The invention relates to a closestool. The closestool comprises a closestool body, wherein an S-shaped water absorption tube is arranged in the closestool body; a valve I is arranged at a position on the water absorption tube, on a path at the rear part of a water seal section; a valve II is arranged at a position on the water absorption tube, on a path behind the valve I; a closed space is formed between the valve I and the valve II; a vacuumizing device which can vacuumize the space is arranged on the space. According to the closestool disclosed by the invention, before objects are discharged, the closed space is formed by the valve I and the valve II firstly, and then, the closed space is vacuumized by the vacuumizing device; when objects need to be discharged, the valve I and the valve II are opened; due to pressure difference, water streams can drive the objects to easily exceed the peak of the water absorption tube under the effect of the air pressure, and syphonage is formed, so that the objects can be quickly discharged. The closestool disclosed by the invention can enable objects to be discharged with very small amount of water, and the closestool can be flushed clean, so that water consumption is greatly reduced.
