<p>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.</p> |
