Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drain pipe joint used in domestic piping equipment for drainage or sewage such as wash basins, bathtubs, flush toilets, and sinks.

[Conventional technology]

Generally, when installing a bath unit, wash basin unit, sink unit, etc. in a tiled room in a hotel, condominium, or other apartment complex, the drainage from each appliance is led to the floor drain pipe, that is, the horizontal drainage pipe, through the fixture drain pipe, and then to each floor. U-shaped traps were installed in each of the drain pipes of the above-mentioned buses and other appliances in order to form a piping system that drained into a common drainage standpipe.

[Problem that the invention attempts to solve]

Therefore, in the conventional piping system, drainage from multiple appliances directly joins each other in the middle of the drainage horizontal branch pipe, causing mutual interference between the drainage pipes, increasing the drainage noise, causing concerns about the effect on the trap and backflow to the other appliance. It was hot. In addition, there is a risk of clogging the pipes due to hair and other foreign substances coming from the bathtub and other equipment, making cleaning difficult.In addition, rings, contact lenses, and other small valuables may fall into the drain pipes. There was an inconvenience in not being able to deal with loss accidents caused by the influx of people.

The present invention aims to easily solve these conventional problems, and can easily prevent clogging of drain pipes and accidents of losing valuables to drain pipes, and can also prevent increased drainage noise and traps. The object of the present invention is to provide a drain pipe joint that has a simple configuration and is inexpensive, which can reduce the influence.

[Means for solving problems]

In the present invention, a connecting pipe ₂ with a drainage inlet 1 is provided in the tangential direction of the cylindrical part of a drain pipe joint 5, which has a cylindrical part with an opening 5 ₂ at the top and a conical cylindrical part 5 1 at the bottom, and a drain pipe joint 5 provided with a connecting pipe 4 having a drain outlet 3 at the center of the lower part, the drain pipe fitting 5 having a connecting pipe 4 having a drain outlet 3 at the center of the lower part,
A dish-shaped screen 6 for collecting foreign matter is removably inserted into the cylindrical part of the pipe joint between the flow path between the flow path and the outflow port 3, and a cap-shaped cover is provided so that the screen 6 can be taken out of the pipe. 7 is provided in the opening 5 ₁ so as to be openable and closable, a cylindrical portion 6 ₁ is protruded from the center of the screen 6 to form an overflow 6 ₂ at the upper end, and a trap 8 is provided on the downstream side of the connecting pipe 4. This drain pipe joint is characterized by:

〔Example〕

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

In FIGS. 1 and 2, the drain pipe joint 5 is a cylindrical casing that has a conical cylindrical portion ₅₁ at the bottom whose diameter gradually decreases downward, and the cylindrical portion is connected to an appliance such as a wash basin. A connecting pipe 2 with a drainage inlet 1 is provided, and a trap 8 is provided at the lower end of the conical cylinder part ₅₁ via a connecting pipe 4 with a drainage outlet ₃ . A dish-shaped screen 6 for filtering inflow and wastewater is housed inside to collect foreign matter.

A plurality of connecting pipes 2 are protruded at appropriate intervals (equal or unequal intervals may be used), but in this example, two are provided with a phase difference of 180°, and one is provided in the middle. The drain pipe joint 5 is used as a drain collector. Each connecting pipe 2 consists of a horizontal pipe part on the protruding end side and an inclined pipe part slightly descending toward the drain pipe joint 5 side on the base side.
The drainage pipe is provided so that the drainage water flowing into the drain pipe flows in a slightly downward and substantially tangential direction, turns in the same direction within the drain pipe joint 5, and flows down.

The screen 6 is a porous member consisting of a conical cylinder part, a cylindrical part 6 ₁ , and an annular bottom between the lower ends of both cylinders, and has a removable dish-like structure in the conical cylinder part 5 ₁ of the drain pipe joint 5. has been completed. A flange is provided outwardly protruding on the upper edge of the conical cylinder part, and when the drain pipe fitting 5 is fitted into the conical cylinder part 5 ₁ , the flange locks the conical cylinder part 5 ₁ . The inner chamber of the cylindrical body of the drain pipe joint ₅ and the outlet 3 communicate with the inlets 1, 1, 1 with an appropriate gap formed between the conical cylindrical part 51 and the conical cylindrical part of the screen 6. It has a size that is interposed in the flow path between the two.

The cylindrical part 6 ₁ is open at both ends to form an overflow port 6 ₂ , but its height is higher than the flange and when the screen 6 is loaded into the drain pipe joint 5 of the connecting pipe 2 . It is formed lower than the opening to.

In the figure, 7 is a cap-shaped cover for an opening ₅₂ provided in the drain pipe joint 5, which is provided with a handle and is removably fitted. 9 is a handle of the screen 6, 10 is a mounting flange of the drain pipe joint 5, and 11 is a drain hole of the slab waterproof layer.

It should be noted that, in place of the conical tube part ₅₁ , a flat bottom part or a tilted bottom part tilted to one side may be used, or the cap cover 7 may be connected at a hinge part without being removed. Furthermore, trap 8 is U
It is also possible to choose to connect the shaped pipe trap to the connecting pipe 4 or to form it integrally therewith, or to make the drain pipe joint 5 have a built-in trap mechanism, such as a liquid seal chamber. Although the screen 6 is fixed depending on its own weight, a locking and fixing part may be provided.

Next, an example of installation work of the drain pipe joint 5 having the above-described configuration will be described.

In FIG. 3, the connecting pipes 2, 2, and 2 are connected to a wash basin A, a bath B, and a floor drain C via appliance drain pipes a, b, and c, respectively. Each of the drain pipes a, b, and c does not have its own trap, but is connected to a collecting drain pipe joint 5 that is piped as a collector. The trap 8 of the drain pipe joint 5 is connected to the drain standpipe e via the drain side branch pipe d, and the drain pipe f of the toilet D is independently connected to the drain standpipe e. Each pipe a, b, c, d, e has a nominal diameter of 40A,
50A, 50A, 80A, and 100A are used.

In the figure, g is a slab penetration part that requires waterproofing.

Therefore, the drainage water from the washbasin A, bath B, and floor drain C flows into the drain pipe joint 5, but even if it flows in all at once, it flows in a substantially tangential direction, forming a vortex flow and flowing smoothly. Also, the drainage noise is low.

In addition, hair and foreign matter that flow out with the drainage water are captured by the screen 6, and only the waste water that passes through the trap 8 flows out into the horizontal branch pipe d, so there is no blockage on the downstream side of the horizontal branch pipe d. Even if you lose valuables such as rings, they will be collected on screen 6.
Since the screen 6 can be removed from the drain pipe joint 5 and cleaned, maintenance is also extremely easy.

Comparing this example with a conventional example in which each device has a trap and directly merges into the lateral branch pipe,
In this example, the drainage from multiple appliances does not merge in the middle of the side branch pipe, so there is no interference between the drainage, and there is no need to worry about increased drainage noise or backflow into the drainage pipes of other appliances. . Furthermore, since traps for each of the drain pipes a, b, and c are not required, construction and maintenance are simple, and there is no influence on the traps caused by mutual interference between the drains. Furthermore, as already mentioned, hair and foreign matter that flow out from the equipment along with the drainage water are captured by the screen 6, so there is no chance that valuables will accidentally flow out into the side branch pipe or the vertical branch pipe. There is no blockage of the tube. Furthermore, since there is only one slab penetration part g, construction is easy, and since a trap larger than the original trap of the device is used, the characteristics of the trap can be fully exhibited.

As described above, the drain pipe joint 5 has a plurality of connecting pipes 2, 2...
Although we have shown an example in which one connecting pipe 2 is installed and used as a collective drain pipe, it is also possible to use one connecting pipe 2 as a drain pipe joint 5 unique to the appliance, or to provide a plurality of connecting pipes 2 and use one or any It is also possible to connect drain pipes to several connecting pipes 2 and close off the remaining portions with caps that can be opened and closed, so that the number of drain pipes can be increased or decreased.
