Description

  The present invention relates to a blower that blows air so that the amount of blown air fluctuates, and a device that provides a scent in a blow control program.

  In order to improve the comfort of the indoor space, 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).

  Hereinafter, the ventilation control program at the time of ventilation of the air conditioner will be described with reference to FIG.

  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 rotational speed of the fan is smaller than that of the first air blowing pattern 102, and the rotation of the fan. It is something that changes the number. 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. Thereby, by combining the 2nd ventilation pattern 104 with small change of ventilation volume, and the 1st ventilation pattern 103 with large change of ventilation volume alternately, compared with the case where a 1st ventilation pattern continues continuously, ventilation volume of The change width can be reduced, and the difference between the ideal fan air flow rate and the actual fan air flow rate is less likely to occur.

  See Patent Document 1 below as a prior document.

JP 2114-66485 A

  In the above-described conventional example, the fluctuation control for reducing the change amount of the air flow rate by alternately combining the second air blowing pattern 104 with the small air flow rate change and the first air blowing pattern 103 with the large air flow rate change is described. Yes. However, as a problem of the conventional example, when shifting from the second air blowing pattern to the first air blowing pattern 103, there is a problem that the user feels an artificial wind without a change in the wind speed because the change width of the air blowing amount becomes small. there were.

  That is, the fluctuation control program of the conventional example has 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. 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.

  In order to achieve this object, the present invention is a blower device having a blower control that alternately generates a weak airflow that blows a small airflow and a strong airflow that blows a large airflow, and derives a scent. A scent generating means is provided, and the air flow control is a difference between a strong air flow transition air amount that is a weak air flow amount when transitioning from the weak air flow to the strong air flow and a strong upper air flow amount that is the maximum air flow of the strong air flow. A certain air volume change width can be set in advance, and the scent derived from the scent generating means is accompanied by the wind of the strong upper air volume during the strong upper air volume which is the maximum air volume of the strong air current. This achieves the intended purpose.

  According to the present invention, there is provided a blower device including a blower control that alternately generates a weak airflow that blows a small amount of air and a strong airflow that blows a large amount of air. The air flow control is capable of presetting an air volume change width that is a difference between an air volume of the weak air current when shifting from the weak air current to the strong air current and a strong upper air volume that is a maximum air volume of the strong air current, During the strong upper air flow, the scent derived from the scent generating means is accompanied by the strong upper air flow, thereby allowing the scent to accompany the wind during the strong upper air flow, It is possible to provide users 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.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment described below exemplifies a blower device for embodying the technical idea of the present invention, and the present invention does not specify the blower device as follows. Moreover, the member shown by the claim is not what specifies the member of an Example at all. In particular, the dimensions, materials, shapes, relative arrangements, and the like of the constituent members described in the embodiments are not intended to limit the scope of the present invention only to the description unless otherwise specified. It is just an example. Note that the size, positional relationship, and the like of the members shown in each drawing may be exaggerated for clarity of explanation.

  The blower device according to claim 1 of the present invention is a blower device including a blower control that alternately generates a weak air flow that blows a small amount of air and a strong air flow that blows a large amount of air, and a scent that derives a scent. A generating means is provided, and the air flow control is an air volume change width that is a difference between a strong air flow transition air volume that is an air volume of a weak air current when transitioning from a weak air current to a strong air current and a strong upper air volume that is a maximum air volume of the strong air current. Can be set in advance, and the scent derived from the scent generating means is accompanied by the strong upper air volume during the strong upper air volume that is the maximum air volume of the strong air current. This prevents the user from feeling that the wind is an artificial wind with no change in the wind speed, and ensures that the user feels a large change in the wind speed seen in the natural wind. It is possible to bring a scent into the wind and 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 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.

  Further, the blower device includes a blower control that alternately generates a weak air flow that blows a small amount of air and a strong air flow that blows a large amount of air. It is possible to set in advance an airflow change width that is a difference between a strong airflow transition airflow that is an airflow of a weak airflow when transitioning from the weak airflow to the strong airflow, and a strong upper airflow that is a maximum airflow of the strong airflow, During the weak air flow that blows a small amount of air, the scent derived from the scent generating means is accompanied with the weak air flow. Thereby, a fragrance can be accompanied by a wind during a weak air current, and a wind that feels more natural fluctuations and a scent that feels nature can be provided to the user 5. 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.

  Further, the blower device includes a blower control that alternately generates a weak air flow that blows a small amount of air and a strong air flow that blows a large amount of air. It is possible to set in advance an airflow change width that is a difference between a strong airflow transition airflow that is an airflow of a weak airflow when transitioning from the weak airflow to the strong airflow, and a strong upper airflow that is a maximum airflow of the strong airflow, The scent derived from the scent generating means is accompanied by the weak air current and the 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.

The electric fan 3 directs the air in the room 1 to the user 5 and blows a wind like a natural fluctuation, and provides the user 5 with comfort and comfort that can be felt from the natural wind.

  FIG. 2 is a front view illustrating a configuration example of the electric fan 3. The electric fan 3 includes a propeller fan 6 for blowing wind and a support body 7 that fixes the propeller fan 6 at a certain height.

  FIG. 3 is a cross-sectional view showing a cross section AA ′ of the electric fan 3. The propeller fan 6 has a rotating body 8 that is a rotating shaft, a blade 9 that is a member connected to the rotating body 8 and generates a pressure difference in the air by rotating, and the blade 9 and the user 5 are in contact with each other. It is comprised from the guard 10 which is a member which prevents this, and the power part 11 which supplies motive power to a rotary body. The power unit 11 includes a motor 12 that supplies power to the rotating body 8, a control board 13 that controls the rotation speed of the motor 12, and a signal line 14 that passes signals between the control board 13 and the motor 12. It consists of 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 a signal transmitted from the control board 13.

  FIG. 4 is a block diagram showing the configuration of the control system of the motor 12 inside the control board 13. The control board 13 outputs to the motor 12 a microcomputer 16 that stores a fluctuation control program 15 that is a program for changing the rotational speed of the motor 12 in a preset time series, and the fluctuation control program 15 stored in the microcomputer 16. And a signal output unit 17. That is, the control board 13 sends a signal based on the fluctuation control program 15 to the motor 12 via the signal line 14, thereby changing the rotational speed of the motor 12 in time series and changing the amount of air blown to the user 5. be able to.

  With this configuration, in the present embodiment, the control board 13 controls the motor 12 so that the wind blown from the electric fan 3 can be felt by the user like a natural fluctuation wind.

  Here, the characteristics of natural wind will be described with reference to FIGS. FIG. 5 is a graph showing time-series changes in wind speed obtained when natural wind is measured by an anemometer. FIG. 6 is an enlarged view of section B shown in FIG.

  (Characteristic 1) As shown in FIG. 5, the wind speed of the natural wind always changes in time series, and the change range is from 0.1 m / s to 1.8 m / s.

  (Characteristic 2)) As shown in FIG. 5, the period in which the large waveform 18 which is a waveform of a large wind speed exceeding 1.0 m / s is observed is in the range of 10 s to 300 s. Details of natural wind will be described with reference to FIG.

  (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. .

  (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. .

  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.

  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.

FIG. 7 is a graph showing changes in the air volume of the electric fan 3 according to the first 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, the wind speed measured when the distance between the fan 3 and the user 5 is about 2 m is 0.4 m / s for the weak air flow 21 and 1.6 m / s for the strong air flow 22. The airflows of the weak airflow 21 and the strong airflow 22 are the strong airflow transition airflow 23 that is the airflow of the weak airflow 21 when the weak airflow 21 is transferred to the strong airflow 22, and the strong upper airflow that is the maximum airflow of the strong airflow 22. It is set based on the air volume change width 25 which is a difference from 24. 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.

  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 variation width of 1.2 m / s. Therefore, by performing the weak air flow 21 and the strong air flow 22 alternately on the basis of the air flow rate change width 25 that satisfies the wind speed change width 20 found in the natural wind, the user 5 can determine that the artificial wind has no wind speed change. It is possible to prevent the user 5 from feeling, and to surely make the user 5 feel the large change in wind speed seen in the natural wind. Thereby, the wind which feels a natural fluctuation can be provided to the user 5.

  Further, as shown in FIG. 7, an increase time 26 that is a time required to reach the strong upper airflow 24 from the strong airflow 23 is preset. 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. Thereby, it is possible to prevent the user 5 from getting used to the change in the wind speed due to the long time required to increase or decrease the air volume and to feel the artificial wind without the change in the wind speed. In addition, since the time required for the increase and decrease of the air volume is short, the intensity of the stimulation caused by the wind is abruptly changed to prevent a surprised user from feeling uncomfortable. At this time, the increase time 26 and the decrease time 28 were set to 5 seconds.

  The signal line 14 may perform wireless communication in addition to connection using a wired cord.

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.

  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.

  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.

  Next, a case where a natural scent is also provided when the wind that feels the natural fluctuation described above is provided will be described.

  FIG. 8 is a cross-sectional view showing the power unit 11 located particularly behind the guard 10 in the A-A ′ cross section in the case where the air blowing device according to Embodiment 1 is provided with means for providing a scent.

  In FIG. 8, 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, and a shutter 51 for deriving the scent from the fragrance installation unit 50 to the outside. The control board 13 in the power unit 11 is provided with a signal line 14 for transferring signals between the control board 13 and the shutter 51, and the control board 13 causes the rotation speed of the motor 12 and the opening / closing of the shutter 51. To control. 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.

  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.

  FIG. 9 is a functional block diagram showing the configuration of the control system of the motor 51 and the shutter 51 for deriving the scent inside the control board 13.

  The control board 13 includes a microcomputer 16 that stores a fluctuation control program 15 that is a program for changing the rotational speed of the motor 12 in a preset time series, and a signal based on the fluctuation control program 15 stored in the microcomputer 16. 12 and a signal output unit 17 that outputs to 12. The microcomputer 16 also stores a program for opening and closing the shutter 51 in accordance with the change in the rotational speed of the motor 12 as the fluctuation control program 15, and the signal output unit 17 stores the fluctuation control program stored in the microcomputer 16. 15 is also output 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 changing the rotation speed of the motor 12 in time series and the amount of air blown to the user 5. The scent can be changed by opening and closing the shutter 51 in accordance with the change in the air flow. Note that the shutter 51 is opened and closed by moving the shutter 51 in a double-headed arrow (vertical direction in FIG. 8). When the shutter 51 moves downward, the shutter 51 moves to the “open” state. It becomes a state. 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.

  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.

  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 while the air is being blown with the air flow of the strong upper air flow 24 in FIG. When the air is not blown with the air volume, a signal is output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “closed” state. When the shutter 51 is in the “open” state, the scent is derived from the fragrance stored in the fragrance setting unit 50 in the direction of the broken line arrow, and the rotating body 8 and the blades are in front of the power unit 11 (in the direction of the broken line arrow). 9 (refer to FIG. 3), the scent can be accompanied by the blowing air. 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.

  Thereby, a scent can be caused to accompany the wind during the blowing of a strong upper limit air volume, and a wind that feels more natural fluctuations 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.

  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 “open” state while the air is blown with the airflow of the weak airflow 21 in FIG. When the air is not blown, a signal may be output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in a “closed” state. 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, if 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.

  The power unit 11 includes a plurality of fragrance setting units 50 and shutters 51, which are scent generating means, and the fragrance setting unit 50 stores different fragrances, and the control board 13 is the same as described above. A shutter opening / closing operation is performed, and different scents can be caused to accompany the wind amount of the strong upper limit air amount 24 and the air amount of the weak air flow 21 in FIG. As a result, when the human nose keeps sniffing the same scent for a long time, it causes olfactory fatigue. However, since different scents are accompanied by the high upper air flow rate and the weak air flow rate, an increase in olfactory fatigue can be suppressed.

  In addition, the power unit 11 includes a plurality of fragrance setting units 50 and shutters 51 that are scent generating means, and the fragrance setting unit 50 stores different fragrances, and the microcomputer 16 of the control board 13 has a clock. By providing the function, the scent accompanying the wind may be changed according to the season and time zone.

  Further, 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 temperature information from the temperature sensor. In this case, for example, if the outside air temperature is 30 ° C. or higher, the mint fragrance that makes humans feel cool is accompanied by the scent of mint, and if the outside air temperature is 10 ° C. or lower, humans feel the warmth. A fragrant fragrance that brings sweet scent to the wind, and if the outside air temperature is 10 to 30 ° C, it provides a gentle wind to the user by bringing the scent of the forest (phytoncide) that humans feel as a natural scent to the wind. can do.

  In the first embodiment, the shutter 51 is opened and closed in accordance with the switching of the air volume. However, the fragrance is derived from the fragrance setting unit 50 immediately after the shutter 51 is in the “open” state. Therefore, in the fluctuation control program 15, the shutter 51 is set to the “open” state 1 second before the generation of the scent-entraining wind (it is desirable to set a numerical value for this time by experiment or the like). Also good.

In the above description, the shutter 51 is provided so that the shutter 51 opens and closes in accordance with the switching of the air volume. However, the fragrance is always derived from the fragrance setting unit 50 without the shutter. In this case, it is possible to provide a scent having a different concentration depending on the air volume. For example, the amount of air flow is large during the air flow with a strong upper limit, so a lot of fragrance can reach the user and provide a high concentration of scent. , Can provide a low concentration scent. 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.
(Embodiment 2)
The second embodiment of the present invention will be described below with reference to FIG.

  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.

  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.

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, 1000 m fan 3 and the second weak stream 29 which air volume air is blown in the range of 400 meters ³ / h from 800 m ³ / h, the maximum air volume is larger than air volume of the second bearish stream 29 ³ / The strong air flow 22 that blows air at h is alternately performed. 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, since the user 5 can feel the change in the wind speed of the weak air current 21 in addition to the change in the wind speed due to the strong air current 22, the user 5 can feel a more natural fluctuation.

  Further, in the present embodiment, the strong airflow transition air volume 23 is set to the weak lower limit air volume 31. Thereby, when the weak upper limit air volume 30 is set to the strong airflow transition air volume 23, the air volume change width 25 is reduced, and the user 5 can be prevented from feeling that the wind is an artificial wind having no wind speed change. Therefore, 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 wind speed seen in natural wind. , You can feel more natural fluctuations.

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.

The air volume of the strong air flow 22 is not limited to 1000 m ³ / h.

  The strong airflow transition air volume 23 may be other than the weak lower limit air volume 31 of the second weak airflow 29, and may be configured to be appropriately set according to the user's preference.

  Similarly to the first embodiment, a signal is output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state while the air is blown at the air flow of the strong upper air flow 24, and the strong upper air flow is When the air flow is not 24, the signal output unit 17 may output a signal to the shutter 51 so that the shutter 51 is in the “closed” state. Thereby, a scent can be caused to accompany the wind during the blowing of a strong upper limit air volume, and a wind that feels more natural fluctuations 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.

When the air is blown with the air flow of the weak lower limit air flow 31, a signal is output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state. A signal may be output from the signal output unit 17 to the shutter 51 so that 51 is in a “closed” state. Thereby, while blowing with the air volume of the weak lower limit air volume 31, it is possible to bring a scent into the wind, and to provide the user with a wind that feels more natural fluctuations and a scent that feels nature. (Embodiment 3)
Hereinafter, a third embodiment of the present invention will be described with reference to FIG.

  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.

  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.

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, 1000 m fan 3 and the third bearish stream 32 for blowing air in the range air volume from 200 meters ³ / h of 400 meters ³ / h, the maximum air volume is larger than air volume of the third bearish flow 32 ³ / The strong air flow 22 that blows air at h is alternately performed. 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. At this time, when the third weak lower limit air volume 34 is 200 m ³ / h, the wind speed measured at a position where the distance between the fan 3 and the user 5 is about 2 m is 0.2 m / s.

  In the present embodiment, when the fluctuation control program 15 is set, the strong airflow transition air volume 23 is set to the weak upper limit air volume 30 and the weak lower limit air volume so that the air volume change width 25 satisfies the natural wind speed change width 20 described above. 31 and variably adjusted. That is, by adjusting the strong airflow transition air volume 23, when the weak airflow 21 and the strong airflow 22 reach the user 5, the wind speed change width 20 is 0.4 m / s or more as described in (Feature 4). The air volume change width 25 is adjusted so as to be 2 m / s or less. This is because when the wind speed change width 20 is less than 0.4 m / s, the user 5 cannot feel the 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 large exceeding 1.2 m / s, the intensity of the stimulation by the wind changes abruptly, and a surprised user may feel uncomfortable. In FIG. 9, if the strong airflow transition air volume 23 is set to the third weak lower limit air volume 34, the strong upper limit air volume 24 is 1.6 m / s at the wind speed reaching the user 5, and the third weak lower limit air volume 34 is the user. Since the wind speed reaching 5 is 0.2 m / s, the wind speed variation width 20 is 1.4 m / s, which exceeds the above-described 1.2 m / s. At this time, the intensity of the stimulation caused by the wind changes rapidly, and a surprised user may feel uncomfortable. Therefore, as shown in FIG. 9, by setting the strong airflow transition air volume 23 to the third weak upper limit air volume 33, the wind speed variation width 20 can be adjusted to 1.2 m / s, and the user 5 feels more natural fluctuations. be able to.

In addition, the air volume of the third weak upper limit air volume 33 of the third weak air flow 32 is not limited to 800 m ³ / h, and the air volume of the third weak lower limit air volume 34 is not limited to 400 m ³ / h.

The air volume of the strong air flow 22 is not limited to 1000 m ³ / h.

  Similarly to the first embodiment, a signal is output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state while the air is blown at the air flow of the strong upper air flow 24, and the strong upper air flow is When the air flow is not 24, the signal output unit 17 may output a signal to the shutter 51 so that the shutter 51 is in the “closed” state. Thereby, a scent can be caused to accompany the wind during the blowing of a strong upper limit air volume, and a wind that feels more natural fluctuations 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.

  Further, when the air is blown with the third weak lower limit air volume 34, a signal is output from the signal output unit 17 to the shutter 51 so that the shutter 51 is in the “open” state, and the weak air flow 21 does not blow. The signal output unit 17 may output a signal to the shutter 51 so that the shutter 51 is in the “closed” state. Thereby, while blowing with the air volume of the third weak lower limit air volume 34, 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.

  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.
