Patent number: 4656688Abstract: A housing for a hand vacuum cleaner having a front dust chamber and a rear motor chamber separated from each other by a baffle, a dust chamber cover linked at the baffle, and a tightly connected motor chamber cover. In the area adjacent to the motor chamber cover there is designed a handle hollow in the dust chamber cover. This handle hollow is partially covered by a handhold which may be arranged at the motor chamber cover as an integral part thereof. In another embodiment of the housing, the handhold is incorporated in the dust chamber cover. At the motor chamber cover there may be arranged a cross-piece projecting toward the dust chamber cover, covering the rear area of the handle hollow and supporting a cross-piece of the dust chamber cover, thus providing a particularly robust handhold.Type: GrantFiled: September 26, 1985Date of Patent: April 14, 1987Assignee: Progress-Elektrogerate Mauz & Pfeiffer GmbH & Co.Inventors: Gernot Jacob, Leon Radom

Patent number: 4654924Abstract: A control system for a vacuum cleaner comprising three separate sub-control systems located in a canister portion, a power nozzle floor cleaner portion and a suction hose handle portion respectively. The handle portion sub-control includes user input switches and indicator lights and it controls the other two sub-controls. The canister sub-control controls the energization and speed of a suction fan motor as well as sensing pressure levels in the canister and suction hose. The floor cleaner sub-control controls the energization of a beater brush motor as well as sensing the rotational speed of the beater brush and depth of carpeting pile. Microcomputers are used in each circuit and communication between the circuits is done in packet form on a third connector and one side of an AC power line. Diagnostic testing is also built into the control system.Type: GrantFiled: December 31, 1985Date of Patent: April 7, 1987Assignee: Whirlpool CorporationInventors: Edward H. Getz, Roger D. Burdi

Patent number: 4648149Abstract: An electric vacuum cleaner has a floor engaging unit, a generally vertically extending handle assembly pivotally affixed to the rear of the floor engaging unit, and a porous bag assembly mounted to the front of the handle assembly. The handle assembly is hollow to direct dust-laden air from the floor engaging unit to the bag assembly. A bottom plate, under the brush roll, has notches at its edges to enhance edge cleaning, and front wheels for the cleaner. Ridges are provided in the floor engaging unit to prevent improper assembly of the drive belt. The handle assembly is resiliently biased upwardly, and a release is provided thereon to enable relaxation of forces on the porous bag of the porous bag assembly, to facilitate changing of the bag.Type: GrantFiled: March 10, 1986Date of Patent: March 10, 1987Assignee: National Union Electric Corp.Inventors: Leonard Hampton, Samuel E. Hohulin

Patent number: 4644605Abstract: A vacuum cleaner convertible between an upright vacuum cleaner and a portable hand carried vacuum cleaner. The conversion is accomplished by means of a handle pivotally mounted for selective movement between an open position extending from the body of the unit for manipulation thereof in an upright floor carried vacuum operation, and a closed position overlying the body of the unit wherein the handle and housing cooperate to form a handgrip of discrete length for manipulation thereof in a portable hand carried vacuum cleaning operation. The handle automatically latches upon opening and closing. The vacuum cleaner also includes a dirt reservoir and filter bag assembly carried by the body of the unit and removable from the body of the unit and separable from each other for ease of cleaning.Type: GrantFiled: March 25, 1985Date of Patent: February 24, 1987Assignee: Bissell Inc.Inventors: Michael S. Joss, David E. McDowell
