Description

Technical Field

[0001] The disclosed embodiments relate to toilet apparatuses. Background Art

[0002] Various wall-mounted flush toilets have been proposed (see, for example, International Publication No. 2013 / 037488). In these toilets, a water supply path, including a water tank and a water supply pipe, is provided on the back side of the wall portion where the toilet body is mounted. Specifically, the water supply path is concealed on the back side of the wall portion, and flush water is supplied to the toilet body from this concealed water supply path.

[0003] However, existing technologies do not support replacement (renovation) of toilet fixtures. Specifically, the point at which the existing water supply path emerges from the wall toward the surface varies depending on the type of toilet fixture, or in other words, the manufacturer of the toilet fixture. Therefore, for example, when connecting the existing water supply path's point of exit to the water supply inlet of a newly installed toilet fixture via a connecting member, it is necessary to prepare connecting members corresponding to each of the multiple water supply path's point of exit, resulting in an increase in the number of components required for replacement.

[0004] Furthermore, in a newly installed toilet, for example, if the water tank is located on the toilet body, the existing water tank located on the back side of the wall is no longer necessary, and a water supply pipe for the newly installed toilet is required. Therefore, when replacing a toilet, one could consider destroying the wall, removing the existing water supply path including the water tank located on the back side of the wall, and then installing a new water supply pipe for the newly installed toilet. However, this would increase the labor required for the replacement process. Thus, the prior art still leaves room for improvement in terms of making it easier to replace toilets regardless of the type of existing toilet.

[0005] An object of one aspect of the embodiment is to provide a toilet apparatus that can be easily replaced regardless of the type of an already installed toilet apparatus. Summary of the Invention

[0006] A toilet device according to one embodiment of the present invention comprises: a toilet body having a bowl portion for receiving waste; a water supply portion including a water tank, the water tank being provided on the toilet body and storing cleaning water supplied to the bowl portion; and a water supply pipe, the upstream end of the water supply pipe being connected to a pre-installed water stopcock arranged on the back side of a wall portion on which the toilet body is assembled, the water supply pipe passing through the interior of a pre-installed water supply path arranged on the back side of the wall portion, and the downstream end of the water supply pipe being connected to the water supply portion.

[0007] Effects of the Invention

[0008] According to one aspect of the embodiment, the toilet apparatus can be easily replaced regardless of the type of the installed toilet apparatus. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] 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.

[0015] Reference Figure 1 and Figure 2 The toilet apparatus T according to the embodiment will be described. Figure 1 It is a perspective view of the toilet apparatus T according to the embodiment. Figure 2 This is a front view of the toilet device T according to the embodiment. Figure 1 、 Figure 2 and the following Figure 3 All the following are schematic diagrams.

[0016] In addition, Figure 1 For ease of description, mutually orthogonal X-axis, Y-axis, and Z-axis directions are defined, and a three-dimensional orthogonal coordinate system is illustrated in which the positive direction of the Z-axis is the vertical upward direction. In addition, in the following description, the positive direction of the X-axis is sometimes referred to as "left," the negative direction of the X-axis is sometimes referred to as "right," the positive direction of the Y-axis is sometimes referred to as "front," and the negative direction of the Y-axis is sometimes referred to as "back." Therefore, in the following description, the X-axis direction is sometimes referred to as the left-right direction, the Y-axis direction is sometimes referred to as the front-back direction, and the Z-axis direction is sometimes referred to as the up-down direction (vertical direction).

[0017] like Figure 1 and Figure 2 As shown, the toilet device T of the embodiment includes: a box frame device 1, a flush toilet 2, and a sanitary cleaning device 3 (only Figure 1 shown).

[0018] It should be noted that Figure 1 The toilet device T shown in FIG. 1 is a replacement (remodeled) toilet device. Here, the box frame device 1 is a device included in the toilet device before replacement, in other words, it is an existing device. The flush toilet 2 and sanitary cleaning device 3 are newly installed devices due to replacement.

[0019] The box frame device 1 is placed in the wall-back space of the bathroom. The wall-back space is the space on the opposite side of the bathroom interior where the flush toilet 2 is placed, separated by the bathroom wall W. The wall-back space is hidden by the wall W.

[0020] The box 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.

[0021] Frame 11 stands upright in the space behind the wall, supporting water supply path 12 and drain pipe 13. Specifically, frame 11 includes a plurality (here, two) of pillars 11a extending vertically upward from the floor of the space behind the wall, and a plurality (here, three) of beams 11b to 11d extending parallel to the floor of the space behind the wall and connecting the pillars 11a. It should be noted that the number of pillars 11a and beams 11b to 11d included in frame 11 is not limited to the example above.

[0022] The beam portion 11b is provided at the upper section of the frame 11. The beam portion 11c is provided at the middle section of the frame 11, and the beam portion 11d is provided at the lower section of the frame 11. The rear end portion of the flush toilet 2 is fixed to the beam portion 11c via the wall portion W. Specifically, a plurality of mounting holes 14 are formed in the beam portion 11c, and rod-shaped supporting members (not shown) are inserted into the mounting holes 14. The supporting members protrude into the interior of the bathroom via the wall portion W. On the other hand, an insertion hole is provided at the rear end portion of the flush toilet 2 at a position corresponding to the mounting hole 14 of the beam portion 11c. By inserting the supporting member into the insertion hole, the flush toilet 2 is supported by the frame 11 and assembled to the wall portion W.

[0023] The water supply path 12 is the path that supplies clean water to the flush toilet in the pre-replacement toilet installation. The water supply path 12 includes a water tank 12a and a water supply pipe 12b. It should be noted that since the water tank 12a and the water supply pipe 12b are pre-existing devices, the water tank 12a will be referred to as the "pre-existing water tank 12a," and the water supply pipe 12b will be referred to as the "pre-existing water supply pipe 12b." It should be noted that since the pre-existing water tank 12a and the pre-existing water supply pipe 12b are concealed by the wall W, they can also be referred to as a "hidden water tank" and a "hidden water supply pipe."

[0024] In the toilet device before replacement, a water storage tank 12a is provided to store flush water. In the toilet device before replacement, a water supply pipe 12b is provided to connect the existing water storage tank 12a and the flush toilet before replacement, and supply the flush water stored in the existing water storage tank 12a to the flush toilet.

[0025] The existing water stopper 15 is provided inside the existing water storage tank 12a. Therefore, the existing water stopper 15 is also arranged (hidden) on the back side of the wall portion W in the same manner as the existing water storage tank 12a. The water stopper 15 is connected to a water supply source A such as a water pipe (see Figure 3 It should be noted that, although an example is shown here in which the existing water stopcock 15 is provided inside the existing water storage tank 12a, the present invention is not limited thereto and may also be provided outside the existing water storage tank 12a.

[0026] It should be noted that in the replaced toilet device T, since a water storage tank 41 is provided on the toilet body side (see Figure 3 ), so no flush water is stored in the existing water tank 12a. Thus, since no flush water is stored in the existing water tank 12a, the water supply equipment such as the float valve installed in the existing water tank 12a (more precisely, the water supply equipment downstream of the water stopcock 15) is removed during replacement. In other words, while the water stopcock 15 remains installed in the existing water tank 12a, the water supply equipment downstream of the water stopcock 15 is removed.

[0027] Furthermore, an opening 12a1 for inspection work is formed on the side of the existing water tank 12a. Opening 12a1 is blocked by a cover 12a2. A wall-side opening Wa is formed in the wall portion W at a position corresponding to opening 12a1 of the existing water tank 12a. This opening Wa is blocked by a wall-side cover Wb. Therefore, a replacement operator can access the interior of the existing water tank 12a (e.g., the stopcock 15) through the wall-side opening Wa of the wall portion W and the opening 12a1 of the existing water tank 12a by removing the wall-side cover Wb and the cover 12a2.

[0028] The existing water supply pipe 12b includes an extension portion 12b1 and a curved portion 12b2. The extension portion 12b1 is configured such that its upstream end 12b3 is connected to the lower end 12a3 of the existing water storage tank 12a and extends downward from the lower end 12a3. The curved portion 12b2 is configured such that it is connected to the extension portion 12b1 and curves horizontally from the curved portion 12b2 toward the flush toilet 2. The curved portion 12b2 is inserted through the insertion hole 16 of the beam portion 11b, and the downstream end 12b4 of the curved 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.

[0029] It should be noted that in the replaced toilet apparatus T, since flush water is not stored in the existing water storage tank 12a, 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 interior of the existing water supply path 12, including the existing water storage tank 12a and the existing water supply pipe 12b. This will be described later.

[0030] The drain pipe 13 is a tubular member. The drain pipe 13 extends vertically upward from the ground in the space behind the wall and is a drainage flow path that opens horizontally toward the flush toilet 2. The drain pipe 13 is connected to the drainage elbow 24 of the flush toilet 2 described later (see Figure 3 ) to discharge the cleaning water from the flush toilet 2.

[0031] Next, refer to Figure 3 The flush toilet 2 and the sanitary cleaning device 3 will be described. Figure 3 It is a side sectional view of the toilet apparatus T in embodiment.

[0032] like Figure 3 As shown, the flush toilet 2 includes a toilet body 20 and a water supply unit 30. The flush toilet 2 is a so-called wall-mounted flush toilet in which the toilet body 20 is fixed to a wall surface WS of a wall portion W of a toilet.

[0033] The toilet body 20 is made of ceramic. It should be noted that the toilet body 20 is not limited to ceramic and can be made of, for example, resin or a combination of ceramic and resin. The toilet body 20 includes a bowl 21, a rim 22, a spout 23, and a drain elbow 24.

[0034] The bowl 21 is concave. It has a bowl surface 21a for collecting waste. A bowl rim 22 is located above the bowl 21. The bowl rim 22 is located at the upper edge of the bowl surface 21a. A water spout 23 is formed inside the bowl 21 to discharge wash water from the water tank 40 toward the bowl surface 21a within the bowl 21.

[0035] The drain elbow 24 forms part of the drainage path for draining waste from the bowl. One end of the drain elbow 24 is connected to the lower portion of the bowl 21, and the other end is connected to the drain pipe 13. It should be noted that one end of the drain elbow 24 serves as an inlet 24a of the drain elbow 24 and also serves as the inlet of the drainage path.

[0036] Specifically, the drain bend 24 includes a curved conduit 24b and a descending conduit 24c extending from the upstream side to the downstream side. The upstream inlet of the curved conduit 24b (inlet 24a of the drain bend 24) is connected to the lower portion of the bowl 21. A drainage flow path is formed, extending from the inlet 24a to the rear and lowermost end 24d, then rising to the rear and uppermost top 24e.

[0037] The downpipe 24c forms a drainage path that descends rearward and downward from the top 24e of the curved pipe 24b and connects to the drain pipe sleeve 26. It should be noted that a water seal (water seal WL) is formed in the upstream (front) area of ​​the top 24e of the curved pipe 24b. Furthermore, the inlet at the upstream end of the drain pipe 13, which faces the toilet body 20 (front), is connected to the outlet 24f at the downstream end of the drain elbow 24 via the drain pipe sleeve 26.

[0038] The water supply unit 30 includes a toilet-side water supply pipe 31, a stopcock 32, a valve unit 33, and a water tank 40. The toilet-side water supply pipe 31, stopcock 32, valve unit 33, and water tank 40 are provided on the toilet body 20. The stopcock 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 the water supply pipe 70 via the stopcock 32, but this will be described later.

[0039] The toilet-side water supply pipe 31 branches at a bifurcation point P between the water stopcock 32 and the valve unit 33 into a first water supply pipe 31a and a second water supply pipe 31b. The first water supply pipe 31a supplies flush water to the water tank 41 (described later) of the flush toilet 2, while the second water supply pipe 31b supplies flush water to the sanitary cleaning device 3. Thus, the toilet-side water supply pipe 31 branches and connects to the sanitary cleaning device 3.

[0040] The valve unit 33 is provided in the first water supply pipe 31a. The valve unit 33 is driven by a control signal output from a toilet control device (not shown) to open and close the first water supply pipe 31a. For example, the valve unit 33 comprises a solenoid valve that opens and closes according to the control signal, switching between supplying and shutting off flush water to the water storage tank 41 (described later) of the flush toilet 2.

[0041] 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 water tank unit 40, and supplies flush water from the valve unit 33 to the water storage tank 41. Thus, 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).

[0042] The water tank unit 40 includes a water storage tank 41, a connecting portion 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 portion 42. The water storage tank 41 stores the cleaning 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 the cleaning water supplied to the bowl 21. The water storage tank 41 is assembled in the lower part of the toilet body 20. Thus, in the replaced toilet device T, the water storage tank 41 is provided in the toilet body 20. It should be noted that the position where the water storage tank 41 is provided in the toilet body 20 can be set arbitrarily.

[0043] The pressure pump 43 pressurizes the flush water from the water storage tank 41 and supplies it to the bowl 21 of the toilet body 20. The pressure pump 43 is assembled inside the toilet body 20. As the pressure pump 43 operates, the flush water stored in the water storage tank 41 is pressurized and flows through the connecting pipe 50 to be supplied to the toilet body 20. Furthermore, the flush water flows through the water conduit (not shown) provided in the toilet body 20 and is supplied from the water outlet 23 to the bowl 21 (more specifically, the bowl surface 21a).

[0044] An overflow pipe 44 is connected to the connection portion 42. When the flush water supplied to the water storage tank 41 exceeds a predetermined water level, the overflow pipe 44 discharges the flush water toward the bowl 21 of the toilet body 20.

[0045] The sanitary cleaning device 3 is a device that cleans the user's local area by discharging cleaning water. The sanitary cleaning device 3 is provided on the toilet body 20, and more specifically, on the upper surface of the toilet body 20 (see Figure 1 ).

[0046] The sanitary washing device 3 includes a sanitary washing water supply unit 60. The sanitary washing water supply unit 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. It should be noted that the sanitary washing water supply unit 60 may be configured to include other components such as a vacuum interrupter in addition to the valve unit 62 and the like.

[0047] The upstream end of the sanitary washing water supply pipe 61 is connected to the second water supply pipe 31b that branches off from the toilet-side water supply pipe 31. It should be noted that while the sanitary washing water supply pipe 61 and the second water supply pipe 31b are shown as separate connections here, this is not limiting and the sanitary washing water supply pipe 61 and the second water supply pipe 31b may also be integrated.

[0048] The sanitary washing water supply pipe 61 is provided with a valve unit 62, a hot water storage tank 63, a switching valve 64, and a nozzle 65 from the upstream side to the downstream side. The valve unit 62 is driven by a control signal output from the control device (not shown) of the sanitary washing device 3 to open and close the sanitary washing water supply pipe 61. For example, the valve unit 62 includes a solenoid valve that can be opened and closed according to the control signal to switch the supply and stop of washing water to the nozzle 65.

[0049] Hot water storage tank 63 stores the washing water supplied to nozzle 65. A heater (not shown) is provided in hot water storage tank 63, which heats the stored washing water. Switching valve 64 is driven by a control signal output from the controller (not shown) of sanitary washing device 3 to switch the outflow destination of the washing water flowing through sanitary washing water supply pipe 61. Specifically, switching valve 64 switches the outflow destination of the washing water flowing through sanitary washing water supply pipe 61 to any of the multiple water outlets (not shown) provided by nozzle 65.

[0050] The nozzle 65 discharges the cleansing water from the hot water storage tank 63 toward the local area (body part) of the user seated on the toilet seat. A drive source, such as a motor (not shown), is connected to the nozzle 65. This motor drives the nozzle 65 forward and backward between a position within the bowl 21 of the toilet body 20 and a position within the housing (not shown) where it is retracted and stored. At the entry position, the nozzle 65 discharges cleansing water toward the user's local area, thereby cleaning the area.

[0051] The toilet apparatus T including the above-described tank frame device 1, flush toilet 2, and sanitary cleaning device 3 includes a water supply pipe 70. The water supply pipe 70 may be, for example, a bendable hose or flexible pipe, but is not limited thereto.

[0052] like Figures 1 to 3 As shown, the water supply pipe 70 connects the existing water stopcock 15 to the newly installed flush toilet 2 and sanitary cleaning device 3, supplying (supplying) cleaning water to the flush toilet 2 and sanitary cleaning 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 cleaning device 3.

[0053] In detail, the upstream end 70a of the water supply pipe 70 is connected to the existing stopcock 15. Specifically, the upstream end 70a of the water supply pipe 70 is connected to the existing stopcock 15 in the existing water storage tank 12a.

[0054] The water supply pipe 70 is disposed so as to pass through the interior of the existing water supply path 12 disposed on the back side of the wall portion W. Specifically, the water supply pipe 70 is disposed so as to pass through the interior space 12x (see FIG. 1 ) of the existing water storage tank 12a. Figure 3 ) and the internal space 12y (refer to Figure 3 Then, the water supply pipe 70 is arranged to be taken out from the downstream end 12b4 of the existing water supply pipe 12b and extended toward the flush toilet 2.

[0055] The downstream end 70b of the water supply pipe 70 is connected to the water supply unit 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 stopcock 32 of the water supply unit 30.

[0056] Therefore, the operator replacing the toilet apparatus T removes the wall-side cover Wb and the cover 12a2, accesses the water stopcock 15 within the existing water tank 12a via the wall-side opening Wa of the wall W and the opening 12a1 of the existing water tank 12a, and connects the upstream end 70a of the water supply pipe 70 to the water stopcock 15. The operator then passes the water supply pipe 70 through the interior of the existing water supply path 12 and removes it from the downstream end 12b4. The operator then connects the removed downstream end 70b of the water supply pipe 70 to the water supply unit 30 of the flush toilet 2. This supplies (or provides) flush water to the flush toilet 2 and the sanitary washing device 3.

[0057] As described above, in the present embodiment, by passing the water supply pipe 70 through the inside of the existing water supply path 12 , the existing water supply path 12 is made to function as a sheath for the water supply pipe 70 .

[0058] Next, the position where the water supply pipe 70 is taken out from the existing water supply path 12 and extends to the toilet body 20 will be described. Figure 2 As shown, the water supply pipe 70 is arranged to be 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 extend toward the inside of the toilet body 20. In detail, the water supply pipe 70 is arranged to be taken out from the central area (at the center of the toilet body 20) including the center in the left-right direction Figure 2 The area defined by the width B) extends toward the interior of the toilet body 20.

[0059] It should be noted that the width B of the central area in the horizontal direction can be set arbitrarily. As an example, the width D on each side of the central area from the centerline (perpendicular line) C passing through the center of the toilet body 20 is set to 15 mm or less. In other words, the width B of the central area in the horizontal direction is set to 30 mm or less. It should be noted that the specific values ​​of the widths B and D mentioned above are merely examples and are not limiting.

[0060] In addition, if Figure 3 As shown in FIG. 1 , the toilet device T of this embodiment includes a seal 80. Figure 1 The seal 80 is represented by an imaginary line in FIG. Figure 2 Here, also refer to Figure 4 The seal 80 will be described. Figure 4 It is an enlarged perspective view of the vicinity of the seal 80 .

[0061] like Figure 3 and Figure 4 As shown in FIG. 1 , the seal 80 is assembled to the water supply path 12. Figure 4 In the figure, for ease of understanding, the established water supply path 12 is represented by an imaginary line.

[0062] The seal 80 is made of, for example, a resin and is an elastic member. It is disc-shaped and has an insertion hole 80a formed in the center. The water supply pipe 70 is inserted through the insertion hole 80a of the seal 80. Specifically, the seal 80 is attached to the outer circumferential surface 70c of the water supply pipe 70. It should be noted that the insertion hole 80a of the seal 80 and the water supply pipe 70 are in close contact with each other in a liquid-tight manner, but this is not the only limitation.

[0063] The seal 80 attached to the water supply pipe 70 is attached to the existing water supply path 12. Specifically, the seal 80 is attached to the downstream opening 12b5 of the existing water supply path 12. More specifically, the seal 80 is attached so as to block the downstream opening 12b5 of the downstream end 12b4 of the existing water supply pipe 12b.

[0064] The seal 80 can suppress water leakage from the existing water supply path 12. More specifically, the seal 80 can effectively suppress water leakage from the downstream opening 12b5 of the existing water supply path 12, which is prone to water leakage.

[0065] Specifically, as described above, wash water does not flow through the existing water supply path 12 itself. However, water such as a small amount of water leaking from the existing water stopcock 15 or condensation water within the water supply path 12 may sometimes accumulate. In this embodiment, since the seal 80 described above is attached to the existing water supply path 12, the water accumulated in the existing water supply path 12 can be prevented from leaking toward the toilet.

[0066] It should be noted that, while the above description illustrates an example in which the seal 80 is mounted to the downstream opening 12b5 of the existing water supply path 12, the mounting position is not limited to this. Specifically, the seal 80 may be mounted at any location within the existing water supply path 12, such as the connection between the existing water storage tank 12a and the existing water supply pipe 12b.

[0067] As described above, the toilet apparatus T of the embodiment includes a toilet body 20, a water supply unit 30, and a water supply pipe 70. The toilet body 20 has a bowl 21 for receiving waste. The water supply unit 30 includes a water tank 41, which is provided on the toilet body 20 and stores wash water supplied to the bowl 21. The upstream end 70a of the water supply pipe 70 is connected to the existing water stopcock 15 located on the back side of the wall W to which the toilet body 20 is mounted. The water supply pipe 70 passes through the interior of the existing water supply path 12 located on the back side of the wall W, and the downstream end 70b of the water supply pipe 70 is connected to the water supply unit 30.

[0068] In this manner, the toilet apparatus T includes a water supply pipe 70 that connects to the existing water stopcock 15, passes through the interior of the existing water supply path 12, and has a downstream end 70b connected to the water supply unit 30. This makes it possible to easily connect the existing water stopcock 15 and the water supply unit 30 for the newly installed toilet apparatus T, regardless of the position from which the existing water supply path 12 is removed. Furthermore, since the water supply pipe 70 passes through the interior of the existing water supply path 12, which is arranged on the back side of the wall portion W, the existing water supply path 12 can function as a sleeve for the water supply pipe 70. Therefore, when replacing the toilet apparatus, there is no need to destroy the wall portion W to remove the water supply path 12 or to re-install a new water supply pipe for the newly installed toilet apparatus T, making the toilet apparatus easy to replace. Thus, 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 cleaning device of an existing toilet apparatus can be easily replaced with the newly installed flush toilet 2 and sanitary cleaning device 3.

[0069] Furthermore, the water supply pipe 70 is arranged from a central region of the toilet body 20 including the center in the left-right direction toward the interior of the toilet body 20 .

[0070] Therefore, regardless of the extraction position of the existing water supply path 12, the water supply pipe 70 can be installed from the specified position (center area) in the toilet body 20 to the inside of the toilet body 20, so the water supply pipe 70 and the water supply part 30 of the toilet body 20 can be easily connected.

[0071] The toilet apparatus T also includes a sanitary washing device 3 , which is provided in the toilet body 20 and washes the private parts of the user by discharging washing water. A water supply pipe 70 supplies water to the water tank 41 and the sanitary washing device 3 .

[0072] Thus, even when the toilet apparatus T includes the sanitary flushing device 3, water can be supplied from the water supply pipe 70 to the sanitary flushing device 3. Therefore, in the embodiment, an existing toilet apparatus can be easily replaced with a toilet apparatus T including the sanitary flushing device 3.

[0073] In addition, the water supply part 30 includes a toilet side water supply pipe 31, which is provided on the toilet body 20, its upstream end is connected to the water supply pipe 70, and its downstream end is connected to the water storage tank 41. The toilet side water supply pipe 31 is forked and connected to the sanitary cleaning device 3.

[0074] In this way, the flow path for the water storage tank 41 and the flow path for the sanitary washing device 3 are bifurcated at the toilet-side water supply pipe 31 of the water supply unit 30 located on the downstream side of the water supply pipe 70. This allows the water supply pipe 70 to be used as a single pipe for both the water storage tank 41 and the sanitary washing device 3. Consequently, when replacing the toilet device T, for example, the water supply pipe 70 can be easily passed through the interior of the existing water supply path 12, making it easy to replace the toilet device T.

[0075] In addition, in the above description, an example is shown in which the toilet apparatus T includes the sanitary washing device 3 , but the present invention is not limited thereto, and a configuration not including the sanitary washing device 3 may also be employed.

[0076] A toilet device according to one embodiment of the present invention comprises: a toilet body having a bowl portion for receiving waste; a water supply portion including a water tank, the water tank being provided on the toilet body and storing cleaning water supplied to the bowl portion; and a water supply pipe, the upstream end of the water supply pipe being connected to a pre-installed water stopcock arranged on the back side of a wall portion on which the toilet body is assembled, the water supply pipe passing through the interior of a pre-installed water supply path arranged on the back side of the wall portion, and the downstream end of the water supply pipe being connected to the water supply portion.

[0077] In this way, the toilet device has a water supply pipe that is connected to the existing water stopper at the upstream end, passes through the interior of the existing water supply path, and is connected to the water supply part at the downstream end. Therefore, regardless of the removal position of the existing water supply path, the existing water stopper and the water supply part for the newly installed toilet device can be easily connected. In addition, since the water supply pipe passes through the interior of the existing water supply path arranged on the back side of the wall portion, the existing water supply path can function as a sleeve of the water supply pipe. Therefore, when replacing the toilet device, there is no need to destroy the wall portion to remove the water supply path or to re-arrange the water supply pipe for the newly installed toilet device, and the toilet device can be easily replaced. In this way, in the embodiment, regardless of the type of the existing toilet device, the toilet device can be easily replaced.

[0078] Furthermore, the water supply pipe is arranged from a central region of the toilet body including the left-right center toward the interior of the toilet body.

[0079] Thus, regardless of the extraction position of the existing water supply path, the water supply pipe can be installed from a predetermined position (central area) in the toilet body to the inside of the toilet body, thereby making it easy to connect the water supply pipe and the water supply part of the toilet body.

[0080] Furthermore, the toilet apparatus includes a sanitary washing device provided on the toilet body and configured to wash the private parts of a user by discharging washing water. The water supply pipe supplies water to the water storage tank and the sanitary washing device.

[0081] Thus, even when the toilet device is equipped with a sanitary cleaning device, water can be supplied from the water supply pipe to the sanitary cleaning device. Therefore, in the embodiment, the existing toilet device can be easily replaced with a toilet device equipped with a sanitary cleaning device.

[0082] In addition, the water supply part includes a toilet side water supply pipe, which is arranged on the toilet body, its upstream end is connected to the water supply pipe, and its downstream end is connected to the water tank. The toilet side water supply pipe is forked and connected to the sanitary cleaning device.

[0083] In this way, the flow path for the water tank and the flow path for the sanitary washing device are bifurcated at the toilet-side water supply pipe of the water supply section located on the downstream side of the water supply pipe, so that the water supply pipe can be used as a common pipe for the water tank and the sanitary washing device. Therefore, when replacing the toilet device, for example, the water supply pipe can be easily passed through the interior of the existing water supply path, making it easy to replace the toilet device.

[0084] Furthermore, the toilet device includes a seal member that is attached to the already installed water supply path, thereby suppressing water leakage from the already installed water supply path.

[0085] Furthermore, the sealing member is mounted on the downstream opening of the existing water supply path. Thus, since the sealing member is mounted on the downstream opening of the existing water supply path which is prone to water leakage, water leakage from the downstream opening can be effectively suppressed.
