Patent ID: 8622084

Claim:
A liquid-suctioning tank comprising: a first liquid inflow port and a second liquid inflow port communicating with an upper space of a surface of a liquid when the liquid is stored in the liquid-suctioning tank, the first liquid inflow port and the second liquid inflow port being configured and arranged to be connected to a liquid-suctioning object, the first liquid inflow port and the second liquid inflow port being opened in a ceiling of the liquid-suctioning tank; a gas outflow port communicating with the upper space, and configured and arranged to be connected to a suctioning device so that a negative pressure is applied to the upper space by the suctioning device to trap liquid from the liquid-suctioning object using suction; a first baffle plate and a second baffle plate suspended from the ceiling of the liquid-suctioning tank and disposed in the upper space so that the liquid flowing from the first liquid inflow port collides against the first baffle plate and the liquid flowing from the second liquid inflow port collides against the second baffle plate; a support rod suspending the first baffle plate and the second baffle plate on the ceiling of the liquid-suctioning tank; and a guide member having a guiding wall configured and arranged to guide the liquid that has collided with the first baffle plate or the second baffle plate from the first baffle plate and the second baffle plate toward the surface of the liquid, the guiding wall is disposed between the first liquid inflow port and the second liquid inflow port, and between the first baffle plate and the second baffle plate.
