摘要： The present invention relates to a blower, the blower according to an embodiment of the present invention comprising: a lower case having a suction hole formed therein through which air is introduced; an upper case arranged on the upper side of the lower case and having a discharge hole formed therein through which air is discharged; and a fan arranged in the lower case and including a plurality of blades. Each of the plurality of blades includes a plurality of airfoils respectively extending along different camber lines from one another, and a leading edge of connecting the leading ends of the plurality of airfoils. Entrance angles formed by the respective camber lines of the plurality of airfoils and the rotation directions of the blades are different from one another. Thus, due to the curved shape of the leading edge and the design of a recessed notch, a flow separating from the leading edge is reduced, and thus, there is an advantage in that air volume performance is improved.

摘要： A blower according to an embodiment of the present disclosure includes: a case; a fan; and a diffuser disposed downstream of the fan and guiding air, discharged from the fan, toward the discharge ports, wherein the diffuser includes: an outer wall; an inner wall spaced apart inwardly from the outer wall so that an air passage is formed therebetween; and a plurality of vanes extending radially between the outer wall and the inner wall and dividing the air passage into a plurality of unit passages, wherein the outer wall and the inner wall are formed to have areas with different radial separation distances D between the outer wall and the inner wall, such that in an area of the air passage of the diffuser in which air is discharged to a portion having a high flow resistance in the blower, the radial separation distance D increases to widen the air passage S, thereby compensating for the asymmetry of the passage inside the blower, allowing a uniform volume of air to reach the entire area of the discharge ports, and improving the performance of the blower.

摘要： A blower of the present disclosure includes: a lower case having a suction port; an upper case which has a pair of towers that are spaced apart from each other and form a space through which a discharge air flows therebetween; and a blower fan which is disposed inside the lower case and discharges air to the upper case, wherein each of the pair of towers has a discharge port that is elongated in an up-down direction and disposed closer to a rear end of the tower than a front end, and has an air guide, which is disposed therein, that guides the air discharged by the blower fan to the discharge port, wherein the air guide is convex upward, has one end disposed near a middle between the front end and the rear end of the tower, and has the other end disposed near a middle of a vertical height of the discharge port, wherein the other end is disposed higher than the one end, so that the direction of air flow discharged from the fan can be smoothly switched to the discharge port side by only a single air guide, thereby minimizing the flow resistance inside the blower and greatly improving the economic efficiency and manufacturability of the blower.
