Description

  The present invention relates to an environment control system for a toilet space.

  In recent years, there has been an increasing movement to promote remote work, such as working from home, in pursuit of workability. On the other hand, there is a concern that remote work will always be performed, which reduces opportunities to communicate with the face, and as a result, productivity will decrease. For this reason, at present, there is a demand for higher productivity in offices in order to pursue workability and to prevent productivity from lowering.

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

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

On the other hand, once you are in a relaxed state, you can concentrate on your work again. However, there is a known problem that productivity is reduced.
To cope with this problem, Patent Document 1 discloses that a stimulus for activating a living body is provided immediately after a stimulus for soothing the living body is provided, so that a person once in a relaxed state concentrates on work again. It is described that the time required until a person can be in a wakeful state can be shortened.

Hagiwara Kei, Araki Kazunori, Michimori Akihiro, "Short-Term Refresh Method and Its Physiological Evaluation", [online], published on June 1, 1991, Ergonomics Vol. 27, Special Issue, [August 28, 2018] 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 relaxation stimulating device that includes a relaxation inducing device that guides the user to relax the tension and a refresh stimulating device that provides the user with an appropriate stimulus to increase the level of consciousness. Introducing a private room space was not feasible due to space constraints and costs. Therefore, the present inventors have conceived of using the toilet space originally having a private room space and performing the control described in Patent Document 1 to lower the hurdle of introduction in terms of space and cost.

  However, according to Non-Patent Document 1 published at the same time by the same developer as Patent Document 1, a person who has once been in a relaxed state must be able to concentrate and work again before becoming awake. Even if the time is shortened by the control described in Patent Document 1, it still requires 10 to 20 minutes. Therefore, if the control described in Patent Document 1 is applied to the toilet space as it is, the occupation period of the toilet space per person becomes too long, and the toilet space is originally used by the person who wants to excrete the toilet space. A new problem has arisen that hinders use.

  The present invention is intended to solve such a problem, and is intended to be used once in a toilet space so as not to hinder the use of the toilet space by a person who wants to excrete the original purpose of the toilet space. It is an object of the present invention to provide a toilet space environment control system capable of shortening a period required until a person in a relaxed state returns to an awake state in which the person can concentrate and work again.

  In order to solve the above problems, an environment control system for a toilet space according to an aspect of the first invention is an environment control system for a toilet space installed in a building provided with an office or a public facility, The toilet space is a private room space with a toilet, a shared space with a wash basin, a first lighting device installed in the private room space and capable of changing the illuminance or color temperature in the private room space, A control device for controlling the first lighting device; a control device for controlling the first lighting device, wherein the control device includes a lighting relaxation control for reducing illuminance or a color temperature in the private room space; Controls the illuminance or color temperature in the private room space to be lower than the illuminance or color temperature in the shared space where the second lighting device is installed.

  When the invention described in Patent Literature 1 is applied to a toilet space, there is a problem that the use of a person who wants to excrete, which is the original purpose of the toilet space, is hindered. One of the reasons is that the entire period from the application of a visual stimulus to bring the user to a relaxed state to the application of the visual stimulus to bring the user to an awake state is performed in a private room with a toilet. It is mentioned.

  Therefore, the present inventors can reduce the occupation time of the private room space by giving a visual stimulus to make the user awake even in a shared space having a washstand that is a place outside the private room space. I came up with that.

  According to the first aspect of the present invention, in the lighting relaxation control, the control device reduces the illuminance or color temperature of the first illuminating device installed in the private room space, thereby reducing the illuminance or color in the private room space. The temperature is controlled to be lower than the illuminance or color temperature of the shared space where the second lighting device is installed. For this reason, the user who has entered the shared space after the lighting relaxation control receives a stronger visual stimulus than the lighting relaxation control due to the illuminance or color temperature of the shared space by the second lighting device, and activates the living body in the shared space. Will be able to This makes it possible to perform a part of the period in which the visual stimulus for bringing the user into an awake state is provided outside the private room space, and to control the toilet space environment that can reduce the occupation time of the private room space by the user. A system can be provided.

  Note that the illuminance or color temperature of the private room space or the shared space described in the present invention, the illuminance meter is disposed on the floor surface existing vertically below the first lighting device and the second lighting device, The measurement is performed by directing the light receiving unit of the illuminometer to the first lighting device or the second lighting device.

  In the toilet space environment control system according to an aspect of the second invention, in the first invention, in the first invention, the second lighting device is a passage space lighting device installed on a passage from an entrance of the toilet space to the private room space. And a wash basin space lighting device installed near the wash basin. The aisle space lighting device has an illuminance or a color temperature on a passage where the aisle space lighting device is installed, and a wash basin space lighting device. It is installed so that it is lower than the illuminance or color temperature near the wash basin, and the lighting relaxation control is to control the illuminance or color temperature in the private room space from the illuminance or color temperature on the aisle where the aisle space lighting device is installed. Is also controlled to be low.

  It is a common behavior that a user who uses the private room space leaves the private room space, moves along a passage in the shared space, wash his / her hands in the washstand, and then leaves the toilet space. The present inventors pay attention to the general behavior of the user after using the private room space, and gradually increase the strong visual sense in accordance with the movement of the user in the toilet space after performing the lighting relaxation control. I came up with the idea of stimulating the living body to make it awake. In other words, after giving the user after leaving the private room space visual stimulus by the passage space lighting device installed on the passage from the entrance of the toilet space to the private room space, it was installed near the wash basin. By giving a strong visual stimulus to the wash basin space lighting device, the user can be made awake.

  According to the second aspect of the present invention, the passage space lighting is installed on the passage from the entrance of the toilet space to the private room space, and has a higher illuminance or color temperature near the wash basin than the passage space lighting device. Wash basin lighting system was installed. Then, in the lighting relaxation control, the control device reduces the illuminance or color temperature of the first lighting device to thereby increase the illuminance or color temperature in the private room space on the passage from the entrance of the toilet space to the private room space. Illuminance or color temperature. Therefore, the user who comes out on the passage in the shared space outside the private room after the light relaxation control receives a stronger visual stimulus than the light relaxation control by the passage space lighting device, and thereafter, when washing his / her hands in the sink. In addition, the wash basin space lighting device receives a stronger visual stimulus than the passage space lighting device, and the living body can be strongly activated in the shared space. As a result, much of the period during which the visual stimulus for making the user awake can be given outside the private room space, and the environment control of the toilet space which can further reduce the occupation time of the private room space by the user. A system can be provided.

  In the present invention, the passage from the entrance of the toilet space to the private room space is a shared space from the entrance of the toilet space to the private room space. Therefore, even when the user does not use the washroom space in which the washroom space lighting device is installed, the user can use the washroom space lighting device installed in the passage from the private room space to the entrance of the toilet space. A visual stimulus for making the person awake can be reliably provided.

  In the toilet space environment control system according to an aspect of the third invention, in the second invention, the toilet space includes a plurality of private room spaces, a plurality of passage space lighting devices are provided, and each of the passage space lighting devices is It is installed near the entrance of each of a plurality of private room spaces.

  According to the third aspect of the present invention, in the toilet space provided with a plurality of private room spaces, the passage space lighting device is installed near the entrance of each private room space. Therefore, no matter which private room space the user uses, a part of the period in which the visual stimulus for bringing the user into an awake state can be reliably performed outside the private room space. Thus, it is possible to provide an environment control system for a toilet space that can reduce the occupation time of a private room space by a user.

  The toilet space environment control system according to an aspect of the fourth invention is the toilet space environment control system according to any one of the first to third inventions, wherein the toilet space includes a congestion detection device that detects a congestion state in the toilet space, Reduces the execution period of the control executed by the control device based on the detection result of the congestion detection device.

  According to the fourth aspect of the present invention, when the congestion detection device detects that the toilet space is crowded, the control device shortens the execution period of each control for guiding the user to the relaxed state. And execution of each control can be prohibited (= the execution period of the control is reduced to zero). Thus, it is possible to provide an environment control system for a toilet space that can prevent a user who wants to perform excretion, which is the original purpose of the toilet space, from hindering use of the private room space.

  The environment control system for a toilet space according to an aspect of the fifth invention is provided in any one of the first to fourth inventions, which is provided inside or outside the private room space, and controls each control for relaxing the user. There is a notification device for notifying the user of the toilet space of the execution state.

  According to the fifth aspect of the present invention, in the case where the control for putting the user in the private room space into the relaxed state is performed, the user inside the private room space is controlled until the end of the control. The remaining time can be notified. Alternatively, it is possible to notify the user waiting for the use of the private room space outside the private room space that the user in the private room space is performing the control and the remaining time until the end of the control. As a result, it is possible to reduce the waiting time, to guide the user to another private room, and to remove the trouble for the user who wants to excrete, which is the original purpose of use.

  ADVANTAGE OF THE INVENTION According to this invention, the period which gives the visual stimulus for making a user awake state so that it may not interfere with the use of the private room space by the user who wants to excrete which is the original use purpose of the toilet space It is an object of the present invention to provide an environment control system for a toilet space that can be partially performed outside a private room space and that can reduce the occupation time of the private room space by a user.

FIG. 1 is a block diagram schematically showing a toilet space environment control system according to an embodiment of the present invention.
As illustrated in FIG. 1, the toilet space environment control system 100 includes a first lighting device 200, a second lighting device 220, and a control device 400. Further, it is preferable to include the video output device 300, the congestion detection device 500, and the notification device 600.

  The first lighting device 200 is installed in a private room space provided with a toilet in a toilet space, and is a lighting device capable of changing illuminance or color temperature in the private room space. For this purpose, the first lighting device 200 includes, for example, a lighting device such as a single LED capable of dimming to different illuminances or color temperatures or a plurality of LEDs having different illuminances or color temperatures. The lighting device 200 is not limited to a light bulb-shaped lighting device provided above the private room space, but may be a panel-shaped lighting device provided on a wall surface of the private room space. Note that the lighting device 200 may be singly arranged in the private room space, but a visual effect can be obtained by installing a plurality of the lighting devices.

  The second lighting device 220 is lighting installed in a shared space provided with a wash basin in the toilet space. The second lighting device 220 includes a passage space lighting device 222 installed on the passage from the entrance of the toilet space to the private room space, and a washstand space lighting device 224 installed near the washstand. . To this end, the second lighting device 220 includes a lighting device such as an LED having a single illuminance or color temperature. The second lighting device 220 may be a lighting device capable of changing the illuminance or the color temperature similarly to the first lighting device 200.

  The video output device 300 is a device that is installed in a private room space provided with a toilet in a toilet space and outputs a still image or a moving image. For this purpose, the image output device 300 includes, for example, a display device such as an LCD (liquid crystal display) or an OLED (organic EL display) mounted on a wall surface in the private room space, a projector that projects an image into the private room space, and the like. . 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, but a larger size that spreads over the entire field of view of the user can provide a more visual effect. Note that the video output device 300 may output sound related to the video to be output together with the video.

  The control device 400 is a device that controls the illuminance or color temperature of the first lighting device 200. Further, it is preferable that the control device 400 can also control the output of a still image or a moving image output from the image output device 300. Control device 400 transmits a control instruction to first lighting device 200 and video output device 300 based on an automatic operation or a manual operation. For this purpose, for example, the control device 400 includes a memory in which control instructions are stored in advance for automatic operation, an input button for manual operation by a user, and a control instruction for the first lighting device 200 and the image output. A transmission unit for transmitting a control instruction to the device 300 is provided.

  The congestion detection device 500 is a device that detects a congestion state in the toilet space. The congestion detection device 500 detects the presence or absence of a user in a shared space provided with a wash basin or the like outside the private room space, the presence or absence of a user in another private room space, and the like. 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 reduced according to the congestion status 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 executes each control. Can be prohibited (= the execution period of the control is reduced to zero). Thus, it is possible to prevent the user who wants to perform excretion, which is the intended use of the toilet space, from hindering use of the private room space. For this purpose, as the congestion detection device 500, for example, a camera, a door sensor, a human body detection sensor, a seating detection sensor, or the like can be used.

As the door sensor, for example, detection means such as a magnet sensor, a displacement sensor, and a vibration sensor can be used for a door in a private room space. Thereby, the open / closed state of the door in another private room space is detected, and the congestion state 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. Thus, it is possible to detect the presence or absence of a user staying near the entrance of the private room space, and to detect the congestion state from the presence or absence of a user who wants to use the private room space.
Further, as the seating detection sensor, for example, detection means such as a strain sensor, a pressure sensor, and an infrared sensor can be used. Thereby, the user's sitting state in another private room space is detected, and the congestion state can be estimated from the presence or absence of the user.

  The notifying device 600 notifies the person in the private room space of the remaining time of the control time when each control for guiding the user to the relaxed state is performed, or the shared space outside the private room space has It informs the person waiting for use of 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 an illumination device such as an LED that can change the color, arrangement, and blinking cycle of light can be used. It is installed on a wall in a private room space or a common space. When the control is executed, the control device 400 transmits information on the control to the notification device 600, and the notification device 600 displays the information. The notification device 600 includes, for example, whether or not the control is executed, the remaining time until the end of the control, and the like.

  FIG. 2 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 of the present invention. Hereinafter, the control executed by the control device of the present invention will be described with reference to FIG.

  The control device 400 has a relaxation control 420 for the purpose of reducing the fatigue of the user. The relaxation control 420 includes a lighting relaxation control 422 by the first lighting device 200. It is preferable that the relaxation control 420 includes a video relaxation control 424 by the video output device 300 and a composite relaxation control 426 that overlaps the periods in which the illumination relaxation control 422 and the video relaxation control 424 are executed.

  The lighting relaxation control 422 changes the illuminance of the first lighting device 200 to a low illuminance or changes the color temperature to a low color temperature such as a warm color system to provide visual stimulation to a user in the private room space. Is a control for reducing As a result, the human mental state is guided to the relaxed side where the parasympathetic nerve is dominant, and the living body is calmed down.

  The video relaxation control 424 displays an image (first image) in which the amount of appearance of the alpha wave is small and the attenuation of the alpha wave does not appear remarkably when the alpha wave attenuation test (Alpha Attenuation Test: AAT) is performed. This is control for causing the output device 300 to output. Thereby, the mental state of the person is shifted to the relaxed side where the parasympathetic nerve is dominant.

  The alpha wave attenuation test is based on the characteristic that the amount of appearance of alpha waves when the eyes are closed and the attenuation of the alpha waves when the eyes are open fluctuates in accordance with the activity of the living body. This is an evaluation method for numerically expressing the activity of a living body from the amount of appearance of alpha waves generated by repetition and the attenuation of alpha waves.

  As a result of performing this test, an image suitable as an image to be output in the image relaxation control 424 is, for example, a color image having a low color temperature and little or no motion, such as a natural forest image, due to a visual stimulus. It was a video with few or no emotions and a psychophysiological reaction that led the body to the relaxed side by reminding the average person of peace and calm.

  The composite relaxation control 426 is a control in which the periods during which the illumination relaxation control 422 and the video relaxation control 424 are executed are overlapped. Thereby, a plurality of different visual stimuli by the first lighting device 200 and the video output device 300 work together, and a synergistic effect can be obtained. Therefore, by executing the composite relaxation control 426, the living body of the user can be calmed down in a shorter period of time than when only the illumination relaxation control 422 or the video relaxation control 424 is executed.

  FIG. 3 is a flowchart illustrating an example of the relaxation control executed by the control device in the toilet space environment control system according to the embodiment of the present invention. Hereinafter, the flow of the relaxing control in the toilet space environment control system according to the embodiment of the present invention will be described with reference to FIG.

  In step S301, it is detected that the user has entered the private room space or that the user is seated on the toilet seating portion in the private room space. When it is detected that a user is present in the private room space, the process proceeds to the next step S302. The presence or absence of entry into the private room space can be detected by a door sensor or a human body detection sensor. In addition, whether or not the toilet is seated on the seating portion can be detected by a seating detection sensor.

  In step S302, when the congestion state outside the private room space is detected by the congestion detection device 500 (step S302, Yes), the control device 400 prohibits execution of the relaxation control 420 for guiding the user to the relaxed state. . At this time, the notification device 600 may be used to notify the user in the private room space that the outside of the private room space is congested.

  On the other hand, if the congestion detection device 500 does not detect the congestion state outside the private room space in step S302 (No in step S302), the process proceeds to the next step S303, and the control device 400 relaxes the user. Allows the user to select the relax control 420 to lead to the state. Note that the selection of the relaxation control 420 in step S303 may be a manual operation performed based on an input by the user, or may be an automatic operation performed based on a seating detection or the like. Alternatively, it may be automatically determined whether or not to execute according to a predetermined condition such as a time zone.

  The control device 400 transmits information on the relaxation control 420 selected in step S303, and the notification device 600 notifies the information on the selected relaxation control 420 to the inside of the private room space and the outside of the private room space (step S304).

Then, the control device 400 starts executing the relaxation control 420 selected in step S303 (steps S305 to S311).
Note that the control flow of the illumination relaxation control 422 and the video relaxation control 424 executed by the control device 420 controlling the lighting device 200 and the video output device 300 in the relaxation control 420 will be described later with reference to FIG.

  When the congestion detection device 500 detects a congestion state outside the private room space during the execution of the relaxation control 420 (Step S306, Yes), the control device 400 controls to shorten the execution period of the relaxation control 420 (Step S306). Step S307).

  In addition, when the input operation of the stop button by the user is detected during the execution of the relax control 420 (step S308, Yes), the control device 400 forcibly terminates the execution of the relax control 420 (step S311).

  In addition, when the user has been away from the seating portion for a predetermined period of time during the execution of the relax control 420 (step S309, Yes), the control device 400 forcibly terminates the execution of the relax control 420 (step S311). In the detection of the seating portion by the user using the seating detection sensor, the user may be detected as being away from the seat for about one second due to a change in posture. Therefore, the predetermined time is preferably set to, for example, a time of about 5 seconds.

  If the predetermined time has not elapsed since the execution of the relaxation control 420 (step S310, No), the control device 400 continues to execute the relaxation control 420.

Then, when a predetermined time has elapsed since the execution of the relaxation control 420 (Step S310, Yes), the control device 400 terminates the execution of the relaxation control 420 (Step S311), and at the same time, in the private room space by the notification device 600, and The notification to the outside of the private room space ends. (Step S312).
Although not shown in FIG. 3, when the relaxation control 420 is forcibly terminated by the user's operation of the stop button or a malfunction, the process returns to step S303 so that the relaxation control 420 can be selected again. May be set. In this case, when the relaxation control 420 is selected again, the notification to the inside of the private room or the outside of the private room is executed again (step S304).

  Finally, when the exit from the private room space by the user is detected, the control by the control device 400 associated with one use of the private room space by the user ends (step S313).

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

  When execution of the relaxation control 420 is selected by an input operation or an automatic operation, the control device 400 transmits a control instruction corresponding to the relaxation control 420 to the first lighting device 200 and executes the lighting relaxation control 422. (Step S402).

  When the illuminance or color temperature in the private room space changed by the first lighting device 200 reaches a predetermined illuminance or color temperature predetermined in the selected control (step S403, Yes), the control device The 400 transmits a control instruction corresponding to the relaxation control 420 to the video output device 300, and executes the video relaxation control 424 (step S404).

  After that, the control device 400 executes the composite relaxation control 426 by the first lighting device 200 and the video output device 300, which overlaps the period for performing the illumination relaxation control 422 and the video relaxation control 424 for a predetermined period. (Step S405).

  Then, when a predetermined time has elapsed since the execution of the composite relaxation control 426 (Step S405, Yes), the control device 400 transmits a stop instruction to the video output device 300, and stops the video relaxation control 422 (Step S406). .

  Further, control device 400 also transmits a stop instruction to first lighting device 200, and stops lighting relaxation control 422 (step S407). Thereby, control device 400 ends relax control 420 (step S408).

  FIG. 5 is a diagram illustrating an example of a time chart of the relaxation control executed by the control device in the toilet space environment control system according to the embodiment of the present invention. Hereinafter, a time chart of the relaxation control in the toilet space control system according to the embodiment of the present invention will be described with reference to FIG.

When the entrance to the toilet space by the user is detected, or when the user performs an input operation to turn on the illumination of the toilet space from OFF to ON, the first lighting device 200 provided in the private room space, and The passage space lighting device 222 provided in the common space is turned on at normal illuminance and color temperature (t ₀ ). At this time, the illuminance and the color temperature in the normal state are, for example, 160 Lx (lux) and the color temperature 4000 K (Kelvin).

Next, when the execution of the relaxation control 420 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 to reduce the illuminance or the color temperature in the private room space. The execution of the illumination relaxation control 422 to be started is started (t ₁ ). In the lighting relaxation control 422, the control device 400 determines that the illuminance or color temperature in the private room space is lower than the illuminance or color temperature in a normal state before executing the relaxation control 420, and the shared space by the passage space lighting device 222. The first lighting device 200 is controlled so as to be lower than the illuminance or the color temperature. At this time, the illuminance and color temperature in the private room space reduced by the first lighting device 200 are, for example, 60 Lx and a color temperature of 2700 K.

Then, when the execution period of the illumination relaxation control 422 has passed a predetermined period that is programmed in advance, or the illuminance or color temperature in the private room space reduced by the illumination relaxation control 422 has reached the illuminance or color temperature that has been programmed in advance. At this time, the control device 400 controls the video output device 300 to perform a video relaxation control 424 that outputs a video having a low color temperature such as a warm color system or a video having an effect of causing a psychophysiological reaction such as peace or calm to a person. Start (t ₂ ). At this time, the video output by the video output device 300 is, for example, a video of a forest.

Thereafter, the control unit 400 in advance for a programmed predetermined time period, to perform a complex relaxing control 426 performed by overlapping the period for executing the lighting relaxing control 422 and image relax control 424 _(t 2 _~t 3). During this period, a plurality of different visual stimuli by the first lighting device 200 and the video output device 300 work together, so that a synergistic effect can be obtained. Therefore, the living body of the user can be calmed down more effectively than during the period in which only the lighting relaxation control 422 or the video relaxation control 424 is executed. At this time, the composite relaxation control 426 is executed, for example, for 5 minutes.

Immediately after the execution of the lighting relaxation control 422 (t _{1 to} t ₂ ), since the control device 400 is changing the illuminance or the color temperature of the first lighting device 200, it is in the private room space. Visual stimuli are not kept constant. At this time, even if the video output device 300 is controlled and the execution of the video relaxation control 424 is started, the user is aware that the illuminance or the color temperature in the private room space has been changed by the first lighting device 200. It may not be possible to obtain a synergistic effect by illumination and video. Therefore, the composite relaxation control 426 is preferably executed during a period (t _{2 to} t ₃ ) in which the illuminance of the first lighting device 200 or the color temperature is kept constant.

Then, after a lapse of a predetermined period programmed in advance, the control device 400 transmits an instruction to stop each control to the first lighting device 200 and the video output device 300 (t ₃ ).

At this time, it is preferable to perform control for increasing than when execution of the first illuminating device illuminates the illumination relaxing control 422 200 in private space _(t 3 _{~t 4).} Thereby, the private room space becomes slightly brighter, so that the user can easily check his / her hand, and it is possible to reduce the risk of inconvenience when performing a leaving operation such as releasing a key. In addition, it is possible to realize safe exit from the room, such as preventing falling.

  Further, although not shown, the illuminance of the first lighting device 200 in the private room space may be returned to the illuminance in the private room space at normal times before the start of the lighting relaxation control 422. Thereby, for example, the arousal stimulus can be given to the user for a short period of time from leaving the room to leaving the private room space. For this reason, in addition to the long-term wakeful stimulus in the shared space, the wakeful stimulus can be given immediately after the relaxation control for a short period of time.

  FIG. 6 is a diagram illustrating a schematic configuration of the toilet space according to the first embodiment. Hereinafter, a toilet space provided with the environment control system of the present embodiment will be described with reference to FIG.

  As shown in FIG. 6, the toilet space 1 includes a private room space 5 having the toilet bowl 3 and a shared space 9 having the wash basin 7.

  In the private room space 5, a first lighting device 200 capable of changing the illuminance or the color temperature in the private room space 5 is provided.

  In the shared space 9, as the second lighting device 220, a passage space lighting device 222 installed on the passage from the entrance of the toilet space 1 to the private room space 5, and a washstand installed near the washstand 7 A space lighting device 224 is provided.

  When the user selects the relaxation control 420 in the private room space 5, the control device 400 controls the first lighting device 200 installed in the private room space 5 to reduce the illuminance or the color temperature in the private room space 5. By doing so, the living body of the user in the private room space 5 is calmed down.

  After the relaxation control 420 is completed, the user who leaves the private room space 5 receives visual stimulation by the passage space lighting device 222 installed on the passage from the entrance of the toilet space 1 to the private room space 5.

  Therefore, in the relaxation control 420, the control device 400 causes the first lighting device 200 to set the illuminance or color temperature in the private room space 5 to be lower than the illuminance or color temperature of the shared space 9 in which the passage space lighting device 222 is installed. It is preferable to execute the relaxation control 420 so as to be lower. Thus, when the user exits the private room space 5, the user receives a visual stimulus from the passage space lighting device 222, so that the living body can be activated. At this time, the illuminance and the color temperature in the private room space 5 by the first lighting device 200 when the lighting relax control 420 is performed by the control device 400 are, for example, 60 Lx and the color temperature 2700 K, and the passage space lighting device 222 The illuminance and color temperature of the shared space 9 are, for example, 160 Lx and 4000 K in color temperature.

  In addition, as shown in FIG. 6, when a plurality of private room spaces 5 are provided in the toilet space 1, the passage space lighting device 222 is preferably installed near the entrance of each private room space 5. Thus, no matter which private room space 5 is used by the user, the user receives the visual stimulus from the passage space lighting device 222, so that the living body can be activated.

  The user who has received the visual stimulus for activating the living body by the passage space lighting device 222 installed near the entrance of the private room space 5 then faces the wash basin 7 and installs the wash basin spatial light near the wash basin 7. A visual stimulus from the device 224 is received.

  Therefore, the illuminance or color temperature near the wash basin 7 where the wash basin space lighting device 224 is installed has a higher illuminance or color temperature than the illuminance or color temperature of the shared space 9 where the passage space lighting device 222 is installed. Is preferred. Thus, the user activates the living body by receiving the visual stimulus by the passage space lighting device 222 after leaving the private room space 5, and further receives the visual stimulus by the washstand space lighting device 224 after that. Can be strongly activated. At this time, the illuminance and color temperature of the shared space 9 by the passage space lighting device 222 are, for example, 160 Lx and a color temperature of 4000 K, and the illuminance and color temperature of the shared space 9 by the washstand space lighting device 224 are, for example, 400 Lx and The color temperature is 4800K.
