Abstract

A multi-use vacuum cleaner capable of use as an upright vacuum or as a detachable vacuum module further comprising a cyclonic dirt separator has a detachable vacuum module selectively mounted to the base and support member of an upright vacuum cleaner. The vacuum module includes the vacuum motor, motor driven fan, cyclonic dirt separator and hose. The vacuum cleaner may be operated as an upright vacuum, or alternatively, the module can be separated from the base assembly and may be used independently of and at a great distance from the base assembly for a wide variety of cleaning purposes.

Claims

1. A vacuum cleaner comprising:

a foot assembly having a suction nozzle and a working air conduit connected at one end to the suction nozzle, and adapted to move along a surface to be cleaned;

an upright handle assembly pivotally mounted to said foot assembly for manipulation of the foot assembly along the surface to be cleaned and including;

an elongated structural support comprising a pair of spaced tubes pivotally mounted at a lower portion to the foot assembly and forming a handle grip at an upper portion;

a portable cleaning module detachably mounted as a unit to the elongated structural support between the spaced tubes and comprising;

a module housing;

a cyclone separation chamber into which dirt laden air is tangentially introduced through an inlet thereto and mounted in the module housing for separating dust and dirt from dirt-laden air;

a suction conduit having a first end connected to the module housing in fluid communication with the inlet of the cyclone separation chamber and a coupling at a second end adapted to be removably connected to another end of the working air conduit; and

a motor-driven fan supported in the module housing for creating suction within the suction conduit and for moving the dirt laden air to the inlet of the cyclone separation chamber; and

whereby when the portable cleaning module is mounted to the elongated structural support, the vacuum cleaner functions as an upright vacuum cleaner and the motor-driven fan draws dirt-laden air from the suction nozzle in the foot assembly through the suction conduit and moves the dirt-laden air to the inlet of the cyclone separation chamber, and wherein when the portable cleaning module is removed from the elongated structural support, the vacuum cleaner functions as a portable vacuum cleaner and the motor-driven fan draws dirt laden air from the second end of the suction conduit and moves to the inlet of the cyclone separation chamber.

2. The vacuum cleaner according to claim 1 wherein the suction conduit is at least in part flexible for movement of the second end thereof with respect to the module housing during use of the portable cleaning module when it is detached from the elongated structural support.

3. The vacuum cleaner according to claim 2 wherein the cyclone separation chamber has an outlet and the motor driven fan has an inlet connected to the cyclone separator chamber outlet.

4. The vacuum cleaner according to claim 2 wherein the motor driven fan has an inlet connected to the first end of the suction conduit and an outlet connected to the cyclone separator chamber inlet.

5. The vacuum cleaner according to claim 3 wherein the portable cleaning module further includes a dirt cup removably mounted in the module housing beneath the cyclone separation chamber to collect dirt separated from air therein.

6. The vacuum cleaner according to claim 5 wherein the module housing further includes a handle integrally formed at an upper portion thereof.

7. The vacuum cleaner according to claim 1 and further comprising a module platform mounted to the elongated structural support and including an opening at an upper surface thereof, the opening forms the other end of the working air conduit and the suction conduit second end is removably coupled to the opening.

8. The vacuum cleaner according to claim 1 wherein the module housing further includes a handle for hand carrying the module.

9. The vacuum cleaner according to claim 8 wherein the handle is at an upper portion of the module housing.

10. A vacuum cleaner comprising:

a foot assembly having a suction nozzle and a working air conduit connected at one end to the suction nozzle, and adapted to move along a surface to be cleaned;

an upright handle assembly pivotally mounted to said foot assembly for manipulation of the foot assembly along the surface to be cleaned and including;

an elongated structural support pivotally mounted at a lower portion to the foot assembly and forming a handle grip at an upper portion;

a portable cleaning module detachably mounted as a unit to the elongated structural support and comprising;

a module housing;

a cyclone separation chamber into which dirt laden air is tangentially introduced through an inlet thereto and mounted in the module housing for separating dust and dirt from dirt-laden air;

a suction conduit having a first end connected to the module housing in fluid communication with the inlet of the cyclone separation chamber and a coupling at a second end adapted to be removably connected to another end of the working air conduit; and

a motor-driven fan supported in the module housing for creating suction within the suction conduit and for moving the dirt laden air through the cyclone separation chamber, the motor driven fan having an inlet connected to the first end of the suction conduit and an outlet connected to the cyclone separator chamber inlet; and

whereby when the portable cleaning module is mounted to the elongated structural support, the vacuum cleaner functions as an upright vacuum cleaner and the motor-driven fan draws dirt-laden air from the suction nozzle in the foot assembly through the suction conduit and moves the dirt-laden air to the inlet of the cyclone separation chamber, and wherein when the portable cleaning module is removed from the elongated structural support, the vacuum cleaner functions as a portable vacuum cleaner and the motor-driven fan draws dirt laden air from the second end of the suction conduit and moves the dirt laden air to the inlet of the cyclone separation chamber.

11. The vacuum cleaner according to claim 10 wherein the suction conduit is at least in part flexible for movement of the second end thereof with respect to the module housing during use of the portable cleaning module when it is detached from the elongated structural support.

12. The vacuum cleaner according to claim 10 wherein the portable cleaning module further includes a dirt cup removably mounted in the module housing beneath the cyclone separation chamber to collect dirt separated from air therein.

13. The vacuum cleaner according to claim 10 wherein the module housing further includes a handle integrally formed at an upper portion thereof.
