Vacuum cleaners |
摘要 |
A vacuum cleaner includes an electric motor which drives a suction fan to draw air and debris into the cleaner via an inlet. The air and debris pass along a passageway and creates a suction at a bleed way to draw air through the motor and out of a compartment. Air enters the compartment through vents (not shown) in a side of an outer housing. The arrangement enhances the cooling of the motor and uses air uncontaminated with debris.
