Description

[Technical Field]

[0001] The disclosed embodiments relate to a toilet bowl system. [Background technology]

[0002] Various toilet apparatuses equipped with wall-hung flush toilets have been proposed in the past (see, for example, Patent Document 1). In such toilet apparatuses, a water supply path including a water storage tank and water supply pipe is provided behind the wall to which the toilet body is attached. In other words, the water supply path is concealed behind the wall, and flush water is supplied to the toilet body from the concealed water supply path. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2013 / 037488 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the prior art did not address the replacement (remodeling) of toilet equipment. Specifically, the location where the existing water supply line emerges from the wall varies depending on the type of toilet equipment, or in other words, the manufacturer of the toilet equipment. Therefore, for example, when connecting the exit point of the existing water supply line to the water supply inlet of a new toilet equipment via a connecting member, it is necessary to prepare a connecting member corresponding to each of the multiple water supply line exit points, which increases the number of parts required for replacement.

[0005] Furthermore, in a newly installed toilet system, for example, if the water storage tank is installed on the toilet body, the existing water storage tank behind the wall becomes unnecessary, but a water supply pipe for the new toilet system is required. Therefore, when replacing the toilet system, it is possible to destroy the wall, remove the existing water supply route including the water storage tank behind the wall, and install a new water supply pipe for the new toilet system, but this increases the labor required for the replacement work. As such, the prior art left room for improvement in terms of making it easier to replace toilet systems regardless of the type of existing toilet system.

[0006] An object of one aspect of the embodiment is to provide a toilet apparatus that can be easily replaced regardless of the type of existing toilet apparatus. [Means for solving the problem]

[0007] A toilet device according to one aspect of the embodiment comprises a toilet body having a bowl portion for receiving waste, a water supply portion provided in the toilet body and including a water storage tank for storing flushing water to be supplied to the bowl portion, and a water supply pipe having an upstream end connected to an existing stop valve located on the back side of the wall portion to which the toilet body is attached, passing through an existing water supply path located on the back side of the wall portion, and having a downstream end connected to the water supply portion.

[0008] In this way, the toilet apparatus includes a water supply pipe whose upstream end is connected to the existing stop valve, runs through the existing water supply line, and whose downstream end is connected to the water supply unit. This allows the existing stop valve to be easily connected to the water supply unit for the new toilet apparatus, regardless of the location of the existing water supply line. Furthermore, because the water supply pipe runs through the existing water supply line located behind the wall, the existing water supply line can function as a sheath for the water supply pipe. Therefore, when replacing the toilet apparatus, there is no need to destroy the wall to remove the water supply line or install new water supply piping for the new toilet apparatus, and the toilet apparatus can be easily replaced. In this way, this embodiment allows the toilet apparatus to be easily replaced regardless of the type of existing toilet apparatus.

[0009] The water supply pipe is arranged from a central region including the center of the toilet body in the left-right direction toward the inside of the toilet body.

[0010] As a result, the water supply pipe is arranged inside the toilet body from a specified position (central area) in the toilet body, regardless of the extraction position of the existing water supply path, making it easy to connect the water supply pipe to the water supply section of the toilet body.

[0011] The toilet also includes a sanitary washing device that is installed on the toilet body and discharges washing water to wash the user's private parts, and the water supply pipe supplies water to the water storage tank and the sanitary washing device.

[0012] In this way, even when a toilet apparatus is equipped with a sanitary washing device, water is supplied to the sanitary washing device from the water supply pipe. Therefore, in this embodiment, an existing toilet apparatus can be easily replaced with a toilet apparatus equipped with a sanitary washing device.

[0013] In addition, the water supply section is provided in the toilet body and includes a toilet side water supply pipe whose upstream end is connected to the water supply pipe and whose downstream end is connected to the water storage tank, and the toilet side water supply pipe branches and is connected to the sanitary washing device.

[0014] In this way, the toilet-side water supply pipe of the water supply section located downstream of the water supply pipe is branched into a flow path for the water storage tank and a flow path for the sanitary flushing device, so it is possible to use a single water supply pipe that is common (shared) for both the water storage tank and the sanitary flushing device. This makes it easy to replace the toilet device when, for example, replacing the toilet device by simply passing the water supply pipe through the existing water supply path.

[0015] The water supply system also includes a packing that can be attached to the existing water supply path, thereby preventing water leakage from the existing water supply path.

[0016] The packing is attached to the downstream opening of the existing water supply path. In this way, since the packing is attached to the downstream opening of the existing water supply path, which is prone to water leakage, it is possible to effectively suppress water leakage from the downstream opening. [Effects of the Invention]

[0017] According to one aspect of the embodiment, a toilet apparatus can be easily replaced regardless of the type of existing toilet apparatus. [Brief explanation of the drawings]

[0018] [Figure 1] FIG. 1 is a perspective view of a toilet apparatus according to an embodiment. [Figure 2] FIG. 2 is a front view of the toilet apparatus according to the embodiment. [Figure 3] FIG. 3 is a side cross-sectional view of the toilet apparatus according to the embodiment. [Figure 4] FIG. 4 is an enlarged perspective view of the vicinity of the packing. DETAILED DESCRIPTION OF THE INVENTION

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the toilet device disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described below.

[0020] A toilet apparatus T according to an embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a perspective view of the toilet apparatus T according to an embodiment. Fig. 2 is a front view of the toilet apparatus T according to an embodiment. Figs. 1 and 2, as well as Fig. 3 and subsequent figures described below, are all schematic diagrams.

[0021] 1 and other figures illustrate a three-dimensional Cartesian coordinate system in which mutually orthogonal X-, Y-, and Z-axis directions are defined, with the positive Z-axis direction being the vertically upward direction. In the following description, the positive X-axis direction may be referred to as "left," the negative X-axis direction as "right," the positive Y-axis direction as "forward," and the negative Y-axis direction as "rearward." Therefore, in the following description, the X-axis direction may be referred to as the left-right direction, the Y-axis direction as the front-to-back direction, and the Z-axis direction as the up-down direction (vertical direction).

[0022] As shown in FIGS. 1 and 2, a toilet apparatus T according to an embodiment comprises a tank frame apparatus 1, a flush toilet 2, and a sanitary washing device 3 (shown only in FIG. 1).

[0023] The toilet apparatus T shown in Figure 1 etc. represents a toilet apparatus after replacement (remodeling). Here, the tank frame apparatus 1 is what was included in the toilet apparatus before replacement, in other words, what was already installed. The flush toilet 2 and sanitary washing apparatus 3 are new installations that were made as a result of the replacement.

[0024] The tank frame device 1 is disposed in the back-wall space of the toilet room. The back-wall space is the space located on the opposite side of the toilet room wall W from the interior of the toilet room in which the flush toilet 2 is disposed. The back-wall space is concealed by the wall W.

[0025] The tank frame device 1 includes a frame 11, a water supply path 12, and a drain pipe 13. The frame 11, the water supply path 12, and the drain pipe 13 are arranged in a space behind a wall.

[0026] The frame 11 is erected in the back-of-wall space and supports the water supply path 12 and the drain pipe 13. Specifically, the frame 11 includes a plurality of (two in this case) support columns 11a extending vertically upward from the floor surface of the back-of-wall space, and a plurality of (three in this case) beams 11b-11d extending parallel to the floor surface of the back-of-wall space and connecting the support columns 11a to each other. Note that the number of support columns 11a and beams 11b-11d included in the frame 11 is not limited to the above example.

[0027] Beam 11b is provided on the upper section of frame 11. Beam 11c is provided on the middle section of frame 11, and beam 11d is provided on the lower section of frame 11. The rear end of the flush toilet 2 is fixed to beam 11c via wall W. Specifically, multiple mounting holes 14 are formed in beam 11c, and rod-shaped support members (not shown) are inserted through the mounting holes 14. The support members protrude into the interior of the toilet room via wall W. Meanwhile, insertion holes are formed in the rear end of the flush toilet 2 at positions that correspond to the mounting holes 14 in beam 11c. By inserting the support members through these insertion holes, the flush toilet 2 is supported by the frame 11 and attached to wall W.

[0028] The water supply path 12 is the path that supplied flush water to the previous flush toilet in the previous toilet device. The water supply path 12 comprises a water storage tank 12a and a water supply pipe 12b. Because the water storage tank 12a and the water supply pipe 12b are already installed, hereinafter the water storage tank 12a will be referred to as the "existing tank 12a" and the water supply pipe 12b as the "existing water supply pipe 12b." Because the existing tank 12a and the existing water supply pipe 12b are concealed by the wall W, they can also be referred to as "concealed tanks" and "concealed water supply pipes."

[0029] The existing tank 12a stored flush water in the toilet system before replacement. The existing water supply pipe 12b connected the existing tank 12a to the flush toilet before replacement in the toilet system before replacement, and supplied the flush water stored in the existing tank 12a to the flush toilet.

[0030] An existing stop valve 15 is provided inside the existing tank 12a. Therefore, like the existing tank 12a, the existing stop valve 15 is also arranged (concealed) on the back side of the wall W. The stop valve 15 is connected to a water supply source A (see FIG. 3) such as a water line. Note that, although an example in which the existing stop valve 15 is provided inside the existing tank 12a has been shown here, the present invention is not limited to this and the existing stop valve 15 may be provided outside the existing tank 12a.

[0031] In the replaced toilet apparatus T, a water storage tank 41 (see Figure 3) is provided on the toilet body side, so flush water is not stored in the existing tank 12a. In this way, because flush water is not stored in the existing tank 12a, the water supply equipment such as a float valve that was provided in the existing tank 12a (more precisely, the water supply equipment downstream of the stop valve 15) is removed during replacement. In other words, in the existing tank 12a, the existing stop valve 15 is left in place, but the water supply equipment downstream of the stop valve 15 is removed.

[0032] An inspection opening 12a1 is formed on the side of the existing tank 12a. The opening 12a1 is covered by a lid 12a2. A wall-side opening Wa is formed in the wall W at a position corresponding to the opening 12a1 of the existing tank 12a. The wall-side opening Wa is covered by a wall-side lid Wb. Therefore, by removing the wall-side lid Wb and the lid 12a2, the replacement worker can access the inside of the existing tank 12a (e.g., the stop valve 15) through the wall-side opening Wa of the wall W and the opening 12a1 of the existing tank 12a.

[0033] The existing water supply pipe 12b has an extending portion 12b1 and a bent portion 12b2. The upstream end 12b3 of extending portion 12b1 is connected to the lower end 12a3 of the existing tank 12a, and is configured to extend downward from lower end 12a3. Bent portion 12b2 is connected to extending portion 12b1, and is configured to bend horizontally from bent portion 12b2 toward the flush toilet 2. Bent portion 12b2 is inserted through insertion hole 16 of beam portion 11b, and the downstream end 12b4 of bent portion 12b2 is exposed toward the flush toilet 2. In other words, the downstream end 12b4 of the existing water supply pipe 12b is exposed toward the flush toilet 2.

[0034] In the replaced toilet apparatus T, flush water is not stored in the existing tank 12a, and therefore flush water does not flow through the existing water supply pipe 12b itself. However, in the replaced toilet apparatus T, the water supply pipe 70 is configured to pass through the inside of the existing water supply path 12, which includes the existing tank 12a and the existing water supply pipe 12b, but this will be described later.

[0035] The drain pipe 13 is a tubular member. The drain pipe 13 is a drainage flow path that extends vertically upward from the floor surface of the space behind the wall and opens horizontally towards the flush toilet 2. The drain trap section 24 of the flush toilet 2 (see Figure 3), which will be described later, is connected to the drain pipe 13, and drains flush water from the flush toilet 2.

[0036] Next, the flush toilet 2 and sanitary washing device 3 will be explained with reference to Figure 3. Figure 3 is a side cross-sectional view of a toilet device T according to an embodiment.

[0037] As shown in Figure 3, the flush toilet 2 comprises a toilet body 20 and a water supply section 30. The flush toilet 2 is a so-called wall-hung flush toilet, in which the toilet body 20 is fixed to a wall surface WS of a wall section W of the toilet room.

[0038] The toilet body 20 is made of ceramic. However, the toilet body 20 is not limited to being made of ceramic, and may be made of resin, or a combination of ceramic and resin. The toilet body 20 comprises a bowl portion 21, a rim portion 22, a spout 23, and a drain trap portion 24.

[0039] Bowl portion 21 is formed in a concave shape. Bowl portion 21 has bowl surface 21a that receives waste. Rim portion 22 is provided above bowl portion 21. Rim portion 22 is provided on the upper edge of bowl surface 21a. Water outlet 23 is formed inside bowl portion 21 and discharges flush water from tank portion 40 onto bowl surface 21a inside bowl portion 21.

[0040] Drain trap portion 24 forms part of a drain flow path that discharges waste inside the bowl portion. One end of drain trap portion 24 is connected to the lower part of bowl portion 21, and the other end is connected to drain pipe 13. One end of drain trap portion 24 is inlet portion 24a of drain trap portion 24, which also serves as the inlet portion of the drain flow path.

[0041] Specifically, drain trap section 24 includes, from the upstream side to the downstream side, a curved pipe line 24b and a descending pipe line 24c. An upstream inlet section (inlet section 24a of drain trap section 24) of curved pipe line 24b is connected to the lower part of bowl section 21. Then, a drain flow path is formed that extends from inlet section 24a to a rearward and downward lowest end section 24d, and then rises to a rearward and upward peak section 24e.

[0042] The descending pipe 24c forms a drainage flow path that descends rearward and downward from the top 24e of the curved pipe 24b and then connects to the drain socket 26. A water seal (water seal surface WL) is formed in the area of ​​the curved pipe 24b upstream (forward) of the top 24e. The drain pipe 13 is directed toward the toilet body 20 (forward), and the inlet located at the upstream end of the drain pipe 13 is connected to the outlet 24f at the downstream end of the drain trap 24 via the drain socket 26.

[0043] The water supply section 30 comprises a toilet side water supply pipe 31, a stop valve 32, a valve unit 33, and a tank section 40. The toilet side water supply pipe 31, stop valve 32, valve unit 33, and tank section 40 are provided in the toilet body 20. The stop valve 32 is provided at the upstream end of the toilet side water supply pipe 31. The toilet side water supply pipe 31 is connected to a water supply pipe 70 via the stop valve 32, which will be described later.

[0044] The toilet-side water supply pipe 31 branches into a first water supply pipe 31a and a second water supply pipe 31b at a branch point P between the stop valve 32 and the valve unit 33. The first water supply pipe 31a is a pipe that supplies flush water to the water storage tank 41 (described below) of the flush toilet 2, and the second water supply pipe 31b is a pipe that supplies flush water to the sanitary washing device 3. In this way, the toilet-side water supply pipe 31 branches and is connected to the sanitary washing device 3.

[0045] The valve unit 33 is provided on the first water supply pipe 31a. The valve unit 33 is driven in response to a control signal output from a toilet control device (not shown), and opens and closes the first water supply pipe 31a. For example, the valve unit 33 is equipped with a solenoid valve that opens and closes in response to the control signal, and can switch between supplying and stopping flush water to be supplied to the flush toilet 2's water tank 41 (described below).

[0046] A water supply nozzle 34 is provided at the downstream end of the toilet side water supply pipe 31 (more precisely, the first water supply pipe 31a). The water supply nozzle 34 is connected to the water storage tank 41 of the tank section 40, and supplies flush water from the valve unit 33 to the water storage tank 41. In this way, the water storage tank 41 is connected to the downstream end of the toilet side water supply pipe 31 (more precisely, the first water supply pipe 31a).

[0047] The tank section 40 comprises a water storage tank 41, a connecting section 42, and a pressure pump 43. The water storage tank 41 is connected to the water supply nozzle 34 of the toilet side water supply pipe 31 via the connecting section 42. The water storage tank 41 stores flush water supplied from the water supply nozzle 34 of the toilet side water supply pipe 31. In other words, the water storage tank 41 stores flush water to be supplied to the bowl section 21. The water storage tank 41 is incorporated into the lower part of the toilet body 20. In this way, in the replaced toilet apparatus T, the water storage tank 41 is provided in the toilet body 20. The position at which the water storage tank 41 is provided in the toilet body 20 can be set as desired.

[0048] The pressure pump 43 pressurizes flush water from the water storage tank 41 and supplies it to the bowl section 21 of the toilet body 20. The pressure pump 43 is built into the toilet body 20. When the pressure pump 43 is activated, the flush water stored in the water storage tank 41 is pressurized and flows through the connecting pipe 50 and supplied to the toilet body 20, and further flows through a water conduit (not shown) provided in the toilet body 20 and is supplied from the discharge port 23 to the bowl section 21 (more precisely, the bowl surface 21a).

[0049] An overflow pipe 44 is connected to the connecting part 42. The overflow pipe 44 discharges flush water into the bowl part 21 of the toilet body 20 when the flush water supplied to the water storage tank 41 exceeds a specified water level.

[0050] The sanitary washing device 3 is a device that cleanses the private parts of the user by discharging washing water. The sanitary washing device 3 is installed on the toilet body 20, more specifically, on the top surface of the toilet body 20 (see Figure 1).

[0051] The sanitary washing device 3 includes a sanitary washing water supply section 60. The sanitary washing water supply section 60 includes a sanitary washing water supply pipe 61, a valve unit 62, a hot water storage tank 63, a switching valve 64, and a nozzle 65. Note that the sanitary washing water supply section 60 may be configured to include other components such as a vacuum breaker in addition to the valve unit 62, etc.

[0052] The upstream end of the sanitary washing water supply pipe 61 is connected to the second water supply pipe 31b branched off from the toilet-side water supply pipe 31. Note that, although an example has been shown in which the sanitary washing water supply pipe 61 and the second water supply pipe 31b are connected separately, this is not limiting, and the sanitary washing water supply pipe 61 and the second water supply pipe 31b may be integrated.

[0053] The sanitary washing water supply pipe 61 is provided with, from upstream to downstream, a valve unit 62, a hot water storage tank 63, a switching valve 64, and a nozzle 65. The valve unit 62 is driven in response to a control signal output from a control device (not shown) of the sanitary washing device 3, and opens and closes the sanitary washing water supply pipe 61. For example, the valve unit 62 includes a solenoid valve that opens and closes in response to the above-mentioned control signal, and can switch between supplying and stopping the washing water supplied to the nozzle 65.

[0054] The hot water storage tank 63 stores the flush water to be supplied to the nozzle 65. The hot water storage tank 63 is provided with a heater (not shown), and the stored flush water is heated by the heater. The switching valve 64 is driven in response to a control signal output from a control device (not shown) of the sanitary washing device 3, and switches the outflow destination of the flush water flowing through the sanitary washing water supply pipe 61. Specifically, the switching valve 64 switches the outflow destination of the flush water flowing through the sanitary washing water supply pipe 61 to one of a plurality of water outlets (not shown) that the nozzle 65 has.

[0055] Nozzle 65 discharges cleaning water from hot water storage tank 63 toward the private parts (human private parts) of a user seated on the toilet seat. A drive source such as a motor (not shown) is connected to nozzle 65, and by driving the motor, nozzle 65 is moved forward and backward between a position where it is advanced into bowl portion 21 of toilet body 20 and a position where it is retracted and stored in a storage case (not shown). When in the advanced position, nozzle 65 discharges cleaning water toward the user's private parts to clean them.

[0056] The toilet apparatus T, which includes the tank frame apparatus 1, flush toilet 2, and sanitary washing apparatus 3 described above, is equipped with a water supply pipe 70. The water supply pipe 70 may be, for example, a bendable hose pipe or flexible pipe, but is not limited to this.

[0057] As shown in Figures 1 to 3, the water supply pipe 70 connects the existing stop valve 15 to the newly installed flush toilet 2 and sanitary washing device 3, and supplies (supplies) flush water to the flush toilet 2 and sanitary washing device 3. In other words, the water supply pipe 70 supplies water to the water storage tank 41 of the newly installed flush toilet 2 and the newly installed sanitary washing device 3.

[0058] More specifically, the upstream end 70a of the water supply pipe 70 is connected to the existing stop valve 15. Specifically, the upstream end 70a of the water supply pipe 70 is connected to the existing stop valve 15 in the existing tank 12a.

[0059] The water supply pipe 70 is also arranged to pass through the inside of the existing water supply path 12 located on the back side of the wall W. More specifically, the water supply pipe 70 is arranged to pass through the internal space 12x (see FIG. 3) of the existing tank 12a and the internal space 12y (see FIG. 3) of the existing water supply pipe 12b. The water supply pipe 70 is then taken out from the downstream end 12b4 of the existing water supply pipe 12b and arranged to extend toward the flush toilet 2.

[0060] Additionally, the downstream end 70b of the water supply pipe 70 is connected to the water supply section 30 of the flush toilet 2. Specifically, the downstream end 70b of the water supply pipe 70 is connected to the toilet-side water supply pipe 31 via the stop valve 32 of the water supply section 30.

[0061] Therefore, the replacement worker replacing the toilet apparatus T removes the wall-side lid portion Wb and lid portion 12a2, and accesses the stop valve 15 inside the existing tank 12a through the wall-side opening Wa of the wall portion W and the opening 12a1 of the existing tank 12a, and connects the upstream end 70a of the water supply pipe 70 to the stop valve 15. Next, the replacement worker passes the water supply pipe 70 through the existing water supply path 12 and removes it from the downstream end 12b4. The replacement worker then connects the downstream end 70b of the removed water supply pipe 70 to the water supply unit 30 of the flush toilet 2. This causes flush water to be supplied (supplied) to the flush toilet 2 and the sanitary flushing device 3.

[0062] In this manner, in this embodiment, the water supply pipe 70 is passed through the inside of the existing water supply path 12, so that the existing water supply path 12 functions as a sheath pipe for the water supply pipe 70.

[0063] Next, the position where the water supply pipe 70 is taken out from the existing water supply path 12 and extends towards the toilet body 20 will be described. As shown in Figure 2, the water supply pipe 70 is taken out from the existing water supply path 12 at a position corresponding to the center or approximately the center of the toilet body 20 in the left-right direction (X-axis direction), and is arranged so as to extend towards the inside of the toilet body 20. In detail, the water supply pipe 70 is arranged so as to extend towards the inside of the toilet body 20 from a central region (region defined by width B in Figure 2) that includes the center of the toilet body 20 in the left-right direction.

[0064] The width B in the left-right direction of the central region can be set arbitrarily. As an example, the widths D on both the left and right sides from the center line (perpendicular line) C passing through the center of the toilet body 20 are set to 15 mm or less than 15 mm. In other words, the width B in the left-right direction of the central region is set to 30 mm or less than 30 mm. The specific values ​​of the widths B and D mentioned above are merely examples and are not limiting.

[0065] The toilet apparatus T according to this embodiment also includes a packing 80, as shown in Fig. 3. The packing 80 is shown by imaginary lines in Fig. 1 and is omitted from Fig. 2. The packing 80 will now be described with reference to Fig. 4. Fig. 4 is an enlarged perspective view of the vicinity of the packing 80.

[0066] 3 and 4, the packing 80 is attached to the existing water supply path 12. For ease of understanding, the existing water supply path 12 is shown by imaginary lines in FIG.

[0067] The packing 80 is made of, for example, resin and is a sealing member configured from an elastic member. The packing 80 is formed in a disk shape with an insertion hole 80a formed in the center. The water supply pipe 70 is inserted through the insertion hole 80a of the packing 80. In other words, the packing 80 is attached to the outer peripheral surface 70c of the water supply pipe 70. The insertion hole 80a of the packing 80 and the water supply pipe 70 are tightly attached to each other so as to be liquid-tight, but the present invention is not limited to this.

[0068] The packing 80 attached to the water supply pipe 70 is attached to the existing water supply path 12. Specifically, the packing 80 is attached to the downstream opening 12b5 of the existing water supply path 12. More specifically, the packing 80 is attached so as to block the downstream opening 12b5 of the downstream end 12b4 of the existing water supply pipe 12b.

[0069] This packing 80 can suppress water leakage from the existing water supply path 12. More specifically, the packing 80 can effectively suppress water leakage from the downstream opening 12b5 of the existing water supply path 12, which is prone to water leakage.

[0070] More specifically, as described above, flush water does not flow through the existing water supply path 12 itself, but water may accumulate, for example, due to a slight leak from the existing stop valve 15 or condensation water within the water supply path 12. In this embodiment, the gasket 80 described above is attached to the existing water supply path 12, so that water accumulated in the existing water supply path 12 can be prevented from leaking into the toilet room.

[0071] Although the above example shows the case where packing 80 is attached to downstream opening 12b5 of existing water supply path 12, the attachment position is not limited to this. That is, packing 80 may be attached to any position in existing water supply path 12, such as the connection between existing tank 12a and existing water supply pipe 12b.

[0072] As described above, the toilet apparatus T according to the embodiment comprises a toilet body 20, a water supply unit 30, and a water supply pipe 70. The toilet body 20 has a bowl 21 that receives waste. The water supply unit 30 includes a water storage tank 41 that is provided in the toilet body 20 and stores flush water to be supplied to the bowl 21. The water supply pipe 70 has an upstream end 70a connected to an existing stop valve 15 located on the back side of the wall W to which the toilet body 20 is attached, and passes through an existing water supply path 12 located on the back side of the wall W, and has a downstream end 70b connected to the water supply unit 30.

[0073] In this way, the toilet apparatus T includes a water supply pipe 70 having an upstream end 70a connected to the existing stop valve 15, passing through the existing water supply path 12, and having a downstream end 70b connected to the water supply unit 30. This allows the existing stop valve 15 to be easily connected to the water supply unit 30 for the new toilet apparatus T, regardless of the location of the existing water supply path 12. Furthermore, because the water supply pipe 70 passes through the existing water supply path 12 located behind the wall W, the existing water supply path 12 can function as a sheath pipe for the water supply pipe 70. Therefore, when replacing the toilet apparatus, there is no need to destroy the wall W to remove the water supply path 12 or to install new water supply piping for the new toilet apparatus T, and the toilet apparatus can be easily replaced. In this way, in this embodiment, the toilet apparatus T can be easily replaced regardless of the type of existing toilet apparatus. Specifically, the flush toilet and sanitary washing device of the existing toilet device can be easily replaced with the new flush toilet 2 and sanitary washing device 3.

[0074] The water supply pipe 70 is arranged from a central region including the center of the toilet body 20 in the left-right direction toward the inside of the toilet body 20.

[0075] As a result, the water supply pipe 70 is arranged inside the toilet body 20 from a specified position (central area) in the toilet body 20, regardless of the extraction position of the existing water supply path 12, so that the water supply pipe 70 can be easily connected to the water supply section 30 of the toilet body 20.

[0076] The toilet also includes a sanitary washing device 3 that is installed on the toilet body 20 and that discharges washing water to wash the user's private parts, and a water supply pipe 70 supplies water to the water storage tank 41 and the sanitary washing device 3.

[0077] In this way, even when the toilet apparatus T is equipped with the sanitary washing apparatus 3, water is supplied to the sanitary washing apparatus 3 from the water supply pipe 70. Therefore, in this embodiment, an existing toilet apparatus can be easily replaced with a toilet apparatus T equipped with the sanitary washing apparatus 3.

[0078] In addition, the water supply section 30 is provided in the toilet body 20 and includes a toilet side water supply pipe 31 whose upstream end is connected to the water supply pipe 70 and whose downstream end is connected to the water storage tank 41, and the toilet side water supply pipe 31 branches and is connected to the sanitary cleaning device 3.

[0079] In this way, the toilet-side water supply pipe 31 of the water supply section 30, which is located downstream of the water supply pipe 70, is branched into a flow path for the water storage tank 41 and a flow path for the sanitary washing device 3, so it is possible to make the water supply pipe 70 a single pipe that is common (shared) for both the water storage tank 41 and the sanitary washing device 3. This makes it possible, for example, when replacing the toilet device T, to easily pass the water supply pipe 70 through the existing water supply path 12, making it easy to replace the toilet device T.

[0080] In the above, an example was shown in which the toilet apparatus T is equipped with the sanitary washing device 3, but the present invention is not limited to this, and the toilet apparatus T may be configured without the sanitary washing device 3.
