Abstract
A brush roller assembly for a vacuum cleaner includes a spindle rotatable within a vacuum cleaner housing. A first airflow enhancing device (AED) may be attached to the first end of the spindle. When rotated, the spindle may increase the flow of air from the end of the spindle toward the central portion of the spindle and thereby improve the vacuum cleaner's edge cleaning capability.
Claims29
A vacuum cleaner comprising:
- a housing having a top, a bottom and first and second side walls, an intake aperture is provided in the bottom of the housing, first and second openings are provided in the first and second side walls, respectively;
- a drive motor supported to the housing;
- and,
- a device comprising:
- (a) a spindle operatively connected to the drive motor and selectively rotatable within the housing, the spindle having a central portion and first and second ends juxtaposed to the first and second openings in the housing, respectively;
- (b) a first airflow enhancing device positioned on the first end of the spindle, the first airflow enhancing device is selectively rotatable by the spindle to increase the flow of air from the intake aperture and first opening to the central portion of the spindle;
- and,
- (c) a second airflow enhancing device positioned on the second end of the spindle, the second airflow enhancing device is selectively rotatable by the spindle to increase the flow of air from the intake aperture and second opening to the central portion of the spindle.
5 more elements
The vacuum cleaner of claim I wherein the spindle comprises:
- first and second recesses formed in the first and second ends of the spindle, respectively, wherein at least a portion of the first and second airflow enhancing devices are positioned within the first and second recesses, respectively.
A vacuum cleaner comprising:
- a housing having an intake aperture and a first opening;
- a drive motor;
- and,
- an assembly comprising:
- (a) a spindle operatively connected to the drive motor and selectively rotatable within the housing, the spindle having a central portion and a first end juxtaposed to the first opening in the housing;
- and,
- (b) a first airflow enhancing device positioned on the first end of the spindle, the first airflow enhancing device is selectively rotatable by the spindle to increase the flow of air from the intake aperture and first opening to the central portion of the spindle.
4 more elements
A device comprising:
- a spindle having first and second ends and a central portion, the spindle is adapted to be driven by a vacuum cleaner motor and rotated within a vacuum cleaner housing;
- and,
- first and second airflow enhancing devices fixed on the first and second ends, respectively, of the spindle, the first and second airflow enhancing devices are selectively rotatable by the spindle to increase the flow of air from the first and second ends of the spindle to the central portion of the spindle.
A method comprising the steps of:
- providing a vacuum cleaner comprising:
- (1) a housing having an intake aperture and a first opening;
- and, (2) a drive motor;
- providing a device comprising a spindle operatively connected to the drive motor and selectively rotatable within the housing, the spindle having a central portion and a first end juxtaposed to the first opening in the housing;
- and,
- operating the drive motor to rotate the spindle thereby drawing air through the first opening and along the longitudinal axis of the spindle from the first end toward the central portion.
