Abstract

A fan, as one example of a blowing device, is provided with: a microcomputer, as one example of a control unit, for executing a blowing control that generates a weak air current (21) for blowing a small volume of air, and a strong air current (22) for blowing a large volume of air that is greater than the small volume of air; and a scent-generating unit that outputs a scent. The microcomputer is capable of setting, in advance, an air volume variation range (25) that is the difference between a strong starting air volume (23), which is the volume of air when transitioning from the weak air current (21) to the strong air current (22), and a strong maximum air volume (24), which is the maximum volume of air of the strong air current (22). During the strong maximum air volume (24), the microcomputer mixes the scent outputted from the scent-generating unit with the air of the strong maximum air volume (24).

Description

送風装置および送風制御プログラムBlower and blower control program
　本発明は、送風量がゆらぐように空気を送風する送風装置および送風制御プログラムにおいて、香りを提供する装置に関する。 This invention relates to the apparatus which provides fragrance in the air blower which blows air so that air flow may fluctuate, and an air supply control program.
　室内空間の快適性を向上させるため、風、光、音、温熱環境について様々な検討が実施されている。例えば風に関して、人に好まれる風は１／ｆゆらぎに近い風であることが様々な文献において報告されており、広く知られている。これは、風量の変化を１／ｆゆらぎにすることで、自然の風のゆらぎに近づくため、一定風量の風よりも心地よさを与えられると考えられている。そこで、従来送風量に強弱を与えることで１／ｆゆらぎの送風を行う空気調和機がある（例えば、特許文献１参照）。 In order to improve the comfort of indoor spaces, various studies have been conducted on wind, light, sound, and thermal environment. For example, with regard to wind, it is widely known that various types of literature report that the wind preferred by humans is close to 1 / f fluctuation. This is thought to be more comfortable than a constant airflow because the change in airflow is 1 / f fluctuation to approach the natural wind fluctuation. Therefore, there is an air conditioner that blows 1 / f fluctuations by giving strength to the amount of blown air (for example, see Patent Document 1).
　以下、その空気調和機の送風時の送風制御プログラムについて図１２を参照しながら説明する。 Hereinafter, a ventilation control program at the time of ventilation of the air conditioner will be described with reference to FIG.
　図１２に示すように、送風制御プログラム１０１は、１／ｆゆらぎでゆらぐ送風量に対応するファンの回転数の基本パターンに基づき、ファン回転数を変化させる第１送風パターン１０２と第２送風パターン１０３とから構成される。第１送風パターン１０２は、予め設定したファンの回転数の第１上限値１０４と第１下限値１０５との間で基本パターンに基づき、ファンの回転数を変化させるものである。一方で、第２送風パターン１０３は、第１送風パターン１０２よりもファンの回転数の振幅を小さくした第２上限値１０６と第２下限値１０７との間で基本パターンに基づき、ファンの回転数を変化させるものである。そして、第２送風パターン１０３が第１送風パターン１０２と第１送風パターン１０２との間に入るように設定されているものである。これにより、送風量の変化が小さい第２送風パターン１０３と、送風量の変化が大きい第１送風パターン１０２とを交互に組み合わせることで、第１送風パターン１０２が連続で続く場合よりも、送風量の変化幅を小さくすることができ、理想的なファン送風量と実際のファンの送風量のズレを生じ難くするものである。 As shown in FIG. 12, the air blowing control program 101 has a first air blowing pattern 102 and a second air blowing pattern that change the fan rotation speed based on the basic pattern of the fan rotation speed corresponding to the air flow amount fluctuating with 1 / f fluctuation. 103. The first air blowing pattern 102 changes the fan rotation speed based on a basic pattern between a first upper limit value 104 and a first lower limit value 105 of the preset fan rotation speed. On the other hand, the second air blowing pattern 103 is based on the basic pattern between the second upper limit value 106 and the second lower limit value 107 in which the amplitude of the fan rotation speed is smaller than that of the first air blowing pattern 102, and the fan rotation speed. Is something that changes. And the 2nd ventilation pattern 103 is set so that it may enter between the 1st ventilation pattern 102 and the 1st ventilation pattern 102. As a result, by alternately combining the second air blowing pattern 103 with a small change in the air flow rate and the first air blowing pattern 102 with a large air flow rate change, the air flow rate is greater than when the first air blowing pattern 102 continues continuously. Therefore, it is difficult to cause a deviation between the ideal fan air flow rate and the actual fan air flow rate.

　上記従来例では、送風量の変化が小さい第２送風パターン１０３と送風量の変化が大きい第１送風パターン１０２とを交互に組み合わせることで、送風量の変化幅を小さくするゆらぎ制御について述べられている。しかし、従来例の課題として、第１送風パターン１０２から第２送風パターン１０３へ移行する際、送風量の変化幅が小さくなることで、ユーザーが風速変化のない人工的な風と感じてしまう課題があった。 In the above-mentioned conventional example, the fluctuation control for reducing the change width of the air flow rate by alternately combining the second air flow pattern 103 with a small change in air flow rate and the first air flow pattern 102 with a large change in air flow rate is described. Yes. However, as a problem of the conventional example, when shifting from the first air blowing pattern 102 to the second air blowing pattern 103, a problem that the user feels an artificial wind without a change in the wind speed due to a small change width of the air blowing amount. was there.
　すなわち、上記従来例のゆらぎ制御プログラムにおいて、ユーザーが一定風速の人工的な風を浴びていると感じ、風の自然さを感じられないという課題があった。 That is, in the above-described conventional fluctuation control program, there is a problem that the user feels that the user is taking an artificial wind at a constant wind speed and cannot feel the naturalness of the wind.
　そこで本発明は、上記従来例を解決するものであり、より自然なゆらぎを感じる風と自然な香りをユーザーに提供することを目的とする。 Therefore, the present invention solves the above-described conventional example, and an object thereof is to provide a user with a wind and a natural scent that feels more natural fluctuations.
　本発明の一態様に係る送風装置は、小風量を送風する弱気流と、小風量よりも大きな大風量を送風する強気流とを発生させる送風制御を実行する制御部と、香りを導出する香り発生部と、を備える。制御部は、弱気流から強気流へ移行する際の風量である強開始風量と、強気流の最大風量である強上限風量との差である風量変化幅を予め設定可能である。そして、強気流の最大風量である強上限風量の間、香り発生部から導出する香りを強上限風量の風に同伴する。 A blower according to an aspect of the present invention includes a control unit that performs a blow control that generates a weak air flow that blows a small air amount and a strong air flow that blows a large air amount larger than the small air amount, and a scent that derives a scent A generator. The control unit can preset an air volume change width that is a difference between a strong start air volume that is an air volume when transitioning from a weak air stream to a strong air stream and a strong upper air volume that is a maximum air volume of the strong air stream. And the fragrance derived | led-out from a fragrance generation | occurrence | production part is accompanied with the wind of a strong upper limit air volume during the strong upper air volume which is the maximum air volume of a strong air current.
　これにより、強上限風量の送風の間、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザーに提供することができる。また、強上限風量の風に香りを同伴させるため、高濃度の香りが風に同伴され、ユーザーが香りを明確に感じることができる。更に、人間の鼻はずっと同じ香りを嗅ぎ続けると嗅覚疲労を起こすが、強上限風量の風の間のみ香りが同伴されるため、嗅覚疲労の増加を抑制できる。 This makes it possible to bring the scent into the wind during the blowing of the strong upper air volume, and to provide the user with a wind that feels more natural and a scent that feels nature. In addition, since the scent is accompanied by the wind having a strong upper limit air volume, a high concentration of scent is accompanied by the wind, and the user can clearly feel the scent. Furthermore, when the human nose keeps sniffing the same scent for a long time, it causes olfactory fatigue. However, since the scent is accompanied only by the wind with a strong upper air volume, an increase in olfactory fatigue can be suppressed.

The control unit can preset an air volume change width that is a difference between a strong start air volume that is an air volume when transitioning from a weak air stream to a strong air stream and a strong upper air volume that is a maximum air volume of the strong air stream. And a control part accompanies the fragrance derived | led-out from a scent generation | occurrence | production part to the wind of a strong upper limit air volume during the strong upper limit air volume which is the maximum air volume of a strong air current. Thereby, it is possible to prevent the user from feeling that the wind is an artificial wind without a change in the wind speed, and to make the user feel a large change in the wind speed seen in the natural wind. Then, the scent can be caused to accompany the wind during the blowing of the strong upper limit air volume, and a wind that feels more natural fluctuation and a scent that feels nature can be provided to the user. In addition, since the scent is accompanied by the wind having a strong upper limit air volume, a high concentration of scent is accompanied by the wind, and the user can clearly feel the scent. Furthermore, when the human nose continues to smell the same scent, it causes olfactory fatigue. However, since the scent is accompanied only by the wind of the strong upper air volume, an increase in olfactory fatigue can be suppressed.
　また、本発明の一態様に係る送風装置は、小風量を送風する弱気流と、小風量よりも大きな大風量を送風する強気流とを発生させる送風制御を実行する制御部と、香りを導出する香り発生部と、を備える。制御部は、弱気流から強気流へ移行する際の風量である強開始風量と、強気流の最大風量である強上限風量との差である風量変化幅を予め設定可能である。そして、制御部は、小風量を送風する弱気流の間、香り発生部から導出する香りを弱気流に同伴する。これにより、弱気流の間、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザーに提供することができる。また、人間の鼻はずっと同じ香りを嗅ぎ続けると嗅覚疲労を起こすが、弱気流の間のみ、香りが同伴されるため、嗅覚疲労の増加を抑制できるという効果を奏する。 In addition, a blower device according to an aspect of the present invention derives a scent from a control unit that performs a blow control that generates a weak air flow that blows a small air volume and a strong air stream that blows a large air volume larger than the small air volume. A scent generating part. The control unit can preset an air volume change width that is a difference between a strong start air volume that is an air volume when transitioning from a weak air stream to a strong air stream and a strong upper air volume that is a maximum air volume of the strong air stream. And a control part accompanies the fragrance derived | led-out from a scent generation | occurrence | production part in a weak airflow during the weak airflow which ventilates a small air volume. Thereby, a fragrance can be accompanied by a wind during weak air current, and a wind that feels more natural fluctuations and a scent that feels nature can be provided to the user. In addition, when the human nose continues to smell the same scent, it causes olfactory fatigue. However, since the scent is accompanied only during a weak air flow, an increase in olfactory fatigue can be suppressed.

A scent generating part. The control unit can preset an air volume change width that is a difference between a strong start air volume that is an air volume when transitioning from a weak air stream to a strong air stream and a strong upper air volume that is a maximum air volume of the strong air stream. And a control part accompanies the fragrance derived | led-out from a fragrance generation | occurrence | production part with weak air current and strong air current. As a result, since the air volume is large during the blowing of the strong upper air volume, a large amount of scent reaches the user and can provide a high concentration of scent. It can reach and provide a low-concentration fragrance. Moreover, without using a complicated mechanism, a scent having a concentration corresponding to the volume of the wind can be accompanied by the wind, and a wind that feels more natural fluctuations and a scent that feels nature can be provided to the user.

　（特徴３）図６に示すように、自然の風の風速は、大波形１８と風速が１．０ｍ／ｓ以下の風速の波形である小波形１９とが交互に発生する構成となっている。 (Characteristic 3) As shown in FIG. 6, the wind speed of the natural wind is such that a large waveform 18 and a small waveform 19 that is a wind speed waveform of 1.0 m / s or less are alternately generated. .
　（特徴４）図６に示すように、小波形１９から大波形１８が発生する際の風速の変化量である風速変化幅２０は、０．４ｍ／ｓから１．２ｍ／ｓの範囲である。 (Characteristic 4) As shown in FIG. 6, the wind speed change width 20 which is the amount of change in the wind speed when the large waveform 18 is generated from the small waveform 19 is in the range of 0.4 m / s to 1.2 m / s. .
　前述した自然の風の特徴において、特に（特徴４）の風速変化幅２０が前述の範囲であることで、ユーザー５が明確に風速の変化を知覚し、風のゆらぎから自然の風を想起し、心地よいと感じるのである。 Among the characteristics of the natural wind described above, in particular, because the wind speed change width 20 of (Feature 4) is in the above-described range, the user 5 clearly perceives the change in the wind speed and recalls the natural wind from the fluctuation of the wind. I feel comfortable.
　本実施の形態において、ゆらぎ制御プログラム１５は、前述した自然の風の（特徴１）から（特徴４）に基づいた風速の変化をユーザー５に与えられるように、モーター１２の回転数を変化させ、プロペラファン６から送風する風量を制御する。以下に本実施の形態に係る送風装置のゆらぎ制御について述べる。 In the present embodiment, the fluctuation control program 15 changes the rotation speed of the motor 12 so that the user 5 can be given the change in wind speed based on the above-mentioned natural wind (feature 1) to (feature 4). The amount of air blown from the propeller fan 6 is controlled. Hereinafter, fluctuation control of the blower according to the present embodiment will be described.
　図７は、本実施の形態に係る扇風機３の風量変化を示すグラフである。図７に示すように、扇風機３は、風量が４００ｍ３／ｈで送風を行う弱気流２１と、風量が弱気流２１より大きく１０００ｍ３／ｈで送風を行う強気流２２とを交互に行う。このとき、扇風機３とユーザー５との距離が約２ｍの場合にユーザー５の位置で測定される風速が、弱気流２１では０．４ｍ／ｓであり、強気流２２では１．６ｍ／ｓである。また、弱気流２１と強気流２２の風量は、風量変化幅２５に基づいて設定されている。風量変化幅２５は、弱気流２１から強気流２２へ移行する際の風量である強開始風量２３と、強気流２２の最大風量である強上限風量２４との差である。風量変化幅２５は、前述した自然の風における風速変化幅２０を満たす範囲で設定されている。 FIG. 7 is a graph showing changes in the air volume of the electric fan 3 according to the present embodiment. As shown in FIG. 7, the electric fan 3 alternately performs a weak airflow 21 that blows air at an air volume of 400 m 3 / h and a strong airflow 22 that blows air at a flow rate larger than the weak airflow 21 by 1000 m 3 / h. At this time, when the distance between the fan 3 and the user 5 is about 2 m, the wind speed measured at the position of the user 5 is 0.4 m / s for the weak air flow 21 and 1.6 m / s for the strong air flow 22. is there. Further, the air volumes of the weak air stream 21 and the strong air stream 22 are set based on the air volume change width 25. The air volume change width 25 is a difference between the strong start air volume 23 that is an air volume when the weak air flow 21 is shifted to the strong air stream 22 and the strong upper limit air volume 24 that is the maximum air volume of the strong air stream 22. The air volume change width 25 is set in a range that satisfies the wind speed change width 20 in the natural wind described above.
　本実施の形態では、１．２ｍ／ｓの風速変化幅２０を満たすように、弱気流２１の風量と強気流２２の風量とをそれぞれ設定した。したがって、自然の風に見られる風速変化幅２０を満たす風量変化幅２５に基づいて、弱気流２１と強気流２２とを交互に発生させることができる。このことで、風速変化のない人工的な風であるとユーザー５が感じることを防止し、自然の風に見られる大きな風速の変化を確実にユーザー５に感じさせることができる。これにより、自然なゆらぎを感じさせる風をユーザー５に提供することができる。 In the present embodiment, the air volume of the weak air stream 21 and the air volume of the strong air stream 22 are set so as to satisfy the wind speed change width 20 of 1.2 m / s. Therefore, the weak air flow 21 and the strong air flow 22 can be generated alternately based on the air volume change width 25 that satisfies the wind speed change width 20 found in natural wind. Thus, it is possible to prevent the user 5 from feeling that the wind is an artificial wind without a change in the wind speed, and to make the user 5 feel a large change in the wind speed seen in the natural wind. Thereby, the wind which makes a natural fluctuation feel can be provided to the user 5.
　また、図７に示すように、強開始風量２３から強上限風量２４へ到達するまでに要する時間である増加時間２６を予め設定した。すなわち、増加時間２６が、ゆらぎ制御プログラム１５に書き込まれている。加えて、強上限風量２４から、強気流２２から弱気流２１へ移行する際の風量である弱気流移行風量２７まで到達するために必要な時間である減少時間２８も設定した。すなわち、減少時間２８が、ゆらぎ制御プログラム１５に書き込まれている。これにより、風量増加あるいは風量減少に要する時間が過度に長くなることを防止できる。そのため、ユーザー５が風速の変化に慣れてしまい、風速変化のない人工的な風に感じることを防止することができる。また、風量増加あるいは風量減少に要する時間が過度に短くなることを防止できる。そのため、風による刺激の強さの急激な変化により、ユーザー５を驚かす、または、不快に感じさせることを防止できる。このとき、増加時間２６および減少時間２８は５秒に設定した。増加時間２６及び減少時間２８について、ユーザー５が扇風機３の操作部（図示せず）より適宜設定できる構成であってもよい。 Further, as shown in FIG. 7, an increase time 26, which is a time required to reach the strong upper air flow 24 from the strong start air flow 23, is preset. That is, the increase time 26 is written in the fluctuation control program 15. In addition, a decrease time 28, which is the time required to reach the weak airflow transition air volume 27, which is the air volume when moving from the strong airflow 22 to the weak airflow 21, from the strong upper limit airflow 24 is also set. That is, the decrease time 28 is written in the fluctuation control program 15. As a result, it is possible to prevent the time required to increase or decrease the air volume from becoming excessively long. Therefore, it is possible to prevent the user 5 from getting used to the change in the wind speed and feeling an artificial wind without the change in the wind speed. In addition, it is possible to prevent the time required for increasing or decreasing the air volume from becoming excessively short. Therefore, it is possible to prevent the user 5 from being surprised or uncomfortable due to a sudden change in the intensity of stimulation caused by the wind. At this time, the increase time 26 and the decrease time 28 were set to 5 seconds. The configuration in which the user 5 can appropriately set the increase time 26 and the decrease time 28 from an operation unit (not shown) of the electric fan 3 may be adopted.
　なお、信号線１４は、有線のコードである。しかし、これに限らず、制御基板１３が無線通信によりモーター１２に信号を送信しても良い。 The signal line 14 is a wired cord. However, the present invention is not limited to this, and the control board 13 may transmit a signal to the motor 12 by wireless communication.
　なお、弱気流２１の風量は４００ｍ３／ｈに限定されるものではなく、強気流２２の風量も１０００ｍ３／ｈに限定されるものではない。 Note that the air volume of the weak air flow 21 is not limited to 400 m 3 / h, and the air volume of the strong air flow 22 is not limited to 1000 m 3 / h.
　なお、本実施の形態では風速変化幅２０を１．２ｍ／ｓに設定したが、前述の自然の風の（特徴４）に基づき、０．４ｍ／ｓ以上、１．２ｍ／ｓ以下の値であれば好ましく、より好ましくは０．６ｍ／ｓ以上、１．２ｍ／ｓ以下である。 In this embodiment, the wind speed variation width 20 is set to 1.2 m / s. However, based on the above-described natural wind (feature 4), the value is 0.4 m / s or more and 1.2 m / s or less. If it is, it is preferable, More preferably, it is 0.6 m / s or more and 1.2 m / s or less.
　なお、増加時間２６および減少時間２８は５秒に限らずそれぞれ２秒以上、１５秒以下であることが好ましく、より好ましくは５秒以上、１０秒以下である。 The increase time 26 and the decrease time 28 are not limited to 5 seconds, but are preferably 2 seconds or more and 15 seconds or less, more preferably 5 seconds or more and 10 seconds or less.
　次に、前述した自然のゆらぎを感じる風を提供する際に、自然の香りも併せて提供する場合について説明する。 Next, the case where a natural scent is also provided when the wind that feels the natural fluctuation described above is provided will be described.
　図８は、実施の形態１に係る送風装置に香りを提供する香り発生部を設けた場合の図２におけるＡ－Ａ断面において、特にガード１０の裏に位置する動力部１１を示す断面図である。 FIG. 8 is a cross-sectional view showing the power unit 11 located on the back of the guard 10 in the AA cross section in FIG. 2 when the scent generating unit for providing the scent is provided in the air blower according to the first embodiment. is there.
　図８において、図３に示した符号と同様の符号を付したものは、前述と同様の動作を行なう。図８では、動力部１１に、香り発生部である、香料を設置しておく香料設置部５０と、香料設置部５０から外部へ香りを導出するためのシャッター５１とが設けられている。また、動力部１１内の制御基板１３からは、制御基板１３とシャッター５１との間で信号の受け渡しを行う信号線１４が設けられている。これにより、制御基板１３は、モーター１２の回転数及びシャッター５１の開閉を制御する。なお、香料設置部５０は、自然な香りである、花の香りや森の香り（フィトンチッド）等の香料を格納できるもので、動力部１１を覆うカバー外部から香料を簡単に挿入／交換できるようになっている。 In FIG. 8, those denoted by the same reference numerals as those shown in FIG. 3 perform the same operations as described above. In FIG. 8, the power unit 11 is provided with a fragrance installation unit 50 for installing a fragrance, which is a fragrance generation unit, and a shutter 51 for deriving the scent from the fragrance installation unit 50 to the outside. In addition, a signal line 14 is provided from the control board 13 in the power unit 11 to exchange signals between the control board 13 and the shutter 51. Thereby, the control board 13 controls the rotation speed of the motor 12 and the opening / closing of the shutter 51. In addition, the fragrance | flavor installation part 50 can store fragrance | flavors, such as the fragrance of a flower which is a natural fragrance, and the fragrance of a forest (phytoncide), so that fragrance | flavor can be easily inserted / exchanged from the outside of the cover which covers the power part 11. It has become.
　これらの構成により、扇風機３は制御基板１３から送信される信号に基づいて、モーター１２の回転数を変化させることで、ユーザー５に送風する風量を変化させ、その風量変化に併せてシャッター５１を開閉させることで、香りの発生を変化させる。 With these configurations, the electric fan 3 changes the amount of air blown to the user 5 by changing the number of revolutions of the motor 12 based on the signal transmitted from the control board 13, and the shutter 51 is moved along with the change in the air amount. Opening and closing changes the generation of fragrance.
　図９は、制御基板１３内部におけるモーター１２及び香りを導出させるためのシャッター５１の制御系の構成を示す機能ブロック図である。 FIG. 9 is a functional block diagram showing the configuration of the control system of the shutter 51 for deriving the motor 12 and the scent inside the control board 13.
　制御基板１３は、制御部としてのマイコン１６と、信号出力部１７とを含む。マイコン１６は、予め設定された時系列でモーター１２の回転数を変化させる送風制御プログラムの一例としてのゆらぎ制御プログラム１５を記憶する。マイコン１６は、さらにマイコン１６に記憶されたゆらぎ制御プログラム１５を実行することにより、モーター１２を制御するための信号を生成する。信号出力部１７は、モーター１２にその信号を送信する。また、マイコン１６は、モーター１２の回転数を変化に併せてシャッター５１を開閉するためのプログラムの一例であるゆらぎ制御プログラム１５も記憶する。マイコン１６は、さらにマイコン１６に記憶されたシャッター５１を開閉するためのプログラムの一例であるゆらぎ制御プログラム１５を実行することにより、シャッター５１を制御するための信号を生成する。信号出力部１７は、この信号をシャッター５１にも出力する。つまり、制御基板１３は、信号線１４を介してゆらぎ制御プログラム１５に基づいた信号をモーター１２及びシャッター５１に送る。これにより、モーター１２の回転数を時系列で変化させ、ユーザー５に送風する風量を変化させ、その風量変化に併せてシャッター５１を開閉させることで、香りの発生を変化させることができる。なお、シャッター５１の開閉は、両矢印（図８では上下方向）の方向にシャッター５１が移動することにより行われる。具体的には、シャッター５１が下方向に移動すると“開”状態、シャッター５１が上方向に移動すると“閉”状態となる。このシャッター５１は、図示しない開閉用のモーターによりシャッター５１が“開”状態から“閉”状態、“閉”状態から“開”状態へ移動される。また、シャッター５１はシャッター機構として説明しているが、ダンパー機構として開閉状態を制御するようにしてもよい。 The control board 13 includes a microcomputer 16 as a control unit and a signal output unit 17. The microcomputer 16 stores a fluctuation control program 15 as an example of a ventilation control program that changes the rotation speed of the motor 12 in a preset time series. The microcomputer 16 further generates a signal for controlling the motor 12 by executing the fluctuation control program 15 stored in the microcomputer 16. The signal output unit 17 transmits the signal to the motor 12. The microcomputer 16 also stores a fluctuation control program 15 that is an example of a program for opening and closing the shutter 51 in accordance with the change in the rotation speed of the motor 12. The microcomputer 16 further generates a signal for controlling the shutter 51 by executing a fluctuation control program 15 which is an example of a program for opening and closing the shutter 51 stored in the microcomputer 16. The signal output unit 17 also outputs this signal to the shutter 51. That is, the control board 13 sends a signal based on the fluctuation control program 15 to the motor 12 and the shutter 51 via the signal line 14. Thereby, the number of rotations of the motor 12 is changed in time series, the amount of air blown to the user 5 is changed, and the shutter 51 is opened and closed in accordance with the change in the air amount, thereby changing the generation of scent. The shutter 51 is opened and closed by moving the shutter 51 in the direction of a double arrow (vertical direction in FIG. 8). Specifically, when the shutter 51 moves downward, the state is “open”, and when the shutter 51 moves upward, the state is “closed”. The shutter 51 is moved from an “open” state to a “closed” state and from a “closed” state to an “open” state by an opening / closing motor (not shown). Although the shutter 51 is described as a shutter mechanism, the open / close state may be controlled as a damper mechanism.
　このような構成において、前述した図７に示すような風量の制御を行なった際、香りを発生させる場合について説明する。 In such a configuration, a case where a scent is generated when the air volume control as shown in FIG. 7 is performed will be described.
　制御基板１３は、図７における強上限風量２４の風量で送風している場合には、シャッター５１を“開”状態となるように信号出力部１７からシャッター５１へ信号を出力する。また、制御基板１３は、強上限風量２４の風量で送風しない場合には、シャッター５１を“閉”状態となるように信号出力部１７からシャッター５１へ信号を出力する。シャッター５１が“開”状態の場合、香料設置部５０に格納されている香料から、香りが破線矢印の方向に導出される。そして、動力部１１の前方（破線矢印の方向）にある回転体８及び翼９（図３参照）によって、送風する風に香りを同伴させることができる。つまり、送風方向に香料を拡散することができる。なお、香料には、人が自然な香りと感じる森の香り（フィトンチッド）が使用されているものとする。 The control board 13 outputs a signal from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state when the air is blown at the air flow rate of the strong upper air flow 24 in FIG. Further, the control board 13 outputs a signal from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “closed” state when the air is not blown with the air flow of the strong upper limit air flow 24. When the shutter 51 is in the “open” state, the fragrance is derived from the fragrance stored in the fragrance setting unit 50 in the direction of the broken line arrow. And the scent can be accompanied by the wind which blows with the rotary body 8 and the wing | blade 9 (refer FIG. 3) in front of the motive power part 11 (direction of a broken-line arrow). That is, the fragrance can be diffused in the blowing direction. In addition, the fragrance of the forest (phytoncide) which a person feels a natural fragrance shall be used for a fragrance | flavor.
　これにより、強上限風量２４の送風の間、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザー５に提供することができる。また、強上限風量２４の風に香りを同伴させるため、高濃度の香りが風に同伴され、ユーザー５が香りを明確に感じることができる。更に、人間の鼻はずっと同じ香りを嗅ぎ続けると嗅覚疲労を起こすが、強上限風量２４の風の間のみ、香りが同伴されるため、嗅覚疲労の増加を抑制できる。 Thus, the scent can be accompanied by the wind during the blowing of the strong upper air volume 24, and the user 5 can be provided with a wind that feels more natural fluctuation and a scent that feels nature. Moreover, since a scent is accompanied by the wind of the strong upper limit air volume 24, a high concentration scent is accompanied by the wind, and the user 5 can clearly feel the scent. Furthermore, when the human nose continues to smell the same scent, it causes olfactory fatigue. However, since the scent is accompanied only by the wind with the strong upper air volume 24, the increase in olfactory fatigue can be suppressed.
　また、制御基板１３は、図７における弱気流２１の風量で送風している場合には、シャッター５１を“開”状態となるように信号出力部１７からシャッター５１へ信号を出力してもよい。そして、制御基板１３は、弱気流２１で送風しない場合には、シャッター５１を“閉”状態となるように信号出力部１７からシャッター５１へ信号を出力するようにしてもよい。これにより、弱気流２１の間、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザー５に提供することができる。また、人間の鼻はずっと同じ香りを嗅ぎ続けると嗅覚疲労を起こすが、弱気流２１の間のみ、香りが同伴されるため、嗅覚疲労の増加を抑制できる。 7 may output a signal from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state. . The control board 13 may output a signal from the signal output unit 17 to the shutter 51 so that the shutter 51 is in a “closed” state when the air is not blown by the weak air flow 21. Thereby, a fragrance can be caused to accompany the wind during the weak airflow 21, and a wind that feels more natural fluctuations and a scent that feels nature can be provided to the user 5. Further, if the human nose continues to smell the same scent, it causes olfactory fatigue. However, since the scent is accompanied only during the weak air flow 21, an increase in olfactory fatigue can be suppressed.
　また、動力部１１内に、香り発生部である、香料設置部５０及びシャッター５１を複数備え、香料設置部５０には夫々異なる香料が格納される構成としてもよい。この構成によれば、制御基板１３が、前述と同様のシャッター開閉動作を行い、図７における強上限風量２４の風量と、弱気流２１の風量とで、異なる香りを風に同伴させることができる。これにより、人間の鼻はずっと同じ香りを嗅ぎ続けると嗅覚疲労を起こすが、強上限風量２４と弱気流２１の風量とで、異なる香りが同伴されるため、嗅覚疲労の増加を抑制できる。 Further, the power unit 11 may include a plurality of fragrance setting units 50 and shutters 51 that are scent generating units, and the fragrance setting unit 50 may store different fragrances. According to this configuration, the control board 13 performs the same shutter opening / closing operation as described above, and can bring different scents into the wind depending on the air volume of the strong upper limit air volume 24 and the air volume of the weak airflow 21 in FIG. . As a result, if the human nose continues to smell the same scent, olfactory fatigue occurs. However, since different scents are accompanied by the high upper air volume 24 and the weak air flow 21, the increase in olfactory fatigue can be suppressed.
　また、動力部１１内に、香り発生部である、香料設置部５０及びシャッター５１を複数備え、香料設置部５０には夫々異なる香料が格納される構成を用い、マイコン１６に時計機能を備えることにより、季節や時間帯に合わせて風に同伴される香りを変化させてもよい。 The power unit 11 includes a plurality of fragrance setting units 50 and shutters 51, which are scent generating units, and the fragrance setting unit 50 has a configuration in which different fragrances are stored, and the microcomputer 16 has a clock function. Thus, the scent accompanying the wind may be changed according to the season or time zone.
　更に、扇風機３の外気に接する部分に温度センサー（図示しない）を備え、その温度センサーからの温度情報に基づき、温度に合わせて風に同伴される香りを変化させてもよい。この場合、例えば外気温度が３０℃以上であれば、人間が涼しさを感じるミントの香料でミントの香りを風に同伴させる。また、例えば外気温度が１０℃以下であれば、人間が暖かさを感じる甘い香りの香料で甘い香りを風に同伴させる。また、例えば外気温度が１０～３０℃であれば、人間が自然な香りと感じる森の香り（フィトンチッド）を風に同伴させる。これにより、ユーザー５に優しい風を提供することができる。 Furthermore, a temperature sensor (not shown) may be provided in a portion of the electric fan 3 that contacts the outside air, and the scent accompanying the wind may be changed according to the temperature based on the temperature information from the temperature sensor. In this case, for example, if the outside air temperature is 30 ° C. or more, the mint fragrance is accompanied by the wind with the mint fragrance that makes humans feel cool. For example, if the outside air temperature is 10 ° C. or lower, a sweet scent is perceived by the wind with a sweet scent that makes humans feel warm. For example, if the outside air temperature is 10 to 30 ° C., the scent of the forest (phytoncide) that humans feel as a natural scent is caused to accompany the wind. Thereby, a gentle wind for the user 5 can be provided.
　なお、本実施の形態では、シャッター５１の開閉を、風量の切替に合わせて開閉するようになっているが、シャッター５１が“開”状態になった直後には香料設置部５０から香りが導出されにくい。そのため、ゆらぎ制御プログラム１５において、香りを同伴させる風が発生する１秒前（この時間は、実験等により数値を設定することが望ましい）にシャッター５１を“開”状態とするようにしてもよい。 In the present embodiment, the shutter 51 is opened and closed in accordance with the switching of the air volume. However, immediately after the shutter 51 is in the “open” state, the fragrance is derived from the fragrance setting unit 50. It is hard to be done. Therefore, in the fluctuation control program 15, the shutter 51 may be in the “open” state 1 second before the wind accompanied by the scent is generated (it is desirable to set a numerical value for this time by experiment or the like). .
　また、前述では、シャッター５１を設けて、風量の切替に合わせてシャッター５１の開閉するようになっているが、シャッターを備えることなく、常時に香料設置部５０から香りが導出されるようにしてもよい。この場合、風量によって濃度が異なる香りを提供することができる。例えば、強上限風量２４の送風の間は風量が大きいため、沢山の香りがユーザーに届き、濃度の高い香りを提供できる。また、弱気流２１の送風の間は風量が小さいため、少量の香りがユーザーに届き、濃度の低い香りを提供することができる。これにより、複雑な機構を用いることなく、風の風量に応じた濃度の香りを風に同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザーに提供することができる。 In the above description, the shutter 51 is provided so that the shutter 51 is opened and closed in accordance with the switching of the air volume. However, the fragrance is always derived from the fragrance setting unit 50 without the shutter. Also good. In this case, it is possible to provide a scent having a different concentration depending on the air volume. For example, since the air volume is large during the blowing of the strong upper limit air volume 24, a large amount of scent reaches the user, and a highly concentrated scent can be provided. Moreover, since the air volume is small during the blowing of the weak airflow 21, a small amount of scent reaches the user, and a scent having a low concentration can be provided. Thereby, without using a complicated mechanism, it is possible to accompany the wind with a scent having a concentration corresponding to the volume of the wind, and it is possible to provide the user with a wind that feels more natural and a scent that feels nature.
　（実施の形態２）
　以下、本発明の実施の形態２について、図１０を参照しながら説明する。 (Embodiment 2)
The second embodiment of the present invention will be described below with reference to FIG.
　本発明の実施の形態２に係る扇風機３の構成は、図１から図４に示した実施の形態１のものと同様である。 The configuration of the electric fan 3 according to the second embodiment of the present invention is the same as that of the first embodiment shown in FIGS.
　本実施の形態においても、実施の形態１と同様にゆらぎ制御プログラム１５が、前述した自然の風の風速変化をユーザー５に与えられるように、モーター１２の回転数を変化させ、プロペラファン６から送風する風量を制御する。 Also in the present embodiment, as in the first embodiment, the fluctuation control program 15 changes the rotation speed of the motor 12 so that the natural wind speed change described above can be given to the user 5, and the propeller fan 6 Controls the amount of air blown.
　図１０は、本発明の実施の形態２に係る扇風機３のゆらぎ制御による風量変化のグラフである。図１０に示すように、扇風機３は、第２弱気流２９と強気流２２とを交互に発生させる。第２弱気流２９は、８００ｍ３／ｈから４００ｍ３／ｈの範囲で変動する風量で送風を行う。強気流２２は、第２弱気流２９の最大風量より大きい風量である１０００ｍ３／ｈで送風を行う。強気流２２については、実施の形態１と同様であり、強上限風量２４は１０００ｍ３／ｈであり、増加時間２６および減少時間２８は５秒である。第２弱気流２９は、最大風量である弱上限風量３０と、最小風量である弱下限風量３１とで構成されるゆらぎ気流である。本実施の形態は、弱上限風量３０を８００ｍ３／ｈに設定し、弱下限風量３１を４００ｍ３／ｈに設定した一例である。この構成により、ユーザー５が強気流２２と第２弱気流２９との間の風速の変化に加えて、第２弱気流２９の弱上限風量３０と弱下限風量３１との間の風速の変化も感じることができる。そのため、ユーザー５はより自然なゆらぎを感じることができる。 FIG. 10 is a graph of the change in air volume by fluctuation control of the electric fan 3 according to Embodiment 2 of the present invention. As shown in FIG. 10, the electric fan 3 alternately generates the second weak air flow 29 and the strong air flow 22. The second weak air flow 29 blows air with an air volume that fluctuates in the range of 800 m 3 / h to 400 m 3 / h. The strong air flow 22 blows air at 1000 m 3 / h, which is an air volume larger than the maximum air volume of the second weak air flow 29. The strong air flow 22 is the same as in the first embodiment, the strong upper air flow rate 24 is 1000 m 3 / h, and the increase time 26 and the decrease time 28 are 5 seconds. The second weak airflow 29 is a fluctuation airflow composed of a weak upper airflow 30 that is the maximum airflow and a weak lower airflow 31 that is the minimum airflow. This embodiment is an example in which the weak upper limit air volume 30 is set to 800 m 3 / h and the weak lower limit air volume 31 is set to 400 m 3 / h. With this configuration, in addition to the change in the wind speed between the strong air flow 22 and the second weak air flow 29, the user 5 also changes the wind speed between the weak upper limit air volume 30 and the weak lower limit air volume 31 of the second weak air flow 29. I can feel it. Therefore, the user 5 can feel more natural fluctuation.
　また、本実施の形態では、強開始風量２３を弱下限風量３１に設定した。すなわち、弱下限風量３１が強開始風量２３と同じである。仮に、弱上限風量３０を強開始風量２３に設定した場合に、風量変化幅２５が小さくなり、風速変化のない人工的な風であるとユーザー５が感じることがある。本実施の形態は、そのような事態を防止できる。風量変化幅２５を大きくすることで、強気流２２にて送風された風がユーザー５に到達した際、ユーザー５が自然の風に見られる大きな風速の変化を明確に感じることができるため、より自然なゆらぎを感じることができる。 Further, in the present embodiment, the strong start air volume 23 is set to the weak lower limit air volume 31. That is, the weak lower limit air volume 31 is the same as the strong start air volume 23. If the weak upper air volume 30 is set to the strong start air volume 23, the air volume change width 25 becomes small, and the user 5 may feel that the wind is an artificial wind with no wind speed change. The present embodiment can prevent such a situation. By increasing the air volume change width 25, when the wind blown by the strong air flow 22 reaches the user 5, the user 5 can clearly feel a large change in the wind speed seen in the natural wind. You can feel natural fluctuations.
　なお、弱上限風量３０の風量は８００ｍ３／ｈに限定されるものではなく、弱下限風量３１の風量も４００ｍ３／ｈに限定されるものではない。 The air volume of the weak upper limit air volume 30 is not limited to 800 m 3 / h, and the air volume of the weak lower limit air volume 31 is not limited to 400 m 3 / h.
　なお、強気流２２の風量は１０００ｍ３／ｈに限定されるものではない。 The air volume of the strong air flow 22 is not limited to 1000 m 3 / h.
　なお、強開始風量２３は、第２弱気流２９の弱下限風量３１以外でもよい。また、強開始風量２３は、ユーザー５の好みに応じてユーザー５が扇風機３の操作部の操作により適宜設定できる構成としても良い。 The strong start air volume 23 may be other than the weak lower limit air volume 31 of the second weak air flow 29. Moreover, the strong start air volume 23 is good also as a structure which the user 5 can set suitably by operation of the operation part of the electric fan 3 according to the user 5's liking.
　また、実施の形態１と同様に、強上限風量２４の風量で送風している場合、シャッター５１を“開”状態となるように信号出力部１７からシャッター５１へ信号を出力するようにしてもよい。さらに、強上限風量２４の風量で送風しない場合には、シャッター５１を“閉”状態となるように信号出力部１７からシャッター５１へ信号を出力するようにしてもよい。これにより、強上限風量２４の風量で送風している場合、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザー５に提供することができる。また、強上限風量２４の風に香りを同伴させるため、高濃度の香りが風に同伴され、ユーザーが香りを明確に感じることができる。更に、人間の鼻はずっと同じ香りを嗅ぎ続けると嗅覚疲労を起こすが、強上限風量２４の風の間のみ、香りが同伴されるため、嗅覚疲労の増加を抑制できる。 Similarly to the first embodiment, when the air is blown at the air flow with the strong upper air flow 24, a signal may be output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state. Good. Furthermore, when the air is not blown at the air flow with the strong upper air flow 24, a signal may be output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “closed” state. As a result, when the air is blown at the air volume of the strong upper limit air volume 24, the scent can be accompanied by the wind, and the wind that feels more natural fluctuation and the scent that feels nature can be provided to the user 5. Moreover, since a scent is accompanied by the wind of the strong upper limit air volume 24, a high concentration scent is accompanied by the wind, and the user can clearly feel the scent. Furthermore, when the human nose continues to smell the same scent, it causes olfactory fatigue. However, since the scent is accompanied only by the wind with the strong upper air volume 24, the increase in olfactory fatigue can be suppressed.
　また、弱下限風量３１の風量で送風している場合には、シャッター５１を“開”状態となるように信号出力部１７からシャッター５１へ信号を出力するようにしてもよい。さらに、弱気流２１で送風しない場合には、シャッター５１を“閉”状態となるように信号出力部１７からシャッター５１へ信号を出力するようにしてもよい。これにより、弱下限風量３１の風量で送風している場合には、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザーに提供することができる。 In addition, when the air is blown with the air volume of the weak lower limit air volume 31, a signal may be output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state. Further, when the weak air current 21 does not blow, a signal may be output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “closed” state. As a result, when the air is blown with the air volume of the weak lower limit air volume 31, the scent can be accompanied by the wind, and the wind that feels more natural fluctuation and the scent that feels nature can be provided to the user.
　（実施の形態３）
　以下、本発明の実施の形態３について、図１１を参照しながら説明する。 (Embodiment 3)
Hereinafter, a third embodiment of the present invention will be described with reference to FIG.
　本発明の実施の形態３に係る扇風機３の構成は、図１から図４に示した実施の形態１のものと同様である。 The configuration of the electric fan 3 according to the third embodiment of the present invention is the same as that of the first embodiment shown in FIGS.
　本実施の形態においても、実施の形態１と同様にゆらぎ制御プログラム１５が、前述した自然の風の風速変化をユーザーに与えられるように、モーター１２の回転数を変化させ、プロペラファン６から送風する風量を制御する。 Also in the present embodiment, the fluctuation control program 15 changes the rotational speed of the motor 12 so as to give the above-described natural wind speed change to the user in the same manner as in the first embodiment, and blows air from the propeller fan 6. Control the amount of air flow.
　図１１は、本発明の実施の形態３に係る送風装置のゆらぎ制御による風量変化のグラフである。図１１に示すように、扇風機３は第３弱気流３２と強気流２２とを交互に発生させる。第３弱気流３２は、２００ｍ３／ｈから４００ｍ３／ｈの範囲で変動する風量で送風を行う。強気流２２は、第３弱気流３２の最大風量より大きい風量である１０００ｍ３／ｈで送風を行う。強気流２２については、実施の形態１と同様であり、強上限風量２４は１０００ｍ３／ｈであり、増加時間２６および減少時間２８は５秒である。第３弱気流３２は、最大風量である第３弱上限風量３３と、最小風量である第３弱下限風量３４とで構成されるゆらぎ気流である。本実施の形態は、第３弱上限風量３３を４００ｍ３／ｈと設定し、第３弱下限風量３４を２００ｍ３／ｈと設定した一例である。２００ｍ３／ｈの風量は、扇風機３とユーザー５との距離が約２ｍの場合にユーザー５の位置で測定される風速に換算すると０．２ｍ／ｓである。 FIG. 11 is a graph of changes in the air volume by fluctuation control of the blower according to Embodiment 3 of the present invention. As shown in FIG. 11, the electric fan 3 alternately generates a third weak air current 32 and a strong air current 22. The third weak air flow 32 blows air with an air volume that fluctuates in a range of 200 m 3 / h to 400 m 3 / h. The strong air flow 22 blows air at 1000 m 3 / h, which is an air flow larger than the maximum air flow of the third weak air flow 32. The strong air flow 22 is the same as in the first embodiment, the strong upper air flow rate 24 is 1000 m 3 / h, and the increase time 26 and the decrease time 28 are 5 seconds. The third weak airflow 32 is a fluctuation airflow composed of a third weak upper limit air volume 33 that is the maximum air volume and a third weak lower limit air volume 34 that is the minimum air volume. The present embodiment is an example in which the third weak upper limit air volume 33 is set to 400 m 3 / h and the third weak upper limit air volume 34 is set to 200 m 3 / h. The air volume of 200 m 3 / h is 0.2 m / s when converted to the wind speed measured at the position of the user 5 when the distance between the fan 3 and the user 5 is about 2 m.
　本実施の形態では、ゆらぎ制御プログラム１５を設定する際、風量変化幅２５が、前述した自然の風の風速変化幅２０を満たすように、強開始風量２３を第３弱上限風量３３と第３弱下限風量３４との間で可変に調整した。つまり、強開始風量２３を調整することで、ユーザー５に弱気流２１および強気流２２が到達した際、風速変化幅２０が（特徴４）にて前述した０．４ｍ／ｓ以上、１．２ｍ／ｓ以下となるように風量変化幅２５を調整する。風速変化幅２０が０．４ｍ／ｓ未満の場合、ユーザー５が風速の変化を感じられず、風速が一定の人工的な風と感じてしまう。一方で、風速変化幅２０が１．２ｍ／ｓを超えて大きい場合、風による刺激の強さの急激な変化によりユーザー５を驚かす、または、が不快に感じさせるおそれがある。図１１において、仮に強開始風量２３を第３弱下限風量３４に設定した場合、風速変化幅２０は、１．４ｍ／ｓとなり、前述した１．２ｍ／ｓを超える。強上限風量２４はユーザー５へ到達する風速に換算すると１．６ｍ／ｓであり、第３弱下限風量３４はユーザー５へ到達する風速に換算すると０．２ｍ／ｓであるからである。このとき、風による刺激の強さの急激な変化によりユーザーを驚かす、または、不快に感じさせるおそれがある。したがって、図１１に示すように、強開始風量２３を第３弱上限風量３３に設定することで、風速変化幅２０を１．２ｍ／ｓに調整する。これにより、ユーザー５はより自然なゆらぎを感じることができる。 In the present embodiment, when the fluctuation control program 15 is set, the strong start air volume 23 is set to the third weak upper limit air volume 33 and the third air volume change width 25 so that the air volume change width 25 satisfies the natural wind speed change width 20 described above. It was variably adjusted with the weak lower limit air volume 34. That is, by adjusting the strong start air volume 23, when the weak air flow 21 and the strong air flow 22 reach the user 5, the wind speed change width 20 is 0.4 m / s or more and 1.2 m described above in (Feature 4). The air volume change width 25 is adjusted to be equal to or less than / s. When the wind speed change width 20 is less than 0.4 m / s, the user 5 cannot feel a change in the wind speed, and feels an artificial wind with a constant wind speed. On the other hand, when the wind speed change width 20 is larger than 1.2 m / s, there is a possibility that the user 5 may be surprised or uncomfortable due to a sudden change in the strength of the stimulation caused by the wind. In FIG. 11, if the strong start air volume 23 is set to the third weak lower limit air volume 34, the wind speed variation width 20 is 1.4 m / s, which exceeds the above-described 1.2 m / s. This is because the strong upper air volume 24 is 1.6 m / s when converted to the wind speed reaching the user 5, and the third weak lower limit air volume 34 is 0.2 m / s when converted to the wind speed reaching the user 5. At this time, the user may be surprised or uncomfortable due to a sudden change in the intensity of the stimulation caused by the wind. Therefore, as shown in FIG. 11, the wind speed variation width 20 is adjusted to 1.2 m / s by setting the strong start air volume 23 to the third weak upper limit air volume 33. Thereby, the user 5 can feel a more natural fluctuation.
　なお、第３弱気流３２の第３弱上限風量３３の風量は４００ｍ３／ｈに限定されるものではなく、第３弱下限風量３４の風量も２００ｍ３／ｈに限定されるものではない。 Note that the air volume of the third weak upper limit air volume 33 of the third weak air flow 32 is not limited to 400 m 3 / h, and the air volume of the third weak lower limit air volume 34 is not limited to 200 m 3 / h.
　なお、強気流２２の風量は１０００ｍ３／ｈに限定されるものではない。 The air volume of the strong air flow 22 is not limited to 1000 m 3 / h.
　また、実施の形態１と同様に、強上限風量２４の風量で送風している場合には、シャッター５１を“開”状態となるように信号出力部１７からシャッター５１へ信号を出力してもよい。そして、強上限風量２４の風量で送風しない場合には、シャッター５１を“閉”状態となるように信号出力部１７からシャッター５１へ信号を出力するようにしてもよい。これにより、強上限風量２４の送風の間、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザー５に提供することができる。また、強上限風量２４の送風に香りを同伴させるため、高濃度の香りが風に同伴され、ユーザー５が香りを明確に感じることができる。更に、人間の鼻はずっと同じ香りを嗅ぎ続けると嗅覚疲労を起こすが、強上限風量２４の送風の間のみ、香りが同伴されるため、嗅覚疲労の増加を抑制できる。 Similarly to the first embodiment, when the air is blown at the air flow with the strong upper air flow 24, a signal is output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state. Good. And when not blowing with the air volume of the strong upper limit air volume 24, a signal may be output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “closed” state. Thereby, a fragrance can be accompanied by the wind during the blowing of the strong upper limit air volume 24, and a wind that feels more natural fluctuation and a fragrance that feels nature can be provided to the user 5. Moreover, since a scent is accompanied by the airflow of the strong upper limit air volume 24, a high concentration scent is accompanied by the wind, and the user 5 can clearly feel the scent. Furthermore, when the human nose continues to smell the same scent, it causes olfactory fatigue. However, since the scent is accompanied only during the blowing of the strong upper air volume 24, an increase in olfactory fatigue can be suppressed.
　また、第３弱下限風量３４の風量で送風している間、シャッター５１を“開”状態となるように信号出力部１７からシャッター５１へ信号を出力してもよい。そして、弱気流２１で送風しない場合には、シャッター５１を“閉”状態となるように信号出力部１７からシャッター５１へ信号を出力するようにしてもよい。これにより、第３弱下限風量３４の風量で送風している間、風に香りを同伴させることができ、より自然なゆらぎと感じる風と自然を感じる香りをユーザー５に提供することができる。 Further, a signal may be output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in an “open” state while the air is blown at the third weak lower limit air volume 34. And when not blowing with the weak airflow 21, you may make it output a signal from the signal output part 17 to the shutter 51 so that the shutter 51 may be in a "closed" state. Thereby, while blowing with the air volume of the third weak lower limit air volume 34, the scent can be accompanied with the wind, and the wind that feels more natural fluctuation and the scent that feels nature can be provided to the user 5.
　以上のように本発明にかかる送風装置およびゆらぎ制御プログラムは、より自然なゆらぎを感じる風と自然な香りをユーザーに提供することを可能とするものであるので、空気調和機、扇風機、天井扇等の送風機器全般に有用である。 As described above, the air blower and the fluctuation control program according to the present invention can provide the user with a wind and a natural scent that feels more natural fluctuations. Therefore, an air conditioner, a fan, and a ceiling fan are provided. It is useful for general blower equipment.
