Abstract

A water purifier determining an appropriate discarded water quantity includes: a purified water supply; an integrated flow quantity measuring part; and a control and calculation part. The control and calculation part is configured to determine whether purified water is unsuitable for use based upon the integrated flow quantity measured for a period of time from when the supply is started. A value of water quantity Qat the Nth time is determined based on a length of time from when the purified water supply stops the supply at the (N−1)th time up to when the purified water supply starts the supply at the the Nth time; and a difference between a quantity of water measured for a period of time from when the supply at the (N−1)th time is started to when the supply at the (N−1)th time is stopped and a value of Qat the (N−1)th time.
