Description

[Detailed description of the invention] (Subject of invention, field of industrial application) The invention is used in the field of drainage equipment.

The present invention relates to a drainage basin that integrates a drainage basin and a trap.

(Prior art and its problems) Conventionally, a so-called circular plate, which is a disk with a required number of holes, was installed at the drain in the washing area of a bathroom in order to separate wastewater from wastewater such as hair. It was used. However, because insects and bad odors are coming up from sewage, in recent years traps with insect- and odor-proof measures have been used.

However, traps have the following problems.

(b) If the drainage efficiency is poor and the amount of drainage is a little large, or if hair accumulates in the round tray, drainage will quickly become stagnant.
The area around the drain outlet is filthy as wastewater overflows.

(b) Since the trap is installed in the corner of the washing area,
The entire floor of the washing area had to be sloped toward the separation device, which took a lot of time during construction, and if large floor tiles were used, it would be difficult to create this slope, so tiles were used.

The dimensions are inevitably small.

The present inventor developed a drainage basin in which drainage water does not accumulate in the washing area even if a trap is used, and which makes it easier to slope the washing area and use large tiles for the floor.
This has already been proposed in No. 6688 and other publications.

However, since the trap must be attached to the drainage folding body, not only is this time-consuming, but there is also the risk of water leaking between the drainage folding body and the trap.

(Objectives of the present invention) The objects of the present invention are: (a) To eliminate the trouble of separately attaching a trap during construction by integrally molding a trap case to the drainage folding body; (b) Between the drainage basin and the trap. This system provides drainage basins for the purpose of preventing water from leaking from.

(Structure of the Invention) In the present invention, a trap case is integrally molded at the drainage position of the bottom plate of a drainage folding body of a required length with an open upper part.
The trap case is a drainage basin with a built-in trap body.

The drainage folding body and trap case are made of metal plate, plastic, ceramics, etc. Moreover, the depth of the drainage basin body is arbitrary, and it is also arbitrary to attach a lid to the drainage basin. The structure of the trap body is not limited as long as it has the function of preventing bad habits and insects from coming up from the sewage.

(Example) The present invention will be explained in more detail based on the example shown in the drawings.

FIG. 1 is a partially cutaway perspective view, and FIG. 2 is a sectional view showing a first embodiment of the trap portion.

Reference numeral 100 denotes a drainage folding body, which is formed into a rectangular parallelepiped of a required length with an open top, and a flange 110 that is flush with the floor of the washing area is formed at the periphery of the opening.

The bottom plate lot of the drainage folding body 100 is sloped from one side to the other in the length direction, and a trap case l is integrally formed at the sloped end. Further, a step portion 104 is formed on the side wall of the drainage folding main body 100, and a lid 200 having a support leg 21 is placed on the first step portion 104.

The lid 200 that is placed over the drain folding body lOO is made of a metal plate, plastic, ceramics, or the like. In addition, the drainage folding body 1
A step may be provided in the opening of 00 so that a flat lid can be placed thereon.

A required number of drainage holes 22 are formed in the drainage folding body 100 so that the drainage water flows into the drainage folding body 100, and a finger hook 23 is formed on the edge so that it can be easily removed from the drainage folding body 100. In the case of the lid 200 of this embodiment, it will not come off or deform even if a person rides on it and puts weight on it.

Next, the trap case and trap body will be explained.

There is a drain port 11 approximately in the center of the bottom 12 of the trap case 1.
is formed, and the drain port 11 has a drain pipe (not shown).
Attachment flanges llO and ill are formed to allow attachment of drain pipes of different diameters.

A required number of ribs 14 are formed from the bottom 12 to the side wall 13 of the trap case 1, and the inner edges of the ribs 14 are shaped to fit with the outside of the bowl-shaped body 2.

The bowl-shaped body 2 is removably placed on the rib 14.

The outer diameter of the bowl-shaped body 2 is smaller than the inner diameter of the trap case 1, and a water passage 15 is formed between the bowl-shaped body 2 and the trap case 1.

Further, the rib 14 may be formed on the outside of the bowl-shaped body 2, and in this case, when the bowl-shaped body 2 is taken out, the trap case 1
Cleaning is easy because there are no protrusions inside.

A partition tube 3 having an outer diameter smaller than the inner diameter of the bowl-shaped body 2 is inserted into the bowl-shaped body 2 in a suspended state so that its tip does not come into contact with the inner bottom 20 of the bowl-shaped body 2. It is. A water passage 25 is thus formed between the bowl-shaped body 2 and the partition tube 3.

In addition, if the partition tube 3 is inserted with the tip thereof in contact with the inner bottom 20 of the bowl-shaped body 2, a water passage hole for water passage must be formed at the tip of the partition tube 3. be.

A mounting step portion 4 is formed in the upper part of the trap case 1. The mounting step portion 4 has a hanging flange portion 31 at the upper peripheral edge.
A round plate holder 5 having a round plate holder 5 formed thereon is mounted, and a partition tube 3 is removably fitted into a storage part 51 of the round plate holder 5 so as to be suspended within the trap case 1.

Further, a rounder 7 is removably placed in the upper opening of the partition tube 3.

In this embodiment, a small-mesh round tool is used to prevent sand, mud, hair, human body scum, etc. from settling in the trap case l as much as possible, but a normal round-mesh tool can also be used.

This embodiment operates as follows. The wastewater that has entered the drainage basin main body 100 enters the rounder 7. The waste water entering from the rounder 7 passes through the partition tube 3 and once enters the bowl-shaped body 2, and then overflows from the bowl-shaped body 2 and flows into the trap case 1, and is drained into the drain port 11.
water is drained from the water.

When the inside of the trap case 1 becomes dirty or dust accumulates, remove the rounder 7 and close the partition tube 3. If the bowl-shaped body 2 is taken out, the inside of the trap case l can be easily cleaned.

Also, is it a bowl-shaped body in a cold region? If the drainage water inside is about to freeze, just take out the bowl-shaped body 2 from the trap case l and throw away the drainage water inside. Furthermore, if you do not need the bowl-shaped body 2, just remove the bowl-shaped body 2 and the drainage will be normal. Can be used as a tool.

In addition, the drain port may be formed on the side 5113 of the trap case 1 as shown by the imaginary line A to lower the overall height of the trap 1. In this case, the drain port may be formed above the lower end of the partition tube 3. If provided, the trap case l will perform the function of the bowl-shaped body 2, and the bowl-shaped body 2 will become unnecessary.

In the case of the structure of the trap case and trap body shown in this embodiment, (1) Since the partition tube does not protrude from the bottom of the trap case part, it does not get in the way during cleaning and cleaning is easy.

(2) Even when water accumulates inside the trap case, the water inside the trap case can be easily drained, so that the drainage water does not freeze inside the trap case and the drainage function is not lost.

(3) The smooth meandering of the drainage water flow allows for good water flow, thus creating a self-purifying power of the trap itself.
Sand, dirt, hair, human bodies, etc. do not settle in the trap case, and the drainage flow is smooth.

(4) Parts can also be used in the horizontal pulling method.

(5) Although the reason is not clear, siphon phenomenon is less likely to occur.

It has the following effects.

FIG. 3 is a sectional view showing a second embodiment of the trap body.

A partition tube 50 is provided upright from the bottom 120 of the trap case l, and a bowl body 40 having an outer diameter smaller than the outer diameter of the trap case 1 is placed in the partition tube 50 so as to have a gap between the bowl body 40 and the partition tube 50. It is crowned with The bowl body 40 is fixed to the back side of a perforated plate 70, and the perforated plate 70 is placed on the periphery of the trap case 1.

It should be noted that the present invention is not limited to the above-mentioned embodiments.
For example, the bottom plate 12 has an inclination toward the center, and the bottom plate 12
Numerous modifications are possible within the scope of the claims, such as forming the trap case 1 in the central part.

(Effect of the invention) The present invention produces the following effects.

(a) A trap case is integrally molded at the water collection position on the bottom plate of the drainage basin body of the required length with an open top, and the trap body has a built-in trap body, so a drainage trap must be installed separately during construction. No need to attach it.

(b) Since there is no connection between the drainage basin and the trap, water leakage does not occur between the drainage basin and the trap.
