Abstract
A vacuum-aided toilet comprises a toilet bowl, a deodorization pipeline, a flushing pipeline, a sensing switch (4) and a control device. A flushing port of the toilet bowl is communicated with the deodorization pipeline. The deodorization pipeline is communicated to a vacuum device. Inside the toilet bowl are provided a trap I (1.1), a trap II (1.2) and a draining port (1.3). The flushing pipeline being connected to the flushing port of the toilet bowl and the trap II (1.2), respectively. The sensing switch (4) is connected to a control device, which controls the deodorization pipeline and the flushing pipeline. An ejector (2.4) mounted on an air discharge pipeline (2.5) is directly driven by gas from an air outlet of a ventilating fan (2.2), so that vacuum is produced in a draining pipe. Thus the vacuum-aided toilet can save water and get rid of the odor.
