Filter unit for a fume extraction device, and combination appliance having a cooktop and a fume extraction device having a filter unit

1. A filter unit for a fume extraction device, said filter unit comprising:

a filter body having a filter element;

a collecting region which is situated below the filter body and at least partially surrounds the filter body for collecting a liquid to prevent the liquid from passing through the filter body;

an upper region formed with an air inlet opening to let in air that is suctioned by the fume extraction device, said air inlet opening at least partially surrounding the filter body; and

a bottom side provided with an air outlet opening to let air out of the filter unit to the fume extraction device,

wherein the filter body forms a hollow body which is open at least at the bottom side, said air outlet opening of the filter unit being formed in a lower face of the hollow body.

2. The filter unit of claim 1 , wherein the filter element is located in the filter unit in a direction which is inclined relative to a horizontal.

3. The filter unit of claim 1 , wherein the filter element is located in the filter unit in a vertical direction.

4. The filter unit of claim 1 , wherein the filter body has a round or quadrangular cross section.

5. The filter unit of claim 1 , further comprising a filter holder configured to hold the filter body and to at least partially surround the filter body, said collecting region constituting a bottom of the filter holder, said filter body being received in the filter holder.

6. The filter unit of claim 1 , wherein the collecting region has an upper edge which at least in part forms an overflow edge for overflow of liquid, said overflow edge being disposed in spaced-apart relation to the filter element.

7. The filter unit of claim 1 , further comprising a cover configured to at least cover a top of the filter body.

8. The filter unit of claim 7 , wherein the cover protrudes on at least one side over an edge of the top of the filter body.

9. The filter unit of claim 1 , further comprising an overflow container configured to surround at least one part of the collecting region.

10. The filter unit of claim 9 , wherein the overflow container is at least partially below the at least one part of the collecting region.

11. The filter unit of claim 9 , wherein a bottom of the overflow container is spaced below a bottom of the at least one part of the collecting region.

12. A combination appliance, comprising:

a cooktop,

a fume extraction device arranged below the cooktop,

a filter unit comprising:

a filter body having a filter element;

a collecting region which is situated below the filter body and at least partially surrounds the filter body for collecting a liquid to prevent the liquid from passing through the filter body;

an upper region formed with an air inlet opening to let in air that is suctioned by the fume extraction device, said air inlet opening at least partially surrounding the filter body;

a bottom side provided with an air outlet opening to let air out of the filter unit to the fume extraction device; and

an overflow container configured to surround at least one part of the collecting region,

wherein the filter body forms a hollow body which is open at least at the bottom side, said air outlet opening of the filter unit being formed in a lower face of the hollow body.

13. The combination appliance of claim 12 , wherein the at least one part of the collecting region forms an overflow edge.

14. The combination appliance of claim 12 , wherein the overflow container is fixedly connected to the combination appliance.

15. The combination appliance of claim 12 , wherein the overflow container is at least partially below the at least one part of the collecting region.

16. The combination appliance of claim 12 , wherein a bottom of the overflow container is spaced below a bottom of the at least one part of the collecting region.

17. The combination appliance of claim 12 , wherein the fume extraction device is arranged directly below the air inlet opening of the filter unit.
