[0002] BACKGROUND ART A remote control device (aerial image display device) that displays an operation unit (keypad surface) operated by a user as a floating image is known (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-134843 Summary of the Invention [Problem to be solved by the invention]

[0004] It is conceivable that such a remote control device could be used in a toilet. However, the range (viewing angle) within which the aerial image displayed by the remote control device can be seen is limited. Therefore, for example, a user sitting on the toilet seat would have to change their position to view the aerial image, which could make the remote control device less convenient to use.

[0005] The present invention has been made based on the recognition of such problems, and has an object to provide a toilet remote control device and a toilet device that can improve usability. [Means for solving the problem]

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, like components are designated by like reference numerals and detailed descriptions thereof will be omitted where appropriate. FIG. 1 is a perspective view showing a toilet room equipped with a toilet unit according to an embodiment. As shown in Figure 1, the toilet unit 1 includes a toilet device 10, a cabinet 200, a paper holder 300, and a hand washing basin 400. The toilet device 10 includes a toilet bowl 11, a main body 13, and a toilet remote control device 30 (hereinafter referred to as the remote control device 30).

[0021] The toilet bowl 11 is attached to, for example, the floor surface FS of the toilet room TR. The toilet bowl 11 may also be attached to the wall behind the toilet bowl 11. The toilet bowl 11 may also be attached to, for example, a position away from the floor surface FS of the toilet room TR. A main body 13 is placed on the toilet bowl 11.

[0022] The main body 13 has a casing 14, and a toilet seat 15 and toilet lid 17 that are rotatably supported on the casing 14. The toilet seat 15 is placed on top of the toilet bowl 11. The toilet lid 17 is placed on top of the toilet bowl 11 so as to cover the toilet seat 15. Figure 1 shows the toilet seat 15 and toilet lid 17 in the lowered position. Note that "up," "down," "front," "back," "left," and "right" refer to directions seen from a user sitting on the toilet seat 15 with the toilet lid 17 facing away from them.

[0023] The cabinet 200 is disposed in the toilet room TR. Specifically, the cabinet 200 is disposed to the side of the toilet bowl 11. The cabinet 200 is attached, for example, to either the left or right side wall SW of the toilet room TR. In this example, the cabinet 200 is attached to the right side wall SW of the toilet bowl 11. The cabinet 200 may also be attached to the left side wall of the toilet bowl 11.

[0024] A hand washing basin 400 is provided on the upper surface side of the counter 200a of the cabinet 200. The cabinet 200 also has a remote control device 30 (described later) provided therein, and a paper holder 300 is disposed below the remote control device 30.

[0025] The toilet room TR is provided with a door (not shown) for entering and exiting the toilet room TR. The door is provided, for example, on the front wall of the toilet room TR. The door may be provided on the side wall opposite the side wall SW on which the cabinet 200 of the toilet room TR is provided. The door is provided, for example, in a position that does not overlap with the toilet bowl 11 in the left-right direction.

[0026] FIG. 2 is a block diagram showing a communication system of the toilet device. The main body unit 13 has a human body detection sensor 20 that detects a user entering the toilet room TR, a seating detection sensor 21 that detects a user sitting on the toilet seat 15, a communication unit 23 that communicates with the remote control device 30, and a controller 25 that controls the communication unit 23.

[0027] Furthermore, the main body 13 has various functional parts as needed, such as a heated toilet seat function for heating the toilet seat 15, a private parts washing function for washing the private parts of a user seated on the toilet seat 15, a warm air function for drying the private parts, and a cleaning function for cleaning the toilet bowl 11. These functional parts are controlled by, for example, a controller 25. The functional parts of the main body 13 may be provided inside the toilet bowl 11.

[0028] The human body detection sensor 20 can detect a user present in the toilet room TR. In other words, the human body detection sensor 20 can detect a user who enters the toilet room and approaches the toilet bowl 11. As such a human body detection sensor 20, for example, a pyroelectric sensor, a microwave sensor, an ultrasonic sensor, or a distance measuring sensor (infrared projector sensor) can be used.

[0029] The human body detection sensor 20 transmits the presence or absence of a human body in the toilet room TR to the controller 25. The human body detection sensor 20 only needs to be able to detect a user who has entered the toilet room TR, and may be provided in, for example, the cabinet 200.

[0030] The seating detection sensor 21 detects whether a person has sat on or left the toilet seat 15. The seating detection sensor 21 may be a microwave sensor, a distance measuring sensor (infrared projector sensor), an ultrasonic sensor, a tact switch, a capacitance switch (touch sensor), a distortion sensor, or the like.

[0031] When using contact sensors such as tactile switches, electrostatic sensors, and strain sensors, these contact sensors are provided on the toilet seat 15. When a user sits on the toilet seat 15, the user's weight presses the tactile switch. Alternatively, the user comes into contact with the electrostatic sensor. Alternatively, the user's weight applies pressure to the strain sensor. Electrical signals from these sensors can detect whether the user is sitting or leaving the seat.

[0032] The seating detection sensor 21 transmits the user's sitting on and leaving the toilet seat 15 to the controller 25. Note that the seating detection sensor 21 only needs to be able to detect the user sitting on and leaving the toilet seat 15, and when a microwave sensor or a distance measuring sensor is used, the sensor may be provided in the cabinet 200, for example.

[0033] The communication unit 23 is connected to the controller 25. The communication unit 23 receives a command signal transmitted from the remote control device 30. The communication unit 23 also transmits to the remote control device 30, for example, detection of entry into the toilet room TR by the human body detection sensor 20 and detection of sitting on and leaving the toilet seat 15 by the seat detection sensor 21.

[0034] The controller 25 controls various functional units provided in the main body 13. Various control programs for operating the functional units are stored in the controller 25. The controller 25 is connected to the human body detection sensor 20, the seating detection sensor 21, the communication unit 23, and the various functional units.

[0035] For example, when a human body detection signal is transmitted from the human body detection sensor 20, the controller 25 opens the toilet lid 17. The controller 25 also activates the functional units based on command signals transmitted from the remote control device 30. Furthermore, the controller 25 causes the communication unit 23 to transmit to the remote control device 30 the presence or absence of a human body in the toilet room TR and the presence or absence of a person sitting on the toilet seat 15.

[0036] FIG. 3 is a front view showing the positional relationship between the toilet bowl and the remote control device. FIG. 4 is a side view showing the positional relationship between the toilet bowl and the remote control device. The remote control device 30 is operated to activate the functional units of the main body 13. The remote control device 30 may also be used to turn on and off the lights in the toilet room TR, for example. The remote control device 30 is located above a paper holder 300 that holds toilet paper TP, and is provided on the underside of the counter 200a of the cabinet 200. The remote control device 30 may also be provided on a side wall SW of the toilet room TR.

[0037] The remote control device 30 is disposed above the toilet seat 15. For example, if the height H1 from the floor surface FS to the upper surface (seat surface) of the toilet seat 15 is 420 mm, the height H2 of the remote control device 30 can be approximately 660 mm. As shown in FIG. 4, the remote control device 30 is located to the side of the toilet bowl 11 on which the toilet seat 15 is placed, with at least a portion of the remote control device 30 disposed forward of the center OO of the toilet seat opening 15a in the front-to-rear direction. In this example, the entire remote control device 30 is disposed forward of the center OO of the toilet seat opening 15a in the front-to-rear direction. This allows the remote control device 30 to be located in a position that is easy for a user seated on the toilet seat 15 to operate.

[0038] 3 and 4, a description will be given of a gaze point distribution 500 of a user seated on the toilet seat 15. The gaze point distribution 500 is a distribution range depending on the seating height of the user seated on the toilet seat 15, for example.

[0039] As shown in FIG. 3, the vertical range of viewpoint distribution 500 can be greater than or equal to height H3 and less than or equal to height H4 from the top surface (seat surface) of toilet seat 15. For example, if height H1 from floor surface FS to toilet seat 15 is 420 mm, height H3 can be 520 mm and height H4 can be 1020 mm. The horizontal range of viewpoint distribution 500 can be greater than or equal to distance L1 and less than or equal to distance L2 from the surface of remote control device 30 (surface of cabinet 200). For example, distance L1 can be 280 mm and distance L2 can be 410 mm. As shown in FIG. 4, the front-rear range of viewpoint distribution 500 can be greater than or equal to distance L3 from the rear end of remote control device 30. For example, distance L3 can be 250 mm.

[0040] FIG. 5 is a plan view showing the viewing angle of the aerial image. FIG. 6 is a front view showing the viewing angle of the aerial image. FIG. 7 is a side view showing the viewing angle of the aerial image. Remote control device 30 displays guidance and operation switches related to the toilet room TR and toilet device 10 as aerial image 32. The viewing angle range and direction of aerial image 32 displayed by remote control device 30 is limited. Therefore, for example, if the viewing angle direction is set to the front of remote control device 30, a user sitting on toilet seat 15 will not be able to view aerial image 32 unless they change their position, which could make remote control device 30 difficult to use.

[0041] Therefore, center line AA of viewing angle α at which aerial image 32 is visible extends rearward from aerial image 32 and passes above toilet seat opening 15a. In other words, center line AA passes through viewpoint distribution 500. In this case, it is preferable that viewpoint distribution 500 is included within viewable range 35 at which aerial image 32 is visible. This allows a user seated on toilet seat 15 to view aerial image 32 without changing their position.

[0042] Next, the configuration of the remote control device 30 will be described. FIG. 8 is a perspective view showing a state in which an aerial image is formed from the toilet remote control device. Fig. 9 is an explanatory diagram showing an example of an image displayed as an aerial image. Fig. 9(a) and (b) show an example of a guide display displayed as an aerial image. Fig. 9(c) shows an example of an operation switch displayed as an aerial image. FIG. 10 is a cross-sectional view showing the internal structure of the housing of the toilet remote control device and the positional relationship between the aerial image and the paper holder. Figure 11 shows an enlarged view of the plate, Figure 11(a) is an enlarged perspective view of the plate, and Figure 11(b) is an enlarged front view of the plate.

[0043] Remote control device 30 includes a display device 40 that displays aerial image 32, a detection unit 50 that detects operations on aerial image 32, and a control unit 60 that transmits a command signal to main body unit 13 based on the operations detected by detection unit 50.

[0044] Display device 40 has a housing 42, a display unit 44 provided inside housing 42, and a plate 46 provided on the front surface of housing 42. Display device 40 also has a light-shielding film 48 that blocks light emitted from display unit 44, and a rotating unit 49 that rotates light-shielding film 48.

[0045] The housing 42 is fixed to the underside of the counter 200a of the cabinet 200. The display unit 44 is a display that displays images. The display unit 44 is connected to the control unit 60, and the display content is controlled by the control unit 60.

[0046] The image displayed on display unit 44 is displayed as aerial image 32. Aerial image 32 can be viewed within view range 35. The images displayed on display unit 44 may be, for example, operation switches 32a for rear washing, bidet washing, etc. as shown in FIG. 8, or guide displays 32b and 32c and flush switch 32d for flushing the toilet as shown in FIG. 9. Changes (timing) in the display content displayed on aerial image 32 will be explained later.

[0047] Plate 46 is provided on housing 42, located in front of display unit 44. Plate 46 extends upward from lower portion 42a of housing 42, for example. Plate 46 focuses the image displayed on display unit 44 as aerial image 32. The distance from display unit 44 to plate 46 is equal to the distance from aerial image 32 to plate 46. Plate 46 has a plurality of vertical mirror portions 46a extending in the up-down direction, and a plurality of horizontal mirror portions 46b extending perpendicular to vertical mirror portions 46a.

[0048] Plate 46 has a large number of micro-sized gratings 46c formed by vertical mirror portions 46a and horizontal mirror portions 46b arranged in the vertical and horizontal directions when viewed from the front. Plate 46 projects aerial image 32 by re-converging diffused light from display unit 44 using vertical mirror portions 46a and horizontal mirror portions 46b. Plate 46 forms aerial image 32 by utilizing retroreflection by vertical mirror portions 46a and horizontal mirror portions 46b.

[0049] As shown in FIG. 11(a), the viewing angle α of aerial image 32 is determined by the aspect ratio (B:C) of thickness dimension B to height dimension C of grid 46c and the distance between display unit 44 and plate 46. For example, viewing angle α increases as the distance between display unit 44 and plate 46 decreases. Viewing angle α is, for example, between 18 degrees and 56 degrees relative to the horizontal plane. Viewing angle α is, for example, 38 degrees. Viewing angle α is set depending on the distance and positional relationship between toilet 11 and remote control device 30.

[0050] Meanwhile, as shown in Figure 11(b), the direction of center line AA of viewing angle α of aerial image 32 is set by angle β between diagonal line DD of grid 46c and vertical line EE. Angles β are, for example, between 25 degrees and 65 degrees. Angles β are, for example, 45 degrees. By setting angle β in this manner, center line AA of viewing angle α can be directed diagonally upward and backward from aerial image 32 (see Figures 5 to 7).

[0051] As shown in Figure 5, center line AA can be tilted backward by angle γ when viewed from the front of remote control device 30. Angle γ is, for example, 15 to 55 degrees. For example, when angle β is 45 degrees, angle γ is 35 degrees. This allows viewpoint distribution 500 of a user seated on toilet seat 15 to be included within viewable range 35 of aerial image 32.

[0052] FIG. 12 is an explanatory diagram of a case where other aerial images are erased by a light-shielding film. FIG. 13 is an explanatory diagram of a case where the light-shielding film is rotated. 12 and 13 show schematic diagrams of the trajectory of light emitted from any point on display unit 44. The aerial image is displayed in front of plate 46 by combining the light emitted from the entire surface of display unit 44. Light-shielding film 48 is provided between display unit 44 and plate 46. Specifically, light-shielding film 48 is provided on the front surface side of display unit 44. By transmitting only light at specific angles, light-shielding film 48 eliminates viewable ranges 36, 37 of other aerial images that are formed separately from aerial image 32 by plate 46. In other words, light-shielding film 48 controls viewable ranges 35-37 of the aerial image.

[0053] Light emitted from display unit 44 forms an image depending on the angle of incidence on plate 46. If light-shielding film 48 is not provided, when center line AA of viewing angle α of aerial image 32 is directed backward (viewpoint distribution 500), another aerial image that can be seen in viewable range 36 where center line A1-A1 of the viewing angle faces forward due to dispersion of light from display unit 44 is displayed. This other aerial image is imaged in the same position as aerial image 32, and has the same display content as aerial image 32. Furthermore, viewable range 37 is formed between viewable range 35 of aerial image 32 and viewable range 36 of the other aerial image. The other aerial image that can be seen in viewable range 37 is a ghost image due to dispersion of light from display unit 44.

[0054] As shown in Fig. 12, light-shielding film 48 transmits only the light emitted from display unit 44 that is required to display aerial image 32 that is visible within viewable range 35. Specifically, light-shielding film 48 has transparent resin 48a and black resin 48b provided inside transparent resin 48a. Light-shielding film 48 is formed by laminating transparent resin 48a and black resin 48b. Transparent resin 48a is a portion that can transmit light. On the other hand, black resin 48b is a portion that cannot transmit light.

[0055] 12, black resin 48b is inclined from the rear to the front in a plan view. This allows light projecting aerial image 32 to pass through transparent resin 48a located between adjacent pieces of black resin 48b. On the other hand, light projecting other aerial images visible in view ranges 36 and 37 is blocked by black resin 48b.

[0056] The rotating unit 49 is provided, for example, below the light-shielding film 48. The rotating unit 49 rotates the light-shielding film 48. The rotating unit 49 is, for example, a motor, and is electrically connected to the rotary switch 70 via the control unit 60.

[0057] The rotary switch 70 is, for example, a contact switch, and is provided, for example, on the housing 42, as shown in FIG. 8. The rotating unit 49 can be operated by the rotary switch 70 provided, for example, on the housing 42. Note that the rotating unit 49 may also be one that can be rotated manually or mechanically. The rotary switch 70 and the rotating unit 49 are provided as needed.

[0058] Rotation unit 49 rotates light-shielding film 48 so as to turn it upside down along the surface of display unit 44. Light-shielding film 48 is in a first state when in the position shown in Figure 12, where center line AA of the viewing angle faces backward. When light-shielding film 48 is in the first state, viewable ranges 36, 37 of other aerial images that extend in a range separate from viewable range 35 of aerial image 32 are erased.

[0059] 13 , where center line A1-A1 of the viewing angle faces forward, is the second state of shading film 48. When shading film 48 is rotated from the first state to the second state by rotation unit 49, aerial image 32 and other aerial images visible in viewable range 37 are erased, and other aerial images visible in viewable range 36 are formed. When shading film 48 is in the second state, viewable range 35 of aerial image 32, which extends in a range separate from viewable range 36 of the other aerial images, and viewable range 36 of the other aerial images are erased.

[0060] Rotating unit 49 can flip light-shielding film 48, which is in the first state, upside down to change it from the first state to a second state. As shown in Fig. 13, when light-shielding film 48 is in the second state, black resin 48b is tilted from the front to the rear in a plan view. As a result, light projecting other aerial images visible in viewable range 36 is transmitted through transparent resin 48a located between adjacent pieces of black resin 48b. On the other hand, light projecting aerial image 32 visible in viewable range 35 and other aerial images visible in viewable range 37 is blocked by black resin 48b.

[0061] When light-shielding film 48 is in the first state, aerial image 32 can only be seen from above toilet seat 15. If aerial image 32 could only be seen from above toilet seat 15, this could be inconvenient for, for example, a cleaner who cleans toilet room TR.

[0062] Therefore, remote control device 30 is configured so that, by operating rotation switch 70, rotation unit 49 is activated to change light-shielding film 48 from the first state to the second state. This allows another aerial image to be displayed that can be seen in view range 36, where center line A1-A1 of the viewing angle faces forward. As a result, a cleaner or other person in front of toilet 11 can see the other aerial image, which is the same image as aerial image 32, from view range 36.

[0063] Detection unit 50 is provided on the front side of housing 42. Detection unit 50 detects operations on aerial image 32 visible in view range 35 and other aerial images visible in view range 36. As shown in Fig. 10 , detection range 50a of detection unit 50 faces aerial image 32 and the other aerial images. Detection unit 50 is, for example, an infrared sensor, an electrostatic sensor, or a microwave sensor.

[0064] Detection unit 50 detects, for example, that a hand has touched operation switch 32a displayed on aerial image 32. Detection unit 50 is connected to control unit 60, and transmits operations on aerial image 32 to control unit 60. Note that, although this example has been described using an example where detection unit 50 is provided in housing 42, it is sufficient for detection unit 50 to be able to detect operations on aerial image 32 or other aerial images, and so it may also be provided in cabinet 200, for example.

[0065] The control unit 60 is provided, for example, inside the housing 42. The control unit 60 may also be provided outside the housing 42. The control unit 60 is connected to the display unit 44, the rotation unit 49, the detection unit 50, the rotation switch 70, the start switch 72, and the communication unit 65. The control unit 60 stores various control programs for controlling the display unit 44, the communication unit 65, the rotation unit 49, etc. A plurality of control units 60 may be provided, one for each control.

[0066] The activation switch 72 is, for example, a contact switch, and is provided, for example, on the housing 42 (see FIG. 8). The activation switch 72 is a switch that activates (ON / OFF) the remote control device 30. Note that the activation switch 72 may also be a non-contact switch that uses, for example, an infrared sensor, an electrostatic sensor, or a microwave sensor.

[0067] Furthermore, housing 42 may be provided with change switch 74 that changes the display of aerial image 32 visible in view range 35 and other aerial images visible in view range 36. Change switch 74 is a non-contact switch that uses, for example, an infrared sensor, an electrostatic sensor, or a microwave sensor. For example, the display of aerial image 32 can be changed by holding a hand in front of change switch 74 or by moving it sideways. The function of change switch 74 may be included in detection unit 50. In such a case, the display content of aerial image 32 can be changed by sliding a hand over aerial image 32.

[0068] The control unit 60 changes the display content of the display unit 44 based on the state of the user and the operation of the remote control device 30 by the user. The control unit 60 also causes the communication unit 65 to transmit a command signal based on the operation detected by the detection unit 50. Furthermore, the control unit 60 operates the rotation unit 49 based on the command signal transmitted from the rotation switch 70. Note that these control processes may be performed by multiple control units.

[0069] Next, the positional relationship between aerial image 32 and paper holder 300 will be described with reference to FIG.

[0070] The paper holder 300 holds toilet paper TP and is located below the remote control device 30. Specifically, the paper holder 300 is attached to the lower part 42a of the housing 42 of the remote control device 30. The paper holder 300 may also be attached to the cabinet 200 or the side wall SW.

[0071] The paper holder 300 has a mounting part 301 that is attached to a mounting portion such as the housing 42 or the cabinet 200, a cover part 302 that is rotatably attached to the mounting part 301, and a paper mounting shaft 303 that is provided on the mounting part 301 and to which the toilet paper TP is attached. The paper mounting shaft 303 extends in the front-to-rear direction of the toilet room TR.

[0072] 10 , when viewed from direction F facing aerial image 32, paper holder 300 is configured so that at least a portion of paper holder 300 protrudes from aerial image 32. In other words, when viewed from direction F facing aerial image 32, paper holder 300 is not entirely hidden behind aerial image 32.

[0073] Specifically, when viewed from direction F facing aerial image 32, aerial image 32 is projected in a position that does not overlap paper attachment axis 303 of paper holder 300. In other words, aerial image 32 is projected so as not to come into contact with tangent line GG of paper attachment axis 303, which extends perpendicular to the extension line of aerial image 32.

[0074] The position at which aerial image 32 is projected is determined by the distance between display unit 44 and plate 46. Therefore, the distance between display unit 44 and plate 46 is set so that the bottom end of aerial image 32 does not contact tangent line GG of paper mounting axis 303.

[0075] This makes it possible to remove aerial image 32 and other aerial images from the path of the hand movement of a user seated on toilet seat 15 when picking up toilet paper TP. Therefore, it is possible to prevent a user seated on toilet seat 15 from accidentally touching operation switch 32a of aerial image 32 when picking up toilet paper TP.

[0076] Next, the operation control of the remote control device 30 that is executed from the time of entering the toilet room TR until the time of leaving the toilet room TR will be described. FIG. 14 is an explanatory diagram showing an example of the passage of time from the entry to the exit of a user who uses a toilet.

[0077] First, when control unit 60 of remote control device 30 receives a notification that a human body has been detected by human body detection sensor 20, it causes display unit 44 to display a notification display. This notification display is, for example, guidance display 32b shown in Fig. 9(a) or guidance display 32c shown in Fig. 9(b).

[0078] The notification display displayed on display unit 44 is imaged by plate 46 and projected as aerial image 32. That is, display device 40 projects aerial image 32 when entry into toilet room TR is detected.

[0079] As a result, when no human body is present in the toilet room TR, aerial image 32 is not displayed, thereby reducing power consumption. The user can view aerial image 32 (notification display) from visible range 35 before sitting on toilet seat 15. Note that aerial image 32 displayed upon entry detection may display a menu display such as operation switch 32a shown in Figure 8 or flush switch 32d shown in Figure 9(c) without displaying a notification display.

[0080] Next, when the control unit 60 receives a notification that the seating detection sensor 21 has detected a person sitting on the toilet seat 15, it changes the notification display displayed on the display unit 44 to a menu display. The menu display may be, for example, an operation switch 32a for private parts washing as shown in FIG. 8, or a flush switch 32d as shown in FIG. 9(c). In other words, the menu display provides information about the functions of the toilet room TR and displays the operation switches. A user seated on the toilet seat 15 can change the displayed operation switch 32a to the flush switch 32d by, for example, operating the change switch 74.

[0081] Furthermore, when control unit 60 receives notification that seating detection sensor 21 has detected a person sitting on toilet seat 15, it causes detection unit 50 to start accepting operations on aerial image 32. That is, when control unit 60 has not detected a person sitting on toilet seat 15, it disables operations on aerial image 32. On the other hand, when control unit 60 has detected a person sitting on toilet seat 15, it enables operations on aerial image 32.

[0082] In this case, power may be turned on to the detection unit 50 when it is detected that a user is seated on the toilet seat 15. Also, the control unit 60 may determine whether operation detection by the detection unit 50 is enabled or disabled depending on whether a user is seated on the toilet seat 15. This makes it possible to prevent erroneous operation caused by touching the operation switch 32a or the flush switch 32d when the user is not seated on the toilet seat 15, for example, in cases where a menu display such as the operation switch 32a is displayed after the user's entry is detected.

[0083] Here, remote control device 30 extends center line AA of viewing angle α of aerial image 32 diagonally upward and rearward from aerial image 32 toward viewpoint distribution 500 of a user seated on toilet seat 15. This allows a user seated on toilet seat 15 to view aerial image 32 without changing their position.

[0084] When the user touches operation switch 32a on aerial image 32, detection unit 50 detects the position of the user's finger and transmits a detection signal based on the operated switch to control unit 60. Based on the detection signal from detection unit 50, control unit 60 causes communication unit 65 to transmit a command signal to communication unit 23 of main body unit 13. Based on the command signal transmitted from remote control device 30, controller 25 activates functional units such as local cleaning and toilet flushing.

[0085] For example, after washing their private parts, a user may use toilet paper TP or use the warm air function to dry their private parts. As shown in FIG. 10 , aerial image 32 is projected above tangent line GG of paper attachment axis 303 of paper holder 300. This prevents the user from accidentally touching aerial image 32 (operation switch 32a) when reaching out for toilet paper TP. In this way, by setting the positional relationship between aerial image 32 and paper holder 300, it is possible to prevent malfunction of functional units.

[0086] When the user leaves toilet seat 15, seat detection sensor 21 transmits the seat removal detection to controller 25. Controller 25 transmits the seat removal notification to communication unit 65 of remote control device 30. In this case, even if control unit 60 of remote control device 30 receives the seat removal notification from seat detection sensor 21, it continues to display aerial image 32 (menu display) and to detect operations on aerial image 32 by detection unit 50 as long as human body detection sensor 20 is detecting a human body.

[0087] Human body detection sensor 20 monitors entry and exit into toilet room TR by detecting the presence or absence of a human body within toilet room TR. Therefore, when control unit 60 detects that a person has left toilet seat 15, it enables operation of aerial image 32 until it detects that the person has left toilet room TR. This prevents the remote control from becoming inoperable, for example, when performing a toilet flush after leaving toilet seat 15, making remote control device 30 easy to use.

[0088] Then, when the control unit 60 recognizes that the user has left the toilet room TR, it erases the display on the display unit 44 and disables (terminates) the acceptance of operations by the detection unit 50. This allows the remote control device 30 to save power.

[0089] FIG. 15 is an explanatory diagram showing an example of the time lapse from the entry to the exit of a cleaner who cleans a toilet room. If operation of the remote control device 30 is to be accepted by sitting on the toilet seat 15, it may become difficult for the cleaner to use the remote control device 30. Therefore, the remote control device 30 is designed so that operation acceptance can be enabled or disabled and the display content can be changed without sitting on the toilet seat 15.

[0090] 15, when control unit 60 of remote control device 30 receives a notification that a human body has been detected by human body detection sensor 20, it causes display unit 44 to display a notification display. This notification display is, for example, guide display 32b shown in FIG. 9(a) or guide display 32c shown in FIG. 9(b). In addition, control unit 60 enables detection by change switch 74.

[0091] The notification display displayed on display unit 44 is focused by plate 46 and projected as aerial image 32. In this case, center line AA of viewing angle α of aerial image 32 faces rearward. Therefore, the cleaner can rotate light-shielding film 48 from the first state to the second state by operating rotation switch 70. This causes remote-control device 30 to display another aerial image that can be viewed in viewing range 36 where center line A1-A1 of the viewing angle faces forward, as shown in FIG. 13 . As a result, the cleaner can view another aerial image with the same display content as aerial image 32 from viewing range 36 located in front of toilet bowl 11.

[0092] Next, upon detecting that activation switch 72 or change switch 74 has been operated, control unit 60 changes the notification display of other aerial images visible within visible range 36 to a menu display. Activation switch 72 is, for example, a contact-type switch such as a push button. On the other hand, change switch 74 is a non-contact switch that is switched from operation OFF to operation ON by waving a hand (gesture) in front of it. It is sufficient that at least one of activation switch 72 and change switch 74 is provided. Furthermore, upon detecting that activation switch 72 or change switch 74 has been operated, control unit 60 changes detection unit 50's acceptance of operations for other aerial images from disabled to enabled.

[0093] When detection unit 50 detects that switch 32d for displaying another aerial image has been touched, control unit 60 transmits a command signal to communication unit 23 of main body unit 13. Then, upon receiving the command signal, controller 25 executes toilet flushing.

[0094] Control unit 60 displays a menu of other aerial images visible within visible range 36 until a predetermined time has elapsed since activation switch 72 or change switch 74 was operated, and also enables acceptance of operation by detection unit 50. When a predetermined time has elapsed since activation switch 72 or change switch 74 was operated, control unit 60 erases the display on display unit 44, thereby erasing the other aerial images.

[0095] Furthermore, when a predetermined time has elapsed since the start switch 72 or the change switch 74 was operated, the control unit 60 changes the operation acceptance (operation detection) by the detection unit 50 from valid to invalid. This predetermined time is about several tens of seconds (for example, about 30 seconds).

[0096] This prevents the cleaner from accidentally operating the remote control when cleaning (maintaining) toilet room TR. The display of aerial image 32 and other aerial images and the presence or absence of detection by detection unit 50 are not limited to the passage of a predetermined time, and may also be operated by, for example, start switch 72 or change switch 74.

[0097] If the cleaner wishes to flush the toilet bowl while cleaning the toilet room TR, he or she can operate the start switch 72 or the change switch 74 to display other aerial images that can be seen within the viewing range 36 and enable the detection unit 50 to accept operations.

[0098] When the cleaner has finished cleaning the toilet room TR, he or she can return the light-shielding film 48 from the second state to the first state by operating the rotary switch 70. Then, when the human body detection sensor 20 detects that the cleaner has left the room, the control unit 60 erases the display on the display unit 44 and disables the operation acceptance (operation detection) of the detection unit 50.

[0099] In the above description, the light-shielding film 48 is rotated from the second state to the first state by operating the rotation switch 70. However, for example, when the human body detection sensor 20 detects that a cleaner has left the room, the control unit 60 may automatically activate the rotation unit 49 to rotate the light-shielding film 48 from the second state to the first state.

[0100] In this way, remote control device 30 can be made easy to use not only for users of toilet 11, but also for cleaners who clean and maintain toilet room TR. In particular, users of toilet 11 can operate the functional parts by operating aerial image 32 without touching remote control device 30, thereby improving reliability in terms of hygiene.

[0101] FIG. 16 is a cross-sectional view showing a modified example of a remote control device for a toilet. In the above-described embodiment, the light-shielding film 48 is provided on the front side of the display unit 44. However, the present invention is not limited to this, and for example, as in the modified example shown in Fig. 16, the light-shielding film 80 and the rotating unit 81 may be provided on the back side of the plate 46.

[0102] In the above-described embodiment, an example has been described in which the detection signals from the human body detection sensor 20 and the seating detection sensor are transmitted from the communication unit 23 of the main body 13 to the remote control device 30. However, the present invention is not limited to this example, and for example, if the human body detection sensor and the seating detection sensor are provided in the cabinet 200, a signal may be transmitted to the remote control device 30 from a communication unit provided in the cabinet 200 or the like.

[0103] In the above-described embodiment, the display unit 44 is a display whose display content changes. However, the present invention is not limited to this. For example, the display unit may only display a plurality of operation switches that operate the functional units. The display unit does not have to be a display, as long as the display content can be reflected by the plate.

[0104] In the above-described embodiment, an example has been described in which, when shading film 48 is in the first state, other aerial images visible in view range 36 and other aerial images visible in view range 37 (ghost images) are erased, and when shading film 48 is in the second state, aerial image 32 visible in view range 35 and other aerial images visible in view range 37 (ghost images) are erased. However, aspects of the present invention are not limited to this, and, for example, the shading film may erase only other aerial images that are ghost images. In such a case, rotation unit 49 is unnecessary.

[0105] In the above-described embodiment, an example was described in which, after sitting on the toilet seat 15, the menu is displayed and operation is accepted by the detection unit 50 until the user leaves the toilet room TR, even if the user leaves the toilet seat 15. However, the present invention is not limited to this, and for example, the menu may be displayed and operation may be accepted only while the user is sitting on the toilet seat 15. Furthermore, when the user leaves the toilet seat 15, the menu may be displayed and operation may be accepted until a predetermined time has elapsed.

[0106] In the above-described embodiment, an example has been described in which the light-shielding film 48 is rotated by the rotation switch 70. However, the present invention is not limited to this, and the light-shielding film 48 may be rotated automatically, for example. For example, the rotation unit 49 may place the light-shielding film 48 in the second state when it is not detected that a person is sitting on the toilet seat 15, and may place the light-shielding film 48 in the first state when it is detected that a person is sitting on the toilet seat 15.

[0107] As a result, when a user, cleaner, or the like enters toilet room TR, the other aerial image can be viewed from view range 36 while approaching toilet bowl 11. Furthermore, when the user sits on toilet seat 15, light-shielding film 48 is automatically rotated to the first state, allowing the user seated on toilet seat 15 to view aerial image 32. Therefore, remote control device 30 can be made easy to use.

[0108] In the above-described embodiment, the remote control device 30 is attached to the counter 200a of the cabinet 200. However, the present invention is not limited to this, and the remote control device 30 may be attached to a counter provided on the side wall SW, for example.

[0109] The above describes embodiments of the present invention. However, the present invention is not limited to these descriptions. Design modifications made by a person skilled in the art to the above-described embodiments are also included within the scope of the present invention as long as they incorporate the features of the present invention. For example, the shape, dimensions, materials, and arrangement of each element of the toilet remote control device and toilet device are not limited to those exemplified and can be modified as appropriate. Furthermore, each element of the above-described embodiments can be combined to the extent technically possible, and such combinations are also included within the scope of the present invention as long as they incorporate the features of the present invention.
