Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hair drier equipped with a means for preventing relatively long hair such as hair loss or broken hair that is sucked in with air from being wrapped around the shaft of a motor for driving a fan. It is an improvement.

[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, and reduce the rotation of the motor or stop 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, the hair-wrapping pin has a structure in which the hair-wrapping pin rotates together with the blower fan, so that the hair entering from the suction port winds one end of the hair-wrapping pin around the hair-wrapping pin. At the same time, the other end may be entangled with the suction port side. In this case, the rotation of the motor may be reduced or stopped (locked) as in the case where hair is wrapped around the motor shaft. There is a problem that the purpose of the term cannot 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 devising 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, as shown in the illustrated example, between the suction port 3 in the main body case 1 and the blower fan 8 which is rotated by the drive of the motor 6, the blower fan 8 receives the action of the suctioned air flow and idles. The feature is that the impeller 10 that rotates around the shaft 17 is provided.

[0006]

[Action]

 When the blower fan 8 rotates, the impeller 10 is rotated by the suctioned airflow of the blower fan 8, and the hair H sucked together with the air into the suction port 3 is wound around the idle shaft 17 or the impeller 10 by this rotation. It is possible to prevent winding around the shaft 7 of the motor 6 in advance. In this case, since the impeller 10 is rotated by the intake airflow of the blower fan 8, even if the hair H may be wound around the idle shaft 17 and the rotation of the impeller 10 may be stopped, the blower fan 8 or the motor may be stopped. It has no effect on the rotation of the shaft 7 of 6.

[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 has a blowout port 2 at the front end and a suction port 3 at the rear end. 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.

An impeller chamber 11 for accommodating the impeller 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 in the central portion of the grill 13 and the inner central portion of the inlet grill 14 in the impeller chamber 11, respectively, and the idle shaft 17 is provided between the bearings 15 and 16. The impeller 10 is rotatably supported so as to be aligned with the extension line of the front side or to be parallel to the position near the extension line, and the impeller 10 is fixed on the idle shaft 17. The impeller 10 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 10 is rotated by the airflow sucked from the suction port 3 along with the rotation of the blower fan 8, the hair H sucked together with the air from the suction port 3 becomes the blower fan 8 and the motor. Before the shaft 6 of the motor 6 is reached, the impeller 10 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 a large number of hairs H wind around the impeller 10 or the idle shaft 17 and the rotation of the impeller 10 stops, the blower fan 8 and the motor 6 stop the rotation of the impeller 10. Since it continues to rotate without being affected by the above, it does not hinder the use of this dryer, and there is no risk of the motor 6 seizing.

The hair H wound around the impeller 10 or the idle shaft 17 is formed by making a part or the whole circumference of the outer peripheral wall of the impeller chamber 11 transparent so that it can be seen from the outside of the impeller chamber 11, or Visible through a number of holes 14a in the inlet grille 14. If the inside of the impeller chamber 11 is configured to be visible from the outside in this way, the rotation state of the impeller 10 can be easily confirmed from the outside, and the rotation of the impeller 10 may be stopped or rotated at a low speed. In this case, the user will be warned that the hair H is wrapped around.

The hair H wound around the impeller 10 or the idle shaft 17 is configured to open and close the impeller chamber 11 so that the hair H can be removed. As an opening / closing structure of the impeller chamber 11 in the illustrated example, a ring 19 is integrally connected to the outer peripheral end of the suction port grill 14, and the ring 19 is connected to the outer peripheral wall 1a at the rear end opening of the main body case 1 by bayonet connection. It is designed to be detachably joined. That is, as shown in FIG. 2 and FIG. 3, a plurality of engaging claws 20 are provided on the inner circumference of the ring 19 of the suction inlet grille 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. Shaped engaging grooves 21 corresponding to the number of engaging claws 20, and by inserting the inlet grill 14 together with the ring 19 from the rear of the outer peripheral wall 1a at the rear end of the opening of the main body case 1 and rotating it slightly. By this, the engaging claw 20 engages with the engaging groove 21 in a retaining manner, and when the suction port grill 14 is rotated together with the ring 19 in the direction opposite to the above-described rotation direction, it can be pulled out rearward. I am doing it. In this case, if the idle shaft 17 of the impeller 10 can be pulled out from the bearings 15 and 16, the hair H wrapped around these can be removed more easily.

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.

[0013]

[Effect of the device]

 According to the present invention, between the suction port 3 and the blower fan 8 in the main body case 1, the impeller 10 which rotates around the idle shaft 17 under the action of the suctioned air flow of the blower fan 8 is provided. Therefore, as the blower fan 8 rotates, the impeller 10 rotates by the suctioned air flow of the blower fan 8, and the hair H sucked into the suction port 3 together with the air moves to the impeller 10 and the idle shaft 17. Since it winds around, it can prevent winding around the shaft 7 of the motor 6 in advance. In particular, since the impeller 10 is rotated by the air flow sucked by the blower fan 8, even if the hair H is wound around the idle shaft 17 and the rotation of the impeller 10 is stopped, the blower blows air. The rotation of the fan 8 and the shaft 7 of the motor 6 is not affected at all, and it is advantageous that the rotation of the motor 6 can be prevented from being reduced and the rotation can be prevented.
