Abstract
A portable air cleaner designed to remove particles and unwanted gases from a room to provide for a healthier and cleaner environment. The portable air cleaner includes a high air volume circulating design and operates quietly and efficiently. The air exhaust of the air cleaner includes a plurality of arcuate vanes radiating outwardly from the interior of the air cleaner. The vanes are disposed in a non-symmetrical arrangement the air exhaust to reduce pressure drop and to minimize operation noise.
Claims79
A portable air cleaner that generates less vibrational noise during operation comprising a housing having an outer peripheral edge and an inner chamber, an air intake, air exhaust that provides a passageway for the expulsion of air from said inner chamber, a blower having a blade to draw air into said inner chamber through said air intake and to expel air from said inner chamber through said air exhaust, a filter disposed between said air intake and air exhaust to at least partially filter air drawn through said air intake, the improvement comprising said air exhaust having a plurality of arcuate vanes radiating outwardly from said blower, at least a portion of two of said arcuate vanes positioned non-symmetrically relative to said blade, said at least two of said arcuate vanes directing said air from said blade in a substantially unobstructed manner to said outer peripheral edge of said housing.
An air exhaust arrangement for a blower that generates less vibrational noise during operation comprising an outer peripheral edge, a blower, a blade rotatably connected to said blower, and a blower exhaust housing having an air passageway for the expulsion of air from said blower to the outer peripheral edge, said blower exhaust housing including a plurality of arcuate vanes radiating outwardly from said blade, each of said vanes having a length and two ends, each of said vanes having a radius of curvature over at least a section of said length of said vane, said first end of said vane positioned closer to said blade than said second end of said vane, said arcuate vanes directing said air in a substantially unobstructed manner to said outer peripheral edge, said second end of at least one vane extending to said outer peripheral edge of said housing, said arcuate vanes are positioned about said blade to reduce the amount of noise below about 20 KHz.
An air exhaust arrangement for a blower that generates less vibrational noise during operation comprising an outer peripheral edge, a blower, a blade rotatably connected to said blower, and a blower exhaust housing having an air passageway for the expulsion of air from said blower to said outer peripheral edge, said blower exhaust housing including a plurality of arcuate vanes radiating outwardly from said blade, each of said vanes having a length and two ends, each of said vanes having a radius of curvature over at least a section of said length of said vane, said first end of said vane positioned closer to said blade than said second end of said vane, said arcuate vanes directing said air in a substantially unobstructed manner to said outer peripheral edge, a plurality of said arcuate vanes being positioned about said blade non-symmetrically relative to said blade.
