A cover (for example, a rear cover 4 to be described later) and a piping cover (for example, a piping cover 5 to be described later) extending downward from one end of the rear cover to cover at least part of the piping along the side surface of the toilet body. and a flush toilet (for example, a flush toilet 100 described later).

It is preferable that the pipe cover is formed of a metal plate integrated with the rear cover, and bent and extended downward from the one end of the rear cover.

It is preferable that the piping cover is attached to the one end side of the rear cover and configured separately from the rear cover.

The pipe cover is preferably made of a flexible member made of resin.

It is preferable that the pipe cover covers a gap between a rear upper surface portion of the toilet body and the pipe.

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram showing a flush toilet 100 of the first embodiment. The flush toilet bowl 100 has a toilet body 110 , a pipe 2 , a seal portion 3 , a rear cover 4 and a pipe cover 5 .

The toilet body 110 is entirely made of ceramics. As shown in FIG. 1 , the toilet body 110 has a bowl portion 111 , a peripheral edge portion 112 , a rear upper surface portion 113 and a pipe through hole 114 .

The bowl portion 111 is arranged in front of the toilet body 110, and is a portion that is open at the top and recessed downward. A lower portion of the bowl portion 111 is connected to a drain port, and wash water is supplied to drain the dirt.

The peripheral edge portion 112 is the upper surface of the annular outer peripheral edge of the bowl portion 111, and a toilet seat (not shown) is placed thereon.

The rear upper surface portion 113 is a flat surface that is arranged at the rear of the toilet body 110 and extends rearward from the peripheral edge portion 112 . On the rear upper surface part 113, parts constituting a water supply part such as a water supply valve and a water supply tank (not shown) are installed.
In this specification, the front means the side of the flush toilet 100 on which the user sits, and the rear means the opposite side.

The pipe through-hole 114 is a hole penetrating the toilet body 110 from the rear toward the inside, and is connected to the pipe 2 described later. Two pipe through-holes 114 are formed according to the pipe 2 to be connected, and have a rim pipe through-hole 114a and a jet pipe through-hole 114b.

FIG. 2 is a side view of the flush toilet 100. FIG.
The pipe 2 is connected from the water supply portion to the toilet body 110 to supply flush water to the toilet body 110 . The pipe 2 has a rim pipe 21 and a jet pipe 22 .
The rim pipe 21 is a pipe that supplies flush water to the peripheral portion 112 of the toilet body 110 . As shown in FIG. 2, the rim pipe 21 extends rearward in the horizontal direction through the rim pipe through-hole 114a. The rim pipe 21 is sealed and fixed at the connecting portion with the rim pipe through-hole 114a.
The jet pipe 22 is a pipe that supplies flush water toward the bottom of the bowl portion 111 of the toilet body 110 . The jet pipe 22 is inserted through the jet pipe through-hole 114b and fixed. The jet pipe 22 is sealed inside the toilet body 110, and is not sealed around the jet pipe through-hole 114b.

The seal portion 3 seals the rim pipe 21 connected to the toilet body 110 . The seal portion 3 has a nut 31, a washer 32, a packing 33, a backup ring, and a retaining member (not shown).
The packing 33 is a rubber member in which two cylinders with different diameters are connected. The small-diameter cylindrical portion of the packing 33 is connected to the rim pipe through-hole 114a, and the large-diameter cylindrical portion is fitted in the rim pipe through-hole 114a so as to be exposed rearward.
The washer 32 is arranged on the rear surface of the packing 33 .
The nut 31 is inserted into the rim pipe 21 in a state in which the backup ring and the retaining member are arranged on the front side of the rim pipe through-hole 114a, and the packing 33 and the washer 32 are arranged on the rear side of the rim pipe through-hole 114a. It is fastened to the rear side of the through hole 114a. By tightening the nut 31, the packing 33, the washer 32, etc. are pressed, and the rim pipe 21 and the circumference of the rim pipe through-hole 114a are tightened by closely contacting the surface of the toilet bowl body 110 around the rim pipe through-hole 114a. A slight gap is sealed to form the seal portion 3 .

FIG. 3 is a perspective view of the rear cover 4 and the pipe cover 5 according to the first embodiment. In the first embodiment, the rear cover 4 and the pipe cover 5 are integral metal plates that are continuous with each other.

The rear cover 4 is placed and fixed on the upper surface of the rear upper surface portion 113 of the toilet body 110 . The rear cover 4 is a thin plate member that covers the rear upper surface portion 113 of the toilet body 110 . The rear cover 4 has a flat portion 41 , a pipe support portion 42 and a bead portion 43 .

The flat portion 41 is formed so as to be aligned so as to conform to steps and irregularities formed on the rear upper surface portion 113 . The plane portion 41 has an elongated shape, and the longitudinal direction is arranged along the width direction of the toilet body 110 (the direction substantially orthogonal to the front-rear direction).

The pipe support portion 42 is a portion that extends rearward continuously from the flat portion 41 and surrounds the rim pipe 21 and the jet pipe 22 . The pipe support portion 42 has three side wall portions 421 standing upward in the height direction from the flat portion 41 and an upper surface portion 422 connected to the three side wall portions 421. The upper surface portion 422 includes the rim pipe 21 and the jet. Two through holes 423 through which the pipe 22 can be inserted are formed.

The bead portion 43 is a portion press-formed so as to protrude from the flat portion 41 toward the back side. Since the bead portion 43 is formed, the plane portion 41 does not come into close contact with the rear upper surface portion 113 as it is. The height between the rear upper surface portion 113 and the flat surface portion 41 can be adjusted by adjusting the tightening strength of the screws when the flat portion 41 is fixed to the rear upper surface portion 113 with screws or the like. is configured to

The pipe cover 5 is provided at one longitudinal end of the rear cover 4 and extends downward. As shown in FIG. 3 , the pipe cover 5 extends downward from the edge of the flat portion 41 on the side where the pipe 2 is connected to the toilet body 110 and is bent substantially at right angles to the flat portion 41 . The pipe cover 5 has a substantially rectangular plate surface.

As shown in FIG. 2 , the pipe cover 5 extends along the side surface of the toilet body 110 and covers at least the upper side of the side portion of the rim pipe 21 . The pipe cover 5 is arranged rearwardly of the seal portion 3, and is arranged in a state where the seal portion 3 between the rim pipe through-hole 114a in the toilet body 110 and the rim pipe 21 is exposed. Since the seal portion 3 is exposed, it is easy to check if water leakage or the like occurs in a test or the like at the time of shipment.
A gap S1 is formed between the rim pipe 21 and the rear upper surface portion 113 of the toilet body 110 when viewed from the side. The pipe cover 5 covers the side portion of the rim pipe 21 about half of the upper surface side, and also covers the gap S1 between the rim pipe 21 and the rear upper surface portion 113 . Further, the piping cover 5 is arranged inside a side cover (not shown) attached to the side surface of the flush toilet 100 .

According to the first embodiment, the following effects are obtained.
In the first embodiment, the flush toilet 100 includes a pipe 2 that connects to a toilet body 110, a rear cover 4 that covers a rear upper surface portion 113 of the toilet body 110, and a toilet body extending downward from one end of the rear cover 4. and a pipe cover 5 that covers at least a part of the pipe 2 along the side of 110.
When the pipe cover 5 is not provided, the rim pipe 21 has a shape suitable for grasping and is connected at a position that is easy to grasp, so the installer grasps the rim pipe 21 and lifts the toilet body 110. or set it up. However, if the pipe cover 5 extends along the side surface of the toilet body 110 and covers at least the upper part of the side portion of the rim pipe 21, it becomes difficult for the installer to grasp only the rim pipe 21. On the other hand, since there is a predetermined height from the rear upper surface portion 113 of the toilet body 110 to the lower surface of the rim pipe 21, it is difficult to hold it with force. As a result, the builder will avoid grabbing the rim pipe 21 . As a result, force is less likely to be applied to the rim pipe 21, so damage to the seal portion 3 is prevented, and the seal portion 3 is well protected. In addition, since the seal portion 3 is protected, the workability of installing the flush toilet bowl 100 is improved.

In the first embodiment, the pipe cover 5 is formed of a metal plate integral with the rear cover 4 and bent from one end of the rear cover 4 to extend downward. By forming the rear cover 4 and the pipe cover 5 into an integral metal plate, the number of parts can be reduced and the manufacturing process can be facilitated. Moreover, since the rigidity of the rear cover 4 and the pipe cover 5 can be increased, the protection performance is also improved.

In the first embodiment, the pipe cover 5 is configured to cover the gap S1 between the rear upper surface portion 113 of the toilet body 110 and the rim pipe 21 . Since the pipe cover 5 covers the side of the gap S1 between the rim pipe 21 and the rear upper surface portion 113, the builder cannot put his hand into the gap S1. Moreover, in order to grasp the lower surface of the rim pipe 21 from the pipe cover 5, it is difficult to grasp the rear cover 4, the pipe cover 5, and the rim pipe 21, which are different members, straddling over and holding. Therefore, the builder comes to avoid grabbing the rim pipe 21, and the same effect as described above is achieved.

Fig. 4(a) is a perspective view of a rear cover and a piping cover of the second embodiment, and Fig. 4(b) shows a state in which the rear cover and the piping cover are attached to the toilet body. A flush toilet 100A according to the second embodiment will be described with reference to FIGS. 4(a) and 4(b). In the description of the second embodiment and thereafter, the description of the configuration common to the first embodiment is omitted.

The flush toilet 100A according to the second embodiment differs from the first embodiment in that the pipe cover 5A extends to the jet pipe 22 side. As shown in FIG. 4A, the piping cover 5A has a first cover portion 51 and a second cover portion 52. As shown in FIG. In the second embodiment, the rear cover 4, the first cover portion 51 and the second cover portion 52 are metal plates that are integrally formed continuously.

The first cover portion 51 is a substantially trapezoidal plate surface extending downward from one end of the rear cover 4 on the side of the toilet body 110 to which the pipe 2 is connected. The first cover part 51 has a larger area than the pipe cover 5 in the first embodiment.

The second cover portion 52 bends from the lower edge of the first cover portion 51 toward the inside in the width direction of the toilet body 110 . The second cover portion 52 is a substantially rectangular plate surface.

FIG. 4(b) shows a state of the toilet body 110 viewed from the rear side. As shown in FIG. 4B , the first cover portion 51 covers the side portion of the rim pipe 21 and also covers the gap S1 between the rear upper surface portion 113 and the rim pipe 21 . Since the first cover portion 51 has a substantially trapezoidal shape, the second cover portion 52 that is continuous with the first cover portion 51 is arranged along the inclination of the jet pipe 22 . The second cover portion 52 covers the gap S<b>2 between the rim pipe 21 and the jet pipe 22 .

According to the second embodiment, the gap S2 between the rim pipe 21 and the jet pipe 22 is also covered, and the surroundings of the rim pipe 21 and the jet pipe 22 are also covered together with the seal portion 3 . Therefore, the builder cannot touch the lower surface of the rim pipe 21 . In addition to being inclined along the inclination of the jet pipe 22, the second cover part 52 has a long distance from the edge of one end of the rear cover 4 to the lower end of the second cover part 52, which makes it easy to grasp. It is not. For this reason, the builder comes to avoid grasping both the rim pipe 21 and the jet pipe 22 . Therefore, there exists an effect similar to 1st embodiment.

FIG. 5(a) is a perspective view of the rear cover 4B and the pipe cover 5B of the third embodiment as seen from above, and FIG. 5(b) is a perspective view of the rear cover 4B and the pipe cover 5B as seen from below. It is a diagram. FIG. 6 is a rear view of the state in which the rear cover 4B and the pipe cover 5B are attached to the toilet body 110. As shown in FIG. A flush toilet 100B according to the third embodiment will be described with reference to FIGS. 5(a) to 6. FIG.

The third embodiment differs from the first and second embodiments in that a rear cover 4B and a pipe cover 5B are formed separately, and the pipe cover 5B is attached to one end side of the rear cover 4B. . As shown in FIG. 5(a), in the third embodiment, the rear cover 4 is a metal plate, but the pipe cover 5B is made of resin that is flexible enough to be deformed when the builder tries to grasp it. be.

As shown in FIG. 5(b), in the third embodiment, the rear cover 4B has an attachment portion 44 for the piping cover 5B. The mounting portion 44 is formed by bending downward one end of the flat portion 41 of the toilet body 110 to which the pipe 2 is connected. The mounting portion 44 is formed with a flat surface and has a small rectangular opening 44a.

As shown in FIGS. 5(a) and 5(b), the pipe cover 5B is formed in a substantially U-shape that opens toward the center in the width direction of the toilet body 110 and has three continuous sides. 53 , a side portion 54 and a curved portion 55 .

The upper surface portion 53 is a flat surface that is superimposed on one longitudinal end side of the flat portion 41 of the rear cover 4 .

The side surface portion 54 is a substantially trapezoidal plate surface that bends in a direction substantially perpendicular to the direction in which the upper surface portion 53 extends and extends downward. A lower edge of the side portion 54 is inclined along the inclination of the jet pipe 22 .

As shown in FIG. 5B, a pair of elastically deformable protrusions 541 protruding toward the toilet body 110 are formed on the back surface of the side surface portion 54 (the surface facing the toilet body 110). A claw portion 542 is formed on the distal end side of the projecting portion 541 so as to protrude outward from the facing projecting portions 541 . The projecting portion 541 is pushed into and engaged with an opening 44a formed in the mounting portion 44 of the rear cover 4B. The claw portion 542 protrudes outside the width of the opening 44a, thereby preventing the projection portion 541 from coming off after being inserted through the opening 44a.

The curved portion 55 is curved from the inclined lower edge of the side portion 54 toward the toilet bowl main body 110 in a substantially semicircular cross-sectional view in accordance with the cylindrical shape of the jet pipe 22 .

As shown in FIG. 6, the pipe cover 5B according to the third embodiment is attached to the side where the pipe 2 is connected to the toilet body 110 at one end of the rear cover 4B. The rear cover 4B covers the gap S1 between the rear upper surface portion 113 of the toilet body 110 and the rim pipe 21, and the side portion 54 covers the gap S2 between the rim pipe 21 and the jet pipe 22. Furthermore, a curved portion 55 that extends from the side surface portion 54 toward the inside of the toilet body 110 and curves to match the jet pipe 22 is arranged along the upper surface of the jet pipe 22 .

According to the third embodiment, since the pipe cover 5B is configured separately from the rear cover 4B and molded from resin, it can be manufactured at a low manufacturing cost and can be easily attached and detached. Moreover, the resin pipe cover 5B is flexible enough to be deformed when a worker tries to grasp it. If the grasped portion is deformed, the builder understands that the shape is not stable and avoids grasping it, so that the seal portion 3 can be effectively protected as a result.
The rigidity of the resin of the pipe cover 5B can be changed as appropriate, but by setting the rigidity to such an extent that it deforms when grasped, the installer can understand whether it has been grasped.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate.
For example, the pipe cover is not limited to the shape illustrated in the drawings. If the pipe cover extends downward from one end of the rear cover along the side surface of the toilet bowl body 110 and can cover at least part of the pipe 2, even if only part of the rim pipe 21 is covered, the rim pipe and the jet pipe may be covered, and the shape may be changed as appropriate. Also, the material, color, etc. of the pipe cover are not limited. The pipe cover may be transparent and flexible. Furthermore, when the rear cover and the pipe cover are configured separately, the connecting method and shape may be changed as appropriate.

Further, when the pipe cover is made of resin, it may be made of a material that has high rigidity and does not deform.
