The collecting container includes an opening configured to receive at least part of an edge of the grease filter. The collecting container has an interior defined by a width which is greater than a thickness of the grease filter in a region in which the grease filter is located in the interior of the collecting container. ## Claims ### Claim 1 A filter device for a vapor extraction device, said filter device comprising: a grease filter; a collecting container for collecting liquid, said collecting container including an opening configured to receive at least part of an edge of the grease filter, said collecting container having an interior defined by a width which is greater than a thickness of the grease filter in a region in which the grease filter is located in the interior of the collecting container, and a deflector element configured to partially cover the opening of the collecting container. ### Claim 2 (depends on 1) The filter device of claim 1, wherein the grease filter has a V-shaped configuration which defines a tip, said collecting container enclosing the grease filter at the tip of the V-shape. ### Claim 3 (depends on 1) The filter device of claim 1, wherein the grease filter is designed to fold. ### Claim 4 (depends on 1) The filter device of claim 1, wherein the grease filter comprises at least two filter elements, which are connected pivotably to the collecting container. ### Claim 5 (depends on 1) The filter device of claim 1, wherein the grease filter is connected to the collecting container in a non-releasable manner. ### Claim 6 (depends on 1) The filter device of claim 1, wherein the deflector element is a web, which points from an upper edge of the collecting container into the opening of the collecting container. ### Claim 7 (depends on 6) The filter device of claim 6, wherein the collecting container is an open rail having an arm, said web being provided at a free end of the arm of the rail. ### Claim 8 (depends on 6) The filter device of claim 6, wherein the deflector element is displaced away from the collecting container at an open end of the collecting container and moved inwards on a side edge of the opening of the collecting container. ### Claim 9 (depends on 1) The filter device of claim 1, wherein the deflector element is an L-profile defining free ends, said deflector element being arranged such that the free ends of the profile face the opening of the collecting container. ### Claim 10 A vapor extraction device, comprising: a suction opening to allow sucking of air downwards away from a space above a cooktop; a filter device for cleaning the air, said filter device comprising a grease filter and a collecting container for collecting liquid, said collecting container including an opening configured to receive at least part of an edge of the grease filter, said collecting container having an interior defined by a width which is greater than a thickness of the grease filter in a region in which the grease filter is located in the interior of the collecting container, and a deflector element configured to partially cover the opening of the collecting container. ### Claim 11 (depends on 10) The vapor extraction device of claim 10, wherein the filter device is arranged below the suction opening. ### Claim 12 (depends on 10) The vapor extraction device of claim 10, wherein the grease filter has a V-shaped configuration which defines a tip, said collecting container enclosing the grease filter at the tip of the V-shape. ### Claim 13 (depends on 10) The vapor extraction device of claim 10, wherein the grease filter is designed to fold. ### Claim 14 (depends on 10) The vapor extraction device of claim 10, wherein the grease filter comprises at least two filter elements, which are connected pivotably to the collecting container. ### Claim 15 (depends on 10) The vapor extraction device of claim 10, wherein the grease filter is connected to the collecting container in a non-releasable manner. ### Claim 16 (depends on 10) The vapor extraction device of claim 10, wherein the deflector element is a web, which points from an upper edge of the collecting container into the opening of the collecting container. ### Claim 17 (depends on 16) The vapor extraction device of claim 16, wherein the collecting container is an open rail having an arm, said web being provided at a free end of the arm of the rail. ### Claim 18 (depends on 16) The vapor extraction device of claim 16, wherein the deflector element is displaced away from the collecting container at an open end of the collecting container and moved inwards on a side edge of the opening of the collecting container. ### Claim 19 (depends on 10) The vapor extraction device of claim 10, wherein the deflector element is an L-profile defining free ends, said deflector element being arranged such that the free ends of the profile face the opening of the collecting container.
