<p>According to an embodiment of the present invention, cooling efficiency is improved by cooling a cord reel and a circuit board using inhalation with a low temperature when compared to an exhaust of a vacuum cleaner, and a separately equipped flow path structure is simply realized to cool the cord reel and a circuit unit. According to an embodiment of the present invention, the vacuum cleaner comprises: a case equipped with a motor and a circuit unit; the cord reel wherein external air flows inside by an inhalation force of the motor; and a flow path guide guiding the flowing air to be discharged to a side of the circuit unit as the air having passed through the cord reel flows in.</p> |
