First Claim
Patent Images
1. An upright vacuum cleaner having a base module and a handle pivotally mounted thereto for pivotal movement about a pivot axis between an upright stored position and a reclining use position;
- the base module having a suction nozzle at a forward portion thereof;
at least one pair of wheels supporting the base for movement along a surface to be cleaned;
a filter bag mounted to the handle for recovering dirt from dirty air;
a suction source mounted to one of the handle and the base;
a working air conduit comprising a portion of the handle; and
a cyclonic dust separator comprising;
a cyclone body having an inlet opening and an outlet opening each connected to the working air conduit, the inlet opening being connected to the working air conduit in an upstream direction from the outlet opening, the cyclone body adapted to produce a cyclonic air current for separating dirt contained in working air entering the cyclone body through the inlet opening;
a cylindrical dirt-separating grille within said cyclonic dust separator between the inlet opening and outlet opening and having a plurality of holes through which working air passes between the inlet opening and outlet openings of the cyclone body;
a dirt-collecting tub removably mounted to the cyclone body for collecting dirt separated from the working air by the cyclonic air current of the cyclone body; and
an annular baffle plate mounted to a bottom portion of the dirt-separating grille and extending laterally thereof.

Abstract
An upright vacuum cleaner with a small cyclone separator is mounted on and in fluid communication with an elongated rigid tube that forms part of a working air conduit and also forms part of an upright handle that is pivotally mounted to a base module with a suction nozzle upstream from a conventional bag filter in a dirty air or clean air dust collection vacuum cleaner.

3. An upright vacuum cleaner having a base module and a handle pivotally mounted thereto for pivotal movement about a pivot axis between an upright stored position and a reclining use position;
-
the base module having a suction nozzle;
a filter bag removably mounted to the handle for movement therewith;
a working air conduit between the suction nozzle and the filter bag;
a suction source mounted to one of a lower portion of the handle and the base module and in communication with the suction nozzle and the filter bag for moving dust-laden air between the suction nozzle and through the filter bag; and
a cyclonic dust separator mounted in the working air conduit upstream of the filter bag for separating larger particles from the dust-laden air before the dust-laden air passes through the filter bag;
wherein the handle includes a rigid elongated tube that extends between the base module at a lower end and the filter bag at an upper end, the cyclonic dust separator is mounted to the rigid elongated tube, and the filter bag is mounted at an upper portion to the elongated tube for recovering dirt from dirty air and extends downwardly therefrom along at least a portion of the elongated tube. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13)
