VACUUM CLEANER (VARIANT) Russian patent published in 2008 - IPC A47L9/00 A47L9/22 

FIELD: items for personal and household use.

SUBSTANCE: inside the body of the vacuum cleaner there is a compartment for the motor, meant for mounting the motor unit, which creates a sucking force in the gap for sucking dust. In the body there is an exhaust window for directing air expelled from the motor compartment out of the vacuum cleaner. The motor compartment contains vents for the release of air, flowingly connected with the exhaust window, which is located in the first section of the body of the vacuum cleaner with vents for sucking air, joined with the vents for sucking dust, the second section with vents for air, located on the body of the vacuum cleaner between the first compartment and the exhaust window. Between the motor unit and the vents for the release of air is located an element extending the trajectory, which is the third compartment, placed in alignment with the vents for the release of air, connected with the first supporting element, which passes from the second partition, and at a distance from the second compartment, thereby forming a passage between the second and third compartments. The edges of the element extending the trajectory are at a space from the inner walls of the motor compartment, thereby forming a bypass. Air, expelled from the motor unit, is directed by the element extending the trajectory in such a manner, that it passes through the bypass before it reaches the exhaust vents. In this variant of a vacuum cleaner the first partition is located at the end of the body of the vacuum cleaner, and the third partition is placed in alignment with the exhaust vents, joined with the first supporting element, which passes from the second partition, and at a distance from the second partition, thereby forming a passage between the second and third partition. The distance between the inner walls of the motor compartment and the corresponding edges of the third partition is less than the distance between the inner walls of the motor compartment and exhaust vents.

EFFECT: effective reduction of working noise from the vacuum cleaner to the surrounding areas.
