• at least one cooking area configured to accommodate a heating element proximate to the top surface;
• suction means in fluid communication with the suction opening and configured to draw in cooking fumes;
• a support element connected to the main body;
• and
• weight sensing means between the support element and the main body for sensing a weight of objects to be weighed;
• wherein the support element at least partially overlaps the suction means,
• wherein the suction means comprises:
• a suction duct in fluid communication with the suction opening;
• and
• a housing in fluid communication with the suction duct and configured to receive filters for the cooking fumes;
• wherein the weight sensing means is at the suction duct and/or the housing,
• wherein the suction opening is on the top surface and the suction opening is coplanar with the housing,
• wherein the support element is superimposed to the suction opening and to the housing,
• wherein the weight sensing means comprises at least one load cell,
• wherein the support element comprises a panel,
• wherein the at least one load cell is along a perimeter of the panel,
• wherein the panel has a plurality of support areas, each support area at a respective load cell,
• wherein the main body has a plurality of receptacles, each receptacle at a respective load cell and surrounding the respective load cell, and
