[0003]

Drainage by the conventional natural flow-down method has the following problems, which causes complaints from residents and is a constraint condition at the design and construction stages.

(1) In the case of the second floor and above, since a water gradient is required for the horizontal pipes up to the vertical pipes outside the building, a large space, that is, a height, is provided between the floor surface of the room and the ceiling of the downstairs room. It is necessary and the total height of the building is high. (2) Skill level is required for piping work. That is, if the water gradient is not constructed properly, drainage failure will occur. In addition, the shape of the mounting portion of the vertical and horizontal drainage pipes may break the water seal in the drainage portion of the living room, causing odor and noise. (3) Therefore, in order to reduce the space between the floor surface and the downstairs ceiling, it is necessary to bring vertical pipes and water facilities such as kitchens, baths, and toilets close to each other, and to combine water facilities in one place. I can't do a free layout. As a result, when renewing, it is not possible to change the position of the facilities around the water drastically, so there are restrictions on the change of floor plan.

It is an object of the present invention to provide a mechanical drainage method for a building, which eliminates the constraint due to the water gradient in the piping.
