Waste sink unit 19 is provided to the side of urinal 18, and is a device for ostomates to dispose of waste such as feces.

[0030] Next, the lining unit 20 protruding from the wall surface of the toilet room TR will be described. FIG. 2 is a front view of the first portion and the second portion of the first lining. FIG. 3 is a perspective view showing the state in which the auxiliary stand is attached between the first portion and the toilet bowl.

[0031] In the toilet room TR, a lining unit 20 is provided on the wall side facing the entrance 1. The lining unit 20 may also be called a cabinet or a casing. The lining unit 20 is installed on the floor surface F and the wall surface W of the toilet room TR.

[0032] The lining unit 20 has a first lining 21 disposed to the side of the toilet bowl 12, and a second lining 25 located behind the toilet bowl 12. The lining unit 20 is formed into an L-shape by the first lining 21 and the second lining 25 when viewed from above (plan view). The first lining 21 and the second lining 25 are formed into a rectangular shape when viewed from the front. In the explanation of the first lining 21 and the washbasin 50 provided on the first lining 21, the side of the wall surface W to which the first lining 21 is attached will be described as the "rear", and the opposite side will be described as the "front". In addition, the right side as viewed from the user using the washbasin 50 will be described as the "right" and the left side as the "left".

[0033] The first lining 21 is provided with equipment such as a hand washing basin 16, an operation remote control 34, a paper roll holder 38, and a washbasin 50. The second lining 25 is provided with equipment such as a toilet bowl 12, a backrest 15, a baby chair 17, a urinal 18, and a waste sink unit 19. Inside the lining unit 20, pipes, electrical equipment, etc. are housed.

[0034] The first lining 21 has a first portion 22 located to the side of the toilet bowl 12, and a second portion 23 adjacent to the first portion 22. The second portion 23 is disposed at a position farther away from the toilet bowl 12 than the first portion 22. In other words, the second portion 23 extends from the first portion 22 in the opposite direction to the toilet bowl 12. The second portion 23 is provided with a washbasin 50, which will be described later.

[0035] The first lining 21 is installed with a gap S1 between it and the floor surface F. That is, the first portion 22 and the second portion 23 are installed on the wall surface W of the toilet room TR. As shown in FIG. 2, the height dimension H1 from the floor surface F to the bottom surface 22a of the first portion 22 is the same as the height dimension H1 from the floor surface F to the bottom surface 23a of the second portion 23. That is, in the first lining 21, the bottom surface 22a of the first portion 22 and the bottom surface 23a of the second portion 23 extend in a straight line.

[0036] The height dimension H1 of the first lining 21 is, for example, 300 mm or more (preferably 400 mm or more). As a result, the interval S1 allows, for example, a wheelchair user to insert their feet when using a washbasin 50, which will be described later. In addition, the interval S1 makes it easy to turn the wheelchair around when moving, for example. This makes the toilet room TR easy to use for wheelchair users, for example. Also, as shown in FIG. 2, the height dimension H1 from the floor surface F to the bottom surfaces 22a, 23a of the first lining 21 is equal to or greater than the height dimension H2 from the floor surface F to the toilet bowl 12.

[0037] As shown by the two-dot chain line in Fig. 2, an accessory member 200 such as a dust box for collecting garbage may be attached to the bottom surface 22a of the first portion 22. Also, as shown in Fig. 3, an auxiliary stand 210 extending to the toilet bowl 12 may be attached to the bottom surface 22a of the first portion 22. The auxiliary stand 210 is an auxiliary member on which a wheelchair user can sit or rest their hands when moving between the toilet bowl 12 and the wheelchair. The accessory member 200 and the auxiliary stand 210 are adapted to be selectively attached to the first portion 22.

[0038] In the first section 22, operation parts such as a call button 32, an operation remote control 34, and a toilet flush button 36, as well as a paper roll holder 38 and a handrail 40 are provided facing the toilet bowl 12. The call button 32 is an operation part for notifying the outside of the occurrence of an abnormality such as an emergency, and is provided in multiple places in the toilet room TR, for example. In addition, a hand washing basin 16 is installed on the upper surface of the first section 22.

[0039] The operation remote control 34 is an operation unit for instructing the toilet seat device 14 to operate the body cleansing function unit, etc. The operation remote control 34 is disposed below the hand washing basin 16. The operation remote control 34 has a plurality of operation buttons, such as a stop button, a rear cleansing button, and a bidet cleansing button.

[0040] The toilet flush button 36 is an operating part for flushing the toilet 12. By operating the toilet flush button 36, flush water is supplied to the bowl portion of the toilet 12, flushing the bowl portion of the toilet 12. The operation remote control 34 and the toilet flush button 36 may be integrated together.

[0041] The paper roll holder 38 is disposed within reach of a user seated on the toilet seat 14a. The paper roll holder 38 is disposed, for example, below the operation remote control 34 and the toilet flush button 36.

[0042] The second section 23 is formed in a box shape by a front panel 23b extending upward from the bottom surface portion 23a and a side panel 23c covering the side of the second section 23 between the front panel 23b and the wall surface W. A faucet unit 60 and a drain trap, which will be described later, are housed inside the second section 23. The second section 23 also has an opening 23d for performing maintenance on the electric water heater 64 housed inside the second section 23. In this example, the opening 23d is provided in the bottom surface portion 23a. The opening 23d is covered by an openable and closable lid portion 24. The opening 23d may be provided in the front panel 23b or the side panel 23c of the second section 23. The opening 23d may be used for maintenance of other devices, not limited to the electric water heater 64.

[0043] Next, the washbasin 50, the faucet unit 60, and the liquid soap unit 80 will be described. FIG. 4 is a block diagram showing a control system for the faucet unit and the liquid soap unit. FIG. 5 is an enlarged front view of the second portion in FIG. 2 with the front panel removed. FIG. 6 is a plan view of the second portion seen from above.

[0044] The washbasin 50 is installed on the upper surface of the second portion 23 of the first lining 21. The washbasin 50 may be attached to the wall surface of the toilet room TR. The washbasin 50 is installed at a height that allows a user in a wheelchair to use it, for example. As shown in FIG. 2, the washbasin 50 is provided at a position farther away from the toilet bowl 12 than the hand wash basin 16. The washbasin 50 is located to the left and front as viewed from a user seated on the toilet seat 14a. The washbasin 50 has a bowl portion 52 recessed downward, and a first counter 54 and a second counter 55 located on the sides (both sides in the width direction) of the bowl portion 52.

[0045] 6, bowl portion 52 has receiving portion 52a that receives hot and cold water discharged from faucet device 66, first mounting portion 52b located above receiving portion 52a and to which faucet device 66 is attached, and second mounting portion 52c located above receiving portion 52a and to which liquid soap device 86 is attached. In other words, bowl portion 52 is formed in a stepped shape in the vertical direction by receiving portion 52a, first mounting portion 52b, and second mounting portion 52c.

[0046] The receiving portion 52a has a bottom portion 52a1, a first wall portion 52a2 rising from the bottom portion 52a1 toward the first mounting portion 52b, a second wall portion 52a3 rising from the bottom portion 52a1 toward the second mounting portion 52c, and an inclined portion 52a4 located forward of the first wall portion 52a2 and the second wall portion 52a3 and extending diagonally upward from the bottom portion 52a1.

[0047] The bottom portion 52a1 has a drain outlet 52a5. The drain outlet 52a5 is formed, for example, in the center of the width L1 of the bowl portion 52. Hot and cold water discharged from the water faucet device 66 flows from the drain outlet 52a5 into the sewer system.

[0048] As shown in Figs. 5 to 7, the first mounting portion 52b and the second mounting portion 52c are provided within the width L1 of the bowl portion 52. The first mounting portion 52b is located between the bottom portion 52a1 and the first counter 54 in the vertical direction. The second mounting portion 52c is located between the bottom portion 52a1 and the second counter 55 in the vertical direction. The first mounting portion 52b and the second mounting portion 52c are provided separated from each other in the left-right direction with the bottom portion 52a1 in between.

[0049] 5 and 6, the first and second counters 54, 55 extend horizontally from the upper end of the bowl portion 52. The first and second counters 54, 55 are located higher than the first mounting portion 52b and the second mounting portion 52c. The first and second counters 54, 55 are, for example, horizontal surfaces on which luggage and the like can be placed.

[0050] The washbasin 50 has a front portion 50a extending downward from the front end of the inclined portion 52a4 of the bowl portion 52 and the front ends of the first and second counters 54, 55, a first side portion 50b extending downward from the end of the first counter 54, and a second side portion 50c extending downward from the end of the second counter 55.

[0051] The front surface portion 50a is formed in a concave shape when viewed from the front. The front surface portion 50a protrudes forward beyond the front plate 23b of the second portion 23 of the first lining 21. The first side surface portion 50b is continuous with the side plate 23c of the second portion 23 in the up-down direction. The second side surface portion 50c extends from the front surface portion 50a toward the first portion 22 of the first lining 21.

[0052] 8, the washbasin 50 has a first space S2 between the bowl portion 52 and the first counter 54. Specifically, the first space S2 is a portion surrounded by the bowl portion 52, the first counter 54, the front portion 50a, and the first side portion 50b.

[0053] 7 and 8, the washbasin 50 has a second space S3 between the front surface 50a and the bowl portion 52. Specifically, the second space S3 is formed between the front surface 50a and the inclined portion 52a4 of the bowl portion 52.

[0054] The washbasin 50 also has a third space S4 between the bowl portion 52 and the second counter 55. Specifically, the third space S4 is a portion surrounded by the bowl portion 52, the second counter 54, the front portion 50a, and the second side portion 50c.

[0055] The second space S3 communicates with the first space S2 at its right end and with the third space S4 at its left end. The first space S2, the second space S3, and the third space S4 communicate with the internal space of the second section 23 in the vertical direction. A part of an electric water heater 64 (described later) is disposed in the first space S2. Meanwhile, a part of a supply pipe 71 (described later) is disposed in the second space S3 and the third space S4.

[0056] The faucet unit 60 discharges hot and cold water toward the bowl portion 52 of the washbasin 50. The faucet unit 60 has an automatic faucet function portion 62, an electric water heater 64, and a faucet device 66.

[0057] As shown in Fig. 5, the automatic water faucet function unit 62 is provided in the second portion 23 of the first lining 21. As shown in Fig. 4, the automatic water faucet function unit 62 has an on-off valve 62a and a control unit 62b. The on-off valve 62a is provided in a pipe 70 that guides water supplied from a water supply source 100 to an electric water heater 64. The water supply source 100 is, for example, a water supply system. The on-off valve 62a is, for example, a solenoid valve, and its open / closed state is controlled by the control unit 62b.

[0058] The control unit 62b is connected to a power source (not shown). The control unit 62b is electrically connected to the on-off valve 62a and controls the operation of the on-off valve 62a. The control unit 62b is also electrically connected to a faucet sensor 66c of the faucet device 66. The control unit 62b switches the open / close state of the on-off valve 62a according to a command signal transmitted from the faucet sensor 66c.

[0059] The electric water heater 64 is located downstream of the on-off valve 62a and connected to the pipe 70. The electric water heater 64 has a tank, a heater provided in the tank, and a control unit that controls the heater (none of which are shown). The electric water heater 64 has, for example, a rectangular parallelepiped shape that is long in the vertical direction, and is a storage-type electric water heater that can boil and store hot water in a 1-liter tank. An inlet portion 64a to which the pipe 70 is connected and an outlet portion 64b to which the supply pipe 71 is connected are provided on the upper surface of the electric water heater 64. As shown in FIG. 5, the electric water heater 64 is disposed in the first portion 23 of the first lining 21. The positional relationship of the electric water heater 64 will be described in detail later.

[0060] The faucet device 66 is attached to the first attachment portion 52b of the bowl portion 52. The faucet device 66 discharges hot and cold water toward the receiving portion 52a. In other words, the faucet device 66 is a faucet spout having an outlet for discharging hot and cold water. The outlet of the faucet device 66 is located, for example, above the receiving portion 52a. The electric water heater 64 and the faucet device 66 are connected by a supply pipe 71. The hot and cold water discharged from the electric water heater 64 is supplied to the faucet device 66 via the supply pipe 71.

[0061] The faucet device 66 has a faucet sensor 66c. The faucet sensor 66c is, for example, an infrared emitting / receiving sensor, and detects a hand held out toward the bowl portion 52. The faucet sensor 66c is not limited to an infrared emitting / receiving sensor, and may be, for example, a pyroelectric sensor or a microwave sensor. The faucet sensor 66c may be any sensor that can detect a hand held out toward the bowl portion 52.

[0062] When the faucet sensor 66c detects a hand, it transmits a command signal indicating that a hand has been detected to the control unit 62b of the automatic faucet function unit 62. When the control unit 62b receives this command signal, it switches the on-off valve 62a from a closed state to an open state. This causes hot and cold water to be automatically dispensed from the faucet device 66.

[0063] Then, when the control unit 62b receives a notification that the faucet sensor 66c has not detected a hand, it switches the on-off valve 62a from an open state to a closed state, causing the hot and cold water discharged from the faucet device 66 to automatically stop.

[0064] As shown in Fig. 6, the faucet device 66 extends diagonally forward. As a result, the landing position X of the hot and cold water discharged from the faucet device 66 is closer to the front portion 50a of the washbasin 50. The landing position X of the hot and cold water is located, for example, forward of the center of the depth length L2 of the bowl portion 52. In this example, the landing position X is the inclined portion 52a4 of the bowl portion 52. The hot and cold water that lands on the inclined portion 52a4 flows down the inclined portion 52a4 and is drained from the drain outlet 52a5 of the bottom portion 52a1. By moving the landing position X closer to the front side of the bowl portion 52, the faucet device 66 makes it easier for the user to wash their hands.

[0065] The faucet device 66 is attached to the first attachment portion 52b, which is located below the first counter 54 and the second counter 55. This causes the user to hold out their hands below the first and second counters 54, 55 when washing their hands. This prevents the first counter 54 and the second counter 55 from getting wet due to hot or cold water splashing from the bowl portion 52 or the hands.

[0066] The liquid soap unit 80 discharges liquid soap toward the bowl portion 52 of the washbasin 50. The liquid soap unit 80 has a liquid soap tank 82, a liquid soap function portion 84, and a liquid soap device 86.

[0067] The liquid soap tank 82 stores liquid soap. The liquid soap tank 82 is installed, for example, in the first portion 22 of the first lining 21. A pipe 90 that supplies liquid soap to the liquid soap device 86 is connected to the liquid soap tank 82.

[0068] The liquid soap function unit 84 is provided, for example, in the first portion 22 of the first lining 21. The liquid soap function unit 84 has a pump 84a and a control unit 84b. The pump 84a is located between the liquid soap tank 82 and the liquid soap device 86 and is provided in the pipeline 90. The operation of the pump 84a is controlled by the control unit 84b. The pump 84a sucks up the liquid soap stored in the liquid soap tank 82 and supplies it to the liquid soap device 86.

[0069] The liquid soap device 86 is attached to the second attachment portion 52c of the bowl portion 52. The liquid soap device 86 discharges liquid soap toward the receiving portion 52a. In other words, the liquid soap device 86 is a liquid soap spout having a discharge port that discharges liquid soap. The discharge port of the liquid soap device 86 is located, for example, above the receiving portion 52a. The liquid soap device 86 is disposed on the opposite side of the receiving portion 52a to the faucet device 66.

[0070] The liquid soap device 86 has a liquid soap sensor 86c. The liquid soap sensor 86c is, for example, an infrared light emitting / receiving sensor, and detects a hand held out toward the bowl portion 52. The liquid soap sensor 86c is not limited to an infrared light emitting / receiving sensor, and may be, for example, a pyroelectric sensor or a microwave sensor. The liquid soap sensor 86c may be any sensor capable of detecting a hand held out toward the bowl portion 52. The liquid soap sensor 86c and the faucet sensor 66c are, for example, the same sensor.

[0071] When the liquid soap sensor 86c detects a hand, it transmits a command signal indicating that a hand has been detected to the control unit 84b of the liquid soap function unit 84. When the control unit 84b receives this command signal, it operates the pump 84a. As a result, the liquid soap in the liquid soap tank 82 is sucked up by the pump 84a, and the liquid soap is automatically discharged from the liquid soap device 86.

[0072] Then, the control unit 84b stops the operation of the pump 84a when it receives a notification that the liquid soap sensor 86c has not detected the hands. As a result, the liquid soap being discharged from the liquid soap device 86 automatically stops.

[0073] As shown in Fig. 6, the liquid soap device 86 also extends diagonally forward, similar to the faucet device 66. As a result, the landing position Y of the liquid soap dispensed from the liquid soap device 86 is closer to the front portion 50a of the washbasin 50. The landing position Y of the liquid soap is located, for example, forward of the center of the depth length L2 of the bowl portion 52. In this example, the landing position Y is the inclined portion 52a4 of the bowl portion 52. By moving the landing position Y closer to the front side of the bowl portion 52, the liquid soap device 86 makes it easier for the user to wash their hands.

[0074] The liquid soap device 86 is attached to the second attachment portion 52c, which is located lower than the first counter 54 and the second counter 55. This causes the user to hold out their hands below the first and second counters 54, 55 when washing their hands. This prevents the first counter 54 and the second counter 55 from getting wet with liquid soap splashed from the bowl portion 52 or the hands. The water faucet device 66 may be attached to the second attachment portion 52c, and the liquid soap device 86 may be attached to the first attachment portion 52b.

[0075] The mirror 95 is located above the washbasin 50 and is provided on the wall W of the toilet room TR. The faucet device 66 and the liquid soap device 86 are attached to the first and second mounting parts 52b, 52c located below the first and second counters 54, 55. This prevents the faucet device 66 and the liquid soap device 86 from being reflected in the mirror 95 even if the position of the mirror 95 is lowered. This makes it possible to improve the usability of the mirror 95.

[0076] Next, the relative positions of the electric water heater 64 and the supply pipe 71 disposed within the first lining 21 will be described.

[0077] In order to improve usability for wheelchair users and the like, the toilet unit 10 has a space S1 between the first lining 21 and the floor surface F. If the height dimension H1 between the first lining 21 and the floor surface F is increased and the height of the washbasin 50 is also increased, the washbasin 50 may become less convenient for wheelchair users and the like to use.

[0078] Therefore, the height dimension H1 of the first lining 21 must be increased without changing the height of the washbasin 50. If this is done, the internal space of the first lining 21 will become narrower, and it may become impossible to mount various devices inside the first lining 21. In particular, since the electric water heater 64 is a large device that is vertically long, it may become difficult to store it inside the first lining 21.

[0079] Therefore, at least a part of the electric water heater 64 is disposed in the first space S2 between the bowl section 52 and the first counter 54. As shown in Figs. 5 to 8, the electric water heater 64 is disposed so that an upper part including the inlet section 64a and the outlet section 64b is located in the first space S2, and the other lower part is located inside the second section 23. That is, as shown in Fig. 7, in a side view of the washbasin 50 and the electric water heater 64, at least a part of the washbasin 50 and the electric water heater 64 overlap in the front-rear direction. In this way, the toilet unit 10 defines the dead space located below the first counter 54 of the washbasin 50 as the first space S2 into which the electric water heater 64 can be inserted.

[0080] As a result, even if, for example, the height dimension of the electric water heater 64 is greater than the height dimension of the second section 23, the electric water heater 64 can be stored by utilizing the first space below the first counter 54 of the washbasin 50.

[0081] Here, for example, if the water faucet device 66 is provided on the first counter 54, the supply pipe 71 connected to the water faucet device 66 will enter the first space S2. This may result in interference between the electric water heater 64 and the supply pipe 71, making it difficult to install the electric water heater 64 in the first space S2.

[0082] 6, the first mounting portion 52b to which the faucet device 66 or the liquid soap device 86 is attached is provided within the width L1 of the bowl portion 52. As a result, the supply pipe 71 disposed below the faucet device 66 does not enter the first space S2, making it possible to make full use of the first space S2 and to place the electric water heater 64 in the first space S2.

[0083] The supply pipe 71 is arranged in the second space S3. The second space S3 is a narrow space between the front part 50a of the washbasin 50 and the inclined part 52a4 of the bowl part 52. By using such a second space S3, the degree of freedom in arranging other devices arranged in the second part 23 can be improved.

[0084] As shown in Fig. 9, the electric water heater 64 is detachable through an opening 23d provided in the bottom surface 23a of the second section 23. Maintenance of the electric water heater 64 can be performed through the opening 23d. The bottom surface 23a is provided with a lid 24 that can open and close the opening 23d. The lid 24 is slidable in the left-right direction on the bottom surface 23a.

[0085] When storing the electric water heater 64 in the second section 23, the front panel 23b of the second section 23 is removed and the lid section 24 is moved to the left to open the opening 23d. Then, a pipe 70 is connected to the automatic faucet function section 62 and the inlet section 64a of the electric water heater 64, and a supply pipe 71 is connected to the outlet section 64b of the electric water heater 64 and the faucet device 66.

[0086] In this state, the electric water heater 64 is inserted into the second section 23 from the opening 23d, while the supply pipe 71 is disposed in the second space S3. Then, the lid section 24 is moved rightward to place the electric water heater 64 on the lid section 24. As a result, the electric water heater 64 is disposed so that its upper portion is located in the first space S2, and the remaining lower portion is located inside the second section 23. Finally, the front panel 23b is attached to the second section 23, and the installation work of the electric water heater 64 is completed.

[0087] On the other hand, when removing the electric water heater 64 from the second section 23, the front panel 23b is removed from the second section 23. Next, while holding the electric water heater 64, the cover part 24 is moved to the left. Then, the electric water heater 64 is moved downward from the opening 23d, whereby the electric water heater 64 can be removed from the second section 23.

[0088] Here, for example, if the length of the supply pipe 71 is short, the distance that the electric water heater 64 can be moved when attaching or detaching the electric water heater 64 becomes short, which may reduce the workability of the attachment and detachment work. In this example, the supply pipe 71 extends from the second space S3 through the third space S4 to the water faucet device 66. Therefore, since the supply pipe 71 has a sufficient length, the workability of the work when attaching or detaching the electric water heater 64 in the second section 23 can be improved.

[0089] The height dimension H1 of the second portion 23 of the first lining 21 is equal to or greater than the height dimension H2 of the toilet bowl 12. Furthermore, in the first lining 21, the height dimension H1 from the floor surface F of the bottom surface portion 22a of the first portion 22 and the bottom surface portion 23a of the second portion 23 are the same. This allows, for example, a wheelchair user to insert their feet below the first portion 22 and the second portion 23. Therefore, the toilet unit 10 allows the wheelchair to turn and move stably.

[0090] In the above embodiment, an example has been described in which a portion of the electric water heater 64 is disposed in the first space S2 located below the first counter 54. However, the present invention is not limited to this, and for example, a portion of the electric water heater 64 may be disposed in the third space S4 below the second counter 55. In this case, the space below the second counter 55 becomes the first space, and the space below the first counter 54 becomes the third space.

[0091] In the above embodiment, the water faucet unit 60 has been described as a main stop type having an on-off valve 62a upstream of the electric water heater 64. However, the present invention is not limited to this, and may be a first stop type having an on-off valve downstream of the electric water heater 64, for example.
