         3 . The household appliance according to  claim 1 , wherein:
 the stovetop extends along the width direction for a first width value;   the suction chamber extends along the width direction for a second width value,   the suction chamber and the stovetop extend overlapping vertically in the width direction for a third width value greater than 50% of the first width value.   
     
     
         4 . The household appliance according to  claim 1 , wherein:
 the stovetop extends along the depth direction for a first depth value;   the suction chamber extends along the depth direction for a second depth value,   the suction chamber and the stovetop extend overlapping vertically in the depth direction for a third depth value greater than 30% of the first width value.   
     
     
         5 . The household appliance according to  claim 1 , wherein:
 the stovetop comprises a support portion adapted to support food containers and a bottom portion opposite to the support surface along the height direction,   the suction chamber is delimited above by the bottom portion of the stovetop.   
     
     
         6 . A household appliance according to  claim 1 , extending along the depth direction between a front portion and a rear portion, wherein:
 the box-like body is arranged in said rear portion of the appliance;   the manifold extends along the depth direction between the front portion and the rear portion of the household appliance.   
     
     
         7 . The household appliance according to  claim 1 , wherein the manifold comprises a bottom delimiting the suction chamber below, said bottom having a further connection opening which can be associated with the connection opening of the box-like body for fluidic connection of the suction chamber and the internal volume. 
     
     
         8 . The household appliance according to  claim 7 , wherein the further connection opening extends along the width direction for the entire extension in the width direction of the suction chamber. 
     
     
         9 . The household appliance according to  claim 6 and claim 7 , wherein the further connection opening is arranged in the rear portion of the household appliance. 
     
     
         10 . The household appliance according to  claim 1 , wherein the filter unit comprises a first and a second odour filter arranged on opposite sides of the grease filter along the width direction or the depth direction, said fluid-dynamic path having a bifurcation downstream of the suction opening and defining a first path through the first odour filter and a second path through the second odour filter. 
     
     
         11 . The household appliance according to  claim 1 , wherein the filter unit is arranged in a central region of the manifold along the length direction and/or the width direction.
