A DIRECTLY DRAINING TYPE WATER PURIFIER WITH DUPLEX FILTER REPLACEMENT MODE

摘要

Provided is a directly draining type water purifier with a duplex filter replacement mode which is capable of minimizing inconvenience of a customer by automatically performing operations of blocking a source water supply and draining residual water only through an operation required to replace a filter such as an operation of pulling a purifying filter to exchange the purifying filter or open a protective door. The directly draining type water purifier includes a protective door installed to a purifier body having a plurality of purifying filters to be opened or closed to protect the purifying filters; a source water valve for opening or closing a source water passage through which source water introduced into the purifying filters passes; a residual pressure valve connected to at least one of the purifying filters to open or close a residual pressure outlet through which residual water passes; a first operation sensor for sensing a first operation of a user for exchanging a purifying filter; and a second operation sensor for sensing a second operation of the user which is possible to occur after the first operation is performed. The source water valve is controlled in response to the first operation and the residual pressure valve is controlled in response to the second operation.
