Definitions

  • the present invention relates to but is not limited to the sanitary ware field, and in particular to but is not limited to a toilet device, a flushing system and a flushing method thereof.
  • Flush toilets are a major contributor to a clean and healthy environment, but a major drawback of flush toilets is their long-term water consumption. In the context of limited water resources and water supply disruptions caused by droughts or floods, better water conservation capabilities of flush toilets are urgently needed.
  • the volume of water required to flush a toilet for solids and liquids is usually about 6 litres per flush.
  • two different flush volumes are used to flush the toilet, one for solids and faeces (full flush) and one for the flush after the user urinates, i.e. a half flush (or economy flush). This means that when a user urinates in the toilet, 3 litres of water are removed with each flush. Flushing toilets is expensive, both because the wastewater after flushing needs to be treated and because of the investment in sewer infrastructure, which has operating and maintenance costs that make cleaning the sewers expensive.
  • one flushing technology is used in vacuum toilets, such as those used in transportation systems such as trains and airplanes.
