Description

  The disclosed embodiments relate to a toilet space environment control system.

  In recent years, in order to pursue workability, there has been an increasing movement to promote remote work, including work from home. On the other hand, it is feared that there will be less opportunities for face-to-face communication due to constant remote work, and as a result, productivity will decline. Therefore, at the present time, in addition to pursuing workability, it is required to improve productivity in the office more than ever so as not to reduce productivity.

  By the way, in order to improve productivity in the office, the living body is activated and the awake state where the work can be concentrated and the relaxed state where the living body is calmed down and the feeling of fatigue can be recovered It is known that it is effective to properly switch the state. Therefore, conventionally, the lighting of the office room uses high-illumination lighting that has the effect of activating the living body, and the lighting of the rest room uses low-illumination lighting that has the effect of calming the living body. It was recommended in the 2010 JIS illumination standard.

  On the other hand, improvement of workability by calming and activating the living body is not limited to offices, but is highly necessary not only in offices but also in public facilities such as service areas of expressways. For example, a driver of a car in the service area needs a rest, but when resuming driving, concentration is required.

On the other hand, once you are in a relaxed state, you need to spend some time until you become awake so that you can concentrate on your work again. Therefore, there is a known problem that productivity decreases.
In order to solve this problem, in Patent Document 1, by giving a stimulus that activates the living body immediately after giving a stimulus that calms the living body, it is possible to refocus the person who is once in a relaxed state to perform work. It is described that the period required for getting into a wakeful state is shortened.

Kei Hagiwara, Kazunori Araki, Akihiro Michimori, "Short-term refresh method and its physiological evaluation", [online], published June 1, 1991, special issue on ergonomics Vol. 27, [August 28, 2018] Date Search], Internet <URL: https://www.jstage.jst.go.jp/article/jje1965/27/Supplement/27_Supplement_206/_article>

  However, as described in Patent Document 1, a special feature is provided that includes a relaxation guidance device that guides the user to relieve tension and a refresh stimulator that provides the user with an appropriate stimulus to raise the level of consciousness. Introducing a private room was not feasible in terms of space restrictions and costs. Therefore, the present inventors have come up with the idea that the toilet space originally provided with a private room space is used and the control described in Patent Document 1 is performed to reduce the hurdle of introduction in terms of space and cost.

  However, according to Non-Patent Document 1 announced at the same time by the same developer as that of Patent Document 1, by the time the person is once in a relaxed state, he / she can be refocused and put into an awake state in which work can be performed. Even if it was shortened by the control described in Patent Document 1, it took 10 to 20 minutes. Therefore, if the control described in Patent Document 1 is directly applied to the toilet space, the occupancy period of the toilet space per person becomes too long, so that the toilet space of the person who wants to excrete the original purpose of the toilet space is A new problem has arisen, which hinders use.

  The disclosed embodiment solves such a problem, and the toilet space is designed so as not to hinder the use of the toilet space by a person who wants to excrete, which is the original purpose of the toilet space. An object of the present invention is to provide an environmental control system for a toilet space that can shorten the period required to guide a user to a relaxed state or the period required to guide an awakened user. ..

FIG. 15 is a top view of a private room space installed in the toilet space provided with the environment control system for the toilet space according to the embodiment.

  As shown in FIGS. 1, 2 and 15, the toilet space environment control system 100 includes a first lighting device 200 and a control device 400. Further, it is preferable to have the second lighting device 220, the video output device 300, the congestion detection device 500 (not shown), and the notification device 600 (not shown).

  The first lighting device 200 and the second lighting device 220 are installed in the private room space 5 provided with the toilet bowl 3 having the seating part 1 in the toilet space, and the illuminance or color temperature in the private room space 5 can be changed. Lighting. To this end, the first lighting device 200 and the second lighting device 220 may be, for example, a single LED capable of dimming different illuminances or color temperatures, or a plurality of LEDs having different illuminances or color temperatures. Equipped with equipment. Further, the first lighting device 200 and the second lighting device 220 are not limited to light bulb-shaped lighting devices, and may be panel-shaped or rod-shaped lighting devices. It should be noted that the first lighting device 200 and the second lighting device 220 may be installed individually in the individual room space, or may be installed in plural.

It is preferable that at least a part of the first lighting device 200 is provided on the front side of the private room space 5 with respect to the line AA which is the center of the seating portion 1. Thus, when the user sits down on the seating portion 1, it is possible to give a visual stimulus from the front to the head of the user, which is present above the center of the seating portion 1, by light. In other words, the possibility that the light is blocked by the user's head or the toilet bowl 3 before it reaches the eyes of the user is reduced, and the direct light of the first lighting device 200 does not weaken the obstacle. It becomes possible to give a visual stimulus to the user.
Note that the "direct light" used in the description of the disclosed embodiments means "the light from the light source directly hits the irradiation surface without any obstacle between the light source and the irradiation surface". is there.

  Further, the first lighting device 200 is at the center of the seating portion A-A rather than Y, which is the distance from the wall surface of the private room space 5 provided in front of the seating portion 1 to the first lighting device 200. It is preferable that the distance X from the line to the first lighting device 200 is set to be shorter. As a result, the distance from the first lighting device 200 to the user's head located above the center of the seating portion 1 in the upward direction is shortened, and the possibility that light is blocked before reaching the user's eyesight is reduced. Therefore, it is possible to surely give a visual stimulus to the user by the direct light of the first lighting device 200 that is not weakened by an obstacle. The wall surface of the private room space 5 may be a door for entering and leaving the private room space 5.

The first lighting device 200 is preferably provided at a position outside the visual field of the user sitting on the seat 1. As a result, it is possible to reduce the possibility that the user's eyes flicker due to eye strain caused by the user directly seeing the light source itself of the first lighting device 200. In addition, the visual field is generally defined as “a range that can be seen without moving the eyes”, and the visual field of the user seated on the seating portion 1 is the user who sits on the seating portion 1. Is a range that can be seen without moving the eyes when facing the private room space 5 provided in front of the user.
It is generally known that the human visual field is about 180 to 200 degrees in the left-right direction, about 60 degrees in the upward direction, and about 70 degrees in the downward direction.

  Further, the first lighting device 200 is preferably provided on the upper side of the seating portion 1. As a result, there is less risk that light will be blocked by the obstacle existing below the seated portion such as the lower limb of the user before it reaches the eyes of the user. It is possible to more reliably provide the user with a visual stimulus by direct light.

It is preferable that at least a part of the second lighting device 220 is provided on the rear side of the private room space 5 with respect to the line AA which is the center of the seating portion 1. Accordingly, when the user sits down on the seating portion 1, it is possible to give a visual stimulus to the head of the user, which is present in the upper direction of the center of the seating portion 1, from behind by light. That is, the light is blocked by the user's head or the toilet bowl 3 before reaching the user's vision, and the direct light of the second lighting device 220 hits the obstacle and is reflected. It becomes possible to positively give the user visual stimulation by weakened indirect light. Therefore, combining the light from the first lighting device 200 that causes the direct light to positively act on the user's vision and the light from the second lighting device 220 that does not positively affect the direct light on the user's vision. Thus, the illuminance or the color temperature in the private room space 5 can be finely changed.
The “indirect light” used in the description of the disclosed embodiments means “there is an obstacle such as a toilet bowl or the head of the user between the light source and the irradiation surface, and the light from the light source indirectly It is the light that strikes the illuminated surface.

  More preferably, the second lighting device 220 is preferably provided below the seat portion 1. As a result, the distance until the light reaches the eyes of the user becomes longer than that provided on the upper side of the seating portion 1, so that the direct light of the second lighting device 220 hits the wall surface or the floor surface of the private room space 5. Since the possibility is increased, it is possible to give only the visual stimulus to the user by the indirect light of the second lighting device 220 which is weakened by hitting and reflecting an obstacle.

  The image output device 300 is a device that outputs a still image or a moving image in the private room space 5 in which the toilet bowl 3 is provided in the toilet space. For this purpose, the image output device 300 is, for example, a display device such as an LCD (liquid crystal display) or an OLED (organic EL display) attached to a wall surface in the private room space 5 or a projector for projecting an image in the private room space. Prepare Although there is no limitation on the size of the display surface of the display device or the size of the image projected by the projector, a larger visual effect can be obtained by using a large size that spreads over the entire visual field of the user. The moving image output apparatus 300 may output the sound related to the output image together with the image.

  The control device 400 is a device that controls the illuminance or the color temperature of the first lighting device 200. The control device 400 is a device that controls the illuminance or the color temperature of the second lighting device 220.

To this end, the control device 400 may include, for example, a memory in which control instructions are stored in advance for automatic operation, an input button for determining control instructions in response to a user's manual operation, or a user's manual operation. And a receiving unit for receiving input information from an input dial and an input bar for determining a control instruction in accordance with the operation amount by. Then, a transmission unit for transmitting the received control instruction to the first lighting device 200, the second lighting device 220, and the video output device 300 is provided.

  The congestion detection device 500 is a device that detects a congestion situation in the toilet space. The congestion detection device 500 is a device that detects the presence or absence of a user in a shared space provided outside the private room space 5, such as a washstand, and the presence or absence of a user in another private room space 5. By using the information on the congestion status detected by the congestion detection device 500, the period required for each control executed by the control device 400 can be shortened according to the congestion condition of the toilet space.

  For example, when the congestion detection device 500 detects that the toilet space is crowded, the control device 400 shortens the execution period of each control for guiding the user to a relaxed state or an awakened state, or controls each control. Can be prohibited (= control execution period is reduced to zero). As a result, it is possible to prevent the use of the private room space 5 from being hindered by the user who wants to excrete, which is the intended purpose of the toilet space. Therefore, the congestion detection device 500 can use, for example, a camera, a door sensor, a human body detection sensor, a seating detection sensor, an electronic device that can acquire position information, or the like.

As the door sensor, for example, a detection unit such as a magnet sensor, a displacement sensor, or a vibration sensor can be used for a door in a private room. Thereby, the open / closed state of the door in the other private room space can be detected, and the congestion status can be estimated from the presence or absence of the user.
Further, as the human body detection sensor, for example, detection means such as an infrared line sensor or a microwave sensor can be used. This makes it possible to detect the presence / absence of a user staying in the vicinity of the entrance / exit of the private room space, and detect the congestion status from the presence / absence of a user who wants to use the private room space.
Further, as the seating detection sensor, for example, a detection unit such as a strain sensor, a pressure sensor, an infrared sensor can be used. Thereby, the seated state of the user in the other private room space can be detected, and the congestion status can be estimated from the presence or absence of the user.
As an electronic device that can acquire position information, for example, an electronic device equipped with a positioning sensor and a device in the toilet space can share electronic information by optical communication or wireless communication. As a result, the location of the user who owns the electronic device can be detected and the congestion status can be estimated.

  The alerting | reporting apparatus 600 alert | reports the remaining time of the said control time to the person in the private room space 5 when each control for guiding a user to a relaxed state or an awake state is performed, or sharing outside the private room space 5. This is a device for informing a person who is waiting to use the private room space 5 in a space, the execution state of the control. As the notification device 600, a display device such as an LCD (liquid crystal display device) or an OLED (organic EL display), or a lighting device such as an LED capable of changing the color and arrangement of light, a blinking cycle, and the like can be used. It is arranged on the wall surface in the private room space 5 or the common space. When the control is executed, the control device 400 transmits information related to the control to the notification device 600, and the notification device displays the information. Examples of the notification device include the presence / absence of execution of the control, the remaining time until the end of the control, and the like.

  Further, as shown in FIG. 2, in the toilet space in which a plurality of private room spaces 5 are excreted, the adjacent private room spaces 5 are partitioned by a partition part 7.

  The partition part 7 prevents the light from the first lighting device 200 and the second lighting device provided in a certain private room space 5 from affecting the illuminance and the color temperature in the adjacent private room space 5. And is formed of a light-shielding material.

  Further, it is preferable that the partition portion 7 extends to the upper end and the lower end of the private room space 5. Accordingly, even if the first lighting device 200 and the second lighting device 220 are provided above and below the seating portion 1 of the private room space 5, the illuminance and the color temperature of the adjacent private room space 5 are increased. Can be prevented. The partition 7 may be formed as a wall surface of the private room space 5.

  Further, as shown in FIG. 15, when the plurality of first lighting devices 200 are provided in the private room 5, the plurality of first lighting devices 200 are located on the left side and the right side of the center of the seating portion 1. It is preferably provided on each side. Thereby, the illuminance and the color temperature in the private room space 5 can be made more uniform, and the intended visual effect can be given to the user regardless of the user's eyes. The same applies to the second lighting device 220.

  Further, the shape of the private room space 5 is not limited to a quadrangle, and the shape is such that both sides expand like a hexagon to give the user a spacious impression and aim to enhance the effect of leading the user to a relaxed state. I don't care.

  FIG. 3 is a diagram schematically showing a conceptual diagram of control executed by the control device in the toilet space environment control system according to the embodiment. Hereinafter, with reference to FIG. 3, three control patterns executed by the control device in the disclosed embodiment will be described.

(First control pattern: relaxation control)
The first control pattern is relax control 420. The relaxation control 420 is a period for executing the illumination relaxation control 422 by the first illumination device 200 and the second illumination device 220, the image relaxation control 424 by the image output device 300, and the illumination relaxation control 422 and the image relaxation control 424. And a composite relax control 426 for overlapping.

  The relaxation control 420 is a control intended to reduce the user's fatigue, and executes the lighting relaxation control 422, the image relaxation control 424 or the composite relaxation control 426 to calm the user's living body. It becomes possible.

  The lighting relaxing control 422 changes the illuminance of the first lighting device 200 and the second lighting device 220 to a low illuminance, or changes the color temperature to a low color temperature such as a warm color system so that the interior space of the private room is reduced. The control is to reduce the illuminance or color temperature of the image and to reduce the visual stimulus. This leads the person's mental state to the relaxed side where the parasympathetic nerve is dominant, and calms the body.

  Further, in the lighting relaxation control 422, the weaker the visual stimulus to the user, the more the user can be put into a relaxed state in a short time. Therefore, the first illuminating device 200 that gives direct light with strong visual stimulus. It is preferable that the illuminance or color temperature of the second illumination device 220 is lower than the illuminance or color temperature of the second illumination device 220.

  The image relaxation control 424 is an image (first image) in which the alpha wave does not appear significantly and the attenuation of the alpha wave does not appear significantly when the alpha wave attenuation test (AAT) is performed. This is control for causing the output device 300 to output. This shifts the mental state of the person to the relaxed side where the parasympathetic nerve is dominant.

  Note that the alpha wave attenuation test uses the characteristics that the alpha wave appearance amount when the eye is resting and the attenuation of the alpha wave when the eye is open fluctuates according to the activity of the living body. This is an evaluation method in which the activity of a living body is numerically indexed from the appearance amount of alpha waves generated by repetition and the attenuation of alpha waves. For example, an image suitable for image relaxation control can be selected by performing this test after displaying an arbitrary image for a predetermined period of time to determine the activity level of the living body.

  As a result of this test, an image suitable as an image to be output by the image relaxation control 424 is, for example, an image of a natural forest, which has a low color temperature and has no motion or almost no motion, and therefore, a visual stimulus. It was a video with few feelings, and an image that evokes a psychophysiological reaction that leads the living body to the relaxed side by reminding the average person of things such as comfort and peace.

  The composite relax control 426 is a control performed by overlapping the periods in which the illumination relax control 422 and the image relax control 424 are executed. As a result, a plurality of different visual stimuli by at least the first lighting device 200 and the video output device 300 are linked, and a synergistic effect can be obtained. Therefore, by executing the combined relax control 426, it becomes possible to calm the living body of the user in a shorter period than when the illumination relax control 422 or the image relax control 424 is executed.

(Second control pattern: awakening control)
The second control pattern is awakening control 440. The awakening control 440 is a period during which the lighting awakening control 442 by the first lighting device 200 and the second lighting device 220, the video awakening control 444 by the video output device 300, the lighting awakening control 442, and the video awakening control 444 are executed. And a composite awakening control 446 for overlapping.

  The awakening control 440 is a control intended to increase the user's concentration, and activates the living body of the user by executing the lighting awakening control 442, the image awakening control 444, or the composite awakening control 446. Is possible.

  The lighting awakening control 442 changes the illuminance of the first lighting device 200 and the second lighting device 220 to a high illuminance, or changes the color temperature to a high color temperature such as a cold color system, so that the inside of the private room space is changed. This is a control for increasing the illuminance or the color temperature. As a result, the human mental state is guided to the awake side where the sympathetic nerve is dominant, and the living body is activated.

  Further, in the lighting / awakening control 442, the stronger the visual stimulus to the user, the more the user can be awakened in a short time, and thus the first lighting capable of giving direct light with high visual stimulus. The illuminance or color temperature of the device 200 is preferably higher than the illuminance or color temperature of the second lighting device 220.

  The image wakeup control 444 outputs the image (second image) in which the alpha wave appears a lot and the attenuation of the alpha wave is remarkable when the alpha wave attenuation test (AAT) is performed. This is a control for causing the device 300 to output. This shifts the mental state of the person to the awake side where the sympathetic nerve is dominant.

  As a result of this test, an image suitable as an image to be output in the image wakeup control 444 is, for example, an image with a lot of visual stimulus because it has a high color temperature and there is a motion, such as an image of the natural sea. Moreover, it was a video that induces psychophysiological reactions that lead the living body to the awake side by reminding the average person of tension and anxiety, curiosity and inquiry.

  The composite awakening control 446 is a control performed by overlapping the periods in which the illumination awakening control 442 and the video awakening control 444 are executed. As a result, a plurality of different visual stimuli by at least the first lighting device 200 and the video output device 300 are linked, and a synergistic effect can be obtained. Therefore, by executing the composite awakening control 446, it is possible to activate the living body of the user in a shorter time than when the lighting awakening control 442 or the video awakening control 444 is executed.

(Third control pattern: refresh control)
The third control pattern is refresh control 460. The refresh control 460 is a control for executing the awakening control 440 described above similarly immediately after the execution of the relaxation control 420 described above.

  FIG. 4 is a flowchart showing an example of control executed by the control device in the toilet space environment control system according to the embodiment. Hereinafter, a control flow in the toilet space environment control system according to the embodiment will be described with reference to FIG. 4.

  In step S401, it is detected whether the user enters the private room space 5 or the user sits on the seat portion 1 of the toilet bowl 3 in the private room space 5. As a result, when it is detected that the user is present in the private room space 5, the process proceeds to the next step S402. The presence / absence of entry into the private room space 5 can be detected by a door sensor or a human body detection sensor. Whether or not the toilet bowl 3 is seated on the seating portion 1 can be detected by a seating detection sensor.

  In step S402, when the congestion detection device 500 detects a congestion situation outside the private room 5 (step S402, Yes), the control device 400 executes a control mode for guiding the user to a relaxed state or an awakened state. Prohibit At this time, the notification device 600 may be used to notify the user in the private room space 5 that the outside of the private room space 5 is crowded.

  On the other hand, in step S402, when the congestion detection device 500 does not detect the congestion situation outside the private room space 5 (step S402, No), the process proceeds to the next step S403, and the control device 400 identifies the user. Allows selection of a control mode for leading to a relaxed or awake state. The selection of the control mode in step S403 may be a manual operation for executing the control input by the user or an automatic operation for executing the pre-programmed control with the seating detection or the like as a starting point. .. Alternatively, the corresponding control mode may be automatically determined according to a predetermined condition such as a time zone.

  The control device 400 transmits the information about the selected control in step S403, and the notification device notifies the inside of the private room space 5 and the outside of the private room space 5 of the information about the selected control (step S404).

  When the control selected in step S403 is the relaxation control 420, the control device 400 executes the relaxation control 420 (steps S405 to S411). Regarding the control flow of the illumination relaxation control 422 and the image relaxation control 424, which is executed by the control device 400 controlling the first illumination device 200, the second illumination device 220, and the image output device 300 in the relaxation control 420. Will be described later with reference to FIG.

  If the control selected in step S403 is the awakening control 440, the control device 400 executes the awakening control 440 (steps S412 to S418). Regarding the control flow of the lighting awakening control 442 and the video awakening control 424, which is executed by the control device 400 controlling the first lighting device 200, the second lighting device 220, and the video output device 300 in the awakening control 440. Will be described later with reference to FIG.

  When the congestion detection device 500 detects a congestion situation outside the private room space 5 during execution of the relaxation control 420 or the awakening control 440 (step S406 or step S413, Yes), the control device 400 causes the relaxation control 420 or the awakening. Control is performed so as to shorten the execution period of the control 440 (step S407 or step S414).

  Further, when the input operation to the stop button by the user is detected during the execution of the relax control 420 or the wakeup control 440 (step S408 or step S415, Yes), the control device 400 causes the relax control 420 or the wakeup control 440. Is forcibly terminated (step S411 or step S418).

  In addition, when the separation from the seating portion 1 is detected for a predetermined time during execution of the relaxation control 420 or the awakening control 440 (step S409 or step S416, Yes), the control device 400 causes the relaxation control 420 or the awakening control 440. Is forcibly terminated (step S411 or step S418). The detection of the seating portion 1 by the user using the seating detection sensor may be detected as being away from the user for a time of about 1 second due to a change in posture of the user. Therefore, it is preferable to set the predetermined time to, for example, about 5 seconds.

  When the predetermined time has not elapsed after executing the relax control 420 or the awakening control 440 (step S410 or step S417, No), the control device 400 continues to execute the relax control 420 or the awakening control 440.

  When the control selected in step S403 is the refresh control 460, the control device 400 executes the refresh control 460 (steps S419 to S424). As described above, the refresh control 460 executes the relax control 420 (steps S421 to S421), and then executes the awakening control 440 (steps S422 to S423).

Then, the control device 400 terminates the execution of the relaxation control 420, the awakening control 440, or the refresh control 460 (step S411, step S418, or step S424), and at the same time, the inside of the private room space 5 and the outside of the private room space 5 are notified by the notification device 600. The notification ends. (Step S425).
Although not shown in FIG. 4, when the control is forcibly terminated by the user operating the stop button or erroneous operation, the process may be set to return to step S403 to select the control mode again. In this case, the notification to the inside of the private room space 5 or the outside of the private room space 5 is executed according to the newly selected control (S404).

  Finally, the exit from the private room space 5 by the user is detected, so that the control by the control device 400 is completed in association with the single use of the private room space 5 by the user (step S426).

FIG. 5 is a flowchart showing an example of the relaxation control executed by the control device in the toilet space environment control system according to the embodiment.
FIG. 6 is a flowchart showing an example of awakening control executed by the control device in the toilet space environment control system according to the embodiment.
Hereinafter, the control flow of the relaxation control and the awakening control in the toilet space environment control system according to the embodiment will be described with reference to FIGS. 5 and 6.

  When it is selected to execute the relaxation control 420 or the awakening control 440 by an input operation or an automatic operation (step S501 or step S601), the control device 400 outputs a control instruction corresponding to the selected control to the first lighting. The data is transmitted to the device 200 and the second lighting device 220, and the lighting relaxation control 422 is executed (step S502 or step S602).

  Then, when the illuminance or color temperature of the first illuminating device 200 and the second illuminating device 220 reaches a predetermined illuminance or color temperature defined in advance in the selected control (step S503 or step S603, Yes). The control device 400 transmits a control instruction corresponding to the control selected in step S501 or step S601 to the video output device 300, and executes the video relaxation control 424 or the video awakening control 444 (step S504 or step S604).

  After that, the control device 400 has a period in which the lighting relaxing control 422 and the video relaxing control 424 are executed by the first lighting device 200, the second lighting device 220, and the video output device 300 for a predetermined period. The composite relaxation control 426 to be overlapped or the composite awakening control 446 to overlap the period for executing the illumination awakening control 442 and the video awakening control 444 is executed (step S505 or step S605).

  Then, when a predetermined time has elapsed after executing the composite relaxation control 426 or the composite awakening control 446 (step S505 or step S605, Yes), the control device 400 transmits a stop instruction to the video output device 300 to perform the video relaxation control. 422 or the video awakening control 442 is stopped (step S506 or step S606).

  Further, the control device 400 also transmits a stop instruction to the first lighting device 200 and the second lighting device 220, and stops the lighting relaxing control 422 or the lighting awakening control 442 (step S507 or step S607). Accordingly, the control device 400 ends the relaxation control 420 or the awakening control 440 (step S508 or step S608).

  FIG. 7, FIG. 8 and FIG. 9 are diagrams showing an example of time charts of the relaxation control, the awakening control, and the refresh control executed by the control device in the toilet space environment control system according to the embodiment. Hereinafter, the time charts of the relaxation control, the awakening control, and the refresh control in the toilet space control system according to the embodiment will be described with reference to FIGS. 7 to 9.

  First, a time chart of the relax control 420 will be described with reference to FIG.

  The first lighting device provided in the private room space 5 when the user's entry into the toilet space is automatically detected or when the user performs an input operation to turn on the illumination of the toilet space from OFF to ON. 200 is turned on with normal illuminance and color temperature (t0). The normal illuminance and color temperature at this time are 160 Lx (lux) and color temperature 4000 K (Kelvin), for example.

  Next, when starting the execution of the relaxation control 420 based on the automatic operation or the manual operation, the control device 400 controls the illuminance or the color temperature of the first lighting device 200 and the second lighting device 220, and the private room space. The illumination relaxation control 422 for lowering the illuminance or the color temperature within 5 is started (t1). At this time, the illuminance and the color temperature in the private room space 5 lowered by the first lighting device 200 and the second lighting device 220 are, for example, in the range of 60 to 160 Lx (lux) and the color temperature 2700 to 4000 K (Kelvin). Is set to fit in.

  Then, when the execution period of the lighting relaxing control 422 has passed a preprogrammed predetermined period, or the illuminance or color temperature in the private room space 5 lowered by the lighting relaxing control 422 is set based on automatic operation or manual operation. When the illuminance or the color temperature is reached, the control device 400 controls the image output device 300, and an image having a low color temperature such as a warm color system or an image having an effect of causing a psychophysiological reaction such as comfort and calmness to a person. The video relax control 424 for outputting is started (t2). At this time, the image output by the image output device 300 is, for example, a forest image.

  After that, the control device 400 executes the combined relaxation control 426, which is performed by overlapping the periods in which the lighting relaxation control 422 and the image relaxation control 424 are executed over a predetermined period programmed in advance (t2 to t3). During this period, a plurality of different visual stimuli from the first lighting device 200, the second lighting device 220, and the video output device 300 are linked, so that a synergistic effect of illumination and video can be obtained. Therefore, it becomes possible to calm the living body of the user more effectively than during the period in which the illumination relaxing control 422 or the image relaxing control 424 is executed. At this time, the composite relax control 426 is executed for 5 minutes, for example.

  Immediately after the illumination relaxing control 422 is executed (t1 to t2), it is during the period in which the control device 400 is changing the illuminance or the color temperature of the first lighting device 200 and the second lighting device 220. The visual stimulus in the private room space 5 is not kept constant. At this time, even if the image output device 300 is controlled to start execution of the image relaxation control 424, the user can adjust the illuminance or the color temperature in the private room space 5 by the first lighting device 200 and the second lighting device 220. They may be distracted by the changes, and may not be able to obtain the synergistic effect of lighting and images. Therefore, it is preferable to execute the composite relax control 426 during a period (t2 to t3) in which the illuminance or the color temperature in the private room space 5 is kept constant.

  Then, after a lapse of a preprogrammed predetermined period, the control device 400 transmits a stop instruction of each control to the first lighting device 200, the second lighting device 220, and the video output device 300 (t3). After that, when the illuminance or color temperature in the private room space 5 reaches the illuminance or color temperature in normal times, the relaxation control 420 by the control device 400 ends (t4).

  Next, a time chart of the awakening control 440 will be described with reference to FIG. Note that the control of t0 has the same control content as the relax control 420, and thus the description thereof will be omitted.

  When the execution of the awakening control 440 is started based on the automatic operation or the manual operation, the control device 400 controls the illuminance or the color temperature of the first lighting device 200 and the second lighting device 220, and the illuminance in the private room space 5. Alternatively, the execution of the illumination / wakeup control 442 for increasing the color temperature is started (t1). At this time, the illuminance and the color temperature in the private room space 5 raised by the first lighting device 200 and the second lighting device 220 are, for example, in the range of 160 to 400 Lx (lux) and the color temperature of 4000 K to 4800 K (Kelvin). Is set to fit in.

  Then, when the execution period of the lighting awakening control 442 has passed a predetermined programmed period, or the illuminance or color temperature in the private room space 5 increased by the lighting awakening control 442 is set based on automatic operation or manual operation. When the illuminance or the color temperature is reached, the control device 400 controls the image output device 300 to display an image having a high color temperature such as a cold color system, a person's tension or anxiety, or a psychophysiological factor such as curiosity or inquiry. The video alert control 444 that outputs a video having an effect of causing a reaction is started (t2). At this time, the image output by the image output device 300 is, for example, a sea image.

  After that, the control device 400 executes the composite awakening control 446, which is performed by overlapping the periods in which the illumination awakening control 442 and the video awakening control 444 are executed, over a predetermined period programmed in advance (t2 to t3). During this period, a plurality of different visual stimuli from the first lighting device 200, the second lighting device 220, and the video output device 300 are linked, so that a synergistic effect can be obtained. Therefore, the living body of the user can be more effectively activated than during the period in which the illumination / wakefulness control 442 or the video / wakefulness control 444 is being executed. At this time, the composite awakening control 446 is executed, for example, for 5 minutes.

  Since the control device 400 is changing the illuminance or the color temperature of the first lighting device 200 and the second lighting device 220 immediately after the lighting / wakening control 442 is executed (t1 to t2), it is during the period. The visual stimulus in the private room space 5 is not kept constant. At this time, even if the video output device 300 is controlled to start the execution of the video awakening control 444, the user can control the illuminance or the color temperature in the private room space 5 by the first lighting device 200 and the second lighting device 220. They may be distracted by the change, and may not be able to obtain the synergistic effect of the illumination and the image. Therefore, the composite awakening control 446 is preferably executed during a period (t2 to t3) in which the illuminance or the color temperature in the private room space 5 is kept constant.

  Then, after a lapse of a preprogrammed predetermined period, the control device 400 transmits a stop instruction of each control to the first lighting device 200, the second lighting device 220, and the video output device 300 (t3). After that, when the illuminance or color temperature in the private room space 5 reaches the illuminance or color temperature in normal times, the awakening control 440 by the control device 400 ends (t4).

  Finally, a time chart of the refresh control 460 will be described with reference to FIG. Note that the control of t0 has the same control contents as the relax control 420 and the awakening control 440, and therefore a description thereof will be omitted.

  When the execution of the refresh control 460 is started based on the automatic operation or the manual operation, the control device 400 controls the illuminance or the color temperature of the first lighting device 200 and the second lighting device 220, and the illuminance in the private room space 5. Alternatively, the execution of the illumination relaxing control 422 for lowering the color temperature is started (t1). At this time, the illuminance and the color temperature in the private room space 5 lowered by the first lighting device 200 and the second lighting device 220 are, for example, in the range of 60 to 160 Lx (lux) and the color temperature 2700 to 4000 K (Kelvin). Is set to fit in.

  In the refresh control 460, when the lighting relaxation control 422 or the lighting relaxation control 422 is executed, it is preferable not to reduce the illuminance in the private room space 5 to zero. The closer the illuminance in the private room space 5 is to zero, the more the visual stimulus is reduced, so that the effect of calming the living body can be enhanced, but on the other hand, the sleep desire of the user is enhanced. Then, even if the awakening control 440 is executed immediately after the relaxation control 420 is executed, there arises a problem that the period required until the user becomes awake so that the user can concentrate and work again cannot be shortened. This is because.

  Then, when the execution period of the lighting relaxing control 422 has passed a predetermined programmed period, or the illuminance or color temperature in the private room space 5 lowered by the lighting relaxing control 422 is set based on automatic operation or manual operation. When the illuminance or the color temperature is reached, the control device 400 controls the image output device 300, and an image having a low color temperature such as a warm color system or an image having an effect of causing a psychophysiological reaction such as comfort and calmness to a person. The video relax control 424 for outputting is started (t2). At this time, the image output by the image output device 300 is, for example, a forest image.

  After that, the control device 400 executes the combined relaxation control 426, which is performed by overlapping the periods in which the lighting relaxation control 422 and the image relaxation control 424 are executed over a predetermined period programmed in advance (t2 to t3). At this time, the composite relax control 426 is executed for, for example, 3.5 minutes.

  Then, after a lapse of a predetermined period after executing the combined relax control 426, the control device 400 transmits a stop instruction of the image relax control 424 to the image output device 300 (t3). At the same time, the control device 400 controls the illuminance or color temperature of the first illuminating device 200 and the second illuminating device 220, and starts the execution of the lighting awakening control 442 that raises the illuminance or color temperature in the private room space 5.

  In the refresh control 460, if the image awakening control 444 is executed during the execution period of the illumination relaxing control 422, the illuminance difference between the illuminance in the private room space 5 and the illuminance of the image output by the image output device 300 is reduced. The larger size may cause the user to receive too much visual stimulation. Therefore, it is preferable that the control device 400 perform control so that the image awakening control 444 is not executed during the execution period of the illumination relaxing control 422.

  Then, when the execution period of the lighting awakening control 442 has passed a predetermined programmed period, or the illuminance or color temperature in the private room space 5 increased by the lighting awakening control 442 reaches the preprogrammed illuminance or color temperature. At this time, the control device 400 controls the image output device 300 to produce an image having a high color temperature such as a cold color system, or an image having the effect of causing a psychophysiological reaction such as tension or anxiety, or curiosity or inquisitiveness to a person. The video awakening control 444 for outputting is started (t4). At this time, the illuminance and the color temperature in the private room space 5 raised by the first lighting device 200 and the second lighting device 220 are, for example, in the range of 160 to 400 Lx (lux) and the color temperature of 4000 K to 4800 K (Kelvin). Is set to fit in. The video output by the video output device 300 is, for example, a sea video.

  In addition, in the refresh control 460, when the lighting awakening control 442 is executed, the illuminance in the private room space 5 when the lighting awakening control 442 is executed is set to the normal private room space 5 before the refresh control 460 is executed. It is preferable to control the illuminance to be larger than the illuminance. In other words, it is preferable that the illuminance in the private room space 5 in normal times <the illuminance in the private room space 5 at the time of the illumination / wake-up control 442. As a result, the living body of the user who has been calmed down can be activated, and the user can be put into an awake state where the user can concentrate and work again in a short period of time.

  Furthermore, in the refresh control 460, when the lighting relaxing control 422 and the lighting awakening control 442 are executed, the illuminance and the lighting relaxing control 422 in the normal private room space 5 before executing the refresh control 460 are executed. The first illuminance difference, which is the difference between the illuminance in the private room space 5 at that time and the illuminance in the normal private room space 5 before executing the refresh control 460, and the lighting awakening control 442 It is preferable to control so that the second illuminance difference, which is the difference from the illuminance in the private room space 5, becomes larger. That is, the first illuminance difference (the illuminance in the private room 5 during normal times-the illuminance in the private room 5 at the time of lighting relaxation control 422) <the second illuminance difference (the illuminance in the private space 5 at the time of lighting awakening control 442) -Illuminance in the private room space 5 at normal times) is preferable. As a result, the living body of the user who has been calmed down can be activated, and the user can be put into an awake state where the user can concentrate and work again in a short period of time.

  After that, the control device 400 executes the composite awakening control 446 performed by overlapping the periods in which the illumination awakening control 442 and the video awakening control 444 are performed over a predetermined period programmed in advance (t4 to t5). At this time, the composite awakening control 446 is executed, for example, for 1.5 minutes.

  The execution period of the composite awakening control 446 in the refresh control 460 is the illuminance in the private room space 5 before executing the refresh control 460 and the illuminance in the private room space 5 when the lighting relaxing control 422 is executed. The first illuminance difference, which is the difference between and, is greater than the relaxation stimulus value that is the result of multiplying the period during which the lighting relaxing control 422 is being executed, and the inside of the private room 5 when the lighting relaxing control 422 is being executed. An awakening stimulus value that is the result of multiplying the third illuminance difference, which is the difference between the illuminance and the illuminance in the private room space 5 when the illumination wakeup control 442 is executed, by the period in which the illumination wakeup control 442 is executed. It is preferable to control so as to be larger. That is, it is preferable that the relaxation stimulus value (first illuminance difference × execution period of lighting relaxation control 422) <awakening stimulus value (third illuminance difference × execution period of lighting / wakening control 442). As a result, the living body of the user who has been calmed down can be activated, and the user can be put into an awake state where the user can concentrate and work again in a short period of time.

  Furthermore, in the refresh control 460, it is preferable to control the execution period of the composite awakening control 446 to be equal to or less than the execution period of the composite relaxation control 426. That is, it is preferable that the execution period of the composite relaxation control 426 ≧ the execution period of the composite awakening control 446.

  The awakening control 440, which has the effect of activating the living body, is a control that increases the visual stimulus to the user, and therefore the living body responds immediately, while the relaxation control 420 that has the effect of calming the living body is performed by the living body. React slowly. Therefore, the relaxation control value 420 needs to be relatively long so that the relaxation stimulus value is less than the awakening stimulus value after the user's living body is effectively calmed for a short time. By giving a visual stimulus to the user, the user can be put into an awake state where he / she can concentrate and work again in a short period of time.

  Then, after a lapse of a preprogrammed predetermined period, the control device 400 transmits an instruction to stop each control to the first lighting device 200, the second lighting device 220, and the video output device 300 (t5). After that, the illuminance or color temperature of the first illuminating device 200 and the second illuminating device 220 reaches the illuminance or color temperature under normal conditions, and the refresh control 460 by the control device 400 ends (t6).

As the shape of the lens, for example, a dome shape or an aspherical shape can achieve the above effects.

FIG. 13 is a conceptual diagram of a verification test site where a questionnaire is conducted regarding the visibility with respect to the height position of the video output by the video output device in the private room space in the verification test of the toilet space environment control system according to the embodiment. ..
FIG. 14 is a result of a questionnaire about the visibility with respect to the height position of the image output in the private room space by the image output device in the verification test of the environmental control system for the toilet space according to the embodiment.
Hereinafter, an appropriate position for installing the video output device will be described with reference to FIGS. 13 and 14.

  As shown in FIG. 13, the present inventors prepared a private room space 5 in which the image output device 300 is installed as an environment for the verification test, and separated about 800 mm from the tip of the toilet bowl 3 installed in the private room space 5. A monitor (width x height: 264 mm x 200 mm), which is the image output device 300, was installed on the door that is the wall surface of the private room space 5 provided in front of the toilet bowl 3. Then, while changing the height position from the floor of the private room space 5 in which the monitor is installed, a questionnaire was conducted regarding the visibility of the video output by the video output device 300 into the private room space 5.

  In this demonstration test, the center of the image that outputs the heights of 1150 mm and 1100 mm from the floor surface of the private room space 5, which is the average height of the sitting heights of the male and the female when sitting on the sitting portion 1 of the toilet bowl 3, A total of 20 males and 20 females were surveyed while changing the height position at which the image was output every 200 mm from a height of 550 mm or 500 mm to a height of 1350 mm and 1300 mm.

  In the questionnaire, "very hard to see (1)", "hard to see (2)", "somewhat difficult to see (3)", "normal (4)", "somewhat easy to see (5)", "easy to see (6)", " The subjects were asked to give their impressions regarding visibility in seven stages, which are "very easy to see (7)".

The inventors of the present invention evaluated the visibility using the standardized numerical values for the scores for each subject obtained from the questionnaire results.
To give a specific example, for example, in the case of Mr. A (male), a height of 550 mm from the floor is evaluated as "1", a height of 750 mm is evaluated as "2", and a height of 950 mm is evaluated. The evaluation was “7”, the evaluation was “2” for the height position of 1150 mm, and the evaluation was “1” for the height position of 1350 mm. The evaluation value is standardized, and the evaluation is “-0.6375” for the height position of 550 mm from the floor, the evaluation is “-0.239” for the height position of 750 mm, and the evaluation is for the height position of 950 mm. A numerical value converted such that the evaluation was “1.753”, the evaluation was “−0.239” for the height position of 1150 mm, and the evaluation was “−0.6375” for the height position of 1350 mm was used.

Then, as shown in FIG. 14, an upper approximation line and a lower approximation line are drawn with respect to the plot points obtained by averaging the numerical values obtained by standardizing the evaluation values of 10 males and 10 females. As a result, the male approximate line intersected at a position of about 950 mm from the floor surface of the private room space 5. Further, the approximate line of the woman crossed was about 1000 mm above the floor of the private room space 5.
Since the size of the monitor installed on the door, which is the wall surface of the private room space 5 in this verification test, was 200 mm in the height direction, the width of 100 mm above and below the intersection of the approximate lines of the men and women, from 850 mm to 1100 mm. It was found that the visibility is improved by outputting the image in the meantime.
