Document Type and Number:
WIPO Patent Application WO/2010/045880
Kind Code:
A1
Abstract:
A suction pressure water closet includes an air communication duct (308, 408, 508, 608, 708, 808), whose one end is connected with the upper portion of a tank (301, 401, 501, 701) and the other end is connected with a pipeline of a drain pipe ( 203, 303, 503, 603, 703, 803) and the tank ( 301, 401, 501, 701) is communicated with the drain pipe ( 203, 303, 503, 603, 703, 803) by the air communication duct (308, 408, 508, 608, 708, 808). The water closet can make the pressure of the flushing water current more bigger and make the air pressure in the drain pipe more smaller to accelerate the velocity of flow, accordingly, the better flushing effect is achieved.
