[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-111307 Summary of the Invention [Problem to be solved by the invention]

[0004] However, bathrooms that provide a relaxing effect on the mind and body, such as the bathroom mindfulness practice support system shown in Patent Document 1, have a problem in that users use the bathroom for long periods of time, making it unavailable to third parties other than the user, creating a need to ensure opportunities for third parties to use the bathroom. This problem is particularly pronounced when bathrooms are located within facilities such as offices that are used by third parties other than the user, due to recent changes in lifestyles and working styles. Furthermore, when bathrooms are located within facilities such as offices, a new problem has arisen: users need to be able to use the bathroom conveniently and freely while limiting long periods of use and providing a relaxing effect on the mind and body in a relatively short period of time.

[0005] Therefore, the present invention aims to provide a bathroom system that improves the convenience of users in using spatial presentation and prevents users from using spatial presentation for long periods of time, making it easier for users to concentrate and enjoy the relaxing effects on their mind and body in a relatively short period of time. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, one embodiment of the present invention is a bathroom system comprising a bathroom, a changing room adjacent to the bathroom, a presentation means for performing at least one of video display, audio output, and lighting control to create a spatial presentation of the bathroom, a start operation unit for starting the spatial presentation of the bathroom by the presentation means when operated by a user, and a control unit for controlling the presentation means, wherein the control unit has an automatic end mode that automatically ends the spatial presentation within a predetermined time after starting the spatial presentation of the bathroom based on an operation on the start operation unit. According to one embodiment of the present invention configured in this manner, the user can start the bathroom spatial presentation by the presentation means by operating the start operation unit, which improves convenience by allowing the user to adjust the timing of using the spatial presentation, as compared to when the spatial presentation is automatically started upon entering the bathroom, and also improves the user's freedom to decide how to use the spatial presentation, etc. Furthermore, the control unit has an automatic end mode that automatically ends the spatial presentation within a predetermined time after starting the bathroom spatial presentation based on the operation of the start operation unit, so the automatic end mode of the control unit can prevent the user from using the spatial presentation for a long period of time, making it easier for the user to concentrate and enjoy the relaxing effects of mind and body in a relatively short period of time.

[0007] In one embodiment of the present invention, preferably, the presentation means comprises a projector installed in the changing room and an image display unit that displays the image projected by the projector, the image display unit being arranged between the changing room and the bathroom and configured so that the projected image can be viewed from the bathroom, and the presentation means performs spatial presentation of the bathroom by at least executing an image display that displays the image projected by the projector on the image display unit. According to one embodiment of the present invention configured as described above, the rendering unit performs spatial rendering of the bathroom by at least executing image display that displays an image projected by the projector on the image display unit, thereby enabling the rendering unit to improve the rendering effect of the spatial rendering by performing rendering including image display.

[0008] In one embodiment of the present invention, preferably, the device further includes a door opening / closing detection sensor that detects the opening and closing of a bathroom door located between the bathroom and the changing room, the image display unit is located on the bathroom door, and the control unit has an interruption mode that interrupts the projection of images by the projector when the door opening / closing detection sensor detects the opening of the bathroom door while the spatial presentation means is performing the spatial presentation. According to one embodiment of the present invention configured as described above, the control unit includes an interruption mode that interrupts the projection of the image by the projector if the door sensor detects the opening of the bathroom door while the spatial presentation is being performed by the presentation unit. Thus, if the door sensor detects the opening of the bathroom door as the user attempts to leave the bathroom while the spatial presentation is being performed by the presentation unit, the interruption mode interrupts the projection of the image by the projector. Therefore, by providing the control unit with this interruption mode, it is possible to reduce the possibility that the light from the image projected by the projector will enter the eyes of a user attempting to leave the bathroom without the interruption mode being activated, causing the user to feel dazzled.

[0009] In one embodiment of the present invention, preferably, the presentation means further includes a speaker installed in the bathroom, and the presentation means performs spatial presentation of the bathroom by at least executing audio output that outputs sound from the speaker, and the interruption mode of the control unit also interrupts the output of sound from the speaker. According to one embodiment of the present invention configured as described above, the rendering means performs the bathroom spatial presentation by at least executing audio output that outputs sound from the speaker. This allows the rendering means to further enhance the spatial presentation effect by including sound output from the speaker. When the rendering means performs the bathroom spatial presentation by at least executing audio output that outputs sound from the speaker, the interruption mode of the control unit also interrupts the sound output from the speaker. As a result, if the door open / close detection sensor detects the opening of the bathroom door as the user attempts to leave the bathroom while the spatial presentation means is performing the spatial presentation, the interruption mode interrupts the sound output from the speaker. Therefore, by providing the control unit with this interruption mode, it is possible to prevent sound from the speaker from leaking beyond the bathroom and the dressing room when the bathroom door is opened.

[0010] In one embodiment of the present invention, preferably, the presentation means further includes lighting installed in at least one of the bathroom and the changing room, and the presentation means performs spatial presentation of the bathroom by at least executing lighting control that controls the light emitted from the lighting, and the control unit includes a safety lighting mode that turns on the lighting before or at the same time as a state in which no image is displayed on the image display unit, and that displays an image before or at the same time as a state in which all the lighting in the bathroom and the changing room are turned off, so that a state in which all the lighting in the bathroom and the changing room are turned off and a state in which no image is displayed on the image display unit do not occur simultaneously. According to one embodiment of the present invention configured as described above, the rendering unit performs at least lighting control to control the light emitted from the lighting, thereby creating a spatial effect in the bathroom. This allows the rendering unit to further enhance the spatial effect of the rendering by including the light from the lighting. Furthermore, the control unit has a safety lighting mode that turns on the lighting when no image is displayed on the image display unit and displays an image on the image display unit when all the bathroom lights are turned off, so that the bathroom spatial rendering does not occur simultaneously when all the bathroom lights are turned off and when no image is displayed on the image display unit at the same time. This safety lighting mode of the control unit reduces the possibility of the bathroom's safety being compromised by the user's inability to see the bathroom and the changing room due to the bathroom's spatial rendering simultaneously occurring at an unintended time. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a bathroom system that improves the convenience of users in using spatial presentation and prevents users from using spatial presentation for long periods of time, making it easier for users to concentrate and enjoy the relaxing effects on their mind and body in a relatively short period of time.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Next, a bathroom system according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 is a side view showing a bathroom system according to one embodiment of the present invention, Figure 2 is a top view of a bathroom system according to one embodiment of the present invention, and Figure 3 is a side view showing the interior of a shower room of a bathroom system according to one embodiment of the present invention.

[0014] As shown in FIG. 1, a bathroom system 1 according to one embodiment of the present invention includes a shower room 4, which is a bathroom equipped with a device such as a hand shower for users to shower with, and a changing room 6 adjacent to the shower room 4. The shower room 4 is a shower room where users take showers. The shower room 4 may also be a bathroom equipped with a bathtub. For example, if the shower room 4 is a bathroom, a hand shower or the like, as described below, is installed in the bathroom. The shower room 4 may also be equipped with a flush toilet. A user who enters the shower room 4 is considered to be a user of the shower 12. Furthermore, the shower room 4 does not have a bathtub, so its spatial size (spatial volume) is smaller than that of a bathroom, etc. Therefore, the shower room 4 is designed to be more susceptible to sound reverberation and sound leakage than a bathroom, etc. The shower room 4 and changing room 6 are installed in facilities used by third parties other than the user, such as offices, coworking spaces, gyms, manga cafes, and hospitals. The shower room 4 and the changing room 6 may be a bathroom and a changing room installed in a residential home that are also used by family members other than the user. In this case, the changing room 6 may be formed from part of another room such as a hallway or a washroom.

[0015] The bathroom system 1 comprises a presentation means 8 that performs spatial presentation of the shower room 4 by executing at least one of video display, audio output, and lighting control, a start operation unit 10 that starts the spatial presentation of the shower room 4 by the presentation means 8 when operated by a user, a shower 12 that dispenses hot or cold water into the shower room 4, a shower operation unit 14 that accepts operation by a user to control the discharge of the shower 12, a backrest unit 16 that a user standing in the shower room 4 can lean against and rest against, an override operation unit 18 that does not change the sound output from the speaker 40 even when operated by a user, a door opening / closing detection sensor 20 that detects the opening and closing of a bathroom door 15 located between the shower room 4 and the changing room, and a control unit 22 that controls the presentation means.

[0016] As shown in Figure 1, shower 12 includes an overhead shower 17, a body shower 32, and a hand shower 34. Shower 12 may include at least one of these, or any combination of these. Shower 12 may be configured to include at least an overhead shower 17. Shower 12 may also be configured to include at least a body shower 32. Shower 12 may also be configured to include at least a hand shower 34.

[0017] Next, we will explain the overhead shower 17 with reference to Figures 1, 4, and 5. As shown in Figure 1, the overhead shower 17 is installed facing downward on the ceiling surface 4a of the shower room 4. The overhead shower 17 does not have a spray plate and is equipped with a straightening member that converges the discharged hot or cold water into a single stream.

[0018] As shown in Figures 4 and 5, overhead shower 17 is equipped with a water outlet forming member 21 that forms water outlet 19 (which opens downward in Figure 4). Inside water outlet forming member 21, a first flow straightening member 24, a second flow straightening member 25, and an exposed flow straightening member 26 are provided as flow straightening members that straighten the flow of water. Overhead shower 17 forms a flow path structure that omits a spray plate.

[0019] As shown in particular in Figure 5, the first straightening member 24 is composed of a disk-shaped member, with the central portion being a shielding portion 43, and 16 water passage holes 44 extending in the direction of water flow arranged in a circumferential direction in the outer peripheral region, and 8 water passage holes 45 extending in the direction of water flow arranged in a circumferential direction on a concentric circle of approximately half the diameter.

[0020] The second flow rectifying member 25 is formed by stacking four meshed flow rectifying nets 51. The second flow rectifying member 25 is disposed adjacent to the downstream side of the first flow rectifying member 24.

[0021] 4, a water supply channel 23 for supplying water is provided upstream of the first straightening member 24. In this embodiment, the water supply channel 23 is formed inside a water supply channel forming member 31 that is arranged adjacent to the upstream side of the water outlet forming member 21. The water supplied from the water supply channel 23 collides with the shielding portion 43 and can be retained in the first retention chamber 41.

[0022] 4 and 5, the exposed flow straightening member 26 is made of an elastic material. The exposed flow straightening member 26 has a cylindrical outer peripheral flow straightening surface 61 in the area on the water outlet 19 side. The exposed flow straightening member 26 has a plurality of cylindrical hollow spaces 65 separated by partition walls 64 extending in the direction of water flow. In this embodiment, the plurality of cylindrical hollow spaces 65 are each configured such that each of the concentric annular areas in a cross-sectional view is further divided into a plurality of sections in the circumferential direction.

[0023] The outer peripheral straightening surface 61 forms an annular straightening space 66 between itself and the water outlet forming member 21. By adopting predetermined dimensional conditions, even if the water flow enters the annular straightening space 66 and contracts, the flow is sufficiently straightened within the straightening space 66, so that the overall straightening performance can be maintained.

[0024] After the water supplied from the water supply passage 23 collides with the shielding portion 43 of the first rectifying member 24, it temporarily remains in the first retention chamber 41. This causes water pressure to build up inside the first retention chamber 41. The water remaining in the first retention chamber 41 is then pushed out by the water from the upstream direction and flows out downstream through the water passage holes 44 and 45.

[0025] The water flowing out from the water holes 44 and 45 is divided into a flow that passes through the second straightening member 25 and goes straight to the water outlet 19, and a flow that flows toward the center of the second retention chamber 47 due to surface tension and the negative pressure generated inside. The latter flow toward the center is collected at the center, and then flows out through the second straightening member 25 to the water outlet 19.

[0026] As the water passes through the four straightening meshes 51 of the second straightening member 25, the velocity vector of the water flow is aligned in the direction of travel. The water then passes through the multiple cylindrical hollow spaces 65 of the exposed straightening member 26 and the annular straightening space 66 around the exposed straightening member 26, before being discharged from the water outlet 19. As a result, the hot or cold water discharged from the water outlet 19 becomes a single stream of water. This type of water flow from the overhead shower 17 forms a water film along the human body when it hits the water, enveloping the entire body and, if the water flow is warm, being effective in raising core body temperature.

[0027] In particular, a cylindrical outer peripheral straightening surface 61 is provided in the area of the outlet side 2 of the exposed straightening member 26, and an annular straightening space 66 is formed between the outer peripheral straightening surface 61 and the outlet forming member 21, which significantly suppresses the occurrence of water cracks when the water is discharged, and extremely high straightening performance can be achieved.

[0028] The water stream discharged from the spout 19 of the overhead shower 17 flows vertically from the ceiling to the floor while remaining cohesive as a single stream. Because the spout 19 of the overhead shower 17 is not provided with a sprinkler plate, the water stream discharged from the spout 19 is not sprayed by the sprinkler plate. Therefore, compared to the relatively loud sounds of water discharged when the spout plate splits the water into multiple streams, the sound of water impacting the user, and the sound of multiple water streams impacting the floor 4b, the sound of water impacting the floor 4b as in this embodiment is suppressed to a relatively quiet level. Furthermore, as shown in FIG. 2, the position where the water stream discharged from the overhead shower 17 impacts the floor 4b of the shower room 4 does not overlap with the drain outlet 28 provided on the floor 4b in a top view. The drain outlet portion 28 is formed by covering the drain outlet with a cover, but may be a drain outlet without a cover.

[0029] Next, the body shower 32 will be described with reference to FIGS. The body shower 32 is mounted on the side wall 4c of the shower room 4 and sprays water laterally. The body shower 32 has an angle adjustment function that adjusts the water spray angle, i.e., the water spray direction. The angle adjustment function of the body shower 32 allows adjustment of the water spray trajectory position, water spray direction, and the area where the water hits the user. The body shower 32 can spray water, for example, in a horizontal direction parallel to the backrest 16. The angle adjustment function of the body shower 32 allows water to be sprayed at various angles other than a horizontal direction parallel to the backrest 16. The angle adjustment function of the body shower 32 is configured so that the water spray trajectory and / or the area where the water hits the user falls within the central region C2 and lower region C3. The body shower 32 is provided in the central region C2, the lower region C3, or both the central region C2 and the lower region C3, of the upper region C1, the central region C2, and the lower region C3, which are defined by vertically dividing the side wall surface 4c into thirds. For example, at least one body shower 32 may be provided in the central region C2. Also, for example, at least one body shower 32 may be provided in the lower region C3. Also, for example, at least one body shower 32 may be provided straddling both the central region C2 and the lower region C3, thereby providing a position in both the central region C2 and the lower region C3. Furthermore, for example, a body shower 32 may be provided in both the central region C2 and the lower region C3, so that a body shower 32 is provided in each of the central region C2 and the lower region C3. Here, the body shower 32 is provided in a region other than the upper region C1.

[0030] The hand shower 34 is provided on a side wall surface 4c of the shower room 4. The hand shower 34 has a shower head 34b attached to the tip of a shower hose 34a extending from the side wall surface 4c.

[0031] The shower control unit 14 is mounted on the side wall 4c of the shower room 4. The shower control unit 14 includes a temperature and flow adjustment control unit 14a and a selector switch 14b. The temperature and flow adjustment control unit 14a includes a temperature adjustment handle that adjusts the set hot or cold water discharge temperature and a flow rate adjustment handle that adjusts the set hot or cold water discharge flow rate. The temperature and flow adjustment control unit 14a is connected to a water supply source such as a water heater or tap. The selector switch 14b is located midway along the flow paths from the temperature and flow adjustment control unit 14a to the overhead shower 17, the body shower 32, and the hand shower 34, forming a three-path selector switch. That is, the selector switch 14b is configured to switch between the water supply path 23 (see FIG. 4 ), which is the flow path leading to the overhead shower 17, the flow path leading to the body shower 32, and the flow path leading to the hand shower 34. Therefore, the user can adjust the temperature and flow rate of the water discharged from the shower 12 by operating the temperature and flow control unit 14a, and can also select whether to discharge water from the overhead shower 17, the body shower 32, or the hand shower 34.

[0032] The production means 8 performs spatial production of the shower room 4. The production means 8 includes a projector 36 provided in the changing room, and an image display unit 38 that displays an image projected by the projector 36, the image display unit 38 being disposed between the changing room 6 and the shower room 4 and configured so that the projected image can be recognized from the shower room 4. The production means 8 performs spatial production of the shower room 4 by at least executing image display that causes the image projected by the projector 36 to be displayed on the image display unit 38.

[0033] The projector 36 is provided on the ceiling of the changing room 6. The projector 36 may also be provided on a side wall, floor, or shelf of the changing room 6. The projector 36 is positioned facing the image display unit 38 so that the projected image is displayed on the image display unit 38. The projector 36 communicates with the control unit 22 via infrared communication.

[0034] The video display unit 38 is configured to display video. The video display unit 38 is not limited to displaying moving images; it can also display still images and light emission states other than still images. The video display unit 38 is provided on the bathroom door 15 between the dressing room 6 and the shower room 4. For example, a translucent resin panel is provided inside the frame of the bathroom door 15, and the resin panel of the bathroom door 15 functions as the video display unit 38 that displays the video projected by the projector 36. When the video projected by the projector 36 is displayed on the bathroom door 15, the user can view the video displayed on the bathroom door 15 from the back side of the bathroom door 15. The video display unit 38 may be configured by forming the bathroom door 15 from a translucent or transparent glass plate or a transparent resin panel. The video display unit 38 may also be a monitor that displays an image itself. In this case, a monitor is embedded in the bathroom door 15, and the projector 36 can be omitted. This monitor is connected to the control unit 22 and can directly display the video. The video display unit 38 is not limited to being provided on the bathroom door 15, but may also be provided on the boundary wall 4d between the dressing room 6 and the shower room 4 or on another side wall 4c.

[0035] The production means 8 further includes a speaker 40 provided in the shower room 4. The speaker 40 outputs sound into the shower room 4. The production means 8 performs spatial production of the shower room 4 by at least executing audio output that causes sound to be output from the speaker 40.

[0036] The speaker 40 is mounted facing downward on the ceiling surface 4a of the shower room 4. The speaker 40 includes the audio equipment necessary for sound output. Two speakers 40 are provided. One speaker 40 is located on one side of the overhead shower 17, and the other speaker 40 is located on the other side of the overhead shower 17. The two speakers 40 are mounted equidistant from the overhead shower. The two speakers 40 are also positioned on a line B (see FIG. 2) parallel to the backrest 16. The two speakers 40 are positioned symmetrically with respect to a line A extending perpendicular to the backrest 16 and passing through the overhead shower. This allows sound to be output from symmetrical directions relative to a user using the backrest 16 or a user bathing in the overhead shower 17, making the sound easier for the user to hear and improving the sound quality. The speaker 40 is positioned near or above the estimated user's position, as described below, and more preferably directly above. By arranging the speakers 40 near and above the estimated position of the user, the user can more reliably hear the sound and the sound quality can be improved. The number of speakers 40 is not limited to two, and one, or three or more speakers may be provided.

[0037] The production means 8 further includes lighting provided in at least one of the shower room 4 and the changing room 6. The lighting irradiates light into the shower room 4 and / or the changing room 6. For example, in this embodiment, the production means 8 includes shower room lighting 42 provided in the shower room 4, changing room lighting 46 provided in the changing room 6, and indirect lighting 49 provided below the backrest 16. The production means 8 performs spatial production of the shower room 4 by at least executing lighting control that controls the light emitted from the shower room lighting 42 and / or the changing room lighting 46 and / or the indirect lighting 49.

[0038] The shower room light 42 is provided on the ceiling surface 4a of the shower room 4 facing downward. For example, the shower room light 42 is a downlight. Two shower room lights 42 are provided on the ceiling surface 4a. One of the shower room lights 42 is located on one side of the overhead shower 17, and the other shower room light 42 is located on the other side of the overhead shower 17. The two shower room lights 42 are provided equidistant from the overhead shower 17. The two shower room lights 42 are also located on a line E (see FIG. 2) that is parallel to the backrest 16. The two shower room lights 42 are located symmetrically with respect to a line A that extends perpendicular to the backrest 16 and passes through the overhead shower 17. This allows light to be irradiated from symmetrical directions onto a user using the backrest 16 or a user taking a shower under the overhead shower 17, preventing the user's shadow from obscuring their feet or the light used for spatial design from being obscured. Furthermore, a downlight serving as indirect lighting 49 is provided below the backrest 16 in the shower room 4. The indirect lighting 49 does not shine light directly at the user, but rather shines light downward from the backrest 16 to indirectly brighten the bathroom. The indirect lighting 49 may be provided in another position that does not project light directly at the user. If the indirect lighting 49 is not used for spatial design, its installation can be omitted.

[0039] The shower room lighting switch 48 is provided in the changing room 6. The shower room lighting 42 is electrically connected to the shower room lighting switch 48, and by operating the shower room lighting switch 48, the user can switch the shower room lighting 42 on and off in order to normally switch the lights in the room on and off.

[0040] The changing room light 46 is provided facing downward on the ceiling surface 6a of the changing room 6. For example, the changing room light 46 is a downlight. One changing room light 46 is provided on the ceiling surface 6a. A changing room light switch 50 is also provided in the changing room 6. The changing room light 46 is electrically connected to the changing room light switch 50, and the user can switch the changing room light 46 on and off by operating the changing room light switch 50, for normal switching of the room lights on and off. The changing room light 46 also communicates with the control unit 22 via infrared communication. Note that multiple changing room lights 46 may be provided.

[0041] As shown in FIG. 3 , the start operation unit 10 functions as an output start operation unit that, when operated by a user, starts the output of sound from the speaker 40. The start operation unit 10 is provided on the side wall surface 4c. The start operation unit 10 has three push buttons: a first switch 10a, a second switch 10b, and a third switch 10c. Each of the three switches, the first switch 10a, the second switch 10b, and the third switch 10c, is electrically connected to the control unit 22. The first switch 10a, the second switch 10b, and the third switch 10c, correspond to a first spatial presentation mode, a second spatial presentation mode, and a third spatial presentation mode, respectively. When the first switch 10a, the second switch 10b, and the third switch 10c are pressed, the control unit 22 executes the first spatial presentation mode, the second spatial presentation mode, and the third spatial presentation mode, which will be described later. In other words, a spatial presentation including a preset sound output is started, and sound output from the speaker 40 is started. The start operation unit 10 may have two or four or more switches, or may have only one switch. If the user presses another switch (switch ON operation) during a certain spatial presentation, the currently running spatial presentation mode (for example, the first spatial presentation mode) will be terminated midway, and a different spatial presentation mode (for example, the second spatial presentation mode) will be executed.

[0042] The invalid operation unit 18 is provided alongside the start operation unit 10 on the side wall surface 4c. The invalid operation unit 18 has the appearance of a volume adjustment unit that can change the sound output from the speaker 40, but does not effectively function as a volume adjustment unit. The invalid operation unit 18 is not electrically connected to the control unit 22. Therefore, even if a user operates the invalid operation unit 18, the operation is invalid and the sound output from the speaker 40 cannot be changed. In this case, since it is the invalid operation unit 18 that is provided, the volume adjustment unit for changing the sound output from the speaker 40 is not essentially located in a position within the shower room 4 that is easy for the user to operate. As a variant, the function of the invalid operation unit 18 (the function of preventing the user from changing the sound output from the speaker 40) may be achieved by not locating the volume adjustment unit for changing the sound output from the speaker 40 in a position within the shower room 4 that is easy for the user to operate. As a modified example, invalid operation unit 18 may have a structure that invalidates any operation by the user, and may be configured so that it does not have the appearance of a volume adjustment unit that can change the sound output from speaker 40. In this case, invalid operation unit 18 is configured so that it is difficult for the user to recognize it as a volume adjustment unit, and so that operation input is also invalid. As a further modified example, invalid operation unit 18 may be disposed in shower room 4 as a volume adjustment unit that can change the sound output from speaker 40, and invalid operation unit 18 may be electrically connected to control unit 22, and the function of invalid operation unit 18 may be achieved by processing by control unit 22 not accepting or controlling changes to the sound output from speaker 40 for a predetermined period of time.

[0043] Door open / close detection sensor 20 is provided on the door frame of the wall to which bathroom door 15 is attached. Door open / close detection sensor 20 can detect the opening and closing of bathroom door 15. Door open / close detection sensor 20 is electrically connected to control unit 22, and control unit 22 can determine the open / close state of bathroom door 15 via door open / close detection sensor 20.

[0044] The control unit 22 functions as a control unit 22 that controls the sound output from the speaker 40. Sound output (sound output) includes voice output, video audio output, music sound output, etc. The control unit 22 is configured not to accept a change in the sound output of the speaker 40 by the user of the shower 12 after the speaker 40 starts outputting sound and before the sound output stops, and is configured to output sound from the speaker 40 at a preset output. "The control unit 22 is configured not to accept a change in the sound output of the speaker 40 by the user of the shower 12" includes a configuration in which the control unit 22 physically does not accept a request signal to change the sound output of the speaker 40, such as by arranging the override operation unit 18 or not arranging a switch for changing the sound output from the speaker 40. Furthermore, "The control unit 22 is configured not to accept a change in the sound output of the speaker 40 by the user of the shower 12" includes a configuration in which, even if a request signal to change the sound output of the speaker 40 is input to the control unit 22 through software processing of the control unit 22, the control unit 22 does not accept this change input or does not control the change for a predetermined period of time. This predetermined period is, for example, a period after the speaker 40 starts to output sound and before the speaker 40 stops outputting sound, and in another example, may be a period other than the initial setting or maintenance period.

[0045] By configuring the control unit 22 as described above, after the speaker 40 starts outputting sound but before the sound output stops, i.e., during the period when the spatial design is being carried out by the control unit 22, sound can be output at a volume intended by the installer of the bathroom system 1, using a preset output, regardless of the intention of the user of the shower 12.

[0046] The preset output is set as a sound output that is easy for the user to hear and does not become a noise for people outside the bathroom, taking into account the characteristics of the water discharge sound and / or the water hitting sound caused by the water discharge position and water discharge form according to the type of shower, the size of the shower room 4, the position of the speaker 40, etc. The preset output may be set as a single setting, or may be selected from a plurality of settings.

[0047] Being easily audible to the user is defined as the volume of the sound from speaker 40 being louder than the volume of the water spraying sound and / or the water hitting sound at the height of the user's ear at the estimated user position (for example, the height of the ear of a person of average height). The estimated user position is, for example, a position directly below overhead shower 17, a position where the user is leaning against backrest 16, a position directly in front of the direction in which water is sprayed from body shower 32, or a position where the image on image display unit 38 can be seen.

[0048] Being less likely to cause noise is defined as the volume of sound leaking outside the changing room 6 when the entrance door 52 of the changing room 6 is closed being preferably between 0 dB and 55 dB (a range below the volume of sound leakage that is less likely to be perceived as unpleasant), and more preferably between 0 dB and 45 dB (a range below the volume of sound leakage that is even less likely to be perceived as unpleasant).

[0049] The control unit 22 functions as a control unit that controls the light emitted from the shower room lighting 42 in the shower room 4 and / or the changing room lighting 46 in the changing room 6. When performing spatial design, the control unit 22 controls the shower room lighting 42 and / or the changing room lighting 46.

[0050] The control unit 22 functions as a control unit that controls the image display displayed on the image display unit 38. The image display includes the display of a moving image, the display of a still image, and the display of an illuminating state other than a still image (for example, a simple illuminating display).

[0051] The control unit 22 is electrically connected to the start operation unit 10 and receives input signals generated by operations on the start operation unit 10. The control unit 22 is also electrically connected to the speaker 40, the shower room lighting 42, the changing room lighting 46, the indirect lighting 49, the projector 36, and the door open / close detection sensor 20. These electrical connections may be made entirely or partially via wireless communication, such as infrared communication or other methods. Therefore, the control unit 22 may be located physically separate from the shower room 4 and the changing room 6 via the Internet, or may be provided in the form of a program on a server via the Internet. In other words, the control unit 22 may be provided in the form of a program and implemented on a server. In this embodiment, the control unit 22 incorporates a calculation device such as a CPU and a storage device such as a memory, and can control electrically connected devices based on a predetermined control program. For example, the control unit 22 stores control programs for implementing a first spatial presentation mode, a second spatial presentation mode, a third spatial presentation mode, and other spatial presentation modes in the storage device. Furthermore, for example, the control unit 22 stores in the storage device a control program for executing control of an automatic termination mode, an interruption mode, a safety lighting mode, and the like.

[0052] Next, with reference to FIG. 6, the spatial presentation performed by the control unit 22 will be described. The spatial presentation is performed by the presentation means 8 by executing at least one of video display, sound output, and lighting control.

[0053] The control unit 22 has a first spatial rendering mode that executes, for example, video display on the video display unit 38, such as playing video images, sound output from the speaker 40, such as playing music, and lighting control, such as turning on all the lights in the shower room 4 and turning off the lights in the changing room 6. The control unit 22 also stores video content data to be displayed and sound content data to be output in the first spatial rendering mode.

[0054] Control unit 22 also has a second spatial rendering mode that executes, for example, video display on video display unit 38 such as playing video images, sound output from speaker 40 such as playing music, and lighting control such as turning on the lighting in shower room 4 using indirect lighting 49. Control unit 22 also stores video content data to be displayed and sound content data to be output in the second spatial rendering mode.

[0055] The control unit 22 also has a third spatial rendering mode that executes image display on the image display unit 38, such as playing moving images, sound output from the speaker 40, such as playing music, and lighting control, such as turning off the lights in the shower room 4. The control unit 22 also stores the image content data to be displayed and the sound content data to be output in the third spatial rendering mode. Without being limited to the exemplary spatial presentation modes described above, the control unit 22 can perform spatial presentation using any one, a combination of two, or a combination of three of video display, sound output, and lighting control.

[0056] Here, "performance" includes automatically controlling one of the video display, sound output, and lighting control to change from an ON state to an OFF state and / or from an OFF state to an ON state after the performance starts and before the performance ends, or automatically controlling the intensity of the light. For example, "performance" includes automatically changing the intensity of the light without executing video display or sound output. Furthermore, without being limited thereto, "performance" also includes simply playing a video display or sound output. For example, "performance" includes simply playing a video display or sound output without controlling the lighting. Furthermore, without being limited thereto, "performance" also includes executing a combination of at least two of the video display, sound output, and lighting control. For example, "performance" includes controlling the lighting to full on and then playing a video display or sound output. Note that during the execution of such spatial performance, the control unit 22 causes the speaker 40 to output sound at the preset output level as described above.

[0057] The control unit 22 has an automatic termination mode that automatically terminates the spatial design of the shower room 4 within a predetermined time after starting the spatial design based on an operation on the start operation unit 10. In the automatic termination mode, the control unit 22 automatically terminates the spatial design within a predetermined time, preferably between 15 seconds and 5 minutes, more preferably between 30 seconds and 3 minutes, such as 2 minutes, after the spatial design begins. Therefore, by the control unit 22 forcibly terminating the spatial design within such a relatively short predetermined time, the spatial design provides the user with a concentrated, short-term relaxing environment during the spatial design. The end of the spatial design gives the user a natural impression that their use of the shower room 4 has ended, discouraging users from using the shower room 4 for extended periods of time and encouraging them to use it for shorter periods of time. For example, in shower rooms 4 attached to offices or coworking spaces, this can discourage users from using the shower room 4 for extended periods of time and encourage them to use it for shorter periods of time. Allowing users to refresh themselves efficiently within a set period of time contributes to user convenience and also makes the shower room 4 accessible to other users by preventing one user from occupying the shower room 4 for extended periods of time. The automatic termination mode of the control unit 22 is not necessarily limited to one that terminates within a predetermined time, but may be controlled to terminate when a predetermined time has elapsed.

[0058] By providing the control unit 22 with an automatic termination mode, it is possible to omit the placement of a termination button that the user manually operates to terminate the spatial presentation in the normal manner. If the spatial presentation is set to terminate when the user operates the termination button, the spatial presentation will continue unless the user operates the termination button. In contrast, in this embodiment, the termination button is omitted, and the spatial presentation is automatically terminated within a predetermined time using the automatic termination mode, allowing the user to efficiently refresh within a set period of time. Furthermore, this control of the automatic termination mode makes the user aware that a predetermined time has passed, allowing the user to use the shower room 4 effectively. If the user wishes to use additional spatial presentations, they can execute additional spatial presentations by further operating the start operation unit 10. Therefore, if the user wishes to further refresh themselves, they can use additional spatial presentations after being aware that a predetermined time has passed.

[0059] The control unit 22 has an interruption mode that interrupts the projection of images by the projector 36 when the door open / close detection sensor 20 detects the opening of the bathroom door 15 while the spatial presentation is being performed by the presentation unit 8. The interruption state caused by the interruption mode of the control unit 22 includes not only a state in which the projector 36 is stopped, but also a state in which the projection of images is interrupted and a black screen (a screen image in which most of the screen is basically black) is projected, and a state in which the projector 36 is operating but the image projection is interrupted by the mute function and the projected image disappears. The interruption mode of the control unit 22 reduces the possibility of a user who opens the bathroom door 15 being dazzled by the lack of light projected from the projector 36 or the projection of a black screen image. The interruption mode may stop the operation of the projector 36 after interrupting the operation of the projector 36. The interruption state caused by the interruption mode of the control unit 22 also includes a state in which the projector 36 is stopped without the intention of resuming it.

[0060] The interruption mode also interrupts sound output by speaker 40. That is, when door open / close detection sensor 20 detects the opening of bathroom door 15 while spatial presentation is being performed by presentation means 8, control unit 22 interrupts sound output by speaker 40 in the interruption mode. Therefore, by providing the control unit with this interruption mode, when bathroom door 15 is opened, sound from speaker 40 can be prevented from leaking from shower room 4 to changing room 6 and even beyond entrance door 52 of changing room 6.

[0061] The control unit 22 is provided with a safety lighting mode that turns on the lights (shower room lighting 42 and / or changing room lighting 46) before or at the same time as the image display unit 38 is not displayed on the image display unit 38, so that the lights in at least one of the shower room 4 and the changing room 6 are not turned off and no image is displayed on the image display unit 38 at the same time, and that turns on the images on the image display unit 38 before or at the same time as all the lights in the shower room 4 and the changing room 6 are turned off.

[0062] In the safety lighting mode, the control unit 22 determines when no image is displayed on the image display unit 38, and also determines when all of the shower room lighting 42, the changing room lighting 46, and the indirect lighting 49 (or, if only one or two of these are provided, all of these lights) are turned off. Note that the safety lighting mode does not necessarily require the lights to be turned off and the image to be displayed on the image display unit 38 to be switched on simultaneously; a time difference is acceptable. In other words, as long as the lights are turned off and the image is not displayed on the image display unit 38 at the same time, the control unit 22 may first turn on the lights in the shower room 4 at the end of the spatial presentation, and then turn off the image display on the image display unit 38. This safety lighting mode of the control unit 22 reduces the possibility that the image will not be displayed on the image display unit 38 at a time unintended by the user due to the spatial design of the shower room 4, and all lights in the shower room 4 and changing room 6 will be turned off at the same time, preventing the user from seeing inside the shower room 4 and changing room 6, thereby reducing the possibility of the user's safety being reduced.

[0063] Next, the operation (function) of bathroom system 1 according to one embodiment of the present invention will be described with reference to FIGS. Figure 7 is a timing chart showing the operational states of the start operation unit, bathroom door 15, door open / close detection sensor 20, projector 36, lighting, and sound output over time when spatial presentation by the control unit is continued until it is terminated after a predetermined time has elapsed in a bathroom system according to one embodiment of the present invention. Figure 8 is a timing chart showing the operational states of the start operation unit, bathroom door 15, door open / close detection sensor 20, projector 36, lighting, and sound output over time when spatial presentation by the control unit is interrupted before it is terminated after a predetermined time has elapsed in a bathroom system according to one embodiment of the present invention. In Figures 7 and 8, the vertical axis shows changes in whether or not a start operation was performed on the start operation unit, whether the bathroom door 15 is open or closed, whether the state of the bathroom door 15 detected by the door opening / closing detection sensor 20 is ON or OFF, whether the projection of the projector 36 is ON (projection is occurring) or OFF (projection is not occurring), whether the lighting is ON (lighting is on) or OFF (lighting is not on), and whether the sound output is ON (sound is being output) or OFF (sound is not being output), and the horizontal axis shows the passage of time.

[0064] First, as shown in Figs. 2 and 7, a case will be described in which spatial rendering by the control unit is continued until it is terminated after a predetermined time has elapsed. A user who wishes to use the shower 12 enters the changing room 6 through the entrance door 52 from the shared space F on the office side (see Figure 2). After the user enters the changing room 6, the entrance door 52 is closed. The user operates the changing room light switch 50 to turn on the changing room light 46. The user undresses in the changing room 6, opens the bathroom door 15, and enters the shower room 4. The user operates the shower room light switch 48 (see Figure 1) to turn on the shower room light 42. After entering the shower room 4, the user closes the bathroom door 15. The user then operates the shower operation unit 14 to take a hot or cold shower using the water discharged from the overhead shower 17, body shower 32, or hand shower 34.

[0065] Thus, at a point in time (for example, time T0) before the user of shower room 4 performs the spatial presentation, as shown in Figure 7, start operation unit 10 is in a no-start operation state where no start operation has been performed, door open / close detection sensor 20 is in an OFF state, control unit 22 determines that bathroom door 15 is closed, image projection by projector 36 is in an OFF state, changing room light 46 and shower room light 42 are on, and sound output by speaker 40 is in an OFF state.

[0066] The user can execute spatial presentation of the shower room 4 using the presentation means 8 at any time before, during, or after using the shower 12. As shown in FIG. 7, a user who wishes to execute spatial presentation selects one of the first switch 10a, second switch 10b, or third switch 10c of the start operation unit 10 and presses the switch to start the presentation, as shown in FIG. 7. The control unit 22 determines that the start operation has been performed on the start operation unit 10 and executes the corresponding control. For example, when the third switch 10c of the start operation unit 10 is operated, the control unit 22 executes the third spatial presentation mode. Below, an example in which the control unit 22 executes the third spatial presentation mode will be described; however, the first spatial presentation mode, second spatial presentation mode, and other control modes can also be similarly controlled in accordance with the control program of the control unit 22 described above. At time T1, control unit 22 receives a signal indicating that door open / close detection sensor 20 is in the OFF state. This allows control unit 22 to determine that bathroom door 15 is closed, and because bathroom door 15 is closed as planned, control unit 22 determines that spatial presentation can be performed without sound leakage or images being projected directly onto the user, and can perform the spatial presentation.

[0067] At time T1, when the third switch 10c of the start operation unit 10 is operated, the control unit 22 starts the execution of the third spatial rendering mode. At time T1, the control unit 22 starts projection by the projector 36 and turns the projection of the projector 36 ON. The control unit 22 starts projecting an image by the projector 36 and starts displaying the image by the image display unit 38 so as to play video content corresponding to the third spatial rendering mode. Also, at time T1, the control unit 22 turns the sound output by the speaker 40 from OFF to ON. Thus, the control unit 22 can output sound by the speaker 40 in conjunction with the display of the image by the image display unit 38, thereby synchronizing the image and sound. At time T1, the control unit 22 executes the spatial rendering and starts measuring the passage of time for the spatial rendering in the automatic end mode. At time T1, the control unit 22 turns on the changing room lighting 46, the shower room lighting 42, and the indirect lighting 49, and immediately after the spatial design begins, all of the above lighting in the shower room 4 and the changing room 6 is turned off, making it difficult for users to see inside the shower room 4 and the changing room 6, thereby reducing the possibility of reducing the safety of the users.

[0068] When starting the execution of the third spatial presentation mode, the control unit 22 performs control to send operation signals to devices connected to the control unit 22 via wireless communication such as infrared communication, such as the projector 36 and changing room lights 46, multiple times at the timing of each operation. This reduces the possibility of communication errors occurring in wireless communication and reduces the possibility of devices not working. The control unit 22 performs similar control when executing other modes such as the first spatial presentation mode and the second spatial presentation mode.

[0069] The control unit 22 also executes origin adjustment control when starting the execution of the third spatial rendering mode. For example, the control unit 22 controls the shower room lighting 42 and / or the changing room lighting 46 and / or the indirect lighting 49 to a fully lit state through the origin adjustment control. Then, the control unit 22 changes the changing room lighting 46, the shower room lighting 42, etc. to an off state or an arbitrary on state. This eliminates the need for the control unit 22 to check the initial state of the changing room lighting 46 and the shower room lighting 42 when starting control, and also allows the lighting to be constantly changed from a fully lit state to a desired state, making control simple and reliable. The control unit 22 also executes similar control when executing other modes, such as the first spatial rendering mode and the second spatial rendering mode. The control unit 22 also executes origin adjustment control when starting the execution of the third spatial rendering mode. For example, the control unit 22 controls the projector 36 to always start control from the same menu selection screen through the origin adjustment control. This allows the control unit 22 to execute the spatial presentation mode by transitioning from the menu selection screen to each video content in a short period of time at the start of control. The control unit 22 also performs similar control when executing other modes such as the first spatial presentation mode and the second spatial presentation mode. Furthermore, when starting the execution of the third spatial rendering mode, the control unit 22 also executes origin adjustment control. For example, the control unit 22 controls the speaker 40 so that control always starts from outputting the same sound through origin adjustment control. This allows the control unit 22 to execute the spatial rendering mode by reliably transitioning from outputting the same sound to outputting each sound in a short period of time at the start of control, with the volume and other settings and timing determined. The control unit 22 also executes similar control when executing other modes such as the first spatial rendering mode and the second spatial rendering mode. This origin alignment control may be performed when each spatial presentation mode ends. By keeping the state of each device at the end of the mode constant, the state of the device when it is next activated can be reliably estimated, and the next spatial presentation mode can be executed quickly and reliably.

[0070] At time T2, the control unit 22 turns off the changing room lights 46 and the shower room lights 42, turning off all of the lights in the shower room 4 and the changing room 6. This further enhances the visual, sound, and lighting effects, further increasing the relaxing effect on the user. The control unit 22 continues to perform spatial presentation in the third spatial presentation mode after time T2. Time T2 is a time several to 10 seconds after time T1.

[0071] At time T3, the control unit 22 determines that a predetermined time has passed since the start of the spatial presentation (time T1) in the automatic end mode, and ends the spatial presentation in the third spatial presentation mode. This automatic end mode automatically ends the spatial presentation after the predetermined time has passed. This discourages users from using the system for long periods of time, making it easier to encourage users to use the system for short periods of time.

[0072] When the control unit 22 is about to end the spatial presentation, it switches the changing room lighting 46, the shower room lighting 42, and the indirect lighting 49 from OFF to ON (full on) in the safety lighting mode, thereby turning on all the lights in the shower room 4 and the changing room 6. At this time, the projector 36 continues to project light ON in the safety lighting mode so that the lights are not turned off and the image display unit 38 does not display any images at the same time. Note that, as long as the safety lighting mode prevents the lights from being turned off and the image display unit 38 from displaying any images at the same time, the changing room lighting 46 and the shower room lighting 42 may be turned on and the projector 36 may be turned OFF. Furthermore, at time T3, the control unit 22 switches the sound output from the speaker 40 from ON to OFF. At time T3, the spatial presentation in the third spatial presentation mode has ended. The user is still in the shower room 4 and has not opened the bathroom door 15.

[0073] At time T4, control unit 22 changes the projection of projector 36 from the ON state to the OFF state. Time T4 is the time several to ten seconds after time T3. At time T3, the spatial presentation in the third spatial presentation mode ends, but from time T3 to time T4, the video display unit 38 displays the video of the end screen or a standby state image. After time T4, the user opens bathroom door 15, leaves shower room 4, and moves to changing room 6.

[0074] Next, as shown in FIG. 8, a case will be described in which the spatial rendering by the control unit 22 is interrupted before it is completed due to the lapse of a predetermined time. The control by the control unit 22 from time T0 to time T2 is the same as the control shown in FIG. 7, and therefore a description thereof will be omitted. Normally, as shown in FIG. 7, at time T3, the control unit 22 would determine in automatic end mode that a predetermined time has elapsed since the start of the spatial presentation (time T1), and would end the spatial presentation in the third spatial presentation mode. However, there may be cases where the user ends or stops using the shower room 4 and leaves the shower room 4 before the time T3 at which such a predetermined period of time has elapsed.

[0075] Until time T5 (a time before time T3), control unit 22 continues the spatial presentation in the third spatial presentation mode. At time T5, the user attempts to leave shower room 4 and changes bathroom door 15 from a closed state to an open state. Door open / close detection sensor 20 changes from an OFF state to an ON state, and control unit 22 recognizes that bathroom door 15 has been opened. This causes control unit 22 to execute the interruption mode and interrupt the projection of the image by projector 36. Projection by projector 36 remains ON, but the projection of the image screen is interrupted and switched to a black screen. This interruption mode reduces the possibility of a user exiting bathroom door 15 being dazzled by the lack of light or the projection of a black image from projector 36.

[0076] At time T5, in order to prevent the lights from being turned off and the image not being displayed on the image display unit 38 from occurring simultaneously in the safety lighting mode, the control unit 22 changes the changing room light 46 and the shower room light 42 from OFF to ON, i.e., full lighting, so that all the lights in the shower room 4 and the changing room 6 are turned on. Also, at time T5, the control unit 22 changes the sound output from the speaker 40 from ON to OFF in the interruption mode. This prevents sound from leaking from the shower room 4 to the changing room 6 and further to the outside of the entrance door 52 of the changing room 6 when the bathroom door 15 is opened.

[0077] At time T6, the control unit 22 uses the mute function to erase the projected image. Therefore, the control unit 22 changes the projection of the projector 36 from the ON state to the OFF state. At this time, the control unit 22 may stop the operation of the projector 36. After that, the user moves to the changing room 6, and the control unit 22 returns to the state before the spatial presentation was performed.

[0078] According to the bathroom system 1 of the embodiment of the present invention described above, the user can start the spatial presentation of the shower room 4 by the presentation means 8 by operating the start operation unit 10. This improves convenience by allowing the user to adjust the timing of their use of the spatial presentation, and provides the user with more freedom to decide how to use the spatial presentation, compared to when the spatial presentation is automatically started upon entering the shower room 4. Furthermore, the control unit 22 has an automatic end mode that automatically ends the spatial presentation within a predetermined time after starting the spatial presentation of the shower room 4 based on the operation of the start operation unit 10. This automatic end mode of the control unit 22 prevents the user from using the spatial presentation for long periods of time, making it easier for the user to concentrate and enjoy the relaxing effects on both body and mind in a relatively short period of time.

[0079] Furthermore, in bathroom system 1 according to one embodiment of the present invention, presentation means 8 performs spatial presentation of shower room 4 by at least executing image display, in which the image projected by projector 36 is displayed on image display unit 38. In this way, presentation means 8 can improve the presentation effect of the spatial presentation by presentation including image display.

[0080] Furthermore, in bathroom system 1 according to one embodiment of the present invention, control unit 22 is provided with an interruption mode that interrupts the projection of images by projector 36 if door open / close detection sensor 20 detects the opening of the bathroom door while spatial presentation is being performed by presentation means 8. As a result, if door open / close detection sensor 20 detects the opening of the bathroom door as a user attempts to leave shower room 4 while spatial presentation is being performed by presentation means 8, the interruption mode interrupts the projection of images by projector 36. Therefore, by providing control unit 22 with this interruption mode, it is possible to reduce the possibility that light from the image projected by projector 36 will enter the eyes of a user attempting to leave shower room 4 without the interruption mode being activated, causing the user to feel dazzled.

[0081] Furthermore, in bathroom system 1 according to one embodiment of the present invention, rendering means 8 performs spatial design of shower room 4 by at least executing audio output that outputs sound from speaker 40. This allows rendering means 8 to further enhance the spatial design effect by including sound output from speaker 40. When rendering means 8 performs spatial design of shower room 4 by at least executing audio output that outputs sound from speaker 40, the interruption mode of control unit 22 also interrupts sound output from speaker 40. As a result, if the door open / close detection sensor 20 detects the opening of the bathroom door as the user attempts to exit shower room 4 while spatial design is being performed by rendering means 8, the interruption mode interrupts sound output from speaker 40. Therefore, by providing control unit 22 with this interruption mode, it is possible to prevent sound from speaker 40 from leaking beyond the shower room 4 and the changing room to the outside when the bathroom door is opened.

[0082] Furthermore, in the bathroom system 1 according to one embodiment of the present invention, the rendering unit 8 performs spatial design for the shower room 4 by at least controlling the light emitted from the lighting. This allows the rendering unit 8 to further enhance the spatial design effect by including the light from the lighting. Furthermore, the control unit 22 has a safety lighting mode that turns on the lighting when no image is displayed on the image display unit 38 and displays an image on the image display unit 38 when all the lights in the shower room 4 are turned off, so that the state in which all the lights in the shower room 4 are turned off and the state in which all the lights in the shower room 4 are turned off do not occur simultaneously. This safety lighting mode of the control unit 22 reduces the possibility of the user's safety being compromised by the spatial design of the shower room 4 causing the image display unit 38 to simultaneously display no image and all the lights in the shower room 4 to be turned off at an unintended time.
