Abstract

A domestic appliance such as a cyclonic vacuum cleaner includes a component such as separating apparatus, carried by a chassis. A catch is provided and is operable to release the component from the chassis. The component and the chassis are able to move slightly with respect to each other. When the appliance is lifted, lugs on the separating apparatus move into slots on the chassis so as to inhibit release of the catch when the appliance is lifted. Thus, accidental release of the separating apparatus from the chassis is avoided.

Claims

1. A domestic appliance comprising a component carried by a chassis and a catch operable to release the component from the chassis, wherein a portion of the catch on the component is configured to move with respect to another portion of the catch on the chassis when the appliance is lifted so as to inhibit release of the catch.

2. An appliance as claimed in claim 1, wherein the portion of the catch comprises a first lug and a slot configured so as to engage each other when the appliance is lifted.

3. An appliance as claimed in claim 1 or 2, further comprising a second lug and slot arranged to engage each other when the appliance is lifted.

4. An appliance as claimed in claim 2, wherein the first or second lug and slot are configured so as to disengage from each other when the appliance is placed on a surface.

5. An appliance as claimed in claim 2, wherein the lug is provided on the component and the slot is provided on the chassis.

6. An appliance as claimed in claim 2, wherein the catch comprises a pivotable member on one of the component and the chassis configured so as to releasably engage in a lip on the other of the component and the chassis.

7. An appliance as claimed in claim 6, wherein the pivotable member includes a manually operable button for releasing the catch.

8. An appliance as claimed in claim 6 or 7, wherein the pivotable member releasably engages the lip against a force of a resilient member.

9. An appliance as claimed in claim 2, further comprising a handle for carrying the appliance.

12. An appliance as claimed in claim 2, in which the component comprises a separating apparatus for separating dirt and dust from an airflow.

13. An appliance as claimed in claim 12, wherein the separating apparatus further comprises a chamber for collecting the dirt and dust.

14. An appliance as claimed in to claim 12 or 13, further comprising a handle for carrying the appliance when the separating apparatus is attached to the chassis and for carrying the separating apparatus when it is released from the chassis.

15. A cyclonic vacuum cleaner, comprising the appliance of claim 2, 12 or 13.

16. An appliance as claimed in claim 3, wherein the first or second lug and slot are configured so as to disengage from each other when the appliance is placed on a surface.

17. An appliance as claimed in claim 4, wherein the lug is provided on the component and the slot is provided on the chassis.

18. An appliance as claimed in claim 17, wherein the catch comprises a pivotable member on one of the component and the chassis configured so as to releasably engage in a lip on the other of the component and the chassis.

19. An appliance as claimed in claim 18, wherein the pivotable member includes a manually operable button for releasing the catch.

20. An appliance as claimed in claim 18 or 19, wherein the pivotable member releasably engages the lip against a force of a resilient member.

21. A cyclonic vacuum cleaner, comprising the appliance of claim 14.
