Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor drainage type flush toilet, and more particularly, to facilitate connection between the drain port and the drain pipe on the building side when the toilet body is remodeled and replaced. Connection structure with the drain pipe.

[0002]

2. Description of the Related Art A floor drainage type flush toilet is one in which a drainage opening opened on the lower surface of the toilet body is received by a dedicated flange provided at the upper end of the drainage pipe on the building side and is connected in a sealed state. This is a conventional general construction structure.

On the other hand, in the case of remodeling in which the toilet bowl is replaced with a new one, the position of the drainage pipe on the building side is a fixed position in the toilet. If the specifications of the toilet bowl to be replaced are different from those previously installed, the position of the drainage port may change relative to the length of the toilet bowl body in the front-rear direction. For this reason, when installing the toilet bowl, when the position of the drain pipe on the building side is used as a reference, there are many cases where the toilet body interferes with the wall of the toilet or other equipment.

In order to eliminate such obstacles during installation,
For example, as described in Japanese Utility Model Laid-Open No. 2-144085, there is a connecting member capable of absorbing the positional deviation between the drainage pipe on the building side and the outlet of the toilet body.

This is provided with two members, a toilet-side connecting member connected to the outlet of the toilet body and a drain-side connecting member connected to the drainage pipe of the building, and the drain-side connecting member is in a substantially vertical posture on the toilet side. The connection member is connected in a substantially horizontal direction from the peripheral surface, and the tip is bent downward to connect to the drainage pipe. With such a connecting member, the horizontal portion of the drainage pipe-side connecting member can be cut off from the pipe end to adjust the length according to the displacement between the outlet and the drainage pipe. Even if the positional relationship between the outlet of the toilet body to be installed and the drainage pipe of the building changes depending on the site, the flow passage can be connected.

[0006]

However, when dealing with the case where the displacement distance between the discharge port and the drain pipe is large, it is necessary to lengthen the horizontal portion of the drain pipe side connecting member. For this reason, since the connecting member includes the horizontal portion whose one end is connected to the outlet side connecting member and the flange portion which is connected to the drain pipe, the member itself is considerably large. Then, in the horizontal portion having a larger axial length than the flange portion connected to the drain pipe side, the tip portion thereof is likely to be twisted and deformed. When such a twist occurs,
The construction will be accompanied by the misalignment of the core between the drain pipe side and the outlet side, and this will have a large effect on the seal. Further, since the connecting member is L-shaped, it becomes difficult to handle when cutting, the workability is poor, and the cut surface is easily bent.

Further, since it is necessary to cut off the horizontal portion of the drainage side connecting member during construction, it is possible that the dimensions may be erroneously cut during construction on site. Therefore, not only is the work of cutting off troublesome,
The quality of construction depends on how this cutting work is done, and the problem of workability remains.

Furthermore, since the connection member is connected to the drainage port and the drainage pipe by fixing and sealing with an adhesive, the adhesive work is troublesome, and if the application of the adhesive is insufficient, the sealing will be defective. There is also a high possibility that a water leakage accident will occur.

On the other hand, on the bottom side of the toilet body, the trap flow path extending from the ball portion is projected downward in a substantially U shape, and the space for piping is limited. Therefore, a large clearance cannot be secured between the connecting member and the bottom wall of the toilet body, and depending on the construction accuracy of the connecting member, it interferes with the toilet body, and good construction cannot be performed.

In order to solve such a problem, the clearance may be increased by raising the level of the bottom side of the toilet body. However, since the level of the internal flow path of the toilet body also rises, the level of sealing water from the ball portion to the trap portion also rises. Therefore, it is necessary to raise the level of the rim surface of the toilet body to have a height difference from the water sealing surface.

However, when the level of sealing water rises, the distance between the toilet seat surface and the sealing surface becomes shorter, which causes a new problem of splashing sealing water during use. Further, when flushing water is flown, the sealing surface may rise at a stroke and the ball portion may become almost full, which greatly affects usability.

On the other hand, if the rim surface of the toilet body is raised, the obstacle due to the rise of the level of sealing water will be eliminated. However, since the sitting surface also becomes high, it does not affect healthy people, but it becomes difficult for children and the like to use.

As described above, when the toilet body is reformed and connected to the drain pipe on the building side, in the connection structure of the two divided systems, the drainage pipe between the outlet of the toilet body and the drain pipe on the building side is connected. There are obstacles in construction from the viewpoint of correct flow path connection, and interference with the bottom of the toilet body may become a problem that cannot be ignored during construction.

The problem to be solved in the present invention is to connect the drainage pipe on the building side more easily and to perform good sealing when replacing the toilet body for remodeling, and to use the existing toilet body. It is to provide a connection structure with a drainage pipe that does not require specification changes such as making it higher than the above.

[0015]

According to the present invention, the toilet body is provided with a discharge port facing the floor on which the toilet body is installed.
A connection structure for connecting the discharge port and a drain pipe facing the bottom surface of the toilet body at a position displaced from the discharge port, wherein a discharge side connection pipe connected to the discharge port and drainage connected to the drain pipe It is characterized by comprising a side connecting pipe and a connecting pipe connecting between the discharge side connecting pipe and the drain side connecting pipe.

At least the discharge-side connecting pipe may be provided with a substantially L-shaped internal flow passage, and a corner portion thereof may be formed with a bent vent.

Sealing members may be attached to the outer circumferences of both ends of the connecting pipe to seal and connect between the discharge side connecting pipe and / or the drain side connecting pipe.

Furthermore, the cross-sectional shape of the outer shell of at least both ends of the connecting pipe is flat, and the discharge-side connecting pipe and the drain-side connecting pipe can be inserted or externally inserted into the flat outer portion of the connecting pipe in a fitted state. It can also be configured.

The connecting pipe may be provided with a scale indicating the length to be cut. In this case, the scale can display the cutting length corresponding to the distance from the wall facing the rear side of the toilet body to the core of the drain pipe, or from the center of the outlet of the toilet body to the center of the drain pipe. The cutting length can be displayed according to the distance.

Further, the discharge side connecting pipe is provided with an indication for aligning with the position of the outlet of the toilet body, and the drain side connecting pipe is provided with an indication for indicating the insertion limit position of the connecting pipe. Alternatively, the connecting pipe may be a flexible member capable of expanding and contracting.

Further, at least one of the discharge side connecting pipe and the drain side connecting pipe and the connecting pipe can be mutually inserted or externally inserted, and either the outer circumference of the inner insertion side pipe or the inner circumference of the outer insertion side pipe can be arranged. It is also possible to fix an elastic seal material to one of them and to make it possible to join each of the inner insertion side tube and the outer insertion side tube via the elastic seal material and to adjust the position in the axial direction.

Furthermore, at least one of the discharge-side connecting pipe and the drain-side connecting pipe and the connecting pipe may be sealed and joined together by a male screw and a female screw, respectively, so that the position in the axial direction can be adjusted. .

The drain side connecting pipe may be integrally provided with a fitting ring which can be inserted into the drain pipe side. In this case, the fitting ring has an inner peripheral surface of the drain pipe on its outer peripheral surface. It is also possible to adopt a configuration including a seal ring for sealing.

Further, the discharge side connecting pipe, the connecting pipe, and the drain side connecting pipe may be connected by piping bypassing the central portion in the width direction of the toilet body.

Further, the flow path from the ball portion of the toilet body to the trap flow path is formed so as to be biased to the left or right from the widthwise central portion of the toilet body, and the connecting pipe is trapped from the ball portion. It is also possible to adopt a configuration in which piping is possible while avoiding the outer wall forming the flow path.

[0026]

[Function] Since the flow path from the outlet of the toilet body to the drain pipe on the building side is connected by the two connecting pipes on the drain side and the drain side and one connecting pipe connecting them, it is composed of two members. Compared with the case of doing so, the respective members of the connecting pipe and the connecting pipe are smaller. For this reason, in addition to facilitating the processing at the time of manufacturing each member, the dimensional accuracy is improved and the construction error is reduced.

By providing at least the discharge side connecting pipe with a vent, the internal flow becomes smooth, and the waste is discharged quickly.

By providing the seal members on the outer circumferences of both ends of the connecting pipe, it is possible to perform the construction without using an adhesive.

By making the cross-sectional shape of the outer shell of at least both ends of the connecting pipe flat and fitting the discharge side connecting pipe and the drain side connecting pipe to this, the postures of these connecting pipes can be uniquely determined, The twisting of the axis of each connection is eliminated.

By providing an indication on the connecting pipe indicating the length to be cut at the time of construction, the connecting pipe can be easily cut at the site construction.

In this case, if the cut length corresponding to the distance from the opposing wall to the core of the drainage pipe is displayed on the rear side of the toilet body, the cut length of the connecting pipe is measured only by measuring the distance between the wall and the core. Can be easily known. In addition, if the cut length corresponding to the distance from the center of the outlet of the toilet body to the center of the drainage pipe is indicated on the scale, it is just necessary to measure the distance between these outlets and drainage pipes in the same way. The cutting length of the connecting pipe can be known.

Further, if a display is provided on each of the discharge-side connecting pipe and the drain-side connecting pipe to show the alignment position with the discharge port and the insertion limit of the connecting pipe, the drain-side connecting pipe is temporarily installed on the existing drain pipe. When connecting and installing the discharge side connection pipe, by temporarily aligning the core to the discharge port that changes depending on the position of the toilet body, you can know the insertion length of the connection pipe to the discharge side connection pipe. Accordingly, the connecting pipe can be connected by cutting the connecting pipe.

If the connecting pipe is made flexible, it is possible to carry out construction utilizing its elasticity, and the step of cutting the connecting pipe becomes unnecessary. Further, when at least one of the discharge-side connecting pipe and the drain-side connecting pipe and the connecting pipe are joined to each other through an elastic sealing material by an internal or external insertion relationship, the connecting pipe is connected to at least one of the discharging-side and drain-side connecting pipes. Can be shifted in the axial direction by shaking off the elastic restraint by the elastic sealing material,
This allows the length to be adjusted, eliminating the need to cut the connecting pipe. The same applies to the case where at least one of the discharge-side and drain-side connecting pipes and the connecting pipe are joined by a female screw and a male screw.

If the drain side connecting pipe is integrally provided with a fitting ring that can be inserted into the drain pipe side, it is only necessary to insert the fitting ring together with the sealing material. Simple construction can be performed even more easily.

Further, the discharge side connecting pipe, the connecting pipe, and the drain side connecting pipe can be arranged so as to bypass the central portion in the width direction of the toilet body, thereby forming a trap channel and projecting downward. The connecting pipe does not interfere with the outer wall of the toilet, and it is not necessary to raise the height of the toilet body to secure the clearance.

Further, if the flow path from the ball portion of the toilet body to the trap flow path is shifted from the central part to one of the left and right sides, and the discharge port is located in the substantially central part, the discharge port and the drain pipe will be separated from each other. The straight tubular connecting pipe allows piping without interfering with the bottom wall of the toilet body, and similarly, it is not necessary to set a large clearance.

A substantially inverted U-shaped trap channel 1e is formed downstream of the ball portion 1a, and a discharge port 2 is provided at the lower end of the trap channel 1e facing the floor. The level of the discharge port 2 is slightly higher than that of a normal floor drainage type flush toilet, and an appropriate space is provided between the outer wall of the lower end surface forming the ball portion 1a to the drain port 2 and the floor. There is.

In the vicinity of the lower end of the outer peripheral portion of the toilet body 1, one or a plurality of attachment holes 1f for fixing to the floor are provided. Then, a fixed block 1g made of wood or the like is attached in advance so as to face these attachment holes 1f on the floor surface, and after positioning the toilet body 1, a screw 1h is passed through the attachment hole 1f to the fixed block 1g. By screwing, the toilet body 1 can be installed and fixed on the floor surface. In addition, a heat insulating material 1i made of styrofoam is attached to the bottom surface of the toilet body 1 and the portion around the trap channel 1e. This insulation 1i
As is well known in the art, is incorporated in order to prevent dew condensation on the outer surface of the toilet body 1 in cold weather.

At the upper end of the existing drainage pipe 3 buried in the building side, the floor flange 4 used for connecting the old toilet body before replacement is left as it is. This floor flange 4 is
Those shown in FIGS. 11 and 13 of the publication mentioned in the section of the prior art can be used as they are.

Between the discharge port 2 of the toilet body 1 and the drainage pipe 3, a connection unit 5 which can be installed by changing the length according to the distance between these cores is incorporated. This connection unit 5
Of the discharge side connecting pipe 6, which is connected to the discharge port 2 of the toilet body 1, the drain side connecting pipe 7 which is connected to the drain pipe 3 through the floor flange 4, and the connecting pipe 8 which connects these connecting pipes 6, 7. It is composed of three members, and its plan view is shown in FIG.

The discharge side connecting pipe 6 has a 90 ° elbow shape, and the connecting seat 6a at the upper end is externally inserted around the discharge port 2 and is connected and fixed by a sealing material 2a. Further, a connecting seat 6c having an opening axis in the horizontal direction is provided at the downstream end via a bent 6b that gently bends from the connecting seat 6a. In the illustrated example, the connecting pipe 8 is connected by externally inserting the connecting seat 6c. ing. Then, at the lower end of the discharge side connecting pipe 6, two fixing flanges 6 are provided.
d is provided, and fixing holes can be passed through fixing holes 6e to fix it to the floor.

The drain side connecting pipe 7 is provided with a connecting seat 7a having a horizontal opening axis and a flange 7b having an opening axis orthogonal to this axis. In this example, the connection seat 7a
Is provided with a step portion 7c having an inner diameter larger than that of the downstream portion thereof, the connecting pipe 8 is inserted and the pipe end is received by the step portion 7c. Further, an annular seat 7d fitted to the seal portion of the floor flange 4 is provided on the lower surface of the flange 7b, and screws can be fixed to the floor by passing screws through holes 7e provided at two positions of the flange 7b.

The connecting pipe 8 is a severable pipe material made of a synthetic resin material such as vinyl chloride, and has a joint seat 8a into which the connecting seat 6c of the discharge-side connecting pipe 6 is inserted at one end side. .

When the toilet body 1 is newly installed using the existing drainage pipe 3, it is necessary to know the distance between the outlet 2 of the toilet body 1 and the core of the drainage pipe 3. in this case,
The distance between the wall facing the back side of the toilet body 1 (left side in FIG. 1) and the core of the outlet 2 (generally referred to as “raffin”) can be known from the specifications of the toilet. Therefore, by measuring the distance from the wall to the core of the existing drainage pipe 3, the distance between the cores of the discharge port 2 and the drainage pipe 3 can be known, and the cores of the discharge side connecting pipe 6 and the drainage side connecting pipe 7 can be determined. The length of the connecting pipe 8 is cut so that the distance between them coincides with this.

FIG. 3 shows an example in which the surface of the connecting pipe 8 is graduated in order to simplify the cutting work of the connecting pipe 8. In this example, the connecting pipe 8 is an equal-diameter pipe and the joint seat 8a is not provided. Instead of this, the discharge side connecting pipe 6 is provided.
The connecting seat 6c has a large diameter so that the pipe end of the connecting pipe 8 can abut against the stepped portion 6f therein.

The cut length of the connecting pipe 8 is determined by the toilet body 1
The wall facing the front-back direction (left-right direction in FIG. 1) can be used as a reference, and in the example of FIG. 3, the wall 50 facing the rear end side of the toilet body 1 is used as a reference.

At this time, the distance A from the wall 50 to the core of the drainage pipe 3 can be known by measurement, and the distance B to the core of the outlet 2 when the toilet body 1 is installed can also be known from the specifications of the toilet. You can The distance C from the core of the discharge side connecting pipe 6 to the step portion 6f and the distance D from the core of the drain side connecting pipe 7 to the step portion 7c are also known, and these step portions 6f and 7f are also known.
The distance between c corresponds to the length of the connecting pipe 8. Therefore, the value L, which should be the final length by cutting the connecting pipe 8 under the conditions of the lengths A to D, is L = A- (B + C +).
It can be calculated by D).

Here, when the toilet body 1 is installed, the distance B between the core of the discharge side connecting pipe 6 and the wall 50 corresponds to the previously described raffin. , In the above equation, the only variable is A. Therefore, according to the expected size of A,
As shown in FIG. 2B, a scale M is engraved on the surface of the connecting pipe 8,
The value on the scale M is adjusted to the value corresponding to the distance A. Accordingly, if the length M from the wall 50 to the core of the drainage pipe 3 is simply measured and the scale M corresponding to this numerical value is cut as a cutting surface, the connecting pipe 8 having a cutting length satisfying the above formula can be obtained. can get.

As described above, by providing the scale M on the connecting pipe 8, not only the cutting work of the connecting pipe 8 can be simplified and the construction time can be shortened, but also the connecting pipe 8 is too long or too short. A reliable connection structure is obtained.

After cutting the connecting pipe 8 in the above manner,
The connecting pipe 8 is joined to the connecting pipes 6 and 7 on the discharge side and the drain side, respectively. In the example of FIG. 1, the joint seat 8a of the connecting pipe 8 is fitted over the connecting seat 6c of the discharge side connecting pipe 6 to form the connecting pipe 6c.
The end of the pipe abuts on the stepped portion 8b of the connecting pipe 8, the other end of the connecting pipe 8 is inserted into the connection seat 7a of the drainage side connecting pipe 7, and the pipe end abuts on the stepped portion 7c to be positioned.

FIGS. 4 to 7 show another example. FIG. 4 is a vertical sectional view of the discharge side connecting pipe 6, the drain side connecting pipe 7 and the connecting pipe 8 assembled, and FIG. 5 is a plan view thereof. 6 is a vertical sectional view of the connecting pipe 8. The same members as those in the previous example are designated by common reference numerals, and detailed description thereof will be omitted.

The connecting pipe 8 has a slightly flattened non-circular bilaterally symmetrical cross-sectional shape instead of the circular pipe shape described above, and the connecting pipe 8 into which the discharge side connecting pipe 6 and the drain side connecting pipe are inserted. 7 also has an opening shape that matches this shape.

In the discharge side connecting pipe 6, as in the example of FIG. 3, a step 6f is formed at a portion where the opening cross section on the side where the connecting pipe 8 is inserted is enlarged and the inner diameter is reduced. And the connecting seat 6
The discharge port 2 of the toilet body 1 is dropped into a and a seal member 50 for sealing and joining the same is fitted and integrated. The sealing material 50 has a mortar-shaped portion into which the discharge port 2 is fitted, and a plurality of annular grooves 50a are provided on the inner peripheral wall thereof.

On the surface of the flange 6d of the discharge side connecting pipe 6, a marker line 6d-1 is provided as an indication on a line segment that passes through the core of the connecting seat 6a and is orthogonal to the axis of the connecting pipe 8. The marker line 6d-1 is integrally formed as a protrusion slightly protruding on the surface of the flange 6d.

The drain side connecting pipe 7 is formed by forming a step portion 7c for receiving the tip of the connecting pipe 8 on the inner periphery of the connecting seat 7a into which the connecting pipe 8 is inserted, as in the example of FIG. Then, on the outer peripheral surface of the connection seat 7a, a marker line 7a-1 is provided as a display at a portion corresponding to the position of the step portion 7c. The marker line 7a-1 has a projection shape slightly protruding from the peripheral surface of the connection seat 7a, as in the case of the discharge side connection pipe 6,
It is formed as a line segment orthogonal to the axis of the connection seat 7a.

The connecting pipe 8 is similar to that of the previous example.
A scale M is provided on the peripheral surface. This scale M
Shows the cut length of the connecting pipe 8 corresponding to the distance from the center of the outlet 2 of the toilet body 1 to the center of the drain pipe 3. When connecting the discharge side connecting pipe 6 and the drain side connecting pipe 7 as a non-circular cross section as shown in FIG. 6, these connecting pipes 6, 7 around the core of the connecting pipe 8 are formed.
There is no rotation of, and these positionings are possible. Therefore, the axes of the discharge side connecting pipe 6 and the drain side connecting pipe 7 connected to the discharge port 2 and the drain pipe 3, respectively, can be set parallel to each other, and twisting at the time of connection can be prevented.

Also in this example, the connecting pipe 8 can be cut to a predetermined length for construction by using the scale M as in the previous example. That is, as shown in FIG. 4, X from the wall
When installing so that the core of the drainage port 2 is located at the distance of, the discharge side connecting pipe 6 temporarily puts the marker line 6d-1 at the position of the distance X,
The distance Y from d-1 to the center of the drain pipe 3 is measured. Then, if the connecting pipe 8 is cut using the scale M according to the value of the distance Y, the connection according to the distance between the drainage port 2 and the drainage pipe 3 is possible.

With this construction, the discharge port 2 from the wall
The connecting pipe 8 can be cut even when the distance X up to is arbitrarily changed. For example, there is a water supply pipe to the flush water tank or a water stopcock on the wall side so that the toilet body 1 can be brought close to the wall side. Even if it is not possible to arrange it, it is possible to deal with it and it is possible to perform construction without being restricted by the size of the raffin.

Also, the marker lines 6d-1, 7a-1
By providing the above, it is possible to perform construction at the site without the scale M, which will be described with reference to FIG. 7.

The position of the core P ₁ of the existing drainage pipe 3 can be specified on-site, and the toilet body 1 is installed by draining it so that there is an appropriate distance between the rear end side (left side in FIG. 1) and the wall. The core P _{2 of the} mouth 2 can be set. Then, if the drain side connecting pipe 7 is temporarily fixed to the drain pipe 3, the drain side connecting pipe 7 can be installed so as to match the core P ₁ .
The discharge side connecting pipe 6 to which the connecting pipe 8 is previously connected is temporarily placed with its marker line 6d-1 aligned with the core P ₂ .

The temporary placement of the discharge side connecting pipe 6 is carried out on the floor on the side of the drain side connecting pipe 7 as shown in FIG. After this temporary placement, the marker line 7a-1 which shows the insertion limit position of the connecting pipe 8 corresponding to the position of the step 7c is used as shown in FIG.
Determine the cutting length of and cut the hatched part accordingly.

In this way, without using the scale M on the surface of the connecting pipe 8 and without measuring the distance between the core of the outlet 2 of the toilet body 1 and the core of the drain pipe 3. By using the marker lines 6d-1 and 7a-1, the connecting pipe 8 can be cut to a proper length for construction. Therefore, in FIGS. 5 and 7, the scale M is attached to the connecting pipe 8.
Although an example in which this is drawn is shown, it may not be provided.

Further, the connecting pipe 8 is arranged so that the distance between the drain pipe 3 and the drain port 3 of the toilet body 1 is matched.
Since it is cut, the construction can be performed with the installation position of the toilet body 1 as a reference. Therefore, unlike the construction in which the distance between the wall and the center of the drainage pipe 3 is measured to determine the dimension between the drainage port 2 and the drainage pipe 3, it is possible to perform the installation based on the installation position of the toilet body 1 itself. Becomes For this reason, for example, when a water stopcock or piping is provided along the wall as an existing one, in the construction based on the wall, the rear side of the toilet body 1 interferes with these waterstops or piping. It is easy to fall into this, but there is no such obstacle in construction.

Here, in the example described in FIGS. 1 to 3, when the connecting pipe 8 is a circular pipe, the connecting pipes 6 and 7 on the discharge side and drain side of the connecting pipe 8 are used. At the time of joining, it is possible to apply an adhesive that also serves as a sealing material to the respective joining surfaces and to restrain and join each other.
Joining using an adhesive requires two steps of applying this and inserting and fixing the members. If the adhesive is a quick-drying adhesive, the connecting pipes 6 on the discharge side and the drain side will be used.
There is a possibility that the core of 7 will be fixed in a twisted relationship.

It is possible to carry out seal joining without using an adhesive against such obstacles, and an example thereof is shown in FIG.
Shown in

The illustrated example is a sealing structure between the connecting pipe 8 and the drain side connecting pipe 7, and the outer diameter of the connecting pipe 8 is made smaller than the inner diameter of the drain side connecting pipe 7. In (a), the sealing material 9 is covered as a sealing member on the tube end.
The sealing material 9 has a plurality of elastically deformable fins 9 on its outer circumference and an outer diameter larger than the inner diameter of the drain side connecting pipe 7.
a is arranged at intervals in the axial direction.

When the connecting pipe 8 is inserted into the drain side connecting pipe 7,
The fin 9a falls in the direction opposite to the inserting direction and is elastically deformed, and the tip of the fin 9a is brought into close contact with the inner peripheral surface of the drainage side connecting pipe 7 by the elastic reaction force. As a result, the connection pipe 8 and the drain side connection pipe 7 are sealed by the plurality of fins 9a, and at the same time, they are connected and fixed by the elastic reaction force of the fins 9a.

Further, (b) of FIG.
This is an example in which a book O-ring 10 is provided as a seal member,
Also in this case, by inserting the connecting pipe 8 into the drain side connecting pipe 7, these are sealed and fixed at the same time.

The seal connection by the seal material 9 and the O-ring 10 can be similarly applied between the connecting pipe 8 and the discharge side connecting pipe 6.

Furthermore, when connecting the discharge side and drain side connecting pipes 6, 7 and the connecting pipe 8, the discharge side and drain side connecting pipes 6,
It is necessary to make the opening axes of the connecting seats 6a and the annular seats 7d of 7 parallel to each other. If this comes off,
Twisting occurs between the axes of the discharge-side connecting pipe 6 and the drain-side connecting pipe 7, causing a hindrance to the connection between the drain pipe 3 and the discharge port 2.

In order to eliminate such an obstacle, the cross-sectional shape of both ends of the connecting pipe 8 is made flat as described in the example of FIG. 6, and the cross-sectional shape of the connecting portion of the discharge side and drain side connecting pipes 6, 7 is also this. By making it similar to the connecting pipe 8, it is possible to prevent rotation.

FIG. 9 is a cross-sectional view showing an example of the opening shape of the end portion of the connecting pipe 8 for such a detent.

In FIG. 7A, the bottom surface is linear and the top surface is arcuate, and in FIG. 7B, the shape is close to an ellipse. Then, as described above, the discharge side and drain side connecting pipes 6 and 7 also have a similar relationship to such a cross-sectional shape, so that the discharge side and drain side connecting pipes around the axis of the connecting pipe 8 are formed. The postures of 6 and 7 can be decided uniquely. Therefore, even if the discharge side and drain side connecting pipes 6 and 7 are connected through the connecting pipe 8, the respective postures of these connecting pipes 6 and 7 are surely set to the discharge port 2 and the drain pipe 3. Can be matched.

As described above, by flattening the opening shape of the connecting portion between the connecting pipe 8 and the discharge side and drain side connecting pipes 6 and 7, even if they are connected with an adhesive, an assembly without twisting can be performed. It will be possible. Therefore, it is easy to assemble at the site and can be installed well.

In each of the above examples, the construction method is performed by cutting the connecting pipe 8 to match the positions of the discharge port 2 and the drainage pipe 3. On the other hand, the configuration shown in FIG. 10 can be adopted to eliminate the burden of the cutting work of the connecting pipe 8 and to improve the construction accuracy thereof.

In this example, the discharge side and drain side connecting pipes 6, 7
By connecting the flexible pipes 11 to each other, the length of the connecting pipe 11 itself is adjusted so that the discharge port 2 and the drain pipe 3 can be adjusted.
It is designed to absorb the change in position between and.
As the flexible connecting pipe 11, a bellows pipe having an appropriate strength of a synthetic resin material can be used, and only the both ends thereof are formed into a cylindrical shape, and this portion is formed in each of the discharge side and drain side connecting pipes 6 and 7. Can be connected by plugging in.

By using the flexible connecting pipe 11 as described above, the cutting work of the connecting pipe 11 on the site is completely unnecessary,
The work load is reduced. In addition, the connecting pipe 11 is not cut too short with respect to the distance between the discharge port 2 and the drain pipe 3, and the joint margins of the both ends of the connecting pipe 6 to the discharge side and drain side connecting pipes 6 and 7 are not cut. Therefore, good construction can be performed without causing a seal failure or the like.

On the other hand, for example, as shown in FIGS. 3 and 7, in the case where the length of the connecting pipe 8 is adjusted by cutting the connecting pipe 8, the connecting pipe 8 becomes too short due to the wrong cutting. If it happens, it may affect the construction. Therefore, if the connecting pipe is not flexible and the length can be adjusted without cutting it even when using an ordinary pipe material, the inconvenience at the time of such construction can be eliminated, FIG. 11 shows an example thereof.

In the case of FIG. 11A, a step portion 27c is provided at a portion apart from the pipe end of the drainage side connecting pipe 27, up to this step portion 27c, as in the case shown in FIGS. This is an example in which the connecting pipe 28 can be inserted between the two. And

An O-ring 29 for sealing is attached as an elastic sealing material using the groove 28a.

If the connection pipe 28 is inserted into the drainage side connection pipe 27, the O-ring 29 having such an O-ring 29 will be O.
The seal by the ring 29 and the elastic fitting enable connection and fixing of the connecting pipe 28 and the drain side connecting pipe 27. Further, since the connecting pipe 28 can be inserted at any position up to the step portion 27c, the length can be adjusted by utilizing this, and the cutting work can be performed without any work.

Further, in FIG. 11B, a male screw 30a is provided at the pipe end of the connecting pipe 30, and the connecting pipe 30 is provided between the drain side connecting pipe 31 and the step portion 31a formed therein.
The female screw 31b for joining is formed. In addition,
The step portion 31a is not always necessary, and the drain side connection pipe 31
May be an ordinary pipe material having the same diameter.

With such a screw connection, the connecting pipe 30
Depending on the amount of rotation between the drainage side connection pipe 31 and the drainage side connection pipe 31, the length of the axis line between them can be arbitrarily changed, the length can be adjusted, and similar to the previous example using the O-ring 29. Can be installed. In addition, in actual construction, male screw 3
The sealing tape is wrapped around 0a and screwed into the female screw 31b to achieve sealing.

As described above, by utilizing the O-ring 29 and the screw joint, the discharge port 2 at the time of the remodeling construction
The length between the drainage pipe 3 and the drainage pipe 3 can be adjusted, and the work load can be reduced by cutting the connecting pipe. In addition,
The same is possible not only between the connecting pipe and the drain side connecting pipe but also in the connecting pipe and the discharge side connecting pipe.

Further, in order to simplify the connection between the drain side connecting pipe 7 and the drain pipe 3, the configuration shown in FIGS. 12 and 13 can be adopted. In this example, the one applied to the connection unit 5 shown in FIGS. 1 to 3 is shown.

In the example of FIG. 12, the annular seat 7d of the drain side connecting pipe 7 in the previous example is extended downward to form a fitting ring 7f.

Further, in the example of FIG. 13, a fin-shaped packing 7g is attached as a seal ring around the fitting ring 7f shown in FIG. 12, and this is seated on the inner circumference of the drainage pipe 3 for sealing. is there.

As described above, by providing the fitting ring 7f, the floor flange 4 and the drainage pipe 3 can be inserted and directly connected to each other. Particularly, in the case where the packings 7g and 7h are integrally provided, the sealing work can be simultaneously performed. . Further, the flange 7b of the drainage side connecting pipe 7 can be fixed by screwing it into the floor by passing a screw through the hole 7e without necessarily using the floor flange.

14 to 16 show one embodiment of the invention according to claim 12 of the present application, FIG. 14 is a longitudinal sectional view showing a piping structure, and FIG. 15 is a bottom view.

Between the discharge port 2 and the drainage pipe 3 of the toilet body 1, a connection unit 15 which can be installed by changing the length according to the distance between these cores is incorporated. This connection unit 15
Is a discharge side connecting pipe 16, a drain side connecting pipe 17 connected to the drain pipe 3 via the floor flange 4, and a connecting pipe 18 connecting between the connecting pipes 16 and 17 as in the previous example. As shown in the bottom view of FIG. 15, the connecting pipe 18 constitutes a pipe that bypasses the central portion of the toilet body 1.

As shown in the skeleton diagram of FIG. 16, the discharge side connecting pipe 16 swings the lower end of the flow path coaxial with the discharge port 2 to either the left or right in the width direction of the toilet body 1 and the end thereof. It has a shape extending to the front side (right side in FIG. 14) of the main body 1. Further, the drainage side connecting pipe 18 forms a flow path that extends orthogonally from a portion facing the back side of the toilet body 1 toward the center side of the toilet body 1 and extends downward from the end thereof. The connecting pipe 18 is a straight pipe, and the connection between the discharge-side connecting pipe 16 and the drain-side connecting pipe 17 is positioned so as to be biased to one side in the width direction of the toilet body 1.

Two fixing flanges 16a are provided at the lower end of the discharge side connecting pipe 16, and fixing holes 16b can be fixed to the floor by passing fixing screws through holes 16b. Further, the drain side connecting pipe 17 is also provided with a flange 17a having a hole 17b, and an annular seat 17c fitted to the seal portion of the floor flange 4 is provided on the lower surface of the flange 17a.

Also in this example, the connecting pipe 18 is a pipe material that can be cut, and after being cut to a predetermined length, the connecting pipe 16 and the drain connecting pipe 17 are integrally formed by using an adhesive or the like. The connection unit 15 is formed by connecting them.

Here, the flow path between the discharge port 2 and the drain pipe 3 whose core is located in the center of the toilet body 1 in the width direction is the flow path shape of the discharge side and drain side connecting pipes 16 and 17. Are connected by a connecting pipe 18 passing through a portion of the toilet body 1 which is offset from the center. Therefore, even if the central portion of the toilet main body 1 in the width direction, which is the portion extending from the ball portion 1a toward the trap channel 1e, has a deep deep shape, the connecting pipe 18 does not interfere with the outer contour of this deep portion. Can be plumbed without.

That is, in the toilet body 1 shown in FIG.
Even if the lower end portion is located below the upper end level of the connecting pipe 18, the connecting pipe 18 is a pipe that bypasses the lowest part of the toilet body 1, and thus bypasses the toilet body as in the previous example. 1 does not interfere with the pipe.

In this way, by setting the piping position of the connecting pipe 18 in one of the widthwise directions of the toilet body 1, the clearance between the connecting pipe 18 and the bottom of the toilet body 1 can be set large. Is unnecessary, and the ball portion 1a
It is not necessary to make the depth from to the trap channel 1e shallow. Therefore, the level of sealing water can be maintained at a level similar to that of a normal toilet bowl, and the toilet body 1 does not become high.

FIG. 17 is a view showing an embodiment of the invention according to claim 13 of the present application, and is a longitudinal cross-sectional view of the main part when the toilet body 1 is viewed from the front (from the right side in the example of FIG. 1). is there.

In the toilet body 1 shown in FIG. 1 and the conventional ordinary toilet bowl, the trap channel 1 is provided at the center of the ball portion 1a in the width direction.
The entrance to e is formed, and the trajectory drawn by the core of the trap channel 1e is included in one vertical plane.

On the other hand, in this example, the trap channel 1e from the ball portion 1a is located at a position displaced to the left side in the width direction, and the drainage port 2 is opened at a substantially central position in the width direction. That is, the inlet from the ball portion 1a to the trap passage 1e is located at a position leftward from the center of the toilet body 1 in the width direction, and the trap passage 1e extending from the inlet to the deepest portion is opened. It is arranged on the left side, and the flow path to the discharge port 2 is formed by twisting the flow path on the downstream side of the deepest part to the right side.

The drainage port 2 may be positioned substantially at the center in the width direction of the toilet body 1 as shown in FIG. 17, or may be opened at a position slightly offset to the right. Even if the drainage port 2 is displaced from the core of the toilet body 1 as described above, the connection unit 5 has a length corresponding to the distance between the drainage port 2 and the drainage pipe 3 and is inclined with respect to the center line of the toilet body 1. Can be plumbed as.

With such a flow path configuration from the ball portion 1a to the outlet 2, there is no deep portion in the central portion of the toilet body 1 in the width direction, and a space for accommodating the connection unit 5 is secured. Therefore, it is not necessary to use the bypass connection unit 15 as shown in FIGS. 14 and 15, and for example, the connection unit 5 shown in FIGS. 2 and 3 applied to the example of FIG. 1 can be used as it is. Further, even if the drainage port 2 is provided so as to be biased to the right side in FIG. 17, there is no interference between the connecting pipe 8 and the toilet body 1. Note that, in FIG. 17, the connection unit 5 is shown with reference numerals.

In this example, since the central portion in the width direction of the toilet body 1 projects downwardly, the bulkiness of the toilet body 1 is reduced.
It is not necessary to shake the conduit of the connection unit 15 in the width direction to eliminate the interference as in the example of FIG. For this reason, since there is no interference between the bottom surface portion of the toilet body 1 and the connection unit 5, it is not necessary to raise the toilet body 1, and problems relating to the water sealing level and seating are solved.
