The present invention relates to an elbow pipe for plumbing, and more particularly, to a structure of a low noise elbow pipe (Elbow pipe fitting) for the toilet to reduce the drainage noise of the toilet.

In general, the vibration and noise of the pipe are caused by the abnormal pressure generated by the water hammer action of the valve operation in the water supply and drainage system of the house.

Water hammering action means that when the flow of the flow control valve is suddenly closed and opened or the pump is started and stopped, the abnormal pressure flow of the fluid flowing in the pipeline rapidly changes, and the pressure in the pipe rises rapidly. The phenomenon of reciprocating in the pipeline occurs.

This action is called water hammer or water hammer, and water hammer in pipelines is the main cause of vibration and noise in pipes, causing pipe breakage, breakage of accessories and instruments, leakage of joints, etc. It will reduce the service life.

1 to 6, the structure of the low noise elbow pipe for toilet according to the present invention is the inlet pipe 10 through which fluid is introduced during drainage, the discharge pipe 20 is discharged through the inlet pipe 10, The inlet pipe 10 and the discharge pipe 20 is inserted into and fixed to the elbow-shaped body 30, the inside of the main body 30 is installed and fixed, the inside of the inlet 42 and the outlet while forming a curved surface (44) is in communication with, and the drainage connection pipe consisting of a sound absorbing pipe (40) for suppressing the drainage noise of the fluid introduced through the inlet pipe (10), the inner bottom surface of the sound absorbing pipe (40) A streamline portion 46 protruding upwardly at intervals is formed, and the inner ceiling surface opposite to the streamline portion 46 is rounded.

In general, the sound environment problems that occur in MDUs are mainly caused by the floor impact sound between the upper and lower floors and the noise of the drainage equipment.

Among them, the drainage of the water supply and drainage equipment, in particular, the drainage noise drained through the toilet or bath or wash basin, is mainly generated in the drainage pipe to which the present invention is applied. It serves to send filthy water and filth to a septic tank not shown.

Such drainage connection pipe is installed between the cross-sectional defects of the concrete when the sleeve is installed to minimize the noise of the sewage transmitted.

Again, the drain connection pipe is equipped with an inlet pipe 10 for guiding the sewage flowing downward.

The inlet pipe 10 applied to the present invention has a soundproof space 12 filled with an air layer between the double pipes in the form of a double pipe, and the air layer is soundproof to block the noise of sewage flowing into the inlet pipe 10. It serves as, combined with the body 30 to be described later.

Since the lower end 14 of the inlet pipe 10 coupled to the main body 30 should be firmly coupled to the main body 30, the present invention applies a key 14a for fixing while preventing rotation with the mating partner. .

This overcomes the disadvantages of screwing, which is a commonly applied coupling method, to prevent distortion of the counterpart due to torsional stress generated during screwing.

Particularly, although only one embodiment, in the present invention, four keys 14a are provided on the outer circumference of the lower end 14, and are bonded by using an adhesive such as a bond with a counterpart in order to further solidify the coupling. That is, after the key 14a is used for positioning and basic engagement with the opponent, the bonding with the opponent is completed by bonding.

On the other hand, at the bottom of the lower end 14, the sound insulation groove 14b to be coupled to the sound absorbing pipe 40, which will be described later, is formed in an annular intaglio shape, which blocks the contact with the external air layer to generate the sewage. It acts to double the noise.

That is, the leakage space is formed by the distortion caused by the conventional screw fastening, and prevents the leakage of sewage or the noise of the sewage generated by the leakage space in advance.

Subsequently, the main body 30 into which the aforementioned inflow pipe 10 is inserted is integrally formed with an inflow pipe guide surface 32 for guiding the lower ends 14 of the inflow pipe 10 to be fitted together. The inlet pipe guide surface 32 into which the inlet pipe 10 is inserted is formed with a key fixing groove 34 which serves to fix the above-described key 14a and then the outlet pipe 20 is inserted. The key fixing groove 34 described above is not formed on the guide surface.

On the other hand, the inlet pipe 10 and the discharge pipe 20, the inlet pipe guide surface 32 and the discharge pipe guide surface 32a of the insertion groove 32b to be coupled to the sound absorbing pipe 40 to be described later to a predetermined depth, preferably It is formed deeper than the inserted counterpart.

The side of the main body 30 is formed with an air jacket 36 which is opened into the main body 30, the air jacket 36 serves to block the generated sewage noise double, in particular, is opened inside The noise is induced into the space, which finally blocks the noise.

Such a main body 30 is equipped with a sound absorbing tube 40 for blocking the drainage noise of the sewage, and the inlet 42 and the discharge port 44 communicate with each other so that the sewage flows. .

The inlet 42 is formed with a flange portion 42a which serves as sound insulation while being coupled with the main body 30, and a skirt end 42a 'is formed outside thereof to insert the main body 30 described above. It is fixed after being inserted into the groove 32b.

In particular, as shown in detail in FIG. 1, it can be seen that the insertion groove 32b is formed deeper than the skirt end 42a ', and in particular, where the inlet 42 and the flange portion 42a intersect with each other. It can be seen that the lower end 14 of the inlet pipe 10 meet with each other to form a streamlined curved surface, where the discharge port 44 and the discharge pipe 20 intersect the drain guide stage extending downward at a gentle angle ( It can be seen that 44a) is integrally formed.

This shape is to smooth the flow of sewage, and to minimize the friction with the pipe to serve to block the drainage noise.

In particular, the cylindrical inner surface of the inlet pipe 10 is characterized in that formed in the shape of the nozzle narrowed toward the lower portion 14, which is to facilitate the flow of the above-described wastewater to the inlet port 42 of the sound absorbing pipe 40 ) And a streamlined connection.

After the main body 30 and the sound absorbing pipe 40 are combined with each other, the lower end 14 of the inflow pipe 10 is inserted into the discharge pipe guide surface 32a of the main body 30 to insert the key 14a of the inflow pipe 10. When inserted into the key fixing groove 34, the flange portion 42a of the sound absorbing pipe 40, which is mounted in advance, is in intimate contact with the bottom surface of the lower end portion 14 described above.

At this time, in the flange portion 42a of the sound absorbing pipe 40 according to the present invention, the soundproof soundproof projection 42b connected integrally protrudes in an annular shape, and the soundproof groove formed in the lower end 14 of the inflow pipe 10 ( 14b), and its role is as described above.

Again, the inner bottom surface of the sound absorbing pipe 40 is formed with a streamline portion 46 protruding upward at intervals, and the upper surface 46a of the streamline portion 46 is formed in a narrow circular surface. , The contact with the inner bottom surface is rounded and connected to the upper surface 46a.

Here, the width W of the streamline portion 46 is preferably a streamlined shape that becomes wider toward the discharge port 44, the reason for forming the streamlined streamline portion 46 is that flows through the inlet pipe 10 To facilitate the flow of sewage, in particular to reduce the friction between the sewage and the sound absorbing pipe 40 to minimize the drainage noise of the sewage.

The streamline portion 46 is preferably arranged in a plurality of predetermined intervals on the inner bottom surface.

On the other hand, the inner ceiling surface opposed to the streamline portion 46 is rounded, so that the sewage flows down from the rounded place to flow back to the inner ceiling surface serves to finally discharge to the discharge port (44). Therefore, it is possible to prevent splashing of sewage, which has been pointed out as a conventional problem, thereby reducing drainage noise.

Subsequently, a double pipe type discharge pipe 20 is mounted on the bottom surface of the drain guide end 44a of the discharge port 44 and inserted along the discharge pipe guide surface 32a extending in the longitudinal direction of the main body 30.

In the discharge pipe 20, a packing 22 for sealing the air layer inside the double pipe is inserted into the front and rear ends, which are inserted along the discharge pipe guide surface 32a and then closely adhered to the flange portion 42a of the sound absorption pipe 40.

At this time, the flange 42a in close contact with the discharge pipe 20 does not have a soundproof protrusion 42b, and the above-described drainage guide stage 44a protrudes.

As can be seen in the above configuration, it is possible to more completely seal the inside and outside of the discharge pipe 20 by the double pipe, the packing 22 and the like.

 The discharge pipe 20 inserted along the discharge pipe guide surface 32a extending in the longitudinal direction is again formed on the screw protrusion 32c formed on the upper side of the discharge pipe guide surface 32a and the cap 50 tightened along the screw protrusion 32c. It is firmly tightened to the discharge pipe guide surface 32a.

On the other hand, in order to more tightly seal between the sound absorbing pipe 30 and the discharge pipe 40, an O-ring 60 is installed between the discharge pipe guide surface 32a and the cap 50, and an adhesive such as a bond is used for each joint. To make the bond more solid.

Next will be described in detail the soundproofing effect due to the structure of the present invention and the flow of sewage flowing along the low noise elbow pipe for the toilet.

First, when the drain lever of the toilet shown in the toilet is not shown, the sewage of the toilet rapidly down the pipe leads to the inlet pipe 10 according to the present invention.

Sewage reaching the inlet pipe 10 of the double pipe type according to the present invention flows to the lower end 14 of the inlet pipe 10 while the drainage noise is blocked by the characteristics of the double pipe.

As described in the above-described configuration, the lower end portion 14 is formed in the form of a nozzle and is connected to the continuous sound absorbing pipe 40 in a streamline to naturally induce the flow of sewage.

The sewage induced in this way continuously flows to the rounded portion 46 of the sound absorbing pipe 40 and the curved surface of the inner ceiling surface and is drained without forming a rapid turbulence. Is reduced.

Sewage passing through the sound absorbing pipe 40 flows back to the discharge pipe 20, and the discharge pipe 20 applied to the present invention is also formed as a double pipe or a low noise pipe to further reduce the drainage noise.

Furthermore, in the present invention, various packings 22, O-rings 60, and the like are applied to the joints of the pipes to maintain the airtightness inside the pipes, and also reduce the drainage noise of wastewater flowing into the pipes due to the airtightness.

That is, as will be clear from the electric description, the present invention provides an improved low noise elbow pipe structure for toilet bowls to provide a plumbing facility that can block drainage noise when draining sewage.

This invention can be implemented in other various forms, without deviating from the mind or main characteristic. For this reason, the above-described embodiments are merely examples in all respects and should not be interpreted limitedly. The scope of the present invention is shown by the scope of the claims, and is not limited by the specification text. Again, all variations and modifications belonging to the equivalent scope of the claims are within the scope of the present invention.

On the other hand, the elbow pipe pipe used in this specification is used in the broadest sense, that is, to refer to a system such as a curved pipe that is widely applied to all pipes, and does not merely limit the elbow pipe pipe that is applied only to the toilet bowl.

As described in detail above, according to the structure of the low-noise elbow pipe for toilet according to the present invention, by combining the inlet pipe 10 and the main body 30 with the key (14a) to minimize the distortion during the coupling to reduce the drainage noise The effect is generated, the soundproof protrusion 42b is integrally formed in the sound absorbing pipe 40 to double the drainage noise, and the streamline portion 46 is formed inside the sound absorbing pipe 40 to drain the water flowing into the turbulent flow. By laminar flow, drainage noise can be significantly reduced. This produces the effect of completely blocking the drainage noise has the effect of significantly improving the product reliability of the pipe.
