Patent number: 7591043Abstract: When the electrically driven fan (14) of a vacuum cleaner is driven, air containing dust is drawn into the cleaner main body (1) through a hose (7) connected to a hose socket (8) and is exhausted into the outside of the cleaner main body (1) through an exhaust port (1b) via first and second suction passageways (10, 13). Disposed outside the first suction passageway (10) is an ion generator (23), it being arranged that plus and minus ions generated in the ion generator (23) are fed to the air stream flowing in the first suction passageway (10). Since the plus and minus ions kill floating germs in the air stream, the exhaust can be purified.Type: GrantFiled: September 2, 2002Date of Patent: September 22, 2009Assignee: Sharp Kabushiki KaishaInventors: Kohji Ninomiya, Mikio Yagi, Shigenori Hato, Kazumasa Hayashi, Hiroshi Yoshimura, Yoshihiro Shimizu, Hideo Nojima, Hisaharu Yagi, Kazuo Nishikawa, Tetsuyuki Ohtani

Publication number: 20090158537Abstract: This static electricity and dust removing apparatus has a base box (11) provided with an airflow inlet port (16), and a processing head (23) attached to the base box (11) through a support column (21), wherein a processing space (24) is formed between the airflow inlet port (16) and the processing head (23). Air curtains for isolating the processing space (24) from the outside due to air from a spout of an air spout pipe (33) are formed at a front opening portion (29) and right and left side opening portions (28) of the apparatus. Ionized air generated by an ion generator (42) is spouted into the processing space (24), so that the ionized air is sprayed on matters to be processed which are disposed in the processing space (24) and dust is removed from the matters to be processed.Type: ApplicationFiled: June 15, 2005Publication date: June 25, 2009Inventors: Takahiro Ishijima, Jun Inomata, Shigeru Ohkawa

Patent number: 7299518Abstract: A cleaning head for a vacuum sweeper that incorporates a magnetic flux generator that bathes the area of carpet being engaged by the rotating brush beater in the cleaning head with a pulsing magnetic field. The magnetic flux generator disrupts the static attraction between opposing charged small particles and the carpet fibers to which the small particles are attached to allow the brush beater apparatus in the cleaning head to separate the small particles from the carpet fibers. The dislodged small particles, including allergens, bacteria and mold spores, are removed from the carpet in the air stream created by the vacuum sweeper and captured by a micro-filter filtration system. The magnetic flux field is created with the conventional household current that powers the operation of the vacuum cleaner without requiring the generation of high voltages or an electrostatic discharge from the cleaning head.Type: GrantFiled: November 20, 2003Date of Patent: November 27, 2007Inventor: Jerome I. Paulson
