Water purifier

摘要

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 Qti at 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 Qti at the (N−1)th time.

1. A water purifier comprising:
a purified water supply part generating purified water and supplying the purified water to an outside of said water purifier a timer part; a purified water quantity measuring part measuring a quantity of the purified water supplied by the purified water supply part; and a control and calculation part, wherein the purified water supply part repeats starting and stopping supply of the purified water N times (where N is a natural number), the timer part measures a first period from when the supply of the purified water is stopped for an (N−1)th time up to when the supply of the purified water is started for an Nth time, when a quantity of the purified water, measured by the purified water quantity measuring part, for a period of time from when the supply of the purified water for the (N−1)th time is started up to when the supply of the purified water for the (N−1)th time is stopped is smaller than a first quantity which is an amount of water to be discarded during the supply of the purified water for the (N−1)th time, the control and calculation part sets a second quantity which is an amount of water to be discarded during the supply of the purified water for the Nth time based on the first period and a difference between the first quantity and the quantity of the purified water, measured by the purified water quantity measuring part, for the period of time from when the supply of the purified water for the (N−1)th time is started up to when the supply of the purified water for the (N−1)th time is stopped.
