Flush Toilet (1596)

Various versions of flushing toilets were used as far back as the 26th century BC in the Indus Valley, where the cities of Harappa and Mohenjo-daro had a flush toilet in almost every house, attached to a sophisticated sewage system. The true prelude to the modern flush toilet began in 1596 when Sir John Harington installed his version of a flush system for the Queen of England.

沖水馬桶（1596年）

人們早在公元前26世紀就開始使用各種形態(tài)的沖水馬桶了，當時在印度河流域的哈拉帕市和摩亨佐-達羅，幾乎每所房子里都有一個抽水馬桶，馬桶和精密的下水道系統(tǒng)相連接。現代抽水馬桶真正拉開序幕是在1596年，當時約翰?哈靈頓爵士為英國女王安裝了一個自己設計的沖水馬桶系統(tǒng)。
