  • Patent number: 4307287
    Abstract: The electric cooking appliance has a casing for receiving a removable vessel in which food to be cooked is placed. An electrical heating element is provided in the casing for heating the vessel. The supply of electrical power to the heating element is controlled by a control device including a supply switch and a manually settable control circuit arranged during the normal cooking phase to intermittently place the supply switch in its conducting state so that power is supplied to the heating element intermittently. Prior to the normal cooking phase, the control circuit maintains the supply switch continuously in its conducting state for an initial period of time which is independent of the manual setting of the control circuit.
