Description

Drainpipe for Noise Prevention in Apartment Veranda

The present invention relates to a noise prevention device for an apartment veranda drain pipe, and more particularly to a noise prevention device for an apartment veranda drain pipe that can minimize the noise generated by the falling water by lowering the acceleration of the falling water falling through the drain pipe. .

In general, a multi-family house or apartment veranda is provided with a drain pipe for easily draining the sewage and rainwater from the upper floor to the lower floor or to drain the washing water during the cleaning of the porch. This conventional drain pipe structure is illustrated in FIG. 1. A through hole 2 is formed at an arbitrary position of the veranda 1 for partitioning each layer, and the connecting member 10 through which the upper and lower parts are penetrated is fitted into the through hole 2.

A plurality of drain holes 12 are formed on the upper side of the connecting member 10 to drain the washing water discharged from the veranda 1, and the locking jaw 14 is disposed on the upper and lower inner sides of the connecting member 10. 16 are formed, respectively.

One end of the drain pipe 18 having a shape of a through hole for discharging the falling water from the upper layer to the lower layer is fitted into each of the locking jaws 14 and 16.

In the conventional drainage pipe structure having such a configuration, the washing water discharged from the veranda 1 flows into the drainage pipe 18 through the drainage hole 12 of the connection member 10, or the sewage and rainwater from the upper layer drainage pipes. When falling to the lower layer through the 18 and the connecting member 10, when the acceleration of the falling water falling from the high floor falls freely to the lower layer, the acceleration gradually rises and the air remaining in the drain pipe 18 remains. As noise generated when passing air in the air and falling water passing through the drain pipe 18 collide with the inner surface of the drain pipe 18 are combined, the noise delivered to the room is further increased, thereby making the living life more comfortable. Indoor dwellers, who had to run for a while, became uncomfortable due to noise.

In addition, the noise due to the falling water is transmitted to the room at night, so that it is disturbed to take a sleep, so there is a problem that can not rest enough to accumulate fatigue.

The present invention was devised in view of the above problems, and its object is to reduce the acceleration of the falling water falling through the drain pipe, thereby providing a noise prevention device for apartment veranda drain pipe that can minimize the noise generated by the falling water. It is in

The present invention for achieving the above object in the configuration of the drain pipe for discharging the falling water from the upper layer to the lower layer, the first and second catching jaw is provided inside the upper and lower parts so that the upper and lower portions of the drain pipe are fitted. It is formed, and the main connection pipe provided with a plurality of drain holes on the outer surface; A first drainage induction pipe having a first inclined angle having a diameter smaller from the first catching jaw, and having a first drainage hole formed at a lower portion thereof; And a second drainage induction pipe having an upper end fixed to the connecting piece and having an inclination angle so as to increase in diameter downward from the upper part thereof, and having a second drainage hole while the outer diameter of the lower end is smaller than the inner diameter of the drainage pipe.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object in detail as follows. Of course, the same reference numerals are given to the same components as in the prior art.

As shown in FIGS. 2 to 3, a main connecting pipe 20 having a plurality of drain holes 12 formed on an outer surface thereof is inserted into the through hole 2 formed in the veranda 1. First and second catching jaws 22 and 24 are respectively formed at the upper and lower inner sides of the c) to allow one side of the drain pipe 18 to be fitted therein.

In addition, the first drainage guide pipe 30 having a smaller diameter in the downward direction from the first catching jaw 22 is formed to be inclined, and a plurality of connection pieces 34 are disposed below the first drainage guide pipe 30. This is provided. Of course, since the connecting pieces 34 are formed to have a predetermined interval, the first drain hole 32 is formed between the connecting pieces 34 so that the falling water can pass.

In addition, the upper portion of the second drainage induction pipe 40 is fixed to the connecting piece 34, the second drainage induction pipe 40 has an inclination angle so as to increase in diameter downward from the top, the lower end of the The second drain hole 42 is provided by making the outer diameter of the lower end portion smaller than the inner diameter of one drain pipe 18.

Referring to the process of minimizing the noise of the falling water falling free from the upper floor by the noise prevention device for the apartment veranda drain pipe of the present invention made in such a configuration as follows.

First, the washing water discharged from the multi-family house or apartment porch (1) or the sewage and rain water from the upper floor is introduced into the drain pipe 18 through the drain hole 12 formed on the outer surface of the main connecting pipe 20, the drain hole Dropping water passing through 12 is first hit the outer surface of the second drain guide pipe 40 provided inside the main connecting pipe (20).

As the falling water hit the outer surface of the second drain induction pipe 40 moves downward along the inclined surface of the outside, the acceleration that is dropped is reduced by the inclined surface, thereby reducing the noise.

In addition, the falling water moving downward along the inclined surface of the second drain induction pipe 40 to reach the lower end is a second formed between the inner diameter of the drain pipe 18 and the outer diameter of the lower end of the second drain induction pipe 40. As it passes through the drain hole 42 and falls through the inner surface of the drain pipe 18, noise is not generated while friction with air in the atmosphere in the drain pipe 18 does not occur.

The falling water dropped on the inner surface of the drain pipe 18 reaches the first drain induction pipe 30 provided on the inner upper part of the main connecting pipe 20 again, and reaches the first drain induction pipe 30. Since the falling water has the same action as that of the second drainage induction pipe () when moved downward along the inclined surface of the inner side, it is possible to eliminate the noise of the falling water.

In addition, the falling water reached to the lower end of the first drain induction pipe 30 passes through the first drain hole 32 formed between the respective connecting pieces 34 fixing the upper portion of the second drain induction pipe 40. It falls down while contacting the upper outer surface of the second drain induction pipe (40).

The falling water, which is moving downward from the upper portion of the second drainage induction pipe 40 through the first drainage induction pipe 30, may be washed water or rainwater introduced through the drain hole 12 of the main connection pipe 20. Although joined to be moved to the lower end of the second drain induction pipe 40, when the wash water or rain water does not flow through the drain hole 12 of the main connecting pipe 20, the second drain induction pipe 40 alone. After moving downward along the outer side of the, it is to minimize the noise generated during the fall of the falling water while repeating the process of falling back down the inner side of the drain pipe 18.

On the other hand, Figure 4 shows another embodiment of the present invention, by forming a plurality of guide grooves 50 having a predetermined interval on the outer periphery of the second drain guide pipe 40 in the downward direction along the inclined surface, When the flow of the falling water is driven in one direction when the falling water passing through the first drain hole 32 of the first drain guide pipe 30 falls on the upper side of the second drain guide pipe 40, a plurality of guide grooves ( 50) by inducing the falling water to fall evenly, so that the flow of the falling water is smoothed to minimize the noise.

As described above, the noise preventing device for the apartment veranda drain pipe according to the present invention has a plurality of drain holes formed on the outer side, and the main connection pipe having the first and second catching jaws so that one side of the drain pipe is fitted on the upper and lower parts thereof. And a first drainage induction pipe having an inclination angle of decreasing diameter from the first catching jaw downward and having a connecting piece and a first drainage hole at a lower portion thereof. The upper layer is fixed to the connecting piece, and has an inclination angle so as to increase in diameter downward from the upper portion, and has a second drainage induction pipe having a second drainage hole while the outer diameter of the lower end is smaller than the inner diameter of the drainage pipe. As the acceleration of the falling water falling from the fall decreases by the inclined surface and the falling water falls on the inner surface of the drain pipe, the noise generated in the drain pipe is drastically lowered, thereby relieving the inconvenience caused by the noise in the living environment. In addition, the noise of the falling water is not transmitted to the room at night, thereby having a comfortable sleeping effect.
