Description

Integrated Heating and Blowing Hair Dryer}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dryer, and more particularly, to a heat generating blower integrated hair dryer which can obtain air and heat at the same time by coating a heating element on a blade surface of a screw blower.

Hair dryers are electronic devices that generate heat and wind to dry out wet hair or to create a style for wet hair.

In general, a hair dryer is provided with a heater that generates heat by electricity and a fan connected to a motor for dissipating heat generated by the heater to the outside.

That is, while operating the fan, the air is introduced through the main body rear grill to form a flow, and the air flow is heated while passing through the heating heater, and then the hot wind contacts the hair through the main body front discharge grill. This will allow you to dry your wet hair or create the hairstyle you want.

Such a conventional hair dryer should have a sufficient space occupied by the heater for heating the air and the fan for blowing the heated air inside the main body of the hair dryer, and the hair dryer is made smaller by the space where the heater and the fan are installed. There was a problem that can not be manufactured in light weight.

In addition, when the fan is rotated by a motor and air is blown by a heater, the air is subjected to resistance due to the heater, and the air resistance inevitably increases the fan noise as the power consumption increases in the motor.

In general, a heater using electricity as a heat source generally uses a nichrome wire alloyed with nickel and chromium as a heating element, and since such a nichrome wire type heater is composed of one element as an electric circuit, As a result, the thinning phenomenon occurs due to the oxidation reaction, and the change of the resistance causes the property of the heating element to be changed, thereby degrading the precision of temperature control, shortening the life and partially shorting it during use, which can cause the entire heater to lose its function as well as overheating. There was a problem that may occur due to a fire accident.

In addition, since the heater is made of a thin wire in the form of a coil of nichrome wire as described above, there is a problem that there is a limit in transferring heat generated from the heater to the air effectively because the surface which is in direct contact with air is not wide. In order to increase the temperature of the heater excessively, if the central temperature of the heater itself is excessively increased than the temperature of the air discharged through the heater there is a problem causing a safety accident due to overheating.

In addition, the fan located inside the hair dryer has a small size, so in order to supply air of sufficient flow rate to the heater by the fan, the fan must be rotated at a high speed, which inevitably causes a fan noise when using the hair dryer. there was.

The problem of the present invention devised to solve the above-mentioned problems is that the heat generation and blowing are integrally constructed, the structure is simple, and the air is contacted to increase the area of heat generated by increasing the contact time to effectively air at low power The present invention provides a hair dryer integrated with a heating fan capable of generating heat.

In addition, an additional object of the present invention is to provide a heat generating blower integrated hair dryer capable of blowing a large amount of air even when the blade is rotated at a low speed due to the blade having a large area installed in the direction in which air is blown.

In addition, an additional object of the present invention is to provide a heat blowing air-integrated hair dryer which can prevent breakage of a heat generating portion that may be caused by a difference between a thermal expansion coefficient of an existing heating line and a base in which a heating line is installed. have.

In addition, an additional object of the present invention is to provide a heat blowing air-integrated hair dryer that can emit a large amount of far-infrared rays and improve the user's hair health.

1 to 3 is a conceptual diagram schematically shown to explain a heat generating air integrated hair dryer according to an embodiment of the present invention,
Figure 4 is a schematic diagram schematically illustrating a heat generating air integrated hair dryer according to another embodiment of the present invention.

Hereinafter, a preferred embodiment of a heat generating air integrated hair dryer according to the present invention will be described in detail.

1 to 3 is a schematic diagram schematically illustrating a heat generating air integrated hair dryer according to an embodiment of the present invention. 1 to 3, the heating fan integrated hair dryer according to a preferred embodiment of the present invention, the rotary shaft 200, motor (M) (not shown), body 300, screw blade 400 and heat generation It is composed of a component including a portion 410, which will be described in detail below.

First, the hair dryer according to the present invention basically has a housing 100 in which discharge holes 120 and intake holes 110 are formed in front and rear, respectively, so that air flows, and the housing 100 through the intake holes 110. When the external air is forced into the interior, the air is forced into the housing 100 is heated is made of a general configuration of the hair dryer in the general manner forcibly discharged to the outside through the discharge hole (120).

Here, the rotating shaft 200 is installed in the housing 100, both ends are installed in the longitudinal direction of the housing 100, that is, the intake hole 110 and the discharge hole 120, respectively.

In addition, a motor (M) (not shown) is installed on the rotating shaft 200 to rotate the rotating shaft 200 indefinitely.

The body 300 is located inside the housing 100 and is installed in the longitudinal direction of the rotation shaft 200. At this time, the body 300 is made of a hollow tube shape in the longitudinal direction, the motor (M) (not shown) is accommodated therein, the body 300 is rotated by the rotary shaft (200).

The screw blade 400 is formed to be arranged in a plurality in the outer diameter of the body 300, are located at regular intervals along the longitudinal direction of the body 300.

That is, the screw blade 400 formed on the outer diameter of the body 300 serves as a wing of the conventional hair dryer blowing fan for blowing, the length of the body 300 installed in the front and rear direction of the rotary shaft 200 It is formed long in the front and rear direction on the outer diameter surface.

At this time, the screw blade 400 is made of a continuous screw form, not a general linear wing, so that air can stay between the screw blade 400 for more time, as in the heat generating section 410 to be described later It has the effect of increasing the exothermic effect.

The heat generating part 410 is formed on the outer surface of the screw blade 400. Here, the heat generating unit 410 is composed of a lower base 411, a ceramic insulating layer 412, a heating pattern layer 413 and a lead wire 414, which will be described in detail as follows.

The lower base 411 is made of metal such as stainless steel (SUS) or aluminum having a thickness of about 0.5 to 1.5 mm, and a ceramic insulator is thinly coated on the upper surface of the lower base 411 several times to form a ceramic insulating layer ( 412 is formed, and the heating pattern layer 413 is printed on the upper surface of the lower base 411 on which the ceramic insulating layer 412 is formed.

In this case, the heating pattern layer 413 is preferably a ruthenium oxide (Ru02) -based material formed in a line shape (see FIG. 3).

In addition, both ends of the heating pattern layer 413 are connected to a predetermined lead wire 414 to receive power.

The heating part 410 may further include a predetermined protective layer 415 on the upper surface of the heating pattern layer 413. In this case, an additional protective layer 415 may be further selectively formed on the protective layer 415, such that the ceramic insulating layer 412, the heating pattern layer 413, the lead wire 414, and the protective layer ( 415) as a whole.

The heat generating part 410 has a structure in which a heat generating pattern layer 413 of ruthenium oxide (Ru02) -based material is printed on the lower base 411, and thus the lower base 411 and the ceramic insulating layer ( The difference in thermal expansion coefficient between the 412 and the difference in thermal expansion coefficient between the ceramic insulating layer 412 and the heating pattern layer 413 can be minimized.

That is, when the heat generating part 410 rises rapidly to a high temperature, the heat generating part 410 may be prevented from being damaged due to a difference in thermal expansion coefficient between the respective components.

Therefore, it is safe even if the temperature of the heat generating part 410 rises sharply, and since the structure of the heat generating part 410 is a surface heating element, more uniform heat generation is possible, and the shape of the heat generating part 410 varies. The advantage is that there is no restriction in the form of change.

In addition, the ceramic insulating layer 412 is made of a ceramic material that emits far infrared rays, thereby improving the hair health of the user.

In this case, a reflection surface 130 may be further formed on the inner diameter surface of the housing 100 to allow the far infrared rays emitted from the ceramic insulating layer 412 to be reflected and emitted through the discharge hole 120.

In addition, the heat generating unit 410 may be selectively formed on one surface or both surfaces of the screw blade 400.

In the present invention, the heating fan integrated hair dryer is installed in the housing 100, and the screw blade 400 having the heating portion 410 is formed on the outer diameter surface while accommodating the motor M (not shown) therein. The formed body 300 rotates about the rotation shaft 200.

When cold outside air is forced to the inside of the housing 100 through the intake hole 110 of the rear of the housing 100 by the rotating body 300, the heat generating portion formed in the screw blade 400 ( At the same time as the air is generated by the 410 and the screw blades installed on the outer diameter surface of the rotating body 300, the heated air is discharged to the front discharge hole 120 of the housing 100 and transferred to the user's hair. Will be.

At the same time, when the far infrared rays are emitted by the ceramic heat transfer layer of the heat generating unit 410, the far infrared rays are reflected on the reflecting surface 130 of the inner diameter surface of the housing 100 and transmitted to the user's hair through the discharge hole 120. .

This is the heat generated in the surface of the screw blade 400 at the same time it is blown in contact with the screw blade 400 made of a wide surface formed on the outer diameter surface of the body 300 is rotated outside the cold air flowing into the hair dryer Heating by the unit 410 has the advantage that the heating efficiency is significantly higher than the conventional coil type heater.

In addition, since the heat generating part 410 of the present invention is directly implemented on the lower base 411 made of a metal material such as SUS or aluminum, there is little thermal resistance, so that the temperature difference between the temperature of the finally generated air and the heat generating part 410 is reduced. Since the maximum temperature of the heat generating unit 410 is similar to the air temperature (about 200 ° C.) even though the user obtains the desired air temperature, there is no local overheating of the heat generating unit 410. There is no possibility of a safety accident due to overheating, there is no burning odor due to the local high temperature of the existing hair dryer has the advantage that the user can use safely and comfortably.

In addition, the body 300 and the screw blade 400 formed on the outer diameter surface of the body 300 in the present invention is integrally configured to perform the blowing and heating at the same time, the screw blade required for blowing It is possible to widen the wing area of the motor, and in addition, since the motor M (not shown) is accommodated inside the long tubular body 300, an optional large motor M (not shown) can be easily installed. And replaceable, allowing more air to be blown with less rotation.

Therefore, due to the low speed, the blowing noise is low, the blowing blades themselves are in the form of a screw has the advantage of less noise generation than the blowing fan of the conventional general hair dryer.

On the other hand, the hair dryer of the present invention has a very high emissivity of far infrared rays. This is because the far infrared rays emitted by the ceramic insulating layer 412 of the heat generating part 410 are reflected by the reflecting surface 130 provided on the inner diameter surface of the housing 100 in the direction of the discharge hole 120, so that the discharge hole 120 The direct contact with the user's hair results in the use of both convective heat transfer through the air and radiant heat transfer through the far-infrared rays, so that wet hair can be dried in a short time and the hair can be healthy.

Figure 4 is a schematic diagram schematically illustrating a heat generating air integrated hair dryer according to another embodiment of the present invention. Referring to Figure 4, the heating fan integrated hair dryer according to another embodiment of the present invention may be further provided with an auxiliary blowing fan 500 between the body 300 and the intake hole (110).

The auxiliary blowing fan 500 is installed on the rotary shaft 200 and rotated by the rotary shaft 200, and rotates due to the rotary shaft 200 rotated by the motor M (not shown). That is, by rotating the rotary shaft 200, the body 300 and the auxiliary blowing fan 500 can be rotated at the same time to blow more air.

In the above, the present invention has been described based on the preferred embodiments, but the technical idea of the present invention is not limited thereto, and modifications or changes can be made within the scope of the claims. It will be apparent to those skilled in the art, and such modifications and variations will belong to the appended claims.
