Abstract

A multi-use vacuum capable of use as an upright vacuum or as a canister vacuum is disclosed. A detachable vacuum module is selectively mounted to the foot and support member of an upright vacuum. The vacuum module includes the vacuum motor, motor-driven fan, vacuum bag and hose. The vacuum may be operated as an upright vacuum or, alternatively, the module can be separated from the foot and support member and may be used independently of and at a great distance from the foot and support member for a wide variety of cleaning purposes.

Claims

1. A vacuum cleaner comprising;

a foot housing;

a base pivotally mounted to said foot housing;

an elongated support member non-removably mounted at a lower portion to the base during typical use of the vacuum cleaner, the elongated support member being adapted for use in pushing and pulling the base and the foot housing along the floor; and

a portable cleaning module comprising;

a module housing;

a bag supported in the module housing for collecting dust and dirt;

a flexible conduit for conveying the collected dust and dirt from the foot housing to the bag, the conduit having a first end connected to the bag and a second end removably connected to the base; and

a motor-driven fan supported in the module housing for creating suction within the conduit through the bag to convey collected dust and dirt to the bag;

the module mounting the bag, conduit and motor-driven fan such that the bag, conduit and motor-driven fan are connected together as a unit, the module being selectively and removably mounted to the base at least through a mechanical interconnection such that the module can be separated from the foot housing, base and elongated support member and be operated as a portable vacuum cleaner and the module further is closely adjacent the elongated support member, extends upwardly along at least a portion of the length of the elongated support member and is adapted to pivot with the base and elongated support member relative the foot housing when the module is mounted to the base;

whereby the module can be operated as a portable vacuum cleaner independently of and separate from the foot housing, base and elongated support member when the module is separated from the base and the vacuum cleaner can be operated as an upright vacuum cleaner when the module is mounted to the base.

2. A vacuum cleaner according to claim 1 wherein the interconnection between the module housing and the base comprises a male connector formed on one of the base and the module housing and a female connector formed on the other of the base and the module housing.

3. A vacuum cleaner according to claim 2 wherein the interconnection between the module housing and the base further comprises a first electrical connector formed on one of the base and module housing and a second electrical connector formed on the other of the base and module housing, the first and second electrical connectors being selectively engaged to supply electrical current from the module to the foot housing when the module housing is mounted to the base.

4. A vacuum cleaner according to claim 3 wherein the conduit comprises a wand which is removably mounted in the module housing and connected to said base when the wand is mounted in the module housing and the module housing is mounted to the base.

5. A vacuum cleaner according to claim 1 wherein the interconnection between the module housing and the base comprises a male connector formed on one of the base and the module housing and a female connector formed on the other of the base and the module housing.

6. A vacuum cleaner according to claim 5 and further comprising a first electrical connector formed on one of the base and module housing and a second electrical connector formed on the other of the base and module housing, the first and second electrical connectors being selectively engaged to supply electrical current from the module to the foot housing.

7. A vacuum cleaner according to claim 1 wherein the conduit comprises a flexible hose and a wand, a distal end of the flexible hose being in fluid communication with the bag and a proximal end of the hose being in fluid communication with the wand and the wand is removably mounted to the module housing.

8. A vacuum cleaner according to claim 7 and further comprising a first recess formed on one side of the module housing for storing the wand and hose.

9. A vacuum cleaner according to claim 7 and further comprising a handle mounted to the wand and a second recess formed in a side of the module housing, the second recess being complementary in shape to the outside perimeter of the handle so that the wand is selectively mounted in the module housing through the interengagement of the handle and the second recess.

10. A vacuum cleaner according to claim 1 and further comprising an agitation member and an agitation member motor mounted in the floor suction component.

11. A vacuum cleaner according to claim 1 and further comprising an electrical cord electrically connected to the module, the cord supplying all of the electrical current necessary to operate the vacuum cleaner as an upright vacuum cleaner or to operate the module independently of the floor suction component and support member.

12. A vacuum cleaner according to claim 1 and further comprising a switch mounted to one of the base and the support member, the switch having first and second operable positions, wherein the switch is adapted to assume the first position when the support member is in a fully upright position relative to the foot housing and the switch is adapted to assume the second position when the support member is in a position other than the fully upright position relative to the foot housing, wherein in the first position, the switch prevents the flow of electrical current to an agitation motor mounted in the foot housing and in the second position, the switch completes and electrical circuit to supply electrical current to the agitation motor.

13. A vacuum cleaner according to claim 1 wherein the conduit comprises a wand which is removably mounted in the module housing and connected to said base when the wand is mounted in the module housing and the module housing is mounted to the base.

18. A vacuum cleaner according to claim 1 and further comprising a handle mounted to the top of the portable cleaning module, the handle being adapted to be grasped by the user when the portable cleaning module is separated form the base, foot housing and elongated support member.

14. A vacuum module for selectively mounting to a floor suction component, the module comprising;

a motor, a fan coupled to the motor to draw a suction, a conduit and a bag interconnected as a single unit, the module having a housing to support the motor and bag and the conduit being mounted at one end to the bag and comprising a wand and a hose;

the housing comprises an external mechanical connector for mechanically connecting the module to a floor suction component, an external coupler associated with the mechanical coupler, to couple the fan inlet to the floor suction component, a first recess formed on one side of the module housing for receiving the wand and hose, and a handle mounted to an upper portion of the housing;

whereby the module is adapted to selectively engage the floor suction component and to provide the suction necessary to operate the module and floor suction component as an upright vacuum, and the module is further adapted to operate independently of and separate from the floor suction component.

15. A vacuum module according to claim 14 further comprising a handle mounted to the wand and a second recess formed in a side of the module housing, the second recess being complementary in shape to the outside perimeter of the handle so that the wand is selectively mounted in the module housing through the interengagement of the handle and the second recess.

16. A vacuum module according to claim 15 wherein the handle is C-shaped.

17. A vacuum module according to claim 14 and further comprising an electrical cord electrically connected to the module, and an external electrical coupler mounted on the module housing in association with the external mechanical connector and connected to the electrical cord for supplying electrical current to the base, whereby the electrical cord can supply the electrical current necessary to operate the vacuum cleaner as an upright vacuum cleaner or to operate the module independently of the base, support member and foot housing.
