The fume extraction device includes a blower located below the suction opening and having an air inlet opening, and a filter unit located at the suction opening and having a grease filter. The fume extraction device includes a separating plate which separates the filter unit from the blower located below the filter unit. ## Claims ### Claim 1 A combination appliance, comprising: a hob including a cooking module and having a suction opening; and a fume extraction device arranged, at least in part, below the cooking module in a vertical direction perpendicular to a plane of the cooking module, wherein the fume extraction device comprises: a blower: an air inlet opening; a filter unit arranged at the suction opening and above the blower in the vertical direction, the filter unit having a grease filter; and a separating plate arranged below the filter unit and above the blower in the vertical direction, the separating plate separating the filter unit from the blower. ### Claim 2 (depends on 1) The combination appliance of claim 1, wherein the separating plate has a recess comprising an upright edge. ### Claim 3 (depends on 1) The combination appliance of claim 1, wherein the separating plate is part of a housing for receiving the filter unit, said housing including a side wall configured as a grille. ### Claim 4 (depends on 1) The combination appliance of claim 1, wherein the grease filter is arranged in an inclined manner in the filter unit. ### Claim 5 (depends on 1) The combination appliance of claim 1, wherein the grease filter has a V-shaped configuration defining an open side which is oriented upwardly. ### Claim 6 (depends on 1) The combination appliance of claim 1, wherein the grease filter is foldable. ### Claim 7 (depends on 1) The combination appliance of claim 1, further comprising a collection container connected to the grease filter, said grease filter having an underside which is held in the collection container. ### Claim 8 (depends on 1) The combination appliance of claim 1, wherein the filter unit includes an odor filter which is arranged laterally adjacent to the grease filter in the filter unit. ### Claim 9 (depends on 8) The combination appliance of claim 8, wherein the odor filter is releasably held and has a thickness which is less than or equal to a width of the suction opening. ### Claim 10 (depends on 8) The combination appliance of claim 8, wherein the odor filter has a length which is greater than a length of the suction opening, said odor filter being configured in multiple parts. ### Claim 11 (depends on 1) The combination appliance of claim 1, further comprising a hob electronics unit and a fume extraction device electronics unit, with both the hob electronics unit and the fume extraction device electronics unit being arranged laterally relative to the filter unit above the blower. ### Claim 12 (depends on 11) The combination appliance of claim 11, wherein the hob electronics unit has a width which is greater than a width of the fume extraction device electronics unit, said hob electronics unit being arranged above the fume extraction device electronics unit. ### Claim 13 (depends on 1) The combination appliance of claim 1, further comprising an appliance housing configured to jointly receive the cooking module of the hob and the blower, the filter unit and the separating plate of the fume extraction device. ### Claim 14 A combination appliance, comprising: a hob including a cooking module and a suction opening; and a fume extraction device arranged, at least in part, below the cooking module in a vertical direction perpendicular to a plane of the cooking module, wherein the fume extraction device comprises: an air inlet opening; a filter unit arranged at the suction opening and comprising a grease filter; a separating plate arranged below the filter unit in the vertical direction; and a blower arranged below the separating plate and the filter unit in the vertical direction. ### Claim 15 (depends on 14) The combination appliance of claim 14, further comprising an odor filter arranged outside of the grease filter in a lateral direction, wherein the lateral direction is parallel to the plane of the cooking module and perpendicular to the vertical direction. ### Claim 16 (depends on 15) The combination appliance of claim 15, wherein the separating plate and an air inlet opening of the blower are separated by a spacing. ### Claim 17 (depends on 16) The combination appliance of claim 16, wherein the blower creates suction which draws air through the suction opening, then through the grease filter, then through the odor filter, then around lateral ends of the separating plate, then through the spacing, and then into the blower. ### Claim 18 (depends on 14) The combination appliance of claim 14, wherein a diameter of the grease filter is less than a diameter of the suction opening such that the grease filter is insertable through the suction opening. ### Claim 19 (depends on 15) The combination appliance of claim 15, wherein the grease filter and the odor filter extend vertically downward and away from the suction opening such that the grease filter and the odor filter do not block the suction opening.
