Field of the Invention The present invention relates to a pipe joint having a vent used for piping of a drainage pipe of a building, and more particularly, to a pipe joint provided in a building having two or more stories . The present invention relates to a drainage pipe connected to a drainage facility having a trap such as a toilet bowl or a washbasin. 2. Description of the Related Art Conventionally, when a drain pipe connected to a drainage facility such as a toilet installed in a building of two or more floors is plumbed, a trap is generally employed in order to effectively maintain the water tightness of the trap. When the pipe is full at the junction of the vertical drainage pipe and the drainage pipe connected to the drainage equipment from the horizontal direction, the horizontal drainage pipe merges with the vertical drainage pipe on the upstream side. Air is sucked, and there is a problem that sealing water in a water distribution pipeline such as a toilet trap is discharged. Therefore, a method of connecting a ventilation pipe to a pipe downstream of a drainage facility such as a toilet with a pipe joint (cheese pipe) has been adopted. In this method, as shown in FIG. 3, a horizontal drain pipe 4 laid substantially horizontally is connected to an outlet 2 of a trap connected to a toilet bowl 1 via an elbow 3. A structure is adopted in which a cheese tube 5 is connected to an intermediate portion of the cheese tube 5 and a ventilation tube 6 is connected to the cheese tube 5. In the structure shown in FIG. 3, the end of the drain pipe 4 is connected to the vertical drain pipe, and even if a full state occurs at the junction of the vertical drain pipe and the horizontal drain pipe 4. Cheese tube 5
The air is sucked from the ventilation pipe 6 connected to the toilet and the trapped water in the toilet bowl 1 does not flow out. [0005] The structure shown in FIG. 3 requires a pipe joint such as a cheese pipe. I have. Therefore, in order to reduce the amount of piping material such as a cheese tube, as shown in FIG. 4, a structure in which a ventilation port 8 is formed in a horizontal direction on the upper outside of an elbow 7 connected to a drain port of a drainage facility. As shown in FIG. 5, a structure was conceived in which a ventilation port 10 was formed upward at the lower portion inside the elbow 9. However, in the elbow 7 having the structure shown in FIG. 4, dirt is liable to accumulate on the joint between the outer peripheral surface of the elbow 7 and the inner peripheral surface of the vent 8 projecting in the lateral direction. Further, in the elbow 9 having the structure shown in FIG. 5, there is a problem that dirt is easily scattered and adhered to the joint between the inner peripheral surface inside the elbow 9 and the inner peripheral surface of the ventilation port 10 protruding in the vertical direction. was there. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and reduces the number of piping members to improve piping workability. It is another object of the present invention to provide a pipe joint with a vent that does not allow water from a trap of a toilet or the like to flow out. A pipe joint with a vent according to the present invention has a large opening having an inlet opening upward at the upper end and an outlet opening substantially horizontally at the lower end. A curved elbow body, the center of the outlet of said elbow body
This elbow body whose extension is perpendicular to the center extension of the inlet
Passing from the outside substantially in eccentric part at an inclination of headed 45 ° obliquely upward of
It has an open vent connected to the trachea . According to the pipe joint with a vent of the present invention, the drainage side of a drainage facility such as a toilet is connected to the upper end inlet, and a substantially horizontal drainage pipe is connected to the outlet. When the pipe is fully filled at the junction with the connected vertical drain pipe, the air pipe connected to the ventilation port opened diagonally above the outside of the large elbow that is piped near the downstream of the drainage equipment It is ventilated from the trachea and the trapped water in the drainage system does not leak out. In addition, it is not necessary to provide a joint such as a cheese pipe for connecting the ventilation pipe in the drain pipe, and the construction can be easily performed. [0010] Furthermore, no dirt is accumulated or scattered in the ventilation hole in the elbow body, and the maintenance is easy. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of one embodiment of a pipe joint with a vent according to the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 11 denotes an elbow body which is curved in a substantially 90 ° direction.
A receiving tubular outlet 13 having an opening 12 is formed opening upward, and a receiving tubular outlet 15 having a step 14 having an enlarged diameter at the lower end has the same diameter as the inlet 13. In addition, the opening is formed in the horizontal direction. And this outlet
A tubular ventilation port 17 through which air can flow upward at an inclination of 45 ° upward from a substantially central portion outside the elbow body 11 in which a center extension line 15 and a center extension line of the inflow port 13 are orthogonal to each other, is the elbow body. It is formed integrally on the outside of 11. At the tip of the ventilation port 17, a reception step 18 is provided.
Is formed with an enlarged diameter. The diameter of the vent 17 is smaller than the diameter of the inlet 13 and the outlet 15. Next, the operation of this embodiment will be described. As shown in FIG. 2, the upper end inlet 13 of the elbow body 11 is connected to a drain outlet 21 of a trap (not shown) of a drainage unit 20 such as a toilet on each floor, and a drain 22 connected to a lower end outlet 15. Connect the horizontal drain pipe 22 to the vertical drain pipe
23 is connected to elbow 24, cheese tube 25 and the like. A vertical ventilation pipe 26 is connected to the ventilation port 17 of the elbow body 11 by using appropriate joints 27 and 28. Then, the sewage discharged from the drainage device 20 reaches a junction of the horizontal drainage pipe 22 and the vertical drainage pipe,
Even if the junction becomes full and air is sucked in from the drainage equipment 20 side, air flows in from the vent 17 and the inside of the drainage pipe 22 is not depressurized, so that the trapped water in the drainage equipment 20 flows out. I will not let you. And the air can be sucked from the ventilation pipe 26 by the elbow body 11 connecting the drainage equipment 20 and the drainage pipe 22,
A joint for sucking air can be omitted, and further, there is no possibility that dirt accumulates in the vent hole 17 of the elbow body 11 or is scattered and adheres. Also, piping work is facilitated. According to the present invention, since the ventilation port which opens obliquely upward is formed integrally with the outer central part of the elbow body, dirt flowing in from the inflow port can be removed by the ventilation part of the elbow body. It does not accumulate on or adhere to the drainage area, reliably prevents water from leaking out of the drainage system, eliminates the need for pipe joints for ventilation, reduces the number of piping members, and facilitates and maintains piping installation. Management becomes easier.
