Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dryer used for drying and setting hair.

[0002]

2. Description of the Related Art In a conventional hair dryer, as shown in FIG. 10, a suction port 1A of a hair dryer body A is
The openings 1B are formed by forming ribs in a grid pattern at intervals, and a filter portion 3 having a smaller opening area than the openings 1B and forming a large number of holes 3B outside the suction port 1A.
A is provided. Garbage in this filter section 3A,
It prevents the ingress of dust and hair.

Further, in the hair dryer shown in FIG. 11, the suction opening 1A of the hair dryer main body A is formed with a mesh-shaped opening 1B, and this suction opening 1A is formed.
It is also considered that an intermediate filter portion 3C having a smaller opening area than the opening portion 1B is fixedly provided inside the fan and with the fan 2A. The suction port 1A prevents large dust and dirt from entering, and the intermediate filter portion 3C prevents dust, dirt, and hair smaller than that.

As described above, it is more effective to perform the two steps in order to prevent the invasion of dust, dust and hair, because of the burnout of the heater and the winding around the motor shaft due to the intrusion of dust, dust and hair. It is possible to prevent the heater from overheating due to the stop of the motor.

[0005]

In the former hair dryer, the air sucked by the fan 2A driven by the motor and blown to the discharge port is the filter portion 3A.
Dust, dust, hair and the like are first captured by the filter unit 3A, then captured by the suction port 1A, and those that cannot be completely captured enter the inside of the hair dryer body A. In this case, in order to prevent dust, dust, hair, etc. from entering the hair dryer main body A, the filter portion 3A and the opening 1 of the suction port 1A are provided.
By reducing the area of the opening portion of B, dust, dust, hair, etc. can be captured. Further, even if dust, dust, hair or the like passes through the filter portion 3A, it can be caught by the suction port 1A. However, the suction port 1A
If the opening area of the opening 1B is reduced, the amount of air taken in decreases, and the amount of air blown (air amount) decreases.
On the other hand, in order to secure the temperature of hot air and the amount of blown air more than a predetermined amount, it is necessary to set the amount of air more than a predetermined amount, and the opening area of the filter portion 3A and the opening portion 1B of the suction port 1A is naturally determined. Therefore, it was impossible to reduce the opening area.

In the latter hair dryer, the probability of catching dust, dust, hair and the like is inevitably increased due to the presence of the intermediate filter portion 3C, but the opening area of the intermediate filter portion 3C is smaller than that of the suction port 1A. , The air volume is reduced,
In order to secure a predetermined air volume, it is necessary to take measures such as increasing the output of the motor, which leads to an increase in cost.

The object of the present invention has been made in view of the above points, and it is possible to remove dust and dust without reducing the air flow rate (air volume).
The present invention provides a hair dryer that can efficiently capture dust, hair, and the like.

[0008]

SUMMARY OF THE INVENTION The present invention is a hair dryer, wherein a filter section is provided between the suction port of the hair dryer body and the fan of the blower section, and the opening area of this filter section is the suction port. The opening area of the filter is larger than the opening area of the fan, and the filter is rotated in conjunction with the rotation of the fan, and a plurality of ribs are projectingly provided on the filter. It can be freely attached to and detached from.

[0009]

According to the structure of the hair dryer of the present invention, dust, dust, hair, etc. are disposed in the filter section which is disposed between the suction port and the fan of the air blow section and rotates in conjunction with the rotation of the fan. It can be captured efficiently.
