Abstract

A hand-held cleaning appliance includes a suction conduit, an airflow generator for generating an airflow along the suction conduit, a separating apparatus in communication with the suction conduit for separating dirt and dust from the airflow, a power source for supplying power to the airflow generator and a handgrip enabling a user to maneuver the hand-held cleaning appliance. The handgrip has a first end and a second end. The airflow generator is arranged directly adjacent the first end of the handgrip and the power source is arranged adjacent the second end of the handgrip. 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, an airflow generator generating an airflow along the suction conduit, a separating apparatus in communication with the suction conduit for separating dirt and dust from the airflow, a handgrip enabling a user to maneuver the hand-held cleaning appliance, the handgrip having a first end, a second end and a longitudinal axis, and a power source arranged adjacent the second end of the handgrip for supplying power to the airflow generator,

wherein the airflow generator is arranged directly adjacent the first end of the handgrip, the longitudinal axis passes through at least a part of the airflow generator and the handgrip lies between the airflow generator and the power source.

2. The hand-held cleaning appliance of claim 1, wherein the power source is arranged directly adjacent the second end of the handgrip.

3. The hand-held cleaning appliance of claim 1 or 2, wherein the longitudinal axis passes through at least a part of the power source.

4. The hand-held cleaning appliance of claim 1 or 2, wherein the airflow generator is arranged above the handgrip and the power source is arranged below the handgrip.

5. The A hand-held cleaning appliance of claim 1 or 2, wherein the suction conduit has a suction opening which is located remote from the handgrip.

6. The hand-held cleaning appliance of claim 5, wherein the separating apparatus is located between the suction opening and the handgrip.

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

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

9. The hand-held cleaning appliance of claim 7, wherein the trigger switch includes a resilient member configured for biasing the trigger switch into an off position.

10. The hand-held cleaning appliance of claim 1 or 2, wherein the power source is removably attached to the second end of the handgrip.

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

12. A hand-held vacuum cleaner comprising the cleaning appliance of claim 1 or 2.

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

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