[0056] 3. How to install a urinal Next, we will explain how to install the urinal 1 mentioned above.

[0057] The method for installing the urinal 1 includes a function unit fixing step S1, which involves fixing the urinal function unit 3 to the front side of the wall 10 of the toilet room, and a body mounting step S2, which involves detachably attaching the urinal body 2 to the front side of the wall 10 to which the urinal function unit 3 is fixed.

[0058] The main unit installation process S2 includes a first step S20 in which the urinal body 2 is detachably attached to the front side of the wall 10, a second step S21 in which the water supply unit 4 is detachably connected to the top of the urinal body 2, and a third step S22 in which the drain unit 5 is detachably connected to the drain hole 21. The second step S21 and the third step S22 are performed from the front side of the urinal body 2.

[0059] The functional unit fixing process S1 includes a frame fixing process S10 for fixing the frame 6 to the wall 10, a drainage unit fixing process S11 for fixing the drainage unit 5 to the wall 10, and a water supply unit fixing process S12 for fixing the water supply unit 4 to the wall 10. The functional unit fixing process S1 further includes a sensor fixing process S13 for fixing the motion sensor 7 to the wall 10.

[0060] In the frame fixing process S10, the upper horizontal frame 61 and the lower horizontal frame 62 of the frame 6 are fixed to the wall 10 with fasteners such as screws. The pair of vertical frames 60 are indirectly fixed to the wall 10 by fixing the upper horizontal frame 61 and the lower horizontal frame 62 to the wall 10.

[0061] In the drain unit fixing process S11, the wall fixing part 52 of the drain unit 5 is fixed to the wall 10 with fasteners such as screws, the connecting pipe 53 is connected to the wall fixing part 52, and the straight pipe part 501 of the drain trap part 50 is connected to the connecting pipe 53 via the joint part 54.

[0062] The drainage unit fixing step S11 may be performed after the frame fixing step S10 or before the frame fixing step S10. If the drainage unit fixing step S11 is performed after the frame fixing step S10, the wall fixing part 52 is fixed to the wall 10 so that the wall fixing part 52 is supported by the drainage unit support part 65 of the lower horizontal frame 62. If the drainage unit fixing step S11 is performed before the frame fixing step S10, the frame 6 is fixed to the wall 10 so that the wall fixing part 52 is supported from below by the drainage unit support part 65 of the lower horizontal frame 62.

[0063] The water supply unit fixing process S12 is performed after the frame fixing process S10. In the water supply unit fixing process S12, the pump 41 is placed on the support part 63 attached to the frame 6, and the control unit 43 is installed inside the support part 64, thereby indirectly fixing the water supply unit 4 to the wall 10. The hose 42 and the water discharge part 40 are movable. The control unit 43 may be attached to the support part 64 in advance (i.e., at a factory, etc.).

[0064] In the water supply unit fixing process S12, the pump 41 is connected to the water supply pipe that has been pulled out from the wall 10 to the front. Then, the pump 41 and the control unit 43 are connected to the electrical wiring that has been pulled out from the wall 10.

[0065] The sensor fixing process S13 is performed after the frame fixing process S10. In the sensor fixing process S13, the motion sensor 7 is indirectly fixed to the wall 10 by attaching it to the support part 64. In the sensor fixing process S13, the motion sensor 7 is connected to the electrical wiring that is pulled out from the wall 10. The motion sensor 7 may be attached to the support part 64 in advance (i.e., at the factory, etc.).

[0066] After the functional unit fixing process S1, the main body mounting process S2 is performed.

[0067] In the first step S20 of the main unit installation process S2, the urinal body 2 is installed on the front side of the wall 10. In the first step S20, the water outlet 40 of the water supply unit 4 is first passed through the connection hole 200 of the bowl portion 20 of the urinal body 2. At this time, the connector 8 is not attached to the water outlet 40.

[0068] Next, as shown in Figure 5, the urinal body 2 is installed such that the bottom plate portion 211 of the drain hole 21 of the urinal body 2 rests on the bottom plate portion 5020 of the drain hole receiving portion 502 of the drain unit 5, and the pair of mounting portions 220 of the urinal body 2 rest on the pair of mounting portions 610 of the upper horizontal frame 61 of the frame 6. At this time, the pair of side wall portions 22 of the urinal body 2 are aligned with the left and right outer surfaces of the pair of vertical frames 60 of the frame 6, and the pair of side wall portions 22 are in contact with the left and right pair of contact surfaces 620 of the lower horizontal frame 62. Then, the toilet receiving portion 51 of the drain unit 5 is in contact with the front wall portion 23 of the urinal body 2.

[0069] Next, the pair of mounting parts 220 of the urinal body 2 are fixed to the pair of mounting parts 610 of the frame 6 with fasteners such as screws. Then, the top cover part 25 is attached to the pair of mounting parts 220, covering the internal space R1 of the urinal body 2 and the urinal function unit 3 with the top cover part 25.

[0070] The second step S21 is performed after the first step S20. In the second step S21, the water supply unit 4 is detachably connected to the upper part of the urinal body 2. In the second step S21, first, the connector 8 is attached around the water outlet 40 which has been pulled forward from the connection hole 200 of the urinal body 2, and the connector 8 and the water outlet 40 are inserted into the connection hole 200 by grasping the pair of handles 82 of the connector 8. At this time, the pair of handles 82 are inserted into the notch 200b of the connection hole 200, and the pair of clamping pieces 80, connecting piece 81 and water outlet 40 are inserted into the circular part 200a of the connection hole 200. Next, the hands are released from the pair of handles 82 that have been inserted into the notch 200b. Then, the pair of handles 82 move away from each other and catch on the edge of the hole in the notch 200b. As a result, the water outlet 40 is connected to the connection hole 200. Here, the connector 8 can be removed from the connection hole 200 together with the water outlet 40 by pinching the pair of knobs 82. Therefore, in the second step S21, the water outlet 40 is detachably connected to the connection hole 200.

[0071] The third step S22 is performed after the first step S20. The third step S22 may be performed either before or after the second step S21.

[0072] In the third step S22, the drain unit 5 is detachably connected to the drain hole 21. First, in the third step S22, the connector 9 is inserted from the front of the urinal body 2 into the drain hole 21, which is resting on the drain hole receiving portion 502 of the drain unit 5. At this time, the cylindrical portion 91 of the connector 9 is fitted into the curved pipe portion 500 of the drain trap portion 50, and the bottom plate portion 211 of the drain hole 21 is pressed against the bottom plate portion 5020 of the drain hole receiving portion 502 of the drain trap portion 50 by the retaining portion 90. As a result, the drain hole 21 is connected to the drain trap portion 50. Here, the connector 9 can be removed from the drain hole 21 by operation from the front of the urinal body 2. Therefore, in the third step S22, the drain unit 5 is detachably connected to the drain hole 21.

[0073] As described above, by performing the functional unit fixing process S1 and the main body mounting process S2, the urinal 1 can be installed on the wall 10 as shown in Figure 5.

[0074] 4. How to replace a urinal Next, we will explain how to replace urinal 1.

[0075] The method for replacing the urinal 1 includes a first connection release step S3, which releases the connection between the connection hole 200 of the urinal body 2 and the water discharge part 40 of the water supply unit 4, and a second connection release step S4, which releases the connection between the drain hole 21 and the drain unit 5. The method for replacing the urinal 1 further includes a body removal step S5, which removes the urinal body 2 from the frame 6, and the body installation step S2 described above.

[0076] In the first disconnection step S3, first, the pair of tabs 82 of the connector 8 located in the notch 200b of the connection hole 200 of the bowl portion 20 are grasped, and the connector 8 and the water outlet portion 40 are pulled forward from the connection hole 200. Next, the connector 8 is removed from the water outlet portion 40. Then, the water outlet portion 40 is inserted into the connection hole 200, and the water outlet portion 40 is positioned in the internal space R1 of the urinal body 2. This releases the water outlet portion 40 from its connection to the connection hole 200.

[0077] The second disconnection step S4 is performed after the first disconnection step S3, or before the first disconnection step S3. In the second disconnection step S4, the connector 8 is pulled out of the drain hole 21 by operation from the front of the urinal body 2. This releases the drain hole 21 from being connected to the drain trap section 50.

[0078] The main body removal process S5 is performed after the first connection disconnection process S3 and the second connection disconnection process S4. In the main body removal process S5, first, the top cover 25 is removed and the fasteners such as screws that secure the pair of mounting parts 220 and the pair of mounting parts 610 are removed. Next, the urinal body 2 is lifted diagonally upward and forward to separate the urinal body 2 from the pair of mounting parts 610. This removes the urinal body 2 from the frame 6.

[0079] After the main unit removal process S5, the main unit installation process S2 described above is performed using the new urinal main unit 2.

[0080] As described above, by performing the first disconnection step S3, the second disconnection step S4, the main unit removal step S5, and the main unit installation step S2, the existing urinal main unit 2 can be replaced with a new urinal main unit 2. This allows for the replacement of the urinal 1.

[0081] 5. Effects In the urinal 1 of this embodiment described above, the urinal function unit 3 (water supply unit 4, drainage unit 5, frame 6, and motion sensor 7) is fixed directly or indirectly to the wall 10. The urinal body 2 is detachably attached to the wall 10 and the urinal function unit 3.

[0082] Therefore, in the urinal 1 of this embodiment, when replacing it with a new urinal 1, the urinal function unit 3 can be left on the wall 10, and only the urinal body 2 can be replaced. This makes it easier to replace the urinal 1 of this embodiment with a new urinal 1.

[0083] Furthermore, in the urinal 1 of this embodiment, the urinal body 2 is made of thin resin molded material with a wall thickness of 0.6 to 6 mm, so the urinal body 2 is lightweight and easy to transport and replace.

[0084] Furthermore, in the urinal 1 of this embodiment, although the urinal body 2 is thin, the frame 6 and the toilet bowl receiving portion 51 of the drain unit 5 come into contact with the urinal body 2 from the inside, thus reinforcing the thin urinal body 2. Therefore, in the urinal 1 of this embodiment, it is easy to ensure strength even with a thin urinal body 2.

[0085] Furthermore, in the urinal 1 of this embodiment, since the urinal body 2 is thin, the amount of resin required to mold the urinal body 2 can be reduced, making it easier to reduce the manufacturing cost of the urinal body 2.

[0086] Furthermore, in the urinal 1 of this embodiment, the drain unit 5 fixed to the wall 10 includes a drain trap section 50, while the urinal body 2 does not include a drain trap section 50. This simplifies the structure of the urinal body 2 and reduces its weight. In this respect as well, the manufacturing cost of the urinal body 2 can be easily reduced in the urinal 1 of this embodiment.

[0087] Furthermore, in the urinal 1 of this embodiment, the water supply unit 4, the drainage unit 5, and the motion sensor 7 are mounted on the frame 6, so the relative positions of the water supply unit 4, the drainage unit 5, the motion sensor 7, and the frame 6 tend to remain constant. Therefore, in the urinal 1 of this embodiment, when replacing the urinal body 2 with a new urinal body 2 of the same shape, it is easy to install the water supply unit 4, the drainage unit 5, the motion sensor 7, and the frame 6 in an appropriate position inside the new urinal body 2.

[0088] Furthermore, in the urinal 1 of this embodiment, the connector 8 that connects the connection hole 200 of the urinal body 2 to the water outlet 40 of the water supply unit 4 can be attached and detached from the front of the urinal body 2. Also, in the urinal 1 of this embodiment, the connector 9 that connects the drain hole 21 of the urinal body 2 to the drain trap section 50 of the drain unit 5 can be attached and detached from the front of the urinal body 2. Therefore, in the urinal 1 of this embodiment, the attachment and detachment of the urinal body 2 to the water supply unit 4 and the attachment and detachment of the urinal body 2 to the drain unit 5 can be easily performed. The connectors 8 and 9 can also be reused even when the urinal body 2 is replaced with a new urinal body 2.

[0089] Furthermore, in the urinal 1 of this embodiment, the urinal function unit 3 is housed in the space between the urinal body 2 and the wall 10 (i.e., the internal space R1 of the urinal body 2), so it can have the same appearance as a typical urinal in which the urinal function unit 3 is built into the urinal body 2.

[0090] (modified version) Next, we will describe some modifications of the urinal 1 and the method of installing the urinal 1 according to the above-described embodiment. Note that the following modifications can be combined as appropriate.

[0091] The urinal function unit 3 does not necessarily have a pair of vertical frames 60. In this case, it is preferable that the urinal body 2 be made thick enough so that the pair of side walls 22 of the urinal body 2 do not bulge outwards.

[0092] Furthermore, the urinal function unit 3 does not need to have either the upper horizontal frame 61 or the lower horizontal frame 62, or both. In this case, the water supply unit 4 and the drainage unit 5 may each be directly fixed to the wall 10.

[0093] The water supply unit 4 does not necessarily have to be attached to the upper horizontal frame 61; it may be directly fixed to the wall 10.

[0094] The drainage unit 5 does not necessarily have to be attached to the lower horizontal frame 62, and may be fixed only to the wall 10.

[0095] The pair of vertical frames 60, the upper horizontal frame 61, and the lower horizontal frame 62 do not have to be provided as a single unit, but may be provided as separate components.

[0096] The drain unit 5 does not necessarily have to include a drain trap section 50, and the drain trap section 50 may be provided integrally with the drain hole 21 of the urinal body 2.

[0097] The urinal function unit 3 does not need to be fixed to the wall 10 so that it fits into the space (internal space R1) between the pair of side walls 22 of the urinal body 2, or it may be fixed to the wall 10 so that a part of the urinal function unit 3 is located outside the urinal body 2 and exposed.

[0098] The urinal function unit 3 may be fixed to the front of the wall 10 such that a portion of the urinal function unit 3 is located behind the wall 10.

[0099] The urinal function unit 3 does not need to have a motion sensor 7. The motion sensor 7 may be attached to the urinal body 2.

[0100] The urinal body 2 does not have to be a resin molded product formed by injection molding. The urinal body 2 may be a resin molded product formed by a method other than injection molding, for example, by blow molding.

[0101] The walls that make up the urinal body 2 do not have to be 0.5 to 6 mm thick, and may be thicker than 6 mm.

[0102] The urinal body 2 is not limited to being made of resin; it may also be made of metal. Furthermore, the urinal body 2 may be formed from other materials such as ceramics.

[0103] The second step S21, in which the water supply unit 4 is detachably connected to the urinal body 2, and the third step S22, in which the drain unit 5 is detachably connected to the drain hole 21, do not necessarily have to be performed from the front of the urinal body 2. The second step S21 and the third step S22 may also be performed between the urinal body 2 and the wall 10, with the urinal body 2 separated from the wall 10 in the front.

[0104] The pair of vertical frames 60 may be positioned so as to contact the inner surfaces of the pair of side wall portions 22 of the urinal body 2.

[0105] Wall 10 may be a front panel of a lining installed on the front side of one of the walls surrounding the interior space of the toilet room. The lining comprises at least a frame, a front panel attached to the front side of the frame, and a top panel attached to the top side of the frame.
