Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in floor drainage equipment in sanitary facilities.

BACKGROUND OF THE INVENTION Conventionally, belt traps and the like as shown in FIG. 1 have been widely used as floor drainage equipment for floor drainage in toilets, bathrooms, etc. of buildings.

These structures are fixed by inserting the peripheral edge part 3 of the inverted arm part 2 halfway into the water seal 1, and the water flowing in from the perforated plate part 7A covered in the upper part is absorbed into the arm part. The water flows into the seal 1 along the outer edge of the arm 2 and flows under the peripheral edge 3 of the arm 2 (>”
It further rises along the wall of the water sealing part 4 and reaches the upper edge 5 of the water sealing part.
It was constructed so that it flows down into the drain pipe 6 beyond the drain pipe 6.

However, because the above-mentioned belt trap divides the flow path of the drain trap section into concentric circles, the intervals between the flow paths are narrow, and they are easily blocked by foreign objects, which forces managers to perform frequent cleaning work. In order to avoid the complexity of cleaning work, the mechanical parts of the internal trap were removed, which resulted in odors flowing back into the exhaust pipe.

In addition, the S and P type traps in conventional floor drainage equipment,
This was adopted to correct the shortcomings of the above-mentioned belt trap, but the narrowing of the flow path in the trap section was corrected, and depending on the piping situation, the trap section could be much lower than the floor level. In such cases, it is very difficult to clean the precipitate inside the trap, so an improvement has been desired.

The present invention improves the drawbacks of the conventional floor drainage equipment mentioned above, allows for smooth floor drainage in the channel without being blocked by inflowing garbage, sediment, etc., and provides the self-cleaning function necessary for floor drainage equipment. The purpose is to provide a fully satisfactory floor drainage device.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4 of the accompanying drawings.

Fig. 2 is an exploded perspective view of the present invention, Fig. 3 is a vertical sectional view, and Fig. 4 is a longitudinal sectional view of the present invention.
The figure is a cross-sectional view.

The floor drainage device of the present invention is formed of a perforated plate part 7 into which waste water is fed and a body part 8, and a drainage guide pipe 9 having a hanging small diameter part 9A and an inclined part 9B is attached to the perforated plate part 7. There is.

The inside of the body part 8 is divided by a partition weir 10 into a water sealing part 11 and a drainage drainage channel 12, and a drainage pipe 13 is connected to the terminal of the drainage drainage drainage channel 12 by a connection socket 14. There is.

The area of the horizontal cross section of the body 8 partitioned by the partition weir 10 is approximately 1/3 of the sealing section 21 & wastewater drainage channel, as shown in Figure 4. A hanging small-diameter portion of the drainage conduit 9 having a cross-sectional area of approximately 1/3 is inserted therein.

Therefore, the horizontal section inside the body part 8 is divided into three approximately 1/3 parts by the fan-shaped portions of the drain pipe 9 and the drain flow sewage water channel 12 that is not occupied by the drain pipe 9 of the water sealing part 11. There is.

As mentioned above, the shape of these waterways is fan-shaped, so the aspect ratio of the cross section is close to 1, so each waterway has a sufficient width compared to narrow waterways that are divided into concentric circles such as conventional belt traps. Because of this, it is not blocked by inflowing garbage, sediment, etc., and the drainage inside the flow path (hydrodynamically, as the frictional resistance value can be greatly reduced compared to conventional products). Movement is also very streamlined, and the self-cleaning function required for this type of floor drainage equipment can be fully satisfied.

As described above, this invention does not have to worry about the trap being frequently blocked like in conventional products, and the administrator is freed from the frequent cleaning work, so there is no need to worry about the trap mechanism being destroyed by the administrator. .

As a result, it is now possible to solve the problem of the floor drainage equipment being the source of bad odor in the toilet, and the problem of misidentifying the source of the odor and discharging a large amount of flushing water. can be well maintained, resulting in an extremely excellent floor drainage device.
