Description

[Detailed explanation of the invention] This invention is a drainage trap designed to receive wastewater from the top and sides, and prevents it from overflowing into the drainage inlet at the top even if the wastewater flows in rapidly from the sides. At the same time, it forms an effective water seal.

As is well known, in a bathroom, there are separate drains from the bathtub and washing area.

Install traps individually in these drainage system channels to drain water,
You may also try to prevent odors from flowing back through the drain pipe.

However, in this case, a plurality of traps must be installed, and each trap is required for each drainage system, resulting in considerable economic waste.

Conventionally, therefore, a bathroom drainage trap has been proposed that receives washing water from the top and bathtub water from the side.

However, since the water level of the bathtub wastewater is high, it may suddenly flow into the trap from the side and overflow into the washing area inlet at the top.

In order to prevent such drawbacks, it has been proposed to reduce the diameter of the bathtub drain pipe immediately before the drain trap.

However, in this case, it will take a long time to drain the bathtub.
Efficient drainage cannot be expected.

Also, if the drain trap is long enough to accommodate the force, it is possible to install a water seal inside the trap to prevent odors from flowing back from the piping, but if the underfloor part is short, such as in a bathroom, the height will inevitably increase. Short-length drain traps must be used.

In this case, a sufficiently effective odor-preventing water seal cannot be formed within the trap.

This invention was proposed in view of the above, and has a water seal that prevents drainage from overflowing into the drainage inlet at the top even if it suddenly flows in from the side, and also prevents odor from flowing back from the piping section. The purpose of the present invention is to provide a drainage trap with a water trap provided inside.

The present invention will be described below with reference to the illustrated embodiment. A drain trap 1 according to the present invention includes a cylindrical trap frame 2 with an open top and a lid frame 3 attached to the open top of the trap frame 2.

The trap frame 2 has a partition wall portion 4 rising from the bottom surface to the middle of the height on the inside side, and the trap frame 2 is separated by the partition wall portion 4.
A water-sealing part 5 and a water-flowing part 6, each of which is open at the top, are constructed inside.

A drain pipe connecting portion 7 provided above one side of the trap frame 2 is communicated with the water flowing portion 6 through a through hole 8.

On the other hand, on the lower side of the outer surface of the trap frame 2, for example, a connection part 9 for a connecting pipe with a bathtub drain is provided.

According to the embodiment shown in the drawings, two connecting portions 9 are provided on the outer periphery of the trap frame 2 so as to face each other in the radial direction, and both connecting portions 9 are substantially perpendicular to the drain pipe connecting portion 7.

The side surface of the trap frame 2 in each connection part 9 is the fifth
Although it is closed as shown in the figure, the connection part 9 and the water sealing part 5 can be made to communicate with each other by opening one or both at the construction site.

A rectifying section 10 is provided on the inner surface of the trap frame 2 so as to face the connecting section 9.

The rectifier 10 is shown as an arcuate surface 11 that is perpendicular to the side surface of the trap frame and gradually rises from the connecting portion 9. Since there are two connecting portions 9, the two arcuate surfaces 11 are mountain-shaped.

Therefore, if the connecting part 9 is on either side, the rectifying part 1
0 may be one arcuate surface 11 that gradually rises from the connecting portion 9.

On the other hand, the lid frame 3 is provided with an annular lid plate 12 having an outer brim shape at the upper end of the vertical conduit 12, and the outer peripheral edge of the lid plate 13 is screwed onto the open upper surface of the trap frame 2 to make it watertight. Can be fixed.

When the lid frame 3 is fixed to the trap frame 2 as described above, the lower part of the conduit 12 is located inside the water sealing part 5 and the opening lower end 14 approaches the bottom surface of the trap frame 2, so the seal is closed. The water part 5 becomes an annular space part by the conduit 12.

In order to use the drain trap constructed as described above for draining water from a bathtub or washing area in a bathroom, the opening top of the trap frame 2 should face the washing area, and the sides of the trap frame 2 should be opened to seal the water. Any of the connecting parts 9 communicated with the part 5 and the drain of the bathtub are connected by a connecting pipe (not shown), and the connecting part 7 is connected to a drain pipe (not shown).

Therefore, regardless of whether the drain of the bathtub is on the right side or the left of the drain trap, by connecting the drain of the bathtub to one of the opened connecting parts 9, the drain of the bathtub can be easily connected to the drain of the drain. Can be linked.

Also, by using both connections, the drain trap can receive waste water from two locations on the sides.

When the drain trap is installed in this way, the upper end opening of the conduit 12, which is the upper opening of the trap frame 2 and receives the waste water from the washing area, becomes the upper drain inlet 15, and either one or both of the connections are connected. Pipe connection 9 is connected to side inlet 16
becomes.

No matter which of the inlet ports 15 and 16 the waste water flows into, the waste water accumulates in the water sealing part 5, enters the water flow part 6 by overflowing from the partition part 4, and is discharged from the drain pipe connecting part 7.

Therefore, since water is always stored in the drain part 5, the upper inlet 15 and the side inlet 16 are closed, so that the odor from the drain pipe does not flow back into the bathroom.

When the waste water flows in from the upper inlet 15, the waste water is collected in the water flow part 6 from the water sealing part 5 and is quickly discharged from the connecting part 7.

On the other hand, when a large amount of wastewater suddenly flows in from the connecting part 9, the wastewater flows back through the water sealing part 5 through the conduit 12, but a part of it jumps upward by the rectifying part 10, and the lower surface of the cover plate 13 The water enters the flowing water section 6 and is discharged from the connecting section 7.

Therefore, even if the water level in the bathtub is high and wastewater from the bathtub suddenly flows in from the connection part 9, the wastewater will be quickly discharged to the connection part 7 without being affected by the resistance of the water accumulated in the water sealing part 5. The water accumulated in the water sealing part 5 does not rise up the conduit 12 and overflow into the upper introduction port 15.

As described above, according to the present invention, although the structure is extremely simple, it is possible to quickly discharge the wastewater flowing in from the upper inlet and the side inlet, and in particular, the wastewater flowing from the side inlet can be rapidly discharged. Even if it flows in, it can be reliably discharged without overflowing to the upper inlet.

And since the overall height can be made sufficiently short, it can be installed in any location, and is most effective in places where the space under the floor is narrow, such as a bathroom unit, and it can be used to drain water from the bathtub for a short time. It can be discharged with
