Publication number: 20120233805Abstract: A scroll assembly for use with a fluid machine, such as a wet/dry vacuum appliance, is described. Such scroll assembly may include a base portion, a cover portion configured to couple to the base portion, and a cavity between the base portion and the cover portion, wherein the cover portion and the base portion collectively form a labyrinth seal when coupled together, and wherein the labyrinth seal at least partially circumscribes the cavity. A vacuum appliance may include a scroll assembly coupled at least partially therein. A method of exhausting air from a vacuum appliance may include energizing a vacuum motor, thereby drawing air into the scroll assembly, allowing the air to contact a flow splitter, and allowing the air to exit the vacuum appliance.Type: ApplicationFiled: March 15, 2012Publication date: September 20, 2012Applicant: EMERSON ELECTRIC CO.Inventor: Matthew A.

Patent number: 8266763Abstract: A leaf and lawn vacuum bagger has a housing that is attached to the exhaust outlet of a conventional leaf and lawn blower/vacuum or mulching device, and an air permeable bag releasably connected to the exhaust outlet has a fastener closure at a bottom end. A flexible sleeve is secured at one end to the housing and the air permeable bag is releasably connected at the opposed end for capturing the vacuumed yard debris. A closure member attached to the housing is selectively closed to allow exhaust gases from the lawn blower/vacuum or mulcher device to exit through the pores of the air permeable bag to the atmosphere, and leaves and yard debris exhausted through the blower/vacuum or mulcher falls down through the interior of said air permeable bag, through said sleeve, and are collected in the housing interior, and when opened, the collected leaves and yard debris falls through the housing and into the attached disposable bag, and the attached bag is then removed and replaced as needed.Type: GrantFiled: August 2, 2011Date of Patent: September 18, 2012Inventor: John N.

Publication number: 20120227210Abstract: Disclosed is an exhaust air feedback robot cleaner equipped with a disinfectant anion generator, including a suction motor to intake not only air but also dust from a to-be-cleaned surface through a suction unit installed at the bottom surface and a dust collector to trap dust so as to allow dust-free air to be discharged via the suction motor. In the robot cleaner, the disinfectant anion generator emits disinfectant anions to disinfect the air having been discharged via the suction motor, a spray nozzle installed at the front end of an intake port of the robot cleaner sprays the disinfected air toward the cleaning surface through an exhaust air feedback unit so that the dust on the to-be-cleaned surface may be scattered and disinfected, and finally the air, together with the dust, is sucked in by the suction motor and circulated again to the exhaust air feedback unit.Type: ApplicationFiled: September 2, 2010Publication date: September 13, 2012Applicant: HANOOL ROBOTICS CORPORATIONInventors: Byung-Soo Kim, Byung-Soo Lee, Nam-Su Lee
