Abstract

A vacuum appliance is provided including a dirt collection container for sucked-in vacuumed material, a suction unit for subjecting the dirt collection container to the action of negative pressure via a suction chamber, at least one filter element between the dirt collection container and the suction chamber in the flow direction of the air sucked in by the suction unit, at least one rechargeable battery for providing electrical energy for the suction unit, and at least one battery receptacle for holding the battery on the vacuum appliance. The vacuum appliance includes a filter cover transferrable from a closed position in which the filter element is covered, to a removal position in which the filter element is removable from and insertable into the vacuum appliance on the clean space side, and vice versa, and which filter cover includes the battery receptacle for the battery.

First claim

That which is claimed:

1. A vacuum appliance comprising a dirt collection container for sucked-in vacuumed material, a suction chamber, a suction unit for subjecting the dirt collection container to the action of negative pressure via the suction chamber, at least one filter element situated in an opening between the dirt collection container and the suction chamber, with respect to the flow direction of the air which is sucked in by the suction unit, the at least one filter element comprising a dirty side facing the dirt collection container and a clean side facing the suction chamber, the vacuum appliance further comprising at least one rechargeable battery for providing electrical energy for the suction unit, and at least one battery receptacle for holding the at least one battery on the vacuum appliance, wherein the vacuum appliance includes a filter cover which is transferrable from a closed position in which the at least one filter element is covered, to a removal position in which the at least one filter element is removable from and insertable into the vacuum appliance, wherein the clean side of the filter element is accessible when the filter cover is in the removal position, and which filter cover comprises the at least one battery receptacle for the at least one battery.

2. The vacuum appliance according to claim 1 , wherein the at least one battery receptacle is situated on a side of the filter cover facing away from the suction chamber.

3. The vacuum appliance according to claim 1 , wherein the at least one battery receptacle is situated on a top side of the filter cover.

4. The vacuum appliance according to claim 1 , wherein the vacuum appliance includes a filter cleaning device for cleaning the at least one filter element.

5. The vacuum appliance according to claim 4 , wherein the filter cleaning device is mounted on the filter cover.

6. The vacuum appliance according to claim 4 , wherein the filter cleaning device is mounted on the filter cover and, in the closed position thereof, abuts against an edge of the at least one filter element to seal the filter element within the opening.

7. The vacuum appliance according to claim 1 , wherein the filter cover is mounted on the vacuum appliance so as to be pivotable about a pivot axis.

8. The vacuum appliance according to claim 1 , wherein the vacuum appliance includes an arresting device for arresting the filter cover in the removal position.

9. The vacuum appliance according to claim 1 , wherein the vacuum appliance includes a battery compartment in which the at least one battery and the at least one battery receptacle are located, as well as a battery compartment cover which is transferrable from a closed position in which the battery compartment cover closes the battery compartment, into an open position in which the battery compartment is open, and vice versa.

10. The vacuum appliance according to claim 9 , wherein the vacuum appliance includes an arresting device for arresting the battery compartment cover in the open position.

11. The vacuum appliance according to claim 10 , wherein the battery compartment cover is arrestable in the open position only when the at least one battery has been removed from the battery compartment.

12. The vacuum appliance according to claim 9 , wherein the filter cover in the removal position and the battery compartment cover in the open position are arrestable against one another to prevent transfer into the respective closed position.

13. The vacuum appliance according to claim 12 , wherein, apart from the filter cover, no further arresting device for arresting the battery compartment cover is provided, and that, apart from the battery compartment cover, no further arresting device for arresting the filter cover is provided.

14. The vacuum appliance according to claim 9 , wherein the battery compartment cover is mounted on the vacuum appliance so as to be pivotable about a pivot axis.

15. The vacuum appliance according to claim 14 , wherein the pivot axis about which the battery compartment cover is pivotable is different from another pivot axis about which the filter cover is pivotably mounted on the vacuum appliance.

16. The vacuum appliance according to claim 1 , wherein the vacuum appliance includes a cooling device for cooling the at least one battery.

17. The vacuum appliance according to claim 16 , wherein the cooling device includes at least one cooling air duct for cooling air passing through the at least one battery, which cooling air duct has at least one inlet opening, for the cooling air, at the at least one battery receptacle.

18. The vacuum appliance according to claim 17 , wherein the at least one inlet opening is formed as a through-opening in a support surface for the at least one battery in the at least one battery receptacle, the through-opening at least partially overlapping a housing opening of the at least one battery.

19. The vacuum appliance according to claim 17 , wherein the filter cover is configured, at least in part, as a hollow body which forms the at least one exhaust air duct.

20. The vacuum appliance according to claim 17 , wherein the cooling device includes at least one fan wheel for conveying cooling air for the at least one battery and/or for pulling cooling air through the at least one battery.

21. The vacuum appliance according to claim 20 , wherein the at least one fan wheel is situated in the at least one cooling air duct of the cooling device.

22. The vacuum appliance according to claim 1 , wherein the vacuum appliance is a hybrid vacuum cleaner having a connecting cable which is connectable to a energy supply network for providing electrical energy to the suction unit.

23. The vacuum appliance according to claim 12 , wherein the battery compartment cover is arrestable in the open position only when the at least one battery has been removed from the battery compartment.

24. A vacuum appliance comprising a dirt collection container for sucked-in vacuumed material, a suction unit for subjecting the dirt collection container to the action of negative pressure via a suction chamber, at least one filter element situated between the dirt collection container and the suction chamber in the flow direction of the air which is sucked in by the suction unit, at least one rechargeable battery for providing electrical energy for the suction unit, and at least one battery receptacle for holding the at least one battery on the vacuum appliance, wherein the vacuum appliance includes a filter cover which is transferrable from a closed position in which the at least one filter element is covered, to a removal position in which the at least one filter element is removable from and insertable into the vacuum appliance on the clean space side, and vice versa, and which filter cover comprises the at least one battery receptacle for the at least one battery,
wherein the vacuum appliance includes a battery compartment in which the at least one battery and the at least one battery receptacle are located, as well as a battery compartment cover which is transferrable from a closed position in which the battery compartment cover closes the battery compartment, into an open position in which the battery compartment is open, and vice versa, and
wherein the vacuum appliance includes an arresting device for arresting the battery compartment cover in the open position.

25. The vacuum appliance according to claim 24 , wherein the
