Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a drainage basin with a trap.

[Conventional technology and its issues]

For example, traps are used to prevent insects and deodorize drains on the floor of bathroom washrooms. Using this trap will reduce the drainage efficiency of the washing area floor.
For this reason, if the amount of drainage is a little large, or if hair accumulates in the round plate, the drainage will quickly become stagnant.
The area around the drain outlet is filthy as wastewater overflows.

To overcome this drawback, a trap-equipped drainage basin in which a trap is attached to the bottom plate of a drainage basin with an open top has already been proposed in Japanese Utility Model Application Publication No. 59-76688. This drainage basin can solve the above problems.

By the way, at actual construction sites, drainage basins with traps are usually constructed as follows.

First, in the plumbing work, a drain pipe for discharging water to the outside of the bathroom is installed upward from under the floor based on the design.

Next, during the plastering work, concrete was poured in the wash area of the bathroom, and tiles were placed at a slight slope toward the drainage area to finish the wash area floor. A drainage basin will be installed during this construction.

This drainage basin installation work is carried out while adjusting the position and inclination of the drainage basin so as not to create an unnatural step or the like between the upper edge of the drainage basin and the tiled floor surface.

In addition, the tiles that are pasted on the washroom floor are placed with the joints of the tiles in mind so that the joints run beautifully and there are fewer cuts in the tiles. Be changed.

Furthermore, if a drain pipe that is supposed to be installed vertically from the ground is tilted, or if the plumbing work and plastering work are done separately, the drain pipe may not stand up at the location where the drainage basin is installed. There are also many.

For this reason, it is difficult to install a drainage basin as designed, and in many cases, it is necessary to interpose a connecting pipe between the trap drainage outlet and the drainage pipe to make these adjustments. In this case, if the connecting pipe is rigid, it will be difficult to adjust the position and inclination of the drainage basin, and it will be necessary to recreate the connecting pipe separately on site.

In other words, when installing a drainage basin, it is difficult to position the drainage basin as designed, and especially if the connecting pipe from the trap is rigid and difficult to bend, there is no flexibility. The drain outlet and drain pipe could not be connected and the construction had to be redone.

An object of the present invention is to provide a drainage basin with a trap that solves the above-mentioned problems.

[Means for solving problems]

The structure of the invention taken to solve the above problems and achieve the purpose is as follows.

That is, the present invention is a drainage basin that is buried in the floor of a bathroom washroom and allows drainage from the floor of the bathroom to flow in, and the drainage basin comprises: a drainage basin main body which is open at the top and has a drainage section formed in the bottom plate; A removable lid disposed at the opening of the drainage basin body, a trap provided in the drainage part through which wastewater from the drainage basin body flows in and is discharged from the drainage opening, and a concentric circle around the drainage opening of the trap. and a connecting pipe, one end of which is connected to the connecting socket of the trap and the other end of which is connected to a drain pipe installed under the floor. It is a flexible drainage basin with a trap.

Function During construction, if the installation position of the drainage basin needs to be moved from the designed position due to the grouting of the tiles, or if it is necessary to install the drainage basin at an angle to match the slope of the floor, etc. Even if there is
Since the connecting pipe can bend and bend freely, there is no problem in connecting it to the drain pipe.

Therefore, there is no need to worry about having to redo the construction because the connecting pipe and the drain pipe cannot be connected, unlike in the past.

In addition, there are cases where the drainage pipe is not installed underground or from abandoned concrete as designed, but it can be connected to the drainage pipe by bending and bending the connecting pipe, so it can be installed in the designed position. A drainage basin can be installed.

Further, since there are double connection sockets concentrically provided around the drain port of the trap, connecting pipes of different diameters can be attached.

〔Example〕

The present invention will be explained in more detail based on embodiments shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of a drainage basin with a trap according to the present invention, FIG. 2 is a cross-sectional view taken from FIG. .

Reference numeral 1 denotes the main body of the drainage basin, which is made of a metal plate, plastic, ceramics, etc., and is formed into a rectangular parallelepiped of a required length with an open top. A flange 11 is formed on the periphery of the opening of the drainage basin body 1, and is installed on the same plane as the floor of the washing area.

The bottom plate 12 of the drainage basin main body 1 is sloped from one side to the other in the length direction, and a drainage hole 13 serving as a drainage portion is formed near the sloped end. A cylindrical portion 14 is formed at the periphery of the drain hole 13 and extends downward. The lower end of the cylindrical portion 14 is bent inward to form a mounting flange 16. In the cylindrical portion 14, the inclined upper side 14a of the bottom plate 12 is formed long and the lower side 14b is formed short, and the mounting flange 16 is formed substantially parallel to the flange 11 of the drainage basin body 1. A trap 3 is attached to the mounting flange 16. A screw 18 is formed on the upper part of the inner circumferential surface of the outer cylinder 30 of the trap 3, and the tightening ring 3
A mounting flange 16 is sandwiched between the two. That is, the trap 3 is mounted substantially perpendicularly to the flange 11 formed on the upper edge of the catch basin body 1.

In the trap 3 having the structure according to this embodiment, even if water leaks from between the tightening ring 32 and the mounting flange 16, the water will flow into the trap 3 and will not leak anywhere else. Around the drain 31 of trap 3,
Connection sockets 310 and 311 are provided in double concentric circles. One end of the connecting pipe 200, such as a bellows pipe, is detachably attached to the connecting socket 311.
A socket 201 is attached to the other end of the connecting pipe 200 so that it can be inserted into a drain pipe 401 and connected.

Reference numeral 2 is the lid, which is made of metal plate, plastic, ceramics, etc. A support leg 21 is formed on the lid 2. The lower end of the support leg 21 is formed with an inclination matching the inclination of the bottom plate 12, so that the upper surface of the lid 2 is approximately at the same height as the upper surface of the flange 11 when attached to the drainage basin main body 1. The lid 2 is then fitted into the drainage basin body 1. The lid 2 has drainage water in the drainage basin body 1.
A required number of drainage holes 22 are formed to allow water to flow inward, and finger hooks 23 are formed at the edges to facilitate removal from the drainage basin main body 1.

In the case of the lid 2 of this embodiment, since it has the supporting legs 21, it will not be removed or deformed even if a person rides on it and the weight is increased. The supporting legs 21 do not need to span the entire height of the drainage basin main body 1, and if a step (not shown) that supports the supporting legs 21 is provided midway in the height direction of the drainage basin main body 1, the support legs 21 do not need to span the entire height of the drainage basin main body 1. It is good if the height is up to the top.

The structure of the drainage basin according to the present invention is not limited to the above embodiments. For example, the drainage basin main body has a bottom plate 1.
2 may have a structure in which the drain hole 13 is formed in the center of the bottom plate 12 with an inclination toward the center, and the lid may also have another structure.

The trap used in the present invention will be described in detail with reference to FIG.

The trap 3 has an outer cylinder 30. Outer cylinder 3
A drain port 31 is formed approximately at the center of the bottom portion 300 of 0. A connecting pipe 20 is installed around the drain port 31.
The connecting sockets 310 and 311 for attaching 0 are concentrically formed so that connecting pipes 200 having different diameters can be attached. Bottom part 30 of outer cylinder 30
A required number of ribs 34 are formed from the side wall 13 to the side wall 13, and the inner edge of the rib 34 is shaped to fit with the outside of the bowl-shaped body 40. and rib 3
4, a bowl-shaped body 40 is removably mounted.

The outer diameter of the bowl-shaped body 40 is smaller than the inner diameter of the outer cylinder 30, and a water passage 35 is formed between the bowl-shaped body 40 and the outer cylinder 30.

The ribs 34 form a water passage 35, and may be formed on the outside of the bowl-shaped body 40. In this case, when the bowl-shaped body 40 is taken out, the ribs 34 form a water passage 35.
Since there are no protrusions inside, cleaning becomes easier. Further, the ribs 34 may be formed on both the inner surface of the outer tube 30 and the outer side of the bowl-shaped body 40.

A partition tube 33 having an outer diameter smaller than the inner diameter of the bowl-shaped body 40 is inserted into the bowl-shaped body 40 in a suspended state so that its tip does not come into contact with the inner bottom 20 of the bowl-shaped body 40. It has been done. Then the bowl-shaped body 40
A water passage 25 is formed between the partition tube 33 and the partition tube 33 .

Note that the tip of the partition tube 33 is connected to the inner bottom 2 of the bowl-shaped body 40.
If the partition tube 33 is inserted in contact with the tube 0, a water hole must be formed at the tip of the partition tube 33.

A lower step portion 5 is formed on the lower side of the inner circumferential wall of the tightening ring 32 . The partition tube 33 is formed with a flange portion 312 protruding from the upper peripheral edge thereof, and the partition tube 33 is removably placed on the lower step portion 5 so as to be suspended within the bowl-shaped body 40. ing.

Further, a perforated plate 37 made of wire mesh is removably placed on the upper step portion 36 of the tightening ring 32.

The perforated plate 37 is made of a fine mesh plate to prevent hair, human body dirt, etc. from flowing into the plate. Note that perforated plates of other structures can also be used.

The trap 3 according to this embodiment operates as follows.

The waste water entering from the perforated plate 37 passes through the partition tube 33 and once enters the bowl-shaped body 40, then overflows from the bowl-shaped body 40, flows into the outer tube 30, and is discharged from the drain port 31.

When the inside of the trap 3 becomes dirty or dust accumulates, the inside of the outer cylinder 30 can be easily cleaned by removing the perforated plate 37 and taking out the partition cylinder 33 and bowl-shaped body 40.

In addition, if the drainage inside the bowl-shaped body 40 is likely to freeze in a cold region, if the bowl-shaped body 40 is taken out from the trap 3 and the drainage inside is thrown away, the drainage inside the bowl-shaped body 40 will freeze and no longer drain. Never.

Furthermore, when the bowl-shaped body 40 is not needed, it can be used as a normal drainage tool by removing the bowl-shaped body 40.

When installing the drainage basin according to this example, the installation position of the drainage basin may deviate from the designed position due to the grouting of the tiles during construction, or the drainage basin may be tilted to match the slope of the floor surface, etc. It may be necessary to locate the

Further, the drainage basin 401 may not be installed upright from the ground or from abandoned concrete as designed.

In this case, as shown in FIG.
is bent and connected to the drain pipe 401.

In addition, since connection sockets 310 and 311 for attaching the connecting pipe 200 are provided concentrically around the drain port 31, connecting pipes 20 of different diameters can be connected to each other.
Can be installed even with 0.

〔Effect of the invention〕

The present invention has the above configuration and has the following effects.

(1) During construction, the installation position of the drainage basin may deviate from the designed position due to the grouting of the tiles, or
It may be necessary to install the drainage basin at an angle to match the slope of the floor.

Even in this case, since the connecting pipe can bend and bend freely, there is no problem in connecting it to the drain pipe.

Therefore, there is no need to worry about having to redo the construction because the connection between the connecting pipe and the drain pipe cannot be established as in the past.

(2) Drainage pipes may not be installed upright from the ground or from abandoned concrete as designed.

Even in this case, since the connecting pipe can be connected to the drain pipe by bending and bending, the drainage basin can be installed at the designed position.

(3) There are double connection sockets concentrically around the trap's drainage port for connecting connecting pipes, so connecting pipes of different diameters can be installed.

In addition, in cases where a connecting pipe is not necessarily required, such as when a drainage pipe is installed upright from the ground or from abandoned concrete as designed, the connecting pipe may be removed and used.

In this case, since the trap has double connection sockets arranged concentrically, it can be connected to the drain pipe without the need for parts such as adapters even if the diameter of the drain pipe is not constant.
