The present dehumidifier comprises: a body having an intake opening and a discharge opening; a blowing fan arranged inside the body so as to draw air into the body through the intake opening and to discharge the same to the outside through the discharge opening; a fan case having a duct arranged inside the body so as to provide a channel through which the air drawn by the blowing fan flows to the discharge opening; a heat exchanger arranged inside the body so as to remove moisture from the air that has flown into the body; and fixed blades that are fixedly installed inside the duct so as to split the air, which has flowed through the channel, to a plurality of discharge paths. ## Claims ### Claim 1 A dehumidifier comprising: a body having an intake opening and a discharge opening; a blowing fan arranged inside the body and configured to draw air into the body through the intake opening and to discharge the air to an outside through the discharge opening; a fan case arranged inside the body and provided with a duct forming a channel through which the air drawn by the blowing fan flows to the discharge opening; a heat exchanger arranged inside the body and configured to remove moisture from the air that flows into the body; and fixed blades fixedly installed inside the duct and configured to split the air, which flows through the channel, to a plurality of discharge paths. ### Claim 2 (depends on 1) The dehumidifier of claim 1, wherein the fixed blades are arranged across a width direction of the discharge opening. ### Claim 3 (depends on 2) The dehumidifier of claim 2, wherein the fixed blades have preset heights toward the discharge opening and are arranged to be parallel with one another. ### Claim 4 (depends on 2) The dehumidifier of claim 2, wherein the discharge opening is provided in an upper part of the body, and upper ends and lower ends of the fixed blades are arranged to be off-center to one another. ### Claim 5 (depends on 4) The dehumidifier of claim 4, wherein the duct has a shape of which a cross-sectional area increases upwards and has a first slope part having a shape sloping upwards to the discharge opening and a second slope part that is arranged opposite to the first slope part has a gentler slope than the first slope part, and wherein the fixed blades respectively have front fixed sides that are arranged to face the first slope part and have first curvatures that are convex toward the first slope part and rear fixed sides that are arranged to face the second slope part and have second curvatures that are concave toward the second slope part. ### Claim 6 (depends on 1) The dehumidifier of claim 1, further comprising: a dispersion plate that is arranged on sides of the fixed blades inside the duct and has a plurality of dispersion holes through which air flowing through the fixed blades is dispersed. ### Claim 7 (depends on 6) The dehumidifier of claim 6, wherein the dispersion holes are hexagonal shapes, and the dispersion plate is formed in a honeycomb structure. ### Claim 8 (depends on 1) The dehumidifier of claim 1, further comprising: a rotating blade that is arranged on sides of the fixed blades and configured to change a discharge direction of air that flows through the fixed blades. ### Claim 9 (depends on 8) The dehumidifier of claim 8, wherein the discharge opening is formed in an upper side of the body, and the rotating blade is arranged across the width direction of the discharge opening. ### Claim 10 (depends on 9) The dehumidifier of claim 9, wherein the rotating blade includes a plurality of rotating blades, and the rotating blades have preset heights along upward and downward direction and are arranged to be parallel with one another. ### Claim 11 (depends on 9) The dehumidifier of claim 9, wherein the fixed blades are arranged at preset distances along a longitudinal direction of the discharge opening and have the preset heights along the upward and downward direction, and wherein a number of rotating blades is equal to or smaller than a number of the fixed blades. ### Claim 12 (depends on 9) The dehumidifier of claim 9, further comprising: rotation axes that are respectively axially combined with the rotating blades and are rotatably supported by the duct; a driving member that is connected to at least one of the rotation axes and rotates the rotation axis; and a link member that is arranged under the rotation axes and connected to the rotating blades. ### Claim 13 (depends on 12) The dehumidifier of claim 12, wherein the rotating blades are arranged under the rotation axes and have projections projecting from the rotating blades, and wherein the link member is arranged perpendicular to the rotating blades and has fixing holes into which the projections are inserted and rotatably supporting the projections. ### Claim 14 (depends on 12) The dehumidifier of claim 12, wherein the rotating blades rotate in one direction by a driving force of the driving member to position in a first position where the upper ends of the rotating blades are off-center to sides of the lower ends, and rotate in an opposite direction to switch to a second position where the upper ends of the rotating blades are off-center to other sides of the lower ends. ### Claim 15 A dehumidifier comprising: a body having an intake opening and a discharge opening; a blowing fan arranged inside the body and configured to draw air into the body through the intake opening and to discharge the air to an outside through the discharge opening; a fan case arranged inside the body and provided with a duct forming a channel through which the air drawn by the blowing fan flows to the discharge opening; a heat exchanger arranged inside the body and configured to remove moisture from the air that flows into the body; fixed blades fixedly installed inside the duct and configured to split the air, which flows through the channel, to a plurality of discharge paths; rotating blades arranged above the fixed blades and configured to change a discharge direction of air that flows through the fixed blades; and a dispersion plate arranged between the fixed blades and the rotating blades and having a plurality of dispersion holes through which the air split by the fixed blades is dispersed.
