| 摘要 |
It is described herein an air-assisted hydrodynamic toilet cistern operating as a closed circuit vessel directly connected to the mains with high pressure water whose level comes up during filling, compresses the content of the spaces (26) above the level (24) by saving energy usable in the discharge stage during which, upon the switch-valve (5) opening, forced water is discharged through the opening (2) to clean up the toilet seat. The invented toilet cistern does not include the damage-sensitive flow-controlling attachments (floats, valves etc) of the previous state of art; it bears uniquely an opening for the water inlet and outlet connection (3,4) and the opening (4) for the replenishment of the upper space with air. |
