The toilet body 2 of this embodiment is made of synthetic resin, and is integrally formed by, for example, injection molding or cast molding. The toilet body 2 includes a bowl portion 20 and an outer shell portion 21. The bowl portion 20 is a portion that receives the urine of a user standing in front of the toilet body 2. The outer shell portion 21 is a portion that forms the outer shell of the toilet body 2.

The bowl portion 20 has a rear portion 24 that protrudes upward more than a front portion 23. In the present embodiment, the inner surface of the bowl portion 20 is a urine receiving surface 22 that receives urine. The urine receiving surface 22 is composed of the inner surface of the rear portion 24 of the bowl portion 20 and the inner surface of the front portion 23 of the bowl portion 20.

The inner surface of the rear portion 24 of the bowl portion 20 includes a facing surface 25 facing the user, and left and right side surfaces 26 and 27 extending forward from both left and right ends of the facing surface 25.

As shown in FIG. 2, a drain port 28 is formed at the lower end of the bowl portion 20. The cleaning water supplied from the cleaning water supply device 3 to the bowl portion 20 is discharged from the drain port 28 to the drain pipe 92 provided on the floor 91.

(Cleaning water supply device 3)
The flush water supply device 3 includes a water discharger 30 provided in the bowl 20, a water supply passage 31 that supplies water to the water discharger 30, and an opening/closing valve 32 provided in the water supply passage 31.

The water discharger 30 is located at the upper end of the facing surface 25 of the urine receiving surface 22. The water discharger 30 is connected to a water supply source via a water supply passage 31. The water supply channel 31 is composed of, for example, a pipe, and the water supply source is composed of, for example, a water pipe.

The water discharger 30 discharges the water supplied from the water supply passage 31 into the bowl 20 as cleaning water and causes the cleaning water to flow down to the urine receiving surface 22. The water discharger 30 of this embodiment is a spreader having a plurality of discharge ports 33. As shown in FIG. 3, the water discharger 30 radially discharges the water supplied from the water supply source from the plurality of discharge ports 33 toward the lower side.

An on-off valve 32 for switching the presence/absence of water supply from the water supply source to the water discharger 30 is provided in the middle of the water supply passage 31. The open/close valve 32 is, for example, a solenoid valve.

(Detection unit 4 and control unit 5)
As shown in FIG. 4, the urinal 1 further includes a detection unit 4 and a control unit 5. The detection unit 4 detects whether or not a human body exists in front of the toilet body 2 (see FIG. 2). The control unit 5 controls the open/close valve 32 based on the detection result of the detection unit 4.

The detection unit 4 is, for example, an infrared sensor. The detector 4 is provided at the upper end of the facing surface 25 of the bowl 20 as shown in FIG. 3, for example.

The control unit 5 shown in FIG. 4 is composed of, for example, a microcomputer. The controller 5 is electrically connected to the open/close valve 32 and the detector 4.

The detection unit 4 outputs the detection information to the control unit 5. The control unit 5 controls the opening/closing valve 32 as follows based on the detection information input from the detection unit 4.

The control unit 5 detects the presence of a human body in front of the toilet body 2 by the detection unit 4, and then detects the presence of a human body in front of the toilet body 2 by the detection unit 4 and then opens and closes the open/close valve 32. open. As a result, water is supplied from the water supply passage 31 shown in FIG. 2 to the water discharge part 30, and the wash water is discharged from the water discharge part 30 to the urine receiving surface 22.

The control unit 5 shown in FIG. 4 closes the opening/closing valve 32 when a predetermined time has elapsed after opening the opening/closing valve 32 as described above. As a result, the discharge of cleaning water from the water discharger 30 is stopped.

According to the above-mentioned control, when the user stands in front of the toilet body 2 and wears the urinal 1 and then leaves from the front of the toilet body 2, flush water is automatically discharged from the water discharge unit 30 for a predetermined time. Then, the urine receiving surface 22 is washed with this washing water.

(Projection 6)
As shown in FIG. 2, the urinal 1 further includes a protrusion 6 provided on the urine receiving surface 22. The protruding portion 6 suppresses the urine that hits the urine receiving surface 22 and bounces back from the toilet body 2.

The projecting portion 6 of the present embodiment is provided on the urine receiving surface 22 below the facing surface 25, which is the location where the user applies the most urine. The protrusion 6 is located below the plurality of discharge ports 33 of the water discharger 30.

The protruding portion 6 can be switched between a first state shown in FIG. 5A in which it protrudes from the facing surface 25 and a second state shown in FIG. 5B in which the tip is closer to the facing surface 25 than in the first state.

The protrusion 6 of this embodiment is composed of a plurality of protrusions 60. The plurality of protrusions 60 protrude from the front surface of the base portion 61 provided in the toilet body 2 as shown in FIG. The base portion 61 has a plate shape, and is provided inside the rear wall portion of the bowl portion 20 by insert molding, for example.

Each of the plurality of protrusions 60 is linear and protrudes from the facing surface 25. The plurality of protrusions 60 are deformable and can be raised and lowered with respect to the facing surface 25. Here, “it can be tilted” means that the plurality of protrusions 60 can be deformed between a state in which they are projected from the facing surface 25 and erected with respect to the facing surface 25, and a state in which they are tilted along the facing surface 25. means.

When in the first state shown in FIG. 5A, the plurality of protrusions 60 protrude forward and obliquely downward from the facing surface 25. When in the second state shown in FIG. 5B, the plurality of protrusions 60 are tilted so as to face further downward than in the first state, and the tips are closer to the facing surface 25 than in the first state.

The plurality of protrusions 60 of the present embodiment is a ferromagnetic shape memory alloy. The ferromagnetic shape memory alloy is a shape memory alloy that returns to its original shape by applying a magnetic field even if the shape is changed.

Each protrusion 60 remembers the shape of the first state shown in FIG. 5A. That is, each of the protrusions 60 is arranged in the magnetic field to be deformed into the shape of the first state by the shape memory effect.

(Drive unit 7)
As shown in FIG. 2, the urinal 1 of the present embodiment further includes a drive unit 7 that drives the protrusion 6. The drive unit 7 is provided, for example, behind the bowl unit 20.

The drive unit 7 of this embodiment has an electromagnet 70 that generates a magnetic field in the region where the protrusion 6 is present. When the electromagnet 70 is energized, the magnetic field generated by the electromagnet 70 is loaded on the protrusion 6, and the protrusion 6 is deformed to the first state.

The drive unit 7 is electrically connected to the control unit 5 shown in FIG. The control unit 5 controls the drive unit 7 based on the detection information input from the detection unit 4, for example, as follows.

When the detection unit 4 detects the presence of a human body in front of the toilet body 2, the control unit 5 starts energizing the electromagnet 70. As a result, the protrusion 6 is transformed into the first state by the magnetic field generated by the electromagnet 70.

After the start of energization of the electromagnet 70, the control unit 5 stops energization of the electromagnet 70 when the detection unit 4 detects that there is no human body in front of the toilet body 2. As a result, the projecting portion 6 is in a state where no magnetic field is applied and can be deformed. The control for stopping the energization of the electromagnet 70 is performed at the same time as the control for opening the on-off valve 32 described above.

According to the above-mentioned control, when the user stands in front of the toilet body 2 when adding the urinal 1, the plurality of protrusions 60 have the shape of the first state protruding from the urine receiving surface 22 as shown in FIG. 5A. Deform. For this reason, even if the user uses the urinal 1 to relieve the urine that hits the urine receiving surface 22, the urine adheres to the plurality of protrusions 60 as shown by the arrows in FIG. 5A. Therefore, it is difficult for the urine to scatter out of the bowl portion 20.

Further, when the user leaves the front of the body 2 of the toilet after applying the urinal 1, the energization of the electromagnet 70 is stopped and the protrusion 6 becomes deformable. Therefore, the plurality of protrusions 60 are deformed into the shape of the second state shown in FIG. 5B by the wash water discharged from the water discharger 30 and flowing down the urine receiving surface 22 and the weight of the plurality of protrusions 60. Therefore, the flow of the wash water flowing through the urine receiving surface 22 is less likely to be blocked by the protrusion 6, and the wash water can easily flow smoothly. Further, at this time, since the plurality of protrusions 60 are in a state of falling along the urine receiving surface 22, it is difficult to disturb the urine receiving surface 22 during cleaning.

Note that the plurality of protrusions 60 may be configured to be deformed from the first state to the second state only by their own weight when the energization of the electromagnet 70 is stopped.

In the present embodiment, the energization of the electromagnet 70 is stopped at the same time as the opening/closing valve 32 is opened, but the energization of the electromagnet 70 may be stopped before the wash water flows through the urine receiving surface 22. For example, after the energization of the electromagnet 70 is started, the energization of the electromagnet 70 is stopped after a predetermined time, and at the same time as the energization is stopped or after the energization is stopped, a human body exists in front of the toilet body 2 by the detection unit 4. The on-off valve 32 may be opened when it is detected that it is not.

The power source of the urinal 1 may be a commercial power source or a generator. The power supply of the urinal 1 may be composed of a commercial power supply and a generator. As the generator, for example, the power generation floor device 8 shown in FIG. 2 is used.

The power generation floor device 8 is installed, for example, on the floor 91 in front of the toilet body 2. The power generation floor device 8 includes a piezoelectric element that converts pressure energy into electric energy, and when the weight of the user is added to this piezoelectric element, electric power is generated.

The generator is not limited to the power generation floor device 8, and may be a solar power generation device, a hydraulic power generation device that uses the flow of water flowing through the water supply channel 31, or the like to generate electric power.

Further, although the plurality of protrusions 60 of the present embodiment are ferromagnetic shape memory alloys, they may be shape memory alloys that deform to the first state by heating. In this case, the drive unit 7 is composed of, for example, a heater that heats the plurality of protrusions 60. When the plurality of protrusions 60 are made of a shape memory alloy that stores the first state, it is possible to deform the plurality of protrusions 60 into the first state by heating with urine. In this case, the drive unit 7 can be omitted.

(Modification)
Next, modifications 1 to 3 will be described. In the following description of Modifications 1 to 3, the same components as those of the above-described embodiment are designated by the same reference numerals, and the description of common points is omitted.

(Modification 1)
In the urinal 1 of the modified example 1 shown in FIGS. 6A and 6B, each of the plurality of protrusions 60 is a plate-shaped movable piece. Each protrusion 60 is a ferromagnetic shape memory alloy, similar to the protrusion 60 in the above-described embodiment. When in the first state shown in FIG. 6A, the plurality of protrusions 60 project from the facing surface 25 toward the front obliquely downward direction. When in the second state shown in FIG. 6B, the plurality of protrusions 60 fall so as to face further downward than in the first state, and the tips thereof are closer to the facing surface 25 than in the first state. Each protrusion 60 remembers the shape of the first state shown in FIG. 6A.

(Modification 2)
(Projection 6)
In the urinal 1 of the modification 2 shown in FIG. 7, the protrusion 6 is formed of a mesh member. The protrusion 6 is formed of, for example, a synthetic resin material or a metal material, and is formed in a net shape as a whole. Liquids such as wash water and urine can pass through the mesh of the protrusion 6.

The projecting portion 6 is formed in a cylindrical shape that is circular in a front view and opens rearward. As shown in FIG. 8, the projecting portion 6 includes a front surface portion 62 and a peripheral surface portion 63 that extends rearward from the peripheral edge of the front surface portion 62.

At the rear end of the protrusion 6, a member 64 that covers the rear surface of the protrusion 6 (the surface that faces the inner side of the recess 29 described later) is provided. In this modification, the base portion 61 is not provided.

The member 64 is formed in a plate shape whose thickness direction is parallel to the front-back direction. The member 64 closes the rear end opening of the protrusion 6.

The urine receiving surface 22 of the toilet body 2 is formed with a recess 29 for accommodating the protrusion 6 together with the member 64. The concave portion 29 is located below the facing surface 25 and opens toward the front. The recess 29 has substantially the same shape and size as the protrusion 6 in a front view.

The projecting portion 6 is housed together with the member 64 in the recess 29 so as to be able to enter and leave. The protrusion 6 moves in the front-rear direction together with the member 64 (displacement) to thereby protrude forward from the facing surface 25, that is, the first state shown in FIG. 9A and the second state shown in FIG. It can be switched to.

(Drive unit 7)
The drive unit 7 has a motor and can drive the protrusion 6 together with the member 64 in the front-rear direction by energization. The drive unit 7 is controlled by the control unit 5 as follows.

When the detection unit 4 detects the presence of a human body in front of the toilet body 2, the control unit 5 controls the drive unit 7 so that the protrusion 6 drives forward together with the member 64. As a result, the protruding portion 6 is in the first state in which the protruding portion 6 protrudes forward from the facing surface 25, as shown in FIG. 9A. In the first state, the front surface of the member 64 is flush with the facing surface 25, and the front end opening of the recess 29 is closed by the member 64.

As described above, the control unit 5 detects the presence of a human body in front of the toilet body 2 by the detection unit 4 and then detects the presence of a human body in front of the toilet body 2 by the detection unit 4 and then projects. The drive unit 7 is controlled so that the unit 6 and the member 64 are driven backward. As a result, the protrusion 6 is in the second state where it is housed in the recess 29 as shown in FIG. 9B.

By the control described above, when the user stands in front of the toilet body 2, the drive unit 7 drives the protrusion 6 to the position in the first state shown in FIG. 9A. Therefore, even if the user makes a use of the urinal 1 and the urine that hits the urine receiving surface 22 or the front surface of the member 64 bounces off, the urine adheres to the protrusion 6 and is exposed to the outside of the urinal body 2. Difficult to scatter. Further, at this time, since the front end opening of the recess 29 is closed by the member 64, it is difficult for urine to enter the recess 29, and the recess 29 is unlikely to become dirty.

In addition, when the user leaves the front of the toilet body 2 after using the urinal 1, the drive unit 7 drives the protrusion 6 to the position of the second state shown in FIG. 9B. For this reason, the flow of the wash water flowing through the urine receiving surface 22 is less likely to be blocked by the protrusion 6, and the wash water can easily flow smoothly. Further, at this time, since the projecting portion 6 does not project further forward than the facing surface 25, it is unlikely to be an obstacle when cleaning the urine receiving surface 22.

(Modification 3)
The protruding portion 6 of the urinal 1 of the modified example 3 shown in FIGS. 10A and 10B is composed of a plurality of protruding pieces 65. Each projecting piece 65 has a horizontal plate shape and projects forward from the base portion 61.

The base portion 61 is arranged, for example, behind the rear wall portion of the bowl portion 20. The base portion 61 is provided so as to be movable back and forth with respect to the toilet body 2 together with the plurality of protrusions 65.

As the base portion 61 moves back and forth, the plurality of projecting pieces 65 face the first state in which the plurality of projecting pieces 65 project forward from the facing surface 25 as shown in FIG. It is possible to switch to the second state in which the surface 25 does not project.

The drive unit 7 has a motor and can drive the mesh member and the cover member in the front-back direction by energization. The drive unit 7 is controlled by the control unit 5 as follows.

When the detection unit 4 detects the presence of a human body in front of the toilet body 2, the control unit 5 controls the drive unit 7 so as to drive the plurality of protrusions 65 together with the base unit 61 forward. As a result, the plurality of projecting pieces 65 are in the first state in which they are projected forward from the facing surface 25 as shown in FIG. 10A.

As described above, the control unit 5 detects the presence of the human body in front of the toilet body 2 by the detection unit 4 and then detects the absence of the human body in front of the toilet body 2 by the detection unit 4 as a base. The drive unit 7 is controlled so as to drive the plurality of protrusions 65 together with the unit 61 rearward. As a result, the plurality of projecting pieces 65 are in the second state in which they do not project from the facing surface 25, as shown in FIG. 10B.

By the control described above, when the user stands in front of the toilet body 2, the drive unit 7 drives the plurality of protrusions 65 to the position of the first state shown in FIG. 10A. Therefore, even if the user uses the urinal 1 to relieve the urine that hits the facing surface 25, the urine adheres to the plurality of protrusions 65 and is less likely to scatter to the outside of the urinal body 2. ..

Further, when the user leaves the urinal body 2 from the front side after using the urinal 1, the drive unit 7 drives the plurality of projecting pieces 65 to the position of the second state shown in FIG. 10B. For this reason, the flow of the wash water flowing through the urine receiving surface 22 is less likely to be blocked by the plurality of protrusions 65, and the wash water can easily flow smoothly. In addition, at this time, since the plurality of projecting pieces 65 do not project further forward than the facing surface 25, they are unlikely to be an obstacle when cleaning the urine receiving surface 22.

(effect)
The urinals 1 of the embodiment and each modification described above have the following configurations. The urinal 1 includes a urinal body 2 having a urine receiving surface 22 and a protrusion 6 provided on the urine receiving surface 22. The protruding portion 6 can be switched between a first state in which the protruding portion 6 protrudes from the urine-receiving surface 22 and a second state in which the tip is closer to the urine-receiving surface 22 than in the first state. When the human body is present in front of the toilet body 2, the protrusion 6 is configured to move from the second state to the first state.

The urinal 1 having this configuration is switched to the first state in which the protrusion 6 protrudes from the urine receiving surface 22 when a human body is present in front of the toilet body 2. For this reason, even if the user uses the urinal 1 to relieve the urine that hits the urine receiving surface 22, the urine adheres to the protrusion 6. Therefore, the urine is less likely to be scattered outside the toilet body 2. Further, when cleaning the urine receiving surface 22, the protruding portion 6 can be switched to the second state in which the tip end is closer to the urine receiving surface 22 than in the first state. Therefore, the flow of the wash water flowing through the urine receiving surface 22 is less likely to be blocked by the protrusion 6, and the wash water can easily flow smoothly.

Moreover, the urinal 1 of the above-described embodiment and each modified example has the following additional configuration. The urinal 1 includes a drive unit 7, a detection unit 4, and a control unit 5. The drive unit 7 drives the protrusion 6 to switch from the second state to the first state. The detection unit 4 detects whether or not a human body exists in front of the toilet body 2. The control unit 5 controls the drive unit 7 so that the protrusion 6 switches from the second state to the first state when the detection unit 4 detects the presence of a human body in front of the toilet body 2.

In the urinal 1 having this configuration, when the detection unit 4 detects the presence of a human body in front of the toilet body 2, the protrusion 6 is switched to the first state by the drive unit 7. Therefore, when the user uses the urinal 1 for supplementation, the protrusion 6 is automatically switched to the first state.

In addition, the urinal 1 of the above-described embodiment and modification 1 has the following additional configuration. The protrusion 6 is formed of a ferromagnetic shape memory alloy. The driving unit 7 generates a magnetic field so that the protrusion 6 is deformed from the second state to the first state.

In the urinal 1 having this configuration, the protrusion 6 can be driven by using the drive unit 7 that generates a magnetic field.

In addition, the urinal 1 of the above-described embodiment and modification 1 has the following additional configuration. The protrusion 6 is composed of a plurality of protrusions 60 protruding from the urine receiving surface 22. The first state is a state in which the plurality of protrusions 60 stand upright with respect to the urine receiving surface 22. The second state is a state in which the plurality of protrusions 60 are along the urine receiving surface 22.

In the urinal 1 having this characteristic, scattering of urine is suppressed by the plurality of protrusions 60 standing upright on the urinal 1 receiving surface.

Moreover, the urinal 1 of the modification 2 has the following additional configurations. A recess 29 is formed in the urine receiving surface 22. The protrusion 6 is composed of a mesh member that is housed in the recess 29 so as to be able to enter and exit. The first state is a state in which the protrusion 6 protrudes from the recess 29. The second state is a state in which the protrusion 6 is housed in the recess 29.

In the urinal 1 having this configuration, the protrusion 6 made of a mesh member suppresses the scattering of urine. Moreover, since the protrusion 6 in the second state is housed in the recess 29, it is unlikely to be an obstacle when cleaning the urine receiving surface 22.

Moreover, the urinal 1 of the modification 2 has the following additional configurations. The protruding portion 6 is provided with a member 64 that covers the surface of the protruding portion 6 that faces the inner side of the recess 29.

In the urinal 1 having this structure, the urine that has passed through the mesh of the protrusion 6 is received by the member 64, and it is difficult for the urine to enter the recess 29. Therefore, the recess 29 is less likely to get dirty.

(application)
In the urinal 1 of the above-described embodiment and each modified example, the projecting portion 6 is provided on the facing surface 25 of the toilet body 2 facing the user, but the projecting portion 6 includes the side surfaces 26, 27 and It may be provided on the other urine receiving surface 22, such as the inner surface of the front portion 23 of the bowl portion 20.

Further, the urinal 1 of the above-described embodiment and each modification is a floor-standing urinal 1, but may be a wall-mounted urinal 1 or a so-called sanitary stand.

Further, the configurations described in the above-described embodiment and each modified example can be appropriately combined and applied.

In addition to this, the design of the urinal 1 of the above-described embodiment and each modified example can be appropriately changed.
