20130045084 | LOW-NOISE BLADELESS FAN - A low-noise bladeless fan includes a base, a nozzle at the top of the base and noise-reduction components located within the base. The noise-reduction components include a first noise-reduction component, a second noise-reduction component and a third noise-reduction component. The first noise-reduction component is located at an interface between air outlets and an internal passage for airflow reduces noise by isolating, obstructing and separating noise created inside the outer casing. The second noise-reduction component is disposed within an impeller fixture reduces noise by absorbing noise created inside the outer casing. Through-holes are disposed in the bottom of the outer casing act as the third noise-reduction component and also reduce noise. The arrangement of noise-reduction components can reduce noise created in the fan, thereby cooling users with natural and soft wind. | 02-21-2013 |
