A DIRECTLY DRAINING TYPE WATER PURIFIER

摘要

The present invention relates to a directly draining type water purifier, and more particularly, to a directly draining type water purifier which allows general customers to easily exchange a water-purifying filter so maintaining costs is reduced. The purifier according to the present invention includes: a main body having a water-purifying filter; a protecting door installed to be opened or closed at the main body to protect the water-purifying filter; an on-off valve for a raw water transferring passage (hereinafter referred to as a raw water valve) for opening or closing a raw water transferring passage connected to the water-purifying filter to introduce the raw water from the outside; an on-off valve for a residual pressure discharging passage (hereinafter referred to as a residual pressure valve) for opening or closing a residual pressure discharging passage connected to the water-purifying filter to discharge pressure to the outside; and a discharging part for discharging the water purified by the water-purifying filter. Further, when the protecting door is opened, the raw water valve is closed to cease a supply of the raw water to the water-purifying filter while the residual pressure valve is opened to discharge a residual pressure water of the water-purifying filter through the residual pressure discharging passage, and when the protecting door is closed, the raw water valve is opened and the residual pressure valve is closed.
