The terahertz wave generator 10 generates terahertz waves by heating the hybrid material 11 by the heating unit 12 .
モータ３０は、ブラシモータであってもよいし、ブラシレスモータであってもよい。モータ３０は、ファン４０に接続され、ファン４０を回転させる。
The motor 30 may be a brush motor or a brushless motor. Motor 30 is connected to fan 40 and rotates fan 40 .
ファン４０は、回転することで風を発生させ、吸気口２０から吸気した空気を排気口６０に向けて送風する。ファン４０及びモータ３０は、一体化されていてもよい。ファン４０は、例えば軸流ファンである。なお、送風機構としてブロワを用いてもよく、この場合には軸流ファンよりも低騒音且つ大風量、大吐出圧を期待できる。

（テラヘルツ波の周波数帯域）
次に、テラヘルツ波発生装置１０が発生するテラヘルツ波の周波数帯域について説明する。 (Frequency band of terahertz waves)
Next, the frequency band of the terahertz waves generated by theterahertz wave generator 10 will be described.
次に、テラヘルツ波発生装置１０が発生するテラヘルツ波の周波数帯域について説明する。 (Frequency band of terahertz waves)
Next, the frequency band of the terahertz waves generated by the
図２に示すように、毛髪の構造は、キューティクル（毛表皮）及びＣＭＣ（細胞膜複合体）を含むキューティクル領域Ａと、コルテックス(毛皮質)及びＣＭＣ（細胞膜複合体）を含むコルテックス領域Ｂと、メデュラ（毛髄質）Ｃの３層に分けられる。このように、毛髪の中心部にはメデュラＣがあり、その外側にコルテックス領域Ｂがあり、一番外側にキューティクル領域Ａがある。これらはいずれも大部分（８０～９０％）がケラチンタンパク質からできており、残りがメラニン色素・脂質・水分・微量元素からなっている。ケラチンタンパク質は、普通のタンパク質とは異なり、物理的にも化学的にも強靱である。
As shown in FIG. 2, the structure of hair consists of a cuticle region A containing the cuticle (hair epidermis) and CMC (cell membrane complex), and a cortex region B containing the cortex (cortex) and CMC (cell membrane complex). and the medulla (hair medulla) C. Thus, there is a medulla C in the center of the hair, a cortex region B on the outer side, and a cuticle region A on the outermost side. All of them are mostly (80-90%) composed of keratin protein, and the remainder is composed of melanin pigment, lipids, moisture and trace elements. Keratin proteins are physically and chemically tough, unlike ordinary proteins.
しかし、濡れた毛髪をドライヤで乾かすと、熱による影響で、毛髪のキューティクル及びコルテックスを形づくるケラチンタンパク質が熱変性(タンパク変性)を起こすことがある。濡れた状態の毛髪は、６０℃ほどの熱でも熱変性が進むとされている。タンパク変性すると髪が固くなりゴワツキや切れ毛の原因となる。
However, when wet hair is dried with a dryer, the keratin protein that forms the cuticle and cortex of the hair may undergo thermal denaturation (protein denaturation) due to the heat. Wet hair is said to undergo thermal denaturation even at a temperature of about 60°C. Protein denaturation makes the hair hard and causes stiffness and breakage.
一方、熱変性した毛髪にテラヘルツ波を照射することにより、熱で固まってしまったキューティクル及びコルテックスの組織を断片化して分離し、修復することができる。また、表面だけでなく内部も分離方向になることで毛髪全体がしなやかになる。発明者は、特に３ＴＨｚから２１ＴＨｚのテラヘルツ波を照射した場合に、修復の効果が高いことを確認した。すなわち、ドライヤ１が出力する温風が６０℃を超える場合であっても、同時に上記周波数帯域のテラヘルツ波を髪に照射することで、熱変性によるダメージを軽減させることが可能となる。この効果を得るために、テラヘルツ波発生装置１０は、上記周波数帯域を含む周波数帯域のテラヘルツ波を発生することを特徴とする。
On the other hand, by irradiating heat-denatured hair with terahertz waves, the cuticle and cortex tissue that has hardened due to heat can be fragmented, separated, and repaired. In addition, since not only the surface but also the inside of the hair becomes separated, the entire hair becomes supple. The inventors have confirmed that the restoration effect is particularly high when terahertz waves of 3 THz to 21 THz are irradiated. That is, even if the temperature of the warm air output from the dryer 1 exceeds 60° C., it is possible to reduce damage due to heat denaturation by simultaneously irradiating the hair with terahertz waves in the above frequency band. In order to obtain this effect, the terahertz wave generator 10 is characterized by generating terahertz waves in a frequency band including the above frequency band.
テラヘルツ波発生装置１０は、３ＴＨｚから１５０ＴＨｚまでを含む広い周波数帯域のテラヘルツ波を発生してもよい。４３ＴＨｚから１５０ＴＨｚのテラヘルツ波においては水分の吸収率が高いため、素早く濡れた髪を乾かすことができる。
The terahertz wave generator 10 may generate terahertz waves in a wide frequency band from 3 THz to 150 THz. Since terahertz waves of 43 THz to 150 THz have a high water absorption rate, wet hair can be dried quickly.
図３に、上記のテラヘルツ波発生装置１０の変形例として、テラヘルツ波発生装置１０ａの構成例を示す。図３に示すように、テラヘルツ波発生装置１０ａは、混成材料１１及び加熱部１２に加えて、切替部１３を備える。
FIG. 3 shows a configuration example of a terahertz wave generator 10a as a modification of the terahertz wave generator 10 described above. As shown in FIG. 3 , the terahertz wave generator 10 a includes a switching section 13 in addition to the hybrid material 11 and the heating section 12 .
切替部１３は、ユーザの指示に基づいて、混成材料１１が発生するテラヘルツ波の周波数帯域を選択して切り替える。例えば、切替部１３は、ユーザにより修復モードが選択された場合には、混成材料１１から第１の周波数帯域（例えば、３ＴＨｚから２１ＴＨｚ）のテラヘルツ波を発生させ、ユーザにより速乾モードが選択された場合には、第１の周波数帯域よりも高い第２の周波数帯域（例えば、４３ＴＨｚから１５０ＴＨｚ）のテラヘルツ波を発生させる。
The switching unit 13 selects and switches the frequency band of the terahertz wave generated by the hybrid material 11 based on the user's instruction. For example, when the repair mode is selected by the user, the switching unit 13 generates terahertz waves in the first frequency band (for example, 3 THz to 21 THz) from the hybrid material 11, and the quick-drying mode is selected by the user. In this case, a terahertz wave is generated in a second frequency band (for example, 43 THz to 150 THz) higher than the first frequency band.
切替部１３は、第１の周波数帯域のみ通過させるバンドパスフィルタと、第２の周波数帯域のみ通過させるバンドパスフィルタを用いることで、テラヘルツ波を切り替えることができる。あるいは、混成材料１１として、第１の周波数帯域を発生する第１の混成材料１１－１、及び第２の周波数帯域を発生する第２の混成材料１１－２を用意し、切替部１３は、選択的に混成材料１１－１又は混成材料１１－２を加熱させることで、テラヘルツ波を切り替えることができる。
The switching unit 13 can switch between terahertz waves by using a bandpass filter that passes only the first frequency band and a bandpass filter that passes only the second frequency band. Alternatively, as the hybrid material 11, a first hybrid material 11-1 that generates a first frequency band and a second hybrid material 11-2 that generates a second frequency band are prepared, and the switching unit 13 By selectively heating the hybrid material 11-1 or the hybrid material 11-2, the terahertz wave can be switched.
（混成材料）
次に、混成材料１１の具体例について説明する。混成材料１１は、ゲルマニウム又はケイ素（シリコン）の単体であってもよい。実験によれば、テラヘルツ波の放射量はゲルマニウムのほうが多かった。また、混成材料１１は、ゲルマニウム又はケイ素に加え、カーボン、酸化カルシウム、酸化ケイ素、酸化アルミニウム、チタン、モリブデン、タングステン、タンタル、ニオブ、プラチナ、及びニッケルクロムのうち少なくとも１つを含む材料とすることで、水の吸収波長帯域でも高放射率を維持することができる。混成材料１１は、さらにセメントを混ぜてセラミック材としてもよい。 (composite material)
Next, specific examples of thehybrid material 11 will be described. The composite material 11 may be germanium or silicon (silicon) alone. Experiments have shown that germanium emits more terahertz waves than germanium. In addition to germanium or silicon, the hybrid material 11 is a material containing at least one of carbon, calcium oxide, silicon oxide, aluminum oxide, titanium, molybdenum, tungsten, tantalum, niobium, platinum, and nickel chromium. , it is possible to maintain high emissivity even in the absorption wavelength band of water. The hybrid material 11 may be further mixed with cement to form a ceramic material.

混成材料１１は、加熱部１２により高温に加熱される。混成材料１１を高温に加熱するほどテラヘルツ波のエネルギーを大きくすることができる。しかし、テラヘルツ波発生装置１０をヘアドライヤとして使用する場合には、排気口６０から出力される温風の温度を１２０℃以下とすることが望ましい。なお、ＪＩＳ（日本工業規格）の規定では、室温が３０℃で吹き出し口から３ｃｍのところの温度が１４０℃以下と定められている。そのため、混成材料１１の加熱時の温度は、混成材料１１の大きさ、混成材料１１から排気口６０までの距離、風速などに応じて制御する必要がある。これらを考慮すると、ドライヤ１が一般的なサイズの場合、加熱部１２は、混成材料１１を３００℃から１５００℃の温度で加熱することが望ましい。
The hybrid material 11 is heated to a high temperature by the heating section 12 . The energy of the terahertz wave can be increased as the hybrid material 11 is heated to a higher temperature. However, when using the terahertz wave generator 10 as a hair dryer, it is desirable that the temperature of the hot air output from the exhaust port 60 is 120° C. or less. JIS (Japanese Industrial Standards) stipulates that the room temperature is 30° C. and the temperature at a point 3 cm from the outlet is 140° C. or less. Therefore, it is necessary to control the temperature of the composite material 11 during heating according to the size of the composite material 11, the distance from the composite material 11 to the exhaust port 60, the wind speed, and the like. Considering these, when the dryer 1 is of a general size, the heating unit 12 preferably heats the composite material 11 at a temperature of 300°C to 1500°C.
（反射板）
次に、反射板５０の素材及び配置について説明する。反射板５０の素材は、テラヘルツ波を効率よく反射する素材であればよく、例えば金である。テラヘルツ波のエネルギーは距離の２乗に反比例するため、反射板５０はテラヘルツ波発生装置１０の近くに配置される。例えば、反射板５０は、テラヘルツ波発生装置１０から、１ｍｍから１ｃｍの間隔をあけて配置されることが望ましい。反射板５０は複数枚あってもよい。 (a reflector)
Next, the material and arrangement of thereflector 50 will be described. The material of the reflector 50 may be any material that efficiently reflects the terahertz wave, such as gold. Since the energy of the terahertz wave is inversely proportional to the square of the distance, the reflector 50 is arranged near the terahertz wave generator 10 . For example, the reflector 50 is desirably arranged with an interval of 1 mm to 1 cm from the terahertz wave generator 10 . A plurality of reflectors 50 may be provided.

Further, the terahertz wave generator 10a further includes a switching unit 13 that selects and switches the frequency band of the terahertz wave generated by the composite material 11 based on the user's instruction, thereby selecting the frequency band according to the application. becomes possible. For example, if your hair is damaged, you can select the repair mode (first frequency band), and if you are in a hurry, you can select the quick-drying mode (second frequency band). It is possible to improve convenience and customer satisfaction.
テラヘルツ波発生装置１０を搭載したドライヤ１は、人間用のみならず、動物用（ペット用）としても使用することができる。また、ドライヤ１は、その温熱効果により、人間及び動物の血流改善用途で使用することもできる。ドライヤ１の各構成は、運用目的対象によってフレキシブルに最適なサイズ、レイアウトを構築することができる。
