Abstract

PROBLEM TO BE SOLVED: To prevent shortage of sealing water or generation of involving sound of air on draining, by arranging a collision board with a gap between a wall face and the side face of a vertical pipe at an opposite position against the extended part of a horizontal pipe, in the inside of a right-angled cross joint. SOLUTION: A right-angled cross joint A constitutes a rightangled cross part where a horizontal pipe 1 joins a vertical pipe 2. A collision board 3 is erected in front of the wall face 5 on an stretched line of the horizontal pipe 1 of the right-angle cross joint A to form a gap 7 between the collision board 3 and the wall face 5. And hence, an air layer is formed at the gap 7 and the inside of the right-angled cross joint A and the inside of the drain pipe are always kept almost in the atmospheric pressure and a full stream in the pipe is prevented and a vacuum state generated in accordance with the falling stream of drain in the vertical pipe 2 is prevented. As a result, the shortage of sealing water or the involving sound of air is prevented in a trap connected to the horizontal pipe 1 or the vertical pipe 2.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention avoids the occurrence of water seal breakage and air entrainment noise during drainage by improving the shape of the joint pipe at the junction of the horizontal and vertical pipes of a drainage pipe in a house. It is configured as follows.

2. Description of the Related Art Conventionally, as shown in FIGS.
In a drainage pipe system of an apartment house, a ventilation pipe 13 and a ventilation valve 14 are generally provided so as to protrude from the drainage pipe as a means for preventing the drain trap from being completely sealed or generating air entrainment sound during drainage. I have. In the case of the configuration of the ventilation pipe 13, it was dealt with by opening the opening at the tip end to the outside atmosphere. Further, in the case of the configuration of the ventilation valve 14, a special ventilation valve 14 that opens only at the time of drainage is provided at the distal end instead of releasing the distal end of the ventilation pipe to the atmosphere. Also, make the drain pipe diameter larger than necessary,
Methods such as generating a full flow state in the pipe have been taken.
However, in the configuration in which the ventilation pipe and the ventilation valve are provided, a ventilation pipe and a ventilation valve as separate parts are required, which increases the labor and the cost of construction.

[0003]

In a house, any method such as providing a ventilation pipe or a ventilation valve, or increasing the diameter of a drain pipe has a considerable effect on indoor space. Problems arise from the design of the house. In addition, opening of the drain pipe to the outdoor atmosphere by the ventilation pipe
There was a problem of odor itself, and it was necessary to consider the relationship with the position of the window of the neighbor. The present invention is to improve the joint part of a conventional drainage pipe so that the same effect as when a ventilation pipe or a ventilation valve is attached can be expected. Further, the space for the ventilation pipe used in the prior art is not required, and the labor for piping work can be saved.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. In the orthogonal joint A interposed at the connection between the horizontal drawing pipe 1 and the vertical drawing pipe 2 of the drainage pipe of the house,
Inside the orthogonal joint A, a gap 7 is formed between the wall 5 on the side of the longitudinally drawn tube at a position where the extension of the horizontally drawn tube 1 faces, and the wall 5.
The collision plate 3 provided with is provided.

[0005]

Next, an embodiment of the present invention will be described. FIG. 1 is a side view showing a configuration in which an orthogonal joint A is arranged at a portion where a drain pipe from a toilet 8 on the third floor transitions from a horizontal pipe 1 to a vertical pipe 2, and FIG. 2 is a side view from a toilet 9 on the second floor. FIG. 3 is a side view showing a configuration in which an orthogonal joint A is disposed at a transition portion between the pulling tube 1 and the vertical drawing tube 2, FIG. 3 is a side view and a plan view of the orthogonal joint A of the present invention, FIG. FIG. 5 is a drawing showing a drainage pipe system of an apartment house in which a conventional ventilation pipe is arranged, FIG. 6 is a side view showing a configuration in which a conventional ventilation pipe is arranged, and FIG. 7 shows a configuration in which a conventional ventilation valve is arranged. It is a side view.

In FIG. 1, in a three-storey house,
A configuration in which both the toilet 9 on the second floor and the toilet 8 on the third floor are arranged is disclosed. The part where the drain pipe 12 of the toilet 9 on the second floor merges with the vertical drawing pipe 2 of the toilet 8 on the third floor is configured and merged as usual. And the orthogonal joint A which constitutes the main part of the present invention is composed of the horizontal pulling pipe 1 and the vertical pulling pipe 2 from the toilet 8 on the third floor.
It is located at the junction with

In FIG. 2, in a two-story house,
The configuration of the toilet 9 on the second floor is illustrated. That is, the horizontal drawing tube 1 extends from the toilet 9 on the second floor, and the horizontal drawing tube 1 is
The orthogonal joint A is interposed and arranged at a portion orthogonal to the above. A trap 15 is provided at a position below the orthogonal joint A, and a water seal is disposed inside the trap 15 so that a bad smell from the downstream does not return to the room. In addition,
In FIG. 1 and FIG. 2, when the horizontal drawing pipe extends from the toilet on the first floor and merges with the vertical drawing pipe 2, a normal piping configuration is used, and when only the toilet on the first floor is used. In
Orthogonal joints A may be interposed between the horizontal drawing pipe and the vertical drawing pipe. In the conventional configuration, the water trap of the drain trap and the sound of air entrainment at the time of drainage are generated, and the orthogonal joint A of the present invention has a collision plate on the front surface of the wall surface 5 in order to solve such a problem. 3 is erected.

The drainage pipe joint of a house according to the present invention is shown in FIGS.
It is configured as shown in FIG. That is, the orthogonal joint A forms an orthogonal portion where the horizontal drawing pipe 1 and the vertical drawing pipe 2 join. Both the horizontal drawing pipe 1 and the vertical drawing pipe 2 are cylindrical pipes, and the collision plate 3 shown in FIG. 4 is erected on the front surface of the wall 5 on the extension of the horizontal drawing pipe 1 of the orthogonal joint A. Things. The gist of the present invention is that the collision plate 3 is provided upright in front of the wall surface 5 so that a gap 7 can be provided between the collision plate 3 and the wall surface 5.

If the collision plate 3 is not provided on the front surface of the wall 5, when the drainage of the horizontal drawing pipe 1 flows into the vertical drawing pipe 2, the entire inside of the orthogonal joint A is filled with water. The overflow condition occurs. Due to this state of full flow, the inside of the drain pipe becomes negative pressure as the drain water descends, and the negative pressure causes the water in the trap 15 to be drawn out and cut off. If the seal is broken, it will cause the odor to return and also generate air entrainment noise.

In the present invention, the wall 5 in the orthogonal joint A
The collision plate 3 is arranged in front of the
Is formed, an air layer is formed in this portion, and the inside of the orthogonal joint A and the inside of the drainage pipe are always maintained near the atmospheric pressure, so that a full flow state does not occur. The absence of a full-flow condition eliminates the occurrence of water seal breakage and no air entrainment noise.

[0011]

As described above, the present invention has the following advantages. First, in a portion of the orthogonal joint A between the horizontal drawing tube 1 and the vertical drawing tube 2, a special shape of the collision plate 3 is fixed in front of the wall surface 5 so that the full drawing state of the vertical drawing tube 2 portion can be achieved. Can be prevented, and the occurrence of a negative pressure state that has occurred with the lowering of the drainage inside the vertical drawing pipe 2 can be prevented. As a result, the portion of the trap 15 that is communicated with the horizontal drawing pipe 1 and the vertical drawing pipe 2 It is possible to eliminate running out of water. Secondly, there is no need to provide a ventilation pipe space, so that the space in the room is not narrowed, and the water around the house can be easily constructed. Third
In addition, since there is no need to use a ventilation pipe, the cost can be reduced. Fourth, since it is no longer necessary to open the end of the ventilation pipe to the outside atmosphere, it is effective in improving the design of the building and preventing odor leakage.
