  A falling ceiling 21 is provided above the beds 20 and 20. That is, a ceiling that is lower than the ceiling of the bedroom is provided. By providing the falling ceiling 21, the ceiling becomes closer to the sleeping person sleeping on the bed 20, and the sleeping person can obtain an appropriate feeling of pressure, and an environment in which psychologically easy to fall asleep is formed.

  And the rail 26 for the curtain 27 which encloses the circumference | surroundings of each bed 20 * 20 is provided in the ceiling surface of the said falling ceiling 21. As shown in FIG. The curtain 27 suspended from the rail 26 enables the beds 20 and 20 in the same room to be arranged in independent spaces.

The curtain 27 is made of a semi-transparent cloth material such as lace, and while the space is visually softly defined, leakage of light, propagation of sound and the outside of the space surrounded by the curtain 27 The outflow of the airflow is suppressed, and an independent sleep environment can be formed in the space surrounded by the curtain 27.
In this way, by forming an individual sleeping environment for the sleeping person, even if they are in the same bedroom, even if there is a difference in sleeping environment suitable for each sleeping person or a difference in the living time of each sleeping person, Therefore, it is possible to prepare a sleep environment suitable for individual sleepers without being bothered.

  Air conditioning means 18 is configured inside the falling ceiling 21. And the blower outlet of the cold air or warm air from this air-conditioning means 18 is each provided in the ceiling surface (air outlet 30 * 30) of the falling ceiling 21, and the headboard 22 (air outlet 29) of the said bed 20. .

The temperature in the space defined by the curtain 27 is adjusted by cold air or hot air blown from the outlet 30 of the falling ceiling 21. That is, it is possible to adjust the temperature of the “1.5th order sleep environment” shown in FIG.
Further, the head of the sleeping person can be cooled by the cold air or the hot air blown from the air outlet 29 of the headboard 22, and the temperature environment of “foot warm head cooling” suitable for sleep can be formed. it can.

The storage 25 is provided with sound generating means 16 such as an audio player. The vibrator constituting the output unit of the sound generating unit 16 is attached to the head board 22 of the bed 20, and the head board 22 functions as a speaker that is the output unit of the sound generating unit 16.
As a result, sound is generated from the entire headboard 22, and the sleeper is wrapped in a sound that is drawn into sleep.

  In addition, an illumination device 14 </ b> A serving as the light generation means 14 is provided inside the head board 22 of the bed 20. In this illuminating device 14A, light is generated from a light bulb-colored fluorescent lamp that is an image of night light, and the illuminance of the generated light can be changed. The light emitted from the illuminating device 14A illuminates the surroundings of the headboard 22 and becomes indirect illumination for the sleeping person. During the relaxing time before going to bed, the lighting device 14A can be turned on to relax the feelings for sleep preparation.

  On the other hand, an illuminating device 14B as the light generating means 14 is provided above the illuminating device 14A. In this illuminating device 14B, light is generated from a daylight white fluorescent lamp that is imaged of morning or noon light, and the illuminance of the generated light can be changed. When the user wakes up, the lighting device 14B can be turned on to prepare the sleeper's body to wake up, and can also be used as a reading light at night.

  Next, control of the sleep environment adjustment system 10 having the above configuration will be described.

The control means 11 is adjusted by a sleep time, a wake-up time, a sound volume generated when the sound is generated by the sound generation means 16 (wake-up set sound volume), and a cold or hot air generated by the air-conditioning means 18. The temperature (standard set temperature) is preset. Although these are all arbitrary values, it is desirable that the wake-up setting sound volume be a sound that cannot be heard by others sleeping in the same room.
Further, a light sleep preliminary time, a light sleep preliminary time, a sound sleep preliminary time, a sound sleep preliminary time, a temperature sleep preliminary time, and a temperature sleep preliminary time, which will be described later, are all set in advance in the control means 11.

First, the control of the sleep environment adjustment system 10 during sleep onset will be described.
As shown in FIG. 5 and FIG. 6, when the time measuring means 12 detects that the “temperature sleep preparation time” is ahead of the set sleep time (S 30), the control means 11 17 sleep control is started (S31).

  When the sleep control is started, the temperature control means 17 generates cool air or warm air from the air conditioning means 18, and changes the temperature in the space (1.5th sleep environment) defined by the curtain 27 to the sleep time. The temperature is continuously reduced from the standard set temperature by about 3 ° C. over a period of time for sleep preparation. As a result, the temperature of the space defined by the curtain 27 is about 3 ° C. lower than the standard set temperature at the time of sleep.

The temperature sleep preparation time is the time taken to shift from the standard set temperature to the sleep temperature, and is about 4 hours.
Setting the start time of the sleep control by the temperature control means 17 to be approximately 4 hours before the sleep time requires approximately 4 hours to adjust the body temperature of the sleeper suitable for sleeping. If it is too short, the body temperature of the sleeper cannot be adjusted to the temperature change of the environment, and the sleeper may feel uncomfortable (chilly). If it is too long, the sleeper's body is ready to sleep. This is because the sleeper's activities are dulled by starting too early.
However, since the time required for bedtime preparation differs somewhat depending on the individual bedtime, it is possible to set an appropriate time for the bedtime of 1 to 5 hours as the temperature sleep preparation time.

  Subsequently, when the time measuring means 12 detects that the set sleep time is reached (S32), the control means 11 starts the sleep control of the light control means 13 (S33) and the sound control means 15 Sleep control is started (S34).

  When the sleep control is started, the light control unit 13 turns on the illuminating device 14 </ b> A that generates light bulb-colored light in the image of the night light in the light generation unit 14 and sets the illuminance to “sleeping illuminance”. In addition, several hours before falling asleep, the lighting device 14A that generates light bulb-colored light is turned on, the illuminance is set to “sleeping illuminance”, and the illuminance is continuously set to “sleeping illuminance” until the sleep time. It is preferable to change up to.

The sleep illuminance is about 30 lux.
This is because if the illuminance is greater than 30 lux, it is difficult for the sleeper to feel dazzled and fall asleep. Also, if the illuminance is a value smaller than 30 lux, the sleeper feels uncomfortable as if it was dark enough to be unable to act rapidly. However, the sleep illuminance is not strictly 30 lux, and an illuminance of 20 to 40 lux can be set.
The sleep preparation illuminance is about 100 lux. This is because the illuminance of 100 lux is suitable for taking a sleeper's mind and body into sleep preparation.

  As described above, in the sleep control of the light control means 13, the illuminance of the light emitted from the lighting device 14B, which is the light generation means 14, is reduced to the sleep illuminance at the sleep time. Then, the light control means 13 reduces the illuminance of the light emitted from the illuminating device 14B, which is the light generating means 14, continuously from the sleep time to about 0 lux over the “light sleep preliminary time”, and turns off the light. That is, the light emitted by the light generating means 14 fades out over the light sleep time from the sleep time.

The light sleep preliminary time is the time from sleep time to light extinction, and is about 10 minutes.
If the time from sleep time to light-off is too short, the sleeper may quickly become dark before going to sleep and may feel uncomfortable. Therefore, it is appropriate that the light sleep preliminary time is about 10 minutes.
However, since the time required to fall asleep differs depending on the sleeper, it is possible to set an appropriate time between 5 and 30 minutes as the light sleep preliminary time.

  Further, when the sleep control is started, the sound control means 15 continuously reduces the sound volume of the sound generation means 16 from an arbitrary sound volume at the time of sleep to about 0 decibels over a “sound sleep standby time”. That is, the sound generated by the sound generating means 16 fades out over the sound sleep time from the sleep time.

The sound sleep standby time is the time from the sleep time until the sound disappears, and is about 15 minutes.
In order to prevent the sound from disappearing even after the light generating means 14 is turned off, the time from the sleep time until the sound disappears (sound sleep sleep standby time) is the time from sleep sleep time to light extinction (light sleep sleep standby time). ) Longer than This is to adjust to sleep because the sense of vision is duller than that of hearing when falling asleep.
However, since the time required to fall asleep differs depending on the sleeper, the sound sleep sleep preliminary time can be set appropriately between 10 and 30 minutes.

As described above, the sleep environment when the sleeping person is asleep can be adjusted by light, sound, and temperature elements by the sleep control by the light control means 13, the sound control means 15, and the temperature control means 17.
Note that the temperature in the space (1.5th-order sleep environment) defined by the curtain 27 is kept substantially constant from the end of sleep control until the next wake-up control.
After the light is turned off, a dark state with almost no light is maintained in principle, but a foot lamp 33 is provided on the bed frame 24 of the bed 20 for walking when waking up at night as shown in FIG. Thus, the foot lamp 33 can be turned on. The foot lamp 33 is preferably an LED and includes an illuminance sensor so as to be turned on / off upon detection of a predetermined brightness.

Next, the control of the sleep environment adjustment system 10 when getting up will be described.
As shown in FIG. 5 and FIG. 7, when the time measuring means 12 detects that the “temperature wake-up preparation time” before the set wake-up time is detected (S 40), the control means 11 is controlled by the temperature control means 17. The wake-up control is started (S41).

  When the wake-up control is started, the temperature control unit 17 generates cold air or warm air from the air conditioning unit 18, and changes the temperature in the space (1.5th-order sleep environment) defined by the curtain 27 from the standard set temperature. The temperature is continuously increased by about 3 ° C. from the temperature lower by about 3 ° C. over the temperature wake-up preparation time up to the wake-up time. As a result, the temperature of the space defined by the curtain 27 at the sleep time becomes the standard set temperature.

The temperature wake-up preparation time is a time for shifting from a sleeping temperature to a standard set temperature, and is about 4 hours.
Setting the start time of the wake-up control by the temperature control means 17 to be about 4 hours before the wake-up time requires about 4 hours to adjust the body temperature of the sleeping person to a state suitable for the activity, If it is too short, the body temperature adjustment of the sleeper cannot respond to the temperature change of the environment, and if it is too long, the sleeper's body starts to wake up too early and the sleep time set by the sleeper is set. Because they will wake up soon.
However, since the time required for waking up preparations differs slightly depending on the individual sleepers, it is possible to set an appropriate time for a sleeper of 2 to 5 hours as the temperature waking up preparation time.

  Subsequently, when it is detected by the timing means 12 that the “sound wake-up preparation time” before the set wake-up time is detected (S42), the control means 11 starts the wake-up control of the light control means 13 ( S43).

  When the wake-up control is started, the light control unit 13 turns on the illuminating device 14 </ b> B that generates the daylight white light in the image of the morning or noon light in the light generation unit 14. Then, the illuminance is continuously increased to “wake-up illuminance” over a light wake-up preparation time until the wake-up time.

The rising illuminance is about 1000 lux on the sleeping person's face.
The purpose is to awaken the sleeper's body at once and to adjust the biological rhythm by exposing them to bright light when waking up. Further, by receiving bright light, it is possible to wake up naturally even if the volume of sound stimulation by the sound generating means 16 is not as high as that of a commercially available alarm clock.

  In addition, as shown in FIG. 4, the lighting 32 is provided on the side surface of the falling ceiling 21 so as to light up in accordance with the rising time, or the curtain 31 provided in the bedroom is electrically operated as shown in FIG. In addition, the curtain 31 can be automatically pulled and interlocked so that not only the sleeper's 1.5th-order sleep environment but also the secondary sleep environment is brightened according to the wake-up time.

The light wake-up preparation time is the time from when the light generating means 14 is lit until the wake-up time, and is about 2 hours.
In order to immerse the sleeper's body gradually in light and encourage them to get ready to wake up, the illuminance is changed from a small amount of light until the light is bright enough to adjust the biological rhythm. When the sleeping person is illuminated, the sleeping person senses a sudden change in the amount of light through the heel and wakes up when the body is not ready to wake up. Therefore, it is necessary to gradually increase the illuminance over a period of about two hours in order to give the sleeper a stimulus by light and prepare for sufficient wake-up to promote natural awakening. It is. In addition, in relation to the temperature wake-up preparation time of about 4 hours, it is preferable to apply light stimulation in a state where the body temperature adjustment for the sleeper's wake-up is advanced, and the light wake-up preparation time is about 2 hours. It is suitable to do.
However, in consideration of the sleeping time of the sleeping person, etc., an appropriate time can be set for the sleeping person of 1 to 3 hours as the photowake-up preparation time.

  When the time measuring means 12 detects that the “sound wake-up preparation time” before the set wake-up time is reached (S44), the control means 11 starts the wake-up control of the sound control means 15 (S45). ).

  When the wake-up control is started, the sound control means 15 continuously increases the sound volume of the sound generation means 16 from zero to the wake-up setting sound volume over the sound wake-up preparation time. That is, the sound generated by the sound generating means 16 fades in from the sound wake-up preparation time at the wake-up time and becomes the wake-up setting volume at the wake-up time.

The sound wake-up preparation time is the time from when the sound generator 16 starts generating sound until the wake-up time, and is about 2 hours.
Before getting up, a small sound is generated by the sound generation means 16, and this volume is gradually increased to prompt the bedridden to get ready to wake up. Instead, it takes about 2 hours to wake up with a sense of waking up more naturally. In addition, in relation to the temperature wake-up preparation time of about 4 hours, it is preferable to apply sound stimulation in a state where the body temperature adjustment for the sleeper's wake-up is present, and the sound wake-up preparation time is about 2 hours. It is suitable to do. Furthermore, in relation to the photowake-up preparation time of about 2 hours, since the auditory wakes up earlier than the visual sense, it is preferable that the sound stimulus is given somewhat earlier than the light stimulus or at the same time. Is about 2 hours.
However, considering the sleeping time of the sleeping person, an appropriate time can be set for the sleeping person of 1 to 3 hours as the sound wake-up preparation time.

  As described above, the sleep environment when the sleeping person wakes up can be adjusted by the light, sound, and temperature elements by the wake-up control by the light control means 13, the sound control means 15, and the temperature control means 17.

  In FIG. 8, on the premise that sleep environment adjustment control (sleeping control and wake-up control) of the light generation means 14 by the light control means 13 is performed, depending on the presence or absence of the sleep environment adjustment control of the air conditioning means 18 by the temperature control means 17. The effect contrast is shown.

When the sleep environment adjustment control of light and temperature is performed, the time related to the decrease in the body temperature of the sleeper at the time of sleep is shorter and the sleeper is earlier than the case where the sleep environment adjustment control of light only is performed. It turns out that the body becomes sleepy.
In addition, when the sleep environment adjustment control of light and temperature is performed, the time required for the body temperature of the sleeper to rise when waking up is shorter and faster than when the sleep environment adjustment control of light alone is performed. It can be seen that the sleeper's body awakens.

  Furthermore, when the sleep environment adjustment control of light and temperature is performed, the amount of melatonin, which is a sleep hormone, is increased in the nighttime compared with the case where the sleep environment adjustment control of light alone is performed, and the sleeper is deeper. You can see that you are asleep. For this reason, the intensity of sleepiness after getting up is less when the sleep environment adjustment control of light and temperature is performed than when the sleep environment adjustment control of light only is performed .

On the other hand, FIG. 9 shows the effect of the sleep environment adjustment control (sleeping control and waking up control) of the sound generation means 16 by the sound control means 15.
It can be seen that when sound sleep environment adjustment control is performed, the heart rate decreases, the number of sympathetic nerve indices during sleep onset is small, and the number of parasympathetic nerve indices when waking up is small compared to when the sound sleep environment adjustment control is not performed. That is, when the sleep environment adjustment control of sound is performed, compared to the case where it is not performed, there is a tendency to be more relaxed when falling asleep and to become more active when getting up.

  From the above, as shown in FIG. 10, by performing sleep environment adjustment control of light, sound, and temperature in the sleep environment adjustment system 10, a synergistic effect is obtained, and the sleeping person at the time of falling asleep and when waking up is obtained. The body temperature can be changed quickly and the sleeper's body can be quickly put to sleep / wake. You can fall asleep and get up in an active mood. That is, the sleeping person can obtain a good quality of sleep overall.
