| 20100017997 | Vacuum Cleaner - The invention relates to a vacuum cleaner of a type comprising an elongated support body ( | 01-28-2010 |
| 20100024154 | Vacuum Cleaner With Filter Cleaning Means - A hand held vacuum cleaner comprises a housing ( | 02-04-2010 |
| 20100083459 | Air Flow Losses in Vacuum Cleaners - A vacuum cleaner having an elongated support body, a nozzle attached to a lower end of the elongated support body by an articulated joint, a motor, a fan unit, a debris container, and an air passage that extends from the nozzle device, past the articulated joint by a flexible hose and to an air passage in the support body. The flexible hose is formed with a generally rectangular cross section. | 04-08-2010 |
| 20100242209 | Handheld Vacuum Unit Retention Features - A vacuum cleaner having a base with an inlet facing a surface, a handle connected to the base, an air passage connecting the base inlet to the handle, and a removable handheld unit. The handheld has an inlet nozzle, a dirt separator, a vacuum fan to generate a working airflow into the inlet nozzle and through the dirt separator, and a housing joining the handheld, the dirt separator and the vacuum fan. The vacuum has a docking latch with a first latch position in which the latch holds the handheld in an operating position on the handle, and a second position in which the latch permits removal of the handheld from the operating position. The vacuum also has a safety catch with a catch member on the handle and a second member on the handheld. The catch members resiliently hold the handheld unit on the handle in a partially-removed position. | 09-30-2010 |
| 20100293743 | Vacuum Cleaner with Filter Cleaning - A vacuum cleaner with a vacuum, a filtering unit, switching means for switching between a vacuum cleaning and filter cleaning modes, and a separating unit. In the vacuum cleaning mode, the vacuum forces a first air stream in a first air stream path through the filtering unit, in a first direction, to filter out dust from the dust laden air stream. In the filter cleaning mode, the vacuum forces a second air stream in a second air stream path through the filtering unit, in a second direction reverse to the first direction, to remove dust from the filtering unit. In the filter cleaning mode, the separating unit is in the air path between the vacuum and the filtering unit to separate dust removed from the filtering unit. In the vacuum cleaning mode, the separating unit is not in an air stream path. | 11-25-2010 |
| 20100306955 | Filter Cleaning System for a Vacuum Cleaner - A vacuum cleaner dust separation unit having a cyclone chamber ( | 12-09-2010 |
| 20100325834 | CYCLONE-LIKE SEPARATOR FOR A VACUUM CLEANER - A cyclone separator for a vacuum cleaner. The separator has a cyclone chamber, an air entrance device having a flow passage arrangement therethrough for introducing an air stream into the cyclone chamber in a manner that causes the air stream to swirl in the cyclone chamber to remove dust from the air stream, and an air outlet for emitting the air stream from the cyclone chamber. The entrance device has a control member that is operable to alter the flow passage arrangement such that one or more properties of the air stream in the cyclone chamber are affected by the alteration. The flow passage arrangement has a first path and a second path, and the control member is operable to alter the flow passage arrangement by redirecting the air stream from the first path to the second path. | 12-30-2010 |
