Jet bottom-flushing method of water closet and water-saving trap water closet
The invention relates to a jet bottom-flushing method of a water closet and a water-saving trap water close. In order to solve the problem of high water consumption in flushing and drainage, at least one Laval throat pipe that a water injection nozzle thereof is immersed in the water seal of a trap under a normal state is made at or arranged at the water injection nozzle of a bottom-flushing water path, so that the air inlet nozzle of the water seal is exposed to suck air when the water seal fluctuates in the process of flushing and drainage. The water closet comprises a water closet main body, at least one trap water seal and a flushing water path which is arranged around the upper part of the water closet main body; a bottom-flushing water path that a water injection nozzle points to a blow-down pipeline stretches in the trap water seal; the lower end of the blow-down pipe is communicated with a sewer or a pit latrine; the water closet main body is communicated with a water supply pipeline by virtue of a gas-water pressure storage device and a pipe valve thereof; and at least one Laval throat pipe that a water injection nozzle thereof is immersed in the water seal under a normal state is made at or arranged at the water injection nozzle of the bottom-flushing water path, so that the air inlet nozzle of the water seal is exposed to suck air when the water seal fluctuates in the process of flushing and drainage. The water closet has advantages of high air intake amount and significant water-saving effect, and the water closet is free from problem of water leakage.
