Description

[Detailed description of the invention] The present invention relates to a trap placed in the middle of a pipe, and a trap body 1 having an upward opening 9 is provided with a plurality of inlets 2 and one outlet 3, and a funnel is provided in the upper opening 9. The water-sealing cap 11 has a lower end opening 11a connected to the outlet 3 of the trap body 1.
The pipe body 4 is located near the bottom 1b which is lower than the trap body 1, and the middle part of the pipe body 4 is bent downward to connect the plurality of inlets 2 and outlets 3 in the box-shaped trap body 1. The upper surface of 5 is lower than the lower surface of other parts of the tube body 4,
The inlet portion 6 of each tube body 4 is connected to each inlet port 2 of the trap body 1 in a watertight manner, and the outlet portion 7 of each tube body 4 is provided with a clearance from one outlet port 3 of the trap body 1. This relates to a trap that is connected to

Conventionally, as shown in FIG. 7, wash water and bath water are combined and drained through one trap body 1a, and this trap body 1a is used as a drainage system from the floor etc. ing.

However, in such a means, when a large amount of wash water and bath water are combined, there is a problem that they overflow from the trap body 1a to the floor surface.

The present invention was developed in view of this problem, and its purpose is to connect multiple inlets and one outlet separately with pipe bodies within the trap body, thereby allowing multiple points to be connected. At the same time, the drained water can flow directly into the drain pipe after the trap body without merging in the trap body, and this can suppress overflow from the trap body to other drainage systems, for example, to the floor surface. In addition, by connecting the outlet of the tube to the outlet of the trap body with a gap, and connecting the inlet of the tube to the trap body in a watertight manner,
A trap that prevents wastewater from other drainage systems that flow into the trap body from the floor etc. from flowing back into the washbasin and bath drainage systems, and guides the wastewater to the drain pipe after the trap body for secure drainage. Our goal is to provide the following.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 is a trap body that opens upward, and one side wall 8
It forms two inlets 2 on the side wall 8 and one outlet 3 on the other side wall 8.

A funnel-shaped water sealing cap 11 is attached to the upper opening 9 of the trap body 1, and the lower end opening 11a is connected to the bottom 1 of the trap body 1.
It is arranged so that it is located near b.

Then, a perforated plate 12 is placed on the opening step from above the water sealing cap 11, so that water can be drained from the floor surface into the trap body 1.

A drain pipe 15 is connected to the outlet 3 of the trap body 1.

In this way, the wastewater flowing in from the floor surface can be drained from the discharge pipe 15.

In this case, the lower end of the water sealing cap 11 protrudes into the waste water A stored at the bottom of the trap body 1 to prevent odor from reaching the floor surface from the drain pipe 15 side.

A sink drain pipe 13 from a washroom (not shown) is connected to one entrance 2, and a bath drain pipe 14 from a bathroom is connected to the other entrance 2.

Also, a large diameter drain pipe 15 is connected to the outlet 3.

In this way, wash water and bath water can be drained directly to the drain pipe 15 without merging in the trap body 1.

The washbasin drain pipe 13 and the bath drain pipe 14 are connected to the inlet 2 of the trap body 1 in a watertight manner with a gasket 16.

Then, the inlet part 6 of the pipe body 4 is externally connected to the drain pipe part protruding into the box-shaped trap body 1 in a watertight manner, and the outlet part 7 of the pipe body 4 is connected to the outlet part of the drain pipe 15 from the trap body 1. The outlet part 7 of the drain pipe 15 is made to face inside the drain pipe 15 by leaving a gap with respect to the drain pipe 3.

The tubular body 4 is bent downward in the middle in a U-shape, and the upper surface of the bent portion 5 is lower than the lower surface of other parts of the tubular body 4.

However, due to the waste water collected at the bending part 5 of the lever,
This is to prevent odor from flowing into the bus drain pipe 14 from the drain pipe 15 side after the trap body 1.

Similarly, odor does not flow into the washbasin drain pipe 13 from the drain pipe 15 side.

Furthermore, the waste water stored in the trap body 1 does not enter the inlets 7, 7 of the washroom drain pipe 13 or the bath drain pipe 14 and flow back.

FIGS. 3 to 6 a and b show other embodiments, in which FIG. 3 shows an example in which the outlet portions 7 of two pipe bodies 4 are connected to each other, and FIG. It is fitted externally into the opening 9 of the trap main body 1 via.

In Figure 5, the diameter of the drain pipe 15 after the trap body 1 is increased,
The drain pipe 15 is connected to the trap body 1 through the large diameter socket 18.
This increases the drainage capacity and shortens the drainage time.

FIG. 6a shows the water sealing cap 11 screwed into the trap body 1, and the figure shown in FIG.

As mentioned above, the present invention connects multiple inlets and one outlet within the trap body with separate pipe bodies, so water drained from multiple locations at the same time does not merge inside the trap body. This has the advantage that overflow from the trap body to other drainage systems, for example, to the floor surface, can be suppressed.

Furthermore, the outlet of the tube is connected to the outlet of the trap body with a gap, and the inlet of the tube is connected to the trap body in a watertight manner, so that other objects flowing into the trap body from the floor etc. This has the advantage that it is possible to prevent wastewater from the drainage system from flowing back into the washbasin and bath drainage systems, and to guide the wastewater to the drain pipe after the trap body for reliable drainage.
