  • Publication number: 20110265284
    Abstract: A vacuum cleaner with a blockage sensor and methods of identifying an obstructed airway in a vacuum are described. The vacuum cleaner has a motor and a circuit board to provide electrical current to the motor including an amperage flow sensor to determine the electrical current draw of the motor, and a blockage determiner to sample the electrical current draw and count the number of times the sampled electrical current draw exceeds a threshold amperage within a window of time. The blockage determiner can sense a blockage within the airflow path or the beater bar, and can optionally shut down the motor prior to motor failure.

  • Publication number: 20110265285
    Abstract: According to various embodiments, a method of reducing noise generated by a vacuum is described. The method comprises providing a vacuum comprising a motor including a motor shaft adapted to operate at a rotational speed of n; attaching a centripetal fan with t number of blades attached to the motor shaft; enclosing the fan between the motor and a motor housing end bracket disposed about the shaft, the motor housing end bracket defining an air input opposite an air output; wherein the variables of speed n and the number of blades t are selected so that a blade pass frequency (BPF) of the centripetal fan is greater than about 5000 Hertz, and the BPF is calculated as BPF=n*t/60. A vacuum implementing the method is also described.

  • Publication number: 20110265881
    Abstract: A vacuum cleaner with an automated diverter valve is described. The vacuum includes a handle, body, base, an automated diverter valve and air duct including two input ports. An automated diverter valve assembly at the junction of the dirty air intake within the base extends the air duct within the base and connects to the main air duct of the vacuum to the beater bar input and an attachment input. The automated diverter valve causes the air intake of the vacuum to be drawn from either the beater bar (floor) air input or the attachment input depending upon the position of the vacuum handle.

  • Publication number: 20110265282
    Abstract: A vacuum cleaner with a reduced frictional force between a vacuum base and a cleaning medium is described. The vacuum has a handle, yoke, body, and base. A handle and yoke distinct from, and behind, the base provides a moment arm anterior to the base when a force is applied. The handle and yoke assembly reduce the friction between the cleaning surface and the vacuum, allowing for larger motor and debris capturing capabilities, with easier handling and maneuverability resulting in advanced and superior cleaning capabilities.

  • Patent number: 4376313
    Abstract: The invention is an improvement in the structure of commodes or toilets to facilitate maintenance when the commode or toilet bowl becomes clogged with an obstruction of some type. The invention provides an easily accessible, removable, sealable, and replaceable access port at, near, or in the vicinity of the trap portion of the commode or toilet where the obstructions usually lodge, and where they are inaccessible without disconnecting and removing the commode or toilet from its sealed setting. The access port may be part of the commode or toilet bowl structure on commodes or toilet bowls with a front or rear trap. The invention eliminates the disconnecting and removal of the commode or toilet bowl and the subsequent resealing, resetting and reconnecting of the commode or toilet bowl.
