4, where it is heated by the heating element 7 and blown out from the air outlet 6. At this time, a part of the hot air blown out hits the user's hair and bounces back, enters the intake passage 3 through the intake port 5 again, and is guided to the hot air passage 4. In this way, some hot air is transferred between the intake passage 3 and the hot air passage 4.
The whole is refluxed and reheated during this reflux. Particularly when hair is being styled, the air inlet 5 is close to the hair, which further promotes the circulation of hot air and improves thermal efficiency. Further, when the air to be taken in passes through the intake passage 3, it is preheated by receiving heat from the partition tube 2 made of a good thermal conductor.
そして、仕切筒２からの熱は吸気通路３を通る
空気によつてうばわれ、本体ケース９にはほとん
ど伝えられない。 The heat from the partition tube 2 is dissipated by the air passing through the intake passage 3 and is hardly transmitted to the main body case 9.
本発明によれば、空気は本体ケースの吸気口か

切筒を介して吸気通路の空気が予熱され、したが
つて、熱効率を十分に高めることができる。 According to the present invention, air is sucked in from the intake port of the main body case, passes through the intake passage, enters the hot air passage, is heated by the heating element, and is blown out as hot air from the air outlet. On the same plane, and
Since the air intake ports are concentrically opened around the air outlet, a portion of the hot air that is blown out hits the hair and bounces off, and is immediately sucked into the air intake port, where it is reheated in the hot air passage. Air in the intake passage is preheated through the partition tube made of a good conductor, and therefore thermal efficiency can be sufficiently increased.
また、熱風通路の外周に吸気通路が配置されて
いるため、仕切筒からの熱は吸込まれる空気によ
つてうばわれ、したがつて、本体ケースが高温に
加熱されることがなく、安全に使用することがで
きる。 In addition, since the intake passage is placed around the outer periphery of the hot air passage, the heat from the partition tube is dissipated by the air taken in, so the main body case is not heated to high temperatures and is safe. can be used.
