Provided is a water purifier comprising: a filter unit filtering water supplied from a water source, including a reverse osmosis filter; a discharge unit discharging water filtered by the filter unit externally; a flushing portion connected to the reverse osmosis filter; and a controller configured to flow water filtered by the reverse osmosis filter to the flushing portion, and to flush the reverse osmosis filter.

Water purifier and control method for water purifier

According to one embodiment of the present invention, a control method for a water purifier comprises the steps of: filtering inflowing water so as to generate purified water; extracting the generated purified water; measuring the flow rate of the purified water extracted per unit time; flushing a filter part by using purified water generated in the filter part, when the extraction of the purified water is complete; and draining the flushed water to the outside through a residential water outlet of the filter part, wherein, in the purified water generation step, discharging of residential water generated in the purified water generation step is blocked according to the accumulated flow rate during a one-time extraction of the purified water, calculated on the basis of the flow rate of the purified water.

A reverse osmosis filtering module includes: a purified water discharge pipe in which a purified water discharge path is formed, and which has a communication hole that is formed on an outer periphery thereof and communicates with the purified water discharge path; a reverse osmosis filtering part including a reverse osmosis filtering member in which a purified water flow space is formed, and which is wound around the purified water discharge pipe such that the purified water flow space communicates with the communication hole; a first flow channel formation cap provided at one side and having an inlet hole; and a second flow channel formation cap provided at the other side of the reverse osmosis filtering part and having an outlet hole.

Reverse osmosis filtering module and reverse osmosis filter comprising same

A water purifier comprising: a filter unit comprising at least one filter filtering water to generate purified water; a flow rate sensor measuring a flow rate of the water; a concentrated water channel discharging concentrated water, having been filtered by the filter unit; an extraction unit extracting the purified water; a flow rate control valve controlling a flow rate of purified water; an opening and closing degree measurement unit, measuring a degree of opening and closing of the flow rate control valve; a concentrated water ratio calculation unit, calculating a ratio between purified water and concentrated water, according to the degree of opening and closing of the flow rate control valve; and a controller, using the flow rate of water and the calculated ratio between purified water and concentrated water, to calculate amounts of water used, integrating the calculated amounts of water, and calculating a lifespan (remaining life) of the filter.

Water purifier

Disclosed are a sterilizing structure of a water outlet and a water treatment apparatus including the same. The sterilizing structure of the water outlet according to an embodiment of the present invention may comprise a water outlet for discharging treated water treated in a water treatment device externally, and a sterilizer for sterilizing the water outlet.

Sterilization structure of water outlet and water treatment device containing same

The present invention provides a water treatment device comprising: a filtering unit for filtering raw water; a storing unit comprising a first chamber for storing purified water, which has passed through at least a predetermined number of filters provided in the filtering unit and thus has been filtered, and a second chamber, the volume of which changes according to the volume change of the first chamber; an extraction unit installed to provide the user with the purified water that has been filtered; an sterilizing water supply unit for supplying sterilizing water in order to sterilize/disinfect the storing unit; and a control unit for controlling the driving of the sterilizing water supply unit and the opening/closing of a channel for supplying the sterilizing water.

Water treatment device

Disclosed is a water treatment apparatus that includes a head including an inlet portion into which water flows, an outlet portion from which water is discharged externally, and a connection portion connected to the inlet portion and the outlet portion, and a water treatment unit connected to the connection portion, including a plurality of water treatment sections, coupled to the head, and configured such that a portion of the water flowing into the inlet portion passes through the plurality of water treatment sections and sequentially, the remainder of the water passes through only a portion of the plurality of water treatment sections and, and the water flows to the outlet portion together.
