Abstract

A separating apparatus for a cleaning appliance, such as a vacuum cleaner, includes a separator for separating dirt and dust from a fluid flow and a collecting chamber arranged to collect dirt and dust separated by the separator. A first catch for opening a closure member on the collecting chamber is provided, with first releasing means for releasing this catch. There is also provided a second catch for releasing the collecting chamber from the separator and second releasing means for releasing the second catch. The second releasing means is inaccessible when the first catch is engaged. A cover associated with the first releasing means obscures the second releasing means until the first catch has been released. The invention prevents the user from accidentally releasing the collecting chamber from the separator when it was the user'"'"'s intention simply to empty dirt and dust from the collecting chamber.

Claims

1. A separating apparatus for a cleaning appliance, comprising a separator for separating dirt and dust from a fluid flow and a collecting chamber arranged to collect dirt and dust separated by the separator, a first catch for opening a closure member on the collecting chamber, a first releasing mechanism arranged to be capable of releasing the first catch, a second catch for releasing the collecting chamber from the separator and a second releasing mechanism arranged to be capable of releasing the second catch, in which the second releasing means is inaccessible when the first catch is engaged.

2. The separating apparatus as claimed in claim 1, in which the second releasing mechanism is configured to be at least partially obscured when the first catch is engaged.

3. The separating apparatus as claimed in claim 1 or 2, in which the second releasing mechanism is made inaccessible or is obscured by the first releasing mechanism.

4. The separating apparatus as claimed in claim 2, in which the first releasing mechanism is arranged to move from a first position, in which the first releasing mechanism obscures the second releasing mechanism, to a second position in which the second releasing mechanism is accessible and visible.

5. The separating apparatus as claimed in claim 1 or 2, in which the second releasing mechanism is made inaccessible or is obscured by part of the collecting chamber.

6. The separating apparatus as claimed in claim 5, in which the second releasing mechanism is made inaccessible or is obscured by part of the closure member.

7. The separating apparatus as claimed in claim 1 or 2, in which the first and second catches are spaced from one another.

8. The separating apparatus as claimed in claim 1 or 2, in which the first releasing mechanism comprises a manually operable actuating member which is located remotely from the closure member and wherein the first releasing mechanism is configured to operate to apply an opening force to the closure member.

9. The separating apparatus as claimed in claim 8, in which the first releasing mechanism comprises a push rod which is movable to firstly release the first catch and secondly to exert the opening force on the closure member.

10. The separating apparatus as claimed in claim 1 or 2, in which the closure member is attached by a pivot to the collecting chamber and the first releasing mechanism is configured to operate to apply an opening force to the closure member at a position which is spaced from the pivot.

11. The separating apparatus as claimed in claim 1 or 2, in which the second releasing mechanism comprises a user-operable button.

12. The separating apparatus as claimed in claim 1 or 2, in which the collecting chamber comprises a cyclonic separator.

13. A cleaning appliance comprising the separating apparatus as claimed in claim 1 or 2.

14. The cleaning appliance as claimed in claim 13, further comprising a main body, the separating apparatus being releasably held on the main body.

15. The cleaning appliance as claimed in claim 14, in which the separating apparatus is configured to be releasable from the main body by operating the first releasing mechanism.

16. The cleaning appliance as claimed in claim 13, in which the separating apparatus is held on the main body when the collecting chamber is released from the separating apparatus.
