Best Mode for Carrying Out the Invention

[0022] Next, referring to the accompanying drawings, a flushing toilet device according to an embodiment of the present invention will be described. FIG. 1 is a perspective view of a flushing toilet device according to an embodiment of the present invention. FIG. 2 is a stepped cross-sectional view of the flushing toilet device according to an embodiment of the present invention as viewed from the side.

[0023] As shown in FIGS. 1 and 2, a flushing toilet device 1 according to an embodiment of the present invention includes a flushing toilet main body 2 having a bowl portion 2a and a drain trap pipe 2b, and a sanitary cleaning device 4 placed at a predetermined position at the rear part of the upper surface of the flushing toilet main body 2. Further, a toilet seat 6 and a toilet seat cover 8 are rotatably attached to the upper part of the main body portion 4a of the sanitary cleaning device 4.

[0024] As shown in FIG. 2, the flushing toilet main body 2 includes a bowl portion 2a for receiving dirt and a drain trap pipe 2b extending from the lower part of the bowl portion 2a. In addition, a rim water outlet 2c from which washing water is discharged is provided at the upper end portion of the bowl portion 2a. Further, in the present embodiment, the flushing toilet main body 2 is a full skirt type flushing toilet whose side surface is covered by a side wall surface 2g.

[0025] During toilet flushing, the washing water is discharged from the rim water outlet 2c through a water guiding path provided inside the flushing toilet main body 2. The washing water discharged from the rim water outlet 2c flows down while swirling in the bowl portion 2a, washes the dirt receiving surface of the bowl portion 2a, and is discharged to a drain pipe (not shown).

[0026] Note that the flushing toilet device 1 of the present embodiment is a wash-down type flushing toilet without a jet water outlet, but the present invention can be applied to any type of flushing toilet such as a siphon jet type flushing toilet with a jet water outlet.

[0027] The drain trap pipe 2b is a pipe that extends from the bottom of the bowl section 2a toward the rear of the toilet bowl body 2. The drain trap pipe 2b is composed of an upward pipe that extends diagonally upward from the bottom of the bowl section 2a and a downward pipe that connects to the downstream end of the upward pipe and extends toward the rear. The height of the top of this upward pipe determines the water level in the bowl section 2a. The water in the bowl section 2a seals the drain trap pipe 2b.

[0028] The sanitary cleaning device 4 has its main body 4a placed at a predetermined position on the rear of the upper surface 2d of the flush toilet body 2. As shown in Figure 2, when the sanitary cleaning device 4 is placed at the predetermined position, the rear end of its main body 4a is located in front of the rear end 2e of the flush toilet body 2. The main body 4a also contains a functional unit 4b, which consists of a nozzle that sprays cleaning water for cleaning the user's private parts, a drive mechanism that moves the nozzle forward and backward, and a pump that pressurizes the cleaning water to the nozzle (these are not shown).

[0029] Furthermore, a water supply pipe 10 that supplies cleaning water to the sanitary cleaning device 4 is connected to the functional unit 4b built into the main body 4a. This water supply pipe 10 is configured to supply cleaning water to the sanitary cleaning device 4 from inside the toilet body 2, through an upper opening 2f provided on the upper surface 2d of the toilet body 2. As shown in Figure 1, in the normal operating state of the toilet device 1, this upper opening 2f provided on the upper surface 2d of the toilet body 2 is covered and concealed by the main body 4a of the sanitary cleaning device 4 which is placed on top of the toilet body 2. Also, the water supply pipe 10 that supplies cleaning water to the sanitary cleaning device 4 is connected to the sanitary cleaning device 4 through the inside of the toilet body 2, and is therefore concealed in the normal operating state.

[0030] Furthermore, the water supply pipe 10 is provided with a shut-off valve 10a that switches the supply of washing water to the sanitary washing device 4 on and off. This shut-off valve 10a is provided to stop the supply of washing water to the sanitary washing device 4 during maintenance of the sanitary washing device 4, etc., and is open during the normal use of the flush toilet device 1. In this embodiment, the shut-off valve 10a of the water supply pipe 10 is also located inside the flush toilet body 2, and is therefore concealed during the normal use of the flush toilet device 1. As will be described later, during maintenance, etc., the shut-off valve 10a is exposed and made operable from the outside by moving the sanitary washing device 4 from the predetermined position shown in Figure 2.

[0031] In this embodiment, under normal use conditions, the shut-off valve 10a is located inside the toilet bowl body 2, below the upper surface 2d of the toilet bowl body 2. In contrast, as a modification, part or all of the shut-off valve 10a may be located above the upper surface 2d of the toilet bowl body 2. In this case, at least a part of the shut-off valve 10a is housed and concealed within the main body 4a of the sanitary cleaning device 4.

[0032] Next, the connection structure of the water supply pipe 10 to the sanitary cleaning device 4 will be described with reference to Figures 3 and 4. Figure 3 is a rear cross-sectional view showing an enlarged view of the connection between the sanitary cleaning device 4 and the water supply pipe 10. Figure 4 is a perspective view of the water supply pipe 10 housed inside the toilet bowl body 2, seen from the rear.

[0033] As shown in Figure 3, a functional unit 4b is housed inside the main body 4a of the sanitary cleaning device 4, and the water supply pipe 10 is connected to a water supply connection part 4c provided on the functional unit 4b via a flexible joint 12. That is, in this embodiment, a shut-off valve 10a is provided at the downstream end of the water supply pipe 10, and this shut-off valve 10a is connected to the flexible joint 12, which in turn is connected to the water supply connection part 4c of the functional unit 4b. In this embodiment, the shut-off valve 10a is provided at the downstream end of the water supply pipe 10, but the shut-off valve 10a may be provided in the middle of the water supply pipe 10.

[0034] The water supply pipe 10 is a flexible water supply hose connected to a water source such as a water supply system. The shut-off valve 10a is a faucet installed on the water supply pipe 10, and by turning the knob 10b, the supply of washing water to the sanitary washing device 4 can be switched on and off. During maintenance, etc., the shut-off valve 10a is pulled out from the top opening 2f of the toilet bowl body 2, and the knob 10b is turned to stop the supply of washing water to the sanitary washing device 4.

[0035] The flexible joint 12 is a joint consisting of a first pipe section 12a provided on the upstream side and a second pipe section 12b provided on the downstream side. As shown in Figure 3, both the first pipe section 12a and the second pipe section 12b are pipes bent in an L-shape. The upstream end of the first pipe section 12a is connected to the stopcock 10a of the water supply pipe 10, and the downstream end of the second pipe section 12b is connected to the water supply connection section 4c of the sanitary cleaning device 4.

[0036] Furthermore, the stopcock 10a and the first pipe section 12a are connected in a way that allows rotation around the axis of the pipe. Similarly, the downstream end of the first pipe section 12a and the upstream end of the second pipe section 12b, and the downstream end of the second pipe section 12b and the water supply connection section 4c are also connected in a way that allows rotation around the axis of the pipe. This allows the orientation of the downstream end of the water supply pipe 10 (stopcock 10a) to be freely changed. In this embodiment, the flexible joint 12 is composed of two L-shaped pipes, but a ball joint pipe fitting (not shown) or a flexible pipe (not shown) can also be used as the flexible joint 12.

[0037] Next, as shown in Figure 4, the water supply pipe 10 extends from bottom to top inside the toilet bowl body 2 (between the side wall surfaces 2g of the toilet bowl body 2), with its downstream end protruding upward from the top opening 2f of the toilet bowl body 2. This top opening 2f of the toilet bowl body 2 is an elongated oval-shaped hole that is long in the front-to-back direction of the toilet bowl body 2 (Figure 5), and is located on the side of the top surface 2d, behind the bowl portion 2a of the toilet bowl body 2.

[0038] Furthermore, as shown in Figure 4, a guide surface 14 is formed on the inside of the side wall surface 2g of the toilet bowl body 2 to guide the movement of the water supply pipe 10. In a top view, this guide surface 14 is located behind the top opening 2f of the toilet bowl body 2 and is an inclined surface facing backward. The water supply pipe 10 is pressed against this guide surface 14 due to the elasticity of the water supply pipe 10 itself. In other words, the water supply pipe 10 is routed inside the toilet bowl body 2 so as to be pressed against the guide surface 14. As will be described later, when pulling out the shut-off valve 10a of the water supply pipe 10 during maintenance, the water supply pipe 10 slides along the guide surface 14, guiding the movement of the water supply pipe 10 inside the toilet bowl body 2.

[0039] Next, with reference to Figure 5, the operation of the flush toilet device 1 according to an embodiment of the present invention will be explained. Figure 5 is a perspective view showing the state in which the top opening 2f and the shut-off valve 10a are exposed by rotating the sanitary cleaning device 4 on the toilet body 2 during maintenance of the flush toilet device 1.

[0040] First, as shown in Figure 1, during normal use of the flush toilet system 1, the upper opening 2f provided on the upper surface 2d of the flush toilet body 2 is covered by the sanitary washing device 4 placed on top of the flush toilet body 2, and the shut-off valve 10a of the water supply pipe 10 connected to the sanitary washing device 4 is also concealed. In this way, during normal use of the flush toilet system 1, the shut-off valve 10a is housed and concealed inside the flush toilet body 2 (between the side walls 2g on both sides), thus providing the user with an excellent aesthetic appearance.

[0041] Next, in order to stop the supply of cleaning water to the sanitary cleaning device 4 for maintenance or other purposes, the sanitary cleaning device 4 is rotated on the toilet bowl body 2, as shown in Figure 5, to expose the top opening 2f and the shut-off valve 10a. In this embodiment, since the top opening 2f is located on the left side of the top surface 2d of the toilet bowl body 2, the front ends of the toilet seat 6 and toilet seat cover 8 attached to the sanitary cleaning device 4 are moved to the right. As a result, the sanitary cleaning device 4 is rotated counterclockwise on the top surface 2d of the toilet bowl body 2 in a top view.

[0042] In this configuration, the left rear end of the main body 4a of the sanitary cleaning device 4 is moved toward the front of the flush toilet body 2, and the right rear end is moved toward the rear of the flush toilet body 2. Under normal use, the rear end of the main body 4a of the sanitary cleaning device 4 is positioned in front of the rear end 2e of the flush toilet body 2 (Figure 1). Therefore, even if the flush toilet device 1 is installed so that the rear end 2e of the flush toilet body 2 is in contact with the toilet room wall (not shown), the right rear end of the main body 4a of the sanitary cleaning device 4 will not interfere with the toilet room wall.

[0043] Furthermore, when the sanitary cleaning device 4 is rotated from the normal operating state shown in Figure 1 to the state shown in Figure 5, the direction in which the downstream end of the water supply pipe 10 is directed changes. However, since the water supply pipe 10 is connected to the water supply connection part 4c of the functional part 4b via the flexible joint 12, it can smoothly change direction in accordance with the movement of the sanitary cleaning device 4.

[0044] Furthermore, when the sanitary cleaning device 4 is rotated and the water supply pipe 10 is pulled out from the upper opening 2f of the toilet bowl body 2, the movement of the water supply pipe 10 is guided by the guide surface 14 inside the toilet bowl body 2. That is, when the water supply pipe 10 is pulled out, the water supply pipe 10 slides along the guide surface 14, so that the water supply pipe does not get caught inside the toilet bowl body 2 and the rotation of the sanitary cleaning device 4 is prevented.

[0045] As shown in Figure 1, by moving the sanitary cleaning device 4 from the normal operating state of the flush toilet device 1, the shut-off valve 10a of the water supply pipe 10 is exposed to the outside, as shown in Figure 5. Therefore, the worker can turn the knob 10b of the shut-off valve 10a to stop the water supply to the sanitary cleaning device 4. This allows the worker to perform repairs on the sanitary cleaning device 4. After the repairs are completed, the worker turns the knob 10b of the shut-off valve 10a again to restart the water supply to the sanitary cleaning device 4, and returns the sanitary cleaning device 4 to the designated position shown in Figure 1 to complete the maintenance work.

[0046] According to the flush toilet device 1 of the present invention, when the sanitary cleaning device 4 is placed at a predetermined position on the rear of the upper surface 2d of the flush toilet body 2, the shut-off valve 10a of the water supply pipe 10 is housed inside the flush toilet body 2. Therefore, the shut-off valve 10a is not exposed to the outside, and a flush toilet device 1 with superior aesthetics can be provided. Furthermore, by moving the sanitary cleaning device 4 from its predetermined position, the shut-off valve 10a is exposed, so the shut-off valve 10a can be operated from the outside during maintenance, etc.

[0047] Furthermore, according to the flush toilet device 1 of this embodiment, the upper opening 2f of the flush toilet body 2 is provided on the side of the upper surface 2d of the flush toilet body 2, and by rotating the sanitary washing device 4 on the flush toilet body 2, the upper opening 2f and the shut-off valve 10a are exposed. This makes it possible to operate the shut-off valve 10a without lifting the sanitary washing device 4 significantly from the flush toilet body 2, and thus maintenance can be easily performed.

[0048] Furthermore, according to the flush toilet device 1 of this embodiment, when positioned in a predetermined location, the rear end of the main body 4a of the sanitary washing device 4 is located in front of the rear end 2e of the flush toilet body 2. Therefore, even when the rear end 2e of the flush toilet body 2 is located near the wall of the toilet room, the sanitary washing device 4 can be easily rotated from its predetermined position on the flush toilet body 2.

[0049] Furthermore, in the flush toilet device 1 of this embodiment, since the water supply pipe 10 is connected to the water supply connection part 4c via the flexible joint 12, it is possible to prevent excessive force from being applied to the water supply connection part 4c and the water supply pipe 10 when moving the sanitary washing device 4 from a predetermined position, thereby preventing damage to the water supply connection part 4c and the water supply pipe 10.

[0050] Furthermore, according to the flush toilet device 1 of this embodiment, since the upper opening 2f of the flush toilet body 2 is an elongated hole that is long in the front-to-back direction of the flush toilet body 2, the shut-off valve 10a connected to the water supply pipe 10 extending from the rear of the flush toilet body 2 can be easily passed through, and the shut-off valve 10a can be exposed with a relatively small opening.

[0051] Furthermore, according to the flush toilet device 1 of this embodiment, a guide surface 14 is provided on the flush toilet body 2 to guide the movement of the water supply pipe 10 when the sanitary washing device 4 is moved from a predetermined position. This prevents the water supply pipe 10 from getting caught when the sanitary washing device 4 is moved, thus preventing the exposure of the shut-off valve 10a from being obstructed.

[0052] Furthermore, according to the flush toilet device 1 of this embodiment, the water supply pipe 10 is pressed against the guide surface 14 by the elasticity of the pipe itself inside the flush toilet body 2, so the water supply pipe 10 can be guided along the guide surface 14 without any special configuration, and the sanitary cleaning device 4 can be moved smoothly.

[0053] Although preferred embodiments of the present invention have been described above, various modifications can be made to the embodiments described above. In particular, in the embodiments described above, the shut-off valve was exposed by rotating the sanitary washing device on the toilet bowl body, but the present invention can also be configured so that the shut-off valve is exposed by sliding the sanitary washing device in the front-to-back direction or to the side.
