[0017] A flush toilet 1 according to one embodiment of the present invention will be described below with reference to the attached drawings. First, the basic structure of a flush toilet 1 according to one embodiment of the present invention will be explained with reference to Figures 1 to 3. Figure 1 is a perspective view showing a flush toilet according to one embodiment of the present invention, Figure 2 is a top view of the flush toilet according to one embodiment of the present invention with the sanitary cleaning device removed, and Figure 3 is a schematic cross-sectional view taken along line III-III in Figure 2. In Figure 2, the rim water channel, jet water channel, and jet water supply pipe are indicated by dotted lines. In this specification, when viewing a flush toilet from the front, the front side is referred to as "front," the back side as "rear," the left side as "left," and the right side as "right."

[0018] As shown in Figure 1, a flush toilet 1 according to one embodiment of the present invention is a wall-mounted flush toilet whose back surface is fixed to a wall W. The flush toilet 1 comprises a ceramic toilet bowl body 2, a tank device 4 for storing flushing water supplied to the toilet bowl body 2, and a sanitary washing device 6 placed on the top surface of the toilet bowl body 2. A shut-off valve 8 is provided on the wall W for supplying or stopping the flow of flushing water from a water source (not shown), such as a water supply, to the flush toilet 1. This shut-off valve 8 is connected to the flush toilet 1 via a water supply pipe 10.

[0019] 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 inside the toilet bowl body 2 between the bowl portion 12 and the drain trap pipe 14 and the skirt portion 16.

[0020] The bowl portion 12 comprises 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.

[0021] 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.

[0022] Below the bowl section 12, a jet outlet 26 is formed, which discharges cleaning water toward the inlet 14a of the drain trap pipe 14, and a jet water channel 28 is formed, which supplies cleaning water to the jet outlet 26. The jet outlet 26 is positioned opposite the inlet 14a of the drain trap pipe 14. The cleaning water discharged from the jet outlet 26 flows into the drain trap pipe 14 to activate a siphon effect.

[0023] One embodiment of the present invention describes a flush toilet 1 which is a siphon-jet type flush toilet that discharges waste by generating a siphon action through a jet of water. However, it is not limited to this form, and other forms may include, for example, a wash-down type flush toilet that washes away waste with the flowing 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.

[0024] The drain trap pipe 14 comprises 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, and a rear pipe 14d extending almost horizontally backward from this 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.

[0025] The sanitary cleaning device 6 comprises a main body (not shown), a cleaning nozzle (not shown) that is movable forward and backward 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 cleaning device 6 and supplies cleaning water to be sprayed from the cleaning nozzle. The sanitary cleaning device 6 is an example of an "electrical device" in this invention.

[0026] As shown in Figures 2 and 3, a space S is formed within the toilet bowl body 2 between the bowl portion 12 and the drain trap pipe 14 and the skirt portion 16. The tank device 4 is housed in the space S surrounded by the skirt portion 16 below the bowl portion 12 within the toilet bowl body 2. Functional devices for supplying flushing water to the toilet bowl body 2 are housed in the space S behind the bowl portion 12 within the toilet bowl body 2. These functional devices include, for example, a water supply valve device 32, a pump device 34, a switching valve device 36, and a control device 38. A base plate 40 is attached to the lower opening 2a surrounded by the skirt portion 16 of the toilet bowl body 2, and the above-mentioned functional devices are supported by this base plate 40.

[0027] The tank device 4 includes a water storage tank 42 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, and a float switch 48 for detecting the water level of the flushing water stored in the water storage tank 42. The water storage tank 42 is formed in an L-shape when viewed from above. The water storage tank 42 is positioned in the space S below the bowl portion 12 inside the toilet bowl body 2, extending forward to the right of the bowl portion 12, bending in front of the bowl portion 12, and extending to the left of the bowl portion 12. The float switch 48 is positioned above the water storage tank 42 and is set to an OFF state when the water level in the tank falls below the shut-off water level (full water level), opening the water supply valve device 32 to start water supply to the tank, and to an ON state when the water level in the tank rises and reaches the shut-off water level, closing the water supply valve device 32 to end water supply to the tank. The tank device 4 is an example of an "electrical device" in this invention.

[0028] 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 this on-off valve. The upstream side of the water supply valve device 32 is connected to a water source (not shown) via a stopcock 8 and a water supply pipe 10, while the downstream side of the water supply valve device 32 is connected to a sanitary cleaning device 6 via a water supply pipe 52 for the sanitary cleaning device, and also to a 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. The water supply valve device 32 is an example of an "electrical device" in this invention.

[0029] The pump device 34 is a pressurized pump that draws in the flushing water stored in the tank device 4 and pumps it to the toilet bowl body 2. The upstream side of the pump device 34 is connected to the tank device 4 via the upstream connecting pipe 54, and the downstream side of the pump device 34 is connected to the switching valve device 36 via the 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 the jet outlet 26, thereby flushing the toilet bowl. The pump device 34 is an example of an "electrical device" in this invention.

[0030] The switching valve device 36 includes a switching valve body (not shown) and switches the water supply channels that supply cleaning water 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, and the downstream side of the switching valve device 36 is connected to the rim water supply channel 24 via a rim water supply pipe 58 and to the jet water supply channel 28 via a jet water supply pipe 60. 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. The switching valve device 36 corresponds to an example of "electrical equipment" in the present invention.

[0031] The control device 38 is electrically connected to a remote control (not shown), a tank device 4 (float switch 48), a sanitary cleaning device 6, a water supply valve device 32, a pump device 34, and a switching valve device 36 by electrical wiring 70, enabling it to send and receive 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. Specifically, when the user operates the remote control, the control device 38 drives the pump device 34 to discharge the cleaning water stored in the tank device 4 from the rim outlet 22 and the jet outlet 26. The control device 38 also opens the water supply valve device 32 to supply water to the tank, and when the float switch 48 detects that the tank is full, it closes the water supply valve device 32 to stop the tank water supply.

[0032] Next, Figure 4 illustrates the water supply channel through which the flushing water of a flush toilet 1 according to one embodiment of the present invention flows. Figure 4 is a diagram showing the water supply channel through which flushing water flows for a flush toilet according to one embodiment of the present invention.

[0033] The water supply channel of the flush toilet 1 is configured, from upstream, with a stopcock 8, a water supply valve device 32, a tank device 4, a pump device 34, and a switching valve device 36. First, flushing 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 flushing water supplied to the water supply valve device 32 is supplied to the sanitary flushing device 6 via the sanitary flushing device water supply pipe 52, and also to the tank device 4 via the tank water supply pipe 44. The flushing water stored in the tank device 4 is drawn up by the pump device 34 via the upstream connecting pipe 54 and supplied to the switching valve device 36 via the downstream connecting pipe 56. The flushing 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 also discharged from the jet outlet 26 via the jet water supply pipe 60 and the jet water conduit 28. Furthermore, the cleaning water that overflows from the tank device 4 is discharged to the drain socket 30 via the overflow unit 62.

[0034] Next, with reference to Figures 5 to 7, the arrangement of the control device 38 in the rear space S inside the toilet bowl body 2 of a flush toilet 1 according to one embodiment of the present invention will be described in detail. Figure 5 is a perspective view of a functional device located in the rear space inside the toilet bowl of a flush toilet according to one embodiment of the present invention, Figure 6 is a schematic side view of the functional device located in the rear space inside the toilet bowl of a flush toilet according to one embodiment of the present invention, viewed from the right, and Figure 7 is a schematic rear view of the functional device located in the rear space inside the toilet bowl of a flush toilet according to one embodiment of the present invention, viewed from the rear.

[0035] As shown in Figure 5, a pump device 34 is fixed to the upper surface of a base plate 40 attached to the toilet bowl body 2. A control device 38 is fixed to the upper surface of the pump device 34. Furthermore, a switching valve device 36 is fixed to the upper surface of the control device 38. The pump device 34, control device 38, and switching valve device 36 are each fixed by fastening members 64, which are screws. Each fastening member 64 is positioned so that it can be fastened or unfastened from above the toilet bowl body 2. This allows the switching valve device 36, control device 38, and pump device 34 to be removed one by one from above the toilet bowl body 2 during maintenance.

[0036] As shown in Figures 5 to 7, the control device 38 is positioned near the upstream connecting pipe 54, pump device 34, downstream connecting pipe 56, switching valve device 36, and jet water supply pipe 60, which constitute the water supply channel through which the flushing water flows. Specifically, the control device 38 is positioned between the pump device 34 and the switching valve device 36, and is adjacent to both the pump device 34 and the switching valve device 36. In front of the control device 38, the downstream connecting pipe 56, which connects the pump device 34 and the switching valve device 36, is positioned. In addition, the upstream connecting pipe 54, which connects the tank device 4 and the pump device 34, is positioned below the front of the control device 38. Furthermore, the jet water supply pipe 60, which connects the switching valve device 36 and the jet water supply channel 28, is positioned above the front of the control device 38. In this way, because the control device 38 is positioned near the water supply channel, the control device 38 is compactly housed within the toilet bowl body 2.

[0037] As shown in Figure 7, the control device 38 is located near the drain trap pipe 14. Specifically, the control device 38 is located between the drain trap pipe 14 and the skirt portion 16. This allows the control device 38 to be compactly housed within the toilet bowl body 2.

[0038] Next, a control device 38 for a flush toilet 1 according to one embodiment of the present invention will be described in detail with reference to Figures 8 to 12. Figure 8 is a perspective view of a control device for a flush toilet according to one embodiment of the present invention, Figure 9 is a front view of a control device for a flush toilet according to one embodiment of the present invention, Figure 10 is a schematic cross-sectional view along line XX in Figure 8, Figure 11 is a schematic cross-sectional view along line XI-XI in Figure 8, and Figure 12 is a schematic cross-sectional view along line XII-XII in Figure 8.

[0039] As shown in Figure 8, the control device 38 includes a controller (not shown) that transmits and receives various signals, electrical wiring 70 that connects this controller to each device, and a cover member 72 that covers the controller from the outside.

[0040] The electrical wiring 70 includes an AC harness 70a and a DC harness 70b connected to the sanitary cleaning device 6, a pump harness 70c connected to the pump device 34, a solenoid valve harness (not shown) connected to the water supply valve device 32 (solenoid valve), a stepping motor harness (not shown) connected to the switching valve device 36, and an FWS harness (not shown) connected to the tank device 4 (float switch 48). In addition, the AC harness 70a and DC harness 70b connected to the sanitary cleaning device 6 are provided with a harness unit 70d for bundling multiple harnesses together.

[0041] The cover member 72 comprises a box-shaped upper cover portion 74 with an open bottom, and a plate-shaped lower cover portion 76 that covers the lower opening of the upper cover portion 74. The upper cover portion 74 comprises an upper wall 74a and a side wall 74b extending downward from the outer peripheral edge of the upper wall 74a. The upper cover portion 74 is joined to the lower cover portion 76 so as to cover the lower cover portion 76 from above. This prevents water from entering through the joint between the upper cover portion 74 and the lower cover portion 76.

[0042] A retaining portion 74c for holding the harness unit 70d is formed on the upper wall 74a of the upper cover portion 74. The retaining portion 74c extends upward from the upper wall 74a and is formed so that the harness unit 70d is inserted into it. The retaining portion 74c is located at the rear right corner of the upper wall 74a. The retaining portion 74c is formed so as to be able to hold the harness unit 70d so that the AC harness 70a and DC harness 70b extend toward the sanitary cleaning device 6. By holding the harness unit 70d in the retaining portion 74c, the electrical wiring 70 is wrapped around the control device 38, allowing the control device 38 and the electrical wiring 70 to move together as a single unit. In addition, two fixing portions 74d for fixing the switching valve device 36 are formed on the upper wall 74a of the upper cover portion 74. The switching valve device 36 is fixed to the control device 38 by inserting fastening members 64 into these fixing portions 74d.

[0043] The front side wall 74b of the upper cover portion 74 has a first opening 74e for the AC harness 70a to pass through, a second opening 74f for the DC harness 70b to pass through, and a third opening 74g for the pump harness 70c to pass through. The front side wall 74b also has a fixing portion 74h for fixing the control device 38 to the pump device 34. The control device 38 is fixed to the pump device 34 by inserting a fastening member 64 into this fixing portion 74h. The right and left side walls 74b of the upper cover portion 74 each have engaging portions 74i that engage with the projections 76a of the lower cover portion 76. The upper cover portion 74 and the lower cover portion 76 are joined together by the engagement of these engaging portions 74i of the upper cover portion 74 and the projections 76a of the lower cover portion 76.

[0044] As shown in Figure 9, the first opening 74e, the second opening 74f, and the third opening 74g are provided at the lower end of the front side wall 74b of the upper cover portion 74. The AC harness 70a and DC harness 70b exit the control device 38 from the first opening 74e and the third opening 74g, respectively, and then extend upward. Subsequently, the AC harness 70a and DC harness 70b are bundled together in a harness unit 70d and held by a retaining portion 74c. As a result, the AC harness 70a and DC harness 70b are arranged in a trap (U-shape).

[0045] The first opening 74e is located on the left side of the front side wall 74b, and the second opening 74f is located on the right side of the front side wall 74b. Because the first opening 74e and the second opening 74f are positioned at a distance from each other, the AC harness 70a and the DC harness 70b can be positioned at a distance from each other. This makes it possible to suppress noise that would occur if the AC harness 70a and the DC harness 70b were positioned in close proximity.

[0046] As shown in Figure 10, the upper cover portion 74 is provided with a first vertical path portion 78a extending vertically upward from the first opening 74e, a first horizontal path portion 78b extending horizontally backward from the upper end of the first vertical path portion 78a, a first expansion portion 78c expanding backward from the first horizontal path portion 78b, and a first entrance portion 78d formed on the bottom surface of the first expansion portion 78c. The AC harness 70a inserted through the first opening 74e is guided by the first vertical path portion 78a and the first horizontal path portion 78b and enters the control device 38 through the first entrance portion 78d. As a result, the AC harness 70a is arranged in a trap (U) shape. Since the first expansion portion 78c is formed behind the first horizontal path portion 78b, when the AC harness 70a bends downward, it bends gently without being sharply folded. The first enlarged section 78c is formed by the upper wall 74a protruding upward, and a space is formed in which the bent portion of the AC harness 70a is accommodated.

[0047] As shown in Figure 11, the lower cover portion 76 and the upper cover portion 74 are provided with a second horizontal path portion 80a extending horizontally rearward from the second opening 74f, a second expansion portion 80b expanding rearward from the second horizontal path portion 80a, a second vertical path portion 80c extending vertically upward from the second expansion portion 80b, and a second inlet portion 80d formed on the front surface of the second vertical path portion 80c. The DC harness 70b inserted through the second opening 74f is guided by the second horizontal path portion 80a and the second vertical path portion 80c and enters the control device 38 through the second inlet portion 80d. As a result, the DC harness 70b is arranged in a trap (U-shape). A second enlarged section 80b is formed between the second horizontal path section 80a and the second vertical path section 80c, so that when the DC harness 70b bends upward, it bends gently without being sharply folded. The second enlarged section 80b is formed by the lower cover section 76 protruding downward, and a space is formed to accommodate the bent portion of the DC harness 70b.

[0048] As shown in Figures 11 and 12, the lower cover portion 76 has a plurality of drainage holes 76c formed therein for draining water from inside the control device 38. One of the drainage holes 76c is provided in the second enlarged portion 80b of the lower cover portion 76. This ensures that even if water enters the control device 38, it can be drained out through the drainage hole 76c.

[0049] The following describes the operation and effects of the flush toilet 1 according to the above-described embodiment. First, according to the flush toilet 1 of one embodiment of the present invention, the cover member 72 of the control device 38 includes a first opening 74e and a second opening 74f through which the AC harness 70a and DC harness 70b pass, respectively, and a holding part 74c for holding the AC harness 70a and DC harness 70b. Since the AC harness 70a and DC harness 70b are held by the holding part 74c after they exit the control device 38 through the first opening 74e and the second opening 74f, the control device 38 and the AC harness 70a and DC harness 70b can be removed as a single unit. This makes it easier to remove the control device 38 and improves maintainability.

[0050] Furthermore, according to the flush toilet 1 of one embodiment of the present invention, the first opening 74e and the second opening 74f of the cover member 72 are provided below the cover member 72, and the holding portion 74c is provided above the cover member 72. This allows the AC harness 70a and DC harness 70b to be shaped like a trap, preventing water adhering to the AC harness 70a and DC harness 70b from traveling through each harness to the control device 38.

[0051] Furthermore, according to the flush toilet 1 of one embodiment of the present invention, the control device 38 is fixed to the toilet body 2 from above by fastening member 64 via pump device 34 and base plate 40, so that maintenance work can be performed from above the toilet body 2, thereby improving maintainability.

[0053] Furthermore, according to the flush toilet 1 of one embodiment of the present invention, the holding portion 74c of the cover member 72 is configured to hold the AC harness 70a and DC harness 70b so that the AC harness 70a and DC harness 70b extend toward the sanitary washing device 6, making it easier to connect the AC harness 70a and DC harness 70b to the sanitary washing device 6.

[0054] Furthermore, according to the flush toilet 1 of one embodiment of the present invention, the cover member 72 comprises an upper cover portion 74 and a lower cover portion 76, and the upper cover portion 74 is joined to the lower cover portion 76 so as to cover the lower cover portion 76, thereby preventing water from entering from the joint portion between the upper cover portion 74 and the lower cover portion 76.

[0055] Furthermore, according to the flush toilet 1 of one embodiment of the present invention, the lower cover portion 76 is formed with a drain hole 76c for draining water from the control device 38, so even if water enters the control device 38, it can be drained out through the drain hole 76c.

[0056] Furthermore, according to the flush toilet 1 of one embodiment of the present invention, the control device 38 is located near the water supply channel through which the flushing water flows (upstream connecting pipe 54, pump device 34, downstream connecting pipe 56, switching valve device 36, and jet water supply pipe 60), so the control device 38 can be compactly housed inside the toilet body 2.

[0057] Furthermore, according to the flush toilet 1 of one embodiment of the present invention, the control device 38 is located near the drain trap pipe 14, so the control device 38 can be compactly housed inside the toilet body 2.

[0058] While the sanitary cleaning device 6, tank device 4, water supply valve device 32, pump device 34, and switching valve device 36 have been described as examples of "electrical equipment" in the present invention, the invention is not limited to these and can be applied to other electrical equipment as well.
