Abstract: A kitchen worktop having a support plate (2) with a treatment area (4) on which a container is placed (50), and a heating device (34) located in the treatment area under the support plate. Weight transducers (38) are fixed both to the support plate (2) and to a movable portion (24a) of a series of actuators (24), the fixed portion (24b) of which is fixed to a structure (11). A control device allows activating the actuators (24) in order to move the weight transducers (38) and the support plate (2) between a rest position in which the support plate (2) rests on the structure (11), and a weighing position in which the support plate (2) is supported only by the weight transducers (38) in order to enable a weighing operation.
