The invention discloses a program controlled stove capable of playing video cooking teaching courses, which is provided with one or more electric heating devices, and a cooking menu database which stores a plurality of cooking programs, wherein each cooking program can contain a plurality of cooking procedures; after a user selects one cooking program on a user interface and starts the cooking program, the stove can automatically select the heating devices for the stove one by one, and automatically control the output power and the duration of the heating devices such as a magnetron and a light wave tube to cook food according to the requirements of parameters such as heating modes, fire, temperature, duration and so on specified by each cooking procedure of the cooking program; at the same time, the stove compares values acquired in a real-time mode such as temperature and timing duration with the parameters during the cooking process to automatically adjust the cooking process until each procedure of the cooking program is finished; in addition, the stove also comprises a media player which can play video teaching courses of the cooking programs and instruct users how to prepare cooking materials and what important items need to be noticed and so on.

A cooking device for cooking items over a heat source has a base with an annular reservoir having an inside rim defining an opening, a substantially circular cooking plate supported by the base, a rack supported by the base over the cooking plate, and a lid supported by the base over the cooking plate and the rack. The base of the cooking device has an annular cooking plate supporting surface located radially outwardly from an outside rim of the annular reservoir, an annular rack supporting surface located radially outwardly from the cooking plate supporting surface, an annular lid supporting surface located radially outwardly from the rack supporting surface, an outer rim projecting radially outwardly and upwardly from the lid supporting surface, an upwardly-projecting annular sealing portion located intermediate the rack supporting portion and the lid supporting portion, an annular cooking plate retaining surface disposed radially outwardly from the cooking plate supporting surface, and discrete support elements projecting downwardly from the base. A reversible cooking plate has a grilling surface on one side and a griddle surface on an opposite side. In one position, the grilling surface is directed upwardly and is inclined at an angle, in a second position, the griddle surface is directed upwardly and is substantially horizontal. A rim of varying height extends around the periphery of the griddle surface and aligns the griddle surface at an angle when in the first position.
