Abstract

A hand-held cleaning appliance includes a suction conduit having a longitudinal axis, an airflow generator generating an airflow along the suction conduit, a separating apparatus arranged in communication with the suction conduit for separating dirt and dust from the airflow, a power source supplying power to the airflow generator and an elongate handle disposed between the airflow generator and the power source. The elongate handle is dimensioned and arranged to be gripped by a user'"'"'s hand and the elongate handle lies transverse to the longitudinal axis of the suction conduit. By providing a hand-held vacuum cleaner with such an arrangement, the hand-held vacuum cleaner is easier and more comfortable to manipulate in use.

Claims

1. A hand-held cleaning appliance comprising a suction conduit having a longitudinal axis, an airflow generator generating an airflow along the suction conduit, a separating apparatus arranged in communication with the suction conduit separating dirt and dust from the airflow, a power source supplying power to the airflow generator and an elongate handle disposed between the airflow generator and the power source and dimensioned and arranged to be gripped by a user'"'"'s hand, wherein the elongate handle lies transverse to the longitudinal axis of the suction conduit at an angle which is close to a right angle.

2. The hand-held cleaning appliance of claim 1, wherein the elongate handle lies at an angle to the longitudinal axis in the range of 80 to 90°

.

3. The hand-held cleaning appliance of claim 1 or 2, wherein the separating apparatus is located between the suction conduit and the elongate handle.

4. The hand-held cleaning appliance of claim 1 or 2, wherein the suction conduit has a suction opening and the longitudinal axis passes through the suction opening.

5. The hand-held cleaning appliance of claim 4, wherein the suction opening is remote from the elongate handle.

6. The hand-held cleaning appliance of claim 1 or 2, wherein a trigger switch is located on the elongate handle for switching the airflow generator on or off.

7. The hand-held cleaning appliance of claim 5, wherein the trigger switch is located on the side of the elongate handle which is closest to the suction opening.

8. The hand-held cleaning appliance of claim 6, wherein the trigger switch includes a resilient member for biasing the trigger switch into an off position.

9. The hand-held cleaning appliance of claim 1 or 2, wherein the separating apparatus comprises a cyclonic separator.

10. The hand-held cleaning appliance of claim 1 or 2, wherein the hand-held cleaning appliance is a hand-held vacuum cleaner.
