Abstract: 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.

Abstract: A vacuum cleaner includes a cleaner main body including a suction motor for generating a suction force; a suction unit that is in communication with the cleaner main body and sucks air and dust; and a battery that supplies power to the suction motor. The vacuum cleaner also includes a battery management system (BMS) that detects a status of the battery; and a controller that controls an operation of the suction motor. If a voltage of the battery detected by the BMS reaches a changeable reference voltage, the controller stops the suction motor.
