Abstract

A cleaning appliance comprising a main body and a separating apparatus including a dirt collector having a base that is openable that allows the dirt collector to be emptied. The cleaning appliance includes an actuator that is operable sequentially such that, during a first operation, the actuator causes the base to be opened and, during a second operation, the actuator causes the dirt collector to disengage from the separating apparatus. A single actuator is therefore used for two functions: firstly to open the dirt collector for emptying purposes and, secondly, to disengage the dirt collector from the separating apparatus for example for cleaning purposes. Such an arrangement is space efficient and intuitive for the user.

Claims

1. A cleaning appliance comprising a main body and a separating apparatus including a dirt collector having a base that is openable to allow the dirt collector to be emptied, wherein the cleaning appliance includes an actuator that is operable sequentially such that, during a first operation, the actuator causes the base to be opened and, during a second operation, the actuator causes the dirt collector to disengage from the separating apparatus.

2. The cleaning appliance of claim 1, wherein the base of the dirt collector is openable when the separating apparatus is coupled to the main body.

3. The cleaning appliance of claim 1, wherein the actuator is a user-operable button.

4. The cleaning appliance of claim 1, wherein the actuator includes a linkage member which, during the first operation, actuates a push rod that is engagable with the base.

5. The cleaning appliance of claim 4, wherein the linkage member is further operable, during the second operation, to engage a release member on the main body for retaining a lug on the dirt collector.

6. The cleaning appliance of claim 5, wherein the linkage member is rotatable between a first angular position in which the linkage member engages with the push rod and a second position in which the linking member engages with the release member.

7. The cleaning appliance of claim 6, wherein the linkage member rotates from the first to the second position after completion of the first operation of the actuator.

8. The cleaning appliance of claim 7, wherein the linkage member rotates from the first to the second position during the second operation of the actuator.

9. The cleaning appliance of claim 6, wherein the linkage member is biased into the second angular position.

10. The cleaning appliance of claim 9, wherein the pushrod includes a lip to retain the linkage member in the first angular position during the first operation of the actuator.

11. The cleaning appliance of claim 5, wherein during the second operation the release member is moved out of engagement with the lug on the dirt collector so as to allow the dirt collector to be disengaged from the separating apparatus.

12. The cleaning appliance of claim 11, wherein the release member includes a projection that, during the second operation, moves in synchronisation with the release member to push the lug away from the main body therefore to present the dirt collector for a user to remove from the separating apparatus.

13. The cleaning appliance of claim 1, wherein the main body includes a spine against which the dirt collector abuts when the separating apparatus is coupled to the main body.

14. The cleaning appliance of claim 13, wherein the actuator is slidably mounted to the spine.

15. The cleaning appliance of claim 1, wherein the actuator is arranged to be accessible from either side of the vacuum cleaner.

16. The cleaning appliance of claim 1, wherein the separating apparatus includes a cyclonic separator.

17. The cleaning appliance of claim 1, wherein the base of the dirt collector is openable only when the separating apparatus is decoupled from the main body.

18. The cleaning appliance of claim 17, wherein the actuator is also operable to release the separating apparatus from the main body.

19. The cleaning appliance of claim 17, wherein the actuator for opening the base and releasing the dirt collector from the separating apparatus is located on the separating apparatus.
