WATER PURIFYING APPARATUS HAVING CLEANING SYSTEM

A water purifying apparatus comprises: a filtering unit; a water tank unit for storing water having passed through the filtering unit; an extraction unit for selectively extracting the water stored in the water tank unit; and a cleaning system for sequentially controlling a cleaning process and a rinsing process of the water tank unit. Since cleaning and rinsing processes for the water purifying apparatus are automatically executed by a series of consecutive processes, the user may directly clean the water purifying apparatus if necessary without requiring a Codi's visit. Furthermore, the number of times that the Codi visits the users home for cleaning of the water purifying apparatus is reduced. This may allow the Codi to have an enhanced working efficiency, and to pay less effort to a cleaning process for the water purifying apparatus.
