DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] 1. First embodiment (urinal device) A urinal device 1 of a first embodiment will be described with reference to the accompanying drawings.

[0010] The urinal device 1 of the first embodiment comprises a urinal 2 having a bowl portion 21, and a target forming means 3 forming a target for urine (see FIG. 1, etc.). The urine here is urine discharged toward the bowl portion 21 by a user standing in front of the urinal 2.

[0011] (urinal) In the urinal device 1 of the first embodiment, the urinal 2 is a wall-hung urinal. The front-rear direction D1, the left-right direction D2, and the up-down direction D3 used in the following description are based on a state in which the urinal 2 is fixed to the surface of a vertical wall 9, as shown in Figure 1.

[0012] The front-to-back direction D1 is the horizontal direction in which the vertical wall 9 and the urinal 2 are aligned. The left-to-right direction D2 is a direction perpendicular to the up-down direction D3 and the front-to-back direction D1. The front-to-back direction D1, the left-to-right direction D2, and the up-to-down direction D3 are perpendicular to each other. In the front-to-back direction D1, the direction in which the urinal 2 is positioned relative to the vertical wall 9 is the front, and the opposite direction is the rear.

[0013] In the urinal device 1 of the first embodiment, the urinal 2 is made of synthetic resin, but it is also possible to make it out of another material such as ceramic.

[0014] The urinal 2 has a bowl portion 21 formed in a concave shape for receiving urine from a user, a water outlet portion 22 configured to eject water into the bowl portion 21, and a drainage portion 23 configured to drain water that has flowed down the bowl portion 21. The bowl portion 21 is formed long in the vertical direction as a whole, with the water outlet portion 22 provided above the bowl portion 21 and the drainage portion 23 provided at the lower end portion of the bowl portion 21.

[0015] A drain trap is connected to the bottom of the urinal 2. The drain trap is connected to the drain portion 23 of the bowl portion 21 from below. A drain pipe is provided in the wall 9, and this drain pipe is connected to the drain portion 23 of the urinal 2 via the drain trap.

[0016] (Target configuration means) The target configuration means 3 is a means for configuring two targets T1 and T2 located at a distance from each other.

[0017] The two targets T1 and T2 are a first target T1 and a second target T2. The first target T1 is a target located away from the bowl portion 21. The second target T2 is a target located on the surface of the bowl portion 21 (in other words, the bowl surface).

[0018] The first target T1 is configured at a position farther from the bowl portion 21 of the urinal 2 than the second target T2. The first target T1 is located above the second target T2 and further forward than the second target T2. In other words, the first target T1 is located diagonally above and in front of the second target T2.

[0019] In the urinal device 1 of the first embodiment, as shown in Fig. 1, the first target T1 is located outside the space surrounded by the bowl portion 21, but the position of the first target T1 is not limited to this. The first target T1 may also be located within the space surrounded by the bowl portion 21.

[0020] The target construction means 3 includes an aerial imaging device 4 for constructing the first target T1, a detection unit 5 for detecting a user, a control unit 6 for controlling the aerial imaging device 4 based on the detection results of the detection unit 5, and a fixed target 71 that constructs the second target T2.

[0021] (Aerial Imaging Device) The aerial imaging device 4 is a device that images a first target T1 in the air away from the bowl portion 21. As shown in Fig. 1, the aerial imaging device 4 is installed in a portion of the urinal 2 behind the bowl portion 21.

[0022] 3, the aerial imaging device 4 includes a light source unit 41 including, for example, an LED 411 as a light source, and an optical plate 43 into which the light output from the LED 411 of the light source unit 41 is incident. The optical plate 43 has a structure that reflects the light incident from the light source unit 41 therein so that the light converges at a plane-symmetric position based on the optical plate 43.

[0023] Here, a portion 215 of the bowl portion 21 (see Figs. 1 and 2) is molded from a resin material having optical transparency. Specifically, by molding the urinal 2 by two-color molding using a resin material that does not have optical transparency and a resin material that has optical transparency, it is possible to impart optical transparency only to the portion 215 of the bowl portion 21. The optical plate 43 of the aerial imaging device 4 is disposed on the rear side of the portion 215 of the bowl portion 21.

[0024] Part 215 of bowl portion 21 is located above the portion of bowl portion 21 where second target T2 is configured, and has a vertically long shape. The shape of part 215 of bowl portion 21 is, for example, a vertically long and narrow rectangle. Part 215 of bowl portion 21 may be transparent or translucent.

[0025] According to the aerial imaging device 4, the light emitted from the light source unit 41 is reflected inside the optical plate 43 having a special structure, passes through the part 215 of the bowl unit 21, and is emitted to the outside, and then converges. As a result, an aerial image that functions as a first target T1 is generated in the air away from the bowl unit 21.

[0026] In the above, the light source unit 41 includes the LED 411 as a light source, but is not limited to this, and the light source unit 41 may include a light-emitting display such as a liquid crystal display or an organic EL display as a light source.

[0027] (Detection unit) The detection unit 5 is installed, for example, in a portion of the wall 9 adjacent to the urinal 2. The detection unit 5 includes a sensor 51 used to detect the distance to the user, and a sensor 52 used to detect the physique of the user. The sensors 51 and 52 may be installed separately.

[0028] The sensor 51 is, for example, a radio wave sensor. The radio wave sensor is configured to detect the distance to the user by using millimeter waves that have a high degree of linearity.

[0029] The sensor 52 is, for example, an infrared sensor. The detection unit 5 is configured to detect the temperature of the user by detecting far-infrared rays with the sensor 52, and to obtain the temperature distribution of the user's body. It is possible to detect the user's physique based on the temperature distribution of the user's body. For example, it is possible to detect the height of the user's lower abdomen based on an image of the temperature distribution of the user when urinating.

[0030] The portion where the detection unit 5 is installed is not limited to the wall 9 . For example, the detection unit 5 may be installed in the urinal 2 .

[0031] (Control unit) 1, the control unit 6 is housed in the upper end of the urinal 2. The control unit 6 controls the aerial imaging device 4 based on the detection result of the detection unit 5, and causes a first target T1 that functions as a target for urination to be imaged in the air.

[0032] When a user approaches the urinal 2 and urinates toward the bowl portion 21, the control unit 6 detects that the user is urinating based on the temperature distribution of the user's body detected by the detection unit 5, and also detects the user's physique (e.g., the height of the user's crotch). The control unit 6 controls the aerial imaging device 4 to irradiate light from the light source unit 41 to the optical plate 43, and to form an image of a first target T1 in the air in front of the part 215 of the bowl portion 21. The imaging position of the first target T1 is preferably selected so as to be a position suitable for the user's physique detected by the detection unit 5.

[0033] The imaging position of the first target T1 is selected, for example, by controlling at least one of the position and attitude of the light source unit 41 of the aerial imaging device 4, by controlling at least one of the position and attitude of the optical plate 43, or by controlling at least one of the overall position and attitude of the aerial imaging device 4, but other means can also be adopted as long as the imaging position of the first target T1 can be selected.

[0034] (fixed target) Fixed target 71 is fixed to bowl portion 21. Fixed target 71 is, for example, a sticker fixed to the surface of bowl portion 21. Fixed target 71 is preferably provided with a pattern or color that indicates that it is a target for urination.

[0035] The fixed target 71 is not limited to a sticker that is attached later, and may be, for example, a target printed on the bowl portion 21 or a target molded integrally with the bowl portion 21.

[0036] (Action and effect) In the urinal device 1 of the first embodiment, as described above, the first target T1 and the second target T2 are configured to be positioned at a distance from each other with respect to the urinal 2 having the bowl portion 21.

[0037] In conventional technology, urine is only released toward one target, so if the user is standing far away from the urinal 2 or is standing to the left or right, even if the urine hits the target, it is likely to splash back around. In contrast, with the urinal device 1 of the first embodiment, the user can release urine so that it hits both the first target T1 and the second target T2, effectively preventing urine from splashing back.

[0038] In other words, when the user starts to urinate, the user simply releases the urine so that it hits the second target T2, but after that, the first target T1 is imaged in the air, and by moving so that the urine also hits this first target T1, the user's position is guided to an appropriate position to prevent the urine from splashing back.

[0039] 2. Second embodiment A urinal device 1 of the second embodiment will be described with reference to the accompanying drawings. In the following description, the same components as those of the first embodiment will be given the same reference numerals and detailed description will be omitted.

[0040] 4, the light source unit 41 of the aerial imaging device 4 included in the urinal device 1 of the second embodiment includes a plurality of LEDs 412, 413, 414 that can emit light individually. The light output from the plurality of LEDs 412, 413, 414 toward the optical plate 43 is reflected inside the optical plate 43, and forms images at different positions in the air away from the bowl portion 21.

[0041] That is, in the urinal device 1 of the second embodiment, by selecting which of the multiple LEDs 412, 413, and 414 to emit light, it is possible to select the imaging position of the first target T1.

[0042] In the urinal device 1 of the second embodiment, when a user approaching the urinal 2 urinates toward the bowl section 21 from a position in front of the bowl section 21, the control section 6 detects the user's physique using the detection section 5, controls the aerial imaging device 4 based on the detection result, and causes any one of the multiple LEDs 412, 413, 414 to emit light so as to form an image at a position suitable for the user's physique. According to the urinal device 1 of the second embodiment, the above-mentioned simple configuration makes it possible to select the imaging position of the first target T1. Note that, in the illustrated example, three LEDs 412, 413, 414 arranged in a row are shown as the multiple LEDs 412, 413, 414, but this is merely a simplified illustration, and the number and arrangement of the LEDs can be set appropriately.

[0043] 3. Third embodiment A urinal device 1 of the third embodiment will be described with reference to the accompanying drawings. In the following description, the same components as those of the first embodiment will be given the same reference numerals and detailed description will be omitted.

[0044] As shown in FIG. 5, the aerial imaging device 4 provided in the urinal device 1 of the third embodiment includes a beam splitter 45 and a retroreflective sheet 46 instead of the optical plate 43 .

[0045] According to the aerial imaging device 4 described above, light emitted from the light source unit 41 enters the beam splitter 45, a part of which passes through the beam splitter 45, and another part is reflected and enters the retroreflective sheet 46. The light that enters the retroreflective sheet 46 is reflected toward the beam splitter 45. A part of the light reflected from the retroreflective sheet 46 toward the beam splitter 45 passes through the beam splitter 45.

[0046] In this way, the light emitted from light source unit 41 passes through beam splitter 45, then passes through part 215 of bowl portion 21 and exits, forming an image in the air away from bowl portion 21. The user can visually recognize this image as first target T1.

[0047] In the urinal device 1 of the third embodiment equipped with the above-mentioned aerial imaging device 4, too, the user can release urine so that it hits both the first target T1 and the second target T2, thereby effectively preventing urine from splashing back.

[0048] 4. Fourth embodiment A urinal device 1 of a fourth embodiment will be described with reference to the accompanying drawings. In the following description, the same components as those in the first embodiment will be given the same reference numerals and detailed description will be omitted.

[0049] As shown in Figure 6, the urinal device 1 of the fourth embodiment, instead of having a fixed target 71 as a means for constituting the second target T2, has an illumination unit 73 that emits light to illuminate a portion 217 of the bowl portion 21.

[0050] Part 217 of bowl portion 21 is located below part 215 of bowl portion 21. Part 217 of bowl portion 21 is located between part 215 of bowl portion 21 and drainage portion 23 of bowl portion 21.

[0051] The illumination unit 73 is disposed on the rear side of the bowl portion 21. In detail, the illumination unit 73 is disposed in a portion of the urinal 2 that is the rear side of the portion 217 of the bowl portion 21. The portion 217 of the bowl portion 21 is formed to be thinner than other portions of the bowl portion 21. The illumination unit 73 includes a light source, for example an LED, and is controlled by the control unit 6 to illuminate the rear surface of the portion 217 of the bowl portion 21 with light emitted by the light source.

[0052] In the urinal device 1 of the fourth embodiment, when a user approaches the urinal 2, the control unit 6 causes the illumination unit 73 to irradiate light toward the bowl portion 21, and illuminates a part 217 of the bowl portion 21, when the distance to the user detected by the detection unit 5 becomes equal to or less than a predetermined threshold. The illuminated part of the bowl portion 21 here functions as the second target T2.

[0053] When a user approaching the urinal 2 urinates toward the bowl portion 21, the control unit 6 detects that the user is urinating and also detects the user's physique based on the temperature distribution of the user detected by the detection unit 5. The control unit 6 controls the aerial imaging device 4 based on the detected physique, and selects the imaging position of the first target T1 so that it is a position suitable for that physique.

[0054] According to the urinal device 1 of the fourth embodiment, the user releases urine so that the urine hits both the first target T1 and the second target T2, thereby effectively preventing the urine from splashing back.

[0055] The irradiation unit 73 may be configured to be able to change the position where the second target T2 is illuminated in the part 217 of the bowl portion 21. In this case, the control unit 6 controls the aerial imaging device 4 and the irradiation unit 73 based on the physique detected by the detection unit 5, and can select the imaging positions of both the first target T1 and the second target T2 so that they are suitable for the physique. Specifically, when the user approaches the urinal 2, the control unit 6 illuminates the second target T2 in the part 217 of the bowl portion 21 when the distance between the user and the urinal 2 detected by the detection unit 5 becomes equal to or less than a predetermined threshold. When the user releases urine toward the bowl portion 21, the control unit 6 controls the irradiation unit 73 based on the physique detected by the detection unit 5, and changes or maintains the position of the second target T2 so that it is suitable for the physique.

[0056] 5. Fifth embodiment A urinal device 1 of a fifth embodiment will be described with reference to the accompanying drawings. In the following description, the same components as those of the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

[0057] 7, the urinal device 1 of the fifth embodiment includes a second aerial imaging device 8 that images the second target T2 in the air away from the bowl portion 21, instead of including a fixed target 71 as a means for configuring the second target T2. The second aerial imaging device 8 has a configuration similar to that of the aerial imaging device 4 for imaging the first target T1. In other words, the second aerial imaging device 8 includes a light source unit and optical plate similar to those of the aerial imaging device 4, but is not limited thereto, and can include, for example, a light source unit, a beam splitter, and a retroreflective sheet similar to those of the aerial imaging device 4 of the second embodiment.

[0058] A portion 219 of the bowl portion 21 (see FIGS. 7 and 8) is molded from a resin material having optical transparency, and the second aerial imaging device 8 is disposed on the rear side of the portion 219 of the bowl portion 21. The portions 215 and 219 of the bowl portion 21 are molded as one continuous piece vertically, but the portions 215 and 219 may be molded separately with a distance between them. In either case, it is possible to impart optical transparency to the portions 215 and 219 of the bowl portion 21 by molding the urinal 2 by two-color molding using a resin material that does not have optical transparency and a resin material that has optical transparency.

[0059] In the urinal device 1 of the fifth embodiment, when a user approaches the urinal 2, the control unit 6, when the distance to the user detected by the detection unit 5 falls below a predetermined threshold, irradiates light from the second aerial imaging device 8 to the outside through a part 219 of the bowl portion 21, and images a second target T2 in the air away from the bowl portion 21.

[0060] When a user approaches the urinal 2 and releases urine toward the second target T2, the control unit 6 controls the aerial imaging device 4 based on the physique detected by the detection unit 5, and images the first target T1 in the air away from the bowl portion 21 so that it is in a position suitable for that physique.

[0061] According to the urinal device 1 of the fifth embodiment, the user releases urine so that it hits both the first target T1 and the second target T2, both of which are imaged in the air, thereby effectively preventing the urine from splashing back.

[0062] The second aerial imaging device 8 may be configured to be able to change the imaging position of the second target T2. In this case, when the user approaches the urinal 2, the control unit 6 images the second target T2 when the distance between the user and the urinal 2 detected by the detection unit 5 becomes equal to or less than a predetermined threshold, and when the user urinates toward the second target T2, the control unit 6 controls the second aerial imaging device 8 based on the physique detected by the detection unit 5 to change or maintain the imaging position of the second target T2 to a position suitable for that physique.

[0063] 6. Variations Each of the above-described embodiments is merely one embodiment of the urinal device of the present disclosure, and design modifications can be made as appropriate within the scope that achieves similar effects, and the configurations of the above-described multiple embodiments can be combined as appropriate.

[0064] In the modifications listed below, the same components as those in the above-described embodiments are given the same reference numerals, and detailed descriptions thereof will be omitted.

[0065] In the urinal device 1 of each embodiment, the imaging position of the first target T1 by the aerial imaging device 4 is configured to be selectable, but this is not limited to this and the imaging position of the first target T1 by the aerial imaging device 4 may be fixed.

[0066] In the urinal device 1 of each embodiment, the first target T1 is imaged in the air after the user urinates, but it is also preferable to image the first target T1 in the air before the user urinates. In this case, for example, it is preferable to image the first target T1 when the distance from the user detected by the detection unit 5 becomes equal to or smaller than a predetermined threshold, and further, when the user urinates toward the bowl portion 21, it is preferable to change or maintain the image position of the first target T1 so that it is suitable for the physique detected by the detection unit 5.

[0067] In the urinal device 1 of the fifth embodiment, the aerial imaging device 4 for imaging the first target T1 and the second aerial imaging device 8 for imaging the second target T2 are separate devices, but this is not limited to the above, and it is also possible to use a common aerial imaging device 4 and the second aerial imaging device 8. In other words, it is also possible to image the first target T1 and the second target T2 using light irradiated from a single aerial imaging device. Furthermore, the mechanisms of the aerial imaging device 4 and the second aerial imaging device 8 are not limited to the above mechanisms, and any appropriate technology that can display targets in the air can be adopted.

[0068] In the urinal device 1 of the first to fifth embodiments, the urinal 2 is a wall-hung urinal, but is not limited to this and other types of urinals such as a floor-mounted urinal, a low-lip urinal, a cylindrical urinal, etc. can also be used.

[0069] 7. Summary As described above based on various embodiments and modifications, the urinal device (1) of the first aspect comprises a urinal (2) having a bowl portion (21), and a target forming means (3) that forms a first target (T1) and a second target (T2) positioned at a distance from each other as targets for urine discharged by a user toward the bowl portion (21). The target forming means (3) includes an aerial imaging device (4) configured to form an image of the first target (T1) in the air away from the bowl portion (21).

[0070] According to this aspect, by releasing urine so that the urine hits both the first target (T1) and the second target (T2), it is possible to effectively prevent the user's urine from splashing around the bowl portion (21). In other words, by configuring the first target (T1) and the second target (T2) as targets for urine, it is possible to guide the user to a standing position where the splashing of urine is effectively prevented, and to guide the angle at which the urine hits the bowl portion (21) to an angle at which the splashing of urine is effectively prevented.

[0071] In the urinal device (1) of the second embodiment, in the first embodiment, the second target (T2) is a target configured on the surface of the bowl portion (21).

[0072] According to this embodiment, the user can clearly identify the target on the surface of the bowl portion (21) against which the user should urinate, due to the presence of the second target (T2).

[0073] In the urinal device (1) of the third embodiment, in the second embodiment, the target forming means (3) includes a fixed target (71) fixed to the bowl portion (21) so as to form a second target (T2).

[0074] According to this embodiment, the second target (T2) can be configured with a simple structure in which the fixed target (71) is fixed to the surface of the bowl portion (21).

[0075] In the urinal device (1) of the fourth aspect, in the second aspect, the target formation means (3) includes an illumination section (73) that illuminates a part (219) of the bowl portion (21) to form a second target (T2).

[0076] According to this embodiment, since the second target (T2) can be illuminated on the surface of the bowl portion (21), the user can easily visually recognize the second target (T2).

[0079] In the sixth embodiment of the urinal device (1), in the first embodiment, the aerial imaging device (4) is installed on the back side of the bowl portion (21) and is configured to project light so as to pass through a portion (215) of the bowl portion (21) and image a first target (T1) in the air.

[0080] According to this embodiment, the presence of the first target (T1) enables the user to clearly recognize the target on which the user should urinate in the air away from the bowl portion (21). In addition, since the first target (T1) is formed by the formation of an optical image, the user can easily visually recognize the first target (T1).

[0081] In the urinal device (1) of the seventh aspect, in any one of the first to sixth aspects, the aerial imaging device (4) is configured to be able to select the position of the first target (T1).

[0082] According to this embodiment, by selecting the position of the first target (T1) according to conditions such as the physique of the user, it is possible to more effectively prevent the user's urine from splashing around the bowl portion (21). In other words, it is possible to more effectively guide the user to a standing position where splashing of urine is suppressed, and to more effectively guide the angle at which the urine hits the bowl portion (21) to an angle at which splashing of urine is suppressed.

[0083] The urinal device (1) of the eighth aspect is the urinal device (1) of the seventh aspect, further comprising a detection unit (5) that detects the body of a user. The aerial imaging device (4) is configured to be able to change the position of the first target (T1) based on the detection result of the detection unit (5).

[0084] According to this embodiment, by changing the position of the first target (T1) according to the physique of the user, it is possible to more effectively prevent urine from splashing around the bowl portion (21). In other words, it is possible to more effectively guide users of various body types to a standing position where urine splashing is suppressed, and to more effectively guide the angle at which urine hits the bowl portion (21) to an angle at which urine splashing is suppressed.
