口径の管体で配管してもよい。In the present invention, an intermediate tank with an intake valve is provided between the water-sealed trap and the drainage stack or the negative pressure generator. That is, either the negative pressure generating device or the drainage stack pipe may be provided first, but an intermediate valve with an intake valve is provided between the negative pressure generating device or the drainage stack pipe and the water-sealed trap that are provided first. A tank is provided. And the piping from the drainage generator to the inlet of the intermediate tank is 1/100
The pipes are connected by a normal pipe body having the above-mentioned downward slope, but since the piping from the intermediate tank to the drainage stack pipe is pressure-fed by the pressure difference due to the negative pressure generator, it is necessary to make the downward slope at 1/100 or more. There may be no gradient, and there may be some unevenness. Further, a pipe having a smaller diameter than that of the conventional free-flowing type pipe may be used.

から好適である。Therefore, as the mounting position of the intermediate tank is closer to the water-sealed trap, the pipe having a downward slope of 1/100 or more becomes shorter. Such a short length is preferable because it does not occupy a piping space even if the slope is considerably steep and the construction is easy. The pipes used for the pipes used in the present invention can be the pipes used for the conventional pipes. For example, a steel pipe, a cast iron pipe, a concrete pipe, a synthetic resin pipe, etc. can be used. Particularly, in the present invention, a flexible pipe such as a polyethylene pipe, a cross-linked polyethylene pipe, a polypropylene pipe, a polybutene pipe, a soft polyvinyl chloride pipe or a soft synthetic resin pipe or a composite pipe of polyethylene resin, metal foil and polyethylene resin. However, it is preferable because the piping work and the exchange of the pipe body can be easily performed.

The caliber can be reduced. For example, the tubular body used for the horizontal drainage pipe from the intermediate tank to the vertical drainage pipe has conventionally been a tubular body having a diameter of 75 mm.
In the present invention, a pipe having a diameter of 40 mm may be used, and as the horizontal drain pipe connected to the washbasin, a pipe having a diameter of 40 mm has been conventionally used, but in the present invention, the diameter may be 20 mm.

は負圧にならない。The operation status of the drainage facility of the present invention will be described. In the drainage facility of the present invention, the negative pressure generator operates when the drainage is generated from the drainage generator. This negative pressure generator sucks the drainage and gas inside the pipe to create a negative pressure inside the pipe before the negative pressure generator such as a horizontal drain pipe, but the negative pressure generator and the water seal near the drainage generator are sealed. An intermediate tank with an intake valve is provided between the trap and the trap, and when the internal pressure of the pipe becomes negative, the intermediate tank connected to the pipe becomes negative, the intake valve opens, and air is discharged from here. Aspirate. Therefore, the inside of the pipe before the intermediate tank does not become negative pressure.

い。Therefore, the water-sealed trap located in front of the intermediate tank operates in a conventional manner regardless of the negative pressure generator. In the drainage equipment of the present invention, since water is forcibly sucked in by the negative pressure generator in the pipe after the intermediate tank, the pipe of this portion can use a pipe having a diameter smaller than that of the conventional one. There is no need to make a downward slope of 100 or more.

When drainage is generated in the bathtub 1c, this drainage flows into the intermediate tank 4 via the water-sealed traps 2a, 2b, 2c. Then, the water level sensor 13 provided in the intermediate tank 4 operates, the pump 15 operates, and the drainage in the pipe body 8 that has exited from the intermediate tank 4 is pressure-fed toward the drainage stack 9. At this time, as a result of the drainage in the pipe body 8 before the pump 15 being drawn into the pump, the pipe body 8 becomes a negative pressure and the intermediate tank 4 becomes a negative pressure,
Since the intermediate tank 4 is provided with the intake valve 7, air enters from there and the inside of the pipe body 3 does not become a negative pressure. Therefore, the water seal of the water seal traps 2a, 2b, 2c is not broken.
