Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a piping unit with a toilet bowl.

(Prior Art) Recently, a structure called a piping unit is widely used in toilets and the like.

This structure has a structure in which a frame body is assembled with a lightweight steel aggregate, appropriate pipes are inserted into the frame body, and the upper surface and the front surface of the frame body are covered with a counter member and a panel member, respectively. There is.

In the present invention, the piping unit with a toilet bowl refers to a structure in which a toilet bowl is additionally attached to the structure called the above-mentioned piping unit.

The piping unit with a toilet bowl requires drainage piping that fits into the toilet bowl.

This pipe is generally composed of a main pipe having a relatively large diameter arranged on the rear side of the panel member and a branch pipe having a relatively small diameter that guides drainage from the toilet to the main pipe.

The toilet bowl is disposed on the front side of the panel member, and the branch pipe penetrates the panel from the front side to the rear side to engage with the main pipe.

In the conventional piping unit with a toilet bowl, the branch pipe and the main pipe are connected by a T-shaped joint.

The T-shaped joint is composed of a relatively large-diameter straight pipe portion provided on the main pipe and a relatively small-diameter side branch projecting at a right angle to the straight pipe portion. The downstream end of is connected.

(Problems to be Solved by the Invention) Waste water is discharged from the toilet bowl to the branch pipe.

This drainage flows into the straight pipe portion from the side branch of the T-shaped joint, further flows in the axial direction of the straight pipe portion, and flows down in the main pipe.

When the flow rate of the drainage is relatively large, the drainage flowing from the side branch into the straight pipe portion flows in the straight pipe portion in the axial direction without significantly damaging the water force.

However, if the flow rate of the wastewater is relatively small, the water force exhibited by the wastewater when flowing axially in the straight pipe section depends on the momentum that the wastewater had when it entered the straight pipe section. The momentum is proportional to the magnitude of the component possessed in the axial direction of the straight pipe portion.

When flowing into the straight pipe portion, the drainage mainly flows in the axial direction of the side branch, and the axial direction of the side branch coincides with the radial direction of the straight pipe portion.

Therefore, the drainage has almost no momentum component in the axial direction of the straight pipe portion when flowing into the straight pipe portion, and when the water flow in the straight pipe portion tends to flow in the axial direction, the water force is greatly attenuated. Become.

On the other hand, the wastewater discharged from the toilet bowl contains a considerable amount of toilet paper, solid obscene materials, etc. that are difficult to flow.

Such a non-fluid substance accumulates in the place where the water pressure of the drainage is weakened, that is, in the straight pipe portion of the joint, and causes the clogging of the pipeline.

In order to prevent such a situation, in the conventional piping unit with a toilet bowl, the flow rate of the wastewater discharged from the toilet bowl had to be set relatively large.

For this reason, a relatively large amount of water was required to wash the toilet bowl.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a frame body assembled from lightweight steel aggregate, a counter member that covers the upper surface of the frame body, and a panel member that covers the front surface of the frame body. A large-diameter drain main disposed in the frame on the rear side of the panel member, and an opening of the panel member penetrating from the front to the rear of the panel main member and obliquely abuttingly joined to the drain main to plan view of the toilet bowl. It consists of a small-diameter drain branch pipe that allows the drainage to flow down to the drain main, and this drain branch pipe branches from this drain main pipe, tilts upward, extends forward, and then curves horizontally, and this curved pipe. It is composed of a joint member that connects to the drainage port of the toilet bowl, and the front end portion of this joint member is provided with a funnel-shaped flange portion forward, and between the outer peripheral surface of this flange portion and the front surface of the panel member. A flange stopper was installed on the.

(Operation) The drainage discharged from the toilet bowl into the drain branch pipe obliquely flows into the drain main from the downstream end of the drain branch pipe, and flows down in the drain main in the axial direction according to the inclination.

The momentum possessed by the drainage when flowing into the drainage main always includes a component directed inward in the radial direction of the drainage main, as well as a component further directed in the axial direction of the drainage main.

This axial momentum component imparts a water force of a magnitude corresponding to the drainage that is about to start flowing down in the drainage main.

Therefore, even if the flow rate is relatively small, the waste water can entrain the non-fluid substances contained therein along the waste water main.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

The curved pipe 12 is composed of a straight pipe portion 12a coaxially inserted and joined to the opening peripheral edge portion 10c of the drainage main pipe 10, and a tip portion 12b facing the rear surface 4a of the panel member 4 from the rear side.

The joint member 13 includes a short tube portion 13a which is coaxially loosely fitted to the tip portion 12b of the curved tube 12 from the front, an enlarged diameter portion 13b provided at the front end of the short pipe portion 13a, and an outer periphery of the enlarged diameter portion 13b. And a flange portion 13c formed in a funnel shape toward the front.

An elastic packing material 14 is filled between the short pipe portion 13a and the curved pipe tip portion 12b, a reinforcing ring 15 is welded to the front surface of the expanded diameter portion 13b, and the flange portion 13c is biased with respect to the short pipe portion 13a. I have a heart.

The flange portion 13c is loosely fitted in a circular opening 4b formed in the panel member 4, and a flange stopper 16 is interposed between the outer peripheral surface of the flange portion 13c and the front surface of the panel member 4.

A tubular protrusion 5b is formed on the rear portion 5a of the toilet bowl 5, the inside of the protrusion 5b serves as a drain port 5c, and the flange 13c of the joint member 13 is provided on the outer periphery of the protrusion 5b. The inner peripheral surfaces are held together via a sealing material 17.

The downstream end 12c of the straight pipe portion 12a of the curved pipe 12 is a drainage main pipe.
It is obliquely fitted into the opening peripheral edge portion 10c of 10 and is fixed by adhesion. The tip 12d of the downstream end 12c is flush with the inner wall 10d of the drain main 10.

The drain main 10 is oriented such that its axis 18 is parallel to the panel member 4. The axis 18 of the drain main 10 intersects with the axis 19 of the straight pipe portion 12a at a point 20.
The main pipe axis portion 18a located on the upstream side as viewed from the front makes an acute angle α with the straight pipe portion axis center 19.

The operation of the piping unit with a toilet having the above-described configuration will be described below.

The pipe unit 1 with a toilet bowl is carried into the construction site as an appropriately assembled product after the factory production. At this time, the curved pipe 12 is already joined to the drainage main 10.

At the site, as shown in FIG. 1, first, the frame body 2 is fixed to the floor 9 by the anchor bolts 8. With respect to both the fixed frame body 2 and the planned installation position of the toilet 5, the drain main 10 and other The piping is centered, and then the counter member 3 is attached to the frame body 2.
And the panel member 4 is attached.

After that, a joint construction is performed in relation to the joint member 13 of the drain branch pipe 11, and in addition, an installation work of the toilet bowl 5 is performed.

When fitting the joint member 13, as shown in FIGS. 2 and 3, first, the stopper 16 is fitted into the flange portion 13c of the member 13, and then the short pipe portion 13a is inserted into the circular opening 4a of the panel member 4 from the front. Insert it and open the shaft center of flange 13c 4
Bring to the center of b. Then, the member 13 is rotated around the axis of the flange portion 13c, and the drainage main pipe 10 is slightly rotated around the axis 18 thereof, so that the downstream end of the short pipe portion 13a and the tip end portion 12b of the curved pipe 12 are connected. Positioned coaxially, the elastic packing material 14 is applied between the both 13a, 12b, and the member 13 is pushed again to the downstream side.

Then, the flange stopper 16 comes into contact with the front surface of the panel member 4, whereby the axial position of the joint member 13 is determined.

Therefore, a sealing material 17 is applied around the protruding portion 5b of the toilet bowl rear portion 5a, and the protruding portion 5b with the sealing material applied is used as a joint member.
While applying the flange portion 13c of 13 substantially concentrically,
Is fixed in place on the floor 9.

Then, the flange portion 13c is centered with respect to the drainage port 5c of the toilet bowl 5 and, at the same time, a stopper for the panel member 4.
16 positions are also fixed.

Finally, the rear part 5a of the toilet bowl is bolted to the frame body 2.

After the installation of the piping unit with a toilet bowl 1 is completed, water is supplied from the water supply pipe 7 to the toilet bowl 5 by operating the flush valve 7a with an external switch (not shown).

This water cleans the inside of the toilet bowl 5 and is discharged vigorously into the joint member 13 from the drain port 5c of the rear portion 5a of the toilet bowl as waste water accompanied by non-fluid substances in the toilet bowl 5.

This drainage flows from the short pipe portion 13a of the joint member 13 to the tip portion 1 of the curved pipe 12.
2b, flows down from the tip portion 12b of the curved pipe 12 along the straight pipe portion 12a, and entrains the non-fluid substance into the drainage main pipe 10 from the downstream short portion 12c of the straight pipe portion 12a. Inflow while doing.

The drainage that has flowed into the drainage main 10 further flows down in the drainage main 10 in the downstream side thereof, that is, in the direction of arrow B in FIG.

If the flow rate of the waste water is relatively large, the waste water retains a water force enough to easily accompany the non-fluid substance even when the waste water flows into the waste water main pipe 10 and then further flows down.

When the flow rate of the wastewater is relatively small, the water force exhibited by the wastewater at the time of starting the flow of the wastewater in the main drainage pipe 10 depends on the momentum possessed when the drainage main pipe 10 was introduced.

When flowing into the drainage main 10, the drainage mainly flows in parallel with the axis 19 of the straight pipe portion 12a, and this axis 19 has an acute angle with the axis 18 of the drainage main 10 as described above. They intersect at an angle α.

Therefore, the momentum M of the drainage when flowing into the drainage main pipe 10
Is a component M1 = si directed inward in the radial direction of the drain main 10.
n α and the component M2 = co toward the downstream side of the drain main 10 in the axial direction
When decomposed into s α and m, the axial component M2 does not become zero and always takes a positive value.

The momentum component M2 has a function of urging the drainage flowing into the drainage main pipe 10 in the drainage main pipe 10 to the downstream side in the axial direction thereof.

Therefore, the drainage flowing into the drainage main pipe 10 can effectively entrain the non-fluid substance contained therein in the B direction even when the flow rate thereof is relatively small.

(Effect of the Invention) As is apparent from the above description, according to the present invention, even if the flow rate of the wastewater discharged from the toilet of the piping unit with a toilet is relatively small, the non-fluid substance is accumulated in the drain main. do not do. Therefore, the amount of water required for flushing the toilet bowl can be set small. Further, since the front end of the joint member is provided with a flange portion formed in a funnel shape toward the front, and the flange stopper is interposed between the outer peripheral surface of the flange portion and the front surface of the panel member, the flange portion is large. When connecting to the drain of the toilet bowl, it can be connected without the need for accurate alignment, and construction is easy.
