<p>A water purifier including a sediment filter (100), a pre-carbon filter (200) and a membrane filter (300) to sequentially filter raw water. An automatic flushing apparatus of the membrane filter (300) includes an LPS (120) for detecting water pressure in a water pipe connected between the sediment filter (100) and the pre-carbon filter, a pump (130) for pumping water fed from the sediment filter (100) to the pre-carbon filter (200), a controller (600) for enabling controlled flushing of the water from the inside of the membrane filter (300) from a time point where a pumping voltage is detected, and a flush regulating valve (310) for opening a flush pipe of the membrane filter (300). The water is flushed out from the inside of the membrane filter (300) through the flush regulating valve (310) while removing scales from the inside of the membrane filter (300) under flushing pressure thereof.</p> |
