A pressure cooker includes: a base and a lid, wherein the lid includes a mechanical pressure release mechanism. Upon the activation of a solenoid within the base of the pressure cooker, the pressure release mechanism is configured to lift a valve cover, so as to allow steam to be released from an interior chamber of the cooker. Upon deactivation of the solenoid, the pressure release mechanism is configured to return in an initial resting condition, with the valve cover resealing the interior chamber of the cooker.

A cooking appliance includes a base including an upper surface having a cooktop, and a lid separable from the base, and including a heater assembly disposed therein. The cooking appliance further includes a control unit configured to operate at least one of the cooktop in the base or the heater assembly in the lid.

An electrical appliance for cooking food by two different methods is disclosed. Generally speaking, the appliance comprises a base and two interchangeable cooking lids. The base has an outer surface, an inner cooking chamber open at an upper end, a first heating source coupled to the cooking chamber, an electronic controller for controlling the heating source, and a user interface having a plurality of buttons for inputting cooking parameters to the electronic controller.
