Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to a hair dryer having a suction port provided with a filter to prevent hair from being sucked in.

<Prior art> Conventional hair dryers in which a filter is provided at the suction port to prevent hair from being sucked in include ribs provided at several locations on the suction port to form a filter, or wire mesh filters made of wire mesh, or resin. A resin filter formed using the above method is installed.

As mentioned above, in the case where the air inlet is provided with several ribs to form a filter, the wire mesh filter, or the resin filter is installed, the porosity is as low as 70% or less, and the air suction efficiency is poor. In the case where a filter or resin filter is installed at the suction port, the strength of the suction port is weak, and several reinforcing ribs must be provided separately. As the air flow rate decreased, the air flow at the intake port became turbulent, causing noise.

<Purpose of the invention> The object of the invention is to obtain a hair dryer that eliminates the above-mentioned drawbacks.

<Embodiment of the invention> An embodiment of the hair dryer of the invention will be described below with reference to the drawings.

The hair dryer of the present invention has a main body 3 formed by a front main body 1 and a rear main body 2, and a ventilation passage 4 of the front main body 1.
A heat generating assembly 5 such as a heater is disposed at the air outlet 6 of the air blowing passage 4, and an air outlet body 8 having a large number of through holes 7 is disposed at the air outlet 6 of the air passage 4. A switch 11 having a terminal 10 is provided, one side of a power cord 13 having a cord bushing 12 attached thereto is connected to the switch 11, and a predetermined connection terminal of the heat generating assembly 5 is connected by a lead wire 14. Then, connect the power cord 13 to the other predetermined connection terminal of the heat generating assembly 5, and attach the cord bushing 12 of the power cord 13 to the bushing attachment part 15 of the front handle part 9 of the front body 1, A motor 18, a motor mounting base 19, and a blower fan 20 are installed in the blower passage 17 of the rear body 2, which communicates with the blower passage 4 of the front body 1 when attached to the front body 1.
A rectifying fin frame 25 of a rectifying fin 24 formed of an aluminum core 23 having a large number of through holes 22 is installed around the motor mounting base 19 of the air blower assembly 21 consisting of the above-mentioned rear main body 2. Ventilation passage 17
A filter frame 30 comprising a filter 29 formed of an aluminum core 28 having a large number of through holes 27 is attached to the air intake port 26 of the air blower assembly 21, and a lead wire 32 is connected to one motor terminal 31 of the motor 18 of the air blower assembly 21.
The switch 11 is connected via the lead wire 3 to the other motor terminal 33 of the motor 18.
5 to connect the predetermined connection terminal of the heat generating assembly 5 to the front body 1 and connect the rear body 2 to the front body 1.
The engagement concave portion 37 of the rear body 2 is engaged with the engagement convex portion 36 of the rear body 2, and the rear handle portion 40 of the rear body 2 is engaged with the threaded portion 39 of the boss 38 of the front handle portion 9 of the front body 1.
The screw 42 is inserted through the boss portion 41 and screwed into the threaded portion 39, and the screw 42 is inserted into the screw portion 39.
2 is tightened and installed.

In addition, in the above configuration, the air blower assembly 2 of the rear body 2
1, especially the motor 18 with the screw 4 as shown in FIG.
5 to the motor mounting base 19, and the blower fan 20 is attached to the motor shaft 46 of the motor 18 via a joint 47 with a nut 48. The filter frame 30 to which the filter 29 is attached is particularly As shown in FIG.
and an engagement recess 50 that engages with the engagement protrusion 49.
is provided at the intake port 26 of the ventilation passage 17 of the rear body 2, and the filter frame 30 is detachably attached to the intake port 26, and the aluminum core 2 forming the rectifying fins 24 and the filter 29 is provided.
Reference numerals 3 and 28 are formed by forming aluminum foil with a thin foil thickness of 25 μm to 75 μm into a honeycomb shape.

The hair dryer configured as described above can be operated by turning on the switch 11 and then turning on the heat generating assembly 5 and the blowing assembly 2.
1 is energized, outside air is sucked in by the fan 20 of the blower assembly 21 through the filter 29 of the intake port 26, heated by the heat generating assembly 5 of the blower passage 4 through the rectifying fins 24 of the blower passage 17, and then heated by the heat generating assembly 5 of the blower passage 4. It is used by discharging from 6.

In the above case, the filter 29 reliably removes dust, hair, etc. contained in the outside air, and since the filter 29 is formed of an aluminum core 28, it has a rectifying effect at the intake port 26 and reduces noise caused by wind noise. can be reduced. Also, the rectifier fin 2
4 is also formed of an aluminum core 23, so the vibration in the radial direction of the motor 18 can be absorbed by the aluminum core 23, and the vibration can be reduced, and the air is rectified by the aluminum core 23, so that turbulence does not occur. Air can flow efficiently and noise can be reduced.

<Effects of the invention> Since the hair dryer of the invention has the above-mentioned configuration, the porosity of the filter can be improved to 95% to 99%, and the air suction efficiency is good, and the intake port is reinforced. Moreover, the air flow is not disturbed at the suction port, and noise can be reduced.
