Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an environment control device for controlling an environment for work.

[0002]

2. Description of the Related Art The working environment is prepared by a lighting device, an air conditioner, or the like that secures the brightness for the work, and the lighting device for this purpose provides the work surface with the illuminance required for the work. It could only be secured. Also, air conditioners and other equipment were only designed to keep the temperature and humidity comfortable.

[0003]

By the way, in desk work, office work, monitoring of factory machinery, work in a production line or a central control room of a nuclear power plant, etc., when the work is monotonous or due to a biological rhythm, In the time period when the power falls (for example, from 1 pm to 4 pm or from 3 am to 5 am), it is more likely that the arousal level will decrease and work performance will decrease, and mistakes that will lead to an accident will occur. .

As disclosed in Japanese Patent Application Laid-Open No. 4-4506, as a means for increasing the arousal level, the brightness level is kept considerably higher than the brightness required for work, so that the arousal level can be increased. However, if such brightness continues, the wakefulness may decrease due to habituation. Further, since it is difficult to keep the entire work environment at the brightness as described above, it is extremely difficult to always keep the arousal level high only by ensuring the brightness.

The present invention has been made in view of the above points, and an object of the present invention is to provide an environment control device capable of maintaining a high awakening level during work.

[0006]

SUMMARY OF THE INVENTION The environment control device according to the present invention, however, alternates between a standard illuminance period that provides an illuminance suitable for work and a high illuminance period that provides an illuminance higher than that in the standard illuminance period. Lighting device to develop in
It is characterized by being composed of a stimulator that changes at least one of wind, sound, vibration and incense. By not returning to the high illuminance period but returning to the standard illuminance period and then causing the high illuminance period again, it is possible to prevent a decrease in arousal level due to habituation and to improve the arousal level for a long period of time due to the appearance of the high illuminance period. In addition to the change in illuminance, the operator's eyes can be closed by using a stimulus by changing at least one of temperature, humidity, wind, sound, vibration, and incense in addition to the change in illuminance. It is possible to increase the alertness even when the time or the attention of the worker is outside the illuminated area.

At least one change of temperature, humidity, wind, sound, vibration, and incense by the stimulator is made at the same time or almost at the same time as the illuminance change by the illuminating device. It is preferable in that it can be added efficiently.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an example of an embodiment of the present invention, FIG. 1 shows an example of an embodiment of the present invention. Illumination device 2, air conditioner 3, aroma generating device 4,
The vibration generator 5 and the control device 1 to which the timer 10 is connected
Is under the control of. The illuminating device 2 here has an illuminance suitable for the work and about 1.5 times or more than this illuminance.
Preferably, it is possible to selectively provide an illuminance of twice or more. For example, when the illuminance suitable for the work (work surface illuminance) is 1000 lux, 1500 lux or more, and preferably 2000 lux or more can be used. Then, under the control of the control device 1, the standard illuminance period that provides the illuminance suitable for the work and the high illuminance period that provides the higher illuminance can be alternately displayed.

FIG. 2 shows an example of a work environment controlled by the environment control device. The lighting device 2 is a ceiling lighting device 20.
And the local lighting unit 21, the standard illuminance period in which the illuminance on the desk 14 is an illuminance suitable for work can be obtained by turning on the ceiling lighting unit 20, which is a general lighting unit, and the irradiation direction is It is possible to obtain a high illuminance period by further lighting or dimming the local illuminator 21 on the desk surface. This is because when the ceiling illuminator 20 that performs general illumination alone is used to obtain a high illuminance period in which the work surface of each worker has high illuminance, the ceiling illuminator 20
In addition to the extremely large output value required for, it would have been possible to raise only the illuminance of the work surface, whereas it would raise the illuminance of unnecessary parts, resulting in unnecessary energy consumption. Occurs,
As the ceiling illuminator 20, one that can provide the illuminance necessary for the standard illuminance period is used, and the illuminance during the high illuminance period is supported by lighting the local illuminator 21. In addition to turning on / off the local illuminator 20, the ceiling illuminator 20 is also dimmed to prevent the illuminance from changing.

From the air conditioning outlet 30, not only the air of the temperature and humidity controlled by the air conditioner 3 is blown out, but also the scent generated by the aroma generating device 4 is also blown out. Further, the vibration generator 5 is incorporated in the chair 50 on which the worker sits, and its operation allows the worker to vibrate.

In FIG. 3, a lighting device 2, an air conditioner 3, an aroma generating device 4 and a sound generating device 6 are used as the devices under the control of the control device 1, and the air conditioner 3 is also remote from the air volume control. It uses a controllable one. FIG. 4 shows an example of a work environment controlled by the environment control device. In the work space partitioned by the partition 15, the front partition 15 has an air-conditioning outlet through which the scent of the fragrance generating device 4 comes out. 30 and
A lighting device 22 that is dimmable and a sound generator 6
And a speaker 60 which is an output part of the.

FIG. 5 shows an air blowing device 7 capable of adjusting the air volume, an aroma generating device 4, a lighting device 2, and a sound generating device 6 under the control of the control device 1. FIG. An example is shown in which the blower 7, the aroma generating device 4, and the voice generating device 6 are incorporated in the base of the stand-type lighting fixture 23 that is the device 2, and the incense and wind blowing ports 70 and the speaker 60 are arranged on the front surface of the base. There is.

In such an environment control device, however, the control device 1 performs the individual control or dimming of the illuminating device 2 at a predetermined cycle or a random cycle of about 3 to 15 minutes. The standard illuminance period and the high illuminance period are alternately displayed, and in synchronization with the transition from the standard illuminance period to the high illuminance period, the temperature or humidity or the air volume at the place by the air conditioner 3 is changed, The aroma generating device 4 generates a scent, the vibration generating device 5 generates a vibration, the sound generating device 6 emits a sound, and the blowing device 7 starts blowing air or increases the air volume.

The air conditioner 3 has a temperature of 25 ° C. and a relative humidity of 5
When the normal setting is 0%, it is preferable that the temperature shifts to a temperature of 22 ° C. and a relative humidity of 30% in the high illuminance period. In the case where the air volume is also adjusted, it is preferable to increase the air volume in synchronization with the high illuminance period. As the aroma generating device 4, a device generating a refreshing aroma such as mint can be preferably used. Voice generator 6
May be a single tone of several 100 Hz. As the blower 7, a blower that emits a slight wind of about several m / s in the high illuminance period can be used.

FIG. 7 shows an operation example in the case where the stimulating devices 3, 4, 5, 6, 7 are operated in synchronization with changes in illuminance by the illuminating device 2. The illuminance change from the standard illuminance period to the high illuminance period is dealt with by rapidly increasing the illuminance, and this is preferable, but the illuminance transition from the high illuminance period to the standard illuminance period gradually decreases the illuminance. You may go by that. The same applies to other stimuli.

Regarding the expression interval in the high illuminance period, it is desirable to develop the high illuminance period between 3 minutes and 15 minutes because the arousal level decreases when the same illuminance continues for about 10 minutes. May be constant, but from 3 minutes to 1
Random changes during the 5-minute time interval make it impossible for the user to predict the onset interval during the high illuminance period, and thus a further awakening effect can be expected.

[0017]

As described above, in the present invention, the standard illuminance period that provides the illuminance suitable for the work and the high illuminance period that provides the illuminance higher than that in the standard illuminance period are alternately displayed. In addition to changing the illuminance, at least one of temperature, humidity, wind, sound, vibration and incense should not be changed, as the wakefulness effect due to the appearance of the high illuminance period does not decrease due to habituation. Since the stimulus by is added, the arousal effect is higher, and it is possible to maintain a high arousal level for a long time,
The arousal level can be increased even when the operator's eyes are closed or when the operator's attention is outside the illuminated area.

Further, if at least one of temperature, humidity, wind, sound, vibration, and incense by the stimulator is changed at the same time or almost at the same time as the illuminance change by the illuminator, the awakening effect by each stimulus is effective. Since the sum is efficiently added, the high alertness can be maintained more effectively.
