[Industrial applications]

 The present invention relates to a hair dryer equipped with a means for preventing relatively long hair such as hair loss or broken hair that is sucked in with air from wrapping around a shaft of a motor for driving a fan, and improves the hair wrap prevention means. It was done.

[0002]

[Prior art]

 As a hair dryer provided with this kind of hair wrapping preventing means, for example, as disclosed in Japanese Utility Model Publication No. 61-24162, a hair dryer is used for wrapping hair from a rotation center portion of a blower fan fixed on a shaft of a motor. The pin is projected toward the suction port, and the hair entering from the suction port is wrapped around the hair wrapping pin to prevent the hair from wrapping around the motor shaft, thereby reducing the rotation of the motor or stopping it. There are some that are intended to prevent it.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, since the thin pin is used as the hair winding means, it is not possible to catch the hair sucked in near the inner peripheral wall forming the air passage, and the hair is wound around the motor shaft as it is. However, there was a problem that the intended purpose could not be fully achieved.

An object of the present invention is to provide a hair dryer having a hair wrapping means between the suction port in the main body case and the blower fan as described above, by improving the hair wrapping means. The point is to prevent the rotation of the car from slowing down or stopping.

[0005]

[Means for Solving the Problems]

 In the hair dryer of the present invention, the rotating body 10 which rotates around the rotating shaft 17 is arranged between the suction port 3 in the main body case 1 and the blower fan 8, and the outer diameter of the rotating body 10 and the rotating body 10 It is characterized in that the inner peripheral wall 25 forming the air passage located on the outer periphery of the is close to each other.

[0006]

[Action]

 By rotating the rotating body 10 together with the fan 8 in a state where the rotating body 10 and the inner peripheral wall forming the air passage are in close proximity, even hair passing through near the inner peripheral wall 25 can be reliably captured. .

[0007]

【Example】

 An embodiment of a hair dryer according to the present invention will be described with reference to the drawings. In FIG. 1, the main body case 1 is formed in a tubular shape that is long in the front-rear direction, and a blowout port 2 is formed at the front end thereof and a suction port 3 is formed at the rear end thereof. Between the air outlet 2 and the air inlet 3 in the main body case 1, a heating device 5 including a heater 4 and a blower device 9 including a motor 6 and a blower fan 8 fixed on a shaft 7 of the motor 6 are arranged in front and rear. And store it. When the motor 6 is driven, the blower fan 8 rotates, sucks air from the suction port 3 and heats it by the heat generating device 5, or blows warm air or cold air from the blowout port 2 without heating.

A rotary body 10 that rotates around a rotary shaft 17 is disposed between the suction port 3 and the blower fan 8 in the main body case 1. The outer diameter of the rotating body 10 is close to the inner peripheral wall (in the embodiment, the inner peripheral wall 25 of the fan casing 26) forming the air passage located on the outer periphery of the rotating body 10. Therefore, it is possible to reliably capture the hair that has entered through the suction port 3 and is about to pass through near the inner peripheral wall forming the air passage. The rotating shaft 17 is supported on an extension of the shaft 7 of the blower fan 8. As will be described later, the rotating shaft 17 may be unsupported so as to be free to rotate, or may be directly supported by the shaft 7 so as to be connected thereto. In the case where the rotary shaft 17 is directly connected to the shaft 7 to rotate the rotary body 10, various shapes of the rotary body 10 are conceivable. For example, a pin-shaped body projecting in a direction orthogonal to the rotary shaft 17 may be used. Alternatively, if the locus of the rotating body 10 at the time of rotation is substantially the same as the cross section of the air flow passage, it may be a single pin-shaped one. The outer diameter of the rotating body 10 includes the outer diameter of the rotating body 10 during rotation. Here, an embodiment will be described in which an impeller is adopted as the rotating body 10 and a rotary shaft 17 of the impeller is supported in a free-running state.

An impeller chamber 11 for accommodating an impeller as a rotating body 10 is formed between the suction port 3 in the main body case 1 and the blower fan 8. The impeller chamber 11 and the blower fan 8 are partitioned by a grill 13 made of punching metal or a mesh plate, and the suction port 3 is covered by a suction port grill 14. Further, front and rear bearings 15 and 16 are provided at the center of the grill 13 and the center of the suction grill 14 in the impeller chamber 11, respectively. The idle shaft 17 is provided between the bearings 15 and 16. The idler is supported so as to be idle so as to be in line with the front extension line or in the vicinity thereof, and the impeller is fixed on the idle shaft 17. The impeller is formed in a blade shape that rotates around the idle shaft 17 while receiving the action of the air flow sucked from the suction port 3 as the blower fan 8 rotates.

Therefore, when the impeller rotates due to the rotation of the blower fan 8 by the air flow sucked from the suction port 3, the hair H sucked together with the air from the suction port 3 is generated by the blower fan 8 and the motor 6. Before reaching the shaft 7, the impeller or the idle shaft 17 is forcibly wound around the shaft 7 so that the shaft 7 of the motor 6 is not wound around. At this time, even if many hairs H wind around the impeller or the idle shaft 17 and the rotation of the impeller stops, the blower fan 8 and the motor 6 have no influence on the stop of the rotation of the impeller. Since it continues to rotate without being damaged, it does not hinder the use of this dryer, and there is no risk of the motor 6 burning.

The hair H wound around the impeller or the idle shaft 17 may be formed by forming a part or all of the outer peripheral wall of the impeller chamber 11 into a transparent body so that the hair H can be easily seen from the outside of the impeller chamber 11. Visible through a number of holes 14a in the inlet grille 14. In this way, if the inside of the impeller chamber 11 is configured to be visible from the outside, the rotation state of the impeller can be easily confirmed from the outside, and if the rotation of the impeller is stopped or is rotating at a low speed. , The user is warned that the hair H is wrapped around.

The hair H wound around the impeller or the idle shaft 17 is configured so that the impeller chamber 11 can be opened and closed so that the hair H can be removed. As the opening / closing structure of the impeller chamber 11 of the illustrated example, a ring 19 is integrally connected to the outer peripheral end of the inlet grill 14, and the ring 19 is connected to the outer peripheral wall 1a at the rear end of the opening of the main body case 1 with a bayonet. It is designed to be removably attached by. That is, as shown in FIGS. 2 and 3, a plurality of engaging claws 20 are provided on the inner circumference of the ring 19 of the suction inlet grill 14, and the outer peripheral wall 1a at the rear end of the opening of the main body case 1 is L-shaped in plan view. Of the engaging grooves 21 are formed in accordance with the number of the engaging claws 20, and thus the suction inlet grille 14 is inserted together with the ring 19 into the outer peripheral wall 1a at the rear end of the opening of the main body case 1 and is rotated slightly. As a result, the engaging claw 20 engages with the engaging groove 21 in a retaining manner, and when the suction inlet grill 14 is rotated together with the ring 19 in the direction opposite to the rotating direction, it can be pulled out rearward. There is. In this case, if the idle shaft 17 of the impeller can be pulled out from the bearings 15 and 16, it becomes easier to remove the hair H wound around them.

The impeller chamber 11 does not necessarily have to be openable and closable. Further, the grill 13 that separates the impeller chamber 11 and the blower fan may be omitted.
