In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations.

[First Embodiment]

Hereinafter, a first embodiment according to the present invention will be described in detail with reference to FIGS. 1 to 3.

1 is a perspective view of a hair dryer according to a first embodiment of the present invention, Figure 2 is a cross-sectional view of the hair dryer according to a first embodiment of the present invention, Figure 3 is a longitudinal cross-sectional view along the line AA in FIG. to be.

The first embodiment is an example in which one embodiment of the present invention is applied to a roll brush type hair dryer.

1 and 2, a hair dryer according to an embodiment of the present invention may be divided into a main body 100 and a head part 200. The main body 100 and the head 200 may be detachably connected. Therefore, since the main body 100 may be connected to various types of head parts 200, the user may use a hair dryer having the head part 200 of a desired shape according to his / her choice.

The main body 100 includes a cord 101 for supplying external power, a switch 102 for turning on and off a hair dryer, a display element 103 for indicating on and off of the hair dryer, an intake port 104, and a control unit. 105 and blower fan 106.

The cord 101 (power supply unit) is a component for supplying power to the hair dryer, which is coupled to an external power supply device to supply power to the hair dryer, and the hair dryer is included in the hair using this power supply. The moisture component is dried. Instead of this cord, a built-in secondary battery can be used as the power supply.

The switch 102 is provided on one side of the main body, and the hair dryer user controls the on / off of the hair dryer by using the switch 102.

The display element 103 is a component for informing the user of the operation state of the hair dryer. When the switch 102 is turned on, for example, the display element 103 turns green and the user knows that the hair dryer is in operation. It becomes possible. When the switch 102 is off, the display element 103 turns red, so that the user can know that the hair dryer is not operated.

On the other hand, when the hair dryer is operated through the built-in secondary battery without using an external power source, the display element 103 may be used as a display element for checking the state of charge of the secondary battery. Alternatively, an additional display element may be added to inform the user of the state of charge of the secondary battery.

The intake port 104 is a component for attracting outside air to the inside of the head portion. Referring to FIG. 2, when the built-in blower fan 106 is operated, the outside air is introduced into the main body 100 through the intake port. It is introduced into the head 200. The introduced air is moved toward the head portion 200 by the blowing fan 106.

The control unit 105 controls the degree to which the external power is applied to the heat generating layer (carbon nanotube layer) 208 (also referred to as the first heat generating layer) formed on the inner wall of the head portion 200, which will be described later, so as to generate heat of the heat generating layer. The component that controls the. In the present embodiment, the switch 102 and the control unit 105 have been separately described, but in view of controlling the heat generation degree of the heating layer, which will be described later, the switch 102 may be a concept included in the control unit 105. .

The blowing fan 106 is a component for supplying external air to the head 200, and the air moved by the blowing fan 106 is applied to the first heat generating layer 208 formed on the inner wall of the head 200. Is heated to become hot air. The hot air flows out into the plurality of holes 204 formed in the head 200, and this hot air serves to dry the moisture contained in the hair.

Meanwhile, the head 200 includes a support plate 201, a comb portion 202 including a plurality of comb teeth, and a hole 204. As shown in Figures 1 and 2, the support plate 201 may have a cylindrical shape with a hollow portion. The hollow part means a space that allows the flow of air generated by the above-described blower fan 106 to flow into the inside of the head part 200. Meanwhile, the support plate 201 may include a first outer wall 206, a first heat insulating layer 207, a first heat generating layer 208, and a first heat dissipating layer 209.

Referring to FIGS. 2 and 3, the first outer wall 206 is a component forming an outer shape of the support plate, and may be made of various kinds of plastics, wood materials, polymers, stainless materials, and metal materials. Alternatively, in order to prevent heat conduction, the first heat insulating layer 207 may be formed of the same component.

The first heat insulation layer 207 is a component for preventing heat generated from the first heat generating layer 208 from being transferred to the outside of the support plate 201. That is, when the user uses the hair dryer, heat generated by the first heat generating layer 208 may be conducted to the outside, causing the user to be burned, but the first heat insulating layer 207 may prevent this. To this end, the first heat insulating layer 207 may be made of a general polymer material. In consideration of the temperature of the first heat generating layer 208 to be described later, the first heat insulating layer 207 may be coated with a thickness of about 20 μm-100 μm. If it is less than 20 µm, a sufficient heat insulating effect may not be obtained. If it is larger than 100 µm, it is not preferable in terms of cost or securing the hole 204.

The first heat generating layer 208 is a component for heating the air introduced by the blowing fan 106. The heat generating layer 208 may be a CNT (carbon nanotube). Carbon nanotubes have a hexagonal shape consisting of six carbons connected to each other to form a tubular shape. The diameter of the tube is only a few tens of tens of nanometers, which is called carbon nanotubes. Nanometers are one millionth of a meter, usually one hundredth of a hair's thickness. Its electrical conductivity is similar to that of copper, its thermal conductivity is like the best diamond in nature, and it is 100 times stronger than steel. Carbon fiber can be broken by only 1% deformation, while carbon nanotubes can withstand 15% deformation. Moreover, this carbon nanotube has excellent exothermicity.

Carbon nanotubes include single-walled carbon nanotubes and multi-walled carbon nanotubes. Since multiwall carbon nanotubes are less expensive than single wall carbon nanotubes, considering the commercial viability, multiwall carbon nanotubes are more preferred.

When the carbon nanotubes are used as the first heat generating layer 208, the electrical efficiency is increased, and sufficient hot air generation effect can be obtained even with less energy.

When using multi-walled carbon nanotubes, approximately 10-100 μm thick, may be applied on the first heat insulating layer 207. When it is applied at less than 10 mu m, there is a fear that the incoming air cannot be sufficiently heated. In addition, when applying more than 100 micrometers, when using a built-in secondary battery, it may be difficult to fully maintain the holding time of a hair dryer.

The carbon nanotubes may be applied by a spray method or formed on the first heat insulating layer 207 by a paint coating method.

The first heat dissipation layer 209 serves to better radiate heat generated from the first heat generating layer 208 into the head portion 200. The first heat dissipation layer 209 may be a CNT blended polymer. When the heat generated from the first heat generating layer 208 passes through the first heat dissipating layer 209, the heat is radiated better, and thus the air introduced by the blower fan 106 may be heated better.

The hole 204 is a component for discharging hot air. That is, the air which flowed in by the blowing fan 106 is heated by the 1st heat generating layer 208, and becomes hot air, and this hot air is discharged | emitted to the hole 204.

When the user's hair has a lot of moisture, when the user uses the hair dryer according to the present invention, the hair is attached to the hair by hot air discharged through the hole 204 while completing the hairstyle with a comb portion of a roll brush shape. Will be dried.

According to the first embodiment of the present invention, compared to the coil method, it is possible to provide a thin hair dryer while having high energy efficiency.

[Second Embodiment]

Hereinafter, a second embodiment according to the present invention will be described in detail with reference to FIGS. 4 to 6.

Figure 4 is a perspective view of a hair dryer according to a second embodiment of the present invention, Figure 5 is a cross-sectional view of the hair dryer according to a second embodiment of the present invention, Figure 6 is a longitudinal cross-sectional view along the line BB in Figure 5 to be.

In the second embodiment, the same or similar components as those in the first embodiment are denoted by the same reference numerals, and these components have already been described in detail in the first embodiment, and thus description thereof will be omitted.

4 and 5, unlike the first embodiment, the second embodiment of the present invention includes an ax comb-shaped head portion 200 ′. In addition, unlike the first embodiment, the second embodiment does not include a blowing fan. Instead, the second heating layer 212 is applied to each of the comb teeth 202 ′. That is, moisture is not directly dried by hot air, but is directly dried by heated comb teeth.

The head portion 200 ′ includes a thin support plate 201 ′ and a comb portion 202 ′ formed of a row of combs provided on one side of the support plate. Here, the cut surface of the comb portion, as shown in Figure 5, the second outer wall 210 forming the outer shape of the comb portion, the second heat dissipation layer 211 formed inside the second outer wall, and the second heat dissipation layer ( And a second heat generating layer 212 formed inside of 212.

The second outer wall 210 is a layer forming the outer wall of the comb portion 202 ′, and should be made of a material that conducts heat well from the second heat generating layer 212. That is, a metal with high thermal conductivity or a polymer having high thermal conductivity among polymers is preferably used.

The second heat dissipation layer 211 serves to better radiate heat generated from the second heat generating layer 212 to the inside of the comb portion 202 ′. As the second heat dissipation layer 211, a CNT blended polymer may be used.

The second heat generating layer 212 is a heat generating material and is a component for directly drying the moisture contained in the hair. The second heating layer 212 is a CNT heating layer, and may have a thickness of 5-50 μm. Unlike the first heat generating layer 208, since the second heat generating layer 212 transfers heat by direct conduction, the second heat generating layer 212 may have a sufficient drying effect even with a small amount of heat. When the second heat generating layer is applied at less than 5 μm, sufficient heat may not be transferred to the comb portion 202 ′. Moreover, when apply | coating exceeding 50 micrometers, it is unpreferable in consideration of the thickness of comb teeth.

FIG. 6 is a longitudinal sectional view along the line BB in FIG. 5. As illustrated, the second outer wall 210, the second heat dissipation layer 211, and the second heat generating layer 212 are sequentially stacked on the comb portion 202 ′. In contrast, the second heat generating layer 212 is not coated on the support plate. This is because the support plate 201 'does not play a role in hair drying when the user uses the ax comb-type dryer. That is, the thermal efficiency can be improved by not applying the second heat generating layer 212 inside the support plate 201 ′.
