Description

Hair dryer {HAIR DRYER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dryer, and more particularly, to a hair dryer capable of simultaneously discharging hot air and cold air by sucking outside air to flow hot air and cold air through separate flow paths, .

Generally, a hair dryer is an electric appliance used for rapidly drying a wet hair by hot air generated by electricity, and for maintaining a constant style of hair styling and maintaining it constantly. As for the structure of a conventional hair dryer, There is provided a heating means to which a power source is applied and a constant heat is generated by inherent resistance according to an applied power source supply.

And, it is constituted of an overheating preventing means for preventing overheating due to heat generated in the heat generating means, and a blowing device for introducing outside air into the heat generating means and guiding to lead out by hot air.

Here, the heat generating means is formed by winding an iron-nichrome hot wire around the insulator having a cross shape several times from the front to the back several times. The insulator has heat resistance, acid resistance and alkali resistance, and is a defective conductor of heat and electricity. When the power is supplied through the terminal connected to the hot wire, a high temperature is generated.

In addition, the overheat preventing means is fixed to an intermediate portion of the iron-nichrome hot wire so that the heat is normally turned on, and then the heat is generated over a certain limit in the iron-nichrome hot wire, Respectively.

In such a hair dryer, power is applied through a terminal, and heat required for drying hair style or hair is generated in the iron-nichrome hot wire. When the blowing device is operated, heat is generated on the side of the iron- So that hot hair can be easily dried or hair styling can be performed.

In addition, when the iron-nichrome hot wire is overheated during the drying process of the hair, the bimetal is turned off to prevent the electric power from being cut off and the burn due to the overheating.

However, in such a hair dryer, when the outside air is sucked by the air blowing device and is fed by the heating means, the outside air is produced in the process of passing through the insulator that supports the hot wire, and when the outside air is sucked, There is a problem that noise is generated.

In addition, when hot air is discharged, there is a problem that excessive heat is generated due to the reason that the discharge amount of the cold air can not be controlled, thereby damaging the hair.

Although not shown in the drawing, the opening and closing members may be plates provided on the handle 100 to slide the first and second outside air inlet openings 110 and 120 in a sliding manner.

The opening and closing members may be slidable by a linear motor driven by a control signal of the controller 520.

Next, the operation of the hair dryer of the present invention constituted as described above will be described.

1 to 3, the controller can open the first and second outside air inflow ports 110 and 120 using the opening and closing members.

Accordingly, the outside air can flow into the first and second flow paths 210 and 220 through the first and second outside air inlet ports 110 and 120.

Then, the controller 520 transmits a driving signal to the fan module 310. [

In addition, the controller 520 uses the power supply 510 to apply power to the heating coil 320.

The fan module 310 rotates the fan 311 at a constant rotation speed while being disposed on the first flow path 210.

Accordingly, the outside air flowing through the first outside air inlet 110 can be forced to flow along the first flow path 210 by the rotation of the fan 311.

Meanwhile, the heating coil 320 supplied with power is heated to a predetermined temperature.

Accordingly, the outside air forcibly flowing along the first flow path 210 is exposed to the heating coil 320, which is heated while passing through the heating coil 320, and the outside air is heated to flow at a predetermined temperature.

The heated outside air can flow in a circular shape through the first discharge body 410.

The outside air heated through the first discharge hole 411 formed at the end of the first discharge body 410 is discharged to one side of the discharge portion body 401.

At the same time, the outside air flowing through the second outside air inlet 120 flows along the second flow path 220, and the outside air flowing along the second flow path 220 flows along the second discharging body 420 .

Then, the outside air is discharged to the outside through the second discharge hole 421 formed at the end of the second discharge body 420 without being heated.

The end of the first discharge body 410 is disposed behind the discharge body 401 rather than the end of the second discharge body 420.

Therefore, the heating air outside the first discharge hole 411 and the second discharge hole 421, which are different from each other in position, are discharged through the first discharge hole 411 and the second discharge hole 421 A difference in air pressure is formed between the unheated ambient air discharged through the air outlet.

As a result, the outside air discharged through the first and second discharge holes 411 and 421 can form a constant flow rate toward the front of the discharge unit body 401.

Accordingly, in the present invention, when a hair dryer is used, hot air or cold air can be efficiently used by flowing the heated outdoor air and the unheated outdoor air through independent flow paths, and when hot air is used, It is possible to solve the problem that the temperature rises under the above-mentioned temperature range.

Meanwhile, the discharging part 400 of the present invention may be detachable from the upper end of the handle 100.

A hook type coupling system of a detachment type can be applied. In such a case, it may be required to provide a sealing member (not shown) therebetween to prevent leakage of outside air.

The discharge unit 400 according to the present invention is horizontally rotated at the upper end of the handle 100. The discharge unit 400 is driven by a control signal from the controller 520 to rotate the discharge unit 400 Hour) can be used.

In the embodiment of the present invention, the outdoor air is sucked and the hot air and the cold air are flowed through separate flow paths to form a flow velocity with a difference in atmospheric pressure, so that hot air and cold air can be simultaneously discharged.

Further, in the embodiment of the present invention, by using the ring-shaped discharging portion, discharging the heated outside air from the inside of the non-heated outside air, and forming the flow velocity by the difference in air pressure therebetween, have.
