VACUUM CLEANER HAVING HINGED INLET COVER
A vacuum cleaner basically includes a motor, first and second inlets and a cover. The motor is configured to create flow through a suction path. The first inlet and the second inlet are disposed in the housing in fluid communication with the suction path. A cover is pivotably disposed in the second inlet. The cover is movable between a first position in which the second inlet is substantially covered to substantially prevent fluid from flowing through the second inlet and a second position in which fluid is allowed to flow through the second inlet.
This invention generally relates to a vacuum cleaner. More specifically, the present invention relates to a vacuum cleaner having a hinged inlet cover.
Background InformationVacuum 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 free dirt particles 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.
Vacuum cleaners are provided with devices that agitate the carpet surface to dislodge ingrained dirt particles. For example, mechanical beaters physically strike the carpet surface to loosen dirt particles. Such agitators are often located on the vacuum cleaner nozzle head, so that dirt can be dislodged and instantly removed by moving the nozzle head across a soiled carpet surface. An example of a mechanical beater is a cylindrical rotatable beater brush having a plurality of extending resilient bristles and prongs that physically beat the carpet as the nozzle head is moved.
A recent trend in carpet manufacturing is soft carpets, which are made of softer yarns. Denier quantifies the softness of the yarn, and is the weight in grams of 9,000 meters of the yarn. The larger the denier, the thicker the yarn. Denier per filament (DPF) represents the size of an individual filament of the yarn. The lower the DPF, the softer the fiber. Traditional home carpets have a DPF of between approximately 12 to 18 DPF. The new soft carpet trend has resulted in carpets having a DPF between approximately 3.5 to 4.5 DPF. These soft yarns can have three to four times as many filaments as in the traditional home carpets. Traditional strands of yarn have approximately 120 filaments. The soft strands of yarn can have approximately 700 or more filaments.

Softer carpets have an increased surface area of the fibers, which increases the drag across a surface with the vacuum cleaner. Additionally, the increased surface area increases the difficulty of pulling air through the carpet, which slows down or stops the mechanical beaters, such as the brush roll 32, of the vacuum cleaner. Soft yarn strands also lack the stiffness of traditional carpets, such that vacuum cleaners tend to sink in the soft carpets. The soft yarn strands tend to form a more complete seal around the vacuum cleaner base, thereby increasing suction at the point of contact with the soft carpet surface. The more the vacuum cleaner base sinks into the soft carpet, the greater the suction and the difficulty of operating the vacuum cleaner. Being able to automatically adjust the airflow through the second inlet 48 allows a user to compensate for the issues raised with softer carpets, while also allowing the vacuum cleaner to automatically adjust to different types of carpeted surfaces.
