Summary of the Invention

Problems to be Solved by the Invention

[0005] The flush toilet device disclosed in Patent Document 1 is a floor-standing flush toilet device.

[0006] The inventor of the present case has earnestly studied whether the designability of the wall-mounted flush toilet device can be enhanced by devising the arrangement state of the operation part of the stop valve in the wall-mounted flush toilet device.

[0007] In addition, the inventor of the present case has found in the process of such studies that the operability of the stop valve can be enhanced by devising the arrangement state of the operation part of the stop valve in the floor-standing flush toilet device.

[0008] This invention was conceived based on the above-mentioned findings. The object of this invention is to provide a wall-mounted flush toilet device with a high aesthetic design. Another object of this invention is to provide a floor-standing flush toilet device with a high level of operability. [Means for solving the problem]

[0009] The present invention relates to a wall-mounted flush toilet device, comprising: a flush toilet body having a bowl and a drain trap pipe extending from the lower part of the bowl; a water supply channel through which flushing water for cleaning the bowl flows; a shut-off valve provided in the middle of the water supply channel; and an operating unit for manually operating the shut-off valve, wherein the operating unit is not located on the wall surface of the wall supporting the flush toilet device, nor on the floor surface located below the flush toilet device.

[0010] According to the present invention, the operating part of the shut-off valve is not located on the wall surface of the wall supporting the flush toilet device, nor on the floor surface located below the flush toilet device, thus providing extremely high aesthetic appeal and ease of cleaning.

[0011] Herein, the term "stopcock" in this specification refers to a component used to switch the supply / stop of primary water supplied from a water source, and is generally of a type that incorporates a filter (different from the ball valve used for Washlet®).

[0012] In the present invention, it is preferable that the toilet bowl body is made of ceramic and has a skirt portion that separates at least the front and left and right sides, and that the operating part is located inside the skirt portion and on either the left or right side with respect to the drain pipe, and is operable from the bottom side.

[0013] This allows for good accessibility and operability of the control panel from the bottom side.

[0014] Furthermore, in this case, it is even more preferable that the operating part is positioned to protrude further downward than the lower end of the skirt portion.

[0015] According to this, the visibility of the control panel from the side is improved without significantly compromising the design, thus enabling even better access and operability to the control panel.

[0016] Furthermore, in this case, it is preferable that a circumferential recess around the stopcock opens to the bottom side.

[0017] According to this design, a finger can be placed inside the surrounding recess, allowing the location of the shut-off valve to be easily reached by touch (improving operability).

[0018] Furthermore, in this case, it is preferable that reinforcing ribs protrude towards the bottom surface in areas away from the stopcock, and that the ribs are not provided in areas near the stopcock.

[0019] According to this, the location of the water stop valve can be easily reached by feel, using the presence or absence of reinforcing ribs as a clue (improving operability).

[0020] Alternatively, in the present invention, it is preferable that an openable and closable cover member is provided on the upper surface of the flush toilet body, and that the operating unit is located near the upper surface of the flush toilet body and is operable when the cover member is open.

[0021] This allows for good accessibility and operability of the control panel from the top side.

[0022] Furthermore, in the present invention, a portion of the water supply channel is a hose member extending from the connection point with the wall supporting the flush toilet device to the shut-off valve, and it is preferable that the shut-off valve and the hose member are attached to the flush toilet body at the time of product shipment.

[0023] According to this, since the implementation of the water supply line is completed simply by attaching the connection part to a wall (specifically, a predetermined connection part on the wall side), the workability is good.

[0024] Furthermore, in this case, the flush toilet device has an opening on the wall side, and the hose member is arranged to pass through the opening. When the flush toilet device is attached to the wall, it is preferable that the opening is closed by the wall.

[0025] According to this, there is no risk of the hose member interfering undesirably, and the flush toilet device can be attached to the wall as desired.

[0026] The present invention also relates to a floor-mounted flush toilet device, comprising a flush toilet main body having a bowl part and a drain trap pipe extending from the lower part of the bowl part, a water supply line through which washing water for washing the bowl part flows, a stop valve provided in the middle of the water supply line, an operation part for manually operating the stop valve, and an openable and closable cover member provided on the upper surface of the flush toilet main body. The operation part is arranged in the vicinity of the upper surface of the flush toilet main body and is operable when the cover member is in an open state.

[0027] According to this, good accessibility and operability from the upper surface side to the operation part can be realized.

Effect of the Invention

[0028] According to the present invention, the operation part of the stop valve is neither on the wall surface of the wall supporting the flush toilet device nor on the floor surface located below the flush toilet device, so the design property and cleaning property are extremely high.

[Modes for carrying out the invention]

[0030] In this specification, from the perspective of a user standing facing the front of a flush toilet, the near side is referred to as "front," the far side as "back," the left side as "left," and the right side as "right" (from the perspective of a user seated on the flush toilet, left and right will be reversed).

[0031] (Overall structure) Figure 1 is a perspective view showing a flush toilet 1 (flush toilet device) according to one embodiment of the present invention, Figure 2 is a plan view of the flush toilet 1 of this embodiment with the sanitary cleaning device removed, and Figure 3 is a schematic cross-sectional view along line III-III in Figure 2.

[0032] As shown in Figure 1, the flush toilet 1 of this embodiment is a wall-mounted flush toilet whose rear surface is fixed to a wall surface W. The flush toilet 1 comprises a ceramic toilet bowl body 2 (flush toilet bowl body), a tank device 4 for storing flushing water supplied to the toilet bowl body 2, and a sanitary cleaning device 6 placed on the upper surface of the toilet bowl body 2.

[0033] A water source (not shown), such as a water tap, is provided on the wall W, and this water source and the shut-off valve 8 are connected by a hose member 101 (see Figure 7). The shut-off valve 8 is a component for supplying or stopping the flow of flushing water from the water source to the toilet 1. The shut-off valve 8 is connected to the water supply valve device 32 of the toilet 1 (see Figures 4B and 5) via a water supply pipe 10 (usually made of steel pipe, but not limited to steel pipe).

[0034] In Figure 2, the rim outlet 22, rim water channel 24, upstream Z-type water channel 60 (upstream Z-type water channel), downstream Z-type water channel 28, and Z-type water channel connecting pipe 80 (connection section) are each indicated by dashed lines.

[0035] As shown in Figures 2 and 3, the toilet bowl body 2 has a bowl portion 12 for receiving waste, a drain trap pipe 14 connected below the bowl portion 12 for discharging waste, and a skirt portion 16 that surrounds the bowl portion 12 and the drain trap pipe 14 from the outside. A space S is formed between the bowl portion 12 and the drain trap pipe 14 and the skirt portion 16.

[0036] The bowl portion 12 has a bowl-shaped waste receiving surface 18 and a rim portion 20 formed along the upper edge of the bowl portion 12. Water is formed inside the bowl portion 12 (a water surface WS is formed).

[0037] The rim portion 20 has a rim outlet 22 for discharging cleaning water towards the rear, and a rim water channel 24 for guiding the cleaning water to the rim outlet 22. The rim outlet 22 is located near the center in the front-to-back direction on the right side of the bowl portion 12. The cleaning water discharged from the rim outlet 22 flows down the waste receiving surface 18 while swirling along the inner circumferential surface of the rim portion 20, cleaning the bowl portion 12.

[0038] Below the bowl section 12, a jet opening 26 is formed to discharge cleaning water toward the inlet 14a of the drain trap pipe 14. The jet opening 26 is positioned opposite the inlet 14a of the drain trap pipe 14, so that the cleaning water discharged from the jet opening 26 flows into the drain trap pipe 14 and activates the siphon effect.

[0039] Washing water is supplied to the jet outlet 26 via the upstream jet water conduit 60, the jet water conduit connecting pipe 80, and the downstream jet water conduit 28.

[0040] The drain trap pipe 14 has an inlet 14a connected to the bottom of the bowl section 12, an upward pipe 14b extending upward from the inlet 14a, a top 14c located at the highest point of the upward pipe 14b that defines the water level WS, and a rear pipe 14d extending almost horizontally backward from the top 14c. The rear pipe 14d of the drain trap pipe 14 is connected to a drain pipe (not shown) inside the wall W via a drain socket 30.

[0041] The sanitary washing device 6 includes a main body (not shown), a washing nozzle (not shown) that is movable back and forth from the main body, a toilet seat (not shown) that is rotatably attached to the main body, and a toilet seat cover that is rotatably attached to the main body so as to cover the toilet seat. The water supply pipe 10 connected to the shut-off valve 8 is connected to the main body of the sanitary washing device 6 via a water supply valve device 32 to supply washing water to be sprayed from the washing nozzle (see Figure 5).

[0042] Within the space S, the tank device 4 is housed in the portion surrounded by the skirt portion 16 below the bowl portion 12. Within the space S, in the portion rear of the bowl portion 12, a functional device for supplying flushing water stored in the tank device 4 to the toilet bowl body 2 is housed. This functional device may include, for example, a water supply valve device 32, a pump device 34, a switching valve device 36, and a control device 38. Furthermore, a base plate 40 is provided in the bottom opening 2a surrounded by the skirt portion 16 of the toilet bowl body 2. The aforementioned functional device is supported by this base plate 40.

[0043] Next, with reference to Figures 4A and 4B, the tank device 4 and functional devices housed in the space S within the toilet bowl body 2 will be described.

[0044] Figure 4A is a perspective view of the functional device of the flush toilet 1 of this embodiment, viewed from the upper left, and Figure 4B is a perspective view of the functional device of the flush toilet 1 of this embodiment, viewed from the upper right, at an angle. In Figure 4A, the direction in which the flushing water flows is indicated by an arrow.

[0045] The tank device 4 includes a water storage tank 42 (tank) for storing flushing water supplied to the toilet bowl body 2, a tank water supply unit 46 for allowing flushing water from the tank water supply pipe 44 to flow into the water storage tank 42, a float switch 48 for detecting the water level of flushing water stored in the water storage tank 42, and a fixing member 50 for fixing the tank device 4 to the bottom surface of the toilet bowl body 2.

[0046] The water storage tank 42 is formed in an L-shape in plan view, extending forward to the right of the drain trap pipe 14, then bending and extending to the left. The water storage tank 42 is a resin tank that stores cleaning water used for rim discharge and jet discharge, and is capable of storing a predetermined amount of cleaning water.

[0047] The tank water supply unit 46 is located on top of the water storage tank 42. The upstream side of the tank water supply unit 46 is connected to the tank water supply pipe 44, and the downstream side of the tank water supply unit 46 is connected to the water storage tank 42. The tank water supply unit 46 has a flow path formed inside to guide the cleaning water from the tank water supply pipe 44 towards the water storage tank 42.

[0048] The float switch 48 is designed to turn off when the water level in the water storage tank 42 falls below the shut-off level (full water level). Conversely, the float switch 48 turns on when the water level in the water storage tank 42 rises to the shut-off level, thereby closing the water supply valve device 32.

[0049] The water storage tank 42 is equipped with an overflow unit 62 for draining cleaning water outside the tank in the event that, for example, the float switch 48 malfunctions and the tank continues to supply water. The overflow unit 62 is connected to a drain socket 30, so that cleaning water overflowing from the water storage tank 42 is discharged into the drain socket 30 via the overflow unit 62.

[0050] The water supply valve device 32 includes a constant flow valve (not shown) for maintaining a constant flow rate of cleaning water, an on-off valve (not shown) located downstream of the constant flow valve for switching between supplying and shutting off cleaning water, and a solenoid valve (not shown) for driving the on-off valve. The upstream side of the water supply valve device 32 is connected to a water source (not shown) via a water supply pipe 10, a shut-off valve 8, and a hose member 101 (see Figure 7), while the downstream side of the water supply valve device 32 is connected to the sanitary cleaning device 6 via a water supply pipe 52 for the sanitary cleaning device, and also to the tank device 4 via a water supply pipe 44 for the tank. When the solenoid valve opens electromagnetically, the on-off valve opens, and cleaning water from the water source is supplied to the tank device 4 via the water supply pipe 44 for the tank.

[0051] The pump device 34 is a pressurized pump that pumps the flushing water stored in the tank device 4 to the toilet bowl body 2. The upstream side of the pump device 34 is connected to the tank device 4 via an upstream connecting pipe 54, and the downstream side of the pump device 34 is connected to the switching valve device 36 via a downstream connecting pipe 56. When the pump device 34 is operated, the flushing water stored in the tank device 4 is pumped under pressure and discharged from the rim outlet 22 and jet outlet 26, thereby flushing the toilet bowl.

[0052] The switching valve device 36 has a switching valve body (not shown) and switches the water supply channels that supply cleaning water supplied from the pump device 34 to the rim outlet 22 and the jet outlet 26, respectively. The upstream side of the switching valve device 36 is connected to the pump device 34 via a downstream connecting pipe 56. The downstream side of the switching valve device 36 is connected to the rim outlet 22 via a rim water supply pipe 58 and a rim water conduit 24, and is also connected to the jet outlet 26 via an upstream jet water conduit 60, a jet water conduit connecting pipe 80, and a downstream jet water conduit 28. When the switching valve body is closed, cleaning water from the pump device 34 is supplied to the rim outlet 22, and when the switching valve body is open, cleaning water from the pump device 34 is supplied to both the rim outlet 22 and the jet outlet 26.

[0053] The control device 38 is electrically connected to a remote control (not shown), a tank device 4 (particularly a float switch 48), a sanitary cleaning device 6, a water supply valve device 32, and a pump device 34, and is capable of sending and receiving various signals. When the control device 38 receives a cleaning start signal for a large or small cleaning from the remote control, it drives or stops the pump device 34 based on a pre-stored cleaning sequence.

[0054] Specifically, when the user operates the remote control, the control device 38 drives the pump device 34 to discharge the flushing water stored in the tank device 4 from the rim outlet 22 and the jet outlet 26. In addition, after flushing the toilet, the control device 38 opens the water supply valve device 32 to supply water to the tank, and closes the water supply valve device 32 when the float switch 48 detects that the tank is full.

[0055] The pipes connected to each element of the aforementioned functional device (water supply pipe 10, water supply pipe 44 for the tank, water supply pipe 52 for the sanitary washing device, upstream connecting pipe 54, downstream connecting pipe 56, water supply pipe 58 for the rim, upstream jet water conduit pipe 60, and jet water conduit connecting pipe 80) are flexible and can absorb manufacturing errors in the ceramic toilet bowl body 2. On the other hand, the downstream jet water conduit 28 is formed as part of the ceramic toilet bowl body 2.

[0056] Next, Figure 5 is a diagram showing the water supply channel through which the flushing water of the toilet bowl 1 of this embodiment flows.

[0057] As shown in Figure 5, the water supply channel for the flush toilet 1 consists of a stopcock 8, a water supply valve device 32, a tank device 4, a pump device 34, and a switching valve device 36, arranged from the upstream side.

[0058] First, cleaning water is supplied from the water source to the water supply valve device 32 via the stopcock 8 and the water supply pipe 10. The cleaning water supplied to the water supply valve device 32 is then supplied to the sanitary cleaning device 6 via the water supply pipe 52 for the sanitary cleaning device, and also to the tank device 4 via the water supply pipe 44 for the tank.

[0059] The cleaning water supplied to and stored in the tank device 4 is drawn up by the pump device 34 through the upstream connecting pipe 54 and the suction port 34a of the pump device water conduit 34p. The cleaning water thus drawn up is supplied to the switching valve device 36 via the downstream connecting pipe 56.

[0060] The cleaning water supplied to the switching valve device 36 is discharged from the rim outlet 22 via the rim water supply pipe 58 and the rim water conduit 24, and is also discharged as a jet from the jet outlet 26 via the upstream jet water conduit 60, the jet water conduit connecting pipe 80 and the downstream jet water conduit 28.

[0061] The cleaning water that overflows from the tank device 4 is discharged to the drain socket 30 via the overflow unit 62.

[0062] Next, Figure 6 is a cross-sectional view of the flush toilet 1 of this embodiment along a vertical plane extending in the front-rear direction through the pump device 34 and the upstream connecting pipe 54.

[0063] As can be seen from Figures 2, 4A, 4B, and 6, the upstream connecting pipe 54, the pump device 34, the downstream connecting pipe 56, the switching valve device 36, the upstream Z-type water conduit 60, and the Z-type water conduit connecting pipe 80 are all positioned to the left of the drain trap pipeline 14. The upstream portion of the downstream Z-type water conduit 28, which is connected to the upstream Z-type water conduit 60 by the Z-type water conduit connecting pipe 80, is also positioned to the left of the drain trap pipeline 14.

[0064] Furthermore, as can be seen from Figures 4A, 4B, and 6, in the area A to the left of the drain trap pipe 14 (the area not occupied by the L-shaped water storage tank 42), the functional devices, the pump device 34, the control device 38, and the switching valve device 36, are arranged in that order so as to be in a nearly straight line vertically.

[0065] Furthermore, in area A, an upstream connecting pipe 54 connecting the tank device 4 and the pump device 34, a downstream connecting pipe 56 connecting the pump device 34 and the switching valve device 36, and an upstream jet water conduit 60 (upstream jet water conduit) are arranged.

[0066] The pump device 34 is positioned so as to face the rear wall 72b of the left side region 72 of the water storage tank 42 in the front-rear direction. The pump device 34 is also positioned so as to be at approximately the same height as the upper wall 72a of the left side region 72.

[0067] The outflow pipeline 72c, which extends rearward from the left-side area 72 of the water storage tank 42, is a pipeline that draws up cleaning water from the water storage tank 42 through the suction port 72e, and its outlet 72d is connected via the upstream connecting pipe 54 to the suction port 34a of the pump device water conduit 34p of the pump device 34.

[0068] The control device 38 is fixed to the upper surface of the pump device 34, and the switching valve device 36 is fixed to the upper surface of the control device 38. The downstream connecting pipe 56 that connects the pump device 34 and the switching valve device 36 is located near the control device 38 and is arranged in parallel with the control device 38.

[0069] The pump device 34, the control device 38, and the switching valve device 36 are arranged such that, in a plan view, at least a portion of each overlaps the others. The switching valve device 36 is located inside the outer periphery of the pump device 34 and the outer periphery of the control device 38 in a plan view. The downstream connecting pipe 56 is located inside the outer periphery of the pump device 34 in a plan view.

[0070] (Characteristic structure) Figure 7 is a side perspective view of the toilet bowl body 2 showing the position of the shut-off valve 8. As shown in Figure 7, the shut-off valve 8 in this embodiment is attached to the toilet bowl body 2 and has an operating part 8a for manually operating the shut-off valve 8.

[0071] More specifically, as shown in Figure 7, the stopcock 8 of this embodiment is a roughly cylindrical member fixed in a roughly vertical direction, with the connection part to the hose member 101 located at the upper end, the connection part to the water supply pipe 10 located in the middle, and the operating part 8a located at the lower end. The operating part 8a can be operated from the bottom side.

[0072] Therefore, as is clear from Figure 7, the operating unit 8a is not located on the wall surface W of the wall supporting the flush toilet 1 (flushing toilet device), nor on the floor surface located below the flush toilet 1.

[0073] Figure 8 is a downward perspective view of the flush toilet 1 showing the position of the shut-off valve 8. As shown in Figure 8, the shut-off valve 8 is positioned in the horizontal plane between the upstream connecting pipe 54 and the drain trap pipe 14. (That is, the operating part 8a of the shut-off valve 8 is located inside the skirt portion 16 and to the left of the drain trap pipe 14.)

[0074] Next, Figure 9 is a schematic cross-sectional perspective view of the flush toilet 1 of this embodiment, along a vertical plane extending in the front-rear direction, passing near the inner edge of the resin cover 102 supporting the stopcock 8, and Figure 10 is a perspective view showing the stopcock 8 as seen from the base plate 40 side.

[0075] As shown in Figures 9 and 10, in the base plate 40 of this embodiment, a circumferential recess 40a opens to the bottom side around the stopcock 8. The recess 40a in this embodiment is a circular recess with a diameter of approximately 8.5 cm and a depth of approximately 2.5 cm (the diameter of the operating part 8a of the stopcock 8 is approximately 3 cm, and the recess 40a is positioned concentrically with it).

[0076] Furthermore, as shown in Figure 9, in areas away from the stopcock 8, the reinforcing rib 40b protrudes towards the bottom surface, while in areas near the stopcock 8, the rib 40b is not provided.

[0077] Figure 11 is a bottom view of the base plate 40 showing an example of a division between an area where it is preferable to provide ribs 40b and an area where it is not preferable to provide ribs 40b.

[0078] In the example shown in Figure 11, the region β to the left of the operating section 8a, corresponding to the front-to-back length L including the operating section 8a, is designated as a region where it is undesirable to provide the rib 40b, while the region α forward of region β and the region γ backward of region β are designated as regions where it is preferable to provide the rib 40b. Furthermore, in the example shown in Figure 11, the region to the right of the operating section 8a also has a rib 40b (although a pattern in which the rib 40b is not provided in this region is also a preferred example). The front-to-back length L is, for example, 8.5 cm. The shape and arrangement pattern of the rib 40b are not particularly limited, but for example, its protruding height is about 10 mm.

[0079] Figures 12 and 13 are perspective views showing the resin cover 102 that supports the stopcock 8. As shown in Figures 12 and 13, the resin cover 102 is a trough-shaped member with a U-shaped cross-section and is installed to cover a portion of the upper part of the stopcock 8 (including the connection part with the water supply pipe 10 and the part above it, but not the connection part with the hose member 101).

[0080] A resin hinge 103, integrally formed with the resin cover 102, is provided on the upper part of the resin cover 102 (the part located above the connection between the stopcock 8 and the water supply pipe 10). The engaging portion 103e (fitting hole) at the tip of the resin hinge 103 and the corresponding engaged portion 102e (fitting projection) provided on the upper part of the resin cover 102 engage with each other.

[0081] Furthermore, an L-shaped mounting flange 102a extends from a position below the engaged portion 102e. The L-shaped mounting flange 102a extends laterally and then bends into a roughly L-shape when viewed from above.

[0082] Furthermore, two parallel, straight mounting flanges 102b extend from a position corresponding to the rear side of the connection between the stopcock 8 and the water supply pipe 10.

[0083] The shut-off valve 8 is supported by the toilet bowl body 2 when these mounting flanges 102a and 102b are fixed to the toilet bowl body 2. The mounting flanges 102a and 102b may be fixed directly to the toilet bowl body 2, or they may be fixed indirectly to the toilet bowl body 2 by being fixed to other elemental members fixed to the toilet bowl body 2.

[0084] Next, Figure 14 is a perspective view showing the rear opening 2c of the toilet bowl body 2. As shown in Figure 14, the toilet bowl body 2 of the flush toilet 1 in this embodiment has a rear opening 2c (opening) on ​​the wall side. The hose member 101 is arranged to pass through the rear opening 2c. When the flush toilet 1 is attached to the wall surface W, the rear opening 2c is closed by the wall surface W.

[0085] As explained with reference to Figure 7, the hose member 101 in this embodiment is a hose member that extends from the connection part of the water supply fitting on the wall supporting the flush toilet 1 to the shut-off valve 8. The shut-off valve 8 and the hose member 101 are attached to the flush toilet 1 side at the time of product shipment.

[0086] (Effects due to distinctive configuration) As described above, with the flush toilet 1 of this embodiment, the operating part 8a of the shut-off valve 8 is not located on the wall surface W supporting the flush toilet 1, nor on the floor surface located below the flush toilet 1, thus providing extremely high aesthetic appeal and ease of cleaning.

[0087] Furthermore, according to the flush toilet 1 of this embodiment, the toilet body 2 has a skirt portion 16 that separates at least the front and left and right sides, and the operating part 8a of the shut-off valve 8 is located inside the skirt portion 16 and on the left side (one example is either the left or right side) relative to the drain trap pipe 14, and is operable from the bottom side. This provides good accessibility and operability to the operating part 8a from the bottom side.

[0088] Furthermore, in the flush toilet 1 of this embodiment, a circumferential recess 40a is formed around the shut-off valve 8 and opens to the bottom. This allows a finger to be placed inside the circumferential recess 40a, making it easy to reach the location of the shut-off valve 8 by touch (improving operability).

[0089] Furthermore, in the flush toilet 1 of this embodiment, the reinforcing rib 40b protrudes towards the bottom surface in areas away from the shut-off valve 8, while the rib 40b is not provided in areas near the shut-off valve 8. As a result, the location of the shut-off valve 8 can be easily reached by touch using the presence or absence of the reinforcing rib 40b as a clue (improving operability).

[0090] Furthermore, in the flush toilet 1 of this embodiment, a portion of the water supply channel is a hose member 101 that extends from the connection point with the wall supporting the flush toilet 1 to the shut-off valve 8, and the shut-off valve 8 and the hose member 101 are attached to the flush toilet body 1 at the time of product shipment. As a result, the construction of the water supply channel is completed simply by attaching the connection point to the wall (specifically, to a predetermined connection point on the wall side), thus providing good workability.

[0091] Furthermore, according to the flush toilet 1 of this embodiment, the toilet body 2 has a rear opening 2c, and the hose member 101 is arranged to pass through the rear opening 2c. However, when the flush toilet 1 is mounted on a wall, the rear opening 2c is closed by the wall. As a result, the flush toilet 1 can be mounted on the wall as desired without the risk of the hose member 101 interfering undesirably.

[0092] (Variation 1) The flush toilet 1 according to the above-described embodiment is a siphon jet type flush toilet that discharges waste by generating a siphon action through jet water discharge. However, it is not limited to this form, and other forms may also be used, for example, a wash-down type flush toilet that washes away waste with the flowing water action caused by the difference in water pressure, or a siphon type flush toilet that discharges waste by generating a siphon action solely through rim water discharge.

[0093] (Modification 2) In the flush toilet 1 according to the above-described embodiment, the flushing water stored in the tank device 4 is supplied to the rim outlet 22 and the jet outlet 26. However, the invention is not limited to this configuration, and other configurations are also applicable, such as a configuration in which all the flushing water stored in the tank device 4 is discharged from the rim outlet 22.

[0094] (Variation 3) In the flush toilet 1 according to the embodiment described above, the lower end position of the operating part 8a of the shut-off valve 8 is roughly the same as the lower surface position of the base plate 40 (it is above the lower end of the skirt portion 16) (see Figures 7, 9, and 10).

[0095] However, the operating portion 8a of the stopcock 8 may be positioned to protrude further downward than the lower end of the skirt portion 16.

[0096] In this case, by adjusting the protrusion height to such an extent that it is not visible in the user's normal standing position (for example, to about 3 cm or less), the aesthetic appeal can be prevented from being significantly compromised, while the visibility of the operating part 8a is significantly improved when viewed from the side during maintenance, etc. This makes it possible to achieve even better accessibility and operability to the operating part 8a of the shut-off valve 8.

[0097] Figure 15 shows a side view of the toilet bowl body 2 corresponding to this modified example 3. In the example shown in Figure 15, the operating part 8a' of the shut-off valve 8' protrudes further downward than the lower end of the skirt portion 16.

[0098] (Modification 4) In the flush toilet 1 according to the above-described embodiment, the operating part 8a of the shut-off valve 8 is located on the base plate 40 side.

[0099] However, the operating part of the shut-off valve may be located near the top surface of the flush toilet (the toilet body).

[0100] Figure 16 shows a schematic side perspective view of the toilet bowl body 2 corresponding to this modified example 4. In the example shown in Figure 16, an openable and closable cover member 111 is provided on the top surface of the flush toilet bowl 1, and the operating part 8a" of the shut-off valve 8" can be operated from above when the cover member 111 is open.

[0101] In this configuration, good accessibility and operability of the operating section 8a'' from the top side can be achieved.

[0102] Furthermore, the features of this modified example 4 are not limited to wall-mounted flush toilets, but are also effective for floor-standing flush toilets.

[0103] Accordingly, the following invention is also proposed. That is, a further aspect of the present invention is a floor-standing flush toilet device comprising: a flush toilet body having a bowl portion and a drain trap pipe extending from the lower part of the bowl portion; a water supply channel through which flushing water for cleaning the bowl portion flows; a shut-off valve provided in the middle of the water supply channel; an operating unit for manually operating the shut-off valve; and an openable and closable cover member provided on the upper surface of the flush toilet body, wherein the operating unit is located near the upper surface of the flush toilet body and is operable when the cover member is open.
