This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Application Ser. No. 61/775,268, filed Mar. 8, 2013, which is hereby incorporated by reference in its entirety.
FIELD OF THE INVENTIONThe present invention relates to a brushless vacuum cleaner having a vibrating member to facilitate removing dirt and debris from a surface to be cleaned. More particularly, the present invention relates to a brushless vacuum cleaner having a vibrating member vibrated by air drawn into a vacuum head. Still more particularly, the present invention relates to a brushless vacuum cleaner having an impeller for vibrating a vibrating member in which the impeller is driven by air passing therethrough.
BACKGROUND OF THE INVENTIONConventional vacuum cleaners typically use a suction nozzle that is movable across a surface to be cleaned. The suction created at an inlet in the nozzle results in the removal of dirt and debris accumulated on the surface. However, ground-in dirt is frequently encountered when cleaning carpets or other textured surfaces, and reliance on suction for removal of such ground-in dirt has proven to be unsatisfactory.
Accordingly, effort has been made to provide vacuum cleaners with an effective means to agitate the carpet surface to dislodge ingrained dirt and debris. Such beaters are often located on the vacuum cleaner nozzle head, so that dirt can be dislodged and instantly removed by simply moving the nozzle head across a soiled carpet surface. The earliest known beaters are mechanical beaters, which physically strike the carpet surface to loosen dirt particles.
One example of a mechanical beater is a brush roll that agitates a surface to be cleaned to loosen dirt and debris therefrom that might not be removed from the surface by the suction force of the vacuum cleaner. The brush roll is driven by a motor disposed in the vacuum cleaner. The brush roll typically has a substantially cylindrical shape with a plurality of outwardly extending bristles. The motor rotates the brush roll such that the surface to be cleaned is agitated by the bristles moving over the surface.
However, the brush roll can cause wear of the surfaces being cleaned over time and can result in premature replacement thereof. Additionally, the brush roll also wears down over time, thereby requiring replacement.
Conventional brushless vacuum cleaners do not have a brush roll or the motor for driving the brush roll. The conventional brushless vacuum cleaners are lighter and do not wear down surfaces as vacuum cleaners having brush rolls. Accordingly, a need exists for a brushless vacuum cleaner having a vibrating member to facilitate removing dirt and debris from the surface being cleaned.
SUMMARY OF THE INVENTIONA brushless vacuum cleaner in accordance with exemplary embodiments of the present invention provides a vibrating member disposed in a vacuum cleaner head to facilitate removing dirt and debris from a surface to be cleaned. Dirt and debris loosened by the vibrating member can be lifted from the surface being cleaned by a suction inlet disposed in the vacuum head of the brushless vacuum cleaner, thereby increasing the efficiency of the brushless vacuum cleaner.
The brushless vacuum cleaner can have a suction inlet disposed in the vacuum cleaner head in any suitable position, such as, but not limited to, in the vibrating member, in the vibrating member, in front of the vibrating member, behind the vibrating member, or in front of and behind the vibrating member.
