Description

Description: TECHNICAL FIELD The present invention relates to a flush toilet of a floor drainage type, and in particular, when a toilet body is reformed and replaced, a connection between the drainage port and a drainage pipe on a building side can be easily constructed. The present invention relates to a connection structure with a drain pipe made possible.

BACKGROUND ART A floor drain type flush toilet is configured such that a drain port opened on the lower surface of a toilet body is received by a dedicated flange provided at an upper end of a drain pipe on a building side and is connected in a sealed state. This is a general construction structure.

On the other hand, in the case of a renovation in which the toilet is replaced with a new one, the drain pipe on the building side is located at 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 drain port relative to the length of the toilet body in the front-rear direction may be relatively changed. For this reason, when the toilet is installed, there are many cases where the toilet body interferes with the toilet wall and other facilities when the position of the drain pipe on the building side is used as a reference.

In order to eliminate such obstacles during installation, for example, as described in Japanese Utility Model Application Laid-Open No. 2-144085, a connecting member capable of absorbing a displacement between a drain pipe on the building side and a discharge port of the toilet body. There is.

This comprises 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 drainage-side connecting member is placed in a substantially vertical posture. The connection is made in a substantially horizontal direction from the peripheral surface, and the tip is bent downward to connect to the drain pipe. With such a connecting member, the horizontal member of the drain pipe-side connecting member can be cut off from the end of the pipe in accordance with the positional deviation between the outlet and the drain pipe, and the length can be adjusted. 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, connection construction of the flow path is possible.

However, in order to cope with a 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 connection member. For this reason, since the connecting member includes a horizontal portion having one end connected to the outlet-side connecting member and a flange portion connected to the drain pipe, the member itself becomes considerably large. In a horizontal portion having a longer axial line length than a flange portion connected to the drain pipe side, there is a high possibility that the distal end portion is torsionally deformed. When such a twist is generated, the work is performed with the misalignment of the core between the drain pipe side and the discharge port side, and the influence on the seal is great. Furthermore, since the connecting member is L-shaped, it is difficult to handle when cutting, and the workability is poor and the cut surface is liable to bend.

Further, since it is necessary to cut off the horizontal portion of the drainage-side connecting member at the time of construction, it is conceivable that the dimensions may be cut erroneously in the construction at the site. Therefore,
Not only is the work of cutting off troublesome, but also the quality of construction depends on how the cutting work is performed, and the problem of workability remains.

Furthermore, since the connection of the connecting member to the discharge port and the drainage pipe is a method of fixing and sealing with an adhesive, the bonding work is also troublesome, and if the application of the adhesive is not sufficient, the sealing will be defective. There is a high possibility of a water leak accident.

On the other hand, the bottom side of the toilet body has a trap-shaped flow path extending from the ball portion and has a substantially U-shaped shape protruding downward, and the space for piping is limited. For this reason, the clearance between the connection member and the bottom wall of the toilet body cannot be made large, and depending on the installation accuracy of the connection member, the connection member may interfere with the toilet body, and good construction cannot be performed.

In order to solve such a problem, the clearance may be increased by increasing the level on the bottom side of the toilet body. However, since the level of the internal flow path of the toilet body also increases, the level of water sealing from the ball portion to the trap portion also increases. For this reason, it is necessary to raise the level of the rim surface of the toilet body so as to have a height difference from the water sealing surface.

However, when the level of water sealing rises, the distance between the toilet seat surface and the water sealing surface becomes shorter, and a new problem of splashing of the water sealing at the time of use occurs. Also, when flushing water, the sealing surface may rise at a stretch and it may be almost full in the ball part,
It greatly affects usability.

On the other hand, if the rim surface of the toilet main body is raised, the obstacle due to the increase in the level of water sealing is eliminated. However, since the seating surface also becomes higher, there is no effect on healthy people,
It becomes difficult for children and others to use.

As described above, when the toilet body is reformed and connected to the drainage pipe on the building side, in the connection structure of the two-part system, the correct flow path between the discharge port of the toilet body and the drainage pipe on the building side is used. There is an obstacle in the construction from the viewpoint of the connection of the above, and the interference with the bottom of the toilet body may be a problem that cannot be ignored in the construction.

If the drainpipe is arranged perpendicular to the vertical wall surface, it is necessary to connect the outlet of the toilet according to the height position of the drainpipe. Similarly, there is a problem that the position adjustment is difficult.

The present invention has been made in consideration of the above-described points, and an object thereof is to further simplify connection with a drain pipe on a building side when, for example, exchanging a toilet body for reforming. In addition, an object of the present invention is to provide a connection device with a drain pipe which can be satisfactorily sealed. Another object of the present invention is to provide a drainage connection device that does not require a change in specifications such as making the toilet body higher than an existing one at the time of connection.

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 is a longitudinal sectional view of a flush toilet provided with a connecting device according to the present invention.

The toilet body 1 includes a ball portion 1a, a water supply chamber 1b for supplying cleaning water to the ball portion 1a, a rim water passage 1c, and a jet channel 1d for siphon. A substantially inverted U-shaped trap flow path 1e is formed downstream of the ball portion 1a, and a discharge port 2 is provided at a lower end thereof facing the floor surface. The level of the outlet 2 is slightly higher than that of a normal flush toilet, so that an appropriate space is formed between the floor and the floor at the lower end surface from the ball portion 1a to the outlet 2. It has become so.

In the vicinity of the lower end of the outer peripheral portion of the toilet body 1, one or more appropriate mounting holes 1f for fixing to the floor surface are provided. A fixing block 1g made of wood or the like is previously mounted on the floor so as to face these mounting holes 1f, and after positioning the toilet main body 1, screws 1h are mounted on the mounting holes 1f.
And screwed into the fixing block 1g, the toilet body 1 can be installed and fixed on the floor surface. A heat insulating material 1i made of styrene foam is provided on the bottom surface of the toilet body 1 and on the trap channel 1e and its surroundings.
Paste. As is well known in the art, this heat insulating material 1i is incorporated to prevent dew condensation on the outer surface of the toilet body 1 in cold weather.

At the upper end of the existing drain pipe 3 buried on the building side, the floor flange 4 for connecting the old toilet body before replacement is left as it is. This floor flange 4 is shown in FIGS. 11 and 13 of Japanese Utility Model Laid-Open No. 2-144085 described as the prior art.
The one shown in the figure can be used as it is.

Between the discharge port 2 and the drain pipe 3 of the toilet body 1, a connection unit 5 that can be constructed by changing the length in accordance with the distance of these cores is incorporated. This connection unit 5 is a toilet body 1
From a discharge side connection pipe 6 connected to the discharge port 2, a drain side connection pipe 7 connected to the drain pipe 3 through the floor flange 4, and a connection pipe 8 connecting between these connection pipes 6,7. FIG. 2 is a plan view showing the configuration.

The discharge side connection pipe 6 is in the shape of a 90 ° elbow. The connection seat 6a at the upper end is externally inserted around the discharge port 2 and is connected and fixed by the sealing material 2a. In addition, a continuous seat 6c having an opening axis in the horizontal direction is provided at the downstream end via a vent 6b that bends gently from the connection seat 6a, and in the illustrated example, the connection pipe 8 is connected by extrapolating the connection seat 6c. ing. A fixing flange 6d is provided at the lower end of the discharge side connection pipe 6, and a fixing screw can be fixed to the floor through a hole 6e formed in the fixing flange 6d.

The drain side connection pipe 7 is a connection seat having a horizontal opening axis.
7a and a flange 7b having an opening axis orthogonal to the axis. In this example, the connection seat 7a is provided with a step 7c having an inner diameter larger than that of the downstream portion, and the connecting pipe 8 is inserted thereinto and the pipe end is received by the step 7c. An annular seat 7d is provided on the lower surface of the flange 7b so as to fit into the sealing portion of the floor flange 4, and can be fixed to the floor through screws through holes 7e provided at two places of the flange 7b.

The connection pipe 8 is a cutable pipe material made of a synthetic resin material using, for example, vinyl chloride or the like, and has a connection seat 8a formed at one end thereof, into which the connection seat 6c of the discharge-side connection pipe 6 is inserted.

When newly installing the toilet body 1 using the existing drain pipe 3, it is necessary to know the distance between the outlet 2 of the toilet body 1 and the core of the drain pipe 3. In this case, the toilet body 1
Between the wall facing the back side (left side in FIG. 1) and the core of the outlet 2 (generally referred to as "raffin")
Can be known from the toilet specifications. Therefore, by measuring the distance between the wall and the core of the existing drain pipe 3, the distance between the outlet 2 and the core of the drain pipe 3 can be determined, and the core of the discharge-side connection pipe 6 and the core of the drain-side connection pipe 7 can be determined. The length of the connecting tube 8 is cut so that the distance between them becomes equal to this.

FIG. 3 shows an example in which a scale is provided on the surface of the connecting pipe 8 in order to simplify such a cutting operation of the connecting pipe 8. In this example, the connecting pipe 8 is an equal-diameter pipe and does not have the connecting seat 8a. Instead, the connecting seat 6c of the discharge-side connecting pipe 6 is used.
Has a large diameter so that the pipe end of the connecting pipe 8 can be abutted against a step 6f inside thereof.

The cutting length of the connecting pipe 8 can be determined with reference to the wall facing the front and rear direction (left and right direction in FIG. 1) of the toilet main body 1, and in the example of FIG. The wall 50 to be used as a reference.

At this time, the distance A from the wall 50 to the core of the drain pipe 3 can be known by measurement, and the distance B from the core of the outlet 2 when the toilet body 1 is installed can also be known from the specifications of the toilet. The distance C from the core of the discharge-side connection pipe 6 to the step 6f and the distance D from the core of the drain-side connection pipe 7 to the step 7c.
Is also known, and the distance between these steps 6f, 7c corresponds to the length of the connecting pipe 8. Therefore, the value L to be cut and the final length of the connecting pipe 8 can be calculated by L = A- (B + C + D) for the above conditions of the lengths A to D.

Here, in the installation of the toilet body 1, the distance B between the core of the discharge-side connecting pipe 6 and the wall 50 is equivalent to the above-described raffin. The only variable in the formula is A. Therefore, as shown in FIG. 4, a scale M is cut on the surface of the connecting pipe 8 in accordance with the predicted size of A, and the value of the scale M is adjusted to a value corresponding to the distance A. Thus, by simply measuring the length from the wall 50 to the core of the drain pipe 3 and cutting the scale M corresponding to this value as a cut surface, the connecting pipe 8 having a cut length satisfying the above equation can be obtained. can get.

By providing the scale M on the connecting pipe 8 in this way, the cutting operation of the connecting pipe 8 is simplified, and not only the construction time can be reduced, but also the connecting pipe 8 is not too long or too short. A connection structure can be reliably 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 connecting seat 8a of the connecting pipe 8 extrapolates the connecting seat 6c of the discharge-side connecting pipe 6, and the pipe end of the connecting pipe 6c abuts against the step 8b of the connecting pipe 8. Is inserted into the connection seat 7a of the drain-side connection pipe 7, and the pipe end is positioned by abutting on the step 7c.

FIGS. 5 to 11 show another embodiment of the present invention. The same members as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In this embodiment, the connecting pipe 8 has a slightly flat non-circular symmetrical cross-sectional shape instead of the above-mentioned circular pipe, and the discharge-side connecting pipe 6 into which the connecting pipe 8 is inserted and the drainage pipe. The side connection pipe 7 also has an opening shape corresponding to this shape.

As in the example of FIG. 3, the discharge-side connecting pipe 6 has a stepped portion 6f 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. Then, a sealing member 50 for dropping the discharge port 2 of the toilet body 1 and sealingly joining the discharge port 2 into the connection seat 6a is integrated. The sealing material 50 has a portion in which the discharge port 2 is fitted in a mortar shape, and a plurality of annular grooves 50a are provided in an inner peripheral wall thereof.

On the surface of the flange 6d of the discharge side connection pipe 6, a marker line 6d-1 is provided as a display on a line passing through the center of the connection seat 6a and orthogonal to the axis of the connection pipe 8. This marker line
6d-1 is integrally formed as a projection slightly projecting from the surface of the flange 6d.

The drainage-side connection pipe 7 has a stepped portion 7c that receives the tip of the connection pipe 8 formed on the inner periphery of a connection seat 7a into which the connection 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 7c. This marker line 7a-
Reference numeral 1 is a projection slightly protruding from the peripheral surface of the connection seat 7a as in the case of the discharge-side connection pipe 6, and is formed as a line segment orthogonal to the axis of the connection seat 7a.

The connecting pipe 8 is provided with a scale M on its peripheral surface, similarly to the above-described embodiment. The scale M indicates the cutting 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 these to the discharge side connection pipe 6 and the drain side connection pipe 7 as a non-circular cross section as shown in FIG. 7, these connection pipes 6, 7 around the core of the connection pipe 8 are connected.
These rotations can be performed without rotation. Therefore, the discharge side connection pipe 6 and the drainage side connection pipe 7 can set the axes of the portions connected to the discharge port 2 and the drainage pipe 3 to be parallel to each other, and can prevent twisting at the time of connection.

Also in this example, the connection pipe 8 can be cut to a predetermined length using the scale M in the same manner as in the above embodiment. That is, as shown in FIG.
When the discharge port 2 is installed so that the core of the discharge port 2 is positioned at the distance of the discharge line 2, the discharge side connecting pipe 6 temporarily places the marker line 6d-1 at the position of the distance X, and places the marker line 6d-
The distance Y from 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 outlet 2 and the drain pipe 3 is possible.

With such a construction, even when the distance X from the wall to the discharge port 2 is arbitrarily changed, the connection pipe 8 can be cut, for example, a water supply pipe to the washing water tank or a water stoppage on the wall side. Even if the toilet main body 1 cannot be arranged close to the wall side due to a stopper or the like, it is possible to cope with the situation, and it is possible to perform construction without being limited by the dimensions of the raffin.

In addition, by providing the marker lines 6d- and 7a-1,
Even if the scale M is not provided, it is possible to perform the work on site, and this will be described with reference to FIGS.

The position of the core P ₁ of the existing drain pipe 3 can be specified on site, and the installation of the toilet body 1 is at the rear end side (left side in FIG. 1).
Between the walls so as to become appropriate distance, it can be set core P ₂ outlets 2. And the drain side connection pipe 7
Is temporarily fixed to the drain pipe 3, the drain side connection pipe 7 is connected to the core P ₁
The discharge-side connecting pipe 6 to which the connecting pipe 8 is connected in advance is connected to the marker line 6d-
1 is temporarily placed in accordance with the core P _2.

The temporary placement of the discharge side connection pipe 6 is performed on the floor surface beside the drain side connection pipe 7, as shown in FIG. And
After this temporary placement, as shown in FIG. 9, the cutting length of the connecting pipe 8 is determined using the marker line 7a-1 indicating the insertion limit position of the connecting pipe 8 corresponding to the position of the step 7c. Then, the hatched portion is cut according to this.

Thus, the marker line 6d can be used 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. -1,7a
By using -1, it is possible to cut the connecting pipe 8 to an appropriate length and perform the work. Therefore, FIG.
8 and 10, an example in which the scale M is drawn on the connecting pipe 8 is shown, but the scale may not be provided.

Moreover, since the connecting pipe 8 is cut so that the distance from the drain pipe 3 is adjusted based on the position of the outlet 2 of the toilet main body 1, construction based on the installation position of the toilet main body 1 becomes possible. . Therefore, unlike the construction in which the distance from the wall to the center of the drain pipe 3 is measured to determine the dimension between the outlet 2 and the drain pipe 3, installation based on the installation position of the toilet body 1 itself is performed. It becomes possible. For this reason, for example, in the case where a water stopcock or a pipe is provided as an existing one along the wall, in the construction based on the wall, the rear side of the toilet body 1 and the water stopcock or the pipe interfere with each other. However, there is no such obstacle in construction.

Here, in the example described with reference to FIG. 1 to FIG. 3, when the connecting pipe 8 has a circular pipe shape, the connecting pipe 8 is connected to the connecting pipes 6 and 7 on the discharge side and the drain side. At the time of joining, an adhesive that also serves as a sealing material can be applied to each joint surface to restrict and connect each other. Joining using an adhesive requires two steps of painting and inserting and fixing the members together. If the adhesive is quick-drying, the connecting pipes 6 and 7 on the discharge side and drain side are required. The core may be fixed in a twisted relationship.

For such obstacles, it is possible to perform seal joining without using an adhesive, and an example is shown in FIGS.
Shown in the figure.

The illustrated example is a seal 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, and in FIG. A sealing material 9 is put on the pipe end as a sealing member. This sealing material 9
Has a plurality of fins 9a which can be elastically deformed and whose outer diameter is larger than the inner diameter of the drainage-side connection pipe 7 arranged at intervals on the outer periphery thereof in the axial direction.

When the connection pipe 8 is inserted into the drain-side connection pipe 7, the fin 9a falls down in the opposite direction to the insertion direction and is elastically deformed, and the tip end of the fin 9a comes into close contact with the inner peripheral surface of the drain-side connection pipe 7 due to the elastic reaction force. . As a result, the space between the connection pipe 8 and the drain-side connection pipe 7 is 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.

FIG. 13 shows an example in which two O-rings 10 are provided on the outer periphery of the connecting pipe 8 as sealing members.
These are sealed and fixed by inserting them into the drainage connection pipe 7.

Note that such a seal connection by the seal member 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 connection pipe 8 with the discharge-side and drain-side connection pipes 6, 7 and the connection axis 6a and the opening axis of the annular seat 7d of the discharge-side and drain-side connection pipes 6, 7, respectively, the opening axes are parallel to each other. There is a need to. If it is removed, a twist occurs between the axis of the discharge side connection pipe 6 and the axis of the drainage connection pipe 7, which hinders the connection between the drainage pipe 3 and the discharge port 2.

In order to eliminate such an obstacle, as described in the example of FIG. 7, the cross-sectional shape of both ends of the connecting pipe 8 is made flat, and the cross-sectional shape of the connecting part of the discharge-side and drain-side connecting pipes 6 and 7 is also changed to this connection. In the same manner as the pipe 8, the rotation can be stopped.

14 and 15 are cross-sectional views showing examples of the shape of the opening at the end of the connecting pipe 8 for preventing such rotation.

FIG. 14 shows a case where the bottom surface is linear and the top surface is arc-shaped, and FIG. 15 has a shape close to an ellipse. As described above, the discharge-side and drain-side connection pipes 6 and 7 also have a similar relationship to such a cross-sectional shape, so that the discharge-side and drain-side connection pipes around the axis of the connection pipe 8 are formed. 6, 7 postures can be uniquely determined. Therefore, even if the discharge-side and drain-side connection pipes 6 and 7 are connected via the connection pipe 8, the respective postures of these connection pipes 6 and 7 can be reliably applied to the outlet 2 and the drain pipe 3. Can be matched.

Thus, the connecting pipe 8 and the discharge-side and drain-side connection pipes 6, 7
By making the shape of the opening of the connecting portion flat, it is possible to assemble without twisting, even when connecting with an adhesive. Therefore, assembling on site can be simplified, and the construction can be performed well.

In each of the above examples, by cutting the connecting pipe 8,
The construction method according to the position of the discharge port 2 and the drain pipe 3 is performed. On the other hand, the configuration shown in FIG. 16 can be adopted to eliminate the burden of the cutting operation of the connecting pipe 8 and to improve the construction accuracy.

In this example, the connection between the discharge side and the drainage side connection pipes 6 and 7 is made by connecting the flexible connection pipe 11 to adjust the length of the connection pipe 11 itself. This is to absorb the change in the position between them. Flexible connecting pipe
11 can use a bellows tube having an appropriate strength of a synthetic resin material, can be connected by inserting only this portion into the discharge side and the drain side connection pipes 6 and 7 with only both ends thereof being cylindrical. .

When the flexible connecting pipe 11 is used in this way, the work of cutting the connecting pipe 11 on site is not required at all, and the work load is reduced. Further, the connecting pipe 11 is not cut so as to be too short with respect to the distance between the discharge port 2 and the drain pipe 3, and a joint allowance at both ends of the connecting pipe 11 for the discharge side and the drain side connection pipe 6, 7 is provided. Therefore, good construction can be performed without inducing sealing failure and the like.

On the other hand, for example, when the length is adjusted by cutting the connecting pipe 8 as shown in FIGS. 4, 8 and 10, the connecting pipe 8 is cut too short by mistake. In such a case, there is a possibility that the construction will be affected.

Therefore, if the connecting pipe is not flexible and the length can be adjusted without cutting the pipe even when using a normal pipe material, such inconvenience at the time of construction can be solved, 17 and 18 show examples.

17 is the same as that shown in FIGS. 1 to 3 except that a stepped portion 27c
This is an example in which the connecting pipe 28 can be inserted up to the step 27c. A groove 28a is formed in the outer peripheral surface near the pipe end of the connecting pipe 28, and an O-ring 29 for sealing is attached as an elastic sealing material using the groove 28a.

If such an O-ring 29 is provided, a connecting pipe
28 is inserted into the drain side connection pipe 27, the connection pipe 28 and the drain side connection pipe 27 are sealed by the O-ring 29 and elastically fitted.
Can be fixed. And the connecting pipe 28 is a step 27
Since it can be inserted at any position up to the c part,
Using this, the length can be adjusted, and the cutting work can be performed without any need.

In addition, FIG. 18 shows that a male screw 30a is provided at the pipe end of the connecting pipe 30 and a female screw 31b which joins the connecting pipe 30 to the drain side connecting pipe 31 up to a step 31a formed therein. Is formed. Note that the step portion 31a is not necessarily required, and the drain-side connection pipe 31 may be a normal pipe material having the same diameter.

With such a screw connection, the axial length between the connecting pipe 30 and the drain-side connecting pipe 31 can be arbitrarily changed depending on the amount of rotation between the connecting pipe 30 and the drain-side connecting pipe 31, and the length can be adjusted. The same construction as the above embodiment using the O-ring 29 is possible. In actual construction, sealing is performed by wrapping a seal tape around the male screw 30a and screwing it into the female screw 31b.

As described above, by using the O-ring 29 and the screw connection, it is possible to adjust the length between the outlet 2 and the drain pipe 3 at the time of the renovation work, and the cutting work of the connecting pipe can be omitted. Only the construction burden is reduced. In addition, not only between the connecting pipe and the drain-side connecting pipe, but also in the connecting pipe and the discharging-side connecting pipe.

Further, in order to simplify the connection between the drain side connection pipe 7 and the drain pipe 3, the configuration shown in FIGS. 19 and 20 can be adopted. In this example, an example applied to the connection unit 5 shown in FIGS. 1 to 3 is shown.

In the example of FIG. 19, the annular seat 7d of the drain-side connection pipe 7 in the above embodiment is extended downward to form a fitting ring 7f.
7f is inserted into the existing drainage pipe 3, and packing 7h is filled around as a seal ring.

In the example of FIG. 20, a fin-shaped packing 7g is attached as a seal ring around the fitting ring 7f shown in FIG. 19, and this is seated on the inner periphery of the drain pipe 3 to seal. .

In this way, by providing the fitting ring 7f, the floor flange 4 and the drain pipe 3 can be inserted and directly connected to each other. Particularly, in the case where the packings 7g and 7h are integrally provided, sealing can be performed simultaneously. Further, the flange 7b of the drain side connection pipe 7 can be fixed by screwing the hole 7e into the floor through a screw without necessarily using the floor flange, and this also simplifies the construction.

FIGS. 21 to 23 show another embodiment of the present invention.

In this embodiment, a connection unit 15 is installed between the discharge port 2 of the toilet body 1 and the drain pipe 3 so that the length of the connection unit 15 can be changed according to the distance between the cores. The connection unit 15 includes a discharge side connection pipe 16, a drain side connection pipe 17 connected to the drain pipe 3 via the floor flange 4, and a connection connecting these connection pipes 16, 17, as in the above-described embodiment.

That is, the inlet from the ball portion 1a to the trap channel 1e is positioned so as to be deviated to the left from the center in the width direction of the toilet body 1, and the trap channel 1e extending from the inlet to the deepest portion is set. 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 right side downstream from the deepest part.

The outlet 2 may be located substantially at the center of the toilet body 1 in the width direction as shown in FIG. 24, or may be opened at a position slightly biased to the right. Thus, outlet 2
Even if is displaced from the core of the toilet body 1, the connection unit 5 can have a length corresponding to the distance between the discharge port 2 and the drain pipe 3, and can be piped in an oblique posture with respect to the center line of the toilet body 1. .

With such a flow path configuration from the ball portion 1a to the discharge port 2, there is no deep portion at the center in the width direction of the toilet body 1, and a space for accommodating the connection unit 5 is secured.
Therefore, it is not necessary to use the detouring connection unit 15 shown in FIGS. 21 and 22, 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. can do. In addition, outlet 2
Even in the case where it is biased to the right in the figure, there is no interference between the connecting pipe 8 and the toilet body 1.

In this example, since the central portion in the width direction of the toilet body 1 protrudes downward, the bulk of the connection unit 15 is swung in the width direction as in the example of FIGS. 21 and 22 to eliminate interference. No need. Therefore, there is no interference between the bottom portion of the toilet main body 1 and the connection unit 5, so that the height of the toilet main body 1 does not need to be increased, and problems relating to the water sealing level and seating can be solved.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, two connection pipes on the discharge side and the drainage side and one connection pipe are used for flow path connection. The members can be made smaller, their manufacture can be simplified, and the dimensional accuracy can be kept high, so that the construction accuracy can be improved. In particular, by using three members, the connecting pipe can be made a straight pipe, and the cutting work for adjusting the length becomes easy.

Further, the connecting pipes on the discharge side and the drain side can be miniaturized, so that the construction can be performed with less bulk than the conventional structure.

In addition, the work of cutting the connecting pipe at the site construction is further facilitated, and the scale can be scaled simply by measuring the distance between the wall and the core of the existing drain pipe or the distance between the outlet of the toilet bowl and the drain pipe. The connecting pipe can be cut to the correct length by using it, so that the workability can be improved and a reliable connection can be made.

In addition, since the drain-side and drain-side connection pipes can be temporarily placed at the installation position and the length of the connection pipe can be determined and cut, the installation based on the installation position of the toilet itself can be used instead of the wall-based installation. For example, even when there is an existing pipe on the wall, the work can be performed without interfering with the existing pipe. Also, it is not necessary to measure the distance of the drain pipe from the wall in the construction, and the labor is reduced.

Furthermore, in the present invention, since the bottom of the toilet body and the adjustable length piping for connecting the discharge port of the toilet body and the drainage pipe on the building side do not interfere with each other, the height of the toilet body is increased. There is no need to provide clearance with piping. For this reason, the sealing surface does not rise and the toilet seat does not rise,
The harmful effect of the splashing of the sealing water and the difficulty in sitting down is prevented.

Further, according to the present invention, it is possible to cope with a drainage structure for draining to the wall side, and it is possible to easily configure drainage channels corresponding to various drainage height positions using the same toilet body.
