HISTORY AND PERSPECTIVES OF DEVELOPING THE TOILET DESIGN AND CONSTRUCTION
Research is devoted to the study of the history of toilets and its flushing and drain devices, and how the design of modern toilet bowl came down to us in its present form. The technical issues of toilet flushing system were described as a reason of water leaks, that modern inventions in sewer systems should prevent. New inventions in sanitary equipment are described, and the conclusion is that there are some ways how we can make this device more economic, to safe more water that we use. The tilt angle of drain tray, for example, can be increased to make the water flow faster, and, as a consequence, washing efficienty will be increased. Also the modern toilet is moving forward, and nowadays it can be used as a private laboratory to observe the human health. The research gives other directions for future development of the design of toilets, for reason to improve efficiency and economic performance.
