Abstract: Provided are a filter unit which may easily replace a filter, and a refrigerator including the same. To this end, a filter unit according to the present disclosure includes a filter which purifies water, a filter head which is disposed on one end portion of the filter, and includes an inlet port which supplies raw water to the filter and is formed to protrude from one side thereof, and an outlet port which discharges pure water purified by the filter and is formed to protrude from the other side thereof, a filter housing which is formed with a filter accommodation space in which the filter is accommodated, a filter bracket which is coupled to the filter housing, and includes an inlet port coupling part to which the inlet port is coupled rotatably, and an outlet portion coupling part to which the outlet port is coupled rotatably, and a filter door which is coupled to the filter housing to open and close the filter accommodation space.

Abstract: Proposed is a water purification filter assembly including a filter main body, an inlet port through which feed water is supplied from the outside and an outlet port through which the purified feed water is discharged being formed in the filter main body, a water purification tank arranged on one side of the filter main body, the feed water purified in the filter main body being stored in the water purification tank, a first casing, at least one side of the water purification tank being accommodated in the first casing obliquely at a predetermined angle with respect to the ground, and a second casing perpendicularly coupled to one end portion of the first casing, the filter main body being accommodated in the second casing.

Abstract: The present invention relates to a tube-fitting structure for a pure-water line of a water purifier or refrigerator. The present invention provides a tube connecting structure in which a tube fitted into a body having a fitting part formed therein is fixed by a cap, wherein a guide groove formed to have a receiving recess curved downward is formed on an outer circumferential surface of a tube link part of the body, and wherein a guide protrusion is formed on an inner circumferential surface of the tube corresponding to the outer circumferential surface of the body to allow the guide protrusion to be coupled along the guide groove, so that the tube is easily assembled with the body while the cap is rotated due to an inclined surface of the guide groove. Thus, in spite of enhancing the air tightness of the fitting structure, the assembly is improved.
