<p>A reverse osmosis filter according to the present invention comprises: a flow path pipe (20) installed in the shape of a pipe to connect a water inlet (11) and a water outlet (12) of a filter case (10), having an inner partition (22) installed to be divided into the side of the water inlet (11) and the side of the water outlet (12), having a plurality of water discharge holes (23) on a side wall at the side of the water outlet (12) with respect to the inner partition (22), and having water inflow holes (21) on a side wall at the side of the water inlet (11); a reverse osmosis filter layer (30) including parts with the water discharge holes (23) and not including the water inflow holes (21) to make both ends of the flow path pipe (20) protrude laterally, thereby enveloping the side wall of the flow path pipe (20) in predetermined thickness (t); a blocking ring (40) installed between the reverse osmosis filter layer (30) and the filter case (10) to discriminate the side of the water inlet (11) from the side of the water outlet (12); a wastewater hole (13) installed on the filter case (10) to be placed at the side of the water outlet (12) with respect to the blocking ring (40); and an alkali member (50) installed on the inside of the flow path pipe (20) placed between the inner partition (22) and the water outlet (12), in a space between the flow path pipe (20) and the water outlet (12), on the reverse osmosis filter layer (30) or between the reverse osmosis filter layer (30) and the flow path pipe (20) to envelop the flow path pipe (20). According to the present invention, the acidification of water and the absence of minerals, which are the shortcomings of a reverse osmosis filter, are prevented by alkali particles, and alkali water containing various minerals can be obtained.</p> |
