There is a hair dryer disclosed in -18902. This is, as shown in FIG. 6, a honeycomb-shaped far-infrared radiator 49 at the hot air outlet of the main body 1 of the hair dryer.
Are arranged so that the far-infrared radiator 49 is heated by the warm air sent from the main body 1 so that the far-infrared radiator 49 emits far-infrared rays.

を提供するにある。However, in this case, the far infrared radiator 49
Because it is only heated and its surface area is small, it has little energy for far-infrared rays. Because,
The far-infrared energy amount W is represented by the following equation: W = ε · σ · (T−T 1 ) 4 · S ε: emissivity σ: Stefan-Boltzmann coefficient (constant) T 1 : ambient temperature T: radiator Is the surface area of the radiator.For example, even if the input electric energy required for generating hot air is 1 KW, the far-infrared energy is 10 W
To the extent that it is inefficient for drying hair. Also,
When the emissivity of the far-infrared radiator 49 is measured, as shown in FIG. 7, the emissivity is kept large in the wavelength range of 5 μm to 8 μm, but is large in the wavelength range of 10 μm or more and 2.5 μm to 5 μm. Has a low emissivity. When the absorptivity in the far-infrared wavelength region of the hair wet with water is measured, as shown in FIG. 4, since the absorptivity for the far-infrared ray near 3 μm and near 6 μm and the wavelength of 10 μm or more is high,
In the far-infrared ray radiator 49 having the above emissivity, the wavelength of 6 μm is effectively acting on the drying of the hair wet with water. However, the absorptance for far-infrared rays having a wavelength of about 6 μm is about 3 μm. It is lower than the absorptance for wavelengths around 14μ and is not very effective in this regard. The present invention has been made in view of such a point, and an object of the present invention is to provide a hair dryer which can efficiently and effectively dry hair wet with water and does not hurt the hair. To be.

ほどに低下してしまうために、髪を痛めることもない。Thus, the present invention provides a hair having a far-infrared radiator and a heating member for heating the far-infrared radiator, and drying the hair with far-infrared rays emitted from the far-infrared radiator heated by the heating member. The dryer is characterized in that a far-infrared radiator and a heating member having a maximum emissivity of far-infrared rays near a wavelength of 3 μm are used. [Action] According to the present invention, a hair that is wet with water has a high absorptivity and a dry hair emits a large amount of far-infrared rays having a low absorptivity. [Embodiment] The present invention will be described in detail below with reference to the illustrated embodiment. This hair dryer is rotated by a motor 3 and a cylindrical far-infrared heater 4 having an outer peripheral surface serving as a far-infrared radiation surface. A blower including a driven fan 2 and using the far-infrared heater 4 as a wind tunnel; and a reflector 5 for reflecting far-infrared rays emitted from the far-infrared heater 4 in a blowing direction. The wind sent from the device is heated by heat given from the inner surface of the far infrared heater 4 and is discharged as warm air. In the figure, reference numeral 6 denotes an inlet lattice, and 7 denotes an outlet lattice. As shown in FIG. 2, the far-infrared heater 4 which is designed so that the area of the far-infrared radiation surface can be as large as possible has a spiral shape on the outer peripheral surface of a cylindrical heater base 41 whose tip side is thin. The heater wire 42 is wound along the groove 44, and the far-infrared radiator 43 is further applied and baked on the outer peripheral surface of the heater base 41 around which the heater wire 42 is wound, or by thermal spraying. It is configured as fixed. In the drawing, reference numeral 45 denotes a drawing hole for drawing the heater wire 42 into the inner surface of the heater base 41. As shown in FIG. 3, the far-infrared radiator 43 here has 90% or more over the entire far-infrared wavelength region.
In particular, a material exhibiting a higher emissivity around a wavelength of 3 μm is used. According to the Stefan-Boltzmann law, the amount of far-infrared energy generated from the far-infrared radiator 43 increases in proportion to the fourth power of the temperature of the radiator, as shown in FIG. Wien's displacement law λ m T = 2897 λ m : energy peak wavelength [μ] T: radiator temperature [K] In consideration of the fact that the energy peak wavelength becomes shorter as the temperature of the far-infrared radiator 43 becomes higher, the heater wire 42 By setting the heating of the far-infrared radiator 43 to be 500 to 600 ° C., the energy peak wavelength comes to around 3 μm. Thus, in this far-infrared heater having the far-infrared heater 4 having a large amount of far-infrared radiation of a wavelength near 3 μm, the absorptivity of far-infrared rays of the above-mentioned wavelength in hair wet with water is high. In addition to being able to dry hair quickly, if the hair dries, the absorptivity of far-infrared ray of the above wavelength will be 1/4
It doesn't hurt your hair because it drops so much.

Compared to the case of using a large thing, in addition to being able to be effectively dried because the absorption rate in hair wet with water is high, the absorption rate in dry hair is about 1/4, In particular, the hair does not hurt because of the large difference between the absorbance of wet hair and the absorbance of dry hair.
