A cooking hob comprising:

• a body configured to act as a support for the cooking activity and having an upper surface and a lower surface;
• at least one cooking zone located at the upper surface of the body;
• a suction opening formed on said upper surface;
• suction elements placed in fluid communication with said suction opening (4) and configured to suck cooking fumes;
• wherein:
• said suction elements comprise a motor fan having a rotation axis, said motor fan extending between a first and a opposite second end along said rotation axis;
• said suction elements being configured to divide the cooking fumes into a first and a second portion of the cooking fumes directed respectively towards the first and the second end of the motor fan;
• the axis of rotation lies in a plane parallel to the upper surface
• the suction elements comprise a first and a second suction duct in fluid communication with the suction opening and respectively with the first and the second end of the motor fan, the fluid dynamic resistance of said first suction duct being substantially equal to the fluid dynamic resistance of said second suction duct;
• said motor fan being configured to suck the first portion of the cooking fumes through said first suction duct and the second portion of the cooking fumes through said second suction duct;
• the cooking hob comprises an operating unit for the operation of the cooking hob, for the control thereof and for the outflow of cooking vapors through said first and second suction duct and configured to contain at least one heating element capable of heating the at least one cooking zone and a command and control electronics of the cooking hob, said operating unit being arranged below said body of the cooking hob;
• the cooking hob comprises a pair of covering casings connected to each other so as to define a housing, said motor fan being arranged in the housing, said pair of covering casing defining the first and the second suction duct, wherein the covering casings are arranged and constrained below said operating unit and at least one covering casing is reversibly constrained to said operating unit to allow the motor fan to be reached.
