(57) A hob assembly for a range cooker (1) comprises a base having a heating zone (8,
9), a heating means comprising at least one electric heating element, a thermally
insulated lid (8a,9a) which can be moved between a closed position in which it covers
the heating zone (8, 9) and permits a controlled amount of heat from the heating (8,
9) zone to escape through the lid (8a,9a) and an open position in which it is open
to allow a pan to placed on the heating zone (8, 9), and a control means for controlling
the operation of the heating means when in use. During use of the hob assembly when the heating zone (8, 9) is switched on and the
insulated lid (8a,9a) is closed the control means is adapted to apply a current to
the heating means to maintain the temperature at a predefined value suitable for cooking
and in the event that the lid (8a,9a) is subsequently opened the control means automatically
causes more current to be applied to the heating means in order to attempt to maintain
the temperature of the heating zone (8, 9) close to the predefined value.
