| 20090235482 | Cyclonic Vacuum Cleaner - A cyclonic vacuum cleaner includes a body portion, a nozzle portion and a dirt cup which is removable from the body portion. The dirt cup collects dirt and other debris separated by a cyclone and a cyclone slinger portion in the body portion. A main filter may be housed in a transparent filter door downstream of the cyclone. The dirt cup may be inserted into and sealingly held within the body portion by using a rotational caroming structure. | 09-24-2009 |
| 20100050876 | Sodium Bicarbonate Vacuum Bag Inserts - A vacuum cleaner bag filter with one or more filter walls forming a generally air permeable enclosure having a bag opening through it, and a flange attached to the one or more filter walls to cover the bag opening. The filter walls have a working surface area through which air can pass during use, and the flange is a relatively rigid structure having an air inlet passing into the air permeable enclosure. One or more deodorizing sheets are attached to an inner surface of the one or more filter walls. The deodorizing sheets include a first sheet layer, and sodium bicarbonate particles operatively associated with the first sheet layer. The deodorizing sheets may cover less than about 30% of the working surface area, a single deodorizing sheet may be provided, and the deodorizing sheets may be attached to the filter walls by an air impermeable adhesive that covers at least about 5% of the surface area of the deodorizing sheets. Also provided is a vacuum cleaner filter having a filter and a deodorizing sheet attached thereto by an air-impermeable adhesive. | 03-04-2010 |
| 20100175559 | Vacuum Cleaner Filter Assembly - A vacuum cleaner filter assembly having a filter frame with a frame sidewall defining an enclosed perimeter. A filter is mounted in the filter frame and has a surface through which air can pass. A deodorizer chamber has a first sidewall connected to a first portion of the frame sidewall, and a second sidewall connected a second portion of the frame sidewall. The deodorizer chamber has a filter-facing portion facing a first portion of the filter, and defines a passage from there to a portion of the chamber not facing the filter. A number of deodorizer pellets are contained in the chamber. The filter assembly has parallel first and second air paths. The first path extends through the first portion of the filter and the chamber. The second path extends through a second portion of the filter that is not covered by the pellet chamber and not through the chamber. | 07-15-2010 |
| 20100212106 | Cyclonic Vacuum Cleaner - A cyclonic vacuum cleaner includes a body portion, a nozzle portion and a dirt cup which is removable from the body portion. The dirt cup collects dirt and other debris separated by a cyclone and a cyclone slinger portion in the body portion. A main filter may be housed in a transparent filter door downstream of the cyclone. The dirt cup may be inserted into and sealingly held within the body portion by using a rotational caroming structure. | 08-26-2010 |
| 20100218340 | Vacuum Cleaner Handle Lock and Valve Control - A vacuum cleaner having a base with a first air inlet, a rear housing, a removable handle and a socket on the housing to receive the handle. The handle has a grip, a second air inlet, and a hose connected to the second air inlet. The vacuum has a valve with a first inlet connected to the first air inlet, a second inlet connected to the flexible hose, a valve outlet connected to a vacuum fan, and a valve member that moves to connect the valve outlet to either inlet. The vacuum has a handle latch having one position in which it engages the removable handle to hold it in the socket and places the valve in one position, and a second position in which it releases the handle and places the valve member the other position. | 09-02-2010 |
| 20110056045 | Dirt Cup Latch Mechanism - A vacuum cleaner dust cup having a sidewall surrounding an open bottom end, and a shelf extending from the sidewall. A lid is pivotally connected to the cup adjacent the bottom end and is movable between a first position in which it covers the open bottom end, and a second position in which it does not cover the open bottom end. A latch is attached to the lid and has a contact surface adapted to engage the shelf to hold the lid in the first position. An actuator is mounted adjacent the cup sidewall and is movable in a first direction to move the contact surface of the latch out of engagement with the shelf to allow the lid to move about the hinge to the second position. In some embodiments, the actuator does not apply any substantial force to move the lid out of the first position. | 03-10-2011 |
| 20110061540 | Vacuum Cleaner Filter Assembly - A vacuum cleaner filter assembly having a filter frame with a frame sidewall defining an enclosed perimeter. A filter is mounted in the filter frame and has a surface through which air can pass. A deodorizer chamber has a first sidewall connected to a first portion of the frame sidewall, and a second sidewall connected a second portion of the frame sidewall. The deodorizer chamber has a filter-facing portion facing a first portion of the filter, and defines a passage from there to a portion of the chamber not facing the filter. A number of deodorizer pellets are contained in the chamber. The filter assembly has parallel first and second air paths. The first path extends through the first portion of the filter and the chamber. The second path extends through a second portion of the filter that is not covered by the pellet chamber and not through the chamber. | 03-17-2011 |
